-2003-07-14 Simon J. Gerraty <sjg at void.crufty.net>
-
- * Makefile.in: BMAKE_VERSION switch to a date based version.

-
-2003-07-11 Simon J. Gerraty <sjg at void.crufty.net>
-
- * FILES: include boot-strap and os.sh
-
- * Makefile.in: only set WARNS if we are NetBSD, the effect on

-
- * makefile.boot.in (bootstrap): make this the default target.
-
- * Makefile.in: bump version to 3.1.19
-
- * machine.sh: avoid A-Z with tr as it is bound to lose.
-
-2003-07-10 Simon J. Gerraty <sjg at void.crufty.net>

- Plus some doc fixes.
-
-2003-04-27 Simon J. Gerraty <sjg at void.crufty.net>
-
- * Merge with NetBSD make
- Pick up fix for PR/1523 - don't count a library as built, if there
- is no way to build it
-
- * Bump version to 3.1.18
-
-2003-03-23 Simon J. Gerraty <sjg at void.crufty.net>
-

-
-2003-03-21 Simon J. Gerraty <sjg at void.crufty.net>
-
- * Merge with NetBSD make (mmm 10th anniversary!)
- pick up fix for .WAIT in srcs that refer to $@ or $* (PR#20828)

-
-2002-12-03 Simon J. Gerraty <sjg at void.crufty.net>
-
- * makefile.boot.in (bmake): update install targets for those that

-
- * bmake.cat1: update the pre-formatted man page!
-
-2002-11-30 Simon J. Gerraty <sjg at void.crufty.net>
-
- * Merge with NetBSD make.
- pick up fix for premature free of pointer used in call
- to Dir_InitCur().
- set MAKE_VERSION to 3.1.15
-
-2002-11-26 Simon J. Gerraty <sjg at void.crufty.net>
-
- * configure.in: determine suitable value for MKSRC.
- override using --with-mksrc=PATH.
-
- * machine.sh: use `uname -p` for MACHINE_ARCH on modern SunOS systems.
- configs(8) will use 'sun4' as an alias for 'sparc'.
-
-2002-11-25 Simon J. Gerraty <sjg at void.crufty.net>
-
- * Merge with NetBSD make.
- pick up ${.PATH}
- pick up fix for finding ../cat.c via .PATH when .CURDIR=..
- set MAKE_VERSION to 3.1.14
- add configure checks for killpg and sys/socket.h
-
-2002-09-16 Simon J. Gerraty <sjg at void.crufty.net>
-
- * tag bmake-3-1-13
-
- * makefile.boot.in (bmake): use install-mk
- Also setup ./mk before trying to invoke bmake.boot incase we
- needed install-mk to create a sys.mk for us.
-
- * configure.in: If we need to add -I${srcdir}/missing, make it an
- absolute path so that it works for lst.lib too.
-
- * make.h: always include sys/cdefs.h since we provide one if the
- host does not.
-
- * Makefile.in (install-mk):
- use MKSRC/install-mk which will do the right thing.
- use uname -p for ARCH if possible.
- since install-mk will setup links bsd.prog.mk -> prog.mk if
- needed, just .include bsd.prog.mk
-
- * Merge with NetBSD make (NetBSD-1.6)
- Code is ansi-C only now.
- Bug in handling of dotLast is fixed.
- Can now assign .OBJDIR and make will reset its notions of life.
- New modifiers :tu :tl for toUpper and toLower.
-
-Tue Oct 16 12:18:42 2001 Simon J. Gerraty <sjg at zen.crufty.net>
-
- * Merge with NetBSD make
- pick up fix for .END failure in compat mode.
- pick up fix for extra va_end() in ParseVErrorInternal.
-
-Thu Oct 11 13:20:06 2001 Simon J. Gerraty <sjg at zen.crufty.net>
-
- * configure.in: for systems that have sys/cdefs.h check if it is
- compatible. If not, include the one under missing, but tell it to
- include the native one too - necessary on Linux.
-
- * missing/sys/cdefs.h: if NEED_HOST_CDEFS_H is defined, use
- include_next (for gcc) to get the native sys/cdefs.h
-
-Tue Aug 21 02:29:34 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * job.c (JobFinish): Fix an earlier merge bug that resulted in
- leaking descriptors when using -jN.
-
- * job.c (JobPrintCommand): See if "curdir" exists before
- attempting to chdir(). Doing the chdir directly in make (when in
- compat mode) fails silently, so let the -jN version do the same.
- This can happen when building kernels in an object tree and
- playing clever games to reset .CURDIR.
-
- * Merged with NetBSD make
- pick up .USEBEFORE
-
-Tue Jun 26 23:45:11 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * makefile.boot.in: Give bmake.boot a MAKESYSPATH that might work.
-
-Tue Jun 12 16:48:57 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * var.c (Var_Set): Add 4th (flags) arg so VarLoopExpand can tell
- us not to export the iterator variable when using VAR_CMD context.
-
-Sun Jun 10 21:55:21 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * job.c (Job_CatchChildren): don't call Job_CatchOutput() here,
- its the wrong "fix".
-
-Sat Jun 9 00:11:24 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * Redesigned export of VAR_CMD's via MAKEFLAGS.
- We now simply append the variable names to .MAKEOVERRIDES, and
- handle duplicate suppression and quoting in ExportMAKEFLAGS using:
- ${.MAKEOVERRIDES:O:u:@v@$v=${$v:Q}@}
- Apart from fixing quoting bugs in previous version, this allows us
- to export vars to the environment by simply doing:
- .MAKEOVERRIDES+= PATH
- Merged again with NetBSD make, but the above is the only change.
-
- * configure.in: added
- --disable-pwd-override disable $PWD overriding getcwd()
- --disable-check-make-chdir disable make trying to guess
- when it should automatically cd ${.CURDIR}
-
- * Merge with NetBSD make, changes include:
- parse.c (ParseDoDependency): Spot that the syntax error is
- caused by an unresolved cvs/rcs conflict and say so.
- var.c: most of Var* functions now take a ctxt as 1st arg.
- now does variable substituion on rhs of sysv style modifiers.
-
- * var.c (Var_Set): exporting of command line variables (VAR_CMD)
- is now done here. We append the name='value' to .MAKEOVERRIDES
- rather than directly into MAKEFLAGS as this allows a Makefile to
- use .MAKEOVERRIDES= to disable this behaviour. GNU make uses a
- very similar mechanism. Note that in adding name='value' to
- .MAKEOVERRIDES we do the moral equivalent of:
- .MAKEOVERRIDES:= ${.MAKEOVERRIDES:Nname=*} name='val'
-
-Fri Jun 1 14:08:02 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * make-conf.h (USE_IOVEC): make it conditional on HAVE_SYS_UIO_H
-
- * Merged with NetBSD make
- make -dx can now be used to run commands via sh -x
- better error messages on exec failures.
-
-Thu May 31 01:44:54 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * Makefile.in (main.o): depends on ${SRCS} ${MAKEFILE} so that
- MAKE_VERSION gets updated. Also don't use ?= for MAKE_VERSION,
- MACHINE etc otherwise they propagate from the previous bmake.
-
- * configure.in (machine): allow --with-machine=generic to make
- configure use machine.sh to set MACHINE.
-
- * job.c (JobInterrupt): convert to using WAIT_T and friends.
-
- * Makefile.in: mention in bmake.1 that we use autoconf.
-
- * make.1: mention MAKE_PRINT_VAR_ON_ERROR.
-
-Wed May 30 23:17:18 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * main.c (ReadMakefile): don't set MAKEFILE if reading ".depend"
- as that rather defeats the usefulness of ${MAKEFILE}.
-
- * main.c (MainParseArgs): append command line variable assignments
- to MAKEFLAGS so that they get propagated to child make's.
- Apparently this is required POSIX behaviour? Its useful anyway.
-
-Tue May 29 02:20:07 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * compat.c (CompatRunCommand): don't use perror() since stdio may
- cause problems in child of vfork().
-
- * compat.c, main.c: Call PrintOnError() when we are going to bail.
- This routine prints out the .curdir where we stopped and will also
- display any vars listed in ${MAKE_PRINT_VAR_ON_ERROR}.
-
- * main.c: add ${.newline} to hold a "\n" - sometimes handy in
- :@ expansion.
-
- * var.c: VarLoopExpand: ignore addSpace if a \n is present.
-
- * Added RCSid's for the files we've touched.
-
-Thu May 24 15:41:37 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * configure.in: Thanks to some clues from mdb at juniper.net,
- added autoconf magic to control setting of MACHINE, MACHINE_ARCH
- as well as what ends up in _PATH_DEFSYSPATH. We now have:
-
- --with-machine=MACHINE explicitly set MACHINE
- --with-force-machine=MACHINE set FORCE_MACHINE
- --with-machine_arch=MACHINE_ARCH explicitly set MACHINE_ARCH
- --with-default-sys-path=PATH:DIR:LIST use an explicit _PATH_DEFSYSPATH
- --with-prefix-sys-path=PATH:DIR:LIST prefix _PATH_PREFIX_SYSPATH
- --with-path-objdirprefix=PATH override _PATH_OBJDIRPREFIX
-
- If _PATH_OBJDIRPREFIX is set to "no" we won't define it.
-
- * makefile: added a pathetically simple makefile to drive
- bootstrapping. Running configure by hand is more useful.
-
- * Makefile.in: added MAKE_VERSION, and reworked things to be less
- dependent on NetBSD bsd.*.mk
-
- * pathnames.h: allow NO_PATH_OBJDIRPREFIX to stop us defining
- _PATH_OBJDIRPREFIX for those that don't want a default.
- construct _PATH_DEFSYSPATH from the info we get from configure.
-
- * main.c: allow for no _PATH_OBJDIRPREFIX, set ${MAKE_VERSION}
- if MAKE_VERSION is defined.
-
- * compat.c: when we bail, print out the .CURDIR we were in.
-
-Sat May 12 00:34:12 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * Merged with NetBSD make
-
- * var.c: fixed a bug in the handling of the modifier :P
- if the node as found but the path was null, we segfault trying to
- duplicate it.
-
-Mon Mar 5 16:20:33 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * Merged with NetBSD make
-
- * make.c: Make_OODate's test for a library out of date was using
- cmtime where it should have used mtime (my bug).
-
- * compat.c: Use perror() to tell us what really went wrong when we
- cannot exec a command.
-
-Fri Dec 15 10:11:08 2000 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * Merged with NetBSD make
-
-Sat Jun 10 10:11:08 2000 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * Merged with NetBSD make
-
-Thu Jun 1 10:11:08 2000 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * Merged with NetBSD make
-
-Tue May 30 10:11:08 2000 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * Merged with NetBSD make
-
-Thu Apr 27 00:07:47 2000 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * util.c: don't provide signal() since we use sigcompat.c
-
- * Makefile.in: added a build target.
-
- * var.c (Var_Parse): added ODE modifiers :U, :D, :L, :P, :@ and :!
- These allow some quite clever magic.
-
- * main.c (main): added support for getenv(MAKESYSPATH).
-
-Mon Apr 2 16:25:13 2000 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * Disable $PWD overriding getcwd() if MAKEOBJDIRPREFIX is set.
- This avoids objdir having a different value depending on how a
- directory was reached (via command line, or subdir.mk).
-
- * If FORCE_MACHINE is defined, ignore getenv("MACHINE").
-
-Mon Apr 2 23:15:31 2000 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * Do a chdir(${.CURDIR}) before invoking ${.MAKE} or ${.MAKE:T} if
- MAKEOBJDIRPREFIX is set and NOCHECKMAKECHDIR is not.
- I've been testing this in NetBSD's make for some weeks.
-
- * Turn Makefile into Makefile.in and make it useful.
-
-Tue Feb 29 22:08:00 2000 Simon J. Gerraty <sjg at zen.quick.com.au>
-
- * Imported NetBSD's -current make(1) and resolve conflicts.
-
- * Applied autoconf patches from bmake v2
-
- * Imported clean code base from NetBSD-1.0

+
+Tue Aug 21 02:29:34 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * job.c (JobFinish): Fix an earlier merge bug that resulted in
+ leaking descriptors when using -jN.
+
+ * job.c (JobPrintCommand): See if "curdir" exists before
+ attempting to chdir(). Doing the chdir directly in make (when in
+ compat mode) fails silently, so let the -jN version do the same.
+ This can happen when building kernels in an object tree and
+ playing clever games to reset .CURDIR.
+
+ * Merged with NetBSD make
+ pick up .USEBEFORE
+
+Tue Jun 26 23:45:11 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * makefile.boot.in: Give bmake.boot a MAKESYSPATH that might work.
+
+Tue Jun 12 16:48:57 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * var.c (Var_Set): Add 4th (flags) arg so VarLoopExpand can tell
+ us not to export the iterator variable when using VAR_CMD context.
+
+Sun Jun 10 21:55:21 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * job.c (Job_CatchChildren): don't call Job_CatchOutput() here,
+ its the wrong "fix".
+
+Sat Jun 9 00:11:24 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * Redesigned export of VAR_CMD's via MAKEFLAGS.
+ We now simply append the variable names to .MAKEOVERRIDES, and
+ handle duplicate suppression and quoting in ExportMAKEFLAGS using:
+ ${.MAKEOVERRIDES:O:u:@v@$v=${$v:Q}@}
+ Apart from fixing quoting bugs in previous version, this allows us
+ to export vars to the environment by simply doing:
+ .MAKEOVERRIDES+= PATH
+ Merged again with NetBSD make, but the above is the only change.
+
+ * configure.in: added
+ --disable-pwd-override disable $PWD overriding getcwd()
+ --disable-check-make-chdir disable make trying to guess
+ when it should automatically cd ${.CURDIR}
+
+ * Merge with NetBSD make, changes include:
+ parse.c (ParseDoDependency): Spot that the syntax error is
+ caused by an unresolved cvs/rcs conflict and say so.
+ var.c: most of Var* functions now take a ctxt as 1st arg.
+ now does variable substituion on rhs of sysv style modifiers.
+
+ * var.c (Var_Set): exporting of command line variables (VAR_CMD)
+ is now done here. We append the name='value' to .MAKEOVERRIDES
+ rather than directly into MAKEFLAGS as this allows a Makefile to
+ use .MAKEOVERRIDES= to disable this behaviour. GNU make uses a
+ very similar mechanism. Note that in adding name='value' to
+ .MAKEOVERRIDES we do the moral equivalent of:
+ .MAKEOVERRIDES:= ${.MAKEOVERRIDES:Nname=*} name='val'
+
+Fri Jun 1 14:08:02 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * make-conf.h (USE_IOVEC): make it conditional on HAVE_SYS_UIO_H
+
+ * Merged with NetBSD make
+ make -dx can now be used to run commands via sh -x
+ better error messages on exec failures.
+
+Thu May 31 01:44:54 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * Makefile.in (main.o): depends on ${SRCS} ${MAKEFILE} so that
+ MAKE_VERSION gets updated. Also don't use ?= for MAKE_VERSION,
+ MACHINE etc otherwise they propagate from the previous bmake.
+
+ * configure.in (machine): allow --with-machine=generic to make
+ configure use machine.sh to set MACHINE.
+
+ * job.c (JobInterrupt): convert to using WAIT_T and friends.
+
+ * Makefile.in: mention in bmake.1 that we use autoconf.
+
+ * make.1: mention MAKE_PRINT_VAR_ON_ERROR.
+
+Wed May 30 23:17:18 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * main.c (ReadMakefile): don't set MAKEFILE if reading ".depend"
+ as that rather defeats the usefulness of ${MAKEFILE}.
+
+ * main.c (MainParseArgs): append command line variable assignments
+ to MAKEFLAGS so that they get propagated to child make's.
+ Apparently this is required POSIX behaviour? Its useful anyway.
+
+Tue May 29 02:20:07 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * compat.c (CompatRunCommand): don't use perror() since stdio may
+ cause problems in child of vfork().
+
+ * compat.c, main.c: Call PrintOnError() when we are going to bail.
+ This routine prints out the .curdir where we stopped and will also
+ display any vars listed in ${MAKE_PRINT_VAR_ON_ERROR}.
+
+ * main.c: add ${.newline} to hold a "\n" - sometimes handy in
+ :@ expansion.
+
+ * var.c: VarLoopExpand: ignore addSpace if a \n is present.
+
+ * Added RCSid's for the files we've touched.
+
+Thu May 24 15:41:37 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * configure.in: Thanks to some clues from mdb at juniper.net,
+ added autoconf magic to control setting of MACHINE, MACHINE_ARCH
+ as well as what ends up in _PATH_DEFSYSPATH. We now have:
+
+ --with-machine=MACHINE explicitly set MACHINE
+ --with-force-machine=MACHINE set FORCE_MACHINE
+ --with-machine_arch=MACHINE_ARCH explicitly set MACHINE_ARCH
+ --with-default-sys-path=PATH:DIR:LIST use an explicit _PATH_DEFSYSPATH
+ --with-prefix-sys-path=PATH:DIR:LIST prefix _PATH_PREFIX_SYSPATH
+ --with-path-objdirprefix=PATH override _PATH_OBJDIRPREFIX
+
+ If _PATH_OBJDIRPREFIX is set to "no" we won't define it.
+
+ * makefile: added a pathetically simple makefile to drive
+ bootstrapping. Running configure by hand is more useful.
+
+ * Makefile.in: added MAKE_VERSION, and reworked things to be less
+ dependent on NetBSD bsd.*.mk
+
+ * pathnames.h: allow NO_PATH_OBJDIRPREFIX to stop us defining
+ _PATH_OBJDIRPREFIX for those that don't want a default.
+ construct _PATH_DEFSYSPATH from the info we get from configure.
+
+ * main.c: allow for no _PATH_OBJDIRPREFIX, set ${MAKE_VERSION}
+ if MAKE_VERSION is defined.
+
+ * compat.c: when we bail, print out the .CURDIR we were in.
+
+Sat May 12 00:34:12 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * Merged with NetBSD make
+
+ * var.c: fixed a bug in the handling of the modifier :P
+ if the node as found but the path was null, we segfault trying to
+ duplicate it.
+
+Mon Mar 5 16:20:33 2001 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * Merged with NetBSD make
+
+ * make.c: Make_OODate's test for a library out of date was using
+ cmtime where it should have used mtime (my bug).
+
+ * compat.c: Use perror() to tell us what really went wrong when we
+ cannot exec a command.
+
+Fri Dec 15 10:11:08 2000 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * Merged with NetBSD make
+
+Sat Jun 10 10:11:08 2000 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * Merged with NetBSD make
+
+Thu Jun 1 10:11:08 2000 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * Merged with NetBSD make
+
+Tue May 30 10:11:08 2000 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * Merged with NetBSD make
+
+Thu Apr 27 00:07:47 2000 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * util.c: don't provide signal() since we use sigcompat.c
+
+ * Makefile.in: added a build target.
+
+ * var.c (Var_Parse): added ODE modifiers :U, :D, :L, :P, :@ and :!
+ These allow some quite clever magic.
+
+ * main.c (main): added support for getenv(MAKESYSPATH).
+
+Mon Apr 2 16:25:13 2000 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * Disable $PWD overriding getcwd() if MAKEOBJDIRPREFIX is set.
+ This avoids objdir having a different value depending on how a
+ directory was reached (via command line, or subdir.mk).
+
+ * If FORCE_MACHINE is defined, ignore getenv("MACHINE").
+
+Mon Apr 2 23:15:31 2000 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * Do a chdir(${.CURDIR}) before invoking ${.MAKE} or ${.MAKE:T} if
+ MAKEOBJDIRPREFIX is set and NOCHECKMAKECHDIR is not.
+ I've been testing this in NetBSD's make for some weeks.
+
+ * Turn Makefile into Makefile.in and make it useful.
+
+Tue Feb 29 22:08:00 2000 Simon J. Gerraty <sjg at zen.quick.com.au>
+
+ * Imported NetBSD's -current make(1) and resolve conflicts.
+
+ * Applied autoconf patches from bmake v2
+
+ * Imported clean code base from NetBSD-1.0

-.xH 1 Introduction
-.LP
-PMake is a program for creating other programs, or anything else you
-can think of for it to do. The basic idea behind PMake is that, for
-any given system, be it a program or a document or whatever, there
-will be some files that depend on the state of other files (on when
-they were last modified). PMake takes these dependencies, which you
-must specify, and uses them to build whatever it is you want it to
-build.
-.LP
-PMake is almost fully-compatible with Make, with which you may already
-be familiar. PMake's most important feature is its ability to run
-several different jobs at once, making the creation of systems
-considerably faster. It also has a great deal more functionality than
-Make. Throughout the text, whenever something is mentioned that is an
-important difference between PMake and Make (i.e. something that will
-cause a makefile to fail if you don't do something about it), or is
-simply important, it will be flagged with a little sign in the left
-margin, like this:
-.No
-.LP
-This tutorial is divided into three main sections corresponding to basic,
-intermediate and advanced PMake usage. If you already know Make well,
-you will only need to skim chapter 2 (there are some aspects of
-PMake that I consider basic to its use that didn't exist in Make).
-Things in chapter 3 make life much easier, while those in chapter 4
-are strictly for those who know what they are doing. Chapter 5 has
-definitions for the jargon I use and chapter 6 contains possible
-solutions to the problems presented throughout the tutorial.
-.xH 1 The Basics of PMake
-.LP
-PMake takes as input a file that tells a) which files depend on which
-other files to be complete and b) what to do about files that are
-``out-of-date.'' This file is known as a ``makefile'' and is usually
-.Ix 0 def makefile
-kept in the top-most directory of the system to be built. While you
-can call the makefile anything you want, PMake will look for
-.CW Makefile
-and
-.CW makefile
-(in that order) in the current directory if you don't tell it
-otherwise.
-.Ix 0 def makefile default
-To specify a different makefile, use the
-.B \-f
-flag (e.g.
-.CW "pmake -f program.mk" ''). ``
-.Ix 0 ref flags -f
-.Ix 0 ref makefile other
-.LP
-A makefile has four different types of lines in it:
-.RS
-.IP \(bu 2
-File dependency specifications
-.IP \(bu 2
-Creation commands
-.IP \(bu 2
-Variable assignments
-.IP \(bu 2
-Comments, include statements and conditional directives
-.RE
-.LP
-Any line may be continued over multiple lines by ending it with a
-backslash.
-.Ix 0 def "continuation line"
-The backslash, following newline and any initial whitespace
-on the following line are compressed into a single space before the
-input line is examined by PMake.
-.xH 2 Dependency Lines
-.LP
-As mentioned in the introduction, in any system, there are
-dependencies between the files that make up the system. For instance,
-in a program made up of several C source files and one header file,
-the C files will need to be re-compiled should the header file be
-changed. For a document of several chapters and one macro file, the
-chapters will need to be reprocessed if any of the macros changes.
-.Ix 0 def "dependency"
-These are dependencies and are specified by means of dependency lines in
-the makefile.
-.LP
-.Ix 0 def "dependency line"
-On a dependency line, there are targets and sources, separated by a
-one- or two-character operator.
-The targets ``depend'' on the sources and are usually created from
-them.
-.Ix 0 def target
-.Ix 0 def source
-.Ix 0 ref operator
-Any number of targets and sources may be specified on a dependency line.
-All the targets in the line are made to depend on all the sources.
-Targets and sources need not be actual files, but every source must be
-either an actual file or another target in the makefile.
-If you run out of room, use a backslash at the end of the line to continue onto
-the next one.
-.LP
-Any file may be a target and any file may be a source, but the
-relationship between the two (or however many) is determined by the
-``operator'' that separates them.
-.Ix 0 def operator
-Three types of operators exist: one specifies that the datedness of a
-target is determined by the state of its sources, while another
-specifies other files (the sources) that need to be dealt with before
-the target can be re-created. The third operator is very similar to
-the first, with the additional condition that the target is
-out-of-date if it has no sources. These operations are represented by
-the colon, the exclamation point and the double-colon, respectively, and are
-mutually exclusive. Their exact semantics are as follows:
-.IP ":"
-.Ix 0 def operator colon
-.Ix 0 def :
-If a colon is used, a target on the line is considered to be
-``out-of-date'' (and in need of creation) if
-.RS
-.IP \(bu 2
-any of the sources has been modified more recently than the target, or
-.IP \(bu 2
-the target doesn't exist.
-.RE
-.Ix 0 def out-of-date
-.IP "\&"
-Under this operation, steps will be taken to re-create the target only
-if it is found to be out-of-date by using these two rules.
-.IP "!"
-.Ix 0 def operator force
-.Ix 0 def !
-If an exclamation point is used, the target will always be re-created,
-but this will not happen until all of its sources have been examined
-and re-created, if necessary.
-.IP "::"
-.Ix 0 def operator double-colon
-.Ix 0 def ::
-If a double-colon is used, a target is out-of-date if:
-.RS
-.IP \(bu 2
-any of the sources has been modified more recently than the target, or
-.IP \(bu 2
-the target doesn't exist, or
-.IP \(bu 2
-the target has no sources.
-.RE
-.IP "\&"
-If the target is out-of-date according to these rules, it will be re-created.
-This operator also does something else to the targets, but I'll go
-into that in the next section (``Shell Commands'').
-.LP
-Enough words, now for an example. Take that C program I mentioned
-earlier. Say there are three C files
-.CW a.c , (
-.CW b.c
-and
-.CW c.c )
-each of which
-includes the file
-.CW defs.h .
-The dependencies between the files could then be expressed as follows:
-.DS
-program : a.o b.o c.o
-a.o b.o c.o : defs.h
-a.o : a.c
-b.o : b.c
-c.o : c.c
-.DE
-.LP
-You may be wondering at this point, where
-.CW a.o ,
-.CW b.o
-and
-.CW c.o
-came in and why
-.I they
-depend on
-.CW defs.h
-and the C files don't. The reason is quite simple:
-.CW program
-cannot be made by linking together .c files \*- it must be
-made from .o files. Likewise, if you change
-.CW defs.h ,
-it isn't the .c files that need to be re-created, it's the .o files.
-If you think of dependencies in these terms \*- which files (targets)
-need to be created from which files (sources) \*- you should have no problems.
-.LP
-An important thing to notice about the above example, is that all the
-\&.o files appear as targets on more than one line. This is perfectly
-all right: the target is made to depend on all the sources mentioned
-on all the dependency lines. E.g.
-.CW a.o
-depends on both
-.CW defs.h
-and
-.CW a.c .
-.Ix 0 ref dependency
-.No
-.LP
-The order of the dependency lines in the makefile is
-important: the first target on the first dependency line in the
-makefile will be the one that gets made if you don't say otherwise.
-That's why
-.CW program
-comes first in the example makefile, above.
-.LP
-Both targets and sources may contain the standard C-Shell wildcard
-characters
-.CW { , (
-.CW } ,
-.CW * ,
-.CW ? ,
-.CW [ ,
-and
-.CW ] ),
-but the non-curly-brace ones may only appear in the final component
-(the file portion) of the target or source. The characters mean the
-following things:
-.IP \fB{}\fP
-These enclose a comma-separated list of options and cause the pattern
-to be expanded once for each element of the list. Each expansion
-contains a different element. For example,
-.CW src/{whiffle,beep,fish}.c
-expands to the three words
-.CW src/whiffle.c ,
-.CW src/beep.c ,
-and
-.CW src/fish.c .
-These braces may be nested and, unlike the other wildcard characters,
-the resulting words need not be actual files. All other wildcard
-characters are expanded using the files that exist when PMake is
-started.
-.IP \fB*\fP
-This matches zero or more characters of any sort.
-.CW src/*.c
-will expand to the same three words as above as long as
-.CW src
-contains those three files (and no other files that end in
-.CW .c ).
-.IP \fB?\fP
-Matches any single character.
-.IP \fB[]\fP
-This is known as a character class and contains either a list of
-single characters, or a series of character ranges
-.CW a-z , (
-for example means all characters between a and z), or both. It matches
-any single character contained in the list. E.g.
-.CW [A-Za-z]
-will match all letters, while
-.CW [0123456789]
-will match all numbers.
-.xH 2 Shell Commands
-.LP
-``Isn't that nice,'' you say to yourself, ``but how are files
-actually `re-created,' as he likes to spell it?''
-The re-creation is accomplished by commands you place in the makefile.
-These commands are passed to the Bourne shell (better known as
-``/bin/sh'') to be executed and are
-.Ix 0 ref shell
-.Ix 0 ref re-creation

-Shell commands in a makefile look a lot like shell commands you would
-type at a terminal, with one important exception: each command in a
-makefile
-.I must
-be preceded by at least one tab.
-.LP
-Each target has associated with it a shell script made up of
-one or more of these shell commands. The creation script for a target
-should immediately follow the dependency line for that target. While
-any given target may appear on more than one dependency line, only one
-of these dependency lines may be followed by a creation script, unless
-the `::' operator was used on the dependency line.
-.Ix 0 ref operator double-colon

-If the double-colon was used, each dependency line for the target
-may be followed by a shell script. That script will only be executed
-if the target on the associated dependency line is out-of-date with
-respect to the sources on that line, according to the rules I gave
-earlier.
-I'll give you a good example of this later on.
-.LP
-To expand on the earlier makefile, you might add commands as follows:
-.DS
-program : a.o b.o c.o
- cc a.o b.o c.o \-o program
-a.o b.o c.o : defs.h
-a.o : a.c
- cc \-c a.c
-b.o : b.c
- cc \-c b.c
-c.o : c.c
- cc \-c c.c
-.DE
-.LP
-Something you should remember when writing a makefile is, the
-commands will be executed if the
-.I target
-on the dependency line is out-of-date, not the sources.
-.Ix 0 ref target
-.Ix 0 ref source
-.Ix 0 ref out-of-date
-In this example, the command
-.CW "cc \-c a.c" '' ``
-will be executed if
-.CW a.o
-is out-of-date. Because of the `:' operator,
-.Ix 0 ref :
-.Ix 0 ref operator colon
-this means that should
-.CW a.c

-.CW defs.h
-have been modified more recently than
-.CW a.o ,
-the command will be executed
-.CW a.o "\&" (
-will be considered out-of-date).
-.Ix 0 ref out-of-date
-.LP
-Remember how I said the only difference between a makefile shell
-command and a regular shell command was the leading tab? I lied. There
-is another way in which makefile commands differ from regular ones.
-The first two characters after the initial whitespace are treated
-specially.
-If they are any combination of `@' and `\-', they cause PMake to do
-different things.
-.LP
-In most cases, shell commands are printed before they're
-actually executed. This is to keep you informed of what's going on. If
-an `@' appears, however, this echoing is suppressed. In the case of an
-.CW echo
-command, say
-.CW "echo Linking index" ,'' ``
-it would be
-rather silly to see
-.DS
-echo Linking index
-Linking index
-.DE
-.LP
-so PMake allows you to place an `@' before the command
-.CW "@echo Linking index" '') (``
-to prevent the command from being printed.
-.LP
-The other special character is the `\-'. In case you didn't know,
-shell commands finish with a certain ``exit status.'' This status is
-made available by the operating system to whatever program invoked the
-command. Normally this status will be 0 if everything went ok and
-non-zero if something went wrong. For this reason, PMake will consider
-an error to have occurred if one of the shells it invokes returns a non-zero
-status. When it detects an error, PMake's usual action is to abort
-whatever it's doing and exit with a non-zero status itself (any other
-targets that were being created will continue being made, but nothing
-new will be started. PMake will exit after the last job finishes).
-This behavior can be altered, however, by placing a `\-' at the front
-of a command
-.CW "\-mv index index.old" ''), (``
-certain command-line arguments,
-or doing other things, to be detailed later. In such
-a case, the non-zero status is simply ignored and PMake keeps chugging
-along.
-.No
-.LP
-Because all the commands are given to a single shell to execute, such
-things as setting shell variables, changing directories, etc., last
-beyond the command in which they are found. This also allows shell
-compound commands (like
-.CW for
-loops) to be entered in a natural manner.
-Since this could cause problems for some makefiles that depend on
-each command being executed by a single shell, PMake has a
-.B \-B
-.Ix 0 ref compatibility
-.Ix 0 ref flags -B
-flag (it stands for backwards-compatible) that forces each command to
-be given to a separate shell. It also does several other things, all
-of which I discourage since they are now old-fashioned.\|.\|.\|.
-.No
-.LP
-A target's shell script is fed to the shell on its (the shell's) input stream.
-This means that any commands, such as
-.CW ci
-that need to get input from the terminal won't work right \*- they'll
-get the shell's input, something they probably won't find to their
-liking. A simple way around this is to give a command like this:
-.DS
-ci $(SRCS) < /dev/tty
-.DE
-This would force the program's input to come from the terminal. If you
-can't do this for some reason, your only other alternative is to use
-PMake in its fullest compatibility mode. See
-.B Compatibility
-in chapter 4.
-.Ix 0 ref compatibility
-.LP
-.xH 2 Variables
-.LP
-PMake, like Make before it, has the ability to save text in variables
-to be recalled later at your convenience. Variables in PMake are used
-much like variables in the shell and, by tradition, consist of
-all upper-case letters (you don't
-.I have
-to use all upper-case letters.
-In fact there's nothing to stop you from calling a variable
-.CW @^&$%$ .
-Just tradition). Variables are assigned-to using lines of the form
-.Ix 0 def variable assignment
-.DS
-VARIABLE = value
-.DE
-.Ix 0 def variable assignment
-appended-to by
-.DS
-VARIABLE += value
-.DE
-.Ix 0 def variable appending
-.Ix 0 def variable assignment appended
-.Ix 0 def +=
-conditionally assigned-to (if the variable isn't already defined) by
-.DS
-VARIABLE ?= value
-.DE
-.Ix 0 def variable assignment conditional
-.Ix 0 def ?=
-and assigned-to with expansion (i.e. the value is expanded (see below)
-before being assigned to the variable\*-useful for placing a value at
-the beginning of a variable, or other things) by
-.DS
-VARIABLE := value
-.DE
-.Ix 0 def variable assignment expanded
-.Ix 0 def :=
-.LP
-Any whitespace before
-.I value
-is stripped off. When appending, a space is placed between the old
-value and the stuff being appended.
-.LP
-The final way a variable may be assigned to is using
-.DS
-VARIABLE != shell-command
-.DE
-.Ix 0 def variable assignment shell-output
-.Ix 0 def !=
-In this case,
-.I shell-command
-has all its variables expanded (see below) and is passed off to a
-shell to execute. The output of the shell is then placed in the
-variable. Any newlines (other than the final one) are replaced by
-spaces before the assignment is made. This is typically used to find
-the current directory via a line like:
-.DS
-CWD != pwd
-.DE
-.LP
-.B Note:
-this is intended to be used to execute commands that produce small amounts
-of output (e.g. ``pwd''). The implementation is less than intelligent and will
-likely freeze if you execute something that produces thousands of
-bytes of output (8 Kb is the limit on many UNIX systems).
-.LP
-The value of a variable may be retrieved by enclosing the variable
-name in parentheses or curly braces and preceding the whole thing
-with a dollar sign.
-.LP
-For example, to set the variable CFLAGS to the string
-.CW "\-I/sprite/src/lib/libc \-O" ,'' ``
-you would place a line
-.DS
-CFLAGS = \-I/sprite/src/lib/libc \-O
-.DE
-in the makefile and use the word
-.CW "$(CFLAGS)"
-wherever you would like the string
-.CW "\-I/sprite/src/lib/libc \-O"
-to appear. This is called variable expansion.
-.Ix 0 def variable expansion
-.No
-.LP
-Unlike Make, PMake will not expand a variable unless it knows
-the variable exists. E.g. if you have a
-.CW "${i}"
-in a shell command and you have not assigned a value to the variable
-.CW i
-(the empty string is considered a value, by the way), where Make would have
-substituted the empty string, PMake will leave the
-.CW "${i}"
-alone.
-To keep PMake from substituting for a variable it knows, precede the
-dollar sign with another dollar sign.
-(e.g. to pass
-.CW "${HOME}"
-to the shell, use
-.CW "$${HOME}" ).
-This causes PMake, in effect, to expand the
-.CW $
-macro, which expands to a single
-.CW $ .
-For compatibility, Make's style of variable expansion will be used
-if you invoke PMake with any of the compatibility flags (\c
-.B \-V ,
-.B \-B
-or
-.B \-M .
-The
-.B \-V
-flag alters just the variable expansion).
-.Ix 0 ref flags -V
-.Ix 0 ref flags -B
-.Ix 0 ref flags -M
-.Ix 0 ref compatibility
-.LP
-.Ix 0 ref variable expansion
-There are two different times at which variable expansion occurs:
-When parsing a dependency line, the expansion occurs immediately
-upon reading the line. If any variable used on a dependency line is
-undefined, PMake will print a message and exit.
-Variables in shell commands are expanded when the command is
-executed.
-Variables used inside another variable are expanded whenever the outer
-variable is expanded (the expansion of an inner variable has no effect
-on the outer variable. I.e. if the outer variable is used on a dependency
-line and in a shell command, and the inner variable changes value
-between when the dependency line is read and the shell command is
-executed, two different values will be substituted for the outer
-variable).
-.Ix 0 def variable types
-.LP
-Variables come in four flavors, though they are all expanded the same
-and all look about the same. They are (in order of expanding scope):
-.RS
-.IP \(bu 2
-Local variables.
-.Ix 0 ref variable local
-.IP \(bu 2
-Command-line variables.
-.Ix 0 ref variable command-line
-.IP \(bu 2
-Global variables.
-.Ix 0 ref variable global
-.IP \(bu 2
-Environment variables.
-.Ix 0 ref variable environment
-.RE
-.LP
-The classification of variables doesn't matter much, except that the
-classes are searched from the top (local) to the bottom (environment)
-when looking up a variable. The first one found wins.
-.xH 3 Local Variables
-.LP
-.Ix 0 def variable local
-Each target can have as many as seven local variables. These are
-variables that are only ``visible'' within that target's shell script
-and contain such things as the target's name, all of its sources (from
-all its dependency lines), those sources that were out-of-date, etc.
-Four local variables are defined for all targets. They are:
-.RS
-.IP ".TARGET"
-.Ix 0 def variable local .TARGET
-.Ix 0 def .TARGET
-The name of the target.
-.IP ".OODATE"
-.Ix 0 def variable local .OODATE
-.Ix 0 def .OODATE
-The list of the sources for the target that were considered out-of-date.
-The order in the list is not guaranteed to be the same as the order in
-which the dependencies were given.
-.IP ".ALLSRC"
-.Ix 0 def variable local .ALLSRC
-.Ix 0 def .ALLSRC
-The list of all sources for this target in the order in which they
-were given.
-.IP ".PREFIX"
-.Ix 0 def variable local .PREFIX
-.Ix 0 def .PREFIX
-The target without its suffix and without any leading path. E.g. for
-the target
-.CW ../../lib/compat/fsRead.c ,
-this variable would contain
-.CW fsRead .
-.RE
-.LP
-Three other local variables are set only for certain targets under
-special circumstances. These are the ``.IMPSRC,''
-.Ix 0 ref variable local .IMPSRC
-.Ix 0 ref .IMPSRC
-``.ARCHIVE,''
-.Ix 0 ref variable local .ARCHIVE
-.Ix 0 ref .ARCHIVE
-and ``.MEMBER''
-.Ix 0 ref variable local .MEMBER
-.Ix 0 ref .MEMBER
-variables. When they are set and how they are used is described later.
-.LP
-Four of these variables may be used in sources as well as in shell
-scripts.
-.Ix 0 def "dynamic source"
-.Ix 0 def source dynamic
-These are ``.TARGET'', ``.PREFIX'', ``.ARCHIVE'' and ``.MEMBER''. The
-variables in the sources are expanded once for each target on the
-dependency line, providing what is known as a ``dynamic source,''
-.Rd 0
-allowing you to specify several dependency lines at once. For example,
-.DS
-$(OBJS) : $(.PREFIX).c
-.DE
-will create a dependency between each object file and its
-corresponding C source file.
-.xH 3 Command-line Variables
-.LP
-.Ix 0 def variable command-line
-Command-line variables are set when PMake is first invoked by giving a
-variable assignment as one of the arguments. For example,
-.DS
-pmake "CFLAGS = -I/sprite/src/lib/libc -O"
-.DE
-would make
-.CW CFLAGS
-be a command-line variable with the given value. Any assignments to
-.CW CFLAGS
-in the makefile will have no effect, because once it
-is set, there is (almost) nothing you can do to change a command-line
-variable (the search order, you see). Command-line variables may be
-set using any of the four assignment operators, though only
-.CW =
-and
-.CW ?=
-behave as you would expect them to, mostly because assignments to
-command-line variables are performed before the makefile is read, thus
-the values set in the makefile are unavailable at the time.
-.CW +=
-.Ix 0 ref +=
-.Ix 0 ref variable assignment appended
-is the same as
-.CW = ,
-because the old value of the variable is sought only in the scope in
-which the assignment is taking place (for reasons of efficiency that I
-won't get into here).
-.CW :=
-and
-.CW ?=
-.Ix 0 ref :=
-.Ix 0 ref ?=
-.Ix 0 ref variable assignment expanded
-.Ix 0 ref variable assignment conditional
-will work if the only variables used are in the environment.
-.CW !=
-is sort of pointless to use from the command line, since the same
-effect can no doubt be accomplished using the shell's own command
-substitution mechanisms (backquotes and all that).
-.xH 3 Global Variables
-.LP
-.Ix 0 def variable global
-Global variables are those set or appended-to in the makefile.
-There are two classes of global variables: those you set and those PMake sets.
-As I said before, the ones you set can have any name you want them to have,
-except they may not contain a colon or an exclamation point.
-The variables PMake sets (almost) always begin with a
-period and always contain upper-case letters, only. The variables are
-as follows:
-.RS
-.IP .PMAKE
-.Ix 0 def variable global .PMAKE
-.Ix 0 def .PMAKE
-.Ix 0 def variable global MAKE
-.Ix 0 def MAKE
-The name by which PMake was invoked is stored in this variable. For
-compatibility, the name is also stored in the MAKE variable.
-.IP .MAKEFLAGS
-.Ix 0 def variable global .MAKEFLAGS
-.Ix 0 def .MAKEFLAGS variable
-.Ix 0 def variable global MFLAGS
-.Ix 0 def MFLAGS
-All the relevant flags with which PMake was invoked. This does not
-include such things as
-.B \-f
-or variable assignments. Again for compatibility, this value is stored
-in the MFLAGS variable as well.
-.RE
-.LP
-Two other variables, ``.INCLUDES'' and ``.LIBS,'' are covered in the
-section on special targets in chapter 3.
-.Ix 0 ref variable global .INCLUDES
-.Ix 0 ref variable global .LIBS
-.LP
-Global variables may be deleted using lines of the form:
-.Ix 0 def #undef
-.Ix 0 def variable deletion
-.DS
-#undef \fIvariable\fP
-.DE
-The
-.CW # ' `
-must be the first character on the line. Note that this may only be
-done on global variables.
-.xH 3 Environment Variables
-.LP
-.Ix 0 def variable environment
-Environment variables are passed by the shell that invoked PMake and
-are given by PMake to each shell it invokes. They are expanded like
-any other variable, but they cannot be altered in any way.
-.LP
-One special environment variable,
-.CW PMAKE ,
-.Ix 0 def variable environment PMAKE
-is examined by PMake for command-line flags, variable assignments,
-etc., it should always use. This variable is examined before the
-actual arguments to PMake are. In addition, all flags given to PMake,
-either through the
-.CW PMAKE
-variable or on the command line, are placed in this environment
-variable and exported to each shell PMake executes. Thus recursive
-invocations of PMake automatically receive the same flags as the
-top-most one.
-.LP
-Using all these variables, you can compress the sample makefile even more:
-.DS
-OBJS = a.o b.o c.o
-program : $(OBJS)
- cc $(.ALLSRC) \-o $(.TARGET)
-$(OBJS) : defs.h
-a.o : a.c
- cc \-c a.c
-b.o : b.c
- cc \-c b.c
-c.o : c.c
- cc \-c c.c
-.DE
-.Ix 0 ref variable local .ALLSRC
-.Ix 0 ref .ALLSRC
-.Ix 0 ref variable local .TARGET
-.Ix 0 ref .TARGET
-.Rd 3
-.xH 2 Comments
-.LP
-.Ix 0 def comments
-Comments in a makefile start with a `#' character and extend to the
-end of the line. They may appear
-anywhere you want them, except in a shell command (though the shell
-will treat it as a comment, too). If, for some reason, you need to use the `#'
-in a variable or on a dependency line, put a backslash in front of it.
-PMake will compress the two into a single `#' (Note: this isn't true
-if PMake is operating in full-compatibility mode).
-.Ix 0 ref flags -M
-.Ix 0 ref compatibility
-.xH 2 Parallelism
-.No
-.LP
-PMake was specifically designed to re-create several targets at once,
-when possible. You do not have to do anything special to cause this to
-happen (unless PMake was configured to not act in parallel, in which
-case you will have to make use of the
-.B \-L
-and
-.B \-J
-flags (see below)),
-.Ix 0 ref flags -L
-.Ix 0 ref flags -J
-but you do have to be careful at times.
-.LP
-There are several problems you are likely to encounter. One is
-that some makefiles (and programs) are written in such a way that it is
-impossible for two targets to be made at once. The program
-.CW xstr ,
-for example,
-always modifies the files
-.CW strings
-and
-.CW x.c .
-There is no way to change it. Thus you cannot run two of them at once
-without something being trashed. Similarly, if you have commands
-in the makefile that always send output to the same file, you will not
-be able to make more than one target at once unless you change the
-file you use. You can, for instance, add a
-.CW $$$$
-to the end of the file name to tack on the process ID of the shell
-executing the command (each
-.CW $$
-expands to a single
-.CW $ ,
-thus giving you the shell variable
-.CW $$ ).
-Since only one shell is used for all the
-commands, you'll get the same file name for each command in the
-script.
-.LP
-The other problem comes from improperly-specified dependencies that
-worked in Make because of its sequential, depth-first way of examining
-them. While I don't want to go into depth on how PMake
-works (look in chapter 4 if you're interested), I will warn you that
-files in two different ``levels'' of the dependency tree may be
-examined in a different order in PMake than they were in Make. For
-example, given the makefile
-.DS
-a : b c
-b : d
-.DE
-PMake will examine the targets in the order
-.CW c ,
-.CW d ,
-.CW b ,
-.CW a .
-If the makefile's author expected PMake to abort before making
-.CW c
-if an error occurred while making
-.CW b ,
-or if
-.CW b
-needed to exist before
-.CW c
-was made,
-s/he will be sorely disappointed. The dependencies are
-incomplete, since in both these cases,
-.CW c
-would depend on
-.CW b .
-So watch out.
-.LP
-Another problem you may face is that, while PMake is set up to handle the
-output from multiple jobs in a graceful fashion, the same is not so for input.
-It has no way to regulate input to different jobs,
-so if you use the redirection from
-.CW /dev/tty
-I mentioned earlier, you must be careful not to run two of the jobs at once.
-.xH 2 Writing and Debugging a Makefile
-.LP
-Now you know most of what's in a makefile, what do you do next? There
-are two choices: (1) use one of the uncommonly-available makefile
-generators or (2) write your own makefile (I leave out the third choice of
-ignoring PMake and doing everything by hand as being beyond the bounds
-of common sense).
-.LP
-When faced with the writing of a makefile, it is usually best to start
-from first principles: just what
-.I are
-you trying to do? What do you want the makefile finally to produce?
-.LP
-To begin with a somewhat traditional example, let's say you need to
-write a makefile to create a program,
-.CW expr ,
-that takes standard infix expressions and converts them to prefix form (for
-no readily apparent reason). You've got three source files, in C, that
-make up the program:
-.CW main.c ,
-.CW parse.c ,
-and
-.CW output.c .
-Harking back to my pithy advice about dependency lines, you write the
-first line of the file:
-.DS
-expr : main.o parse.o output.o
-.DE
-because you remember
-.CW expr
-is made from
-.CW .o
-files, not
-.CW .c
-files. Similarly for the
-.CW .o
-files you produce the lines:
-.DS
-main.o : main.c
-parse.o : parse.c
-output.o : output.c
-main.o parse.o output.o : defs.h
-.DE
-.LP
-Great. You've now got the dependencies specified. What you need now is
-commands. These commands, remember, must produce the target on the
-dependency line, usually by using the sources you've listed.
-You remember about local variables? Good, so it should come
-to you as no surprise when you write
-.DS
-expr : main.o parse.o output.o
- cc -o $(.TARGET) $(.ALLSRC)
-.DE
-Why use the variables? If your program grows to produce postfix
-expressions too (which, of course, requires a name change or two), it
-is one fewer place you have to change the file. You cannot do this for
-the object files, however, because they depend on their corresponding
-source files
-.I and
-.CW defs.h ,
-thus if you said
-.DS
- cc -c $(.ALLSRC)
-.DE
-you'd get (for
-.CW main.o ):
-.DS
- cc -c main.c defs.h
-.DE
-which is wrong. So you round out the makefile with these lines:
-.DS
-main.o : main.c
- cc -c main.c
-parse.o : parse.c
- cc -c parse.c
-output.o : output.c
- cc -c output.c
-.DE
-.LP
-The makefile is now complete and will, in fact, create the program you
-want it to without unnecessary compilations or excessive typing on
-your part. There are two things wrong with it, however (aside from it
-being altogether too long, something I'll address in chapter 3):
-.IP 1)
-The string
-.CW "main.o parse.o output.o" '' ``
-is repeated twice, necessitating two changes when you add postfix
-(you were planning on that, weren't you?). This is in direct violation
-of de Boor's First Rule of writing makefiles:
-.QP
-.I
-Anything that needs to be written more than once
-should be placed in a variable.
-.IP "\&"
-I cannot emphasize this enough as being very important to the
-maintenance of a makefile and its program.
-.IP 2)
-There is no way to alter the way compilations are performed short of
-editing the makefile and making the change in all places. This is evil
-and violates de Boor's Second Rule, which follows directly from the
-first:
-.QP
-.I
-Any flags or programs used inside a makefile should be placed in a variable so
-they may be changed, temporarily or permanently, with the greatest ease.
-.LP
-The makefile should more properly read:
-.DS
-OBJS = main.o parse.o output.o
-expr : $(OBJS)
- $(CC) $(CFLAGS) -o $(.TARGET) $(.ALLSRC)
-main.o : main.c
- $(CC) $(CFLAGS) -c main.c
-parse.o : parse.c
- $(CC) $(CFLAGS) -c parse.c
-output.o : output.c
- $(CC) $(CFLAGS) -c output.c
-$(OBJS) : defs.h
-.DE
-Alternatively, if you like the idea of dynamic sources mentioned in
-section 2.3.1,
-.Rm 0 2.3.1
-.Rd 4
-.Ix 0 ref "dynamic source"
-.Ix 0 ref source dynamic
-you could write it like this:
-.DS
-OBJS = main.o parse.o output.o
-expr : $(OBJS)
- $(CC) $(CFLAGS) -o $(.TARGET) $(.ALLSRC)
-$(OBJS) : $(.PREFIX).c defs.h
- $(CC) $(CFLAGS) -c $(.PREFIX).c
-.DE
-These two rules and examples lead to de Boor's First Corollary:
-.QP
-.I
-Variables are your friends.
-.LP
-Once you've written the makefile comes the sometimes-difficult task of
-.Ix 0 ref debugging
-making sure the darn thing works. Your most helpful tool to make sure
-the makefile is at least syntactically correct is the
-.B \-n
-.Ix 0 ref flags -n
-flag, which allows you to see if PMake will choke on the makefile. The
-second thing the
-.B \-n
-flag lets you do is see what PMake would do without it actually doing
-it, thus you can make sure the right commands would be executed were
-you to give PMake its head.
-.LP
-When you find your makefile isn't behaving as you hoped, the first
-question that comes to mind (after ``What time is it, anyway?'') is
-``Why not?'' In answering this, two flags will serve you well:
-.CW "-d m" '' ``
-.Ix 0 ref flags -d
-and
-.CW "-p 2" .'' ``
-.Ix 0 ref flags -p
-The first causes PMake to tell you as it examines each target in the
-makefile and indicate why it is deciding whatever it is deciding. You
-can then use the information printed for other targets to see where
-you went wrong. The
-.CW "-p 2" '' ``
-flag makes PMake print out its internal state when it is done,
-allowing you to see that you forgot to make that one chapter depend on
-that file of macros you just got a new version of. The output from
-.CW "-p 2" '' ``
-is intended to resemble closely a real makefile, but with additional
-information provided and with variables expanded in those commands
-PMake actually printed or executed.
-.LP
-Something to be especially careful about is circular dependencies.
-.Ix 0 def dependency circular
-E.g.
-.DS
-a : b
-b : c d
-d : a
-.DE
-In this case, because of how PMake works,
-.CW c
-is the only thing PMake will examine, because
-.CW d
-and
-.CW a
-will effectively fall off the edge of the universe, making it
-impossible to examine

-(or them, for that matter).
-PMake will tell you (if run in its normal mode) all the targets
-involved in any cycle it looked at (i.e. if you have two cycles in the
-graph (naughty, naughty), but only try to make a target in one of
-them, PMake will only tell you about that one. You'll have to try to
-make the other to find the second cycle). When run as Make, it will
-only print the first target in the cycle.
-.xH 2 Invoking PMake
-.LP
-.Ix 0 ref flags
-.Ix 0 ref arguments
-.Ix 0 ref usage
-PMake comes with a wide variety of flags to choose from.
-They may appear in any order, interspersed with command-line variable
-assignments and targets to create.
-The flags are as follows:
-.IP "\fB\-d\fP \fIwhat\fP"
-.Ix 0 def flags -d
-.Ix 0 ref debugging
-This causes PMake to spew out debugging information that
-may prove useful to you. If you can't
-figure out why PMake is doing what it's doing, you might try using
-this flag. The
-.I what
-parameter is a string of single characters that tell PMake what
-aspects you are interested in. Most of what I describe will make
-little sense to you, unless you've dealt with Make before. Just
-remember where this table is and come back to it as you read on.
-The characters and the information they produce are as follows:
-.RS
-.IP a
-Archive searching and caching.
-.IP c
-Conditional evaluation.
-.IP d
-The searching and caching of directories.
-.IP j
-Various snippets of information related to the running of the multiple
-shells. Not particularly interesting.
-.IP m
-The making of each target: what target is being examined; when it was
-last modified; whether it is out-of-date; etc.
-.IP p
-Makefile parsing.
-.IP r
-Remote execution.
-.IP s
-The application of suffix-transformation rules. (See chapter 3)
-.IP t
-The maintenance of the list of targets.
-.IP v
-Variable assignment.
-.RE
-.IP "\&"
-Of these all, the
-.CW m
-and
-.CW s
-letters will be most useful to you.
-If the
-.B \-d
-is the final argument or the argument from which it would get these
-key letters (see below for a note about which argument would be used)
-begins with a
-.B \- ,
-all of these debugging flags will be set, resulting in massive amounts
-of output.
-.IP "\fB\-f\fP \fImakefile\fP"
-.Ix 0 def flags -f
-Specify a makefile to read different from the standard makefiles
-.CW Makefile "\&" (
-or
-.CW makefile ).
-.Ix 0 ref makefile default
-.Ix 0 ref makefile other
-If
-.I makefile
-is ``\-'', PMake uses the standard input. This is useful for making
-quick and dirty makefiles.\|.\|.
-.Ix 0 ref makefile "quick and dirty"
-.IP \fB\-h\fP
-.Ix 0 def flags -h
-Prints out a summary of the various flags PMake accepts. It can also
-be used to find out what level of concurrency was compiled into the
-version of PMake you are using (look at
-.B \-J
-and
-.B \-L )
-and various other information on how PMake was configured.
-.Ix 0 ref configuration
-.Ix 0 ref makefile system
-.IP \fB\-i\fP
-.Ix 0 def flags -i
-If you give this flag, PMake will ignore non-zero status returned
-by any of its shells. It's like placing a `\-' before all the commands
-in the makefile.
-.IP \fB\-k\fP
-.Ix 0 def flags -k
-This is similar to
-.B \-i
-in that it allows PMake to continue when it sees an error, but unlike
-.B \-i ,
-where PMake continues blithely as if nothing went wrong,
-.B \-k
-causes it to recognize the error and only continue work on those
-things that don't depend on the target, either directly or indirectly (through
-depending on something that depends on it), whose creation returned the error.
-The `k' is for ``keep going''.\|.\|.
-.Ix 0 ref target
-.IP \fB\-l\fP
-.Ix 0 def flags -l
-PMake has the ability to lock a directory against other
-people executing it in the same directory (by means of a file called
-``LOCK.make'' that it creates and checks for in the directory). This
-is a Good Thing because two people doing the same thing in the same place
-can be disastrous for the final product (too many cooks and all that).
-Whether this locking is the default is up to your system
-administrator. If locking is on,
-.B \-l
-will turn it off, and vice versa. Note that this locking will not
-prevent \fIyou\fP from invoking PMake twice in the same place \*- if
-you own the lock file, PMake will warn you about it but continue to execute.
-.IP "\fB\-m\fP \fIdirectory\fP"
-.Ix 0 def flags -m
-Tells PMake another place to search for included makefiles via the <...>
-style. Several
-.B \-m
-options can be given to form a search path. If this construct is used the
-default system makefile search path is completely overridden.
-To be explained in chapter 3, section 3.2.
-.Rm 2 3.2
-.IP \fB\-n\fP
-.Ix 0 def flags -n
-This flag tells PMake not to execute the commands needed to update the
-out-of-date targets in the makefile. Rather, PMake will simply print
-the commands it would have executed and exit. This is particularly
-useful for checking the correctness of a makefile. If PMake doesn't do
-what you expect it to, it's a good chance the makefile is wrong.
-.IP "\fB\-p\fP \fInumber\fP"
-.Ix 0 def flags -p
-.Ix 0 ref debugging
-This causes PMake to print its input in a reasonable form, though
-not necessarily one that would make immediate sense to anyone but me. The
-.I number
-is a bitwise-or of 1 and 2 where 1 means it should print the input
-before doing any processing and 2 says it should print it after
-everything has been re-created. Thus
-.CW "\-p 3"
-would print it twice\*-once before processing and once after (you
-might find the difference between the two interesting). This is mostly
-useful to me, but you may find it informative in some bizarre circumstances.
-.IP \fB\-q\fP
-.Ix 0 def flags -q
-If you give PMake this flag, it will not try to re-create anything. It
-will just see if anything is out-of-date and exit non-zero if so.
-.IP \fB\-r\fP
-.Ix 0 def flags -r
-When PMake starts up, it reads a default makefile that tells it what
-sort of system it's on and gives it some idea of what to do if you
-don't tell it anything. I'll tell you about it in chapter 3. If you
-give this flag, PMake won't read the default makefile.
-.IP \fB\-s\fP
-.Ix 0 def flags -s
-This causes PMake to not print commands before they're executed. It
-is the equivalent of putting an `@' before every command in the
-makefile.
-.IP \fB\-t\fP
-.Ix 0 def flags -t
-Rather than try to re-create a target, PMake will simply ``touch'' it
-so as to make it appear up-to-date. If the target didn't exist before,
-it will when PMake finishes, but if the target did exist, it will
-appear to have been updated.
-.IP \fB\-v\fP
-.Ix 0 def flags -v
-This is a mixed-compatibility flag intended to mimic the System V
-version of Make. It is the same as giving
-.B \-B ,
-and
-.B \-V
-as well as turning off directory locking. Targets can still be created
-in parallel, however. This is the mode PMake will enter if it is
-invoked either as
-.CW smake '' ``
-or
-.CW vmake ''. ``
-.IP \fB\-x\fP
-.Ix 0 def flags -x
-This tells PMake it's ok to export jobs to other machines, if they're
-available. It is used when running in Make mode, as exporting in this
-mode tends to make things run slower than if the commands were just
-executed locally.
-.IP \fB\-B\fP
-.Ix 0 ref compatibility
-.Ix 0 def flags -B
-Forces PMake to be as backwards-compatible with Make as possible while
-still being itself.
-This includes:

-one is not available when it is started.
-.IP \fB\-M\fP
-.Ix 0 ref compatibility
-.Ix 0 def flags -M
-This is the flag that provides absolute, complete, full compatibility

-PMake, but it is non-parallel. This is the mode PMake enters if you
-call it
-.CW make .'' ``
-.IP \fB\-P\fP
-.Ix 0 def flags -P
-.Ix 0 ref "output control"
-When creating targets in parallel, several shells are executing at
-once, each wanting to write its own two cent's-worth to the screen.
-This output must be captured by PMake in some way in order to prevent
-the screen from being filled with garbage even more indecipherable
-than you usually see. PMake has two ways of doing this, one of which
-provides for much cleaner output and a clear separation between the
-output of different jobs, the other of which provides a more immediate
-response so one can tell what is really happening. The former is done
-by notifying you when the creation of a target starts, capturing the
-output and transferring it to the screen all at once when the job
-finishes. The latter is done by catching the output of the shell (and
-its children) and buffering it until an entire line is received, then
-printing that line preceded by an indication of which job produced
-the output. Since I prefer this second method, it is the one used by
-default. The first method will be used if you give the
-.B \-P
-flag to PMake.
-.IP \fB\-V\fP
-.Ix 0 def flags -V
-As mentioned before, the

-There are several times when PMake will print a message at you that is
-only a warning, i.e. it can continue to work in spite of your having
-done something silly (such as forgotten a leading tab for a shell
-command). Sometimes you are well aware of silly things you have done
-and would like PMake to stop bothering you. This flag tells it to shut
-up about anything non-fatal.
-.IP \fB\-X\fP
-.Ix 0 def flags -X
-This flag causes PMake to not attempt to export any jobs to another
-machine.
-.LP
-Several flags may follow a single `\-'. Those flags that require
-arguments take them from successive parameters. E.g.
-.DS
-pmake -fDnI server.mk DEBUG /chip2/X/server/include
-.DE
-will cause PMake to read
-.CW server.mk
-as the input makefile, define the variable
-.CW DEBUG
-as a global variable and look for included makefiles in the directory
-.CW /chip2/X/server/include .
-.xH 2 Summary
-.LP
-A makefile is made of four types of lines:

-.IP \(bu 2
-Comments, include statements and conditional directives
-.RE
-.LP
-A dependency line is a list of one or more targets, an operator
-.CW : ', (`
-.CW :: ', `
-or
-.CW ! '), `
-and a list of zero or more sources. Sources may contain wildcards and
-certain local variables.
-.LP
-A creation command is a regular shell command preceded by a tab. In
-addition, if the first two characters after the tab (and other
-whitespace) are a combination of
-.CW @ ' `
-or
-.CW - ', `
-PMake will cause the command to not be printed (if the character is
-.CW @ ') `
-or errors from it to be ignored (if
-.CW - '). `
-A blank line, dependency line or variable assignment terminates a
-creation script. There may be only one creation script for each target
-with a
-.CW : ' `
-or
-.CW ! ' `
-operator.
-.LP
-Variables are places to store text. They may be unconditionally
-assigned-to using the
-.CW = ' `
-.Ix 0 ref =
-.Ix 0 ref variable assignment
-operator, appended-to using the

-.Ix 0 ref ?=
-.Ix 0 ref variable assignment conditional
-operator, and assigned-to with variable expansion with the
-.CW := ' `
-.Ix 0 ref :=
-.Ix 0 ref variable assignment expanded
-operator. The output of a shell command may be assigned to a variable
-using the
-.CW != ' `
-.Ix 0 ref !=
-.Ix 0 ref variable assignment shell-output
-operator. Variables may be expanded (their value inserted) by enclosing
-their name in parentheses or curly braces, preceded by a dollar sign.
-A dollar sign may be escaped with another dollar sign. Variables are
-not expanded if PMake doesn't know about them. There are seven local
-variables:
-.CW .TARGET ,
-.CW .ALLSRC ,
-.CW .OODATE ,
-.CW .PREFIX ,
-.CW .IMPSRC ,
-.CW .ARCHIVE ,
-and
-.CW .MEMBER .
-Four of them

-.xH 1 Short-cuts and Other Nice Things
-.LP
-Based on what I've told you so far, you may have gotten the impression
-that PMake is just a way of storing away commands and making sure you
-don't forget to compile something. Good. That's just what it is.
-However, the ways I've described have been inelegant, at best, and
-painful, at worst.
-This chapter contains things that make the
-writing of makefiles easier and the makefiles themselves shorter and
-easier to modify (and, occasionally, simpler). In this chapter, I
-assume you are somewhat more
-familiar with Sprite (or UNIX, if that's what you're using) than I did
-in chapter 2, just so you're on your toes.
-So without further ado...
-.xH 2 Transformation Rules
-.LP
-As you know, a file's name consists of two parts: a base name, which
-gives some hint as to the contents of the file, and a suffix, which
-usually indicates the format of the file.
-Over the years, as
-.UX
-has developed,
-naming conventions, with regard to suffixes, have also developed that have
-become almost as incontrovertible as Law. E.g. a file ending in
-.CW .c
-is assumed to contain C source code; one with a
-.CW .o
-suffix is assumed to be a compiled, relocatable object file that may
-be linked into any program; a file with a
-.CW .ms
-suffix is usually a text file to be processed by Troff with the \-ms
-macro package, and so on.
-One of the best aspects of both Make and PMake comes from their
-understanding of how the suffix of a file pertains to its contents and
-their ability to do things with a file based solely on its suffix. This
-ability comes from something known as a transformation rule. A
-transformation rule specifies how to change a file with one suffix
-into a file with another suffix.
-.LP
-A transformation rule looks much like a dependency line, except the
-target is made of two known suffixes stuck together. Suffixes are made
-known to PMake by placing them as sources on a dependency line whose
-target is the special target
-.CW .SUFFIXES .
-E.g.
-.DS
-\&.SUFFIXES : .o .c
-\&.c.o :
- $(CC) $(CFLAGS) -c $(.IMPSRC)
-.DE
-The creation script attached to the target is used to transform a file with
-the first suffix (in this case,
-.CW .c )
-into a file with the second suffix (here,
-.CW .o ).
-In addition, the target inherits whatever attributes have been applied
-to the transformation rule.
-The simple rule given above says that to transform a C source file
-into an object file, you compile it using
-.CW cc
-with the
-.CW \-c
-flag.
-This rule is taken straight from the system makefile. Many
-transformation rules (and suffixes) are defined there, and I refer you
-to it for more examples (type
-.CW "pmake -h" '' ``
-to find out where it is).
-.LP
-There are several things to note about the transformation rule given
-above:
-.RS
-.IP 1)
-The
-.CW .IMPSRC
-variable.
-.Ix 0 def variable local .IMPSRC
-.Ix 0 def .IMPSRC
-This variable is set to the ``implied source'' (the file from which
-the target is being created; the one with the first suffix), which, in this
-case, is the .c file.
-.IP 2)
-The
-.CW CFLAGS
-variable. Almost all of the transformation rules in the system
-makefile are set up using variables that you can alter in your
-makefile to tailor the rule to your needs. In this case, if you want
-all your C files to be compiled with the
-.B \-g
-flag, to provide information for
-.CW dbx ,
-you would set the
-.CW CFLAGS
-variable to contain
-.CW -g
-.CW "CFLAGS = -g" '') (``
-and PMake would take care of the rest.
-.RE
-.LP
-To give you a quick example, the makefile in 2.3.4
-.Rm 3 2.3.4
-could be changed to this:
-.DS
-OBJS = a.o b.o c.o
-program : $(OBJS)
- $(CC) -o $(.TARGET) $(.ALLSRC)
-$(OBJS) : defs.h
-.DE
-The transformation rule I gave above takes the place of the 6 lines\**
-.FS
-This is also somewhat cleaner, I think, than the dynamic source
-solution presented in 2.6
-.FE
-.Rm 4 2.6
-.DS
-a.o : a.c
- cc -c a.c
-b.o : b.c
- cc -c b.c
-c.o : c.c
- cc -c c.c
-.DE
-.LP
-Now you may be wondering about the dependency between the
-.CW .o
-and
-.CW .c
-files \*- it's not mentioned anywhere in the new makefile. This is
-because it isn't needed: one of the effects of applying a
-transformation rule is the target comes to depend on the implied
-source. That's why it's called the implied
-.I source .
-.LP
-For a more detailed example. Say you have a makefile like this:
-.DS
-a.out : a.o b.o
- $(CC) $(.ALLSRC)
-.DE
-and a directory set up like this:
-.DS
-total 4
--rw-rw-r-- 1 deboor 34 Sep 7 00:43 Makefile
--rw-rw-r-- 1 deboor 119 Oct 3 19:39 a.c

--rw-rw-r-- 1 deboor 69 Sep 7 00:43 b.c
-.DE
-While just typing
-.CW pmake '' ``
-will do the right thing, it's much more informative to type
-.CW "pmake -d s" ''. ``
-This will show you what PMake is up to as it processes the files. In
-this case, PMake prints the following:
-.DS
-Suff_FindDeps (a.out)
- using existing source a.o
- applying .o -> .out to "a.o"
-Suff_FindDeps (a.o)

-.DE
-.LP
-.CW Suff_FindDeps
-is the name of a function in PMake that is called to check for implied
-sources for a target using transformation rules.
-The transformations it tries are, naturally
-enough, limited to the ones that have been defined (a transformation
-may be defined multiple times, by the way, but only the most recent
-one will be used). You will notice, however, that there is a definite
-order to the suffixes that are tried. This order is set by the
-relative positions of the suffixes on the
-.CW .SUFFIXES
-line \*- the earlier a suffix appears, the earlier it is checked as
-the source of a transformation. Once a suffix has been defined, the
-only way to change its position in the pecking order is to remove all
-the suffixes (by having a
-.CW .SUFFIXES
-dependency line with no sources) and redefine them in the order you
-want. (Previously-defined transformation rules will be automatically
-redefined as the suffixes they involve are re-entered.)
-.LP
-Another way to affect the search order is to make the dependency
-explicit. In the above example,
-.CW a.out
-depends on
-.CW a.o
-and
-.CW b.o .
-Since a transformation exists from
-.CW .o
-to
-.CW .out ,
-PMake uses that, as indicated by the
-.CW "using existing source a.o" '' ``
-message.
-.LP
-The search for a transformation starts from the suffix of the target
-and continues through all the defined transformations, in the order
-dictated by the suffix ranking, until an existing file with the same
-base (the target name minus the suffix and any leading directories) is
-found. At that point, one or more transformation rules will have been
-found to change the one existing file into the target.
-.LP
-For example, ignoring what's in the system makefile for now, say you
-have a makefile like this:
-.DS
-\&.SUFFIXES : .out .o .c .y .l
-\&.l.c :
- lex $(.IMPSRC)
- mv lex.yy.c $(.TARGET)
-\&.y.c :
- yacc $(.IMPSRC)
- mv y.tab.c $(.TARGET)
-\&.c.o :
- cc -c $(.IMPSRC)
-\&.o.out :
- cc -o $(.TARGET) $(.IMPSRC)
-.DE
-and the single file
-.CW jive.l .
-If you were to type
-.CW "pmake -rd ms jive.out" ,'' ``
-you would get the following output for
-.CW jive.out :
-.DS
-Suff_FindDeps (jive.out)
- trying jive.o...not there
- trying jive.c...not there
- trying jive.y...not there
- trying jive.l...got it
- applying .l -> .c to "jive.l"
- applying .c -> .o to "jive.c"
- applying .o -> .out to "jive.o"
-.DE
-and this is why: PMake starts with the target
-.CW jive.out ,
-figures out its suffix
-.CW .out ) (
-and looks for things it can transform to a
-.CW .out
-file. In this case, it only finds
-.CW .o ,
-so it looks for the file
-.CW jive.o .
-It fails to find it, so it looks for transformations into a
-.CW .o
-file. Again it has only one choice:
-.CW .c .
-So it looks for
-.CW jive.c
-and, as you know, fails to find it. At this point it has two choices:
-it can create the
-.CW .c
-file from either a
-.CW .y
-file or a
-.CW .l
-file. Since
-.CW .y
-came first on the
-.CW .SUFFIXES
-line, it checks for
-.CW jive.y
-first, but can't find it, so it looks for
-.CW jive.l
-and, lo and behold, there it is.
-At this point, it has defined a transformation path as follows:
-.CW .l
-\(->
-.CW .c
-\(->
-.CW .o
-\(->
-.CW .out
-and applies the transformation rules accordingly. For completeness,
-and to give you a better idea of what PMake actually did with this
-three-step transformation, this is what PMake printed for the rest of
-the process:
-.DS
-Suff_FindDeps (jive.o)
- using existing source jive.c
- applying .c -> .o to "jive.c"

-One final question remains: what does PMake do with targets that have
-no known suffix? PMake simply pretends it actually has a known suffix
-and searches for transformations accordingly.
-The suffix it chooses is the source for the
-.CW .NULL
-.Ix 0 ref .NULL
-target mentioned later. In the system makefile,
-.CW .out
-is chosen as the ``null suffix''
-.Ix 0 def suffix null
-.Ix 0 def "null suffix"
-because most people use PMake to create programs. You are, however,
-free and welcome to change it to a suffix of your own choosing.
-The null suffix is ignored, however, when PMake is in compatibility
-mode (see chapter 4).
-.xH 2 Including Other Makefiles
-.Ix 0 def makefile inclusion
-.Rd 2
-.LP
-Just as for programs, it is often useful to extract certain parts of a
-makefile into another file and just include it in other makefiles
-somehow. Many compilers allow you say something like
-.DS
-#include "defs.h"
-.DE
-to include the contents of
-.CW defs.h
-in the source file. PMake allows you to do the same thing for
-makefiles, with the added ability to use variables in the filenames.
-An include directive in a makefile looks either like this:
-.DS
-#include <file>
-.DE
-or this
-.DS
-#include "file"
-.DE
-The difference between the two is where PMake searches for the file:
-the first way, PMake will look for
-the file only in the system makefile directory (or directories)
-(to find out what that directory is, give PMake the
-.B \-h
-flag).
-.Ix 0 ref flags -h
-The system makefile directory search path can be overridden via the
-.B \-m
-option.
-.Ix 0 ref flags -m
-For files in double-quotes, the search is more complex:
-.RS
-.IP 1)
-The directory of the makefile that's including the file.
-.IP 2)
-The current directory (the one in which you invoked PMake).
-.IP 3)
-The directories given by you using
-.B \-I
-flags, in the order in which you gave them.
-.IP 4)
-Directories given by
-.CW .PATH
-dependency lines (see chapter 4).
-.IP 5)
-The system makefile directory.
-.RE
-.LP
-in that order.
-.LP
-You are free to use PMake variables in the filename\*-PMake will
-expand them before searching for the file. You must specify the
-searching method with either angle brackets or double-quotes
-.I outside
-of a variable expansion. I.e. the following
-.DS
-SYSTEM = <command.mk>
-
-#include $(SYSTEM)
-.DE
-won't work.
-.xH 2 Saving Commands
-.LP
-.Ix 0 def ...
-There may come a time when you will want to save certain commands to
-be executed when everything else is done. For instance: you're
-making several different libraries at one time and you want to create the
-members in parallel. Problem is,
-.CW ranlib
-is another one of those programs that can't be run more than once in
-the same directory at the same time (each one creates a file called
-.CW __.SYMDEF
-into which it stuffs information for the linker to use. Two of them
-running at once will overwrite each other's file and the result will
-be garbage for both parties). You might want a way to save the ranlib
-commands til the end so they can be run one after the other, thus
-keeping them from trashing each other's file. PMake allows you to do
-this by inserting an ellipsis (``.\|.\|.'') as a command between
-commands to be run at once and those to be run later.
-.LP
-So for the
-.CW ranlib
-case above, you might do this:
-.Rd 5
-.DS
-lib1.a : $(LIB1OBJS)
- rm -f $(.TARGET)
- ar cr $(.TARGET) $(.ALLSRC)
- ...
- ranlib $(.TARGET)
-
-lib2.a : $(LIB2OBJS)
- rm -f $(.TARGET)
- ar cr $(.TARGET) $(.ALLSRC)
- ...
- ranlib $(.TARGET)
-.DE
-.Ix 0 ref variable local .TARGET
-.Ix 0 ref variable local .ALLSRC
-This would save both
-.DS
-ranlib $(.TARGET)
-.DE
-commands until the end, when they would run one after the other
-(using the correct value for the
-.CW .TARGET
-variable, of course).
-.LP
-Commands saved in this manner are only executed if PMake manages to
-re-create everything without an error.
-.xH 2 Target Attributes
-.LP
-PMake allows you to give attributes to targets by means of special
-sources. Like everything else PMake uses, these sources begin with a
-period and are made up of all upper-case letters. There are various
-reasons for using them, and I will try to give examples for most of
-them. Others you'll have to find uses for yourself. Think of it as ``an
-exercise for the reader.'' By placing one (or more) of these as a source on a
-dependency line, you are ``marking the target(s) with that
-attribute.'' That's just the way I phrase it, so you know.
-.LP
-Any attributes given as sources for a transformation rule are applied
-to the target of the transformation rule when the rule is applied.
-.Ix 0 def attributes
-.Ix 0 ref source
-.Ix 0 ref target
-.nr pw 12
-.IP .DONTCARE \n(pw
-.Ix 0 def attributes .DONTCARE
-.Ix 0 def .DONTCARE
-If a target is marked with this attribute and PMake can't figure out
-how to create it, it will ignore this fact and assume the file isn't
-really needed or actually exists and PMake just can't find it. This may prove
-wrong, but the error will be noted later on, not when PMake tries to create
-the target so marked. This attribute also prevents PMake from
-attempting to touch the target if it is given the
-.B \-t
-flag.
-.Ix 0 ref flags -t
-.IP .EXEC \n(pw
-.Ix 0 def attributes .EXEC
-.Ix 0 def .EXEC
-This attribute causes its shell script to be executed while having no
-effect on targets that depend on it. This makes the target into a sort
-of subroutine. An example. Say you have some LISP files that need to
-be compiled and loaded into a LISP process. To do this, you echo LISP
-commands into a file and execute a LISP with this file as its input
-when everything's done. Say also that you have to load other files
-from another system before you can compile your files and further,
-that you don't want to go through the loading and dumping unless one
-of
-.I your
-files has changed. Your makefile might look a little bit
-like this (remember, this is an educational example, and don't worry
-about the
-.CW COMPILE
-rule, all will soon become clear, grasshopper):
-.DS
-system : init a.fasl b.fasl c.fasl
- for i in $(.ALLSRC);
- do
- echo -n '(load "' >> input
- echo -n ${i} >> input
- echo '")' >> input
- done
- echo '(dump "$(.TARGET)")' >> input
- lisp < input
-
-a.fasl : a.l init COMPILE
-b.fasl : b.l init COMPILE
-c.fasl : c.l init COMPILE
-COMPILE : .USE
- echo '(compile "$(.ALLSRC)")' >> input
-init : .EXEC
- echo '(load-system)' > input
-.DE
-.Ix 0 ref .USE
-.Ix 0 ref attributes .USE
-.Ix 0 ref variable local .ALLSRC
-.IP "\&"
-.CW .EXEC
-sources, don't appear in the local variables of targets that depend on
-them (nor are they touched if PMake is given the
-.B \-t
-flag).
-.Ix 0 ref flags -t
-Note that all the rules, not just that for
-.CW system ,
-include
-.CW init
-as a source. This is because none of the other targets can be made
-until
-.CW init
-has been made, thus they depend on it.
-.IP .EXPORT \n(pw
-.Ix 0 def attributes .EXPORT
-.Ix 0 def .EXPORT
-This is used to mark those targets whose creation should be sent to
-another machine if at all possible. This may be used by some
-exportation schemes if the exportation is expensive. You should ask
-your system administrator if it is necessary.
-.IP .EXPORTSAME \n(pw
-.Ix 0 def attributes .EXPORTSAME
-.Ix 0 def .EXPORTSAME
-Tells the export system that the job should be exported to a machine
-of the same architecture as the current one. Certain operations (e.g.
-running text through
-.CW nroff )
-can be performed the same on any architecture (CPU and
-operating system type), while others (e.g. compiling a program with
-.CW cc )
-must be performed on a machine with the same architecture. Not all
-export systems will support this attribute.
-.IP .IGNORE \n(pw
-.Ix 0 def attributes .IGNORE
-.Ix 0 def .IGNORE attribute
-Giving a target the
-.CW .IGNORE
-attribute causes PMake to ignore errors from any of the target's commands, as
-if they all had `\-' before them.
-.IP .INVISIBLE \n(pw
-.Ix 0 def attributes .INVISIBLE
-.Ix 0 def .INVISIBLE
-This allows you to specify one target as a source for another without
-the one affecting the other's local variables. Useful if, say, you
-have a makefile that creates two programs, one of which is used to
-create the other, so it must exist before the other is created. You
-could say
-.DS
-prog1 : $(PROG1OBJS) prog2 MAKEINSTALL
-prog2 : $(PROG2OBJS) .INVISIBLE MAKEINSTALL
-.DE
-where
-.CW MAKEINSTALL
-is some complex .USE rule (see below) that depends on the
-.Ix 0 ref .USE
-.CW .ALLSRC
-variable containing the right things. Without the
-.CW .INVISIBLE
-attribute for
-.CW prog2 ,
-the
-.CW MAKEINSTALL
-rule couldn't be applied. This is not as useful as it should be, and
-the semantics may change (or the whole thing go away) in the
-not-too-distant future.
-.IP .JOIN \n(pw
-.Ix 0 def attributes .JOIN
-.Ix 0 def .JOIN
-This is another way to avoid performing some operations in parallel
-while permitting everything else to be done so. Specifically it
-forces the target's shell script to be executed only if one or more of the
-sources was out-of-date. In addition, the target's name,
-in both its
-.CW .TARGET
-variable and all the local variables of any target that depends on it,
-is replaced by the value of its
-.CW .ALLSRC
-variable.
-As an example, suppose you have a program that has four libraries that
-compile in the same directory along with, and at the same time as, the
-program. You again have the problem with
-.CW ranlib
-that I mentioned earlier, only this time it's more severe: you
-can't just put the ranlib off to the end since the program
-will need those libraries before it can be re-created. You can do
-something like this:
-.DS
-program : $(OBJS) libraries
- cc -o $(.TARGET) $(.ALLSRC)
-
-libraries : lib1.a lib2.a lib3.a lib4.a .JOIN
- ranlib $(.OODATE)
-.DE
-.Ix 0 ref variable local .TARGET
-.Ix 0 ref variable local .ALLSRC
-.Ix 0 ref variable local .OODATE
-.Ix 0 ref .TARGET
-.Ix 0 ref .ALLSRC
-.Ix 0 ref .OODATE
-In this case, PMake will re-create the
-.CW $(OBJS)
-as necessary, along with
-.CW lib1.a ,
-.CW lib2.a ,
-.CW lib3.a
-and
-.CW lib4.a .
-It will then execute
-.CW ranlib
-on any library that was changed and set
-.CW program 's
-.CW .ALLSRC
-variable to contain what's in
-.CW $(OBJS)
-followed by
-.CW "lib1.a lib2.a lib3.a lib4.a" .'' ``
-In case you're wondering, it's called
-.CW .JOIN
-because it joins together different threads of the ``input graph'' at
-the target marked with the attribute.
-Another aspect of the .JOIN attribute is it keeps the target from
-being created if the
-.B \-t
-flag was given.
-.Ix 0 ref flags -t
-.IP .MAKE \n(pw
-.Ix 0 def attributes .MAKE
-.Ix 0 def .MAKE
-The
-.CW .MAKE
-attribute marks its target as being a recursive invocation of PMake.
-This forces PMake to execute the script associated with the target (if
-it's out-of-date) even if you gave the
-.B \-n
-or
-.B \-t
-flag. By doing this, you can start at the top of a system and type
-.DS
-pmake -n
-.DE
-and have it descend the directory tree (if your makefiles are set up
-correctly), printing what it would have executed if you hadn't
-included the
-.B \-n
-flag.
-.IP .NOEXPORT \n(pw
-.Ix 0 def attributes .NOEXPORT
-.Ix 0 def .NOEXPORT attribute
-If possible, PMake will attempt to export the creation of all targets to
-another machine (this depends on how PMake was configured). Sometimes,
-the creation is so simple, it is pointless to send it to another
-machine. If you give the target the
-.CW .NOEXPORT
-attribute, it will be run locally, even if you've given PMake the
-.B "\-L 0"
-flag.
-.IP .NOTMAIN \n(pw
-.Ix 0 def attributes .NOTMAIN
-.Ix 0 def .NOTMAIN
-Normally, if you do not specify a target to make in any other way,
-PMake will take the first target on the first dependency line of a
-makefile as the target to create. That target is known as the ``Main
-Target'' and is labeled as such if you print the dependencies out
-using the
-.B \-p
-flag.
-.Ix 0 ref flags -p
-Giving a target this attribute tells PMake that the target is
-definitely
-.I not
-the Main Target.
-This allows you to place targets in an included makefile and
-have PMake create something else by default.
-.IP .PRECIOUS \n(pw
-.Ix 0 def attributes .PRECIOUS
-.Ix 0 def .PRECIOUS attribute
-When PMake is interrupted (you type control-C at the keyboard), it
-will attempt to clean up after itself by removing any half-made
-targets. If a target has the
-.CW .PRECIOUS
-attribute, however, PMake will leave it alone. An additional side
-effect of the `::' operator is to mark the targets as
-.CW .PRECIOUS .
-.Ix 0 ref operator double-colon
-.Ix 0 ref ::
-.IP .SILENT \n(pw
-.Ix 0 def attributes .SILENT
-.Ix 0 def .SILENT attribute
-Marking a target with this attribute keeps its commands from being
-printed when they're executed, just as if they had an `@' in front of them.
-.IP .USE \n(pw
-.Ix 0 def attributes .USE
-.Ix 0 def .USE
-By giving a target this attribute, you turn it into PMake's equivalent
-of a macro. When the target is used as a source for another target,
-the other target acquires the commands, sources and attributes (except
-.CW .USE )
-of the source.
-If the target already has commands, the
-.CW .USE
-target's commands are added to the end. If more than one .USE-marked
-source is given to a target, the rules are applied sequentially.
-.IP "\&" \n(pw
-The typical .USE rule (as I call them) will use the sources of the
-target to which it is applied (as stored in the
-.CW .ALLSRC
-variable for the target) as its ``arguments,'' if you will.
-For example, you probably noticed that the commands for creating
-.CW lib1.a
-and
-.CW lib2.a
-in the example in section 3.3
-.Rm 5 3.3
-were exactly the same. You can use the
-.CW .USE
-attribute to eliminate the repetition, like so:
-.DS
-lib1.a : $(LIB1OBJS) MAKELIB
-lib2.a : $(LIB2OBJS) MAKELIB
-
-MAKELIB : .USE
- rm -f $(.TARGET)
- ar cr $(.TARGET) $(.ALLSRC)
- ...
- ranlib $(.TARGET)
-.DE
-.Ix 0 ref variable local .TARGET
-.Ix 0 ref variable local .ALLSRC
-.IP "\&" \n(pw
-Several system makefiles (not to be confused with The System Makefile)
-make use of these .USE rules to make your
-life easier (they're in the default, system makefile directory...take a look).
-Note that the .USE rule source itself
-.CW MAKELIB ) (
-does not appear in any of the targets's local variables.
-There is no limit to the number of times I could use the
-.CW MAKELIB
-rule. If there were more libraries, I could continue with
-.CW "lib3.a : $(LIB3OBJS) MAKELIB" '' ``
-and so on and so forth.
-.xH 2 Special Targets
-.LP
-As there were in Make, so there are certain targets that have special
-meaning to PMake. When you use one on a dependency line, it is the
-only target that may appear on the left-hand-side of the operator.
-.Ix 0 ref target
-.Ix 0 ref operator
-As for the attributes and variables, all the special targets
-begin with a period and consist of upper-case letters only.
-I won't describe them all in detail because some of them are rather
-complex and I'll describe them in more detail than you'll want in
-chapter 4.
-The targets are as follows:
-.nr pw 10
-.IP .BEGIN \n(pw
-.Ix 0 def .BEGIN
-Any commands attached to this target are executed before anything else
-is done. You can use it for any initialization that needs doing.
-.IP .DEFAULT \n(pw
-.Ix 0 def .DEFAULT
-This is sort of a .USE rule for any target (that was used only as a
-source) that PMake can't figure out any other way to create. It's only
-``sort of'' a .USE rule because only the shell script attached to the
-.CW .DEFAULT
-target is used. The
-.CW .IMPSRC
-variable of a target that inherits
-.CW .DEFAULT 's
-commands is set to the target's own name.
-.Ix 0 ref .IMPSRC
-.Ix 0 ref variable local .IMPSRC
-.IP .END \n(pw
-.Ix 0 def .END
-This serves a function similar to
-.CW .BEGIN ,
-in that commands attached to it are executed once everything has been
-re-created (so long as no errors occurred). It also serves the extra
-function of being a place on which PMake can hang commands you put off
-to the end. Thus the script for this target will be executed before
-any of the commands you save with the ``.\|.\|.''.
-.Ix 0 ref ...
-.IP .EXPORT \n(pw
-The sources for this target are passed to the exportation system compiled
-into PMake. Some systems will use these sources to configure
-themselves. You should ask your system administrator about this.
-.IP .IGNORE \n(pw
-.Ix 0 def .IGNORE target
-.Ix 0 ref .IGNORE attribute
-.Ix 0 ref attributes .IGNORE
-This target marks each of its sources with the
-.CW .IGNORE
-attribute. If you don't give it any sources, then it is like
-giving the
-.B \-i
-flag when you invoke PMake \*- errors are ignored for all commands.
-.Ix 0 ref flags -i
-.IP .INCLUDES \n(pw
-.Ix 0 def .INCLUDES target
-.Ix 0 def variable global .INCLUDES
-.Ix 0 def .INCLUDES variable
-The sources for this target are taken to be suffixes that indicate a
-file that can be included in a program source file.
-The suffix must have already been declared with
-.CW .SUFFIXES
-(see below).
-Any suffix so marked will have the directories on its search path
-(see
-.CW .PATH ,
-below) placed in the
-.CW .INCLUDES
-variable, each preceded by a
-.B \-I
-flag. This variable can then be used as an argument for the compiler
-in the normal fashion. The
-.CW .h
-suffix is already marked in this way in the system makefile.
-.Ix 0 ref makefile system
-E.g. if you have
-.DS
-\&.SUFFIXES : .bitmap
-\&.PATH.bitmap : /usr/local/X/lib/bitmaps
-\&.INCLUDES : .bitmap
-.DE
-PMake will place
-.CW "-I/usr/local/X/lib/bitmaps" '' ``
-in the
-.CW .INCLUDES
-variable and you can then say
-.DS
-cc $(.INCLUDES) -c xprogram.c
-.DE
-(Note: the
-.CW .INCLUDES
-variable is not actually filled in until the entire makefile has been read.)
-.IP .INTERRUPT \n(pw
-.Ix 0 def .INTERRUPT
-When PMake is interrupted,
-it will execute the commands in the script for this target, if it
-exists.
-.IP .LIBS \n(pw
-.Ix 0 def .LIBS target
-.Ix 0 def .LIBS variable
-.Ix 0 def variable global .LIBS
-This does for libraries what
-.CW .INCLUDES
-does for include files, except the flag used is
-.B \-L ,
-as required by those linkers that allow you to tell them where to find
-libraries. The variable used is
-.CW .LIBS .
-Be forewarned that PMake may not have been compiled to do this if the
-linker on your system doesn't accept the
-.B \-L
-flag, though the
-.CW .LIBS
-variable will always be defined once the makefile has been read.
-.IP .MAIN \n(pw
-.Ix 0 def .MAIN
-If you didn't give a target (or targets) to create when you invoked
-PMake, it will take the sources of this target as the targets to
-create.
-.IP .MAKEFLAGS \n(pw
-.Ix 0 def .MAKEFLAGS target
-This target provides a way for you to always specify flags for PMake
-when the makefile is used. The flags are just as they would be typed
-to the shell (except you can't use shell variables unless they're in
-the environment),
-though the
-.B \-f
-and
-.B \-r
-flags have no effect.
-.IP .NULL \n(pw
-.Ix 0 def .NULL
-.Ix 0 ref suffix null
-.Ix 0 ref "null suffix"
-This allows you to specify what suffix PMake should pretend a file has
-if, in fact, it has no known suffix. Only one suffix may be so
-designated. The last source on the dependency line is the suffix that
-is used (you should, however, only give one suffix.\|.\|.).
-.IP .PATH \n(pw
-.Ix 0 def .PATH
-If you give sources for this target, PMake will take them as
-directories in which to search for files it cannot find in the current
-directory. If you give no sources, it will clear out any directories
-added to the search path before. Since the effects of this all get
-very complex, I'll leave it til chapter four to give you a complete
-explanation.
-.IP .PATH\fIsuffix\fP \n(pw
-.Ix 0 ref .PATH
-This does a similar thing to
-.CW .PATH ,
-but it does it only for files with the given suffix. The suffix must
-have been defined already. Look at
-.B "Search Paths"
-(section 4.1)
-.Rm 6 4.1
-for more information.
-.IP .PRECIOUS \n(pw
-.Ix 0 def .PRECIOUS target
-.Ix 0 ref .PRECIOUS attribute
-.Ix 0 ref attributes .PRECIOUS
-Similar to
-.CW .IGNORE ,
-this gives the
-.CW .PRECIOUS
-attribute to each source on the dependency line, unless there are no
-sources, in which case the
-.CW .PRECIOUS
-attribute is given to every target in the file.
-.IP .RECURSIVE \n(pw
-.Ix 0 def .RECURSIVE
-.Ix 0 ref attributes .MAKE
-.Ix 0 ref .MAKE
-This target applies the
-.CW .MAKE
-attribute to all its sources. It does nothing if you don't give it any sources.
-.IP .SHELL \n(pw
-.Ix 0 def .SHELL
-PMake is not constrained to only using the Bourne shell to execute
-the commands you put in the makefile. You can tell it some other shell
-to use with this target. Check out
-.B "A Shell is a Shell is a Shell"
-(section 4.4)
-.Rm 7 4.4
-for more information.
-.IP .SILENT \n(pw
-.Ix 0 def .SILENT target
-.Ix 0 ref .SILENT attribute
-.Ix 0 ref attributes .SILENT
-When you use
-.CW .SILENT
-as a target, it applies the
-.CW .SILENT
-attribute to each of its sources. If there are no sources on the
-dependency line, then it is as if you gave PMake the
-.B \-s
-flag and no commands will be echoed.
-.IP .SUFFIXES \n(pw
-.Ix 0 def .SUFFIXES
-This is used to give new file suffixes for PMake to handle. Each
-source is a suffix PMake should recognize. If you give a
-.CW .SUFFIXES
-dependency line with no sources, PMake will forget about all the
-suffixes it knew (this also nukes the null suffix).
-For those targets that need to have suffixes defined, this is how you do it.
-.LP
-In addition to these targets, a line of the form
-.DS
-\fIattribute\fP : \fIsources\fP
-.DE
-applies the
-.I attribute
-to all the targets listed as
-.I sources .
-.xH 2 Modifying Variable Expansion
-.LP
-.Ix 0 def variable expansion modified
-.Ix 0 ref variable expansion
-.Ix 0 def variable modifiers
-Variables need not always be expanded verbatim. PMake defines several
-modifiers that may be applied to a variable's value before it is
-expanded. You apply a modifier by placing it after the variable name
-with a colon between the two, like so:
-.DS
-${\fIVARIABLE\fP:\fImodifier\fP}
-.DE
-Each modifier is a single character followed by something specific to
-the modifier itself.
-You may apply as many modifiers as you want \*- each one is applied to
-the result of the previous and is separated from the previous by
-another colon.
-.LP
-There are seven ways to modify a variable's expansion, most of which
-come from the C shell variable modification characters:
-.RS
-.IP "M\fIpattern\fP"
-.Ix 0 def :M
-.Ix 0 def modifier match
-This is used to select only those words (a word is a series of
-characters that are neither spaces nor tabs) that match the given
-.I pattern .
-The pattern is a wildcard pattern like that used by the shell, where
-.CW *
-means 0 or more characters of any sort;
-.CW ?
-is any single character;
-.CW [abcd]
-matches any single character that is either `a', `b', `c' or `d'
-(there may be any number of characters between the brackets);
-.CW [0-9]
-matches any single character that is between `0' and `9' (i.e. any
-digit. This form may be freely mixed with the other bracket form), and
-`\\' is used to escape any of the characters `*', `?', `[' or `:',
-leaving them as regular characters to match themselves in a word.
-For example, the system makefile
-.CW <makedepend.mk>
-uses
-.CW "$(CFLAGS:M-[ID]*)" '' ``
-to extract all the
-.CW \-I
-and
-.CW \-D
-flags that would be passed to the C compiler. This allows it to
-properly locate include files and generate the correct dependencies.
-.IP "N\fIpattern\fP"
-.Ix 0 def :N
-.Ix 0 def modifier nomatch
-This is identical to
-.CW :M
-except it substitutes all words that don't match the given pattern.
-.IP "S/\fIsearch-string\fP/\fIreplacement-string\fP/[g]"
-.Ix 0 def :S
-.Ix 0 def modifier substitute
-Causes the first occurrence of
-.I search-string
-in the variable to be replaced by
-.I replacement-string ,
-unless the
-.CW g
-flag is given at the end, in which case all occurrences of the string
-are replaced. The substitution is performed on each word in the
-variable in turn. If
-.I search-string
-begins with a
-.CW ^ ,
-the string must match starting at the beginning of the word. If
-.I search-string
-ends with a
-.CW $ ,
-the string must match to the end of the word (these two may be
-combined to force an exact match). If a backslash precedes these two
-characters, however, they lose their special meaning. Variable
-expansion also occurs in the normal fashion inside both the
-.I search-string
-and the
-.I replacement-string ,
-.B except
-that a backslash is used to prevent the expansion of a
-.CW $ ,
-not another dollar sign, as is usual.
-Note that
-.I search-string
-is just a string, not a pattern, so none of the usual

-.IP T
-.Ix 0 def :T
-.Ix 0 def modifier tail
-Replaces each word in the variable expansion by its last

-.DS
-OBJS = ../lib/a.o b /usr/lib/libm.a
-TAILS = $(OBJS:T)
-.DE
-the variable
-.CW TAILS
-would expand to
-.CW "a.o b libm.a" .'' ``
-.IP H
-.Ix 0 def :H
-.Ix 0 def modifier head
-This is similar to
-.CW :T ,
-except that every word is replaced by everything but the tail (the
-``head''). Using the same definition of
-.CW OBJS ,
-the string
-.CW "$(OBJS:H)" '' ``
-would expand to

-Note that the final slash on the heads is removed and
-anything without a head is replaced by the empty string.
-.IP E
-.Ix 0 def :E
-.Ix 0 def modifier extension

-In addition, the System V style of substitution is also supported.
-This looks like:

-.xH 2 More on Debugging
-.xH 2 More Exercises
-.IP (3.1)
-You've got a set programs, each of which is created from its own
-assembly-language source file (suffix
-.CW .asm ).
-Each program can be assembled into two versions, one with error-checking
-code assembled in and one without. You could assemble them into files
-with different suffixes
-.CW .eobj \& (
-and
-.CW .obj ,
-for instance), but your linker only understands files that end in
-.CW .obj .
-To top it all off, the final executables
-.I must
-have the suffix
-.CW .exe .
-How can you still use transformation rules to make your life easier
-(Hint: assume the error-checking versions have
-.CW ec
-tacked onto their prefix)?
-.IP (3.2)
-Assume, for a moment or two, you want to perform a sort of
-``indirection'' by placing the name of a variable into another one,
-then you want to get the value of the first by expanding the second
-somehow. Unfortunately, PMake doesn't allow constructs like
-.DS I
-$($(FOO))
-.DE
-What do you do? Hint: no further variable expansion is performed after
-modifiers are applied, thus if you cause a $ to occur in the
-expansion, that's what will be in the result.
-.xH 1 PMake for Gods
-.LP
-This chapter is devoted to those facilities in PMake that allow you to
-do a great deal in a makefile with very little work, as well as do
-some things you couldn't do in Make without a great deal of work (and
-perhaps the use of other programs). The problem with these features,
-is they must be handled with care, or you will end up with a mess.
-.LP
-Once more, I assume a greater familiarity with
-.UX
-or Sprite than I did in the previous two chapters.
-.xH 2 Search Paths
-.Rd 6
-.LP
-PMake supports the dispersal of files into multiple directories by
-allowing you to specify places to look for sources with
-.CW .PATH
-targets in the makefile. The directories you give as sources for these
-targets make up a ``search path.'' Only those files used exclusively
-as sources are actually sought on a search path, the assumption being
-that anything listed as a target in the makefile can be created by the
-makefile and thus should be in the current directory.
-.LP
-There are two types of search paths
-in PMake: one is used for all types of files (including included
-makefiles) and is specified with a plain
-.CW .PATH
-target (e.g.
-.CW ".PATH : RCS" ''), ``
-while the other is specific to a certain type of file, as indicated by
-the file's suffix. A specific search path is indicated by immediately following
-the
-.CW .PATH
-with the suffix of the file. For instance
-.DS
-\&.PATH.h : /sprite/lib/include /sprite/att/lib/include
-.DE
-would tell PMake to look in the directories
-.CW /sprite/lib/include
-and
-.CW /sprite/att/lib/include
-for any files whose suffix is
-.CW .h .
-.LP
-The current directory is always consulted first to see if a file
-exists. Only if it cannot be found there are the directories in the
-specific search path, followed by those in the general search path,
-consulted.
-.LP
-A search path is also used when expanding wildcard characters. If the
-pattern has a recognizable suffix on it, the path for that suffix will
-be used for the expansion. Otherwise the default search path is employed.
-.LP
-When a file is found in some directory other than the current one, all
-local variables that would have contained the target's name
-.CW .ALLSRC , (
-and
-.CW .IMPSRC )
-will instead contain the path to the file, as found by PMake.
-Thus if you have a file
-.CW ../lib/mumble.c
-and a makefile
-.DS
-\&.PATH.c : ../lib
-mumble : mumble.c
- $(CC) -o $(.TARGET) $(.ALLSRC)
-.DE
-the command executed to create
-.CW mumble
-would be
-.CW "cc -o mumble ../lib/mumble.c" .'' ``
-(As an aside, the command in this case isn't strictly necessary, since
-it will be found using transformation rules if it isn't given. This is because
-.CW .out
-is the null suffix by default and a transformation exists from
-.CW .c
-to
-.CW .out .
-Just thought I'd throw that in.)
-.LP
-If a file exists in two directories on the same search path, the file
-in the first directory on the path will be the one PMake uses. So if
-you have a large system spread over many directories, it would behoove
-you to follow a naming convention that avoids such conflicts.
-.LP
-Something you should know about the way search paths are implemented
-is that each directory is read, and its contents cached, exactly once
-\&\*- when it is first encountered \*- so any changes to the
-directories while PMake is running will not be noted when searching
-for implicit sources, nor will they be found when PMake attempts to
-discover when the file was last modified, unless the file was created in the
-current directory. While people have suggested that PMake should read
-the directories each time, my experience suggests that the caching seldom
-causes problems. In addition, not caching the directories slows things
-down enormously because of PMake's attempts to apply transformation
-rules through non-existent files \*- the number of extra file-system
-searches is truly staggering, especially if many files without
-suffixes are used and the null suffix isn't changed from
-.CW .out .
-.xH 2 Archives and Libraries
-.LP
-.UX
-and Sprite allow you to merge files into an archive using the
-.CW ar
-command. Further, if the files are relocatable object files, you can
-run
-.CW ranlib
-on the archive and get yourself a library that you can link into any
-program you want. The main problem with archives is they double the
-space you need to store the archived files, since there's one copy in
-the archive and one copy out by itself. The problem with libraries is
-you usually think of them as
-.CW -lm
-rather than
-.CW /usr/lib/libm.a
-and the linker thinks they're out-of-date if you so much as look at
-them.
-.LP
-PMake solves the problem with archives by allowing you to tell it to
-examine the files in the archives (so you can remove the individual
-files without having to regenerate them later). To handle the problem
-with libraries, PMake adds an additional way of deciding if a library
-is out-of-date:
-.IP \(bu 2
-If the table of contents is older than the library, or is missing, the
-library is out-of-date.
-.LP
-A library is any target that looks like
-.CW \-l name'' ``
-or that ends in a suffix that was marked as a library using the
-.CW .LIBS
-target.
-.CW .a
-is so marked in the system makefile.
-.LP
-Members of an archive are specified as
-``\fIarchive\fP(\fImember\fP[ \fImember\fP...])''.
-Thus
-.CW libdix.a(window.o) '' ``'
-specifies the file
-.CW window.o
-in the archive
-.CW libdix.a .
-You may also use wildcards to specify the members of the archive. Just
-remember that most the wildcard characters will only find
-.I existing
-files.
-.LP
-A file that is a member of an archive is treated specially. If the
-file doesn't exist, but it is in the archive, the modification time
-recorded in the archive is used for the file when determining if the
-file is out-of-date. When figuring out how to make an archived member target
-(not the file itself, but the file in the archive \*- the
-\fIarchive\fP(\fImember\fP) target), special care is
-taken with the transformation rules, as follows:
-.IP \(bu 2
-\&\fIarchive\fP(\fImember\fP) is made to depend on \fImember\fP.
-.IP \(bu 2
-The transformation from the \fImember\fP's suffix to the
-\fIarchive\fP's suffix is applied to the \fIarchive\fP(\fImember\fP) target.
-.IP \(bu 2
-The \fIarchive\fP(\fImember\fP)'s
-.CW .TARGET
-variable is set to the name of the \fImember\fP if \fImember\fP is
-actually a target, or the path to the member file if \fImember\fP is
-only a source.
-.IP \(bu 2
-The
-.CW .ARCHIVE
-variable for the \fIarchive\fP(\fImember\fP) target is set to the name
-of the \fIarchive\fP.
-.Ix 0 def variable local .ARCHIVE
-.Ix 0 def .ARCHIVE
-.IP \(bu 2
-The
-.CW .MEMBER
-variable is set to the actual string inside the parentheses. In most
-cases, this will be the same as the
-.CW .TARGET
-variable.
-.Ix 0 def variable local .MEMBER
-.Ix 0 def .MEMBER
-.IP \(bu 2
-The \fIarchive\fP(\fImember\fP)'s place in the local variables of the
-targets that depend on it is taken by the value of its
-.CW .TARGET
-variable.
-.LP
-Thus, a program library could be created with the following makefile:
-.DS
-\&.o.a :
- ...
- rm -f $(.TARGET:T)
-OBJS = obj1.o obj2.o obj3.o
-libprog.a : libprog.a($(OBJS))
- ar cru $(.TARGET) $(.OODATE)
- ranlib $(.TARGET)
-.DE
-This will cause the three object files to be compiled (if the
-corresponding source files were modified after the object file or, if
-that doesn't exist, the archived object file), the out-of-date ones
-archived in
-.CW libprog.a ,
-a table of contents placed in the archive and the newly-archived
-object files to be removed.
-.LP
-All this is used in the
-.CW makelib.mk
-system makefile to create a single library with ease. This makefile
-looks like this:
-.DS
-.SM
-#
-# Rules for making libraries. The object files that make up the library
-# are removed once they are archived.
-#
-# To make several libraries in parallel, you should define the variable
-# "many_libraries". This will serialize the invocations of ranlib.
-#
-# To use, do something like this:
-#
-# OBJECTS = <files in the library>
-#
-# fish.a: fish.a($(OBJECTS)) MAKELIB
-#
-#
-
-#ifndef _MAKELIB_MK
-_MAKELIB_MK =
-
-#include <po.mk>
-
-\&.po.a .o.a :
- ...
- rm -f $(.MEMBER)
-
-ARFLAGS ?= crl
-
-#
-# Re-archive the out-of-date members and recreate the library's table of
-# contents using ranlib. If many_libraries is defined, put the ranlib
-# off til the end so many libraries can be made at once.
-#
-MAKELIB : .USE .PRECIOUS
- ar $(ARFLAGS) $(.TARGET) $(.OODATE)
-#ifndef no_ranlib
-# ifdef many_libraries
- ...
-# endif /* many_libraries */
- ranlib $(.TARGET)
-#endif /* no_ranlib */
-
-#endif /* _MAKELIB_MK */
-.DE
-.xH 2 On the Condition...
-.Rd 1
-.LP
-Like the C compiler before it, PMake allows you to configure the makefile,
-based on the current environment, using conditional statements. A
-conditional looks like this:
-.DS
-#if \fIboolean expression\fP
-\fIlines\fP
-#elif \fIanother boolean expression\fP
-\fImore lines\fP
-#else
-\fIstill more lines\fP
-#endif
-.DE
-They may be nested to a maximum depth of 30 and may occur anywhere
-(except in a comment, of course). The
-.CW # '' ``
-must the very first character on the line.
-.LP
-Each
-.I "boolean expression"
-is made up of terms that look like function calls, the standard C
-boolean operators
-.CW && ,
-.CW || ,
-and
-.CW ! ,
-and the standard relational operators
-.CW == ,
-.CW != ,
-.CW > ,
-.CW >= ,
-.CW < ,
-and
-.CW <= ,
-with
-.CW ==
-and
-.CW !=
-being overloaded to allow string comparisons as well.
-.CW &&
-represents logical AND;
-.CW ||
-is logical OR and
-.CW !
-is logical NOT. The arithmetic and string operators take precedence
-over all three of these operators, while NOT takes precedence over
-AND, which takes precedence over OR. This precedence may be
-overridden with parentheses, and an expression may be parenthesized to
-your heart's content. Each term looks like a call on one of four
-functions:
-.nr pw 9
-.Ix 0 def make
-.Ix 0 def conditional make
-.Ix 0 def if make
-.IP make \n(pw
-The syntax is
-.CW make( \fItarget\fP\c
-.CW )
-where
-.I target
-is a target in the makefile. This is true if the given target was
-specified on the command line, or as the source for a
-.CW .MAIN
-target (note that the sources for
-.CW .MAIN
-are only used if no targets were given on the command line).
-.IP defined \n(pw
-.Ix 0 def defined
-.Ix 0 def conditional defined
-.Ix 0 def if defined
-The syntax is
-.CW defined( \fIvariable\fP\c
-.CW )
-and is true if
-.I variable
-is defined. Certain variables are defined in the system makefile that
-identify the system on which PMake is being run.
-.IP exists \n(pw
-.Ix 0 def exists
-.Ix 0 def conditional exists
-.Ix 0 def if exists
-The syntax is
-.CW exists( \fIfile\fP\c
-.CW )
-and is true if the file can be found on the global search path
-(i.e. that defined by
-.CW .PATH
-targets, not by
-.CW .PATH \fIsuffix\fP
-targets).
-.IP empty \n(pw
-.Ix 0 def empty
-.Ix 0 def conditional empty
-.Ix 0 def if empty
-This syntax is much like the others, except the string inside the
-parentheses is of the same form as you would put between parentheses
-when expanding a variable, complete with modifiers and everything. The
-function returns true if the resulting string is empty (NOTE: an undefined
-variable in this context will cause at the very least a warning
-message about a malformed conditional, and at the worst will cause the
-process to stop once it has read the makefile. If you want to check
-for a variable being defined or empty, use the expression
-.CW !defined( \fIvar\fP\c ``
-.CW ") || empty(" \fIvar\fP\c
-.CW ) ''
-as the definition of
-.CW ||
-will prevent the
-.CW empty()
-from being evaluated and causing an error, if the variable is
-undefined). This can be used to see if a variable contains a given
-word, for example:
-.DS
-#if !empty(\fIvar\fP:M\fIword\fP)
-.DE
-.LP
-The arithmetic and string operators may only be used to test the value
-of a variable. The lefthand side must contain the variable expansion,
-while the righthand side contains either a string, enclosed in
-double-quotes, or a number. The standard C numeric conventions (except
-for specifying an octal number) apply to both sides. E.g.
-.DS
-#if $(OS) == 4.3
-
-#if $(MACHINE) == "sun3"
-
-#if $(LOAD_ADDR) < 0xc000
-.DE
-are all valid conditionals. In addition, the numeric value of a
-variable can be tested as a boolean as follows:
-.DS
-#if $(LOAD)
-.DE
-would see if
-.CW LOAD
-contains a non-zero value and
-.DS
-#if !$(LOAD)
-.DE
-would test if
-.CW LOAD
-contains a zero value.
-.LP
-In addition to the bare
-.CW #if ,'' ``
-there are other forms that apply one of the first two functions to each
-term. They are as follows:
-.DS
- ifdef \fRdefined\fP
- ifndef \fR!defined\fP
- ifmake \fRmake\fP
- ifnmake \fR!make\fP
-.DE
-There are also the ``else if'' forms:
-.CW elif ,
-.CW elifdef ,
-.CW elifndef ,
-.CW elifmake ,
-and
-.CW elifnmake .
-.LP
-For instance, if you wish to create two versions of a program, one of which
-is optimized (the production version) and the other of which is for debugging
-(has symbols for dbx), you have two choices: you can create two
-makefiles, one of which uses the
-.CW \-g
-flag for the compilation, while the other uses the
-.CW \-O
-flag, or you can use another target (call it
-.CW debug )
-to create the debug version. The construct below will take care of
-this for you. I have also made it so defining the variable
-.CW DEBUG
-(say with
-.CW "pmake -D DEBUG" )
-will also cause the debug version to be made.
-.DS
-#if defined(DEBUG) || make(debug)
-CFLAGS += -g
-#else
-CFLAGS += -O
-#endif
-.DE
-There are, of course, problems with this approach. The most glaring
-annoyance is that if you want to go from making a debug version to
-making a production version, you have to remove all the object files,
-or you will get some optimized and some debug versions in the same
-program. Another annoyance is you have to be careful not to make two
-targets that ``conflict'' because of some conditionals in the
-makefile. For instance
-.DS
-#if make(print)
-FORMATTER = ditroff -Plaser_printer
-#endif
-#if make(draft)
-FORMATTER = nroff -Pdot_matrix_printer
-#endif
-.DE
-would wreak havoc if you tried
-.CW "pmake draft print" '' ``
-since you would use the same formatter for each target. As I said,
-this all gets somewhat complicated.
-.xH 2 A Shell is a Shell is a Shell
-.Rd 7
-.LP
-In normal operation, the Bourne Shell (better known as
-.CW sh '') ``
-is used to execute the commands to re-create targets. PMake also allows you
-to specify a different shell for it to use when executing these
-commands. There are several things PMake must know about the shell you
-wish to use. These things are specified as the sources for the
-.CW .SHELL
-.Ix 0 ref .SHELL
-.Ix 0 ref target .SHELL
-target by keyword, as follows:
-.IP "\fBpath=\fP\fIpath\fP"
-PMake needs to know where the shell actually resides, so it can
-execute it. If you specify this and nothing else, PMake will use the
-last component of the path and look in its table of the shells it
-knows and use the specification it finds, if any. Use this if you just
-want to use a different version of the Bourne or C Shell (yes, PMake knows
-how to use the C Shell too).
-.IP "\fBname=\fP\fIname\fP"
-This is the name by which the shell is to be known. It is a single
-word and, if no other keywords are specified (other than
-.B path ),
-it is the name by which PMake attempts to find a specification for
-it (as mentioned above). You can use this if you would just rather use
-the C Shell than the Bourne Shell
-.CW ".SHELL: name=csh" '' (``
-will do it).
-.IP "\fBquiet=\fP\fIecho-off command\fP"
-As mentioned before, PMake actually controls whether commands are
-printed by introducing commands into the shell's input stream. This
-keyword, and the next two, control what those commands are. The
-.B quiet
-keyword is the command used to turn echoing off. Once it is turned
-off, echoing is expected to remain off until the echo-on command is given.
-.IP "\fBecho=\fP\fIecho-on command\fP"
-The command PMake should give to turn echoing back on again.
-.IP "\fBfilter=\fP\fIprinted echo-off command\fP"
-Many shells will echo the echo-off command when it is given. This
-keyword tells PMake in what format the shell actually prints the
-echo-off command. Wherever PMake sees this string in the shell's
-output, it will delete it and any following whitespace, up to and
-including the next newline. See the example at the end of this section
-for more details.
-.IP "\fBechoFlag=\fP\fIflag to turn echoing on\fP"
-Unless a target has been marked
-.CW .SILENT ,
-PMake wants to start the shell running with echoing on. To do this, it
-passes this flag to the shell as one of its arguments. If either this
-or the next flag begins with a `\-', the flags will be passed to the
-shell as separate arguments. Otherwise, the two will be concatenated
-(if they are used at the same time, of course).
-.IP "\fBerrFlag=\fP\fIflag to turn error checking on\fP"
-Likewise, unless a target is marked
-.CW .IGNORE ,
-PMake wishes error-checking to be on from the very start. To this end,
-it will pass this flag to the shell as an argument. The same rules for
-an initial `\-' apply as for the
-.B echoFlag .
-.IP "\fBcheck=\fP\fIcommand to turn error checking on\fP"
-Just as for echo-control, error-control is achieved by inserting
-commands into the shell's input stream. This is the command to make
-the shell check for errors. It also serves another purpose if the
-shell doesn't have error-control as commands, but I'll get into that
-in a minute. Again, once error checking has been turned on, it is
-expected to remain on until it is turned off again.
-.IP "\fBignore=\fP\fIcommand to turn error checking off\fP"
-This is the command PMake uses to turn error checking off. It has
-another use if the shell doesn't do error-control, but I'll tell you
-about that.\|.\|.\|now.
-.IP "\fBhasErrCtl=\fP\fIyes or no\fP"
-This takes a value that is either
-.B yes
-or
-.B no .
-Now you might think that the existence of the
-.B check
-and
-.B ignore
-keywords would be enough to tell PMake if the shell can do
-error-control, but you'd be wrong. If
-.B hasErrCtl
-is
-.B yes ,
-PMake uses the check and ignore commands in a straight-forward manner.
-If this is
-.B no ,
-however, their use is rather different. In this case, the check
-command is used as a template, in which the string
-.B %s
-is replaced by the command that's about to be executed, to produce a
-command for the shell that will echo the command to be executed. The
-ignore command is also used as a template, again with
-.B %s
-replaced by the command to be executed, to produce a command that will
-execute the command to be executed and ignore any error it returns.
-When these strings are used as templates, you must provide newline(s)
-.CW \en '') (``
-in the appropriate place(s).
-.LP
-The strings that follow these keywords may be enclosed in single or
-double quotes (the quotes will be stripped off) and may contain the
-usual C backslash-characters (\en is newline, \er is return, \eb is
-backspace, \e' escapes a single-quote inside single-quotes, \e"
-escapes a double-quote inside double-quotes). Now for an example.
-.LP
-This is actually the contents of the
-.CW <shx.mk>
-system makefile, and causes PMake to use the Bourne Shell in such a
-way that each command is printed as it is executed. That is, if more
-than one command is given on a line, each will be printed separately.
-Similarly, each time the body of a loop is executed, the commands
-within that loop will be printed, etc. The specification runs like
-this:
-.DS
-#
-# This is a shell specification to have the Bourne shell echo
-# the commands just before executing them, rather than when it reads
-# them. Useful if you want to see how variables are being expanded, etc.
-#
-\&.SHELL : path=/bin/sh \e
- quiet="set -" \e
- echo="set -x" \e
- filter="+ set - " \e
- echoFlag=x \e
- errFlag=e \e
- hasErrCtl=yes \e
- check="set -e" \e
- ignore="set +e"
-.DE
-.LP
-It tells PMake the following:
-.Bp
-The shell is located in the file
-.CW /bin/sh .
-It need not tell PMake that the name of the shell is
-.CW sh
-as PMake can figure that out for itself (it's the last component of
-the path).
-.Bp
-The command to stop echoing is
-.CW "set -" .
-.Bp
-The command to start echoing is
-.CW "set -x" .
-.Bp
-When the echo off command is executed, the shell will print
-.CW "+ set - "
-(The `+' comes from using the
-.CW \-x
-flag (rather than the
-.CW \-v
-flag PMake usually uses)). PMake will remove all occurrences of this
-string from the output, so you don't notice extra commands you didn't
-put there.
-.Bp
-The flag the Bourne Shell will take to start echoing in this way is
-the
-.CW \-x
-flag. The Bourne Shell will only take its flag arguments concatenated
-as its first argument, so neither this nor the
-.B errFlag
-specification begins with a \-.
-.Bp
-The flag to use to turn error-checking on from the start is
-.CW \-e .
-.Bp
-The shell can turn error-checking on and off, and the commands to do
-so are
-.CW "set +e"
-and
-.CW "set -e" ,
-respectively.
-.LP
-I should note that this specification is for Bourne Shells that are
-not part of Berkeley
-.UX ,
-as shells from Berkeley don't do error control. You can get a similar
-effect, however, by changing the last three lines to be:
-.DS
- hasErrCtl=no \e
- check="echo \e"+ %s\e"\en" \e
- ignore="sh -c '%s || exit 0\en"
-.DE
-.LP
-This will cause PMake to execute the two commands
-.DS
-echo "+ \fIcmd\fP"
-sh -c '\fIcmd\fP || true'
-.DE
-for each command for which errors are to be ignored. (In case you are
-wondering, the thing for
-.CW ignore
-tells the shell to execute another shell without error checking on and
-always exit 0, since the
-.B ||
-causes the
-.CW "exit 0"
-to be executed only if the first command exited non-zero, and if the
-first command exited zero, the shell will also exit zero, since that's
-the last command it executed).
-.xH 2 Compatibility
-.Ix 0 ref compatibility
-.LP
-There are three (well, 3 \(12) levels of backwards-compatibility built
-into PMake. Most makefiles will need none at all. Some may need a
-little bit of work to operate correctly when run in parallel. Each
-level encompasses the previous levels (e.g.
-.B \-B
-(one shell per command) implies
-.B \-V )
-The three levels are described in the following three sections.
-.xH 3 DEFCON 3 \*- Variable Expansion
-.Ix 0 ref compatibility
-.LP
-As noted before, PMake will not expand a variable unless it knows of a
-value for it. This can cause problems for makefiles that expect to
-leave variables undefined except in special circumstances (e.g. if
-more flags need to be passed to the C compiler or the output from a
-text processor should be sent to a different printer). If the
-variables are enclosed in curly braces
-.CW ${PRINTER} ''), (``
-the shell will let them pass. If they are enclosed in parentheses,
-however, the shell will declare a syntax error and the make will come
-to a grinding halt.
-.LP
-You have two choices: change the makefile to define the variables
-(their values can be overridden on the command line, since that's
-where they would have been set if you used Make, anyway) or always give the
-.B \-V
-flag (this can be done with the
-.CW .MAKEFLAGS
-target, if you want).
-.xH 3 DEFCON 2 \*- The Number of the Beast
-.Ix 0 ref compatibility
-.LP
-Then there are the makefiles that expect certain commands, such as
-changing to a different directory, to not affect other commands in a
-target's creation script. You can solve this is either by going
-back to executing one shell per command (which is what the
-.B \-B
-flag forces PMake to do), which slows the process down a good bit and
-requires you to use semicolons and escaped newlines for shell constructs, or
-by changing the makefile to execute the offending command(s) in a subshell
-(by placing the line inside parentheses), like so:
-.DS
-install :: .MAKE
- (cd src; $(.PMAKE) install)
- (cd lib; $(.PMAKE) install)
- (cd man; $(.PMAKE) install)
-.DE
-.Ix 0 ref operator double-colon
-.Ix 0 ref variable global .PMAKE
-.Ix 0 ref .PMAKE
-.Ix 0 ref .MAKE
-.Ix 0 ref attribute .MAKE
-This will always execute the three makes (even if the
-.B \-n
-flag was given) because of the combination of the ``::'' operator and
-the
-.CW .MAKE
-attribute. Each command will change to the proper directory to perform
-the install, leaving the main shell in the directory in which it started.
-.xH 3 "DEFCON 1 \*- Imitation is the Not the Highest Form of Flattery"
-.Ix 0 ref compatibility
-.LP
-The final category of makefile is the one where every command requires
-input, the dependencies are incompletely specified, or you simply
-cannot create more than one target at a time, as mentioned earlier. In
-addition, you may not have the time or desire to upgrade the makefile
-to run smoothly with PMake. If you are the conservative sort, this is
-the compatibility mode for you. It is entered either by giving PMake
-the
-.B \-M
-flag (for Make), or by executing PMake as
-.CW make .'' ``
-In either case, PMake performs things exactly like Make (while still
-supporting most of the nice new features PMake provides). This
-includes:
-.IP \(bu 2
-No parallel execution.
-.IP \(bu 2
-Targets are made in the exact order specified by the makefile. The
-sources for each target are made in strict left-to-right order, etc.
-.IP \(bu 2
-A single Bourne shell is used to execute each command, thus the
-shell's
-.CW $$
-variable is useless, changing directories doesn't work across command
-lines, etc.
-.IP \(bu 2
-If no special characters exist in a command line, PMake will break the
-command into words itself and execute the command directly, without
-executing a shell first. The characters that cause PMake to execute a
-shell are:
-.CW # ,
-.CW = ,
-.CW | ,
-.CW ^ ,
-.CW ( ,
-.CW ) ,
-.CW { ,
-.CW } ,
-.CW ; ,
-.CW & ,
-.CW < ,
-.CW > ,
-.CW * ,
-.CW ? ,
-.CW [ ,
-.CW ] ,
-.CW : ,
-.CW $ ,
-.CW ` ,
-and
-.CW \e .
-You should notice that these are all the characters that are given
-special meaning by the shell (except
-.CW '
-and
-.CW " ,
-which PMake deals with all by its lonesome).
-.IP \(bu 2
-The use of the null suffix is turned off.
-.Ix 0 ref "null suffix"
-.Ix 0 ref suffix null
-.xH 2 The Way Things Work
-.LP
-When PMake reads the makefile, it parses sources and targets into
-nodes in a graph. The graph is directed only in the sense that PMake
-knows which way is up. Each node contains not only links to all its
-parents and children (the nodes that depend on it and those on which
-it depends, respectively), but also a count of the number of its
-children that have already been processed.
-.LP
-The most important thing to know about how PMake uses this graph is
-that the traversal is breadth-first and occurs in two passes.
-.LP
-After PMake has parsed the makefile, it begins with the nodes the user
-has told it to make (either on the command line, or via a
-.CW .MAIN
-target, or by the target being the first in the file not labeled with
-the
-.CW .NOTMAIN
-attribute) placed in a queue. It continues to take the node off the
-front of the queue, mark it as something that needs to be made, pass
-the node to
-.CW Suff_FindDeps
-(mentioned earlier) to find any implicit sources for the node, and
-place all the node's children that have yet to be marked at the end of
-the queue. If any of the children is a
-.CW .USE
-rule, its attributes are applied to the parent, then its commands are
-appended to the parent's list of commands and its children are linked
-to its parent. The parent's unmade children counter is then decremented
-(since the
-.CW .USE
-node has been processed). You will note that this allows a
-.CW .USE
-node to have children that are
-.CW .USE
-nodes and the rules will be applied in sequence.
-If the node has no children, it is placed at the end of
-another queue to be examined in the second pass. This process
-continues until the first queue is empty.
-.LP
-At this point, all the leaves of the graph are in the examination
-queue. PMake removes the node at the head of the queue and sees if it
-is out-of-date. If it is, it is passed to a function that will execute
-the commands for the node asynchronously. When the commands have
-completed, all the node's parents have their unmade children counter
-decremented and, if the counter is then 0, they are placed on the
-examination queue. Likewise, if the node is up-to-date. Only those
-parents that were marked on the downward pass are processed in this
-way. Thus PMake traverses the graph back up to the nodes the user
-instructed it to create. When the examination queue is empty and no
-shells are running to create a target, PMake is finished.
-.LP
-Once all targets have been processed, PMake executes the commands
-attached to the
-.CW .END
-target, either explicitly or through the use of an ellipsis in a shell
-script. If there were no errors during the entire process but there
-are still some targets unmade (PMake keeps a running count of how many
-targets are left to be made), there is a cycle in the graph. PMake does
-a depth-first traversal of the graph to find all the targets that
-weren't made and prints them out one by one.
-.xH 1 Answers to Exercises
-.IP (3.1)
-This is something of a trick question, for which I apologize. The
-trick comes from the UNIX definition of a suffix, which PMake doesn't
-necessarily share. You will have noticed that all the suffixes used in
-this tutorial (and in UNIX in general) begin with a period
-.CW .ms , (
-.CW .c ,
-etc.). Now, PMake's idea of a suffix is more like English's: it's the
-characters at the end of a word. With this in mind, one possible
-.Ix 0 def suffix
-solution to this problem goes as follows:
-.DS I
-\&.SUFFIXES : ec.exe .exe ec.obj .obj .asm
-ec.objec.exe .obj.exe :
- link -o $(.TARGET) $(.IMPSRC)
-\&.asmec.obj :
- asm -o $(.TARGET) -DDO_ERROR_CHECKING $(.IMPSRC)
-\&.asm.obj :
- asm -o $(.TARGET) $(.IMPSRC)
-.DE
-.IP (3.2)
-The trick to this one lies in the ``:='' variable-assignment operator
-and the ``:S'' variable-expansion modifier.
-.Ix 0 ref variable assignment expanded
-.Ix 0 ref variable expansion modified
-.Ix 0 ref modifier substitute
-.Ix 0 ref :S
-.Ix 0 ref :=
-Basically what you want is to take the pointer variable, so to speak,
-and transform it into an invocation of the variable at which it
-points. You might try something like
-.DS I
-$(PTR:S/^/\e$(/:S/$/))
-.DE
-which places
-.CW $( '' ``
-at the front of the variable name and
-.CW ) '' ``
-at the end, thus transforming
-.CW VAR ,'' ``
-for example, into
-.CW $(VAR) ,'' ``
-which is just what we want. Unfortunately (as you know if you've tried
-it), since, as it says in the hint, PMake does no further substitution
-on the result of a modified expansion, that's \fIall\fP you get. The
-solution is to make use of ``:='' to place that string into yet
-another variable, then invoke the other variable directly:
-.DS I
-*PTR := $(PTR:S/^/\e$(/:S/$/)/)
-.DE
-You can then use
-.CW $(*PTR) '' ``
-to your heart's content.

-.xH 1 Glossary of Jargon
-.Gp "attribute"
-A property given to a target that causes PMake to treat it differently.
-.Gp "command script"
-The lines immediately following a dependency line that specify
-commands to execute to create each of the targets on the dependency
-line. Each line in the command script must begin with a tab.
-.Gp "command-line variable"
-A variable defined in an argument when PMake is first executed.
-Overrides all assignments to the same variable name in the makefile.
-.Gp "conditional"
-A construct much like that used in C that allows a makefile to be
-configured on the fly based on the local environment, or on what is being
-made by that invocation of PMake.
-.Gp "creation script"
-Commands used to create a target. See ``command script.''
-.Gp "dependency"
-The relationship between a source and a target. This comes in three
-flavors, as indicated by the operator between the target and the
-source. `:' gives a straight time-wise dependency (if the target is
-older than the source, the target is out-of-date), while `!' provides
-simply an ordering and always considers the target out-of-date. `::'
-is much like `:', save it creates multiple instances of a target each
-of which depends on its own list of sources.
-.Gp "dynamic source"
-This refers to a source that has a local variable invocation in it. It
-allows a single dependency line to specify a different source for each
-target on the line.
-.Gp "global variable"
-Any variable defined in a makefile. Takes precedence over variables
-defined in the environment, but not over command-line or local variables.
-.Gp "input graph"
-What PMake constructs from a makefile. Consists of nodes made of the
-targets in the makefile, and the links between them (the
-dependencies). The links are directed (from source to target) and
-there may not be any cycles (loops) in the graph.
-.Gp "local variable"
-A variable defined by PMake visible only in a target's shell script.
-There are seven local variables, not all of which are defined for
-every target:
-.CW .TARGET ,
-.CW .ALLSRC ,
-.CW .OODATE ,
-.CW .PREFIX ,
-.CW .IMPSRC ,
-.CW .ARCHIVE ,
-and
-.CW .MEMBER .
-.CW .TARGET ,
-.CW .PREFIX ,
-.CW .ARCHIVE ,
-and
-.CW .MEMBER
-may be used on dependency lines to create ``dynamic sources.''
-.Gp "makefile"
-A file that describes how a system is built. If you don't know what it
-is after reading this tutorial.\|.\|.\|.
-.Gp "modifier"
-A letter, following a colon, used to alter how a variable is expanded.
-It has no effect on the variable itself.
-.Gp "operator"
-What separates a source from a target (on a dependency line) and specifies
-the relationship between the two. There are three:
-.CW : ', `
-.CW :: ', `
-and
-.CW ! '. `
-.Gp "search path"
-A list of directories in which a file should be sought. PMake's view
-of the contents of directories in a search path does not change once
-the makefile has been read. A file is sought on a search path only if
-it is exclusively a source.
-.Gp "shell"
-A program to which commands are passed in order to create targets.
-.Gp "source"
-Anything to the right of an operator on a dependency line. Targets on
-the dependency line are usually created from the sources.
-.Gp "special target"
-A target that causes PMake to do special things when it's encountered.
-.Gp "suffix"
-The tail end of a file name. Usually begins with a period,
-.CW .c
-or
-.CW .ms ,
-e.g.
-.Gp "target"
-A word to the left of the operator on a dependency line. More
-generally, any file that PMake might create. A file may be (and often
-is) both a target and a source (what it is depends on how PMake is
-looking at it at the time \*- sort of like the wave/particle duality
-of light, you know).
-.Gp "transformation rule"
-A special construct in a makefile that specifies how to create a file
-of one type from a file of another, as indicated by their suffixes.
-.Gp "variable expansion"
-The process of substituting the value of a variable for a reference to
-it. Expansion may be altered by means of modifiers.
-.Gp "variable"
-A place in which to store text that may be retrieved later. Also used
-to define the local environment. Conditionals exist that test whether
-a variable is defined or not.

+.xH 1 Introduction
+.LP
+PMake is a program for creating other programs, or anything else you
+can think of for it to do. The basic idea behind PMake is that, for
+any given system, be it a program or a document or whatever, there
+will be some files that depend on the state of other files (on when
+they were last modified). PMake takes these dependencies, which you
+must specify, and uses them to build whatever it is you want it to
+build.
+.LP
+PMake is almost fully-compatible with Make, with which you may already
+be familiar. PMake's most important feature is its ability to run
+several different jobs at once, making the creation of systems
+considerably faster. It also has a great deal more functionality than
+Make. Throughout the text, whenever something is mentioned that is an
+important difference between PMake and Make (i.e. something that will
+cause a makefile to fail if you don't do something about it), or is
+simply important, it will be flagged with a little sign in the left
+margin, like this:
+.No
+.LP
+This tutorial is divided into three main sections corresponding to basic,
+intermediate and advanced PMake usage. If you already know Make well,
+you will only need to skim chapter 2 (there are some aspects of
+PMake that I consider basic to its use that didn't exist in Make).
+Things in chapter 3 make life much easier, while those in chapter 4
+are strictly for those who know what they are doing. Chapter 5 has
+definitions for the jargon I use and chapter 6 contains possible
+solutions to the problems presented throughout the tutorial.
+.xH 1 The Basics of PMake
+.LP
+PMake takes as input a file that tells a) which files depend on which
+other files to be complete and b) what to do about files that are
+``out-of-date.'' This file is known as a ``makefile'' and is usually
+.Ix 0 def makefile
+kept in the top-most directory of the system to be built. While you
+can call the makefile anything you want, PMake will look for
+.CW Makefile
+and
+.CW makefile
+(in that order) in the current directory if you don't tell it
+otherwise.
+.Ix 0 def makefile default
+To specify a different makefile, use the
+.B \-f
+flag (e.g.
+.CW "pmake -f program.mk" ''). ``
+.Ix 0 ref flags -f
+.Ix 0 ref makefile other
+.LP
+A makefile has four different types of lines in it:
+.RS
+.IP \(bu 2
+File dependency specifications
+.IP \(bu 2
+Creation commands
+.IP \(bu 2
+Variable assignments
+.IP \(bu 2
+Comments, include statements and conditional directives
+.RE
+.LP
+Any line may be continued over multiple lines by ending it with a
+backslash.
+.Ix 0 def "continuation line"
+The backslash, following newline and any initial whitespace
+on the following line are compressed into a single space before the
+input line is examined by PMake.
+.xH 2 Dependency Lines
+.LP
+As mentioned in the introduction, in any system, there are
+dependencies between the files that make up the system. For instance,
+in a program made up of several C source files and one header file,
+the C files will need to be re-compiled should the header file be
+changed. For a document of several chapters and one macro file, the
+chapters will need to be reprocessed if any of the macros changes.
+.Ix 0 def "dependency"
+These are dependencies and are specified by means of dependency lines in
+the makefile.
+.LP
+.Ix 0 def "dependency line"
+On a dependency line, there are targets and sources, separated by a
+one- or two-character operator.
+The targets ``depend'' on the sources and are usually created from
+them.
+.Ix 0 def target
+.Ix 0 def source
+.Ix 0 ref operator
+Any number of targets and sources may be specified on a dependency line.
+All the targets in the line are made to depend on all the sources.
+Targets and sources need not be actual files, but every source must be
+either an actual file or another target in the makefile.
+If you run out of room, use a backslash at the end of the line to continue onto
+the next one.
+.LP
+Any file may be a target and any file may be a source, but the
+relationship between the two (or however many) is determined by the
+``operator'' that separates them.
+.Ix 0 def operator
+Three types of operators exist: one specifies that the datedness of a
+target is determined by the state of its sources, while another
+specifies other files (the sources) that need to be dealt with before
+the target can be re-created. The third operator is very similar to
+the first, with the additional condition that the target is
+out-of-date if it has no sources. These operations are represented by
+the colon, the exclamation point and the double-colon, respectively, and are
+mutually exclusive. Their exact semantics are as follows:
+.IP ":"
+.Ix 0 def operator colon
+.Ix 0 def :
+If a colon is used, a target on the line is considered to be
+``out-of-date'' (and in need of creation) if
+.RS
+.IP \(bu 2
+any of the sources has been modified more recently than the target, or
+.IP \(bu 2
+the target doesn't exist.
+.RE

+.LP
+Enough words, now for an example. Take that C program I mentioned
+earlier. Say there are three C files
+.CW a.c , (
+.CW b.c
+and
+.CW c.c )
+each of which
+includes the file
+.CW defs.h .
+The dependencies between the files could then be expressed as follows:
+.DS
+program : a.o b.o c.o
+a.o b.o c.o : defs.h
+a.o : a.c
+b.o : b.c
+c.o : c.c
+.DE
+.LP
+You may be wondering at this point, where
+.CW a.o ,
+.CW b.o
+and
+.CW c.o
+came in and why
+.I they
+depend on
+.CW defs.h
+and the C files don't. The reason is quite simple:
+.CW program
+cannot be made by linking together .c files \*- it must be
+made from .o files. Likewise, if you change
+.CW defs.h ,
+it isn't the .c files that need to be re-created, it's the .o files.
+If you think of dependencies in these terms \*- which files (targets)
+need to be created from which files (sources) \*- you should have no problems.
+.LP
+An important thing to notice about the above example, is that all the
+\&.o files appear as targets on more than one line. This is perfectly
+all right: the target is made to depend on all the sources mentioned
+on all the dependency lines. E.g.
+.CW a.o
+depends on both
+.CW defs.h
+and
+.CW a.c .
+.Ix 0 ref dependency
+.No
+.LP
+The order of the dependency lines in the makefile is
+important: the first target on the first dependency line in the
+makefile will be the one that gets made if you don't say otherwise.
+That's why
+.CW program
+comes first in the example makefile, above.
+.LP
+Both targets and sources may contain the standard C-Shell wildcard
+characters
+.CW { , (
+.CW } ,
+.CW * ,
+.CW ? ,
+.CW [ ,
+and
+.CW ] ),
+but the non-curly-brace ones may only appear in the final component
+(the file portion) of the target or source. The characters mean the
+following things:
+.IP \fB{}\fP
+These enclose a comma-separated list of options and cause the pattern
+to be expanded once for each element of the list. Each expansion
+contains a different element. For example,
+.CW src/{whiffle,beep,fish}.c
+expands to the three words
+.CW src/whiffle.c ,
+.CW src/beep.c ,
+and
+.CW src/fish.c .
+These braces may be nested and, unlike the other wildcard characters,
+the resulting words need not be actual files. All other wildcard
+characters are expanded using the files that exist when PMake is
+started.
+.IP \fB*\fP
+This matches zero or more characters of any sort.
+.CW src/*.c
+will expand to the same three words as above as long as
+.CW src
+contains those three files (and no other files that end in
+.CW .c ).
+.IP \fB?\fP
+Matches any single character.
+.IP \fB[]\fP
+This is known as a character class and contains either a list of
+single characters, or a series of character ranges
+.CW a-z , (
+for example means all characters between a and z), or both. It matches
+any single character contained in the list. E.g.
+.CW [A-Za-z]
+will match all letters, while
+.CW [0123456789]
+will match all numbers.
+.xH 2 Shell Commands
+.LP
+``Isn't that nice,'' you say to yourself, ``but how are files
+actually `re-created,' as he likes to spell it?''
+The re-creation is accomplished by commands you place in the makefile.
+These commands are passed to the Bourne shell (better known as
+``/bin/sh'') to be executed and are
+.Ix 0 ref shell
+.Ix 0 ref re-creation
+.Ix 0 ref update
+expected to do what's necessary to update the target file (PMake
+doesn't actually check to see if the target was created. It just
+assumes it's there).
+.Ix 0 ref target
+.LP
+Shell commands in a makefile look a lot like shell commands you would
+type at a terminal, with one important exception: each command in a
+makefile
+.I must
+be preceded by at least one tab.
+.LP
+Each target has associated with it a shell script made up of
+one or more of these shell commands. The creation script for a target
+should immediately follow the dependency line for that target. While
+any given target may appear on more than one dependency line, only one
+of these dependency lines may be followed by a creation script, unless
+the `::' operator was used on the dependency line.
+.Ix 0 ref operator double-colon
+.Ix 0 ref ::
+.No
+.LP
+If the double-colon was used, each dependency line for the target
+may be followed by a shell script. That script will only be executed
+if the target on the associated dependency line is out-of-date with
+respect to the sources on that line, according to the rules I gave
+earlier.
+I'll give you a good example of this later on.
+.LP
+To expand on the earlier makefile, you might add commands as follows:
+.DS
+program : a.o b.o c.o
+ cc a.o b.o c.o \-o program
+a.o b.o c.o : defs.h
+a.o : a.c
+ cc \-c a.c
+b.o : b.c
+ cc \-c b.c
+c.o : c.c
+ cc \-c c.c
+.DE
+.LP
+Something you should remember when writing a makefile is, the
+commands will be executed if the
+.I target
+on the dependency line is out-of-date, not the sources.
+.Ix 0 ref target
+.Ix 0 ref source
+.Ix 0 ref out-of-date
+In this example, the command
+.CW "cc \-c a.c" '' ``
+will be executed if
+.CW a.o
+is out-of-date. Because of the `:' operator,
+.Ix 0 ref :
+.Ix 0 ref operator colon
+this means that should
+.CW a.c
+.I or
+.CW defs.h
+have been modified more recently than
+.CW a.o ,
+the command will be executed
+.CW a.o "\&" (
+will be considered out-of-date).
+.Ix 0 ref out-of-date
+.LP
+Remember how I said the only difference between a makefile shell
+command and a regular shell command was the leading tab? I lied. There
+is another way in which makefile commands differ from regular ones.
+The first two characters after the initial whitespace are treated
+specially.
+If they are any combination of `@' and `\-', they cause PMake to do
+different things.
+.LP
+In most cases, shell commands are printed before they're
+actually executed. This is to keep you informed of what's going on. If
+an `@' appears, however, this echoing is suppressed. In the case of an
+.CW echo
+command, say
+.CW "echo Linking index" ,'' ``
+it would be
+rather silly to see
+.DS
+echo Linking index
+Linking index
+.DE
+.LP
+so PMake allows you to place an `@' before the command
+.CW "@echo Linking index" '') (``
+to prevent the command from being printed.
+.LP
+The other special character is the `\-'. In case you didn't know,
+shell commands finish with a certain ``exit status.'' This status is
+made available by the operating system to whatever program invoked the
+command. Normally this status will be 0 if everything went ok and
+non-zero if something went wrong. For this reason, PMake will consider
+an error to have occurred if one of the shells it invokes returns a non-zero
+status. When it detects an error, PMake's usual action is to abort
+whatever it's doing and exit with a non-zero status itself (any other
+targets that were being created will continue being made, but nothing
+new will be started. PMake will exit after the last job finishes).
+This behavior can be altered, however, by placing a `\-' at the front
+of a command
+.CW "\-mv index index.old" ''), (``
+certain command-line arguments,
+or doing other things, to be detailed later. In such
+a case, the non-zero status is simply ignored and PMake keeps chugging
+along.
+.No
+.LP
+Because all the commands are given to a single shell to execute, such
+things as setting shell variables, changing directories, etc., last
+beyond the command in which they are found. This also allows shell
+compound commands (like
+.CW for
+loops) to be entered in a natural manner.
+Since this could cause problems for some makefiles that depend on
+each command being executed by a single shell, PMake has a
+.B \-B
+.Ix 0 ref compatibility
+.Ix 0 ref flags -B
+flag (it stands for backwards-compatible) that forces each command to
+be given to a separate shell. It also does several other things, all
+of which I discourage since they are now old-fashioned.\|.\|.\|.
+.No
+.LP
+A target's shell script is fed to the shell on its (the shell's) input stream.
+This means that any commands, such as
+.CW ci
+that need to get input from the terminal won't work right \*- they'll
+get the shell's input, something they probably won't find to their
+liking. A simple way around this is to give a command like this:
+.DS
+ci $(SRCS) < /dev/tty
+.DE
+This would force the program's input to come from the terminal. If you
+can't do this for some reason, your only other alternative is to use
+PMake in its fullest compatibility mode. See
+.B Compatibility
+in chapter 4.
+.Ix 0 ref compatibility
+.LP
+.xH 2 Variables
+.LP
+PMake, like Make before it, has the ability to save text in variables
+to be recalled later at your convenience. Variables in PMake are used
+much like variables in the shell and, by tradition, consist of
+all upper-case letters (you don't
+.I have
+to use all upper-case letters.
+In fact there's nothing to stop you from calling a variable
+.CW @^&$%$ .
+Just tradition). Variables are assigned-to using lines of the form
+.Ix 0 def variable assignment
+.DS
+VARIABLE = value
+.DE
+.Ix 0 def variable assignment
+appended-to by
+.DS
+VARIABLE += value
+.DE
+.Ix 0 def variable appending
+.Ix 0 def variable assignment appended
+.Ix 0 def +=
+conditionally assigned-to (if the variable isn't already defined) by
+.DS
+VARIABLE ?= value
+.DE
+.Ix 0 def variable assignment conditional
+.Ix 0 def ?=
+and assigned-to with expansion (i.e. the value is expanded (see below)
+before being assigned to the variable\*-useful for placing a value at
+the beginning of a variable, or other things) by
+.DS
+VARIABLE := value
+.DE
+.Ix 0 def variable assignment expanded
+.Ix 0 def :=
+.LP
+Any whitespace before
+.I value
+is stripped off. When appending, a space is placed between the old
+value and the stuff being appended.
+.LP
+The final way a variable may be assigned to is using
+.DS
+VARIABLE != shell-command
+.DE
+.Ix 0 def variable assignment shell-output
+.Ix 0 def !=
+In this case,
+.I shell-command
+has all its variables expanded (see below) and is passed off to a
+shell to execute. The output of the shell is then placed in the
+variable. Any newlines (other than the final one) are replaced by
+spaces before the assignment is made. This is typically used to find
+the current directory via a line like:
+.DS
+CWD != pwd
+.DE
+.LP
+.B Note:
+this is intended to be used to execute commands that produce small amounts
+of output (e.g. ``pwd''). The implementation is less than intelligent and will
+likely freeze if you execute something that produces thousands of
+bytes of output (8 Kb is the limit on many UNIX systems).
+.LP
+The value of a variable may be retrieved by enclosing the variable
+name in parentheses or curly braces and preceding the whole thing
+with a dollar sign.
+.LP
+For example, to set the variable CFLAGS to the string
+.CW "\-I/sprite/src/lib/libc \-O" ,'' ``
+you would place a line
+.DS
+CFLAGS = \-I/sprite/src/lib/libc \-O
+.DE
+in the makefile and use the word
+.CW "$(CFLAGS)"
+wherever you would like the string
+.CW "\-I/sprite/src/lib/libc \-O"
+to appear. This is called variable expansion.
+.Ix 0 def variable expansion
+.No
+.LP
+Unlike Make, PMake will not expand a variable unless it knows
+the variable exists. E.g. if you have a
+.CW "${i}"
+in a shell command and you have not assigned a value to the variable
+.CW i
+(the empty string is considered a value, by the way), where Make would have
+substituted the empty string, PMake will leave the
+.CW "${i}"
+alone.
+To keep PMake from substituting for a variable it knows, precede the
+dollar sign with another dollar sign.
+(e.g. to pass
+.CW "${HOME}"
+to the shell, use
+.CW "$${HOME}" ).
+This causes PMake, in effect, to expand the
+.CW $
+macro, which expands to a single
+.CW $ .
+For compatibility, Make's style of variable expansion will be used
+if you invoke PMake with any of the compatibility flags (\c
+.B \-V ,
+.B \-B
+or
+.B \-M .
+The
+.B \-V
+flag alters just the variable expansion).
+.Ix 0 ref flags -V
+.Ix 0 ref flags -B
+.Ix 0 ref flags -M
+.Ix 0 ref compatibility
+.LP
+.Ix 0 ref variable expansion
+There are two different times at which variable expansion occurs:
+When parsing a dependency line, the expansion occurs immediately
+upon reading the line. If any variable used on a dependency line is
+undefined, PMake will print a message and exit.
+Variables in shell commands are expanded when the command is
+executed.
+Variables used inside another variable are expanded whenever the outer
+variable is expanded (the expansion of an inner variable has no effect
+on the outer variable. I.e. if the outer variable is used on a dependency
+line and in a shell command, and the inner variable changes value
+between when the dependency line is read and the shell command is
+executed, two different values will be substituted for the outer
+variable).
+.Ix 0 def variable types
+.LP
+Variables come in four flavors, though they are all expanded the same
+and all look about the same. They are (in order of expanding scope):
+.RS
+.IP \(bu 2
+Local variables.
+.Ix 0 ref variable local
+.IP \(bu 2
+Command-line variables.
+.Ix 0 ref variable command-line
+.IP \(bu 2
+Global variables.
+.Ix 0 ref variable global
+.IP \(bu 2
+Environment variables.
+.Ix 0 ref variable environment
+.RE
+.LP
+The classification of variables doesn't matter much, except that the
+classes are searched from the top (local) to the bottom (environment)
+when looking up a variable. The first one found wins.
+.xH 3 Local Variables
+.LP
+.Ix 0 def variable local
+Each target can have as many as seven local variables. These are
+variables that are only ``visible'' within that target's shell script
+and contain such things as the target's name, all of its sources (from
+all its dependency lines), those sources that were out-of-date, etc.
+Four local variables are defined for all targets. They are:
+.RS
+.IP ".TARGET"
+.Ix 0 def variable local .TARGET
+.Ix 0 def .TARGET
+The name of the target.
+.IP ".OODATE"
+.Ix 0 def variable local .OODATE
+.Ix 0 def .OODATE
+The list of the sources for the target that were considered out-of-date.
+The order in the list is not guaranteed to be the same as the order in
+which the dependencies were given.
+.IP ".ALLSRC"
+.Ix 0 def variable local .ALLSRC
+.Ix 0 def .ALLSRC
+The list of all sources for this target in the order in which they
+were given.
+.IP ".PREFIX"
+.Ix 0 def variable local .PREFIX
+.Ix 0 def .PREFIX
+The target without its suffix and without any leading path. E.g. for
+the target
+.CW ../../lib/compat/fsRead.c ,
+this variable would contain
+.CW fsRead .
+.RE
+.LP
+Three other local variables are set only for certain targets under
+special circumstances. These are the ``.IMPSRC,''
+.Ix 0 ref variable local .IMPSRC
+.Ix 0 ref .IMPSRC
+``.ARCHIVE,''
+.Ix 0 ref variable local .ARCHIVE
+.Ix 0 ref .ARCHIVE
+and ``.MEMBER''
+.Ix 0 ref variable local .MEMBER
+.Ix 0 ref .MEMBER
+variables. When they are set and how they are used is described later.
+.LP
+Four of these variables may be used in sources as well as in shell
+scripts.
+.Ix 0 def "dynamic source"
+.Ix 0 def source dynamic
+These are ``.TARGET'', ``.PREFIX'', ``.ARCHIVE'' and ``.MEMBER''. The
+variables in the sources are expanded once for each target on the
+dependency line, providing what is known as a ``dynamic source,''
+.Rd 0
+allowing you to specify several dependency lines at once. For example,
+.DS
+$(OBJS) : $(.PREFIX).c
+.DE
+will create a dependency between each object file and its
+corresponding C source file.
+.xH 3 Command-line Variables
+.LP
+.Ix 0 def variable command-line
+Command-line variables are set when PMake is first invoked by giving a
+variable assignment as one of the arguments. For example,
+.DS
+pmake "CFLAGS = -I/sprite/src/lib/libc -O"
+.DE
+would make
+.CW CFLAGS
+be a command-line variable with the given value. Any assignments to
+.CW CFLAGS
+in the makefile will have no effect, because once it
+is set, there is (almost) nothing you can do to change a command-line
+variable (the search order, you see). Command-line variables may be
+set using any of the four assignment operators, though only
+.CW =
+and
+.CW ?=
+behave as you would expect them to, mostly because assignments to
+command-line variables are performed before the makefile is read, thus
+the values set in the makefile are unavailable at the time.
+.CW +=
+.Ix 0 ref +=
+.Ix 0 ref variable assignment appended
+is the same as
+.CW = ,
+because the old value of the variable is sought only in the scope in
+which the assignment is taking place (for reasons of efficiency that I
+won't get into here).
+.CW :=
+and
+.CW ?=
+.Ix 0 ref :=
+.Ix 0 ref ?=
+.Ix 0 ref variable assignment expanded
+.Ix 0 ref variable assignment conditional
+will work if the only variables used are in the environment.
+.CW !=
+is sort of pointless to use from the command line, since the same
+effect can no doubt be accomplished using the shell's own command
+substitution mechanisms (backquotes and all that).
+.xH 3 Global Variables
+.LP
+.Ix 0 def variable global
+Global variables are those set or appended-to in the makefile.
+There are two classes of global variables: those you set and those PMake sets.
+As I said before, the ones you set can have any name you want them to have,
+except they may not contain a colon or an exclamation point.
+The variables PMake sets (almost) always begin with a
+period and always contain upper-case letters, only. The variables are
+as follows:
+.RS
+.IP .PMAKE
+.Ix 0 def variable global .PMAKE
+.Ix 0 def .PMAKE
+.Ix 0 def variable global MAKE
+.Ix 0 def MAKE
+The name by which PMake was invoked is stored in this variable. For
+compatibility, the name is also stored in the MAKE variable.
+.IP .MAKEFLAGS
+.Ix 0 def variable global .MAKEFLAGS
+.Ix 0 def .MAKEFLAGS variable
+.Ix 0 def variable global MFLAGS
+.Ix 0 def MFLAGS
+All the relevant flags with which PMake was invoked. This does not
+include such things as
+.B \-f
+or variable assignments. Again for compatibility, this value is stored
+in the MFLAGS variable as well.
+.RE
+.LP
+Two other variables, ``.INCLUDES'' and ``.LIBS,'' are covered in the
+section on special targets in chapter 3.
+.Ix 0 ref variable global .INCLUDES
+.Ix 0 ref variable global .LIBS
+.LP
+Global variables may be deleted using lines of the form:
+.Ix 0 def #undef
+.Ix 0 def variable deletion
+.DS
+#undef \fIvariable\fP
+.DE
+The
+.CW # ' `
+must be the first character on the line. Note that this may only be
+done on global variables.
+.xH 3 Environment Variables
+.LP
+.Ix 0 def variable environment
+Environment variables are passed by the shell that invoked PMake and
+are given by PMake to each shell it invokes. They are expanded like
+any other variable, but they cannot be altered in any way.
+.LP
+One special environment variable,
+.CW PMAKE ,
+.Ix 0 def variable environment PMAKE
+is examined by PMake for command-line flags, variable assignments,
+etc., it should always use. This variable is examined before the
+actual arguments to PMake are. In addition, all flags given to PMake,
+either through the
+.CW PMAKE
+variable or on the command line, are placed in this environment
+variable and exported to each shell PMake executes. Thus recursive
+invocations of PMake automatically receive the same flags as the
+top-most one.
+.LP
+Using all these variables, you can compress the sample makefile even more:
+.DS
+OBJS = a.o b.o c.o
+program : $(OBJS)
+ cc $(.ALLSRC) \-o $(.TARGET)
+$(OBJS) : defs.h
+a.o : a.c
+ cc \-c a.c
+b.o : b.c
+ cc \-c b.c
+c.o : c.c
+ cc \-c c.c
+.DE
+.Ix 0 ref variable local .ALLSRC
+.Ix 0 ref .ALLSRC
+.Ix 0 ref variable local .TARGET
+.Ix 0 ref .TARGET
+.Rd 3
+.xH 2 Comments
+.LP
+.Ix 0 def comments
+Comments in a makefile start with a `#' character and extend to the
+end of the line. They may appear
+anywhere you want them, except in a shell command (though the shell
+will treat it as a comment, too). If, for some reason, you need to use the `#'
+in a variable or on a dependency line, put a backslash in front of it.
+PMake will compress the two into a single `#' (Note: this isn't true
+if PMake is operating in full-compatibility mode).
+.Ix 0 ref flags -M
+.Ix 0 ref compatibility
+.xH 2 Parallelism
+.No
+.LP
+PMake was specifically designed to re-create several targets at once,
+when possible. You do not have to do anything special to cause this to
+happen (unless PMake was configured to not act in parallel, in which
+case you will have to make use of the
+.B \-L
+and
+.B \-J
+flags (see below)),
+.Ix 0 ref flags -L
+.Ix 0 ref flags -J
+but you do have to be careful at times.
+.LP
+There are several problems you are likely to encounter. One is
+that some makefiles (and programs) are written in such a way that it is
+impossible for two targets to be made at once. The program
+.CW xstr ,
+for example,
+always modifies the files
+.CW strings
+and
+.CW x.c .
+There is no way to change it. Thus you cannot run two of them at once
+without something being trashed. Similarly, if you have commands
+in the makefile that always send output to the same file, you will not
+be able to make more than one target at once unless you change the
+file you use. You can, for instance, add a
+.CW $$$$
+to the end of the file name to tack on the process ID of the shell
+executing the command (each
+.CW $$
+expands to a single
+.CW $ ,
+thus giving you the shell variable
+.CW $$ ).
+Since only one shell is used for all the
+commands, you'll get the same file name for each command in the
+script.
+.LP
+The other problem comes from improperly-specified dependencies that
+worked in Make because of its sequential, depth-first way of examining
+them. While I don't want to go into depth on how PMake
+works (look in chapter 4 if you're interested), I will warn you that
+files in two different ``levels'' of the dependency tree may be
+examined in a different order in PMake than they were in Make. For
+example, given the makefile
+.DS
+a : b c
+b : d
+.DE
+PMake will examine the targets in the order
+.CW c ,
+.CW d ,
+.CW b ,
+.CW a .
+If the makefile's author expected PMake to abort before making
+.CW c
+if an error occurred while making
+.CW b ,
+or if
+.CW b
+needed to exist before
+.CW c
+was made,
+s/he will be sorely disappointed. The dependencies are
+incomplete, since in both these cases,
+.CW c
+would depend on
+.CW b .
+So watch out.
+.LP
+Another problem you may face is that, while PMake is set up to handle the
+output from multiple jobs in a graceful fashion, the same is not so for input.
+It has no way to regulate input to different jobs,
+so if you use the redirection from
+.CW /dev/tty
+I mentioned earlier, you must be careful not to run two of the jobs at once.
+.xH 2 Writing and Debugging a Makefile
+.LP
+Now you know most of what's in a makefile, what do you do next? There
+are two choices: (1) use one of the uncommonly-available makefile
+generators or (2) write your own makefile (I leave out the third choice of
+ignoring PMake and doing everything by hand as being beyond the bounds
+of common sense).
+.LP
+When faced with the writing of a makefile, it is usually best to start
+from first principles: just what
+.I are
+you trying to do? What do you want the makefile finally to produce?
+.LP
+To begin with a somewhat traditional example, let's say you need to
+write a makefile to create a program,
+.CW expr ,
+that takes standard infix expressions and converts them to prefix form (for
+no readily apparent reason). You've got three source files, in C, that
+make up the program:
+.CW main.c ,
+.CW parse.c ,
+and
+.CW output.c .
+Harking back to my pithy advice about dependency lines, you write the
+first line of the file:
+.DS
+expr : main.o parse.o output.o
+.DE
+because you remember
+.CW expr
+is made from
+.CW .o
+files, not
+.CW .c
+files. Similarly for the
+.CW .o
+files you produce the lines:
+.DS
+main.o : main.c
+parse.o : parse.c
+output.o : output.c
+main.o parse.o output.o : defs.h
+.DE
+.LP
+Great. You've now got the dependencies specified. What you need now is
+commands. These commands, remember, must produce the target on the
+dependency line, usually by using the sources you've listed.
+You remember about local variables? Good, so it should come
+to you as no surprise when you write
+.DS
+expr : main.o parse.o output.o
+ cc -o $(.TARGET) $(.ALLSRC)
+.DE
+Why use the variables? If your program grows to produce postfix
+expressions too (which, of course, requires a name change or two), it
+is one fewer place you have to change the file. You cannot do this for
+the object files, however, because they depend on their corresponding
+source files
+.I and
+.CW defs.h ,
+thus if you said
+.DS
+ cc -c $(.ALLSRC)
+.DE
+you'd get (for
+.CW main.o ):
+.DS
+ cc -c main.c defs.h
+.DE
+which is wrong. So you round out the makefile with these lines:
+.DS
+main.o : main.c
+ cc -c main.c
+parse.o : parse.c
+ cc -c parse.c
+output.o : output.c
+ cc -c output.c
+.DE
+.LP
+The makefile is now complete and will, in fact, create the program you
+want it to without unnecessary compilations or excessive typing on
+your part. There are two things wrong with it, however (aside from it
+being altogether too long, something I'll address in chapter 3):
+.IP 1)
+The string
+.CW "main.o parse.o output.o" '' ``
+is repeated twice, necessitating two changes when you add postfix
+(you were planning on that, weren't you?). This is in direct violation
+of de Boor's First Rule of writing makefiles:
+.QP
+.I
+Anything that needs to be written more than once
+should be placed in a variable.
+.IP "\&"
+I cannot emphasize this enough as being very important to the
+maintenance of a makefile and its program.
+.IP 2)
+There is no way to alter the way compilations are performed short of
+editing the makefile and making the change in all places. This is evil
+and violates de Boor's Second Rule, which follows directly from the
+first:
+.QP
+.I
+Any flags or programs used inside a makefile should be placed in a variable so
+they may be changed, temporarily or permanently, with the greatest ease.
+.LP
+The makefile should more properly read:
+.DS
+OBJS = main.o parse.o output.o
+expr : $(OBJS)
+ $(CC) $(CFLAGS) -o $(.TARGET) $(.ALLSRC)
+main.o : main.c
+ $(CC) $(CFLAGS) -c main.c
+parse.o : parse.c
+ $(CC) $(CFLAGS) -c parse.c
+output.o : output.c
+ $(CC) $(CFLAGS) -c output.c
+$(OBJS) : defs.h
+.DE
+Alternatively, if you like the idea of dynamic sources mentioned in
+section 2.3.1,
+.Rm 0 2.3.1
+.Rd 4
+.Ix 0 ref "dynamic source"
+.Ix 0 ref source dynamic
+you could write it like this:

+ $(CC) $(CFLAGS) -o $(.TARGET) $(.ALLSRC)
+$(OBJS) : $(.PREFIX).c defs.h

+These two rules and examples lead to de Boor's First Corollary:

+Variables are your friends.
+.LP
+Once you've written the makefile comes the sometimes-difficult task of
+.Ix 0 ref debugging
+making sure the darn thing works. Your most helpful tool to make sure
+the makefile is at least syntactically correct is the
+.B \-n
+.Ix 0 ref flags -n
+flag, which allows you to see if PMake will choke on the makefile. The
+second thing the
+.B \-n
+flag lets you do is see what PMake would do without it actually doing
+it, thus you can make sure the right commands would be executed were
+you to give PMake its head.
+.LP
+When you find your makefile isn't behaving as you hoped, the first
+question that comes to mind (after ``What time is it, anyway?'') is
+``Why not?'' In answering this, two flags will serve you well:
+.CW "-d m" '' ``
+.Ix 0 ref flags -d
+and
+.CW "-p 2" .'' ``
+.Ix 0 ref flags -p
+The first causes PMake to tell you as it examines each target in the
+makefile and indicate why it is deciding whatever it is deciding. You
+can then use the information printed for other targets to see where
+you went wrong. The
+.CW "-p 2" '' ``
+flag makes PMake print out its internal state when it is done,
+allowing you to see that you forgot to make that one chapter depend on
+that file of macros you just got a new version of. The output from
+.CW "-p 2" '' ``
+is intended to resemble closely a real makefile, but with additional
+information provided and with variables expanded in those commands
+PMake actually printed or executed.
+.LP
+Something to be especially careful about is circular dependencies.
+.Ix 0 def dependency circular
+E.g.
+.DS
+a : b
+b : c d
+d : a
+.DE
+In this case, because of how PMake works,
+.CW c
+is the only thing PMake will examine, because
+.CW d
+and
+.CW a
+will effectively fall off the edge of the universe, making it
+impossible to examine
+.CW b
+(or them, for that matter).
+PMake will tell you (if run in its normal mode) all the targets
+involved in any cycle it looked at (i.e. if you have two cycles in the
+graph (naughty, naughty), but only try to make a target in one of
+them, PMake will only tell you about that one. You'll have to try to
+make the other to find the second cycle). When run as Make, it will
+only print the first target in the cycle.
+.xH 2 Invoking PMake
+.LP
+.Ix 0 ref flags
+.Ix 0 ref arguments
+.Ix 0 ref usage
+PMake comes with a wide variety of flags to choose from.
+They may appear in any order, interspersed with command-line variable
+assignments and targets to create.
+The flags are as follows:
+.IP "\fB\-d\fP \fIwhat\fP"
+.Ix 0 def flags -d
+.Ix 0 ref debugging
+This causes PMake to spew out debugging information that
+may prove useful to you. If you can't
+figure out why PMake is doing what it's doing, you might try using
+this flag. The
+.I what
+parameter is a string of single characters that tell PMake what
+aspects you are interested in. Most of what I describe will make
+little sense to you, unless you've dealt with Make before. Just
+remember where this table is and come back to it as you read on.
+The characters and the information they produce are as follows:
+.RS
+.IP a
+Archive searching and caching.
+.IP c
+Conditional evaluation.
+.IP d
+The searching and caching of directories.
+.IP j
+Various snippets of information related to the running of the multiple
+shells. Not particularly interesting.
+.IP m
+The making of each target: what target is being examined; when it was
+last modified; whether it is out-of-date; etc.
+.IP p
+Makefile parsing.
+.IP r
+Remote execution.
+.IP s
+The application of suffix-transformation rules. (See chapter 3)
+.IP t
+The maintenance of the list of targets.
+.IP v
+Variable assignment.
+.RE
+.IP "\&"
+Of these all, the
+.CW m
+and
+.CW s
+letters will be most useful to you.
+If the
+.B \-d
+is the final argument or the argument from which it would get these
+key letters (see below for a note about which argument would be used)
+begins with a
+.B \- ,
+all of these debugging flags will be set, resulting in massive amounts
+of output.
+.IP "\fB\-f\fP \fImakefile\fP"
+.Ix 0 def flags -f
+Specify a makefile to read different from the standard makefiles
+.CW Makefile "\&" (
+or
+.CW makefile ).
+.Ix 0 ref makefile default
+.Ix 0 ref makefile other
+If
+.I makefile
+is ``\-'', PMake uses the standard input. This is useful for making
+quick and dirty makefiles.\|.\|.
+.Ix 0 ref makefile "quick and dirty"
+.IP \fB\-h\fP
+.Ix 0 def flags -h
+Prints out a summary of the various flags PMake accepts. It can also
+be used to find out what level of concurrency was compiled into the
+version of PMake you are using (look at
+.B \-J
+and
+.B \-L )
+and various other information on how PMake was configured.
+.Ix 0 ref configuration
+.Ix 0 ref makefile system
+.IP \fB\-i\fP
+.Ix 0 def flags -i
+If you give this flag, PMake will ignore non-zero status returned
+by any of its shells. It's like placing a `\-' before all the commands
+in the makefile.
+.IP \fB\-k\fP
+.Ix 0 def flags -k
+This is similar to
+.B \-i
+in that it allows PMake to continue when it sees an error, but unlike
+.B \-i ,
+where PMake continues blithely as if nothing went wrong,
+.B \-k
+causes it to recognize the error and only continue work on those
+things that don't depend on the target, either directly or indirectly (through
+depending on something that depends on it), whose creation returned the error.
+The `k' is for ``keep going''.\|.\|.
+.Ix 0 ref target
+.IP \fB\-l\fP
+.Ix 0 def flags -l
+PMake has the ability to lock a directory against other
+people executing it in the same directory (by means of a file called
+``LOCK.make'' that it creates and checks for in the directory). This
+is a Good Thing because two people doing the same thing in the same place
+can be disastrous for the final product (too many cooks and all that).
+Whether this locking is the default is up to your system
+administrator. If locking is on,
+.B \-l
+will turn it off, and vice versa. Note that this locking will not
+prevent \fIyou\fP from invoking PMake twice in the same place \*- if
+you own the lock file, PMake will warn you about it but continue to execute.
+.IP "\fB\-m\fP \fIdirectory\fP"
+.Ix 0 def flags -m
+Tells PMake another place to search for included makefiles via the <...>
+style. Several
+.B \-m
+options can be given to form a search path. If this construct is used the
+default system makefile search path is completely overridden.
+To be explained in chapter 3, section 3.2.
+.Rm 2 3.2
+.IP \fB\-n\fP
+.Ix 0 def flags -n
+This flag tells PMake not to execute the commands needed to update the
+out-of-date targets in the makefile. Rather, PMake will simply print
+the commands it would have executed and exit. This is particularly
+useful for checking the correctness of a makefile. If PMake doesn't do
+what you expect it to, it's a good chance the makefile is wrong.
+.IP "\fB\-p\fP \fInumber\fP"
+.Ix 0 def flags -p
+.Ix 0 ref debugging
+This causes PMake to print its input in a reasonable form, though
+not necessarily one that would make immediate sense to anyone but me. The
+.I number
+is a bitwise-or of 1 and 2 where 1 means it should print the input
+before doing any processing and 2 says it should print it after
+everything has been re-created. Thus
+.CW "\-p 3"
+would print it twice\*-once before processing and once after (you
+might find the difference between the two interesting). This is mostly
+useful to me, but you may find it informative in some bizarre circumstances.
+.IP \fB\-q\fP
+.Ix 0 def flags -q
+If you give PMake this flag, it will not try to re-create anything. It
+will just see if anything is out-of-date and exit non-zero if so.
+.IP \fB\-r\fP
+.Ix 0 def flags -r
+When PMake starts up, it reads a default makefile that tells it what
+sort of system it's on and gives it some idea of what to do if you
+don't tell it anything. I'll tell you about it in chapter 3. If you
+give this flag, PMake won't read the default makefile.
+.IP \fB\-s\fP
+.Ix 0 def flags -s
+This causes PMake to not print commands before they're executed. It
+is the equivalent of putting an `@' before every command in the
+makefile.
+.IP \fB\-t\fP
+.Ix 0 def flags -t
+Rather than try to re-create a target, PMake will simply ``touch'' it
+so as to make it appear up-to-date. If the target didn't exist before,
+it will when PMake finishes, but if the target did exist, it will
+appear to have been updated.
+.IP \fB\-v\fP
+.Ix 0 def flags -v
+This is a mixed-compatibility flag intended to mimic the System V
+version of Make. It is the same as giving
+.B \-B ,
+and
+.B \-V
+as well as turning off directory locking. Targets can still be created
+in parallel, however. This is the mode PMake will enter if it is
+invoked either as
+.CW smake '' ``
+or
+.CW vmake ''. ``
+.IP \fB\-x\fP
+.Ix 0 def flags -x
+This tells PMake it's ok to export jobs to other machines, if they're
+available. It is used when running in Make mode, as exporting in this
+mode tends to make things run slower than if the commands were just
+executed locally.
+.IP \fB\-B\fP
+.Ix 0 ref compatibility
+.Ix 0 def flags -B

+This is the flag that provides absolute, complete, full compatibility

+.Ix 0 def flags -P
+.Ix 0 ref "output control"
+When creating targets in parallel, several shells are executing at
+once, each wanting to write its own two cent's-worth to the screen.
+This output must be captured by PMake in some way in order to prevent
+the screen from being filled with garbage even more indecipherable
+than you usually see. PMake has two ways of doing this, one of which
+provides for much cleaner output and a clear separation between the
+output of different jobs, the other of which provides a more immediate
+response so one can tell what is really happening. The former is done
+by notifying you when the creation of a target starts, capturing the
+output and transferring it to the screen all at once when the job
+finishes. The latter is done by catching the output of the shell (and
+its children) and buffering it until an entire line is received, then
+printing that line preceded by an indication of which job produced
+the output. Since I prefer this second method, it is the one used by
+default. The first method will be used if you give the

+and would like PMake to stop bothering you. This flag tells it to shut

+A creation command is a regular shell command preceded by a tab. In

+whitespace) are a combination of
+.CW @ ' `
+or
+.CW - ', `
+PMake will cause the command to not be printed (if the character is

+.xH 1 Short-cuts and Other Nice Things
+.LP
+Based on what I've told you so far, you may have gotten the impression
+that PMake is just a way of storing away commands and making sure you
+don't forget to compile something. Good. That's just what it is.
+However, the ways I've described have been inelegant, at best, and
+painful, at worst.
+This chapter contains things that make the
+writing of makefiles easier and the makefiles themselves shorter and
+easier to modify (and, occasionally, simpler). In this chapter, I
+assume you are somewhat more
+familiar with Sprite (or UNIX, if that's what you're using) than I did
+in chapter 2, just so you're on your toes.
+So without further ado...
+.xH 2 Transformation Rules
+.LP
+As you know, a file's name consists of two parts: a base name, which
+gives some hint as to the contents of the file, and a suffix, which
+usually indicates the format of the file.
+Over the years, as
+.UX
+has developed,
+naming conventions, with regard to suffixes, have also developed that have
+become almost as incontrovertible as Law. E.g. a file ending in
+.CW .c
+is assumed to contain C source code; one with a
+.CW .o
+suffix is assumed to be a compiled, relocatable object file that may
+be linked into any program; a file with a
+.CW .ms
+suffix is usually a text file to be processed by Troff with the \-ms
+macro package, and so on.
+One of the best aspects of both Make and PMake comes from their
+understanding of how the suffix of a file pertains to its contents and
+their ability to do things with a file based solely on its suffix. This
+ability comes from something known as a transformation rule. A
+transformation rule specifies how to change a file with one suffix
+into a file with another suffix.
+.LP
+A transformation rule looks much like a dependency line, except the
+target is made of two known suffixes stuck together. Suffixes are made
+known to PMake by placing them as sources on a dependency line whose
+target is the special target
+.CW .SUFFIXES .
+E.g.
+.DS
+\&.SUFFIXES : .o .c
+\&.c.o :
+ $(CC) $(CFLAGS) -c $(.IMPSRC)
+.DE
+The creation script attached to the target is used to transform a file with
+the first suffix (in this case,
+.CW .c )
+into a file with the second suffix (here,
+.CW .o ).
+In addition, the target inherits whatever attributes have been applied
+to the transformation rule.
+The simple rule given above says that to transform a C source file
+into an object file, you compile it using
+.CW cc
+with the
+.CW \-c
+flag.
+This rule is taken straight from the system makefile. Many
+transformation rules (and suffixes) are defined there, and I refer you
+to it for more examples (type
+.CW "pmake -h" '' ``
+to find out where it is).
+.LP
+There are several things to note about the transformation rule given
+above:
+.RS
+.IP 1)
+The
+.CW .IMPSRC
+variable.
+.Ix 0 def variable local .IMPSRC
+.Ix 0 def .IMPSRC
+This variable is set to the ``implied source'' (the file from which
+the target is being created; the one with the first suffix), which, in this
+case, is the .c file.
+.IP 2)
+The
+.CW CFLAGS
+variable. Almost all of the transformation rules in the system
+makefile are set up using variables that you can alter in your
+makefile to tailor the rule to your needs. In this case, if you want
+all your C files to be compiled with the
+.B \-g
+flag, to provide information for
+.CW dbx ,
+you would set the
+.CW CFLAGS
+variable to contain
+.CW -g
+.CW "CFLAGS = -g" '') (``
+and PMake would take care of the rest.
+.RE
+.LP
+To give you a quick example, the makefile in 2.3.4
+.Rm 3 2.3.4
+could be changed to this:
+.DS
+OBJS = a.o b.o c.o
+program : $(OBJS)
+ $(CC) -o $(.TARGET) $(.ALLSRC)
+$(OBJS) : defs.h
+.DE
+The transformation rule I gave above takes the place of the 6 lines\**
+.FS
+This is also somewhat cleaner, I think, than the dynamic source
+solution presented in 2.6
+.FE
+.Rm 4 2.6
+.DS
+a.o : a.c
+ cc -c a.c
+b.o : b.c
+ cc -c b.c

+.LP
+Now you may be wondering about the dependency between the
+.CW .o
+and
+.CW .c
+files \*- it's not mentioned anywhere in the new makefile. This is
+because it isn't needed: one of the effects of applying a
+transformation rule is the target comes to depend on the implied
+source. That's why it's called the implied
+.I source .
+.LP
+For a more detailed example. Say you have a makefile like this:
+.DS
+a.out : a.o b.o
+ $(CC) $(.ALLSRC)
+.DE
+and a directory set up like this:

+sources for a target using transformation rules.
+The transformations it tries are, naturally
+enough, limited to the ones that have been defined (a transformation
+may be defined multiple times, by the way, but only the most recent
+one will be used). You will notice, however, that there is a definite
+order to the suffixes that are tried. This order is set by the
+relative positions of the suffixes on the
+.CW .SUFFIXES
+line \*- the earlier a suffix appears, the earlier it is checked as
+the source of a transformation. Once a suffix has been defined, the
+only way to change its position in the pecking order is to remove all
+the suffixes (by having a
+.CW .SUFFIXES
+dependency line with no sources) and redefine them in the order you
+want. (Previously-defined transformation rules will be automatically
+redefined as the suffixes they involve are re-entered.)
+.LP
+Another way to affect the search order is to make the dependency
+explicit. In the above example,
+.CW a.out
+depends on
+.CW a.o
+and
+.CW b.o .
+Since a transformation exists from
+.CW .o
+to
+.CW .out ,
+PMake uses that, as indicated by the
+.CW "using existing source a.o" '' ``
+message.
+.LP
+The search for a transformation starts from the suffix of the target
+and continues through all the defined transformations, in the order
+dictated by the suffix ranking, until an existing file with the same
+base (the target name minus the suffix and any leading directories) is
+found. At that point, one or more transformation rules will have been
+found to change the one existing file into the target.
+.LP
+For example, ignoring what's in the system makefile for now, say you
+have a makefile like this:
+.DS
+\&.SUFFIXES : .out .o .c .y .l
+\&.l.c :
+ lex $(.IMPSRC)
+ mv lex.yy.c $(.TARGET)
+\&.y.c :
+ yacc $(.IMPSRC)
+ mv y.tab.c $(.TARGET)
+\&.c.o :
+ cc -c $(.IMPSRC)
+\&.o.out :
+ cc -o $(.TARGET) $(.IMPSRC)
+.DE
+and the single file
+.CW jive.l .
+If you were to type
+.CW "pmake -rd ms jive.out" ,'' ``
+you would get the following output for
+.CW jive.out :
+.DS
+Suff_FindDeps (jive.out)
+ trying jive.o...not there
+ trying jive.c...not there
+ trying jive.y...not there
+ trying jive.l...got it
+ applying .l -> .c to "jive.l"
+ applying .c -> .o to "jive.c"
+ applying .o -> .out to "jive.o"
+.DE
+and this is why: PMake starts with the target
+.CW jive.out ,
+figures out its suffix
+.CW .out ) (
+and looks for things it can transform to a
+.CW .out
+file. In this case, it only finds
+.CW .o ,
+so it looks for the file
+.CW jive.o .
+It fails to find it, so it looks for transformations into a
+.CW .o
+file. Again it has only one choice:
+.CW .c .
+So it looks for
+.CW jive.c
+and, as you know, fails to find it. At this point it has two choices:
+it can create the
+.CW .c
+file from either a
+.CW .y
+file or a
+.CW .l
+file. Since
+.CW .y
+came first on the
+.CW .SUFFIXES
+line, it checks for
+.CW jive.y
+first, but can't find it, so it looks for
+.CW jive.l
+and, lo and behold, there it is.
+At this point, it has defined a transformation path as follows:
+.CW .l
+\(->
+.CW .c
+\(->
+.CW .o
+\(->
+.CW .out
+and applies the transformation rules accordingly. For completeness,
+and to give you a better idea of what PMake actually did with this
+three-step transformation, this is what PMake printed for the rest of
+the process:
+.DS
+Suff_FindDeps (jive.o)
+ using existing source jive.c
+ applying .c -> .o to "jive.c"
+Suff_FindDeps (jive.c)
+ using existing source jive.l
+ applying .l -> .c to "jive.l"
+Suff_FindDeps (jive.l)
+Examining jive.l...modified 17:16:01 Oct 4, 1987...up-to-date

+\&.\|.\|. meaningless lex output deleted .\|.\|.

+--- jive.o ---
+cc -c jive.c
+Examining jive.out...non-existent...out-of-date
+--- jive.out ---
+cc -o jive.out jive.o
+.DE
+.LP
+One final question remains: what does PMake do with targets that have
+no known suffix? PMake simply pretends it actually has a known suffix
+and searches for transformations accordingly.
+The suffix it chooses is the source for the
+.CW .NULL
+.Ix 0 ref .NULL
+target mentioned later. In the system makefile,
+.CW .out
+is chosen as the ``null suffix''
+.Ix 0 def suffix null
+.Ix 0 def "null suffix"
+because most people use PMake to create programs. You are, however,
+free and welcome to change it to a suffix of your own choosing.
+The null suffix is ignored, however, when PMake is in compatibility
+mode (see chapter 4).
+.xH 2 Including Other Makefiles
+.Ix 0 def makefile inclusion
+.Rd 2
+.LP
+Just as for programs, it is often useful to extract certain parts of a
+makefile into another file and just include it in other makefiles
+somehow. Many compilers allow you say something like
+.DS
+#include "defs.h"
+.DE
+to include the contents of
+.CW defs.h
+in the source file. PMake allows you to do the same thing for
+makefiles, with the added ability to use variables in the filenames.
+An include directive in a makefile looks either like this:
+.DS
+#include <file>
+.DE
+or this
+.DS
+#include "file"
+.DE
+The difference between the two is where PMake searches for the file:
+the first way, PMake will look for
+the file only in the system makefile directory (or directories)
+(to find out what that directory is, give PMake the
+.B \-h
+flag).
+.Ix 0 ref flags -h
+The system makefile directory search path can be overridden via the
+.B \-m
+option.
+.Ix 0 ref flags -m
+For files in double-quotes, the search is more complex:
+.RS
+.IP 1)
+The directory of the makefile that's including the file.
+.IP 2)
+The current directory (the one in which you invoked PMake).
+.IP 3)
+The directories given by you using
+.B \-I
+flags, in the order in which you gave them.
+.IP 4)
+Directories given by
+.CW .PATH
+dependency lines (see chapter 4).
+.IP 5)
+The system makefile directory.
+.RE
+.LP
+in that order.
+.LP
+You are free to use PMake variables in the filename\*-PMake will
+expand them before searching for the file. You must specify the
+searching method with either angle brackets or double-quotes
+.I outside
+of a variable expansion. I.e. the following
+.DS
+SYSTEM = <command.mk>
+
+#include $(SYSTEM)
+.DE
+won't work.
+.xH 2 Saving Commands
+.LP
+.Ix 0 def ...
+There may come a time when you will want to save certain commands to
+be executed when everything else is done. For instance: you're
+making several different libraries at one time and you want to create the
+members in parallel. Problem is,
+.CW ranlib
+is another one of those programs that can't be run more than once in
+the same directory at the same time (each one creates a file called
+.CW __.SYMDEF
+into which it stuffs information for the linker to use. Two of them
+running at once will overwrite each other's file and the result will
+be garbage for both parties). You might want a way to save the ranlib
+commands til the end so they can be run one after the other, thus
+keeping them from trashing each other's file. PMake allows you to do
+this by inserting an ellipsis (``.\|.\|.'') as a command between
+commands to be run at once and those to be run later.
+.LP
+So for the
+.CW ranlib
+case above, you might do this:
+.Rd 5
+.DS
+lib1.a : $(LIB1OBJS)
+ rm -f $(.TARGET)
+ ar cr $(.TARGET) $(.ALLSRC)
+ ...
+ ranlib $(.TARGET)
+
+lib2.a : $(LIB2OBJS)
+ rm -f $(.TARGET)
+ ar cr $(.TARGET) $(.ALLSRC)
+ ...
+ ranlib $(.TARGET)
+.DE
+.Ix 0 ref variable local .TARGET
+.Ix 0 ref variable local .ALLSRC
+This would save both
+.DS
+ranlib $(.TARGET)
+.DE
+commands until the end, when they would run one after the other
+(using the correct value for the
+.CW .TARGET
+variable, of course).
+.LP
+Commands saved in this manner are only executed if PMake manages to
+re-create everything without an error.
+.xH 2 Target Attributes
+.LP
+PMake allows you to give attributes to targets by means of special
+sources. Like everything else PMake uses, these sources begin with a
+period and are made up of all upper-case letters. There are various
+reasons for using them, and I will try to give examples for most of
+them. Others you'll have to find uses for yourself. Think of it as ``an
+exercise for the reader.'' By placing one (or more) of these as a source on a
+dependency line, you are ``marking the target(s) with that
+attribute.'' That's just the way I phrase it, so you know.
+.LP
+Any attributes given as sources for a transformation rule are applied
+to the target of the transformation rule when the rule is applied.
+.Ix 0 def attributes
+.Ix 0 ref source
+.Ix 0 ref target
+.nr pw 12
+.IP .DONTCARE \n(pw
+.Ix 0 def attributes .DONTCARE
+.Ix 0 def .DONTCARE
+If a target is marked with this attribute and PMake can't figure out
+how to create it, it will ignore this fact and assume the file isn't
+really needed or actually exists and PMake just can't find it. This may prove
+wrong, but the error will be noted later on, not when PMake tries to create
+the target so marked. This attribute also prevents PMake from
+attempting to touch the target if it is given the
+.B \-t
+flag.
+.Ix 0 ref flags -t
+.IP .EXEC \n(pw
+.Ix 0 def attributes .EXEC
+.Ix 0 def .EXEC
+This attribute causes its shell script to be executed while having no
+effect on targets that depend on it. This makes the target into a sort
+of subroutine. An example. Say you have some LISP files that need to
+be compiled and loaded into a LISP process. To do this, you echo LISP
+commands into a file and execute a LISP with this file as its input
+when everything's done. Say also that you have to load other files
+from another system before you can compile your files and further,
+that you don't want to go through the loading and dumping unless one
+of
+.I your
+files has changed. Your makefile might look a little bit
+like this (remember, this is an educational example, and don't worry
+about the
+.CW COMPILE
+rule, all will soon become clear, grasshopper):
+.DS
+system : init a.fasl b.fasl c.fasl
+ for i in $(.ALLSRC);
+ do
+ echo -n '(load "' >> input
+ echo -n ${i} >> input
+ echo '")' >> input
+ done
+ echo '(dump "$(.TARGET)")' >> input
+ lisp < input
+
+a.fasl : a.l init COMPILE
+b.fasl : b.l init COMPILE
+c.fasl : c.l init COMPILE
+COMPILE : .USE
+ echo '(compile "$(.ALLSRC)")' >> input
+init : .EXEC
+ echo '(load-system)' > input
+.DE
+.Ix 0 ref .USE
+.Ix 0 ref attributes .USE
+.Ix 0 ref variable local .ALLSRC
+.IP "\&"
+.CW .EXEC
+sources, don't appear in the local variables of targets that depend on
+them (nor are they touched if PMake is given the
+.B \-t
+flag).
+.Ix 0 ref flags -t
+Note that all the rules, not just that for
+.CW system ,
+include
+.CW init
+as a source. This is because none of the other targets can be made
+until
+.CW init
+has been made, thus they depend on it.
+.IP .EXPORT \n(pw
+.Ix 0 def attributes .EXPORT
+.Ix 0 def .EXPORT
+This is used to mark those targets whose creation should be sent to
+another machine if at all possible. This may be used by some
+exportation schemes if the exportation is expensive. You should ask
+your system administrator if it is necessary.
+.IP .EXPORTSAME \n(pw
+.Ix 0 def attributes .EXPORTSAME
+.Ix 0 def .EXPORTSAME
+Tells the export system that the job should be exported to a machine
+of the same architecture as the current one. Certain operations (e.g.
+running text through
+.CW nroff )
+can be performed the same on any architecture (CPU and
+operating system type), while others (e.g. compiling a program with
+.CW cc )
+must be performed on a machine with the same architecture. Not all
+export systems will support this attribute.
+.IP .IGNORE \n(pw
+.Ix 0 def attributes .IGNORE
+.Ix 0 def .IGNORE attribute
+Giving a target the
+.CW .IGNORE
+attribute causes PMake to ignore errors from any of the target's commands, as
+if they all had `\-' before them.
+.IP .INVISIBLE \n(pw
+.Ix 0 def attributes .INVISIBLE
+.Ix 0 def .INVISIBLE
+This allows you to specify one target as a source for another without
+the one affecting the other's local variables. Useful if, say, you
+have a makefile that creates two programs, one of which is used to
+create the other, so it must exist before the other is created. You
+could say
+.DS
+prog1 : $(PROG1OBJS) prog2 MAKEINSTALL
+prog2 : $(PROG2OBJS) .INVISIBLE MAKEINSTALL
+.DE
+where
+.CW MAKEINSTALL
+is some complex .USE rule (see below) that depends on the
+.Ix 0 ref .USE
+.CW .ALLSRC
+variable containing the right things. Without the
+.CW .INVISIBLE
+attribute for
+.CW prog2 ,
+the
+.CW MAKEINSTALL
+rule couldn't be applied. This is not as useful as it should be, and
+the semantics may change (or the whole thing go away) in the
+not-too-distant future.
+.IP .JOIN \n(pw
+.Ix 0 def attributes .JOIN
+.Ix 0 def .JOIN
+This is another way to avoid performing some operations in parallel
+while permitting everything else to be done so. Specifically it
+forces the target's shell script to be executed only if one or more of the
+sources was out-of-date. In addition, the target's name,
+in both its
+.CW .TARGET
+variable and all the local variables of any target that depends on it,
+is replaced by the value of its
+.CW .ALLSRC
+variable.
+As an example, suppose you have a program that has four libraries that
+compile in the same directory along with, and at the same time as, the
+program. You again have the problem with
+.CW ranlib
+that I mentioned earlier, only this time it's more severe: you
+can't just put the ranlib off to the end since the program
+will need those libraries before it can be re-created. You can do
+something like this:
+.DS
+program : $(OBJS) libraries
+ cc -o $(.TARGET) $(.ALLSRC)
+
+libraries : lib1.a lib2.a lib3.a lib4.a .JOIN
+ ranlib $(.OODATE)
+.DE
+.Ix 0 ref variable local .TARGET
+.Ix 0 ref variable local .ALLSRC
+.Ix 0 ref variable local .OODATE
+.Ix 0 ref .TARGET
+.Ix 0 ref .ALLSRC
+.Ix 0 ref .OODATE
+In this case, PMake will re-create the
+.CW $(OBJS)
+as necessary, along with
+.CW lib1.a ,
+.CW lib2.a ,
+.CW lib3.a
+and
+.CW lib4.a .
+It will then execute
+.CW ranlib
+on any library that was changed and set
+.CW program 's
+.CW .ALLSRC
+variable to contain what's in
+.CW $(OBJS)
+followed by
+.CW "lib1.a lib2.a lib3.a lib4.a" .'' ``
+In case you're wondering, it's called
+.CW .JOIN
+because it joins together different threads of the ``input graph'' at
+the target marked with the attribute.
+Another aspect of the .JOIN attribute is it keeps the target from
+being created if the
+.B \-t
+flag was given.
+.Ix 0 ref flags -t
+.IP .MAKE \n(pw
+.Ix 0 def attributes .MAKE
+.Ix 0 def .MAKE
+The
+.CW .MAKE
+attribute marks its target as being a recursive invocation of PMake.
+This forces PMake to execute the script associated with the target (if
+it's out-of-date) even if you gave the
+.B \-n
+or
+.B \-t
+flag. By doing this, you can start at the top of a system and type
+.DS
+pmake -n
+.DE
+and have it descend the directory tree (if your makefiles are set up
+correctly), printing what it would have executed if you hadn't
+included the
+.B \-n
+flag.
+.IP .NOEXPORT \n(pw
+.Ix 0 def attributes .NOEXPORT
+.Ix 0 def .NOEXPORT attribute
+If possible, PMake will attempt to export the creation of all targets to
+another machine (this depends on how PMake was configured). Sometimes,
+the creation is so simple, it is pointless to send it to another
+machine. If you give the target the
+.CW .NOEXPORT
+attribute, it will be run locally, even if you've given PMake the
+.B "\-L 0"
+flag.
+.IP .NOTMAIN \n(pw
+.Ix 0 def attributes .NOTMAIN
+.Ix 0 def .NOTMAIN
+Normally, if you do not specify a target to make in any other way,
+PMake will take the first target on the first dependency line of a
+makefile as the target to create. That target is known as the ``Main
+Target'' and is labeled as such if you print the dependencies out
+using the
+.B \-p
+flag.
+.Ix 0 ref flags -p
+Giving a target this attribute tells PMake that the target is
+definitely
+.I not
+the Main Target.
+This allows you to place targets in an included makefile and
+have PMake create something else by default.
+.IP .PRECIOUS \n(pw
+.Ix 0 def attributes .PRECIOUS
+.Ix 0 def .PRECIOUS attribute
+When PMake is interrupted (you type control-C at the keyboard), it
+will attempt to clean up after itself by removing any half-made
+targets. If a target has the
+.CW .PRECIOUS
+attribute, however, PMake will leave it alone. An additional side
+effect of the `::' operator is to mark the targets as
+.CW .PRECIOUS .
+.Ix 0 ref operator double-colon
+.Ix 0 ref ::
+.IP .SILENT \n(pw
+.Ix 0 def attributes .SILENT
+.Ix 0 def .SILENT attribute
+Marking a target with this attribute keeps its commands from being
+printed when they're executed, just as if they had an `@' in front of them.
+.IP .USE \n(pw
+.Ix 0 def attributes .USE
+.Ix 0 def .USE
+By giving a target this attribute, you turn it into PMake's equivalent
+of a macro. When the target is used as a source for another target,
+the other target acquires the commands, sources and attributes (except
+.CW .USE )
+of the source.
+If the target already has commands, the
+.CW .USE
+target's commands are added to the end. If more than one .USE-marked
+source is given to a target, the rules are applied sequentially.
+.IP "\&" \n(pw
+The typical .USE rule (as I call them) will use the sources of the
+target to which it is applied (as stored in the
+.CW .ALLSRC
+variable for the target) as its ``arguments,'' if you will.
+For example, you probably noticed that the commands for creating
+.CW lib1.a
+and
+.CW lib2.a
+in the example in section 3.3
+.Rm 5 3.3
+were exactly the same. You can use the
+.CW .USE
+attribute to eliminate the repetition, like so:
+.DS
+lib1.a : $(LIB1OBJS) MAKELIB
+lib2.a : $(LIB2OBJS) MAKELIB
+
+MAKELIB : .USE
+ rm -f $(.TARGET)
+ ar cr $(.TARGET) $(.ALLSRC)
+ ...
+ ranlib $(.TARGET)
+.DE
+.Ix 0 ref variable local .TARGET
+.Ix 0 ref variable local .ALLSRC
+.IP "\&" \n(pw
+Several system makefiles (not to be confused with The System Makefile)
+make use of these .USE rules to make your
+life easier (they're in the default, system makefile directory...take a look).
+Note that the .USE rule source itself
+.CW MAKELIB ) (
+does not appear in any of the targets's local variables.
+There is no limit to the number of times I could use the
+.CW MAKELIB
+rule. If there were more libraries, I could continue with
+.CW "lib3.a : $(LIB3OBJS) MAKELIB" '' ``
+and so on and so forth.
+.xH 2 Special Targets
+.LP
+As there were in Make, so there are certain targets that have special
+meaning to PMake. When you use one on a dependency line, it is the
+only target that may appear on the left-hand-side of the operator.
+.Ix 0 ref target
+.Ix 0 ref operator
+As for the attributes and variables, all the special targets
+begin with a period and consist of upper-case letters only.
+I won't describe them all in detail because some of them are rather
+complex and I'll describe them in more detail than you'll want in
+chapter 4.
+The targets are as follows:
+.nr pw 10
+.IP .BEGIN \n(pw
+.Ix 0 def .BEGIN
+Any commands attached to this target are executed before anything else
+is done. You can use it for any initialization that needs doing.
+.IP .DEFAULT \n(pw
+.Ix 0 def .DEFAULT
+This is sort of a .USE rule for any target (that was used only as a
+source) that PMake can't figure out any other way to create. It's only
+``sort of'' a .USE rule because only the shell script attached to the
+.CW .DEFAULT
+target is used. The
+.CW .IMPSRC
+variable of a target that inherits
+.CW .DEFAULT 's
+commands is set to the target's own name.
+.Ix 0 ref .IMPSRC
+.Ix 0 ref variable local .IMPSRC
+.IP .END \n(pw
+.Ix 0 def .END
+This serves a function similar to
+.CW .BEGIN ,
+in that commands attached to it are executed once everything has been
+re-created (so long as no errors occurred). It also serves the extra
+function of being a place on which PMake can hang commands you put off
+to the end. Thus the script for this target will be executed before
+any of the commands you save with the ``.\|.\|.''.
+.Ix 0 ref ...
+.IP .EXPORT \n(pw
+The sources for this target are passed to the exportation system compiled
+into PMake. Some systems will use these sources to configure
+themselves. You should ask your system administrator about this.
+.IP .IGNORE \n(pw
+.Ix 0 def .IGNORE target
+.Ix 0 ref .IGNORE attribute
+.Ix 0 ref attributes .IGNORE
+This target marks each of its sources with the
+.CW .IGNORE
+attribute. If you don't give it any sources, then it is like
+giving the
+.B \-i
+flag when you invoke PMake \*- errors are ignored for all commands.
+.Ix 0 ref flags -i
+.IP .INCLUDES \n(pw
+.Ix 0 def .INCLUDES target
+.Ix 0 def variable global .INCLUDES
+.Ix 0 def .INCLUDES variable
+The sources for this target are taken to be suffixes that indicate a
+file that can be included in a program source file.
+The suffix must have already been declared with
+.CW .SUFFIXES
+(see below).
+Any suffix so marked will have the directories on its search path
+(see
+.CW .PATH ,
+below) placed in the
+.CW .INCLUDES
+variable, each preceded by a
+.B \-I
+flag. This variable can then be used as an argument for the compiler
+in the normal fashion. The
+.CW .h
+suffix is already marked in this way in the system makefile.
+.Ix 0 ref makefile system
+E.g. if you have
+.DS
+\&.SUFFIXES : .bitmap
+\&.PATH.bitmap : /usr/local/X/lib/bitmaps
+\&.INCLUDES : .bitmap
+.DE
+PMake will place
+.CW "-I/usr/local/X/lib/bitmaps" '' ``
+in the
+.CW .INCLUDES
+variable and you can then say
+.DS
+cc $(.INCLUDES) -c xprogram.c
+.DE
+(Note: the
+.CW .INCLUDES
+variable is not actually filled in until the entire makefile has been read.)
+.IP .INTERRUPT \n(pw
+.Ix 0 def .INTERRUPT
+When PMake is interrupted,
+it will execute the commands in the script for this target, if it
+exists.
+.IP .LIBS \n(pw
+.Ix 0 def .LIBS target
+.Ix 0 def .LIBS variable
+.Ix 0 def variable global .LIBS
+This does for libraries what
+.CW .INCLUDES
+does for include files, except the flag used is
+.B \-L ,
+as required by those linkers that allow you to tell them where to find
+libraries. The variable used is
+.CW .LIBS .
+Be forewarned that PMake may not have been compiled to do this if the
+linker on your system doesn't accept the
+.B \-L
+flag, though the
+.CW .LIBS
+variable will always be defined once the makefile has been read.
+.IP .MAIN \n(pw
+.Ix 0 def .MAIN
+If you didn't give a target (or targets) to create when you invoked
+PMake, it will take the sources of this target as the targets to
+create.
+.IP .MAKEFLAGS \n(pw
+.Ix 0 def .MAKEFLAGS target
+This target provides a way for you to always specify flags for PMake
+when the makefile is used. The flags are just as they would be typed
+to the shell (except you can't use shell variables unless they're in
+the environment),
+though the
+.B \-f
+and
+.B \-r
+flags have no effect.
+.IP .NULL \n(pw
+.Ix 0 def .NULL
+.Ix 0 ref suffix null
+.Ix 0 ref "null suffix"
+This allows you to specify what suffix PMake should pretend a file has
+if, in fact, it has no known suffix. Only one suffix may be so
+designated. The last source on the dependency line is the suffix that
+is used (you should, however, only give one suffix.\|.\|.).
+.IP .PATH \n(pw
+.Ix 0 def .PATH
+If you give sources for this target, PMake will take them as
+directories in which to search for files it cannot find in the current
+directory. If you give no sources, it will clear out any directories
+added to the search path before. Since the effects of this all get
+very complex, I'll leave it til chapter four to give you a complete
+explanation.
+.IP .PATH\fIsuffix\fP \n(pw
+.Ix 0 ref .PATH
+This does a similar thing to
+.CW .PATH ,
+but it does it only for files with the given suffix. The suffix must
+have been defined already. Look at
+.B "Search Paths"
+(section 4.1)
+.Rm 6 4.1
+for more information.
+.IP .PRECIOUS \n(pw
+.Ix 0 def .PRECIOUS target
+.Ix 0 ref .PRECIOUS attribute
+.Ix 0 ref attributes .PRECIOUS
+Similar to
+.CW .IGNORE ,
+this gives the
+.CW .PRECIOUS

+.IP .SHELL \n(pw

+.IP .SILENT \n(pw
+.Ix 0 def .SILENT target
+.Ix 0 ref .SILENT attribute
+.Ix 0 ref attributes .SILENT
+When you use
+.CW .SILENT
+as a target, it applies the
+.CW .SILENT
+attribute to each of its sources. If there are no sources on the
+dependency line, then it is as if you gave PMake the
+.B \-s
+flag and no commands will be echoed.
+.IP .SUFFIXES \n(pw
+.Ix 0 def .SUFFIXES
+This is used to give new file suffixes for PMake to handle. Each
+source is a suffix PMake should recognize. If you give a

+suffixes it knew (this also nukes the null suffix).
+For those targets that need to have suffixes defined, this is how you do it.
+.LP
+In addition to these targets, a line of the form
+.DS
+\fIattribute\fP : \fIsources\fP
+.DE
+applies the
+.I attribute
+to all the targets listed as
+.I sources .
+.xH 2 Modifying Variable Expansion
+.LP
+.Ix 0 def variable expansion modified
+.Ix 0 ref variable expansion
+.Ix 0 def variable modifiers
+Variables need not always be expanded verbatim. PMake defines several
+modifiers that may be applied to a variable's value before it is
+expanded. You apply a modifier by placing it after the variable name
+with a colon between the two, like so:
+.DS
+${\fIVARIABLE\fP:\fImodifier\fP}
+.DE
+Each modifier is a single character followed by something specific to
+the modifier itself.
+You may apply as many modifiers as you want \*- each one is applied to
+the result of the previous and is separated from the previous by
+another colon.
+.LP
+There are seven ways to modify a variable's expansion, most of which
+come from the C shell variable modification characters:
+.RS
+.IP "M\fIpattern\fP"
+.Ix 0 def :M
+.Ix 0 def modifier match
+This is used to select only those words (a word is a series of
+characters that are neither spaces nor tabs) that match the given
+.I pattern .
+The pattern is a wildcard pattern like that used by the shell, where
+.CW *
+means 0 or more characters of any sort;
+.CW ?
+is any single character;
+.CW [abcd]
+matches any single character that is either `a', `b', `c' or `d'
+(there may be any number of characters between the brackets);
+.CW [0-9]
+matches any single character that is between `0' and `9' (i.e. any
+digit. This form may be freely mixed with the other bracket form), and
+`\\' is used to escape any of the characters `*', `?', `[' or `:',
+leaving them as regular characters to match themselves in a word.
+For example, the system makefile
+.CW <makedepend.mk>
+uses
+.CW "$(CFLAGS:M-[ID]*)" '' ``
+to extract all the
+.CW \-I
+and
+.CW \-D
+flags that would be passed to the C compiler. This allows it to
+properly locate include files and generate the correct dependencies.
+.IP "N\fIpattern\fP"
+.Ix 0 def :N
+.Ix 0 def modifier nomatch
+This is identical to
+.CW :M
+except it substitutes all words that don't match the given pattern.
+.IP "S/\fIsearch-string\fP/\fIreplacement-string\fP/[g]"
+.Ix 0 def :S
+.Ix 0 def modifier substitute
+Causes the first occurrence of
+.I search-string
+in the variable to be replaced by
+.I replacement-string ,
+unless the
+.CW g
+flag is given at the end, in which case all occurrences of the string
+are replaced. The substitution is performed on each word in the
+variable in turn. If
+.I search-string
+begins with a
+.CW ^ ,
+the string must match starting at the beginning of the word. If
+.I search-string
+ends with a
+.CW $ ,
+the string must match to the end of the word (these two may be
+combined to force an exact match). If a backslash precedes these two
+characters, however, they lose their special meaning. Variable
+expansion also occurs in the normal fashion inside both the
+.I search-string
+and the
+.I replacement-string ,
+.B except
+that a backslash is used to prevent the expansion of a
+.CW $ ,
+not another dollar sign, as is usual.
+Note that
+.I search-string
+is just a string, not a pattern, so none of the usual
+regular-expression/wildcard characters have any special meaning save
+.CW ^
+and
+.CW $ .
+In the replacement string,
+the
+.CW &
+character is replaced by the
+.I search-string
+unless it is preceded by a backslash.
+You are allowed to use any character except
+colon or exclamation point to separate the two strings. This so-called
+delimiter character may be placed in either string by preceding it
+with a backslash.
+.IP T
+.Ix 0 def :T
+.Ix 0 def modifier tail
+Replaces each word in the variable expansion by its last
+component (its ``tail''). For example, given
+.DS
+OBJS = ../lib/a.o b /usr/lib/libm.a
+TAILS = $(OBJS:T)
+.DE
+the variable
+.CW TAILS
+would expand to
+.CW "a.o b libm.a" .'' ``
+.IP H
+.Ix 0 def :H
+.Ix 0 def modifier head
+This is similar to
+.CW :T ,
+except that every word is replaced by everything but the tail (the
+``head''). Using the same definition of
+.CW OBJS ,
+the string
+.CW "$(OBJS:H)" '' ``
+would expand to
+.CW "../lib /usr/lib" .'' ``
+Note that the final slash on the heads is removed and
+anything without a head is replaced by the empty string.
+.IP E
+.Ix 0 def :E
+.Ix 0 def modifier extension
+.Ix 0 def modifier suffix
+.Ix 0 ref suffix "variable modifier"
+.CW :E
+replaces each word by its suffix (``extension''). So
+.CW "$(OBJS:E)" '' ``
+would give you
+.CW ".o .a" .'' ``
+.IP R
+.Ix 0 def :R
+.Ix 0 def modifier root
+.Ix 0 def modifier base
+This replaces each word by everything but the suffix (the ``root'' of
+the word).
+.CW "$(OBJS:R)" '' ``
+expands to ``
+.CW "../lib/a b /usr/lib/libm" .''
+.RE
+.LP
+In addition, the System V style of substitution is also supported.
+This looks like:
+.DS
+$(\fIVARIABLE\fP:\fIsearch-string\fP=\fIreplacement\fP)
+.DE
+It must be the last modifier in the chain. The search is anchored at
+the end of each word, so only suffixes or whole words may be replaced.
+.xH 2 More on Debugging
+.xH 2 More Exercises
+.IP (3.1)
+You've got a set programs, each of which is created from its own
+assembly-language source file (suffix
+.CW .asm ).
+Each program can be assembled into two versions, one with error-checking
+code assembled in and one without. You could assemble them into files
+with different suffixes
+.CW .eobj \& (
+and
+.CW .obj ,
+for instance), but your linker only understands files that end in
+.CW .obj .
+To top it all off, the final executables
+.I must
+have the suffix
+.CW .exe .
+How can you still use transformation rules to make your life easier
+(Hint: assume the error-checking versions have
+.CW ec
+tacked onto their prefix)?
+.IP (3.2)
+Assume, for a moment or two, you want to perform a sort of
+``indirection'' by placing the name of a variable into another one,
+then you want to get the value of the first by expanding the second
+somehow. Unfortunately, PMake doesn't allow constructs like
+.DS I
+$($(FOO))
+.DE
+What do you do? Hint: no further variable expansion is performed after
+modifiers are applied, thus if you cause a $ to occur in the
+expansion, that's what will be in the result.
+.xH 1 PMake for Gods
+.LP
+This chapter is devoted to those facilities in PMake that allow you to
+do a great deal in a makefile with very little work, as well as do
+some things you couldn't do in Make without a great deal of work (and
+perhaps the use of other programs). The problem with these features,
+is they must be handled with care, or you will end up with a mess.
+.LP
+Once more, I assume a greater familiarity with
+.UX
+or Sprite than I did in the previous two chapters.
+.xH 2 Search Paths
+.Rd 6
+.LP
+PMake supports the dispersal of files into multiple directories by
+allowing you to specify places to look for sources with
+.CW .PATH
+targets in the makefile. The directories you give as sources for these
+targets make up a ``search path.'' Only those files used exclusively
+as sources are actually sought on a search path, the assumption being
+that anything listed as a target in the makefile can be created by the
+makefile and thus should be in the current directory.
+.LP
+There are two types of search paths
+in PMake: one is used for all types of files (including included
+makefiles) and is specified with a plain
+.CW .PATH
+target (e.g.
+.CW ".PATH : RCS" ''), ``
+while the other is specific to a certain type of file, as indicated by
+the file's suffix. A specific search path is indicated by immediately following
+the
+.CW .PATH
+with the suffix of the file. For instance
+.DS
+\&.PATH.h : /sprite/lib/include /sprite/att/lib/include
+.DE
+would tell PMake to look in the directories
+.CW /sprite/lib/include
+and
+.CW /sprite/att/lib/include
+for any files whose suffix is
+.CW .h .
+.LP
+The current directory is always consulted first to see if a file
+exists. Only if it cannot be found there are the directories in the
+specific search path, followed by those in the general search path,
+consulted.
+.LP
+A search path is also used when expanding wildcard characters. If the
+pattern has a recognizable suffix on it, the path for that suffix will
+be used for the expansion. Otherwise the default search path is employed.
+.LP
+When a file is found in some directory other than the current one, all
+local variables that would have contained the target's name
+.CW .ALLSRC , (
+and
+.CW .IMPSRC )
+will instead contain the path to the file, as found by PMake.
+Thus if you have a file
+.CW ../lib/mumble.c
+and a makefile
+.DS
+\&.PATH.c : ../lib
+mumble : mumble.c
+ $(CC) -o $(.TARGET) $(.ALLSRC)
+.DE
+the command executed to create
+.CW mumble
+would be
+.CW "cc -o mumble ../lib/mumble.c" .'' ``
+(As an aside, the command in this case isn't strictly necessary, since
+it will be found using transformation rules if it isn't given. This is because
+.CW .out
+is the null suffix by default and a transformation exists from
+.CW .c
+to
+.CW .out .
+Just thought I'd throw that in.)
+.LP
+If a file exists in two directories on the same search path, the file
+in the first directory on the path will be the one PMake uses. So if
+you have a large system spread over many directories, it would behoove
+you to follow a naming convention that avoids such conflicts.
+.LP
+Something you should know about the way search paths are implemented
+is that each directory is read, and its contents cached, exactly once
+\&\*- when it is first encountered \*- so any changes to the
+directories while PMake is running will not be noted when searching
+for implicit sources, nor will they be found when PMake attempts to
+discover when the file was last modified, unless the file was created in the
+current directory. While people have suggested that PMake should read
+the directories each time, my experience suggests that the caching seldom
+causes problems. In addition, not caching the directories slows things
+down enormously because of PMake's attempts to apply transformation
+rules through non-existent files \*- the number of extra file-system
+searches is truly staggering, especially if many files without
+suffixes are used and the null suffix isn't changed from
+.CW .out .
+.xH 2 Archives and Libraries
+.LP
+.UX
+and Sprite allow you to merge files into an archive using the
+.CW ar
+command. Further, if the files are relocatable object files, you can
+run
+.CW ranlib
+on the archive and get yourself a library that you can link into any
+program you want. The main problem with archives is they double the
+space you need to store the archived files, since there's one copy in
+the archive and one copy out by itself. The problem with libraries is
+you usually think of them as
+.CW -lm
+rather than
+.CW /usr/lib/libm.a
+and the linker thinks they're out-of-date if you so much as look at
+them.
+.LP
+PMake solves the problem with archives by allowing you to tell it to
+examine the files in the archives (so you can remove the individual
+files without having to regenerate them later). To handle the problem
+with libraries, PMake adds an additional way of deciding if a library
+is out-of-date:
+.IP \(bu 2
+If the table of contents is older than the library, or is missing, the
+library is out-of-date.
+.LP
+A library is any target that looks like
+.CW \-l name'' ``
+or that ends in a suffix that was marked as a library using the
+.CW .LIBS
+target.
+.CW .a
+is so marked in the system makefile.
+.LP
+Members of an archive are specified as
+``\fIarchive\fP(\fImember\fP[ \fImember\fP...])''.
+Thus
+.CW libdix.a(window.o) '' ``'
+specifies the file
+.CW window.o
+in the archive
+.CW libdix.a .
+You may also use wildcards to specify the members of the archive. Just
+remember that most the wildcard characters will only find
+.I existing
+files.
+.LP
+A file that is a member of an archive is treated specially. If the
+file doesn't exist, but it is in the archive, the modification time
+recorded in the archive is used for the file when determining if the
+file is out-of-date. When figuring out how to make an archived member target
+(not the file itself, but the file in the archive \*- the
+\fIarchive\fP(\fImember\fP) target), special care is
+taken with the transformation rules, as follows:
+.IP \(bu 2
+\&\fIarchive\fP(\fImember\fP) is made to depend on \fImember\fP.
+.IP \(bu 2
+The transformation from the \fImember\fP's suffix to the
+\fIarchive\fP's suffix is applied to the \fIarchive\fP(\fImember\fP) target.
+.IP \(bu 2
+The \fIarchive\fP(\fImember\fP)'s
+.CW .TARGET
+variable is set to the name of the \fImember\fP if \fImember\fP is
+actually a target, or the path to the member file if \fImember\fP is
+only a source.
+.IP \(bu 2
+The
+.CW .ARCHIVE
+variable for the \fIarchive\fP(\fImember\fP) target is set to the name
+of the \fIarchive\fP.
+.Ix 0 def variable local .ARCHIVE
+.Ix 0 def .ARCHIVE
+.IP \(bu 2
+The
+.CW .MEMBER
+variable is set to the actual string inside the parentheses. In most
+cases, this will be the same as the
+.CW .TARGET
+variable.
+.Ix 0 def variable local .MEMBER
+.Ix 0 def .MEMBER
+.IP \(bu 2
+The \fIarchive\fP(\fImember\fP)'s place in the local variables of the
+targets that depend on it is taken by the value of its
+.CW .TARGET
+variable.
+.LP
+Thus, a program library could be created with the following makefile:
+.DS
+\&.o.a :
+ ...
+ rm -f $(.TARGET:T)
+OBJS = obj1.o obj2.o obj3.o
+libprog.a : libprog.a($(OBJS))
+ ar cru $(.TARGET) $(.OODATE)
+ ranlib $(.TARGET)
+.DE
+This will cause the three object files to be compiled (if the
+corresponding source files were modified after the object file or, if
+that doesn't exist, the archived object file), the out-of-date ones
+archived in
+.CW libprog.a ,
+a table of contents placed in the archive and the newly-archived
+object files to be removed.
+.LP
+All this is used in the
+.CW makelib.mk
+system makefile to create a single library with ease. This makefile
+looks like this:
+.DS
+.SM
+#
+# Rules for making libraries. The object files that make up the library
+# are removed once they are archived.
+#
+# To make several libraries in parallel, you should define the variable
+# "many_libraries". This will serialize the invocations of ranlib.
+#
+# To use, do something like this:
+#
+# OBJECTS = <files in the library>
+#
+# fish.a: fish.a($(OBJECTS)) MAKELIB
+#
+#
+
+#ifndef _MAKELIB_MK
+_MAKELIB_MK =
+
+#include <po.mk>
+
+\&.po.a .o.a :
+ ...
+ rm -f $(.MEMBER)
+
+ARFLAGS ?= crl
+
+#
+# Re-archive the out-of-date members and recreate the library's table of
+# contents using ranlib. If many_libraries is defined, put the ranlib
+# off til the end so many libraries can be made at once.
+#
+MAKELIB : .USE .PRECIOUS

+#endif /* no_ranlib */
+
+#endif /* _MAKELIB_MK */
+.DE
+.xH 2 On the Condition...
+.Rd 1
+.LP
+Like the C compiler before it, PMake allows you to configure the makefile,
+based on the current environment, using conditional statements. A
+conditional looks like this:
+.DS
+#if \fIboolean expression\fP
+\fIlines\fP
+#elif \fIanother boolean expression\fP
+\fImore lines\fP
+#else
+\fIstill more lines\fP
+#endif
+.DE
+They may be nested to a maximum depth of 30 and may occur anywhere
+(except in a comment, of course). The
+.CW # '' ``
+must the very first character on the line.
+.LP
+Each
+.I "boolean expression"
+is made up of terms that look like function calls, the standard C
+boolean operators
+.CW && ,
+.CW || ,
+and
+.CW ! ,
+and the standard relational operators
+.CW == ,
+.CW != ,
+.CW > ,
+.CW >= ,
+.CW < ,
+and
+.CW <= ,
+with
+.CW ==
+and
+.CW !=
+being overloaded to allow string comparisons as well.
+.CW &&
+represents logical AND;
+.CW ||
+is logical OR and
+.CW !
+is logical NOT. The arithmetic and string operators take precedence
+over all three of these operators, while NOT takes precedence over
+AND, which takes precedence over OR. This precedence may be
+overridden with parentheses, and an expression may be parenthesized to
+your heart's content. Each term looks like a call on one of four
+functions:
+.nr pw 9
+.Ix 0 def make
+.Ix 0 def conditional make
+.Ix 0 def if make
+.IP make \n(pw
+The syntax is
+.CW make( \fItarget\fP\c
+.CW )
+where
+.I target
+is a target in the makefile. This is true if the given target was
+specified on the command line, or as the source for a
+.CW .MAIN
+target (note that the sources for
+.CW .MAIN
+are only used if no targets were given on the command line).
+.IP defined \n(pw
+.Ix 0 def defined
+.Ix 0 def conditional defined
+.Ix 0 def if defined
+The syntax is
+.CW defined( \fIvariable\fP\c
+.CW )
+and is true if
+.I variable
+is defined. Certain variables are defined in the system makefile that
+identify the system on which PMake is being run.
+.IP exists \n(pw
+.Ix 0 def exists
+.Ix 0 def conditional exists
+.Ix 0 def if exists
+The syntax is
+.CW exists( \fIfile\fP\c
+.CW )
+and is true if the file can be found on the global search path
+(i.e. that defined by
+.CW .PATH
+targets, not by
+.CW .PATH \fIsuffix\fP
+targets).
+.IP empty \n(pw
+.Ix 0 def empty
+.Ix 0 def conditional empty
+.Ix 0 def if empty
+This syntax is much like the others, except the string inside the
+parentheses is of the same form as you would put between parentheses
+when expanding a variable, complete with modifiers and everything. The
+function returns true if the resulting string is empty (NOTE: an undefined
+variable in this context will cause at the very least a warning
+message about a malformed conditional, and at the worst will cause the
+process to stop once it has read the makefile. If you want to check
+for a variable being defined or empty, use the expression
+.CW !defined( \fIvar\fP\c ``
+.CW ") || empty(" \fIvar\fP\c
+.CW ) ''
+as the definition of
+.CW ||
+will prevent the
+.CW empty()
+from being evaluated and causing an error, if the variable is
+undefined). This can be used to see if a variable contains a given
+word, for example:
+.DS
+#if !empty(\fIvar\fP:M\fIword\fP)
+.DE
+.LP
+The arithmetic and string operators may only be used to test the value
+of a variable. The lefthand side must contain the variable expansion,
+while the righthand side contains either a string, enclosed in
+double-quotes, or a number. The standard C numeric conventions (except
+for specifying an octal number) apply to both sides. E.g.
+.DS
+#if $(OS) == 4.3
+
+#if $(MACHINE) == "sun3"
+
+#if $(LOAD_ADDR) < 0xc000
+.DE
+are all valid conditionals. In addition, the numeric value of a
+variable can be tested as a boolean as follows:
+.DS
+#if $(LOAD)
+.DE
+would see if
+.CW LOAD
+contains a non-zero value and
+.DS
+#if !$(LOAD)
+.DE
+would test if
+.CW LOAD
+contains a zero value.
+.LP
+In addition to the bare
+.CW #if ,'' ``
+there are other forms that apply one of the first two functions to each
+term. They are as follows:
+.DS
+ ifdef \fRdefined\fP
+ ifndef \fR!defined\fP
+ ifmake \fRmake\fP
+ ifnmake \fR!make\fP
+.DE
+There are also the ``else if'' forms:
+.CW elif ,
+.CW elifdef ,
+.CW elifndef ,
+.CW elifmake ,
+and
+.CW elifnmake .
+.LP
+For instance, if you wish to create two versions of a program, one of which
+is optimized (the production version) and the other of which is for debugging
+(has symbols for dbx), you have two choices: you can create two
+makefiles, one of which uses the
+.CW \-g
+flag for the compilation, while the other uses the
+.CW \-O
+flag, or you can use another target (call it
+.CW debug )
+to create the debug version. The construct below will take care of
+this for you. I have also made it so defining the variable
+.CW DEBUG
+(say with
+.CW "pmake -D DEBUG" )
+will also cause the debug version to be made.
+.DS
+#if defined(DEBUG) || make(debug)
+CFLAGS += -g
+#else
+CFLAGS += -O
+#endif
+.DE
+There are, of course, problems with this approach. The most glaring
+annoyance is that if you want to go from making a debug version to
+making a production version, you have to remove all the object files,
+or you will get some optimized and some debug versions in the same
+program. Another annoyance is you have to be careful not to make two
+targets that ``conflict'' because of some conditionals in the
+makefile. For instance
+.DS
+#if make(print)
+FORMATTER = ditroff -Plaser_printer
+#endif
+#if make(draft)
+FORMATTER = nroff -Pdot_matrix_printer
+#endif
+.DE
+would wreak havoc if you tried
+.CW "pmake draft print" '' ``
+since you would use the same formatter for each target. As I said,
+this all gets somewhat complicated.
+.xH 2 A Shell is a Shell is a Shell
+.Rd 7
+.LP
+In normal operation, the Bourne Shell (better known as
+.CW sh '') ``
+is used to execute the commands to re-create targets. PMake also allows you
+to specify a different shell for it to use when executing these
+commands. There are several things PMake must know about the shell you
+wish to use. These things are specified as the sources for the
+.CW .SHELL
+.Ix 0 ref .SHELL
+.Ix 0 ref target .SHELL
+target by keyword, as follows:
+.IP "\fBpath=\fP\fIpath\fP"
+PMake needs to know where the shell actually resides, so it can
+execute it. If you specify this and nothing else, PMake will use the
+last component of the path and look in its table of the shells it
+knows and use the specification it finds, if any. Use this if you just
+want to use a different version of the Bourne or C Shell (yes, PMake knows
+how to use the C Shell too).
+.IP "\fBname=\fP\fIname\fP"
+This is the name by which the shell is to be known. It is a single
+word and, if no other keywords are specified (other than
+.B path ),
+it is the name by which PMake attempts to find a specification for
+it (as mentioned above). You can use this if you would just rather use
+the C Shell than the Bourne Shell
+.CW ".SHELL: name=csh" '' (``
+will do it).
+.IP "\fBquiet=\fP\fIecho-off command\fP"
+As mentioned before, PMake actually controls whether commands are
+printed by introducing commands into the shell's input stream. This
+keyword, and the next two, control what those commands are. The
+.B quiet
+keyword is the command used to turn echoing off. Once it is turned
+off, echoing is expected to remain off until the echo-on command is given.
+.IP "\fBecho=\fP\fIecho-on command\fP"
+The command PMake should give to turn echoing back on again.
+.IP "\fBfilter=\fP\fIprinted echo-off command\fP"
+Many shells will echo the echo-off command when it is given. This
+keyword tells PMake in what format the shell actually prints the
+echo-off command. Wherever PMake sees this string in the shell's
+output, it will delete it and any following whitespace, up to and
+including the next newline. See the example at the end of this section
+for more details.
+.IP "\fBechoFlag=\fP\fIflag to turn echoing on\fP"
+Unless a target has been marked
+.CW .SILENT ,
+PMake wants to start the shell running with echoing on. To do this, it
+passes this flag to the shell as one of its arguments. If either this
+or the next flag begins with a `\-', the flags will be passed to the
+shell as separate arguments. Otherwise, the two will be concatenated
+(if they are used at the same time, of course).
+.IP "\fBerrFlag=\fP\fIflag to turn error checking on\fP"
+Likewise, unless a target is marked
+.CW .IGNORE ,
+PMake wishes error-checking to be on from the very start. To this end,
+it will pass this flag to the shell as an argument. The same rules for
+an initial `\-' apply as for the
+.B echoFlag .
+.IP "\fBcheck=\fP\fIcommand to turn error checking on\fP"
+Just as for echo-control, error-control is achieved by inserting
+commands into the shell's input stream. This is the command to make
+the shell check for errors. It also serves another purpose if the
+shell doesn't have error-control as commands, but I'll get into that
+in a minute. Again, once error checking has been turned on, it is
+expected to remain on until it is turned off again.
+.IP "\fBignore=\fP\fIcommand to turn error checking off\fP"
+This is the command PMake uses to turn error checking off. It has
+another use if the shell doesn't do error-control, but I'll tell you
+about that.\|.\|.\|now.
+.IP "\fBhasErrCtl=\fP\fIyes or no\fP"
+This takes a value that is either
+.B yes
+or
+.B no .
+Now you might think that the existence of the
+.B check
+and
+.B ignore
+keywords would be enough to tell PMake if the shell can do
+error-control, but you'd be wrong. If
+.B hasErrCtl
+is
+.B yes ,
+PMake uses the check and ignore commands in a straight-forward manner.
+If this is
+.B no ,
+however, their use is rather different. In this case, the check
+command is used as a template, in which the string
+.B %s
+is replaced by the command that's about to be executed, to produce a
+command for the shell that will echo the command to be executed. The
+ignore command is also used as a template, again with
+.B %s
+replaced by the command to be executed, to produce a command that will
+execute the command to be executed and ignore any error it returns.
+When these strings are used as templates, you must provide newline(s)
+.CW \en '') (``
+in the appropriate place(s).
+.LP
+The strings that follow these keywords may be enclosed in single or
+double quotes (the quotes will be stripped off) and may contain the
+usual C backslash-characters (\en is newline, \er is return, \eb is
+backspace, \e' escapes a single-quote inside single-quotes, \e"
+escapes a double-quote inside double-quotes). Now for an example.
+.LP
+This is actually the contents of the
+.CW <shx.mk>
+system makefile, and causes PMake to use the Bourne Shell in such a
+way that each command is printed as it is executed. That is, if more
+than one command is given on a line, each will be printed separately.
+Similarly, each time the body of a loop is executed, the commands
+within that loop will be printed, etc. The specification runs like
+this:
+.DS
+#
+# This is a shell specification to have the Bourne shell echo
+# the commands just before executing them, rather than when it reads
+# them. Useful if you want to see how variables are being expanded, etc.
+#
+\&.SHELL : path=/bin/sh \e
+ quiet="set -" \e
+ echo="set -x" \e
+ filter="+ set - " \e
+ echoFlag=x \e
+ errFlag=e \e
+ hasErrCtl=yes \e
+ check="set -e" \e
+ ignore="set +e"
+.DE
+.LP
+It tells PMake the following:
+.Bp
+The shell is located in the file
+.CW /bin/sh .
+It need not tell PMake that the name of the shell is
+.CW sh
+as PMake can figure that out for itself (it's the last component of
+the path).
+.Bp
+The command to stop echoing is
+.CW "set -" .
+.Bp
+The command to start echoing is
+.CW "set -x" .
+.Bp
+When the echo off command is executed, the shell will print
+.CW "+ set - "
+(The `+' comes from using the
+.CW \-x
+flag (rather than the
+.CW \-v
+flag PMake usually uses)). PMake will remove all occurrences of this
+string from the output, so you don't notice extra commands you didn't
+put there.
+.Bp
+The flag the Bourne Shell will take to start echoing in this way is
+the
+.CW \-x
+flag. The Bourne Shell will only take its flag arguments concatenated
+as its first argument, so neither this nor the
+.B errFlag
+specification begins with a \-.
+.Bp
+The flag to use to turn error-checking on from the start is
+.CW \-e .
+.Bp
+The shell can turn error-checking on and off, and the commands to do
+so are
+.CW "set +e"
+and
+.CW "set -e" ,
+respectively.
+.LP
+I should note that this specification is for Bourne Shells that are
+not part of Berkeley
+.UX ,
+as shells from Berkeley don't do error control. You can get a similar
+effect, however, by changing the last three lines to be:
+.DS
+ hasErrCtl=no \e
+ check="echo \e"+ %s\e"\en" \e
+ ignore="sh -c '%s || exit 0\en"
+.DE
+.LP
+This will cause PMake to execute the two commands
+.DS
+echo "+ \fIcmd\fP"
+sh -c '\fIcmd\fP || true'
+.DE
+for each command for which errors are to be ignored. (In case you are
+wondering, the thing for
+.CW ignore
+tells the shell to execute another shell without error checking on and
+always exit 0, since the
+.B ||
+causes the
+.CW "exit 0"
+to be executed only if the first command exited non-zero, and if the
+first command exited zero, the shell will also exit zero, since that's
+the last command it executed).
+.xH 2 Compatibility
+.Ix 0 ref compatibility
+.LP
+There are three (well, 3 \(12) levels of backwards-compatibility built
+into PMake. Most makefiles will need none at all. Some may need a
+little bit of work to operate correctly when run in parallel. Each
+level encompasses the previous levels (e.g.
+.B \-B
+(one shell per command) implies
+.B \-V )
+The three levels are described in the following three sections.
+.xH 3 DEFCON 3 \*- Variable Expansion
+.Ix 0 ref compatibility
+.LP
+As noted before, PMake will not expand a variable unless it knows of a
+value for it. This can cause problems for makefiles that expect to
+leave variables undefined except in special circumstances (e.g. if
+more flags need to be passed to the C compiler or the output from a
+text processor should be sent to a different printer). If the
+variables are enclosed in curly braces
+.CW ${PRINTER} ''), (``
+the shell will let them pass. If they are enclosed in parentheses,
+however, the shell will declare a syntax error and the make will come
+to a grinding halt.
+.LP
+You have two choices: change the makefile to define the variables
+(their values can be overridden on the command line, since that's
+where they would have been set if you used Make, anyway) or always give the
+.B \-V
+flag (this can be done with the
+.CW .MAKEFLAGS
+target, if you want).
+.xH 3 DEFCON 2 \*- The Number of the Beast
+.Ix 0 ref compatibility
+.LP
+Then there are the makefiles that expect certain commands, such as
+changing to a different directory, to not affect other commands in a
+target's creation script. You can solve this is either by going
+back to executing one shell per command (which is what the
+.B \-B
+flag forces PMake to do), which slows the process down a good bit and
+requires you to use semicolons and escaped newlines for shell constructs, or
+by changing the makefile to execute the offending command(s) in a subshell
+(by placing the line inside parentheses), like so:
+.DS
+install :: .MAKE
+ (cd src; $(.PMAKE) install)
+ (cd lib; $(.PMAKE) install)
+ (cd man; $(.PMAKE) install)
+.DE
+.Ix 0 ref operator double-colon
+.Ix 0 ref variable global .PMAKE
+.Ix 0 ref .PMAKE
+.Ix 0 ref .MAKE
+.Ix 0 ref attribute .MAKE
+This will always execute the three makes (even if the
+.B \-n
+flag was given) because of the combination of the ``::'' operator and
+the
+.CW .MAKE
+attribute. Each command will change to the proper directory to perform
+the install, leaving the main shell in the directory in which it started.
+.xH 3 "DEFCON 1 \*- Imitation is the Not the Highest Form of Flattery"
+.Ix 0 ref compatibility
+.LP
+The final category of makefile is the one where every command requires
+input, the dependencies are incompletely specified, or you simply
+cannot create more than one target at a time, as mentioned earlier. In
+addition, you may not have the time or desire to upgrade the makefile
+to run smoothly with PMake. If you are the conservative sort, this is
+the compatibility mode for you. It is entered either by giving PMake
+the
+.B \-M
+flag (for Make), or by executing PMake as
+.CW make .'' ``
+In either case, PMake performs things exactly like Make (while still
+supporting most of the nice new features PMake provides). This
+includes:
+.IP \(bu 2
+No parallel execution.
+.IP \(bu 2
+Targets are made in the exact order specified by the makefile. The
+sources for each target are made in strict left-to-right order, etc.
+.IP \(bu 2
+A single Bourne shell is used to execute each command, thus the
+shell's
+.CW $$
+variable is useless, changing directories doesn't work across command
+lines, etc.
+.IP \(bu 2
+If no special characters exist in a command line, PMake will break the
+command into words itself and execute the command directly, without
+executing a shell first. The characters that cause PMake to execute a
+shell are:
+.CW # ,
+.CW = ,
+.CW | ,
+.CW ^ ,
+.CW ( ,
+.CW ) ,
+.CW { ,
+.CW } ,
+.CW ; ,
+.CW & ,
+.CW < ,
+.CW > ,
+.CW * ,
+.CW ? ,
+.CW [ ,
+.CW ] ,
+.CW : ,
+.CW $ ,
+.CW ` ,
+and
+.CW \e .
+You should notice that these are all the characters that are given
+special meaning by the shell (except
+.CW '
+and
+.CW " ,
+which PMake deals with all by its lonesome).
+.IP \(bu 2
+The use of the null suffix is turned off.
+.Ix 0 ref "null suffix"
+.Ix 0 ref suffix null
+.xH 2 The Way Things Work
+.LP
+When PMake reads the makefile, it parses sources and targets into
+nodes in a graph. The graph is directed only in the sense that PMake
+knows which way is up. Each node contains not only links to all its
+parents and children (the nodes that depend on it and those on which
+it depends, respectively), but also a count of the number of its
+children that have already been processed.
+.LP
+The most important thing to know about how PMake uses this graph is
+that the traversal is breadth-first and occurs in two passes.
+.LP
+After PMake has parsed the makefile, it begins with the nodes the user
+has told it to make (either on the command line, or via a
+.CW .MAIN
+target, or by the target being the first in the file not labeled with
+the
+.CW .NOTMAIN
+attribute) placed in a queue. It continues to take the node off the
+front of the queue, mark it as something that needs to be made, pass
+the node to
+.CW Suff_FindDeps
+(mentioned earlier) to find any implicit sources for the node, and
+place all the node's children that have yet to be marked at the end of
+the queue. If any of the children is a
+.CW .USE
+rule, its attributes are applied to the parent, then its commands are
+appended to the parent's list of commands and its children are linked
+to its parent. The parent's unmade children counter is then decremented
+(since the
+.CW .USE
+node has been processed). You will note that this allows a
+.CW .USE
+node to have children that are
+.CW .USE
+nodes and the rules will be applied in sequence.
+If the node has no children, it is placed at the end of
+another queue to be examined in the second pass. This process
+continues until the first queue is empty.
+.LP
+At this point, all the leaves of the graph are in the examination
+queue. PMake removes the node at the head of the queue and sees if it
+is out-of-date. If it is, it is passed to a function that will execute
+the commands for the node asynchronously. When the commands have
+completed, all the node's parents have their unmade children counter
+decremented and, if the counter is then 0, they are placed on the
+examination queue. Likewise, if the node is up-to-date. Only those
+parents that were marked on the downward pass are processed in this
+way. Thus PMake traverses the graph back up to the nodes the user
+instructed it to create. When the examination queue is empty and no
+shells are running to create a target, PMake is finished.
+.LP
+Once all targets have been processed, PMake executes the commands
+attached to the
+.CW .END
+target, either explicitly or through the use of an ellipsis in a shell
+script. If there were no errors during the entire process but there
+are still some targets unmade (PMake keeps a running count of how many
+targets are left to be made), there is a cycle in the graph. PMake does
+a depth-first traversal of the graph to find all the targets that
+weren't made and prints them out one by one.
+.xH 1 Answers to Exercises
+.IP (3.1)
+This is something of a trick question, for which I apologize. The
+trick comes from the UNIX definition of a suffix, which PMake doesn't
+necessarily share. You will have noticed that all the suffixes used in
+this tutorial (and in UNIX in general) begin with a period
+.CW .ms , (
+.CW .c ,
+etc.). Now, PMake's idea of a suffix is more like English's: it's the
+characters at the end of a word. With this in mind, one possible
+.Ix 0 def suffix
+solution to this problem goes as follows:
+.DS I
+\&.SUFFIXES : ec.exe .exe ec.obj .obj .asm
+ec.objec.exe .obj.exe :
+ link -o $(.TARGET) $(.IMPSRC)
+\&.asmec.obj :
+ asm -o $(.TARGET) -DDO_ERROR_CHECKING $(.IMPSRC)
+\&.asm.obj :
+ asm -o $(.TARGET) $(.IMPSRC)
+.DE
+.IP (3.2)
+The trick to this one lies in the ``:='' variable-assignment operator
+and the ``:S'' variable-expansion modifier.
+.Ix 0 ref variable assignment expanded
+.Ix 0 ref variable expansion modified
+.Ix 0 ref modifier substitute
+.Ix 0 ref :S
+.Ix 0 ref :=
+Basically what you want is to take the pointer variable, so to speak,
+and transform it into an invocation of the variable at which it
+points. You might try something like
+.DS I
+$(PTR:S/^/\e$(/:S/$/))
+.DE
+which places
+.CW $( '' ``
+at the front of the variable name and
+.CW ) '' ``
+at the end, thus transforming
+.CW VAR ,'' ``
+for example, into
+.CW $(VAR) ,'' ``
+which is just what we want. Unfortunately (as you know if you've tried
+it), since, as it says in the hint, PMake does no further substitution
+on the result of a modified expansion, that's \fIall\fP you get. The
+solution is to make use of ``:='' to place that string into yet
+another variable, then invoke the other variable directly:
+.DS I
+*PTR := $(PTR:S/^/\e$(/:S/$/)/)
+.DE
+You can then use
+.CW $(*PTR) '' ``
+to your heart's content.

+.xH 1 Glossary of Jargon
+.Gp "attribute"
+A property given to a target that causes PMake to treat it differently.
+.Gp "command script"
+The lines immediately following a dependency line that specify
+commands to execute to create each of the targets on the dependency
+line. Each line in the command script must begin with a tab.
+.Gp "command-line variable"
+A variable defined in an argument when PMake is first executed.
+Overrides all assignments to the same variable name in the makefile.
+.Gp "conditional"
+A construct much like that used in C that allows a makefile to be
+configured on the fly based on the local environment, or on what is being
+made by that invocation of PMake.
+.Gp "creation script"
+Commands used to create a target. See ``command script.''
+.Gp "dependency"
+The relationship between a source and a target. This comes in three
+flavors, as indicated by the operator between the target and the
+source. `:' gives a straight time-wise dependency (if the target is
+older than the source, the target is out-of-date), while `!' provides
+simply an ordering and always considers the target out-of-date. `::'
+is much like `:', save it creates multiple instances of a target each
+of which depends on its own list of sources.
+.Gp "dynamic source"
+This refers to a source that has a local variable invocation in it. It
+allows a single dependency line to specify a different source for each
+target on the line.
+.Gp "global variable"
+Any variable defined in a makefile. Takes precedence over variables
+defined in the environment, but not over command-line or local variables.
+.Gp "input graph"
+What PMake constructs from a makefile. Consists of nodes made of the
+targets in the makefile, and the links between them (the
+dependencies). The links are directed (from source to target) and
+there may not be any cycles (loops) in the graph.
+.Gp "local variable"
+A variable defined by PMake visible only in a target's shell script.
+There are seven local variables, not all of which are defined for
+every target:
+.CW .TARGET ,
+.CW .ALLSRC ,
+.CW .OODATE ,
+.CW .PREFIX ,
+.CW .IMPSRC ,
+.CW .ARCHIVE ,
+and
+.CW .MEMBER .
+.CW .TARGET ,
+.CW .PREFIX ,
+.CW .ARCHIVE ,
+and
+.CW .MEMBER
+may be used on dependency lines to create ``dynamic sources.''
+.Gp "makefile"
+A file that describes how a system is built. If you don't know what it
+is after reading this tutorial.\|.\|.\|.
+.Gp "modifier"
+A letter, following a colon, used to alter how a variable is expanded.
+It has no effect on the variable itself.
+.Gp "operator"
+What separates a source from a target (on a dependency line) and specifies
+the relationship between the two. There are three:
+.CW : ', `
+.CW :: ', `
+and
+.CW ! '. `
+.Gp "search path"
+A list of directories in which a file should be sought. PMake's view
+of the contents of directories in a search path does not change once
+the makefile has been read. A file is sought on a search path only if
+it is exclusively a source.
+.Gp "shell"
+A program to which commands are passed in order to create targets.
+.Gp "source"
+Anything to the right of an operator on a dependency line. Targets on
+the dependency line are usually created from the sources.
+.Gp "special target"
+A target that causes PMake to do special things when it's encountered.
+.Gp "suffix"
+The tail end of a file name. Usually begins with a period,
+.CW .c
+or
+.CW .ms ,
+e.g.
+.Gp "target"
+A word to the left of the operator on a dependency line. More
+generally, any file that PMake might create. A file may be (and often
+is) both a target and a source (what it is depends on how PMake is
+looking at it at the time \*- sort of like the wave/particle duality
+of light, you know).
+.Gp "transformation rule"
+A special construct in a makefile that specifies how to create a file
+of one type from a file of another, as indicated by their suffixes.
+.Gp "variable expansion"
+The process of substituting the value of a variable for a reference to
+it. Expansion may be altered by means of modifiers.
+.Gp "variable"
+A place in which to store text that may be retrieved later. Also used
+to define the local environment. Conditionals exist that test whether
+a variable is defined or not.

+ bmake
+ *****
+
+This directory contains a port of the BSD make tool (from NetBSD).
+Since 1993 I have run it on AIX, BSDi, Darwin, FreeBSD, HP-UX, IRIX,
+Linux, Minix, OSF, Solaris, SunOS and even UTS.
+Others have run it on many more systems.
+
+Currently each release is tested on NetBSD, FreeBSD, Solaris and Linux.
+
+Since 2003 bmake switched to a date based version (first was 20030714)
+which generally represents the date it was last merged with NetBSD's
+make. Since then, NetBSD's make is imported within a week of any
+interesting changes, so that bmake tracks it very closely.
+
+Building
+========
+
+The preferred way to bootstrap bmake is::
+
+ ./bmake/boot-strap
+
+there are a number of args - most of which get passed to configure,
+eg.
+::
+
+ ./bmake/boot-strap --prefix=/opt
+
+see the boot-strap script for details.
+
+For folk that hate to read anything, since 20121212 you can also use
+the GNU standard process of::
+
+ ./configure; make; make install
+
+To make much use of bmake you will need the bsd.*.mk macros or my
+portable *.mk macros which are included with bmake since 20121212
+and separately available from
+http://www.crufty.net/ftp/pub/sjg/mk.tar.gz
+which will be links to the latest versions.
+
+Porting
+=======
+
+If you encounter a system that bmake does not build or work on *out of
+the box*, I welcome patches.
+If you can provide access to a suitable machine - even better.

- * arch.c --
- * Functions to manipulate libraries, archives and their members.
- *
- * Once again, cacheing/hashing comes into play in the manipulation
- * of archives. The first time an archive is referenced, all of its members'
- * headers are read and hashed and the archive closed again. All hashed
- * archives are kept on a list which is searched each time an archive member
- * is referenced.
- *
- * The interface to this module is:
- * Arch_ParseArchive Given an archive specification, return a list
- * of GNode's, one for each member in the spec.
- * FAILURE is returned if the specification is
- * invalid for some reason.
- *
- * Arch_Touch Alter the modification time of the archive
- * member described by the given node to be
- * the current time.
- *
- * Arch_TouchLib Update the modification time of the library
- * described by the given node. This is special
- * because it also updates the modification time
- * of the library's table of contents.
- *
- * Arch_MTime Find the modification time of a member of
- * an archive *in the archive*. The time is also
- * placed in the member's GNode. Returns the
- * modification time.
- *
- * Arch_MemTime Find the modification time of a member of
- * an archive. Called when the member doesn't
- * already exist. Looks in the archive for the
- * modification time. Returns the modification
- * time.
- *
- * Arch_FindLib Search for a library along a path. The
- * library name in the GNode should be in
- * -l<name> format.
- *
- * Arch_LibOODate Special function to decide if a library node
- * is out-of-date.
- *
- * Arch_Init Initialize this module.
- *
- * Arch_End Cleanup this module.

+ *
+ * Arch_TouchLib Update the modification time of the library
+ * described by the given node. This is special
+ * because it also updates the modification time
+ * of the library's table of contents.
+ *
+ * Arch_MTime Find the modification time of a member of
+ * an archive *in the archive*. The time is also
+ * placed in the member's GNode. Returns the
+ * modification time.
+ *
+ * Arch_MemTime Find the modification time of a member of
+ * an archive. Called when the member doesn't
+ * already exist. Looks in the archive for the
+ * modification time. Returns the modification
+ * time.
+ *
+ * Arch_FindLib Search for a library along a path. The

-.Nd maintain program dependencies
-.Sh SYNOPSIS
-.Nm
-.Op Fl BeikNnqrstWwX
-.Op Fl C Ar directory
-.Op Fl D Ar variable
-.Op Fl d Ar flags
-.Op Fl f Ar makefile
-.Op Fl I Ar directory
-.Op Fl J Ar private
-.Op Fl j Ar max_jobs
-.Op Fl m Ar directory
-.Op Fl T Ar file
-.Op Fl V Ar variable
-.Op Ar variable=value
-.Op Ar target ...
-.Sh DESCRIPTION
-.Nm
-is a program designed to simplify the maintenance of other programs.
-Its input is a list of specifications as to the files upon which programs
-and other files depend.
-If no
-.Fl f Ar makefile
-makefile option is given,
-.Nm
-will try to open
-.Ql Pa makefile
-then
-.Ql Pa Makefile
-in order to find the specifications.
-If the file
-.Ql Pa .depend
-exists, it is read (see
-.Xr mkdep 1 ) .
-.Pp
-This manual page is intended as a reference document only.
-For a more thorough description of
-.Nm
-and makefiles, please refer to
-.%T "PMake \- A Tutorial" .
-.Pp
-.Nm
-will prepend the contents of the
-.Va MAKEFLAGS
-environment variable to the command line arguments before parsing them.
-.Pp
-The options are as follows:
-.Bl -tag -width Ds
-.It Fl B
-Try to be backwards compatible by executing a single shell per command and
-by executing the commands to make the sources of a dependency line in sequence.
-.It Fl C Ar directory
-Change to
-.Ar directory
-before reading the makefiles or doing anything else.
-If multiple
-.Fl C
-options are specified, each is interpreted relative to the previous one:
-.Fl C Pa / Fl C Pa etc
-is equivalent to
-.Fl C Pa /etc .
-.It Fl D Ar variable
-Define
-.Ar variable
-to be 1, in the global context.
-.It Fl d Ar [-]flags
-Turn on debugging, and specify which portions of
-.Nm
-are to print debugging information.
-Unless the flags are preceded by
-.Ql \-
-they are added to the
-.Va MAKEFLAGS
-environment variable and will be processed by any child make processes.
-By default, debugging information is printed to standard error,
-but this can be changed using the
-.Ar F
-debugging flag.
-The debugging output is always unbuffered; in addition, if debugging
-is enabled but debugging output is not directed to standard output,
-then the standard output is line buffered.
-.Ar Flags
-is one or more of the following:
-.Bl -tag -width Ds
-.It Ar A
-Print all possible debugging information;
-equivalent to specifying all of the debugging flags.
-.It Ar a
-Print debugging information about archive searching and caching.
-.It Ar C
-Print debugging information about current working directory.
-.It Ar c
-Print debugging information about conditional evaluation.
-.It Ar d
-Print debugging information about directory searching and caching.
-.It Ar e
-Print debugging information about failed commands and targets.
-.It Ar F Ns Oo Sy \&+ Oc Ns Ar filename
-Specify where debugging output is written.
-This must be the last flag, because it consumes the remainder of
-the argument.
-If the character immediately after the
-.Ql F
-flag is
-.Ql \&+ ,
-then the file will be opened in append mode;
-otherwise the file will be overwritten.
-If the file name is
-.Ql stdout
-or
-.Ql stderr
-then debugging output will be written to the
-standard output or standard error output file descriptors respectively
-(and the
-.Ql \&+
-option has no effect).
-Otherwise, the output will be written to the named file.
-If the file name ends
-.Ql .%d
-then the
-.Ql %d
-is replaced by the pid.
-.It Ar f
-Print debugging information about loop evaluation.
-.It Ar "g1"
-Print the input graph before making anything.
-.It Ar "g2"
-Print the input graph after making everything, or before exiting
-on error.
-.It Ar "g3"
-Print the input graph before exiting on error.
-.It Ar j
-Print debugging information about running multiple shells.
-.It Ar l
-Print commands in Makefiles regardless of whether or not they are prefixed by
-.Ql @
-or other "quiet" flags.
-Also known as "loud" behavior.
-.It Ar M
-Print debugging information about "meta" mode decisions about targets.
-.It Ar m
-Print debugging information about making targets, including modification
-dates.
-.It Ar n
-Don't delete the temporary command scripts created when running commands.
-These temporary scripts are created in the directory
-referred to by the
-.Ev TMPDIR
-environment variable, or in
-.Pa /tmp
-if
-.Ev TMPDIR
-is unset or set to the empty string.
-The temporary scripts are created by
-.Xr mkstemp 3 ,
-and have names of the form
-.Pa makeXXXXXX .
-.Em NOTE :
-This can create many files in
-.Ev TMPDIR
-or
-.Pa /tmp ,
-so use with care.
-.It Ar p
-Print debugging information about makefile parsing.
-.It Ar s
-Print debugging information about suffix-transformation rules.
-.It Ar t
-Print debugging information about target list maintenance.
-.It Ar V
-Force the
-.Fl V
-option to print raw values of variables.
-.It Ar v
-Print debugging information about variable assignment.
-.It Ar w
-Print entering and leaving directory messages, pre and post processing.
-.It Ar x
-Run shell commands with
-.Fl x
-so the actual commands are printed as they are executed.
-.El
-.It Fl e
-Specify that environment variables override macro assignments within
-makefiles.
-.It Fl f Ar makefile
-Specify a makefile to read instead of the default
-.Ql Pa makefile .
-If
-.Ar makefile
-is
-.Ql Fl ,
-standard input is read.
-Multiple makefiles may be specified, and are read in the order specified.
-.It Fl I Ar directory
-Specify a directory in which to search for makefiles and included makefiles.
-The system makefile directory (or directories, see the
-.Fl m
-option) is automatically included as part of this list.
-.It Fl i
-Ignore non-zero exit of shell commands in the makefile.
-Equivalent to specifying
-.Ql Fl
-before each command line in the makefile.
-.It Fl J Ar private
-This option should
-.Em not
-be specified by the user.
-.Pp
-When the
-.Ar j
-option is in use in a recursive build, this option is passed by a make
-to child makes to allow all the make processes in the build to
-cooperate to avoid overloading the system.
-.It Fl j Ar max_jobs
-Specify the maximum number of jobs that
-.Nm
-may have running at any one time.
-The value is saved in
-.Va .MAKE.JOBS .
-Turns compatibility mode off, unless the
-.Ar B
-flag is also specified.
-When compatibility mode is off, all commands associated with a
-target are executed in a single shell invocation as opposed to the
-traditional one shell invocation per line.
-This can break traditional scripts which change directories on each
-command invocation and then expect to start with a fresh environment
-on the next line.
-It is more efficient to correct the scripts rather than turn backwards
-compatibility on.
-.It Fl k
-Continue processing after errors are encountered, but only on those targets
-that do not depend on the target whose creation caused the error.
-.It Fl m Ar directory
-Specify a directory in which to search for sys.mk and makefiles included
-via the
-.Ao Ar file Ac Ns -style
-include statement.
-The
-.Fl m
-option can be used multiple times to form a search path.
-This path will override the default system include path: /usr/share/mk.
-Furthermore the system include path will be appended to the search path used
-for
-.Qo Ar file Qc Ns -style
-include statements (see the
-.Fl I
-option).
-.Pp
-If a file or directory name in the
-.Fl m
-argument (or the
-.Ev MAKESYSPATH
-environment variable) starts with the string
-.Qq \&.../
-then
-.Nm
-will search for the specified file or directory named in the remaining part
-of the argument string.
-The search starts with the current directory of
-the Makefile and then works upward towards the root of the filesystem.
-If the search is successful, then the resulting directory replaces the
-.Qq \&.../
-specification in the
-.Fl m
-argument.
-If used, this feature allows
-.Nm
-to easily search in the current source tree for customized sys.mk files
-(e.g., by using
-.Qq \&.../mk/sys.mk
-as an argument).
-.It Fl n
-Display the commands that would have been executed, but do not
-actually execute them unless the target depends on the .MAKE special
-source (see below).
-.It Fl N
-Display the commands which would have been executed, but do not
-actually execute any of them; useful for debugging top-level makefiles
-without descending into subdirectories.
-.It Fl q
-Do not execute any commands, but exit 0 if the specified targets are
-up-to-date and 1, otherwise.
-.It Fl r
-Do not use the built-in rules specified in the system makefile.
-.It Fl s
-Do not echo any commands as they are executed.
-Equivalent to specifying
-.Ql Ic @
-before each command line in the makefile.
-.It Fl T Ar tracefile
-When used with the
-.Fl j
-flag,
-append a trace record to
-.Ar tracefile
-for each job started and completed.
-.It Fl t
-Rather than re-building a target as specified in the makefile, create it
-or update its modification time to make it appear up-to-date.
-.It Fl V Ar variable
-Print
-.Nm Ns 's
-idea of the value of
-.Ar variable ,
-in the global context.
-Do not build any targets.
-Multiple instances of this option may be specified;
-the variables will be printed one per line,
-with a blank line for each null or undefined variable.
-If
-.Ar variable
-contains a
-.Ql \&$
-then the value will be expanded before printing.
-.It Fl W
-Treat any warnings during makefile parsing as errors.
-.It Fl X
-Don't export variables passed on the command line to the environment
-individually.
-Variables passed on the command line are still exported
-via the
-.Va MAKEFLAGS
-environment variable.
-This option may be useful on systems which have a small limit on the
-size of command arguments.
-.It Ar variable=value
-Set the value of the variable
-.Ar variable
-to
-.Ar value .
-Normally, all values passed on the command line are also exported to
-sub-makes in the environment.
-The
-.Fl X
-flag disables this behavior.
-Variable assignments should follow options for POSIX compatibility
-but no ordering is enforced.
-.El
-.Pp
-There are seven different types of lines in a makefile: file dependency
-specifications, shell commands, variable assignments, include statements,
-conditional directives, for loops, and comments.
-.Pp
-In general, lines may be continued from one line to the next by ending
-them with a backslash
-.Pq Ql \e .
-The trailing newline character and initial whitespace on the following
-line are compressed into a single space.
-.Sh FILE DEPENDENCY SPECIFICATIONS
-Dependency lines consist of one or more targets, an operator, and zero
-or more sources.
-This creates a relationship where the targets
-.Dq depend
-on the sources
-and are usually created from them.
-The exact relationship between the target and the source is determined
-by the operator that separates them.
-The three operators are as follows:
-.Bl -tag -width flag
-.It Ic \&:
-A target is considered out-of-date if its modification time is less than
-those of any of its sources.
-Sources for a target accumulate over dependency lines when this operator
-is used.
-The target is removed if
-.Nm
-is interrupted.
-.It Ic \&!
-Targets are always re-created, but not until all sources have been
-examined and re-created as necessary.
-Sources for a target accumulate over dependency lines when this operator
-is used.
-The target is removed if
-.Nm
-is interrupted.
-.It Ic \&::
-If no sources are specified, the target is always re-created.
-Otherwise, a target is considered out-of-date if any of its sources has
-been modified more recently than the target.
-Sources for a target do not accumulate over dependency lines when this
-operator is used.
-The target will not be removed if
-.Nm
-is interrupted.
-.El
-.Pp
-Targets and sources may contain the shell wildcard values
-.Ql \&? ,
-.Ql * ,
-.Ql [] ,
-and
-.Ql {} .
-The values
-.Ql \&? ,
-.Ql * ,
-and
-.Ql []
-may only be used as part of the final
-component of the target or source, and must be used to describe existing
-files.
-The value
-.Ql {}
-need not necessarily be used to describe existing files.
-Expansion is in directory order, not alphabetically as done in the shell.
-.Sh SHELL COMMANDS
-Each target may have associated with it a series of shell commands, normally
-used to create the target.
-Each of the commands in this script
-.Em must
-be preceded by a tab.
-While any target may appear on a dependency line, only one of these
-dependencies may be followed by a creation script, unless the
-.Ql Ic \&::
-operator is used.
-.Pp
-If the first characters of the command line are any combination of
-.Ql Ic @ ,
-.Ql Ic + ,
-or
-.Ql Ic \- ,
-the command is treated specially.
-A
-.Ql Ic @
-causes the command not to be echoed before it is executed.
-A
-.Ql Ic +
-causes the command to be executed even when
-.Fl n
-is given.
-This is similar to the effect of the .MAKE special source,
-except that the effect can be limited to a single line of a script.
-A
-.Ql Ic \-
-causes any non-zero exit status of the command line to be ignored.
-.Pp
-When
-.Nm
-is run in jobs mode with
-.Fl j Ar max_jobs ,
-the entire script for the target is fed to a
-single instance of the shell.
-.Pp
-In compatibility (non-jobs) mode, each command is run in a separate process.
-If the command contains any shell meta characters
-.Pq Ql #=|^(){};&<>*?[]:$`\e\en
-it will be passed to the shell, otherwise
-.Nm
-will attempt direct execution.
-.Pp
-Since
-.Nm
-will
-.Xr chdir 2
-to
-.Ql Va .OBJDIR
-before executing any targets, each child process
-starts with that as its current working directory.
-.Pp
-Makefiles should be written so that the mode of
-.Nm
-operation does not change their behavior.
-For example, any command which needs to use
-.Dq cd
-or
-.Dq chdir ,
-without side-effect should be put in parenthesis:
-.Bd -literal -offset indent
-
-avoid-chdir-side-effects:
- @echo Building $@ in `pwd`
- @(cd ${.CURDIR} && ${.MAKE} $@)
- @echo Back in `pwd`
-
-ensure-one-shell-regardless-of-mode:
- @echo Building $@ in `pwd`; \\
- (cd ${.CURDIR} && ${.MAKE} $@); \\
- echo Back in `pwd`
-.Ed
-.Sh VARIABLE ASSIGNMENTS
-Variables in make are much like variables in the shell, and, by tradition,
-consist of all upper-case letters.
-.Ss Variable assignment modifiers
-The five operators that can be used to assign values to variables are as
-follows:
-.Bl -tag -width Ds
-.It Ic \&=
-Assign the value to the variable.
-Any previous value is overridden.
-.It Ic \&+=
-Append the value to the current value of the variable.
-.It Ic \&?=
-Assign the value to the variable if it is not already defined.
-.It Ic \&:=
-Assign with expansion, i.e. expand the value before assigning it
-to the variable.
-Normally, expansion is not done until the variable is referenced.
-.Em NOTE :
-References to undefined variables are
-.Em not
-expanded.
-This can cause problems when variable modifiers are used.
-.It Ic \&!=
-Expand the value and pass it to the shell for execution and assign
-the result to the variable.
-Any newlines in the result are replaced with spaces.
-.El
-.Pp
-Any white-space before the assigned
-.Ar value
-is removed; if the value is being appended, a single space is inserted
-between the previous contents of the variable and the appended value.
-.Pp
-Variables are expanded by surrounding the variable name with either
-curly braces
-.Pq Ql {}
-or parentheses
-.Pq Ql ()
-and preceding it with
-a dollar sign
-.Pq Ql \&$ .
-If the variable name contains only a single letter, the surrounding
-braces or parentheses are not required.
-This shorter form is not recommended.
-.Pp
-If the variable name contains a dollar, then the name itself is expanded first.
-This allows almost arbitrary variable names, however names containing dollar,
-braces, parenthesis, or whitespace are really best avoided!
-.Pp
-If the result of expanding a variable contains a dollar sign
-.Pq Ql \&$
-the string is expanded again.
-.Pp
-Variable substitution occurs at three distinct times, depending on where
-the variable is being used.
-.Bl -enum
-.It
-Variables in dependency lines are expanded as the line is read.
-.It
-Variables in shell commands are expanded when the shell command is
-executed.
-.It
-.Dq .for
-loop index variables are expanded on each loop iteration.
-Note that other variables are not expanded inside loops so
-the following example code:
-.Bd -literal -offset indent
-
-.Dv .for i in 1 2 3
-a+= ${i}
-j= ${i}
-b+= ${j}
-.Dv .endfor
-
-all:
- @echo ${a}
- @echo ${b}
-
-.Ed
-will print:
-.Bd -literal -offset indent
-1 2 3
-3 3 3
-
-.Ed
-Because while ${a} contains
-.Dq 1 2 3
-after the loop is executed, ${b}
-contains
-.Dq ${j} ${j} ${j}
-which expands to
-.Dq 3 3 3
-since after the loop completes ${j} contains
-.Dq 3 .
-.El
-.Ss Variable classes
-The four different classes of variables (in order of increasing precedence)
-are:
-.Bl -tag -width Ds
-.It Environment variables
-Variables defined as part of
-.Nm Ns 's
-environment.
-.It Global variables
-Variables defined in the makefile or in included makefiles.
-.It Command line variables
-Variables defined as part of the command line.
-.It Local variables
-Variables that are defined specific to a certain target.
-The seven local variables are as follows:
-.Bl -tag -width ".ARCHIVE"
-.It Va .ALLSRC
-The list of all sources for this target; also known as
-.Ql Va \&\*[Gt] .
-.It Va .ARCHIVE
-The name of the archive file.
-.It Va .IMPSRC
-In suffix-transformation rules, the name/path of the source from which the
-target is to be transformed (the
-.Dq implied
-source); also known as
-.Ql Va \&\*[Lt] .
-It is not defined in explicit rules.
-.It Va .MEMBER
-The name of the archive member.
-.It Va .OODATE
-The list of sources for this target that were deemed out-of-date; also
-known as
-.Ql Va \&? .
-.It Va .PREFIX
-The file prefix of the target, containing only the file portion, no suffix
-or preceding directory components; also known as
-.Ql Va * .
-.It Va .TARGET
-The name of the target; also known as
-.Ql Va @ .
-.El
-.Pp
-The shorter forms
-.Ql Va @ ,
-.Ql Va \&? ,
-.Ql Va \&\*[Lt] ,
-.Ql Va \&\*[Gt] ,
-and
-.Ql Va *
-are permitted for backward
-compatibility with historical makefiles and are not recommended.
-The six variables
-.Ql Va "@F" ,
-.Ql Va "@D" ,
-.Ql Va "\*[Lt]F" ,
-.Ql Va "\*[Lt]D" ,
-.Ql Va "*F" ,
-and
-.Ql Va "*D"
-are permitted for compatibility with
-.At V
-makefiles and are not recommended.
-.Pp
-Four of the local variables may be used in sources on dependency lines
-because they expand to the proper value for each target on the line.
-These variables are
-.Ql Va .TARGET ,
-.Ql Va .PREFIX ,
-.Ql Va .ARCHIVE ,
-and
-.Ql Va .MEMBER .
-.El
-.Ss Additional built-in variables
-In addition,
-.Nm
-sets or knows about the following variables:
-.Bl -tag -width .MAKEOVERRIDES
-.It Va \&$
-A single dollar sign
-.Ql \&$ ,
-i.e.
-.Ql \&$$
-expands to a single dollar
-sign.
-.It Va .ALLTARGETS
-The list of all targets encountered in the Makefile.
-If evaluated during
-Makefile parsing, lists only those targets encountered thus far.
-.It Va .CURDIR
-A path to the directory where
-.Nm
-was executed.
-Refer to the description of
-.Ql Ev PWD
-for more details.
-.It Va .INCLUDEDFROMDIR
-The directory of the file this Makefile was included from.
-.It Va .INCLUDEDFROMFILE
-The filename of the file this Makefile was included from.
-.It Ev MAKE
-The name that
-.Nm
-was executed with
-.Pq Va argv[0] .
-For compatibility
-.Nm
-also sets
-.Va .MAKE
-with the same value.
-The preferred variable to use is the environment variable
-.Ev MAKE
-because it is more compatible with other versions of
-.Nm
-and cannot be confused with the special target with the same name.
-.It Va .MAKE.DEPENDFILE
-Names the makefile (default
-.Ql Pa .depend )
-from which generated dependencies are read.
-.It Va .MAKE.EXPAND_VARIABLES
-A boolean that controls the default behavior of the
-.Fl V
-option.
-.It Va .MAKE.EXPORTED
-The list of variables exported by
-.Nm .
-.It Va .MAKE.JOBS
-The argument to the
-.Fl j
-option.
-.It Va .MAKE.JOB.PREFIX
-If
-.Nm
-is run with
-.Ar j
-then output for each target is prefixed with a token
-.Ql --- target ---
-the first part of which can be controlled via
-.Va .MAKE.JOB.PREFIX .
-If
-.Va .MAKE.JOB.PREFIX
-is empty, no token is printed.
-.br
-For example:
-.Li .MAKE.JOB.PREFIX=${.newline}---${.MAKE:T}[${.MAKE.PID}]
-would produce tokens like
-.Ql ---make[1234] target ---
-making it easier to track the degree of parallelism being achieved.
-.It Ev MAKEFLAGS
-The environment variable
-.Ql Ev MAKEFLAGS
-may contain anything that
-may be specified on
-.Nm Ns 's
-command line.
-Anything specified on
-.Nm Ns 's
-command line is appended to the
-.Ql Ev MAKEFLAGS
-variable which is then
-entered into the environment for all programs which
-.Nm
-executes.
-.It Va .MAKE.LEVEL
-The recursion depth of
-.Nm .
-The initial instance of
-.Nm
-will be 0, and an incremented value is put into the environment
-to be seen by the next generation.
-This allows tests like:
-.Li .if ${.MAKE.LEVEL} == 0
-to protect things which should only be evaluated in the initial instance of
-.Nm .
-.It Va .MAKE.MAKEFILE_PREFERENCE
-The ordered list of makefile names
-(default
-.Ql Pa makefile ,
-.Ql Pa Makefile )
-that
-.Nm
-will look for.
-.It Va .MAKE.MAKEFILES
-The list of makefiles read by
-.Nm ,
-which is useful for tracking dependencies.
-Each makefile is recorded only once, regardless of the number of times read.
-.It Va .MAKE.MODE
-Processed after reading all makefiles.
-Can affect the mode that
-.Nm
-runs in.
-It can contain a number of keywords:
-.Bl -hang -width ignore-cmd
-.It Pa compat
-Like
-.Fl B ,
-puts
-.Nm
-into "compat" mode.
-.It Pa meta
-Puts
-.Nm
-into "meta" mode, where meta files are created for each target
-to capture the command run, the output generated and if
-.Xr filemon 4
-is available, the system calls which are of interest to
-.Nm .
-The captured output can be very useful when diagnosing errors.
-.It Pa curdirOk= Ar bf
-Normally
-.Nm
-will not create .meta files in
-.Ql Va .CURDIR .
-This can be overridden by setting
-.Va bf
-to a value which represents True.
-.It Pa env
-For debugging, it can be useful to inlcude the environment
-in the .meta file.
-.It Pa verbose
-If in "meta" mode, print a clue about the target being built.
-This is useful if the build is otherwise running silently.
-The message printed the value of:
-.Va .MAKE.META.PREFIX .
-.It Pa ignore-cmd
-Some makefiles have commands which are simply not stable.
-This keyword causes them to be ignored for
-determining whether a target is out of date in "meta" mode.
-See also
-.Ic .NOMETA_CMP .
-.It Pa silent= Ar bf
-If
-.Va bf
-is True, when a .meta file is created, mark the target
-.Ic .SILENT .
-.El
-.It Va .MAKE.META.BAILIWICK
-In "meta" mode, provides a list of prefixes which
-match the directories controlled by
-.Nm .
-If a file that was generated outside of
-.Va .OBJDIR
-but within said bailiwick is missing,
-the current target is considered out-of-date.
-.It Va .MAKE.META.CREATED
-In "meta" mode, this variable contains a list of all the meta files
-updated.
-If not empty, it can be used to trigger processing of
-.Va .MAKE.META.FILES .
-.It Va .MAKE.META.FILES
-In "meta" mode, this variable contains a list of all the meta files
-used (updated or not).
-This list can be used to process the meta files to extract dependency
-information.
-.It Va .MAKE.META.IGNORE_PATHS
-Provides a list of path prefixes that should be ignored;
-because the contents are expected to change over time.
-The default list includes:
-.Ql Pa /dev /etc /proc /tmp /var/run /var/tmp
-.It Va .MAKE.META.PREFIX
-Defines the message printed for each meta file updated in "meta verbose" mode.
-The default value is:
-.Dl Building ${.TARGET:H:tA}/${.TARGET:T}
-.It Va .MAKEOVERRIDES
-This variable is used to record the names of variables assigned to
-on the command line, so that they may be exported as part of
-.Ql Ev MAKEFLAGS .
-This behaviour can be disabled by assigning an empty value to
-.Ql Va .MAKEOVERRIDES
-within a makefile.
-Extra variables can be exported from a makefile
-by appending their names to
-.Ql Va .MAKEOVERRIDES .
-.Ql Ev MAKEFLAGS
-is re-exported whenever
-.Ql Va .MAKEOVERRIDES
-is modified.
-.It Va .MAKE.PATH_FILEMON
-If
-.Nm
-was built with
-.Xr filemon 4
-support, this is set to the path of the device node.
-This allows makefiles to test for this support.
-.It Va .MAKE.PID
-The process-id of
-.Nm .
-.It Va .MAKE.PPID
-The parent process-id of
-.Nm .
-.It Va MAKE_PRINT_VAR_ON_ERROR
-When
-.Nm
-stops due to an error, it prints its name and the value of
-.Ql Va .CURDIR
-as well as the value of any variables named in
-.Ql Va MAKE_PRINT_VAR_ON_ERROR .
-.It Va .newline
-This variable is simply assigned a newline character as its value.
-This allows expansions using the
-.Cm \&:@
-modifier to put a newline between
-iterations of the loop rather than a space.
-For example, the printing of
-.Ql Va MAKE_PRINT_VAR_ON_ERROR
-could be done as ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@}.
-.It Va .OBJDIR
-A path to the directory where the targets are built.
-Its value is determined by trying to
-.Xr chdir 2
-to the following directories in order and using the first match:
-.Bl -enum
-.It
-.Ev ${MAKEOBJDIRPREFIX}${.CURDIR}
-.Pp
-(Only if
-.Ql Ev MAKEOBJDIRPREFIX
-is set in the environment or on the command line.)
-.It
-.Ev ${MAKEOBJDIR}
-.Pp
-(Only if
-.Ql Ev MAKEOBJDIR
-is set in the environment or on the command line.)
-.It
-.Ev ${.CURDIR} Ns Pa /obj. Ns Ev ${MACHINE}
-.It
-.Ev ${.CURDIR} Ns Pa /obj
-.It
-.Pa /usr/obj/ Ns Ev ${.CURDIR}
-.It
-.Ev ${.CURDIR}
-.El
-.Pp
-Variable expansion is performed on the value before it's used,
-so expressions such as
-.Dl ${.CURDIR:S,^/usr/src,/var/obj,}
-may be used.
-This is especially useful with
-.Ql Ev MAKEOBJDIR .
-.Pp
-.Ql Va .OBJDIR
-may be modified in the makefile as a global variable.
-In all cases,
-.Nm
-will
-.Xr chdir 2
-to
-.Ql Va .OBJDIR
-and set
-.Ql Ev PWD
-to that directory before executing any targets.
-.
-.It Va .PARSEDIR
-A path to the directory of the current
-.Ql Pa Makefile
-being parsed.
-.It Va .PARSEFILE
-The basename of the current
-.Ql Pa Makefile
-being parsed.
-This variable and
-.Ql Va .PARSEDIR
-are both set only while the
-.Ql Pa Makefiles
-are being parsed.
-If you want to retain their current values, assign them to a variable
-using assignment with expansion:
-.Pq Ql Cm \&:= .
-.It Va .PATH
-A variable that represents the list of directories that
-.Nm
-will search for files.
-The search list should be updated using the target
-.Ql Va .PATH
-rather than the variable.
-.It Ev PWD
-Alternate path to the current directory.
-.Nm
-normally sets
-.Ql Va .CURDIR
-to the canonical path given by
-.Xr getcwd 3 .
-However, if the environment variable
-.Ql Ev PWD
-is set and gives a path to the current directory, then
-.Nm
-sets
-.Ql Va .CURDIR
-to the value of
-.Ql Ev PWD
-instead.
-This behaviour is disabled if
-.Ql Ev MAKEOBJDIRPREFIX
-is set or
-.Ql Ev MAKEOBJDIR
-contains a variable transform.
-.Ql Ev PWD
-is set to the value of
-.Ql Va .OBJDIR
-for all programs which
-.Nm
-executes.
-.It Ev .TARGETS
-The list of targets explicitly specified on the command line, if any.
-.It Ev VPATH
-Colon-separated
-.Pq Dq \&:
-lists of directories that
-.Nm
-will search for files.
-The variable is supported for compatibility with old make programs only,
-use
-.Ql Va .PATH
-instead.
-.El
-.Ss Variable modifiers
-Variable expansion may be modified to select or modify each word of the
-variable (where a
-.Dq word
-is white-space delimited sequence of characters).
-The general format of a variable expansion is as follows:
-.Pp
-.Dl ${variable[:modifier[:...]]}
-.Pp
-Each modifier begins with a colon,
-which may be escaped with a backslash
-.Pq Ql \e .
-.Pp
-A set of modifiers can be specified via a variable, as follows:
-.Pp
-.Dl modifier_variable=modifier[:...]
-.Dl ${variable:${modifier_variable}[:...]}
-.Pp
-In this case the first modifier in the modifier_variable does not
-start with a colon, since that must appear in the referencing
-variable.
-If any of the modifiers in the modifier_variable contain a dollar sign
-.Pq Ql $ ,
-these must be doubled to avoid early expansion.
-.Pp
-The supported modifiers are:
-.Bl -tag -width EEE
-.It Cm \&:E
-Replaces each word in the variable with its suffix.
-.It Cm \&:H
-Replaces each word in the variable with everything but the last component.
-.It Cm \&:M Ns Ar pattern
-Select only those words that match
-.Ar pattern .
-The standard shell wildcard characters
-.Pf ( Ql * ,
-.Ql \&? ,
-and
-.Ql Oo Oc )
-may
-be used.
-The wildcard characters may be escaped with a backslash
-.Pq Ql \e .
-As a consequence of the way values are split into words, matched,
-and then joined, a construct like
-.Dl ${VAR:M*}
-will normalise the inter-word spacing, removing all leading and
-trailing space, and converting multiple consecutive spaces
-to single spaces.
-.
-.It Cm \&:N Ns Ar pattern
-This is identical to
-.Ql Cm \&:M ,
-but selects all words which do not match
-.Ar pattern .
-.It Cm \&:O
-Order every word in variable alphabetically.
-To sort words in
-reverse order use the
-.Ql Cm \&:O:[-1..1]
-combination of modifiers.
-.It Cm \&:Ox
-Randomize words in variable.
-The results will be different each time you are referring to the
-modified variable; use the assignment with expansion
-.Pq Ql Cm \&:=
-to prevent such behaviour.
-For example,
-.Bd -literal -offset indent
-LIST= uno due tre quattro
-RANDOM_LIST= ${LIST:Ox}
-STATIC_RANDOM_LIST:= ${LIST:Ox}
-
-all:
- @echo "${RANDOM_LIST}"
- @echo "${RANDOM_LIST}"
- @echo "${STATIC_RANDOM_LIST}"
- @echo "${STATIC_RANDOM_LIST}"
-.Ed
-may produce output similar to:
-.Bd -literal -offset indent
-quattro due tre uno
-tre due quattro uno
-due uno quattro tre
-due uno quattro tre
-.Ed
-.It Cm \&:Q
-Quotes every shell meta-character in the variable, so that it can be passed
-safely through recursive invocations of
-.Nm .
-.It Cm \&:R
-Replaces each word in the variable with everything but its suffix.
-.It Cm \&:gmtime
-The value is a format string for
-.Xr strftime 3 ,
-using the current
-.Xr gmtime 3 .
-.It Cm \&:hash
-Compute a 32bit hash of the value and encode it as hex digits.
-.It Cm \&:localtime
-The value is a format string for
-.Xr strftime 3 ,
-using the current
-.Xr localtime 3 .
-.It Cm \&:tA
-Attempt to convert variable to an absolute path using
-.Xr realpath 3 ,
-if that fails, the value is unchanged.
-.It Cm \&:tl
-Converts variable to lower-case letters.
-.It Cm \&:ts Ns Ar c
-Words in the variable are normally separated by a space on expansion.
-This modifier sets the separator to the character
-.Ar c .
-If
-.Ar c
-is omitted, then no separator is used.
-The common escapes (including octal numeric codes), work as expected.
-.It Cm \&:tu
-Converts variable to upper-case letters.
-.It Cm \&:tW
-Causes the value to be treated as a single word
-(possibly containing embedded white space).
-See also
-.Ql Cm \&:[*] .
-.It Cm \&:tw
-Causes the value to be treated as a sequence of
-words delimited by white space.
-See also
-.Ql Cm \&:[@] .
-.Sm off
-.It Cm \&:S No \&/ Ar old_string No \&/ Ar new_string No \&/ Op Cm 1gW
-.Sm on
-Modify the first occurrence of
-.Ar old_string
-in the variable's value, replacing it with
-.Ar new_string .
-If a
-.Ql g
-is appended to the last slash of the pattern, all occurrences
-in each word are replaced.
-If a
-.Ql 1
-is appended to the last slash of the pattern, only the first word
-is affected.
-If a
-.Ql W
-is appended to the last slash of the pattern,
-then the value is treated as a single word
-(possibly containing embedded white space).
-If
-.Ar old_string
-begins with a caret
-.Pq Ql ^ ,
-.Ar old_string
-is anchored at the beginning of each word.
-If
-.Ar old_string
-ends with a dollar sign
-.Pq Ql \&$ ,
-it is anchored at the end of each word.
-Inside
-.Ar new_string ,
-an ampersand
-.Pq Ql \*[Am]
-is replaced by
-.Ar old_string
-(without any
-.Ql ^
-or
-.Ql \&$ ) .
-Any character may be used as a delimiter for the parts of the modifier
-string.
-The anchoring, ampersand and delimiter characters may be escaped with a
-backslash
-.Pq Ql \e .
-.Pp
-Variable expansion occurs in the normal fashion inside both
-.Ar old_string
-and
-.Ar new_string
-with the single exception that a backslash is used to prevent the expansion
-of a dollar sign
-.Pq Ql \&$ ,
-not a preceding dollar sign as is usual.
-.Sm off
-.It Cm \&:C No \&/ Ar pattern No \&/ Ar replacement No \&/ Op Cm 1gW
-.Sm on
-The
-.Cm \&:C
-modifier is just like the
-.Cm \&:S
-modifier except that the old and new strings, instead of being
-simple strings, are an extended regular expression (see
-.Xr regex 3 )
-string
-.Ar pattern
-and an
-.Xr ed 1 Ns \-style
-string
-.Ar replacement .
-Normally, the first occurrence of the pattern
-.Ar pattern
-in each word of the value is substituted with
-.Ar replacement .
-The
-.Ql 1
-modifier causes the substitution to apply to at most one word; the
-.Ql g
-modifier causes the substitution to apply to as many instances of the
-search pattern
-.Ar pattern
-as occur in the word or words it is found in; the
-.Ql W
-modifier causes the value to be treated as a single word
-(possibly containing embedded white space).
-Note that
-.Ql 1
-and
-.Ql g
-are orthogonal; the former specifies whether multiple words are
-potentially affected, the latter whether multiple substitutions can
-potentially occur within each affected word.
-.Pp
-As for the
-.Cm \&:S
-modifier, the
-.Ar pattern
-and
-.Ar replacement
-are subjected to variable expansion before being parsed as
-regular expressions.
-.It Cm \&:T
-Replaces each word in the variable with its last component.
-.It Cm \&:u
-Remove adjacent duplicate words (like
-.Xr uniq 1 ) .
-.Sm off
-.It Cm \&:\&? Ar true_string Cm \&: Ar false_string
-.Sm on
-If the variable name (not its value), when parsed as a .if conditional
-expression, evaluates to true, return as its value the
-.Ar true_string ,
-otherwise return the
-.Ar false_string .
-Since the variable name is used as the expression, \&:\&? must be the
-first modifier after the variable name itself - which will, of course,
-usually contain variable expansions.
-A common error is trying to use expressions like
-.Dl ${NUMBERS:M42:?match:no}
-which actually tests defined(NUMBERS),
-to determine is any words match "42" you need to use something like:
-.Dl ${"${NUMBERS:M42}" != \&"\&":?match:no} .
-.It Ar :old_string=new_string
-This is the
-.At V
-style variable substitution.
-It must be the last modifier specified.
-If
-.Ar old_string
-or
-.Ar new_string
-do not contain the pattern matching character
-.Ar %
-then it is assumed that they are
-anchored at the end of each word, so only suffixes or entire
-words may be replaced.
-Otherwise
-.Ar %
-is the substring of
-.Ar old_string
-to be replaced in
-.Ar new_string .
-.Pp
-Variable expansion occurs in the normal fashion inside both
-.Ar old_string
-and
-.Ar new_string
-with the single exception that a backslash is used to prevent the
-expansion of a dollar sign
-.Pq Ql \&$ ,
-not a preceding dollar sign as is usual.
-.Sm off
-.It Cm \&:@ Ar temp Cm @ Ar string Cm @
-.Sm on
-This is the loop expansion mechanism from the OSF Development
-Environment (ODE) make.
-Unlike
-.Cm \&.for
-loops expansion occurs at the time of
-reference.
-Assign
-.Ar temp
-to each word in the variable and evaluate
-.Ar string .
-The ODE convention is that
-.Ar temp
-should start and end with a period.
-For example.
-.Dl ${LINKS:@.LINK.@${LN} ${TARGET} ${.LINK.}@}
-.Pp
-However a single character variable is often more readable:
-.Dl ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@}
-.It Cm \&:U Ns Ar newval
-If the variable is undefined
-.Ar newval
-is the value.
-If the variable is defined, the existing value is returned.
-This is another ODE make feature.
-It is handy for setting per-target CFLAGS for instance:
-.Dl ${_${.TARGET:T}_CFLAGS:U${DEF_CFLAGS}}
-If a value is only required if the variable is undefined, use:
-.Dl ${VAR:D:Unewval}
-.It Cm \&:D Ns Ar newval
-If the variable is defined
-.Ar newval
-is the value.
-.It Cm \&:L
-The name of the variable is the value.
-.It Cm \&:P
-The path of the node which has the same name as the variable
-is the value.
-If no such node exists or its path is null, then the
-name of the variable is used.
-In order for this modifier to work, the name (node) must at least have
-appeared on the rhs of a dependency.
-.Sm off
-.It Cm \&:\&! Ar cmd Cm \&!
-.Sm on
-The output of running
-.Ar cmd
-is the value.
-.It Cm \&:sh
-If the variable is non-empty it is run as a command and the output
-becomes the new value.
-.It Cm \&::= Ns Ar str
-The variable is assigned the value
-.Ar str
-after substitution.
-This modifier and its variations are useful in
-obscure situations such as wanting to set a variable when shell commands
-are being parsed.
-These assignment modifiers always expand to
-nothing, so if appearing in a rule line by themselves should be
-preceded with something to keep
-.Nm
-happy.
-.Pp
-The
-.Ql Cm \&::
-helps avoid false matches with the
-.At V
-style
-.Cm \&:=
-modifier and since substitution always occurs the
-.Cm \&::=
-form is vaguely appropriate.
-.It Cm \&::?= Ns Ar str
-As for
-.Cm \&::=
-but only if the variable does not already have a value.
-.It Cm \&::+= Ns Ar str
-Append
-.Ar str
-to the variable.
-.It Cm \&::!= Ns Ar cmd
-Assign the output of
-.Ar cmd
-to the variable.
-.It Cm \&:\&[ Ns Ar range Ns Cm \&]
-Selects one or more words from the value,
-or performs other operations related to the way in which the
-value is divided into words.
-.Pp
-Ordinarily, a value is treated as a sequence of words
-delimited by white space.
-Some modifiers suppress this behaviour,
-causing a value to be treated as a single word
-(possibly containing embedded white space).
-An empty value, or a value that consists entirely of white-space,
-is treated as a single word.
-For the purposes of the
-.Ql Cm \&:[]
-modifier, the words are indexed both forwards using positive integers
-(where index 1 represents the first word),
-and backwards using negative integers
-(where index \-1 represents the last word).
-.Pp
-The
-.Ar range
-is subjected to variable expansion, and the expanded result is
-then interpreted as follows:
-.Bl -tag -width index
-.\" :[n]
-.It Ar index
-Selects a single word from the value.
-.\" :[start..end]
-.It Ar start Ns Cm \&.. Ns Ar end
-Selects all words from
-.Ar start
-to
-.Ar end ,
-inclusive.
-For example,
-.Ql Cm \&:[2..-1]
-selects all words from the second word to the last word.
-If
-.Ar start
-is greater than
-.Ar end ,
-then the words are output in reverse order.
-For example,
-.Ql Cm \&:[-1..1]
-selects all the words from last to first.
-.\" :[*]
-.It Cm \&*
-Causes subsequent modifiers to treat the value as a single word
-(possibly containing embedded white space).
-Analogous to the effect of
-\&"$*\&"
-in Bourne shell.
-.\" :[0]
-.It 0
-Means the same as
-.Ql Cm \&:[*] .
-.\" :[*]
-.It Cm \&@
-Causes subsequent modifiers to treat the value as a sequence of words
-delimited by white space.
-Analogous to the effect of
-\&"$@\&"
-in Bourne shell.
-.\" :[#]
-.It Cm \&#
-Returns the number of words in the value.

-.Sh INCLUDE STATEMENTS, CONDITIONALS AND FOR LOOPS
-Makefile inclusion, conditional structures and for loops reminiscent
-of the C programming language are provided in
-.Nm .
-All such structures are identified by a line beginning with a single
-dot
-.Pq Ql \&.
-character.
-Files are included with either
-.Cm \&.include Aq Ar file
-or
-.Cm \&.include Pf \*q Ar file Ns \*q .
-Variables between the angle brackets or double quotes are expanded
-to form the file name.
-If angle brackets are used, the included makefile is expected to be in
-the system makefile directory.
-If double quotes are used, the including makefile's directory and any
-directories specified using the
-.Fl I
-option are searched before the system
-makefile directory.
-For compatibility with other versions of
-.Nm
-.Ql include file ...
-is also accepted.
-If the include statement is written as
-.Cm .-include
-or as
-.Cm .sinclude
-then errors locating and/or opening include files are ignored.
-.Pp
-Conditional expressions are also preceded by a single dot as the first
-character of a line.
-The possible conditionals are as follows:
-.Bl -tag -width Ds
-.It Ic .error Ar message
-The message is printed along with the name of the makefile and line number,
-then
-.Nm
-will exit.
-.It Ic .export Ar variable ...
-Export the specified global variable.
-If no variable list is provided, all globals are exported
-except for internal variables (those that start with
-.Ql \&. ) .
-This is not affected by the
-.Fl X
-flag, so should be used with caution.
-For compatibility with other
-.Nm
-programs
-.Ql export variable=value
-is also accepted.
-.Pp
-Appending a variable name to
-.Va .MAKE.EXPORTED
-is equivalent to exporting a variable.
-.It Ic .export-env Ar variable ...
-The same as
-.Ql .export ,
-except that the variable is not appended to
-.Va .MAKE.EXPORTED .
-This allows exporting a value to the environment which is different from that
-used by
-.Nm
-internally.
-.It Ic .info Ar message
-The message is printed along with the name of the makefile and line number.
-.It Ic .undef Ar variable
-Un-define the specified global variable.
-Only global variables may be un-defined.
-.It Ic .unexport Ar variable ...
-The opposite of
-.Ql .export .
-The specified global
-.Va variable
-will be removed from
-.Va .MAKE.EXPORTED .
-If no variable list is provided, all globals are unexported,
-and
-.Va .MAKE.EXPORTED
-deleted.
-.It Ic .unexport-env
-Unexport all globals previously exported and
-clear the environment inherited from the parent.
-This operation will cause a memory leak of the original environment,
-so should be used sparingly.
-Testing for
-.Va .MAKE.LEVEL
-being 0, would make sense.
-Also note that any variables which originated in the parent environment
-should be explicitly preserved if desired.
-For example:
-.Bd -literal -offset indent
-.Li .if ${.MAKE.LEVEL} == 0
-PATH := ${PATH}
-.Li .unexport-env
-.Li .export PATH
-.Li .endif
-.Pp
-.Ed
-Would result in an environment containing only
-.Ql Ev PATH ,
-which is the minimal useful environment.
-Actually
-.Ql Ev .MAKE.LEVEL
-will also be pushed into the new environment.
-.It Ic .warning Ar message
-The message prefixed by
-.Ql Pa warning:
-is printed along with the name of the makefile and line number.
-.It Ic \&.if Oo \&! Oc Ns Ar expression Op Ar operator expression ...
-Test the value of an expression.
-.It Ic .ifdef Oo \&! Oc Ns Ar variable Op Ar operator variable ...
-Test the value of a variable.
-.It Ic .ifndef Oo \&! Oc Ns Ar variable Op Ar operator variable ...
-Test the value of a variable.
-.It Ic .ifmake Oo \&! Oc Ns Ar target Op Ar operator target ...
-Test the target being built.
-.It Ic .ifnmake Oo \&! Ns Oc Ar target Op Ar operator target ...
-Test the target being built.
-.It Ic .else
-Reverse the sense of the last conditional.
-.It Ic .elif Oo \&! Ns Oc Ar expression Op Ar operator expression ...
-A combination of
-.Ql Ic .else
-followed by
-.Ql Ic .if .
-.It Ic .elifdef Oo \&! Oc Ns Ar variable Op Ar operator variable ...
-A combination of
-.Ql Ic .else
-followed by
-.Ql Ic .ifdef .
-.It Ic .elifndef Oo \&! Oc Ns Ar variable Op Ar operator variable ...
-A combination of
-.Ql Ic .else
-followed by
-.Ql Ic .ifndef .
-.It Ic .elifmake Oo \&! Oc Ns Ar target Op Ar operator target ...
-A combination of
-.Ql Ic .else
-followed by
-.Ql Ic .ifmake .
-.It Ic .elifnmake Oo \&! Oc Ns Ar target Op Ar operator target ...
-A combination of
-.Ql Ic .else
-followed by
-.Ql Ic .ifnmake .
-.It Ic .endif
-End the body of the conditional.
-.El
-.Pp
-The
-.Ar operator
-may be any one of the following:
-.Bl -tag -width "Cm XX"
-.It Cm \&|\&|
-Logical OR.
-.It Cm \&\*[Am]\*[Am]
-Logical
-.Tn AND ;
-of higher precedence than
-.Dq \&|\&| .
-.El
-.Pp
-As in C,
-.Nm
-will only evaluate a conditional as far as is necessary to determine
-its value.
-Parentheses may be used to change the order of evaluation.
-The boolean operator
-.Ql Ic \&!
-may be used to logically negate an entire
-conditional.
-It is of higher precedence than
-.Ql Ic \&\*[Am]\*[Am] .
-.Pp
-The value of
-.Ar expression
-may be any of the following:
-.Bl -tag -width defined
-.It Ic defined
-Takes a variable name as an argument and evaluates to true if the variable
-has been defined.
-.It Ic make
-Takes a target name as an argument and evaluates to true if the target
-was specified as part of
-.Nm Ns 's
-command line or was declared the default target (either implicitly or
-explicitly, see
-.Va .MAIN )
-before the line containing the conditional.
-.It Ic empty
-Takes a variable, with possible modifiers, and evaluates to true if
-the expansion of the variable would result in an empty string.
-.It Ic exists
-Takes a file name as an argument and evaluates to true if the file exists.
-The file is searched for on the system search path (see
-.Va .PATH ) .
-.It Ic target
-Takes a target name as an argument and evaluates to true if the target
-has been defined.
-.It Ic commands
-Takes a target name as an argument and evaluates to true if the target
-has been defined and has commands associated with it.
-.El
-.Pp
-.Ar Expression
-may also be an arithmetic or string comparison.
-Variable expansion is
-performed on both sides of the comparison, after which the integral
-values are compared.
-A value is interpreted as hexadecimal if it is
-preceded by 0x, otherwise it is decimal; octal numbers are not supported.
-The standard C relational operators are all supported.
-If after
-variable expansion, either the left or right hand side of a
-.Ql Ic ==
-or
-.Ql Ic "!="
-operator is not an integral value, then
-string comparison is performed between the expanded
-variables.
-If no relational operator is given, it is assumed that the expanded
-variable is being compared against 0 or an empty string in the case
-of a string comparison.
-.Pp
-When
-.Nm
-is evaluating one of these conditional expressions, and it encounters
-a (white-space separated) word it doesn't recognize, either the
-.Dq make
-or
-.Dq defined
-expression is applied to it, depending on the form of the conditional.
-If the form is
-.Ql Ic .ifdef ,
-.Ql Ic .ifndef ,
-or
-.Ql Ic .if
-the
-.Dq defined
-expression is applied.
-Similarly, if the form is
-.Ql Ic .ifmake
-or
-.Ql Ic .ifnmake , the
-.Dq make
-expression is applied.
-.Pp
-If the conditional evaluates to true the parsing of the makefile continues
-as before.
-If it evaluates to false, the following lines are skipped.
-In both cases this continues until a
-.Ql Ic .else
-or
-.Ql Ic .endif
-is found.
-.Pp
-For loops are typically used to apply a set of rules to a list of files.
-The syntax of a for loop is:
-.Pp
-.Bl -tag -compact -width Ds
-.It Ic \&.for Ar variable Oo Ar variable ... Oc Ic in Ar expression
-.It Aq make-rules
-.It Ic \&.endfor
-.El
-.Pp
-After the for
-.Ic expression
-is evaluated, it is split into words.
-On each iteration of the loop, one word is taken and assigned to each
-.Ic variable ,
-in order, and these
-.Ic variables
-are substituted into the
-.Ic make-rules
-inside the body of the for loop.
-The number of words must come out even; that is, if there are three
-iteration variables, the number of words provided must be a multiple
-of three.
-.Sh COMMENTS
-Comments begin with a hash
-.Pq Ql \&#
-character, anywhere but in a shell
-command line, and continue to the end of an unescaped new line.
-.Sh SPECIAL SOURCES (ATTRIBUTES)
-.Bl -tag -width .IGNOREx
-.It Ic .EXEC
-Target is never out of date, but always execute commands anyway.
-.It Ic .IGNORE
-Ignore any errors from the commands associated with this target, exactly
-as if they all were preceded by a dash
-.Pq Ql \- .
-.\" .It Ic .INVISIBLE
-.\" XXX
-.\" .It Ic .JOIN
-.\" XXX
-.It Ic .MADE
-Mark all sources of this target as being up-to-date.
-.It Ic .MAKE
-Execute the commands associated with this target even if the
-.Fl n
-or
-.Fl t
-options were specified.
-Normally used to mark recursive
-.Nm Ns s .
-.It Ic .META
-Create a meta file for the target, even if it is flagged as
-.Ic .PHONY ,
-.Ic .MAKE ,
-or
-.Ic .SPECIAL .
-Usage in conjunction with
-.Ic .MAKE
-is the most likely case.
-In "meta" mode, the target is out-of-date if the meta file is missing.
-.It Ic .NOMETA
-Do not create a meta file for the target.
-Meta files are also not created for
-.Ic .PHONY ,
-.Ic .MAKE ,
-or
-.Ic .SPECIAL
-targets.
-.It Ic .NOMETA_CMP
-Ignore differences in commands when deciding if target is out of date.
-This is useful if the command contains a value which always changes.
-If the number of commands change, though, the target will still be out of date.
-The same effect applies to any command line that uses the variable
-.Va .OODATE ,
-which can be used for that purpose even when not otherwise needed or desired:
-.Bd -literal -offset indent
-
-skip-compare-for-some:
- @echo this will be compared
- @echo this will not ${.OODATE:M.NOMETA_CMP}
- @echo this will also be compared
-
-.Ed
-The
-.Cm \&:M
-pattern suppresses any expansion of the unwanted variable.
-.It Ic .NOPATH
-Do not search for the target in the directories specified by
-.Ic .PATH .
-.It Ic .NOTMAIN
-Normally
-.Nm
-selects the first target it encounters as the default target to be built
-if no target was specified.
-This source prevents this target from being selected.
-.It Ic .OPTIONAL
-If a target is marked with this attribute and
-.Nm
-can't figure out how to create it, it will ignore this fact and assume
-the file isn't needed or already exists.
-.It Ic .PHONY
-The target does not
-correspond to an actual file; it is always considered to be out of date,
-and will not be created with the
-.Fl t
-option.
-Suffix-transformation rules are not applied to
-.Ic .PHONY
-targets.
-.It Ic .PRECIOUS
-When
-.Nm
-is interrupted, it normally removes any partially made targets.
-This source prevents the target from being removed.
-.It Ic .RECURSIVE
-Synonym for
-.Ic .MAKE .
-.It Ic .SILENT
-Do not echo any of the commands associated with this target, exactly
-as if they all were preceded by an at sign
-.Pq Ql @ .
-.It Ic .USE
-Turn the target into
-.Nm Ns 's
-version of a macro.
-When the target is used as a source for another target, the other target
-acquires the commands, sources, and attributes (except for
-.Ic .USE )
-of the
-source.
-If the target already has commands, the
-.Ic .USE
-target's commands are appended
-to them.
-.It Ic .USEBEFORE
-Exactly like
-.Ic .USE ,
-but prepend the
-.Ic .USEBEFORE
-target commands to the target.
-.It Ic .WAIT
-If
-.Ic .WAIT
-appears in a dependency line, the sources that precede it are
-made before the sources that succeed it in the line.
-Since the dependents of files are not made until the file itself
-could be made, this also stops the dependents being built unless they
-are needed for another branch of the dependency tree.
-So given:
-.Bd -literal
-x: a .WAIT b
- echo x
-a:
- echo a
-b: b1
- echo b
-b1:
- echo b1
-
-.Ed
-the output is always
-.Ql a ,
-.Ql b1 ,
-.Ql b ,
-.Ql x .
-.br
-The ordering imposed by
-.Ic .WAIT
-is only relevant for parallel makes.
-.El
-.Sh SPECIAL TARGETS
-Special targets may not be included with other targets, i.e. they must be
-the only target specified.
-.Bl -tag -width .BEGINx
-.It Ic .BEGIN
-Any command lines attached to this target are executed before anything
-else is done.
-.It Ic .DEFAULT
-This is sort of a
-.Ic .USE
-rule for any target (that was used only as a
-source) that
-.Nm
-can't figure out any other way to create.
-Only the shell script is used.
-The
-.Ic .IMPSRC
-variable of a target that inherits
-.Ic .DEFAULT Ns 's
-commands is set
-to the target's own name.
-.It Ic .END
-Any command lines attached to this target are executed after everything
-else is done.
-.It Ic .ERROR
-Any command lines attached to this target are executed when another target fails.
-The
-.Ic .ERROR_TARGET
-variable is set to the target that failed.
-See also
-.Ic MAKE_PRINT_VAR_ON_ERROR .
-.It Ic .IGNORE
-Mark each of the sources with the
-.Ic .IGNORE
-attribute.
-If no sources are specified, this is the equivalent of specifying the
-.Fl i
-option.
-.It Ic .INTERRUPT
-If
-.Nm
-is interrupted, the commands for this target will be executed.
-.It Ic .MAIN
-If no target is specified when
-.Nm
-is invoked, this target will be built.
-.It Ic .MAKEFLAGS
-This target provides a way to specify flags for
-.Nm
-when the makefile is used.
-The flags are as if typed to the shell, though the
-.Fl f
-option will have
-no effect.
-.\" XXX: NOT YET!!!!
-.\" .It Ic .NOTPARALLEL
-.\" The named targets are executed in non parallel mode.
-.\" If no targets are

-.It Ic .NOPATH
-Apply the

-attribute to any specified sources.
-.It Ic .NOTPARALLEL
-Disable parallel mode.
-.It Ic .NO_PARALLEL
-Synonym for
-.Ic .NOTPARALLEL ,
-for compatibility with other pmake variants.
-.It Ic .ORDER
-The named targets are made in sequence.
-This ordering does not add targets to the list of targets to be made.
-Since the dependents of a target do not get built until the target itself
-could be built, unless
-.Ql a
-is built by another part of the dependency graph,
-the following is a dependency loop:
-.Bd -literal
-\&.ORDER: b a
-b: a
-.Ed
-.Pp
-The ordering imposed by
-.Ic .ORDER
-is only relevant for parallel makes.
-.\" XXX: NOT YET!!!!
-.\" .It Ic .PARALLEL
-.\" The named targets are executed in parallel mode.
-.\" If no targets are
-.\" specified, then all targets are executed in parallel mode.
-.It Ic .PATH
-The sources are directories which are to be searched for files not
-found in the current directory.
-If no sources are specified, any previously specified directories are
-deleted.
-If the source is the special
-.Ic .DOTLAST
-target, then the current working
-directory is searched last.
-.It Ic .PATH. Ns Va suffix
-Like
-.Ic .PATH
-but applies only to files with a particular suffix.
-The suffix must have been previously declared with
-.Ic .SUFFIXES .
-.It Ic .PHONY
-Apply the
-.Ic .PHONY
-attribute to any specified sources.
-.It Ic .PRECIOUS
-Apply the
-.Ic .PRECIOUS
-attribute to any specified sources.
-If no sources are specified, the
-.Ic .PRECIOUS
-attribute is applied to every
-target in the file.
-.It Ic .SHELL
-Sets the shell that
-.Nm
-will use to execute commands.
-The sources are a set of
-.Ar field=value
-pairs.
-.Bl -tag -width hasErrCtls
-.It Ar name
-This is the minimal specification, used to select one of the builtin
-shell specs;
-.Ar sh ,
-.Ar ksh ,
-and
-.Ar csh .
-.It Ar path
-Specifies the path to the shell.
-.It Ar hasErrCtl
-Indicates whether the shell supports exit on error.
-.It Ar check
-The command to turn on error checking.
-.It Ar ignore
-The command to disable error checking.
-.It Ar echo
-The command to turn on echoing of commands executed.
-.It Ar quiet
-The command to turn off echoing of commands executed.
-.It Ar filter
-The output to filter after issuing the
-.Ar quiet
-command.
-It is typically identical to
-.Ar quiet .
-.It Ar errFlag
-The flag to pass the shell to enable error checking.
-.It Ar echoFlag
-The flag to pass the shell to enable command echoing.
-.It Ar newline
-The string literal to pass the shell that results in a single newline
-character when used outside of any quoting characters.
-.El
-Example:
-.Bd -literal
-\&.SHELL: name=ksh path=/bin/ksh hasErrCtl=true \e
- check="set \-e" ignore="set +e" \e
- echo="set \-v" quiet="set +v" filter="set +v" \e
- echoFlag=v errFlag=e newline="'\en'"
-.Ed
-.It Ic .SILENT
-Apply the
-.Ic .SILENT
-attribute to any specified sources.
-If no sources are specified, the
-.Ic .SILENT
-attribute is applied to every
-command in the file.
-.It Ic .STALE
-This target gets run when a dependency file contains stale entries, having
-.Va .ALLSRC
-set to the name of that dependency file.
-.It Ic .SUFFIXES
-Each source specifies a suffix to
-.Nm .
-If no sources are specified, any previously specified suffixes are deleted.
-It allows the creation of suffix-transformation rules.
-.Pp
-Example:
-.Bd -literal
-\&.SUFFIXES: .o
-\&.c.o:
- cc \-o ${.TARGET} \-c ${.IMPSRC}
-.Ed
-.El
-.Sh ENVIRONMENT
-.Nm
-uses the following environment variables, if they exist:
-.Ev MACHINE ,
-.Ev MACHINE_ARCH ,
-.Ev MAKE ,
-.Ev MAKEFLAGS ,
-.Ev MAKEOBJDIR ,
-.Ev MAKEOBJDIRPREFIX ,
-.Ev MAKESYSPATH ,
-.Ev PWD ,
-and
-.Ev TMPDIR .
-.Pp
-.Ev MAKEOBJDIRPREFIX
-and
-.Ev MAKEOBJDIR
-may only be set in the environment or on the command line to
-.Nm
-and not as makefile variables;
-see the description of
-.Ql Va .OBJDIR
-for more details.
-.Sh FILES
-.Bl -tag -width /usr/share/mk -compact
-.It .depend
-list of dependencies
-.It Makefile
-list of dependencies
-.It makefile
-list of dependencies
-.It sys.mk
-system makefile
-.It /usr/share/mk
-system makefile directory
-.El
-.Sh COMPATIBILITY
-The basic make syntax is compatible between different versions of make,
-however the special variables, variable modifiers and conditionals are not.
-.Pp
-The way that parallel makes are scheduled changed in
-NetBSD 4.0
-so that .ORDER and .WAIT apply recursively to the dependent nodes.
-The algorithms used may change again in the future.
-.Pp
-The way that .for loop variables are substituted changed after
-NetBSD 5.0
-so that they still appear to be variable expansions.
-In particular this stops them being treated as syntax, and removes some
-obscure problems using them in .if statements.
-.Sh SEE ALSO
-.Xr mkdep 1
-.Sh HISTORY
-.Nm
-is derived from NetBSD
-.Xr make 1 .
-It uses autoconf to facilitate portability to other platforms.
-.Pp
-A
-make
-command appeared in
-.At v7 .
-This
-make
-implementation is based on Adam De Boor's pmake program which was written
-for Sprite at Berkeley.
-It was designed to be a parallel distributed make running jobs on different
-machines using a daemon called
-.Dq customs .
-.Pp
-Historically the target/dependency
-.Dq FRC
-has been used to FoRCe rebuilding (since the target/dependency
-does not exist... unless someone creates an
-.Dq FRC
-file).
-.Sh BUGS
-The
-make
-syntax is difficult to parse without actually acting of the data.
-For instance finding the end of a variable use should involve scanning each
-the modifiers using the correct terminator for each field.
-In many places
-make
-just counts {} and () in order to find the end of a variable expansion.
-.Pp
-There is no way of escaping a space character in a filename.

+.It Fl B
+Try to be backwards compatible by executing a single shell per command and
+by executing the commands to make the sources of a dependency line in sequence.
+.It Fl C Ar directory
+Change to
+.Ar directory
+before reading the makefiles or doing anything else.
+If multiple
+.Fl C
+options are specified, each is interpreted relative to the previous one:
+.Fl C Pa / Fl C Pa etc
+is equivalent to
+.Fl C Pa /etc .
+.It Fl D Ar variable
+Define
+.Ar variable
+to be 1, in the global context.
+.It Fl d Ar [-]flags
+Turn on debugging, and specify which portions of
+.Nm
+are to print debugging information.
+Unless the flags are preceded by
+.Ql \-
+they are added to the
+.Va MAKEFLAGS
+environment variable and will be processed by any child make processes.
+By default, debugging information is printed to standard error,
+but this can be changed using the
+.Ar F
+debugging flag.
+The debugging output is always unbuffered; in addition, if debugging
+is enabled but debugging output is not directed to standard output,
+then the standard output is line buffered.
+.Ar Flags
+is one or more of the following:
+.Bl -tag -width Ds
+.It Ar A
+Print all possible debugging information;
+equivalent to specifying all of the debugging flags.
+.It Ar a
+Print debugging information about archive searching and caching.
+.It Ar C
+Print debugging information about current working directory.
+.It Ar c
+Print debugging information about conditional evaluation.
+.It Ar d
+Print debugging information about directory searching and caching.
+.It Ar e
+Print debugging information about failed commands and targets.
+.It Ar F Ns Oo Sy \&+ Oc Ns Ar filename
+Specify where debugging output is written.
+This must be the last flag, because it consumes the remainder of
+the argument.
+If the character immediately after the
+.Ql F
+flag is
+.Ql \&+ ,
+then the file will be opened in append mode;
+otherwise the file will be overwritten.
+If the file name is
+.Ql stdout
+or
+.Ql stderr
+then debugging output will be written to the
+standard output or standard error output file descriptors respectively
+(and the
+.Ql \&+
+option has no effect).
+Otherwise, the output will be written to the named file.
+If the file name ends
+.Ql .%d
+then the
+.Ql %d
+is replaced by the pid.
+.It Ar f
+Print debugging information about loop evaluation.
+.It Ar "g1"
+Print the input graph before making anything.
+.It Ar "g2"
+Print the input graph after making everything, or before exiting
+on error.
+.It Ar "g3"
+Print the input graph before exiting on error.
+.It Ar j
+Print debugging information about running multiple shells.
+.It Ar l
+Print commands in Makefiles regardless of whether or not they are prefixed by
+.Ql @
+or other "quiet" flags.
+Also known as "loud" behavior.
+.It Ar M
+Print debugging information about "meta" mode decisions about targets.
+.It Ar m
+Print debugging information about making targets, including modification
+dates.
+.It Ar n
+Don't delete the temporary command scripts created when running commands.
+These temporary scripts are created in the directory
+referred to by the
+.Ev TMPDIR
+environment variable, or in
+.Pa /tmp
+if
+.Ev TMPDIR
+is unset or set to the empty string.
+The temporary scripts are created by
+.Xr mkstemp 3 ,
+and have names of the form
+.Pa makeXXXXXX .
+.Em NOTE :
+This can create many files in
+.Ev TMPDIR
+or
+.Pa /tmp ,
+so use with care.
+.It Ar p
+Print debugging information about makefile parsing.
+.It Ar s
+Print debugging information about suffix-transformation rules.
+.It Ar t
+Print debugging information about target list maintenance.
+.It Ar V
+Force the
+.Fl V
+option to print raw values of variables, overriding the default behavior
+set via
+.Va .MAKE.EXPAND_VARIABLES .
+.It Ar v
+Print debugging information about variable assignment.
+.It Ar x
+Run shell commands with
+.Fl x
+so the actual commands are printed as they are executed.
+.El
+.It Fl e
+Specify that environment variables override macro assignments within
+makefiles.
+.It Fl f Ar makefile
+Specify a makefile to read instead of the default
+.Ql Pa makefile .
+If
+.Ar makefile
+is
+.Ql Fl ,
+standard input is read.
+Multiple makefiles may be specified, and are read in the order specified.
+.It Fl I Ar directory
+Specify a directory in which to search for makefiles and included makefiles.
+The system makefile directory (or directories, see the
+.Fl m
+option) is automatically included as part of this list.
+.It Fl i
+Ignore non-zero exit of shell commands in the makefile.
+Equivalent to specifying
+.Ql Fl
+before each command line in the makefile.
+.It Fl J Ar private
+This option should
+.Em not
+be specified by the user.
+.Pp
+When the
+.Ar j
+option is in use in a recursive build, this option is passed by a make
+to child makes to allow all the make processes in the build to
+cooperate to avoid overloading the system.
+.It Fl j Ar max_jobs
+Specify the maximum number of jobs that
+.Nm
+may have running at any one time.
+The value is saved in
+.Va .MAKE.JOBS .
+Turns compatibility mode off, unless the
+.Ar B
+flag is also specified.
+When compatibility mode is off, all commands associated with a
+target are executed in a single shell invocation as opposed to the
+traditional one shell invocation per line.
+This can break traditional scripts which change directories on each
+command invocation and then expect to start with a fresh environment
+on the next line.
+It is more efficient to correct the scripts rather than turn backwards
+compatibility on.
+.It Fl k
+Continue processing after errors are encountered, but only on those targets
+that do not depend on the target whose creation caused the error.
+.It Fl m Ar directory
+Specify a directory in which to search for sys.mk and makefiles included
+via the
+.Ao Ar file Ac Ns -style
+include statement.
+The
+.Fl m
+option can be used multiple times to form a search path.
+This path will override the default system include path: /usr/share/mk.
+Furthermore the system include path will be appended to the search path used
+for
+.Qo Ar file Qc Ns -style
+include statements (see the
+.Fl I
+option).
+.Pp
+If a file or directory name in the
+.Fl m
+argument (or the
+.Ev MAKESYSPATH
+environment variable) starts with the string
+.Qq \&.../
+then
+.Nm
+will search for the specified file or directory named in the remaining part
+of the argument string.
+The search starts with the current directory of
+the Makefile and then works upward towards the root of the file system.
+If the search is successful, then the resulting directory replaces the
+.Qq \&.../
+specification in the
+.Fl m
+argument.
+If used, this feature allows
+.Nm
+to easily search in the current source tree for customized sys.mk files
+(e.g., by using
+.Qq \&.../mk/sys.mk
+as an argument).
+.It Fl n
+Display the commands that would have been executed, but do not
+actually execute them unless the target depends on the .MAKE special
+source (see below).
+.It Fl N
+Display the commands which would have been executed, but do not
+actually execute any of them; useful for debugging top-level makefiles
+without descending into subdirectories.
+.It Fl q
+Do not execute any commands, but exit 0 if the specified targets are
+up-to-date and 1, otherwise.
+.It Fl r
+Do not use the built-in rules specified in the system makefile.
+.It Fl s
+Do not echo any commands as they are executed.
+Equivalent to specifying
+.Ql Ic @
+before each command line in the makefile.
+.It Fl T Ar tracefile
+When used with the
+.Fl j
+flag,
+append a trace record to
+.Ar tracefile
+for each job started and completed.
+.It Fl t
+Rather than re-building a target as specified in the makefile, create it
+or update its modification time to make it appear up-to-date.
+.It Fl V Ar variable
+Print the value of
+.Ar variable .
+Do not build any targets.
+Multiple instances of this option may be specified;
+the variables will be printed one per line,
+with a blank line for each null or undefined variable.
+The value printed is extracted from the global context after all
+makefiles have been read.
+By default, the raw variable contents (which may
+include additional unexpanded variable references) are shown.
+If
+.Ar variable
+contains a
+.Ql \&$
+then the value will be recursively expanded to its complete resultant
+text before printing.
+The expanded value will also be printed if
+.Va .MAKE.EXPAND_VARIABLES
+is set to true and
+the
+.Fl dV
+option has not been used to override it.
+Note that loop-local and target-local variables, as well as values
+taken temporarily by global variables during makefile processing, are
+not accessible via this option.
+The
+.Fl dv
+debug mode can be used to see these at the cost of generating
+substantial extraneous output.
+.It Fl v Ar variable
+Like
+.Fl V
+but the variable is always expanded to its complete value.
+.It Fl W
+Treat any warnings during makefile parsing as errors.
+.It Fl w
+Print entering and leaving directory messages, pre and post processing.
+.It Fl X
+Don't export variables passed on the command line to the environment
+individually.
+Variables passed on the command line are still exported
+via the
+.Va MAKEFLAGS
+environment variable.
+This option may be useful on systems which have a small limit on the
+size of command arguments.
+.It Ar variable=value
+Set the value of the variable
+.Ar variable
+to
+.Ar value .
+Normally, all values passed on the command line are also exported to
+sub-makes in the environment.
+The
+.Fl X
+flag disables this behavior.
+Variable assignments should follow options for POSIX compatibility
+but no ordering is enforced.
+.El
+.Pp
+There are seven different types of lines in a makefile: file dependency
+specifications, shell commands, variable assignments, include statements,
+conditional directives, for loops, and comments.
+.Pp
+In general, lines may be continued from one line to the next by ending
+them with a backslash
+.Pq Ql \e .
+The trailing newline character and initial whitespace on the following
+line are compressed into a single space.
+.Sh FILE DEPENDENCY SPECIFICATIONS
+Dependency lines consist of one or more targets, an operator, and zero
+or more sources.
+This creates a relationship where the targets
+.Dq depend
+on the sources
+and are usually created from them.
+The exact relationship between the target and the source is determined
+by the operator that separates them.
+The three operators are as follows:
+.Bl -tag -width flag
+.It Ic \&:
+A target is considered out-of-date if its modification time is less than
+those of any of its sources.
+Sources for a target accumulate over dependency lines when this operator
+is used.
+The target is removed if
+.Nm
+is interrupted.
+.It Ic \&!
+Targets are always re-created, but not until all sources have been
+examined and re-created as necessary.
+Sources for a target accumulate over dependency lines when this operator
+is used.
+The target is removed if
+.Nm
+is interrupted.
+.It Ic \&::
+If no sources are specified, the target is always re-created.
+Otherwise, a target is considered out-of-date if any of its sources has
+been modified more recently than the target.
+Sources for a target do not accumulate over dependency lines when this
+operator is used.
+The target will not be removed if
+.Nm
+is interrupted.
+.El
+.Pp
+Targets and sources may contain the shell wildcard values
+.Ql \&? ,
+.Ql * ,
+.Ql [] ,
+and
+.Ql {} .
+The values
+.Ql \&? ,
+.Ql * ,
+and
+.Ql []
+may only be used as part of the final
+component of the target or source, and must be used to describe existing
+files.
+The value
+.Ql {}
+need not necessarily be used to describe existing files.
+Expansion is in directory order, not alphabetically as done in the shell.
+.Sh SHELL COMMANDS
+Each target may have associated with it one or more lines of shell
+commands, normally
+used to create the target.
+Each of the lines in this script
+.Em must
+be preceded by a tab.
+(For historical reasons, spaces are not accepted.)
+While targets can appear in many dependency lines if desired, by
+default only one of these rules may be followed by a creation
+script.
+If the
+.Ql Ic \&::
+operator is used, however, all rules may include scripts and the
+scripts are executed in the order found.
+.Pp
+Each line is treated as a separate shell command, unless the end of
+line is escaped with a backslash
+.Pq Ql \e
+in which case that line and the next are combined.
+.\" The escaped newline is retained and passed to the shell, which
+.\" normally ignores it.
+.\" However, the tab at the beginning of the following line is removed.
+If the first characters of the command are any combination of
+.Ql Ic @ ,
+.Ql Ic + ,
+or
+.Ql Ic \- ,
+the command is treated specially.
+A
+.Ql Ic @
+causes the command not to be echoed before it is executed.
+A
+.Ql Ic +
+causes the command to be executed even when
+.Fl n
+is given.
+This is similar to the effect of the .MAKE special source,
+except that the effect can be limited to a single line of a script.
+A
+.Ql Ic \-
+in compatibility mode
+causes any non-zero exit status of the command line to be ignored.
+.Pp
+When
+.Nm
+is run in jobs mode with
+.Fl j Ar max_jobs ,
+the entire script for the target is fed to a
+single instance of the shell.
+In compatibility (non-jobs) mode, each command is run in a separate process.
+If the command contains any shell meta characters
+.Pq Ql #=|^(){};&<>*?[]:$`\e\en
+it will be passed to the shell; otherwise
+.Nm
+will attempt direct execution.
+If a line starts with
+.Ql Ic \-
+and the shell has ErrCtl enabled then failure of the command line
+will be ignored as in compatibility mode.
+Otherwise
+.Ql Ic \-
+affects the entire job;
+the script will stop at the first command line that fails,
+but the target will not be deemed to have failed.
+.Pp
+Makefiles should be written so that the mode of
+.Nm
+operation does not change their behavior.
+For example, any command which needs to use
+.Dq cd
+or
+.Dq chdir
+without potentially changing the directory for subsequent commands
+should be put in parentheses so it executes in a subshell.
+To force the use of one shell, escape the line breaks so as to make
+the whole script one command.
+For example:
+.Bd -literal -offset indent
+avoid-chdir-side-effects:
+ @echo Building $@ in `pwd`
+ @(cd ${.CURDIR} && ${MAKE} $@)
+ @echo Back in `pwd`
+
+ensure-one-shell-regardless-of-mode:
+ @echo Building $@ in `pwd`; \e
+ (cd ${.CURDIR} && ${MAKE} $@); \e
+ echo Back in `pwd`
+.Ed
+.Pp
+Since
+.Nm
+will
+.Xr chdir 2
+to
+.Ql Va .OBJDIR
+before executing any targets, each child process
+starts with that as its current working directory.
+.Sh VARIABLE ASSIGNMENTS
+Variables in make are much like variables in the shell, and, by tradition,
+consist of all upper-case letters.
+.Ss Variable assignment modifiers
+The five operators that can be used to assign values to variables are as
+follows:
+.Bl -tag -width Ds
+.It Ic \&=
+Assign the value to the variable.
+Any previous value is overridden.
+.It Ic \&+=
+Append the value to the current value of the variable.
+.It Ic \&?=
+Assign the value to the variable if it is not already defined.
+.It Ic \&:=
+Assign with expansion, i.e. expand the value before assigning it
+to the variable.
+Normally, expansion is not done until the variable is referenced.
+.Em NOTE :
+References to undefined variables are
+.Em not
+expanded.
+This can cause problems when variable modifiers are used.
+.It Ic \&!=
+Expand the value and pass it to the shell for execution and assign
+the result to the variable.
+Any newlines in the result are replaced with spaces.
+.El
+.Pp
+Any white-space before the assigned
+.Ar value
+is removed; if the value is being appended, a single space is inserted
+between the previous contents of the variable and the appended value.
+.Pp
+Variables are expanded by surrounding the variable name with either
+curly braces
+.Pq Ql {}
+or parentheses
+.Pq Ql ()
+and preceding it with
+a dollar sign
+.Pq Ql \&$ .
+If the variable name contains only a single letter, the surrounding
+braces or parentheses are not required.
+This shorter form is not recommended.
+.Pp
+If the variable name contains a dollar, then the name itself is expanded first.
+This allows almost arbitrary variable names, however names containing dollar,
+braces, parenthesis, or whitespace are really best avoided!
+.Pp
+If the result of expanding a variable contains a dollar sign
+.Pq Ql \&$
+the string is expanded again.
+.Pp
+Variable substitution occurs at three distinct times, depending on where
+the variable is being used.
+.Bl -enum
+.It
+Variables in dependency lines are expanded as the line is read.
+.It
+Variables in shell commands are expanded when the shell command is
+executed.
+.It
+.Dq .for
+loop index variables are expanded on each loop iteration.
+Note that other variables are not expanded inside loops so
+the following example code:
+.Bd -literal -offset indent
+
+.Dv .for i in 1 2 3
+a+= ${i}
+j= ${i}
+b+= ${j}
+.Dv .endfor
+
+all:
+ @echo ${a}
+ @echo ${b}
+
+.Ed
+will print:
+.Bd -literal -offset indent
+1 2 3
+3 3 3
+
+.Ed
+Because while ${a} contains
+.Dq 1 2 3
+after the loop is executed, ${b}
+contains
+.Dq ${j} ${j} ${j}
+which expands to
+.Dq 3 3 3
+since after the loop completes ${j} contains
+.Dq 3 .
+.El
+.Ss Variable classes
+The four different classes of variables (in order of increasing precedence)
+are:
+.Bl -tag -width Ds
+.It Environment variables
+Variables defined as part of
+.Nm Ns 's
+environment.
+.It Global variables
+Variables defined in the makefile or in included makefiles.
+.It Command line variables
+Variables defined as part of the command line.
+.It Local variables
+Variables that are defined specific to a certain target.
+.El
+.Pp
+Local variables are all built in and their values vary magically from
+target to target.
+It is not currently possible to define new local variables.
+The seven local variables are as follows:
+.Bl -tag -width ".ARCHIVE" -offset indent
+.It Va .ALLSRC
+The list of all sources for this target; also known as
+.Ql Va \&> .
+.It Va .ARCHIVE
+The name of the archive file; also known as
+.Ql Va \&! .
+.It Va .IMPSRC
+In suffix-transformation rules, the name/path of the source from which the
+target is to be transformed (the
+.Dq implied
+source); also known as
+.Ql Va \&< .
+It is not defined in explicit rules.
+.It Va .MEMBER
+The name of the archive member; also known as
+.Ql Va % .
+.It Va .OODATE
+The list of sources for this target that were deemed out-of-date; also
+known as
+.Ql Va \&? .
+.It Va .PREFIX
+The file prefix of the target, containing only the file portion, no suffix
+or preceding directory components; also known as
+.Ql Va * .
+The suffix must be one of the known suffixes declared with
+.Ic .SUFFIXES
+or it will not be recognized.
+.It Va .TARGET
+The name of the target; also known as
+.Ql Va @ .
+For compatibility with other makes this is an alias for
+.Ic .ARCHIVE
+in archive member rules.
+.El
+.Pp
+The shorter forms
+.Ql ( Va > ,
+.Ql Va \&! ,
+.Ql Va < ,
+.Ql Va % ,
+.Ql Va \&? ,
+.Ql Va * ,
+and
+.Ql Va @ )
+are permitted for backward
+compatibility with historical makefiles and legacy POSIX make and are
+not recommended.
+.Pp
+Variants of these variables with the punctuation followed immediately by
+.Ql D
+or
+.Ql F ,
+e.g.
+.Ql Va $(@D) ,
+are legacy forms equivalent to using the
+.Ql :H
+and
+.Ql :T
+modifiers.
+These forms are accepted for compatibility with
+.At V
+makefiles and POSIX but are not recommended.
+.Pp
+Four of the local variables may be used in sources on dependency lines
+because they expand to the proper value for each target on the line.
+These variables are
+.Ql Va .TARGET ,
+.Ql Va .PREFIX ,
+.Ql Va .ARCHIVE ,
+and
+.Ql Va .MEMBER .
+.Ss Additional built-in variables
+In addition,
+.Nm
+sets or knows about the following variables:
+.Bl -tag -width .MAKEOVERRIDES
+.It Va \&$
+A single dollar sign
+.Ql \&$ ,
+i.e.
+.Ql \&$$
+expands to a single dollar
+sign.
+.It Va .ALLTARGETS
+The list of all targets encountered in the Makefile.
+If evaluated during
+Makefile parsing, lists only those targets encountered thus far.
+.It Va .CURDIR
+A path to the directory where
+.Nm
+was executed.
+Refer to the description of
+.Ql Ev PWD
+for more details.
+.It Va .INCLUDEDFROMDIR
+The directory of the file this Makefile was included from.
+.It Va .INCLUDEDFROMFILE
+The filename of the file this Makefile was included from.
+.It Ev MAKE
+The name that
+.Nm
+was executed with
+.Pq Va argv[0] .
+For compatibility
+.Nm
+also sets
+.Va .MAKE
+with the same value.
+The preferred variable to use is the environment variable
+.Ev MAKE
+because it is more compatible with other versions of
+.Nm
+and cannot be confused with the special target with the same name.
+.It Va .MAKE.DEPENDFILE
+Names the makefile (default
+.Ql Pa .depend )
+from which generated dependencies are read.
+.It Va .MAKE.EXPAND_VARIABLES
+A boolean that controls the default behavior of the
+.Fl V
+option.
+If true, variable values printed with
+.Fl V
+are fully expanded; if false, the raw variable contents (which may
+include additional unexpanded variable references) are shown.
+.It Va .MAKE.EXPORTED
+The list of variables exported by
+.Nm .
+.It Va .MAKE.JOBS
+The argument to the
+.Fl j
+option.
+.It Va .MAKE.JOB.PREFIX
+If
+.Nm
+is run with
+.Ar j
+then output for each target is prefixed with a token
+.Ql --- target ---
+the first part of which can be controlled via
+.Va .MAKE.JOB.PREFIX .
+If
+.Va .MAKE.JOB.PREFIX
+is empty, no token is printed.
+.br
+For example:
+.Li .MAKE.JOB.PREFIX=${.newline}---${.MAKE:T}[${.MAKE.PID}]
+would produce tokens like
+.Ql ---make[1234] target ---
+making it easier to track the degree of parallelism being achieved.
+.It Ev MAKEFLAGS
+The environment variable
+.Ql Ev MAKEFLAGS
+may contain anything that
+may be specified on
+.Nm Ns 's
+command line.
+Anything specified on
+.Nm Ns 's
+command line is appended to the
+.Ql Ev MAKEFLAGS
+variable which is then
+entered into the environment for all programs which
+.Nm
+executes.
+.It Va .MAKE.LEVEL
+The recursion depth of
+.Nm .
+The initial instance of
+.Nm
+will be 0, and an incremented value is put into the environment
+to be seen by the next generation.
+This allows tests like:
+.Li .if ${.MAKE.LEVEL} == 0
+to protect things which should only be evaluated in the initial instance of
+.Nm .
+.It Va .MAKE.MAKEFILE_PREFERENCE
+The ordered list of makefile names
+(default
+.Ql Pa makefile ,
+.Ql Pa Makefile )
+that
+.Nm
+will look for.
+.It Va .MAKE.MAKEFILES
+The list of makefiles read by
+.Nm ,
+which is useful for tracking dependencies.
+Each makefile is recorded only once, regardless of the number of times read.
+.It Va .MAKE.MODE
+Processed after reading all makefiles.
+Can affect the mode that
+.Nm
+runs in.
+It can contain a number of keywords:
+.Bl -hang -width missing-filemon=bf.
+.It Pa compat
+Like
+.Fl B ,
+puts
+.Nm
+into "compat" mode.
+.It Pa meta
+Puts
+.Nm
+into "meta" mode, where meta files are created for each target
+to capture the command run, the output generated and if
+.Xr filemon 4
+is available, the system calls which are of interest to
+.Nm .
+The captured output can be very useful when diagnosing errors.
+.It Pa curdirOk= Ar bf
+Normally
+.Nm
+will not create .meta files in
+.Ql Va .CURDIR .
+This can be overridden by setting
+.Va bf
+to a value which represents True.
+.It Pa missing-meta= Ar bf
+If
+.Va bf
+is True, then a missing .meta file makes the target out-of-date.
+.It Pa missing-filemon= Ar bf
+If
+.Va bf
+is True, then missing filemon data makes the target out-of-date.
+.It Pa nofilemon
+Do not use
+.Xr filemon 4 .
+.It Pa env
+For debugging, it can be useful to include the environment
+in the .meta file.
+.It Pa verbose
+If in "meta" mode, print a clue about the target being built.
+This is useful if the build is otherwise running silently.
+The message printed the value of:
+.Va .MAKE.META.PREFIX .
+.It Pa ignore-cmd
+Some makefiles have commands which are simply not stable.
+This keyword causes them to be ignored for
+determining whether a target is out of date in "meta" mode.
+See also
+.Ic .NOMETA_CMP .
+.It Pa silent= Ar bf
+If
+.Va bf
+is True, when a .meta file is created, mark the target
+.Ic .SILENT .
+.El
+.It Va .MAKE.META.BAILIWICK
+In "meta" mode, provides a list of prefixes which
+match the directories controlled by
+.Nm .
+If a file that was generated outside of
+.Va .OBJDIR
+but within said bailiwick is missing,
+the current target is considered out-of-date.
+.It Va .MAKE.META.CREATED
+In "meta" mode, this variable contains a list of all the meta files
+updated.
+If not empty, it can be used to trigger processing of
+.Va .MAKE.META.FILES .
+.It Va .MAKE.META.FILES
+In "meta" mode, this variable contains a list of all the meta files
+used (updated or not).
+This list can be used to process the meta files to extract dependency
+information.
+.It Va .MAKE.META.IGNORE_PATHS
+Provides a list of path prefixes that should be ignored;
+because the contents are expected to change over time.
+The default list includes:
+.Ql Pa /dev /etc /proc /tmp /var/run /var/tmp
+.It Va .MAKE.META.IGNORE_PATTERNS
+Provides a list of patterns to match against pathnames.
+Ignore any that match.
+.It Va .MAKE.META.IGNORE_FILTER
+Provides a list of variable modifiers to apply to each pathname.
+Ignore if the expansion is an empty string.
+.It Va .MAKE.META.PREFIX
+Defines the message printed for each meta file updated in "meta verbose" mode.
+The default value is:
+.Dl Building ${.TARGET:H:tA}/${.TARGET:T}
+.It Va .MAKEOVERRIDES
+This variable is used to record the names of variables assigned to
+on the command line, so that they may be exported as part of
+.Ql Ev MAKEFLAGS .
+This behavior can be disabled by assigning an empty value to
+.Ql Va .MAKEOVERRIDES
+within a makefile.
+Extra variables can be exported from a makefile
+by appending their names to
+.Ql Va .MAKEOVERRIDES .
+.Ql Ev MAKEFLAGS
+is re-exported whenever
+.Ql Va .MAKEOVERRIDES
+is modified.
+.It Va .MAKE.PATH_FILEMON
+If
+.Nm

+becomes
+.Ql $
+per normal evaluation rules.
+.It Va MAKE_PRINT_VAR_ON_ERROR
+When
+.Nm
+stops due to an error, it sets
+.Ql Va .ERROR_TARGET
+to the name of the target that failed,
+.Ql Va .ERROR_CMD
+to the commands of the failed target,
+and in "meta" mode, it also sets
+.Ql Va .ERROR_CWD
+to the
+.Xr getcwd 3 ,
+and
+.Ql Va .ERROR_META_FILE
+to the path of the meta file (if any) describing the failed target.
+It then prints its name and the value of
+.Ql Va .CURDIR
+as well as the value of any variables named in
+.Ql Va MAKE_PRINT_VAR_ON_ERROR .
+.It Va .newline
+This variable is simply assigned a newline character as its value.
+This allows expansions using the
+.Cm \&:@
+modifier to put a newline between
+iterations of the loop rather than a space.
+For example, the printing of
+.Ql Va MAKE_PRINT_VAR_ON_ERROR
+could be done as ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@}.
+.It Va .OBJDIR
+A path to the directory where the targets are built.
+Its value is determined by trying to
+.Xr chdir 2
+to the following directories in order and using the first match:
+.Bl -enum
+.It
+.Ev ${MAKEOBJDIRPREFIX}${.CURDIR}
+.Pp
+(Only if
+.Ql Ev MAKEOBJDIRPREFIX
+is set in the environment or on the command line.)
+.It
+.Ev ${MAKEOBJDIR}

+.It
+.Ev ${.CURDIR} Ns Pa /obj
+.It
+.Pa /usr/obj/ Ns Ev ${.CURDIR}
+.It

+.El
+.Pp
+Variable expansion is performed on the value before it's used,
+so expressions such as
+.Dl ${.CURDIR:S,^/usr/src,/var/obj,}
+may be used.
+This is especially useful with
+.Ql Ev MAKEOBJDIR .
+.Pp
+.Ql Va .OBJDIR
+may be modified in the makefile via the special target
+.Ql Ic .OBJDIR .
+In all cases,
+.Nm
+will
+.Xr chdir 2
+to the specified directory if it exists, and set
+.Ql Va .OBJDIR
+and
+.Ql Ev PWD
+to that directory before executing any targets.
+.
+.It Va .PARSEDIR
+A path to the directory of the current
+.Ql Pa Makefile
+being parsed.
+.It Va .PARSEFILE
+The basename of the current
+.Ql Pa Makefile
+being parsed.
+This variable and
+.Ql Va .PARSEDIR
+are both set only while the
+.Ql Pa Makefiles
+are being parsed.
+If you want to retain their current values, assign them to a variable
+using assignment with expansion:
+.Pq Ql Cm \&:= .
+.It Va .PATH
+A variable that represents the list of directories that
+.Nm
+will search for files.
+The search list should be updated using the target
+.Ql Va .PATH
+rather than the variable.
+.It Ev PWD
+Alternate path to the current directory.
+.Nm
+normally sets
+.Ql Va .CURDIR
+to the canonical path given by
+.Xr getcwd 3 .
+However, if the environment variable
+.Ql Ev PWD
+is set and gives a path to the current directory, then
+.Nm
+sets
+.Ql Va .CURDIR
+to the value of
+.Ql Ev PWD
+instead.
+This behavior is disabled if
+.Ql Ev MAKEOBJDIRPREFIX
+is set or
+.Ql Ev MAKEOBJDIR
+contains a variable transform.
+.Ql Ev PWD
+is set to the value of
+.Ql Va .OBJDIR
+for all programs which
+.Nm
+executes.
+.It Ev .TARGETS
+The list of targets explicitly specified on the command line, if any.
+.It Ev VPATH
+Colon-separated
+.Pq Dq \&:
+lists of directories that
+.Nm
+will search for files.
+The variable is supported for compatibility with old make programs only,
+use
+.Ql Va .PATH
+instead.
+.El
+.Ss Variable modifiers
+Variable expansion may be modified to select or modify each word of the
+variable (where a
+.Dq word
+is white-space delimited sequence of characters).
+The general format of a variable expansion is as follows:
+.Pp
+.Dl ${variable[:modifier[:...]]}
+.Pp
+Each modifier begins with a colon,
+which may be escaped with a backslash
+.Pq Ql \e .
+.Pp
+A set of modifiers can be specified via a variable, as follows:
+.Pp
+.Dl modifier_variable=modifier[:...]
+.Dl ${variable:${modifier_variable}[:...]}
+.Pp
+In this case the first modifier in the modifier_variable does not
+start with a colon, since that must appear in the referencing
+variable.
+If any of the modifiers in the modifier_variable contain a dollar sign
+.Pq Ql $ ,
+these must be doubled to avoid early expansion.
+.Pp
+The supported modifiers are:
+.Bl -tag -width EEE
+.It Cm \&:E
+Replaces each word in the variable with its suffix.
+.It Cm \&:H
+Replaces each word in the variable with everything but the last component.
+.It Cm \&:M Ns Ar pattern
+Select only those words that match
+.Ar pattern .
+The standard shell wildcard characters
+.Pf ( Ql * ,
+.Ql \&? ,
+and
+.Ql Oo Oc )
+may
+be used.
+The wildcard characters may be escaped with a backslash
+.Pq Ql \e .
+As a consequence of the way values are split into words, matched,
+and then joined, a construct like
+.Dl ${VAR:M*}
+will normalize the inter-word spacing, removing all leading and
+trailing space, and converting multiple consecutive spaces
+to single spaces.
+.
+.It Cm \&:N Ns Ar pattern
+This is identical to
+.Ql Cm \&:M ,
+but selects all words which do not match
+.Ar pattern .
+.It Cm \&:O
+Order every word in variable alphabetically.
+To sort words in
+reverse order use the
+.Ql Cm \&:O:[-1..1]
+combination of modifiers.
+.It Cm \&:Ox
+Randomize words in variable.
+The results will be different each time you are referring to the
+modified variable; use the assignment with expansion
+.Pq Ql Cm \&:=
+to prevent such behavior.
+For example,
+.Bd -literal -offset indent
+LIST= uno due tre quattro
+RANDOM_LIST= ${LIST:Ox}
+STATIC_RANDOM_LIST:= ${LIST:Ox}
+
+all:
+ @echo "${RANDOM_LIST}"
+ @echo "${RANDOM_LIST}"
+ @echo "${STATIC_RANDOM_LIST}"
+ @echo "${STATIC_RANDOM_LIST}"
+.Ed
+may produce output similar to:
+.Bd -literal -offset indent
+quattro due tre uno
+tre due quattro uno
+due uno quattro tre
+due uno quattro tre
+.Ed
+.It Cm \&:Q
+Quotes every shell meta-character in the variable, so that it can be passed
+safely through recursive invocations of
+.Nm .
+.It Cm \&:R
+Replaces each word in the variable with everything but its suffix.
+.It Cm \&:range[=count]
+The value is an integer sequence representing the words of the original
+value, or the supplied
+.Va count .
+.It Cm \&:gmtime[=utc]
+The value is a format string for
+.Xr strftime 3 ,
+using
+.Xr gmtime 3 .
+If a
+.Va utc
+value is not provided or is 0, the current time is used.
+.It Cm \&:hash
+Compute a 32-bit hash of the value and encode it as hex digits.
+.It Cm \&:localtime[=utc]
+The value is a format string for
+.Xr strftime 3 ,
+using
+.Xr localtime 3 .
+If a
+.Va utc
+value is not provided or is 0, the current time is used.
+.It Cm \&:tA
+Attempt to convert variable to an absolute path using
+.Xr realpath 3 ,
+if that fails, the value is unchanged.
+.It Cm \&:tl
+Converts variable to lower-case letters.
+.It Cm \&:ts Ns Ar c
+Words in the variable are normally separated by a space on expansion.
+This modifier sets the separator to the character
+.Ar c .
+If
+.Ar c
+is omitted, then no separator is used.
+The common escapes (including octal numeric codes), work as expected.
+.It Cm \&:tu
+Converts variable to upper-case letters.
+.It Cm \&:tW
+Causes the value to be treated as a single word
+(possibly containing embedded white space).
+See also
+.Ql Cm \&:[*] .
+.It Cm \&:tw
+Causes the value to be treated as a sequence of
+words delimited by white space.
+See also
+.Ql Cm \&:[@] .
+.Sm off
+.It Cm \&:S No \&/ Ar old_string No \&/ Ar new_string No \&/ Op Cm 1gW
+.Sm on
+Modify the first occurrence of
+.Ar old_string
+in the variable's value, replacing it with
+.Ar new_string .
+If a
+.Ql g
+is appended to the last slash of the pattern, all occurrences
+in each word are replaced.
+If a
+.Ql 1
+is appended to the last slash of the pattern, only the first word
+is affected.
+If a
+.Ql W
+is appended to the last slash of the pattern,
+then the value is treated as a single word
+(possibly containing embedded white space).
+If
+.Ar old_string
+begins with a caret
+.Pq Ql ^ ,
+.Ar old_string
+is anchored at the beginning of each word.
+If
+.Ar old_string
+ends with a dollar sign
+.Pq Ql \&$ ,
+it is anchored at the end of each word.
+Inside
+.Ar new_string ,
+an ampersand
+.Pq Ql &
+is replaced by
+.Ar old_string
+(without any
+.Ql ^
+or
+.Ql \&$ ) .
+Any character may be used as a delimiter for the parts of the modifier
+string.
+The anchoring, ampersand and delimiter characters may be escaped with a
+backslash
+.Pq Ql \e .
+.Pp
+Variable expansion occurs in the normal fashion inside both
+.Ar old_string
+and
+.Ar new_string
+with the single exception that a backslash is used to prevent the expansion
+of a dollar sign
+.Pq Ql \&$ ,
+not a preceding dollar sign as is usual.
+.Sm off
+.It Cm \&:C No \&/ Ar pattern No \&/ Ar replacement No \&/ Op Cm 1gW
+.Sm on
+The
+.Cm \&:C
+modifier is just like the
+.Cm \&:S
+modifier except that the old and new strings, instead of being
+simple strings, are an extended regular expression (see
+.Xr regex 3 )
+string
+.Ar pattern
+and an
+.Xr ed 1 Ns \-style
+string
+.Ar replacement .
+Normally, the first occurrence of the pattern
+.Ar pattern
+in each word of the value is substituted with
+.Ar replacement .
+The
+.Ql 1
+modifier causes the substitution to apply to at most one word; the
+.Ql g
+modifier causes the substitution to apply to as many instances of the
+search pattern
+.Ar pattern
+as occur in the word or words it is found in; the
+.Ql W
+modifier causes the value to be treated as a single word
+(possibly containing embedded white space).
+Note that
+.Ql 1
+and
+.Ql g
+are orthogonal; the former specifies whether multiple words are
+potentially affected, the latter whether multiple substitutions can
+potentially occur within each affected word.
+.Pp
+As for the
+.Cm \&:S
+modifier, the
+.Ar pattern
+and
+.Ar replacement
+are subjected to variable expansion before being parsed as
+regular expressions.
+.It Cm \&:T
+Replaces each word in the variable with its last component.
+.It Cm \&:u
+Remove adjacent duplicate words (like
+.Xr uniq 1 ) .
+.Sm off
+.It Cm \&:\&? Ar true_string Cm \&: Ar false_string
+.Sm on
+If the variable name (not its value), when parsed as a .if conditional
+expression, evaluates to true, return as its value the
+.Ar true_string ,
+otherwise return the
+.Ar false_string .
+Since the variable name is used as the expression, \&:\&? must be the
+first modifier after the variable name itself - which will, of course,
+usually contain variable expansions.
+A common error is trying to use expressions like
+.Dl ${NUMBERS:M42:?match:no}
+which actually tests defined(NUMBERS),
+to determine is any words match "42" you need to use something like:
+.Dl ${"${NUMBERS:M42}" != \&"\&":?match:no} .
+.It Ar :old_string=new_string
+This is the
+.At V
+style variable substitution.
+It must be the last modifier specified.
+If
+.Ar old_string
+or
+.Ar new_string
+do not contain the pattern matching character
+.Ar %
+then it is assumed that they are
+anchored at the end of each word, so only suffixes or entire
+words may be replaced.
+Otherwise
+.Ar %
+is the substring of
+.Ar old_string
+to be replaced in
+.Ar new_string .
+.Pp
+Variable expansion occurs in the normal fashion inside both
+.Ar old_string
+and
+.Ar new_string
+with the single exception that a backslash is used to prevent the
+expansion of a dollar sign
+.Pq Ql \&$ ,
+not a preceding dollar sign as is usual.
+.Sm off
+.It Cm \&:@ Ar temp Cm @ Ar string Cm @
+.Sm on
+This is the loop expansion mechanism from the OSF Development
+Environment (ODE) make.
+Unlike
+.Cm \&.for
+loops expansion occurs at the time of
+reference.
+Assign
+.Ar temp
+to each word in the variable and evaluate
+.Ar string .
+The ODE convention is that
+.Ar temp
+should start and end with a period.
+For example.
+.Dl ${LINKS:@.LINK.@${LN} ${TARGET} ${.LINK.}@}
+.Pp
+However a single character variable is often more readable:
+.Dl ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@}
+.It Cm \&:_[=var]
+Save the current variable value in
+.Ql $_
+or the named
+.Va var
+for later reference.
+Example usage:
+.Bd -literal -offset indent
+M_cmpv.units = 1 1000 1000000
+M_cmpv = S,., ,g:_:range:@i at + $${_:[-$$i]} \&\\
+\\* $${M_cmpv.units:[$$i]}@:S,^,expr 0 ,1:sh
+
+.Dv .if ${VERSION:${M_cmpv}} < ${3.1.12:L:${M_cmpv}}
+
+.Ed
+Here
+.Ql $_
+is used to save the result of the
+.Ql :S
+modifier which is later referenced using the index values from
+.Ql :range .
+.It Cm \&:U Ns Ar newval
+If the variable is undefined
+.Ar newval
+is the value.
+If the variable is defined, the existing value is returned.
+This is another ODE make feature.
+It is handy for setting per-target CFLAGS for instance:
+.Dl ${_${.TARGET:T}_CFLAGS:U${DEF_CFLAGS}}
+If a value is only required if the variable is undefined, use:
+.Dl ${VAR:D:Unewval}
+.It Cm \&:D Ns Ar newval
+If the variable is defined
+.Ar newval
+is the value.
+.It Cm \&:L
+The name of the variable is the value.
+.It Cm \&:P
+The path of the node which has the same name as the variable
+is the value.
+If no such node exists or its path is null, then the
+name of the variable is used.
+In order for this modifier to work, the name (node) must at least have
+appeared on the rhs of a dependency.
+.Sm off
+.It Cm \&:\&! Ar cmd Cm \&!
+.Sm on
+The output of running
+.Ar cmd
+is the value.
+.It Cm \&:sh
+If the variable is non-empty it is run as a command and the output
+becomes the new value.
+.It Cm \&::= Ns Ar str
+The variable is assigned the value
+.Ar str
+after substitution.
+This modifier and its variations are useful in
+obscure situations such as wanting to set a variable when shell commands
+are being parsed.
+These assignment modifiers always expand to
+nothing, so if appearing in a rule line by themselves should be
+preceded with something to keep
+.Nm
+happy.
+.Pp
+The
+.Ql Cm \&::
+helps avoid false matches with the
+.At V
+style
+.Cm \&:=
+modifier and since substitution always occurs the
+.Cm \&::=
+form is vaguely appropriate.
+.It Cm \&::?= Ns Ar str
+As for
+.Cm \&::=
+but only if the variable does not already have a value.
+.It Cm \&::+= Ns Ar str
+Append
+.Ar str
+to the variable.
+.It Cm \&::!= Ns Ar cmd
+Assign the output of
+.Ar cmd
+to the variable.
+.It Cm \&:\&[ Ns Ar range Ns Cm \&]
+Selects one or more words from the value,
+or performs other operations related to the way in which the
+value is divided into words.
+.Pp
+Ordinarily, a value is treated as a sequence of words
+delimited by white space.
+Some modifiers suppress this behavior,
+causing a value to be treated as a single word
+(possibly containing embedded white space).
+An empty value, or a value that consists entirely of white-space,
+is treated as a single word.
+For the purposes of the
+.Ql Cm \&:[]
+modifier, the words are indexed both forwards using positive integers
+(where index 1 represents the first word),
+and backwards using negative integers
+(where index \-1 represents the last word).
+.Pp
+The
+.Ar range
+is subjected to variable expansion, and the expanded result is
+then interpreted as follows:
+.Bl -tag -width index
+.\" :[n]
+.It Ar index
+Selects a single word from the value.
+.\" :[start..end]
+.It Ar start Ns Cm \&.. Ns Ar end
+Selects all words from
+.Ar start
+to
+.Ar end ,
+inclusive.
+For example,
+.Ql Cm \&:[2..-1]
+selects all words from the second word to the last word.
+If
+.Ar start
+is greater than
+.Ar end ,
+then the words are output in reverse order.
+For example,
+.Ql Cm \&:[-1..1]
+selects all the words from last to first.
+.\" :[*]
+.It Cm \&*
+Causes subsequent modifiers to treat the value as a single word
+(possibly containing embedded white space).
+Analogous to the effect of
+\&"$*\&"
+in Bourne shell.
+.\" :[0]
+.It 0
+Means the same as
+.Ql Cm \&:[*] .
+.\" :[*]
+.It Cm \&@
+Causes subsequent modifiers to treat the value as a sequence of words
+delimited by white space.
+Analogous to the effect of
+\&"$@\&"

+.\" :[#]
+.It Cm \&#
+Returns the number of words in the value.

+.Sh INCLUDE STATEMENTS, CONDITIONALS AND FOR LOOPS
+Makefile inclusion, conditional structures and for loops reminiscent
+of the C programming language are provided in
+.Nm .
+All such structures are identified by a line beginning with a single
+dot
+.Pq Ql \&.
+character.
+Files are included with either
+.Cm \&.include Aq Ar file
+or
+.Cm \&.include Pf \*q Ar file Ns \*q .
+Variables between the angle brackets or double quotes are expanded
+to form the file name.
+If angle brackets are used, the included makefile is expected to be in
+the system makefile directory.
+If double quotes are used, the including makefile's directory and any
+directories specified using the
+.Fl I
+option are searched before the system
+makefile directory.
+For compatibility with other versions of
+.Nm
+.Ql include file ...
+is also accepted.
+.Pp
+If the include statement is written as
+.Cm .-include
+or as
+.Cm .sinclude
+then errors locating and/or opening include files are ignored.
+.Pp
+If the include statement is written as
+.Cm .dinclude
+not only are errors locating and/or opening include files ignored,
+but stale dependencies within the included file will be ignored
+just like
+.Va .MAKE.DEPENDFILE .
+.Pp
+Conditional expressions are also preceded by a single dot as the first
+character of a line.
+The possible conditionals are as follows:
+.Bl -tag -width Ds
+.It Ic .error Ar message
+The message is printed along with the name of the makefile and line number,
+then
+.Nm
+will exit.
+.It Ic .export Ar variable ...
+Export the specified global variable.
+If no variable list is provided, all globals are exported
+except for internal variables (those that start with
+.Ql \&. ) .
+This is not affected by the
+.Fl X
+flag, so should be used with caution.
+For compatibility with other
+.Nm
+programs
+.Ql export variable=value
+is also accepted.
+.Pp
+Appending a variable name to
+.Va .MAKE.EXPORTED
+is equivalent to exporting a variable.
+.It Ic .export-env Ar variable ...
+The same as
+.Ql .export ,
+except that the variable is not appended to
+.Va .MAKE.EXPORTED .
+This allows exporting a value to the environment which is different from that
+used by

+internally.
+.It Ic .export-literal Ar variable ...
+The same as
+.Ql .export-env ,
+except that variables in the value are not expanded.
+.It Ic .info Ar message
+The message is printed along with the name of the makefile and line number.
+.It Ic .undef Ar variable
+Un-define the specified global variable.
+Only global variables may be un-defined.
+.It Ic .unexport Ar variable ...
+The opposite of
+.Ql .export .
+The specified global
+.Va variable
+will be removed from
+.Va .MAKE.EXPORTED .
+If no variable list is provided, all globals are unexported,
+and
+.Va .MAKE.EXPORTED
+deleted.
+.It Ic .unexport-env
+Unexport all globals previously exported and
+clear the environment inherited from the parent.
+This operation will cause a memory leak of the original environment,
+so should be used sparingly.
+Testing for
+.Va .MAKE.LEVEL
+being 0, would make sense.
+Also note that any variables which originated in the parent environment
+should be explicitly preserved if desired.
+For example:
+.Bd -literal -offset indent
+.Li .if ${.MAKE.LEVEL} == 0
+PATH := ${PATH}
+.Li .unexport-env
+.Li .export PATH
+.Li .endif
+.Pp
+.Ed
+Would result in an environment containing only
+.Ql Ev PATH ,
+which is the minimal useful environment.
+Actually
+.Ql Ev .MAKE.LEVEL
+will also be pushed into the new environment.
+.It Ic .warning Ar message
+The message prefixed by
+.Ql Pa warning:
+is printed along with the name of the makefile and line number.

+.It Cm \&|\&|
+Logical OR.
+.It Cm \&&&
+Logical
+.Tn AND ;
+of higher precedence than
+.Dq \&|\&| .
+.El
+.Pp
+As in C,
+.Nm
+will only evaluate a conditional as far as is necessary to determine
+its value.
+Parentheses may be used to change the order of evaluation.
+The boolean operator
+.Ql Ic \&!
+may be used to logically negate an entire
+conditional.
+It is of higher precedence than
+.Ql Ic \&&& .
+.Pp
+The value of
+.Ar expression
+may be any of the following:
+.Bl -tag -width defined
+.It Ic defined
+Takes a variable name as an argument and evaluates to true if the variable
+has been defined.
+.It Ic make
+Takes a target name as an argument and evaluates to true if the target
+was specified as part of
+.Nm Ns 's
+command line or was declared the default target (either implicitly or
+explicitly, see
+.Va .MAIN )
+before the line containing the conditional.
+.It Ic empty
+Takes a variable, with possible modifiers, and evaluates to true if
+the expansion of the variable would result in an empty string.
+.It Ic exists
+Takes a file name as an argument and evaluates to true if the file exists.
+The file is searched for on the system search path (see
+.Va .PATH ) .
+.It Ic target
+Takes a target name as an argument and evaluates to true if the target
+has been defined.
+.It Ic commands
+Takes a target name as an argument and evaluates to true if the target
+has been defined and has commands associated with it.
+.El
+.Pp
+.Ar Expression
+may also be an arithmetic or string comparison.
+Variable expansion is
+performed on both sides of the comparison, after which the integral
+values are compared.
+A value is interpreted as hexadecimal if it is
+preceded by 0x, otherwise it is decimal; octal numbers are not supported.
+The standard C relational operators are all supported.
+If after
+variable expansion, either the left or right hand side of a
+.Ql Ic ==
+or
+.Ql Ic "!="
+operator is not an integral value, then
+string comparison is performed between the expanded
+variables.
+If no relational operator is given, it is assumed that the expanded
+variable is being compared against 0 or an empty string in the case
+of a string comparison.
+.Pp
+When
+.Nm
+is evaluating one of these conditional expressions, and it encounters
+a (white-space separated) word it doesn't recognize, either the
+.Dq make
+or
+.Dq defined
+expression is applied to it, depending on the form of the conditional.
+If the form is
+.Ql Ic .ifdef ,
+.Ql Ic .ifndef ,
+or
+.Ql Ic .if
+the
+.Dq defined
+expression is applied.
+Similarly, if the form is
+.Ql Ic .ifmake
+or
+.Ql Ic .ifnmake , the
+.Dq make
+expression is applied.
+.Pp
+If the conditional evaluates to true the parsing of the makefile continues
+as before.
+If it evaluates to false, the following lines are skipped.
+In both cases this continues until a
+.Ql Ic .else
+or
+.Ql Ic .endif
+is found.
+.Pp
+For loops are typically used to apply a set of rules to a list of files.
+The syntax of a for loop is:
+.Pp
+.Bl -tag -compact -width Ds
+.It Ic \&.for Ar variable Oo Ar variable ... Oc Ic in Ar expression
+.It Aq make-rules
+.It Ic \&.endfor
+.El
+.Pp
+After the for
+.Ic expression
+is evaluated, it is split into words.
+On each iteration of the loop, one word is taken and assigned to each
+.Ic variable ,
+in order, and these
+.Ic variables
+are substituted into the
+.Ic make-rules
+inside the body of the for loop.
+The number of words must come out even; that is, if there are three
+iteration variables, the number of words provided must be a multiple
+of three.
+.Sh COMMENTS
+Comments begin with a hash
+.Pq Ql \&#
+character, anywhere but in a shell
+command line, and continue to the end of an unescaped new line.
+.Sh SPECIAL SOURCES (ATTRIBUTES)
+.Bl -tag -width .IGNOREx
+.It Ic .EXEC
+Target is never out of date, but always execute commands anyway.
+.It Ic .IGNORE
+Ignore any errors from the commands associated with this target, exactly
+as if they all were preceded by a dash
+.Pq Ql \- .
+.\" .It Ic .INVISIBLE
+.\" XXX
+.\" .It Ic .JOIN
+.\" XXX
+.It Ic .MADE
+Mark all sources of this target as being up-to-date.
+.It Ic .MAKE
+Execute the commands associated with this target even if the
+.Fl n
+or
+.Fl t
+options were specified.
+Normally used to mark recursive
+.Nm Ns s .
+.It Ic .META
+Create a meta file for the target, even if it is flagged as
+.Ic .PHONY ,
+.Ic .MAKE ,
+or
+.Ic .SPECIAL .
+Usage in conjunction with
+.Ic .MAKE
+is the most likely case.
+In "meta" mode, the target is out-of-date if the meta file is missing.
+.It Ic .NOMETA
+Do not create a meta file for the target.
+Meta files are also not created for
+.Ic .PHONY ,
+.Ic .MAKE ,
+or
+.Ic .SPECIAL
+targets.
+.It Ic .NOMETA_CMP
+Ignore differences in commands when deciding if target is out of date.
+This is useful if the command contains a value which always changes.
+If the number of commands change, though, the target will still be out of date.
+The same effect applies to any command line that uses the variable
+.Va .OODATE ,
+which can be used for that purpose even when not otherwise needed or desired:
+.Bd -literal -offset indent
+
+skip-compare-for-some:
+ @echo this will be compared
+ @echo this will not ${.OODATE:M.NOMETA_CMP}
+ @echo this will also be compared
+
+.Ed
+The
+.Cm \&:M
+pattern suppresses any expansion of the unwanted variable.
+.It Ic .NOPATH
+Do not search for the target in the directories specified by
+.Ic .PATH .
+.It Ic .NOTMAIN
+Normally
+.Nm
+selects the first target it encounters as the default target to be built
+if no target was specified.
+This source prevents this target from being selected.
+.It Ic .OPTIONAL
+If a target is marked with this attribute and
+.Nm
+can't figure out how to create it, it will ignore this fact and assume
+the file isn't needed or already exists.
+.It Ic .PHONY
+The target does not
+correspond to an actual file; it is always considered to be out of date,
+and will not be created with the
+.Fl t
+option.
+Suffix-transformation rules are not applied to
+.Ic .PHONY
+targets.
+.It Ic .PRECIOUS
+When
+.Nm
+is interrupted, it normally removes any partially made targets.
+This source prevents the target from being removed.
+.It Ic .RECURSIVE
+Synonym for
+.Ic .MAKE .
+.It Ic .SILENT
+Do not echo any of the commands associated with this target, exactly
+as if they all were preceded by an at sign
+.Pq Ql @ .
+.It Ic .USE
+Turn the target into
+.Nm Ns 's
+version of a macro.
+When the target is used as a source for another target, the other target
+acquires the commands, sources, and attributes (except for
+.Ic .USE )
+of the
+source.
+If the target already has commands, the
+.Ic .USE
+target's commands are appended
+to them.
+.It Ic .USEBEFORE
+Exactly like
+.Ic .USE ,
+but prepend the
+.Ic .USEBEFORE
+target commands to the target.
+.It Ic .WAIT
+If
+.Ic .WAIT
+appears in a dependency line, the sources that precede it are
+made before the sources that succeed it in the line.
+Since the dependents of files are not made until the file itself
+could be made, this also stops the dependents being built unless they
+are needed for another branch of the dependency tree.
+So given:
+.Bd -literal
+x: a .WAIT b
+ echo x
+a:
+ echo a
+b: b1
+ echo b
+b1:
+ echo b1
+
+.Ed
+the output is always
+.Ql a ,
+.Ql b1 ,
+.Ql b ,
+.Ql x .
+.br
+The ordering imposed by
+.Ic .WAIT
+is only relevant for parallel makes.
+.El
+.Sh SPECIAL TARGETS
+Special targets may not be included with other targets, i.e. they must be
+the only target specified.
+.Bl -tag -width .BEGINx
+.It Ic .BEGIN
+Any command lines attached to this target are executed before anything
+else is done.
+.It Ic .DEFAULT
+This is sort of a
+.Ic .USE
+rule for any target (that was used only as a
+source) that
+.Nm
+can't figure out any other way to create.
+Only the shell script is used.
+The
+.Ic .IMPSRC
+variable of a target that inherits
+.Ic .DEFAULT Ns 's
+commands is set
+to the target's own name.
+.It Ic .DELETE_ON_ERROR
+If this target is present in the makefile, it globally causes make to
+delete targets whose commands fail.
+(By default, only targets whose commands are interrupted during
+execution are deleted.
+This is the historical behavior.)
+This setting can be used to help prevent half-finished or malformed
+targets from being left around and corrupting future rebuilds.
+.It Ic .END
+Any command lines attached to this target are executed after everything
+else is done.
+.It Ic .ERROR
+Any command lines attached to this target are executed when another target fails.
+The
+.Ic .ERROR_TARGET
+variable is set to the target that failed.
+See also
+.Ic MAKE_PRINT_VAR_ON_ERROR .
+.It Ic .IGNORE
+Mark each of the sources with the
+.Ic .IGNORE
+attribute.
+If no sources are specified, this is the equivalent of specifying the
+.Fl i
+option.
+.It Ic .INTERRUPT
+If
+.Nm
+is interrupted, the commands for this target will be executed.
+.It Ic .MAIN
+If no target is specified when
+.Nm
+is invoked, this target will be built.
+.It Ic .MAKEFLAGS
+This target provides a way to specify flags for
+.Nm
+when the makefile is used.
+The flags are as if typed to the shell, though the
+.Fl f
+option will have
+no effect.
+.\" XXX: NOT YET!!!!
+.\" .It Ic .NOTPARALLEL
+.\" The named targets are executed in non parallel mode.
+.\" If no targets are
+.\" specified, then all targets are executed in non parallel mode.
+.It Ic .NOPATH
+Apply the
+.Ic .NOPATH
+attribute to any specified sources.
+.It Ic .NOTPARALLEL
+Disable parallel mode.
+.It Ic .NO_PARALLEL
+Synonym for
+.Ic .NOTPARALLEL ,
+for compatibility with other pmake variants.
+.It Ic .OBJDIR
+The source is a new value for
+.Ql Va .OBJDIR .
+If it exists,
+.Nm
+will
+.Xr chdir 2
+to it and update the value of
+.Ql Va .OBJDIR .
+.It Ic .ORDER
+The named targets are made in sequence.
+This ordering does not add targets to the list of targets to be made.
+Since the dependents of a target do not get built until the target itself
+could be built, unless
+.Ql a
+is built by another part of the dependency graph,
+the following is a dependency loop:
+.Bd -literal
+\&.ORDER: b a
+b: a
+.Ed
+.Pp
+The ordering imposed by
+.Ic .ORDER
+is only relevant for parallel makes.
+.\" XXX: NOT YET!!!!
+.\" .It Ic .PARALLEL
+.\" The named targets are executed in parallel mode.
+.\" If no targets are
+.\" specified, then all targets are executed in parallel mode.
+.It Ic .PATH
+The sources are directories which are to be searched for files not
+found in the current directory.
+If no sources are specified, any previously specified directories are
+deleted.
+If the source is the special
+.Ic .DOTLAST
+target, then the current working
+directory is searched last.
+.It Ic .PATH. Ns Va suffix
+Like
+.Ic .PATH
+but applies only to files with a particular suffix.
+The suffix must have been previously declared with
+.Ic .SUFFIXES .
+.It Ic .PHONY
+Apply the
+.Ic .PHONY
+attribute to any specified sources.
+.It Ic .PRECIOUS
+Apply the
+.Ic .PRECIOUS
+attribute to any specified sources.
+If no sources are specified, the
+.Ic .PRECIOUS
+attribute is applied to every
+target in the file.
+.It Ic .SHELL
+Sets the shell that
+.Nm
+will use to execute commands.
+The sources are a set of
+.Ar field=value
+pairs.
+.Bl -tag -width hasErrCtls
+.It Ar name
+This is the minimal specification, used to select one of the built-in
+shell specs;
+.Ar sh ,
+.Ar ksh ,
+and
+.Ar csh .
+.It Ar path
+Specifies the path to the shell.
+.It Ar hasErrCtl
+Indicates whether the shell supports exit on error.
+.It Ar check
+The command to turn on error checking.
+.It Ar ignore
+The command to disable error checking.
+.It Ar echo
+The command to turn on echoing of commands executed.
+.It Ar quiet
+The command to turn off echoing of commands executed.
+.It Ar filter
+The output to filter after issuing the
+.Ar quiet
+command.
+It is typically identical to
+.Ar quiet .
+.It Ar errFlag
+The flag to pass the shell to enable error checking.
+.It Ar echoFlag
+The flag to pass the shell to enable command echoing.
+.It Ar newline
+The string literal to pass the shell that results in a single newline
+character when used outside of any quoting characters.
+.El
+Example:
+.Bd -literal
+\&.SHELL: name=ksh path=/bin/ksh hasErrCtl=true \e
+ check="set \-e" ignore="set +e" \e
+ echo="set \-v" quiet="set +v" filter="set +v" \e
+ echoFlag=v errFlag=e newline="'\en'"
+.Ed
+.It Ic .SILENT
+Apply the
+.Ic .SILENT
+attribute to any specified sources.
+If no sources are specified, the
+.Ic .SILENT
+attribute is applied to every
+command in the file.
+.It Ic .STALE
+This target gets run when a dependency file contains stale entries, having
+.Va .ALLSRC
+set to the name of that dependency file.
+.It Ic .SUFFIXES
+Each source specifies a suffix to
+.Nm .
+If no sources are specified, any previously specified suffixes are deleted.
+It allows the creation of suffix-transformation rules.
+.Pp
+Example:
+.Bd -literal
+\&.SUFFIXES: .o
+\&.c.o:
+ cc \-o ${.TARGET} \-c ${.IMPSRC}

+.Sh COMPATIBILITY
+The basic make syntax is compatible between different versions of make;
+however the special variables, variable modifiers and conditionals are not.
+.Ss Older versions
+An incomplete list of changes in older versions of
+.Nm :
+.Pp
+The way that .for loop variables are substituted changed after
+NetBSD 5.0
+so that they still appear to be variable expansions.
+In particular this stops them being treated as syntax, and removes some
+obscure problems using them in .if statements.
+.Pp
+The way that parallel makes are scheduled changed in
+NetBSD 4.0
+so that .ORDER and .WAIT apply recursively to the dependent nodes.
+The algorithms used may change again in the future.
+.Ss Other make dialects
+Other make dialects (GNU make, SVR4 make, POSIX make, etc.) do not
+support most of the features of
+.Nm
+as described in this manual.
+Most notably:
+.Bl -bullet -offset indent
+.It
+The
+.Ic .WAIT
+and
+.Ic .ORDER
+declarations and most functionality pertaining to parallelization.
+(GNU make supports parallelization but lacks these features needed to
+control it effectively.)
+.It
+Directives, including for loops and conditionals and most of the
+forms of include files.
+(GNU make has its own incompatible and less powerful syntax for
+conditionals.)
+.It
+All built-in variables that begin with a dot.
+.It
+Most of the special sources and targets that begin with a dot,
+with the notable exception of
+.Ic .PHONY ,
+.Ic .PRECIOUS ,
+and
+.Ic .SUFFIXES .
+.It
+Variable modifiers, except for the
+.Dl :old=new
+string substitution, which does not portably support globbing with
+.Ql %
+and historically only works on declared suffixes.
+.It
+The
+.Ic $>
+variable even in its short form; most makes support this functionality
+but its name varies.
+.El
+.Pp
+Some features are somewhat more portable, such as assignment with
+.Ic += ,
+.Ic ?= ,
+and
+.Ic != .
+The
+.Ic .PATH
+functionality is based on an older feature
+.Ic VPATH
+found in GNU make and many versions of SVR4 make; however,
+historically its behavior is too ill-defined (and too buggy) to rely
+upon.
+.Pp
+The
+.Ic $@
+and
+.Ic $<
+variables are more or less universally portable, as is the
+.Ic $(MAKE)
+variable.
+Basic use of suffix rules (for files only in the current directory,
+not trying to chain transformations together, etc.) is also reasonably
+portable.
+.Sh SEE ALSO
+.Xr mkdep 1
+.Sh HISTORY
+.Nm
+is derived from NetBSD
+.Xr make 1 .
+It uses autoconf to facilitate portability to other platforms.
+.Pp
+A
+make
+command appeared in
+.At v7 .
+This
+make
+implementation is based on Adam De Boor's pmake program which was written
+for Sprite at Berkeley.
+It was designed to be a parallel distributed make running jobs on different
+machines using a daemon called
+.Dq customs .
+.Pp
+Historically the target/dependency
+.Dq FRC
+has been used to FoRCe rebuilding (since the target/dependency
+does not exist... unless someone creates an
+.Dq FRC
+file).
+.Sh BUGS
+The
+make
+syntax is difficult to parse without actually acting of the data.
+For instance finding the end of a variable use should involve scanning each
+the modifiers using the correct terminator for each field.
+In many places
+make
+just counts {} and () in order to find the end of a variable expansion.
+.Pp
+There is no way of escaping a space character in a filename.

-DDEESSCCRRIIPPTTIIOONN
- bbmmaakkee is a program designed to simplify the maintenance of other pro-
- grams. Its input is a list of specifications as to the files upon which
- programs and other files depend. If no --ff _m_a_k_e_f_i_l_e makefile option is
- given, bbmmaakkee will try to open `_m_a_k_e_f_i_l_e' then `_M_a_k_e_f_i_l_e' in order to find
- the specifications. If the file `_._d_e_p_e_n_d' exists, it is read (see
- mkdep(1)).
-
- This manual page is intended as a reference document only. For a more
- thorough description of bbmmaakkee and makefiles, please refer to _P_M_a_k_e _- _A
- _T_u_t_o_r_i_a_l.
-
- bbmmaakkee will prepend the contents of the _M_A_K_E_F_L_A_G_S environment variable to
- the command line arguments before parsing them.
-
- The options are as follows:
-
- --BB Try to be backwards compatible by executing a single shell per
- command and by executing the commands to make the sources of a
- dependency line in sequence.
-
- --CC _d_i_r_e_c_t_o_r_y
- Change to _d_i_r_e_c_t_o_r_y before reading the makefiles or doing any-
- thing else. If multiple --CC options are specified, each is inter-
- preted relative to the previous one: --CC _/ --CC _e_t_c is equivalent to
- --CC _/_e_t_c.
-
- --DD _v_a_r_i_a_b_l_e
- Define _v_a_r_i_a_b_l_e to be 1, in the global context.
-
- --dd _[_-_]_f_l_a_g_s
- Turn on debugging, and specify which portions of bbmmaakkee are to
- print debugging information. Unless the flags are preceded by
- `-' they are added to the _M_A_K_E_F_L_A_G_S environment variable and will
- be processed by any child make processes. By default, debugging
- information is printed to standard error, but this can be changed
- using the _F debugging flag. The debugging output is always
- unbuffered; in addition, if debugging is enabled but debugging
- output is not directed to standard output, then the standard out-
- put is line buffered. _F_l_a_g_s is one or more of the following:
-
- _A Print all possible debugging information; equivalent to
- specifying all of the debugging flags.
-
- _a Print debugging information about archive searching and
- caching.
-
- _C Print debugging information about current working direc-
- tory.
-
- _c Print debugging information about conditional evaluation.
-
- _d Print debugging information about directory searching and
- caching.
-
- _e Print debugging information about failed commands and
- targets.
-
- _F[++]_f_i_l_e_n_a_m_e
- Specify where debugging output is written. This must be
- the last flag, because it consumes the remainder of the
- argument. If the character immediately after the `F'
- flag is `+', then the file will be opened in append mode;
- otherwise the file will be overwritten. If the file name
- is `stdout' or `stderr' then debugging output will be
- written to the standard output or standard error output
- file descriptors respectively (and the `+' option has no
- effect). Otherwise, the output will be written to the
- named file. If the file name ends `.%d' then the `%d' is
- replaced by the pid.
-
- _f Print debugging information about loop evaluation.
-
- _g_1 Print the input graph before making anything.
-
- _g_2 Print the input graph after making everything, or before
- exiting on error.
-
- _g_3 Print the input graph before exiting on error.
-
- _j Print debugging information about running multiple
- shells.
-
- _l Print commands in Makefiles regardless of whether or not
- they are prefixed by `@' or other "quiet" flags. Also
- known as "loud" behavior.
-
- _M Print debugging information about "meta" mode decisions
- about targets.
-
- _m Print debugging information about making targets, includ-
- ing modification dates.
-
- _n Don't delete the temporary command scripts created when
- running commands. These temporary scripts are created in
- the directory referred to by the TMPDIR environment vari-
- able, or in _/_t_m_p if TMPDIR is unset or set to the empty
- string. The temporary scripts are created by mkstemp(3),
- and have names of the form _m_a_k_e_X_X_X_X_X_X. _N_O_T_E: This can
- create many files in TMPDIR or _/_t_m_p, so use with care.
-
- _p Print debugging information about makefile parsing.
-
- _s Print debugging information about suffix-transformation
- rules.
-
- _t Print debugging information about target list mainte-
- nance.
-
- _V Force the --VV option to print raw values of variables.
-
- _v Print debugging information about variable assignment.
-
- _w Print entering and leaving directory messages, pre and
- post processing.
-
- _x Run shell commands with --xx so the actual commands are
- printed as they are executed.
-
- --ee Specify that environment variables override macro assignments
- within makefiles.
-
- --ff _m_a_k_e_f_i_l_e
- Specify a makefile to read instead of the default `_m_a_k_e_f_i_l_e'. If
- _m_a_k_e_f_i_l_e is `--', standard input is read. Multiple makefiles may
- be specified, and are read in the order specified.
-
- --II _d_i_r_e_c_t_o_r_y
- Specify a directory in which to search for makefiles and included
- makefiles. The system makefile directory (or directories, see
- the --mm option) is automatically included as part of this list.
-
- --ii Ignore non-zero exit of shell commands in the makefile. Equiva-
- lent to specifying `--' before each command line in the makefile.
-
- --JJ _p_r_i_v_a_t_e
- This option should _n_o_t be specified by the user.
-
- When the _j option is in use in a recursive build, this option is
- passed by a make to child makes to allow all the make processes
- in the build to cooperate to avoid overloading the system.
-
- --jj _m_a_x___j_o_b_s
- Specify the maximum number of jobs that bbmmaakkee may have running at
- any one time. The value is saved in _._M_A_K_E_._J_O_B_S. Turns compati-
- bility mode off, unless the _B flag is also specified. When com-
- patibility mode is off, all commands associated with a target are
- executed in a single shell invocation as opposed to the tradi-
- tional one shell invocation per line. This can break traditional
- scripts which change directories on each command invocation and
- then expect to start with a fresh environment on the next line.
- It is more efficient to correct the scripts rather than turn
- backwards compatibility on.
-
- --kk Continue processing after errors are encountered, but only on
- those targets that do not depend on the target whose creation
- caused the error.
-
- --mm _d_i_r_e_c_t_o_r_y
- Specify a directory in which to search for sys.mk and makefiles
- included via the <_f_i_l_e>-style include statement. The --mm option
- can be used multiple times to form a search path. This path will
- override the default system include path: /usr/share/mk. Fur-
- thermore the system include path will be appended to the search
- path used for "_f_i_l_e"-style include statements (see the --II
- option).
-
- If a file or directory name in the --mm argument (or the
- MAKESYSPATH environment variable) starts with the string ".../"
- then bbmmaakkee will search for the specified file or directory named
- in the remaining part of the argument string. The search starts
- with the current directory of the Makefile and then works upward
- towards the root of the filesystem. If the search is successful,
- then the resulting directory replaces the ".../" specification in
- the --mm argument. If used, this feature allows bbmmaakkee to easily
- search in the current source tree for customized sys.mk files
- (e.g., by using ".../mk/sys.mk" as an argument).
-
- --nn Display the commands that would have been executed, but do not
- actually execute them unless the target depends on the .MAKE spe-
- cial source (see below).
-
- --NN Display the commands which would have been executed, but do not
- actually execute any of them; useful for debugging top-level
- makefiles without descending into subdirectories.
-
- --qq Do not execute any commands, but exit 0 if the specified targets
- are up-to-date and 1, otherwise.
-
- --rr Do not use the built-in rules specified in the system makefile.
-
- --ss Do not echo any commands as they are executed. Equivalent to
- specifying `@@' before each command line in the makefile.
-
- --TT _t_r_a_c_e_f_i_l_e
- When used with the --jj flag, append a trace record to _t_r_a_c_e_f_i_l_e
- for each job started and completed.
-
- --tt Rather than re-building a target as specified in the makefile,
- create it or update its modification time to make it appear up-
- to-date.
-
- --VV _v_a_r_i_a_b_l_e
- Print bbmmaakkee's idea of the value of _v_a_r_i_a_b_l_e, in the global con-
- text. Do not build any targets. Multiple instances of this
- option may be specified; the variables will be printed one per
- line, with a blank line for each null or undefined variable. If
- _v_a_r_i_a_b_l_e contains a `$' then the value will be expanded before
- printing.
-
- --WW Treat any warnings during makefile parsing as errors.
-
- --XX Don't export variables passed on the command line to the environ-
- ment individually. Variables passed on the command line are
- still exported via the _M_A_K_E_F_L_A_G_S environment variable. This
- option may be useful on systems which have a small limit on the
- size of command arguments.
-
- _v_a_r_i_a_b_l_e_=_v_a_l_u_e
- Set the value of the variable _v_a_r_i_a_b_l_e to _v_a_l_u_e. Normally, all
- values passed on the command line are also exported to sub-makes
- in the environment. The --XX flag disables this behavior. Vari-
- able assignments should follow options for POSIX compatibility
- but no ordering is enforced.
-
- There are seven different types of lines in a makefile: file dependency
- specifications, shell commands, variable assignments, include statements,
- conditional directives, for loops, and comments.
-
- In general, lines may be continued from one line to the next by ending
- them with a backslash (`\'). The trailing newline character and initial
- whitespace on the following line are compressed into a single space.
-

- Dependency lines consist of one or more targets, an operator, and zero or
- more sources. This creates a relationship where the targets ``depend''
- on the sources and are usually created from them. The exact relationship
- between the target and the source is determined by the operator that sep-
- arates them. The three operators are as follows:
-
- :: A target is considered out-of-date if its modification time is less
- than those of any of its sources. Sources for a target accumulate
- over dependency lines when this operator is used. The target is
- removed if bbmmaakkee is interrupted.
-
- !! Targets are always re-created, but not until all sources have been
- examined and re-created as necessary. Sources for a target accumu-
- late over dependency lines when this operator is used. The target
- is removed if bbmmaakkee is interrupted.
-
- :::: If no sources are specified, the target is always re-created. Oth-
- erwise, a target is considered out-of-date if any of its sources
- has been modified more recently than the target. Sources for a
- target do not accumulate over dependency lines when this operator
- is used. The target will not be removed if bbmmaakkee is interrupted.
-
- Targets and sources may contain the shell wildcard values `?', `*', `[]',
- and `{}'. The values `?', `*', and `[]' may only be used as part of the
- final component of the target or source, and must be used to describe
- existing files. The value `{}' need not necessarily be used to describe
- existing files. Expansion is in directory order, not alphabetically as
- done in the shell.
-
-SSHHEELLLL CCOOMMMMAANNDDSS
- Each target may have associated with it a series of shell commands, nor-
- mally used to create the target. Each of the commands in this script
- _m_u_s_t be preceded by a tab. While any target may appear on a dependency
- line, only one of these dependencies may be followed by a creation
- script, unless the `::::' operator is used.
-
- If the first characters of the command line are any combination of `@@',
- `++', or `--', the command is treated specially. A `@@' causes the command
- not to be echoed before it is executed. A `++' causes the command to be
- executed even when --nn is given. This is similar to the effect of the
- .MAKE special source, except that the effect can be limited to a single
- line of a script. A `--' causes any non-zero exit status of the command
- line to be ignored.
-
- When bbmmaakkee is run in jobs mode with --jj _m_a_x___j_o_b_s, the entire script for
- the target is fed to a single instance of the shell.
-
- In compatibility (non-jobs) mode, each command is run in a separate
- process. If the command contains any shell meta characters
- (`#=|^(){};&<>*?[]:$`\\n') it will be passed to the shell, otherwise
- bbmmaakkee will attempt direct execution.
-
- Since bbmmaakkee will chdir(2) to `_._O_B_J_D_I_R' before executing any targets, each
- child process starts with that as its current working directory.
-
- Makefiles should be written so that the mode of bbmmaakkee operation does not
- change their behavior. For example, any command which needs to use
- ``cd'' or ``chdir'', without side-effect should be put in parenthesis:
-
-
- avoid-chdir-side-effects:
- @echo Building $@ in `pwd`
- @(cd ${.CURDIR} && ${.MAKE} $@)
- @echo Back in `pwd`
-
- ensure-one-shell-regardless-of-mode:
- @echo Building $@ in `pwd`; \
- (cd ${.CURDIR} && ${.MAKE} $@); \
- echo Back in `pwd`

- Variables in make are much like variables in the shell, and, by tradi-
- tion, consist of all upper-case letters.
-
- VVaarriiaabbllee aassssiiggnnmmeenntt mmooddiiffiieerrss
- The five operators that can be used to assign values to variables are as
- follows:
-
- == Assign the value to the variable. Any previous value is overrid-
- den.
-
- ++== Append the value to the current value of the variable.
-
- ??== Assign the value to the variable if it is not already defined.
-
- ::== Assign with expansion, i.e. expand the value before assigning it
- to the variable. Normally, expansion is not done until the vari-
- able is referenced. _N_O_T_E: References to undefined variables are
- _n_o_t expanded. This can cause problems when variable modifiers
- are used.
-
- !!== Expand the value and pass it to the shell for execution and
- assign the result to the variable. Any newlines in the result
- are replaced with spaces.
-
- Any white-space before the assigned _v_a_l_u_e is removed; if the value is
- being appended, a single space is inserted between the previous contents
- of the variable and the appended value.
-
- Variables are expanded by surrounding the variable name with either curly
- braces (`{}') or parentheses (`()') and preceding it with a dollar sign
- (`$'). If the variable name contains only a single letter, the surround-
- ing braces or parentheses are not required. This shorter form is not
- recommended.
-
- If the variable name contains a dollar, then the name itself is expanded
- first. This allows almost arbitrary variable names, however names con-
- taining dollar, braces, parenthesis, or whitespace are really best
- avoided!
-
- If the result of expanding a variable contains a dollar sign (`$') the
- string is expanded again.
-
- Variable substitution occurs at three distinct times, depending on where
- the variable is being used.
-
- 1. Variables in dependency lines are expanded as the line is read.
-
- 2. Variables in shell commands are expanded when the shell command is
- executed.
-
- 3. ``.for'' loop index variables are expanded on each loop iteration.
- Note that other variables are not expanded inside loops so the fol-
- lowing example code:
-
-
- .for i in 1 2 3
- a+= ${i}
- j= ${i}
- b+= ${j}
- .endfor
-
- all:
- @echo ${a}
- @echo ${b}
-
- will print:
-
- 1 2 3
- 3 3 3
-
- Because while ${a} contains ``1 2 3'' after the loop is executed,
- ${b} contains ``${j} ${j} ${j}'' which expands to ``3 3 3'' since
- after the loop completes ${j} contains ``3''.
-
- VVaarriiaabbllee ccllaasssseess
- The four different classes of variables (in order of increasing prece-
- dence) are:
-
- Environment variables
- Variables defined as part of bbmmaakkee's environment.
-
- Global variables
- Variables defined in the makefile or in included makefiles.
-
- Command line variables
- Variables defined as part of the command line.
-
- Local variables
- Variables that are defined specific to a certain target. The
- seven local variables are as follows:
-
- _._A_L_L_S_R_C The list of all sources for this target; also known as
- `_>'.
-
- _._A_R_C_H_I_V_E The name of the archive file.
-
- _._I_M_P_S_R_C In suffix-transformation rules, the name/path of the
- source from which the target is to be transformed (the
- ``implied'' source); also known as `_<'. It is not
- defined in explicit rules.
-
- _._M_E_M_B_E_R The name of the archive member.
-
- _._O_O_D_A_T_E The list of sources for this target that were deemed
- out-of-date; also known as `_?'.
-
- _._P_R_E_F_I_X The file prefix of the target, containing only the file
- portion, no suffix or preceding directory components;
- also known as `_*'.
-
- _._T_A_R_G_E_T The name of the target; also known as `_@'.
-
- The shorter forms `_@', `_?', `_<', `_>', and `_*' are permitted for
- backward compatibility with historical makefiles and are not rec-
- ommended. The six variables `_@_F', `_@_D', `_<_F', `_<_D', `_*_F', and
- `_*_D' are permitted for compatibility with AT&T System V UNIX
- makefiles and are not recommended.
-
- Four of the local variables may be used in sources on dependency
- lines because they expand to the proper value for each target on
- the line. These variables are `_._T_A_R_G_E_T', `_._P_R_E_F_I_X', `_._A_R_C_H_I_V_E',
- and `_._M_E_M_B_E_R'.
-
- AAddddiittiioonnaall bbuuiilltt--iinn vvaarriiaabblleess
- In addition, bbmmaakkee sets or knows about the following variables:
-
- _$ A single dollar sign `$', i.e. `$$' expands to a single
- dollar sign.
-
- _._A_L_L_T_A_R_G_E_T_S The list of all targets encountered in the Makefile. If
- evaluated during Makefile parsing, lists only those tar-
- gets encountered thus far.
-
- _._C_U_R_D_I_R A path to the directory where bbmmaakkee was executed. Refer
- to the description of `PWD' for more details.
-
- _._I_N_C_L_U_D_E_D_F_R_O_M_D_I_R
- The directory of the file this Makefile was included
- from.
-
- _._I_N_C_L_U_D_E_D_F_R_O_M_F_I_L_E
- The filename of the file this Makefile was included from.
-
- MAKE The name that bbmmaakkee was executed with (_a_r_g_v_[_0_]). For
- compatibility bbmmaakkee also sets _._M_A_K_E with the same value.
- The preferred variable to use is the environment variable
- MAKE because it is more compatible with other versions of
- bbmmaakkee and cannot be confused with the special target with
- the same name.
-
- _._M_A_K_E_._D_E_P_E_N_D_F_I_L_E
- Names the makefile (default `_._d_e_p_e_n_d') from which gener-
- ated dependencies are read.
-
- _._M_A_K_E_._E_X_P_A_N_D___V_A_R_I_A_B_L_E_S
- A boolean that controls the default behavior of the --VV
- option.
-
- _._M_A_K_E_._E_X_P_O_R_T_E_D The list of variables exported by bbmmaakkee.
-
- _._M_A_K_E_._J_O_B_S The argument to the --jj option.
-
- _._M_A_K_E_._J_O_B_._P_R_E_F_I_X
- If bbmmaakkee is run with _j then output for each target is
- prefixed with a token `--- target ---' the first part of
- which can be controlled via _._M_A_K_E_._J_O_B_._P_R_E_F_I_X. If
- _._M_A_K_E_._J_O_B_._P_R_E_F_I_X is empty, no token is printed.
- For example:
- .MAKE.JOB.PREFIX=${.newline}---${.MAKE:T}[${.MAKE.PID}]
- would produce tokens like `---make[1234] target ---' mak-
- ing it easier to track the degree of parallelism being
- achieved.
-
- MAKEFLAGS The environment variable `MAKEFLAGS' may contain anything
- that may be specified on bbmmaakkee's command line. Anything
- specified on bbmmaakkee's command line is appended to the
- `MAKEFLAGS' variable which is then entered into the envi-
- ronment for all programs which bbmmaakkee executes.
-
- _._M_A_K_E_._L_E_V_E_L The recursion depth of bbmmaakkee. The initial instance of
- bbmmaakkee will be 0, and an incremented value is put into the
- environment to be seen by the next generation. This
- allows tests like: .if ${.MAKE.LEVEL} == 0 to protect
- things which should only be evaluated in the initial
- instance of bbmmaakkee.
-
- _._M_A_K_E_._M_A_K_E_F_I_L_E___P_R_E_F_E_R_E_N_C_E
- The ordered list of makefile names (default `_m_a_k_e_f_i_l_e',
- `_M_a_k_e_f_i_l_e') that bbmmaakkee will look for.
-
- _._M_A_K_E_._M_A_K_E_F_I_L_E_S
- The list of makefiles read by bbmmaakkee, which is useful for
- tracking dependencies. Each makefile is recorded only
- once, regardless of the number of times read.
-
- _._M_A_K_E_._M_O_D_E Processed after reading all makefiles. Can affect the
- mode that bbmmaakkee runs in. It can contain a number of key-
- words:
-
- _c_o_m_p_a_t Like --BB, puts bbmmaakkee into "compat" mode.
-
- _m_e_t_a Puts bbmmaakkee into "meta" mode, where meta files
- are created for each target to capture the
- command run, the output generated and if
- filemon(4) is available, the system calls
- which are of interest to bbmmaakkee. The captured
- output can be very useful when diagnosing
- errors.
-
- _c_u_r_d_i_r_O_k_= _b_f Normally bbmmaakkee will not create .meta files
- in `_._C_U_R_D_I_R'. This can be overridden by set-
- ting _b_f to a value which represents True.
-
- _e_n_v For debugging, it can be useful to inlcude
- the environment in the .meta file.
-
- _v_e_r_b_o_s_e If in "meta" mode, print a clue about the
- target being built. This is useful if the
- build is otherwise running silently. The
- message printed the value of:
- _._M_A_K_E_._M_E_T_A_._P_R_E_F_I_X.
-
- _i_g_n_o_r_e_-_c_m_d Some makefiles have commands which are simply
- not stable. This keyword causes them to be
- ignored for determining whether a target is
- out of date in "meta" mode. See also
- ..NNOOMMEETTAA__CCMMPP.
-
- _s_i_l_e_n_t_= _b_f If _b_f is True, when a .meta file is created,
- mark the target ..SSIILLEENNTT.
-
- _._M_A_K_E_._M_E_T_A_._B_A_I_L_I_W_I_C_K
- In "meta" mode, provides a list of prefixes which match
- the directories controlled by bbmmaakkee. If a file that was
- generated outside of _._O_B_J_D_I_R but within said bailiwick is
- missing, the current target is considered out-of-date.
-
- _._M_A_K_E_._M_E_T_A_._C_R_E_A_T_E_D
- In "meta" mode, this variable contains a list of all the
- meta files updated. If not empty, it can be used to
- trigger processing of _._M_A_K_E_._M_E_T_A_._F_I_L_E_S.
-
- _._M_A_K_E_._M_E_T_A_._F_I_L_E_S
- In "meta" mode, this variable contains a list of all the
- meta files used (updated or not). This list can be used
- to process the meta files to extract dependency informa-
- tion.
-
- _._M_A_K_E_._M_E_T_A_._I_G_N_O_R_E___P_A_T_H_S
- Provides a list of path prefixes that should be ignored;
- because the contents are expected to change over time.
- The default list includes: `_/_d_e_v _/_e_t_c _/_p_r_o_c _/_t_m_p _/_v_a_r_/_r_u_n
- _/_v_a_r_/_t_m_p'
-
- _._M_A_K_E_._M_E_T_A_._P_R_E_F_I_X
- Defines the message printed for each meta file updated in
- "meta verbose" mode. The default value is:
- Building ${.TARGET:H:tA}/${.TARGET:T}
-
- _._M_A_K_E_O_V_E_R_R_I_D_E_S This variable is used to record the names of variables
- assigned to on the command line, so that they may be
- exported as part of `MAKEFLAGS'. This behaviour can be
- disabled by assigning an empty value to `_._M_A_K_E_O_V_E_R_R_I_D_E_S'
- within a makefile. Extra variables can be exported from
- a makefile by appending their names to `_._M_A_K_E_O_V_E_R_R_I_D_E_S'.
- `MAKEFLAGS' is re-exported whenever `_._M_A_K_E_O_V_E_R_R_I_D_E_S' is
- modified.
-
- _._M_A_K_E_._P_A_T_H___F_I_L_E_M_O_N
- If bbmmaakkee was built with filemon(4) support, this is set
- to the path of the device node. This allows makefiles to
- test for this support.
-
- _._M_A_K_E_._P_I_D The process-id of bbmmaakkee.
-
- _._M_A_K_E_._P_P_I_D The parent process-id of bbmmaakkee.
-
- _M_A_K_E___P_R_I_N_T___V_A_R___O_N___E_R_R_O_R
- When bbmmaakkee stops due to an error, it prints its name and
- the value of `_._C_U_R_D_I_R' as well as the value of any vari-
- ables named in `_M_A_K_E___P_R_I_N_T___V_A_R___O_N___E_R_R_O_R'.
-
- _._n_e_w_l_i_n_e This variable is simply assigned a newline character as
- its value. This allows expansions using the ::@@ modifier
- to put a newline between iterations of the loop rather
- than a space. For example, the printing of
- `_M_A_K_E___P_R_I_N_T___V_A_R___O_N___E_R_R_O_R' could be done as
- ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@}.
-
- _._O_B_J_D_I_R A path to the directory where the targets are built. Its
- value is determined by trying to chdir(2) to the follow-
- ing directories in order and using the first match:
-
- 1. ${MAKEOBJDIRPREFIX}${.CURDIR}
-
- (Only if `MAKEOBJDIRPREFIX' is set in the environ-
- ment or on the command line.)
-
- 2. ${MAKEOBJDIR}
-
- (Only if `MAKEOBJDIR' is set in the environment or
- on the command line.)
-
- 3. ${.CURDIR}_/_o_b_j_.${MACHINE}
-
- 4. ${.CURDIR}_/_o_b_j
-
- 5. _/_u_s_r_/_o_b_j_/${.CURDIR}
-
- 6. ${.CURDIR}
-
- Variable expansion is performed on the value before it's
- used, so expressions such as
- ${.CURDIR:S,^/usr/src,/var/obj,}
- may be used. This is especially useful with
- `MAKEOBJDIR'.
-
- `_._O_B_J_D_I_R' may be modified in the makefile as a global
- variable. In all cases, bbmmaakkee will chdir(2) to `_._O_B_J_D_I_R'
- and set `PWD' to that directory before executing any tar-
- gets.
-
- _._P_A_R_S_E_D_I_R A path to the directory of the current `_M_a_k_e_f_i_l_e' being
- parsed.
-
- _._P_A_R_S_E_F_I_L_E The basename of the current `_M_a_k_e_f_i_l_e' being parsed.
- This variable and `_._P_A_R_S_E_D_I_R' are both set only while the
- `_M_a_k_e_f_i_l_e_s' are being parsed. If you want to retain
- their current values, assign them to a variable using
- assignment with expansion: (`::==').
-
- _._P_A_T_H A variable that represents the list of directories that
- bbmmaakkee will search for files. The search list should be
- updated using the target `_._P_A_T_H' rather than the vari-
- able.
-
- PWD Alternate path to the current directory. bbmmaakkee normally
- sets `_._C_U_R_D_I_R' to the canonical path given by getcwd(3).
- However, if the environment variable `PWD' is set and
- gives a path to the current directory, then bbmmaakkee sets
- `_._C_U_R_D_I_R' to the value of `PWD' instead. This behaviour
- is disabled if `MAKEOBJDIRPREFIX' is set or `MAKEOBJDIR'
- contains a variable transform. `PWD' is set to the value
- of `_._O_B_J_D_I_R' for all programs which bbmmaakkee executes.
-
- .TARGETS The list of targets explicitly specified on the command
- line, if any.
-
- VPATH Colon-separated (``:'') lists of directories that bbmmaakkee
- will search for files. The variable is supported for
- compatibility with old make programs only, use `_._P_A_T_H'
- instead.
-
- VVaarriiaabbllee mmooddiiffiieerrss
- Variable expansion may be modified to select or modify each word of the
- variable (where a ``word'' is white-space delimited sequence of charac-
- ters). The general format of a variable expansion is as follows:
-
- ${variable[:modifier[:...]]}
-
- Each modifier begins with a colon, which may be escaped with a backslash
- (`\').
-
- A set of modifiers can be specified via a variable, as follows:
-
- modifier_variable=modifier[:...]
- ${variable:${modifier_variable}[:...]}
-
- In this case the first modifier in the modifier_variable does not start
- with a colon, since that must appear in the referencing variable. If any
- of the modifiers in the modifier_variable contain a dollar sign (`$'),
- these must be doubled to avoid early expansion.
-
- The supported modifiers are:
-
- ::EE Replaces each word in the variable with its suffix.
-
- ::HH Replaces each word in the variable with everything but the last com-
- ponent.
-
- ::MM_p_a_t_t_e_r_n
- Select only those words that match _p_a_t_t_e_r_n. The standard shell
- wildcard characters (`*', `?', and `[]') may be used. The wildcard
- characters may be escaped with a backslash (`\'). As a consequence
- of the way values are split into words, matched, and then joined, a
- construct like
- ${VAR:M*}
- will normalise the inter-word spacing, removing all leading and
- trailing space, and converting multiple consecutive spaces to single
- spaces.
-
- ::NN_p_a_t_t_e_r_n
- This is identical to `::MM', but selects all words which do not match
- _p_a_t_t_e_r_n.
-
- ::OO Order every word in variable alphabetically. To sort words in
- reverse order use the `::OO::[[--11....11]]' combination of modifiers.
-
- ::OOxx Randomize words in variable. The results will be different each
- time you are referring to the modified variable; use the assignment
- with expansion (`::==') to prevent such behaviour. For example,
-
- LIST= uno due tre quattro
- RANDOM_LIST= ${LIST:Ox}
- STATIC_RANDOM_LIST:= ${LIST:Ox}
-
- all:
- @echo "${RANDOM_LIST}"
- @echo "${RANDOM_LIST}"
- @echo "${STATIC_RANDOM_LIST}"
- @echo "${STATIC_RANDOM_LIST}"
- may produce output similar to:
-
- quattro due tre uno
- tre due quattro uno
- due uno quattro tre
- due uno quattro tre
-
- ::QQ Quotes every shell meta-character in the variable, so that it can be
- passed safely through recursive invocations of bbmmaakkee.
-
- ::RR Replaces each word in the variable with everything but its suffix.
-
- ::ggmmttiimmee
- The value is a format string for strftime(3), using the current
- gmtime(3).
-
- ::hhaasshh
- Compute a 32bit hash of the value and encode it as hex digits.
-
- ::llooccaallttiimmee
- The value is a format string for strftime(3), using the current
- localtime(3).
-
- ::ttAA Attempt to convert variable to an absolute path using realpath(3),
- if that fails, the value is unchanged.
-
- ::ttll Converts variable to lower-case letters.
-
- ::ttss_c
- Words in the variable are normally separated by a space on expan-
- sion. This modifier sets the separator to the character _c. If _c is
- omitted, then no separator is used. The common escapes (including
- octal numeric codes), work as expected.
-
- ::ttuu Converts variable to upper-case letters.
-
- ::ttWW Causes the value to be treated as a single word (possibly containing
- embedded white space). See also `::[[**]]'.
-
- ::ttww Causes the value to be treated as a sequence of words delimited by
- white space. See also `::[[@@]]'.
-
- ::SS/_o_l_d___s_t_r_i_n_g/_n_e_w___s_t_r_i_n_g/[11ggWW]
- Modify the first occurrence of _o_l_d___s_t_r_i_n_g in the variable's value,
- replacing it with _n_e_w___s_t_r_i_n_g. If a `g' is appended to the last
- slash of the pattern, all occurrences in each word are replaced. If
- a `1' is appended to the last slash of the pattern, only the first
- word is affected. If a `W' is appended to the last slash of the
- pattern, then the value is treated as a single word (possibly con-
- taining embedded white space). If _o_l_d___s_t_r_i_n_g begins with a caret
- (`^'), _o_l_d___s_t_r_i_n_g is anchored at the beginning of each word. If
- _o_l_d___s_t_r_i_n_g ends with a dollar sign (`$'), it is anchored at the end
- of each word. Inside _n_e_w___s_t_r_i_n_g, an ampersand (`&') is replaced by
- _o_l_d___s_t_r_i_n_g (without any `^' or `$'). Any character may be used as a
- delimiter for the parts of the modifier string. The anchoring,
- ampersand and delimiter characters may be escaped with a backslash
- (`\').
-
- Variable expansion occurs in the normal fashion inside both
- _o_l_d___s_t_r_i_n_g and _n_e_w___s_t_r_i_n_g with the single exception that a backslash
- is used to prevent the expansion of a dollar sign (`$'), not a pre-
- ceding dollar sign as is usual.
-
- ::CC/_p_a_t_t_e_r_n/_r_e_p_l_a_c_e_m_e_n_t/[11ggWW]
- The ::CC modifier is just like the ::SS modifier except that the old and
- new strings, instead of being simple strings, are an extended regu-
- lar expression (see regex(3)) string _p_a_t_t_e_r_n and an ed(1)-style
- string _r_e_p_l_a_c_e_m_e_n_t. Normally, the first occurrence of the pattern
- _p_a_t_t_e_r_n in each word of the value is substituted with _r_e_p_l_a_c_e_m_e_n_t.
- The `1' modifier causes the substitution to apply to at most one
- word; the `g' modifier causes the substitution to apply to as many
- instances of the search pattern _p_a_t_t_e_r_n as occur in the word or
- words it is found in; the `W' modifier causes the value to be
- treated as a single word (possibly containing embedded white space).
- Note that `1' and `g' are orthogonal; the former specifies whether
- multiple words are potentially affected, the latter whether multiple
- substitutions can potentially occur within each affected word.
-
- As for the ::SS modifier, the _p_a_t_t_e_r_n and _r_e_p_l_a_c_e_m_e_n_t are subjected to
- variable expansion before being parsed as regular expressions.
-
- ::TT Replaces each word in the variable with its last component.
-
- ::uu Remove adjacent duplicate words (like uniq(1)).
-
- ::??_t_r_u_e___s_t_r_i_n_g::_f_a_l_s_e___s_t_r_i_n_g
- If the variable name (not its value), when parsed as a .if condi-
- tional expression, evaluates to true, return as its value the
- _t_r_u_e___s_t_r_i_n_g, otherwise return the _f_a_l_s_e___s_t_r_i_n_g. Since the variable
- name is used as the expression, :? must be the first modifier after
- the variable name itself - which will, of course, usually contain
- variable expansions. A common error is trying to use expressions
- like
- ${NUMBERS:M42:?match:no}
- which actually tests defined(NUMBERS), to determine is any words
- match "42" you need to use something like:
- ${"${NUMBERS:M42}" != "":?match:no}.
-
- _:_o_l_d___s_t_r_i_n_g_=_n_e_w___s_t_r_i_n_g
- This is the AT&T System V UNIX style variable substitution. It must
- be the last modifier specified. If _o_l_d___s_t_r_i_n_g or _n_e_w___s_t_r_i_n_g do not
- contain the pattern matching character _% then it is assumed that
- they are anchored at the end of each word, so only suffixes or
- entire words may be replaced. Otherwise _% is the substring of
- _o_l_d___s_t_r_i_n_g to be replaced in _n_e_w___s_t_r_i_n_g.
-
- Variable expansion occurs in the normal fashion inside both
- _o_l_d___s_t_r_i_n_g and _n_e_w___s_t_r_i_n_g with the single exception that a backslash
- is used to prevent the expansion of a dollar sign (`$'), not a pre-
- ceding dollar sign as is usual.
-
- ::@@_t_e_m_p@@_s_t_r_i_n_g@@
- This is the loop expansion mechanism from the OSF Development Envi-
- ronment (ODE) make. Unlike ..ffoorr loops expansion occurs at the time
- of reference. Assign _t_e_m_p to each word in the variable and evaluate
- _s_t_r_i_n_g. The ODE convention is that _t_e_m_p should start and end with a
- period. For example.
- ${LINKS:@.LINK.@${LN} ${TARGET} ${.LINK.}@}
-
- However a single character variable is often more readable:
- ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@}
-
- ::UU_n_e_w_v_a_l
- If the variable is undefined _n_e_w_v_a_l is the value. If the variable
- is defined, the existing value is returned. This is another ODE
- make feature. It is handy for setting per-target CFLAGS for
- instance:
- ${_${.TARGET:T}_CFLAGS:U${DEF_CFLAGS}}
- If a value is only required if the variable is undefined, use:
- ${VAR:D:Unewval}
-
- ::DD_n_e_w_v_a_l
- If the variable is defined _n_e_w_v_a_l is the value.
-
- ::LL The name of the variable is the value.
-
- ::PP The path of the node which has the same name as the variable is the
- value. If no such node exists or its path is null, then the name of
- the variable is used. In order for this modifier to work, the name
- (node) must at least have appeared on the rhs of a dependency.
-
- ::!!_c_m_d!!
- The output of running _c_m_d is the value.
-
- ::sshh If the variable is non-empty it is run as a command and the output
- becomes the new value.
-
- ::::==_s_t_r
- The variable is assigned the value _s_t_r after substitution. This
- modifier and its variations are useful in obscure situations such as
- wanting to set a variable when shell commands are being parsed.
- These assignment modifiers always expand to nothing, so if appearing
- in a rule line by themselves should be preceded with something to
- keep bbmmaakkee happy.
-
- The `::::' helps avoid false matches with the AT&T System V UNIX style
- ::== modifier and since substitution always occurs the ::::== form is
- vaguely appropriate.
-
- ::::??==_s_t_r
- As for ::::== but only if the variable does not already have a value.
-
- ::::++==_s_t_r
- Append _s_t_r to the variable.
-
- ::::!!==_c_m_d
- Assign the output of _c_m_d to the variable.
-
- ::[[_r_a_n_g_e]]
- Selects one or more words from the value, or performs other opera-
- tions related to the way in which the value is divided into words.
-
- Ordinarily, a value is treated as a sequence of words delimited by
- white space. Some modifiers suppress this behaviour, causing a
- value to be treated as a single word (possibly containing embedded
- white space). An empty value, or a value that consists entirely of
- white-space, is treated as a single word. For the purposes of the
- `::[[]]' modifier, the words are indexed both forwards using positive
- integers (where index 1 represents the first word), and backwards
- using negative integers (where index -1 represents the last word).
-
- The _r_a_n_g_e is subjected to variable expansion, and the expanded
- result is then interpreted as follows:
-
- _i_n_d_e_x Selects a single word from the value.
-
- _s_t_a_r_t...._e_n_d
- Selects all words from _s_t_a_r_t to _e_n_d, inclusive. For example,
- `::[[22....--11]]' selects all words from the second word to the last
- word. If _s_t_a_r_t is greater than _e_n_d, then the words are out-
- put in reverse order. For example, `::[[--11....11]]' selects all
- the words from last to first.
-
- ** Causes subsequent modifiers to treat the value as a single
- word (possibly containing embedded white space). Analogous
- to the effect of "$*" in Bourne shell.
-
- 0 Means the same as `::[[**]]'.
-
- @@ Causes subsequent modifiers to treat the value as a sequence
- of words delimited by white space. Analogous to the effect
- of "$@" in Bourne shell.
-
- ## Returns the number of words in the value.

-IINNCCLLUUDDEE SSTTAATTEEMMEENNTTSS,, CCOONNDDIITTIIOONNAALLSS AANNDD FFOORR LLOOOOPPSS
- Makefile inclusion, conditional structures and for loops reminiscent of
- the C programming language are provided in bbmmaakkee. All such structures
- are identified by a line beginning with a single dot (`.') character.
- Files are included with either ..iinncclluuddee <_f_i_l_e> or ..iinncclluuddee "_f_i_l_e". Vari-
- ables between the angle brackets or double quotes are expanded to form
- the file name. If angle brackets are used, the included makefile is
- expected to be in the system makefile directory. If double quotes are
- used, the including makefile's directory and any directories specified
- using the --II option are searched before the system makefile directory.
- For compatibility with other versions of bbmmaakkee `include file ...' is also
- accepted. If the include statement is written as ..--iinncclluuddee or as
- ..ssiinncclluuddee then errors locating and/or opening include files are ignored.
-
- Conditional expressions are also preceded by a single dot as the first
- character of a line. The possible conditionals are as follows:
-
- ..eerrrroorr _m_e_s_s_a_g_e
- The message is printed along with the name of the makefile and
- line number, then bbmmaakkee will exit.
-
- ..eexxppoorrtt _v_a_r_i_a_b_l_e _._._.
- Export the specified global variable. If no variable list is
- provided, all globals are exported except for internal variables
- (those that start with `.'). This is not affected by the --XX
- flag, so should be used with caution. For compatibility with
- other bbmmaakkee programs `export variable=value' is also accepted.
-
- Appending a variable name to _._M_A_K_E_._E_X_P_O_R_T_E_D is equivalent to
- exporting a variable.
-
- ..eexxppoorrtt--eennvv _v_a_r_i_a_b_l_e _._._.
- The same as `.export', except that the variable is not appended
- to _._M_A_K_E_._E_X_P_O_R_T_E_D. This allows exporting a value to the environ-
- ment which is different from that used by bbmmaakkee internally.
-
- ..iinnffoo _m_e_s_s_a_g_e
- The message is printed along with the name of the makefile and
- line number.
-
- ..uunnddeeff _v_a_r_i_a_b_l_e
- Un-define the specified global variable. Only global variables
- may be un-defined.
-
- ..uunneexxppoorrtt _v_a_r_i_a_b_l_e _._._.
- The opposite of `.export'. The specified global _v_a_r_i_a_b_l_e will be
- removed from _._M_A_K_E_._E_X_P_O_R_T_E_D. If no variable list is provided,
- all globals are unexported, and _._M_A_K_E_._E_X_P_O_R_T_E_D deleted.
-
- ..uunneexxppoorrtt--eennvv
- Unexport all globals previously exported and clear the environ-
- ment inherited from the parent. This operation will cause a mem-
- ory leak of the original environment, so should be used spar-
- ingly. Testing for _._M_A_K_E_._L_E_V_E_L being 0, would make sense. Also
- note that any variables which originated in the parent environ-
- ment should be explicitly preserved if desired. For example:
-
- .if ${.MAKE.LEVEL} == 0
- PATH := ${PATH}
- .unexport-env
- .export PATH
- .endif
-
- Would result in an environment containing only `PATH', which is
- the minimal useful environment. Actually `.MAKE.LEVEL' will also
- be pushed into the new environment.
-
- ..wwaarrnniinngg _m_e_s_s_a_g_e
- The message prefixed by `_w_a_r_n_i_n_g_:' is printed along with the name
- of the makefile and line number.
-
- ..iiff [!]_e_x_p_r_e_s_s_i_o_n [_o_p_e_r_a_t_o_r _e_x_p_r_e_s_s_i_o_n _._._.]
- Test the value of an expression.
-
- ..iiffddeeff [!]_v_a_r_i_a_b_l_e [_o_p_e_r_a_t_o_r _v_a_r_i_a_b_l_e _._._.]
- Test the value of a variable.

- ..iiffnnddeeff [!]_v_a_r_i_a_b_l_e [_o_p_e_r_a_t_o_r _v_a_r_i_a_b_l_e _._._.]

-
- ..iiffmmaakkee [!]_t_a_r_g_e_t [_o_p_e_r_a_t_o_r _t_a_r_g_e_t _._._.]

-
- ..iiffnnmmaakkee [!] _t_a_r_g_e_t [_o_p_e_r_a_t_o_r _t_a_r_g_e_t _._._.]
- Test the target being built.

-
- ..eelliiff [!] _e_x_p_r_e_s_s_i_o_n [_o_p_e_r_a_t_o_r _e_x_p_r_e_s_s_i_o_n _._._.]
- A combination of `..eellssee' followed by `..iiff'.
-
- ..eelliiffddeeff [!]_v_a_r_i_a_b_l_e [_o_p_e_r_a_t_o_r _v_a_r_i_a_b_l_e _._._.]
- A combination of `..eellssee' followed by `..iiffddeeff'.
-
- ..eelliiffnnddeeff [!]_v_a_r_i_a_b_l_e [_o_p_e_r_a_t_o_r _v_a_r_i_a_b_l_e _._._.]

-
- ..eelliiffmmaakkee [!]_t_a_r_g_e_t [_o_p_e_r_a_t_o_r _t_a_r_g_e_t _._._.]

-
- ..eelliiffnnmmaakkee [!]_t_a_r_g_e_t [_o_p_e_r_a_t_o_r _t_a_r_g_e_t _._._.]
- A combination of `..eellssee' followed by `..iiffnnmmaakkee'.
-
- ..eennddiiff End the body of the conditional.
-
- The _o_p_e_r_a_t_o_r may be any one of the following:
-
- |||| Logical OR.
-
- &&&& Logical AND; of higher precedence than ``||''.
-
- As in C, bbmmaakkee will only evaluate a conditional as far as is necessary to
- determine its value. Parentheses may be used to change the order of
- evaluation. The boolean operator `!!' may be used to logically negate an
- entire conditional. It is of higher precedence than `&&&&'.
-
- The value of _e_x_p_r_e_s_s_i_o_n may be any of the following:
-
- ddeeffiinneedd Takes a variable name as an argument and evaluates to true if
- the variable has been defined.
-
- mmaakkee Takes a target name as an argument and evaluates to true if the
- target was specified as part of bbmmaakkee's command line or was
- declared the default target (either implicitly or explicitly,
- see _._M_A_I_N) before the line containing the conditional.
-
- eemmppttyy Takes a variable, with possible modifiers, and evaluates to true
- if the expansion of the variable would result in an empty
- string.
-
- eexxiissttss Takes a file name as an argument and evaluates to true if the
- file exists. The file is searched for on the system search path
- (see _._P_A_T_H).
-
- ttaarrggeett Takes a target name as an argument and evaluates to true if the
- target has been defined.
-
- ccoommmmaannddss
- Takes a target name as an argument and evaluates to true if the
- target has been defined and has commands associated with it.
-
- _E_x_p_r_e_s_s_i_o_n may also be an arithmetic or string comparison. Variable
- expansion is performed on both sides of the comparison, after which the
- integral values are compared. A value is interpreted as hexadecimal if
- it is preceded by 0x, otherwise it is decimal; octal numbers are not sup-
- ported. The standard C relational operators are all supported. If after
- variable expansion, either the left or right hand side of a `====' or `!!=='
- operator is not an integral value, then string comparison is performed
- between the expanded variables. If no relational operator is given, it
- is assumed that the expanded variable is being compared against 0 or an
- empty string in the case of a string comparison.
-
- When bbmmaakkee is evaluating one of these conditional expressions, and it
- encounters a (white-space separated) word it doesn't recognize, either
- the ``make'' or ``defined'' expression is applied to it, depending on the
- form of the conditional. If the form is `..iiffddeeff', `..iiffnnddeeff', or `..iiff'
- the ``defined'' expression is applied. Similarly, if the form is
- `..iiffmmaakkee' or `..iiffnnmmaakkee, tthhee' ``make'' expression is applied.
-
- If the conditional evaluates to true the parsing of the makefile contin-
- ues as before. If it evaluates to false, the following lines are
- skipped. In both cases this continues until a `..eellssee' or `..eennddiiff' is
- found.
-
- For loops are typically used to apply a set of rules to a list of files.
- The syntax of a for loop is:
-
- ..ffoorr _v_a_r_i_a_b_l_e [_v_a_r_i_a_b_l_e _._._.] iinn _e_x_p_r_e_s_s_i_o_n
- <make-rules>
- ..eennddffoorr
-
- After the for eexxpprreessssiioonn is evaluated, it is split into words. On each
- iteration of the loop, one word is taken and assigned to each vvaarriiaabbllee,
- in order, and these vvaarriiaabblleess are substituted into the mmaakkee--rruulleess inside
- the body of the for loop. The number of words must come out even; that
- is, if there are three iteration variables, the number of words provided
- must be a multiple of three.
-
-CCOOMMMMEENNTTSS
- Comments begin with a hash (`#') character, anywhere but in a shell com-
- mand line, and continue to the end of an unescaped new line.
-
-SSPPEECCIIAALL SSOOUURRCCEESS ((AATTTTRRIIBBUUTTEESS))
- ..EEXXEECC Target is never out of date, but always execute commands any-
- way.
-
- ..IIGGNNOORREE Ignore any errors from the commands associated with this tar-
- get, exactly as if they all were preceded by a dash (`-').
-
- ..MMAADDEE Mark all sources of this target as being up-to-date.
-
- ..MMAAKKEE Execute the commands associated with this target even if the --nn
- or --tt options were specified. Normally used to mark recursive
- bbmmaakkees.
-
- ..MMEETTAA Create a meta file for the target, even if it is flagged as
- ..PPHHOONNYY, ..MMAAKKEE, or ..SSPPEECCIIAALL. Usage in conjunction with ..MMAAKKEE is
- the most likely case. In "meta" mode, the target is out-of-
- date if the meta file is missing.
-
- ..NNOOMMEETTAA Do not create a meta file for the target. Meta files are also
- not created for ..PPHHOONNYY, ..MMAAKKEE, or ..SSPPEECCIIAALL targets.
-
- ..NNOOMMEETTAA__CCMMPP
- Ignore differences in commands when deciding if target is out
- of date. This is useful if the command contains a value which
- always changes. If the number of commands change, though, the
- target will still be out of date. The same effect applies to
- any command line that uses the variable _._O_O_D_A_T_E, which can be
- used for that purpose even when not otherwise needed or
- desired:
-
-
- skip-compare-for-some:
- @echo this will be compared
- @echo this will not ${.OODATE:M.NOMETA_CMP}
- @echo this will also be compared
-
- The ::MM pattern suppresses any expansion of the unwanted vari-
- able.
-
- ..NNOOPPAATTHH Do not search for the target in the directories specified by
- ..PPAATTHH.
-
- ..NNOOTTMMAAIINN Normally bbmmaakkee selects the first target it encounters as the
- default target to be built if no target was specified. This
- source prevents this target from being selected.
-
- ..OOPPTTIIOONNAALL
- If a target is marked with this attribute and bbmmaakkee can't fig-
- ure out how to create it, it will ignore this fact and assume
- the file isn't needed or already exists.
-
- ..PPHHOONNYY The target does not correspond to an actual file; it is always
- considered to be out of date, and will not be created with the
- --tt option. Suffix-transformation rules are not applied to
- ..PPHHOONNYY targets.
-
- ..PPRREECCIIOOUUSS
- When bbmmaakkee is interrupted, it normally removes any partially
- made targets. This source prevents the target from being
- removed.
-
- ..RREECCUURRSSIIVVEE
- Synonym for ..MMAAKKEE.
-
- ..SSIILLEENNTT Do not echo any of the commands associated with this target,
- exactly as if they all were preceded by an at sign (`@').
-
- ..UUSSEE Turn the target into bbmmaakkee's version of a macro. When the tar-
- get is used as a source for another target, the other target
- acquires the commands, sources, and attributes (except for
- ..UUSSEE) of the source. If the target already has commands, the
- ..UUSSEE target's commands are appended to them.
-
- ..UUSSEEBBEEFFOORREE
- Exactly like ..UUSSEE, but prepend the ..UUSSEEBBEEFFOORREE target commands
- to the target.
-
- ..WWAAIITT If ..WWAAIITT appears in a dependency line, the sources that precede
- it are made before the sources that succeed it in the line.
- Since the dependents of files are not made until the file
- itself could be made, this also stops the dependents being
- built unless they are needed for another branch of the depen-
- dency tree. So given:
-
- x: a .WAIT b
- echo x
- a:
- echo a
- b: b1
- echo b
- b1:
- echo b1
-
- the output is always `a', `b1', `b', `x'.
- The ordering imposed by ..WWAAIITT is only relevant for parallel
- makes.
-
-SSPPEECCIIAALL TTAARRGGEETTSS
- Special targets may not be included with other targets, i.e. they must be
- the only target specified.
-
- ..BBEEGGIINN Any command lines attached to this target are executed before
- anything else is done.
-
- ..DDEEFFAAUULLTT
- This is sort of a ..UUSSEE rule for any target (that was used only
- as a source) that bbmmaakkee can't figure out any other way to cre-
- ate. Only the shell script is used. The ..IIMMPPSSRRCC variable of a
- target that inherits ..DDEEFFAAUULLTT's commands is set to the target's
- own name.
-
- ..EENNDD Any command lines attached to this target are executed after
- everything else is done.
-
- ..EERRRROORR Any command lines attached to this target are executed when
- another target fails. The ..EERRRROORR__TTAARRGGEETT variable is set to the
- target that failed. See also MMAAKKEE__PPRRIINNTT__VVAARR__OONN__EERRRROORR.
-
- ..IIGGNNOORREE Mark each of the sources with the ..IIGGNNOORREE attribute. If no
- sources are specified, this is the equivalent of specifying the
- --ii option.
-
- ..IINNTTEERRRRUUPPTT
- If bbmmaakkee is interrupted, the commands for this target will be
- executed.
-
- ..MMAAIINN If no target is specified when bbmmaakkee is invoked, this target
- will be built.
-
- ..MMAAKKEEFFLLAAGGSS
- This target provides a way to specify flags for bbmmaakkee when the
- makefile is used. The flags are as if typed to the shell,
- though the --ff option will have no effect.
-
- ..NNOOPPAATTHH Apply the ..NNOOPPAATTHH attribute to any specified sources.
-
- ..NNOOTTPPAARRAALLLLEELL
- Disable parallel mode.
-
- ..NNOO__PPAARRAALLLLEELL
- Synonym for ..NNOOTTPPAARRAALLLLEELL, for compatibility with other pmake
- variants.
-
- ..OORRDDEERR The named targets are made in sequence. This ordering does not
- add targets to the list of targets to be made. Since the depen-
- dents of a target do not get built until the target itself could
- be built, unless `a' is built by another part of the dependency
- graph, the following is a dependency loop:
-
- .ORDER: b a
- b: a
-
- The ordering imposed by ..OORRDDEERR is only relevant for parallel
- makes.
-
- ..PPAATTHH The sources are directories which are to be searched for files
- not found in the current directory. If no sources are speci-
- fied, any previously specified directories are deleted. If the
- source is the special ..DDOOTTLLAASSTT target, then the current working
- directory is searched last.
-
- ..PPAATTHH.._s_u_f_f_i_x
- Like ..PPAATTHH but applies only to files with a particular suffix.
- The suffix must have been previously declared with ..SSUUFFFFIIXXEESS.
-
- ..PPHHOONNYY Apply the ..PPHHOONNYY attribute to any specified sources.
-
- ..PPRREECCIIOOUUSS
- Apply the ..PPRREECCIIOOUUSS attribute to any specified sources. If no
- sources are specified, the ..PPRREECCIIOOUUSS attribute is applied to
- every target in the file.
-
- ..SSHHEELLLL Sets the shell that bbmmaakkee will use to execute commands. The
- sources are a set of _f_i_e_l_d_=_v_a_l_u_e pairs.
-
- _n_a_m_e This is the minimal specification, used to select
- one of the builtin shell specs; _s_h, _k_s_h, and _c_s_h.
-
- _p_a_t_h Specifies the path to the shell.
-
- _h_a_s_E_r_r_C_t_l Indicates whether the shell supports exit on error.
-
- _c_h_e_c_k The command to turn on error checking.
-
- _i_g_n_o_r_e The command to disable error checking.
-
- _e_c_h_o The command to turn on echoing of commands executed.
-
- _q_u_i_e_t The command to turn off echoing of commands exe-
- cuted.
-
- _f_i_l_t_e_r The output to filter after issuing the _q_u_i_e_t com-
- mand. It is typically identical to _q_u_i_e_t.
-
- _e_r_r_F_l_a_g The flag to pass the shell to enable error checking.
-
- _e_c_h_o_F_l_a_g The flag to pass the shell to enable command echo-
- ing.
-
- _n_e_w_l_i_n_e The string literal to pass the shell that results in
- a single newline character when used outside of any
- quoting characters.
- Example:
-
- .SHELL: name=ksh path=/bin/ksh hasErrCtl=true \
- check="set -e" ignore="set +e" \
- echo="set -v" quiet="set +v" filter="set +v" \
- echoFlag=v errFlag=e newline="'\n'"
-
- ..SSIILLEENNTT Apply the ..SSIILLEENNTT attribute to any specified sources. If no
- sources are specified, the ..SSIILLEENNTT attribute is applied to every
- command in the file.
-
- ..SSTTAALLEE This target gets run when a dependency file contains stale
- entries, having _._A_L_L_S_R_C set to the name of that dependency file.
-
- ..SSUUFFFFIIXXEESS
- Each source specifies a suffix to bbmmaakkee. If no sources are
- specified, any previously specified suffixes are deleted. It
- allows the creation of suffix-transformation rules.

- bbmmaakkee uses the following environment variables, if they exist: MACHINE,
- MACHINE_ARCH, MAKE, MAKEFLAGS, MAKEOBJDIR, MAKEOBJDIRPREFIX, MAKESYSPATH,
- PWD, and TMPDIR.
-
- MAKEOBJDIRPREFIX and MAKEOBJDIR may only be set in the environment or on
- the command line to bbmmaakkee and not as makefile variables; see the descrip-
- tion of `_._O_B_J_D_I_R' for more details.

- The basic make syntax is compatible between different versions of make,
- however the special variables, variable modifiers and conditionals are
- not.

- The way that parallel makes are scheduled changed in NetBSD 4.0 so that
- .ORDER and .WAIT apply recursively to the dependent nodes. The algo-
- rithms used may change again in the future.
-
- The way that .for loop variables are substituted changed after NetBSD 5.0
- so that they still appear to be variable expansions. In particular this
- stops them being treated as syntax, and removes some obscure problems
- using them in .if statements.

- bbmmaakkee is derived from NetBSD make(1). It uses autoconf to facilitate
- portability to other platforms.
-
- A make command appeared in Version 7 AT&T UNIX. This make implementation
- is based on Adam De Boor's pmake program which was written for Sprite at
- Berkeley. It was designed to be a parallel distributed make running jobs
- on different machines using a daemon called ``customs''.
-
- Historically the target/dependency ``FRC'' has been used to FoRCe
- rebuilding (since the target/dependency does not exist... unless someone
- creates an ``FRC'' file).
-
-BBUUGGSS
- The make syntax is difficult to parse without actually acting of the
- data. For instance finding the end of a variable use should involve
- scanning each the modifiers using the correct terminator for each field.
- In many places make just counts {} and () in order to find the end of a
- variable expansion.
-
- There is no way of escaping a space character in a filename.

+ bbmmaakkee is a program designed to simplify the maintenance of other pro-
+ grams. Its input is a list of specifications as to the files upon which
+ programs and other files depend. If no --ff _m_a_k_e_f_i_l_e makefile option is
+ given, bbmmaakkee will try to open `_m_a_k_e_f_i_l_e' then `_M_a_k_e_f_i_l_e' in order to find
+ the specifications. If the file `_._d_e_p_e_n_d' exists, it is read (see
+ mkdep(1)).
+
+ This manual page is intended as a reference document only. For a more
+ thorough description of bbmmaakkee and makefiles, please refer to _P_M_a_k_e _- _A
+ _T_u_t_o_r_i_a_l.
+
+ bbmmaakkee will prepend the contents of the _M_A_K_E_F_L_A_G_S environment variable to
+ the command line arguments before parsing them.
+
+ The options are as follows:
+
+ --BB Try to be backwards compatible by executing a single shell per
+ command and by executing the commands to make the sources of a
+ dependency line in sequence.
+
+ --CC _d_i_r_e_c_t_o_r_y
+ Change to _d_i_r_e_c_t_o_r_y before reading the makefiles or doing any-
+ thing else. If multiple --CC options are specified, each is inter-
+ preted relative to the previous one: --CC _/ --CC _e_t_c is equivalent to
+ --CC _/_e_t_c.
+
+ --DD _v_a_r_i_a_b_l_e
+ Define _v_a_r_i_a_b_l_e to be 1, in the global context.
+
+ --dd _[_-_]_f_l_a_g_s
+ Turn on debugging, and specify which portions of bbmmaakkee are to
+ print debugging information. Unless the flags are preceded by
+ `-' they are added to the _M_A_K_E_F_L_A_G_S environment variable and will
+ be processed by any child make processes. By default, debugging
+ information is printed to standard error, but this can be changed
+ using the _F debugging flag. The debugging output is always
+ unbuffered; in addition, if debugging is enabled but debugging
+ output is not directed to standard output, then the standard out-
+ put is line buffered. _F_l_a_g_s is one or more of the following:
+
+ _A Print all possible debugging information; equivalent to
+ specifying all of the debugging flags.
+
+ _a Print debugging information about archive searching and
+ caching.
+
+ _C Print debugging information about current working direc-
+ tory.
+
+ _c Print debugging information about conditional evaluation.
+
+ _d Print debugging information about directory searching and
+ caching.
+
+ _e Print debugging information about failed commands and
+ targets.
+
+ _F[++]_f_i_l_e_n_a_m_e
+ Specify where debugging output is written. This must be
+ the last flag, because it consumes the remainder of the
+ argument. If the character immediately after the `F'
+ flag is `+', then the file will be opened in append mode;
+ otherwise the file will be overwritten. If the file name
+ is `stdout' or `stderr' then debugging output will be
+ written to the standard output or standard error output
+ file descriptors respectively (and the `+' option has no
+ effect). Otherwise, the output will be written to the
+ named file. If the file name ends `.%d' then the `%d' is
+ replaced by the pid.
+
+ _f Print debugging information about loop evaluation.
+
+ _g_1 Print the input graph before making anything.
+
+ _g_2 Print the input graph after making everything, or before
+ exiting on error.
+
+ _g_3 Print the input graph before exiting on error.
+
+ _j Print debugging information about running multiple
+ shells.
+
+ _l Print commands in Makefiles regardless of whether or not
+ they are prefixed by `@' or other "quiet" flags. Also
+ known as "loud" behavior.
+
+ _M Print debugging information about "meta" mode decisions
+ about targets.
+
+ _m Print debugging information about making targets, includ-
+ ing modification dates.
+
+ _n Don't delete the temporary command scripts created when
+ running commands. These temporary scripts are created in
+ the directory referred to by the TMPDIR environment vari-
+ able, or in _/_t_m_p if TMPDIR is unset or set to the empty
+ string. The temporary scripts are created by mkstemp(3),
+ and have names of the form _m_a_k_e_X_X_X_X_X_X. _N_O_T_E: This can
+ create many files in TMPDIR or _/_t_m_p, so use with care.
+
+ _p Print debugging information about makefile parsing.
+
+ _s Print debugging information about suffix-transformation
+ rules.
+
+ _t Print debugging information about target list mainte-
+ nance.
+
+ _V Force the --VV option to print raw values of variables,
+ overriding the default behavior set via
+ _._M_A_K_E_._E_X_P_A_N_D___V_A_R_I_A_B_L_E_S.
+
+ _v Print debugging information about variable assignment.
+
+ _x Run shell commands with --xx so the actual commands are
+ printed as they are executed.
+
+ --ee Specify that environment variables override macro assignments
+ within makefiles.
+
+ --ff _m_a_k_e_f_i_l_e
+ Specify a makefile to read instead of the default `_m_a_k_e_f_i_l_e'. If
+ _m_a_k_e_f_i_l_e is `--', standard input is read. Multiple makefiles may
+ be specified, and are read in the order specified.
+
+ --II _d_i_r_e_c_t_o_r_y
+ Specify a directory in which to search for makefiles and included
+ makefiles. The system makefile directory (or directories, see
+ the --mm option) is automatically included as part of this list.
+
+ --ii Ignore non-zero exit of shell commands in the makefile. Equiva-
+ lent to specifying `--' before each command line in the makefile.
+
+ --JJ _p_r_i_v_a_t_e
+ This option should _n_o_t be specified by the user.
+
+ When the _j option is in use in a recursive build, this option is
+ passed by a make to child makes to allow all the make processes
+ in the build to cooperate to avoid overloading the system.
+
+ --jj _m_a_x___j_o_b_s
+ Specify the maximum number of jobs that bbmmaakkee may have running at
+ any one time. The value is saved in _._M_A_K_E_._J_O_B_S. Turns compati-
+ bility mode off, unless the _B flag is also specified. When com-
+ patibility mode is off, all commands associated with a target are
+ executed in a single shell invocation as opposed to the tradi-
+ tional one shell invocation per line. This can break traditional
+ scripts which change directories on each command invocation and
+ then expect to start with a fresh environment on the next line.
+ It is more efficient to correct the scripts rather than turn
+ backwards compatibility on.
+
+ --kk Continue processing after errors are encountered, but only on
+ those targets that do not depend on the target whose creation
+ caused the error.
+
+ --mm _d_i_r_e_c_t_o_r_y
+ Specify a directory in which to search for sys.mk and makefiles
+ included via the <_f_i_l_e>-style include statement. The --mm option
+ can be used multiple times to form a search path. This path will
+ override the default system include path: /usr/share/mk. Fur-
+ thermore the system include path will be appended to the search
+ path used for "_f_i_l_e"-style include statements (see the --II
+ option).
+
+ If a file or directory name in the --mm argument (or the
+ MAKESYSPATH environment variable) starts with the string ".../"
+ then bbmmaakkee will search for the specified file or directory named
+ in the remaining part of the argument string. The search starts
+ with the current directory of the Makefile and then works upward
+ towards the root of the file system. If the search is success-
+ ful, then the resulting directory replaces the ".../" specifica-
+ tion in the --mm argument. If used, this feature allows bbmmaakkee to
+ easily search in the current source tree for customized sys.mk
+ files (e.g., by using ".../mk/sys.mk" as an argument).
+
+ --nn Display the commands that would have been executed, but do not
+ actually execute them unless the target depends on the .MAKE spe-
+ cial source (see below).
+
+ --NN Display the commands which would have been executed, but do not
+ actually execute any of them; useful for debugging top-level
+ makefiles without descending into subdirectories.
+
+ --qq Do not execute any commands, but exit 0 if the specified targets
+ are up-to-date and 1, otherwise.
+
+ --rr Do not use the built-in rules specified in the system makefile.
+
+ --ss Do not echo any commands as they are executed. Equivalent to
+ specifying `@@' before each command line in the makefile.
+
+ --TT _t_r_a_c_e_f_i_l_e
+ When used with the --jj flag, append a trace record to _t_r_a_c_e_f_i_l_e
+ for each job started and completed.
+
+ --tt Rather than re-building a target as specified in the makefile,
+ create it or update its modification time to make it appear up-
+ to-date.
+
+ --VV _v_a_r_i_a_b_l_e
+ Print the value of _v_a_r_i_a_b_l_e. Do not build any targets. Multiple
+ instances of this option may be specified; the variables will be
+ printed one per line, with a blank line for each null or unde-
+ fined variable. The value printed is extracted from the global
+ context after all makefiles have been read. By default, the raw
+ variable contents (which may include additional unexpanded vari-
+ able references) are shown. If _v_a_r_i_a_b_l_e contains a `$' then the
+ value will be recursively expanded to its complete resultant text
+ before printing. The expanded value will also be printed if
+ _._M_A_K_E_._E_X_P_A_N_D___V_A_R_I_A_B_L_E_S is set to true and the --ddVV option has not
+ been used to override it. Note that loop-local and target-local
+ variables, as well as values taken temporarily by global vari-
+ ables during makefile processing, are not accessible via this
+ option. The --ddvv debug mode can be used to see these at the cost
+ of generating substantial extraneous output.
+
+ --vv _v_a_r_i_a_b_l_e
+ Like --VV but the variable is always expanded to its complete
+ value.
+
+ --WW Treat any warnings during makefile parsing as errors.
+
+ --ww Print entering and leaving directory messages, pre and post pro-
+ cessing.
+
+ --XX Don't export variables passed on the command line to the environ-
+ ment individually. Variables passed on the command line are
+ still exported via the _M_A_K_E_F_L_A_G_S environment variable. This
+ option may be useful on systems which have a small limit on the
+ size of command arguments.
+
+ _v_a_r_i_a_b_l_e_=_v_a_l_u_e
+ Set the value of the variable _v_a_r_i_a_b_l_e to _v_a_l_u_e. Normally, all
+ values passed on the command line are also exported to sub-makes
+ in the environment. The --XX flag disables this behavior. Vari-
+ able assignments should follow options for POSIX compatibility
+ but no ordering is enforced.
+
+ There are seven different types of lines in a makefile: file dependency
+ specifications, shell commands, variable assignments, include statements,
+ conditional directives, for loops, and comments.
+
+ In general, lines may be continued from one line to the next by ending
+ them with a backslash (`\'). The trailing newline character and initial
+ whitespace on the following line are compressed into a single space.
+
+FFIILLEE DDEEPPEENNDDEENNCCYY SSPPEECCIIFFIICCAATTIIOONNSS
+ Dependency lines consist of one or more targets, an operator, and zero or
+ more sources. This creates a relationship where the targets ``depend''
+ on the sources and are usually created from them. The exact relationship
+ between the target and the source is determined by the operator that sep-
+ arates them. The three operators are as follows:
+
+ :: A target is considered out-of-date if its modification time is less
+ than those of any of its sources. Sources for a target accumulate
+ over dependency lines when this operator is used. The target is
+ removed if bbmmaakkee is interrupted.
+
+ !! Targets are always re-created, but not until all sources have been
+ examined and re-created as necessary. Sources for a target accumu-
+ late over dependency lines when this operator is used. The target
+ is removed if bbmmaakkee is interrupted.
+
+ :::: If no sources are specified, the target is always re-created. Oth-
+ erwise, a target is considered out-of-date if any of its sources
+ has been modified more recently than the target. Sources for a
+ target do not accumulate over dependency lines when this operator
+ is used. The target will not be removed if bbmmaakkee is interrupted.
+
+ Targets and sources may contain the shell wildcard values `?', `*', `[]',
+ and `{}'. The values `?', `*', and `[]' may only be used as part of the
+ final component of the target or source, and must be used to describe
+ existing files. The value `{}' need not necessarily be used to describe
+ existing files. Expansion is in directory order, not alphabetically as
+ done in the shell.
+
+SSHHEELLLL CCOOMMMMAANNDDSS
+ Each target may have associated with it one or more lines of shell com-
+ mands, normally used to create the target. Each of the lines in this
+ script _m_u_s_t be preceded by a tab. (For historical reasons, spaces are
+ not accepted.) While targets can appear in many dependency lines if
+ desired, by default only one of these rules may be followed by a creation
+ script. If the `::::' operator is used, however, all rules may include
+ scripts and the scripts are executed in the order found.
+
+ Each line is treated as a separate shell command, unless the end of line
+ is escaped with a backslash (`\') in which case that line and the next
+ are combined. If the first characters of the command are any combination
+ of `@@', `++', or `--', the command is treated specially. A `@@' causes the
+ command not to be echoed before it is executed. A `++' causes the command
+ to be executed even when --nn is given. This is similar to the effect of
+ the .MAKE special source, except that the effect can be limited to a sin-
+ gle line of a script. A `--' in compatibility mode causes any non-zero
+ exit status of the command line to be ignored.
+
+ When bbmmaakkee is run in jobs mode with --jj _m_a_x___j_o_b_s, the entire script for
+ the target is fed to a single instance of the shell. In compatibility
+ (non-jobs) mode, each command is run in a separate process. If the com-
+ mand contains any shell meta characters (`#=|^(){};&<>*?[]:$`\\n') it
+ will be passed to the shell; otherwise bbmmaakkee will attempt direct execu-
+ tion. If a line starts with `--' and the shell has ErrCtl enabled then
+ failure of the command line will be ignored as in compatibility mode.
+ Otherwise `--' affects the entire job; the script will stop at the first
+ command line that fails, but the target will not be deemed to have
+ failed.
+
+ Makefiles should be written so that the mode of bbmmaakkee operation does not
+ change their behavior. For example, any command which needs to use
+ ``cd'' or ``chdir'' without potentially changing the directory for subse-
+ quent commands should be put in parentheses so it executes in a subshell.
+ To force the use of one shell, escape the line breaks so as to make the
+ whole script one command. For example:
+
+ avoid-chdir-side-effects:
+ @echo Building $@ in `pwd`
+ @(cd ${.CURDIR} && ${MAKE} $@)
+ @echo Back in `pwd`
+
+ ensure-one-shell-regardless-of-mode:
+ @echo Building $@ in `pwd`; \
+ (cd ${.CURDIR} && ${MAKE} $@); \
+ echo Back in `pwd`
+
+ Since bbmmaakkee will chdir(2) to `_._O_B_J_D_I_R' before executing any targets, each
+ child process starts with that as its current working directory.
+
+VVAARRIIAABBLLEE AASSSSIIGGNNMMEENNTTSS
+ Variables in make are much like variables in the shell, and, by tradi-
+ tion, consist of all upper-case letters.
+
+ VVaarriiaabbllee aassssiiggnnmmeenntt mmooddiiffiieerrss
+ The five operators that can be used to assign values to variables are as
+ follows:
+
+ == Assign the value to the variable. Any previous value is overrid-
+ den.
+
+ ++== Append the value to the current value of the variable.
+
+ ??== Assign the value to the variable if it is not already defined.
+
+ ::== Assign with expansion, i.e. expand the value before assigning it
+ to the variable. Normally, expansion is not done until the vari-
+ able is referenced. _N_O_T_E: References to undefined variables are
+ _n_o_t expanded. This can cause problems when variable modifiers
+ are used.
+
+ !!== Expand the value and pass it to the shell for execution and
+ assign the result to the variable. Any newlines in the result
+ are replaced with spaces.
+
+ Any white-space before the assigned _v_a_l_u_e is removed; if the value is
+ being appended, a single space is inserted between the previous contents
+ of the variable and the appended value.
+
+ Variables are expanded by surrounding the variable name with either curly
+ braces (`{}') or parentheses (`()') and preceding it with a dollar sign
+ (`$'). If the variable name contains only a single letter, the surround-
+ ing braces or parentheses are not required. This shorter form is not
+ recommended.
+
+ If the variable name contains a dollar, then the name itself is expanded
+ first. This allows almost arbitrary variable names, however names con-
+ taining dollar, braces, parenthesis, or whitespace are really best
+ avoided!
+
+ If the result of expanding a variable contains a dollar sign (`$') the
+ string is expanded again.
+
+ Variable substitution occurs at three distinct times, depending on where
+ the variable is being used.
+
+ 1. Variables in dependency lines are expanded as the line is read.
+
+ 2. Variables in shell commands are expanded when the shell command is
+ executed.
+
+ 3. ``.for'' loop index variables are expanded on each loop iteration.
+ Note that other variables are not expanded inside loops so the fol-
+ lowing example code:
+
+
+ .for i in 1 2 3
+ a+= ${i}
+ j= ${i}
+ b+= ${j}
+ .endfor
+
+ all:
+ @echo ${a}
+ @echo ${b}
+
+ will print:
+
+ 1 2 3
+ 3 3 3
+
+ Because while ${a} contains ``1 2 3'' after the loop is executed,
+ ${b} contains ``${j} ${j} ${j}'' which expands to ``3 3 3'' since
+ after the loop completes ${j} contains ``3''.
+
+ VVaarriiaabbllee ccllaasssseess
+ The four different classes of variables (in order of increasing prece-
+ dence) are:
+
+ Environment variables
+ Variables defined as part of bbmmaakkee's environment.
+
+ Global variables
+ Variables defined in the makefile or in included makefiles.
+
+ Command line variables
+ Variables defined as part of the command line.
+
+ Local variables
+ Variables that are defined specific to a certain target.
+
+ Local variables are all built in and their values vary magically from
+ target to target. It is not currently possible to define new local vari-
+ ables. The seven local variables are as follows:
+
+ _._A_L_L_S_R_C The list of all sources for this target; also known as
+ `_>'.
+
+ _._A_R_C_H_I_V_E The name of the archive file; also known as `_!'.
+
+ _._I_M_P_S_R_C In suffix-transformation rules, the name/path of the
+ source from which the target is to be transformed (the
+ ``implied'' source); also known as `_<'. It is not
+ defined in explicit rules.
+
+ _._M_E_M_B_E_R The name of the archive member; also known as `_%'.
+
+ _._O_O_D_A_T_E The list of sources for this target that were deemed out-
+ of-date; also known as `_?'.
+
+ _._P_R_E_F_I_X The file prefix of the target, containing only the file
+ portion, no suffix or preceding directory components;
+ also known as `_*'. The suffix must be one of the known
+ suffixes declared with ..SSUUFFFFIIXXEESS or it will not be recog-
+ nized.
+
+ _._T_A_R_G_E_T The name of the target; also known as `_@'. For compati-
+ bility with other makes this is an alias for ..AARRCCHHIIVVEE in
+ archive member rules.
+
+ The shorter forms (`_>', `_!', `_<', `_%', `_?', `_*', and `_@') are permitted
+ for backward compatibility with historical makefiles and legacy POSIX
+ make and are not recommended.
+
+ Variants of these variables with the punctuation followed immediately by
+ `D' or `F', e.g. `_$_(_@_D_)', are legacy forms equivalent to using the `:H'
+ and `:T' modifiers. These forms are accepted for compatibility with AT&T
+ System V UNIX makefiles and POSIX but are not recommended.
+
+ Four of the local variables may be used in sources on dependency lines
+ because they expand to the proper value for each target on the line.
+ These variables are `_._T_A_R_G_E_T', `_._P_R_E_F_I_X', `_._A_R_C_H_I_V_E', and `_._M_E_M_B_E_R'.
+
+ AAddddiittiioonnaall bbuuiilltt--iinn vvaarriiaabblleess
+ In addition, bbmmaakkee sets or knows about the following variables:
+
+ _$ A single dollar sign `$', i.e. `$$' expands to a single
+ dollar sign.
+
+ _._A_L_L_T_A_R_G_E_T_S The list of all targets encountered in the Makefile. If
+ evaluated during Makefile parsing, lists only those tar-
+ gets encountered thus far.
+
+ _._C_U_R_D_I_R A path to the directory where bbmmaakkee was executed. Refer
+ to the description of `PWD' for more details.
+
+ _._I_N_C_L_U_D_E_D_F_R_O_M_D_I_R
+ The directory of the file this Makefile was included
+ from.
+
+ _._I_N_C_L_U_D_E_D_F_R_O_M_F_I_L_E
+ The filename of the file this Makefile was included from.
+
+ MAKE The name that bbmmaakkee was executed with (_a_r_g_v_[_0_]). For
+ compatibility bbmmaakkee also sets _._M_A_K_E with the same value.
+ The preferred variable to use is the environment variable
+ MAKE because it is more compatible with other versions of
+ bbmmaakkee and cannot be confused with the special target with
+ the same name.
+
+ _._M_A_K_E_._D_E_P_E_N_D_F_I_L_E
+ Names the makefile (default `_._d_e_p_e_n_d') from which gener-
+ ated dependencies are read.
+
+ _._M_A_K_E_._E_X_P_A_N_D___V_A_R_I_A_B_L_E_S
+ A boolean that controls the default behavior of the --VV
+ option. If true, variable values printed with --VV are
+ fully expanded; if false, the raw variable contents
+ (which may include additional unexpanded variable refer-
+ ences) are shown.
+
+ _._M_A_K_E_._E_X_P_O_R_T_E_D The list of variables exported by bbmmaakkee.
+
+ _._M_A_K_E_._J_O_B_S The argument to the --jj option.
+
+ _._M_A_K_E_._J_O_B_._P_R_E_F_I_X
+ If bbmmaakkee is run with _j then output for each target is
+ prefixed with a token `--- target ---' the first part of
+ which can be controlled via _._M_A_K_E_._J_O_B_._P_R_E_F_I_X. If
+ _._M_A_K_E_._J_O_B_._P_R_E_F_I_X is empty, no token is printed.
+ For example:
+ .MAKE.JOB.PREFIX=${.newline}---${.MAKE:T}[${.MAKE.PID}]
+ would produce tokens like `---make[1234] target ---' mak-
+ ing it easier to track the degree of parallelism being
+ achieved.
+
+ MAKEFLAGS The environment variable `MAKEFLAGS' may contain anything
+ that may be specified on bbmmaakkee's command line. Anything
+ specified on bbmmaakkee's command line is appended to the
+ `MAKEFLAGS' variable which is then entered into the envi-
+ ronment for all programs which bbmmaakkee executes.
+
+ _._M_A_K_E_._L_E_V_E_L The recursion depth of bbmmaakkee. The initial instance of
+ bbmmaakkee will be 0, and an incremented value is put into the
+ environment to be seen by the next generation. This
+ allows tests like: .if ${.MAKE.LEVEL} == 0 to protect
+ things which should only be evaluated in the initial
+ instance of bbmmaakkee.
+
+ _._M_A_K_E_._M_A_K_E_F_I_L_E___P_R_E_F_E_R_E_N_C_E
+ The ordered list of makefile names (default `_m_a_k_e_f_i_l_e',
+ `_M_a_k_e_f_i_l_e') that bbmmaakkee will look for.
+
+ _._M_A_K_E_._M_A_K_E_F_I_L_E_S
+ The list of makefiles read by bbmmaakkee, which is useful for
+ tracking dependencies. Each makefile is recorded only
+ once, regardless of the number of times read.
+
+ _._M_A_K_E_._M_O_D_E Processed after reading all makefiles. Can affect the
+ mode that bbmmaakkee runs in. It can contain a number of key-
+ words:
+
+ _c_o_m_p_a_t Like --BB, puts bbmmaakkee into "compat"
+ mode.
+
+ _m_e_t_a Puts bbmmaakkee into "meta" mode, where
+ meta files are created for each tar-
+ get to capture the command run, the
+ output generated and if filemon(4)
+ is available, the system calls which
+ are of interest to bbmmaakkee. The cap-
+ tured output can be very useful when
+ diagnosing errors.
+
+ _c_u_r_d_i_r_O_k_= _b_f Normally bbmmaakkee will not create .meta
+ files in `_._C_U_R_D_I_R'. This can be
+ overridden by setting _b_f to a value
+ which represents True.
+
+ _m_i_s_s_i_n_g_-_m_e_t_a_= _b_f If _b_f is True, then a missing .meta
+ file makes the target out-of-date.
+
+ _m_i_s_s_i_n_g_-_f_i_l_e_m_o_n_= _b_f If _b_f is True, then missing filemon
+ data makes the target out-of-date.
+
+ _n_o_f_i_l_e_m_o_n Do not use filemon(4).
+
+ _e_n_v For debugging, it can be useful to
+ include the environment in the .meta
+ file.
+
+ _v_e_r_b_o_s_e If in "meta" mode, print a clue
+ about the target being built. This
+ is useful if the build is otherwise
+ running silently. The message
+ printed the value of:
+ _._M_A_K_E_._M_E_T_A_._P_R_E_F_I_X.
+
+ _i_g_n_o_r_e_-_c_m_d Some makefiles have commands which
+ are simply not stable. This keyword
+ causes them to be ignored for deter-
+ mining whether a target is out of
+ date in "meta" mode. See also
+ ..NNOOMMEETTAA__CCMMPP.
+
+ _s_i_l_e_n_t_= _b_f If _b_f is True, when a .meta file is
+ created, mark the target ..SSIILLEENNTT.
+
+ _._M_A_K_E_._M_E_T_A_._B_A_I_L_I_W_I_C_K
+ In "meta" mode, provides a list of prefixes which match
+ the directories controlled by bbmmaakkee. If a file that was
+ generated outside of _._O_B_J_D_I_R but within said bailiwick is
+ missing, the current target is considered out-of-date.
+
+ _._M_A_K_E_._M_E_T_A_._C_R_E_A_T_E_D
+ In "meta" mode, this variable contains a list of all the
+ meta files updated. If not empty, it can be used to
+ trigger processing of _._M_A_K_E_._M_E_T_A_._F_I_L_E_S.
+
+ _._M_A_K_E_._M_E_T_A_._F_I_L_E_S
+ In "meta" mode, this variable contains a list of all the
+ meta files used (updated or not). This list can be used
+ to process the meta files to extract dependency informa-
+ tion.
+
+ _._M_A_K_E_._M_E_T_A_._I_G_N_O_R_E___P_A_T_H_S
+ Provides a list of path prefixes that should be ignored;
+ because the contents are expected to change over time.
+ The default list includes: `_/_d_e_v _/_e_t_c _/_p_r_o_c _/_t_m_p _/_v_a_r_/_r_u_n
+ _/_v_a_r_/_t_m_p'
+
+ _._M_A_K_E_._M_E_T_A_._I_G_N_O_R_E___P_A_T_T_E_R_N_S
+ Provides a list of patterns to match against pathnames.
+ Ignore any that match.
+
+ _._M_A_K_E_._M_E_T_A_._I_G_N_O_R_E___F_I_L_T_E_R
+ Provides a list of variable modifiers to apply to each
+ pathname. Ignore if the expansion is an empty string.
+
+ _._M_A_K_E_._M_E_T_A_._P_R_E_F_I_X
+ Defines the message printed for each meta file updated in
+ "meta verbose" mode. The default value is:
+ Building ${.TARGET:H:tA}/${.TARGET:T}
+
+ _._M_A_K_E_O_V_E_R_R_I_D_E_S This variable is used to record the names of variables
+ assigned to on the command line, so that they may be
+ exported as part of `MAKEFLAGS'. This behavior can be
+ disabled by assigning an empty value to `_._M_A_K_E_O_V_E_R_R_I_D_E_S'
+ within a makefile. Extra variables can be exported from
+ a makefile by appending their names to `_._M_A_K_E_O_V_E_R_R_I_D_E_S'.
+ `MAKEFLAGS' is re-exported whenever `_._M_A_K_E_O_V_E_R_R_I_D_E_S' is
+ modified.
+
+ _._M_A_K_E_._P_A_T_H___F_I_L_E_M_O_N
+ If bbmmaakkee was built with filemon(4) support, this is set
+ to the path of the device node. This allows makefiles to
+ test for this support.
+
+ _._M_A_K_E_._P_I_D The process-id of bbmmaakkee.
+
+ _._M_A_K_E_._P_P_I_D The parent process-id of bbmmaakkee.
+
+ _._M_A_K_E_._S_A_V_E___D_O_L_L_A_R_S
+ value should be a boolean that controls whether `$$' are
+ preserved when doing `:=' assignments. The default is
+ false, for backwards compatibility. Set to true for com-
+ patability with other makes. If set to false, `$$'
+ becomes `$' per normal evaluation rules.
+
+ _M_A_K_E___P_R_I_N_T___V_A_R___O_N___E_R_R_O_R
+ When bbmmaakkee stops due to an error, it sets `_._E_R_R_O_R___T_A_R_G_E_T'
+ to the name of the target that failed, `_._E_R_R_O_R___C_M_D' to
+ the commands of the failed target, and in "meta" mode, it
+ also sets `_._E_R_R_O_R___C_W_D' to the getcwd(3), and
+ `_._E_R_R_O_R___M_E_T_A___F_I_L_E' to the path of the meta file (if any)
+ describing the failed target. It then prints its name
+ and the value of `_._C_U_R_D_I_R' as well as the value of any
+ variables named in `_M_A_K_E___P_R_I_N_T___V_A_R___O_N___E_R_R_O_R'.
+
+ _._n_e_w_l_i_n_e This variable is simply assigned a newline character as
+ its value. This allows expansions using the ::@@ modifier
+ to put a newline between iterations of the loop rather
+ than a space. For example, the printing of
+ `_M_A_K_E___P_R_I_N_T___V_A_R___O_N___E_R_R_O_R' could be done as
+ ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@}.
+
+ _._O_B_J_D_I_R A path to the directory where the targets are built. Its
+ value is determined by trying to chdir(2) to the follow-
+ ing directories in order and using the first match:
+
+ 1. ${MAKEOBJDIRPREFIX}${.CURDIR}
+
+ (Only if `MAKEOBJDIRPREFIX' is set in the environ-
+ ment or on the command line.)
+
+ 2. ${MAKEOBJDIR}
+
+ (Only if `MAKEOBJDIR' is set in the environment or
+ on the command line.)
+
+ 3. ${.CURDIR}_/_o_b_j_.${MACHINE}
+
+ 4. ${.CURDIR}_/_o_b_j
+
+ 5. _/_u_s_r_/_o_b_j_/${.CURDIR}
+
+ 6. ${.CURDIR}
+
+ Variable expansion is performed on the value before it's
+ used, so expressions such as
+ ${.CURDIR:S,^/usr/src,/var/obj,}
+ may be used. This is especially useful with
+ `MAKEOBJDIR'.
+
+ `_._O_B_J_D_I_R' may be modified in the makefile via the special
+ target `..OOBBJJDDIIRR'. In all cases, bbmmaakkee will chdir(2) to
+ the specified directory if it exists, and set `_._O_B_J_D_I_R'
+ and `PWD' to that directory before executing any targets.
+
+ _._P_A_R_S_E_D_I_R A path to the directory of the current `_M_a_k_e_f_i_l_e' being
+ parsed.
+
+ _._P_A_R_S_E_F_I_L_E The basename of the current `_M_a_k_e_f_i_l_e' being parsed.
+ This variable and `_._P_A_R_S_E_D_I_R' are both set only while the
+ `_M_a_k_e_f_i_l_e_s' are being parsed. If you want to retain
+ their current values, assign them to a variable using
+ assignment with expansion: (`::==').
+
+ _._P_A_T_H A variable that represents the list of directories that
+ bbmmaakkee will search for files. The search list should be
+ updated using the target `_._P_A_T_H' rather than the vari-
+ able.
+
+ PWD Alternate path to the current directory. bbmmaakkee normally
+ sets `_._C_U_R_D_I_R' to the canonical path given by getcwd(3).
+ However, if the environment variable `PWD' is set and
+ gives a path to the current directory, then bbmmaakkee sets
+ `_._C_U_R_D_I_R' to the value of `PWD' instead. This behavior
+ is disabled if `MAKEOBJDIRPREFIX' is set or `MAKEOBJDIR'
+ contains a variable transform. `PWD' is set to the value
+ of `_._O_B_J_D_I_R' for all programs which bbmmaakkee executes.
+
+ .TARGETS The list of targets explicitly specified on the command
+ line, if any.
+
+ VPATH Colon-separated (``:'') lists of directories that bbmmaakkee
+ will search for files. The variable is supported for
+ compatibility with old make programs only, use `_._P_A_T_H'
+ instead.
+
+ VVaarriiaabbllee mmooddiiffiieerrss
+ Variable expansion may be modified to select or modify each word of the
+ variable (where a ``word'' is white-space delimited sequence of charac-
+ ters). The general format of a variable expansion is as follows:
+
+ ${variable[:modifier[:...]]}
+
+ Each modifier begins with a colon, which may be escaped with a backslash
+ (`\').
+
+ A set of modifiers can be specified via a variable, as follows:
+
+ modifier_variable=modifier[:...]
+ ${variable:${modifier_variable}[:...]}
+
+ In this case the first modifier in the modifier_variable does not start
+ with a colon, since that must appear in the referencing variable. If any
+ of the modifiers in the modifier_variable contain a dollar sign (`$'),
+ these must be doubled to avoid early expansion.
+
+ The supported modifiers are:
+
+ ::EE Replaces each word in the variable with its suffix.
+
+ ::HH Replaces each word in the variable with everything but the last com-
+ ponent.
+
+ ::MM_p_a_t_t_e_r_n
+ Select only those words that match _p_a_t_t_e_r_n. The standard shell
+ wildcard characters (`*', `?', and `[]') may be used. The wildcard
+ characters may be escaped with a backslash (`\'). As a consequence
+ of the way values are split into words, matched, and then joined, a
+ construct like
+ ${VAR:M*}
+ will normalize the inter-word spacing, removing all leading and
+ trailing space, and converting multiple consecutive spaces to single
+ spaces.
+
+ ::NN_p_a_t_t_e_r_n
+ This is identical to `::MM', but selects all words which do not match
+ _p_a_t_t_e_r_n.
+
+ ::OO Order every word in variable alphabetically. To sort words in
+ reverse order use the `::OO::[[--11....11]]' combination of modifiers.
+
+ ::OOxx Randomize words in variable. The results will be different each
+ time you are referring to the modified variable; use the assignment
+ with expansion (`::==') to prevent such behavior. For example,
+
+ LIST= uno due tre quattro
+ RANDOM_LIST= ${LIST:Ox}
+ STATIC_RANDOM_LIST:= ${LIST:Ox}
+
+ all:
+ @echo "${RANDOM_LIST}"
+ @echo "${RANDOM_LIST}"
+ @echo "${STATIC_RANDOM_LIST}"
+ @echo "${STATIC_RANDOM_LIST}"
+ may produce output similar to:
+
+ quattro due tre uno
+ tre due quattro uno
+ due uno quattro tre
+ due uno quattro tre
+
+ ::QQ Quotes every shell meta-character in the variable, so that it can be
+ passed safely through recursive invocations of bbmmaakkee.
+
+ ::RR Replaces each word in the variable with everything but its suffix.
+
+ ::rraannggee[[==ccoouunntt]]
+ The value is an integer sequence representing the words of the orig-
+ inal value, or the supplied _c_o_u_n_t.
+
+ ::ggmmttiimmee[[==uuttcc]]
+ The value is a format string for strftime(3), using gmtime(3). If a
+ _u_t_c value is not provided or is 0, the current time is used.
+
+ ::hhaasshh
+ Compute a 32-bit hash of the value and encode it as hex digits.
+
+ ::llooccaallttiimmee[[==uuttcc]]
+ The value is a format string for strftime(3), using localtime(3).
+ If a _u_t_c value is not provided or is 0, the current time is used.
+
+ ::ttAA Attempt to convert variable to an absolute path using realpath(3),
+ if that fails, the value is unchanged.
+
+ ::ttll Converts variable to lower-case letters.
+
+ ::ttss_c
+ Words in the variable are normally separated by a space on expan-
+ sion. This modifier sets the separator to the character _c. If _c is
+ omitted, then no separator is used. The common escapes (including
+ octal numeric codes), work as expected.
+
+ ::ttuu Converts variable to upper-case letters.
+
+ ::ttWW Causes the value to be treated as a single word (possibly containing
+ embedded white space). See also `::[[**]]'.
+
+ ::ttww Causes the value to be treated as a sequence of words delimited by
+ white space. See also `::[[@@]]'.
+
+ ::SS/_o_l_d___s_t_r_i_n_g/_n_e_w___s_t_r_i_n_g/[11ggWW]
+ Modify the first occurrence of _o_l_d___s_t_r_i_n_g in the variable's value,
+ replacing it with _n_e_w___s_t_r_i_n_g. If a `g' is appended to the last
+ slash of the pattern, all occurrences in each word are replaced. If
+ a `1' is appended to the last slash of the pattern, only the first
+ word is affected. If a `W' is appended to the last slash of the
+ pattern, then the value is treated as a single word (possibly con-
+ taining embedded white space). If _o_l_d___s_t_r_i_n_g begins with a caret
+ (`^'), _o_l_d___s_t_r_i_n_g is anchored at the beginning of each word. If
+ _o_l_d___s_t_r_i_n_g ends with a dollar sign (`$'), it is anchored at the end
+ of each word. Inside _n_e_w___s_t_r_i_n_g, an ampersand (`&') is replaced by
+ _o_l_d___s_t_r_i_n_g (without any `^' or `$'). Any character may be used as a
+ delimiter for the parts of the modifier string. The anchoring,
+ ampersand and delimiter characters may be escaped with a backslash
+ (`\').
+
+ Variable expansion occurs in the normal fashion inside both
+ _o_l_d___s_t_r_i_n_g and _n_e_w___s_t_r_i_n_g with the single exception that a backslash
+ is used to prevent the expansion of a dollar sign (`$'), not a pre-
+ ceding dollar sign as is usual.
+
+ ::CC/_p_a_t_t_e_r_n/_r_e_p_l_a_c_e_m_e_n_t/[11ggWW]
+ The ::CC modifier is just like the ::SS modifier except that the old and
+ new strings, instead of being simple strings, are an extended regu-
+ lar expression (see regex(3)) string _p_a_t_t_e_r_n and an ed(1)-style
+ string _r_e_p_l_a_c_e_m_e_n_t. Normally, the first occurrence of the pattern
+ _p_a_t_t_e_r_n in each word of the value is substituted with _r_e_p_l_a_c_e_m_e_n_t.
+ The `1' modifier causes the substitution to apply to at most one
+ word; the `g' modifier causes the substitution to apply to as many
+ instances of the search pattern _p_a_t_t_e_r_n as occur in the word or
+ words it is found in; the `W' modifier causes the value to be
+ treated as a single word (possibly containing embedded white space).
+ Note that `1' and `g' are orthogonal; the former specifies whether
+ multiple words are potentially affected, the latter whether multiple
+ substitutions can potentially occur within each affected word.
+
+ As for the ::SS modifier, the _p_a_t_t_e_r_n and _r_e_p_l_a_c_e_m_e_n_t are subjected to
+ variable expansion before being parsed as regular expressions.
+
+ ::TT Replaces each word in the variable with its last component.
+
+ ::uu Remove adjacent duplicate words (like uniq(1)).
+
+ ::??_t_r_u_e___s_t_r_i_n_g::_f_a_l_s_e___s_t_r_i_n_g
+ If the variable name (not its value), when parsed as a .if condi-
+ tional expression, evaluates to true, return as its value the
+ _t_r_u_e___s_t_r_i_n_g, otherwise return the _f_a_l_s_e___s_t_r_i_n_g. Since the variable
+ name is used as the expression, :? must be the first modifier after
+ the variable name itself - which will, of course, usually contain
+ variable expansions. A common error is trying to use expressions
+ like
+ ${NUMBERS:M42:?match:no}
+ which actually tests defined(NUMBERS), to determine is any words
+ match "42" you need to use something like:
+ ${"${NUMBERS:M42}" != "":?match:no}.
+
+ _:_o_l_d___s_t_r_i_n_g_=_n_e_w___s_t_r_i_n_g
+ This is the AT&T System V UNIX style variable substitution. It must
+ be the last modifier specified. If _o_l_d___s_t_r_i_n_g or _n_e_w___s_t_r_i_n_g do not
+ contain the pattern matching character _% then it is assumed that
+ they are anchored at the end of each word, so only suffixes or
+ entire words may be replaced. Otherwise _% is the substring of
+ _o_l_d___s_t_r_i_n_g to be replaced in _n_e_w___s_t_r_i_n_g.
+
+ Variable expansion occurs in the normal fashion inside both
+ _o_l_d___s_t_r_i_n_g and _n_e_w___s_t_r_i_n_g with the single exception that a backslash
+ is used to prevent the expansion of a dollar sign (`$'), not a pre-
+ ceding dollar sign as is usual.
+
+ ::@@_t_e_m_p@@_s_t_r_i_n_g@@
+ This is the loop expansion mechanism from the OSF Development Envi-
+ ronment (ODE) make. Unlike ..ffoorr loops expansion occurs at the time
+ of reference. Assign _t_e_m_p to each word in the variable and evaluate
+ _s_t_r_i_n_g. The ODE convention is that _t_e_m_p should start and end with a
+ period. For example.
+ ${LINKS:@.LINK.@${LN} ${TARGET} ${.LINK.}@}
+
+ However a single character variable is often more readable:
+ ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@}
+
+ ::__[[==vvaarr]]
+ Save the current variable value in `$_' or the named _v_a_r for later
+ reference. Example usage:
+
+ M_cmpv.units = 1 1000 1000000
+ M_cmpv = S,., ,g:_:range:@i at + $${_:[-$$i]} \
+ \* $${M_cmpv.units:[$$i]}@:S,^,expr 0 ,1:sh
+
+ .if ${VERSION:${M_cmpv}} < ${3.1.12:L:${M_cmpv}}
+
+ Here `$_' is used to save the result of the `:S' modifier which is
+ later referenced using the index values from `:range'.
+
+ ::UU_n_e_w_v_a_l
+ If the variable is undefined _n_e_w_v_a_l is the value. If the variable
+ is defined, the existing value is returned. This is another ODE
+ make feature. It is handy for setting per-target CFLAGS for
+ instance:
+ ${_${.TARGET:T}_CFLAGS:U${DEF_CFLAGS}}
+ If a value is only required if the variable is undefined, use:
+ ${VAR:D:Unewval}
+
+ ::DD_n_e_w_v_a_l
+ If the variable is defined _n_e_w_v_a_l is the value.
+
+ ::LL The name of the variable is the value.
+
+ ::PP The path of the node which has the same name as the variable is the
+ value. If no such node exists or its path is null, then the name of
+ the variable is used. In order for this modifier to work, the name
+ (node) must at least have appeared on the rhs of a dependency.
+
+ ::!!_c_m_d!!
+ The output of running _c_m_d is the value.
+
+ ::sshh If the variable is non-empty it is run as a command and the output
+ becomes the new value.
+
+ ::::==_s_t_r
+ The variable is assigned the value _s_t_r after substitution. This
+ modifier and its variations are useful in obscure situations such as
+ wanting to set a variable when shell commands are being parsed.
+ These assignment modifiers always expand to nothing, so if appearing
+ in a rule line by themselves should be preceded with something to
+ keep bbmmaakkee happy.
+
+ The `::::' helps avoid false matches with the AT&T System V UNIX style
+ ::== modifier and since substitution always occurs the ::::== form is
+ vaguely appropriate.
+
+ ::::??==_s_t_r
+ As for ::::== but only if the variable does not already have a value.
+
+ ::::++==_s_t_r
+ Append _s_t_r to the variable.
+
+ ::::!!==_c_m_d
+ Assign the output of _c_m_d to the variable.
+
+ ::[[_r_a_n_g_e]]
+ Selects one or more words from the value, or performs other opera-
+ tions related to the way in which the value is divided into words.
+
+ Ordinarily, a value is treated as a sequence of words delimited by
+ white space. Some modifiers suppress this behavior, causing a value
+ to be treated as a single word (possibly containing embedded white
+ space). An empty value, or a value that consists entirely of white-
+ space, is treated as a single word. For the purposes of the `::[[]]'
+ modifier, the words are indexed both forwards using positive inte-
+ gers (where index 1 represents the first word), and backwards using
+ negative integers (where index -1 represents the last word).
+
+ The _r_a_n_g_e is subjected to variable expansion, and the expanded
+ result is then interpreted as follows:
+
+ _i_n_d_e_x Selects a single word from the value.
+
+ _s_t_a_r_t...._e_n_d
+ Selects all words from _s_t_a_r_t to _e_n_d, inclusive. For example,
+ `::[[22....--11]]' selects all words from the second word to the last
+ word. If _s_t_a_r_t is greater than _e_n_d, then the words are out-
+ put in reverse order. For example, `::[[--11....11]]' selects all
+ the words from last to first.
+
+ ** Causes subsequent modifiers to treat the value as a single
+ word (possibly containing embedded white space). Analogous
+ to the effect of "$*" in Bourne shell.
+
+ 0 Means the same as `::[[**]]'.
+
+ @@ Causes subsequent modifiers to treat the value as a sequence

+ Makefile inclusion, conditional structures and for loops reminiscent of
+ the C programming language are provided in bbmmaakkee. All such structures
+ are identified by a line beginning with a single dot (`.') character.
+ Files are included with either ..iinncclluuddee <_f_i_l_e> or ..iinncclluuddee "_f_i_l_e". Vari-
+ ables between the angle brackets or double quotes are expanded to form
+ the file name. If angle brackets are used, the included makefile is
+ expected to be in the system makefile directory. If double quotes are
+ used, the including makefile's directory and any directories specified
+ using the --II option are searched before the system makefile directory.
+ For compatibility with other versions of bbmmaakkee `include file ...' is also
+ accepted.
+
+ If the include statement is written as ..--iinncclluuddee or as ..ssiinncclluuddee then
+ errors locating and/or opening include files are ignored.
+
+ If the include statement is written as ..ddiinncclluuddee not only are errors
+ locating and/or opening include files ignored, but stale dependencies
+ within the included file will be ignored just like _._M_A_K_E_._D_E_P_E_N_D_F_I_L_E.
+
+ Conditional expressions are also preceded by a single dot as the first
+ character of a line. The possible conditionals are as follows:
+
+ ..eerrrroorr _m_e_s_s_a_g_e
+ The message is printed along with the name of the makefile and
+ line number, then bbmmaakkee will exit.
+
+ ..eexxppoorrtt _v_a_r_i_a_b_l_e _._._.
+ Export the specified global variable. If no variable list is
+ provided, all globals are exported except for internal variables
+ (those that start with `.'). This is not affected by the --XX
+ flag, so should be used with caution. For compatibility with
+ other bbmmaakkee programs `export variable=value' is also accepted.
+
+ Appending a variable name to _._M_A_K_E_._E_X_P_O_R_T_E_D is equivalent to
+ exporting a variable.
+
+ ..eexxppoorrtt--eennvv _v_a_r_i_a_b_l_e _._._.
+ The same as `.export', except that the variable is not appended
+ to _._M_A_K_E_._E_X_P_O_R_T_E_D. This allows exporting a value to the environ-
+ ment which is different from that used by bbmmaakkee internally.
+
+ ..eexxppoorrtt--lliitteerraall _v_a_r_i_a_b_l_e _._._.
+ The same as `.export-env', except that variables in the value are
+ not expanded.
+
+ ..iinnffoo _m_e_s_s_a_g_e
+ The message is printed along with the name of the makefile and
+ line number.
+
+ ..uunnddeeff _v_a_r_i_a_b_l_e
+ Un-define the specified global variable. Only global variables
+ may be un-defined.
+
+ ..uunneexxppoorrtt _v_a_r_i_a_b_l_e _._._.
+ The opposite of `.export'. The specified global _v_a_r_i_a_b_l_e will be
+ removed from _._M_A_K_E_._E_X_P_O_R_T_E_D. If no variable list is provided,
+ all globals are unexported, and _._M_A_K_E_._E_X_P_O_R_T_E_D deleted.
+
+ ..uunneexxppoorrtt--eennvv
+ Unexport all globals previously exported and clear the environ-
+ ment inherited from the parent. This operation will cause a mem-
+ ory leak of the original environment, so should be used spar-
+ ingly. Testing for _._M_A_K_E_._L_E_V_E_L being 0, would make sense. Also
+ note that any variables which originated in the parent environ-
+ ment should be explicitly preserved if desired. For example:
+
+ .if ${.MAKE.LEVEL} == 0
+ PATH := ${PATH}
+ .unexport-env
+ .export PATH
+ .endif
+
+ Would result in an environment containing only `PATH', which is
+ the minimal useful environment. Actually `.MAKE.LEVEL' will also
+ be pushed into the new environment.
+
+ ..wwaarrnniinngg _m_e_s_s_a_g_e
+ The message prefixed by `_w_a_r_n_i_n_g_:' is printed along with the name
+ of the makefile and line number.
+
+ ..iiff [!]_e_x_p_r_e_s_s_i_o_n [_o_p_e_r_a_t_o_r _e_x_p_r_e_s_s_i_o_n _._._.]

+
+ ..eelliiffnnmmaakkee [!]_t_a_r_g_e_t [_o_p_e_r_a_t_o_r _t_a_r_g_e_t _._._.]
+ A combination of `..eellssee' followed by `..iiffnnmmaakkee'.
+
+ ..eennddiiff End the body of the conditional.
+
+ The _o_p_e_r_a_t_o_r may be any one of the following:
+
+ |||| Logical OR.
+
+ &&&& Logical AND; of higher precedence than ``||''.
+
+ As in C, bbmmaakkee will only evaluate a conditional as far as is necessary to
+ determine its value. Parentheses may be used to change the order of
+ evaluation. The boolean operator `!!' may be used to logically negate an
+ entire conditional. It is of higher precedence than `&&&&'.
+
+ The value of _e_x_p_r_e_s_s_i_o_n may be any of the following:
+
+ ddeeffiinneedd Takes a variable name as an argument and evaluates to true if
+ the variable has been defined.
+
+ mmaakkee Takes a target name as an argument and evaluates to true if the
+ target was specified as part of bbmmaakkee's command line or was
+ declared the default target (either implicitly or explicitly,
+ see _._M_A_I_N) before the line containing the conditional.
+
+ eemmppttyy Takes a variable, with possible modifiers, and evaluates to true
+ if the expansion of the variable would result in an empty
+ string.
+
+ eexxiissttss Takes a file name as an argument and evaluates to true if the
+ file exists. The file is searched for on the system search path
+ (see _._P_A_T_H).
+
+ ttaarrggeett Takes a target name as an argument and evaluates to true if the
+ target has been defined.
+
+ ccoommmmaannddss
+ Takes a target name as an argument and evaluates to true if the
+ target has been defined and has commands associated with it.
+
+ _E_x_p_r_e_s_s_i_o_n may also be an arithmetic or string comparison. Variable
+ expansion is performed on both sides of the comparison, after which the
+ integral values are compared. A value is interpreted as hexadecimal if
+ it is preceded by 0x, otherwise it is decimal; octal numbers are not sup-
+ ported. The standard C relational operators are all supported. If after
+ variable expansion, either the left or right hand side of a `====' or `!!=='
+ operator is not an integral value, then string comparison is performed
+ between the expanded variables. If no relational operator is given, it
+ is assumed that the expanded variable is being compared against 0 or an
+ empty string in the case of a string comparison.
+
+ When bbmmaakkee is evaluating one of these conditional expressions, and it
+ encounters a (white-space separated) word it doesn't recognize, either
+ the ``make'' or ``defined'' expression is applied to it, depending on the
+ form of the conditional. If the form is `..iiffddeeff', `..iiffnnddeeff', or `..iiff'
+ the ``defined'' expression is applied. Similarly, if the form is
+ `..iiffmmaakkee' or `..iiffnnmmaakkee, tthhee' ``make'' expression is applied.
+
+ If the conditional evaluates to true the parsing of the makefile contin-
+ ues as before. If it evaluates to false, the following lines are
+ skipped. In both cases this continues until a `..eellssee' or `..eennddiiff' is
+ found.
+
+ For loops are typically used to apply a set of rules to a list of files.
+ The syntax of a for loop is:
+
+ ..ffoorr _v_a_r_i_a_b_l_e [_v_a_r_i_a_b_l_e _._._.] iinn _e_x_p_r_e_s_s_i_o_n
+ <make-rules>
+ ..eennddffoorr
+
+ After the for eexxpprreessssiioonn is evaluated, it is split into words. On each
+ iteration of the loop, one word is taken and assigned to each vvaarriiaabbllee,
+ in order, and these vvaarriiaabblleess are substituted into the mmaakkee--rruulleess inside
+ the body of the for loop. The number of words must come out even; that
+ is, if there are three iteration variables, the number of words provided
+ must be a multiple of three.
+
+CCOOMMMMEENNTTSS
+ Comments begin with a hash (`#') character, anywhere but in a shell com-
+ mand line, and continue to the end of an unescaped new line.
+
+SSPPEECCIIAALL SSOOUURRCCEESS ((AATTTTRRIIBBUUTTEESS))
+ ..EEXXEECC Target is never out of date, but always execute commands any-
+ way.
+
+ ..IIGGNNOORREE Ignore any errors from the commands associated with this tar-
+ get, exactly as if they all were preceded by a dash (`-').
+
+ ..MMAADDEE Mark all sources of this target as being up-to-date.
+
+ ..MMAAKKEE Execute the commands associated with this target even if the --nn
+ or --tt options were specified. Normally used to mark recursive
+ bbmmaakkees.
+
+ ..MMEETTAA Create a meta file for the target, even if it is flagged as
+ ..PPHHOONNYY, ..MMAAKKEE, or ..SSPPEECCIIAALL. Usage in conjunction with ..MMAAKKEE is
+ the most likely case. In "meta" mode, the target is out-of-
+ date if the meta file is missing.
+
+ ..NNOOMMEETTAA Do not create a meta file for the target. Meta files are also
+ not created for ..PPHHOONNYY, ..MMAAKKEE, or ..SSPPEECCIIAALL targets.
+
+ ..NNOOMMEETTAA__CCMMPP
+ Ignore differences in commands when deciding if target is out
+ of date. This is useful if the command contains a value which
+ always changes. If the number of commands change, though, the
+ target will still be out of date. The same effect applies to
+ any command line that uses the variable _._O_O_D_A_T_E, which can be
+ used for that purpose even when not otherwise needed or
+ desired:
+
+
+ skip-compare-for-some:
+ @echo this will be compared
+ @echo this will not ${.OODATE:M.NOMETA_CMP}
+ @echo this will also be compared
+
+ The ::MM pattern suppresses any expansion of the unwanted vari-
+ able.
+
+ ..NNOOPPAATTHH Do not search for the target in the directories specified by
+ ..PPAATTHH.
+
+ ..NNOOTTMMAAIINN Normally bbmmaakkee selects the first target it encounters as the
+ default target to be built if no target was specified. This
+ source prevents this target from being selected.
+
+ ..OOPPTTIIOONNAALL
+ If a target is marked with this attribute and bbmmaakkee can't fig-
+ ure out how to create it, it will ignore this fact and assume
+ the file isn't needed or already exists.
+
+ ..PPHHOONNYY The target does not correspond to an actual file; it is always
+ considered to be out of date, and will not be created with the
+ --tt option. Suffix-transformation rules are not applied to
+ ..PPHHOONNYY targets.
+
+ ..PPRREECCIIOOUUSS
+ When bbmmaakkee is interrupted, it normally removes any partially
+ made targets. This source prevents the target from being
+ removed.
+
+ ..RREECCUURRSSIIVVEE
+ Synonym for ..MMAAKKEE.
+
+ ..SSIILLEENNTT Do not echo any of the commands associated with this target,
+ exactly as if they all were preceded by an at sign (`@').
+
+ ..UUSSEE Turn the target into bbmmaakkee's version of a macro. When the tar-
+ get is used as a source for another target, the other target
+ acquires the commands, sources, and attributes (except for
+ ..UUSSEE) of the source. If the target already has commands, the
+ ..UUSSEE target's commands are appended to them.
+
+ ..UUSSEEBBEEFFOORREE
+ Exactly like ..UUSSEE, but prepend the ..UUSSEEBBEEFFOORREE target commands
+ to the target.
+
+ ..WWAAIITT If ..WWAAIITT appears in a dependency line, the sources that precede
+ it are made before the sources that succeed it in the line.
+ Since the dependents of files are not made until the file
+ itself could be made, this also stops the dependents being
+ built unless they are needed for another branch of the depen-
+ dency tree. So given:
+
+ x: a .WAIT b
+ echo x
+ a:
+ echo a
+ b: b1
+ echo b
+ b1:
+ echo b1
+
+ the output is always `a', `b1', `b', `x'.
+ The ordering imposed by ..WWAAIITT is only relevant for parallel
+ makes.
+
+SSPPEECCIIAALL TTAARRGGEETTSS
+ Special targets may not be included with other targets, i.e. they must be
+ the only target specified.
+
+ ..BBEEGGIINN Any command lines attached to this target are executed before
+ anything else is done.
+
+ ..DDEEFFAAUULLTT
+ This is sort of a ..UUSSEE rule for any target (that was used only
+ as a source) that bbmmaakkee can't figure out any other way to cre-
+ ate. Only the shell script is used. The ..IIMMPPSSRRCC variable of a
+ target that inherits ..DDEEFFAAUULLTT's commands is set to the target's
+ own name.
+
+ ..DDEELLEETTEE__OONN__EERRRROORR
+ If this target is present in the makefile, it globally causes
+ make to delete targets whose commands fail. (By default, only
+ targets whose commands are interrupted during execution are
+ deleted. This is the historical behavior.) This setting can be
+ used to help prevent half-finished or malformed targets from
+ being left around and corrupting future rebuilds.
+
+ ..EENNDD Any command lines attached to this target are executed after
+ everything else is done.
+
+ ..EERRRROORR Any command lines attached to this target are executed when
+ another target fails. The ..EERRRROORR__TTAARRGGEETT variable is set to the
+ target that failed. See also MMAAKKEE__PPRRIINNTT__VVAARR__OONN__EERRRROORR.
+
+ ..IIGGNNOORREE Mark each of the sources with the ..IIGGNNOORREE attribute. If no
+ sources are specified, this is the equivalent of specifying the
+ --ii option.
+
+ ..IINNTTEERRRRUUPPTT
+ If bbmmaakkee is interrupted, the commands for this target will be
+ executed.
+
+ ..MMAAIINN If no target is specified when bbmmaakkee is invoked, this target
+ will be built.
+
+ ..MMAAKKEEFFLLAAGGSS
+ This target provides a way to specify flags for bbmmaakkee when the
+ makefile is used. The flags are as if typed to the shell,
+ though the --ff option will have no effect.
+
+ ..NNOOPPAATTHH Apply the ..NNOOPPAATTHH attribute to any specified sources.
+
+ ..NNOOTTPPAARRAALLLLEELL
+ Disable parallel mode.
+
+ ..NNOO__PPAARRAALLLLEELL
+ Synonym for ..NNOOTTPPAARRAALLLLEELL, for compatibility with other pmake
+ variants.
+
+ ..OOBBJJDDIIRR The source is a new value for `_._O_B_J_D_I_R'. If it exists, bbmmaakkee
+ will chdir(2) to it and update the value of `_._O_B_J_D_I_R'.
+
+ ..OORRDDEERR The named targets are made in sequence. This ordering does not
+ add targets to the list of targets to be made. Since the depen-
+ dents of a target do not get built until the target itself could
+ be built, unless `a' is built by another part of the dependency
+ graph, the following is a dependency loop:
+
+ .ORDER: b a
+ b: a
+
+ The ordering imposed by ..OORRDDEERR is only relevant for parallel
+ makes.
+
+ ..PPAATTHH The sources are directories which are to be searched for files
+ not found in the current directory. If no sources are speci-
+ fied, any previously specified directories are deleted. If the
+ source is the special ..DDOOTTLLAASSTT target, then the current working
+ directory is searched last.
+
+ ..PPAATTHH.._s_u_f_f_i_x
+ Like ..PPAATTHH but applies only to files with a particular suffix.
+ The suffix must have been previously declared with ..SSUUFFFFIIXXEESS.
+
+ ..PPHHOONNYY Apply the ..PPHHOONNYY attribute to any specified sources.
+
+ ..PPRREECCIIOOUUSS
+ Apply the ..PPRREECCIIOOUUSS attribute to any specified sources. If no
+ sources are specified, the ..PPRREECCIIOOUUSS attribute is applied to
+ every target in the file.
+
+ ..SSHHEELLLL Sets the shell that bbmmaakkee will use to execute commands. The
+ sources are a set of _f_i_e_l_d_=_v_a_l_u_e pairs.
+
+ _n_a_m_e This is the minimal specification, used to select
+ one of the built-in shell specs; _s_h, _k_s_h, and _c_s_h.
+
+ _p_a_t_h Specifies the path to the shell.
+
+ _h_a_s_E_r_r_C_t_l Indicates whether the shell supports exit on error.
+
+ _c_h_e_c_k The command to turn on error checking.
+
+ _i_g_n_o_r_e The command to disable error checking.
+
+ _e_c_h_o The command to turn on echoing of commands executed.
+
+ _q_u_i_e_t The command to turn off echoing of commands exe-
+ cuted.
+
+ _f_i_l_t_e_r The output to filter after issuing the _q_u_i_e_t com-
+ mand. It is typically identical to _q_u_i_e_t.
+
+ _e_r_r_F_l_a_g The flag to pass the shell to enable error checking.
+
+ _e_c_h_o_F_l_a_g The flag to pass the shell to enable command echo-
+ ing.
+
+ _n_e_w_l_i_n_e The string literal to pass the shell that results in
+ a single newline character when used outside of any
+ quoting characters.
+ Example:
+
+ .SHELL: name=ksh path=/bin/ksh hasErrCtl=true \
+ check="set -e" ignore="set +e" \
+ echo="set -v" quiet="set +v" filter="set +v" \
+ echoFlag=v errFlag=e newline="'\n'"
+
+ ..SSIILLEENNTT Apply the ..SSIILLEENNTT attribute to any specified sources. If no
+ sources are specified, the ..SSIILLEENNTT attribute is applied to every
+ command in the file.
+
+ ..SSTTAALLEE This target gets run when a dependency file contains stale
+ entries, having _._A_L_L_S_R_C set to the name of that dependency file.
+
+ ..SSUUFFFFIIXXEESS
+ Each source specifies a suffix to bbmmaakkee. If no sources are
+ specified, any previously specified suffixes are deleted. It
+ allows the creation of suffix-transformation rules.
+
+ Example:
+
+ .SUFFIXES: .o
+ .c.o:
+ cc -o ${.TARGET} -c ${.IMPSRC}
+
+EENNVVIIRROONNMMEENNTT
+ bbmmaakkee uses the following environment variables, if they exist: MACHINE,
+ MACHINE_ARCH, MAKE, MAKEFLAGS, MAKEOBJDIR, MAKEOBJDIRPREFIX, MAKESYSPATH,
+ PWD, and TMPDIR.
+
+ MAKEOBJDIRPREFIX and MAKEOBJDIR may only be set in the environment or on
+ the command line to bbmmaakkee and not as makefile variables; see the descrip-
+ tion of `_._O_B_J_D_I_R' for more details.

+CCOOMMPPAATTIIBBIILLIITTYY
+ The basic make syntax is compatible between different versions of make;
+ however the special variables, variable modifiers and conditionals are
+ not.
+
+ OOllddeerr vveerrssiioonnss
+ An incomplete list of changes in older versions of bbmmaakkee:
+
+ The way that .for loop variables are substituted changed after NetBSD 5.0
+ so that they still appear to be variable expansions. In particular this
+ stops them being treated as syntax, and removes some obscure problems
+ using them in .if statements.
+
+ The way that parallel makes are scheduled changed in NetBSD 4.0 so that
+ .ORDER and .WAIT apply recursively to the dependent nodes. The algo-
+ rithms used may change again in the future.
+
+ OOtthheerr mmaakkee ddiiaalleeccttss
+ Other make dialects (GNU make, SVR4 make, POSIX make, etc.) do not sup-
+ port most of the features of bbmmaakkee as described in this manual. Most
+ notably:
+
+ ++oo The ..WWAAIITT and ..OORRDDEERR declarations and most functionality per-
+ taining to parallelization. (GNU make supports parallelization
+ but lacks these features needed to control it effectively.)
+
+ ++oo Directives, including for loops and conditionals and most of
+ the forms of include files. (GNU make has its own incompatible
+ and less powerful syntax for conditionals.)
+
+ ++oo All built-in variables that begin with a dot.
+
+ ++oo Most of the special sources and targets that begin with a dot,
+ with the notable exception of ..PPHHOONNYY, ..PPRREECCIIOOUUSS, and ..SSUUFFFFIIXXEESS.
+
+ ++oo Variable modifiers, except for the
+ :old=new
+ string substitution, which does not portably support globbing
+ with `%' and historically only works on declared suffixes.
+
+ ++oo The $$>> variable even in its short form; most makes support this
+ functionality but its name varies.
+
+ Some features are somewhat more portable, such as assignment with ++==, ??==,
+ and !!==. The ..PPAATTHH functionality is based on an older feature VVPPAATTHH found
+ in GNU make and many versions of SVR4 make; however, historically its
+ behavior is too ill-defined (and too buggy) to rely upon.
+
+ The $$@@ and $$<< variables are more or less universally portable, as is the
+ $$((MMAAKKEE)) variable. Basic use of suffix rules (for files only in the cur-
+ rent directory, not trying to chain transformations together, etc.) is
+ also reasonably portable.
+
+SSEEEE AALLSSOO
+ mkdep(1)
+
+HHIISSTTOORRYY
+ bbmmaakkee is derived from NetBSD make(1). It uses autoconf to facilitate
+ portability to other platforms.
+
+ A make command appeared in Version 7 AT&T UNIX. This make implementation
+ is based on Adam De Boor's pmake program which was written for Sprite at
+ Berkeley. It was designed to be a parallel distributed make running jobs
+ on different machines using a daemon called ``customs''.
+
+ Historically the target/dependency ``FRC'' has been used to FoRCe
+ rebuilding (since the target/dependency does not exist... unless someone
+ creates an ``FRC'' file).
+
+BBUUGGSS
+ The make syntax is difficult to parse without actually acting of the
+ data. For instance finding the end of a variable use should involve
+ scanning each the modifiers using the correct terminator for each field.
+ In many places make just counts {} and () in order to find the end of a
+ variable expansion.
+
+ There is no way of escaping a space character in a filename.

-# NAME:
-# boot-strap
-#
-# SYNOPSIS:
-# boot-strap ["options"]
-# boot-strap --prefix=/opt --install
-# boot-strap --prefix=$HOME --install-host-target -DWITH_PROG_VERSION
-# boot-strap ["options"] op=build
-# boot-strap ["options"] op=install
-#
-# DESCRIPTION:
-# This script is used to configure/build bmake it builds for
-# each host-target in a different subdir to keep the src clean.
-# There is no requirement for an existing make(1).
-#
-# On successful completion if no '--install' flag is given,
-# it echos a command to do installation.
-#
-# The variable "op" defaults to 'all', and is affected by
-# '--install' flag as above.
-# Other values include:
-#
-# configure
-# Just run 'configure'
-#
-# build
-# If 'configure' has not been done, do it, then
-# run the build script, and finally 'test'.
-#
-# install
-# If 'build' has not been done, do it, 'test' then
-# install.
-#
-# clean
-# attempt to clean up
-#
-# test
-# run the unit-tests. Done automatically after 'build'
-# and before 'install'.
-#
-# The above are leveraged by a trivial makefile for the benefit
-# of those that have './configure; make; make install' baked
-# into them.
-#
-# Options:
-#
-# -c "rc"
-# Pick up settings from "rc".
-# We look for '.bmake-boot-strap.rc' before processing
-# options (unless SKIP_RC is set in environment).
-#
-# --share "share_dir"
-# Where to put man pages and mk files.
-# If $prefix ends in $HOST_TARGET, and $prefix/../share
-# exits, the default will be that rather than $prefix/share.
-#
-# --mksrc "mksrc"
-# Indicate where the mk files can be found.
-# Default is $Mydir/mk
-#
-# --install
-# If build and test work, run bmake install.
-# BINDIR=$prefix/bin
-# SHAREDIR=$prefix/share
-#
-# --install-host-target
-# As for '--install' but BINDIR=$prefix/$HOST_TARGET/bin
-# This is useful when $prefix/ is shared by multiple

-#
-# Flags relevant when installing:
-#
-# -DWITHOUT_INSTALL_MK
-# Skip installing mk files.
-# By default they will be installed to $prefix/share/mk
-#
-# -DWITH_PROG_VERSION
-# Install 'bmake' as 'bmake-$MAKE_VERSION'
-# A symlink will be made as 'bmake' unless
-# -DWITHOUT_PROG_LINK is set.
-#
-# Possibly useful configure_args:
-#
-# --without-meta
-# disable use of meta mode.
-#
-# --without-filemon
-# disable use of filemon(9) which is currently only
-# available for NetBSD and FreeBSD.
-#
-# --with-filemon="path/to/filemon.h"
-# enables use of filemon(9) by meta mode.
-#
-# --with-machine="machine"
-# set "machine" to override that determined by
-# machine.sh
-#
-# --with-force-machine="machine"
-# force "machine" even if uname(3) provides a value.
-#
-# --with-machine_arch="machine_arch"
-# set "machine_arch" to override that determined by
-# machine.sh
-#
-# --with-default-sys-path="syspath"
-# set an explicit default "syspath" which is where bmake
-# will look for sys.mk and friends.

+# NAME:
+# boot-strap
+#
+# SYNOPSIS:
+# boot-strap ["options"]
+# boot-strap --prefix=/opt --install
+# boot-strap --prefix=$HOME --install-host-target -DWITH_PROG_VERSION
+# boot-strap ["options"] op=build
+# boot-strap ["options"] op=install
+#
+# DESCRIPTION:
+# This script is used to configure/build bmake it builds for
+# each host-target in a different subdir to keep the src clean.
+# There is no requirement for an existing make(1).
+#
+# On successful completion if no '--install' flag is given,
+# it echos a command to do installation.
+#
+# The variable "op" defaults to 'all', and is affected by
+# '--install' flag as above.
+# Other values include:
+#
+# configure
+# Just run 'configure'
+#
+# build
+# If 'configure' has not been done, do it, then
+# run the build script, and finally 'test'.
+#
+# install
+# If 'build' has not been done, do it, 'test' then
+# install.
+#
+# clean
+# attempt to clean up
+#
+# test
+# run the unit-tests. Done automatically after 'build'
+# and before 'install'.
+#
+# The above are leveraged by a trivial makefile for the benefit
+# of those that have './configure; make; make install' baked
+# into them.
+#
+# Options:
+#
+# -c "rc"
+# Pick up settings from "rc".
+# We look for '.bmake-boot-strap.rc' before processing
+# options (unless SKIP_RC is set in environment).
+#
+# --share "share_dir"
+# Where to put man pages and mk files.
+# If $prefix ends in $HOST_TARGET, and $prefix/../share
+# exits, the default will be that rather than $prefix/share.
+#
+# --mksrc "mksrc"
+# Indicate where the mk files can be found.
+# Default is $Mydir/mk
+#
+# --install
+# If build and test work, run bmake install.
+# BINDIR=$prefix/bin
+# SHAREDIR=$prefix/share
+#
+# --install-host-target
+# As for '--install' but BINDIR=$prefix/$HOST_TARGET/bin
+# This is useful when $prefix/ is shared by multiple
+# machines.
+#
+# Flags relevant when installing:
+#
+# -DWITHOUT_INSTALL_MK
+# Skip installing mk files.
+# By default they will be installed to $prefix/share/mk
+#
+# -DWITH_PROG_VERSION
+# Install 'bmake' as 'bmake-$MAKE_VERSION'
+# A symlink will be made as 'bmake' unless
+# -DWITHOUT_PROG_LINK is set.
+#
+# Possibly useful configure_args:
+#
+# --without-meta
+# disable use of meta mode.
+#
+# --without-filemon
+# disable use of filemon(9) which is currently only
+# available for NetBSD and FreeBSD.
+#
+# --with-filemon="path/to/filemon.h"
+# enables use of filemon(9) by meta mode.
+#
+# --with-machine="machine"
+# set "machine" to override that determined by
+# machine.sh
+#
+# --with-force-machine="machine"
+# force "machine" even if uname(3) provides a value.
+#
+# --with-machine_arch="machine_arch"
+# set "machine_arch" to override that determined by
+# machine.sh
+#
+# --with-default-sys-path="syspath"
+# set an explicit default "syspath" which is where bmake
+# will look for sys.mk and friends.

-\`configure' configures bmake 20140214 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE. See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
- -h, --help display this help and exit
- --help=short display options specific to this package
- --help=recursive display the short help of all the included packages
- -V, --version display version information and exit
- -q, --quiet, --silent do not print \`checking...' messages
- --cache-file=FILE cache test results in FILE [disabled]
- -C, --config-cache alias for \`--cache-file=config.cache'
- -n, --no-create do not create output files
- --srcdir=DIR find the sources in DIR [configure dir or \`..']
-
-Installation directories:
- --prefix=PREFIX install architecture-independent files in PREFIX
- [$ac_default_prefix]
- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
- [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
- --bindir=DIR user executables [EPREFIX/bin]
- --sbindir=DIR system admin executables [EPREFIX/sbin]
- --libexecdir=DIR program executables [EPREFIX/libexec]
- --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
- --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
- --localstatedir=DIR modifiable single-machine data [PREFIX/var]
- --libdir=DIR object code libraries [EPREFIX/lib]
- --includedir=DIR C header files [PREFIX/include]
- --oldincludedir=DIR C header files for non-gcc [/usr/include]

-
-Optional Packages:
- --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
- --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
- --with-defshell=SHELL use SHELL by default - must be sh compatible, use sh or ksh to pick the internal definitions
- --without-meta dissable use of meta-mode
- --with-filemon=path/filemon.h indicate path to filemon.h for meta-mode
- --with-machine=MACHINE explicitly set MACHINE
- --with-force-machine=MACHINE set FORCE_MACHINE
- --with-force-machine-arch=MACHINE set FORCE_MACHINE_ARCH
- --with-machine_arch=MACHINE_ARCH explicitly set MACHINE_ARCH
- --with-default-sys-path=PATH:DIR:LIST use an explicit _PATH_DEFSYSPATH
- MAKESYSPATH is a ':' separated list of directories
- that bmake will search for system .mk files.
- _PATH_DEFSYSPATH is its default value.
- --with-path-objdirprefix=PATH override _PATH_OBJDIRPREFIX
- --with-mksrc=PATH tell makefile.boot where to find mk src
-
-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- LIBS libraries to pass to the linker, e.g. -l<library>
- CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
- you have headers in a nonstandard directory <include dir>
- CPP C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.

+\`configure' configures bmake 20160606 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
+ --localstatedir=DIR modifiable single-machine data [PREFIX/var]

+ MAKESYSPATH is a ':' separated list of directories
+ that bmake will search for system .mk files.
+ _PATH_DEFSYSPATH is its default value.
+ --with-path-objdirprefix=PATH override _PATH_OBJDIRPREFIX
+ --with-mksrc=PATH tell makefile.boot where to find mk src
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

-/*
- * A search path consists of a Lst of Path structures. A Path structure
- * has in it the name of the directory and a hash table of all the files
- * in the directory. This is used to cut down on the number of system
- * calls necessary to find implicit dependents and their like. Since
- * these searches are made before any actions are taken, we need not
- * worry about the directory changing due to creation commands. If this
- * hampers the style of some makefiles, they must be changed.
- *
- * A list of all previously-read directories is kept in the
- * openDirectories Lst. This list is checked first before a directory
- * is opened.
- *
- * The need for the caching of whole directories is brought about by
- * the multi-level transformation code in suff.c, which tends to search
- * for far more files than regular make does. In the initial
- * implementation, the amount of time spent performing "stat" calls was
- * truly astronomical. The problem with hashing at the start is,
- * of course, that pmake doesn't then detect changes to these directories
- * during the course of the make. Three possibilities suggest themselves:
- *
- * 1) just use stat to test for a file's existence. As mentioned
- * above, this is very inefficient due to the number of checks
- * engendered by the multi-level transformation code.
- * 2) use readdir() and company to search the directories, keeping
- * them open between checks. I have tried this and while it
- * didn't slow down the process too much, it could severely
- * affect the amount of parallelism available as each directory
- * open would take another file descriptor out of play for
- * handling I/O for another job. Given that it is only recently
- * that UNIX OS's have taken to allowing more than 20 or 32
- * file descriptors for a process, this doesn't seem acceptable
- * to me.
- * 3) record the mtime of the directory in the Path structure and
- * verify the directory hasn't changed since the contents were
- * hashed. This will catch the creation or deletion of files,
- * but not the updating of files. However, since it is the
- * creation and deletion that is the problem, this could be
- * a good thing to do. Unfortunately, if the directory (say ".")
- * were fairly large and changed fairly frequently, the constant
- * rehashing could seriously degrade performance. It might be
- * good in such cases to keep track of the number of rehashes
- * and if the number goes over a (small) limit, resort to using
- * stat in its place.
- *
- * An additional thing to consider is that pmake is used primarily
- * to create C programs and until recently pcc-based compilers refused
- * to allow you to specify where the resulting object file should be
- * placed. This forced all objects to be created in the current
- * directory. This isn't meant as a full excuse, just an explanation of
- * some of the reasons for the caching used here.
- *
- * One more note: the location of a target's file is only performed
- * on the downward traversal of the graph and then only for terminal
- * nodes in the graph. This could be construed as wrong in some cases,
- * but prevents inadvertent modification of files when the "installed"
- * directory for a file is provided in the search path.
- *
- * Another data structure maintained by this module is an mtime
- * cache used when the searching of cached directories fails to find
- * a file. In the past, Dir_FindFile would simply perform an access()
- * call in such a case to determine if the file could be found using
- * just the name given. When this hit, however, all that was gained
- * was the knowledge that the file existed. Given that an access() is
- * essentially a stat() without the copyout() call, and that the same
- * filesystem overhead would have to be incurred in Dir_MTime, it made
- * sense to replace the access() with a stat() and record the mtime
- * in a cache for when Dir_MTime was actually called.

+/*
+ * A search path consists of a Lst of Path structures. A Path structure
+ * has in it the name of the directory and a hash table of all the files
+ * in the directory. This is used to cut down on the number of system
+ * calls necessary to find implicit dependents and their like. Since
+ * these searches are made before any actions are taken, we need not
+ * worry about the directory changing due to creation commands. If this
+ * hampers the style of some makefiles, they must be changed.
+ *
+ * A list of all previously-read directories is kept in the
+ * openDirectories Lst. This list is checked first before a directory
+ * is opened.
+ *
+ * The need for the caching of whole directories is brought about by
+ * the multi-level transformation code in suff.c, which tends to search
+ * for far more files than regular make does. In the initial
+ * implementation, the amount of time spent performing "stat" calls was
+ * truly astronomical. The problem with hashing at the start is,
+ * of course, that pmake doesn't then detect changes to these directories
+ * during the course of the make. Three possibilities suggest themselves:
+ *
+ * 1) just use stat to test for a file's existence. As mentioned
+ * above, this is very inefficient due to the number of checks
+ * engendered by the multi-level transformation code.
+ * 2) use readdir() and company to search the directories, keeping
+ * them open between checks. I have tried this and while it
+ * didn't slow down the process too much, it could severely
+ * affect the amount of parallelism available as each directory
+ * open would take another file descriptor out of play for
+ * handling I/O for another job. Given that it is only recently
+ * that UNIX OS's have taken to allowing more than 20 or 32
+ * file descriptors for a process, this doesn't seem acceptable
+ * to me.
+ * 3) record the mtime of the directory in the Path structure and
+ * verify the directory hasn't changed since the contents were
+ * hashed. This will catch the creation or deletion of files,
+ * but not the updating of files. However, since it is the
+ * creation and deletion that is the problem, this could be
+ * a good thing to do. Unfortunately, if the directory (say ".")
+ * were fairly large and changed fairly frequently, the constant
+ * rehashing could seriously degrade performance. It might be
+ * good in such cases to keep track of the number of rehashes
+ * and if the number goes over a (small) limit, resort to using
+ * stat in its place.
+ *
+ * An additional thing to consider is that pmake is used primarily
+ * to create C programs and until recently pcc-based compilers refused
+ * to allow you to specify where the resulting object file should be
+ * placed. This forced all objects to be created in the current
+ * directory. This isn't meant as a full excuse, just an explanation of
+ * some of the reasons for the caching used here.
+ *
+ * One more note: the location of a target's file is only performed
+ * on the downward traversal of the graph and then only for terminal
+ * nodes in the graph. This could be construed as wrong in some cases,
+ * but prevents inadvertent modification of files when the "installed"
+ * directory for a file is provided in the search path.
+ *
+ * Another data structure maintained by this module is an mtime
+ * cache used when the searching of cached directories fails to find
+ * a file. In the past, Dir_FindFile would simply perform an access()
+ * call in such a case to determine if the file could be found using
+ * just the name given. When this hit, however, all that was gained
+ * was the knowledge that the file existed. Given that an access() is
+ * essentially a stat() without the copyout() call, and that the same
+ * filesystem overhead would have to be incurred in Dir_MTime, it made
+ * sense to replace the access() with a stat() and record the mtime
+ * in a cache for when Dir_MTime was actually called.

- * FAILURE if the spec was incorrect.
- *
- * Job_Finish Perform any final processing which needs doing.
- * This includes the execution of any commands

-.Sh NAME
-.Nm make
-.Nd maintain program dependencies
-.Sh SYNOPSIS
-.Nm
-.Op Fl BeikNnqrstWwX
-.Op Fl C Ar directory
-.Op Fl D Ar variable
-.Op Fl d Ar flags
-.Op Fl f Ar makefile
-.Op Fl I Ar directory
-.Op Fl J Ar private
-.Op Fl j Ar max_jobs
-.Op Fl m Ar directory
-.Op Fl T Ar file
-.Op Fl V Ar variable
-.Op Ar variable=value
-.Op Ar target ...
-.Sh DESCRIPTION
-.Nm
-is a program designed to simplify the maintenance of other programs.
-Its input is a list of specifications as to the files upon which programs
-and other files depend.
-If no
-.Fl f Ar makefile
-makefile option is given,
-.Nm
-will try to open
-.Ql Pa makefile
-then
-.Ql Pa Makefile
-in order to find the specifications.
-If the file
-.Ql Pa .depend
-exists, it is read (see
-.Xr mkdep 1 ) .
-.Pp
-This manual page is intended as a reference document only.
-For a more thorough description of
-.Nm
-and makefiles, please refer to
-.%T "PMake \- A Tutorial" .
-.Pp
-.Nm
-will prepend the contents of the
-.Va MAKEFLAGS
-environment variable to the command line arguments before parsing them.
-.Pp
-The options are as follows:
-.Bl -tag -width Ds
-.It Fl B
-Try to be backwards compatible by executing a single shell per command and
-by executing the commands to make the sources of a dependency line in sequence.
-.It Fl C Ar directory
-Change to
-.Ar directory
-before reading the makefiles or doing anything else.
-If multiple
-.Fl C
-options are specified, each is interpreted relative to the previous one:
-.Fl C Pa / Fl C Pa etc
-is equivalent to
-.Fl C Pa /etc .
-.It Fl D Ar variable
-Define
-.Ar variable
-to be 1, in the global context.
-.It Fl d Ar [-]flags
-Turn on debugging, and specify which portions of
-.Nm
-are to print debugging information.
-Unless the flags are preceded by
-.Ql \-
-they are added to the
-.Va MAKEFLAGS
-environment variable and will be processed by any child make processes.
-By default, debugging information is printed to standard error,
-but this can be changed using the
-.Ar F
-debugging flag.
-The debugging output is always unbuffered; in addition, if debugging
-is enabled but debugging output is not directed to standard output,
-then the standard output is line buffered.
-.Ar Flags
-is one or more of the following:
-.Bl -tag -width Ds
-.It Ar A
-Print all possible debugging information;
-equivalent to specifying all of the debugging flags.
-.It Ar a
-Print debugging information about archive searching and caching.
-.It Ar C
-Print debugging information about current working directory.
-.It Ar c
-Print debugging information about conditional evaluation.
-.It Ar d
-Print debugging information about directory searching and caching.
-.It Ar e
-Print debugging information about failed commands and targets.
-.It Ar F Ns Oo Sy \&+ Oc Ns Ar filename
-Specify where debugging output is written.
-This must be the last flag, because it consumes the remainder of
-the argument.
-If the character immediately after the
-.Ql F
-flag is
-.Ql \&+ ,
-then the file will be opened in append mode;
-otherwise the file will be overwritten.
-If the file name is
-.Ql stdout
-or
-.Ql stderr
-then debugging output will be written to the
-standard output or standard error output file descriptors respectively
-(and the
-.Ql \&+
-option has no effect).
-Otherwise, the output will be written to the named file.
-If the file name ends
-.Ql .%d
-then the
-.Ql %d
-is replaced by the pid.
-.It Ar f
-Print debugging information about loop evaluation.
-.It Ar "g1"
-Print the input graph before making anything.
-.It Ar "g2"
-Print the input graph after making everything, or before exiting
-on error.
-.It Ar "g3"
-Print the input graph before exiting on error.
-.It Ar j
-Print debugging information about running multiple shells.
-.It Ar l
-Print commands in Makefiles regardless of whether or not they are prefixed by
-.Ql @
-or other "quiet" flags.
-Also known as "loud" behavior.
-.It Ar M
-Print debugging information about "meta" mode decisions about targets.
-.It Ar m
-Print debugging information about making targets, including modification
-dates.
-.It Ar n
-Don't delete the temporary command scripts created when running commands.
-These temporary scripts are created in the directory
-referred to by the
-.Ev TMPDIR
-environment variable, or in
-.Pa /tmp
-if
-.Ev TMPDIR
-is unset or set to the empty string.
-The temporary scripts are created by
-.Xr mkstemp 3 ,
-and have names of the form
-.Pa makeXXXXXX .
-.Em NOTE :
-This can create many files in
-.Ev TMPDIR
-or
-.Pa /tmp ,
-so use with care.
-.It Ar p
-Print debugging information about makefile parsing.
-.It Ar s
-Print debugging information about suffix-transformation rules.
-.It Ar t
-Print debugging information about target list maintenance.
-.It Ar V
-Force the
-.Fl V
-option to print raw values of variables.
-.It Ar v
-Print debugging information about variable assignment.
-.It Ar w
-Print entering and leaving directory messages, pre and post processing.
-.It Ar x
-Run shell commands with
-.Fl x
-so the actual commands are printed as they are executed.
-.El
-.It Fl e
-Specify that environment variables override macro assignments within
-makefiles.
-.It Fl f Ar makefile
-Specify a makefile to read instead of the default
-.Ql Pa makefile .
-If
-.Ar makefile
-is
-.Ql Fl ,
-standard input is read.
-Multiple makefiles may be specified, and are read in the order specified.
-.It Fl I Ar directory
-Specify a directory in which to search for makefiles and included makefiles.
-The system makefile directory (or directories, see the
-.Fl m
-option) is automatically included as part of this list.
-.It Fl i
-Ignore non-zero exit of shell commands in the makefile.
-Equivalent to specifying
-.Ql Fl
-before each command line in the makefile.
-.It Fl J Ar private
-This option should
-.Em not
-be specified by the user.
-.Pp
-When the
-.Ar j
-option is in use in a recursive build, this option is passed by a make
-to child makes to allow all the make processes in the build to
-cooperate to avoid overloading the system.
-.It Fl j Ar max_jobs
-Specify the maximum number of jobs that
-.Nm
-may have running at any one time.
-The value is saved in
-.Va .MAKE.JOBS .
-Turns compatibility mode off, unless the
-.Ar B
-flag is also specified.
-When compatibility mode is off, all commands associated with a
-target are executed in a single shell invocation as opposed to the
-traditional one shell invocation per line.
-This can break traditional scripts which change directories on each
-command invocation and then expect to start with a fresh environment
-on the next line.
-It is more efficient to correct the scripts rather than turn backwards
-compatibility on.
-.It Fl k
-Continue processing after errors are encountered, but only on those targets
-that do not depend on the target whose creation caused the error.
-.It Fl m Ar directory
-Specify a directory in which to search for sys.mk and makefiles included
-via the
-.Ao Ar file Ac Ns -style
-include statement.
-The
-.Fl m
-option can be used multiple times to form a search path.
-This path will override the default system include path: /usr/share/mk.
-Furthermore the system include path will be appended to the search path used
-for
-.Qo Ar file Qc Ns -style
-include statements (see the
-.Fl I
-option).
-.Pp
-If a file or directory name in the
-.Fl m
-argument (or the
-.Ev MAKESYSPATH
-environment variable) starts with the string
-.Qq \&.../
-then
-.Nm
-will search for the specified file or directory named in the remaining part
-of the argument string.
-The search starts with the current directory of
-the Makefile and then works upward towards the root of the filesystem.
-If the search is successful, then the resulting directory replaces the
-.Qq \&.../
-specification in the
-.Fl m
-argument.
-If used, this feature allows
-.Nm
-to easily search in the current source tree for customized sys.mk files
-(e.g., by using
-.Qq \&.../mk/sys.mk
-as an argument).
-.It Fl n
-Display the commands that would have been executed, but do not
-actually execute them unless the target depends on the .MAKE special
-source (see below).
-.It Fl N
-Display the commands which would have been executed, but do not
-actually execute any of them; useful for debugging top-level makefiles
-without descending into subdirectories.
-.It Fl q
-Do not execute any commands, but exit 0 if the specified targets are
-up-to-date and 1, otherwise.
-.It Fl r
-Do not use the built-in rules specified in the system makefile.
-.It Fl s
-Do not echo any commands as they are executed.
-Equivalent to specifying
-.Ql Ic @
-before each command line in the makefile.
-.It Fl T Ar tracefile
-When used with the
-.Fl j
-flag,
-append a trace record to
-.Ar tracefile
-for each job started and completed.
-.It Fl t
-Rather than re-building a target as specified in the makefile, create it
-or update its modification time to make it appear up-to-date.
-.It Fl V Ar variable
-Print
-.Nm Ns 's
-idea of the value of
-.Ar variable ,
-in the global context.
-Do not build any targets.
-Multiple instances of this option may be specified;
-the variables will be printed one per line,
-with a blank line for each null or undefined variable.
-If
-.Ar variable
-contains a
-.Ql \&$
-then the value will be expanded before printing.
-.It Fl W
-Treat any warnings during makefile parsing as errors.
-.It Fl X
-Don't export variables passed on the command line to the environment
-individually.
-Variables passed on the command line are still exported
-via the
-.Va MAKEFLAGS
-environment variable.
-This option may be useful on systems which have a small limit on the
-size of command arguments.
-.It Ar variable=value
-Set the value of the variable
-.Ar variable
-to
-.Ar value .
-Normally, all values passed on the command line are also exported to
-sub-makes in the environment.
-The
-.Fl X
-flag disables this behavior.
-Variable assignments should follow options for POSIX compatibility
-but no ordering is enforced.
-.El
-.Pp
-There are seven different types of lines in a makefile: file dependency
-specifications, shell commands, variable assignments, include statements,
-conditional directives, for loops, and comments.
-.Pp
-In general, lines may be continued from one line to the next by ending
-them with a backslash
-.Pq Ql \e .
-The trailing newline character and initial whitespace on the following
-line are compressed into a single space.
-.Sh FILE DEPENDENCY SPECIFICATIONS
-Dependency lines consist of one or more targets, an operator, and zero
-or more sources.
-This creates a relationship where the targets
-.Dq depend
-on the sources
-and are usually created from them.
-The exact relationship between the target and the source is determined
-by the operator that separates them.
-The three operators are as follows:
-.Bl -tag -width flag
-.It Ic \&:
-A target is considered out-of-date if its modification time is less than
-those of any of its sources.
-Sources for a target accumulate over dependency lines when this operator
-is used.
-The target is removed if
-.Nm
-is interrupted.
-.It Ic \&!
-Targets are always re-created, but not until all sources have been
-examined and re-created as necessary.
-Sources for a target accumulate over dependency lines when this operator
-is used.
-The target is removed if
-.Nm
-is interrupted.
-.It Ic \&::
-If no sources are specified, the target is always re-created.
-Otherwise, a target is considered out-of-date if any of its sources has
-been modified more recently than the target.
-Sources for a target do not accumulate over dependency lines when this
-operator is used.
-The target will not be removed if
-.Nm
-is interrupted.
-.El
-.Pp
-Targets and sources may contain the shell wildcard values
-.Ql \&? ,
-.Ql * ,
-.Ql [] ,
-and
-.Ql {} .
-The values
-.Ql \&? ,
-.Ql * ,
-and
-.Ql []
-may only be used as part of the final
-component of the target or source, and must be used to describe existing
-files.
-The value
-.Ql {}
-need not necessarily be used to describe existing files.
-Expansion is in directory order, not alphabetically as done in the shell.
-.Sh SHELL COMMANDS
-Each target may have associated with it a series of shell commands, normally
-used to create the target.
-Each of the commands in this script
-.Em must
-be preceded by a tab.
-While any target may appear on a dependency line, only one of these
-dependencies may be followed by a creation script, unless the
-.Ql Ic \&::
-operator is used.
-.Pp
-If the first characters of the command line are any combination of
-.Ql Ic @ ,
-.Ql Ic + ,
-or
-.Ql Ic \- ,
-the command is treated specially.
-A
-.Ql Ic @
-causes the command not to be echoed before it is executed.
-A
-.Ql Ic +
-causes the command to be executed even when
-.Fl n
-is given.
-This is similar to the effect of the .MAKE special source,
-except that the effect can be limited to a single line of a script.
-A
-.Ql Ic \-
-causes any non-zero exit status of the command line to be ignored.
-.Pp
-When
-.Nm
-is run in jobs mode with
-.Fl j Ar max_jobs ,
-the entire script for the target is fed to a
-single instance of the shell.
-.Pp
-In compatibility (non-jobs) mode, each command is run in a separate process.
-If the command contains any shell meta characters
-.Pq Ql #=|^(){};&<>*?[]:$`\e\en
-it will be passed to the shell, otherwise
-.Nm
-will attempt direct execution.
-.Pp
-Since
-.Nm
-will
-.Xr chdir 2
-to
-.Ql Va .OBJDIR
-before executing any targets, each child process
-starts with that as its current working directory.
-.Pp
-Makefiles should be written so that the mode of
-.Nm
-operation does not change their behavior.
-For example, any command which needs to use
-.Dq cd
-or
-.Dq chdir ,
-without side-effect should be put in parenthesis:
-.Bd -literal -offset indent
-
-avoid-chdir-side-effects:
- @echo Building $@ in `pwd`
- @(cd ${.CURDIR} && ${.MAKE} $@)
- @echo Back in `pwd`
-
-ensure-one-shell-regardless-of-mode:
- @echo Building $@ in `pwd`; \\
- (cd ${.CURDIR} && ${.MAKE} $@); \\
- echo Back in `pwd`
-.Ed
-.Sh VARIABLE ASSIGNMENTS
-Variables in make are much like variables in the shell, and, by tradition,
-consist of all upper-case letters.
-.Ss Variable assignment modifiers
-The five operators that can be used to assign values to variables are as
-follows:
-.Bl -tag -width Ds
-.It Ic \&=
-Assign the value to the variable.
-Any previous value is overridden.
-.It Ic \&+=
-Append the value to the current value of the variable.
-.It Ic \&?=
-Assign the value to the variable if it is not already defined.
-.It Ic \&:=
-Assign with expansion, i.e. expand the value before assigning it
-to the variable.
-Normally, expansion is not done until the variable is referenced.
-.Em NOTE :
-References to undefined variables are
-.Em not
-expanded.
-This can cause problems when variable modifiers are used.
-.It Ic \&!=
-Expand the value and pass it to the shell for execution and assign
-the result to the variable.
-Any newlines in the result are replaced with spaces.
-.El
-.Pp
-Any white-space before the assigned
-.Ar value
-is removed; if the value is being appended, a single space is inserted
-between the previous contents of the variable and the appended value.
-.Pp
-Variables are expanded by surrounding the variable name with either
-curly braces
-.Pq Ql {}
-or parentheses
-.Pq Ql ()
-and preceding it with
-a dollar sign
-.Pq Ql \&$ .
-If the variable name contains only a single letter, the surrounding
-braces or parentheses are not required.
-This shorter form is not recommended.
-.Pp
-If the variable name contains a dollar, then the name itself is expanded first.
-This allows almost arbitrary variable names, however names containing dollar,
-braces, parenthesis, or whitespace are really best avoided!
-.Pp
-If the result of expanding a variable contains a dollar sign
-.Pq Ql \&$
-the string is expanded again.
-.Pp
-Variable substitution occurs at three distinct times, depending on where
-the variable is being used.
-.Bl -enum
-.It
-Variables in dependency lines are expanded as the line is read.
-.It
-Variables in shell commands are expanded when the shell command is
-executed.
-.It
-.Dq .for
-loop index variables are expanded on each loop iteration.
-Note that other variables are not expanded inside loops so
-the following example code:
-.Bd -literal -offset indent
-
-.Dv .for i in 1 2 3
-a+= ${i}
-j= ${i}
-b+= ${j}
-.Dv .endfor
-
-all:
- @echo ${a}
- @echo ${b}
-
-.Ed
-will print:
-.Bd -literal -offset indent
-1 2 3
-3 3 3
-
-.Ed
-Because while ${a} contains
-.Dq 1 2 3
-after the loop is executed, ${b}
-contains
-.Dq ${j} ${j} ${j}
-which expands to
-.Dq 3 3 3
-since after the loop completes ${j} contains
-.Dq 3 .
-.El
-.Ss Variable classes
-The four different classes of variables (in order of increasing precedence)
-are:
-.Bl -tag -width Ds
-.It Environment variables
-Variables defined as part of
-.Nm Ns 's
-environment.
-.It Global variables
-Variables defined in the makefile or in included makefiles.
-.It Command line variables
-Variables defined as part of the command line.
-.It Local variables
-Variables that are defined specific to a certain target.
-The seven local variables are as follows:
-.Bl -tag -width ".ARCHIVE"
-.It Va .ALLSRC
-The list of all sources for this target; also known as
-.Ql Va \&\*[Gt] .
-.It Va .ARCHIVE
-The name of the archive file.
-.It Va .IMPSRC
-In suffix-transformation rules, the name/path of the source from which the
-target is to be transformed (the
-.Dq implied
-source); also known as
-.Ql Va \&\*[Lt] .
-It is not defined in explicit rules.
-.It Va .MEMBER
-The name of the archive member.
-.It Va .OODATE
-The list of sources for this target that were deemed out-of-date; also
-known as
-.Ql Va \&? .
-.It Va .PREFIX
-The file prefix of the target, containing only the file portion, no suffix
-or preceding directory components; also known as
-.Ql Va * .
-.It Va .TARGET
-The name of the target; also known as
-.Ql Va @ .
-.El
-.Pp
-The shorter forms
-.Ql Va @ ,
-.Ql Va \&? ,
-.Ql Va \&\*[Lt] ,
-.Ql Va \&\*[Gt] ,
-and
-.Ql Va *
-are permitted for backward
-compatibility with historical makefiles and are not recommended.
-The six variables
-.Ql Va "@F" ,
-.Ql Va "@D" ,
-.Ql Va "\*[Lt]F" ,
-.Ql Va "\*[Lt]D" ,
-.Ql Va "*F" ,
-and
-.Ql Va "*D"
-are permitted for compatibility with
-.At V
-makefiles and are not recommended.
-.Pp
-Four of the local variables may be used in sources on dependency lines
-because they expand to the proper value for each target on the line.
-These variables are
-.Ql Va .TARGET ,
-.Ql Va .PREFIX ,
-.Ql Va .ARCHIVE ,
-and
-.Ql Va .MEMBER .
-.El
-.Ss Additional built-in variables
-In addition,
-.Nm
-sets or knows about the following variables:
-.Bl -tag -width .MAKEOVERRIDES
-.It Va \&$
-A single dollar sign
-.Ql \&$ ,
-i.e.
-.Ql \&$$
-expands to a single dollar
-sign.
-.It Va .ALLTARGETS
-The list of all targets encountered in the Makefile.
-If evaluated during
-Makefile parsing, lists only those targets encountered thus far.
-.It Va .CURDIR
-A path to the directory where
-.Nm
-was executed.
-Refer to the description of
-.Ql Ev PWD
-for more details.
-.It Va .INCLUDEDFROMDIR
-The directory of the file this Makefile was included from.
-.It Va .INCLUDEDFROMFILE
-The filename of the file this Makefile was included from.
-.It Ev MAKE
-The name that
-.Nm
-was executed with
-.Pq Va argv[0] .
-For compatibility
-.Nm
-also sets
-.Va .MAKE
-with the same value.
-The preferred variable to use is the environment variable
-.Ev MAKE
-because it is more compatible with other versions of
-.Nm
-and cannot be confused with the special target with the same name.
-.It Va .MAKE.DEPENDFILE
-Names the makefile (default
-.Ql Pa .depend )
-from which generated dependencies are read.
-.It Va .MAKE.EXPAND_VARIABLES
-A boolean that controls the default behavior of the
-.Fl V
-option.
-.It Va .MAKE.EXPORTED
-The list of variables exported by
-.Nm .
-.It Va .MAKE.JOBS
-The argument to the
-.Fl j
-option.
-.It Va .MAKE.JOB.PREFIX
-If
-.Nm
-is run with
-.Ar j
-then output for each target is prefixed with a token
-.Ql --- target ---
-the first part of which can be controlled via
-.Va .MAKE.JOB.PREFIX .
-If
-.Va .MAKE.JOB.PREFIX
-is empty, no token is printed.
-.br
-For example:
-.Li .MAKE.JOB.PREFIX=${.newline}---${.MAKE:T}[${.MAKE.PID}]
-would produce tokens like
-.Ql ---make[1234] target ---
-making it easier to track the degree of parallelism being achieved.
-.It Ev MAKEFLAGS
-The environment variable
-.Ql Ev MAKEFLAGS
-may contain anything that
-may be specified on
-.Nm Ns 's
-command line.
-Anything specified on
-.Nm Ns 's
-command line is appended to the
-.Ql Ev MAKEFLAGS
-variable which is then
-entered into the environment for all programs which
-.Nm
-executes.
-.It Va .MAKE.LEVEL
-The recursion depth of
-.Nm .
-The initial instance of
-.Nm
-will be 0, and an incremented value is put into the environment
-to be seen by the next generation.
-This allows tests like:
-.Li .if ${.MAKE.LEVEL} == 0
-to protect things which should only be evaluated in the initial instance of
-.Nm .
-.It Va .MAKE.MAKEFILE_PREFERENCE
-The ordered list of makefile names
-(default
-.Ql Pa makefile ,
-.Ql Pa Makefile )
-that
-.Nm
-will look for.
-.It Va .MAKE.MAKEFILES
-The list of makefiles read by
-.Nm ,
-which is useful for tracking dependencies.
-Each makefile is recorded only once, regardless of the number of times read.
-.It Va .MAKE.MODE
-Processed after reading all makefiles.
-Can affect the mode that
-.Nm
-runs in.
-It can contain a number of keywords:
-.Bl -hang -width ignore-cmd
-.It Pa compat
-Like
-.Fl B ,
-puts
-.Nm
-into "compat" mode.
-.It Pa meta
-Puts
-.Nm
-into "meta" mode, where meta files are created for each target
-to capture the command run, the output generated and if
-.Xr filemon 4
-is available, the system calls which are of interest to
-.Nm .
-The captured output can be very useful when diagnosing errors.
-.It Pa curdirOk= Ar bf
-Normally
-.Nm
-will not create .meta files in
-.Ql Va .CURDIR .
-This can be overridden by setting
-.Va bf
-to a value which represents True.
-.It Pa env
-For debugging, it can be useful to inlcude the environment
-in the .meta file.
-.It Pa verbose
-If in "meta" mode, print a clue about the target being built.
-This is useful if the build is otherwise running silently.
-The message printed the value of:
-.Va .MAKE.META.PREFIX .
-.It Pa ignore-cmd
-Some makefiles have commands which are simply not stable.
-This keyword causes them to be ignored for
-determining whether a target is out of date in "meta" mode.
-See also
-.Ic .NOMETA_CMP .
-.It Pa silent= Ar bf
-If
-.Va bf
-is True, when a .meta file is created, mark the target
-.Ic .SILENT .
-.El
-.It Va .MAKE.META.BAILIWICK
-In "meta" mode, provides a list of prefixes which
-match the directories controlled by
-.Nm .
-If a file that was generated outside of
-.Va .OBJDIR
-but within said bailiwick is missing,
-the current target is considered out-of-date.
-.It Va .MAKE.META.CREATED
-In "meta" mode, this variable contains a list of all the meta files
-updated.
-If not empty, it can be used to trigger processing of
-.Va .MAKE.META.FILES .
-.It Va .MAKE.META.FILES
-In "meta" mode, this variable contains a list of all the meta files
-used (updated or not).
-This list can be used to process the meta files to extract dependency
-information.
-.It Va .MAKE.META.IGNORE_PATHS
-Provides a list of path prefixes that should be ignored;
-because the contents are expected to change over time.
-The default list includes:
-.Ql Pa /dev /etc /proc /tmp /var/run /var/tmp
-.It Va .MAKE.META.PREFIX
-Defines the message printed for each meta file updated in "meta verbose" mode.
-The default value is:
-.Dl Building ${.TARGET:H:tA}/${.TARGET:T}
-.It Va .MAKEOVERRIDES
-This variable is used to record the names of variables assigned to
-on the command line, so that they may be exported as part of
-.Ql Ev MAKEFLAGS .
-This behaviour can be disabled by assigning an empty value to
-.Ql Va .MAKEOVERRIDES
-within a makefile.
-Extra variables can be exported from a makefile
-by appending their names to
-.Ql Va .MAKEOVERRIDES .
-.Ql Ev MAKEFLAGS
-is re-exported whenever
-.Ql Va .MAKEOVERRIDES
-is modified.
-.It Va .MAKE.PATH_FILEMON
-If
-.Nm
-was built with
-.Xr filemon 4
-support, this is set to the path of the device node.
-This allows makefiles to test for this support.
-.It Va .MAKE.PID
-The process-id of
-.Nm .
-.It Va .MAKE.PPID
-The parent process-id of
-.Nm .
-.It Va MAKE_PRINT_VAR_ON_ERROR
-When
-.Nm
-stops due to an error, it prints its name and the value of
-.Ql Va .CURDIR
-as well as the value of any variables named in
-.Ql Va MAKE_PRINT_VAR_ON_ERROR .
-.It Va .newline
-This variable is simply assigned a newline character as its value.
-This allows expansions using the
-.Cm \&:@
-modifier to put a newline between
-iterations of the loop rather than a space.
-For example, the printing of
-.Ql Va MAKE_PRINT_VAR_ON_ERROR
-could be done as ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@}.
-.It Va .OBJDIR
-A path to the directory where the targets are built.
-Its value is determined by trying to
-.Xr chdir 2
-to the following directories in order and using the first match:
-.Bl -enum
-.It
-.Ev ${MAKEOBJDIRPREFIX}${.CURDIR}
-.Pp
-(Only if
-.Ql Ev MAKEOBJDIRPREFIX
-is set in the environment or on the command line.)
-.It
-.Ev ${MAKEOBJDIR}
-.Pp
-(Only if
-.Ql Ev MAKEOBJDIR
-is set in the environment or on the command line.)
-.It
-.Ev ${.CURDIR} Ns Pa /obj. Ns Ev ${MACHINE}
-.It
-.Ev ${.CURDIR} Ns Pa /obj
-.It
-.Pa /usr/obj/ Ns Ev ${.CURDIR}
-.It
-.Ev ${.CURDIR}
-.El
-.Pp
-Variable expansion is performed on the value before it's used,
-so expressions such as
-.Dl ${.CURDIR:S,^/usr/src,/var/obj,}
-may be used.
-This is especially useful with
-.Ql Ev MAKEOBJDIR .
-.Pp
-.Ql Va .OBJDIR
-may be modified in the makefile as a global variable.
-In all cases,
-.Nm
-will
-.Xr chdir 2
-to
-.Ql Va .OBJDIR
-and set
-.Ql Ev PWD
-to that directory before executing any targets.
-.
-.It Va .PARSEDIR
-A path to the directory of the current
-.Ql Pa Makefile
-being parsed.
-.It Va .PARSEFILE
-The basename of the current
-.Ql Pa Makefile
-being parsed.
-This variable and
-.Ql Va .PARSEDIR
-are both set only while the
-.Ql Pa Makefiles
-are being parsed.
-If you want to retain their current values, assign them to a variable
-using assignment with expansion:
-.Pq Ql Cm \&:= .
-.It Va .PATH
-A variable that represents the list of directories that
-.Nm
-will search for files.
-The search list should be updated using the target
-.Ql Va .PATH
-rather than the variable.
-.It Ev PWD
-Alternate path to the current directory.
-.Nm
-normally sets
-.Ql Va .CURDIR
-to the canonical path given by
-.Xr getcwd 3 .
-However, if the environment variable
-.Ql Ev PWD
-is set and gives a path to the current directory, then
-.Nm
-sets
-.Ql Va .CURDIR
-to the value of
-.Ql Ev PWD
-instead.
-This behaviour is disabled if
-.Ql Ev MAKEOBJDIRPREFIX
-is set or
-.Ql Ev MAKEOBJDIR
-contains a variable transform.
-.Ql Ev PWD
-is set to the value of
-.Ql Va .OBJDIR
-for all programs which
-.Nm
-executes.
-.It Ev .TARGETS
-The list of targets explicitly specified on the command line, if any.
-.It Ev VPATH
-Colon-separated
-.Pq Dq \&:
-lists of directories that
-.Nm
-will search for files.
-The variable is supported for compatibility with old make programs only,
-use
-.Ql Va .PATH
-instead.
-.El
-.Ss Variable modifiers
-Variable expansion may be modified to select or modify each word of the
-variable (where a
-.Dq word
-is white-space delimited sequence of characters).
-The general format of a variable expansion is as follows:
-.Pp
-.Dl ${variable[:modifier[:...]]}
-.Pp
-Each modifier begins with a colon,
-which may be escaped with a backslash
-.Pq Ql \e .
-.Pp
-A set of modifiers can be specified via a variable, as follows:
-.Pp
-.Dl modifier_variable=modifier[:...]
-.Dl ${variable:${modifier_variable}[:...]}
-.Pp
-In this case the first modifier in the modifier_variable does not
-start with a colon, since that must appear in the referencing
-variable.
-If any of the modifiers in the modifier_variable contain a dollar sign
-.Pq Ql $ ,
-these must be doubled to avoid early expansion.
-.Pp
-The supported modifiers are:
-.Bl -tag -width EEE
-.It Cm \&:E
-Replaces each word in the variable with its suffix.
-.It Cm \&:H
-Replaces each word in the variable with everything but the last component.
-.It Cm \&:M Ns Ar pattern
-Select only those words that match
-.Ar pattern .
-The standard shell wildcard characters
-.Pf ( Ql * ,
-.Ql \&? ,
-and
-.Ql Oo Oc )
-may
-be used.
-The wildcard characters may be escaped with a backslash
-.Pq Ql \e .
-As a consequence of the way values are split into words, matched,
-and then joined, a construct like
-.Dl ${VAR:M*}
-will normalise the inter-word spacing, removing all leading and
-trailing space, and converting multiple consecutive spaces
-to single spaces.
-.
-.It Cm \&:N Ns Ar pattern
-This is identical to
-.Ql Cm \&:M ,
-but selects all words which do not match
-.Ar pattern .
-.It Cm \&:O
-Order every word in variable alphabetically.
-To sort words in
-reverse order use the
-.Ql Cm \&:O:[-1..1]
-combination of modifiers.
-.It Cm \&:Ox
-Randomize words in variable.
-The results will be different each time you are referring to the
-modified variable; use the assignment with expansion
-.Pq Ql Cm \&:=
-to prevent such behaviour.
-For example,
-.Bd -literal -offset indent
-LIST= uno due tre quattro
-RANDOM_LIST= ${LIST:Ox}
-STATIC_RANDOM_LIST:= ${LIST:Ox}
-
-all:
- @echo "${RANDOM_LIST}"
- @echo "${RANDOM_LIST}"
- @echo "${STATIC_RANDOM_LIST}"
- @echo "${STATIC_RANDOM_LIST}"
-.Ed
-may produce output similar to:
-.Bd -literal -offset indent
-quattro due tre uno
-tre due quattro uno
-due uno quattro tre
-due uno quattro tre
-.Ed
-.It Cm \&:Q
-Quotes every shell meta-character in the variable, so that it can be passed
-safely through recursive invocations of
-.Nm .
-.It Cm \&:R
-Replaces each word in the variable with everything but its suffix.
-.It Cm \&:gmtime
-The value is a format string for
-.Xr strftime 3 ,
-using the current
-.Xr gmtime 3 .
-.It Cm \&:hash
-Compute a 32bit hash of the value and encode it as hex digits.
-.It Cm \&:localtime
-The value is a format string for
-.Xr strftime 3 ,
-using the current
-.Xr localtime 3 .
-.It Cm \&:tA
-Attempt to convert variable to an absolute path using
-.Xr realpath 3 ,
-if that fails, the value is unchanged.
-.It Cm \&:tl
-Converts variable to lower-case letters.
-.It Cm \&:ts Ns Ar c
-Words in the variable are normally separated by a space on expansion.
-This modifier sets the separator to the character
-.Ar c .
-If
-.Ar c
-is omitted, then no separator is used.
-The common escapes (including octal numeric codes), work as expected.
-.It Cm \&:tu
-Converts variable to upper-case letters.
-.It Cm \&:tW
-Causes the value to be treated as a single word
-(possibly containing embedded white space).
-See also
-.Ql Cm \&:[*] .
-.It Cm \&:tw
-Causes the value to be treated as a sequence of
-words delimited by white space.
-See also
-.Ql Cm \&:[@] .
-.Sm off
-.It Cm \&:S No \&/ Ar old_string No \&/ Ar new_string No \&/ Op Cm 1gW
-.Sm on
-Modify the first occurrence of
-.Ar old_string
-in the variable's value, replacing it with
-.Ar new_string .
-If a
-.Ql g
-is appended to the last slash of the pattern, all occurrences
-in each word are replaced.
-If a
-.Ql 1
-is appended to the last slash of the pattern, only the first word
-is affected.
-If a
-.Ql W
-is appended to the last slash of the pattern,
-then the value is treated as a single word
-(possibly containing embedded white space).
-If
-.Ar old_string
-begins with a caret
-.Pq Ql ^ ,
-.Ar old_string
-is anchored at the beginning of each word.
-If
-.Ar old_string
-ends with a dollar sign
-.Pq Ql \&$ ,
-it is anchored at the end of each word.
-Inside
-.Ar new_string ,
-an ampersand
-.Pq Ql \*[Am]
-is replaced by
-.Ar old_string
-(without any
-.Ql ^
-or
-.Ql \&$ ) .
-Any character may be used as a delimiter for the parts of the modifier
-string.
-The anchoring, ampersand and delimiter characters may be escaped with a
-backslash
-.Pq Ql \e .
-.Pp
-Variable expansion occurs in the normal fashion inside both
-.Ar old_string
-and
-.Ar new_string
-with the single exception that a backslash is used to prevent the expansion
-of a dollar sign
-.Pq Ql \&$ ,
-not a preceding dollar sign as is usual.
-.Sm off
-.It Cm \&:C No \&/ Ar pattern No \&/ Ar replacement No \&/ Op Cm 1gW
-.Sm on
-The
-.Cm \&:C
-modifier is just like the
-.Cm \&:S
-modifier except that the old and new strings, instead of being
-simple strings, are an extended regular expression (see
-.Xr regex 3 )
-string
-.Ar pattern
-and an
-.Xr ed 1 Ns \-style
-string
-.Ar replacement .
-Normally, the first occurrence of the pattern
-.Ar pattern
-in each word of the value is substituted with
-.Ar replacement .
-The
-.Ql 1
-modifier causes the substitution to apply to at most one word; the
-.Ql g
-modifier causes the substitution to apply to as many instances of the
-search pattern
-.Ar pattern
-as occur in the word or words it is found in; the
-.Ql W
-modifier causes the value to be treated as a single word
-(possibly containing embedded white space).
-Note that
-.Ql 1
-and
-.Ql g
-are orthogonal; the former specifies whether multiple words are
-potentially affected, the latter whether multiple substitutions can
-potentially occur within each affected word.
-.Pp
-As for the
-.Cm \&:S
-modifier, the
-.Ar pattern
-and
-.Ar replacement
-are subjected to variable expansion before being parsed as
-regular expressions.
-.It Cm \&:T
-Replaces each word in the variable with its last component.
-.It Cm \&:u
-Remove adjacent duplicate words (like
-.Xr uniq 1 ) .
-.Sm off
-.It Cm \&:\&? Ar true_string Cm \&: Ar false_string
-.Sm on
-If the variable name (not its value), when parsed as a .if conditional
-expression, evaluates to true, return as its value the
-.Ar true_string ,
-otherwise return the
-.Ar false_string .
-Since the variable name is used as the expression, \&:\&? must be the
-first modifier after the variable name itself - which will, of course,
-usually contain variable expansions.
-A common error is trying to use expressions like
-.Dl ${NUMBERS:M42:?match:no}
-which actually tests defined(NUMBERS),
-to determine is any words match "42" you need to use something like:
-.Dl ${"${NUMBERS:M42}" != \&"\&":?match:no} .
-.It Ar :old_string=new_string
-This is the
-.At V
-style variable substitution.
-It must be the last modifier specified.
-If
-.Ar old_string
-or
-.Ar new_string
-do not contain the pattern matching character
-.Ar %
-then it is assumed that they are
-anchored at the end of each word, so only suffixes or entire
-words may be replaced.
-Otherwise
-.Ar %
-is the substring of
-.Ar old_string
-to be replaced in
-.Ar new_string .
-.Pp
-Variable expansion occurs in the normal fashion inside both
-.Ar old_string
-and
-.Ar new_string
-with the single exception that a backslash is used to prevent the
-expansion of a dollar sign
-.Pq Ql \&$ ,
-not a preceding dollar sign as is usual.
-.Sm off
-.It Cm \&:@ Ar temp Cm @ Ar string Cm @
-.Sm on
-This is the loop expansion mechanism from the OSF Development
-Environment (ODE) make.
-Unlike
-.Cm \&.for
-loops expansion occurs at the time of
-reference.
-Assign
-.Ar temp
-to each word in the variable and evaluate
-.Ar string .
-The ODE convention is that
-.Ar temp
-should start and end with a period.
-For example.
-.Dl ${LINKS:@.LINK.@${LN} ${TARGET} ${.LINK.}@}
-.Pp
-However a single character variable is often more readable:
-.Dl ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@}
-.It Cm \&:U Ns Ar newval
-If the variable is undefined
-.Ar newval
-is the value.
-If the variable is defined, the existing value is returned.
-This is another ODE make feature.
-It is handy for setting per-target CFLAGS for instance:
-.Dl ${_${.TARGET:T}_CFLAGS:U${DEF_CFLAGS}}
-If a value is only required if the variable is undefined, use:
-.Dl ${VAR:D:Unewval}
-.It Cm \&:D Ns Ar newval
-If the variable is defined
-.Ar newval
-is the value.
-.It Cm \&:L
-The name of the variable is the value.
-.It Cm \&:P
-The path of the node which has the same name as the variable
-is the value.
-If no such node exists or its path is null, then the
-name of the variable is used.
-In order for this modifier to work, the name (node) must at least have
-appeared on the rhs of a dependency.
-.Sm off
-.It Cm \&:\&! Ar cmd Cm \&!
-.Sm on
-The output of running
-.Ar cmd
-is the value.
-.It Cm \&:sh
-If the variable is non-empty it is run as a command and the output
-becomes the new value.
-.It Cm \&::= Ns Ar str
-The variable is assigned the value
-.Ar str
-after substitution.
-This modifier and its variations are useful in
-obscure situations such as wanting to set a variable when shell commands
-are being parsed.
-These assignment modifiers always expand to
-nothing, so if appearing in a rule line by themselves should be
-preceded with something to keep
-.Nm
-happy.
-.Pp
-The
-.Ql Cm \&::
-helps avoid false matches with the
-.At V
-style
-.Cm \&:=
-modifier and since substitution always occurs the
-.Cm \&::=
-form is vaguely appropriate.
-.It Cm \&::?= Ns Ar str
-As for
-.Cm \&::=
-but only if the variable does not already have a value.
-.It Cm \&::+= Ns Ar str
-Append
-.Ar str
-to the variable.
-.It Cm \&::!= Ns Ar cmd
-Assign the output of
-.Ar cmd
-to the variable.
-.It Cm \&:\&[ Ns Ar range Ns Cm \&]
-Selects one or more words from the value,
-or performs other operations related to the way in which the
-value is divided into words.
-.Pp
-Ordinarily, a value is treated as a sequence of words
-delimited by white space.
-Some modifiers suppress this behaviour,
-causing a value to be treated as a single word
-(possibly containing embedded white space).
-An empty value, or a value that consists entirely of white-space,
-is treated as a single word.
-For the purposes of the
-.Ql Cm \&:[]
-modifier, the words are indexed both forwards using positive integers
-(where index 1 represents the first word),
-and backwards using negative integers
-(where index \-1 represents the last word).
-.Pp
-The
-.Ar range
-is subjected to variable expansion, and the expanded result is
-then interpreted as follows:
-.Bl -tag -width index
-.\" :[n]
-.It Ar index
-Selects a single word from the value.
-.\" :[start..end]
-.It Ar start Ns Cm \&.. Ns Ar end
-Selects all words from
-.Ar start
-to
-.Ar end ,
-inclusive.
-For example,
-.Ql Cm \&:[2..-1]
-selects all words from the second word to the last word.
-If
-.Ar start
-is greater than
-.Ar end ,
-then the words are output in reverse order.
-For example,
-.Ql Cm \&:[-1..1]
-selects all the words from last to first.
-.\" :[*]
-.It Cm \&*
-Causes subsequent modifiers to treat the value as a single word
-(possibly containing embedded white space).
-Analogous to the effect of
-\&"$*\&"
-in Bourne shell.
-.\" :[0]
-.It 0
-Means the same as
-.Ql Cm \&:[*] .
-.\" :[*]
-.It Cm \&@
-Causes subsequent modifiers to treat the value as a sequence of words
-delimited by white space.
-Analogous to the effect of
-\&"$@\&"

-.\" :[#]
-.It Cm \&#
-Returns the number of words in the value.

-.Sh INCLUDE STATEMENTS, CONDITIONALS AND FOR LOOPS
-Makefile inclusion, conditional structures and for loops reminiscent
-of the C programming language are provided in
-.Nm .
-All such structures are identified by a line beginning with a single
-dot
-.Pq Ql \&.
-character.
-Files are included with either
-.Cm \&.include Aq Ar file
-or
-.Cm \&.include Pf \*q Ar file Ns \*q .
-Variables between the angle brackets or double quotes are expanded
-to form the file name.
-If angle brackets are used, the included makefile is expected to be in
-the system makefile directory.
-If double quotes are used, the including makefile's directory and any
-directories specified using the
-.Fl I
-option are searched before the system
-makefile directory.
-For compatibility with other versions of
-.Nm
-.Ql include file ...
-is also accepted.
-If the include statement is written as
-.Cm .-include
-or as
-.Cm .sinclude
-then errors locating and/or opening include files are ignored.
-.Pp
-Conditional expressions are also preceded by a single dot as the first
-character of a line.
-The possible conditionals are as follows:
-.Bl -tag -width Ds
-.It Ic .error Ar message
-The message is printed along with the name of the makefile and line number,
-then
-.Nm
-will exit.
-.It Ic .export Ar variable ...
-Export the specified global variable.
-If no variable list is provided, all globals are exported
-except for internal variables (those that start with
-.Ql \&. ) .
-This is not affected by the
-.Fl X
-flag, so should be used with caution.
-For compatibility with other
-.Nm
-programs
-.Ql export variable=value
-is also accepted.
-.Pp
-Appending a variable name to

-is equivalent to exporting a variable.
-.It Ic .export-env Ar variable ...
-The same as

-except that the variable is not appended to
-.Va .MAKE.EXPORTED .
-This allows exporting a value to the environment which is different from that
-used by

-internally.
-.It Ic .info Ar message
-The message is printed along with the name of the makefile and line number.
-.It Ic .undef Ar variable
-Un-define the specified global variable.
-Only global variables may be un-defined.
-.It Ic .unexport Ar variable ...
-The opposite of
-.Ql .export .
-The specified global
-.Va variable
-will be removed from
-.Va .MAKE.EXPORTED .
-If no variable list is provided, all globals are unexported,
-and
-.Va .MAKE.EXPORTED
-deleted.
-.It Ic .unexport-env
-Unexport all globals previously exported and
-clear the environment inherited from the parent.
-This operation will cause a memory leak of the original environment,
-so should be used sparingly.
-Testing for
-.Va .MAKE.LEVEL
-being 0, would make sense.
-Also note that any variables which originated in the parent environment
-should be explicitly preserved if desired.
-For example:
-.Bd -literal -offset indent
-.Li .if ${.MAKE.LEVEL} == 0
-PATH := ${PATH}
-.Li .unexport-env
-.Li .export PATH
-.Li .endif
-.Pp
-.Ed
-Would result in an environment containing only

-values are compared.
-A value is interpreted as hexadecimal if it is
-preceded by 0x, otherwise it is decimal; octal numbers are not supported.
-The standard C relational operators are all supported.
-If after
-variable expansion, either the left or right hand side of a
-.Ql Ic ==
-or
-.Ql Ic "!="
-operator is not an integral value, then
-string comparison is performed between the expanded
-variables.
-If no relational operator is given, it is assumed that the expanded
-variable is being compared against 0 or an empty string in the case
-of a string comparison.
-.Pp
-When
-.Nm
-is evaluating one of these conditional expressions, and it encounters
-a (white-space separated) word it doesn't recognize, either the
-.Dq make
-or
-.Dq defined
-expression is applied to it, depending on the form of the conditional.
-If the form is
-.Ql Ic .ifdef ,
-.Ql Ic .ifndef ,
-or
-.Ql Ic .if
-the
-.Dq defined
-expression is applied.
-Similarly, if the form is
-.Ql Ic .ifmake
-or
-.Ql Ic .ifnmake , the
-.Dq make
-expression is applied.
-.Pp
-If the conditional evaluates to true the parsing of the makefile continues
-as before.
-If it evaluates to false, the following lines are skipped.
-In both cases this continues until a
-.Ql Ic .else
-or
-.Ql Ic .endif
-is found.
-.Pp
-For loops are typically used to apply a set of rules to a list of files.
-The syntax of a for loop is:
-.Pp
-.Bl -tag -compact -width Ds
-.It Ic \&.for Ar variable Oo Ar variable ... Oc Ic in Ar expression
-.It Aq make-rules
-.It Ic \&.endfor
-.El
-.Pp
-After the for
-.Ic expression
-is evaluated, it is split into words.
-On each iteration of the loop, one word is taken and assigned to each
-.Ic variable ,
-in order, and these
-.Ic variables
-are substituted into the
-.Ic make-rules
-inside the body of the for loop.
-The number of words must come out even; that is, if there are three
-iteration variables, the number of words provided must be a multiple
-of three.
-.Sh COMMENTS
-Comments begin with a hash
-.Pq Ql \&#
-character, anywhere but in a shell
-command line, and continue to the end of an unescaped new line.
-.Sh SPECIAL SOURCES (ATTRIBUTES)
-.Bl -tag -width .IGNOREx
-.It Ic .EXEC
-Target is never out of date, but always execute commands anyway.
-.It Ic .IGNORE
-Ignore any errors from the commands associated with this target, exactly
-as if they all were preceded by a dash
-.Pq Ql \- .
-.\" .It Ic .INVISIBLE
-.\" XXX
-.\" .It Ic .JOIN
-.\" XXX
-.It Ic .MADE
-Mark all sources of this target as being up-to-date.
-.It Ic .MAKE
-Execute the commands associated with this target even if the
-.Fl n
-or
-.Fl t
-options were specified.
-Normally used to mark recursive
-.Nm Ns s .
-.It Ic .META
-Create a meta file for the target, even if it is flagged as
-.Ic .PHONY ,
-.Ic .MAKE ,
-or
-.Ic .SPECIAL .
-Usage in conjunction with
-.Ic .MAKE
-is the most likely case.
-In "meta" mode, the target is out-of-date if the meta file is missing.
-.It Ic .NOMETA
-Do not create a meta file for the target.
-Meta files are also not created for
-.Ic .PHONY ,
-.Ic .MAKE ,
-or
-.Ic .SPECIAL
-targets.
-.It Ic .NOMETA_CMP
-Ignore differences in commands when deciding if target is out of date.
-This is useful if the command contains a value which always changes.
-If the number of commands change, though, the target will still be out of date.
-The same effect applies to any command line that uses the variable
-.Va .OODATE ,
-which can be used for that purpose even when not otherwise needed or desired:
-.Bd -literal -offset indent
-
-skip-compare-for-some:
- @echo this will be compared
- @echo this will not ${.OODATE:M.NOMETA_CMP}
- @echo this will also be compared
-
-.Ed
-The
-.Cm \&:M
-pattern suppresses any expansion of the unwanted variable.
-.It Ic .NOPATH
-Do not search for the target in the directories specified by
-.Ic .PATH .
-.It Ic .NOTMAIN
-Normally
-.Nm
-selects the first target it encounters as the default target to be built
-if no target was specified.
-This source prevents this target from being selected.
-.It Ic .OPTIONAL
-If a target is marked with this attribute and
-.Nm
-can't figure out how to create it, it will ignore this fact and assume
-the file isn't needed or already exists.
-.It Ic .PHONY
-The target does not
-correspond to an actual file; it is always considered to be out of date,
-and will not be created with the
-.Fl t
-option.
-Suffix-transformation rules are not applied to
-.Ic .PHONY
-targets.
-.It Ic .PRECIOUS
-When
-.Nm
-is interrupted, it normally removes any partially made targets.
-This source prevents the target from being removed.
-.It Ic .RECURSIVE
-Synonym for
-.Ic .MAKE .
-.It Ic .SILENT
-Do not echo any of the commands associated with this target, exactly
-as if they all were preceded by an at sign
-.Pq Ql @ .
-.It Ic .USE
-Turn the target into
-.Nm Ns 's
-version of a macro.
-When the target is used as a source for another target, the other target
-acquires the commands, sources, and attributes (except for
-.Ic .USE )
-of the
-source.
-If the target already has commands, the
-.Ic .USE
-target's commands are appended
-to them.
-.It Ic .USEBEFORE
-Exactly like
-.Ic .USE ,
-but prepend the
-.Ic .USEBEFORE
-target commands to the target.
-.It Ic .WAIT
-If
-.Ic .WAIT
-appears in a dependency line, the sources that precede it are
-made before the sources that succeed it in the line.
-Since the dependents of files are not made until the file itself
-could be made, this also stops the dependents being built unless they
-are needed for another branch of the dependency tree.
-So given:
-.Bd -literal
-x: a .WAIT b
- echo x
-a:
- echo a
-b: b1
- echo b
-b1:
- echo b1
-
-.Ed
-the output is always
-.Ql a ,
-.Ql b1 ,
-.Ql b ,
-.Ql x .
-.br
-The ordering imposed by
-.Ic .WAIT
-is only relevant for parallel makes.
-.El
-.Sh SPECIAL TARGETS
-Special targets may not be included with other targets, i.e. they must be
-the only target specified.
-.Bl -tag -width .BEGINx
-.It Ic .BEGIN
-Any command lines attached to this target are executed before anything
-else is done.
-.It Ic .DEFAULT
-This is sort of a
-.Ic .USE
-rule for any target (that was used only as a
-source) that
-.Nm
-can't figure out any other way to create.
-Only the shell script is used.
-The
-.Ic .IMPSRC
-variable of a target that inherits
-.Ic .DEFAULT Ns 's
-commands is set
-to the target's own name.
-.It Ic .END
-Any command lines attached to this target are executed after everything
-else is done.
-.It Ic .ERROR
-Any command lines attached to this target are executed when another target fails.
-The
-.Ic .ERROR_TARGET
-variable is set to the target that failed.
-See also
-.Ic MAKE_PRINT_VAR_ON_ERROR .
-.It Ic .IGNORE
-Mark each of the sources with the
-.Ic .IGNORE
-attribute.
-If no sources are specified, this is the equivalent of specifying the
-.Fl i
-option.
-.It Ic .INTERRUPT
-If
-.Nm
-is interrupted, the commands for this target will be executed.
-.It Ic .MAIN
-If no target is specified when
-.Nm
-is invoked, this target will be built.
-.It Ic .MAKEFLAGS
-This target provides a way to specify flags for
-.Nm
-when the makefile is used.
-The flags are as if typed to the shell, though the
-.Fl f
-option will have
-no effect.
-.\" XXX: NOT YET!!!!
-.\" .It Ic .NOTPARALLEL
-.\" The named targets are executed in non parallel mode.
-.\" If no targets are
-.\" specified, then all targets are executed in non parallel mode.
-.It Ic .NOPATH
-Apply the
-.Ic .NOPATH
-attribute to any specified sources.
-.It Ic .NOTPARALLEL
-Disable parallel mode.
-.It Ic .NO_PARALLEL
-Synonym for
-.Ic .NOTPARALLEL ,
-for compatibility with other pmake variants.
-.It Ic .ORDER
-The named targets are made in sequence.
-This ordering does not add targets to the list of targets to be made.
-Since the dependents of a target do not get built until the target itself
-could be built, unless
-.Ql a
-is built by another part of the dependency graph,
-the following is a dependency loop:
-.Bd -literal
-\&.ORDER: b a
-b: a
-.Ed
-.Pp
-The ordering imposed by
-.Ic .ORDER
-is only relevant for parallel makes.
-.\" XXX: NOT YET!!!!
-.\" .It Ic .PARALLEL
-.\" The named targets are executed in parallel mode.
-.\" If no targets are
-.\" specified, then all targets are executed in parallel mode.
-.It Ic .PATH
-The sources are directories which are to be searched for files not
-found in the current directory.
-If no sources are specified, any previously specified directories are
-deleted.
-If the source is the special
-.Ic .DOTLAST
-target, then the current working
-directory is searched last.
-.It Ic .PATH. Ns Va suffix
-Like
-.Ic .PATH
-but applies only to files with a particular suffix.
-The suffix must have been previously declared with
-.Ic .SUFFIXES .
-.It Ic .PHONY
-Apply the
-.Ic .PHONY
-attribute to any specified sources.
-.It Ic .PRECIOUS
-Apply the
-.Ic .PRECIOUS
-attribute to any specified sources.
-If no sources are specified, the
-.Ic .PRECIOUS
-attribute is applied to every
-target in the file.
-.It Ic .SHELL
-Sets the shell that
-.Nm
-will use to execute commands.
-The sources are a set of
-.Ar field=value
-pairs.
-.Bl -tag -width hasErrCtls
-.It Ar name
-This is the minimal specification, used to select one of the builtin
-shell specs;
-.Ar sh ,
-.Ar ksh ,
-and
-.Ar csh .
-.It Ar path
-Specifies the path to the shell.
-.It Ar hasErrCtl
-Indicates whether the shell supports exit on error.
-.It Ar check
-The command to turn on error checking.
-.It Ar ignore
-The command to disable error checking.
-.It Ar echo
-The command to turn on echoing of commands executed.
-.It Ar quiet
-The command to turn off echoing of commands executed.
-.It Ar filter
-The output to filter after issuing the
-.Ar quiet
-command.
-It is typically identical to
-.Ar quiet .
-.It Ar errFlag
-The flag to pass the shell to enable error checking.
-.It Ar echoFlag
-The flag to pass the shell to enable command echoing.
-.It Ar newline
-The string literal to pass the shell that results in a single newline
-character when used outside of any quoting characters.
-.El
-Example:
-.Bd -literal
-\&.SHELL: name=ksh path=/bin/ksh hasErrCtl=true \e
- check="set \-e" ignore="set +e" \e
- echo="set \-v" quiet="set +v" filter="set +v" \e
- echoFlag=v errFlag=e newline="'\en'"
-.Ed
-.It Ic .SILENT
-Apply the
-.Ic .SILENT
-attribute to any specified sources.
-If no sources are specified, the
-.Ic .SILENT
-attribute is applied to every
-command in the file.
-.It Ic .STALE
-This target gets run when a dependency file contains stale entries, having
-.Va .ALLSRC
-set to the name of that dependency file.
-.It Ic .SUFFIXES
-Each source specifies a suffix to
-.Nm .
-If no sources are specified, any previously specified suffixes are deleted.
-It allows the creation of suffix-transformation rules.
-.Pp
-Example:
-.Bd -literal
-\&.SUFFIXES: .o
-\&.c.o:
- cc \-o ${.TARGET} \-c ${.IMPSRC}
-.Ed
-.El
-.Sh ENVIRONMENT
-.Nm
-uses the following environment variables, if they exist:
-.Ev MACHINE ,
-.Ev MACHINE_ARCH ,
-.Ev MAKE ,
-.Ev MAKEFLAGS ,
-.Ev MAKEOBJDIR ,
-.Ev MAKEOBJDIRPREFIX ,
-.Ev MAKESYSPATH ,
-.Ev PWD ,
-and
-.Ev TMPDIR .
-.Pp
-.Ev MAKEOBJDIRPREFIX
-and
-.Ev MAKEOBJDIR
-may only be set in the environment or on the command line to
-.Nm
-and not as makefile variables;
-see the description of
-.Ql Va .OBJDIR
-for more details.
-.Sh FILES
-.Bl -tag -width /usr/share/mk -compact
-.It .depend
-list of dependencies
-.It Makefile
-list of dependencies
-.It makefile
-list of dependencies
-.It sys.mk
-system makefile
-.It /usr/share/mk
-system makefile directory
-.El
-.Sh COMPATIBILITY
-The basic make syntax is compatible between different versions of make,
-however the special variables, variable modifiers and conditionals are not.
-.Pp
-The way that parallel makes are scheduled changed in
-.Nx 4.0
-so that .ORDER and .WAIT apply recursively to the dependent nodes.
-The algorithms used may change again in the future.
-.Pp
-The way that .for loop variables are substituted changed after
-.Nx 5.0
-so that they still appear to be variable expansions.
-In particular this stops them being treated as syntax, and removes some
-obscure problems using them in .if statements.
-.Sh SEE ALSO
-.Xr mkdep 1
-.Sh HISTORY
-A
-.Nm
-command appeared in
-.At v7 .
-This
-.Nm
-implementation is based on Adam De Boor's pmake program which was written
-for Sprite at Berkeley.
-It was designed to be a parallel distributed make running jobs on different
-machines using a daemon called
-.Dq customs .
-.Pp
-Historically the target/dependency
-.Dq FRC
-has been used to FoRCe rebuilding (since the target/dependency
-does not exist... unless someone creates an
-.Dq FRC
-file).
-.Sh BUGS
-The
-.Nm
-syntax is difficult to parse without actually acting of the data.
-For instance finding the end of a variable use should involve scanning each
-the modifiers using the correct terminator for each field.
-In many places
-.Nm
-just counts {} and () in order to find the end of a variable expansion.
-.Pp
-There is no way of escaping a space character in a filename.

+.Sh DESCRIPTION
+.Nm
+is a program designed to simplify the maintenance of other programs.
+Its input is a list of specifications as to the files upon which programs
+and other files depend.
+If no
+.Fl f Ar makefile
+makefile option is given,
+.Nm
+will try to open
+.Ql Pa makefile
+then
+.Ql Pa Makefile
+in order to find the specifications.
+If the file
+.Ql Pa .depend
+exists, it is read (see
+.Xr mkdep 1 ) .
+.Pp
+This manual page is intended as a reference document only.
+For a more thorough description of
+.Nm
+and makefiles, please refer to
+.%T "PMake \- A Tutorial" .
+.Pp
+.Nm
+will prepend the contents of the
+.Va MAKEFLAGS
+environment variable to the command line arguments before parsing them.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl B
+Try to be backwards compatible by executing a single shell per command and
+by executing the commands to make the sources of a dependency line in sequence.
+.It Fl C Ar directory
+Change to
+.Ar directory
+before reading the makefiles or doing anything else.
+If multiple
+.Fl C
+options are specified, each is interpreted relative to the previous one:
+.Fl C Pa / Fl C Pa etc
+is equivalent to
+.Fl C Pa /etc .
+.It Fl D Ar variable
+Define
+.Ar variable
+to be 1, in the global context.
+.It Fl d Ar [-]flags
+Turn on debugging, and specify which portions of
+.Nm
+are to print debugging information.
+Unless the flags are preceded by
+.Ql \-
+they are added to the
+.Va MAKEFLAGS
+environment variable and will be processed by any child make processes.
+By default, debugging information is printed to standard error,
+but this can be changed using the
+.Ar F
+debugging flag.
+The debugging output is always unbuffered; in addition, if debugging
+is enabled but debugging output is not directed to standard output,
+then the standard output is line buffered.
+.Ar Flags
+is one or more of the following:
+.Bl -tag -width Ds
+.It Ar A
+Print all possible debugging information;
+equivalent to specifying all of the debugging flags.
+.It Ar a
+Print debugging information about archive searching and caching.
+.It Ar C
+Print debugging information about current working directory.
+.It Ar c
+Print debugging information about conditional evaluation.
+.It Ar d
+Print debugging information about directory searching and caching.
+.It Ar e
+Print debugging information about failed commands and targets.
+.It Ar F Ns Oo Sy \&+ Oc Ns Ar filename
+Specify where debugging output is written.
+This must be the last flag, because it consumes the remainder of
+the argument.
+If the character immediately after the
+.Ql F
+flag is
+.Ql \&+ ,
+then the file will be opened in append mode;
+otherwise the file will be overwritten.
+If the file name is
+.Ql stdout
+or
+.Ql stderr
+then debugging output will be written to the
+standard output or standard error output file descriptors respectively
+(and the
+.Ql \&+
+option has no effect).
+Otherwise, the output will be written to the named file.
+If the file name ends
+.Ql .%d
+then the
+.Ql %d
+is replaced by the pid.
+.It Ar f
+Print debugging information about loop evaluation.
+.It Ar "g1"
+Print the input graph before making anything.
+.It Ar "g2"
+Print the input graph after making everything, or before exiting
+on error.
+.It Ar "g3"
+Print the input graph before exiting on error.
+.It Ar j
+Print debugging information about running multiple shells.
+.It Ar l
+Print commands in Makefiles regardless of whether or not they are prefixed by
+.Ql @
+or other "quiet" flags.
+Also known as "loud" behavior.
+.It Ar M
+Print debugging information about "meta" mode decisions about targets.
+.It Ar m
+Print debugging information about making targets, including modification
+dates.
+.It Ar n
+Don't delete the temporary command scripts created when running commands.
+These temporary scripts are created in the directory
+referred to by the
+.Ev TMPDIR
+environment variable, or in
+.Pa /tmp
+if
+.Ev TMPDIR
+is unset or set to the empty string.
+The temporary scripts are created by
+.Xr mkstemp 3 ,
+and have names of the form
+.Pa makeXXXXXX .
+.Em NOTE :
+This can create many files in
+.Ev TMPDIR
+or
+.Pa /tmp ,
+so use with care.
+.It Ar p
+Print debugging information about makefile parsing.
+.It Ar s
+Print debugging information about suffix-transformation rules.
+.It Ar t
+Print debugging information about target list maintenance.
+.It Ar V
+Force the
+.Fl V
+option to print raw values of variables, overriding the default behavior
+set via
+.Va .MAKE.EXPAND_VARIABLES .
+.It Ar v
+Print debugging information about variable assignment.
+.It Ar x
+Run shell commands with
+.Fl x
+so the actual commands are printed as they are executed.
+.El
+.It Fl e
+Specify that environment variables override macro assignments within
+makefiles.
+.It Fl f Ar makefile
+Specify a makefile to read instead of the default
+.Ql Pa makefile .
+If
+.Ar makefile
+is
+.Ql Fl ,
+standard input is read.
+Multiple makefiles may be specified, and are read in the order specified.
+.It Fl I Ar directory
+Specify a directory in which to search for makefiles and included makefiles.
+The system makefile directory (or directories, see the
+.Fl m
+option) is automatically included as part of this list.
+.It Fl i
+Ignore non-zero exit of shell commands in the makefile.
+Equivalent to specifying
+.Ql Fl
+before each command line in the makefile.
+.It Fl J Ar private
+This option should
+.Em not
+be specified by the user.
+.Pp
+When the
+.Ar j
+option is in use in a recursive build, this option is passed by a make
+to child makes to allow all the make processes in the build to
+cooperate to avoid overloading the system.
+.It Fl j Ar max_jobs
+Specify the maximum number of jobs that
+.Nm
+may have running at any one time.
+The value is saved in
+.Va .MAKE.JOBS .
+Turns compatibility mode off, unless the
+.Ar B
+flag is also specified.
+When compatibility mode is off, all commands associated with a
+target are executed in a single shell invocation as opposed to the
+traditional one shell invocation per line.
+This can break traditional scripts which change directories on each
+command invocation and then expect to start with a fresh environment
+on the next line.
+It is more efficient to correct the scripts rather than turn backwards
+compatibility on.
+.It Fl k
+Continue processing after errors are encountered, but only on those targets
+that do not depend on the target whose creation caused the error.
+.It Fl m Ar directory
+Specify a directory in which to search for sys.mk and makefiles included
+via the
+.Ao Ar file Ac Ns -style
+include statement.
+The
+.Fl m
+option can be used multiple times to form a search path.
+This path will override the default system include path: /usr/share/mk.
+Furthermore the system include path will be appended to the search path used
+for
+.Qo Ar file Qc Ns -style
+include statements (see the
+.Fl I
+option).
+.Pp
+If a file or directory name in the
+.Fl m
+argument (or the
+.Ev MAKESYSPATH
+environment variable) starts with the string
+.Qq \&.../
+then
+.Nm
+will search for the specified file or directory named in the remaining part
+of the argument string.
+The search starts with the current directory of
+the Makefile and then works upward towards the root of the file system.
+If the search is successful, then the resulting directory replaces the
+.Qq \&.../
+specification in the
+.Fl m
+argument.
+If used, this feature allows
+.Nm
+to easily search in the current source tree for customized sys.mk files
+(e.g., by using
+.Qq \&.../mk/sys.mk
+as an argument).
+.It Fl n
+Display the commands that would have been executed, but do not
+actually execute them unless the target depends on the .MAKE special
+source (see below).
+.It Fl N
+Display the commands which would have been executed, but do not
+actually execute any of them; useful for debugging top-level makefiles
+without descending into subdirectories.
+.It Fl q
+Do not execute any commands, but exit 0 if the specified targets are
+up-to-date and 1, otherwise.
+.It Fl r
+Do not use the built-in rules specified in the system makefile.
+.It Fl s
+Do not echo any commands as they are executed.
+Equivalent to specifying
+.Ql Ic @
+before each command line in the makefile.
+.It Fl T Ar tracefile
+When used with the
+.Fl j
+flag,
+append a trace record to
+.Ar tracefile
+for each job started and completed.
+.It Fl t
+Rather than re-building a target as specified in the makefile, create it
+or update its modification time to make it appear up-to-date.
+.It Fl V Ar variable
+Print the value of
+.Ar variable .
+Do not build any targets.
+Multiple instances of this option may be specified;
+the variables will be printed one per line,
+with a blank line for each null or undefined variable.
+The value printed is extracted from the global context after all
+makefiles have been read.
+By default, the raw variable contents (which may
+include additional unexpanded variable references) are shown.
+If
+.Ar variable
+contains a
+.Ql \&$
+then the value will be recursively expanded to its complete resultant
+text before printing.
+The expanded value will also be printed if
+.Va .MAKE.EXPAND_VARIABLES
+is set to true and
+the
+.Fl dV
+option has not been used to override it.
+Note that loop-local and target-local variables, as well as values
+taken temporarily by global variables during makefile processing, are
+not accessible via this option.
+The
+.Fl dv
+debug mode can be used to see these at the cost of generating
+substantial extraneous output.
+.It Fl v Ar variable
+Like
+.Fl V
+but the variable is always expanded to its complete value.
+.It Fl W
+Treat any warnings during makefile parsing as errors.
+.It Fl w
+Print entering and leaving directory messages, pre and post processing.
+.It Fl X
+Don't export variables passed on the command line to the environment
+individually.
+Variables passed on the command line are still exported
+via the
+.Va MAKEFLAGS
+environment variable.
+This option may be useful on systems which have a small limit on the
+size of command arguments.
+.It Ar variable=value
+Set the value of the variable
+.Ar variable
+to
+.Ar value .
+Normally, all values passed on the command line are also exported to
+sub-makes in the environment.
+The
+.Fl X
+flag disables this behavior.
+Variable assignments should follow options for POSIX compatibility
+but no ordering is enforced.
+.El
+.Pp
+There are seven different types of lines in a makefile: file dependency
+specifications, shell commands, variable assignments, include statements,
+conditional directives, for loops, and comments.
+.Pp
+In general, lines may be continued from one line to the next by ending
+them with a backslash
+.Pq Ql \e .
+The trailing newline character and initial whitespace on the following
+line are compressed into a single space.
+.Sh FILE DEPENDENCY SPECIFICATIONS
+Dependency lines consist of one or more targets, an operator, and zero
+or more sources.
+This creates a relationship where the targets
+.Dq depend
+on the sources
+and are usually created from them.
+The exact relationship between the target and the source is determined
+by the operator that separates them.
+The three operators are as follows:
+.Bl -tag -width flag
+.It Ic \&:
+A target is considered out-of-date if its modification time is less than
+those of any of its sources.
+Sources for a target accumulate over dependency lines when this operator
+is used.
+The target is removed if
+.Nm
+is interrupted.
+.It Ic \&!
+Targets are always re-created, but not until all sources have been
+examined and re-created as necessary.
+Sources for a target accumulate over dependency lines when this operator
+is used.
+The target is removed if
+.Nm
+is interrupted.
+.It Ic \&::
+If no sources are specified, the target is always re-created.
+Otherwise, a target is considered out-of-date if any of its sources has
+been modified more recently than the target.
+Sources for a target do not accumulate over dependency lines when this
+operator is used.
+The target will not be removed if
+.Nm
+is interrupted.
+.El
+.Pp
+Targets and sources may contain the shell wildcard values
+.Ql \&? ,
+.Ql * ,
+.Ql [] ,
+and
+.Ql {} .
+The values
+.Ql \&? ,
+.Ql * ,
+and
+.Ql []
+may only be used as part of the final
+component of the target or source, and must be used to describe existing
+files.
+The value
+.Ql {}
+need not necessarily be used to describe existing files.
+Expansion is in directory order, not alphabetically as done in the shell.
+.Sh SHELL COMMANDS
+Each target may have associated with it one or more lines of shell
+commands, normally
+used to create the target.
+Each of the lines in this script
+.Em must
+be preceded by a tab.
+(For historical reasons, spaces are not accepted.)
+While targets can appear in many dependency lines if desired, by
+default only one of these rules may be followed by a creation
+script.
+If the
+.Ql Ic \&::
+operator is used, however, all rules may include scripts and the
+scripts are executed in the order found.
+.Pp
+Each line is treated as a separate shell command, unless the end of
+line is escaped with a backslash
+.Pq Ql \e
+in which case that line and the next are combined.
+.\" The escaped newline is retained and passed to the shell, which
+.\" normally ignores it.
+.\" However, the tab at the beginning of the following line is removed.
+If the first characters of the command are any combination of
+.Ql Ic @ ,
+.Ql Ic + ,
+or
+.Ql Ic \- ,
+the command is treated specially.
+A
+.Ql Ic @
+causes the command not to be echoed before it is executed.
+A
+.Ql Ic +
+causes the command to be executed even when
+.Fl n
+is given.
+This is similar to the effect of the .MAKE special source,
+except that the effect can be limited to a single line of a script.
+A
+.Ql Ic \-
+in compatibility mode
+causes any non-zero exit status of the command line to be ignored.
+.Pp
+When
+.Nm
+is run in jobs mode with
+.Fl j Ar max_jobs ,
+the entire script for the target is fed to a
+single instance of the shell.
+In compatibility (non-jobs) mode, each command is run in a separate process.
+If the command contains any shell meta characters
+.Pq Ql #=|^(){};&<>*?[]:$`\e\en
+it will be passed to the shell; otherwise
+.Nm
+will attempt direct execution.
+If a line starts with
+.Ql Ic \-
+and the shell has ErrCtl enabled then failure of the command line
+will be ignored as in compatibility mode.
+Otherwise
+.Ql Ic \-
+affects the entire job;
+the script will stop at the first command line that fails,
+but the target will not be deemed to have failed.
+.Pp
+Makefiles should be written so that the mode of
+.Nm
+operation does not change their behavior.
+For example, any command which needs to use
+.Dq cd
+or
+.Dq chdir
+without potentially changing the directory for subsequent commands
+should be put in parentheses so it executes in a subshell.
+To force the use of one shell, escape the line breaks so as to make
+the whole script one command.
+For example:
+.Bd -literal -offset indent
+avoid-chdir-side-effects:
+ @echo Building $@ in `pwd`
+ @(cd ${.CURDIR} && ${MAKE} $@)
+ @echo Back in `pwd`
+
+ensure-one-shell-regardless-of-mode:
+ @echo Building $@ in `pwd`; \e
+ (cd ${.CURDIR} && ${MAKE} $@); \e
+ echo Back in `pwd`
+.Ed
+.Pp
+Since
+.Nm
+will
+.Xr chdir 2
+to
+.Ql Va .OBJDIR
+before executing any targets, each child process
+starts with that as its current working directory.
+.Sh VARIABLE ASSIGNMENTS
+Variables in make are much like variables in the shell, and, by tradition,
+consist of all upper-case letters.
+.Ss Variable assignment modifiers
+The five operators that can be used to assign values to variables are as
+follows:
+.Bl -tag -width Ds
+.It Ic \&=
+Assign the value to the variable.
+Any previous value is overridden.
+.It Ic \&+=
+Append the value to the current value of the variable.
+.It Ic \&?=
+Assign the value to the variable if it is not already defined.
+.It Ic \&:=
+Assign with expansion, i.e. expand the value before assigning it
+to the variable.
+Normally, expansion is not done until the variable is referenced.
+.Em NOTE :
+References to undefined variables are
+.Em not
+expanded.
+This can cause problems when variable modifiers are used.
+.It Ic \&!=
+Expand the value and pass it to the shell for execution and assign
+the result to the variable.
+Any newlines in the result are replaced with spaces.
+.El
+.Pp
+Any white-space before the assigned
+.Ar value
+is removed; if the value is being appended, a single space is inserted
+between the previous contents of the variable and the appended value.
+.Pp
+Variables are expanded by surrounding the variable name with either
+curly braces
+.Pq Ql {}
+or parentheses
+.Pq Ql ()
+and preceding it with
+a dollar sign
+.Pq Ql \&$ .
+If the variable name contains only a single letter, the surrounding
+braces or parentheses are not required.
+This shorter form is not recommended.
+.Pp
+If the variable name contains a dollar, then the name itself is expanded first.
+This allows almost arbitrary variable names, however names containing dollar,
+braces, parenthesis, or whitespace are really best avoided!
+.Pp
+If the result of expanding a variable contains a dollar sign
+.Pq Ql \&$
+the string is expanded again.
+.Pp
+Variable substitution occurs at three distinct times, depending on where
+the variable is being used.
+.Bl -enum
+.It
+Variables in dependency lines are expanded as the line is read.
+.It
+Variables in shell commands are expanded when the shell command is
+executed.
+.It
+.Dq .for
+loop index variables are expanded on each loop iteration.
+Note that other variables are not expanded inside loops so
+the following example code:
+.Bd -literal -offset indent
+
+.Dv .for i in 1 2 3
+a+= ${i}
+j= ${i}
+b+= ${j}
+.Dv .endfor
+
+all:
+ @echo ${a}
+ @echo ${b}
+
+.Ed
+will print:
+.Bd -literal -offset indent
+1 2 3
+3 3 3
+
+.Ed
+Because while ${a} contains
+.Dq 1 2 3
+after the loop is executed, ${b}
+contains
+.Dq ${j} ${j} ${j}
+which expands to
+.Dq 3 3 3
+since after the loop completes ${j} contains
+.Dq 3 .
+.El
+.Ss Variable classes
+The four different classes of variables (in order of increasing precedence)
+are:
+.Bl -tag -width Ds
+.It Environment variables
+Variables defined as part of
+.Nm Ns 's
+environment.
+.It Global variables
+Variables defined in the makefile or in included makefiles.
+.It Command line variables
+Variables defined as part of the command line.
+.It Local variables
+Variables that are defined specific to a certain target.
+.El
+.Pp
+Local variables are all built in and their values vary magically from
+target to target.
+It is not currently possible to define new local variables.
+The seven local variables are as follows:
+.Bl -tag -width ".ARCHIVE" -offset indent
+.It Va .ALLSRC
+The list of all sources for this target; also known as
+.Ql Va \&> .
+.It Va .ARCHIVE
+The name of the archive file; also known as
+.Ql Va \&! .
+.It Va .IMPSRC
+In suffix-transformation rules, the name/path of the source from which the
+target is to be transformed (the
+.Dq implied
+source); also known as
+.Ql Va \&< .
+It is not defined in explicit rules.
+.It Va .MEMBER
+The name of the archive member; also known as
+.Ql Va % .
+.It Va .OODATE
+The list of sources for this target that were deemed out-of-date; also
+known as
+.Ql Va \&? .
+.It Va .PREFIX
+The file prefix of the target, containing only the file portion, no suffix
+or preceding directory components; also known as
+.Ql Va * .
+The suffix must be one of the known suffixes declared with
+.Ic .SUFFIXES
+or it will not be recognized.
+.It Va .TARGET
+The name of the target; also known as
+.Ql Va @ .
+For compatibility with other makes this is an alias for
+.Ic .ARCHIVE
+in archive member rules.
+.El
+.Pp
+The shorter forms
+.Ql ( Va > ,
+.Ql Va \&! ,
+.Ql Va < ,
+.Ql Va % ,
+.Ql Va \&? ,
+.Ql Va * ,
+and
+.Ql Va @ )
+are permitted for backward
+compatibility with historical makefiles and legacy POSIX make and are
+not recommended.
+.Pp
+Variants of these variables with the punctuation followed immediately by
+.Ql D
+or
+.Ql F ,
+e.g.
+.Ql Va $(@D) ,
+are legacy forms equivalent to using the
+.Ql :H
+and
+.Ql :T
+modifiers.
+These forms are accepted for compatibility with
+.At V
+makefiles and POSIX but are not recommended.
+.Pp
+Four of the local variables may be used in sources on dependency lines
+because they expand to the proper value for each target on the line.
+These variables are
+.Ql Va .TARGET ,
+.Ql Va .PREFIX ,
+.Ql Va .ARCHIVE ,
+and
+.Ql Va .MEMBER .
+.Ss Additional built-in variables
+In addition,
+.Nm
+sets or knows about the following variables:
+.Bl -tag -width .MAKEOVERRIDES
+.It Va \&$
+A single dollar sign
+.Ql \&$ ,
+i.e.
+.Ql \&$$
+expands to a single dollar
+sign.
+.It Va .ALLTARGETS
+The list of all targets encountered in the Makefile.
+If evaluated during
+Makefile parsing, lists only those targets encountered thus far.
+.It Va .CURDIR
+A path to the directory where
+.Nm
+was executed.
+Refer to the description of
+.Ql Ev PWD
+for more details.
+.It Va .INCLUDEDFROMDIR
+The directory of the file this Makefile was included from.
+.It Va .INCLUDEDFROMFILE
+The filename of the file this Makefile was included from.
+.It Ev MAKE
+The name that
+.Nm
+was executed with
+.Pq Va argv[0] .
+For compatibility
+.Nm
+also sets
+.Va .MAKE
+with the same value.
+The preferred variable to use is the environment variable
+.Ev MAKE
+because it is more compatible with other versions of
+.Nm
+and cannot be confused with the special target with the same name.
+.It Va .MAKE.ALWAYS_PASS_JOB_QUEUE
+Tells
+.Nm
+whether to pass the descriptors of the job token queue
+even if the target is not tagged with
+.Ic .MAKE
+The default is
+.Ql Pa yes
+for backwards compatability with
+.Fx 9.0
+and earlier.
+.It Va .MAKE.DEPENDFILE
+Names the makefile (default
+.Ql Pa .depend )
+from which generated dependencies are read.
+.It Va .MAKE.EXPAND_VARIABLES
+A boolean that controls the default behavior of the
+.Fl V
+option.
+If true, variable values printed with
+.Fl V
+are fully expanded; if false, the raw variable contents (which may
+include additional unexpanded variable references) are shown.
+.It Va .MAKE.EXPORTED
+The list of variables exported by
+.Nm .
+.It Va .MAKE.JOBS
+The argument to the
+.Fl j
+option.
+.It Va .MAKE.JOB.PREFIX
+If
+.Nm
+is run with
+.Ar j
+then output for each target is prefixed with a token
+.Ql --- target ---
+the first part of which can be controlled via
+.Va .MAKE.JOB.PREFIX .
+If
+.Va .MAKE.JOB.PREFIX
+is empty, no token is printed.
+.br
+For example:
+.Li .MAKE.JOB.PREFIX=${.newline}---${.MAKE:T}[${.MAKE.PID}]
+would produce tokens like
+.Ql ---make[1234] target ---
+making it easier to track the degree of parallelism being achieved.
+.It Ev MAKEFLAGS
+The environment variable
+.Ql Ev MAKEFLAGS
+may contain anything that
+may be specified on
+.Nm Ns 's
+command line.
+Anything specified on
+.Nm Ns 's
+command line is appended to the
+.Ql Ev MAKEFLAGS
+variable which is then
+entered into the environment for all programs which
+.Nm
+executes.
+.It Va .MAKE.LEVEL
+The recursion depth of
+.Nm .
+The initial instance of
+.Nm
+will be 0, and an incremented value is put into the environment
+to be seen by the next generation.
+This allows tests like:
+.Li .if ${.MAKE.LEVEL} == 0
+to protect things which should only be evaluated in the initial instance of
+.Nm .
+.It Va .MAKE.MAKEFILE_PREFERENCE
+The ordered list of makefile names
+(default
+.Ql Pa makefile ,
+.Ql Pa Makefile )
+that
+.Nm
+will look for.
+.It Va .MAKE.MAKEFILES
+The list of makefiles read by
+.Nm ,
+which is useful for tracking dependencies.
+Each makefile is recorded only once, regardless of the number of times read.
+.It Va .MAKE.MODE
+Processed after reading all makefiles.
+Can affect the mode that
+.Nm
+runs in.
+It can contain a number of keywords:
+.Bl -hang -width missing-filemon=bf.
+.It Pa compat
+Like
+.Fl B ,
+puts
+.Nm
+into "compat" mode.
+.It Pa meta
+Puts
+.Nm
+into "meta" mode, where meta files are created for each target
+to capture the command run, the output generated and if
+.Xr filemon 4
+is available, the system calls which are of interest to
+.Nm .
+The captured output can be very useful when diagnosing errors.
+.It Pa curdirOk= Ar bf
+Normally
+.Nm
+will not create .meta files in
+.Ql Va .CURDIR .
+This can be overridden by setting
+.Va bf
+to a value which represents True.
+.It Pa missing-meta= Ar bf
+If
+.Va bf
+is True, then a missing .meta file makes the target out-of-date.
+.It Pa missing-filemon= Ar bf
+If
+.Va bf
+is True, then missing filemon data makes the target out-of-date.
+.It Pa nofilemon
+Do not use
+.Xr filemon 4 .
+.It Pa env
+For debugging, it can be useful to include the environment
+in the .meta file.
+.It Pa verbose
+If in "meta" mode, print a clue about the target being built.
+This is useful if the build is otherwise running silently.
+The message printed the value of:
+.Va .MAKE.META.PREFIX .
+.It Pa ignore-cmd
+Some makefiles have commands which are simply not stable.
+This keyword causes them to be ignored for
+determining whether a target is out of date in "meta" mode.
+See also
+.Ic .NOMETA_CMP .
+.It Pa silent= Ar bf
+If
+.Va bf
+is True, when a .meta file is created, mark the target
+.Ic .SILENT .
+.El
+.It Va .MAKE.META.BAILIWICK
+In "meta" mode, provides a list of prefixes which
+match the directories controlled by
+.Nm .
+If a file that was generated outside of
+.Va .OBJDIR
+but within said bailiwick is missing,
+the current target is considered out-of-date.
+.It Va .MAKE.META.CREATED
+In "meta" mode, this variable contains a list of all the meta files
+updated.
+If not empty, it can be used to trigger processing of
+.Va .MAKE.META.FILES .
+.It Va .MAKE.META.FILES
+In "meta" mode, this variable contains a list of all the meta files
+used (updated or not).
+This list can be used to process the meta files to extract dependency
+information.
+.It Va .MAKE.META.IGNORE_PATHS
+Provides a list of path prefixes that should be ignored;
+because the contents are expected to change over time.
+The default list includes:
+.Ql Pa /dev /etc /proc /tmp /var/run /var/tmp
+.It Va .MAKE.META.IGNORE_PATTERNS
+Provides a list of patterns to match against pathnames.
+Ignore any that match.
+.It Va .MAKE.META.IGNORE_FILTER
+Provides a list of variable modifiers to apply to each pathname.
+Ignore if the expansion is an empty string.
+.It Va .MAKE.META.PREFIX
+Defines the message printed for each meta file updated in "meta verbose" mode.
+The default value is:
+.Dl Building ${.TARGET:H:tA}/${.TARGET:T}
+.It Va .MAKEOVERRIDES
+This variable is used to record the names of variables assigned to
+on the command line, so that they may be exported as part of
+.Ql Ev MAKEFLAGS .
+This behavior can be disabled by assigning an empty value to
+.Ql Va .MAKEOVERRIDES
+within a makefile.
+Extra variables can be exported from a makefile
+by appending their names to
+.Ql Va .MAKEOVERRIDES .
+.Ql Ev MAKEFLAGS
+is re-exported whenever
+.Ql Va .MAKEOVERRIDES
+is modified.
+.It Va .MAKE.PATH_FILEMON
+If
+.Nm
+was built with
+.Xr filemon 4
+support, this is set to the path of the device node.
+This allows makefiles to test for this support.
+.It Va .MAKE.PID
+The process-id of
+.Nm .
+.It Va .MAKE.PPID
+The parent process-id of
+.Nm .
+.It Va .MAKE.SAVE_DOLLARS
+value should be a boolean that controls whether
+.Ql $$
+are preserved when doing
+.Ql :=
+assignments.
+The default is false, for backwards compatibility.
+Set to true for compatability with other makes.
+If set to false,
+.Ql $$
+becomes
+.Ql $
+per normal evaluation rules.
+.It Va MAKE_PRINT_VAR_ON_ERROR
+When
+.Nm
+stops due to an error, it sets
+.Ql Va .ERROR_TARGET
+to the name of the target that failed,
+.Ql Va .ERROR_CMD
+to the commands of the failed target,
+and in "meta" mode, it also sets
+.Ql Va .ERROR_CWD
+to the
+.Xr getcwd 3 ,
+and
+.Ql Va .ERROR_META_FILE
+to the path of the meta file (if any) describing the failed target.
+It then prints its name and the value of
+.Ql Va .CURDIR
+as well as the value of any variables named in
+.Ql Va MAKE_PRINT_VAR_ON_ERROR .
+.It Va .newline
+This variable is simply assigned a newline character as its value.
+This allows expansions using the
+.Cm \&:@
+modifier to put a newline between
+iterations of the loop rather than a space.
+For example, the printing of
+.Ql Va MAKE_PRINT_VAR_ON_ERROR
+could be done as ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@}.
+.It Va .OBJDIR
+A path to the directory where the targets are built.
+Its value is determined by trying to
+.Xr chdir 2
+to the following directories in order and using the first match:
+.Bl -enum
+.It
+.Ev ${MAKEOBJDIRPREFIX}${.CURDIR}
+.Pp
+(Only if
+.Ql Ev MAKEOBJDIRPREFIX
+is set in the environment or on the command line.)
+.It
+.Ev ${MAKEOBJDIR}
+.Pp
+(Only if
+.Ql Ev MAKEOBJDIR
+is set in the environment or on the command line.)
+.It
+.Ev ${.CURDIR} Ns Pa /obj. Ns Ev ${MACHINE}
+.It
+.Ev ${.CURDIR} Ns Pa /obj
+.It
+.Pa /usr/obj/ Ns Ev ${.CURDIR}
+.It
+.Ev ${.CURDIR}
+.El
+.Pp
+Variable expansion is performed on the value before it's used,
+so expressions such as
+.Dl ${.CURDIR:S,^/usr/src,/var/obj,}
+may be used.
+This is especially useful with
+.Ql Ev MAKEOBJDIR .
+.Pp
+.Ql Va .OBJDIR
+may be modified in the makefile via the special target
+.Ql Ic .OBJDIR .
+In all cases,
+.Nm
+will
+.Xr chdir 2
+to the specified directory if it exists, and set
+.Ql Va .OBJDIR
+and
+.Ql Ev PWD
+to that directory before executing any targets.
+.
+.It Va .PARSEDIR
+A path to the directory of the current
+.Ql Pa Makefile
+being parsed.
+.It Va .PARSEFILE
+The basename of the current
+.Ql Pa Makefile
+being parsed.
+This variable and
+.Ql Va .PARSEDIR
+are both set only while the
+.Ql Pa Makefiles
+are being parsed.
+If you want to retain their current values, assign them to a variable
+using assignment with expansion:
+.Pq Ql Cm \&:= .
+.It Va .PATH
+A variable that represents the list of directories that
+.Nm
+will search for files.
+The search list should be updated using the target
+.Ql Va .PATH
+rather than the variable.
+.It Ev PWD
+Alternate path to the current directory.
+.Nm
+normally sets
+.Ql Va .CURDIR
+to the canonical path given by
+.Xr getcwd 3 .
+However, if the environment variable
+.Ql Ev PWD
+is set and gives a path to the current directory, then
+.Nm
+sets
+.Ql Va .CURDIR
+to the value of
+.Ql Ev PWD
+instead.
+This behavior is disabled if
+.Ql Ev MAKEOBJDIRPREFIX
+is set or
+.Ql Ev MAKEOBJDIR
+contains a variable transform.
+.Ql Ev PWD
+is set to the value of
+.Ql Va .OBJDIR
+for all programs which
+.Nm
+executes.
+.It Ev .TARGETS
+The list of targets explicitly specified on the command line, if any.
+.It Ev VPATH
+Colon-separated
+.Pq Dq \&:
+lists of directories that
+.Nm
+will search for files.
+The variable is supported for compatibility with old make programs only,
+use
+.Ql Va .PATH
+instead.
+.El
+.Ss Variable modifiers
+Variable expansion may be modified to select or modify each word of the
+variable (where a
+.Dq word
+is white-space delimited sequence of characters).
+The general format of a variable expansion is as follows:
+.Pp
+.Dl ${variable[:modifier[:...]]}
+.Pp
+Each modifier begins with a colon,
+which may be escaped with a backslash
+.Pq Ql \e .
+.Pp
+A set of modifiers can be specified via a variable, as follows:
+.Pp
+.Dl modifier_variable=modifier[:...]
+.Dl ${variable:${modifier_variable}[:...]}
+.Pp
+In this case the first modifier in the modifier_variable does not
+start with a colon, since that must appear in the referencing
+variable.
+If any of the modifiers in the modifier_variable contain a dollar sign
+.Pq Ql $ ,
+these must be doubled to avoid early expansion.
+.Pp
+The supported modifiers are:
+.Bl -tag -width EEE
+.It Cm \&:E
+Replaces each word in the variable with its suffix.
+.It Cm \&:H
+Replaces each word in the variable with everything but the last component.
+.It Cm \&:M Ns Ar pattern
+Select only those words that match
+.Ar pattern .
+The standard shell wildcard characters
+.Pf ( Ql * ,
+.Ql \&? ,
+and
+.Ql Oo Oc )
+may
+be used.
+The wildcard characters may be escaped with a backslash
+.Pq Ql \e .
+As a consequence of the way values are split into words, matched,
+and then joined, a construct like
+.Dl ${VAR:M*}
+will normalize the inter-word spacing, removing all leading and
+trailing space, and converting multiple consecutive spaces
+to single spaces.
+.
+.It Cm \&:N Ns Ar pattern
+This is identical to
+.Ql Cm \&:M ,
+but selects all words which do not match
+.Ar pattern .
+.It Cm \&:O
+Order every word in variable alphabetically.
+To sort words in
+reverse order use the
+.Ql Cm \&:O:[-1..1]
+combination of modifiers.
+.It Cm \&:Ox
+Randomize words in variable.
+The results will be different each time you are referring to the
+modified variable; use the assignment with expansion
+.Pq Ql Cm \&:=
+to prevent such behavior.
+For example,
+.Bd -literal -offset indent
+LIST= uno due tre quattro
+RANDOM_LIST= ${LIST:Ox}
+STATIC_RANDOM_LIST:= ${LIST:Ox}
+
+all:
+ @echo "${RANDOM_LIST}"
+ @echo "${RANDOM_LIST}"
+ @echo "${STATIC_RANDOM_LIST}"
+ @echo "${STATIC_RANDOM_LIST}"
+.Ed
+may produce output similar to:
+.Bd -literal -offset indent
+quattro due tre uno
+tre due quattro uno
+due uno quattro tre
+due uno quattro tre
+.Ed
+.It Cm \&:Q
+Quotes every shell meta-character in the variable, so that it can be passed
+safely through recursive invocations of
+.Nm .
+.It Cm \&:R
+Replaces each word in the variable with everything but its suffix.
+.It Cm \&:range[=count]
+The value is an integer sequence representing the words of the original
+value, or the supplied
+.Va count .
+.It Cm \&:gmtime[=utc]
+The value is a format string for
+.Xr strftime 3 ,
+using
+.Xr gmtime 3 .
+If a
+.Va utc
+value is not provided or is 0, the current time is used.
+.It Cm \&:hash
+Compute a 32-bit hash of the value and encode it as hex digits.
+.It Cm \&:localtime[=utc]
+The value is a format string for
+.Xr strftime 3 ,
+using
+.Xr localtime 3 .
+If a
+.Va utc
+value is not provided or is 0, the current time is used.
+.It Cm \&:tA
+Attempt to convert variable to an absolute path using
+.Xr realpath 3 ,
+if that fails, the value is unchanged.
+.It Cm \&:tl
+Converts variable to lower-case letters.
+.It Cm \&:ts Ns Ar c
+Words in the variable are normally separated by a space on expansion.
+This modifier sets the separator to the character
+.Ar c .
+If
+.Ar c
+is omitted, then no separator is used.
+The common escapes (including octal numeric codes), work as expected.
+.It Cm \&:tu
+Converts variable to upper-case letters.
+.It Cm \&:tW
+Causes the value to be treated as a single word
+(possibly containing embedded white space).
+See also
+.Ql Cm \&:[*] .
+.It Cm \&:tw
+Causes the value to be treated as a sequence of
+words delimited by white space.
+See also

+The

+modifier is just like the
+.Cm \&:S
+modifier except that the old and new strings, instead of being
+simple strings, are an extended regular expression (see
+.Xr regex 3 )
+string
+.Ar pattern
+and an
+.Xr ed 1 Ns \-style
+string
+.Ar replacement .
+Normally, the first occurrence of the pattern
+.Ar pattern
+in each word of the value is substituted with
+.Ar replacement .
+The
+.Ql 1
+modifier causes the substitution to apply to at most one word; the
+.Ql g
+modifier causes the substitution to apply to as many instances of the
+search pattern
+.Ar pattern
+as occur in the word or words it is found in; the
+.Ql W
+modifier causes the value to be treated as a single word
+(possibly containing embedded white space).
+Note that
+.Ql 1
+and
+.Ql g
+are orthogonal; the former specifies whether multiple words are
+potentially affected, the latter whether multiple substitutions can
+potentially occur within each affected word.
+.Pp
+As for the
+.Cm \&:S
+modifier, the
+.Ar pattern
+and
+.Ar replacement
+are subjected to variable expansion before being parsed as
+regular expressions.
+.It Cm \&:T
+Replaces each word in the variable with its last component.

+If the variable name (not its value), when parsed as a .if conditional

+otherwise return the
+.Ar false_string .
+Since the variable name is used as the expression, \&:\&? must be the
+first modifier after the variable name itself - which will, of course,
+usually contain variable expansions.
+A common error is trying to use expressions like
+.Dl ${NUMBERS:M42:?match:no}
+which actually tests defined(NUMBERS),
+to determine is any words match "42" you need to use something like:
+.Dl ${"${NUMBERS:M42}" != \&"\&":?match:no} .
+.It Ar :old_string=new_string
+This is the
+.At V
+style variable substitution.
+It must be the last modifier specified.
+If
+.Ar old_string
+or
+.Ar new_string
+do not contain the pattern matching character
+.Ar %
+then it is assumed that they are
+anchored at the end of each word, so only suffixes or entire
+words may be replaced.
+Otherwise
+.Ar %
+is the substring of
+.Ar old_string
+to be replaced in
+.Ar new_string .

+This is the loop expansion mechanism from the OSF Development

+Assign
+.Ar temp
+to each word in the variable and evaluate

+The ODE convention is that
+.Ar temp
+should start and end with a period.
+For example.
+.Dl ${LINKS:@.LINK.@${LN} ${TARGET} ${.LINK.}@}
+.Pp
+However a single character variable is often more readable:
+.Dl ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@}
+.It Cm \&:_[=var]
+Save the current variable value in
+.Ql $_
+or the named

+M_cmpv.units = 1 1000 1000000
+M_cmpv = S,., ,g:_:range:@i at + $${_:[-$$i]} \&\\

+
+.Dv .if ${VERSION:${M_cmpv}} < ${3.1.12:L:${M_cmpv}}
+
+.Ed
+Here
+.Ql $_
+is used to save the result of the
+.Ql :S
+modifier which is later referenced using the index values from
+.Ql :range .
+.It Cm \&:U Ns Ar newval
+If the variable is undefined
+.Ar newval
+is the value.
+If the variable is defined, the existing value is returned.
+This is another ODE make feature.
+It is handy for setting per-target CFLAGS for instance:
+.Dl ${_${.TARGET:T}_CFLAGS:U${DEF_CFLAGS}}
+If a value is only required if the variable is undefined, use:
+.Dl ${VAR:D:Unewval}
+.It Cm \&:D Ns Ar newval
+If the variable is defined
+.Ar newval
+is the value.
+.It Cm \&:L
+The name of the variable is the value.
+.It Cm \&:P
+The path of the node which has the same name as the variable
+is the value.
+If no such node exists or its path is null, then the
+name of the variable is used.
+In order for this modifier to work, the name (node) must at least have
+appeared on the rhs of a dependency.
+.Sm off
+.It Cm \&:\&! Ar cmd Cm \&!
+.Sm on
+The output of running
+.Ar cmd
+is the value.
+.It Cm \&:sh
+If the variable is non-empty it is run as a command and the output
+becomes the new value.
+.It Cm \&::= Ns Ar str
+The variable is assigned the value
+.Ar str
+after substitution.
+This modifier and its variations are useful in
+obscure situations such as wanting to set a variable when shell commands
+are being parsed.
+These assignment modifiers always expand to
+nothing, so if appearing in a rule line by themselves should be
+preceded with something to keep
+.Nm
+happy.
+.Pp
+The
+.Ql Cm \&::
+helps avoid false matches with the
+.At V
+style
+.Cm \&:=
+modifier and since substitution always occurs the
+.Cm \&::=
+form is vaguely appropriate.
+.It Cm \&::?= Ns Ar str
+As for
+.Cm \&::=
+but only if the variable does not already have a value.
+.It Cm \&::+= Ns Ar str
+Append
+.Ar str
+to the variable.
+.It Cm \&::!= Ns Ar cmd
+Assign the output of
+.Ar cmd
+to the variable.
+.It Cm \&:\&[ Ns Ar range Ns Cm \&]
+Selects one or more words from the value,
+or performs other operations related to the way in which the
+value is divided into words.
+.Pp
+Ordinarily, a value is treated as a sequence of words
+delimited by white space.
+Some modifiers suppress this behavior,
+causing a value to be treated as a single word
+(possibly containing embedded white space).
+An empty value, or a value that consists entirely of white-space,
+is treated as a single word.
+For the purposes of the
+.Ql Cm \&:[]
+modifier, the words are indexed both forwards using positive integers
+(where index 1 represents the first word),
+and backwards using negative integers
+(where index \-1 represents the last word).
+.Pp
+The
+.Ar range
+is subjected to variable expansion, and the expanded result is
+then interpreted as follows:
+.Bl -tag -width index
+.\" :[n]
+.It Ar index
+Selects a single word from the value.
+.\" :[start..end]
+.It Ar start Ns Cm \&.. Ns Ar end
+Selects all words from
+.Ar start
+to
+.Ar end ,
+inclusive.
+For example,
+.Ql Cm \&:[2..-1]
+selects all words from the second word to the last word.
+If
+.Ar start
+is greater than
+.Ar end ,
+then the words are output in reverse order.
+For example,
+.Ql Cm \&:[-1..1]
+selects all the words from last to first.
+.\" :[*]
+.It Cm \&*
+Causes subsequent modifiers to treat the value as a single word
+(possibly containing embedded white space).
+Analogous to the effect of

+.Sh INCLUDE STATEMENTS, CONDITIONALS AND FOR LOOPS
+Makefile inclusion, conditional structures and for loops reminiscent
+of the C programming language are provided in

+All such structures are identified by a line beginning with a single
+dot
+.Pq Ql \&.
+character.
+Files are included with either
+.Cm \&.include Aq Ar file
+or
+.Cm \&.include Pf \*q Ar file Ns \*q .
+Variables between the angle brackets or double quotes are expanded
+to form the file name.
+If angle brackets are used, the included makefile is expected to be in
+the system makefile directory.
+If double quotes are used, the including makefile's directory and any
+directories specified using the
+.Fl I
+option are searched before the system
+makefile directory.
+For compatibility with other versions of
+.Nm
+.Ql include file ...
+is also accepted.
+.Pp
+If the include statement is written as
+.Cm .-include
+or as
+.Cm .sinclude
+then errors locating and/or opening include files are ignored.
+.Pp
+If the include statement is written as
+.Cm .dinclude
+not only are errors locating and/or opening include files ignored,
+but stale dependencies within the included file will be ignored
+just like
+.Va .MAKE.DEPENDFILE .
+.Pp
+Conditional expressions are also preceded by a single dot as the first
+character of a line.
+The possible conditionals are as follows:
+.Bl -tag -width Ds
+.It Ic .error Ar message
+The message is printed along with the name of the makefile and line number,
+then
+.Nm
+will exit.
+.It Ic .export Ar variable ...
+Export the specified global variable.
+If no variable list is provided, all globals are exported
+except for internal variables (those that start with
+.Ql \&. ) .
+This is not affected by the
+.Fl X
+flag, so should be used with caution.
+For compatibility with other
+.Nm
+programs
+.Ql export variable=value
+is also accepted.
+.Pp
+Appending a variable name to
+.Va .MAKE.EXPORTED
+is equivalent to exporting a variable.
+.It Ic .export-env Ar variable ...
+The same as
+.Ql .export ,
+except that the variable is not appended to

+This allows exporting a value to the environment which is different from that
+used by

+.It Ic .export-literal Ar variable ...
+The same as

+except that variables in the value are not expanded.
+.It Ic .info Ar message
+The message is printed along with the name of the makefile and line number.
+.It Ic .undef Ar variable
+Un-define the specified global variable.
+Only global variables may be un-defined.
+.It Ic .unexport Ar variable ...
+The opposite of
+.Ql .export .
+The specified global
+.Va variable
+will be removed from
+.Va .MAKE.EXPORTED .
+If no variable list is provided, all globals are unexported,
+and
+.Va .MAKE.EXPORTED
+deleted.
+.It Ic .unexport-env
+Unexport all globals previously exported and
+clear the environment inherited from the parent.
+This operation will cause a memory leak of the original environment,
+so should be used sparingly.
+Testing for
+.Va .MAKE.LEVEL
+being 0, would make sense.
+Also note that any variables which originated in the parent environment
+should be explicitly preserved if desired.
+For example:
+.Bd -literal -offset indent
+.Li .if ${.MAKE.LEVEL} == 0
+PATH := ${PATH}
+.Li .unexport-env
+.Li .export PATH
+.Li .endif
+.Pp
+.Ed
+Would result in an environment containing only

+which is the minimal useful environment.
+Actually

+.Pp
+The value of

+explicitly, see
+.Va .MAIN )
+before the line containing the conditional.
+.It Ic empty
+Takes a variable, with possible modifiers, and evaluates to true if
+the expansion of the variable would result in an empty string.
+.It Ic exists
+Takes a file name as an argument and evaluates to true if the file exists.
+The file is searched for on the system search path (see
+.Va .PATH ) .
+.It Ic target
+Takes a target name as an argument and evaluates to true if the target
+has been defined.
+.It Ic commands
+Takes a target name as an argument and evaluates to true if the target
+has been defined and has commands associated with it.
+.El
+.Pp
+.Ar Expression
+may also be an arithmetic or string comparison.
+Variable expansion is
+performed on both sides of the comparison, after which the integral
+values are compared.
+A value is interpreted as hexadecimal if it is
+preceded by 0x, otherwise it is decimal; octal numbers are not supported.
+The standard C relational operators are all supported.
+If after
+variable expansion, either the left or right hand side of a
+.Ql Ic ==
+or
+.Ql Ic "!="
+operator is not an integral value, then
+string comparison is performed between the expanded
+variables.
+If no relational operator is given, it is assumed that the expanded
+variable is being compared against 0 or an empty string in the case
+of a string comparison.
+.Pp
+When
+.Nm
+is evaluating one of these conditional expressions, and it encounters
+a (white-space separated) word it doesn't recognize, either the
+.Dq make
+or
+.Dq defined
+expression is applied to it, depending on the form of the conditional.
+If the form is
+.Ql Ic .ifdef ,
+.Ql Ic .ifndef ,
+or
+.Ql Ic .if
+the
+.Dq defined
+expression is applied.
+Similarly, if the form is
+.Ql Ic .ifmake
+or
+.Ql Ic .ifnmake , the
+.Dq make
+expression is applied.
+.Pp
+If the conditional evaluates to true the parsing of the makefile continues
+as before.
+If it evaluates to false, the following lines are skipped.
+In both cases this continues until a
+.Ql Ic .else
+or
+.Ql Ic .endif
+is found.
+.Pp
+For loops are typically used to apply a set of rules to a list of files.
+The syntax of a for loop is:
+.Pp
+.Bl -tag -compact -width Ds
+.It Ic \&.for Ar variable Oo Ar variable ... Oc Ic in Ar expression
+.It Aq make-rules
+.It Ic \&.endfor
+.El
+.Pp
+After the for
+.Ic expression
+is evaluated, it is split into words.
+On each iteration of the loop, one word is taken and assigned to each
+.Ic variable ,
+in order, and these
+.Ic variables
+are substituted into the
+.Ic make-rules
+inside the body of the for loop.
+The number of words must come out even; that is, if there are three
+iteration variables, the number of words provided must be a multiple
+of three.

+The sources are a set of
+.Ar field=value
+pairs.
+.Bl -tag -width hasErrCtls
+.It Ar name
+This is the minimal specification, used to select one of the built-in
+shell specs;
+.Ar sh ,
+.Ar ksh ,
+and
+.Ar csh .
+.It Ar path
+Specifies the path to the shell.
+.It Ar hasErrCtl
+Indicates whether the shell supports exit on error.
+.It Ar check
+The command to turn on error checking.
+.It Ar ignore
+The command to disable error checking.
+.It Ar echo
+The command to turn on echoing of commands executed.
+.It Ar quiet
+The command to turn off echoing of commands executed.
+.It Ar filter
+The output to filter after issuing the
+.Ar quiet
+command.
+It is typically identical to
+.Ar quiet .
+.It Ar errFlag
+The flag to pass the shell to enable error checking.
+.It Ar echoFlag
+The flag to pass the shell to enable command echoing.
+.It Ar newline
+The string literal to pass the shell that results in a single newline
+character when used outside of any quoting characters.

+.It Ic .STALE
+This target gets run when a dependency file contains stale entries, having
+.Va .ALLSRC
+set to the name of that dependency file.
+.It Ic .SUFFIXES
+Each source specifies a suffix to
+.Nm .
+If no sources are specified, any previously specified suffixes are deleted.
+It allows the creation of suffix-transformation rules.

+.Ev MAKEOBJDIRPREFIX ,
+.Ev MAKESYSPATH ,
+.Ev PWD ,
+and
+.Ev TMPDIR .
+.Pp
+.Ev MAKEOBJDIRPREFIX
+and
+.Ev MAKEOBJDIR
+may only be set in the environment or on the command line to
+.Nm

+.El
+.Sh COMPATIBILITY
+The basic make syntax is compatible between different versions of make;
+however the special variables, variable modifiers and conditionals are not.
+.Ss Older versions
+An incomplete list of changes in older versions of
+.Nm :
+.Pp
+The way that .for loop variables are substituted changed after
+.Nx 5.0
+so that they still appear to be variable expansions.
+In particular this stops them being treated as syntax, and removes some
+obscure problems using them in .if statements.
+.Pp
+The way that parallel makes are scheduled changed in
+.Nx 4.0
+so that .ORDER and .WAIT apply recursively to the dependent nodes.
+The algorithms used may change again in the future.
+.Ss Other make dialects
+Other make dialects (GNU make, SVR4 make, POSIX make, etc.) do not
+support most of the features of
+.Nm
+as described in this manual.
+Most notably:
+.Bl -bullet -offset indent
+.It
+The
+.Ic .WAIT
+and
+.Ic .ORDER
+declarations and most functionality pertaining to parallelization.
+(GNU make supports parallelization but lacks these features needed to
+control it effectively.)
+.It
+Directives, including for loops and conditionals and most of the
+forms of include files.
+(GNU make has its own incompatible and less powerful syntax for
+conditionals.)
+.It
+All built-in variables that begin with a dot.
+.It
+Most of the special sources and targets that begin with a dot,
+with the notable exception of
+.Ic .PHONY ,
+.Ic .PRECIOUS ,
+and
+.Ic .SUFFIXES .
+.It
+Variable modifiers, except for the
+.Dl :old=new
+string substitution, which does not portably support globbing with
+.Ql %
+and historically only works on declared suffixes.
+.It
+The
+.Ic $>
+variable even in its short form; most makes support this functionality
+but its name varies.
+.El
+.Pp
+Some features are somewhat more portable, such as assignment with
+.Ic += ,
+.Ic ?= ,
+and
+.Ic != .
+The
+.Ic .PATH
+functionality is based on an older feature
+.Ic VPATH
+found in GNU make and many versions of SVR4 make; however,
+historically its behavior is too ill-defined (and too buggy) to rely
+upon.
+.Pp
+The
+.Ic $@
+and
+.Ic $<
+variables are more or less universally portable, as is the
+.Ic $(MAKE)
+variable.
+Basic use of suffix rules (for files only in the current directory,
+not trying to chain transformations together, etc.) is also reasonably
+portable.
+.Sh SEE ALSO
+.Xr mkdep 1
+.Sh HISTORY
+A
+.Nm
+command appeared in
+.At v7 .
+This
+.Nm
+implementation is based on Adam De Boor's pmake program which was written
+for Sprite at Berkeley.
+It was designed to be a parallel distributed make running jobs on different
+machines using a daemon called
+.Dq customs .
+.Pp
+Historically the target/dependency
+.Dq FRC
+has been used to FoRCe rebuilding (since the target/dependency
+does not exist... unless someone creates an
+.Dq FRC
+file).
+.Sh BUGS
+The
+.Nm
+syntax is difficult to parse without actually acting of the data.
+For instance finding the end of a variable use should involve scanning each
+the modifiers using the correct terminator for each field.
+In many places
+.Nm
+just counts {} and () in order to find the end of a variable expansion.
+.Pp
+There is no way of escaping a space character in a filename.

-2014-02-09 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * options.mk: cleanup and simplify semanitcs
- NO_* dominates all, if both WITH_* and WITHOUT_*
- are defined then result is DOMINATE_* which defaults to "no".
- Ie. WITHOUT_ normally wins.
-
-2013-12-12 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * install-mk (MK_VERSION): bump version
- * meta2deps.py: convert to print function for python3 compat.

- otherwise we get bytes instead of strings.
-
-2013-10-10 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * install-mk (MK_VERSION): bump version
-
- * dirdeps.mk: when TARGET_SPEC_VARS is more than just MACHINE
- apply the same filtering (M_dep_qual_fixes) when setting _machines
- as _build_dirs.
- Also fix the filtering of Makefile.depend files - for reporting
- what we are looking for (M_dep_qual_fixes can get confused by
- Makefile.depend)
- Add some more debug info.
-
-2013-09-04 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * gendirdeps.mk (_objtops): fix typo also
- while processing M2D_OBJROOTS to gather qualdir_list
- qualify $ql with loop iterator to ensure correct results.

- for when $MACHINE isn't enough for objdir distinction.
- Bring meta2deps.sh closer to par with meta2deps.py.
-
-2013-04-18 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * meta.stage.mk: set INSTALL to STAGE_INSTALL when making 'all'
- also if the target 'beforeinstall' exists, make it depend on
- .dirdep (incase it uses STAGE_INSTALL).
-
-2013-04-17 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * install-mk (MK_VERSION): 20130401 ;-)
- * meta.stage.mk (STAGE_INSTALL_SH): add stage-install.sh as

- * meta.stage.mk (LN_CP_SCRIPT): Add LnCp to do the ln||cp dance
- consistently.
- * dirdeps.mk: better describe the dance in sys.mk for TARGET_SPEC.
-
-2013-03-18 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * gendirdeps.mk: revert the dance around .MAKE.DEPENDFILE_DEFAULT
- it is simpler to just not update when say building for "host"
- (where we know we apply filters to DIRDEPS), and using a
- non-machine qualified dependfile.
-
-2013-03-16 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * dirdeps.mk: improve DIRDEPS filtering by allowing DEP_SKIP_DIR
- and DEP_DIRDEPS_FILTER to vary by DEP_MACHINE and DEP_TARGET_SPEC
- * gendirdeps.mk: ensure _objroot has trailing / if it needs it.
- * meta2deps.py: if machine is "host", then also trim
- self.host_target from any OBJROOTS.
-
-
-2013-03-11 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * gendirdeps.mk: if .MAKE.DEPENDFILE_DEFAULT is not machine
- qualified but _DEPENDFILE is, and .MAKE.DEPENDFILE_DEFAULT exists
- but _DEPENDFILE does not, compare the new _DEPENDFILE against
- .MAKE.DEPENDFILE_DEFAULT and discard if the same.
-
-2013-03-08 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * meta.stage.mk: use STAGE_TARGETS to control .ORDER
- and hook to all: via staging:
-
-2013-03-07 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * sys.dependfile.mk (.MAKE.DEPENDFILE_DEFAULT):
- use a separate variable for the default .MAKE.DEPENDFILE value
- so that it can be controlled independently of
- .MAKE.DEPENDFILE_PREFERENCE
-
- * meta.stage.mk: throw error if cp fails etc.
- Stage*() return early if passed no args.
- .ORDER stage_*

- * import latest dirdeps.mk, gendirdeps.mk and meta2deps.py
- from Juniper.
- o dirdeps.mk now fully supports TARGET_SPEC consisting of more
- than just MACHINE.
- o no longer use DEP_MACHINE from Makefile.depend* so remove it.
-
-2013-01-23 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * install-mk (MK_VERSION): bump version to 20130123
- * meta.stage.mk: add stage_links (hard links).
- if doing hard links, we add dest to link as well.

- these are typically specified as absolute paths.
- Add -m "mode" flag to StageFiles and StageAs.
-
-2012-11-11 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * install-mk (MK_VERSION): bump version to 20121111
- * autoconf.mk: avoid meta mode seeing changed commands for config.status
- * meta.autodep.mk: pass resolved MAKESYSPATH to gendirdeps
- in case we were found via .../mk
- * sys.clean-env.mk: move it from examples, we and others use it
- "as is".
- * FILES: add srctop.mk and options.mk
- * own.mk: convert to using options.mk
- which is modeled after FreeBSD's handling of MK_*
- but more flexible.
- This allows MK_* for boolean knobs to not be confused
- with MK* which can be commands.
-
- * examples/sys.clean-env.mk: add WITH[OUT]_ to
- MAKE_ENV_SAVE_PREFIX_LIST.
- Mention that HOME=/var/empty might be a good idea.
-
-2012-11-08 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * sys.dependfile.mk: if not depend file exists, $MACHINE
- specific ones are supported but not the default,

- compare ${.MAKE.DEPENDFILE:E} against ${MACHINE} is more reliable.
- * meta.stage.mk: examine .MAKE.DEPENDFILE_PREFERENCE for any
- entries ending in .${MACHINE} to decide if qualified _dirdep is
- needed.
- * gendirdeps.mk: only produce unqualified deps if no
- .MAKE.DEPENDFILE_PREFERENCE ends in .${MACHINE}
- * meta.subdir.mk: apply SUBDIREPS_FILTER
-
-2012-04-20 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * install-mk (MK_VERSION): bump version to 20120420
- * add sys.dependfile.mk so we can experiment with
- .MAKE.DEPENDFILE_PREFERENCE
- * meta.autodep.mk: _DEPENDFILE is precious!
-
-2012-03-15 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * install-mk (MK_VERSION): bump version to 20120315
- * install-new.mk: avoid being interrupted
-
-2012-02-26 Simon J. Gerraty <sjg at bad.crufty.net>

-
- * install-mk (MK_VERSION): bump version to 20111201

- dealing with an odd Makefile.depend, when normally using
- Makefile.depend.${MACHINE}
-
-2011-11-22 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * install-mk (MK_VERSION): bump version to 20111122
- * meta.autodep.mk: add some debug output, be more crisp about
- updating. Use ${.ALLTARGETS:M*.o} as a clue for .depend
-
-2011-11-13 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * install-mk (MK_VERSION): bump version to 20111111
- it's too cool to miss
- * import meta* updates from Juniper sjg@
- o dirdeps.mk set DEP_MACHINE for Makefile.depend (when we are
- normally using Makefile.depend.${MACHINE}), handy for
- read-only manually maintained dependencies.
- o meta2deps.py add a clear 'ERROR:' token if an exception is raised.
- o gendirdeps.mk if ERROR: from meta2deps.py do not update
- anything.
-
-2011-10-30 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * install-new.mk separate the cmp and copy logic to its own function.

- o add meta2deps.py from Juniper sjg@
- o tweak gendirdeps.mk to work with meta2deps.py when not
- cross-building

- AUTOCONF_INPUTS (configure).
-
-2011-08-24 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * meta.autodep.mk: if we do not have OBJS, .depend isn't a useful
- trigger for updating Makefile.depend*
-
-2011-08-08 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * install-mk (MK_VERSION): bump version to 20110808

-
-2011-06-28 Simon J. Gerraty <sjg at bad.crufty.net>

-
-2011-03-29 Simon J. Gerraty <sjg at bad.crufty.net>
-

- can be used to debug level 0 only and DEBUG_MAKE_FLAGS for the rest.
- * sys.mk: re-define M_whence in terms of M_type.
- M_type is useful for checking if something is a builtin.
-
-2011-03-16 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * meta.stage.mk: add stage_symlinks and leverage StageLinks for
- stage_libs
-
-2011-03-10 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * dirdeps.mk: correct value for _depdir_files depends on
- .MAKE.DEPENDFILE
- Add our copyright - just to make it clear we have frobbed this
- quite a bit.
- DEP_MACHINE needs to be set to MACHINE each time, if using only
- Makefile.depend (cf. Makefile.depend.${MACHINE})
-
- * meta.stage.mk: meta mode version of staging
-
- * init.mk, final.mk: include local.*.mk to simplify customization
-
-2011-03-03 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * auto.obj.mk: just because we are doing mk destroy, we should
- still set .OBJDIR correctly if it exists.
-
- * install-mk (mksrc): do not exclude meta.sys.mk
-
-2011-03-01 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * host-target.mk: set/export _HOST_ARCH etc separately,

- correctly.
-
-2011-02-18 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * meta.sys.mk: throw an error if /dev/filemon is missing and we

-
-2010-09-24 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * install-mk (MK_VERSION): bump version to 20100919
- include dirdeps.mk et al from Juniper Networks,
- for meta mode - requires filemon(9).
- * sys.mk, subdir.mk: Add hooks for meta mode.
- we do this as meta.sys.mk, meta.autodep.mk and meta.subdir.mk
- to make turning it on/off simple.
-

-
-2010-06-10 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * sys.mk: Add a means of selectively turning on debug flags.
- Eg. DEBUG_MAKE_FLAGS=-dv DEBUG_MAKE_DIRS="*lib/sjg"
- will act as if we did make -dv if .CURDIR ends in lib/sjg
- DEBUG_MAKE_SYS_DIRS does the same thing, but we set the flags at
- the start of sys.mk rather than the end.
- This only makes sense for leaf dirs, so we check that
- .MAKE.LEVEL > 0
-
-2010-06-09 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * install-mk (MK_VERSION): bump version to 20100608

- do not install examples/*
- * FILES: add examples/sys.clean-env.mk

- this requires bmake-20100606 or later to work.
-
-2010-05-13 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * sys.mk (M_tA): better simulate the result of :tA if not available.
-
-2010-05-04 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * sys.mk: canonicalize MAKE_VERSION

- whereas we only care about <src-date>
-
-2010-04-25 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * install-mk: just warn about FORCE_{BSD,SYS}_MK being ignored

- fix/simplify the tests for when to run mkdep.
- * auto.dep.mk: add some explanation of how/what we do.
- * autodep.mk: skip the .OPTIONAL frobbing of .depend
- bmake's FROM_DEPEND flag makes it redundant.
-
-2010-04-13 Simon J. Gerraty <sjg at bad.crufty.net>
-
- * install-mk (MK_VERSION): bump version to 20100404
- * subdir.mk: protect from multiple inclusion using _SUBDIRUSE.

+2015-09-02 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * rst2htm.mk: allow for per target flags etc.
+
+2015-09-01 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): 20150901
+
+ * doc.mk: create dir if needed use DOC_INSTALL_OWN
+
+2015-06-15 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): 20150615
+
+ * auto.obj.mk: allow use of MAKEOBJDIRPREFIX too.
+ Follow make's normal precedence rules.
+
+ * gendirdeps.mk: allow customization of the header.
+ eg. for FreeBSD:
+ GENDIRDEPS_HEADER= echo '\# ${FreeBSD:L:@v@$$$v$$ @:M*F*}';
+
+ * meta.autodep.mk: ignore dirdeps.cache*
+
+ * meta.stage.mk: when bootstrapping options it can be handy to
+ throw warnings rather than errors for staging conflicts.
+
+ * meta.sys.mk: include local.meta.sys.mk for customization
+
+2015-06-06 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): 20150606
+
+ * dirdeps.mk: don't rely on manually maintained Makefile.depend
+ to set DEP_RELDIR and reset DIRDEPS.
+ By setting DEP_RELDIR ourselves we can skip :tA
+
+ * gendirdeps.mk: skip setting DEP_RELDIR.
+
+2015-05-24 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * dirdeps.mk: avoid wildcards like make(bootstrap*)
+
+2015-05-20 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): 20150520
+
+ * dirdeps.mk: when we are building dirdeps cache file we *want*
+ meta_oodate to look at all the Makefile.depend files, so
+ set .MAKE.DEPENDFILE to something that won't match.
+
+ * meta.stage.mk: for STAGE_AS_* basename of file may not be unique
+ so first use absolute path as key.
+ Also skip staging at level 0.
+
+2015-04-30 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): 20150430
+
+ * dirdeps.mk: fix _count_dirdeps for non-cache case.

+2015-04-16 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): 20150411
+ bump version
+
+ * own.mk: put AUTO_OBJ in OPTIONS_DEFAULT_NO rather than YES.
+ it is here mainly for documentation purposes, since
+ if using auto.obj.mk it is better done via sys.mk
+
+2015-04-01 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): 20150401
+
+ * meta2deps.sh: support @list

+ o skip bogus input files.
+ o treat 'M' and 'L' as both an 'R' and a 'W'
+
+2015-03-03 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): 20150303
+
+ * dirdeps.mk: if MK_DIRDEPS_CACHE is yes, use dirdeps-cache
+ which is built via sub-make so we have a .meta file to tell if
+ it is out-of-date.
+ The dirdeps-cache contains the same dependency rules that we
+ normaly construct on the fly.
+ This adds a few seconds overhead when the cache is out of date,
+ but for a large target, the savings can be significant (10-20min).
+
+2014-11-18 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): 20141118

+ * auto.obj.mk: Allow MK_AUTO_OBJ to set MKOBJDIRS=auto
+
+2014-11-11 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): 20141111
+
+ * mkopt.sh: use consistent semantics for _mk_opt and _mk_opts
+
+2014-11-09 Simon J. Gerraty <sjg at bad.crufty.net>

+ scripts in a manner compatible with options.mk
+
+2014-10-12 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * meta.stage.mk: ensure only _STAGED_DIRS under objroot are used
+ for GENDIRDEPS_FILTER to avoid surprises.
+
+2014-10-10 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * dirdeps.mk (NSkipHostDir): this needs SRCTOP prepended since by
+ the time it is applied to __depdirs they have.
+
+ * dirdeps.mk fix filtering of _machines since M_dep_qual_fixes
+ expects patterns like *.${MACHINE}
+
+ * cython.mk (pyprefix?): use pyprefix to find python bits
+ since prefix might be something else (where we install our
+ stuff)
+
+2014-09-11 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): 20140911

+2014-08-02 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): 20140801
+
+ * dep.mk: use explicit MKDEP_MK rather than overload MKDEP to
+ identify the autodep.mk variant.
+
+ * sys.dependfile.mk: delete .MAKE.DEPENDFILE if its
+ initial value does not match .MAKE.DEPENDFILE_PREFIX
+
+ * meta.autodep.mk: if _bootstrap_dirdeps add RELDIR to DIRDEPS

+
+2014-05-02 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * dirdeps.mk: accept -DWITHOUT_DIRDEPS (same a as -DNO_DIRDEPS)

+
+ * Fix spelling errors - patch from Pedro Giffuni
+
+2014-03-14 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): 20140314
+
+ * dirdeps.mk (beforedirdeps): a handy hook
+
+ * dirdeps.mk (DIRDEP_MAKE): allow the actual command we run
+ to visit leaf dirs to be intercepted (eg. for distributed

+
+ * dirdeps.mk (__depdirs): ensure // don't sneak in

+
+2014-02-09 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * options.mk: cleanup and simplify semanitcs
+ NO_* dominates all, if both WITH_* and WITHOUT_*

+ Ie. WITHOUT_ normally wins.
+
+2013-12-12 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): bump version
+ * meta2deps.py: convert to print function for python3 compat.
+ we also need to open files with mode 'r' rather than 'rb'
+ otherwise we get bytes instead of strings.
+
+2013-10-10 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): bump version
+
+ * dirdeps.mk: when TARGET_SPEC_VARS is more than just MACHINE
+ apply the same filtering (M_dep_qual_fixes) when setting _machines
+ as _build_dirs.
+ Also fix the filtering of Makefile.depend files - for reporting
+ what we are looking for (M_dep_qual_fixes can get confused by
+ Makefile.depend)
+ Add some more debug info.
+
+2013-09-04 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * gendirdeps.mk (_objtops): fix typo also

+
+2013-04-18 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * meta.stage.mk: set INSTALL to STAGE_INSTALL when making 'all'

+ * gendirdeps.mk: better mimic meta2deps handling of .dirdep files.
+ * meta.stage.mk (LN_CP_SCRIPT): Add LnCp to do the ln||cp dance
+ consistently.
+ * dirdeps.mk: better describe the dance in sys.mk for TARGET_SPEC.
+
+2013-03-18 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * gendirdeps.mk: revert the dance around .MAKE.DEPENDFILE_DEFAULT
+ it is simpler to just not update when say building for "host"
+ (where we know we apply filters to DIRDEPS), and using a
+ non-machine qualified dependfile.
+
+2013-03-16 Simon J. Gerraty <sjg at bad.crufty.net>

+
+
+2013-03-11 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * gendirdeps.mk: if .MAKE.DEPENDFILE_DEFAULT is not machine

+ * sys.clean-env.mk: move it from examples, we and others use it
+ "as is".
+ * FILES: add srctop.mk and options.mk
+ * own.mk: convert to using options.mk
+ which is modeled after FreeBSD's handling of MK_*
+ but more flexible.
+ This allows MK_* for boolean knobs to not be confused
+ with MK* which can be commands.
+
+ * examples/sys.clean-env.mk: add WITH[OUT]_ to

+ Mention that HOME=/var/empty might be a good idea.

+ * sys.mk (_DEBUG_MAKE_FLAGS): use indirection so that DEBUG_MAKE_FLAGS0
+ can be used to debug level 0 only and DEBUG_MAKE_FLAGS for the rest.
+ * sys.mk: re-define M_whence in terms of M_type.
+ M_type is useful for checking if something is a builtin.
+
+2011-03-16 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * meta.stage.mk: add stage_symlinks and leverage StageLinks for
+ stage_libs
+
+2011-03-10 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * dirdeps.mk: correct value for _depdir_files depends on
+ .MAKE.DEPENDFILE
+ Add our copyright - just to make it clear we have frobbed this
+ quite a bit.
+ DEP_MACHINE needs to be set to MACHINE each time, if using only
+ Makefile.depend (cf. Makefile.depend.${MACHINE})
+
+ * meta.stage.mk: meta mode version of staging
+
+ * init.mk, final.mk: include local.*.mk to simplify customization
+
+2011-03-03 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * auto.obj.mk: just because we are doing mk destroy, we should
+ still set .OBJDIR correctly if it exists.
+
+ * install-mk (mksrc): do not exclude meta.sys.mk
+
+2011-03-01 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * host-target.mk: set/export _HOST_ARCH etc separately,
+ catch junk resulting from uname -p, so we can find sys/Linux.mk
+ correctly.
+
+2011-02-18 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * meta.sys.mk: throw an error if /dev/filemon is missing and we
+ expected to be updating Makefile.depend*
+
+2011-02-14 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): bump version to 20110214
+ * meta.subdir.mk: add support for -DBOOTSTRAP_DEPENDFILES
+
+2010-09-25 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * meta.sys.mk: not valid for older bmake
+
+2010-09-24 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): bump version to 20100919
+ include dirdeps.mk et al from Juniper Networks,
+ for meta mode - requires filemon(9).
+ * sys.mk, subdir.mk: Add hooks for meta mode.
+ we do this as meta.sys.mk, meta.autodep.mk and meta.subdir.mk
+ to make turning it on/off simple.
+
+2010-06-16 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): bump version to 20100616
+ * fix typo in sys.mk
+
+2010-06-12 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): bump version to 20100612
+ * lib.mk: remove duplicate addition to SOBJS
+
+2010-06-10 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * sys.mk: Add a means of selectively turning on debug flags.
+ Eg. DEBUG_MAKE_FLAGS=-dv DEBUG_MAKE_DIRS="*lib/sjg"
+ will act as if we did make -dv if .CURDIR ends in lib/sjg
+ DEBUG_MAKE_SYS_DIRS does the same thing, but we set the flags at
+ the start of sys.mk rather than the end.
+ This only makes sense for leaf dirs, so we check that
+ .MAKE.LEVEL > 0
+
+2010-06-09 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): bump version to 20100608
+ * sys.mk: include sys.env.mk later so it can use M_ListToSkip et al.
+ * examples/sys.clean-env.mk: require MAKE_VERIONS >= 20100606
+ also make it easier for folk to tweak
+
+2010-06-08 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): bump version to 20100606
+ do not install examples/*
+ * FILES: add examples/sys.clean-env.mk
+ * examples/sys.clean-env.mk: use .export-env to handle MAKEOBJDIR
+ this requires bmake-20100606 or later to work.
+
+2010-05-13 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * sys.mk (M_tA): better simulate the result of :tA if not available.
+
+2010-05-04 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * sys.mk: canonicalize MAKE_VERSION
+ old versions reported bmake-<src-date> build-<build-date>
+ whereas we only care about <src-date>
+
+2010-04-25 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk: just warn about FORCE_{BSD,SYS}_MK being ignored
+ * lib.mk: we only build the shared lib if SHLIB_FULLVERSION
+ is !empty
+
+2010-04-22 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * dpadd.mk: use LDADD_* if defined.
+
+2010-04-21 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): bump version to 20100420
+ * sys/NetBSD.mk: add MACHINE_CPU to keep netbsd makefiles happy
+ * autoconf.mk allow AUTO_AUTOCONF
+
+2010-04-19 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * obj.mk: add objwarn to keep freebsd makefiles happy
+ * auto.obj.mk: ensure Mkdirs is available.
+ * FILES: add auto.dep.mk - a simpler version of autodep.mk
+ * dep.mk: auto.dep.mk does not do 'make depend' so ignore it if
+ asked to do that.
+ fix/simplify the tests for when to run mkdep.
+ * auto.dep.mk: add some explanation of how/what we do.
+ * autodep.mk: skip the .OPTIONAL frobbing of .depend
+ bmake's FROM_DEPEND flag makes it redundant.
+
+2010-04-13 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * install-mk (MK_VERSION): bump version to 20100404
+ * subdir.mk: protect from multiple inclusion using _SUBDIRUSE.
+ * obj.mk: protect from multiple inclusion even as bsd.obj.mk
+ Also create a target _SUBDIRUSE so that we can be used without
+ subdir.mk
+
+2010-04-12 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * dep.mk: use <> when .including so can override.
+
+2010-01-11 Simon J. Gerraty <sjg at bad.crufty.net>
+
+ * lib.mk (SHLIB_LINKS): ensure a string comparison.
+
+2010-01-04 Simon J. Gerraty <sjg at bad.crufty.net>

+ * sys/SunOS.mk: we need to export PATH
+
+2009-12-23 Simon J. Gerraty <sjg at void.crufty.net>
+
+ * install-mk (MK_VERSION): bump version
+ include rst2htm.mk
+
+2009-12-17 Simon J. Gerraty <sjg at void.crufty.net>
+
+ * sys.mk,libnames.mk add .-include <local.*>

+ this, so provide it if using native make.
+
+2009-12-10 Simon J. Gerraty <sjg at void.crufty.net>
+
+ * FILES: move all the platform *.sys.mk files to sys/*.mk

+
+ * install-mk (MK_VERSION): bump version
+ * host-target.mk: only export the expensive stuff

+
+2009-11-07 Simon J. Gerraty <sjg at void.crufty.net>
+
+ * install-mk (MK_VERSION): bump version
+ * lib.mk: if sys.mk doesn't give us an lorder, don't use it.
+ based on patch from Greg Olszewski.

+

+
+ * install-mk (MK_VERSION): 20030928

+
+2003-07-31 Simon J. Gerraty <sjg at void.crufty.net>

+ * install-mk: add ability to use cp -f when updating
+ destination .mk files. Also now possible to play games with
+ FORCE_SYS_MK=ln etc on *BSD machines to link /usr/share/mk/sys.mk
+ into dest - not recommended unless you seriously want to.
+
+2003-07-28 Simon J. Gerraty <sjg at void.crufty.net>
+

-
-# Much of the complexity here is for supporting cross-building.
-# If a tree does not support that, simply using plain Makefile.depend
-# should provide sufficient clue.
-# Otherwise the recommendation is to use Makefile.depend.${MACHINE}
-# as expected below.
-
-# Note: this file gets multiply included.
-# This is what we do with DIRDEPS
-
-# DIRDEPS:
-# This is a list of directories - relative to SRCTOP, it is
-# normally only of interest to .MAKE.LEVEL 0.
-# In some cases the entry may be qualified with a .<machine>
-# or .<target_spec> suffix (see TARGET_SPEC_VARS below),
-# for example to force building something for the pseudo
-# machines "host" or "common" regardless of current ${MACHINE}.
-#
-# All unqualified entries end up being qualified with .${TARGET_SPEC}
-# and partially qualified (if TARGET_SPEC_VARS has multiple
-# entries) are also expanded to a full .<target_spec>.
-# The _DIRDEP_USE target uses the suffix to set TARGET_SPEC
-# correctly when visiting each entry.
-#
-# The fully qualified directory entries are used to construct a
-# dependency graph that will drive the build later.
-#
-# Also, for each fully qualified directory target, we will search
-# using ${.MAKE.DEPENDFILE_PREFERENCE} to find additional
-# dependencies. We use Makefile.depend (default value for
-# .MAKE.DEPENDFILE_PREFIX) to refer to these makefiles to
-# distinguish them from others.
-#
-# Each Makefile.depend file sets DEP_RELDIR to be the
-# the RELDIR (path relative to SRCTOP) for its directory, and
-# since each Makefile.depend file includes dirdeps.mk, this
-# processing is recursive and results in .MAKE.LEVEL 0 learning the
-# dependencies of the tree wrt the initial directory (_DEP_RELDIR).
-#
-# BUILD_AT_LEVEL0
-# Indicates whether .MAKE.LEVEL 0 builds anything:
-# if "no" sub-makes are used to build everything,
-# if "yes" sub-makes are only used to build for other machines.
-# It is best to use "no", but this can require fixing some
-# makefiles to not do anything at .MAKE.LEVEL 0.
-#
-# TARGET_SPEC_VARS
-# The default value is just MACHINE, and for most environments
-# this is sufficient. The _DIRDEP_USE target actually sets
-# both MACHINE and TARGET_SPEC to the suffix of the current
-# target so that in the general case TARGET_SPEC can be ignored.
-#
-# If more than MACHINE is needed then sys.mk needs to decompose
-# TARGET_SPEC and set the relevant variables accordingly.
-# It is important that MACHINE be included in and actually be
-# the first member of TARGET_SPEC_VARS. This allows other
-# variables to be considered optional, and some of the treatment
-# below relies on MACHINE being the first entry.
-# Note: TARGET_SPEC cannot contain any '.'s so the target
-# triple used by compiler folk won't work (directly anyway).
-#
-# For example:
-#
-# # Always list MACHINE first,
-# # other variables might be optional.

-# _tspec := ${TARGET_SPEC:S/,/ /g}

+
+# Much of the complexity here is for supporting cross-building.
+# If a tree does not support that, simply using plain Makefile.depend
+# should provide sufficient clue.
+# Otherwise the recommendation is to use Makefile.depend.${MACHINE}
+# as expected below.
+
+# Note: this file gets multiply included.
+# This is what we do with DIRDEPS
+
+# DIRDEPS:
+# This is a list of directories - relative to SRCTOP, it is
+# normally only of interest to .MAKE.LEVEL 0.
+# In some cases the entry may be qualified with a .<machine>
+# or .<target_spec> suffix (see TARGET_SPEC_VARS below),
+# for example to force building something for the pseudo
+# machines "host" or "common" regardless of current ${MACHINE}.
+#
+# All unqualified entries end up being qualified with .${TARGET_SPEC}
+# and partially qualified (if TARGET_SPEC_VARS has multiple
+# entries) are also expanded to a full .<target_spec>.
+# The _DIRDEP_USE target uses the suffix to set TARGET_SPEC
+# correctly when visiting each entry.
+#
+# The fully qualified directory entries are used to construct a
+# dependency graph that will drive the build later.
+#
+# Also, for each fully qualified directory target, we will search
+# using ${.MAKE.DEPENDFILE_PREFERENCE} to find additional
+# dependencies. We use Makefile.depend (default value for
+# .MAKE.DEPENDFILE_PREFIX) to refer to these makefiles to
+# distinguish them from others.
+#
+# Before each Makefile.depend file is read, we set
+# DEP_RELDIR to be the RELDIR (path relative to SRCTOP) for
+# its directory, and DEP_MACHINE etc according to the .<target_spec>
+# represented by the suffix of the corresponding target.
+#
+# Since each Makefile.depend file includes dirdeps.mk, this
+# processing is recursive and results in .MAKE.LEVEL 0 learning the
+# dependencies of the tree wrt the initial directory (_DEP_RELDIR).
+#
+# BUILD_AT_LEVEL0
+# Indicates whether .MAKE.LEVEL 0 builds anything:
+# if "no" sub-makes are used to build everything,
+# if "yes" sub-makes are only used to build for other machines.
+# It is best to use "no", but this can require fixing some
+# makefiles to not do anything at .MAKE.LEVEL 0.
+#
+# TARGET_SPEC_VARS
+# The default value is just MACHINE, and for most environments
+# this is sufficient. The _DIRDEP_USE target actually sets
+# both MACHINE and TARGET_SPEC to the suffix of the current
+# target so that in the general case TARGET_SPEC can be ignored.
+#
+# If more than MACHINE is needed then sys.mk needs to decompose
+# TARGET_SPEC and set the relevant variables accordingly.
+# It is important that MACHINE be included in and actually be
+# the first member of TARGET_SPEC_VARS. This allows other
+# variables to be considered optional, and some of the treatment
+# below relies on MACHINE being the first entry.
+# Note: TARGET_SPEC cannot contain any '.'s so the target
+# triple used by compiler folk won't work (directly anyway).
+#
+# For example:
+#
+# # Always list MACHINE first,
+# # other variables might be optional.

-# NAME:
-# install-mk - install mk files
-#
-# SYNOPSIS:
-# install-mk [options] [var=val] [dest]
-#
-# DESCRIPTION:
-# This tool installs mk files in a semi-intelligent manner into
-# "dest".
-#
-# Options:
-#
-# -n just say what we want to do, but don't touch anything.
-#
-# -f use -f when copying sys,mk.
-#
-# -v be verbose
-#
-# -q be quiet
-#
-# -m "mode"
-# Use "mode" for installed files (444).
-#
-# -o "owner"
-# Use "owner" for installed files.
-#
-# -g "group"
-# Use "group" for installed files.
-#
-# var=val
-# Set "var" to "val". See below.
-#
-# All our *.mk files are copied to "dest" with appropriate
-# ownership and permissions.
-#
-# By default if a sys.mk can be found in a standard location
-# (that bmake will find) then no sys.mk will be put in "dest".
-#
-# SKIP_SYS_MK:
-# If set, we will avoid installing our 'sys.mk'
-# This is probably a bad idea.
-#
-# SKIP_BSD_MK:
-# If set, we will skip making bsd.*.mk links to *.mk
-#
-# sys.mk:
-#
-# By default (and provided we are not installing to the system
-# mk dir - '/usr/share/mk') we install our own 'sys.mk' which
-# includes a sys specific file, or a generic one.

+# NAME:
+# install-mk - install mk files
+#
+# SYNOPSIS:
+# install-mk [options] [var=val] [dest]
+#
+# DESCRIPTION:
+# This tool installs mk files in a semi-intelligent manner into
+# "dest".
+#
+# Options:
+#
+# -n just say what we want to do, but don't touch anything.
+#
+# -f use -f when copying sys,mk.
+#
+# -v be verbose
+#
+# -q be quiet
+#
+# -m "mode"
+# Use "mode" for installed files (444).
+#
+# -o "owner"
+# Use "owner" for installed files.
+#
+# -g "group"
+# Use "group" for installed files.
+#
+# var=val
+# Set "var" to "val". See below.
+#
+# All our *.mk files are copied to "dest" with appropriate
+# ownership and permissions.
+#
+# By default if a sys.mk can be found in a standard location
+# (that bmake will find) then no sys.mk will be put in "dest".
+#
+# SKIP_SYS_MK:
+# If set, we will avoid installing our 'sys.mk'
+# This is probably a bad idea.
+#
+# SKIP_BSD_MK:
+# If set, we will skip making bsd.*.mk links to *.mk
+#
+# sys.mk:
+#
+# By default (and provided we are not installing to the system
+# mk dir - '/usr/share/mk') we install our own 'sys.mk' which
+# includes a sys specific file, or a generic one.

-This script parses each "meta" file and extracts the
-information needed to deduce build and src dependencies.
-
-It works much the same as the original shell script, but is
-*much* more efficient.
-
-The parsing work is handled by the class MetaFile.
-We only pay attention to a subset of the information in the
-"meta" files. Specifically:
-
-'CWD' to initialize our notion.
-
-'C' to track chdir(2) on a per process basis
-
-'R' files read are what we really care about.
- directories read, provide a clue to resolving
- subsequent relative paths. That is if we cannot find
- them relative to 'cwd', we check relative to the last
- dir read.
-
-'W' files opened for write or read-write,
- for filemon V3 and earlier.
-
-'E' files executed.
-
-'L' files linked
-
-'V' the filemon version, this record is used as a clue
- that we have reached the interesting bit.

+"""
+This script parses each "meta" file and extracts the
+information needed to deduce build and src dependencies.
+
+It works much the same as the original shell script, but is
+*much* more efficient.
+
+The parsing work is handled by the class MetaFile.
+We only pay attention to a subset of the information in the
+"meta" files. Specifically:
+
+'CWD' to initialize our notion.
+
+'C' to track chdir(2) on a per process basis
+
+'R' files read are what we really care about.
+ directories read, provide a clue to resolving
+ subsequent relative paths. That is if we cannot find
+ them relative to 'cwd', we check relative to the last
+ dir read.
+
+'W' files opened for write or read-write,
+ for filemon V3 and earlier.
+
+'E' files executed.
+
+'L' files linked
+
+'V' the filemon version, this record is used as a clue
+ that we have reached the interesting bit.

-# NAME:
-# meta2deps.sh - extract useful info from .meta files
-#
-# SYNOPSIS:
-# meta2deps.sh SB="SB" "meta" ...
-#
-# DESCRIPTION:
-# This script looks each "meta" file and extracts the
-# information needed to deduce build and src dependencies.
-#
-# To do this, we extract the 'CWD' record as well as all the
-# syscall traces which describe 'R'ead, 'C'hdir and 'E'xec
-# syscalls.
-#
-# The typical meta file looks like::
-#.nf
-#
-# # Meta data file "path"
-# CMD "command-line"
-# CWD "cwd"
-# TARGET "target"
-# -- command output --
-# -- filemon acquired metadata --
-# # buildmon version 2
-# V 2
-# E "pid" "path"
-# R "pid" "path"
-# C "pid" "cwd"
-# R "pid" "path"
-# X "pid" "status"
-#.fi
-#
-# The fact that all the syscall entry lines start with a single
-# character make these files quite easy to process using sed(1).
-#
-# To simplify the logic the 'CWD' line is made to look like a
-# normal 'C'hdir entry, and "cwd" is remembered so that it can
-# be prefixed to any "path" which is not absolute.
-#
-# If the "path" being read ends in '.srcrel' it is the content
-# of (actually the first line of) that file that we are
-# interested in.
-#
-# Any "path" which lies outside of the sandbox "SB" is generally
-# not of interest and is ignored.
-#
-# The output, is a set of absolute paths with "SB" like:
-#.nf
-#
-# $SB/obj-i386/bsd/gnu/lib/csu
-# $SB/obj-i386/bsd/gnu/lib/libgcc
-# $SB/obj-i386/bsd/include
-# $SB/obj-i386/bsd/lib/csu/i386-elf
-# $SB/obj-i386/bsd/lib/libc
-# $SB/src/bsd/include
-# $SB/src/bsd/sys/i386/include
-# $SB/src/bsd/sys/sys
-# $SB/src/pan-release/rtsock
-# $SB/src/pfe-shared/include/jnx
-#.fi
-#
-# Which can then be further processed by 'gendirdeps.mk'
-#
-# If we are passed 'DPDEPS='"dpdeps", then for each src file
-# outside of "CURDIR" we read, we output a line like:
-#.nf
-#
-# DPDEPS_$path += $RELDIR
-#.fi
-#
-# with "$path" geting turned into reldir's, so that we can end
-# up with a list of all the directories which depend on each src
-# file in another directory. This can allow for efficient yet
-# complete testing of changes.

-mk-files
-********
-
-The term ``mk-files`` refers to a collection of ``*.mk`` files.
-
-You need bmake_ or a *recent* NetBSD_ make.
-If in doubt use bmake_.
-
-Introduction
-============
-
-Many years ago, when building large software projects, I used GNU make
-(or my own patched version of it), and had developed a set of macros
-to simplify developing complex build trees.
-
-Since the early 90's my main development machines, run BSD
-(NetBSD_ to be precise), and the BSD source tree is good example of a
-large software project. It quickly became clear that
-``/usr/share/mk/*.mk`` were a great model, but were quite tightly
-linked to building the BSD tree.
-
-Much as I liked using NetBSD, my customers were more likely to be
-using SunOS, HP-UX etc, so I started on bmake_ and a portable collection
-of mk-files (mk.tar.gz_). NetBSD provided much of the original structure.
-
-Since then I've added a lot of features to NetBSD's make and hence to
-bmake which is kept closely in sync. The mk-files however have
-diverged quite a bit, though ideas are still picked up from NetBSD.
-
-Basics
-------
-
-The BSD build model is very simple. A directory produces one
-component, which is generally either a library or a program.
-Library makefiles include ``lib.mk`` and programs include ``prog.mk``
-and they *do the right thing*.
-
-A simple library makefile might look like::
-
- LIB = sig
-
- SRCS = \
- sigaction.c \
- sigcompat.c \
- sighdl.c
-
- .include <lib.mk>
-
-a simple program makefile::
-
- PROG = cat
-
- SRCS = cat.c
-
- .include <prog.mk>
-
-in such cases even the ``SRCS`` line is unnecessary as ``prog.mk``
-will default it to ``${PROG}.c``.
-
-It is the sensible use of defaults and the plethora of macro modifiers
-provided by bmake_ that allow simple makefiles such as the above
-*just work* on many different systems.
-
-
-mk-files
-========
-
-This section provides a brief description of some of the ``*.mk``
-files.
-
-sys.mk
-------
-
-When bmake starts, it looks for ``sys.mk`` and reads it before doing
-anything else. Thus, this is the place to setup the environment for
-everyone else.
-
-In this distribution, sys.mk avoids doing anything platform dependent.
-It is quite short, and includes a number of other files (which may or
-may not exists)
-
-sys.env.mk
- If it exists, is expected to do things like conditioning the
- environment. Since it will only be included by the initial
- instance of bmake, it should ``.export`` anything that
- sub-makes might need.
-
-examples/sys.clean-env.mk
- An example of how to clean the environment.
- See the file for all the details::
-
- .if ${MAKE_VERSION} >= 20100606 && ${.MAKE.LEVEL} == 0
- # we save any env var that starts with these
- MAKE_SAVE_ENV_PREFIX += SB MK MAKE MACHINE NEED_ CCACHE DISTCC USE_ SSH
- MAKE_SAVE_ENV_VARS += \
- PATH HOME USER LOGNAME \
- SRCTOP OBJTOP OBJROOT \
- ${_env_vars}
-
- _env_vars != env | egrep '^(${MAKE_SAVE_ENV_PREFIX:ts|})' | sed 's,=.*,,'; echo
- _export_list =
- .for v in ${MAKE_SAVE_ENV_VARS:O:u}
- .if !empty($v)
- _export_list += $v
- $v := ${$v}
- .endif
- .endfor
- # now clobber the environment
- .unexport-env
-
- # list of vars that we handle specially below
- _tricky_env_vars = MAKEOBJDIR
- # export our selection - sans tricky ones
- .export ${_export_list:${_tricky_env_vars:${M_ListToSkip}}}
-
- # this next bit may need tweaking
- .if defined(MAKEOBJDIR)
- srctop := ${SRCTOP:U${SB_SRC:U${SB}/src}}
- objroot := ${OBJROOT:U${SB_OBJROOT:U${SB}/${SB_OBJPREFIX}}}
- # we'll take care of MACHINE below
- objtop := ${OBJTOP:U${objroot}${MACHINE}}
- .if !empty(objtop)
- # we would normally want something like (/bin/sh):
- # MAKEOBJDIR="\${.CURDIR:S,${SRCTOP},${OBJROOT}\${MACHINE},}"
- # the $$ below is how we achieve the same result here.
- # since everything saved from the environment above
- # has run through := we need to compensate for ${MACHINE}
- MAKEOBJDIR = $${.CURDIR:S,${srctop},${objtop:S,${MACHINE},\${MACHINE},},}
-
- # export these as-is, and do not track...
- .export-env ${_tricky_env_vars}
- # now evaluate for ourselves
- .for v in ${_tricky_env_vars}
- $v := ${$v}
- .endfor
-
- .endif
- .endif
- .endif
-
-
-host-target.mk
- Is used to set macros like ``HOST_TARGET``, ``HOST_OS`` and
- ``host_os`` which are used to find the next step.
-
-sys/\*.mk
- Platform specific additions, such as ``Darwin.mk`` or ``SunOS.mk``
- set things like ``HOST_LIBEXT = .dylib`` for Darwin or
- ``SHLIB_FULLVERSION = ${SHLIB_MAJOR}`` for SunOS 5.
- If there is no OS specific file, ``sys/Generic.mk`` is used.
-
-local.sys.mk
- Any ``local.*.mk`` file is not part of the distribution.
- This provides a hook for sites to do extra setup without
- having to edit the distributed files.
-
-
-The above arrangement makes it easy for the mk files to be part of a
-src tree on an NFS volume and to allow building on multiple platforms.
-
-lib.mk
-------
-
-This file is used to build a number of different libraries from the
-same SRCS.
-
-lib${LIB}.a
- An archive lib of ``.o`` files, this is the default
-
-lib${LIB}_p.a
- A profiled lib of ``.po`` files.
- Still an archive lib, but all the objects are built with
- profiling in mind - hence the different extension.
- It is skipped if ``MKPROFILE`` is "no".
-
-lib${LIB}_pic.a
- An archive of ``.so`` objects compiled for relocation.
- On NetBSD this is the input to ``lib${LIB}.${LD_so}``, it is
- skipped if ``MKPICLIB`` is "no".
-
-lib${LIB}.${LD_so}
- A shared library. The value of ``LD_so`` is very platform
- specific. For example::
-
- # SunOS 5 and most other ELF systems
- libsslfd.so.1
-
- # Darwin
- libsslfd.1.dylib
-
- This library will only be built if ``SHLIB_MAJOR`` has
- a value, and ``MKPIC`` is not set to "no".
-
-There is a lot of platform specific tweaking in ``lib.mk``, largely the
-result of the original distributions trying to avoid interfering with
-the system's ``sys.mk``.
-
-libnames.mk
------------
-
-This is included by both ``prog.mk`` and ``lib.mk`` and tries to
-include ``*.libnames.mk`` of which:
-
-local.libnames.mk
- does not exist unless you create it. It is a handy way for you
- to customize without touching the distributed files.
- For example, on a test machine I needed to build openssl but
- not install it, so put the following in ``local.libnames.mk``::
-
- .if ${host_os} == "sunos"
- LIBCRYPTO = ${OBJTOP}/openssl/lib/crypto/libcrypto${DLIBEXT}
- LIBSSL = ${OBJTOP}/openssl/lib/ssl/libssl${DLIBEXT}
- INCLUDES_libcrypto = -I${OBJ_libcrypto}
- .endif
-
- The makefile created an openssl dir in ``${OBJ_libcrypto}`` to
- gather all the headers. dpadd.mk_ did the rest.
-
-sjg.libnames.mk
- not part of the mk-files distribution.
-
-host.libnames.mk
- contains logic to find any libs named in ``HOST_LIBS`` in
- ``HOST_LIBDIRS``.
-
-Each file above gets an opportunity to define things like::
-
- LIBSSLFD ?= ${OBJTOP}/ssl/lib/sslfd/libsslfd${DLIBEXT}
- INCLUDES_libsslfd = -I${SRC_libsslfd}/h -I${OBJ_libslfd}
-
-these are used by dpadd.mk_ and will be explained below.
-
-dpadd.mk
---------
-
-This file looks like line noise, and is best considered read-only.
-However it provides some very useful functionality, which simplifies the build.
-
-Makefiles can use the LIB* macros defined via libnames.mk_ or anywhere
-else in various ways::
-
- # indicate that we need to include headers from LIBCRYPTO
- # this would result in ${INCLUDES_libcrypto} being added to CFLAGS.
- SRC_LIBS += ${LIBCRYPTO}
-
- # indicate that libsslfd must be built already.
- # it also has the same effect as SRC_LIBS
- DPADD += ${LIBSSLFD}
-
- # indicate that not only must libsslfd be built,
- # but that we need to link with it.
- # this is almost exactly equivalent to
- # DPADD += ${LIBSSLFD}
- # LDADD += -L${LIBSSLFD:H} -lsslfd
- # and mostly serves to ensure that DPADD and LDADD are in sync.
- DPLIBS += ${LIBSSLFD}
-
-Any library (referenced by its full path) in any of the above, is
-added to ``DPMAGIC_LIBS`` with the following results, for each lib *foo*.
-
-SRC_libfoo
- Is set to indicate where the src for libfoo is.
- By default it is derived from ``LIBFOO`` by replacing
- ``${OBJTOP}`` with ``${SRCTOP}``.
-
-OBJ_libfoo
- Not very exciting, is just the dir where libfoo lives.
-
-INCLUDES_libfoo
- What to add to ``CFLAGS`` to find the public headers.
- The default varies. If ``${SRC_libfoo}/h`` exists, it is assumed
- to be the home of all public headers and thus the default is
- ``-I${SRC_libfoo}/h``
-
- Otherwise we make no assumptions and the default is
- ``-I${SRC_libfoo} -I${OBJ_libfoo}``
-
-LDADD_libfoo
- This only applies to libs reference via ``DPLIBS``.
- The default is ``-lfoo``, ``LDADD_*`` provides a hook to
- instantiate other linker flags at the appropriate point
- without losing the benfits of ``DPLIBS``.
-
-prog.mk
--------
-
-Compiles the specified SRCS and links them and the nominated libraries
-into a program. Prog makefiles usually need to list the libraries
-that need to be linked. We prefer use of ``DPLIBS`` but the more
-traditional ``DPADD`` and ``LDADD`` work just as well.
-That is::
-
- DPLIBS += ${LIBCRYPTO}
-
-is equivalent to::
-
- DPADD += ${LIBCRYPTO}
- LDADD += -lcrypto
-
-obj.mk
-------
-
-One of the cool aspects of BSD make, is its support for separating
-object files from the src tree. This is also the source of much
-confusion to some.
-
-Traditionally one had to do a separate ``make obj`` pass through the
-tree. If ``MKOBJDIRS`` is "auto", we include auto.obj.mk_.
-
-auto.obj.mk
------------
-
-This leverages the ``.OBJDIR`` target introduced some years ago to
-NetBSD make, to automatically create the desired object dir.
-
-subdir.mk
----------
-
-This is the traditional means of walking the tree. A makefile sets
-``SUBDIR`` to the list of sub-dirs to visit.
-
-If ``SUBDIR_MUST_EXIST`` is set, missing directories cause an error,
-otherwise a warning is issued. If you don't even want the warning,
-set ``MISSING_DIR=continue``.
-
-Traditionally, ``subdir.mk`` prints clue as it visits each subdir::
-
- ===> ssl
- ===> ssl/lib
- ===> ssl/lib/sslfd
-
-you can suppress that - or enhance it by setting ``ECHO_DIR``::
-
- # suppress subdir noise
- ECHO_DIR=:
- # print time stamps
- ECHO_DIR=echo @ `date "+%s [%Y-%m-%d %T] "`
-
-links.mk
---------
-
-Provides rules for processing lists of ``LINKS`` and ``SYMLINKS``.
-Each is expected to be a list of ``link`` and ``target`` pairs
-(``link`` -> ``target``).
-
-The logic is generally in a ``_*_SCRIPT`` which is referenced in a
-``_*_USE`` (``.USE``) target.
-
-The ``_BUILD_*`` forms are identical, but do not use ``${DESTDIR}``
-and so are useful for creating symlinks during the build phase.
-For example::
-
- SYMLINKS += ${.CURDIR}/${MACHINE_ARCH}/include machine
- header_links: _BUILD_SYMLINKS_USE
-
- md.o: header_links
-
-would create a symlink called ``machine`` in ``${.OBJDIR}`` pointing to
-``${.CURDIR}/${MACHINE_ARCH}/include`` before compiling ``md.o``
-
-
-autoconf.mk
------------
-
-Deals with running (or generating) GNU autoconf ``configure`` scripts.
-
-dep.mk
-------
-
-Deals with collecting dependencies. Another useful feature of BSD
-make is the separation of this sort of information into a ``.depend``
-file. ``MKDEP`` needs to point to a suitable tool (like mkdeps.sh_)
-
-If ``USE_AUTODEP_MK`` is "yes" includes autodep.mk_
-
-autodep.mk
-----------
-
-Leverages the ``-MD`` feature of recent GCC to collect dependency
-information as a side effect of compilation. With this GCC puts
-dependency info into a ``.d`` file.
-
-Unfortunately GCC bases the name of the ``.d`` file on the name of the
-input rather than the output file, which causes problems when the same
-source is compiled different ways. The latest GCC supports ``-MF`` to
-name the ``.d`` file and ``-MT`` to control the name to put as the
-dependent.
-
-Recent bmake allows dependencies for the ``.END`` target (run at the
-end if everything was successful), and ``autodep.mk`` uses this to
-post process the ``.d`` files into ``.depend``.
-
-auto.dep.mk
------------
-
-A much simpler implementation than autodep.mk_ it uses
-``-MF ${.TARGET:T}.d``
-to avoid possible conflicts during parallel builds.
-This precludes the use of suffix rules to drive ``make depend``, so
-dep.mk_ handles that if specifically requested.
-
-own.mk
-------
-
-Normally included by ``init.mk`` (included by ``lib.mk`` and
-``prog.mk`` etc), sets macros for default ownership etc.
-
-It includes ``${MAKECONF}`` if it is defined and exists.
-
-man.mk
-------
-
-Deals with man pages.
-
-warnings.mk
------------
-
-This provides a means of fine grained control over warnings on a per
-``${MACHINE}`` or even file basis.
-
-A makefile sets ``WARNINGS_SET`` to name a list of warnings
-and individual ``W_*`` macros can be used to tweak them.
-For example::
-
- WARNINGS_SET = HIGH
- W_unused_sparc = -Wno-unused
-
-would add all the warnings in ``${HIGH_WARNINGS}`` to CFLAGS, but
-on sparc, ``-Wno-unused`` would replace ``-Wunused``.
-
-You should never need to edit ``warnings.mk``, it will include
-``warnings-sets.mk`` if it exists and you use that to make any local
-customizations.
-
-Meta mode
-=========
-
-The 20110505 and later versions of ``mk-files`` include a number of
-makefile contributed by Juniper Networks, Inc.
-These allow the latest version of bmake_ to run in `meta mode`_.
-
-.. _`meta mode`: bmake-meta-mode.htm
-
-Install
-=======
-
-You can use the content of mk.tar.gz_ without installing at all.
-
-The script ``install-mk`` takes care of copying ``*.mk`` into a
-destination directory, and unless told not to, create ``bsd.*.mk`` links
-for ``lib.mk`` etc.
-
-If you just want to create the ``bsd.*.mk`` links in the directory
-where you unpacked the tar file, you can::
-
- ./mk/install-mk ./mk

+mk-files
+********
+
+The term ``mk-files`` refers to a collection of ``*.mk`` files.
+
+You need bmake_ or a *recent* NetBSD_ make.
+If in doubt use bmake_.
+
+Introduction
+============
+
+Many years ago, when building large software projects, I used GNU make
+(or my own patched version of it), and had developed a set of macros
+to simplify developing complex build trees.
+
+Since the early 90's my main development machines, run BSD
+(NetBSD_ to be precise), and the BSD source tree is good example of a
+large software project. It quickly became clear that
+``/usr/share/mk/*.mk`` were a great model, but were quite tightly
+linked to building the BSD tree.
+
+Much as I liked using NetBSD, my customers were more likely to be
+using SunOS, HP-UX etc, so I started on bmake_ and a portable collection
+of mk-files (mk.tar.gz_). NetBSD provided much of the original structure.
+
+Since then I've added a lot of features to NetBSD's make and hence to
+bmake which is kept closely in sync. The mk-files however have
+diverged quite a bit, though ideas are still picked up from NetBSD.
+
+Basics
+------
+
+The BSD build model is very simple. A directory produces one
+component, which is generally either a library or a program.
+Library makefiles include ``lib.mk`` and programs include ``prog.mk``
+and they *do the right thing*.
+
+A simple library makefile might look like::
+
+ LIB = sig
+
+ SRCS = \
+ sigaction.c \
+ sigcompat.c \
+ sighdl.c
+
+ .include <lib.mk>
+
+a simple program makefile::
+
+ PROG = cat
+
+ SRCS = cat.c
+
+ .include <prog.mk>
+
+in such cases even the ``SRCS`` line is unnecessary as ``prog.mk``
+will default it to ``${PROG}.c``.
+
+It is the sensible use of defaults and the plethora of macro modifiers
+provided by bmake_ that allow simple makefiles such as the above
+*just work* on many different systems.
+
+
+mk-files
+========
+
+This section provides a brief description of some of the ``*.mk``
+files.
+
+sys.mk
+------
+
+When bmake starts, it looks for ``sys.mk`` and reads it before doing
+anything else. Thus, this is the place to setup the environment for
+everyone else.
+
+In this distribution, sys.mk avoids doing anything platform dependent.
+It is quite short, and includes a number of other files (which may or
+may not exists)
+
+sys.env.mk
+ If it exists, is expected to do things like conditioning the
+ environment. Since it will only be included by the initial
+ instance of bmake, it should ``.export`` anything that
+ sub-makes might need.
+
+examples/sys.clean-env.mk
+ An example of how to clean the environment.
+ See the file for all the details::
+
+ .if ${MAKE_VERSION} >= 20100606 && ${.MAKE.LEVEL} == 0
+ # we save any env var that starts with these
+ MAKE_SAVE_ENV_PREFIX += SB MK MAKE MACHINE NEED_ CCACHE DISTCC USE_ SSH
+ MAKE_SAVE_ENV_VARS += \
+ PATH HOME USER LOGNAME \
+ SRCTOP OBJTOP OBJROOT \
+ ${_env_vars}
+
+ _env_vars != env | egrep '^(${MAKE_SAVE_ENV_PREFIX:ts|})' | sed 's,=.*,,'; echo
+ _export_list =
+ .for v in ${MAKE_SAVE_ENV_VARS:O:u}
+ .if !empty($v)
+ _export_list += $v
+ $v := ${$v}
+ .endif
+ .endfor
+ # now clobber the environment
+ .unexport-env
+
+ # list of vars that we handle specially below
+ _tricky_env_vars = MAKEOBJDIR
+ # export our selection - sans tricky ones
+ .export ${_export_list:${_tricky_env_vars:${M_ListToSkip}}}
+
+ # this next bit may need tweaking
+ .if defined(MAKEOBJDIR)
+ srctop := ${SRCTOP:U${SB_SRC:U${SB}/src}}
+ objroot := ${OBJROOT:U${SB_OBJROOT:U${SB}/${SB_OBJPREFIX}}}
+ # we'll take care of MACHINE below
+ objtop := ${OBJTOP:U${objroot}${MACHINE}}
+ .if !empty(objtop)
+ # we would normally want something like (/bin/sh):
+ # MAKEOBJDIR="\${.CURDIR:S,${SRCTOP},${OBJROOT}\${MACHINE},}"
+ # the $$ below is how we achieve the same result here.
+ # since everything saved from the environment above
+ # has run through := we need to compensate for ${MACHINE}
+ MAKEOBJDIR = $${.CURDIR:S,${srctop},${objtop:S,${MACHINE},\${MACHINE},},}
+
+ # export these as-is, and do not track...
+ .export-env ${_tricky_env_vars}
+ # now evaluate for ourselves
+ .for v in ${_tricky_env_vars}
+ $v := ${$v}
+ .endfor
+
+ .endif
+ .endif
+ .endif
+
+
+host-target.mk
+ Is used to set macros like ``HOST_TARGET``, ``HOST_OS`` and
+ ``host_os`` which are used to find the next step.
+
+sys/\*.mk
+ Platform specific additions, such as ``Darwin.mk`` or ``SunOS.mk``
+ set things like ``HOST_LIBEXT = .dylib`` for Darwin or
+ ``SHLIB_FULLVERSION = ${SHLIB_MAJOR}`` for SunOS 5.
+ If there is no OS specific file, ``sys/Generic.mk`` is used.
+
+local.sys.mk
+ Any ``local.*.mk`` file is not part of the distribution.
+ This provides a hook for sites to do extra setup without
+ having to edit the distributed files.
+
+
+The above arrangement makes it easy for the mk files to be part of a
+src tree on an NFS volume and to allow building on multiple platforms.
+
+lib.mk
+------
+
+This file is used to build a number of different libraries from the
+same SRCS.
+
+lib${LIB}.a
+ An archive lib of ``.o`` files, this is the default
+
+lib${LIB}_p.a
+ A profiled lib of ``.po`` files.
+ Still an archive lib, but all the objects are built with
+ profiling in mind - hence the different extension.
+ It is skipped if ``MKPROFILE`` is "no".
+
+lib${LIB}_pic.a
+ An archive of ``.so`` objects compiled for relocation.
+ On NetBSD this is the input to ``lib${LIB}.${LD_so}``, it is
+ skipped if ``MKPICLIB`` is "no".
+
+lib${LIB}.${LD_so}
+ A shared library. The value of ``LD_so`` is very platform
+ specific. For example::
+
+ # SunOS 5 and most other ELF systems
+ libsslfd.so.1
+
+ # Darwin
+ libsslfd.1.dylib
+
+ This library will only be built if ``SHLIB_MAJOR`` has
+ a value, and ``MKPIC`` is not set to "no".
+
+There is a lot of platform specific tweaking in ``lib.mk``, largely the
+result of the original distributions trying to avoid interfering with
+the system's ``sys.mk``.
+
+libnames.mk
+-----------
+
+This is included by both ``prog.mk`` and ``lib.mk`` and tries to
+include ``*.libnames.mk`` of which:
+
+local.libnames.mk
+ does not exist unless you create it. It is a handy way for you
+ to customize without touching the distributed files.
+ For example, on a test machine I needed to build openssl but
+ not install it, so put the following in ``local.libnames.mk``::
+
+ .if ${host_os} == "sunos"
+ LIBCRYPTO = ${OBJTOP}/openssl/lib/crypto/libcrypto${DLIBEXT}
+ LIBSSL = ${OBJTOP}/openssl/lib/ssl/libssl${DLIBEXT}
+ INCLUDES_libcrypto = -I${OBJ_libcrypto}
+ .endif
+
+ The makefile created an openssl dir in ``${OBJ_libcrypto}`` to
+ gather all the headers. dpadd.mk_ did the rest.
+
+sjg.libnames.mk
+ not part of the mk-files distribution.
+
+host.libnames.mk
+ contains logic to find any libs named in ``HOST_LIBS`` in
+ ``HOST_LIBDIRS``.
+
+Each file above gets an opportunity to define things like::
+
+ LIBSSLFD ?= ${OBJTOP}/ssl/lib/sslfd/libsslfd${DLIBEXT}
+ INCLUDES_libsslfd = -I${SRC_libsslfd}/h -I${OBJ_libslfd}
+
+these are used by dpadd.mk_ and will be explained below.
+
+dpadd.mk
+--------
+
+This file looks like line noise, and is best considered read-only.
+However it provides some very useful functionality, which simplifies the build.
+
+Makefiles can use the LIB* macros defined via libnames.mk_ or anywhere
+else in various ways::
+
+ # indicate that we need to include headers from LIBCRYPTO
+ # this would result in ${INCLUDES_libcrypto} being added to CFLAGS.
+ SRC_LIBS += ${LIBCRYPTO}
+
+ # indicate that libsslfd must be built already.
+ # it also has the same effect as SRC_LIBS
+ DPADD += ${LIBSSLFD}
+
+ # indicate that not only must libsslfd be built,
+ # but that we need to link with it.
+ # this is almost exactly equivalent to
+ # DPADD += ${LIBSSLFD}
+ # LDADD += -L${LIBSSLFD:H} -lsslfd
+ # and mostly serves to ensure that DPADD and LDADD are in sync.
+ DPLIBS += ${LIBSSLFD}
+
+Any library (referenced by its full path) in any of the above, is
+added to ``DPMAGIC_LIBS`` with the following results, for each lib *foo*.
+
+SRC_libfoo
+ Is set to indicate where the src for libfoo is.
+ By default it is derived from ``LIBFOO`` by replacing
+ ``${OBJTOP}`` with ``${SRCTOP}``.
+
+OBJ_libfoo
+ Not very exciting, is just the dir where libfoo lives.
+
+INCLUDES_libfoo
+ What to add to ``CFLAGS`` to find the public headers.
+ The default varies. If ``${SRC_libfoo}/h`` exists, it is assumed
+ to be the home of all public headers and thus the default is
+ ``-I${SRC_libfoo}/h``
+
+ Otherwise we make no assumptions and the default is
+ ``-I${SRC_libfoo} -I${OBJ_libfoo}``
+
+LDADD_libfoo
+ This only applies to libs reference via ``DPLIBS``.
+ The default is ``-lfoo``, ``LDADD_*`` provides a hook to
+ instantiate other linker flags at the appropriate point
+ without losing the benfits of ``DPLIBS``.
+
+prog.mk
+-------
+
+Compiles the specified SRCS and links them and the nominated libraries
+into a program. Prog makefiles usually need to list the libraries
+that need to be linked. We prefer use of ``DPLIBS`` but the more
+traditional ``DPADD`` and ``LDADD`` work just as well.
+That is::
+
+ DPLIBS += ${LIBCRYPTO}
+
+is equivalent to::
+
+ DPADD += ${LIBCRYPTO}
+ LDADD += -lcrypto
+
+obj.mk
+------
+
+One of the cool aspects of BSD make, is its support for separating
+object files from the src tree. This is also the source of much
+confusion to some.
+
+Traditionally one had to do a separate ``make obj`` pass through the
+tree. If ``MKOBJDIRS`` is "auto", we include auto.obj.mk_.
+
+auto.obj.mk
+-----------
+
+This leverages the ``.OBJDIR`` target introduced some years ago to
+NetBSD make, to automatically create the desired object dir.
+
+subdir.mk
+---------
+
+This is the traditional means of walking the tree. A makefile sets
+``SUBDIR`` to the list of sub-dirs to visit.
+
+If ``SUBDIR_MUST_EXIST`` is set, missing directories cause an error,
+otherwise a warning is issued. If you don't even want the warning,
+set ``MISSING_DIR=continue``.
+
+Traditionally, ``subdir.mk`` prints clue as it visits each subdir::
+
+ ===> ssl
+ ===> ssl/lib
+ ===> ssl/lib/sslfd
+
+you can suppress that - or enhance it by setting ``ECHO_DIR``::
+
+ # suppress subdir noise
+ ECHO_DIR=:
+ # print time stamps
+ ECHO_DIR=echo @ `date "+%s [%Y-%m-%d %T] "`
+
+links.mk
+--------
+
+Provides rules for processing lists of ``LINKS`` and ``SYMLINKS``.
+Each is expected to be a list of ``link`` and ``target`` pairs
+(``link`` -> ``target``).
+
+The logic is generally in a ``_*_SCRIPT`` which is referenced in a
+``_*_USE`` (``.USE``) target.
+
+The ``_BUILD_*`` forms are identical, but do not use ``${DESTDIR}``
+and so are useful for creating symlinks during the build phase.
+For example::
+
+ SYMLINKS += ${.CURDIR}/${MACHINE_ARCH}/include machine
+ header_links: _BUILD_SYMLINKS_USE
+
+ md.o: header_links
+
+would create a symlink called ``machine`` in ``${.OBJDIR}`` pointing to
+``${.CURDIR}/${MACHINE_ARCH}/include`` before compiling ``md.o``
+
+
+autoconf.mk
+-----------
+
+Deals with running (or generating) GNU autoconf ``configure`` scripts.
+
+dep.mk
+------
+
+Deals with collecting dependencies. Another useful feature of BSD
+make is the separation of this sort of information into a ``.depend``
+file. ``MKDEP`` needs to point to a suitable tool (like mkdeps.sh_)
+
+If ``USE_AUTODEP_MK`` is "yes" includes autodep.mk_
+
+autodep.mk
+----------
+
+Leverages the ``-MD`` feature of recent GCC to collect dependency
+information as a side effect of compilation. With this GCC puts
+dependency info into a ``.d`` file.
+
+Unfortunately GCC bases the name of the ``.d`` file on the name of the
+input rather than the output file, which causes problems when the same
+source is compiled different ways. The latest GCC supports ``-MF`` to
+name the ``.d`` file and ``-MT`` to control the name to put as the
+dependent.
+
+Recent bmake allows dependencies for the ``.END`` target (run at the
+end if everything was successful), and ``autodep.mk`` uses this to
+post process the ``.d`` files into ``.depend``.
+
+auto.dep.mk
+-----------
+
+A much simpler implementation than autodep.mk_ it uses
+``-MF ${.TARGET:T}.d``
+to avoid possible conflicts during parallel builds.
+This precludes the use of suffix rules to drive ``make depend``, so
+dep.mk_ handles that if specifically requested.
+
+own.mk
+------
+
+Normally included by ``init.mk`` (included by ``lib.mk`` and
+``prog.mk`` etc), sets macros for default ownership etc.
+
+It includes ``${MAKECONF}`` if it is defined and exists.
+
+man.mk
+------
+
+Deals with man pages.
+
+warnings.mk
+-----------
+
+This provides a means of fine grained control over warnings on a per
+``${MACHINE}`` or even file basis.
+
+A makefile sets ``WARNINGS_SET`` to name a list of warnings
+and individual ``W_*`` macros can be used to tweak them.
+For example::
+
+ WARNINGS_SET = HIGH
+ W_unused_sparc = -Wno-unused
+
+would add all the warnings in ``${HIGH_WARNINGS}`` to CFLAGS, but
+on sparc, ``-Wno-unused`` would replace ``-Wunused``.
+
+You should never need to edit ``warnings.mk``, it will include
+``warnings-sets.mk`` if it exists and you use that to make any local
+customizations.
+
+rst2htm.mk
+----------
+
+Logic to simplify generating HTML (and PDF) documents from ReStructuredText.
+
+cython.mk
+---------
+
+Logic to build Python C interface modules using Cython_
+
+.. _Cython: http://www.cython.org/
+
+Meta mode
+=========
+
+The 20110505 and later versions of ``mk-files`` include a number of
+makefiles contributed by Juniper Networks, Inc.
+These allow the latest version of bmake_ to run in `meta mode`_
+see `dirdeps.mk`_
+
+.. _`dirdeps.mk`: /help/sjg/dirdeps.htm
+.. _`meta mode`: bmake-meta-mode.htm
+
+Install
+=======
+
+You can use the content of mk.tar.gz_ without installing at all.
+
+The script ``install-mk`` takes care of copying ``*.mk`` into a
+destination directory, and unless told not to, create ``bsd.*.mk`` links
+for ``lib.mk`` etc.
+
+If you just want to create the ``bsd.*.mk`` links in the directory
+where you unpacked the tar file, you can::
+
+ ./mk/install-mk ./mk

- * Functions to parse a makefile.
- *
- * One function, Parse_Init, must be called before any functions
- * in this module are used. After that, the function Parse_File is the
- * main entry point and controls most of the other functions in this
- * module.
- *
- * Most important structures are kept in Lsts. Directories for
- * the .include "..." function are kept in the 'parseIncPath' Lst, while
- * those for the .include <...> are kept in the 'sysIncPath' Lst. The
- * targets currently being defined are kept in the 'targets' Lst.
- *
- * The variables 'fname' and 'lineno' are used to track the name
- * of the current file and the line number in that file so that error
- * messages can be more meaningful.
- *
- * Interface:
- * Parse_Init Initialization function which must be
- * called before anything else in this module
- * is used.
- *
- * Parse_End Cleanup the module
- *
- * Parse_File Function used to parse a makefile. It must
- * be given the name of the file, which should
- * already have been opened, and a function
- * to call to read a character from the file.
- *
- * Parse_IsVar Returns TRUE if the given line is a
- * variable assignment. Used by MainParseArgs
- * to determine if an argument is a target
- * or a variable assignment. Used internally
- * for pretty much the same thing...
- *
- * Parse_Error Function called when an error occurs in
- * parsing. Used by the variable and
- * conditional modules.
- * Parse_MainName Returns a Lst of the main target to create.

+ * module.
+ *
+ * Most important structures are kept in Lsts. Directories for
+ * the .include "..." function are kept in the 'parseIncPath' Lst, while
+ * those for the .include <...> are kept in the 'sysIncPath' Lst. The
+ * targets currently being defined are kept in the 'targets' Lst.
+ *
+ * The variables 'fname' and 'lineno' are used to track the name
+ * of the current file and the line number in that file so that error
+ * messages can be more meaningful.
+ *
+ * Interface:
+ * Parse_Init Initialization function which must be
+ * called before anything else in this module
+ * is used.
+ *
+ * Parse_End Cleanup the module
+ *
+ * Parse_File Function used to parse a makefile. It must
+ * be given the name of the file, which should
+ * already have been opened, and a function
+ * to call to read a character from the file.
+ *
+ * Parse_IsVar Returns TRUE if the given line is a
+ * variable assignment. Used by MainParseArgs
+ * to determine if an argument is a target
+ * or a variable assignment. Used internally
+ * for pretty much the same thing...
+ *
+ * Parse_Error Function called when an error occurs in
+ * parsing. Used by the variable and
+ * conditional modules.
+ * Parse_MainName Returns a Lst of the main target to create.

- *
- * Suff_ClearSuffixes Clear out all the suffixes and defined
- * transformations.
- *
- * Suff_IsTransform Return TRUE if the passed string is the lhs
- * of a transformation rule.
- *
- * Suff_AddSuffix Add the passed string as another known suffix.
- *
- * Suff_GetPath Return the search path for the given suffix.

- * targ.c --
- * Functions for maintaining the Lst allTargets. Target nodes are
- * kept in two structures: a Lst, maintained by the list library, and a
- * hash table, maintained by the hash library.
- *
- * Interface:
- * Targ_Init Initialization procedure.
- *
- * Targ_End Cleanup the module
- *
- * Targ_List Return the list of all targets so far.
- *
- * Targ_NewGN Create a new GNode for the passed target
- * (string). The node is *not* placed in the
- * hash table, though all its fields are
- * initialized.
- *
- * Targ_FindNode Find the node for a given target, creating
- * and storing it if it doesn't exist and the
- * flags are right (TARG_CREATE)
- *
- * Targ_FindList Given a list of names, find nodes for all
- * of them. If a name doesn't exist and the
- * TARG_NOCREATE flag was given, an error message
- * is printed. Else, if a name doesn't exist,
- * its node is created.
- *
- * Targ_Ignore Return TRUE if errors should be ignored when
- * creating the given target.
- *
- * Targ_Silent Return TRUE if we should be silent when
- * creating the given target.
- *
- * Targ_Precious Return TRUE if the target is precious and
- * should not be removed if we are interrupted.
- *
- * Targ_Propagate Propagate information between related
- * nodes. Should be called after the
- * makefiles are parsed but before any
- * action is taken.
- *
- * Debugging:
- * Targ_PrintGraph Print out the entire graphm all variables
- * and statistics for the directory cache. Should
- * print something for suffixes, too, but...

+ * Interface:
+ * Targ_Init Initialization procedure.

+ * Targ_End Cleanup the module

+ * Targ_NewGN Create a new GNode for the passed target

+ *
+ * Targ_FindNode Find the node for a given target, creating
+ * and storing it if it doesn't exist and the
+ * flags are right (TARG_CREATE)
+ *
+ * Targ_FindList Given a list of names, find nodes for all
+ * of them. If a name doesn't exist and the

+ *
+ * Targ_Silent Return TRUE if we should be silent when

+ * Targ_Precious Return TRUE if the target is precious and

+# Test backslash escaping.
+
+# Extracts from the POSIX 2008 specification
+# <http://pubs.opengroup.org/onlinepubs/9699919799/utilities/make.html>:
+#
+# Comments start with a <number-sign> ( '#' ) and continue until an
+# unescaped <newline> is reached.
+#
+# When an escaped <newline> (one preceded by a <backslash>) is found
+# anywhere in the makefile except in a command line, an include
+# line, or a line immediately preceding an include line, it shall
+# be replaced, along with any leading white space on the following
+# line, with a single <space>.
+#
+# When an escaped <newline> is found in a command line in a
+# makefile, the command line shall contain the <backslash>, the
+# <newline>, and the next line, except that the first character of
+# the next line shall not be included if it is a <tab>.
+#
+# When an escaped <newline> is found in an include line or in a
+# line immediately preceding an include line, the behavior is
+# unspecified.
+#
+# Notice that the behaviour of <backslash><backslash> or
+# <backslash><anything other than newline> is not mentioned. I think
+# this implies that <backslash> should be taken literally everywhere
+# except before <newline>.
+#
+# Our practice, despite what POSIX might say, is that "\#"
+# in a variable assignment stores "#" as part of the value.
+# The "\" is not taken literally, and the "#" does not begin a comment.
+#
+# Also, our practice is that an even number of backslashes before a
+# newline in a variable assignment simply stores the backslashes as part
+# of the value, and treats the newline as though it was not escaped.
+# Similarly, ann even number of backslashes before a newline in a
+# command simply uses the backslashes as part of the command test, but
+# does not escape the newline. This is compatible with GNU make.

+# Issues from PR 49086
+
+# Issue 3: single suffix rules remain active after .SUFFIXES is cleared
+#
+# There's a rule for issue3.a, but .a is no longer a known suffix when
+# targets are being made, so issue3 should not get made.
+all: issue3
+
+# Issue 4: suffix rules do not become regular rules when .SUFFIXES is cleared
+#
+# When the rules were encountered, .a and .b were known suffices, but later
+# on they were forgotten. These should get created as regular targets.
+all: .a .a.b .b.a
+
+# Issue 5: adding more suffixes does not make existing rules into suffix rules
+#
+# When the targets .c.d, .d.c, .d, .d.e, and .e.d were encountered, only .a,
+# .b and .c were known suffixes, so all of them were regular rules. Later
+# rest of the suffixes were made known, so they should all be suffix
+# transformation rules.
+all: issue5a.d issue5b.c issue5c issue5d.e issue5e.d
+
+# Issue 6: transformation search can end up in an infinite loop
+#
+# There is no file or target from which issue6.f could be made from so
+# this should fail. The bug was that because rules .e.f, .d.e and .e.d
+# exist, make would try to make .f from .e and then infinitely try
+# to do .e from .d and vice versa.
+all: issue6.f
+
+# Issue 10: explicit dependencies affect transformation rule selection
+#
+# If issue10.e is wanted and both issue10.d and issue10.f are available,
+# make should choose the .d.e rule, because .d is before .f in .SUFFIXES.
+# The bug was that if issue10.d had an explicit dependency on issue10.f,
+# it would choose .f.e instead.
+all: issue10.e
+
+# Issue 11: sources from transformation rules are expanded incorrectly
+#
+# issue11.j should depend on issue11.i and issue11.second and issue11.i
+# should depend on issue11.h and issue11.first. The bug was that
+# the dynamic sources were expanded before ${.PREFIX} and ${.TARGET} were

- * Interface:
- * Var_Set Set the value of a variable in the given
- * context. The variable is created if it doesn't
- * yet exist. The value and variable name need not
- * be preserved.
- *
- * Var_Append Append more characters to an existing variable
- * in the given context. The variable needn't
- * exist already -- it will be created if it doesn't.
- * A space is placed between the old value and the
- * new one.
- *
- * Var_Exists See if a variable exists.
- *
- * Var_Value Return the value of a variable in a context or
- * NULL if the variable is undefined.
- *
- * Var_Subst Substitute named variable, or all variables if
- * NULL in a string using
- * the given context as the top-most one. If the
- * third argument is non-zero, Parse_Error is
- * called if any variables are undefined.
- *
- * Var_Parse Parse a variable expansion from a string and
- * return the result and the number of characters
- * consumed.
- *
- * Var_Delete Delete a variable in a context.
- *
- * Var_Init Initialize this module.
- *
- * Debugging:
- * Var_Dump Print out all variables defined in the given
- * context.

- * Substitute <pat2> for regex <pat1> in the value
- * :H Substitute the head of each word
- * :T Substitute the tail of each word
- * :E Substitute the extension (minus '.') of
- * each word
- * :R Substitute the root of each word
- * (pathname minus the suffix).
- * :O ("Order") Alphabeticaly sort words in variable.
- * :Ox ("intermiX") Randomize words in variable.
- * :u ("uniq") Remove adjacent duplicate words.
- * :tu Converts the variable contents to uppercase.
- * :tl Converts the variable contents to lowercase.
- * :ts[c] Sets varSpace - the char used to
- * separate words to 'c'. If 'c' is
- * omitted then no separation is used.
- * :tW Treat the variable contents as a single
- * word, even if it contains spaces.
- * (Mnemonic: one big 'W'ord.)
- * :tw Treat the variable contents as multiple
- * space-separated words.
- * (Mnemonic: many small 'w'ords.)
- * :[index] Select a single word from the value.
- * :[start..end] Select multiple words from the value.
- * :[*] or :[0] Select the entire value, as a single
- * word. Equivalent to :tW.
- * :[@] Select the entire value, as multiple
- * words. Undoes the effect of :[*].
- * Equivalent to :tw.
- * :[#] Returns the number of words in the value.
- *
- * :?<true-value>:<false-value>
- * If the variable evaluates to true, return
- * true value, else return the second value.
- * :lhs=rhs Like :S, but the rhs goes to the end of
- * the invocation.
- * :sh Treat the current value as a command
- * to be run, new value is its output.
- * The following added so we can handle ODE makefiles.
- * :@<tmpvar>@<newval>@
- * Assign a temporary local variable <tmpvar>
- * to the current value of each word in turn
- * and replace each word with the result of
- * evaluating <newval>
- * :D<newval> Use <newval> as value if variable defined
- * :U<newval> Use <newval> as value if variable undefined
- * :L Use the name of the variable as the value.
- * :P Use the path of the node that has the same
- * name as the variable as the value. This
- * basically includes an implied :L so that
- * the common method of refering to the path
- * of your dependent 'x' in a rule is to use
- * the form '${x:P}'.
- * :!<cmd>! Run cmd much the same as :sh run's the
- * current value of the variable.
- * The ::= modifiers, actually assign a value to the variable.
- * Their main purpose is in supporting modifiers of .for loop
- * iterators and other obscure uses. They always expand to
- * nothing. In a target rule that would otherwise expand to an
- * empty line they can be preceded with @: to keep make happy.
- * Eg.
- *
- * foo: .USE
- * .for i in ${.TARGET} ${.TARGET:R}.gz
- * @: ${t::=$i}
- * @echo blah ${t:T}
- * .endfor
- *
- * ::=<str> Assigns <str> as the new value of variable.
- * ::?=<str> Assigns <str> as value of variable if
- * it was not already set.
- * ::+=<str> Appends <str> to variable.
- * ::!=<cmd> Assigns output of <cmd> as the new value of
- * variable.

+ * Equivalent to :tw.
+ * :[#] Returns the number of words in the value.
+ *
+ * :?<true-value>:<false-value>
+ * If the variable evaluates to true, return
+ * true value, else return the second value.
+ * :lhs=rhs Like :S, but the rhs goes to the end of
+ * the invocation.
+ * :sh Treat the current value as a command
+ * to be run, new value is its output.
+ * The following added so we can handle ODE makefiles.
+ * :@<tmpvar>@<newval>@
+ * Assign a temporary local variable <tmpvar>
+ * to the current value of each word in turn
+ * and replace each word with the result of
+ * evaluating <newval>
+ * :D<newval> Use <newval> as value if variable defined
+ * :U<newval> Use <newval> as value if variable undefined
+ * :L Use the name of the variable as the value.
+ * :P Use the path of the node that has the same
+ * name as the variable as the value. This
+ * basically includes an implied :L so that
+ * the common method of refering to the path
+ * of your dependent 'x' in a rule is to use
+ * the form '${x:P}'.
+ * :!<cmd>! Run cmd much the same as :sh run's the
+ * current value of the variable.
+ * The ::= modifiers, actually assign a value to the variable.
+ * Their main purpose is in supporting modifiers of .for loop
+ * iterators and other obscure uses. They always expand to
+ * nothing. In a target rule that would otherwise expand to an
+ * empty line they can be preceded with @: to keep make happy.
+ * Eg.
+ *
+ * foo: .USE
+ * .for i in ${.TARGET} ${.TARGET:R}.gz
+ * @: ${t::=$i}
+ * @echo blah ${t:T}
+ * .endfor
+ *
+ * ::=<str> Assigns <str> as the new value of variable.
+ * ::?=<str> Assigns <str> as value of variable if
+ * it was not already set.
+ * ::+=<str> Appends <str> to variable.
+ * ::!=<cmd> Assigns output of <cmd> as the new value of
+ * variable.
