PLIST
generationPLIST_SRC
The PLIST
file contains a package's
“packing list”, i.e. a list of files that belong to
the package (relative to the ${PREFIX}
directory it's been installed in) plus some additional statements
- see the pkg_create(1) man page for a full list.
This chapter addresses some issues that need attention when
dealing with the PLIST
file (or files, see
below!).
Be sure to add a RCS ID line as the first thing in any
PLIST
file you write:
@comment $NetBSD $
An artificial space has been added between NetBSD and $, this is a workaround here to prevent CVS expanding to the filename of the guide. When adding the RCS ID the space should be omitted.
You can use the make print-PLIST command to output a PLIST that matches any new files since the package was extracted. See Section 13.17, “Other helpful targets” for more information on this target.
The PRINT_PLIST_AWK
variable takes a set
of AWK patterns and actions that are used to filter the output of
print-PLIST. You can append any chunk of AWK
scripting you like to it, but be careful with quoting.
For example, to get all files inside the
libdata/foo
directory removed from the
resulting PLIST:
PRINT_PLIST_AWK+= /^libdata\/foo/ { next; }
The PRINT_PLIST_AWK
transformations are
evaluated after the file list and directory list are sorted.
EARLY_PRINT_PLIST_AWK
is like
PRINT_PLIST_AWK
except it operates before the file
list and directory list are sorted.
A number of variables are substituted automatically in PLISTs when a package is installed on a system. This includes the following variables:
${MACHINE_ARCH}
, ${MACHINE_GNU_ARCH}
Some packages like emacs and perl embed information
about which architecture they were built on into the
pathnames where they install their files. To handle this
case, PLIST will be preprocessed before actually used, and
the symbol
“${MACHINE_ARCH}
” will be
replaced by what uname -p gives. The
same is done if the string
${MACHINE_GNU_ARCH}
is embedded in
PLIST somewhere - use this on packages that have GNU
autoconf-created configure scripts.
There used to be a symbol
“$ARCH
” that
was replaced by the output of uname
-m, but that's no longer supported and has
been removed.
${OPSYS}
, ${LOWER_OPSYS}
, ${OS_VERSION}
Some packages want to embed the OS name and version
into some paths. To do this, use these variables in the
PLIST
:
${OPSYS}
- output of “uname -s”
${LOWER_OPSYS}
- lowercase common name (eg. “solaris”)
${OS_VERSION}
- “uname -r”
For a list of values which are replaced by
default, the output of make help topic=PLIST_SUBST as
well as searching the pkgsrc/mk
directory with grep for
PLIST_SUBST
should help.
If you want to change other variables not listed above, you
can add variables and their expansions to this variable in the
following way, similar to MESSAGE_SUBST
(see Section 12.5, “Optional files”):
PLIST_SUBST+= SOMEVAR="somevalue"
This replaces all occurrences of “${SOMEVAR}”
in the PLIST
with
“somevalue”.
The PLIST_VARS
variable can be used to simplify
the common case of conditionally including some
PLIST
entries. It can be done by adding
and
setting the corresponding PLIST_VARS
+=fooPLIST.foo
variable
to yes
if the entry should be included.
This will substitute “${PLIST.foo}
”
in the PLIST
with either
“""
” or
“"@comment "
”.
For example, in Makefile
:
PLIST_VARS+= foo
.if condition
PLIST.foo= yes
.else
And then in PLIST
:
@comment $NetBSD $ bin/bar man/man1/bar.1 ${PLIST.foo}bin/foo ${PLIST.foo}man/man1/foo.1 ${PLIST.foo}share/bar/foo.data
An artificial space has been added between NetBSD and $, this is a workaround here to prevent CVS expanding to the filename of the guide. When adding the RCS ID the space should be omitted.
Man pages should be installed in compressed form if
MANZ
is set (in bsd.own.mk
),
and uncompressed otherwise. To handle this in the
PLIST
file, the suffix “.gz” is
appended/removed automatically for man pages according to
MANZ
and MANCOMPRESSED
being set
or not, see above for details. This modification of the
PLIST
file is done on a copy of it, not
PLIST
itself.
To use one or more files as source for the PLIST
used
in generating the binary package, set the variable
PLIST_SRC
to the names of that file(s).
The files are later concatenated using cat(1), and the order of things is
important. The default for PLIST_SRC
is
${PKGDIR}/PLIST
.
Some packages decide to install a different set of files based on the operating system being used. These differences can be automatically handled by using the following files:
PLIST.common
PLIST.${OPSYS}
PLIST.${MACHINE_ARCH}
PLIST.${OPSYS}-${MACHINE_ARCH}
PLIST.common_end
Some packages decide to generate hard-to-guess file names during installation that are hard to wire down.
In such cases, you can set the
GENERATE_PLIST
variable to shell code
terminated (with a semicolon) that will output PLIST entries which
will be appended to the PLIST
You can find one example in editors/xemacs:
GENERATE_PLIST+= ${ECHO} bin/${DISTNAME}-`${WRKSRC}/src/xemacs -sd`.dmp ;
which will append something like
bin/xemacs-21.4.23-54e8ea71.dmp
to the
PLIST
.
A “shared directory” is a directory where multiple (and unrelated) packages install files. These directories were problematic because you had to add special tricks in the PLIST to conditionally remove them, or have some centralized package handle them.
In pkgsrc, it is now easy: Each package should create directories and install files as needed; pkg_delete will remove any directories left empty after uninstalling a package.
If a package needs an empty directory to work, create the directory during installation as usual, and also add an entry to the PLIST:
@pkgdir path/to/empty/directory
or take a look at MAKE_DIRS
and
OWN_DIRS
.
