.Nm pkg_create
.Op Fl s Ar signature-parameter
.Fl f Ar packinglist
.Sh DESCRIPTION
The
.Nm
command is normally used to create a binary package named
.Ar pkg-name ,
for subsequent use with
.Xr pkg_add 1 ,
.Xr pkg_delete 1
and
.Xr pkg_info 1 .
.Ar pkg-name
will traditionally have a
.Dq .tgz
extension, to denote the underlying binary format.
.Ar pkg-name
must follow
.Xr packages-specs 7 .
.Pp
Use of the
.Xr ports 7
infrastructure instead of manual
.Nm
invocation is strongly recommended.
.Pp
.Nm
can also be used to recreate a binary package from an existing installation.
.Pp
During package creation,
.Nm
replaces too long file names with smaller equivalents
.Po
see
.Xr package 5
.Pc ,
records extra information in the packing-list, such as the existence
of symlinks and hard links, computes and stores file checksums, and
verifies that all special objects are properly annotated in the packing-list.
.Pp
It will also check all required shared libraries
for reachability, by looking into all installed dependencies.
It may also ask the ports tree for extra dependencies,
provided some other dependency refers to the same
.Ev BASE_PKGPATH
.Po
see
.Xr bsd.port.mk 5
.Pc .
The rationale is that those libraries must already be present for
the package to build correctly, and thus be reachable through the
subset of dependencies that are not pure
.Ev RUN_DEPENDS .
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl A Ar arches
Register a list of architectures for which this package should install.
.Ar arches
is a comma-separated list of architectures.
Use
.Sq *
to mean any architecture (e.g., arch-independent packages).
.It Fl B Ar pkg-destdir
Set
.Ar pkg-destdir
as the prefix to prepend to any file to select for the package.
.It Fl D Ar name Ns Op = Ns Ar value
Define
.Ar name
to
.Ar value
(or just define it)
for substitution and fragment inclusion purposes.
Some specific
.Ar names
have extra meaning, see
.Xr bsd.port.mk 5
for details:
.Pp
.Bl -tag -width FULLPKGPATH -compact
.It Ar CDROM
Set to the port's Makefile
.Ar PERMIT_PACKAGE_CDROM .
.It Ar COMMENT
Set package
.Dq one line description
(mandatory).
.It Ar HISTORY_DIR
Record checksums of files in permanent location
.Pa ${HISTORY_DIR}/${FULLPKGPATH:S,/,./g} .
.It Ar FTP
Set to the port's Makefile
.Ar PERMIT_PACKAGE_FTP .
.It Ar FULLPKGPATH
Strongly recommended, otherwise updates won't work.
.It Ar HOMEPAGE
If defined, appended to the description.
.It Ar MAINTAINER
If defined, appended to the description.
.It Ar USE_GROFF
Set to 1 to have groff format manpages behind the scenes during
package creation.
.El
.It Fl d No [-] Ns Ar desc
Fetch long description for package from file
.Ar desc
or, if preceded by
.Sq - ,
the argument itself.
.It Fl f Ar packinglist
Fetch
.Dq packing-list
for package from the file
.Ar packinglist .
Several packing-lists can be mentioned, in which case they will be
concatenated together.
.It Fl L Ar localbase
Record
.Ar localbase
as the localbase used in the package
.Po
By default,
.Pa /usr/local
.Pc .
Packages built with another localbase can only be installed by using
the same localbase in
.Xr pkg_add 1 ,
to prevent errors.
.It Fl M Ar displayfile
Display the file (using
.Xr more 1 )
after installing the package.
Useful for things like
legal notices on almost-free software, etc.
.It Fl m
Causes
.Nm
to always display the progress meter in cases it would not do so by default.
.It Fl n
Don't actually create a package.
.It Fl P Ar pkgpath : Ns Ar pkgspec : Ns Ar default
Declare a dependency on a package matching
.Ar pkgspec
.Pq see Xr packages-specs 7 .
An appropriate package must be installed before this package may be
installed, and that package must be deinstalled before this package
is deinstalled.
The dependency also contains a
.Ar pkgpath
.Po
see
.Xr pkgpath 7
.Pc
and a
.Ar default
package name, in case there is no listing of available packages.
.It Fl p Ar prefix
Set
.Ar prefix
as the initial directory
.Dq base
to start from in selecting files for
the package, and to record as the base for installing the package.
.It Fl Q
Print out the files in the actual packing-list of the package being
generated, with explicit typing
.Pq e.g. Cm @file , @lib , ... .
.It Fl q
Print out the actual packing-list of the package being generated
(query mode).
Most often used in combination with
.Fl n .
.It Fl s Ar signature-parameter
Specify signature parameters for signing packages on-the-fly during
building.
Refer to
.Xr pkg_sign 1
for the meaning of the parameters and the signing process.
.It Fl U Ar undisplayfile
Display the file (using
.Xr more 1 )
when deinstalling the package.
Useful for reminders about stuff to clean up.
.It Fl v
Turn on verbose output.
.It Fl W Ar libspec
Package needs a shared library to work.
.Ar libspec
is
.Sq name.major.minor
or
.Sq path/name.major.minor .
The package won't be installed unless a library with the same name,
the exact same major number and at least the same minor number can
be located.
A library without path is searched through dependent packages under the
same
.Ar localbase ,
then in the system libraries under
.Pa /usr/lib
and
.Pa /usr/X11R6/lib .
A library with a path is only searched through dependent packages,
that path being relative to
.Ar localbase .
.It Fl x
Disable progress meter.
.El
.Pp
.Nm
can also be invoked with only the packing-list from an installed package.
It will recreate the corresponding binary package in the current directory
from the installation, or error out if any problem is found.
For example,
the following will recreate a
.Pa kdelibs-3.4.3.tgz
package:
.Bd -literal -offset indent
pkg_create -f /var/db/pkg/kdelibs-3.4.3/+CONTENTS
.Ed
.Sh PACKING-LIST DETAILS
The
.Dq packing-list
format (see
.Fl f )
is fairly simple, being basically a list of filenames and directory names
to include in the package.
.Pp
Substitution of variables and inclusion of fragments is documented in the
next section.
.Pp
Directory names are denoted by a trailing slash.
.Pp
There are some annotations that can be inserted for better control.
All these commands start with an
.Sq @ .
The following annotations can be inserted manually:
.Pp
.Bl -tag -width Ds -compact
.It Cm @ask-update Ar pkgspec Ar message
Mechanism to prevent unwanted updates.
If the new package is installed as part of an update matching
.Ar pkgspec ,
the
.Ar message
will be displayed to the user.
In non-interactive mode, the update will abort.
Otherwise, the user will have a chance to proceed.
Automated updates can be done by using
.Fl D Ar update_stem ,
with
.Ar stem
the stem of the
.Ar pkgspec .
Classical use case for postgresql:
.Bd -literal -offset 3n
@ask-update postgresql-server-<8 Make sure your existing database is backed up
.Ed
.Pp
Use very sparingly.
Most cases that seem to require manual updates just require a bit more thought.
.Pp
.It Cm @bin Ar filename
Describe the file as an
.Ox
binary executable (not a script).
.Pp
.It Cm @comment Ar string
Place a comment in the packing-list.
Useful in trying to document some particularly hairy sequence that
may trip someone up later.
Can also be used to comment out elements that update-plist
.Pq see Xr bsd.port.mk 5
will insist in inserting in a packing-list.
.Pp
The special comment
.Cm @comment Ar "no checksum"
can be used to tag the next file as special: even though its characteristics
will be recorded in the package, it can be altered after installation, and
.Xr pkg_delete 1
will still delete it.
.Pp
.It Cm @conflict Ar pkgspec
Declare a conflict with packages matching
.Ar pkgspec
.Pq see Xr packages-specs 7 .
The
.Ar pkgname
package can
.Em not
be installed if a package
matching
.Ar pkgspec
has been installed because they install the same files and thus conflict.
.Pp
.It Cm @cwd Ar pathname
Set the package current directory.
All subsequent filenames will be assumed relative to
.Ar pathname .
.Pp
.It Cm @dir Ar directoryname
Create directory
.Ar directoryname
at
.Xr pkg_add 1
time, taking
.Cm @mode ,
.Cm @group ,
and
.Cm @owner
into account, and remove it during
.Xr pkg_delete 1 .
Directories to remove can be shared between packages.
If
.Ar name
does not begin with an @, same as
.Dl name/
.Pp
.It Cm @exec Ar command
Execute
.Ar command
during
.Xr pkg_add 1 .
Note that
.Cm @exec
commands are executed relative to their location in the packing-list,
so they can rely on any data that have already been extracted,
but not on anything that is listed after them.
Some special elements, such as new users and new groups, are always
created first, so that
.Cm @exec
can rely on them.
.Pp
.Xr pkg_add 1
and
.Xr pkg_delete 1
set the
.Ev PATH
to a predictable value:
.Bd -literal -offset indent
/bin:/sbin:/usr/bin:/usr/sbin:/usr/X11R6/bin:${LOCALBASE}/bin:${LOCALBASE}/sbin
.Ed
.Pp
during execution.
.Pp
If
.Ar command
contains any of the following sequences somewhere in it, they will
be expanded inline.
For the following examples, assume that
.Cm @cwd
is set to
.Pa /usr/local
and the last extracted file was
.Pa bin/emacs .
.Bl -tag -width indent
.It Cm "\&%B"
Expands to the
.Dq basename
of the fully qualified filename, that
is the current directory prefix, plus the last filespec, minus
the trailing filename.
In the example case, that would be
.Pa /usr/local/bin .
.It Cm "\&%D"
Expands to the current directory prefix, as set with
.Cm @cwd ;
in the example case
.Pa /usr/local .
.It Cm "\&%F"
Expands to the last filename extracted (as specified); in the example case,
.Pa bin/emacs .
.It Cm "\&%f"
Expands to the
.Dq filename
part of the fully qualified name, or
the converse of
.Cm \&%B ;
in the example case,
.Pa emacs .
.El
.Pp
.It Cm @exec-always Ar command
Synonym of
.Cm @exec .
.Pp
.It Cm @exec-add Ar command
Similar to
.Cm @exec ,
except it only gets executed during new installations,
and not during updates.
.Pp
.It Cm @exec-update Ar command
Similar to
.Cm @exec ,
except it only gets executed during updates,
and not during new installations.
.Pp
.It Cm @extra Ar filename
Declare extra file
.Ar filename
to be deleted at deinstall time, if user sets the
.Fl c
option.
Those files are extra configuration files that are normally not deleted.
.Ar filename
can be an absolute path.
If
.Ar filename
ends with a slash, it is a directory.
.Pp
.It Cm @extraunexec Ar command
Extra
.Ar command
to execute when removing extra files.
.Pp
.It Cm @file Ar filename
Default annotation, to use if
.Ar filename
begins with @.
.Ar filename
is always a relative path, relative to the current
.Cm @cwd .
.Pp
.It Cm @fontdir Ar directoryname
Specialized version of
.Cm @dir ,
to handle font directories: create
.Pa font.alias
from
.Pa font.alias-*
fragments, execute
.Xr mkfontdir 1 ,
.Xr mkfontscale 1
and
.Xr fc-cache 1
when needed.
Delete extra files at
.Xr pkg_delete 1
time.
.Pp
.It Cm @group Ar group
Set default group ownership for all subsequently extracted files to
.Ar group .
Use without an arg to set back to default (extraction)
group ownership.
.Pp
.It Cm @info Ar filename
Specialized version of
.Cm @file ,
to handle GNU info files.
Automatically grab
.Ar filename Ns -*
chapter files, run
.Xr install-info 1
as needed.
.Pp
.It Cm @lib Ar filename
Specialized version of
.Cm @file ,
to handle shared libraries.
Satisfy LIB_DEPENDS and WANTLIB,
run
.Xr ldconfig 8
as needed.
See
.Sq VARIABLE SUBSTITUTION AND FRAGMENT INCLUSION
for some details.
.Pp
.It Cm @man Ar filename
Specialized version of
.Cm @file ,
to handle manual pages.
.Pp
.It Cm @mandir Ar directoryname
Specialized version of
.Cm @dir ,
to handle manual directories: instruct user to add/remove the
directory to
.Xr man.conf 5 ,
remove
.Xr apropos 1
database when needed.
.Pp
.It Cm @mode Ar mode
Set default permission for all subsequently extracted files to
.Ar mode .
Format is the same as that used by the
.Xr chmod 1
command.
Use without an arg to set back to default (extraction) permissions.
.Pp
.It Cm @newgroup Ar name : Ns Ar gid
During
.Xr pkg_add 1 ,
create a new group, using
.Xr groupadd 8 .
Happens before file and user creations.
.Ar gid
can be prefixed with a
.Sq !\&
to ensure group has the correct GID.
During
.Xr pkg_delete 1 ,
groups will be deleted if extra clean-up has been requested, and if
other installed packages don't list the same group.
.Pp
.It Xo
.Cm @newuser
.Sm off
.Ar name :
.Ar uid :
.Ar group :
.Ar loginclass :
.Ar comment :
.Ar home :
.Ar shell
.Sm on
.Xc
During
.Xr pkg_add 1 ,
create a new user.
Happens before any file creation.
All fields correspond to
.Xr useradd 8
parameters.
Some fields are optional and can be left empty.
If the user already exists, no action is taken.
Individual fields can be prefixed by a
.Sq !\&
to make sure an existing
user matches.
For instance, the directive
.Li @newuser foo:!42
will make sure user foo has UID 42.
During
.Xr pkg_delete 1 ,
users will be deleted if extra clean-up has been requested, and if
other installed packages don't list the same user.
.Pp
.It Cm @option Ar name
Effects vary depending on
.Ar name .
These are the user settable options
.Bl -tag -width indent
.It Ar always-update
By default,
.Xr pkg_add 1
uses some simplified information to decide whether an installed package
needs updating.
With this option, the package is updated whenever anything changes.
To be used sparingly, as this is more expensive.
.It Ar no-default-conflict
By default, a package conflicts with other versions of the same package.
With this option, the older package version will still be noticed, but the
installation will proceed anyway.
.El
.Pp
.It Cm @owner Ar user
Set default ownership for all subsequently extracted files to
.Ar user .
Use without an arg to set back to default (extraction)
ownership.
.Pp
.It Cm @pkgcfl Ar pkgcflname
Declare a conflict to the
.Ar pkgcflname
package.
The
.Ar pkgcflname
package must
.Em not
be installed if
.Ar pkgname
package gets installed because they install the same files and thus conflict.
.Ar pkgcflname
may use
.Xr fnmatch 3
wildcards.
Deprecated, use
.Cm @conflict
instead.
.Pp
.It Cm @pkgpath Ar pkgpath
Declare a secondary
.Ar pkgpath
for the package.
This is used for updates:
.Nm pkg_add
.Fl u
normally checks that the
.Ar pkgpath
embedded in the package corresponds to the old package,
to solve ambiguities when packages with similar names are involved.
When ports get renamed, or flavors change, extra
.Cm @pkgpath
annotations can help
.Nm pkg_add
get a sense of continuity.
Note that these
.Ar pkgpath
can take extra optional components, to allow the matching of several
flavors at once, and are order independent.
For instance,
.Bd -literal -offset indent
@pkgpath some/dir,f1,f2
.Ed
.Pp
and
.Bd -literal -offset indent
@pkgpath some/dir,f2,f2,f1
.Ed
.Pp
are equivalent.
.Bd -literal -offset indent
@pkgpath some/dir,f1[,f2,f3][,f4]
.Ed
.Pp
will match all pkgpaths to some/dir with flavor f1, and optionally f4, and
optionally both f2 and f3, e.g.,
.Ar some/dir,f1,f4 ,
.Ar some/dir,f1,f2,f3 ,
.Ar some/dir,f1,f2,f3,f4 ,
.Ar some/dir,f1
would match,
but
.Ar some/dir,f1,f5 ,
.Ar some/dir,f2,f3 ,
.Ar some/dir,f1,f2,f4
would not.
.Pp
Each binary package contains a set of pkgpaths: the primary pkgpath that
was used to build the package, recorded as
.Cm @comment Ar pkgpath=some/path ,
and secondary pkgpaths as recorded through
.Cm @pkgpath .
.Pp
In order for two packages to match, their primary pkgpaths must match, or
a secondary pkgpath must match the other package's primary pkgpath.
.Pp
.It Cm @rcscript Ar filename
Script for the
.Pa /etc/rc.d
framework.
Contrary to
.Cm @file ,
absolute paths are okay, e.g.,
.Bd -literal -offset indent
@rcscript ${RCDIR}/ballsd
.Ed
.Pp
In this case, performs an implicit
.Cm @cwd
to
.Pa ${RCDIR} .
.Pp
.It Cm @sample Ar filename
Last preceding
.Cm @file
item is a sample configuration file, to be copied to
.Ar filename
at
.Xr pkg_add 1
time and to be removed at
.Xr pkg_delete 1
time.
During installation, existing configuration files are untouched.
During deinstallation, configuration files are only removed if unchanged.
.Ar filename
can be an absolute path.
If
.Ar filename
ends with a slash,
it refers to a configuration directory instead.
.Pp
.It Cm @shell Ar filename
Specialized version of
.Cm @file ,
to handle shells.
See
.Xr shells 5 .
.Pp
.It Cm @sysctl Ar var Ns = Ns Ar val
.It Cm @sysctl Ar var Ns \*(Ge Ns Ar val
During
.Xr pkg_add 1 ,
check that
.Xr sysctl 8
variable
.Ar var
is set to exactly/at least a given value
.Ar val .
Adjust it otherwise.
.Pp
.It Cm @unexec Ar command
Execute
.Ar command
during
.Xr pkg_delete 1 .
.Ev PATH
and expansion of special
.Cm \&%
sequences are the same as for
.Cm @exec .
Note that
.Cm @unexec
commands are executed relative to their location in the packing-list,
so they cannot rely on any data that has already been deleted,
thus they should occur before the files they need to function.
Some special elements, such as new users and new groups, are always
deleted last, so that
.Cm @unexec
can rely on them.
.Pp
.It Cm @unexec-always Ar command
Synonym of
.Cm @unexec .
.Pp
.It Cm @unexec-delete Ar command
Similar to
.Cm @unexec ,
except it only gets executed during true deletions
and not while removing an old package during updates.
.Pp
.It Cm @unexec-update Ar command
Similar to
.Cm @unexec ,
except it only gets executed while removing an old package during updates,
and not during true deletions.
.El
.Pp
See
.Xr package 5
for other internal annotations that are automatically added by the
package tools.
.Sh VARIABLE SUBSTITUTION AND FRAGMENT INCLUSION
In packing-lists, installation, deinstallation and requirement scripts,
description and message files,
constructs like
.Li ${VAR}
will be replaced with the variable value, according to
.Fl D Ar name Ns = Ns Ar value
options.
.Pp
In particular, shared library versions should never be mentioned explicitly
in a packing-list.
Shared library
.Sq foo
will take its version number from
.Ev LIBfoo_VERSION .
The ports framework normally takes care of all details, see
.Ev SHARED_LIBS
in
.Xr bsd.port.mk 5 ,
not to be confused with
.Va SHARED_LIBS
later in this document.
.Pp
Constructs like
.Li %%VAR%%
and
.Li !%%VAR%%
trigger fragment inclusion.
If such a line is encountered in a packing-list, the corresponding variable
must be defined to 0 or 1.
If the variable's value is 1,
.Li %%VAR%%
will be replaced by the corresponding positive fragment, and
.Li !%%VAR%%
will be ignored.
If the variable's value is 0,
.Li %%VAR%%
will be ignored, and
.Li !%%VAR%%
will be replaced by the corresponding positive fragment.
.Pp
A fragment is an auxiliary packing-list file, whose name is derived from the
current packing-list, and the variable name
.Va VAR
triggering the inclusion:
.Pa pkg/PLIST
yields a positive fragment
.Pa pkg/PFRAG.VAR
and a negative fragment
.Pa pkg/PFRAG.no-VAR ,
.Pa pkg/PLIST-FOO
yields a positive fragment
.Pa pkg/PFRAG.VAR-foo
and a negative fragment
.Pa pkg/PFRAG.no-VAR-foo .
.Pp
Fragments can be included inside fragments, so that
.Li %%VAR2%%
inside
.Pa pkg/PFRAG.VAR
triggers the inclusion of
.Pa pkg/PFRAG.VAR2-VAR
and
.Li !%%VAR2%%
triggers the inclusion of
.Pa pkg/PFRAG.no-VAR2-VAR .
.Pp
If a positive or a negative fragment file does not exist, the corresponding
inclusion will be ignored.
However, if both the positive and negative fragment files do not exist,
.Nm
will error out, to make it easier to spot fragment names errors.
.Pp
Shared libraries no longer require any fragments, but can be included directly
in the final packing-list:
on an architecture without shared libraries,
.Li @lib lib/libfoo.so.${LIBfoo_VERSION}
will automatically devolve into
.Li lib/libfoo.a ,
if needed (e.g., for a port that builds both a shared library and a normal
library on a shared libraries architecture,
.Li @lib lib/libfoo.so.${LIBfoo_VERSION}
will simply vanish on non-shared architectures).
Extra copies living in other directories will be ignored
.Po
See the description of
.Ev SHARED_ONLY
and
.Ev NO_SHARED_LIBS
in
.Xr bsd.port.mk 5
.Pc .
.Pp
As a special historical exception, the variable
.Va SHARED_LIBS
still control the inclusion of fragments
.Pa PFRAG.shared
and
.Pa PFRAG.no-shared
through the lines
.Li %%SHARED%%
and
.Li !%%SHARED%% .
