.Sh NAME
.Nm ports
.Nd contributed applications
.Sh DESCRIPTION
The
.Ox
Ports Collection
(shamelessly stolen from the
.Fx
Ports Collection) offers a simple way
for users and administrators to install applications.
Each port contains any patches necessary to make the original
application source code compile and run on BSD.
Compiling an application is as simple as typing
.Ic make
in the port directory!
The
.Pa Makefile
automatically fetches the
application source code, either from a local disk or via ftp, unpacks it
on the local system, applies the patches, and compiles it.
If all goes well, simply type
.Ic sudo make install
to install the application.
.Pp
For more information about using ports, see
The
.Ox
Ports Mechanism
(http://www.openbsd.org/ports.html).
For information about creating new ports, see
.\" .Xr porting 7
.\" and
Building an
.Ox
Port (http://www.openbsd.org/porting.html).
Other excellent resources are the ports and porting sections of the
.Fx
Handbook (http://www.freebsd.org/handbook/ports.html and
http://www.freebsd.org/handbook/porting.html) as well as the
.Nx
Package System documentation
(http://www.netbsd.org/Documentation/netbsd/Packages.txt).
.Pp
For a detailed description of the build process, see
.Xr bsd.port.mk 5 .
.Sh PORTS MASTER MAKEFILE
The ports master Makefile, normally located in
.Pa /usr/ports/Makefile
(but see
.Ev PORTSDIR
below)
offers a few useful targets.
.Bl -tag -width configure
.It Ar index
rebuild the ports complete index,
.Pa /usr/ports/INDEX
.It Ar mirror-maker
see
.Xr mirroring-ports 7 ,
.It Ar print-index
display the contents of the index in a user-friendly way,
.It Ar search
invoked with a key, e.g.,
.Ic make search key=foo ,
retrieve information relevant to a given port (obsolescent).
.El
.Sh SELECTING A SET OF PORTS
If
.Pa /usr/ports/INDEX
is up to date, it is possible to select subsets by setting the following
variables on the command line:
.Bl -tag -width category
.It Va key
package name matching the given key,
.It Va category
port belonging to category,
.It Va maintainer
port maintained by a given person.
.El

For instance, to invoke clean on all ports in the x11 category, one can say:
.Bd -literal -offset indent
	make category=x11 clean
.Ed

The index search is done by a perl script, so all regular expressions from
.Xr perlre 1
apply.
.Sh TARGETS
Individual ports are controlled through a few documented targets.
Some of these targets work recursively through subdirectories, so that
someone can, for examples, install all of the net
ports.
.Pp
In case of failure in a subdirectory, the shell fragment held in
.Ev REPORT_PROBLEM
is executed.
Default behavior is to call exit, but this can be overridden on the command
line, e.g., to avoid stopping after each problem.
.Bd -literal -offset indent
	make REPORT_PROBLEM=true
.Ed

The targets that do this are
.Ar build , checksum , clean , configure , extract , fake, fetch ,
.Ar install , distclean , deinstall, reinstall, mirror-distfiles, obj ,
.Ar package , cdrom-packages , link-categories, unlink-categories ,
and
.Ar ftp-packages .
.Pp
Target names starting with _ are private to the ports infrastructure,
should not be invoked directly, and are liable to change without notice.
.Pp
In the following list, each target will run the preceding targets
in order automatically.
That is,
.Ar build
will be run
.Pq if necessary
by
.Ar install ,
and so on all the way to
.Ar fetch .
Typical use only runs
.Ar install
explicitly (if root or
.Ev SUDO
is defined in
.Pa /etc/mk.conf ) ,
or
.Ar build
(as user), then
.Ar install
(as root).
.Bl -tag -width configure
.It Ar fetch
Fetch all of the files needed to build this port from the site(s)
listed in
.Ev MASTER_SITES
and
.Ev PATCH_SITES .
See
.Ev FETCH_CMD
and
.Ev MASTER_SITE_OVERRIDE .
.It Ar checksum
Verify that the fetched distfile matches the one the port was tested against.
Defining
.Ev NO_CHECKSUM
to
.Dv Yes
will skip this step.
Sometimes, distfiles change without warning.
The main
.Ox
mirror should still hold a copy of old distfiles, indexed by checksum.
Using
.Bd -literal -offset indent
	make checksum REFETCH=true
.Ed

will try to get a set of distfiles that match the recorded checksum.
.It Ar depends
Install
.Pq or package if only compilation is necessary
any dependencies of the current port.
When called by the
.Ar extract, install
or
.Ar fetch
targets, this is run in scattered pieces as
.Ar fetch-depends , lib-depends , build-depends , run-depends
and
.Ar misc-depends .
Defining
.Ev NO_DEPENDS
to
.Dv Yes
will skip this step.
.It Ar extract
Expand the distfile into a work directory.
.It Ar patch
Apply any patches that are necessary for the port.
.It Ar configure
Configure the port.
Some ports will ask questions during this stage.
See
.Ev INTERACTIVE
and
.Ev BATCH .
.It Ar build
Build the port.
This is the same as calling the
.Ar all
target.
.It Ar fake
Pretend to install the port under a subdirectory of the work directory.
.It Ar package
Create a binary package from the fake installation.
The package is a .tgz file that can be used to
install the port on several machines with
.Xr pkg_add 1 .
.It Ar install
Install the resulting package.
.El
.Pp
The following targets are not run during the normal install process.
.Bl -tag -width fetch-list
.It Ar depends-list package-depends
Print an ordered list of all the compile and run dependencies.
.It Ar clean
Remove the expanded source code.
This does not recurse to dependencies unless
.Ev CLEANDEPENDS
is defined to
.Dv Yes .
.It Ar distclean
Remove the port's distfile(s) and perform the
.Ar clean
operation.
This does not recurse to dependencies.
.It Ar reinstall
Use this to restore a port after using
.Xr pkg_delete 1 .
.It Ar link-categories
Populate the ports tree with symbolic links for each category the port
belongs to.
.It Ar unlink-categories
Remove the symbolic links created by
.Ar link-categories .
.El
.Sh NETWORK CONFIGURATION
The variables pertaining to network access have been marshalled into
.Pa ${PORTSDIR}/infrastructure/template/network.conf.template .

To customize that setup, copy that file into
.Pa ${PORTSDIR}/infrastructure/db/network.conf
and edit it.
.Pp
.Bl -tag -width MASTER_SITES
.It Ev MASTER_SITE_OPENBSD
If set to
.Dv Yes ,
include the master
.Ox
site when fetching files.
.It Ev MASTER_SITE_FREEBSD
If set to
.Dv Yes ,
include the master
.Fx
site when fetching files.
.It Ev MASTER_SITE_OVERRIDE
Go to this site first for all files.
.El
.Sh PORT VARIABLES
These can be changed in the environment, or in
.Pa /etc/mk.conf
for persistence.
They can also be set on make's command line, e.g.,
.Ic make VAR_FOO=foo
.Pp
Boolean variables should be set to
.Dv Yes
instead of simply being defined, for uniformity and future compatibility.
.Pp
Variable names starting with _ are private to the ports infrastructure,
should not be changed by the user, and are liable to change without notice.
.Pp
.Bl -tag -width MASTER_SITES
.It Ev PORTSDIR
Location of the ports tree.
This is
.Pa /usr/ports
on
.Fx
and
.Ox
and
.Pa /usr/pkgsrc
on
.Nx .
.It Ev DISTDIR
Where to find/put distfiles, normally
.Pa distfiles/
in
.Ev PORTSDIR .
.It Ev PACKAGES
Used only for the
.Ar package
target; the base directory for the packages tree, normally
.Pa packages/${ARCH}
in
.Ev PORTSDIR .
If this directory exists, the package tree will be (partially) constructed.
This directory does not have to exist; if it doesn't, packages will be
placed into the current directory, or define one of
.Bl -tag -width PKGREPOSITORY
.It Ev PKGREPOSITORY
Directory to put the package in.
.It Ev PKGFILE
The full path to the package.
.El

locally.
.It Ev CLEANDEPENDS
If set to
.Dv Yes ,
let
.Sq clean
recurse to dependencies.
.It Ev NOCLEANDEPENDS
If defined, don't let
.Sq clean
recurse to dependencies (deprecated, use
.Ev CLEANDEPENDS
instead).
.It Ev FETCH_CMD

.Sh AUTHORS
This man page was originated by
David O'Brien, from the
.Fx
project.
.Sh HISTORY
.Nm The Ports Collection
appeared in
.Fx 1.0 .
It was introduced in
.Ox
by Ejovi Nuwere, with much initial effort by Angelos D. Keromytis.
Maintenance passed then to Marco S Hyman,
it is currently managed by Christopher Turan,
with much help from Marc Espie, Kevin Lo, Brad Smith, Christian Weisgerber,
and a host of others found at ports@openbsd.org.
.Sh BUGS
Ports documentation is split over several places ---
.Pa /usr/share/mk/bsd.port.mk ,
the
.Dq Ports Collection
section of the
.Fx
handbook, the
.Dq Porting Existing Software
section of the
.Fx
handbook,
and some man pages.
.Ox
adds a few web pages to further confuse the issue.
