 .Nd contributed applications
 .Sh DESCRIPTION
 The
 .Fx
 Ports Collection
 offers a simple way to compile and install third party applications.
 It is also used to build packages, to be installed using
 .Xr pkg 8 .
 .Pp
 The ports tree, typically located at
 .Pa /usr/ports ,
 consists of subdirectories, one for each category; those in turn contain
 individual ports.
 Each port is a directory with metadata and patches necessary to make
 the original application source code compile and run on
 .Fx .
 Compiling an application is as simple as typing
 .Dq Li "make build"
 in the port directory.
 The
 .Pa Makefile
 automatically fetches the
 application source code, either from a local disk or the network, unpacks it,
 applies the patches, and compiles it.
 It also recursively handles dependencies \(em other pieces of software
 the port depends on in order to build and work.
 Afterwards,
 .Dq Li "make install"
 installs the application.
 .Pp
 The
 .Fx
 Ports Collection is maintained in several branches, which differ mostly
 by versions of software provided: the
 .Em main
 branch contains all the latest changes and corresponds to the
 .Em latest
 package set, while the
 .Em quarterly
 branches only provide critical fixes.
 The
 .Em main
 branch can be cloned and updated from the Git repository located at:
 .Pp
 .Lk https://git.FreeBSD.org/ports.git
 .Pp
 so eg:
 .Pp
 .Cm git clone https://git.FreeBSD.org/ports.git
 .Pp
 The
 .Em quarterly
 branches can be found in Git as branches like
 .Pa yyyyQn
 , where
 .Em yyyy
 indicates the year and
 .Em n
 indicates the quarter
 .Po 1 to 4
 .Pc , eg:
 .Pp
 .Cm git clone -b 2021Q2 https://git.FreeBSD.org/ports.git
 .Pp
 It is generally a good idea to use the
 .Nm
 branch that matches the
 .Xr pkg 8
 repository being used.
 By default, for
 .Fx CURRENT
 the
 .Xr pkg 8
 is configured to install packages built from the
 .Em main
 branch, while for
 .Fx STABLE
 or RELEASE versions it is configured to install packages built from
 the latest
 .Em quarterly
 branch.
 Currently configured
 .Xr pkg 8
 repository can be verified by looking at the
 .Em url
 field in
 .Cm pkg -vv
 output.

 .Sh TARGETS
 Some of the
 .Xr make 1
 targets work recursively through subdirectories.
 This lets you, for example, install all of the
 .Dq Li biology
 ports with one command.
 The targets that do this are
 .Cm build , checksum , clean , configure ,
 .Cm depends , extract , fetch , install ,
 and
 .Cm package .
 .Pp
 The following targets will be run automatically by each proceeding
 target in order.
 That is,
 .Cm build
 will be run (if necessary) by
 .Cm install ,
 and so on all the way to
 .Cm fetch .
 Usually, you will only use the
 .Cm install
 target.
 .Bl -tag -width ".Cm configure"
 .It Cm config
 Configure
 .Va OPTIONS
 for this port using
 .Xr dialog4ports 1 .
 .It Cm fetch
 Fetch all of the files needed to build this port from the sites
 listed in
 .Va MASTER_SITES
 and
 .Va PATCH_SITES .
 See
 .Va FETCH_CMD , MASTER_SITE_OVERRIDE
 and
 .Va MASTER_SITE_BACKUP .
 .It Cm checksum
 Verify that the fetched distfile's checksum matches the one the port was
 tested against.
 If the distfile's checksum does not match, it also fetches the distfiles
 which are missing or failed the checksum calculation.
 Defining
 .Va NO_CHECKSUM
 will skip this step.
 .It Cm depends
 Install
 (or compile if only compilation is necessary)
 any dependencies of the current port.
 When called by the
 .Cm extract
 or
 .Cm fetch
 targets, this is run in piecemeal as
 .Cm fetch-depends , build-depends ,
 etc.
 Defining
 .Va NO_DEPENDS
 will skip this step.
 .It Cm extract
 Expand the distfile into a work directory.
 .It Cm patch
 Apply any patches that are necessary for the port.
 .It Cm configure
 Configure the port.
 Some ports will ask you questions during this stage.
 See
 .Va INTERACTIVE
 and
 .Va BATCH .
 .It Cm build
 Build the port.
 This is the same as calling the
 .Cm all
 target.
 .It Cm install
 Install the port and register it with the package system.
 This is all you really need to do.
 .It Cm install-missing-packages
 Install missing dependencies from packages instead of building them.
 .El
 .Pp
 The following targets are not run during the normal install process.
 .Bl -tag -width ".Cm fetch-recursive"
 .It Cm showconfig
 Display
 .Va OPTIONS
 config for this port.
 .It Cm showconfig-recursive
 Display
 .Va OPTIONS
 config for this port and all its dependencies.
 .It Cm rmconfig
 Remove
 .Va OPTIONS
 config for this port.
 .It Cm rmconfig-recursive
 Remove
 .Va OPTIONS
 config for this port and all its dependencies.
 .It Cm config-conditional
 Skip the ports which have already had their
 .Va OPTIONS
 configured.
 .It Cm config-recursive
 Configure
 .Va OPTIONS
 for this port and all its dependencies using
 .Xr dialog4ports 1 .
 .It Cm fetch-list
 Show list of files to be fetched in order to build the port.
 .It Cm fetch-recursive
 Fetch the distfiles of the port and all its dependencies.
 .It Cm fetch-recursive-list
 Show list of files that would be retrieved by
 .Cm fetch-recursive .
 .It Cm run-depends-list , build-depends-list
 Print a list of all the compile and run dependencies, and dependencies
 of those dependencies, by port directory.
 .It Cm all-depends-list
 Print a list of all dependencies for the port.
 .It Cm pretty-print-run-depends-list , pretty-print-build-depends-list
 Print a list of all the compile and run dependencies, and dependencies
 of those dependencies, by port name and version.
 .It Cm missing
 Print a list of missing dependencies to be installed for the port.
 .It Cm clean
 Remove the expanded source code.
 This recurses to dependencies unless
 .Va NOCLEANDEPENDS
 is defined.
 .It Cm distclean
 Remove the port's distfiles and perform the
 .Cm clean
 target.
 The
 .Cm clean
 portion recurses to dependencies unless
 .Va NOCLEANDEPENDS
 is defined, but the
 .Cm distclean
 portion never recurses
 (this is perhaps a bug).
 .It Cm reinstall
 Use this to restore a port after using
 .Xr pkg-delete 8
 when you should have used
 .Cm deinstall .
 .It Cm deinstall
 Remove an installed port from the system, similar to
 .Xr pkg-delete 8 .
 .It Cm deinstall-all
 Remove all installed ports with the same
 .Va PKGORIGIN
 from the system.
 .It Cm package
 Make a binary package for the port.
 The port will be installed if it has not already been.
 The package is a
-.Pa .txz
+.Pa .pkg
 file that you can use to
 install the port on other machines with
 .Xr pkg-add 8 .
 If the directory specified by
 .Va PACKAGES
 does not exist, the package will be put in
 .Pa /usr/ports/category/port/work/pkg .
 See
 .Va PKGREPOSITORY
 and
 .Va PKGFILE
 for more information.
 .It Cm package-recursive
 Like
 .Cm package ,
 but makes a package for each depending port as well.
 .It Cm package-name
 Prints the name with version of the port.
 .It Cm readmes
 Create a port's
 .Pa README.html .
 This can be used from
 .Pa /usr/ports
 to create a browsable web of all ports on your system!
 .It Cm search
 Search the
 .Pa INDEX
 file for the pattern specified by the
 .Va key
 (searches the port name, comment, and dependencies),
 .Va name
 (searches the port name only),
 .Va path
 (searches the port path),
 .Va info
 (searches the port info),
 .Va maint
 (searches the port maintainer),
 .Va cat
 (searches the port category),
 .Va bdeps
 (searches the port build-time dependency),
 .Va rdeps
 (searches the port run-time dependency),
 .Va www
 (searches the port web site)
 .Xr make 1
 variables, and their exclusion counterparts:
 .Va xname , xkey
 etc.
 For example, one would type:
 .Pp
 .Dl "cd /usr/ports && make search name=query"
 .Pp
 to find all ports whose
 name matches
 .Dq Li query .
 Results include the matching ports' path, comment, maintainer,
 build dependencies, and run dependencies.
 .Bd -literal -offset indent
 cd /usr/ports && make search name=pear- \e
     xbdeps=apache
 .Ed
 .Pp
 To find all ports whose
 names contain
 .Dq Li pear-
 and which do not have apache
 listed in build-time dependencies.
 .Bd -literal -offset indent
 cd /usr/ports && make search name=pear- \e
     xname='ht(tp|ml)'
 .Ed
 .Pp
 To find all ports whose names contain
 .Dq Li pear- ,
 but not
 .Dq Li html
 or
 .Dq Li http .
 .Bd -literal -offset indent
 make search key=apache display=name,path,info keylim=1
 .Ed
 .Pp
 To find ports that contain
 .Dq Li apache
 in either of the name, path, info
 fields, ignore the rest of the record.
 .Pp
 By default the search is not case-sensitive.
 In order to make it case-sensitive you can use the
 .Va icase
 variable:
 .Bd -literal -offset indent
 make search name=p5-R icase=0
 .Ed
 .It Cm quicksearch
 Reduced
 .Cm search
 output.
 Only display name, path and info.
 .It Cm describe
 Generate a one-line description of each port for use in the
 .Pa INDEX
 file.
 .It Cm maintainer
 Display the port maintainer's email address.
 .It Cm index
 Create
 .Pa /usr/ports/INDEX ,
 which is used by the
 .Cm pretty-print-*
 and
 .Cm search
 targets.
 Running the
 .Cm index
 target will ensure your
 .Pa INDEX
 file is up to date with your ports tree.
 .It Cm fetchindex
 Fetch the
 .Pa INDEX
 file from the
 .Fx
 cluster.
 .El
 .Sh ENVIRONMENT
 You can change all of these.
 .Bl -tag -width ".Va MASTER_SITES"
 .It Va PORTSDIR
 Location of the ports tree.
 This is
 .Pa /usr/ports
 by default.
 .It Va WRKDIRPREFIX
 Where to create any temporary files.
 Useful if
 .Va PORTSDIR
 is read-only (perhaps mounted from a CD-ROM).
 .It Va DISTDIR
 Where to find/put distfiles, normally
 .Pa distfiles/
 in
 .Va PORTSDIR .
 .It Va SU_CMD
 Command used to elevate privilege to configure and install a port.
 The unprivileged user must have write access to
 .Va WRKDIRPREFIX
 and
 .Va DISTDIR .
 The default is
 .Ql /usr/bin/su root -c .
 Many users set it to
 .Ql /usr/local/bin/sudo -E sh -c
 for convenience.
 .It Va PACKAGES
 Used only for the
 .Cm package
 target; the base directory for the packages tree, normally
 .Pa packages/
 in
 .Va PORTSDIR .
 If this directory exists, the package tree will be (partially) constructed.
 This directory does not have to exist; if it does not, packages will be
 placed into the current directory, or you can define one of
 .Bl -tag -width ".Va PKGREPOSITORY"
 .It Va PKGREPOSITORY
 Directory to put the package in.
 .It Va PKGFILE
 The full path to the package.
 .El
 .It Va LOCALBASE
 Where existing things are installed and where to search for files when
 resolving dependencies (usually
 .Pa /usr/local ) .
 .It Va PREFIX
 Where to install this port (usually set to the same as
 .Va LOCALBASE ) .
 .It Va MASTER_SITES
 Primary sites for distribution files if not found locally.
 .It Va PATCH_SITES
 Primary locations for distribution patch files if not found
 locally.
 .It Va MASTER_SITE_FREEBSD
 If set, go to the master
 .Fx
 site for all files.
 .It Va MASTER_SITE_OVERRIDE
 Try going to these sites for all files and patches, first.
 .It Va MASTER_SITE_BACKUP
 Try going to these sites for all files and patches, last.
 .It Va RANDOMIZE_MASTER_SITES
 Try the download locations in a random order.
 .It Va MASTER_SORT
 Sort the download locations according to user supplied pattern.
 Example:
 .Dl .dk .sunet.se .se dk.php.net .no .de heanet.dl.sourceforge.net
 .It Va MASTER_SITE_INDEX
 Where to get
 .Pa INDEX
 source built on
 .Fx
 cluster (for
 .Cm fetchindex
 target).
 Defaults to
 .Pa https://www.FreeBSD.org/ports/ .
 .It Va FETCHINDEX
 Command to get
 .Pa INDEX
 (for
 .Cm fetchindex
 target).
 Defaults to
 .Dq Li "fetch -am" .
 .It Va NOCLEANDEPENDS
 If defined, do not let
 .Cm clean
 recurse to dependencies.
 .It Va FETCH_CMD
 Command to use to fetch files.
 Normally
 .Xr fetch 1 .
 .It Va FORCE_PKG_REGISTER
 If set, overwrite any existing package registration on the system.
 .It Va INTERACTIVE
 If defined, only operate on a port if it requires interaction.
 .It Va BATCH
 If defined, only operate on a port if it can be installed 100% automatically.
 .It Va DISABLE_VULNERABILITIES
 If defined, disable check for security vulnerabilities using
 .Xr pkg-audit 8
 when installing new ports.
 .It Va NO_IGNORE
 If defined, allow installation of ports marked as
 .Aq Va FORBIDDEN .
 The default behavior of the Ports framework is to abort when the
 installation of a forbidden port is attempted.
 Of course, these ports may not work as expected, but if you really know
 what you are doing and are sure about installing a forbidden port, then
 .Va NO_IGNORE
 lets you do it.
 .It Va NO_CHECKSUM
 If defined, skip verifying the port's checksum.
 .It Va TRYBROKEN
 If defined, attempt to build a port even if it is marked as
 .Aq Va BROKEN .
 .It Va PORT_DBDIR
 Directory where the results of configuring
 .Va OPTIONS
 are stored.
 Defaults to
 .Pa /var/db/ports .
 Each port where
 .Va OPTIONS
 have been configured will have a uniquely named sub-directory, containing a
 single file
 .Pa options .
 .El
 .Sh MAKE VARIABLES
 The following list provides a name and short description for many of the
 variables that are used when building ports.
 More information on these and other related variables may be found in
 .Pa ${PORTSDIR}/Mk/*
 and the
 .Fx
 Porter's Handbook.
 .Bl -tag -width "WITH_CCACHE_BUILD"
 .It Va WITH_DEBUG
 .Pq Vt bool
 If set, debugging symbols are installed for ports binaries.
 .It Va WITH_DEBUG_PORTS
 A list of origins for which to set
 .Va WITH_DEBUG .
 .It Va DEBUG_FLAGS
 .Pq Default: Ql -g
 Additional
 .Va CFLAGS
 to set when
 .Va WITH_DEBUG
 is set.
 .It Va WITH_CCACHE_BUILD
 .Pq Vt bool
 If set, enables the use of
 .Xr ccache 1
 for building ports.
 .It Va CCACHE_DIR
 Which directory to use for the
 .Xr ccache 1
 data.
 .El
 .Sh FILES
 .Bl -tag -width ".Pa /usr/ports/Mk/bsd.port.mk" -compact
 .It Pa /usr/ports
 The default ports directory.
 .It Pa /usr/ports/Mk/bsd.port.mk
 The big Kahuna.
 .El
 .Sh EXAMPLES
 .Bl -tag -width 0n
 .It Sy Example 1\&: No Building and Installing a Port
 .Pp
 The following command builds and installs Emacs.
 .Bd -literal -offset 2n
 .Li # Ic cd /usr/ports/editors/emacs
 .Li # Ic make install
 .Ed
 .It Sy Example 2\&: No Installing Dependencies with Xr pkg 8
 .Pp
 The following example shows how to build and install a port without having to
 build its dependencies.
 Instead, the dependencies are downloaded via
 .Xr pkg 8 .
 .Bd -literal -offset 2n
 .Li # Ic make install-missing-packages
 .Li # Ic make install
 .Ed
 .Pp
 It is especially useful, when the dependencies are costly
 in time and resources to build
 .Pq like Pa lang/rust .
 The drawback is that
 .Xr pkg 8
 offers only packages built with the default set of
 .Va OPTIONS .
 .It Sy Example 3\&: No Building a Non-Default Flavor of a Port
 .Pp
 The following command builds a non-default flavor of a port.
 (In this case
 .Pa devel/py-pip
 is going to be built with Python 3.7 support.)
 .Bd -literal -offset 2n
 .Li # Ic cd /usr/ports/devel/py-pip
 .Li # Ic env FLAVOR=py37 make build
 .Ed
 .It Sy Example 4\&: No Setting Ports Options via Xr make.conf 5
 .Pp
 The following lines present various ways of configuring ports options via
 .Xr make.conf 5
 (as an alternative to, e.g., running
 .Dq Li make config ) :
 .Bd -literal -offset 2n
 # Enable NLS for all ports unless configured otherwise
 # using the options dialog.
 OPTIONS_SET=		NLS
 # Disable DOCS for all ports overriding the options set
 # via the options dialog.
 OPTIONS_UNSET_FORCE=	DOCS
 # Disable DOCS and EXAMPLES for the shells/zsh port.
 shells_zsh_UNSET=	DOCS EXAMPLES
 .Ed
 .Pp
 These and other options-related variables are documented in
 .Pa /usr/ports/Mk/bsd.options.mk .
 .It Sy Example 5\&: No Setting Xr make 1 Variables for Specific Ports via Xr make.conf 5
 .Pp
 The following example shows how to set arbitrary
 .Xr make 1
 variables only specific ports:
 .Bd -literal -offset 2n
 # Set DISABLE_MAKE_JOBS for the lang/rust port:
 \&.if ${.CURDIR:M*/lang/rust}
 DISABLE_MAKE_JOBS=	yes
 TRYBROKEN=		yes
 \&.endif
 .Ed
 .It Sy Example 6\&: No Debugging Ports
 By default ports are built and packaged without debugging support (e.g.,
 debugging symbols are stripped from binaries, optimization flags are used for
 compiling, verbose logging is disabled).
 Whether ports are built with debugging symbols can be controlled by the
 settings in
 .Xr make.conf 5 ,
 e.g.,
 .Bd -literal -offset 2n
 # Enable debugging for all ports.
 WITH_DEBUG=		yes
 # Enable debugging for selected ports.
 WITH_DEBUG_PORTS=	mail/dovecot security/krb5
 .Ed
 .Pp
 It is also possible to use the debug variables on the command line:
 .Bd -literal -offset 2n
 .Li # Ic make -DWITH_DEBUG DEBUG_FLAGS="-g -O0" build
 .Ed
 .Pp
 See the
 .Sx MAKE VARIABLES
 section to learn more about the debug variables.
 .Pp
 To understand the details of what happens when the debug variables are set it
 is best to consult the files located at
 .Pa ${PORTSDIR}/Mk/*
 .Po Pa bsd.port.mk
 in particular
 .Pc .
 .Pp
 If debugging is enabled for a specific port, the ports framework will:
 .Bl -bullet
 .It
 Add
 .Va DEBUG_FLAGS
 (defaults to
 .Ql -g )
 to
 .Va CFLAGS .
 .It
 Try to prevent the binaries from being stripped (including checking the install
 target to replace
 .Ql install-strip
 with
 .Ql install ) .
 Whether a binary has been stripped can be checked with
 .Xr file 1 .
 .It
 Try to enable other debugging features like debug build type or verbose logging.
 However, this is port-specific and the ports framework might not be aware of
 each supported debugging feature a given piece of software has to offer).
