NAME
----
portgroup - MacPorts PortGroup command reference

SYNOPSIS
--------
[cmdsynopsis]
PortGroup gnustep 1.0
PortGroup perl5 1.0
PortGroup python24 1.0
PortGroup python25 1.0
PortGroup python30 1.0

DESCRIPTION
-----------
MacPorts defines the notion of PortGroup classes with the PortGroup command.
These classes factorize the work for similar ports. Port maintainers willing
to use PortGroup need to have some notion of Portfiles. See man:portfile[7].

XCODE PORTGROUP
---------------
*PortGroup xcode* is here to easily port Xcode-based opensource software. It
handles configuration, build and destroot phases. It also defines some values
for Xcode-based software. A minimum Portfile using the *xcode PortGroup* class
only defines the fetch and the checksum phases.

Using *PortGroup xcode* is a way to make your port more robust to Xcode version
updates as the PortGroup is tested against all supported Mac OS X and Xcode
versions.

XCODE PORTGROUP SUGAR
~~~~~~~~~~~~~~~~~~~~~

Portfiles using *xcode PortGroup* do not need to define the following variables:

categories::
    *Default:* aqua

platforms::
    *Default:* macosx

use_configure::
    *Default:* no

Moreover, Portfiles using *PortGroup xcode* do not need to define any build or
destroot phase. Some options are provided for tailoring these phases to what the
software requires.

XCODE PORTGROUP SPECIFIC VARIABLES
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Portfiles using *xcode PortGroup* may define the following variables:

xcode.project::
    Path (relative to ${build.dir} and ${destroot.dir}) of the Xcode
    project. If unset, let xcode tool figure it out. It usually succeeds if
    there is a single project in the directory.
+
--
*Type:*;; optional
--
+
*Example:*
+
--------
xcode.project ${name}.xcode
--------

xcode.configuration::
    Project configuration/buildstyle to use.
+
--
*Type:*;; optional
*Default:*;; Deployment
--
+
*Example:*
+
--------
xcode.configuration Main
--------

xcode.target::
    If present, overrides build.target and destroot.target.
    *Type:*;; optional

xcode.build.settings::
    Additional settings passed to the xcode build tool during the build phase.
    These settings should be in the X=Y form.
+
--
*Type:*;; optional
--
+
*Example:*
+
--------
xcode.build.settings FRAMEWORK_SEARCH_PATHS=${prefix}/Library/Frameworks
--------

xcode.destroot.type::
    Type of project that will be installed. This tells Xcode PortGroup how to
    destroot the project. Correct values are application and framework.
+
--
*Type:*;; optional
*Default:*;; application
--
+
*Example:*
+
--------
xcode.destroot.type framework
--------

xcode.destroot.path::
    Where to install the build product.
    *Type:*;; optional
    *Default:*;; $\{prefix\}/Library/Frameworks or /Applications/MacPorts depending on xcode.destroot.type

xcode.destroot.settings::
    Additional settings passed to the xcode build tool during the destroot
    phase. These settings should be in the X=Y form.
+
--
*Type:*;; optional
--
+
*Example:*
+
--------
xcode.destroot.settings SKIP_INSTALL=NO
--------


STANDARD PORTFILE VARIABLES AFFECTING XCODE PORTGROUP
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The following standard Portfile variables actually affect *xcode PortGroup*. In
most cases, you will not need to set any of these variables in the Portfile.

destroot::
    Where to destroot the project.

build.cmd::
    The command to invoke to build the project. *xcode PortGroup* sets this
    variable to $\{xcodebuildcmd\}.

build.target::
    The Xcode target to build. *xcode PortGroup* sets this variable to "", thus
    building all targets. This variable will be ignored if xcode.target is set.

build.pre_args::
    Additional parameters for ${build.cmd}.
    *Default:*;; none

build.args::
    Main parameters for ${build.cmd}.
    *Default:*;; build

build.post_args::
    Additional parameters for ${build.cmd}.
    *Default:*;; none

build.dir::
    Where to build the project from (i.e. where the Xcode project is).
    *Default:*;; $\{worksrcpath\}

destroot.cmd::
    The command to invoke to destroot the project. *xcode PortGroup* sets this
    variable to xcodebuildcmd.

destroot.target::
    The Xcode target to install. *xcode PortGroup* sets this variable to "",
    thus installing all targets. This variable will be ignored if xcode.target
    is set.

destroot.pre_args::
    Additional parameters for ${destroot.cmd}.
    *Default:*;; none

destroot.args::
    Main parameters for ${destroot.cmd}.
    *Default:*;; install

destroot.post_args::
    Additional parameters for ${destroot.cmd}.
    *Default:*;; none

destroot.dir::
    Where to destroot the project from (i.e. where the Xcode project is).
    *Default:*;; $\{worksrcpath\}

GNUSTEP PORTGROUP
-----------------
*PortGroup gnustep* is here to easily port GNUstep-based opensource software
using the GNU objective- C runtime. It handles configuration, build and destroot
phases. It also defines some values for GNUstep-based software. A minimum
Portfile using the *gnustep PortGroup* class only defines the fetch and the
checksum phases.

GNUSTEP FILESYSTEM LAYOUTS
~~~~~~~~~~~~~~~~~~~~~~~~~~
PortGroup gnustep also supports both the traditionnal gnustep file layout and
the new fhs file layout. However, the ports themselves do not necessarily
support both. The Portfiles have access to many procedures in dealing with these
two layouts:

set_gnustep_make::
    Sets GNUSTEP_MAKEFILES according to the FilesystemLayout

set_gnustep_env::
    Sets DYLD_LIBRARY_PATH and PATH for the gnustep FilesystemLayout

gnustep_layout::
    Returns true (1) if current file layout is gnustep

set_system_library::
    Sets GNUSTEP_SYSTEM_LIBRARY according to the FilesystemLayout

set_local_library::
    Sets GNUSTEP_LOCAL_LIBRARY according to the FilesystemLayout

GNUSTEP PORTGROUP SUGAR
~~~~~~~~~~~~~~~~~~~~~~~
Portfiles using *gnustep PortGroup* do not need to define the following variables:

categories::
    *Default:* gnustep

homepage::
    *Default:* http://www.gnustep.org/

master_sites::
    *Default:* gnustep:core

depends_lib::
    *Default:* gnustep-core

use_configure::
    *Default:* no

configure.env::
    *Default:* DYLD_LIBRARY_PATH PATH

configure.pre_args-append::
    *Default:* CC=gcc-mp-4.2 GNUSTEP_MAKEFILES

build.type::
    *Default:* gnu

build.env::
    *Default:* DYLD_LIBRARY_PATH PATH

build.pre_args-append::
    *Default:* messages=yes

destroot.env::
    *Default:* DYLD_LIBRARY_PATH PATH

destroot.pre_args-append::
    *Default:* messages=yes

Moreover, Portfiles using *PortGroup gnustep* do not need to define any build or
destroot phase. Some options are provided for tailoring these phases to what the
software requires. A mechanism is also provided to ease the patch process.

GNUSTEP PORTGROUP SPECIFIC VARIABLES 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Portfiles using *gnustep PortGroup* may define the following variables:

gnustep.post_flags::
    an associative array which specifies the sub-directories relative to
    $\{worksrcpath\} and the SHARED_LD_POSTFLAGS variables to be added to
    GNUmakefile.preamble in those sub-directories. This helps making the
    patching process easier on Darwin.
+
--
*Type:*;; optional

+
*Example:*
+
--------
platform darwin {
    array set gnustep.post_flags {
        BundleSubDir "-lfoo -lbar"
    }
}
--------

gnustep.cc::
+
--
*Type:*;; optional
*Default:*;; gcc-mp-4.2
--
+
*Example:*
+
--------
gnustep.cc gcc-mp-4.3
--------

variant with_docs::
    Many GNUstep packages include a Documentation sub-directory that is not
    built by default. Enabling this variant builds and installs the included
    documentation.
+
--
*Type:*;; optional
--
+
*Example:*
+
--------
port install gnustep-gui +with_docs
--------
