# bsd.wx.mk - Support for wxWidgets based ports.
#
# Created by: Alejandro Pulver <alepulver@FreeBSD.org>
#
# Please view me with 4 column tabs!
#
# The following variables can be defined in a port that uses the wxWidgets
# library, contributed libraries, WxPython and/or more wxWidgets related
# components (with run and/or build dependencies). It can be used after and/or
# before bsd.port.pre.mk, but Python components will only work if Python
# variables (e.g. USE_PYTHON) are defined before it (this is a bsd.python.mk
# limitation), at least it is manually included.
# USE_WX		- Set to the list of wxWidgets versions that can be used by
#				  the port. The syntax allows the following elements:
#				  - Single version (e.g. "3.0").
#				  - Range of versions (e.g. "2.8-3.0"). Must be ascending.
#				  - Partial range: single version and upper (e.g. "2.8+").
#				  - Partial range: single version and lower (e.g. "-2.8").
#				  Multiple elements can be specified separated by spaces.
# USE_WX_NOT	- Set to the list of wxWidgets versions that can't be used by
#				  the port. In other words, it removes some versions from
#				  USE_WX. If the latter is not defined, it will have the value
#				  of all the possible versions. The syntax is like USE_WX.
# WX_COMPS		- Set to the list of wxWidgets components the port uses.
#				  Several components can be specified separated by spaces. By
#				  default it will have the value of "wx". Suffixes in the form
#				  ":xxx" may be added to the components to determine the
#				  dependency type.
#				  The available components are:
#				  wx			- The wxWidgets library.
#				  contrib		- The wxWidgets contributed libraries.
#				  python		- The wxWidgets API for Python.
#				  The available dependency types are:
#				  build			- Requires component for building.
#				  lib			- Requires component for building and running.
#				  run			- Requires component for running.
#				  If no suffix is present then "run" will be used for "python"
#				  and "lib" for others.
# WX_CONF_ARGS	- Set to "absolute" or "relative" if the port needs configure
#				  arguments in addition to the WX_CONFIG environment variable.
#				  It determines the type of parameters that have to be passed
#				  to the configure script. In the first case it adds
#				  "--with-wx-config=${WX_CONFIG}" (absolute path of
#				  WX_CONFIG), and in second one "--with-wx=${LOCALBASE}" plus
#				  "--with-wx-config=${WX_CONFIG:T} (prefix and name).
# WX_PREMK		- Define to determine version and define WX_CONFIG/WX_VERSION
#				  after <bsd.port.pre.mk> (in case the port needs to manually run
#				  the script).
# WX_UNICODE	- Define if the port needs the Unicode version of the
#				  wxWidgets library and/or contributed libraries.
#				  NOTE: this should NOT be used for ports that can be compiled
#				  with Unicode or not, but for the ones that require it.
# WANT_UNICODE	- Define if the port prefers Unicode, but doesn't require it.
# WANT_WX		- Set to "yes" or a valid single version (no ranges, etc).
#				  In both cases it will detect the installed wxWidgets
#				  components and add them to the variable HAVE_WX. If a
#				  version is selected, HAVE_WX will contain a list of
#				  components in the other case it will contain a list of
#				  "component-version" pairs (e.g. wx-2.8, contrib-2.8, etc).
#				  It has to be used before bsd.port.pre.mk.
# WANT_WX_VER	- Set to the prefered wxWidgets version for the port. It must
#				  be present in USE_WX or missing in USE_WX_NOT. This is
#				  overriden by the user variable WITH_WX_VER if set. It can
#				  contain multiple versions in order of preference (last ones
#				  are tried first).
#
# The following variables are intended for the user and can be defined in
# make.conf.
# WITH_UNICODE	- Define if you prefer the Unicode version when available.
# WITHOUT_UNICODE
#				- Define if you prefer the non Unicode version (this
#				  variable disables WITH_UNICODE and WANT_UNICODE).
# WITH_WX_VER	- Define to the list of prefered versions in reverse order.
#
# The following variables are defined by this file, to be read from the port.
# WX_CONFIG		- The path to the wx-config program (with different name).
# WXRC_CMD		- The path to the wxrc program (with different name).
# WX_VERSION	- The wxWidgets version that is going to be used.
# WX_UNICODE	- If this variable is not defined by the port (which means it
#				  requires the Unicode version of wxWidgets), it will be
#				  defined in the case the Unicode version is used (enabled by
#				  WITH_UNICODE or WANT_UNICODE).
# HAVE_WX		- The list of wxWidgets components installed, if WANT_WX was
#				  defined. The components will have version suffix if it was
#				  set to "yes".
#
# Examples:
# - A port that needs wxWidgets 2.8 and contributed libraries with Unicode.
#	USE_WX=		2.8
#	WX_COMPS=	wx contrib
#	WX_UNICODE=	yes
# - A port that needs WxPython 2.8 for running.
#	USE_PYTHON=	yes
#	USE_WX=		2.8
#	WX_COMPS=	python:run
# - A port that needs WxPython 2.8 or 3.0 for building.
#	USE_PYTHON=	yes
#	USE_WX=		2.8 3.0
#	WX_COMPS=	python:build
# - A port that needs wxWidgets version 2.8 or higher and contributed
#	libraries.
#	USE_WX=		2.8+
#	WX_COMPS=	wx contrib
# - A port that needs wxWidgets of any version other than 2.8.
#	USE_WX_NOT=	2.8
