# bsd.lua.mk - Support for Lua 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 Lua library,
# tolua, Ruby bindings or related components like .lua modules (with run
# and/or build dependencies). It can be used after and/or before
# bsd.port.pre.mk, but Ruby components will only work if Ruby variables (e.g.
# USE_RUBY) are defined before it (this is a bsd.ruby.mk limitation), at least
# it is manually included.
# USE_LUA		- Set to the list of Lua versions that can be used by the
#				  port. The syntax allows the following elements:
#				  - Single version (e.g. "4.0").
#				  - Range of versions (e.g. "5.0-5.1"). Must be ascending.
#				  - Partial range: single version and upper (e.g. "5.0+").
#				  - Partial range: single version and lower (e.g. "5.1-").
#				  Multiple elements can be specified separated by spaces.
# USE_LUA_NOT	- Set to the list of Lua versions that can't be used by the
#				  port. In other words, it removes some versions from USE_LUA.
#				  If the latter is not defined, it will have the value of all
#				  the possible versions. The syntax is like USE_LUA.
# LUA_COMPS		- Set to the list of Lua components the port uses. Several
#				  components can be specified separated by spaces. By default
#				  it will have the value of "lua". Suffixes in the form ":xxx"
#				  may be added to the components to determine the dependency
#				  type.
#				  The available components are:
#				  lua			- The Lua library.
#				  tolua			- The tolua library (for 4.0-5.1).
#				  toluaxx		- The tolua++ library (for 5.0-5.1).
#				  ruby			- The Ruby bindings for Lua (for 4.0-5.0).
#				  Other components (modules):
#				  5.0			- app, compat51, dfui, filename, gettext,
#								  posix, pty, socket.
#				  5.1			- alien, filename, gettext, posix, pty, socket.
#				  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 "lib" will be used for "lua"
#				  4.0-5.0 and "ruby", "build" for lua 5.1 and "tolua" (they
#				  are static), all others default to "run".
# LUA_PREMK		- Define to determine version and define variables after
#				  <bsd.port.pre.mk> (in case the port needs to manually run
#				  the Lua program or the like).
# WANT_LUA		- Set to "yes" or a valid single version (no ranges, etc).
#				  In both cases it will detect the installed Lua components
#				  and add them to the variable HAVE_LUA. If a version is
#				  selected, HAVE_LUA will contain a list of components in the
#				  other case it will contain a list of "component-version"
#				  pairs (e.g. lua-4.0, tolua-5.1, etc).
#				  It has to be used before bsd.port.pre.mk.
# WANT_LUA_VER	- Set to the prefered Lua version for the port. It must be
#				  present in USE_LUA or missing in USE_LUA_NOT. This is
#				  overriden by the user variable WITH_LUA_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_LUA_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.
# HAVE_LUA		- The list of Lua components installed, if WANT_LUA was
#				  defined. The components will have version suffix if it was
#				  set to "yes".
# LUA_VER		- The Lua version that is going to be used (e.g. "5.1").
# LUA_VER_SH	- The Lua shared library major version (e.g. "1").
# LUA_VER_STR	- The Lua version without the dots (e.g. "51").
# LUA_PREFIX	- The prefix where Lua (and components) is installed.
#				  NOTE: please see comments below about its double function.
# LUA_SUBDIR	- The directory under bin/share/lib where Lua is installed.
#				  Also used by Lua ports (lang/lua*) to set LATEST_LINK.
# LUA_INCDIR	- The directory where Lua, tolua and tolua++ header files are
#				  installed.
# LUA_LIBDIR	- The directory where Lua, tolua and tolua++ libraries are
#				  installed.
# LUA_MODLIBDIR	- The directory where Lua module libraries (.so) are installed.
# LUA_MODSHAREDIR
#				- The directory where Lua modules (.lua) are installed.
# LUA_PKGNAMEPREFIX
#				- The package name prefix used by Lua modules.
# LUA_CMD		- The path to the Lua interpreter.
# LUAC_CMD		- The path to the Lua compiler.
# TOLUA_CMD		- The path to the tolua program.
# TOLUAXX_CMD	- The path to the tolua++ program.
#
# Examples:
# - A port that needs Lua 4.0 and tolua (also 4.0) libraries (lua for building
#	and running and tolua for building).
#	USE_LUA=	4.0
#	LUA_COMPS=	lua tolua
# - A port that needs Ruby bindings for Lua 5.0 for building and running.
#	USE_LUA=	5.0
#	LUA_COMPS=	ruby
# - A port that needs tolua 5.0 or 5.1 for building.
#	USE_LUA=	5.0 5.1
#	LUA_COMPS=	tolua
# - A port that needs Lua version 5.0 or higher for building and running.
#	USE_LUA=	5.0+
# - A port that needs Lua of any version other than 5.1 for building and
#	running.
#	USE_LUA_NOT=5.1
#
# Notes about the integration of lua related ports with bsd.lua.mk:
# (please read when updating ports referred here, see lang/lua[0-9]*)
#
# The lua/tolua ports have to be patched so they can coexist, as the internal
# application build infrastructure does not handle it automatically. Currently
# the framework provides variables to the lua ports themselves, so changing
# some things here won't require changes in lang/{lua,tolua}*.
#
# For lua ports: if they install a static library, use the same method for
# tolua ports, otherwise in addition the libraries have to be symlinked to the
# common library directory with a versioned name, and linked with the -soname
# parameter (so when a port links with -L/usr/local/lib/lua51 -llua, it stores
# the dynamic dependency as the name which figures under /usr/local/lib).
#
# For tolua ports: as it is a static library (.a), installing binaries,
# headers and libraries under a versioned directory is fine (binary has also a
# symlink).
#
# The lua modules install in a separate directory, so there is no problem.
