# Provide support for lua

# MAINTAINER: ports@FreeBSD.org
|
|
# Usage:
|
|
#
|
|
# USES+= lua[:options,...]
|
|
#
|
|
# Options:
|
|
#
|
|
# NN (e.g. 52) - specify an allowed Lua version (can use multiple times)
|
|
# NN+ (e.g. 52+) - specify a minimum Lua version (discouraged)
|
|
# -NN (e.g. -53) - specify a maximum allowed version
|
|
# NN-NN (e.g. 51-53) - specify a range of allowed versions
|
|
#
|
|
# flavors define FLAVOR / FLAVORS as luaNN from the allowed versions
|
|
#
|
|
# noflavors don't use flavors
|
|
#
|
|
# module (implies flavors) specifies that the port is a Lua module
|
|
# (i.e. that it installes files in MODLIBDIR etc.)
|
|
#
|
|
# build add dependency to BUILD_DEPENDS instead of LIB_DEPENDS
|
|
# run add dependency to RUN_DEPENDS instead of LIB_DEPENDS
|
|
#
|
|
# env define only the LUA_* vars and add them to PLIST_SUB and
|
|
# MAKE_ENV, do not add dependencies or other global state
|
|
#
|
|
# core for building Lua itself
|
|
#
|
|
# If more than one version is allowed, then the LUA_DEFAULT version (as set
|
|
# in DEFAULT_VERSIONS) is chosen if it is in the allowed range, otherwise
|
|
# the closest allowed version to the default is chosen, preferring the
|
|
# larger version in case of a tie.
|
|
#
|
|
# But if "flavors" was requested, and FLAVOR is set, we use that version
|
|
# exactly. (It is an error to specify a flavor that isn't supported, but
|
|
# that is checked in bsd.port.mk, not here.)
|
|
#
|
|
# LUA_FLAVOR is defined to the desired flavor whether or not "flavors" was
|
|
# selected; ports should use this to specify the flavor of dependencies
|
|
# which are Lua modules or otherwise Lua-flavored.
|
|
#
|
|
# It's not generally expected that applications that embed Lua, or apps
|
|
# written in Lua, would use USES=lua:flavors. Given that Lua is lightweight
|
|
# and does not carry around a whole lot of module ecosystem with it, it is
|
|
# best that application ports simply specify the Lua version or range of
|
|
# versions that they support, and let the default one or the latest one be
|
|
# used. However, they should still use LUA_FLAVOR as needed when specifying
|
|
# dependencies.
|
|
#
|
|
# We assume Lua versions can be represented as 2 digits.
