3# Build rules and definitions for Lua modules
4
5#
6# Variables used
7#
8# LUA_VERSION	currently installed version of Lua
9# LUA_LIBDIR	${LIBDIR}/lua/${LUA_VERSION}
10#
11# LUA_MODULES	list of Lua modules to build/installi
12# LUA_DPLIBS	shared library dependencies as per LIBDPLIBS
13#
14# LUA_SRCS.mod	sources for each module (by default: "${mod:S/./_/g}.lua")
15#
16# DPADD		additional dependencies for building modules
17# DPADD.mod	additional dependencies for a specific module
18#
19#
20# HAVE_LUAC	if defined, .lua source files will be compiled with ${LUAC}
21#		and installed as precompiled chunks for faster loading. Note
22#		that the luac file format is not yet standardised and may be
23#		subject to change.
24#
25# LUAC		the luac compiler (by default: /usr/bin/luac)
26#
27#
28# Notes:
29#
30# currently make(depend) and make(tags) do not support .lua sources; We
31# add Lua sources to DPSRCS when HAVE_LUAC is defined and other language
32# sources to SRCS for <bsd.dep.mk>.
33#
34# other language support for other than C is incomplete
35#
36# C language sources are passed though lint, when MKLINT != "no"
37#
38# The Lua binary searches /usr/share/lua/5.1/ at this time and we could
39# install .lua modules there which would mean slightly less duplication
40# in compat builds. However, MKSHARE=no would prevent such modules from
41# being installed so we just install everything under /usr/lib/lua/5.1/
