3# Build rules and definitions for Lua modules

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