      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/
