Synopsis

Tool for compiling Lua into bytecode using Garry's Mod's lua_shared dynamic library. Useful for obfuscation of source code you don't want readable.

Based on https://github.com/lua/luac/blob/master/luac.c and https://code.google.com/p/lcdhost/

Prerequisites

Depends on danielga/scanning which is included as a git submodule. And premake5 is used to create project files.

lua_dyn.c & lua_dyn.h are generated using tools/lua_dyn_export_h.lua alongside the source code for the target version of LuaJIT used in GMod (currently luajit-2.0.4)

Running the program requires the libraries from GMod to be in the directory with them:

• Windows: lua_shared.dll, tier0.dll and vstdlib.dll
• Linux: lua_shared_srv.so, libsteam.so, libsteam_api.so, libtier0_srv.so libvstdlib_srv.so

On Linux you need to export LD_LIBRARY_PATH to the directory in order to load the shared libraries from it, this can be done by simply running: export LD_LIBRARY_PATH=.

Building From Source

First run: git submodule update --init --recursive to grab danielga/scanning.

• Windows: Generate your project files using premake5 vs2015 and build using project/gluac.sln
• Linux: Run premake5 gmake && make
