Compile lua code, store bytecode then load and execute it http://stackoverflow.com/questions/8936369/compile-lua-code-store-bytecode-then-load-and-execute-it functions to read a file from disk and load it into the lua_State . Alternatively you can load the file yourself into a string.. into a string and use luaL_loadstring to load it into the lua_State . Both of these functions will emit return values and compiler.. for lua_load . If the compilation was successful the lua_State now has the compiled Lua chunk as a Lua function at the top..
