Hello world with LUA

Http://lua.gts-stolberg.de/en/LuaInC1.php

 

For those, who will not only use LUA for their game, I wowould like to show some possibilties to integrate lua in C.

The most simple way to embed Lua in C.

Integration of libraries

    #pragma comment(lib, "lib/lua")
#pragma comment(lib, "lib/lualib")

Header-Files

extern "C"
    {
        #include "include/lua.h"
        #include "include/lualib.h"
        #include "include/lauxlib.h"
    }

Creation of an instance.

lua_State* L;

int main(int argc, char* argv[])
    {

Open Lua.

        L = lua_open();

Open required libraries. For our Hello we only need the base-library and the IO-libraries. 

        luaopen_base(L);
// luaopen_string(L);
// luaopen_table(L);
// luaopen_math(L);
// luaopen_debug(L);
        luaopen_io(L);

Execute Lua-File

        lua_dofile(L,"my.lua");

Closing Lua.

        lua_close(L);

Ready

return 0;
    }

Code of my. lua:

print("Hello from LUA")

 

Libraries and header can be downloaded here.

They are 7-zip archived. Shows the best compression ratio at the moment.

And then thus it shoshould look:

Complete Code:

#pragma comment(lib, "lib/lua")
#pragma comment(lib, "lib/lualib")

extern "C"
    {
        #include "include/lua.h"
        #include "include/lualib.h"
        #include "include/lauxlib.h"
    }

    lua_State* L;

int main(int argc, char* argv[])
    {
        L=lua_open();

        luaopen_base(L);
// luaopen_string(L);
// luaopen_table(L);
// luaopen_math(L);
// luaopen_debug(L);
        luaopen_io(L);

        lua_dofile(L,"my.lua");

        lua_close(L);
return 0;
    }
