Hello world with LUA

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

 

For those, who will not only use LUA for their game, I would 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 should 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;
    }
