Call Lua string using C

Question

I'm trying to learn how to use Lua with C, so I want to try running the script without loading it from a file, since I don't want to worry about messing up the files. Can someone tell me which functions I need to call to execute a simple string or something else?

Answer 1

You can use luaL_dostring to execute a script from a string.

If you need help with the basics (creating Lua state, etc.), read Part IV, Programming in Lua .

Answer 2

Lua-, :

bool Reader::RunBuffer(const char *buff,char* ret_string,const char *name){
    int error = 0;
    char callname[256] = "";
    if( m_plua == NULL || buff == NULL || ret_string == NULL ) return false;
    if( name == NULL ){
        strcpy(callname,"noname");
    }else{
        strcpy(callname,name);
    }
    error = luaL_loadbuffer(m_plua, buff, strlen(buff),callname) || lua_pcall(m_plua, 0, 1, 0);
    if (error){
        fprintf(stderr, "%s\n", lua_tostring(m_plua, -1));
        lua_pop(m_plua, 1);
    }else{
        sprintf(ret_string, "%s", lua_tostring(m_plua, -1));
    }
    return true;
}
