- Subject: RE: Calling a function in a table from C++ without loosing 'self'
- From: Alexander Marinov <alek@...>

I'm sorry if this response is useless or late, but I just wanted to test the mailing list.
test.c:
------------------------------
#include
const char m_TableName[]="GameObject";
main()
{
lua_State* VM=lua_open();
luaopen_base(VM);
lua_dofile(VM, "test.lua");
/* copied from your message ..*/
// first get the table
lua_pushstring(VM, m_TableName); // m_TableName = "GameObject" in this example
lua_gettable(VM, LUA_GLOBALSINDEX);
// get the 'init' function from the table
lua_pushstring(VM, "init");
lua_gettable(VM, -2);
// call the function
/* first arg is the self */
lua_pushstring(VM, m_TableName); // m_TableName = "GameObject" in this example
lua_gettable(VM, LUA_GLOBALSINDEX);
lua_call(VM, 1, 0);
return 0;
}
test.lua:
------------------------------
GameObject={_m="hi"};
function GameObject:init()
print(self._m);
end
result:
------------------
$cc -o test test.c -llualib -llua
$./test
