RE: Lua and Objects

["Peter Prade" <prade@...>]

tolua (http://www.tecgraf.puc-rio.br/~celes/tolua) is perfect for this...

it automatically creates wrapper functions around your class methods...

if you don't like tolua, you can still have a look at the code that tolua
creates and do something similar.

Cheers,
Peter

Subject: Lua and Objects


Hi!

I'm sure that this question has been asked a few times. But bare with me :o)

In Lua I want to write something similar to this:

i = myExposedObject:someFunction( x )

In C++ I want to do something similar to:

static int someFunction( lua_State *L )
{
	object = (CppClass *) lua_popSelf( L ); // Insert correct function
here

	result = object->someFunctionImplementation();
	lua_pushnumber( L, result );

	return 1;
}

void main()
{
	CppClass exposedObject;

	// ....
	lua_register( L, "someFunction", someFunction );
	lua_setglobal( "myExposedObject", &exposedObject ); // Insert
correct function here
	// ....

	lua_dobuffer( ...... );

	// ....
}

Please help me out!
