Re: The current state of interfacing Lua with C++ code

[Asko Kauppi <askok@...>]

I ended up doing our own binding (not open source, at least for now -  
sorry).

One of the benefits it has is integration of C++ 'new' operation with  
Lua object lifespan control. So doing

	new(L) MyClass( anything );

..calls the 'MyClass' constructor (of any type) but allocates the  
object in the Lua gc'ed memory area.

If there is a publically available C++/Lua binding library using the  
same mechanism, I'd be glad to know (it would be better to use a  
public library for the binding - or maybe I should push the customer  
to open up that part of the code?).

btw, 'MyClass' needs to derive from 'LuaObject', if anyone starts  
wondering how the above could ever work.

I would warn you about SWIG - imho it's way too complex for the job at  
hand (when Lua is concerned).  I've tried to like it twice, and failed  
both times. :/
