[Swig-user] SWIG Calling Script Language Functions (Lua, specifically)

[Eddie P. <ep...@fr...>]

Hello!

I hadn't considered this, but I saw a post somewhere that SWIG is a good 
alternative to binding C++ to Lua, versus luabind and tolua.  I've given 
this a try, and it does indeed seem easy to have Lua code access my C++ 
objects.

My question however, is whether it's possible to call Lua functions from 
C++.  Specifically to call them and pass them C++ objects, and have SWIG 
set the appropriate metatable while they transition.  This is important, 
especially if it can handle not only copy-by-value, but also by reference.

Anyhow, in reading the documentation, I couldn't find anything of the 
sort mentioned, and I'm curious if I'm missing something, or if anyone 
could give me a brief synopsis as to how I could achieve this using 
SWIG.  If I *have* missed some piece of documentation, feel free to 
scold me, but I'd still appreciate a pointer as to where to look!

Thanks in advance!
