I'd like to register a function to be called from Lua, however there are
two issues I'm running into:
1. I'd like to avoid passing a lua_state
Granted, this isn't going to be directly possible, but basically I'd
like to hide Lua from the rest of my application and instead have it go
through a proxy. So instead of:
int callback( struct lua_State *pLua );
I'd like to be able have something more like:
int callback( MyProxy *pProxy )
Where "callback" would query pProxy for the arguments supplied. This
way I don't have external code dependent on Lua directly.
Is there a clean way of doing this or should I just handle the double
indirection myself (i.e. the proxy is called back, and then it calls the
real function with appropriately parsed args)?
2. How to pass a "this" pointer?
Is there a standard way of passing a "this" pointer when calling C++
objects from Lua? Right now I'm using a global, which seems rather
