Re: binding a c++ unary_function to lua

[Graham Wakefield <lists@...>]

Maybe I'm misunderstanding something, but as stated, the function is not static, and can't be registered with Lua anyway.  As with other non-static methods, you need to create (or auto-generate in some way) a wrapper function that is static, which can in some manner access the instance, such as through a Lua upvalueindex or userdata argument on the stack, in order to call the instance method with an object.

While experimenting with stl binders yesterday, I had the following

problem.  Let's say we have a

derived from std::unary_function c++ struct with the method:

int operator()(lua_State *L) const { ... }.

Is there any easy way to make it available to lua as a normal function?

thanks in advance,

Be seeing you
