Modify a C++ instance from the embed python interpreter

[Wezzy]

Hi, is there a tool that automatically expose an object to python? i
have an instance of a C++ (or ObjC) object and i want to pass it to the
embed interpreter that runs inside my program.
Python code have to call c++ method and register some callback.

I know that swig helps when python creates c++ instance but i've the
instance and i want to use it with python.

Thanks

That is the same case, wrt SWIG - the objects methods get accessed by
functions like

int Object_foo(Obje ct *s) {
return s->foo();
}
So passing a exiting object reference to such a function will work. You
might also consider using SIP, it appears to me to be much more OO.

Can you post few line of code ?

well i'll look to SIP but i prefer to use swig because it can interface
C++ with other language such as ruby
