Modify a C++ instance from the embed python interpreter
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.
