Using boost::python how can I create an a custom exception that is derived from Python's Exception? The functionality I would like to get by doing this is to provide additional methods for the catching code to retrieve information from the exception.
The approach I've taken in the past (sorry, don't have an example right now) is to raise a true Python exception (from PyErr_NewException), and attach your Boost.Python-wrapped C++ exception to it as an instance variable. Then put a __getattr__ in the true Python exception that forwards to the Boost.Python object it holds.
I can try to reconstruct more details if needed, but hopefully that's enough to get you started.
