ext/rubypython_bridge/rp_object.c

Overview

A wrapper class for Python Modules.

Methods calls are delegated to the equivalent Python methods/functions. Attribute references return either the equivalent attribute converted to a native Ruby type, or wrapped reference to a Python object. RubyPyModule instances should be created through the use of RubyPython.import.
