RubyPython is a bridge between the Ruby and Python interpreters. It embeds a running Python interpreter in the Ruby application's process using FFI and provides a means for wrapping, converting, and calling Python objects and methods. RubyPython uses FFI to marshal the data between the Ruby and Python VMs and make Python calls. You can: * Inherit from Python classes. * Configure callbacks from Python. * Run Python generators (on Ruby 1.9.2 or later).
