Would it be possible to integrate Python (and/or Perl) and Ruby? I’ve looked at http://www.goto.info.waseda.ac.jp/~fukusima/ruby/python/doc/ and http://code.google.com/p/ruby-perl/ , but they both seem rather outdated.
Has someone generated a Ruby interface for Python’s C API?
Edit: Python can be integrated with many other languages according to http://wiki.python.org/moin/IntegratingPythonWithOtherLanguages . However, that list doesn’t include Ruby.
Integrating dynamic languages is one of the goals of the Parrot project. It’s a virtual machine that dynamic language compilers target. Once compiled to the same virtual machine, you should be able to used the “object” form in any of the languages no matter the object’s source.
The issue at the moment, however, is stabilizing the virtual machine and finishing off the mostly done compilers. However, that’s been the state for a long time. 🙂
