    Calling Python from Javascript?

    I know that there's some work out there to let Python make use of
    Javascript (Spidermonkey) via (I assume) some sort of bridging C/C++
    code. Anyone know of efforts to allow the reverse? I'd really like to
    make use of Python when doing Mozilla DOM programming, and I can never
    get a clear idea of when PyXPCOM might be available to those of us who
    don't know the ins and outs of compiling Mozilla, and its XPCOM
    structures. So if there was an easy way to simply and quickly pass even
    just strings back and forth between Python and Moz Javascript, that
    would make certain things a heck of a lot easier.

    Thanks,
    Ken

      Javascript can make requests to the server, and far as I know python
      can be used with either cgi or apache to respond to server requests.
      Therefore, javascript can easily pass strings to a server side python
      script, and it can easily handle data sent back that is formatted as a
      string, XML, or JSON. I'm not sure what PyXPCOM is or why it's
      relevant.

          I too wonder what happened to Mark Hammond's work on the
          DOM_AGNOSTIC_2 branch a year or so back. Might be nice to be able to
          write Firefox extensions in Python.

          Practically, I know that e.g. the firefox htmltidy extension (I forget
          the name) contains binaries built from C code, not just JS, so I guess
          you could write a Firefox extension that embeds CPython in a similar
          way.

              There are also some compilers for generating JS from Python (or
              Python-like) source. The pyjamas project has one (pyjamas is
              currently a port of GWT to Python), and I believe PyPy has a JS
              backend too. Both of those are serious work but experimental.
