Text to HTML converter for Google App Engine

I need a script that converts plain text into HTML (eg like the one in reddit comments system). There are plenty of those out there, yeah, but I need one that could work with Google App Engine (and Python).

It could be great if the script could work both ways: for encoding the text and decoding it back from HTM开发者_开发问答L (for editing saved texts).

Thanks in advance!

There's multiple 'humane' markup languages, and no particular reason for any of them to not work in App Engine. My blog engine, bloggart, for example, supports several via their standard Python libraries.

Instead of attempting to convert HTML back to markup, you should be storing the original, un-mangled markup the user input, and allowing them to edit that, instead.
