Jython Old Fork

Unsupported (friendly) fork of Jython 2.2 code, to modernize it so it runs under Windows 7 and includes a few 2.3/2.4 standard modules to aid in backporting scripts to run under 2.2.

This is a quick wiki for some old ports/forks of Jython.

Main things are:

  • Patched jython 2.2.1 for Java 1.4 - support more modern Windows operating systems and Python code; Windows 7, 8 and 10 support, adds libraries to make running code easier (e.g. logging, shlex.split(), optparse/optik, and Decimal) - see for how to build a new jar file
  • Patched jython 2.5.1 for Java 5 - remove PyDoc, pydoc as included with 2.5.1 does NOT work, causing failures with things like CherryPy if it finds a pydoc implementation (it works fine if its missing, it expects it to work if it is present). This was built by hand by removing pydoc.

Wiki features

This wiki uses the Markdown syntax. The MarkDownDemo tutorial shows how various elements are rendered. The Bitbucket documentation has more information about using a wiki.

The wiki itself is actually a mercurial repository, which means you can clone it, edit it locally/offline, add images or any other file type, and push it back to us. It will be live immediately.

Go ahead and try:

$ hg clone

Wiki pages are normal files, with the .md extension. You can edit them locally, as well as creating new ones.

Syntax highlighting

You can also highlight snippets of text (we use the excellent Pygments library).

Here's an example of some Python code:

def wiki_rocks(text):
    formatter = lambda t: "funky"+t
    return formatter(text)

You can check out the source of this page to see how that's done, and make sure to bookmark the vast library of Pygment lexers, we accept the 'short name' or the 'mimetype' of anything in there.

Have fun!
