As a related aside - when I was playing with some javascript for a work
related project which involved creating a web page for viewing large amounts
of data by using folding I thought to myself "Hmm I could use this to create a
foldable viewer for Python code".  I had hoped to just modify an existing
py2html type thing and just insert my own code.  This turned out to be rather
hard, even trying some of the source code parsers turned out to involve orders
of magnitude more effort to do the job properly than I expected so I abandoned
it.  At some point I may try going back to a simple regex version even though
it won't work on all sources.

Anyway, grumbling aside, a test version of a formatted page is viewable here:
<A"href=http://homepages.ed.ac.uk/eddie/d.html">http://homepages.ed.ac.uk/eddie/d.html</A>
 The page was a part of the pydoc code which was chosen only because it was
big enough to generate a reasonable test.

Some notes BEFORE you click!

o This was done weeks ago and I can't remember exactly what state the system
  was in when I created this particular file but it should show you what was
  intended.
o To the best of my knowledge and ability it uses only standards compliant
  javascript and CSS which means (the last time I checked) that currently only
  Mozilla displays it properly (well I didn't check Opera etc. but I do know
  that IE couldn't do it).
o It's not fast.
o As a testing hack it detects key-presses to pop-up an inline menu (this one
  bit that IE really screws up on).  The options are:
  find - highlight lines containing search string - unfolds any level that is
         needed in order to make each line visible
  expand/collapse all - should be obvious
  expand/collapse selected - the last node you clicked on to expand or
         collapse it will select that item (should be highlighted in red)
o It's not finished!
o The points where folding is done are currently only def and class I think,
  the final version was to support anything that could be indented.

Anyone who wants to is welcome to play with it.  I have some simple Python
classes for creating the relevant javascript, that may be more complete - I'll
have to dig it out and check.  Perhaps I'll have another go at finishing the
whole thing during the yuletide hols.
