How hard would it be to implement some kind of code highlighting for anything inside the <code> tag? Does anyone know of any perl-to-html code highlighting module type thing?

    Such a scheme would have to be optional of course, as I don't think highlighting an obfuscation would be such a good idea (on top of being probably quite difficult!)

    It sounds like an interesting exercise, but one that wouldn't be particularly nasty: there are already syntax-coloring filters for perl out there (consider that both vim and cooledit have them, and cooledit has the peculiar misfortune of being written in python). It shouldn't require much more than turning the ANSI escape sequences in the syntax-highlighting routines in vim into the corresponding <SPAN> tags in HTML. Getting <SPAN> recognized inside of <CODE> is another matter altogether -- <CODE> is designed to indicate to the browser that as much as possible within the block is to be treated literally.

      Using <code> tags in your post doesn't actually put a <code> tag in the html output when you view it (check the source). One of the reasons I suggested it is because there's already some kind of magick going on with <code> tags, so I figured that it might be as easy as putting in a sub for the code highlighting along with $code = highlight_code($code) if $user_prefs{'wants_highlighting'} in the bit that deals with the code. (Dammit! I've got <code> on the brain now after using it 16 times in this post. :-)
      While we're discussing syntax coloring in editors, Glimmer has syntax coloring since way before it was called Glimmer. But then again, what use is that in the Monastery? Looking into PerlTidy is probably a good thing.
