in reply to syntax highlighting of code in perlmonks forums

Parsing Perl well enough to do a good job of syntax highlighting is hard. The ony program I've seen that seems to get it right all the time is perltidy. It's 20,000 lines of Perl, most of which aren't concerned with syntax highlighting. But that gives a sense of the scale of the problem.

So, let's say you had a special tag, <perl_code> has been suggested here, that would run the tag contents through perltidy --html. The highlighting is implemented with a CSS stylesheet, which could be incorporated into the standard site CSS. To turn off the highlighting, or to implement your own style, just add a custom stylesheet.

Of course, it would still be a significant load on the server(s).

[Corion]: Also, London is always a nice visit, as I got to meet a friend there, and spent some time offline, working on "minor" features of the shadertoy thing ;)
[marto]: maybe next year when the kids are a little older I'll have time to attend perl events in Europe
[Corion]: marto: Yeah - there isn't a Perl Day-Care at Perl events - we thought about it for YAPC::Europe 2012 but it's a gigantic effort to organize that
[marto]: Corion yeah, it'd be too costly for me to bring them both :P
