Thanks, that seems like a good idea.
I've been looking at the markdown and linebreak parser plugins to see
how to do it, but I can't get it to work.
Just to get the first step working (modifying the page content), I use
this code (comments stripped for clarity):


__author__ = 'Dieter Plaetinck <dieter-7FYLOmueu/[email protected]>'
__version__ = "0.1"
PREFORMATTER_ID = 'pygments'

import re
def cb_preformat(args):
    if args['parser'] == PREFORMATTER_ID:
        return parse(''.join(args['story']))

def parse(text):
    text = re.sub('\n','<h1>somethinghappens</h1>',text)
    return text


and my config:
$ grep pygment /srv/http/dieterblog/config.py
py["load_plugins"] = ["comments", "tags", 'pygments']
py['parser'] = 'pygments'
the code is in this file: /srv/http/dieterblog/plugins/pygments.py

Normally I should see "<h1>somethinghappens</h1>" all over the place,
right?  But my pages are the way they were before, as if it's still
using the plain parser.  When I use the debug renderer it confirms that
Request.get_configuration() dict contains parser -> pygments

No errors in my lighttpd error log either.
