I have been playing a little with the jaap variation.

3 remarks at the moment:

1. (strictly technical - easy(?) fix)

   In the js file on line 43 the regexp for "quoted strings" reads:

   /('|"|`).*?\1/

   I want to propose the following regexp for this purpose, which handled multiline quotes and embedded escaping correct in my (limited) tests (UA: FF2, IE7)

   /('|"|`)(?:\\\\|[\r\n]|\\\1|.)*?\1/

2. (technical (?!) - no fix for now)

   while testing the above with IE7 I noticed that the "autowrap" problem can not be worked around with the display settings in this browser. (A lot of linebreaks are just ignored.) Somebody who does feel more pity than me for IE7-using perlmonks might have a look into this. I didn't test IE6 for lack of availability at the moment

3. (personal opinion on usefulness)

   While I'm not totally convinced if I stay with highlighting on code-blocks, I found the feature quite useful with inline-code!

   To activate inlinecode highlighting add

    || pre.className == "inlinecode"

   to the if condition in line 156 at the end of the js file.
