in reply to Code highlighting?
Personally i am in favour of something like this. BUT its not so straightforward, and there are legitimate issues such as load, and theme sensitive color schemes that need to be addressed for such an endeavour. Presumably we could use the HTML output form of Perltidy, but Perltidy is a known resource hog.
You should have a look through the PMD archives as this subject comes up fairly regularly and the comments made before will still be relevent now.
First they ignore you, then they laugh at you, then they fight you, then you win.
