syntax highlighting is broken using coderay

[Claudio Bley]

The coderay syntax highlighting library redmine is using changed the HTML output of short-form CSS class names (like pp) to longer names (like preprocessor) a year ago.

Redmine changed their names also, but the package of ruby-coderay which is currently used by redmine still uses the old names.

This breaks syntax highlighting in redmine, ubuntu 12.04 LTS.

Anyone progress on this fix?

[Claudio Bley (cbley)]

Here's a patch which adds back the old CSS rules, leaving the (new) long CSS names intact.

I extracted those rules from some old version out of the repository. HTH.

the above diff patch did not work for me, still the git repo code review has no syntax highlighting...

I can confirm the patch in #3 fixes the highlighting. The patch doesn't directly apply (you need to tell it which file to patch since scm.css.orig doesn't exist on your system) but it does fix the problem. It's not a definitive fix from upstream, but it does get you to the intended display.
