Hi everyone,

I'm a little bit stuck in my efford to improve syntax highlighting in my Redmine instance and hope, you can help. I have two goals I'd like to achieve:

1. Have more Languages supported for syntax highlighting
2. Have syntax highlighting in diff view

Have more Languages supported for syntax highlighting¶

I'm using Redmine 2.6.0, which seems to use CodeRay by default. CodeRay only supports the following syntaxes:

C, C++
Clojure (new)
CSS
Delphi
diff
ERB
Go
Groovy
HAML (new)
HTML
Java
JavaScript
JSON
Lua
PHP
Python
Ruby
Sass
SQL
Taskpaper
XML
YAML

I'm missing Bash/Shell and Django support a lot! Since I do very much with this, I'd like to have these highlighted.

There seems to be an alternative, which aims to implement Textmate's syntax highlighting files, named redmine_ultraviolet , which supports the following:

This includes all I need and more, but I don't get it running with Redmine 2.6.0 on Ubuntu 14.04 :(
Maybe someone has a hint or a link to a little tutorial to get it running?

Have syntax highlighting in diff view¶

When in Repository tab and opening any file which's syntax is supported, it is highlighted:

When watching a diff, there is no highlighting:

I'd like to have it look like diff view in Phabricator; that is: Marking changed lines and have syntax highlighted:

Is this possible somehow?
