I have not worked on syntax highlighting for vBulletin template syntax

In reality syntax highlighting beyond codemirror basics is barely needed (just a nicety), but was not very hard to add -- since there are so little keywords for vbulletin. If you are creating a large template you are still better off using a local editor, but when you need to maintain or do a quick edit, then codemirror really shines.

If I remember correctly @Nerbert's code creatively added codemirror for plugins. That should be a pretty nice asset for most users.

When I find some time, I will post some code for highlighting. If I remember correctly I just had to expand on one of the plugins for codemirror, but it has been some time since I looked over that code.

Yes you're right, infact the vbulletin mode js file isn't that hard, is just some lines of code. I just don't get why i can't use anymore addons when using it, i'll have to look on how modes are made, and do more tests to understand this problem

When I get a chance I will create a hightlighting plugin for @Nerbert's mod and he can add it to his modification.
