I’ve been an avid TextMate user and fan for the past couple of years, and I’ve also used Trac at several jobs now. I never like editing anything substantial, like Trac wiki, pages in a web browser text widget, so I use TextMate’s “Edit in TextMate” plugin exhaustively. Over the past couple of years, those things led to my creating and evolving a Trac bundle for TextMate.
It’s still pretty simple, which I think is a good thing. I haven’t had a need for it to do anything very complex. So far, it has a fairly decent language grammar for Trac wiki syntax that defines some reasonable scopes, following the conventions of markup scopes defined in other bundles. It has several useful wiki formatting snippets and commands, from simple stuff like bold and italic, to a rudimentary snippet for creating tables. It also parses wiki headings (e.g. == My Heading ==
), and wiki links as TextMate symbols, so you can jump around in wiki pages easily using the symbol pop-up.
If you’re interested, head on over to the Google Code project page and try it out. Please let me know if you find it useful. Suggestions are always welcome, too.
