If you're a bundle author, please edit the below & upload the bundles here, rather than linking to messy forums. Also, please fill out any missing info, including bundle version (use date if you're not tracking versions), which version of the Unity API the bundle supports, iPhone API support, etc.
If you want to make a change to an existing bundle, i.e. include your own formatting, folding etc. please first post in the discussion page before updating the bundle and allow 1 day for feedback. This gives people who follow this page a chance to consider the changes for inclusion (this is intended Wiki usage).
Lastly, feel free to edit the formatting, appearance, etc. of the entries; it's OUR wiki after-all! :)
Sublime Text (OSX, Windows, Linux)
Sublime Text is a popular cross-platform text and source code editor. It is extendable and its community has contributed numerous packages(plugins/extensions/addons) for Sublime Text.
Feel free to edit the mode; however, it would be appreciated if you could donate me from my website JnaniDev.com. I will soon be coming out with modes for Boo and C#. Enjoy!
