Describe the feature you want to add
The TextMate Plugin is bundled in IntelliJ (Community and Ultimate Version) and provides an easy way to add custom languages to IntelliJ, at least some features like basic syntax highlighting. The Plugin even includes some languages:

Adding new languages can be done in two ways:
- Importing the bundle yourself via TextMate Plugin Settings
- Community Plugins may use the TextMateBundleProvider Extension Point to include TextMate Bundles in their Plugin. And this is what I want.
