LiveReload can compile LESS, SASS, Compass, CoffeeScript, Jade and others into corresponding css/js/html files.
The following compilers are currently supported:
- Compiled into CSS: SASS/Compass, LESS, Stylus.
- Compiled into HTML: Jade, HAML, Slim.
Internally we're using a plugin-like model, and you can easily add support for additional languages if you're adventurous enough (look at *.lrplugin/Info.plist inside the app bundle). There is no official plugin API yet, however (we need to figure out both technical and App Store policy details).
