I decided to push to github a quick experiment I worked on the other night. http://github.com/mattetti/macruby-doc-app/tree/master It's simple, dirty and not fully working, but it queries the Cocoa API and displays the first result in a webkit view. My hope is to convert it to the new MVC framework and to maybe use a nib to define the UI. It should also let you pick which result to display instead of just picking the first one. Eventually, the app should parse the mappings to know what cocoa API to look someone would search for one of the HotCocoa helpers. Also, if we can get nokogiri FFI to work on 0.5 pretty soon, we could parse the result and display it differently. Anyways, I don't have much time so feel free to hack on this project if you feel like it. - Matt
