I would like to do syntax coloring and code completion on any given code. Ideas inspired by Apple videos http://devimages.apple.com/llvm/videos/Libclang.mov
Can someone tell me about a sample project that uses libclang to parse objective-c code?
Take a look at the Étoilé project: http://etoileos.com/news/archive/2010/10/15/1401/
There you will find SourceCodeKit, which combines clang for syntax highlighting. (Source: http://svn.gna.org/viewcvs/etoile/trunk/Etoile/Languages/SourceCodeKit/ )
