Cocoa text editing component (for programmers)

Does anyone know if there is a code editing component for Cocoa, akin to Scintilla?

Or at least with following features: syntax coloring, indentation(, brace matching, whitespace showing, li开发者_如何学运维ne wrapping)?

You might have a look at smultron (now defunct). If I remember correctly, it gives a decent overview on how to implement syntax highlighting in an NSTextView.
