Comment(by martijn@…):

 Replying to [comment:4 lsansonetti@…]:
 > Looks like the class_addProtocol() runtime function could be used. I
 wonder if we can call it automatically, once all methods of a known
 protocol are defined.

 To me, it feels there might be too much 'magic' in automatically adding
 protocols a class conforms to. Plus, there are plenty of protocols with no
 required but only optional methods. Would all MacRuby classes then
 automatically conform to these protocols? I don't mind manually indicating
 what protocols a class supports, as this helps make explicit what its
 responsibilities are.

 So what about just adding a class macro that calls class_addProtocol()
 during class definition?

 {{{
 #!ruby
 class SourceListController
   add_protocol :NSOutlineViewDelegate

   def outlineView(outlineView, child:index, ofItem:item) ... end
   ...
 end
 }}}
