Thanks Matt: Good tutorial on super. Maybe someone could add a keyword section to ruby-doc. This leads me to a couple more questions on super and MacRuby inheritance: 1) Does MacRuby distinguish between Objective C subclasses and other Ruby classes or are all classes treated the same? 2) Can my inheritance path be arbitrarily long before I inherit from NSObject or an NS subclass? 3) If I have an empty init, e.g., def init; super; self; end Can I always delete the empty init and get the same result through inheritance?

You can certainly call super in your subclass before making any modifications or calling super based on a condition.
I hope it helps,

Thanks Matt:
I didn't see super in the ruby-doc.org/ruby-1.9/index.html unless super is short for superclass.
Can I reach a superclass method without having the message go first to my subclass override of the method?

No it's not unique to MacRuby (Ruby and Obj-C support that feature) and yes you can pass other arguments :)

Questions on the super method:
Is the super method unique to MacRuby?
super forwards the current message to the superclass with the same method name and arguments. Is there a way to send a message to the superclass method with different arguments either from within the subclass method of the same name or from outside the subclass method of the same name to bypass the subclass method?
Thanks, Bob Rice
