[MacRuby-devel] MacRuby Working Properly?

[Andy Park]

The Ruby String class is a subclass of NSString:

MacRuby-0.12 irb(main):001:0> "foo".class.ancestors
=> [String,
 NSMutableString,
 NSString,
 Comparable,
 NSObject,
 PP::ObjectMixin,
 Kernel,
 RbConfig]


In order to get the list of all methods that an object responds to, including those defined in Cocoa classes, use #method(true,true):

MacRuby-0.12 irb(main):003:0> "".methods(true,true).count
=> 763
