This worked fine on an older version of trunk that I had installed, but with the current trunk I can confirm the same problem. Can you please file a ticket? On Thu, Mar 10, 2011 at 9:01 PM, Mark Rada <mrada@marketcircle.com> wrote:
Hey all,
I am getting an error when I add a #to_s method to NSURL:
± irb irb(main):001:0> class NSURL irb(main):002:1> alias_method :to_s, :absoluteString irb(main):003:0> end => NSURL irb(main):004:0> NSURL.URLWithString( 'macruby.org' ) RuntimeError: can't modify frozen/immutable string

irb(main):006:0> test.to_s => "macruby.org" irb(main):007:0>
So the error seems to be macirb trying to do something to the string that is returned from #to_s.
I'm not sure if this is unique to MacRuby, as the CRuby documentation for Object#to_s doesn't say whether the returned object should be frozen, but should I be making #to_s return a mutable/unfrozen string?
