Building Cocoa Apps with MacRuby
by dan sinclair 20 Jun '10

20 Jun '10

Hello, I wrote up some thoughts on building cocoa applications with MacRuby last night and would love to hear any thoughts other people have. You can see the article at http://everburning.com/news/ramblings-on-programming-cocoa-with-ruby/ . I've been trying several different methods, HotCocoa, XCode templates, command line and haven't quite figured out a way that feels right and would love some insight from other developers. Thanks, dan

anyone wanna speak on MacRuby?
by Rich Morin 19 Jun '10

19 Jun '10

I recently gave a lightning talk on MacRuby at the East Bay Ruby Meetup Group (http://www.meetup.com/EBRuby/) Later, Jon Seidel (the organizer) and I agreed that it would be nice to have a full session on MacRuby. Problem is, I'm not qualified to give one. If anyone here is interested in giving such a talk and will be in the San Francisco Bay Area at some point, please get in touch. -r -- http://www.cfcl.com/rdm Rich Morin http://www.cfcl.com/rdm/resume rdm(a)cfcl.com http://www.cfcl.com/rdm/weblog +1 650-873-7841 Technical editing and writing, programming, system design

[MacRuby] #752: description -> to_s infinite loop

#752: description -> to_s infinite loop --------------------------------------+------------------------------------- Reporter: ryand-ruby@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: --------------------------------------+------------------------------------- I had a failing unit test that was causing an infinite stack trace. The code in question was: {{{ class SimpleNodeData attr_accessor :name, :path, :image, :expandable, :selectable, :container def initialize name = "Untitled", path = nil self.name = name self.path = path self.expandable = true self.selectable = true self.container = true end def compare other if SimpleNodeData === other return name.compare other.name end return NSOrderedAscending end alias :<=> :compare def description "%@ - '%@' expandable: %@, selectable: %@, container: %@" % [super, name, expandable, selectable, container] end alias :to_s :description end }}} That last alias is the real problem... comment it out and everything works fine. I believe the failing test line was: {{{ assert child.representedObject.path, child.representedObject.description }}} and the representedObject was a SimpleNodeData instance. -- Ticket URL: <http://www.macruby.org/trac/ticket/752> MacRuby <http://macruby.org/>

as workaround i can create the hash via NSMutableDictionary.dictionary or in my case : temp = YAML::load( NSString.alloc.initWithData( fileWrapper.regularFileContents, encoding:NSString.defaultCStringEncoding)) @data = NSMutableDictionary.dictionary @data.setDictionary(temp) is a bug or a behaviour that i do not understand?
