Blogs posts and another links in macruby website
by Daniel Lopes 26 Apr '10

26 Apr '10

I just forked macruby website and want to add some new links in documentation page. The problem is the website doesn't have a space for that. I'm thinking in create a new session inside http://localhost:4331/documentation.html with the title "Misc" or "Another Resources". My idea is share this links for now: Objective-C for Ruby developers, un not-so-petit interlude (1/2)<http://blog.phusion.nl/2010/03/24/objective-c-for-ruby-developers-un-not-so…> Creating our very first Mac application with Ruby, how exciting!<http://blog.phusion.nl/2010/03/12/creating-our-very-first-mac-application-w…> A gentle introduction to MacRuby<http://blog.phusion.nl/2010/03/12/a-gentle-introduction-to-macruby/> http://public.me.com/johnmshea And keep adding new posts. What do you think?

NSNotificationCenter observers, selectors and notifications
by Allison Newman 24 Apr '10

24 Apr '10

Hi peoples, I'm not sure if I'm doing something wrong here, or if it's a bug. I'm trying to get a notification when a quicktime track finishes playing. The documentation for NSNotificationCenter says: notificationSelector Selector that specifies the message the receiver sends notificationObserver to notify it of the notification posting. The method the selector specifies must have one and only one argument (an instance of NSNotification). yet, if I use a selector that takes one argument, there is an error when the NSNotificationCenter tries to notify me: 2010-04-24 12:06:49.587 macruby[5042:903] -[Player track_finished_with_notifier]: unrecognized selector sent to instance 0x2002c3d40 On the other hand, if I give a selector that doesn't take any arguments at all, it is in fact called by the NSNotificationCenter at the right moment. I've included a quickly hacked up script that shows the problem at the end of this message. I'm using macruby 0.5 on Snow Leopard, so maybe the bug (if it is indeed a bug, and not an error on my part) is already fixed... To run the script you'll have to replace Evanescence and Going Under with a group/track that you have in your iTunes library... Alli #!/usr/local/bin/macruby require 'rubygems' require 'hotcocoa' framework 'Cocoa' framework 'QtKit' include HotCocoa class Player def init NSNotificationCenter.defaultCenter.addObserver(self, selector: :track_finished, name:QTMovieDidEndNotification, object:nil) NSNotificationCenter.defaultCenter.addObserver(self, selector: :track_finished_with_notifier, name:QTMovieDidEndNotification, object:nil) movie = getQtMovieFromArtist('Evanescence', track:'Going Under') movie.volume = 30 movie.play puts "playing..." sleep(10) self end def getQtMovieFromArtist( artist, track:track_name) iTunesXMLPath = "#{NSHomeDirectory()}/Music/iTunes/iTunes Music Library.xml" iTunesData = NSDictionary.alloc.initWithContentsOfFile(iTunesXMLPath) tracks = iTunesData.objectForKey('Tracks') artist_db = tracks.find_all { |track| track[1]['Artist'] == artist} track_db = artist_db.find{|track| track[1]['Name'] == track_name} url = NSURL.URLWithString(track_db[1]['Location']) errorptr = Pointer.new_with_type('@') movie = QTMovie.movieWithURL(url, error:errorptr) if (!movie) error = errorptr[0] puts "Error loading song: #{track_db[1]['Name']} #{error.code} #{error.localizedDescription}" end movie end def track_finished NSLog( "track finished!") end def track_finished_with_notifier(notifier) NSLog("track finished with notifier #{notifier}") end end class Application def start application :name => "Player" do |app| app.delegate = self Player.new end end def on_new(sender) Player.new end def on_close(sender) w = NSApp.mainWindow if w w.performClose self else NSBeep() end end def on_clear(sender) w = NSApp.mainWindow if w and w.respond_to?(:terminal) w.terminal.clear else NSBeep() end end end Application.new.start

MacRuby doesn't find kCGDesktopIconWindowLevel
by Michel Steuwer 24 Apr '10

24 Apr '10

Hello everybody, i'm new to MacRuby and currently trying my first Project. I try to draw a NSPanel at the desktop window level. Therefore, i would use the [window setLevel:kCGDesktopIconWindowLevel] method in Objective-C. In MacRuby the call window.setLevel(kCGDesktopIconWindowLevel) doesn't work and produces the following log message: undefined local variable or method `kCGDesktopIconWindowLevel' for #<PanelController:0x2002f1ac0> Currently i have solved the Problem by using this work-around: window.setLevel(CGWindowLevelForKey(2)) Why can't i use the call with the pre defined constant as i would in Objective-C ? Thanks, Michel -- Michel Steuwer | michel.steuwer(a)onlinehome.de
