#init & #initialize
by Eloy Duran 19 May '08

19 May '08

In the RubyCocoa layer I would like to have #initialize called from #init, because in RC it was allowed to use #initialize and thus many classes do this. Anyways, here's some test code, please note the comments and the output which are basically my questions :) Cheers, Eloy #!/usr/local/bin/macruby class Foo def init if super puts 'Foo init' self end end def initialize puts 'Object' end end class Bar < NSObject def init if super puts 'Bar init' self end end def initialize puts 'NSObject' end end # Calls only initialize which is a good thing because it's a "Object" subclass. Foo.new # => Object # Calling new on a NSObject subclass calls initialize, but NOT init!!!?? Bar.new # => NSObject # Calls only init and NO initialize Bar.alloc.init # => Bar init # Add behaviour to have initialize called from init class NSObject # Note: Should I somehow alias the original NSObject#init? # Trying to alias it results in a NoMethodError. def init initialize self end end # Calls init and then initialize. Bar.alloc.init # => NObject # => Bar init

framework cannot be loaded
by Eric Johnson 15 May '08

15 May '08

Hi - I'm excited about the macruby project. I just started playing with it. It's a great tool to get to know the frameworks on OS X. I created a quick script that imports all frameworks in /System/Library/Frameworks - however, it fails on some of the frameworks. I'm not sure what exactly is going on. Here is some sample code: frameworks = `ls /System/Library/Frameworks/` frameworks.chomp! frameworks = frameworks.split frameworks.each do |f| f.gsub!('.framework', '') end frameworks.each do |f| framework f end It dies with this error: 2008-05-15 12:32:25.564 macruby[2894:10b] Error loading /System/Library/Frameworks/ICADevices.framework/ICADevices: dlopen(/System/Library/Frameworks/ICADevices.framework/ICADevices, 265): no suitable image found.

That's probably because I came to Ruby from > ObjC, not ObjC from Ruby... I kept wishing that: > > super.foo() would work. Is that possible? Hi Pierce, That syntax wouldn't work because calling "super" will call the method you're in from the superclass. AND it may/will return an object. In your example you are calling #foo on the result object of the super call. But that would be the functionality I suggest yes. About the weird syntax in RubyCocoa, I agree. But this wouldn't be a compatibility layer without supporting it's intricacies now would it :) Eloy PS: Is it me or is the return-path for the emails coming from the ML incorrect? I guess it should point to macruby- devel(a)lists.macosforge.org instead of Pierce...

Trying to get rubygems to run.
by Eloy Duran 06 May '08

Hi, (Here are some of my first minutes of playtime with MacRuby.) The first time I configured and made/installed MacRuby, I noticed that zlib wasn't installed while trying to use RubyGems (/ usr/local/bin/macgem). I'm not exactly sure what the cause was and why the third time around it did make and install it. I had tried once to make zlib itself and it outputed that there's nothing to be done for all. I then deleted the Makefile and ran: $ macruby extconf.rb and after that running make did work. But then I did a clean and a distclean and manually removed the Makefile again. This time it did work... Am I the only one to have encoutered this? Also after that had been resolved it seemed that the gem directories were missing: /Library/Frameworks/MacRuby.framework/Versions/0.2/usr/lib/ruby/Gems/ 1.9.0/cache /Library/Frameworks/MacRuby.framework/Versions/0.2/usr/lib/ruby/Gems/ 1.9.0/doc /Library/Frameworks/MacRuby.framework/Versions/0.2/usr/lib/ruby/Gems/ 1.9.0/gems /Library/Frameworks/MacRuby.framework/Versions/0.2/usr/lib/ruby/Gems/ 1.9.0/specifications After creating those I still have a non functional rubygems. Trying to install a gem just hangs after: 1:% sudo macgem install mocha --debug Exception `NameError' at /Library/Frameworks/MacRuby.framework/ Versions/0.2/usr/lib/ruby/1.9.0/rubygems/command_manager.rb:132 - uninitialized constant Gem::Commands::InstallCommand Trying to update rubygems yields: 137:% sudo macgem update --system --debug Exception `NameError' at /Library/Frameworks/MacRuby.framework/ Versions/0.2/usr/lib/ruby/1.9.0/rubygems/command_manager.rb:132 - uninitialized constant Gem::Commands::UpdateCommand Updating RubyGems...
