#688: IB fails to read classfile in Ruby Cocoa project ----------------------------------+----------------------------------------- Reporter: tmowlem@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: MacRuby 0.5 Component: MacRuby | Keywords: IB XCode project ----------------------------------+----------------------------------------- Had a problem with Interface Builder parsing a XCode project using MacRuby. Raised a bug in Radar but Apple Engineering have responded that the issue is with macruby. Therefore raised as a ticket here. Full text of email thread reproduced below: Hi Timothy, This is a courtesy email regarding Bug ID# 7464509. Engineering has determined that this issue originates with MacRuby mailing-list. There is information here: http://www.macruby.org/contact-us.html The IB parser has been tested many times recently (especially the last few days), so we would be tempted to say that this is a problem with the project. Bug reports requiring your attention will appear under ‘My Originated Problems’. Please review this bug report and provide the requested information via the Apple Bug Reporter. Once your report has been updated, Engineering will be alerted of the new information. <http://bugreport.apple.com> Thank you for your assistance in helping us discover and isolate bugs within our products. Best Regards, Yvonne Villa Apple Developer Support Worldwide Developer Relations ************************************************************************** THE INFORMATION CONTAINED IN THIS MESSAGE IS UNDER NON-DISCLOSURE ************************************************************************** ------------------------------------------------------- Bug ID #: 7464509 Bug Title: IB fails to read classfile in Ruby Cocoa project ------------------------------------------------------- <GMT11-Dec-2009 18:01:20GMT> Summary: I have a Ruby Cocoa application project created using the template. At first IB was correctly seeing the .rb file as a class and discovering its outlets. But it has stopped doing so. Now if I select File->Read Class Files to force a re-read it parses the file then shows a red dimple in the IB project window at the bottom and displays an error message saying "Parsed 1 source file, but no classes were found or changed". I tried editing the source .rb and saving it. I also closed and reopened both IB and XCode but IB will not read the source any more. I did a Clean Build at some point before this behaviour started that could be related although I have no evidence to show that this was the cause. Steps to Reproduce: 1. Create a Ruby Cocoa project 2. Create a .rb class add some code and save it 3. Add some GUI objects eg buttons, popups, etc to the window in the main NIB 4. Add an Object to the NIB project window from the Library 5. Show the inspector, go the Identity tab and look for the ruby class in the Class popup Expected Results: The .rb class should show up and be selectable to set the class as the type of the object added to the IB project in step 4 Actual Results: IB completely refuses to see the .rb as a class. Also editing and saving the .rb file in XCode, reopening the apps or File->Reread class files should all cause a sync between XCode and IB. The .rb should then show up in the popup. It doesn't as described. Regression: none Notes: Please note that the project was working normally. Then it stopped working for no obvious reason. I can provide the project zipped up if required. But the code is proprietary (I am doing contract work for a client) so confidentiality would need to be respected in that case. <GMT03-Feb-2010 23:01:25GMT> Yes I can see the class in the classes tab of the IB Library window. It shows as a blue cube. The Lineage, Definitions, Outlets and Actions tabs also show what appears to be correct content yet the bug as described on File -> Read Class Files persists. <GMT12-Feb-2010 19:59:25GMT> 'GenRegData.zip' was successfully uploaded <GMT12-Feb-2010 19:59:25GMT> See attached. I have obfuscated the code to protect client confidentiality but the problem was still present. -- Ticket URL: <http://www.macruby.org/trac/ticket/688> MacRuby <http://macruby.org/>

Re: [MacRuby-devel] How do I subclass Obj-C classes in MacRuby?

For example, what I'm doing currently is this - module OpenDirectory class Node attr_reader :node def initialize config = { :node_name => "/Local/Default" } if config[:node_name].eql? "/Local/Default" @session = ODSession.defaultSession else @session = ODSession.sessionWithOptions config[:session_options], error:nil end @node = ODNode.nodeWithSession @session, name:config[:node_name], error:nil end end end so I can either local_node = OpenDirectory::Node.new or remote_node = OpenDirectory::Node.new proxy_config where proxy_config is a hash containing info for a DS remote connection to our directory master. I then access the ODNode as either local_node.node or remote_node.node where required. What I want to be able to do is just use local_node or remote_node as if they were ODNode objects (or subclasses of ODNode) to remove the ruby proxying wrapper around the core Obj-C objects, but still hide the ugliness of OpenDirectory behind some simpler Model style wrappers. (I hope that makes sense) cheers Russell

Aaron answer about convert the code of the Book to MacRuby
by Daniel Lopes 05 May '10

05 May '10

Hello folks, Some days ago I sent a message here with the idea to convert the Cocoa Programming For Mac OSX to MacRuby. Definitely MacRuby is a fantastical project but we need more examples and places where people, like me, could start your journey. I think if we have resources like this code for Aaron's book (and also Aimonetti's book) will be much easier for people to learn MacRuby or even learn pure Objc/Cocoa through MacRuby. I got in touch with Aaron asking if I can convert all his examples to the current version of MacRuby and share it with the community and his answer was: "Sounds great! You have my permission to make and distribute a set of solutions for "cocoa programming for mac OS x" in Ruby." My idea is place all the code in github and share it in MacRuby site. What do you think? Thanks

Perhaps I can get you started. I have converted the examples up to chapter 7 (something I did whilst looking for a new job) but stopped at that point because the KVO bindings was not working correctly. Just tried it with MacRuby 0.6 and all is working again. I can donate my code if you wish and you could carry on with the RaiseMan examples. Regards Christian

How do I subclass Obj-C classes in MacRuby?
by russell muetzelfeldt 05 May '10

05 May '10

Hi All, I've produced an ugly bunch of ruby that talks to OpenDirectory and am trying to clean it up a bit. Currently I'm using pure ruby classes that proxy Obj-C objects held in instance variables, but my goal is to have something structured like this - module OpenDirectory class Node < ODNode def find_user_by_name name ... end end end but I can't work out how to make a Ruby class that subclasses an Obj-C class and overrides the initialiser. With classes that descend from Obj-C classes the ruby "initialize" method doesn't seem to get called (because they're missing descent from the Ruby base Object class?), and all my attempts to override init result in 2010-05-05 15:55:34.237 macruby[2600:903] object 0x200249900 with 0 retain-count passed to CFMakeCollectable. and a segfault. Attached below is a reduced case, if anyone can point out how to get a valid MyNode object it'd be much appreciated. If node is a real ODNode (as in the commented lines) all works correctly. I'm not calling super, since the object has (I believe) already been alloc'd and I'm explicitly calling the designated initializer later in my own init. If I *do* call super in my own init, I just get an additional "object 0x... with 0 retain-count passed to CFMakeCollectable" error. If I use ODNode.nodeWithSession:name:error: in my own init the example below works, but I end up with an ODNode rather than a MyNode so it's missing any methods I'm adding to my own class. (I'm also unsure whether I need to be retaining the session in an instance variable myself or if it's also being retained in the ODNode, but that's another question.) Any pointers very much appreciated... Russell example: framework 'OpenDirectory' # no BridgeSupport for CFOpenDirectory.framework... :( Users = "dsRecTypeStandard:Users" RecordName = "dsAttrTypeStandard:RecordName" MatchEqualTo = 0x2001 RealName = "dsAttrTypeStandard:RealName" # some account name to search for me = "russm" class MyNode < ODNode def init @session = ODSession.defaultSession STDERR.puts "===== pre CFMakeCollectable error" self.initWithSession @session, name:"/Local/Default", error:nil STDERR.puts "===== post CFMakeCollectable error" self end end node = MyNode.new #session = ODSession.defaultSession #node = ODNode.nodeWithSession session, name:"/Local/Default", error:nil query = ODQuery.queryWithNode node, forRecordTypes: Users, attribute: RecordName, matchType: MatchEqualTo, queryValues: me, returnAttributes: RealName, maximumResults:0, error:nil STDERR.puts "===== pre segfault" results = query.resultsAllowingPartial false, error:nil STDERR.puts "===== post segfault" result_attributes = results[0].recordDetailsForAttributes nil, error:nil puts result_attributes.inspect

MacRuby and Shoulda
by Mike Taylor 05 May '10

05 May '10

Has anyone had any luck using Thoughtbot's Shoulda gem with MacRuby for testing? I'm getting errors like this: 1) Error: test: My factorial method should return 1 when passed 0.(TC_Test): NoMethodError: undefined method `test: My factorial method should return 1 when passed 0.' for #<TC_Test:0x200240f60> I'm fairly new to both Ruby and MacRuby. I'm not sure if the problem is due to MiniTest replacing Test::Unit in Ruby 1.9. Or, if it is a MacRuby issue. Here's my simple test file that works in ruby 1.8: require 'rubygems' gem 'thoughtbot-shoulda' require 'shoulda' require 'test/unit' def fact(x) return 1 if x == 0 return (1..x).inject(:*) end class TC_Test < Test::Unit::TestCase context "My factorial method" do should "return 1 when passed 0" do assert_equal 1, fact(0) end should "return 1 when passed 1" do assert_equal 1, fact(1) end should "return 6 when passed 3" do assert_equal 6, fact(3) end end end I'll keep on digging, but if anyone has any insight, I'd appreciate it! /\/\ike

ActiveSupport in MacRuby 0.6?
by Leigh Caplan 05 May '10

05 May '10

I remember reading that ActiveSupport was going to be supported in MacRuby 0.6, however version 2.3.5 of the gem still fails to load with the following message: irb(main):003:0> require 'activesupport' NoMethodError: undefined method `alias_method_chain' for Range:Class Same thing happened in 0.5... On an unrelated note, I now seem to be unable to run macgem, macirb, etc without sudoing – if I try to run as my ordinary user, I seem to time out with an "abort trap." Tried explicitly granting +r permissions on the MacRuby.framework itself, but no dice. Anyway, help is much appreciated. And thanks to everyone working on this project! Leigh

Amazing. I'm mostly amazed by this specific breakthrough: "MacRuby 0.6 provides support for C extensions written for the original implementation of ruby. We were able to successfully use the Nokogiri, SQLite3 and PostgreSQL extensions from MacRuby." How did you manage to install the PostgreSQL extension with macgem? Any special setup?
