NSLocaliszed* functions missing
by Dave Baldwin 20 May '10

20 May '10

With macruby 0.6 when I try and use NSLocalizedStringFromTable I get the following: ~> macirb irb(main):001:0> framework 'cocoa' => true irb(main):002:0> NSLocalizedStringFromTable('', '', '') NoMethodError: undefined method `NSLocalizedStringFromTable' for main:TopLevel from /Users/dave/(irb):2:in `<main>' I believe NSLocalizedStringFromTable is part of the Foundation framework. Also all the other NSLocalized* functions seem to be missing. Dave.

CSV still buggy
by Louis-Philippe 19 May '10

19 May '10

Hi, I saw: Ticket #125 (closed defect: fixed) about CSV. I do a pretty simple test: ####### require 'csv' CSV.open('testCSV.csv', 'r') do |row| p row end ####### this test works in ruby 1.8.7, but in macruby 0.6 I get an empty reader... my arch is: MacRuby version 0.6 (ruby 1.9.0) [universal-darwin10.0, x86_64] thanks!

MacRuby class inside obj-c
by Louis-Philippe 19 May '10

19 May '10

Hi, I don't know if this is the good list to ask this question as it is my first... So, I saw how I can have a MacRuby cocoa app, importing objective-c classes. I can't find info on how to do the opposite... having an Objective-C cocoa app, importing and using MacRuby Classes... All I managed to do is to "evaluateFileAtPath:" and "evaluateString:" Thanks!

Threading Problems
by Jan Kassens 18 May '10

18 May '10

Hi, I’m writing a small widget application rendering a couple of NSView subclasses which update periodically. The widgets are subclasses of [1] and added as subviews to my main view, but the more I add the more likely are some random errors thrown on initialization. The errors include a variety of failed assertions and seg faults (see [2] for examples) and don’t yield any helpful clues. I’m guessing that I’m dealing with something not thread-safe here. Am I doing something wrong here? I’m doing all the drawing inside the drawRect(rect) method (or synchronously called methods) which I don’t call manually. “update” pulls data from various resources, but doesn’t draw. [1] WidgetView class: http://pastie.textmate.org/private/hwfozrwudk2lcwzker20q [2] Different Errors: http://pastie.textmate.org/private/vbp7iuw11ig26zxegzg Jan

Using a context with addObserver
by Dave Baldwin 18 May '10

18 May '10

I am trying to translate code that looks like this: static NSString *SKTWindowControllerCanvasSizeObservationContext = @"com.apple.SKTWindowController.canvasSize"; and later [[self document] addObserver:self forKeyPath:SKTDocumentCanvasSizeKey options:NSKeyValueObservingOptionNew context:SKTWindowControllerCanvasSizeObservationContext]; to Ruby: SKTWindowControllerCanvasSizeObservationContext = "com.apple.SKTWindowController.canvasSize" document.addObserver(self, forKeyPath: SKTDocumentCanvasSizeKey, options: NSKeyValueObservingOptionNew, context:SKTWindowControllerCanvasSizeObservationContext) but when it runs I get this error: expected instance of Pointer, got `"com.apple.SKTWindowController.canvasSize"' (String) (TypeError) How do I get the a pointer to the context string? All the examples I have found for the Pointer class seem to expect an objective C routing to fill it in. Thanks, Dave.

Hi, in a little macruby-cocoa app when i try to save a simple hash (attribute of a model class) inside the fileWrapperOfType method via Marshal.load( Marshal.dump((a)model.data)) #deep copy , i get an error: `fileWrapperOfType:error:': can't dump anonymous class #<Class:0x20065e4e0> (TypeError) i discover that the hash attribute of the class is referenced as anonymous class child of an Hash this happens with MacRuby 0.6 (also last nightly build), not with 0.5 Thanks for any help and workaround Ciao

[MacRuby] #721: Compiled ruby files return incorrect values for __FILE__

#721: Compiled ruby files return incorrect values for __FILE__ ---------------------------------+------------------------------------------ Reporter: mred@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: ---------------------------------+------------------------------------------ Beginning with files "test_file.rb" {{{ puts "__FILE__ = #{__FILE__}" }}} and "main.rb" {{{ require 'test_file.rb' require 'test file.rbo' }}} arranged like this {{{ / tmp ruby test_file.rb ruby2 main.rb }}} I then issued the following commands starting in the /tmp directory {{{ macruby -C ruby/test_file.rb -o ruby2/test_file.rbo mv ruby/test_file.rb ruby2 cd ruby2 macruby main.rb }}} and got the following results {{{ __FILE__ = /tmp/ruby2/test_file.rb __FILE__ = ruby/test_file.rb }}} The incorrect __FILE__ values make it very difficult design a hierarchy of files and then load them using 'require' and relative paths for example. -- Ticket URL: <http://www.macruby.org/trac/ticket/721> MacRuby <http://macruby.org/>

MacRuby book, new chapter 1 - better example
by Matt Aimonetti 16 May '10

16 May '10

Based on all the great comments I received about the draft of my MacRuby book http://macruby.labs.oreilly.com I decided to rewrite the introduction chapter and move away from the AddressBook example and instead built a hello world GUI app. [image: ch01_hello_world.png] http://macruby.labs.oreilly.com/figs/ch01_hello_world.png I just republished the first chapter online http://macruby.labs.oreilly.com/ch01.html and I would really appreciate your help reviewing it and letting me know what you think. I received quite a few questions about the book content and/or MacRuby questions related to the book. While I don't mind responding by emails, I figured it would be best if we would do that in public way so I created a new google group for people reviewing the book but also for people learning MacRuby through the book: http://groups.google.com/group/*macruby-book-review*<http://groups.google.com/group/macruby-book-review> Thanks, - Matt

Support for the DataObjects drivers with the C api
by Dirkjan Bussink 15 May '10

15 May '10

Hello all, I recently read that Macruby is also adding support for the C api that MRI provides. Since I maintain the DataObjects (do_*) drivers, I'd also like to support Macruby next to the existing support for MRI 1.8 / 1.9 (with full encoding support), JRuby and Rubinius. I'd like some help with the following things: - What is the easiest way to set up a development environment so I can also contribute back fixes / new function etc. to the C api? - I've already tried to get some initial stuff up and running with do_postgres but I've hit the following issue: https://gist.github.com/db89903e772d2f112ed2 Especially the conflicting type definition for Size seems problematic. Any idea how I could solve this? I've heard from Matt Aimonetti that the sqlite3 and postgres drivers already work, so if anything has been learned there I'd love to know about it. I subscribed to the mailing list, but also join #ruby-osx on freenode and am available in #datamapper there too. If someone could help me out a bit or point me in the right direction that would be a great help :). -- Regards, Dirkjan Bussink
