RoxorReturnFromBlockException*
by Martin Hawkins 31 Mar '11

31 Mar '11

>From what I can read in the archives, this was raised about 18 months ago. Loosely following Matt's book, I've written the following code: def showOpenPanel( sender) openPanel = NSOpenPanel.openPanel openPanel.setCanChooseDirectories( false) openPanel.setShowsHiddenFiles( NSUserDefaults.standardUserDefaults.boolForKey( 'showHiddenFiles')) openPanel.setAllowsMultipleSelection( true) openPanel.beginSheetModalForWindow window, completionHandler: Proc.new{|result| return if (result == NSCancelButton) # throws error } end The result is (on OS X 10.7, MacRuby 0.10), when the cancel button is pressed, uncaught Objective-C/C++ exception... terminate called after throwing an instance of 'RoxorReturnFromBlockException*' Program received signal: “SIGABRT”. sharedlibrary apply-load-rules all Interestingly, on Lion, the output then appears to loop: unable to read unknown load command 0x24 unable to read unknown load command 0x26 unable to read unknown load command 0x24 unable to read unknown load command 0x26 . . Do you need a new ticket?

Hey all, I was just wondering if Laurent or any of the other people involved with MacRuby are planning to be at WWDC. Nick

Creating an Objective-C bundle to use with MacRuby
by Martin Hawkins 29 Mar '11

29 Mar '11

I presume I'm doing something really dopey and apologies if that is the case. I've been following Matt Aimonetti's excellent instructions on the MacRuby site with the above title - I'm attempting to wrap Uli Kusterer's UKKQueue library. I've followed the instructions - the bundle builds ok; it builds 'UKKQueue_engine.bundle' and then I try to 'require' it from the macirb prompt and I get require 'UKKQueue_engine' LoadError: no such file to load -- UKKQueue_engine I've copied the UKKQueue_engine.bundle into the pwd - should I be putting the file somewhere else?

Two changes to Xcode4 templates
by Andre Lewis 29 Mar '11

29 Mar '11

Starting from scratch with the Xcode4 MacRuby application template, I had to make a couple changes for Archiving to work: 1. Project -> Build Settings -> Valid Architectures * change to X86_64 only (remove the i386 default) * if you don't make this change, you get the error "ld: warning: ignoring file /Developer/SDKs/MacOSX10.6.sdk/Library/Frameworks//MacRuby.framework/MacRuby, file was built for unsupported file format which is not the architecture being linked (i386)" when archiving or doing a "build for => archiving" with the Deployment scheme. Building with the non-Deployment scheme would still work. 2. Deployment Scheme -> Edit Scheme -> Build * Add the default target to build before the Deployment target. (so you have two targets building under the Deployment scheme) * if you don't make this change, you get the error "Path does not exist `/Users/andre/Library/Developer/Xcode/DerivedData/Tango-duvzaijhkvprmzdhkzkydcudwljf/ArchiveIntermediates/Deployment/BuildProductsPath/Release/Tango.app'" I'm still getting up to speed on Xcode4 schemes and build settings. Are these changes that should be made in the Xcode4 templates? Andre

I'm having trouble getting the degree symbol ° to display correctly in toolTips and Alert dialogs. Do I need to escape this special character somehow? Thanks, Bob Rice

New guy in town. Advices
by Roberto Perez Cubero 28 Mar '11

28 Mar '11

Hi!! I've been reading the list for almost month(and using MacRuby since 0.2) and this is my first message to the list, so, Hello! To introduce myself I will say I'm a Ruby and OSX enthusiasm, I usually develop in Objective-C and made some incursions in enemy territory using c# and .net :-O Given my passion for Ruby and OSX I think this is the perfect place to live ;). Mixing OSX with Ruby is wonderful, and things like "RSpecing" my ObjC classes seems like science-fiction. I've already compiled the project and have taken and look to the code, and it looks nice. But, now what? I think the priority is to fix the bugs scheduled for 1.0 release, but where are they specified?, and moreover, are they "easy" enough for a "newcomer"?. Which are the recommended tasks for a novice in MacRuby? Hope I will be able to contribute in this project :) Regards. Roberto.

Moving to GitHub!
by Laurent Sansonetti 28 Mar '11

28 Mar '11

Hi guys, We finally decided to move MacRuby's source code repository from subversion to Git, and GitHub seems to be the best place to do it. The move will happen somewhere this week-end, or Monday. The repository address will be: https://github.com/MacRuby/MacRuby. Currently, this repository is a mirror of the subversion one. Here is how we will proceed: 1) Add frequent contributors to the GitHub repository. [Done] 2) Update the nightly build process to use the GitHub repository. [Done] 3) Stop the GitHub repository mirroring. 4) Empty the trunk branch of the subversion repository, and just keep a text file saying that we moved to GitHub. 5) Refresh the website. Once this is done, frequent contributors can commit to the central repository on GitHub, and MacRuby's development can continue. We will keep the rest of the infrastructure (such as Trac for managing the tickets), only the source code repository moves. If you have any suggestion or concern let us know. Also, it's possible that I forgot a step or two, as I'm writing this under the influence of a few guinness :) Hopefully Eloy or Matt will correct me. Thanks! Laurent

Re: [MacRuby-devel] Is HotCocoa dead?
by Michael Gehl 26 Mar '11

I'd like to second the question on HotCocoa status - is it dead, in limbo, quietly flourishing, ???

0.9 update
by Laurent Sansonetti 25 Mar '11

25 Mar '11

Hi guys, 0.9 is now ready to be released! (really!). The trunk branch has been copied as branches/0.9 and we will continue the development on trunk, which now uses the 0.10 version number. It would be nice if you could try the latest nightly build with your app and favorite Ruby lib, and let me know if you find anything wrong, as I had to change (again) the const lookup rules to fix a regression. yesterday. I did a bit of testing and I'm confident the fix is good, but I would prefer to see more testing. http://www.macruby.org/files/nightlies/macruby_nightly-2011-02-22.pkg If I don't hear anything bad, 0.9 will be released Friday :) Thanks, Laurent
