MacRuby & MountainLion + what you can do to help the project
by Matt Aimonetti 19 Feb '12

19 Feb '12

Hey guys, A few of you asked me privately and publicly what was going on with MacRuby releases and what was the plan now that Apple clearly said that ARC is the future and that the GC will be deprecated in MountainLion. First off, I want to emphasis that even though ARC is the future for iOS and OS X, the GC won't go away anytime soon. In other words, MacRuby runs on MountainLion, so there is no real rush. But we need a plan and that plan probably means not using the GC anymore :p Regarding MacRuby's releases, Laurent promised to push 0.11 and well, we are waiting on him but it should happen any day now<https://twitter.com/lrz/status/170464894154584064>;) Allan Delacruz, a designer friend of the project did a redesign of the site but we need some help to rebase and polish the content. Volunteers please stand up, Allan's branch is there: https://github.com/AllanD/MacRubyWebsite Maybe someone can find some time over President's day to give us an updated website? Don't hesitate to email the mailing list about that. Xcode 4.3 It was reported that because Xcode is now a normal app, our templates aren't installed in the right place. We need a few volunteers to modify/test our installer to support the older and the newer Xcode. Or maybe we can just agree to only support the latest Xcode version (thoughts?) Extra ideas for volunteers: - Changelog for 0.11 release, let's help Laurent writing the release blog post by giving him a summarized changelog - Sublime Text 2 http://www.sublimetext.com/ is the new TextMate and I quickly looked at it and adding MacRuby support seems really straightforward (requires some Python scripting but hey, that's better than dealing with AppleScript :p). My challenge to you is to offer a MacRuby/Cocoa package. - Organize the various samples we have and add them to the website. - Update the tutorials (linking to the online version of my book is fine but original stuff should be encouraged, especially what I missed in the book) - Document the MacRuby internals and help new devs contribute feature and fix bugs. Summary: the sky isn't falling, we are all good but we need help and we need to grow the team of active contributors. Tell us what you are interested in helping with and let's get organized to push MacRuby to the next level. Thanks, - Matt

contributing to the website
by Matt Aimonetti 18 Feb '12

18 Feb '12

Here is the tutorial we have on the website: http://www.macruby.org/documentation/website-contributions.html I just added a .rvmrc file and a Gemfile (bundler) so anyone should be able to run webby to build the site locally https://github.com/MacRuby/MacRubyWebsite/commit/adbc7a2713e0ffcb2656da8370… My fork: https://github.com/mattetti/MacRubyWebsite should have the new design stuff from Allan (not fully finished) and the content from master. Thanks, - Matt

AppleTV mirroring?
by hamin 14 Feb '12

14 Feb '12

Hey Guys, I know that from iOS devices you can mirror to an AppleTV with custom views and sounds. I was wondering if it was possible to do that in macruby somehow? I know about the airplay hacks which allow you to play media on an AppleTV but I don't just want to play a media file, but actually show a custom view. Any thoughts? Haris

Show MacRuby? - a start...
by Kevin Poorman 12 Feb '12

12 Feb '12

Good day, I am a huge fan of the hard work that all of you have put forth to bring MacRuby where it is today. I have been using it on and off over the past 3 months for client work and have come across a few things that I often need that are in some way obscure / hard to find / under-documented, or -- mostly -- cocoa design patterns and ideas that are completely foreign to this rubyist. I wanted to try and contribute something to this project and as such, I've started a public repo of "Recipes" of MacRuby tasks / activities that were "hard fought." I am under no delusions that they are perfect, and welcome additions, refactorings and ridicule. But it's a start. Without further ado, http://code.pinguinshow.com/macruby-recipes/src Currently it contains "recipes" for: - Populating a NSCell based Table View - Downloading a file while displaying a progress indicator in a sheet - Opening the file/directory choosing sheet and handling the response Coming soon it will contain recipes for: - consuming scripting bridge files - Core Data (probably quite a few here) - bootstrapping sinatra (awaiting a bugfix in macruby) Please feel free to fork, and send pull requests etc. Lets make it awesome!

Rubygems version
by Gabriel Gilder 08 Feb '12

08 Feb '12

Hi, just wondering if there are plans to bring the version of Rubygems that is bundled with MacRuby up to date any time soon. The current version with MacRuby 0.10 is Rubygems 1.4.2 -- quite a bit behind standard Rubygems, which is at 1.8.15. This becomes a problem when certain gems are configured to only install on fairly recent versions of Rubygems... Thanks, -Gabriel

Interface builder
by Dave Baldwin 08 Feb '12

08 Feb '12

Just got back to using MacRuby and trying to write an app. I use Textmate and rake to edit my code files and build an app and this works very well for me. With the earlier versions of IB you could just manually add the outlets and actions but I am at a loss as to how to do this in IB4 manually or even how to get IB to scan my Ruby files. I suppose I could make a fake xcode4 project with my Ruby files in it but this seems a bit of an overkill just to get IB to know about my actions and outlets. Any help or suggestions appreciated. Dave.

MacRuby + MAS = Invalid Signature
by Daniel Westendorf 01 Feb '12

01 Feb '12

If you've been submitting applications to the Mac App Store, you've probably seen errors about files or your App having Invalid Signatures. The solution is to use codesign to fix this. As of this pull request https://github.com/MacRuby/MacRuby/pull/52#issuecomment-3745546, macruby_deploy now fixes this with a --codesign switch that requires the name of your signing certificate. Hopefully this saves some people a little greif. Daniel

How to debug MacRuby crashes?
by Marc Abramowitz 01 Feb '12

01 Feb '12

I've discovered that it's not difficult to make MacRuby crash by doing things that it doesn't like. Unfortunately, I'm a MacRuby novice and I'm making a lot of mistakes and I don't always know what they are and it seems difficult to figure out from the crash messages. For instance, right now I'm running my app from Xcode and every once and a while I get an intermittent (probably a concurrency-related bug involving run loops, timers, and the like) crash: *Assertion failed: ((size_t)pos < current_exceptions.size()), function pop_current_exception, file vm.cpp, line 3596.* >From a little big of digging around, I gather that this is probably coming from: RoxorVM*::*pop_current_exception https://github.com/MacRuby/MacRuby/blob/master/vm.cpp#L3600 This happens in the app's main thread in the com.apple.main-thread (serial) queue. My app is running in thread 3. I still don't know what that means though :-) Perhaps my code triggered some kind of exceptional condition? There is very little info in Xcode. Lots of warnings about missing debug information -- e.g.: warning: Could not find object file "/Users/lrz/src/macruby-master/ext/json/parser/parser.o" - no debug information available for "parser.c". ... I'm on OS X 10.6.8 and I believe that my app is running with the MacRuby 0.11 release from https://github.com/downloads/MacRuby/MacRuby/MacRuby%200.11.zip (BTW, is this a "blessed" release? I noticed that GitHub has this 0.11 version, but macruby.org still lists 0.10 as the current version). $ macruby -v MacRuby 0.11 (ruby 1.9.2) [universal-darwin10.0, x86_64] I imagine that I might be able to eliminate these by compiling MacRuby (and LLVM) from source? Is this likely to help? Will this give me clues about what I did wrong in my Ruby code? Or is there some other way to diagnose what's wrong? Perhaps a .dSYM file would help? Thanks, Marc
