Document based application template
by Andy Stechishin 31 Jan '12

31 Jan '12

I am trying to make a Document based MacRuby application. I create the new project in Xcode4 (4.0.2) and immediately select build and run. The application starts but there is no "Untitled" window and the File->New and File->Open menu options are greyed out. Following the same sequence of actions except choosing an Objective-C based application, the "Untitled" Window appears and the menu options are active. I have compared the project contents, the xib files (including File Owners and First Responders) and linked frameworks and can find no difference that would explain the different operation. It would seem that there is some problem with NSDocumentController in the MacRuby version. It is either not there or has been added properly to the responder chain. Am I missing something? Or is this a defect? Has anyone else encountered this and found a work around? Andy Stechishin

How to Configure Xcode to Run Test in MacRuby Project?
by techzen 05 Nov '11

05 Nov '11

Okay, I'm sure I'm just missing something simple but I can't figure out how to include test in a MacRuby Xcode project. I've been using MacBacon to learn MacRuby in TextMate but I don't see how to do so in Xcode. My google-fu has failed me as well because all the example are how to include MacRuby test in an Objective-C project and the build settings don't seem to translate to a pure MacRuby project. It looks to me like I would have to build a custom testing bundle from scratch for each project but that can't be correct. Any pointers would be appreciated. I don't know much ruby so I'm sure I'm missing something. TechZen

Scripting Bridge
by Spencer Rose 01 Nov '11

01 Nov '11

Hey everyone, any help would be incredible. I am consolidating a workflow with scripts into an actual desktop application. When a search down to base "leaf" node such as "AppliedFont" from a paragraph style in InDesign, all I get is a SBObject. I need the name of the font. I am struggling to figure out how to introspect that object. Tried casting it, to inspect as a Cocoa object. Did not go well. Anyways, any ideas on how to get the property names and not these SBObjects would be helpful.

Re: [MacRuby-devel] brace yourselves, 0.11 is coming!
by Steve Clarke 25 Oct '11

Hi, I installed 0.11 using the installer pkg. The install seemed to work fine. However, when I run my app I get a message that wasn't there with 0.10 or with an earlier build of 0.11. Here's the console message: Membership(4727,0x1043bf000) malloc: *** auto malloc[4727]: error: GC operation on unregistered thread. Thread registered implicitly. Break on auto_zone_thread_registration_error() to debug. I see that there's a closed "won't fix" ticket for a similar problem, so I guess this is not related to the installer. I'll just live with it unless it's of interest to anyone else. Steve

MacRuby app store guide
by Rob Ista 25 Oct '11

25 Oct '11

Yes, i do always. Submitting without manually code signing does not work anyway … My SubtitleResync App is already a few months in the store and I regularly submit releases with manual code signing approx according to the procedure of Elliot. That worked fine until last week when I submitted another app. Elliot is right, as you can read in the response from the review team, "your app has proceeded to review, but . . . .

Advice for Total Tyro
by Bryan Harrison 24 Oct '11

24 Oct '11

Older & Wisers: Having done enough web development, network design, and systems administration for one lifetime, I've decided this winter is a fine time to leave all that behind and become an applications developer. Wanting to make consumer products and having no interest in Windows, most of the territory ahead is obvious. But still, I'd appreciate some advice from those who're already there, particularly with regard to MacRuby. Specifically, has development for OS X and iOS reached the point where it would be reasonable to pursue Ruby before or even instead of Objective-C? I've modest C background, am OOP-familiar, am not versed in Cocoa, and am only marginally familiar with Ruby. Obviously I'd like to get up to speed as soon as possible, but I'm not under any pressure and expecting this will be the next 5-10 years of my life, would rather be good than quick. Objective-C is not without a certain homely charm, but Ruby is obviously the more modern language. So… Does Xcode treat Ruby as family, or is it a stepchild toiling in the ashes? Are there other tools I'll need? What's Apple's attitude toward Ruby applications? Can Ruby take advantage of the (finally!) modern memory management features released with iOS 5? Will I end up have having learn Objective-C regardless? Basically, "If you were me, what would you do, and what order might you do it in?" Thanks, Bryan

I don't know if this is a xcode bug .. I'm still developing on SL with xcode 4.0.2 because Lion and 4.2 gives me too much trouble and crashes. The automated response in the review process about the codesigning is quite new and I have not seen it before (on the same delvelopment machine with the same tools) until recently when submitting a new macruby app. It complaints about the macruby framework itself, all .rbo and .dylib files from the framework and all app-specific .rbo files from the deployment phase of the app. It worries me a bit because it seems to shut the door to macruby apps in the near future. It 's now only : Dear Developer, We have discovered one or more issues with your recent binary submission for "SMSReCall". Your app has proceeded to review, but the following issues should be corrected in your next submission: Invalid Signature - the nested app bundle Ruby (SMSReCall.app/Contents/Frameworks/MacRuby.framework) is not signed, the signature is invalid, or it is not signed with an Apple submission certificate. Refer to the Code Signing and Application Sandboxing Guide for more information. Invalid Signature - the executable SMSReCall.app/Contents/Frameworks/MacRuby.framework/Versions/Current/usr/lib/libmacruby.1.9.2.dylib is not signed, the signature is invalid, or it is not signed with an Apple submission certificate. Refer to the Code Signing and Application Sandboxing Guide for more information. Invalid Signature - the executable etc etc etc Rob - - - - Thanks for sharing Eliott, that seems to be a bug with Xcode and it should be affecting all 3rd party frameworks, not just MacRuby. Quite strange, but thanks for showing how you worked around the signing problem. - Matt On Wed, Oct 19, 2011 at 11:23 AM, Elliot Temple <curi at curi.us> wrote: > http://curi.us/1538-macruby-and-the-mac-app-store > > Got my game in the app store.

Concurrency bug in ControlTower
by Charles Oliver Nutter 23 Oct '11

23 Oct '11

Apologies reporting this here; I'm not sure where I should report bugs in ControlTower. I believe there's a bug in ControlTower around line 34: def open @status = :open while (@status == :open) connection = @socket.accept # << here @request_queue.async(@request_group) do The "connection" local variable is used in the async block below to parse the request and send the response. Unless MacRuby's blocks behave differently than regular Ruby, this variable is shared across all activations of that block. As a result, it's possible that two concurrent requests will end up using each others' connection, and usually just blowing up as a result. The fix I've come up with is to wrap the @request_queue.async call in a tap call: def open @status = :open while (@status == :open) conn = @socket.accept conn.tap do |connection| @request_queue.async(@request_group) do Since async can't accept any explicitly-passed state, this seems like the safest way to ensure the connection reference is not shared by separate invocations. I'm not sure if it's possible in GCD, but having async take an optional argument with explicitly-passed state might also be a good way to fix this. - Charlie

Mailing list hosting (was: thread-safety and collections in macruby)

> Hmm thanks, I didn't realize we had a google groups mirror. I'm wondering if we shouldn't just move there since it's much easier to use and maintain than macosforge. > Thoughts, ideas, suggestions? I'd personally prefer that a lot over a mailing list! In trying to work around this, I've turned off mails from the list and subscribed to the group's RSS feed but that makes posting difficult as you have to copy-paste stuff from the google group to a mail reply.

thread-safety and collections in macruby
by Michael Johnston 22 Oct '11

22 Oct '11

In ObjC, the immutable collections are threadsafe. In macruby, are collections threadsafe to read only? ie, if I do this: a = [ ...] # an array that may or may not be changed b = a.dup # nowhere in the code is b ever used to add/delete/change an element is b thread-safe to read from multiple threads (queued operations/blocks)? also, is there any difference between doing b = a.dup and b = NSArray.arrayWithArray(a) Both result in class Array, so I assume there is no difference. Cheerio, Michael Johnston lastobelus(a)mac.com
