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

Re: [MacRuby-devel] Building MacRuby with GNU readline support

> I'm trying to get vi-editing mode support in macirb, but it looks this is not going to work without custom build of MacRuby with GNU readline? If you want to avoid building macruby with rl support could try rlwrap in conjunction with macirb (http://utopia.knoware.nl/~hlub/rlwrap/) You can install it through brew, for example. Afterwards, you simply run "rlwrap macirb" and the the console will have full readline support. Hope that helps, Sven

Building MacRuby with GNU readline support
by Mario Grgic 27 Dec '11

27 Dec '11

I'm trying to get vi-editing mode support in macirb, but it looks this is not going to work without custom build of MacRuby with GNU readline? Is it possible to just build readline extension alone and place it in /Library/Frameworks/MacRuby.framework/Versions/Current/usr/lib/ruby/site_ruby/1.9.2/universal-darwin10.0/readline.bundle

Re: [MacRuby-devel] HotCocoa futures

Hi Rich, Thanks for starting a new thread - I was just getting ready to pollute the future of MacRuby thread with some more HotCocoa talk :) Jordan: "The goal of the project is to simplify the process of creating and configuring Cocoa objects used when building native Mac apps" https://github.com/HotCocoa/hotcocoa/blob/master/README.markdown We should probably do a better job of explaining what this means in more detail - I have opened an issue for this here: https://github.com/HotCocoa/hotcocoa/issues/44 Writing more concise code is great, but I wouldn't say it is my primary motivation, here are some other reasons why I use HotCocoa: * It helps you to write clearer and more idiomatic MacRuby code * Express your UI in code rather than IB * Makes it easier to use Xcode alternatives like TextMate * Helps you to package your code * Provides a basic structure for your project Cheers, Isaac On Sat, Dec 24, 2011 at 9:25 AM, Rich Morin <rdm(a)cfcl.com> wrote: > At 7:29 PM +0100 12/23/11, Jordan K.

I had developed quiet a few apps with rb-appscript and I was able to get them all working with the macruby version. A few things needed change but I was able to write apps that used either macruby or MRI versions of appscript. Only a few methods in my "library" code needed to check at runtime which version was being used. > > Steve Would you please provide how you installed object_c-appscript? The rb-appscript manual is rather vague on how to proceed after downloading object_c-appscript. I used rvm to install macruby 0.10.0. Do you know how to change the setup.rb that comes with macruby-appscript to properly install macruby-appscript. Thank you for any assistance you may provide. bbiker

Re: [MacRuby-devel] A Future for MacRuby
by Dan Farrand 24 Dec '11

It's been great to read everyones thoughts on this subject. It's helped me get a better perspective on what MacRuby is. I am a Ruby newbie but have been working on Mac for a long time, mostly in the "business applications" space. Here is my 2 cents. I am very much a Mac fanboy and consequently an Apple advocate. However, I think Apple's weak spot going into the future is Objective-C. I view this issue as somewhat separate from Cocoa, but maybe folks who know more than I do will tell me that they are fused together. I don't actually find it pleasurable to code in Objective-C. There just seems to be too much abstraction, syntax and long rambling class/method names cluttering up the the editor window. I do find Ruby enjoyable to code in. I view Ruby as a way for Apple to provide more accessible pathways for would-be Mac and iOS developers. I had thought this might even have been Apple's idea in supporting MacRuby, But after hearing from everyone, I'm guessing it's more of a "lets keep our options open" attitude and Apples support is real but speculative. There is certainly no indication that Apple sees a problem with it's dependence on Objective-C. The Steve Jobs Apple probably sees it as a big plus because they effectively control the language. If nothing else, it looks like MacRuby is a fun way to poke around inside Cocoa so it's worth pushing into. thanks everyone for taking the time to respond to my original query.

TwUI & MacRuby issue
by isaac kearse 24 Dec '11

24 Dec '11

TwUI is a hardware accelerated UI framework for Mac, inspired by UIKit: https://github.com/twitter/twui I'd like to try using it in my MacRuby apps, so I thought to start with I would port the the TwUI Example Project to MacRuby. TwUI Example Project: https://github.com/twitter/twui/tree/master/ExampleProject MacRuby: https://github.com/isaac/TwUIExample I got a basic version of the example app working, but as I was implementing the tab bar the app crashed with this exception: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x000000000000000a Here is the full crash report: https://gist.github.com/78e7f9870b788e8fd4c9 I have tried to make this crash easy to replicate by writing a Rake task and instructions for installing the TwUI framework for MacRuby - details here: https://github.com/isaac/TwUIExample/blob/master/README.md The app was originally written with HotCocoa, but there is also an Xcode version that reproduces the same crash here: https://github.com/isaac/TwUIExample/tree/master/Xcode I thought this might be related to the fact that TwUI doesn't use garbage collection, but I can also reproduce this crash with a fork that uses ARC here: https://github.com/jspahrsummers/twui/tree/SnowLeopardCompatibility Let me know if I should open a Trac ticket about this, I'm not sure if it is a MacRuby issue or not. Any help would be greatly appreciated! Cheers, Isaac

A Future for MacRuby
by Dan Farrand 23 Dec '11

23 Dec '11

I would like to probe sentiment around the future for MacRuby ? is there a future ? I am drawn to it - I like Ruby as a language and development approach. I appreciate the entrance it provides into Cocoa without having to sign up for Objective-C. But where does it fit within Apple's longer term view ? Is MacRuby about to be Orphaned ? It seems like something happened around march 2011. What are the groups within Apple that hate MacRuby and want to kill it as a threat to Objective-C ? I am loath to invest a lot of time and coding in something that is a dead-end. Would love to hear insights from anyone with better insight.
