Re: [MacRuby-devel] WWDC ?
by Rich Morin 08 Apr '11

Looking at http://www.sfruby.info/#upcoming, I don't see anything scheduled during WWDC (June 6-10). If the WWDC attendees in the crowd can settle on a date (ideally, one that works for Jordan and Laurent :-), I'll be happy to put in the schedule. I can probably also find a venue for the event; let me know if this is an issue... -r -- http://www.cfcl.com/rdm Rich Morin http://www.cfcl.com/rdm/resume rdm(a)cfcl.com http://www.cfcl.com/rdm/weblog +1 650-873-7841 Software system design, development, and documentation

I want to talk about MacRuby support of Lion.
by Takao Kouji 08 Apr '11

08 Apr '11

Hi, I have joined the "Mac Developer Program". I am compiling and testing MacRuby on Mac OS X Lion Preview 2. I am using CruiseControl.rb to compile and test MacRuby. I want to talk about MacRuby support of Lion (especially icu-1060 directory and auto_zone_1060.h file) with somebody. I think that I can talk if there is it between people joined "Mac Developer Program". Thanks Kouji. --- TAKAO Kouji <kouji(a)takao7.net> blog: http://d.hatena.ne.jp/kouji0625/ twitter: takaokouji / projects: ruby, s7-seven

Apps that look like Twitter Clones
by Keenan Brock 07 Apr '11

07 Apr '11

Hi All, While I have no desire to write a twitter clone, I do feel that many applications are leveraging many UI components from twitter applications like Tweetie. One example that comes to mind is the sparrow email client. While it is heavily inspired by twitter, it is by no means a twitter client. Has anyone stumbled across any good reads out there that walk through creating the various visual elements of a twitter client? The main twitter feed with the various hotspots, icons, colors, images. Theming the main feed. Making the icon bars I'm currently trying to leverage the following 3 articles, but was hoping people may have some other pointers. http://isaac.kearse.co.nz/2010/01/10/async-table-views-with-macruby/ http://flyosity.com/mac-os-x/clickable-tweet-links-hashtags-usernames-in-a-… http://perspx.com/archives/making-list-views-really-fast/ Thanks, Keenan

Bug in string comparison?
by Mark Rada 07 Apr '11

07 Apr '11

I've got a strange behaviour during string comparison that boils down to the following: class NSString def predicate? [-1] == '?' end end puts '?'.predicate? # => false puts '?'[-1] # => "?" puts '?'[-1] == '?' # => true I'm not sure if this is a known side effect of how Strings are implemented now or if it is simply a bug. I know it will work if I use a regexp, but this method is less code and faster. Thoughts? Thanks, Mark Rada mrada(a)marketcircle.com

Tyro Needs Ruby vs. O-C Advice
by Bryan Harrison 07 Apr '11

07 Apr '11

I've decided to use an upcoming sabbatical to teach myself OS X and iOS programming. My background includes OS X systems administration and web development, mostly using the Apache/MySQL/PHP model. I'm familiar with OOP concepts and have trifled with any number of languages from C to AppleScript, but am not fluent in any object oriented language. I've been exploring Xcode 4 for a week and feel conversant with the IDE if not yet able to accomplish anything with it. So… I understand that Cocoa is a given, but today's million dollar question is Objective-C or MacRuby? I'm a blank slate with regard to both and so could use some good advice. For example… What are the advantages of MacRuby over Objective-C? What are the advantage of O-C over Ruby? Is Xcode's support for O-C significantly better than it's handling of Ruby? Do I care? At this point I'm primarily interested in OS X development, but iOS clearly needs to run a close second. What's the current status of Ruby development for iOS and is it likely to go anywhere in the nearish future? Any thoughts on the longer-term prospects of either language? Any thoughts from anybody will be much appreciated. Thanks, Bryan

Computer Serial Number
by Robert Rice 06 Apr '11

Hi Gang: Could anyone help me to read the computer's serial number from a MacRuby program. Since I don't know Objective C, I haven't been able to figure out how to access it. Thanks, Bob Rice

[ANN] TrackerBot 1.0 in App Store -- tested with MacRuby!
by Christian Niles 06 Apr '11

06 Apr '11

Hey All, One of the reasons I've gotten so in love with MacRuby is that it's let me BDD my Cocoa projects, in particular an app I just released to the App Store, called TrackerBot [1]. TrackerBot is an iPad and iPhone interface to Pivotal Tracker, the well-known agile project management tool [2]. While I can't run my MacRuby/RSpec2 specs on the actual device, I've ben able to move a majority of my code into an iPhone compatible framework that I do test with MacRuby. I'm beginning to use Frank for UI automation tests on the device and am developing a gem that tries to make all the XCode configuration and setup painless for new users who want to get started with MacRuby/XCode/Cocoa development. So, in addition to the release announcement, I just wanted to thank you all for making it possible to use all the Ruby BDD tools I love with Cocoa. It has made me far more productive, and the development far less frustrating. Thanks! christian. [1] http://vulpinelabs.com/trackerbot [2] http://www.pivotaltracker.com/

XCode 4 -- I Must Be Missing Something
by steve ross 04 Apr '11

04 Apr '11

I was using XCode 3 and everything was a breeze, but a new MacRuby project in XCode 4 seems like pulling teeth. I'm sure someone has run across this, so I'll ask. I read Matt's chapter on XCode 4, read the redwoodapp.posterous.com article on setting the targets, and can get the thing to run and the main window to display. So here's the proble: I have a Ruby class, ApplicationController, and I've hooked one button, one label, and one slider to it using IB. I declared the outlets as attr_writer and the method signature for the action is on_randomize(sender). I created an awakeFromNib method. In this method, I put: puts "hello, world" It never prints to the console. Main window displays fine. No puts. I changed the File's Owner to ApplicationController (although it shouldn't matter, because it's not document-oriented). Still nothing. I added puts statements to app_delegate.rb and nothing there is being executed. I added puts statements to rb_main.rb and it is being loaded, and the Ruby files are being required. The only build error is as follows: 2011-04-04 16:08:53.742 Random Password Generator[79326:903] loaded rb_main 2011-04-04 16:08:53.751 Random Password Generator[79326:903] requiring AppDelegate 2011-04-04 16:08:53.756 Random Password Generator[79326:903] requiring ApplicationController 2011-04-04 16:08:53.805 Random Password Generator[79326:903] Could not connect the action on_randomize: to target of class ApplicationController The first 3 lines are my debug statements in rb_main.rb. The third one, "Could not connect..." is the one I'm having trouble interpreting. Any pointers as to why my code simply doesn't hook up?

Noob Learning with Xcode 4 and 10.6 SDK
by Tim Case 04 Apr '11

04 Apr '11

I'm brand new to Macruby and having trouble getting started at even the "Hello World" level. I have the Macruby Peepcode screencast and the beta version of the MacRuby version for O'Reilly. What I've found is that XCode 4.0 is dramatically different then what I saw with XCode 3.0 in the screencast so I'm having trouble following along with the tutorial. Additionally, I also ran into problems trying to run Matt Aimonetti's sample code at https://github.com/mattetti/MacRuby--The-Definitive-Guide.git. I ran into "missing base SDK 10.5", I have 10.6 not 10.5. Can someone suggest a learning strategy with the best available tutorial/documentation? I'm guessing I should try learning with XCode 3.0 because XCode 4.0 is still too new right now?
