[MacRuby] Simple embedded WEBrick?
by Alexander von Below 03 May '10

03 May '10

Hello, I am new to MacRuby, and new to this list, so first a "Hello"! Secondly, I am trying to start a simple WEBrick in a Ruby App. The WEBrick code is a sample from a book, and runs fine if started on its own. But when I evaluate the file in MacRuby within my Cocoa App, a call to http://localhost:2000/hello yields "Bad Request". Furthermore (as to be expected), the script does not return. I am happy creating a separate thread for the Ruby Evaluation in my Cocoa App, but is there a better way? My sample project is hosted here: http://github.com/below/RubyTest I would be very thankful if someone could have a look (and I am sure others will find this useful information, too) Thanks a lot! Alex

[MacRuby] #673: macruby_main() should always ignore RUBYOPT

#673: macruby_main() should always ignore RUBYOPT -----------------------------------+---------------------------------------- Reporter: lsansonetti@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: -----------------------------------+---------------------------------------- It is common for Ruby users to define RUBYOPT to "-r rubygems" in their default environment profile. However, in the case of the Cocoa application embedding the MacRuby runtime, the initialization process will fail because rubygems is not in the path. Therefore, macruby_main() should never take RUBYOPT into account. -- Ticket URL: <http://www.macruby.org/trac/ticket/673> MacRuby <http://macruby.org/>

0.6 almost there, need help!
by Laurent Sansonetti 03 May '10

03 May '10

Hi guys, 0.6 is now almost there. I need to polish a few more things and prepare a detailed blog post about what changed. A lot of things changed in fact, it's going to take some time :-) For this release, we would like to announce that MacRuby is now stable for Cocoa development. If you are working on a MacRuby Cocoa app, it would be awesome if you could try the latest nightly build (or build the sources by yourself), and let us know if everything is good for you, or not. I am going to do a pass on the tracker to identify outstanding bugs that haven't been fixed yet, but if you filed one do not hesitate to remind me! Thanks :) Laurent

[MacRuby] #671: MacRuby developers can't know if their arrays are mutable or immutable
by MacRuby 03 May '10

#671: MacRuby developers can't know if their arrays are mutable or immutable -------------------------------------+-------------------------------------- Reporter: mattaimonetti@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: MacRuby 0.6 Component: MacRuby | Keywords: -------------------------------------+-------------------------------------- The following code will raise an exception: {{{ [1,2,3].copy << 4 }}} The reason why is because Array implements NSCopy and calling #copy on a mutable array will return an immutable version. So everything is normal, the only problem is that since the 0.6 Array rewrite, one can't figure out if his array is mutable or not: {{{ NSArray.arrayWithObjects('terrans', 'zerg', 'protoss', nil).class => Array NSMutableArray.arrayWithObjects('terrans', 'zerg', 'protoss', nil).class => Array NSMutableArray.arrayWithObjects('terrans', 'zerg', 'protoss', nil).copy.class => Array [1,2,3].class => Array ruby-1.9.1-p243 > [1,2,3].copy.class => Array ruby-1.9.1-p243 > [1,2,3].copy.frozen? => false }}} -- Ticket URL: <http://www.macruby.org/trac/ticket/671> MacRuby <http://macruby.org/>

How to get elements from Boxed object
by Craig Williams 03 May '10

03 May '10

This works in Objective-C but in MacRuby I cannot find a way to access the properties of the Boxed object that is returned by loc.coordinate in the code below. Thanks, Craig MacRuby Version 0.7 -> pulled today OS -> 10.6.3 Objective-C version: CLLocation *loc = [[CLLocation alloc] initWithLatitude:38.0 longitude:-122.0]; NSLog(@"Lat: %.2f", loc.coordinate.latitude); NSLog(@"Long: %.2f", loc.coordinate.longitude); [loc release]; // Result: // 2010-04-30 16:48:55.568 OCCoreLocationTest[70030:a0f] Lat: 38.00 // 2010-04-30 16:48:55.570 OCCoreLocationTest[70030:a0f] Long: -122.00 The loc.coordinate is a CLLocationCoordinate2D struct. typedef struct { CLLocationDegrees latitude; CLLocationDegrees longitude; } CLLocationCoordinate2D; MacRuby version: framework 'corelocation' loc = CLLocation.alloc.initWithLatitude(38.0, longitude:-122.0) # => #<CLLocation:0x20004c4e0> puts loc.class # => CLLocation puts loc.description # => <+38.00000000, -122.00000000> +/- 0.00m (speed -1.00 mps / course -1.00) @ 2010-04-30 16:37:47 -0600 puts loc.horizontalAccuracy # => 0.0 puts loc.verticalAccuracy # => -1.0 puts loc.timestamp # => #<__NSCFDate:0x20005ff40> puts loc.coordinate # => #<Boxed:0x2000af7a0> puts loc.altitude # => 0.0 puts loc.coordinate.longitude # => Error:in `<main>': undefined method `longitude' for #<Boxed:0x2000b7660> (NoMethodError)

Cannot get standalone distribution to work with 0.5 or Apr 29 nightly
by Brian Marick 03 May '10

03 May '10

I'm trying to get a standalone distribution working (one with the MacRuby framework embedded in the app). I've followed the instructions in the tutorial http://www.macruby.com/documentation/tutorial.html and also looked at the discussion in ticket 281, macruby-devel at http://bit.ly/dkKyXT, and carlo.log http://bit.ly/5SdxCq At this point, the app does nothing but pop up "hello world" (using Cocoa directly rather than via hotcocoa). It fails with this message in the console: no such file to load -- ubygems (LoadError) ubygems.rb *is* present in the path that rb_main.rb sets, but the error happens before rb_main.rb is entered. I've tried using install_name_tool in various ways, but it never changes anything. Questions: 1. Is the LoadError caused by something else entirely? 2. Should I need to use install_name_tool with recent nightlies or is macruby_deploy all I should need? 3. Any ideas about how to make it work? ----- Brian Marick, independent consultant Mostly on agile methods with a testing slant Author of /Programming Cocoa with Ruby/ www.exampler.com, www.exampler.com/blog, www.twitter.com/marick
