by Vincent Isambart 17 Sep '09

17 Sep '09

Hi, Just to say I uploaded my RubyKaigi 2009 slides on slideshare: http://www.slideshare.net/vincentisambart/rubymac The presentation was entirely done in Japanese (with someone translating in English on IRC) but the slides are bilingual Japanese/English The video is also available on Ustream but there is no translation and you will only see the screen, not me presenting: http://www.ustream.tv/recorded/1833285 PS: Yes I know it was two months ago, but well nobody asked for my slides so I did not take the time to upload them :P. Cheers, Vincent

unrecognised defined?
by Ben Schwarz 17 Sep '09

17 Sep '09

Hey folks, After installing the 'grit' gem I required' it in macirb and received the following: ben@Homeslice ~ Ϟ macirb irb(main):001:0> require 'grit' unrecognized defined? arg: 21 (NODE_AND)fish: Job 1, 'macirb' terminated by signal SIGABRT (Abort) Which, I believe is responding to line 12 in grit.rb – http://github.com/mojombo/grit/blob/master/lib/grit.rb#L 12 Is this a bug that should be logged? I've tried defined? RUBY_ENGINE in macirb and it appears to execute without a problem Cheers, -- Ben Schwarz Web architect Web: http://www.germanforblack.com -- Please consider your environment before printing or distributing this material. --

objc block and ruby block?
by Linan Wang 17 Sep '09

17 Sep '09

Hi, I'm playing with the new block syntax of objc recently. I tried to call a ruby block from an objc block-ish methods but failed. The code snippet: @implementation BlockTest ... -(void)testBlock:(void^(int i))block { block(self.x); } ... @end; MacRuby codes: b.testBlock do |x| puts x end Anything wrong with my codes? or it's not supported yet? (if so, any plan to do it?) Best wishes Linan

[MacRuby] #335: Top-level RDoc for gcd.c
by MacRuby 17 Sep '09

#335: Top-level RDoc for gcd.c ----------------------------------------+----------------------------------- Reporter: ernest.prabhakar@… | Owner: lsansonetti@… Type: enhancement | Status: new Priority: blocker | Milestone: MacRuby 0.5 Component: MacRuby | Keywords: gcd ----------------------------------------+----------------------------------- Here's some proposed language for: http://svn.macosforge.org/repository/ruby/MacRuby/trunk/gcd.c // TODO: Add a top-level rdoc for the module explaining what GCD // is good for (and pointing them to the dispatch(3) manpage). ========== Grand Central Dispatch (GCD) is a novel approach to multicore computing that is built into Mac OS X version 10.6 Snow Leopard. In particular, GCD shifts responsibility for managing threads and their execution from applications to the operating system. This allows programmers to easily refactor their programs into small chunks of independent work, which GCD then schedules onto per-process thread pools. Because GCD knows the load across the entire system, it ensures the resulting programs perform optimally on a wide range of hardware. GCD is built on a highly-efficient multicore engine accessed via a C API providing four primary abstractions, which are wrapped in this MacRuby implementation: ▪ block objects ▪ dispatch queues ▪ synchronization services ▪ event sources For more information, see the dispatch(3) man page. -- Ticket URL: <http://www.macruby.org/trac/ticket/335> MacRuby <http://macruby.org/>

trunk status update
by Laurent Sansonetti 16 Sep '09

16 Sep '09

Another status update about the development of MacRuby. The last update was about a month ago, I'm sorry about that. A lot of things happened since, but this status only covers visible points. The upcoming status updates will be more detailed :) - A lot of StringIO work was done. - Added a new optimized Array class that is used for default allocations. The array is a subclass of NSMutableArray but is faster in our benchmarks and is able to efficiently deal with primitive types. - Added an NSDocument-based Xcode project template, offered by James Granby. - Marshal is mostly implemented. - Added support for several missing Ruby method features (such as method visibility and scope). - Added support for the following extensions: etc, fcntl, socket, zlib. Fixed a lot of bugs in YAML. - Fixed a lot of bugs in instance_eval & friends. - Improved the AOT compiler: added support for missing literals and compilation of shared loadable objects. The compiler is able to compile irb. - Added an API that covers the GCD (Grand Central Dispatch) feature of Snow Leopard. The API is mostly stable modulo a few crashers. Documentation is available in the gcd.c source file as RDoc comments. Specs are being written. - RubySpec was updated from upstream. - Started the migration to LLVM 2.6. The work is in a branch called llvm26 and should work modulo a few well known problems. It will be merged soon. - Re-implemented the IO layer to not use CFStreams anymore. These were slow, too complex to use and we had to work around too many problems. - Added partial support for RubyGems. This is a work in progress, but macgem should be able to install gems. - A lot of less-visible bug fixes and optimizations that are not covered here because there are too numerous and I'm a very lazy person. - Claudio Poli contributed a web application that periodically builds binary installers of MacRuby trunk. It is available here: http://macruby.icoretech.org . Feel free to use this in case you want a simpler way to follow trunk. Please note that these installers won't work on Mac OS versions below 10.6 (Snow Leopard). We are smoothly converging for the 0.5 release and the goal is now to deliver a release candidate. Our objective for the first RC is to have a fully working rubygems and also implement critical missing features (such as backtracing, symbolication and some remaining Binding bugs). We expect to deliver it in about 2 weeks (maybe less :)). Laurent

Static C-Arrays
by Tom Kleber 10 Sep '09

10 Sep '09

Is it possible to create static c-arrays in macruby? In jruby Array has a a #to_java method which converts a Array object to an java array (a = Array.new(6).to_java(:double)) Is there something like that supported in macruby? Tom
