Hi, After months of hard work and two successful beta releases, MacRuby 0.5 is now available. Get it here while it’s still hot! MacRuby is a version of Ruby 1.9, ported to run directly on top of Mac OS X core technologies such as the Objective-C common runtime and garbage collector, the CoreFoundation framework and the LLVM compiler infrastructure. While still a work in progress, it is the goal of MacRuby to enable the creation of full-fledged Mac OS X applications which do not sacrifice performance in order to enjoy the benefits of using Ruby. You can learn more about MacRuby, and download a binary installer, from the website: [http://macruby.org](http://macruby.org) Or about this release more specifically, on our blog: [http://www.macruby.org/blog/2010/01/31/macruby05.html](http://www.macruby.org/blog/2010/01/31/macruby05.html) Enjoy, Laurent ---

Anything you can say about MacRuby on the iPad? I’d love to be able to develop full-fledged iPad apps using Ruby. ---

Great! Does it mean that we could build a native Mac application which use a non Apple (i.e. multi platform) library such Qt (cocoa version) or next Tk release with MacRuby? As QtRuby seams not so easy to use (install) on snow leopard, this could be the way to use Ruby with Qt4 or any native installed mac library without hard hacking fot making the binding? But I guess that the call of these libraries will not be multi platform, … – Maurice ---

I just downloaded the new version, and tried the script on the main page(the HotCocoa “Hello world”). It works, but it output this before the 'World!": 2010-02-01 14:22:17.364 macruby[1922:903] \*\*\* -[NSLock unlock]: lock (\ ‘(null)’) unlocked when not locked 2010-02-01 14:22:17.366 macruby[1922:903] \*\*\* Break on \_NSLockError() to debug. Do you have any idea why? ---

I don’t know whether MacRuby would be any advantage here – it might. ## Best, Marnen Laibow-Koser [http://www.marnen.org](http://www.marnen.org) removed\_email\_address@domain.invalid
