MacRuby Description

A version of Ruby, ported to run directly on top of Mac OS X core technologies MacRuby is a version of Ruby, ported to run directly on top of Mac OS X core technologies such as the Objective-C common runtime and garbage collector, and the CoreFoundation framework. Even though it is still a work in progress, MacRuby has the main goal 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. What's New in This Release: · This is quite an important release that brings new features and fixes several problems. The changes are too numerous to be all mentioned, so here is a selection of the most interesting ones. Threaded GC: · The MacRuby garbage collector is now running in multi-threaded mode by default. That means that MacRuby will always do garbage collections on a separate thread and therefore not interrupt the program's flow. Full 64-bit Support: · MacRuby is now fully working in both Intel 32-bit and 64-bit modes. If you are running a recent Mac chances are that it is 64-bit and MacRuby will run faster on it. This is mainly due to the fact that the underlying infrastructure has been significantly improved for 64-bit processors. DTrace Probes: · DTrace probes have been added to the core of the interpreter. You can now trace various things such as method calls or exceptions. All of that can be done on any MacRuby processes in the system. · DTrace is a very powerful tool that has proven to be extremely useful when debugging live applications. MacRuby ships with several DTrace scripts in /Developer/Examples/Ruby/MacRuby/DTrace to profile various things such as method count, duration or even objects collected by the GC. Runtime Objective-C API: · MacRuby now exposes an Objective-C API that can be used to control the runtime from a pure Cocoa environment. · It should be helpful if you are working on an Objective-C Cocoa application and are considering using MacRuby to either implement new functionalities or to provide a scripting interface to your native objects. New Xcode Templates: · A "MacRuby Core Data Application" template is now available, as well as an "Embed MacRuby" target. The latter can be used to embed MacRuby.framework inside your application bundle. Embedding the framework allows you to distribute your application to users and not require them to install MacRuby. A Better HotCocoa: · HotCocoa is a thin, idiomatic Ruby layer that sits above Cocoa and other frameworks. It was introduced in MacRuby 0.3 and it has been significantly improved in 0.4. · New mappings for XML parser, KVO array/set accessors, property lists and more AppKit components were added as well as lots of bug fixes and improvements. · A "deploy" task was added to the project's Rakefile. This new task prepares an application for deployment by embedding the MacRuby runtime inside its bundle (similar to what the Xcode's Embed MacRuby target does). Once the "macrake deploy" task is complete, you can share your .app with friends who do not have MacRuby installed on their machine. · But the most interesting change is probably the new graphics layer, called HotCocoa::Graphics. It provides a simple object-oriented interface into the power of Mac OS X's Core Graphics and Core Image drawing libraries. Misc Changes: · Over the list of minor changes, Set has been reimplemented on top of NSSet and NSNumber implements the Numeric methods. Finally, the standard library was updated to Ruby 1.9.1's version. Caveat Lector: · While MacRuby 0.4 turns out to be pretty stable when it comes to Cocoa development, there are still a few problems with C extensions, RubyGems and Ruby IOs. We recommend to use the corresponding Cocoa APIs (when they exist) in the meantime we work on these issues.
