The MacRuby team's busy working towards MacRuby 1.0, recently with the 0.10 release which adds XCode 4 support. Meanwhile, the first applications written using MacRuby have shown up in the Mac AppStore. Also: MacRuby seems to be part of the upcoming "Lion", Mac OS X 10.7.
A whole batch of new Ruby VM releases is available. MacRuby 0.8 fixes bugs and begins the path to 1.0. Rubinius 1.2 improves memory efficiency and the debugger. MRI received new patch levels: 1.8.7-p330 and 1.9.2-p136, the first big bug fix update to 1.9.2.
MacRuby 0.7 is out, with the usual performance and compatibility improvements, including Ruby 1.9.2 compatibility. To demonstrate MacRuby's tight integration with Snow Leopard's Grand Central Dispatch (GCD), the team has released ControlTower, a Rack-based web server. Also: with the new BridgeSupport, all native APIs can now be accessed and scripted.
The LLVM team yesterday released LLVM 2.8, the low-level virtual machine infrastructure that includes a next-generation C/C++ compiler, optimiser, and run-time. In addition, the LLVM also sports a VMKit for CLR and JVM runtime and is used in tools as diverse as MacRuby and Python's Unladen Swallow. Additionally, the recently-released Mono 2.8 has a mono-llvm runtime. So what's new in LLVM 2.8?
MacRuby 0.6 is available now, bringing debugging and vastly improved Grand Central Dispatch (GCD) support. A lot of the core functionality has been overhauled, such as a new String implementation and a new thread-safe Regex library which replaces Oniguruma. MacRuby's now considered stable for Cocoa development.
The first beta of MacRuby 0.5 is available, complete with a new VM, JIT and AOT - and without the GIL. InfoQ talked to the MacRuby core team about the state of MacRuby and whether there'll be a way to write Ruby apps for the iPhone using MacRuby.
MacRuby is nearing its first RC for 0.5 and adds support for Grand Central Dispatch. A new IronRuby release is available, Ruby 1.9.2 might be delayed, and Rubinius joins the group of 1.8.7 compliant Ruby implementations.
A first incarnation of ruby-debug support on 1.9 is now available. Ruby switcher makes it easy to run different Ruby versions in parallel. Also: MacRuby's experimental branch was merged into MacRuby Trunk.
MacRuby is steadily moving forward, with a usable Ahead of Time (AOT) compiler coming closer on the experimental branch, which should make Ruby a first class language for Cocoa applications. Also: a look at Dr Nic's ChocTop utility for creating MacOS DMG files.
MacRuby joins the ranks of JRuby and IronRuby and moved away from Ruby 1.9's Global Interpreter Lock (GIL) in the experimental branch.
IronRuby's alive and kicking - and will go 1.0 in July. We look at some resources to get up to speed with IronRuby's status. Also: JRuby 1.3.1 is an important bug fix update for JRuby users, MacRuby continues to improve and MagLev now comes with a native parser.
New versions of Ruby 1.8.6 and 1.8.7 are available now. JRuby development moves ahead with experiments with running JRuby on IKVM. Also: MacRuby continues performance work and MagLev now runs RubyGems.
The first results of performance work on the next version of MacRuby are now available in an experimental branch. A new VM based on LLVM is used and already shows significant speed improvements over earlier MacRuby versions.
In this presentation from QCon San Francisco 2008, Jason Seifer takes a look at the different Ruby virtual machines (JRuby, MagLev, IronRuby, Rubinius, MacRuby) and how to choose what fits best within the enterprise.
