0.2 available for testing
by Laurent Sansonetti 18 Jun '08

18 Jun '08

Hi all, Well, after 3 months and a few days of development, 0.2 is now mostly ready to be released. I just merged trunk into the testing branch, please give it a try! $ svn co http://svn.macosforge.org/repository/ruby/MacRuby/branches/testing MacRuby $ cd MacRuby $ autoconf $ ./configure --enable-framework --enable-fat-binary --program- prefix=mac $ make $ sudo make install-nodoc # the `make install' target should now work, but it takes around 15 minutes to generate the RI files, so you might want to skip that step. But at least it should not crash and/or eat all your memory anymore. Unless a big problem is reported, I will release 0.2 next week. In the meantime I will write/port some additional sample code. I also wrote a project roadmap, for the upcoming releases: http://ruby.macosforge.org/trac/wiki/MacRubyRoadmap Some notable 0.2 changes: The String, Array and Hash have been re-implemented using their CoreFoundation equivalent, respectively CFString, CFArray and CFDictionary. For example, String is not a class anymore but a shortcut (alias) to NSMutableString. The whole String interface has been re-implemented on top of NSString. Every string created by MacRuby is therefore a CFString/NSString, and can be passed without any conversion to an underlying API that expects a CFString/NSString. Same thing for Array and Hash. All well-known GC crashers and memory leaks have been fixed. Lots of bugs have also been fixed. irb/erb/rdoc/ri should work! The 1.9 source base was synchronized with the upstream trunk. The new 1.9 APIs introduced since the latest snapshot were implemented. Laurent

Obj-C object allocation and consistency in Ruby
by Brian Mitchell 29 May '08

29 May '08

I've been playing around with objects a bit and have noticed the Objective-C interfaces for object allocation are available. I'm not an regular Objective-C user so this is all from my limited knowledge. In MacRuby, one can currently get away with something like NSCFString.alloc, and it seems to not cause any immediate crashes if init is not called right after. This is a dangerous assumption of course. If I simply try calling on a different class where init is more important it will quickly cause a crash: NSMutableString.alloc.size. In Objective-C the pattern is (AFAICT) usually something like [[MyClass alloc] initOfSomeSort]. It makes sense and the responsibility is on the developer to keep things consistent. In Ruby code however, I would expect these sorts of issues to either be handled or be impossible to occur in pure Ruby. Now there might be a way to handle errors better (i.e. catching the NSInvalidArgumentException in the above example) and prevent bad crashes that currently occur but is this sort of thing just going to become a side effect of living on top of an Objective-C style class hierarchy and protocol? I'd really like to avoid getting segmentation faults and other lower level problems in Ruby code. (Though I don't mind paying the price if this gets to what 1.0 has promised. ;-) ) Thanks, Brian.
