#1016: Regular expression 'negative look-ahead' not working properly ----------------------------------+----------------------------------------- Reporter: yasuimao@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: ----------------------------------+----------------------------------------- I'm not sure if I'm doing this properly, but let me try. It's hard to describe, but there seems to be a bug in regular expression negative look-ahead (?! ). The regular expression below might not be optimal, but what it tries to do is a wild card text search for expressions with 0-2 words in between "it is" and "interesting" excluding "not". {{{ text = "It is interesting. It is very interesting. It is very very interesting. It is not interesting. It is not very interesting." p text.scan(/it is(?:\ *(?!\bnot\b)\w+)?(?:\ *(?!\bnot\b)\w+)? interesting/i) }}} Results Ruby 1.8.7/RubyCocoa {{{ => ["It is interesting", "It is very interesting", "It is very very interesting"] }}} MacRuby 0.7.1 {{{ => ["It is interesting", "It is very interesting"] }}} If I don't use negative look-ahead, both return the same array. {{{ text = "It is interesting. It is very interesting. It is very very interesting. It is not interesting. It is not very interesting." p text.scan(/\bit is(?:\ *\w+)?(?:\ *\w+)? interesting\b/i) }}} Result - Ruby 1.8.7/RubyCocoa, MacRuby {{{ => ["It is interesting", "It is very interesting", "It is very very interesting", "It is not interesting", "It is not very interesting"] }}} I also tried this at http://demo.icu-project.org/icu-bin/redemo and the result was the same as Ruby 1.8.7/RubyCocoa. -- Ticket URL: <http://www.macruby.org/trac/ticket/1016> MacRuby <http://macruby.org/>

#1035: ruby subclasses of Obj-C classes have incompatible initialization semantics -------------------------------------------------+-------------------------- Reporter: russm-trac-macports-org@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: #reduction -------------------------------------------------+-------------------------- Ruby classes that inherit from Obj-C classes (including core ruby classes like String) have incompatible initialization semantics compared to mri. Since this affects some core ruby classes, it breaks compatibility between the mri and MacRuby environments. eg: in this subclass of String, S2#initialize is never called with 0 arguments {{{ ru...@alcazar:~$ macruby --version MacRuby 0.7 (ruby 1.9.2) [universal-darwin10.0, x86_64] ru...@alcazar:~$ macirb irb(main):001:0> class S2 < String irb(main):002:1> attr_accessor :foo irb(main):003:1> def initialize foo = "default2" irb(main):004:2> @foo = foo irb(main):005:2> STDERR.puts "setting #{foo}" irb(main):006:2> end irb(main):007:1> end => nil irb(main):008:0> s2 = S2.new => "" irb(main):009:0> }}} while under mri 1.9.2, S2#initialize is called as expected (nb. executable is called irb1.9.1 but is actually 1.9.2 - thanks, Debian package naming!) {{{ ru...@worcestershire/~ 0 $ ruby1.9.1 --version ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-linux] ru...@worcestershire/~ 0 $ irb1.9.1 irb(main):001:0> class S2 < String irb(main):002:1> attr_accessor :foo irb(main):003:1> def initialize foo = "default2" irb(main):004:2> @foo = foo irb(main):005:2> STDERR.puts "setting #{foo}" irb(main):006:2> end irb(main):007:1> end => nil irb(main):008:0> s2 = S2.new setting default2 => "" irb(main):009:0> }}} -- Ticket URL: <http://www.macruby.org/trac/ticket/1035> MacRuby <http://macruby.org/>

#1327: Ruby Constants in Lion -------------------------------------------+-------------------------------- Reporter: harry@… | Owner: lsansonetti@… Type: defect | Status: new Priority: critical | Milestone: Component: MacRuby | Keywords: Lion -------------------------------------------+-------------------------------- I've been trying to test my app on the latest version of Lion (Build 11A459e) with the latest developer preview of Xcode 4 and both the 0.10 and latest nightly build of MacRuby. I've searched both MacRuby.org and apples dev forums but haven't found any reference to whether MacRuby supports Lion yet... but I thought it worth logging this bug. To find it in it's simplest state I started be creating a standard MacRuby app from Xcode's template, and then modified the AppDelegate file so that it looked like the following: class AppDelegate attr_accessor :window Constant_Number = 3 def applicationDidFinishLaunching(a_notification) # Insert code here to initialize your application print "#{Constant_Number}" end end Which produces the following error in the console when the application is run: unknown: warning: already initialized constant DDMap 2011-06-13 19:50:59.987 Io[1011:503] /Users/harry/Library/Developer/Xcode/DerivedData/Io- dqbjbwecwbbpzmbqqzwbrodltwxd/Build/Products/Debug/Io.app/Contents/Resources/AppDelegate.rb:17:in `applicationDidFinishLaunching': uninitialized constant Constant_Number (NameError) from /Users/harry/Library/Developer/Xcode/DerivedData/Io- dqbjbwecwbbpzmbqqzwbrodltwxd/Build/Products/Debug/Io.app/Contents/Resources/rb_main.rb:23:in `<main>' I hope you don't feel this contravenes the NDA.. I don't think it should.. as it's not really revealing anything about Lion. I hope support for Lion isn't too far down the list.
