[MacRuby][0.5] Which version of rake version to use?
by Conrad Taylor 05 Jul '09

05 Jul '09

Hi, I was wondering, which version of rake should one use to build and run the specs/benchmarks with? I ask this questions because my default points to /opt/local/bin/rake which is the version that's parts of my MacPorts install of Ruby 1.9.1p129. Also, I noticed that there's a version called macrake which generates the following error on execution: Segementation fault -Conrad

Re: [MacRuby-devel] Regexp possible bug

Sorry, the AT was escaped, another similar example is: puts ("aA0ƒz" =~ /\x41/).inspect searching for the uppercase A.

Regexp possible bug
by Renzo Borgatti 02 Jul '09

02 Jul '09

Hi, If you create a file simple.rb and put the following line inside: puts ("a@0ƒz" =~ /\x40/).inspect and then run with: macruby simple.rb I have the following: $ macruby simple.rb simple.rb:1:in `<main>': regexp preprocess failed: too short escaped multibyte character (ArgumentError) while it runs fine on ruby MRI (prints 1). The problem seems to be the use of hex/octals in the regexp but only when the string contains unicode chars. If you remove the "ƒ" everything goes as expected. Should I file a bug for this? Let me know, Thanks Renzo

Macruby 10x slower than built-in Ruby for my script
by zhida cheng 01 Jul '09

01 Jul '09

Hi all, I'm using ruby for some simple scripts for data processing, and I'm interested in Macruby since it's a mac friendly framework and very snappy too. But in this very simple (I think) script, Macruby is 10x slower than built-in Ruby in OSX 10.5.7 It's for reading atom positions, calculating distances, make a summary and find out nearest atoms. You can get the codes here: http://gist.github.com/138760 ------------------------------------------------------------------------------------------------------------------ require 'scanf' arr=IO.readlines(ARGV[0]) pos_data = arr[4..-1] pos = pos_data.collect{|a| a.scanf('%d %d %f %f %f')[2..4]} dist_matrix = pos.collect { |i| pos.collect{|j| (((i[0]-j[0])**2+(i[1]- j[1])**2+(i[2]-j[2])**2)**0.5*0.529*100).round/100.0}} dist_uniq = dist_matrix.inject([]) { |sum,i| sum|i } - [0.0] dist_min = dist_uniq.min dist_dup = dist_matrix.inject([]) { |sum,i| sum+i } dist_sum = dist_dup.inject(Hash.new(0)) { |h,i| h[i] += 1; h} dist_sum_sort = dist_sum.sort.find_all {|i| i[0]<3.0} dist_sum_sort.each { |i| puts "%.2f %d" %i } dist_matrix.each_with_index{|item,i| a=item.index(dist_min) if a then puts "%.2f: %d and %d"%[dist_min, a, i] end } ------------------------------------------------------------------------------------------------------------------ $time macruby dist.rb 309.xv real 0m17.084s user 0m26.893s sys 0m1.330s $time ruby dist.rb 309.xv real 0m1.052s user 0m0.981s sys 0m0.069s $time macruby-exp dist.rb 309.xv real 0m9.934s user 0m17.090s sys 0m0.643s ----------------------------------------------------------------------------------------------------------------------- the 309.xv file is too lengthy for email so you can download from the link. I also tested on several Macs and It's always the same. Any ideas? I admit the codes is not well optimized, but I don't think macruby should be so slow. Even 309**2 is not a too big number for current machines. Thanks, Sincerely Cheng

need help to get the Apple Remote Wrapper working with MacRuby
by Matt Aimonetti 01 Jul '09

01 Jul '09

Hi Guys, I wanted to port RubyCocoa old Apple Remote example to MacRuby but I encountered some issues. It looks like I'm now stuck and need some help :( Here is the code: http://github.com/mattetti/apple-remote-wrapper/tree/master I took Martin's source code, updated it to objective-c 2, enabled the GC, made sure the demos were still working. Created a new framework target and added bridgesupport. FYI to generate the BridgeSupport file, do the following: $ mkdir -p ~/src/RemoteControlWrapper_R962/build/Release/AppleRemote.framework/Resources/BrideSupport/ $ gen_bridge_metadata -f ~/src/RemoteControlWrapper_R962/build/Release/AppleRemote.framework/ -o ~/src/RemoteControlWrapper_R962/build/Release/AppleRemote.framework/Resources/BrideSupport/AppleRemote.bridgesupport bs generated file: http://gist.github.com/137201 I then created a new macruby xcode project, loaded the framework, created a new controller and binded it using IB. Here is my controller: class Controller def awakeFromNib remoteControl = AppleRemote.alloc.initWithDelegate(self) remoteControl.startListening(self) p remoteControl.isListeningToRemote end # - (void) sendRemoteButtonEvent: (RemoteControlEventIdentifier) event pressedDown: (BOOL) pressedDown remoteControl: (RemoteControl*) remoteControl; def sendRemoteButtonEvent(event, pressedDown:pressed, remoteControl:remote) p 'button pressed' end end When the app loads, the AppleRemote instance is listening properly but when I click on the button my code crashes and here is the bt: http://gist.github.com/raw/137199/948a2bbe0a45d942977563350a3bf15c27b4ee55/… #0 0x00007fff82bc3490 in realizeClass () #1 0x00007fff82bc354e in realizeClass () #2 0x00007fff82bc354e in realizeClass () #3 0x00007fff82bc3d17 in _objc_fixupMessageRef () #4 0x00007fff82bc5c7f in objc_msgSend_fixup () #5 0x00007fff83bfe587 in __CFMachPortPerform () #6 0x00007fff83c202cc in CFRunLoopRunSpecific () #7 0x00007fff84582bce in RunCurrentEventLoopInMode () #8 0x00007fff84582a04 in ReceiveNextEventCommon () #9 0x00007fff845828af in BlockUntilNextEventMatchingListInMode () #10 0x00007fff8314e420 in _DPSNextEvent () #11 0x00007fff8314dd61 in -[NSApplication nextEventMatchingMask:untilDate:inMode:dequeue:] () #12 0x00007fff83147af4 in -[NSApplication run] () #13 0x00007fff831148ac in NSApplicationMain () #14 0x0000000102880940 in ?? () Any help would be much appreciated. Thanks, - Matt
