Re: [MacRuby-devel] Rspec Stopped Running Under Macruby

Christian, Reverting to Rspec 2.5 allowed rspec to run under macruby (so far.) However, it is extremely slow compared to running under system ruby. it takes 10+ seconds to run just an empty test and pegs out one of my cores to do so. Macruby should run faster than the system ruby 1.8.7 so I think I've still got a Macruby problem somewhere. Guess I need to do another post. Thanks, Shannon

CGRectZero
by Jason Voegele 22 May '11

22 May '11

Hi, I'm working on a new MacRuby application, and I'm using the updated HotCocoa from this fork: https://github.com/ferrous26/hotcocoa This version of HotCocoa contains several references to the CGRectZero constant, but this constant does not appear to be exposed in MacRuby (0.10). I did some poking around and found that, after performing a "framework 'Cocoa'" call, these other CGRect* constants are defined: CGRect CGRectMaxXEdge CGRectMaxYEdge CGRectMinXEdge CGRectMinYEdge However, CGRectZero is not defined. Is there any other way to access this constant from MacRuby? Is there any reason it is not defined? Thanks! -- Jason Voegele "It is better to have tried and failed than to have failed to try, but the result's the same." - Mike Dennison

Does MacRuby Play Well with RVM?
by Shannon Love 22 May '11

22 May '11

Last week I attempted to install RVM on my system so I could use various versions of Ruby including Macruby. I encountered problems including a reinstall of RVM that had incorrect permissions. However, it is quite possible that all the errors were the result of my naviety about the ruby environment so I'm willing to give it another go. Has anyone else used RVM with Macruby and does it work well? Can I safely run multiple versions of Macruby? Will it alter or contaminate the regular installed version? Any advice would be appreciated. Thanks, Shannon

String#sub/gsub and text encodings
by Yasu Imao 21 May '11

21 May '11

Hi, I just wrote a simple script for text processing and encountered a problem with String#sub/gsub. Original text: UTF-8 encoded ASCII character only text Replacing text: UTF-8 encoded text with ASCII and non-ASCII characters (including Japanese characters) The resulting text: all the non-ASCII characters were garbage. When I split the original text at the strings to be replaced and inserted the replacing text at these places, the resulting string object was fine; all the characters were kept as they should be in UTF-8 encoding. I checked the tickets, but couldn't find something like this. Is this a known issue? Best, Yasu

I can attend the meeting, discuss the project and answer questions though (like a BoF, which I thought was the plan here). I wouldn't use the word "formal" to describe my talk, but Pivotal is welcome to record it and put it online. :) I was asked to speak at this event by Rich Morin, after giving a short presentation on MacRuby to the SFRuby group last month. Here are the slides for the talk I delivered at SFRuby: http://www.scribd.com/doc/52652887/GUI-Programming-with-MacRuby In that talk, I tried to make the case that MacRuby is the best choice for Rubyists who want to do native, GUI development. I assume the audience for this event will be coming in with more of an Cocoa/Objective-C background, so I will probably rework the talk to focus on why they might want to consider learning MacRuby. Does that seem about right?

Clean Install of Macruby?
by Shannon Love 20 May '11

20 May '11

Is there an a formal or approved way of performing a clean install of Macruby including gems? I fear that I may have mangled my install with my naive use of RVM and I wanted to try and start fresh. I've already used pkgutil to uninstall all the files associated with the Macruby package and installed again but I wonder if one of the gems might have left an executable in a /bin somewhere (or something else somewhere else.) I'm probably paranoid but it would be nice to start over with a known clean slate (short of system reinstall) if possible. S

Re: [MacRuby-devel] Rspec Stopped Running Under Macruby
by Shannon Love 20 May '11

20 May '11

I it appears I spoke to soon in my previous mail. Reverting to Rspec 2.5 got me to where I could run basic test but now I get sig fault when I try to use an expectation (should statement.) It even happens with example code I copied from the rspec 2.5 docs. Just for grins, I ran rspec own spec for the expectations and as I expected, they crashed as well. I think I'll have to abandon rspec and macruby for now as I have run out of time to fiddle with it. Shannon

Rspec Stopped Running Under Macruby
by Shannon Love 20 May '11

20 May '11

I had previously had Rspec running under Macruby before I tried to use RVM to manage my ruby installs. Something went awry with RVM and I had to uninstall. After that Rspec stopped working under Macruby. I I found that my RVM had installed Macruby 0.11 dev in or over my 0.10 install and that remained even after I had removed RVM so I used pkgutil to uninstall all Macruby, then I reinstalled the system ruby package and then reinstall Macruby 0.10 The system ruby 1.8.7 runs rspec installed with its gem command just fine. However, if I uninstall the system rspec and install with macgem, I get the following error trying to either execute a file with rspec calls or running rspec from the command line with or without any options or files. <code> /Library/Frameworks/MacRuby.framework/Versions/0.10/usr/lib/ruby/Gems/1.9.2/gems/rspec-core-2.6.0/lib/rspec/core/world.rb:14:in `empty_without_conditional_filters?': undefined method `empty?' for #<Enumerator:0x2002a76c0> (NoMethodError) from /Library/Frameworks/MacRuby.framework/Versions/0.10/usr/lib/ruby/Gems/1.9.2/gems/rspec-core-2.6.0/lib/rspec/core/world.rb:131:in `announce_exclusion_filter:' from /Library/Frameworks/MacRuby.framework/Versions/0.10/usr/lib/ruby/Gems/1.9.2/gems/rspec-core-2.6.0/lib/rspec/core/world.rb:103:in `announce_filters' from /Library/Frameworks/MacRuby.framework/Versions/0.10/usr/lib/ruby/Gems/1.9.2/gems/rspec-core-2.6.0/lib/rspec/core/command_line.rb:19:in `run:' from /Library/Frameworks/MacRuby.framework/Versions/0.10/usr/lib/ruby/Gems/1.9.2/gems/rspec-core-2.6.0/lib/rspec/core/runner.rb:80:in `run_in_process:' from /Library/Frameworks/MacRuby.framework/Versions/0.10/usr/lib/ruby/Gems/1.9.2/gems/rspec-core-2.6.0/lib/rspec/core/runner.rb:69:in `run:' from /Library/Frameworks/MacRuby.framework/Versions/0.10/usr/lib/ruby/Gems/1.9.2/gems/rspec-core-2.6.0/lib/rspec/core/runner.rb:11:in `block' localhost:SetUpRspec developer$ which rspec </code> The the actual error line is here and it appears to be part of the way that Rspec processes command line arguments: <code> module RSpec module Core class World module Describable PROC_HEX_NUMBER = /0x[0-9a-f]+@/ PROJECT_DIR = File.expand_path('.') def description reject { |k, v| RSpec::Core::Configuration::CONDITIONAL_FILTERS[k] == v }.inspect.gsub(PROC_HEX_NUMBER, '').gsub(PROJECT_DIR, '.').gsub(' (lambda)','') end def empty_without_conditional_filters? 14 => reject { |k, v| RSpec::Core::Configuration::CONDITIONAL_FILTERS[k] == v }.empty? end def reject super rescue {} end def empty? super rescue false end end </code> I'm a ruby noob but I think it's trying to process a block returned by `super rescue` and it expects a collection but receives an enumerator instead. Why that is, I don't know. Repeated macgem installs of the rspec gem do nothing to alter the issue. I can't find any other references to similar problems. I assume that in my naivety with RVM and ruby in general, I wrecked something somewhere in the system that breaks rspec or macruby but I don't know how to fix it. Thanks, TechZen

Documentation: appel_ref marker strings for Ruby?
by Andrew O'Brien 19 May '11

19 May '11

Hi, I've been looking into writing a YARD plugin that would output documentation in the Apple docset format. I ran into a bit of a problem when I was trying to setup a Tokens.xml (for API lookup) and found that there were no marker strings for Ruby. According to the HeaderDoc User guide, there's C, Obj-C, Java, JavaScript, C++, PHP, Pascal, Perl, and Shell. It looks like docsetutil actually checks against this list because supplying "rb" as the lang type appeared to blow it up. What are the chances we could get some blessed symbol types for Ruby? Thanks, Andrew

Asking Apple for Syntax Highlighting
by Alec Sloman 19 May '11

19 May '11

A follow up to my earlier thread re: syntax highlighting in XCode 4. I just submitted a feature request with Apple, but subsequently noticed that Matt Aimoneti had posted something similar in the Apple Dev. Forums and he was advised to do the same thing (submit via their bug reporter), by Apple, two months ago. I am curious if anything ever came of that? I don't want to annoy them with duplicated requests :P That said, I was able to find the various pbfilespec files and am looking at them now... Regards, Alec -- alecsloman.tumblr.com
