#144: require of hotcocoa fails on case sensitive file system -------------------------------+-------------------------------------------- Reporter: rune(a)snuskete.com | Owner: lsansonetti(a)apple.com Type: defect | Status: new Priority: trivial | Milestone: Component: MacRuby | Keywords: hotcocoa -------------------------------+-------------------------------------------- When hotcocoa includes the Cocoa library it uses the wrong case, resulting on the following stack trace when you are using a case sensitive file system: {{{ >> require 'hotcocoa' RuntimeError: framework `cocoa' not found from /Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/1.9.0/hotcocoa.rb:1:in `framework' from /Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/1.9.0/hotcocoa.rb:1:in `<top (required)>' from (irb):2:in `require' from (irb):2 from /usr/local/bin/macirb:12:in `<main>' }}} The fix is easy; change the first line of hotcocoa.rb to: framework 'Cocoa' -- Ticket URL: <http://www.macruby.org/trac/ticket/144> MacRuby <http://macruby.org/>

Re: [MacRuby-devel] hotcocoa not loading cocoa framework
by Robert Schaaf 31 Jan '09

Hello all (again), I may have found the root of the problem. If so, I need a fix. Laurent's hint, 'NSBundle.bundleWithPath('/System/Library/Frameworks/ Cocoa.framework').load' succeeds,. Tim Rand's pointing out the $: variable was a big help, and here's the result: >> $:.each {|sp| puts sp + "\n"} /Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/gems/ 1.9.0/gems/rb-appscript-0.5.1/lib /Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/gems/ 1.9.0/gems/yahoofinance-1.2.2/lib /Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/ site_ruby/1.9.0 /Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/ site_ruby/1.9.0/universal-darwin9.0 /Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/ site_ruby /Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/ vendor_ruby/1.9.0 /Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/ vendor_ruby/1.9.0/universal-darwin9.0 /Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/ vendor_ruby /Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/1.9.0 /Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/1.9.0/ universal-darwin9.0 It looks like /System/Library/Frameworks/ is not in my search path. The questions are why not? how do I remedy this? and will doing so make it work? Even more thanks, Bob Schaaf

hotcocoa - can't find executable...how to find it
by Robert Schaaf 30 Jan '09

30 Jan '09

Thanks Tim, this is helpful, but the problem is that once hotcocoa.rb is found, is fails on line 1, framework 'cocoa', thus: > RuntimeError: framework at path `cocoa' cannot be loaded: Error > Domain=NSCocoaErrorDomain Code=4 UserInfo=0x136c620 "The bundle > “cocoa” could not be loaded because its executable could not be > located." > from /Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ > ruby/1.9.0/hotcocoa.rb:1:in `framework' > Is this because the cocoa framework can't be found, or that it might be corrupted, or what? Here are the paths that your suggestion returns, with added newlines for clarity (and a several non-working gems!) ["/Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/gems/ 1.9.0/gems/rb-appscript-0.5.1/lib", "/Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/ gems/1.9.0/gems/yahoofinance-1.2.2/lib", "/Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/ site_ruby/1.9.0", "/Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/ site_ruby/1.9.0/universal-darwin9.0", "/Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/ site_ruby", "/Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/ vendor_ruby/1.9.0", "/Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/ vendor_ruby/1.9.0/universal-darwin9.0", "/Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/ vendor_ruby", "/Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/ 1.9.0", "/Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/ 1.9.0/universal-darwin9.0", "."] Could it have been a macgem install gone bad that clobbered something? What does a normal macruby installation look like?

hotcocoa - can't find executable...how to find it
by Tim Rand 30 Jan '09

30 Jan '09

>> $:.each{|path| puts path + "/" + "hotcocoa.rb" if File.exists?(path + "/" + "hotcocoa.rb")} /Library/Frameworks/MacRuby.framework/Versions/0.4/usr/lib/ruby/1.9.0/hotcocoa.rb $: is a ruby environmental variable for an array of all the paths that ruby looks at to require a file. Another useful one to know is $", which holds the names of all currently loaded external files. I would imagine that somehow the path setting has been altered or you accidentally moved hotcocoa to a location not included in the $: set. I am frustrated that macgem is not functioning too. There are a lot of possible reasons for it, but the most likely seems to be that many of the gems for older versions of ruby need to be updated to work with 1.9, the version that macruby is based on. Alternatively, failure of any given gem to load could be due to macruby being under development and yet incomplete. For me getting certain gems like sqlite3 to funciton with macruby is a necessity. Perhaps wonderful Laraunt or someone else could share some of his/her wisdom on this issue of why many gems don't work, and if there is a plan for how to fix it. Otherwise, I am going to keep plugging away at it in my spare time--maybe around 2050 or so I will solve it. But I will solve it eventually, because I love the idea of macruby and I love my old gem library and I can't live without either. Tim

Thanks for the fast turnaround. I'm running on 10.5.6 on 1 MacBook Pro 17", Core 2 Duo at 2.33 GHz. As far as running the commands manually, here are the results. Last login: Thu Jan 29 19:25:20 on ttys001 travelers-macbook-pro-17:~ traveler$ macruby -e "NSBundle.bundleWithPath('/System/Library/Frameworks/ Cocoa.framework').load; p :ok" :ok travelers-macbook-pro-17:~ traveler$ macruby -e "framework 'Cocoa'" -e:1:in `framework': framework at path `Cocoa' cannot be loaded: Error Domain=NSCocoaErrorDomain Code=4 UserInfo=0x10966f0 "The bundle “Cocoa” could not be loaded because its executable could not be located." (RuntimeError) from -e:1:in `<main>' travelers-macbook-pro-17:~ traveler$ I hope you can figure this out! BTW, is there a way to change my setting from digest to individual messages?

hotcocoa - can't find executable
by Robert Schaaf 29 Jan '09

29 Jan '09

Hello everybody, I'm new to these parts, so maybe this has already been asked and answered. When I first installed version 3, HotCocoa worked fine, Now, somehow, after a couple of months of not looking at it, this happens: travelers-macbook-pro-17:~ traveler$ macirb >> require 'hotcocoa' RuntimeError: framework at path `Cocoa' cannot be loaded: Error Domain=NSCocoaErrorDomain Code=4 UserInfo=0x16a1480 "The bundle “Cocoa” could not be loaded because its executable could not be located." from /Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/ 1.9.0/hotcocoa.rb:1:in `framework' from /Library/Frameworks/MacRuby.framework/Versions/0.3/usr/lib/ruby/ 1.9.0/hotcocoa.rb:1:in `<top (required)>' from (irb):1:in `require' from (irb):1 from /usr/local/bin/macirb:12:in `<main>' >> Does anyone know why? Is it a path probelm? Where exactly is this executable supposed to be? Please help, and them I can get on to the heartbreak of macgem. Thanks., Bob Schaaf

Interesting "conversion candidate" for MacRuby?
by Jordan K. Hubbard 29 Jan '09

Someone just pointed me at this bit of sample code today, in an unrelated discussion, and it occurred to me that it might make a nice project for someone seeking to learn MacRuby by starting with a more simple "translation project": http://developer.apple.com/samplecode/GeekGameBoard/index.html The solitaire example is even playable. :) - Jordan

Re: [MacRuby-devel] Distributing apps with MacRuby.framework

The way I do it is to have a copy frameworks build phase, and a "Run Script" build phase that runs last with the following script (rather, that should all be one line): install_name_tool -change /Library/Frameworks/MacRuby.framework/Versions/0.4/usr/lib/libmacruby.dylib @executable_path/../Frameworks/MacRuby.framework/Versions/0.4/usr/lib/libmacruby.dylib "$TARGET_BUILD_DIR/$EXECUTABLE_PATH" On Jan 22, 2009, at 7:31 , Dr Nic Williams wrote: > I recently shared a MacRuby app with a friend, with MacRuby.framework > included in the .app via a Copy Files target; but the app died on his > machine complaining that /Library/Frameworks/MacRuby.framework wasn't > available.

PBI - translate TextEdit to MacRuby
by Rich Morin 29 Jan '09

29 Jan '09

A friend of mine asked: > What word processor do you use on the Mac? I'd like to > find an open-source, lightweight rich text editor (not > OpenOffice... too big). Any suggestions? His question made me think of a nifty project. TextEdit is one of the canonical example programs in the Mac OS X Developer Tools. It's not all that big, really: $ cd /Developer/Examples/AppKit/TextEdit/ $ wc -l *.h 5 Controller.h 124 Document.h 26 DocumentController.h 11 DocumentPropertiesPanelController.h 23 DocumentWindowController.h 49 EncodingManager.h 11 LinePanelController.h 23 MultiplePageView.h 100 Preferences.h 11 PrintPanelAccessoryController.h 14 ScalingScrollView.h 16 TextEditErrors.h 413 total $ wc -l *.m 140 Controller.m 1110 Document.m 269 DocumentController.m 133 DocumentPropertiesPanelController.m 702 DocumentWindowController.m 5 Edit_main.m 344 EncodingManager.m 162 LinePanelController.m 209 MultiplePageView.m 418 Preferences.m 87 PrintPanelAccessoryController.m 201 ScalingScrollView.m 3780 total The usual claim is that Ruby is several times smaller than C, C++, etc. Let's assume that a factor of four is typical. This would let TextEdit be recapitulated in 1000 LOC of Ruby. It would run about as fast (most of the work is done in the Apple frameworks) and it would be easily extensible in Ruby. In fact, it could use user- or site-specific "libraries" stored in initialization files. Does anyone else find this notion interesting? -r -- http://www.cfcl.com/rdm Rich Morin http://www.cfcl.com/rdm/resume rdm(a)cfcl.com http://www.cfcl.com/rdm/weblog +1 650-873-7841 Technical editing and writing, programming, and web development
