rb_obj_class not called for 'puts Array.new.class'
by Steve Canfield 26 Apr '11

26 Apr '11

Although reading through the code I would think the method "class" would be bound to the C function "rb_obj_class", that clearly isn't the case. Can someone explain (briefly) how the mappings in object.c Init_Object() are used at runtime? This is all in relation to understanding the code around http://www.macruby.org/trac/ticket/1141. Thanks. -Steve

pkg doesn't install from GUI but does from terminal
by Rob Ista 23 Apr '11

23 Apr '11

hi all, does anyone have experience with archiving macruby apps? I can't get the pkg file to install from the desktop but running installer from a terminal just runs fine .. i get a "xxxxx can't be installed on this computer" when i double-click on the pkg ... the imac is a core duo 2 .. osx 10.6.7 .. i compiled and deployed the app with LLVM 2.0, x86_64, SDK 10.6 ... the deployed app runs fine on any of my machines but just the pkg file doesn't allow to install the app properly .. it kinda blocks my upload to the app store now :) .. any hints appreciated .. cheers, Rob

Re: [MacRuby-devel] How do I get gems into XCode/MacRuby environment?
by Paul Davis 19 Apr '11

19 Apr '11

Good suggestion. macgem install hpricot # installs the gem (apparently) macgem list --local # now shows rake and hpricot as the only two local gems... After experimentation this appears to be because these are the only two loaded under rvm for ruby 1.9.2. "macgem list --local" is just picking up whatever gems are in the currently selected rvm environment, but not all of these are showing up in XCode. Code snippet in rb_main.rb: > ['rubygems', 'pp', 'rake'].each {|gem| > puts "Loading '#{gem}'... #{require gem}" #=> true > } > system ('macgem list --local') ==> > Loading 'rubygems'... true > Loading 'pp'... true > Loading 'rake'... true > > *** LOCAL GEMS *** > > > applicationDidFinishLaunching More testing later.

Hash Table
by Petr Kaleta 18 Apr '11

18 Apr '11

Hi I'm a little bit confused about basic ruby classes implementation. Ruby Hash is internally implemented as NSDictionary/NSMutableDictionary? So for example if I need to implement hash table, I can use ruby Hash? So the performance will be exactly same compared to NSDictionary? - Petr

NSString.to_data
by Robert Rice 18 Apr '11

18 Apr '11

Using the Scripting Bridge to process e_mails, the bridge return NSString rather than String class when reading the message content. This works fine except that the .to_data method is undefined for NSString. I am able to use dataUsingEncoding as in the following: content = message.content.get # Returns NSString rather than String nsdata = content.dataUsingEncoding( NSASCIIStringEncoding ) nsdata.writeToURL( @url, atomically:true ) But for consistency, you may want to add the .to_data method to the NSString class. Thanks, Bob Rice

MacRuby / Hotcocoa / Macrake issue
by Nick Brandaleone 18 Apr '11

18 Apr '11

Hello, I am new to MacRuby, and I am loving it! :-) I have done some RubyCocoa programming in the past, but I am now playing around with the MacRuby frameworks. I am having an issue with macruby/hotcocoa and macrake. It looks like it is a loader/linker issue with the wrong architecture. I am running x_64, and I believe the loader is referencing a 32-bit build. I understand how to alter this using Xcode, but I am not sure how to correct this for the MacRuby/hotcocoa/macrake framework. Or is it something else entirely?! =========================================================== [macpro:~/src/macruby/my_first_app] macrake run (in /Users/nbrand/src/macruby/my_first_app) ld: warning: ignoring file /Library/Frameworks//MacRuby.framework/MacRuby, file was built for unsupported file format which is not the architecture being linked (i386) Undefined symbols for architecture i386: "_macruby_main", referenced from: _main in ccTmkyxO.o ld: symbol(s) not found for architecture i386 collect2: ld returned 1 exit status lipo: can't open input file: /var/folders/bx/bxsDMQkhFGCnAlLx4sEiEE+++TM/-Tmp-//ccDFJISw.out (No such file or directory) /bin/sh: ./My First App.app/Contents/MacOS/MyFirstApp: No such file or directory =========================================================== Nick

macruby_deploy --embed bug
by Nathaniel Talbott 18 Apr '11

18 Apr '11

I'm now on master in order to get the BridgeSupport fix, but my archived applications are erroring now due to a LOAD_PATH issue. Basically, the embedded framework is in: Elephant.app/Contents/Frameworks/MacRuby.framework/Versions/Current But the LOAD_PATH for the app is now: Elephant.app/Contents/Frameworks/MacRuby.framework/Versions/0.11 It manifests as not being able to require any files in the stdlib. Tonight I'll be able to submit a reproduction of the issue (have to run out now) but in the meantime, any ideas as to what the cause might be? Thanks, -- Nathaniel Talbott <:((><

BridgeSupport crash
by Nathaniel Talbott 17 Apr '11

17 Apr '11

I have a MacRuby app that's working great on my local box, but when I put it on another box it crashes hard. Here's the relevant thread crash info: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x00000000ffffffff Crashed Thread: 0 Dispatch queue: com.apple.main-thread Thread 0 Crashed: Dispatch queue: com.apple.main-thread 0 libmacruby.1.9.2.dylib 0x000000010010c4b1 rb_vm_resolve_const_value + 1537 1 libmacruby.1.9.2.dylib 0x00000001000f52f6 rb_objc_load_loaded_frameworks_bridgesupport + 374 2 libmacruby.1.9.2.dylib 0x0000000100157f0a macruby_main + 362 3 com.terralien.Elephant 0x000000010000142f 0x100000000 + 5167 4 com.terralien.Elephant 0x00000001000013f4 0x100000000 + 5108 The app runs fine on my own box, and the only difference I can figure between them is that I've installed BridgeSupport preview3, but the box it's crashing on hasn't. I'm doing a macruby_deploy --bs and have verified that the BridgeSupport files are being copied into the right spot in the .app file. Any ideas what might be wrong and/or how I can debug further? -- Nathaniel Talbott <:((><

Re: [MacRuby-devel] WWDC ?

It isn't all that easy to find out which evenings are hammered for WWDC. It appears that: Mon 6 - Tue 7 - might conflict w/ Design Awards Wed 8 Thu 9 - bad; conflicts with WWDC Bash Fri 10 - bad; many folks are leaving I realize that lots of folks are loathe to go out on Monday night (6/6), but that seems like a possibility. Are there any objections or counter-proposals? -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 Software system design, development, and documentation
