MacRuby PrefPane
by Michael Jackson 12 Jun '10

12 Jun '10

Hi all, I've been trying to set up a preference pane in MacRuby this afternoon, but I'm not sure the right way to go about it. In Cocoa it's easy because there's a "preference pane bundle" project type in the new project dialog box in Xcode. So what I did was I created a new preference pane project in Cocoa and a new MacRuby app and then tried to make the MacRuby app look as much like the Cocoa prefpane as I could (by editing the Info.plist file, adding the PreferencePanes.framework to the project, etc.) The one problem I have at this point (there are probably more than one, but...) is that I don't have a prefpane bundle under my targets. I just have the App, Unit Tests, Compile, and Embed targets. I don't know what to do at this point. I have a feeling that there should be an easier way to do all of this, but I don't know how. Any suggestions would be greatly appreciated. Perhaps someone has a MacRuby prefpane bundle they're willing to share? Thanks, Michael -- Michael Jackson http://mjijackson.com @mjijackson

[MacRuby] #424: performance regression from ruby 1.8 and 1.9

#424: performance regression from ruby 1.8 and 1.9 -------------------------------------+-------------------------------------- Reporter: jordan.breeding@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: -------------------------------------+-------------------------------------- I have some code that previously ran incorrectly on MacRuby 0.4, and until recently crashed MacRuby trunk. Now that it works I would like to report that the performance of it is not as fast as 1.8 or 1.9. I know that MacRuby working is a primary consideration and speed only comes after that, but as people start looking at speed more and more I wanted to get this on the radar. This also supersedes #348 which was a smaller also based on this code, but was a reduced file since the main code would not run. Performance of Ruby 1.8, Ruby 1.9, and MacRuby compared using a faster and a slower version of the same basic algorithm: {{{ 35 jordan@thetourist ~/priority_queue_bug > for LOOP in ruby ruby1.9 macruby; do for LOOP2 in ./search.pqueue ./search_slow.pqueue; do eval time "${LOOP}" "${LOOP2}" -m -c a-star input_files/input13_7.txt >/dev/null; done; done ruby ./search.pqueue -m -c a-star input_files/input13_7.txt 4.51s user 0.10s system 98% cpu 4.657 total ruby ./search_slow.pqueue -m -c a-star input_files/input13_7.txt 9.84s user 0.15s system 98% cpu 10.087 total ruby1.9 ./search.pqueue -m -c a-star input_files/input13_7.txt 2.74s user 0.08s system 98% cpu 2.851 total ruby1.9 ./search_slow.pqueue -m -c a-star input_files/input13_7.txt 5.80s user 0.11s system 99% cpu 5.960 total macruby ./search.pqueue -m -c a-star input_files/input13_7.txt 14.30s user 0.69s system 171% cpu 8.722 total macruby ./search_slow.pqueue -m -c a-star input_files/input13_7.txt 27.30s user 0.88s system 150% cpu 18.745 total }}} performance of various versions of the script specific to MacRuby: {{{ 36 jordan@thetourist ~/priority_queue_bug > for LOOP in *.cocoa; do eval time macruby "${LOOP}" -c -m a-star input_files/input13_7.txt >/dev/null; done macruby search.cocoa -c -m a-star input_files/input13_7.txt 14.38s user 0.79s system 161% cpu 9.392 total macruby search_group_add.cocoa -c -m a-star input_files/input13_7.txt 13.61s user 0.71s system 171% cpu 8.345 total macruby search_group_add_slow.cocoa -c -m a-star input_files/input13_7.txt 26.97s user 0.92s system 146% cpu 19.027 total macruby search_slow.cocoa -c -m a-star input_files/input13_7.txt 27.34s user 0.94s system 150% cpu 18.730 total }}} MacRuby information: {{{ 37 jordan@thetourist ~/priority_queue_bug > macruby -e 'p MACRUBY_VERSION' "0.5" 38 jordan@thetourist ~/priority_queue_bug > macruby -e 'p MACRUBY_REVISION' "git commit 19b2d7811662bf636cbcc2fe1ae99afef3243225" }}} -- Ticket URL: <http://www.macruby.org/trac/ticket/424> MacRuby <http://macruby.org/>

It's kind of a complicated setup, so I've created a minimal-ish project in github containing ObjC and MacRuby code to illustrate the problem. It's here: http://github.com/diffengr/macruby_forwarding_invocation_example That contains an XCode project and a rakefile. It has the ObjC classes Candy and CandyWrapper, and they both have the NSString* property flavor. CandyWrapper declares that property @dynamic, and forwards it to Candy. Here's the code that works in ObjC. Candy* rootBeerCandy = [[Candy alloc] init]; rootBeerCandy.flavor = @"Root Beer"; CandyWrapper* rootBeerWrapper = [[CandyWrapper alloc] initWithCandy:rootBeerCandy]; NSLog(@"Candy#flavor \"%@\", Wrapper#flavor \"%@\"", rootBeerCandy.flavor, rootBeerWrapper.flavor); If you load and run the xcode project in this directory, you'll get this output: NSLog[...] <CandyWrapper: 0x104fb0> forwarding flavor to <Candy: 0x103380> NSLog[...] Candy#flavor "Root Beer", Wrapper#flavor "Root Beer" Here's that same code instantiated in MacRuby, from candy_test.rb: rootBeerCandy = Candy.alloc.init rootBeerCandy.flavor = 'Root Beer' rootBeerWrapper = CandyWrapper.alloc.initWithCandy rootBeerCandy puts "Candy#flavor #{rootBeerCandy.flavor}, Wrapper#flavor #{rootBeerWrapper.flavor}" You can run this with "macrake test" in the project directory, and it will give (among other things): candy_test.rb:7:in `<main>': undefined method `flavor' for #<CandyWrapper:0x8000aa2a0> (NoMethodError) rake aborted! -- Ticket URL: <http://www.macruby.org/trac/ticket/330> MacRuby <http://macruby.org/>
