Core Dump When Importing 3rd Party gems
by Templeton Jason 14 Nov '12

14 Nov '12

I've been having some problems importing 3rd party gems. Basically, this is what happens #!/usr/local/bin/macruby framework 'Foundation' framework 'ScriptingBridge' framework 'cocoa' puts "Hola" require "rubygems" puts "Imported rubygems" require "mechanize" puts "Imported mechanize..." I will get a Segmentation Fault when I import mechanize, this also happens if I replace the import of mechanize with 'nokogiri'. I can import sqlite3, but I just can't refer to SQLite3::Database.new, otherwise, I get another Segmentation Fault In other words, I will see from the above code: Hola Imported rubygems Segmentation fault This is my setup [ jtempleton macruby_client(master) 01:11 ] macruby -v MacRuby 0.12 (ruby 1.9.2) [universal-darwin10.0, x86_64] Mac Version 10.6.8, 2Ghz Core i7, 8GB RAM $ macgem list ** LOCAL GEMS ** ----- mechanize (2.5.1) nokogiri (1.5.2, 1.5.0, 1.4.3.1) sqlite3 (1.3.5) sqlite3-ruby (1.3.3) ------ I was also having the same thing occur on macRuby 0.11 Any suggestions would be greatly appreciated. Thank you!!! Jason

Using scripting bridge to create new objects within a Cocoa App.
by Kevin Poorman 28 Oct '12

28 Oct '12

Morning, I've been trying to use MacRuby to drive an integration between a popular webservice and the stock Reminders.app. I'm attempting this through the scripting bridge and am running into difficulty getting the scripting bridge Create new objects within reminders.app, or notes.app, or any other app i've tried. Examplar code: n = SBApplication.applicationWithBundleIdentifier("com.apple.notes") new_note = NotesApplication::NotesNote.new #NoMethodError: undefined method `==' for "#<SBProxyByClass:0x403a45ea0>":String Ok, so perhaps I need to give it some options. lets try name: new_note = NotesApplication::NotesNote.new name = "foo" ArgumentError: wrong number of arguments (1 for 0) (irb):138:in `<main>' harumph. Ok well lets fire up the dictionary - it says the method is "make" n.methods(true,true).grep /make/i # [] hmm. ok NotesApplication.methods(true,true).grep /make/i # [] I can't find the make method on any object and new is throwing an odd error that I can't seem to inspect. Help?

xcode question
by david kramf 25 Oct '12

25 Oct '12

….I am new to mac , macruby , ruby etc I have built an application using XCODE and when I click RUN on XCODE the application runs and does what I intended here to do. But … I don't find the way to run it OUTSIDE of XCODE , like any other app I have on my mac. When I look at the directory of my app , it does not have the structure of my regular applications located in /Applications folder. I tried to find an answer in MAC Developer library but got lost (??) so I apologize if this is too simple a question Many Thanks, David Kramf

Quartz 2D Graphics problem
by Robert Carl Rice 25 Oct '12

25 Oct '12

Hi, I went back to working on an old project that uses core graphics and I'm having problems getting it to run again. The following code gives me an error with the graphics context: def drawRect( rect ) return unless @controller begin @context = NSGraphicsContext.currentContext.graphicsPort # Scale 15 min intervals to chart area @xscale = bounds.size.width / 25.0 height = bounds.size.height @yscale = height / 2.0 CGContextScaleCTM( @context, @xscale, @yscale ) CGContextTranslateCTM( @context, 0.5, 0.5 ) # Indent from bounds # restore text size CGContextSetTextMatrix( @context, CGAffineTransformMakeScale( 1 / @xscale, 1 / @yscale )) show_index( height ) rescue => e ErrorLog.instance.rescue_error( e ) end end unrecognized runtime type `{CGContext=}' /Users/robertrice/Library/Developer/Xcode/DerivedData/MacDriverLog-ebberjlfoqoqdzenjgqkdbkehuoj/Build/Products/Debug/MacDriverLog.app/Contents/Main_Window.bundle/Contents/Resources/RemarksIndexView.rb:55:in `drawRect' /Users/robertrice/Library/Developer/Xcode/DerivedData/MacDriverLog-ebberjlfoqoqdzenjgqkdbkehuoj/Build/Products/Debug/MacDriverLog.app/Contents/Resources/rb_main.rb:69:in `<main>' line 55 is the first line: @context = NSGraphicsContext.currentContext.graphicsPort Has anything changed with regard to Quartz 2D drawing?

Basic delayed email method
by Cliff Rosson 24 Oct '12

24 Oct '12

Hi Everyone, I am fairly new to macruby and am having trouble finding some basic documentation to help me out. I would like to write a simple app that sends a delayed email based on Time from mac mail. I am thinking of something like this, time = Time.now + 3600 while true case time when Time.now #Send email end end Being able to respond to certain emails or send an email from a draft would be a huge benefit. Can anyone point me in the write direction to accomplish this? I am decently proficient in ruby but don't know where to start with MacRuby. Thanks everyone

Hi, I recently added some NSSound alerts to one of my project. It works but it generates a "GC operation on unregistered thread" warning when I play the sound. Is there a way to avoid this warning? Thanks, Bob Rice

Monitoring file system changes
by stephen horne 18 Oct '12

18 Oct '12

I've cobbled together a class that wraps FSEventStreamCreate so that I can monitor a settings.json file and update my application upon its change - à la Sublime Text 2. I refactored the code I found on the subject in Matt Aimonetti's book. So far, it seems to be doing what I expect, but it would ease my mind a bit if someone who know something of the subject could tell me if I'm setting myself up for problems, as I don't really understand what's happening in the background. Here's an example of it in use: framework 'cocoa' class FolderWatch def initialize(paths, callback, object) @callback = callback @paths = [paths].flatten callback = Proc.new do |stream, client_callback_info, number_of_events, paths_pointer, event_flags, event_ids| paths_pointer.cast!("*") # cast as a string pointer stuff = { stream:stream, client_callback_info:client_callback_info, number_of_events:number_of_events, paths_pointer:paths_pointer, event_flags:event_flags, event_ids:event_ids } object.send(@callback, stuff) end @stream = FSEventStreamCreate(KCFAllocatorDefault, callback, nil, @paths, KFSEventStreamEventIdSinceNow, 0.0, 0) FSEventStreamScheduleWithRunLoop(@stream, CFRunLoopGetCurrent(), KCFRunLoopDefaultMode) end def start FSEventStreamStart(@stream) end def stop FSEventStreamStop(@stream) end end class Klass def callback(hash) puts hash[:paths_pointer][0] end end callback_object = Klass.new f = FolderWatch.new("/Users/fatboy/Desktop", :callback, callback_object) f.start -- Stephen Horne

Re: [MacRuby-devel] MacRuby-devel Digest, Vol 56, Issue 5

On 17 oct. 2012, at 23:03, <macruby-devel-request(a)lists.macosforge.org<mailto:macruby-devel-request@lists.macosforge.org>> wrote: I'm afraid setting the variable again in Xcode is not an option. I was hoping to pick up $CATALINA_HOME to find out where a user had installed tomcat. So where and when is that environment variable set? If you can instruct your user to set it in the global environment, then you should be able to pick it up from any process. The global environment is defined in the file /etc/launchd.conf, and it makes sense for a variable such as CATALINA_HOME to be defined there. Otherwise, best would be to let the tomcat team change their install procedure to either change /etc/launchd.conf, or to call `launchctl setenv CATALINA_HOME /path/to/tomcat` sometime when tomcat launches. Last, you can still parse the configuration file that sets CATALINA_HOME, whether it's ~/.profile, ~/.bash_rc or whatever. Note: user environment used to be defined in ~/.MacOSX/environment.plist, but it seems it's not supported any more in Mac OS X 10.8. Regards, Jean-Denis
