Packing gems in the app's folder
by Thiago Jackiw 27 Mar '09

27 Mar '09

Do I have to do anything special to pack gems inside my application's folder? The following isn't working when I require the gems inside of my 'Gems' folder: # rb_main.rb ENV['GEM_HOME'] = File.dirname(__FILE__) + '/Gems' require 'rubygems' require 'mechanize' `require': no such file to load -- mechanize (LoadError) If I do the above in IRB it works just fine. The 'Gems' folder contains the following structure: Gems - cache - doc - gems - mechanize-0.9.2 - specifications - mechanize-0.9.2.gemspec Thanks, and I'm using MacRuby 0.4. -- Thiago Jackiw

[MacRuby] #235: Problems with adding objects to scriptable applications via scripting bridge

#235: Problems with adding objects to scriptable applications via scripting bridge --------------------------------+------------------------------------------- Reporter: i.script@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: MacRuby 0.4 Component: MacRuby | Keywords: ScriptingBridge Error --------------------------------+------------------------------------------- hi, lately I've tried to get some exerience in scripting DEVONthink using the ScriptingBridge. This works overall very well. Only the "create a record with in" command crates headaches for me. The following code-snippet exemplifies the problem: {{{ #!/usr/local/bin/macruby framework "Cocoa" framework "Foundation" framework "ScriptingBridge" devon = SBApplication.applicationWithBundleIdentifier("com.devon- technologies.thinkpro2") theGroup = devon.createLocation '/root/scripts/myscript', :in => '/' theRecord =devon.classForScriptingClass("record").alloc.initWithProperties({'type'=>'text','plainText'=>"Hallo Welt!",'name' =>"helloworld"}) puts theRecord.description # Scripting Bridge does not actually create an object in the target application until you add the allocated and # initialized object to an appropriate element array (SBElementArray), such as records in my example. # thats's the way it should be done, but its not working puts devon.databases[0].records.insertObject(theRecord, :atIndex => 11) # or : puts devon.databases[0].records.addObject(theRecord) theRecord.createRecordWithIn resultRecord }}} While working with this code snippet I've found out that: 1. if i use: "puts theRecord" instead of "puts theRecord.description" the script runs out of time 2. the attempt to instantiate a scripting object within DEVONthink creates this error: {{{ /Users/stereocle/Documents/devonruby.rb:24:in `insertObject:atIndex:': NSGenericException: Apple event returned an error. Event = 'core'\'crel'{ 'kocl':'DTrc', 'insh':'insl'{ 'kobj':'obj '{ 'want':'DTrc', 'from':'obj '{ 'want':'DTkb', 'from':'null'(), 'form':'indx', 'seld':1 }, 'form':'indx', 'seld':1 }, 'kpos':'befo' }, 'prdt':{ 'DTpl':'utxt'("Hallo Welt"), 'pnam':'utxt'("helloworld"), 'DTty':'utxt'("text") } } (RuntimeError) Error info = { ErrorNumber = -10000; }}} -- Ticket URL: <http://www.macruby.org/trac/ticket/235> MacRuby <http://macruby.org/>

Interfacing with C (not objective C)
by Martin Hess 18 Mar '09

18 Mar '09

My apologies if this has been covered somewhere else, but how do you interface with C in MacRuby. I know you can just write a C extension for Ruby but it appears that MacRuby makes this easier but it is unclear to me how far its support goes and when you should write an extension. Someone was asking about OpenGL in another thread which is a great example of a more difficult case but I don't think it covers all cases in a general sense. I'll break up the problem as I see it: 1) External C routines can be asynchronous a) Memory handed to the asynchronous routine can't move i.e. no garbage collection b) Call backs (i.e. passing in function pointers to a C routine) i. Asynchronous routines can show up at anytime 2) Function pointers as parameters to external C routines a) Function signature has to match exactly i.e. can't pass in a Ruby method pointer 3) Memory a) Allocated by external C routine i) How to delete if it is the callers responsibility to delete b) Allocated by caller i) How to allocate and get valid pointer to memory that isn't going to get garbage collected away c) Reading and writing allocated memory i) This is raw memory with no type information ii) How do you give it shape so you can read and write symbolically i.e. no peek/poke iii) Reading and writing packed bitfields So how are each of these things done in MacRuby?

I am an old dog learning new tricks by reading. I remember that when I was a young dog, I learned better by doing. So I would like to help someone do something. I have experience writing unit tests and documentation, but would like to do anything.

How do I handle file drop events in HotCocoa?
by Jeff Cohen 17 Mar '09

17 Mar '09

Hello, I'm just getting started with MacRuby and HotCocoa (was a longtime .NET developer, and wasn't interested in learning Cocoa until MacRuby came along). I have a simple HotCocoa app with just a table view, and I'd like the user to be able to drop a filename from the Finder onto the table view (or anywhere in my app). I can call registerForDraggedTypes() on my table view object successfully. But I'm not sure how to have events delegated to my Application class (or if that's even possible). Looking at the hotcocoa source for wrapping NSView (view.rb), I don't see delegate mappings for the draggingEntered or performDragOperation events. I think I need to do something like the mapping code does and write code like this: delegating "draggingEntered", :to => :dragging_entered but I don't know where I can or should do that, or if I'm even on the right track. Any hint of where I should get started would be appreciated. Thanks! Jeff

Introduce myself and some questions
by Ferhat Ziba 16 Mar '09

16 Mar '09

Hey guys, My name is Ferhat Ziba, I am student in Hamburg and study computer science. I saw your project and it's awesome. I like the Idea developing os x apps in ruby as first citizen programming language. After I get my fingers dirty with playing arround the source code, I have some questions : 1. Where are the path to the mapping files from hotcocoa ? I found it in the repository but not on my local machine. (I use the prebuild binary package on the project site for installing macruby). I like to extend some functionality for my (experimental) opensource project. 2. When I write some mapping files ? Where should I send it ? I got some other questions, like how licence checking for comercial apps, but I think for this questions the project is to much in early state. Macruby and hotcocoa are great Stuff. Ferhat Ziba
