Hey Scott,

I'm sorry if I somehow gave you the idea that it felt as if you're  
being "critical".
Probably has to do with the fact that English isn't my native language.
But even then it would be very hard for me to feel that way ;)

Anyways, if you would by any chance take the effort to check out the  
code
and write some documentation I'd be more than happy to commit it.

Cheers,
Eloy

OK.

Please understand wasn't trying to be critical.  I was just trying to  
find out if I had missed out on some documentation that might have

I appreciate the help!

Hi Scott,

Unfortunately the sources are the docs...
I believe this was because there's no final API yet,
although Laurent might be able to say more about that.

[Rubycocoa-talk] documentation for OSX.require_framework and the like

[Scott T. <ea...@ma...>]

I was wondering where I might look to find documentation for  
OSX.require_framework.  I tried "ri" and "nothing was known" about  
require_framework.

The reason I ask is because I was trying to write some code that uses  
rubycocoa and ImageIO.  It took me quite some time to figure out how  
to make ruby aware of the ImageIO framework.  I was originally trying  
to include the ApplicationServices umbrella framework:

OSX.require_framework 'ApplicationServices'

But that didn't pull in the component frameworks.  After searching  
around I found that I could use:

OSX.require_framework '/System/Library/Frameworks/ 
ApplicationServices.framework/Versions/Current/Frameworks/ 
ImageIO.framework'

I prefer the "cleaner" way that the ApplicationServices framework came  
in above.

I wanted to know if there was a "cleaner" way to import the  
constituent frameworks of an umbrella framework, but couldn't really  
find any documentation on "require_framework" and what it does, or  
does not accept as a parameter.

Is there a source for documentation of methods like require_framework  
or init_for_bundle?  These are both methods that I found out about  
after quite a lot of fruitless searching.  If there's a better  
resource available to learn about this kind of "hidden" rubycocoa  
method, I'd love to look at it.

I have been struggling with this myself recently. I've never written a
RubyCocoa application (am only just getting started now) but I think
I've figured it out.

I wrote a summary about it here: http://freudian.tumblr.com/post/31305332

[Rubycocoa-talk] Do you use GDB with RubyCocoa programs?

[Brian M. <ma...@ex...>]

I'm writing some text about how to debug RubyCocoa programs. In  
particular, I'm trying to help people who've done something wrong that  
leads to a blowup down in some NSClass. For example, suppose I use  
textfield.intValue to set text in some NSTextView, rather than  
textfield.stringValue. That leads to this error:

2008-04-08 08:46:46.314 Flat Fenestration[27099:10b] *** -[NSCFNumber  
length]: unrecognized selector sent to instance 0x730db0
2008-04-08 08:46:46.330 Flat Fenestration[27099:10b]  
FenestrationController#chooseWebapp: OSX::OCException:  
NSInvalidArgumentException - *** -[NSCFNumber length]: unrecognized  
selector sent to instance 0x730db0

The problem is that somewhere something is trying to take the length  
of an integer object. GDB 'backtrace' produces a trace of ObjC message  
sends that could be, in theory, useful. In this case, it isn't. But it  
might be if I could get descriptions of the args. I can't do that with  
the standard libraries:

(gdb) frame 20
#20 0x946d81a8 in -[NSView interpretKeyEvents:] ()
(gdb) info args
No symbol table info available.

I was hoping I would get more information if I used the _debug  
versions of the frameworks (as set in the executable's General Info  
pane under "Use ______ suffix when loading frameworks" but all that  
produces is a flood of these messages:

warning: Could not find object file "/var/tmp/Libm/Libm-287.1~6/ 
Libm.build/Libm_debug.a.build/Objects-normal/i386/xmm_arcsincostan.o"  
- no debug information available for "/SourceCache/Libm/Libm-287.1/ 
Source/Intel/xmm_arcsincostan.c".

... and the same lack of symbol table information.

I am wondering if it's worth continuing to try to dig for useful  
things you can do with GDB. Are there any?

[Rubycocoa-talk] Calling Ruby class methods from Objective-C

[Scott T. <ea...@ma...>]

I have a ruby class which defines a class method:

def MyClass
	def MyClass.doSomethingInteresting
		... blah blah blah ...
		return someObject;
	end
end

I'd like to call this method from Objective-C so I tried something  
like this:

Class myClass = NSStringClassFromString(@"MyClass");
id myObject = [myClass performSelector:  
@selector(doSomethingInteresting)]

But this gives me an unrecognized selector warning on the console and  
fails.

Is it possible to call a ruby class method from Objective-C?

   Yes. The new version of Frictionless: http://www.twinforces.com/frictionless/ 
  does this. I don't do iCal Event/Calendar syncing though, because I  
would need to hugely extend iCals Event model, which I've been avoiding.

> Any issues ?

  Yes.

   Do you have any kind of backtrace exception to start with?

   Meanwhile, add this to all your objects:

    def objectEnumerator
       print "Object Enumerator called\n"
    end

   I don't know why, but Sync Services likes to call this.

   Are you using CoreData as well? In Leopard, syncing when you start  
from a Core Data model is much simpler.

[Rubycocoa-talk] SyncServices and a custom SyncSchema

[Rupert B. <rup...@fr...>]

Hi,

I have been doing SyncServices for some time in RubyCocoa : in Tiger,  
I used to use Harmonize's syncservices.rb, now replaced by  
OSX.require_framework 'SyncServices' in Leopard's RC.

Up to now, I have been syncing data into Apple's Schema : Contacts,  
Phone Numbers, Addresses, Events, Calendars, etc.

I have just started testing syncing data into my own SyncSchema : my  
SyncSchema is registered, and gets updated properly when I add/modify  
attributes (I see it in Syncrospector); however, on my first  
SLOW_SYNC, my RubyCocoa app crashes with an "illegal instruction" when  
trying to write this new data into the sync engine. RC debugging gives  
no more details.

Has anyone done this before ?  Any issues ?
Any other idea, anyone ?


TIA,
Rup

    There's this new "MacRuby" thing that Apple's working on that's  
pretty slick. Since Leopard has garbage collection, the new MacRuby  
takes Ruby 1.9 (which also has a JIT compiler) and makes all Ruby  
objects full fledged ObjC objects.

    End result, it will work even better then RubyCocoa does now, full  
threading will be supported, etc.

think we will need true multi-threaded runtimes.  Is that work

Re: [Rubycocoa-talk] SIGABRT on Bus Error

[Eloy D. <e....@su...>]

Hey Avram,

This could mean a lot. And as you've noticed there's isn't any one  
answer to it...
It could for instance be that you're referencing an object which  
doesn't exist anymore,
or something to do with threading etc etc.

The best way I can think of to solve it is by taking parts of your  
application down
and see when it stops happening. Then when you know roughly in which  
code
it happens you turn on debugging by doing: $RUBYCOCOA_DEBUG = true
which will start to print lots of info.

Good luck!

[Rubycocoa-talk] SIGABRT on Bus Error

[Avram L. <aj...@gm...>]

Hello all!

I've been working on a small application using RubyCocoa for some
time, and I keep getting unexpected and seemingly inexplicable
crashes, with the message:
"/Development/Mac_Plans/build/Debug/Mac_Plans.app/Contents/Resources/rb_main.rb:23:
[BUG] Bus Error"

Digging around on the web, it doesn't look like there's a clear
explanation anywhere of what I should even look at to address this.

Is there any way to get more meaningful debugging information for this
kind of thing?

To answer my own question, after looking at samples on the web that  
use RBBundleInit, it appears that the invocation I was missing is this:

require 'osx/cocoa'
OSX.init_for_bundle do |bundle, additional_param, consoleLog|
   # bundle - The bundle being initialized.  Presumably an NSBundle?   
Passed as second param to RBBundleInit
   # additional_param  - Whatever you passed to RBBundleInit in the  
third parameter
   # consoleLog    - Used to pass NSLog messages to the console
   # ...do something here...
end
Experimentally, I was able to determine that I can use a similar block  
with RBApplicationInit.  However, since I have no real need to get at  
command line arguments, and given that this mechanism was recommended  
here, I'll stick with this.

Thank you.  I will try it.

However.  I don't want to pass "nil" as the additional_param, I want  
to pass an object. Inside of my Ruby program, how do I find the object  
that I pass into the additional_param parameter?

Scott

Re: [Rubycocoa-talk] Getting at the "Param" argument to RBApplicationInit

[kimura w. <ki...@us...>]

Hi,

I think RBBundleInit() is suited for your purpose.
The interface of RBBundleInit is like this.

  // <RubyCocoa/RBRuntime.h>
  int RBBundleInit (const char* path_to_ruby_program,
                    Class       objc_class, 
                    id          additional_param);
                  
  - path_to_ruby_program:
    path of ruby script in the bundle. e.g. "main.rb".
    RubyCocoa expects the path as related path from Resources/.

  - objc_class:
    an ObjC class to specify your bundle. e.g. AppDelegate.

  - additional_param:
    you can pass nil.

[Rubycocoa-talk] Getting at the "Param" argument to RBApplicationInit

[Scott T. <ea...@ma...>]

On Mac OS X (Leopard), I'm trying to embed Ruby into an Objective-C application (as opposed to writing a Cocoa application in Ruby).  I've got it working, but I was curious about one aspect.

To initialize Ruby, I'm calling RBApplicationInit to initialize Ruby.  I know how to get at the argc and argv parameters, but the last parameter, the "id" valued parameter... how is that passed to the Ruby script named in the first parameter of RBApplicationInit?

Hi Shane,

AFAIK there hasn't been any progress to make RubyCocoa work under the  
ObjC GC mode, simply because supporting that in an efficient way would  
require too much work, like modifying the internals of the Ruby

[Rubycocoa-talk] Sporadic selector not recognized errors

[Benjamin J. <bhj...@gm...>]

Every now and then I get the following error:
2008-03-22 15:12:41.817 Blogo[20434] *** -[MGTwitterClient
requestSucceeded:]: selector not recognized [self = 0x17b93bf0]
/Users/bjackson/working/blogo/trunk/Blogo.app/Contents/Resources/rb_main.rb:35:in
`NSApplicationMain': NSInvalidArgumentException - *** -[MGTwitterClient
requestSucceeded:]: selector not recognized [self = 0x17b93bf0]
(OSX::OCException)

The behavior seems random, and the function for the selector exists and
works most of the time. Any idea what might be up?

Thanks,

Ben

[Rubycocoa-talk] Example of using Mac Keychain?

[Praful K. <pra...@gm...>]

Hi

There was a discussion about using the Mac keychain but no example.
Looking at the API docs, I see that I need to use
KeychainAddGenericPassword and KeychainFindGenericPassword. However, I
don't know how to call these from RubyCocoa. An example would be
appreciated.

Thanks

Praful

Re: [Rubycocoa-talk] How do I use RBObject.h on Leopard?

[kimura w. <ki...@us...>]

Hi,

config.h refered from osx_ruby.h is located into 
/usr/lib/ruby/1.8/universal-darwin9.0.
Add the directory as "Header Search Paths" to your project.
