I put together an Objective-C version of this same thing and checked it into 
the github project for comparison. It works. I'm sure there's something 
different in how I'm using it, but I can't see what. The project is at:

[email protected]:sxross/MacRuby-Array-Cocoa-Array-Binding.git

That's both MacRuby and Objective-C. Any pointers to my blind spot are 
appreciated :)

Comment(by ernest.prabha...@…):

 Not directly relevant to your question, but you can also use GCD directly
 via the Dispatch module.  The basic Queue and Group functionality should
 be solid in the latest top-of-tree, which I think would address your
 needs.

 Thanks Ernie. However, I'm writing a section on some common Foundation
 classes and a chapter on concurrency programming with MacRuby so, even
 though GCD will be mentioned as the best option, I still need to cover the
 other existing solutions ;)

[MacRuby-devel] [MacRuby] #553: Fixnum Does Not Appear to Map to NSNumber

#553: Fixnum Does Not Appear to Map to NSNumber

 In the context of Cocoa Bindings, Fixnum should "magically" convert to
 NSNumber much as String becomes NSString. Example:

 {{{
 irb(main):001:0> i = 123.to_i
 => 123
 irb(main):002:0> i.class
 => Fixnum
 irb(main):003:0> n = NSNumber.numberWithInt(i)
 => 123
 irb(main):004:0> n.class
 => Fixnum
 }}}

 See project: http://github.com/sxross/MacRuby-Array-Cocoa-Array-Binding/

 for a more concrete example of why this is important.

 Why just manually setting it ourselves isn't ideal:

Hi,

Is there an equivalent of the NSAssert macro in MacRuby?

Re: [MacRuby-devel] Cocoa Binding to NSArrayController

2010-01-12 Thread John Shea 
Perhaps it is this bug here: https://www.macruby.org/trac/ticket/473

In my case with the current 0.5 beta2 no float or integer binding to nscontrol 
works (I get all 1's) unless the float or integer is converted to an 
NSDecimalNumber using a ValueTransformer.
This is what i use for each float binding as a work around:

class ToDecimalTransformer < NSValueTransformer 
def self.transformedValueClass; NSDecimalNumber.class; end

def self.allowsReverseTransformation; true; end 

def transformedValue(value)
NSDecimalNumber.decimalNumberWithString(value.to_s)
 end
  
def reverseTransformedValue(value)
new_val = value.to_f
end
end

HTH,
John

Yes, this appears to be the bug, and yes, this is an absolutely great (!!!) 
temporary fix. Thanks very much for this.
