Hi Bob,
If at all possible I'd try and avoid the conversion. If this is not feasible,
this could help:

I've been continuing with my efforts to implement Fibers using GCD and in the
process I think I may have uncovered a Macruby bug - though perhaps it's a bug
in my code? Is there anything fundamentally wrong with the code posted below?
It consistently results in a EXC_BAD_ACCESS error.

Hi everyone,
I've had a go at implementing Fibers using dispatch queues. The code can be
found here:

Inspiration was taken from the following ruby 1.8 Fibers implementation:

The implementation of Fiber.yield currently relies upon a h
I'm glad things are now working as expected. My young cousins should be

I've also added support for multiple live video Santas.

Hi Laurent,
Thanks for the response. In essence the problem I have is something like this:

created which holds an instance variable to Object 'A'. 'B' is held in a hash
or array somewhere. Object 'B' only has a purpose whil
Hello everyone,
I've been doing some research into weak references in ruby and from what I've
read it seems that Ruby's WeakRef implementation is both inefficient and
unsafe. Here is the thread discussing the matter:

As Macruby has a different garbag
I think you've just managed to get your variable names mixed up. You've used

I think if you define an accessor for 'name' with attr_accessor as you have
done with someTextField, then this should work.
You can then remove the accessor methods you have created for the 'name'
instance var.

I've reduced the problem to the code below. Creating 1000 proxy objects in a

Warning, horrible hack alert!
I'm sure there must be a far better implementation, but the idea is to have an
array subclass which diverts all method calls through a serial dispatch queue,
which should ensure thread safe access.
Anyway, here's the horrible hack. By the way, it manages to break En

Has anyone had any trouble with NSPredicate causing occasional crashes when

When combining negative look-ahead with look-behind in a regexp, macruby
doesn't match correctly. Here's an example.
ruby 1.9.2

This is just a quick query about using 'include' in an xcode project.

Hello everyone,
I'm attempting to call a method on an Objective-C object which takes a block as
its parameter, but I'm not having much luck. I can happily create the object
in Macruby and send the message with a Proc. The NSLog call within the
Objective-C method body succeeds, but the 'block()'
