Gary,

 Thanks for the info.

I'm surprised you say there could be size problems in the produced app. Do you mean that if I write the same app using IB and hotcocoa the last one would be sensibly larger ? Why ?

Vincenzo,

There was work on HotCocoa at least as recently as Jan 11, 2011, I think.

Here is the github graph of changes:

Unfortunately, I think it is an effort off to the side of the macruby team and core developers that hasn't gotten much attention. I know many (including myself) would like to see it succeed though. It was a lot of fun to work with for the few days that I did, and fun toys that you can create cool things with quickly can often do really well. The main problems I think have been the lack of attention, lack of development, and the large size of the produced application, at least in earlier versions.

Hello all,
 I discovered macruby since a few weeks and I'm really enthusiast.
I begun playing with it and really like the hotcocoa approach, but it seems stopped since more than a year, is it still maintained ?

Anyway, I think I found a bug in the hotcocoa canvas part: the text method draws at a very big size regardless of the chosen font. The problem is that the transformation matrix for the text is not set.

Here is the fix if anyone needs it:

module HotCocoa::Graphics
 class Canvas
   def text(txt="A", x=0, y=0)
     affine = CGContextGetCTM(@ctx)
     CGContextSetTextMatrix (@ctx, affine);
     txt = txt.to_s unless txt.kind_of?(String)
     if @registration == :center
       width = textwidth(txt)
       x = x - width / 2
       y = y + @fsize / 2
     end
     CGContextShowTextAtPoint(@ctx, x, y, txt, txt.length)
   end
 end
end
