is hotcocoa dead ?
by Vincenzo Piombo 24 Mar '11

24 Mar '11

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

MacRuby and the UIKit framework for Mac OS X
by B. Ohr 24 Mar '11

24 Mar '11

Hi, I ported a small demo the UIKit framework for Mac OS X (http://chameleonproject.org/) to MacRuby. Although the framework is not currently known to be GC-safe it is working for me: https://gist.github.com/884875 I will do further investigations in this topic because I want to learn UIKit and playing around with MacRuby is much faster than with Obj-C.

Proposal: splitting macrubyc UI from logic
by Mark Rada 24 Mar '11

24 Mar '11

Hi, I have completed a proof of concept patch for MacRuby where I have split the UI of macrubyc from the underlying logic so that tools like macruby_deploy can make use of the compiler without having to spawn a new macruby process for each file that needs to be compiled. This should also be beneficial for compiling gems and the standard library. After having made this patch, I realized that there are still several places in the compiler where a new process is spawned to perform part of the compilation. I'm not really sure how much else can be lib-ified from the other required components. Overall there are still a few places that I know I can optimize without much work needed. Right now, compile time for ruby files with about 100-200 lines of code is about 1(+/-0.1) seconds on my MBP. Spawning a new macruby process and processing the macrubyc options takes about 0.25 seconds; so I think the patch is still useful in the general case. The code for the changes is located in my MacRuby fork on github: https://github.com/ferrous26/MacRuby/tree/libify-rubyc Mark Rada mrada(a)marketcircle.com

Xcode 4 LLVM >= r127367
by Dave Lee 24 Mar '11

Can the LLVM that comes with Xcode 4 be used to compile MacRuby 0.10? Is there a way to determine which svn revision Xcode's LLVM was compiled from? thanks, Dave

[ANN] MacRuby 0.10
by Laurent Sansonetti 24 Mar '11

24 Mar '11

Hi, After just a couple weeks of development since the last release, MacRuby 0.10 is now available. Get it here while it's still hot! MacRuby is an implementation of Ruby 1.9 directly on top of Mac OS X core technologies such as the Objective-C runtime and garbage collector, the LLVM compiler infrastructure and the Foundation and ICU frameworks. It is the goal of MacRuby to enable the creation of full-fledged Mac OS X applications which do not sacrifice performance in order to enjoy the benefits of using Ruby. You can learn more about MacRuby, and download a binary installer, from the website: http://macruby.org Or about this release more specifically, on our blog: http://www.macruby.org/blog/2011/03/23/macruby010.html Enjoy, Laurent

0.10 - update
by Laurent Sansonetti 23 Mar '11

23 Mar '11

Hi guys, As the Xcode4 templates seem to be functional, I just branched trunk for the 0.10 release. I will do more testing and hopefully, 0.10 should be released either tonight or tomorrow! Development continues in trunk, which is now using the 0.11 version number. Laurent

Why the MacRuby does not implement cref?
by Takao Kouji 23 Mar '11

23 Mar '11

Hi, I'm trying to fix issues below. - #619: Constant scope in a block is determined at run-time? - #828: A NameError, raised from evalling, gets the wrong constant name. - #1095: Segfault on uninitialized constant in Rspec2 test - #1167: NameError: uninitialized constant Hpricot::Container::Trav::Traverse - #1192: Did not find nested constants. But, I could not find like cRuby's cref variable in compiler.cpp. I am wondering why the MacRuby does not implement cref? Also, I am thinking about implementing cref myself. I wonder if anyone would be opposed to this? Thanks Kouji. --- TAKAO Kouji <kouji(a)takao7.net> blog: http://d.hatena.ne.jp/kouji0625/ twitter: takaokouji / projects: ruby, s7-seven

CATextLayer.font
by Ben Koski 23 Mar '11

23 Mar '11

I'm having trouble trying to set the font property on a CATextLayer using the latest version of macruby. I've noticed that there is already a ticket for an issue when trying to set the font using a NSFont instance (http://www.macruby.org/trac/ticket/1114) I tried using CGFontCreateWithFontName('Georgia') to create the font reference, with similar results (expected instance of Pointer, got `#<__NSCFType:). CTFontCreateWithName didn't work either. Does anyone here have an ideas/suggestions for workarounds? The rest of the CATextLayer properties seem to work fine, it's just font that causes errors. Ben

Is your MacRuby App in the App Store?
by Derek Haynes 23 Mar '11

23 Mar '11

>From past discussions, it seems completely possible for a MacRuby app to be accepted into the App Store. However, I've only been able to find one actual example: http://www.quora.com/Ruby/Are-there-any-MacRuby-apps-on-the-Mac-App-Store If your app is in the App Store, would you mind sharing a link? I think it would dispel any myths about the issue. It's a common question I've received from others in the Ruby community and links to actual apps would go far.

xcode4 templates - update
by Laurent Sansonetti 23 Mar '11

23 Mar '11

Hi guys, I know some of you are waiting for the Xcode4 templates. Some work has been committed to trunk. You should be able to create new MacRuby projects from Xcode4 (basic, document-based, core-data based or preference pane). Each template has a Deployment target builtin that will call macruby_deploy with --compile --embed (you can customize the arguments if needed). Also, a basic .rb File template is provided. According to Matt there is still a problem with the CoreData template, but besides that, I think it's good enough for 0.10. Please give trunk or tonight's nightly build a try and let us know what you think! Thanks, Laurent
