On the MacRuby web site
by Scott Thompson 15 Jul '10

15 Jul '10

An item of curiosity more than anything else... I note that on the MacRuby.org web site, under the heading of "Why MacRuby?" the subheading of "Interpreter Performance"... it makes the claim that MacRuby is using YARV. Is this still the case? I was under the (perhaps mistaken) impression that LLVM was used as a replacement for YARV. Scott

[MacRuby] #796: Dispatch::Queue.main created with a different Queue class?!?

Ruby itself seems to think the classes are the same: $ macruby -r dispatch -e "p Dispatch::Queue.main.class == Dispatch::Queue.concurrent.class" true Concurrent queues work fine: $ macruby -r dispatch -e 'Dispatch::Job.new {sleep 1}.join(Dispatch::Queue.concurrent) {puts "!"}' as do private queues: $ macruby -r dispatch -e 'Dispatch::Job.new {sleep 1}.join(Dispatch::Queue.new("1")) {puts "!"}' I don't know if the problems is the class-equality check, or how the main queue gets a class assigned. -- Ticket URL: <http://www.macruby.org/trac/ticket/796> MacRuby <http://macruby.org/>

Presenting on MacRuby this evening
by Michael Jackson 15 Jul '10

15 Jul '10

I'll be giving a presentation on MacRuby tonight at the Utah Ruby User's Group. It's a pretty good group and has some very capable Rubyists, so it should be a fun time. If you're in the area, you might want to check it out. http://groups.google.com/group/urug/browse_thread/thread/292609271853115b# The main reason I'm posting to this list is to see if there's a good base of information to work from that has already been published elsewhere (for example, a recent presentation that someone else gave on MacRuby 0.6). Of course, I would be more than happy to give credit for any data/slides that I glean from other sources. I'll be sure to share whatever I come up with, perhaps on my GitHub account, so that it will be usable by others as well. I imagine there are others that are proselyting MacRuby that could benefit from such a resource. Thanks, Michael -- Michael Jackson http://mjijackson.com @mjijackson

Where are the rake tasks?
by Paul Howson 14 Jul '10

14 Jul '10

This might be a dumb question, but I notice mention of various macruby-related rake tasks (e.g "rake clean") Is there a standard set of rake tasks supplied with macruby? Where are the rake files for these tasks? ---------------------------------------------------------------- Paul Howson Warwick Qld Australia

MacRuby Graphics
by Matt Aimonetti 14 Jul '10

14 Jul '10

For those interested, I extracted HotCocoa::Graphics, started cleaning it up, added some specs and examples so you can enjoy the nice DSL built on top of Core Graphics. Feel free to fork and play with the repo: http://github.com/mattetti/macruby_graphics Examples and output in the readme. If you don't feel like contributing code, contributing examples and documentation would be awesome! - Matt p.s: it's s work in progress and it will probably take me a little while before I get decent code coverage. Also, Ryan David, note that used minitest ;)
