[MacRuby] #218: including a module which defines functions can mask functions of the same name in the including class
by MacRuby 20 Jan '10

#218: including a module which defines functions can mask functions of the same name in the including class -------------------------------+-------------------------------------------- Reporter: celtic@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: Component: MacRuby | Keywords: -------------------------------+-------------------------------------------- Simple explanation: classes A and B both define methods `foo', as does module M. A includes M before defining its own `foo', whereas B includes M afterwards. Given that A and B both call `super' in their `foo', it turns out that only A's `foo' ends up calling M's, whereas B's does not. Conclusion: including the module which defines the method after defining ones own causes it to be lost. I believe this is causes the problem first referred to in #215. Attaching a test case which verifies this behaviour. -- Ticket URL: <http://www.macruby.org/trac/ticket/218> MacRuby <http://macruby.org/>

record your pronunciation of MacRuby
by Matt Aimonetti 20 Jan '10

20 Jan '10

I found a really cool site that lets you record words with your own accent creating a bank of pronunciations from around the world. During your next break, why not taking 5 minutes and recording your pronunciation of MacRuby: http://www.forvo.com/word/macruby/ We already have Australian English, Italian, French but it would be awesome to have pronunciations from around the globe. - Matt

[MacRuby] #561: serialization/archiving of ruby and obj-c objects

#561: serialization/archiving of ruby and obj-c objects -------------------------------------+-------------------------------------- Reporter: mattaimonetti@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: MacRuby 0.6 Component: MacRuby | Keywords: -------------------------------------+-------------------------------------- In Ruby archiving is done using the Marshal class, while in Cocoa, the NSCoder abstract class is being used. On one hand, currently, in MacRuby, you can marshal down pure Obj-C objects and of course things don't look too good when they are restored. On the other hand, you can't archive Ruby objects using Cocoa API since Ruby objects don't implement the NSCoding protocol. We probably need to add NSCoder support in marshal And also add the NSCoding protocol methods to new MacRuby classes. -- Ticket URL: <http://www.macruby.org/trac/ticket/561> MacRuby <http://macruby.org/>

GCD and NSURLConnection
by Darrin Eden 18 Jan '10

Hi, I have yet to wrap my head around GCD, but that's not stopped me from breaking things anyway. I'd like to use an asynchronous queue with NSURLConnection. However, <http://gist.github.com/279665> results in a segmentation fault. Thoughts? Thanks, -- Darrin
