Hi Henry, > This doesn't explain why MacRuby can't be implemented with ARC rather than > relying on the OBJ-C 2 garbage collector. Do You know what the difference between Garbage Collection and Reference Counting?
Current MacRuby VM implementation heavily depends on presence of GC. Potentially You could modify it to use ARC instead. The question is how much time do you need to spent on it and how you plan to support C extensions? Again, please, watch the end of Joshua Ballanco talk at BostonRB ( http://bostonrb.org/presentations/macruby-what-is-it-and-why-should-i-care-part-1 ) when he talk about issues of porting MacRuby to iOS. It isn't an issue to move MacRuby to it's own GC, there even was some efforts to do it https://github.com/takuma104/iphone-macruby On 17 окт. 2011, at 23:28, Henry Maddocks wrote: > > On 17/10/2011, at 7:11 PM, Igor Evsukov wrote: > >> Hi Henry, >> >>>> And it's impossible to make Ruby to use ARC. >>> >>> Why? >> For memory management Objective-C uses a paradigm called "reference >> counting". > > ... > >> In Ruby we have garbage collector which is acts in whole different way > > I understand all this.
