Please implement fork() ;-)
by robert gleeson 16 Apr '10

Hello, I know it has been discussed before and I haven't really gotten a final word back on it yet. With the removal of the GIL, and Grand Central Dispatch fork() isn't really needed to achieve concurrency _but_ I have a particular use case that requires fork() and I'd love to implement my use-case in a MacRuby cocoa application. I know fork() and CoreFoundation(iirc) can cause problems but if there is a work-around or solution I would _love_ to see it implemented. Thanks, Rob

#637: Segmentation fault error with NSSearchPathForDirectoriesInDomains function ---------------------------------+------------------------------------------ Reporter: aldarisb@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: MacRuby 0.5 Component: MacRuby | Keywords: NSSearchPathForDirectoriesInDomains "Segmentation fault" ---------------------------------+------------------------------------------ Hello MacRuby Team, I have a segmentation fault error with in a macruby class. To reproduce this problem with macirb tape follow lines : {{{ def function_test NSSearchPathForDirectoriesInDomains(NSDownloadsDirectory, NSUserDomainMask) end function_test }}} We should have the segmentation fault error. I reproduce this problem under an MacRuby Xcode Project. But if I use directly the "NSSearchPathForDirectoriesInDomains(NSDownloadsDirectory, NSUserDomainMask)", I don't have the error.

[MacRuby] #649: NSNumber bridging problem

#649: NSNumber bridging problem -------------------------------------+-------------------------------------- Reporter: eloy.de.enige@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: -------------------------------------+-------------------------------------- There seems to be an issue with NSNumber bridging on the current trunk. Here I have NSArrayController's selection index bound to a Ruby class which takes a selectionIndex: {{{ can't convert NSCFNumber to Integer (NSCFNumber#to_int gives NSCFNumber) (TypeError) }}} I think it boils down to this: Incorrect behavior on trunk: {{{ irb(main):001:0> NSNumber.numberWithInt(42).class => NSCFNumber }}} Correct behavior on older version: {{{ irb(main):001:0> NSNumber.numberWithInt(42).class => Fixnum }}} -- Ticket URL: <http://www.macruby.org/trac/ticket/649> MacRuby <http://macruby.org/>

Size of the apps
by Daniel Lopes 15 Apr '10

15 Apr '10

Hello, this is my first post here and I am new in the Apple Dev/MacRuby. I don't know if this the right mailing list, I don't found any other in the MacRuby site related to questions about development. So, if this mail isn't appropriate here please let me know. Some days ago, in a sample app, I tried to embed the MacRuby Framework to distribute the app as a standalone package but the size of the app became huge. There is some effort to make the embedded framework smaller or any tip/tricks that I should do to get small apps? Or all my apps will have 34mb? (It's not a big problem, just to know). Thanks. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Daniel Lopes - Area Criações Design, Websites e Sistemas Web http://www.areacriacoes.com.br/ http://www.cifrascash.com/ http://pomodo.areacriacoes.com.br/ http://egenial.com.br/cursorails twitter: @danielvlopes * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * 55 (31) 3077-4560 / 55 (31) 8808-8748 / 55 (31) 8737-7501

building a GUI in macirb
by Jakub Suder 15 Apr '10

15 Apr '10

Hi, is it possible to build a simple GUI (window, button, textfield, etc.) in the console (macirb), just for demonstration purposes? I tried that, but first I couldn't even construct a window (I was getting some horrible errors), I found somewhere that I need to call NSApplicationLoad() once, then I was able to build a window, but if I add something to its contentView it doesn't appear, and the mouse cursor is the spinning beach ball when I hover over that window. I assume I need to call something to let the app process the events in the queue, but I have no idea how to do that... is what I want to achieve possible? Best regards, Jakub Suder

Just started to play with macruby and would love to start working in 1.9 vs 1.8 more and esp the cocoa stuff vs. objc but... can someone give me the secret recipe to get some of the simple stuff to work... like macgem install sinatra I get this: unknown: warning: ignoring alias unknown: warning: ignoring alias unknown: warning: ignoring alias unknown: warning: ignoring alias unknown: warning: ignoring alias unknown: warning: ignoring alias unknown: warning: ignoring alias ERROR: While executing gem ...

Iconv and MacRoman
by Yvon Thoraval 14 Apr '10

14 Apr '10

Hey all, I've downloaded and installed the latest and get an error when attempting to convert from UTF-8 to MacRoman, here is the error message : /Library/Frameworks/MacRuby.framework/Versions/0.6/usr/lib/ruby/1.9.0/iconv.rb:40:in `ns_encoding:': unrecognized encoding `' (RuntimeError) from /Library/Frameworks/MacRuby.framework/Versions/0.6/usr/lib/ruby/1.9.0/iconv.rb:17:in `initialize:' from /Users/yt/dev/Signature/./change_signature_macruby.rb:199:in `block' from /Users/yt/dev/Signature/./change_signature_macruby.rb:192:in `change_signature:' from /Users/yt/dev/Signature/./change_signature_macruby.rb:65:in `parse_option:' from /Users/yt/dev/Signature/./change_signature_macruby.rb:4:in `<main>' the faulty script being : utf8_2_macroman = Iconv.new('MacRoman', 'UTF-8') la[i] = utf8_2_macroman.iconv(signature.split(/#{LF}/).join(CR)) it seems MacRuby isn't using the same iconv as ruby 1.9 because a similar sript, running well with Ruby 1.9, uses : la[i] = Iconv.conv('MacRoman', 'UTF-8', signature.split(/#{LF}/).join(CR)) however, with that line i get : /Users/yt/dev/Signature/./change_signature_macruby.rb:199:in `block': undefined method `conv' for Iconv:Class (NoMethodError) best, Yvon

Garbage Collector in MacRuby
by Daniel Lopes 11 Apr '10

11 Apr '10

Hello, I would like to know more about the garbage collector. In Obj-c even when we have GC enabled we should set nil to the vars (which sometimes is also useful in pure ruby). Correct me if I'm wrong but in MacRuby we can't use GDB, right? We still able to use profile tools? I should set all vars to nil or it will be treated like normal ruby code and I need set to nil only the objects that I want to be released now? Thanks.

Simple Example Fails
by Robert Love 11 Apr '10

11 Apr '10

I'm trying to learn Macruby and am using Apple's page as a guide: http://developer.apple.com/mac/articles/scriptingautomation/cocoaappswithma… I'm using macirb to follow the example and getting complete different answers. Is the web page wrong? Is Macruby wrong? Am I doing something wrong? irb(main):001:0> h = {} => {} irb(main):002:0> h.class => NSMutableDictionary irb(main):003:0> h.setObject 'foo', forKey:42 => {1=>"foo"} irb(main):004:0> Why isn't the key 42 like the Apple web page shows?

I suspect that no Apple employee will be able to comment on this, but I _really_ hope MacRuby will be among the blessed languages for the iPad, etc. -r -- http://www.cfcl.com/rdm Rich Morin http://www.cfcl.com/rdm/resume rdm(a)cfcl.com http://www.cfcl.com/rdm/weblog +1 650-873-7841 Technical editing and writing, programming, system design
