[MacRuby] #446: Dispatch::TIME_FOREVER too big for signed long long

#446: Dispatch::TIME_FOREVER too big for signed long long -------------------------------+-------------------------------------------- Reporter: niklas@… | Owner: lsansonetti@… Type: defect | Status: new Priority: minor | Milestone: MacRuby 0.5 Component: MacRuby | Keywords: gcd semaphore long long TIME_FOREVER -------------------------------+-------------------------------------------- Dispatch::TIME_FOREVER is 18446744073709551615 so it fits into a unsigned long long. When you call "wait" with TIME_FOREVER on a semaphore the function in gcd.h (l. 826) uses NUM2LL(time) to convert the time in to a signed long long which leads to {{{ core:in `wait:': bignum too big to convert into `long long' (RangeError) from untitled:1:in `<main>' }}} I've seen this in MacRuby 0.5 beta 2 -- Ticket URL: <http://www.macruby.org/trac/ticket/446> MacRuby <http://macruby.org/>

#787: MacRuby Initializers only claim a single arity ----------------------------------------+----------------------------------- Reporter: ernest.prabhakar@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: MacRuby 0.7 Component: MacRuby | Keywords: ----------------------------------------+----------------------------------- When I write an initalizer, I only register it for a single arity: rb_objc_define_method(cQueue, "initialize", rb_queue_init, 1); Queue.new("foo") Unfortunately, Objective-C will apparently fall back to the default (no- arg) initializer of the superclass, leading to an uninitalized object being allocated if I mistakenly call: Queue.new # no args To work around this, I've manually added an exception-throwing initializer: static VALUE rb_raise_init(VALUE self, SEL sel) { rb_raise(rb_eArgError, "initializer called without any arguments"); return self; } rb_objc_define_method(cQueue, "initialize", rb_raise_init, 0); Would be nice if MacRuby did this automatically, to preserve Ruby-esque semantics. -- Ticket URL: <http://www.macruby.org/trac/ticket/787> MacRuby <http://macruby.org/>

When is a String not an NSString?
by Henry Maddocks 13 Jul '10

13 Jul '10

With respect to the following code 1 require 'test/unit' 2 3 class String 4 def my_method 5 "My Method " + self 6 end 7 end 8 9 class Test_Tumblr < Test::Unit::TestCase 10 11 def test_strings 12 cocoa_string = NSString::stringWithString("blah") 13 ruby_string = "Ruby String" 14 15 assert_equal String, cocoa_string.class 16 assert_equal String, ruby_string.class 17 assert_equal cocoa_string.class, ruby_string.class 18 19 assert ruby_string.respond_to?(:my_method), "ruby_string.respond_to?" 20 assert cocoa_string.respond_to?(:my_method), "cocoa_string.respond_to?" 21 end 22 23 end What is the expected result of line 20? On the one hand cocoa_string is an NSString so the monkey patch shouldn't have any effect, but on the other cocoa_string is claiming to be a ruby String. Henry

Document-Based Application Issues
by Mike Leonard 13 Jul '10

13 Jul '10

Hello all, Apologies if this is really obvious; my background is mainly in Ruby, though I do have some experience developing a Cocoa document-based app. Anyway, I'm trying to create a document-based application from the MacRuby template. Things started out well, but I hit a snag when I tried to get my app to actually open files. When I do File > Open, an NSOpenPanel pops up as expected, but after I select a file I just get a dialog telling me that the file could not be opened. In fact, the "readFromData(data, ofType:type, error:outError)" method never seems to execute at all. I'm sure this is something simple. I've basically been trying to apply the techniques in Apple's "Building a Text Editor in 15 Minutes" document to a MacRuby document-based app. Do I need to subclass NSDocumentController or something? Thanks, Mike Leonard

[MacRuby] #783: Patch for builder.rb error: invalid byte sequence in US-ASCII

#783: Patch for builder.rb error: invalid byte sequence in US-ASCII -------------------------------+-------------------------------------------- Reporter: slewsys@… | Owner: lsansonetti@… Type: defect | Status: new Priority: major | Milestone: MacRuby 0.7 Component: MacRuby | Keywords: -------------------------------+-------------------------------------------- As of MacRuby subversion Revision: 4343, following build instructions per ./README.rdoc fails with error message "invalid byte sequence in US- ASCII". This is a known issue with Ruby 1.9 which can be resolved by adding an argument to IO.open/read. In the case of MacRuby's builder.rb, changing File.read(src) to File.read(src, { :mode => "rb" }) resolves the issue. Patch follows: {{{ Index: rakelib/builder/builder.rb =================================================================== --- rakelib/builder/builder.rb (revision 4343) +++ rakelib/builder/builder.rb (working copy) @@ -142,7 +142,7 @@ end def locate_headers(cont, src) - txt = File.read(src) + txt = File.read(src, { :mode => "rb" }) txt.scan(/#include\s+\"([^"]+)\"/).flatten.each do |header| p = header_path(header) if p and !cont.include?(p) }}} -- Ticket URL: <http://www.macruby.org/trac/ticket/783> MacRuby <http://macruby.org/>

testing?
by Ryan Davis 10 Jul '10

10 Jul '10

So are you guys not testing your macruby code? I was hoping that the ruby community would bring the testing culture to the cocoa world and make it a better place. Having gotten no feedback/suggestions whatsoever on my testing setup has me a bit wary.
