URI specs
by dan sinclair 11 Aug '09

11 Aug '09

Hello, I started poking at the URI specs to see what I could get working. The attached patch was required to make the specs run (URI provides 11 arguments to initialize). I then started taking a look at why the equality spec fails and have tracked it back to the dup call not returning the same values in the duplicate object. This can be seen by doing a self.to_s and uri.to_s in the normalize function of lib/uri/generic.rb. self.to_s -> http://example.com/#fragMENT uri.to_s -> http://example.com/ For some reason, the fragment instance variable is being dropped from the duplicated object while all of the other instance variables are being copied over. You can see the same behaviour with the following script ------------ class Foo def initialize(a, b, c, d, e, f, g, h, i, j, k) @a = a @b = b @c = c @d = d @e = e @f = f @g = g @h = h @i = i @j = j @k = k end def to_s "#{@a} #{@b} #{@c} #{@d} #{@e} #{@f} #{@g} #{@h} #{@i} #{@j} #{@k}" end end f = Foo.new("a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k") g = f.dup puts f.to_s puts g.to_s ----------- titania:test dj2$ macruby ./dup.rb a b c d e f g h i j k a b c d e f g h i j false dan

Git or Subversion?

Hi, I was wondering, are we using Git or Subversion these days? If we're switching to Git, how does one migrate to it from an existing SVN repository. Thanks, -Conrad

new mspec formatter
by Matt Aimonetti 10 Aug '09

10 Aug '09

Dear all, To give us a better idea of the progress made in our efforts to pass all the ruby specs, we added a new mspec formatter. If you pass the -f option with the macruby format argument, the specs will run and give you a feedback on each major category (core, language, library). $ ./mspec/bin/mspec ci -I./lib -B spec/macruby.mspec :full -f macruby You could also use the shortened version: $ ./mspec/bin/mspec ci -I./lib -B spec/macruby.mspec :full -f mr Note that the skipped examples are examples that were tagged as not running or passing yet. Periodically someone (usually Eloy) checks that the tagged specs still fail or don't pass. That gives us an indication of what needs to be worked on. The formatter seems to have an artifact and makes one of the specs fails and being counted as an error. I'll be looking into that in the next few days to try to solve this annoying issue. (specs are wrapped using mspec instrumentation API and I'm probably doing something that interacts with the way a specific spec is assering a behavior) Regards, - Matt

Base64 specs
by dan sinclair 09 Aug '09

09 Aug '09

Hello, The attached patch marks some specs that don't execute on Ruby 1.9.2 for me. The other Base64 specs that are broken are due to the TODO in vm_method.c, rb_mod_modfunc to do with changing scope. dan

Problem with MacRuby in Objective-C project
by Jaromír Šiška 09 Aug '09

09 Aug '09

I experimented with using MacRuby in ObjC projects. When I tried evaluteFileAtPath: method it worked fine until I tried to import another Ruby file into file under evaluation. E.g. if I put into evaluated file require 'csv' and I get in the debug console: [Session started at 2009-08-09 17:00:51 +0200.] 2009-08-09 17:00:54.302 EmbedRubyFile[19113:10b] LoadError: no such file to load -- csv.rb.bundle ( "/Users/jsiska/TEMP/pp_pascal2.rb:4:in `require'", "/Users/jsiska/TEMP/pp_pascal2.rb:4:in `<dummy toplevel>'" ) Can anybody advice me where is the problem? Thank you Jaromir Siska

[MacRuby] #307: eval destroys a singleton attribute (Segmentation fault)

Disable it and everything works fine! $stderr.puts eval("42", TOPLEVEL_BINDING.dup, 'hotconsole', 100) # the next line crashes with: unknown: [BUG] Segmentation fault $stderr.puts @win.target.inspect $stderr.puts "everything is fine!" exit end end class Application def start application :name => "HotConsole" do |app| app.delegate = self Test.new.run end end end Application.new.start }}} gives the result: {{{ #-<Test:0x8004450a0> 42 unknown: [BUG] Segmentation fault MacRuby version 0.5 (ruby 1.9.0) [universal-darwin9.0, x86_64] Abort trap }}} Unfortunately enabling the "win.will_close..." causes the Segmentation fault to disappear on my system, so I hope other people will see the same behaviour! (obvisously this is memory layout dependant) BTW, I didn´t use NSLog because it crashes on my system: {{{ macruby -e "framework 'Cocoa'; NSLog 'test'" }}} gives: {{{ unknown: [BUG] Segmentation fault MacRuby version 0.5 (ruby 1.9.0) [universal-darwin9.0, x86_64] Abort trap }}} -- Ticket URL: <http://www.macruby.org/trac/ticket/307> MacRuby <http://macruby.org/>

Intro, looking to get involved
by Greg Vaughn 08 Aug '09

08 Aug '09

Hello, I thought I'd take a minute to introduce myself. I've seen a few posts of people having trouble building, but wanted to report that it went clean for me right off the bat. There's a few test failures and errors though. rake spec:ci Finished in 156.295783 seconds 1553 files, 6256 examples, 18175 expectations, 8 failures, 134 errors I pulled from the macruby-mirror github repo John-Paul Bader posted today. For starters, are those test failures/errors to be expected? If so, is the easiest way to get my feet wet to tackle some of those? Any in particular I should avoid because of the complexity for a newbie, or that someone else is deep into? My pedigree, in case that helps anyone nudge me in the right direction: taught myself BASIC in Jr. High, Apple II assembler in High School, C during college pursuing a Physics degree, first job in Newtonscript, Java (for a long time, too long), bought Pickaxe the hour it was released <g>. Lately I'm been directing my career more towards Ruby and Javascript. Last year was almost all Rails. I live in the Dallas area. I'm a husband and father, so my free time would not be considered copious, but I'm excited about MacRuby and will make time to help. -Greg Vaughn
