do not upgrade CouchDB until I push a new release of CouchRest
by Matt Aimonetti 09 Mar '09

09 Mar '09

Today a new syntax change was introduced and if you upgrade couch, it will break the current apps. I have a patch ready and I'll push it tonight or so. You will need to upgrade couch after I do that and bundle the gems, but I'll let you know. - Matt

Recent changes cause gem statement to fail
by M. Scott Ford 06 Mar '09

06 Mar '09

Hello, I just grabbed the latest from trunk (r831), and the following section from my rakefile causes the macruby process to hang. It seems to be the gem call that is causing the problem. Commenting that line out allows execution to proceed. I will keep investigating, but wanted to report this early. I would really like to see this fixed before 0.4 is released. Thanks, -Scott ENV['GEM_PATH']=File.expand_path("#{File.dirname(__FILE__)}/vendor/ gems") require "rubygems" Gem.clear_paths gem_paths = [ File.expand_path("#{File.dirname(__FILE__)}/vendor/gems") ] Gem.send :set_paths, gem_paths.join(":") gem 'cucumber'

Porting Cocoa OpenGL sample code
by Julien Jassaud 06 Mar '09

06 Mar '09

Hello, I am trying to port the Cocoa OpenGL sample to MacRuby and encountered a few problems. First, I can't access some constants defined in an enum in GLTypes.h. Do I need to port those constants to ruby by hand ? Is that related to gen_bridge_metadata ? Second, I need to use CGLQueryRendererInfo and CGLDescribeRenderer functions. The first one requires a pointer to a CGLRendererInfoObj structure but the second requires the object to be passed directly. I tried some C style pointer arithmetic : info = Pointer.new_with_type("CGLRendererInfoObj") count = Pointer.new_with_type("l") CGLQueryRendererInfo(caps[:cgl_display_mask], info, count) <- works fine, but CGLRendererInfoObj is opaque so I can't check it in irb. CGLDescribeRenderer(info[0], 0, kCGLRPRendererCount, count) <- I naively tried to dereference the pointer, but it doesn't work. CGLDescribeRenderer(info, 0, kCGLRPRendererCount, count) <- No complaints, but the value for count[0] is not consistent (100468704 renderers). I see in MacIRB that there is a CGLRendererInfoObj class but I can't instantiate it. This is all new to me and I may be overlooking something obvious. If anyone has an idea, please help. Thanks, Julien Jassaud

Scanning Unicode strings for non-ascii characters
by Robert Schaaf 04 Mar '09

04 Mar '09

Hello all, This may be obvious, but in a Unicode world it's driving me nuts. Given an arbitrary string, which may contain unicode characters, how do I replace all characters not in the range 0x20..0x7e with spaces? Thanks for any guidance, Bob Schaaf AIU Holdings

[MacRuby] #223: net/http in macruby 0.3 (ruby 1.9) has fatal bug
by MacRuby 02 Mar '09

02 Mar '09

#223: net/http in macruby 0.3 (ruby 1.9) has fatal bug -------------------------------------+-------------------------------------- Reporter: eugene@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: MacRuby 0.4 Component: MacRuby | Keywords: -------------------------------------+-------------------------------------- This is a ruby 1.9 issue. But the version of the net/http library deployed with macruby 0.3 has a bug in the urlencode function. Writing simple code like the following throws an exception: require 'net/http' require 'uri' res = Net::HTTP.post_form(URI.parse('http://tweetburner.com/links'), {'link[url]'=> ARGV[0]}) See the following URL for the fix (and a patch file): http://redmine.ruby-lang.org/issues/show/472 It's probably fixed in the latest net/http build. -- Ticket URL: <http://www.macruby.org/trac/ticket/223> MacRuby <http://macruby.org/>
