Re: [MacRuby-devel] URI and NSURL compatibility

8 Oct 2010

      This is Ruby, where everything is an expression. If you're going to be clever, why not go all the way?

---
def is_macruby?; defined?(RUBY_ENGINE) && RUBY_ENGINE == 'macruby'; end

if is_macruby?
  framework 'Foundation'
else
  require 'uri'
  COMPONENTS = [:scheme, :userinfo, :host, :port, :registry,
                :path, :opaque, :query, :fragment]
end

class HackURI < (is_macruby? ? NSURL : URI::HTTP)
  def initialize(uri)
    if is_macruby?
      self.initWithString(uri)
    else
      u = URI.parse(uri)
      super(*COMPONENTS.map { |c| u.send(c) })
    end
  end

  def what_am_I?
    puts self.class.ancestors
  end
end

h = HackURI.new('http://www.macruby.org')
h.what_am_I?

Although, you may want to rethink your strategy here…there's a REALLY BIG impedance mismatch between the way that the URI module is designed and the way NSURL works. Anyway, hope this helps…

Cheers,

Josh

A more efficient version of that class:
class HackURI
  if RUBY_ENGINE == 'macruby'
      def initialize(uri)
      	@url = NSURL.URLWithString uri
      end
  else
      def initialize(uri)
      	@url = URI.parse uri
      end
  end
def method_missing(method, *args)
      @url.send(method, *args)
  end
end

Hi devs,
I am trying to write a gem so that it will run on MRI and MacRuby, but still be able to take advantage of MacRuby things like Cocoa and GCD.
I was playing around with some URI related stuff and I cannot find much documentation on whether NSURL and URI objects have been bridged for MacRuby?
If they aren't bridged, I was thinking I could just hack together an empty class that just chooses if it inherits from NSURL or URI at run time.
Something like this:
require 'uri'
class HackURI 
      def initialize(uri)
      	 if RUBY_ENGINE == 'macruby'
      		@url = NSURL.URLWithString uri
      	 else
      		@url = URI.parse uri
      	end
       end
def method_missing(method, *args)
      	@url.send(method, *args)
      end
  end
