quick-and-dirty clipboard usage in ruby (OS X/Linux)

clipboard.rb

class Object
  unless method_defined?(:clip) || !self.respond_to?(:to_s)
    def clip # won't work in windows, but I doubt it'll ever be an issue...
      if RUBY_PLATFORM.downcase.include?("darwin")
        IO.popen('pbcopy', 'w+') do |clipboard|
          clipboard.write(self.to_s)
        end
      elsif RUBY_PLATFORM.downcase.include?("linux") #requires xsel to be installed
        IO.popen('xsel --clipboard --input', 'r+') do |clipboard|
          clipboard.puts self.to_s
        end
      end
      self
    end
  end
