Open .xcworkspace file if exists or .xcodeproj otherwise. Useful for CocoaPods users. Found it elsewhere, but I can't find it anymore.

xopen

#!/usr/bin/env ruby

require 'shellwords'

proj = Dir['*.xcworkspace'].first
proj = Dir['*.xcodeproj'].first unless proj

if proj
  puts "Opening #{proj}"
  `open #{proj}`
else
  puts "No xcworkspace|xcproj file found"
end

This is currently under paulomendes/xopen.
