Ruby script to automate running js2coffee against existing javascript folders

js2coffee_converter.rb

#!/usr/bin/env ruby

#run from within a folder containing your .js files
#each file will be converted to a .coffee file and copied to ../coffeescripts
#respects nested directory structure, creating what's necessary

Dir.glob("**/*.js").each do |file|  
  `mkdir -p ../coffeescripts/#{file_path = file.gsub(/[\/]?[^\/]*\.js/, "")}` unless file_path == ""
  `js2coffee #{file} > ../coffeescripts/#{file.gsub(/\.js/, "")}.coffee`
end
