using coffeescript on windows

If you want to develop with CoffeeScript outside of Rails, here’s one way you could do it:

• download the coffee.exe executable from CoffeeScript compiler for Windows
• copy coffee.exe in a folder that is on the PATH
• create a watchr file, for the ruby gem watchr. This way, everytime you modify the .coffee file, the js file gets recompiled. Here are the contents of my watchr file:

  
  watch("js/application.coffee") do |s|
  	puts "#{Time.now} => Compiling #{s}"
  	system("coffee -c #{s[0]}")
  end
  

• start watching the file for modifications:

  
  watcher your_watch_file.rb
  
  
  

• add the include for the resulting JS in your html code and you’re done
