How can I use haml within a coffeescript file?

Question

Is it possible to use haml within a coffeescript file in a rails 3.1 project?
What is the correct order of the file extensions?

My last try was that:

home.js.haml.coffescript

$ ->
  alert '#{@count}'

where @count is a ruby variable.

Answer 1

The correct order would be home.js.coffeescript.haml—you want the file to first be evaluated as Haml to give you your variables, then compiled as CoffeeScript, then finally served as JavaScript.

However, I strongly suspect that the Haml processor will choke on some CoffeeScript syntax. It would probably be safer to use ERB, which should work for your example.
