I'm using Haml as a quick way of prototyping layouts. This is not using Rails, Sinatra or any framework.
What I want to do is declare a variable at the top and be able to call it throughout the page, similar to the way I can declare a variable in Sass and use it throughout the code.
!!! 5
  %body
    / Declare Variable
    - $type = 'Audio'
    .container{:id => "page-#{$type}"}
Is this possible?
Drop the $ to avoid declaring a global variable. It should work just fine.
