    .init_rails(binding)  ⇒ Object 
  

  

  




  

    

This method is called by init.rb, which is run by Rails on startup. We use it rather than putting stuff straight into init.rb so we can change the initialization behavior without modifying the file itself.

    .version  ⇒ Object 
  

  

  




  

    

Returns a hash representing the version of Haml. The :major, :minor, and :teeny keys have their respective numbers. The :string key contains a human-readable string representation of the version. If Haml is checked out from Git, the :rev key will have the revision hash.
