title: Haml syntax: split a line to a couple of rows
body: <p>I use HAML in my rails project for my html templates.
  I would like to figure out if its possible to divide a very long line and make it a couple of rows:</p>
  
  <pre><code>%a.open-service{href: '#', data: {
    service_name: service.description,
    balance_type: "coinsurance",
    total: service.a_total_billed - service.a_rejected - service.a_not_covered, 
    discount: service} }
  </code></pre>
  
  <p>As you can see, I just want to have an anchor with href and some data-attributes, and making it one-line won't be a pretty code.
  But when I do it like above I get an error: "Unbalanced brackets."</p>
  
  <p>any help?</p>
