title: How to set an empty attribute using Jade?
body: <p>When using <a href="http://jade-lang.com/" rel="nofollow">jade</a>, <a href="https://angularjs.org/" rel="nofollow">AngularJs</a> and <a href="https://angular-translate.github.io/" rel="nofollow">angular-translate</a> I prefer to use the translate directive as an empty attribute.</p>
  
  <p>But for some reason, when using empty attributes in Jade, instead of getting something like <code>&lt;tag translate</code> OR <code>&lt;tag translate=''</code>, I'm getting <code>&lt;tag translate='translate'</code></p>
  
  <p>How can I add an attribute without a value?</p>
