title: regex var extract without a dot
body: <p>I have a string:</p>
  
  <pre><code>"{balba $aaa = $bbb.test == $ddd == $sdfsf.dfgdfg.dfg}"
  </code></pre>
  
  <p>I tried to create a regex that extract all vars without a dot.</p>
  
  <p>Expected result is:</p>
  
  <ol>
  <li>$aaa</li>
  <li>$ddd</li>
  </ol>
  
  <p>My regex is <code>\$[a-zA-Z0-9_]*[^\.]</code> but it does not work.</p>
