title: How to configure sublime's build system to capture file and line from such error output?
body: <p>If I don't understand wrong, sublime can capture file and line number from error output, by configure the <code>file_regex</code> or <code>line_regex</code>.</p>
  
  <p>I have such error output:</p>
  
  <pre><code>  main.&lt;anonymous closure&gt;.&lt;anonymous closure&gt;   file:///Users/freewind/dev/workspace/RythmDart/test/test_grammar.dart 135:19
  </code></pre>
  
  <p>How to configure the build file?</p>
  
  <p>I tried:</p>
  
  <pre><code>"line_regex": "([\\w/:\\-_]*) (\\d*):(\\d*)",
  </code></pre>
  
  <p>But it doesn't work.</p>
