Enabling Eslint on typescript files
<p>On webstorm eslint setting, there is an "extra eslint options" field.
In this, I added: </p>

<pre><code>--ext .ts
</code></pre>

<p>from the eslint <a href="http://eslint.org/docs/user-guide/command-line-interface#ext" rel="noreferrer">documentation</a> which is supposed to allow eslint to work on custom file extension, in this case .ts files.
This does nothing. Is my syntax wrong ? Anyway to enable Eslint on .ts files, maybe from the .eslintrc file ?</p>
