How to change lower case to upper using regular expressions in Visual Studio Code : <p>I'm using Visual Studio Code 1.14.2, and I'm trying to change name of variables to camelCase eg.
<code>set_nominal_wavelength</code> to <code>setNominalWavelength</code>.</p>

<p>Regular expression: <code>_([a-z])</code></p>

<p>Replace: <code>\U$1\E</code></p>

<p>does not work. Any idea how to achieve it?</p>
