Improve extractor for arbitrary values with quotes #4817

merged 1 commit into from Jun 26, 2021

Fixes #4801.

This PR improves our default extractor regex to handle arbitrary values that are wrapped in quotes more precisely.

Previously, given this input:

<h1 class="<?php echo wrap(['class' => 'max-w-[16rem]']); ?>">Hello world</h1>

...we would find a class named max-w-[16rem]']. This PR makes sure we find max-w-[16rem] instead, while preserving the ability to match things like content-['hello'] and even content-[']'].

We don't match this properly yet: content-['hello[]'], but we also didn't before this PR, so this is still purely an improvement over what was there before.

Since the regex is getting long, I've also broken it up into 4 parts with a few comments for each piece to explain what it's for.
