Class Method Details

.augment_template(source, path) ⇒ Object

Returns augmented HTML where the source is simply wrapped in an HTML comment with filepath info. Xray.js uses these comments to associate elements with the templates that rendered them.

This:

<div class=".my-element">
  ...
</div>

Becomes:

<!-- XRAY START 123 /path/to/file.html -->
<div class=".my-element">
  ...
</div>
<!-- XRAY END 123 -->
