This plugin allows you to use SCSS files directly in wp_enqueue_style. Just add the file to the list of styles and the plugin will compile it when necessary.
The base of this plugin is strongly influenced by the <a href="https://wordpress.org/plugins/wp-scss/" rel="ugc">WP-SCSS</a> code and extracts some ideas from <a href="https://wordpress.org/plugins/sassify/" rel="ugc">Sassify</a>. The goal is to keep the plugin updated with the latest version of <a href="https://packagist.org/packages/scssphp/scssphp" rel="nofollow ugc">scssphp</a>, remove configuration options from the graphical interface, and use the scssphp capabilities to create debug files.
This plugin is not intended to be installed by a conventional user, but to be required by templates or plugins that wish to include SCSS style files and therefore the configuration is expected to be done in the code.
