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.

This is a syntax highlighter plugin which also acts as an interface to the online compiler api service on cloud provided by https://www.compilebin.com. It interacts with cloud service via rest APIs i.e, submit the code and get the output. Users need to signup and get an api key which is to be updated in the plugin to use the service. Plugin contains a link for signing up for the service. There is no security concern on the web server as the task of code execution is offloaded to the cloud service. The plugin uses the following open source libraries : 
1) Code prettify for syntax highlighting 
2) Ace code editor 
Please visit https://www.compilebin.com for more information about the service.
