This extension provides syntax highlighting for the following WordPress syntaxes that exist inside traditional comment blocks:

• Plugin header fields (PHP)
• Block patten fields (PHP)
• Theme header fields (style.css)
• Block markup (HTML + JSON)

Examples

HTML

CSS

PHP

Additional Features

The Syntax Highlighter also implements rules for pattern/header field validation based on the following official documentation:

• https://developer.wordpress.org/block-editor/reference-guides/block-api/block-patterns/
• https://developer.wordpress.org/themes/advanced-topics/block-patterns/
• https://developer.wordpress.org/plugins/plugin-basics/header-requirements/
• https://developer.wordpress.org/themes/basics/main-stylesheet-style-css/

Unmatched brackets cause error highlighting inside the embedded JSON of WordPress blocks
