WP-Parser is the parser for creating the new code reference at developer.wordpress.org. It parses the inline documentation and produces custom post type entries in WordPress.
We are currently looking for contributors to help us complete the work on the parser.
There is a guide to developing for developer.wordpress.org in the WordPress documentation handbook
Clone the repository into your WordPress plugins directory:
git clone https://github.com/WordPress/phpdoc-parser.git
After that install the dependencies using composer in the parser directory:
composer install
Activate the plugin first:
wp plugin activate phpdoc-parser
In your site's directory:
wp parser create /path/to/source/code --user=<id|login>
