What?

DO NOT MERGE

This is a proof of concept for the Web Fonts API as an extension of the WP_Dependencies class.

It doesn't work quite yet. This is mainly to gauge whether this would be a feasible option to pursue further.

Why?

The current implementation re-implements a lot of the concepts that are already handled by WP_Dependencies for the script and style loaders. A WP_Web_Fonts class could potentially cut down on a lot of the code needed to implement a web fonts API.

The script loader classes already have the concepts of dependencies, enqueuing, and registering, as well as a way to "do_item()" (generate CSS or a <link> tag with source, in this case).

How?

This uses the following:

  • A font family is first registered. Behind the scenes, this registers an alias dependency (no script attached).
  • Font variations are registered independently with their own unique handle (which allows extenders to remove specific font variations), and added as dependencies for the font family alias.
  • Enqueuing the alias font family enqueues all registered variations for that family.
  • Individual variations can be enqueued separately.
