A Flarum extension. Server-side code highlighting with cached results.

For each code block of the posts, a hash is computed while parsing them, then on render the code highlighting is done in the backend once, and stored in the cache for future renderings.

It provides the following advantages:

  1. The highlighting is done on the server so it is not up to the clients to do it.
  2. The server uses the cache to save highlighted blocks to only do the processing once.
  3. It works without any JS so even on the worst web browser the highlight will be there and there is no delay before the highlighting is applied.
  4. The theme adapts itself to the "dark mode" setting of Flarum.
  5. It works even with BBCode extension disabled.
  6. Admins can choose the highlight theme for both "Light" and "Dark" Flarum variants.
  7. Admins can download highlight themes with highlight:download Flarum console command.
  8. It is compatible with fof/nightmode by switching the highlight theme accordingly.

Client-side highlighting is still used, but only for the post preview.
