Modifying/using highlight.js

Can anyone give me some pointers?

It is done via


There is no existing hook to extend highlight js, but you can run decorateCooked in your plugin to apply further transforms to cooked.

There’s always the source code :wink:


Yeah, guess that would work :slight_smile:

I’ll toy around with this a bit later on and see how to get some javascript to fire on every load
