Option to use highlightjs for syntax highlighting

[harpocrates]

The API for highlightjs seems to be pretty much the same as prettyify. I think both are quite widely used. However,

• highlightjs is actively maintained and developed while prettyify is no longer maintained
• highlightjs supports more languages

Would it be feasible to add an option for choosing the syntax highlighting library to use?

Sure, I would be OK with switching to highlightjs and dropping prettify.

Are you in a position to suggest the necessary changes in a PR?

Not yet - I wanted to check this would be well-received first before moving forward with the actual changes. Are you sure it is OK to drop prettify, or should it be kept around as an option (checking as I imagine highlightjs will have subtly different syntax definitions and color schemes such that code in existing doc projects like akka-docs might end up looking slightly different)?

I don't think it is a problem if the syntax colouring slightly changes. highlightjs seems to offer a vast set of predefined designs. Configuring that will be more useful than switching between prettify and highlightjs.

OK thanks; that definitely lowers the bar for changes I'd have to make/test. I'll aim to open a PR for this in the next week or so.

Going straight for highlightjs seems fine to me too.

I'm not sure if the fiddle integration interacts with the syntax highlighting at all - that might be one thing to double-check.

Switching to highlightjs sounds good to me too. Thanks @harpocrates
