Source code inclusions require highlightjs?

[pitosalas]

First of all, please tell me if there's a different place for me to post a question like this. Is there a forum or a discord channel?

I have lots of source code in my slides and I have been using highlightjs. Highlightjs does not have a feature for line numbers. And yet I have seen examples of revealjs pages with source code highlighted.

How is that done? A different code highlight package? Is there a sample or some doc on how to do that? My ideal code block in a presentation would have line numbers and smart copy/paste (where the line numbers are not copied.)

Thank you!

Hi Pito, you are correct that this is not the right place. “Discussions” would be more fitting for questions like this. As for a short answer (and not hard to find): https://revealjs.com/code/.

Yes, I did find that and see that. The confusion is that highlight.js says that it doesn't do line numbers: https://highlightjs.readthedocs.io/en/latest/line-numbers.html . So when I saw line numbers on one of the pages I thought maybe you were using a different/seperate package for that :)

Hi @pitosalas — we're using this highlight.js plugin to add line numbers: https://github.com/wcoder/highlightjs-line-numbers.js

I’ll move this to discussions.

And for a copy functionality, you could try a plugin I made: Copycode.

Yes I saw that too, thanks!
