I’d like to add syntax highlight support for a proprietary language we support. After various searches on google and on this forum, I can’t find the documentation and/or examples. Would appreciate pointers.
Thanks

I think that discourse use: `highlight.js` - [We're not a CDN - highlight.js](https://highlightjs.org/static/demo/)
Check this: [(old) method for adding languages to highlight.js on Discourse](https://meta.discourse.org/t/hack-to-install-a-new-language-for-highlight-js-on-a-hosted-discourse/55818)
