Hi @system, If I were to develop another markdown syntax highlighter (such as `json`, `http`, etc) would it be a [markdown-it](https://github.com/markdown-it/markdown-it) plugin such as [markdown-it-sub](https://github.com/markdown-it/markdown-it-sub)? If not, can you please direct me where I could learn more about writing new markdown syntax highlighter? Best ---

Syntax highlighter would be neither 🙂 Have a look at: [https://highlightjs.org/](https://highlightjs.org/) we are on version 9.13.1 ---

Thanks @Sam_Saffron! I've sent a PR to highlight.js so they add support to Kibana Dev Tools syntax [https://github.com/highlightjs/highlight.js/pull/1924](https://github.com/highlightjs/highlight.js/pull/1924) I am not sure when/if they will merge that. Do you think we could look into adding that change into the version used by you? ---

I don't think this will be merged ☹ but I think we can achieve this with a theme component here cause its simply a client side change. It is a bit tricky cause we defer load highlight so we would have to teach the client that ... when it defer loads highlight it injects this. So you mind doing a post asking about how to add custom highlighter on [https://meta.discoruse.org](https://meta.discoruse.org) I will assign this out to a member of our team? ---

Thanks for replying! I will ask how to add a custom highlighter, but I thought that, since you use highlight.js, then it's basically adding another language syntax support to highlight.js, which is what I did in that PR. ---

I follow, if it is merged it will be no problem at all we will update highlight.js and be done. Its just that looking at it I am not sure it will be merged, so I think you will need a discourse specific customisation. ---

What if a patch is generated from the changes? Is it something that can be applied to the version used here? ---

It is not that easy, loading the patch is tricky, we can get this applied, I will track this official request and get back to you ---

This is SO GREAT! Thank you very much! Yes! I will let you know when/if gets merged. I've been trying to ping the authors with no luck. Will keep trying. ---
