On the forum, only a select number of languages seems to be syntax highlighted. Specifically, only languages listed as ‘common’ at the highlight.js demo seem to enjoy this privilege.
I checked Haskell, Elm, F#, Elixir, Scala, Clojure, Julia, MIPS, … – all these are not highlighted, whereas the likes of C#, Python, Bash, CSS, diff, … are.
Like exercism itself, highlight.js needs volunteers to create the libraries. Language contributor checklist — highlight.js 11.7.0 documentation
I’ve been meaning to do this for jq, but haven’t taken the time yet.
For all languages I listed these libraries are available. See the All category in the demo.
We’re just using a default Discourse installation, so you’ll need to report this upstream to them I think.
Ah, I expected it to be a setting somewhere.
I think each of the languages need to be installed as dependencies and compiled into whatever asset bundling they’re using so I imagine it’s not something they’d choose to widly support. (e.g. in our website’s package.json: website/package.json at main · exercism/website · GitHub)
Oh, I totally missed that. I was thinking “web editor”
