Missing language for syntax highlighting

[EmpathyMonster]

I'm trying to get syntax highlighting working for a programming language called Hare. The documentation says the Haskell library skylighting is used. If i visit that repo, the .xml file is missing, and it says to add it upstream at KDE (there's a link to this on the skylighting readme github page). Hare has been added upstream to KDE, but it appears it has not made its way into skylighting and therefore is not in Pandoc. I'm not an expert at software, so I would really appreciate some guidance on how to proceed to get the syntax highlighting working for Hare with Pandoc to create a pdf file. Thank you so very much for any help. If you need additional info, please let me know.

After reading through the docs, I was able to take the hare.xml file in the KDE repo and use the --syntax-definition option with Pandoc from the command line and I have syntax highlighting for Hare working now.
