I added this for now:
call s:hi("erubyDelimiter", s:nord15_gui, "", s:nord15_term, "", "", "")

Hi @roelandmoors 👋, thanks for your contribution 👍

Actually it should be colored with nord10 due to the default linking to the PreProc groups so I wonder why its not working. Anyway, feel free to submit a PR which explicitly adds this syntax group.

@roelandmoors Thank you for your patience! 🙏🏼
It‘s been a while since I had free time to focus more on Nord, and my open source projects in general, and invest time in this issue due to work-life balance.

I recently published the first “Northern Post — The state and roadmap of Nord“ announcement which includes all details about the plans and future of the Nord project, including the goal of catching up with the backlog. This issue is part of the backlog and therefore I want to triage and process it to get one step closer to a “clean state“. Read the announcement about reaching the “clean“ contribution triage state in Nord‘s discussions for more details about the goal.

Therefore it has been added to the queue in the central and single-source-of-truth project board that is also described in more detail in the roadmap announcement.
