Am I missing a way to change tab/indent size in online editor? It seems to be 4 for most languages, but I’d really prefer 2.
I don’t think that’s something you can configure. If you want a custom dev environment, most people just work locally.
It should adhere to the norms for that language, or if there is not a norm, then the maintainers have chosen one.
The relevant settings are here (e.g. Ruby): ruby/config.json at main · exercism/ruby · GitHub
