Add Sass support

[wookiefriseur]

Sass support would be nice.

The scss parser in Prettier does not seem to support Sass as of yet.
See #11 (comment)

Let's check Prettier updates from time to time or find a good alternative combining all stylesheet languages.

Any suggestions are welcome.

Tried a few formatters and so far only https://github.com/TheRealSyler/sass-formatter worked well
Looks promising, will have to check how to best load and call it (maybe creating a prettier-plugin would make sense, if compatible)

I'm not currently working on it, just a note for later

This looks pretty good! 😃 🚀
Thanks for the research.

If you are ok with it and you didn't start working yet, tomorrow, I would check out whether creating a prettier-plugin out of it would be a proper solution.
They have to be compatible.
