🪴/ The Super Mega Formatters Post

A yet comprehensive attempt at listing all code formatters available.

Dec 24, 2024 – Caleb Jasik

There are a good number of code formatters under the sun. I've been wanting to build https://areweformattingyet.com for a while now, I figure it's worth starting here with a simple list of everything that's around. Let me know via bsky if I need to add something!

Relatedly, I want to try to set up fuzzing for all said formatters, since they're a pretty solid problem space for fuzzing, idempotent and well-scoped. See Checking for idempotency: a bodgey formatter fuzzer , and jasikpark/fuzz-prettier for more.

McYoung wrote a great post about an approach to formatters from first principles that makes me want to try my hand: https://mcyoung.xyz/2025/03/11/formatters/#fnref:80-cols
