alt Hacker NewsI'm surprised they went with a all-at-once reformat. Even when doing it over a weekend this is bound to mess with a lot of open PRs at their scale.
I had to introduce a formatter in a few sizeable codebases in the past (few 100k to few million LOC), and I always did it incrementally via a script that reformatted all files that are not touched in any open PR. The initial run reformatted 95% of all files. Then I ran the script every day for ~two weeks and got up to 99.5% of all files and then manually each time one of the remaining ~dozen PRs that were WIP for longer were merged.

It's probably because the author can shit on others (let me guess, a senior principal something engineer).
You can always let the team know so that they can apply the formatter on their PR branch.
both options have their pros and cons. if you utilize some form of ratcheting[1], you can sneak it in without your team knowing.. but all of your PRs for the foreseeable future will have a ton of reformatting screwing with your git blame. if you do it all at once, someone will have to sort out conflicts, but you can utilize `blame.ignoreRevsFile`[2] so that your history remains useful
