Absolutely stellar work! ❤️❤️❤️ Thanks so much for pulling through. I fully subscribe to the motivation and the full extent of the proposal. Once implemented, it will surely eliminate a significant source of friction for contributors and maintainers.
Great piece of writing, and a beautifully painted bike shed.

Adopting https://github.com/NixOS/nixfmt as nix formatter for now, mainly because * NixOS/rfcs#166 has been accepted and it seems that nixfmt aims to be the primary implementation * nixfmt is clearly being actively maintained * nixfmt does `let` blocks (mostly) as I prefer (although I wish it uncomprimisingly put `in` block on new indented line.

This is the long-awaited rework of RFC 101, to establish an official and standard Nix formatting and formatter. In short:
Check it out
The initial standard Nix format is mostly implemented in this nixfmt PR.
There may be bugs, and it may not yet correspond entirely to this RFC, but it's fairly close.
It is packaged in Nixpkgs as
nixfmt-rfc-style.To see Nixpkgs formatted using it: https://github.com/piegamesde/nixpkgs/tree/nixfmt-2
Context
This RFC is the successor to RFC 101, which originally proposed the idea of a standard formatter. The RFC started out slow, mainly trying to pick an existing formatter, but it didn't really get off the ground. Only in January 2023 when @infinisil scheduled bi-weekly calls with the shepherd team, continuous progress was made:
With almost a year of discussions, a lot of work went into this and the RFC changed completely. It would be disingenuous to continue it as the original RFC, which is why we're opening it as a new one. All 4 original shepherds are pretty happy with this RFC as is, but we're looking forward to receiving feedback. Since original shepherds @piegamesde and @infinisil are now authors of the new RFC, we're also looking to find 1-2 new shepherds to fill the gap.
The original shepherd team will continue meeting bi-weekly on Tuesday 20:00 CET here, and is reachable on Matrix.
