Agenda & Notes

@piegames has decided to step down from the formatting team, effective today. We thank them for all their contributions since the initial RFC efforts and wish them the best going forward!
- https://github.com/NixOS/nixos-homepage/pull/1891
Discussed https://github.com/NixOS/nixfmt/pull/353
Did a group code review of Add automated CI workflow for releases by FlashOnFire · Pull Request #354 · NixOS/nixfmt · GitHub
For next time: we have too many issues marked as “TODO” that we’re not actively working on. Let’s trim that list down: https://github.com/orgs/NixOS/projects/63/views/6

Proposal for the team to discuss/address the Implement treefmt's (nascent) Stdin Spec · Issue #305 · NixOS/nixfmt · GitHub, `nix fmt` broken · Issue #301 · NixOS/nixfmt · GitHub, Add a Stdin Specification by jfly · Pull Request #586 · numtide/treefmt · GitHub issues. Is there a recommended way forward or to unblock? Anything needed from Nix Team?

I was waiting for treefmt’s stdin spec to get implemented and approved (something I haven’t had any time to work on) before changing nixfmt to implement the spec.

We also could totally change nixfmt’s behavior before treefmt’s stdin spec is finalized, though. That would be a more minor change, at least for someone with some Haskell knowledge. I’ll poke at it and see if I can put something together!

I took a stab at this here: Implement treefmt's stdin spec by jfly · Pull Request #358 · NixOS/nixfmt · GitHub. I do not know Haskell, help appreciated =)
