nixfmt puts quotes in the wrong place and breaks this file

[Ramblurr]

nixfmt --version
nixfmt v0.6.0

• Affected file: https://gist.github.com/Ramblurr/0463c3ba20948ce7b84203c699264a59

Reproduce:

# fetch file
curl https://gist.github.com/Ramblurr/0463c3ba20948ce7b84203c699264a59/raw/8552947240dbd2d927eb16b6d9a6550692368867/dynamic-wallpaper.nix --output dynamic-wallpaper.nix

# format once
nixfmt dynamic-wallpaper.nix

# format again
nixfmt dynamic-wallpaper.nix

Result:

dynamic-wallpaper.nix:130:13:
    |
130 |         hour="$(date +%k | xargs)" # xargs removes leading whitespace
    |             ^
unexpected '='
expecting expression

..and the file is broken.

Unfortunately I cannot reproduce. Could you please try minimizing your example, and also make sure you are using the latest master branch?

[Ramblurr]

I switched from the unstable nixpkgs nixfmt to the one provided by the flake in this repo, and I can also no longer reproduce.

If you want the nixfmt from nixpkgs unstable, you can use nixfmt-rfc-style which is the new style :)

[Ramblurr]

Ah is there a difference?

Which repo should I report this bug to then because the unstable nixfmt is definitely breaking that file.

Edit:

Oh not pkgs.nixfmt but pkgs.nixfmt-rfc-style. I'll try that one and report back.
