The just formatter always updates the timestamp

[jwillikers]

Describe the bug

The just formatter always updates the timestamp of the file regardless of whether the file is changed or not.

DEBU formatter | just: executing: /nix/store/0irlcqx2n3qm6b1pc9rsd2i8qpvcccaj-bash-5.2p37/bin/bash -euc for f in "$@"; do
  /nix/store/qj4vq5wqbjirx4x8l5z3w9wjgl8da4w6-just-1.36.0/bin/just --fmt --unstable --justfile "$f"
done
 -- .justfile
INFO formatter | just: 1 file(s) processed in 21.883899ms
DEBU file has changed path=.justfile prev_size=1266 prev_mod_time="2024-11-22 08:28:16 -0600 CST" current_size=1266 current_mod_time="2024-11-22 08:37:27 -0600 CST"

To Reproduce

Steps to reproduce the behavior:

1. Format once: treefmt-nix -c --formatters=just --verbose=2
2. Format again: treefmt-nix -c --formatters=just --verbose=2

Expected behavior

The file should not be reported as changed when it hasn't been.

System information

just is version 1.36.

Additional context

/cc @jbott

This should be brought up upstream ideally

This should be brought up upstream ideally

I've opened casey/just#2478

[jwillikers]

Fixed upstream in casey/just#2479

[mrshmllow]

It appears that atleast protolint and yamlfmt also do this

[zimbatm]

@mrshmllow can you open a new issue for each, and also check with upstream?

I'll close this one for now
