Sorting of some tables seems to be random

[edgarrmondragon]

Consider the following pyproject.toml:

[tool.ruff]
line-length = 88
src = [
  "src",
  "tests",
  "docs",
]

[tool.ruff.format]
docstring-code-format = true
preview = true

[tool.ruff.lint]
preview = true
select = [
  "F",
  "E",
  "W",
  "EM",
  "PD",
]

[tool.ruff.lint.per-file-ignores]
"src/*" = [
  "PD", # pandas-vet
]

[tool.ruff.lint.flake8-errmsg]
max-string-length = 30

Running pyproject-fmt (2.0.3) against it produces different results on sequential runs. I used the --check flag to confirm the randomness (as opposed to the result being affected by any previous changes made by the tool).

The following command was used then

pyproject-fmt --check pyproject.toml

No changes 😅

$ pyproject-fmt --check pyproject.toml
no change for pyproject.toml

Let me know if this better reported in https://github.com/tox-dev/pyproject-fmt-rust :)

Yeah I think this is https://github.com/tox-dev/pyproject-fmt-rust/issues/8

Ah this is probably a duplicate of https://github.com/tox-dev/pyproject-fmt/issues/205 and both are now fixed by #210.

EDIT: both are probably duplicate of https://github.com/tox-dev/pyproject-fmt/issues/201
