[tool.codespell] ignore-words-list ignored in Python 3.9 and 3.10

[rvernica]

I have the following in pyproject.toml:

[tool.codespell]
ignore-words-list = ["iif", "DELETEing"]

In .pre-commit-config.yaml I have:

  - repo: https://github.com/codespell-project/codespell
    rev: "v2.4.1"
    hooks:
      - id: codespell

This works fine when pre-commit is run on Python 3.11 to 3.13. On Python 3.9 and 3.10 I get:

codespell................................................................Failed
- hook id: codespell
- exit code: 65

pyproject.toml:50: iif ==> if
pyproject.toml:50: DELETEing ==> deleting
foo/bar.py:74: DELETEing ==> deleting
foo/taz.py:4: iif ==> if

I also tried:

[tool.codespell]
ignore-words-list = "iif, DELETEing"

but the end result was the same.

Please don't send questions about pre-commit. For the purpose of opening an issue here, run codespelll standalone.

[tool.codespell]
ignore-words-list = ["iif", "DELETEing"]

For the purpose of testing, try this instead:

[tool.codespell]
ignore-words-list = "iif,deleteing"

[rvernica]

Using lowercase does not make any difference:

[tool.codespell]
ignore-words-list = ["iif", "deleteing"]

codespell................................................................Failed
- hook id: codespell
- exit code: 65

tests/test_db.py:2514: iif ==> if
pyproject.toml:50: iif ==> if
pyproject.toml:50: deleteing ==> deleting
scidbpy/be_clientapi.py:74: DELETEing ==> deleting

Using the codespell command line worked without issues.

Looking at the README I realized I was missing the tomli dependency in pyproject.toml:

 - repo: https://github.com/codespell-project/codespell
    rev: "v2.4.1"
    hooks:
      - id: codespell
        additional_dependencies:
        - tomli

Once added it worked as expected.

tomlib was added to Python as part of the standard library starting from 3.11, hence my issue with Python 3.9 and 3.10.
