Coding Style

Python Version

Use the accompanying .editorconfig or .dir-locals.el.
For Python files we use the style from ruff format with a line length of 109 characters and four spaces indentation.
Indentation with tabs is not allowed.
When it improves readability, judicious use of # noqa: E501 comments is allowed.
Long lists, including argument lists, should have a trailing comma to force ruff to split all elements on a line of their own.
List of commandline arguments should not split the argument of a commandline option and the option. This needs to be enforced with # fmt: skip comments, e.g. do
```
cmd = [
    "--option", "foo",
]  # fmt: skip
```
and do NOT do
```
cmd = [
    "--option",
    "foo",
]
```
When coercing Path-like objects to strings, use os.fspath, since this calls the __fspath__ protocol instead of __str__. It also ensures more type-safety, since every Python object supports __str__, but not all support __fspath__ and this gives the typechecker more information what is expected at this point. It also signals the intent to the reader more than a blanket str().
