When creating a dict with string keys, some prefer to call dict instead of writing a dict literal.
For example: `dict(a=1, b=2, c=3)` instead of `{"a": 1, "b": 2, "c": 3}`.
- Implement N999 (following flake8-module-naming) in pep8_naming
- Refactor pep8_naming: split rules.rs into file per rule
- Documentation for majority of the violations
Closes https://github.com/charliermarsh/ruff/issues/2734
This rule guards against `asyncio.create_task` usages of the form:
```py
asyncio.create_task(coordinator.ws_connect()) # Error
```
...which can lead to unexpected bugs due to the lack of a strong reference to the created task. See Will McGugan's blog post for reference: https://textual.textualize.io/blog/2023/02/11/the-heisenbug-lurking-in-your-async-code/.
Note that we can't detect issues like:
```py
def f():
# Stored as `task`, but never used...
task = asyncio.create_task(coordinator.ws_connect())
```
So that would be a false negative. But this catches the common case of failing to assign the task in any way.
Closes#2809.
This PR adds a configuration option to inhibit ANN* violations for functions that have no other annotations either, for easier gradual typing of a large codebase.
I moved the `self.in_annotation` guard out of the version check in #1563. But, I think that was a mistake. It was done to resolve#1560, but the fix in that case _should've_ been to set a different Python version.
Closes#2447.
If `allow-multiline = false` is set, then if the user enables `explicit-string-concatenation` (`ISC003`), there's no way for them to create valid multiline strings. This PR notes that they should turn off `ISC003`.
Closes#2362.
Ruff allows rules to be enabled with `select` and disabled with
`ignore`, where the more specific rule selector takes precedence,
for example:
`--select ALL --ignore E501` selects all rules except E501
`--ignore ALL --select E501` selects only E501
(If both selectors have the same specificity ignore selectors
take precedence.)
Ruff always had two quirks:
* If `pyproject.toml` specified `ignore = ["E501"]` then you could
previously not override that with `--select E501` on the command-line
(since the resolution didn't take into account that the select was
specified after the ignore).
* If `pyproject.toml` specified `select = ["E501"]` then you could
previously not override that with `--ignore E` on the command-line
(since the resolution didn't take into account that the ignore was
specified after the select).
Since d067efe265 (#1245)
`extend-select` and `extend-ignore` always override
`select` and `ignore` and are applied iteratively in pairs,
which introduced another quirk:
* If some `pyproject.toml` file specified `extend-select`
or `extend-ignore`, `select` and `ignore` became pretty much
unreliable after that with no way of resetting that.
This commit fixes all of these quirks by making later configuration
sources take precedence over earlier configuration sources.
While this is a breaking change, we expect most ruff configuration
files to not rely on the previous unintutive behavior.
