## Summary
This PR adds an experimental Ruff subcommand to generate dependency
graphs based on module resolution.
A few highlights:
- You can generate either dependency or dependent graphs via the
`--direction` command-line argument.
- Like Pants, we also provide an option to identify imports from string
literals (`--detect-string-imports`).
- Users can also provide additional dependency data via the
`include-dependencies` key under `[tool.ruff.import-map]`. This map uses
file paths as keys, and lists of strings as values. Those strings can be
file paths or globs.
The dependency resolution uses the red-knot module resolver which is
intended to be fully spec compliant, so it's also a chance to expose the
module resolver in a real-world setting.
The CLI is, e.g., `ruff graph build ../autobot`, which will output a
JSON map from file to files it depends on for the `autobot` project.
## Summary
Follow-up from #13268, this PR updates the test case to use
`assert_snapshot` now that the output is limited to only include the
rules with diagnostics.
## Test Plan
`cargo insta test`
## Summary
Follow-up to #13147, this PR implements the `AstNode` for `Identifier`.
This makes it easier to create the `NodeKey` in red knot because it uses
a generic method to construct the key from `AnyNodeRef` and is important
for definitions that are created only on identifiers instead of
`ExprName`.
## Test Plan
`cargo test` and `cargo clippy`

## Summary
The `SequenceIndexVisitor` currently does not recurse into
subexpressions of subscripts when searching for subscript accesses that
would trigger this rule. That means that we don't currently detect
violations of the rule on snippets like this:
```py
data = {"a": 1, "b": 2}
column_names = ["a", "b"]
for index, column_name in enumerate(column_names):
_ = data[column_names[index]]
```
Fixes#13183
## Test Plan
`cargo test -p ruff_linter`
## Summary
Extends deletions for RUF100, deleting trailing text from noqa
directives, while preserving upcoming comments on the same line if any.
In cases where it deletes a comment up to another comment on the same
line, the whitespace between them is now shown to be in the autofix in
the diagnostic as well. Leading whitespace before the removed comment is
not, though.
Fixes#12251
## Test Plan
`cargo test`
## Summary
Now that Ruff provides a formatter, there is no need to rely on Black to
check that the docs are formatted correctly in
`check_docs_formatted.py`. This PR swaps out Black for the Ruff
formatter and updates inconsistencies between the two.
This PR will be a precursor to another PR
([branch](https://github.com/calumy/ruff/tree/format-pyi-in-docs)),
updating the `check_docs_formatted.py` script to check for pyi files,
fixing #11568.
## Test Plan
- CI to check that the docs are formatted correctly using the updated
script.
## Summary
As suggested by @MichaReiser in
https://github.com/astral-sh/ruff/pull/12886#pullrequestreview-2237679793,
this adds an exemption to `RUF027` for `fastAPI` paths, which require
template strings rather than eagerly evaluated f-strings.
## Test Plan
I added a fixture that causes Ruff to emit a false-positive error on
`main` but no longer does with this PR.
## Summary
This PR is a pure refactor to simplify some of the logic for `RUF027`.
This will make it easier to file some followup PRs to help reduce the
false positives from this rule. I'm separating the refactor out into a
separate PR so it's easier to review, and so I can double-check from the
ecosystem report that this doesn't have any user-facing impact.
## Test Plan
`cargo test -p ruff_linter --lib`
This adds the `fast-api-unused-path-parameter` lint rule, as described
in #12632.
I'm still pretty new to rust, so the code can probably be improved, feel
free to tell me if there's any changes i should make.
Also, i needed to add the `add_parameter` edit function, not sure if it
was in the scope of the PR or if i should've made another one.
List and set comprehensions using `async for` cannot be replaced with
underlying generators; this PR modifies C419 to skip such
comprehensions.
Closes#12891.
## Summary
Occasionally, we receive bug reports that imports in `src` directories
aren't correctly detected. The root of the problem is that we default to
`src = ["."]`, so users have to set `src = ["src"]` explicitly. This PR
extends the default to cover _both_ of them: `src = [".", "src"]`.
Closes https://github.com/astral-sh/ruff/issues/12454.
## Test Plan
I replicated the structure described in
https://github.com/astral-sh/ruff/issues/12453, and verified that the
imports were considered sorted, but that adding `src = ["."]` showed an
error.
## Summary
This PR adds support for VS Code specific cell metadata to consider when
collecting valid code cells.
For context, Ruff only runs on valid code cells. These are the code
cells that doesn't contain cell magics. Previously, Ruff only used the
notebook's metadata to determine whether it's a Python notebook. But, in
VS Code, a notebook's preferred language might be Python but it could
still contain code cells for other languages. This can be determined
with the `metadata.vscode.languageId` field.

This brings us one step closer to fixing #12281.
## Test Plan
Add test cases for `is_valid_python_code_cell` and an integration test
case which showcase running it end to end. The test notebook contains a
JavaScript code cell and a Python code cell.
## Summary
This PR fixes a bug in the semantic model where it would evaluate the
default parameter value in the type parameter scope. For example,
```py
def foo[T1: int](a = T1):
pass
```
Here, the `T1` in `a = T1` is undefined but Ruff doesn't flag it
(https://play.ruff.rs/ba2f7c2f-4da6-417e-aa2a-104aa63e6d5e).
The fix here is to evaluate the default parameter value in the
_enclosing_ scope instead.
## Test Plan
Add a test case which includes the above code under `F821`
(`undefined-name`) and validate the snapshot.
## Summary
See #12703. This only addresses the first bullet point, adding a space
after the comma in the suggested fix from list/tuple to string.
## Test Plan
Updated the snapshots and compared.
In most cases we should suggest a ternary operator, but there are three
edge cases where a binary operator is more appropriate.
Given an if-else block of the form
```python
if test:
target_var = body_value
else:
target_var = else_value
```
This PR updates the check for SIM108 to the following:
- If `test == body_value` and preview enabled, suggest to replace with
`target_var = test or else_value`
- If `test == not body_value` and preview enabled, suggest to replace
with `target_var = body_value and else_value`
- If `not test == body_value` and preview enabled, suggest to replace
with `target_var = body_value and else_value`
- Otherwise, suggest to replace with `target_var = body_value if test
else else_value`
Closes#12189.
## Summary
Adding parentheses to a tuple in a subscript with elements that include
slice expressions causes a syntax error. For example, `d[(1,2,:)]` is a
syntax error.
So, when `lint.ruff.parenthesize-tuple-in-subscript = true` and the
tuple includes a slice expression, we skip this check and fix.
Closes#12766.
> ~Builtins are also more efficient than `for` loops.~
Let's not promise performance because this code transformation does not
deliver.
Benchmark written by @dcbaker
> `any()` seems to be about 1/3 as fast (Python 3.11.9, NixOS):
```python
loop = 'abcdef'.split()
found = 'f'
nfound = 'g'
def test1():
for x in loop:
if x == found:
return True
return False
def test2():
return any(x == found for x in loop)
def test3():
for x in loop:
if x == nfound:
return True
return False
def test4():
return any(x == nfound for x in loop)
if __name__ == "__main__":
import timeit
print('for loop (found) :', timeit.timeit(test1))
print('for loop (not found):', timeit.timeit(test3))
print('any() (found) :', timeit.timeit(test2))
print('any() (not found) :', timeit.timeit(test4))
```
```
for loop (found) : 0.051076093994197436
for loop (not found): 0.04388196699437685
any() (found) : 0.15422860698890872
any() (not found) : 0.15568504799739458
```
I have retested with longer lists and on multiple Python versions with
similar results.
Implements the new fixable lint rule `RUF031` which checks for the use or omission of parentheses around tuples in subscripts, depending on the setting `lint.ruff.parenthesize-tuple-in-getitem`. By default, the use of parentheses is considered a violation.

## Summary
Resolves#12636
Consider docstrings which begin with the word "Returns" as having
satisfactorily documented they're returns. For example
```python
def f():
"""Returns 1."""
return 1
```
is valid.
## Test Plan
Added example to test fixture.

## Summary
Removes set comprehension as a violation for `sum` when checking `C419`,
because set comprehension may de-duplicate entries in a generator,
thereby modifying the value of the sum.
Closes#12690.
## Summary
Make it a violation of `C409` to call `tuple` with a list or set
comprehension, and
implement the (unsafe) fix of calling the `tuple` with the underlying
generator instead.
Closes#12648.
## Test Plan
Test fixture updated, cargo test, docs checked for updated description.
## Summary
Adds autofix for `RUF007`
## Test Plan
`cargo test`, however I get errors for `test resolver::tests::symlink
... FAILED` which seems to not be my fault
## Summary
Fixes#12630.
DOC501 and DOC502 now understand functions with constructs like this to
be explicitly raising `TypeError` (which should be documented in a
function's docstring):
```py
try:
foo():
except TypeError:
...
raise
```
I made an exception for `Exception` and `BaseException`, however.
Constructs like this are reasonably common, and I don't think anybody
would say that it's worth putting in the docstring that it raises "some
kind of generic exception":
```py
try:
foo()
except BaseException:
do_some_logging()
raise
```
## Test Plan
`cargo test -p ruff_linter --lib`
## Summary
Please see
https://github.com/astral-sh/ruff/pull/12605#discussion_r1699957443 for
a description of the issue.
They way I fixed it is to get the *last* timeout item in the `with`, and
if it's an `async with` and there are items after it, then don't trigger
the lint.
## Test Plan
Updated the fixture with some more cases.
