## Summary
This PR adds a new `cell` field to the JSON output format which
indicates the Notebook cell this diagnostic (and fix) belongs to. It
also updates the location for the diagnostic and fixes as per the
`NotebookIndex`. It will be used in the VSCode extension to display the
diagnostic in the correct cell.
The diagnostic and edit start and end source locations are translated
for the notebook as per the `NotebookIndex`. The end source location for
an edit needs some special handling.
### Edit end location
To understand this, the following context is required:
1. Visible lines in Jupyter Notebook vs JSON array strings: The newline
is part of the string in the JSON format. This means that if there are 3
visible lines in a cell where the last line is empty then the JSON would
contain 2 strings in the source array, both ending with a newline:
**JSON format:**
```json
[
"# first line\n",
"# second line\n",
]
```
**Notebook view:**
```python
1 # first line
2 # second line
3
```
2. If an edit needs to remove an entire line including the newline, then
the end location would be the start of the next row.
To remove a statement in the following code:
```python
import os
```
The edit would be:
```
start: row 1, col 1
end: row 2, col 1
```
Now, here's where the problem lies. The notebook index doesn't have any
information for row 2 because it doesn't exists in the actual notebook.
The newline was added by Ruff to concatenate the source code and it's
removed before writing back. But, the edit is computed looking at that
newline.
This means that while translating the end location for an edit belong to
a Notebook, we need to check if both the start and end location belongs
to the same cell. If not, then the end location should be the first
character of the next row and if so, translate that back to the last
character of the previous row. Taking the above example, the translated
location for Notebook would be:
```
start: row 1, col 1
end: row 1, col 10
```
## Test Plan
Add test cases for notebook output in the JSON format and update
existing snapshots.
## Summary
This PR refactors the `NotebookIndex` struct to use `OneIndexed` to make
the
intent of the code clearer.
## Test Plan
Update the existing test case and run `cargo test` to verify the change.
- [x] Verify `--diff` output
- [x] Verify the diagnostics output
- [x] Verify `--show-source` output
**Summary** Handle comment before the default values of function
parameters correctly by inserting a line break instead of space after
the equals sign where required.
```python
def f(
a = # parameter trailing comment; needs line break
1,
b =
# default leading comment; needs line break
2,
c = ( # the default leading can only be end-of-line with parentheses; no line break
3
),
d = (
# own line leading comment with parentheses; no line break
4
)
)
```
Fixes#7603
**Test Plan** Added the different cases and one more complex case as
fixtures.
## Summary
This PR fixes the bug where the rule `E251` was being triggered on a equal token
inside a f-string which was used in the context of debug expressions.
For example, the following was being flagged before the fix:
```python
print(f"{foo = }")
```
But, now it is not. This leads to false negatives such as:
```python
print(f"{foo(a = 1)}")
```
One solution would be to know if the opened parentheses was inside a f-string or
not. If it was then we can continue flagging until it's closed. If not, then we
should not flag it.
## Test Plan
Add new test cases and check that they don't raise any false positives.
fixes: #7882
## Summary
`foo(**{})` was an overlooked edge case for `PIE804` which introduced a
crash within the Fix, introduced in #7884.
I've made it so that `foo(**{})` turns into `foo()` when applied with
`--fix`, but is that desired/expected? 🤔 Should we just ignore instead?
## Test Plan
`cargo test`
Closes https://github.com/astral-sh/ruff/issues/7572
Drops formatting specific rules from the default rule set as they
conflict with formatters in general (and in particular, conflict with
our formatter). Most of these rules are in preview, but the removal of
`line-too-long` and `mixed-spaces-and-tabs` is a change to the stable
rule set.
## Example
The following no longer raises `E501`
```
echo "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx = 1" | ruff check -
```
## Summary
Throughout the codebase, we have this pattern:
```rust
let mut diagnostic = ...
if checker.patch(Rule::UnusedVariable) {
// Do the fix.
}
diagnostics.push(diagnostic)
```
This was helpful when we computed fixes lazily; however, we now compute
fixes eagerly, and this is _only_ used to ensure that we don't generate
fixes for rules marked as unfixable.
We often forget to add this, and it leads to bugs in enforcing
`--unfixable`.
This PR instead removes all of these checks, moving the responsibility
of enforcing `--unfixable` up to `check_path`. This is similar to how
@zanieb handled the `--extend-unsafe` logic: we post-process the
diagnostics to remove any fixes that should be ignored.
## Summary
Add autofix for `PLR1714` using tuples.
If added complexity is desired, we can lean into the `set` part by doing
some kind of builtin check on all of the comparator elements for
starters, since we otherwise don't know if something's hashable.
## Test Plan
`cargo test`, and manually.
**Summary** Remove spaces from import statements such as
```python
import tqdm . tqdm
from tqdm . auto import tqdm
```
See also #7760 for a better solution.
**Test Plan** New fixtures
**Summary** Quoting of f-strings can change if they are triple quoted
and only contain single quotes inside.
Fixes#6841
**Test Plan** New fixtures

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
closes https://github.com/astral-sh/ruff/issues/7912
## Test Plan
<!-- How was it tested? -->
Adds two configuration-file only settings `extend-safe-fixes` and
`extend-unsafe-fixes` which can be used to promote and demote the
applicability of fixes for rules.
Fixes with `Never` applicability cannot be promoted.
## Summary
This fixes the theme toggle so it has the most useful setting on by
default: following the system dark/light mode
See
https://squidfunk.github.io/mkdocs-material/setup/changing-the-colors/#automatic-light-dark-mode
## Test Plan
It follows the official docs exactly. If the docs get published for each
PR branch, we can also check there if it works as intended.

## Summary
Given:
```python
baz: Annotated[
str,
[qux for qux in foo],
]
```
We treat `baz` as `BindingKind::Annotation`, to ensure that references
to `baz` are marked as unbound. However, we were _also_ treating `qux`
as `BindingKind::Annotation`, which meant that the load in the
comprehension _also_ errored.
Closes https://github.com/astral-sh/ruff/issues/7879.
## Summary
This PR upgrades some rules from "sometimes" to "always" fixes, now that
we're getting ready to ship support in the CLI. The focus here was on
identifying rules for which the diagnostic itself is high-confidence,
and the fix itself is too (assuming that the diagnostic is correct).
This is _unlike_ rules that _may_ be a false positive, like those that
(e.g.) assume an object is a dictionary when you call `.values()` on it.
Specifically, I upgraded:
- A bunch of rules that only apply to `.pyi` files.
- Rules that rewrite deprecated imports or aliases.
- Some other misc. rules, like: `empty-print-string`, `unused-noqa`,
`getattr-with-constant`.
Open to feedback on any of these.
## Summary
Adds autofix to `PYI030`
Closes#7854.
Unsure if the cloning method I chose is the best solution here, feel
free to suggest alternatives!
## Test Plan
`cargo test` as well as manually
## Summary
Restores functionality of #7875 but in the correct place. Closes#7877.
~~I couldn't figure out how to get cargo fmt to work, so hopefully
that's run in CI.~~ Nevermind, figured it out.
## Test Plan
Can see output of json.
