## Summary
This is whitespace as per `is_python_whitespace`, and right now it tends
to lead to panics in the formatter. Seems reasonable to treat it as
whitespace in the `SimpleTokenizer` too.
Closes .https://github.com/astral-sh/ruff/issues/7624.
## Summary
Given:
```python
if True:
if True:
pass
else:
pass
# a
# b
# c
else:
pass
```
We want to preserve the newline after the `# c` (before the `else`).
However, the `last_node` ends at the `pass`, and the comments are
trailing comments on the `pass`, not trailing comments on the
`last_node` (the `if`). As such, when counting the trailing newlines on
the outer `if`, we abort as soon as we see the comment (`# a`).
This PR changes the logic to skip _all_ comments (even those with
newlines between them). This is safe as we know that there are no
"leading" comments on the `else`, so there's no risk of skipping those
accidentally.
Closes https://github.com/astral-sh/ruff/issues/7602.

## Summary
This PR fixes the autofix behavior for `PT022` to create an additional
edit for the return type if it's present. The edit will update the
return type from `Generator[T, ...]` to `T`. As per the [official
documentation](https://docs.python.org/3/library/typing.html?highlight=typing%20generator#typing.Generator),
the first position is the yield type, so we can ignore other positions.
```python
typing.Generator[YieldType, SendType, ReturnType]
```
## Test Plan
Add new test cases, `cargo test` and review the snapshots.
fixes: #7610
## Summary
Implement
[`simplify-print`](https://github.com/dosisod/refurb/blob/master/refurb/checks/builtin/print.py)
as `print-empty-string` (`FURB105`).
Extends the original rule in that it also checks for multiple empty
string positional arguments with an empty string separator.
Related to #1348.
## Test Plan
`cargo test`
Similar to tuples, a generator _can_ be parenthesized or
unparenthesized. Only search for bracketed comments if it contains its
own parentheses.
Closes https://github.com/astral-sh/ruff/issues/7623.
## Summary
Given:
```python
if True:
if True:
if True:
pass
#a
#b
#c
else:
pass
```
When determining the placement of the various comments, we compute the
indentation depth of each comment, and then compare it to the depth of
the previous statement. It turns out this can lead to reordering
comments, e.g., above, `#b` is assigned as a trailing comment of `pass`,
and so gets reordered above `#a`.
This PR modifies the logic such that when we compute the indentation
depth of `#b`, we limit it to at most the indentation depth of `#a`. In
other words, when analyzing comments at the end of branches, we don't
let successive comments go any _deeper_ than their preceding comments.
Closes https://github.com/astral-sh/ruff/issues/7602.

## Summary
Given:
```python
# -*- coding: utf-8 -*-
import random
# Defaults for arguments are defined here
# args.threshold = None;
logger = logging.getLogger("FastProject")
```
We want to count the number of newlines after `import random`, to ensure
that there's _at least one_, but up to two.
Previously, we used the end range of the statement (then skipped
trivia); instead, we need to use the end of the _last comment_. This is
similar to #7556.
Closes https://github.com/astral-sh/ruff/issues/7604.
## Summary
B005 only flags `.strip()` calls for which the argument includes
duplicate characters. This is consistent with bugbear, but isn't
explained in the documentation.
## Summary
Currently, this happens
```sh
$ echo "print()" | ruff format -
#Notice that nothing went to stdout
```
Which does not match `ruff check --fix - ` behavior and deletes my code
every time I format it (more or less 5 times per minute 😄).
I just checked that my example works as the change was very
straightforward.
It is apparently possible to add files to the git index, even if they
are part of the gitignore (see e.g.
https://stackoverflow.com/questions/45400361/why-is-gitignore-not-ignoring-my-files,
even though it's strange that the gitignore entries existed before the
files were added, i wouldn't know how to get them added in that case). I
ran
```
git rm -r --cached .
```
then change the gitignore not actually ignore those files with the
exception of
`crates/ruff_cli/resources/test/fixtures/cache_mutable/source.py`, which
is actually a generated file.
## Summary
This is only used for the `level` field in relative imports (e.g., `from
..foo import bar`). It seems unnecessary to use a wrapper here, so this
PR changes to a `u32` directly.
## Summary
When we format the trailing comments on a clause body, we check if there
are any newlines after the last statement; if not, we insert one.
This logic didn't take into account that the last statement could itself
have trailing comments, as in:
```python
if True:
pass
# comment
else:
pass
```
We were thus inserting a newline after the comment, like:
```python
if True:
pass
# comment
else:
pass
```
In the context of function definitions, this led to an instability,
since we insert a newline _after_ a function, which would in turn lead
to the bug above appearing in the second formatting pass.
Closes https://github.com/astral-sh/ruff/issues/7465.
## Test Plan
`cargo test`
Small improvement in `transformers`, but no regressions.

This PR updates the flake8-self license from Freely Distributable to the
MIT License to match the upstream license, which was recently updated.

## Summary
If a function has no parameters (and no comments within the parameters'
`()`), we're supposed to wrap the return annotation _whenever_ it
breaks. However, our `empty_parameters` test didn't properly account for
the case in which the parameters include a newline (but no other
content), like:
```python
def get_dashboards_hierarchy(
) -> Dict[Type['BaseDashboard'], List[Type['BaseDashboard']]]:
"""Get hierarchy of dashboards classes.
Returns:
Dict of dashboards classes.
"""
dashboards_hierarchy = {}
```
This PR fixes that detection. Instead of lexing, it now checks if the
parameters itself is empty (or if it contains comments).
Closes https://github.com/astral-sh/ruff/issues/7457.
## Summary
## Stack Summary
This stack splits `Settings` into `FormatterSettings` and `LinterSettings` and moves it into `ruff_workspace`. This change is necessary to add the `FormatterSettings` to `Settings` without adding `ruff_python_formatter` as a dependency to `ruff_linter` (and the linter should not contain the formatter settings).
A quick overview of our settings struct at play:
* `Options`: 1:1 representation of the options in the `pyproject.toml` or `ruff.toml`. Used for deserialization.
* `Configuration`: Resolved `Options`, potentially merged from multiple configurations (when using `extend`). The representation is very close if not identical to the `Options`.
* `Settings`: The resolved configuration that uses a data format optimized for reading. Optional fields are initialized with their default values. Initialized by `Configuration::into_settings` .
The goal of this stack is to split `Settings` into tool-specific resolved `Settings` that are independent of each other. This comes at the advantage that the individual crates don't need to know anything about the other tools. The downside is that information gets duplicated between `Settings`. Right now the duplication is minimal (`line-length`, `tab-width`) but we may need to come up with a solution if more expensive data needs sharing.
This stack focuses on `Settings`. Splitting `Configuration` into some smaller structs is something I'll follow up on later.
## PR Summary
This PR moves the `ResolverSettings` and `Settings` struct to `ruff_workspace`. `LinterSettings` remains in `ruff_linter` because it gets passed to lint rules, the `Checker` etc.
