## Summary
This PR adds some snapshot tests for the resolver based on executing
resolutions within a "mock" of the Airflow repo (that is: a folder that
contains a subset of the repo's files, but all empty, and with an
only-partially-complete virtual environment). It's intended to act as a
lightweight integration test, to enable us to test resolutions on a
"real" project without adding a dependency on Airflow itself.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Currently the URL at the bottom of the `ruff rule SLOT00x` output points
to Python 3.7 docs.
Given that Python 3.7 is now end-of-life (as of yesterday), let's
instead point users to the current Python docs.
## Test Plan
<!-- How was it tested? -->
## Summary
Consider Jupyter index for code frames (`--show-source`).
This solves two problems as mentioned in the linked issue:
> Omit any contents from adjoining cells
If the Jupyter index is present, we'll use that to check if the
surrounding
lines belong to the same cell as the content line. If not, we'll skip
that line
until we either reach the one which does or we reach the content line.
> code frame line number
If the Jupyter index is present, we'll use that to get the actual start
line in
corresponding to the computed start index.
## Test Plan
`cargo run --bin ruff -- check --no-cache --isolated --select=ALL --show-source /path/to/notebook.ipynb`
fixes: #5395
## Summary
Add Jupyter integration to the docs, specifically the Configuration and
FAQ sections.
## Test Plan
`mkdocs serve` and check that the new sections are visible and
functional.
fixes: #5396
## Summary
The `Y053` rule of `flake8-pyi` ignores docstrings, it only triggers on
other string literals.
The separate `Y021/PYI021` rule exists to disallow docstrings.
## Test Plan
Added some `# OK` test cases to `PYI053.py(i)` files.
## Summary
Implement Pylint rule `single-string-used-for-slots` (`C0205`) as
`single-string-slots` (`PLC0205`). This rule checks for single strings
being assigned to `__slots__`. For example
```python
class Foo:
__slots__: str = "bar"
def __init__(self, bar: str) -> None:
self.bar = bar
```
should be
```python
class Foo:
__slots__: tuple[str, ...] = ("bar",)
def __init__(self, bar: str) -> None:
self.bar = bar
```
Related to #970. Includes documentation.
## Test Plan
`cargo test`
## Summary
Replace same length equal line with dash line in D407
Do we want to update the message and autofix title to reflect this
change?
## Test Plan
Added test cases for:
- Equal line length == dash line length
- Equal line length != dash line length
fixes: #5378
## Summary
This PR contains the first step towards enabling robust first-party,
third-party, and standard library import resolution in Ruff (including
support for `typeshed`, stub files, native modules, etc.) by porting
Pyright's import resolver to Rust.
The strategy taken here was to start with a more-or-less direct port of
the Pyright's TypeScript resolver. The code is intentionally similar,
and the test suite is effectively a superset of Pyright's test suite for
its own resolver. Due to the nature of the port, the code is very, very
non-idiomatic for Rust. The code is also entirely unused outside of the
test suite, and no effort has been made to integrate it with the rest of
the codebase.
Future work will include:
- Refactoring the code (now that it works) to match Rust and Ruff
idioms.
- Further testing, in practice, to ensure that the resolver can resolve
imports in a complex project, when provided with a virtual environment
path.
- Caching, to minimize filesystem lookups and redundant resolutions.
- Integration into Ruff itself (use Ruff's existing settings, find rules
that can make use of robust resolution, etc.)
ruff_dev repeat recently broke (i think with the cargo update?):
> thread 'main' panicked at 'Command repeat: Short option names must be
unique for each argument, but '-n' is in use by both 'no_cache' and
'repeat''
This fixes this by removing the short argument.
## Summary
This formats call expressions with magic trailing comma and parentheses
behaviour but without call chaining
## Test Plan
Lots of new test fixtures, including some that don't work yet
## Summary
Implements PERF203 from #4789, which throws if a `try/except` block is
inside of a loop. Not sure if we want to extend the diagnostic to the
`except` as well, but I thought that that may get a little messy. We may
also want to just throw on the word `try` - open to suggestions though.
## Test Plan
`cargo test`
## Summary
These had just bitrotted over time -- we were no longer passing along
the row-and-column indices, etc.
## Test Plan
## Summary
`v0.0.275` in the top-right was showing `v0.0.0` at all times.
## Test Plan
## Summary
Experimental release for Jupyter Notebook integration.
Currently, this requires a user to explicitly opt-in using the
[include](https://beta.ruff.rs/docs/settings/#include) configuration:
```toml
[tool.ruff]
include = ["*.py", "*.pyi", "**/pyproject.toml", "*.ipynb"]
```
Or, a user can pass in the file directly:
```sh
ruff check path/to/notebook.ipynb
```
For known limitations, please refer #5188
## Test Plan
Following command should work without the `--all-features` flag:
```sh
cargo dev round-trip /path/to/notebook.ipynb
```
Following command should work with the above config file along with
`select = ["ALL"]`:
```sh
cargo run --bin ruff -- check --no-cache --config=../test-repos/openai-cookbook/pyproject.toml --fix ../test-repos/openai-cookbook/
```
Passing the Jupyter notebook directly:
```sh
cargo run --bin ruff -- check --no-cache --isolated --select=ALL --fix ../test-repos/openai-cookbook/examples/Classification_using_embeddings.ipynb
```
## Summary
Add documentation to the `D1XX` rules that flag missing docstrings.
The examples are quite long and docstrings practices vary a lot between
projects, so I thought it would be best that the documentation for these
rules be their own PR separate to the other `pydocstyle` rules.
Related to #2646.
## Test Plan
`python scripts/check_docs_formatted.py`

## Summary
This PR extends the string formatting to respect the configured quote style.
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
Extended the string test with new cases and set it up to run twice: Once with the `quote_style: Doube`, and once with `quote_style: Single` single and double quotes.

## Summary
This PR adds tests that verify that the magic trailing comma is not respected if disabled in the formatter options.
Our test setup now allows to create a `<fixture-name>.options.json` file that contains an array of configurations that should be tested.
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
It's all about tests :)

## Summary
This PR adds a new `PyFormatOptions` struct that stores the python formatter options.
The new options aren't used yet, with the exception of magical trailing commas and the options passed to the printer.
I'll follow up with more PRs that use the new options (e.g. `QuoteStyle`).
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
`cargo test` I'll follow up with a new PR that adds support for overriding the options in our fixture tests.
## Motation
Previously,
```python
x = (
a1
.a2
# a
. # b
# c
a3
)
```
got formatted as
```python
x = a1.a2
# a
. # b
# c
a3
```
which is invalid syntax. This fixes that.
## Summary
This implements a basic form of attribute chaining
(<https://black.readthedocs.io/en/stable/the_black_code_style/current_style.html#call-chains>)
by checking if any inner attribute access contains an own line comment,
and if this is the case, adds parentheses around the outermost attribute
access while disabling parentheses for all inner attribute expressions.
We want to replace this with an implementation that uses recursion or a
stack while formatting instead of in `needs_parentheses` and also
includes calls rather sooner than later, but i'm fixing this now because
i'm uncomfortable with having known invalid syntax generation in the
formatter.
## Test Plan
I added new fixtures.
## Summary
Add documentation to the `D3XX` rules that check for issues with
docstring quotes. Related to #2646.
## Test Plan
`python scripts/check_docs_formatted.py`
## Summary
Ignore type aliases for RUF013 to avoid flagging false positives:
```python
from typing import Optional
MaybeInt = Optional[int]
def f(arg: MaybeInt = None):
pass
```
But, at the expense of having false negatives:
```python
Text = str | bytes
def f(arg: Text = None):
pass
```
## Test Plan
`cargo test`
fixes: #5295
