## Summary
This was just a bug in the parser ranges, probably since it was
initially implemented. Given `match n % 3, n % 5: ...`, the "subject"
(i.e., the tuple of two binary operators) was using the entire range of
the `match` statement.
Closes https://github.com/astral-sh/ruff/issues/8091.
## Test Plan
`cargo test`
## Summary
This PR updates our E721 implementation and semantics to match the
updated `pycodestyle` logic, which I think is an improvement.
Specifically, we now allow `type(obj) is int` for exact type
comparisons, which were previously impossible. So now, we're largely
just linting against code like `type(obj) == int`.
This change is gated to preview mode.
Closes https://github.com/astral-sh/ruff/issues/7904.
## Test Plan
Updated the test fixture and ensured parity with latest Flake8.
## Summary
This PR updates our documentation for the upcoming formatter release.
Broadly, the documentation is now structured as follows:
- Overview
- Tutorial
- Installing Ruff
- The Ruff Linter
- Overview
- `ruff check`
- Rule selection
- Error suppression
- Exit codes
- The Ruff Formatter
- Overview
- `ruff format`
- Philosophy
- Configuration
- Format suppression
- Exit codes
- Black compatibility
- Known deviations
- Configuring Ruff
- pyproject.toml
- File discovery
- Configuration discovery
- CLI
- Shell autocompletion
- Preview
- Rules
- Settings
- Integrations
- `pre-commit`
- VS Code
- LSP
- PyCharm
- GitHub Actions
- FAQ
- Contributing
The major changes include:
- Removing the "Usage" section from the docs, and instead folding that
information into "Integrations" and the new Linter and Formatter
sections.
- Breaking up "Configuration" into "Configuring Ruff" (for generic
configuration), and new Linter- and Formatter-specific sections.
- Updating all example configurations to use `[tool.ruff.lint]` and
`[tool.ruff.format]`.
My suggestion is to pull and build the docs locally, and review by
reading them in the browser rather than trying to parse all the code
changes.
Closes https://github.com/astral-sh/ruff/issues/7235.
Closes https://github.com/astral-sh/ruff/issues/7647.
Adds a new `ruff version` sub-command which displays long version
information in the style of `cargo` and `rustc`. We include the number
of commits since the last release tag if its a development build, in the
style of Python's versioneer.
```
❯ ruff version
ruff 0.1.0+14 (947940e91 2023-10-18)
```
```
❯ ruff version --output-format json
{
"version": "0.1.0",
"commit_info": {
"short_commit_hash": "947940e91",
"commit_hash": "947940e91269f20f6b3f8f8c7c63f8e914680e80",
"commit_date": "2023-10-18",
"last_tag": "v0.1.0",
"commits_since_last_tag": 14
}
}%
```
```
❯ cargo version
cargo 1.72.1 (103a7ff2e 2023-08-15)
```
## Test plan
I've tested this manually locally, but want to at least add unit tests
for the message formatting. We'd also want to check the next release to
ensure the information is correct.
I checked build behavior with a detached head and branches.
## Future work
We could include rustc and cargo versions from the build, the current
Python version, and other diagnostic information for bug reports.
The `--version` and `-V` output is unchanged. However, we could update
it to display the long ruff version without the rust and cargo versions
(this is what cargo does). We'll need to be careful to ensure this does
not break downstream packages which parse our version string.
```
❯ ruff --version
ruff 0.1.0
```
The LSP should be updated to use `ruff version --output-format json`
instead of parsing `ruff --version`.
This is my first PR and I'm new at rust, so feel free to ask me to
rewrite everything if needed ;)
The rule must be called after deferred lambas have been visited because
of the last check (whether the lambda parameters are used in the body of
the function that's being called). I didn't know where to do it, so I
did what I could to be able to work on the rule itself:
- added a `ruff_linter::checkers::ast::analyze::lambda` module
- build a vec of visited lambdas in `visit_deferred_lambdas`
- call `analyze::lambda` on the vec after they all have been visited
Building that vec of visited lambdas was necessary so that bindings
could be properly resolved in the case of nested lambdas.
Note that there is an open issue in pylint for some false positives, do
we need to fix that before merging the rule?
https://github.com/pylint-dev/pylint/issues/8192
Also, I did not provide any fixes (yet), maybe we want do avoid merging
new rules without fixes?
## Summary
Checks for lambdas whose body is a function call on the same arguments
as the lambda itself.
### Bad
```python
df.apply(lambda x: str(x))
```
### Good
```python
df.apply(str)
```
## Test Plan
Added unit test and snapshot.
Manually compared pylint and ruff output on pylint's test cases.

## Summary
The lint checks for number of arguments in a function *definition*, but
the message says “function *call*”
## Test Plan
See what breaks and change the tests
Given `print(*a_list_with_elements, sep="\n")`, we can't remove the
separator (unlike in `print(a, sep="\n")`), since we don't know how many
arguments were provided.
Closes https://github.com/astral-sh/ruff/issues/8078.
- Add changelog entry for 0.1.1
- Bump version to 0.1.1
- Require preview for fix added in #7967
- Allow duplicate headings in changelog (markdownlint setting)

## Summary
Fixes https://github.com/astral-sh/ruff/issues/7448
Fixes https://github.com/astral-sh/ruff/issues/7892
I've removed automatic dangling comment formatting, we're doing manual
dangling comment formatting everywhere anyway (the
assert-all-comments-formatted ensures this) and dangling comments would
break the formatting there.
## Test Plan
New test file.

Split out of #8044: In preview style, ellipsis are also collapsed in
non-stub files. This should only affect function/class contexts since
for other statements stub are generally not used. I've updated our tests
to use `pass` instead to reflect this, which makes tracking the preview
style changes much easier.
## Summary
Given an expression like `[x for (x) in y]`, we weren't skipping over
parentheses when searching for the `in` between `(x)` and `y`.
Closes https://github.com/astral-sh/ruff/issues/8053.
