## Summary
This PR adds VS Code specific extension settings in the online
documentation.
The content is basically taken from the `package.json` file in the
`ruff-vscode` repository.
## Summary
Following the stabilization of the Ruff language server, we need to
update our versioning policy to account for any changes in it. This
could be server settings, capability, etc.
This PR also adds a new section for the VS Code extension which is
adopted from [Biome's versioning
policy](https://biomejs.dev/internals/versioning/#visual-studio-code-extension)
for the same.

## Summary
This PR adds documentation for the Ruff language server.
It mainly does the following:
1. Combines various READMEs containing instructions for different editor
setup in their respective section on the online docs
2. Provide an enumerated list of server settings. Additionally, it also
provides a section for VS Code specific options.
3. Adds a "Features" section which enumerates all the current
capabilities of the native server
For (2), the settings documentation is done manually but a future
improvement (easier after `ruff-lsp` is deprecated) is to move the docs
in to Rust struct and generate the documentation from the code itself.
And, the VS Code extension specific options can be generated by diffing
against the `package.json` in `ruff-vscode` repository.
### Structure
1. Setup: This section contains the configuration for setting up the
language server for different editors
2. Features: This section contains a list of capabilities provided by
the server along with short GIF to showcase it
3. Settings: This section contains an enumerated list of settings in a
similar format to the one for the linter / formatter
4. Migrating from `ruff-lsp`
> [!NOTE]
>
> The settings page is manually written but could possibly be
auto-generated via a macro similar to `OptionsMetadata` on the
`ClientSettings` struct
resolves: #11217
## Test Plan
Generate and open the documentation locally using:
1. `python scripts/generate_mkdocs.py`
2. `mkdocs serve -f mkdocs.insiders.yml`
## Summary
In order to use single quotes with both the ruff linter and the ruff
formatter,
two different rules must be applied. This was not clear to me when
internet searching "configure ruff single quotes" and it eventually
I filed this issue:
https://github.com/astral-sh/ruff/issues/12003
Tested on Fedora 40 with Podman 5.1.1 and ruff "0.5.0" and "latest".

## Summary
Implement support for RDJson output for `ruff check`, as requested in
#8655.
## Test Plan
Tested using a snapshot test. Same approach as for e.g. the JSON output
formatter.
## Additional info
I tried to keep the implementation close to the JSON implementation.
I had to deviate a bit to make the `suggestions` key work: If there are
no suggestions, then setting `suggestions` to `null` is invalid
according to the JSONSchema. Therefore, I opted for a slightly more
complex implementation, that skips the `suggestions` key entirely if
there are no fixes available for the given diagnostic. Maybe it would
have been easier to set `"suggestions": []`, but I ended up doing it
this way.
I didn't consider notebooks, as I _think_ that RDJson doesn't work with
notebooks. This should be confirmed, and if so, there should be some
form of warning or error emitted when trying to output diagnostics for a
notebook.
I also didn't consider `ruff format`, as this comment:
https://github.com/astral-sh/ruff/issues/8655#issuecomment-1811446160
suggests that that wouldn't be compatible.
I'm new to Rust, any feedback is appreciated. 🙂 I
implemented this in order to have a productive rainy saturday afternoon,
I'm not knowledgeable about RDJson beyond the sources linked in the
issue.
## Summary
I've added support for configuring the `ruff check` output file via the
environment variable `RUFF_OUTPUT_FILE` akin to #1731.
This is super useful when, e.g., generating a [GitLab code quality
report](https://docs.gitlab.com/ee/ci/testing/code_quality.html#implement-a-custom-tool)
while running Ruff as a pre-commit hook. Usually, `ruff check` should
print its human-readable output to `stdout`, but when run through
`pre-commit` _in a GitLab CI job_ it should write its output in `gitlab`
format to a file. So, to override these two settings only during CI,
environment variables come handy, and `RUFF_OUTPUT_FORMAT` already
exists but `RUFF_OUTPUT_FILE` has been missing.
A (simplified) GitLab CI job config for this scenario might look like
this:
```yaml
pre-commit:
stage: test
image: python
variables:
RUFF_OUTPUT_FILE: gl-code-quality-report.json
RUFF_OUTPUT_FORMAT: gitlab
before_script:
- pip install pre-commit
script:
- pre-commit run --all-files --show-diff-on-failure
artifacts:
reports:
codequality: gl-code-quality-report.json
```
## Test Plan
I tested it manually.
Fixes#5499
## Summary
Add support for `FORCE_COLOR` env var, as specified at
https://force-color.org/
## Test Plan
I wrote an integration test for this, and then realized that can't work,
since we use a dev-dependency on `colored` with the `no-color` feature
to avoid ANSI color codes in test snapshots.
So this is just tested manually.
`cargo run --features test-rules -- check --no-cache --isolated -
--select RUF901 --diff < /dev/null` shows a colored diff.
`cargo run --features test-rules -- check --no-cache --isolated -
--select RUF901 --diff < /dev/null | less` does not have color, since we
pipe it to `less`.
`FORCE_COLOR=1 cargo run --features test-rules -- check --no-cache
--isolated - --select RUF901 --diff < /dev/null | less` does have color
(after this diff), even though we pipe it to `less`.
Section about comparing Ruff to PyLint now is more precise about the
following two points:
- Ruff do count branches different and there for earlier give
too-many-branches warning.
- Activating all Pylint rules in Ruff also activates pylint rules that
are not active by default in Pylint itself because they are implemented
via pylint plugins.
## Summary
Since #10217 the [formatter
docs](https://docs.astral.sh/ruff/formatter/) contained
```
ruff format # Format all files in the current directory.
ruff format path/to/code/ # Lint all files in `path/to/code` (and any subdirectories).
ruff format path/to/file.py # Format a single file.
```
I believe the `Lint` here is a copy-paste typo from the [linter
docs](https://docs.astral.sh/ruff/linter/).
## Test Plan
N/A
## Summary
The purpose of this change is mainly to address one of the issues
outlined in #10427. Namely, some lists in the docs were not rendering
properly when preceded by a text block without a newline character. This
PR adds `mdformat` as a final step to the rule documentation script, so
that any missing newlines will be added.
NB: The default behavior of `mdformat` is to escape markdown special
characters found in text such as `<`. This resulted in some misformatted
docs. To address this I implemented an ad-hoc mdformat plugin to
override the behavior. This may be considered a bit 'hacky', but I think
it's a good solution. Nevertheless, if someone has a better idea, let me
know.
## Test Plan
This change is hard to test systematically, however, I tried my best to
look at the before and after diffs to ensure no unwanted changes were
made to the docs.
## Summary
#10151 documented the deviations between Ruff and Black with the new
2024 style guide in the `ruff-python-formatter/README.md`. However,
that's not the documentation shown
on the website when navigating to [intentional
deviations](https://docs.astral.sh/ruff/formatter/black/).
This PR streamlines the `ruff-python-formatter/README.md` and links to
the documentation on the website instead of repeating the same content.
The PR also makes the 2024 style guide deviations available on the
website documentation.
## Test Plan
I built the documentation locally and verified that the 2024 style guide
known deviations are now shown on the website.
## Summary
This PR modifies the documentation to use `ruff check` instead of `ruff
check .`, and `ruff format` instead of `ruff format .`, as discussed
[here](https://github.com/astral-sh/ruff/pull/10168#discussion_r1509976904)

I used `codespell` and `gramma` to identify mispellings and grammar
errors throughout the codebase and fixed them. I tried not to make any
controversial changes, but feel free to revert as you see fit.

## Summary
This PR introduces the `ruff_server` crate and a new `ruff server`
command. `ruff_server` is a re-implementation of
[`ruff-lsp`](https://github.com/astral-sh/ruff-lsp), written entirely in
Rust. It brings significant performance improvements, much tighter
integration with Ruff, a foundation for supporting entirely new language
server features, and more!
This PR is an early version of `ruff_lsp` that we're calling the
**pre-release** version. Anyone is more than welcome to use it and
submit bug reports for any issues they encounter - we'll have some
documentation on how to set it up with a few common editors, and we'll
also provide a pre-release VSCode extension for those interested.
This pre-release version supports:
- **Diagnostics for `.py` files**
- **Quick fixes**
- **Full-file formatting**
- **Range formatting**
- **Multiple workspace folders**
- **Automatic linter/formatter configuration** - taken from any
`pyproject.toml` files in the workspace.
Many thanks to @MichaReiser for his [proof-of-concept
work](https://github.com/astral-sh/ruff/pull/7262), which was important
groundwork for making this PR possible.
## Architectural Decisions
I've made an executive choice to go with `lsp-server` as a base
framework for the LSP, in favor of `tower-lsp`. There were several
reasons for this:
1. I would like to avoid `async` in our implementation. LSPs are mostly
computationally bound rather than I/O bound, and `async` adds a lot of
complexity to the API, while also making harder to reason about
execution order. This leads into the second reason, which is...
2. Any handlers that mutate state should be blocking and run in the
event loop, and the state should be lock-free. This is the approach that
`rust-analyzer` uses (also with the `lsp-server`/`lsp-types` crates as a
framework), and it gives us assurances about data mutation and execution
order. `tower-lsp` doesn't support this, which has caused some
[issues](https://github.com/ebkalderon/tower-lsp/issues/284) around data
races and out-of-order handler execution.
3. In general, I think it makes sense to have tight control over
scheduling and the specifics of our implementation, in exchange for a
slightly higher up-front cost of writing it ourselves. We'll be able to
fine-tune it to our needs and support future LSP features without
depending on an upstream maintainer.
## Test Plan
The pre-release of `ruff_server` will have snapshot tests for common
document editing scenarios. An expanded test suite is on the roadmap for
future version of `ruff_server`.
## Summary
This PR was prompted by the discussion in #10153.
It adds CLI tab examples next to the `pyproject.toml` and `ruff.toml`
examples. It should be helpful for users wanting to try out the preview
mode without modifying or creating a `.toml` file.
It also adds a paragraph to try to make the effect of the preview mode
less confusing.
Fixes#8368
Fixes https://github.com/astral-sh/ruff/issues/9186
## Summary
Arbitrary TOML strings can be provided via the command-line to override
configuration options in `pyproject.toml` or `ruff.toml`. As an example:
to run over typeshed and respect typeshed's `pyproject.toml`, but
override a specific isort setting and enable an additional pep8-naming
setting:
```
cargo run -- check ../typeshed --no-cache --config ../typeshed/pyproject.toml --config "lint.isort.combine-as-imports=false" --config "lint.extend-select=['N801']"
```

Adds a new `Deprecated` rule group in addition to `Stable` and
`Preview`.
Deprecated rules:
- Warn on explicit selection without preview
- Error on explicit selection with preview
- Are excluded when selected by prefix with preview
Deprecates `TRY200`, `ANN101`, and `ANN102` as a proof of concept. We
can consider deprecating them separately.
Extends #9682 to error if the nursery selector is used or nursery rules
are selected without preview.
Part of #7992 — we will remove this in 0.3.0 instead so we can provide
nice errors in 0.2.0.

Fixes#7350
## Summary
* `--show-source` and `--no-show-source` are now deprecated.
* `output-format` supports two new variants, `full` and `concise`.
`text` is now a deprecated variant, and any use of it is treated as the
default serialization format.
* `--output-format` now default to `concise`
* In preview mode, `--output-format` defaults to `full`
* `--show-source` will still set `--output-format` to `full` if the
output format is not otherwise specified.
* likewise, `--no-show-source` can override an output format that was
set in a file-based configuration, though it will also be overridden by
`--output-format`
## Test Plan
A lot of tests were updated to use `--output-format=full`. Additional
tests were added to ensure the correct deprecation warnings appeared,
and that deprecated options behaved as intended.

Previously, without the 'wrap_help' feature enabled, Clap would not do
any auto-wrapping of help text. For help text with long lines, this
tends to lead to non-ideal formatting. It can be especially difficult to
read when the width of the terminal is smaller.
This commit enables 'wrap_help', which will automatically cause Clap to
query the terminal size and wrap according to that. Or, if the terminal
size cannot be determined, it will default to a maximum line width of
100.

## Summary
For emacs users just seeking a ruff formatter, apheleia is overkill.
Instead, a melpa package
[emacs-ruff-format](https://github.com/scop/emacs-ruff-format) exists
now.
This change prepends a mention of this package, without removing
apheleia as an alternative.
## Test Plan
This is how I integrated ruff into my emacs.

This PR does the plumbing to make a new formatting option,
`docstring-code-format`, available in the configuration for end users.
It is disabled by default (opt-in). It is opt-in at least initially to
reflect a conservative posture. The intent is to make it opt-out at some
point in the future.
This was split out from #8811 in order to make #8811 easier to merge.
Namely, once this is merged, docstring code snippet formatting will
become available to end users. (See comments below for how we arrived at
the name.)
Closes#7146
## Test Plan
Other than the standard test suite, I ran the formatter over the CPython
and polars projects to ensure both that the result looked sensible and
that tests still passed. At time of writing, one issue that currently
appears is that reformatting code snippets trips the long line lint:
https://github.com/BurntSushi/polars/actions/runs/7006619426/job/19058868021
## Summary
Adds support for sarif v2.1.0 output to cli, usable via the
output-format paramter.
`ruff . --output-format=sarif`
Includes a few changes I wasn't sure of, namely:
* Adds a few derives for Clone & Copy, which I think could be removed
with a little extra work as well.
## Test Plan
I built and ran this against several large open source projects and
verified that the output sarif was valid, using [Microsoft's SARIF
validator tool](https://sarifweb.azurewebsites.net/Validation)
I've also attached an output of the sarif generated by this version of
ruff on the main branch of django at commit: b287af5dc9
[django_main_b287af5dc9_sarif.json](https://github.com/astral-sh/ruff/files/13626222/django_main_b287af5dc9_sarif.json)
Note: this needs to be regenerated with the latest changes and
confirmed.
## Open Points
[ ] Convert to just using all Rules all the time
[ ] Fix the issue with getting the file URI when compiling for web
assembly
Hides hints about unsafe fixes when they are disabled e.g. with
`--no-unsafe-fixes` or `unsafe-fixes = false`. By default, unsafe fix
hints are still displayed. This seems like a nice way to remove the nag
for users who have chosen not to apply unsafe fixes.

## Summary
This PR adds the command to run ruff using [pkgx](https://pkgx.sh).
<!-- What's the purpose of the change? What does it do, and why? -->
It's just showing that ruff is supported in one more package manager.
## Test Plan
You can run `pkgx ruff` if you have pkgx installed or run `sh <(curl
https://pkgx.sh) +github.com/charliermarsh/ruff sh
`
Closes https://github.com/astral-sh/ruff/issues/7347Closes#3970 via use of `include`
We could update examples in our documentation, but I worry since we do
not have versioned documentation users on older versions would be
confused. Instead, I'll open an issue to track updating use of `ruff
check .` in the documentation sometime in the future.

## Summary
This adds redirects from, e.g., `https://docs.astral.sh/ruff/rules/F401`
to `https://docs.astral.sh/ruff/rules/unused-import`, which are
generated automatically when creating the documentation. Though we want
to move towards human-readable names eventually, I think this is a nice
and user-friendly change (and doesn't require any fancy infrastructure,
since the redirects are handled via a plugin and added client-side).
Closes#4710.
## Summary
The ruff configuration section is called "format", rather than
"preview". Using the configuration as it was written in the docs gives
an error:
```
$ ruff format --check .
ruff failed
Cause: TOML parse error at line 143, column 1
|
143 | [tool.ruff.preview]
| ^^^^^^^^^^^^^^^^^^^
invalid type: map, expected a boolean
```
## Test Plan
Tested running `ruff format` with the following in my `pyproject.toml`:
```toml
[tool.ruff.format]
preview = true
```
and it worked properly (using preview rules for formatting).
This ensures the python label is used for all python code blocks for
consistency.
## Test Plan
Visual inspection of all changes via git client ensuring no other
changes were made in error.
I got some feedback on Mastodon that it wasn't clear how to use the
linter and formatter together in pre-commit (mostly in the pre-commit
repo's documentation, which is even less clear, but the two should be
consistent).
## Summary
Being able to set `--no-cache` without touching the command line makes
comparing formatter speed with e.g. Hyperfine a lot easier; Black allows
one to set `BLACK_CACHE_DIR=/dev/null`, but setting
`RUFF_CACHE_DIR=/dev/null` has Ruff choke:
```
error: Failed to initialize cache at /dev/null: Not a directory (os error 20)
error: Failed to initialize cache at /dev/null: Not a directory (os error 20)
warning: Failed to open cache file '/dev/null/0.1.4/18160934645386409287': Not a directory (os error 20)
```
Alternately, we could make a `/dev/null` (or `nul` on Windows) cache
directory imply `--no-cache`?
## Test Plan
None yet.
## Summary
Similarly to https://github.com/astral-sh/ruff/pull/8302, the
configuration documentation mentions `extend-exclude` for tool specific
configuration, although neither `format` nor `lint` supports it, since
they only support `exclude`.

<!-- How was it tested? -->
**Summary** Prepare for the black preview style becoming the black
stable style at the end of the year.
This adds a new test file to compare stable and preview on some relevant
preview options in black, and makes `format_dev` understand the black
preview flag. I've added poetry as a project that uses preview.
I've implemented one specific deviation (collapsing of stub
implementation in non-stub files) which showed up in poetry for testing.
This also improves poetry compatibility from 0.99891 to 0.99919.

<!-- How was it tested? -->
## Summary
The previous configuration for `ruff` contained an unrecognized field
`magic-trailing-comma` set to "respect". As of version 0.1.2 of `ruff`,
this field was not recognized and resulted in a TOML parse error when
running the `ruff format .` command. This change removes the
`magic-trailing-comma` field and adds the recognized
`skip-magic-trailing-comma` field set to `false`.
## Test Plan
Tested locally with `ruff` 0.1.2.
Per some previous discussion, the policy is not clear about what happens
if the behavior is similar but the _scope_ in which a rule is applied
changes.
## 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.

❯ 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`.
- 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
We don't enable E501 by default, but `line-length` is a useful example
for configuration, so we now set `--extend-select` in the tutorial with
a note to that effect.
I've also updated all the outputs to match the latest CLI behavior, and
changed the example from `List` to `Sequence` because `List` now spits
out two diagnostics (one for the import, one for the usage), which IMO
is confusing for beginners.
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 -
```
Rebase of https://github.com/astral-sh/ruff/pull/5119 authored by
@evanrittenhouse with additional refinements.
## Changes
- Adds `--unsafe-fixes` / `--no-unsafe-fixes` flags to `ruff check`
- Violations with unsafe fixes are not shown as fixable unless opted-in
- Fix applicability is respected now
- `Applicability::Never` fixes are no longer applied
- `Applicability::Sometimes` fixes require opt-in
- `Applicability::Always` fixes are unchanged
- Hints for availability of `--unsafe-fixes` added to `ruff check`
output
## Examples
Check hints at hidden unsafe fixes
```
❯ ruff check example.py --no-cache --select F601,W292
example.py:1:14: F601 Dictionary key literal `'a'` repeated
example.py:2:15: W292 [*] No newline at end of file
Found 2 errors.
[*] 1 fixable with the `--fix` option (1 hidden fix can be enabled with the `--unsafe-fixes` option).
```
We could add an indicator for which violations have hidden fixes in the
future.
Check treats unsafe fixes as applicable with opt-in
```
❯ ruff check example.py --no-cache --select F601,W292 --unsafe-fixes
example.py:1:14: F601 [*] Dictionary key literal `'a'` repeated
example.py:2:15: W292 [*] No newline at end of file
Found 2 errors.
[*] 2 fixable with the --fix option.
```
Also can be enabled in the config file
```
❯ cat ruff.toml
unsafe-fixes = true
```
And opted-out per invocation
```
❯ ruff check example.py --no-cache --select F601,W292 --no-unsafe-fixes
example.py:1:14: F601 Dictionary key literal `'a'` repeated
example.py:2:15: W292 [*] No newline at end of file
Found 2 errors.
[*] 1 fixable with the `--fix` option (1 hidden fix can be enabled with the `--unsafe-fixes` option).
```
Diff does not include unsafe fixes
```
❯ ruff check example.py --no-cache --select F601,W292 --diff
--- example.py
+++ example.py
@@ -1,2 +1,2 @@
x = {'a': 1, 'a': 1}

https://github.com/astral-sh/ruff/pull/7790 will improve the diff
messages following this pull request
Similarly, `--fix` and `--fix-only` require the `--unsafe-fixes` flag to
apply unsafe fixes.

Closes#7434
Replaces the `PREVIEW` selector (removed in #7389) with a configuration
option `explicit-preview-rules` which requires selectors to use exact
rule codes for all preview rules. This allows users to enable preview
without opting into all preview rules at once.
## Test plan
Unit tests
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.
Closes#5497
Needs MkDocs 1.5 to be released.
- [x] https://github.com/mkdocs/mkdocs/milestone/15
## Summary
Uses MkDocs' `not_in_nav` config to hide spam about files in
`docs/rules/` not being in nav.
## Summary
We're planning to move the documentation from
[https://beta.ruff.rs/docs](https://beta.ruff.rs/docs) to
[https://docs.astral.sh/ruff](https://docs.astral.sh/ruff), for a few
reasons:
1. We want to remove the `beta` from the domain, as Ruff is no longer
considered beta software.
2. We want to migrate to a structure that could accommodate multiple
future tools living under one domain.
The docs are actually already live at
[https://docs.astral.sh/ruff](https://docs.astral.sh/ruff), but later
today, I'll add a permanent redirect from the previous to the new
domain. **All existing links will continue to work, now and in
perpetuity.**
This PR contains the code changes necessary for the updated
documentation. As part of this effort, I moved the playground and
documentation from my personal Cloudflare account to our team Cloudflare
account (hence the new `--project-name` references). After merging, I'll
also update the secrets on this repo.
## Summary
Adds `LOG009` from
[flake8-logging](https://github.com/adamchainz/flake8-logging). Also
adds the boilerplate for a new plugin
Checks for usages of undocumented `logging.WARN` constant and suggests
replacement with `logging.WARNING`.
## Test Plan
`cargo test` with fresh fixture
## Issue links
Refers: https://github.com/astral-sh/ruff/issues/7248
## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Extends work in #7046 (some relevant discussion there)
Changes:
- All nursery rules are now referred to as preview rules
- Documentation for the nursery is updated to describe preview
- Adds a "PREVIEW" selector for preview rules
- This is primarily to allow `--preview --ignore PREVIEW --extend-select
FOO001,BAR200`
- Using `--preview` enables preview rules that match selectors
Notable decisions:
- Preview rules are not selectable by their rule code without enabling
preview
- Retains the "NURSERY" selector for backwards compatibility
- Nursery rules are selectable by their rule code for backwards
compatiblity
Additional work:
- Selection of preview rules without the "--preview" flag should display
a warning
- Use of deprecated nursery selection behavior should display a warning
- Nursery selection should be removed after some time
## Test Plan
<!-- How was it tested? -->
Manual confirmation (i.e. we don't have an preview rules yet just
nursery rules so I added a preview rule for manual testing)
New unit tests

## Summary
Hi! This is my first PR to `ruff` and thanks for this amazing project.
While I am working on my project, I need to set different rules for my
`test/` folder and the main `src` package.
It's not immediately obvious that the
[`tool.ruff.per-file-ignores`](https://beta.ruff.rs/docs/settings/#per-file-ignores)
support regular expression. It is useful to set rules on directory
level. The PR add a simple example to make it clear this support regex.
The target version should be the oldest supported version instead of an
arbitary version. Since 3.7 is EOL, we should use 3.8. I would like to
follow this up with more comprehensive default detection based on the
environment.
## Summary
This PR migrates our `mkdocs-material` version to
[Insiders](https://squidfunk.github.io/mkdocs-material/insiders/), which
we can access now that we're sponsors.
We can't allow public access to the Insiders version, so we instead have
a private fork, which contains a deploy key that I've added as a
read-only Actions secret in this repo. (That is: the deploy key only
lets you read that one repo, and do nothing else.)
In general, non-Astral contributors can use the non-insiders version,
and everything is expected to "work", but without the insiders features
(they're intended to be ignored). See:
https://squidfunk.github.io/mkdocs-material/insiders/#compatibility.
## Summary
This adds a `ruff rule --all` switch that prints out a human-readable
Markdown or a machine-readable JSON document of the lint rules known to
Ruff.
I needed a machine-readable document of the rules [for a
project](https://github.com/astral-sh/ruff/discussions/5078), and
figured it could be useful for other people – or tooling! – to be able
to interrogate Ruff about its arcane knowledge.
The JSON output is an array of the same objects printed by `ruff rule
--format=json`.
## Test Plan
I ran `ruff rule --all --format=json`. I think more might be needed, but
maybe a snapshot test is overkill?
## 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
A new CLI option (`-o`/`--output-file`) to write output to a file
instead of stdout.
Major change is to remove the lock acquired on stdout. The argument is
that the output is buffered and thus the lock is acquired only when
writing a block (8kb). As per the benchmark below there is a slight
performance penalty.
Reference:
https://rustmagazine.org/issue-3/javascript-compiler/#printing-is-slow
## Benchmarks
_Output is truncated to only contain useful information:_
Command: `check --isolated --no-cache --select=ALL --show-source
./test-repos/cpython"`
Latest HEAD (361d45f2b2) with and without
the manual lock on stdout:
```console
Benchmark 1: With lock
Time (mean ± σ): 5.687 s ± 0.075 s [User: 17.110 s, System: 0.486 s]
Range (min … max): 5.615 s … 5.860 s 10 runs
Benchmark 2: Without lock
Time (mean ± σ): 5.719 s ± 0.064 s [User: 17.095 s, System: 0.491 s]
Range (min … max): 5.640 s … 5.865 s 10 runs
Summary
(1) ran 1.01 ± 0.02 times faster than (2)
```
This PR:
```console
Benchmark 1: This PR
Time (mean ± σ): 5.855 s ± 0.058 s [User: 17.197 s, System: 0.491 s]
Range (min … max): 5.786 s … 5.987 s 10 runs
Benchmark 2: Latest HEAD with lock
Time (mean ± σ): 5.645 s ± 0.033 s [User: 16.922 s, System: 0.495 s]
Range (min … max): 5.600 s … 5.712 s 10 runs
Summary
(2) ran 1.04 ± 0.01 times faster than (1)
```
## Test Plan
Run all of the commands which gives output with and without the
`--output-file=ruff.out` option:
* `--show-settings`
* `--show-files`
* `--show-fixes`
* `--diff`
* `--select=ALL`
* `--select=All --show-source`
* `--watch` (only stdout allowed)
resolves: #4754
## Summary
This adds `json-lines` (https://jsonlines.org/ or http://ndjson.org/) as
an output format.
I'm sure you already know, but
* JSONL is more greppable (each record is a single line) than the pretty
JSON
* JSONL is faster to ingest piecewise (and/or in parallel) than JSON
## Test Plan
Snapshot test in the new module :)
## Summary
Add copyright notice detection to enforce the presence of copyright
headers in Python files.
Configurable settings include: the relevant regular expression, the
author name, and the minimum file size, similar to
[flake8-copyright](https://github.com/savoirfairelinux/flake8-copyright).
