## 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.
```
❯ 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`.
- 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
I noticed that we have a custom parser for rule selectors, but it wasn't
actually being used? This PR adds it back to our Clap setup and changes
the parser to only show full categories and individual rules when
tab-completing:

The previous implementation showed all codes, which I found too noisy:

## 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
