## 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
This PR upgrades `strum` from 0.24.x to 0.25.x.
The breaking changes are:
* strum macros now uses syn2
* The `to_string` behavior changed when using `default`. I did a quick search, we aren't using `strum(default)`
`strum` now has a `#[derive(EnumIs)]` macro that generates `is_` methods.
## Test Plan
cargo test
## Summary
This PR updates the revision of `LibCST` dependency to 9c263aa897
inorder to fix https://github.com/astral-sh/ruff/issues/4899
## Test Plan
The test case including the carriage return (`\r`) character was added for
`F504` and then `cargo test`.
fixes: #4899
## Summary
This PR adds the implementation for the new Jupyter AST nodes i.e.,
`ExprLineMagic` and `StmtLineMagic`.
## Test Plan
Add test cases for `unparse` containing magic commands
resolves: #6087
**Summary** I accidentally merged earlier while the RustPython parser
rev was still pointing to the feature branch instead of to the merged
main. This make the rev point to the RustPython parser repo main again
**Summary** Fix implemented in
https://github.com/astral-sh/RustPython-Parser/pull/35: Previously,
empty lambda arguments (e.g. `lambda: 1`) would get the range of the
entire expression, which leads to incorrect comment placement. Now empty
lambda arguments get an empty range between the `lambda` and the `:`
tokens.
**Test Plan** Added a regression test.
149 instances of unstable formatting remaining.

$ cargo run --bin ruff_dev --release -- format-dev --stability-check --error-file formatter-ecosystem-errors.txt --multi-project target/checkouts > formatter-ecosystem-progress.txt
$ rg "Unstable formatting" target/formatter-ecosystem-errors.txt | wc -l

```
## Summary
It can happen that we can't read a file (a python file, a jupyter
notebook or pyproject.toml), which needs to be handled and handled
consistently for all file types. Instead of using `Err` or `error!`, we
emit E602 with the io error as message and continue. This PR makes sure
we handle all three cases consistently, emit E602.
I'm not convinced that it should be possible to disable io errors, but
we now handle the regular case consistently and at least print warning
consistently.
I went with `warn!` but i can change them all to `error!`, too.
It also checks the error case when a pyproject.toml is not readable. The
error message is not very helpful, but it's now a bit clearer that
actually ruff itself failed instead vs this being a diagnostic.
## Examples
This is how an Err of `run` looks now:
With an unreadable file and `IOError` disabled:
(we lint zero files but count files before linting not during so we exit
0)
I'm not sure if it should (or if we should take a different path with
manual ExitStatus), but this currently also triggers when `files` is
empty:
## Test Plan
Unix only: Create a temporary directory with files with permissions
`000` (not readable by the owner) and run on that directory. Since this
breaks the assumptions of most of the test code (single file, `ruff`
instead of `ruff_cli`), the test code is rather cumbersome and looks a
bit misplaced; i'm happy about suggestions to fit it in closer with the
other tests or streamline it in other ways. I added another test for
when the entire directory is not readable.
Following https://github.com/astral-sh/RustPython-Parser/pull/27 we now
cherry-pick commits onto our fork instead of rebasing our fork on top of
the upstream which means we do not overwrite history and a tag is not
necessary to preserve the pinned commit.
In the future, we may rewrite the history in our fork. If we do, we
should return to tagging the commits.
## Summary
Previously, `StmtIf` was defined recursively as
```rust
pub struct StmtIf {
pub range: TextRange,
pub test: Box<Expr>,
pub body: Vec<Stmt>,
pub orelse: Vec<Stmt>,
}
```
Every `elif` was represented as an `orelse` with a single `StmtIf`. This
means that this representation couldn't differentiate between
```python
if cond1:
x = 1
else:
if cond2:
x = 2
```
and
```python
if cond1:
x = 1
elif cond2:
x = 2
```
It also makes many checks harder than they need to be because we have to
recurse just to iterate over an entire if-elif-else and because we're
lacking nodes and ranges on the `elif` and `else` branches.
We change the representation to a flat
```rust
pub struct StmtIf {
pub range: TextRange,
pub test: Box<Expr>,
pub body: Vec<Stmt>,
pub elif_else_clauses: Vec<ElifElseClause>,
}
pub struct ElifElseClause {
pub range: TextRange,
pub test: Option<Expr>,
pub body: Vec<Stmt>,
}
```
where `test: Some(_)` represents an `elif` and `test: None` an else.
This representation is different tradeoff, e.g. we need to allocate the
`Vec<ElifElseClause>`, the `elif`s are now different than the `if`s
(which matters in rules where want to check both `if`s and `elif`s) and
the type system doesn't guarantee that the `test: None` else is actually
last. We're also now a bit more inconsistent since all other `else`,
those from `for`, `while` and `try`, still don't have nodes. With the
new representation some things became easier, e.g. finding the `elif`
token (we can use the start of the `ElifElseClause`) and formatting
comments for if-elif-else (no more dangling comments splitting, we only
have to insert the dangling comment after the colon manually and set
`leading_alternate_branch_comments`, everything else is taken of by
having nodes for each branch and the usual placement.rs fixups).
## Merge Plan
This PR requires coordination between the parser repo and the main ruff
repo. I've split the ruff part, into two stacked PRs which have to be
merged together (only the second one fixes all tests), the first for the
formatter to be reviewed by @michareiser and the second for the linter
to be reviewed by @charliermarsh.
* MH: Review and merge
https://github.com/astral-sh/RustPython-Parser/pull/20
* MH: Review and merge or move later in stack
https://github.com/astral-sh/RustPython-Parser/pull/21
* MH: Review and approve
https://github.com/astral-sh/RustPython-Parser/pull/22
* MH: Review and approve formatter PR
https://github.com/astral-sh/ruff/pull/5459
* CM: Review and approve linter PR
https://github.com/astral-sh/ruff/pull/5460
* Merge linter PR in formatter PR, fix ecosystem checks (ecosystem
checks can't run on the formatter PR and won't run on the linter PR, so
we need to merge them first)
* Merge https://github.com/astral-sh/RustPython-Parser/pull/22
* Create tag in the parser, update linter+formatter PR
* Merge linter+formatter PR https://github.com/astral-sh/ruff/pull/5459

## Summary
Do not raise `EXE001` and `EXE002` if WSL is detected. Uses the
[`wsl`](https://crates.io/crates/wsl) crate.
Closes#5445.
## Test Plan
`cargo test`
I don't use Windows, so was unable to test on a WSL environment. It
would be good if someone who runs Windows could check the functionality.

## Summary
Historically, we only used a fork to enable building without pyo3. But
pyo3 is an optional feature. I may've just not understood how to
accomplish this way back when.
## Summary
This extends the `ruff_dev` formatter script util. Instead of only doing
stability checks, you can now choose different compatible options on the
CLI and get statistics.
* It adds an option the formats all files that ruff would check to allow
looking at an entire black-formatted repository with `git diff`
* It computes the [Jaccard
index](https://en.wikipedia.org/wiki/Jaccard_index) as a measure of
deviation between input and output, which is useful as single number
metric for assessing our current deviations from black.
* It adds progress bars to both the single projects as well as the
multi-project mode.
* It adds an option to write the multi-project output to a file
Sample usage:
```
$ cargo run --bin ruff_dev -- format-dev --stability-check crates/ruff/resources/test/cpython
$ cargo run --bin ruff_dev -- format-dev --stability-check /home/konsti/projects/django
Syntax error in /home/konsti/projects/django/tests/test_runner_apps/tagged/tests_syntax_error.py: source contains syntax errors (parser error): BaseError { error: UnrecognizedToken(Name { name: "syntax_error" }, None), offset: 131, source_path: "<filename>" }
Found 0 stability errors in 2755 files (jaccard index 0.911) in 9.75s
$ cargo run --bin ruff_dev -- format-dev --write /home/konsti/projects/django
```
Options:
```
Several utils related to the formatter which can be run on one or more repositories. The selected set of files in a repository is the same as for `ruff check`.
* Check formatter stability: Format a repository twice and ensure that it looks that the first and second formatting look the same. * Format: Format the files in a repository to be able to check them with `git diff` * Statistics: The subcommand the Jaccard index between the (assumed to be black formatted) input and the ruff formatted output
Usage: ruff_dev format-dev [OPTIONS] [FILES]...
Arguments:
[FILES]...
Like `ruff check`'s files. See `--multi-project` if you want to format an ecosystem checkout
Options:
--stability-check
Check stability
We want to ensure that once formatted content stays the same when formatted again, which is known as formatter stability or formatter idempotency, and that the formatter prints syntactically valid code. As our test cases cover only a limited amount of code, this allows checking entire repositories.
--write
Format the files. Without this flag, the python files are not modified
--format <FORMAT>
Control the verbosity of the output
[default: default]
Possible values:
- minimal: Filenames only
- default: Filenames and reduced diff
- full: Full diff and invalid code
-x, --exit-first-error
Print only the first error and exit, `-x` is same as pytest
--multi-project
Checks each project inside a directory, useful e.g. if you want to check all of the ecosystem checkouts
--error-file <ERROR_FILE>
Write all errors to this file in addition to stdout. Only used in multi-project mode
```
## Test Plan
I ran this on django (2755 files, jaccard index 0.911) and discovered a
magic trailing comma problem and that we really needed to implement
import formatting. I ran the script on cpython to identify
https://github.com/astral-sh/ruff/pull/5558.
## 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
In https://github.com/astral-sh/RustPython-Parser/pull/8, we modified
RustPython to include ranges for any identifiers that aren't
`Expr::Name` (which already has an identifier).
For example, the `e` in `except ValueError as e` was previously
un-ranged. To extract its range, we had to do some lexing of our own.
This change should improve performance and let us remove a bunch of
code.
## Test Plan
`cargo test`
## Summary
This PR upgrade RustPython to pull in the changes to `Arguments` (zip
defaults with their identifiers) and all the renames to `CmpOp` and
friends.
## Summary
I want to include URLs to the rule documentation in the LSP (the LSP has
a native `code_description` field for this, which, if specified, causes
the source to be rendered as a link to the docs). This PR exposes the
URL to the documentation in the Ruff JSON output.
