## Summary
This PR moves `ruff/jupyter` into its own `ruff_notebook` crate. Beyond
the move itself, there were a few challenges:
1. `ruff_notebook` relies on the source map abstraction. I've moved the
source map into `ruff_diagnostics`, since it doesn't have any
dependencies on its own and is used alongside diagnostics.
2. `ruff_notebook` has a couple tests for end-to-end linting and
autofixing. I had to leave these tests in `ruff` itself.
3. We had code in `ruff/jupyter` that relied on Python lexing, in order
to provide a more targeted error message in the event that a user saves
a `.py` file with a `.ipynb` extension. I removed this in order to avoid
a dependency on the parser, it felt like it wasn't worth retaining just
for that dependency.
## Test Plan
`cargo test`
**Summary** Some files seems notoriously slow in the formatter (secons in debug mode). This time was however almost exclusively spent in the diff algorithm to collect the similarity index, so i replaced that. I kept `similar` for printing actual diff to avoid rewriting that too, with the disadvantage that we now have to diff libraries in format_dev.
I used this PR to remove the spinner from tracing-indicatif and changed `flamegraph --perfdata perf.data` to `flamegraph --perfdata perf.data --no-inline` as the former wouldn't finish for me on release builds with debug info.
## Summary
Comparing repos with black requires that we use the settings as black,
notably line length and magic trailing comma behaviour. Excludes and
preserving quotes (vs. a preference for either quote style) is not yet
implemented because they weren't needed for the test projects.
In the other two commits i fixed the output when the progress bar is
hidden (this way is recommonded in the indicatif docs), added a
`scratch.pyi` file to gitignore because black formats stub files
differently and also updated the ecosystem readme with the projects json
without forks.
## Test Plan
I added a `line-length` vs `line_length` test. Otherwise only my
personal usage atm, a PR to integrate the script into the CI to check
some projects will follow.
## 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 PR uses rayon to parallelize the stability check by scheduling each project as its own task.
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
I ran the ecosystem check. It now makes use of all cores (except at the end, there are some large projects).
## Performance
The check now completes in minutes where it took about 30 minutes before.
<!-- How was it tested? -->
## 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
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.
This adds a new subcommand to `ruff_dev` which can be invoked as `cargo
run --bin ruff_dev -- check-formatter-stability <repo>`. While initially
only intended to check stability, it has also found cases where the
formatter printed invalid syntax or panicked.
## Test Plan
Running this on cpython is already identifying bugs
(https://github.com/astral-sh/ruff/pull/5089)
## Summary
This PR moves `Diagnostic`, `DiagnosticKind`, and `Fix` into their own crate, which will enable us to further split up Ruff, since sub-linter crates (which need to implement functions that return `Diagnostic`) can now depend on `ruff_diagnostics` rather than Ruff.
In 28c9263722 I introduced automatic
linkification of option references in rule documentation,
which automatically converted the following:
## Options
* `namespace-packages`
to:
## Options
* [`namespace-packages`]
[`namespace-packages`]: ../../settings#namespace-packages
While the above is a correct CommonMark[1] link definition,
what I was missing was that we used mkdocs for our documentation
generation, which as it turns out uses a non-CommonMark-compliant
Markdown parser, namely Python-Markdown, which contrary to CommonMark
doesn't support link definitions containing code tags.
This commit fixes the broken links via a regex hack.
