## 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.
## Summary
Maintain consistency while deserializing Jupyter notebook to JSON. The
following changes were made:
1. Use string array to store the source value as that's the default
(5781720423/nbformat/v4/nbjson.py (L56-L57))
2. Remove unused structs and enums
3. Reorder the keys in alphabetical order as that's the default.
(5781720423/nbformat/v4/nbjson.py (L51))
### Side effect
Removing the `preserve_order` feature means that the order of keys in
JSON output (`--format json`) will be in alphabetical order. This is
because the value is represented using `serde_json::Value` which
internally is a `BTreeMap`, thus sorting it as per the string key. For
posterity if this turns out to be not ideal, then we could define a
struct representing the JSON object and the order of struct fields will
determine the order in the JSON string.
## Test Plan
Add a test case to assert the raw JSON string.
## 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
