## Summary
Per
https://github.com/astral-sh/ruff/issues/20191#issuecomment-3251131478,
this PR restructures the license file to draw a distinction between
projects from which we've (e.g.) drawn source code and projects whose
rules we've implemented but have otherwise not reused or adapted source
code from, which are credited in the README. While I was here, I also
sorted the list.
## Summary
These are the first rules implemented as part of #458, but I plan to
implement more.
Specifically, this implements `docstring-missing-exception` which checks
for raised exceptions not documented in the docstring, and
`docstring-extraneous-exception` which checks for exceptions in the
docstring not present in the body.
## Test Plan
Test fixtures added for both google and numpy style.
## Summary
This PR updates the flake8-self license from Freely Distributable to the
MIT License to match the upstream license, which was recently updated.
f5fc507515/LICENSE
## 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

## Summary
This PR contains the first step towards enabling robust first-party,
third-party, and standard library import resolution in Ruff (including
support for `typeshed`, stub files, native modules, etc.) by porting
Pyright's import resolver to Rust.
The strategy taken here was to start with a more-or-less direct port of
the Pyright's TypeScript resolver. The code is intentionally similar,
and the test suite is effectively a superset of Pyright's test suite for
its own resolver. Due to the nature of the port, the code is very, very
non-idiomatic for Rust. The code is also entirely unused outside of the
test suite, and no effort has been made to integrate it with the rest of
the codebase.
Future work will include:
- Refactoring the code (now that it works) to match Rust and Ruff
idioms.
- Further testing, in practice, to ensure that the resolver can resolve
imports in a complex project, when provided with a virtual environment
path.
- Caching, to minimize filesystem lookups and redundant resolutions.
- Integration into Ruff itself (use Ruff's existing settings, find rules
that can make use of robust resolution, etc.)
This PR removes the dependency on `ruff_rowan` (i.e., Rome's fork of rust-analyzer's `rowan`), and in turn, trims out a lot of code in `ruff_formatter` that isn't necessary (or isn't _yet_ necessary) to power the autoformatter.
We may end up pulling some of this back in -- TBD. For example, the autoformatter has its own comment representation right now, but we may eventually want to use the `comments.rs` data structures defined in `rome_formatter`.
The Ruff autoformatter is going to be based on an intermediate representation (IR) formatted via [Wadler's algorithm](https://homepages.inf.ed.ac.uk/wadler/papers/prettier/prettier.pdf). This is architecturally similar to [Rome](https://github.com/rome/tools), Prettier, [Skip](https://github.com/skiplang/skip/blob/master/src/tools/printer/printer.sk), and others.
This PR adds a fork of the `rome_formatter` crate from [Rome](https://github.com/rome/tools), renamed here to `ruff_formatter`, which provides generic definitions for a formatter IR as well as a generic IR printer. (We've also pulled in `rome_rowan`, `rome_text_size`, and `rome_text_edit`, though some of these will be removed in future PRs.)
Why fork? `rome_formatter` contains code that's specific to Rome's AST representation (e.g., it relies on a fork of rust-analyzer's `rowan`), and we'll likely want to support different abstractions and formatting capabilities (there are already a few changes coming in future PRs). Once we've dropped `ruff_rowan` and trimmed down `ruff_formatter` to the code we currently need, it's also not a huge surface area to maintain and update.
These were split into per-project licenses in #1648, but I don't like that they're no longer included in the distribution (due to current limitations in the `pyproject.toml` spec).
