-# Various formats will be parsed into a VERSION and an optional PACKAGE_NAME, where
-# PACKAGE_NAME must be the name of a Cargo package in your workspace, and VERSION
-# must be a Cargo-style SemVer Version (must have at least major.minor.patch).
-#
-# If PACKAGE_NAME is specified, then the announcement will be for that
-# package (erroring out if it doesn't have the given version or isn't cargo-dist-able).
-#
-# If PACKAGE_NAME isn't specified, then the announcement will be for all
-# (cargo-dist-able) packages in the workspace with that version (this mode is
-# intended for workspaces with only one dist-able package, or with all dist-able
-# packages versioned/released in lockstep).
-#
-# If you push multiple tags at once, separate instances of this workflow will
-# spin up, creating an independent announcement for each one. However, GitHub
-# will hard limit this to 3 tags per commit, as it will assume more tags is a
-# mistake.
-#
-# If there's a prerelease-style suffix to the version, then the release(s)

 # Breaking Changes
 
-## 0.5.0
-
-- Follow the XDG specification to discover user-level configurations on macOS (same as on other Unix platforms)
-- Selecting `ALL` now excludes deprecated rules
-- The released archives now include an extra level of nesting, which can be removed with `--strip-components=1` when untarring.
-- The release artifact's file name no longer includes the version tag. This enables users to install via `/latest` URLs on GitHub.
-
-## 0.3.0
-
-### Ruff 2024.2 style
-
-The formatter now formats code according to the Ruff 2024.2 style guide. Read the [changelog](./CHANGELOG.md#030) for a detailed list of stabilized style changes.
-
-### `isort`: Use one blank line after imports in typing stub files ([#9971](https://github.com/astral-sh/ruff/pull/9971))
-
-Previously, Ruff used one or two blank lines (or the number configured by `isort.lines-after-imports`) after imports in typing stub files (`.pyi` files).
-The [typing style guide for stubs](https://typing.readthedocs.io/en/latest/source/stubs.html#style-guide) recommends using at most 1 blank line for grouping.
-As of this release, `isort` now always uses one blank line after imports in stub files, the same as the formatter.
-
-### `build` is no longer excluded by default ([#10093](https://github.com/astral-sh/ruff/pull/10093))
-
-Ruff maintains a list of directories and files that are excluded by default. This list now consists of the following patterns:
-
-- `.bzr`
-- `.direnv`
-- `.eggs`
-- `.git`
-- `.git-rewrite`
-- `.hg`
-- `.ipynb_checkpoints`
-- `.mypy_cache`
-- `.nox`
-- `.pants.d`
-- `.pyenv`
-- `.pytest_cache`
-- `.pytype`
-- `.ruff_cache`
-- `.svn`
-- `.tox`
-- `.venv`
-- `.vscode`
-- `__pypackages__`
-- `_build`
-- `buck-out`
-- `dist`
-- `node_modules`
-- `site-packages`
-- `venv`
-
-Previously, the `build` directory was included in this list. However, the `build` directory tends to be a not-unpopular directory
-name, and excluding it by default caused confusion. Ruff now no longer excludes `build` except if it is excluded by a `.gitignore` file
-or because it is listed in `extend-exclude`.
-
-### `--format` is no longer a valid `rule` or `linter` command option
-
-Previously, `ruff rule` and `ruff linter` accepted the `--format <FORMAT>` option as an alias for `--output-format`. Ruff no longer
-supports this alias. Please use `ruff rule --output-format <FORMAT>` and `ruff linter --output-format <FORMAT>` instead.
-
-## 0.1.9
-
-### `site-packages` is now excluded by default ([#5513](https://github.com/astral-sh/ruff/pull/5513))
-
-Ruff maintains a list of default exclusions, which now consists of the following patterns:
-
-- `.bzr`
-- `.direnv`
-- `.eggs`
-- `.git-rewrite`
-- `.git`
-- `.hg`
-- `.ipynb_checkpoints`
-- `.mypy_cache`
-- `.nox`
-- `.pants.d`
-- `.pyenv`
-- `.pytest_cache`
-- `.pytype`
-- `.ruff_cache`
-- `.svn`
-- `.tox`
-- `.venv`
-- `.vscode`
-- `__pypackages__`
-- `_build`
-- `buck-out`
-- `build`
-- `dist`
-- `node_modules`
-- `site-packages`
-- `venv`
-
-Previously, the `site-packages` directory was not excluded by default. While `site-packages` tends
-to be excluded anyway by virtue of the `.venv` exclusion, this may not be the case when using Ruff
-from VS Code outside a virtual environment.
-
-## 0.1.0
-
-### The deprecated `format` setting has been removed
-
-Ruff previously used the `format` setting, `--format` CLI option, and `RUFF_FORMAT` environment variable to
-configure the output format of the CLI. This usage was deprecated in `v0.0.291` — the `format` setting is now used
-to control Ruff's code formatting. As of this release:
-
-- The `format` setting cannot be used to configure the output format, use `output-format` instead
-- The `RUFF_FORMAT` environment variable is ignored, use `RUFF_OUTPUT_FORMAT` instead
-- The `--format` option has been removed from `ruff check`, use `--output-format` instead
-
-### Unsafe fixes are not applied by default ([#7769](https://github.com/astral-sh/ruff/pull/7769))
-
-Ruff labels fixes as "safe" and "unsafe". The meaning and intent of your code will be retained when applying safe

-### Remove formatter-conflicting rules from the default rule set  ([#7900](https://github.com/astral-sh/ruff/pull/7900))
-
-Previously, Ruff enabled all implemented rules in Pycodestyle (`E`) by default. Ruff now only includes the
-Pycodestyle prefixes `E4`, `E7`, and `E9` to exclude rules that conflict with automatic formatters. Consequently,
-the stable rule set no longer includes `line-too-long` (`E501`) and `mixed-spaces-and-tabs` (`E101`). Other
-excluded Pycodestyle rules include whitespace enforcement in `E1` and `E2`; these rules are currently in preview, and are already omitted by default.
-
-This change only affects those using Ruff under its default rule set. Users that include `E` in their `select` will experience no change in behavior.

+[_Adding a new lint rule_](#example-adding-a-new-lint-rule), which will allow you to learn from and
+pattern-match against the examples in the existing codebase. Many lint rules are inspired by
+existing Python plugins, which can be used as a reference implementation.
+
+As a concrete example: consider taking on one of the rules from the [`flake8-pyi`](https://github.com/astral-sh/ruff/issues/848)

+# flake8-to-ruff
+
+Convert existing Flake8 configuration files (`setup.cfg`, `tox.ini`, or `.flake8`) for use with
+[Ruff](https://github.com/astral-sh/ruff).
+
+Generates a Ruff-compatible `pyproject.toml` section.
+
+## Installation and Usage
+
+### Installation
+
+Available as [`flake8-to-ruff`](https://pypi.org/project/flake8-to-ruff/) on PyPI:
+
+```shell
+pip install flake8-to-ruff
+```
+
+### Usage
+
+To run `flake8-to-ruff`:
+
+```shell
+flake8-to-ruff path/to/setup.cfg
+flake8-to-ruff path/to/tox.ini
+flake8-to-ruff path/to/.flake8
+```
+
+`flake8-to-ruff` will print the relevant `pyproject.toml` sections to standard output, like so:
+
+```toml
+[tool.ruff]
+exclude = [
+    '.svn',
+    'CVS',
+    '.bzr',
+    '.hg',
+    '.git',
+    '__pycache__',
+    '.tox',
+    '.idea',
+    '.mypy_cache',
+    '.venv',
+    'node_modules',
+    '_state_machine.py',
+    'test_fstring.py',
+    'bad_coding2.py',
+    'badsyntax_*.py',
+]
+select = [
+    'A',
+    'E',
+    'F',
+    'Q',
+]
+ignore = []
+
+[tool.ruff.flake8-quotes]
+inline-quotes = 'single'
+
+[tool.ruff.pep8-naming]
+ignore-names = [
+    'foo',
+    'bar',
+]
+```
+
+### Plugins
+
+`flake8-to-ruff` will attempt to infer any activated plugins based on the settings provided in your
+configuration file.
+
+For example, if your `.flake8` file includes a `docstring-convention` property, `flake8-to-ruff`
+will enable the appropriate [`flake8-docstrings`](https://pypi.org/project/flake8-docstrings/)
+checks.
+
+Alternatively, you can manually specify plugins on the command-line:
+
+```shell
+flake8-to-ruff path/to/.flake8 --plugin flake8-builtins --plugin flake8-quotes
+```
+
+## Limitations
+
+1. Ruff only supports a subset of the Flake configuration options. `flake8-to-ruff` will warn on and
+    ignore unsupported options in the `.flake8` file (or equivalent). (Similarly, Ruff has a few
+    configuration options that don't exist in Flake8.)
+1. Ruff will omit any rule codes that are unimplemented or unsupported by Ruff, including rule
+    codes from unsupported plugins. (See the
+    [documentation](https://docs.astral.sh/ruff/faq/#how-does-ruff-compare-to-flake8) for the complete
+    list of supported plugins.)

-/// The project workspace as a Salsa ingredient.
-///
-/// A workspace consists of one or multiple packages. Packages can be nested. A file in a workspace
-/// belongs to no or exactly one package (files can't belong to multiple packages).
-///
-/// How workspaces and packages are discovered is TBD. For now, a workspace can be any directory,
-/// and it always contains a single package which has the same root as the workspace.
-///
-/// ## Examples
-///
-/// ```text
-/// app-1/
-///     pyproject.toml
-///     src/
-///         ... python files
-///
-/// app-2/
-///     pyproject.toml
-///     src/
-///         ... python files
-///
-/// shared/
-///     pyproject.toml
-///     src/
-///         ... python files
-///
-/// pyproject.toml
-/// ```
-///
-/// The above project structure has three packages: `app-1`, `app-2`, and `shared`.
-/// Each of the packages can define their own settings in their `pyproject.toml` file, but
-/// they must be compatible. For example, each package can define a different `requires-python` range,
-/// but the ranges must overlap.
-///
-/// ## How is a workspace different from a program?
-/// There are two (related) motivations:
-///
-/// 1. Program is defined in `ruff_db` and it can't reference the settings types for the linter and formatter
-///    without introducing a cyclic dependency. The workspace is defined in a higher level crate
-///    where it can reference these setting types.
-/// 2. Running `ruff check` with different target versions results in different programs (settings) but
-///    it remains the same workspace. That's why program is a narrowed view of the workspace only
-///    holding on to the most fundamental settings required for checking.

-# Red Knot

-A work-in-progress multifile module resolver for Ruff.
-
-## Vendored types for the stdlib
-
-This crate vendors [typeshed](https://github.com/python/typeshed)'s stubs for the standard library. The vendored stubs can be found in `crates/red_knot_module_resolver/vendor/typeshed`. The file `crates/red_knot_module_resolver/vendor/typeshed/source_commit.txt` tells you the typeshed commit that our vendored stdlib stubs currently correspond to.
-
-The typeshed stubs are updated every two weeks via an automated PR using the `sync_typeshed.yaml` workflow in the `.github/workflows` directory. This workflow can also be triggered at any time via [workflow dispatch](https://docs.github.com/en/actions/using-workflows/manually-running-a-workflow#running-a-workflow).

-/// The builder takes care of creating a [`TestDb`]
-/// instance, applying the module resolver settings,
-/// and creating mock directories for the stdlib, `site-packages`,
-/// first-party code, etc.
-///
-/// For simple tests that do not involve typeshed,
-/// test cases can be created as follows:
-///
-/// ```rs
-/// let test_case = TestCaseBuilder::new()
-///     .with_src_files(...)
-///     .build();
-///
-/// let test_case2 = TestCaseBuilder::new()
-///     .with_site_packages_files(...)
-///     .build();
-/// ```

-/// Any tests can specify the target Python version that should be used
-/// in the module resolver settings:
-///
-/// ```rs
-/// let test_case = TestCaseBuilder::new()
-///     .with_src_files(...)
-///     .with_target_version(...)
-///     .build();
-/// ```
-///
-/// For tests checking that standard-library module resolution is working
-/// correctly, you should usually create a [`MockedTypeshed`] instance
-/// and pass it to the [`TestCaseBuilder::with_custom_typeshed`] method.
-/// If you need to check something that involves the vendored typeshed stubs
-/// we include as part of the binary, you can instead use the
-/// [`TestCaseBuilder::with_vendored_typeshed`] method.
-/// For either of these, you should almost always try to be explicit
-/// about the Python version you want to be specified in the module-resolver
-/// settings for the test:
-///
-/// ```rs
-/// const TYPESHED = MockedTypeshed { ... };
-///
-/// let test_case = resolver_test_case()
-///     .with_custom_typeshed(TYPESHED)
-///     .with_target_version(...)

-/// let test_case2 = resolver_test_case()
-///     .with_vendored_typeshed()
-///     .with_target_version(...)
-///     .build();

-///
-/// If you have not called one of those options, the `stdlib` field
-/// on the [`TestCase`] instance created from `.build()` will be set

-[![Tests](https://github.com/python/typeshed/actions/workflows/tests.yml/badge.svg)](https://github.com/python/typeshed/actions/workflows/tests.yml)
-[![Chat at https://gitter.im/python/typing](https://badges.gitter.im/python/typing.svg)](https://gitter.im/python/typing?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
-[![Pull Requests Welcome](https://img.shields.io/badge/pull%20requests-welcome-brightgreen.svg)](https://github.com/python/typeshed/blob/main/CONTRIBUTING.md)
-
-## About
-
-Typeshed contains external type annotations for the Python standard library
-and Python builtins, as well as third party packages as contributed by
-people external to those projects.
-
-This data can e.g. be used for static analysis, type checking, type inference,
-and autocompletion.
-
-For information on how to use typeshed, read below.  Information for
-contributors can be found in [CONTRIBUTING.md](CONTRIBUTING.md).  **Please read
-it before submitting pull requests; do not report issues with annotations to
-the project the stubs are for, but instead report them here to typeshed.**
-
-Further documentation on stub files, typeshed, and Python's typing system in
-general, can also be found at https://typing.readthedocs.io/en/latest/.
-
-Typeshed supports Python versions 3.8 and up.
-
-## Using
-
-If you're just using a type checker ([mypy](https://github.com/python/mypy/),
-[pyright](https://github.com/microsoft/pyright),
-[pytype](https://github.com/google/pytype/), PyCharm, ...), as opposed to
-developing it, you don't need to interact with the typeshed repo at
-all: a copy of standard library part of typeshed is bundled with type checkers.
-And type stubs for third party packages and modules you are using can
-be installed from PyPI. For example, if you are using `html5lib` and `requests`,
-you can install the type stubs using
-
-```bash
-$ pip install types-html5lib types-requests
-```
-
-These PyPI packages follow [PEP 561](http://www.python.org/dev/peps/pep-0561/)
-and are automatically released (up to once a day) by
-[typeshed internal machinery](https://github.com/typeshed-internal/stub_uploader).
-
-Type checkers should be able to use these stub packages when installed. For more
-details, see the documentation for your type checker.
-
-### Package versioning for third-party stubs
-
-Version numbers of third-party stub packages consist of at least four parts.
-All parts of the stub version, except for the last part, correspond to the
-version of the runtime package being stubbed. For example, if the `types-foo`
-package has version `1.2.0.20240309`, this guarantees that the `types-foo` package
-contains stubs targeted against `foo==1.2.*` and tested against the latest
-version of `foo` matching that specifier. In this example, the final element
-of the version number (20240309) indicates that the stub package was pushed on
-March 9, 2024.
-
-At typeshed, we try to keep breaking changes to a minimum. However, due to the
-nature of stubs, any version bump can introduce changes that might make your
-code fail to type check.
-
-There are several strategies available for specifying the version of a stubs
-package you're using, each with its own tradeoffs:
-
-1. Use the same bounds that you use for the package being stubbed. For example,
-   if you use `requests>=2.30.0,<2.32`, you can use
-   `types-requests>=2.30.0,<2.32`. This ensures that the stubs are compatible
-   with the package you are using, but it carries a small risk of breaking
-   type checking due to changes in the stubs.
-
-   Another risk of this strategy is that stubs often lag behind
-   the package being stubbed. You might want to force the package being stubbed
-   to a certain minimum version because it fixes a critical bug, but if
-   correspondingly updated stubs have not been released, your type
-   checking results may not be fully accurate.
-2. Pin the stubs to a known good version and update the pin from time to time
-   (either manually, or using a tool such as dependabot or renovate).
-
-   For example, if you use `types-requests==2.31.0.1`, you can have confidence
-   that upgrading dependencies will not break type checking. However, you will
-   miss out on improvements in the stubs that could potentially improve type
-   checking until you update the pin. This strategy also has the risk that the
-   stubs you are using might become incompatible with the package being stubbed.
-3. Don't pin the stubs. This is the option that demands the least work from
-   you when it comes to updating version pins, and has the advantage that you
-   will automatically benefit from improved stubs whenever a new version of the
-   stubs package is released. However, it carries the risk that the stubs
-   become incompatible with the package being stubbed.
-
-   For example, if a new major version of the package is released, there's a
-   chance the stubs might be updated to reflect the new version of the runtime
-   package before you update the package being stubbed.
-
-You can also switch between the different strategies as needed. For example,
-you could default to strategy (1), but fall back to strategy (2) when
-a problem arises that can't easily be fixed.
-
-### The `_typeshed` package
-
-typeshed includes a package `_typeshed` as part of the standard library.
-This package and its submodules contain utility types, but are not
-available at runtime. For more information about how to use this package,
-[see the `stdlib/_typeshed` directory](https://github.com/python/typeshed/tree/main/stdlib/_typeshed).
-
-## Discussion
-
-If you've run into behavior in the type checker that suggests the type
-stubs for a given library are incorrect or incomplete,
-we want to hear from you!
-
-Our main forum for discussion is the project's [GitHub issue
-tracker](https://github.com/python/typeshed/issues).  This is the right
-place to start a discussion of any of the above or most any other
-topic concerning the project.
-
-If you have general questions about typing with Python, or you need
-a review of your type annotations or stubs outside of typeshed, head over to
-[our discussion forum](https://github.com/python/typing/discussions).
-For less formal discussion, try the typing chat room on
-[gitter.im](https://gitter.im/python/typing).  Some typeshed maintainers
-are almost always present; feel free to find us there and we're happy
-to chat.  Substantive technical discussion will be directed to the
-issue tracker.

-# The structure of this file is as follows:
-# - Blank lines and comments starting with `#` are ignored.
-# - Lines contain the name of a module, followed by a colon,
-#   a space, and a version range (for example: `symbol: 3.0-3.9`).
-#
-# Version ranges may be of the form "X.Y-A.B" or "X.Y-". The
-# first form means that a module was introduced in version X.Y and last
-# available in version A.B. The second form means that the module was
-# introduced in version X.Y and is still available in the latest
-# version of Python.
-#
-# If a submodule is not listed separately, it has the same lifetime as
-# its parent module.
-#
-# Python versions before 3.0 are ignored, so any module that was already
-# present in 3.0 will have "3.0" as its minimum version. Version ranges
-# for unsupported versions of Python 3 are generally accurate but we do
-# not guarantee their correctness.
