-# This task will run whenever you workflow_dispatch with a tag that looks like a version
-# like "1.0.0", "v0.1.0-prerelease.1", "my-app/0.1.0", "releases/v1.0.0", etc.
-# 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)
-# will be marked as a prerelease.

 # 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`

-- `.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`

-- `__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
-fixes, but the meaning could be changed when applying unsafe fixes. Previously, unsafe fixes were always displayed
-and applied when fixing was enabled. Now, unsafe fixes are hidden by default and not applied. The `--unsafe-fixes`
-flag or `unsafe-fixes` configuration option can be used to enable unsafe fixes.
-
-See the [docs](https://docs.astral.sh/ruff/configuration/#fix-safety) for details.
-
-### 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.
-
-## 0.0.288
-
-### Remove support for emoji identifiers ([#7212](https://github.com/astral-sh/ruff/pull/7212))
-
-Previously, Ruff supported the non-standard compliant emoji identifiers e.g. `📦 = 1`.
-We decided to remove this non-standard language extension, and Ruff now reports syntax errors for emoji identifiers in your code, the same as CPython.
-
-### Improved GitLab fingerprints ([#7203](https://github.com/astral-sh/ruff/pull/7203))
-
-GitLab uses fingerprints to identify new, existing, or fixed violations. Previously, Ruff included the violation's position in the fingerprint. Using the location has the downside that changing any code before the violation causes the fingerprint to change, resulting in GitLab reporting one fixed and one new violation even though it is a pre-existing violation.
-
-Ruff now uses a more stable location-agnostic fingerprint to minimize that existing violations incorrectly get marked as fixed and re-reported as new violations.
-
-Expect GitLab to report each pre-existing violation in your project as fixed and a new violation in your Ruff upgrade PR.
-
-## 0.0.283 / 0.284
-
-### The target Python version now defaults to 3.8 instead of 3.10 ([#6397](https://github.com/astral-sh/ruff/pull/6397))
-
-Previously, when a target Python version was not specified, Ruff would use a default of Python 3.10. However, it is safer to default to an _older_ Python version to avoid assuming the availability of new features. We now default to the oldest supported Python version which is currently Python 3.8.
-
-(We still support Python 3.7 but since [it has reached EOL](https://devguide.python.org/versions/#unsupported-versions) we've decided not to make it the default here.)

-## 0.0.276
-
-### The `keep-runtime-typing` setting has been reinstated ([#5470](https://github.com/astral-sh/ruff/pull/5470))
-
-The `keep-runtime-typing` setting has been reinstated with revised semantics. This setting was
-removed in [#4427](https://github.com/astral-sh/ruff/pull/4427), as it was equivalent to ignoring
-the `UP006` and `UP007` rules via Ruff's standard `ignore` mechanism.
-
-Taking `UP006` (rewrite `List[int]` to `list[int]`) as an example, the setting now behaves as
-follows:
-
-- On Python 3.7 and Python 3.8, setting `keep-runtime-typing = true` will cause Ruff to ignore
-    `UP006` violations, even if `from __future__ import annotations` is present in the file.
-    While such annotations are valid in Python 3.7 and Python 3.8 when combined with
-    `from __future__ import annotations`, they aren't supported by libraries like Pydantic and
-    FastAPI, which rely on runtime type checking.
-- On Python 3.9 and above, the setting has no effect, as `list[int]` is a valid type annotation,
-    and libraries like Pydantic and FastAPI support it without issue.
-
-In short: `keep-runtime-typing` can be used to ensure that Ruff doesn't introduce type annotations
-that are not supported at runtime by the current Python version, which are unsupported by libraries
-like Pydantic and FastAPI.
-
-Note that this is not a breaking change, but is included here to complement the previous removal
-of `keep-runtime-typing`.
-
-## 0.0.268
-
-### The `keep-runtime-typing` setting has been removed ([#4427](https://github.com/astral-sh/ruff/pull/4427))
-
-Enabling the `keep-runtime-typing` option, located under the `pyupgrade` section, is equivalent
-to ignoring the `UP006` and `UP007` rules via Ruff's standard `ignore` mechanism. As there's no
-need for a dedicated setting to disable these rules, the `keep-runtime-typing` option has been
-removed.

-### `update-check` is no longer a valid configuration option ([#4313](https://github.com/astral-sh/ruff/pull/4313))
-
-The `update-check` functionality was deprecated in [#2530](https://github.com/astral-sh/ruff/pull/2530),
-in that the behavior itself was removed, and Ruff was changed to warn when that option was enabled.
-
-Now, Ruff will throw an error when `update-check` is provided via a configuration file (e.g.,
-`update-check = false`) or through the command-line, since it has no effect. Users should remove
-this option from their configuration.

-### `--fix-only` now exits with a zero exit code, unless `--exit-non-zero-on-fix` is specified ([#4146](https://github.com/astral-sh/ruff/pull/4146))
-
-Previously, `--fix-only` would exit with a non-zero exit code if any fixes were applied. This
-behavior was inconsistent with `--fix`, and further, meant that `--exit-non-zero-on-fix` was
-effectively ignored when `--fix-only` was specified.
-
-Now, `--fix-only` will exit with a zero exit code, unless `--exit-non-zero-on-fix` is specified,
-in which case it will exit with a non-zero exit code if any fixes were applied.
-
-## 0.0.260
-
-### Fixes are now represented as a list of edits ([#3709](https://github.com/astral-sh/ruff/pull/3709))
-
-Previously, Ruff represented each fix as a single edit, which prohibited Ruff from automatically
-fixing violations that required multiple edits across a file. As such, Ruff now represents each
-fix as a list of edits.
-
-This primarily affects the JSON API. Ruff's JSON representation used to represent the `fix` field as
-a single edit, like so:
-
-```json
-{
-    "message": "Remove unused import: `sys`",
-    "content": "",
-    "location": {"row": 1, "column": 0},

-
-The updated representation instead includes a list of edits:

+# flake8-to-ruff
+
+Convert existing Flake8 configuration files (`setup.cfg`, `tox.ini`, or `.flake8`) for use with
+[Ruff](https://github.com/charliermarsh/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 [Ruff README](https://github.com/charliermarsh/ruff#user-content-how-does-ruff-compare-to-flake8)
+   for the complete list of supported plugins.)

-        //     certainly makes it harder to catch these issues in our user code.

-/// 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

-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).

-/// 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)

-[![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.
