This PR pins black to the latest release 24.2.0.

Changelog

### 24.2.0 ``` Stable style - Fixed a bug where comments where mistakenly removed along with redundant parentheses (4218) Preview style - Move the `hug_parens_with_braces_and_square_brackets` feature to the unstable style due to an outstanding crash and proposed formatting tweaks (4198) - Fixed a bug where base expressions caused inconsistent formatting of \*\* in tenary expression (4154) - Checking for newline before adding one on docstring that is almost at the line limit (4185) - Remove redundant parentheses in `case` statement `if` guards (4214). Configuration - Fix issue where _Black_ would ignore input files in the presence of symlinks (4222) - _Black_ now ignores `pyproject.toml` that is missing a `tool.black` section when discovering project root and configuration. Since _Black_ continues to use version control as an indicator of project root, this is expected to primarily change behavior for users in a monorepo setup (desirably). If you wish to preserve previous behavior, simply add an empty `[tool.black]` to the previously discovered `pyproject.toml` (4204) Output - Black will swallow any `SyntaxWarning`s or `DeprecationWarning`s produced by the `ast` module when performing equivalence checks (4189) Integrations - Add a JSONSchema and provide a validate-pyproject entry-point (4181) ``` ### 24.1.1 ``` Bugfix release to fix a bug that made Black unusable on certain file systems with strict limits on path length. Preview style - Consistently add trailing comma on typed parameters (4164) Configuration - Shorten the length of the name of the cache file to fix crashes on file systems that do not support long paths (4176) ``` ### 24.1.0 ``` Highlights This release introduces the new 2024 stable style (4106), stabilizing the following changes: - Add parentheses around `if`-`else` expressions (2278) - Dummy class and function implementations consisting only of `...` are formatted more compactly (3796) - If an assignment statement is too long, we now prefer splitting on the right-hand side (3368) - Hex codes in Unicode escape sequences are now standardized to lowercase (2916) - Allow empty first lines at the beginning of most blocks (3967, 4061) - Add parentheses around long type annotations (3899) - Enforce newline after module docstrings (3932, 4028) - Fix incorrect magic trailing comma handling in return types (3916) - Remove blank lines before class docstrings (3692) - Wrap multiple context managers in parentheses if combined in a single `with` statement (3489) - Fix bug in line length calculations for power operations (3942) - Add trailing commas to collection literals even if there's a comment after the last entry (3393) - When using `--skip-magic-trailing-comma` or `-C`, trailing commas are stripped from subscript expressions with more than 1 element (3209) - Add extra blank lines in stubs in a few cases (3564, 3862) - Accept raw strings as docstrings (3947) - Split long lines in case blocks (4024) - Stop removing spaces from walrus operators within subscripts (3823) - Fix incorrect formatting of certain async statements (3609) - Allow combining ` fmt: skip` with other comments (3959) There are already a few improvements in the `--preview` style, which are slated for the 2025 stable style. Try them out and [share your feedback](https://github.com/psf/black/issues). In the past, the preview style has included some features that we were not able to stabilize. This year, we're adding a separate `--unstable` style for features with known problems. Now, the `--preview` style only includes features that we actually expect to make it into next year's stable style. Stable style Several bug fixes were made in features that are moved to the stable style in this release: - Fix comment handling when parenthesising conditional expressions (4134) - Fix bug where spaces were not added around parenthesized walruses in subscripts, unlike other binary operators (4109) - Remove empty lines before docstrings in async functions (4132) - Address a missing case in the change to allow empty lines at the beginning of all blocks, except immediately before a docstring (4130) - For stubs, fix logic to enforce empty line after nested classes with bodies (4141) Preview style - Add `--unstable` style, covering preview features that have known problems that would block them from going into the stable style. Also add the `--enable-unstable-feature` flag; for example, use `--enable-unstable-feature hug_parens_with_braces_and_square_brackets` to apply this preview feature throughout 2024, even if a later Black release downgrades the feature to unstable (4096) - Format module docstrings the same as class and function docstrings (4095) - Fix crash when using a walrus in a dictionary (4155) - Fix unnecessary parentheses when wrapping long dicts (4135) - Stop normalizing spaces before ` fmt: skip` comments (4146) Configuration - Print warning when configuration in `pyproject.toml` contains an invalid key (4165) - Fix symlink handling, properly ignoring symlinks that point outside of root (4161) - Fix cache mtime logic that resulted in false positive cache hits (4128) - Remove the long-deprecated `--experimental-string-processing` flag. This feature can currently be enabled with `--preview --enable-unstable-feature string_processing`. (4096) Integrations - Revert the change to run Black's pre-commit integration only on specific git hooks (3940) for better compatibility with older versions of pre-commit (4137) Thank you Thank you to everyone who provided feedback to help make Black's 2024 style even better. Thank you also to everyone who contributed code to Black. ``` ### 24.1a1 ``` This is a preview of the 2024 stable style, showing the formatting that Black will use in 2024. Please test it out and [share your feedback](https://github.com/psf/black/issues/4042). This applies the following changes: - Multiline strings passed as the sole function arguments are formatted more compactly (1879) - Dummy class and function implementations consisting only of `...` are formatted more compactly (3796) - If an assignment statement is too long, we now prefer splitting on the right-hand side (3368) - Hex codes in Unicode escape sequences are now standardized to lowercase (2916) - Allow empty first lines at the beginning of most blocks (3967, 4061) - Add parentheses around long type annotations (3899) - Standardize on a single newline after module docstrings (3932) - Fix incorrect magic trailing comma handling in return types (3916) - Remove blank lines before class docstrings (3692) - Wrap multiple context managers in parentheses if combined in a single `with` statement (3489) - Fix bug in line length calculations for power operations (3942) - Add trailing commas to collection literals even if there's a comment after the last entry (3393) - When using `--skip-magic-trailing-comma` or `-C`, trailing commas are stripped from subscript expressions with more than 1 element (3209) - Add extra blank lines in stubs in a few cases (3564, 3862) - Accept raw strings as docstrings (3947) - Split long lines in case blocks (4024) - Stop removing spaces from walrus operators within subscripts (3823) - Fix incorrect formatting of certain async statements (3609) - Allow combining ` fmt: skip` with other comments (3959) The following two changes may be included, but have outstanding issues that will need to be resolved: - Long values in dict literals are now wrapped in parentheses; correspondingly unnecessary parentheses around short values in dict literals are now removed; long string lambda values are now wrapped in parentheses (3440) - Add parentheses around `if`-`else` expressions (2278) ``` ### 23.12.1 ``` Fixed a bug that included dependencies from the d extra by default (4108) ``` ### 23.12.0 ``` Highlights It's almost 2024, which means it's time for a new edition of _Black_'s stable style! Together with this release, we'll put out an alpha release 24.1a1 showcasing the draft 2024 stable style, which we'll finalize in the January release. Please try it out and [share your feedback](https://github.com/psf/black/issues/4042). This release (23.12.0) will still produce the 2023 style. Most but not all of the changes in `--preview` mode will be in the 2024 stable style. Stable style - Fix bug where ` fmt: off` automatically dedents when used with the `--line-ranges` option, even when it is not within the specified line range.

These issues have now been fixed, and this release should come with compiled wheels once again. There will be no wheels for Python 3.12 due to a bug in mypyc. We will provide 3.12 wheels in a future release as soon as the mypyc bug is fixed.

(3166) - `--skip-string-normalization` / `-S` now prevents docstring prefixes from being normalized as expected (3168) - When using `--skip-magic-trailing-comma` or `-C`, trailing commas are stripped from subscript expressions with more than 1 element (3209) - Implicitly concatenated strings inside a list, set, or tuple are now wrapped inside parentheses (3162) - Fix a string merging/split issue when a comment is present in the middle of implicitly concatenated strings on its own line (3227) _Blackd_ - `blackd` now supports enabling the preview style via the `X-Preview` header (3217) Configuration - Black now uses the presence of debug f-strings to detect target version (3215) - Fix misdetection of project root and verbose logging of sources in cases involving `--stdin-filename` (3216) - Immediate `.gitignore` files in source directories given on the command line are now also respected, previously only `.gitignore` files in the project root and automatically discovered directories were respected (3237) Documentation - Recommend using BlackConnect in IntelliJ IDEs (3150) Integrations - Vim plugin: prefix messages with `Black: ` so it's clear they come from Black (3194) - Docker: changed to a /opt/venv installation + added to PATH to be available to non-root users (3202) Output - Change from deprecated `asyncio.get_event_loop()` to create our event loop which removes DeprecationWarning (3164) - Remove logging from internal `blib2to3` library since it regularly emits error logs about failed caching that can and should be ignored (3193) Parser - Type comments are now included in the AST equivalence check consistently so accidental deletion raises an error. Though type comments can't be tracked when running on PyPy 3.7 due to standard library limitations.
