Charlie Marsh 1044d66c1c Add support for PatternMatchMapping formatting (#6836) ... <!-- Thank you for contributing to Ruff! To help us out with reviewing, please consider the following: - Does this pull request include a summary of the change? (See below.) - Does this pull request include a descriptive title? - Does this pull request include references to any relevant issues? --> ## Summary Adds support for `PatternMatchMapping` -- i.e., cases like: ```python match foo: case {"a": 1, "b": 2, **rest}: pass ``` Unfortunately, this node has _three_ kinds of dangling comments: ```python { # "open parenthesis comment" key: pattern, ** # end-of-line "double star comment" # own-line "double star comment" rest # end-of-line "after rest comment" # own-line "after rest comment" } ``` Some of the complexity comes from the fact that in `**rest`, `rest` is an _identifier_, not a node, so we have to handle comments _after_ it as dangling on the enclosing node, rather than trailing on `**rest`. (We could change the AST to use `PatternMatchAs` there, which would be more permissive than the grammar but not totally crazy -- `PatternMatchAs` is used elsewhere to mean "a single identifier".) Closes https://github.com/astral-sh/ruff/issues/6644. ## Test Plan `cargo test`		2023-08-25 04:33:34 +00:00
