Dhruv Manilawala dbd84c947b Formatter parentheses support for IpyEscapeCommand (#8207) ... ## Summary This PR removes the `todo!()` around `IpyEscapeCommand` in the formatter. The `NeedsParentheses` trait needs to be implemented which always return `Never`. The reason being that if an escape command is parenthesized, then that's not parsed as an escape command. IOW, the parentheses shouldn't be present around an escape command. In the similar way, the `CanSkipOptionalParenthesesVisitor` will skip this node. ## Test Plan Updated the `unformatted.ipynb` fixture with new cells containing IPython escape commands and the corresponding snapshot was verified. Also, tested it out in a few open source repositories containing notebooks (`openai/openai-cookbook`, `huggingface/notebooks`). #### New cells in `unformatted.ipynb` **Cell 2** ```markdown A markdown cell ``` **Cell 3** ```python def some_function(foo, bar): pass %matplotlib inline ``` **Cell 4** ```python foo = %pwd def some_function(foo,bar,): foo = %pwd print(foo ) ``` fixes: #8204		2023-10-25 14:01:50 +00:00
