Implement PYI030: Unnecessary literal union #5570

zanieb · 2023-07-06T19:00:46Z

Implements PYI030 as part of #848

Union expressions should never have more than one Literal member, as Literal[1] | Literal[2] is semantically identical to Literal[1, 2].

Note we differ slightly from the flake8-pyi implementation:

We detect cases where there are parentheses or nested unions
We detect cases with mixed Union and | syntax
We use the same error message for all violations; flake8-pyi has two different messages
We retain the user's quoting style when displaying string literals; flake8-pyi uses single quotes
We warn on duplicates of the same literal Literal[1] | Literal[1]
- flake8-pyi does not warn on this because it overlaps with PYI016; we can avoid a violation here if we want but then we'll need to track the hashes of all seen literals alongside the vector of literal expressions which I would prefer to keep ordered

We may want to add these (&& self.semantic.in_type_definition()) to the Rule::UnnecessaryLiteralUnion condition too. I can't quite remember why they're necessary here. I'm guessing it's because for |, if it's used outside of a type definition, it's not a union operator (it's a bitwise or, I think).

That's true for the DuplicateUnionMember rule where they're checking for any duplicate items in a | but here we know we are constrained to literal types where this does apply.

We test for this at

https://github.com/charliermarsh/ruff/blob/1759d914456b62dfc479518ce8717949935f6c87/crates/ruff/resources/test/fixtures/flake8_pyi/PYI030.pyi#L28

You can see that a bitwise or of literals resolve to a Union outside of an annotation:

In [3]: Literal[1] | Literal[2] Out[3]: typing.Union[typing.Literal[1], typing.Literal[2]] In [4]: x = Literal[1] | Literal[2] In [5]: x Out[5]: typing.Union[typing.Literal[1], typing.Literal[2]]

I guess it's possible that someone has Literal[1] | bar | Literal[2] where bar implements some sort of custom bitwise or behavior and this rule no longer holds but I'm not sure that's worth handling

Interesting, that makes sense. Thanks for the thorough follow-up!

Note we could implement auto-fix for this but it seems painful given the enumerated edge-cases in the test file. We can pursue it at a later time if requested.

To opt-in to linting Jupyter Notebook files, add the `*.ipynb` pattern to your [`include`](settings.md#include) setting, like so: ```toml [tool.ruff] ### Allow Ruff to discover `*.ipynb` files. include = ["*.py", "*.pyi", "**/pyproject.toml", "*.ipynb"] ``` This will prompt Ruff to discover Jupyter Notebook files in any specified directories, and lint them accordingly. Jupyter Notebook support is currently opt-in and experimental. We'd love your help testing it out. Have feedback? Run into issues?
