med1844	7982edac90	[ty] Add support for @staticmethods (#18809) ... ## Summary Add support for `@staticmethod`s. Overall, the changes are very similar to #16305. #18587 will be dependent on this PR for a potential fix of https://github.com/astral-sh/ty/issues/207. mypy_primer will look bad since the new code allows ty to check more code. ## Test Plan Added new markdown tests. Please comment if there's any missing tests that I should add in, thank you.	2025-06-20 10:38:17 +02:00
Dhruv Manilawala	22177e6915	[ty] Surface matched overload diagnostic directly (#18452) ... ## Summary This PR resolves the way diagnostics are reported for an invalid call to an overloaded function. If any of the steps in the overload call evaluation algorithm yields a matching overload but it's type checking that failed, the `no-matching-overload` diagnostic is incorrect because there is a matching overload, it's the arguments passed that are invalid as per the signature. So, this PR improves that by surfacing the diagnostics on the matching overload directly. It also provides additional context, specifically the matching overload where this error occurred and other non-matching overloads. Consider the following example: ```py from typing import overload @overload def f() -> None: ... @overload def f(x: int) -> int: ... @overload def f(x: int, y: int) -> int: ... def f(x: int | None = None, y: int | None = None) -> int | None: return None f("a") ``` We get: <img width="857" alt="Screenshot 2025-06-18 at 11 07 10" src="https://github.com/user-attachments/assets/8dbcaf13-2a74-4661-aa94-1225c9402ea6" /> ## Test Plan Update test cases, resolve existing todos and validate the updated snapshots.	2025-06-20 08:36:49 +05:30
Shunsuke Shibayama	0858896bc4	[ty] type narrowing by attribute/subscript assignments (#18041) ... ## Summary This PR partially solves https://github.com/astral-sh/ty/issues/164 (derived from #17643). Currently, the definitions we manage are limited to those for simple name (symbol) targets, but we expand this to track definitions for attribute and subscript targets as well. This was originally planned as part of the work in #17643, but the changes are significant, so I made it a separate PR. After merging this PR, I will reflect this changes in #17643. There is still some incomplete work remaining, but the basic features have been implemented, so I am publishing it as a draft PR. Here is the TODO list (there may be more to come): * [x] Complete rewrite and refactoring of documentation (removing `Symbol` and replacing it with `Place`) * [x] More thorough testing * [x] Consolidation of duplicated code (maybe we can consolidate the handling related to name, attribute, and subscript) This PR replaces the current `Symbol` API with the `Place` API, which is a concept that includes attributes and subscripts (the term is borrowed from Rust). ## Test Plan `mdtest/narrow/assignment.md` is added. --------- Co-authored-by: David Peter <sharkdp@users.noreply.github.com> Co-authored-by: Carl Meyer <carl@astral.sh>	2025-06-04 17:24:27 -07:00
