[ty] Support `Unpack[TypedDict]` by charliermarsh · Pull Request #24653 · astral-sh/ruff

charliermarsh · 2026-04-15T13:30:09Z

Summary

We now support Unpack[TypedDict] as an annotation on **kwargs, as in the following example:

from typing_extensions import TypedDict, Unpack

class MovieKwargs(TypedDict):
    title: str
    year: int

def show_movie(**kwargs: Unpack[MovieKwargs]) -> None:
    ...

show_movie(title="Alien", year=1979)  # OK
show_movie(title="Alien")             # missing required key
show_movie(name="Alien", year=1979)   # unknown keyword

Typing conformance results improved 🎉

The percentage of diagnostics emitted that were expected errors increased from 87.94% to 88.34%. The percentage of expected errors that received a diagnostic increased from 83.36% to 84.42%. The number of fully passing files improved from 79/133 to 81/133.

Summary

How are test cases classified?

Each test case represents one expected error annotation or a group of annotations sharing a tag. Counts are per test case, not per diagnostic — multiple diagnostics on the same line count as one. Required annotations (E) are true positives when ty flags the expected location and false negatives when it does not. Optional annotations (E?) are true positives when flagged but true negatives (not false negatives) when not. Tagged annotations (E[tag]) require ty to flag exactly one of the tagged lines; tagged multi-annotations (E[tag+]) allow any number up to the tag count. Flagging unexpected locations counts as a false positive.

This lets us distinguish **kwargs: Unpack[TD] from **kwargs: TD. The latter means that every kwarg value is itself of type TD.

Slightly annoying because we already have some logic for extracting these keys in the more general case (see, e.g., extract_unpacked_typed_dict_keys_from_value_type), but PEP 692 explicitly forbids unions.

This is necessary for cases like...

class MaybeX(TypedDict, total=False): x: str def takes_x(*, x: int) -> None: ... takes_x(**maybe_x)

Where we need to report both missing-argument and invalid-argument-type.

charliermarsh · 2026-04-15T15:57:06Z

For the ecosystem report...

I believe the graphql-core diagnostics are true positives? They're unpacking with a TypedDict(total=False), although according to Codex other type checkers don't raise these errors, i.e., they don't require that the key is definitely present. I prefer our behavior but it is stricter.
For bokeh, there are generally a lot of TypedDict usages in that codebase that type checkers can't model (e.g., calls on an event type that then need to narrow the return type, etc.), so I'm not overly concerned.

Based on Codex's analysis, the rest are either true positives or things that are sufficiently dynamic that we shouldn't really expect to model them. But I'll go through a few more on my own.

charliermarsh · 2026-04-15T16:05:43Z

Also, note that the newly-added false positive on the conformance tests is related to extra_items, which we don't yet support.

+## `Unpack[TypedDict]` in `**kwargs`
+
+Using `Unpack[TypedDict]` on a `**kwargs` parameter should expose the `TypedDict` shape both inside


I haven't read the mdtest but could we split this test into multiple smaller snippets with some prose between snippets explaining what's being tested and what the expected behavior is?

This is one of my main learnings from maintaining Ruff. The long fixture files are a pain to maintain over time because they lack context of why something has been tested in the first place and if it's even asserting something intentionally or if they just tried to be exhaustive.
