tytr

Type transformations for Python.

Create types from class definitions.

Create tests to keep those types up to date.

Type creation

# foo.py
class Foo:
    a: int
    b: float

A TypedDict based on Foo:

$ tytr gen typeddict foo.py::Foo --name FooDict

# Generated by tytr gen typeddict
from __future__ import annotations
from typing_extensions import TypedDict

class FooDict(TypedDict):
    a: int
    b: float

A protocol for a getter for Foo:

$ tytr gen getter foo.py::Foo --name GetFoo

# Generated by tytr gen getter
from __future__ import annotations
from typing import Literal, Protocol, overload

class GetFoo(Protocol):
    @overload
    def __call__(self, key: Literal["a"]) -> int: ...

    @overload
    def __call__(self, key: Literal["b"]) -> float: ...

... and many more
