Ruff doesn't catch undefined argument to function

Question

I'm not sure even if it is ruff's job to catch the undefined argument to a function, but is there a tool that does this? or is there a ruff configuration that I'm missing to add so that ruff can do this?

from typing import Optional


def my_func(bar: int, baz: int, foo: Optional[int] = None) -> int:
    if foo:
        return foo + bar + baz
    else:
        return bar + baz


my_func(foo=1, bar=2, baz=3)
my_func(bar=2, baz=3)
my_func(f=1, bar=2, baz=3) # this should have been caught by ruff, but isn't and I'm

Answer 1

Ruff does not currently support this. Quoting the Ruff FAQ:

Pylint implements many rules that Ruff does not, and vice versa. For example, Pylint does more type inference than Ruff (e.g., Pylint can validate the number of arguments in a function call). As such, Ruff is not a "pure" drop-in replacement for Pylint (and vice versa), as they enforce different sets of rules.

Despite these differences, many users have successfully switched from Pylint to Ruff, especially those using Ruff alongside a type checker, which can cover some of the functionality that Pylint provides.
