Overview

checksignature

a function decorator for enforcing function signatures

Setup

Ensure nox is installed.

pip install nox

Run nox to build, install, and run checksignature tests.

Usage

Decorate any funciton with @checksignature.

@checksignature
def function(a: str, b: int, c, **kwargs):
    return a, b, c, kwargs

Upon invocation of function, the signature check is evaluated.

function('one', 2, 3.0, **{'four': 4})  #=> functions as usual--no problem.
function(1, 2, 3.0, **{'four': 4})      #=> raises a TypeError
