Argumentize decorator allow convert any function into kind a 'pure' function that eliminate all globals and closures as a implicit dependencies but allow them to be passed as regular key-value arguments.

Here is a simple example:

from argumentize import argumentize

x = 100


def foo(a, b, c):
    return a + b + c + x


foo = argumentize(foo)

foo(1, 2, 3)  # 106
foo(1, 2, 3, x=10)  # 16

Argumentized can be any dependency not only a variable. Here is how you can use it with a function:

from argumentize import argumentize


def foo(a, b, c):
    return a + b + c


def bar(a, b, c, d):
    return foo(a, b, c) + d


bar = argumentize(bar)

bar(1, 2, 3, 4)  # 10

bar(1, 2, 3, 4, foo=lambda a, b, c: a * b * c)  # 24

Argumentize can be used as a decorator:

from argumentize import argumentize


@argumentize
def foo(a, b, c):
    return a + b + c


foo(1, 2, 3)  # 6

foo(1, 2, 3, b=10)  # 14

If you does not provide the value for argumented argument the default variable (either from globals or from the function closure) will be used

How to deploy

We use setup.py and setup.cfg to deploy the package to PyPI. To create a source distribution and upload it to PyPI, run the following commands:

python setup.py sdist

Install twine if you haven't already:

pip install twine

Then upload the package to PyPI:

twine upload dist/*
