pollute

A decorator and context manager for temporarily modifying os.environ.

# as a context manager
with modified_environ(added={...}, absent=[...]):
    ...

# as a decorator
@modified_environ(added={...}, absent=[...])

Installation:

$ pip install pollute

modified_environ modifies os.environ in-place, ensuring that all references to it in the code are updated. All changes made by modified_environ are reversed when exiting the context or decorator.

Example

import os
from pollute import modified_environ


assert 'HELLO' not in os.environ
assert 'PATH' in os.environ

with modified_environ(added={'HELLO': 'WORLD'}, absent=['PATH']):
    assert os.environ['HELLO'] == 'WORLD'
    assert 'PATH' not in os.environ

assert 'HELLO' not in os.environ
assert 'PATH' in os.environ
