Project description

Parsenvy is an enviously elegant environment variable parsing Python library.

main Documentation Status Github Actions badgefury svg Unreleased chages License: BSD-3-Clause

Environment variables are strings by default. This can be rather inconvenient if you’re dealing with a number of them, and in a variety of desired types. Parsenvy aims to provide an intuitive, explicit interface for retrieving these values in appropriate types with human-friendly syntax.


  • Compatible with Python 3.6+ only (the last Python 2 compatible version was 1.0.2).

  • Fully tested on Linux, macOS, and Windows.

  • No dependencies outside of the Python standard library.

  • BSD (3-Clause) licensed.

  • Utterly awesome.

  • Now with docs!


>>> import parsenvy

>>> parsenvy.bool('DEBUG_ENABLED')  # DEBUG_ENABLED=True


>>> parsenvy.float('EXCHANGE_RATE')  # EXCHANGE_RATE=42.911

>>> parsenvy.list('INVALID_USERNAMES')  # INVALID_USERNAMES=admin,superuser,user,webmaster
['admin', 'superuser', 'user', 'webmaster']

>>> parsenvy.tuple('SAMPLE_GREETING')  # SAMPLE_GREETING=Hello,world!
('Hello', 'world!')

>>> parsenvy.set('ALLOWED_CATEGORIES')  # ALLOWED_CATEGORIES=python,vim,git
{'python', 'vim', 'git'}

>>> parsenvy.str('DB_PREFIX')  # DB_PREFIX=dj_


pip install parsenvy
