Parsenvy: Enviously Elegant Environment Variable Parsing

Parsenvy is an enviously elegant environment variable parsing Python library.

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.

Features

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!

Examples

>>> import parsenvy

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

>>> parsenvy.int('POSTS_PER_PAGE')  # POSTS_PER_PAGE=13
13

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