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.

https://travis-ci.org/nkantar/Parsenvy.svg?branch=master https://ci.appveyor.com/api/projects/status/ypywtakntwsf6l00/branch/master?svg=true

Features

  • Compatible with Python 3.6+ only (the last Python 2 compatible version was 1.0.2)
  • Fully tested on Linux and Windows
  • No dependencies aside from Python's core builtins, os, and typing modules
  • BSD (3-Clause) licensed

Examples

>>> import parsenvy
>>> parsenvy.bool('BOOL_ENV_VAR')  # BOOL_ENV_VAR=True
True
>>> parsenvy.int('INT_ENV_VAR')  # INT_ENV_VAR=13
13
>>> parsenvy.float('FLOAT_ENV_VAR')  # FLOAT_ENV_VAR=555.55
555.55
>>> parsenvy.list('LIST_ENV_VAR')  # LIST_ENV_VAR=shiver,me,timbers
['shiver', 'me', 'timbers']
>>> parsenvy.tuple('TUPLE_ENV_VAR')  # TUPLE_ENV_VAR=hello,world
('hello', 'world')
>>> parsenvy.str('STR_ENV_VAR')  # STR_ENV_VAR=meep
'meep'
>>> parsenvy.set('SET_ENV_VAR')  # SET_ENV_VAR=wat,wut,wot
set(['wat', 'wut', 'wot'])

# Note: Version 3 will deprecate parsenvy.dict().
>>> parsenvy.dict('DICT_ENV_VAR')  # DICT_ENV_VAR=a:1,b:2
{'a': '1', 'b': '2'}
