Version 0.1.1

Typed environment variable parsing for Python

Background

Typenv does environment variable parsing with an API almost identical to the excellent environs. There are a few reasons why typenv might be preferred:

• Type annotated typecast functions: type checkers are able to understand types of parsed environment variables.
• More flexible prefix manipulation of environment variable names.
• Validation of environment variable names.
• Optional automatic uppercasing of environment variable names.
• Ability to generate a .env.example that shows expected types of environment variables.
• Less dependencies. No marshmallow required.

Installing

Installing from PyPI repository (https://pypi.org/project/typenv):

pip install typenv

Usage

See environs README.md for now, as the API of typenv is mostly just a subset of environs'.

The types supported by typenv are:

• env.str
• env.int
• env.bool
• env.float
• env.decimal
• env.json
• env.list
  • Takes a subcast argument for casting list items to one of str, int , bool, float or decimal.Decimal

TODO: Add a more comprehensive API documentation / usage guide here.

Acknowledgments

The public API of this library is almost an exact copy of environs, which is based on envparse and django-environ. Credit for the interface goes to the authors of those libraries.
