barbara 2.3.0

Environment variable management

Environment variable management

New in 2.0!

• Features have been dropped: - Legacy templates aren’t supported anymore - Subvariables aren’t supported anymore - SSM support has been dropped, as there are better ways to do this

• Schema-version has been added to document schema to make it easier for me to deprecate and change the schema if necessary

Installation

$ pip install barbara

Usage

YAML Format (.env.yml)

1. Create an .env.yml for your project

Why barbara?

Because Barbara Liskov created the Liskov Substitution Principle and is a prolific contributor to computer science and software engineering. Barbara is one of the Newton’s metaphorical giants that enables us to see further. I humbly dedicate my project to her and her contributions and offer this project to its consumers with a license befitting that dedication.
