Yaml Settings Configuration Module

A Yaml Settings Configuration Module.

A library to help manage project settings, without having to worry about accidentally checking non-public information, like api keys. Along with simple environment variable support.

Example setup

Python Code - Base Functions:

app_settings = load('defaults.yml')
update_from_env(test_settings)
update_from_file(app_defaults, 'settings.yml')
user = app_settings.myproj.databases.primary_sql.user

Python Code - YamlSettings Helper Class:

project_settings = YamlSettings('defaults.yml',
                                'settings.yml',
                                default_section='myproj')
base_settings = project_settings.get_settings()
user = base_settings.databases.primary_sql.user

# Program Defaults, do not edit this file!!!
# All values should be overridden in the following ways:
# 1. In the 'settings.yaml' file.
# 2. With environment variables. Example myproj.databases.primary_sql.user can
#    be overridden with MYPROJ_DATABASES_PRIMARY_SQL_USER.
