Craftsperson Environment

What is it?

craftsperson_env reads configuration files in yaml, env, toml, xml, and json formats and adds them to the 'os.environ' system. It formats the keys according to naming-case-type, upper or lower, and arranges them with a specific join type in the upper-lower section. Additionally, it specifies the data type when retrieving data from 'os.environ' to access data of that type.

Where to get it

You can access the Github repository from here.

Pip installers for the latest released version are available at the Python Package Index (PyPI)

Installation

python setup.py install

pip install craftsperson-env

Get the Value From the 'os.environ' System

Description

Help on function get in module craftsperson_env.__main__:

get(key: str, value_type: Any = <class 'str'>, default: Any = None) -> str
    This function retrieves the value associated with the key from the 'os.environ' system.
    
    Parameters
    ----------
    key: str
        This parameter retrieves the key from the 'os.environ' system.
    value_type: str, optional.
        This parameter accepts value types such as int, str, list, dict, and others. The default value is str.
    default: Any, optional.
