enviscerate 0.0.1

Access env variables by one line declaration with automatic typecasting

ENViscerate

One line access to environment variables, handling typecasts automatically. Simply declare a variable with the same name, assigning it to the output of the function env(default_value) where default_value is of the type you want the env variable casted as. It is easier to say with an example

from enviscerate import env
HOME = env('/this/dir')

Will set the value of HOME with the following precedence

1. env var $HOME
2. .env file supplied value
3. value '/this/dir' you supplied to env() function above

features

• if type is dict, it will be parsed as JSLOB using jsonofabitch module(if available). parsed as JSON using builtin json.loads() otherwise
• if bool it will be set to True if str(val).lower() in ["t", "true", "1", "yes", "y"] for env(val) and False otherwise
• If None, the case of env(), you will get None if the variable is not declared and a string otherwise
• otherwise it will be casted as whatever you supply. presumably an int float or str but with no presumptions or restrictions thereof
• It will use dotenv if available but does not require it, but will spit warnings to avoid frustrating mysterious why-are-my-settings-not-registering hickups
