setmeup

Installation

$ pip install setmeup

Usage

setmeup.from_env is a decorator that takes a class and overrides its fields with data from environment variables. That's pretty much all API.

import setmeup

# Define default settings
@setmeup.from_env
class Config:
    DEBUG = False
    PORT = 3000
    APP_ENV = "dev"
    ENABLE_HALLUCINATIONS = True

# Just use Config's fields
print(Config.DEBUG)
print(Config.PORT)

You can override any parameter via environment variable. For example, setting PORT=8080 before running the app sets Config.PORT to integer 8080. setmeup tries to use the same type as default value.

Usage with Flask

Since it's all about plain objects, you can easily use setmeup to populate Flask config:

import Config from yoursettings

app.config.from_object(Config)
