Smart tiny config library for flask-like config

How to install

pip install design-config

You can find source code of library on GitHub

How to use

import os
from design_config import DesignConfig, D, ___

class Config(DesignConfig):

    """ is D("") """
    PROP_ZERO = ___
    
    """ is 'hello' """
    PROP_ONE = 'Hello'

    """ 'World' if in init_data_dict not PROP_TWO
    As usually init_data_dict is os.environ """
    PROP_TWO = D('World')

    """ 'Hello World!' or 'hello {PROP_TWO}!' for any PROP_TWO """
    PROP_THREE = '{PROP_ONE} {PROP_TWO}!'


config = Config()

If your global environment variables contain $PROP_TWO , it will be replaced in the config with the appropriate value. Otherwise, it will remain by default (World)

D means "default"

config.PROP_THREE # "Hello World!"

config['PROP_THREE'] # "Hello World!"
config['{PROP_THREE}!!'] # "Hello World!!!"
config['{PROP_FOUR}'] # "PROP_FOUR"

config('{PROP_ONE} Tom') # "Hello Tom"
config('PROP_FOUR', 'London') # "London"
config('PROP_TWO', 'London') # "World"
config('{PROP_ZERO}', 'London') # ""
config('{PROP_FOUR}', 'London') # "PROP_FOUR"

Also you can use int, bool, and float values:

class Config(DesignConfig):

    PROP_FIVE = D(55)

    PROP_SIX = D(True)

    PROP_SEVEN = D(7.7)

config = Config({
    'PROP_FIVE': '5', 
    'PROP_SIX': 'FALSE',
    'PROP_SEVEN': '7e7'
})

config.PROP_FIVE # 5
config.PROP_SIX # False
config.PROP_SEVEN # 7e7

You can use DesignConfig with Flask like that:

class MyFlaskConfig(DesignConfig):

    VERSION = '2'

    FLASK_DEBUG = D(True)
    IS_PRODUCTION = D(False)
    DEBUG = D(True)

    PROJECT_PATH = D('/base')

    REDIS_HOST = D('localhost')
    REDIS_PORT = D('6379')

    """..."""

config = MyFlaskConfig()

my_flask_app = Flask(__name__, static_folder='static', static_url_path='')
my_flask_app.config.from_object(config)
