pytailor

Set up configuration for your application or library with ease.

Features

pytailor gives you a few key features that make your life easy when creating libraries or applications:

Easily create configuration following the config.py pattern
Use environment variables in your configuration and change them dynamically at runtime
Use a .env file and follow the twelve-factor app methodology

Example

Get up and running with full configuration quickly:

from pytailor import Tailor

class Config(object):
    DEBUG = False

config = Tailor()
# load from a simple object
config.from_object(Config)
# add and watch environment variables
config.from_envar("DEBUG")
# use a dotenv file
config.from_dotenv("/path/to/.env/")
# config works like a dict!
config["DEBUG"] # True

Installation

Installation is easy using pip:

pip install pytailor

Advanced Usage

Usage with pipenv

If your using a dev workflow tool like Pipenv, you can easily pair pytailor with it. Pipenv will automatically load .env files for you out of the box. To track variables loaded from a .env file when using Pipenv, simply use this pattern:

# .env file
DEBUG=true

from pytailor import Tailor
config = Tailor()
# watch each variable loaded by Pipenv
config.from_envar("DEBUG")
config["DEBUG"]  # True

Usage with python-dotenv

python-dotenv is a useful tool for managing .env files in multiple environments. As with the previous example, it's easy to pair with pytailor.

# .env file
DEBUG=true

from dotenv import load_dotenv
from pytailor import Tailor

load_dotenv()
config = Tailor()
# watch each variable loaded by python-dotenv
config.from_envar("DEBUG")
config["DEBUG"]  # True
