bjorn

The Bjorn module loads a configuration file for your python script.

Installation
To install bjorn, run this command in your terminal:
$ pip install bjorn

The basics
A settings file is just a Python module with module-level variables.
Settings example:
import os

LOGGING_CONFIG = {
"version": 1,
"disable_existing_loggers": False,
"formatters": {
"standard": {"format": "%(asctime)s [%(levelname)s] %(name)s: %(message)s"},
},
"handlers": {
"default": {
"level": "INFO",
"formatter": "standard",
"class": "logging.StreamHandler",
},
"file_handler": {
"level": "INFO",
"filename": "/tmp/mylogfile.log",
"class": "logging.FileHandler",
"formatter": "standard",
},
},
"loggers": {
"job": {
"handlers": ["default"],
"level": os.environ.get("LOGGER_LEVEL", "INFO"),
"propagate": True,
},
},
}

VALUE_TO_TEST = "A"
Because a settings file is a Python module, the following apply:

It doesn’t allow for Python syntax errors.
It can assign settings dynamically using normal Python syntax. For example:

MY_SETTING = [str(i) for i in range(30)]

Designating the settings
JOB_SETTINGS
When you use Bjorn, you have to tell it which settings you’re using. Do this by using an environment variable, JOB_SETTINGS.
The value of JOB_SETTINGS should be in Python path syntax, e.g. mysite.settings. Note that the settings module should be on the Python import search path.

Usage
Create a settings.py file in the root of the project. Then you can call it from your script using the following way.
from bjorn.config import settings

if __name__ == '__main__':
print(settings.VALUE_TO_TEST)
