A module for retrieving program settings from various sources in a consistant method.
This is a fork of setoptconf <https://github.com/jayclassless/setoptconf>
_ .
It is a temporary solution to fix prospector <https://github.com/PyCQA/prospector>
_
being unable to install due to setoptconf not working with setuptools >= 58 -
see the issue here <https://github.com/PyCQA/prospector/issues/438>
_.
This package is only meant as a temporary solution to fix CI builds using prosector until setoptconf can be removed from there. Therefore do not expect this fork to be maintained and it will be purged once prospector is updated.
setoptconf
is a Python library that can be used to retrieve program settings
from a variety of common sources:
The goal of this project is to define your desired settings in a simple and consistent way, and then point setoptconf at as many of the sources as you'd like to use, and let it comb them all, looking for your settings.
This README is admittedly very light on details. Full documentation will come in time. For now, here's an example of its use:
Import the library::
import setoptconf as soc
Instantiate the manager::
manager = soc.ConfigurationManager('myprogram')
Define the settings we'd like to collect::
manager.add(soc.StringSetting('foo'))
manager.add(soc.IntegerSetting('bar', required=True))
manager.add(soc.BooleanSetting('baz', default=True))
Retreive the settings from our desired sources, combining the settings and overriding with the priority implied by the order of the sources we pass::
config = manager.retrieve(
# This source pulls from the command line using argparse.
soc.CommandLineSource,
# This source pulls from environment variables that are prefixed
# with MYPROGRAM_*
soc.EnvironmentVariableSource,
# This source pulls from the named INI files. It stops at the first
# file it finds.
soc.ConfigFileSource(('.myprogramrc', '/etc/myprogram.conf')),
)
We now have a Configuration object named config
that has three attributes;
foo
, bar
, and baz
.
