Generalized all-in-one parameters module.
This package provides a single interface to environment variables, configuration files, and command line arguments. The dictionary-like interface makes interacting with these disparate resources much simpler. It also allows parameters' values to be set in any of the three sources and selects an appropriate value when a parameter's value is specified in multiple sources. This way the most expected value is always returned according to the following prcedence: command line arguments then configuration files then environment variables.
I am providing code in the repository to you under an open source license. Because this is my personal repository, the license you receive to my code is from me and not my employer (Facebook).
Usage of this package is outlined in the documentation.
Very simple example:
from crumbs import Parameters parameters = Parameters() parameters.add_parameter(options=["--foo"]) parameters.parse() parameters["foo"]
add_parameter is only a slight modification on
argparse.ArgumetParser.add_argument. The major difference is all
positional arguments to
argparse's version are handled by the
argument in ours.
