configfile

This is a simple package to manage configurations.

Usage

First, define a child class of ConfigBase than implements set_parameters(self). This methods sets all parameters to be handled in the configuration just with the typical self.param_name=value

from configfile.configbase import ConfigBase

class MyConfig(ConfigBase):
    def set_parameters(self):
        self.floatParam=1. #The type will be automatically inferred if no type hint provided
        self.intParam=1
        self.intParamNoneDefault:Optional[int]=None #Type hints required if the argument is set to None
        self.listParam:List[float]=[1.,12.] #Type hint is not required here, but still useful
        

Then the configuration parameters can be accessed using the dot or bracket access

It can also allow for dynamic change of the parameters as it were a dictionary and from environmental variables named NAME___PARAMETERNAME, where NAME is provided by the user at building time. Dicts are flattened by adding "__" between different levels

It also allow to generate an automatic argument parser:

from configfile.configbase import ConfigBase
from argparse import ArgumentParser

class MyConfig(ConfigBase):
    def set_parameters(self):
        self.floatParam=1. #The type will be automatically inferred if no type hint provided
        self.one_list:List[float]=[1.,12.]
        self.null_list:Optional[List[float]]=None
        
conf = MyConfig(name="NAME_TO_BE_USED_IN_ENV_VARS")
parser = ArgumentParser()
conf.add_args_to_argparse(parser)
parser.print_help()
pars = parser.parse_args(["--one_list", "3", "82"])
assert abs(sum(pars.one_list) - sum([3, 82])) < 0.001
