Creating a config class

can have a toml/ini in ~/.config/module/config.toml to read the values in

os.path.expanduser('~') - expands the tilde to the home directory

suggestion: save configs in ~/.config/module

os.environ.get('VIRTUAL_ENVs', expand) - will get the env variable and fall back to the default afterwards if its not specified. 

Method to read from an os env, and then fall back on another way if it doesnt exist:

    def get(self, key, default=None, cast=None):
        """ Returns the specified configuration value or <default> if not found.
            Parameters:
                key (str): Configuration variable to load in the format '<section>.<variable>'.
                default: Default value to use if key not found.
                cast (func): Cast the value to the specified type before returning.
        """
        try:
            # First: check environment variable is set
            envkey = 'PLEXAPI_%s' % key.upper().replace('.', '_')
            value = os.environ.get(envkey)
            if value is None:
                # Second: check the config file has attr
                section, name = key.lower().split('.')
                value = self.data.get(section, {}).get(name, default)
            return cast(value) if cast else value
        except:  # noqa: E722
            return default


- To open a config .toml:
    toml.load(file) where file has a default value of the ~/.config/module/module.toml
    If the toml file doesn't exist, nor has a path been passed in, pass and fall back to other methods (os envs, cli)

- Have a get method, that checks the config file for the result, and then tries the env variable.



-- set the path to the toml in the __init__.py, check for a config file override path and fall back to default if not

# Load User Defined Config
DEFAULT_CONFIG_PATH = os.path.expanduser('~/.config/plexapi/config.ini')
CONFIG_PATH = os.environ.get('PLEXAPI_CONFIG_PATH', DEFAULT_CONFIG_PATH)
CONFIG = PlexConfig(CONFIG_PATH)

- each module/submodule should have the header set to the section it corresponds to in the .toml file.

e.g a reddit module that needs access to the reddit options should have
__section__ = 'reddit'

this would correspond to
[reddit]
PLEXPOSTERS_REDDIT_ env var


-- the __init__ of the module should instantiate this config class:

# Load User Defined Config
DEFAULT_CONFIG_PATH = os.path.expanduser('~/.config/plexapi/config.ini')
CONFIG_PATH = os.environ.get('PLEXAPI_CONFIG_PATH', DEFAULT_CONFIG_PATH)
CONFIG = PlexConfig(CONFIG_PATH)

other modules can import this instantiated class

the __init__ of the module should also set all the default values as capital vars e.g. 

PLEX_USERNAME = plexPosterConfig.get(f'{__section__}.username')
