Arguments: add_config_file_help: Whether to add a description of config file syntax to the help message. add_env_var_help: Whether to add something to the help message for args that can be set through environment variables. auto_env_var_prefix: If set to a string instead of None, all config- file-settable options will become also settable via environment variables whose names are this prefix followed by the config file key, all in upper case. (eg. setting this to ``foo_`` will allow an arg like ``--my-arg`` to also be set via the FOO_MY_ARG environment variable) default_config_files: When specified, this list of config files will be parsed in order, with the values from each config file taking precedence over previous ones. This allows an application to look for config files in multiple standard locations such as the install directory, home directory, and current directory. Also, shell \* syntax can be used to specify all conf files in a directory. For example:: ["/etc/conf/app_config.ini", "/etc/conf/conf-enabled/*.ini", "~/.my_app_config.ini", "./app_config.txt"] ignore_unknown_config_file_keys: If true, settings that are found in a config file but don't correspond to any defined configargparse args will be ignored. If false, they will be processed and appended to the commandline like other args, and can be retrieved using parse_known_args() instead of parse_args() config_file_open_func: function used to open a config file for reading or writing. Needs to return a file-like object. config_file_parser_class: configargparse.ConfigFileParser subclass which determines the config file format. configargparse comes with DefaultConfigFileParser and YAMLConfigFileParser. args_for_setting_config_path: A list of one or more command line args to be used for specifying the config file path (eg. ["-c", "--config-file"]). Default: [] config_arg_is_required: When args_for_setting_config_path is set, set this to True to always require users to provide a config path. config_arg_help_message: the help message to use for the args listed in args_for_setting_config_path. args_for_writing_out_config_file: A list of one or more command line args to use for specifying a config file output path. If provided, these args cause configargparse to write out a config file with settings based on the other provided commandline args, environment variants and defaults, and then to exit. (eg. ["-w", "--write-out-config-file"]).

Default: False is_write_out_config_file_arg: If True, this arg will be treated as a config file path, and, when it is specified, will cause configargparse to write all current commandline args to this file as config options and then exit.
