BaseConfig

BaseConfig(**kwargs)

Bases: BaseModule

Base configuration class that serves as parent for all configuration classes.

A config should inherit BaseConfig and specify the attributes and their types. Otherwise this will be an empty config.

from_str classmethod

from_str(content: str, **kwargs) -> BaseModule

This method is more forgiving than from_json as it can extract valid JSON objects embedded within larger text. It uses parse_json_from_text to extract all potential JSON strings from the input text, then tries to create an instance from each extracted JSON string until successful.

Parameters:

    By default, it opens the specified file and uses `yaml.safe_load` to parse its contents 
    into a Python object (typically a dictionary).

from_file classmethod

from_file(path: str, load_function: Callable = None, **kwargs) -> BaseModule

Construct the BaseModule from a file.

This method reads and parses a file into a data structure, then creates a module instance from that data. It first verifies that the file exists, then uses either the provided load_function or the default load_module method to read and parse the file content, and finally calls from_dict to create the instance.

Parameters:

Name	Type	Description	Default
path	str	The path of the file	required
load_function	Callable	The function used to load the data, takes a file path as input and returns a JSON object	None
**kwargs	Any	Additional keyword arguments, can include log to control logging output	{}

Returns:

Name	Type	Description
BaseModule	BaseModule	The created module instance

Raises:

Type	Description
ValueError	When the file does not exist
