heracless 0.2.2

Yaml to Dataclass parser for Config files

heracless

Config Manager using yaml.

Description

heracless aims to make working with config files in python easy. It parses a config file into a dataclass and creates types as a python file with can be used for type hints. Generated types also make autocompletion a dreamy!

Usage

first create a config file in yaml format and put in your desired fields. to access the config information do like in following sample code.

from heracless import heracless
from config.types import Config

@heracless()
def main(cfg:Config) -> Any: 
"""
simply add a cfg parameter to any function at the first place
and access config attributes like you do any with any other object
"""
    some_sample_config_value = config.sample.some_value

its as simple as that!

or simply use the load_config function to load the config file into a dataclass

from heracless import load_config
from config.types import Config

@heracless()
def main(*args,**kwargs) -> Any: 
    config = load_config()
    print(config.sample.some_value)

arguments:

• cfg_path:Path yaml config file path -> Default ./config/config.yaml
• dump_dir:Path Path where types are going to be written to -> Default ./config/types.py
• dump_func:Callable control's the dumping behavior -> options: heracless.dump_in_file|heracless.dump_in_console| heracless.dump_dummy -> Default dump_in_file
• frozen:bool whether dataclass config objects are mutable or not -> Default True
• make_dir:bool make given paths or not if not existing -> Default True

Cli-Tool

heracless also comes with a cli tool to generate the types file from a config file simply run the following command in your terminal

heracless path/to/config.yaml -p path/to/types.py # generates types file
heracless path/to/config.yaml -d # dumps types to console
heracless path/to/config.yaml -h # for help

Sure, here's a markdown document that describes the functions in helper.py and provides example usage:

Helper Functions in Heracless

This document describes the helper functions in the helper.py module of the Heracless project.

mutate_config

This function takes a Config object, a name, and a value, and returns a new Config object with the value at the name updated.

from heracless.utils.helper import mutate_config
from heracless.utils.c_types import Config

config = Config(...)  # Initialize a Config object
new_config = mutate_config(config, "name", "new_value")

as_dict

This function converts a Config object to a dictionary.

from heracless.utils.helper import as_dict
from heracless.utils.c_types import Config

config = Config(...)  # Initialize a Config object
config_dict = as_dict(config)

from_dict

This function creates a Config object from a dictionary. You can specify whether the Config object should be frozen.

from heracless.utils.helper import from_dict

config_dict = {...}  # A dictionary representing the configuration
config = from_dict(config_dict, frozen=True)

---

Remember to replace Config(...) and {...} with actual Config objects and dictionaries.
