dataclasses-hjson 0.0.3

A simple mixin that adds .to_hjson and .from_hjson to the dataclasses-json mixin

dataclasses-hjson

This package provides a simple way to serialize and deserialize dataclasses to and from Hjson.

This uses dataclasses-json to serialize and deserialize dataclasses, and hjson to parse and generate Hjson.

Opposed to dataclasses-json, this package does only provide a mixin class to add the functionality to a dataclass, instead of a decorator. You can change the configuration of dataclasses-json by either using the using_config decorator or by manually setting the dataclasses_json_config attribute on the dataclass, using the hjson_config function.

If you have any problems, ideas or suggestions, feel free to open an issue or a pull request!

Installation

pip install dataclasses-hjson

Usage

Example adding config using the using_config decorator:

from dataclasses import dataclass
from dataclasses_json import Undefined, LetterCase
from dataclasses_hjson import DataClassHjsonMixin, using_config


@using_config(
    undefined=Undefined.EXCLUDE, letter_case=LetterCase.CAMEL
)  # (These are the default values)
@dataclass
class Person(DataClassHjsonMixin):
    first_name: str
    age: int

Alternatively, you can use the hjson_config function:

from dataclasses import dataclass
from dataclasses_json import Undefined, LetterCase
from dataclasses_hjson import DataClassHjsonMixin, hjson_config


@dataclass
class Person(DataClassHjsonMixin):
    dataclasses_json_config = hjson_config(undefined=Undefined.EXCLUDE, letter_case=LetterCase.CAMEL) # (These are the default values)

    first_name: str
    age: int

Adding the config is optional however!

Now you can serialize and deserialize the dataclass to and from Hjson:

person = Person(first_name="Guido", age=42)
person_json = person.to_hjson()
print(person_json)
# {
#   firstName: Guido
#   age: 42
# }
person_copy = Person.from_hjson(person_json)
print(person_copy)
# Person(name='Guido', age=42)
