Installation

pip install configuraptor

Usage

Configuraptor can be used to load your config files into structured Python classes.

# examples/example_from_readme.toml
[config]
name = "Hello World!"

[config.reference]
number = 42
numbers = [41, 43]
string = "42"

Could be loaded into Python classes using the following code:

# examples/example_from_readme.py
from configuraptor import load_into, TypedConfig


######################
# with basic classes #
######################

class SomeRegularClass:
    number: int
    numbers: list[int]
    string: str


class Config:
    name: str
    reference: SomeRegularClass


if __name__ == '__main__':
    my_config = load_into(Config, "example_from_readme.toml")  # or .json, .yaml

    print(my_config.name)
    # Hello World!
    print(my_config.reference.numbers)
    # [41, 43]


########################
# alternative notation #
########################

class SomeOtherRegularClass:
    number: int
    numbers: list[int]
    string: str


class OtherConfig(TypedConfig):
    name: str
    reference: SomeRegularClass


if __name__ == '__main__':
    my_config = OtherConfig.load("example_from_readme.toml")  # or .json, .yaml

    print(my_config.name)
    # Hello World!
    print(my_config.reference.numbers)
    # [41, 43]

    # TypedConfig has an extra benefit of allowing .update:
    my_config.update(numbers=[68, 70])

More examples can be found in examples.

Supported Config File Types

• .toml: supports the most types (strings, numbers, booleans, datetime, lists/arrays, dicts/tables);
• .json: supports roughly the same types as toml (except datetime);
• .yaml: supports roughly the same types as toml, backwards compatible with JSON;
• .env: only supports strings. You can use convert_types=True to try to convert to your annotated types;
• .ini: only supports strings. You can use convert_types=True to try to convert to your annotated types;
