`anton` is a Python library for auto instantiating yaml definitions to user defined dataclasses.

Avoid boilerplate and get runtime type checking before the objects are created.

## Usage

Given a `yaml` file definition in a file `index.yaml` as follows:

```yaml
# index.yaml
integer: 23
string: "Hello world"
point:
x: 0
y: 0
line_segment:
first_point:
x: 10
y: 10
second_point:
x: 10
y: 10
```

`yaml_conf` lets you avoid writing the biolerplate code for loading the `yaml` file and parsing the python dictionary to instantiate the Dataclass object as follows:

```py
>>> from dataclasses import dataclass
>>> from anton import yaml_conf
>>>
>>> @dataclass
... class Point:
... x: int
... y: int
...
>>> @dataclass
... class LineSegment:
... first_point: Point
... second_point: Point
...
>>> @yaml_conf()
... class ExampleClass:
... integer: int
... string: str
... point: Point
... line_segment: LineSegment
...
>>> example_obj = ExampleClass(conf_path="index.yaml")
>>> example_obj
ExampleClass(integer=23, string='Hello world', point=Point(x=0, y=0), line_segment=LineSegment(first_point=Point(x=10, y=10), second_point=Point(x=10, y=10)))
```

## Roadmap

Currently the project only supports Python3.8

Runtime type checking is supported for the following types:
- int
- float
- str
- bool
- typing.List
- typing.Dict
- typing.Union
- Any user defined dataclass

The ultimate aim is to support all python versions Python3.8+ and all possible type combinations.
