Custom Loaders
==============

You may wish to use a config file in a format that ``ClassyConfig`` doesn't support.

Here is an example of creating a simple config loader for ``.txt`` files.

.. code-block:: python

    from pathlib import Path

    from classy_config import ConfigValue, register_config, register_loader


    def txt_loader(filepath: Path) -> dict:
        out = {}

        with filepath.open() as f:
            for line in f.readlines():
                key, value = line.split(">")
                out[key] = value

        return out


    register_loader(".txt", txt_loader)
    register_config("config.txt")

    print(f"data: {ConfigValue('data', int)}")
    print(f"name: {ConfigValue('name', str)}")
