Load/Save

This example builds on Config/Data. It loads the config if it exists otherwise it returns the default config.

Code

import json

from .default import get_config_file
from .model import Config

def _get_resolved_filename(filename):
    filename = Path(filename) if filename else get_config_file()
    return filename.expanduser()

def load(filename=None):
    filename = _get_resolved_filename(filename)
    if not filename.exists():
        return Config()
    with open(filename, "r") as f:
        data = json.load(f)
    return Config(**data)

def save(cfg, filename=None):
    filename = _get_resolved_filename(filename)
    with open(filename, "w") as f:
        json.dump(cfg.to_dict(), f)
    return True
