load config from command arguments

[ZhiyuanChen]

config.parse has a parameter named default_config. This allow you to apply your CLI arguments on a config file.

from chanfig import Config
from rich import print


if __name__ == '__main__':
    config = config.parse(default_config="config")
    print(config)

python xxx.py --config default.yaml

Thank you. It fixed it.

sorry for the late response, I have just tested the snippet, however, when run with --help, it won't show keys in the configuration file, even run with --config.

❯ python run.py --config configs/exps/test.yaml --help
usage: run.py [-h] [--config CONFIG]

options:
  -h, --help       show this help message and exit
  --config CONFIG

  --config CONFIG

Im not sure if it’s possible to achieve this.

Merging a config file happens after parsed the command line arguments.

--help is handled by argparse when parsing the command line arguments.

Yes, I know it is a little weird to load from config and then add to the argparse, but it could be better if we can support this. This may change a lot of logic when loading and parsing the config.

Yes, I'll need some time for this, hopefully by the end of August.
