I have a program with ~20 configs, which I would like to be accessed from the command-line via argparse, either by something like --config_1 'This is the first config' or --config-location <path_to_config_file>, where the path to the config file would be a .txt of form:
--config_1 'This is the first config'
--config_2 '2nd Config'
--config_3 3
...
Currently, my code looks something like:
parser = argparse.ArgumentParser()
parser.add_argument('--config_1')
args = vars(parser.parse_args())
This approach was inspired by youtube-dl's --config-location. If there's a better way to accomplish what I'm trying to do, suggestions are also appreciated and welcome. Thank you for reading!
argparse supports something similar out of the box.
parser = ArgumentParser(fromfile_prefix_chars='@')
parser.parse_args()
Now any argument starting with @ will be treated as a filename to be read, which each line being treated as a separate argument. This would require your file to look like
--config_1
This is the first config
--config_2
2nd Config
--config_3
3
...
instead.
What youtube-dl does is simply open the file, read its contents, and split it on whitespace similar to how the shell would.
