Positional config file arguments do not work when config file arg is not first #265
Description
Perhaps an odd situation, but if I use positional arguments AND my config file is not the first argument, the file is not opened. For example:
main.py
import configargparse
p = configargparse.get_argument_parser()
p.add_argument("first_argument")
p.add_argument("config", is_config_file=True)
p.add_argument("--option")
arguments = p.parse_known_args() # or parse_args()
print(arguments)
config.ini
option = yes
And execute it with
python main.py first config.ini:
usage: mwe-fails.py [-h] [--option OPTION] first_argument config
mwe-fails.py: error: Unable to open config file: first. Error: No such file or directory
However, if I switch the order of arguments and modify the command appropriately, I get the expected behavior
