Default value for `--config` in cli.py

[LKirst]

First of all, thank you for the cookiecutter template! I have one question about cli.py: Should the default for args.config not be a list?

If I'm not mistaken, parser.add_argument("-c", "--config", action="append") creates a list, but the default is a string, not a list with a single string value:

cookiecutter-python-app/{{cookiecutter.project_slug}}/src/{{cookiecutter.app_name}}/cli.py

Line 73 in 02c1c78

args.config = "etc/config.toml"

Would it not be easier to use a list as default args.config = ["etc/config.toml"], because then, I could always assume args.config is a list?

Good catch, yes, this should be args.config = ["etc/config.toml"] if you want to allow multiple config files. In practice I usually only have one config file, so I never noticed this mistake.

If you change this, be aware that there are other places that only expect a single value for args.config, e.g.

cookiecutter-python-app/{{cookiecutter.project_slug}}/src/{{cookiecutter.app_name}}/cli.py

Line 26 in 02c1c78

config.load(args.config, params=environ)
