Can't pass "help" parameter to click argument

[johnnymetz]

The following script works with the base click library but raises an exception with the django-click library.

import djclick as click

@click.command()
@click.argument("name", help="Some name")
def command(name):
    click.echo(f"Hi {name}!")

Exception:

I think you and I have both made this mistake @johnnymetz . Arguments don't have help text.

Someone else had the exact same problem here... pallets/click#466 ... so were also not the only two people 😄

Documenting Arguments

click.argument() does not take a help parameter. This is to follow the general convention of Unix tools of using arguments for only the most necessary things, and to document them in the command help text by referring to them by name.

Not sure if you want to close this as "user error" or wait for a reply, but id say its probably safe to say this isn't a bug in your library @GaretJax
