There's no built-in way to rename an argument. Plus metavar param probably should change only the type representation of an argument.

Example Code

from typer import Typer

app = Typer()


@app.command()
def complete_task(id_: int):  # I want it to be shown as id & ID in the help
    pass

Description

I need a way to rename the argument from id_ to id in the help message. Additionally, it should be displayed in uppercase in the usage section. I've found a recommendation to use metavar for this, but it changes the type representation of the argument and how it's displayed in the usage section, which is not what I need.

I'd like to have a name parameter for this in the Argument.

I'm also looking to understand how to do this. I don't like that my arguments use underscores and my options use hyphens.
