Description

I have a poetry package with a Typer object as entrypoint. A subcommand has the following --help page:

poetry run typer_argdash -vv command first --help
                                                                                                   
 Usage: typer_argdash command first [OPTIONS] A B                                                  
                                                                                                   
╭─ Arguments ─────────────────────────────────────────────────────────────────────────────────────╮

│ *    b      TEXT  [default: None] [required]                                                    │

│ --help                Show this message and exit.                                               │

I want to be able to pass -something as a. For instance:

poetry run typer_argdash -vv command first --no-c -1 '2'

But that raises this error:

poetry run typer_argdash -vv command first -1 2 --no-c
Usage: typer_argdash command first [OPTIONS] A B
Try 'typer_argdash command first --help' for help.
╭─ Error ───────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╮
│ No such option: -1                                                                                                                                                                                            │
╰────────────────

As per #134, this should do the trick:

poetry run typer_argdash -vv command first --no-c -- -1 2
Usage: typer_argdash command first [OPTIONS] A B
Try 'typer_argdash command first --help' for help.
╭─ Error ───────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╮
│ No such option: -1                                                                                                                                                                                            │
╰───────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────╯

But errors as well.

Is there any way to do this?

The following code work well in current version (0.17.4):

import typer

cli = typer.Typer()

@cli.command()
def first(a: str, b: str, c: bool = False):
    typer.secho(f"{a=} {b=} {c=}")

@cli.command()
def second(a: str, b: str, c: bool = False):
    typer.secho(f"{a=} {b=} {c=}")

if __name__ == "__main__":
    cli()

Try:

$ python main.py first --no-c -- -1 2
a='-1' b='2' c=False
