Example Code

import typer


app = typer.Typer(no_args_is_help=True)


@app.command(no_args_is_help=True)
def example(
    user: str = typer.Option("", envvar="EXAMPLE_USER", prompt="user", help="example user to print"),
    password: str = typer.Option("", envvar="EXAMPLE_PASSWORD", prompt="password", hide_input=True, help="example password to print")
    ):
    """Example command."""
    print(f"{user} | {password}")

Description

• I am creating a simple cli command that has optional parameters that take in a user name and password
• When running the above command, I notice that the prompt is adding [] to the prompt string:

user []:
password []:

• I have tried this without a custom prompt string, by setting prompt to true prompt=True but the issue occurs there too
• What I expect to occur is that [] would not be present in the prompt string output to CLI

Additional Context

The above example code is just that, an example. The actual command also has positional arguments and is itself a nested subcommand. Don't know if that impacts this.

Hey

I've did not verify that one but Ive you really dont want these [] you could add a callback like this to format the value passed from the input.
https://typer.tiangolo.com/tutorial/commands/context/

import typer


app = typer.Typer(no_args_is_help=True)

def some_callback(ctx, parameter, value):
    print(value)


@app.command(no_args_is_help=True)
def example(
    user: str = typer.Option("", envvar="EXAMPLE_USER", prompt="user", help="example user to print", callback=some_callback) ):
    """Example command."""
    print(f"{user} | {password}")

I think that is showing the default value, an empty string.

You could also try to prompt the user manually.

This comes directly from Click, so there's not really much that Typer can do about it. 😅
