Example Code

# I want to get something like this

def install_completion_option():
    answer = input("Are you sure you want to use the --install-completion command?"
               " This will make changes to the .bashrc file")
    if answer == "yes":
        # --install-completion is performed here

Description

I want to override the functionality of the --install-completion command. I want to warn the user that the .bashrc file will be modified after this operation. Is it possible ?

I am trying to run the install() function from the typer.completion module as follows:

import click
import typer
from typer.completion import install
from typer.core import TyperGroup as TyperGroupBase

app = typer.Typer(
    name="capsule", help="capsule CLI", no_args_is_help=True, cls=TyperGroup, add_completion=False
)

@app.callback(
    invoke_without_command=True,
    help="""capsule: a packaging system for notebook-based projects.""",
)
def main(
    install_completion: Optional[bool] = typer.Option(
        False, "--install-completion", help="Install completion"
    ),
) -> None:
    if install_completion:
        answer = input(
            "Are you sure you want to use the --install-completion command?"
            " This will make changes to the .bashrc file")
        if answer == "yes":
            install()
    typer.Exit()

if __name__ == "__main__":
    app()

but I didn't get what I want because when I press TAB it always shows "plain" before the option is completed like this

myapp n[TAB] -> myapp plain, new

instead:

myapp n[TAB] -> myapp new
