Ask with Prompt
When you need to ask the user for info interactively you should normally use CLI Options with Prompt, because they allow using the CLI program in a non-interactive way (for example, a Bash script could use it).
But if you absolutely need to ask for interactive information without using a CLI option, you can use typer.prompt()
:
import typer_cloup as typer
def main():
person_name = typer.prompt("What's your name?")
typer.echo(f"Hello {person_name}")
if __name__ == "__main__":
typer.run(main)
Check it:
$ python main.py
# What's your name?:$ Camila
Hello Camila
Confirm¶
There's also an alternative to ask for confirmation. Again, if possible, you should use a CLI Option with a confirmation prompt:
import typer_cloup as typer
def main():
delete = typer.confirm("Are you sure you want to delete it?")
if not delete:
typer.echo("Not deleting")
raise typer.Abort()
typer.echo("Deleting it!")
if __name__ == "__main__":
typer.run(main)
Check it:
$ python main.py
# Are you sure you want to delete it? [y/N]:$ y
Deleting it!
// This time cancel it
$ python main.py
# Are you sure you want to delete it? [y/N]:$ n
Not deleting
Aborted!
Confirm or abort¶
As it's very common to abort if the user doesn't confirm, there's an integrated parameter abort
that does it automatically:
import typer_cloup as typer
def main():
delete = typer.confirm("Are you sure you want to delete it?", abort=True)
typer.echo("Deleting it!")
if __name__ == "__main__":
typer.run(main)
$ python main.py
# Are you sure you want to delete it? [y/N]:$ y
Deleting it!
// This time cancel it
$ python main.py
# Are you sure you want to delete it? [y/N]:$ n
Aborted!
