✨ feat: Interactive CLI input

[raxhvl]

🗒️ Description

This PR adds a set of simple, HTML-like input functions to the cli.input package, which internally use the questionary library to handle various types of interactive CLI inputs. The goal is to provide a simplified API for capturing user input, WITHOUT exposing the details of questionary.

This makes it easy to swap out questionary for another library in the future, without changing the interface. Use away!

Changes

• New Input Functions:
  • input_text(question: str): Ask a text input question.
  • input_password(question: str): Ask a password input question (hidden text).
  • input_select(question: str, choices: list): Ask a single-choice selection question.
  • input_checkbox(question: str, choices: list): Ask a multi-choice question.
  • input_confirm(question: str): Ask a yes/no confirmation question.

Usage Example

from cli.input import input_checkbox, input_confirm, input_password, input_select, input_text


def main():
    name = input_text("What is your name?")
    password = input_password("Enter your password:")
    color = input_select("Choose your favorite color", choices=["Red", "Green", "Blue"])
    selected_colors = input_checkbox(
        "What colors do you like?", choices=["Red", "Green", "Blue", "Yellow"]
    )
    continue_choice = input_confirm("Do you want to continue?")

    print(f"Hello, {name}!")
    print(f"Password received length {len(password)}.")
    print(f"You selected {color}.")
    print(f"Selected colors: {', '.join(selected_colors)}")
    print("Continuing..." if continue_choice else "Stopping.")


if __name__ == "__main__":
    main()
