Overview

Demande de confirmation utilisateur pour CLI

Présentation

ask_lib est un module pour le langage Python proposant une seule fonction; ask(). Le but principal de cette fonction est de proposer un wrapper de la fonction input() pour demander la confirmation de l'utilisateur avant de réaliser une action. ask_lib est donc particulièrement utile pour la création de CLI.

Exemple

import os

from ask_lib import AskResult, ask

reponse = ask("Êtes-vous sûr de vouloir supprimer ce fichier ?", AskResult.YES)
if reponse:
    try:
        os.remove("fichier.txt") # Supprime le fichier | A titre d'exemple
    except Exception:
        print("Quelque chose s'est mal passé...")
    else:
        print("Le fichier vient d'être supprimé.")
else:
    print("Le fichier n'a pas été supprimé.")

Point de vu de l'utilisateur ;

Êtes-vous sûr de vouloir supprimer ce fichier ? [Y/n] n
Le fichier n'a pas été supprimé.

Êtes-vous sûr de vouloir supprimer ce fichier ? [Y/n] y
Le fichier vient d'être supprimé.

    No support for automatic agreement.

    Hi !

    I see no provided interface that permits to automatically accept a request. It would be interesting to implement such feature. It could be used for commands launched automatically, for instance, in a container, to install some libraries before the deployment step.

    The implementation of this feature could bring you to create a "verbose" flag. This flag could allow to not print the request on the screen. It could be great to implement this with the automatic agreement because it is not necessary to print the request if it is automatically accepted.
