ASKpy - Collect Input from your Users

ASKpy is a module which makes collecting Raw Input for your Python program more robust. It supports creating prompts, conditional questions, validation, and transforming responses.

Installation

Installing ASKpy is as simple as:

dansackett

#!/bin/sh

command="${*}"
printf "Initialized REPL for [%s]\n" "$command"
printf "%s> " "$command"
read -r input
while [ "$input" != "" ];
do
    eval "$command $input"
    printf "\n%s> " "$command"
