Inputs
Really stupid primitive Gem that will handle some common console operations.
Don't want to install gem ? There is a copy-paste version for your script Inputs copy-paste version
The gem aims to be really simple. If you looking for something more complex I recommend to use TTY,tty-prompt Reddit discussion
require 'inputs'
Inputs.yn('Are you stupid?')
# Are you stupid? [y/n]
# => true / false
Inputs.name('What is your name')
# What is your name
# => String
Inputs.name!('Do you want to skip this question?')
# What is your name
# => String or Nil if no input
Inputs.password('What is the password: ')
# What is the password:
# => String
Inputs.names('Names of your parents')
# Names of your parents
# => Array
Inputs.pick(['cat', 'dog'])
# Please choose
# Press 1 for "cat"
# Press 2 for "dog"
## after pressing 1
# => 'cat'
## after pressing 2
# => 'dog'

gem install inputs
