Inputs

Really stupid primitive Gem that will handle some common console operations.

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.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'

Installation

Option 1:

gem install inputs

Option 2 (If you use bundler) :

# Gemfile
gem 'inputs'

And then execute:

$ bundle

Example

# foo.rb
require 'inputs'

class Foo
  def call
    name = Inputs.name("what is your name")

    if Inputs.yn("Ok #{name}, do you want to learn music instrument?")
      instrument = Inputs.pick(instrument_options)

      case instrument
      when drums
        puts 'Metal dude ! \,,/'
      when guitar
        puts "Rock on dude !"
      when harp
        puts "W.T.F dude ?"
      end
    else
      puts "Then go home #{name} !"
    end
