Highline::Wizard

Highline Wizard is a library to help you getting options. That options should be passed as a 2 dimension array.

Installation

Add this line to your application’s Gemfile:

gem 'highline-wizard'

And then execute:

$ bundle

Or install it yourself as:

$ gem install highline-wizard

Usage

In your ruby script

“by require ‘highline/wizard’

OPTIONS = [%W( icecream chocolate extra-topping 4.5 ) %W( icecream chocolate no-topping 3.5 ) %W( cake chocolate no-topping 4.5 ) %W( cake vanilla no-topping 4.5 )]

selected = wizzard(OPTIONS) do titles « %w(desert flavor extra price) end

puts selected.inspect

“

This will generate to the user the following conversation:

“ell 1. icecream 2. cake Choose desert? 2

  1. chocolate
  2. vanilla Choose flavor? 1

{ “desert” => “cake”, “flavor” => “chocolate”, “extra” => “no-toppinng”, “price” => “4.5” }

“

Other option:

“ell 1. icecream 2. cake Choose desert? 1

  1. extra-topping
  2. no-topping Choose extra? 2

{ “desert” => “icecream”, “flavor” => “chocolate”, “extra” => “no-topping”, “price” => “4.5” }

“

As you can see, options that are not possible are not asked.
