Library for prompting users for input

Add this line to your application's Gemfile:

gem 'list_picker'

And then execute:

$ bundle

Or install it yourself as:

$ gem install list_picker

require 'list_picker'

array = %w{ Option1 Option2 Option3 }
chosen_option = ListPicker::Picker.new(array).ask("Please select from list of available options")

You can use objects and define method that will be used to be displayed in the list. In order to do that, you can pass in options to the constructor:

require 'list_picker'

array = (1..10).map do |i|
	Time.new(Time.now.year + i)
end

chosen_option = ListPicker::Picker.new(array, label_method: :year).ask("Please select a year from the list")

ListPicker reads arguments passed into the script so that you can predefine your ansers. For instance:

Take for example file test.rb with contents:

require 'list_picker'

array = (1..10).map do |i|
	Time.new(Time.now.year + i)
end

chosen_option = ListPicker::Picker.new(array, label_method: :year).ask("Please select a year from the list")

You can then invoke it by calling:

ruby test.rb 4

This will have preselected 4th option from the list
