class Athena::Console::Question::Choice(T)
inherits Athena::Console::Question::AbstractChoice #

A question whose answer MUCH be within a set of predefined answers. If the user enters an invalid answer, an error is displayed and they are prompted again.

question = ACON::Question::Choice.new "What is your favorite color?", {"red", "blue", "green"}
color = helper.ask input, output, question

This would display something like the following:

What is your favorite color?
 [0] red
 [1] blue
 [2] green
>

The user would be able to enter the name of the color, or the index associated with it. E.g. blue or 2 for green. If a Hash is used as the choices, the key of each choice is used instead of its index.

Similar to ACON::Question, the third argument can be set to set the default choice. This value can also either be the actual value, or the index/key of the related choice.

question = ACON::Question::Choice.new "What is your favorite color?", {"c1" => "red", "c2" => "blue", "c3" => "green"}, "c2"
color = helper.ask input, output, question

Which would display something like :

What is your favorite color?
 [c1] red
 [c2] blue
 [c3] green
