Collection of common interactive command line user interfaces, based on Inquirer.js.

Goal and Philosophy

Born as a Inquirer.js clone, it shares part of the goals and philosophy.

So, Inquirer should ease the process of asking end user questions, parsing, validating answers, managing hierarchical prompts and providing error feedback.

Objects

The main object is Question, but it should not be instantiated. You must use any of the subclasses, listed below. All of them have the next attributes that can be set in the initialization:

Attribute	Type	Explanation
name	String	The key in the hash of answers.
message	String	To be shown in the prompt to the user
default	Any|Function	Default value. Functions will receive the hash with previous values.
choices	List|Function	List of available options. Functions will receive the hash with previous values.
validate	Bool|Function	If the value set is valid. Functions will receive the hash with previous values and the value set in this question, and should return a boolean.
ignore	Bool|Function	If the quiestion should be shown. Functions will receive the hash with previous values and should return a boolean.
