Method: Keybox::HighLineUtil#prompt

Defined in:
lib/keybox/highline_util.rb

#prompt(p, options) ⇒ Object

Prompt for input, returning what was typed. Options can be passed in.

If echo is false, then ‘*’ is printed out for each character typed in. If it is any other character then that is output instead.

If validate is set to true, then it will prompt twice and make sure that the two values match
