Method: HighLine#agree

Defined in:
lib/highline.rb

#agree(yes_or_no_question, character = nil) ⇒ Object

A shortcut to HighLine.ask() a question that only accepts “yes” or “no” answers (“y” and “n” are allowed) and returns true or false (true for “yes”). If provided a true value, character will cause HighLine to fetch a single character response. A block can be provided to further configure the question as in HighLine.ask()

Raises EOFError if input is exhausted.

Parameters:

  • yes_or_no_question (String) —

    a question that accepts yes and no as answers

  • character (Boolean, :getc) (defaults to: nil) —

    character mode to be passed to Question#character
