The formatter responds to the +message_for+ method and it returns a # human readable string. class PlainFormatter # Returns a human readable string that contains +corrections+. This # formatter is designed to be less verbose to not take too much screen # space while being helpful enough to the user. # # @example # # formatter = DidYouMean::PlainFormatter.new # # # displays suggestions in two lines with the leading empty line # puts formatter.message_for(["methods", "method"]) # # Did you mean? methods # method # # => nil # # # displays an empty line # puts formatter.message_for([]) # # # => nil # def message_for(corrections) corrections.empty? ? "" : "\nDid you mean? #{corrections.join("\n ")}" end end end
