# frozen-string-literal: true module DidYouMean # The +DidYouMean::Formatter+ is the basic, default formatter for the # gem. The formatter responds to the +message_for+ method and it returns a # human readable string. class Formatter # 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::Formatter.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 self.message_for(corrections) corrections.empty? ? "" : "\nDid you mean? #{corrections.join("\n ")}" end def message_for(corrections) warn "The instance method #message_for has been deprecated. Please use the class method " \ "DidYouMean::Formatter.message_for(...) instead." self.class.message_for(corrections) end end PlainFormatter = Formatter deprecate_constant :PlainFormatter end
