Feature #3388

Updated by nahi (Hiroshi Nakamura) over 12 years ago

=begin 
  
  ruby-1.9.2-head > "aBcdeFghIj".start_with?(/abc/i) 
  => false  
 
  In my implementation of start_with? it is easy enough to utilize #index, which works fine: 
 
    def start_with?(pattern) 
      index(pattern) == 0 
    end 
 
  But #end_with? is more difficult, and I had to use regular expressions. 
 
      def end_with?(suffix) 
        suffix = Regexp.escape(suffix) if String===suffix 
        /#{suffix}$/.match(self) ? true : false 
      end 
 
  However, we might get rid of the '? true : false' and return the MatchData, since that could be useful information.
