# String.next (from ruby core) --- next() --- Returns the successor to `self`. The successor is calculated by incrementing characters. The first character to be incremented is the rightmost alphanumeric: or, if no alphanumerics, the rightmost character: 'THX1138'.succ # => "THX1139" '<<koala>>'.succ # => "<<koalb>>" '***'.succ # => '**+' The successor to a digit is another digit, "carrying" to the next-left character for a "rollover" from 9 to 0, and prepending another digit if necessary: '00'.succ # => "01" '09'.succ # => "10" '99'.succ # => "100" The successor to a letter is another letter of the same case, carrying to the next-left character for a rollover, and prepending another same-case letter if necessary: 'aa'.succ # => "ab" 'az'.succ # => "ba" 'zz'.succ # => "aaa" 'AA'.succ # => "AB" 'AZ'.succ # => "BA" 'ZZ'.succ # => "AAA" The successor to a non-alphanumeric character is the next character in the underlying character set's collating sequence, carrying to the next-left character for a rollover, and prepending another character if necessary: s = 0.chr * 3 s # => "\x00\x00\x00" s.succ # => "\x00\x00\x01" s = 255.chr * 3 s # => "\xFF\xFF\xFF" s.succ # => "\x01\x00\x00\x00" Carrying can occur between and among mixtures of alphanumeric characters: s = 'zz99zz99' s.succ # => "aaa00aa00" s = '99zz99zz' s.succ # => "100aa00aa" The successor to an empty String is a new empty String: ''.succ # => "" String#next is an alias for String#succ.
