method exec, execW

method exec, execW

from, to, offsets = regex_object:exec (subj [, init])

Parameters:
  subj   :  string
  init   :  integer (default=1; can be negative)

Returns:
  from    : integer
  to      : integer
  offsets : table - array of captures' offsets (there can be false
                    in place of captures not participated in the match)

Example:
  If the whole match is at offsets 10,20 and substring matches are
  at offsets 12,14 and 16,19 then the method returns the following:
  10, 20, { 12,14,16,19 }.
