skip_until(p1) public

Advances the scan pointer until pattern is matched and consumed. Returns the number of bytes advanced, or nil if no match was found.

Look ahead to match pattern, and advance the scan pointer to the end of the match. Return the number of characters advanced, or nil if the match was unsuccessful.

It’s similar to #scan_until, but without returning the intervening string.

  s = StringScanner.new("Fri Dec 12 1975 14:39")
  s.skip_until /12/           # -> 10
  s                           #
