This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# StringScanner.scan (from ruby core) --- scan(pattern) => String --- Tries to match with `pattern` at the current position. If there's a match, the scanner advances the "scan pointer" and returns the matched string. Otherwise, the scanner returns `nil`. s = StringScanner.new('test string') p s.scan(/\w+/) # -> "test" p s.scan(/\w+/) # -> nil p s.scan(/\s+/) # -> " " p s.scan("str") # -> "str" p s.scan(/\w+/) # -> "ing" p s.scan(/./) # -> nil
