    pygments.scanner
    ~~~~~~~~~~~~~~~~

    This library implements a regex based scanner. Some languages
    like Pascal are easy to parse but have some keywords that
    depend on the context. Because of this it's impossible to lex
    that just by using a regular expression lexer like the
    `RegexLexer`.

    Have a look at the `DelphiLexer` to get an idea of how to use
    this scanner.

        Scan the text for the given pattern and update pos/match
        and related fields. The return value is a boolean that
        indicates if the pattern matched. The matched value is
        stored on the instance as ``match``, the last value is
        stored as ``last``. ``start_pos`` is the position of the
        pointer before the pattern was matched, ``pos`` is the
        end position.
