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. :copyright: Copyright 2006-2023 by the Pygments team, see AUTHORS. :license: BSD, see LICENSE for details. � Nc � � e Zd ZdZy)� EndOfTextzZ Raise if end of text is reached and the user tried to call a match function.

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.
