Parser

abstract class abjad.system.Parser.Parser(debug=False)

Abstract base class for Abjad parsers.

Rules objects for lexing and parsing must be defined by overriding the abstract properties lexer_rules_object and parser_rules_object.

For most parsers these properties should simply return self.
