A header file is also be generated, and contains -the token list. - -The options are: - -``COMPILE_FLAGS <flags>`` - Specify flags to be added to the ``bison`` command line. - -``DEFINES_FILE <file>`` - Specify a non-default header ``<file>`` to be generated by ``bison``. - -``VERBOSE [<file>]`` - Tell ``bison`` to write a report file of the grammar and parser. - If ``<file>`` is given, it specifies path the report file is copied to. - ``[<file>]`` is left for backward compatibility of this module. - Use ``VERBOSE REPORT_FILE <file>``. - -``REPORT_FILE <file>`` - Specify a non-default report ``<file>``, if generated. - -The macro defines the following variables: - -``BISON_<Name>_DEFINED`` - ``True`` is the macro ran successfully - -``BISON_<Name>_INPUT`` - The input source file, an alias for <YaccInput> - -``BISON_<Name>_OUTPUT_SOURCE`` - The source file generated by bison - -``BISON_<Name>_OUTPUT_HEADER`` - The header file generated by bison - -``BISON_<Name>_OUTPUTS`` - All files generated by bison including the source, the header and the report - -``BISON_<Name>_COMPILE_FLAGS`` -
