#define statements unless `--yacc' is specified; always use enum yytokentype. Most important discussions start at: <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>, <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>, and <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>. * NEWS (2.3+): Mention. * data/c.m4 (b4_yacc_if): New. (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the token #define's. * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc' on token name definitions. * src/getargs.c (usage): Capitalize `Yacc' in English. * src/output.c (prepare): Define b4_yacc_flag. * tests/regression.at (Early token definitions): Test that tokens names are defined before the pre-prologue not just before the post-prologue. Remove this test case and copy to... (Early token definitions with --yacc): ... this to test #define's. (Early token definitions without --yacc): ... and this to test enums.
-*- outline -*- This directory contains Bison skeletons: the general shapes of the different parser kinds, that are specialized for specific grammars by the bison program. Currently, there are only three supported skeletons: - yacc.c It used to be named bison.simple: it corresponds to C Yacc compatible LALR(1) parsers. - lalr1.cc Produces a C++ parser class. It is still very experimental, and not yet supported. Please, subscribe to bison-patches@gnu.org. - glr.c A Generalized LR C parser based on Bison's LALR(1) tables. These skeletons are the only ones supported by the Bison team. Because the interface between skeletons and the bison program is not finished, *we are not bound to it*. In particular, Bison is not mature enough for us to consider that ``foreign skeletons'' are supported. ----- Copyright (C) 2002 Free Software Foundation, Inc. This file is part of GNU Bison.
