%end-header. Don't use these declarations to separate pre-prologue blocks from post-prologue blocks. Add new order-independent declarations %before-header and %after-header as alternatives to the traditional Yacc pre-prologue and post-prologue blocks. Discussed at <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>. * NEWS (2.3+): Update for these changes. * data/glr.c (b4_before_definitions): Update to... (b4_start_header): ... this. (b4_after_definitions): Update to... (b4_end_header): ... this. * data/glr.cc: Likewise. * data/lalr1.cc: Likewise. * data/yacc.c: Likewise. * doc/bison.texinfo (The prologue): Update names, and replace remaining prologue blocks with %*-header declarations. (Calc++ Parser): Likewise. (Bison Declaration Summary): Update names. (Bison Symbols): Update description. * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to... (PERCENT_END_HEADER): ... this. (PERCENT_BEFORE_DEFINITIONS): Update to... (PERCENT_START_HEADER): ... this. (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens. (declaration): Update token names and m4 macro names. When parsing %end-header and %start-header, invoke translate_code before muscle_code_grow, and no longer set global booleans to remember whether these declarations have been seen. Parse new %after-header and %before-header. * src/reader.c (before_definitions, after_definitions): Remove. (prologue_augment): Accept a new bool argument to specify whether to augment the pre-prologue or post-prologue. * src/reader.h (before_definitions, after_definitions): Remove these extern's. (prologue_augment): Add new bool argument. * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to... (PERCENT_END_HEADER): ... this. (PERCENT_BEFORE_DEFINITIONS): Update to... (PERCENT_START_HEADER): ... this. (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens. * tests/actions.at (Printers and Destructors): Update names.
-*- 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.
