Before we were using tables which lines were the symbols and which columns were things like number, tag, type-name etc. It is was difficult to extend: each time a column was added, all the numbers had to be updated (you asked for colon $2, not for "tag"). Also, it was hard to filter these tables when only a subset of the symbols (say the tokens, or the nterms, or the tokens that have and external number *and* a type-name) was of interest. Now instead of monolithic tables, we define one macro per cell. For instance "b4_symbol(0, tag)" is a macro name which contents is self-decriptive. The macro "b4_symbol" provides easier access to these cells. * src/output.c (type_names_output): Remove. (symbol_numbers_output, symbol_definitions_output): New. (muscles_output): Call them. (prepare_symbols): Define b4_symbols_number.
-*- 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.
