The files stack.hh and position.hh are deprecated. Rather than devoting specify %define variables to discard them (api.position.file and api.stack.file), and rather than having to use special rules when api.location.file is used, let's simply decide that from %require "3.2" onwards, these files will not be generated. The only noticeable thing here is that, in order to be able to check the behavior of %require "3.2", to have this version (which is still 3.1-*) to accept %require "3.2". * src/gram.h, src/gram.c (required_version): New. * src/parse-gram.y (version_check): Set it. * src/output.c (prepare): Pass it m4. * data/bison.m4 (b4_required_version_if): Receive it and use it. * data/location.cc, data/stack.hh: Replace the api.*.file with only required version comparison. * tests/input.at: No longer check api.stack.file and api.position.file. * NEWS, doc/bison.texi: Don't mention them. Document the %require 3.2 behavior. * tests/output.at: Use %require 3.2 instead.
This directory contains data needed by Bison. * Skeletons Bison skeletons: the general shapes of the different parser kinds, that are specialized for specific grammars by the bison program. Currently, the supported skeletons are: - 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. - lalr1.java Produces a Java parser class. - glr.c A Generalized LR C parser based on Bison's LALR(1) tables. - glr.cc A Generalized LR C++ parser. Actually a C++ wrapper around glr.c. 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. * m4sugar This directory contains M4sugar, sort of an extended library for M4, which is used by Bison to instantiate the skeletons. * xslt This directory contains XSLT programs that transform Bison's XML output into various formats. - bison.xsl A library of routines used by the other XSLT programs. - xml2dot.xsl Conversion into GraphViz's dot format. - xml2text.xsl Conversion into text. - xml2xhtml.xsl Conversion into XHTML. ----- Local Variables: mode: outline End: Copyright (C) 2002, 2008-2015, 2018 Free Software Foundation, Inc.
