Suggested by Joel E. Denny. http://lists.gnu.org/archive/html/bison-patches/2013-03/msg00016.html * data/bison.m4 (b4_percent_define_get_kind): New. (b4_variant_flag): Check that api.value.type is defined as the 'variant' keyword value. * data/c.m4 (_b4_value_type_setup_keyword): New. (b4_value_type_setup): Use it to simplify reading. Use b4_define_silent. Decode api.value.type, including its type. (b4_value_type_define): Likewise. * data/c++.m4 (b4_value_type_declare): Adjust the decoding of api.value.type, taking its kind into account. * doc/bison.texi: Adjust all the examples to the new syntax. * NEWS: Ditto. * tests/types.at: Adjust
-*- outline -*- 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. ----- Copyright (C) 2002, 2008-2013 Free Software Foundation, Inc.
