In the case a user wants to create location.hh elsewhere, it can be helpful to define api.location.file to some possibly absolute path such as -Dapi.location.file='"$(top_srcdir)/include/ast/location.hh"'. Currently this does not work with `-o foo/parser.cc`, as we join foo/ and $(top_srcdir) together, the latter starting with slash. We should not try to do that in m4, manipulating file names is quite complex when you through Windows file name in. Let m4 delegate this to gnulib. * src/scan-skel.l (at_output): Accept up to two arguments. * data/bison.m4 (b4_output): Adjust. * tests/skeletons.at (Fatal errors but M4 continues producing output): Adjust to keep the error. * data/location.cc, data/stack.hh: Leave the concatenation to @output. * tests/output.at: Exercise api.location.file with an absolute path.
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.
