(CXX): this, to keep the original Autoconf semantics. Require 2.57. * data/lalr1.cc: Fix b4_copyright invocations. If YYDEBUG is not defined, don't depend upon name_ being defined. (location.hh): Include string and iostream. (Position::filename): New member. (Position::Position ()): New. (operator<< (Position)): New. (operator- (Position, int)): New. (Location::first, Location::last): Rename as... (Location::begin, Location::end): these, to mock the conventional iterator names. (operator<< (Location)): New. * tests/atlocal.in (CXX): New. * tests/testsuite.at (AT_COMPILE_CXX): New. * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the locations in a more synthetic way. (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if lalr1.cc is used. Adjust the C locations to match those from Emacs: first column is column 0. Change all the expected results. Conform to the GCS: simplify the locations when applicable. (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS) (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace these CPP macros with the m4 macros new defined by... (AT_CHECK_PUSHDEFS): this, i.e.: (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS) (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALSm AT_LEX_PRE_ARGS) New macros. (AT_CHECK_POPDEFS): Undefine them. (AT_CHECK_CALC_LALR1_CC): New. Use it for the first lalr1.cc test.
-*- 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.
