135
136	* yacc.1: note that yacc ignores -y
137
138	* main.c: add -s option to usage message.
139
140	* test/quote_calc3.output, test/quote_calc3.tab.c, test/quote_calc4.output, test/quote_calc4.tab.c, test/quote_calc4.tab.h, test/quote_calc3.y, test/quote_calc.tab.h, test/quote_calc.output, test/quote_calc.tab.c, test/quote_calc2.output, test/quote_calc2.tab.c, test/quote_calc2.tab.h, test/quote_calc3.tab.h, test/quote_calc4.y, test/quote_calc.y, test/quote_calc2.y:

146
1472011-12-19  Thomas E. Dickey  <tom@invisible-island.net>
148
149	* package/debian/changelog, package/byacc.spec, VERSION: bump
150
151	* yacc.1, output.c, main.c, defs.h:
152	add "-s" option to suppress generating #define's based on string contents
153	in a %token statement.  For instance
154		%token EQLS "Equals"
155	would generate
156		#define EQLS 256
157		#define Equals 257
158	Simply suppressing the second #define makes the behavior closer to yacc.
159	(report by Paulo Andrade).

274
275	* main.c:
276	start revising use of tmpfile(), to make this work with MinGW.  Start by

291
2922010-11-26  Thomas E. Dickey  <tom@invisible-island.net>
293
294	* skeleton.c: typo
295
296	* output.c:
297	correct line-numbering when "-r" option is used; the 'outline' variable
298	should only be incremented when writing to the code-file.
299
300	* test/code_calc.code.c, test/code_error.code.c: regen
301

308
309	* output.c:
310	improve on YYERROR_DECL(), adding dummy params which can be used for the
311	actual function declaration.  Also add YYERROR_CALL().  The two macros
312	simplify maintaining sets of grammars which may/may not be pure.

314	* test/calc1.y, test/ftp.tab.c, test/grammar.tab.c, test/pure_calc.tab.c, test/pure_error.tab.c, test/calc.tab.c, test/calc1.tab.c, test/calc2.tab.c, test/calc3.tab.c, test/code_calc.code.c, test/code_error.code.c, test/error.tab.c:
315	regen
316

320
321	* skeleton.c, defs.h: generate yyerror() calls in output.c
322
323	* output.c: simplified a little, using putc_code() and putl_code()

462	* test/pure_calc.tab.c, test/pure_error.tab.c: RCS_BASE
463
464	* test/run_test.sh:
465	provide for testing -r and -P options by checking if the ".y" filename
466	begins with "code_" or "pure_", respectively.
467
468	* test/code_error.code.c, test/code_error.tab.c, test/code_error.tab.h, test/code_calc.code.c, test/code_calc.tab.c, test/code_calc.tab.h, test/pure_calc.output, test/pure_calc.tab.h, test/pure_error.output, test/pure_error.tab.h, test/code_calc.output, test/code_error.output:

4802010-06-07  Andres.Mejia
481
482	* main.c, output.c, reader.c, defs.h, skeleton.c:
483	Fix the output order of the generated parse code file.  This allows for
484	the use of YYPARSE_PARAM, by having the output that checks for
485	YYPARSE_PARAM to be defined come after the C code block in the
486	definitions section of a yacc file.
487
488	Implement support for YYLEX_PARAM, similar to bison.  This is useful for
489	support for building reentrant lexers with flex.
490
491	Fix a compatibility issue with bison's pure-parser option.  Bison
492	defines yylex as sending at least one parameter, &yylval, as the first
493	parameter and doesn't seem to have an easy way to remove that parameter.
494	This on the other hand is rather convenient to support saving to yylval
495	from flex when building reentrant lexers and parsers.
496
497	Add support for the %parse-param and %lex-param directives used in
498	bison.  This change bears some similarity to NetBSD's changes to byacc
499	at http://www.mail-archive.com/source-changes-full@netbsd.org/msg08143.html
500
501	Bison allows for POSIX yacc emulation via a yacc directive in the yacc
502	file, and also via a command line switch.  Implement this feature as a
503	no-op for byacc, since byacc is designed to be POSIX yacc compatible
504	anyway.  This allows for better compatibility with yacc sources written
505	for bison.
506
5072010-06-07  Thomas E. Dickey  <tom@invisible-island.net>
508
509	* VERSION: bump to 2010/06/07
510

512
513	* test/calc.tab.c, configure: regen
514
515	* skeleton.c:

532
533	* makefile.in: add etags/TAGS if available
534
535	* configure.in: add configure check for actual ctags and etags programs

569	* yacc.1: document -P and bison-extensions
570
571	* test/ftp.tab.c, test/grammar.tab.c, test/calc.tab.c, test/error.tab.c:
572	regen
573
574	* output.c: implement %pure-parser
575
576	* skeleton.c:
577	implement %pure-parser, like bison.  To help with this, changed the stack
578	variables, putting them into a struct.
579
580	* reader.c: implement %pure-parser
581
582	* defs.h: modified skeleton to support %pure-parser feature
583
584	* main.c: add -P option to set %pure-parser
585
586	* output.c:
587	make -r and -p options work together.  The -r option splits the generated
588	parser into code/table files; for this case we cannot use static data.
589	Also, we have to repeat the #define's used for prefix (-p) as well as the
590	redeclaration of yyparse().  Finally, allow any of the prefixed names to
591	be overridden, e.g., by passing a -D option to the compiler.  Make that
592	a little more readable by putting a blank line before each chunk.
593
594	* defs.h: add definitions for %pure-parser
595
596	* skeleton.c:
597	put blank line before/after the redeclaration of yyparse()
598
599	* output.c: allow for other program redefining yylex()
600
601	* skeleton.c:
602	split-off xdecls[] array, to move declaration of yyparse() after #define's
603
604	* defs.h: split-out xdecls[]
605
606	* VERSION: bump
607
608	* configure: regen

908	* skeleton.c:
909	move the actual definition of YYMAJOR and YYMINOR to defs.h (as numbers).
910	add YYPATCH here so it can be tested by applications.

916	* lalr.c, lr0.c, mkpar.c, defs.h, closure.c, warshall.c, output.c, verbose.c, graph.c, reader.c, main.c, symtab.c:
917	reduce externs by making static the procedures that are not referenced outside
918	the module in which they are defined.
919
920	* makefile.in:
921	the VERSION file holds the patch-date.  Define YYPATCH, so this will be
922	compiled into the skeleton.
923
924	* VERSION: patch-level for byacc
925
926	* main.c:
927	add "-o" to usage message.  It is too long for a single line; rewrite usage()
928	to show one option per line.
929
9302005-05-03  Thomas E. Dickey  <tom@invisible-island.net>
931
932	* main.c: add -o option, to work with scripts that assume bison.
933	simplify create_file_names() with a macro.
934	simplify done() with a macro.

936	onintr(), do not flush output via exit(), but use _exit() instead.
937
938	* defs.h: remove unnecessary externs for main.c
939
940	* yacc.1: add -o option
941
942	* graph.c: remove unused parameter

976
977	* test/calc.tab.c, test/error.tab.c, test/ftp.tab.c, test/grammar.tab.c:
978	updates due to adding yyparse() prototype
979
980	* configure: RCS_BASE
981
982	* configure.in:
983	add AC_ARG_PROGRAM to make --program-prefix, etc., work.
984
985	* makefile.in: first cut of script to support --program-prefix
986
987	* configure.in:
988	reorder AC_INIT/AC_CONFIG_HEADER to make this "work" with autoconf 2.52
989
990	* makefile.in: modify so DESTDIR works
991
992	* makefile.in: use EXEEXT and OBJEXT
993
994	* configure.in: use CF_PROG_EXT
995	generate a config.h
996
997	* defs.h: make this use the generated config.h
998
999	* skeleton.c: add a forward-reference for yyparse()
1000
1001	* aclocal.m4: add CF_CHECK_CACHE, needed for CF_PROG_EXT
1002
1003	* yacc.1: remove the discussion of TMPDIR since it is obsolete
1004
1005	* skeleton.c: fix a couple of minor compiler-warnings in the skeleton
1006
1007	* defs.h: remove action_file_name, etc., since we use tmpfile() now.
1008
1009	* main.c:
1010	use tmpfile() for opening the working files.  This quiets a warning
1011	advising the use of mkstemp().
1012
1013	* output.c:
1014	Do not close temporary-files here, since they are opened with tmpfile().
1015	Just rewind them, and they're ready to read back the data stored in them.
1016
