+2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/scan-gram.l: Remove unused declaration of last_string_1 so the
+ build succeeds when configured with --enable-gcc-warnings.
+
+2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/parse-gram.y (char_name): New function.
+ (CHAR, STRING, string_content): For %printer, properly escape.
+ (ID): Prefer fputs to fprintf.
+ (id): Reindent to be consistent with other rules.
+ Properly quote char.
+
+ The Translation Project changed its way of publishing translations
+ to maintainers. I haven't received any responses to my request
+ for supporting the old way, or for documenting the new way. I
+ have modified 'bootstrap' to use screen scraping
+ (in this case, HTML scraping). This is unreliable and inelegant,
+ but I don't see any better way. Yuck.
+ * bootstrap (TP_URL, WGET_COMMAND): New vars.
+ (get_translations): New function, which uses HTML scraping to
+ deduce locations of latest translations.
+ Use this function to grab both bison and bison-runtime .po files.
+ Don't bother priming the pump for the runtime-po domain any more,
+ as it's now translated better than bison is.
+
+2006-06-19 Akim Demaille <akim@epita.fr>
+
+ * src/scan-gram.l: No longer "parse" things after `%union' until
+ `{'. Rather, return a single "%union" token.
+ No longer make symbols: return strings, and leave the conversion
+ to symbols to the parser.
+ (SC_PRE_CODE, token_type): Remove.
+ * src/parse-gram.y (%union): New field `character'.
+ Sort tokens.
+ (CHAR): New token.
+ (ID, ID_COLON): Now that the scanner no longer makes them
+ identifiers, adjust all uses to invoke symbol_get.
+ (id_colon): New, wraps the conversion from string to symbol.
+ (%union): Accept a possible union_name.
+ (symbol): Now can be a char.
+ * data/c.m4 (b4_union_name): Leave a default value.
+ * data/glr.c, data/yacc.c: Use it.
+
+2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ For associating token numbers with token names for "yacc.c", don't use
+ #define statements unless `--yacc' is specified; always use enum
+ yytokentype. Most important discussions start at:
+ <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
+ <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
+ and
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
+ * NEWS (2.3+): Mention.

+ (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
+ token #define's.
+ * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
+ on token name definitions.
+ * src/getargs.c (usage): Capitalize `Yacc' in English.
+ * src/output.c (prepare): Define b4_yacc_flag.
+ * tests/regression.at (Early token definitions): Test that tokens names
+ are defined before the pre-prologue not just before the post-prologue.
+ Remove this test case and copy to...
+ (Early token definitions with --yacc): ... this to test #define's.
+ (Early token definitions without --yacc): ... and this to test enums.
+
+2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Reword the post-2.3 change to not be so optimistic about
+ removing the old "look-ahead" spelling.
+ Update previous look-ahead/lookahead change reports.
+ * REFERENCES: look-ahead -> lookahead (since that's
+ what he actually wrote).
+ * doc/refcard.tex: look ahead -> lookahead,
+ look-ahead -> lookahead
+
+2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ For consistency, use `lookahead' instead of `look-ahead' or

+
+2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>

+
+2006-06-06 Akim Demaille <akim@epita.fr>
+
+ Extract the parsing of user actions from the grammar scanner.
+ As a consequence, the relation between the grammar scanner and
+ parser is much simpler. We can also split "composite tokens" back
+ into simple tokens.
+ * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
+ * src/scan-gram.l (add_column_width, adjust_location): Move to and
+ rename as...
+ * src/location.h, src/location.c (add_column_width)
+ (location_compute): these.
+ Fix the column count: the initial column is 0.
+ (location_print): Be robust to ending column being 0.
+ * src/location.h (boundary_set): New.
+ * src/main.c: Adjust to scanner_free being renamed as
+ gram_scanner_free.
+ * src/output.c: Include scan-code.h.
+ * src/parse-gram.y: Include scan-gram.h and scan-code.h.
+ Use boundary_set.
+ (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
+ (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
+ which is now, again, a separate token.
+ Adjust all dependencies.
+ Whereever actions with $ and @ are used, use translate_code.
+ (action): Remove this nonterminal which is now useless.
+ * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
+ (grammar_current_rule_action_append): Use translate_code.
+ (packgram): Bound check ruleno, itemno, and rule_length.
+ * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)

+ * tests/regression.at: Adjust the error message.
+
+2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.

+
+2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Between Bison releases, manually append `+' to the previous Bison
+ release number, and use that as a signal to automatically print the
+ ChangeLog's CVS Id keyword from --version. Discussed starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
+ * ChangeLog: Add Id header.
+ * configure.ac (AC_INIT): Append `+' to `2.3'.
+ * src/.cvsignore: Add revision.c.
+ * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
+ (BUILT_SOURCES): Add revision.c.
+ (revision.c): New target rule. This file defines a new global variable
+ named revision. It initializes it with either the Id from ChangeLog
+ or, if VERSION doesn't contain `+', with the empty string.
+ * src/getargs.c (version): Print the value of revision.
+ * src/revision.h: Extern revision.
+
+2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Version 2.3.
+ * configure.ac (AC_INIT): Likewise.
+
+2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c (YYRECOVERING): Define to be a function-like macro
+ with no arguments, not as an object-like macro. This is for
+ compatibility with data/yacc.c. Problem reported by John P. Hartmann in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
+ * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
+ Document this.
+
+2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/getargs.c (usage): Back out yesterday's modification of the
+ --help output so that we don't have to wait for translation before
+ releasing 2.3.
+
+2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
+
+ * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
+ Problem reported by Akim Demaille.
+
+2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
+
+2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/yacc.c (yy_reduce_print): Omit trailing white space in
+ generated source code. Problem reported by Frans Englich in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
+
+2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
+
+ * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
+ shell, not within 'make', so that 'make' by an ordinary builder
+ (using GNU make) does not worry about configuring gzip. This also
+ works around a bug reported independently by Keith Thompson and by
+ Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
+ stderr rather than stdout, messing up the build logs.
+
+2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
+ to make sure that YYID will never be unused. This fixes a 'make
+ maintainer-check' failure caused by the recent changes to the 'Trivial
+ grammars' test case, which caused g++ 4.1.0 to complain that YYID was
+ not used.
+ * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
+
+2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
+ state before an empty RHS is always resolved here. Only the location
+ of that state is guaranteed to be resolved, and that's enough. This
+ fixes the remaining bug reported by Derek M. Jones in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
+ * tests/glr-regression.at (Uninitialized location when reporting
+ ambiguity): Test the above case.
+ Also, the embedded comments in this test case claim it checks the case
+ of an empty RHS that has inherited the initial location. However, the
+ corresponding LHS was already resolved, so yyresolveLocations didn't
+ actually have reason to modify it. Fix this by forcing
+ nondeterministic operation at the beginning of the parse.
+
+2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/c.m4 (b4_yy_symbol_print_generate):
+ (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
+ 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
+ of the bugs reported today by Derek M Jones in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
+ * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
+ defined to be a type name without parens or brackets.
+ (Location Type): Similarly for YYLTYPE.
+ * tests/regression.at (Trivial grammars): Put in a test for this
+ bug that will be caught by 'make maintainer-check' (though not,
+ alas, by 'make check' unless your compiler is picky).
+
+2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Version 2.2.
+ * configure.ac (AC_INIT): Likewise.
+
+2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/glr.c (yyreportTree): Make room in yystates for the state
+ preceding the RHS. This fixes the segmentation fault reported by Derek
+ M. Jones in
+ <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
+ (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
+ to the user. Reported for yyreportTree by Derek M. Jones later in the
+ same thread.
+ * THANKS: Add Derek M. Jones.
+ Update my email address.
+ Fix typo in Steve Murphy's name.
+
+2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
+ checking against YYLAST that caused the parser to miss a potential
+ alternative in its diagnostic.
+ Problem reported by Maria Jose Moron Fernandez in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
+ * data/lalr1.cc (yysyntax_error_): Likewise.
+ * data/yacc.c (yysyntax_error): Likewise.
+ * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
+ tokens, in case we run into an older C compiler.
+ (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
+ Use them to check for the off-by-one error fixed above.
+
+ * data/yacc.c (yytnamerr): Fix typo: local var should be of type
+ YYSIZE_T, not size_t.
+ * tests/regression.at (Trivial grammars): New test, to catch
+ the error fixed by the above patch.
+
+2006-05-14 Akim Demaille <akim@lrde.epita.fr>
+
+ * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
+ scheme.
+ Reported by Steve Murphy.
+
+2006-05-14 Akim Demaille <akim@lrde.epita.fr>
+
+ * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
+ * data/glr.cc: b4_location_flag is now b4_locations_flag.
+
+2006-05-14 Akim Demaille <akim@lrde.epita.fr>
+
+ Implement --trace=m4.
+ * src/getargs.c (trace_types, trace_args): Accept trace_m4.
+ * src/output.c (output_skeleton): When set, pass -dV to m4.
+
+ Factor the handling of flags in m4.
+ * src/output.c (prepare): Rename the muscle names debug, defines,
+ error_verbose to debug_flag, defines_flag, error_verbose_flag.
+ * data/c.m4: Adjust.
+ (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
+ Use b4_define_flag_if to define other b4_FLAG_if macros.
+ (b4_location_if): As a consequence, rename as...
+ (b4_locations_if): this, for consistency.
+ Adjust all the skeletons.
+
+2006-05-14 Akim Demaille <akim@lrde.epita.fr>
+

+
+2006-05-14 Akim Demaille <akim@lrde.epita.fr>
+
+ * src/output.h, src/output.c (error_verbose): Move to...

+ Sort the flags.
+ Adjust dependencies.
+
+2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/c.m4 (b4_copyright): Put the special exception for Bison
+ skeletons here, so we don't have to put it in each skeleton. All
+ uses changed. Suggested by Akim Demaille. Also, wrap the
+ copyright notice, in case it is longer than 80 columns. Replace
+ comma by newline after title.
+
+2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
+
+ * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an

+2006-05-11 Akim Demaille <akim@lrde.epita.fr>
+
+ * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
+ with the member "token".
+ Reported by Martin Nylin.
+
+2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c: Switch to Bison 2.2 special-exception language in
