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 + + * 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 + + 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 + . + * 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.

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 + + * NEWS: Version 2.3. + * configure.ac (AC_INIT): Likewise. + +2006-05-30 Paul Eggert + + * 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 + . + * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols): + Document this. + +2006-05-30 Joel E. Denny + + * 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 + + * doc/bison.texinfo (Introduction): Don't say "GLR grammar". + Problem reported by Akim Demaille. + +2006-05-29 Joel E. Denny + + * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output. + +2006-05-26 Paul Eggert + + * data/yacc.c (yy_reduce_print): Omit trailing white space in + generated source code. Problem reported by Frans Englich in + . + +2006-05-22 Paul Eggert + + * 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 + + * 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 + + * 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 + . + * 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 + + * 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 + . + * 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 + + * NEWS: Version 2.2. + * configure.ac (AC_INIT): Likewise. + +2006-05-17 Joel E. Denny + + * 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 + . + (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 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in @@ -15932,3 +16299,5 @@ Copying and distribution of this file, with or without modification, are permitted provided the copyright notice and this notice are preserved. + +$Id$
