ChangeLog

   1 2000-10-02  Akim Demaille  <akim@epita.fr>
   2
   3         * src/getargs.c (getargs): Don't dump `--help' on unrecognized
   4         options.
   5
   6 2000-10-02  Akim Demaille  <akim@epita.fr>
   7
   8         * src/derives.c, src/print.c, src/reduce.c: To ease the
   9         translation, move some `\n' out of the translated strings.
  10
  11 2000-10-02  Akim Demaille  <akim@epita.fr>
  12
  13         The location tracking mechanism is precious for parse error
  14         messages.  Nevertheless, it is enabled only when `@n' is used in
  15         the grammar, which is a different issue (you can use it in error
  16         message, but not in the grammar per se).  Therefore, there should
  17         be another means to enable it.
  18
  19         * src/getargs.c (getargs): Support `--locations'.
  20         (usage): Report it.
  21         * src/getargs.h (locationsflag): Export it.
  22         * src/lex.c (percent_table): Support `%locations'.
  23         * src/reader.c (yylsp_needed): Remove this variable, now replaced
  24         with `locationsflag'.
  25         * doc/bison.texinfo: Document `--locations' and `%locations'.
  26         Sort the options.
  27         * tests/calc.m4: Test it.
  28
  29         For regularity of the names, replace each
  30         (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
  31         (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
  32         In addition replace each `flag' with `_flag'.
  33
  34 2000-10-02  Akim Demaille  <akim@epita.fr>
  35
  36         Also test parse error messages, including with YYERROR_VERBOSE.
  37
  38         * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
  39         associative).
  40         Use it to check the computations.
  41         Use it to check `nonassoc' is honored.
  42         (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
  43         `--yyerror-verbose'.
  44         (_AT_CHECK_CALC): Adjust to this option.
  45         (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
  46
  47 2000-10-02  Akim Demaille  <akim@epita.fr>
  48
  49         Test also `--verbose', `--defines' and `--name-prefix'.  Testing
  50         the latter demonstrates a flaw in the handling of non debugging
  51         parsers introduced by myself on 2000-03-16: `#define yydebug 0'
  52         was used in order to simplify:
  53
  54         #if YYDEBUG
  55         if (yydebug)
  56         {
  57         ...
  58         }
  59         #endif
  60
  61         into
  62
  63         if (yydebug)
  64         {
  65         ...
  66         }
  67
  68         unfortunately this leads to a CPP conflict when
  69         `--name-prefix=foo' is used since it produces `#define yydebug
  70         foodebug'.
  71
  72         * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
  73         (YYDPRINTF): New macro.
  74         Spread its use.
  75         * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
  76         the bison options.
  77         Also test `--verbose', `--defines' and `--name-prefix'.
  78
  79 2000-10-02  Akim Demaille  <akim@epita.fr>
  80
  81         Improve the readability of the produced parsers.
  82
  83         * src/bison.s1: Formatting changes.
  84         Improve the comment related to the `$' mark.
  85         (yydefault): Don't fall through to `yyresume': `goto' there.
  86         * src/output.c (output_parser): When the `$' is met, skip the end
  87         of its line.
  88         New variable, `number_of_dollar_signs', to check there's exactly
  89         one `$' in the parser skeleton.
  90
  91 2000-10-02  Akim Demaille  <akim@epita.fr>
  92
  93         * lib/xstrdup.c: New file, from the fileutils.
  94         * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
  95         (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
  96         instead of strlen + xmalloc + strcpy.
  97         * src/symtab.c (copys): Remove, use xstrdup instead.
  98
  99 2000-10-02  Akim Demaille  <akim@epita.fr>
 100
 101         * src/gram.h (associativity): New enum type which replaces the
 102         former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
 103         `right_assoc', `left_assoc' and `non_assoc'.
 104         Adjust all dependencies.
 105         * src/reader.c: Formatting changes.
 106         (LTYPESTR): Don't define it, use it as a literal in
 107         `reader_output_yylsp'.
 108         * src/symtab.h (symbol_class): New enum type which replaces the
 109         former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
 110         `sunknown', `stoken and `snterm'.
 111
 112 2000-10-02  Akim Demaille  <akim@epita.fr>
 113
 114         * src/getargs.c (fixed_outfiles): Rename as...
 115         (yaccflag): for consistency and accuracy.
 116         Adjust dependencies.
 117
 118 2000-10-02  Akim Demaille  <akim@epita.fr>
 119
 120         Use the more standard files `xalloc.h' and `xmalloc.c' instead of
 121         Bison's `allocate.c' and `alloc.h'.  This patch was surprisingly
 122         difficult and introduced a lot of core dump.  It turns out that
 123         Bison used an implementation of `xmalloc' based on `calloc', and
 124         at various places it does depend upon the initialization to 0.  I
 125         have not tried to isolate the pertinent places, and all the former
 126         calls to Bison's `xmalloc' are now using `XCALLOC'.  Someday,
 127         someone should address this issue.
 128
 129         * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
 130         * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
 131         files.
 132         Adjust dependencies.
 133         * src/warshall.h: New file.
 134         Propagate.
 135
 136 2000-10-02  Akim Demaille  <akim@epita.fr>
 137
 138         Various anti-`extern in *.c' changes.
 139
 140         * src/system.h: Include `assert.h'.
 141
 142 2000-10-02  Akim Demaille  <akim@epita.fr>
 143
 144         * src/state.h (nstates, final_state, first_state, first_shift)
 145         (first_reduction): Move their exportation from here...
 146         * src/LR0.h: to here.
 147         Adjust dependencies.

 155
 156         * src/LR0.h: New file.

 195         (xfopen, xfclose, open_files): this.
 196         (stringappend): static.
 197         * src/files.h: Complete the list of exported symbols.

 201
 202         * src/reader.h: New file.
 203         Propagate its use instead of tedious list of `extern' and

 222 2000-10-02  Akim Demaille  <akim@epita.fr>
 223
 224         * src/output.c (token_actions): Introduce a temporary array,
 225         YYDEFACT, that makes it possible for this function to use
 226         output_short_table.
 227
 228 2000-10-02  Akim Demaille  <akim@epita.fr>
 229
 230         `user_toknums' is output as a `short[]' in `output.c', while it is
 231         defined as a `int[]' in `reader.c'.  For consistency with the
 232         other output tables, `user_toknums' is now defined as a table of
 233         shorts.
 234
 235         * src/reader.c (user_toknums): Be a short table instead of an int
 236         table.

 244
 245 2000-10-02  Akim Demaille  <akim@epita.fr>
 246
 247         * src/output.c (output): Topological sort of the functions, in
 248         order to get rid of the `static' prototypes.
 249         No longer use `register'.
 250         * src/output.h: New file.
 251         Propagate its inclusion in files explicitly prototyping functions
 252         from output.c.
 253
 254 2000-09-21  Akim Demaille  <akim@epita.fr>
 255
 256         * src/atgeneral.m4: Update from Autoconf.
 257

 259
 260         * src/closure.h: New file.
 261         * src/closure.c: Formatting changes, topological sort over the
 262         functions, use of closure.h.
 263         (initialize_closure, finalize_closure):  Rename as...
 264         (new_closure, free_closure): these.  Adjust dependencies.
 265         * src/LR0.c: Formatting changes, topological sort, use of
 266         cloture.h.
 267         (initialize_states): Rename as...
 268         (new_states): this.
 269         * src/Makefile.am (noinst_HEADERS): Adjust.
 270
 271 2000-09-20  Akim Demaille  <akim@epita.fr>
 272
 273         * src/acconfig.h: Don't protect config.h against multiple
 274         inclusion.
 275         Don't define PARAMS.
 276         * src/system.h: Define PARAMS.
 277         Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
 278         purpose of config.h.  system.h must not try to fix wrong
 279         definitions in config.h.
 280
 281 2000-09-20  Akim Demaille  <akim@epita.fr>
 282

 293         Use these macros to test bison with options `', `--raw',
 294         `--debug', `--yacc', `--yacc --debug'.
 295
 296 2000-09-19  Akim Demaille  <akim@epita.fr>
 297
 298         * src/output.c: Formatting changes.
 299         * src/machine.h: Remove, leaving its contents in...
 300         * src/system.h: here.
 301         Include stdio.h.
 302         Adjust all dependencies on stdio.h and machine.h.
 303         * src/getargs.h: New file.
 304         Let all `extern' declarations about getargs.c be replaced with

 307
 308         * tests/calc.m4 (yyin): Be initialized in main, not on the global

 319
 320         * configure.in: Append WARNING_CFLAGS to CFLAGS.
 321         * src/Makefile.am (INCLUDES): Don't.
 322         Be ready to fetch headers in lib/.
 323
 324 2000-09-18  Akim Demaille  <akim@epita.fr>
 325
 326         * doc/bison.texinfo: Update the copyright.
 327         ANSIfy and GNUify the examples.

 329
 330 2000-09-18  Akim Demaille  <akim@epita.fr>

 333
 334         * src/bison.s1 (yyparse): Condition the code using `yytname' which
 335         is defined only when YYDEBUG is.

 365         (get_type, parse_start_decl): Use the same `invalid' message.

 439
 440         * src/Makefile.am (bison.simple): Fix the awk program: quote only
 441         the file name, not the whole `#line LINE FILE'.
 442
 443 2000-03-17  Akim Demaille  <akim@epita.fr>

 465
 466         * src/reader.c (copy_definition): Use copy_string and
 467         copy_comment.  Removed now unused `match', `ended',
 468         `cplus_comment'.
 469         (copy_comment, copy_string): Moved, to be visible from

 496
 497         Change the handling of @s so that they behave exactly like $s.
 498         There is now a pseudo variable @$ (readble and writable), location
 499         of the lhs of the rule (by default ranging from the location of
 500         the first symbol of the rhs, to the location of the last symbol,
 501         or, if the rhs is empty, YYLLOC).
 502

 504         yyval.
 505         (yyparse): When providing a default semantic action, provide a
 506         default location action.
 507         (after the $): No longer change `*YYLSP', just stack YYLOC the
 508         same way you stack YYVAL.
 509         * src/reader.c (read_declarations): Use warns.
 510         (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.

 512         Use a standard error message, to save useless work from
 513         translators.
 514
 515 2000-03-17  Akim Demaille  <akim@epita.fr>
 516

 534
 535         * src/bison.s1 [!YYDEBUG]: Define yydebug to 0.  This allows to
 536         remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
 537         One `#if YYDEBUG' remains, since it uses variables which are
 538         defined only if `YYDEBUG != 0'.
 539
 540 2000-03-16  Akim Demaille  <akim@epita.fr>
 541
 542         * src/bison.s1 (yyparse): Reorganize the definitions of the stacks

 564         handled via src/Makefile.am.
 565         (VERSION_STRING, PROTOTYPES, ENABLE_NLS, HAVE_CATGETS,
 566         HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by

 574         locale files.
 575         (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
 576         builddir.
 577         * acinclude.m4: Remove, replaced by the directory m4.
 578         * m4/Makefile.am (EXTRA_DIST): New variable.
 579         * m4/gettext.m4: New file, from the fileutils.

1190 1995-10-16  Richard Stallman  <rms@gnu.org>
1191
1192         * doc/bison.1, doc/bison.rnh:
1193         Add new options.
1194
1195 1995-10-15  Richard Stallman  <rms@gnu.org>
1196
1197         * src/vmsgetargs.c, src/getargs.c:
1198         Added -n, -k, and -raw switches.

1211         (readgram): Use `#if 0' around code that accepted %command
1212         inside grammar rules:  The documentation doesn't allow it,
1213         and it will fail since the %command processors scan for the next %.
1214         (parse_token_decl):  Extended the %token
1215         declaration to allow a multi-character symbol as an alias.
1216         (parse_thong_decl): New function.

1224         (get_type_name, copy_guard, copy_action, readgram)
1225         (get_type, packsymbols):  Revised most error messages.
1226         Changed `fatal' to `warnxxx' to avoid aborting for error.
1227         Revised and use multiple warnxxx functions to avoid using VARARGS1.
1228         (read_declarations): Improve the error message for
1229         an invalid character.  Do not abort.
1230         (read_declarations, copy_guard, copy_action): Use
1231         printable_version to avoid unprintable characters in printed output.
1232         (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
1233         (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
1234         Allow the type of a non-terminal can be given
1235         more than once, as long as all specifications give the same type.
1236
1237         * src/output.c:
1238         (output_headers, output_trailers, output, output_gram)
1239         (output_rule_data): Implement noparserflag variable.
1240         Implement toknumflag variable.
1241         (output): Call reader_output_yylsp to output LTYPESTR.
1242
1243         * src/main.c (main):
1244          If reader sees an error, don't process the grammar.
1245         (fatals): Updated to not use VARARGS1.
1246         (printable_version, int_to_string, warn, warni, warns, warnss)
1247         (warnsss): New error reporting functions.  Avoid abort for error.
1248
1249         * src/lex.h:
1250         Added THONG and NOOP for alias processing.
1251         Added SETOPT for the new code that allows setting options with %flags.
1252
1253         * src/lex.c:
1254         Include getopt.h.  Add some extern decls.
1255         (safegetc): New function to deal with EOF gracefully.
1256         (literalchar); new function to deal with reading \ escapes.
1257         (lex): Use literalchar.
1258         (lex): Implemented "..." tokens.
1259         (literalchar, lex, parse_percent_token): Made tokenbuffer
1260         always contain the token.  This includes growing the token
1261         buffer while reading an integer.
1262         (parse_percent_token): Replaced if-else statement with percent_table.
1263         (parse_percent_token): Added % declarations as another
1264         way to specify the flags -n, -l, and -r.  Also added hooks for
1265         -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
1266         major changes to files.c.
1267         (lex) Retain in the incoming stream a character following
1268         an incorrect '/'.
1269         (skip_white_space, lex):  Revised most error messages
1270         and changed fatal to warn to avoid aborting.
1271         (percent_table):  Added %thong declarations.
1272
1273         * src/gram.h: Comment changes.
