d9df47b656 Deprecate %pure-parser and add `%define api.pure'. Discussed starting
at
<http://lists.gnu.org/archive/html/bison-patches/2007-09/msg00006.html>.
* NEWS (2.3a+): Mention.
* data/bison.m4 (b4_pure_if): Don't define it here.
* data/c.m4 (b4_identification): Depend on individual skeletons to
define b4_pure_flag, b4_push_flag, or b4_pull_flag if they use the
values of the %define variables api.pure or api.push_pull.  Define
YYPURE, YYPUSH, and YYPULL accordingly.
* data/glr.c: Define b4_pure_if based on `%define api.pure' unless
glr.cc has already defined b4_pure_flag.
* data/push.c: Define b4_pure_if based on `%define api.pure'.
Remove YYPUSH and YYPULL since they're back in b4_identification again.
* data/yacc.c Define b4_pure_if based on `%define api.pure'.
* doc/bison.texinfo (Pure Decl): Update.
(Push Decl): Update.
(Decl Summary): Add api.pure to %define entry.
In %pure-parser entry, say it's deprecated and reference %define.

d782395d52 Replace %push-parser' and %push-pull-parser' with
`%define push_pull "push"' and `%define push_pull "both"'.
`%define push_pull "pull"' is the default.
* doc/bison.texinfo (Push Decl, Push Parser Function,
Pull Parser Function, Parser Create Function, Parser Delete Function):
Update declarations.
(Decl Summary, Table of Symbols): Replace %push-parser and
%push-pull-parser entries with a %define push_pull entry.
* data/bison.m4 (b4_percent_define_check_values): New macro.
(b4_pull_if, b4_push_if, b4_use_push_for_pull_if): Move these
definitions...
* data/c.m4 (b4_identification): ... and the YYPUSH and YYPULL cpp
definitions...
* data/push.c: ... to here and compute them from the value of the
%define variable push_pull.
* data/c-skel.m4: Instead of choosing the push.c skeleton for push
parsing requests here...
* data/yacc.c: ... hack this to switch to push.c any time
b4_use_push_pull_flag or the %define variable push_pull is set.  This
will go away when we mv push.c yacc.c.
* data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
push parsing is not supported since unused %define variables are
reported anyway.
* src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.
* src/muscle_tab.h (muscle_percent_define_check_values): Update
comments for consistency with b4_percent_define_check_values.

7ecec4ddf9 Simplify union and prologue handling, and escape union and lex/parse
params with digraphs.
* data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
values to the empty string since these are no longer guaranteed
initialized by the front-end.
* data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
braces around b4_user_stype since this is no longer done by the
front-end.
* src/files.c, src/files.h (pre_prologue_obstack,
post_prologue_obstack): Remove.
* src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
comments here.  Use MUSCLE_OBSTACK_SGROW so that values are escaped
with digraphs.  This fixes lex params and parse params.
* src/muscle_tab.h (muscle_pair_list_grow): Update comments.
* src/output.c (prepare): Remove muscle insertion of the prologues.
(output): Remove freeing of pre_prologue_obstack and
post_prologue_obstack.
* src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
than prologue_augment for prologue parsing so you don't need prologue
obstacks.
(grammar_declaration): Use `braceless' instead of "{...}" so that
braces are already stripped and code is escaped with digraphs.
* src/reader.c (prologue_augment): Remove.
(reader): Remove initialization of pre_prologue_obstack and
post_prologue_obstack.
* src/reader.h (prologue_augment): Remove.

* data/c.m4: Remove stray parenthesis.

08af01c2fc Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
unreliable -- especially when they're hidden inside another macro.
* data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
data/c.m4: Remove m4_divert(-1).
* data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
m4_divert_push(0) and m4_divert_pop(0).
* data/output.c (output_skeleton): Don't add an m4_divert_push(0) and
an m4_wrap([m4_divert_pop(0)]) to the M4.  Diversion -1, which is
pushed and popped by m4sugar, should be first on the stack.

Provide warn, complain, and fatal function callbacks to the skeletons.
This provides more flexibility than m4_fatal, improves the error
message format, and captures messages for translation.  Discussed
starting at
<http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
* data/bison.m4 (b4_error): New, invoked by...
(b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
directives.  Because these M4 macros might be called when the current
diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
the previous removal of uses of m4_divert, which caused trouble.
(b4_check_percent_code_qualifiers): Use b4_complain instead of
m4_fatal to report unrecognized %code qualifiers.
* data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
push parser requests.
* data/glr.c: Use b4_complain instead of m4_fatal to report
non-deterministic push parser requests.
Update @output usage to @output(...@) form.
* data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
report missing %defines.  Update @output usage to @output(...@) form.
* data/location.cc, data/push.c, data/yacc.c: Update @output usage to
@output(...@) form.
* src/main.c (main): Invoke skel_scanner_free.
* src/scan-skel.h (skel_scanner_free): Prototype new function.
* src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
obstack_for_string from flex-scanner.h.
(YY_DECL): Use to declare skel_lex static.
(decode_at_digraphs): Remove; now handled in the new
SC_AT_DIRECTIVE_ARG start condition.
(fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
functions.
(at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
at_directive_argv): New static globals.
(INITIAL): Use fail_for_invalid_at.
Don't parse `@output file_name\n' or `@basename(...@)'.  Instead,
recognize the start of a generalized `@directive(...@)' form and
start...
(SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
directive args (using the new obstack_for_string), to decode the
contained @ diagraphs, and to perform the directive.  It recognizes
@basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
@output(...@).
(SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
`@,'.
(scan_skel): Initialize obstack_for_string on the first call.
(skel_scanner_free): New function to free obstack_for_string.
* tests/input.at (Reject bad %code qualifiers): Update test output.

7172e23e8f For push mode, convert yyparse from a macro to a function, invoke yylex
instead of passing a yylexp argument to yypull_parse, and don't
generate yypull_parse or yyparse unless %push-pull-parser is declared.
Discussed starting at
<http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
* data/bison.m4 (b4_pull_if): New.
* data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
* data/push.c: Improve M4 quoting a little.
(b4_generate_macro_args, b4_parenthesize): Remove.
(yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
any time a pull parser is requested.
Don't #define this as a wrapper around yypull_parse.  Instead, when
both push and pull are requested, make it a function that does that
same thing.
(yypull_parse): If there's a b4_prefix, #define this to
b4_prefix[pull_parse] when both push and pull are requested.
Don't define this as a function unless both push and pull are
requested.
Remove the yylexp argument and hard-code yylex invocation instead.
* etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
%push-parser.
* src/getargs.c (pull_parser): New global initialized to true.
* getargs.h (pull_parser): extern it.
* src/output.c (prepare): Insert pull_flag muscle.
* src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
(prologue_declaration): Set both push_parser and pull_parser = true for
%push-pull-parser.  Set push_parser = true and pull_parser = false for
%push-parser.
* src/scan-gram.l: Don't accept %push_parser as an alternative to
%push-parser since there's no backward-compatibility concern here.
Scan %push-pull-parser.
* tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
instead of %push-parser.
* tests/headers.at (export YYLTYPE): Make yylex static, and don't
prototype it in the module that calls yyparse.
* tests/input.at (Torturing the Scanner): Likewise.
* tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.

	b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,

34ec357927 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
rather than -W, so we don't get bogus warnings about sign comparisons.
Add -Wpointer-arith, since that warning is useful (it reports code
that does not conform to C89 and that some compilers reject).
* data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
since it's no longer needed.

06e8700a00 Suppress signed/unsigned comparison warnings for yycheck.

a signed int type, cast it to b4_safest_int_type first.
* data/yacc.c: Likewise.

b931235eb9 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:

* 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.

* 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).

327afc7c84 Implement --trace=m4.
* src/getargs.c (trace_types, trace_args): Accept trace_m4.
* src/output.c (output_skeleton): When set, pass -dV to m4.

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.

6e93d810ca * 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.  Wrap the copyright notice, in case it is longer
than 80 columns.  Replace comma by newline after title.

mandated anyway.
(AT_CHECK_CALC_GLR_CC): New.
Use it to exercise glr.cc as a lalr1.cc drop-in replacement.
2006-01-03 09:06:22 +00:00
Akim Demaille
a0af42fce6 * data/lalr1.cc, data/yacc.c, data/glr.c, data/c.m4
(b4_yysymprint_generate): Rename as...
(b4_yy_symbol_print_generate): this.
Generate yy_symbol_print instead of yysymprint.

12ce2df60d Cleanups so that Bison-generated parsers have less lint.
* data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
Prepend /*ARGSUSED*/, for lint's sake.

ba0fe3c710 * data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at

already defined it.
2005-10-13 06:23:54 +00:00
Paul Eggert
4d7aa45e75 * data/c.m4 (b4_c_function_def): Look at __STDC_VERSION__ as well
as __STDC__, as IBM cc defines the former but not the latter.
* data/yacc.c (YYMODERN_C): New macro, which also looks at

__STDC__ and __cplusplus.
2005-10-11 05:36:04 +00:00

2f4f028d8b Undo the parts of the unlocked-I/O change that substituted
putc or puts for printf.  This might hurt performance a bit,
but some people prefer the printf style.
* data/c.m4 (yysymprint): Prefer printf to puts and putc.
* data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.

fb9c0b3360 Use unlocked I/O for a minor performance improvement on hosts like
GNU/Linux and Solaris that support unlocked I/O.  The basic idea
is to use the gnlib unlocked-io module, and to prefer putc and
puts to printf when either will work (since the latter doesn't
come in an unlocked flavor).
* bootstrap (gnulib_modules): Add unlocked-io.
* data/c.m4 (yysymprint): Prefer puts and putc to printf.
* data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.
Prefer them to YYFPRINTF and YYDPRINTF if either will do,
and similarly for puts and putc and printf.
* data/yacc.c: Likewise.
* lib/bitset.c (bitset_print): Likewise.
* lib/bitset.h [USE_UNLOCKED_IO]: Include unlocked-io.h.
* lib/bitsetv.c (bitsetv_dump, debug-bitsetv): Prefer putc and puts
to printf.

d4fb5e3cb9 * data/c.m4 (b4_error_verbose_if): New.
* data/lalr1.cc: Use it.
(YYERROR_VERBOSE_IF): Remove.
(yyn_, yylen_, yystate_, yynerrs_, yyerrstatus_): Remove as
parser members, replaced by...
(yyn, yylen, yystate, yynerss, yyerrstatus): these parser::parse
local variables.
(yysyntax_error_): Takes the state number as argument.
(yyreduce_print_): Use the argument yyrule, not the former
attribute yyn_.
2005-09-29 06:50:57 +00:00
Akim Demaille
cf147260d2 * data/c.m4 (b4_token_enums): New.
(b4_token_defines): Rename as...
(b4_token_enums_defines): this.
(b4_token_defines): New, output only the #defines.
* data/yacc.c, data/glr.c: Adjust.
* data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines.

Paul Eggert
040984073a * NEWS: Version 2.0b.
* data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
the user's name space.  All uses changed to __attribute__
((__unused__)).
(yyFail, yyMemoryExhausted, yyreportAmbiguity):
Add __attribute__ ((__noreturn__)).

* etc/clcommit: Remove.  We weren't using it, and it failed
"make maintainer-distcheck".

Restore old updating code, even though we don't use it, so
that we're the same as coreutils.

Indent calls to "error" to pacify "make maintainer-distcheck",
when the calls are not intended to be translated.

30757c8c93 Add i18n support to the GLR skeleton. Partially fix the C++
skeleton; a C++ expert needs to finish this.  Remove debugging
msgids; there's little point to having them translated, since they
can be understood only by someone who can read the
(English-language) source code.

Generate runtime-po/bison-runtime.pot automatically, so that we
don't have to worry about garbage getting in that file.  We'll
make sure after the next official release that old msgids don't
get lost.  See
<http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.

* runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
Now auto-generated.
* PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
Fix typos in explanations of the runtime file.
* bootstrap: Change gettext keyword from YYI18N to YY_.
Use standard Makefile.in.in in runtime-po, since we'll arrange
for backward-compatible bison-runtime.po files in a different way.
* data/glr.c (YY_): New macro, from yacc.c.
(yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
Translate messages intended for users.
(yyreportSyntaxError): Change "virtual memory" to "memory" to match
the wording in the other skeletons.  We don't know that the memory
is virtual.
* data/lalr1.cc (YY_): Renamed from _.  All uses changed.
Use same method that yacc.c uses.
Don't translate debugging messages.
(yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
it doesn't work (yet), and requires C++ expertise to fix.
* data/yacc.c (YY_): Renamed from YY18N.  All uses changed.
Move defn to a more logical place, to be consistent with other
skeletons.
Don't translate debugging messages.
Don't assume line numbers fit in unsigned int; use unsigned long fmts.
* doc/bison.texinfo: Mention <libintl.h>.  Change glibc cross reference
to gettext cross reference.  Add indexing terms.  Mention YYENABLE_NLS.
* runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
