(getargs): Use it to convert DOSish file names.
* src/files.c (base_name): Rename as full_base_name to avoid
clashes with `base_name ()'.
(filename_split): New.
(compute_base_names): N-th rewrite, using filename_split.
New, stolen from the Fileutils 4.1.
* lib/Makefile.am (libbison_a_SOURCES): Adjust.
* configure.in: Check for the presence of memrchr, and of its
prototype.
* src/Makefile.am: Add parse-skel.c and scan-skel.c to BUILT_SOURCES, to ensure they are generated first.
* src/parse-skel.y: Use YYERROR_VERBOSE instead of %error-verbose to allow bootstrapping with bison 1.30x.
convention is to fetch on entry.
* tests/torture.at (GNU Cim Grammar): Reintroduce their weird
'switch' without a following semicolon.
* tests/regression.at (braces parsing): New.
The ISO C++ standard is extremely clear about it: stderr is
considered a macro, not a regular symbol (see table 94 `Header
<cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
Therefore std:: does not apply to it. It still does with fprintf.
Also, s/cstdio.h/cstdio/.
pure parser and scanner.
* src/parse-skel.y: Request a pure parser, locations, and prefix
renaming.
(%union): Having several members with the same type does not help
type mismatches, simplify.
(YYPRINT, yyprint): New.
(yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
(skel_error): this.
Handle locations.
* src/scan-skel.l: Adjust to these changes.
* src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
(LOCATION_PRINT, skel_control_t): New.
Throw away MS-DOS crap: we don't need getpid.
* configure.in: We don't need strndup. It was even causing
problems: because Flex includes the headers *before* us,
_GNU_SOURCE is not defined by config.h, and therefore strndup was
not visible.
* lib/xstrndup.c: New.
* src/scan-skel.l: Use it.
Be sure to initialize yylval.muscle member when scanning a MUSCLE.
* src/parse-skel.y: Use %directives instead of #defines.
* src/output.c (output_parser, output_master_parser): Remove, dead
code.
* src/output.h (get_lines_number, actions_output, guards_output)
(token_definitions_output): Prototype them.
* src/parse-skel.y: Add the license notice.
Include output.h and skeleton.h.
(process_skeleton): Returns void, and takes a single parameter.
* src/scan-skel.l: Add the license notice.
Include skeleton.h.
Don't use %option yylineno: it seems that then Flex imagines
REJECT has been used, and therefore it won't reallocate its
buffers (which makes no other sense to me than a bug). It results
in warnings for `unused: yy_flex_realloc'.
to guess if the generated parsers should have '.tab' in their
* src/Makefile.am (bison_SOURCES): Add scan-skel.l and
(MUSCLE_INSERT_PREFIX): ...to there.
* src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
(MUSCLE_INSERT_PREFIX): Move from here...
* src/bison.hairy: Add a section directive. Put braces around muscle
names. This parser skeleton is still broken, but Bison should not
choke on a bad muscle 'syntax'.
* src/bison.simple: Add a section directive. Put braces around muscle
names.
* src/files.h (strsuffix, stringappend): Add declarations.
(tab_extension): Add declaration.
(short_base_name): Add declaration.
* src/files.c (strsuffix, stringappend): No longer static. These
functions are used in the skeleton parser.
(tab_extension): New.
(compute_base_names): Use the computations done in this function
to guess if the generated parsers should have '.tab' in their
names.
(short_base_name): No longer static.
* src/output.c (output_skeleton): New.
(output): Disable call to output_master_parser, and give a try to
a new skeleton handling system.
(guards_output, actions_output): No longer static.
(token_definitions_output, get_lines_number): No longer static.
* configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
* src/Makefile.am (bison_SOURCES): Add scan-skel.l and
parse-skel.y.
* src/parse-skel.y: New file.
* src/scan-skel.l: New file.
* src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
Adjust all dependencies.
* tests/headers.at (export YYLTYPE): Strengthen this test: use
%name-prefix.
Renaming yylval but not yylloc is not consistent. Now we do.
* src/bison.simple: Prefix yylloc if used.
* doc/bison.texinfo (Decl Summary): Document that.
on command. Now possible via `symbols'. Fixes a memory leak.
* src/output.c (token_definitions_output): New.
(output_parser, header_output): Use it.
* src/reader.c (symbols_save): Remove.
* src/reader.c (readgram): Be sure to attach mid-rule actions to
the empty-rule associated to the dummy symbol, not to the host
rule.
* tests/actions.at (Mid-rule actions): New.
* src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
since it allocates it for each state, although only one is needed.
(allocate_storage): Do it here.
