skeletons, and use this for %code qualifier complaints.
* data/bison.m4 (b4_error_at): New, invoked by...
(b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
@fatal_at(...@) directives.
(b4_check_percent_code_qualifiers): Rewrite to expect locations for
qualifiers in b4_used_percent_code_qualifiers and to use
b4_complain_at.
* src/location.c, src/location.h (boundary_set_from_string): New global
function.
* src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
function.
* src/parse-gram.y (grammar_declaration): Add locations for qualifiers
to b4_used_percent_code_qualifiers.
* src/scan-skel.l (fail_for_at_directive_too_few_args): New static
function.
(AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
(lineno): Rename to...
(out_lineno): ... this so I don't misunderstand it again.
(SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
here; these newlines are in the input but not the output file.
(SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
(at_directive_perform): ... this new static function, and add handling
of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
directives.
* tests/input.at (Reject bad %code qualifiers): Update test output with
locations and extend.
* tests/output.at (Output file name: [, Output file name: ]): Remove
bogus comment about these tests failing.
`bison ', use m4_index instead of m4_substr since chopping up a string
containing M4-special characters causes problems here.
Fix a couple of bugs related to special characters in user-specified
file names, and make it easier for skeletons to compute output file
names with the same file name prefix as Bison-computed output file
names.
* data/glr.cc, data/push.c, data/yacc.c: In @output, use
b4_parser_file_name and b4_spec_defines_file instead of
@output_parser_name@ and @output_header_name@, which are now redundant.
* data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
b4_parser_file_name, b4_spec_defines_file, and the new
@basename(FILENAME@) instead of @output_parser_name@ and
@output_header_name@, which inappropriately escaped the file names as
C string literals.
* src/files.c (all_but_ext): Remove static qualifier.
(compute_output_file_names): Move `free (all_but_ext)' to...
(output_file_names_free): ... here since all_but_ext is needed later.
* src/files.h (all_but_ext): Extern.
* src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
exactly what MUSCLE_INSERT_STRING used to do.
(MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
characters are escaped properly.
* src/output.c (prepare): Define muscle file_name_all_but_ext as
all_but_ext.
For pkgdatadir muscle, maintain previous functionality by using
MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
is that b4_pkgdatadir is used inside m4_include in the skeletons, so
digraphs would never be expanded. Hopefully no one has M4-special
characters in his Bison installation path.
* src/scan-skel.l: Don't parse @output_header_name@ and
@output_parser_name@ anymore since they're now redundant.
In @output, use decode_at_digraphs.
Parse a new @basename command that invokes last_component.
(decode_at_digraphs): New.
(BASE_QPUTS): Remove unused.
* tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
(Output file name): New tests.
conflict with other output files.
* data/glr.c: Don't generate the header file here when glr.cc does.
* src/files.c (file_names, file_names_count): New static globals.
(compute_output_file_names): Invoke output_file_name_check for files
not generated by the skeletons and remove existing checks.
(output_file_name_check): New function that warns about conflicting
output file names.
(output_file_names_free): Free file_names.
* src/files.h (output_file_name_check): Declare.
* src/scan-skel.l: Invoke output_file_name_check for files generated by
the skeletons.
* tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
(Conflicting output files): New tests.
%file-prefix, %name-prefix, and %output. Discussed at
<http://lists.gnu.org/archive/html/help-bison/2006-09/msg00001.html>.
* NEWS (2.3a+): Mention.
* doc/bison.texinfo (Decl Summary, Bison Symbols): Add entry for new
form of %defines, and remove `=' from entries for %file-prefix,
%name-prefix, and %output.
* src/parse-gram.y (prologue_declaration): Implement.
* tests/calc.at (Simple LALR Calculator, Simple GLR Calculator, Simple
LALR1 C++ Calculator, Simple GLR C++ Calculator): Remove the `=' from
all but one occurrence of %name-prefix.
* tests/headers.at (export YYLTYPE): Remove the `=' from %name-prefix.
* tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Likewise.
* tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
occurrence of each of %file-prefix and %output. Add check for %defines
with argument.
* tests/reduce.at (Useless Terminals, Useless Nonterminals,
Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
Remove the `=' from %output.
header file names.
* tests/output.at (AT_CHECK_OUTPUT): Support subdirectorioes, and
additional checks.
Use this to exercise C++ outputs in subdirs.
Reported by Oleg Smolsky.
* tests/output.at (AT_CHECK_OUTPUT): Likewise.
* tests/headers.at (AT_TEST_CPP_GUARD_H): Ditto.
* tests/semantic.at (Parsing Guards): Similarly.
* src/reader.at (readgram): Complain if the last rule is not ended
with a semi-colon.
* tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
now the tests are run in private dirs, therefore AC_CLEANUP and
family can be simplified to 0-ary.
* tests/atlocal.in: Now that we run `elsewhere' than in tests/,
use abs. path to find config.h.
* tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's
stderr, there can be way too much random noise.
Instead pass -Werror to GCC and rely on the exit status.
Reported by Wolfram Wagner.
* src/options.c (longopts): Support `--output' and `%output'.
(usage): Adjust.
* src/lex.h (tok_setopt): Remove, replaced with...
(tok_intopt, tok_stropt): these new guys.
* src/lex.c (getopt.h): Not needed.
(token_buffer, unlexed_token_buffer): Not const.
(percent_table): Promote `-' over `_' in directive names.
Active `%name-prefix', `file-prefix', and `output'.
(parse_percent_token): Accept possible arguments to directives.
Promote `-' over `_' in directive names.
