1 2006-07-04 Gary V. Vaughan <gary@gnu.org>
3 * ltdl/m4/m4-getopt.m4 (M4_GETOPT): Update to take into account
4 changes to gnulib getopt.m4 since last build.
5 * Makefile.am (src_m4_SOURCES): Only compile shipped getopt module
6 if the system getopt fails M4_GETOPT tests.
8 2006-06-22 Eric Blake <ebb9@byu.net>
10 * Makefile.am (EXTRA_DIST): Distribute gnulib-cache.m4.
11 Reported by Bruno Haible.
13 2006-06-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
15 * m4/module.c (m4__module_exit): Avoid ltdl memory leak.
17 2006-06-19 Eric Blake <ebb9@byu.net>
21 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
23 * Makefile.am (src_m4_DEPENDENCIES): Make dependency explicit.
24 (clean-local): Split into and depend upon...
25 (clean-local-tests, clean-local-src): ...these two. The latter
26 removes the libtool object directory below `src', to work around
27 a buglet in Automake, failing to list it.
28 (EXTRA_DIST): Distribute modules/perl.c.
30 2006-06-19 Eric Blake <ebb9@byu.net>
32 * Makefile.am ($(srcdir)/doc/m4.1): No need to list $(srcdir) in
33 right side of dependency; VPATH does that.
34 (stamp-vcl): Update to use libtool's algorithm.
35 (EXTRA_DIST): Distribute stamp-vcl.
36 Reported by Ralf Wildenhues.
37 (TESTSUITE): Revert earlier change that used absolute path, as
38 that broke 'make dist' in VPATH. Stick with $(srcdir) instead.
39 (EXTRA_DIST): Revert earlier change of $(TESTSUITE).
40 (TESTS_ENVIRONMENT) [USE_GMP]: Revert earlier addition, since
41 atlocal takes care of it instead.
42 (check-local, installcheck-local, clean-local): Inline absolute
43 path to testsuite here, rather than relative path to testsuite
46 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
48 * m4/m4private.h (DELETE): Cast away const here...
49 * src/stackovf.c (stackovf_exit): ...to avoid cast-as-lvalue here.
50 * src/freeze.c (reload_frozen_state): Avoid uninitialized
53 2006-06-19 Eric Blake <ebb9@byu.net>
55 * Makefile.am (doc/m4.1): Build in $(srcdir), to match where
56 .info pages are built.
57 Reported by Ralf Wildenhues.
58 (EXTRA_DIST): Inline definition of testsuite, so that make dist
61 2006-06-16 Eric Blake <ebb9@byu.net>
63 Follow recommendations from autoconf manual for autotest.
64 * Makefile.am (TESTSUITE): Factor the $(srcdir) out of uses, and
65 turn it into an absolute path until autotest provides an option
66 that allows us to avoid changing directories. Properly quote
68 (TESTS_ENVIRONMENT) [USE_GMP]: Inform testsuite about GMP.
69 (check-recursive): Delete unused target.
70 ($(TESTSUITE)): Atomically update testsuite.
71 (CD_TESTDIR): Simplify.
72 (m4__cd): Delete unused macro.
73 (check-local): Let TESTSUITEFLAGS influence the run.
74 (installcheck-local): Let TESTSUITEFLAGS override
75 AUTOTEST_PATH. Add dependencies.
76 (clean-local): Clean up.
77 (DISTCLEANFILES, MAINTAINERCLEANFILES): Add directory location.
78 * README: Document how to use the testsuite.

92 * ltdl/m4/debug.m4 (M4_CHECK_DEBUGGING): Likewise.
93 * configure.ac: Likewise.
94 (M4_DEFAULT_PRELOAD): Use as a macro, not shell variable.
95 * Makefile.am (src_m4_CPPFLAGS): Use STACKOVF as a makefile
97 * ltdl/m4/m4-gnulib.m4: Delete, no longer needed.
99 Reduce compiler warnings. Inside GMP, mpq_t is an array type, so
100 const mpq_t is not assignable from plain mpq_t. Avoid
101 type-punning warnings caused trying to mix these types.
102 * modules/mpeval.c (numb_ior, numb_eor, numb_and, numb_lshift),
103 (numb_rshift, numb_divide, numb_modulo): Remove const qualifier.
104 * modules/evalparse.c (or_term, xor_term, and_term, shift_term),

114 * Makefile.am (modules_mpeval_la_LIBADD): Readd $(LIBADD_GMP).
116 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
117 Eric Blake <ebb9@byu.net>
119 Allow `make dist' to work again.
120 * Makefile.am (EXTRA_DIST): doc/helptoman.pl is gone.
121 (MAINTAINERCLEANFILES): Avoid redundant mention of dist_man_MANS.
122 (cvs-dist): Fix typo.
123 * NEWS: Match current version number.
125 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
127 * Makefile.am (AM_CPPFLAGS): Add $(LTDLINCL), so the right
130 * bootstrap: Do not run libtoolize manually, this is done
131 correctly by autoreconf. Invoke autoreconf with --no-recursive
132 to avoid unnecessary rerunning of autotools for libltdl.
134 2006-06-13 Eric Blake <ebb9@byu.net>
138 2006-06-12 Eric Blake <ebb9@byu.net>
140 * m4/output.c [HAVE_MKTEMP]: Gnulib provides mkstemp, so don't
142 * src/m4.h: Don't declare mktemp.
143 * m4/input.c (m4__next_token): Avoid bzero.
144 * configure.ac (AC_CHECK_FUNCS): Remove obsolete checks.
145 * Makefile.am (doc/m4.1): Depend on installed help2man, rather
146 than distributing outdated helptoman.pl.
147 * doc/helptoman.pl: Delete.
149 2006-06-10 Eric Blake <ebb9@byu.net>
151 * README (Patches): Document the current dependence on CVS

154 * configure.ac: Use consistent quoting throughout.
155 (AC_PREREQ): Bump to 2.59d.
156 (AC_INIT): Package name begins with uppercase.
157 (AC_ARG_WITH): Use AS_HELP_STRING.
158 (AM_INIT_AUTOMAKE): Enable gnits mode.
159 (AC_ISC_POSIX, AM_PROG_CC_STDC, AC_PROG_INSTALL, AC_PROG_MAKE_SET),
160 (AC_PROG_AWK, AM_C_PROTOTYPES, AC_C_CONST, AC_HEADER_STDC),
161 (AC_CHECK_HEADERS, AC_FUNC_ALLOCA, AC_FUNC_VPRINTF): Remove checks
162 done by gnulib or automake, or which autoconf has declared
164 * m4/m4private.h (Includes): Assume C89 or better, and use errno
166 * m4/output.c (Includes): Likewise.

173 about cygwin. Document bootstrapping dependency.
174 * AUTHORS: Update from branch-1_4.
175 * THANKS: Likewise. Change encoding to UTF-8.
176 * BACKLOG: Delete. This file is too old and unmaintained to be
178 * ChangeLog: Change encoding to UTF-8.
180 Avoid compiler warnings.
181 * m4/macro.c (trace_format): Don't mark this as a printf format,
182 since we don't accept the same set of modifiers as printf. It
183 would be nice if gcc let us specify a custom format archetype.
184 * src/main.c (main): Cast away const.
186 2006-06-10 Andreas Schwab <schwab@suse.de> (tiny change)
187 Eric Blake <ebb9@byu.net>
189 * modules/time.c (ctime): Pass correctly typed variable to
192 (localtime): Likewise.
193 (strftime): Likewise.
194 * m4/utility.c (m4_numeric_arg): For now, document arbitrary
195 limit inherent in this interface.
197 2006-05-08 Bruno Haible <bruno@clisp.org> (tiny change)
199 * modules/m4.c (WEXITSTATUS): Provide fallback definition.
200 (sysval): Use WEXITSTATUS.
201 * modules/gnu.c (esyscmd): Set sysval to 0xffff, to accomodate both
202 big-endian and little-endian wait status definitions.
204 2006-05-06 Eric Blake <ebb9@byu.net>
206 * configure.ac (LT_CONFIG_LTDL_DIR): Inform libtool which

223 * bootstrap: Update usage of gnulib-tool.
225 2006-05-04 Eric Blake <ebb9@byu.net>
227 * Makefile.am (doc/m4.1): Use EXEEXT on built binary.
230 2005-12-05 Gary V. Vaughan <gary@gnu.org>
232 * bootstrap (func_update_po): Synch with CVS GNU tar. wget 1.9.x
233 and 1.10.x support --cache=off, so $WGETFLAGS are not necessary.
234 Reported by Eric Blake <ebb9@byu.net>
236 2005-12-04 Gary V. Vaughan <gary@gnu.org>
238 * bootstrap (func_update_po): Test and set $WGETFLAGS to disable
239 http caching as -C is no longer supported by wget 1.10.x.
240 Reported by Eric Blake <ebb9@byu.net>
242 2005-10-20 Gary V. Vaughan <gary@gnu.org>
244 * m4/module.c (caller_id): To match libtool-2.0 interface, changed
246 (iface_id): ...an lt_dlinterface_id type.
247 (m4__module_find): New abstraction for lt_dlhandle_fetch. Use
248 throughout, instead of calling obsolete lt_dlhandle_find directly.
249 (m4__module_next): Use multiloader-safe lt_dlhandle_iterate. Use
250 throughout, instead of calling obsolete lt_dlhandle_next.
251 * m4/m4private.h (m4__module_find): Declare it.
252 * m4/builtin.c (m4_builtin_find_by_name, m4_builtin_find_by_func):
253 Use m4__module_next instead of obsolete lt_dlhandle_next.
255 2005-10-20 Gary V. Vaughan <gary@gnu.org>
257 * bootstrap (func_update_po): Update pofiles directly from the
259 * po/LINGUAS, po/cs.po, po/de.po, po/el.po, po/fr.po, po/it.po,
260 po/ja.po, po/nl.po, po/pl.po, po/ru.po, po/sv.po: No need to store
261 these files under source control anymore.
262 Suggested by Eric Blake <ebb9@byu.net>
264 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
266 * ltdl/m4/m4-gnulib.m4: Update FSF contact address. Somehow this
267 file escaped the address updates on 2005-05-01.
269 2005-07-07 Gary V. Vaughan <gary@gnu.org>
271 * bootstrap: Allow user overriding of gnulib-tool location, and
272 correctly determine module source directories whether gnulib-tool
273 is given as a relative or absolute path, or is found by searching
275 Reported by Eric Blake <ebb9@byu.net>
277 2005-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

280 and $RM are defined for various versions of
281 AC_LIBTOOL_COMPILER_OPTION.
283 * bootstrap (AUTORECONF): New variable to allow user overriding of
286 2005-07-07 Gary V. Vaughan <gary@gnu.org>
288 * doc/m4.texinfo (History): Add better notes on the ancestory of
289 GNU m4, and other historical interest.
291 2005-05-08 Gary V. Vaughan <gary@gnu.org>
293 * m4/symtab.c (m4_symbol_rename): New function that performs a low
295 * m4/m4module.h (m4_symbol_rename): Declare it as part of the API.
296 * modules/gnu.c (regsub): Factored out of m4_epatsubst_do...
297 (m4_patsubst_do, m4_renamesyms_do): ...wrappers that use
299 (erenamesyms, renamesyms): ...builtins that use these to implement
300 macro renaming by regular expression.
301 * doc/m4.texinfo (Erenamesyms and Renamesyms): Document them.
302 * tests/generate.awk: Allow some forbidden `m4_' prefixed symbols
303 to stop the new generated tests from choking.
305 2005-05-07 Gary V. Vaughan <gary@gnu.org>
307 Since most of the build is handled from a single Makefile.am now,
308 we can teach make about the dependencies between the m4 binary and
309 the preopened modules it is built against:
311 * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
313 * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
314 of the preopened modules have changed.
316 2005-05-07 Gary V. Vaughan <gary@gnu.org>
318 * configure.ac (gl_MODULES): Add mkstemp for machines that don't
319 have a native implementation.
321 2005-05-06 Gary V. Vaughan <gary@gnu.org>
323 * src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are
324 handled already by gnu/exit.h.
326 * configure.ac (gl_MODULES): Add assert to support a
327 --disable-assert configure time option for NDEBUG setting.
329 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.
330 * bootstrap (src_modules): Add version-etc-fsf.
331 * src/main.c (version_etc_copyright): Removed.
333 * ltdl/m4/m4-getopt.m4 (m4_GETOPT): Synch with gnulib/getopt.m4.
335 2005-05-04 Gary V. Vaughan <gary@gnu.org>
337 * src/m4.h (__CYGWIN__, WIN32): Canonicalise Windows and Cygwin
339 * src/freeze.c (produce_frozen_state): Use \n line-endings even
340 on Windows, so that the frozen file reader will work.
341 Reported by Josef T. Burger <bolo@bolo.com>
343 2005-05-04 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
345 Forward port of a patch that allowed m4-1.4.2 to compile on
348 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
350 * src/m4.h: And include them as appropriate.
351 * src/main.c, src/stackovf.h: Don't include signal.h literally;
352 m4.h will include the correct file.
354 2005-05-04 Gary V. Vaughan <gary@gnu.org>
356 * m4/m4private.h: Make errno visible for the sources patched
359 2005-05-04 Paul Eggert <eggert@twinsun.com>
361 * src/main.c (print_program_name_CB): Preserve errno, since
362 M4ERROR relies on this.
363 * modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
364 * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
365 * m4/path.c (m4_path_search): Don't let "free" trash errno when
368 * m4/output.c (m4_insert_file): Don't assume errno has a valid
369 value simply because fread returns zero. This fixes a
370 portability bug reported by Marion Hakanson in
371 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
373 2005-05-04 Santiago Vila <sanvila@debian.org>
375 * tests/stackovf.test: Use tempfile if available.

379 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=92629
380 * m4/output.c (m4_insert_file): Do not mix buffered and
381 unbuffered I/O, as this breaks on the Hurd.
383 2005-05-04 Gary V. Vaughan <gary@gnu.org>
385 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
386 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
387 and libtoolize does a better job of ltdl importing now too, so
388 take advantage of that while updating the tree:
390 * acm4, config: Moved from here...
391 * ltdl/m4, ltdl/config: ...to here.
392 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
393 src/Makefile.am, tests/Makefile.am: Removed...
394 * Makefile.am: ...and migrated to here, with adjustments to
395 compensate for relative path differences.
396 * commit: Adjust relative paths.
397 * configure.ac: Adjust relative paths.
398 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
400 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
401 the meanwhile, CVS HEAD libtool is needed.
402 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
403 stricly new enough, we also need a patch.
404 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
405 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
406 (gl_MODULES): Don't list getopt and version-etc, as they don't
408 * bootstrap: After running gnulib-tool to import the listed
409 modules, fetch getopt and version-etc into src manually.
410 (ltdldir): Change to ltdl.
411 * src/main.c: Adjust for changes in version-etc API.
412 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
413 but works when the getopt module isn't to be included in the lib.
414 * README: Add note about patching autoconf and automake to

419 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=84416
420 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
421 empty file rather than to a nonexistent file. This closes a
422 common security hole.
423 * modules/m4.c (m4_maketemp): Implement the above, by using
424 mkstemp rather than mktemp.

468 * m4/m4.c (m4_context_field_table, m4_context_opt_bit_table):
469 Protect definitions from macro expansion under -DNDEBUG by
470 parenthesising the expanded function names.
471 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
472 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
473 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
474 (m4_is_syntax_macro_escaped): Similarly protect function
475 definitions from macro expansion under -DNDEBUG by #undefing the
476 matching macro names before each definition. Also, move all the
477 function definitions to the end of the file so that any
478 invocations in the rest of the file pick up the fast macro
480 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)
481 (m4_set_debug_file, m4_set_trace_messages)

483 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
484 (m4_set_max_debug_arg_length_opt): New fast macro versions of the
485 option setter functions.

489 * src/main.c: Include gnulib files from the correct directory.
491 * gnulib/*: Don't store any of the gnulib files in arch, as they
492 generate spurious changes.
493 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
494 gnulib macros now share our macro directory.
495 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
496 * bootstrap: Call gnulib-tool to import from the gnulib tree.
497 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
498 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
499 the gettext macros from autopoint that overwrite the gnulib-tool
500 imported versions. Import sources and Makefile.am into the `gnu'
501 directory. Changed all callers.
502 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
503 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
504 for imported modules.
505 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
506 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
507 hardcoding the gnulib macros they wrap.
509 2004-07-15 Gary V. Vaughan <gary@gnu.org>
511 Latest CVS libtool can preload modules in libraries, including
512 its own module loaders! Tweak m4 so that it doesn't try to treat
513 libltdl's module loaders as m4 modules when freezing and on exit:
515 * gnulib/acm4/*.m4: Don't store these files in arch since they
516 generate spurious changes.
517 * bootstrap: Simplify initial libtoolize call, since CVS
518 libtoolize is smarter these days.
519 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
521 * m4/module.h (m4__module_exit): Missing declaration.
522 * m4/m4private.h (m4__module_next): New function declaration.
523 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
524 encapsulation. Changed all callers.
525 (m4__module_interface): New function to verify m4 loadable module
527 (m4__module_init): Register the interface validator.
528 (m4__module_exit): Only close my own modules.
529 * modules/m4.c (unistd.h): Provide missing declaration.
530 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
531 (m4_expand_ranges): More missing declarations.
532 * modules/modtest.c (export_test): Ditto.
533 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
534 * src/main.c (main): Bump copyright year.
535 * tests/modules.at: Fix sed syntax error.
538 2004-06-17 Gary V. Vaughan <gary@gnu.org>
540 Tweaking to enable compilation with latest CVS libtool and
541 libltdl. We can't just dump the library files directly into the
542 m4 directory anymore now that libltdl is built from pieces itself:
544 * bootstrap: Rewritten to use latest libtoolize sanely, and to
545 set up libltdl subdirectory.
546 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
547 gnulib subdirectory's config.
548 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
549 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
551 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
552 configure.ac, so use AC_WITH_LTDL instead.
553 * Makefile.am (SUBDIRS): Add libltdl.
554 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
556 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
557 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
558 (libm4_la_LIBADD): Add LIBLTDL.
559 * m4/ltdl.c, m4/ltdl.h: Removed.
560 * m4/m4module.h: Include canonical ltdl.h.
563 2004-06-14 Gary V. Vaughan <gary@gnu.org>
565 * gnulib/import: Now updates makefile fragments, and configure.ac.
566 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
567 * gnulib/m4/Makefile.am: include it.
568 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
569 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
570 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
571 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
572 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
573 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,
574 gnulib/acm4/lib-ld.m4, gnulib/acm4/lib-prefix.m4,
575 gnulib/acm4/error.m4, gnulib/acm4/po.m4, gnulib/acm4/regex.m4,
576 gnulib/acm4/stdbool.m4, gnulib/acm4/stdint_h.m4,
577 gnulib/acm4/uintmax_t.m4, gnulib/acm4/ulonglong.m4,
578 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
579 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
580 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
582 * gnulib/m4/getopt_int.h: New source file from latest gnulib
584 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
585 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,
586 gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
587 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
588 Updated source files from latest gnulib.
590 2004-02-29 Gary V. Vaughan <gary@gnu.org>
592 * config/mailnotify: New file for mailing commit notifications,
593 imported from cvs-utils.
594 * commit: Updated from cvs-utils and tweaked for m4.
596 2003-12-01 Gary V. Vaughan <gary@gnu.org>
598 * config/mkstamp: Updated from CVS libtool.
599 * configure.ac: Generate a gnu coding standards compliant version
600 number, and use it for the banner.
601 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
602 mhen the TIMESTAMP changes in ChangeLog, but the file modification
603 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
604 contain the previous version number.
605 * src/main.c: Make --version output conform to the GNU standard.
607 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
608 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
609 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
610 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
611 time_la_SOURCES): ...so that these are defaulted correctly, and
612 can be removed from this file.
613 (AM_LDFLAGS): Add -module...
614 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
615 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
616 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
617 the individual settings can be removed.
618 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
619 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
620 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
621 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
622 time_la_LIBADD): ...so that these are picked up as a deplib of
623 libm4 and don't need to be set explicitly.
625 2003-11-18 Gary V. Vaughan <gary@gnu.org>
627 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
628 from the standard build. It is too fragile.
630 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
631 CVS libtool after merging m4 changes across to libtool.
633 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
634 * m4/path.c (search_path_add): Ditto.
636 2003-11-13 Gary V. Vaughan <gary@gnu.org>
638 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
639 libtool tags we don't use in configure. This reduces the size
640 of the script from over 1Mb to under 700Kb.
642 2003-11-13 Gary V. Vaughan <gary@gnu.org>
644 The import script was not written properly, and the last gnulib
645 import was incomplete. Fixed that problem, and reimport our
646 gnulib dependencies, which picks up the address calculation
647 overflow checks described by Paul below. Also tweak the clients
648 of the gnulib xalloc module not to use deprecated macros:
650 * gnulib/import: Recurse through module dependencies rather than
651 naively descending only one level.
652 * configure.ac: Add calls to gnulib's strnlen and extension module
654 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
656 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
657 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
658 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
659 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
661 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
662 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
663 place of `xcalloc (1, S)'.
664 * m4/m4.c (m4_create): Likewise.
665 * m4/m4private.h (m4_symbol_value_create): Likewise.
666 * m4/symtab.c (symtab_fetch): Likewise.
667 * m4/syntax.c (m4_syntax_create): Likewise.
668 * src/freeze.c (reload_frozen_state): Likewise.
669 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
671 * m4/symtab.c (m4_symtab_create): Likewise.
673 2003-11-13 Gary V. Vaughan <gary@gnu.org>
675 * tests/module.at: Comment typo.
677 2003-10-10 Gary V. Vaughan <gary@gnu.org>
679 * tests/modules.at (modules: importing): Apply some lateral
680 thinking, and use AT_CHECK to compare the output of a sed pass
681 over stderr against the canonical strerror string.
683 * tests/modules.at (modules: importing): Edit the generated stderr
684 output to canonicalize strerror output, before a comparison.
686 2003-10-10 Gary V. Vaughan <gary@gnu.org>
688 Tru64UNIX perl is sloppy with namespace pollution. This patch is
689 careful not to trip over the mess:
691 * modules/perl.c: Some builds of perl install headers that contain
692 `#define try __builtin_try'. Be sure to undefine that macro
693 before `m4/hash.h' gets included, which uses the `try' symbol.
694 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
695 `false' before including `stdbool.h'.
696 (DELETE): This symbol is not in m4's namespace, and is in any
697 case only used internally...
698 * m4/m4private.h (DELETE): ...so move it to here.
699 Reported by Martin MOKREJS <mmokrejs@natur.cuni.cz>
701 2003-10-08 Paul Eggert <eggert@twinsun.com>
703 Don't use XMALLOC and XCALLOC. Once we install the
704 corresponding patch into gnulib, this will fix some
705 address-calculation overflow bugs on hosts where calloc (A, B)
706 returns garbage when A*B overflows.
708 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
709 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
710 xmalloc, XCALLOC with xcalloc.
711 * m4/m4.c (m4_create): Likewise.
712 * m4/m4private.h (m4_symbol_value_create): Likewise.
713 * m4/output.c (m4_output_init): Likewise.
714 * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise.
715 * m4/syntax.c (remove_syntax_attribute): Likewise.
716 * src/freeze.c (reload_frozen_state): Likewise.
717 * src/main.c (main): Likewise.
719 2003-10-07 Gary V. Vaughan <gary@gnu.org>
721 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
722 gnulib/acm4 directories for aclocal m4 macros.
723 * gnulib/Makefile.am (EXTRA_DIST): Removed.
724 (MAINTAINERCLEANFILES): Add Makefile.in.
725 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
727 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
728 * gnulib/import: New file. Temporary script for updating gnulib
729 imported files, until gnulib-tool is working.
730 * gnulib/config/codeset.m4, gnulib/config/error.m4,
731 gnulib/config/exitfail.m4, gnulib/config/extensions.m4,

768 gnulib/acm4/xstrndup.m4: Reimported from CVS gnulib with
769 gnulib/import script.
770 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/error.c,
771 gnulib/m4/error.h, gnulib/m4/exitfail.c, gnulib/m4/free.c,

774 gnulib/m4/version-etc.c, gnulib/m4/version-etc.h,
775 gnulib/m4/xalloc.h, gnulib/m4/xmalloc.c: Updated from CVS
776 gnulib with gnulib/import script.
777 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
778 guards ready for gnulib-tool to autoupdate on import.
779 * config/debug.m4, config/gmp.m4, config/m4-error.m4,
780 config/m4-gettext.m4, config/m4-obstack.m4, config/m4-regex.m4,
781 config/stackovf.m4: Moved from here...
782 * acm4/debug.m4, acm4/gmp.m4, acm4/m4-error.m4,
783 acm4/m4-gettext.m4, acm4/m4-obstack.m4, acm4/m4-regex.m4,
784 acm4/stackovf.m4: ...to here, to separate aclocal macros from
785 configure time helper scripts.

787 * m4/hash.c, m4/m4.c, m4/macro.c, m4/module.c, m4/output.c,
788 m4/path.c, m4/symtab.c, m4/syntax, m4/system_.h, modules/m4.c,
789 src/main.c, src/stackovf.c: s/xfree/free/g to comply with new
791 * src/main.c (version_etc_copyright): Only output the current
793 (version_etc): Call with new variadic API.
795 2003-09-16 Gary V. Vaughan <gary@gnu.org>
797 * gnulib/m4/version-etc.c, gnulib/m4/version-etc.h: Import
798 version-etc module from CVS gnulib.
799 * po/POTFILES.in: Add gnulib/m4/version-etc.c.
800 * src/Makefile.am: Build it.
801 * src/main.c: Use it.

804 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
805 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
808 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
809 Gary V. Vaughan <gary@gnu.org>
811 * bootstrap: Separate options.
812 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
813 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
815 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
816 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
817 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
818 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
819 $(LTLIBINTL) for gettext support on cygwin.
820 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
821 have $(LTLIBINTL) from the preloaded module la files.
822 * README: Remove the warning about using --disable-nls on Windows
825 2003-09-15 Gary V. Vaughan <gary@gnu.org>
827 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
828 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
831 2003-09-12 Gary V. Vaughan <gary@gnu.org>
833 * doc/STYLE: Document the gnulib header naming conventions, and
835 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
836 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,
837 gnulib/m4/gettext.h, gnulib/m4/obstack.h, gnulib/m4/regex.h
839 * gnulib/m4/Makefile.am: Remove the rules to build these headers.
841 * gnulib/m4/strtol.c, gnulib/config/strtol.m4: Import strtol
842 module from CVS gnulib.
843 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
844 (gl_FUNC_STRTOL): In favour of the module macro.
846 2003-09-12 Gary V. Vaughan <gary@gnu.org>
848 Replace the getopt code with CVS gnulib getopt. The source files
849 detect whether they are in a glibc environment and preprocess away
850 all of the code if there is a system getopt, so we can compile
851 them into the m4 executable unconditionally:
853 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
854 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
855 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
857 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
859 * src/Makefile.am: Adjust.
860 * src/main.c: Always include our shipped getopt.h.
861 * po/POTFILES.in: Use new location of getopt.c.
863 2003-09-12 Gary V. Vaughan <gary@gnu.org>
865 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
866 * config/Makefile.am: Removed. Automake 1.8 distributes the files
867 in this directory automatically.
868 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
870 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
872 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
874 * modules/Makefile.am (pkglibexecdir): Set it here.
875 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
877 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
878 Import regex module from CVS gnulib.
879 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
880 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
881 do extra substitutions for Makefile.
882 * configure.ac: Use it.
883 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
884 from regex_.h if necessary.
885 * m4/system_.h: Include the correct version of regex.h.
886 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
888 * po/POTFILES.in: Use new location of regex.c.
890 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
891 realloc.c: automake distributes these files already.
893 2003-09-12 Gary V. Vaughan <gary@gnu.org>
895 Replace the xstrzdup code by importing the xstrndup module from
896 CVS gnulib, along with its dependencies: strndup and strnlen:
898 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
899 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
901 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
902 gnulib/config/strndup.m4: Ditto wrt strndup.
903 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
905 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
906 However, contrary to gnulib, we install xstrndup.h.
907 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
908 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
909 is an artifact of the old m4 portability layer.
910 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
911 * m4/system_.h: Include xstrndup.h.
912 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
914 2003-09-11 Gary V. Vaughan <gary@gnu.org>
916 Reimport the latest xalloc module from CVS gnulib, and adjust the
917 m4 sources to take advantage of xalloc xfree. Also create a new
918 macro DELETE with the same semantics as the old m4 XFREE macro,
919 and carefully tweak callers:
921 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
923 * m4/utility.c (xfree): Removed. This function is now supplied by
925 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
926 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
927 * m4/symtab.c (m4_symtab_create): Ditto.
928 * m4/system_.h: Removed XFREE redefine.
929 (DELETE): New macro with same functionality as the original m4
930 XFREE macro, but based on xalloc.h now. Changed all callers.
931 * src/main.c (main): Use XMALLOC macro.
932 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
934 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
936 2003-09-10 Gary V. Vaughan <gary@gnu.org>
938 Import the xalloc module from CVS gnulib, along with its
939 dependencies: exitfail, malloc and realloc. We had different
940 semantics for our XFREE and a function xfree() not supplied by
941 gnulib, so also a bit of work to keep everything running
944 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
945 (gl_XALLOC): Use gnulib equivalents.
946 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
947 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
948 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
949 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
951 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
952 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
953 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
955 (pkgincdir): Removed. Use pkgincludedir instead.
956 * m4/m4private.h (XFREE): xfree already checks for NULL.
957 * m4/system_.h: Use xalloc module, and remove macros already
958 supplied by xalloc.h.
959 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
960 moved the old definition from m4/xmalloc.c to here for now.
962 2003-09-09 Gary V. Vaughan <gary@gnu.org>
964 Import the error and progname modules from CVS gnulib. Our old
965 error.c subsumed the functionality of both, so a little adjustment
966 was required to accomodate the split in sources. Also added more
967 wrapper macros to choose between a system installed error.h or our
968 shipped gnulib error module:
970 * m4/error.c, m4/error.h: Removed.
971 * m4/Makefile.am: Adjust.
972 (pkgincdir): Removed. Use pkgincludedir instead.
973 * m4/module.h, src/main.c: Don't include `m4/error.h'.
974 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
976 * gnulib/m4/progname.c: Imported from CVS gnulib.
977 * gnulib/m4/progname.h: Ditto.
978 * src/main.c: Adjust to use progname module.
979 * gnulib/m4/error.c: Imported from CVS gnulib.
980 * gnulib/m4/error_.h: Ditto.
981 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
982 if appropriate, and link a local error.h if the system version is
984 (libgnu_la_SOURCES) Add progname module sources.
985 * gnulib/config/error.m4: Imported from CVS gnulib.
986 * gnulib/config/strerror_r.m4: Ditto.
987 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
988 to have ERROR_H for Makefile substitutions and tell system.h
989 whether the system error.h should be used, or a locally installed
991 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
993 2003-09-09 Gary V. Vaughan <gary@gnu.org>
995 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
996 s/gettext_.h/gettext.h/.
998 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
999 automake have been fixed.
1001 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
1002 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
1003 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
1004 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
1006 2003-09-09 Gary V. Vaughan <gary@gnu.org>
1008 The gnulib obstack module requires the gnulib gettext module for
1009 systems that do not have GNU gettext installed. Because we use
1010 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
1011 that directory incase it clashes with the system gettext.h. This
1012 delta uses gettext_.h and extra rules in the Makefile to make a
1013 link to gettext.h when needed:
1015 * Makefile.am (auxdir): Removed. No longer used.
1016 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
1017 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
1019 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
1020 Makefile based build.
1021 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
1022 of the macros are kept.
1023 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
1024 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
1025 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
1026 distributes these automatically.
1027 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
1028 warning from automake-1.7a.
1029 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
1030 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
1032 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
1033 wrt. m4_FUNC_OBSTACK.
1034 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
1035 wrt. m4_sys_STACKOVF.
1036 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
1037 wrt. _m4_LIB_GMP, m4_LIB_GMP.
1038 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
1039 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
1041 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
1042 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
1043 gettext.h link on deficient systems.
1044 (pkginc_HEADERS): Mention $(GETTEXT_H).
1045 (EXTRA_HEADERS): Mention gettext.h.
1046 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
1047 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
1048 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
1049 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
1050 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
1051 gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
1052 gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
1053 gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
1054 gnulib/config/po.m4, gnulib/config/progtest.m4,
1055 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
1056 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
1058 2003-09-05 Gary V. Vaughan <gary@gnu.org>
1060 We can't mirror the gnulib directory structure here, since we need
1061 to be able to eg. `#include <m4/obstack.h>' from our source files,
1062 which is much easier if the local obstack.h is created in a
1063 directory named m4. Rather than trying to symlink everything into
1064 the m4 directory, now we build a libtool convenience library from
1065 the sources we get from gnulib and link that with libm4.la:
1067 * gnulib/config/extensions.m4: Imported from CVS gnulib.
1068 * gnulib/config/unlocked-io.m4: Ditto.
1069 * gnulib/m4/unlocked-io.h: Ditto.
1070 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
1071 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
1072 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
1073 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
1074 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
1075 * m4/Makefile.am: Adjust.
1076 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
1077 macros we redistribute.
1078 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
1079 library among others.
1080 (GNULIB_SRCS, GNULIB_MACROS): Removed.
1081 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
1082 * config/m4-obstack.m4: Adjust.
1083 * po/POTFILES.in: Adjust.
1084 * configure.ac: Reformatting. Call newly imported gnulib macros.
1085 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
1086 bogus calls of `#include "m4.h"'.
1087 * Makefile.am: INCLUDES has been deprecated in favour of
1089 * m4/Makefile.am: Ditto.
1090 * modules/Makefile.am: Ditto.
1091 * src/Makefile.am: Ditto.
1093 2003-09-05 Gary V. Vaughan <gary@gnu.org>
1095 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
1097 2003-09-04 Gary V. Vaughan <gary@gnu.org>
1099 Migrate the obstack support into the gnulib directories for easy
1100 synchronisation with upstream files in gnulib:
1102 * config/gnu-obstack.m4: Moved from here...
1103 * config/m4-obstack.m4: ...to here.
1104 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
1105 * m4/obstack.c, m4/obstack_.h: Moved from here...
1106 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
1107 * po/POTFILES.in: Adjust.
1108 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
1109 * m4/Makefile.am: Add a whole new section to link the obstack
1110 sources from the gnulib tree if necessary.
1111 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
1113 * config/m4-obstack.m4: Rewrite as a wrapper for
1114 gnulib/m4/obstack.m4.
1116 2003-09-04 Gary V. Vaughan <gary@gnu.org>
1118 GNU M4 currently builds with a number of files adapted from
1119 upstream sources. Recently the gnulib project on savannah.gnu.org
1120 has pulled together a great many of these externally maintained
1121 files. This delta is the beginnings of isolating those files
1122 maintained in gnulib to make it easy to synchronise M4 with the
1123 upstream files prior to releases.
1125 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
1127 (SUBDIRS): Added new gnulib subdirectory.
1128 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
1129 * config/stdbool.m4: Moved from here...
1130 * gnulib/m4/stdbool.m4: ...to here.
1131 * m4/stdbool_.h: Moved from here...
1132 * gnulib/lib/stdbool_.h: ...to here.
1133 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
1135 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
1136 code to work with new stdbool_.h location.
1137 (gnulib_srcdir): New.
1139 2003-09-04 Gary V. Vaughan <gary@gnu.org>
1141 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
1142 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
1144 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
1145 (EXTRA_DIST): Use it.
1147 * bootstrap: CVS autoreconf leaves file droppings. Remove
1148 aclocal.m4t incase autoreconf doesn't.
1150 2003-08-29 Gary V. Vaughan <gary@gnu.org>
1152 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
1153 the other gnulib imports, renamed to m4/obstack_.h.
1154 * m4/obstack.c: Updated from CVS gnulib.
1155 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
1156 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
1157 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
1158 about vpath already, and $top_srcdir upsets CVS Automake, so the
1159 $top_srcdir reference was removed.
1161 * m4/system-h.in: For consistency with the gnulib imports, renamed
1163 * m4/Makefile (EXTRA_HEADERS): Adjust.
1164 * configure.ac (AC_CONFIG_FILES): Adjust.
1166 * m4/stdbool_.h: New file from gnulib for systems without their
1168 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
1169 * config/stdbool.m4: New file. Macros from gnulib for same.
1170 * configure.ac: Use it.
1172 2003-08-27 Gary V. Vaughan <gary@gnu.org>
1174 * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'`

1221 * src/main.c: Ditto.
1222 * src/stackovf.c: Ditto.
1224 * config/gmp.m4 (M4_AC_LIB_GMP): Use AC_INCLUDES_DEFAULT:
1225 ac_default_headers is an autoconf internal variable.
1226 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
1227 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
1229 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
1230 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
1233 2003-08-15 Gary V. Vaughan <gary@gnu.org>
1235 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
1237 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
1238 possible or faking one with a typedef. Changed all callers.
1240 2003-08-15 Gary V. Vaughan <gary@gnu.org>
1242 Still cleaning up the users' module API, by taking out the stuff
1243 that isn't used by any existing modules, and moving specialised
1244 functions out of libm4 and into the module they are used by.
1246 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
1247 * m4/utility.c (m4_skip_space): ...to here the home of its only
1248 use, made static and renamed to `skip_space'. Changed all
1250 * m4/m4module.h (m4_expand_ranges): Removed prototype.
1251 * m4/utility.c (m4_expand_ranges): Moved definition from here...
1252 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
1254 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
1256 * modules/gnu.c (builtin_syntax): Import and use in this
1257 builtin implementation.
1258 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
1260 * m4/macro.c (trace_flush): Except here where the macro is now
1262 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
1263 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
1265 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
1266 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
1268 2003-08-14 Gary V. Vaughan <gary@gnu.org>
1270 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
1271 compiler based AC_CHECK_HEADER that was introduced in
1273 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
1274 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
1275 * configure.ac: Use renamed M4_AC_LIB_GMP.
1277 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
1278 macro that requires arguments! This stops the shell's bad
1279 substitution error at configure time.
1281 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
1282 variables to the testsuite shell. Set the value of USE_GMP so
1283 that the gmp test will run!
1284 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
1286 2003-08-11 Gary V. Vaughan <gary@gnu.org>
1288 Libltdl already has an excellent mechanism for accessing C symbols
1289 in modules. Lets use that! Remove all the exporting cruft and
1290 just use lt_dlsym in conjunction with a few conventions to
1291 simplify module writers' jobs. Also removed the table address
1292 caching code and otherwise simplified the module loader quite a
1293 bit. To access exported symbols in other modules, first the
1294 exporting module must name the symbols <modname>_LTX_<symname>,
1295 and the importing module must define a function type called
1296 <symname>_func. The importer then adds
1297 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
1298 that wishes to call out to the exported functions. Care must be
1299 taken that <symname> is non-NULL in the importing module incase
1300 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
1301 definition was in the importers source. Study
1302 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
1303 m4_module_import will attempt to automatically load a module
1304 required for symbol access if it is not loaded already.
1306 * TODO: Removed the items fixed in this delta.
1307 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
1309 * m4/ltdl.h (lt_dlhandle_find): Declare it.
1310 * m4/module.c (m4_module_unload): Use it.
1311 * src/freeze.c (reload_frozen_state): Ditto.
1312 * m4/m4module.h (m4_export): Deleted. Removed all references.
1313 (M4_MODULE_IMPORT): New user convenience macro for importing
1314 arbitrary symbols from other modules.
1315 * m4/module.c (m4_module_import): New function to service
1316 M4_MODULE_IMPORT macro.
1317 (module_data): Removed. Looking up the tables on demand with
1318 lt_dlsym, rather than caching their addresses here simplifies the
1320 (m4_get_module_builtin_table, m4_get_module_macro_table):
1321 Removed. Changed all callers.
1322 (set_module_macro_table, set_module_builtin_table): Renamed to
1323 install_macro_table and install_builtin_table respectively, and
1324 simplified now that the cache is no more.
1325 * modules/gnu.c (builtin_symbols): Use this new mechanism to
1326 import m4_dump_symbols from the m4 module.
1327 (builtin_esyscmd): Likewise for m4_set_sysval and
1329 * modules/m4.c (m4_export_table): Removed. Functions are
1330 addressed with the new mechanism which doesn't need this.
1331 (m4_set_sysval): New exported accessor function to prevent
1332 problems with variable access on inferior architectures.
1333 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
1334 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
1335 that we can have some type safety.
1336 * modules/modtest.c (export_test): C level exported function for
1337 testing the new import mechanism.
1338 * modules/import.c: New file for the import end of the test.
1339 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
1340 * tests/modules.at: New test cases for intermodule symbol
1343 2003-08-07 Gary V. Vaughan <gary@gnu.org>
1345 * m4/m4module.c (m4_string): Moved from here...
1346 * m4/m4private.c (m4_string): ...to here.
1348 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
1350 2003-07-29 Gary V. Vaughan <gary@gnu.org>
1352 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
1353 already available to module writers through
1354 m4_{get,set}_nesting_limit_opt(), so moved from here...
1355 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
1356 (m4_create): Use it.
1358 2003-07-28 Gary V. Vaughan <gary@gnu.org>
1360 Aside from auditing path.c for m4module.h api obfuscation, this
1361 delta introduces the concept of private struct members in opaque
1362 data types to GNU m4: See the STYLE file for details.
1364 * TODO: Remind ourselves that a rewrite of path.c is needed.
1365 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
1367 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
1368 here and renamed. These type definitions are for internal api use
1369 only. Changed all callers.
1370 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
1372 * m4/path.c (search_path_env_init, search_path_add): ...to here
1373 and renamed. These calls were never used outside this file.
1374 Changed all callers.
1375 (dirpath): Moved functionality of this static declaration...
1376 * m4/m4private.h (struct m4): ...to this new internal only
1377 search_path field. Changed all callers.
1378 (m4__get_search_path): Added new internal api accessor.
1379 * m4/path.c (m4_search_path_info_new): Removed. Not used.
1380 (m4_include_init): Removed...
1381 * m4/m4.c (m4_create): ...because the new m4 field is now
1383 (m4_delete): Recycle search_path memory.
1384 * src/main.c (main): Don't call m4_include_init now that it's
1386 * doc/STYLE: Document convention for private fields in opaque
1389 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1391 Sometimes exporting the address of a symbol from a module isn't
1392 enough for other modules to call that symbol correctly. If
1393 custom data types are used for function parameters, they need to
1394 be known to the caller. This change introduces the concept of
1395 $(prefix)/include/modules/$(modulename).h to declare those
1396 structures. Also we move m4_dump_symbols from libm4 to the m4
1397 module to show this concept in action.
1399 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
1400 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
1401 exporting data structures from modules/m4.c.
1402 * modules/m4.c, modules/gnu.c: Include it.
1403 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
1404 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
1406 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
1408 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
1409 ...to here, with slight renaming.
1410 (m4_export_table): Prototype and add m4_dump_symbols.
1411 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
1412 definition of m4_dump_symbols.
1413 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
1414 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
1416 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1418 Create an export table in modules/m4.c in readiness for beefing up
1419 the module loader to track module exports and imports.
1421 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
1422 * m4/debug.c (m4_debug_flush_files): Moved...
1423 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
1424 * modules/gnu.c (builtin_esysval): Use it.
1425 * m4/m4module.h (m4_export): New type for declaring module symbols
1427 * modules/m4.c (m4_export_table): List symbols exported from this
1428 module for use by other modules.
1430 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1432 An experiment: There is loads of code in libm4 which should be in
1433 the m4 module, but is also used by another module. Just because
1434 some linkers won't cope with calls across dynamic runtime loaded
1435 objects I initially left the code in libm4. It will tidy the
1436 module api immensely if this code moves to the right place, I just
1437 need to remember to invent a suitable calling mechanism at some
1438 point. For now, only modules that are statically linked and
1439 preloaded will get this treatment, so the only platforms that will
1440 break are those that require all symbols to be resolved at link
1443 * TODO: Reminder that what I am doing could reduce portability
1444 unless I do something more robust later.
1445 * m4/m4module.h (m4_sysval): No longer exported from libm4.
1446 * m4/utility.c (m4_sysval): No longer declared in libm4.
1447 * modules/Makefile.am: Reformatting.
1448 * modules/m4.c (m4_sysval): Declare it at place of use.
1449 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
1451 2003-07-23 Gary V. Vaughan <gary@gnu.org>
1453 * m4/m4module.h: Reformatting and rearranging lines a bit.
1454 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
1456 (m4_call_macro, m4_expand_input): Renamed...
1457 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
1459 (m4_expansion_level, m4_process_macro): Moved...
1460 * m4/macro.c (expansion_level, process_macro): ...to here, and
1463 * m4/m4module.h (program_name): Not used by modules at all, so
1465 * src/main.c (program_name): ...to here.
1466 (print_program_name): Renamed...
1467 (print_program_name_CB): ...to conform to the STYLE guide.
1469 2003-07-23 Gary V. Vaughan <gary@gnu.org>
1471 More refactoring of the m4module.h API. Replace #defines with an
1472 enum, and move non-public functions out of the public API.
1474 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
1476 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
1477 * m4/debug.c (m4_debug, trace): Moved...
1478 * m4/m4private.h (struct m4): ...to fields of this struct.
1479 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
1481 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
1482 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
1483 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
1484 * m4/m4module.h (m4_context_field_table): Add entries for new
1485 debug_file and trace_messages fields.
1486 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
1487 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
1488 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
1489 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
1490 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
1491 (m4_is_debug_bit): New macro to simplfy checks against the debug
1493 (m4_trace_format, m4_trace_header, m4_trace_flush)
1494 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
1496 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
1497 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
1498 * m4/macro.c (trace_format, trace_header, trace_flush)
1499 (trace_prepre, trace_pre, trace_post): ...to these newly static
1500 functions, since they are only ever used from this file. Changed
1503 2003-07-17 Gary V. Vaughan <gary@gnu.org>
1505 Change the macros for checking syntax so that matching against
1506 multiple possible syntax classes can be done with a single
1507 comparison some of the time. The various classes are now bits of
1508 an int that can be checked with bitwise logic operators.
1510 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
1511 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
1512 (M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)
1513 (M4_SYNTAX_ASSIGN, M4_SYNTAX_ALPHA, M4_SYNTAX_NUM)
1514 (M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)
1515 (M4_SYNTAX_ECOMM): Replaced #defines with an enum.
1516 (M4_SYNTAX_ALNUM): Removed. Changed all callers.
1517 (M4_IS_IGNORE, M4_IS_OTHER, M4_IS_SPACE, M4_IS_OPEN, M4_IS_CLOSE)
1518 (M4_IS_COMMA, M4_IS_DOLLAR, M4_IS_ACTIVE, M4_IS_ESCAPE)
1519 (M4_IS_ASSIGN, M4_IS_ALPHA, M4_IS_NUM, M4_IS_LQUOTE, M4_IS_RQUOTE)
1520 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
1521 Replace all calls with invocations of these...
1522 (m4_is_syntax, m4_has_syntax): ...New macros.
1523 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
1524 is no longer required with new macros. Changed all callers.
1526 2003-07-15 Gary V. Vaughan <gary@gnu.org>
1528 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
1529 values are returned as part of the internal interface, so they
1531 * m4/private.h: ...to here.
1532 * m4/macro.c (expand_token): Check for out of range
1533 m4_peek_input() results before looking up in the syntax table.
1534 (collect_arguments): Ditto.
1536 * NEWS: Note `$' syntax class.
1538 2003-07-08 Paul Eggert <eggert@twinsun.com> and
1539 Gary V. Vaughan <gary@gnu.org>
1541 Conform to POSIX if the POSIXLY_CORRECT environment is set.
1542 --traditional `define' now smashes all the definitions.
1544 * NEWS: Explain this.
1545 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
1546 (Extensions): Explain that extensions that are incompatible with
1547 POSIX are disabled if POSIXLY_CORRECT is set.
1548 (Incompatibilities): Remove.
1549 (Define, Other Incompat): Explain difference
1550 between GNU and POSIX behavior of define, pushdef, popdef.
1551 * m4/m4.c (m4_get_posixly_correct_opt): New undef.
1552 * m4/m4module.h (m4_context_opt_bit_table): Add POSIXLY_CORRECT entry.
1553 * m4/m4private.h (M4_OPT_POSIXLY_CORRECT_BIT): New macro.
1554 (m4_get_posixly_correct_opt): New macro.
1555 * m4/m4macro.c (m4_process_macro): Disable $10, $abc etc. if
1557 * modules/m4.c (builtin_functions): defn now takes any number of args.
1558 (builtin_define): Smash all the definitions if
1560 (builtin_defn)): Allow any number of arguments.
1561 (builtin_undivert): Do not allow nonnumeric arguments
1563 * src/main.c (main): Set posixly-correct behavior if either
1564 POSIXLY_CORRECT is set, or if -G is given.
1565 * tests/builtins.at: New test for smashed definitions.
1567 2003-06-27 Gary V. Vaughan <gary@gnu.org>
1569 * doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
1570 * m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
1571 not to slow the parser down.
1572 (M4__IS_STRING): New macro to test string syntax class membership.
1573 * m4/syntax.c: Adjust docucomment.
1574 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
1575 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
1576 * m4/input.c (init_builtin_token): Comment typo.
1577 (m4__next_token): Comment typo.
1578 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
1579 by using the new M4__IS_STRING macro.
1580 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
1581 variable references in macro expansions.
1583 * doc/m4.texinfo (Eregexp and Regexp): Typo.
1584 (Epatsubst and Patsubst): Typo.
1587 2003-06-26 Gary V. Vaughan <gary@gnu.org>
1589 Move the global variables that pertain to syntax to a new `struct
1590 m4_syntax_table', and then add one of these to `struct m4'. The
1591 ripple effect through the code to both change formerly global
1592 references, and make sure a suitable context is available in
1593 lexical scope is disproportionately large compared to the size of
1594 the change proper. This change is a large part of decoupling
1595 syntax.c from the rest of the code that uses it.
1597 * m4/m4private.h (struct m4): Add a syntax field.
1598 * m4/m4.c (m4_create): Initialise it,
1599 (m4_delete): Recycle it.
1600 (m4_get_symtab): Remove hand coded version...
1601 (m4_get_symbol_table): ...and generate this with cpp. Changed all
1603 * m4/m4module.h (m4_context_field_table): Add an extra field so we
1604 can generate m4_get_symbol_table. Add a new row for
1605 m4_get_syntax_table.
1606 (M4SYNTAX): Syntactic sugar for module writers.
1607 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
1608 (m4_syntax_table): New home for syntax related formerly global
1610 * m4/m4private.h (struct m4_syntax_table): Define it.
1611 * m4/input.c (m4_input_init): Initialisation of these formerly
1612 global variables moved...
1613 * m4/syntax.c (m4_syntax_create): ...to here.
1614 * m4/input.c (m4_input_exit): And similarly, recycling of the
1615 memory used by those values moved...
1616 * m4/syntax.c (m4_syntax_delete): ...to here.
1617 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
1618 Moved to m4/m4private.h.
1619 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
1620 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
1621 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
1622 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
1623 objects. Changed all callers that used to directly access the
1625 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
1626 Removed and incorporated into m4_syntax_table structure.
1627 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
1628 * m4/syntax.c (m4_set_syntax): Now returns an error status,
1629 instead of requiring a `struct m4' to generate its own errors.
1630 Changed all callers.
1631 * src/main.c (main): Now that the syntax table is initialised as
1632 part of m4_create, we have to manually wipe the syntax entries if
1633 we are about to read a frozen file.
1635 2003-06-26 Gary V. Vaughan <gary@gnu.org>
1637 * doc/STYLE: Added notes on callback naming schemes.
1639 * m4/module.c (m4_set_module_macro_table)
1640 (m4_set_module_builtin_table): Declarations weren't changed when
1641 definitions were renamed on 2003-06-19.
1643 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
1644 neither used nor particularly appropriate since it exposes the
1645 internal workings of the hash module. I haven't yet decided
1646 whether to remove it entirely.
1648 2003-06-20 Gary V. Vaughan <gary@gnu.org>
1650 Two related changes, and a huge knockon effect throughout the
1651 source: Moved the option variables out of global space and into
1652 `struct m4'; made `m4_symtab' a real datatype, so that its api
1653 is not marred passing `struct m4' around just so it can decide
1654 whether to keep traced symbol names or not. Added setters and
1655 getters for the formerly global option variables, and obviously
1656 changed a vast number of functions to take a `struct m4' and use
1657 the getter funcs to find option values.
1659 * m4/utility.c (interactive, sync_output, debug_level)
1660 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
1661 (max_debug_argument_length, warning_status, nesting_limit)
1662 (discard_comments): Removed.
1663 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
1664 (debug_level, max_debug_argument_length, prefix_all_builtins)
1665 (suppress_warnings, discard_comments, interactive, sync_output):
1666 Removed from here...
1667 * m4/m4private.h (struct m4): ...and equivalent fields added to
1669 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
1670 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
1671 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
1672 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
1673 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
1674 macros for the new fields.
1675 * m4/m4module.h (m4_context_field_table)
1676 (m4_context_opt_bit_table): Helper macros used to generate
1677 prototypes, setters and getters for new option fields
1679 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
1680 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
1681 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
1682 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
1683 (m4_get_interactive_opt, m4_get_sync_output_opt)
1684 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
1685 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
1686 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
1687 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
1688 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
1689 setter and getter functions generated by cpp from
1690 m4_context_field_table and m4_context_opt_bit_table, exported as
1691 part of the module api. Changed all callers.
1692 * m4/symtab (struct m4_symtab): Used as the concrete type for
1694 (m4_symtab_create): Allocate and initialise a new struct.
1695 (m4_symtab_apply): New function that works like m4_hash_apply, but
1696 with different callbacks specific to symbol tables. Changed all
1698 (symbol_destroy, arg_destroy, arg_copy): Renamed
1699 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
1700 they have unused parameters for a reason!
1701 (dump_symbol_CB): New callback to dump the contents of a single
1703 (symtob_dump): Rewritten in terms of dump_symbol_CB.
1704 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
1705 Changed all callers.
1706 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
1707 of the contained `m4_symtab' at the `no_gnu_extensions' field.
1708 Although I'm not convinced these semantics are correct, they are
1709 at least consistent with how things were before this delta. Also
1710 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
1712 2003-06-19 Gary V. Vaughan <gary@gnu.org>
1714 Tie down the interface to libm4 some more. Make more structures
1715 opaque to modules by moving them to m4private.h, and writing
1716 setters and getters. To win back the speed penalty for doing this
1717 also wrote macroized versions that do know about structure layout
1718 in m4private.h and #include that file into modules when NDEBUG is
1719 defined at compile time. There are still some accessor macros in
1720 m4private.h that need to go, but that is not necessary to clean
1723 * m4/m4module.h (m4_symbol_type): Moved...
1724 * m4/m4private.h (m4__symbol_type): ...to here.
1725 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
1726 (m4_set_symbol_traced, m4_set_symbol_name_traced)
1727 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
1728 (m4_get_symbol_func, m4_symbol_value_create)
1729 (m4_symbol_value_delete, m4_set_symbol_value_text)
1730 (m4_set_symbol_value_func): New exported api to symbols.
1731 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
1732 and m4_is_symbol_value_func.
1733 * m4/m4module.h: Prototype these guys.
1734 * m4/module.c (m4_set_module_macro_table)
1735 (m4_set_module_builtin_table): Make these static, there is no
1736 reason to pollute the api with them.
1737 * m4/m4private.h: Reformatting.
1738 (m4_get_symtab): Only define when NDEBUG is defined.
1739 (m4_get_symbol_value, m4_get_symbol_traced)
1740 (m4_set_symbol_traced, m4_set_symbol_name_traced)
1741 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
1742 (m4_get_symbol_func, m4_symbol_value_create)
1743 (m4_symbol_value_delete, m4_set_symbol_value_text)
1744 (m4_set_symbol_value_func): Macro implementations of the new
1745 functions when NDEBUG is defined.
1746 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
1747 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
1748 Superceded by the above. All callers changed.
1749 (M4ARG): Removed. This is no longer different to the
1750 m4/m4module.h definition.
1751 * modules/gnu.c, modules/m4.c: Only include m4private.h when
1752 NDEBUG is defined. That way we exercise the same (albeit slower)
1753 api that external modules must use.
1755 2003-06-18 Gary V. Vaughan <gary@gnu.org>
1757 Renamed some of the types and their accessors to make more sense.
1758 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
1759 has a stack of SYMBOL_VALUEs.
1761 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
1762 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
1763 m4_get_symbol_value_type, m4_get_symbol_value_text,
1764 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
1765 Changed all callers.
1766 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
1767 (m4_get_token_type): Renamed
1768 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
1769 to the internal api.
1770 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
1772 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
1773 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
1774 (m4__token_type): Moved here from m4module.h.
1775 (m4__next_token): Renamed from m4_next_token.
1776 * m4/symtab.c: Removed some of the parameterised macro support
1777 functions for modularisation later.
1778 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
1779 m4_hash_dup to perform a true deep copy of the SRC.
1780 (arg_copy): Callback for m4_symbol_value_copy.
1781 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
1782 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
1783 m4_get_symbol_value_func. Changed all callers.
1785 2003-06-18 Gary V. Vaughan <gary@gnu.org>
1787 Tidy up style of hash.[ch] in accordance with doc/STYLE.
1789 * m4/hash.c: Internal symbol renaming and formatting.
1790 (m4_hash_dup): New function to facilitate deep copies of hash
1792 (m4_hash_apply_func): Returns a void* now, which is a richer type
1793 for returning exceptions (NULL means keep going).
1794 (m4_hash_apply): Ditto.
1795 * m4/hash.h: Declare exported symbols with an explicit extern.
1798 2003-06-17 Gary V. Vaughan <gary@gnu.org>
1800 Still refactoring furiously. This delta represents a change in
1801 semantics to symtab.c. Instead of building temporary m4_tokens
1802 in the caller, and copying fields in the methods, we now create
1803 the actual m4_token for hashing in the caller so the methods just
1804 slot them in directly. Also, this means that we don't lookup a
1805 symbol and get back an allocated but VOID token to copy fields
1806 into, we create the token we want to push and pass that to
1807 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
1808 a few other small changes to stop knowledge of the implementation
1809 of symtab.c leaking out into other files.
1811 * m4/macro.c (expand_argument): Comment typo corrected.
1812 * m4/symtab.c (symtab_fetch): New function to fetch the address of
1814 (m4_symbol_pushdef): Take an extra value parameter and use this
1815 directly as the new top of the value stack. All callers changed
1816 to build a token and pass responsibility for memory in, rather
1817 than copying as we used to.
1818 (m4_symbol_define): Also use the new value parameter directly as a
1819 replacement for the top of the value stack. All callers changed
1820 to build a token as above.
1821 (m4_set_symbol_traced): New function to set the traced bit on the
1822 named symbol, creating it if necessary.
1823 (symbol_popval): The guts of the old m4_symbol_popdef.
1824 (m4_symbol_popdef): Use it.
1825 * m4/builtin.c (m4_symbol_set_token): Removed,
1826 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
1828 * m4/module.c (m4_set_module_builtin_table)
1829 (m4_set_module_macro_table): ...with these more orthogonal
1831 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
1832 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
1834 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
1835 (m4_arg_signature_parse): Moved...
1836 * m4/symtab.c: ...to here.
1837 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
1838 screw something up. Moved...
1839 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
1840 actually does a proper deep copy of source to dest.
1842 2003-06-16 Gary V. Vaughan <gary@gnu.org>
1844 Further refactoring to stabilise the module API. Renaming some
1845 functions for orthogonality, and judicious definition migration to
1846 move things out of the set of exported symbols.
1848 * doc/STYLE: New file. Notes on coding style.
1849 * m4/m4module.c: Updated bitrotted docucomment at the top of the
1851 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
1852 m4_get_module_name, m4_get_module_builtin_table,
1853 m4_get_module_macro_table which are verb phrases. Changed all
1855 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
1857 * m4/module.c (m4_set_module_builtin_table)
1858 (m4_set_module_macro_table): ...here, and renamed. Changed all
1860 * m4/m4module.c (m4_module_data): This...
1861 * m4/m4private.c (struct m4_module_data): ...and this...
1862 * m4/module.c (module_data) ...consolidated here and no longer
1863 exported. Changed all callers.
1865 2003-06-16 Gary V. Vaughan <gary@gnu.org>
1867 Begin work on lifting the curse of the global variables. To start
1868 with create a `struct m4' context container, and replace
1869 `m4__symtab' with `context->symtab' throughout. This means
1870 initialising a context container in main, and adjusting many
1871 functions between main and the module entry points so that the
1872 container gets passed through. It would have been nice to
1873 defer this until after 1.5, but it has a major effect on the
1874 user's module writing ABI, so it needs to be addressed now - at
1875 least in the areas that impact the ABI. An interrelated change
1876 in the symtab API removes the dependency on a global symbol table,
1877 and instead focuses on a passed table (from the context
1880 * TODO: Reminders for finishing context functionality.
1881 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
1882 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
1883 global variables and eventually allow m4 to be reentrant.
1884 * m4/m4private.h (m4): Define the new structure here...
1885 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
1886 don't carry the overhead of a function call.
1887 * m4/m4module.h: Prototype extern functions from m4/m4.c.
1888 (m4): Declare type for new struct m4 objects.
1889 (M4SYMTAB): User macro to ease finding the symbol table for the
1890 current context for module developers.
1891 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
1893 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
1894 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
1895 (m4_call_macro, m4_dump_symbols, m4_expand_input)
1896 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
1897 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
1898 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
1899 m4* context parameter. Changed definitions and all callers.
1900 (m4_symtab): Alias for m4_hash to decouple the
1901 m4_symtab api from m4_hash.
1902 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
1904 (m4_symtab_create): New function to return an initialised
1906 (m4_symtab_delete): New function to delete an m4_symtab's memory.
1907 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
1908 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
1909 instead of simply using the global m4__symtab. Changed
1910 definitions and all callers.
1911 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
1912 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
1913 * src/main.c (main): Create a context and use that instead of the
1914 former global m4__symtab.
1916 2003-06-13 Gary V. Vaughan <gary@gnu.org>
1918 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
1919 to the callback. Callbacks should not need to hardcode the
1920 hashtable they are working from, nor should we have to waste the
1921 userdata parameter to pass the table in.
1922 * m4/hash.h (m4_hash_apply_func): Require the initial table
1924 * m4/symtab.c (symtab_destroy): Use the passed table instead
1925 of hardcoding m4__symtab.
1926 (m4_symbol_popdef): Don't use the userdata parameter to pass the
1927 table to arg_destroy.
1928 (arg_destroy): Use the hash parameter, ignore userdata.
1929 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
1931 (traceon, traceoff): Call set_trace with the extra initial
1934 2003-06-13 Gary V. Vaughan <gary@gnu.org>
1936 More refactoring to stabilise the module api, this time for
1937 symtab.c. Additionally, start to pay attention to function names
1938 that don't contain a verb like they should.
1940 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
1941 wrapper for m4_hash_apply to decouple the symtab module from the
1943 (m4_symbol_builtin, m4_symbol_macro): Renamed to
1944 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
1946 (m4_symbol_delete): Create a macro version to save a function
1948 (m4_token_t, m4_data_t): These violate the POSIX reserved
1949 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
1951 (m4_token_type): Renamed to m4_token_get_type.
1952 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
1953 (m4_symtab_exit): Removed from the exported module
1955 * m4/m4private.h (m4__symtab, m4__symtab_init)
1956 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
1957 renamed and added to the internal api. Changed all callers.
1958 (m4_symtab_apply): A faster macro version of the function for
1959 users of the internal api.
1960 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
1961 symbol_destroy and arg_destroy.
1962 (symtab_debug): Added a prototype.
1963 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
1964 so that callers in this file get the faster macro versions from
1967 2003-06-12 Gary V. Vaughan <gary@gnu.org>
1969 Refactoring modules to rationalise the API into an external
1970 documented (eventually!) API for use by modules in the `m4_'
1971 namespace declared in m4/m4module.h, an internal API between the
1972 source files we ship (including our shipped modules) in the `m4__'
1973 namespace declared in m4/m4private.h and making the rest as
1974 cohesive as possible with liberal use of the `static' keyword.
1975 This change represents an audit to m4/module.c along these
1978 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
1979 Removed. No longer used.
1980 (m4_module_close): Removed prototypes.
1981 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
1982 from the exported module api...
1983 * m4/m4private.h (m4__module_init, m4__module_open)
1984 (m4__module_exit): ...and renamed and added to the internal api.
1985 Changed all callers.
1986 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
1987 Centralised definitions after renaming...
1988 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
1989 (M4_FINISH_SYMBOL): ...and removing from here.
1990 (m4_module_dlerror, m4_module_remove, m4_module_close)
1991 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
1992 module_remove, module_close and caller_id.
1993 (MODULE_SELF_NAME): New macro to make reporting self errors
1995 (m4_module_load, module_close, module_remove): Use it.
1996 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
1998 * src/main.c (main): Use it.
2000 2003-06-12 Gary V. Vaughan <gary@gnu.org>
2002 * README: Remove references to --enable-changeword, which has been
2003 removed from the code.
2005 2003-06-11 Gary V. Vaughan <gary@gnu.org>
2007 Getting rid of the annoying bug with configure --enable-debug,
2008 which spewed -e: command not found errors. This was an interaction
2009 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
2010 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
2011 branch-1-5) to get the full fix.
2013 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
2014 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
2015 and then use the probed value of $SED.
2016 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
2017 this, it messes up the AC_REQUIRE stack.
2019 2003-06-10 Gary V. Vaughan <gary@gnu.org>
2021 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
2022 the destroy callback.
2023 (m4_arg_destroy): Use the hash address to free the hash node key
2026 2003-06-06 Gary V. Vaughan <gary@gnu.org>
2028 First cut at formal parameters in macros.
2030 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
2031 * m4/xstrzdup.c: New file.
2032 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
2033 associative array of parameter names to details.
2034 (m4_symbol_token): Capture macro names with parameter lists.
2035 (m4_arg_signature_parse): And build an associative array to hang
2036 from the symbol structure to map names to details.
2037 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
2038 m4_hash_resize idiom. Now that we potentially add a little hash
2039 table to many of the entries in the symbol table, added an extra
2040 arg to set the initial size. Changed all callers.
2041 (m4_hash_apply): New function that is basically a generalised
2043 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
2044 all callers to call m4_hash_apply instead.
2045 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
2046 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
2047 m4_arg_signature association that might be attached to the symbol,
2048 * m4/hash.h (m4_hash_apply_func): Replacement type for...
2049 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
2050 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
2052 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
2053 (M4_IS_IDENT): Detect characters that can be safely used in
2055 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
2056 * m4/macro.c: Corrected grammar in some comments. Use `token'
2057 rather than `td' for m4_token variables.
2058 (m4_process_macro): If we find a dollar followed by some
2059 M4_IS_IDENT characters, replace that with the contents of the argv
2060 entry with offset stored in the m4_token_arg associated with the
2061 collected identifier.
2063 2003-06-05 Gary V. Vaughan <gary@gnu.org>
2065 Begin preparations for supporting formal parameters in m4 macros.
2067 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
2068 the details of a formal parameter.
2069 (m4_token): Add an arg_signature member to hold a hash table for
2070 looking up formal parameters.
2071 * m4/input.c: Update more bitrotted comments.
2072 (m4_push_builtin): Initialise arg_signature member.
2073 (init_builtin_token): Copy arg_signature member.
2074 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
2075 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
2077 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
2078 (m4_macro_pushdef, m4_macro_define): ...these, And...
2079 (m4_symbol_token): ...wrapped around this new function, which
2080 vastly simplifies the arguments required by the functions it
2082 Changed all callers.
2084 2003-06-05 Gary V. Vaughan <gary@gnu.org>
2086 * m4/macro.c: Format changes.
2088 2003-06-04 Gary V. Vaughan <gary@gnu.org>
2090 * m4/input.c: Updated various bitrotted comments.
2091 (m4_push_builtin): Just pass the whole m4_token, rather than
2092 extracting all the fields in the caller. This also allows us to
2093 check the token type for consistency.
2094 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
2095 Renamed to builtin_funcs, builtin_peek, builtin_read,
2096 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
2097 the code. Changed all callers.
2098 (struct input_block): Similarly renamed u_m member to u_b, and
2099 changed all callers.
2100 (m4_next_token): Use bzero to initialise the data fields.
2101 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
2103 2003-05-29 Gary V. Vaughan <gary@gnu.org>
2105 These changes were necessary to get m4 to build on my iBook
2106 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
2107 (GCC) 3.1 20020420 (prerelease)":
2109 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
2110 inclusion of module loader headers.
2111 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
2112 * m4/Makefile.am: Ditto.
2113 (libm4_la_LIBADD): Added $(LTLIBINTL).
2114 * m4/utility.c (program_name): Removed declaration in favour of
2115 the one already in error.c!
2116 * m4/m4module.h (program_name): Define to program_invocation_name
2117 when using GNU C library. Use an explicit extern declaration.
2118 (interactive, sync_output, debug_level, hash_table_size)

2128 (m4_current_line, m4_current_diversion, m4_output_current_line):
2129 Don't rely on default, use an explicit extern.
2130 * m4/error.h (error, error_at_line, error_print_progname)
2131 (error_message_count, error_one_per_line): Ditto.
2132 * m4/ltdl.c: Update from CVS libtool.
2134 * commit: Update from CVS cvs-utils.
2136 2002-11-04 Akim Demaille <akim@epita.fr>
2138 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
2140 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
2142 2002-11-04 Akim Demaille <akim@epita.fr>
2144 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
2146 2002-11-04 Akim Demaille <akim@epita.fr>
2148 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
2149 used as `external', and Libtool 1.4.3.
2151 (LTLIBOBJS): Don't play with it.
2153 * Makefile.am (SUBDIRS): Remove intl.
2154 (ACLOCAL_AMFLAGS): Add -I config.
2155 (EXTRA_DIST): Add config/config.rpath.
2158 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
2160 2002-05-29 Gary V. Vaughan <gary@gnu.org>
2162 Preparations for refactoring syntax tables to allow reverse
2163 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
2164 speed of normal lookups in an array of unsigned short.
2166 * m4/input.c (single_quotes, single_comments, use_macro_escape):
2168 * m4/m4private.h (m4__single_quotes, m4__single_comments,
2169 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
2170 is for internal symbols which unavoidably pollute the global
2171 namespace, but are not published APIs.
2172 Adjusted all callers.
2173 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
2174 m4_set_comment, m4_set_syntax, set_syntax_internal,
2175 unset_syntax_attribute): Moved from this file...
2176 * m4/syntax.c: New. ...to this file.
2177 Also added an m4_syntax_exit stub for orthogonality.

2180 * m4/m4module.h: Reformatting. New prototypes.
2182 2002-05-29 Gary V. Vaughan <gary@gnu.org>
2184 * bootstrap (aclocal_apiversion): The aclocal apiversion is
2185 distinct from the automake release number (in that the apiversion
2186 apparently has no micro-version-component).
2187 (aclocal_apilibdir): Use it.
2189 2002-05-28 Gary V. Vaughan <gary@gnu.org>
2191 * m4/hash.c (m4_hash_resize): New function.
2192 * m4/hash.h: Add prototype.
2193 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
2194 benchmarking to find a good value for, say, autoconf. This is
2195 already a little quicker than before for me.
2197 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
2198 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
2200 * m4/hash.h: Adjust prototypes.
2202 2002-01-22 Akim Demaille <akim@epita.fr>
2204 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
2206 * tests/Makefile.am (package.m4): New.
2207 * tests/atlocal.in: Adjust to CVS Autotest.
2208 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
2209 * configure.ac: LIBOBJ is a forbidden string.
2210 Simplify AM_INIT_AUTOMAKE invocation.
2211 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
2214 2001-10-19 Akim Demaille <akim@epita.fr>
2216 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
2218 2001-10-19 Akim Demaille <akim@epita.fr>
2220 * m4/input.c (m4_next_token): Display where was opened what is
2223 2001-10-19 Akim Demaille <akim@epita.fr>
2225 * m4/macro.c (expand_argument): Display where was opened what is
2228 2001-10-18 Akim Demaille <akim@epita.fr>
2230 * m4/input.c, modules/m4.c: Formatting changes.
2232 2001-10-17 Gary V. Vaughan <gary@gnu.org>
2234 * bootstrap: s/configure.in/configure.ac/
2236 2001-10-16 Gary V. Vaughan <gary@gnu.org>
2238 * m4/symtab.c (m4_symbol_destroy): This function calls
2239 m4_symbol_popdef, which recycles a symbols memory when the last
2240 definition is popped. Since we were passing the address of the
2241 symbol name found in the symbol table, and it was being removed
2242 partway through m4_symbol_destroy() we were referencing freed
2243 memory for the balance of the function. Now we take a copy of the
2244 symbol name tring and use that as a key into the symbol
2245 table... that way if the original symbol name is freed, the copy
2248 2001-10-13 Akim Demaille <akim@epita.fr>
2250 * m4/ltdl.c: Update.
2252 2001-10-13 Akim Demaille <akim@epita.fr>
2254 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
2255 Don't gettextize internal error messages.
2257 2001-10-13 Akim Demaille <akim@epita.fr>
2259 * tests/macros.at (Arity and defn): New failing test.
2260 (Arity, defn, and freeze): New.
2262 Fix `Arity and defn'.
2264 * m4/input.c (m4_push_macro): Don't forget the arity.
2265 * modules/m4.c (defn): Likewise.
2267 2001-10-13 Akim Demaille <akim@epita.fr>
2269 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
2271 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
2272 (Propagation of traceon, Propagation of --trace): this new file.
2274 2001-10-13 Akim Demaille <akim@epita.fr>
2276 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
2277 interface instead of (name, argc...).
2278 Upon failure, specify which argument was guilty.
2281 2001-10-13 Akim Demaille <akim@epita.fr>
2283 * modules/evalparse.c: Save translators' time: don't translate
2284 internal error messages.
2285 (m4_evaluate): Simplify/normalize error messages.
2286 * doc/m4.texinfo (Eval): Adjust.
2288 2001-10-13 Akim Demaille <akim@epita.fr>
2290 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
2291 where no checking is needed.
2292 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
2293 interface instead of (name, argc...).
2295 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
2298 2001-10-13 Akim Demaille <akim@epita.fr>
2300 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
2301 exclude the builtin name from the count.
2302 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
2303 calling ifelse with a single argument is valid.
2304 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
2305 with 1 and 2 args, mostly to strengthen the test suite.
2307 2001-10-13 Akim Demaille <akim@epita.fr>
2309 * m4/output.c (m4_make_diversion, m4_insert_file)
2310 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
2312 2001-10-12 Gary V. Vaughan <gary@gnu.org>
2314 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
2315 since we call these things builtins in the rest of the code!
2317 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
2319 2001-10-12 Gary V. Vaughan <gary@gnu.org>
2321 Rather than forcing each builtin definition to manage its own
2322 argument range checking, tabulate the maxima and minima for all
2323 builtins in each module. This forces us to consider what the
2324 valid ranges for each builtin should be, and moves the checking
2325 code out of each builtin implementation and into the builtin
2326 caller infrastructure.
2328 * m4/m4module.h (struct m4_builtin): Add argument minima and
2330 * m4/m4private.h (struct m4_token): Reflect them here too.
2331 * m4/input.c (struct input_block): ...and here.
2332 (m4_token_copy): New function for token copying.
2333 (init_macro_token): Copy them from a token to the input stack.
2334 (m4_next_token): Don't forget to initialise them for text
2336 * m4/macro.c (expand_argument): Use m4_token_copy, and also
2337 check argument counts before calling the builtin handler.
2338 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
2339 (m4_symbol_macro): Likewise.
2340 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
2341 parameters. Updated all callers.
2342 (m4_builtin_define): Ditto.
2343 (m4_macro_pushdef, m4_macro_define): Ditto.
2344 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
2345 * modules/evalparse.c: Declare argument counts for defined
2346 builtins and remove explicit calls to m4_bad_argc().
2347 * modules/gnu.c: Ditto.
2348 * modules/load.c: Ditto.
2349 * modules/m4.c: Ditto.
2350 * modules/modtest.c: Ditto.
2351 * modules/mpeval.c: Ditto.
2352 * modules/perl.c: Ditto.
2353 * modules/shadow.c: Ditto.
2354 * modules/stdlib.c: Ditto.
2355 * modules/time.c: Ditto.
2358 2001-10-10 Gary V. Vaughan <gary@gnu.org>
2360 The trace semantics now attach the trace bit to a symbol name.
2361 For as long as a traceon(`foo') is active, calls to foo will be
2362 traced regardless of intervening undefines or module unloads.
2363 Fixed the flag propogation issues differently to the fixes
2364 reverted with the last attempt at nailing down trace:
2366 * m4/m4private.h: This file is not visible outside of the m4
2367 source tree, so I removed all the `M4_' and `m4_' prefixes to save
2368 on typing. Updated all clients.
2369 (m4_token): New typedef contains the fields that need to be passed
2370 around with the low level tokeniser.
2371 (m4_token_data): Removed.
2372 (m4_symbol): Now contains the traced flag again.
2373 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
2374 the trace bit set. This change is contained entirely within this
2375 module and doesn't leak out into the callers. Updated all
2377 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
2378 new fields in m4_token. Updated all clients.
2379 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
2380 that `groks_macro_args' and `blind_if_no_args' flags are retained
2381 when defn() results are passed around in m4 code. Updated all
2383 (m4_builtin_define): Ditto.
2384 (m4_macro_pushdef, m4_macro_define): Ditto.
2385 * m4/input.c (struct input_block): Add a flags field to facilitate
2387 (m4_push_macro): ...use it.
2388 (init_macro_token): Retrieve it.
2389 (m4_next_token): Initialise it.
2390 * m4/macro.c (expand_argument): Copy it.
2391 * m4/m4module.h: Adjust.
2392 * tests/builtins.at: Adjust the expected output of the trace
2393 tests to reflect the change in semantics.
2394 * tests/modules.at (modules: trace): Check that unloading a
2395 module which supplies a traced symbol definition doesn't lose te
2398 2001-10-07 Gary V. Vaughan <gary@gnu.org>
2400 * modules/gnu.c (m4_macro_table): Display the timetamp when
2401 expanding __m4_version__.
2403 * configure.ac (--with-modules): Forgot a comma in the
2404 AC_HELP_STRING parameter list.
2406 2001-10-05 Gary V. Vaughan <gary@gnu.org>
2408 * bootstrap: Remove aclocal.m4t when it is no longer required.
2410 2001-10-05 Akim Demaille <akim@epita.fr>
2412 * tests/Makefile.am: Adjust for gnuprog2.
2413 * tests/m4.in: There can be a leading path.
2414 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
2415 * tests/testsuite.at: Adjust to the most recent Autotest.
2416 (AT_CHECK_M4_FILTER): Fix and rename as...
2418 * tests/others.at: Use it.
2420 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
2421 variable in shell scripts, one uses `$'...
2423 2001-10-04 Gary V. Vaughan <gary@gnu.org>
2425 * configure.ac: `rm -f $m4_getopt_h' was lost.
2427 2001-10-04 Gary V. Vaughan <gary@gnu.org>
2429 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
2430 time. Define it for config.h in order to...
2431 * src/main.c (main): ...display the timestamp for --version.
2433 2001-10-04 Akim Demaille <akim@epita.fr>
2435 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
2436 previous builtins `regexp' and `patsubst'.
2437 (regexp, patsubst): Use them.
2438 (eregexp, epatsubst): New builtins.
2439 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
2440 (Epatsubst and Patsubst, Eregexp and Regexp): these.
2441 (Extensions): More info on REs.
2443 2001-10-04 Akim Demaille <akim@epita.fr>
2445 * modules/modtest.c (init_handler): Consistently output to stderr.
2446 (finish_handler): New.
2447 (test): The `if' is an `assert'.
2448 * tests/modules.at: Adjust.
2450 2001-10-04 Akim Demaille <akim@epita.fr>
2452 * m4/utility.c (m4_bad_argc): Detail the mismatches.
2454 2001-10-01 Akim Demaille <akim@epita.fr>
2456 * tests/generate.awk: Tag the tests with `documentation'.
2457 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
2458 Use the make the existing modtest tests more uniform, and complete
2459 the set of possibilities.
2461 2001-10-01 Akim Demaille <akim@epita.fr>
2463 * config/gmp.m4: Consult the user before using GMP: use
2465 * configure.ac: Adjust.
2466 * modules/gmp.c: No protection needed as the module is not built
2469 2001-10-01 Akim Demaille <akim@epita.fr>
2471 * tests/generate.awk: Remove debugging code.
2472 (fatal): Specify the current location.
2474 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
2475 * modules/gnu.c, modules/m4.c: Use M4ARG.
2477 2001-10-01 Akim Demaille <akim@epita.fr>
2479 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
2480 (m4_regexp_compile): New.
2481 (regexp, patsubst): Use it.
2483 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2485 Reinstate the memory handling improvements from the patch I just
2486 reverted. Relevant ChangeLog entries repeated here:
2488 * m4/module.c (m4_module_remove): New function that holds the core
2489 of the old m4_module_unload.
2490 (m4_module_unload): Use it.
2491 (m4_module_unload_all): When we know the modules will never be
2492 used again (i.e. on exit), free up as much module memory as
2493 possible. There are still some artifacts from resident modules
2494 living inside ltdl.c, but everything else is freed.
2495 * m4/debug.c (m4_debug_exit): Free memory allocated in
2497 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
2498 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
2499 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
2500 * m4/m4module.h: Updated prototypes.
2501 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
2502 * m4/hash.h: Updated prototypes.
2503 * src/main.c (main): Use all these new functions to clean up as
2504 much memory as possible before exit.
2506 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2508 Reverted my large patch for removing the old m4_symbol
2509 structure on 2001-09-20. We are still not happy about the way
2510 trace works in conjunction with defn and undefine, and leaving
2511 the reverted patch active prevents us from moving the traced
2512 bit from the definition back to the symbol.
2514 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2516 * configure.in: Moved to...
2517 * configure.ac: ...here. Added a libtool like timestamped
2518 banner, and tidied up the libltdl cruft.
2519 * config/mkstamp: Script to extract a timestamp from ChangeLog.
2520 * modules/Makefile.am (INCLTDL): Removed. This is required
2521 only when libltdl is configured in a subdirectory.
2522 * src/Makefile.am: Ditto.
2523 (LIBADD_DL): No need to add this again, libtool already knows
2524 that libm4.la depends on it.
2525 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
2528 * TODO: stackovf.c is basically broken.
2529 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
2531 2001-09-28 Akim Demaille <akim@epita.fr>
2533 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
2535 2001-09-27 Akim Demaille <akim@epita.fr>
2537 * tests/m4.in: Don't use short options.
2538 Simplify the stderr signature normalization.
2540 2001-09-27 Akim Demaille <akim@epita.fr>
2542 tests/m4 shall be position independent.
2546 * tests/testsuite.at: No args to AT_INIT.
2547 * configure.in, tests/Makefile.am: Adjust.
2549 2001-09-22 Akim Demaille <akim@epita.fr>
2551 Autotest has changed again.
2553 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
2554 (package.m4): Remove.
2555 * configure.in: Adjust to LIBADD_GMP.
2557 2001-09-21 Gary V. Vaughan <gary@gnu.org>
2559 * config/gmp.m4 (AC_ARG_WITH): Removed.
2560 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
2561 (AC_LIB_GMP): When performing a test compile against libgmp,
2562 include the header gmp.h if possible, and link against -lgmp. If
2563 they both work define USE_GMP.
2564 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
2565 (mpeval_LTX_init_func): Complain on load that there was no libgmp
2568 2001-09-20 Gary V. Vaughan <gary@gnu.org>
2570 * m4/evalparse.c: Moved to...
2571 * modules/evalparse.c: ...here. This code is shared between
2572 modules/mpeval.c and modules/m4.c, so there is no need to pollute
2573 the libm4 API with its details. Moderately rewritten to interface
2574 into its clients more simply.
2575 * m4/eval.c: Deleted. Migrated functionality to...
2576 * modules/m4.c: ...here.
2577 (builtin_eval): Implemented in terms of the new interface style.
2578 * modules/mpeval.c (builtin_mpeval): Ditto.
2579 * m4/m4module.h: Removed references to the former m4/eval.c.
2580 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
2581 (EXTRA_libm4_la_SOURCES): Deleted.
2582 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
2583 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
2585 2001-09-20 Akim Demaille <akim@epita.fr>
2587 * config/gmp.m4 (AM_WITH_GMP): Rename as...
2589 By default, use gmp.
2591 * configure.in: Adjust.
2592 Use Automake conditionals for USE_GMP.
2593 Always compute sizeof (long long int).
2594 This was a bug BTW, as `eval' (not `mpeval') depends on it:
2595 before, it was used _only_ if mpeval was not activated.
2596 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
2597 (mpeval_la_LIBADD): New macros.
2598 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
2600 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
2601 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
2604 2001-09-20 Akim Demaille <akim@epita.fr>
2606 * tests/Makefile.am (package.m4): New.
2607 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
2609 2001-09-20 Gary V. Vaughan <gary@gnu.org>
2611 More cleanup. After the last patch, m4_symbol holds nothing but
2612 the head of a chain of m4_token_data. So I have removed the old
2613 m4_symbol, so that m4_token_data chains are stored directly in the
2614 value cell of a hash table node. But there's more... m4_symbol
2615 was a more natural name for the symbol value cell, and now that it
2616 is gone I have renamed the former m4_token_data structure to
2617 m4_symbol. This change turned out to be a pig to get right, since
2618 the original code didn't need to modify the value cell itself,
2619 since changing the chain happened inside the m4_symbol that used
2620 to be returned -- I had to pass the address of the value cell
2621 across various function calls, incase the head value changed. I
2622 also tightened up the memory management to help me find a nasty
2623 memory corruption bug that took me all night to track down...
2625 * m4/m4private.h (struct m4_symbol): Removed.
2626 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
2628 * m4/hash.c (m4_hash_iterator_value): Return the address of the
2629 value cell. Updated all callers.
2630 * m4/symtab.c: Took advantage of the simplification in the data
2631 structures to rewrite a lot of this file more simply. There is
2632 still some room for optimisation here, but we should tackle that
2633 systematically closer to the release.
2635 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
2636 revealed. This version is ahead of CVS libtool until I get chance
2637 to flush my changes.
2638 * m4/module.c (m4_module_remove): New function that holds the core
2639 of the old m4_module_unload.
2640 (m4_module_unload): Use it.
2641 (m4_module_unload_all): When we know the modules will never be
2642 used again (i.e. on exit), free up as much module memory as
2643 possible. There are still some artifacts from resident modules
2644 living inside ltdl.c, but everything else is freed.
2645 * m4/debug.c (m4_debug_exit): Free memory allocated in
2647 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
2648 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
2649 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
2650 * m4/m4module.h: Updated prototypes.
2651 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
2652 * m4/hash.h: Updated prototypes.
2653 * src/main.c (main): Use all these new functions to clean up as
2654 much memory as possible before exit.
2656 2001-09-18 Gary V. Vaughan <gary@gnu.org>
2658 The `traced' flag needs to be attached to the definition of a
2659 symbol rather than the current symbol containing the definition.
2660 Implementing this showed up some long standing post 1.4 bugs in
2661 flag propogation which I also fixed.
2663 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
2664 (struct m4_token_data): And add it back in here.
2665 * m4/input.c (init_macro_token): Propogate the traced flag
2667 * m4/macro.c (expand_argument): Ditto.
2668 * tests/builtins.at (trace2, trace3): New tests based on Akim's
2671 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2673 * m4/m4private.h (struct m4_token_data): Simplified by removing
2674 the redundant `traced' flag, and one level of structure nesting.
2675 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
2676 * m4/input.c (init_macro_token): No need to initialise removed
2678 * m4/macro.c (expand_argument): No need to copy it either.
2679 * m4/utility.c (m4_token_data_func_traced): Or provide an access
2682 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
2683 dependant on multiple symbols with the same key, so preserving
2684 relative symbol order in each bucket during resizing is no longer
2685 required. The resize function is considerably faster as a result.
2687 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
2688 s/m4_symbol_insert/m4_symbol_define/g;
2689 s/m4_builtin_insert/m4_builtin_define/g;
2690 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
2692 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2694 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
2695 commits, the m4_lookup_symbol dispatch function is split into
2696 specialised functions that must be called directly.
2698 * m4/m4module.h (m4_symbol_lookup_t): Removed.
2699 * m4/symtab.c (m4_lookup_symbol): Removed.
2700 (m4_symbol_builtin, m4_symbol_macro): New functions.
2701 * m4/builtin.c (m4_builtin_define): Split into...
2702 (m4_builtin_pushdef, m4_builtin_insert): ...these.
2703 (m4_macro_define): Split into...
2704 (m4_macro_pushdef, m4_macro_insert): ...these.
2705 * src/main.c (main): Set command line macros from `-D' parameters
2706 using `m4_macro_define'.
2708 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2710 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
2711 this from m4_remove_table_reference_symbols().
2712 * m4/m4module.h, m4/module.c: Updated all references.
2714 2001-09-07 Akim Demaille <akim@epita.fr>
2716 * modules/stdlib.c, modules/times.c: Misc cleanups.
2718 2001-09-07 Akim Demaille <akim@epita.fr>
2720 * configure.in: We now need Autoconf 2.52e.
2721 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
2722 and `M4_SYMBOL_DELETE'.
2723 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
2724 * src/main.c (main): Adjust.
2726 2001-09-06 Gary V. Vaughan <gary@gnu.org>
2728 Fix the obstack.h problem once and for all! At configure time we
2729 can test for a system supplied obstack.h: depending on the
2730 result, we now generate system.h with an #include of the correct
2731 header. As a bonus, I've also added a --with-included-obstack,
2732 incase the user doesn't like the system obstack for some
2733 reason... and also we can test the shipped obstack on a system
2734 that has oe of its own. We also now need to be careful to add
2735 build directories to the include search path, since the generated
2736 system.h will be in the build tree.
2738 * configure.in (AC_CONFIG_FILES): Generate system.h from
2740 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
2741 include the system obstack header or the copy shipped with M4.
2742 Allow the user to override configure and force the build to use
2743 the shipped version.
2744 * m4/system-h.in: New file, template for...
2745 * m4/system.h: ...this. Now deleted.
2746 * m4/m4module.h: Include system.h before everything else.
2747 * src/freeze.c: Ditto.
2748 * m4/Makefile.am (dist-hook): Remove generated system.h.
2749 (INCLUDES): Check builddir for generated headers before checking
2751 * modules/Makefile.am (INCLUDES): Ditto.
2752 * src/Makefile.am (INCLUDES): Ditto.
2754 2001-09-05 Gary V. Vaughan <gary@gnu.org>
2756 * TODO: Remove the items that have been addressed already.
2758 2001-09-05 Akim Demaille <akim@epita.fr>
2760 * src/main.c (main): Standardize --version.
2762 2001-09-05 Akim Demaille <akim@epita.fr>
2764 * modules/format.c (format): Have a bigger `str'.
2766 2001-09-05 Akim Demaille <akim@epita.fr>
2768 Rationalize warnings, reporting the macro name as if it were a
2769 program name, and assertions.
2771 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
2773 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
2775 Use assert for internal errors.
2776 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
2778 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
2780 * tests/builtins.at (pushpop): Adjust.
2782 2001-09-05 Akim Demaille <akim@epita.fr>
2784 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
2787 2001-09-05 Akim Demaille <akim@epita.fr>
2789 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
2790 * m4/macro.c, m4/symtab.c: Adjust.
2792 2001-09-05 Akim Demaille <akim@epita.fr>
2794 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
2795 (m4_symbol_pop, m4_symbol_del): this.
2796 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
2797 (m4_symbol_popdef, m4_symbol_delete): New.
2798 (m4_lookup_symbol): Adjust.
2799 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
2801 2001-09-05 Akim Demaille <akim@epita.fr>
2803 * m4/m4module.h (m4_symbol_lookup): Rename as...
2804 (m4_symbol_lookup_t): this.
2806 2001-09-05 Akim Demaille <akim@epita.fr>
2808 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
2810 * m4/symtab.c (m4_lookup_symbol): Adjust.
2812 2001-09-03 Gary V. Vaughan <gary@gnu.org>
2814 Bootstrap will now work with Libtool 1.4.1 or higher:
2815 * bootstrap: Remove stale autom4te.cache files when
2817 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
2819 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
2820 libtool.m4 directly.
2821 Run libtoolize to refresh ltmain.sh.
2822 * config/ltmain.sh: Deleted.
2823 * acinclude.m4: Deleted.
2824 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
2826 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
2827 implementation for the cvs impaired libtool user.
2829 2001-09-03 Akim Demaille <akim@epita.fr>
2831 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
2833 Avoid using `default' in switch, as it hides useful compiler
2834 warnings when a case is forgotten.
2836 2001-09-03 Akim Demaille <akim@epita.fr>
2838 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
2839 is no such thing as `WITH_MODULES'.
2841 2001-09-03 Akim Demaille <akim@epita.fr>
2843 Improve the test suite's selfcontainedness.
2845 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
2846 (Include, Undivert): Tag the other input files.
2847 * tests/generate.awk: Catch `@comment file:'.
2848 `-I $src' is no longer needed.
2849 `next' is really like `return': the rest is skipped.
2850 Adjust to `input.m4'.
2851 (fatal): New function.
2852 * tests/foo, tests/incl.m4: Remove.
2854 2001-09-01 Gary V. Vaughan <gary@gnu.org>
2856 The shadowing mechanism and, infact, the whole symbol table
2857 implementation was creaking under the weight of the features piled
2858 on top of it. We now have a separate hash table module which will
2859 dynamically resize to keep symbol density withing good performace
2860 limits, and a new symtab module layered above it. Symbol lookups
2861 are now marginally more efficient (since the shadowed flag is no
2862 longer required) and symbol removal, such as on module unload, is
2863 considerably faster due to a reorganisation of the data structures
2866 * src/main.c (main): Don't mention `-H'.
2867 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
2870 * m4/hash.c: New generalised dynamic hash table data structure
2872 * m4/hash.h: Public interface.
2873 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
2874 (libm4_la_SOURCES): Add hash.c.
2875 * m4/symtab.c: More or less rewritten from scratch, within the
2876 bounds of the previous API.
2877 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
2878 call. Updated all callers.
2879 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
2880 declarations to reflect API changes.
2881 (M4INIT): Generate a declaration too, to avoid the warning with
2882 --enable-debug builds.
2885 * m4/utility.c (hash_table_size): Removed.
2886 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
2887 names, which are then looked up by builtin_dumpdef() as necessary.
2888 This implies a small speedup in builtin_symbols(), which discarded
2889 all of the symbol info under the old call.
2890 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
2891 shadowing is implicit in respect to the new data structures.
2892 symbol names are no longer duplicated here, they are stored in the
2893 key field of the hash table.
2894 Moved macro_args and blind_no_args...
2895 (m4_token_data): ...to here.
2896 m4/macro.c (expand_macro): Added a name argument since the symbol
2897 name is no longer copied into each struct m4_symbol. Modified all
2899 (collect_arguments): Ditto.
2900 * modules/m4.c (set_trace): Ditto.
2901 * modules/gnu.c (builtin_symbols): Updated.
2902 * src/freeze.c (produce_symbol_dump): Much improved in light of
2903 the improved symbol table layout.
2905 2001-09-01 Gary V. Vaughan <gary@gnu.org>
2907 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
2909 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
2910 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
2911 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
2912 SYMBOL_HANDLE): Ditto.
2913 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
2914 modules/gnu.c, modules/m4.c, src/freeze.c,
2915 src/main.c: Updated all references.
2917 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
2918 Automake 1.5 chokes on dynamic source file lists, Besides, it is
2919 already listed in m4_LDADD... how did that ever used to work?
2920 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
2922 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
2923 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
2925 * tests/m4: Don't call the m4 wrapper script with libtool, it
2926 works fine all by itself.
2928 2001-08-30 Gary V. Vaughan <gary@gnu.org>
2930 The experimental `changeword' feature never took off, and has
2931 no obvious advantages over `changesyntax' to compensate the
2932 enormous speed penalty it carries:
2933 * configure.in (ENABLE_CHANGEWORD): Removed.
2934 * m4/m4module.h (m4_set_word_regexp): Removed.
2935 * m4/m4private.h (m4_token_data): Removed original_text field.
2936 * m4/utility.c (m4_token_data_orig_text): Removed.
2937 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
2938 * m4/macro.c: Ditto.
2939 * src/main.c: Ditto.
2940 * modules/Makefile.am (changeword.la): Removed.
2941 * modules/changeword.c: File removed.
2942 * doc/m4.texinfo: References to changeword and --word-regexp
2944 * po/POTFILES.in: modules/changeword.c removed.
2945 * tests/atlocal.in (ENABLE_CHANGEWORD): Removed.
2946 * tests/builtins.at (changeword): Test removed.
2948 2001-08-30 Akim Demaille <akim@epita.fr>
2950 * bootstrap.sh: Create aclocal.m4 instead of modifying it.
2951 This also help having a single list of m4 files: in
2953 * config/Makefile.am (STANDARD_MACROS): Rename as...
2954 (ACLOCAL_MACROS): this.
2955 (list-standard-macros): Remove.
2958 2001-08-29 Gary V. Vaughan <gary@gnu.org>
2960 In an attempt to moderate my egomania...
2961 * tests/modules.at: Remove attributions.
2963 * tests/generate.awk: When making substitutions to "@&t@", either
2964 "&" or "\&" in the substitution string argument to gsub refer back
2965 to the matched text. "@\\&t@" seems to work though, Tests 43 and
2968 2001-08-29 Akim Demaille <akim@epita.fr>
2970 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)
2971 (include, indir, multiquotes, patsubst, pushdef/popdef, regexp)
2972 (sync-lines, trace, translit, undivert, wrap): Move to...
2973 * tests/builtins.at: this new file.
2974 * tests/others.at (Discard comments, import-environment): Move to...
2975 * tests/options.at: this new file.
2977 2001-08-29 Akim Demaille <akim@epita.fr>
2979 * tests/others.at (Freezing modules)
2980 (--module-directory: absolute path, modpath2, modpath3)
2981 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
2982 * tests/modules.at: here, new file.
2983 * tests/others.at, tests/generate.awk: Add a banner.
2984 * tests/testsuite.at: Adjust.
2985 (AT_CHECK_M4_FILTER): New, but unused.
2987 2001-08-29 Akim Demaille <akim@epita.fr>
2989 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
2991 * tests/others.at (wrap): Inline wrap.m4.
2992 (shadow): Inline shadow.m4.
2993 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
2994 * tests/m4: Simplify.
2996 2001-08-29 Akim Demaille <akim@epita.fr>
2998 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
3001 2001-08-29 Akim Demaille <akim@epita.fr>
3003 * tests/generate.awk (normalize): s/@__@/@&t@/.
3005 2001-08-28 Akim Demaille <akim@epita.fr>
3007 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.
3009 2001-08-28 Gary V. Vaughan <gary@gnu.org>
3011 * bootstrap (generate.awk): Generate test cases with new script.
3013 2001-08-27 Akim Demaille <akim@epita.fr>
3015 * tests/Makefile.am (installcheck-local): Don't use
3016 `dc_install_base' which is not visible here, but `exec_prefix'
3017 which is clearly the RT anyway.
3018 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
3019 related to testing a now installed m4.
3020 * tests/m4: Do it here.
3022 2001-08-27 Akim Demaille <akim@epita.fr>
3024 * tests/others.at (indir): Formatting change.
3026 2001-08-27 Akim Demaille <akim@epita.fr>
3028 * tests/Makefile.am (installcheck-local): New.
3029 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
3031 Prefer options over envvars.
3032 * src/main.c (main): First bug caught by the test suite (yeah!):
3033 --batch lacked a `break' which resulted in an accidental
3034 invocation of --discard-comments.
3036 2001-08-27 Akim Demaille <akim@epita.fr>
3038 * tests/others.at (capitalize, changeword, comments, ddivert)
3039 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
3040 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
3041 (sysv-args, trace, translit, undivert): Don't rely on files in
3042 examples/: AT_DATA them.
3044 2001-08-27 Akim Demaille <akim@epita.fr>
3046 Let the test suite use a wrapper around the not installed m4 to
3047 pretend it is (installed).
3049 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
3050 such a way that m4 does not process them.
3051 * configure.in: The package name seems to be `m4', not `M4'.
3053 * tests/atlocal.in (at_package, M4): Remove.
3054 * tests/testsuite.at, tests/others.at: Use m4, not $M4.
3056 2001-08-27 Akim Demaille <akim@epita.fr>
3058 * tests/Makefile.am (CLEANFILES): Remove.
3059 (DISTCLEANFILES, clean-local): New.
3060 * examples/mktests.sh: Remove.
3062 2001-08-27 Akim Demaille <akim@epita.fr>
3064 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
3065 Don't use aclocal: it's written by hand.
3066 * aclocal.m4: m4_include all the files instead of being built by
3068 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
3069 until it reads the traces by itself.
3070 * configure.in: Require Autoconf 2.42c as we are now using
3071 AC_CONFIG_TESTDIR instead of AT_CONFIG.
3072 Catch unexpanded `jm_' macros.
3073 * config/atconfig.m4: Remove.
3074 * config/error.m4: new.
3075 * config/Makefile.am: Ship the files included by aclocal.m4.
3076 * tests/Makefile.am (TESTSUITE_SOURCES): Rename as...
3077 (TESTSUITE_AT): this, to please Automake.
3078 (TESTSUITE): This target uses autotest/autotest.m4, not
3079 autotest/general.m4.
3080 * tests/testsuite.at: Prereq Autotest 2.52c.
3081 * examples/Makefile.am (pkgdata_DATA): Rename as...

3084 (dist_man_mans): this.
3086 2001-08-20 Gary V. Vaughan <gary@gnu.org>
3088 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
3089 Robert Collins, building on Cygwin no longer requires Windows
3090 import and export symbol decorations.
3091 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.
3092 * m4/error.h (M4_SCOPE) [cygwin*]: Ditto.
3093 * m4/debug.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.

3099 * m4/xmalloc.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
3100 * configure.in (LIBM4_DLL_IMPORT) [cygwin*]: Don't set this
3102 * src/Makefile.am (AM_CPPFLAGS) [cygwin*]: Don't use it either!
3103 * modules/Makefile.am (AM_CPPFLAGS) [cygwin*]: Ditto.
3105 2001-08-20 Gary V. Vaughan <gary@gnu.org>
3107 Ansify the source. Previously we had a mix, where my code was
3108 in a K&R compatible style, and the preexisting code was in ANSI
3109 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
3110 and now the code base is much cleaner.
3112 * m4/system.h: Remove M4_PARAMS macro and all users. Remove
3113 VOID macro and all users.
3114 * m4/m4module.h: Ansify function prototypes and headers.
3115 * m4/builtin.c: Ditto.
3116 * m4/evalparse.c: Ditto.
3117 * m4/input.c: Ditto.
3118 * m4/macro.c: Ditto.
3119 * m4/module.c: Ditto.
3120 * m4/output.c: Ditto.
3122 * m4/symtab.c: Ditto.
3123 * m4/utility.c: Ditto.
3124 * modules/format.c: Ditto.
3125 * modules/gnu.c: Ditto.
3126 * modules/m4.c: Ditto.
3127 * modules/mpeval.c: Ditto.
3128 * src/freeze.c: Ditto.
3130 * src/main.c: Ditto.
3132 2001-08-20 Akim Demaille <akim@epita.fr>
3134 * config/atconfig.m4: s/EOF/ATEOF/, so that configure can be
3135 generated with stock 2.52.
3137 2001-08-20 Akim Demaille <akim@epita.fr>
3139 * config/atconfig.m4: New, until part of Autoconf per se.
3140 * configure.in (AT_CONFIG): Use it.
3142 * tests/mkconfig.sh, tests/atconfig.in, tests/defs: Remove.
3143 * tests/atlocal.in: New.
3144 * tests/generate.awk: For the time being, the empty quadrigraph is
3146 * tests/others.at (changeword, gmp): Check the configuration
3147 variable against `yes'.
3148 * tests/testsuite.at (dnl): Allow it, as it's used all over the
3151 2001-08-20 Akim Demaille <akim@epita.fr>
3153 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
3154 * modules/m4.c (undivert): Disable the possibility of undiverting
3155 several files at once: it is not documented, it is inconsistent
3156 with the other macros, it can be straightforwardly mocked by
3157 several invocations, and most importantly, it prevents the
3158 possibility of other kinds of extension.
3159 Use `m4_numeric_arg'.
3161 2001-08-20 Akim Demaille <akim@epita.fr>
3163 * examples/include.m4: Typo.
3164 * tests/generate.awk: Really add it.
3165 * tests/Makefile.am: Adjust.
3166 * tests/others.at (Discard comments): It sure fails without `-c'.
3167 (include, undivert): Add -I examples/.
3169 2001-08-20 Akim Demaille <akim@epita.fr>
3171 Use sprintf, not ecft and friends since it is standard, portable,

3382 (M4FINISH_HANDLER): And similarly for finish functions.
3383 * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER
3384 -- Add indirection to the CONC macro so that arguments are
3386 * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
3387 * modules/shadow.c (m4_init_module): Ditto.

3399 instead of the old module argument.
3400 (m4_builtin_table_install): Ditto.
3401 * modules/load.c (m4_resident_module): Removed. This is no
3402 longer implemented as a magic symbol...

3420 various tokens that are passed between functions.
3421 (struct m4_symbol): Removed the module field. The
3422 module association does not belong with the symbol...
3423 * m4/input.c (struct m4_builtin): ...it belongs with the builtin
3424 that the module implementation code is from. Added a handle
3426 (m4_push_macro): Add a `handle' argument. Changed all callers.
3427 (init_macro_token): Set the `handle' field for the
3429 * m4/macro.c (expand_argument): Copy the new handle field during
3431 * modules/m4.c (macro_install): Use the new handle field to
3432 optimise the search for the correct builtin structure, and pass
3433 the handle details to m4_builtin_define.
3435 2001-08-15 Akim Demaille <akim@epita.fr>
3437 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Be sure `m4/' exists
3438 when creating `m4/obstack.h'.
3439 * tests/Makefile.am (TESTS_ENVIRONMENT): Pass top_srcdir and
3441 * tests/defs: Make them absolute.
3442 (CDPATH) Neutralize.
3443 * tests/gethem: Use them.
3445 2001-08-14 Gary V. Vaughan <gary@gnu.org>
3447 * config/ltmain.sh: Doh! Import again for a quoting fix that
3448 prevented any regression test from passing.
3450 * m4/m4module.h (obstack.h): Choose between installed version
3451 and shipped version based on configure tests.

3458 them to AC_INIT and AM_INIT_AUTOMAKE.
3459 * Makefile.am (AUTOMAKE_OPTIONS): Remove `gnits' which would
3460 disallow MY_NAME and MY_VERSION arguments to AM_INIT_AUTOMAKE.

3462 shell variable m4_cv_func_obstack_h.
3463 * tests/defs (M4): Be more careful about relative path to libtool
3464 script and m4 binary by using $srcdir.
3466 * src/main.c (main): Use lt_dlinsertsearchdir to prepend -M
3467 optargs to the existing libltdl search path.
3468 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.

3476 interactive mode off.

3507 * doc/m4.texinfo (Include): Add missing blank.

3527 2001-04-08 Roderick Koehle <Roderick.Koehle@infineon.com>
3529 * modules/format.c (format): Formatting for %f was not
3530 interpreting the position of the decimal point correctly for
3533 2000-12-01 Gary V. Vaughan <gary@gnu.org>
3535 * TODO: Removed m4exit bug.

3539 feature to mark modules as resident if they export
3540 `m4_resident_module' as TRUE.
3541 (m4_module_unload): Do not remove resident modules, and take care
3542 with symbol insertion and deletion with resident modules.
3543 * m4/ltdl.c, m4/ltdl.h: Update to latest unreleased versions to
3544 use resident modules feature.
3546 2000-11-30 Gary V. Vaughan <gary@gnu.org>

3607 Move the implementation of GMP support for the mpeval() builtin
3608 into a loadable module that depends on libgmp. mpeval() and
3609 eval() share a common parser, now in m4/evalparser.c; the code
3610 in m4/numb.c and m4/numb.h is now physically split between
3611 m4/eval.c (the eval() backend) and modules/mpeval.c (the
3612 mpeval() backend), rather than being differentiated by cpp
3613 macros and multiple inclusion. The mpeval module is always
3614 built but will generate an diagnostic if it is used from an
3615 installation that didn't link in the gmp library.
3616 * modules/Makefile.am: build and install the new mpeval module.
3617 * modules/mpeval.c: Now contains the former parts of m4/numb.c
3618 and m4/numb.h that are required for gmp support in mpeval().
3619 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
3620 * m4/evalmp.c: Removed.
3621 * m4/m4module.h: Removed conditional prototype for
3623 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
3624 and m4/numb.h that do not rely on gmp.
3625 * m4/evalparse.c: New file, contains the shared parts of the
3626 eval() and evalmp() parser implementations, and is no longer
3627 unencumbered by cpp magic to uncover the right parts.
3628 * m4/numb.h: Removed. It's former contents are split between
3629 m4/eval.c and modules/mpeval.c.
3632 * tests/other-tests/changeword.test: New test. Rudimentary
3633 testing of changeword builtin runs only if --wnable-changeword
3634 was used at configure time.
3635 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
3636 alternation correctly. Split into two expressions to compensate.
3637 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
3638 * modules/Makefile.am: Build changeword module.
3639 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
3640 only when --enable-changeword was passed to configure.
3641 (builtin_changeword): If --enable-changeword was not used, then
3642 report that changeword() builtin has no support in m4 binary.
3644 2000-11-28 Gary V. Vaughan <gary@gnu.org>
3646 * src/main.c (main): Fixed a particularly nasty bug is
3647 user_search_path setting -- the -M flag processing must be
3648 extremely careful with search path ordering, or else the default
3649 installed module directory (possibly containing modules from a
3650 previous release) is placed earlier in the search path than any -M
3651 arguments (which are relied upon to load uninstalled modules with
3652 most of the tests in the regresion suite).
3654 * modules/load.c (builtin_load): Nasty hack to prevent adding
3655 symbols to symtab again if a module is loaded more than once.
3656 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
3658 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
3659 possible NULL pointer dereference.
3661 * m4/module.c (m4_module_find_by_modname): Renamed from
3662 m4_module_modname_find. Fixed all references.
3663 (m4_module_find_by_builtin): New function.
3665 * modules/modfreeze.test: load the `load' module with each
3667 * src/freeze.c (produce_frozen_state): Simplified in light of
3668 module field in m4_symbol. Allow a third argument for text macros
3669 to name the originating module.
3670 (reload_frozen_state): ditto.
3671 * m4/m4module.h: Fixup prototypes.
3672 * m4/builtin.h (m4_builtin_define): Add a module argument so
3673 that symbols can be registered against the defining module.
3674 (m4_macro_define): ditto.
3675 * m4/m4private.h (m4_symbol): Make the module field const to save
3676 on casting in the rest of the code.
3677 (SYMBOL_MODULE): New macro.
3679 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
3680 symbol reference maintenance bugs when removing a symbol from the
3683 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
3685 2000-11-27 Gary V. Vaughan <gary@gnu.org>
3687 * configure.in (m4_cv_func_obstack): A better check for whether
3688 libc has an obstack implementation.
3689 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
3691 * configure.in (--with-modules): Changed semantics. This
3692 option is now used to list modules to be preopened.
3693 * src/m4.h: #include "ltdl.h" unconditionally.
3694 * src/main.c: Removed all dependencies on WITH_MODULES.
3695 * src/freeze.c: ditto.
3696 * modules/Makefile.am: ditto.
3697 * m4/m4.c (builtin_m4exit): ditto.
3698 * modules/modpath1.test: ditto.
3699 * modules/modpath2.test: ditto.
3700 * modules/modpath3.test: ditto.

3703 * modules/shadow.test: ditto.
3704 * modules/unload.test: ditto.
3706 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
3707 comes up on demand in LTLIBOBJS now.
3708 * configure.in (getopt_long): Creating and relying on a link for
3709 getopt.h on hosts with no getopt_long() of thier own works
3710 correctly now. This is necessary so that callers of getopt_long()
3711 can simply `#include <getopt.h>': the naive way of doing this
3712 would end up using our own getopt.h and the installed
3713 getopt_long(), which is asking for trouble!
3714 (obstack_init): A similar argument applies to obstack.h and
3717 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
3718 On Solaris-2.5 (at least) the native dlopen implementation
3719 gets confused about m4.o when looking for module "m4". This
3720 version always looks for .la an .$lib_ext suffixed names first
3721 to work around the problem. Sigh.
3723 * po/POTFILES.in: Take account of these file movements.
3724 * src/Makefile.am (m4_SOURCES): removed eval.c.
3725 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
3726 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
3727 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
3728 * modules/m4.c (builtin_eval): Use m4_evaluate().
3729 * m4/eval.c: Moved here from src/eval.c to facilitate
3730 implementation of eval() builtin as part of the `m4' loadable
3732 (m4_evaluate): renamed from evaluate for namespace cleanliness.
3733 * m4/numb.c: Moved here from src/numb.c, since it is #included
3734 into eval.c at compile time.
3735 * m4/m4module.h (m4_evaluate): Added prototype.
3736 * src/m4.h (evaluate): Removed prototype.
3738 2000-11-25 Gary V. Vaughan <gary@gnu.org>
3740 * modules/perl.c (builtin_perleval): Use PL_na for
3741 compatibility with perl-5.6.
3743 * src/main.c (main): It is now safe to
3744 ``m4_module_install("m4")'', without tripping over the m4
3746 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
3747 versions having fixed the insidious module search order bug.
3749 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
3750 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
3752 * configure.in: Figure out whether to use the installed
3753 getopt.h or the supplied one.
3754 * src/Makefile.am: ditto.
3756 * po/POTFILES.in: List files in their new positions.
3758 * config/ltmain.sh: This needs to be checked in to match the
3759 libtool macros copied to acinclude.m4 (until a released
3760 libtool copes with m4's needs).
3761 * bootstrap: Run gettextize.
3763 2000-11-24 Gary V. Vaughan <gary@gnu.org>
3765 * AUTHORS: Added my details.
3768 * bootstrap: temporary update until released libtool catches up.
3770 * All files: Use new GNU GPL copyright blurb with current contact

3804 * modules/gnu.c: New file implementing a new loadable module wuth
3805 definitions for all the gnu extension builtins.
3806 * modules/format.c: Moved here from src/format.c. Now included
3809 * src/main.c (main): Load the traditional module if m4 was
3810 started in `no_gnu_extensions' mode.
3811 * modules/traditional.c: New file implementing the ``unix'' macro,
3812 required when m4 is executed in traditional mode, as a loadable

3825 the migration of all builtin implementations to loadable modules.
3826 * m4/macro.c: Moved this file here from the src directory,
3827 renaming all exported symbols to use the prefix ``m4_''.

3830 * m4/symtab.c: ditto.
3831 * m4/debug.c: ditto.

3833 * m4/output.c: ditto.
3835 * m4/ltdl.h, m4/ltdl.c: ditto.
3836 * m4/utility.c: Odd functions moved here from files in the src
3837 directory to facilitate builtin migration.
3839 2000-08-12 Gary V. Vaughan <gary@gnu.org>
3841 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
3842 error message, to make translators' jobs a little easier.
3843 (builtin_builtin): ditto.
3844 (builtin_traceon): ditto.
3845 (builtin_traceoff): ditto.
3846 Reported by Akim Demaille <akim@epita.fr>

3849 pkgincludedir instead.

3872 makeinfo calculates them for us, and to make any future
3873 reorganisation easier.
3874 (Frozen files): Document format version 2.
3875 `V' now takes argument `2'.

4015 * src/m4.c (main): Assume interactive mode if STDIN is connected

4018 initialised from here when loading a frozen file.
4020 * src/builtin.c: Much improved macro definition style.
4021 * src/m4private.h: Internal structures for m4_builtin and

4093 src dir and immediately after libm4 is built for confidence that
4094 it doesn't rely on the src directory.

4096 makeinfo stop the build on cygwin (because they don't work).
4098 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
4100 * m4/m4private.h: ...is not a public header, so moved to src.

4144 From Akim Demaille <akim@epita.fr>
4146 2000-01-17 Gary V. Vaughan <gary@gnu.org>
4148 * src/ltdl.c: Use access() to abort doomed module load attempts
4149 if module file does not exist.
4151 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
4152 getopt1.o will already be used if appropriate, so I moved getopt.c
4153 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
4155 * modules/modpath1.test: Use correct filename in header line.
4156 * modules/modpath2.test: ditto.
4157 * modules/modpath3.test: ditto.
4158 * modules/modpath4.test: ditto.
4160 Without these changes lt_dlopen("test") attempts to
4161 LoadLibrary("/bin/test") on Windows, which although harmless
4162 generates a spurious error message which spoils most of the tests:
4163 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
4164 (TESTS): s/test.test /modtest.test /
4165 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /
4166 (test_la_SOURCES, test_la_LDFLAGS): renamed to use modtest.
4167 * modules/modpath1.test: s/test.m4 /modtest.m4 /
4168 * modules/modpath2.test: ditto.
4169 * modules/modpath4.test: ditto.
4170 * modules/modpath3.test: s/-m test /-m modtest /
4171 * modules/shadow.m4: use {un,}loadmodule(`modtest').
4173 2000-01-16 Gary V. Vaughan <gary@gnu.org>
4175 * src/ltdl.c (find_file): Updated to new version with fixed memory
4176 allocation bug in `next'.

4179 * modules/Makefile.am: Cleaned up and reordered.
4181 2000-01-16 René Seindal <rene@seindal.dk>
4183 * modules/Makefile.am (TESTS): New tests for the module system.
4185 * modules/*.test: New files.
4187 * src/m4.c (main): Added call to module_init().
4188 Treats -M and -m as the arguments -D -U and -t, ie deferred.
4190 * src/m4.h: Added declaration of module_init().
4192 * src/module.c (module_init): No longer static
4194 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
4195 Added to shut up automake about non standard libtool library
4198 * src/module.c: Disabled DEBUG by default.
4200 * modules/README: Changed example from unload.m4 to shadow.m4
4202 * modules/shadow.m4: Renamed from unload.m4
4204 * modules/Makefile.am (EXTRA_DIST): Removed unload.m4.
4206 * src/m4.c (main): Functionality for -m and -M were reversed.
4209 2000-01-12 Gary V. Vaughan <gary@gnu.org>
4211 * doc/help2man.pl: updated to version 1.020.
4213 * lib/COPYING.LIB: updated to version 2.1.
4215 * lib/m4module.h: restructure the M4_SCOPE code to work when
4216 creating a dll which links with libm4.la and both DLL_EXPORT
4217 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
4220 2000-01-11 Gary V. Vaughan <gary@gnu.org>
4222 Merged the following changes from my tree:
4224 1999-06-15 Gary V. Vaughan <gary@gnu.org>
4226 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
4227 ported to compile shared libs.
4229 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
4230 use `__declspec(dllimport)' when linking libm4.la on win32.
4231 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
4233 * configure.in (M4OBJS): Discover whether we need the shipped
4234 implementation of getopt_long.
4235 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
4236 main binary here, as opposed to the module library in lib/libm4.la.
4238 1999-06-14 Gary V. Vaughan <gary@gnu.org>
4240 * modules/README: Updated to describe the improved libltdl based
4242 * README (cygwin): Added some compilation notes for building m4
4243 correctly under cygwin.
4244 * TODO: Cleaned out the entries for the module system since they
4245 are now implemented.
4247 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
4248 all instances of __P with M4_PARAMS.
4250 * lib/getdate.h: removed unreferenced file.
4252 * lib/m4private.h: New file to define the private interface to the
4253 token_data struct, which must be shared between m4module.c, and
4254 builtin.c but not exported to modules built from the installed
4255 m4module.h since it's size changes depending on compile time
4258 * src/m4.h: Lots of stuff moved to lib/m4module.h.
4260 * lib/m4module.h: New file to define the interface available when
4261 compiling m4 modules.
4262 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
4263 necessary for module compilation into this new file.
4265 * lib/Makefile.am (include_HEADERS): install headers (renamed to
4266 avoid nameclash with other system headers) necessary for compiling
4268 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
4269 so that modules can include the (renamed) installed headers and
4270 be guaranteed a matching implementation.
4271 * lib/m4error.h: renamed from error.h.
4272 * lib/m4obstack.h: renamed from obstack.h.
4273 * lib/m4regex.h: renamed from regex.h.
4274 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
4275 implementation, simply include the shipped version
4276 unconditionally, otherwise it is hard for a module to know
4277 whether the m4obstack.h header it is using matches the
4278 implementation it ends up linking against.
4279 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
4282 1999-05-18 Gary V. Vaughan <gary@gnu.org>
4284 * examples/misc.test: Don't run this test on machines which don't
4285 have a root user in /etc/passwd (e.g. cygwin).
4287 * tests/get-them (/^@example$/): Error messages might have a
4288 ``.exe'' suffix to the program name, or else use the libtool
4289 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
4290 of these cases are now catered for when comparing error messages
4292 * tests/other-tests/*.test: ditto.
4293 * examples/*.test: ditto.
4295 * tests/defs (M4): use libtool execute mode.
4296 * examples/defs (M4): ditto.
4298 * tests/get-them (END): explicitly close any open file.
4299 (printthem): In a regular expression, '{' is the start of a repeat
4300 count! Use `[{]' for a literal open brace.
4301 (/^@node /): Don't use substr on a string shorter than the trim
4304 1999-05-17 Gary V. Vaughan <gary@gnu.org>
4306 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
4308 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
4310 2000-01-10 Andreas Schwab <schwab@suse.de>
4312 * tests/other-tests/gmp.test: Find config.sh in build directory.
4314 * configure.in: Find tests/mkconfig.sh in $srcdir.
4316 * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in
4317 <signal.h> (for SUS2 compliant systems).
4319 * src/stackovf.c: Check for HAVE_SIGINFO_T in addition to
4322 2000-01-10 René Seindal <rene@seindal.dk>
4326 * TODO, NEWS: Cleaned up and updated.
4328 * src/m4.c (main): New variable exit_status for exit status in
4329 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
4330 file cannot be read instead of EXIT_SUCCESS.
4332 * src/builtin.c (m4_indir): Changed error message to help
4333 translators (from Akim Demaille <demaille@inf.enst.fr>).
4335 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
4338 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
4341 * src/input.c (match_input): Reordering of code, to avoid multiple
4342 calls to push_string_init() from obstack_grow(), which can happen
4343 with some compilers (found and fixed by James Bonfield
4344 <jkb@mrc-lmb.cam.ac.uk>).
4346 * src/stackovf.c: Added prototypes for ultrix.
4347 (setup_stackovf_trap): Added __P to cast.
4348 (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>)
4350 2000-01-09 René Seindal <rene@seindal.dk>
4352 * doc/m4.texinfo (Changequote): Added comment about changing
4353 quotes when the old quote is a part of the new.
4355 * src/builtin.c (expand_ranges): Added break after trailing dash.
4356 This caused misbehavious on some systems (found and fixed by Akim
4357 Demaille <demaille@inf.enst.fr>).
4359 * AUTHORS: Thomas Tanner included
4361 * acconfig.h: Added entry for ss_sp (see below).
4363 * configure.in (use_stackovf): Added check for stack_t with member
4364 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert
4365 <eggert@twinsun.com>).
4367 * doc/m4.texinfo (Frozen files): Added a simpler example for
4368 generating frozen files from several input files.
4370 1999-11-14 Paul Eggert <eggert@twinsun.com>
4372 * po/POTFILES.in: Add lib/getopt.c, lib/obstack.c,
4373 lib/regex.c, lib/xmalloc.c.
4375 1999-11-10 René Seindal <rene@seindal.dk>
4377 * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal.
4379 * src/module.c: reindented.
4380 (module_load): return if this is a repeated load of same module.
4381 (module_init): slight change of logic to avoid repeated
4382 initialisation debug messages.
4384 * Makefile.am (DIST_SUBDIRS): Added to ensure modules/ is included
4385 in the distribution.
4387 * modules/Makefile.am (test_la_LDFLAGS): set to -module to silence
4388 automake warnings about missing lib prefix.
4389 (time_la_LDFLAGS): ditto
4390 (stdlib_la_LDFLAGS): ditto
4392 1999-11-10 Paul Eggert <eggert@twinsun.com>
4394 * src/m4.h: Include error.h, since our macros use error.
4395 * src/m4.c: Don't need to include error.h.
4397 1999-11-09 Paul Eggert <eggert@twinsun.com>
4399 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
4400 and zero, as Solaris 7 cc does.
4401 (bcopy): Remove macro; no longer needed with new obstack.h.
4403 * src/output.c (freeze_diversions): Don't assume that a
4404 diversion size can fit in `int'. Check for diversion file
4405 size too large to be printed with `unsigned long'.
4407 * src/Makefile.am (CFLAGS): Omit -Wall.
4409 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.
4411 * src/debug.c (trace_format):

4417 1999-10-13 René Seindal <rene@seindal.dk>
4419 * configure.in (ALL_LINGUAS): Added Greek translation (el).
4420 (ALL_LINGUAS): Added Czech translation (cs).
4422 1999-03-30 Gary V. Vaughan <gary@gnu.org>
4424 * src/builtin.c: moved module loading functions into...
4425 * src/module.c: entirely new implementation using libltdl.
4426 * po/POTFILES.in: added src/module.c.
4427 * modules/Makefile.am (LTLIBRARIES): Removed lib prefix as these
4428 are modules, not linktime libraries.
4429 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
4430 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
4431 avoidance on exported symbols.
4432 * modules/test.c (m4_macro_table, m4_init_module,
4433 m4_finish_module): ditto.
4434 * modules/time.c (m4_macro_table): ditto.
4436 * modules/time2.m4: new file which requires command line loading
4438 * src/m4.c (--load-module): dynamically load named runtime module
4439 into running executable before reading the source.
4440 (--module-directory): prepend a directory to the module search
4442 (module_init()): Do this the first time we load a module instead;
4443 if the module subsystem is broken normal m4 scripts can still run.
4444 * src/m4.h (install_builtin_table): is now exported.
4446 1999-03-26 Gary V. Vaughan <gary@gnu.org>
4448 * src/module.c: removed. No longer required.
4449 * po/POTFILES.in: removed src/module.c.
4451 * Makefile.am (MAINTAINERCLEANFILES): Remove all the files that
4452 the bootstrap script can recreate.
4453 * acm4/Makefile.am (MAINTAINERCLEANFILES): ditto.
4454 * doc/Makefile.am (MAINTAINERCLEANFILES): ditto.
4455 * examples/Makefile.am (MAINTAINERCLEANFILES): ditto.

4458 * modules/Makefile.am (MAINTAINERCLEANFILES): ditto.
4459 * src/Makefile.am (MAINTAINERCLEANFILES): ditto.
4460 * tests/Makefile.am (MAINTAINERCLEANFILES): ditto.
4462 * acinclude.m4: removed. `aclocal -I acm4' handles this much
4464 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
4465 * acm4/gettext.m4: removed. It causes a multiple definition vs.
4466 the installed gettext.m4 file when running aclocal.
4468 1999-03-25 Gary V. Vaughan <gary@gnu.org>
4470 * configure.in (AM_INIT_AUTOMAKE): bumped version number to
4471 distinguish this from the last prerelease.
4472 (AC_LIBLTDL_CONVENIENCE): build libltdl as a convenience library
4473 in its own subdirectory.
4475 * modules/Makefile.am (*_SOURCES): renamed to use libtool's "no
4476 lib prefix on a module" feature.
4477 (LDFLAGS): Added `-module -avoid-version' flags to build
4478 versionless module libraries.
4479 * src/builtin.c (m4_load_module): use libltdl.
4480 (module_unload_all): use libltdl.
4481 * src/m4.c (module_init): initialise module loading on demand for
4482 better diagnostics, and so that m4 will still work even if
4483 the module code is broken.
4484 * src/m4.h (module_init): removed. No longer relevant.
4485 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on
4486 exported symbols for compatibility with dlpreopening.
4487 * modules/test.c (m4_macro_table, m4_init_module,
4488 m4_finish_module): ditto.
4489 * modules/time.c (m4_macro_table): ditto.
4491 * bootstrap: New file. Runs all the autoutils in the right order
4492 after a fresh checkout, or a make maintainer-clean.
4494 1999-02-18 Akim Demaille <demaille@inf.enst.fr>
4496 * src/builtin.c (dump_symbols): New function, factoring common
4497 content of m4_dumpdef and m4_symbols.
4498 (m4_dumpdef): Use it.
4499 (m4_symbols): New function, implementing `symbols'. Use it.
4500 * doc/m4.texinfo: Fixed missing commas after @xref, so that the
4501 file compile with modern makeinfo.

4503 (direntry): Modernize.
4505 1998-12-11 René Seindal <rene@seindal.dk>
4507 * src/builtin.c (predefined_tab): New predefined macros
4508 __m4_changeword__, __m4_gmp__ and __m4_modules__ for testing for
4509 configure time options.
4511 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
4513 * src/module.c (module_try_load): Don't try to be clever and
4514 overwrite argument string. Instead allocate all constructed
4515 strings locally, since they can have arbitrary lengths. Make
4516 arguments pointers to const.
4517 (module_search): Simplify due to above change.
4519 1998-11-29 René Seindal <rene@seindal.dk>
4523 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): New tests.
4525 * tests/other-tests/import-environment.{m4,test}: New test.
4527 * tests/other-tests/discard-comments.{m4,test}: New test.
4529 * doc/m4.texinfo (Invoking m4): Updated for --discard-comments.
4531 * src/m4.c (main): New option -c --discard-comments.
4532 New global variable discard_comments.
4534 * src/m4.h (token_type): New TOKEN_NONE for tokens to be
4535 discarded, ie never returned from next_token().
4536 Added declaration of discard_comments.
4538 * src/input.c (next_token): Now loops until token type is not
4539 TOKEN_NONE. Comments are now given this type when comments should
4542 * doc/m4.texinfo (Invoking m4): Updated for --import-environment
4545 1998-11-28 René Seindal <rene@seindal.dk>
4547 * src/m4.c (main): New option --import-environment (no single
4550 * When configured with --with-gmp both the normal (fast) eval()
4551 and the gmp aware mpeval() are defined. To restore previous
4552 bahaviour use "define(`eval', defn(`mpeval'))".
4554 * tests/other-tests/gmp.m4: Changed to use mpeval().
4556 * src/evalmp.c: New file for compiling eval.c as gmp aware.
4557 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
4559 * src/eval.c: Now includes "numb.c" directly. Everything in this
4560 file must by static, except evaluate(), which is changed to
4561 mp_evaluate() if USE_GMP in force.
4563 * src/numb.c: Changed to be included by eval.c instead of being
4564 compiled separately. Everything is declared static.
4566 * src/numb.h: Removed declarations of functions, as numb.c is now
4569 * src/builtin.c: Declaration of m4_mpeval() added.
4570 Inserted `mpeval' in builtin table.
4571 (do_eval): New function with common code for m4_eval and m4_mpeval.
4572 (m4_mpeval): New function for gmp version of eval.
4574 * src/m4.h: Declaration of mp_evaluate().

4577 (EXTRA_m4_SOURCES): Now has numb.c and numb.h
4579 * src/m4.c (main): m4 --version also shows which options were used
4580 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
4582 1998-11-27 René Seindal <rene@seindal.dk>
4584 * Error messages now always print program name before input file
4585 name as specified by GNU coding standards. Reported by Akim
4586 Demaille <demaille@inf.enst.fr>.
4588 * doc/m4.texinfo (Include): Change due to changed error message
4592 * tests/get-them: Minor change to sed script due to changed error
4595 * src/m4.c (print_program_name): New func used to print program
4596 name, input file and line number in error (). Used as an
4597 error_print_progname handler.
4598 (reference_error): Removed.
4599 (main): Assigns error_print_progname.
4601 * src/m4.h (M4ERROR): Removed reference_error ().
4603 1998-11-25 René Seindal <rene@seindal.dk>
4605 * Updated to libtool 1.2b.
4607 * src/builtin.c (install_builtin_table): Added braces to avoid
4608 warning of ambiguous 'else'.
4610 * src/module.c: Inserted search path code from path.c modified to
4612 (module_init): Configured default path used only if M4MODPATH is
4614 (module_try_load): Now reads libMODULE.la as generated by libtool
4615 for actual module name.
4616 (module_load): Gives better error messages on failure.
4618 * src/m4.h: Added declarations of structures and functions for
4619 generic search path handling.
4621 * src/path.c: Removed all module specific code and introduced new
4622 functions of more generic search path handling.
4624 1998-11-24 René Seindal <rene@seindal.dk>
4626 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
4627 included gettext, as <libintl.h> might not be found
4628 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
4630 1998-11-22 René Seindal <rene@seindal.dk>
4632 * src/output.c (insert_diversion): Fixed bug that might cause m4
4633 to read from standard output! Triggered by input
4634 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
4635 so now 'undivert(0)' does nothing.
4637 1998-11-18 René Seindal <rene@seindal.dk>
4641 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
4642 could be changed when compiling a illegal regexp, causing later
4643 use of the regexp to dump core.
4645 * src/module.c (module_load): Changed error message to conform to
4648 * src/m4.c (usage): Added message about reporting bugs.
4650 * doc/m4.texinfo (Changeword): Corrected a wrong example.
4651 (Changeword): Added note about the type of regexps used.
4653 * ltconfig, ltmain.sh: New files from Libtool 1.2.
4655 * configure.in: Added calls to AM_ENABLE_SHARED, AM_DISABLE_STATIC
4656 and AM_PROG_LIBTOOL.
4658 * acm4/modules.m4 (AM_WITH_MODULES): Redone completely to work
4661 * modules/Makefile.am: Changed completely to compile modules using
4662 libtool. The modules are compiled as shared libraries, and are
4663 renamed when installed.
4665 * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
4666 USE_SHL_LOAD to HAVE_SHL_LOAD
4668 * src/builtin.c (shipout_string): Now tests for a NULL string.
4670 * src/module.c: New level of indirection around non-portable
4671 functions to load shared objects. Intended to encapsulate the non
4672 portable parts better and to reduce the number of #ifdefs in the
4675 * Makefile.am (DIST_SUBDIRS): Instead of EXTRA_DIST for added
4676 directory modules/ to the distribution.
4678 1998-11-15 René Seindal <rene@seindal.dk>
4682 * modules/stdlib.c: New module `stdlib' defining some standard
4683 functions: getcwd, getlogin, getpid, getppid, getuid, getpwnam,
4684 getpwuid, hostname, rand, srand, getenv, setenv, unsetenv, uname.
4686 * src/builtin.c (shipout_string): New convenience function for
4687 builtins and modules.
4689 * src/module.c (module_load): Tentative support for
4690 shl_load/shl_findsym, but I cannot test it. Copied from MetaHTML.
4692 * Makefile.am (SUBDIRS): Directory modules added if configured.
4694 * modules/Makefile.am: Now correctly compiles and installs
4695 modules in pkglibexecdir.
4697 * src/m4.h: WITH_MODULES defined iff HAVE_DLOPEN or USE_SHL_LOAD.
4698 These two are now initialised by autoconf macros.
4700 * src/path.c (module_env_init): MODULE_PATH is always on the
4703 * src/Makefile.am: Now generated pathconf.h which defined the
4704 default MODULE_PATH.
4706 * configure.in (pkglibexecdir): Added defintion of pkglibexecdir,
4707 where modules are installed.
4709 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
4710 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
4711 build and install automatically, and it is prepared for other
4712 interfacec than dlopen().

4795 1998-10-07 René Seindal <rene@seindal.dk>
4799 * tests/Makefile.am (GENERATED_TESTS): Changed .m4 extension to
4800 .test, as the files are no longer just m4 input.
4802 * tests/get-them (FILE): Changed .m4 extension to .test.
4804 * src/m4.h (token_type): New token type TOKEN_SPACE introduced.
4805 Otherwise quoted strings with leading whitespace first in a macro

4808 * src/macro.c (expand_token): Handles new token type TOKEN_SPACE.
4809 (expand_argument): Do.
4811 * src/input.c (next_token): SPACE and NUM/OTHER characters are only

4839 * src/builtin.h: New file, declares some functions from builtin.c
4840 that are of use for other modules (shipout_int, numeric_arg,
4841 skip_space, bad_argc), and the macros ARG() and DECLARE().
4843 * src/builtin.c (install_builtin_table): New function. Each
4844 module brings in a builtin_table, which is pushed on a stack.
4845 (struct builtin_table): New struct for list of builtin_tables.
4846 (m4_loadmodule): New function to implement builtin "loadmodule".
4847 (shipout_int): No longer static, to be used by modules.

4868 * configure.in: Added modules/Makefile to AC_OUTPUT.
4870 * configure.in: Added code to implement --with-modules. Tests for
4873 * acconfig.h: Added WITH_MODULES
4875 1998-10-02 René Seindal <rene@seindal.dk>
4877 * examples/Makefile.am (pkgdata_DATA): Removed special target for
4878 check and variables TESTS. These tests are now run from the
4881 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
4882 directory. The files stay there but the tests are run from the
4885 * tests/Makefile.am (EXTRA_DIST): Added run-test.
4887 * tests/run-test: New file. Run a test manually
4889 * tests/Makefile.am, tests/get_them: Moved automatically generated
4890 tests (from the manual) to sub directory tests/gentest/. The
4891 tests/ directory had gotten a bit messy.
4893 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4895 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\
4896 wrap}.test: Added a few testcases.
4898 1998-08-21 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4902 * lib/Makefile.am (noinst_HEADERS): regex.h added
4904 * configure.in (jm_WITH_REGEX, jm_PREREQ_ERROR):
4905 acm4/{error,regex}.m4 (from fileutils-3.16u.tar.gz).
4907 * acm4/Makefile.am: created providing rules to create
4908 $(top_srcdir)/acinclude.m4 to be used by aclocal.
4910 * tests/defs (LANGUAGE, LC_ALL, LANG): force them to be
4911 `C'. Reported by Ulrich Drepper.
4913 * Makefile.am (SUBDIRS): Removed checks directory
4914 * configure.in (AC_OUTPUT): Removed checks/Makefile
4916 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
4917 the space when m4.texinfo is edited and whitespace.el is active.
4918 (Defn,example): idem.
4920 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4922 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
4923 ../COPYING. ../Makefile is a file which is certainly present when
4924 test is executed in testSubDir. One can't be sure that the COPYING
4925 file is in .. or ../.. in all situations, the ../Makefile is
4928 * doc/m4.texinfo (Include): adjusted expected test output
4929 according to new tests, i.e. the input will always come from the
4930 file `in' created by the test.
4932 * tests/Makefile.am: Added three lines at the top to get
4933 esyscmd.1.test working.
4935 * tests/get-them: modified to generate clearer tests who will need
4936 less maintenance when new test examples are created in
4937 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
4938 need the generic file `defs') shell scripts creating `in', `ok',
4939 `out' and when apropriate `okerr' and `err' in the directory
4940 `testSubDir' when executed. The compare of `ok' and `out'
4941 (and of `okerr' and `err') will be the exit status of the test.
4942 `out' must match `ok' (and `okerr' must match `err') for the test
4945 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
4946 the tests generated by tests/get-them getting it input normally
4947 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
4948 (dot) before the numeric part) is reserved for all other (hand
4949 written) tests. The `+' means one or more times.
4951 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4953 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
4954 supported short man page to refer to info documentation
4955 * helptoman.pl: added
4956 * configure.in: AC_PATH_PROG(PERL,perl)
4957 * Makefile.am (SUBDIRS): doc after src
4959 * libitized with libit 0.5 from

4981 "changesyntax" to modify the syntax table.
4983 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax
4984 table. All categories are assigned a syntax code and tokens are
4985 read according to this table.
4987 1998-08-09 René Seindal <rene@seindal.dk>
4989 * src/numb.{c,h}: New files, implements multiple precision eval
4990 using GNU gmp. Originally submitted by John Gerard Makecki
4991 (johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.
4993 * doc/m4.texinfo (Eval): Added documentation for multiple
4994 precision arithmetic library support.
4996 * src/m4.{c,h}, src/eval.c, src/builtin.c, configure.in: Changes
4997 to accommodate multiple precision eval.

5006 patch from Mike Howard <mike@clove.com>
5008 1998-08-06 René Seindal <rene@seindal.dk>
5010 * gettext.m4: corrected AM_WITH_NLS to handle use of installed

5017 * src/m4.h: Added ifdef ENABLE_NLS around include of <libintl.h>
5018 and _ macro. M4 now builds with --disable-nls.
5020 * src/m4.c (main): reintroduced textdomain(PACKAGE) to get gettext
5021 to look for right message catalogs. Call indef'ed by ENABLE_NLS.
5023 * configure.in (ALL_LINGUAS): Added complete list of translations:

5042 Used libitize (0.4) to update.
5044 * configure.in, ABOUT-NLS, intl/*, po/*: Added gettextize
5045 (0.10.25) support. Removed LOCALE, fr.msg, m4.cod and adjusted
5048 * src/stackovf.c: #ifdef USE_STACKOVF ... #endif to (de-)activate
5049 stack overflow functionality.

5069 src/stackovf.c: Rename _ to __P.
5070 * src/m4.h: Declare _ as a macro returning its argument, or else,
5071 include <libintl.h> and declare _ as gettext.

5128 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
5129 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler

5149 Remove the sed filter after ansi2knr for debug.c. Use $O instead
5150 of $U, put underline in extensions rather than in basenames. Use
5151 implicit rules, now that regularity makes this possible.
5152 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
5153 of ansi2knr whenever it is needed.
5154 * configure.in: Adjusted for correct STACKOVF substitution.
5155 * src/debug.c (trace_format): When not __STDC__, use (...) as a

5174 * {,/*}Makefile.in: Use && after all cd, in case they fail.
5176 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

5202 Reported by Jim Meyering.
5204 1994-09-23 François Pinard <pinard@iro.umontreal.ca>
5206 * src/stackovf.c: Declare the handler_t typedef earlier in the
5207 code, use it for stackovf_handler.
5208 (setup_stackovf_trap): Use RETSIGTYPE instead of void while
5209 casting sigsegv_handler.
5210 Reported by Robert Bernstein.
5212 * src/m4.c (main): Initialize program_name to argv[0] without

5236 * Makefile.in: Make TAGS in lib also, not just in src.
5237 Reported by Karl Berry.
5239 * Makefile.in (distclean, realclean): Instead of recursively
5240 calling $(MAKE) for the -local part, allow parallel execution of
5241 -recursive and -local, only delay the removal of config.status,
5242 which is repeated in both goals.
5244 1994-09-13 François Pinard <pinard@iro.umontreal.ca>
5248 * Makefile.in: Group all *clean-recursive goals in one, using sed
5249 to remove `-recursive' while calling make recursively. Also, use
5250 a subshell for each recursive $(MAKE).

5254 Reported by Kaveh R. Ghazi.
5256 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
5257 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
5260 * configure.in: Use date instead of touch for stamp-h.
5261 * Makefile.in (stamp-h.in): Idem.
5263 * Makefile.in (distclean, realclean): Force serial execution of

5279 * Makefile.in (MDEFINES): Remove INSTALL substitutions, for
5280 ./install.sh will not be correctly referred to in sub-Makefiles.
5281 Reported by John David Anglin.

5312 Reported by Jim Meyering.
5314 Solidify frozen files with respect to -P:
5315 * src/m4.c: Have -P set prefix_all_buitins variable instead of
5316 calling a function by that name. Declare the variable.
5317 * src/m4.h: Adjust declaration for prefix_all_buitins.
5318 * src/builtin.c (builtin_init): Merge in functionality from
5319 previous prefix_all_buitins function, while making entries in the
5320 symbol table, but not modifying the builtin description itself.
5322 * src/freeze.c (reload_frozen_state): Add a useless `break;',
5323 because *many* compilers do not accept an empty `default:'.

5337 functions, for implementing a global MAXIMUM_TOTAL_SIZE instead of
5338 a per buffer MAXIMUM_BUFFER_SIZE.
5340 * src/output.c (output_text): New function, for optimizing the
5341 output of strings of characters. Use it.
5343 1994-08-30 François Pinard <pinard@iro.umontreal.ca>

5348 * Makefile.in: Adjusted.
5349 * configure.in: Configure new Makefiles.
5351 * m4.h: Declare STRING typedef. Use it for comment and quote
5352 strings, adjusting all references. (This is the rudiments of a
5353 beginning for the eventual withdrawal of NUL terminated strings.)
5354 * output.c (shipout_text): Accept a length parameter, and use it.
5355 All callers adjusted.
5357 1994-08-29 François Pinard <pinard@iro.umontreal.ca>
5359 * m4.h: Include <unistd.h> if it exists.
5360 * stackovf.c: Don't.
5362 Clean up for current_diversion variable:
5363 * output.c: Move current_diversion from builtin.c.
5364 * m4.h: Declare current_diversion so builtin.c can access it.
5365 * output.c (output_init, make_diversion): Initialize or update
5367 * builtin.c (builtin_init, m4_divert): Leave current_diversion

5374 * m4.h, m4.c: Remove NDIVERSIONS and ndiversion related stuff.
5375 * m4.c: Still accept -N, but do nothing with it.
5376 Reported by David MacKenzie.
5379 * output.c (freeze_diversions): New function.
5380 * m4.h: Declare freeze_diversions.
5381 * freeze.c: Document frozen file format, revise it, call
5382 freeze_diversions to add diversions to frozen format, and code to
5383 reload them properly.
5384 * m4.c: Do not undivert automatically at end when status being
5385 frozen. Do not call builtin_init when reloading frozen state.
5387 Speed up diversion processing:
5388 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
5389 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
5390 structure and variables, cached variables out of output_diversion,
5391 reallocate_diversion_for and OUTPUT_CHARACTER.
5392 (shipout_text, make_diversion, insert_diversion): Adapted to new
5394 (insert_file): Use better buffering.

5400 dist works from another build directory.
5402 1994-08-27 François Pinard <pinard@iro.umontreal.ca>
5404 * symtab.c (hack_all_symbols): Use hash_table_size instead of
5405 constant HASHMAX, for -H option to work better.
5407 * builtin.c (DECLARE): Simplify by using _ ().
5409 * freeze.c: New file.
5410 * Makefile.in: Compile it, distribute it.
5411 * m4.c: Recognize, document and process --freeze-state (-F) and
5412 --reload-state (-R) options. Pass a true flag to builtin_init
5413 only if no reloading some state.
5414 * builtin.c (define_builtin): Remove static specifier.
5415 (find_builtin_by_name): Remove static specifier.

5431 Reported by Akiko Matsushita.
5433 1994-08-12 François Pinard <pinard@iro.umontreal.ca>
5435 * m4.h: Include <sys/types.h>.
5436 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
5437 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
5439 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
5441 * builtin.c (dump_args): Declare len as size_t, not int.
5443 * debug.c: Prototype the forward declaration of debug_set_file.
5445 * builtin.c (m4_undivert): Replace div by file, for avoiding the
5446 shadowing of this variable.
5447 * output.c (insert_diversion): Idem.
5449 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
5450 (input_init): Duplicate default quote and comment strings.
5451 (set_quotes): Free previous quote strings in all cases. Duplicate
5452 even default quote strings.
5453 (set_comment): Free previous comment strings in all cases.

5457 * Makefile.in (distclean-local): Also delete config.cache.
5459 * m4.c (usage): Reorganize the --help output by topic. Include a
5460 description for debugging flags.
5462 1994-07-29 François Pinard <pinard@iro.umontreal.ca>
5464 * configure.in: If sigaction is available and SA_ONSTACK defined,
5465 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
5466 defined, use sigvec. Else don't compile stackovf.c.
5467 * stackovf.c (setup_stackovf_trap): Idem.
5468 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
5471 1994-07-21 François Pinard <pinard@iro.umontreal.ca>
5473 * m4.c (usage): Replace printf par fputs.
5475 1994-07-18 François Pinard <pinard@iro.umontreal.ca>
5479 1994-07-17 François Pinard <pinard@iro.umontreal.ca>
5481 * configure.in: Check for sigaction and sigvec. Add a new delayed
5482 check for RLIMIT_STACK, combine in the checking for getrlimit.
5483 All those things are not universally available.
5484 * stackovf.c: Split setting up the trap handler and catching
5485 signals, for better taking care of various configure outcomes.
5486 * examples/stackovf.sh: Correct a typo.
5487 Reported by Eric Backus, Jim Avera and Jim Meyering.
5489 1994-07-16 François Pinard <pinard@iro.umontreal.ca>
5491 * ansi2knr.c: New version sent by its author, Peter Deutsch.
5493 1994-07-15 François Pinard <pinard@iro.umontreal.ca>
5495 * Makefile.in: Modify so parallel make will not try making
5496 lib/libm4.a twice simultaneously.
5497 Reported by Jim Meyering.
5499 1994-07-14 François Pinard <pinard@iro.umontreal.ca>
5501 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
5502 error message, for when no code possibility exists. Even if this
5503 line is completely #ifdef'ed out, it brings a syntax error.
5504 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
5506 * Makefile.in (install): Have install depend on all too, for lib
5507 to be remade as needed.
5509 * examples/stackovf.sh: Try ksh, bsh and bash for shells
5510 providing ulimit, instead of using only ksh.
5511 Reported by Jim Avera and Joseph E. Sacco.
5513 1994-07-12 François Pinard <pinard@iro.umontreal.ca>
5515 * Makefile.in (check): Have it depend on all instead of m4. In
5516 this way, a change in lib will be detected and processed.
5518 * builtin.c (numeric_arg): Use strtol and verify the conversion,
5519 instead of using sscanf which stops as soon as there is a
5520 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
5521 and divert(1xyzzy) were all accepted without any warning or error
5523 * m4.h: Declare strtol as long if not including stdlib.h.
5524 * configure.in: Check for limits.h, and replace strtol if missing.
5525 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
5526 * lib/strtol.c: New file, from elsewhere.
5527 Reported by Andreas Schwab.
5529 1994-07-07 François Pinard <pinard@iro.umontreal.ca>
5531 * macro.c (expand_macro): Cast value to (boolean) prior to
5532 assigning it to traced.
5533 Reported by Tom McConnell.
5535 * Makefile.in (m4): Always make all in lib first.
5536 Reported by Jim Meyering.
5538 1994-07-06 Jim Avera <jima@netcom.com>
5540 * stackovf.c: Isolated OS-dependent sections; Improved portability,
5541 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
5542 handlers), and a default error message if the fault address is not
5543 available (when neither siginfo.h nor BSD sigcontext are supported).
5544 * configure.in: Changes for stackovf.h: Check for sigcontext,
5545 sigaction, sigstack, and define rlim_t as int if necessary.
5546 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
5547 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
5548 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
5550 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
5552 * configure.in: Use AC_SET_MAKE.
5553 * Makefile.in: Use @SET_MAKE@.
5554 Reported by Jim Meyering.
5556 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
5557 Reported by Ian Taylor.
5559 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
5561 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
5562 because siginfo.h is unrelated to standard headers, and siginfo.h
5563 is already checked for.
5564 Reported by Joseph E. Sacco.
5566 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
5568 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
5571 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
5573 * builtin.c (substitute): Use \& to represent this part of the
5574 string which was matched by the whole regexp, instead of
5575 representing the whole string. Any usage of \0 issues a warning
5576 and acts like \&, it will disappear in some subsequent release.
5578 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
5580 * m4.c: Complete prototype for forwarded declaration of usage.
5582 * input.c (init_macro_token): Correct own reference in error
5583 message. Previous name get_macro_func was referred to instead.
5584 (next_char): Correct own reference in error message. Previous
5585 name advance_input was referred to instead.
5587 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
5588 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
5589 and_term, not_term, logical_not_term, cmp_term, shift_term,
5590 add_term, mult_term, exp_term, unary_term, simple_term): Add
5591 prototype to forwarded declarations. Declare parameter v1 as
5592 eval_t * instead of int *. Same for local variable v2 in dyadic
5593 functions. Same for result in exp_term.
5594 * builtin.c (m4_eval): Declare value as eval_t instead of int.
5595 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
5596 unsigned_eval_t instead of unsigned int. Change casts accordingly.
5597 (shipout_int): Cast first argument of ntoa to eval_t.
5598 Reported by Thorsten Ohl.
5600 * macro.c: Complete the prototypes of forwarded expand_macro and
5602 Reported by Thorsten Ohl.
5604 * m4.h: Define voidstar as void * or char * depending on __STDC__.
5605 The Ultrix 3.1 compiler cannot do much with void pointers.
5607 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
5608 * m4.c (xfree): Replace void * by voidstar.
5609 Reported by Tom McConnell.
5611 * ansi2knr.1: New, from elsewhere.
5612 * Makefile.in (DISTFILES): Distribute ansi2knr.1
5614 * Makefile.in (stamp-h.in): Avoid running ./config.status if
5615 stamp-h does not exist yet. This avoids running it a second time
5616 just after the initial ./configure.
5617 Reported by David MacKenzie and Tom McConnell.
5619 * m4.h: Replace the enum debug_info declaration with a series of
5620 #define's. The Ultrix 3.1 compiler would otherwise need casting
5621 (int) to most references, when used in expressions.
5622 Reported by Tom McConnell.
5624 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
5626 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
5627 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
5628 calls the compiler. Previously, FP_PROTOTYPES was only calling
5629 the preprocessor; by not being subject to CFLAGS, this was
5630 discouraging those flags asking for ANSI compilation.
5631 * acconfig.h: Document HAVE_PROTOTYPES.
5632 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
5633 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
5634 Reported by Eric Backus.
5636 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
5637 from the environment. Default CFLAGS to -g if not set.
5638 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
5639 * lib/Makefile.in: Have CFLAGS substituted from configure.
5640 Reported by Eric Backus and Tom McConnell.
5642 * configure.in: m4_undefine changeword before using AC_ENABLE.
5644 * m4.h: Declare prototypes for error (for ANSI compilers only),
5645 prefix_all_builtins and reference_error.
5646 Reported by Tom McConnell.
5648 * input.c (set_word_regexp): Do not try to initialize the array
5649 test from a string, this does not work with non-ANSI compilers.
5650 Reported by Eric Backus.
5652 * Makefile.in (dist): Clean examples/ before saving it.
5653 (distclean-local): Also remove stamp-h.
5654 Reported by Eric Backus.
5656 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
5658 Reported by Tom McConnell.
5660 * checks/Makefile.in (clean): Depends on mostlyclean.
5661 (mostlyclean): New goal.
5663 1994-06-24 François Pinard <pinard@iro.umontreal.ca>
5665 * Makefile.in (DISTFILES): Distribute install.sh.
5666 * install.sh: New file, copied from elsewhere.
5667 Reported by Assar Westerlund and Kaveh R. Ghazi.
5669 1994-06-23 François Pinard <pinard@iro.umontreal.ca>
5671 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
5672 * acconfig.h: Explain ENABLE_CHANGEWORD.
5674 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
5675 from code provided by Pete Chown]
5676 * m4.h: Add original_text field to u_t variant of union u.
5677 Declare TOKEN_DATA_FUNC macro.
5678 * builtin.c: Declare changeword.
5679 (m4_changeword): New function.
5680 * input.c: Include "regex.h", define variables with word regexps.
5681 (input_init): Initialize the word regexp.
5682 (set_word_regexp): New.
5683 (next_token): Declare local variables, use the previous code if
5684 default_word_regexp is true. Else, match using a new code. Save
5686 * macro.c (expand_token): Ship out original text if not a macro
5688 Reported by Krste Asanovic and Pete Chown.
5690 [These modifs all depend upon ENABLE_CHANGEWORD]
5691 * m4.h: Declare external user_word_regexp.
5692 * m4.c: Declare user_word_regexp, and initialize it from
5693 --word-regexp or -W, or NULL if not specified.
5694 * input.c: Use user_word_regexp if specified, instead of
5695 DEFAULT_WORD_REGEXP.
5697 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
5700 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
5701 * checks/Makefile.in: Empty the suffix list.
5702 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
5704 * m4.c: Declare nesting_limit and initialize it to 250.
5705 Implement -LNUMBER or --nesting-limit=NUMBER to change its
5707 * m4.h: Declare nesting_limit as external.
5708 * macro.c (expand_macro): Stop execution whenever nesting limit
5710 Reported by Bengt Mertensson.
5712 * eval.c (evaluate): Diagnose excess characters in eval input.
5713 Things like `eval(08)' used to return 0 with no diagnostic.
5715 * m4.h: Capitalize first letter of all macro arguments in
5718 * m4.c: Declare warning_status, initialize it to 0. Add new
5719 option -E, or --fatal-warnings, which sets warning_status to
5720 EXIT_FAILURE instead.
5721 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
5722 EXIT_FAILURE if not otherwise done by header files.
5723 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
5724 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
5725 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
5726 argument of all M4ERROR calls.
5727 Reported by Noah Friedman.
5729 * examples/incl-test.m4: Renamed from incl_test.m4.
5730 * examples/include.m4: Include incl-test.m4 instead of
5732 * examples/multiquotes.m4: Renamed from multi-quotes.m.
5734 1994-06-22 François Pinard <pinard@iro.umontreal.ca>
5736 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
5737 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
5738 also tested it on a Sun Sparc workstation running SunOS 4.x.
5740 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
5741 49.format check, abusing a `union values' argument with sprintf
5742 without selecting the proper field. Now, save the formatting type
5743 first, delaying the fetch of the corresponding argument.
5744 Reported by Joseph E. Sacco and Tom Quinn.
5746 * format.c (format): Remove const from char *fmt declaration when
5747 not HAVE_EFGCVT, because a NUL may be forced into it.
5749 * m4.h: Declare atof() when not STDC_HEADERS.
5750 Reported by Joseph E. Sacco.
5752 * Regenerate configure using Autoconf 1.11, this corrects a
5753 problem about an incorrect cpp seting on NeXT 3.1.
5754 Reported by Alexander Lehmann.
5756 1994-06-05 François Pinard <pinard@iro.umontreal.ca>
5758 * m4.h (_): Change argument from `x' to `Args'.
5760 1994-04-22 François Pinard <pinard@iro.umontreal.ca>
5762 * m4.h: Rename Args() to _().

5768 * configure.in: Check for getrlimit, sigaction. If all of
5769 standard headers, getrlimit and sigaction, define USE_STACKOVF and
5770 substitute ${U}stackovf.o for STACKOVF.
5771 * acconfig.h: Declare USE_STACKOVF.
5772 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
5773 * m4.h: Declare setup_stackovf_trap().

5775 * tests/stackovf_test.sh: New file.
5777 1994-04-13 François Pinard <pinard@iro.umontreal.ca>
5779 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
5781 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
5783 1994-01-30 <pinard@iro.umontreal.ca>
5785 * m4.h: Remove definition of volatile, not used anymore.
5786 Reported by Jim Meyering and Joseph E. Sacco.
5788 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
5789 of `if ... else /* nothing */' for if macros.
5790 Reported by Jim Meyering.
5792 * builtin.c (m4_regexp): Reorganize the code for avoiding a
5793 warning from gcc about `repl' possibly used before defined.
5794 Reported by Jim Meyering.
5796 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
5797 Reported by Jim Meyering.
5799 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
5801 * m4.h: Move the conditional definition of volatile after the
5802 inclusion of system files, because they may define it first.
5804 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
5806 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
5807 get around a problem with Alpha make seeing a syntax error, there.
5808 Reported by Vern Paxson.
5810 1994-01-03 François Pinard <pinard@iro.umontreal.ca>
5812 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
5813 Reported by Richard Stallman.
5815 1993-12-25 François Pinard <pinard@iro.umontreal.ca>

5823 * m4.c: Initialize show_help and show_version to zero.
5825 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
5826 Use them in exit() and usage() calls.
5828 1993-11-27 François Pinard <pinard@iro.umontreal.ca>
5830 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
5831 syserr() macro. Delete errref, add reference_error and M4ERROR.
5832 * m4.c: Replace errref, which was returning an input reference
5833 string, with reference_error, which prints it on standard error.
5834 * builtin.c, output.c: Use errno as second parameter to error,
5835 instead of using syserr() with %s.
5836 * *.c: Use M4ERROR instead of error: no more errref() with %s.
5837 Doing so, the program name appears after the input reference
5838 instead of before, which eases M-x next-error processing.
5840 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
5842 * checks/get-them: Escape braces with backslashes in patterns,
5843 because HPUX-9.01 awk needs this.

5852 Declare xrealloc, for use in errref().
5853 * m4.c: Delete error_message_prefix() function, add errref().
5854 * *.c: Use error() systematically in place of all error macros,
5855 now that error() flushes stdout first. Make needed adjustments.
5857 * m4.h: Remove const in sys_errlist[] declaration, it creates
5858 conflicts on SGI and Alpha.
5859 Reported by Kaveh R. Ghazi.
5861 1993-11-20 François Pinard <pinard@iro.umontreal.ca>

5879 * input.c (input_init): Initialize quote and comment strings
5880 explicitely instead of calling set_quotes and set_comment: by
5881 doing so, we ensure we do not free uninitialized variables.

5884 expected is on the left and the obtained on the right.
5886 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
5887 macros. Delete declarations for m4error, warning, fatal and
5888 internal_error, add declaration for error_message_prefix.
5889 * m4.c: Delete m4error, warning, fatal and internal_error
5890 routines, add error_message_prefix routine.
5891 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
5892 warning with WARNING*, fatal with FATAL* and internal_error with
5894 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
5895 this is not needed anymore.
5897 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
5898 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
5899 and debug_message, add declaration for debug_message_prefix.

5910 (trace_format): Use stdarg instead of varargs if __STDC__.
5912 * configure.in: Remove checks for vfprintf and _doprnt. These
5913 implementations use varargs tricks which are not portable enough.

5936 Reported by Joel Sherrill.
5938 * builtin.c (prefix_all_builtins): Instead of the table size, use
5939 the null entry at end for stopping the loop. It was overwritten.
5940 Reported by Andreas Schwab and Jim Meyering.
5942 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
5943 Reported by Kaveh R. Ghazi.

6022 Reported by Jim Avera.
6024 * builtin.c (m4_ifelse): Diagnose excess arguments if 5, 8, 11,
6025 etc., arguments, then ignore the superfluous one. m4 used to
6026 diagnose missing arguments and return the empty string.

6198 * lib/alloca.c: New, from elsewhere.
6199 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
6201 * m4.h: Do not define index/rindex if already defined. If
6202 FALSE/TRUE are already defined, do not redefine them, but merely
6203 define boolean typedef to int.
6205 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
6206 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
6207 because some C compilers do not like connectives with #ifdef.

6209 __GNUC__ and once for __STDC__.
6210 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
6212 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
6213 Makefile dependencies. Without it, make keeps destroying and
6214 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
6216 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
6217 to diversion/DIVERSION, this was a spelling error.

6221 * Makefile.in: Remove references to version.h.
6223 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
6224 production, by using a simpler and more robust algorithm. This
6225 solves the problem of synclines sometimes written in the middle of
6226 an output line. Delete sync_line() and output_lines variable.
6227 * m4.h: Remove sync_line prototype and output_lines declaration.
6228 * input.c (next_char), output.c (shipout_text): Remove references
6230 * input.c (push_file, pop_file): Merely put the value -1 in
6231 output_current_line instead of calling sync_line, for delaying a
6232 single `#line NUM FILE' before next output line. Do not test
6233 for sync_output, because this is unnecessary clutter.
6234 * output.c (make_divertion, insert_divertion): Idem.
6235 * input.c: Rename must_advance_line to start_of_input_line, for
6238 * debug.c (trace_header): Select a new debug line format, which
6239 better complies with GNU standards for formatting error messages.
6240 With option `-dfl', M-x next-error might be used on the output.
6241 * m4.c (vmesg): Adjust format of error output to GNU standards.
6242 * m4.texinfo: Adjust examples for `make check' to work.
6244 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
6245 case for enum debug_info constants, which were all lower case.
6247 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
6249 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
6250 collected patches. I tried a few times using newer regex.[ch], it
6251 mysteriously stopped aborting with this one. Insecure feeling...
6252 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
6254 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
6256 * m4.c: Change `--no-warnings' to `--silent'.
6257 Reported by David MacKenzie.
6259 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
6260 leave it off for now. See comment in m4.c for justification.
6261 Reported by David MacKenzie.
6263 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
6264 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
6266 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
6268 * Makefile.in: Ensure recursive cleaning is done before local
6269 cleaning for all clean goals.
6271 * builtin.c (ntoa): Ensure the value is always interpreted as a
6272 signed quantity, whatever the radix is.
6274 1992-11-18 Jim Meyering <meyering@idefix>
6276 * builtin.c, format.c, input.c: Split long lines.
6277 * m4.c: Use typedef macro_definition instead of struct
6279 * symtab.c: Use typedef symbol instead of struct symbol.
6281 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
6283 * *.[ch]: Remove all trailing whitespace, in code and comments.
6285 * configure.in: Find some awk.
6286 * Makefile.in: Add $(AWK) to MDEFINES.
6287 * checks/Makefile.in: Transmit $(AWK) to get_them.
6288 * checks/get_them: Use $AWK instead of gawk. Add a close in the
6289 awk script when switching files, because without this, mawk runs
6290 out of file descriptors.
6292 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
6294 * Makefile.in (realclean): Delete m4.info*.

6302 recognizable by next-error, also use a better message.
6304 1992-11-16 Jim Meyering <meyering@idefix>
6306 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
6307 And use that only if __GNUC__ since we're using it's GCC-specific
6308 semantics that tell the compiler the associated function doesn't
6311 * builtin.c (substitute): Don't use character as an array index.
6312 (dumpdef_cmp): Make formal arguments `const void *' to avoid
6313 warnings with gcc -W -Wall on systems with qsort prototype.
6314 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
6317 * eval.c (most functions): Add parentheses to assignments used
6318 as truth values go avoid warnings from gcc -Wall.
6320 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
6321 any functions that don't need external scope.
6323 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
6324 (many functions and arrays): Declare `const'.
6326 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
6328 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
6329 removing the declaration from m4.h. Also rename false to FALSE
6332 * lib/Makefile.in (Makefile): New goal.
6334 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
6335 so heavily loaded. It gets more easily overridable, calling make.
6336 Reported by Jim Meyering.
6338 * Makefile.in (dist): Get .fname from the current directory name,
6339 instead of from version.h. I need updating many files manually,
6340 when the version changes, version.h is just one of them.
6342 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
6344 * m4.h: Remove the tag `boolean' on the enum introducing typedef
6345 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
6346 Reported by Tom McConnell.
6348 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
6350 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
6351 39.cleardiv, which were describing missing or spurious newlines.
6352 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
6353 do not depend on machine word size, `/bin/false' implementation,
6354 or `wc' output format. `make check' is more dependable, now.
6356 * checks/check_them: Summarize the failed tests by listing their
6357 name, at end. If none, issue `All checks successful'. Output
6358 `Checking' instead of `Input file:'.
6360 * checks/get_them, checks/check_them: Reindented.
6362 * Makefile.in (dist): chmod a+r before making the tar file.
6364 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
6366 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
6368 * input.c (next_token): Reinitialize token_buttom just after using
6369 it as a watermark with obstack_free. Or else, a future token, big
6370 enough for triggering reallocation of the obstack chunk, could
6371 void the initialized value of token_buttom, later causing panic in
6372 obstack_free. Rename token_buttom to token_bottom everywhere.
6374 * m4.h: Before declaring errno, first include <errno.h> and
6375 ensure that it does not define errno.
6376 Reported by Richard Stallman.
6378 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
6380 * builtin.c: Define and use DECLARE macro for builtins.
6382 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
6383 argument, this is a common idiom for introducing long comments.
6385 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
6386 arguments. The last argument was silently ignored.
6388 * m4.c (cmd_error): Add a missing semicolon before va_end().
6390 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
6392 * Makefile.in: Now handle protoized sources. Define and use U.
6393 Compile and use ansi2knr with old compilers. Update DISTFILES.
6394 Add `aclocal.m4' to `configure' dependencies.
6395 * ansi2knr.c: New, from Ghostscript distribution.
6396 * configure.in: Define U through FP_PROTOTYPES for old compilers.
6397 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
6398 * aclocal.m4: New, provide FP_PROTOTYPES.
6399 * m4.h: Conditionnaly protoized through Args, save for varags.
6400 * builtin.c: Protoized. Then:
6401 Include <sys/types.h> if size_t is not defined, before "regex.h".
6402 (m4_ifelse): Fetch built-in name properly for diagnostic.
6403 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
6404 (m4_regexp): Add const to `msg' declaration.
6405 (m4_patsubst): Add const to `msg' declaration.
6406 * debug.c: Protoized, save for varargs.
6407 * eval.c: Protoized.
6408 * format.c: Protoized.
6409 * input.c: Protoized.
6410 * m4.c: Protoized, save for varargs. Then:
6411 (xfree): Accept void * instead of char *.
6412 (xmalloc): Return void * instead of char *.
6413 (xrealloc): Accept and return void * instead of char *.
6414 * macro.c: Protoized.
6415 * output.c: Protoized.
6416 * path.c: Protoized. Then cast some (char *) over xmalloc's.
6417 * symtab.c: Protoized.
6419 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
6421 * m4.texinfo: Remove directory from diagnostics in 30.include,
6422 51.eval, 56.errprint and 57.m4exit tests.
6424 * m4.h: Remove declarations for int or void system functions, they
6425 cause more conflicting trouble than they make good.
6427 * configure.in: Avoid configuration header file. Add some tests.
6428 * m4.h: Remove #include "config.h".
6429 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
6430 Then, rewritten for better compliance with GNU standards.
6432 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
6434 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
6435 because of a misplaced #endif.
6437 * Many *.[hc] files: Correct intra-line spacing here and there,
6438 according to GNU indent 1.6 advice.
6440 * configure.in: New, using Autoconf 1.2.
6441 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
6442 * Delete old configure.in, configure, etc/configure.in,
6443 etc/configure, lib/configure.in, lib/configure and config/*.
6444 Reported by Jason Merrill.
6446 * symtab.c (hash): Change (char) NULL to '\0'.
6447 Reported by Jason Merrill.
6449 * Delete .vers, etc/newdist.sh, etc/newvers.sh and

6451 * version.h: De-automatize, force value in.
6453 * m4.c: Changes in order to use a newer getopt.h.
6454 Reported by David MacKenzie.
6456 * checks/: New name for examples/.
6457 * checks/get_them: New location for etc/get_examples.
6458 * checks/check_them: New location for etc/check_examples.
6459 * Makefile.in, checks/get_them, checks/check_them: Adjust.
6460 * lib/vfprintf.c: New location for etc/vfprintf.c.
6461 * Delete empty etc/.
6462 * examples/: New name for test/.
6464 1992-03-10 François Pinard <pinard@iro.umontreal.ca>
6466 * Makefile.in (check): Add m4 as dependency.
6468 * m4.c: Accept --no-warnings instead of --no_warnings, and
6469 --no-gnu-extensions instead of --no_gnu_extensions. Make the
6470 usage message more informative.

6487 Reported by Richard Stallman.
6489 * config/hmake-unicos, config/s-unicos.h: New files.
6490 Reported by Hal Peterson.
6492 * eval.c (exp_term): Have N^0 return 1.
6493 Reported by Michael Fetterman.
6495 * eval.c, input.c, m4.h: Remove last comma in enums.
6496 Reported by Mike Lijewski.
6498 * Transfer of maintenance duties from René to François.
6500 1991-10-24 René Seindal <seindal@diku.dk>

6510 missing or superflous arguments to built-in macros.
6512 * Added default options via the M4OPTS environment variable.
6514 * The built-in format can now be configured to use sprintf as
6515 the formatting engine, for systems without [efg]cvt(3).
6517 * GNU library code is moved to the ./lib subdirectory; other
6518 utility files are now in ./etc.
6520 * Several minor bugs have been fixed.
6522 1991-07-26 René Seindal <seindal@diku.dk>

6525 Francois Pinard and Roland H. Pesch for providing me with reports.
6527 * The builtins incr and decr are now implemented without use of
6530 * The builtin indir is added, to allow for indirect macro calls
6531 (allows use of "illegal" macro names).
6533 * The debugging and tracing facilities has been enhanced
6534 considerably. See the manual for details.
6536 * The -tMACRO option is added, marks MACRO for tracing as soon
6539 * Builtins are traced after renaming iff they were before.
6541 * Named files can now be undiverted.
6543 * The -Nnum option can be used to increase the number of
6544 divertions available.
