28 Fix all testsuite failures on cygwin.
29 * doc/m4.texinfo (Syscmd, Esyscmd): Forward-port updates from
30 branch-1_4. Solves testsuite failure when uninstalled m4 is
31 shadowed by redefinition of PATH in libtool wrapper.
32 * Makefile.am (module_ldflags): Don't forget AM_LDFLAGS, which
33 contains the -no-undefined required by cygwin.
34 (TESTS_ENVIRONMENT): Export abs_top_builddir.

44 The regs_allocated field in a struct re_pattern_buffer refers
45 to the state of a particular re_registers struct when used in
46 successive matches using the same compiled pattern. Avoid a
47 SEGV in `renamesyms' resulting from using a new re_registers
48 with an existing re_pattern_buffer:
50 * modules/gnu.c (m4_pattern_buffer): Wrapper struct for associated
51 pattern buffer and registers.
52 (m4_regexp_search): New function to call re_regexp_search with
53 correctly matched pattern buffer and register instantiations.
54 (m4_regexp_compile): Return an m4_pattern_buffer. Adust all

77 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
79 * Makefile.am (src_m4_DEPENDENCIES): Make dependency explicit.
80 (clean-local): Split into and depend upon...
81 (clean-local-tests, clean-local-src): ...these two. The latter
82 removes the libtool object directory below `src', to work around
83 a buglet in Automake, failing to list it.
84 (EXTRA_DIST): Distribute modules/perl.c.
86 2006-06-19 Eric Blake <ebb9@byu.net>
88 * Makefile.am ($(srcdir)/doc/m4.1): No need to list $(srcdir) in
89 right side of dependency; VPATH does that.
90 (stamp-vcl): Update to use libtool's algorithm.
91 (EXTRA_DIST): Distribute stamp-vcl.
92 Reported by Ralf Wildenhues.
93 (TESTSUITE): Revert earlier change that used absolute path, as
94 that broke 'make dist' in VPATH. Stick with $(srcdir) instead.
95 (EXTRA_DIST): Revert earlier change of $(TESTSUITE).
96 (TESTS_ENVIRONMENT) [USE_GMP]: Revert earlier addition, since
97 atlocal takes care of it instead.
98 (check-local, installcheck-local, clean-local): Inline absolute
99 path to testsuite here, rather than relative path to testsuite
102 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
104 * m4/m4private.h (DELETE): Cast away const here...
105 * src/stackovf.c (stackovf_exit): ...to avoid cast-as-lvalue here.
106 * src/freeze.c (reload_frozen_state): Avoid uninitialized
109 2006-06-19 Eric Blake <ebb9@byu.net>

119 Follow recommendations from autoconf manual for autotest.
120 * Makefile.am (TESTSUITE): Factor the $(srcdir) out of uses, and
121 turn it into an absolute path until autotest provides an option
122 that allows us to avoid changing directories. Properly quote
124 (TESTS_ENVIRONMENT) [USE_GMP]: Inform testsuite about GMP.

150 (M4_DEFAULT_PRELOAD): Use as a macro, not shell variable.
151 * Makefile.am (src_m4_CPPFLAGS): Use STACKOVF as a makefile
153 * ltdl/m4/m4-gnulib.m4: Delete, no longer needed.
155 Reduce compiler warnings. Inside GMP, mpq_t is an array type, so
156 const mpq_t is not assignable from plain mpq_t. Avoid
157 type-punning warnings caused trying to mix these types.
158 * modules/mpeval.c (numb_ior, numb_eor, numb_and, numb_lshift),
159 (numb_rshift, numb_divide, numb_modulo): Remove const qualifier.

183 * Makefile.am (AM_CPPFLAGS): Add $(LTDLINCL), so the right
186 * bootstrap: Do not run libtoolize manually, this is done
187 correctly by autoreconf. Invoke autoreconf with --no-recursive
188 to avoid unnecessary rerunning of autotools for libltdl.

200 * configure.ac (AC_CHECK_FUNCS): Remove obsolete checks.
201 * Makefile.am (doc/m4.1): Depend on installed help2man, rather
202 than distributing outdated helptoman.pl.
203 * doc/helptoman.pl: Delete.

217 (AC_CHECK_HEADERS, AC_FUNC_ALLOCA, AC_FUNC_VPRINTF): Remove checks
218 done by gnulib or automake, or which autoconf has declared

234 * ChangeLog: Change encoding to UTF-8.
236 Avoid compiler warnings.
237 * m4/macro.c (trace_format): Don't mark this as a printf format,
238 since we don't accept the same set of modifiers as printf. It
239 would be nice if gcc let us specify a custom format archetype.
240 * src/main.c (main): Cast away const.
242 2006-06-10 Andreas Schwab <schwab@suse.de> (tiny change)

286 2005-12-05 Gary V. Vaughan <gary@gnu.org>
288 * bootstrap (func_update_po): Synch with CVS GNU tar. wget 1.9.x
289 and 1.10.x support --cache=off, so $WGETFLAGS are not necessary.
290 Reported by Eric Blake <ebb9@byu.net>
292 2005-12-04 Gary V. Vaughan <gary@gnu.org>
294 * bootstrap (func_update_po): Test and set $WGETFLAGS to disable
295 http caching as -C is no longer supported by wget 1.10.x.

302 (iface_id): ...an lt_dlinterface_id type.
303 (m4__module_find): New abstraction for lt_dlhandle_fetch. Use
304 throughout, instead of calling obsolete lt_dlhandle_find directly.
305 (m4__module_next): Use multiloader-safe lt_dlhandle_iterate. Use
306 throughout, instead of calling obsolete lt_dlhandle_next.
307 * m4/m4private.h (m4__module_find): Declare it.

316 po/ja.po, po/nl.po, po/pl.po, po/ru.po, po/sv.po: No need to store
317 these files under source control anymore.

320 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
322 * ltdl/m4/m4-gnulib.m4: Update FSF contact address. Somehow this
323 file escaped the address updates on 2005-05-01.
325 2005-07-07 Gary V. Vaughan <gary@gnu.org>
327 * bootstrap: Allow user overriding of gnulib-tool location, and
328 correctly determine module source directories whether gnulib-tool
329 is given as a relative or absolute path, or is found by searching

356 macro renaming by regular expression.
357 * doc/m4.texinfo (Erenamesyms and Renamesyms): Document them.
358 * tests/generate.awk: Allow some forbidden `m4_' prefixed symbols
359 to stop the new generated tests from choking.
361 2005-05-07 Gary V. Vaughan <gary@gnu.org>
363 Since most of the build is handled from a single Makefile.am now,
364 we can teach make about the dependencies between the m4 binary and
365 the preopened modules it is built against:
367 * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
369 * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
370 of the preopened modules have changed.
372 2005-05-07 Gary V. Vaughan <gary@gnu.org>
374 * configure.ac (gl_MODULES): Add mkstemp for machines that don't
375 have a native implementation.
377 2005-05-06 Gary V. Vaughan <gary@gnu.org>
379 * src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are
380 handled already by gnu/exit.h.
382 * configure.ac (gl_MODULES): Add assert to support a
383 --disable-assert configure time option for NDEBUG setting.
385 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.
386 * bootstrap (src_modules): Add version-etc-fsf.
387 * src/main.c (version_etc_copyright): Removed.

401 Forward port of a patch that allowed m4-1.4.2 to compile on
404 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
406 * src/m4.h: And include them as appropriate.
407 * src/main.c, src/stackovf.h: Don't include signal.h literally;
408 m4.h will include the correct file.

412 * m4/m4private.h: Make errno visible for the sources patched
415 2005-05-04 Paul Eggert <eggert@twinsun.com>

419 * modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
420 * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
421 * m4/path.c (m4_path_search): Don't let "free" trash errno when
424 * m4/output.c (m4_insert_file): Don't assume errno has a valid
425 value simply because fread returns zero. This fixes a
426 portability bug reported by Marion Hakanson in
427 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
429 2005-05-04 Santiago Vila <sanvila@debian.org>

437 unbuffered I/O, as this breaks on the Hurd.
439 2005-05-04 Gary V. Vaughan <gary@gnu.org>
441 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
442 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
443 and libtoolize does a better job of ltdl importing now too, so
444 take advantage of that while updating the tree:
446 * acm4, config: Moved from here...
447 * ltdl/m4, ltdl/config: ...to here.
448 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
449 src/Makefile.am, tests/Makefile.am: Removed...
450 * Makefile.am: ...and migrated to here, with adjustments to
451 compensate for relative path differences.
452 * commit: Adjust relative paths.
453 * configure.ac: Adjust relative paths.
454 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
456 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
457 the meanwhile, CVS HEAD libtool is needed.
458 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
459 stricly new enough, we also need a patch.
460 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
461 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
462 (gl_MODULES): Don't list getopt and version-etc, as they don't
464 * bootstrap: After running gnulib-tool to import the listed
465 modules, fetch getopt and version-etc into src manually.
466 (ltdldir): Change to ltdl.
467 * src/main.c: Adjust for changes in version-etc API.
468 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
469 but works when the getopt module isn't to be included in the lib.
470 * README: Add note about patching autoconf and automake to

476 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
477 empty file rather than to a nonexistent file. This closes a
478 common security hole.

480 mkstemp rather than mktemp.

525 Protect definitions from macro expansion under -DNDEBUG by
526 parenthesising the expanded function names.
527 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
528 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
529 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
530 (m4_is_syntax_macro_escaped): Similarly protect function
531 definitions from macro expansion under -DNDEBUG by #undefing the
532 matching macro names before each definition. Also, move all the
533 function definitions to the end of the file so that any
534 invocations in the rest of the file pick up the fast macro
536 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)
537 (m4_set_debug_file, m4_set_trace_messages)
538 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
539 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
540 (m4_set_max_debug_arg_length_opt): New fast macro versions of the
541 option setter functions.
543 2004-09-23 Gary V. Vaughan <gary@gnu.org>
545 * src/main.c: Include gnulib files from the correct directory.
547 * gnulib/*: Don't store any of the gnulib files in arch, as they
548 generate spurious changes.
549 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
550 gnulib macros now share our macro directory.
551 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
552 * bootstrap: Call gnulib-tool to import from the gnulib tree.
553 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
554 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
555 the gettext macros from autopoint that overwrite the gnulib-tool
556 imported versions. Import sources and Makefile.am into the `gnu'
557 directory. Changed all callers.
558 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
559 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
560 for imported modules.
561 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
562 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
563 hardcoding the gnulib macros they wrap.
565 2004-07-15 Gary V. Vaughan <gary@gnu.org>
567 Latest CVS libtool can preload modules in libraries, including
568 its own module loaders! Tweak m4 so that it doesn't try to treat
569 libltdl's module loaders as m4 modules when freezing and on exit:
571 * gnulib/acm4/*.m4: Don't store these files in arch since they
572 generate spurious changes.
573 * bootstrap: Simplify initial libtoolize call, since CVS
574 libtoolize is smarter these days.
575 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
577 * m4/module.h (m4__module_exit): Missing declaration.
578 * m4/m4private.h (m4__module_next): New function declaration.
579 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
580 encapsulation. Changed all callers.
581 (m4__module_interface): New function to verify m4 loadable module
583 (m4__module_init): Register the interface validator.
584 (m4__module_exit): Only close my own modules.
585 * modules/m4.c (unistd.h): Provide missing declaration.
586 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
587 (m4_expand_ranges): More missing declarations.
588 * modules/modtest.c (export_test): Ditto.
589 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
590 * src/main.c (main): Bump copyright year.
591 * tests/modules.at: Fix sed syntax error.
594 2004-06-17 Gary V. Vaughan <gary@gnu.org>
596 Tweaking to enable compilation with latest CVS libtool and
597 libltdl. We can't just dump the library files directly into the
598 m4 directory anymore now that libltdl is built from pieces itself:
600 * bootstrap: Rewritten to use latest libtoolize sanely, and to
601 set up libltdl subdirectory.
602 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
603 gnulib subdirectory's config.
604 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
605 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
607 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
608 configure.ac, so use AC_WITH_LTDL instead.
609 * Makefile.am (SUBDIRS): Add libltdl.
610 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
612 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
613 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
614 (libm4_la_LIBADD): Add LIBLTDL.
615 * m4/ltdl.c, m4/ltdl.h: Removed.
616 * m4/m4module.h: Include canonical ltdl.h.
619 2004-06-14 Gary V. Vaughan <gary@gnu.org>
621 * gnulib/import: Now updates makefile fragments, and configure.ac.
622 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
623 * gnulib/m4/Makefile.am: include it.
624 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
625 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
626 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
627 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
628 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
629 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,
630 gnulib/acm4/lib-ld.m4, gnulib/acm4/lib-prefix.m4,
631 gnulib/acm4/error.m4, gnulib/acm4/po.m4, gnulib/acm4/regex.m4,
632 gnulib/acm4/stdbool.m4, gnulib/acm4/stdint_h.m4,
633 gnulib/acm4/uintmax_t.m4, gnulib/acm4/ulonglong.m4,
634 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
635 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
636 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
638 * gnulib/m4/getopt_int.h: New source file from latest gnulib
640 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
641 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,
642 gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
643 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
644 Updated source files from latest gnulib.
646 2004-02-29 Gary V. Vaughan <gary@gnu.org>
648 * config/mailnotify: New file for mailing commit notifications,
649 imported from cvs-utils.
650 * commit: Updated from cvs-utils and tweaked for m4.
652 2003-12-01 Gary V. Vaughan <gary@gnu.org>
654 * config/mkstamp: Updated from CVS libtool.
655 * configure.ac: Generate a gnu coding standards compliant version
656 number, and use it for the banner.
657 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
658 mhen the TIMESTAMP changes in ChangeLog, but the file modification
659 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
660 contain the previous version number.
661 * src/main.c: Make --version output conform to the GNU standard.
663 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
664 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
665 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
666 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
667 time_la_SOURCES): ...so that these are defaulted correctly, and
668 can be removed from this file.
669 (AM_LDFLAGS): Add -module...
670 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
671 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
672 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
673 the individual settings can be removed.
674 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
675 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
676 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
677 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
678 time_la_LIBADD): ...so that these are picked up as a deplib of
679 libm4 and don't need to be set explicitly.
681 2003-11-18 Gary V. Vaughan <gary@gnu.org>
683 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
684 from the standard build. It is too fragile.
686 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
687 CVS libtool after merging m4 changes across to libtool.
689 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
690 * m4/path.c (search_path_add): Ditto.
692 2003-11-13 Gary V. Vaughan <gary@gnu.org>
694 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
695 libtool tags we don't use in configure. This reduces the size
696 of the script from over 1Mb to under 700Kb.
698 2003-11-13 Gary V. Vaughan <gary@gnu.org>
700 The import script was not written properly, and the last gnulib
701 import was incomplete. Fixed that problem, and reimport our
702 gnulib dependencies, which picks up the address calculation
703 overflow checks described by Paul below. Also tweak the clients
704 of the gnulib xalloc module not to use deprecated macros:
706 * gnulib/import: Recurse through module dependencies rather than
707 naively descending only one level.
708 * configure.ac: Add calls to gnulib's strnlen and extension module
710 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
712 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
713 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
714 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
715 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
717 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
718 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
719 place of `xcalloc (1, S)'.
720 * m4/m4.c (m4_create): Likewise.
721 * m4/m4private.h (m4_symbol_value_create): Likewise.
722 * m4/symtab.c (symtab_fetch): Likewise.
723 * m4/syntax.c (m4_syntax_create): Likewise.
724 * src/freeze.c (reload_frozen_state): Likewise.
725 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
727 * m4/symtab.c (m4_symtab_create): Likewise.
729 2003-11-13 Gary V. Vaughan <gary@gnu.org>
731 * tests/module.at: Comment typo.
733 2003-10-10 Gary V. Vaughan <gary@gnu.org>
735 * tests/modules.at (modules: importing): Apply some lateral
736 thinking, and use AT_CHECK to compare the output of a sed pass
737 over stderr against the canonical strerror string.
739 * tests/modules.at (modules: importing): Edit the generated stderr
740 output to canonicalize strerror output, before a comparison.
742 2003-10-10 Gary V. Vaughan <gary@gnu.org>
744 Tru64UNIX perl is sloppy with namespace pollution. This patch is
745 careful not to trip over the mess:
747 * modules/perl.c: Some builds of perl install headers that contain
748 `#define try __builtin_try'. Be sure to undefine that macro
749 before `m4/hash.h' gets included, which uses the `try' symbol.
750 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
751 `false' before including `stdbool.h'.
752 (DELETE): This symbol is not in m4's namespace, and is in any
753 case only used internally...
754 * m4/m4private.h (DELETE): ...so move it to here.
755 Reported by Martin MOKREJS <mmokrejs@natur.cuni.cz>
757 2003-10-08 Paul Eggert <eggert@twinsun.com>
759 Don't use XMALLOC and XCALLOC. Once we install the
760 corresponding patch into gnulib, this will fix some
761 address-calculation overflow bugs on hosts where calloc (A, B)
762 returns garbage when A*B overflows.
764 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
765 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
766 xmalloc, XCALLOC with xcalloc.
767 * m4/m4.c (m4_create): Likewise.
768 * m4/m4private.h (m4_symbol_value_create): Likewise.
769 * m4/output.c (m4_output_init): Likewise.
770 * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise.
771 * m4/syntax.c (remove_syntax_attribute): Likewise.
772 * src/freeze.c (reload_frozen_state): Likewise.
773 * src/main.c (main): Likewise.
775 2003-10-07 Gary V. Vaughan <gary@gnu.org>
777 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
778 gnulib/acm4 directories for aclocal m4 macros.
779 * gnulib/Makefile.am (EXTRA_DIST): Removed.
780 (MAINTAINERCLEANFILES): Add Makefile.in.
781 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
783 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
784 * gnulib/import: New file. Temporary script for updating gnulib
785 imported files, until gnulib-tool is working.
786 * gnulib/config/codeset.m4, gnulib/config/error.m4,
787 gnulib/config/exitfail.m4, gnulib/config/extensions.m4,

823 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
824 gnulib/acm4/xstrndup.m4: Reimported from CVS gnulib with
825 gnulib/import script.
826 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/error.c,
827 gnulib/m4/error.h, gnulib/m4/exitfail.c, gnulib/m4/free.c,

830 gnulib/m4/version-etc.c, gnulib/m4/version-etc.h,
831 gnulib/m4/xalloc.h, gnulib/m4/xmalloc.c: Updated from CVS
832 gnulib with gnulib/import script.
833 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
834 guards ready for gnulib-tool to autoupdate on import.
835 * config/debug.m4, config/gmp.m4, config/m4-error.m4,
836 config/m4-gettext.m4, config/m4-obstack.m4, config/m4-regex.m4,
837 config/stackovf.m4: Moved from here...

839 acm4/m4-gettext.m4, acm4/m4-obstack.m4, acm4/m4-regex.m4,

843 * m4/hash.c, m4/m4.c, m4/macro.c, m4/module.c, m4/output.c,
844 m4/path.c, m4/symtab.c, m4/syntax, m4/system_.h, modules/m4.c,
845 src/main.c, src/stackovf.c: s/xfree/free/g to comply with new

849 (version_etc): Call with new variadic API.
851 2003-09-16 Gary V. Vaughan <gary@gnu.org>
853 * gnulib/m4/version-etc.c, gnulib/m4/version-etc.h: Import
854 version-etc module from CVS gnulib.
855 * po/POTFILES.in: Add gnulib/m4/version-etc.c.
856 * src/Makefile.am: Build it.
857 * src/main.c: Use it.
859 * gnulib/m4/exit.h: Import exit module from CVS gnulib.
860 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
861 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
864 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
865 Gary V. Vaughan <gary@gnu.org>
867 * bootstrap: Separate options.
868 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
869 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
871 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
872 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
873 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
874 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
875 $(LTLIBINTL) for gettext support on cygwin.
876 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
877 have $(LTLIBINTL) from the preloaded module la files.
878 * README: Remove the warning about using --disable-nls on Windows
881 2003-09-15 Gary V. Vaughan <gary@gnu.org>
883 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
884 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
887 2003-09-12 Gary V. Vaughan <gary@gnu.org>
889 * doc/STYLE: Document the gnulib header naming conventions, and
891 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
892 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,
893 gnulib/m4/gettext.h, gnulib/m4/obstack.h, gnulib/m4/regex.h
895 * gnulib/m4/Makefile.am: Remove the rules to build these headers.
897 * gnulib/m4/strtol.c, gnulib/config/strtol.m4: Import strtol
898 module from CVS gnulib.
899 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
900 (gl_FUNC_STRTOL): In favour of the module macro.
902 2003-09-12 Gary V. Vaughan <gary@gnu.org>
904 Replace the getopt code with CVS gnulib getopt. The source files
905 detect whether they are in a glibc environment and preprocess away
906 all of the code if there is a system getopt, so we can compile
907 them into the m4 executable unconditionally:
909 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
910 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
911 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
913 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
915 * src/Makefile.am: Adjust.
916 * src/main.c: Always include our shipped getopt.h.
917 * po/POTFILES.in: Use new location of getopt.c.
919 2003-09-12 Gary V. Vaughan <gary@gnu.org>
921 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
922 * config/Makefile.am: Removed. Automake 1.8 distributes the files
923 in this directory automatically.
924 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
926 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
928 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
930 * modules/Makefile.am (pkglibexecdir): Set it here.
931 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
933 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
934 Import regex module from CVS gnulib.
935 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
936 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
937 do extra substitutions for Makefile.
938 * configure.ac: Use it.
939 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
940 from regex_.h if necessary.
941 * m4/system_.h: Include the correct version of regex.h.
942 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
944 * po/POTFILES.in: Use new location of regex.c.
946 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
947 realloc.c: automake distributes these files already.
949 2003-09-12 Gary V. Vaughan <gary@gnu.org>
951 Replace the xstrzdup code by importing the xstrndup module from
952 CVS gnulib, along with its dependencies: strndup and strnlen:
954 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
955 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
957 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
958 gnulib/config/strndup.m4: Ditto wrt strndup.
959 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
961 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
962 However, contrary to gnulib, we install xstrndup.h.
963 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
964 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
965 is an artifact of the old m4 portability layer.
966 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
967 * m4/system_.h: Include xstrndup.h.
968 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
970 2003-09-11 Gary V. Vaughan <gary@gnu.org>
972 Reimport the latest xalloc module from CVS gnulib, and adjust the
973 m4 sources to take advantage of xalloc xfree. Also create a new
974 macro DELETE with the same semantics as the old m4 XFREE macro,
975 and carefully tweak callers:
977 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
979 * m4/utility.c (xfree): Removed. This function is now supplied by
981 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
982 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
983 * m4/symtab.c (m4_symtab_create): Ditto.
984 * m4/system_.h: Removed XFREE redefine.
985 (DELETE): New macro with same functionality as the original m4
986 XFREE macro, but based on xalloc.h now. Changed all callers.
987 * src/main.c (main): Use XMALLOC macro.
988 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
990 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
992 2003-09-10 Gary V. Vaughan <gary@gnu.org>
994 Import the xalloc module from CVS gnulib, along with its
995 dependencies: exitfail, malloc and realloc. We had different
996 semantics for our XFREE and a function xfree() not supplied by
997 gnulib, so also a bit of work to keep everything running
1000 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
1001 (gl_XALLOC): Use gnulib equivalents.
1002 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
1003 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
1004 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
1005 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
1007 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
1008 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
1009 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
1011 (pkgincdir): Removed. Use pkgincludedir instead.
1012 * m4/m4private.h (XFREE): xfree already checks for NULL.
1013 * m4/system_.h: Use xalloc module, and remove macros already
1014 supplied by xalloc.h.
1015 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
1016 moved the old definition from m4/xmalloc.c to here for now.
1018 2003-09-09 Gary V. Vaughan <gary@gnu.org>
1020 Import the error and progname modules from CVS gnulib. Our old
1021 error.c subsumed the functionality of both, so a little adjustment
1022 was required to accomodate the split in sources. Also added more
1023 wrapper macros to choose between a system installed error.h or our
1024 shipped gnulib error module:
1026 * m4/error.c, m4/error.h: Removed.
1027 * m4/Makefile.am: Adjust.
1028 (pkgincdir): Removed. Use pkgincludedir instead.
1029 * m4/module.h, src/main.c: Don't include `m4/error.h'.
1030 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
1032 * gnulib/m4/progname.c: Imported from CVS gnulib.
1033 * gnulib/m4/progname.h: Ditto.
1034 * src/main.c: Adjust to use progname module.
1035 * gnulib/m4/error.c: Imported from CVS gnulib.
1036 * gnulib/m4/error_.h: Ditto.
1037 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
1038 if appropriate, and link a local error.h if the system version is
1040 (libgnu_la_SOURCES) Add progname module sources.
1041 * gnulib/config/error.m4: Imported from CVS gnulib.
1042 * gnulib/config/strerror_r.m4: Ditto.
1043 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
1044 to have ERROR_H for Makefile substitutions and tell system.h
1045 whether the system error.h should be used, or a locally installed
1047 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
1049 2003-09-09 Gary V. Vaughan <gary@gnu.org>
1051 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
1052 s/gettext_.h/gettext.h/.
1054 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
1055 automake have been fixed.
1057 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
1058 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
1059 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
1060 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
1062 2003-09-09 Gary V. Vaughan <gary@gnu.org>
1064 The gnulib obstack module requires the gnulib gettext module for
1065 systems that do not have GNU gettext installed. Because we use
1066 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
1067 that directory incase it clashes with the system gettext.h. This
1068 delta uses gettext_.h and extra rules in the Makefile to make a
1069 link to gettext.h when needed:
1071 * Makefile.am (auxdir): Removed. No longer used.
1072 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
1073 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
1075 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
1076 Makefile based build.
1077 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
1078 of the macros are kept.
1079 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
1080 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
1081 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
1082 distributes these automatically.
1083 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
1084 warning from automake-1.7a.
1085 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
1086 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
1088 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
1089 wrt. m4_FUNC_OBSTACK.
1090 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
1091 wrt. m4_sys_STACKOVF.
1092 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
1093 wrt. _m4_LIB_GMP, m4_LIB_GMP.
1094 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
1095 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
1097 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
1098 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
1099 gettext.h link on deficient systems.
1100 (pkginc_HEADERS): Mention $(GETTEXT_H).
1101 (EXTRA_HEADERS): Mention gettext.h.
1102 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
1103 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
1104 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
1105 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
1106 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
1107 gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
1108 gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
1109 gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
1110 gnulib/config/po.m4, gnulib/config/progtest.m4,
1111 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
1112 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
1114 2003-09-05 Gary V. Vaughan <gary@gnu.org>
1116 We can't mirror the gnulib directory structure here, since we need
1117 to be able to eg. `#include <m4/obstack.h>' from our source files,
1118 which is much easier if the local obstack.h is created in a
1119 directory named m4. Rather than trying to symlink everything into
1120 the m4 directory, now we build a libtool convenience library from
1121 the sources we get from gnulib and link that with libm4.la:
1123 * gnulib/config/extensions.m4: Imported from CVS gnulib.
1124 * gnulib/config/unlocked-io.m4: Ditto.
1125 * gnulib/m4/unlocked-io.h: Ditto.
1126 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
1127 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
1128 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
1129 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
1130 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
1131 * m4/Makefile.am: Adjust.
1132 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
1133 macros we redistribute.
1134 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
1135 library among others.
1136 (GNULIB_SRCS, GNULIB_MACROS): Removed.
1137 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
1138 * config/m4-obstack.m4: Adjust.
1139 * po/POTFILES.in: Adjust.
1140 * configure.ac: Reformatting. Call newly imported gnulib macros.
1141 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
1142 bogus calls of `#include "m4.h"'.
1143 * Makefile.am: INCLUDES has been deprecated in favour of
1145 * m4/Makefile.am: Ditto.
1146 * modules/Makefile.am: Ditto.
1147 * src/Makefile.am: Ditto.
1149 2003-09-05 Gary V. Vaughan <gary@gnu.org>
1151 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
1153 2003-09-04 Gary V. Vaughan <gary@gnu.org>
1155 Migrate the obstack support into the gnulib directories for easy
1156 synchronisation with upstream files in gnulib:
1158 * config/gnu-obstack.m4: Moved from here...
1159 * config/m4-obstack.m4: ...to here.
1160 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
1161 * m4/obstack.c, m4/obstack_.h: Moved from here...
1162 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
1163 * po/POTFILES.in: Adjust.
1164 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
1165 * m4/Makefile.am: Add a whole new section to link the obstack
1166 sources from the gnulib tree if necessary.
1167 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
1169 * config/m4-obstack.m4: Rewrite as a wrapper for
1170 gnulib/m4/obstack.m4.
1172 2003-09-04 Gary V. Vaughan <gary@gnu.org>
1174 GNU M4 currently builds with a number of files adapted from
1175 upstream sources. Recently the gnulib project on savannah.gnu.org
1176 has pulled together a great many of these externally maintained
1177 files. This delta is the beginnings of isolating those files
1178 maintained in gnulib to make it easy to synchronise M4 with the
1179 upstream files prior to releases.
1181 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
1183 (SUBDIRS): Added new gnulib subdirectory.
1184 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
1185 * config/stdbool.m4: Moved from here...
1186 * gnulib/m4/stdbool.m4: ...to here.
1187 * m4/stdbool_.h: Moved from here...
1188 * gnulib/lib/stdbool_.h: ...to here.
1189 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
1191 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
1192 code to work with new stdbool_.h location.
1193 (gnulib_srcdir): New.
1195 2003-09-04 Gary V. Vaughan <gary@gnu.org>
1197 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
1198 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
1200 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
1201 (EXTRA_DIST): Use it.
1203 * bootstrap: CVS autoreconf leaves file droppings. Remove
1204 aclocal.m4t incase autoreconf doesn't.
1206 2003-08-29 Gary V. Vaughan <gary@gnu.org>
1208 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
1209 the other gnulib imports, renamed to m4/obstack_.h.
1210 * m4/obstack.c: Updated from CVS gnulib.
1211 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
1212 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
1213 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
1214 about vpath already, and $top_srcdir upsets CVS Automake, so the
1215 $top_srcdir reference was removed.
1217 * m4/system-h.in: For consistency with the gnulib imports, renamed
1219 * m4/Makefile (EXTRA_HEADERS): Adjust.
1220 * configure.ac (AC_CONFIG_FILES): Adjust.
1222 * m4/stdbool_.h: New file from gnulib for systems without their
1224 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
1225 * config/stdbool.m4: New file. Macros from gnulib for same.
1226 * configure.ac: Use it.
1228 2003-08-27 Gary V. Vaughan <gary@gnu.org>
1230 * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'`

1277 * src/main.c: Ditto.
1278 * src/stackovf.c: Ditto.
1280 * config/gmp.m4 (M4_AC_LIB_GMP): Use AC_INCLUDES_DEFAULT:
1281 ac_default_headers is an autoconf internal variable.
1282 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
1283 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
1285 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
1286 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
1289 2003-08-15 Gary V. Vaughan <gary@gnu.org>
1291 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
1293 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
1294 possible or faking one with a typedef. Changed all callers.
1296 2003-08-15 Gary V. Vaughan <gary@gnu.org>
1298 Still cleaning up the users' module API, by taking out the stuff
1299 that isn't used by any existing modules, and moving specialised
1300 functions out of libm4 and into the module they are used by.
1302 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
1303 * m4/utility.c (m4_skip_space): ...to here the home of its only
1304 use, made static and renamed to `skip_space'. Changed all
1306 * m4/m4module.h (m4_expand_ranges): Removed prototype.
1307 * m4/utility.c (m4_expand_ranges): Moved definition from here...
1308 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
1310 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
1312 * modules/gnu.c (builtin_syntax): Import and use in this
1313 builtin implementation.
1314 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
1316 * m4/macro.c (trace_flush): Except here where the macro is now
1318 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
1319 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
1321 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
1322 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
1324 2003-08-14 Gary V. Vaughan <gary@gnu.org>
1326 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
1327 compiler based AC_CHECK_HEADER that was introduced in
1329 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
1330 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
1331 * configure.ac: Use renamed M4_AC_LIB_GMP.
1333 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
1334 macro that requires arguments! This stops the shell's bad
1335 substitution error at configure time.
1337 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
1338 variables to the testsuite shell. Set the value of USE_GMP so
1339 that the gmp test will run!
1340 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
1342 2003-08-11 Gary V. Vaughan <gary@gnu.org>
1344 Libltdl already has an excellent mechanism for accessing C symbols
1345 in modules. Lets use that! Remove all the exporting cruft and
1346 just use lt_dlsym in conjunction with a few conventions to
1347 simplify module writers' jobs. Also removed the table address
1348 caching code and otherwise simplified the module loader quite a
1349 bit. To access exported symbols in other modules, first the
1350 exporting module must name the symbols <modname>_LTX_<symname>,
1351 and the importing module must define a function type called
1352 <symname>_func. The importer then adds
1353 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
1354 that wishes to call out to the exported functions. Care must be
1355 taken that <symname> is non-NULL in the importing module incase
1356 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
1357 definition was in the importers source. Study
1358 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
1359 m4_module_import will attempt to automatically load a module
1360 required for symbol access if it is not loaded already.
1362 * TODO: Removed the items fixed in this delta.
1363 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
1365 * m4/ltdl.h (lt_dlhandle_find): Declare it.
1366 * m4/module.c (m4_module_unload): Use it.
1367 * src/freeze.c (reload_frozen_state): Ditto.
1368 * m4/m4module.h (m4_export): Deleted. Removed all references.
1369 (M4_MODULE_IMPORT): New user convenience macro for importing
1370 arbitrary symbols from other modules.
1371 * m4/module.c (m4_module_import): New function to service
1372 M4_MODULE_IMPORT macro.
1373 (module_data): Removed. Looking up the tables on demand with
1374 lt_dlsym, rather than caching their addresses here simplifies the
1376 (m4_get_module_builtin_table, m4_get_module_macro_table):
1377 Removed. Changed all callers.
1378 (set_module_macro_table, set_module_builtin_table): Renamed to
1379 install_macro_table and install_builtin_table respectively, and
1380 simplified now that the cache is no more.
1381 * modules/gnu.c (builtin_symbols): Use this new mechanism to
1382 import m4_dump_symbols from the m4 module.
1383 (builtin_esyscmd): Likewise for m4_set_sysval and
1385 * modules/m4.c (m4_export_table): Removed. Functions are
1386 addressed with the new mechanism which doesn't need this.
1387 (m4_set_sysval): New exported accessor function to prevent
1388 problems with variable access on inferior architectures.
1389 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
1390 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
1391 that we can have some type safety.
1392 * modules/modtest.c (export_test): C level exported function for
1393 testing the new import mechanism.
1394 * modules/import.c: New file for the import end of the test.
1395 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
1396 * tests/modules.at: New test cases for intermodule symbol
1399 2003-08-07 Gary V. Vaughan <gary@gnu.org>
1401 * m4/m4module.c (m4_string): Moved from here...
1402 * m4/m4private.c (m4_string): ...to here.
1404 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
1406 2003-07-29 Gary V. Vaughan <gary@gnu.org>
1408 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
1409 already available to module writers through
1410 m4_{get,set}_nesting_limit_opt(), so moved from here...
1411 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
1412 (m4_create): Use it.
1414 2003-07-28 Gary V. Vaughan <gary@gnu.org>
1416 Aside from auditing path.c for m4module.h api obfuscation, this
1417 delta introduces the concept of private struct members in opaque
1418 data types to GNU m4: See the STYLE file for details.
1420 * TODO: Remind ourselves that a rewrite of path.c is needed.
1421 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
1423 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
1424 here and renamed. These type definitions are for internal api use
1425 only. Changed all callers.
1426 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
1428 * m4/path.c (search_path_env_init, search_path_add): ...to here
1429 and renamed. These calls were never used outside this file.
1430 Changed all callers.
1431 (dirpath): Moved functionality of this static declaration...
1432 * m4/m4private.h (struct m4): ...to this new internal only
1433 search_path field. Changed all callers.
1434 (m4__get_search_path): Added new internal api accessor.
1435 * m4/path.c (m4_search_path_info_new): Removed. Not used.
1436 (m4_include_init): Removed...
1437 * m4/m4.c (m4_create): ...because the new m4 field is now
1439 (m4_delete): Recycle search_path memory.
1440 * src/main.c (main): Don't call m4_include_init now that it's
1442 * doc/STYLE: Document convention for private fields in opaque
1445 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1447 Sometimes exporting the address of a symbol from a module isn't
1448 enough for other modules to call that symbol correctly. If
1449 custom data types are used for function parameters, they need to
1450 be known to the caller. This change introduces the concept of
1451 $(prefix)/include/modules/$(modulename).h to declare those
1452 structures. Also we move m4_dump_symbols from libm4 to the m4
1453 module to show this concept in action.
1455 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
1456 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
1457 exporting data structures from modules/m4.c.
1458 * modules/m4.c, modules/gnu.c: Include it.
1459 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
1460 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
1462 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
1464 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
1465 ...to here, with slight renaming.
1466 (m4_export_table): Prototype and add m4_dump_symbols.
1467 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
1468 definition of m4_dump_symbols.
1469 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
1470 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
1472 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1474 Create an export table in modules/m4.c in readiness for beefing up
1475 the module loader to track module exports and imports.
1477 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
1478 * m4/debug.c (m4_debug_flush_files): Moved...
1479 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
1480 * modules/gnu.c (builtin_esysval): Use it.
1481 * m4/m4module.h (m4_export): New type for declaring module symbols
1483 * modules/m4.c (m4_export_table): List symbols exported from this
1484 module for use by other modules.
1486 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1488 An experiment: There is loads of code in libm4 which should be in
1489 the m4 module, but is also used by another module. Just because
1490 some linkers won't cope with calls across dynamic runtime loaded
1491 objects I initially left the code in libm4. It will tidy the
1492 module api immensely if this code moves to the right place, I just
1493 need to remember to invent a suitable calling mechanism at some
1494 point. For now, only modules that are statically linked and
1495 preloaded will get this treatment, so the only platforms that will
1496 break are those that require all symbols to be resolved at link
1499 * TODO: Reminder that what I am doing could reduce portability
1500 unless I do something more robust later.
1501 * m4/m4module.h (m4_sysval): No longer exported from libm4.
1502 * m4/utility.c (m4_sysval): No longer declared in libm4.
1503 * modules/Makefile.am: Reformatting.
1504 * modules/m4.c (m4_sysval): Declare it at place of use.
1505 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
1507 2003-07-23 Gary V. Vaughan <gary@gnu.org>
1509 * m4/m4module.h: Reformatting and rearranging lines a bit.
1510 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
1512 (m4_call_macro, m4_expand_input): Renamed...
1513 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
1515 (m4_expansion_level, m4_process_macro): Moved...
1516 * m4/macro.c (expansion_level, process_macro): ...to here, and
1519 * m4/m4module.h (program_name): Not used by modules at all, so
1521 * src/main.c (program_name): ...to here.
1522 (print_program_name): Renamed...
1523 (print_program_name_CB): ...to conform to the STYLE guide.
1525 2003-07-23 Gary V. Vaughan <gary@gnu.org>
1527 More refactoring of the m4module.h API. Replace #defines with an
1528 enum, and move non-public functions out of the public API.
1530 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
1532 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
1533 * m4/debug.c (m4_debug, trace): Moved...
1534 * m4/m4private.h (struct m4): ...to fields of this struct.
1535 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
1537 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
1538 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
1539 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
1540 * m4/m4module.h (m4_context_field_table): Add entries for new
1541 debug_file and trace_messages fields.
1542 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
1543 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
1544 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
1545 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
1546 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
1547 (m4_is_debug_bit): New macro to simplfy checks against the debug
1549 (m4_trace_format, m4_trace_header, m4_trace_flush)
1550 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
1552 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
1553 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
1554 * m4/macro.c (trace_format, trace_header, trace_flush)
1555 (trace_prepre, trace_pre, trace_post): ...to these newly static
1556 functions, since they are only ever used from this file. Changed
1559 2003-07-17 Gary V. Vaughan <gary@gnu.org>
1561 Change the macros for checking syntax so that matching against
1562 multiple possible syntax classes can be done with a single
1563 comparison some of the time. The various classes are now bits of
1564 an int that can be checked with bitwise logic operators.
1566 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
1567 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
1568 (M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)
1569 (M4_SYNTAX_ASSIGN, M4_SYNTAX_ALPHA, M4_SYNTAX_NUM)
1570 (M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)
1571 (M4_SYNTAX_ECOMM): Replaced #defines with an enum.
1572 (M4_SYNTAX_ALNUM): Removed. Changed all callers.
1573 (M4_IS_IGNORE, M4_IS_OTHER, M4_IS_SPACE, M4_IS_OPEN, M4_IS_CLOSE)
1574 (M4_IS_COMMA, M4_IS_DOLLAR, M4_IS_ACTIVE, M4_IS_ESCAPE)
1575 (M4_IS_ASSIGN, M4_IS_ALPHA, M4_IS_NUM, M4_IS_LQUOTE, M4_IS_RQUOTE)
1576 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
1577 Replace all calls with invocations of these...
1578 (m4_is_syntax, m4_has_syntax): ...New macros.
1579 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
1580 is no longer required with new macros. Changed all callers.
1582 2003-07-15 Gary V. Vaughan <gary@gnu.org>
1584 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
1585 values are returned as part of the internal interface, so they
1587 * m4/private.h: ...to here.
1588 * m4/macro.c (expand_token): Check for out of range
1589 m4_peek_input() results before looking up in the syntax table.
1590 (collect_arguments): Ditto.
1592 * NEWS: Note `$' syntax class.
1594 2003-07-08 Paul Eggert <eggert@twinsun.com> and
1595 Gary V. Vaughan <gary@gnu.org>
1597 Conform to POSIX if the POSIXLY_CORRECT environment is set.
1598 --traditional `define' now smashes all the definitions.
1600 * NEWS: Explain this.
1601 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
1602 (Extensions): Explain that extensions that are incompatible with
1603 POSIX are disabled if POSIXLY_CORRECT is set.
1604 (Incompatibilities): Remove.
1605 (Define, Other Incompat): Explain difference
1606 between GNU and POSIX behavior of define, pushdef, popdef.
1607 * m4/m4.c (m4_get_posixly_correct_opt): New undef.
1608 * m4/m4module.h (m4_context_opt_bit_table): Add POSIXLY_CORRECT entry.
1609 * m4/m4private.h (M4_OPT_POSIXLY_CORRECT_BIT): New macro.
1610 (m4_get_posixly_correct_opt): New macro.
1611 * m4/m4macro.c (m4_process_macro): Disable $10, $abc etc. if
1613 * modules/m4.c (builtin_functions): defn now takes any number of args.
1614 (builtin_define): Smash all the definitions if
1616 (builtin_defn)): Allow any number of arguments.
1617 (builtin_undivert): Do not allow nonnumeric arguments
1619 * src/main.c (main): Set posixly-correct behavior if either
1620 POSIXLY_CORRECT is set, or if -G is given.
1621 * tests/builtins.at: New test for smashed definitions.
1623 2003-06-27 Gary V. Vaughan <gary@gnu.org>
1625 * doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
1626 * m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
1627 not to slow the parser down.
1628 (M4__IS_STRING): New macro to test string syntax class membership.
1629 * m4/syntax.c: Adjust docucomment.
1630 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
1631 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
1632 * m4/input.c (init_builtin_token): Comment typo.
1633 (m4__next_token): Comment typo.
1634 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
1635 by using the new M4__IS_STRING macro.
1636 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
1637 variable references in macro expansions.
1639 * doc/m4.texinfo (Eregexp and Regexp): Typo.
1640 (Epatsubst and Patsubst): Typo.
1643 2003-06-26 Gary V. Vaughan <gary@gnu.org>
1645 Move the global variables that pertain to syntax to a new `struct
1646 m4_syntax_table', and then add one of these to `struct m4'. The
1647 ripple effect through the code to both change formerly global
1648 references, and make sure a suitable context is available in
1649 lexical scope is disproportionately large compared to the size of
1650 the change proper. This change is a large part of decoupling
1651 syntax.c from the rest of the code that uses it.
1653 * m4/m4private.h (struct m4): Add a syntax field.
1654 * m4/m4.c (m4_create): Initialise it,
1655 (m4_delete): Recycle it.
1656 (m4_get_symtab): Remove hand coded version...
1657 (m4_get_symbol_table): ...and generate this with cpp. Changed all
1659 * m4/m4module.h (m4_context_field_table): Add an extra field so we
1660 can generate m4_get_symbol_table. Add a new row for
1661 m4_get_syntax_table.
1662 (M4SYNTAX): Syntactic sugar for module writers.
1663 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
1664 (m4_syntax_table): New home for syntax related formerly global
1666 * m4/m4private.h (struct m4_syntax_table): Define it.
1667 * m4/input.c (m4_input_init): Initialisation of these formerly
1668 global variables moved...
1669 * m4/syntax.c (m4_syntax_create): ...to here.
1670 * m4/input.c (m4_input_exit): And similarly, recycling of the
1671 memory used by those values moved...
1672 * m4/syntax.c (m4_syntax_delete): ...to here.
1673 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
1674 Moved to m4/m4private.h.
1675 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
1676 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
1677 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
1678 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
1679 objects. Changed all callers that used to directly access the
1681 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
1682 Removed and incorporated into m4_syntax_table structure.
1683 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
1684 * m4/syntax.c (m4_set_syntax): Now returns an error status,
1685 instead of requiring a `struct m4' to generate its own errors.
1686 Changed all callers.
1687 * src/main.c (main): Now that the syntax table is initialised as
1688 part of m4_create, we have to manually wipe the syntax entries if
1689 we are about to read a frozen file.
1691 2003-06-26 Gary V. Vaughan <gary@gnu.org>
1693 * doc/STYLE: Added notes on callback naming schemes.
1695 * m4/module.c (m4_set_module_macro_table)
1696 (m4_set_module_builtin_table): Declarations weren't changed when
1697 definitions were renamed on 2003-06-19.
1699 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
1700 neither used nor particularly appropriate since it exposes the
1701 internal workings of the hash module. I haven't yet decided
1702 whether to remove it entirely.
1704 2003-06-20 Gary V. Vaughan <gary@gnu.org>
1706 Two related changes, and a huge knockon effect throughout the
1707 source: Moved the option variables out of global space and into
1708 `struct m4'; made `m4_symtab' a real datatype, so that its api
1709 is not marred passing `struct m4' around just so it can decide
1710 whether to keep traced symbol names or not. Added setters and
1711 getters for the formerly global option variables, and obviously
1712 changed a vast number of functions to take a `struct m4' and use
1713 the getter funcs to find option values.
1715 * m4/utility.c (interactive, sync_output, debug_level)
1716 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
1717 (max_debug_argument_length, warning_status, nesting_limit)
1718 (discard_comments): Removed.
1719 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
1720 (debug_level, max_debug_argument_length, prefix_all_builtins)
1721 (suppress_warnings, discard_comments, interactive, sync_output):
1722 Removed from here...
1723 * m4/m4private.h (struct m4): ...and equivalent fields added to
1725 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
1726 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
1727 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
1728 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
1729 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
1730 macros for the new fields.
1731 * m4/m4module.h (m4_context_field_table)
1732 (m4_context_opt_bit_table): Helper macros used to generate
1733 prototypes, setters and getters for new option fields
1735 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
1736 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
1737 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
1738 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
1739 (m4_get_interactive_opt, m4_get_sync_output_opt)
1740 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
1741 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
1742 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
1743 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
1744 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
1745 setter and getter functions generated by cpp from
1746 m4_context_field_table and m4_context_opt_bit_table, exported as
1747 part of the module api. Changed all callers.
1748 * m4/symtab (struct m4_symtab): Used as the concrete type for
1750 (m4_symtab_create): Allocate and initialise a new struct.
1751 (m4_symtab_apply): New function that works like m4_hash_apply, but
1752 with different callbacks specific to symbol tables. Changed all
1754 (symbol_destroy, arg_destroy, arg_copy): Renamed
1755 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
1756 they have unused parameters for a reason!
1757 (dump_symbol_CB): New callback to dump the contents of a single
1759 (symtob_dump): Rewritten in terms of dump_symbol_CB.
1760 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
1761 Changed all callers.
1762 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
1763 of the contained `m4_symtab' at the `no_gnu_extensions' field.
1764 Although I'm not convinced these semantics are correct, they are
1765 at least consistent with how things were before this delta. Also
1766 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
1768 2003-06-19 Gary V. Vaughan <gary@gnu.org>
1770 Tie down the interface to libm4 some more. Make more structures
1771 opaque to modules by moving them to m4private.h, and writing
1772 setters and getters. To win back the speed penalty for doing this
1773 also wrote macroized versions that do know about structure layout
1774 in m4private.h and #include that file into modules when NDEBUG is
1775 defined at compile time. There are still some accessor macros in
1776 m4private.h that need to go, but that is not necessary to clean
1779 * m4/m4module.h (m4_symbol_type): Moved...
1780 * m4/m4private.h (m4__symbol_type): ...to here.
1781 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
1782 (m4_set_symbol_traced, m4_set_symbol_name_traced)
1783 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
1784 (m4_get_symbol_func, m4_symbol_value_create)
1785 (m4_symbol_value_delete, m4_set_symbol_value_text)
1786 (m4_set_symbol_value_func): New exported api to symbols.
1787 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
1788 and m4_is_symbol_value_func.
1789 * m4/m4module.h: Prototype these guys.
1790 * m4/module.c (m4_set_module_macro_table)
1791 (m4_set_module_builtin_table): Make these static, there is no
1792 reason to pollute the api with them.
1793 * m4/m4private.h: Reformatting.
1794 (m4_get_symtab): Only define when NDEBUG is defined.
1795 (m4_get_symbol_value, m4_get_symbol_traced)
1796 (m4_set_symbol_traced, m4_set_symbol_name_traced)
1797 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
1798 (m4_get_symbol_func, m4_symbol_value_create)
1799 (m4_symbol_value_delete, m4_set_symbol_value_text)
1800 (m4_set_symbol_value_func): Macro implementations of the new
1801 functions when NDEBUG is defined.
1802 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
1803 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
1804 Superceded by the above. All callers changed.
1805 (M4ARG): Removed. This is no longer different to the
1806 m4/m4module.h definition.
1807 * modules/gnu.c, modules/m4.c: Only include m4private.h when
1808 NDEBUG is defined. That way we exercise the same (albeit slower)
1809 api that external modules must use.
1811 2003-06-18 Gary V. Vaughan <gary@gnu.org>
1813 Renamed some of the types and their accessors to make more sense.
1814 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
1815 has a stack of SYMBOL_VALUEs.
1817 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
1818 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
1819 m4_get_symbol_value_type, m4_get_symbol_value_text,
1820 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
1821 Changed all callers.
1822 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
1823 (m4_get_token_type): Renamed
1824 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
1825 to the internal api.
1826 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
1828 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
1829 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
1830 (m4__token_type): Moved here from m4module.h.
1831 (m4__next_token): Renamed from m4_next_token.
1832 * m4/symtab.c: Removed some of the parameterised macro support
1833 functions for modularisation later.
1834 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
1835 m4_hash_dup to perform a true deep copy of the SRC.
1836 (arg_copy): Callback for m4_symbol_value_copy.
1837 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
1838 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
1839 m4_get_symbol_value_func. Changed all callers.
1841 2003-06-18 Gary V. Vaughan <gary@gnu.org>
1843 Tidy up style of hash.[ch] in accordance with doc/STYLE.
1845 * m4/hash.c: Internal symbol renaming and formatting.
1846 (m4_hash_dup): New function to facilitate deep copies of hash
1848 (m4_hash_apply_func): Returns a void* now, which is a richer type
1849 for returning exceptions (NULL means keep going).
1850 (m4_hash_apply): Ditto.
1851 * m4/hash.h: Declare exported symbols with an explicit extern.
1854 2003-06-17 Gary V. Vaughan <gary@gnu.org>
1856 Still refactoring furiously. This delta represents a change in
1857 semantics to symtab.c. Instead of building temporary m4_tokens
1858 in the caller, and copying fields in the methods, we now create
1859 the actual m4_token for hashing in the caller so the methods just
1860 slot them in directly. Also, this means that we don't lookup a
1861 symbol and get back an allocated but VOID token to copy fields
1862 into, we create the token we want to push and pass that to
1863 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
1864 a few other small changes to stop knowledge of the implementation
1865 of symtab.c leaking out into other files.
1867 * m4/macro.c (expand_argument): Comment typo corrected.
1868 * m4/symtab.c (symtab_fetch): New function to fetch the address of
1870 (m4_symbol_pushdef): Take an extra value parameter and use this
1871 directly as the new top of the value stack. All callers changed
1872 to build a token and pass responsibility for memory in, rather
1873 than copying as we used to.
1874 (m4_symbol_define): Also use the new value parameter directly as a
1875 replacement for the top of the value stack. All callers changed
1876 to build a token as above.
1877 (m4_set_symbol_traced): New function to set the traced bit on the
1878 named symbol, creating it if necessary.
1879 (symbol_popval): The guts of the old m4_symbol_popdef.
1880 (m4_symbol_popdef): Use it.
1881 * m4/builtin.c (m4_symbol_set_token): Removed,
1882 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
1884 * m4/module.c (m4_set_module_builtin_table)
1885 (m4_set_module_macro_table): ...with these more orthogonal
1887 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
1888 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
1890 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
1891 (m4_arg_signature_parse): Moved...
1892 * m4/symtab.c: ...to here.
1893 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
1894 screw something up. Moved...
1895 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
1896 actually does a proper deep copy of source to dest.
1898 2003-06-16 Gary V. Vaughan <gary@gnu.org>
1900 Further refactoring to stabilise the module API. Renaming some
1901 functions for orthogonality, and judicious definition migration to
1902 move things out of the set of exported symbols.
1904 * doc/STYLE: New file. Notes on coding style.
1905 * m4/m4module.c: Updated bitrotted docucomment at the top of the
1907 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
1908 m4_get_module_name, m4_get_module_builtin_table,
1909 m4_get_module_macro_table which are verb phrases. Changed all
1911 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
1913 * m4/module.c (m4_set_module_builtin_table)
1914 (m4_set_module_macro_table): ...here, and renamed. Changed all
1916 * m4/m4module.c (m4_module_data): This...
1917 * m4/m4private.c (struct m4_module_data): ...and this...
1918 * m4/module.c (module_data) ...consolidated here and no longer
1919 exported. Changed all callers.
1921 2003-06-16 Gary V. Vaughan <gary@gnu.org>
1923 Begin work on lifting the curse of the global variables. To start
1924 with create a `struct m4' context container, and replace
1925 `m4__symtab' with `context->symtab' throughout. This means
1926 initialising a context container in main, and adjusting many
1927 functions between main and the module entry points so that the
1928 container gets passed through. It would have been nice to
1929 defer this until after 1.5, but it has a major effect on the
1930 user's module writing ABI, so it needs to be addressed now - at
1931 least in the areas that impact the ABI. An interrelated change
1932 in the symtab API removes the dependency on a global symbol table,
1933 and instead focuses on a passed table (from the context
1936 * TODO: Reminders for finishing context functionality.
1937 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
1938 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
1939 global variables and eventually allow m4 to be reentrant.
1940 * m4/m4private.h (m4): Define the new structure here...
1941 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
1942 don't carry the overhead of a function call.
1943 * m4/m4module.h: Prototype extern functions from m4/m4.c.
1944 (m4): Declare type for new struct m4 objects.
1945 (M4SYMTAB): User macro to ease finding the symbol table for the
1946 current context for module developers.
1947 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
1949 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
1950 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
1951 (m4_call_macro, m4_dump_symbols, m4_expand_input)
1952 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
1953 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
1954 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
1955 m4* context parameter. Changed definitions and all callers.
1956 (m4_symtab): Alias for m4_hash to decouple the
1957 m4_symtab api from m4_hash.
1958 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
1960 (m4_symtab_create): New function to return an initialised
1962 (m4_symtab_delete): New function to delete an m4_symtab's memory.
1963 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
1964 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
1965 instead of simply using the global m4__symtab. Changed
1966 definitions and all callers.
1967 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
1968 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
1969 * src/main.c (main): Create a context and use that instead of the
1970 former global m4__symtab.
1972 2003-06-13 Gary V. Vaughan <gary@gnu.org>
1974 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
1975 to the callback. Callbacks should not need to hardcode the
1976 hashtable they are working from, nor should we have to waste the
1977 userdata parameter to pass the table in.
1978 * m4/hash.h (m4_hash_apply_func): Require the initial table
1980 * m4/symtab.c (symtab_destroy): Use the passed table instead
1981 of hardcoding m4__symtab.
1982 (m4_symbol_popdef): Don't use the userdata parameter to pass the
1983 table to arg_destroy.
1984 (arg_destroy): Use the hash parameter, ignore userdata.
1985 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
1987 (traceon, traceoff): Call set_trace with the extra initial
1990 2003-06-13 Gary V. Vaughan <gary@gnu.org>
1992 More refactoring to stabilise the module api, this time for
1993 symtab.c. Additionally, start to pay attention to function names
1994 that don't contain a verb like they should.
1996 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
1997 wrapper for m4_hash_apply to decouple the symtab module from the
1999 (m4_symbol_builtin, m4_symbol_macro): Renamed to
2000 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
2002 (m4_symbol_delete): Create a macro version to save a function
2004 (m4_token_t, m4_data_t): These violate the POSIX reserved
2005 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
2007 (m4_token_type): Renamed to m4_token_get_type.
2008 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
2009 (m4_symtab_exit): Removed from the exported module
2011 * m4/m4private.h (m4__symtab, m4__symtab_init)
2012 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
2013 renamed and added to the internal api. Changed all callers.
2014 (m4_symtab_apply): A faster macro version of the function for
2015 users of the internal api.
2016 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
2017 symbol_destroy and arg_destroy.
2018 (symtab_debug): Added a prototype.
2019 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
2020 so that callers in this file get the faster macro versions from
2023 2003-06-12 Gary V. Vaughan <gary@gnu.org>
2025 Refactoring modules to rationalise the API into an external
2026 documented (eventually!) API for use by modules in the `m4_'
2027 namespace declared in m4/m4module.h, an internal API between the
2028 source files we ship (including our shipped modules) in the `m4__'
2029 namespace declared in m4/m4private.h and making the rest as
2030 cohesive as possible with liberal use of the `static' keyword.
2031 This change represents an audit to m4/module.c along these
2034 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
2035 Removed. No longer used.
2036 (m4_module_close): Removed prototypes.
2037 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
2038 from the exported module api...
2039 * m4/m4private.h (m4__module_init, m4__module_open)
2040 (m4__module_exit): ...and renamed and added to the internal api.
2041 Changed all callers.
2042 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
2043 Centralised definitions after renaming...
2044 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
2045 (M4_FINISH_SYMBOL): ...and removing from here.
2046 (m4_module_dlerror, m4_module_remove, m4_module_close)
2047 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
2048 module_remove, module_close and caller_id.
2049 (MODULE_SELF_NAME): New macro to make reporting self errors
2051 (m4_module_load, module_close, module_remove): Use it.
2052 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
2054 * src/main.c (main): Use it.
2056 2003-06-12 Gary V. Vaughan <gary@gnu.org>
2058 * README: Remove references to --enable-changeword, which has been
2059 removed from the code.
2061 2003-06-11 Gary V. Vaughan <gary@gnu.org>
2063 Getting rid of the annoying bug with configure --enable-debug,
2064 which spewed -e: command not found errors. This was an interaction
2065 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
2066 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
2067 branch-1-5) to get the full fix.
2069 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
2070 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
2071 and then use the probed value of $SED.
2072 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
2073 this, it messes up the AC_REQUIRE stack.
2075 2003-06-10 Gary V. Vaughan <gary@gnu.org>
2077 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
2078 the destroy callback.
2079 (m4_arg_destroy): Use the hash address to free the hash node key
2082 2003-06-06 Gary V. Vaughan <gary@gnu.org>
2084 First cut at formal parameters in macros.
2086 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
2087 * m4/xstrzdup.c: New file.
2088 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
2089 associative array of parameter names to details.
2090 (m4_symbol_token): Capture macro names with parameter lists.
2091 (m4_arg_signature_parse): And build an associative array to hang
2092 from the symbol structure to map names to details.
2093 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
2094 m4_hash_resize idiom. Now that we potentially add a little hash
2095 table to many of the entries in the symbol table, added an extra
2096 arg to set the initial size. Changed all callers.
2097 (m4_hash_apply): New function that is basically a generalised
2099 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
2100 all callers to call m4_hash_apply instead.
2101 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
2102 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
2103 m4_arg_signature association that might be attached to the symbol,
2104 * m4/hash.h (m4_hash_apply_func): Replacement type for...
2105 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
2106 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
2108 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
2109 (M4_IS_IDENT): Detect characters that can be safely used in
2111 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
2112 * m4/macro.c: Corrected grammar in some comments. Use `token'
2113 rather than `td' for m4_token variables.
2114 (m4_process_macro): If we find a dollar followed by some
2115 M4_IS_IDENT characters, replace that with the contents of the argv
2116 entry with offset stored in the m4_token_arg associated with the
2117 collected identifier.
2119 2003-06-05 Gary V. Vaughan <gary@gnu.org>
2121 Begin preparations for supporting formal parameters in m4 macros.
2123 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
2124 the details of a formal parameter.
2125 (m4_token): Add an arg_signature member to hold a hash table for
2126 looking up formal parameters.
2127 * m4/input.c: Update more bitrotted comments.
2128 (m4_push_builtin): Initialise arg_signature member.
2129 (init_builtin_token): Copy arg_signature member.
2130 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
2131 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
2133 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
2134 (m4_macro_pushdef, m4_macro_define): ...these, And...
2135 (m4_symbol_token): ...wrapped around this new function, which
2136 vastly simplifies the arguments required by the functions it
2138 Changed all callers.
2140 2003-06-05 Gary V. Vaughan <gary@gnu.org>
2142 * m4/macro.c: Format changes.
2144 2003-06-04 Gary V. Vaughan <gary@gnu.org>
2146 * m4/input.c: Updated various bitrotted comments.
2147 (m4_push_builtin): Just pass the whole m4_token, rather than
2148 extracting all the fields in the caller. This also allows us to
2149 check the token type for consistency.
2150 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
2151 Renamed to builtin_funcs, builtin_peek, builtin_read,
2152 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
2153 the code. Changed all callers.
2154 (struct input_block): Similarly renamed u_m member to u_b, and
2155 changed all callers.
2156 (m4_next_token): Use bzero to initialise the data fields.
2157 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
2159 2003-05-29 Gary V. Vaughan <gary@gnu.org>
2161 These changes were necessary to get m4 to build on my iBook
2162 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
2163 (GCC) 3.1 20020420 (prerelease)":
2165 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
2166 inclusion of module loader headers.
2167 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
2168 * m4/Makefile.am: Ditto.
2169 (libm4_la_LIBADD): Added $(LTLIBINTL).
2170 * m4/utility.c (program_name): Removed declaration in favour of
2171 the one already in error.c!
2172 * m4/m4module.h (program_name): Define to program_invocation_name
2173 when using GNU C library. Use an explicit extern declaration.
2174 (interactive, sync_output, debug_level, hash_table_size)

2184 (m4_current_line, m4_current_diversion, m4_output_current_line):
2185 Don't rely on default, use an explicit extern.
2186 * m4/error.h (error, error_at_line, error_print_progname)
2187 (error_message_count, error_one_per_line): Ditto.
2188 * m4/ltdl.c: Update from CVS libtool.
2190 * commit: Update from CVS cvs-utils.
2192 2002-11-04 Akim Demaille <akim@epita.fr>
2194 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
2196 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
2198 2002-11-04 Akim Demaille <akim@epita.fr>
2200 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
2202 2002-11-04 Akim Demaille <akim@epita.fr>
2204 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
2205 used as `external', and Libtool 1.4.3.
2207 (LTLIBOBJS): Don't play with it.
2209 * Makefile.am (SUBDIRS): Remove intl.
2210 (ACLOCAL_AMFLAGS): Add -I config.
2211 (EXTRA_DIST): Add config/config.rpath.
2214 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
2216 2002-05-29 Gary V. Vaughan <gary@gnu.org>
2218 Preparations for refactoring syntax tables to allow reverse
2219 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
2220 speed of normal lookups in an array of unsigned short.
2222 * m4/input.c (single_quotes, single_comments, use_macro_escape):
2224 * m4/m4private.h (m4__single_quotes, m4__single_comments,
2225 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
2226 is for internal symbols which unavoidably pollute the global
2227 namespace, but are not published APIs.
2228 Adjusted all callers.
2229 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
2230 m4_set_comment, m4_set_syntax, set_syntax_internal,
2231 unset_syntax_attribute): Moved from this file...
2232 * m4/syntax.c: New. ...to this file.
2233 Also added an m4_syntax_exit stub for orthogonality.
2234 * src/main.c (main): Use it.
2235 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
2236 * m4/m4module.h: Reformatting. New prototypes.
2238 2002-05-29 Gary V. Vaughan <gary@gnu.org>
2240 * bootstrap (aclocal_apiversion): The aclocal apiversion is
2241 distinct from the automake release number (in that the apiversion
2242 apparently has no micro-version-component).
2243 (aclocal_apilibdir): Use it.
2245 2002-05-28 Gary V. Vaughan <gary@gnu.org>
2247 * m4/hash.c (m4_hash_resize): New function.
2248 * m4/hash.h: Add prototype.
2249 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
2250 benchmarking to find a good value for, say, autoconf. This is
2251 already a little quicker than before for me.
2253 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
2254 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
2256 * m4/hash.h: Adjust prototypes.
2258 2002-01-22 Akim Demaille <akim@epita.fr>
2260 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
2262 * tests/Makefile.am (package.m4): New.
2263 * tests/atlocal.in: Adjust to CVS Autotest.
2264 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
2265 * configure.ac: LIBOBJ is a forbidden string.
2266 Simplify AM_INIT_AUTOMAKE invocation.
2267 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
2270 2001-10-19 Akim Demaille <akim@epita.fr>
2272 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
2274 2001-10-19 Akim Demaille <akim@epita.fr>
2276 * m4/input.c (m4_next_token): Display where was opened what is
2279 2001-10-19 Akim Demaille <akim@epita.fr>
2281 * m4/macro.c (expand_argument): Display where was opened what is
2284 2001-10-18 Akim Demaille <akim@epita.fr>
2286 * m4/input.c, modules/m4.c: Formatting changes.
2288 2001-10-17 Gary V. Vaughan <gary@gnu.org>
2290 * bootstrap: s/configure.in/configure.ac/
2292 2001-10-16 Gary V. Vaughan <gary@gnu.org>
2294 * m4/symtab.c (m4_symbol_destroy): This function calls
2295 m4_symbol_popdef, which recycles a symbols memory when the last
2296 definition is popped. Since we were passing the address of the
2297 symbol name found in the symbol table, and it was being removed
2298 partway through m4_symbol_destroy() we were referencing freed
2299 memory for the balance of the function. Now we take a copy of the
2300 symbol name tring and use that as a key into the symbol
2301 table... that way if the original symbol name is freed, the copy
2304 2001-10-13 Akim Demaille <akim@epita.fr>
2306 * m4/ltdl.c: Update.
2308 2001-10-13 Akim Demaille <akim@epita.fr>
2310 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
2311 Don't gettextize internal error messages.
2313 2001-10-13 Akim Demaille <akim@epita.fr>
2315 * tests/macros.at (Arity and defn): New failing test.
2316 (Arity, defn, and freeze): New.
2318 Fix `Arity and defn'.
2320 * m4/input.c (m4_push_macro): Don't forget the arity.
2321 * modules/m4.c (defn): Likewise.
2323 2001-10-13 Akim Demaille <akim@epita.fr>
2325 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
2327 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
2328 (Propagation of traceon, Propagation of --trace): this new file.
2330 2001-10-13 Akim Demaille <akim@epita.fr>
2332 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
2333 interface instead of (name, argc...).
2334 Upon failure, specify which argument was guilty.
2337 2001-10-13 Akim Demaille <akim@epita.fr>
2339 * modules/evalparse.c: Save translators' time: don't translate
2340 internal error messages.
2341 (m4_evaluate): Simplify/normalize error messages.
2342 * doc/m4.texinfo (Eval): Adjust.
2344 2001-10-13 Akim Demaille <akim@epita.fr>
2346 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
2347 where no checking is needed.
2348 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
2349 interface instead of (name, argc...).
2351 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
2354 2001-10-13 Akim Demaille <akim@epita.fr>
2356 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
2357 exclude the builtin name from the count.
2358 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
2359 calling ifelse with a single argument is valid.
2360 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
2361 with 1 and 2 args, mostly to strengthen the test suite.
2363 2001-10-13 Akim Demaille <akim@epita.fr>
2365 * m4/output.c (m4_make_diversion, m4_insert_file)
2366 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
2368 2001-10-12 Gary V. Vaughan <gary@gnu.org>
2370 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
2371 since we call these things builtins in the rest of the code!
2373 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
2375 2001-10-12 Gary V. Vaughan <gary@gnu.org>
2377 Rather than forcing each builtin definition to manage its own
2378 argument range checking, tabulate the maxima and minima for all
2379 builtins in each module. This forces us to consider what the
2380 valid ranges for each builtin should be, and moves the checking
2381 code out of each builtin implementation and into the builtin
2382 caller infrastructure.
2384 * m4/m4module.h (struct m4_builtin): Add argument minima and
2386 * m4/m4private.h (struct m4_token): Reflect them here too.
2387 * m4/input.c (struct input_block): ...and here.
2388 (m4_token_copy): New function for token copying.
2389 (init_macro_token): Copy them from a token to the input stack.
2390 (m4_next_token): Don't forget to initialise them for text
2392 * m4/macro.c (expand_argument): Use m4_token_copy, and also
2393 check argument counts before calling the builtin handler.
2394 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
2395 (m4_symbol_macro): Likewise.
2396 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
2397 parameters. Updated all callers.
2398 (m4_builtin_define): Ditto.
2399 (m4_macro_pushdef, m4_macro_define): Ditto.
2400 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
2401 * modules/evalparse.c: Declare argument counts for defined
2402 builtins and remove explicit calls to m4_bad_argc().
2403 * modules/gnu.c: Ditto.
2404 * modules/load.c: Ditto.
2405 * modules/m4.c: Ditto.
2406 * modules/modtest.c: Ditto.
2407 * modules/mpeval.c: Ditto.
2408 * modules/perl.c: Ditto.
2409 * modules/shadow.c: Ditto.
2410 * modules/stdlib.c: Ditto.
2411 * modules/time.c: Ditto.
2414 2001-10-10 Gary V. Vaughan <gary@gnu.org>
2416 The trace semantics now attach the trace bit to a symbol name.
2417 For as long as a traceon(`foo') is active, calls to foo will be
2418 traced regardless of intervening undefines or module unloads.
2419 Fixed the flag propogation issues differently to the fixes
2420 reverted with the last attempt at nailing down trace:
2422 * m4/m4private.h: This file is not visible outside of the m4
2423 source tree, so I removed all the `M4_' and `m4_' prefixes to save
2424 on typing. Updated all clients.
2425 (m4_token): New typedef contains the fields that need to be passed
2426 around with the low level tokeniser.
2427 (m4_token_data): Removed.
2428 (m4_symbol): Now contains the traced flag again.
2429 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
2430 the trace bit set. This change is contained entirely within this
2431 module and doesn't leak out into the callers. Updated all
2433 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
2434 new fields in m4_token. Updated all clients.
2435 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
2436 that `groks_macro_args' and `blind_if_no_args' flags are retained
2437 when defn() results are passed around in m4 code. Updated all
2439 (m4_builtin_define): Ditto.
2440 (m4_macro_pushdef, m4_macro_define): Ditto.
2441 * m4/input.c (struct input_block): Add a flags field to facilitate
2443 (m4_push_macro): ...use it.
2444 (init_macro_token): Retrieve it.
2445 (m4_next_token): Initialise it.
2446 * m4/macro.c (expand_argument): Copy it.
2447 * m4/m4module.h: Adjust.
2448 * tests/builtins.at: Adjust the expected output of the trace
2449 tests to reflect the change in semantics.
2450 * tests/modules.at (modules: trace): Check that unloading a
2451 module which supplies a traced symbol definition doesn't lose te
2454 2001-10-07 Gary V. Vaughan <gary@gnu.org>
2456 * modules/gnu.c (m4_macro_table): Display the timetamp when
2457 expanding __m4_version__.
2459 * configure.ac (--with-modules): Forgot a comma in the
2460 AC_HELP_STRING parameter list.
2462 2001-10-05 Gary V. Vaughan <gary@gnu.org>
2464 * bootstrap: Remove aclocal.m4t when it is no longer required.
2466 2001-10-05 Akim Demaille <akim@epita.fr>
2468 * tests/Makefile.am: Adjust for gnuprog2.
2469 * tests/m4.in: There can be a leading path.
2470 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
2471 * tests/testsuite.at: Adjust to the most recent Autotest.
2472 (AT_CHECK_M4_FILTER): Fix and rename as...
2474 * tests/others.at: Use it.
2476 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
2477 variable in shell scripts, one uses `$'...
2479 2001-10-04 Gary V. Vaughan <gary@gnu.org>
2481 * configure.ac: `rm -f $m4_getopt_h' was lost.
2483 2001-10-04 Gary V. Vaughan <gary@gnu.org>
2485 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
2486 time. Define it for config.h in order to...
2487 * src/main.c (main): ...display the timestamp for --version.
2489 2001-10-04 Akim Demaille <akim@epita.fr>
2491 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
2492 previous builtins `regexp' and `patsubst'.
2493 (regexp, patsubst): Use them.
2494 (eregexp, epatsubst): New builtins.
2495 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
2496 (Epatsubst and Patsubst, Eregexp and Regexp): these.
2497 (Extensions): More info on REs.
2499 2001-10-04 Akim Demaille <akim@epita.fr>
2501 * modules/modtest.c (init_handler): Consistently output to stderr.
2502 (finish_handler): New.
2503 (test): The `if' is an `assert'.
2504 * tests/modules.at: Adjust.
2506 2001-10-04 Akim Demaille <akim@epita.fr>
2508 * m4/utility.c (m4_bad_argc): Detail the mismatches.
2510 2001-10-01 Akim Demaille <akim@epita.fr>
2512 * tests/generate.awk: Tag the tests with `documentation'.
2513 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
2514 Use the make the existing modtest tests more uniform, and complete
2515 the set of possibilities.
2517 2001-10-01 Akim Demaille <akim@epita.fr>
2519 * config/gmp.m4: Consult the user before using GMP: use
2521 * configure.ac: Adjust.
2522 * modules/gmp.c: No protection needed as the module is not built
2525 2001-10-01 Akim Demaille <akim@epita.fr>
2527 * tests/generate.awk: Remove debugging code.
2528 (fatal): Specify the current location.
2530 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
2531 * modules/gnu.c, modules/m4.c: Use M4ARG.
2533 2001-10-01 Akim Demaille <akim@epita.fr>
2535 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
2536 (m4_regexp_compile): New.
2537 (regexp, patsubst): Use it.
2539 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2541 Reinstate the memory handling improvements from the patch I just
2542 reverted. Relevant ChangeLog entries repeated here:
2544 * m4/module.c (m4_module_remove): New function that holds the core
2545 of the old m4_module_unload.
2546 (m4_module_unload): Use it.
2547 (m4_module_unload_all): When we know the modules will never be
2548 used again (i.e. on exit), free up as much module memory as
2549 possible. There are still some artifacts from resident modules
2550 living inside ltdl.c, but everything else is freed.
2551 * m4/debug.c (m4_debug_exit): Free memory allocated in
2553 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
2554 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
2555 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
2556 * m4/m4module.h: Updated prototypes.
2557 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
2558 * m4/hash.h: Updated prototypes.
2559 * src/main.c (main): Use all these new functions to clean up as
2560 much memory as possible before exit.
2562 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2564 Reverted my large patch for removing the old m4_symbol
2565 structure on 2001-09-20. We are still not happy about the way
2566 trace works in conjunction with defn and undefine, and leaving
2567 the reverted patch active prevents us from moving the traced
2568 bit from the definition back to the symbol.
2570 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2572 * configure.in: Moved to...
2573 * configure.ac: ...here. Added a libtool like timestamped
2574 banner, and tidied up the libltdl cruft.
2575 * config/mkstamp: Script to extract a timestamp from ChangeLog.
2576 * modules/Makefile.am (INCLTDL): Removed. This is required
2577 only when libltdl is configured in a subdirectory.
2578 * src/Makefile.am: Ditto.
2579 (LIBADD_DL): No need to add this again, libtool already knows
2580 that libm4.la depends on it.
2581 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
2584 * TODO: stackovf.c is basically broken.
2585 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
2587 2001-09-28 Akim Demaille <akim@epita.fr>
2589 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
2591 2001-09-27 Akim Demaille <akim@epita.fr>
2593 * tests/m4.in: Don't use short options.
2594 Simplify the stderr signature normalization.
2596 2001-09-27 Akim Demaille <akim@epita.fr>
2598 tests/m4 shall be position independent.
2602 * tests/testsuite.at: No args to AT_INIT.
2603 * configure.in, tests/Makefile.am: Adjust.
2605 2001-09-22 Akim Demaille <akim@epita.fr>
2607 Autotest has changed again.
2609 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
2610 (package.m4): Remove.
2611 * configure.in: Adjust to LIBADD_GMP.
2613 2001-09-21 Gary V. Vaughan <gary@gnu.org>
2615 * config/gmp.m4 (AC_ARG_WITH): Removed.
2616 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
2617 (AC_LIB_GMP): When performing a test compile against libgmp,
2618 include the header gmp.h if possible, and link against -lgmp. If
2619 they both work define USE_GMP.
2620 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
2621 (mpeval_LTX_init_func): Complain on load that there was no libgmp
2624 2001-09-20 Gary V. Vaughan <gary@gnu.org>
2626 * m4/evalparse.c: Moved to...
2627 * modules/evalparse.c: ...here. This code is shared between
2628 modules/mpeval.c and modules/m4.c, so there is no need to pollute
2629 the libm4 API with its details. Moderately rewritten to interface
2630 into its clients more simply.
2631 * m4/eval.c: Deleted. Migrated functionality to...
2632 * modules/m4.c: ...here.
2633 (builtin_eval): Implemented in terms of the new interface style.
2634 * modules/mpeval.c (builtin_mpeval): Ditto.
2635 * m4/m4module.h: Removed references to the former m4/eval.c.
2636 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
2637 (EXTRA_libm4_la_SOURCES): Deleted.
2638 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
2639 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
2641 2001-09-20 Akim Demaille <akim@epita.fr>
2643 * config/gmp.m4 (AM_WITH_GMP): Rename as...
2645 By default, use gmp.
2647 * configure.in: Adjust.
2648 Use Automake conditionals for USE_GMP.
2649 Always compute sizeof (long long int).
2650 This was a bug BTW, as `eval' (not `mpeval') depends on it:
2651 before, it was used _only_ if mpeval was not activated.
2652 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
2653 (mpeval_la_LIBADD): New macros.
2654 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
2656 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
2657 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
2660 2001-09-20 Akim Demaille <akim@epita.fr>
2662 * tests/Makefile.am (package.m4): New.
2663 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
2665 2001-09-20 Gary V. Vaughan <gary@gnu.org>
2667 More cleanup. After the last patch, m4_symbol holds nothing but
2668 the head of a chain of m4_token_data. So I have removed the old
2669 m4_symbol, so that m4_token_data chains are stored directly in the
2670 value cell of a hash table node. But there's more... m4_symbol
2671 was a more natural name for the symbol value cell, and now that it
2672 is gone I have renamed the former m4_token_data structure to
2673 m4_symbol. This change turned out to be a pig to get right, since
2674 the original code didn't need to modify the value cell itself,
2675 since changing the chain happened inside the m4_symbol that used
2676 to be returned -- I had to pass the address of the value cell
2677 across various function calls, incase the head value changed. I
2678 also tightened up the memory management to help me find a nasty
2679 memory corruption bug that took me all night to track down...
2681 * m4/m4private.h (struct m4_symbol): Removed.
2682 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
2684 * m4/hash.c (m4_hash_iterator_value): Return the address of the
2685 value cell. Updated all callers.
2686 * m4/symtab.c: Took advantage of the simplification in the data
2687 structures to rewrite a lot of this file more simply. There is
2688 still some room for optimisation here, but we should tackle that
2689 systematically closer to the release.
2691 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
2692 revealed. This version is ahead of CVS libtool until I get chance
2693 to flush my changes.
2694 * m4/module.c (m4_module_remove): New function that holds the core
2695 of the old m4_module_unload.
2696 (m4_module_unload): Use it.
2697 (m4_module_unload_all): When we know the modules will never be
2698 used again (i.e. on exit), free up as much module memory as
2699 possible. There are still some artifacts from resident modules
2700 living inside ltdl.c, but everything else is freed.
2701 * m4/debug.c (m4_debug_exit): Free memory allocated in
2703 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
2704 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
2705 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
2706 * m4/m4module.h: Updated prototypes.
2707 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
2708 * m4/hash.h: Updated prototypes.
2709 * src/main.c (main): Use all these new functions to clean up as
2710 much memory as possible before exit.
2712 2001-09-18 Gary V. Vaughan <gary@gnu.org>
2714 The `traced' flag needs to be attached to the definition of a
2715 symbol rather than the current symbol containing the definition.
2716 Implementing this showed up some long standing post 1.4 bugs in
2717 flag propogation which I also fixed.
2719 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
2720 (struct m4_token_data): And add it back in here.
2721 * m4/input.c (init_macro_token): Propogate the traced flag
2723 * m4/macro.c (expand_argument): Ditto.
2724 * tests/builtins.at (trace2, trace3): New tests based on Akim's
2727 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2729 * m4/m4private.h (struct m4_token_data): Simplified by removing
2730 the redundant `traced' flag, and one level of structure nesting.
2731 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
2732 * m4/input.c (init_macro_token): No need to initialise removed
2734 * m4/macro.c (expand_argument): No need to copy it either.
2735 * m4/utility.c (m4_token_data_func_traced): Or provide an access
2738 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
2739 dependant on multiple symbols with the same key, so preserving
2740 relative symbol order in each bucket during resizing is no longer
2741 required. The resize function is considerably faster as a result.
2743 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
2744 s/m4_symbol_insert/m4_symbol_define/g;
2745 s/m4_builtin_insert/m4_builtin_define/g;
2746 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
2748 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2750 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
2751 commits, the m4_lookup_symbol dispatch function is split into
2752 specialised functions that must be called directly.
2754 * m4/m4module.h (m4_symbol_lookup_t): Removed.
2755 * m4/symtab.c (m4_lookup_symbol): Removed.
2756 (m4_symbol_builtin, m4_symbol_macro): New functions.
2757 * m4/builtin.c (m4_builtin_define): Split into...
2758 (m4_builtin_pushdef, m4_builtin_insert): ...these.
2759 (m4_macro_define): Split into...
2760 (m4_macro_pushdef, m4_macro_insert): ...these.
2761 * src/main.c (main): Set command line macros from `-D' parameters
2762 using `m4_macro_define'.
2764 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2766 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
2767 this from m4_remove_table_reference_symbols().
2768 * m4/m4module.h, m4/module.c: Updated all references.
2770 2001-09-07 Akim Demaille <akim@epita.fr>
2772 * modules/stdlib.c, modules/times.c: Misc cleanups.
2774 2001-09-07 Akim Demaille <akim@epita.fr>
2776 * configure.in: We now need Autoconf 2.52e.
2777 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
2778 and `M4_SYMBOL_DELETE'.
2779 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
2780 * src/main.c (main): Adjust.
2782 2001-09-06 Gary V. Vaughan <gary@gnu.org>
2784 Fix the obstack.h problem once and for all! At configure time we
2785 can test for a system supplied obstack.h: depending on the
2786 result, we now generate system.h with an #include of the correct
2787 header. As a bonus, I've also added a --with-included-obstack,
2788 incase the user doesn't like the system obstack for some
2789 reason... and also we can test the shipped obstack on a system
2790 that has oe of its own. We also now need to be careful to add
2791 build directories to the include search path, since the generated
2792 system.h will be in the build tree.
2794 * configure.in (AC_CONFIG_FILES): Generate system.h from
2796 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
2797 include the system obstack header or the copy shipped with M4.
2798 Allow the user to override configure and force the build to use
2799 the shipped version.
2800 * m4/system-h.in: New file, template for...
2801 * m4/system.h: ...this. Now deleted.
2802 * m4/m4module.h: Include system.h before everything else.
2803 * src/freeze.c: Ditto.
2804 * m4/Makefile.am (dist-hook): Remove generated system.h.
2805 (INCLUDES): Check builddir for generated headers before checking
2807 * modules/Makefile.am (INCLUDES): Ditto.
2808 * src/Makefile.am (INCLUDES): Ditto.
2810 2001-09-05 Gary V. Vaughan <gary@gnu.org>
2812 * TODO: Remove the items that have been addressed already.
2814 2001-09-05 Akim Demaille <akim@epita.fr>
2816 * src/main.c (main): Standardize --version.
2818 2001-09-05 Akim Demaille <akim@epita.fr>
2820 * modules/format.c (format): Have a bigger `str'.
2822 2001-09-05 Akim Demaille <akim@epita.fr>
2824 Rationalize warnings, reporting the macro name as if it were a
2825 program name, and assertions.
2827 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
2829 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
2831 Use assert for internal errors.
2832 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
2834 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
2836 * tests/builtins.at (pushpop): Adjust.
2838 2001-09-05 Akim Demaille <akim@epita.fr>
2840 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
2843 2001-09-05 Akim Demaille <akim@epita.fr>
2845 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
2846 * m4/macro.c, m4/symtab.c: Adjust.
2848 2001-09-05 Akim Demaille <akim@epita.fr>
2850 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
2851 (m4_symbol_pop, m4_symbol_del): this.
2852 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
2853 (m4_symbol_popdef, m4_symbol_delete): New.
2854 (m4_lookup_symbol): Adjust.
2855 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
2857 2001-09-05 Akim Demaille <akim@epita.fr>
2859 * m4/m4module.h (m4_symbol_lookup): Rename as...
2860 (m4_symbol_lookup_t): this.
2862 2001-09-05 Akim Demaille <akim@epita.fr>
2864 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
2866 * m4/symtab.c (m4_lookup_symbol): Adjust.
2868 2001-09-03 Gary V. Vaughan <gary@gnu.org>
2870 Bootstrap will now work with Libtool 1.4.1 or higher:
2871 * bootstrap: Remove stale autom4te.cache files when
2873 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
2875 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
2876 libtool.m4 directly.
2877 Run libtoolize to refresh ltmain.sh.
2878 * config/ltmain.sh: Deleted.
2879 * acinclude.m4: Deleted.
2880 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
2882 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
2883 implementation for the cvs impaired libtool user.
2885 2001-09-03 Akim Demaille <akim@epita.fr>
2887 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
2889 Avoid using `default' in switch, as it hides useful compiler
2890 warnings when a case is forgotten.
2892 2001-09-03 Akim Demaille <akim@epita.fr>
2894 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
2895 is no such thing as `WITH_MODULES'.
2897 2001-09-03 Akim Demaille <akim@epita.fr>
2899 Improve the test suite's selfcontainedness.
2901 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
2902 (Include, Undivert): Tag the other input files.
2903 * tests/generate.awk: Catch `@comment file:'.
2904 `-I $src' is no longer needed.
2905 `next' is really like `return': the rest is skipped.
2906 Adjust to `input.m4'.
2907 (fatal): New function.
2908 * tests/foo, tests/incl.m4: Remove.
2910 2001-09-01 Gary V. Vaughan <gary@gnu.org>
2912 The shadowing mechanism and, infact, the whole symbol table
2913 implementation was creaking under the weight of the features piled
2914 on top of it. We now have a separate hash table module which will
2915 dynamically resize to keep symbol density withing good performace
2916 limits, and a new symtab module layered above it. Symbol lookups
2917 are now marginally more efficient (since the shadowed flag is no
2918 longer required) and symbol removal, such as on module unload, is
2919 considerably faster due to a reorganisation of the data structures
2922 * src/main.c (main): Don't mention `-H'.
2923 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
2926 * m4/hash.c: New generalised dynamic hash table data structure
2928 * m4/hash.h: Public interface.
2929 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
2930 (libm4_la_SOURCES): Add hash.c.
2931 * m4/symtab.c: More or less rewritten from scratch, within the
2932 bounds of the previous API.
2933 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
2934 call. Updated all callers.
2935 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
2936 declarations to reflect API changes.
2937 (M4INIT): Generate a declaration too, to avoid the warning with
2938 --enable-debug builds.
2941 * m4/utility.c (hash_table_size): Removed.
2942 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
2943 names, which are then looked up by builtin_dumpdef() as necessary.
2944 This implies a small speedup in builtin_symbols(), which discarded
2945 all of the symbol info under the old call.
2946 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
2947 shadowing is implicit in respect to the new data structures.
2948 symbol names are no longer duplicated here, they are stored in the
2949 key field of the hash table.
2950 Moved macro_args and blind_no_args...
2951 (m4_token_data): ...to here.
2952 m4/macro.c (expand_macro): Added a name argument since the symbol
2953 name is no longer copied into each struct m4_symbol. Modified all
2955 (collect_arguments): Ditto.
2956 * modules/m4.c (set_trace): Ditto.
2957 * modules/gnu.c (builtin_symbols): Updated.
2958 * src/freeze.c (produce_symbol_dump): Much improved in light of
2959 the improved symbol table layout.
2961 2001-09-01 Gary V. Vaughan <gary@gnu.org>
2963 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
2965 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
2966 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
2967 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
2968 SYMBOL_HANDLE): Ditto.
2969 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
2970 modules/gnu.c, modules/m4.c, src/freeze.c,
2971 src/main.c: Updated all references.
2973 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
2974 Automake 1.5 chokes on dynamic source file lists, Besides, it is
2975 already listed in m4_LDADD... how did that ever used to work?
2976 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
2978 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
2979 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
2981 * tests/m4: Don't call the m4 wrapper script with libtool, it
2982 works fine all by itself.
2984 2001-08-30 Gary V. Vaughan <gary@gnu.org>
2986 The experimental `changeword' feature never took off, and has
2987 no obvious advantages over `changesyntax' to compensate the
2988 enormous speed penalty it carries:
2989 * configure.in (ENABLE_CHANGEWORD): Removed.
2990 * m4/m4module.h (m4_set_word_regexp): Removed.
2991 * m4/m4private.h (m4_token_data): Removed original_text field.
2992 * m4/utility.c (m4_token_data_orig_text): Removed.
2993 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
2994 * m4/macro.c: Ditto.
2995 * src/main.c: Ditto.
2996 * modules/Makefile.am (changeword.la): Removed.
2997 * modules/changeword.c: File removed.
2998 * doc/m4.texinfo: References to changeword and --word-regexp
3000 * po/POTFILES.in: modules/changeword.c removed.
3001 * tests/atlocal.in (ENABLE_CHANGEWORD): Removed.
3002 * tests/builtins.at (changeword): Test removed.
3004 2001-08-30 Akim Demaille <akim@epita.fr>
3006 * bootstrap.sh: Create aclocal.m4 instead of modifying it.
3007 This also help having a single list of m4 files: in
3009 * config/Makefile.am (STANDARD_MACROS): Rename as...
3010 (ACLOCAL_MACROS): this.
3011 (list-standard-macros): Remove.
3014 2001-08-29 Gary V. Vaughan <gary@gnu.org>
3016 In an attempt to moderate my egomania...
3017 * tests/modules.at: Remove attributions.
3019 * tests/generate.awk: When making substitutions to "@&t@", either
3020 "&" or "\&" in the substitution string argument to gsub refer back
3021 to the matched text. "@\\&t@" seems to work though, Tests 43 and
3024 2001-08-29 Akim Demaille <akim@epita.fr>
3026 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)
3027 (include, indir, multiquotes, patsubst, pushdef/popdef, regexp)
3028 (sync-lines, trace, translit, undivert, wrap): Move to...
3029 * tests/builtins.at: this new file.
3030 * tests/others.at (Discard comments, import-environment): Move to...
3031 * tests/options.at: this new file.
3033 2001-08-29 Akim Demaille <akim@epita.fr>
3035 * tests/others.at (Freezing modules)
3036 (--module-directory: absolute path, modpath2, modpath3)
3037 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
3038 * tests/modules.at: here, new file.
3039 * tests/others.at, tests/generate.awk: Add a banner.
3040 * tests/testsuite.at: Adjust.
3041 (AT_CHECK_M4_FILTER): New, but unused.
3043 2001-08-29 Akim Demaille <akim@epita.fr>
3045 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
3047 * tests/others.at (wrap): Inline wrap.m4.
3048 (shadow): Inline shadow.m4.
3049 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
3050 * tests/m4: Simplify.
3052 2001-08-29 Akim Demaille <akim@epita.fr>
3054 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
3057 2001-08-29 Akim Demaille <akim@epita.fr>
3059 * tests/generate.awk (normalize): s/@__@/@&t@/.
3061 2001-08-28 Akim Demaille <akim@epita.fr>
3063 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.
3065 2001-08-28 Gary V. Vaughan <gary@gnu.org>
3067 * bootstrap (generate.awk): Generate test cases with new script.
3069 2001-08-27 Akim Demaille <akim@epita.fr>
3071 * tests/Makefile.am (installcheck-local): Don't use
3072 `dc_install_base' which is not visible here, but `exec_prefix'
3073 which is clearly the RT anyway.
3074 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
3075 related to testing a now installed m4.
3076 * tests/m4: Do it here.
3078 2001-08-27 Akim Demaille <akim@epita.fr>
3080 * tests/others.at (indir): Formatting change.
3082 2001-08-27 Akim Demaille <akim@epita.fr>
3084 * tests/Makefile.am (installcheck-local): New.
3085 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
3087 Prefer options over envvars.
3088 * src/main.c (main): First bug caught by the test suite (yeah!):
3089 --batch lacked a `break' which resulted in an accidental
3090 invocation of --discard-comments.
3092 2001-08-27 Akim Demaille <akim@epita.fr>
3094 * tests/others.at (capitalize, changeword, comments, ddivert)
3095 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
3096 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
3097 (sysv-args, trace, translit, undivert): Don't rely on files in
3098 examples/: AT_DATA them.
3100 2001-08-27 Akim Demaille <akim@epita.fr>
3102 Let the test suite use a wrapper around the not installed m4 to
3103 pretend it is (installed).
3105 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
3106 such a way that m4 does not process them.
3107 * configure.in: The package name seems to be `m4', not `M4'.
3109 * tests/atlocal.in (at_package, M4): Remove.
3110 * tests/testsuite.at, tests/others.at: Use m4, not $M4.
3112 2001-08-27 Akim Demaille <akim@epita.fr>
3114 * tests/Makefile.am (CLEANFILES): Remove.
3115 (DISTCLEANFILES, clean-local): New.
3116 * examples/mktests.sh: Remove.
3118 2001-08-27 Akim Demaille <akim@epita.fr>
3120 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
3121 Don't use aclocal: it's written by hand.
3122 * aclocal.m4: m4_include all the files instead of being built by
3124 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
3125 until it reads the traces by itself.
3126 * configure.in: Require Autoconf 2.42c as we are now using
3127 AC_CONFIG_TESTDIR instead of AT_CONFIG.
3128 Catch unexpanded `jm_' macros.
3129 * config/atconfig.m4: Remove.
3130 * config/error.m4: new.
3131 * config/Makefile.am: Ship the files included by aclocal.m4.
3132 * tests/Makefile.am (TESTSUITE_SOURCES): Rename as...
3133 (TESTSUITE_AT): this, to please Automake.
3134 (TESTSUITE): This target uses autotest/autotest.m4, not
3135 autotest/general.m4.
3136 * tests/testsuite.at: Prereq Autotest 2.52c.
3137 * examples/Makefile.am (pkgdata_DATA): Rename as...
3138 (dist_pkgdata_DATA): this.
3139 * doc/Makefile.am (man_MANS): Rename as...
3140 (dist_man_mans): this.
3142 2001-08-20 Gary V. Vaughan <gary@gnu.org>
3144 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
3145 Robert Collins, building on Cygwin no longer requires Windows
3146 import and export symbol decorations.
3147 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.
3148 * m4/error.h (M4_SCOPE) [cygwin*]: Ditto.
3149 * m4/debug.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
3150 * m4/error.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
3151 * m4/input.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.

3155 * m4/xmalloc.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
3156 * configure.in (LIBM4_DLL_IMPORT) [cygwin*]: Don't set this
3158 * src/Makefile.am (AM_CPPFLAGS) [cygwin*]: Don't use it either!
3159 * modules/Makefile.am (AM_CPPFLAGS) [cygwin*]: Ditto.
3161 2001-08-20 Gary V. Vaughan <gary@gnu.org>
3163 Ansify the source. Previously we had a mix, where my code was
3164 in a K&R compatible style, and the preexisting code was in ANSI
3165 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
3166 and now the code base is much cleaner.
3168 * m4/system.h: Remove M4_PARAMS macro and all users. Remove

3210 * modules/m4.c (undivert): Disable the possibility of undiverting
3211 several files at once: it is not documented, it is inconsistent
3212 with the other macros, it can be straightforwardly mocked by

3380 it's defined, M4sugar moved it as m4_changeword.

3438 (M4FINISH_HANDLER): And similarly for finish functions.

3455 instead of the old module argument.
3456 (m4_builtin_table_install): Ditto.
3457 * modules/load.c (m4_resident_module): Removed. This is no

3478 module association does not belong with the symbol...
3479 * m4/input.c (struct m4_builtin): ...it belongs with the builtin

3499 * tests/gethem: Use them.
3501 2001-08-14 Gary V. Vaughan <gary@gnu.org>

3518 shell variable m4_cv_func_obstack_h.

3520 script and m4 binary by using $srcdir.

3523 optargs to the existing libltdl search path.
3524 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.

3531 * src/main.c (main): Add `-b' (for `batch') mode switch to force
3532 interactive mode off.

3598 with symbol insertion and deletion with resident modules.

3600 use resident modules feature.
3602 2000-11-30 Gary V. Vaughan <gary@gnu.org>

3661 modules/unfrozen.m4, modules/unload.test: Removed.
3663 Move the implementation of GMP support for the mpeval() builtin
3664 into a loadable module that depends on libgmp. mpeval() and
3665 eval() share a common parser, now in m4/evalparser.c; the code
3666 in m4/numb.c and m4/numb.h is now physically split between
3667 m4/eval.c (the eval() backend) and modules/mpeval.c (the
3668 mpeval() backend), rather than being differentiated by cpp
3669 macros and multiple inclusion. The mpeval module is always
3670 built but will generate an diagnostic if it is used from an
3671 installation that didn't link in the gmp library.
3672 * modules/Makefile.am: build and install the new mpeval module.
3673 * modules/mpeval.c: Now contains the former parts of m4/numb.c
3674 and m4/numb.h that are required for gmp support in mpeval().
3675 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
3676 * m4/evalmp.c: Removed.
3677 * m4/m4module.h: Removed conditional prototype for
3679 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
3680 and m4/numb.h that do not rely on gmp.
3681 * m4/evalparse.c: New file, contains the shared parts of the
3682 eval() and evalmp() parser implementations, and is no longer
3683 unencumbered by cpp magic to uncover the right parts.
3684 * m4/numb.h: Removed. It's former contents are split between
3685 m4/eval.c and modules/mpeval.c.
3688 * tests/other-tests/changeword.test: New test. Rudimentary
3689 testing of changeword builtin runs only if --wnable-changeword
3690 was used at configure time.
3691 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
3692 alternation correctly. Split into two expressions to compensate.
3693 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
3694 * modules/Makefile.am: Build changeword module.
3695 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
3696 only when --enable-changeword was passed to configure.
3697 (builtin_changeword): If --enable-changeword was not used, then
3698 report that changeword() builtin has no support in m4 binary.
3700 2000-11-28 Gary V. Vaughan <gary@gnu.org>
3702 * src/main.c (main): Fixed a particularly nasty bug is
3703 user_search_path setting -- the -M flag processing must be
3704 extremely careful with search path ordering, or else the default
3705 installed module directory (possibly containing modules from a
3706 previous release) is placed earlier in the search path than any -M
3707 arguments (which are relied upon to load uninstalled modules with
3708 most of the tests in the regresion suite).
3710 * modules/load.c (builtin_load): Nasty hack to prevent adding
3711 symbols to symtab again if a module is loaded more than once.
3712 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
3714 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
3715 possible NULL pointer dereference.
3717 * m4/module.c (m4_module_find_by_modname): Renamed from
3718 m4_module_modname_find. Fixed all references.
3719 (m4_module_find_by_builtin): New function.
3721 * modules/modfreeze.test: load the `load' module with each
3723 * src/freeze.c (produce_frozen_state): Simplified in light of
3724 module field in m4_symbol. Allow a third argument for text macros
3725 to name the originating module.
3726 (reload_frozen_state): ditto.
3727 * m4/m4module.h: Fixup prototypes.
3728 * m4/builtin.h (m4_builtin_define): Add a module argument so
3729 that symbols can be registered against the defining module.
3730 (m4_macro_define): ditto.
3731 * m4/m4private.h (m4_symbol): Make the module field const to save
3732 on casting in the rest of the code.
3733 (SYMBOL_MODULE): New macro.
3735 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
3736 symbol reference maintenance bugs when removing a symbol from the
3739 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
3741 2000-11-27 Gary V. Vaughan <gary@gnu.org>
3743 * configure.in (m4_cv_func_obstack): A better check for whether
3744 libc has an obstack implementation.
3745 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
3747 * configure.in (--with-modules): Changed semantics. This
3748 option is now used to list modules to be preopened.
3749 * src/m4.h: #include "ltdl.h" unconditionally.
3750 * src/main.c: Removed all dependencies on WITH_MODULES.
3751 * src/freeze.c: ditto.
3752 * modules/Makefile.am: ditto.
3753 * m4/m4.c (builtin_m4exit): ditto.
3754 * modules/modpath1.test: ditto.
3755 * modules/modpath2.test: ditto.
3756 * modules/modpath3.test: ditto.
3757 * modules/modpath4.test: ditto.
3758 * modules/modtest.test: ditto.
3759 * modules/shadow.test: ditto.
3760 * modules/unload.test: ditto.
3762 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
3763 comes up on demand in LTLIBOBJS now.
3764 * configure.in (getopt_long): Creating and relying on a link for
3765 getopt.h on hosts with no getopt_long() of thier own works
3766 correctly now. This is necessary so that callers of getopt_long()
3767 can simply `#include <getopt.h>': the naive way of doing this
3768 would end up using our own getopt.h and the installed
3769 getopt_long(), which is asking for trouble!
3770 (obstack_init): A similar argument applies to obstack.h and
3773 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
3774 On Solaris-2.5 (at least) the native dlopen implementation
3775 gets confused about m4.o when looking for module "m4". This
3776 version always looks for .la an .$lib_ext suffixed names first
3777 to work around the problem. Sigh.
3779 * po/POTFILES.in: Take account of these file movements.
3780 * src/Makefile.am (m4_SOURCES): removed eval.c.
3781 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
3782 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
3783 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
3784 * modules/m4.c (builtin_eval): Use m4_evaluate().
3785 * m4/eval.c: Moved here from src/eval.c to facilitate
3786 implementation of eval() builtin as part of the `m4' loadable
3788 (m4_evaluate): renamed from evaluate for namespace cleanliness.
3789 * m4/numb.c: Moved here from src/numb.c, since it is #included
3790 into eval.c at compile time.
3791 * m4/m4module.h (m4_evaluate): Added prototype.
3792 * src/m4.h (evaluate): Removed prototype.
3794 2000-11-25 Gary V. Vaughan <gary@gnu.org>
3796 * modules/perl.c (builtin_perleval): Use PL_na for
3797 compatibility with perl-5.6.
3799 * src/main.c (main): It is now safe to
3800 ``m4_module_install("m4")'', without tripping over the m4
3802 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
3803 versions having fixed the insidious module search order bug.
3805 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
3806 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
3808 * configure.in: Figure out whether to use the installed
3809 getopt.h or the supplied one.
3810 * src/Makefile.am: ditto.
3812 * po/POTFILES.in: List files in their new positions.
3814 * config/ltmain.sh: This needs to be checked in to match the
3815 libtool macros copied to acinclude.m4 (until a released
3816 libtool copes with m4's needs).
3817 * bootstrap: Run gettextize.
3819 2000-11-24 Gary V. Vaughan <gary@gnu.org>
3821 * AUTHORS: Added my details.
3824 * bootstrap: temporary update until released libtool catches up.

3860 * modules/gnu.c: New file implementing a new loadable module wuth
3861 definitions for all the gnu extension builtins.
3862 * modules/format.c: Moved here from src/format.c. Now included
3865 * src/main.c (main): Load the traditional module if m4 was
3866 started in `no_gnu_extensions' mode.
3867 * modules/traditional.c: New file implementing the ``unix'' macro,
3868 required when m4 is executed in traditional mode, as a loadable

3886 * m4/symtab.c: ditto.
3887 * m4/debug.c: ditto.

3889 * m4/output.c: ditto.
3891 * m4/ltdl.h, m4/ltdl.c: ditto.
3892 * m4/utility.c: Odd functions moved here from files in the src
3893 directory to facilitate builtin migration.
3895 2000-08-12 Gary V. Vaughan <gary@gnu.org>
3897 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
3898 error message, to make translators' jobs a little easier.
3899 (builtin_builtin): ditto.
3900 (builtin_traceon): ditto.
3901 (builtin_traceoff): ditto.
3902 Reported by Akim Demaille <akim@epita.fr>

3905 pkgincludedir instead.

3928 makeinfo calculates them for us, and to make any future
3929 reorganisation easier.
3930 (Frozen files): Document format version 2.
3931 `V' now takes argument `2'.
3932 `F' can take a single argument if symbol and builtin names
3933 are the same, or 3 arguments if the builtin is from a module.

4071 * src/m4.c (main): Assume interactive mode if STDIN is connected

4074 initialised from here when loading a frozen file.
4076 * src/builtin.c: Much improved macro definition style.
4077 * src/m4private.h: Internal structures for m4_builtin and

4091 table entries which refer to a given builtin table.

4116 before calling lt_dlinit!, fix warnings
4118 2000-01-18 Gary V. Vaughan <gary@gnu.org>

4131 * modules/modtest.test: ditto.
4132 * modules/modpath4.test: ditto.

4146 increment serial number.
4148 * Makefile.am (SUBDIRS): Moved @MODULES_DIR@ to compile before
4149 src dir and immediately after libm4 is built for confidence that
4150 it doesn't rely on the src directory.

4152 makeinfo stop the build on cygwin (because they don't work).
4154 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
4156 * m4/m4private.h: ...is not a public header, so moved to src.

4181 and then in $(top_srcdir)/lib (for eg. "m4private.h").
4182 * src/Makefile.am (m4_LDADD): replace libi/libm4.la with

4202 2000-01-17 Gary V. Vaughan <gary@gnu.org>
4204 * src/ltdl.c: Use access() to abort doomed module load attempts
4205 if module file does not exist.
4207 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
4208 getopt1.o will already be used if appropriate, so I moved getopt.c
4209 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
4211 * modules/modpath1.test: Use correct filename in header line.
4212 * modules/modpath2.test: ditto.
4213 * modules/modpath3.test: ditto.
4214 * modules/modpath4.test: ditto.
4216 Without these changes lt_dlopen("test") attempts to
4217 LoadLibrary("/bin/test") on Windows, which although harmless
4218 generates a spurious error message which spoils most of the tests:
4219 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
4220 (TESTS): s/test.test /modtest.test /
4221 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /

4229 2000-01-16 Gary V. Vaughan <gary@gnu.org>
4231 * src/ltdl.c (find_file): Updated to new version with fixed memory
4232 allocation bug in `next'.
4233 * src/ltdl.h: updated to match.
4235 * modules/Makefile.am: Cleaned up and reordered.
4237 2000-01-16 René Seindal <rene@seindal.dk>
4239 * modules/Makefile.am (TESTS): New tests for the module system.
4241 * modules/*.test: New files.
4243 * src/m4.c (main): Added call to module_init().
4244 Treats -M and -m as the arguments -D -U and -t, ie deferred.
4246 * src/m4.h: Added declaration of module_init().
4248 * src/module.c (module_init): No longer static
4250 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
4251 Added to shut up automake about non standard libtool library
4254 * src/module.c: Disabled DEBUG by default.
4256 * modules/README: Changed example from unload.m4 to shadow.m4
4258 * modules/shadow.m4: Renamed from unload.m4
4260 * modules/Makefile.am (EXTRA_DIST): Removed unload.m4.
4262 * src/m4.c (main): Functionality for -m and -M were reversed.
4265 2000-01-12 Gary V. Vaughan <gary@gnu.org>
4267 * doc/help2man.pl: updated to version 1.020.
4269 * lib/COPYING.LIB: updated to version 2.1.
4271 * lib/m4module.h: restructure the M4_SCOPE code to work when
4272 creating a dll which links with libm4.la and both DLL_EXPORT
4273 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
4276 2000-01-11 Gary V. Vaughan <gary@gnu.org>
4278 Merged the following changes from my tree:
4280 1999-06-15 Gary V. Vaughan <gary@gnu.org>
4282 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
4283 ported to compile shared libs.
4285 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
4286 use `__declspec(dllimport)' when linking libm4.la on win32.
4287 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
4289 * configure.in (M4OBJS): Discover whether we need the shipped
4290 implementation of getopt_long.
4291 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
4292 main binary here, as opposed to the module library in lib/libm4.la.
4294 1999-06-14 Gary V. Vaughan <gary@gnu.org>
4296 * modules/README: Updated to describe the improved libltdl based
4298 * README (cygwin): Added some compilation notes for building m4
4299 correctly under cygwin.
4300 * TODO: Cleaned out the entries for the module system since they
4301 are now implemented.
4303 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
4304 all instances of __P with M4_PARAMS.
4306 * lib/getdate.h: removed unreferenced file.
4308 * lib/m4private.h: New file to define the private interface to the
4309 token_data struct, which must be shared between m4module.c, and
4310 builtin.c but not exported to modules built from the installed
4311 m4module.h since it's size changes depending on compile time
4314 * src/m4.h: Lots of stuff moved to lib/m4module.h.
4316 * lib/m4module.h: New file to define the interface available when
4317 compiling m4 modules.
4318 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
4319 necessary for module compilation into this new file.
4321 * lib/Makefile.am (include_HEADERS): install headers (renamed to
4322 avoid nameclash with other system headers) necessary for compiling
4324 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
4325 so that modules can include the (renamed) installed headers and
4326 be guaranteed a matching implementation.
4327 * lib/m4error.h: renamed from error.h.
4328 * lib/m4obstack.h: renamed from obstack.h.
4329 * lib/m4regex.h: renamed from regex.h.
4330 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
4331 implementation, simply include the shipped version
4332 unconditionally, otherwise it is hard for a module to know
4333 whether the m4obstack.h header it is using matches the
4334 implementation it ends up linking against.
4335 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
4338 1999-05-18 Gary V. Vaughan <gary@gnu.org>
4340 * examples/misc.test: Don't run this test on machines which don't
4341 have a root user in /etc/passwd (e.g. cygwin).
4343 * tests/get-them (/^@example$/): Error messages might have a
4344 ``.exe'' suffix to the program name, or else use the libtool
4345 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
4346 of these cases are now catered for when comparing error messages
4348 * tests/other-tests/*.test: ditto.
4349 * examples/*.test: ditto.
4351 * tests/defs (M4): use libtool execute mode.
4352 * examples/defs (M4): ditto.
4354 * tests/get-them (END): explicitly close any open file.
4355 (printthem): In a regular expression, '{' is the start of a repeat
4356 count! Use `[{]' for a literal open brace.
4357 (/^@node /): Don't use substr on a string shorter than the trim
4360 1999-05-17 Gary V. Vaughan <gary@gnu.org>
4362 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
4364 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
4366 2000-01-10 Andreas Schwab <schwab@suse.de>
4368 * tests/other-tests/gmp.test: Find config.sh in build directory.
4370 * configure.in: Find tests/mkconfig.sh in $srcdir.
4372 * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in
4373 <signal.h> (for SUS2 compliant systems).
4375 * src/stackovf.c: Check for HAVE_SIGINFO_T in addition to
4378 2000-01-10 René Seindal <rene@seindal.dk>
4382 * TODO, NEWS: Cleaned up and updated.
4384 * src/m4.c (main): New variable exit_status for exit status in
4385 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
4386 file cannot be read instead of EXIT_SUCCESS.
4388 * src/builtin.c (m4_indir): Changed error message to help
4389 translators (from Akim Demaille <demaille@inf.enst.fr>).
4391 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
4394 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
4397 * src/input.c (match_input): Reordering of code, to avoid multiple
4398 calls to push_string_init() from obstack_grow(), which can happen
4399 with some compilers (found and fixed by James Bonfield
4400 <jkb@mrc-lmb.cam.ac.uk>).
4402 * src/stackovf.c: Added prototypes for ultrix.
4403 (setup_stackovf_trap): Added __P to cast.
4404 (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>)
4406 2000-01-09 René Seindal <rene@seindal.dk>
4408 * doc/m4.texinfo (Changequote): Added comment about changing
4409 quotes when the old quote is a part of the new.
4411 * src/builtin.c (expand_ranges): Added break after trailing dash.
4412 This caused misbehavious on some systems (found and fixed by Akim
4413 Demaille <demaille@inf.enst.fr>).
4415 * AUTHORS: Thomas Tanner included
4417 * acconfig.h: Added entry for ss_sp (see below).
4419 * configure.in (use_stackovf): Added check for stack_t with member
4420 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert
4421 <eggert@twinsun.com>).
4423 * doc/m4.texinfo (Frozen files): Added a simpler example for
4424 generating frozen files from several input files.
4426 1999-11-14 Paul Eggert <eggert@twinsun.com>
4428 * po/POTFILES.in: Add lib/getopt.c, lib/obstack.c,
4429 lib/regex.c, lib/xmalloc.c.
4431 1999-11-10 René Seindal <rene@seindal.dk>
4433 * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal.
4435 * src/module.c: reindented.
4436 (module_load): return if this is a repeated load of same module.
4437 (module_init): slight change of logic to avoid repeated
4438 initialisation debug messages.
4440 * Makefile.am (DIST_SUBDIRS): Added to ensure modules/ is included
4441 in the distribution.
4443 * modules/Makefile.am (test_la_LDFLAGS): set to -module to silence
4444 automake warnings about missing lib prefix.
4445 (time_la_LDFLAGS): ditto
4446 (stdlib_la_LDFLAGS): ditto
4448 1999-11-10 Paul Eggert <eggert@twinsun.com>
4450 * src/m4.h: Include error.h, since our macros use error.
4451 * src/m4.c: Don't need to include error.h.
4453 1999-11-09 Paul Eggert <eggert@twinsun.com>
4455 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
4456 and zero, as Solaris 7 cc does.
4457 (bcopy): Remove macro; no longer needed with new obstack.h.
4459 * src/output.c (freeze_diversions): Don't assume that a
4460 diversion size can fit in `int'. Check for diversion file
4461 size too large to be printed with `unsigned long'.
4463 * src/Makefile.am (CFLAGS): Omit -Wall.
4465 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.
4467 * src/debug.c (trace_format):

4481 * src/module.c: entirely new implementation using libltdl.
4482 * po/POTFILES.in: added src/module.c.
4483 * modules/Makefile.am (LTLIBRARIES): Removed lib prefix as these
4484 are modules, not linktime libraries.
4485 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
4486 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
4487 avoidance on exported symbols.
4488 * modules/test.c (m4_macro_table, m4_init_module,
4489 m4_finish_module): ditto.
4490 * modules/time.c (m4_macro_table): ditto.
4492 * modules/time2.m4: new file which requires command line loading
4494 * src/m4.c (--load-module): dynamically load named runtime module
4495 into running executable before reading the source.
4496 (--module-directory): prepend a directory to the module search
4498 (module_init()): Do this the first time we load a module instead;
4499 if the module subsystem is broken normal m4 scripts can still run.
4500 * src/m4.h (install_builtin_table): is now exported.
4502 1999-03-26 Gary V. Vaughan <gary@gnu.org>
4504 * src/module.c: removed. No longer required.

4514 * modules/Makefile.am (MAINTAINERCLEANFILES): ditto.
4515 * src/Makefile.am (MAINTAINERCLEANFILES): ditto.
4516 * tests/Makefile.am (MAINTAINERCLEANFILES): ditto.
4518 * acinclude.m4: removed. `aclocal -I acm4' handles this much
4520 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
4521 * acm4/gettext.m4: removed. It causes a multiple definition vs.
4522 the installed gettext.m4 file when running aclocal.
4524 1999-03-25 Gary V. Vaughan <gary@gnu.org>
4526 * configure.in (AM_INIT_AUTOMAKE): bumped version number to
4527 distinguish this from the last prerelease.
4528 (AC_LIBLTDL_CONVENIENCE): build libltdl as a convenience library
4529 in its own subdirectory.
4531 * modules/Makefile.am (*_SOURCES): renamed to use libtool's "no
4532 lib prefix on a module" feature.
4533 (LDFLAGS): Added `-module -avoid-version' flags to build
4534 versionless module libraries.
4535 * src/builtin.c (m4_load_module): use libltdl.
4536 (module_unload_all): use libltdl.
4537 * src/m4.c (module_init): initialise module loading on demand for
4538 better diagnostics, and so that m4 will still work even if
4539 the module code is broken.
4540 * src/m4.h (module_init): removed. No longer relevant.
4541 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on
4542 exported symbols for compatibility with dlpreopening.
4543 * modules/test.c (m4_macro_table, m4_init_module,
4544 m4_finish_module): ditto.
4545 * modules/time.c (m4_macro_table): ditto.
4547 * bootstrap: New file. Runs all the autoutils in the right order
4548 after a fresh checkout, or a make maintainer-clean.
4550 1999-02-18 Akim Demaille <demaille@inf.enst.fr>
4552 * src/builtin.c (dump_symbols): New function, factoring common
4553 content of m4_dumpdef and m4_symbols.
4554 (m4_dumpdef): Use it.
4555 (m4_symbols): New function, implementing `symbols'. Use it.
4556 * doc/m4.texinfo: Fixed missing commas after @xref, so that the
4557 file compile with modern makeinfo.

4559 (direntry): Modernize.
4561 1998-12-11 René Seindal <rene@seindal.dk>
4563 * src/builtin.c (predefined_tab): New predefined macros
4564 __m4_changeword__, __m4_gmp__ and __m4_modules__ for testing for
4565 configure time options.
4567 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
4569 * src/module.c (module_try_load): Don't try to be clever and
4570 overwrite argument string. Instead allocate all constructed
4571 strings locally, since they can have arbitrary lengths. Make
4572 arguments pointers to const.
4573 (module_search): Simplify due to above change.
4575 1998-11-29 René Seindal <rene@seindal.dk>
4579 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): New tests.
4581 * tests/other-tests/import-environment.{m4,test}: New test.
4583 * tests/other-tests/discard-comments.{m4,test}: New test.
4585 * doc/m4.texinfo (Invoking m4): Updated for --discard-comments.
4587 * src/m4.c (main): New option -c --discard-comments.
4588 New global variable discard_comments.
4590 * src/m4.h (token_type): New TOKEN_NONE for tokens to be
4591 discarded, ie never returned from next_token().
4592 Added declaration of discard_comments.
4594 * src/input.c (next_token): Now loops until token type is not
4595 TOKEN_NONE. Comments are now given this type when comments should
4598 * doc/m4.texinfo (Invoking m4): Updated for --import-environment
4601 1998-11-28 René Seindal <rene@seindal.dk>
4603 * src/m4.c (main): New option --import-environment (no single
4606 * When configured with --with-gmp both the normal (fast) eval()
4607 and the gmp aware mpeval() are defined. To restore previous
4608 bahaviour use "define(`eval', defn(`mpeval'))".
4610 * tests/other-tests/gmp.m4: Changed to use mpeval().
4612 * src/evalmp.c: New file for compiling eval.c as gmp aware.
4613 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
4615 * src/eval.c: Now includes "numb.c" directly. Everything in this
4616 file must by static, except evaluate(), which is changed to
4617 mp_evaluate() if USE_GMP in force.
4619 * src/numb.c: Changed to be included by eval.c instead of being
4620 compiled separately. Everything is declared static.
4622 * src/numb.h: Removed declarations of functions, as numb.c is now
4625 * src/builtin.c: Declaration of m4_mpeval() added.
4626 Inserted `mpeval' in builtin table.
4627 (do_eval): New function with common code for m4_eval and m4_mpeval.
4628 (m4_mpeval): New function for gmp version of eval.
4630 * src/m4.h: Declaration of mp_evaluate().
4632 * src/Makefile.am (m4_SOUCES): Includes mpeval.c.
4633 (EXTRA_m4_SOURCES): Now has numb.c and numb.h
4635 * src/m4.c (main): m4 --version also shows which options were used
4636 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
4638 1998-11-27 René Seindal <rene@seindal.dk>
4640 * Error messages now always print program name before input file
4641 name as specified by GNU coding standards. Reported by Akim
4642 Demaille <demaille@inf.enst.fr>.
4644 * doc/m4.texinfo (Include): Change due to changed error message
4648 * tests/get-them: Minor change to sed script due to changed error
4651 * src/m4.c (print_program_name): New func used to print program
4652 name, input file and line number in error (). Used as an
4653 error_print_progname handler.
4654 (reference_error): Removed.
4655 (main): Assigns error_print_progname.
4657 * src/m4.h (M4ERROR): Removed reference_error ().
4659 1998-11-25 René Seindal <rene@seindal.dk>
4661 * Updated to libtool 1.2b.
4663 * src/builtin.c (install_builtin_table): Added braces to avoid
4664 warning of ambiguous 'else'.
4666 * src/module.c: Inserted search path code from path.c modified to
4668 (module_init): Configured default path used only if M4MODPATH is
4670 (module_try_load): Now reads libMODULE.la as generated by libtool
4671 for actual module name.
4672 (module_load): Gives better error messages on failure.
4674 * src/m4.h: Added declarations of structures and functions for
4675 generic search path handling.
4677 * src/path.c: Removed all module specific code and introduced new
4678 functions of more generic search path handling.
4680 1998-11-24 René Seindal <rene@seindal.dk>
4682 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
4683 included gettext, as <libintl.h> might not be found
4684 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
4686 1998-11-22 René Seindal <rene@seindal.dk>
4688 * src/output.c (insert_diversion): Fixed bug that might cause m4
4689 to read from standard output! Triggered by input
4690 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
4691 so now 'undivert(0)' does nothing.
4693 1998-11-18 René Seindal <rene@seindal.dk>
4697 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
4698 could be changed when compiling a illegal regexp, causing later
4699 use of the regexp to dump core.
4701 * src/module.c (module_load): Changed error message to conform to

4759 * src/Makefile.am: Now generated pathconf.h which defined the
4760 default MODULE_PATH.

4763 where modules are installed.
4765 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
4766 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
4767 build and install automatically, and it is prepared for other
4768 interfacec than dlopen().
4770 * src/builtin.c (predefined_tab): Added __m4_version__ for the
4771 current version of GNU m4. It is a GNU extension.

4851 1998-10-07 René Seindal <rene@seindal.dk>
4855 * tests/Makefile.am (GENERATED_TESTS): Changed .m4 extension to
4856 .test, as the files are no longer just m4 input.
4858 * tests/get-them (FILE): Changed .m4 extension to .test.

4897 skip_space, bad_argc), and the macros ARG() and DECLARE().
4899 * src/builtin.c (install_builtin_table): New function. Each
4900 module brings in a builtin_table, which is pushed on a stack.
4901 (struct builtin_table): New struct for list of builtin_tables.
4902 (m4_loadmodule): New function to implement builtin "loadmodule".
4903 (shipout_int): No longer static, to be used by modules.

4924 * configure.in: Added modules/Makefile to AC_OUTPUT.
4926 * configure.in: Added code to implement --with-modules. Tests for
4929 * acconfig.h: Added WITH_MODULES
4931 1998-10-02 René Seindal <rene@seindal.dk>
4933 * examples/Makefile.am (pkgdata_DATA): Removed special target for
4934 check and variables TESTS. These tests are now run from the
4937 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
4938 directory. The files stay there but the tests are run from the
4941 * tests/Makefile.am (EXTRA_DIST): Added run-test.
4943 * tests/run-test: New file. Run a test manually
4945 * tests/Makefile.am, tests/get_them: Moved automatically generated
4946 tests (from the manual) to sub directory tests/gentest/. The
4947 tests/ directory had gotten a bit messy.
4949 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4951 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\
4952 wrap}.test: Added a few testcases.
4954 1998-08-21 Erick Branderhorst <Erick.Branderhorst@asml.nl>

4960 * configure.in (jm_WITH_REGEX, jm_PREREQ_ERROR):
4961 acm4/{error,regex}.m4 (from fileutils-3.16u.tar.gz).

4967 `C'. Reported by Ulrich Drepper.
4969 * Makefile.am (SUBDIRS): Removed checks directory
4970 * configure.in (AC_OUTPUT): Removed checks/Makefile
4972 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
4973 the space when m4.texinfo is edited and whitespace.el is active.
4974 (Defn,example): idem.
4976 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4978 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
4979 ../COPYING. ../Makefile is a file which is certainly present when
4980 test is executed in testSubDir. One can't be sure that the COPYING
4981 file is in .. or ../.. in all situations, the ../Makefile is
4984 * doc/m4.texinfo (Include): adjusted expected test output
4985 according to new tests, i.e. the input will always come from the
4986 file `in' created by the test.
4988 * tests/Makefile.am: Added three lines at the top to get
4989 esyscmd.1.test working.
4991 * tests/get-them: modified to generate clearer tests who will need
4992 less maintenance when new test examples are created in
4993 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
4994 need the generic file `defs') shell scripts creating `in', `ok',
4995 `out' and when apropriate `okerr' and `err' in the directory
4996 `testSubDir' when executed. The compare of `ok' and `out'
4997 (and of `okerr' and `err') will be the exit status of the test.
4998 `out' must match `ok' (and `okerr' must match `err') for the test
5001 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
5002 the tests generated by tests/get-them getting it input normally
5003 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
5004 (dot) before the numeric part) is reserved for all other (hand
5005 written) tests. The `+' means one or more times.
5007 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
5009 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
5010 supported short man page to refer to info documentation

5037 "changesyntax" to modify the syntax table.
5039 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax
5040 table. All categories are assigned a syntax code and tokens are
5041 read according to this table.
5043 1998-08-09 René Seindal <rene@seindal.dk>
5045 * src/numb.{c,h}: New files, implements multiple precision eval
5046 using GNU gmp. Originally submitted by John Gerard Makecki
5047 (johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.
5049 * doc/m4.texinfo (Eval): Added documentation for multiple
5050 precision arithmetic library support.

5062 patch from Mike Howard <mike@clove.com>
5064 1998-08-06 René Seindal <rene@seindal.dk>
5066 * gettext.m4: corrected AM_WITH_NLS to handle use of installed

5073 * src/m4.h: Added ifdef ENABLE_NLS around include of <libintl.h>
5074 and _ macro. M4 now builds with --disable-nls.
5076 * src/m4.c (main): reintroduced textdomain(PACKAGE) to get gettext
5077 to look for right message catalogs. Call indef'ed by ENABLE_NLS.
5079 * configure.in (ALL_LINGUAS): Added complete list of translations:
5080 de fr it ja nl ru sv.
5082 1998-05-22 Erick Branderhorst <Erick.Branderhorst@asml.nl>

5088 * src/Makefile.am: CFLAGS = -Wall @CFLAGS@.
5090 * checks/Makefile.am: explicit list tests in CHECKS.
5092 * configure.in, {,src,doc,lib,examples,checks}/Makefile.am,

5184 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
5185 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
5186 defines __STDC__ to 0, for indicating it is *not* ANSI!
5187 Reported by Kaveh R. Ghazi.

5206 of $U, put underline in extensions rather than in basenames. Use
5207 implicit rules, now that regularity makes this possible.
5208 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
5209 of ansi2knr whenever it is needed.
5210 * configure.in: Adjusted for correct STACKOVF substitution.
5211 * src/debug.c (trace_format): When not __STDC__, use (...) as a

5260 1994-09-23 François Pinard <pinard@iro.umontreal.ca>
5262 * src/stackovf.c: Declare the handler_t typedef earlier in the

5265 casting sigsegv_handler.
5266 Reported by Robert Bernstein.
5268 * src/m4.c (main): Initialize program_name to argv[0] without

5275 Reported by Karl Berry.
5277 1994-09-14 François Pinard <pinard@iro.umontreal.ca>
5279 * lib/Makefile.in (mostlyclean): Added.
5280 (TAGS): Make in $(srcdir).
5282 * configure.in: Use `choke me' in test, like everywhere!
5284 * {doc,examples,lib,src}/Makefile.in (check): Deleted, as
5285 unreacheable and useless.
5287 * doc/Makefile.in (texclean): Deleted, merged in mostlyclean.
5289 * lib/Makefile.in (DISTFILES): Distribute TAGS.
5290 (distclean): Do not remove TAGS.
5291 (realclean): Remove it.
5292 * Makefile.in: Make TAGS in lib also, not just in src.
5293 Reported by Karl Berry.
5295 * Makefile.in (distclean, realclean): Instead of recursively
5296 calling $(MAKE) for the -local part, allow parallel execution of
5297 -recursive and -local, only delay the removal of config.status,
5298 which is repeated in both goals.
5300 1994-09-13 François Pinard <pinard@iro.umontreal.ca>
5304 * Makefile.in: Group all *clean-recursive goals in one, using sed
5305 to remove `-recursive' while calling make recursively. Also, use
5306 a subshell for each recursive $(MAKE).
5307 Reported by Jim Meyering.
5309 * src/m4.h (memcpy): Define with bcopy for BSD systems.
5310 Reported by Kaveh R. Ghazi.
5312 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
5313 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
5316 * configure.in: Use date instead of touch for stamp-h.
5317 * Makefile.in (stamp-h.in): Idem.
5319 * Makefile.in (distclean, realclean): Force serial execution of
5320 both goals, in case parallel makes are being used.
5321 Reported by Jim Meyering.
5323 * src/Makefile.in (DISTFILES): Distribute TAGS.
5324 (distclean): Do not remove TAGS.
5325 (realclean): Remove it.
5326 Reported by Karl Berry.

5333 1994-09-08 François Pinard <pinard@iro.umontreal.ca>
5335 * Makefile.in (MDEFINES): Remove INSTALL substitutions, for
5336 ./install.sh will not be correctly referred to in sub-Makefiles.
5337 Reported by John David Anglin.
5339 * doc/Makefile.in (texclean): Remove *.cps and *.fns too.
5340 Reported by Eric Backus.
5342 * Makefile.in, checks/Makefile.in, doc/Makefile.in,
5343 examples/Makefile.in, lib/Makefile.in, src/Makefile.in: Limit

5352 care of systems having only incomplete implementations (like for
5353 Pyramid 9820 OSx 5.0d).
5354 Reported by Kaveh R. Ghazi.
5356 * src/Makefile.in (TAGS): Remote -t from etags call.
5358 1994-09-02 François Pinard <pinard@iro.umontreal.ca>
5360 * lib/Makefile.in (install): Depend on all.
5362 1994-08-31 François Pinard <pinard@iro.umontreal.ca>

5368 Reported by Jim Meyering.
5370 Solidify frozen files with respect to -P:
5371 * src/m4.c: Have -P set prefix_all_buitins variable instead of
5372 calling a function by that name. Declare the variable.
5373 * src/m4.h: Adjust declaration for prefix_all_buitins.
5374 * src/builtin.c (builtin_init): Merge in functionality from
5375 previous prefix_all_buitins function, while making entries in the
5376 symbol table, but not modifying the builtin description itself.
5378 * src/freeze.c (reload_frozen_state): Add a useless `break;',
5379 because *many* compilers do not accept an empty `default:'.
5380 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
5381 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
5383 * configure.in: Use AC_TYPE_SIGNAL.
5384 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.
5385 Reported by Robert Bernstein.

5388 m4 in the src directory.
5389 * Makefile.in (check): Don't.
5390 Reported by Akiko Matsushita and Jim Meyering.
5392 * src/output.c (make_room_for, output_character_helper): New
5393 functions, for implementing a global MAXIMUM_TOTAL_SIZE instead of
5394 a per buffer MAXIMUM_BUFFER_SIZE.
5396 * src/output.c (output_text): New function, for optimizing the
5397 output of strings of characters. Use it.
5399 1994-08-30 François Pinard <pinard@iro.umontreal.ca>
5401 * doc, src: New directories reorganizing the distribution.
5402 * doc/Makefile.in, src/Makefile.in, examples/Makefile.in: New
5404 * Makefile.in: Adjusted.
5405 * configure.in: Configure new Makefiles.
5407 * m4.h: Declare STRING typedef. Use it for comment and quote
5408 strings, adjusting all references. (This is the rudiments of a
5409 beginning for the eventual withdrawal of NUL terminated strings.)
5410 * output.c (shipout_text): Accept a length parameter, and use it.
5411 All callers adjusted.
5413 1994-08-29 François Pinard <pinard@iro.umontreal.ca>
5415 * m4.h: Include <unistd.h> if it exists.
5416 * stackovf.c: Don't.
5418 Clean up for current_diversion variable:
5419 * output.c: Move current_diversion from builtin.c.
5420 * m4.h: Declare current_diversion so builtin.c can access it.
5421 * output.c (output_init, make_diversion): Initialize or update
5423 * builtin.c (builtin_init, m4_divert): Leave current_diversion

5428 (output_init): Allocate only diversion 0.
5429 (make_diversion): Allocate new diversions as needed.
5430 * m4.h, m4.c: Remove NDIVERSIONS and ndiversion related stuff.
5431 * m4.c: Still accept -N, but do nothing with it.
5432 Reported by David MacKenzie.
5435 * output.c (freeze_diversions): New function.
5436 * m4.h: Declare freeze_diversions.
5437 * freeze.c: Document frozen file format, revise it, call
5438 freeze_diversions to add diversions to frozen format, and code to
5439 reload them properly.
5440 * m4.c: Do not undivert automatically at end when status being
5441 frozen. Do not call builtin_init when reloading frozen state.
5443 Speed up diversion processing:
5444 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
5445 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
5446 structure and variables, cached variables out of output_diversion,
5447 reallocate_diversion_for and OUTPUT_CHARACTER.
5448 (shipout_text, make_diversion, insert_diversion): Adapted to new
5450 (insert_file): Use better buffering.
5451 Reported by David MacKenzie.

5455 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
5456 dist works from another build directory.
5458 1994-08-27 François Pinard <pinard@iro.umontreal.ca>
5460 * symtab.c (hack_all_symbols): Use hash_table_size instead of
5461 constant HASHMAX, for -H option to work better.
5463 * builtin.c (DECLARE): Simplify by using _ ().
5465 * freeze.c: New file.
5466 * Makefile.in: Compile it, distribute it.
5467 * m4.c: Recognize, document and process --freeze-state (-F) and
5468 --reload-state (-R) options. Pass a true flag to builtin_init
5469 only if no reloading some state.
5470 * builtin.c (define_builtin): Remove static specifier.
5471 (find_builtin_by_name): Remove static specifier.

5484 1994-08-15 François Pinard <pinard@iro.umontreal.ca>
5486 * m4.c (long_options): Use "error-output", the dash was missing.
5487 Reported by Akiko Matsushita.
5489 1994-08-12 François Pinard <pinard@iro.umontreal.ca>
5491 * m4.h: Include <sys/types.h>.
5492 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
5493 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
5495 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
5497 * builtin.c (dump_args): Declare len as size_t, not int.
5499 * debug.c: Prototype the forward declaration of debug_set_file.
5501 * builtin.c (m4_undivert): Replace div by file, for avoiding the
5502 shadowing of this variable.
5503 * output.c (insert_diversion): Idem.
5505 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
5506 (input_init): Duplicate default quote and comment strings.
5507 (set_quotes): Free previous quote strings in all cases. Duplicate
5508 even default quote strings.
5509 (set_comment): Free previous comment strings in all cases.
5510 Duplicate even default comment strings.

5513 * Makefile.in (distclean-local): Also delete config.cache.
5515 * m4.c (usage): Reorganize the --help output by topic. Include a
5516 description for debugging flags.
5518 1994-07-29 François Pinard <pinard@iro.umontreal.ca>
5520 * configure.in: If sigaction is available and SA_ONSTACK defined,
5521 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
5522 defined, use sigvec. Else don't compile stackovf.c.
5523 * stackovf.c (setup_stackovf_trap): Idem.
5524 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
5527 1994-07-21 François Pinard <pinard@iro.umontreal.ca>
5529 * m4.c (usage): Replace printf par fputs.
5531 1994-07-18 François Pinard <pinard@iro.umontreal.ca>
5535 1994-07-17 François Pinard <pinard@iro.umontreal.ca>
5537 * configure.in: Check for sigaction and sigvec. Add a new delayed
5538 check for RLIMIT_STACK, combine in the checking for getrlimit.
5539 All those things are not universally available.
5540 * stackovf.c: Split setting up the trap handler and catching
5541 signals, for better taking care of various configure outcomes.
5542 * examples/stackovf.sh: Correct a typo.
5543 Reported by Eric Backus, Jim Avera and Jim Meyering.
5545 1994-07-16 François Pinard <pinard@iro.umontreal.ca>
5547 * ansi2knr.c: New version sent by its author, Peter Deutsch.
5549 1994-07-15 François Pinard <pinard@iro.umontreal.ca>
5551 * Makefile.in: Modify so parallel make will not try making
5552 lib/libm4.a twice simultaneously.
5553 Reported by Jim Meyering.
5555 1994-07-14 François Pinard <pinard@iro.umontreal.ca>
5557 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
5558 error message, for when no code possibility exists. Even if this
5559 line is completely #ifdef'ed out, it brings a syntax error.
5560 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
5562 * Makefile.in (install): Have install depend on all too, for lib
5563 to be remade as needed.
5565 * examples/stackovf.sh: Try ksh, bsh and bash for shells
5566 providing ulimit, instead of using only ksh.
5567 Reported by Jim Avera and Joseph E. Sacco.
5569 1994-07-12 François Pinard <pinard@iro.umontreal.ca>
5571 * Makefile.in (check): Have it depend on all instead of m4. In
5572 this way, a change in lib will be detected and processed.
5574 * builtin.c (numeric_arg): Use strtol and verify the conversion,
5575 instead of using sscanf which stops as soon as there is a
5576 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
5577 and divert(1xyzzy) were all accepted without any warning or error
5579 * m4.h: Declare strtol as long if not including stdlib.h.
5580 * configure.in: Check for limits.h, and replace strtol if missing.
5581 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
5582 * lib/strtol.c: New file, from elsewhere.
5583 Reported by Andreas Schwab.
5585 1994-07-07 François Pinard <pinard@iro.umontreal.ca>
5587 * macro.c (expand_macro): Cast value to (boolean) prior to
5588 assigning it to traced.
5589 Reported by Tom McConnell.
5591 * Makefile.in (m4): Always make all in lib first.
5592 Reported by Jim Meyering.
5594 1994-07-06 Jim Avera <jima@netcom.com>
5596 * stackovf.c: Isolated OS-dependent sections; Improved portability,
5597 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
5598 handlers), and a default error message if the fault address is not
5599 available (when neither siginfo.h nor BSD sigcontext are supported).
5600 * configure.in: Changes for stackovf.h: Check for sigcontext,
5601 sigaction, sigstack, and define rlim_t as int if necessary.
5602 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
5603 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
5604 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
5606 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
5608 * configure.in: Use AC_SET_MAKE.
5609 * Makefile.in: Use @SET_MAKE@.
5610 Reported by Jim Meyering.
5612 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
5613 Reported by Ian Taylor.
5615 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
5617 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
5618 because siginfo.h is unrelated to standard headers, and siginfo.h
5619 is already checked for.
5620 Reported by Joseph E. Sacco.
5622 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
5624 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
5627 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
5629 * builtin.c (substitute): Use \& to represent this part of the
5630 string which was matched by the whole regexp, instead of
5631 representing the whole string. Any usage of \0 issues a warning
5632 and acts like \&, it will disappear in some subsequent release.
5634 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
5636 * m4.c: Complete prototype for forwarded declaration of usage.
5638 * input.c (init_macro_token): Correct own reference in error
5639 message. Previous name get_macro_func was referred to instead.
5640 (next_char): Correct own reference in error message. Previous
5641 name advance_input was referred to instead.
5643 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
5644 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
5645 and_term, not_term, logical_not_term, cmp_term, shift_term,
5646 add_term, mult_term, exp_term, unary_term, simple_term): Add
5647 prototype to forwarded declarations. Declare parameter v1 as
5648 eval_t * instead of int *. Same for local variable v2 in dyadic
5649 functions. Same for result in exp_term.
5650 * builtin.c (m4_eval): Declare value as eval_t instead of int.
5651 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
5652 unsigned_eval_t instead of unsigned int. Change casts accordingly.
5653 (shipout_int): Cast first argument of ntoa to eval_t.
5654 Reported by Thorsten Ohl.
5656 * macro.c: Complete the prototypes of forwarded expand_macro and
5658 Reported by Thorsten Ohl.
5660 * m4.h: Define voidstar as void * or char * depending on __STDC__.
5661 The Ultrix 3.1 compiler cannot do much with void pointers.
5663 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
5664 * m4.c (xfree): Replace void * by voidstar.
5665 Reported by Tom McConnell.
5667 * ansi2knr.1: New, from elsewhere.
5668 * Makefile.in (DISTFILES): Distribute ansi2knr.1
5670 * Makefile.in (stamp-h.in): Avoid running ./config.status if
5671 stamp-h does not exist yet. This avoids running it a second time
5672 just after the initial ./configure.
5673 Reported by David MacKenzie and Tom McConnell.
5675 * m4.h: Replace the enum debug_info declaration with a series of
5676 #define's. The Ultrix 3.1 compiler would otherwise need casting
5677 (int) to most references, when used in expressions.
5678 Reported by Tom McConnell.
5680 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
5682 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
5683 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
5684 calls the compiler. Previously, FP_PROTOTYPES was only calling
5685 the preprocessor; by not being subject to CFLAGS, this was
5686 discouraging those flags asking for ANSI compilation.
5687 * acconfig.h: Document HAVE_PROTOTYPES.
5688 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
5689 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
5690 Reported by Eric Backus.
5692 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
5693 from the environment. Default CFLAGS to -g if not set.
5694 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
5695 * lib/Makefile.in: Have CFLAGS substituted from configure.
5696 Reported by Eric Backus and Tom McConnell.
5698 * configure.in: m4_undefine changeword before using AC_ENABLE.
5700 * m4.h: Declare prototypes for error (for ANSI compilers only),
5701 prefix_all_builtins and reference_error.
5702 Reported by Tom McConnell.
5704 * input.c (set_word_regexp): Do not try to initialize the array
5705 test from a string, this does not work with non-ANSI compilers.
5706 Reported by Eric Backus.
5708 * Makefile.in (dist): Clean examples/ before saving it.
5709 (distclean-local): Also remove stamp-h.
5710 Reported by Eric Backus.
5712 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
5714 Reported by Tom McConnell.
5716 * checks/Makefile.in (clean): Depends on mostlyclean.
5717 (mostlyclean): New goal.
5719 1994-06-24 François Pinard <pinard@iro.umontreal.ca>
5721 * Makefile.in (DISTFILES): Distribute install.sh.
5722 * install.sh: New file, copied from elsewhere.
5723 Reported by Assar Westerlund and Kaveh R. Ghazi.
5725 1994-06-23 François Pinard <pinard@iro.umontreal.ca>
5727 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
5728 * acconfig.h: Explain ENABLE_CHANGEWORD.
5730 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
5731 from code provided by Pete Chown]
5732 * m4.h: Add original_text field to u_t variant of union u.
5733 Declare TOKEN_DATA_FUNC macro.
5734 * builtin.c: Declare changeword.
5735 (m4_changeword): New function.
5736 * input.c: Include "regex.h", define variables with word regexps.
5737 (input_init): Initialize the word regexp.
5738 (set_word_regexp): New.
5739 (next_token): Declare local variables, use the previous code if
5740 default_word_regexp is true. Else, match using a new code. Save
5742 * macro.c (expand_token): Ship out original text if not a macro
5744 Reported by Krste Asanovic and Pete Chown.
5746 [These modifs all depend upon ENABLE_CHANGEWORD]
5747 * m4.h: Declare external user_word_regexp.
5748 * m4.c: Declare user_word_regexp, and initialize it from
5749 --word-regexp or -W, or NULL if not specified.
5750 * input.c: Use user_word_regexp if specified, instead of
5751 DEFAULT_WORD_REGEXP.
5753 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
5756 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
5757 * checks/Makefile.in: Empty the suffix list.
5758 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
5760 * m4.c: Declare nesting_limit and initialize it to 250.
5761 Implement -LNUMBER or --nesting-limit=NUMBER to change its
5763 * m4.h: Declare nesting_limit as external.
5764 * macro.c (expand_macro): Stop execution whenever nesting limit
5766 Reported by Bengt Mertensson.
5768 * eval.c (evaluate): Diagnose excess characters in eval input.
5769 Things like `eval(08)' used to return 0 with no diagnostic.
5771 * m4.h: Capitalize first letter of all macro arguments in
5774 * m4.c: Declare warning_status, initialize it to 0. Add new
5775 option -E, or --fatal-warnings, which sets warning_status to
5776 EXIT_FAILURE instead.
5777 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
5778 EXIT_FAILURE if not otherwise done by header files.
5779 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
5780 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
5781 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
5782 argument of all M4ERROR calls.
5783 Reported by Noah Friedman.
5785 * examples/incl-test.m4: Renamed from incl_test.m4.
5786 * examples/include.m4: Include incl-test.m4 instead of
5788 * examples/multiquotes.m4: Renamed from multi-quotes.m.
5790 1994-06-22 François Pinard <pinard@iro.umontreal.ca>
5792 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
5793 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
5794 also tested it on a Sun Sparc workstation running SunOS 4.x.
5796 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
5797 49.format check, abusing a `union values' argument with sprintf
5798 without selecting the proper field. Now, save the formatting type
5799 first, delaying the fetch of the corresponding argument.
5800 Reported by Joseph E. Sacco and Tom Quinn.
5802 * format.c (format): Remove const from char *fmt declaration when
5803 not HAVE_EFGCVT, because a NUL may be forced into it.
5805 * m4.h: Declare atof() when not STDC_HEADERS.
5806 Reported by Joseph E. Sacco.
5808 * Regenerate configure using Autoconf 1.11, this corrects a

5828 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
5829 * m4.h: Declare setup_stackovf_trap().

5845 of `if ... else /* nothing */' for if macros.
5846 Reported by Jim Meyering.
5848 * builtin.c (m4_regexp): Reorganize the code for avoiding a
5849 warning from gcc about `repl' possibly used before defined.
5850 Reported by Jim Meyering.
5852 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
5853 Reported by Jim Meyering.
5855 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
5857 * m4.h: Move the conditional definition of volatile after the
5858 inclusion of system files, because they may define it first.
5860 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
5862 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
5863 get around a problem with Alpha make seeing a syntax error, there.

5887 syserr() macro. Delete errref, add reference_error and M4ERROR.
5888 * m4.c: Replace errref, which was returning an input reference
5889 string, with reference_error, which prints it on standard error.
5890 * builtin.c, output.c: Use errno as second parameter to error,
5891 instead of using syserr() with %s.
5892 * *.c: Use M4ERROR instead of error: no more errref() with %s.
5893 Doing so, the program name appears after the input reference
5894 instead of before, which eases M-x next-error processing.
5896 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
5898 * checks/get-them: Escape braces with backslashes in patterns,
5899 because HPUX-9.01 awk needs this.

5935 * input.c (input_init): Initialize quote and comment strings
5936 explicitely instead of calling set_quotes and set_comment: by

5940 expected is on the left and the obtained on the right.
5942 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
5943 macros. Delete declarations for m4error, warning, fatal and
5944 internal_error, add declaration for error_message_prefix.
5945 * m4.c: Delete m4error, warning, fatal and internal_error
5946 routines, add error_message_prefix routine.
5947 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
5948 warning with WARNING*, fatal with FATAL* and internal_error with
5950 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
5951 this is not needed anymore.
5953 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
5954 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
5955 and debug_message, add declaration for debug_message_prefix.

5966 (trace_format): Use stdarg instead of varargs if __STDC__.
5968 * configure.in: Remove checks for vfprintf and _doprnt. These
5969 implementations use varargs tricks which are not portable enough.

5992 Reported by Joel Sherrill.
5994 * builtin.c (prefix_all_builtins): Instead of the table size, use
5995 the null entry at end for stopping the loop. It was overwritten.

6255 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
6257 * m4.h: Do not define index/rindex if already defined. If
6258 FALSE/TRUE are already defined, do not redefine them, but merely
6259 define boolean typedef to int.
6261 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
6262 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
6263 because some C compilers do not like connectives with #ifdef.

6265 __GNUC__ and once for __STDC__.
6266 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
6268 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
6269 Makefile dependencies. Without it, make keeps destroying and
6270 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
6272 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
6273 to diversion/DIVERSION, this was a spelling error.
6275 * m4.c: Declare version[], remove #include "version.h".

6277 * Makefile.in: Remove references to version.h.
6279 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
6280 production, by using a simpler and more robust algorithm. This
6281 solves the problem of synclines sometimes written in the middle of
6282 an output line. Delete sync_line() and output_lines variable.
6283 * m4.h: Remove sync_line prototype and output_lines declaration.
6284 * input.c (next_char), output.c (shipout_text): Remove references
6286 * input.c (push_file, pop_file): Merely put the value -1 in
6287 output_current_line instead of calling sync_line, for delaying a
6288 single `#line NUM FILE' before next output line. Do not test
6289 for sync_output, because this is unnecessary clutter.
6290 * output.c (make_divertion, insert_divertion): Idem.
6291 * input.c: Rename must_advance_line to start_of_input_line, for
6294 * debug.c (trace_header): Select a new debug line format, which
6295 better complies with GNU standards for formatting error messages.
6296 With option `-dfl', M-x next-error might be used on the output.
6297 * m4.c (vmesg): Adjust format of error output to GNU standards.
6298 * m4.texinfo: Adjust examples for `make check' to work.
6300 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
6301 case for enum debug_info constants, which were all lower case.
6303 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
6305 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
6306 collected patches. I tried a few times using newer regex.[ch], it
6307 mysteriously stopped aborting with this one. Insecure feeling...
6308 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
6310 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
6312 * m4.c: Change `--no-warnings' to `--silent'.
6313 Reported by David MacKenzie.
6315 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
6316 leave it off for now. See comment in m4.c for justification.
6317 Reported by David MacKenzie.
6319 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
6320 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
6322 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
6324 * Makefile.in: Ensure recursive cleaning is done before local
6325 cleaning for all clean goals.
6327 * builtin.c (ntoa): Ensure the value is always interpreted as a
6328 signed quantity, whatever the radix is.
6330 1992-11-18 Jim Meyering <meyering@idefix>
6332 * builtin.c, format.c, input.c: Split long lines.
6333 * m4.c: Use typedef macro_definition instead of struct
6335 * symtab.c: Use typedef symbol instead of struct symbol.
6337 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
6339 * *.[ch]: Remove all trailing whitespace, in code and comments.
6341 * configure.in: Find some awk.
6342 * Makefile.in: Add $(AWK) to MDEFINES.
6343 * checks/Makefile.in: Transmit $(AWK) to get_them.
6344 * checks/get_them: Use $AWK instead of gawk. Add a close in the
6345 awk script when switching files, because without this, mawk runs
6346 out of file descriptors.
6348 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
6350 * Makefile.in (realclean): Delete m4.info*.
6351 Reported by Jim Meyering.
6353 * Makefile.in: Adjust and link with checks/Makefile.
6354 * checks/Makefile.in: New.
6355 * configure.in: Output checks/Makefile.
6357 * checks/get_them: Have the dnl header of each test more
6358 recognizable by next-error, also use a better message.
6360 1992-11-16 Jim Meyering <meyering@idefix>
6362 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
6363 And use that only if __GNUC__ since we're using it's GCC-specific
6364 semantics that tell the compiler the associated function doesn't
6367 * builtin.c (substitute): Don't use character as an array index.
6368 (dumpdef_cmp): Make formal arguments `const void *' to avoid
6369 warnings with gcc -W -Wall on systems with qsort prototype.
6370 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
6373 * eval.c (most functions): Add parentheses to assignments used
6374 as truth values go avoid warnings from gcc -Wall.
6376 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
6377 any functions that don't need external scope.
6379 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
6380 (many functions and arrays): Declare `const'.
6382 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
6384 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
6385 removing the declaration from m4.h. Also rename false to FALSE
6388 * lib/Makefile.in (Makefile): New goal.
6390 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
6391 so heavily loaded. It gets more easily overridable, calling make.
6392 Reported by Jim Meyering.
6394 * Makefile.in (dist): Get .fname from the current directory name,
6395 instead of from version.h. I need updating many files manually,
6396 when the version changes, version.h is just one of them.
6398 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
6400 * m4.h: Remove the tag `boolean' on the enum introducing typedef
6401 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
6402 Reported by Tom McConnell.
6404 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
6406 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
6407 39.cleardiv, which were describing missing or spurious newlines.
6408 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
6409 do not depend on machine word size, `/bin/false' implementation,
6410 or `wc' output format. `make check' is more dependable, now.
6412 * checks/check_them: Summarize the failed tests by listing their
6413 name, at end. If none, issue `All checks successful'. Output
6414 `Checking' instead of `Input file:'.
6416 * checks/get_them, checks/check_them: Reindented.
6418 * Makefile.in (dist): chmod a+r before making the tar file.
6420 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
6422 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
6424 * input.c (next_token): Reinitialize token_buttom just after using
6425 it as a watermark with obstack_free. Or else, a future token, big
6426 enough for triggering reallocation of the obstack chunk, could
6427 void the initialized value of token_buttom, later causing panic in
6428 obstack_free. Rename token_buttom to token_bottom everywhere.
6430 * m4.h: Before declaring errno, first include <errno.h> and
6431 ensure that it does not define errno.
6432 Reported by Richard Stallman.
6434 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
6436 * builtin.c: Define and use DECLARE macro for builtins.
6438 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
6439 argument, this is a common idiom for introducing long comments.
6441 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
6442 arguments. The last argument was silently ignored.
6444 * m4.c (cmd_error): Add a missing semicolon before va_end().
6446 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
6448 * Makefile.in: Now handle protoized sources. Define and use U.
6449 Compile and use ansi2knr with old compilers. Update DISTFILES.
6450 Add `aclocal.m4' to `configure' dependencies.
6451 * ansi2knr.c: New, from Ghostscript distribution.
6452 * configure.in: Define U through FP_PROTOTYPES for old compilers.
6453 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
6454 * aclocal.m4: New, provide FP_PROTOTYPES.
6455 * m4.h: Conditionnaly protoized through Args, save for varags.
6456 * builtin.c: Protoized. Then:
6457 Include <sys/types.h> if size_t is not defined, before "regex.h".
6458 (m4_ifelse): Fetch built-in name properly for diagnostic.
6459 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
6460 (m4_regexp): Add const to `msg' declaration.
6461 (m4_patsubst): Add const to `msg' declaration.
6462 * debug.c: Protoized, save for varargs.
6463 * eval.c: Protoized.
6464 * format.c: Protoized.
6465 * input.c: Protoized.
6466 * m4.c: Protoized, save for varargs. Then:
6467 (xfree): Accept void * instead of char *.
6468 (xmalloc): Return void * instead of char *.
6469 (xrealloc): Accept and return void * instead of char *.
6470 * macro.c: Protoized.
6471 * output.c: Protoized.
6472 * path.c: Protoized. Then cast some (char *) over xmalloc's.
6473 * symtab.c: Protoized.
6475 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
6477 * m4.texinfo: Remove directory from diagnostics in 30.include,
6478 51.eval, 56.errprint and 57.m4exit tests.
6480 * m4.h: Remove declarations for int or void system functions, they
6481 cause more conflicting trouble than they make good.
6483 * configure.in: Avoid configuration header file. Add some tests.
6484 * m4.h: Remove #include "config.h".
6485 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
6486 Then, rewritten for better compliance with GNU standards.
6488 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
6490 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
6491 because of a misplaced #endif.
6493 * Many *.[hc] files: Correct intra-line spacing here and there,
6494 according to GNU indent 1.6 advice.
6496 * configure.in: New, using Autoconf 1.2.
6497 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
6498 * Delete old configure.in, configure, etc/configure.in,
6499 etc/configure, lib/configure.in, lib/configure and config/*.
6500 Reported by Jason Merrill.
6502 * symtab.c (hash): Change (char) NULL to '\0'.
6503 Reported by Jason Merrill.
6505 * Delete .vers, etc/newdist.sh, etc/newvers.sh and

6520 1992-03-10 François Pinard <pinard@iro.umontreal.ca>
6522 * Makefile.in (check): Add m4 as dependency.
6524 * m4.c: Accept --no-warnings instead of --no_warnings, and
6525 --no-gnu-extensions instead of --no_gnu_extensions. Make the

6549 Reported by Michael Fetterman.
6551 * eval.c, input.c, m4.h: Remove last comma in enums.
6552 Reported by Mike Lijewski.
