110 The regs_allocated field in a struct re_pattern_buffer refers
111 to the state of a particular re_registers struct when used in
112 successive matches using the same compiled pattern. Avoid a
113 SEGV in `renamesyms' resulting from using a new re_registers
114 with an existing re_pattern_buffer:
116 * modules/gnu.c (m4_pattern_buffer): Wrapper struct for associated
117 pattern buffer and registers.
118 (m4_regexp_search): New function to call re_regexp_search with

145 * Makefile.am (src_m4_DEPENDENCIES): Make dependency explicit.
146 (clean-local): Split into and depend upon...
147 (clean-local-tests, clean-local-src): ...these two. The latter
148 removes the libtool object directory below `src', to work around

150 (EXTRA_DIST): Distribute modules/perl.c.
152 2006-06-19 Eric Blake <ebb9@byu.net>
154 * Makefile.am ($(srcdir)/doc/m4.1): No need to list $(srcdir) in

157 (EXTRA_DIST): Distribute stamp-vcl.
158 Reported by Ralf Wildenhues.
159 (TESTSUITE): Revert earlier change that used absolute path, as
160 that broke 'make dist' in VPATH. Stick with $(srcdir) instead.
161 (EXTRA_DIST): Revert earlier change of $(TESTSUITE).

165 path to testsuite here, rather than relative path to testsuite
168 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
170 * m4/m4private.h (DELETE): Cast away const here...

217 * Makefile.am (src_m4_CPPFLAGS): Use STACKOVF as a makefile
219 * ltdl/m4/m4-gnulib.m4: Delete, no longer needed.
221 Reduce compiler warnings. Inside GMP, mpq_t is an array type, so

223 type-punning warnings caused trying to mix these types.
224 * modules/mpeval.c (numb_ior, numb_eor, numb_and, numb_lshift),

266 * configure.ac (AC_CHECK_FUNCS): Remove obsolete checks.
267 * Makefile.am (doc/m4.1): Depend on installed help2man, rather

300 * ChangeLog: Change encoding to UTF-8.
302 Avoid compiler warnings.
303 * m4/macro.c (trace_format): Don't mark this as a printf format,
304 since we don't accept the same set of modifiers as printf. It
305 would be nice if gcc let us specify a custom format archetype.
306 * src/main.c (main): Cast away const.
308 2006-06-10 Andreas Schwab <schwab@suse.de> (tiny change)

352 2005-12-05 Gary V. Vaughan <gary@gnu.org>
354 * bootstrap (func_update_po): Synch with CVS GNU tar. wget 1.9.x
355 and 1.10.x support --cache=off, so $WGETFLAGS are not necessary.

358 2005-12-04 Gary V. Vaughan <gary@gnu.org>
360 * bootstrap (func_update_po): Test and set $WGETFLAGS to disable

370 throughout, instead of calling obsolete lt_dlhandle_find directly.
371 (m4__module_next): Use multiloader-safe lt_dlhandle_iterate. Use

424 * tests/generate.awk: Allow some forbidden `m4_' prefixed symbols
425 to stop the new generated tests from choking.
427 2005-05-07 Gary V. Vaughan <gary@gnu.org>
429 Since most of the build is handled from a single Makefile.am now,
430 we can teach make about the dependencies between the m4 binary and
431 the preopened modules it is built against:
433 * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
435 * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
436 of the preopened modules have changed.
438 2005-05-07 Gary V. Vaughan <gary@gnu.org>
440 * configure.ac (gl_MODULES): Add mkstemp for machines that don't
441 have a native implementation.
443 2005-05-06 Gary V. Vaughan <gary@gnu.org>
445 * src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are

449 --disable-assert configure time option for NDEBUG setting.
451 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.

465 2005-05-04 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
467 Forward port of a patch that allowed m4-1.4.2 to compile on
470 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
472 * src/m4.h: And include them as appropriate.
473 * src/main.c, src/stackovf.h: Don't include signal.h literally;
474 m4.h will include the correct file.

478 * m4/m4private.h: Make errno visible for the sources patched
481 2005-05-04 Paul Eggert <eggert@twinsun.com>

490 * m4/output.c (m4_insert_file): Don't assume errno has a valid
491 value simply because fread returns zero. This fixes a
492 portability bug reported by Marion Hakanson in
493 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
495 2005-05-04 Santiago Vila <sanvila@debian.org>

502 * m4/output.c (m4_insert_file): Do not mix buffered and
503 unbuffered I/O, as this breaks on the Hurd.
505 2005-05-04 Gary V. Vaughan <gary@gnu.org>
507 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
508 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
509 and libtoolize does a better job of ltdl importing now too, so
510 take advantage of that while updating the tree:
512 * acm4, config: Moved from here...
513 * ltdl/m4, ltdl/config: ...to here.
514 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
515 src/Makefile.am, tests/Makefile.am: Removed...
516 * Makefile.am: ...and migrated to here, with adjustments to
517 compensate for relative path differences.
518 * commit: Adjust relative paths.
519 * configure.ac: Adjust relative paths.
520 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
522 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
523 the meanwhile, CVS HEAD libtool is needed.
524 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
525 stricly new enough, we also need a patch.
526 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
527 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
528 (gl_MODULES): Don't list getopt and version-etc, as they don't
530 * bootstrap: After running gnulib-tool to import the listed
531 modules, fetch getopt and version-etc into src manually.
532 (ltdldir): Change to ltdl.
533 * src/main.c: Adjust for changes in version-etc API.
534 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
535 but works when the getopt module isn't to be included in the lib.
536 * README: Add note about patching autoconf and automake to
539 2005-05-02 Matt Kraai <kraai@debian.org> (tiny change)
541 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=84416
542 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
543 empty file rather than to a nonexistent file. This closes a
544 common security hole.
545 * modules/m4.c (m4_maketemp): Implement the above, by using
546 mkstemp rather than mktemp.
548 2005-05-01 Gary V. Vaughan <gary@gnu.org>
550 The FSF are moving offices today. Changed their contact address
551 in all files from `59 Temple Place, Suite 330, MA 02111-1307' to
552 `51 Franklin Street, Fifth Floor, MA 02110-1301'.
554 2005-03-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
556 * tests/Makefile (clean-local): Ignore testsuite cleanup
559 2005-03-11 Per Bothner <per@bothner.com> (tiny change)
561 * tests/Makefile (clean-local): Only run the testsuite cleanup
562 if the testsuite has been generated.
564 2005-02-11 Stepan Kasal <kasal@ucw.cz>
566 * TODO: slight clarification of the example of qindir usage.
568 2005-02-08 Gary V. Vaughan <gary@gnu.org>

571 From Stepan Kasal <kasal@ucw.cz>
573 2005-02-08 Stepan Kasal <kasal@ucw.cz>
575 * TODO: Add ``execution stack'', fix a typo.
576 * doc/m4.texinfo: Typos.
578 2004-12-24 Eric Blake <ebb9@byu.net>
580 * configure.ac (INCLUDE_STDBOOL_H): Account for gnulib's move
581 to the gnu subdirectory.
582 * acm4/m4-error.m4 (INCLUDE_ERROR_H): Likewise.
583 * acm4/m4-obstack.m4 (INCLUDE_OBSTACK_H): Likewise.
584 * acm4/m4-regex.m4 (INCLUDE_REGEX_H): Likewise.
585 * m4/system_.h: Likewise, in non-configured includes.
587 2004-10-14 Noah Misch <noah@cs.caltech.edu>,
588 Gary V. Vaughan <gary@gnu.org>
590 * m4/m4.c (m4_context_field_table, m4_context_opt_bit_table):
591 Protect definitions from macro expansion under -DNDEBUG by
592 parenthesising the expanded function names.
593 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
594 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
595 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
596 (m4_is_syntax_macro_escaped): Similarly protect function
597 definitions from macro expansion under -DNDEBUG by #undefing the
598 matching macro names before each definition. Also, move all the
599 function definitions to the end of the file so that any
600 invocations in the rest of the file pick up the fast macro
602 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)
603 (m4_set_debug_file, m4_set_trace_messages)
604 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
605 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
606 (m4_set_max_debug_arg_length_opt): New fast macro versions of the
607 option setter functions.
609 2004-09-23 Gary V. Vaughan <gary@gnu.org>
611 * src/main.c: Include gnulib files from the correct directory.
613 * gnulib/*: Don't store any of the gnulib files in arch, as they
614 generate spurious changes.
615 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
616 gnulib macros now share our macro directory.
617 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
618 * bootstrap: Call gnulib-tool to import from the gnulib tree.
619 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
620 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
621 the gettext macros from autopoint that overwrite the gnulib-tool
622 imported versions. Import sources and Makefile.am into the `gnu'
623 directory. Changed all callers.
624 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
625 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
626 for imported modules.
627 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
628 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
629 hardcoding the gnulib macros they wrap.
631 2004-07-15 Gary V. Vaughan <gary@gnu.org>
633 Latest CVS libtool can preload modules in libraries, including
634 its own module loaders! Tweak m4 so that it doesn't try to treat
635 libltdl's module loaders as m4 modules when freezing and on exit:
637 * gnulib/acm4/*.m4: Don't store these files in arch since they
638 generate spurious changes.
639 * bootstrap: Simplify initial libtoolize call, since CVS
640 libtoolize is smarter these days.
641 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
643 * m4/module.h (m4__module_exit): Missing declaration.
644 * m4/m4private.h (m4__module_next): New function declaration.
645 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
646 encapsulation. Changed all callers.
647 (m4__module_interface): New function to verify m4 loadable module
649 (m4__module_init): Register the interface validator.
650 (m4__module_exit): Only close my own modules.
651 * modules/m4.c (unistd.h): Provide missing declaration.
652 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
653 (m4_expand_ranges): More missing declarations.
654 * modules/modtest.c (export_test): Ditto.
655 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
656 * src/main.c (main): Bump copyright year.
657 * tests/modules.at: Fix sed syntax error.
660 2004-06-17 Gary V. Vaughan <gary@gnu.org>
662 Tweaking to enable compilation with latest CVS libtool and
663 libltdl. We can't just dump the library files directly into the
664 m4 directory anymore now that libltdl is built from pieces itself:
666 * bootstrap: Rewritten to use latest libtoolize sanely, and to
667 set up libltdl subdirectory.
668 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
669 gnulib subdirectory's config.
670 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
671 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
673 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
674 configure.ac, so use AC_WITH_LTDL instead.
675 * Makefile.am (SUBDIRS): Add libltdl.
676 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
678 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
679 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
680 (libm4_la_LIBADD): Add LIBLTDL.
681 * m4/ltdl.c, m4/ltdl.h: Removed.
682 * m4/m4module.h: Include canonical ltdl.h.
685 2004-06-14 Gary V. Vaughan <gary@gnu.org>
687 * gnulib/import: Now updates makefile fragments, and configure.ac.
688 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
689 * gnulib/m4/Makefile.am: include it.
690 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
691 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
692 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
693 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
694 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
695 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,
696 gnulib/acm4/lib-ld.m4, gnulib/acm4/lib-prefix.m4,
697 gnulib/acm4/error.m4, gnulib/acm4/po.m4, gnulib/acm4/regex.m4,
698 gnulib/acm4/stdbool.m4, gnulib/acm4/stdint_h.m4,
699 gnulib/acm4/uintmax_t.m4, gnulib/acm4/ulonglong.m4,
700 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
701 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
702 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
704 * gnulib/m4/getopt_int.h: New source file from latest gnulib
706 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
707 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,
708 gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
709 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
710 Updated source files from latest gnulib.
712 2004-02-29 Gary V. Vaughan <gary@gnu.org>
714 * config/mailnotify: New file for mailing commit notifications,
715 imported from cvs-utils.
716 * commit: Updated from cvs-utils and tweaked for m4.
718 2003-12-01 Gary V. Vaughan <gary@gnu.org>
720 * config/mkstamp: Updated from CVS libtool.
721 * configure.ac: Generate a gnu coding standards compliant version
722 number, and use it for the banner.
723 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
724 mhen the TIMESTAMP changes in ChangeLog, but the file modification
725 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
726 contain the previous version number.
727 * src/main.c: Make --version output conform to the GNU standard.
729 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
730 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
731 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
732 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
733 time_la_SOURCES): ...so that these are defaulted correctly, and
734 can be removed from this file.
735 (AM_LDFLAGS): Add -module...
736 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
737 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
738 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
739 the individual settings can be removed.
740 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
741 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
742 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
743 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
744 time_la_LIBADD): ...so that these are picked up as a deplib of
745 libm4 and don't need to be set explicitly.
747 2003-11-18 Gary V. Vaughan <gary@gnu.org>
749 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
750 from the standard build. It is too fragile.
752 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
753 CVS libtool after merging m4 changes across to libtool.
755 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
756 * m4/path.c (search_path_add): Ditto.
758 2003-11-13 Gary V. Vaughan <gary@gnu.org>
760 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
761 libtool tags we don't use in configure. This reduces the size
762 of the script from over 1Mb to under 700Kb.
764 2003-11-13 Gary V. Vaughan <gary@gnu.org>
766 The import script was not written properly, and the last gnulib
767 import was incomplete. Fixed that problem, and reimport our
768 gnulib dependencies, which picks up the address calculation
769 overflow checks described by Paul below. Also tweak the clients
770 of the gnulib xalloc module not to use deprecated macros:
772 * gnulib/import: Recurse through module dependencies rather than
773 naively descending only one level.
774 * configure.ac: Add calls to gnulib's strnlen and extension module
776 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
778 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
779 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
780 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
781 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
783 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
784 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
785 place of `xcalloc (1, S)'.
786 * m4/m4.c (m4_create): Likewise.
787 * m4/m4private.h (m4_symbol_value_create): Likewise.
788 * m4/symtab.c (symtab_fetch): Likewise.
789 * m4/syntax.c (m4_syntax_create): Likewise.
790 * src/freeze.c (reload_frozen_state): Likewise.
791 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
793 * m4/symtab.c (m4_symtab_create): Likewise.
795 2003-11-13 Gary V. Vaughan <gary@gnu.org>
797 * tests/module.at: Comment typo.
799 2003-10-10 Gary V. Vaughan <gary@gnu.org>
801 * tests/modules.at (modules: importing): Apply some lateral
802 thinking, and use AT_CHECK to compare the output of a sed pass
803 over stderr against the canonical strerror string.
805 * tests/modules.at (modules: importing): Edit the generated stderr
806 output to canonicalize strerror output, before a comparison.
808 2003-10-10 Gary V. Vaughan <gary@gnu.org>
810 Tru64UNIX perl is sloppy with namespace pollution. This patch is
811 careful not to trip over the mess:
813 * modules/perl.c: Some builds of perl install headers that contain
814 `#define try __builtin_try'. Be sure to undefine that macro
815 before `m4/hash.h' gets included, which uses the `try' symbol.
816 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
817 `false' before including `stdbool.h'.
818 (DELETE): This symbol is not in m4's namespace, and is in any
819 case only used internally...
820 * m4/m4private.h (DELETE): ...so move it to here.
821 Reported by Martin MOKREJS <mmokrejs@natur.cuni.cz>
823 2003-10-08 Paul Eggert <eggert@twinsun.com>
825 Don't use XMALLOC and XCALLOC. Once we install the
826 corresponding patch into gnulib, this will fix some
827 address-calculation overflow bugs on hosts where calloc (A, B)
828 returns garbage when A*B overflows.
830 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
831 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
832 xmalloc, XCALLOC with xcalloc.
833 * m4/m4.c (m4_create): Likewise.
834 * m4/m4private.h (m4_symbol_value_create): Likewise.
835 * m4/output.c (m4_output_init): Likewise.
836 * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise.
837 * m4/syntax.c (remove_syntax_attribute): Likewise.
838 * src/freeze.c (reload_frozen_state): Likewise.
839 * src/main.c (main): Likewise.
841 2003-10-07 Gary V. Vaughan <gary@gnu.org>
843 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
844 gnulib/acm4 directories for aclocal m4 macros.
845 * gnulib/Makefile.am (EXTRA_DIST): Removed.
846 (MAINTAINERCLEANFILES): Add Makefile.in.
847 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
849 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
850 * gnulib/import: New file. Temporary script for updating gnulib
851 imported files, until gnulib-tool is working.

890 gnulib/acm4/xstrndup.m4: Reimported from CVS gnulib with

897 gnulib/m4/xalloc.h, gnulib/m4/xmalloc.c: Updated from CVS
898 gnulib with gnulib/import script.
899 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
900 guards ready for gnulib-tool to autoupdate on import.

925 * gnulib/m4/exit.h: Import exit module from CVS gnulib.
926 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
927 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
930 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
931 Gary V. Vaughan <gary@gnu.org>
933 * bootstrap: Separate options.
934 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
935 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
937 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
938 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
939 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
940 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
941 $(LTLIBINTL) for gettext support on cygwin.
942 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
943 have $(LTLIBINTL) from the preloaded module la files.
944 * README: Remove the warning about using --disable-nls on Windows
947 2003-09-15 Gary V. Vaughan <gary@gnu.org>
949 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
950 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
953 2003-09-12 Gary V. Vaughan <gary@gnu.org>
955 * doc/STYLE: Document the gnulib header naming conventions, and
957 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
958 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,
959 gnulib/m4/gettext.h, gnulib/m4/obstack.h, gnulib/m4/regex.h
961 * gnulib/m4/Makefile.am: Remove the rules to build these headers.
963 * gnulib/m4/strtol.c, gnulib/config/strtol.m4: Import strtol
964 module from CVS gnulib.
965 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
966 (gl_FUNC_STRTOL): In favour of the module macro.
968 2003-09-12 Gary V. Vaughan <gary@gnu.org>
970 Replace the getopt code with CVS gnulib getopt. The source files
971 detect whether they are in a glibc environment and preprocess away
972 all of the code if there is a system getopt, so we can compile
973 them into the m4 executable unconditionally:
975 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
976 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
977 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
979 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
981 * src/Makefile.am: Adjust.
982 * src/main.c: Always include our shipped getopt.h.
983 * po/POTFILES.in: Use new location of getopt.c.
985 2003-09-12 Gary V. Vaughan <gary@gnu.org>
987 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
988 * config/Makefile.am: Removed. Automake 1.8 distributes the files
989 in this directory automatically.
990 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
992 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
994 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
996 * modules/Makefile.am (pkglibexecdir): Set it here.
997 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
999 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
1000 Import regex module from CVS gnulib.
1001 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
1002 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
1003 do extra substitutions for Makefile.
1004 * configure.ac: Use it.
1005 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
1006 from regex_.h if necessary.
1007 * m4/system_.h: Include the correct version of regex.h.
1008 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
1010 * po/POTFILES.in: Use new location of regex.c.
1012 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
1013 realloc.c: automake distributes these files already.
1015 2003-09-12 Gary V. Vaughan <gary@gnu.org>
1017 Replace the xstrzdup code by importing the xstrndup module from
1018 CVS gnulib, along with its dependencies: strndup and strnlen:
1020 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
1021 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
1023 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
1024 gnulib/config/strndup.m4: Ditto wrt strndup.
1025 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
1027 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
1028 However, contrary to gnulib, we install xstrndup.h.
1029 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
1030 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
1031 is an artifact of the old m4 portability layer.
1032 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
1033 * m4/system_.h: Include xstrndup.h.
1034 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
1036 2003-09-11 Gary V. Vaughan <gary@gnu.org>
1038 Reimport the latest xalloc module from CVS gnulib, and adjust the
1039 m4 sources to take advantage of xalloc xfree. Also create a new
1040 macro DELETE with the same semantics as the old m4 XFREE macro,
1041 and carefully tweak callers:
1043 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
1045 * m4/utility.c (xfree): Removed. This function is now supplied by
1047 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
1048 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
1049 * m4/symtab.c (m4_symtab_create): Ditto.
1050 * m4/system_.h: Removed XFREE redefine.
1051 (DELETE): New macro with same functionality as the original m4
1052 XFREE macro, but based on xalloc.h now. Changed all callers.
1053 * src/main.c (main): Use XMALLOC macro.
1054 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
1056 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
1058 2003-09-10 Gary V. Vaughan <gary@gnu.org>
1060 Import the xalloc module from CVS gnulib, along with its
1061 dependencies: exitfail, malloc and realloc. We had different
1062 semantics for our XFREE and a function xfree() not supplied by
1063 gnulib, so also a bit of work to keep everything running
1066 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
1067 (gl_XALLOC): Use gnulib equivalents.
1068 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
1069 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
1070 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
1071 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
1073 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
1074 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
1075 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
1077 (pkgincdir): Removed. Use pkgincludedir instead.
1078 * m4/m4private.h (XFREE): xfree already checks for NULL.
1079 * m4/system_.h: Use xalloc module, and remove macros already
1080 supplied by xalloc.h.
1081 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
1082 moved the old definition from m4/xmalloc.c to here for now.
1084 2003-09-09 Gary V. Vaughan <gary@gnu.org>
1086 Import the error and progname modules from CVS gnulib. Our old
1087 error.c subsumed the functionality of both, so a little adjustment
1088 was required to accomodate the split in sources. Also added more
1089 wrapper macros to choose between a system installed error.h or our
1090 shipped gnulib error module:
1092 * m4/error.c, m4/error.h: Removed.
1093 * m4/Makefile.am: Adjust.
1094 (pkgincdir): Removed. Use pkgincludedir instead.
1095 * m4/module.h, src/main.c: Don't include `m4/error.h'.
1096 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
1098 * gnulib/m4/progname.c: Imported from CVS gnulib.
1099 * gnulib/m4/progname.h: Ditto.
1100 * src/main.c: Adjust to use progname module.
1101 * gnulib/m4/error.c: Imported from CVS gnulib.
1102 * gnulib/m4/error_.h: Ditto.
1103 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
1104 if appropriate, and link a local error.h if the system version is
1106 (libgnu_la_SOURCES) Add progname module sources.
1107 * gnulib/config/error.m4: Imported from CVS gnulib.
1108 * gnulib/config/strerror_r.m4: Ditto.
1109 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
1110 to have ERROR_H for Makefile substitutions and tell system.h
1111 whether the system error.h should be used, or a locally installed
1113 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
1115 2003-09-09 Gary V. Vaughan <gary@gnu.org>
1117 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
1118 s/gettext_.h/gettext.h/.
1120 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
1121 automake have been fixed.
1123 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
1124 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
1125 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
1126 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
1128 2003-09-09 Gary V. Vaughan <gary@gnu.org>
1130 The gnulib obstack module requires the gnulib gettext module for
1131 systems that do not have GNU gettext installed. Because we use
1132 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
1133 that directory incase it clashes with the system gettext.h. This
1134 delta uses gettext_.h and extra rules in the Makefile to make a
1135 link to gettext.h when needed:
1137 * Makefile.am (auxdir): Removed. No longer used.
1138 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
1139 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
1141 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
1142 Makefile based build.
1143 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
1144 of the macros are kept.
1145 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
1146 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
1147 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
1148 distributes these automatically.
1149 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
1150 warning from automake-1.7a.
1151 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
1152 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
1154 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
1155 wrt. m4_FUNC_OBSTACK.
1156 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
1157 wrt. m4_sys_STACKOVF.
1158 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
1159 wrt. _m4_LIB_GMP, m4_LIB_GMP.
1160 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
1161 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
1163 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
1164 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
1165 gettext.h link on deficient systems.
1166 (pkginc_HEADERS): Mention $(GETTEXT_H).
1167 (EXTRA_HEADERS): Mention gettext.h.
1168 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
1169 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
1170 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
1171 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
1172 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
1173 gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
1174 gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
1175 gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
1176 gnulib/config/po.m4, gnulib/config/progtest.m4,
1177 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
1178 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
1180 2003-09-05 Gary V. Vaughan <gary@gnu.org>
1182 We can't mirror the gnulib directory structure here, since we need
1183 to be able to eg. `#include <m4/obstack.h>' from our source files,
1184 which is much easier if the local obstack.h is created in a
1185 directory named m4. Rather than trying to symlink everything into
1186 the m4 directory, now we build a libtool convenience library from
1187 the sources we get from gnulib and link that with libm4.la:
1189 * gnulib/config/extensions.m4: Imported from CVS gnulib.
1190 * gnulib/config/unlocked-io.m4: Ditto.
1191 * gnulib/m4/unlocked-io.h: Ditto.
1192 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
1193 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
1194 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
1195 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
1196 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
1197 * m4/Makefile.am: Adjust.
1198 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
1199 macros we redistribute.
1200 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
1201 library among others.
1202 (GNULIB_SRCS, GNULIB_MACROS): Removed.
1203 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
1204 * config/m4-obstack.m4: Adjust.
1205 * po/POTFILES.in: Adjust.
1206 * configure.ac: Reformatting. Call newly imported gnulib macros.
1207 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
1208 bogus calls of `#include "m4.h"'.
1209 * Makefile.am: INCLUDES has been deprecated in favour of
1211 * m4/Makefile.am: Ditto.
1212 * modules/Makefile.am: Ditto.
1213 * src/Makefile.am: Ditto.
1215 2003-09-05 Gary V. Vaughan <gary@gnu.org>
1217 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
1219 2003-09-04 Gary V. Vaughan <gary@gnu.org>
1221 Migrate the obstack support into the gnulib directories for easy
1222 synchronisation with upstream files in gnulib:
1224 * config/gnu-obstack.m4: Moved from here...
1225 * config/m4-obstack.m4: ...to here.
1226 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
1227 * m4/obstack.c, m4/obstack_.h: Moved from here...
1228 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
1229 * po/POTFILES.in: Adjust.
1230 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
1231 * m4/Makefile.am: Add a whole new section to link the obstack
1232 sources from the gnulib tree if necessary.
1233 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
1235 * config/m4-obstack.m4: Rewrite as a wrapper for
1236 gnulib/m4/obstack.m4.
1238 2003-09-04 Gary V. Vaughan <gary@gnu.org>
1240 GNU M4 currently builds with a number of files adapted from
1241 upstream sources. Recently the gnulib project on savannah.gnu.org
1242 has pulled together a great many of these externally maintained
1243 files. This delta is the beginnings of isolating those files
1244 maintained in gnulib to make it easy to synchronise M4 with the
1245 upstream files prior to releases.
1247 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
1249 (SUBDIRS): Added new gnulib subdirectory.
1250 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
1251 * config/stdbool.m4: Moved from here...
1252 * gnulib/m4/stdbool.m4: ...to here.
1253 * m4/stdbool_.h: Moved from here...
1254 * gnulib/lib/stdbool_.h: ...to here.
1255 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
1257 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
1258 code to work with new stdbool_.h location.
1259 (gnulib_srcdir): New.
1261 2003-09-04 Gary V. Vaughan <gary@gnu.org>
1263 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
1264 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
1266 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
1267 (EXTRA_DIST): Use it.
1269 * bootstrap: CVS autoreconf leaves file droppings. Remove
1270 aclocal.m4t incase autoreconf doesn't.
1272 2003-08-29 Gary V. Vaughan <gary@gnu.org>
1274 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
1275 the other gnulib imports, renamed to m4/obstack_.h.
1276 * m4/obstack.c: Updated from CVS gnulib.
1277 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
1278 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
1279 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
1280 about vpath already, and $top_srcdir upsets CVS Automake, so the
1281 $top_srcdir reference was removed.
1283 * m4/system-h.in: For consistency with the gnulib imports, renamed
1285 * m4/Makefile (EXTRA_HEADERS): Adjust.
1286 * configure.ac (AC_CONFIG_FILES): Adjust.
1288 * m4/stdbool_.h: New file from gnulib for systems without their
1290 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
1291 * config/stdbool.m4: New file. Macros from gnulib for same.
1292 * configure.ac: Use it.
1294 2003-08-27 Gary V. Vaughan <gary@gnu.org>
1296 * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'`

1343 * src/main.c: Ditto.
1344 * src/stackovf.c: Ditto.
1346 * config/gmp.m4 (M4_AC_LIB_GMP): Use AC_INCLUDES_DEFAULT:
1347 ac_default_headers is an autoconf internal variable.
1348 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
1349 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
1351 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
1352 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
1355 2003-08-15 Gary V. Vaughan <gary@gnu.org>
1357 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
1359 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
1360 possible or faking one with a typedef. Changed all callers.
1362 2003-08-15 Gary V. Vaughan <gary@gnu.org>
1364 Still cleaning up the users' module API, by taking out the stuff
1365 that isn't used by any existing modules, and moving specialised
1366 functions out of libm4 and into the module they are used by.
1368 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
1369 * m4/utility.c (m4_skip_space): ...to here the home of its only
1370 use, made static and renamed to `skip_space'. Changed all
1372 * m4/m4module.h (m4_expand_ranges): Removed prototype.
1373 * m4/utility.c (m4_expand_ranges): Moved definition from here...
1374 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
1376 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
1378 * modules/gnu.c (builtin_syntax): Import and use in this
1379 builtin implementation.
1380 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
1382 * m4/macro.c (trace_flush): Except here where the macro is now
1384 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
1385 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
1387 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
1388 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
1390 2003-08-14 Gary V. Vaughan <gary@gnu.org>
1392 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
1393 compiler based AC_CHECK_HEADER that was introduced in
1395 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
1396 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
1397 * configure.ac: Use renamed M4_AC_LIB_GMP.
1399 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
1400 macro that requires arguments! This stops the shell's bad
1401 substitution error at configure time.
1403 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
1404 variables to the testsuite shell. Set the value of USE_GMP so
1405 that the gmp test will run!
1406 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
1408 2003-08-11 Gary V. Vaughan <gary@gnu.org>
1410 Libltdl already has an excellent mechanism for accessing C symbols
1411 in modules. Lets use that! Remove all the exporting cruft and
1412 just use lt_dlsym in conjunction with a few conventions to
1413 simplify module writers' jobs. Also removed the table address
1414 caching code and otherwise simplified the module loader quite a
1415 bit. To access exported symbols in other modules, first the
1416 exporting module must name the symbols <modname>_LTX_<symname>,
1417 and the importing module must define a function type called
1418 <symname>_func. The importer then adds
1419 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
1420 that wishes to call out to the exported functions. Care must be
1421 taken that <symname> is non-NULL in the importing module incase
1422 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
1423 definition was in the importers source. Study
1424 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
1425 m4_module_import will attempt to automatically load a module
1426 required for symbol access if it is not loaded already.
1428 * TODO: Removed the items fixed in this delta.
1429 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
1431 * m4/ltdl.h (lt_dlhandle_find): Declare it.
1432 * m4/module.c (m4_module_unload): Use it.
1433 * src/freeze.c (reload_frozen_state): Ditto.
1434 * m4/m4module.h (m4_export): Deleted. Removed all references.
1435 (M4_MODULE_IMPORT): New user convenience macro for importing
1436 arbitrary symbols from other modules.
1437 * m4/module.c (m4_module_import): New function to service
1438 M4_MODULE_IMPORT macro.
1439 (module_data): Removed. Looking up the tables on demand with
1440 lt_dlsym, rather than caching their addresses here simplifies the
1442 (m4_get_module_builtin_table, m4_get_module_macro_table):
1443 Removed. Changed all callers.
1444 (set_module_macro_table, set_module_builtin_table): Renamed to
1445 install_macro_table and install_builtin_table respectively, and
1446 simplified now that the cache is no more.
1447 * modules/gnu.c (builtin_symbols): Use this new mechanism to
1448 import m4_dump_symbols from the m4 module.
1449 (builtin_esyscmd): Likewise for m4_set_sysval and
1451 * modules/m4.c (m4_export_table): Removed. Functions are
1452 addressed with the new mechanism which doesn't need this.
1453 (m4_set_sysval): New exported accessor function to prevent
1454 problems with variable access on inferior architectures.
1455 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
1456 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
1457 that we can have some type safety.
1458 * modules/modtest.c (export_test): C level exported function for
1459 testing the new import mechanism.
1460 * modules/import.c: New file for the import end of the test.
1461 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
1462 * tests/modules.at: New test cases for intermodule symbol
1465 2003-08-07 Gary V. Vaughan <gary@gnu.org>
1467 * m4/m4module.c (m4_string): Moved from here...
1468 * m4/m4private.c (m4_string): ...to here.
1470 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
1472 2003-07-29 Gary V. Vaughan <gary@gnu.org>
1474 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
1475 already available to module writers through
1476 m4_{get,set}_nesting_limit_opt(), so moved from here...
1477 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
1478 (m4_create): Use it.
1480 2003-07-28 Gary V. Vaughan <gary@gnu.org>
1482 Aside from auditing path.c for m4module.h api obfuscation, this
1483 delta introduces the concept of private struct members in opaque
1484 data types to GNU m4: See the STYLE file for details.
1486 * TODO: Remind ourselves that a rewrite of path.c is needed.
1487 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
1489 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
1490 here and renamed. These type definitions are for internal api use
1491 only. Changed all callers.
1492 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
1494 * m4/path.c (search_path_env_init, search_path_add): ...to here
1495 and renamed. These calls were never used outside this file.
1496 Changed all callers.
1497 (dirpath): Moved functionality of this static declaration...
1498 * m4/m4private.h (struct m4): ...to this new internal only
1499 search_path field. Changed all callers.
1500 (m4__get_search_path): Added new internal api accessor.
1501 * m4/path.c (m4_search_path_info_new): Removed. Not used.
1502 (m4_include_init): Removed...
1503 * m4/m4.c (m4_create): ...because the new m4 field is now
1505 (m4_delete): Recycle search_path memory.
1506 * src/main.c (main): Don't call m4_include_init now that it's
1508 * doc/STYLE: Document convention for private fields in opaque
1511 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1513 Sometimes exporting the address of a symbol from a module isn't
1514 enough for other modules to call that symbol correctly. If
1515 custom data types are used for function parameters, they need to
1516 be known to the caller. This change introduces the concept of
1517 $(prefix)/include/modules/$(modulename).h to declare those
1518 structures. Also we move m4_dump_symbols from libm4 to the m4
1519 module to show this concept in action.
1521 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
1522 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
1523 exporting data structures from modules/m4.c.
1524 * modules/m4.c, modules/gnu.c: Include it.
1525 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
1526 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
1528 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
1530 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
1531 ...to here, with slight renaming.
1532 (m4_export_table): Prototype and add m4_dump_symbols.
1533 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
1534 definition of m4_dump_symbols.
1535 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
1536 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
1538 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1540 Create an export table in modules/m4.c in readiness for beefing up
1541 the module loader to track module exports and imports.
1543 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
1544 * m4/debug.c (m4_debug_flush_files): Moved...
1545 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
1546 * modules/gnu.c (builtin_esysval): Use it.
1547 * m4/m4module.h (m4_export): New type for declaring module symbols
1549 * modules/m4.c (m4_export_table): List symbols exported from this
1550 module for use by other modules.
1552 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1554 An experiment: There is loads of code in libm4 which should be in
1555 the m4 module, but is also used by another module. Just because
1556 some linkers won't cope with calls across dynamic runtime loaded
1557 objects I initially left the code in libm4. It will tidy the
1558 module api immensely if this code moves to the right place, I just
1559 need to remember to invent a suitable calling mechanism at some
1560 point. For now, only modules that are statically linked and
1561 preloaded will get this treatment, so the only platforms that will
1562 break are those that require all symbols to be resolved at link
1565 * TODO: Reminder that what I am doing could reduce portability
1566 unless I do something more robust later.
1567 * m4/m4module.h (m4_sysval): No longer exported from libm4.
1568 * m4/utility.c (m4_sysval): No longer declared in libm4.
1569 * modules/Makefile.am: Reformatting.
1570 * modules/m4.c (m4_sysval): Declare it at place of use.
1571 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
1573 2003-07-23 Gary V. Vaughan <gary@gnu.org>
1575 * m4/m4module.h: Reformatting and rearranging lines a bit.
1576 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
1578 (m4_call_macro, m4_expand_input): Renamed...
1579 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
1581 (m4_expansion_level, m4_process_macro): Moved...
1582 * m4/macro.c (expansion_level, process_macro): ...to here, and
1585 * m4/m4module.h (program_name): Not used by modules at all, so
1587 * src/main.c (program_name): ...to here.
1588 (print_program_name): Renamed...
1589 (print_program_name_CB): ...to conform to the STYLE guide.
1591 2003-07-23 Gary V. Vaughan <gary@gnu.org>
1593 More refactoring of the m4module.h API. Replace #defines with an
1594 enum, and move non-public functions out of the public API.
1596 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
1598 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
1599 * m4/debug.c (m4_debug, trace): Moved...
1600 * m4/m4private.h (struct m4): ...to fields of this struct.
1601 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
1603 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
1604 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
1605 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
1606 * m4/m4module.h (m4_context_field_table): Add entries for new
1607 debug_file and trace_messages fields.
1608 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
1609 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
1610 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
1611 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
1612 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
1613 (m4_is_debug_bit): New macro to simplfy checks against the debug
1615 (m4_trace_format, m4_trace_header, m4_trace_flush)
1616 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
1618 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
1619 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
1620 * m4/macro.c (trace_format, trace_header, trace_flush)
1621 (trace_prepre, trace_pre, trace_post): ...to these newly static
1622 functions, since they are only ever used from this file. Changed
1625 2003-07-17 Gary V. Vaughan <gary@gnu.org>
1627 Change the macros for checking syntax so that matching against
1628 multiple possible syntax classes can be done with a single
1629 comparison some of the time. The various classes are now bits of
1630 an int that can be checked with bitwise logic operators.
1632 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
1633 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
1634 (M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)
1635 (M4_SYNTAX_ASSIGN, M4_SYNTAX_ALPHA, M4_SYNTAX_NUM)
1636 (M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)
1637 (M4_SYNTAX_ECOMM): Replaced #defines with an enum.
1638 (M4_SYNTAX_ALNUM): Removed. Changed all callers.
1639 (M4_IS_IGNORE, M4_IS_OTHER, M4_IS_SPACE, M4_IS_OPEN, M4_IS_CLOSE)
1640 (M4_IS_COMMA, M4_IS_DOLLAR, M4_IS_ACTIVE, M4_IS_ESCAPE)
1641 (M4_IS_ASSIGN, M4_IS_ALPHA, M4_IS_NUM, M4_IS_LQUOTE, M4_IS_RQUOTE)
1642 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
1643 Replace all calls with invocations of these...
1644 (m4_is_syntax, m4_has_syntax): ...New macros.
1645 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
1646 is no longer required with new macros. Changed all callers.
1648 2003-07-15 Gary V. Vaughan <gary@gnu.org>
1650 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
1651 values are returned as part of the internal interface, so they
1653 * m4/private.h: ...to here.
1654 * m4/macro.c (expand_token): Check for out of range
1655 m4_peek_input() results before looking up in the syntax table.
1656 (collect_arguments): Ditto.
1658 * NEWS: Note `$' syntax class.
1660 2003-07-08 Paul Eggert <eggert@twinsun.com> and
1661 Gary V. Vaughan <gary@gnu.org>
1663 Conform to POSIX if the POSIXLY_CORRECT environment is set.
1664 --traditional `define' now smashes all the definitions.
1666 * NEWS: Explain this.
1667 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
1668 (Extensions): Explain that extensions that are incompatible with
1669 POSIX are disabled if POSIXLY_CORRECT is set.
1670 (Incompatibilities): Remove.
1671 (Define, Other Incompat): Explain difference
1672 between GNU and POSIX behavior of define, pushdef, popdef.
1673 * m4/m4.c (m4_get_posixly_correct_opt): New undef.
1674 * m4/m4module.h (m4_context_opt_bit_table): Add POSIXLY_CORRECT entry.
1675 * m4/m4private.h (M4_OPT_POSIXLY_CORRECT_BIT): New macro.
1676 (m4_get_posixly_correct_opt): New macro.
1677 * m4/m4macro.c (m4_process_macro): Disable $10, $abc etc. if
1679 * modules/m4.c (builtin_functions): defn now takes any number of args.
1680 (builtin_define): Smash all the definitions if
1682 (builtin_defn)): Allow any number of arguments.
1683 (builtin_undivert): Do not allow nonnumeric arguments
1685 * src/main.c (main): Set posixly-correct behavior if either
1686 POSIXLY_CORRECT is set, or if -G is given.
1687 * tests/builtins.at: New test for smashed definitions.
1689 2003-06-27 Gary V. Vaughan <gary@gnu.org>
1691 * doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
1692 * m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
1693 not to slow the parser down.
1694 (M4__IS_STRING): New macro to test string syntax class membership.
1695 * m4/syntax.c: Adjust docucomment.
1696 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
1697 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
1698 * m4/input.c (init_builtin_token): Comment typo.
1699 (m4__next_token): Comment typo.
1700 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
1701 by using the new M4__IS_STRING macro.
1702 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
1703 variable references in macro expansions.
1705 * doc/m4.texinfo (Eregexp and Regexp): Typo.
1706 (Epatsubst and Patsubst): Typo.
1709 2003-06-26 Gary V. Vaughan <gary@gnu.org>
1711 Move the global variables that pertain to syntax to a new `struct
1712 m4_syntax_table', and then add one of these to `struct m4'. The
1713 ripple effect through the code to both change formerly global
1714 references, and make sure a suitable context is available in
1715 lexical scope is disproportionately large compared to the size of
1716 the change proper. This change is a large part of decoupling
1717 syntax.c from the rest of the code that uses it.
1719 * m4/m4private.h (struct m4): Add a syntax field.
1720 * m4/m4.c (m4_create): Initialise it,
1721 (m4_delete): Recycle it.
1722 (m4_get_symtab): Remove hand coded version...
1723 (m4_get_symbol_table): ...and generate this with cpp. Changed all
1725 * m4/m4module.h (m4_context_field_table): Add an extra field so we
1726 can generate m4_get_symbol_table. Add a new row for
1727 m4_get_syntax_table.
1728 (M4SYNTAX): Syntactic sugar for module writers.
1729 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
1730 (m4_syntax_table): New home for syntax related formerly global
1732 * m4/m4private.h (struct m4_syntax_table): Define it.
1733 * m4/input.c (m4_input_init): Initialisation of these formerly
1734 global variables moved...
1735 * m4/syntax.c (m4_syntax_create): ...to here.
1736 * m4/input.c (m4_input_exit): And similarly, recycling of the
1737 memory used by those values moved...
1738 * m4/syntax.c (m4_syntax_delete): ...to here.
1739 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
1740 Moved to m4/m4private.h.
1741 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
1742 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
1743 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
1744 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
1745 objects. Changed all callers that used to directly access the
1747 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
1748 Removed and incorporated into m4_syntax_table structure.
1749 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
1750 * m4/syntax.c (m4_set_syntax): Now returns an error status,
1751 instead of requiring a `struct m4' to generate its own errors.
1752 Changed all callers.
1753 * src/main.c (main): Now that the syntax table is initialised as
1754 part of m4_create, we have to manually wipe the syntax entries if
1755 we are about to read a frozen file.
1757 2003-06-26 Gary V. Vaughan <gary@gnu.org>
1759 * doc/STYLE: Added notes on callback naming schemes.
1761 * m4/module.c (m4_set_module_macro_table)
1762 (m4_set_module_builtin_table): Declarations weren't changed when
1763 definitions were renamed on 2003-06-19.
1765 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
1766 neither used nor particularly appropriate since it exposes the
1767 internal workings of the hash module. I haven't yet decided
1768 whether to remove it entirely.
1770 2003-06-20 Gary V. Vaughan <gary@gnu.org>
1772 Two related changes, and a huge knockon effect throughout the
1773 source: Moved the option variables out of global space and into
1774 `struct m4'; made `m4_symtab' a real datatype, so that its api
1775 is not marred passing `struct m4' around just so it can decide
1776 whether to keep traced symbol names or not. Added setters and
1777 getters for the formerly global option variables, and obviously
1778 changed a vast number of functions to take a `struct m4' and use
1779 the getter funcs to find option values.
1781 * m4/utility.c (interactive, sync_output, debug_level)
1782 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
1783 (max_debug_argument_length, warning_status, nesting_limit)
1784 (discard_comments): Removed.
1785 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
1786 (debug_level, max_debug_argument_length, prefix_all_builtins)
1787 (suppress_warnings, discard_comments, interactive, sync_output):
1788 Removed from here...
1789 * m4/m4private.h (struct m4): ...and equivalent fields added to
1791 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
1792 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)

1794 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
1795 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
1796 macros for the new fields.
1797 * m4/m4module.h (m4_context_field_table)
1798 (m4_context_opt_bit_table): Helper macros used to generate
1799 prototypes, setters and getters for new option fields
1801 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
1802 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
1803 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)

1809 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
1810 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
1811 setter and getter functions generated by cpp from
1812 m4_context_field_table and m4_context_opt_bit_table, exported as
1813 part of the module api. Changed all callers.
1814 * m4/symtab (struct m4_symtab): Used as the concrete type for
1816 (m4_symtab_create): Allocate and initialise a new struct.
1817 (m4_symtab_apply): New function that works like m4_hash_apply, but
1818 with different callbacks specific to symbol tables. Changed all
1820 (symbol_destroy, arg_destroy, arg_copy): Renamed
1821 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
1822 they have unused parameters for a reason!
1823 (dump_symbol_CB): New callback to dump the contents of a single
1825 (symtob_dump): Rewritten in terms of dump_symbol_CB.
1826 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
1827 Changed all callers.
1828 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
1829 of the contained `m4_symtab' at the `no_gnu_extensions' field.
1830 Although I'm not convinced these semantics are correct, they are
1831 at least consistent with how things were before this delta. Also
1832 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
1834 2003-06-19 Gary V. Vaughan <gary@gnu.org>
1836 Tie down the interface to libm4 some more. Make more structures
1837 opaque to modules by moving them to m4private.h, and writing
1838 setters and getters. To win back the speed penalty for doing this
1839 also wrote macroized versions that do know about structure layout
1840 in m4private.h and #include that file into modules when NDEBUG is
1841 defined at compile time. There are still some accessor macros in
1842 m4private.h that need to go, but that is not necessary to clean
1845 * m4/m4module.h (m4_symbol_type): Moved...
1846 * m4/m4private.h (m4__symbol_type): ...to here.
1847 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
1848 (m4_set_symbol_traced, m4_set_symbol_name_traced)
1849 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
1850 (m4_get_symbol_func, m4_symbol_value_create)
1851 (m4_symbol_value_delete, m4_set_symbol_value_text)
1852 (m4_set_symbol_value_func): New exported api to symbols.
1853 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
1854 and m4_is_symbol_value_func.
1855 * m4/m4module.h: Prototype these guys.
1856 * m4/module.c (m4_set_module_macro_table)
1857 (m4_set_module_builtin_table): Make these static, there is no
1858 reason to pollute the api with them.
1859 * m4/m4private.h: Reformatting.
1860 (m4_get_symtab): Only define when NDEBUG is defined.
1861 (m4_get_symbol_value, m4_get_symbol_traced)
1862 (m4_set_symbol_traced, m4_set_symbol_name_traced)
1863 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
1864 (m4_get_symbol_func, m4_symbol_value_create)
1865 (m4_symbol_value_delete, m4_set_symbol_value_text)
1866 (m4_set_symbol_value_func): Macro implementations of the new
1867 functions when NDEBUG is defined.
1868 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
1869 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
1870 Superceded by the above. All callers changed.
1871 (M4ARG): Removed. This is no longer different to the
1872 m4/m4module.h definition.
1873 * modules/gnu.c, modules/m4.c: Only include m4private.h when
1874 NDEBUG is defined. That way we exercise the same (albeit slower)
1875 api that external modules must use.
1877 2003-06-18 Gary V. Vaughan <gary@gnu.org>
1879 Renamed some of the types and their accessors to make more sense.
1880 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
1881 has a stack of SYMBOL_VALUEs.
1883 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
1884 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
1885 m4_get_symbol_value_type, m4_get_symbol_value_text,
1886 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
1887 Changed all callers.
1888 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
1889 (m4_get_token_type): Renamed
1890 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
1891 to the internal api.
1892 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
1894 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
1895 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
1896 (m4__token_type): Moved here from m4module.h.
1897 (m4__next_token): Renamed from m4_next_token.
1898 * m4/symtab.c: Removed some of the parameterised macro support
1899 functions for modularisation later.
1900 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
1901 m4_hash_dup to perform a true deep copy of the SRC.
1902 (arg_copy): Callback for m4_symbol_value_copy.
1903 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
1904 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
1905 m4_get_symbol_value_func. Changed all callers.
1907 2003-06-18 Gary V. Vaughan <gary@gnu.org>
1909 Tidy up style of hash.[ch] in accordance with doc/STYLE.
1911 * m4/hash.c: Internal symbol renaming and formatting.
1912 (m4_hash_dup): New function to facilitate deep copies of hash
1914 (m4_hash_apply_func): Returns a void* now, which is a richer type
1915 for returning exceptions (NULL means keep going).
1916 (m4_hash_apply): Ditto.
1917 * m4/hash.h: Declare exported symbols with an explicit extern.
1920 2003-06-17 Gary V. Vaughan <gary@gnu.org>
1922 Still refactoring furiously. This delta represents a change in
1923 semantics to symtab.c. Instead of building temporary m4_tokens
1924 in the caller, and copying fields in the methods, we now create
1925 the actual m4_token for hashing in the caller so the methods just
1926 slot them in directly. Also, this means that we don't lookup a
1927 symbol and get back an allocated but VOID token to copy fields
1928 into, we create the token we want to push and pass that to
1929 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
1930 a few other small changes to stop knowledge of the implementation
1931 of symtab.c leaking out into other files.
1933 * m4/macro.c (expand_argument): Comment typo corrected.
1934 * m4/symtab.c (symtab_fetch): New function to fetch the address of
1936 (m4_symbol_pushdef): Take an extra value parameter and use this
1937 directly as the new top of the value stack. All callers changed
1938 to build a token and pass responsibility for memory in, rather
1939 than copying as we used to.
1940 (m4_symbol_define): Also use the new value parameter directly as a
1941 replacement for the top of the value stack. All callers changed
1942 to build a token as above.
1943 (m4_set_symbol_traced): New function to set the traced bit on the
1944 named symbol, creating it if necessary.
1945 (symbol_popval): The guts of the old m4_symbol_popdef.
1946 (m4_symbol_popdef): Use it.
1947 * m4/builtin.c (m4_symbol_set_token): Removed,
1948 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
1950 * m4/module.c (m4_set_module_builtin_table)
1951 (m4_set_module_macro_table): ...with these more orthogonal
1953 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
1954 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
1956 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
1957 (m4_arg_signature_parse): Moved...
1958 * m4/symtab.c: ...to here.
1959 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
1960 screw something up. Moved...
1961 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
1962 actually does a proper deep copy of source to dest.
1964 2003-06-16 Gary V. Vaughan <gary@gnu.org>
1966 Further refactoring to stabilise the module API. Renaming some
1967 functions for orthogonality, and judicious definition migration to
1968 move things out of the set of exported symbols.
1970 * doc/STYLE: New file. Notes on coding style.
1971 * m4/m4module.c: Updated bitrotted docucomment at the top of the
1973 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
1974 m4_get_module_name, m4_get_module_builtin_table,
1975 m4_get_module_macro_table which are verb phrases. Changed all
1977 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
1979 * m4/module.c (m4_set_module_builtin_table)
1980 (m4_set_module_macro_table): ...here, and renamed. Changed all
1982 * m4/m4module.c (m4_module_data): This...
1983 * m4/m4private.c (struct m4_module_data): ...and this...
1984 * m4/module.c (module_data) ...consolidated here and no longer
1985 exported. Changed all callers.
1987 2003-06-16 Gary V. Vaughan <gary@gnu.org>
1989 Begin work on lifting the curse of the global variables. To start
1990 with create a `struct m4' context container, and replace
1991 `m4__symtab' with `context->symtab' throughout. This means
1992 initialising a context container in main, and adjusting many
1993 functions between main and the module entry points so that the
1994 container gets passed through. It would have been nice to
1995 defer this until after 1.5, but it has a major effect on the
1996 user's module writing ABI, so it needs to be addressed now - at
1997 least in the areas that impact the ABI. An interrelated change
1998 in the symtab API removes the dependency on a global symbol table,
1999 and instead focuses on a passed table (from the context
2002 * TODO: Reminders for finishing context functionality.
2003 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
2004 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
2005 global variables and eventually allow m4 to be reentrant.
2006 * m4/m4private.h (m4): Define the new structure here...
2007 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
2008 don't carry the overhead of a function call.
2009 * m4/m4module.h: Prototype extern functions from m4/m4.c.
2010 (m4): Declare type for new struct m4 objects.
2011 (M4SYMTAB): User macro to ease finding the symbol table for the
2012 current context for module developers.
2013 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
2015 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
2016 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
2017 (m4_call_macro, m4_dump_symbols, m4_expand_input)
2018 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
2019 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
2020 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
2021 m4* context parameter. Changed definitions and all callers.
2022 (m4_symtab): Alias for m4_hash to decouple the
2023 m4_symtab api from m4_hash.
2024 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
2026 (m4_symtab_create): New function to return an initialised
2028 (m4_symtab_delete): New function to delete an m4_symtab's memory.
2029 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
2030 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
2031 instead of simply using the global m4__symtab. Changed
2032 definitions and all callers.
2033 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
2034 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
2035 * src/main.c (main): Create a context and use that instead of the
2036 former global m4__symtab.
2038 2003-06-13 Gary V. Vaughan <gary@gnu.org>
2040 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
2041 to the callback. Callbacks should not need to hardcode the
2042 hashtable they are working from, nor should we have to waste the
2043 userdata parameter to pass the table in.
2044 * m4/hash.h (m4_hash_apply_func): Require the initial table
2046 * m4/symtab.c (symtab_destroy): Use the passed table instead
2047 of hardcoding m4__symtab.
2048 (m4_symbol_popdef): Don't use the userdata parameter to pass the
2049 table to arg_destroy.
2050 (arg_destroy): Use the hash parameter, ignore userdata.
2051 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
2053 (traceon, traceoff): Call set_trace with the extra initial
2056 2003-06-13 Gary V. Vaughan <gary@gnu.org>
2058 More refactoring to stabilise the module api, this time for
2059 symtab.c. Additionally, start to pay attention to function names
2060 that don't contain a verb like they should.
2062 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
2063 wrapper for m4_hash_apply to decouple the symtab module from the
2065 (m4_symbol_builtin, m4_symbol_macro): Renamed to
2066 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
2068 (m4_symbol_delete): Create a macro version to save a function
2070 (m4_token_t, m4_data_t): These violate the POSIX reserved
2071 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
2073 (m4_token_type): Renamed to m4_token_get_type.
2074 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
2075 (m4_symtab_exit): Removed from the exported module
2077 * m4/m4private.h (m4__symtab, m4__symtab_init)
2078 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
2079 renamed and added to the internal api. Changed all callers.
2080 (m4_symtab_apply): A faster macro version of the function for
2081 users of the internal api.
2082 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
2083 symbol_destroy and arg_destroy.
2084 (symtab_debug): Added a prototype.
2085 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
2086 so that callers in this file get the faster macro versions from
2089 2003-06-12 Gary V. Vaughan <gary@gnu.org>
2091 Refactoring modules to rationalise the API into an external
2092 documented (eventually!) API for use by modules in the `m4_'
2093 namespace declared in m4/m4module.h, an internal API between the
2094 source files we ship (including our shipped modules) in the `m4__'
2095 namespace declared in m4/m4private.h and making the rest as
2096 cohesive as possible with liberal use of the `static' keyword.
2097 This change represents an audit to m4/module.c along these
2100 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
2101 Removed. No longer used.
2102 (m4_module_close): Removed prototypes.
2103 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
2104 from the exported module api...
2105 * m4/m4private.h (m4__module_init, m4__module_open)
2106 (m4__module_exit): ...and renamed and added to the internal api.
2107 Changed all callers.
2108 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
2109 Centralised definitions after renaming...
2110 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
2111 (M4_FINISH_SYMBOL): ...and removing from here.
2112 (m4_module_dlerror, m4_module_remove, m4_module_close)
2113 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
2114 module_remove, module_close and caller_id.
2115 (MODULE_SELF_NAME): New macro to make reporting self errors
2117 (m4_module_load, module_close, module_remove): Use it.
2118 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
2120 * src/main.c (main): Use it.
2122 2003-06-12 Gary V. Vaughan <gary@gnu.org>
2124 * README: Remove references to --enable-changeword, which has been
2125 removed from the code.
2127 2003-06-11 Gary V. Vaughan <gary@gnu.org>
2129 Getting rid of the annoying bug with configure --enable-debug,
2130 which spewed -e: command not found errors. This was an interaction
2131 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
2132 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
2133 branch-1-5) to get the full fix.
2135 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
2136 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
2137 and then use the probed value of $SED.
2138 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
2139 this, it messes up the AC_REQUIRE stack.
2141 2003-06-10 Gary V. Vaughan <gary@gnu.org>
2143 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
2144 the destroy callback.
2145 (m4_arg_destroy): Use the hash address to free the hash node key
2148 2003-06-06 Gary V. Vaughan <gary@gnu.org>
2150 First cut at formal parameters in macros.
2152 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
2153 * m4/xstrzdup.c: New file.
2154 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
2155 associative array of parameter names to details.
2156 (m4_symbol_token): Capture macro names with parameter lists.
2157 (m4_arg_signature_parse): And build an associative array to hang
2158 from the symbol structure to map names to details.
2159 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
2160 m4_hash_resize idiom. Now that we potentially add a little hash
2161 table to many of the entries in the symbol table, added an extra
2162 arg to set the initial size. Changed all callers.
2163 (m4_hash_apply): New function that is basically a generalised
2165 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
2166 all callers to call m4_hash_apply instead.
2167 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
2168 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
2169 m4_arg_signature association that might be attached to the symbol,
2170 * m4/hash.h (m4_hash_apply_func): Replacement type for...
2171 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
2172 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
2174 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
2175 (M4_IS_IDENT): Detect characters that can be safely used in
2177 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
2178 * m4/macro.c: Corrected grammar in some comments. Use `token'
2179 rather than `td' for m4_token variables.
2180 (m4_process_macro): If we find a dollar followed by some
2181 M4_IS_IDENT characters, replace that with the contents of the argv
2182 entry with offset stored in the m4_token_arg associated with the
2183 collected identifier.
2185 2003-06-05 Gary V. Vaughan <gary@gnu.org>
2187 Begin preparations for supporting formal parameters in m4 macros.
2189 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
2190 the details of a formal parameter.
2191 (m4_token): Add an arg_signature member to hold a hash table for
2192 looking up formal parameters.
2193 * m4/input.c: Update more bitrotted comments.
2194 (m4_push_builtin): Initialise arg_signature member.
2195 (init_builtin_token): Copy arg_signature member.
2196 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
2197 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
2199 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
2200 (m4_macro_pushdef, m4_macro_define): ...these, And...
2201 (m4_symbol_token): ...wrapped around this new function, which
2202 vastly simplifies the arguments required by the functions it
2204 Changed all callers.
2206 2003-06-05 Gary V. Vaughan <gary@gnu.org>
2208 * m4/macro.c: Format changes.
2210 2003-06-04 Gary V. Vaughan <gary@gnu.org>
2212 * m4/input.c: Updated various bitrotted comments.
2213 (m4_push_builtin): Just pass the whole m4_token, rather than
2214 extracting all the fields in the caller. This also allows us to
2215 check the token type for consistency.
2216 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
2217 Renamed to builtin_funcs, builtin_peek, builtin_read,
2218 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
2219 the code. Changed all callers.
2220 (struct input_block): Similarly renamed u_m member to u_b, and
2221 changed all callers.
2222 (m4_next_token): Use bzero to initialise the data fields.
2223 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
2225 2003-05-29 Gary V. Vaughan <gary@gnu.org>
2227 These changes were necessary to get m4 to build on my iBook
2228 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
2229 (GCC) 3.1 20020420 (prerelease)":
2231 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
2232 inclusion of module loader headers.
2233 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
2234 * m4/Makefile.am: Ditto.
2235 (libm4_la_LIBADD): Added $(LTLIBINTL).
2236 * m4/utility.c (program_name): Removed declaration in favour of
2237 the one already in error.c!
2238 * m4/m4module.h (program_name): Define to program_invocation_name
2239 when using GNU C library. Use an explicit extern declaration.
2240 (interactive, sync_output, debug_level, hash_table_size)
2241 (no_gnu_extensions, prefix_all_builtins, max_debug_argument_length)
2242 (suppress_warnings, warning_status, nesting_limit, discard_comments)
2243 (lquote, rquote, bcomm, ecomm, m4_bad_argc, m4_skip_space)
2244 (m4_numeric_arg, m4_shipout_int, m4_shipout_string, m4_dump_args)
2245 (m4_debug, m4_debug_init, m4_debug_exit, m4_debug_decode)
2246 (m4_debug_flush_files, m4_debug_set_output, m4_debug_message_prefix)
2247 (m4_trace_prepre, m4_trace_pre, m4_trace_post, m4_sysval)
2248 (m4_expansion_level, m4_expand_ranges, m4_expand_input)
2249 (m4_call_macro, m4_process_macro, m4_syntax_table, m4_current_file)
2250 (m4_current_line, m4_current_diversion, m4_output_current_line):
2251 Don't rely on default, use an explicit extern.
2252 * m4/error.h (error, error_at_line, error_print_progname)
2253 (error_message_count, error_one_per_line): Ditto.
2254 * m4/ltdl.c: Update from CVS libtool.
2256 * commit: Update from CVS cvs-utils.
2258 2002-11-04 Akim Demaille <akim@epita.fr>
2260 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
2262 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
2264 2002-11-04 Akim Demaille <akim@epita.fr>
2266 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
2268 2002-11-04 Akim Demaille <akim@epita.fr>
2270 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
2271 used as `external', and Libtool 1.4.3.
2273 (LTLIBOBJS): Don't play with it.
2275 * Makefile.am (SUBDIRS): Remove intl.
2276 (ACLOCAL_AMFLAGS): Add -I config.
2277 (EXTRA_DIST): Add config/config.rpath.
2280 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
2282 2002-05-29 Gary V. Vaughan <gary@gnu.org>
2284 Preparations for refactoring syntax tables to allow reverse
2285 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
2286 speed of normal lookups in an array of unsigned short.
2288 * m4/input.c (single_quotes, single_comments, use_macro_escape):
2290 * m4/m4private.h (m4__single_quotes, m4__single_comments,
2291 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
2292 is for internal symbols which unavoidably pollute the global
2293 namespace, but are not published APIs.
2294 Adjusted all callers.
2295 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
2296 m4_set_comment, m4_set_syntax, set_syntax_internal,
2297 unset_syntax_attribute): Moved from this file...
2298 * m4/syntax.c: New. ...to this file.
2299 Also added an m4_syntax_exit stub for orthogonality.
2300 * src/main.c (main): Use it.
2301 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
2302 * m4/m4module.h: Reformatting. New prototypes.
2304 2002-05-29 Gary V. Vaughan <gary@gnu.org>
2306 * bootstrap (aclocal_apiversion): The aclocal apiversion is
2307 distinct from the automake release number (in that the apiversion
2308 apparently has no micro-version-component).
2309 (aclocal_apilibdir): Use it.
2311 2002-05-28 Gary V. Vaughan <gary@gnu.org>
2313 * m4/hash.c (m4_hash_resize): New function.
2314 * m4/hash.h: Add prototype.
2315 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
2316 benchmarking to find a good value for, say, autoconf. This is
2317 already a little quicker than before for me.
2319 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
2320 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
2322 * m4/hash.h: Adjust prototypes.
2324 2002-01-22 Akim Demaille <akim@epita.fr>
2326 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
2328 * tests/Makefile.am (package.m4): New.
2329 * tests/atlocal.in: Adjust to CVS Autotest.
2330 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
2331 * configure.ac: LIBOBJ is a forbidden string.
2332 Simplify AM_INIT_AUTOMAKE invocation.
2333 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
2336 2001-10-19 Akim Demaille <akim@epita.fr>
2338 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
2340 2001-10-19 Akim Demaille <akim@epita.fr>
2342 * m4/input.c (m4_next_token): Display where was opened what is
2345 2001-10-19 Akim Demaille <akim@epita.fr>
2347 * m4/macro.c (expand_argument): Display where was opened what is
2350 2001-10-18 Akim Demaille <akim@epita.fr>
2352 * m4/input.c, modules/m4.c: Formatting changes.
2354 2001-10-17 Gary V. Vaughan <gary@gnu.org>
2356 * bootstrap: s/configure.in/configure.ac/
2358 2001-10-16 Gary V. Vaughan <gary@gnu.org>
2360 * m4/symtab.c (m4_symbol_destroy): This function calls
2361 m4_symbol_popdef, which recycles a symbols memory when the last
2362 definition is popped. Since we were passing the address of the
2363 symbol name found in the symbol table, and it was being removed
2364 partway through m4_symbol_destroy() we were referencing freed
2365 memory for the balance of the function. Now we take a copy of the
2366 symbol name tring and use that as a key into the symbol
2367 table... that way if the original symbol name is freed, the copy
2370 2001-10-13 Akim Demaille <akim@epita.fr>
2372 * m4/ltdl.c: Update.
2374 2001-10-13 Akim Demaille <akim@epita.fr>
2376 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
2377 Don't gettextize internal error messages.
2379 2001-10-13 Akim Demaille <akim@epita.fr>
2381 * tests/macros.at (Arity and defn): New failing test.
2382 (Arity, defn, and freeze): New.
2384 Fix `Arity and defn'.
2386 * m4/input.c (m4_push_macro): Don't forget the arity.
2387 * modules/m4.c (defn): Likewise.
2389 2001-10-13 Akim Demaille <akim@epita.fr>
2391 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
2393 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
2394 (Propagation of traceon, Propagation of --trace): this new file.
2396 2001-10-13 Akim Demaille <akim@epita.fr>
2398 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
2399 interface instead of (name, argc...).
2400 Upon failure, specify which argument was guilty.
2403 2001-10-13 Akim Demaille <akim@epita.fr>
2405 * modules/evalparse.c: Save translators' time: don't translate
2406 internal error messages.
2407 (m4_evaluate): Simplify/normalize error messages.
2408 * doc/m4.texinfo (Eval): Adjust.
2410 2001-10-13 Akim Demaille <akim@epita.fr>
2412 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
2413 where no checking is needed.
2414 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
2415 interface instead of (name, argc...).
2417 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
2420 2001-10-13 Akim Demaille <akim@epita.fr>
2422 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
2423 exclude the builtin name from the count.
2424 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
2425 calling ifelse with a single argument is valid.
2426 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
2427 with 1 and 2 args, mostly to strengthen the test suite.
2429 2001-10-13 Akim Demaille <akim@epita.fr>
2431 * m4/output.c (m4_make_diversion, m4_insert_file)
2432 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
2434 2001-10-12 Gary V. Vaughan <gary@gnu.org>
2436 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
2437 since we call these things builtins in the rest of the code!
2439 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
2441 2001-10-12 Gary V. Vaughan <gary@gnu.org>
2443 Rather than forcing each builtin definition to manage its own
2444 argument range checking, tabulate the maxima and minima for all
2445 builtins in each module. This forces us to consider what the
2446 valid ranges for each builtin should be, and moves the checking
2447 code out of each builtin implementation and into the builtin
2448 caller infrastructure.
2450 * m4/m4module.h (struct m4_builtin): Add argument minima and
2452 * m4/m4private.h (struct m4_token): Reflect them here too.
2453 * m4/input.c (struct input_block): ...and here.
2454 (m4_token_copy): New function for token copying.
2455 (init_macro_token): Copy them from a token to the input stack.
2456 (m4_next_token): Don't forget to initialise them for text
2458 * m4/macro.c (expand_argument): Use m4_token_copy, and also
2459 check argument counts before calling the builtin handler.
2460 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
2461 (m4_symbol_macro): Likewise.
2462 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
2463 parameters. Updated all callers.
2464 (m4_builtin_define): Ditto.
2465 (m4_macro_pushdef, m4_macro_define): Ditto.
2466 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
2467 * modules/evalparse.c: Declare argument counts for defined
2468 builtins and remove explicit calls to m4_bad_argc().
2469 * modules/gnu.c: Ditto.
2470 * modules/load.c: Ditto.
2471 * modules/m4.c: Ditto.
2472 * modules/modtest.c: Ditto.
2473 * modules/mpeval.c: Ditto.
2474 * modules/perl.c: Ditto.
2475 * modules/shadow.c: Ditto.
2476 * modules/stdlib.c: Ditto.
2477 * modules/time.c: Ditto.
2480 2001-10-10 Gary V. Vaughan <gary@gnu.org>
2482 The trace semantics now attach the trace bit to a symbol name.
2483 For as long as a traceon(`foo') is active, calls to foo will be
2484 traced regardless of intervening undefines or module unloads.
2485 Fixed the flag propogation issues differently to the fixes
2486 reverted with the last attempt at nailing down trace:
2488 * m4/m4private.h: This file is not visible outside of the m4
2489 source tree, so I removed all the `M4_' and `m4_' prefixes to save
2490 on typing. Updated all clients.
2491 (m4_token): New typedef contains the fields that need to be passed
2492 around with the low level tokeniser.
2493 (m4_token_data): Removed.
2494 (m4_symbol): Now contains the traced flag again.
2495 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
2496 the trace bit set. This change is contained entirely within this
2497 module and doesn't leak out into the callers. Updated all
2499 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
2500 new fields in m4_token. Updated all clients.
2501 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
2502 that `groks_macro_args' and `blind_if_no_args' flags are retained
2503 when defn() results are passed around in m4 code. Updated all
2505 (m4_builtin_define): Ditto.
2506 (m4_macro_pushdef, m4_macro_define): Ditto.
2507 * m4/input.c (struct input_block): Add a flags field to facilitate
2509 (m4_push_macro): ...use it.
2510 (init_macro_token): Retrieve it.
2511 (m4_next_token): Initialise it.
2512 * m4/macro.c (expand_argument): Copy it.
2513 * m4/m4module.h: Adjust.
2514 * tests/builtins.at: Adjust the expected output of the trace
2515 tests to reflect the change in semantics.
2516 * tests/modules.at (modules: trace): Check that unloading a
2517 module which supplies a traced symbol definition doesn't lose te
2520 2001-10-07 Gary V. Vaughan <gary@gnu.org>
2522 * modules/gnu.c (m4_macro_table): Display the timetamp when
2523 expanding __m4_version__.
2525 * configure.ac (--with-modules): Forgot a comma in the
2526 AC_HELP_STRING parameter list.
2528 2001-10-05 Gary V. Vaughan <gary@gnu.org>
2530 * bootstrap: Remove aclocal.m4t when it is no longer required.
2532 2001-10-05 Akim Demaille <akim@epita.fr>
2534 * tests/Makefile.am: Adjust for gnuprog2.
2535 * tests/m4.in: There can be a leading path.
2536 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
2537 * tests/testsuite.at: Adjust to the most recent Autotest.
2538 (AT_CHECK_M4_FILTER): Fix and rename as...
2540 * tests/others.at: Use it.
2542 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
2543 variable in shell scripts, one uses `$'...
2545 2001-10-04 Gary V. Vaughan <gary@gnu.org>
2547 * configure.ac: `rm -f $m4_getopt_h' was lost.
2549 2001-10-04 Gary V. Vaughan <gary@gnu.org>
2551 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
2552 time. Define it for config.h in order to...
2553 * src/main.c (main): ...display the timestamp for --version.
2555 2001-10-04 Akim Demaille <akim@epita.fr>
2557 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
2558 previous builtins `regexp' and `patsubst'.
2559 (regexp, patsubst): Use them.
2560 (eregexp, epatsubst): New builtins.
2561 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
2562 (Epatsubst and Patsubst, Eregexp and Regexp): these.
2563 (Extensions): More info on REs.
2565 2001-10-04 Akim Demaille <akim@epita.fr>
2567 * modules/modtest.c (init_handler): Consistently output to stderr.
2568 (finish_handler): New.
2569 (test): The `if' is an `assert'.
2570 * tests/modules.at: Adjust.
2572 2001-10-04 Akim Demaille <akim@epita.fr>
2574 * m4/utility.c (m4_bad_argc): Detail the mismatches.
2576 2001-10-01 Akim Demaille <akim@epita.fr>
2578 * tests/generate.awk: Tag the tests with `documentation'.
2579 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
2580 Use the make the existing modtest tests more uniform, and complete
2581 the set of possibilities.
2583 2001-10-01 Akim Demaille <akim@epita.fr>
2585 * config/gmp.m4: Consult the user before using GMP: use
2587 * configure.ac: Adjust.
2588 * modules/gmp.c: No protection needed as the module is not built
2591 2001-10-01 Akim Demaille <akim@epita.fr>
2593 * tests/generate.awk: Remove debugging code.
2594 (fatal): Specify the current location.
2596 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
2597 * modules/gnu.c, modules/m4.c: Use M4ARG.
2599 2001-10-01 Akim Demaille <akim@epita.fr>
2601 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
2602 (m4_regexp_compile): New.
2603 (regexp, patsubst): Use it.
2605 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2607 Reinstate the memory handling improvements from the patch I just
2608 reverted. Relevant ChangeLog entries repeated here:
2610 * m4/module.c (m4_module_remove): New function that holds the core
2611 of the old m4_module_unload.
2612 (m4_module_unload): Use it.
2613 (m4_module_unload_all): When we know the modules will never be
2614 used again (i.e. on exit), free up as much module memory as
2615 possible. There are still some artifacts from resident modules
2616 living inside ltdl.c, but everything else is freed.
2617 * m4/debug.c (m4_debug_exit): Free memory allocated in
2619 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
2620 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
2621 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
2622 * m4/m4module.h: Updated prototypes.
2623 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
2624 * m4/hash.h: Updated prototypes.
2625 * src/main.c (main): Use all these new functions to clean up as
2626 much memory as possible before exit.
2628 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2630 Reverted my large patch for removing the old m4_symbol
2631 structure on 2001-09-20. We are still not happy about the way
2632 trace works in conjunction with defn and undefine, and leaving
2633 the reverted patch active prevents us from moving the traced
2634 bit from the definition back to the symbol.
2636 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2638 * configure.in: Moved to...
2639 * configure.ac: ...here. Added a libtool like timestamped
2640 banner, and tidied up the libltdl cruft.
2641 * config/mkstamp: Script to extract a timestamp from ChangeLog.
2642 * modules/Makefile.am (INCLTDL): Removed. This is required
2643 only when libltdl is configured in a subdirectory.
2644 * src/Makefile.am: Ditto.
2645 (LIBADD_DL): No need to add this again, libtool already knows
2646 that libm4.la depends on it.
2647 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
2650 * TODO: stackovf.c is basically broken.
2651 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
2653 2001-09-28 Akim Demaille <akim@epita.fr>
2655 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
2657 2001-09-27 Akim Demaille <akim@epita.fr>
2659 * tests/m4.in: Don't use short options.
2660 Simplify the stderr signature normalization.
2662 2001-09-27 Akim Demaille <akim@epita.fr>
2664 tests/m4 shall be position independent.
2668 * tests/testsuite.at: No args to AT_INIT.
2669 * configure.in, tests/Makefile.am: Adjust.
2671 2001-09-22 Akim Demaille <akim@epita.fr>
2673 Autotest has changed again.
2675 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
2676 (package.m4): Remove.
2677 * configure.in: Adjust to LIBADD_GMP.
2679 2001-09-21 Gary V. Vaughan <gary@gnu.org>
2681 * config/gmp.m4 (AC_ARG_WITH): Removed.
2682 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
2683 (AC_LIB_GMP): When performing a test compile against libgmp,
2684 include the header gmp.h if possible, and link against -lgmp. If
2685 they both work define USE_GMP.
2686 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
2687 (mpeval_LTX_init_func): Complain on load that there was no libgmp
2690 2001-09-20 Gary V. Vaughan <gary@gnu.org>
2692 * m4/evalparse.c: Moved to...
2693 * modules/evalparse.c: ...here. This code is shared between
2694 modules/mpeval.c and modules/m4.c, so there is no need to pollute
2695 the libm4 API with its details. Moderately rewritten to interface
2696 into its clients more simply.
2697 * m4/eval.c: Deleted. Migrated functionality to...
2698 * modules/m4.c: ...here.
2699 (builtin_eval): Implemented in terms of the new interface style.
2700 * modules/mpeval.c (builtin_mpeval): Ditto.
2701 * m4/m4module.h: Removed references to the former m4/eval.c.
2702 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
2703 (EXTRA_libm4_la_SOURCES): Deleted.
2704 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
2705 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
2707 2001-09-20 Akim Demaille <akim@epita.fr>
2709 * config/gmp.m4 (AM_WITH_GMP): Rename as...
2711 By default, use gmp.
2713 * configure.in: Adjust.
2714 Use Automake conditionals for USE_GMP.
2715 Always compute sizeof (long long int).
2716 This was a bug BTW, as `eval' (not `mpeval') depends on it:
2717 before, it was used _only_ if mpeval was not activated.
2718 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
2719 (mpeval_la_LIBADD): New macros.
2720 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
2722 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
2723 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
2726 2001-09-20 Akim Demaille <akim@epita.fr>
2728 * tests/Makefile.am (package.m4): New.
2729 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
2731 2001-09-20 Gary V. Vaughan <gary@gnu.org>
2733 More cleanup. After the last patch, m4_symbol holds nothing but
2734 the head of a chain of m4_token_data. So I have removed the old
2735 m4_symbol, so that m4_token_data chains are stored directly in the
2736 value cell of a hash table node. But there's more... m4_symbol
2737 was a more natural name for the symbol value cell, and now that it
2738 is gone I have renamed the former m4_token_data structure to
2739 m4_symbol. This change turned out to be a pig to get right, since
2740 the original code didn't need to modify the value cell itself,
2741 since changing the chain happened inside the m4_symbol that used
2742 to be returned -- I had to pass the address of the value cell
2743 across various function calls, incase the head value changed. I
2744 also tightened up the memory management to help me find a nasty
2745 memory corruption bug that took me all night to track down...
2747 * m4/m4private.h (struct m4_symbol): Removed.
2748 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
2750 * m4/hash.c (m4_hash_iterator_value): Return the address of the
2751 value cell. Updated all callers.
2752 * m4/symtab.c: Took advantage of the simplification in the data
2753 structures to rewrite a lot of this file more simply. There is
2754 still some room for optimisation here, but we should tackle that
2755 systematically closer to the release.
2757 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
2758 revealed. This version is ahead of CVS libtool until I get chance
2759 to flush my changes.
2760 * m4/module.c (m4_module_remove): New function that holds the core
2761 of the old m4_module_unload.
2762 (m4_module_unload): Use it.
2763 (m4_module_unload_all): When we know the modules will never be
2764 used again (i.e. on exit), free up as much module memory as
2765 possible. There are still some artifacts from resident modules
2766 living inside ltdl.c, but everything else is freed.
2767 * m4/debug.c (m4_debug_exit): Free memory allocated in
2769 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
2770 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
2771 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
2772 * m4/m4module.h: Updated prototypes.
2773 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
2774 * m4/hash.h: Updated prototypes.
2775 * src/main.c (main): Use all these new functions to clean up as
2776 much memory as possible before exit.
2778 2001-09-18 Gary V. Vaughan <gary@gnu.org>
2780 The `traced' flag needs to be attached to the definition of a
2781 symbol rather than the current symbol containing the definition.
2782 Implementing this showed up some long standing post 1.4 bugs in
2783 flag propogation which I also fixed.
2785 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
2786 (struct m4_token_data): And add it back in here.
2787 * m4/input.c (init_macro_token): Propogate the traced flag
2789 * m4/macro.c (expand_argument): Ditto.
2790 * tests/builtins.at (trace2, trace3): New tests based on Akim's
2793 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2795 * m4/m4private.h (struct m4_token_data): Simplified by removing
2796 the redundant `traced' flag, and one level of structure nesting.
2797 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
2798 * m4/input.c (init_macro_token): No need to initialise removed
2800 * m4/macro.c (expand_argument): No need to copy it either.
2801 * m4/utility.c (m4_token_data_func_traced): Or provide an access
2804 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
2805 dependant on multiple symbols with the same key, so preserving
2806 relative symbol order in each bucket during resizing is no longer
2807 required. The resize function is considerably faster as a result.
2809 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
2810 s/m4_symbol_insert/m4_symbol_define/g;
2811 s/m4_builtin_insert/m4_builtin_define/g;
2812 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
2814 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2816 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
2817 commits, the m4_lookup_symbol dispatch function is split into
2818 specialised functions that must be called directly.
2820 * m4/m4module.h (m4_symbol_lookup_t): Removed.
2821 * m4/symtab.c (m4_lookup_symbol): Removed.
2822 (m4_symbol_builtin, m4_symbol_macro): New functions.
2823 * m4/builtin.c (m4_builtin_define): Split into...
2824 (m4_builtin_pushdef, m4_builtin_insert): ...these.
2825 (m4_macro_define): Split into...
2826 (m4_macro_pushdef, m4_macro_insert): ...these.
2827 * src/main.c (main): Set command line macros from `-D' parameters
2828 using `m4_macro_define'.
2830 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2832 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
2833 this from m4_remove_table_reference_symbols().
2834 * m4/m4module.h, m4/module.c: Updated all references.
2836 2001-09-07 Akim Demaille <akim@epita.fr>
2838 * modules/stdlib.c, modules/times.c: Misc cleanups.
2840 2001-09-07 Akim Demaille <akim@epita.fr>
2842 * configure.in: We now need Autoconf 2.52e.
2843 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
2844 and `M4_SYMBOL_DELETE'.
2845 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
2846 * src/main.c (main): Adjust.
2848 2001-09-06 Gary V. Vaughan <gary@gnu.org>
2850 Fix the obstack.h problem once and for all! At configure time we
2851 can test for a system supplied obstack.h: depending on the
2852 result, we now generate system.h with an #include of the correct
2853 header. As a bonus, I've also added a --with-included-obstack,
2854 incase the user doesn't like the system obstack for some
2855 reason... and also we can test the shipped obstack on a system
2856 that has oe of its own. We also now need to be careful to add
2857 build directories to the include search path, since the generated
2858 system.h will be in the build tree.
2860 * configure.in (AC_CONFIG_FILES): Generate system.h from
2862 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
2863 include the system obstack header or the copy shipped with M4.
2864 Allow the user to override configure and force the build to use
2865 the shipped version.
2866 * m4/system-h.in: New file, template for...
2867 * m4/system.h: ...this. Now deleted.
2868 * m4/m4module.h: Include system.h before everything else.
2869 * src/freeze.c: Ditto.
2870 * m4/Makefile.am (dist-hook): Remove generated system.h.
2871 (INCLUDES): Check builddir for generated headers before checking
2873 * modules/Makefile.am (INCLUDES): Ditto.
2874 * src/Makefile.am (INCLUDES): Ditto.
2876 2001-09-05 Gary V. Vaughan <gary@gnu.org>
2878 * TODO: Remove the items that have been addressed already.
2880 2001-09-05 Akim Demaille <akim@epita.fr>
2882 * src/main.c (main): Standardize --version.
2884 2001-09-05 Akim Demaille <akim@epita.fr>
2886 * modules/format.c (format): Have a bigger `str'.
2888 2001-09-05 Akim Demaille <akim@epita.fr>
2890 Rationalize warnings, reporting the macro name as if it were a
2891 program name, and assertions.
2893 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
2895 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
2897 Use assert for internal errors.
2898 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
2900 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
2902 * tests/builtins.at (pushpop): Adjust.
2904 2001-09-05 Akim Demaille <akim@epita.fr>
2906 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
2909 2001-09-05 Akim Demaille <akim@epita.fr>
2911 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
2912 * m4/macro.c, m4/symtab.c: Adjust.
2914 2001-09-05 Akim Demaille <akim@epita.fr>
2916 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
2917 (m4_symbol_pop, m4_symbol_del): this.
2918 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
2919 (m4_symbol_popdef, m4_symbol_delete): New.
2920 (m4_lookup_symbol): Adjust.
2921 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
2923 2001-09-05 Akim Demaille <akim@epita.fr>
2925 * m4/m4module.h (m4_symbol_lookup): Rename as...
2926 (m4_symbol_lookup_t): this.
2928 2001-09-05 Akim Demaille <akim@epita.fr>
2930 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
2932 * m4/symtab.c (m4_lookup_symbol): Adjust.
2934 2001-09-03 Gary V. Vaughan <gary@gnu.org>
2936 Bootstrap will now work with Libtool 1.4.1 or higher:
2937 * bootstrap: Remove stale autom4te.cache files when
2939 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
2941 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
2942 libtool.m4 directly.
2943 Run libtoolize to refresh ltmain.sh.
2944 * config/ltmain.sh: Deleted.
2945 * acinclude.m4: Deleted.
2946 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
2948 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
2949 implementation for the cvs impaired libtool user.
2951 2001-09-03 Akim Demaille <akim@epita.fr>
2953 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
2955 Avoid using `default' in switch, as it hides useful compiler
2956 warnings when a case is forgotten.
2958 2001-09-03 Akim Demaille <akim@epita.fr>
2960 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
2961 is no such thing as `WITH_MODULES'.
2963 2001-09-03 Akim Demaille <akim@epita.fr>
2965 Improve the test suite's selfcontainedness.
2967 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
2968 (Include, Undivert): Tag the other input files.
2969 * tests/generate.awk: Catch `@comment file:'.
2970 `-I $src' is no longer needed.
2971 `next' is really like `return': the rest is skipped.
2972 Adjust to `input.m4'.
2973 (fatal): New function.
2974 * tests/foo, tests/incl.m4: Remove.
2976 2001-09-01 Gary V. Vaughan <gary@gnu.org>
2978 The shadowing mechanism and, infact, the whole symbol table
2979 implementation was creaking under the weight of the features piled
2980 on top of it. We now have a separate hash table module which will
2981 dynamically resize to keep symbol density withing good performace
2982 limits, and a new symtab module layered above it. Symbol lookups
2983 are now marginally more efficient (since the shadowed flag is no
2984 longer required) and symbol removal, such as on module unload, is
2985 considerably faster due to a reorganisation of the data structures
2988 * src/main.c (main): Don't mention `-H'.
2989 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
2992 * m4/hash.c: New generalised dynamic hash table data structure
2994 * m4/hash.h: Public interface.
2995 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
2996 (libm4_la_SOURCES): Add hash.c.
2997 * m4/symtab.c: More or less rewritten from scratch, within the
2998 bounds of the previous API.
2999 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
3000 call. Updated all callers.
3001 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
3002 declarations to reflect API changes.
3003 (M4INIT): Generate a declaration too, to avoid the warning with
3004 --enable-debug builds.
3007 * m4/utility.c (hash_table_size): Removed.
3008 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
3009 names, which are then looked up by builtin_dumpdef() as necessary.
3010 This implies a small speedup in builtin_symbols(), which discarded
3011 all of the symbol info under the old call.
3012 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
3013 shadowing is implicit in respect to the new data structures.
3014 symbol names are no longer duplicated here, they are stored in the
3015 key field of the hash table.
3016 Moved macro_args and blind_no_args...
3017 (m4_token_data): ...to here.
3018 m4/macro.c (expand_macro): Added a name argument since the symbol
3019 name is no longer copied into each struct m4_symbol. Modified all
3021 (collect_arguments): Ditto.
3022 * modules/m4.c (set_trace): Ditto.
3023 * modules/gnu.c (builtin_symbols): Updated.
3024 * src/freeze.c (produce_symbol_dump): Much improved in light of
3025 the improved symbol table layout.
3027 2001-09-01 Gary V. Vaughan <gary@gnu.org>
3029 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
3031 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
3032 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
3033 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
3034 SYMBOL_HANDLE): Ditto.
3035 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
3036 modules/gnu.c, modules/m4.c, src/freeze.c,
3037 src/main.c: Updated all references.
3039 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
3040 Automake 1.5 chokes on dynamic source file lists, Besides, it is
3041 already listed in m4_LDADD... how did that ever used to work?
3042 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
3044 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
3045 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
3047 * tests/m4: Don't call the m4 wrapper script with libtool, it
3048 works fine all by itself.
3050 2001-08-30 Gary V. Vaughan <gary@gnu.org>
3052 The experimental `changeword' feature never took off, and has
3053 no obvious advantages over `changesyntax' to compensate the
3054 enormous speed penalty it carries:
3055 * configure.in (ENABLE_CHANGEWORD): Removed.
3056 * m4/m4module.h (m4_set_word_regexp): Removed.
3057 * m4/m4private.h (m4_token_data): Removed original_text field.
3058 * m4/utility.c (m4_token_data_orig_text): Removed.
3059 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
3060 * m4/macro.c: Ditto.
3061 * src/main.c: Ditto.
3062 * modules/Makefile.am (changeword.la): Removed.
3063 * modules/changeword.c: File removed.
3064 * doc/m4.texinfo: References to changeword and --word-regexp
3066 * po/POTFILES.in: modules/changeword.c removed.
3067 * tests/atlocal.in (ENABLE_CHANGEWORD): Removed.
3068 * tests/builtins.at (changeword): Test removed.
3070 2001-08-30 Akim Demaille <akim@epita.fr>
3072 * bootstrap.sh: Create aclocal.m4 instead of modifying it.
3073 This also help having a single list of m4 files: in
3075 * config/Makefile.am (STANDARD_MACROS): Rename as...
3076 (ACLOCAL_MACROS): this.
3077 (list-standard-macros): Remove.
3080 2001-08-29 Gary V. Vaughan <gary@gnu.org>
3082 In an attempt to moderate my egomania...
3083 * tests/modules.at: Remove attributions.
3085 * tests/generate.awk: When making substitutions to "@&t@", either
3086 "&" or "\&" in the substitution string argument to gsub refer back
3087 to the matched text. "@\\&t@" seems to work though, Tests 43 and
3090 2001-08-29 Akim Demaille <akim@epita.fr>
3092 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)
3093 (include, indir, multiquotes, patsubst, pushdef/popdef, regexp)
3094 (sync-lines, trace, translit, undivert, wrap): Move to...
3095 * tests/builtins.at: this new file.
3096 * tests/others.at (Discard comments, import-environment): Move to...
3097 * tests/options.at: this new file.
3099 2001-08-29 Akim Demaille <akim@epita.fr>
3101 * tests/others.at (Freezing modules)
3102 (--module-directory: absolute path, modpath2, modpath3)
3103 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
3104 * tests/modules.at: here, new file.
3105 * tests/others.at, tests/generate.awk: Add a banner.
3106 * tests/testsuite.at: Adjust.
3107 (AT_CHECK_M4_FILTER): New, but unused.
3109 2001-08-29 Akim Demaille <akim@epita.fr>
3111 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
3113 * tests/others.at (wrap): Inline wrap.m4.
3114 (shadow): Inline shadow.m4.
3115 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
3116 * tests/m4: Simplify.
3118 2001-08-29 Akim Demaille <akim@epita.fr>
3120 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
3123 2001-08-29 Akim Demaille <akim@epita.fr>
3125 * tests/generate.awk (normalize): s/@__@/@&t@/.
3127 2001-08-28 Akim Demaille <akim@epita.fr>
3129 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.
3131 2001-08-28 Gary V. Vaughan <gary@gnu.org>
3133 * bootstrap (generate.awk): Generate test cases with new script.
3135 2001-08-27 Akim Demaille <akim@epita.fr>
3137 * tests/Makefile.am (installcheck-local): Don't use
3138 `dc_install_base' which is not visible here, but `exec_prefix'
3139 which is clearly the RT anyway.
3140 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
3141 related to testing a now installed m4.
3142 * tests/m4: Do it here.
3144 2001-08-27 Akim Demaille <akim@epita.fr>
3146 * tests/others.at (indir): Formatting change.
3148 2001-08-27 Akim Demaille <akim@epita.fr>
3150 * tests/Makefile.am (installcheck-local): New.
3151 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
3153 Prefer options over envvars.
3154 * src/main.c (main): First bug caught by the test suite (yeah!):
3155 --batch lacked a `break' which resulted in an accidental
3156 invocation of --discard-comments.
3158 2001-08-27 Akim Demaille <akim@epita.fr>
3160 * tests/others.at (capitalize, changeword, comments, ddivert)
3161 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
3162 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
3163 (sysv-args, trace, translit, undivert): Don't rely on files in
3164 examples/: AT_DATA them.
3166 2001-08-27 Akim Demaille <akim@epita.fr>
3168 Let the test suite use a wrapper around the not installed m4 to
3169 pretend it is (installed).
3171 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
3172 such a way that m4 does not process them.
3173 * configure.in: The package name seems to be `m4', not `M4'.
3175 * tests/atlocal.in (at_package, M4): Remove.

3184 2001-08-27 Akim Demaille <akim@epita.fr>
3186 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
3187 Don't use aclocal: it's written by hand.
3188 * aclocal.m4: m4_include all the files instead of being built by
3190 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
3191 until it reads the traces by itself.
3192 * configure.in: Require Autoconf 2.42c as we are now using
3193 AC_CONFIG_TESTDIR instead of AT_CONFIG.
3194 Catch unexpanded `jm_' macros.
3195 * config/atconfig.m4: Remove.
3196 * config/error.m4: new.
3197 * config/Makefile.am: Ship the files included by aclocal.m4.

3208 2001-08-20 Gary V. Vaughan <gary@gnu.org>
3210 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
3211 Robert Collins, building on Cygwin no longer requires Windows
3212 import and export symbol decorations.
3213 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.
3214 * m4/error.h (M4_SCOPE) [cygwin*]: Ditto.

3227 2001-08-20 Gary V. Vaughan <gary@gnu.org>
3229 Ansify the source. Previously we had a mix, where my code was
3230 in a K&R compatible style, and the preexisting code was in ANSI
3231 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
3232 and now the code base is much cleaner.

3235 VOID macro and all users.

3275 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
3276 * modules/m4.c (undivert): Disable the possibility of undiverting
3277 several files at once: it is not documented, it is inconsistent
3278 with the other macros, it can be straightforwardly mocked by
3279 several invocations, and most importantly, it prevents the
3280 possibility of other kinds of extension.
3281 Use `m4_numeric_arg'.
3283 2001-08-20 Akim Demaille <akim@epita.fr>
3285 * examples/include.m4: Typo.
3286 * tests/generate.awk: Really add it.
3287 * tests/Makefile.am: Adjust.
3288 * tests/others.at (Discard comments): It sure fails without `-c'.
3289 (include, undivert): Add -I examples/.
3291 2001-08-20 Akim Demaille <akim@epita.fr>
3293 Use sprintf, not ecft and friends since it is standard, portable,
3294 simplifies the code, and since the latter is even deprecated
3295 according to the GNU libc documentation.
3297 * modules/format.c: Drop evct support.
3299 2001-08-19 Gary V. Vaughan <gary@gnu.org>

3443 Drop Autoconf 2.13 compatibility.
3445 * configure.in (changeword): No need to undefine it, as anyway if
3446 it's defined, M4sugar moved it as m4_changeword.

3448 (m4_pattern_allow): As it exists in 2.50, just use it.
3449 (AC_OUTPUT): Split in AC_CONFIG_FILES and AC_CONFIG_COMMANDS.
3450 Don't handle Gettext's duties, let it handle them.

3504 (M4FINISH_HANDLER): And similarly for finish functions.
3505 * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER
3506 -- Add indirection to the CONC macro so that arguments are
3508 * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
3509 * modules/shadow.c (m4_init_module): Ditto.

3521 instead of the old module argument.
3522 (m4_builtin_table_install): Ditto.
3523 * modules/load.c (m4_resident_module): Removed. This is no
3524 longer implemented as a magic symbol...
3525 * modules/m4.c (m4_resident_module): Ditto.
3526 * modules/load.c (M4INIT_HANDLER): ...the module init function now

3539 (libm4_la_SOURCES): Delete list.c reference.

3542 various tokens that are passed between functions.
3543 (struct m4_symbol): Removed the module field. The
3544 module association does not belong with the symbol...
3545 * m4/input.c (struct m4_builtin): ...it belongs with the builtin
3546 that the module implementation code is from. Added a handle
3548 (m4_push_macro): Add a `handle' argument. Changed all callers.

3564 (CDPATH) Neutralize.
3565 * tests/gethem: Use them.
3567 2001-08-14 Gary V. Vaughan <gary@gnu.org>

3584 shell variable m4_cv_func_obstack_h.
3585 * tests/defs (M4): Be more careful about relative path to libtool
3586 script and m4 binary by using $srcdir.
3588 * src/main.c (main): Use lt_dlinsertsearchdir to prepend -M
3589 optargs to the existing libltdl search path.
3590 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.
3591 * m4/ltdl.c: Updated.
3593 * config/ltmain.sh: Ditto.
3595 2001-08-11 Gary V. Vaughan <gary@gnu.org>
3597 * src/main.c (main): Add `-b' (for `batch') mode switch to force
3598 interactive mode off.

3609 (M4_AC_FUNC_OBSTACK): Rename `m4_obstack' and `m4_obstack_h'.

3651 * modules/format.c (format): Formatting for %f was not
3652 interpreting the position of the decimal point correctly for
3655 2000-12-01 Gary V. Vaughan <gary@gnu.org>
3657 * TODO: Removed m4exit bug.
3658 * modules/load.c (m4_resident_module): Make this module resident.
3659 * module/m4.c (m4_resident_module): Ditto.
3660 * m4/modules.c (m4_module_load): Use new ltdl resident modules
3661 feature to mark modules as resident if they export
3662 `m4_resident_module' as TRUE.
3663 (m4_module_unload): Do not remove resident modules, and take care
3664 with symbol insertion and deletion with resident modules.
3665 * m4/ltdl.c, m4/ltdl.h: Update to latest unreleased versions to
3666 use resident modules feature.
3668 2000-11-30 Gary V. Vaughan <gary@gnu.org>
3670 * TODO: Updated. Removed some cruft that has since been fixed
3671 or implemented. Added some more entries.
3674 * modules/README: Updated.
3675 * doc/m4.texinfo: Updated.
3677 * modules/gnu.c (builtin_functions): Make indir orthogonal to
3678 builtin, in that each is recognised as a macro only with parameters
3679 (builtin_indir): Passing 0 arguments is now an error, as with
3682 * src/main.c (usage): Added missing description of `-c' option.
3684 2000-11-29 Gary V. Vaughan <gary@gnu.org>
3686 Consolidate the myriad of dispersed test scripts into the
3687 tests subdirectory. I think I now have all the file where I
3688 want them, so there shouldn't be anymore upheaval =)O|

3729 Move the implementation of GMP support for the mpeval() builtin
3730 into a loadable module that depends on libgmp. mpeval() and
3731 eval() share a common parser, now in m4/evalparser.c; the code
3732 in m4/numb.c and m4/numb.h is now physically split between
3733 m4/eval.c (the eval() backend) and modules/mpeval.c (the
3734 mpeval() backend), rather than being differentiated by cpp
3735 macros and multiple inclusion. The mpeval module is always
3736 built but will generate an diagnostic if it is used from an
3737 installation that didn't link in the gmp library.
3738 * modules/Makefile.am: build and install the new mpeval module.
3739 * modules/mpeval.c: Now contains the former parts of m4/numb.c
3740 and m4/numb.h that are required for gmp support in mpeval().
3741 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
3742 * m4/evalmp.c: Removed.
3743 * m4/m4module.h: Removed conditional prototype for
3745 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
3746 and m4/numb.h that do not rely on gmp.
3747 * m4/evalparse.c: New file, contains the shared parts of the
3748 eval() and evalmp() parser implementations, and is no longer
3749 unencumbered by cpp magic to uncover the right parts.
3750 * m4/numb.h: Removed. It's former contents are split between
3751 m4/eval.c and modules/mpeval.c.
3754 * tests/other-tests/changeword.test: New test. Rudimentary
3755 testing of changeword builtin runs only if --wnable-changeword
3756 was used at configure time.
3757 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
3758 alternation correctly. Split into two expressions to compensate.
3759 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
3760 * modules/Makefile.am: Build changeword module.
3761 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
3762 only when --enable-changeword was passed to configure.
3763 (builtin_changeword): If --enable-changeword was not used, then
3764 report that changeword() builtin has no support in m4 binary.
3766 2000-11-28 Gary V. Vaughan <gary@gnu.org>
3768 * src/main.c (main): Fixed a particularly nasty bug is
3769 user_search_path setting -- the -M flag processing must be
3770 extremely careful with search path ordering, or else the default
3771 installed module directory (possibly containing modules from a
3772 previous release) is placed earlier in the search path than any -M
3773 arguments (which are relied upon to load uninstalled modules with
3774 most of the tests in the regresion suite).
3776 * modules/load.c (builtin_load): Nasty hack to prevent adding
3777 symbols to symtab again if a module is loaded more than once.
3778 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
3780 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
3781 possible NULL pointer dereference.
3783 * m4/module.c (m4_module_find_by_modname): Renamed from
3784 m4_module_modname_find. Fixed all references.
3785 (m4_module_find_by_builtin): New function.
3787 * modules/modfreeze.test: load the `load' module with each
3789 * src/freeze.c (produce_frozen_state): Simplified in light of
3790 module field in m4_symbol. Allow a third argument for text macros
3791 to name the originating module.
3792 (reload_frozen_state): ditto.
3793 * m4/m4module.h: Fixup prototypes.
3794 * m4/builtin.h (m4_builtin_define): Add a module argument so
3795 that symbols can be registered against the defining module.
3796 (m4_macro_define): ditto.
3797 * m4/m4private.h (m4_symbol): Make the module field const to save
3798 on casting in the rest of the code.
3799 (SYMBOL_MODULE): New macro.
3801 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
3802 symbol reference maintenance bugs when removing a symbol from the
3805 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
3807 2000-11-27 Gary V. Vaughan <gary@gnu.org>
3809 * configure.in (m4_cv_func_obstack): A better check for whether
3810 libc has an obstack implementation.
3811 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
3813 * configure.in (--with-modules): Changed semantics. This
3814 option is now used to list modules to be preopened.
3815 * src/m4.h: #include "ltdl.h" unconditionally.
3816 * src/main.c: Removed all dependencies on WITH_MODULES.
3817 * src/freeze.c: ditto.
3818 * modules/Makefile.am: ditto.
3819 * m4/m4.c (builtin_m4exit): ditto.
3820 * modules/modpath1.test: ditto.
3821 * modules/modpath2.test: ditto.
3822 * modules/modpath3.test: ditto.
3823 * modules/modpath4.test: ditto.
3824 * modules/modtest.test: ditto.
3825 * modules/shadow.test: ditto.
3826 * modules/unload.test: ditto.
3828 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
3829 comes up on demand in LTLIBOBJS now.
3830 * configure.in (getopt_long): Creating and relying on a link for
3831 getopt.h on hosts with no getopt_long() of thier own works
3832 correctly now. This is necessary so that callers of getopt_long()
3833 can simply `#include <getopt.h>': the naive way of doing this
3834 would end up using our own getopt.h and the installed
3835 getopt_long(), which is asking for trouble!
3836 (obstack_init): A similar argument applies to obstack.h and
3839 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
3840 On Solaris-2.5 (at least) the native dlopen implementation
3841 gets confused about m4.o when looking for module "m4". This
3842 version always looks for .la an .$lib_ext suffixed names first
3843 to work around the problem. Sigh.
3845 * po/POTFILES.in: Take account of these file movements.
3846 * src/Makefile.am (m4_SOURCES): removed eval.c.
3847 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
3848 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
3849 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
3850 * modules/m4.c (builtin_eval): Use m4_evaluate().
3851 * m4/eval.c: Moved here from src/eval.c to facilitate
3852 implementation of eval() builtin as part of the `m4' loadable
3854 (m4_evaluate): renamed from evaluate for namespace cleanliness.
3855 * m4/numb.c: Moved here from src/numb.c, since it is #included
3856 into eval.c at compile time.
3857 * m4/m4module.h (m4_evaluate): Added prototype.
3858 * src/m4.h (evaluate): Removed prototype.
3860 2000-11-25 Gary V. Vaughan <gary@gnu.org>
3862 * modules/perl.c (builtin_perleval): Use PL_na for
3863 compatibility with perl-5.6.
3865 * src/main.c (main): It is now safe to
3866 ``m4_module_install("m4")'', without tripping over the m4
3868 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
3869 versions having fixed the insidious module search order bug.
3871 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
3872 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
3874 * configure.in: Figure out whether to use the installed
3875 getopt.h or the supplied one.
3876 * src/Makefile.am: ditto.
3878 * po/POTFILES.in: List files in their new positions.
3880 * config/ltmain.sh: This needs to be checked in to match the
3881 libtool macros copied to acinclude.m4 (until a released
3882 libtool copes with m4's needs).
3883 * bootstrap: Run gettextize.
3885 2000-11-24 Gary V. Vaughan <gary@gnu.org>
3887 * AUTHORS: Added my details.
3890 * bootstrap: temporary update until released libtool catches up.
3892 * All files: Use new GNU GPL copyright blurb with current contact
3895 * configure.in (LTLIBOBJS): Use canonical code for calculation of

3906 ``unload'' builtins.

3926 * modules/gnu.c: New file implementing a new loadable module wuth
3927 definitions for all the gnu extension builtins.
3928 * modules/format.c: Moved here from src/format.c. Now included
3931 * src/main.c (main): Load the traditional module if m4 was
3932 started in `no_gnu_extensions' mode.
3933 * modules/traditional.c: New file implementing the ``unix'' macro,
3934 required when m4 is executed in traditional mode, as a loadable
3937 * src/main.c: Renamed from m4.c to avoid confusion with
3939 (main): Always load the m4 module.
3940 * modules/m4.c: New file implementing a new loadable module with
3941 definitions for all m4 builtins that are not gnu extensions.
3943 * m4/Makefile.am: Adjusted to take new files below into account.

3947 the migration of all builtin implementations to loadable modules.
3948 * m4/macro.c: Moved this file here from the src directory,
3949 renaming all exported symbols to use the prefix ``m4_''.
3950 * m4/builtin.c: ditto.

3952 * m4/symtab.c: ditto.
3953 * m4/debug.c: ditto.
3954 * m4/input.c: ditto.
3955 * m4/output.c: ditto.
3957 * m4/ltdl.h, m4/ltdl.c: ditto.
3958 * m4/utility.c: Odd functions moved here from files in the src
3959 directory to facilitate builtin migration.
3961 2000-08-12 Gary V. Vaughan <gary@gnu.org>
3963 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
3964 error message, to make translators' jobs a little easier.
3965 (builtin_builtin): ditto.
3966 (builtin_traceon): ditto.
3967 (builtin_traceoff): ditto.
3968 Reported by Akim Demaille <akim@epita.fr>
3970 * m4/Makefile.am (pkgincdir): Deleted. Use automake's built in
3971 pkgincludedir instead.
3973 * m4/m4module.h (rquote): Renamed with a prefix of `m4_' since

3993 Removed `Prev', `Next' and `Up' fields of all @nodes now that
3994 makeinfo calculates them for us, and to make any future
3995 reorganisation easier.
3996 (Frozen files): Document format version 2.
3997 `V' now takes argument `2'.
3998 `F' can take a single argument if symbol and builtin names
3999 are the same, or 3 arguments if the builtin is from a module.
4000 New `S' specification for saving syntax table contents.
4001 New `M' specification for saving loaded module names.

4092 (token_data_type): Renamed to `m4_token_data_t' for the same

4134 * modules/perl.m4: Example of using it.
4135 * modules/Makefile.am (perl_la_SOURCES): Build new perl module.
4137 * src/m4.c (main): Assume interactive mode if STDIN is connected
4139 Changed startup sequence slightly so that syntax is not
4140 initialised from here when loading a frozen file.
4142 * src/builtin.c: Much improved macro definition style.
4143 * src/m4private.h: Internal structures for m4_builtin and
4144 m4_macro instances. These are not exposed to module writers.

4149 (make_builtin_table): Build an internal builtin table from an
4150 external definition.
4152 * src/module.c (module_unload): Be extremely careful to remove
4153 builtins and macros that match the module being unloaded -- no
4154 longer assume that the top element can be removed incase another
4155 odule defines an identical name.
4156 * src/symtab.c (remove_table_reference_symbols): remove all symbol
4157 table entries which refer to a given builtin table.

4165 * configure.in: AC_SUBST INCLTDL and LIBLTDL, -with-modules flag:
4166 if set, enable WITH_MODULES and add modules to DLPREOPEN
4167 * examples/misc.test: redirect standard output
4168 * lib/Makefile.am: don't use DLLDFLAGS
4169 * lib/m4module.c: include necessary headers to silence GCC -Wall

4174 * modules/test.c: define symbol aliases before using them
4175 * po/de.po: update translation
4176 * src/Makefile.am: delete pathconf.h, set MODULE_PATH to
4177 pkglibexecdir, don't use DLLDFLAGS, add INCLTDL to INCLUDES and
4179 * src/m4.c: initialize libltdl's preloaded symbols via
4180 LTDL_SET_PRELOADED_SYMBOLS
4181 * src/module.c: libltdl's memory management must be initialized
4182 before calling lt_dlinit!, fix warnings
4184 2000-01-18 Gary V. Vaughan <gary@gnu.org>
4186 * README: Caveat about nls not supported by dll architecture on
4189 * TODO (MODULE SPECIFIC ISSUES): more ideas for the future.
4191 * tests/Makefile.am (stamp-TESTS): now works with VPATH.
4192 * src/Makefile.am (m4_LDADD): use $(builddir) for VPATH.
4193 * modules/Makefile.am (LIBS): ditto.
4194 (INCLUDES): search $(top_srcdir) (for eg. <m4/error.h>) and then
4195 $(top_srcdir)/m4 (for only <m4module.h>).
4196 * modules/shadow.test: fixed for VPATH.
4197 * modules/modtest.test: ditto.

4210 * acm4/ltdl.m4: Updated to latest from libtool cvs.
4211 * acm4/modules.m4: Remove code which duplicates ltdl.m4 and
4212 increment serial number.
4214 * Makefile.am (SUBDIRS): Moved @MODULES_DIR@ to compile before
4215 src dir and immediately after libm4 is built for confidence that
4216 it doesn't rely on the src directory.
4217 (SUBDIRS): Moved doc dir to the end since helptoman.pl and
4218 makeinfo stop the build on cygwin (because they don't work).
4220 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
4222 * m4/m4private.h: ...is not a public header, so moved to src.
4223 Add `#include <config.h>', `#define _COMPILING_M4' and
4225 * m4/Makefile.am (noinst_HEADERS): remove m4private.h.
4226 * src/Makefile.am (noinst_HEADERS): add m4private.h.
4227 * src/builtin.c: `#include "m4private.h"' now takes care of the

4246 (INCLUDES): Look first in $(top_srcdir) (for eg. <m4/error.h>),
4247 and then in $(top_srcdir)/lib (for eg. "m4private.h").
4248 * src/Makefile.am (m4_LDADD): replace libi/libm4.la with
4250 * m4/m4error.h: Renamed error.h, for installation to
4251 $prefix/include/m4..
4252 * m4/m4obstack.h: Renamed obstack.h, for same reason.
4253 * m4/m4regex.h: Renamed regex.h, for same reason.

4266 From Akim Demaille <akim@epita.fr>
4268 2000-01-17 Gary V. Vaughan <gary@gnu.org>
4270 * src/ltdl.c: Use access() to abort doomed module load attempts
4271 if module file does not exist.
4273 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
4274 getopt1.o will already be used if appropriate, so I moved getopt.c
4275 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
4277 * modules/modpath1.test: Use correct filename in header line.
4278 * modules/modpath2.test: ditto.
4279 * modules/modpath3.test: ditto.
4280 * modules/modpath4.test: ditto.
4282 Without these changes lt_dlopen("test") attempts to
4283 LoadLibrary("/bin/test") on Windows, which although harmless
4284 generates a spurious error message which spoils most of the tests:
4285 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
4286 (TESTS): s/test.test /modtest.test /
4287 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /
4288 (test_la_SOURCES, test_la_LDFLAGS): renamed to use modtest.
4289 * modules/modpath1.test: s/test.m4 /modtest.m4 /
4290 * modules/modpath2.test: ditto.
4291 * modules/modpath4.test: ditto.
4292 * modules/modpath3.test: s/-m test /-m modtest /
4293 * modules/shadow.m4: use {un,}loadmodule(`modtest').
4295 2000-01-16 Gary V. Vaughan <gary@gnu.org>
4297 * src/ltdl.c (find_file): Updated to new version with fixed memory
4298 allocation bug in `next'.
4299 * src/ltdl.h: updated to match.
4301 * modules/Makefile.am: Cleaned up and reordered.
4303 2000-01-16 René Seindal <rene@seindal.dk>
4305 * modules/Makefile.am (TESTS): New tests for the module system.
4307 * modules/*.test: New files.
4309 * src/m4.c (main): Added call to module_init().
4310 Treats -M and -m as the arguments -D -U and -t, ie deferred.
4312 * src/m4.h: Added declaration of module_init().
4314 * src/module.c (module_init): No longer static
4316 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
4317 Added to shut up automake about non standard libtool library
4320 * src/module.c: Disabled DEBUG by default.
4322 * modules/README: Changed example from unload.m4 to shadow.m4
4324 * modules/shadow.m4: Renamed from unload.m4
4326 * modules/Makefile.am (EXTRA_DIST): Removed unload.m4.
4328 * src/m4.c (main): Functionality for -m and -M were reversed.
4331 2000-01-12 Gary V. Vaughan <gary@gnu.org>
4333 * doc/help2man.pl: updated to version 1.020.
4335 * lib/COPYING.LIB: updated to version 2.1.
4337 * lib/m4module.h: restructure the M4_SCOPE code to work when
4338 creating a dll which links with libm4.la and both DLL_EXPORT
4339 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
4342 2000-01-11 Gary V. Vaughan <gary@gnu.org>
4344 Merged the following changes from my tree:
4346 1999-06-15 Gary V. Vaughan <gary@gnu.org>
4348 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
4349 ported to compile shared libs.
4351 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
4352 use `__declspec(dllimport)' when linking libm4.la on win32.
4353 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
4355 * configure.in (M4OBJS): Discover whether we need the shipped
4356 implementation of getopt_long.
4357 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
4358 main binary here, as opposed to the module library in lib/libm4.la.
4360 1999-06-14 Gary V. Vaughan <gary@gnu.org>
4362 * modules/README: Updated to describe the improved libltdl based
4364 * README (cygwin): Added some compilation notes for building m4
4365 correctly under cygwin.
4366 * TODO: Cleaned out the entries for the module system since they
4367 are now implemented.
4369 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
4370 all instances of __P with M4_PARAMS.
4372 * lib/getdate.h: removed unreferenced file.
4374 * lib/m4private.h: New file to define the private interface to the
4375 token_data struct, which must be shared between m4module.c, and
4376 builtin.c but not exported to modules built from the installed
4377 m4module.h since it's size changes depending on compile time
4380 * src/m4.h: Lots of stuff moved to lib/m4module.h.
4382 * lib/m4module.h: New file to define the interface available when
4383 compiling m4 modules.
4384 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
4385 necessary for module compilation into this new file.
4387 * lib/Makefile.am (include_HEADERS): install headers (renamed to
4388 avoid nameclash with other system headers) necessary for compiling
4390 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
4391 so that modules can include the (renamed) installed headers and
4392 be guaranteed a matching implementation.
4393 * lib/m4error.h: renamed from error.h.
4394 * lib/m4obstack.h: renamed from obstack.h.
4395 * lib/m4regex.h: renamed from regex.h.
4396 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
4397 implementation, simply include the shipped version
4398 unconditionally, otherwise it is hard for a module to know
4399 whether the m4obstack.h header it is using matches the
4400 implementation it ends up linking against.
4401 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
4404 1999-05-18 Gary V. Vaughan <gary@gnu.org>
4406 * examples/misc.test: Don't run this test on machines which don't
4407 have a root user in /etc/passwd (e.g. cygwin).
4409 * tests/get-them (/^@example$/): Error messages might have a
4410 ``.exe'' suffix to the program name, or else use the libtool
4411 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
4412 of these cases are now catered for when comparing error messages
4414 * tests/other-tests/*.test: ditto.
4415 * examples/*.test: ditto.
4417 * tests/defs (M4): use libtool execute mode.
4418 * examples/defs (M4): ditto.
4420 * tests/get-them (END): explicitly close any open file.
4421 (printthem): In a regular expression, '{' is the start of a repeat
4422 count! Use `[{]' for a literal open brace.
4423 (/^@node /): Don't use substr on a string shorter than the trim
4426 1999-05-17 Gary V. Vaughan <gary@gnu.org>
4428 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
4430 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
4432 2000-01-10 Andreas Schwab <schwab@suse.de>
4434 * tests/other-tests/gmp.test: Find config.sh in build directory.
4436 * configure.in: Find tests/mkconfig.sh in $srcdir.
4438 * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in
4439 <signal.h> (for SUS2 compliant systems).
4441 * src/stackovf.c: Check for HAVE_SIGINFO_T in addition to
4444 2000-01-10 René Seindal <rene@seindal.dk>
4448 * TODO, NEWS: Cleaned up and updated.
4450 * src/m4.c (main): New variable exit_status for exit status in
4451 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
4452 file cannot be read instead of EXIT_SUCCESS.
4454 * src/builtin.c (m4_indir): Changed error message to help
4455 translators (from Akim Demaille <demaille@inf.enst.fr>).
4457 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
4460 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
4463 * src/input.c (match_input): Reordering of code, to avoid multiple
4464 calls to push_string_init() from obstack_grow(), which can happen
4465 with some compilers (found and fixed by James Bonfield
4466 <jkb@mrc-lmb.cam.ac.uk>).
4468 * src/stackovf.c: Added prototypes for ultrix.
4469 (setup_stackovf_trap): Added __P to cast.
4470 (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>)
4472 2000-01-09 René Seindal <rene@seindal.dk>
4474 * doc/m4.texinfo (Changequote): Added comment about changing
4475 quotes when the old quote is a part of the new.
4477 * src/builtin.c (expand_ranges): Added break after trailing dash.
4478 This caused misbehavious on some systems (found and fixed by Akim
4479 Demaille <demaille@inf.enst.fr>).
4481 * AUTHORS: Thomas Tanner included
4483 * acconfig.h: Added entry for ss_sp (see below).
4485 * configure.in (use_stackovf): Added check for stack_t with member
4486 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert
4487 <eggert@twinsun.com>).
4489 * doc/m4.texinfo (Frozen files): Added a simpler example for
4490 generating frozen files from several input files.
4492 1999-11-14 Paul Eggert <eggert@twinsun.com>
4494 * po/POTFILES.in: Add lib/getopt.c, lib/obstack.c,
4495 lib/regex.c, lib/xmalloc.c.
4497 1999-11-10 René Seindal <rene@seindal.dk>
4499 * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal.
4501 * src/module.c: reindented.
4502 (module_load): return if this is a repeated load of same module.
4503 (module_init): slight change of logic to avoid repeated
4504 initialisation debug messages.
4506 * Makefile.am (DIST_SUBDIRS): Added to ensure modules/ is included
4507 in the distribution.
4509 * modules/Makefile.am (test_la_LDFLAGS): set to -module to silence
4510 automake warnings about missing lib prefix.
4511 (time_la_LDFLAGS): ditto
4512 (stdlib_la_LDFLAGS): ditto
4514 1999-11-10 Paul Eggert <eggert@twinsun.com>
4516 * src/m4.h: Include error.h, since our macros use error.
4517 * src/m4.c: Don't need to include error.h.
4519 1999-11-09 Paul Eggert <eggert@twinsun.com>
4521 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
4522 and zero, as Solaris 7 cc does.
4523 (bcopy): Remove macro; no longer needed with new obstack.h.
4525 * src/output.c (freeze_diversions): Don't assume that a
4526 diversion size can fit in `int'. Check for diversion file
4527 size too large to be printed with `unsigned long'.
4529 * src/Makefile.am (CFLAGS): Omit -Wall.
4531 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.
4533 * src/debug.c (trace_format):

4536 * src/freeze.c (produce_frozen_state):
4537 Don't assume string lengths fit in int.
4539 1999-10-13 René Seindal <rene@seindal.dk>

4542 (ALL_LINGUAS): Added Czech translation (cs).
4544 1999-03-30 Gary V. Vaughan <gary@gnu.org>
4546 * src/builtin.c: moved module loading functions into...
4547 * src/module.c: entirely new implementation using libltdl.
4548 * po/POTFILES.in: added src/module.c.
4549 * modules/Makefile.am (LTLIBRARIES): Removed lib prefix as these
4550 are modules, not linktime libraries.
4551 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
4552 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
4553 avoidance on exported symbols.
4554 * modules/test.c (m4_macro_table, m4_init_module,
4555 m4_finish_module): ditto.
4556 * modules/time.c (m4_macro_table): ditto.
4558 * modules/time2.m4: new file which requires command line loading
4560 * src/m4.c (--load-module): dynamically load named runtime module
4561 into running executable before reading the source.
4562 (--module-directory): prepend a directory to the module search
4564 (module_init()): Do this the first time we load a module instead;
4565 if the module subsystem is broken normal m4 scripts can still run.
4566 * src/m4.h (install_builtin_table): is now exported.
4568 1999-03-26 Gary V. Vaughan <gary@gnu.org>
4570 * src/module.c: removed. No longer required.

4581 * src/Makefile.am (MAINTAINERCLEANFILES): ditto.
4582 * tests/Makefile.am (MAINTAINERCLEANFILES): ditto.
4584 * acinclude.m4: removed. `aclocal -I acm4' handles this much
4586 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
4587 * acm4/gettext.m4: removed. It causes a multiple definition vs.
4588 the installed gettext.m4 file when running aclocal.
4590 1999-03-25 Gary V. Vaughan <gary@gnu.org>
4592 * configure.in (AM_INIT_AUTOMAKE): bumped version number to
4593 distinguish this from the last prerelease.
4594 (AC_LIBLTDL_CONVENIENCE): build libltdl as a convenience library
4595 in its own subdirectory.
4597 * modules/Makefile.am (*_SOURCES): renamed to use libtool's "no
4598 lib prefix on a module" feature.
4599 (LDFLAGS): Added `-module -avoid-version' flags to build
4600 versionless module libraries.
4601 * src/builtin.c (m4_load_module): use libltdl.
4602 (module_unload_all): use libltdl.
4603 * src/m4.c (module_init): initialise module loading on demand for
4604 better diagnostics, and so that m4 will still work even if
4605 the module code is broken.
4606 * src/m4.h (module_init): removed. No longer relevant.
4607 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on
4608 exported symbols for compatibility with dlpreopening.
4609 * modules/test.c (m4_macro_table, m4_init_module,
4610 m4_finish_module): ditto.
4611 * modules/time.c (m4_macro_table): ditto.
4613 * bootstrap: New file. Runs all the autoutils in the right order
4614 after a fresh checkout, or a make maintainer-clean.
4616 1999-02-18 Akim Demaille <demaille@inf.enst.fr>
4618 * src/builtin.c (dump_symbols): New function, factoring common
4619 content of m4_dumpdef and m4_symbols.
4620 (m4_dumpdef): Use it.
4621 (m4_symbols): New function, implementing `symbols'. Use it.
4622 * doc/m4.texinfo: Fixed missing commas after @xref, so that the
4623 file compile with modern makeinfo.
4624 (Symbols): New node, documenting symbols.
4625 (direntry): Modernize.
4627 1998-12-11 René Seindal <rene@seindal.dk>
4629 * src/builtin.c (predefined_tab): New predefined macros
4630 __m4_changeword__, __m4_gmp__ and __m4_modules__ for testing for
4631 configure time options.
4633 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
4635 * src/module.c (module_try_load): Don't try to be clever and
4636 overwrite argument string. Instead allocate all constructed
4637 strings locally, since they can have arbitrary lengths. Make
4638 arguments pointers to const.
4639 (module_search): Simplify due to above change.
4641 1998-11-29 René Seindal <rene@seindal.dk>
4645 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): New tests.
4647 * tests/other-tests/import-environment.{m4,test}: New test.
4649 * tests/other-tests/discard-comments.{m4,test}: New test.
4651 * doc/m4.texinfo (Invoking m4): Updated for --discard-comments.
4653 * src/m4.c (main): New option -c --discard-comments.
4654 New global variable discard_comments.
4656 * src/m4.h (token_type): New TOKEN_NONE for tokens to be
4657 discarded, ie never returned from next_token().
4658 Added declaration of discard_comments.
4660 * src/input.c (next_token): Now loops until token type is not
4661 TOKEN_NONE. Comments are now given this type when comments should
4664 * doc/m4.texinfo (Invoking m4): Updated for --import-environment
4667 1998-11-28 René Seindal <rene@seindal.dk>
4669 * src/m4.c (main): New option --import-environment (no single
4672 * When configured with --with-gmp both the normal (fast) eval()
4673 and the gmp aware mpeval() are defined. To restore previous
4674 bahaviour use "define(`eval', defn(`mpeval'))".
4676 * tests/other-tests/gmp.m4: Changed to use mpeval().
4678 * src/evalmp.c: New file for compiling eval.c as gmp aware.
4679 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
4681 * src/eval.c: Now includes "numb.c" directly. Everything in this
4682 file must by static, except evaluate(), which is changed to
4683 mp_evaluate() if USE_GMP in force.
4685 * src/numb.c: Changed to be included by eval.c instead of being
4686 compiled separately. Everything is declared static.

4702 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
4704 1998-11-27 René Seindal <rene@seindal.dk>
4706 * Error messages now always print program name before input file
4707 name as specified by GNU coding standards. Reported by Akim
4708 Demaille <demaille@inf.enst.fr>.
4710 * doc/m4.texinfo (Include): Change due to changed error message
4714 * tests/get-them: Minor change to sed script due to changed error
4717 * src/m4.c (print_program_name): New func used to print program
4718 name, input file and line number in error (). Used as an

4730 warning of ambiguous 'else'.
4732 * src/module.c: Inserted search path code from path.c modified to
4734 (module_init): Configured default path used only if M4MODPATH is
4736 (module_try_load): Now reads libMODULE.la as generated by libtool

4749 included gettext, as <libintl.h> might not be found
4750 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
4752 1998-11-22 René Seindal <rene@seindal.dk>
4754 * src/output.c (insert_diversion): Fixed bug that might cause m4
4755 to read from standard output! Triggered by input
4756 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
4757 so now 'undivert(0)' does nothing.
4759 1998-11-18 René Seindal <rene@seindal.dk>
4763 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
4764 could be changed when compiling a illegal regexp, causing later
4765 use of the regexp to dump core.
4767 * src/module.c (module_load): Changed error message to conform to
4770 * src/m4.c (usage): Added message about reporting bugs.

4785 renamed when installed.
4787 * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
4788 USE_SHL_LOAD to HAVE_SHL_LOAD
4790 * src/builtin.c (shipout_string): Now tests for a NULL string.

4806 getpwuid, hostname, rand, srand, getenv, setenv, unsetenv, uname.
4808 * src/builtin.c (shipout_string): New convenience function for
4809 builtins and modules.

4820 These two are now initialised by autoconf macros.
4822 * src/path.c (module_env_init): MODULE_PATH is always on the
4825 * src/Makefile.am: Now generated pathconf.h which defined the
4826 default MODULE_PATH.
4828 * configure.in (pkglibexecdir): Added defintion of pkglibexecdir,
4829 where modules are installed.
4831 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
4832 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
4833 build and install automatically, and it is prepared for other
4834 interfacec than dlopen().
4836 * src/builtin.c (predefined_tab): Added __m4_version__ for the
4837 current version of GNU m4. It is a GNU extension.
4839 1998-11-14 René Seindal <rene@seindal.dk>

4869 * tests/Makefile.am (GENERATED_TESTS): Renamed gentest to
4872 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): Added manually
4873 maintained tests in tests/other-tests. These currently tests for
4874 8-bit transparency, multiple precision arithmetic and sync-line
4875 output. Test for stackoverflow detection does not work.

4917 1998-10-07 René Seindal <rene@seindal.dk>
4921 * tests/Makefile.am (GENERATED_TESTS): Changed .m4 extension to
4922 .test, as the files are no longer just m4 input.
4924 * tests/get-them (FILE): Changed .m4 extension to .test.
4926 * src/m4.h (token_type): New token type TOKEN_SPACE introduced.
4927 Otherwise quoted strings with leading whitespace first in a macro

4931 (expand_argument): Do.
4933 * src/input.c (next_token): SPACE and NUM/OTHER characters are only
4934 grouped together iff both quote and comment strings are single
4935 character. Otherwise they might include a comment/quote leader.
4936 (next_token): Returns new token type TOKEN_SPACE.
4938 * src/builtin.c (push_builtin_table): New function to push a
4939 builtin_table on the stack without installing its contents.
4940 (find_builtin_by_name): Added call to push_builtin_table() if
4941 reading frozen files. Otherwise the builtins named in the frozen
4942 files could not be found.

4945 1998-10-04 René Seindal <rene@seindal.dk>
4949 * configure.in (ALL_LINGUAS): Added Polish pl.po
4951 1998-10-03 René Seindal <rene@seindal.dk>

4963 skip_space, bad_argc), and the macros ARG() and DECLARE().
4965 * src/builtin.c (install_builtin_table): New function. Each
4966 module brings in a builtin_table, which is pushed on a stack.
4967 (struct builtin_table): New struct for list of builtin_tables.
4968 (m4_loadmodule): New function to implement builtin "loadmodule".
4969 (shipout_int): No longer static, to be used by modules.

4987 * Makefile.am (EXTRA_DIST): Added modules/* since modules/ is not
4990 * configure.in: Added modules/Makefile to AC_OUTPUT.
4992 * configure.in: Added code to implement --with-modules. Tests for
4995 * acconfig.h: Added WITH_MODULES
4997 1998-10-02 René Seindal <rene@seindal.dk>
4999 * examples/Makefile.am (pkgdata_DATA): Removed special target for
5000 check and variables TESTS. These tests are now run from the
5003 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
5004 directory. The files stay there but the tests are run from the
5007 * tests/Makefile.am (EXTRA_DIST): Added run-test.
5009 * tests/run-test: New file. Run a test manually
5011 * tests/Makefile.am, tests/get_them: Moved automatically generated
5012 tests (from the manual) to sub directory tests/gentest/. The
5013 tests/ directory had gotten a bit messy.
5015 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
5017 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\

5033 `C'. Reported by Ulrich Drepper.
5035 * Makefile.am (SUBDIRS): Removed checks directory
5036 * configure.in (AC_OUTPUT): Removed checks/Makefile
5038 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
5039 the space when m4.texinfo is edited and whitespace.el is active.
5040 (Defn,example): idem.
5042 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
5044 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
5045 ../COPYING. ../Makefile is a file which is certainly present when
5046 test is executed in testSubDir. One can't be sure that the COPYING
5047 file is in .. or ../.. in all situations, the ../Makefile is
5050 * doc/m4.texinfo (Include): adjusted expected test output
5051 according to new tests, i.e. the input will always come from the
5052 file `in' created by the test.
5054 * tests/Makefile.am: Added three lines at the top to get
5055 esyscmd.1.test working.
5057 * tests/get-them: modified to generate clearer tests who will need
5058 less maintenance when new test examples are created in
5059 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
5060 need the generic file `defs') shell scripts creating `in', `ok',
5061 `out' and when apropriate `okerr' and `err' in the directory
5062 `testSubDir' when executed. The compare of `ok' and `out'
5063 (and of `okerr' and `err') will be the exit status of the test.
5064 `out' must match `ok' (and `okerr' must match `err') for the test
5067 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
5068 the tests generated by tests/get-them getting it input normally
5069 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
5070 (dot) before the numeric part) is reserved for all other (hand
5071 written) tests. The `+' means one or more times.
5073 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
5075 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
5076 supported short man page to refer to info documentation
5077 * helptoman.pl: added
5078 * configure.in: AC_PATH_PROG(PERL,perl)
5079 * Makefile.am (SUBDIRS): doc after src
5081 * libitized with libit 0.5 from

5103 "changesyntax" to modify the syntax table.
5105 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax
5106 table. All categories are assigned a syntax code and tokens are
5107 read according to this table.
5109 1998-08-09 René Seindal <rene@seindal.dk>
5111 * src/numb.{c,h}: New files, implements multiple precision eval
5112 using GNU gmp. Originally submitted by John Gerard Makecki
5113 (johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.
5115 * doc/m4.texinfo (Eval): Added documentation for multiple
5116 precision arithmetic library support.
5118 * src/m4.{c,h}, src/eval.c, src/builtin.c, configure.in: Changes
5119 to accommodate multiple precision eval.
5121 1998-08-07 René Seindal <rene@seindal.dk>
5123 * src/input.c (MATCH, match_input), src/m4.h: changed definition
5124 of comment and quote strings to `unsigned int' to allow eight bit
5125 chars (reported by andrewb@zip.com.au (Andrew Bettison)).

5128 patch from Mike Howard <mike@clove.com>
5130 1998-08-06 René Seindal <rene@seindal.dk>
5132 * gettext.m4: corrected AM_WITH_NLS to handle use of installed

5139 * src/m4.h: Added ifdef ENABLE_NLS around include of <libintl.h>
5140 and _ macro. M4 now builds with --disable-nls.
5142 * src/m4.c (main): reintroduced textdomain(PACKAGE) to get gettext
5143 to look for right message catalogs. Call indef'ed by ENABLE_NLS.
5145 * configure.in (ALL_LINGUAS): Added complete list of translations:
5146 de fr it ja nl ru sv.
5148 1998-05-22 Erick Branderhorst <Erick.Branderhorst@asml.nl>
5152 * src/m4.c: #include <signal.h> not <sys/signal.h>.
5154 * src/Makefile.am: CFLAGS = -Wall @CFLAGS@.
5156 * checks/Makefile.am: explicit list tests in CHECKS.
5158 * configure.in, {,src,doc,lib,examples,checks}/Makefile.am,

5191 src/stackovf.c: Rename _ to __P.
5192 * src/m4.h: Declare _ as a macro returning its argument, or else,

5222 ANSIfying compiler flags, this is of no use to check it before.
5223 Reported by Alexander Lehmann.
5225 1994-11-01 François Pinard <pinard@iro.umontreal.ca>
5227 * src/macro.c (collect_arguments): Cast obstack arguments to
5228 (voidstar), so avoiding compiler warnings.
5229 Reported by Joseph E. Sacco.
5231 * src/freeze.c (produce_frozen_state): Cast printed lengths to

5269 ANSI2KNR, depending on the fact the compiler is ANSI or not.
5270 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
5271 Remove the sed filter after ansi2knr for debug.c. Use $O instead
5272 of $U, put underline in extensions rather than in basenames. Use
5273 implicit rules, now that regularity makes this possible.
5274 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
5275 of ansi2knr whenever it is needed.
5276 * configure.in: Adjusted for correct STACKOVF substitution.
5277 * src/debug.c (trace_format): When not __STDC__, use (...) as a
5278 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.
5279 Reported by David MacKenzie.
5281 * Makefile.in: Remove binprefix. Use transform_name instead.
5282 Reported by David MacKenzie.
5284 * doc/Makefile.in: Create version.texi, use it, clean it.

5289 * Makefile.in (all, install, uninstall): Depend on Makefile.
5291 * Makefile.in: For actions invoking $(MAKE) from within compound
5292 sh statements, exit non-zero if the sub-make fails. Otherwise,
5293 the top-level make may exit successfully when it should fail.
5294 Reported by Jim Kingdon.
5296 * {,/*}Makefile.in: Use && after all cd, in case they fail.
5298 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

5320 1994-10-01 François Pinard <pinard@iro.umontreal.ca>
5322 * configure.in: Do not add -O to CFLAGS for GNU C, now that
5323 configure does it automatically.
5324 Reported by Jim Meyering.
5326 1994-09-23 François Pinard <pinard@iro.umontreal.ca>
5328 * src/stackovf.c: Declare the handler_t typedef earlier in the

5331 casting sigsegv_handler.
5332 Reported by Robert Bernstein.
5334 * src/m4.c (main): Initialize program_name to argv[0] without

5341 Reported by Karl Berry.
5343 1994-09-14 François Pinard <pinard@iro.umontreal.ca>
5345 * lib/Makefile.in (mostlyclean): Added.
5346 (TAGS): Make in $(srcdir).
5348 * configure.in: Use `choke me' in test, like everywhere!
5350 * {doc,examples,lib,src}/Makefile.in (check): Deleted, as
5351 unreacheable and useless.
5353 * doc/Makefile.in (texclean): Deleted, merged in mostlyclean.
5355 * lib/Makefile.in (DISTFILES): Distribute TAGS.
5356 (distclean): Do not remove TAGS.
5357 (realclean): Remove it.
5358 * Makefile.in: Make TAGS in lib also, not just in src.
5359 Reported by Karl Berry.
5361 * Makefile.in (distclean, realclean): Instead of recursively
5362 calling $(MAKE) for the -local part, allow parallel execution of
5363 -recursive and -local, only delay the removal of config.status,
5364 which is repeated in both goals.
5366 1994-09-13 François Pinard <pinard@iro.umontreal.ca>
5370 * Makefile.in: Group all *clean-recursive goals in one, using sed
5371 to remove `-recursive' while calling make recursively. Also, use
5372 a subshell for each recursive $(MAKE).
5373 Reported by Jim Meyering.
5375 * src/m4.h (memcpy): Define with bcopy for BSD systems.
5376 Reported by Kaveh R. Ghazi.
5378 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS

5382 * configure.in: Use date instead of touch for stamp-h.
5383 * Makefile.in (stamp-h.in): Idem.
5385 * Makefile.in (distclean, realclean): Force serial execution of

5413 Reported by Jim Meyering.
5415 1994-09-06 François Pinard <pinard@iro.umontreal.ca>

5424 1994-09-02 François Pinard <pinard@iro.umontreal.ca>
5426 * lib/Makefile.in (install): Depend on all.
5428 1994-08-31 François Pinard <pinard@iro.umontreal.ca>

5431 Reported by Jim Meyering and John David Anglin.
5433 * Makefile.in (distclean-local): Delete config.log.
5434 Reported by Jim Meyering.
5436 Solidify frozen files with respect to -P:
5437 * src/m4.c: Have -P set prefix_all_buitins variable instead of
5438 calling a function by that name. Declare the variable.
5439 * src/m4.h: Adjust declaration for prefix_all_buitins.
5440 * src/builtin.c (builtin_init): Merge in functionality from
5441 previous prefix_all_buitins function, while making entries in the
5442 symbol table, but not modifying the builtin description itself.
5444 * src/freeze.c (reload_frozen_state): Add a useless `break;',
5445 because *many* compilers do not accept an empty `default:'.
5446 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
5447 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
5449 * configure.in: Use AC_TYPE_SIGNAL.
5450 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.
5451 Reported by Robert Bernstein.

5454 m4 in the src directory.
5455 * Makefile.in (check): Don't.
5456 Reported by Akiko Matsushita and Jim Meyering.

5459 functions, for implementing a global MAXIMUM_TOTAL_SIZE instead of
5460 a per buffer MAXIMUM_BUFFER_SIZE.
5462 * src/output.c (output_text): New function, for optimizing the
5463 output of strings of characters. Use it.
5465 1994-08-30 François Pinard <pinard@iro.umontreal.ca>
5467 * doc, src: New directories reorganizing the distribution.
5468 * doc/Makefile.in, src/Makefile.in, examples/Makefile.in: New
5470 * Makefile.in: Adjusted.
5471 * configure.in: Configure new Makefiles.
5473 * m4.h: Declare STRING typedef. Use it for comment and quote
5474 strings, adjusting all references. (This is the rudiments of a
5475 beginning for the eventual withdrawal of NUL terminated strings.)
5476 * output.c (shipout_text): Accept a length parameter, and use it.
5477 All callers adjusted.
5479 1994-08-29 François Pinard <pinard@iro.umontreal.ca>
5481 * m4.h: Include <unistd.h> if it exists.

5496 * m4.h, m4.c: Remove NDIVERSIONS and ndiversion related stuff.
5497 * m4.c: Still accept -N, but do nothing with it.
5498 Reported by David MacKenzie.
5501 * output.c (freeze_diversions): New function.
5502 * m4.h: Declare freeze_diversions.
5503 * freeze.c: Document frozen file format, revise it, call
5504 freeze_diversions to add diversions to frozen format, and code to
5505 reload them properly.
5506 * m4.c: Do not undivert automatically at end when status being
5507 frozen. Do not call builtin_init when reloading frozen state.
5509 Speed up diversion processing:
5510 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
5511 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
5512 structure and variables, cached variables out of output_diversion,
5513 reallocate_diversion_for and OUTPUT_CHARACTER.
5514 (shipout_text, make_diversion, insert_diversion): Adapted to new
5516 (insert_file): Use better buffering.

5521 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
5522 dist works from another build directory.
5524 1994-08-27 François Pinard <pinard@iro.umontreal.ca>
5526 * symtab.c (hack_all_symbols): Use hash_table_size instead of
5527 constant HASHMAX, for -H option to work better.
5529 * builtin.c (DECLARE): Simplify by using _ ().
5531 * freeze.c: New file.
5532 * Makefile.in: Compile it, distribute it.
5533 * m4.c: Recognize, document and process --freeze-state (-F) and
5534 --reload-state (-R) options. Pass a true flag to builtin_init
5535 only if no reloading some state.
5536 * builtin.c (define_builtin): Remove static specifier.
5537 (find_builtin_by_name): Remove static specifier.
5538 (builtin_init): Accept and obey a flag argument.

5550 1994-08-15 François Pinard <pinard@iro.umontreal.ca>
5552 * m4.c (long_options): Use "error-output", the dash was missing.
5553 Reported by Akiko Matsushita.
5555 1994-08-12 François Pinard <pinard@iro.umontreal.ca>
5557 * m4.h: Include <sys/types.h>.
5558 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
5559 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
5561 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
5563 * builtin.c (dump_args): Declare len as size_t, not int.
5565 * debug.c: Prototype the forward declaration of debug_set_file.
5567 * builtin.c (m4_undivert): Replace div by file, for avoiding the
5568 shadowing of this variable.
5569 * output.c (insert_diversion): Idem.
5571 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
5572 (input_init): Duplicate default quote and comment strings.
5573 (set_quotes): Free previous quote strings in all cases. Duplicate
5574 even default quote strings.
5575 (set_comment): Free previous comment strings in all cases.

5579 * Makefile.in (distclean-local): Also delete config.cache.
5581 * m4.c (usage): Reorganize the --help output by topic. Include a
5582 description for debugging flags.
5584 1994-07-29 François Pinard <pinard@iro.umontreal.ca>
5586 * configure.in: If sigaction is available and SA_ONSTACK defined,
5587 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
5588 defined, use sigvec. Else don't compile stackovf.c.
5589 * stackovf.c (setup_stackovf_trap): Idem.
5590 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
5593 1994-07-21 François Pinard <pinard@iro.umontreal.ca>

5597 1994-07-18 François Pinard <pinard@iro.umontreal.ca>
5601 1994-07-17 François Pinard <pinard@iro.umontreal.ca>
5603 * configure.in: Check for sigaction and sigvec. Add a new delayed
5604 check for RLIMIT_STACK, combine in the checking for getrlimit.
5605 All those things are not universally available.
5606 * stackovf.c: Split setting up the trap handler and catching
5607 signals, for better taking care of various configure outcomes.
5608 * examples/stackovf.sh: Correct a typo.
5609 Reported by Eric Backus, Jim Avera and Jim Meyering.
5611 1994-07-16 François Pinard <pinard@iro.umontreal.ca>
5613 * ansi2knr.c: New version sent by its author, Peter Deutsch.
5615 1994-07-15 François Pinard <pinard@iro.umontreal.ca>
5617 * Makefile.in: Modify so parallel make will not try making
5618 lib/libm4.a twice simultaneously.
5619 Reported by Jim Meyering.
5621 1994-07-14 François Pinard <pinard@iro.umontreal.ca>
5623 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
5624 error message, for when no code possibility exists. Even if this
5625 line is completely #ifdef'ed out, it brings a syntax error.
5626 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
5628 * Makefile.in (install): Have install depend on all too, for lib
5629 to be remade as needed.
5631 * examples/stackovf.sh: Try ksh, bsh and bash for shells
5632 providing ulimit, instead of using only ksh.
5633 Reported by Jim Avera and Joseph E. Sacco.
5635 1994-07-12 François Pinard <pinard@iro.umontreal.ca>
5637 * Makefile.in (check): Have it depend on all instead of m4. In
5638 this way, a change in lib will be detected and processed.
5640 * builtin.c (numeric_arg): Use strtol and verify the conversion,
5641 instead of using sscanf which stops as soon as there is a
5642 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
5643 and divert(1xyzzy) were all accepted without any warning or error
5645 * m4.h: Declare strtol as long if not including stdlib.h.
5646 * configure.in: Check for limits.h, and replace strtol if missing.
5647 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
5648 * lib/strtol.c: New file, from elsewhere.
5649 Reported by Andreas Schwab.
5651 1994-07-07 François Pinard <pinard@iro.umontreal.ca>
5653 * macro.c (expand_macro): Cast value to (boolean) prior to
5654 assigning it to traced.
5655 Reported by Tom McConnell.
5657 * Makefile.in (m4): Always make all in lib first.
5658 Reported by Jim Meyering.
5660 1994-07-06 Jim Avera <jima@netcom.com>
5662 * stackovf.c: Isolated OS-dependent sections; Improved portability,
5663 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
5664 handlers), and a default error message if the fault address is not
5665 available (when neither siginfo.h nor BSD sigcontext are supported).
5666 * configure.in: Changes for stackovf.h: Check for sigcontext,
5667 sigaction, sigstack, and define rlim_t as int if necessary.
5668 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
5669 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
5670 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
5672 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
5674 * configure.in: Use AC_SET_MAKE.
5675 * Makefile.in: Use @SET_MAKE@.
5676 Reported by Jim Meyering.
5678 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
5679 Reported by Ian Taylor.
5681 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
5683 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
5684 because siginfo.h is unrelated to standard headers, and siginfo.h
5685 is already checked for.
5686 Reported by Joseph E. Sacco.
5688 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
5690 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
5693 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
5695 * builtin.c (substitute): Use \& to represent this part of the
5696 string which was matched by the whole regexp, instead of
5697 representing the whole string. Any usage of \0 issues a warning
5698 and acts like \&, it will disappear in some subsequent release.
5700 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
5702 * m4.c: Complete prototype for forwarded declaration of usage.
5704 * input.c (init_macro_token): Correct own reference in error
5705 message. Previous name get_macro_func was referred to instead.
5706 (next_char): Correct own reference in error message. Previous
5707 name advance_input was referred to instead.
5709 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
5710 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
5711 and_term, not_term, logical_not_term, cmp_term, shift_term,
5712 add_term, mult_term, exp_term, unary_term, simple_term): Add
5713 prototype to forwarded declarations. Declare parameter v1 as
5714 eval_t * instead of int *. Same for local variable v2 in dyadic
5715 functions. Same for result in exp_term.
5716 * builtin.c (m4_eval): Declare value as eval_t instead of int.
5717 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
5718 unsigned_eval_t instead of unsigned int. Change casts accordingly.
5719 (shipout_int): Cast first argument of ntoa to eval_t.
5720 Reported by Thorsten Ohl.
5722 * macro.c: Complete the prototypes of forwarded expand_macro and
5724 Reported by Thorsten Ohl.
5726 * m4.h: Define voidstar as void * or char * depending on __STDC__.
5727 The Ultrix 3.1 compiler cannot do much with void pointers.
5729 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
5730 * m4.c (xfree): Replace void * by voidstar.
5731 Reported by Tom McConnell.
5733 * ansi2knr.1: New, from elsewhere.
5734 * Makefile.in (DISTFILES): Distribute ansi2knr.1
5736 * Makefile.in (stamp-h.in): Avoid running ./config.status if
5737 stamp-h does not exist yet. This avoids running it a second time
5738 just after the initial ./configure.
5739 Reported by David MacKenzie and Tom McConnell.
5741 * m4.h: Replace the enum debug_info declaration with a series of
5742 #define's. The Ultrix 3.1 compiler would otherwise need casting
5743 (int) to most references, when used in expressions.
5744 Reported by Tom McConnell.
5746 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
5748 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
5749 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
5750 calls the compiler. Previously, FP_PROTOTYPES was only calling
5751 the preprocessor; by not being subject to CFLAGS, this was
5752 discouraging those flags asking for ANSI compilation.
5753 * acconfig.h: Document HAVE_PROTOTYPES.
5754 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
5755 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
5756 Reported by Eric Backus.
5758 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
5759 from the environment. Default CFLAGS to -g if not set.
5760 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
5761 * lib/Makefile.in: Have CFLAGS substituted from configure.
5762 Reported by Eric Backus and Tom McConnell.
5764 * configure.in: m4_undefine changeword before using AC_ENABLE.
5766 * m4.h: Declare prototypes for error (for ANSI compilers only),
5767 prefix_all_builtins and reference_error.
5768 Reported by Tom McConnell.
5770 * input.c (set_word_regexp): Do not try to initialize the array
5771 test from a string, this does not work with non-ANSI compilers.
5772 Reported by Eric Backus.
5774 * Makefile.in (dist): Clean examples/ before saving it.
5775 (distclean-local): Also remove stamp-h.
5776 Reported by Eric Backus.
5778 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
5780 Reported by Tom McConnell.
5782 * checks/Makefile.in (clean): Depends on mostlyclean.
5783 (mostlyclean): New goal.
5785 1994-06-24 François Pinard <pinard@iro.umontreal.ca>
5787 * Makefile.in (DISTFILES): Distribute install.sh.
5788 * install.sh: New file, copied from elsewhere.
5789 Reported by Assar Westerlund and Kaveh R. Ghazi.
5791 1994-06-23 François Pinard <pinard@iro.umontreal.ca>
5793 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
5794 * acconfig.h: Explain ENABLE_CHANGEWORD.

5860 also tested it on a Sun Sparc workstation running SunOS 4.x.
5862 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
5863 49.format check, abusing a `union values' argument with sprintf
5864 without selecting the proper field. Now, save the formatting type
5865 first, delaying the fetch of the corresponding argument.
5866 Reported by Joseph E. Sacco and Tom Quinn.
5868 * format.c (format): Remove const from char *fmt declaration when
5869 not HAVE_EFGCVT, because a NUL may be forced into it.

5893 * acconfig.h: Declare USE_STACKOVF.
5894 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
5895 * m4.h: Declare setup_stackovf_trap().

5912 Reported by Jim Meyering.
5914 * builtin.c (m4_regexp): Reorganize the code for avoiding a
5915 warning from gcc about `repl' possibly used before defined.
5916 Reported by Jim Meyering.
5918 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
5919 Reported by Jim Meyering.
5921 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
5923 * m4.h: Move the conditional definition of volatile after the
5924 inclusion of system files, because they may define it first.
5926 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
5928 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
5929 get around a problem with Alpha make seeing a syntax error, there.

5950 1993-11-27 François Pinard <pinard@iro.umontreal.ca>
5952 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
5953 syserr() macro. Delete errref, add reference_error and M4ERROR.
5954 * m4.c: Replace errref, which was returning an input reference
5955 string, with reference_error, which prints it on standard error.
5956 * builtin.c, output.c: Use errno as second parameter to error,
5957 instead of using syserr() with %s.
5958 * *.c: Use M4ERROR instead of error: no more errref() with %s.
5959 Doing so, the program name appears after the input reference
5960 instead of before, which eases M-x next-error processing.
5962 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
5964 * checks/get-them: Escape braces with backslashes in patterns,

6006 expected is on the left and the obtained on the right.
6008 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR

6012 routines, add error_message_prefix routine.
6013 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
6014 warning with WARNING*, fatal with FATAL* and internal_error with
6016 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
6017 this is not needed anymore.
6019 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
6020 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
6021 and debug_message, add declaration for debug_message_prefix.

6323 * m4.h: Do not define index/rindex if already defined. If
6324 FALSE/TRUE are already defined, do not redefine them, but merely
6325 define boolean typedef to int.
6327 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
6328 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
6329 because some C compilers do not like connectives with #ifdef.
6330 * m4.h: Define `volatile' only if __GNUC__, instead of once for
6331 __GNUC__ and once for __STDC__.
6332 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
6334 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
6335 Makefile dependencies. Without it, make keeps destroying and
6336 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
6338 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
6339 to diversion/DIVERSION, this was a spelling error.
6341 * m4.c: Declare version[], remove #include "version.h".
6342 * version.h: Deleted.
6343 * Makefile.in: Remove references to version.h.
6345 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
6346 production, by using a simpler and more robust algorithm. This
6347 solves the problem of synclines sometimes written in the middle of
6348 an output line. Delete sync_line() and output_lines variable.
6349 * m4.h: Remove sync_line prototype and output_lines declaration.
6350 * input.c (next_char), output.c (shipout_text): Remove references
6352 * input.c (push_file, pop_file): Merely put the value -1 in
6353 output_current_line instead of calling sync_line, for delaying a
6354 single `#line NUM FILE' before next output line. Do not test
6355 for sync_output, because this is unnecessary clutter.
6356 * output.c (make_divertion, insert_divertion): Idem.
6357 * input.c: Rename must_advance_line to start_of_input_line, for
6360 * debug.c (trace_header): Select a new debug line format, which
6361 better complies with GNU standards for formatting error messages.
6362 With option `-dfl', M-x next-error might be used on the output.
6363 * m4.c (vmesg): Adjust format of error output to GNU standards.
6364 * m4.texinfo: Adjust examples for `make check' to work.
6366 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
6367 case for enum debug_info constants, which were all lower case.
6369 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
6371 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
6372 collected patches. I tried a few times using newer regex.[ch], it
6373 mysteriously stopped aborting with this one. Insecure feeling...
6374 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
6376 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
6378 * m4.c: Change `--no-warnings' to `--silent'.
6379 Reported by David MacKenzie.
6381 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
6382 leave it off for now. See comment in m4.c for justification.
6383 Reported by David MacKenzie.
6385 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
6386 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
6388 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
6390 * Makefile.in: Ensure recursive cleaning is done before local
6391 cleaning for all clean goals.
6393 * builtin.c (ntoa): Ensure the value is always interpreted as a
6394 signed quantity, whatever the radix is.
6396 1992-11-18 Jim Meyering <meyering@idefix>
6398 * builtin.c, format.c, input.c: Split long lines.
6399 * m4.c: Use typedef macro_definition instead of struct
6401 * symtab.c: Use typedef symbol instead of struct symbol.
6403 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
6405 * *.[ch]: Remove all trailing whitespace, in code and comments.
6407 * configure.in: Find some awk.
6408 * Makefile.in: Add $(AWK) to MDEFINES.
6409 * checks/Makefile.in: Transmit $(AWK) to get_them.
6410 * checks/get_them: Use $AWK instead of gawk. Add a close in the
6411 awk script when switching files, because without this, mawk runs
6412 out of file descriptors.
6414 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
6416 * Makefile.in (realclean): Delete m4.info*.
6417 Reported by Jim Meyering.
6419 * Makefile.in: Adjust and link with checks/Makefile.
6420 * checks/Makefile.in: New.
6421 * configure.in: Output checks/Makefile.
6423 * checks/get_them: Have the dnl header of each test more
6424 recognizable by next-error, also use a better message.
6426 1992-11-16 Jim Meyering <meyering@idefix>
6428 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
6429 And use that only if __GNUC__ since we're using it's GCC-specific
6430 semantics that tell the compiler the associated function doesn't
6433 * builtin.c (substitute): Don't use character as an array index.
6434 (dumpdef_cmp): Make formal arguments `const void *' to avoid
6435 warnings with gcc -W -Wall on systems with qsort prototype.
6436 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
6439 * eval.c (most functions): Add parentheses to assignments used
6440 as truth values go avoid warnings from gcc -Wall.
6442 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
6443 any functions that don't need external scope.
6445 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
6446 (many functions and arrays): Declare `const'.
6448 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
6450 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
6451 removing the declaration from m4.h. Also rename false to FALSE
6454 * lib/Makefile.in (Makefile): New goal.
6456 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
6457 so heavily loaded. It gets more easily overridable, calling make.
6458 Reported by Jim Meyering.
6460 * Makefile.in (dist): Get .fname from the current directory name,
6461 instead of from version.h. I need updating many files manually,
6462 when the version changes, version.h is just one of them.
6464 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
6466 * m4.h: Remove the tag `boolean' on the enum introducing typedef
6467 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
6468 Reported by Tom McConnell.
6470 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
6472 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
6473 39.cleardiv, which were describing missing or spurious newlines.
6474 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
6475 do not depend on machine word size, `/bin/false' implementation,
6476 or `wc' output format. `make check' is more dependable, now.
6478 * checks/check_them: Summarize the failed tests by listing their
6479 name, at end. If none, issue `All checks successful'. Output
6480 `Checking' instead of `Input file:'.
6482 * checks/get_them, checks/check_them: Reindented.
6484 * Makefile.in (dist): chmod a+r before making the tar file.
6486 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
6488 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
6490 * input.c (next_token): Reinitialize token_buttom just after using
6491 it as a watermark with obstack_free. Or else, a future token, big
6492 enough for triggering reallocation of the obstack chunk, could
6493 void the initialized value of token_buttom, later causing panic in
6494 obstack_free. Rename token_buttom to token_bottom everywhere.
6496 * m4.h: Before declaring errno, first include <errno.h> and
6497 ensure that it does not define errno.
6498 Reported by Richard Stallman.
6500 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
6502 * builtin.c: Define and use DECLARE macro for builtins.
6504 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
6505 argument, this is a common idiom for introducing long comments.
6507 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
6508 arguments. The last argument was silently ignored.
6510 * m4.c (cmd_error): Add a missing semicolon before va_end().
6512 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
6514 * Makefile.in: Now handle protoized sources. Define and use U.
6515 Compile and use ansi2knr with old compilers. Update DISTFILES.
6516 Add `aclocal.m4' to `configure' dependencies.
6517 * ansi2knr.c: New, from Ghostscript distribution.
6518 * configure.in: Define U through FP_PROTOTYPES for old compilers.
6519 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
6520 * aclocal.m4: New, provide FP_PROTOTYPES.
6521 * m4.h: Conditionnaly protoized through Args, save for varags.
6522 * builtin.c: Protoized. Then:
6523 Include <sys/types.h> if size_t is not defined, before "regex.h".
6524 (m4_ifelse): Fetch built-in name properly for diagnostic.
6525 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
6526 (m4_regexp): Add const to `msg' declaration.
6527 (m4_patsubst): Add const to `msg' declaration.
6528 * debug.c: Protoized, save for varargs.
6529 * eval.c: Protoized.
6530 * format.c: Protoized.
6531 * input.c: Protoized.
6532 * m4.c: Protoized, save for varargs. Then:
6533 (xfree): Accept void * instead of char *.
6534 (xmalloc): Return void * instead of char *.
6535 (xrealloc): Accept and return void * instead of char *.
6536 * macro.c: Protoized.
6537 * output.c: Protoized.
6538 * path.c: Protoized. Then cast some (char *) over xmalloc's.
6539 * symtab.c: Protoized.
6541 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
6543 * m4.texinfo: Remove directory from diagnostics in 30.include,
6544 51.eval, 56.errprint and 57.m4exit tests.
6546 * m4.h: Remove declarations for int or void system functions, they
6547 cause more conflicting trouble than they make good.
6549 * configure.in: Avoid configuration header file. Add some tests.
6550 * m4.h: Remove #include "config.h".
6551 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
6552 Then, rewritten for better compliance with GNU standards.
6554 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
6556 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
6557 because of a misplaced #endif.
6559 * Many *.[hc] files: Correct intra-line spacing here and there,
6560 according to GNU indent 1.6 advice.
6562 * configure.in: New, using Autoconf 1.2.
6563 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
6564 * Delete old configure.in, configure, etc/configure.in,
6565 etc/configure, lib/configure.in, lib/configure and config/*.
6566 Reported by Jason Merrill.
6568 * symtab.c (hash): Change (char) NULL to '\0'.
6569 Reported by Jason Merrill.
6571 * Delete .vers, etc/newdist.sh, etc/newvers.sh and
6572 etc/nextvers.sh. Release numbers will be edited `by hand'.
6573 * version.h: De-automatize, force value in.
6575 * m4.c: Changes in order to use a newer getopt.h.
6576 Reported by David MacKenzie.
6578 * checks/: New name for examples/.
6579 * checks/get_them: New location for etc/get_examples.
6580 * checks/check_them: New location for etc/check_examples.
6581 * Makefile.in, checks/get_them, checks/check_them: Adjust.
6582 * lib/vfprintf.c: New location for etc/vfprintf.c.
6583 * Delete empty etc/.
6584 * examples/: New name for test/.
6586 1992-03-10 François Pinard <pinard@iro.umontreal.ca>
6588 * Makefile.in (check): Add m4 as dependency.
6590 * m4.c: Accept --no-warnings instead of --no_warnings, and
6591 --no-gnu-extensions instead of --no_gnu_extensions. Make the
6592 usage message more informative.
6593 Reported by David MacKenzie.
6595 1992-03-09 François Pinard <pinard@iro.umontreal.ca>
6597 * etc/check_examples: New name for check_examples.sh.

6599 * Makefile.in, etc/Makefile.in: Use new names.
6601 * Makefile.in: Transmit $(CC) while making in lib.
6603 * Many *.[hc] files: GNU indent'ed, with further fine tuning of
6604 code disposition by hand.
6606 1992-03-08 François Pinard <pinard@iro.umontreal.ca>
6608 * m4.h: Delete definitions for abort() and exit().
6609 Reported by Richard Stallman.
6611 * config/hmake-unicos, config/s-unicos.h: New files.
6612 Reported by Hal Peterson.
6614 * eval.c (exp_term): Have N^0 return 1.
6615 Reported by Michael Fetterman.
6617 * eval.c, input.c, m4.h: Remove last comma in enums.
6618 Reported by Mike Lijewski.
6620 * Transfer of maintenance duties from René to François.
6622 1991-10-24 René Seindal <seindal@diku.dk>
6624 * Release 1.0. Many thanks to those, who provided me with bug
6625 reports and feedback.
6627 * Uses GNU configure, taken from the gdb distribution.
6629 * Uses GNU getopt(), with long option names.
6631 * The -Q/+quiet option is added, which suppresses warnings about
6632 missing or superflous arguments to built-in macros.
6634 * Added default options via the M4OPTS environment variable.
6636 * The built-in format can now be configured to use sprintf as
6637 the formatting engine, for systems without [efg]cvt(3).
6639 * GNU library code is moved to the ./lib subdirectory; other
6640 utility files are now in ./etc.
6642 * Several minor bugs have been fixed.
6644 1991-07-26 René Seindal <seindal@diku.dk>
6646 * Fixed various bugs. Release 0.99, manual 0.09. Many thanks to
6647 Francois Pinard and Roland H. Pesch for providing me with reports.
6649 * The builtins incr and decr are now implemented without use of
6652 * The builtin indir is added, to allow for indirect macro calls
6653 (allows use of "illegal" macro names).
6655 * The debugging and tracing facilities has been enhanced
6656 considerably. See the manual for details.
6658 * The -tMACRO option is added, marks MACRO for tracing as soon
6661 * Builtins are traced after renaming iff they were before.
6663 * Named files can now be undiverted.
6665 * The -Nnum option can be used to increase the number of
6666 divertions available.
6668 * Calling changecom without arguments now disables all comment
6671 * The function m4_patsubst() is now consistently declared
6674 * A bug in dnl is fixed.
6676 * A bug in the multi-character quoting code is fixed.
6678 * Several typos in the manual has been corrected. More probably
6681 * The m4.info file is now installed along with the program.

6706 * Implemented control over debugging output.
6708 * Implemented multi-character quotes.
6710 * Implemented multi-character comment delimiters.
6712 * Changed predefined macro "gnu" to "__gnu__".
6714 * Changed predefined macro "unix" to "__unix__", when the -G
6715 option is not used. With -G, "unix" is still defined.
6717 * Changed "shift", "$@" and "$*" to not insert spaces afters
