166 * Makefile.am (src_m4_DEPENDENCIES): Make dependency explicit.
167 (clean-local): Split into and depend upon...

179 Reported by Ralf Wildenhues.

511 * m4/output.c (m4_insert_file): Don't assume errno has a valid
512 value simply because fread returns zero. This fixes a
513 portability bug reported by Marion Hakanson in
514 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.

528 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
529 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
530 and libtoolize does a better job of ltdl importing now too, so
531 take advantage of that while updating the tree:
533 * acm4, config: Moved from here...
534 * ltdl/m4, ltdl/config: ...to here.
535 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
536 src/Makefile.am, tests/Makefile.am: Removed...
537 * Makefile.am: ...and migrated to here, with adjustments to
538 compensate for relative path differences.
539 * commit: Adjust relative paths.
540 * configure.ac: Adjust relative paths.
541 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
543 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
544 the meanwhile, CVS HEAD libtool is needed.
545 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
546 stricly new enough, we also need a patch.
547 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
548 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
549 (gl_MODULES): Don't list getopt and version-etc, as they don't
551 * bootstrap: After running gnulib-tool to import the listed
552 modules, fetch getopt and version-etc into src manually.
553 (ltdldir): Change to ltdl.
554 * src/main.c: Adjust for changes in version-etc API.
555 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
556 but works when the getopt module isn't to be included in the lib.
557 * README: Add note about patching autoconf and automake to
560 2005-05-02 Matt Kraai <kraai@debian.org> (tiny change)
562 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=84416
563 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
564 empty file rather than to a nonexistent file. This closes a
565 common security hole.
566 * modules/m4.c (m4_maketemp): Implement the above, by using
567 mkstemp rather than mktemp.
569 2005-05-01 Gary V. Vaughan <gary@gnu.org>
571 The FSF are moving offices today. Changed their contact address
572 in all files from `59 Temple Place, Suite 330, MA 02111-1307' to
573 `51 Franklin Street, Fifth Floor, MA 02110-1301'.
575 2005-03-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
577 * tests/Makefile (clean-local): Ignore testsuite cleanup
580 2005-03-11 Per Bothner <per@bothner.com> (tiny change)
582 * tests/Makefile (clean-local): Only run the testsuite cleanup
583 if the testsuite has been generated.
585 2005-02-11 Stepan Kasal <kasal@ucw.cz>
587 * TODO: slight clarification of the example of qindir usage.
589 2005-02-08 Gary V. Vaughan <gary@gnu.org>
591 * TODO: Add qindir requirement, and defn bug.
592 From Stepan Kasal <kasal@ucw.cz>
594 2005-02-08 Stepan Kasal <kasal@ucw.cz>
596 * TODO: Add ``execution stack'', fix a typo.
597 * doc/m4.texinfo: Typos.
599 2004-12-24 Eric Blake <ebb9@byu.net>
601 * configure.ac (INCLUDE_STDBOOL_H): Account for gnulib's move
602 to the gnu subdirectory.
603 * acm4/m4-error.m4 (INCLUDE_ERROR_H): Likewise.
604 * acm4/m4-obstack.m4 (INCLUDE_OBSTACK_H): Likewise.
605 * acm4/m4-regex.m4 (INCLUDE_REGEX_H): Likewise.
606 * m4/system_.h: Likewise, in non-configured includes.
608 2004-10-14 Noah Misch <noah@cs.caltech.edu>,
609 Gary V. Vaughan <gary@gnu.org>
611 * m4/m4.c (m4_context_field_table, m4_context_opt_bit_table):
612 Protect definitions from macro expansion under -DNDEBUG by
613 parenthesising the expanded function names.
614 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
615 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
616 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
617 (m4_is_syntax_macro_escaped): Similarly protect function
618 definitions from macro expansion under -DNDEBUG by #undefing the
619 matching macro names before each definition. Also, move all the
620 function definitions to the end of the file so that any
621 invocations in the rest of the file pick up the fast macro
623 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)
624 (m4_set_debug_file, m4_set_trace_messages)
625 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
626 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
627 (m4_set_max_debug_arg_length_opt): New fast macro versions of the
628 option setter functions.
630 2004-09-23 Gary V. Vaughan <gary@gnu.org>
632 * src/main.c: Include gnulib files from the correct directory.
634 * gnulib/*: Don't store any of the gnulib files in arch, as they
635 generate spurious changes.
636 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
637 gnulib macros now share our macro directory.
638 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
639 * bootstrap: Call gnulib-tool to import from the gnulib tree.
640 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
641 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
642 the gettext macros from autopoint that overwrite the gnulib-tool
643 imported versions. Import sources and Makefile.am into the `gnu'
644 directory. Changed all callers.
645 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
646 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
647 for imported modules.
648 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
649 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
650 hardcoding the gnulib macros they wrap.
652 2004-07-15 Gary V. Vaughan <gary@gnu.org>
654 Latest CVS libtool can preload modules in libraries, including
655 its own module loaders! Tweak m4 so that it doesn't try to treat
656 libltdl's module loaders as m4 modules when freezing and on exit:
658 * gnulib/acm4/*.m4: Don't store these files in arch since they
659 generate spurious changes.
660 * bootstrap: Simplify initial libtoolize call, since CVS
661 libtoolize is smarter these days.
662 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
664 * m4/module.h (m4__module_exit): Missing declaration.
665 * m4/m4private.h (m4__module_next): New function declaration.
666 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
667 encapsulation. Changed all callers.
668 (m4__module_interface): New function to verify m4 loadable module
670 (m4__module_init): Register the interface validator.
671 (m4__module_exit): Only close my own modules.
672 * modules/m4.c (unistd.h): Provide missing declaration.
673 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
674 (m4_expand_ranges): More missing declarations.
675 * modules/modtest.c (export_test): Ditto.
676 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
677 * src/main.c (main): Bump copyright year.
678 * tests/modules.at: Fix sed syntax error.
681 2004-06-17 Gary V. Vaughan <gary@gnu.org>
683 Tweaking to enable compilation with latest CVS libtool and
684 libltdl. We can't just dump the library files directly into the
685 m4 directory anymore now that libltdl is built from pieces itself:
687 * bootstrap: Rewritten to use latest libtoolize sanely, and to
688 set up libltdl subdirectory.
689 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
690 gnulib subdirectory's config.
691 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
692 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
694 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
695 configure.ac, so use AC_WITH_LTDL instead.
696 * Makefile.am (SUBDIRS): Add libltdl.
697 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
699 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
700 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
701 (libm4_la_LIBADD): Add LIBLTDL.
702 * m4/ltdl.c, m4/ltdl.h: Removed.
703 * m4/m4module.h: Include canonical ltdl.h.
706 2004-06-14 Gary V. Vaughan <gary@gnu.org>
708 * gnulib/import: Now updates makefile fragments, and configure.ac.
709 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
710 * gnulib/m4/Makefile.am: include it.
711 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
712 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
713 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
714 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
715 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
716 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,
717 gnulib/acm4/lib-ld.m4, gnulib/acm4/lib-prefix.m4,
718 gnulib/acm4/error.m4, gnulib/acm4/po.m4, gnulib/acm4/regex.m4,
719 gnulib/acm4/stdbool.m4, gnulib/acm4/stdint_h.m4,
720 gnulib/acm4/uintmax_t.m4, gnulib/acm4/ulonglong.m4,
721 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
722 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
723 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
725 * gnulib/m4/getopt_int.h: New source file from latest gnulib
727 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
728 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,
729 gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
730 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
731 Updated source files from latest gnulib.
733 2004-02-29 Gary V. Vaughan <gary@gnu.org>
735 * config/mailnotify: New file for mailing commit notifications,
736 imported from cvs-utils.
737 * commit: Updated from cvs-utils and tweaked for m4.
739 2003-12-01 Gary V. Vaughan <gary@gnu.org>
741 * config/mkstamp: Updated from CVS libtool.
742 * configure.ac: Generate a gnu coding standards compliant version
743 number, and use it for the banner.
744 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
745 mhen the TIMESTAMP changes in ChangeLog, but the file modification
746 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
747 contain the previous version number.
748 * src/main.c: Make --version output conform to the GNU standard.
750 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
751 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
752 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
753 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
754 time_la_SOURCES): ...so that these are defaulted correctly, and
755 can be removed from this file.
756 (AM_LDFLAGS): Add -module...
757 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
758 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
759 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
760 the individual settings can be removed.
761 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
762 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
763 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
764 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
765 time_la_LIBADD): ...so that these are picked up as a deplib of
766 libm4 and don't need to be set explicitly.
768 2003-11-18 Gary V. Vaughan <gary@gnu.org>
770 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
771 from the standard build. It is too fragile.
773 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
774 CVS libtool after merging m4 changes across to libtool.
776 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
777 * m4/path.c (search_path_add): Ditto.
779 2003-11-13 Gary V. Vaughan <gary@gnu.org>
781 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
782 libtool tags we don't use in configure. This reduces the size
783 of the script from over 1Mb to under 700Kb.
785 2003-11-13 Gary V. Vaughan <gary@gnu.org>
787 The import script was not written properly, and the last gnulib
788 import was incomplete. Fixed that problem, and reimport our
789 gnulib dependencies, which picks up the address calculation
790 overflow checks described by Paul below. Also tweak the clients
791 of the gnulib xalloc module not to use deprecated macros:
793 * gnulib/import: Recurse through module dependencies rather than
794 naively descending only one level.
795 * configure.ac: Add calls to gnulib's strnlen and extension module
797 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
799 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
800 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
801 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
802 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
804 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
805 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
806 place of `xcalloc (1, S)'.
807 * m4/m4.c (m4_create): Likewise.
808 * m4/m4private.h (m4_symbol_value_create): Likewise.
809 * m4/symtab.c (symtab_fetch): Likewise.
810 * m4/syntax.c (m4_syntax_create): Likewise.
811 * src/freeze.c (reload_frozen_state): Likewise.
812 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
814 * m4/symtab.c (m4_symtab_create): Likewise.
816 2003-11-13 Gary V. Vaughan <gary@gnu.org>
818 * tests/module.at: Comment typo.
820 2003-10-10 Gary V. Vaughan <gary@gnu.org>
822 * tests/modules.at (modules: importing): Apply some lateral
823 thinking, and use AT_CHECK to compare the output of a sed pass
824 over stderr against the canonical strerror string.
826 * tests/modules.at (modules: importing): Edit the generated stderr
827 output to canonicalize strerror output, before a comparison.
829 2003-10-10 Gary V. Vaughan <gary@gnu.org>
831 Tru64UNIX perl is sloppy with namespace pollution. This patch is
832 careful not to trip over the mess:
834 * modules/perl.c: Some builds of perl install headers that contain
835 `#define try __builtin_try'. Be sure to undefine that macro
836 before `m4/hash.h' gets included, which uses the `try' symbol.
837 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
838 `false' before including `stdbool.h'.
839 (DELETE): This symbol is not in m4's namespace, and is in any
840 case only used internally...
841 * m4/m4private.h (DELETE): ...so move it to here.
842 Reported by Martin MOKREJS <mmokrejs@natur.cuni.cz>
844 2003-10-08 Paul Eggert <eggert@twinsun.com>
846 Don't use XMALLOC and XCALLOC. Once we install the
847 corresponding patch into gnulib, this will fix some
848 address-calculation overflow bugs on hosts where calloc (A, B)
849 returns garbage when A*B overflows.
851 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
852 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
853 xmalloc, XCALLOC with xcalloc.
854 * m4/m4.c (m4_create): Likewise.
855 * m4/m4private.h (m4_symbol_value_create): Likewise.
856 * m4/output.c (m4_output_init): Likewise.
857 * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise.
858 * m4/syntax.c (remove_syntax_attribute): Likewise.
859 * src/freeze.c (reload_frozen_state): Likewise.
860 * src/main.c (main): Likewise.
862 2003-10-07 Gary V. Vaughan <gary@gnu.org>
864 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
865 gnulib/acm4 directories for aclocal m4 macros.
866 * gnulib/Makefile.am (EXTRA_DIST): Removed.
867 (MAINTAINERCLEANFILES): Add Makefile.in.
868 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
870 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
871 * gnulib/import: New file. Temporary script for updating gnulib
872 imported files, until gnulib-tool is working.
873 * gnulib/config/codeset.m4, gnulib/config/error.m4,

910 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
911 gnulib/acm4/xstrndup.m4: Reimported from CVS gnulib with

913 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/error.c,

919 gnulib with gnulib/import script.
920 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
921 guards ready for gnulib-tool to autoupdate on import.

927 acm4/stackovf.m4: ...to here, to separate aclocal macros from
928 configure time helper scripts.
929 * config/error.m4: Removed; superceded by gnulib/acm4/error.m4.
930 * m4/hash.c, m4/m4.c, m4/macro.c, m4/module.c, m4/output.c,
931 m4/path.c, m4/symtab.c, m4/syntax, m4/system_.h, modules/m4.c,
932 src/main.c, src/stackovf.c: s/xfree/free/g to comply with new
934 * src/main.c (version_etc_copyright): Only output the current
936 (version_etc): Call with new variadic API.
938 2003-09-16 Gary V. Vaughan <gary@gnu.org>
940 * gnulib/m4/version-etc.c, gnulib/m4/version-etc.h: Import
941 version-etc module from CVS gnulib.
942 * po/POTFILES.in: Add gnulib/m4/version-etc.c.
943 * src/Makefile.am: Build it.
944 * src/main.c: Use it.
946 * gnulib/m4/exit.h: Import exit module from CVS gnulib.
947 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
948 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
951 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
952 Gary V. Vaughan <gary@gnu.org>
954 * bootstrap: Separate options.
955 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
956 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
958 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
959 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
960 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
961 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
962 $(LTLIBINTL) for gettext support on cygwin.
963 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
964 have $(LTLIBINTL) from the preloaded module la files.
965 * README: Remove the warning about using --disable-nls on Windows
968 2003-09-15 Gary V. Vaughan <gary@gnu.org>
970 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
971 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
974 2003-09-12 Gary V. Vaughan <gary@gnu.org>
976 * doc/STYLE: Document the gnulib header naming conventions, and
978 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
979 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,
980 gnulib/m4/gettext.h, gnulib/m4/obstack.h, gnulib/m4/regex.h
982 * gnulib/m4/Makefile.am: Remove the rules to build these headers.
984 * gnulib/m4/strtol.c, gnulib/config/strtol.m4: Import strtol
985 module from CVS gnulib.
986 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
987 (gl_FUNC_STRTOL): In favour of the module macro.
989 2003-09-12 Gary V. Vaughan <gary@gnu.org>
991 Replace the getopt code with CVS gnulib getopt. The source files
992 detect whether they are in a glibc environment and preprocess away
993 all of the code if there is a system getopt, so we can compile
994 them into the m4 executable unconditionally:
996 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
997 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
998 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
1000 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
1002 * src/Makefile.am: Adjust.
1003 * src/main.c: Always include our shipped getopt.h.
1004 * po/POTFILES.in: Use new location of getopt.c.
1006 2003-09-12 Gary V. Vaughan <gary@gnu.org>
1008 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
1009 * config/Makefile.am: Removed. Automake 1.8 distributes the files
1010 in this directory automatically.
1011 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
1013 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
1015 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
1017 * modules/Makefile.am (pkglibexecdir): Set it here.
1018 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
1020 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
1021 Import regex module from CVS gnulib.
1022 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
1023 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
1024 do extra substitutions for Makefile.
1025 * configure.ac: Use it.
1026 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
1027 from regex_.h if necessary.
1028 * m4/system_.h: Include the correct version of regex.h.
1029 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
1031 * po/POTFILES.in: Use new location of regex.c.
1033 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
1034 realloc.c: automake distributes these files already.
1036 2003-09-12 Gary V. Vaughan <gary@gnu.org>
1038 Replace the xstrzdup code by importing the xstrndup module from
1039 CVS gnulib, along with its dependencies: strndup and strnlen:
1041 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
1042 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
1044 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
1045 gnulib/config/strndup.m4: Ditto wrt strndup.
1046 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
1048 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
1049 However, contrary to gnulib, we install xstrndup.h.
1050 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
1051 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
1052 is an artifact of the old m4 portability layer.
1053 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
1054 * m4/system_.h: Include xstrndup.h.
1055 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
1057 2003-09-11 Gary V. Vaughan <gary@gnu.org>
1059 Reimport the latest xalloc module from CVS gnulib, and adjust the
1060 m4 sources to take advantage of xalloc xfree. Also create a new
1061 macro DELETE with the same semantics as the old m4 XFREE macro,
1062 and carefully tweak callers:
1064 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
1066 * m4/utility.c (xfree): Removed. This function is now supplied by
1068 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
1069 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
1070 * m4/symtab.c (m4_symtab_create): Ditto.
1071 * m4/system_.h: Removed XFREE redefine.
1072 (DELETE): New macro with same functionality as the original m4
1073 XFREE macro, but based on xalloc.h now. Changed all callers.
1074 * src/main.c (main): Use XMALLOC macro.
1075 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
1077 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
1079 2003-09-10 Gary V. Vaughan <gary@gnu.org>
1081 Import the xalloc module from CVS gnulib, along with its
1082 dependencies: exitfail, malloc and realloc. We had different
1083 semantics for our XFREE and a function xfree() not supplied by
1084 gnulib, so also a bit of work to keep everything running
1087 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
1088 (gl_XALLOC): Use gnulib equivalents.
1089 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
1090 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
1091 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
1092 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
1094 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
1095 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
1096 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
1098 (pkgincdir): Removed. Use pkgincludedir instead.
1099 * m4/m4private.h (XFREE): xfree already checks for NULL.
1100 * m4/system_.h: Use xalloc module, and remove macros already
1101 supplied by xalloc.h.
1102 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
1103 moved the old definition from m4/xmalloc.c to here for now.
1105 2003-09-09 Gary V. Vaughan <gary@gnu.org>
1107 Import the error and progname modules from CVS gnulib. Our old
1108 error.c subsumed the functionality of both, so a little adjustment
1109 was required to accomodate the split in sources. Also added more
1110 wrapper macros to choose between a system installed error.h or our
1111 shipped gnulib error module:
1113 * m4/error.c, m4/error.h: Removed.
1114 * m4/Makefile.am: Adjust.
1115 (pkgincdir): Removed. Use pkgincludedir instead.
1116 * m4/module.h, src/main.c: Don't include `m4/error.h'.
1117 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
1119 * gnulib/m4/progname.c: Imported from CVS gnulib.
1120 * gnulib/m4/progname.h: Ditto.
1121 * src/main.c: Adjust to use progname module.
1122 * gnulib/m4/error.c: Imported from CVS gnulib.
1123 * gnulib/m4/error_.h: Ditto.
1124 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
1125 if appropriate, and link a local error.h if the system version is
1127 (libgnu_la_SOURCES) Add progname module sources.
1128 * gnulib/config/error.m4: Imported from CVS gnulib.
1129 * gnulib/config/strerror_r.m4: Ditto.
1130 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
1131 to have ERROR_H for Makefile substitutions and tell system.h
1132 whether the system error.h should be used, or a locally installed
1134 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
1136 2003-09-09 Gary V. Vaughan <gary@gnu.org>
1138 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
1139 s/gettext_.h/gettext.h/.
1141 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
1142 automake have been fixed.
1144 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
1145 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
1146 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
1147 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
1149 2003-09-09 Gary V. Vaughan <gary@gnu.org>
1151 The gnulib obstack module requires the gnulib gettext module for
1152 systems that do not have GNU gettext installed. Because we use
1153 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
1154 that directory incase it clashes with the system gettext.h. This
1155 delta uses gettext_.h and extra rules in the Makefile to make a
1156 link to gettext.h when needed:
1158 * Makefile.am (auxdir): Removed. No longer used.
1159 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
1160 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
1162 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
1163 Makefile based build.
1164 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
1165 of the macros are kept.
1166 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
1167 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
1168 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
1169 distributes these automatically.
1170 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
1171 warning from automake-1.7a.
1172 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
1173 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
1175 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
1176 wrt. m4_FUNC_OBSTACK.
1177 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
1178 wrt. m4_sys_STACKOVF.
1179 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
1180 wrt. _m4_LIB_GMP, m4_LIB_GMP.
1181 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
1182 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
1184 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
1185 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
1186 gettext.h link on deficient systems.
1187 (pkginc_HEADERS): Mention $(GETTEXT_H).
1188 (EXTRA_HEADERS): Mention gettext.h.
1189 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
1190 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
1191 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
1192 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
1193 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
1194 gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
1195 gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
1196 gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
1197 gnulib/config/po.m4, gnulib/config/progtest.m4,
1198 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
1199 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
1201 2003-09-05 Gary V. Vaughan <gary@gnu.org>
1203 We can't mirror the gnulib directory structure here, since we need
1204 to be able to eg. `#include <m4/obstack.h>' from our source files,
1205 which is much easier if the local obstack.h is created in a
1206 directory named m4. Rather than trying to symlink everything into
1207 the m4 directory, now we build a libtool convenience library from
1208 the sources we get from gnulib and link that with libm4.la:
1210 * gnulib/config/extensions.m4: Imported from CVS gnulib.
1211 * gnulib/config/unlocked-io.m4: Ditto.
1212 * gnulib/m4/unlocked-io.h: Ditto.
1213 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
1214 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
1215 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
1216 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
1217 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
1218 * m4/Makefile.am: Adjust.
1219 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
1220 macros we redistribute.
1221 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
1222 library among others.
1223 (GNULIB_SRCS, GNULIB_MACROS): Removed.
1224 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
1225 * config/m4-obstack.m4: Adjust.
1226 * po/POTFILES.in: Adjust.
1227 * configure.ac: Reformatting. Call newly imported gnulib macros.
1228 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
1229 bogus calls of `#include "m4.h"'.
1230 * Makefile.am: INCLUDES has been deprecated in favour of
1232 * m4/Makefile.am: Ditto.
1233 * modules/Makefile.am: Ditto.
1234 * src/Makefile.am: Ditto.
1236 2003-09-05 Gary V. Vaughan <gary@gnu.org>
1238 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
1240 2003-09-04 Gary V. Vaughan <gary@gnu.org>
1242 Migrate the obstack support into the gnulib directories for easy
1243 synchronisation with upstream files in gnulib:
1245 * config/gnu-obstack.m4: Moved from here...
1246 * config/m4-obstack.m4: ...to here.
1247 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
1248 * m4/obstack.c, m4/obstack_.h: Moved from here...
1249 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
1250 * po/POTFILES.in: Adjust.
1251 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
1252 * m4/Makefile.am: Add a whole new section to link the obstack
1253 sources from the gnulib tree if necessary.
1254 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
1256 * config/m4-obstack.m4: Rewrite as a wrapper for
1257 gnulib/m4/obstack.m4.
1259 2003-09-04 Gary V. Vaughan <gary@gnu.org>
1261 GNU M4 currently builds with a number of files adapted from
1262 upstream sources. Recently the gnulib project on savannah.gnu.org
1263 has pulled together a great many of these externally maintained
1264 files. This delta is the beginnings of isolating those files
1265 maintained in gnulib to make it easy to synchronise M4 with the
1266 upstream files prior to releases.
1268 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
1270 (SUBDIRS): Added new gnulib subdirectory.
1271 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
1272 * config/stdbool.m4: Moved from here...
1273 * gnulib/m4/stdbool.m4: ...to here.
1274 * m4/stdbool_.h: Moved from here...
1275 * gnulib/lib/stdbool_.h: ...to here.
1276 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
1278 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
1279 code to work with new stdbool_.h location.
1280 (gnulib_srcdir): New.
1282 2003-09-04 Gary V. Vaughan <gary@gnu.org>
1284 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
1285 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
1287 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
1288 (EXTRA_DIST): Use it.
1290 * bootstrap: CVS autoreconf leaves file droppings. Remove
1291 aclocal.m4t incase autoreconf doesn't.
1293 2003-08-29 Gary V. Vaughan <gary@gnu.org>
1295 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
1296 the other gnulib imports, renamed to m4/obstack_.h.
1297 * m4/obstack.c: Updated from CVS gnulib.
1298 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
1299 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
1300 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
1301 about vpath already, and $top_srcdir upsets CVS Automake, so the
1302 $top_srcdir reference was removed.
1304 * m4/system-h.in: For consistency with the gnulib imports, renamed
1306 * m4/Makefile (EXTRA_HEADERS): Adjust.
1307 * configure.ac (AC_CONFIG_FILES): Adjust.
1309 * m4/stdbool_.h: New file from gnulib for systems without their
1311 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
1312 * config/stdbool.m4: New file. Macros from gnulib for same.
1313 * configure.ac: Use it.
1315 2003-08-27 Gary V. Vaughan <gary@gnu.org>
1317 * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'`

1364 * src/main.c: Ditto.
1365 * src/stackovf.c: Ditto.
1367 * config/gmp.m4 (M4_AC_LIB_GMP): Use AC_INCLUDES_DEFAULT:
1368 ac_default_headers is an autoconf internal variable.
1369 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
1370 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
1372 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
1373 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
1376 2003-08-15 Gary V. Vaughan <gary@gnu.org>
1378 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
1380 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
1381 possible or faking one with a typedef. Changed all callers.
1383 2003-08-15 Gary V. Vaughan <gary@gnu.org>
1385 Still cleaning up the users' module API, by taking out the stuff
1386 that isn't used by any existing modules, and moving specialised
1387 functions out of libm4 and into the module they are used by.
1389 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
1390 * m4/utility.c (m4_skip_space): ...to here the home of its only
1391 use, made static and renamed to `skip_space'. Changed all
1393 * m4/m4module.h (m4_expand_ranges): Removed prototype.
1394 * m4/utility.c (m4_expand_ranges): Moved definition from here...
1395 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
1397 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
1399 * modules/gnu.c (builtin_syntax): Import and use in this
1400 builtin implementation.
1401 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
1403 * m4/macro.c (trace_flush): Except here where the macro is now
1405 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
1406 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
1408 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
1409 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
1411 2003-08-14 Gary V. Vaughan <gary@gnu.org>
1413 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
1414 compiler based AC_CHECK_HEADER that was introduced in
1416 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
1417 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
1418 * configure.ac: Use renamed M4_AC_LIB_GMP.
1420 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
1421 macro that requires arguments! This stops the shell's bad
1422 substitution error at configure time.
1424 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
1425 variables to the testsuite shell. Set the value of USE_GMP so
1426 that the gmp test will run!
1427 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
1429 2003-08-11 Gary V. Vaughan <gary@gnu.org>
1431 Libltdl already has an excellent mechanism for accessing C symbols
1432 in modules. Lets use that! Remove all the exporting cruft and
1433 just use lt_dlsym in conjunction with a few conventions to
1434 simplify module writers' jobs. Also removed the table address
1435 caching code and otherwise simplified the module loader quite a
1436 bit. To access exported symbols in other modules, first the
1437 exporting module must name the symbols <modname>_LTX_<symname>,
1438 and the importing module must define a function type called
1439 <symname>_func. The importer then adds
1440 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
1441 that wishes to call out to the exported functions. Care must be
1442 taken that <symname> is non-NULL in the importing module incase
1443 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
1444 definition was in the importers source. Study
1445 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
1446 m4_module_import will attempt to automatically load a module
1447 required for symbol access if it is not loaded already.
1449 * TODO: Removed the items fixed in this delta.
1450 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
1452 * m4/ltdl.h (lt_dlhandle_find): Declare it.
1453 * m4/module.c (m4_module_unload): Use it.
1454 * src/freeze.c (reload_frozen_state): Ditto.
1455 * m4/m4module.h (m4_export): Deleted. Removed all references.
1456 (M4_MODULE_IMPORT): New user convenience macro for importing
1457 arbitrary symbols from other modules.
1458 * m4/module.c (m4_module_import): New function to service
1459 M4_MODULE_IMPORT macro.
1460 (module_data): Removed. Looking up the tables on demand with
1461 lt_dlsym, rather than caching their addresses here simplifies the
1463 (m4_get_module_builtin_table, m4_get_module_macro_table):
1464 Removed. Changed all callers.
1465 (set_module_macro_table, set_module_builtin_table): Renamed to
1466 install_macro_table and install_builtin_table respectively, and
1467 simplified now that the cache is no more.
1468 * modules/gnu.c (builtin_symbols): Use this new mechanism to
1469 import m4_dump_symbols from the m4 module.
1470 (builtin_esyscmd): Likewise for m4_set_sysval and
1472 * modules/m4.c (m4_export_table): Removed. Functions are
1473 addressed with the new mechanism which doesn't need this.
1474 (m4_set_sysval): New exported accessor function to prevent
1475 problems with variable access on inferior architectures.
1476 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
1477 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
1478 that we can have some type safety.
1479 * modules/modtest.c (export_test): C level exported function for
1480 testing the new import mechanism.
1481 * modules/import.c: New file for the import end of the test.
1482 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
1483 * tests/modules.at: New test cases for intermodule symbol
1486 2003-08-07 Gary V. Vaughan <gary@gnu.org>
1488 * m4/m4module.c (m4_string): Moved from here...
1489 * m4/m4private.c (m4_string): ...to here.
1491 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
1493 2003-07-29 Gary V. Vaughan <gary@gnu.org>
1495 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
1496 already available to module writers through
1497 m4_{get,set}_nesting_limit_opt(), so moved from here...
1498 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
1499 (m4_create): Use it.
1501 2003-07-28 Gary V. Vaughan <gary@gnu.org>
1503 Aside from auditing path.c for m4module.h api obfuscation, this
1504 delta introduces the concept of private struct members in opaque
1505 data types to GNU m4: See the STYLE file for details.
1507 * TODO: Remind ourselves that a rewrite of path.c is needed.
1508 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
1510 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
1511 here and renamed. These type definitions are for internal api use
1512 only. Changed all callers.
1513 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
1515 * m4/path.c (search_path_env_init, search_path_add): ...to here
1516 and renamed. These calls were never used outside this file.
1517 Changed all callers.
1518 (dirpath): Moved functionality of this static declaration...
1519 * m4/m4private.h (struct m4): ...to this new internal only
1520 search_path field. Changed all callers.
1521 (m4__get_search_path): Added new internal api accessor.
1522 * m4/path.c (m4_search_path_info_new): Removed. Not used.
1523 (m4_include_init): Removed...
1524 * m4/m4.c (m4_create): ...because the new m4 field is now
1526 (m4_delete): Recycle search_path memory.
1527 * src/main.c (main): Don't call m4_include_init now that it's
1529 * doc/STYLE: Document convention for private fields in opaque
1532 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1534 Sometimes exporting the address of a symbol from a module isn't
1535 enough for other modules to call that symbol correctly. If
1536 custom data types are used for function parameters, they need to
1537 be known to the caller. This change introduces the concept of
1538 $(prefix)/include/modules/$(modulename).h to declare those
1539 structures. Also we move m4_dump_symbols from libm4 to the m4
1540 module to show this concept in action.
1542 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
1543 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
1544 exporting data structures from modules/m4.c.
1545 * modules/m4.c, modules/gnu.c: Include it.
1546 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
1547 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
1549 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
1551 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
1552 ...to here, with slight renaming.
1553 (m4_export_table): Prototype and add m4_dump_symbols.
1554 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
1555 definition of m4_dump_symbols.
1556 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
1557 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
1559 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1561 Create an export table in modules/m4.c in readiness for beefing up
1562 the module loader to track module exports and imports.
1564 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
1565 * m4/debug.c (m4_debug_flush_files): Moved...
1566 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
1567 * modules/gnu.c (builtin_esysval): Use it.
1568 * m4/m4module.h (m4_export): New type for declaring module symbols
1570 * modules/m4.c (m4_export_table): List symbols exported from this
1571 module for use by other modules.
1573 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1575 An experiment: There is loads of code in libm4 which should be in
1576 the m4 module, but is also used by another module. Just because
1577 some linkers won't cope with calls across dynamic runtime loaded
1578 objects I initially left the code in libm4. It will tidy the
1579 module api immensely if this code moves to the right place, I just
1580 need to remember to invent a suitable calling mechanism at some
1581 point. For now, only modules that are statically linked and
1582 preloaded will get this treatment, so the only platforms that will
1583 break are those that require all symbols to be resolved at link
1586 * TODO: Reminder that what I am doing could reduce portability
1587 unless I do something more robust later.
1588 * m4/m4module.h (m4_sysval): No longer exported from libm4.
1589 * m4/utility.c (m4_sysval): No longer declared in libm4.
1590 * modules/Makefile.am: Reformatting.
1591 * modules/m4.c (m4_sysval): Declare it at place of use.
1592 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
1594 2003-07-23 Gary V. Vaughan <gary@gnu.org>
1596 * m4/m4module.h: Reformatting and rearranging lines a bit.
1597 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
1599 (m4_call_macro, m4_expand_input): Renamed...
1600 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
1602 (m4_expansion_level, m4_process_macro): Moved...
1603 * m4/macro.c (expansion_level, process_macro): ...to here, and
1606 * m4/m4module.h (program_name): Not used by modules at all, so
1608 * src/main.c (program_name): ...to here.
1609 (print_program_name): Renamed...
1610 (print_program_name_CB): ...to conform to the STYLE guide.
1612 2003-07-23 Gary V. Vaughan <gary@gnu.org>
1614 More refactoring of the m4module.h API. Replace #defines with an
1615 enum, and move non-public functions out of the public API.
1617 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
1619 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
1620 * m4/debug.c (m4_debug, trace): Moved...
1621 * m4/m4private.h (struct m4): ...to fields of this struct.
1622 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
1624 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
1625 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
1626 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
1627 * m4/m4module.h (m4_context_field_table): Add entries for new
1628 debug_file and trace_messages fields.
1629 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
1630 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
1631 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
1632 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
1633 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
1634 (m4_is_debug_bit): New macro to simplfy checks against the debug
1636 (m4_trace_format, m4_trace_header, m4_trace_flush)
1637 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
1639 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
1640 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
1641 * m4/macro.c (trace_format, trace_header, trace_flush)
1642 (trace_prepre, trace_pre, trace_post): ...to these newly static
1643 functions, since they are only ever used from this file. Changed
1646 2003-07-17 Gary V. Vaughan <gary@gnu.org>
1648 Change the macros for checking syntax so that matching against
1649 multiple possible syntax classes can be done with a single
1650 comparison some of the time. The various classes are now bits of
1651 an int that can be checked with bitwise logic operators.
1653 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
1654 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
1655 (M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)
1656 (M4_SYNTAX_ASSIGN, M4_SYNTAX_ALPHA, M4_SYNTAX_NUM)
1657 (M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)
1658 (M4_SYNTAX_ECOMM): Replaced #defines with an enum.
1659 (M4_SYNTAX_ALNUM): Removed. Changed all callers.
1660 (M4_IS_IGNORE, M4_IS_OTHER, M4_IS_SPACE, M4_IS_OPEN, M4_IS_CLOSE)
1661 (M4_IS_COMMA, M4_IS_DOLLAR, M4_IS_ACTIVE, M4_IS_ESCAPE)
1662 (M4_IS_ASSIGN, M4_IS_ALPHA, M4_IS_NUM, M4_IS_LQUOTE, M4_IS_RQUOTE)
1663 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
1664 Replace all calls with invocations of these...
1665 (m4_is_syntax, m4_has_syntax): ...New macros.
1666 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
1667 is no longer required with new macros. Changed all callers.
1669 2003-07-15 Gary V. Vaughan <gary@gnu.org>
1671 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
1672 values are returned as part of the internal interface, so they
1674 * m4/private.h: ...to here.
1675 * m4/macro.c (expand_token): Check for out of range
1676 m4_peek_input() results before looking up in the syntax table.
1677 (collect_arguments): Ditto.
1679 * NEWS: Note `$' syntax class.
1681 2003-07-08 Paul Eggert <eggert@twinsun.com> and
1682 Gary V. Vaughan <gary@gnu.org>
1684 Conform to POSIX if the POSIXLY_CORRECT environment is set.
1685 --traditional `define' now smashes all the definitions.
1687 * NEWS: Explain this.
1688 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
1689 (Extensions): Explain that extensions that are incompatible with
1690 POSIX are disabled if POSIXLY_CORRECT is set.
1691 (Incompatibilities): Remove.
1692 (Define, Other Incompat): Explain difference
1693 between GNU and POSIX behavior of define, pushdef, popdef.
1694 * m4/m4.c (m4_get_posixly_correct_opt): New undef.
1695 * m4/m4module.h (m4_context_opt_bit_table): Add POSIXLY_CORRECT entry.
1696 * m4/m4private.h (M4_OPT_POSIXLY_CORRECT_BIT): New macro.

1703 (builtin_defn)): Allow any number of arguments.
1704 (builtin_undivert): Do not allow nonnumeric arguments
1706 * src/main.c (main): Set posixly-correct behavior if either
1707 POSIXLY_CORRECT is set, or if -G is given.
1708 * tests/builtins.at: New test for smashed definitions.
1710 2003-06-27 Gary V. Vaughan <gary@gnu.org>
1712 * doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
1713 * m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
1714 not to slow the parser down.
1715 (M4__IS_STRING): New macro to test string syntax class membership.
1716 * m4/syntax.c: Adjust docucomment.
1717 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
1718 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
1719 * m4/input.c (init_builtin_token): Comment typo.
1720 (m4__next_token): Comment typo.
1721 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
1722 by using the new M4__IS_STRING macro.
1723 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
1724 variable references in macro expansions.
1726 * doc/m4.texinfo (Eregexp and Regexp): Typo.
1727 (Epatsubst and Patsubst): Typo.
1730 2003-06-26 Gary V. Vaughan <gary@gnu.org>
1732 Move the global variables that pertain to syntax to a new `struct
1733 m4_syntax_table', and then add one of these to `struct m4'. The
1734 ripple effect through the code to both change formerly global
1735 references, and make sure a suitable context is available in
1736 lexical scope is disproportionately large compared to the size of
1737 the change proper. This change is a large part of decoupling
1738 syntax.c from the rest of the code that uses it.
1740 * m4/m4private.h (struct m4): Add a syntax field.
1741 * m4/m4.c (m4_create): Initialise it,
1742 (m4_delete): Recycle it.
1743 (m4_get_symtab): Remove hand coded version...
1744 (m4_get_symbol_table): ...and generate this with cpp. Changed all
1746 * m4/m4module.h (m4_context_field_table): Add an extra field so we
1747 can generate m4_get_symbol_table. Add a new row for
1748 m4_get_syntax_table.
1749 (M4SYNTAX): Syntactic sugar for module writers.
1750 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
1751 (m4_syntax_table): New home for syntax related formerly global
1753 * m4/m4private.h (struct m4_syntax_table): Define it.
1754 * m4/input.c (m4_input_init): Initialisation of these formerly
1755 global variables moved...
1756 * m4/syntax.c (m4_syntax_create): ...to here.
1757 * m4/input.c (m4_input_exit): And similarly, recycling of the
1758 memory used by those values moved...
1759 * m4/syntax.c (m4_syntax_delete): ...to here.
1760 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
1761 Moved to m4/m4private.h.
1762 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
1763 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
1764 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
1765 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
1766 objects. Changed all callers that used to directly access the
1768 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
1769 Removed and incorporated into m4_syntax_table structure.
1770 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
1771 * m4/syntax.c (m4_set_syntax): Now returns an error status,
1772 instead of requiring a `struct m4' to generate its own errors.
1773 Changed all callers.
1774 * src/main.c (main): Now that the syntax table is initialised as
1775 part of m4_create, we have to manually wipe the syntax entries if
1776 we are about to read a frozen file.
1778 2003-06-26 Gary V. Vaughan <gary@gnu.org>
1780 * doc/STYLE: Added notes on callback naming schemes.
1782 * m4/module.c (m4_set_module_macro_table)
1783 (m4_set_module_builtin_table): Declarations weren't changed when
1784 definitions were renamed on 2003-06-19.
1786 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
1787 neither used nor particularly appropriate since it exposes the
1788 internal workings of the hash module. I haven't yet decided
1789 whether to remove it entirely.
1791 2003-06-20 Gary V. Vaughan <gary@gnu.org>
1793 Two related changes, and a huge knockon effect throughout the
1794 source: Moved the option variables out of global space and into
1795 `struct m4'; made `m4_symtab' a real datatype, so that its api
1796 is not marred passing `struct m4' around just so it can decide
1797 whether to keep traced symbol names or not. Added setters and
1798 getters for the formerly global option variables, and obviously
1799 changed a vast number of functions to take a `struct m4' and use
1800 the getter funcs to find option values.
1802 * m4/utility.c (interactive, sync_output, debug_level)
1803 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
1804 (max_debug_argument_length, warning_status, nesting_limit)
1805 (discard_comments): Removed.
1806 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
1807 (debug_level, max_debug_argument_length, prefix_all_builtins)
1808 (suppress_warnings, discard_comments, interactive, sync_output):
1809 Removed from here...
1810 * m4/m4private.h (struct m4): ...and equivalent fields added to
1812 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
1813 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
1814 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
1815 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
1816 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
1817 macros for the new fields.
1818 * m4/m4module.h (m4_context_field_table)
1819 (m4_context_opt_bit_table): Helper macros used to generate
1820 prototypes, setters and getters for new option fields
1822 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
1823 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
1824 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
1825 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
1826 (m4_get_interactive_opt, m4_get_sync_output_opt)
1827 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
1828 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
1829 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
1830 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
1831 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
1832 setter and getter functions generated by cpp from
1833 m4_context_field_table and m4_context_opt_bit_table, exported as
1834 part of the module api. Changed all callers.
1835 * m4/symtab (struct m4_symtab): Used as the concrete type for
1837 (m4_symtab_create): Allocate and initialise a new struct.
1838 (m4_symtab_apply): New function that works like m4_hash_apply, but
1839 with different callbacks specific to symbol tables. Changed all
1841 (symbol_destroy, arg_destroy, arg_copy): Renamed
1842 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
1843 they have unused parameters for a reason!
1844 (dump_symbol_CB): New callback to dump the contents of a single
1846 (symtob_dump): Rewritten in terms of dump_symbol_CB.
1847 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
1848 Changed all callers.
1849 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
1850 of the contained `m4_symtab' at the `no_gnu_extensions' field.
1851 Although I'm not convinced these semantics are correct, they are
1852 at least consistent with how things were before this delta. Also
1853 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
1855 2003-06-19 Gary V. Vaughan <gary@gnu.org>
1857 Tie down the interface to libm4 some more. Make more structures
1858 opaque to modules by moving them to m4private.h, and writing
1859 setters and getters. To win back the speed penalty for doing this
1860 also wrote macroized versions that do know about structure layout
1861 in m4private.h and #include that file into modules when NDEBUG is
1862 defined at compile time. There are still some accessor macros in
1863 m4private.h that need to go, but that is not necessary to clean
1866 * m4/m4module.h (m4_symbol_type): Moved...
1867 * m4/m4private.h (m4__symbol_type): ...to here.
1868 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
1869 (m4_set_symbol_traced, m4_set_symbol_name_traced)
1870 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
1871 (m4_get_symbol_func, m4_symbol_value_create)
1872 (m4_symbol_value_delete, m4_set_symbol_value_text)
1873 (m4_set_symbol_value_func): New exported api to symbols.
1874 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
1875 and m4_is_symbol_value_func.
1876 * m4/m4module.h: Prototype these guys.
1877 * m4/module.c (m4_set_module_macro_table)
1878 (m4_set_module_builtin_table): Make these static, there is no
1879 reason to pollute the api with them.
1880 * m4/m4private.h: Reformatting.
1881 (m4_get_symtab): Only define when NDEBUG is defined.
1882 (m4_get_symbol_value, m4_get_symbol_traced)
1883 (m4_set_symbol_traced, m4_set_symbol_name_traced)
1884 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
1885 (m4_get_symbol_func, m4_symbol_value_create)
1886 (m4_symbol_value_delete, m4_set_symbol_value_text)
1887 (m4_set_symbol_value_func): Macro implementations of the new
1888 functions when NDEBUG is defined.
1889 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
1890 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
1891 Superceded by the above. All callers changed.
1892 (M4ARG): Removed. This is no longer different to the
1893 m4/m4module.h definition.
1894 * modules/gnu.c, modules/m4.c: Only include m4private.h when
1895 NDEBUG is defined. That way we exercise the same (albeit slower)
1896 api that external modules must use.
1898 2003-06-18 Gary V. Vaughan <gary@gnu.org>
1900 Renamed some of the types and their accessors to make more sense.
1901 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
1902 has a stack of SYMBOL_VALUEs.
1904 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
1905 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
1906 m4_get_symbol_value_type, m4_get_symbol_value_text,
1907 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
1908 Changed all callers.
1909 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
1910 (m4_get_token_type): Renamed
1911 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
1912 to the internal api.
1913 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
1915 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
1916 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
1917 (m4__token_type): Moved here from m4module.h.
1918 (m4__next_token): Renamed from m4_next_token.
1919 * m4/symtab.c: Removed some of the parameterised macro support
1920 functions for modularisation later.
1921 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
1922 m4_hash_dup to perform a true deep copy of the SRC.
1923 (arg_copy): Callback for m4_symbol_value_copy.
1924 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
1925 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
1926 m4_get_symbol_value_func. Changed all callers.
1928 2003-06-18 Gary V. Vaughan <gary@gnu.org>
1930 Tidy up style of hash.[ch] in accordance with doc/STYLE.
1932 * m4/hash.c: Internal symbol renaming and formatting.
1933 (m4_hash_dup): New function to facilitate deep copies of hash
1935 (m4_hash_apply_func): Returns a void* now, which is a richer type
1936 for returning exceptions (NULL means keep going).
1937 (m4_hash_apply): Ditto.
1938 * m4/hash.h: Declare exported symbols with an explicit extern.
1941 2003-06-17 Gary V. Vaughan <gary@gnu.org>
1943 Still refactoring furiously. This delta represents a change in
1944 semantics to symtab.c. Instead of building temporary m4_tokens
1945 in the caller, and copying fields in the methods, we now create
1946 the actual m4_token for hashing in the caller so the methods just
1947 slot them in directly. Also, this means that we don't lookup a
1948 symbol and get back an allocated but VOID token to copy fields
1949 into, we create the token we want to push and pass that to
1950 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
1951 a few other small changes to stop knowledge of the implementation
1952 of symtab.c leaking out into other files.
1954 * m4/macro.c (expand_argument): Comment typo corrected.
1955 * m4/symtab.c (symtab_fetch): New function to fetch the address of
1957 (m4_symbol_pushdef): Take an extra value parameter and use this
1958 directly as the new top of the value stack. All callers changed
1959 to build a token and pass responsibility for memory in, rather
1960 than copying as we used to.
1961 (m4_symbol_define): Also use the new value parameter directly as a
1962 replacement for the top of the value stack. All callers changed
1963 to build a token as above.
1964 (m4_set_symbol_traced): New function to set the traced bit on the
1965 named symbol, creating it if necessary.
1966 (symbol_popval): The guts of the old m4_symbol_popdef.
1967 (m4_symbol_popdef): Use it.
1968 * m4/builtin.c (m4_symbol_set_token): Removed,
1969 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
1971 * m4/module.c (m4_set_module_builtin_table)
1972 (m4_set_module_macro_table): ...with these more orthogonal
1974 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
1975 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
1977 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
1978 (m4_arg_signature_parse): Moved...
1979 * m4/symtab.c: ...to here.
1980 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
1981 screw something up. Moved...
1982 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
1983 actually does a proper deep copy of source to dest.
1985 2003-06-16 Gary V. Vaughan <gary@gnu.org>
1987 Further refactoring to stabilise the module API. Renaming some
1988 functions for orthogonality, and judicious definition migration to
1989 move things out of the set of exported symbols.
1991 * doc/STYLE: New file. Notes on coding style.
1992 * m4/m4module.c: Updated bitrotted docucomment at the top of the
1994 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
1995 m4_get_module_name, m4_get_module_builtin_table,
1996 m4_get_module_macro_table which are verb phrases. Changed all
1998 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
2000 * m4/module.c (m4_set_module_builtin_table)
2001 (m4_set_module_macro_table): ...here, and renamed. Changed all
2003 * m4/m4module.c (m4_module_data): This...
2004 * m4/m4private.c (struct m4_module_data): ...and this...
2005 * m4/module.c (module_data) ...consolidated here and no longer
2006 exported. Changed all callers.
2008 2003-06-16 Gary V. Vaughan <gary@gnu.org>
2010 Begin work on lifting the curse of the global variables. To start
2011 with create a `struct m4' context container, and replace
2012 `m4__symtab' with `context->symtab' throughout. This means
2013 initialising a context container in main, and adjusting many
2014 functions between main and the module entry points so that the
2015 container gets passed through. It would have been nice to
2016 defer this until after 1.5, but it has a major effect on the
2017 user's module writing ABI, so it needs to be addressed now - at
2018 least in the areas that impact the ABI. An interrelated change
2019 in the symtab API removes the dependency on a global symbol table,
2020 and instead focuses on a passed table (from the context
2023 * TODO: Reminders for finishing context functionality.
2024 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
2025 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
2026 global variables and eventually allow m4 to be reentrant.
2027 * m4/m4private.h (m4): Define the new structure here...
2028 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
2029 don't carry the overhead of a function call.
2030 * m4/m4module.h: Prototype extern functions from m4/m4.c.
2031 (m4): Declare type for new struct m4 objects.
2032 (M4SYMTAB): User macro to ease finding the symbol table for the
2033 current context for module developers.
2034 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
2036 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
2037 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
2038 (m4_call_macro, m4_dump_symbols, m4_expand_input)
2039 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
2040 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
2041 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
2042 m4* context parameter. Changed definitions and all callers.
2043 (m4_symtab): Alias for m4_hash to decouple the
2044 m4_symtab api from m4_hash.
2045 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
2047 (m4_symtab_create): New function to return an initialised
2049 (m4_symtab_delete): New function to delete an m4_symtab's memory.
2050 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
2051 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
2052 instead of simply using the global m4__symtab. Changed
2053 definitions and all callers.
2054 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
2055 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
2056 * src/main.c (main): Create a context and use that instead of the
2057 former global m4__symtab.
2059 2003-06-13 Gary V. Vaughan <gary@gnu.org>
2061 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
2062 to the callback. Callbacks should not need to hardcode the
2063 hashtable they are working from, nor should we have to waste the
2064 userdata parameter to pass the table in.
2065 * m4/hash.h (m4_hash_apply_func): Require the initial table
2067 * m4/symtab.c (symtab_destroy): Use the passed table instead
2068 of hardcoding m4__symtab.
2069 (m4_symbol_popdef): Don't use the userdata parameter to pass the
2070 table to arg_destroy.
2071 (arg_destroy): Use the hash parameter, ignore userdata.
2072 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
2074 (traceon, traceoff): Call set_trace with the extra initial
2077 2003-06-13 Gary V. Vaughan <gary@gnu.org>
2079 More refactoring to stabilise the module api, this time for
2080 symtab.c. Additionally, start to pay attention to function names
2081 that don't contain a verb like they should.
2083 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
2084 wrapper for m4_hash_apply to decouple the symtab module from the
2086 (m4_symbol_builtin, m4_symbol_macro): Renamed to
2087 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
2089 (m4_symbol_delete): Create a macro version to save a function
2091 (m4_token_t, m4_data_t): These violate the POSIX reserved
2092 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
2094 (m4_token_type): Renamed to m4_token_get_type.
2095 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
2096 (m4_symtab_exit): Removed from the exported module
2098 * m4/m4private.h (m4__symtab, m4__symtab_init)
2099 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
2100 renamed and added to the internal api. Changed all callers.
2101 (m4_symtab_apply): A faster macro version of the function for
2102 users of the internal api.
2103 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
2104 symbol_destroy and arg_destroy.
2105 (symtab_debug): Added a prototype.
2106 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
2107 so that callers in this file get the faster macro versions from
2110 2003-06-12 Gary V. Vaughan <gary@gnu.org>
2112 Refactoring modules to rationalise the API into an external
2113 documented (eventually!) API for use by modules in the `m4_'
2114 namespace declared in m4/m4module.h, an internal API between the
2115 source files we ship (including our shipped modules) in the `m4__'
2116 namespace declared in m4/m4private.h and making the rest as
2117 cohesive as possible with liberal use of the `static' keyword.
2118 This change represents an audit to m4/module.c along these
2121 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
2122 Removed. No longer used.
2123 (m4_module_close): Removed prototypes.
2124 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
2125 from the exported module api...
2126 * m4/m4private.h (m4__module_init, m4__module_open)
2127 (m4__module_exit): ...and renamed and added to the internal api.
2128 Changed all callers.
2129 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
2130 Centralised definitions after renaming...
2131 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
2132 (M4_FINISH_SYMBOL): ...and removing from here.
2133 (m4_module_dlerror, m4_module_remove, m4_module_close)
2134 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
2135 module_remove, module_close and caller_id.
2136 (MODULE_SELF_NAME): New macro to make reporting self errors
2138 (m4_module_load, module_close, module_remove): Use it.
2139 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
2141 * src/main.c (main): Use it.
2143 2003-06-12 Gary V. Vaughan <gary@gnu.org>
2145 * README: Remove references to --enable-changeword, which has been
2146 removed from the code.
2148 2003-06-11 Gary V. Vaughan <gary@gnu.org>
2150 Getting rid of the annoying bug with configure --enable-debug,
2151 which spewed -e: command not found errors. This was an interaction
2152 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
2153 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
2154 branch-1-5) to get the full fix.
2156 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
2157 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
2158 and then use the probed value of $SED.
2159 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
2160 this, it messes up the AC_REQUIRE stack.
2162 2003-06-10 Gary V. Vaughan <gary@gnu.org>
2164 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
2165 the destroy callback.
2166 (m4_arg_destroy): Use the hash address to free the hash node key
2169 2003-06-06 Gary V. Vaughan <gary@gnu.org>
2171 First cut at formal parameters in macros.
2173 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
2174 * m4/xstrzdup.c: New file.
2175 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
2176 associative array of parameter names to details.
2177 (m4_symbol_token): Capture macro names with parameter lists.
2178 (m4_arg_signature_parse): And build an associative array to hang
2179 from the symbol structure to map names to details.
2180 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
2181 m4_hash_resize idiom. Now that we potentially add a little hash
2182 table to many of the entries in the symbol table, added an extra
2183 arg to set the initial size. Changed all callers.
2184 (m4_hash_apply): New function that is basically a generalised
2186 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
2187 all callers to call m4_hash_apply instead.
2188 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
2189 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
2190 m4_arg_signature association that might be attached to the symbol,
2191 * m4/hash.h (m4_hash_apply_func): Replacement type for...
2192 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
2193 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
2195 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
2196 (M4_IS_IDENT): Detect characters that can be safely used in
2198 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
2199 * m4/macro.c: Corrected grammar in some comments. Use `token'
2200 rather than `td' for m4_token variables.
2201 (m4_process_macro): If we find a dollar followed by some
2202 M4_IS_IDENT characters, replace that with the contents of the argv
2203 entry with offset stored in the m4_token_arg associated with the

2208 Begin preparations for supporting formal parameters in m4 macros.
2210 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
2211 the details of a formal parameter.
2212 (m4_token): Add an arg_signature member to hold a hash table for
2213 looking up formal parameters.
2214 * m4/input.c: Update more bitrotted comments.
2215 (m4_push_builtin): Initialise arg_signature member.
2216 (init_builtin_token): Copy arg_signature member.
2217 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
2218 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
2220 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
2221 (m4_macro_pushdef, m4_macro_define): ...these, And...
2222 (m4_symbol_token): ...wrapped around this new function, which
2223 vastly simplifies the arguments required by the functions it
2225 Changed all callers.
2227 2003-06-05 Gary V. Vaughan <gary@gnu.org>
2229 * m4/macro.c: Format changes.
2231 2003-06-04 Gary V. Vaughan <gary@gnu.org>
2233 * m4/input.c: Updated various bitrotted comments.
2234 (m4_push_builtin): Just pass the whole m4_token, rather than
2235 extracting all the fields in the caller. This also allows us to
2236 check the token type for consistency.
2237 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
2238 Renamed to builtin_funcs, builtin_peek, builtin_read,
2239 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
2240 the code. Changed all callers.
2241 (struct input_block): Similarly renamed u_m member to u_b, and
2242 changed all callers.
2243 (m4_next_token): Use bzero to initialise the data fields.
2244 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
2246 2003-05-29 Gary V. Vaughan <gary@gnu.org>
2248 These changes were necessary to get m4 to build on my iBook
2249 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
2250 (GCC) 3.1 20020420 (prerelease)":
2252 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
2253 inclusion of module loader headers.
2254 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
2255 * m4/Makefile.am: Ditto.
2256 (libm4_la_LIBADD): Added $(LTLIBINTL).
2257 * m4/utility.c (program_name): Removed declaration in favour of
2258 the one already in error.c!
2259 * m4/m4module.h (program_name): Define to program_invocation_name
2260 when using GNU C library. Use an explicit extern declaration.
2261 (interactive, sync_output, debug_level, hash_table_size)
2262 (no_gnu_extensions, prefix_all_builtins, max_debug_argument_length)
2263 (suppress_warnings, warning_status, nesting_limit, discard_comments)
2264 (lquote, rquote, bcomm, ecomm, m4_bad_argc, m4_skip_space)
2265 (m4_numeric_arg, m4_shipout_int, m4_shipout_string, m4_dump_args)
2266 (m4_debug, m4_debug_init, m4_debug_exit, m4_debug_decode)
2267 (m4_debug_flush_files, m4_debug_set_output, m4_debug_message_prefix)
2268 (m4_trace_prepre, m4_trace_pre, m4_trace_post, m4_sysval)
2269 (m4_expansion_level, m4_expand_ranges, m4_expand_input)
2270 (m4_call_macro, m4_process_macro, m4_syntax_table, m4_current_file)
2271 (m4_current_line, m4_current_diversion, m4_output_current_line):
2272 Don't rely on default, use an explicit extern.
2273 * m4/error.h (error, error_at_line, error_print_progname)
2274 (error_message_count, error_one_per_line): Ditto.
2275 * m4/ltdl.c: Update from CVS libtool.
2277 * commit: Update from CVS cvs-utils.
2279 2002-11-04 Akim Demaille <akim@epita.fr>
2281 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
2283 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
2285 2002-11-04 Akim Demaille <akim@epita.fr>
2287 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
2289 2002-11-04 Akim Demaille <akim@epita.fr>
2291 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
2292 used as `external', and Libtool 1.4.3.
2294 (LTLIBOBJS): Don't play with it.
2296 * Makefile.am (SUBDIRS): Remove intl.
2297 (ACLOCAL_AMFLAGS): Add -I config.
2298 (EXTRA_DIST): Add config/config.rpath.
2301 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
2303 2002-05-29 Gary V. Vaughan <gary@gnu.org>
2305 Preparations for refactoring syntax tables to allow reverse
2306 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
2307 speed of normal lookups in an array of unsigned short.
2309 * m4/input.c (single_quotes, single_comments, use_macro_escape):
2311 * m4/m4private.h (m4__single_quotes, m4__single_comments,
2312 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
2313 is for internal symbols which unavoidably pollute the global
2314 namespace, but are not published APIs.
2315 Adjusted all callers.
2316 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
2317 m4_set_comment, m4_set_syntax, set_syntax_internal,
2318 unset_syntax_attribute): Moved from this file...
2319 * m4/syntax.c: New. ...to this file.
2320 Also added an m4_syntax_exit stub for orthogonality.
2321 * src/main.c (main): Use it.
2322 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
2323 * m4/m4module.h: Reformatting. New prototypes.
2325 2002-05-29 Gary V. Vaughan <gary@gnu.org>
2327 * bootstrap (aclocal_apiversion): The aclocal apiversion is
2328 distinct from the automake release number (in that the apiversion
2329 apparently has no micro-version-component).
2330 (aclocal_apilibdir): Use it.
2332 2002-05-28 Gary V. Vaughan <gary@gnu.org>
2334 * m4/hash.c (m4_hash_resize): New function.
2335 * m4/hash.h: Add prototype.
2336 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
2337 benchmarking to find a good value for, say, autoconf. This is
2338 already a little quicker than before for me.
2340 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
2341 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
2343 * m4/hash.h: Adjust prototypes.
2345 2002-01-22 Akim Demaille <akim@epita.fr>
2347 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
2349 * tests/Makefile.am (package.m4): New.
2350 * tests/atlocal.in: Adjust to CVS Autotest.
2351 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
2352 * configure.ac: LIBOBJ is a forbidden string.
2353 Simplify AM_INIT_AUTOMAKE invocation.
2354 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
2357 2001-10-19 Akim Demaille <akim@epita.fr>
2359 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
2361 2001-10-19 Akim Demaille <akim@epita.fr>
2363 * m4/input.c (m4_next_token): Display where was opened what is
2366 2001-10-19 Akim Demaille <akim@epita.fr>
2368 * m4/macro.c (expand_argument): Display where was opened what is
2371 2001-10-18 Akim Demaille <akim@epita.fr>
2373 * m4/input.c, modules/m4.c: Formatting changes.
2375 2001-10-17 Gary V. Vaughan <gary@gnu.org>
2377 * bootstrap: s/configure.in/configure.ac/
2379 2001-10-16 Gary V. Vaughan <gary@gnu.org>
2381 * m4/symtab.c (m4_symbol_destroy): This function calls
2382 m4_symbol_popdef, which recycles a symbols memory when the last
2383 definition is popped. Since we were passing the address of the
2384 symbol name found in the symbol table, and it was being removed
2385 partway through m4_symbol_destroy() we were referencing freed
2386 memory for the balance of the function. Now we take a copy of the
2387 symbol name tring and use that as a key into the symbol
2388 table... that way if the original symbol name is freed, the copy
2391 2001-10-13 Akim Demaille <akim@epita.fr>
2393 * m4/ltdl.c: Update.
2395 2001-10-13 Akim Demaille <akim@epita.fr>
2397 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
2398 Don't gettextize internal error messages.
2400 2001-10-13 Akim Demaille <akim@epita.fr>
2402 * tests/macros.at (Arity and defn): New failing test.
2403 (Arity, defn, and freeze): New.
2405 Fix `Arity and defn'.
2407 * m4/input.c (m4_push_macro): Don't forget the arity.
2408 * modules/m4.c (defn): Likewise.
2410 2001-10-13 Akim Demaille <akim@epita.fr>
2412 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
2414 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
2415 (Propagation of traceon, Propagation of --trace): this new file.
2417 2001-10-13 Akim Demaille <akim@epita.fr>
2419 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
2420 interface instead of (name, argc...).
2421 Upon failure, specify which argument was guilty.
2424 2001-10-13 Akim Demaille <akim@epita.fr>
2426 * modules/evalparse.c: Save translators' time: don't translate
2427 internal error messages.
2428 (m4_evaluate): Simplify/normalize error messages.
2429 * doc/m4.texinfo (Eval): Adjust.
2431 2001-10-13 Akim Demaille <akim@epita.fr>
2433 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
2434 where no checking is needed.
2435 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
2436 interface instead of (name, argc...).
2438 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
2441 2001-10-13 Akim Demaille <akim@epita.fr>
2443 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
2444 exclude the builtin name from the count.
2445 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
2446 calling ifelse with a single argument is valid.
2447 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
2448 with 1 and 2 args, mostly to strengthen the test suite.
2450 2001-10-13 Akim Demaille <akim@epita.fr>
2452 * m4/output.c (m4_make_diversion, m4_insert_file)
2453 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
2455 2001-10-12 Gary V. Vaughan <gary@gnu.org>
2457 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
2458 since we call these things builtins in the rest of the code!
2460 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
2462 2001-10-12 Gary V. Vaughan <gary@gnu.org>
2464 Rather than forcing each builtin definition to manage its own
2465 argument range checking, tabulate the maxima and minima for all
2466 builtins in each module. This forces us to consider what the
2467 valid ranges for each builtin should be, and moves the checking
2468 code out of each builtin implementation and into the builtin
2469 caller infrastructure.
2471 * m4/m4module.h (struct m4_builtin): Add argument minima and
2473 * m4/m4private.h (struct m4_token): Reflect them here too.
2474 * m4/input.c (struct input_block): ...and here.
2475 (m4_token_copy): New function for token copying.
2476 (init_macro_token): Copy them from a token to the input stack.
2477 (m4_next_token): Don't forget to initialise them for text
2479 * m4/macro.c (expand_argument): Use m4_token_copy, and also
2480 check argument counts before calling the builtin handler.
2481 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
2482 (m4_symbol_macro): Likewise.
2483 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
2484 parameters. Updated all callers.
2485 (m4_builtin_define): Ditto.
2486 (m4_macro_pushdef, m4_macro_define): Ditto.
2487 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
2488 * modules/evalparse.c: Declare argument counts for defined
2489 builtins and remove explicit calls to m4_bad_argc().
2490 * modules/gnu.c: Ditto.
2491 * modules/load.c: Ditto.
2492 * modules/m4.c: Ditto.
2493 * modules/modtest.c: Ditto.
2494 * modules/mpeval.c: Ditto.
2495 * modules/perl.c: Ditto.
2496 * modules/shadow.c: Ditto.
2497 * modules/stdlib.c: Ditto.
2498 * modules/time.c: Ditto.
2501 2001-10-10 Gary V. Vaughan <gary@gnu.org>
2503 The trace semantics now attach the trace bit to a symbol name.
2504 For as long as a traceon(`foo') is active, calls to foo will be
2505 traced regardless of intervening undefines or module unloads.
2506 Fixed the flag propogation issues differently to the fixes
2507 reverted with the last attempt at nailing down trace:
2509 * m4/m4private.h: This file is not visible outside of the m4
2510 source tree, so I removed all the `M4_' and `m4_' prefixes to save
2511 on typing. Updated all clients.
2512 (m4_token): New typedef contains the fields that need to be passed
2513 around with the low level tokeniser.
2514 (m4_token_data): Removed.
2515 (m4_symbol): Now contains the traced flag again.
2516 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
2517 the trace bit set. This change is contained entirely within this
2518 module and doesn't leak out into the callers. Updated all
2520 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
2521 new fields in m4_token. Updated all clients.
2522 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
2523 that `groks_macro_args' and `blind_if_no_args' flags are retained
2524 when defn() results are passed around in m4 code. Updated all
2526 (m4_builtin_define): Ditto.
2527 (m4_macro_pushdef, m4_macro_define): Ditto.
2528 * m4/input.c (struct input_block): Add a flags field to facilitate
2530 (m4_push_macro): ...use it.
2531 (init_macro_token): Retrieve it.
2532 (m4_next_token): Initialise it.
2533 * m4/macro.c (expand_argument): Copy it.
2534 * m4/m4module.h: Adjust.
2535 * tests/builtins.at: Adjust the expected output of the trace
2536 tests to reflect the change in semantics.
2537 * tests/modules.at (modules: trace): Check that unloading a
2538 module which supplies a traced symbol definition doesn't lose te
2541 2001-10-07 Gary V. Vaughan <gary@gnu.org>
2543 * modules/gnu.c (m4_macro_table): Display the timetamp when
2544 expanding __m4_version__.
2546 * configure.ac (--with-modules): Forgot a comma in the
2547 AC_HELP_STRING parameter list.
2549 2001-10-05 Gary V. Vaughan <gary@gnu.org>
2551 * bootstrap: Remove aclocal.m4t when it is no longer required.
2553 2001-10-05 Akim Demaille <akim@epita.fr>
2555 * tests/Makefile.am: Adjust for gnuprog2.
2556 * tests/m4.in: There can be a leading path.
2557 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
2558 * tests/testsuite.at: Adjust to the most recent Autotest.
2559 (AT_CHECK_M4_FILTER): Fix and rename as...
2561 * tests/others.at: Use it.
2563 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
2564 variable in shell scripts, one uses `$'...
2566 2001-10-04 Gary V. Vaughan <gary@gnu.org>
2568 * configure.ac: `rm -f $m4_getopt_h' was lost.
2570 2001-10-04 Gary V. Vaughan <gary@gnu.org>
2572 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
2573 time. Define it for config.h in order to...
2574 * src/main.c (main): ...display the timestamp for --version.
2576 2001-10-04 Akim Demaille <akim@epita.fr>
2578 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
2579 previous builtins `regexp' and `patsubst'.
2580 (regexp, patsubst): Use them.
2581 (eregexp, epatsubst): New builtins.
2582 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
2583 (Epatsubst and Patsubst, Eregexp and Regexp): these.
2584 (Extensions): More info on REs.
2586 2001-10-04 Akim Demaille <akim@epita.fr>
2588 * modules/modtest.c (init_handler): Consistently output to stderr.
2589 (finish_handler): New.
2590 (test): The `if' is an `assert'.
2591 * tests/modules.at: Adjust.
2593 2001-10-04 Akim Demaille <akim@epita.fr>
2595 * m4/utility.c (m4_bad_argc): Detail the mismatches.
2597 2001-10-01 Akim Demaille <akim@epita.fr>
2599 * tests/generate.awk: Tag the tests with `documentation'.
2600 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
2601 Use the make the existing modtest tests more uniform, and complete
2602 the set of possibilities.
2604 2001-10-01 Akim Demaille <akim@epita.fr>
2606 * config/gmp.m4: Consult the user before using GMP: use
2608 * configure.ac: Adjust.
2609 * modules/gmp.c: No protection needed as the module is not built
2612 2001-10-01 Akim Demaille <akim@epita.fr>
2614 * tests/generate.awk: Remove debugging code.
2615 (fatal): Specify the current location.
2617 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
2618 * modules/gnu.c, modules/m4.c: Use M4ARG.
2620 2001-10-01 Akim Demaille <akim@epita.fr>
2622 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
2623 (m4_regexp_compile): New.
2624 (regexp, patsubst): Use it.
2626 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2628 Reinstate the memory handling improvements from the patch I just
2629 reverted. Relevant ChangeLog entries repeated here:
2631 * m4/module.c (m4_module_remove): New function that holds the core
2632 of the old m4_module_unload.
2633 (m4_module_unload): Use it.
2634 (m4_module_unload_all): When we know the modules will never be
2635 used again (i.e. on exit), free up as much module memory as
2636 possible. There are still some artifacts from resident modules
2637 living inside ltdl.c, but everything else is freed.
2638 * m4/debug.c (m4_debug_exit): Free memory allocated in
2640 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
2641 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
2642 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
2643 * m4/m4module.h: Updated prototypes.
2644 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
2645 * m4/hash.h: Updated prototypes.
2646 * src/main.c (main): Use all these new functions to clean up as
2647 much memory as possible before exit.
2649 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2651 Reverted my large patch for removing the old m4_symbol
2652 structure on 2001-09-20. We are still not happy about the way
2653 trace works in conjunction with defn and undefine, and leaving
2654 the reverted patch active prevents us from moving the traced
2655 bit from the definition back to the symbol.
2657 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2659 * configure.in: Moved to...
2660 * configure.ac: ...here. Added a libtool like timestamped
2661 banner, and tidied up the libltdl cruft.
2662 * config/mkstamp: Script to extract a timestamp from ChangeLog.
2663 * modules/Makefile.am (INCLTDL): Removed. This is required
2664 only when libltdl is configured in a subdirectory.
2665 * src/Makefile.am: Ditto.
2666 (LIBADD_DL): No need to add this again, libtool already knows
2667 that libm4.la depends on it.
2668 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
2671 * TODO: stackovf.c is basically broken.
2672 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
2674 2001-09-28 Akim Demaille <akim@epita.fr>
2676 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
2678 2001-09-27 Akim Demaille <akim@epita.fr>
2680 * tests/m4.in: Don't use short options.
2681 Simplify the stderr signature normalization.
2683 2001-09-27 Akim Demaille <akim@epita.fr>
2685 tests/m4 shall be position independent.
2689 * tests/testsuite.at: No args to AT_INIT.
2690 * configure.in, tests/Makefile.am: Adjust.
2692 2001-09-22 Akim Demaille <akim@epita.fr>
2694 Autotest has changed again.
2696 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
2697 (package.m4): Remove.
2698 * configure.in: Adjust to LIBADD_GMP.
2700 2001-09-21 Gary V. Vaughan <gary@gnu.org>
2702 * config/gmp.m4 (AC_ARG_WITH): Removed.
2703 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
2704 (AC_LIB_GMP): When performing a test compile against libgmp,
2705 include the header gmp.h if possible, and link against -lgmp. If
2706 they both work define USE_GMP.
2707 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
2708 (mpeval_LTX_init_func): Complain on load that there was no libgmp
2711 2001-09-20 Gary V. Vaughan <gary@gnu.org>
2713 * m4/evalparse.c: Moved to...
2714 * modules/evalparse.c: ...here. This code is shared between
2715 modules/mpeval.c and modules/m4.c, so there is no need to pollute
2716 the libm4 API with its details. Moderately rewritten to interface
2717 into its clients more simply.
2718 * m4/eval.c: Deleted. Migrated functionality to...
2719 * modules/m4.c: ...here.
2720 (builtin_eval): Implemented in terms of the new interface style.
2721 * modules/mpeval.c (builtin_mpeval): Ditto.
2722 * m4/m4module.h: Removed references to the former m4/eval.c.
2723 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
2724 (EXTRA_libm4_la_SOURCES): Deleted.
2725 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
2726 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
2728 2001-09-20 Akim Demaille <akim@epita.fr>
2730 * config/gmp.m4 (AM_WITH_GMP): Rename as...
2732 By default, use gmp.
2734 * configure.in: Adjust.
2735 Use Automake conditionals for USE_GMP.
2736 Always compute sizeof (long long int).
2737 This was a bug BTW, as `eval' (not `mpeval') depends on it:
2738 before, it was used _only_ if mpeval was not activated.
2739 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
2740 (mpeval_la_LIBADD): New macros.
2741 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
2743 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
2744 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
2747 2001-09-20 Akim Demaille <akim@epita.fr>
2749 * tests/Makefile.am (package.m4): New.
2750 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
2752 2001-09-20 Gary V. Vaughan <gary@gnu.org>
2754 More cleanup. After the last patch, m4_symbol holds nothing but
2755 the head of a chain of m4_token_data. So I have removed the old
2756 m4_symbol, so that m4_token_data chains are stored directly in the
2757 value cell of a hash table node. But there's more... m4_symbol
2758 was a more natural name for the symbol value cell, and now that it
2759 is gone I have renamed the former m4_token_data structure to
2760 m4_symbol. This change turned out to be a pig to get right, since
2761 the original code didn't need to modify the value cell itself,
2762 since changing the chain happened inside the m4_symbol that used
2763 to be returned -- I had to pass the address of the value cell
2764 across various function calls, incase the head value changed. I
2765 also tightened up the memory management to help me find a nasty
2766 memory corruption bug that took me all night to track down...
2768 * m4/m4private.h (struct m4_symbol): Removed.
2769 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
2771 * m4/hash.c (m4_hash_iterator_value): Return the address of the
2772 value cell. Updated all callers.
2773 * m4/symtab.c: Took advantage of the simplification in the data
2774 structures to rewrite a lot of this file more simply. There is
2775 still some room for optimisation here, but we should tackle that
2776 systematically closer to the release.
2778 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
2779 revealed. This version is ahead of CVS libtool until I get chance
2780 to flush my changes.
2781 * m4/module.c (m4_module_remove): New function that holds the core
2782 of the old m4_module_unload.
2783 (m4_module_unload): Use it.
2784 (m4_module_unload_all): When we know the modules will never be
2785 used again (i.e. on exit), free up as much module memory as
2786 possible. There are still some artifacts from resident modules
2787 living inside ltdl.c, but everything else is freed.
2788 * m4/debug.c (m4_debug_exit): Free memory allocated in
2790 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
2791 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
2792 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
2793 * m4/m4module.h: Updated prototypes.
2794 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
2795 * m4/hash.h: Updated prototypes.
2796 * src/main.c (main): Use all these new functions to clean up as
2797 much memory as possible before exit.
2799 2001-09-18 Gary V. Vaughan <gary@gnu.org>
2801 The `traced' flag needs to be attached to the definition of a
2802 symbol rather than the current symbol containing the definition.
2803 Implementing this showed up some long standing post 1.4 bugs in
2804 flag propogation which I also fixed.
2806 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
2807 (struct m4_token_data): And add it back in here.
2808 * m4/input.c (init_macro_token): Propogate the traced flag
2810 * m4/macro.c (expand_argument): Ditto.
2811 * tests/builtins.at (trace2, trace3): New tests based on Akim's
2814 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2816 * m4/m4private.h (struct m4_token_data): Simplified by removing
2817 the redundant `traced' flag, and one level of structure nesting.
2818 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
2819 * m4/input.c (init_macro_token): No need to initialise removed
2821 * m4/macro.c (expand_argument): No need to copy it either.
2822 * m4/utility.c (m4_token_data_func_traced): Or provide an access
2825 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
2826 dependant on multiple symbols with the same key, so preserving
2827 relative symbol order in each bucket during resizing is no longer
2828 required. The resize function is considerably faster as a result.
2830 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
2831 s/m4_symbol_insert/m4_symbol_define/g;
2832 s/m4_builtin_insert/m4_builtin_define/g;
2833 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
2835 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2837 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
2838 commits, the m4_lookup_symbol dispatch function is split into
2839 specialised functions that must be called directly.
2841 * m4/m4module.h (m4_symbol_lookup_t): Removed.
2842 * m4/symtab.c (m4_lookup_symbol): Removed.
2843 (m4_symbol_builtin, m4_symbol_macro): New functions.
2844 * m4/builtin.c (m4_builtin_define): Split into...
2845 (m4_builtin_pushdef, m4_builtin_insert): ...these.
2846 (m4_macro_define): Split into...
2847 (m4_macro_pushdef, m4_macro_insert): ...these.
2848 * src/main.c (main): Set command line macros from `-D' parameters
2849 using `m4_macro_define'.
2851 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2853 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
2854 this from m4_remove_table_reference_symbols().
2855 * m4/m4module.h, m4/module.c: Updated all references.
2857 2001-09-07 Akim Demaille <akim@epita.fr>
2859 * modules/stdlib.c, modules/times.c: Misc cleanups.
2861 2001-09-07 Akim Demaille <akim@epita.fr>
2863 * configure.in: We now need Autoconf 2.52e.
2864 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
2865 and `M4_SYMBOL_DELETE'.
2866 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
2867 * src/main.c (main): Adjust.
2869 2001-09-06 Gary V. Vaughan <gary@gnu.org>
2871 Fix the obstack.h problem once and for all! At configure time we
2872 can test for a system supplied obstack.h: depending on the
2873 result, we now generate system.h with an #include of the correct
2874 header. As a bonus, I've also added a --with-included-obstack,
2875 incase the user doesn't like the system obstack for some
2876 reason... and also we can test the shipped obstack on a system
2877 that has oe of its own. We also now need to be careful to add
2878 build directories to the include search path, since the generated
2879 system.h will be in the build tree.
2881 * configure.in (AC_CONFIG_FILES): Generate system.h from
2883 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
2884 include the system obstack header or the copy shipped with M4.
2885 Allow the user to override configure and force the build to use
2886 the shipped version.
2887 * m4/system-h.in: New file, template for...
2888 * m4/system.h: ...this. Now deleted.
2889 * m4/m4module.h: Include system.h before everything else.
2890 * src/freeze.c: Ditto.
2891 * m4/Makefile.am (dist-hook): Remove generated system.h.
2892 (INCLUDES): Check builddir for generated headers before checking
2894 * modules/Makefile.am (INCLUDES): Ditto.
2895 * src/Makefile.am (INCLUDES): Ditto.
2897 2001-09-05 Gary V. Vaughan <gary@gnu.org>
2899 * TODO: Remove the items that have been addressed already.
2901 2001-09-05 Akim Demaille <akim@epita.fr>
2903 * src/main.c (main): Standardize --version.
2905 2001-09-05 Akim Demaille <akim@epita.fr>
2907 * modules/format.c (format): Have a bigger `str'.
2909 2001-09-05 Akim Demaille <akim@epita.fr>
2911 Rationalize warnings, reporting the macro name as if it were a
2912 program name, and assertions.
2914 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
2916 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
2918 Use assert for internal errors.
2919 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
2921 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
2923 * tests/builtins.at (pushpop): Adjust.
2925 2001-09-05 Akim Demaille <akim@epita.fr>
2927 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
2930 2001-09-05 Akim Demaille <akim@epita.fr>
2932 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
2933 * m4/macro.c, m4/symtab.c: Adjust.
2935 2001-09-05 Akim Demaille <akim@epita.fr>
2937 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
2938 (m4_symbol_pop, m4_symbol_del): this.
2939 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
2940 (m4_symbol_popdef, m4_symbol_delete): New.
2941 (m4_lookup_symbol): Adjust.
2942 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
2944 2001-09-05 Akim Demaille <akim@epita.fr>
2946 * m4/m4module.h (m4_symbol_lookup): Rename as...
2947 (m4_symbol_lookup_t): this.
2949 2001-09-05 Akim Demaille <akim@epita.fr>
2951 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
2953 * m4/symtab.c (m4_lookup_symbol): Adjust.
2955 2001-09-03 Gary V. Vaughan <gary@gnu.org>
2957 Bootstrap will now work with Libtool 1.4.1 or higher:
2958 * bootstrap: Remove stale autom4te.cache files when
2960 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
2962 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
2963 libtool.m4 directly.
2964 Run libtoolize to refresh ltmain.sh.
2965 * config/ltmain.sh: Deleted.
2966 * acinclude.m4: Deleted.
2967 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
2969 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
2970 implementation for the cvs impaired libtool user.
2972 2001-09-03 Akim Demaille <akim@epita.fr>
2974 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
2976 Avoid using `default' in switch, as it hides useful compiler
2977 warnings when a case is forgotten.
2979 2001-09-03 Akim Demaille <akim@epita.fr>
2981 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
2982 is no such thing as `WITH_MODULES'.
2984 2001-09-03 Akim Demaille <akim@epita.fr>
2986 Improve the test suite's selfcontainedness.
2988 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
2989 (Include, Undivert): Tag the other input files.
2990 * tests/generate.awk: Catch `@comment file:'.
2991 `-I $src' is no longer needed.
2992 `next' is really like `return': the rest is skipped.
2993 Adjust to `input.m4'.
2994 (fatal): New function.
2995 * tests/foo, tests/incl.m4: Remove.
2997 2001-09-01 Gary V. Vaughan <gary@gnu.org>
2999 The shadowing mechanism and, infact, the whole symbol table
3000 implementation was creaking under the weight of the features piled
3001 on top of it. We now have a separate hash table module which will
3002 dynamically resize to keep symbol density withing good performace
3003 limits, and a new symtab module layered above it. Symbol lookups
3004 are now marginally more efficient (since the shadowed flag is no
3005 longer required) and symbol removal, such as on module unload, is
3006 considerably faster due to a reorganisation of the data structures
3009 * src/main.c (main): Don't mention `-H'.
3010 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
3013 * m4/hash.c: New generalised dynamic hash table data structure
3015 * m4/hash.h: Public interface.
3016 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
3017 (libm4_la_SOURCES): Add hash.c.
3018 * m4/symtab.c: More or less rewritten from scratch, within the
3019 bounds of the previous API.
3020 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
3021 call. Updated all callers.
3022 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
3023 declarations to reflect API changes.
3024 (M4INIT): Generate a declaration too, to avoid the warning with
3025 --enable-debug builds.
3028 * m4/utility.c (hash_table_size): Removed.
3029 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
3030 names, which are then looked up by builtin_dumpdef() as necessary.
3031 This implies a small speedup in builtin_symbols(), which discarded
3032 all of the symbol info under the old call.
3033 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
3034 shadowing is implicit in respect to the new data structures.
3035 symbol names are no longer duplicated here, they are stored in the
3036 key field of the hash table.
3037 Moved macro_args and blind_no_args...
3038 (m4_token_data): ...to here.
3039 m4/macro.c (expand_macro): Added a name argument since the symbol
3040 name is no longer copied into each struct m4_symbol. Modified all
3042 (collect_arguments): Ditto.
3043 * modules/m4.c (set_trace): Ditto.
3044 * modules/gnu.c (builtin_symbols): Updated.
3045 * src/freeze.c (produce_symbol_dump): Much improved in light of
3046 the improved symbol table layout.
3048 2001-09-01 Gary V. Vaughan <gary@gnu.org>
3050 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
3052 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
3053 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
3054 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
3055 SYMBOL_HANDLE): Ditto.
3056 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
3057 modules/gnu.c, modules/m4.c, src/freeze.c,
3058 src/main.c: Updated all references.
3060 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
3061 Automake 1.5 chokes on dynamic source file lists, Besides, it is
3062 already listed in m4_LDADD... how did that ever used to work?
3063 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
3065 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
3066 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
3068 * tests/m4: Don't call the m4 wrapper script with libtool, it
3069 works fine all by itself.
3071 2001-08-30 Gary V. Vaughan <gary@gnu.org>
3073 The experimental `changeword' feature never took off, and has
3074 no obvious advantages over `changesyntax' to compensate the
3075 enormous speed penalty it carries:
3076 * configure.in (ENABLE_CHANGEWORD): Removed.
3077 * m4/m4module.h (m4_set_word_regexp): Removed.
3078 * m4/m4private.h (m4_token_data): Removed original_text field.
3079 * m4/utility.c (m4_token_data_orig_text): Removed.
3080 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
3081 * m4/macro.c: Ditto.
3082 * src/main.c: Ditto.
3083 * modules/Makefile.am (changeword.la): Removed.
3084 * modules/changeword.c: File removed.
3085 * doc/m4.texinfo: References to changeword and --word-regexp
3087 * po/POTFILES.in: modules/changeword.c removed.
3088 * tests/atlocal.in (ENABLE_CHANGEWORD): Removed.
3089 * tests/builtins.at (changeword): Test removed.
3091 2001-08-30 Akim Demaille <akim@epita.fr>
3093 * bootstrap.sh: Create aclocal.m4 instead of modifying it.
3094 This also help having a single list of m4 files: in
3096 * config/Makefile.am (STANDARD_MACROS): Rename as...
3097 (ACLOCAL_MACROS): this.
3098 (list-standard-macros): Remove.
3101 2001-08-29 Gary V. Vaughan <gary@gnu.org>
3103 In an attempt to moderate my egomania...
3104 * tests/modules.at: Remove attributions.
3106 * tests/generate.awk: When making substitutions to "@&t@", either
3107 "&" or "\&" in the substitution string argument to gsub refer back
3108 to the matched text. "@\\&t@" seems to work though, Tests 43 and
3111 2001-08-29 Akim Demaille <akim@epita.fr>
3113 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)
3114 (include, indir, multiquotes, patsubst, pushdef/popdef, regexp)
3115 (sync-lines, trace, translit, undivert, wrap): Move to...
3116 * tests/builtins.at: this new file.
3117 * tests/others.at (Discard comments, import-environment): Move to...
3118 * tests/options.at: this new file.
3120 2001-08-29 Akim Demaille <akim@epita.fr>
3122 * tests/others.at (Freezing modules)
3123 (--module-directory: absolute path, modpath2, modpath3)
3124 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
3125 * tests/modules.at: here, new file.
3126 * tests/others.at, tests/generate.awk: Add a banner.
3127 * tests/testsuite.at: Adjust.
3128 (AT_CHECK_M4_FILTER): New, but unused.
3130 2001-08-29 Akim Demaille <akim@epita.fr>
3132 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
3134 * tests/others.at (wrap): Inline wrap.m4.
3135 (shadow): Inline shadow.m4.
3136 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
3137 * tests/m4: Simplify.
3139 2001-08-29 Akim Demaille <akim@epita.fr>
3141 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
3144 2001-08-29 Akim Demaille <akim@epita.fr>
3146 * tests/generate.awk (normalize): s/@__@/@&t@/.
3148 2001-08-28 Akim Demaille <akim@epita.fr>
3150 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.
3152 2001-08-28 Gary V. Vaughan <gary@gnu.org>
3154 * bootstrap (generate.awk): Generate test cases with new script.
3156 2001-08-27 Akim Demaille <akim@epita.fr>
3158 * tests/Makefile.am (installcheck-local): Don't use
3159 `dc_install_base' which is not visible here, but `exec_prefix'
3160 which is clearly the RT anyway.
3161 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
3162 related to testing a now installed m4.
3163 * tests/m4: Do it here.
3165 2001-08-27 Akim Demaille <akim@epita.fr>
3167 * tests/others.at (indir): Formatting change.
3169 2001-08-27 Akim Demaille <akim@epita.fr>
3171 * tests/Makefile.am (installcheck-local): New.
3172 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
3174 Prefer options over envvars.
3175 * src/main.c (main): First bug caught by the test suite (yeah!):
3176 --batch lacked a `break' which resulted in an accidental
3177 invocation of --discard-comments.
3179 2001-08-27 Akim Demaille <akim@epita.fr>
3181 * tests/others.at (capitalize, changeword, comments, ddivert)
3182 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
3183 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
3184 (sysv-args, trace, translit, undivert): Don't rely on files in
3185 examples/: AT_DATA them.
3187 2001-08-27 Akim Demaille <akim@epita.fr>
3189 Let the test suite use a wrapper around the not installed m4 to
3190 pretend it is (installed).
3192 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
3193 such a way that m4 does not process them.
3194 * configure.in: The package name seems to be `m4', not `M4'.
3196 * tests/atlocal.in (at_package, M4): Remove.
3197 * tests/testsuite.at, tests/others.at: Use m4, not $M4.

3201 * tests/Makefile.am (CLEANFILES): Remove.
3202 (DISTCLEANFILES, clean-local): New.

3205 2001-08-27 Akim Demaille <akim@epita.fr>
3207 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
3208 Don't use aclocal: it's written by hand.
3209 * aclocal.m4: m4_include all the files instead of being built by
3211 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
3212 until it reads the traces by itself.
3213 * configure.in: Require Autoconf 2.42c as we are now using
3214 AC_CONFIG_TESTDIR instead of AT_CONFIG.
3215 Catch unexpanded `jm_' macros.
3216 * config/atconfig.m4: Remove.
3217 * config/error.m4: new.
3218 * config/Makefile.am: Ship the files included by aclocal.m4.
3219 * tests/Makefile.am (TESTSUITE_SOURCES): Rename as...
3220 (TESTSUITE_AT): this, to please Automake.
3221 (TESTSUITE): This target uses autotest/autotest.m4, not
3222 autotest/general.m4.

3229 2001-08-20 Gary V. Vaughan <gary@gnu.org>
3231 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
3232 Robert Collins, building on Cygwin no longer requires Windows
3233 import and export symbol decorations.
3234 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.
3235 * m4/error.h (M4_SCOPE) [cygwin*]: Ditto.

3248 2001-08-20 Gary V. Vaughan <gary@gnu.org>
3250 Ansify the source. Previously we had a mix, where my code was
3251 in a K&R compatible style, and the preexisting code was in ANSI
3252 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
3253 and now the code base is much cleaner.
3255 * m4/system.h: Remove M4_PARAMS macro and all users. Remove
3256 VOID macro and all users.

3296 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
3297 * modules/m4.c (undivert): Disable the possibility of undiverting
3298 several files at once: it is not documented, it is inconsistent
3299 with the other macros, it can be straightforwardly mocked by
3300 several invocations, and most importantly, it prevents the
3301 possibility of other kinds of extension.
3302 Use `m4_numeric_arg'.
3304 2001-08-20 Akim Demaille <akim@epita.fr>
3306 * examples/include.m4: Typo.
3307 * tests/generate.awk: Really add it.
3308 * tests/Makefile.am: Adjust.
3309 * tests/others.at (Discard comments): It sure fails without `-c'.
3310 (include, undivert): Add -I examples/.
3312 2001-08-20 Akim Demaille <akim@epita.fr>
3314 Use sprintf, not ecft and friends since it is standard, portable,
3315 simplifies the code, and since the latter is even deprecated
3316 according to the GNU libc documentation.
3318 * modules/format.c: Drop evct support.
3320 2001-08-19 Gary V. Vaughan <gary@gnu.org>

3422 2001-08-17 Akim Demaille <akim@epita.fr>
3424 others.at no longer depends on other-tests/.

3464 Drop Autoconf 2.13 compatibility.
3466 * configure.in (changeword): No need to undefine it, as anyway if
3467 it's defined, M4sugar moved it as m4_changeword.
3468 And anyway, proper quotation is enough.
3469 (m4_pattern_allow): As it exists in 2.50, just use it.
3470 (AC_OUTPUT): Split in AC_CONFIG_FILES and AC_CONFIG_COMMANDS.
3471 Don't handle Gettext's duties, let it handle them.

3483 (MAINTAINERCLEANFILES): Remove texinfo.tex and mdate-sh which are

3525 (M4FINISH_HANDLER): And similarly for finish functions.
3526 * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER
3527 -- Add indirection to the CONC macro so that arguments are
3529 * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
3530 * modules/shadow.c (m4_init_module): Ditto.

3533 * modules/perl.c (m4_init_module): Ditto. And Ditto.
3534 (m4_finish_module): Replaced with M4FINISH_HANDLER.

3538 (m4_module_data): ...structure without all the wrapper fields.
3539 Instances of this new structure are stored associated lt_dlhandles

3542 instead of the old module argument.
3543 (m4_builtin_table_install): Ditto.
3544 * modules/load.c (m4_resident_module): Removed. This is no
3545 longer implemented as a magic symbol...
3546 * modules/m4.c (m4_resident_module): Ditto.
3547 * modules/load.c (M4INIT_HANDLER): ...the module init function now

3560 (libm4_la_SOURCES): Delete list.c reference.

3563 various tokens that are passed between functions.
3564 (struct m4_symbol): Removed the module field. The
3565 module association does not belong with the symbol...
3566 * m4/input.c (struct m4_builtin): ...it belongs with the builtin
3567 that the module implementation code is from. Added a handle
3569 (m4_push_macro): Add a `handle' argument. Changed all callers.

3585 (CDPATH) Neutralize.
3586 * tests/gethem: Use them.
3588 2001-08-14 Gary V. Vaughan <gary@gnu.org>
3590 * config/ltmain.sh: Doh! Import again for a quoting fix that

3605 shell variable m4_cv_func_obstack_h.
3606 * tests/defs (M4): Be more careful about relative path to libtool
3607 script and m4 binary by using $srcdir.
3609 * src/main.c (main): Use lt_dlinsertsearchdir to prepend -M
3610 optargs to the existing libltdl search path.
3611 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.
3612 * m4/ltdl.c: Updated.
3614 * config/ltmain.sh: Ditto.
3616 2001-08-11 Gary V. Vaughan <gary@gnu.org>
3618 * src/main.c (main): Add `-b' (for `batch') mode switch to force
3619 interactive mode off.

3623 * configure.in: Require Autoconf 2.52.

3630 (M4_AC_FUNC_OBSTACK): Rename `m4_obstack' and `m4_obstack_h'.

3678 * TODO: Removed m4exit bug.
3679 * modules/load.c (m4_resident_module): Make this module resident.
3680 * module/m4.c (m4_resident_module): Ditto.
3681 * m4/modules.c (m4_module_load): Use new ltdl resident modules
3682 feature to mark modules as resident if they export
3683 `m4_resident_module' as TRUE.
3684 (m4_module_unload): Do not remove resident modules, and take care
3685 with symbol insertion and deletion with resident modules.
3686 * m4/ltdl.c, m4/ltdl.h: Update to latest unreleased versions to
3687 use resident modules feature.
3689 2000-11-30 Gary V. Vaughan <gary@gnu.org>
3691 * TODO: Updated. Removed some cruft that has since been fixed
3692 or implemented. Added some more entries.
3695 * modules/README: Updated.
3696 * doc/m4.texinfo: Updated.
3698 * modules/gnu.c (builtin_functions): Make indir orthogonal to
3699 builtin, in that each is recognised as a macro only with parameters
3700 (builtin_indir): Passing 0 arguments is now an error, as with
3703 * src/main.c (usage): Added missing description of `-c' option.
3705 2000-11-29 Gary V. Vaughan <gary@gnu.org>
3707 Consolidate the myriad of dispersed test scripts into the
3708 tests subdirectory. I think I now have all the file where I
3709 want them, so there shouldn't be anymore upheaval =)O|

3750 Move the implementation of GMP support for the mpeval() builtin
3751 into a loadable module that depends on libgmp. mpeval() and
3752 eval() share a common parser, now in m4/evalparser.c; the code
3753 in m4/numb.c and m4/numb.h is now physically split between
3754 m4/eval.c (the eval() backend) and modules/mpeval.c (the
3755 mpeval() backend), rather than being differentiated by cpp
3756 macros and multiple inclusion. The mpeval module is always
3757 built but will generate an diagnostic if it is used from an
3758 installation that didn't link in the gmp library.
3759 * modules/Makefile.am: build and install the new mpeval module.
3760 * modules/mpeval.c: Now contains the former parts of m4/numb.c
3761 and m4/numb.h that are required for gmp support in mpeval().
3762 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
3763 * m4/evalmp.c: Removed.
3764 * m4/m4module.h: Removed conditional prototype for
3766 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
3767 and m4/numb.h that do not rely on gmp.
3768 * m4/evalparse.c: New file, contains the shared parts of the
3769 eval() and evalmp() parser implementations, and is no longer
3770 unencumbered by cpp magic to uncover the right parts.
3771 * m4/numb.h: Removed. It's former contents are split between
3772 m4/eval.c and modules/mpeval.c.
3775 * tests/other-tests/changeword.test: New test. Rudimentary
3776 testing of changeword builtin runs only if --wnable-changeword
3777 was used at configure time.
3778 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
3779 alternation correctly. Split into two expressions to compensate.
3780 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
3781 * modules/Makefile.am: Build changeword module.
3782 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
3783 only when --enable-changeword was passed to configure.
3784 (builtin_changeword): If --enable-changeword was not used, then
3785 report that changeword() builtin has no support in m4 binary.
3787 2000-11-28 Gary V. Vaughan <gary@gnu.org>
3789 * src/main.c (main): Fixed a particularly nasty bug is
3790 user_search_path setting -- the -M flag processing must be
3791 extremely careful with search path ordering, or else the default
3792 installed module directory (possibly containing modules from a
3793 previous release) is placed earlier in the search path than any -M
3794 arguments (which are relied upon to load uninstalled modules with
3795 most of the tests in the regresion suite).
3797 * modules/load.c (builtin_load): Nasty hack to prevent adding
3798 symbols to symtab again if a module is loaded more than once.
3799 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
3801 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
3802 possible NULL pointer dereference.
3804 * m4/module.c (m4_module_find_by_modname): Renamed from
3805 m4_module_modname_find. Fixed all references.
3806 (m4_module_find_by_builtin): New function.
3808 * modules/modfreeze.test: load the `load' module with each
3810 * src/freeze.c (produce_frozen_state): Simplified in light of
3811 module field in m4_symbol. Allow a third argument for text macros
3812 to name the originating module.
3813 (reload_frozen_state): ditto.
3814 * m4/m4module.h: Fixup prototypes.
3815 * m4/builtin.h (m4_builtin_define): Add a module argument so
3816 that symbols can be registered against the defining module.
3817 (m4_macro_define): ditto.
3818 * m4/m4private.h (m4_symbol): Make the module field const to save
3819 on casting in the rest of the code.
3820 (SYMBOL_MODULE): New macro.
3822 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
3823 symbol reference maintenance bugs when removing a symbol from the
3826 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
3828 2000-11-27 Gary V. Vaughan <gary@gnu.org>
3830 * configure.in (m4_cv_func_obstack): A better check for whether
3831 libc has an obstack implementation.
3832 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
3834 * configure.in (--with-modules): Changed semantics. This
3835 option is now used to list modules to be preopened.
3836 * src/m4.h: #include "ltdl.h" unconditionally.
3837 * src/main.c: Removed all dependencies on WITH_MODULES.
3838 * src/freeze.c: ditto.
3839 * modules/Makefile.am: ditto.
3840 * m4/m4.c (builtin_m4exit): ditto.
3841 * modules/modpath1.test: ditto.
3842 * modules/modpath2.test: ditto.
3843 * modules/modpath3.test: ditto.
3844 * modules/modpath4.test: ditto.

3846 * modules/shadow.test: ditto.
3847 * modules/unload.test: ditto.
3849 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
3850 comes up on demand in LTLIBOBJS now.
3851 * configure.in (getopt_long): Creating and relying on a link for
3852 getopt.h on hosts with no getopt_long() of thier own works
3853 correctly now. This is necessary so that callers of getopt_long()
3854 can simply `#include <getopt.h>': the naive way of doing this
3855 would end up using our own getopt.h and the installed
3856 getopt_long(), which is asking for trouble!
3857 (obstack_init): A similar argument applies to obstack.h and
3860 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
3861 On Solaris-2.5 (at least) the native dlopen implementation
3862 gets confused about m4.o when looking for module "m4". This
3863 version always looks for .la an .$lib_ext suffixed names first
3864 to work around the problem. Sigh.
3866 * po/POTFILES.in: Take account of these file movements.
3867 * src/Makefile.am (m4_SOURCES): removed eval.c.
3868 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
3869 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
3870 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
3871 * modules/m4.c (builtin_eval): Use m4_evaluate().
3872 * m4/eval.c: Moved here from src/eval.c to facilitate
3873 implementation of eval() builtin as part of the `m4' loadable
3875 (m4_evaluate): renamed from evaluate for namespace cleanliness.
3876 * m4/numb.c: Moved here from src/numb.c, since it is #included
3877 into eval.c at compile time.
3878 * m4/m4module.h (m4_evaluate): Added prototype.
3879 * src/m4.h (evaluate): Removed prototype.
3881 2000-11-25 Gary V. Vaughan <gary@gnu.org>
3883 * modules/perl.c (builtin_perleval): Use PL_na for
3884 compatibility with perl-5.6.
3886 * src/main.c (main): It is now safe to
3887 ``m4_module_install("m4")'', without tripping over the m4
3889 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
3890 versions having fixed the insidious module search order bug.
3892 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
3893 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
3895 * configure.in: Figure out whether to use the installed
3896 getopt.h or the supplied one.
3897 * src/Makefile.am: ditto.
3899 * po/POTFILES.in: List files in their new positions.
3901 * config/ltmain.sh: This needs to be checked in to match the
3902 libtool macros copied to acinclude.m4 (until a released
3903 libtool copes with m4's needs).
3904 * bootstrap: Run gettextize.
3906 2000-11-24 Gary V. Vaughan <gary@gnu.org>
3908 * AUTHORS: Added my details.
3911 * bootstrap: temporary update until released libtool catches up.
3913 * All files: Use new GNU GPL copyright blurb with current contact
3916 * configure.in (LTLIBOBJS): Use canonical code for calculation of

3947 * modules/gnu.c: New file implementing a new loadable module wuth
3948 definitions for all the gnu extension builtins.
3949 * modules/format.c: Moved here from src/format.c. Now included
3952 * src/main.c (main): Load the traditional module if m4 was
3953 started in `no_gnu_extensions' mode.
3954 * modules/traditional.c: New file implementing the ``unix'' macro,
3955 required when m4 is executed in traditional mode, as a loadable
3958 * src/main.c: Renamed from m4.c to avoid confusion with
3960 (main): Always load the m4 module.
3961 * modules/m4.c: New file implementing a new loadable module with
3962 definitions for all m4 builtins that are not gnu extensions.
3964 * m4/Makefile.am: Adjusted to take new files below into account.

3968 the migration of all builtin implementations to loadable modules.
3969 * m4/macro.c: Moved this file here from the src directory,
3970 renaming all exported symbols to use the prefix ``m4_''.
3971 * m4/builtin.c: ditto.
3972 * m4/module.c: ditto.
3973 * m4/symtab.c: ditto.
3974 * m4/debug.c: ditto.
3975 * m4/input.c: ditto.
3976 * m4/output.c: ditto.
3978 * m4/ltdl.h, m4/ltdl.c: ditto.
3979 * m4/utility.c: Odd functions moved here from files in the src
3980 directory to facilitate builtin migration.
3982 2000-08-12 Gary V. Vaughan <gary@gnu.org>
3984 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
3985 error message, to make translators' jobs a little easier.
3986 (builtin_builtin): ditto.
3987 (builtin_traceon): ditto.
3988 (builtin_traceoff): ditto.
3989 Reported by Akim Demaille <akim@epita.fr>
3991 * m4/Makefile.am (pkgincdir): Deleted. Use automake's built in
3992 pkgincludedir instead.

4015 makeinfo calculates them for us, and to make any future
4016 reorganisation easier.
4017 (Frozen files): Document format version 2.
4018 `V' now takes argument `2'.
4019 `F' can take a single argument if symbol and builtin names
4020 are the same, or 3 arguments if the builtin is from a module.

4158 * src/m4.c (main): Assume interactive mode if STDIN is connected
4160 Changed startup sequence slightly so that syntax is not
4161 initialised from here when loading a frozen file.
4163 * src/builtin.c: Much improved macro definition style.
4164 * src/m4private.h: Internal structures for m4_builtin and

4170 (make_builtin_table): Build an internal builtin table from an
4171 external definition.
4173 * src/module.c (module_unload): Be extremely careful to remove
4174 builtins and macros that match the module being unloaded -- no
4175 longer assume that the top element can be removed incase another
4176 odule defines an identical name.
4177 * src/symtab.c (remove_table_reference_symbols): remove all symbol
4178 table entries which refer to a given builtin table.
4179 * src/builtin.c (remove_tables): Use it!
4181 2000-07-13 Thomas Tanner <tanner@ffii.org>
4183 * Makefile.am (SUBDIRS): we need modules/ for "make dist"
4184 * acm4/modules.m4: deleted
4185 * bootstrap: don't libtoolize libltdl!
4186 * configure.in: AC_SUBST INCLTDL and LIBLTDL, -with-modules flag:
4187 if set, enable WITH_MODULES and add modules to DLPREOPEN
4188 * examples/misc.test: redirect standard output
4189 * lib/Makefile.am: don't use DLLDFLAGS
4190 * lib/m4module.c: include necessary headers to silence GCC -Wall

4201 LTDL_SET_PRELOADED_SYMBOLS
4202 * src/module.c: libltdl's memory management must be initialized
4203 before calling lt_dlinit!, fix warnings
4205 2000-01-18 Gary V. Vaughan <gary@gnu.org>
4207 * README: Caveat about nls not supported by dll architecture on
4210 * TODO (MODULE SPECIFIC ISSUES): more ideas for the future.

4214 * modules/Makefile.am (LIBS): ditto.
4215 (INCLUDES): search $(top_srcdir) (for eg. <m4/error.h>) and then
4216 $(top_srcdir)/m4 (for only <m4module.h>).

4231 * acm4/ltdl.m4: Updated to latest from libtool cvs.
4232 * acm4/modules.m4: Remove code which duplicates ltdl.m4 and
4233 increment serial number.
4235 * Makefile.am (SUBDIRS): Moved @MODULES_DIR@ to compile before
4236 src dir and immediately after libm4 is built for confidence that
4237 it doesn't rely on the src directory.
4238 (SUBDIRS): Moved doc dir to the end since helptoman.pl and
4239 makeinfo stop the build on cygwin (because they don't work).
4241 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
4243 * m4/m4private.h: ...is not a public header, so moved to src.
4244 Add `#include <config.h>', `#define _COMPILING_M4' and
4246 * m4/Makefile.am (noinst_HEADERS): remove m4private.h.
4247 * src/Makefile.am (noinst_HEADERS): add m4private.h.

4267 (INCLUDES): Look first in $(top_srcdir) (for eg. <m4/error.h>),
4268 and then in $(top_srcdir)/lib (for eg. "m4private.h").
4269 * src/Makefile.am (m4_LDADD): replace libi/libm4.la with
4271 * m4/m4error.h: Renamed error.h, for installation to
4272 $prefix/include/m4..

4287 From Akim Demaille <akim@epita.fr>
4289 2000-01-17 Gary V. Vaughan <gary@gnu.org>
4291 * src/ltdl.c: Use access() to abort doomed module load attempts
4292 if module file does not exist.
4294 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
4295 getopt1.o will already be used if appropriate, so I moved getopt.c
4296 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
4298 * modules/modpath1.test: Use correct filename in header line.
4299 * modules/modpath2.test: ditto.
4300 * modules/modpath3.test: ditto.
4301 * modules/modpath4.test: ditto.
4303 Without these changes lt_dlopen("test") attempts to
4304 LoadLibrary("/bin/test") on Windows, which although harmless
4305 generates a spurious error message which spoils most of the tests:
4306 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
4307 (TESTS): s/test.test /modtest.test /
4308 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /
4309 (test_la_SOURCES, test_la_LDFLAGS): renamed to use modtest.
4310 * modules/modpath1.test: s/test.m4 /modtest.m4 /
4311 * modules/modpath2.test: ditto.
4312 * modules/modpath4.test: ditto.
4313 * modules/modpath3.test: s/-m test /-m modtest /
4314 * modules/shadow.m4: use {un,}loadmodule(`modtest').
4316 2000-01-16 Gary V. Vaughan <gary@gnu.org>
4318 * src/ltdl.c (find_file): Updated to new version with fixed memory
4319 allocation bug in `next'.
4320 * src/ltdl.h: updated to match.
4322 * modules/Makefile.am: Cleaned up and reordered.
4324 2000-01-16 René Seindal <rene@seindal.dk>
4326 * modules/Makefile.am (TESTS): New tests for the module system.
4328 * modules/*.test: New files.
4330 * src/m4.c (main): Added call to module_init().
4331 Treats -M and -m as the arguments -D -U and -t, ie deferred.
4333 * src/m4.h: Added declaration of module_init().
4335 * src/module.c (module_init): No longer static
4337 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
4338 Added to shut up automake about non standard libtool library
4341 * src/module.c: Disabled DEBUG by default.
4343 * modules/README: Changed example from unload.m4 to shadow.m4
4345 * modules/shadow.m4: Renamed from unload.m4
4347 * modules/Makefile.am (EXTRA_DIST): Removed unload.m4.

4352 2000-01-12 Gary V. Vaughan <gary@gnu.org>
4354 * doc/help2man.pl: updated to version 1.020.
4356 * lib/COPYING.LIB: updated to version 2.1.
4358 * lib/m4module.h: restructure the M4_SCOPE code to work when
4359 creating a dll which links with libm4.la and both DLL_EXPORT
4360 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
4363 2000-01-11 Gary V. Vaughan <gary@gnu.org>
4365 Merged the following changes from my tree:
4367 1999-06-15 Gary V. Vaughan <gary@gnu.org>
4369 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
4370 ported to compile shared libs.
4372 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
4373 use `__declspec(dllimport)' when linking libm4.la on win32.
4374 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
4376 * configure.in (M4OBJS): Discover whether we need the shipped
4377 implementation of getopt_long.
4378 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
4379 main binary here, as opposed to the module library in lib/libm4.la.
4381 1999-06-14 Gary V. Vaughan <gary@gnu.org>
4383 * modules/README: Updated to describe the improved libltdl based
4385 * README (cygwin): Added some compilation notes for building m4
4386 correctly under cygwin.
4387 * TODO: Cleaned out the entries for the module system since they
4388 are now implemented.
4390 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
4391 all instances of __P with M4_PARAMS.
4393 * lib/getdate.h: removed unreferenced file.
4395 * lib/m4private.h: New file to define the private interface to the
4396 token_data struct, which must be shared between m4module.c, and
4397 builtin.c but not exported to modules built from the installed
4398 m4module.h since it's size changes depending on compile time
4401 * src/m4.h: Lots of stuff moved to lib/m4module.h.
4403 * lib/m4module.h: New file to define the interface available when
4404 compiling m4 modules.
4405 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
4406 necessary for module compilation into this new file.
4408 * lib/Makefile.am (include_HEADERS): install headers (renamed to
4409 avoid nameclash with other system headers) necessary for compiling
4411 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
4412 so that modules can include the (renamed) installed headers and
4413 be guaranteed a matching implementation.
4414 * lib/m4error.h: renamed from error.h.
4415 * lib/m4obstack.h: renamed from obstack.h.
4416 * lib/m4regex.h: renamed from regex.h.
4417 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
4418 implementation, simply include the shipped version
4419 unconditionally, otherwise it is hard for a module to know
4420 whether the m4obstack.h header it is using matches the
4421 implementation it ends up linking against.
4422 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
4425 1999-05-18 Gary V. Vaughan <gary@gnu.org>
4427 * examples/misc.test: Don't run this test on machines which don't
4428 have a root user in /etc/passwd (e.g. cygwin).
4430 * tests/get-them (/^@example$/): Error messages might have a
4431 ``.exe'' suffix to the program name, or else use the libtool
4432 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
4433 of these cases are now catered for when comparing error messages
4435 * tests/other-tests/*.test: ditto.
4436 * examples/*.test: ditto.
4438 * tests/defs (M4): use libtool execute mode.
4439 * examples/defs (M4): ditto.
4441 * tests/get-them (END): explicitly close any open file.
4442 (printthem): In a regular expression, '{' is the start of a repeat
4443 count! Use `[{]' for a literal open brace.
4444 (/^@node /): Don't use substr on a string shorter than the trim
4447 1999-05-17 Gary V. Vaughan <gary@gnu.org>
4449 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
4451 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
4453 2000-01-10 Andreas Schwab <schwab@suse.de>
4455 * tests/other-tests/gmp.test: Find config.sh in build directory.
4457 * configure.in: Find tests/mkconfig.sh in $srcdir.
4459 * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in
4460 <signal.h> (for SUS2 compliant systems).
4462 * src/stackovf.c: Check for HAVE_SIGINFO_T in addition to
4465 2000-01-10 René Seindal <rene@seindal.dk>
4469 * TODO, NEWS: Cleaned up and updated.
4471 * src/m4.c (main): New variable exit_status for exit status in
4472 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
4473 file cannot be read instead of EXIT_SUCCESS.
4475 * src/builtin.c (m4_indir): Changed error message to help
4476 translators (from Akim Demaille <demaille@inf.enst.fr>).
4478 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
4481 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
4484 * src/input.c (match_input): Reordering of code, to avoid multiple
4485 calls to push_string_init() from obstack_grow(), which can happen
4486 with some compilers (found and fixed by James Bonfield
4487 <jkb@mrc-lmb.cam.ac.uk>).
4489 * src/stackovf.c: Added prototypes for ultrix.
4490 (setup_stackovf_trap): Added __P to cast.
4491 (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>)
4493 2000-01-09 René Seindal <rene@seindal.dk>
4495 * doc/m4.texinfo (Changequote): Added comment about changing
4496 quotes when the old quote is a part of the new.
4498 * src/builtin.c (expand_ranges): Added break after trailing dash.
4499 This caused misbehavious on some systems (found and fixed by Akim
4500 Demaille <demaille@inf.enst.fr>).
4502 * AUTHORS: Thomas Tanner included
4504 * acconfig.h: Added entry for ss_sp (see below).
4506 * configure.in (use_stackovf): Added check for stack_t with member
4507 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert
4508 <eggert@twinsun.com>).
4510 * doc/m4.texinfo (Frozen files): Added a simpler example for
4511 generating frozen files from several input files.
4513 1999-11-14 Paul Eggert <eggert@twinsun.com>
4515 * po/POTFILES.in: Add lib/getopt.c, lib/obstack.c,
4516 lib/regex.c, lib/xmalloc.c.
4518 1999-11-10 René Seindal <rene@seindal.dk>
4520 * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal.
4522 * src/module.c: reindented.
4523 (module_load): return if this is a repeated load of same module.
4524 (module_init): slight change of logic to avoid repeated
4525 initialisation debug messages.
4527 * Makefile.am (DIST_SUBDIRS): Added to ensure modules/ is included
4528 in the distribution.

4533 (stdlib_la_LDFLAGS): ditto
4535 1999-11-10 Paul Eggert <eggert@twinsun.com>
4537 * src/m4.h: Include error.h, since our macros use error.
4538 * src/m4.c: Don't need to include error.h.
4540 1999-11-09 Paul Eggert <eggert@twinsun.com>
4542 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
4543 and zero, as Solaris 7 cc does.
4544 (bcopy): Remove macro; no longer needed with new obstack.h.
4546 * src/output.c (freeze_diversions): Don't assume that a
4547 diversion size can fit in `int'. Check for diversion file
4548 size too large to be printed with `unsigned long'.

4552 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.
4554 * src/debug.c (trace_format):

4568 * src/module.c: entirely new implementation using libltdl.
4569 * po/POTFILES.in: added src/module.c.
4570 * modules/Makefile.am (LTLIBRARIES): Removed lib prefix as these
4571 are modules, not linktime libraries.
4572 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
4573 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
4574 avoidance on exported symbols.
4575 * modules/test.c (m4_macro_table, m4_init_module,
4576 m4_finish_module): ditto.
4577 * modules/time.c (m4_macro_table): ditto.
4579 * modules/time2.m4: new file which requires command line loading
4581 * src/m4.c (--load-module): dynamically load named runtime module
4582 into running executable before reading the source.
4583 (--module-directory): prepend a directory to the module search
4585 (module_init()): Do this the first time we load a module instead;
4586 if the module subsystem is broken normal m4 scripts can still run.
4587 * src/m4.h (install_builtin_table): is now exported.
4589 1999-03-26 Gary V. Vaughan <gary@gnu.org>
4591 * src/module.c: removed. No longer required.

4602 * src/Makefile.am (MAINTAINERCLEANFILES): ditto.
4603 * tests/Makefile.am (MAINTAINERCLEANFILES): ditto.

4607 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
4608 * acm4/gettext.m4: removed. It causes a multiple definition vs.
4609 the installed gettext.m4 file when running aclocal.
4611 1999-03-25 Gary V. Vaughan <gary@gnu.org>
4613 * configure.in (AM_INIT_AUTOMAKE): bumped version number to

4615 (AC_LIBLTDL_CONVENIENCE): build libltdl as a convenience library
4616 in its own subdirectory.
4618 * modules/Makefile.am (*_SOURCES): renamed to use libtool's "no
4619 lib prefix on a module" feature.
4620 (LDFLAGS): Added `-module -avoid-version' flags to build
4621 versionless module libraries.
4622 * src/builtin.c (m4_load_module): use libltdl.
4623 (module_unload_all): use libltdl.
4624 * src/m4.c (module_init): initialise module loading on demand for
4625 better diagnostics, and so that m4 will still work even if
4626 the module code is broken.
4627 * src/m4.h (module_init): removed. No longer relevant.
4628 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on
4629 exported symbols for compatibility with dlpreopening.
4630 * modules/test.c (m4_macro_table, m4_init_module,
4631 m4_finish_module): ditto.
4632 * modules/time.c (m4_macro_table): ditto.
4634 * bootstrap: New file. Runs all the autoutils in the right order
4635 after a fresh checkout, or a make maintainer-clean.
4637 1999-02-18 Akim Demaille <demaille@inf.enst.fr>
4639 * src/builtin.c (dump_symbols): New function, factoring common
4640 content of m4_dumpdef and m4_symbols.
4641 (m4_dumpdef): Use it.
4642 (m4_symbols): New function, implementing `symbols'. Use it.
4643 * doc/m4.texinfo: Fixed missing commas after @xref, so that the
4644 file compile with modern makeinfo.
4645 (Symbols): New node, documenting symbols.
4646 (direntry): Modernize.
4648 1998-12-11 René Seindal <rene@seindal.dk>
4650 * src/builtin.c (predefined_tab): New predefined macros
4651 __m4_changeword__, __m4_gmp__ and __m4_modules__ for testing for
4652 configure time options.
4654 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
4656 * src/module.c (module_try_load): Don't try to be clever and
4657 overwrite argument string. Instead allocate all constructed
4658 strings locally, since they can have arbitrary lengths. Make
4659 arguments pointers to const.
4660 (module_search): Simplify due to above change.
4662 1998-11-29 René Seindal <rene@seindal.dk>
4666 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): New tests.
4668 * tests/other-tests/import-environment.{m4,test}: New test.

4693 * When configured with --with-gmp both the normal (fast) eval()
4694 and the gmp aware mpeval() are defined. To restore previous
4695 bahaviour use "define(`eval', defn(`mpeval'))".
4697 * tests/other-tests/gmp.m4: Changed to use mpeval().
4699 * src/evalmp.c: New file for compiling eval.c as gmp aware.
4700 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
4702 * src/eval.c: Now includes "numb.c" directly. Everything in this
4703 file must by static, except evaluate(), which is changed to
4704 mp_evaluate() if USE_GMP in force.
4706 * src/numb.c: Changed to be included by eval.c instead of being
4707 compiled separately. Everything is declared static.
4709 * src/numb.h: Removed declarations of functions, as numb.c is now

4725 1998-11-27 René Seindal <rene@seindal.dk>
4727 * Error messages now always print program name before input file
4728 name as specified by GNU coding standards. Reported by Akim
4729 Demaille <demaille@inf.enst.fr>.
4731 * doc/m4.texinfo (Include): Change due to changed error message
4735 * tests/get-them: Minor change to sed script due to changed error
4738 * src/m4.c (print_program_name): New func used to print program
4739 name, input file and line number in error (). Used as an
4740 error_print_progname handler.

4751 warning of ambiguous 'else'.
4753 * src/module.c: Inserted search path code from path.c modified to
4755 (module_init): Configured default path used only if M4MODPATH is
4757 (module_try_load): Now reads libMODULE.la as generated by libtool
4758 for actual module name.
4759 (module_load): Gives better error messages on failure.

4765 functions of more generic search path handling.
4767 1998-11-24 René Seindal <rene@seindal.dk>
4769 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
4770 included gettext, as <libintl.h> might not be found
4771 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
4773 1998-11-22 René Seindal <rene@seindal.dk>
4775 * src/output.c (insert_diversion): Fixed bug that might cause m4
4776 to read from standard output! Triggered by input
4777 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
4778 so now 'undivert(0)' does nothing.
4780 1998-11-18 René Seindal <rene@seindal.dk>
4784 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
4785 could be changed when compiling a illegal regexp, causing later
4786 use of the regexp to dump core.
4788 * src/module.c (module_load): Changed error message to conform to
4791 * src/m4.c (usage): Added message about reporting bugs.

4806 renamed when installed.
4808 * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
4809 USE_SHL_LOAD to HAVE_SHL_LOAD
4811 * src/builtin.c (shipout_string): Now tests for a NULL string.

4827 getpwuid, hostname, rand, srand, getenv, setenv, unsetenv, uname.
4829 * src/builtin.c (shipout_string): New convenience function for
4830 builtins and modules.

4841 These two are now initialised by autoconf macros.
4843 * src/path.c (module_env_init): MODULE_PATH is always on the
4846 * src/Makefile.am: Now generated pathconf.h which defined the
4847 default MODULE_PATH.
4849 * configure.in (pkglibexecdir): Added defintion of pkglibexecdir,
4850 where modules are installed.
4852 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
4853 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
4854 build and install automatically, and it is prepared for other
4855 interfacec than dlopen().
4857 * src/builtin.c (predefined_tab): Added __m4_version__ for the
4858 current version of GNU m4. It is a GNU extension.
4860 1998-11-14 René Seindal <rene@seindal.dk>

4893 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): Added manually
4894 maintained tests in tests/other-tests. These currently tests for
4895 8-bit transparency, multiple precision arithmetic and sync-line

4938 1998-10-07 René Seindal <rene@seindal.dk>
4942 * tests/Makefile.am (GENERATED_TESTS): Changed .m4 extension to
4943 .test, as the files are no longer just m4 input.
4945 * tests/get-them (FILE): Changed .m4 extension to .test.

4952 (expand_argument): Do.
4954 * src/input.c (next_token): SPACE and NUM/OTHER characters are only
4955 grouped together iff both quote and comment strings are single
4956 character. Otherwise they might include a comment/quote leader.
4957 (next_token): Returns new token type TOKEN_SPACE.
4959 * src/builtin.c (push_builtin_table): New function to push a
4960 builtin_table on the stack without installing its contents.
4961 (find_builtin_by_name): Added call to push_builtin_table() if

4966 1998-10-04 René Seindal <rene@seindal.dk>
4970 * configure.in (ALL_LINGUAS): Added Polish pl.po
4972 1998-10-03 René Seindal <rene@seindal.dk>

4984 skip_space, bad_argc), and the macros ARG() and DECLARE().
4986 * src/builtin.c (install_builtin_table): New function. Each
4987 module brings in a builtin_table, which is pushed on a stack.
4988 (struct builtin_table): New struct for list of builtin_tables.
4989 (m4_loadmodule): New function to implement builtin "loadmodule".
4990 (shipout_int): No longer static, to be used by modules.

5011 * configure.in: Added modules/Makefile to AC_OUTPUT.
5013 * configure.in: Added code to implement --with-modules. Tests for
5016 * acconfig.h: Added WITH_MODULES
5018 1998-10-02 René Seindal <rene@seindal.dk>
5020 * examples/Makefile.am (pkgdata_DATA): Removed special target for
5021 check and variables TESTS. These tests are now run from the
5024 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
5025 directory. The files stay there but the tests are run from the
5028 * tests/Makefile.am (EXTRA_DIST): Added run-test.
5030 * tests/run-test: New file. Run a test manually
5032 * tests/Makefile.am, tests/get_them: Moved automatically generated
5033 tests (from the manual) to sub directory tests/gentest/. The
5034 tests/ directory had gotten a bit messy.
5036 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
5038 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\

5056 * Makefile.am (SUBDIRS): Removed checks directory
5057 * configure.in (AC_OUTPUT): Removed checks/Makefile
5059 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
5060 the space when m4.texinfo is edited and whitespace.el is active.
5061 (Defn,example): idem.
5063 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
5065 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
5066 ../COPYING. ../Makefile is a file which is certainly present when
5067 test is executed in testSubDir. One can't be sure that the COPYING
5068 file is in .. or ../.. in all situations, the ../Makefile is
5071 * doc/m4.texinfo (Include): adjusted expected test output
5072 according to new tests, i.e. the input will always come from the
5073 file `in' created by the test.
5075 * tests/Makefile.am: Added three lines at the top to get
5076 esyscmd.1.test working.
5078 * tests/get-them: modified to generate clearer tests who will need
5079 less maintenance when new test examples are created in
5080 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
5081 need the generic file `defs') shell scripts creating `in', `ok',
5082 `out' and when apropriate `okerr' and `err' in the directory
5083 `testSubDir' when executed. The compare of `ok' and `out'
5084 (and of `okerr' and `err') will be the exit status of the test.
5085 `out' must match `ok' (and `okerr' must match `err') for the test
5088 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
5089 the tests generated by tests/get-them getting it input normally
5090 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
5091 (dot) before the numeric part) is reserved for all other (hand
5092 written) tests. The `+' means one or more times.
5094 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
5096 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to

5124 "changesyntax" to modify the syntax table.
5126 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax
5127 table. All categories are assigned a syntax code and tokens are

5130 1998-08-09 René Seindal <rene@seindal.dk>
5132 * src/numb.{c,h}: New files, implements multiple precision eval
5133 using GNU gmp. Originally submitted by John Gerard Makecki

5145 of comment and quote strings to `unsigned int' to allow eight bit
5146 chars (reported by andrewb@zip.com.au (Andrew Bettison)).

5161 and _ macro. M4 now builds with --disable-nls.
5163 * src/m4.c (main): reintroduced textdomain(PACKAGE) to get gettext
5164 to look for right message catalogs. Call indef'ed by ENABLE_NLS.
5166 * configure.in (ALL_LINGUAS): Added complete list of translations:

5271 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
5272 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
5273 defines __STDC__ to 0, for indicating it is *not* ANSI!
5274 Reported by Kaveh R. Ghazi.
5276 * configure.in: Added obsolescent tests for AIX and Minix.
5278 * doc/Makefile.in (mostlyclean): Remove texclean in dependencies,

5285 * aclocal.m4 (fp_C_PROTOTYPES): Force -D_HPUX_SOURCE with -Aa.
5286 Reported by John David Anglin.
5288 * src/ansi2knr.c: New version, sent by Peter Deutsch.
5289 * aclocal.m4 (fp_C_PROTOTYPES): Substitute empty or ansi2knr for
5290 ANSI2KNR, depending on the fact the compiler is ANSI or not.
5291 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
5292 Remove the sed filter after ansi2knr for debug.c. Use $O instead
5293 of $U, put underline in extensions rather than in basenames. Use
5294 implicit rules, now that regularity makes this possible.
5295 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
5296 of ansi2knr whenever it is needed.
5297 * configure.in: Adjusted for correct STACKOVF substitution.
5298 * src/debug.c (trace_format): When not __STDC__, use (...) as a
5299 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.
5300 Reported by David MacKenzie.
5302 * Makefile.in: Remove binprefix. Use transform_name instead.
5303 Reported by David MacKenzie.
5305 * doc/Makefile.in: Create version.texi, use it, clean it.

5310 * Makefile.in (all, install, uninstall): Depend on Makefile.
5312 * Makefile.in: For actions invoking $(MAKE) from within compound
5313 sh statements, exit non-zero if the sub-make fails. Otherwise,
5314 the top-level make may exit successfully when it should fail.
5315 Reported by Jim Kingdon.
5317 * {,/*}Makefile.in: Use && after all cd, in case they fail.
5319 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.
5320 (dist): Use PRODUCT and VERSION instead of tricks on .fname.
5321 * configure.in: Substitute PRODUCT and VERSION.
5323 * {,*/}Makefile.in (dist): Always try a hard link before a copy.
5325 1994-10-27 François Pinard <pinard@iro.umontreal.ca>

5341 1994-10-01 François Pinard <pinard@iro.umontreal.ca>
5343 * configure.in: Do not add -O to CFLAGS for GNU C, now that
5344 configure does it automatically.
5345 Reported by Jim Meyering.
5347 1994-09-23 François Pinard <pinard@iro.umontreal.ca>
5349 * src/stackovf.c: Declare the handler_t typedef earlier in the
5350 code, use it for stackovf_handler.
5351 (setup_stackovf_trap): Use RETSIGTYPE instead of void while
5352 casting sigsegv_handler.
5353 Reported by Robert Bernstein.
5355 * src/m4.c (main): Initialize program_name to argv[0] without
5357 Reported by Karl Berry.

5362 Reported by Karl Berry.
5364 1994-09-14 François Pinard <pinard@iro.umontreal.ca>
5366 * lib/Makefile.in (mostlyclean): Added.
5367 (TAGS): Make in $(srcdir).
5369 * configure.in: Use `choke me' in test, like everywhere!
5371 * {doc,examples,lib,src}/Makefile.in (check): Deleted, as
5372 unreacheable and useless.
5374 * doc/Makefile.in (texclean): Deleted, merged in mostlyclean.

5377 (distclean): Do not remove TAGS.
5378 (realclean): Remove it.
5379 * Makefile.in: Make TAGS in lib also, not just in src.
5380 Reported by Karl Berry.
5382 * Makefile.in (distclean, realclean): Instead of recursively
5383 calling $(MAKE) for the -local part, allow parallel execution of
5384 -recursive and -local, only delay the removal of config.status,
5385 which is repeated in both goals.
5387 1994-09-13 François Pinard <pinard@iro.umontreal.ca>
5391 * Makefile.in: Group all *clean-recursive goals in one, using sed
5392 to remove `-recursive' while calling make recursively. Also, use
5393 a subshell for each recursive $(MAKE).
5394 Reported by Jim Meyering.
5396 * src/m4.h (memcpy): Define with bcopy for BSD systems.
5397 Reported by Kaveh R. Ghazi.
5399 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
5400 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
5403 * configure.in: Use date instead of touch for stamp-h.
5404 * Makefile.in (stamp-h.in): Idem.
5406 * Makefile.in (distclean, realclean): Force serial execution of
5407 both goals, in case parallel makes are being used.
5408 Reported by Jim Meyering.
5410 * src/Makefile.in (DISTFILES): Distribute TAGS.
5411 (distclean): Do not remove TAGS.
5412 (realclean): Remove it.
5413 Reported by Karl Berry.
5415 1994-09-10 François Pinard <pinard@iro.umontreal.ca>
5417 * configure.in: Use fp_ to match aclocal.m4. Revert _OS_ macros

5420 1994-09-08 François Pinard <pinard@iro.umontreal.ca>
5422 * Makefile.in (MDEFINES): Remove INSTALL substitutions, for
5423 ./install.sh will not be correctly referred to in sub-Makefiles.
5424 Reported by John David Anglin.
5426 * doc/Makefile.in (texclean): Remove *.cps and *.fns too.
5427 Reported by Eric Backus.
5429 * Makefile.in, checks/Makefile.in, doc/Makefile.in,
5430 examples/Makefile.in, lib/Makefile.in, src/Makefile.in: Limit
5431 config.status into remaking this directory's Makefile only.
5432 * Makefile.in (stamp-h): Do not check nor touch stamp-h.
5433 * configure.in (AC_OUTPUT): Touch stamp-h if CONFIG_HEADERS.
5434 Reported by Jim Meyering.
5436 1994-09-06 François Pinard <pinard@iro.umontreal.ca>
5438 * configure.in: Correct stack overflow detection logic, taking
5439 care of systems having only incomplete implementations (like for
5440 Pyramid 9820 OSx 5.0d).
5441 Reported by Kaveh R. Ghazi.
5443 * src/Makefile.in (TAGS): Remote -t from etags call.
5445 1994-09-02 François Pinard <pinard@iro.umontreal.ca>
5447 * lib/Makefile.in (install): Depend on all.
5449 1994-08-31 François Pinard <pinard@iro.umontreal.ca>

5452 Reported by Jim Meyering and John David Anglin.
5454 * Makefile.in (distclean-local): Delete config.log.
5455 Reported by Jim Meyering.
5457 Solidify frozen files with respect to -P:
5458 * src/m4.c: Have -P set prefix_all_buitins variable instead of
5459 calling a function by that name. Declare the variable.
5460 * src/m4.h: Adjust declaration for prefix_all_buitins.
5461 * src/builtin.c (builtin_init): Merge in functionality from
5462 previous prefix_all_buitins function, while making entries in the
5463 symbol table, but not modifying the builtin description itself.
5465 * src/freeze.c (reload_frozen_state): Add a useless `break;',
5466 because *many* compilers do not accept an empty `default:'.
5467 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
5468 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
5470 * configure.in: Use AC_TYPE_SIGNAL.
5471 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.
5472 Reported by Robert Bernstein.
5474 * checks/Makefile.in (check): Modify PATH so check-them will find
5475 m4 in the src directory.
5476 * Makefile.in (check): Don't.
5477 Reported by Akiko Matsushita and Jim Meyering.

5480 functions, for implementing a global MAXIMUM_TOTAL_SIZE instead of
5481 a per buffer MAXIMUM_BUFFER_SIZE.
5483 * src/output.c (output_text): New function, for optimizing the
5484 output of strings of characters. Use it.
5486 1994-08-30 François Pinard <pinard@iro.umontreal.ca>
5488 * doc, src: New directories reorganizing the distribution.
5489 * doc/Makefile.in, src/Makefile.in, examples/Makefile.in: New
5491 * Makefile.in: Adjusted.
5492 * configure.in: Configure new Makefiles.
5494 * m4.h: Declare STRING typedef. Use it for comment and quote
5495 strings, adjusting all references. (This is the rudiments of a
5496 beginning for the eventual withdrawal of NUL terminated strings.)
5497 * output.c (shipout_text): Accept a length parameter, and use it.
5498 All callers adjusted.
5500 1994-08-29 François Pinard <pinard@iro.umontreal.ca>
5502 * m4.h: Include <unistd.h> if it exists.

5515 (output_init): Allocate only diversion 0.
5516 (make_diversion): Allocate new diversions as needed.
5517 * m4.h, m4.c: Remove NDIVERSIONS and ndiversion related stuff.
5518 * m4.c: Still accept -N, but do nothing with it.
5519 Reported by David MacKenzie.
5522 * output.c (freeze_diversions): New function.
5523 * m4.h: Declare freeze_diversions.
5524 * freeze.c: Document frozen file format, revise it, call
5525 freeze_diversions to add diversions to frozen format, and code to
5526 reload them properly.
5527 * m4.c: Do not undivert automatically at end when status being
5528 frozen. Do not call builtin_init when reloading frozen state.
5530 Speed up diversion processing:
5531 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
5532 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
5533 structure and variables, cached variables out of output_diversion,
5534 reallocate_diversion_for and OUTPUT_CHARACTER.
5535 (shipout_text, make_diversion, insert_diversion): Adapted to new
5537 (insert_file): Use better buffering.
5538 Reported by David MacKenzie.
5540 1994-08-28 François Pinard <pinard@iro.umontreal.ca>
5542 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
5543 dist works from another build directory.
5545 1994-08-27 François Pinard <pinard@iro.umontreal.ca>
5547 * symtab.c (hack_all_symbols): Use hash_table_size instead of
5548 constant HASHMAX, for -H option to work better.
5550 * builtin.c (DECLARE): Simplify by using _ ().
5552 * freeze.c: New file.
5553 * Makefile.in: Compile it, distribute it.
5554 * m4.c: Recognize, document and process --freeze-state (-F) and
5555 --reload-state (-R) options. Pass a true flag to builtin_init
5556 only if no reloading some state.
5557 * builtin.c (define_builtin): Remove static specifier.
5558 (find_builtin_by_name): Remove static specifier.
5559 (builtin_init): Accept and obey a flag argument.

5562 1994-08-24 François Pinard <pinard@iro.umontreal.ca>
5564 * builtin.c (dumpdef_cmp): Rewrite so the cast protect the const
5567 * configure.in: Implement --with-dmalloc.
5568 * acconfig.h: Document WITH_DMALLOC.
5569 * m4.h: Add code for when WITH_DMALLOC.
5571 1994-08-15 François Pinard <pinard@iro.umontreal.ca>
5573 * m4.c (long_options): Use "error-output", the dash was missing.
5574 Reported by Akiko Matsushita.
5576 1994-08-12 François Pinard <pinard@iro.umontreal.ca>
5578 * m4.h: Include <sys/types.h>.
5579 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
5580 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
5582 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
5584 * builtin.c (dump_args): Declare len as size_t, not int.
5586 * debug.c: Prototype the forward declaration of debug_set_file.
5588 * builtin.c (m4_undivert): Replace div by file, for avoiding the
5589 shadowing of this variable.
5590 * output.c (insert_diversion): Idem.
5592 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
5593 (input_init): Duplicate default quote and comment strings.
5594 (set_quotes): Free previous quote strings in all cases. Duplicate
5595 even default quote strings.
5596 (set_comment): Free previous comment strings in all cases.
5597 Duplicate even default comment strings.
5599 * configure.in: Updated for Autoconf 2.0.
5600 * Makefile.in (distclean-local): Also delete config.cache.
5602 * m4.c (usage): Reorganize the --help output by topic. Include a
5603 description for debugging flags.
5605 1994-07-29 François Pinard <pinard@iro.umontreal.ca>
5607 * configure.in: If sigaction is available and SA_ONSTACK defined,
5608 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
5609 defined, use sigvec. Else don't compile stackovf.c.
5610 * stackovf.c (setup_stackovf_trap): Idem.
5611 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
5614 1994-07-21 François Pinard <pinard@iro.umontreal.ca>
5616 * m4.c (usage): Replace printf par fputs.
5618 1994-07-18 François Pinard <pinard@iro.umontreal.ca>
5622 1994-07-17 François Pinard <pinard@iro.umontreal.ca>
5624 * configure.in: Check for sigaction and sigvec. Add a new delayed
5625 check for RLIMIT_STACK, combine in the checking for getrlimit.
5626 All those things are not universally available.
5627 * stackovf.c: Split setting up the trap handler and catching
5628 signals, for better taking care of various configure outcomes.
5629 * examples/stackovf.sh: Correct a typo.
5630 Reported by Eric Backus, Jim Avera and Jim Meyering.
5632 1994-07-16 François Pinard <pinard@iro.umontreal.ca>
5634 * ansi2knr.c: New version sent by its author, Peter Deutsch.
5636 1994-07-15 François Pinard <pinard@iro.umontreal.ca>
5638 * Makefile.in: Modify so parallel make will not try making
5639 lib/libm4.a twice simultaneously.
5640 Reported by Jim Meyering.
5642 1994-07-14 François Pinard <pinard@iro.umontreal.ca>
5644 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
5645 error message, for when no code possibility exists. Even if this
5646 line is completely #ifdef'ed out, it brings a syntax error.
5647 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
5649 * Makefile.in (install): Have install depend on all too, for lib
5650 to be remade as needed.
5652 * examples/stackovf.sh: Try ksh, bsh and bash for shells
5653 providing ulimit, instead of using only ksh.
5654 Reported by Jim Avera and Joseph E. Sacco.
5656 1994-07-12 François Pinard <pinard@iro.umontreal.ca>
5658 * Makefile.in (check): Have it depend on all instead of m4. In
5659 this way, a change in lib will be detected and processed.
5661 * builtin.c (numeric_arg): Use strtol and verify the conversion,
5662 instead of using sscanf which stops as soon as there is a
5663 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
5664 and divert(1xyzzy) were all accepted without any warning or error
5666 * m4.h: Declare strtol as long if not including stdlib.h.
5667 * configure.in: Check for limits.h, and replace strtol if missing.
5668 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
5669 * lib/strtol.c: New file, from elsewhere.
5670 Reported by Andreas Schwab.
5672 1994-07-07 François Pinard <pinard@iro.umontreal.ca>
5674 * macro.c (expand_macro): Cast value to (boolean) prior to
5675 assigning it to traced.
5676 Reported by Tom McConnell.
5678 * Makefile.in (m4): Always make all in lib first.
5679 Reported by Jim Meyering.
5681 1994-07-06 Jim Avera <jima@netcom.com>
5683 * stackovf.c: Isolated OS-dependent sections; Improved portability,
5684 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
5685 handlers), and a default error message if the fault address is not
5686 available (when neither siginfo.h nor BSD sigcontext are supported).
5687 * configure.in: Changes for stackovf.h: Check for sigcontext,
5688 sigaction, sigstack, and define rlim_t as int if necessary.
5689 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
5690 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
5691 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
5693 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
5695 * configure.in: Use AC_SET_MAKE.
5696 * Makefile.in: Use @SET_MAKE@.
5697 Reported by Jim Meyering.
5699 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
5700 Reported by Ian Taylor.
5702 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
5704 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
5705 because siginfo.h is unrelated to standard headers, and siginfo.h
5706 is already checked for.
5707 Reported by Joseph E. Sacco.
5709 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
5711 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
5714 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
5716 * builtin.c (substitute): Use \& to represent this part of the
5717 string which was matched by the whole regexp, instead of
5718 representing the whole string. Any usage of \0 issues a warning
5719 and acts like \&, it will disappear in some subsequent release.
5721 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
5723 * m4.c: Complete prototype for forwarded declaration of usage.
5725 * input.c (init_macro_token): Correct own reference in error
5726 message. Previous name get_macro_func was referred to instead.
5727 (next_char): Correct own reference in error message. Previous
5728 name advance_input was referred to instead.
5730 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
5731 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
5732 and_term, not_term, logical_not_term, cmp_term, shift_term,
5733 add_term, mult_term, exp_term, unary_term, simple_term): Add
5734 prototype to forwarded declarations. Declare parameter v1 as
5735 eval_t * instead of int *. Same for local variable v2 in dyadic
5736 functions. Same for result in exp_term.
5737 * builtin.c (m4_eval): Declare value as eval_t instead of int.
5738 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
5739 unsigned_eval_t instead of unsigned int. Change casts accordingly.
5740 (shipout_int): Cast first argument of ntoa to eval_t.
5741 Reported by Thorsten Ohl.
5743 * macro.c: Complete the prototypes of forwarded expand_macro and
5745 Reported by Thorsten Ohl.
5747 * m4.h: Define voidstar as void * or char * depending on __STDC__.
5748 The Ultrix 3.1 compiler cannot do much with void pointers.
5750 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
5751 * m4.c (xfree): Replace void * by voidstar.
5752 Reported by Tom McConnell.
5754 * ansi2knr.1: New, from elsewhere.
5755 * Makefile.in (DISTFILES): Distribute ansi2knr.1
5757 * Makefile.in (stamp-h.in): Avoid running ./config.status if
5758 stamp-h does not exist yet. This avoids running it a second time
5759 just after the initial ./configure.
5760 Reported by David MacKenzie and Tom McConnell.
5762 * m4.h: Replace the enum debug_info declaration with a series of
5763 #define's. The Ultrix 3.1 compiler would otherwise need casting
5764 (int) to most references, when used in expressions.
5765 Reported by Tom McConnell.
5767 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
5769 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
5770 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
5771 calls the compiler. Previously, FP_PROTOTYPES was only calling
5772 the preprocessor; by not being subject to CFLAGS, this was
5773 discouraging those flags asking for ANSI compilation.
5774 * acconfig.h: Document HAVE_PROTOTYPES.
5775 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
5776 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
5777 Reported by Eric Backus.
5779 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
5780 from the environment. Default CFLAGS to -g if not set.
5781 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
5782 * lib/Makefile.in: Have CFLAGS substituted from configure.
5783 Reported by Eric Backus and Tom McConnell.
5785 * configure.in: m4_undefine changeword before using AC_ENABLE.
5787 * m4.h: Declare prototypes for error (for ANSI compilers only),
5788 prefix_all_builtins and reference_error.
5789 Reported by Tom McConnell.
5791 * input.c (set_word_regexp): Do not try to initialize the array

5881 also tested it on a Sun Sparc workstation running SunOS 4.x.
5883 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
5884 49.format check, abusing a `union values' argument with sprintf
5885 without selecting the proper field. Now, save the formatting type
5886 first, delaying the fetch of the corresponding argument.
5887 Reported by Joseph E. Sacco and Tom Quinn.
5889 * format.c (format): Remove const from char *fmt declaration when
5890 not HAVE_EFGCVT, because a NUL may be forced into it.

5936 warning from gcc about `repl' possibly used before defined.
5937 Reported by Jim Meyering.
5939 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
5940 Reported by Jim Meyering.
5942 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
5944 * m4.h: Move the conditional definition of volatile after the
5945 inclusion of system files, because they may define it first.
5947 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
5949 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
5950 get around a problem with Alpha make seeing a syntax error, there.

5973 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
5974 syserr() macro. Delete errref, add reference_error and M4ERROR.
5975 * m4.c: Replace errref, which was returning an input reference
5976 string, with reference_error, which prints it on standard error.
5977 * builtin.c, output.c: Use errno as second parameter to error,
5978 instead of using syserr() with %s.
5979 * *.c: Use M4ERROR instead of error: no more errref() with %s.
5980 Doing so, the program name appears after the input reference
5981 instead of before, which eases M-x next-error processing.
5983 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
5985 * checks/get-them: Escape braces with backslashes in patterns,

6027 expected is on the left and the obtained on the right.
6029 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR

6031 internal_error, add declaration for error_message_prefix.
6032 * m4.c: Delete m4error, warning, fatal and internal_error
6033 routines, add error_message_prefix routine.
6034 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
6035 warning with WARNING*, fatal with FATAL* and internal_error with
6037 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
6038 this is not needed anymore.
6040 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
6041 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
6042 and debug_message, add declaration for debug_message_prefix.

6318 * Makefile.in (texclean, mostlyclean): New goals.
6320 * Makefile.in (clean): Remove clutter from ansi2knr.
6321 Reported by Pierre Gaumond.
6323 1992-12-20 François Pinard <pinard@iro.umontreal.ca>
6325 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
6326 might well use CFLAGS is s/he needs it.
6328 * Makefile.in: Allow installation of info files from a separate
6330 Reported by Jason Merrill.
6331 Reported by David MacKenzie.
6332 Reported by Skip Montanaro.
6333 Reported by Erez Zadok.
6334 Reported by Assar Westerlund.
6336 1992-12-19 François Pinard <pinard@iro.umontreal.ca>
6339 This is still a beta release for the future GNU m4 version 1.1.
6341 * lib/alloca.c: New, from elsewhere.
6342 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
6344 * m4.h: Do not define index/rindex if already defined. If
6345 FALSE/TRUE are already defined, do not redefine them, but merely
6346 define boolean typedef to int.
6348 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
6349 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
6350 because some C compilers do not like connectives with #ifdef.
6351 * m4.h: Define `volatile' only if __GNUC__, instead of once for
6352 __GNUC__ and once for __STDC__.
6353 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
6355 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
6356 Makefile dependencies. Without it, make keeps destroying and
6357 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
6359 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
6360 to diversion/DIVERSION, this was a spelling error.
6362 * m4.c: Declare version[], remove #include "version.h".
6363 * version.h: Deleted.
6364 * Makefile.in: Remove references to version.h.
6366 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
6367 production, by using a simpler and more robust algorithm. This
6368 solves the problem of synclines sometimes written in the middle of
6369 an output line. Delete sync_line() and output_lines variable.
6370 * m4.h: Remove sync_line prototype and output_lines declaration.
6371 * input.c (next_char), output.c (shipout_text): Remove references
6373 * input.c (push_file, pop_file): Merely put the value -1 in
6374 output_current_line instead of calling sync_line, for delaying a
6375 single `#line NUM FILE' before next output line. Do not test
6376 for sync_output, because this is unnecessary clutter.
6377 * output.c (make_divertion, insert_divertion): Idem.
6378 * input.c: Rename must_advance_line to start_of_input_line, for
6381 * debug.c (trace_header): Select a new debug line format, which
6382 better complies with GNU standards for formatting error messages.
6383 With option `-dfl', M-x next-error might be used on the output.
6384 * m4.c (vmesg): Adjust format of error output to GNU standards.
6385 * m4.texinfo: Adjust examples for `make check' to work.
6387 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
6388 case for enum debug_info constants, which were all lower case.
6390 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
6392 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
6393 collected patches. I tried a few times using newer regex.[ch], it
6394 mysteriously stopped aborting with this one. Insecure feeling...
6395 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
6397 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
6399 * m4.c: Change `--no-warnings' to `--silent'.
6400 Reported by David MacKenzie.
6402 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
6403 leave it off for now. See comment in m4.c for justification.
6404 Reported by David MacKenzie.
6406 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
6407 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
6409 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
6411 * Makefile.in: Ensure recursive cleaning is done before local
6412 cleaning for all clean goals.
6414 * builtin.c (ntoa): Ensure the value is always interpreted as a
6415 signed quantity, whatever the radix is.
6417 1992-11-18 Jim Meyering <meyering@idefix>
6419 * builtin.c, format.c, input.c: Split long lines.
6420 * m4.c: Use typedef macro_definition instead of struct
6422 * symtab.c: Use typedef symbol instead of struct symbol.
6424 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
6426 * *.[ch]: Remove all trailing whitespace, in code and comments.
6428 * configure.in: Find some awk.
6429 * Makefile.in: Add $(AWK) to MDEFINES.
6430 * checks/Makefile.in: Transmit $(AWK) to get_them.
6431 * checks/get_them: Use $AWK instead of gawk. Add a close in the
6432 awk script when switching files, because without this, mawk runs
6433 out of file descriptors.
6435 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
6437 * Makefile.in (realclean): Delete m4.info*.
6438 Reported by Jim Meyering.
6440 * Makefile.in: Adjust and link with checks/Makefile.
6441 * checks/Makefile.in: New.
6442 * configure.in: Output checks/Makefile.
6444 * checks/get_them: Have the dnl header of each test more
6445 recognizable by next-error, also use a better message.
6447 1992-11-16 Jim Meyering <meyering@idefix>
6449 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
6450 And use that only if __GNUC__ since we're using it's GCC-specific
6451 semantics that tell the compiler the associated function doesn't
6454 * builtin.c (substitute): Don't use character as an array index.
6455 (dumpdef_cmp): Make formal arguments `const void *' to avoid
6456 warnings with gcc -W -Wall on systems with qsort prototype.
6457 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
6460 * eval.c (most functions): Add parentheses to assignments used
6461 as truth values go avoid warnings from gcc -Wall.
6463 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
6464 any functions that don't need external scope.
6466 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
6467 (many functions and arrays): Declare `const'.
6469 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
6471 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
6472 removing the declaration from m4.h. Also rename false to FALSE
6475 * lib/Makefile.in (Makefile): New goal.
6477 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
6478 so heavily loaded. It gets more easily overridable, calling make.
6479 Reported by Jim Meyering.
6481 * Makefile.in (dist): Get .fname from the current directory name,
6482 instead of from version.h. I need updating many files manually,
6483 when the version changes, version.h is just one of them.
6485 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
6487 * m4.h: Remove the tag `boolean' on the enum introducing typedef
6488 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
6489 Reported by Tom McConnell.
6491 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
6493 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
6494 39.cleardiv, which were describing missing or spurious newlines.
6495 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
6496 do not depend on machine word size, `/bin/false' implementation,
6497 or `wc' output format. `make check' is more dependable, now.
6499 * checks/check_them: Summarize the failed tests by listing their
6500 name, at end. If none, issue `All checks successful'. Output
6501 `Checking' instead of `Input file:'.
6503 * checks/get_them, checks/check_them: Reindented.
6505 * Makefile.in (dist): chmod a+r before making the tar file.
6507 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
6509 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
6511 * input.c (next_token): Reinitialize token_buttom just after using
6512 it as a watermark with obstack_free. Or else, a future token, big
6513 enough for triggering reallocation of the obstack chunk, could
6514 void the initialized value of token_buttom, later causing panic in
6515 obstack_free. Rename token_buttom to token_bottom everywhere.
6517 * m4.h: Before declaring errno, first include <errno.h> and
6518 ensure that it does not define errno.
6519 Reported by Richard Stallman.
6521 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
6523 * builtin.c: Define and use DECLARE macro for builtins.
6525 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
6526 argument, this is a common idiom for introducing long comments.
6528 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
6529 arguments. The last argument was silently ignored.
6531 * m4.c (cmd_error): Add a missing semicolon before va_end().
6533 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
6535 * Makefile.in: Now handle protoized sources. Define and use U.
6536 Compile and use ansi2knr with old compilers. Update DISTFILES.
6537 Add `aclocal.m4' to `configure' dependencies.
6538 * ansi2knr.c: New, from Ghostscript distribution.
6539 * configure.in: Define U through FP_PROTOTYPES for old compilers.
6540 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
6541 * aclocal.m4: New, provide FP_PROTOTYPES.
6542 * m4.h: Conditionnaly protoized through Args, save for varags.
6543 * builtin.c: Protoized. Then:
6544 Include <sys/types.h> if size_t is not defined, before "regex.h".
6545 (m4_ifelse): Fetch built-in name properly for diagnostic.
6546 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
6547 (m4_regexp): Add const to `msg' declaration.
6548 (m4_patsubst): Add const to `msg' declaration.
6549 * debug.c: Protoized, save for varargs.
6550 * eval.c: Protoized.
6551 * format.c: Protoized.
6552 * input.c: Protoized.
6553 * m4.c: Protoized, save for varargs. Then:
6554 (xfree): Accept void * instead of char *.
6555 (xmalloc): Return void * instead of char *.
6556 (xrealloc): Accept and return void * instead of char *.
6557 * macro.c: Protoized.
6558 * output.c: Protoized.
6559 * path.c: Protoized. Then cast some (char *) over xmalloc's.
6560 * symtab.c: Protoized.
6562 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
6564 * m4.texinfo: Remove directory from diagnostics in 30.include,
6565 51.eval, 56.errprint and 57.m4exit tests.
6567 * m4.h: Remove declarations for int or void system functions, they
6568 cause more conflicting trouble than they make good.
6570 * configure.in: Avoid configuration header file. Add some tests.
6571 * m4.h: Remove #include "config.h".
6572 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
6573 Then, rewritten for better compliance with GNU standards.
6575 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
6577 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
6578 because of a misplaced #endif.
6580 * Many *.[hc] files: Correct intra-line spacing here and there,
6581 according to GNU indent 1.6 advice.
6583 * configure.in: New, using Autoconf 1.2.
6584 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
6585 * Delete old configure.in, configure, etc/configure.in,
6586 etc/configure, lib/configure.in, lib/configure and config/*.
6587 Reported by Jason Merrill.
6589 * symtab.c (hash): Change (char) NULL to '\0'.
6590 Reported by Jason Merrill.
6592 * Delete .vers, etc/newdist.sh, etc/newvers.sh and
6593 etc/nextvers.sh. Release numbers will be edited `by hand'.
6594 * version.h: De-automatize, force value in.
6596 * m4.c: Changes in order to use a newer getopt.h.
6597 Reported by David MacKenzie.
6599 * checks/: New name for examples/.
6600 * checks/get_them: New location for etc/get_examples.
6601 * checks/check_them: New location for etc/check_examples.
6602 * Makefile.in, checks/get_them, checks/check_them: Adjust.
6603 * lib/vfprintf.c: New location for etc/vfprintf.c.
6604 * Delete empty etc/.
6605 * examples/: New name for test/.
6607 1992-03-10 François Pinard <pinard@iro.umontreal.ca>
6609 * Makefile.in (check): Add m4 as dependency.
6611 * m4.c: Accept --no-warnings instead of --no_warnings, and
6612 --no-gnu-extensions instead of --no_gnu_extensions. Make the
6613 usage message more informative.
6614 Reported by David MacKenzie.
6616 1992-03-09 François Pinard <pinard@iro.umontreal.ca>
6618 * etc/check_examples: New name for check_examples.sh.

6620 * Makefile.in, etc/Makefile.in: Use new names.
6622 * Makefile.in: Transmit $(CC) while making in lib.
6624 * Many *.[hc] files: GNU indent'ed, with further fine tuning of
6625 code disposition by hand.
6627 1992-03-08 François Pinard <pinard@iro.umontreal.ca>
6629 * m4.h: Delete definitions for abort() and exit().
6630 Reported by Richard Stallman.
6632 * config/hmake-unicos, config/s-unicos.h: New files.
6633 Reported by Hal Peterson.
6635 * eval.c (exp_term): Have N^0 return 1.
6636 Reported by Michael Fetterman.
6638 * eval.c, input.c, m4.h: Remove last comma in enums.
6639 Reported by Mike Lijewski.
6641 * Transfer of maintenance duties from René to François.
6643 1991-10-24 René Seindal <seindal@diku.dk>

6653 missing or superflous arguments to built-in macros.
6655 * Added default options via the M4OPTS environment variable.
6657 * The built-in format can now be configured to use sprintf as
6658 the formatting engine, for systems without [efg]cvt(3).
6660 * GNU library code is moved to the ./lib subdirectory; other
6661 utility files are now in ./etc.
6663 * Several minor bugs have been fixed.
6665 1991-07-26 René Seindal <seindal@diku.dk>
6667 * Fixed various bugs. Release 0.99, manual 0.09. Many thanks to
6668 Francois Pinard and Roland H. Pesch for providing me with reports.
6670 * The builtins incr and decr are now implemented without use of
6673 * The builtin indir is added, to allow for indirect macro calls
6674 (allows use of "illegal" macro names).
6676 * The debugging and tracing facilities has been enhanced
6677 considerably. See the manual for details.
6679 * The -tMACRO option is added, marks MACRO for tracing as soon
6682 * Builtins are traced after renaming iff they were before.
6684 * Named files can now be undiverted.
6686 * The -Nnum option can be used to increase the number of
6687 divertions available.
6689 * Calling changecom without arguments now disables all comment
6692 * The function m4_patsubst() is now consistently declared
6695 * A bug in dnl is fixed.
6697 * A bug in the multi-character quoting code is fixed.
6699 * Several typos in the manual has been corrected. More probably
6702 * The m4.info file is now installed along with the program.
