2424 * ltdl/m4/gnulib-cache.m4: ...this new file, per new gnulib-tool
2426 * bootstrap: Update usage of gnulib-tool.
2428 2006-05-04 Eric Blake <ebb9@byu.net>
2430 * Makefile.am (doc/m4.1): Use EXEEXT on built binary.
2433 2005-12-05 Gary V. Vaughan <gary@gnu.org>
2435 * bootstrap (func_update_po): Synch with CVS GNU tar. wget 1.9.x
2436 and 1.10.x support --cache=off, so $WGETFLAGS are not necessary.
2437 Reported by Eric Blake <ebb9@byu.net>
2439 2005-12-04 Gary V. Vaughan <gary@gnu.org>
2441 * bootstrap (func_update_po): Test and set $WGETFLAGS to disable
2442 http caching as -C is no longer supported by wget 1.10.x.
2443 Reported by Eric Blake <ebb9@byu.net>
2445 2005-10-20 Gary V. Vaughan <gary@gnu.org>
2447 * m4/module.c (caller_id): To match libtool-2.0 interface, changed
2449 (iface_id): ...an lt_dlinterface_id type.
2450 (m4__module_find): New abstraction for lt_dlhandle_fetch. Use
2451 throughout, instead of calling obsolete lt_dlhandle_find directly.
2452 (m4__module_next): Use multiloader-safe lt_dlhandle_iterate. Use
2453 throughout, instead of calling obsolete lt_dlhandle_next.
2454 * m4/m4private.h (m4__module_find): Declare it.
2455 * m4/builtin.c (m4_builtin_find_by_name, m4_builtin_find_by_func):
2456 Use m4__module_next instead of obsolete lt_dlhandle_next.
2458 2005-10-20 Gary V. Vaughan <gary@gnu.org>
2460 * bootstrap (func_update_po): Update pofiles directly from the
2461 translation project.
2462 * po/LINGUAS, po/cs.po, po/de.po, po/el.po, po/fr.po, po/it.po,
2463 po/ja.po, po/nl.po, po/pl.po, po/ru.po, po/sv.po: No need to store
2464 these files under source control anymore.
2465 Suggested by Eric Blake <ebb9@byu.net>
2467 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2469 * ltdl/m4/m4-gnulib.m4: Update FSF contact address. Somehow this
2470 file escaped the address updates on 2005-05-01.
2472 2005-07-07 Gary V. Vaughan <gary@gnu.org>
2474 * bootstrap: Allow user overriding of gnulib-tool location, and
2475 correctly determine module source directories whether gnulib-tool
2476 is given as a relative or absolute path, or is found by searching
2478 Reported by Eric Blake <ebb9@byu.net>
2480 2005-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2482 * ltdl/m4/debug.m4 (m4_CHECK_DEBUGGING): Make sure that both $rm
2483 and $RM are defined for various versions of
2484 AC_LIBTOOL_COMPILER_OPTION.
2486 * bootstrap (AUTORECONF): New variable to allow user overriding of
2489 2005-07-07 Gary V. Vaughan <gary@gnu.org>
2491 * doc/m4.texinfo (History): Add better notes on the ancestory of
2492 GNU m4, and other historical interest.
2494 2005-05-08 Gary V. Vaughan <gary@gnu.org>
2496 * m4/symtab.c (m4_symbol_rename): New function that performs a low
2497 level symbol rename.
2498 * m4/m4module.h (m4_symbol_rename): Declare it as part of the API.
2499 * modules/gnu.c (regsub): Factored out of m4_epatsubst_do...
2500 (m4_patsubst_do, m4_renamesyms_do): ...wrappers that use
2502 (erenamesyms, renamesyms): ...builtins that use these to implement
2503 macro renaming by regular expression.
2504 * doc/m4.texinfo (Erenamesyms and Renamesyms): Document them.
2505 * tests/generate.awk: Allow some forbidden `m4_' prefixed symbols
2506 to stop the new generated tests from choking.
2508 2005-05-07 Gary V. Vaughan <gary@gnu.org>
2510 Since most of the build is handled from a single Makefile.am now,
2511 we can teach make about the dependencies between the m4 binary and
2512 the preopened modules it is built against:
2514 * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
2516 * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
2517 of the preopened modules have changed.
2519 2005-05-07 Gary V. Vaughan <gary@gnu.org>
2521 * configure.ac (gl_MODULES): Add mkstemp for machines that don't
2522 have a native implementation.
2524 2005-05-06 Gary V. Vaughan <gary@gnu.org>
2526 * src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are
2527 handled already by gnu/exit.h.
2529 * configure.ac (gl_MODULES): Add assert to support a
2530 --disable-assert configure time option for NDEBUG setting.
2532 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.
2533 * bootstrap (src_modules): Add version-etc-fsf.
2534 * src/main.c (version_etc_copyright): Removed.
2536 * ltdl/m4/m4-getopt.m4 (m4_GETOPT): Synch with gnulib/getopt.m4.
2538 2005-05-04 Gary V. Vaughan <gary@gnu.org>
2540 * src/m4.h (__CYGWIN__, WIN32): Canonicalise Windows and Cygwin
2542 * src/freeze.c (produce_frozen_state): Use \n line-endings even
2543 on Windows, so that the frozen file reader will work.
2544 Reported by Josef T. Burger <bolo@bolo.com>
2546 2005-05-04 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
2548 Forward port of a patch that allowed m4-1.4.2 to compile on
2551 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
2553 * src/m4.h: And include them as appropriate.
2554 * src/main.c, src/stackovf.h: Don't include signal.h literally;
2555 m4.h will include the correct file.
2557 2005-05-04 Gary V. Vaughan <gary@gnu.org>
2559 * m4/m4private.h: Make errno visible for the sources patched
2562 2005-05-04 Paul Eggert <eggert@twinsun.com>
2564 * src/main.c (print_program_name_CB): Preserve errno, since
2565 M4ERROR relies on this.
2566 * modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
2567 * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
2568 * m4/path.c (m4_path_search): Don't let "free" trash errno when
2571 * m4/output.c (m4_insert_file): Don't assume errno has a valid
2572 value simply because fread returns zero. This fixes a
2573 portability bug reported by Marion Hakanson in
2574 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
2576 2005-05-04 Santiago Vila <sanvila@debian.org>
2578 * tests/stackovf.test: Use tempfile if available.
2580 2005-05-04 Robert Bihlmeyer <robbe@orcus.priv.at> (tiny change)
2582 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=92629
2583 * m4/output.c (m4_insert_file): Do not mix buffered and
2584 unbuffered I/O, as this breaks on the Hurd.
2586 2005-05-04 Gary V. Vaughan <gary@gnu.org>
2588 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
2589 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
2590 and libtoolize does a better job of ltdl importing now too, so
2591 take advantage of that while updating the tree:
2593 * acm4, config: Moved from here...
2594 * ltdl/m4, ltdl/config: ...to here.
2595 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
2596 src/Makefile.am, tests/Makefile.am: Removed...
2597 * Makefile.am: ...and migrated to here, with adjustments to
2598 compensate for relative path differences.
2599 * commit: Adjust relative paths.
2600 * configure.ac: Adjust relative paths.
2601 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
2603 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
2604 the meanwhile, CVS HEAD libtool is needed.
2605 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
2606 stricly new enough, we also need a patch.
2607 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
2608 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
2609 (gl_MODULES): Don't list getopt and version-etc, as they don't
2611 * bootstrap: After running gnulib-tool to import the listed
2612 modules, fetch getopt and version-etc into src manually.
2613 (ltdldir): Change to ltdl.
2614 * src/main.c: Adjust for changes in version-etc API.
2615 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
2616 but works when the getopt module isn't to be included in the lib.
2617 * README: Add note about patching autoconf and automake to
2620 2005-05-02 Matt Kraai <kraai@debian.org> (tiny change)
2622 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=84416
2623 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
2624 empty file rather than to a nonexistent file. This closes a
2625 common security hole.
2626 * modules/m4.c (m4_maketemp): Implement the above, by using
2627 mkstemp rather than mktemp.
2629 2005-05-01 Gary V. Vaughan <gary@gnu.org>
2631 The FSF are moving offices today. Changed their contact address
2632 in all files from `59 Temple Place, Suite 330, MA 02111-1307' to
2633 `51 Franklin Street, Fifth Floor, MA 02110-1301'.
2635 2005-03-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
2637 * tests/Makefile (clean-local): Ignore testsuite cleanup
2640 2005-03-11 Per Bothner <per@bothner.com> (tiny change)
2642 * tests/Makefile (clean-local): Only run the testsuite cleanup
2643 if the testsuite has been generated.
2645 2005-02-11 Stepan Kasal <kasal@ucw.cz>
2647 * TODO: slight clarification of the example of qindir usage.
2649 2005-02-08 Gary V. Vaughan <gary@gnu.org>

2652 From Stepan Kasal <kasal@ucw.cz>
2654 2005-02-08 Stepan Kasal <kasal@ucw.cz>
2656 * TODO: Add ``execution stack'', fix a typo.
2657 * doc/m4.texinfo: Typos.
2659 2004-12-24 Eric Blake <ebb9@byu.net>
2661 * configure.ac (INCLUDE_STDBOOL_H): Account for gnulib's move
2662 to the gnu subdirectory.
2663 * acm4/m4-error.m4 (INCLUDE_ERROR_H): Likewise.
2664 * acm4/m4-obstack.m4 (INCLUDE_OBSTACK_H): Likewise.
2665 * acm4/m4-regex.m4 (INCLUDE_REGEX_H): Likewise.
2666 * m4/system_.h: Likewise, in non-configured includes.
2668 2004-10-14 Noah Misch <noah@cs.caltech.edu>,
2669 Gary V. Vaughan <gary@gnu.org>
2671 * m4/m4.c (m4_context_field_table, m4_context_opt_bit_table):
2672 Protect definitions from macro expansion under -DNDEBUG by
2673 parenthesising the expanded function names.
2674 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
2675 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
2676 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
2677 (m4_is_syntax_macro_escaped): Similarly protect function
2678 definitions from macro expansion under -DNDEBUG by #undefing the
2679 matching macro names before each definition. Also, move all the
2680 function definitions to the end of the file so that any
2681 invocations in the rest of the file pick up the fast macro
2683 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)
2684 (m4_set_debug_file, m4_set_trace_messages)
2685 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
2686 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
2687 (m4_set_max_debug_arg_length_opt): New fast macro versions of the
2688 option setter functions.
2690 2004-09-23 Gary V. Vaughan <gary@gnu.org>
2692 * po/POTFILES.in: Reflect move of gnulib files from gnulib/m4
2695 2004-09-23 Gary V. Vaughan <gary@gnu.org>
2697 * src/main.c: Include gnulib files from the correct directory.
2699 * gnulib/*: Don't store any of the gnulib files in arch, as they
2700 generate spurious changes.
2701 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
2702 gnulib macros now share our macro directory.
2703 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
2704 * bootstrap: Call gnulib-tool to import from the gnulib tree.
2705 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
2706 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
2707 the gettext macros from autopoint that overwrite the gnulib-tool
2708 imported versions. Import sources and Makefile.am into the `gnu'
2709 directory. Changed all callers.
2710 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
2711 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
2712 for imported modules.
2713 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
2714 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
2715 hardcoding the gnulib macros they wrap.
2717 2004-07-15 Gary V. Vaughan <gary@gnu.org>
2719 Latest CVS libtool can preload modules in libraries, including
2720 its own module loaders! Tweak m4 so that it doesn't try to treat
2721 libltdl's module loaders as m4 modules when freezing and on exit:
2723 * gnulib/acm4/*.m4: Don't store these files in arch since they
2724 generate spurious changes.
2725 * bootstrap: Simplify initial libtoolize call, since CVS
2726 libtoolize is smarter these days.
2727 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
2729 * m4/module.h (m4__module_exit): Missing declaration.
2730 * m4/m4private.h (m4__module_next): New function declaration.
2731 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
2732 encapsulation. Changed all callers.
2733 (m4__module_interface): New function to verify m4 loadable module
2735 (m4__module_init): Register the interface validator.
2736 (m4__module_exit): Only close my own modules.
2737 * modules/m4.c (unistd.h): Provide missing declaration.
2738 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
2739 (m4_expand_ranges): More missing declarations.
2740 * modules/modtest.c (export_test): Ditto.
2741 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
2742 * src/main.c (main): Bump copyright year.
2743 * tests/modules.at: Fix sed syntax error.
2746 2004-06-17 Gary V. Vaughan <gary@gnu.org>
2748 Tweaking to enable compilation with latest CVS libtool and
2749 libltdl. We can't just dump the library files directly into the
2750 m4 directory anymore now that libltdl is built from pieces itself:
2752 * bootstrap: Rewritten to use latest libtoolize sanely, and to
2753 set up libltdl subdirectory.
2754 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
2755 gnulib subdirectory's config.
2756 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
2757 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
2759 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
2760 configure.ac, so use AC_WITH_LTDL instead.
2761 * Makefile.am (SUBDIRS): Add libltdl.
2762 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
2764 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
2765 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
2766 (libm4_la_LIBADD): Add LIBLTDL.
2767 * m4/ltdl.c, m4/ltdl.h: Removed.
2768 * m4/m4module.h: Include canonical ltdl.h.
2771 2004-06-14 Gary V. Vaughan <gary@gnu.org>
2773 * gnulib/import: Now updates makefile fragments, and configure.ac.
2774 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
2775 * gnulib/m4/Makefile.am: include it.
2776 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
2777 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
2778 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
2779 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
2780 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
2781 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,
2782 gnulib/acm4/lib-ld.m4, gnulib/acm4/lib-prefix.m4,
2783 gnulib/acm4/error.m4, gnulib/acm4/po.m4, gnulib/acm4/regex.m4,
2784 gnulib/acm4/stdbool.m4, gnulib/acm4/stdint_h.m4,
2785 gnulib/acm4/uintmax_t.m4, gnulib/acm4/ulonglong.m4,
2786 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
2787 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
2788 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
2790 * gnulib/m4/getopt_int.h: New source file from latest gnulib
2792 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
2793 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,
2794 gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
2795 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
2796 Updated source files from latest gnulib.
2798 2004-02-29 Gary V. Vaughan <gary@gnu.org>
2800 * config/mailnotify: New file for mailing commit notifications,
2801 imported from cvs-utils.
2802 * commit: Updated from cvs-utils and tweaked for m4.
2804 2003-12-01 Gary V. Vaughan <gary@gnu.org>
2806 * config/mkstamp: Updated from CVS libtool.
2807 * configure.ac: Generate a gnu coding standards compliant version
2808 number, and use it for the banner.
2809 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
2810 mhen the TIMESTAMP changes in ChangeLog, but the file modification
2811 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
2812 contain the previous version number.
2813 * src/main.c: Make --version output conform to the GNU standard.
2815 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
2816 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
2817 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
2818 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
2819 time_la_SOURCES): ...so that these are defaulted correctly, and
2820 can be removed from this file.
2821 (AM_LDFLAGS): Add -module...
2822 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
2823 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
2824 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
2825 the individual settings can be removed.
2826 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
2827 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
2828 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
2829 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
2830 time_la_LIBADD): ...so that these are picked up as a deplib of
2831 libm4 and don't need to be set explicitly.
2833 2003-11-18 Gary V. Vaughan <gary@gnu.org>
2835 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
2836 from the standard build. It is too fragile.
2838 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
2839 CVS libtool after merging m4 changes across to libtool.
2841 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
2842 * m4/path.c (search_path_add): Ditto.
2844 2003-11-13 Gary V. Vaughan <gary@gnu.org>
2846 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
2847 libtool tags we don't use in configure. This reduces the size
2848 of the script from over 1Mb to under 700Kb.
2850 2003-11-13 Gary V. Vaughan <gary@gnu.org>
2852 The import script was not written properly, and the last gnulib
2853 import was incomplete. Fixed that problem, and reimport our
2854 gnulib dependencies, which picks up the address calculation
2855 overflow checks described by Paul below. Also tweak the clients
2856 of the gnulib xalloc module not to use deprecated macros:
2858 * gnulib/import: Recurse through module dependencies rather than
2859 naively descending only one level.
2860 * configure.ac: Add calls to gnulib's strnlen and extension module
2862 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
2864 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,

2869 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
2870 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in

2885 2003-10-10 Gary V. Vaughan <gary@gnu.org>

2888 thinking, and use AT_CHECK to compare the output of a sed pass
2889 over stderr against the canonical strerror string.
2891 * tests/modules.at (modules: importing): Edit the generated stderr
2892 output to canonicalize strerror output, before a comparison.
2894 2003-10-10 Gary V. Vaughan <gary@gnu.org>
2896 Tru64UNIX perl is sloppy with namespace pollution. This patch is
2897 careful not to trip over the mess:
2899 * modules/perl.c: Some builds of perl install headers that contain
2900 `#define try __builtin_try'. Be sure to undefine that macro
2901 before `m4/hash.h' gets included, which uses the `try' symbol.
2902 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
2903 `false' before including `stdbool.h'.
2904 (DELETE): This symbol is not in m4's namespace, and is in any
2905 case only used internally...
2906 * m4/m4private.h (DELETE): ...so move it to here.

2911 Don't use XMALLOC and XCALLOC. Once we install the
2912 corresponding patch into gnulib, this will fix some
2913 address-calculation overflow bugs on hosts where calloc (A, B)
2914 returns garbage when A*B overflows.
2916 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
2917 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
2918 xmalloc, XCALLOC with xcalloc.

2931 * gnulib/Makefile.am (EXTRA_DIST): Removed.
2932 (MAINTAINERCLEANFILES): Add Makefile.in.
2933 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
2935 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.

2984 gnulib with gnulib/import script.
2985 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
2986 guards ready for gnulib-tool to autoupdate on import.
2987 * config/debug.m4, config/gmp.m4, config/m4-error.m4,
2988 config/m4-gettext.m4, config/m4-obstack.m4, config/m4-regex.m4,

2991 acm4/m4-gettext.m4, acm4/m4-obstack.m4, acm4/m4-regex.m4,
2992 acm4/stackovf.m4: ...to here, to separate aclocal macros from
2993 configure time helper scripts.

2995 * m4/hash.c, m4/m4.c, m4/macro.c, m4/module.c, m4/output.c,
2996 m4/path.c, m4/symtab.c, m4/syntax, m4/system_.h, modules/m4.c,
2997 src/main.c, src/stackovf.c: s/xfree/free/g to comply with new
2999 * src/main.c (version_etc_copyright): Only output the current
3001 (version_etc): Call with new variadic API.
3003 2003-09-16 Gary V. Vaughan <gary@gnu.org>
3005 * gnulib/m4/version-etc.c, gnulib/m4/version-etc.h: Import
3006 version-etc module from CVS gnulib.
3007 * po/POTFILES.in: Add gnulib/m4/version-etc.c.
3008 * src/Makefile.am: Build it.
3009 * src/main.c: Use it.
3011 * gnulib/m4/exit.h: Import exit module from CVS gnulib.
3012 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
3013 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
3016 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
3017 Gary V. Vaughan <gary@gnu.org>
3019 * bootstrap: Separate options.
3020 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
3021 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
3023 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
3024 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
3025 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
3026 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
3027 $(LTLIBINTL) for gettext support on cygwin.
3028 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
3029 have $(LTLIBINTL) from the preloaded module la files.
3030 * README: Remove the warning about using --disable-nls on Windows
3033 2003-09-15 Gary V. Vaughan <gary@gnu.org>
3035 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
3036 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
3039 2003-09-12 Gary V. Vaughan <gary@gnu.org>
3041 * doc/STYLE: Document the gnulib header naming conventions, and
3043 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
3044 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,
3045 gnulib/m4/gettext.h, gnulib/m4/obstack.h, gnulib/m4/regex.h
3047 * gnulib/m4/Makefile.am: Remove the rules to build these headers.
3049 * gnulib/m4/strtol.c, gnulib/config/strtol.m4: Import strtol
3050 module from CVS gnulib.
3051 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
3052 (gl_FUNC_STRTOL): In favour of the module macro.
3054 2003-09-12 Gary V. Vaughan <gary@gnu.org>
3056 Replace the getopt code with CVS gnulib getopt. The source files
3057 detect whether they are in a glibc environment and preprocess away
3058 all of the code if there is a system getopt, so we can compile
3059 them into the m4 executable unconditionally:
3061 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
3062 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
3063 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
3065 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
3067 * src/Makefile.am: Adjust.
3068 * src/main.c: Always include our shipped getopt.h.
3069 * po/POTFILES.in: Use new location of getopt.c.
3071 2003-09-12 Gary V. Vaughan <gary@gnu.org>
3073 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
3074 * config/Makefile.am: Removed. Automake 1.8 distributes the files
3075 in this directory automatically.
3076 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
3078 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
3080 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
3082 * modules/Makefile.am (pkglibexecdir): Set it here.
3083 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
3085 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
3086 Import regex module from CVS gnulib.
3087 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
3088 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
3089 do extra substitutions for Makefile.
3090 * configure.ac: Use it.
3091 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
3092 from regex_.h if necessary.
3093 * m4/system_.h: Include the correct version of regex.h.
3094 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
3096 * po/POTFILES.in: Use new location of regex.c.
3098 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
3099 realloc.c: automake distributes these files already.
3101 2003-09-12 Gary V. Vaughan <gary@gnu.org>
3103 Replace the xstrzdup code by importing the xstrndup module from
3104 CVS gnulib, along with its dependencies: strndup and strnlen:
3106 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
3107 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
3109 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
3110 gnulib/config/strndup.m4: Ditto wrt strndup.
3111 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
3113 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
3114 However, contrary to gnulib, we install xstrndup.h.
3115 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
3116 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
3117 is an artifact of the old m4 portability layer.
3118 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
3119 * m4/system_.h: Include xstrndup.h.
3120 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
3122 2003-09-11 Gary V. Vaughan <gary@gnu.org>
3124 Reimport the latest xalloc module from CVS gnulib, and adjust the
3125 m4 sources to take advantage of xalloc xfree. Also create a new
3126 macro DELETE with the same semantics as the old m4 XFREE macro,
3127 and carefully tweak callers:
3129 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
3131 * m4/utility.c (xfree): Removed. This function is now supplied by
3133 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
3134 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
3135 * m4/symtab.c (m4_symtab_create): Ditto.
3136 * m4/system_.h: Removed XFREE redefine.
3137 (DELETE): New macro with same functionality as the original m4
3138 XFREE macro, but based on xalloc.h now. Changed all callers.
3139 * src/main.c (main): Use XMALLOC macro.
3140 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
3142 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
3144 2003-09-10 Gary V. Vaughan <gary@gnu.org>
3146 Import the xalloc module from CVS gnulib, along with its
3147 dependencies: exitfail, malloc and realloc. We had different
3148 semantics for our XFREE and a function xfree() not supplied by
3149 gnulib, so also a bit of work to keep everything running
3152 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
3153 (gl_XALLOC): Use gnulib equivalents.
3154 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
3155 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
3156 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
3157 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
3159 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
3160 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
3161 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
3163 (pkgincdir): Removed. Use pkgincludedir instead.
3164 * m4/m4private.h (XFREE): xfree already checks for NULL.
3165 * m4/system_.h: Use xalloc module, and remove macros already
3166 supplied by xalloc.h.
3167 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
3168 moved the old definition from m4/xmalloc.c to here for now.
3170 2003-09-09 Gary V. Vaughan <gary@gnu.org>
3172 Import the error and progname modules from CVS gnulib. Our old
3173 error.c subsumed the functionality of both, so a little adjustment
3174 was required to accomodate the split in sources. Also added more
3175 wrapper macros to choose between a system installed error.h or our
3176 shipped gnulib error module:
3178 * m4/error.c, m4/error.h: Removed.
3179 * m4/Makefile.am: Adjust.
3180 (pkgincdir): Removed. Use pkgincludedir instead.
3181 * m4/module.h, src/main.c: Don't include `m4/error.h'.
3182 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
3184 * gnulib/m4/progname.c: Imported from CVS gnulib.
3185 * gnulib/m4/progname.h: Ditto.
3186 * src/main.c: Adjust to use progname module.
3187 * gnulib/m4/error.c: Imported from CVS gnulib.
3188 * gnulib/m4/error_.h: Ditto.
3189 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
3190 if appropriate, and link a local error.h if the system version is
3192 (libgnu_la_SOURCES) Add progname module sources.
3193 * gnulib/config/error.m4: Imported from CVS gnulib.
3194 * gnulib/config/strerror_r.m4: Ditto.
3195 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
3196 to have ERROR_H for Makefile substitutions and tell system.h
3197 whether the system error.h should be used, or a locally installed
3199 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
3201 2003-09-09 Gary V. Vaughan <gary@gnu.org>
3203 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
3204 s/gettext_.h/gettext.h/.
3206 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
3207 automake have been fixed.
3209 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
3210 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
3211 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
3212 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
3214 2003-09-09 Gary V. Vaughan <gary@gnu.org>
3216 The gnulib obstack module requires the gnulib gettext module for
3217 systems that do not have GNU gettext installed. Because we use
3218 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
3219 that directory incase it clashes with the system gettext.h. This
3220 delta uses gettext_.h and extra rules in the Makefile to make a
3221 link to gettext.h when needed:
3223 * Makefile.am (auxdir): Removed. No longer used.
3224 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
3225 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
3227 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
3228 Makefile based build.
3229 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
3230 of the macros are kept.
3231 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
3232 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
3233 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
3234 distributes these automatically.
3235 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
3236 warning from automake-1.7a.
3237 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
3238 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
3240 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
3241 wrt. m4_FUNC_OBSTACK.
3242 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
3243 wrt. m4_sys_STACKOVF.
3244 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
3245 wrt. _m4_LIB_GMP, m4_LIB_GMP.
3246 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
3247 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
3249 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
3250 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
3251 gettext.h link on deficient systems.
3252 (pkginc_HEADERS): Mention $(GETTEXT_H).
3253 (EXTRA_HEADERS): Mention gettext.h.
3254 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
3255 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
3256 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,

3266 2003-09-05 Gary V. Vaughan <gary@gnu.org>
3268 We can't mirror the gnulib directory structure here, since we need
3269 to be able to eg. `#include <m4/obstack.h>' from our source files,
3270 which is much easier if the local obstack.h is created in a
3271 directory named m4. Rather than trying to symlink everything into
3272 the m4 directory, now we build a libtool convenience library from
3273 the sources we get from gnulib and link that with libm4.la:
3275 * gnulib/config/extensions.m4: Imported from CVS gnulib.
3276 * gnulib/config/unlocked-io.m4: Ditto.
3277 * gnulib/m4/unlocked-io.h: Ditto.
3278 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
3279 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
3280 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
3281 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
3282 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
3283 * m4/Makefile.am: Adjust.
3284 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
3285 macros we redistribute.
3286 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
3287 library among others.
3288 (GNULIB_SRCS, GNULIB_MACROS): Removed.
3289 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
3290 * config/m4-obstack.m4: Adjust.
3291 * po/POTFILES.in: Adjust.
3292 * configure.ac: Reformatting. Call newly imported gnulib macros.
3293 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
3294 bogus calls of `#include "m4.h"'.
3295 * Makefile.am: INCLUDES has been deprecated in favour of
3297 * m4/Makefile.am: Ditto.
3298 * modules/Makefile.am: Ditto.
3299 * src/Makefile.am: Ditto.
3301 2003-09-05 Gary V. Vaughan <gary@gnu.org>
3303 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
3305 2003-09-04 Gary V. Vaughan <gary@gnu.org>
3307 Migrate the obstack support into the gnulib directories for easy
3308 synchronisation with upstream files in gnulib:
3310 * config/gnu-obstack.m4: Moved from here...
3311 * config/m4-obstack.m4: ...to here.
3312 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
3313 * m4/obstack.c, m4/obstack_.h: Moved from here...
3314 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
3315 * po/POTFILES.in: Adjust.
3316 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
3317 * m4/Makefile.am: Add a whole new section to link the obstack
3318 sources from the gnulib tree if necessary.
3319 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
3321 * config/m4-obstack.m4: Rewrite as a wrapper for
3322 gnulib/m4/obstack.m4.
3324 2003-09-04 Gary V. Vaughan <gary@gnu.org>
3326 GNU M4 currently builds with a number of files adapted from
3327 upstream sources. Recently the gnulib project on savannah.gnu.org
3328 has pulled together a great many of these externally maintained
3329 files. This delta is the beginnings of isolating those files
3330 maintained in gnulib to make it easy to synchronise M4 with the
3331 upstream files prior to releases.
3333 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
3335 (SUBDIRS): Added new gnulib subdirectory.
3336 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
3337 * config/stdbool.m4: Moved from here...
3338 * gnulib/m4/stdbool.m4: ...to here.
3339 * m4/stdbool_.h: Moved from here...
3340 * gnulib/lib/stdbool_.h: ...to here.
3341 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
3343 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
3344 code to work with new stdbool_.h location.
3345 (gnulib_srcdir): New.
3347 2003-09-04 Gary V. Vaughan <gary@gnu.org>
3349 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
3350 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
3352 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
3353 (EXTRA_DIST): Use it.
3355 * bootstrap: CVS autoreconf leaves file droppings. Remove
3356 aclocal.m4t incase autoreconf doesn't.
3358 2003-08-29 Gary V. Vaughan <gary@gnu.org>
3360 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
3361 the other gnulib imports, renamed to m4/obstack_.h.
3362 * m4/obstack.c: Updated from CVS gnulib.
3363 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
3364 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
3365 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
3366 about vpath already, and $top_srcdir upsets CVS Automake, so the
3367 $top_srcdir reference was removed.
3369 * m4/system-h.in: For consistency with the gnulib imports, renamed
3371 * m4/Makefile (EXTRA_HEADERS): Adjust.
3372 * configure.ac (AC_CONFIG_FILES): Adjust.
3374 * m4/stdbool_.h: New file from gnulib for systems without their
3376 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
3377 * config/stdbool.m4: New file. Macros from gnulib for same.
3378 * configure.ac: Use it.

3429 * src/main.c: Ditto.
3430 * src/stackovf.c: Ditto.
3432 * config/gmp.m4 (M4_AC_LIB_GMP): Use AC_INCLUDES_DEFAULT:
3433 ac_default_headers is an autoconf internal variable.
3434 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
3435 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
3437 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
3438 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
3441 2003-08-15 Gary V. Vaughan <gary@gnu.org>
3443 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
3445 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
3446 possible or faking one with a typedef. Changed all callers.
3448 2003-08-15 Gary V. Vaughan <gary@gnu.org>
3450 Still cleaning up the users' module API, by taking out the stuff
3451 that isn't used by any existing modules, and moving specialised
3452 functions out of libm4 and into the module they are used by.
3454 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
3455 * m4/utility.c (m4_skip_space): ...to here the home of its only
3456 use, made static and renamed to `skip_space'. Changed all
3458 * m4/m4module.h (m4_expand_ranges): Removed prototype.
3459 * m4/utility.c (m4_expand_ranges): Moved definition from here...
3460 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
3462 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
3464 * modules/gnu.c (builtin_syntax): Import and use in this
3465 builtin implementation.
3466 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
3468 * m4/macro.c (trace_flush): Except here where the macro is now
3470 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
3471 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
3473 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
3474 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
3476 2003-08-14 Gary V. Vaughan <gary@gnu.org>
3478 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
3479 compiler based AC_CHECK_HEADER that was introduced in
3481 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
3482 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
3483 * configure.ac: Use renamed M4_AC_LIB_GMP.
3485 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
3486 macro that requires arguments! This stops the shell's bad
3487 substitution error at configure time.
3489 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
3490 variables to the testsuite shell. Set the value of USE_GMP so
3491 that the gmp test will run!
3492 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
3494 2003-08-11 Gary V. Vaughan <gary@gnu.org>
3496 Libltdl already has an excellent mechanism for accessing C symbols
3497 in modules. Lets use that! Remove all the exporting cruft and
3498 just use lt_dlsym in conjunction with a few conventions to
3499 simplify module writers' jobs. Also removed the table address
3500 caching code and otherwise simplified the module loader quite a
3501 bit. To access exported symbols in other modules, first the
3502 exporting module must name the symbols <modname>_LTX_<symname>,
3503 and the importing module must define a function type called
3504 <symname>_func. The importer then adds
3505 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
3506 that wishes to call out to the exported functions. Care must be
3507 taken that <symname> is non-NULL in the importing module incase
3508 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
3509 definition was in the importers source. Study
3510 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
3511 m4_module_import will attempt to automatically load a module
3512 required for symbol access if it is not loaded already.
3514 * TODO: Removed the items fixed in this delta.
3515 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
3517 * m4/ltdl.h (lt_dlhandle_find): Declare it.
3518 * m4/module.c (m4_module_unload): Use it.
3519 * src/freeze.c (reload_frozen_state): Ditto.
3520 * m4/m4module.h (m4_export): Deleted. Removed all references.
3521 (M4_MODULE_IMPORT): New user convenience macro for importing
3522 arbitrary symbols from other modules.
3523 * m4/module.c (m4_module_import): New function to service
3524 M4_MODULE_IMPORT macro.
3525 (module_data): Removed. Looking up the tables on demand with
3526 lt_dlsym, rather than caching their addresses here simplifies the
3528 (m4_get_module_builtin_table, m4_get_module_macro_table):
3529 Removed. Changed all callers.
3530 (set_module_macro_table, set_module_builtin_table): Renamed to
3531 install_macro_table and install_builtin_table respectively, and
3532 simplified now that the cache is no more.
3533 * modules/gnu.c (builtin_symbols): Use this new mechanism to
3534 import m4_dump_symbols from the m4 module.
3535 (builtin_esyscmd): Likewise for m4_set_sysval and
3537 * modules/m4.c (m4_export_table): Removed. Functions are
3538 addressed with the new mechanism which doesn't need this.
3539 (m4_set_sysval): New exported accessor function to prevent
3540 problems with variable access on inferior architectures.
3541 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
3542 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
3543 that we can have some type safety.
3544 * modules/modtest.c (export_test): C level exported function for
3545 testing the new import mechanism.
3546 * modules/import.c: New file for the import end of the test.
3547 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
3548 * tests/modules.at: New test cases for intermodule symbol
3551 2003-08-07 Gary V. Vaughan <gary@gnu.org>
3553 * m4/m4module.c (m4_string): Moved from here...
3554 * m4/m4private.c (m4_string): ...to here.
3556 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
3558 2003-07-29 Gary V. Vaughan <gary@gnu.org>
3560 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
3561 already available to module writers through
3562 m4_{get,set}_nesting_limit_opt(), so moved from here...
3563 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
3564 (m4_create): Use it.
3566 2003-07-28 Gary V. Vaughan <gary@gnu.org>
3568 Aside from auditing path.c for m4module.h api obfuscation, this
3569 delta introduces the concept of private struct members in opaque
3570 data types to GNU m4: See the STYLE file for details.
3572 * TODO: Remind ourselves that a rewrite of path.c is needed.
3573 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
3575 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
3576 here and renamed. These type definitions are for internal api use
3577 only. Changed all callers.
3578 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
3580 * m4/path.c (search_path_env_init, search_path_add): ...to here
3581 and renamed. These calls were never used outside this file.
3582 Changed all callers.
3583 (dirpath): Moved functionality of this static declaration...
3584 * m4/m4private.h (struct m4): ...to this new internal only
3585 search_path field. Changed all callers.
3586 (m4__get_search_path): Added new internal api accessor.
3587 * m4/path.c (m4_search_path_info_new): Removed. Not used.
3588 (m4_include_init): Removed...
3589 * m4/m4.c (m4_create): ...because the new m4 field is now
3591 (m4_delete): Recycle search_path memory.
3592 * src/main.c (main): Don't call m4_include_init now that it's
3594 * doc/STYLE: Document convention for private fields in opaque
3597 2003-07-24 Gary V. Vaughan <gary@gnu.org>
3599 Sometimes exporting the address of a symbol from a module isn't
3600 enough for other modules to call that symbol correctly. If
3601 custom data types are used for function parameters, they need to
3602 be known to the caller. This change introduces the concept of
3603 $(prefix)/include/modules/$(modulename).h to declare those
3604 structures. Also we move m4_dump_symbols from libm4 to the m4
3605 module to show this concept in action.
3607 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
3608 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
3609 exporting data structures from modules/m4.c.
3610 * modules/m4.c, modules/gnu.c: Include it.
3611 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
3612 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
3614 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
3616 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
3617 ...to here, with slight renaming.
3618 (m4_export_table): Prototype and add m4_dump_symbols.
3619 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
3620 definition of m4_dump_symbols.
3621 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
3622 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
3624 2003-07-24 Gary V. Vaughan <gary@gnu.org>
3626 Create an export table in modules/m4.c in readiness for beefing up
3627 the module loader to track module exports and imports.
3629 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
3630 * m4/debug.c (m4_debug_flush_files): Moved...
3631 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
3632 * modules/gnu.c (builtin_esysval): Use it.
3633 * m4/m4module.h (m4_export): New type for declaring module symbols
3635 * modules/m4.c (m4_export_table): List symbols exported from this
3636 module for use by other modules.
3638 2003-07-24 Gary V. Vaughan <gary@gnu.org>
3640 An experiment: There is loads of code in libm4 which should be in
3641 the m4 module, but is also used by another module. Just because
3642 some linkers won't cope with calls across dynamic runtime loaded
3643 objects I initially left the code in libm4. It will tidy the
3644 module api immensely if this code moves to the right place, I just
3645 need to remember to invent a suitable calling mechanism at some
3646 point. For now, only modules that are statically linked and
3647 preloaded will get this treatment, so the only platforms that will
3648 break are those that require all symbols to be resolved at link
3651 * TODO: Reminder that what I am doing could reduce portability
3652 unless I do something more robust later.
3653 * m4/m4module.h (m4_sysval): No longer exported from libm4.
3654 * m4/utility.c (m4_sysval): No longer declared in libm4.
3655 * modules/Makefile.am: Reformatting.
3656 * modules/m4.c (m4_sysval): Declare it at place of use.
3657 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
3659 2003-07-23 Gary V. Vaughan <gary@gnu.org>
3661 * m4/m4module.h: Reformatting and rearranging lines a bit.
3662 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
3664 (m4_call_macro, m4_expand_input): Renamed...
3665 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
3667 (m4_expansion_level, m4_process_macro): Moved...
3668 * m4/macro.c (expansion_level, process_macro): ...to here, and
3671 * m4/m4module.h (program_name): Not used by modules at all, so
3673 * src/main.c (program_name): ...to here.
3674 (print_program_name): Renamed...
3675 (print_program_name_CB): ...to conform to the STYLE guide.
3677 2003-07-23 Gary V. Vaughan <gary@gnu.org>
3679 More refactoring of the m4module.h API. Replace #defines with an
3680 enum, and move non-public functions out of the public API.
3682 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
3684 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
3685 * m4/debug.c (m4_debug, trace): Moved...
3686 * m4/m4private.h (struct m4): ...to fields of this struct.
3687 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
3689 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
3690 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
3691 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
3692 * m4/m4module.h (m4_context_field_table): Add entries for new
3693 debug_file and trace_messages fields.
3694 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
3695 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)

3702 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
3704 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
3705 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
3706 * m4/macro.c (trace_format, trace_header, trace_flush)
3707 (trace_prepre, trace_pre, trace_post): ...to these newly static
3708 functions, since they are only ever used from this file. Changed
3711 2003-07-17 Gary V. Vaughan <gary@gnu.org>
3713 Change the macros for checking syntax so that matching against
3714 multiple possible syntax classes can be done with a single
3715 comparison some of the time. The various classes are now bits of
3716 an int that can be checked with bitwise logic operators.
3718 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
3719 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)

3729 Replace all calls with invocations of these...
3730 (m4_is_syntax, m4_has_syntax): ...New macros.
3731 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
3732 is no longer required with new macros. Changed all callers.
3734 2003-07-15 Gary V. Vaughan <gary@gnu.org>

3740 * m4/macro.c (expand_token): Check for out of range
3741 m4_peek_input() results before looking up in the syntax table.
3742 (collect_arguments): Ditto.
3744 * NEWS: Note `$' syntax class.
3746 2003-07-08 Paul Eggert <eggert@twinsun.com> and
3747 Gary V. Vaughan <gary@gnu.org>
3749 Conform to POSIX if the POSIXLY_CORRECT environment is set.
3750 --traditional `define' now smashes all the definitions.
3752 * NEWS: Explain this.
3753 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
3754 (Extensions): Explain that extensions that are incompatible with
3755 POSIX are disabled if POSIXLY_CORRECT is set.
3756 (Incompatibilities): Remove.
3757 (Define, Other Incompat): Explain difference
3758 between GNU and POSIX behavior of define, pushdef, popdef.

3786 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
3787 by using the new M4__IS_STRING macro.
3788 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
3789 variable references in macro expansions.
3791 * doc/m4.texinfo (Eregexp and Regexp): Typo.
3792 (Epatsubst and Patsubst): Typo.
3795 2003-06-26 Gary V. Vaughan <gary@gnu.org>
3797 Move the global variables that pertain to syntax to a new `struct
3798 m4_syntax_table', and then add one of these to `struct m4'. The
3799 ripple effect through the code to both change formerly global
3800 references, and make sure a suitable context is available in
3801 lexical scope is disproportionately large compared to the size of
3802 the change proper. This change is a large part of decoupling
3803 syntax.c from the rest of the code that uses it.
3805 * m4/m4private.h (struct m4): Add a syntax field.
3806 * m4/m4.c (m4_create): Initialise it,
3807 (m4_delete): Recycle it.
3808 (m4_get_symtab): Remove hand coded version...
3809 (m4_get_symbol_table): ...and generate this with cpp. Changed all
3811 * m4/m4module.h (m4_context_field_table): Add an extra field so we
3812 can generate m4_get_symbol_table. Add a new row for
3813 m4_get_syntax_table.
3814 (M4SYNTAX): Syntactic sugar for module writers.
3815 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
3816 (m4_syntax_table): New home for syntax related formerly global
3818 * m4/m4private.h (struct m4_syntax_table): Define it.
3819 * m4/input.c (m4_input_init): Initialisation of these formerly
3820 global variables moved...
3821 * m4/syntax.c (m4_syntax_create): ...to here.
3822 * m4/input.c (m4_input_exit): And similarly, recycling of the
3823 memory used by those values moved...
3824 * m4/syntax.c (m4_syntax_delete): ...to here.
3825 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
3826 Moved to m4/m4private.h.
3827 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
3828 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
3829 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
3830 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
3831 objects. Changed all callers that used to directly access the
3833 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
3834 Removed and incorporated into m4_syntax_table structure.
3835 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
3836 * m4/syntax.c (m4_set_syntax): Now returns an error status,
3837 instead of requiring a `struct m4' to generate its own errors.
3838 Changed all callers.
3839 * src/main.c (main): Now that the syntax table is initialised as
3840 part of m4_create, we have to manually wipe the syntax entries if
3841 we are about to read a frozen file.
3843 2003-06-26 Gary V. Vaughan <gary@gnu.org>
3845 * doc/STYLE: Added notes on callback naming schemes.
3847 * m4/module.c (m4_set_module_macro_table)
3848 (m4_set_module_builtin_table): Declarations weren't changed when
3849 definitions were renamed on 2003-06-19.
3851 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
3852 neither used nor particularly appropriate since it exposes the
3853 internal workings of the hash module. I haven't yet decided
3854 whether to remove it entirely.
3856 2003-06-20 Gary V. Vaughan <gary@gnu.org>
3858 Two related changes, and a huge knockon effect throughout the
3859 source: Moved the option variables out of global space and into
3860 `struct m4'; made `m4_symtab' a real datatype, so that its api
3861 is not marred passing `struct m4' around just so it can decide
3862 whether to keep traced symbol names or not. Added setters and
3863 getters for the formerly global option variables, and obviously
3864 changed a vast number of functions to take a `struct m4' and use
3865 the getter funcs to find option values.
3867 * m4/utility.c (interactive, sync_output, debug_level)
3868 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
3869 (max_debug_argument_length, warning_status, nesting_limit)
3870 (discard_comments): Removed.
3871 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
3872 (debug_level, max_debug_argument_length, prefix_all_builtins)
3873 (suppress_warnings, discard_comments, interactive, sync_output):
3874 Removed from here...
3875 * m4/m4private.h (struct m4): ...and equivalent fields added to
3877 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
3878 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
3879 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
3880 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
3881 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
3882 macros for the new fields.
3883 * m4/m4module.h (m4_context_field_table)
3884 (m4_context_opt_bit_table): Helper macros used to generate
3885 prototypes, setters and getters for new option fields
3887 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
3888 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
3889 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
3890 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
3891 (m4_get_interactive_opt, m4_get_sync_output_opt)
3892 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
3893 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
3894 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
3895 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
3896 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
3897 setter and getter functions generated by cpp from
3898 m4_context_field_table and m4_context_opt_bit_table, exported as
3899 part of the module api. Changed all callers.
3900 * m4/symtab (struct m4_symtab): Used as the concrete type for
3902 (m4_symtab_create): Allocate and initialise a new struct.
3903 (m4_symtab_apply): New function that works like m4_hash_apply, but
3904 with different callbacks specific to symbol tables. Changed all
3906 (symbol_destroy, arg_destroy, arg_copy): Renamed
3907 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
3908 they have unused parameters for a reason!
3909 (dump_symbol_CB): New callback to dump the contents of a single
3911 (symtob_dump): Rewritten in terms of dump_symbol_CB.
3912 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
3913 Changed all callers.
3914 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
3915 of the contained `m4_symtab' at the `no_gnu_extensions' field.
3916 Although I'm not convinced these semantics are correct, they are
3917 at least consistent with how things were before this delta. Also
3918 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
3920 2003-06-19 Gary V. Vaughan <gary@gnu.org>
3922 Tie down the interface to libm4 some more. Make more structures
3923 opaque to modules by moving them to m4private.h, and writing
3924 setters and getters. To win back the speed penalty for doing this
3925 also wrote macroized versions that do know about structure layout
3926 in m4private.h and #include that file into modules when NDEBUG is
3927 defined at compile time. There are still some accessor macros in
3928 m4private.h that need to go, but that is not necessary to clean
3931 * m4/m4module.h (m4_symbol_type): Moved...
3932 * m4/m4private.h (m4__symbol_type): ...to here.
3933 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
3934 (m4_set_symbol_traced, m4_set_symbol_name_traced)
3935 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
3936 (m4_get_symbol_func, m4_symbol_value_create)
3937 (m4_symbol_value_delete, m4_set_symbol_value_text)
3938 (m4_set_symbol_value_func): New exported api to symbols.
3939 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
3940 and m4_is_symbol_value_func.
3941 * m4/m4module.h: Prototype these guys.
3942 * m4/module.c (m4_set_module_macro_table)
3943 (m4_set_module_builtin_table): Make these static, there is no
3944 reason to pollute the api with them.
3945 * m4/m4private.h: Reformatting.
3946 (m4_get_symtab): Only define when NDEBUG is defined.
3947 (m4_get_symbol_value, m4_get_symbol_traced)
3948 (m4_set_symbol_traced, m4_set_symbol_name_traced)
3949 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
3950 (m4_get_symbol_func, m4_symbol_value_create)
3951 (m4_symbol_value_delete, m4_set_symbol_value_text)
3952 (m4_set_symbol_value_func): Macro implementations of the new
3953 functions when NDEBUG is defined.
3954 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
3955 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
3956 Superceded by the above. All callers changed.
3957 (M4ARG): Removed. This is no longer different to the
3958 m4/m4module.h definition.
3959 * modules/gnu.c, modules/m4.c: Only include m4private.h when
3960 NDEBUG is defined. That way we exercise the same (albeit slower)
3961 api that external modules must use.
3963 2003-06-18 Gary V. Vaughan <gary@gnu.org>
3965 Renamed some of the types and their accessors to make more sense.
3966 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
3967 has a stack of SYMBOL_VALUEs.
3969 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
3970 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
3971 m4_get_symbol_value_type, m4_get_symbol_value_text,
3972 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
3973 Changed all callers.
3974 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
3975 (m4_get_token_type): Renamed
3976 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
3977 to the internal api.
3978 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
3980 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
3981 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
3982 (m4__token_type): Moved here from m4module.h.
3983 (m4__next_token): Renamed from m4_next_token.
3984 * m4/symtab.c: Removed some of the parameterised macro support
3985 functions for modularisation later.
3986 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
3987 m4_hash_dup to perform a true deep copy of the SRC.
3988 (arg_copy): Callback for m4_symbol_value_copy.
3989 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
3990 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
3991 m4_get_symbol_value_func. Changed all callers.
3993 2003-06-18 Gary V. Vaughan <gary@gnu.org>
3995 Tidy up style of hash.[ch] in accordance with doc/STYLE.
3997 * m4/hash.c: Internal symbol renaming and formatting.
3998 (m4_hash_dup): New function to facilitate deep copies of hash
4000 (m4_hash_apply_func): Returns a void* now, which is a richer type
4001 for returning exceptions (NULL means keep going).
4002 (m4_hash_apply): Ditto.
4003 * m4/hash.h: Declare exported symbols with an explicit extern.
4006 2003-06-17 Gary V. Vaughan <gary@gnu.org>
4008 Still refactoring furiously. This delta represents a change in
4009 semantics to symtab.c. Instead of building temporary m4_tokens
4010 in the caller, and copying fields in the methods, we now create
4011 the actual m4_token for hashing in the caller so the methods just
4012 slot them in directly. Also, this means that we don't lookup a
4013 symbol and get back an allocated but VOID token to copy fields
4014 into, we create the token we want to push and pass that to
4015 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
4016 a few other small changes to stop knowledge of the implementation
4017 of symtab.c leaking out into other files.
4019 * m4/macro.c (expand_argument): Comment typo corrected.
4020 * m4/symtab.c (symtab_fetch): New function to fetch the address of
4022 (m4_symbol_pushdef): Take an extra value parameter and use this
4023 directly as the new top of the value stack. All callers changed
4024 to build a token and pass responsibility for memory in, rather
4025 than copying as we used to.
4026 (m4_symbol_define): Also use the new value parameter directly as a
4027 replacement for the top of the value stack. All callers changed
4028 to build a token as above.
4029 (m4_set_symbol_traced): New function to set the traced bit on the
4030 named symbol, creating it if necessary.
4031 (symbol_popval): The guts of the old m4_symbol_popdef.
4032 (m4_symbol_popdef): Use it.
4033 * m4/builtin.c (m4_symbol_set_token): Removed,
4034 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
4036 * m4/module.c (m4_set_module_builtin_table)
4037 (m4_set_module_macro_table): ...with these more orthogonal
4039 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
4040 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
4042 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
4043 (m4_arg_signature_parse): Moved...
4044 * m4/symtab.c: ...to here.
4045 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
4046 screw something up. Moved...
4047 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
4048 actually does a proper deep copy of source to dest.
4050 2003-06-16 Gary V. Vaughan <gary@gnu.org>
4052 Further refactoring to stabilise the module API. Renaming some
4053 functions for orthogonality, and judicious definition migration to
4054 move things out of the set of exported symbols.
4056 * doc/STYLE: New file. Notes on coding style.
4057 * m4/m4module.c: Updated bitrotted docucomment at the top of the
4059 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
4060 m4_get_module_name, m4_get_module_builtin_table,
4061 m4_get_module_macro_table which are verb phrases. Changed all
4063 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
4065 * m4/module.c (m4_set_module_builtin_table)
4066 (m4_set_module_macro_table): ...here, and renamed. Changed all
4068 * m4/m4module.c (m4_module_data): This...
4069 * m4/m4private.c (struct m4_module_data): ...and this...
4070 * m4/module.c (module_data) ...consolidated here and no longer
4071 exported. Changed all callers.
4073 2003-06-16 Gary V. Vaughan <gary@gnu.org>
4075 Begin work on lifting the curse of the global variables. To start
4076 with create a `struct m4' context container, and replace
4077 `m4__symtab' with `context->symtab' throughout. This means
4078 initialising a context container in main, and adjusting many
4079 functions between main and the module entry points so that the
4080 container gets passed through. It would have been nice to
4081 defer this until after 1.5, but it has a major effect on the
4082 user's module writing ABI, so it needs to be addressed now - at
4083 least in the areas that impact the ABI. An interrelated change
4084 in the symtab API removes the dependency on a global symbol table,
4085 and instead focuses on a passed table (from the context
4088 * TODO: Reminders for finishing context functionality.
4089 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
4090 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
4091 global variables and eventually allow m4 to be reentrant.
4092 * m4/m4private.h (m4): Define the new structure here...
4093 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
4094 don't carry the overhead of a function call.
4095 * m4/m4module.h: Prototype extern functions from m4/m4.c.
4096 (m4): Declare type for new struct m4 objects.
4097 (M4SYMTAB): User macro to ease finding the symbol table for the
4098 current context for module developers.
4099 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
4101 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)

4103 (m4_call_macro, m4_dump_symbols, m4_expand_input)

4105 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
4106 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
4107 m4* context parameter. Changed definitions and all callers.
4108 (m4_symtab): Alias for m4_hash to decouple the
4109 m4_symtab api from m4_hash.
4110 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
4112 (m4_symtab_create): New function to return an initialised
4114 (m4_symtab_delete): New function to delete an m4_symtab's memory.
4115 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
4116 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
4117 instead of simply using the global m4__symtab. Changed
4118 definitions and all callers.
4119 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
4120 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
4121 * src/main.c (main): Create a context and use that instead of the
4122 former global m4__symtab.
4124 2003-06-13 Gary V. Vaughan <gary@gnu.org>
4126 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
4127 to the callback. Callbacks should not need to hardcode the
4128 hashtable they are working from, nor should we have to waste the
4129 userdata parameter to pass the table in.
4130 * m4/hash.h (m4_hash_apply_func): Require the initial table
4132 * m4/symtab.c (symtab_destroy): Use the passed table instead
4133 of hardcoding m4__symtab.
4134 (m4_symbol_popdef): Don't use the userdata parameter to pass the
4135 table to arg_destroy.
4136 (arg_destroy): Use the hash parameter, ignore userdata.
4137 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
4139 (traceon, traceoff): Call set_trace with the extra initial
4142 2003-06-13 Gary V. Vaughan <gary@gnu.org>
4144 More refactoring to stabilise the module api, this time for
4145 symtab.c. Additionally, start to pay attention to function names
4146 that don't contain a verb like they should.
4148 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
4149 wrapper for m4_hash_apply to decouple the symtab module from the
4151 (m4_symbol_builtin, m4_symbol_macro): Renamed to
4152 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
4154 (m4_symbol_delete): Create a macro version to save a function
4156 (m4_token_t, m4_data_t): These violate the POSIX reserved
4157 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
4159 (m4_token_type): Renamed to m4_token_get_type.
4160 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
4161 (m4_symtab_exit): Removed from the exported module
4163 * m4/m4private.h (m4__symtab, m4__symtab_init)
4164 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
4165 renamed and added to the internal api. Changed all callers.
4166 (m4_symtab_apply): A faster macro version of the function for
4167 users of the internal api.
4168 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
4169 symbol_destroy and arg_destroy.
4170 (symtab_debug): Added a prototype.
4171 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
4172 so that callers in this file get the faster macro versions from
4175 2003-06-12 Gary V. Vaughan <gary@gnu.org>
4177 Refactoring modules to rationalise the API into an external
4178 documented (eventually!) API for use by modules in the `m4_'
4179 namespace declared in m4/m4module.h, an internal API between the
4180 source files we ship (including our shipped modules) in the `m4__'
4181 namespace declared in m4/m4private.h and making the rest as
4182 cohesive as possible with liberal use of the `static' keyword.
4183 This change represents an audit to m4/module.c along these
4186 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
4187 Removed. No longer used.
4188 (m4_module_close): Removed prototypes.
4189 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
4190 from the exported module api...
4191 * m4/m4private.h (m4__module_init, m4__module_open)
4192 (m4__module_exit): ...and renamed and added to the internal api.
4193 Changed all callers.
4194 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
4195 Centralised definitions after renaming...
4196 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
4197 (M4_FINISH_SYMBOL): ...and removing from here.
4198 (m4_module_dlerror, m4_module_remove, m4_module_close)
4199 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
4200 module_remove, module_close and caller_id.
4201 (MODULE_SELF_NAME): New macro to make reporting self errors
4203 (m4_module_load, module_close, module_remove): Use it.
4204 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
4206 * src/main.c (main): Use it.
4208 2003-06-12 Gary V. Vaughan <gary@gnu.org>
4210 * README: Remove references to --enable-changeword, which has been
4211 removed from the code.
4213 2003-06-11 Gary V. Vaughan <gary@gnu.org>
4215 Getting rid of the annoying bug with configure --enable-debug,
4216 which spewed -e: command not found errors. This was an interaction
4217 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
4218 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
4219 branch-1-5) to get the full fix.
4221 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
4222 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
4223 and then use the probed value of $SED.
4224 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
4225 this, it messes up the AC_REQUIRE stack.
4227 2003-06-10 Gary V. Vaughan <gary@gnu.org>
4229 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
4230 the destroy callback.
4231 (m4_arg_destroy): Use the hash address to free the hash node key
4234 2003-06-06 Gary V. Vaughan <gary@gnu.org>
4236 First cut at formal parameters in macros.
4238 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
4239 * m4/xstrzdup.c: New file.
4240 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
4241 associative array of parameter names to details.
4242 (m4_symbol_token): Capture macro names with parameter lists.
4243 (m4_arg_signature_parse): And build an associative array to hang
4244 from the symbol structure to map names to details.
4245 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
4246 m4_hash_resize idiom. Now that we potentially add a little hash
4247 table to many of the entries in the symbol table, added an extra
4248 arg to set the initial size. Changed all callers.
4249 (m4_hash_apply): New function that is basically a generalised
4251 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
4252 all callers to call m4_hash_apply instead.
4253 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
4254 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
4255 m4_arg_signature association that might be attached to the symbol,
4256 * m4/hash.h (m4_hash_apply_func): Replacement type for...
4257 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
4258 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
4260 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
4261 (M4_IS_IDENT): Detect characters that can be safely used in
4263 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
4264 * m4/macro.c: Corrected grammar in some comments. Use `token'
4265 rather than `td' for m4_token variables.
4266 (m4_process_macro): If we find a dollar followed by some
4267 M4_IS_IDENT characters, replace that with the contents of the argv
4268 entry with offset stored in the m4_token_arg associated with the
4269 collected identifier.
4271 2003-06-05 Gary V. Vaughan <gary@gnu.org>
4273 Begin preparations for supporting formal parameters in m4 macros.
4275 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
4276 the details of a formal parameter.
4277 (m4_token): Add an arg_signature member to hold a hash table for
4278 looking up formal parameters.
4279 * m4/input.c: Update more bitrotted comments.
4280 (m4_push_builtin): Initialise arg_signature member.
4281 (init_builtin_token): Copy arg_signature member.
4282 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
4283 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
4285 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
4286 (m4_macro_pushdef, m4_macro_define): ...these, And...
4287 (m4_symbol_token): ...wrapped around this new function, which
4288 vastly simplifies the arguments required by the functions it
4290 Changed all callers.
4292 2003-06-05 Gary V. Vaughan <gary@gnu.org>
4294 * m4/macro.c: Format changes.
4296 2003-06-04 Gary V. Vaughan <gary@gnu.org>
4298 * m4/input.c: Updated various bitrotted comments.
4299 (m4_push_builtin): Just pass the whole m4_token, rather than
4300 extracting all the fields in the caller. This also allows us to
4301 check the token type for consistency.
4302 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
4303 Renamed to builtin_funcs, builtin_peek, builtin_read,
4304 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
4305 the code. Changed all callers.
4306 (struct input_block): Similarly renamed u_m member to u_b, and
4307 changed all callers.
4308 (m4_next_token): Use bzero to initialise the data fields.
4309 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
4311 2003-05-29 Gary V. Vaughan <gary@gnu.org>
4313 These changes were necessary to get m4 to build on my iBook
4314 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
4315 (GCC) 3.1 20020420 (prerelease)":
4317 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
4318 inclusion of module loader headers.
4319 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
4320 * m4/Makefile.am: Ditto.
4321 (libm4_la_LIBADD): Added $(LTLIBINTL).
4322 * m4/utility.c (program_name): Removed declaration in favour of
4323 the one already in error.c!
4324 * m4/m4module.h (program_name): Define to program_invocation_name
4325 when using GNU C library. Use an explicit extern declaration.

4336 (m4_current_line, m4_current_diversion, m4_output_current_line):
4337 Don't rely on default, use an explicit extern.
4338 * m4/error.h (error, error_at_line, error_print_progname)
4339 (error_message_count, error_one_per_line): Ditto.
4340 * m4/ltdl.c: Update from CVS libtool.
4342 * commit: Update from CVS cvs-utils.

4355 2002-11-04 Akim Demaille <akim@epita.fr>
4357 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
4359 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
4361 2002-11-04 Akim Demaille <akim@epita.fr>
4363 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
4365 2002-11-04 Akim Demaille <akim@epita.fr>
4367 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
4368 used as `external', and Libtool 1.4.3.
4370 (LTLIBOBJS): Don't play with it.
4372 * Makefile.am (SUBDIRS): Remove intl.
4373 (ACLOCAL_AMFLAGS): Add -I config.
4374 (EXTRA_DIST): Add config/config.rpath.
4377 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
4379 2002-05-29 Gary V. Vaughan <gary@gnu.org>
4381 Preparations for refactoring syntax tables to allow reverse
4382 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
4383 speed of normal lookups in an array of unsigned short.
4385 * m4/input.c (single_quotes, single_comments, use_macro_escape):
4387 * m4/m4private.h (m4__single_quotes, m4__single_comments,
4388 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
4389 is for internal symbols which unavoidably pollute the global
4390 namespace, but are not published APIs.
4391 Adjusted all callers.
4392 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
4393 m4_set_comment, m4_set_syntax, set_syntax_internal,
4394 unset_syntax_attribute): Moved from this file...
4395 * m4/syntax.c: New. ...to this file.
4396 Also added an m4_syntax_exit stub for orthogonality.
4397 * src/main.c (main): Use it.
4398 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
4399 * m4/m4module.h: Reformatting. New prototypes.
4401 2002-05-29 Gary V. Vaughan <gary@gnu.org>
4403 * bootstrap (aclocal_apiversion): The aclocal apiversion is
4404 distinct from the automake release number (in that the apiversion
4405 apparently has no micro-version-component).
4406 (aclocal_apilibdir): Use it.
4408 2002-05-28 Gary V. Vaughan <gary@gnu.org>
4410 * m4/hash.c (m4_hash_resize): New function.
4411 * m4/hash.h: Add prototype.
4412 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
4413 benchmarking to find a good value for, say, autoconf. This is
4414 already a little quicker than before for me.
4416 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
4417 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
4419 * m4/hash.h: Adjust prototypes.
4421 2002-01-22 Akim Demaille <akim@epita.fr>
4423 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
4425 * tests/Makefile.am (package.m4): New.
4426 * tests/atlocal.in: Adjust to CVS Autotest.
4427 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
4428 * configure.ac: LIBOBJ is a forbidden string.
4429 Simplify AM_INIT_AUTOMAKE invocation.
4430 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
4433 2002-01-21 gettextize <bug-gnu-utils@gnu.org>
4435 * po/Makefile.in.in: Upgrade to gettext-0.10.40.
4437 2001-10-19 Akim Demaille <akim@epita.fr>
4439 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
4441 2001-10-19 Akim Demaille <akim@epita.fr>
4443 * m4/input.c (m4_next_token): Display where was opened what is
4446 2001-10-19 Akim Demaille <akim@epita.fr>
4448 * m4/macro.c (expand_argument): Display where was opened what is
4451 2001-10-18 Akim Demaille <akim@epita.fr>
4453 * m4/input.c, modules/m4.c: Formatting changes.
4455 2001-10-17 Gary V. Vaughan <gary@gnu.org>
4457 * bootstrap: s/configure.in/configure.ac/
4459 2001-10-16 Gary V. Vaughan <gary@gnu.org>
4461 * m4/symtab.c (m4_symbol_destroy): This function calls
4462 m4_symbol_popdef, which recycles a symbols memory when the last
4463 definition is popped. Since we were passing the address of the
4464 symbol name found in the symbol table, and it was being removed
4465 partway through m4_symbol_destroy() we were referencing freed
4466 memory for the balance of the function. Now we take a copy of the
4467 symbol name tring and use that as a key into the symbol
4468 table... that way if the original symbol name is freed, the copy
4471 2001-10-13 Akim Demaille <akim@epita.fr>
4473 * m4/ltdl.c: Update.
4475 2001-10-13 Akim Demaille <akim@epita.fr>
4477 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
4478 Don't gettextize internal error messages.
4480 2001-10-13 Akim Demaille <akim@epita.fr>
4482 * tests/macros.at (Arity and defn): New failing test.
4483 (Arity, defn, and freeze): New.
4485 Fix `Arity and defn'.
4487 * m4/input.c (m4_push_macro): Don't forget the arity.
4488 * modules/m4.c (defn): Likewise.
4490 2001-10-13 Akim Demaille <akim@epita.fr>
4492 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
4494 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
4495 (Propagation of traceon, Propagation of --trace): this new file.
4497 2001-10-13 Akim Demaille <akim@epita.fr>
4499 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
4500 interface instead of (name, argc...).
4501 Upon failure, specify which argument was guilty.
4504 2001-10-13 Akim Demaille <akim@epita.fr>
4506 * modules/evalparse.c: Save translators' time: don't translate
4507 internal error messages.
4508 (m4_evaluate): Simplify/normalize error messages.
4509 * doc/m4.texinfo (Eval): Adjust.
4511 2001-10-13 Akim Demaille <akim@epita.fr>
4513 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
4514 where no checking is needed.
4515 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
4516 interface instead of (name, argc...).
4518 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
4521 2001-10-13 Akim Demaille <akim@epita.fr>
4523 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
4524 exclude the builtin name from the count.
4525 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
4526 calling ifelse with a single argument is valid.
4527 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
4528 with 1 and 2 args, mostly to strengthen the test suite.
4530 2001-10-13 Akim Demaille <akim@epita.fr>
4532 * m4/output.c (m4_make_diversion, m4_insert_file)
4533 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
4535 2001-10-12 Gary V. Vaughan <gary@gnu.org>
4537 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
4538 since we call these things builtins in the rest of the code!
4540 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
4542 2001-10-12 Gary V. Vaughan <gary@gnu.org>
4544 Rather than forcing each builtin definition to manage its own
4545 argument range checking, tabulate the maxima and minima for all
4546 builtins in each module. This forces us to consider what the
4547 valid ranges for each builtin should be, and moves the checking
4548 code out of each builtin implementation and into the builtin
4549 caller infrastructure.
4551 * m4/m4module.h (struct m4_builtin): Add argument minima and
4553 * m4/m4private.h (struct m4_token): Reflect them here too.
4554 * m4/input.c (struct input_block): ...and here.
4555 (m4_token_copy): New function for token copying.
4556 (init_macro_token): Copy them from a token to the input stack.
4557 (m4_next_token): Don't forget to initialise them for text
4559 * m4/macro.c (expand_argument): Use m4_token_copy, and also
4560 check argument counts before calling the builtin handler.
4561 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
4562 (m4_symbol_macro): Likewise.
4563 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
4564 parameters. Updated all callers.
4565 (m4_builtin_define): Ditto.
4566 (m4_macro_pushdef, m4_macro_define): Ditto.
4567 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
4568 * modules/evalparse.c: Declare argument counts for defined
4569 builtins and remove explicit calls to m4_bad_argc().
4570 * modules/gnu.c: Ditto.
4571 * modules/load.c: Ditto.
4572 * modules/m4.c: Ditto.
4573 * modules/modtest.c: Ditto.
4574 * modules/mpeval.c: Ditto.

4578 * modules/time.c: Ditto.

4583 The trace semantics now attach the trace bit to a symbol name.
4584 For as long as a traceon(`foo') is active, calls to foo will be
4585 traced regardless of intervening undefines or module unloads.
4586 Fixed the flag propogation issues differently to the fixes
4587 reverted with the last attempt at nailing down trace:
4589 * m4/m4private.h: This file is not visible outside of the m4
4590 source tree, so I removed all the `M4_' and `m4_' prefixes to save
4591 on typing. Updated all clients.
4592 (m4_token): New typedef contains the fields that need to be passed
4593 around with the low level tokeniser.
4594 (m4_token_data): Removed.
4595 (m4_symbol): Now contains the traced flag again.
4596 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
4597 the trace bit set. This change is contained entirely within this
4598 module and doesn't leak out into the callers. Updated all
4600 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
4601 new fields in m4_token. Updated all clients.
4602 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
4603 that `groks_macro_args' and `blind_if_no_args' flags are retained
4604 when defn() results are passed around in m4 code. Updated all
4606 (m4_builtin_define): Ditto.
4607 (m4_macro_pushdef, m4_macro_define): Ditto.
4608 * m4/input.c (struct input_block): Add a flags field to facilitate
4610 (m4_push_macro): ...use it.
4611 (init_macro_token): Retrieve it.
4612 (m4_next_token): Initialise it.
4613 * m4/macro.c (expand_argument): Copy it.
4614 * m4/m4module.h: Adjust.
4615 * tests/builtins.at: Adjust the expected output of the trace
4616 tests to reflect the change in semantics.
4617 * tests/modules.at (modules: trace): Check that unloading a
4618 module which supplies a traced symbol definition doesn't lose te
4621 2001-10-07 Gary V. Vaughan <gary@gnu.org>
4623 * modules/gnu.c (m4_macro_table): Display the timetamp when
4624 expanding __m4_version__.
4626 * configure.ac (--with-modules): Forgot a comma in the
4627 AC_HELP_STRING parameter list.
4629 2001-10-05 Gary V. Vaughan <gary@gnu.org>
4631 * bootstrap: Remove aclocal.m4t when it is no longer required.
4633 2001-10-05 Akim Demaille <akim@epita.fr>
4635 * tests/Makefile.am: Adjust for gnuprog2.
4636 * tests/m4.in: There can be a leading path.
4637 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
4638 * tests/testsuite.at: Adjust to the most recent Autotest.
4639 (AT_CHECK_M4_FILTER): Fix and rename as...
4641 * tests/others.at: Use it.
4643 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
4644 variable in shell scripts, one uses `$'...
4646 2001-10-04 Gary V. Vaughan <gary@gnu.org>
4648 * configure.ac: `rm -f $m4_getopt_h' was lost.
4650 2001-10-04 Gary V. Vaughan <gary@gnu.org>
4652 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
4653 time. Define it for config.h in order to...
4654 * src/main.c (main): ...display the timestamp for --version.
4656 2001-10-04 Akim Demaille <akim@epita.fr>
4658 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
4659 previous builtins `regexp' and `patsubst'.
4660 (regexp, patsubst): Use them.
4661 (eregexp, epatsubst): New builtins.
4662 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...

4664 (Extensions): More info on REs.
4666 2001-10-04 Akim Demaille <akim@epita.fr>
4668 * modules/modtest.c (init_handler): Consistently output to stderr.
4669 (finish_handler): New.
4670 (test): The `if' is an `assert'.
4671 * tests/modules.at: Adjust.
4673 2001-10-04 Akim Demaille <akim@epita.fr>
4675 * m4/utility.c (m4_bad_argc): Detail the mismatches.
4677 2001-10-01 Akim Demaille <akim@epita.fr>
4679 * tests/generate.awk: Tag the tests with `documentation'.
4680 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
4681 Use the make the existing modtest tests more uniform, and complete
4682 the set of possibilities.
4684 2001-10-01 Akim Demaille <akim@epita.fr>
4686 * config/gmp.m4: Consult the user before using GMP: use
4688 * configure.ac: Adjust.
4689 * modules/gmp.c: No protection needed as the module is not built
4692 2001-10-01 Akim Demaille <akim@epita.fr>
4694 * tests/generate.awk: Remove debugging code.
4695 (fatal): Specify the current location.

4700 2001-10-01 Akim Demaille <akim@epita.fr>
4702 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
4703 (m4_regexp_compile): New.
4704 (regexp, patsubst): Use it.
4706 2001-09-30 Gary V. Vaughan <gary@gnu.org>
4708 Reinstate the memory handling improvements from the patch I just
4709 reverted. Relevant ChangeLog entries repeated here:
4711 * m4/module.c (m4_module_remove): New function that holds the core
4712 of the old m4_module_unload.
4713 (m4_module_unload): Use it.
4714 (m4_module_unload_all): When we know the modules will never be
4715 used again (i.e. on exit), free up as much module memory as
4716 possible. There are still some artifacts from resident modules
4717 living inside ltdl.c, but everything else is freed.
4718 * m4/debug.c (m4_debug_exit): Free memory allocated in
4720 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
4721 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
4722 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
4723 * m4/m4module.h: Updated prototypes.
4724 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
4725 * m4/hash.h: Updated prototypes.
4726 * src/main.c (main): Use all these new functions to clean up as
4727 much memory as possible before exit.
4729 2001-09-30 Gary V. Vaughan <gary@gnu.org>
4731 Reverted my large patch for removing the old m4_symbol
4732 structure on 2001-09-20. We are still not happy about the way
4733 trace works in conjunction with defn and undefine, and leaving
4734 the reverted patch active prevents us from moving the traced
4735 bit from the definition back to the symbol.
4737 2001-09-30 Gary V. Vaughan <gary@gnu.org>
4739 * configure.in: Moved to...
4740 * configure.ac: ...here. Added a libtool like timestamped
4741 banner, and tidied up the libltdl cruft.
4742 * config/mkstamp: Script to extract a timestamp from ChangeLog.
4743 * modules/Makefile.am (INCLTDL): Removed. This is required
4744 only when libltdl is configured in a subdirectory.
4745 * src/Makefile.am: Ditto.
4746 (LIBADD_DL): No need to add this again, libtool already knows
4747 that libm4.la depends on it.
4748 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
4751 * TODO: stackovf.c is basically broken.
4752 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
4754 2001-09-28 Akim Demaille <akim@epita.fr>
4756 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
4758 2001-09-27 Akim Demaille <akim@epita.fr>
4760 * tests/m4.in: Don't use short options.
4761 Simplify the stderr signature normalization.
4763 2001-09-27 Akim Demaille <akim@epita.fr>
4765 tests/m4 shall be position independent.
4769 * tests/testsuite.at: No args to AT_INIT.
4770 * configure.in, tests/Makefile.am: Adjust.
4772 2001-09-22 Akim Demaille <akim@epita.fr>
4774 Autotest has changed again.
4776 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
4777 (package.m4): Remove.
4778 * configure.in: Adjust to LIBADD_GMP.
4780 2001-09-21 Gary V. Vaughan <gary@gnu.org>
4782 * config/gmp.m4 (AC_ARG_WITH): Removed.
4783 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
4784 (AC_LIB_GMP): When performing a test compile against libgmp,
4785 include the header gmp.h if possible, and link against -lgmp. If
4786 they both work define USE_GMP.
4787 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
4788 (mpeval_LTX_init_func): Complain on load that there was no libgmp
4791 2001-09-20 Gary V. Vaughan <gary@gnu.org>
4793 * m4/evalparse.c: Moved to...
4794 * modules/evalparse.c: ...here. This code is shared between
4795 modules/mpeval.c and modules/m4.c, so there is no need to pollute
4796 the libm4 API with its details. Moderately rewritten to interface
4797 into its clients more simply.
4798 * m4/eval.c: Deleted. Migrated functionality to...
4799 * modules/m4.c: ...here.
4800 (builtin_eval): Implemented in terms of the new interface style.
4801 * modules/mpeval.c (builtin_mpeval): Ditto.
4802 * m4/m4module.h: Removed references to the former m4/eval.c.
4803 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
4804 (EXTRA_libm4_la_SOURCES): Deleted.
4805 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
4806 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
4808 2001-09-20 Akim Demaille <akim@epita.fr>
4810 * config/gmp.m4 (AM_WITH_GMP): Rename as...
4812 By default, use gmp.
4814 * configure.in: Adjust.
4815 Use Automake conditionals for USE_GMP.
4816 Always compute sizeof (long long int).
4817 This was a bug BTW, as `eval' (not `mpeval') depends on it:
4818 before, it was used _only_ if mpeval was not activated.
4819 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
4820 (mpeval_la_LIBADD): New macros.
4821 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
4823 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
4824 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
4827 2001-09-20 Akim Demaille <akim@epita.fr>
4829 * tests/Makefile.am (package.m4): New.
4830 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
4832 2001-09-20 Gary V. Vaughan <gary@gnu.org>
4834 More cleanup. After the last patch, m4_symbol holds nothing but
4835 the head of a chain of m4_token_data. So I have removed the old
4836 m4_symbol, so that m4_token_data chains are stored directly in the
4837 value cell of a hash table node. But there's more... m4_symbol
4838 was a more natural name for the symbol value cell, and now that it
4839 is gone I have renamed the former m4_token_data structure to
4840 m4_symbol. This change turned out to be a pig to get right, since
4841 the original code didn't need to modify the value cell itself,
4842 since changing the chain happened inside the m4_symbol that used
4843 to be returned -- I had to pass the address of the value cell
4844 across various function calls, incase the head value changed. I
4845 also tightened up the memory management to help me find a nasty
4846 memory corruption bug that took me all night to track down...
4848 * m4/m4private.h (struct m4_symbol): Removed.
4849 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
4851 * m4/hash.c (m4_hash_iterator_value): Return the address of the
4852 value cell. Updated all callers.
4853 * m4/symtab.c: Took advantage of the simplification in the data
4854 structures to rewrite a lot of this file more simply. There is
4855 still some room for optimisation here, but we should tackle that
4856 systematically closer to the release.
4858 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
4859 revealed. This version is ahead of CVS libtool until I get chance
4860 to flush my changes.
4861 * m4/module.c (m4_module_remove): New function that holds the core
4862 of the old m4_module_unload.
4863 (m4_module_unload): Use it.
4864 (m4_module_unload_all): When we know the modules will never be
4865 used again (i.e. on exit), free up as much module memory as
4866 possible. There are still some artifacts from resident modules
4867 living inside ltdl.c, but everything else is freed.
4868 * m4/debug.c (m4_debug_exit): Free memory allocated in
4870 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
4871 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
4872 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
4873 * m4/m4module.h: Updated prototypes.
4874 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
4875 * m4/hash.h: Updated prototypes.
4876 * src/main.c (main): Use all these new functions to clean up as
4877 much memory as possible before exit.
4879 2001-09-18 Gary V. Vaughan <gary@gnu.org>
4881 The `traced' flag needs to be attached to the definition of a
4882 symbol rather than the current symbol containing the definition.
4883 Implementing this showed up some long standing post 1.4 bugs in
4884 flag propogation which I also fixed.
4886 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
4887 (struct m4_token_data): And add it back in here.
4888 * m4/input.c (init_macro_token): Propogate the traced flag
4890 * m4/macro.c (expand_argument): Ditto.
4891 * tests/builtins.at (trace2, trace3): New tests based on Akim's
4894 2001-09-08 Gary V. Vaughan <gary@gnu.org>
4896 * m4/m4private.h (struct m4_token_data): Simplified by removing
4897 the redundant `traced' flag, and one level of structure nesting.
4898 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
4899 * m4/input.c (init_macro_token): No need to initialise removed
4901 * m4/macro.c (expand_argument): No need to copy it either.
4902 * m4/utility.c (m4_token_data_func_traced): Or provide an access
4905 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
4906 dependant on multiple symbols with the same key, so preserving
4907 relative symbol order in each bucket during resizing is no longer
4908 required. The resize function is considerably faster as a result.
4910 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
4911 s/m4_symbol_insert/m4_symbol_define/g;
4912 s/m4_builtin_insert/m4_builtin_define/g;
4913 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
4915 2001-09-08 Gary V. Vaughan <gary@gnu.org>
4917 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
4918 commits, the m4_lookup_symbol dispatch function is split into
4919 specialised functions that must be called directly.
4921 * m4/m4module.h (m4_symbol_lookup_t): Removed.
4922 * m4/symtab.c (m4_lookup_symbol): Removed.
4923 (m4_symbol_builtin, m4_symbol_macro): New functions.
4924 * m4/builtin.c (m4_builtin_define): Split into...
4925 (m4_builtin_pushdef, m4_builtin_insert): ...these.
4926 (m4_macro_define): Split into...
4927 (m4_macro_pushdef, m4_macro_insert): ...these.
4928 * src/main.c (main): Set command line macros from `-D' parameters
4929 using `m4_macro_define'.
4931 2001-09-08 Gary V. Vaughan <gary@gnu.org>
4933 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
4934 this from m4_remove_table_reference_symbols().
4935 * m4/m4module.h, m4/module.c: Updated all references.
4937 2001-09-07 Akim Demaille <akim@epita.fr>
4939 * modules/stdlib.c, modules/times.c: Misc cleanups.
4941 2001-09-07 Akim Demaille <akim@epita.fr>
4943 * configure.in: We now need Autoconf 2.52e.
4944 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
4945 and `M4_SYMBOL_DELETE'.
4946 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
4947 * src/main.c (main): Adjust.
4949 2001-09-06 Gary V. Vaughan <gary@gnu.org>
4951 Fix the obstack.h problem once and for all! At configure time we
4952 can test for a system supplied obstack.h: depending on the
4953 result, we now generate system.h with an #include of the correct
4954 header. As a bonus, I've also added a --with-included-obstack,
4955 incase the user doesn't like the system obstack for some
4956 reason... and also we can test the shipped obstack on a system
4957 that has oe of its own. We also now need to be careful to add
4958 build directories to the include search path, since the generated
4959 system.h will be in the build tree.
4961 * configure.in (AC_CONFIG_FILES): Generate system.h from
4963 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
4964 include the system obstack header or the copy shipped with M4.
4965 Allow the user to override configure and force the build to use
4966 the shipped version.
4967 * m4/system-h.in: New file, template for...
4968 * m4/system.h: ...this. Now deleted.
4969 * m4/m4module.h: Include system.h before everything else.
4970 * src/freeze.c: Ditto.
4971 * m4/Makefile.am (dist-hook): Remove generated system.h.
4972 (INCLUDES): Check builddir for generated headers before checking
4974 * modules/Makefile.am (INCLUDES): Ditto.
4975 * src/Makefile.am (INCLUDES): Ditto.
4977 2001-09-05 Gary V. Vaughan <gary@gnu.org>
4979 * TODO: Remove the items that have been addressed already.
4981 2001-09-05 Akim Demaille <akim@epita.fr>
4983 * src/main.c (main): Standardize --version.
4985 2001-09-05 Akim Demaille <akim@epita.fr>
4987 * modules/format.c (format): Have a bigger `str'.
4989 2001-09-05 Akim Demaille <akim@epita.fr>
4991 Rationalize warnings, reporting the macro name as if it were a
4992 program name, and assertions.
4994 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
4996 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
4998 Use assert for internal errors.
4999 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
5001 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
5003 * tests/builtins.at (pushpop): Adjust.
5005 2001-09-05 Akim Demaille <akim@epita.fr>
5007 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
5010 2001-09-05 Akim Demaille <akim@epita.fr>
5012 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
5013 * m4/macro.c, m4/symtab.c: Adjust.
5015 2001-09-05 Akim Demaille <akim@epita.fr>
5017 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
5018 (m4_symbol_pop, m4_symbol_del): this.
5019 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
5020 (m4_symbol_popdef, m4_symbol_delete): New.
5021 (m4_lookup_symbol): Adjust.
5022 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
5024 2001-09-05 Akim Demaille <akim@epita.fr>
5026 * m4/m4module.h (m4_symbol_lookup): Rename as...
5027 (m4_symbol_lookup_t): this.
5029 2001-09-05 Akim Demaille <akim@epita.fr>
5031 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
5033 * m4/symtab.c (m4_lookup_symbol): Adjust.
5035 2001-09-03 Gary V. Vaughan <gary@gnu.org>
5037 Bootstrap will now work with Libtool 1.4.1 or higher:
5038 * bootstrap: Remove stale autom4te.cache files when
5040 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
5042 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
5043 libtool.m4 directly.
5044 Run libtoolize to refresh ltmain.sh.
5045 * config/ltmain.sh: Deleted.
5046 * acinclude.m4: Deleted.
5047 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
5049 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
5050 implementation for the cvs impaired libtool user.
5052 2001-09-03 Akim Demaille <akim@epita.fr>
5054 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
5056 Avoid using `default' in switch, as it hides useful compiler
5057 warnings when a case is forgotten.
5059 2001-09-03 Akim Demaille <akim@epita.fr>
5061 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
5062 is no such thing as `WITH_MODULES'.
5064 2001-09-03 Akim Demaille <akim@epita.fr>
5066 Improve the test suite's selfcontainedness.
5068 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
5069 (Include, Undivert): Tag the other input files.
5070 * tests/generate.awk: Catch `@comment file:'.
5071 `-I $src' is no longer needed.
5072 `next' is really like `return': the rest is skipped.
5073 Adjust to `input.m4'.
5074 (fatal): New function.
5075 * tests/foo, tests/incl.m4: Remove.
5077 2001-09-01 Gary V. Vaughan <gary@gnu.org>
5079 The shadowing mechanism and, infact, the whole symbol table
5080 implementation was creaking under the weight of the features piled
5081 on top of it. We now have a separate hash table module which will
5082 dynamically resize to keep symbol density withing good performace
5083 limits, and a new symtab module layered above it. Symbol lookups
5084 are now marginally more efficient (since the shadowed flag is no
5085 longer required) and symbol removal, such as on module unload, is
5086 considerably faster due to a reorganisation of the data structures
5089 * src/main.c (main): Don't mention `-H'.
5090 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
5093 * m4/hash.c: New generalised dynamic hash table data structure
5095 * m4/hash.h: Public interface.
5096 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
5097 (libm4_la_SOURCES): Add hash.c.
5098 * m4/symtab.c: More or less rewritten from scratch, within the
5099 bounds of the previous API.
5100 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
5101 call. Updated all callers.
5102 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
5103 declarations to reflect API changes.
5104 (M4INIT): Generate a declaration too, to avoid the warning with
5105 --enable-debug builds.
5108 * m4/utility.c (hash_table_size): Removed.
5109 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
5110 names, which are then looked up by builtin_dumpdef() as necessary.
5111 This implies a small speedup in builtin_symbols(), which discarded
5112 all of the symbol info under the old call.
5113 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
5114 shadowing is implicit in respect to the new data structures.
5115 symbol names are no longer duplicated here, they are stored in the
5116 key field of the hash table.
5117 Moved macro_args and blind_no_args...
5118 (m4_token_data): ...to here.
5119 m4/macro.c (expand_macro): Added a name argument since the symbol
5120 name is no longer copied into each struct m4_symbol. Modified all
5122 (collect_arguments): Ditto.
5123 * modules/m4.c (set_trace): Ditto.
5124 * modules/gnu.c (builtin_symbols): Updated.
5125 * src/freeze.c (produce_symbol_dump): Much improved in light of
5126 the improved symbol table layout.
5128 2001-09-01 Gary V. Vaughan <gary@gnu.org>
5130 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
5132 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
5133 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
5134 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
5135 SYMBOL_HANDLE): Ditto.
5136 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
5137 modules/gnu.c, modules/m4.c, src/freeze.c,
5138 src/main.c: Updated all references.
5140 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
5141 Automake 1.5 chokes on dynamic source file lists, Besides, it is
5142 already listed in m4_LDADD... how did that ever used to work?
5143 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
5145 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
5146 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
5148 * tests/m4: Don't call the m4 wrapper script with libtool, it
5149 works fine all by itself.
5151 2001-08-30 Gary V. Vaughan <gary@gnu.org>
5153 The experimental `changeword' feature never took off, and has
5154 no obvious advantages over `changesyntax' to compensate the
5155 enormous speed penalty it carries:
5156 * configure.in (ENABLE_CHANGEWORD): Removed.
5157 * m4/m4module.h (m4_set_word_regexp): Removed.
5158 * m4/m4private.h (m4_token_data): Removed original_text field.
5159 * m4/utility.c (m4_token_data_orig_text): Removed.
5160 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
5161 * m4/macro.c: Ditto.
5162 * src/main.c: Ditto.
5163 * modules/Makefile.am (changeword.la): Removed.
5164 * modules/changeword.c: File removed.
5165 * doc/m4.texinfo: References to changeword and --word-regexp
5167 * po/POTFILES.in: modules/changeword.c removed.
5168 * tests/atlocal.in (ENABLE_CHANGEWORD): Removed.
5169 * tests/builtins.at (changeword): Test removed.
5171 2001-08-30 Akim Demaille <akim@epita.fr>
5173 * bootstrap.sh: Create aclocal.m4 instead of modifying it.

5176 * config/Makefile.am (STANDARD_MACROS): Rename as...
5177 (ACLOCAL_MACROS): this.
5178 (list-standard-macros): Remove.
5181 2001-08-29 Gary V. Vaughan <gary@gnu.org>
5183 In an attempt to moderate my egomania...
5184 * tests/modules.at: Remove attributions.
5186 * tests/generate.awk: When making substitutions to "@&t@", either
5187 "&" or "\&" in the substitution string argument to gsub refer back
5188 to the matched text. "@\\&t@" seems to work though, Tests 43 and
5191 2001-08-29 Akim Demaille <akim@epita.fr>
5193 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)
5194 (include, indir, multiquotes, patsubst, pushdef/popdef, regexp)
5195 (sync-lines, trace, translit, undivert, wrap): Move to...
5196 * tests/builtins.at: this new file.
5197 * tests/others.at (Discard comments, import-environment): Move to...
5198 * tests/options.at: this new file.
5200 2001-08-29 Akim Demaille <akim@epita.fr>
5202 * tests/others.at (Freezing modules)
5203 (--module-directory: absolute path, modpath2, modpath3)
5204 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
5205 * tests/modules.at: here, new file.
5206 * tests/others.at, tests/generate.awk: Add a banner.
5207 * tests/testsuite.at: Adjust.
5208 (AT_CHECK_M4_FILTER): New, but unused.
5210 2001-08-29 Akim Demaille <akim@epita.fr>
5212 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
5214 * tests/others.at (wrap): Inline wrap.m4.
5215 (shadow): Inline shadow.m4.
5216 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
5217 * tests/m4: Simplify.
5219 2001-08-29 Akim Demaille <akim@epita.fr>
5221 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
5224 2001-08-29 Akim Demaille <akim@epita.fr>
5226 * tests/generate.awk (normalize): s/@__@/@&t@/.
5228 2001-08-28 Akim Demaille <akim@epita.fr>
5230 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.
5232 2001-08-28 Gary V. Vaughan <gary@gnu.org>
5234 * bootstrap (generate.awk): Generate test cases with new script.
5236 2001-08-27 Akim Demaille <akim@epita.fr>
5238 * tests/Makefile.am (installcheck-local): Don't use
5239 `dc_install_base' which is not visible here, but `exec_prefix'
5240 which is clearly the RT anyway.
5241 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
5242 related to testing a now installed m4.
5243 * tests/m4: Do it here.
5245 2001-08-27 Akim Demaille <akim@epita.fr>
5247 * tests/others.at (indir): Formatting change.
5249 2001-08-27 Akim Demaille <akim@epita.fr>
5251 * tests/Makefile.am (installcheck-local): New.
5252 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
5254 Prefer options over envvars.
5255 * src/main.c (main): First bug caught by the test suite (yeah!):
5256 --batch lacked a `break' which resulted in an accidental
5257 invocation of --discard-comments.
5259 2001-08-27 Akim Demaille <akim@epita.fr>
5261 * tests/others.at (capitalize, changeword, comments, ddivert)
5262 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
5263 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
5264 (sysv-args, trace, translit, undivert): Don't rely on files in
5265 examples/: AT_DATA them.
5267 2001-08-27 Akim Demaille <akim@epita.fr>
5269 Let the test suite use a wrapper around the not installed m4 to
5270 pretend it is (installed).
5272 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
5273 such a way that m4 does not process them.
5274 * configure.in: The package name seems to be `m4', not `M4'.
5276 * tests/atlocal.in (at_package, M4): Remove.
5277 * tests/testsuite.at, tests/others.at: Use m4, not $M4.
5279 2001-08-27 Akim Demaille <akim@epita.fr>
5281 * tests/Makefile.am (CLEANFILES): Remove.
5282 (DISTCLEANFILES, clean-local): New.

5285 2001-08-27 Akim Demaille <akim@epita.fr>
5287 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
5288 Don't use aclocal: it's written by hand.
5289 * aclocal.m4: m4_include all the files instead of being built by
5291 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
5292 until it reads the traces by itself.
5293 * configure.in: Require Autoconf 2.42c as we are now using
5294 AC_CONFIG_TESTDIR instead of AT_CONFIG.
5295 Catch unexpanded `jm_' macros.
5296 * config/atconfig.m4: Remove.
5297 * config/error.m4: new.
5298 * config/Makefile.am: Ship the files included by aclocal.m4.
5299 * tests/Makefile.am (TESTSUITE_SOURCES): Rename as...
5300 (TESTSUITE_AT): this, to please Automake.
5301 (TESTSUITE): This target uses autotest/autotest.m4, not
5302 autotest/general.m4.
5303 * tests/testsuite.at: Prereq Autotest 2.52c.
5304 * examples/Makefile.am (pkgdata_DATA): Rename as...

5307 (dist_man_mans): this.
5309 2001-08-20 Gary V. Vaughan <gary@gnu.org>
5311 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
5312 Robert Collins, building on Cygwin no longer requires Windows
5313 import and export symbol decorations.
5314 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.
5315 * m4/error.h (M4_SCOPE) [cygwin*]: Ditto.

5328 2001-08-20 Gary V. Vaughan <gary@gnu.org>
5330 Ansify the source. Previously we had a mix, where my code was
5331 in a K&R compatible style, and the preexisting code was in ANSI
5332 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
5333 and now the code base is much cleaner.
5335 * m4/system.h: Remove M4_PARAMS macro and all users. Remove
5336 VOID macro and all users.
5337 * m4/m4module.h: Ansify function prototypes and headers.

5355 2001-08-20 Akim Demaille <akim@epita.fr>
5357 * config/atconfig.m4: s/EOF/ATEOF/, so that configure can be
5358 generated with stock 2.52.
5360 2001-08-20 Akim Demaille <akim@epita.fr>
5362 * config/atconfig.m4: New, until part of Autoconf per se.
5363 * configure.in (AT_CONFIG): Use it.
5365 * tests/mkconfig.sh, tests/atconfig.in, tests/defs: Remove.
5366 * tests/atlocal.in: New.
5367 * tests/generate.awk: For the time being, the empty quadrigraph is
5369 * tests/others.at (changeword, gmp): Check the configuration
5370 variable against `yes'.
5371 * tests/testsuite.at (dnl): Allow it, as it's used all over the
5374 2001-08-20 Akim Demaille <akim@epita.fr>
5376 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
5377 * modules/m4.c (undivert): Disable the possibility of undiverting
5378 several files at once: it is not documented, it is inconsistent
5379 with the other macros, it can be straightforwardly mocked by
5380 several invocations, and most importantly, it prevents the
5381 possibility of other kinds of extension.
5382 Use `m4_numeric_arg'.
5384 2001-08-20 Akim Demaille <akim@epita.fr>
5386 * examples/include.m4: Typo.
5387 * tests/generate.awk: Really add it.
5388 * tests/Makefile.am: Adjust.
5389 * tests/others.at (Discard comments): It sure fails without `-c'.
5390 (include, undivert): Add -I examples/.
5392 2001-08-20 Akim Demaille <akim@epita.fr>
5394 Use sprintf, not ecft and friends since it is standard, portable,
5395 simplifies the code, and since the latter is even deprecated
5396 according to the GNU libc documentation.
5398 * modules/format.c: Drop evct support.
5400 2001-08-19 Gary V. Vaughan <gary@gnu.org>
5402 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Cleaned up. Don't test
5404 * configure.in: ...do it here instead.

5440 files in error messages.
5442 2001-08-17 Akim Demaille <akim@epita.fr>

5445 * tests/others.at: Adjust input files paths.
5446 * tests/atconfig.in: Set top_builddir.

5448 `testsuite' is in src, not build.
5450 2001-08-17 Akim Demaille <akim@epita.fr>
5452 * tests/Makefile.am (EXTRA_DIST): Ship generate.awk.
5453 (generate.at): Install a temporary hack until the actual
5454 generate.awk is added to the repository.
5455 * tests/atconfig.in: New.
5457 2001-08-17 Akim Demaille <akim@epita.fr>
5459 Really apply the patch ``Drop Autoconf 2.13 compatibility.''
5461 2001-08-17 Akim Demaille <akim@epita.fr>
5463 * doc/m4.texinfo: Promote proper quotation.

5509 (unload.test): Keep their authorship.
5510 (discard-comments, gmp, import-environment, modfreeze)

5527 Start using Autotest. atconfig creation is still lacking.
5529 * examples/patsubst.m4, modules/modtest.m4, modules/shadow.m4,
5530 * examples/reverse.m4, tests/other-tests/import-environment.m4,
5531 * tests/other-tests/iso8859.m4: Don't produce trailing blanks.
5532 * tests/other-tests/import-environment.test: Don't check LANGUAGE
5533 as it might be `unset', or set to `C'.
5534 * tests/other-tests/iso8859.test, tests/other-tests/modpath1.test,
5535 * tests/other-tests/modpath2.test, tests/other-tests/modpath3.test,
5536 * tests/other-tests/modpath4.test, tests/other-tests/modtest.test,
5537 * tests/other-tests/patsubst.test, tests/other-tests/reverse.test,
5538 * tests/other-tests/shadow.test: Adjust.
5539 * tests/testsuite.at, tests/others.at: New.
5540 * tests/Makefile.am: Adjust.
5542 2001-08-17 Akim Demaille <akim@epita.fr>
5544 Drop Autoconf 2.13 compatibility.
5546 * configure.in (changeword): No need to undefine it, as anyway if
5547 it's defined, M4sugar moved it as m4_changeword.
5548 And anyway, proper quotation is enough.
5549 (m4_pattern_allow): As it exists in 2.50, just use it.
5550 (AC_OUTPUT): Split in AC_CONFIG_FILES and AC_CONFIG_COMMANDS.
5551 Don't handle Gettext's duties, let it handle them.
5552 * config/gnu-obstack.m4: Use m4_pattern_allow directly.
5554 2001-08-17 Akim Demaille <akim@epita.fr>
5556 * modules/m4.c (m4_dumpdef): Output to stderr, not m4_debug.
5557 (m4_errprint): Use fputs.
5558 * doc/m4.texinfo (Invoking m4) <--error-output>: errprint and
5559 dumpdef are not concerned.
5560 (Dumpdef, Errprint): Emphasize their insensitivity to
5562 * doc/Makefile.am: Add `TAGS' support.
5563 (MAINTAINERCLEANFILES): Remove texinfo.tex and mdate-sh which are
5565 * config/Makefile.am (MAINTAINERCLEANFILES): New.
5567 2001-08-17 Akim Demaille <akim@epita.fr>
5569 * modules/Makefile.am (ETAGS_ARGS): New.
5571 2001-08-17 Akim Demaille <akim@epita.fr>
5573 * m4/symtab.c (m4_hack_all_symbols, m4_lookup_symbol): Formatting
5576 2001-08-17 Akim Demaille <akim@epita.fr>
5578 * m4/builtin.c (m4_macro_define): Do not reset SYMBOL_TRACED.
5580 2001-08-17 Akim Demaille <akim@epita.fr>
5582 * m4/m4module.h (m4/list.h): Don't include it.
5584 2001-08-16 Gary V. Vaughan <gary@gnu.org>
5586 m4_modules are no more, we use lt_dlhandles directly and let
5587 latest libltdl features manage the list of loaded modules.
5588 * acinclude.m4: Regenerated.
5589 * m4/ltdl.c: Updated from master copy.
5590 * m4/module.c: Reimplemented to take advantage of advances in
5592 * m4/builtin.c (m4_builtin_find_by_name): Traverse loaded module
5593 list with lt_dlhandle_next.
5594 (m4_builtin_find_by_func): Ditto.
5595 (m4_builtin_table_install): Use lt_dlhandle.
5596 (m4_macro_define): Ditto.
5597 (m4_macro_table_install): Ditto.
5598 m4/module.h: Prototype new module management API.
5599 (m4_modules): No longer required.
5600 (m4_module_init_t, m4_module_finish_t): POSIX namespace
5601 violations, renamed to...
5602 (m4_module_init_func, m4_module_finish_func): ...these,
5604 (M4INIT_HANDLER): Clean way to declare init functions in modules.
5605 (M4FINISH_HANDLER): And similarly for finish functions.
5606 * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER
5607 -- Add indirection to the CONC macro so that arguments are
5609 * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
5610 * modules/shadow.c (m4_init_module): Ditto.
5611 Due to new init function semantics, be careful to perform the
5612 initialisation only on first load.
5613 * modules/perl.c (m4_init_module): Ditto. And Ditto.
5614 (m4_finish_module): Replaced with M4FINISH_HANDLER.
5615 Due to new finish function semantics, be careful to perform the
5616 finalisation only on first load.
5617 * m4/m4private.h (m4_module): Removed in favour of...
5618 (m4_module_data): ...structure without all the wrapper fields.
5619 Instances of this new structure are stored associated lt_dlhandles
5620 with lt_dlcaller_data_set().
5621 * m4/builtin.c (m4_builtin_define): Takes a handle argument
5622 instead of the old module argument.
5623 (m4_builtin_table_install): Ditto.
5624 * modules/load.c (m4_resident_module): Removed. This is no
5625 longer implemented as a magic symbol...
5626 * modules/m4.c (m4_resident_module): Ditto.
5627 * modules/load.c (M4INIT_HANDLER): ...the module init function now
5628 uses the ltdl api to make the module resident.
5629 * modules/m4.c (M4INIT_HANDLER): Ditto.
5630 * modules/load.c (builtin_modules): Traverse the loaded module
5631 list with lt_dlhandle_next.
5632 (builtin_load): Much simplified in light of the reimplemented
5634 * src/freeze.c (produce_module_dump): Cleaned up and optimised in
5635 light of the m4/module.c rewrite.
5636 (produce_symbol_dump): Ditto.
5637 (reload_frozen_state): Ditto.
5638 * m4/list.c, m4/list.h: Files deleted. No longer required.
5639 * m4/Makefile.am (pkginc_HEADERS): Delete list.h reference.
5640 (libm4_la_SOURCES): Delete list.c reference.
5641 * m4/m4private.h (m4_token_data): Add a handle field. This
5642 eliminates many of the searches to find the handle associated with
5643 various tokens that are passed between functions.
5644 (struct m4_symbol): Removed the module field. The
5645 module association does not belong with the symbol...
5646 * m4/input.c (struct m4_builtin): ...it belongs with the builtin
5647 that the module implementation code is from. Added a handle
5649 (m4_push_macro): Add a `handle' argument. Changed all callers.
5650 (init_macro_token): Set the `handle' field for the
5652 * m4/macro.c (expand_argument): Copy the new handle field during
5654 * modules/m4.c (macro_install): Use the new handle field to
5655 optimise the search for the correct builtin structure, and pass
5656 the handle details to m4_builtin_define.
5658 2001-08-15 Akim Demaille <akim@epita.fr>
5660 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Be sure `m4/' exists
5661 when creating `m4/obstack.h'.
5662 * tests/Makefile.am (TESTS_ENVIRONMENT): Pass top_srcdir and
5664 * tests/defs: Make them absolute.
5665 (CDPATH) Neutralize.
5666 * tests/gethem: Use them.
5668 2001-08-14 Gary V. Vaughan <gary@gnu.org>
5670 * config/ltmain.sh: Doh! Import again for a quoting fix that
5671 prevented any regression test from passing.
5673 * m4/m4module.h (obstack.h): Choose between installed version
5674 and shipped version based on configure tests.
5675 * src/freeze.c (obstack.h): Ditto.
5677 * acconfig.h: Removed. No longer required.
5679 * bootstrap: Rewritten to play nicely with Autoconf 2.5x.
5680 * configure.in (MY_NAME, MY_VERSION): Define these once, and feed
5681 them to AC_INIT and AM_INIT_AUTOMAKE.
5682 * Makefile.am (AUTOMAKE_OPTIONS): Remove `gnits' which would
5683 disallow MY_NAME and MY_VERSION arguments to AM_INIT_AUTOMAKE.
5684 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Don't choke on
5685 shell variable m4_cv_func_obstack_h.
5686 * tests/defs (M4): Be more careful about relative path to libtool
5687 script and m4 binary by using $srcdir.
5689 * src/main.c (main): Use lt_dlinsertsearchdir to prepend -M
5690 optargs to the existing libltdl search path.
5691 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.
5692 * m4/ltdl.c: Updated.
5694 * config/ltmain.sh: Ditto.
5696 2001-08-11 Gary V. Vaughan <gary@gnu.org>
5698 * src/main.c (main): Add `-b' (for `batch') mode switch to force
5699 interactive mode off.
5701 2001-08-10 Akim Demaille <akim@epita.fr>
5703 * configure.in: Require Autoconf 2.52.
5704 (AC_ARG_PROGRAM): Remove, handled by Automake.
5705 (m4_getopt): Rename as...
5706 (m4_getopt_h): this.
5707 Allow the tokens `m4_cv_*', `m4_top_srcdir', and `m4_getopt_h'.
5708 Undefine `changeword' only if defined.
5709 * config/gnu-obstack.m4: Require Autoconf 2.52.
5710 (M4_AC_FUNC_OBSTACK): Rename `m4_obstack' and `m4_obstack_h'.
5713 2001-08-09 Yuji Minejima <ggb01164@nifty.ne.jp>
5715 * doc/m4.texinfo: Fix some typos, and apply some small
5718 2001-08-09 Andreas Schwab <schwab@suse.de>
5720 * src/main.c (main): Fix improper uses of error (missing format
5723 2001-08-07 Akim Demaille <akim@epita.fr>
5725 Improve `make distcheck'.
5727 * configure.in: Be sure to be able to run `mkconfig.sh' when src
5729 * Makefile.am (dist-hook): Remove, as it is no longer needed.
5730 * doc/m4.texinfo (Include): Add missing blank.
5731 * m4/Makefile.am (EXTRA_DIST): Distribute gnu-obstack.h and
5734 2001-08-07 Akim Demaille <akim@epita.fr>
5736 * m4/evalparse.c: A better introductory comment.
5737 * m4/m4module.h (M4_DEBUG_PRINT2): s/M4_debug/m4_debug/.
5738 * m4/macro.c: Adjust old comments.
5739 * modules/README: Typo.
5741 2001-08-07 Akim Demaille <akim@epita.fr>
5743 * config/gnu-obstack.m4: New.
5745 2001-08-07 Akim Demaille <akim@epita.fr>
5747 * config/Makefile.am, config/stackovf.m4: New.
5748 * configure.in, Makefile.am: Adjust.
5750 2001-08-05 gettextize <bug-gnu-utils@gnu.org>
5752 * po/Makefile.in.in: Upgrade to gettext-0.10.39.
5753 * po/cat-id-tbl.c: Remove file.
5754 * po/stamp-cat-id: Remove file.
5756 2001-04-08 Roderick Koehle <Roderick.Koehle@infineon.com>
5758 * modules/format.c (format): Formatting for %f was not
5759 interpreting the position of the decimal point correctly for
5762 2000-12-01 Gary V. Vaughan <gary@gnu.org>
5764 * TODO: Removed m4exit bug.
5765 * modules/load.c (m4_resident_module): Make this module resident.
5766 * module/m4.c (m4_resident_module): Ditto.
5767 * m4/modules.c (m4_module_load): Use new ltdl resident modules
5768 feature to mark modules as resident if they export
5769 `m4_resident_module' as TRUE.
5770 (m4_module_unload): Do not remove resident modules, and take care
5771 with symbol insertion and deletion with resident modules.
5772 * m4/ltdl.c, m4/ltdl.h: Update to latest unreleased versions to
5773 use resident modules feature.
5775 2000-11-30 Gary V. Vaughan <gary@gnu.org>
5777 * TODO: Updated. Removed some cruft that has since been fixed
5778 or implemented. Added some more entries.
5781 * modules/README: Updated.
5782 * doc/m4.texinfo: Updated.
5784 * modules/gnu.c (builtin_functions): Make indir orthogonal to
5785 builtin, in that each is recognised as a macro only with parameters
5786 (builtin_indir): Passing 0 arguments is now an error, as with
5789 * src/main.c (usage): Added missing description of `-c' option.
5791 2000-11-29 Gary V. Vaughan <gary@gnu.org>
5793 Consolidate the myriad of dispersed test scripts into the
5794 tests subdirectory. I think I now have all the file where I
5795 want them, so there shouldn't be anymore upheaval =)O|
5797 * tests/Makefile.am: Updated to run the new tests added below.

5834 modules/unfrozen.m4, modules/unload.test: Removed.
5836 Move the implementation of GMP support for the mpeval() builtin
5837 into a loadable module that depends on libgmp. mpeval() and
5838 eval() share a common parser, now in m4/evalparser.c; the code
5839 in m4/numb.c and m4/numb.h is now physically split between
5840 m4/eval.c (the eval() backend) and modules/mpeval.c (the
5841 mpeval() backend), rather than being differentiated by cpp
5842 macros and multiple inclusion. The mpeval module is always
5843 built but will generate an diagnostic if it is used from an
5844 installation that didn't link in the gmp library.
5845 * modules/Makefile.am: build and install the new mpeval module.
5846 * modules/mpeval.c: Now contains the former parts of m4/numb.c
5847 and m4/numb.h that are required for gmp support in mpeval().
5848 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
5849 * m4/evalmp.c: Removed.
5850 * m4/m4module.h: Removed conditional prototype for
5852 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
5853 and m4/numb.h that do not rely on gmp.
5854 * m4/evalparse.c: New file, contains the shared parts of the
5855 eval() and evalmp() parser implementations, and is no longer
5856 unencumbered by cpp magic to uncover the right parts.
5857 * m4/numb.h: Removed. It's former contents are split between
5858 m4/eval.c and modules/mpeval.c.
5861 * tests/other-tests/changeword.test: New test. Rudimentary
5862 testing of changeword builtin runs only if --wnable-changeword
5863 was used at configure time.
5864 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
5865 alternation correctly. Split into two expressions to compensate.
5866 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
5867 * modules/Makefile.am: Build changeword module.
5868 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
5869 only when --enable-changeword was passed to configure.
5870 (builtin_changeword): If --enable-changeword was not used, then
5871 report that changeword() builtin has no support in m4 binary.
5873 2000-11-28 Gary V. Vaughan <gary@gnu.org>
5875 * src/main.c (main): Fixed a particularly nasty bug is
5876 user_search_path setting -- the -M flag processing must be
5877 extremely careful with search path ordering, or else the default
5878 installed module directory (possibly containing modules from a
5879 previous release) is placed earlier in the search path than any -M
5880 arguments (which are relied upon to load uninstalled modules with
5881 most of the tests in the regresion suite).
5883 * modules/load.c (builtin_load): Nasty hack to prevent adding
5884 symbols to symtab again if a module is loaded more than once.
5885 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
5887 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
5888 possible NULL pointer dereference.
5890 * m4/module.c (m4_module_find_by_modname): Renamed from
5891 m4_module_modname_find. Fixed all references.
5892 (m4_module_find_by_builtin): New function.
5894 * modules/modfreeze.test: load the `load' module with each
5896 * src/freeze.c (produce_frozen_state): Simplified in light of
5897 module field in m4_symbol. Allow a third argument for text macros
5898 to name the originating module.
5899 (reload_frozen_state): ditto.
5900 * m4/m4module.h: Fixup prototypes.
5901 * m4/builtin.h (m4_builtin_define): Add a module argument so
5902 that symbols can be registered against the defining module.
5903 (m4_macro_define): ditto.
5904 * m4/m4private.h (m4_symbol): Make the module field const to save
5905 on casting in the rest of the code.
5906 (SYMBOL_MODULE): New macro.
5908 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
5909 symbol reference maintenance bugs when removing a symbol from the
5912 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
5914 2000-11-27 Gary V. Vaughan <gary@gnu.org>
5916 * configure.in (m4_cv_func_obstack): A better check for whether
5917 libc has an obstack implementation.
5918 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
5920 * configure.in (--with-modules): Changed semantics. This
5921 option is now used to list modules to be preopened.
5922 * src/m4.h: #include "ltdl.h" unconditionally.
5923 * src/main.c: Removed all dependencies on WITH_MODULES.
5924 * src/freeze.c: ditto.
5925 * modules/Makefile.am: ditto.
5926 * m4/m4.c (builtin_m4exit): ditto.
5927 * modules/modpath1.test: ditto.
5928 * modules/modpath2.test: ditto.
5929 * modules/modpath3.test: ditto.
5930 * modules/modpath4.test: ditto.
5931 * modules/modtest.test: ditto.
5932 * modules/shadow.test: ditto.
5933 * modules/unload.test: ditto.
5935 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
5936 comes up on demand in LTLIBOBJS now.
5937 * configure.in (getopt_long): Creating and relying on a link for
5938 getopt.h on hosts with no getopt_long() of thier own works
5939 correctly now. This is necessary so that callers of getopt_long()
5940 can simply `#include <getopt.h>': the naive way of doing this
5941 would end up using our own getopt.h and the installed
5942 getopt_long(), which is asking for trouble!
5943 (obstack_init): A similar argument applies to obstack.h and
5946 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
5947 On Solaris-2.5 (at least) the native dlopen implementation
5948 gets confused about m4.o when looking for module "m4". This
5949 version always looks for .la an .$lib_ext suffixed names first
5950 to work around the problem. Sigh.
5952 * po/POTFILES.in: Take account of these file movements.
5953 * src/Makefile.am (m4_SOURCES): removed eval.c.
5954 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
5955 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
5956 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
5957 * modules/m4.c (builtin_eval): Use m4_evaluate().
5958 * m4/eval.c: Moved here from src/eval.c to facilitate
5959 implementation of eval() builtin as part of the `m4' loadable
5961 (m4_evaluate): renamed from evaluate for namespace cleanliness.
5962 * m4/numb.c: Moved here from src/numb.c, since it is #included
5963 into eval.c at compile time.
5964 * m4/m4module.h (m4_evaluate): Added prototype.
5965 * src/m4.h (evaluate): Removed prototype.
5967 2000-11-25 Gary V. Vaughan <gary@gnu.org>
5969 * modules/perl.c (builtin_perleval): Use PL_na for
5970 compatibility with perl-5.6.
5972 * src/main.c (main): It is now safe to
5973 ``m4_module_install("m4")'', without tripping over the m4
5975 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
5976 versions having fixed the insidious module search order bug.
5978 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
5979 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
5981 * configure.in: Figure out whether to use the installed
5982 getopt.h or the supplied one.

6322 src dir and immediately after libm4 is built for confidence that
6323 it doesn't rely on the src directory.
6324 (SUBDIRS): Moved doc dir to the end since helptoman.pl and
6325 makeinfo stop the build on cygwin (because they don't work).
6327 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
6329 * m4/m4private.h: ...is not a public header, so moved to src.

6373 From Akim Demaille <akim@epita.fr>
6375 2000-01-17 Gary V. Vaughan <gary@gnu.org>
6377 * src/ltdl.c: Use access() to abort doomed module load attempts
6378 if module file does not exist.
6380 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
6381 getopt1.o will already be used if appropriate, so I moved getopt.c
6382 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.

6385 * modules/modpath2.test: ditto.

6391 generates a spurious error message which spoils most of the tests:
6392 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
6393 (TESTS): s/test.test /modtest.test /
6394 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /

6442 * lib/COPYING.LIB: updated to version 2.1.
6444 * lib/m4module.h: restructure the M4_SCOPE code to work when
6445 creating a dll which links with libm4.la and both DLL_EXPORT
6446 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
6449 2000-01-11 Gary V. Vaughan <gary@gnu.org>
6451 Merged the following changes from my tree:
6453 1999-06-15 Gary V. Vaughan <gary@gnu.org>
6455 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
6456 ported to compile shared libs.
6458 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
6459 use `__declspec(dllimport)' when linking libm4.la on win32.
6460 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
6462 * configure.in (M4OBJS): Discover whether we need the shipped
6463 implementation of getopt_long.
6464 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
6465 main binary here, as opposed to the module library in lib/libm4.la.
6467 1999-06-14 Gary V. Vaughan <gary@gnu.org>
6469 * modules/README: Updated to describe the improved libltdl based
6471 * README (cygwin): Added some compilation notes for building m4
6472 correctly under cygwin.
6473 * TODO: Cleaned out the entries for the module system since they
6474 are now implemented.
6476 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
6477 all instances of __P with M4_PARAMS.
6479 * lib/getdate.h: removed unreferenced file.
6481 * lib/m4private.h: New file to define the private interface to the
6482 token_data struct, which must be shared between m4module.c, and
6483 builtin.c but not exported to modules built from the installed
6484 m4module.h since it's size changes depending on compile time
6487 * src/m4.h: Lots of stuff moved to lib/m4module.h.
6489 * lib/m4module.h: New file to define the interface available when
6490 compiling m4 modules.
6491 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
6492 necessary for module compilation into this new file.
6494 * lib/Makefile.am (include_HEADERS): install headers (renamed to
6495 avoid nameclash with other system headers) necessary for compiling
6497 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
6498 so that modules can include the (renamed) installed headers and
6499 be guaranteed a matching implementation.
6500 * lib/m4error.h: renamed from error.h.
6501 * lib/m4obstack.h: renamed from obstack.h.
6502 * lib/m4regex.h: renamed from regex.h.
6503 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
6504 implementation, simply include the shipped version
6505 unconditionally, otherwise it is hard for a module to know
6506 whether the m4obstack.h header it is using matches the
6507 implementation it ends up linking against.
6508 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
6511 1999-05-18 Gary V. Vaughan <gary@gnu.org>
6513 * examples/misc.test: Don't run this test on machines which don't
6514 have a root user in /etc/passwd (e.g. cygwin).
6516 * tests/get-them (/^@example$/): Error messages might have a
6517 ``.exe'' suffix to the program name, or else use the libtool
6518 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
6519 of these cases are now catered for when comparing error messages
6521 * tests/other-tests/*.test: ditto.
6522 * examples/*.test: ditto.
6524 * tests/defs (M4): use libtool execute mode.
6525 * examples/defs (M4): ditto.
6527 * tests/get-them (END): explicitly close any open file.
6528 (printthem): In a regular expression, '{' is the start of a repeat
6529 count! Use `[{]' for a literal open brace.

6572 with some compilers (found and fixed by James Bonfield
6573 <jkb@mrc-lmb.cam.ac.uk>).
6575 * src/stackovf.c: Added prototypes for ultrix.

6626 1999-11-09 Paul Eggert <eggert@twinsun.com>
6628 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
6629 and zero, as Solaris 7 cc does.
6630 (bcopy): Remove macro; no longer needed with new obstack.h.
6632 * src/output.c (freeze_diversions): Don't assume that a
6633 diversion size can fit in `int'. Check for diversion file
6634 size too large to be printed with `unsigned long'.
6636 * src/Makefile.am (CFLAGS): Omit -Wall.
6638 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.

6669 are modules, not linktime libraries.
6670 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
6671 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
6672 avoidance on exported symbols.

6680 into running executable before reading the source.
6681 (--module-directory): prepend a directory to the module search
6683 (module_init()): Do this the first time we load a module instead;
6684 if the module subsystem is broken normal m4 scripts can still run.

6705 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
6706 * acm4/gettext.m4: removed. It causes a multiple definition vs.
6707 the installed gettext.m4 file when running aclocal.
6709 1999-03-25 Gary V. Vaughan <gary@gnu.org>
6711 * configure.in (AM_INIT_AUTOMAKE): bumped version number to

6724 the module code is broken.
6725 * src/m4.h (module_init): removed. No longer relevant.
6726 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on

6729 m4_finish_module): ditto.
6730 * modules/time.c (m4_macro_table): ditto.
6732 * bootstrap: New file. Runs all the autoutils in the right order
6733 after a fresh checkout, or a make maintainer-clean.

6752 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
6754 * src/module.c (module_try_load): Don't try to be clever and
6755 overwrite argument string. Instead allocate all constructed
6756 strings locally, since they can have arbitrary lengths. Make
6757 arguments pointers to const.
6758 (module_search): Simplify due to above change.
6760 1998-11-29 René Seindal <rene@seindal.dk>
6764 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): New tests.

6788 * src/m4.c (main): New option --import-environment (no single
6791 * When configured with --with-gmp both the normal (fast) eval()
6792 and the gmp aware mpeval() are defined. To restore previous
6793 bahaviour use "define(`eval', defn(`mpeval'))".
6795 * tests/other-tests/gmp.m4: Changed to use mpeval().
6797 * src/evalmp.c: New file for compiling eval.c as gmp aware.
6798 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
6800 * src/eval.c: Now includes "numb.c" directly. Everything in this
6801 file must by static, except evaluate(), which is changed to
6802 mp_evaluate() if USE_GMP in force.
6804 * src/numb.c: Changed to be included by eval.c instead of being
6805 compiled separately. Everything is declared static.
6807 * src/numb.h: Removed declarations of functions, as numb.c is now

6820 * src/m4.c (main): m4 --version also shows which options were used
6821 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
6823 1998-11-27 René Seindal <rene@seindal.dk>
6825 * Error messages now always print program name before input file
6826 name as specified by GNU coding standards. Reported by Akim
6827 Demaille <demaille@inf.enst.fr>.
6829 * doc/m4.texinfo (Include): Change due to changed error message
6833 * tests/get-them: Minor change to sed script due to changed error
6836 * src/m4.c (print_program_name): New func used to print program
6837 name, input file and line number in error (). Used as an
6838 error_print_progname handler.
6839 (reference_error): Removed.
6840 (main): Assigns error_print_progname.
6842 * src/m4.h (M4ERROR): Removed reference_error ().

6849 warning of ambiguous 'else'.
6851 * src/module.c: Inserted search path code from path.c modified to
6853 (module_init): Configured default path used only if M4MODPATH is
6855 (module_try_load): Now reads libMODULE.la as generated by libtool
6856 for actual module name.
6857 (module_load): Gives better error messages on failure.

6867 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
6868 included gettext, as <libintl.h> might not be found
6869 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
6871 1998-11-22 René Seindal <rene@seindal.dk>
6873 * src/output.c (insert_diversion): Fixed bug that might cause m4
6874 to read from standard output! Triggered by input
6875 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
6876 so now 'undivert(0)' does nothing.
6878 1998-11-18 René Seindal <rene@seindal.dk>
6882 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
6883 could be changed when compiling a illegal regexp, causing later

6902 * modules/Makefile.am: Changed completely to compile modules using
6903 libtool. The modules are compiled as shared libraries, and are
6904 renamed when installed.
6906 * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
6907 USE_SHL_LOAD to HAVE_SHL_LOAD
6909 * src/builtin.c (shipout_string): Now tests for a NULL string.

6939 These two are now initialised by autoconf macros.
6941 * src/path.c (module_env_init): MODULE_PATH is always on the
6944 * src/Makefile.am: Now generated pathconf.h which defined the
6945 default MODULE_PATH.
6947 * configure.in (pkglibexecdir): Added defintion of pkglibexecdir,
6948 where modules are installed.
6950 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
6951 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
6952 build and install automatically, and it is prepared for other
6953 interfacec than dlopen().
6955 * src/builtin.c (predefined_tab): Added __m4_version__ for the
6956 current version of GNU m4. It is a GNU extension.

7117 * configure.in: Added code to implement --with-modules. Tests for
7120 * acconfig.h: Added WITH_MODULES
7122 1998-10-02 René Seindal <rene@seindal.dk>
7124 * examples/Makefile.am (pkgdata_DATA): Removed special target for
7125 check and variables TESTS. These tests are now run from the
7128 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
7129 directory. The files stay there but the tests are run from the
7132 * tests/Makefile.am (EXTRA_DIST): Added run-test.
7134 * tests/run-test: New file. Run a test manually
7136 * tests/Makefile.am, tests/get_them: Moved automatically generated
7137 tests (from the manual) to sub directory tests/gentest/. The
7138 tests/ directory had gotten a bit messy.
7140 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
7142 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\
7143 wrap}.test: Added a few testcases.
7145 1998-08-21 Erick Branderhorst <Erick.Branderhorst@asml.nl>
7149 * lib/Makefile.am (noinst_HEADERS): regex.h added
7151 * configure.in (jm_WITH_REGEX, jm_PREREQ_ERROR):
7152 acm4/{error,regex}.m4 (from fileutils-3.16u.tar.gz).
7154 * acm4/Makefile.am: created providing rules to create
7155 $(top_srcdir)/acinclude.m4 to be used by aclocal.
7157 * tests/defs (LANGUAGE, LC_ALL, LANG): force them to be
7158 `C'. Reported by Ulrich Drepper.
7160 * Makefile.am (SUBDIRS): Removed checks directory
7161 * configure.in (AC_OUTPUT): Removed checks/Makefile
7163 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
7164 the space when m4.texinfo is edited and whitespace.el is active.
7165 (Defn,example): idem.
7167 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
7169 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
7170 ../COPYING. ../Makefile is a file which is certainly present when
7171 test is executed in testSubDir. One can't be sure that the COPYING
7172 file is in .. or ../.. in all situations, the ../Makefile is
7175 * doc/m4.texinfo (Include): adjusted expected test output
7176 according to new tests, i.e. the input will always come from the
7177 file `in' created by the test.
7179 * tests/Makefile.am: Added three lines at the top to get
7180 esyscmd.1.test working.
7182 * tests/get-them: modified to generate clearer tests who will need
7183 less maintenance when new test examples are created in
7184 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
7185 need the generic file `defs') shell scripts creating `in', `ok',
7186 `out' and when apropriate `okerr' and `err' in the directory
7187 `testSubDir' when executed. The compare of `ok' and `out'
7188 (and of `okerr' and `err') will be the exit status of the test.
7189 `out' must match `ok' (and `okerr' must match `err') for the test
7192 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
7193 the tests generated by tests/get-them getting it input normally
7194 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
7195 (dot) before the numeric part) is reserved for all other (hand
7196 written) tests. The `+' means one or more times.
7198 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
7200 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
7201 supported short man page to refer to info documentation
7202 * helptoman.pl: added
7203 * configure.in: AC_PATH_PROG(PERL,perl)
7204 * Makefile.am (SUBDIRS): doc after src
7206 * libitized with libit 0.5 from
7207 ftp://ftp.iro.umontreal.ca/pub/contrib/pinard/maintenance/libit.

7227 * src/builtin.c (m4_changesyntax): Added builtin macro
7228 "changesyntax" to modify the syntax table.
7230 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax
7231 table. All categories are assigned a syntax code and tokens are
7232 read according to this table.
7234 1998-08-09 René Seindal <rene@seindal.dk>
7236 * src/numb.{c,h}: New files, implements multiple precision eval
7237 using GNU gmp. Originally submitted by John Gerard Makecki
7238 (johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.
7240 * doc/m4.texinfo (Eval): Added documentation for multiple
7241 precision arithmetic library support.
7243 * src/m4.{c,h}, src/eval.c, src/builtin.c, configure.in: Changes
7244 to accommodate multiple precision eval.
7246 1998-08-07 René Seindal <rene@seindal.dk>

7265 and _ macro. M4 now builds with --disable-nls.
7267 * src/m4.c (main): reintroduced textdomain(PACKAGE) to get gettext
7268 to look for right message catalogs. Call indef'ed by ENABLE_NLS.
7270 * configure.in (ALL_LINGUAS): Added complete list of translations:

7296 Used libitize (0.4) to update.
7298 * configure.in, ABOUT-NLS, intl/*, po/*: Added gettextize
7299 (0.10.25) support. Removed LOCALE, fr.msg, m4.cod and adjusted

7359 * src/macro.c (collect_arguments): Cast obstack arguments to
7360 (voidstar), so avoiding compiler warnings.
7361 Reported by Joseph E. Sacco.

7403 Remove the sed filter after ansi2knr for debug.c. Use $O instead
7404 of $U, put underline in extensions rather than in basenames. Use
7405 implicit rules, now that regularity makes this possible.
7406 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
7407 of ansi2knr whenever it is needed.
7408 * configure.in: Adjusted for correct STACKOVF substitution.
7409 * src/debug.c (trace_format): When not __STDC__, use (...) as a

7428 * {,/*}Makefile.in: Use && after all cd, in case they fail.
7430 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

7515 * Makefile.in (stamp-h.in): Idem.
7517 * Makefile.in (distclean, realclean): Force serial execution of

7663 * freeze.c: New file.
7664 * Makefile.in: Compile it, distribute it.
7665 * m4.c: Recognize, document and process --freeze-state (-F) and
7666 --reload-state (-R) options. Pass a true flag to builtin_init
7667 only if no reloading some state.

7678 * configure.in: Implement --with-dmalloc.
7679 * acconfig.h: Document WITH_DMALLOC.
7680 * m4.h: Add code for when WITH_DMALLOC.
7682 1994-08-15 François Pinard <pinard@iro.umontreal.ca>
7684 * m4.c (long_options): Use "error-output", the dash was missing.
7685 Reported by Akiko Matsushita.
7687 1994-08-12 François Pinard <pinard@iro.umontreal.ca>
7689 * m4.h: Include <sys/types.h>.
7690 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
7691 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
7693 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
7695 * builtin.c (dump_args): Declare len as size_t, not int.
7697 * debug.c: Prototype the forward declaration of debug_set_file.
7699 * builtin.c (m4_undivert): Replace div by file, for avoiding the
7700 shadowing of this variable.
7701 * output.c (insert_diversion): Idem.
7703 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
7704 (input_init): Duplicate default quote and comment strings.
7705 (set_quotes): Free previous quote strings in all cases. Duplicate
7706 even default quote strings.
7707 (set_comment): Free previous comment strings in all cases.
7708 Duplicate even default comment strings.
7710 * configure.in: Updated for Autoconf 2.0.
7711 * Makefile.in (distclean-local): Also delete config.cache.
7713 * m4.c (usage): Reorganize the --help output by topic. Include a
7714 description for debugging flags.
7716 1994-07-29 François Pinard <pinard@iro.umontreal.ca>
7718 * configure.in: If sigaction is available and SA_ONSTACK defined,
7719 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
7720 defined, use sigvec. Else don't compile stackovf.c.
7721 * stackovf.c (setup_stackovf_trap): Idem.
7722 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
7725 1994-07-21 François Pinard <pinard@iro.umontreal.ca>
7727 * m4.c (usage): Replace printf par fputs.
7729 1994-07-18 François Pinard <pinard@iro.umontreal.ca>
7733 1994-07-17 François Pinard <pinard@iro.umontreal.ca>
7735 * configure.in: Check for sigaction and sigvec. Add a new delayed
7736 check for RLIMIT_STACK, combine in the checking for getrlimit.
7737 All those things are not universally available.
7738 * stackovf.c: Split setting up the trap handler and catching
7739 signals, for better taking care of various configure outcomes.
7740 * examples/stackovf.sh: Correct a typo.
7741 Reported by Eric Backus, Jim Avera and Jim Meyering.
7743 1994-07-16 François Pinard <pinard@iro.umontreal.ca>
7745 * ansi2knr.c: New version sent by its author, Peter Deutsch.
7747 1994-07-15 François Pinard <pinard@iro.umontreal.ca>
7749 * Makefile.in: Modify so parallel make will not try making
7750 lib/libm4.a twice simultaneously.
7751 Reported by Jim Meyering.
7753 1994-07-14 François Pinard <pinard@iro.umontreal.ca>
7755 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
7756 error message, for when no code possibility exists. Even if this
7757 line is completely #ifdef'ed out, it brings a syntax error.
7758 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
7760 * Makefile.in (install): Have install depend on all too, for lib
7761 to be remade as needed.
7763 * examples/stackovf.sh: Try ksh, bsh and bash for shells
7764 providing ulimit, instead of using only ksh.
7765 Reported by Jim Avera and Joseph E. Sacco.
7767 1994-07-12 François Pinard <pinard@iro.umontreal.ca>
7769 * Makefile.in (check): Have it depend on all instead of m4. In
7770 this way, a change in lib will be detected and processed.
7772 * builtin.c (numeric_arg): Use strtol and verify the conversion,
7773 instead of using sscanf which stops as soon as there is a
7774 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
7775 and divert(1xyzzy) were all accepted without any warning or error
7777 * m4.h: Declare strtol as long if not including stdlib.h.
7778 * configure.in: Check for limits.h, and replace strtol if missing.
7779 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
7780 * lib/strtol.c: New file, from elsewhere.
7781 Reported by Andreas Schwab.
7783 1994-07-07 François Pinard <pinard@iro.umontreal.ca>
7785 * macro.c (expand_macro): Cast value to (boolean) prior to
7786 assigning it to traced.
7787 Reported by Tom McConnell.
7789 * Makefile.in (m4): Always make all in lib first.
7790 Reported by Jim Meyering.
7792 1994-07-06 Jim Avera <jima@netcom.com>
7794 * stackovf.c: Isolated OS-dependent sections; Improved portability,
7795 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
7796 handlers), and a default error message if the fault address is not
7797 available (when neither siginfo.h nor BSD sigcontext are supported).
7798 * configure.in: Changes for stackovf.h: Check for sigcontext,
7799 sigaction, sigstack, and define rlim_t as int if necessary.
7800 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
7801 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
7802 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
7804 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
7806 * configure.in: Use AC_SET_MAKE.
7807 * Makefile.in: Use @SET_MAKE@.
7808 Reported by Jim Meyering.
7810 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
7811 Reported by Ian Taylor.
7813 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
7815 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
7816 because siginfo.h is unrelated to standard headers, and siginfo.h
7817 is already checked for.
7818 Reported by Joseph E. Sacco.
7820 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
7822 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
7825 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
7827 * builtin.c (substitute): Use \& to represent this part of the
7828 string which was matched by the whole regexp, instead of
7829 representing the whole string. Any usage of \0 issues a warning
7830 and acts like \&, it will disappear in some subsequent release.
7832 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
7834 * m4.c: Complete prototype for forwarded declaration of usage.
7836 * input.c (init_macro_token): Correct own reference in error
7837 message. Previous name get_macro_func was referred to instead.
7838 (next_char): Correct own reference in error message. Previous
7839 name advance_input was referred to instead.
7841 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
7842 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
7843 and_term, not_term, logical_not_term, cmp_term, shift_term,
7844 add_term, mult_term, exp_term, unary_term, simple_term): Add
7845 prototype to forwarded declarations. Declare parameter v1 as
7846 eval_t * instead of int *. Same for local variable v2 in dyadic
7847 functions. Same for result in exp_term.
7848 * builtin.c (m4_eval): Declare value as eval_t instead of int.
7849 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
7850 unsigned_eval_t instead of unsigned int. Change casts accordingly.
7851 (shipout_int): Cast first argument of ntoa to eval_t.
7852 Reported by Thorsten Ohl.
7854 * macro.c: Complete the prototypes of forwarded expand_macro and
7856 Reported by Thorsten Ohl.
7858 * m4.h: Define voidstar as void * or char * depending on __STDC__.
7859 The Ultrix 3.1 compiler cannot do much with void pointers.
7861 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
7862 * m4.c (xfree): Replace void * by voidstar.
7863 Reported by Tom McConnell.
7865 * ansi2knr.1: New, from elsewhere.
7866 * Makefile.in (DISTFILES): Distribute ansi2knr.1
7868 * Makefile.in (stamp-h.in): Avoid running ./config.status if
7869 stamp-h does not exist yet. This avoids running it a second time
7870 just after the initial ./configure.
7871 Reported by David MacKenzie and Tom McConnell.
7873 * m4.h: Replace the enum debug_info declaration with a series of
7874 #define's. The Ultrix 3.1 compiler would otherwise need casting
7875 (int) to most references, when used in expressions.
7876 Reported by Tom McConnell.
7878 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
7880 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
7881 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
7882 calls the compiler. Previously, FP_PROTOTYPES was only calling
7883 the preprocessor; by not being subject to CFLAGS, this was
7884 discouraging those flags asking for ANSI compilation.
7885 * acconfig.h: Document HAVE_PROTOTYPES.
7886 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
7887 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
7888 Reported by Eric Backus.
7890 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
7891 from the environment. Default CFLAGS to -g if not set.
7892 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
7893 * lib/Makefile.in: Have CFLAGS substituted from configure.
7894 Reported by Eric Backus and Tom McConnell.
7896 * configure.in: m4_undefine changeword before using AC_ENABLE.
7898 * m4.h: Declare prototypes for error (for ANSI compilers only),
7899 prefix_all_builtins and reference_error.
7900 Reported by Tom McConnell.
7902 * input.c (set_word_regexp): Do not try to initialize the array
7903 test from a string, this does not work with non-ANSI compilers.
7904 Reported by Eric Backus.
7906 * Makefile.in (dist): Clean examples/ before saving it.
7907 (distclean-local): Also remove stamp-h.
7908 Reported by Eric Backus.
7910 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
7912 Reported by Tom McConnell.
7914 * checks/Makefile.in (clean): Depends on mostlyclean.
7915 (mostlyclean): New goal.
7917 1994-06-24 François Pinard <pinard@iro.umontreal.ca>
7919 * Makefile.in (DISTFILES): Distribute install.sh.
7920 * install.sh: New file, copied from elsewhere.
7921 Reported by Assar Westerlund and Kaveh R. Ghazi.
7923 1994-06-23 François Pinard <pinard@iro.umontreal.ca>
7925 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
7926 * acconfig.h: Explain ENABLE_CHANGEWORD.
7928 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
7929 from code provided by Pete Chown]
7930 * m4.h: Add original_text field to u_t variant of union u.
7931 Declare TOKEN_DATA_FUNC macro.
7932 * builtin.c: Declare changeword.
7933 (m4_changeword): New function.
7934 * input.c: Include "regex.h", define variables with word regexps.
7935 (input_init): Initialize the word regexp.
7936 (set_word_regexp): New.
7937 (next_token): Declare local variables, use the previous code if
7938 default_word_regexp is true. Else, match using a new code. Save
7940 * macro.c (expand_token): Ship out original text if not a macro
7942 Reported by Krste Asanovic and Pete Chown.
7944 [These modifs all depend upon ENABLE_CHANGEWORD]
7945 * m4.h: Declare external user_word_regexp.
7946 * m4.c: Declare user_word_regexp, and initialize it from
7947 --word-regexp or -W, or NULL if not specified.
7948 * input.c: Use user_word_regexp if specified, instead of
7949 DEFAULT_WORD_REGEXP.
7951 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
7954 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
7955 * checks/Makefile.in: Empty the suffix list.
7956 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
7958 * m4.c: Declare nesting_limit and initialize it to 250.
7959 Implement -LNUMBER or --nesting-limit=NUMBER to change its
7961 * m4.h: Declare nesting_limit as external.
7962 * macro.c (expand_macro): Stop execution whenever nesting limit
7964 Reported by Bengt Mertensson.
7966 * eval.c (evaluate): Diagnose excess characters in eval input.
7967 Things like `eval(08)' used to return 0 with no diagnostic.
7969 * m4.h: Capitalize first letter of all macro arguments in
7972 * m4.c: Declare warning_status, initialize it to 0. Add new
7973 option -E, or --fatal-warnings, which sets warning_status to
7974 EXIT_FAILURE instead.
7975 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
7976 EXIT_FAILURE if not otherwise done by header files.
7977 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
7978 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
7979 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
7980 argument of all M4ERROR calls.
7981 Reported by Noah Friedman.
7983 * examples/incl-test.m4: Renamed from incl_test.m4.
7984 * examples/include.m4: Include incl-test.m4 instead of
7986 * examples/multiquotes.m4: Renamed from multi-quotes.m.
7988 1994-06-22 François Pinard <pinard@iro.umontreal.ca>
7990 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
7991 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
7992 also tested it on a Sun Sparc workstation running SunOS 4.x.
7994 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
7995 49.format check, abusing a `union values' argument with sprintf
7996 without selecting the proper field. Now, save the formatting type
7997 first, delaying the fetch of the corresponding argument.
7998 Reported by Joseph E. Sacco and Tom Quinn.
8000 * format.c (format): Remove const from char *fmt declaration when
8001 not HAVE_EFGCVT, because a NUL may be forced into it.
8003 * m4.h: Declare atof() when not STDC_HEADERS.
8004 Reported by Joseph E. Sacco.
8006 * Regenerate configure using Autoconf 1.11, this corrects a
8007 problem about an incorrect cpp seting on NeXT 3.1.
8008 Reported by Alexander Lehmann.
8010 1994-06-05 François Pinard <pinard@iro.umontreal.ca>
8012 * m4.h (_): Change argument from `x' to `Args'.
8014 1994-04-22 François Pinard <pinard@iro.umontreal.ca>
8016 * m4.h: Rename Args() to _().
8017 * m4.h: Remove extern specifier from all function declarations.
8019 1994-04-22 Jim Avera <jima@netcom.com>
8021 * stackovf.c: New file implementing stack-overflow detection.
8022 * configure.in: Check for getrlimit, sigaction. If all of
8023 standard headers, getrlimit and sigaction, define USE_STACKOVF and
8024 substitute ${U}stackovf.o for STACKOVF.
8025 * acconfig.h: Declare USE_STACKOVF.
8026 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
8027 * m4.h: Declare setup_stackovf_trap().
8028 * m4.c: Call setup_stackovf_trap().
8029 * tests/stackovf_test.sh: New file.
8031 1994-04-13 François Pinard <pinard@iro.umontreal.ca>
8033 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
8035 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
8037 1994-01-30 François Pinard <pinard@iro.umontreal.ca>
8039 * m4.h: Remove definition of volatile, not used anymore.
8040 Reported by Jim Meyering and Joseph E. Sacco.
8042 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
8043 of `if ... else /* nothing */' for if macros.
8044 Reported by Jim Meyering.
8046 * builtin.c (m4_regexp): Reorganize the code for avoiding a
8047 warning from gcc about `repl' possibly used before defined.
8048 Reported by Jim Meyering.
8050 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
8051 Reported by Jim Meyering.
8053 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
8055 * m4.h: Move the conditional definition of volatile after the
8056 inclusion of system files, because they may define it first.
8058 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
8060 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
8061 get around a problem with Alpha make seeing a syntax error, there.
8062 Reported by Vern Paxson.
8064 1994-01-03 François Pinard <pinard@iro.umontreal.ca>
8066 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
8067 Reported by Richard Stallman.
8069 1993-12-25 François Pinard <pinard@iro.umontreal.ca>
8071 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
8072 instead of AC_HAVE_FUNCS.
8073 Reported by Noah Friedman.
8075 1993-12-01 François Pinard <pinard@iro.umontreal.ca>
8077 * m4.c: Initialize show_help and show_version to zero.
8079 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
8080 Use them in exit() and usage() calls.
8082 1993-11-27 François Pinard <pinard@iro.umontreal.ca>
8084 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
8085 syserr() macro. Delete errref, add reference_error and M4ERROR.
8086 * m4.c: Replace errref, which was returning an input reference
8087 string, with reference_error, which prints it on standard error.
8088 * builtin.c, output.c: Use errno as second parameter to error,
8089 instead of using syserr() with %s.
8090 * *.c: Use M4ERROR instead of error: no more errref() with %s.
8091 Doing so, the program name appears after the input reference
8092 instead of before, which eases M-x next-error processing.
8094 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
8096 * checks/get-them: Escape braces with backslashes in patterns,
8097 because HPUX-9.01 awk needs this.
8098 Reported by Jim Meyering.
8100 1993-11-22 François Pinard <pinard@iro.umontreal.ca>
8102 * builtin.c: Declare "FILE *popen ();".
8104 * m4.h: Remove MESSAGE{,1,2}, WARNING1, FATAL{,1}, INTERNAL_ERROR
8105 macros, replace error_message_prefix() declaration by errref()'s.
8106 Declare xrealloc, for use in errref().
8107 * m4.c: Delete error_message_prefix() function, add errref().
8108 * *.c: Use error() systematically in place of all error macros,
8109 now that error() flushes stdout first. Make needed adjustments.
8111 * m4.h: Remove const in sys_errlist[] declaration, it creates
8112 conflicts on SGI and Alpha.
8113 Reported by Kaveh R. Ghazi.
8115 1993-11-20 François Pinard <pinard@iro.umontreal.ca>
8117 * m4.c: Include <getopt.h> instead of "getopt.h".
8119 * configure.in: Output to config.h. Use HAVE_FUNCS preferably.
8120 * acconfig.h: New, for documenting HAVE_EFGCVT.
8121 * Makefile.in: Distribute acconfig.h, .stamp-h.in and config.h.in,
8122 use them wherever appropriate. Also use -I. for compilations.
8123 * lib/Makefile.in: Use -I.. for compilations.
8124 * *.c: Include <config.h> or "config.h".
8126 * m4.h: Test for HAVE_MEMORY_H instead of NEED_MEMORY_H.
8127 * configure.in: Use AC_HAVE_HEADERS(memory.h), delete AC_MEMORY_H.
8129 1993-11-17 François Pinard <pinard@iro.umontreal.ca>
8131 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
8133 * input.c (input_init): Initialize quote and comment strings
8134 explicitely instead of calling set_quotes and set_comment: by
8135 doing so, we ensure we do not free uninitialized variables.
8137 * checks/check-them: Reverse arguments to both diff, so the
8138 expected is on the left and the obtained on the right.
8140 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
8141 macros. Delete declarations for m4error, warning, fatal and
8142 internal_error, add declaration for error_message_prefix.
8143 * m4.c: Delete m4error, warning, fatal and internal_error
8144 routines, add error_message_prefix routine.
8145 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
8146 warning with WARNING*, fatal with FATAL* and internal_error with
8148 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
8149 this is not needed anymore.
8151 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
8152 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
8153 and debug_message, add declaration for debug_message_prefix.
8154 * debug.c: Remove static specifier for FILE *debug declaration.
8155 Delete debug_print and debug_message routines, add
8156 debug_message_prefix routine.
8157 * builtin.c, debug.c: Replace debug_print routine calls with
8158 DEBUG_PRINT* macro calls.
8159 * input.c, path.c: Replace debug_message routine calls with
8160 DEBUG_MESSAGE* macro calls.
8162 * m4.h: Remove inclusion of <varargs.h>.
8163 * debug.c: Include <stdarg.h> or <varargs.h>.
8164 (trace_format): Use stdarg instead of varargs if __STDC__.
8166 * configure.in: Remove checks for vfprintf and _doprnt. These
8167 implementations use varargs tricks which are not portable enough.

8390 1993-01-17 François Pinard <pinard@iro.umontreal.ca>
8392 * Makefile.in, lib/Makefile.in: Put $(CFLAGS) after $(CPPFLAGS),
8393 so the installer can override automatically configured choices.
8394 Reported by Karl Berry.
8396 1993-01-15 François Pinard <pinard@iro.umontreal.ca>
8398 * lib/vfprintf.c: Stolen from Oleo distribution and adapted. The

8410 Richard wants it there.
8412 1992-12-27 François Pinard <pinard@iro.umontreal.ca>
8414 * Makefile.in: Add DEFS to MDEFINES.

8424 macro.c, output.c, path.c, symtab.c: Change Copyright from
8425 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
8427 * examples/divert.m4: Deleted, this bug has been corrected.
8429 * Makefile.in (texclean, mostlyclean): New goals.
8431 * Makefile.in (clean): Remove clutter from ansi2knr.
8432 Reported by Pierre Gaumond.
8434 1992-12-20 François Pinard <pinard@iro.umontreal.ca>
8436 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user

8447 1992-12-19 François Pinard <pinard@iro.umontreal.ca>
8450 This is still a beta release for the future GNU m4 version 1.1.
8452 * lib/alloca.c: New, from elsewhere.
8453 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
8455 * m4.h: Do not define index/rindex if already defined. If
8456 FALSE/TRUE are already defined, do not redefine them, but merely
8457 define boolean typedef to int.
8459 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
8460 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
8461 because some C compilers do not like connectives with #ifdef.
8462 * m4.h: Define `volatile' only if __GNUC__, instead of once for
8463 __GNUC__ and once for __STDC__.
8464 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
8466 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
8467 Makefile dependencies. Without it, make keeps destroying and
8468 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
8470 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
8471 to diversion/DIVERSION, this was a spelling error.
8473 * m4.c: Declare version[], remove #include "version.h".
8474 * version.h: Deleted.
8475 * Makefile.in: Remove references to version.h.
8477 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
8478 production, by using a simpler and more robust algorithm. This
8479 solves the problem of synclines sometimes written in the middle of
8480 an output line. Delete sync_line() and output_lines variable.
8481 * m4.h: Remove sync_line prototype and output_lines declaration.
8482 * input.c (next_char), output.c (shipout_text): Remove references
8484 * input.c (push_file, pop_file): Merely put the value -1 in
8485 output_current_line instead of calling sync_line, for delaying a
8486 single `#line NUM FILE' before next output line. Do not test
8487 for sync_output, because this is unnecessary clutter.
8488 * output.c (make_divertion, insert_divertion): Idem.
8489 * input.c: Rename must_advance_line to start_of_input_line, for
8492 * debug.c (trace_header): Select a new debug line format, which
8493 better complies with GNU standards for formatting error messages.
8494 With option `-dfl', M-x next-error might be used on the output.
8495 * m4.c (vmesg): Adjust format of error output to GNU standards.
8496 * m4.texinfo: Adjust examples for `make check' to work.
8498 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
8499 case for enum debug_info constants, which were all lower case.
8501 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
8503 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
8504 collected patches. I tried a few times using newer regex.[ch], it
8505 mysteriously stopped aborting with this one. Insecure feeling...
8506 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
8508 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
8510 * m4.c: Change `--no-warnings' to `--silent'.
8511 Reported by David MacKenzie.
8513 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
8514 leave it off for now. See comment in m4.c for justification.
8515 Reported by David MacKenzie.
8517 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
8518 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
8520 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
8522 * Makefile.in: Ensure recursive cleaning is done before local
8523 cleaning for all clean goals.
8525 * builtin.c (ntoa): Ensure the value is always interpreted as a
8526 signed quantity, whatever the radix is.
8528 1992-11-18 Jim Meyering <meyering@idefix>
8530 * builtin.c, format.c, input.c: Split long lines.
8531 * m4.c: Use typedef macro_definition instead of struct
8533 * symtab.c: Use typedef symbol instead of struct symbol.
8535 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
8537 * *.[ch]: Remove all trailing whitespace, in code and comments.
8539 * configure.in: Find some awk.
8540 * Makefile.in: Add $(AWK) to MDEFINES.
8541 * checks/Makefile.in: Transmit $(AWK) to get_them.
8542 * checks/get_them: Use $AWK instead of gawk. Add a close in the
8543 awk script when switching files, because without this, mawk runs
8544 out of file descriptors.
8546 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
8548 * Makefile.in (realclean): Delete m4.info*.
8549 Reported by Jim Meyering.
8551 * Makefile.in: Adjust and link with checks/Makefile.
8552 * checks/Makefile.in: New.
8553 * configure.in: Output checks/Makefile.
8555 * checks/get_them: Have the dnl header of each test more
8556 recognizable by next-error, also use a better message.
8558 1992-11-16 Jim Meyering <meyering@idefix>
8560 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
8561 And use that only if __GNUC__ since we're using it's GCC-specific
8562 semantics that tell the compiler the associated function doesn't
8565 * builtin.c (substitute): Don't use character as an array index.
8566 (dumpdef_cmp): Make formal arguments `const void *' to avoid
8567 warnings with gcc -W -Wall on systems with qsort prototype.
8568 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
8571 * eval.c (most functions): Add parentheses to assignments used
8572 as truth values go avoid warnings from gcc -Wall.
8574 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
8575 any functions that don't need external scope.
8577 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
8578 (many functions and arrays): Declare `const'.
8580 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
8582 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
8583 removing the declaration from m4.h. Also rename false to FALSE
8586 * lib/Makefile.in (Makefile): New goal.
8588 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
8589 so heavily loaded. It gets more easily overridable, calling make.
8590 Reported by Jim Meyering.
8592 * Makefile.in (dist): Get .fname from the current directory name,
8593 instead of from version.h. I need updating many files manually,
8594 when the version changes, version.h is just one of them.
8596 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
8598 * m4.h: Remove the tag `boolean' on the enum introducing typedef
8599 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
8600 Reported by Tom McConnell.
8602 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
8604 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
8605 39.cleardiv, which were describing missing or spurious newlines.
8606 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
8607 do not depend on machine word size, `/bin/false' implementation,
8608 or `wc' output format. `make check' is more dependable, now.
8610 * checks/check_them: Summarize the failed tests by listing their
8611 name, at end. If none, issue `All checks successful'. Output
8612 `Checking' instead of `Input file:'.
8614 * checks/get_them, checks/check_them: Reindented.
8616 * Makefile.in (dist): chmod a+r before making the tar file.
8618 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
8620 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
8622 * input.c (next_token): Reinitialize token_buttom just after using
8623 it as a watermark with obstack_free. Or else, a future token, big
8624 enough for triggering reallocation of the obstack chunk, could
8625 void the initialized value of token_buttom, later causing panic in
8626 obstack_free. Rename token_buttom to token_bottom everywhere.
8628 * m4.h: Before declaring errno, first include <errno.h> and
8629 ensure that it does not define errno.
8630 Reported by Richard Stallman.
8632 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
8634 * builtin.c: Define and use DECLARE macro for builtins.
8636 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
8637 argument, this is a common idiom for introducing long comments.
8639 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
8640 arguments. The last argument was silently ignored.
8642 * m4.c (cmd_error): Add a missing semicolon before va_end().
8644 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
8646 * Makefile.in: Now handle protoized sources. Define and use U.
8647 Compile and use ansi2knr with old compilers. Update DISTFILES.
8648 Add `aclocal.m4' to `configure' dependencies.
8649 * ansi2knr.c: New, from Ghostscript distribution.
8650 * configure.in: Define U through FP_PROTOTYPES for old compilers.
8651 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
8652 * aclocal.m4: New, provide FP_PROTOTYPES.
8653 * m4.h: Conditionnaly protoized through Args, save for varags.
8654 * builtin.c: Protoized. Then:
8655 Include <sys/types.h> if size_t is not defined, before "regex.h".
8656 (m4_ifelse): Fetch built-in name properly for diagnostic.
8657 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
8658 (m4_regexp): Add const to `msg' declaration.
8659 (m4_patsubst): Add const to `msg' declaration.
8660 * debug.c: Protoized, save for varargs.
8661 * eval.c: Protoized.
8662 * format.c: Protoized.
8663 * input.c: Protoized.
8664 * m4.c: Protoized, save for varargs. Then:
8665 (xfree): Accept void * instead of char *.
8666 (xmalloc): Return void * instead of char *.
8667 (xrealloc): Accept and return void * instead of char *.
8668 * macro.c: Protoized.
8669 * output.c: Protoized.
8670 * path.c: Protoized. Then cast some (char *) over xmalloc's.
8671 * symtab.c: Protoized.
8673 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
8675 * m4.texinfo: Remove directory from diagnostics in 30.include,
8676 51.eval, 56.errprint and 57.m4exit tests.
8678 * m4.h: Remove declarations for int or void system functions, they
8679 cause more conflicting trouble than they make good.
8681 * configure.in: Avoid configuration header file. Add some tests.
8682 * m4.h: Remove #include "config.h".
8683 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
8684 Then, rewritten for better compliance with GNU standards.
8686 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
8688 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
8689 because of a misplaced #endif.
8691 * Many *.[hc] files: Correct intra-line spacing here and there,
