2418 Use m4__module_next instead of obsolete lt_dlhandle_next.
2420 2005-10-20 Gary V. Vaughan <gary@gnu.org>
2422 * bootstrap (func_update_po): Update pofiles directly from the
2423 translation project.
2424 * po/LINGUAS, po/cs.po, po/de.po, po/el.po, po/fr.po, po/it.po,
2425 po/ja.po, po/nl.po, po/pl.po, po/ru.po, po/sv.po: No need to store
2426 these files under source control anymore.
2427 Suggested by Eric Blake <ebb9@byu.net>
2429 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2431 * ltdl/m4/m4-gnulib.m4: Update FSF contact address. Somehow this
2432 file escaped the address updates on 2005-05-01.
2434 2005-07-07 Gary V. Vaughan <gary@gnu.org>
2436 * bootstrap: Allow user overriding of gnulib-tool location, and
2437 correctly determine module source directories whether gnulib-tool
2438 is given as a relative or absolute path, or is found by searching
2440 Reported by Eric Blake <ebb9@byu.net>
2442 2005-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2444 * ltdl/m4/debug.m4 (m4_CHECK_DEBUGGING): Make sure that both $rm
2445 and $RM are defined for various versions of
2446 AC_LIBTOOL_COMPILER_OPTION.
2448 * bootstrap (AUTORECONF): New variable to allow user overriding of
2451 2005-07-07 Gary V. Vaughan <gary@gnu.org>
2453 * doc/m4.texinfo (History): Add better notes on the ancestory of
2454 GNU m4, and other historical interest.
2456 2005-05-08 Gary V. Vaughan <gary@gnu.org>
2458 * m4/symtab.c (m4_symbol_rename): New function that performs a low
2459 level symbol rename.
2460 * m4/m4module.h (m4_symbol_rename): Declare it as part of the API.
2461 * modules/gnu.c (regsub): Factored out of m4_epatsubst_do...
2462 (m4_patsubst_do, m4_renamesyms_do): ...wrappers that use
2464 (erenamesyms, renamesyms): ...builtins that use these to implement
2465 macro renaming by regular expression.
2466 * doc/m4.texinfo (Erenamesyms and Renamesyms): Document them.
2467 * tests/generate.awk: Allow some forbidden `m4_' prefixed symbols
2468 to stop the new generated tests from choking.
2470 2005-05-07 Gary V. Vaughan <gary@gnu.org>
2472 Since most of the build is handled from a single Makefile.am now,
2473 we can teach make about the dependencies between the m4 binary and
2474 the preopened modules it is built against:
2476 * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
2478 * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
2479 of the preopened modules have changed.
2481 2005-05-07 Gary V. Vaughan <gary@gnu.org>
2483 * configure.ac (gl_MODULES): Add mkstemp for machines that don't
2484 have a native implementation.
2486 2005-05-06 Gary V. Vaughan <gary@gnu.org>
2488 * src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are
2489 handled already by gnu/exit.h.
2491 * configure.ac (gl_MODULES): Add assert to support a
2492 --disable-assert configure time option for NDEBUG setting.
2494 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.
2495 * bootstrap (src_modules): Add version-etc-fsf.
2496 * src/main.c (version_etc_copyright): Removed.
2498 * ltdl/m4/m4-getopt.m4 (m4_GETOPT): Synch with gnulib/getopt.m4.
2500 2005-05-04 Gary V. Vaughan <gary@gnu.org>
2502 * src/m4.h (__CYGWIN__, WIN32): Canonicalise Windows and Cygwin
2504 * src/freeze.c (produce_frozen_state): Use \n line-endings even
2505 on Windows, so that the frozen file reader will work.
2506 Reported by Josef T. Burger <bolo@bolo.com>
2508 2005-05-04 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
2510 Forward port of a patch that allowed m4-1.4.2 to compile on
2513 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
2515 * src/m4.h: And include them as appropriate.
2516 * src/main.c, src/stackovf.h: Don't include signal.h literally;
2517 m4.h will include the correct file.
2519 2005-05-04 Gary V. Vaughan <gary@gnu.org>
2521 * m4/m4private.h: Make errno visible for the sources patched
2524 2005-05-04 Paul Eggert <eggert@twinsun.com>
2526 * src/main.c (print_program_name_CB): Preserve errno, since
2527 M4ERROR relies on this.
2528 * modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
2529 * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
2530 * m4/path.c (m4_path_search): Don't let "free" trash errno when
2533 * m4/output.c (m4_insert_file): Don't assume errno has a valid
2534 value simply because fread returns zero. This fixes a
2535 portability bug reported by Marion Hakanson in
2536 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
2538 2005-05-04 Santiago Vila <sanvila@debian.org>
2540 * tests/stackovf.test: Use tempfile if available.
2542 2005-05-04 Robert Bihlmeyer <robbe@orcus.priv.at> (tiny change)
2544 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=92629
2545 * m4/output.c (m4_insert_file): Do not mix buffered and
2546 unbuffered I/O, as this breaks on the Hurd.
2548 2005-05-04 Gary V. Vaughan <gary@gnu.org>
2550 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
2551 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
2552 and libtoolize does a better job of ltdl importing now too, so
2553 take advantage of that while updating the tree:
2555 * acm4, config: Moved from here...
2556 * ltdl/m4, ltdl/config: ...to here.
2557 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
2558 src/Makefile.am, tests/Makefile.am: Removed...
2559 * Makefile.am: ...and migrated to here, with adjustments to
2560 compensate for relative path differences.
2561 * commit: Adjust relative paths.
2562 * configure.ac: Adjust relative paths.
2563 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
2565 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
2566 the meanwhile, CVS HEAD libtool is needed.
2567 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
2568 stricly new enough, we also need a patch.
2569 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
2570 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
2571 (gl_MODULES): Don't list getopt and version-etc, as they don't
2573 * bootstrap: After running gnulib-tool to import the listed
2574 modules, fetch getopt and version-etc into src manually.
2575 (ltdldir): Change to ltdl.
2576 * src/main.c: Adjust for changes in version-etc API.
2577 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
2578 but works when the getopt module isn't to be included in the lib.
2579 * README: Add note about patching autoconf and automake to
2582 2005-05-02 Matt Kraai <kraai@debian.org> (tiny change)
2584 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=84416
2585 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
2586 empty file rather than to a nonexistent file. This closes a
2587 common security hole.
2588 * modules/m4.c (m4_maketemp): Implement the above, by using
2589 mkstemp rather than mktemp.
2591 2005-05-01 Gary V. Vaughan <gary@gnu.org>
2593 The FSF are moving offices today. Changed their contact address
2594 in all files from `59 Temple Place, Suite 330, MA 02111-1307' to
2595 `51 Franklin Street, Fifth Floor, MA 02110-1301'.
2597 2005-03-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
2599 * tests/Makefile (clean-local): Ignore testsuite cleanup
2602 2005-03-11 Per Bothner <per@bothner.com> (tiny change)
2604 * tests/Makefile (clean-local): Only run the testsuite cleanup
2605 if the testsuite has been generated.
2607 2005-02-11 Stepan Kasal <kasal@ucw.cz>
2609 * TODO: slight clarification of the example of qindir usage.
2611 2005-02-08 Gary V. Vaughan <gary@gnu.org>
2613 * TODO: Add qindir requirement, and defn bug.
2614 From Stepan Kasal <kasal@ucw.cz>
2616 2005-02-08 Stepan Kasal <kasal@ucw.cz>
2618 * TODO: Add ``execution stack'', fix a typo.
2619 * doc/m4.texinfo: Typos.
2621 2004-12-24 Eric Blake <ebb9@byu.net>
2623 * configure.ac (INCLUDE_STDBOOL_H): Account for gnulib's move
2624 to the gnu subdirectory.
2625 * acm4/m4-error.m4 (INCLUDE_ERROR_H): Likewise.
2626 * acm4/m4-obstack.m4 (INCLUDE_OBSTACK_H): Likewise.
2627 * acm4/m4-regex.m4 (INCLUDE_REGEX_H): Likewise.
2628 * m4/system_.h: Likewise, in non-configured includes.
2630 2004-10-14 Noah Misch <noah@cs.caltech.edu>,
2631 Gary V. Vaughan <gary@gnu.org>
2633 * m4/m4.c (m4_context_field_table, m4_context_opt_bit_table):
2634 Protect definitions from macro expansion under -DNDEBUG by
2635 parenthesising the expanded function names.
2636 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
2637 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
2638 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
2639 (m4_is_syntax_macro_escaped): Similarly protect function
2640 definitions from macro expansion under -DNDEBUG by #undefing the
2641 matching macro names before each definition. Also, move all the
2642 function definitions to the end of the file so that any
2643 invocations in the rest of the file pick up the fast macro
2645 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)
2646 (m4_set_debug_file, m4_set_trace_messages)
2647 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
2648 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
2649 (m4_set_max_debug_arg_length_opt): New fast macro versions of the
2650 option setter functions.
2652 2004-09-23 Gary V. Vaughan <gary@gnu.org>
2654 * po/POTFILES.in: Reflect move of gnulib files from gnulib/m4
2657 2004-09-23 Gary V. Vaughan <gary@gnu.org>
2659 * src/main.c: Include gnulib files from the correct directory.
2661 * gnulib/*: Don't store any of the gnulib files in arch, as they
2662 generate spurious changes.
2663 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
2664 gnulib macros now share our macro directory.
2665 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
2666 * bootstrap: Call gnulib-tool to import from the gnulib tree.
2667 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
2668 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
2669 the gettext macros from autopoint that overwrite the gnulib-tool
2670 imported versions. Import sources and Makefile.am into the `gnu'
2671 directory. Changed all callers.
2672 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
2673 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
2674 for imported modules.
2675 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
2676 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
2677 hardcoding the gnulib macros they wrap.
2679 2004-07-15 Gary V. Vaughan <gary@gnu.org>
2681 Latest CVS libtool can preload modules in libraries, including
2682 its own module loaders! Tweak m4 so that it doesn't try to treat
2683 libltdl's module loaders as m4 modules when freezing and on exit:
2685 * gnulib/acm4/*.m4: Don't store these files in arch since they
2686 generate spurious changes.
2687 * bootstrap: Simplify initial libtoolize call, since CVS
2688 libtoolize is smarter these days.
2689 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
2691 * m4/module.h (m4__module_exit): Missing declaration.
2692 * m4/m4private.h (m4__module_next): New function declaration.
2693 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
2694 encapsulation. Changed all callers.
2695 (m4__module_interface): New function to verify m4 loadable module
2697 (m4__module_init): Register the interface validator.
2698 (m4__module_exit): Only close my own modules.
2699 * modules/m4.c (unistd.h): Provide missing declaration.
2700 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
2701 (m4_expand_ranges): More missing declarations.
2702 * modules/modtest.c (export_test): Ditto.
2703 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
2704 * src/main.c (main): Bump copyright year.
2705 * tests/modules.at: Fix sed syntax error.
2708 2004-06-17 Gary V. Vaughan <gary@gnu.org>
2710 Tweaking to enable compilation with latest CVS libtool and
2711 libltdl. We can't just dump the library files directly into the
2712 m4 directory anymore now that libltdl is built from pieces itself:
2714 * bootstrap: Rewritten to use latest libtoolize sanely, and to
2715 set up libltdl subdirectory.
2716 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
2717 gnulib subdirectory's config.
2718 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
2719 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
2721 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
2722 configure.ac, so use AC_WITH_LTDL instead.
2723 * Makefile.am (SUBDIRS): Add libltdl.
2724 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
2726 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
2727 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
2728 (libm4_la_LIBADD): Add LIBLTDL.
2729 * m4/ltdl.c, m4/ltdl.h: Removed.
2730 * m4/m4module.h: Include canonical ltdl.h.
2733 2004-06-14 Gary V. Vaughan <gary@gnu.org>
2735 * gnulib/import: Now updates makefile fragments, and configure.ac.
2736 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
2737 * gnulib/m4/Makefile.am: include it.
2738 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
2739 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
2740 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
2741 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
2742 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
2743 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,
2744 gnulib/acm4/lib-ld.m4, gnulib/acm4/lib-prefix.m4,
2745 gnulib/acm4/error.m4, gnulib/acm4/po.m4, gnulib/acm4/regex.m4,
2746 gnulib/acm4/stdbool.m4, gnulib/acm4/stdint_h.m4,
2747 gnulib/acm4/uintmax_t.m4, gnulib/acm4/ulonglong.m4,
2748 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
2749 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
2750 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
2752 * gnulib/m4/getopt_int.h: New source file from latest gnulib
2754 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
2755 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,
2756 gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
2757 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
2758 Updated source files from latest gnulib.
2760 2004-02-29 Gary V. Vaughan <gary@gnu.org>
2762 * config/mailnotify: New file for mailing commit notifications,
2763 imported from cvs-utils.
2764 * commit: Updated from cvs-utils and tweaked for m4.
2766 2003-12-01 Gary V. Vaughan <gary@gnu.org>
2768 * config/mkstamp: Updated from CVS libtool.
2769 * configure.ac: Generate a gnu coding standards compliant version
2770 number, and use it for the banner.
2771 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
2772 mhen the TIMESTAMP changes in ChangeLog, but the file modification
2773 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
2774 contain the previous version number.
2775 * src/main.c: Make --version output conform to the GNU standard.
2777 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
2778 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
2779 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
2780 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
2781 time_la_SOURCES): ...so that these are defaulted correctly, and
2782 can be removed from this file.
2783 (AM_LDFLAGS): Add -module...
2784 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
2785 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
2786 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
2787 the individual settings can be removed.
2788 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
2789 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
2790 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
2791 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
2792 time_la_LIBADD): ...so that these are picked up as a deplib of
2793 libm4 and don't need to be set explicitly.
2795 2003-11-18 Gary V. Vaughan <gary@gnu.org>
2797 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
2798 from the standard build. It is too fragile.
2800 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
2801 CVS libtool after merging m4 changes across to libtool.
2803 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
2804 * m4/path.c (search_path_add): Ditto.
2806 2003-11-13 Gary V. Vaughan <gary@gnu.org>
2808 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
2809 libtool tags we don't use in configure. This reduces the size
2810 of the script from over 1Mb to under 700Kb.
2812 2003-11-13 Gary V. Vaughan <gary@gnu.org>
2814 The import script was not written properly, and the last gnulib
2815 import was incomplete. Fixed that problem, and reimport our
2816 gnulib dependencies, which picks up the address calculation
2817 overflow checks described by Paul below. Also tweak the clients
2818 of the gnulib xalloc module not to use deprecated macros:
2820 * gnulib/import: Recurse through module dependencies rather than
2821 naively descending only one level.
2822 * configure.ac: Add calls to gnulib's strnlen and extension module
2824 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
2826 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
2827 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
2828 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
2829 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
2831 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
2832 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
2833 place of `xcalloc (1, S)'.
2834 * m4/m4.c (m4_create): Likewise.
2835 * m4/m4private.h (m4_symbol_value_create): Likewise.
2836 * m4/symtab.c (symtab_fetch): Likewise.
2837 * m4/syntax.c (m4_syntax_create): Likewise.
2838 * src/freeze.c (reload_frozen_state): Likewise.
2839 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
2841 * m4/symtab.c (m4_symtab_create): Likewise.
2843 2003-11-13 Gary V. Vaughan <gary@gnu.org>
2845 * tests/module.at: Comment typo.
2847 2003-10-10 Gary V. Vaughan <gary@gnu.org>
2849 * tests/modules.at (modules: importing): Apply some lateral
2850 thinking, and use AT_CHECK to compare the output of a sed pass
2851 over stderr against the canonical strerror string.
2853 * tests/modules.at (modules: importing): Edit the generated stderr
2854 output to canonicalize strerror output, before a comparison.
2856 2003-10-10 Gary V. Vaughan <gary@gnu.org>
2858 Tru64UNIX perl is sloppy with namespace pollution. This patch is
2859 careful not to trip over the mess:
2861 * modules/perl.c: Some builds of perl install headers that contain
2862 `#define try __builtin_try'. Be sure to undefine that macro
2863 before `m4/hash.h' gets included, which uses the `try' symbol.
2864 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
2865 `false' before including `stdbool.h'.
2866 (DELETE): This symbol is not in m4's namespace, and is in any
2867 case only used internally...
2868 * m4/m4private.h (DELETE): ...so move it to here.

2873 Don't use XMALLOC and XCALLOC. Once we install the
2874 corresponding patch into gnulib, this will fix some
2875 address-calculation overflow bugs on hosts where calloc (A, B)
2876 returns garbage when A*B overflows.
2878 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
2879 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
2880 xmalloc, XCALLOC with xcalloc.
2881 * m4/m4.c (m4_create): Likewise.
2882 * m4/m4private.h (m4_symbol_value_create): Likewise.

2887 * src/main.c (main): Likewise.
2889 2003-10-07 Gary V. Vaughan <gary@gnu.org>
2891 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
2892 gnulib/acm4 directories for aclocal m4 macros.
2893 * gnulib/Makefile.am (EXTRA_DIST): Removed.
2894 (MAINTAINERCLEANFILES): Add Makefile.in.
2895 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
2897 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
2898 * gnulib/import: New file. Temporary script for updating gnulib
2899 imported files, until gnulib-tool is working.

2947 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
2948 guards ready for gnulib-tool to autoupdate on import.
2949 * config/debug.m4, config/gmp.m4, config/m4-error.m4,
2950 config/m4-gettext.m4, config/m4-obstack.m4, config/m4-regex.m4,

2953 acm4/m4-gettext.m4, acm4/m4-obstack.m4, acm4/m4-regex.m4,

2957 * m4/hash.c, m4/m4.c, m4/macro.c, m4/module.c, m4/output.c,
2958 m4/path.c, m4/symtab.c, m4/syntax, m4/system_.h, modules/m4.c,

2965 2003-09-16 Gary V. Vaughan <gary@gnu.org>
2967 * gnulib/m4/version-etc.c, gnulib/m4/version-etc.h: Import
2968 version-etc module from CVS gnulib.
2969 * po/POTFILES.in: Add gnulib/m4/version-etc.c.
2970 * src/Makefile.am: Build it.
2971 * src/main.c: Use it.
2973 * gnulib/m4/exit.h: Import exit module from CVS gnulib.
2974 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
2975 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
2978 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
2979 Gary V. Vaughan <gary@gnu.org>
2981 * bootstrap: Separate options.
2982 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
2983 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
2985 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
2986 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
2987 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
2988 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
2989 $(LTLIBINTL) for gettext support on cygwin.
2990 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
2991 have $(LTLIBINTL) from the preloaded module la files.
2992 * README: Remove the warning about using --disable-nls on Windows
2995 2003-09-15 Gary V. Vaughan <gary@gnu.org>
2997 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
2998 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
3001 2003-09-12 Gary V. Vaughan <gary@gnu.org>
3003 * doc/STYLE: Document the gnulib header naming conventions, and
3005 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
3006 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,
3007 gnulib/m4/gettext.h, gnulib/m4/obstack.h, gnulib/m4/regex.h
3009 * gnulib/m4/Makefile.am: Remove the rules to build these headers.
3011 * gnulib/m4/strtol.c, gnulib/config/strtol.m4: Import strtol
3012 module from CVS gnulib.
3013 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
3014 (gl_FUNC_STRTOL): In favour of the module macro.
3016 2003-09-12 Gary V. Vaughan <gary@gnu.org>
3018 Replace the getopt code with CVS gnulib getopt. The source files
3019 detect whether they are in a glibc environment and preprocess away
3020 all of the code if there is a system getopt, so we can compile
3021 them into the m4 executable unconditionally:
3023 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
3024 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
3025 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
3027 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
3029 * src/Makefile.am: Adjust.
3030 * src/main.c: Always include our shipped getopt.h.
3031 * po/POTFILES.in: Use new location of getopt.c.
3033 2003-09-12 Gary V. Vaughan <gary@gnu.org>
3035 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
3036 * config/Makefile.am: Removed. Automake 1.8 distributes the files
3037 in this directory automatically.
3038 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
3040 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
3042 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
3044 * modules/Makefile.am (pkglibexecdir): Set it here.
3045 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
3047 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
3048 Import regex module from CVS gnulib.
3049 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
3050 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
3051 do extra substitutions for Makefile.
3052 * configure.ac: Use it.
3053 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
3054 from regex_.h if necessary.
3055 * m4/system_.h: Include the correct version of regex.h.
3056 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
3058 * po/POTFILES.in: Use new location of regex.c.
3060 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
3061 realloc.c: automake distributes these files already.
3063 2003-09-12 Gary V. Vaughan <gary@gnu.org>
3065 Replace the xstrzdup code by importing the xstrndup module from
3066 CVS gnulib, along with its dependencies: strndup and strnlen:
3068 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
3069 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
3071 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
3072 gnulib/config/strndup.m4: Ditto wrt strndup.
3073 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
3075 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
3076 However, contrary to gnulib, we install xstrndup.h.
3077 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
3078 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
3079 is an artifact of the old m4 portability layer.
3080 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
3081 * m4/system_.h: Include xstrndup.h.
3082 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
3084 2003-09-11 Gary V. Vaughan <gary@gnu.org>
3086 Reimport the latest xalloc module from CVS gnulib, and adjust the
3087 m4 sources to take advantage of xalloc xfree. Also create a new
3088 macro DELETE with the same semantics as the old m4 XFREE macro,
3089 and carefully tweak callers:
3091 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
3093 * m4/utility.c (xfree): Removed. This function is now supplied by
3095 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
3096 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
3097 * m4/symtab.c (m4_symtab_create): Ditto.
3098 * m4/system_.h: Removed XFREE redefine.
3099 (DELETE): New macro with same functionality as the original m4
3100 XFREE macro, but based on xalloc.h now. Changed all callers.
3101 * src/main.c (main): Use XMALLOC macro.
3102 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
3104 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
3106 2003-09-10 Gary V. Vaughan <gary@gnu.org>
3108 Import the xalloc module from CVS gnulib, along with its
3109 dependencies: exitfail, malloc and realloc. We had different
3110 semantics for our XFREE and a function xfree() not supplied by
3111 gnulib, so also a bit of work to keep everything running
3114 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
3115 (gl_XALLOC): Use gnulib equivalents.
3116 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
3117 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
3118 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
3119 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
3121 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
3122 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
3123 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
3125 (pkgincdir): Removed. Use pkgincludedir instead.
3126 * m4/m4private.h (XFREE): xfree already checks for NULL.
3127 * m4/system_.h: Use xalloc module, and remove macros already
3128 supplied by xalloc.h.
3129 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
3130 moved the old definition from m4/xmalloc.c to here for now.
3132 2003-09-09 Gary V. Vaughan <gary@gnu.org>
3134 Import the error and progname modules from CVS gnulib. Our old
3135 error.c subsumed the functionality of both, so a little adjustment
3136 was required to accomodate the split in sources. Also added more
3137 wrapper macros to choose between a system installed error.h or our
3138 shipped gnulib error module:
3140 * m4/error.c, m4/error.h: Removed.
3141 * m4/Makefile.am: Adjust.
3142 (pkgincdir): Removed. Use pkgincludedir instead.
3143 * m4/module.h, src/main.c: Don't include `m4/error.h'.
3144 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
3146 * gnulib/m4/progname.c: Imported from CVS gnulib.
3147 * gnulib/m4/progname.h: Ditto.
3148 * src/main.c: Adjust to use progname module.
3149 * gnulib/m4/error.c: Imported from CVS gnulib.
3150 * gnulib/m4/error_.h: Ditto.
3151 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
3152 if appropriate, and link a local error.h if the system version is
3154 (libgnu_la_SOURCES) Add progname module sources.
3155 * gnulib/config/error.m4: Imported from CVS gnulib.
3156 * gnulib/config/strerror_r.m4: Ditto.
3157 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
3158 to have ERROR_H for Makefile substitutions and tell system.h
3159 whether the system error.h should be used, or a locally installed
3161 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
3163 2003-09-09 Gary V. Vaughan <gary@gnu.org>
3165 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
3166 s/gettext_.h/gettext.h/.
3168 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
3169 automake have been fixed.
3171 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
3172 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
3173 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
3174 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
3176 2003-09-09 Gary V. Vaughan <gary@gnu.org>
3178 The gnulib obstack module requires the gnulib gettext module for
3179 systems that do not have GNU gettext installed. Because we use
3180 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
3181 that directory incase it clashes with the system gettext.h. This
3182 delta uses gettext_.h and extra rules in the Makefile to make a
3183 link to gettext.h when needed:
3185 * Makefile.am (auxdir): Removed. No longer used.
3186 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
3187 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
3189 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
3190 Makefile based build.
3191 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
3192 of the macros are kept.
3193 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
3194 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
3195 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
3196 distributes these automatically.
3197 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
3198 warning from automake-1.7a.
3199 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
3200 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
3202 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
3203 wrt. m4_FUNC_OBSTACK.
3204 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
3205 wrt. m4_sys_STACKOVF.
3206 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
3207 wrt. _m4_LIB_GMP, m4_LIB_GMP.
3208 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
3209 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
3211 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
3212 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
3213 gettext.h link on deficient systems.
3214 (pkginc_HEADERS): Mention $(GETTEXT_H).
3215 (EXTRA_HEADERS): Mention gettext.h.
3216 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
3217 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
3218 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
3219 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
3220 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
3221 gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
3222 gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
3223 gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
3224 gnulib/config/po.m4, gnulib/config/progtest.m4,
3225 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
3226 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
3228 2003-09-05 Gary V. Vaughan <gary@gnu.org>
3230 We can't mirror the gnulib directory structure here, since we need
3231 to be able to eg. `#include <m4/obstack.h>' from our source files,
3232 which is much easier if the local obstack.h is created in a
3233 directory named m4. Rather than trying to symlink everything into
3234 the m4 directory, now we build a libtool convenience library from
3235 the sources we get from gnulib and link that with libm4.la:
3237 * gnulib/config/extensions.m4: Imported from CVS gnulib.

3240 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
3241 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
3242 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
3243 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
3244 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
3245 * m4/Makefile.am: Adjust.
3246 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
3247 macros we redistribute.
3248 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
3249 library among others.
3250 (GNULIB_SRCS, GNULIB_MACROS): Removed.
3251 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
3252 * config/m4-obstack.m4: Adjust.
3253 * po/POTFILES.in: Adjust.
3254 * configure.ac: Reformatting. Call newly imported gnulib macros.
3255 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
3256 bogus calls of `#include "m4.h"'.
3257 * Makefile.am: INCLUDES has been deprecated in favour of
3259 * m4/Makefile.am: Ditto.
3260 * modules/Makefile.am: Ditto.

3263 2003-09-05 Gary V. Vaughan <gary@gnu.org>
3265 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
3267 2003-09-04 Gary V. Vaughan <gary@gnu.org>
3269 Migrate the obstack support into the gnulib directories for easy
3270 synchronisation with upstream files in gnulib:
3272 * config/gnu-obstack.m4: Moved from here...
3273 * config/m4-obstack.m4: ...to here.
3274 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
3275 * m4/obstack.c, m4/obstack_.h: Moved from here...
3276 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
3277 * po/POTFILES.in: Adjust.
3278 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
3279 * m4/Makefile.am: Add a whole new section to link the obstack
3280 sources from the gnulib tree if necessary.
3281 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
3283 * config/m4-obstack.m4: Rewrite as a wrapper for
3284 gnulib/m4/obstack.m4.
3286 2003-09-04 Gary V. Vaughan <gary@gnu.org>
3288 GNU M4 currently builds with a number of files adapted from
3289 upstream sources. Recently the gnulib project on savannah.gnu.org
3290 has pulled together a great many of these externally maintained
3291 files. This delta is the beginnings of isolating those files
3292 maintained in gnulib to make it easy to synchronise M4 with the
3293 upstream files prior to releases.
3295 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
3297 (SUBDIRS): Added new gnulib subdirectory.
3298 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
3299 * config/stdbool.m4: Moved from here...
3300 * gnulib/m4/stdbool.m4: ...to here.
3301 * m4/stdbool_.h: Moved from here...
3302 * gnulib/lib/stdbool_.h: ...to here.
3303 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
3305 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
3306 code to work with new stdbool_.h location.
3307 (gnulib_srcdir): New.
3309 2003-09-04 Gary V. Vaughan <gary@gnu.org>
3311 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
3312 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
3314 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
3315 (EXTRA_DIST): Use it.
3317 * bootstrap: CVS autoreconf leaves file droppings. Remove
3318 aclocal.m4t incase autoreconf doesn't.
3320 2003-08-29 Gary V. Vaughan <gary@gnu.org>
3322 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
3323 the other gnulib imports, renamed to m4/obstack_.h.
3324 * m4/obstack.c: Updated from CVS gnulib.
3325 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
3326 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
3327 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
3328 about vpath already, and $top_srcdir upsets CVS Automake, so the
3329 $top_srcdir reference was removed.
3331 * m4/system-h.in: For consistency with the gnulib imports, renamed
3333 * m4/Makefile (EXTRA_HEADERS): Adjust.
3334 * configure.ac (AC_CONFIG_FILES): Adjust.
3336 * m4/stdbool_.h: New file from gnulib for systems without their
3338 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
3339 * config/stdbool.m4: New file. Macros from gnulib for same.
3340 * configure.ac: Use it.

3395 ac_default_headers is an autoconf internal variable.
3396 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
3397 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.

3403 2003-08-15 Gary V. Vaughan <gary@gnu.org>
3405 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
3407 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
3408 possible or faking one with a typedef. Changed all callers.
3410 2003-08-15 Gary V. Vaughan <gary@gnu.org>
3412 Still cleaning up the users' module API, by taking out the stuff
3413 that isn't used by any existing modules, and moving specialised
3414 functions out of libm4 and into the module they are used by.
3416 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
3417 * m4/utility.c (m4_skip_space): ...to here the home of its only
3418 use, made static and renamed to `skip_space'. Changed all
3420 * m4/m4module.h (m4_expand_ranges): Removed prototype.
3421 * m4/utility.c (m4_expand_ranges): Moved definition from here...
3422 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
3424 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
3426 * modules/gnu.c (builtin_syntax): Import and use in this
3427 builtin implementation.
3428 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
3430 * m4/macro.c (trace_flush): Except here where the macro is now
3432 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
3433 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
3435 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
3436 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
3438 2003-08-14 Gary V. Vaughan <gary@gnu.org>
3440 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
3441 compiler based AC_CHECK_HEADER that was introduced in
3443 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
3444 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
3445 * configure.ac: Use renamed M4_AC_LIB_GMP.
3447 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
3448 macro that requires arguments! This stops the shell's bad
3449 substitution error at configure time.
3451 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
3452 variables to the testsuite shell. Set the value of USE_GMP so
3453 that the gmp test will run!
3454 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
3456 2003-08-11 Gary V. Vaughan <gary@gnu.org>
3458 Libltdl already has an excellent mechanism for accessing C symbols
3459 in modules. Lets use that! Remove all the exporting cruft and
3460 just use lt_dlsym in conjunction with a few conventions to
3461 simplify module writers' jobs. Also removed the table address
3462 caching code and otherwise simplified the module loader quite a
3463 bit. To access exported symbols in other modules, first the
3464 exporting module must name the symbols <modname>_LTX_<symname>,
3465 and the importing module must define a function type called
3466 <symname>_func. The importer then adds
3467 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
3468 that wishes to call out to the exported functions. Care must be
3469 taken that <symname> is non-NULL in the importing module incase
3470 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
3471 definition was in the importers source. Study
3472 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
3473 m4_module_import will attempt to automatically load a module
3474 required for symbol access if it is not loaded already.
3476 * TODO: Removed the items fixed in this delta.
3477 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
3479 * m4/ltdl.h (lt_dlhandle_find): Declare it.
3480 * m4/module.c (m4_module_unload): Use it.
3481 * src/freeze.c (reload_frozen_state): Ditto.
3482 * m4/m4module.h (m4_export): Deleted. Removed all references.
3483 (M4_MODULE_IMPORT): New user convenience macro for importing
3484 arbitrary symbols from other modules.
3485 * m4/module.c (m4_module_import): New function to service
3486 M4_MODULE_IMPORT macro.
3487 (module_data): Removed. Looking up the tables on demand with
3488 lt_dlsym, rather than caching their addresses here simplifies the
3490 (m4_get_module_builtin_table, m4_get_module_macro_table):
3491 Removed. Changed all callers.
3492 (set_module_macro_table, set_module_builtin_table): Renamed to
3493 install_macro_table and install_builtin_table respectively, and
3494 simplified now that the cache is no more.
3495 * modules/gnu.c (builtin_symbols): Use this new mechanism to
3496 import m4_dump_symbols from the m4 module.
3497 (builtin_esyscmd): Likewise for m4_set_sysval and
3499 * modules/m4.c (m4_export_table): Removed. Functions are
3500 addressed with the new mechanism which doesn't need this.
3501 (m4_set_sysval): New exported accessor function to prevent
3502 problems with variable access on inferior architectures.
3503 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
3504 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
3505 that we can have some type safety.
3506 * modules/modtest.c (export_test): C level exported function for
3507 testing the new import mechanism.
3508 * modules/import.c: New file for the import end of the test.
3509 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
3510 * tests/modules.at: New test cases for intermodule symbol
3513 2003-08-07 Gary V. Vaughan <gary@gnu.org>
3515 * m4/m4module.c (m4_string): Moved from here...
3516 * m4/m4private.c (m4_string): ...to here.
3518 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
3520 2003-07-29 Gary V. Vaughan <gary@gnu.org>
3522 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
3523 already available to module writers through
3524 m4_{get,set}_nesting_limit_opt(), so moved from here...
3525 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
3526 (m4_create): Use it.
3528 2003-07-28 Gary V. Vaughan <gary@gnu.org>
3530 Aside from auditing path.c for m4module.h api obfuscation, this
3531 delta introduces the concept of private struct members in opaque
3532 data types to GNU m4: See the STYLE file for details.
3534 * TODO: Remind ourselves that a rewrite of path.c is needed.
3535 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
3537 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
3538 here and renamed. These type definitions are for internal api use
3539 only. Changed all callers.
3540 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
3542 * m4/path.c (search_path_env_init, search_path_add): ...to here
3543 and renamed. These calls were never used outside this file.
3544 Changed all callers.
3545 (dirpath): Moved functionality of this static declaration...
3546 * m4/m4private.h (struct m4): ...to this new internal only
3547 search_path field. Changed all callers.
3548 (m4__get_search_path): Added new internal api accessor.
3549 * m4/path.c (m4_search_path_info_new): Removed. Not used.
3550 (m4_include_init): Removed...
3551 * m4/m4.c (m4_create): ...because the new m4 field is now
3553 (m4_delete): Recycle search_path memory.
3554 * src/main.c (main): Don't call m4_include_init now that it's
3556 * doc/STYLE: Document convention for private fields in opaque
3559 2003-07-24 Gary V. Vaughan <gary@gnu.org>
3561 Sometimes exporting the address of a symbol from a module isn't
3562 enough for other modules to call that symbol correctly. If
3563 custom data types are used for function parameters, they need to
3564 be known to the caller. This change introduces the concept of
3565 $(prefix)/include/modules/$(modulename).h to declare those
3566 structures. Also we move m4_dump_symbols from libm4 to the m4
3567 module to show this concept in action.
3569 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
3570 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
3571 exporting data structures from modules/m4.c.
3572 * modules/m4.c, modules/gnu.c: Include it.
3573 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
3574 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
3576 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
3578 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
3579 ...to here, with slight renaming.
3580 (m4_export_table): Prototype and add m4_dump_symbols.
3581 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
3582 definition of m4_dump_symbols.
3583 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
3584 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
3586 2003-07-24 Gary V. Vaughan <gary@gnu.org>
3588 Create an export table in modules/m4.c in readiness for beefing up
3589 the module loader to track module exports and imports.
3591 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
3592 * m4/debug.c (m4_debug_flush_files): Moved...
3593 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
3594 * modules/gnu.c (builtin_esysval): Use it.
3595 * m4/m4module.h (m4_export): New type for declaring module symbols
3597 * modules/m4.c (m4_export_table): List symbols exported from this
3598 module for use by other modules.
3600 2003-07-24 Gary V. Vaughan <gary@gnu.org>
3602 An experiment: There is loads of code in libm4 which should be in
3603 the m4 module, but is also used by another module. Just because
3604 some linkers won't cope with calls across dynamic runtime loaded
3605 objects I initially left the code in libm4. It will tidy the
3606 module api immensely if this code moves to the right place, I just
3607 need to remember to invent a suitable calling mechanism at some
3608 point. For now, only modules that are statically linked and
3609 preloaded will get this treatment, so the only platforms that will
3610 break are those that require all symbols to be resolved at link
3613 * TODO: Reminder that what I am doing could reduce portability
3614 unless I do something more robust later.
3615 * m4/m4module.h (m4_sysval): No longer exported from libm4.
3616 * m4/utility.c (m4_sysval): No longer declared in libm4.
3617 * modules/Makefile.am: Reformatting.
3618 * modules/m4.c (m4_sysval): Declare it at place of use.
3619 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
3621 2003-07-23 Gary V. Vaughan <gary@gnu.org>
3623 * m4/m4module.h: Reformatting and rearranging lines a bit.
3624 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
3626 (m4_call_macro, m4_expand_input): Renamed...
3627 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
3629 (m4_expansion_level, m4_process_macro): Moved...
3630 * m4/macro.c (expansion_level, process_macro): ...to here, and
3633 * m4/m4module.h (program_name): Not used by modules at all, so
3635 * src/main.c (program_name): ...to here.
3636 (print_program_name): Renamed...
3637 (print_program_name_CB): ...to conform to the STYLE guide.
3639 2003-07-23 Gary V. Vaughan <gary@gnu.org>
3641 More refactoring of the m4module.h API. Replace #defines with an
3642 enum, and move non-public functions out of the public API.
3644 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
3646 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
3647 * m4/debug.c (m4_debug, trace): Moved...
3648 * m4/m4private.h (struct m4): ...to fields of this struct.
3649 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
3651 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
3652 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
3653 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
3654 * m4/m4module.h (m4_context_field_table): Add entries for new
3655 debug_file and trace_messages fields.
3656 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
3657 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
3658 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
3659 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
3660 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
3661 (m4_is_debug_bit): New macro to simplfy checks against the debug
3663 (m4_trace_format, m4_trace_header, m4_trace_flush)
3664 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
3666 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
3667 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
3668 * m4/macro.c (trace_format, trace_header, trace_flush)
3669 (trace_prepre, trace_pre, trace_post): ...to these newly static
3670 functions, since they are only ever used from this file. Changed
3673 2003-07-17 Gary V. Vaughan <gary@gnu.org>
3675 Change the macros for checking syntax so that matching against
3676 multiple possible syntax classes can be done with a single
3677 comparison some of the time. The various classes are now bits of
3678 an int that can be checked with bitwise logic operators.
3680 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
3681 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
3682 (M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)
3683 (M4_SYNTAX_ASSIGN, M4_SYNTAX_ALPHA, M4_SYNTAX_NUM)
3684 (M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)

3690 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
3691 Replace all calls with invocations of these...
3692 (m4_is_syntax, m4_has_syntax): ...New macros.
3693 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
3694 is no longer required with new macros. Changed all callers.
3696 2003-07-15 Gary V. Vaughan <gary@gnu.org>

3709 Gary V. Vaughan <gary@gnu.org>
3711 Conform to POSIX if the POSIXLY_CORRECT environment is set.
3712 --traditional `define' now smashes all the definitions.
3714 * NEWS: Explain this.

3717 POSIX are disabled if POSIXLY_CORRECT is set.
3718 (Incompatibilities): Remove.
3719 (Define, Other Incompat): Explain difference
3720 between GNU and POSIX behavior of define, pushdef, popdef.

3754 (Epatsubst and Patsubst): Typo.
3757 2003-06-26 Gary V. Vaughan <gary@gnu.org>
3759 Move the global variables that pertain to syntax to a new `struct
3760 m4_syntax_table', and then add one of these to `struct m4'. The
3761 ripple effect through the code to both change formerly global
3762 references, and make sure a suitable context is available in
3763 lexical scope is disproportionately large compared to the size of
3764 the change proper. This change is a large part of decoupling
3765 syntax.c from the rest of the code that uses it.
3767 * m4/m4private.h (struct m4): Add a syntax field.
3768 * m4/m4.c (m4_create): Initialise it,
3769 (m4_delete): Recycle it.
3770 (m4_get_symtab): Remove hand coded version...
3771 (m4_get_symbol_table): ...and generate this with cpp. Changed all
3773 * m4/m4module.h (m4_context_field_table): Add an extra field so we
3774 can generate m4_get_symbol_table. Add a new row for
3775 m4_get_syntax_table.
3776 (M4SYNTAX): Syntactic sugar for module writers.
3777 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
3778 (m4_syntax_table): New home for syntax related formerly global
3780 * m4/m4private.h (struct m4_syntax_table): Define it.
3781 * m4/input.c (m4_input_init): Initialisation of these formerly
3782 global variables moved...
3783 * m4/syntax.c (m4_syntax_create): ...to here.
3784 * m4/input.c (m4_input_exit): And similarly, recycling of the
3785 memory used by those values moved...
3786 * m4/syntax.c (m4_syntax_delete): ...to here.
3787 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
3788 Moved to m4/m4private.h.
3789 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
3790 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
3791 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
3792 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
3793 objects. Changed all callers that used to directly access the
3795 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
3796 Removed and incorporated into m4_syntax_table structure.
3797 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
3798 * m4/syntax.c (m4_set_syntax): Now returns an error status,
3799 instead of requiring a `struct m4' to generate its own errors.
3800 Changed all callers.
3801 * src/main.c (main): Now that the syntax table is initialised as
3802 part of m4_create, we have to manually wipe the syntax entries if
3803 we are about to read a frozen file.
3805 2003-06-26 Gary V. Vaughan <gary@gnu.org>
3807 * doc/STYLE: Added notes on callback naming schemes.
3809 * m4/module.c (m4_set_module_macro_table)
3810 (m4_set_module_builtin_table): Declarations weren't changed when
3811 definitions were renamed on 2003-06-19.
3813 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
3814 neither used nor particularly appropriate since it exposes the
3815 internal workings of the hash module. I haven't yet decided
3816 whether to remove it entirely.
3818 2003-06-20 Gary V. Vaughan <gary@gnu.org>
3820 Two related changes, and a huge knockon effect throughout the
3821 source: Moved the option variables out of global space and into
3822 `struct m4'; made `m4_symtab' a real datatype, so that its api
3823 is not marred passing `struct m4' around just so it can decide
3824 whether to keep traced symbol names or not. Added setters and
3825 getters for the formerly global option variables, and obviously
3826 changed a vast number of functions to take a `struct m4' and use
3827 the getter funcs to find option values.
3829 * m4/utility.c (interactive, sync_output, debug_level)
3830 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
3831 (max_debug_argument_length, warning_status, nesting_limit)
3832 (discard_comments): Removed.
3833 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
3834 (debug_level, max_debug_argument_length, prefix_all_builtins)
3835 (suppress_warnings, discard_comments, interactive, sync_output):
3836 Removed from here...
3837 * m4/m4private.h (struct m4): ...and equivalent fields added to
3839 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
3840 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
3841 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
3842 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
3843 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
3844 macros for the new fields.
3845 * m4/m4module.h (m4_context_field_table)
3846 (m4_context_opt_bit_table): Helper macros used to generate
3847 prototypes, setters and getters for new option fields
3849 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
3850 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
3851 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
3852 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
3853 (m4_get_interactive_opt, m4_get_sync_output_opt)
3854 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
3855 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
3856 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
3857 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
3858 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
3859 setter and getter functions generated by cpp from
3860 m4_context_field_table and m4_context_opt_bit_table, exported as
3861 part of the module api. Changed all callers.
3862 * m4/symtab (struct m4_symtab): Used as the concrete type for
3864 (m4_symtab_create): Allocate and initialise a new struct.
3865 (m4_symtab_apply): New function that works like m4_hash_apply, but
3866 with different callbacks specific to symbol tables. Changed all
3868 (symbol_destroy, arg_destroy, arg_copy): Renamed
3869 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
3870 they have unused parameters for a reason!
3871 (dump_symbol_CB): New callback to dump the contents of a single
3873 (symtob_dump): Rewritten in terms of dump_symbol_CB.
3874 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
3875 Changed all callers.
3876 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
3877 of the contained `m4_symtab' at the `no_gnu_extensions' field.
3878 Although I'm not convinced these semantics are correct, they are
3879 at least consistent with how things were before this delta. Also
3880 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
3882 2003-06-19 Gary V. Vaughan <gary@gnu.org>
3884 Tie down the interface to libm4 some more. Make more structures
3885 opaque to modules by moving them to m4private.h, and writing
3886 setters and getters. To win back the speed penalty for doing this
3887 also wrote macroized versions that do know about structure layout
3888 in m4private.h and #include that file into modules when NDEBUG is
3889 defined at compile time. There are still some accessor macros in
3890 m4private.h that need to go, but that is not necessary to clean
3893 * m4/m4module.h (m4_symbol_type): Moved...
3894 * m4/m4private.h (m4__symbol_type): ...to here.
3895 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
3896 (m4_set_symbol_traced, m4_set_symbol_name_traced)
3897 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
3898 (m4_get_symbol_func, m4_symbol_value_create)
3899 (m4_symbol_value_delete, m4_set_symbol_value_text)
3900 (m4_set_symbol_value_func): New exported api to symbols.
3901 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
3902 and m4_is_symbol_value_func.
3903 * m4/m4module.h: Prototype these guys.
3904 * m4/module.c (m4_set_module_macro_table)
3905 (m4_set_module_builtin_table): Make these static, there is no
3906 reason to pollute the api with them.
3907 * m4/m4private.h: Reformatting.
3908 (m4_get_symtab): Only define when NDEBUG is defined.
3909 (m4_get_symbol_value, m4_get_symbol_traced)
3910 (m4_set_symbol_traced, m4_set_symbol_name_traced)
3911 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
3912 (m4_get_symbol_func, m4_symbol_value_create)
3913 (m4_symbol_value_delete, m4_set_symbol_value_text)
3914 (m4_set_symbol_value_func): Macro implementations of the new
3915 functions when NDEBUG is defined.
3916 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
3917 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
3918 Superceded by the above. All callers changed.
3919 (M4ARG): Removed. This is no longer different to the
3920 m4/m4module.h definition.
3921 * modules/gnu.c, modules/m4.c: Only include m4private.h when
3922 NDEBUG is defined. That way we exercise the same (albeit slower)
3923 api that external modules must use.
3925 2003-06-18 Gary V. Vaughan <gary@gnu.org>
3927 Renamed some of the types and their accessors to make more sense.
3928 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
3929 has a stack of SYMBOL_VALUEs.
3931 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
3932 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
3933 m4_get_symbol_value_type, m4_get_symbol_value_text,
3934 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
3935 Changed all callers.
3936 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
3937 (m4_get_token_type): Renamed
3938 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
3939 to the internal api.
3940 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
3942 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
3943 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
3944 (m4__token_type): Moved here from m4module.h.
3945 (m4__next_token): Renamed from m4_next_token.
3946 * m4/symtab.c: Removed some of the parameterised macro support
3947 functions for modularisation later.
3948 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
3949 m4_hash_dup to perform a true deep copy of the SRC.
3950 (arg_copy): Callback for m4_symbol_value_copy.
3951 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
3952 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
3953 m4_get_symbol_value_func. Changed all callers.
3955 2003-06-18 Gary V. Vaughan <gary@gnu.org>
3957 Tidy up style of hash.[ch] in accordance with doc/STYLE.
3959 * m4/hash.c: Internal symbol renaming and formatting.
3960 (m4_hash_dup): New function to facilitate deep copies of hash
3962 (m4_hash_apply_func): Returns a void* now, which is a richer type
3963 for returning exceptions (NULL means keep going).
3964 (m4_hash_apply): Ditto.
3965 * m4/hash.h: Declare exported symbols with an explicit extern.
3968 2003-06-17 Gary V. Vaughan <gary@gnu.org>
3970 Still refactoring furiously. This delta represents a change in
3971 semantics to symtab.c. Instead of building temporary m4_tokens
3972 in the caller, and copying fields in the methods, we now create
3973 the actual m4_token for hashing in the caller so the methods just
3974 slot them in directly. Also, this means that we don't lookup a
3975 symbol and get back an allocated but VOID token to copy fields
3976 into, we create the token we want to push and pass that to
3977 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
3978 a few other small changes to stop knowledge of the implementation
3979 of symtab.c leaking out into other files.
3981 * m4/macro.c (expand_argument): Comment typo corrected.
3982 * m4/symtab.c (symtab_fetch): New function to fetch the address of
3984 (m4_symbol_pushdef): Take an extra value parameter and use this
3985 directly as the new top of the value stack. All callers changed
3986 to build a token and pass responsibility for memory in, rather
3987 than copying as we used to.
3988 (m4_symbol_define): Also use the new value parameter directly as a
3989 replacement for the top of the value stack. All callers changed
3990 to build a token as above.
3991 (m4_set_symbol_traced): New function to set the traced bit on the
3992 named symbol, creating it if necessary.
3993 (symbol_popval): The guts of the old m4_symbol_popdef.
3994 (m4_symbol_popdef): Use it.
3995 * m4/builtin.c (m4_symbol_set_token): Removed,
3996 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
3998 * m4/module.c (m4_set_module_builtin_table)
3999 (m4_set_module_macro_table): ...with these more orthogonal
4001 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
4002 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
4004 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
4005 (m4_arg_signature_parse): Moved...
4006 * m4/symtab.c: ...to here.
4007 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
4008 screw something up. Moved...
4009 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
4010 actually does a proper deep copy of source to dest.
4012 2003-06-16 Gary V. Vaughan <gary@gnu.org>
4014 Further refactoring to stabilise the module API. Renaming some
4015 functions for orthogonality, and judicious definition migration to
4016 move things out of the set of exported symbols.
4018 * doc/STYLE: New file. Notes on coding style.
4019 * m4/m4module.c: Updated bitrotted docucomment at the top of the
4021 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
4022 m4_get_module_name, m4_get_module_builtin_table,
4023 m4_get_module_macro_table which are verb phrases. Changed all
4025 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
4027 * m4/module.c (m4_set_module_builtin_table)
4028 (m4_set_module_macro_table): ...here, and renamed. Changed all
4030 * m4/m4module.c (m4_module_data): This...
4031 * m4/m4private.c (struct m4_module_data): ...and this...
4032 * m4/module.c (module_data) ...consolidated here and no longer
4033 exported. Changed all callers.
4035 2003-06-16 Gary V. Vaughan <gary@gnu.org>
4037 Begin work on lifting the curse of the global variables. To start
4038 with create a `struct m4' context container, and replace
4039 `m4__symtab' with `context->symtab' throughout. This means
4040 initialising a context container in main, and adjusting many
4041 functions between main and the module entry points so that the
4042 container gets passed through. It would have been nice to
4043 defer this until after 1.5, but it has a major effect on the
4044 user's module writing ABI, so it needs to be addressed now - at
4045 least in the areas that impact the ABI. An interrelated change
4046 in the symtab API removes the dependency on a global symbol table,
4047 and instead focuses on a passed table (from the context
4050 * TODO: Reminders for finishing context functionality.
4051 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
4052 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
4053 global variables and eventually allow m4 to be reentrant.
4054 * m4/m4private.h (m4): Define the new structure here...
4055 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
4056 don't carry the overhead of a function call.
4057 * m4/m4module.h: Prototype extern functions from m4/m4.c.
4058 (m4): Declare type for new struct m4 objects.
4059 (M4SYMTAB): User macro to ease finding the symbol table for the
4060 current context for module developers.
4061 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
4063 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
4064 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
4065 (m4_call_macro, m4_dump_symbols, m4_expand_input)
4066 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
4067 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
4068 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
4069 m4* context parameter. Changed definitions and all callers.
4070 (m4_symtab): Alias for m4_hash to decouple the
4071 m4_symtab api from m4_hash.
4072 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
4074 (m4_symtab_create): New function to return an initialised
4076 (m4_symtab_delete): New function to delete an m4_symtab's memory.
4077 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
4078 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
4079 instead of simply using the global m4__symtab. Changed
4080 definitions and all callers.
4081 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
4082 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
4083 * src/main.c (main): Create a context and use that instead of the
4084 former global m4__symtab.
4086 2003-06-13 Gary V. Vaughan <gary@gnu.org>
4088 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
4089 to the callback. Callbacks should not need to hardcode the
4090 hashtable they are working from, nor should we have to waste the
4091 userdata parameter to pass the table in.
4092 * m4/hash.h (m4_hash_apply_func): Require the initial table
4094 * m4/symtab.c (symtab_destroy): Use the passed table instead
4095 of hardcoding m4__symtab.
4096 (m4_symbol_popdef): Don't use the userdata parameter to pass the
4097 table to arg_destroy.
4098 (arg_destroy): Use the hash parameter, ignore userdata.
4099 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
4101 (traceon, traceoff): Call set_trace with the extra initial
4104 2003-06-13 Gary V. Vaughan <gary@gnu.org>
4106 More refactoring to stabilise the module api, this time for
4107 symtab.c. Additionally, start to pay attention to function names
4108 that don't contain a verb like they should.
4110 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
4111 wrapper for m4_hash_apply to decouple the symtab module from the
4113 (m4_symbol_builtin, m4_symbol_macro): Renamed to
4114 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
4116 (m4_symbol_delete): Create a macro version to save a function
4118 (m4_token_t, m4_data_t): These violate the POSIX reserved
4119 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
4121 (m4_token_type): Renamed to m4_token_get_type.
4122 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
4123 (m4_symtab_exit): Removed from the exported module
4125 * m4/m4private.h (m4__symtab, m4__symtab_init)
4126 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
4127 renamed and added to the internal api. Changed all callers.
4128 (m4_symtab_apply): A faster macro version of the function for
4129 users of the internal api.
4130 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
4131 symbol_destroy and arg_destroy.
4132 (symtab_debug): Added a prototype.
4133 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
4134 so that callers in this file get the faster macro versions from
4137 2003-06-12 Gary V. Vaughan <gary@gnu.org>
4139 Refactoring modules to rationalise the API into an external
4140 documented (eventually!) API for use by modules in the `m4_'
4141 namespace declared in m4/m4module.h, an internal API between the
4142 source files we ship (including our shipped modules) in the `m4__'
4143 namespace declared in m4/m4private.h and making the rest as
4144 cohesive as possible with liberal use of the `static' keyword.
4145 This change represents an audit to m4/module.c along these
4148 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
4149 Removed. No longer used.
4150 (m4_module_close): Removed prototypes.
4151 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
4152 from the exported module api...
4153 * m4/m4private.h (m4__module_init, m4__module_open)
4154 (m4__module_exit): ...and renamed and added to the internal api.
4155 Changed all callers.
4156 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
4157 Centralised definitions after renaming...
4158 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
4159 (M4_FINISH_SYMBOL): ...and removing from here.
4160 (m4_module_dlerror, m4_module_remove, m4_module_close)
4161 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
4162 module_remove, module_close and caller_id.
4163 (MODULE_SELF_NAME): New macro to make reporting self errors
4165 (m4_module_load, module_close, module_remove): Use it.
4166 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
4168 * src/main.c (main): Use it.
4170 2003-06-12 Gary V. Vaughan <gary@gnu.org>
4172 * README: Remove references to --enable-changeword, which has been
4173 removed from the code.
4175 2003-06-11 Gary V. Vaughan <gary@gnu.org>
4177 Getting rid of the annoying bug with configure --enable-debug,
4178 which spewed -e: command not found errors. This was an interaction
4179 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
4180 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
4181 branch-1-5) to get the full fix.
4183 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
4184 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
4185 and then use the probed value of $SED.
4186 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
4187 this, it messes up the AC_REQUIRE stack.
4189 2003-06-10 Gary V. Vaughan <gary@gnu.org>
4191 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
4192 the destroy callback.
4193 (m4_arg_destroy): Use the hash address to free the hash node key
4196 2003-06-06 Gary V. Vaughan <gary@gnu.org>
4198 First cut at formal parameters in macros.
4200 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
4201 * m4/xstrzdup.c: New file.
4202 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
4203 associative array of parameter names to details.
4204 (m4_symbol_token): Capture macro names with parameter lists.
4205 (m4_arg_signature_parse): And build an associative array to hang
4206 from the symbol structure to map names to details.
4207 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
4208 m4_hash_resize idiom. Now that we potentially add a little hash
4209 table to many of the entries in the symbol table, added an extra
4210 arg to set the initial size. Changed all callers.
4211 (m4_hash_apply): New function that is basically a generalised
4213 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
4214 all callers to call m4_hash_apply instead.
4215 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
4216 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
4217 m4_arg_signature association that might be attached to the symbol,
4218 * m4/hash.h (m4_hash_apply_func): Replacement type for...
4219 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
4220 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
4222 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
4223 (M4_IS_IDENT): Detect characters that can be safely used in
4225 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
4226 * m4/macro.c: Corrected grammar in some comments. Use `token'
4227 rather than `td' for m4_token variables.
4228 (m4_process_macro): If we find a dollar followed by some
4229 M4_IS_IDENT characters, replace that with the contents of the argv
4230 entry with offset stored in the m4_token_arg associated with the
4231 collected identifier.
4233 2003-06-05 Gary V. Vaughan <gary@gnu.org>
4235 Begin preparations for supporting formal parameters in m4 macros.
4237 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
4238 the details of a formal parameter.
4239 (m4_token): Add an arg_signature member to hold a hash table for
4240 looking up formal parameters.
4241 * m4/input.c: Update more bitrotted comments.
4242 (m4_push_builtin): Initialise arg_signature member.
4243 (init_builtin_token): Copy arg_signature member.
4244 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
4245 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
4247 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
4248 (m4_macro_pushdef, m4_macro_define): ...these, And...
4249 (m4_symbol_token): ...wrapped around this new function, which
4250 vastly simplifies the arguments required by the functions it
4252 Changed all callers.
4254 2003-06-05 Gary V. Vaughan <gary@gnu.org>
4256 * m4/macro.c: Format changes.
4258 2003-06-04 Gary V. Vaughan <gary@gnu.org>
4260 * m4/input.c: Updated various bitrotted comments.
4261 (m4_push_builtin): Just pass the whole m4_token, rather than
4262 extracting all the fields in the caller. This also allows us to
4263 check the token type for consistency.
4264 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
4265 Renamed to builtin_funcs, builtin_peek, builtin_read,
4266 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
4267 the code. Changed all callers.
4268 (struct input_block): Similarly renamed u_m member to u_b, and
4269 changed all callers.
4270 (m4_next_token): Use bzero to initialise the data fields.
4271 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
4273 2003-05-29 Gary V. Vaughan <gary@gnu.org>
4275 These changes were necessary to get m4 to build on my iBook
4276 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
4277 (GCC) 3.1 20020420 (prerelease)":
4279 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
4280 inclusion of module loader headers.
4281 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
4282 * m4/Makefile.am: Ditto.
4283 (libm4_la_LIBADD): Added $(LTLIBINTL).
4284 * m4/utility.c (program_name): Removed declaration in favour of
4285 the one already in error.c!
4286 * m4/m4module.h (program_name): Define to program_invocation_name
4287 when using GNU C library. Use an explicit extern declaration.
4288 (interactive, sync_output, debug_level, hash_table_size)
4289 (no_gnu_extensions, prefix_all_builtins, max_debug_argument_length)
4290 (suppress_warnings, warning_status, nesting_limit, discard_comments)

4296 (m4_expansion_level, m4_expand_ranges, m4_expand_input)
4297 (m4_call_macro, m4_process_macro, m4_syntax_table, m4_current_file)
4298 (m4_current_line, m4_current_diversion, m4_output_current_line):
4299 Don't rely on default, use an explicit extern.
4300 * m4/error.h (error, error_at_line, error_print_progname)
4301 (error_message_count, error_one_per_line): Ditto.
4302 * m4/ltdl.c: Update from CVS libtool.
4304 * commit: Update from CVS cvs-utils.
4306 2002-11-04 gettextize <bug-gnu-gettext@gnu.org>
4308 * po/Makefile.in.in: Upgrade to gettext-0.11.5.
4309 * po/boldquot.sed: New file, from gettext-0.11.5.

4317 2002-11-04 Akim Demaille <akim@epita.fr>
4319 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
4321 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
4323 2002-11-04 Akim Demaille <akim@epita.fr>
4325 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
4327 2002-11-04 Akim Demaille <akim@epita.fr>
4329 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
4330 used as `external', and Libtool 1.4.3.
4332 (LTLIBOBJS): Don't play with it.
4334 * Makefile.am (SUBDIRS): Remove intl.
4335 (ACLOCAL_AMFLAGS): Add -I config.
4336 (EXTRA_DIST): Add config/config.rpath.
4339 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
4341 2002-05-29 Gary V. Vaughan <gary@gnu.org>
4343 Preparations for refactoring syntax tables to allow reverse
4344 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
4345 speed of normal lookups in an array of unsigned short.
4347 * m4/input.c (single_quotes, single_comments, use_macro_escape):
4349 * m4/m4private.h (m4__single_quotes, m4__single_comments,
4350 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
4351 is for internal symbols which unavoidably pollute the global
4352 namespace, but are not published APIs.
4353 Adjusted all callers.
4354 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
4355 m4_set_comment, m4_set_syntax, set_syntax_internal,
4356 unset_syntax_attribute): Moved from this file...
4357 * m4/syntax.c: New. ...to this file.
4358 Also added an m4_syntax_exit stub for orthogonality.
4359 * src/main.c (main): Use it.
4360 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
4361 * m4/m4module.h: Reformatting. New prototypes.
4363 2002-05-29 Gary V. Vaughan <gary@gnu.org>
4365 * bootstrap (aclocal_apiversion): The aclocal apiversion is
4366 distinct from the automake release number (in that the apiversion
4367 apparently has no micro-version-component).
4368 (aclocal_apilibdir): Use it.
4370 2002-05-28 Gary V. Vaughan <gary@gnu.org>
4372 * m4/hash.c (m4_hash_resize): New function.
4373 * m4/hash.h: Add prototype.
4374 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
4375 benchmarking to find a good value for, say, autoconf. This is
4376 already a little quicker than before for me.
4378 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
4379 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
4381 * m4/hash.h: Adjust prototypes.
4383 2002-01-22 Akim Demaille <akim@epita.fr>
4385 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
4387 * tests/Makefile.am (package.m4): New.
4388 * tests/atlocal.in: Adjust to CVS Autotest.
4389 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
4390 * configure.ac: LIBOBJ is a forbidden string.
4391 Simplify AM_INIT_AUTOMAKE invocation.
4392 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
4395 2002-01-21 gettextize <bug-gnu-utils@gnu.org>
4397 * po/Makefile.in.in: Upgrade to gettext-0.10.40.
4399 2001-10-19 Akim Demaille <akim@epita.fr>
4401 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
4403 2001-10-19 Akim Demaille <akim@epita.fr>
4405 * m4/input.c (m4_next_token): Display where was opened what is
4408 2001-10-19 Akim Demaille <akim@epita.fr>
4410 * m4/macro.c (expand_argument): Display where was opened what is
4413 2001-10-18 Akim Demaille <akim@epita.fr>
4415 * m4/input.c, modules/m4.c: Formatting changes.
4417 2001-10-17 Gary V. Vaughan <gary@gnu.org>
4419 * bootstrap: s/configure.in/configure.ac/
4421 2001-10-16 Gary V. Vaughan <gary@gnu.org>
4423 * m4/symtab.c (m4_symbol_destroy): This function calls
4424 m4_symbol_popdef, which recycles a symbols memory when the last
4425 definition is popped. Since we were passing the address of the
4426 symbol name found in the symbol table, and it was being removed
4427 partway through m4_symbol_destroy() we were referencing freed
4428 memory for the balance of the function. Now we take a copy of the
4429 symbol name tring and use that as a key into the symbol
4430 table... that way if the original symbol name is freed, the copy
4433 2001-10-13 Akim Demaille <akim@epita.fr>
4435 * m4/ltdl.c: Update.
4437 2001-10-13 Akim Demaille <akim@epita.fr>
4439 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
4440 Don't gettextize internal error messages.
4442 2001-10-13 Akim Demaille <akim@epita.fr>
4444 * tests/macros.at (Arity and defn): New failing test.
4445 (Arity, defn, and freeze): New.
4447 Fix `Arity and defn'.
4449 * m4/input.c (m4_push_macro): Don't forget the arity.
4450 * modules/m4.c (defn): Likewise.
4452 2001-10-13 Akim Demaille <akim@epita.fr>
4454 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
4456 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
4457 (Propagation of traceon, Propagation of --trace): this new file.
4459 2001-10-13 Akim Demaille <akim@epita.fr>
4461 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
4462 interface instead of (name, argc...).
4463 Upon failure, specify which argument was guilty.
4466 2001-10-13 Akim Demaille <akim@epita.fr>
4468 * modules/evalparse.c: Save translators' time: don't translate
4469 internal error messages.
4470 (m4_evaluate): Simplify/normalize error messages.
4471 * doc/m4.texinfo (Eval): Adjust.
4473 2001-10-13 Akim Demaille <akim@epita.fr>
4475 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
4476 where no checking is needed.
4477 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
4478 interface instead of (name, argc...).
4480 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
4483 2001-10-13 Akim Demaille <akim@epita.fr>
4485 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
4486 exclude the builtin name from the count.
4487 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
4488 calling ifelse with a single argument is valid.
4489 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
4490 with 1 and 2 args, mostly to strengthen the test suite.
4492 2001-10-13 Akim Demaille <akim@epita.fr>
4494 * m4/output.c (m4_make_diversion, m4_insert_file)
4495 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
4497 2001-10-12 Gary V. Vaughan <gary@gnu.org>
4499 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
4500 since we call these things builtins in the rest of the code!
4502 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
4504 2001-10-12 Gary V. Vaughan <gary@gnu.org>
4506 Rather than forcing each builtin definition to manage its own
4507 argument range checking, tabulate the maxima and minima for all
4508 builtins in each module. This forces us to consider what the
4509 valid ranges for each builtin should be, and moves the checking
4510 code out of each builtin implementation and into the builtin
4511 caller infrastructure.
4513 * m4/m4module.h (struct m4_builtin): Add argument minima and
4515 * m4/m4private.h (struct m4_token): Reflect them here too.
4516 * m4/input.c (struct input_block): ...and here.
4517 (m4_token_copy): New function for token copying.
4518 (init_macro_token): Copy them from a token to the input stack.
4519 (m4_next_token): Don't forget to initialise them for text
4521 * m4/macro.c (expand_argument): Use m4_token_copy, and also
4522 check argument counts before calling the builtin handler.
4523 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
4524 (m4_symbol_macro): Likewise.
4525 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
4526 parameters. Updated all callers.
4527 (m4_builtin_define): Ditto.
4528 (m4_macro_pushdef, m4_macro_define): Ditto.
4529 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
4530 * modules/evalparse.c: Declare argument counts for defined
4531 builtins and remove explicit calls to m4_bad_argc().
4532 * modules/gnu.c: Ditto.
4533 * modules/load.c: Ditto.
4534 * modules/m4.c: Ditto.
4535 * modules/modtest.c: Ditto.
4536 * modules/mpeval.c: Ditto.
4537 * modules/perl.c: Ditto.
4538 * modules/shadow.c: Ditto.
4539 * modules/stdlib.c: Ditto.
4540 * modules/time.c: Ditto.
4543 2001-10-10 Gary V. Vaughan <gary@gnu.org>
4545 The trace semantics now attach the trace bit to a symbol name.
4546 For as long as a traceon(`foo') is active, calls to foo will be
4547 traced regardless of intervening undefines or module unloads.
4548 Fixed the flag propogation issues differently to the fixes
4549 reverted with the last attempt at nailing down trace:
4551 * m4/m4private.h: This file is not visible outside of the m4
4552 source tree, so I removed all the `M4_' and `m4_' prefixes to save
4553 on typing. Updated all clients.
4554 (m4_token): New typedef contains the fields that need to be passed
4555 around with the low level tokeniser.
4556 (m4_token_data): Removed.
4557 (m4_symbol): Now contains the traced flag again.
4558 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
4559 the trace bit set. This change is contained entirely within this
4560 module and doesn't leak out into the callers. Updated all
4562 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
4563 new fields in m4_token. Updated all clients.
4564 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
4565 that `groks_macro_args' and `blind_if_no_args' flags are retained
4566 when defn() results are passed around in m4 code. Updated all
4568 (m4_builtin_define): Ditto.
4569 (m4_macro_pushdef, m4_macro_define): Ditto.
4570 * m4/input.c (struct input_block): Add a flags field to facilitate
4572 (m4_push_macro): ...use it.
4573 (init_macro_token): Retrieve it.
4574 (m4_next_token): Initialise it.
4575 * m4/macro.c (expand_argument): Copy it.
4576 * m4/m4module.h: Adjust.
4577 * tests/builtins.at: Adjust the expected output of the trace
4578 tests to reflect the change in semantics.
4579 * tests/modules.at (modules: trace): Check that unloading a
4580 module which supplies a traced symbol definition doesn't lose te
4583 2001-10-07 Gary V. Vaughan <gary@gnu.org>
4585 * modules/gnu.c (m4_macro_table): Display the timetamp when
4586 expanding __m4_version__.
4588 * configure.ac (--with-modules): Forgot a comma in the
4589 AC_HELP_STRING parameter list.
4591 2001-10-05 Gary V. Vaughan <gary@gnu.org>
4593 * bootstrap: Remove aclocal.m4t when it is no longer required.
4595 2001-10-05 Akim Demaille <akim@epita.fr>
4597 * tests/Makefile.am: Adjust for gnuprog2.
4598 * tests/m4.in: There can be a leading path.
4599 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
4600 * tests/testsuite.at: Adjust to the most recent Autotest.
4601 (AT_CHECK_M4_FILTER): Fix and rename as...
4603 * tests/others.at: Use it.
4605 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
4606 variable in shell scripts, one uses `$'...
4608 2001-10-04 Gary V. Vaughan <gary@gnu.org>
4610 * configure.ac: `rm -f $m4_getopt_h' was lost.
4612 2001-10-04 Gary V. Vaughan <gary@gnu.org>
4614 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
4615 time. Define it for config.h in order to...
4616 * src/main.c (main): ...display the timestamp for --version.
4618 2001-10-04 Akim Demaille <akim@epita.fr>
4620 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
4621 previous builtins `regexp' and `patsubst'.
4622 (regexp, patsubst): Use them.
4623 (eregexp, epatsubst): New builtins.
4624 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
4625 (Epatsubst and Patsubst, Eregexp and Regexp): these.
4626 (Extensions): More info on REs.
4628 2001-10-04 Akim Demaille <akim@epita.fr>
4630 * modules/modtest.c (init_handler): Consistently output to stderr.
4631 (finish_handler): New.
4632 (test): The `if' is an `assert'.
4633 * tests/modules.at: Adjust.
4635 2001-10-04 Akim Demaille <akim@epita.fr>
4637 * m4/utility.c (m4_bad_argc): Detail the mismatches.
4639 2001-10-01 Akim Demaille <akim@epita.fr>
4641 * tests/generate.awk: Tag the tests with `documentation'.
4642 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
4643 Use the make the existing modtest tests more uniform, and complete
4644 the set of possibilities.
4646 2001-10-01 Akim Demaille <akim@epita.fr>
4648 * config/gmp.m4: Consult the user before using GMP: use
4650 * configure.ac: Adjust.
4651 * modules/gmp.c: No protection needed as the module is not built
4654 2001-10-01 Akim Demaille <akim@epita.fr>
4656 * tests/generate.awk: Remove debugging code.
4657 (fatal): Specify the current location.
4659 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
4660 * modules/gnu.c, modules/m4.c: Use M4ARG.
4662 2001-10-01 Akim Demaille <akim@epita.fr>
4664 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
4665 (m4_regexp_compile): New.
4666 (regexp, patsubst): Use it.
4668 2001-09-30 Gary V. Vaughan <gary@gnu.org>
4670 Reinstate the memory handling improvements from the patch I just
4671 reverted. Relevant ChangeLog entries repeated here:
4673 * m4/module.c (m4_module_remove): New function that holds the core
4674 of the old m4_module_unload.
4675 (m4_module_unload): Use it.
4676 (m4_module_unload_all): When we know the modules will never be
4677 used again (i.e. on exit), free up as much module memory as
4678 possible. There are still some artifacts from resident modules
4679 living inside ltdl.c, but everything else is freed.
4680 * m4/debug.c (m4_debug_exit): Free memory allocated in
4682 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
4683 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
4684 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
4685 * m4/m4module.h: Updated prototypes.
4686 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
4687 * m4/hash.h: Updated prototypes.
4688 * src/main.c (main): Use all these new functions to clean up as
4689 much memory as possible before exit.
4691 2001-09-30 Gary V. Vaughan <gary@gnu.org>
4693 Reverted my large patch for removing the old m4_symbol
4694 structure on 2001-09-20. We are still not happy about the way
4695 trace works in conjunction with defn and undefine, and leaving
4696 the reverted patch active prevents us from moving the traced
4697 bit from the definition back to the symbol.
4699 2001-09-30 Gary V. Vaughan <gary@gnu.org>
4701 * configure.in: Moved to...
4702 * configure.ac: ...here. Added a libtool like timestamped
4703 banner, and tidied up the libltdl cruft.
4704 * config/mkstamp: Script to extract a timestamp from ChangeLog.
4705 * modules/Makefile.am (INCLTDL): Removed. This is required
4706 only when libltdl is configured in a subdirectory.
4707 * src/Makefile.am: Ditto.
4708 (LIBADD_DL): No need to add this again, libtool already knows
4709 that libm4.la depends on it.
4710 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
4713 * TODO: stackovf.c is basically broken.
4714 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
4716 2001-09-28 Akim Demaille <akim@epita.fr>
4718 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
4720 2001-09-27 Akim Demaille <akim@epita.fr>
4722 * tests/m4.in: Don't use short options.
4723 Simplify the stderr signature normalization.
4725 2001-09-27 Akim Demaille <akim@epita.fr>
4727 tests/m4 shall be position independent.
4731 * tests/testsuite.at: No args to AT_INIT.
4732 * configure.in, tests/Makefile.am: Adjust.
4734 2001-09-22 Akim Demaille <akim@epita.fr>
4736 Autotest has changed again.
4738 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
4739 (package.m4): Remove.
4740 * configure.in: Adjust to LIBADD_GMP.
4742 2001-09-21 Gary V. Vaughan <gary@gnu.org>
4744 * config/gmp.m4 (AC_ARG_WITH): Removed.
4745 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
4746 (AC_LIB_GMP): When performing a test compile against libgmp,
4747 include the header gmp.h if possible, and link against -lgmp. If
4748 they both work define USE_GMP.
4749 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
4750 (mpeval_LTX_init_func): Complain on load that there was no libgmp
4753 2001-09-20 Gary V. Vaughan <gary@gnu.org>
4755 * m4/evalparse.c: Moved to...
4756 * modules/evalparse.c: ...here. This code is shared between
4757 modules/mpeval.c and modules/m4.c, so there is no need to pollute
4758 the libm4 API with its details. Moderately rewritten to interface
4759 into its clients more simply.
4760 * m4/eval.c: Deleted. Migrated functionality to...
4761 * modules/m4.c: ...here.
4762 (builtin_eval): Implemented in terms of the new interface style.
4763 * modules/mpeval.c (builtin_mpeval): Ditto.
4764 * m4/m4module.h: Removed references to the former m4/eval.c.
4765 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
4766 (EXTRA_libm4_la_SOURCES): Deleted.
4767 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
4768 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
4770 2001-09-20 Akim Demaille <akim@epita.fr>
4772 * config/gmp.m4 (AM_WITH_GMP): Rename as...
4774 By default, use gmp.
4776 * configure.in: Adjust.
4777 Use Automake conditionals for USE_GMP.
4778 Always compute sizeof (long long int).
4779 This was a bug BTW, as `eval' (not `mpeval') depends on it:
4780 before, it was used _only_ if mpeval was not activated.
4781 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
4782 (mpeval_la_LIBADD): New macros.
4783 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
4785 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
4786 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
4789 2001-09-20 Akim Demaille <akim@epita.fr>
4791 * tests/Makefile.am (package.m4): New.
4792 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
4794 2001-09-20 Gary V. Vaughan <gary@gnu.org>
4796 More cleanup. After the last patch, m4_symbol holds nothing but
4797 the head of a chain of m4_token_data. So I have removed the old
4798 m4_symbol, so that m4_token_data chains are stored directly in the
4799 value cell of a hash table node. But there's more... m4_symbol
4800 was a more natural name for the symbol value cell, and now that it
4801 is gone I have renamed the former m4_token_data structure to
4802 m4_symbol. This change turned out to be a pig to get right, since
4803 the original code didn't need to modify the value cell itself,
4804 since changing the chain happened inside the m4_symbol that used
4805 to be returned -- I had to pass the address of the value cell
4806 across various function calls, incase the head value changed. I
4807 also tightened up the memory management to help me find a nasty
4808 memory corruption bug that took me all night to track down...
4810 * m4/m4private.h (struct m4_symbol): Removed.
4811 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
4813 * m4/hash.c (m4_hash_iterator_value): Return the address of the
4814 value cell. Updated all callers.
4815 * m4/symtab.c: Took advantage of the simplification in the data
4816 structures to rewrite a lot of this file more simply. There is
4817 still some room for optimisation here, but we should tackle that
4818 systematically closer to the release.
4820 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
4821 revealed. This version is ahead of CVS libtool until I get chance
4822 to flush my changes.
4823 * m4/module.c (m4_module_remove): New function that holds the core
4824 of the old m4_module_unload.
4825 (m4_module_unload): Use it.
4826 (m4_module_unload_all): When we know the modules will never be
4827 used again (i.e. on exit), free up as much module memory as
4828 possible. There are still some artifacts from resident modules
4829 living inside ltdl.c, but everything else is freed.
4830 * m4/debug.c (m4_debug_exit): Free memory allocated in
4832 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
4833 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
4834 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
4835 * m4/m4module.h: Updated prototypes.
4836 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
4837 * m4/hash.h: Updated prototypes.
4838 * src/main.c (main): Use all these new functions to clean up as
4839 much memory as possible before exit.
4841 2001-09-18 Gary V. Vaughan <gary@gnu.org>
4843 The `traced' flag needs to be attached to the definition of a
4844 symbol rather than the current symbol containing the definition.
4845 Implementing this showed up some long standing post 1.4 bugs in
4846 flag propogation which I also fixed.
4848 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
4849 (struct m4_token_data): And add it back in here.
4850 * m4/input.c (init_macro_token): Propogate the traced flag
4852 * m4/macro.c (expand_argument): Ditto.
4853 * tests/builtins.at (trace2, trace3): New tests based on Akim's
4856 2001-09-08 Gary V. Vaughan <gary@gnu.org>
4858 * m4/m4private.h (struct m4_token_data): Simplified by removing
4859 the redundant `traced' flag, and one level of structure nesting.
4860 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
4861 * m4/input.c (init_macro_token): No need to initialise removed
4863 * m4/macro.c (expand_argument): No need to copy it either.
4864 * m4/utility.c (m4_token_data_func_traced): Or provide an access
4867 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
4868 dependant on multiple symbols with the same key, so preserving
4869 relative symbol order in each bucket during resizing is no longer
4870 required. The resize function is considerably faster as a result.
4872 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
4873 s/m4_symbol_insert/m4_symbol_define/g;
4874 s/m4_builtin_insert/m4_builtin_define/g;
4875 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
4877 2001-09-08 Gary V. Vaughan <gary@gnu.org>
4879 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
4880 commits, the m4_lookup_symbol dispatch function is split into
4881 specialised functions that must be called directly.
4883 * m4/m4module.h (m4_symbol_lookup_t): Removed.
4884 * m4/symtab.c (m4_lookup_symbol): Removed.
4885 (m4_symbol_builtin, m4_symbol_macro): New functions.
4886 * m4/builtin.c (m4_builtin_define): Split into...
4887 (m4_builtin_pushdef, m4_builtin_insert): ...these.
4888 (m4_macro_define): Split into...
4889 (m4_macro_pushdef, m4_macro_insert): ...these.
4890 * src/main.c (main): Set command line macros from `-D' parameters
4891 using `m4_macro_define'.
4893 2001-09-08 Gary V. Vaughan <gary@gnu.org>
4895 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
4896 this from m4_remove_table_reference_symbols().
4897 * m4/m4module.h, m4/module.c: Updated all references.
4899 2001-09-07 Akim Demaille <akim@epita.fr>
4901 * modules/stdlib.c, modules/times.c: Misc cleanups.
4903 2001-09-07 Akim Demaille <akim@epita.fr>
4905 * configure.in: We now need Autoconf 2.52e.
4906 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
4907 and `M4_SYMBOL_DELETE'.
4908 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
4909 * src/main.c (main): Adjust.
4911 2001-09-06 Gary V. Vaughan <gary@gnu.org>
4913 Fix the obstack.h problem once and for all! At configure time we
4914 can test for a system supplied obstack.h: depending on the
4915 result, we now generate system.h with an #include of the correct
4916 header. As a bonus, I've also added a --with-included-obstack,
4917 incase the user doesn't like the system obstack for some
4918 reason... and also we can test the shipped obstack on a system
4919 that has oe of its own. We also now need to be careful to add
4920 build directories to the include search path, since the generated
4921 system.h will be in the build tree.
4923 * configure.in (AC_CONFIG_FILES): Generate system.h from
4925 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
4926 include the system obstack header or the copy shipped with M4.
4927 Allow the user to override configure and force the build to use
4928 the shipped version.
4929 * m4/system-h.in: New file, template for...
4930 * m4/system.h: ...this. Now deleted.
4931 * m4/m4module.h: Include system.h before everything else.
4932 * src/freeze.c: Ditto.
4933 * m4/Makefile.am (dist-hook): Remove generated system.h.
4934 (INCLUDES): Check builddir for generated headers before checking
4936 * modules/Makefile.am (INCLUDES): Ditto.
4937 * src/Makefile.am (INCLUDES): Ditto.
4939 2001-09-05 Gary V. Vaughan <gary@gnu.org>
4941 * TODO: Remove the items that have been addressed already.
4943 2001-09-05 Akim Demaille <akim@epita.fr>
4945 * src/main.c (main): Standardize --version.
4947 2001-09-05 Akim Demaille <akim@epita.fr>
4949 * modules/format.c (format): Have a bigger `str'.
4951 2001-09-05 Akim Demaille <akim@epita.fr>
4953 Rationalize warnings, reporting the macro name as if it were a
4954 program name, and assertions.
4956 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
4958 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
4960 Use assert for internal errors.
4961 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
4963 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
4965 * tests/builtins.at (pushpop): Adjust.
4967 2001-09-05 Akim Demaille <akim@epita.fr>
4969 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
4972 2001-09-05 Akim Demaille <akim@epita.fr>
4974 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
4975 * m4/macro.c, m4/symtab.c: Adjust.
4977 2001-09-05 Akim Demaille <akim@epita.fr>
4979 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
4980 (m4_symbol_pop, m4_symbol_del): this.
4981 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
4982 (m4_symbol_popdef, m4_symbol_delete): New.
4983 (m4_lookup_symbol): Adjust.
4984 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
4986 2001-09-05 Akim Demaille <akim@epita.fr>
4988 * m4/m4module.h (m4_symbol_lookup): Rename as...
4989 (m4_symbol_lookup_t): this.
4991 2001-09-05 Akim Demaille <akim@epita.fr>
4993 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
4995 * m4/symtab.c (m4_lookup_symbol): Adjust.
4997 2001-09-03 Gary V. Vaughan <gary@gnu.org>
4999 Bootstrap will now work with Libtool 1.4.1 or higher:
5000 * bootstrap: Remove stale autom4te.cache files when
5002 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
5004 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
5005 libtool.m4 directly.
5006 Run libtoolize to refresh ltmain.sh.
5007 * config/ltmain.sh: Deleted.
5008 * acinclude.m4: Deleted.
5009 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
5011 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
5012 implementation for the cvs impaired libtool user.
5014 2001-09-03 Akim Demaille <akim@epita.fr>
5016 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
5018 Avoid using `default' in switch, as it hides useful compiler
5019 warnings when a case is forgotten.
5021 2001-09-03 Akim Demaille <akim@epita.fr>
5023 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
5024 is no such thing as `WITH_MODULES'.
5026 2001-09-03 Akim Demaille <akim@epita.fr>
5028 Improve the test suite's selfcontainedness.
5030 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
5031 (Include, Undivert): Tag the other input files.
5032 * tests/generate.awk: Catch `@comment file:'.
5033 `-I $src' is no longer needed.
5034 `next' is really like `return': the rest is skipped.
5035 Adjust to `input.m4'.
5036 (fatal): New function.
5037 * tests/foo, tests/incl.m4: Remove.
5039 2001-09-01 Gary V. Vaughan <gary@gnu.org>
5041 The shadowing mechanism and, infact, the whole symbol table
5042 implementation was creaking under the weight of the features piled
5043 on top of it. We now have a separate hash table module which will
5044 dynamically resize to keep symbol density withing good performace
5045 limits, and a new symtab module layered above it. Symbol lookups
5046 are now marginally more efficient (since the shadowed flag is no
5047 longer required) and symbol removal, such as on module unload, is
5048 considerably faster due to a reorganisation of the data structures
5051 * src/main.c (main): Don't mention `-H'.
5052 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
5055 * m4/hash.c: New generalised dynamic hash table data structure
5057 * m4/hash.h: Public interface.
5058 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
5059 (libm4_la_SOURCES): Add hash.c.
5060 * m4/symtab.c: More or less rewritten from scratch, within the
5061 bounds of the previous API.
5062 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
5063 call. Updated all callers.
5064 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
5065 declarations to reflect API changes.
5066 (M4INIT): Generate a declaration too, to avoid the warning with
5067 --enable-debug builds.
5070 * m4/utility.c (hash_table_size): Removed.
5071 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
5072 names, which are then looked up by builtin_dumpdef() as necessary.
5073 This implies a small speedup in builtin_symbols(), which discarded
5074 all of the symbol info under the old call.
5075 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
5076 shadowing is implicit in respect to the new data structures.
5077 symbol names are no longer duplicated here, they are stored in the
5078 key field of the hash table.
5079 Moved macro_args and blind_no_args...
5080 (m4_token_data): ...to here.
5081 m4/macro.c (expand_macro): Added a name argument since the symbol
5082 name is no longer copied into each struct m4_symbol. Modified all
5084 (collect_arguments): Ditto.
5085 * modules/m4.c (set_trace): Ditto.
5086 * modules/gnu.c (builtin_symbols): Updated.
5087 * src/freeze.c (produce_symbol_dump): Much improved in light of
5088 the improved symbol table layout.
5090 2001-09-01 Gary V. Vaughan <gary@gnu.org>
5092 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
5094 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
5095 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
5096 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
5097 SYMBOL_HANDLE): Ditto.
5098 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
5099 modules/gnu.c, modules/m4.c, src/freeze.c,
5100 src/main.c: Updated all references.
5102 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
5103 Automake 1.5 chokes on dynamic source file lists, Besides, it is
5104 already listed in m4_LDADD... how did that ever used to work?
5105 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
5107 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
5108 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
5110 * tests/m4: Don't call the m4 wrapper script with libtool, it
5111 works fine all by itself.
5113 2001-08-30 Gary V. Vaughan <gary@gnu.org>
5115 The experimental `changeword' feature never took off, and has
5116 no obvious advantages over `changesyntax' to compensate the
5117 enormous speed penalty it carries:
5118 * configure.in (ENABLE_CHANGEWORD): Removed.
5119 * m4/m4module.h (m4_set_word_regexp): Removed.
5120 * m4/m4private.h (m4_token_data): Removed original_text field.
5121 * m4/utility.c (m4_token_data_orig_text): Removed.
5122 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
5123 * m4/macro.c: Ditto.
5124 * src/main.c: Ditto.

5139 (ACLOCAL_MACROS): this.
5140 (list-standard-macros): Remove.
5143 2001-08-29 Gary V. Vaughan <gary@gnu.org>
5145 In an attempt to moderate my egomania...
5146 * tests/modules.at: Remove attributions.
5148 * tests/generate.awk: When making substitutions to "@&t@", either
5149 "&" or "\&" in the substitution string argument to gsub refer back
5150 to the matched text. "@\\&t@" seems to work though, Tests 43 and
5153 2001-08-29 Akim Demaille <akim@epita.fr>
5155 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)

5157 (sync-lines, trace, translit, undivert, wrap): Move to...
5158 * tests/builtins.at: this new file.
5159 * tests/others.at (Discard comments, import-environment): Move to...
5160 * tests/options.at: this new file.
5162 2001-08-29 Akim Demaille <akim@epita.fr>
5164 * tests/others.at (Freezing modules)
5165 (--module-directory: absolute path, modpath2, modpath3)
5166 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
5167 * tests/modules.at: here, new file.
5168 * tests/others.at, tests/generate.awk: Add a banner.
5169 * tests/testsuite.at: Adjust.
5170 (AT_CHECK_M4_FILTER): New, but unused.
5172 2001-08-29 Akim Demaille <akim@epita.fr>
5174 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
5176 * tests/others.at (wrap): Inline wrap.m4.
5177 (shadow): Inline shadow.m4.
5178 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
5179 * tests/m4: Simplify.
5181 2001-08-29 Akim Demaille <akim@epita.fr>
5183 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
5186 2001-08-29 Akim Demaille <akim@epita.fr>
5188 * tests/generate.awk (normalize): s/@__@/@&t@/.
5190 2001-08-28 Akim Demaille <akim@epita.fr>
5192 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.
5194 2001-08-28 Gary V. Vaughan <gary@gnu.org>
5196 * bootstrap (generate.awk): Generate test cases with new script.
5198 2001-08-27 Akim Demaille <akim@epita.fr>
5200 * tests/Makefile.am (installcheck-local): Don't use
5201 `dc_install_base' which is not visible here, but `exec_prefix'
5202 which is clearly the RT anyway.
5203 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
5204 related to testing a now installed m4.
5205 * tests/m4: Do it here.
5207 2001-08-27 Akim Demaille <akim@epita.fr>
5209 * tests/others.at (indir): Formatting change.
5211 2001-08-27 Akim Demaille <akim@epita.fr>
5213 * tests/Makefile.am (installcheck-local): New.
5214 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
5216 Prefer options over envvars.
5217 * src/main.c (main): First bug caught by the test suite (yeah!):
5218 --batch lacked a `break' which resulted in an accidental
5219 invocation of --discard-comments.
5221 2001-08-27 Akim Demaille <akim@epita.fr>
5223 * tests/others.at (capitalize, changeword, comments, ddivert)
5224 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
5225 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
5226 (sysv-args, trace, translit, undivert): Don't rely on files in
5227 examples/: AT_DATA them.
5229 2001-08-27 Akim Demaille <akim@epita.fr>
5231 Let the test suite use a wrapper around the not installed m4 to
5232 pretend it is (installed).
5234 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
5235 such a way that m4 does not process them.
5236 * configure.in: The package name seems to be `m4', not `M4'.
5238 * tests/atlocal.in (at_package, M4): Remove.
5239 * tests/testsuite.at, tests/others.at: Use m4, not $M4.
5241 2001-08-27 Akim Demaille <akim@epita.fr>
5243 * tests/Makefile.am (CLEANFILES): Remove.
5244 (DISTCLEANFILES, clean-local): New.

5249 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
5250 Don't use aclocal: it's written by hand.
5251 * aclocal.m4: m4_include all the files instead of being built by
5253 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
5254 until it reads the traces by itself.
5255 * configure.in: Require Autoconf 2.42c as we are now using
5256 AC_CONFIG_TESTDIR instead of AT_CONFIG.
5257 Catch unexpanded `jm_' macros.
5258 * config/atconfig.m4: Remove.
5259 * config/error.m4: new.
5260 * config/Makefile.am: Ship the files included by aclocal.m4.
5261 * tests/Makefile.am (TESTSUITE_SOURCES): Rename as...
5262 (TESTSUITE_AT): this, to please Automake.
5263 (TESTSUITE): This target uses autotest/autotest.m4, not
5264 autotest/general.m4.

5269 (dist_man_mans): this.
5271 2001-08-20 Gary V. Vaughan <gary@gnu.org>
5273 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
5274 Robert Collins, building on Cygwin no longer requires Windows
5275 import and export symbol decorations.
5276 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.
5277 * m4/error.h (M4_SCOPE) [cygwin*]: Ditto.

5290 2001-08-20 Gary V. Vaughan <gary@gnu.org>
5292 Ansify the source. Previously we had a mix, where my code was
5293 in a K&R compatible style, and the preexisting code was in ANSI
5294 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
5295 and now the code base is much cleaner.
5297 * m4/system.h: Remove M4_PARAMS macro and all users. Remove
5298 VOID macro and all users.
5299 * m4/m4module.h: Ansify function prototypes and headers.

5317 2001-08-20 Akim Demaille <akim@epita.fr>
5319 * config/atconfig.m4: s/EOF/ATEOF/, so that configure can be
5320 generated with stock 2.52.
5322 2001-08-20 Akim Demaille <akim@epita.fr>
5324 * config/atconfig.m4: New, until part of Autoconf per se.
5325 * configure.in (AT_CONFIG): Use it.
5327 * tests/mkconfig.sh, tests/atconfig.in, tests/defs: Remove.
5328 * tests/atlocal.in: New.

5331 * tests/others.at (changeword, gmp): Check the configuration
5332 variable against `yes'.
5333 * tests/testsuite.at (dnl): Allow it, as it's used all over the

5338 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
5339 * modules/m4.c (undivert): Disable the possibility of undiverting
5340 several files at once: it is not documented, it is inconsistent
5341 with the other macros, it can be straightforwardly mocked by
5342 several invocations, and most importantly, it prevents the
5343 possibility of other kinds of extension.
5344 Use `m4_numeric_arg'.
5346 2001-08-20 Akim Demaille <akim@epita.fr>
5348 * examples/include.m4: Typo.
5349 * tests/generate.awk: Really add it.
5350 * tests/Makefile.am: Adjust.
5351 * tests/others.at (Discard comments): It sure fails without `-c'.
5352 (include, undivert): Add -I examples/.
5354 2001-08-20 Akim Demaille <akim@epita.fr>
5356 Use sprintf, not ecft and friends since it is standard, portable,
5357 simplifies the code, and since the latter is even deprecated
5358 according to the GNU libc documentation.
5360 * modules/format.c: Drop evct support.
5362 2001-08-19 Gary V. Vaughan <gary@gnu.org>
5364 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Cleaned up. Don't test
5366 * configure.in: ...do it here instead.
5368 * c-boxes.el: Deleted.

5415 (generate.at): Install a temporary hack until the actual
5416 generate.awk is added to the repository.

5466 others.at no longer depends on other-tests/.

5472 (discard-comments, gmp, import-environment, modfreeze)

5504 2001-08-17 Akim Demaille <akim@epita.fr>
5506 Drop Autoconf 2.13 compatibility.
5508 * configure.in (changeword): No need to undefine it, as anyway if
5509 it's defined, M4sugar moved it as m4_changeword.
5510 And anyway, proper quotation is enough.
5511 (m4_pattern_allow): As it exists in 2.50, just use it.
5512 (AC_OUTPUT): Split in AC_CONFIG_FILES and AC_CONFIG_COMMANDS.

5519 (m4_errprint): Use fputs.
5520 * doc/m4.texinfo (Invoking m4) <--error-output>: errprint and
5521 dumpdef are not concerned.
5522 (Dumpdef, Errprint): Emphasize their insensitivity to
5524 * doc/Makefile.am: Add `TAGS' support.
5525 (MAINTAINERCLEANFILES): Remove texinfo.tex and mdate-sh which are
5527 * config/Makefile.am (MAINTAINERCLEANFILES): New.
5529 2001-08-17 Akim Demaille <akim@epita.fr>
5531 * modules/Makefile.am (ETAGS_ARGS): New.

5546 2001-08-16 Gary V. Vaughan <gary@gnu.org>
5548 m4_modules are no more, we use lt_dlhandles directly and let
5549 latest libltdl features manage the list of loaded modules.
5550 * acinclude.m4: Regenerated.
5551 * m4/ltdl.c: Updated from master copy.
5552 * m4/module.c: Reimplemented to take advantage of advances in
5554 * m4/builtin.c (m4_builtin_find_by_name): Traverse loaded module
5555 list with lt_dlhandle_next.
5556 (m4_builtin_find_by_func): Ditto.
5557 (m4_builtin_table_install): Use lt_dlhandle.
5558 (m4_macro_define): Ditto.
5559 (m4_macro_table_install): Ditto.
5560 m4/module.h: Prototype new module management API.
5561 (m4_modules): No longer required.
5562 (m4_module_init_t, m4_module_finish_t): POSIX namespace
5563 violations, renamed to...
5564 (m4_module_init_func, m4_module_finish_func): ...these,
5566 (M4INIT_HANDLER): Clean way to declare init functions in modules.
5567 (M4FINISH_HANDLER): And similarly for finish functions.
5568 * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER
5569 -- Add indirection to the CONC macro so that arguments are
5571 * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
5572 * modules/shadow.c (m4_init_module): Ditto.
5573 Due to new init function semantics, be careful to perform the
5574 initialisation only on first load.
5575 * modules/perl.c (m4_init_module): Ditto. And Ditto.
5576 (m4_finish_module): Replaced with M4FINISH_HANDLER.
5577 Due to new finish function semantics, be careful to perform the
5578 finalisation only on first load.
5579 * m4/m4private.h (m4_module): Removed in favour of...
5580 (m4_module_data): ...structure without all the wrapper fields.
5581 Instances of this new structure are stored associated lt_dlhandles
5582 with lt_dlcaller_data_set().
5583 * m4/builtin.c (m4_builtin_define): Takes a handle argument
5584 instead of the old module argument.
5585 (m4_builtin_table_install): Ditto.
5586 * modules/load.c (m4_resident_module): Removed. This is no
5587 longer implemented as a magic symbol...
5588 * modules/m4.c (m4_resident_module): Ditto.
5589 * modules/load.c (M4INIT_HANDLER): ...the module init function now
5590 uses the ltdl api to make the module resident.
5591 * modules/m4.c (M4INIT_HANDLER): Ditto.
5592 * modules/load.c (builtin_modules): Traverse the loaded module
5593 list with lt_dlhandle_next.
5594 (builtin_load): Much simplified in light of the reimplemented
5596 * src/freeze.c (produce_module_dump): Cleaned up and optimised in
5597 light of the m4/module.c rewrite.
5598 (produce_symbol_dump): Ditto.
5599 (reload_frozen_state): Ditto.
5600 * m4/list.c, m4/list.h: Files deleted. No longer required.

5602 (libm4_la_SOURCES): Delete list.c reference.
5603 * m4/m4private.h (m4_token_data): Add a handle field. This
5604 eliminates many of the searches to find the handle associated with
5605 various tokens that are passed between functions.
5606 (struct m4_symbol): Removed the module field. The
5607 module association does not belong with the symbol...
5608 * m4/input.c (struct m4_builtin): ...it belongs with the builtin
5609 that the module implementation code is from. Added a handle
5611 (m4_push_macro): Add a `handle' argument. Changed all callers.
5612 (init_macro_token): Set the `handle' field for the
5614 * m4/macro.c (expand_argument): Copy the new handle field during
5616 * modules/m4.c (macro_install): Use the new handle field to
5617 optimise the search for the correct builtin structure, and pass
5618 the handle details to m4_builtin_define.
5620 2001-08-15 Akim Demaille <akim@epita.fr>
5622 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Be sure `m4/' exists
5623 when creating `m4/obstack.h'.
5624 * tests/Makefile.am (TESTS_ENVIRONMENT): Pass top_srcdir and
5626 * tests/defs: Make them absolute.
5627 (CDPATH) Neutralize.
5628 * tests/gethem: Use them.
5630 2001-08-14 Gary V. Vaughan <gary@gnu.org>
5632 * config/ltmain.sh: Doh! Import again for a quoting fix that
5633 prevented any regression test from passing.
5635 * m4/m4module.h (obstack.h): Choose between installed version
5636 and shipped version based on configure tests.
5637 * src/freeze.c (obstack.h): Ditto.
5639 * acconfig.h: Removed. No longer required.
5641 * bootstrap: Rewritten to play nicely with Autoconf 2.5x.
5642 * configure.in (MY_NAME, MY_VERSION): Define these once, and feed
5643 them to AC_INIT and AM_INIT_AUTOMAKE.
5644 * Makefile.am (AUTOMAKE_OPTIONS): Remove `gnits' which would
5645 disallow MY_NAME and MY_VERSION arguments to AM_INIT_AUTOMAKE.
5646 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Don't choke on
5647 shell variable m4_cv_func_obstack_h.
5648 * tests/defs (M4): Be more careful about relative path to libtool
5649 script and m4 binary by using $srcdir.
5651 * src/main.c (main): Use lt_dlinsertsearchdir to prepend -M
5652 optargs to the existing libltdl search path.
5653 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.
5654 * m4/ltdl.c: Updated.
5656 * config/ltmain.sh: Ditto.
5658 2001-08-11 Gary V. Vaughan <gary@gnu.org>
5660 * src/main.c (main): Add `-b' (for `batch') mode switch to force
5661 interactive mode off.
5663 2001-08-10 Akim Demaille <akim@epita.fr>
5665 * configure.in: Require Autoconf 2.52.
5666 (AC_ARG_PROGRAM): Remove, handled by Automake.
5667 (m4_getopt): Rename as...
5668 (m4_getopt_h): this.
5669 Allow the tokens `m4_cv_*', `m4_top_srcdir', and `m4_getopt_h'.
5670 Undefine `changeword' only if defined.
5671 * config/gnu-obstack.m4: Require Autoconf 2.52.
5672 (M4_AC_FUNC_OBSTACK): Rename `m4_obstack' and `m4_obstack_h'.

5680 2001-08-09 Andreas Schwab <schwab@suse.de>
5682 * src/main.c (main): Fix improper uses of error (missing format
5685 2001-08-07 Akim Demaille <akim@epita.fr>
5687 Improve `make distcheck'.
5689 * configure.in: Be sure to be able to run `mkconfig.sh' when src
5691 * Makefile.am (dist-hook): Remove, as it is no longer needed.
5692 * doc/m4.texinfo (Include): Add missing blank.
5693 * m4/Makefile.am (EXTRA_DIST): Distribute gnu-obstack.h and
5696 2001-08-07 Akim Demaille <akim@epita.fr>

5721 interpreting the position of the decimal point correctly for
5724 2000-12-01 Gary V. Vaughan <gary@gnu.org>
5726 * TODO: Removed m4exit bug.
5727 * modules/load.c (m4_resident_module): Make this module resident.
5728 * module/m4.c (m4_resident_module): Ditto.
5729 * m4/modules.c (m4_module_load): Use new ltdl resident modules
5730 feature to mark modules as resident if they export
5731 `m4_resident_module' as TRUE.
5732 (m4_module_unload): Do not remove resident modules, and take care
5733 with symbol insertion and deletion with resident modules.
5734 * m4/ltdl.c, m4/ltdl.h: Update to latest unreleased versions to
5735 use resident modules feature.
5737 2000-11-30 Gary V. Vaughan <gary@gnu.org>
5739 * TODO: Updated. Removed some cruft that has since been fixed
5740 or implemented. Added some more entries.
5743 * modules/README: Updated.
5744 * doc/m4.texinfo: Updated.
5746 * modules/gnu.c (builtin_functions): Make indir orthogonal to
5747 builtin, in that each is recognised as a macro only with parameters
5748 (builtin_indir): Passing 0 arguments is now an error, as with
5751 * src/main.c (usage): Added missing description of `-c' option.
5753 2000-11-29 Gary V. Vaughan <gary@gnu.org>
5755 Consolidate the myriad of dispersed test scripts into the
5756 tests subdirectory. I think I now have all the file where I
5757 want them, so there shouldn't be anymore upheaval =)O|
5759 * tests/Makefile.am: Updated to run the new tests added below.

5798 Move the implementation of GMP support for the mpeval() builtin
5799 into a loadable module that depends on libgmp. mpeval() and
5800 eval() share a common parser, now in m4/evalparser.c; the code
5801 in m4/numb.c and m4/numb.h is now physically split between
5802 m4/eval.c (the eval() backend) and modules/mpeval.c (the
5803 mpeval() backend), rather than being differentiated by cpp
5804 macros and multiple inclusion. The mpeval module is always
5805 built but will generate an diagnostic if it is used from an
5806 installation that didn't link in the gmp library.
5807 * modules/Makefile.am: build and install the new mpeval module.
5808 * modules/mpeval.c: Now contains the former parts of m4/numb.c
5809 and m4/numb.h that are required for gmp support in mpeval().
5810 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
5811 * m4/evalmp.c: Removed.
5812 * m4/m4module.h: Removed conditional prototype for
5814 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
5815 and m4/numb.h that do not rely on gmp.
5816 * m4/evalparse.c: New file, contains the shared parts of the
5817 eval() and evalmp() parser implementations, and is no longer
5818 unencumbered by cpp magic to uncover the right parts.
5819 * m4/numb.h: Removed. It's former contents are split between
5820 m4/eval.c and modules/mpeval.c.
5823 * tests/other-tests/changeword.test: New test. Rudimentary
5824 testing of changeword builtin runs only if --wnable-changeword
5825 was used at configure time.
5826 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
5827 alternation correctly. Split into two expressions to compensate.
5828 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
5829 * modules/Makefile.am: Build changeword module.
5830 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
5831 only when --enable-changeword was passed to configure.
5832 (builtin_changeword): If --enable-changeword was not used, then
5833 report that changeword() builtin has no support in m4 binary.
5835 2000-11-28 Gary V. Vaughan <gary@gnu.org>
5837 * src/main.c (main): Fixed a particularly nasty bug is
5838 user_search_path setting -- the -M flag processing must be
5839 extremely careful with search path ordering, or else the default
5840 installed module directory (possibly containing modules from a
5841 previous release) is placed earlier in the search path than any -M
5842 arguments (which are relied upon to load uninstalled modules with
5843 most of the tests in the regresion suite).
5845 * modules/load.c (builtin_load): Nasty hack to prevent adding
5846 symbols to symtab again if a module is loaded more than once.
5847 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
5849 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
5850 possible NULL pointer dereference.
5852 * m4/module.c (m4_module_find_by_modname): Renamed from
5853 m4_module_modname_find. Fixed all references.
5854 (m4_module_find_by_builtin): New function.
5856 * modules/modfreeze.test: load the `load' module with each
5858 * src/freeze.c (produce_frozen_state): Simplified in light of
5859 module field in m4_symbol. Allow a third argument for text macros
5860 to name the originating module.
5861 (reload_frozen_state): ditto.
5862 * m4/m4module.h: Fixup prototypes.
5863 * m4/builtin.h (m4_builtin_define): Add a module argument so
5864 that symbols can be registered against the defining module.
5865 (m4_macro_define): ditto.
5866 * m4/m4private.h (m4_symbol): Make the module field const to save
5867 on casting in the rest of the code.
5868 (SYMBOL_MODULE): New macro.
5870 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
5871 symbol reference maintenance bugs when removing a symbol from the
5874 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
5876 2000-11-27 Gary V. Vaughan <gary@gnu.org>
5878 * configure.in (m4_cv_func_obstack): A better check for whether
5879 libc has an obstack implementation.
5880 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
5882 * configure.in (--with-modules): Changed semantics. This
5883 option is now used to list modules to be preopened.
5884 * src/m4.h: #include "ltdl.h" unconditionally.
5885 * src/main.c: Removed all dependencies on WITH_MODULES.
5886 * src/freeze.c: ditto.
5887 * modules/Makefile.am: ditto.
5888 * m4/m4.c (builtin_m4exit): ditto.
5889 * modules/modpath1.test: ditto.
5890 * modules/modpath2.test: ditto.
5891 * modules/modpath3.test: ditto.
5892 * modules/modpath4.test: ditto.
5893 * modules/modtest.test: ditto.
5894 * modules/shadow.test: ditto.
5895 * modules/unload.test: ditto.
5897 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
5898 comes up on demand in LTLIBOBJS now.
5899 * configure.in (getopt_long): Creating and relying on a link for
5900 getopt.h on hosts with no getopt_long() of thier own works
5901 correctly now. This is necessary so that callers of getopt_long()
5902 can simply `#include <getopt.h>': the naive way of doing this
5903 would end up using our own getopt.h and the installed
5904 getopt_long(), which is asking for trouble!
5905 (obstack_init): A similar argument applies to obstack.h and
5908 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
5909 On Solaris-2.5 (at least) the native dlopen implementation
5910 gets confused about m4.o when looking for module "m4". This
5911 version always looks for .la an .$lib_ext suffixed names first
5912 to work around the problem. Sigh.
5914 * po/POTFILES.in: Take account of these file movements.
5915 * src/Makefile.am (m4_SOURCES): removed eval.c.
5916 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
5917 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
5918 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
5919 * modules/m4.c (builtin_eval): Use m4_evaluate().
5920 * m4/eval.c: Moved here from src/eval.c to facilitate
5921 implementation of eval() builtin as part of the `m4' loadable
5923 (m4_evaluate): renamed from evaluate for namespace cleanliness.
5924 * m4/numb.c: Moved here from src/numb.c, since it is #included
5925 into eval.c at compile time.
5926 * m4/m4module.h (m4_evaluate): Added prototype.
5927 * src/m4.h (evaluate): Removed prototype.
5929 2000-11-25 Gary V. Vaughan <gary@gnu.org>
5931 * modules/perl.c (builtin_perleval): Use PL_na for
5932 compatibility with perl-5.6.
5934 * src/main.c (main): It is now safe to
5935 ``m4_module_install("m4")'', without tripping over the m4
5937 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
5938 versions having fixed the insidious module search order bug.
5940 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
5941 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
5943 * configure.in: Figure out whether to use the installed
5944 getopt.h or the supplied one.
5945 * src/Makefile.am: ditto.
5947 * po/POTFILES.in: List files in their new positions.
5949 * config/ltmain.sh: This needs to be checked in to match the
5950 libtool macros copied to acinclude.m4 (until a released
5951 libtool copes with m4's needs).
5952 * bootstrap: Run gettextize.
5954 2000-11-24 Gary V. Vaughan <gary@gnu.org>
5956 * AUTHORS: Added my details.
5959 * bootstrap: temporary update until released libtool catches up.
5961 * All files: Use new GNU GPL copyright blurb with current contact
5964 * configure.in (LTLIBOBJS): Use canonical code for calculation of
5967 * config: renamed acm4 directory to config to be more like
5968 other autoconfiscated packages.
5970 * configure.in (M4_AC_CHECK_DEBUGGING): Use it.
5971 * config/debug.m4: New file implementing configure macros to add
5972 suitable debug flags to the compiler invocation.
5974 * modules/load.c: New file implementing the ``load'' and
5975 ``unload'' builtins.
5976 * tests/get-them: Set the module search directory to the modules
5977 build directory in generated tests.
5978 * modules/shadow.test: ditto.
5979 * modules/modtest.test: ditto.
5980 * modules/modpath1.test: ditto.

5985 * modules/modfreeze.test: ditto.
5986 * modules/unload.test: ditto.
5988 * modules/changeword.c: New file implementing the ``changeword''
5989 builtin as a loadable module.
5990 * modules/mpeval.c: New file implementing the ``mpeval'' builtin

6284 src dir and immediately after libm4 is built for confidence that
6285 it doesn't rely on the src directory.
6286 (SUBDIRS): Moved doc dir to the end since helptoman.pl and
6287 makeinfo stop the build on cygwin (because they don't work).
6289 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
6291 * m4/m4private.h: ...is not a public header, so moved to src.

6335 From Akim Demaille <akim@epita.fr>
6337 2000-01-17 Gary V. Vaughan <gary@gnu.org>
6339 * src/ltdl.c: Use access() to abort doomed module load attempts
6340 if module file does not exist.
6342 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
6343 getopt1.o will already be used if appropriate, so I moved getopt.c
6344 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
6346 * modules/modpath1.test: Use correct filename in header line.
6347 * modules/modpath2.test: ditto.
6348 * modules/modpath3.test: ditto.
6349 * modules/modpath4.test: ditto.
6351 Without these changes lt_dlopen("test") attempts to

6353 generates a spurious error message which spoils most of the tests:
6354 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
6355 (TESTS): s/test.test /modtest.test /

6408 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
6411 2000-01-11 Gary V. Vaughan <gary@gnu.org>
6413 Merged the following changes from my tree:
6415 1999-06-15 Gary V. Vaughan <gary@gnu.org>
6417 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
6418 ported to compile shared libs.
6420 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
6421 use `__declspec(dllimport)' when linking libm4.la on win32.
6422 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
6424 * configure.in (M4OBJS): Discover whether we need the shipped
6425 implementation of getopt_long.
6426 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
6427 main binary here, as opposed to the module library in lib/libm4.la.
6429 1999-06-14 Gary V. Vaughan <gary@gnu.org>
6431 * modules/README: Updated to describe the improved libltdl based
6433 * README (cygwin): Added some compilation notes for building m4
6434 correctly under cygwin.
6435 * TODO: Cleaned out the entries for the module system since they
6436 are now implemented.
6438 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
6439 all instances of __P with M4_PARAMS.
6441 * lib/getdate.h: removed unreferenced file.
6443 * lib/m4private.h: New file to define the private interface to the
6444 token_data struct, which must be shared between m4module.c, and
6445 builtin.c but not exported to modules built from the installed
6446 m4module.h since it's size changes depending on compile time
6449 * src/m4.h: Lots of stuff moved to lib/m4module.h.
6451 * lib/m4module.h: New file to define the interface available when
6452 compiling m4 modules.
6453 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
6454 necessary for module compilation into this new file.
6456 * lib/Makefile.am (include_HEADERS): install headers (renamed to
6457 avoid nameclash with other system headers) necessary for compiling
6459 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
6460 so that modules can include the (renamed) installed headers and
6461 be guaranteed a matching implementation.

6463 * lib/m4obstack.h: renamed from obstack.h.
6464 * lib/m4regex.h: renamed from regex.h.
6465 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
6466 implementation, simply include the shipped version
6467 unconditionally, otherwise it is hard for a module to know
6468 whether the m4obstack.h header it is using matches the
6469 implementation it ends up linking against.
6470 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
6473 1999-05-18 Gary V. Vaughan <gary@gnu.org>
6475 * examples/misc.test: Don't run this test on machines which don't
6476 have a root user in /etc/passwd (e.g. cygwin).
6478 * tests/get-them (/^@example$/): Error messages might have a
6479 ``.exe'' suffix to the program name, or else use the libtool
6480 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
6481 of these cases are now catered for when comparing error messages
6483 * tests/other-tests/*.test: ditto.
6484 * examples/*.test: ditto.
6486 * tests/defs (M4): use libtool execute mode.
6487 * examples/defs (M4): ditto.
6489 * tests/get-them (END): explicitly close any open file.
6490 (printthem): In a regular expression, '{' is the start of a repeat
6491 count! Use `[{]' for a literal open brace.
6492 (/^@node /): Don't use substr on a string shorter than the trim
6495 1999-05-17 Gary V. Vaughan <gary@gnu.org>
6497 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
6499 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.

6513 2000-01-10 René Seindal <rene@seindal.dk>
6517 * TODO, NEWS: Cleaned up and updated.
6519 * src/m4.c (main): New variable exit_status for exit status in
6520 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
6521 file cannot be read instead of EXIT_SUCCESS.
6523 * src/builtin.c (m4_indir): Changed error message to help
6524 translators (from Akim Demaille <demaille@inf.enst.fr>).
6526 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
6529 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
6532 * src/input.c (match_input): Reordering of code, to avoid multiple
6533 calls to push_string_init() from obstack_grow(), which can happen
6534 with some compilers (found and fixed by James Bonfield
6535 <jkb@mrc-lmb.cam.ac.uk>).

6588 1999-11-09 Paul Eggert <eggert@twinsun.com>
6590 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
6591 and zero, as Solaris 7 cc does.
6592 (bcopy): Remove macro; no longer needed with new obstack.h.
6594 * src/output.c (freeze_diversions): Don't assume that a
6595 diversion size can fit in `int'. Check for diversion file
6596 size too large to be printed with `unsigned long'.
6598 * src/Makefile.am (CFLAGS): Omit -Wall.
6600 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.

6631 are modules, not linktime libraries.
6632 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
6633 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
6634 avoidance on exported symbols.

6642 into running executable before reading the source.
6643 (--module-directory): prepend a directory to the module search
6645 (module_init()): Do this the first time we load a module instead;
6646 if the module subsystem is broken normal m4 scripts can still run.
6647 * src/m4.h (install_builtin_table): is now exported.
6649 1999-03-26 Gary V. Vaughan <gary@gnu.org>
6651 * src/module.c: removed. No longer required.

6667 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
6668 * acm4/gettext.m4: removed. It causes a multiple definition vs.
6669 the installed gettext.m4 file when running aclocal.
6671 1999-03-25 Gary V. Vaughan <gary@gnu.org>
6673 * configure.in (AM_INIT_AUTOMAKE): bumped version number to

6683 (module_unload_all): use libltdl.
6684 * src/m4.c (module_init): initialise module loading on demand for
6685 better diagnostics, and so that m4 will still work even if
6686 the module code is broken.
6687 * src/m4.h (module_init): removed. No longer relevant.
6688 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on

6692 * modules/time.c (m4_macro_table): ditto.
6694 * bootstrap: New file. Runs all the autoutils in the right order
6695 after a fresh checkout, or a make maintainer-clean.

6714 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
6716 * src/module.c (module_try_load): Don't try to be clever and
6717 overwrite argument string. Instead allocate all constructed
6718 strings locally, since they can have arbitrary lengths. Make
6719 arguments pointers to const.
6720 (module_search): Simplify due to above change.
6722 1998-11-29 René Seindal <rene@seindal.dk>
6726 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): New tests.

6748 1998-11-28 René Seindal <rene@seindal.dk>
6750 * src/m4.c (main): New option --import-environment (no single
6753 * When configured with --with-gmp both the normal (fast) eval()
6754 and the gmp aware mpeval() are defined. To restore previous
6755 bahaviour use "define(`eval', defn(`mpeval'))".
6757 * tests/other-tests/gmp.m4: Changed to use mpeval().
6759 * src/evalmp.c: New file for compiling eval.c as gmp aware.
6760 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
6762 * src/eval.c: Now includes "numb.c" directly. Everything in this
6763 file must by static, except evaluate(), which is changed to
6764 mp_evaluate() if USE_GMP in force.
6766 * src/numb.c: Changed to be included by eval.c instead of being
6767 compiled separately. Everything is declared static.
6769 * src/numb.h: Removed declarations of functions, as numb.c is now
6772 * src/builtin.c: Declaration of m4_mpeval() added.
6773 Inserted `mpeval' in builtin table.

6782 * src/m4.c (main): m4 --version also shows which options were used
6783 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
6785 1998-11-27 René Seindal <rene@seindal.dk>
6787 * Error messages now always print program name before input file
6788 name as specified by GNU coding standards. Reported by Akim
6789 Demaille <demaille@inf.enst.fr>.
6791 * doc/m4.texinfo (Include): Change due to changed error message
6795 * tests/get-them: Minor change to sed script due to changed error
6798 * src/m4.c (print_program_name): New func used to print program
6799 name, input file and line number in error (). Used as an
6800 error_print_progname handler.
6801 (reference_error): Removed.
6802 (main): Assigns error_print_progname.
6804 * src/m4.h (M4ERROR): Removed reference_error ().

6811 warning of ambiguous 'else'.
6813 * src/module.c: Inserted search path code from path.c modified to
6815 (module_init): Configured default path used only if M4MODPATH is
6817 (module_try_load): Now reads libMODULE.la as generated by libtool
6818 for actual module name.
6819 (module_load): Gives better error messages on failure.
6821 * src/m4.h: Added declarations of structures and functions for
6822 generic search path handling.
6824 * src/path.c: Removed all module specific code and introduced new
6825 functions of more generic search path handling.
6827 1998-11-24 René Seindal <rene@seindal.dk>
6829 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
6830 included gettext, as <libintl.h> might not be found
6831 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
6833 1998-11-22 René Seindal <rene@seindal.dk>
6835 * src/output.c (insert_diversion): Fixed bug that might cause m4
6836 to read from standard output! Triggered by input
6837 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
6838 so now 'undivert(0)' does nothing.
6840 1998-11-18 René Seindal <rene@seindal.dk>
6844 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
6845 could be changed when compiling a illegal regexp, causing later
6846 use of the regexp to dump core.
6848 * src/module.c (module_load): Changed error message to conform to
6851 * src/m4.c (usage): Added message about reporting bugs.

6861 * acm4/modules.m4 (AM_WITH_MODULES): Redone completely to work
6864 * modules/Makefile.am: Changed completely to compile modules using
6865 libtool. The modules are compiled as shared libraries, and are
6866 renamed when installed.
6868 * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
6869 USE_SHL_LOAD to HAVE_SHL_LOAD
6871 * src/builtin.c (shipout_string): Now tests for a NULL string.

6897 * modules/Makefile.am: Now correctly compiles and installs
6898 modules in pkglibexecdir.

6901 These two are now initialised by autoconf macros.
6903 * src/path.c (module_env_init): MODULE_PATH is always on the
6906 * src/Makefile.am: Now generated pathconf.h which defined the
6907 default MODULE_PATH.
6909 * configure.in (pkglibexecdir): Added defintion of pkglibexecdir,
6910 where modules are installed.
6912 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
6913 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
6914 build and install automatically, and it is prepared for other
6915 interfacec than dlopen().
6917 * src/builtin.c (predefined_tab): Added __m4_version__ for the
6918 current version of GNU m4. It is a GNU extension.

7123 * configure.in (AC_OUTPUT): Removed checks/Makefile
7125 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
7126 the space when m4.texinfo is edited and whitespace.el is active.
7127 (Defn,example): idem.
7129 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
7131 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
7132 ../COPYING. ../Makefile is a file which is certainly present when
7133 test is executed in testSubDir. One can't be sure that the COPYING
7134 file is in .. or ../.. in all situations, the ../Makefile is
7137 * doc/m4.texinfo (Include): adjusted expected test output
7138 according to new tests, i.e. the input will always come from the
7139 file `in' created by the test.
7141 * tests/Makefile.am: Added three lines at the top to get
7142 esyscmd.1.test working.
7144 * tests/get-them: modified to generate clearer tests who will need
7145 less maintenance when new test examples are created in
7146 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
7147 need the generic file `defs') shell scripts creating `in', `ok',
7148 `out' and when apropriate `okerr' and `err' in the directory
7149 `testSubDir' when executed. The compare of `ok' and `out'
7150 (and of `okerr' and `err') will be the exit status of the test.
7151 `out' must match `ok' (and `okerr' must match `err') for the test
7154 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
7155 the tests generated by tests/get-them getting it input normally
7156 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
7157 (dot) before the numeric part) is reserved for all other (hand
7158 written) tests. The `+' means one or more times.
7160 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
7162 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to

7198 * src/numb.{c,h}: New files, implements multiple precision eval
7199 using GNU gmp. Originally submitted by John Gerard Makecki
7200 (johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.
7202 * doc/m4.texinfo (Eval): Added documentation for multiple
7203 precision arithmetic library support.
7205 * src/m4.{c,h}, src/eval.c, src/builtin.c, configure.in: Changes

7366 of $U, put underline in extensions rather than in basenames. Use
7367 implicit rules, now that regularity makes this possible.
7368 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
7369 of ansi2knr whenever it is needed.
7370 * configure.in: Adjusted for correct STACKOVF substitution.
7371 * src/debug.c (trace_format): When not __STDC__, use (...) as a

7661 * builtin.c (m4_undivert): Replace div by file, for avoiding the
7662 shadowing of this variable.
7663 * output.c (insert_diversion): Idem.
7665 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
7666 (input_init): Duplicate default quote and comment strings.
7667 (set_quotes): Free previous quote strings in all cases. Duplicate
7668 even default quote strings.
7669 (set_comment): Free previous comment strings in all cases.
7670 Duplicate even default comment strings.
7672 * configure.in: Updated for Autoconf 2.0.
7673 * Makefile.in (distclean-local): Also delete config.cache.
7675 * m4.c (usage): Reorganize the --help output by topic. Include a
7676 description for debugging flags.
7678 1994-07-29 François Pinard <pinard@iro.umontreal.ca>
7680 * configure.in: If sigaction is available and SA_ONSTACK defined,
7681 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
7682 defined, use sigvec. Else don't compile stackovf.c.
7683 * stackovf.c (setup_stackovf_trap): Idem.
7684 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
7687 1994-07-21 François Pinard <pinard@iro.umontreal.ca>
7689 * m4.c (usage): Replace printf par fputs.
7691 1994-07-18 François Pinard <pinard@iro.umontreal.ca>
7695 1994-07-17 François Pinard <pinard@iro.umontreal.ca>
7697 * configure.in: Check for sigaction and sigvec. Add a new delayed
7698 check for RLIMIT_STACK, combine in the checking for getrlimit.
7699 All those things are not universally available.
7700 * stackovf.c: Split setting up the trap handler and catching
7701 signals, for better taking care of various configure outcomes.
7702 * examples/stackovf.sh: Correct a typo.
7703 Reported by Eric Backus, Jim Avera and Jim Meyering.
7705 1994-07-16 François Pinard <pinard@iro.umontreal.ca>
7707 * ansi2knr.c: New version sent by its author, Peter Deutsch.
7709 1994-07-15 François Pinard <pinard@iro.umontreal.ca>
7711 * Makefile.in: Modify so parallel make will not try making
7712 lib/libm4.a twice simultaneously.
7713 Reported by Jim Meyering.
7715 1994-07-14 François Pinard <pinard@iro.umontreal.ca>
7717 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
7718 error message, for when no code possibility exists. Even if this
7719 line is completely #ifdef'ed out, it brings a syntax error.
7720 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
7722 * Makefile.in (install): Have install depend on all too, for lib
7723 to be remade as needed.
7725 * examples/stackovf.sh: Try ksh, bsh and bash for shells
7726 providing ulimit, instead of using only ksh.
7727 Reported by Jim Avera and Joseph E. Sacco.
7729 1994-07-12 François Pinard <pinard@iro.umontreal.ca>
7731 * Makefile.in (check): Have it depend on all instead of m4. In
7732 this way, a change in lib will be detected and processed.
7734 * builtin.c (numeric_arg): Use strtol and verify the conversion,
7735 instead of using sscanf which stops as soon as there is a
7736 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
7737 and divert(1xyzzy) were all accepted without any warning or error
7739 * m4.h: Declare strtol as long if not including stdlib.h.
7740 * configure.in: Check for limits.h, and replace strtol if missing.
7741 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
7742 * lib/strtol.c: New file, from elsewhere.
7743 Reported by Andreas Schwab.
7745 1994-07-07 François Pinard <pinard@iro.umontreal.ca>
7747 * macro.c (expand_macro): Cast value to (boolean) prior to
7748 assigning it to traced.
7749 Reported by Tom McConnell.
7751 * Makefile.in (m4): Always make all in lib first.
7752 Reported by Jim Meyering.
7754 1994-07-06 Jim Avera <jima@netcom.com>
7756 * stackovf.c: Isolated OS-dependent sections; Improved portability,
7757 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
7758 handlers), and a default error message if the fault address is not
7759 available (when neither siginfo.h nor BSD sigcontext are supported).
7760 * configure.in: Changes for stackovf.h: Check for sigcontext,
7761 sigaction, sigstack, and define rlim_t as int if necessary.
7762 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
7763 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
7764 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
7766 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
7768 * configure.in: Use AC_SET_MAKE.
7769 * Makefile.in: Use @SET_MAKE@.
7770 Reported by Jim Meyering.
7772 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
7773 Reported by Ian Taylor.
7775 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
7777 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
7778 because siginfo.h is unrelated to standard headers, and siginfo.h
7779 is already checked for.
7780 Reported by Joseph E. Sacco.
7782 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
7784 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
7787 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
7789 * builtin.c (substitute): Use \& to represent this part of the
7790 string which was matched by the whole regexp, instead of
7791 representing the whole string. Any usage of \0 issues a warning
7792 and acts like \&, it will disappear in some subsequent release.
7794 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
7796 * m4.c: Complete prototype for forwarded declaration of usage.
7798 * input.c (init_macro_token): Correct own reference in error
7799 message. Previous name get_macro_func was referred to instead.
7800 (next_char): Correct own reference in error message. Previous
7801 name advance_input was referred to instead.
7803 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
7804 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
7805 and_term, not_term, logical_not_term, cmp_term, shift_term,
7806 add_term, mult_term, exp_term, unary_term, simple_term): Add
7807 prototype to forwarded declarations. Declare parameter v1 as
7808 eval_t * instead of int *. Same for local variable v2 in dyadic
7809 functions. Same for result in exp_term.
7810 * builtin.c (m4_eval): Declare value as eval_t instead of int.
7811 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
7812 unsigned_eval_t instead of unsigned int. Change casts accordingly.
7813 (shipout_int): Cast first argument of ntoa to eval_t.
7814 Reported by Thorsten Ohl.
7816 * macro.c: Complete the prototypes of forwarded expand_macro and
7818 Reported by Thorsten Ohl.
7820 * m4.h: Define voidstar as void * or char * depending on __STDC__.
7821 The Ultrix 3.1 compiler cannot do much with void pointers.
7823 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
7824 * m4.c (xfree): Replace void * by voidstar.
7825 Reported by Tom McConnell.
7827 * ansi2knr.1: New, from elsewhere.
7828 * Makefile.in (DISTFILES): Distribute ansi2knr.1
7830 * Makefile.in (stamp-h.in): Avoid running ./config.status if
7831 stamp-h does not exist yet. This avoids running it a second time
7832 just after the initial ./configure.
7833 Reported by David MacKenzie and Tom McConnell.
7835 * m4.h: Replace the enum debug_info declaration with a series of
7836 #define's. The Ultrix 3.1 compiler would otherwise need casting
7837 (int) to most references, when used in expressions.
7838 Reported by Tom McConnell.
7840 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
7842 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
7843 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
7844 calls the compiler. Previously, FP_PROTOTYPES was only calling
7845 the preprocessor; by not being subject to CFLAGS, this was
7846 discouraging those flags asking for ANSI compilation.
7847 * acconfig.h: Document HAVE_PROTOTYPES.
7848 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
7849 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
7850 Reported by Eric Backus.
7852 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
7853 from the environment. Default CFLAGS to -g if not set.
7854 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
7855 * lib/Makefile.in: Have CFLAGS substituted from configure.
7856 Reported by Eric Backus and Tom McConnell.
7858 * configure.in: m4_undefine changeword before using AC_ENABLE.
7860 * m4.h: Declare prototypes for error (for ANSI compilers only),
7861 prefix_all_builtins and reference_error.
7862 Reported by Tom McConnell.
7864 * input.c (set_word_regexp): Do not try to initialize the array
7865 test from a string, this does not work with non-ANSI compilers.
7866 Reported by Eric Backus.
7868 * Makefile.in (dist): Clean examples/ before saving it.
7869 (distclean-local): Also remove stamp-h.
7870 Reported by Eric Backus.
7872 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
7874 Reported by Tom McConnell.
7876 * checks/Makefile.in (clean): Depends on mostlyclean.
7877 (mostlyclean): New goal.
7879 1994-06-24 François Pinard <pinard@iro.umontreal.ca>
7881 * Makefile.in (DISTFILES): Distribute install.sh.
7882 * install.sh: New file, copied from elsewhere.
7883 Reported by Assar Westerlund and Kaveh R. Ghazi.
7885 1994-06-23 François Pinard <pinard@iro.umontreal.ca>
7887 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
7888 * acconfig.h: Explain ENABLE_CHANGEWORD.
7890 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
7891 from code provided by Pete Chown]
7892 * m4.h: Add original_text field to u_t variant of union u.
7893 Declare TOKEN_DATA_FUNC macro.
7894 * builtin.c: Declare changeword.
7895 (m4_changeword): New function.
7896 * input.c: Include "regex.h", define variables with word regexps.
7897 (input_init): Initialize the word regexp.
7898 (set_word_regexp): New.
7899 (next_token): Declare local variables, use the previous code if
7900 default_word_regexp is true. Else, match using a new code. Save
7902 * macro.c (expand_token): Ship out original text if not a macro
7904 Reported by Krste Asanovic and Pete Chown.
7906 [These modifs all depend upon ENABLE_CHANGEWORD]
7907 * m4.h: Declare external user_word_regexp.
7908 * m4.c: Declare user_word_regexp, and initialize it from
7909 --word-regexp or -W, or NULL if not specified.
7910 * input.c: Use user_word_regexp if specified, instead of
7911 DEFAULT_WORD_REGEXP.
7913 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
7916 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
7917 * checks/Makefile.in: Empty the suffix list.
7918 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
7920 * m4.c: Declare nesting_limit and initialize it to 250.
7921 Implement -LNUMBER or --nesting-limit=NUMBER to change its
7923 * m4.h: Declare nesting_limit as external.
7924 * macro.c (expand_macro): Stop execution whenever nesting limit
7926 Reported by Bengt Mertensson.
7928 * eval.c (evaluate): Diagnose excess characters in eval input.
7929 Things like `eval(08)' used to return 0 with no diagnostic.
7931 * m4.h: Capitalize first letter of all macro arguments in
7934 * m4.c: Declare warning_status, initialize it to 0. Add new
7935 option -E, or --fatal-warnings, which sets warning_status to
7936 EXIT_FAILURE instead.
7937 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
7938 EXIT_FAILURE if not otherwise done by header files.
7939 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
7940 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
7941 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
7942 argument of all M4ERROR calls.
7943 Reported by Noah Friedman.
7945 * examples/incl-test.m4: Renamed from incl_test.m4.
7946 * examples/include.m4: Include incl-test.m4 instead of
7948 * examples/multiquotes.m4: Renamed from multi-quotes.m.
7950 1994-06-22 François Pinard <pinard@iro.umontreal.ca>
7952 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
7953 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
7954 also tested it on a Sun Sparc workstation running SunOS 4.x.
7956 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
7957 49.format check, abusing a `union values' argument with sprintf
7958 without selecting the proper field. Now, save the formatting type
7959 first, delaying the fetch of the corresponding argument.
7960 Reported by Joseph E. Sacco and Tom Quinn.
7962 * format.c (format): Remove const from char *fmt declaration when
7963 not HAVE_EFGCVT, because a NUL may be forced into it.
7965 * m4.h: Declare atof() when not STDC_HEADERS.
7966 Reported by Joseph E. Sacco.
7968 * Regenerate configure using Autoconf 1.11, this corrects a
7969 problem about an incorrect cpp seting on NeXT 3.1.
7970 Reported by Alexander Lehmann.
7972 1994-06-05 François Pinard <pinard@iro.umontreal.ca>
7974 * m4.h (_): Change argument from `x' to `Args'.
7976 1994-04-22 François Pinard <pinard@iro.umontreal.ca>
7978 * m4.h: Rename Args() to _().
7979 * m4.h: Remove extern specifier from all function declarations.
7981 1994-04-22 Jim Avera <jima@netcom.com>
7983 * stackovf.c: New file implementing stack-overflow detection.
7984 * configure.in: Check for getrlimit, sigaction. If all of
7985 standard headers, getrlimit and sigaction, define USE_STACKOVF and
7986 substitute ${U}stackovf.o for STACKOVF.
7987 * acconfig.h: Declare USE_STACKOVF.
7988 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
7989 * m4.h: Declare setup_stackovf_trap().
7990 * m4.c: Call setup_stackovf_trap().
7991 * tests/stackovf_test.sh: New file.
7993 1994-04-13 François Pinard <pinard@iro.umontreal.ca>
7995 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
7997 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
7999 1994-01-30 François Pinard <pinard@iro.umontreal.ca>
8001 * m4.h: Remove definition of volatile, not used anymore.
8002 Reported by Jim Meyering and Joseph E. Sacco.
8004 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
8005 of `if ... else /* nothing */' for if macros.
8006 Reported by Jim Meyering.
8008 * builtin.c (m4_regexp): Reorganize the code for avoiding a
8009 warning from gcc about `repl' possibly used before defined.
8010 Reported by Jim Meyering.
8012 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
8013 Reported by Jim Meyering.
8015 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
8017 * m4.h: Move the conditional definition of volatile after the
8018 inclusion of system files, because they may define it first.
8020 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
8022 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
8023 get around a problem with Alpha make seeing a syntax error, there.
8024 Reported by Vern Paxson.
8026 1994-01-03 François Pinard <pinard@iro.umontreal.ca>
8028 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
8029 Reported by Richard Stallman.
8031 1993-12-25 François Pinard <pinard@iro.umontreal.ca>
8033 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
8034 instead of AC_HAVE_FUNCS.
8035 Reported by Noah Friedman.
8037 1993-12-01 François Pinard <pinard@iro.umontreal.ca>
8039 * m4.c: Initialize show_help and show_version to zero.
8041 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
8042 Use them in exit() and usage() calls.
8044 1993-11-27 François Pinard <pinard@iro.umontreal.ca>
8046 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
8047 syserr() macro. Delete errref, add reference_error and M4ERROR.
8048 * m4.c: Replace errref, which was returning an input reference
8049 string, with reference_error, which prints it on standard error.
8050 * builtin.c, output.c: Use errno as second parameter to error,
8051 instead of using syserr() with %s.
8052 * *.c: Use M4ERROR instead of error: no more errref() with %s.
8053 Doing so, the program name appears after the input reference
8054 instead of before, which eases M-x next-error processing.
8056 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
8058 * checks/get-them: Escape braces with backslashes in patterns,
8059 because HPUX-9.01 awk needs this.
8060 Reported by Jim Meyering.
8062 1993-11-22 François Pinard <pinard@iro.umontreal.ca>
8064 * builtin.c: Declare "FILE *popen ();".

8067 macros, replace error_message_prefix() declaration by errref()'s.
8068 Declare xrealloc, for use in errref().
8069 * m4.c: Delete error_message_prefix() function, add errref().
8070 * *.c: Use error() systematically in place of all error macros,
8071 now that error() flushes stdout first. Make needed adjustments.
8073 * m4.h: Remove const in sys_errlist[] declaration, it creates
8074 conflicts on SGI and Alpha.
8075 Reported by Kaveh R. Ghazi.
8077 1993-11-20 François Pinard <pinard@iro.umontreal.ca>
8079 * m4.c: Include <getopt.h> instead of "getopt.h".
8081 * configure.in: Output to config.h. Use HAVE_FUNCS preferably.
8082 * acconfig.h: New, for documenting HAVE_EFGCVT.
8083 * Makefile.in: Distribute acconfig.h, .stamp-h.in and config.h.in,
8084 use them wherever appropriate. Also use -I. for compilations.
8085 * lib/Makefile.in: Use -I.. for compilations.
8086 * *.c: Include <config.h> or "config.h".
8088 * m4.h: Test for HAVE_MEMORY_H instead of NEED_MEMORY_H.
8089 * configure.in: Use AC_HAVE_HEADERS(memory.h), delete AC_MEMORY_H.
8091 1993-11-17 François Pinard <pinard@iro.umontreal.ca>
8093 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
8095 * input.c (input_init): Initialize quote and comment strings
8096 explicitely instead of calling set_quotes and set_comment: by
8097 doing so, we ensure we do not free uninitialized variables.
8099 * checks/check-them: Reverse arguments to both diff, so the
8100 expected is on the left and the obtained on the right.
8102 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
8103 macros. Delete declarations for m4error, warning, fatal and
8104 internal_error, add declaration for error_message_prefix.
8105 * m4.c: Delete m4error, warning, fatal and internal_error
8106 routines, add error_message_prefix routine.
8107 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
8108 warning with WARNING*, fatal with FATAL* and internal_error with
8110 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
8111 this is not needed anymore.
8113 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
8114 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
8115 and debug_message, add declaration for debug_message_prefix.
8116 * debug.c: Remove static specifier for FILE *debug declaration.
8117 Delete debug_print and debug_message routines, add
8118 debug_message_prefix routine.
8119 * builtin.c, debug.c: Replace debug_print routine calls with
8120 DEBUG_PRINT* macro calls.
8121 * input.c, path.c: Replace debug_message routine calls with
8122 DEBUG_MESSAGE* macro calls.
8124 * m4.h: Remove inclusion of <varargs.h>.
8125 * debug.c: Include <stdarg.h> or <varargs.h>.
8126 (trace_format): Use stdarg instead of varargs if __STDC__.
8128 * configure.in: Remove checks for vfprintf and _doprnt. These
8129 implementations use varargs tricks which are not portable enough.
8130 * lib/vfprintf.c: Deleted.
8131 * lib/_doprnt.c: Deleted.
8132 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.
8133 Reported by Joel Sherrill.
8135 * path.c (add_include_directory): Use xstrdup.
8137 * builtin.c (find_builtin_by_name): Declare static.
8139 * *.[ch]: Add const to a few "char *" declarations.
8141 * configure.in: Remove commented tests for fileno() and fstat().
8142 * debug.c: Remove comments about HAVE_FILENO and HAVE_FSTAT.
8144 * debug.c (debug_flush_files): New.
8145 * m4.h: Declares it.
8146 * builtin.c (m4_syscmd, m4_esyscmd): Use it.
8147 Reported by Nicolas Pioch.
8149 1993-11-12 François Pinard <pinard@iro.umontreal.ca>
8151 * Makefile.in (m4.dvi): Use m4.texinfo instead of m4.texi.
8152 Reported by Joel Sherrill.
8154 * builtin.c (prefix_all_builtins): Instead of the table size, use
8155 the null entry at end for stopping the loop. It was overwritten.
8156 Reported by Andreas Schwab and Jim Meyering.
8158 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
8159 Reported by Kaveh R. Ghazi.
8161 * macro.c (call_macro): Add * in (*SYMBOL_FUNC (sym)) (...).
8162 Reported by Karl Vogel.
8164 1993-11-09 François Pinard <pinard@iro.umontreal.ca>
8166 * m4.h: Do not define volatile if already defined.
8167 Reported by René Seindal.

8354 * Makefile.in, lib/Makefile.in: Put $(CFLAGS) after $(CPPFLAGS),
8355 so the installer can override automatically configured choices.
8356 Reported by Karl Berry.
8358 1993-01-15 François Pinard <pinard@iro.umontreal.ca>
8360 * lib/vfprintf.c: Stolen from Oleo distribution and adapted. The

8369 1993-01-01 François Pinard <pinard@iro.umontreal.ca>
8371 * Makefile.in, lib/Makefile.in: Reinstate $(CPPFLAGS), use it.
8372 Richard wants it there.
8374 1992-12-27 François Pinard <pinard@iro.umontreal.ca>
8376 * Makefile.in: Add DEFS to MDEFINES.
8377 * lib/Makefile.in (.c.o): Remove $(CPPFLAGS).

8386 macro.c, output.c, path.c, symtab.c: Change Copyright from
8387 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
8389 * examples/divert.m4: Deleted, this bug has been corrected.
8391 * Makefile.in (texclean, mostlyclean): New goals.
8393 * Makefile.in (clean): Remove clutter from ansi2knr.
8394 Reported by Pierre Gaumond.
8396 1992-12-20 François Pinard <pinard@iro.umontreal.ca>
8398 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user

8409 1992-12-19 François Pinard <pinard@iro.umontreal.ca>
8412 This is still a beta release for the future GNU m4 version 1.1.
8414 * lib/alloca.c: New, from elsewhere.
8415 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
8417 * m4.h: Do not define index/rindex if already defined. If
8418 FALSE/TRUE are already defined, do not redefine them, but merely
8419 define boolean typedef to int.
8421 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
8422 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
8423 because some C compilers do not like connectives with #ifdef.
8424 * m4.h: Define `volatile' only if __GNUC__, instead of once for
8425 __GNUC__ and once for __STDC__.
8426 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
8428 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
8429 Makefile dependencies. Without it, make keeps destroying and
8430 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
8432 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
8433 to diversion/DIVERSION, this was a spelling error.
8435 * m4.c: Declare version[], remove #include "version.h".
8436 * version.h: Deleted.
8437 * Makefile.in: Remove references to version.h.
8439 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
8440 production, by using a simpler and more robust algorithm. This
8441 solves the problem of synclines sometimes written in the middle of
8442 an output line. Delete sync_line() and output_lines variable.
8443 * m4.h: Remove sync_line prototype and output_lines declaration.
8444 * input.c (next_char), output.c (shipout_text): Remove references
8446 * input.c (push_file, pop_file): Merely put the value -1 in
8447 output_current_line instead of calling sync_line, for delaying a
8448 single `#line NUM FILE' before next output line. Do not test
8449 for sync_output, because this is unnecessary clutter.
8450 * output.c (make_divertion, insert_divertion): Idem.
8451 * input.c: Rename must_advance_line to start_of_input_line, for
8454 * debug.c (trace_header): Select a new debug line format, which
8455 better complies with GNU standards for formatting error messages.
8456 With option `-dfl', M-x next-error might be used on the output.
8457 * m4.c (vmesg): Adjust format of error output to GNU standards.
8458 * m4.texinfo: Adjust examples for `make check' to work.
8460 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
8461 case for enum debug_info constants, which were all lower case.
8463 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
8465 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
8466 collected patches. I tried a few times using newer regex.[ch], it
8467 mysteriously stopped aborting with this one. Insecure feeling...
8468 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
8470 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
8472 * m4.c: Change `--no-warnings' to `--silent'.
8473 Reported by David MacKenzie.
8475 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
8476 leave it off for now. See comment in m4.c for justification.
8477 Reported by David MacKenzie.
8479 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
8480 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
8482 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
8484 * Makefile.in: Ensure recursive cleaning is done before local
8485 cleaning for all clean goals.
8487 * builtin.c (ntoa): Ensure the value is always interpreted as a
8488 signed quantity, whatever the radix is.
8490 1992-11-18 Jim Meyering <meyering@idefix>
8492 * builtin.c, format.c, input.c: Split long lines.
8493 * m4.c: Use typedef macro_definition instead of struct
8495 * symtab.c: Use typedef symbol instead of struct symbol.
8497 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
8499 * *.[ch]: Remove all trailing whitespace, in code and comments.
8501 * configure.in: Find some awk.
8502 * Makefile.in: Add $(AWK) to MDEFINES.
8503 * checks/Makefile.in: Transmit $(AWK) to get_them.
8504 * checks/get_them: Use $AWK instead of gawk. Add a close in the
8505 awk script when switching files, because without this, mawk runs
8506 out of file descriptors.
8508 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
8510 * Makefile.in (realclean): Delete m4.info*.
8511 Reported by Jim Meyering.
8513 * Makefile.in: Adjust and link with checks/Makefile.
8514 * checks/Makefile.in: New.
8515 * configure.in: Output checks/Makefile.
8517 * checks/get_them: Have the dnl header of each test more
8518 recognizable by next-error, also use a better message.
8520 1992-11-16 Jim Meyering <meyering@idefix>
8522 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
8523 And use that only if __GNUC__ since we're using it's GCC-specific
8524 semantics that tell the compiler the associated function doesn't
8527 * builtin.c (substitute): Don't use character as an array index.
8528 (dumpdef_cmp): Make formal arguments `const void *' to avoid
8529 warnings with gcc -W -Wall on systems with qsort prototype.
8530 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
8533 * eval.c (most functions): Add parentheses to assignments used
8534 as truth values go avoid warnings from gcc -Wall.
8536 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
8537 any functions that don't need external scope.
8539 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
8540 (many functions and arrays): Declare `const'.
8542 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
8544 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
8545 removing the declaration from m4.h. Also rename false to FALSE
8548 * lib/Makefile.in (Makefile): New goal.
8550 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
8551 so heavily loaded. It gets more easily overridable, calling make.
8552 Reported by Jim Meyering.
8554 * Makefile.in (dist): Get .fname from the current directory name,
8555 instead of from version.h. I need updating many files manually,
8556 when the version changes, version.h is just one of them.
8558 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
8560 * m4.h: Remove the tag `boolean' on the enum introducing typedef
8561 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
8562 Reported by Tom McConnell.
8564 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
8566 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
8567 39.cleardiv, which were describing missing or spurious newlines.
8568 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
8569 do not depend on machine word size, `/bin/false' implementation,
8570 or `wc' output format. `make check' is more dependable, now.
8572 * checks/check_them: Summarize the failed tests by listing their
8573 name, at end. If none, issue `All checks successful'. Output
8574 `Checking' instead of `Input file:'.
8576 * checks/get_them, checks/check_them: Reindented.
8578 * Makefile.in (dist): chmod a+r before making the tar file.
8580 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
8582 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
8584 * input.c (next_token): Reinitialize token_buttom just after using
8585 it as a watermark with obstack_free. Or else, a future token, big
8586 enough for triggering reallocation of the obstack chunk, could
8587 void the initialized value of token_buttom, later causing panic in
8588 obstack_free. Rename token_buttom to token_bottom everywhere.
8590 * m4.h: Before declaring errno, first include <errno.h> and
8591 ensure that it does not define errno.
8592 Reported by Richard Stallman.
8594 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
8596 * builtin.c: Define and use DECLARE macro for builtins.
8598 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
8599 argument, this is a common idiom for introducing long comments.
8601 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
8602 arguments. The last argument was silently ignored.
8604 * m4.c (cmd_error): Add a missing semicolon before va_end().
8606 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
8608 * Makefile.in: Now handle protoized sources. Define and use U.
8609 Compile and use ansi2knr with old compilers. Update DISTFILES.
8610 Add `aclocal.m4' to `configure' dependencies.
8611 * ansi2knr.c: New, from Ghostscript distribution.
8612 * configure.in: Define U through FP_PROTOTYPES for old compilers.
8613 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
8614 * aclocal.m4: New, provide FP_PROTOTYPES.
8615 * m4.h: Conditionnaly protoized through Args, save for varags.
8616 * builtin.c: Protoized. Then:
8617 Include <sys/types.h> if size_t is not defined, before "regex.h".

8626 * m4.c: Protoized, save for varargs. Then:
8627 (xfree): Accept void * instead of char *.
8628 (xmalloc): Return void * instead of char *.
8629 (xrealloc): Accept and return void * instead of char *.
8630 * macro.c: Protoized.
8631 * output.c: Protoized.
8632 * path.c: Protoized. Then cast some (char *) over xmalloc's.
8633 * symtab.c: Protoized.
8635 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
8637 * m4.texinfo: Remove directory from diagnostics in 30.include,
8638 51.eval, 56.errprint and 57.m4exit tests.
8640 * m4.h: Remove declarations for int or void system functions, they
8641 cause more conflicting trouble than they make good.
8643 * configure.in: Avoid configuration header file. Add some tests.
8644 * m4.h: Remove #include "config.h".
8645 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
8646 Then, rewritten for better compliance with GNU standards.
8648 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
8650 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
8651 because of a misplaced #endif.

8654 according to GNU indent 1.6 advice.
8656 * configure.in: New, using Autoconf 1.2.
8657 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.

8682 * Makefile.in (check): Add m4 as dependency.
8684 * m4.c: Accept --no-warnings instead of --no_warnings, and
