3 Fix regression in argument collection, from 2008-01-21.
4 * m4/input.c (m4__next_token): When DEBUG_INPUT is defined,
5 undo argument collection optimisation for strings, so that
6 m4_print_token doesn't abort when it otherwise receives an
7 unprintable M4_SYMBOL_VOID type token.
9 2008-02-20 Eric Blake <ebb9@byu.net>
11 Stage 16: cache quotes and improve m4_arg_print.
12 Cache rather than always copying quotes when pushing $@ refs; in
13 particular, reconstruct single-byte quotes on the fly. Allow NUL
14 through m4wrap. Improve sharing of code that prints arguments.
15 Memory impact: slight improvement, due to cached quotes.
16 Speed impact: slight improvement, due to less copying.
17 * m4/m4module.h (m4_symbol_value_print, m4_symbol_print)
18 (m4_arg_print): Adjust prototypes.

27 (m4__quote_cache): New function.
28 (m4_set_syntax): Update caller.
29 * m4/symtab.c (m4_symbol_value_print): Add parameter.
30 (m4_symbol_print, dump_symbol_CB): Adjust all callers.
31 * m4/utility.c (m4_dump_args): Delete; callers should use
33 * m4/input.c (m4_push_wrapup_init, m4_push_wrapup_finish): Split
34 implementation, and allow embedded NUL.
35 (m4_print_token, pop_input, composite_print, composite_peek):
36 (composite_read, append_quote_token): Adjust all callers.
37 * m4/macro.c (trace_prepre, m4_arg_text, make_argv_ref):
39 (m4_arg_print): Add parameters.
40 (trace_pre): Rewrite in terms of m4_arg_print.
41 * modules/m4.c (errprint): Likewise.
42 (m4wrap): Rewrite to allow embedded NUL.

48 Fix out-of-bounds read for sanitized macro names, from 2008-02-06.
49 * m4/utility.c (m4_verror_at_line): Properly terminate the string.
50 Reported by Ralf Wildenhues.
52 * doc/m4.texinfo (Debuglen, Changesyntax): Fix typos.
54 2008-02-19 Eric Blake <ebb9@byu.net>
56 Clean up example on filtering defined symbols.

58 shortcoming in foreach.m4, and improve filter example by using
61 * src/main.c (usage): Fix typo.
63 2008-02-18 Eric Blake <ebb9@byu.net>
65 Avoid some magic numbers.
66 * m4/m4private.h (CHAR_EOF, CHAR_BUILTIN, CHAR_QUOTE, CHAR_ARGV)
67 (CHAR_RETRY): Define in terms of UCHAR_MAX.
68 * m4/syntax.c (m4_syntax_create, set_syntax_set)
69 (reset_syntax_set, check_is_single_quotes)
70 (check_is_single_comments, check_is_macro_escaped)
71 (m4_set_quotes, m4_set_comment): Likewise.

85 * doc/m4.texinfo (Improved forloop): Document advantage of $0.
86 (Improved foreach): Adjust dump from file.
88 Stage 15: return argv refs back to collect_arguments.
89 Collect an entire $@ reference at once rather than one argument at
90 a time, outside of quotes (but inside quotes, $@ is still
91 flattened for now). The skip_last field allows concatenation of
92 $@ with other text when collecting arguments.
93 Memory impact: noticeable improvement, due to better reuse of $@.
94 Speed impact: noticeable improvement, due to less parsing.
95 * m4/m4private.h (CHAR_ARGV): New input engine sentinel.
96 (enum m4__token_type): Add M4_TOKEN_ARGV.

142 * tests/modules.at (modules: text): New test.
144 Fix regression in command line -D option, from 2006-08-25.
145 * m4/m4private.h (m4_symbol_value_create): Delete fast accessor.
146 * m4/m4module.h: Fix typo.
147 * m4/symtab.c (m4_symbol_value_create): Prime the maximum number

168 2008-02-02 Eric Blake <ebb9@byu.net>
170 Consistently use size_t for number of arguments.

193 * modules/perl.c (perleval): Likewise.
195 Stage 14b: allow pushing argv references.
196 Push a $@ reference to the input engine in one go, rather than
197 pushing each element. For now, argument collection still gets one
198 argument of a $@ at a time; but the penalties of this patch make
199 it easier to manage $@ efficiently in future patches.
200 Memory impact: noticeable penalty, due to larger struct and O(n)
201 to O(n^2) on unboxed recursion.
202 Speed impact: noticeable penalty, due to more bookkeeping.

215 helper functions, to add parameters.
216 (m4_push_args): Adjust caller.
217 * m4/symtab.c (m4_symbol_value_print): Likewise.
219 Stage 14a: allow printing argv references.
220 Refactor symbol-value printing code for better sharing, and to
221 allow printing a contiguous text representation of a $@ ref.
224 * m4/m4module.h (m4_arg_print): New prototype.
225 (m4_symbol_value_print): Alter prototype.
226 * m4/input.c (struct input_funcs): Add parameter to peek_func.
227 (file_peek, builtin_peek, string_peek): Ignore new parameter.

230 to avoid infinite recursion in next patch.
231 * m4/macro.c (trace_prepre, trace_pre): Adjust callers.
232 (m4_arg_print): New function.
233 * m4/symtab.c (m4_symbol_value_print): Update signature.
234 (m4_symbol_print): Update caller.
235 * m4/output.c (m4_shipout_string_trunc): Update comments.
236 * m4/syntax.c (set_quote_age): Require comma as argument separator
237 when dealing with $@ as a unit.
238 * tests/builtins.at (ifelse): Augment test.
239 * doc/m4.texinfo (Changesyntax): Document changesyntax deficiency.
241 2008-01-31 Eric Blake <ebb9@byu.net>
243 Kill hack for M4 1.4.4.
244 * configure.ac (AM_GNU_GETTEXT_INTL_SUBDIR): Delete, now that
245 we require new enough autoconf which in turn requires M4 1.4.5.
247 2008-01-31 Gary V. Vaughan <gary@gnu.org>
248 and Eric Blake <ebb9@byu.net>
250 Depend on new libtool to use non-recursive build.

470 Stage 9: share rather than copy single-arg refs.
471 Use hooks of previous patch to create back-references to arguments
472 in the input engine, and inline short text rather than always
473 creating a FIFO link. Also start testing embedded NUL behavior.
474 Until the argument collection engine also shares references, the
475 memory usage increases.
476 Memory impact: noticeable penalty, due to longer life of argv
477 changing O(n) to O(n^2) on boxed recursion.
478 Speed impact: slight improvement, due less data copying.
479 * ltdl/m4/gnulib-cache.m4: Import memmem and quote modules.
480 * m4/m4module.h (m4_arg_scratch): New prototype.
481 * m4/m4private.h (m4__push_symbol): Add parameter.
482 (m4_arg_scratch): Add fast accessor.
483 (struct m4): Add expansion_level member, taken...
484 * m4/macro.c (expansion_level): ...from here. Adjust all users.
485 (expand_argument): Minor cleanup.
486 (expand_macro): Track scratch space per macro call.
487 (m4_arg_scratch): New function.
488 (m4_make_argv_ref): Call new function.
489 (m4_push_arg): Push reference to $0.
490 (m4_push_args): Rework separator usage, since separators will
492 (process_macro): Allow embedded NUL.
493 * m4/input.c (INPUT_INLINE_THRESHOLD): New define.
494 (m4__push_symbol): Add parameter. Inline short strings, and save
495 references through rescanning.
496 * m4/symtab.c (m4_set_symbol_value_text): Weaken assertion.
497 * modules/m4.c (errprint, index): Handle NUL transparently.
498 (dumpdef, translit): Use scratch space, rather than expansion
500 * modules/gnu.c (renamesyms, m4symbols): Likewise.
501 * tests/others.at (nul character): New test.
502 (iso8859): Quote absolute file name, remove XFAIL.
503 * tests/iso8859.m4: Avoid raw NUL in output.
504 * tests/null.m4: New file.
505 * tests/null.out: Likewise.
506 * tests/null.err: Likewise.
507 * Makefile.am (OTHER_FILES): Distribute new files.
508 * .gitattributes: Treat new files as text.
510 2007-12-17 Eric Blake <ebb9@byu.net>
512 Stage 8: extend life of references into argv.
513 Add hooks to lengthen the lifetime of arguments reused in a macro
514 expansion, rather than always discarding arguments at the end of
515 expand_macro. Rework the expand_macro obstacks to handle longer
516 lifetimes. For now, the hooks remain unused.
517 Memory impact: slight penalty, due to larger structs.
518 Speed impact: slight penalty, due to more bookkeeping.
519 * m4/system_.h (obstack_regrow): Delete.
520 * m4/m4private.h (struct m4_symbol_chain): Add level field.
521 (m4__push_symbol): Adjust prototype.
522 (m4__adjust_refcount): New prototype.
523 (DEBUG_MACRO) [DEBUG]: New debug control.
524 (struct m4__macro_arg_stacks): New structure.
525 (struct m4): Add arg_stacks, stacks_count fields.
526 * m4/m4module.h (m4_make_argv_ref): Add parameter.
527 * m4/macro.c (argc_stack, argv_stack): Delete, replaced by

546 (exp): Move and rename...
547 * tests/others.at (countdown): ...to this.
548 * doc/m4.texinfo (Improved foreach): Fix tracing usage in
551 2007-12-13 Eric Blake <ebb9@byu.net>
554 * doc/m4.texinfo (Inhibiting Invocation): Missed one instance in
559 2007-12-13 Paolo Bonzini <bonzini@gnu.org> (tiny change)
561 * doc/m4.texinfo (Inhibiting Invocation): Fix quoting of a quoting
563 Reported by Giovanni Toffetti.
565 2007-12-11 Eric Blake <ebb9@byu.net>
567 Stage 7: use chained input support in input parser.
568 Allow the LIFO input engine to rescan a macro expansion composed
569 of smaller chunks of FIFO data, rather than the old approach of a
570 monolithic string. For now, all chunks are still copied.
571 Memory impact: slight penalty, due to FIFO chain overhead.
572 Speed impact: slight penalty, due to extra bookkeeping.
573 * m4/m4private.h (m4__push_symbol): New prototype.
574 (struct m4_symbol_chain): Add const-safety.
575 * m4/symtab.c (m4_symbol_value_print): Simplify.
576 (dump_symbol_CB): Update caller.
577 * m4/input.c (struct m4_input_block): Alter u_c member, first
578 introduced 2006-10-25, but unused until now.
579 (composite_peek, composite_read, composite_unget)
580 (composite_print, init_builtin_token): Rewrite accordingly.
581 (m4_push_wrapup): No longer need trailing NUL.
582 (m4__push_symbol, make_text_link): New functions.
583 (m4_push_string_finish): Use them.
584 * m4/macro.c (m4_push_arg, m4_push_args): Likewise.
585 (expand_macro): Simplify logic of nesting_limit.
586 * src/main.c (main): Likewise.
587 * doc/m4.texinfo (Dumpdef): Augment test.
589 2007-12-08 Eric Blake <ebb9@byu.net>
591 Stage 6: convert builtins to push arg at a time.
592 Add new methods to factor all builtins whose expansion includes an
593 argument, making back-reference creation easier in future patches.
594 Factor out length-limited printing to obstacks, and use -1 rather
595 than 0 for unlimited length.
597 Speed impact: slight improvement, due to better code sharing.
598 * m4/m4module.h (m4_shipout_text): Rename...
599 (m4_divert_text): ...to this, to avoid confusion with m4_shipout_*
600 that does not worry about sync lines.
601 (m4_shipout_string_trunc): New prototype.
602 * m4/output.c (m4_shipout_text): Rename...
603 (m4_divert_text): ...to this.
604 (m4_shipout_string): Move guts...
605 (m4_shipout_string_trunc): ...to this new function.
606 * m4/macro.c (m4_push_arg, m4_push_args): New functions.
607 (expand_token, process_macro): Update callers.
608 * m4/input.c (string_print): Likewise.

612 (debuglen): Use SIZE_MAX for unlimited debug length.
613 * src/main.c (main): Likewise.
614 * m4/m4.c (m4_create): Default max_debug_length to SIZE_MAX, not
617 2007-12-07 Eric Blake <ebb9@byu.net>
619 Minor security fix: Quote output of mkstemp.
620 * modules/m4.c (m4_make_temp): Produce quoted output.
621 * doc/m4.texinfo (Mkstemp, Mkdtemp): Update the documentation and
624 Stage 5: add notion of quote age.
625 Cache the quoting rules that were in effect when a string was
626 parsed, to avoid reparsing that string if no changequote or other
627 quote age change took place in the meantime. A quote_age of 0 is
628 always safe, but does not benefit from caching.
629 Memory impact: slight improvement, due to smaller struct in input
631 Speed impact: slight penalty, due to more bookkeeping.
632 * m4/m4module.h (m4_get_symbol_value_quote_age): New prototype.
633 (m4_set_symbol_value_text): Adjust prototype.
634 (m4_has_syntax): Factor out the unsigned char cast.
635 * m4/m4private.h (struct m4_syntax_table): Add syntax_age and
637 (m4__quote_age, m4__safe_quotes): New accessor macros, no need for
638 functions at this point.

641 (m4_set_symbol_value_text): Adjust fast accessor.
642 (m4_get_symbol_value_quote_age): New fast accessor.

644 (m4_get_symbol_value_quote_age): New function.
645 (m4_symbol_value_copy): Adjust callers.
646 * m4/macro.c (expand_token): Add parameter, and track quote age.

663 * src/freeze.c (reload_frozen_state): Likewise.
664 * src/main.c (main): Likewise.
665 * modules/m4.c (define, pushdef): No need to set macro text.

668 * examples/wraplifo.m4: New file.
669 * Makefile.am (dist_pkgdata_DATA): Distribute new examples.
671 2007-12-04 Eric Blake <ebb9@byu.net>
673 Fix builds with OpenBSD make.
674 * Makefile.am (HELP2MAN): New macro.
675 (dist_man_MANS, doc/m4.1): Fix rules for building m4.1 into
677 * README: Update copyright.
678 * HACKING: Mention help2man and makeinfo dependencies.
680 2007-11-29 Eric Blake <ebb9@byu.net>
682 Stage 4: route indir, builtin through ref; make argv opaque.
683 Finish making struct opaque to all but the input engine, by
684 reworking obstack usage in expand_macro to better support creation
685 of a $@ reference. Canonicalize the empty argument, to allow
686 pointer comparison optimizations.
687 Memory impact: slight penalty, due to larger struct.
688 Speed impact: slight improvement, due to fewer function calls.
689 * m4/system_.h (obstack_regrow): Fix precedence.
690 * m4/m4module.h (m4_arg_equal, m4_arg_empty, m4_make_argv_ref):
692 (struct m4_macro_args): Move...
693 * m4/m4private.h (struct m4_macro_args): ...here, making it opaque
694 to modules. Add has_ref member.
695 (bool_bitfield): New helper typedef.
696 (struct m4_symbol_chain): Add flatten and len members.
697 * m4/macro.c (empty_symbol): New placeholder, for optimizing

705 (m4_arg_text, m4_arg_len, m4_arg_func): Use new methods.
706 * modules/m4.c (ifelse, syscmd): Likewise.

708 (undefine, popdef, m4_dump_symbols): Optimize.
709 * modules/gnu.c (builtin, indir, esyscmd, debugfile): Use new
711 (changesyntax, regexp): Optimize.
712 * m4/output.c (diversion_storage): Use typedef.
714 Stage 3b: cache length, rather than computing it, in modules.
715 Use cached token length in builtins and output engine.
717 Speed impact: noticeable improvement, due to fewer function calls.
718 * m4/hash.c (m4_hash_remove): Avoid double free on remove
720 * m4/output.c (m4_shipout_string): Change semantics of len param.
721 (m4_shipout_int): Use cached length.

729 * m4/symtab.c (m4_symbol_value_print): Likewise.
730 * modules/gnu.c (__file__, __program__, builtin, indir)
731 (m4symbols, mkdtemp, regexp_compile, regexp_substitute,
732 renamesyms, patsubst, regexp, regexp_compile): Likewise.
733 * modules/load.c (m4modules): Likewise.

742 * tests/builtins.at (mkstemp): Likewise.
743 * tests/others.at (iso8859): XFAIL this test, now that
744 length-based handling allows NUL through part but not all of M4.
746 2007-11-28 Eric Blake <ebb9@byu.net>
748 Stage 3a: cache length, rather than computing it, in libm4.
749 Cache the length of a token in the input engine and symbol table,
750 to avoid repeating lots of strlen calls. Additionally, by using
751 obstack length rather than strlen, the input engine can now
752 support embedded NUL.
753 Memory impact: slight penalty, due to larger struct.
754 Speed impact: slight improvement, due to fewer function calls.
755 * m4/m4module.h (struct m4_macro_args): Cache length.
756 (m4_get_symbol_len, m4_get_symbol_value_len): New accessors.
757 (m4_set_symbol_value_text): Change signature.

777 (m4_set_symbol_value_text, m4_set_symbol_value_placeholder):
778 Adjust implementation.
780 2007-11-27 Eric Blake <ebb9@byu.net>
782 Stage 2: use accessors, not direct reference, into argv.
783 Outside of macro.c, use accessor methods rather than direct access
784 into the argv struct.
786 Speed impact: slight penalty, due to increased function calls.
787 * m4/m4private.h (m4_arg_argc): New fast accessor.
788 * m4/m4module.h (m4_arg_argc, m4_arg_symbol, m4_is_arg_text)

791 (m4_builtin_func, M4BUILTIN, M4BUILTIN_HANDLER, m4_dump_args)
792 (m4_macro_call): Make argc unsigned.
793 (M4ARG): Use new accessors.

796 (traceon, traceoff): Make argc unsigned.
797 * modules/m4.h (m4_dump_symbols_func): Likewise.
798 * modules/evalparse.c (m4_evaluate): Likewise.
799 * modules/gnu.c (builtin, indir): Use new accessors.

806 (expand_macro, trace_pre, trace_post, m4_macro_call): Update argc
809 2007-11-24 Eric Blake <ebb9@byu.net>
811 Stage 1: convert m4_symbol_value** into new object.
812 Pass a variable-size wrapper structure instead of an array to
813 builtins, so that subsequent optimizations in the structure need
814 not impact every builtin client.
815 Memory impact: slight penalty, since struct is larger than array.
816 Speed impact: slight penalty, due to increased bookkeeping.
817 * ltdl/m4/gnulib-cache.m4: Import flexmember module.
818 * m4/m4module.h (m4_macro_args): New type, will be opaque to

883 2007-11-14 Eric Blake <ebb9@byu.net>
885 Handle some defn corner cases differently.
886 * doc/m4.texinfo (Defn): Update documentation; although this still
887 doesn't match the branch, since it may be changed before 2.0.
888 * m4/macro.c (expand_argument): Consistently ignore builtins in
889 concatenation contexts.
890 * m4/m4private.h (m4__symbol_type): Fix C89 compliance bug.
892 2007-11-13 Eric Blake <ebb9@byu.net>
894 Note: Patches titled Stage 0 through N form a series of patches
895 which decreases the algorithmic complexity of tail recursion in
896 macro expansions from O(n^2) to O(n) in both time and memory, then
897 performs cleanups, such as handling of embedded NUL, made easier
898 by the code refactoring.
900 Stage 0: Fix memory leak in tail recursion.
901 Free expansion text in the input engine as soon as it is parsed,
902 rather than when the recursive expansion completes.
903 Memory impact: noticeable improvement, due to reduction from
904 O(n^2) to O(n) on recursion.
905 Speed impact: minor improvement, due to better memory usage.
906 * m4/input.c (pop_input): Add flag parameter and return type.
907 (next_char): Adjust caller.
908 (m4_push_string_init): Let go of memory earlier.

3787 * Makefile.am (AM_CPPFLAGS): Add $(LTDLINCL), so the right
3790 * bootstrap: Do not run libtoolize manually, this is done
3791 correctly by autoreconf. Invoke autoreconf with --no-recursive
3792 to avoid unnecessary rerunning of autotools for libltdl.
3794 2006-06-13 Eric Blake <ebb9@byu.net>
3798 2006-06-12 Eric Blake <ebb9@byu.net>

3803 * m4/input.c (m4__next_token): Avoid bzero.
3804 * configure.ac (AC_CHECK_FUNCS): Remove obsolete checks.
3805 * Makefile.am (doc/m4.1): Depend on installed help2man, rather
3806 than distributing outdated helptoman.pl.
3807 * doc/helptoman.pl: Delete.
3809 2006-06-10 Eric Blake <ebb9@byu.net>
3811 * README (Patches): Document the current dependence on CVS

3833 about cygwin. Document bootstrapping dependency.
3834 * AUTHORS: Update from branch-1_4.
3835 * THANKS: Likewise. Change encoding to UTF-8.
3836 * BACKLOG: Delete. This file is too old and unmaintained to be
3838 * ChangeLog: Change encoding to UTF-8.
3840 Avoid compiler warnings.
3841 * m4/macro.c (trace_format): Don't mark this as a printf format,
3842 since we don't accept the same set of modifiers as printf. It
3843 would be nice if gcc let us specify a custom format archetype.
3844 * src/main.c (main): Cast away const.
3846 2006-06-10 Andreas Schwab <schwab@suse.de> (tiny change)

3866 * po/Makevars (MSGID_BUGS_ADDRESS): Add.
3867 * po/POTFILES.in (src/getopt.c, src/version-etc.c): These files live
3870 2006-05-06 Eric Blake <ebb9@byu.net>
3872 * configure.ac (LT_CONFIG_LTDL_DIR): Inform libtool which
3873 subdirectory to use.

3896 2005-12-05 Gary V. Vaughan <gary@gnu.org>
3898 * bootstrap (func_update_po): Synch with CVS GNU tar. wget 1.9.x
3899 and 1.10.x support --cache=off, so $WGETFLAGS are not necessary.
3900 Reported by Eric Blake <ebb9@byu.net>
3902 2005-12-04 Gary V. Vaughan <gary@gnu.org>
3904 * bootstrap (func_update_po): Test and set $WGETFLAGS to disable
3905 http caching as -C is no longer supported by wget 1.10.x.
3906 Reported by Eric Blake <ebb9@byu.net>
3908 2005-10-20 Gary V. Vaughan <gary@gnu.org>
3910 * m4/module.c (caller_id): To match libtool-2.0 interface, changed
3912 (iface_id): ...an lt_dlinterface_id type.
3913 (m4__module_find): New abstraction for lt_dlhandle_fetch. Use
3914 throughout, instead of calling obsolete lt_dlhandle_find directly.
3915 (m4__module_next): Use multiloader-safe lt_dlhandle_iterate. Use
3916 throughout, instead of calling obsolete lt_dlhandle_next.
3917 * m4/m4private.h (m4__module_find): Declare it.
3918 * m4/builtin.c (m4_builtin_find_by_name, m4_builtin_find_by_func):

3927 these files under source control anymore.
3928 Suggested by Eric Blake <ebb9@byu.net>
3930 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3932 * ltdl/m4/m4-gnulib.m4: Update FSF contact address. Somehow this
3933 file escaped the address updates on 2005-05-01.
3935 2005-07-07 Gary V. Vaughan <gary@gnu.org>
3937 * bootstrap: Allow user overriding of gnulib-tool location, and
3938 correctly determine module source directories whether gnulib-tool
3939 is given as a relative or absolute path, or is found by searching
3941 Reported by Eric Blake <ebb9@byu.net>
3943 2005-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3945 * ltdl/m4/debug.m4 (m4_CHECK_DEBUGGING): Make sure that both $rm
3946 and $RM are defined for various versions of
3947 AC_LIBTOOL_COMPILER_OPTION.
3949 * bootstrap (AUTORECONF): New variable to allow user overriding of

3955 GNU m4, and other historical interest.
3957 2005-05-08 Gary V. Vaughan <gary@gnu.org>
3959 * m4/symtab.c (m4_symbol_rename): New function that performs a low
3960 level symbol rename.
3961 * m4/m4module.h (m4_symbol_rename): Declare it as part of the API.
3962 * modules/gnu.c (regsub): Factored out of m4_epatsubst_do...
3963 (m4_patsubst_do, m4_renamesyms_do): ...wrappers that use
3965 (erenamesyms, renamesyms): ...builtins that use these to implement
3966 macro renaming by regular expression.
3967 * doc/m4.texinfo (Erenamesyms and Renamesyms): Document them.
3968 * tests/generate.awk: Allow some forbidden `m4_' prefixed symbols
3969 to stop the new generated tests from choking.
3971 2005-05-07 Gary V. Vaughan <gary@gnu.org>
3973 Since most of the build is handled from a single Makefile.am now,
3974 we can teach make about the dependencies between the m4 binary and
3975 the preopened modules it is built against:
3977 * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
3979 * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
3980 of the preopened modules have changed.
3982 2005-05-07 Gary V. Vaughan <gary@gnu.org>
3984 * configure.ac (gl_MODULES): Add mkstemp for machines that don't
3985 have a native implementation.
3987 2005-05-06 Gary V. Vaughan <gary@gnu.org>
3989 * src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are
3990 handled already by gnu/exit.h.
3992 * configure.ac (gl_MODULES): Add assert to support a
3993 --disable-assert configure time option for NDEBUG setting.
3995 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.
3996 * bootstrap (src_modules): Add version-etc-fsf.
3997 * src/main.c (version_etc_copyright): Removed.
3999 * ltdl/m4/m4-getopt.m4 (m4_GETOPT): Synch with gnulib/getopt.m4.
4001 2005-05-04 Gary V. Vaughan <gary@gnu.org>
4003 * src/m4.h (__CYGWIN__, WIN32): Canonicalise Windows and Cygwin
4005 * src/freeze.c (produce_frozen_state): Use \n line-endings even
4006 on Windows, so that the frozen file reader will work.
4007 Reported by Josef T. Burger <bolo@bolo.com>
4009 2005-05-04 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
4011 Forward port of a patch that allowed m4-1.4.2 to compile on
4014 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
4016 * src/m4.h: And include them as appropriate.
4017 * src/main.c, src/stackovf.h: Don't include signal.h literally;
4018 m4.h will include the correct file.
4020 2005-05-04 Gary V. Vaughan <gary@gnu.org>
4022 * m4/m4private.h: Make errno visible for the sources patched
4025 2005-05-04 Paul Eggert <eggert@twinsun.com>
4027 * src/main.c (print_program_name_CB): Preserve errno, since
4028 M4ERROR relies on this.
4029 * modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
4030 * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
4031 * m4/path.c (m4_path_search): Don't let "free" trash errno when
4034 * m4/output.c (m4_insert_file): Don't assume errno has a valid
4035 value simply because fread returns zero. This fixes a
4036 portability bug reported by Marion Hakanson in
4037 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
4039 2005-05-04 Santiago Vila <sanvila@debian.org>
4041 * tests/stackovf.test: Use tempfile if available.

4045 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=92629
4046 * m4/output.c (m4_insert_file): Do not mix buffered and
4047 unbuffered I/O, as this breaks on the Hurd.
4049 2005-05-04 Gary V. Vaughan <gary@gnu.org>
4051 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
4052 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
4053 and libtoolize does a better job of ltdl importing now too, so
4054 take advantage of that while updating the tree:
4056 * acm4, config: Moved from here...
4057 * ltdl/m4, ltdl/config: ...to here.
4058 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
4059 src/Makefile.am, tests/Makefile.am: Removed...
4060 * Makefile.am: ...and migrated to here, with adjustments to
4061 compensate for relative path differences.
4062 * commit: Adjust relative paths.
4063 * configure.ac: Adjust relative paths.
4064 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
4066 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
4067 the meanwhile, CVS HEAD libtool is needed.
4068 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
4069 stricly new enough, we also need a patch.
4070 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
4071 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
4072 (gl_MODULES): Don't list getopt and version-etc, as they don't
4074 * bootstrap: After running gnulib-tool to import the listed
4075 modules, fetch getopt and version-etc into src manually.
4076 (ltdldir): Change to ltdl.
4077 * src/main.c: Adjust for changes in version-etc API.
4078 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
4079 but works when the getopt module isn't to be included in the lib.
4080 * README: Add note about patching autoconf and automake to

4085 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=84416
4086 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
4087 empty file rather than to a nonexistent file. This closes a
4088 common security hole.
4089 * modules/m4.c (m4_maketemp): Implement the above, by using
4090 mkstemp rather than mktemp.
4092 2005-05-01 Gary V. Vaughan <gary@gnu.org>
4094 The FSF are moving offices today. Changed their contact address
4095 in all files from `59 Temple Place, Suite 330, MA 02111-1307' to

4122 2004-12-24 Eric Blake <ebb9@byu.net>
4124 * configure.ac (INCLUDE_STDBOOL_H): Account for gnulib's move
4125 to the gnu subdirectory.
4126 * acm4/m4-error.m4 (INCLUDE_ERROR_H): Likewise.
4127 * acm4/m4-obstack.m4 (INCLUDE_OBSTACK_H): Likewise.

4132 Gary V. Vaughan <gary@gnu.org>
4134 * m4/m4.c (m4_context_field_table, m4_context_opt_bit_table):
4135 Protect definitions from macro expansion under -DNDEBUG by
4136 parenthesising the expanded function names.
4137 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
4138 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
4139 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
4140 (m4_is_syntax_macro_escaped): Similarly protect function
4141 definitions from macro expansion under -DNDEBUG by #undefing the
4142 matching macro names before each definition. Also, move all the
4143 function definitions to the end of the file so that any
4144 invocations in the rest of the file pick up the fast macro
4146 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)
4147 (m4_set_debug_file, m4_set_trace_messages)
4148 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
4149 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
4150 (m4_set_max_debug_arg_length_opt): New fast macro versions of the
4151 option setter functions.

4158 2004-09-23 Gary V. Vaughan <gary@gnu.org>
4160 * src/main.c: Include gnulib files from the correct directory.
4162 * gnulib/*: Don't store any of the gnulib files in arch, as they
4163 generate spurious changes.
4164 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
4165 gnulib macros now share our macro directory.
4166 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
4167 * bootstrap: Call gnulib-tool to import from the gnulib tree.
4168 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
4169 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
4170 the gettext macros from autopoint that overwrite the gnulib-tool
4171 imported versions. Import sources and Makefile.am into the `gnu'
4172 directory. Changed all callers.
4173 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
4174 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
4175 for imported modules.
4176 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
4177 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
4178 hardcoding the gnulib macros they wrap.
4180 2004-07-15 Gary V. Vaughan <gary@gnu.org>
4182 Latest CVS libtool can preload modules in libraries, including
4183 its own module loaders! Tweak m4 so that it doesn't try to treat
4184 libltdl's module loaders as m4 modules when freezing and on exit:
4186 * gnulib/acm4/*.m4: Don't store these files in arch since they
4187 generate spurious changes.
4188 * bootstrap: Simplify initial libtoolize call, since CVS
4189 libtoolize is smarter these days.
4190 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
4192 * m4/module.h (m4__module_exit): Missing declaration.
4193 * m4/m4private.h (m4__module_next): New function declaration.
4194 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
4195 encapsulation. Changed all callers.
4196 (m4__module_interface): New function to verify m4 loadable module
4198 (m4__module_init): Register the interface validator.
4199 (m4__module_exit): Only close my own modules.

4203 * modules/modtest.c (export_test): Ditto.
4204 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
4205 * src/main.c (main): Bump copyright year.
4206 * tests/modules.at: Fix sed syntax error.
4209 2004-06-17 Gary V. Vaughan <gary@gnu.org>
4211 Tweaking to enable compilation with latest CVS libtool and
4212 libltdl. We can't just dump the library files directly into the
4213 m4 directory anymore now that libltdl is built from pieces itself:
4215 * bootstrap: Rewritten to use latest libtoolize sanely, and to
4216 set up libltdl subdirectory.
4217 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
4218 gnulib subdirectory's config.
4219 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
4220 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
4222 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
4223 configure.ac, so use AC_WITH_LTDL instead.
4224 * Makefile.am (SUBDIRS): Add libltdl.
4225 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
4227 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.

4234 2004-06-14 Gary V. Vaughan <gary@gnu.org>
4236 * gnulib/import: Now updates makefile fragments, and configure.ac.
4237 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
4238 * gnulib/m4/Makefile.am: include it.

4243 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
4244 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,

4261 2004-02-29 Gary V. Vaughan <gary@gnu.org>
4263 * config/mailnotify: New file for mailing commit notifications,
4264 imported from cvs-utils.
4265 * commit: Updated from cvs-utils and tweaked for m4.
4267 2003-12-01 Gary V. Vaughan <gary@gnu.org>
4269 * config/mkstamp: Updated from CVS libtool.
4270 * configure.ac: Generate a gnu coding standards compliant version
4271 number, and use it for the banner.
4272 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
4273 mhen the TIMESTAMP changes in ChangeLog, but the file modification
4274 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
4275 contain the previous version number.
4276 * src/main.c: Make --version output conform to the GNU standard.
4278 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
4279 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
4280 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
4281 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
4282 time_la_SOURCES): ...so that these are defaulted correctly, and
4283 can be removed from this file.
4284 (AM_LDFLAGS): Add -module...
4285 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
4286 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
4287 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
4288 the individual settings can be removed.
4289 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
4290 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
4291 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
4292 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
4293 time_la_LIBADD): ...so that these are picked up as a deplib of
4294 libm4 and don't need to be set explicitly.
4296 2003-11-18 Gary V. Vaughan <gary@gnu.org>
4298 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
4299 from the standard build. It is too fragile.
4301 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
4302 CVS libtool after merging m4 changes across to libtool.
4304 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
4305 * m4/path.c (search_path_add): Ditto.
4307 2003-11-13 Gary V. Vaughan <gary@gnu.org>
4309 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
4310 libtool tags we don't use in configure. This reduces the size
4311 of the script from over 1Mb to under 700Kb.
4313 2003-11-13 Gary V. Vaughan <gary@gnu.org>
4315 The import script was not written properly, and the last gnulib
4316 import was incomplete. Fixed that problem, and reimport our
4317 gnulib dependencies, which picks up the address calculation
4318 overflow checks described by Paul below. Also tweak the clients
4319 of the gnulib xalloc module not to use deprecated macros:
4321 * gnulib/import: Recurse through module dependencies rather than
4322 naively descending only one level.
4323 * configure.ac: Add calls to gnulib's strnlen and extension module
4325 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
4327 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
4328 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
4329 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
4330 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
4332 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
4333 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
4334 place of `xcalloc (1, S)'.
4335 * m4/m4.c (m4_create): Likewise.
4336 * m4/m4private.h (m4_symbol_value_create): Likewise.
4337 * m4/symtab.c (symtab_fetch): Likewise.
4338 * m4/syntax.c (m4_syntax_create): Likewise.
4339 * src/freeze.c (reload_frozen_state): Likewise.
4340 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
4342 * m4/symtab.c (m4_symtab_create): Likewise.
4344 2003-11-13 Gary V. Vaughan <gary@gnu.org>
4346 * tests/module.at: Comment typo.
4348 2003-10-10 Gary V. Vaughan <gary@gnu.org>
4350 * tests/modules.at (modules: importing): Apply some lateral
4351 thinking, and use AT_CHECK to compare the output of a sed pass
4352 over stderr against the canonical strerror string.
4354 * tests/modules.at (modules: importing): Edit the generated stderr
4355 output to canonicalize strerror output, before a comparison.
4357 2003-10-10 Gary V. Vaughan <gary@gnu.org>
4359 Tru64UNIX perl is sloppy with namespace pollution. This patch is
4360 careful not to trip over the mess:
4362 * modules/perl.c: Some builds of perl install headers that contain
4363 `#define try __builtin_try'. Be sure to undefine that macro
4364 before `m4/hash.h' gets included, which uses the `try' symbol.
4365 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
4366 `false' before including `stdbool.h'.
4367 (DELETE): This symbol is not in m4's namespace, and is in any
4368 case only used internally...
4369 * m4/m4private.h (DELETE): ...so move it to here.
4370 Reported by Martin MOKREJS <mmokrejs@natur.cuni.cz>
4372 2003-10-08 Paul Eggert <eggert@twinsun.com>
4374 Don't use XMALLOC and XCALLOC. Once we install the
4375 corresponding patch into gnulib, this will fix some
4376 address-calculation overflow bugs on hosts where calloc (A, B)
4377 returns garbage when A*B overflows.
4379 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
4380 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
4381 xmalloc, XCALLOC with xcalloc.
4382 * m4/m4.c (m4_create): Likewise.
4383 * m4/m4private.h (m4_symbol_value_create): Likewise.
4384 * m4/output.c (m4_output_init): Likewise.
4385 * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise.
4386 * m4/syntax.c (remove_syntax_attribute): Likewise.
4387 * src/freeze.c (reload_frozen_state): Likewise.
4388 * src/main.c (main): Likewise.
4390 2003-10-07 Gary V. Vaughan <gary@gnu.org>
4392 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
4393 gnulib/acm4 directories for aclocal m4 macros.
4394 * gnulib/Makefile.am (EXTRA_DIST): Removed.
4395 (MAINTAINERCLEANFILES): Add Makefile.in.
4396 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
4398 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
4399 * gnulib/import: New file. Temporary script for updating gnulib
4400 imported files, until gnulib-tool is working.
4401 * gnulib/config/codeset.m4, gnulib/config/error.m4,
4402 gnulib/config/exitfail.m4, gnulib/config/extensions.m4,

4438 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
4439 gnulib/acm4/xstrndup.m4: Reimported from CVS gnulib with
4440 gnulib/import script.
4441 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/error.c,
4442 gnulib/m4/error.h, gnulib/m4/exitfail.c, gnulib/m4/free.c,

4445 gnulib/m4/version-etc.c, gnulib/m4/version-etc.h,
4446 gnulib/m4/xalloc.h, gnulib/m4/xmalloc.c: Updated from CVS
4447 gnulib with gnulib/import script.
4448 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
4449 guards ready for gnulib-tool to autoupdate on import.
4450 * config/debug.m4, config/gmp.m4, config/m4-error.m4,
4451 config/m4-gettext.m4, config/m4-obstack.m4, config/m4-regex.m4,
4452 config/stackovf.m4: Moved from here...
4453 * acm4/debug.m4, acm4/gmp.m4, acm4/m4-error.m4,
4454 acm4/m4-gettext.m4, acm4/m4-obstack.m4, acm4/m4-regex.m4,
4455 acm4/stackovf.m4: ...to here, to separate aclocal macros from
4456 configure time helper scripts.
4457 * config/error.m4: Removed; superceded by gnulib/acm4/error.m4.
4458 * m4/hash.c, m4/m4.c, m4/macro.c, m4/module.c, m4/output.c,
4459 m4/path.c, m4/symtab.c, m4/syntax, m4/system_.h, modules/m4.c,
4460 src/main.c, src/stackovf.c: s/xfree/free/g to comply with new
4462 * src/main.c (version_etc_copyright): Only output the current
4464 (version_etc): Call with new variadic API.
4466 2003-09-16 Gary V. Vaughan <gary@gnu.org>
4468 * gnulib/m4/version-etc.c, gnulib/m4/version-etc.h: Import
4469 version-etc module from CVS gnulib.
4470 * po/POTFILES.in: Add gnulib/m4/version-etc.c.
4471 * src/Makefile.am: Build it.
4472 * src/main.c: Use it.
4474 * gnulib/m4/exit.h: Import exit module from CVS gnulib.
4475 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
4476 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
4479 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
4480 Gary V. Vaughan <gary@gnu.org>
4482 * bootstrap: Separate options.
4483 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
4484 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
4486 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
4487 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
4488 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
4489 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
4490 $(LTLIBINTL) for gettext support on cygwin.
4491 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
4492 have $(LTLIBINTL) from the preloaded module la files.
4493 * README: Remove the warning about using --disable-nls on Windows
4496 2003-09-15 Gary V. Vaughan <gary@gnu.org>
4498 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
4499 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
4502 2003-09-12 Gary V. Vaughan <gary@gnu.org>
4504 * doc/STYLE: Document the gnulib header naming conventions, and
4506 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
4507 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,
4508 gnulib/m4/gettext.h, gnulib/m4/obstack.h, gnulib/m4/regex.h
4510 * gnulib/m4/Makefile.am: Remove the rules to build these headers.
4512 * gnulib/m4/strtol.c, gnulib/config/strtol.m4: Import strtol
4513 module from CVS gnulib.
4514 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
4515 (gl_FUNC_STRTOL): In favour of the module macro.
4517 2003-09-12 Gary V. Vaughan <gary@gnu.org>
4519 Replace the getopt code with CVS gnulib getopt. The source files
4520 detect whether they are in a glibc environment and preprocess away
4521 all of the code if there is a system getopt, so we can compile
4522 them into the m4 executable unconditionally:
4524 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
4525 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
4526 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
4528 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
4530 * src/Makefile.am: Adjust.
4531 * src/main.c: Always include our shipped getopt.h.
4532 * po/POTFILES.in: Use new location of getopt.c.
4534 2003-09-12 Gary V. Vaughan <gary@gnu.org>
4536 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
4537 * config/Makefile.am: Removed. Automake 1.8 distributes the files
4538 in this directory automatically.
4539 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
4541 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
4543 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
4545 * modules/Makefile.am (pkglibexecdir): Set it here.
4546 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
4548 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
4549 Import regex module from CVS gnulib.
4550 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
4551 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
4552 do extra substitutions for Makefile.
4553 * configure.ac: Use it.
4554 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
4555 from regex_.h if necessary.
4556 * m4/system_.h: Include the correct version of regex.h.
4557 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
4559 * po/POTFILES.in: Use new location of regex.c.
4561 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
4562 realloc.c: automake distributes these files already.
4564 2003-09-12 Gary V. Vaughan <gary@gnu.org>
4566 Replace the xstrzdup code by importing the xstrndup module from
4567 CVS gnulib, along with its dependencies: strndup and strnlen:
4569 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
4570 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
4572 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
4573 gnulib/config/strndup.m4: Ditto wrt strndup.
4574 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
4576 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
4577 However, contrary to gnulib, we install xstrndup.h.
4578 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
4579 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
4580 is an artifact of the old m4 portability layer.
4581 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
4582 * m4/system_.h: Include xstrndup.h.
4583 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
4585 2003-09-11 Gary V. Vaughan <gary@gnu.org>
4587 Reimport the latest xalloc module from CVS gnulib, and adjust the
4588 m4 sources to take advantage of xalloc xfree. Also create a new
4589 macro DELETE with the same semantics as the old m4 XFREE macro,
4590 and carefully tweak callers:
4592 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
4594 * m4/utility.c (xfree): Removed. This function is now supplied by
4596 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
4597 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
4598 * m4/symtab.c (m4_symtab_create): Ditto.
4599 * m4/system_.h: Removed XFREE redefine.
4600 (DELETE): New macro with same functionality as the original m4
4601 XFREE macro, but based on xalloc.h now. Changed all callers.
4602 * src/main.c (main): Use XMALLOC macro.
4603 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
4605 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
4607 2003-09-10 Gary V. Vaughan <gary@gnu.org>
4609 Import the xalloc module from CVS gnulib, along with its
4610 dependencies: exitfail, malloc and realloc. We had different
4611 semantics for our XFREE and a function xfree() not supplied by
4612 gnulib, so also a bit of work to keep everything running
4615 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
4616 (gl_XALLOC): Use gnulib equivalents.
4617 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
4618 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
4619 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
4620 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
4622 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
4623 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
4624 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
4626 (pkgincdir): Removed. Use pkgincludedir instead.
4627 * m4/m4private.h (XFREE): xfree already checks for NULL.
4628 * m4/system_.h: Use xalloc module, and remove macros already
4629 supplied by xalloc.h.
4630 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
4631 moved the old definition from m4/xmalloc.c to here for now.
4633 2003-09-09 Gary V. Vaughan <gary@gnu.org>
4635 Import the error and progname modules from CVS gnulib. Our old
4636 error.c subsumed the functionality of both, so a little adjustment
4637 was required to accomodate the split in sources. Also added more
4638 wrapper macros to choose between a system installed error.h or our
4639 shipped gnulib error module:
4641 * m4/error.c, m4/error.h: Removed.
4642 * m4/Makefile.am: Adjust.
4643 (pkgincdir): Removed. Use pkgincludedir instead.
4644 * m4/module.h, src/main.c: Don't include `m4/error.h'.
4645 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
4647 * gnulib/m4/progname.c: Imported from CVS gnulib.
4648 * gnulib/m4/progname.h: Ditto.
4649 * src/main.c: Adjust to use progname module.
4650 * gnulib/m4/error.c: Imported from CVS gnulib.
4651 * gnulib/m4/error_.h: Ditto.
4652 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
4653 if appropriate, and link a local error.h if the system version is
4655 (libgnu_la_SOURCES) Add progname module sources.
4656 * gnulib/config/error.m4: Imported from CVS gnulib.
4657 * gnulib/config/strerror_r.m4: Ditto.
4658 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
4659 to have ERROR_H for Makefile substitutions and tell system.h
4660 whether the system error.h should be used, or a locally installed
4662 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
4664 2003-09-09 Gary V. Vaughan <gary@gnu.org>
4666 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
4667 s/gettext_.h/gettext.h/.
4669 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
4670 automake have been fixed.
4672 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
4673 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
4674 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
4675 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
4677 2003-09-09 Gary V. Vaughan <gary@gnu.org>
4679 The gnulib obstack module requires the gnulib gettext module for
4680 systems that do not have GNU gettext installed. Because we use
4681 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
4682 that directory incase it clashes with the system gettext.h. This
4683 delta uses gettext_.h and extra rules in the Makefile to make a
4684 link to gettext.h when needed:
4686 * Makefile.am (auxdir): Removed. No longer used.
4687 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
4688 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
4690 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
4691 Makefile based build.
4692 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
4693 of the macros are kept.
4694 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
4695 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
4696 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
4697 distributes these automatically.
4698 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
4699 warning from automake-1.7a.
4700 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
4701 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
4703 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
4704 wrt. m4_FUNC_OBSTACK.
4705 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
4706 wrt. m4_sys_STACKOVF.
4707 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
4708 wrt. _m4_LIB_GMP, m4_LIB_GMP.
4709 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
4710 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
4712 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
4713 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
4714 gettext.h link on deficient systems.
4715 (pkginc_HEADERS): Mention $(GETTEXT_H).
4716 (EXTRA_HEADERS): Mention gettext.h.
4717 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
4718 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
4719 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
4720 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
4721 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
4722 gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
4723 gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
4724 gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
4725 gnulib/config/po.m4, gnulib/config/progtest.m4,
4726 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
4727 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
4729 2003-09-05 Gary V. Vaughan <gary@gnu.org>
4731 We can't mirror the gnulib directory structure here, since we need
4732 to be able to eg. `#include <m4/obstack.h>' from our source files,
4733 which is much easier if the local obstack.h is created in a
4734 directory named m4. Rather than trying to symlink everything into
4735 the m4 directory, now we build a libtool convenience library from
4736 the sources we get from gnulib and link that with libm4.la:
4738 * gnulib/config/extensions.m4: Imported from CVS gnulib.
4739 * gnulib/config/unlocked-io.m4: Ditto.
4740 * gnulib/m4/unlocked-io.h: Ditto.
4741 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
4742 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
4743 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
4744 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
4745 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
4746 * m4/Makefile.am: Adjust.
4747 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
4748 macros we redistribute.
4749 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
4750 library among others.
4751 (GNULIB_SRCS, GNULIB_MACROS): Removed.
4752 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
4753 * config/m4-obstack.m4: Adjust.
4754 * po/POTFILES.in: Adjust.
4755 * configure.ac: Reformatting. Call newly imported gnulib macros.
4756 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
4757 bogus calls of `#include "m4.h"'.
4758 * Makefile.am: INCLUDES has been deprecated in favour of
4760 * m4/Makefile.am: Ditto.
4761 * modules/Makefile.am: Ditto.
4762 * src/Makefile.am: Ditto.
4764 2003-09-05 Gary V. Vaughan <gary@gnu.org>
4766 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
4768 2003-09-04 Gary V. Vaughan <gary@gnu.org>
4770 Migrate the obstack support into the gnulib directories for easy
4771 synchronisation with upstream files in gnulib:
4773 * config/gnu-obstack.m4: Moved from here...
4774 * config/m4-obstack.m4: ...to here.
4775 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
4776 * m4/obstack.c, m4/obstack_.h: Moved from here...
4777 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
4778 * po/POTFILES.in: Adjust.
4779 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
4780 * m4/Makefile.am: Add a whole new section to link the obstack
4781 sources from the gnulib tree if necessary.
4782 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
4784 * config/m4-obstack.m4: Rewrite as a wrapper for
4785 gnulib/m4/obstack.m4.
4787 2003-09-04 Gary V. Vaughan <gary@gnu.org>
4789 GNU M4 currently builds with a number of files adapted from
4790 upstream sources. Recently the gnulib project on savannah.gnu.org
4791 has pulled together a great many of these externally maintained
4792 files. This delta is the beginnings of isolating those files
4793 maintained in gnulib to make it easy to synchronise M4 with the
4794 upstream files prior to releases.
4796 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
4798 (SUBDIRS): Added new gnulib subdirectory.
4799 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
4800 * config/stdbool.m4: Moved from here...
4801 * gnulib/m4/stdbool.m4: ...to here.
4802 * m4/stdbool_.h: Moved from here...
4803 * gnulib/lib/stdbool_.h: ...to here.
4804 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
4806 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
4807 code to work with new stdbool_.h location.
4808 (gnulib_srcdir): New.
4810 2003-09-04 Gary V. Vaughan <gary@gnu.org>
4812 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
4813 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
4815 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
4816 (EXTRA_DIST): Use it.
4818 * bootstrap: CVS autoreconf leaves file droppings. Remove
4819 aclocal.m4t incase autoreconf doesn't.
4821 2003-08-29 Gary V. Vaughan <gary@gnu.org>
4823 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
4824 the other gnulib imports, renamed to m4/obstack_.h.
4825 * m4/obstack.c: Updated from CVS gnulib.
4826 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
4827 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
4828 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
4829 about vpath already, and $top_srcdir upsets CVS Automake, so the
4830 $top_srcdir reference was removed.
4832 * m4/system-h.in: For consistency with the gnulib imports, renamed
4834 * m4/Makefile (EXTRA_HEADERS): Adjust.
4835 * configure.ac (AC_CONFIG_FILES): Adjust.
4837 * m4/stdbool_.h: New file from gnulib for systems without their
4839 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
4840 * config/stdbool.m4: New file. Macros from gnulib for same.
4841 * configure.ac: Use it.
4843 2003-08-27 Gary V. Vaughan <gary@gnu.org>
4845 * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'`

4892 * src/main.c: Ditto.
4893 * src/stackovf.c: Ditto.
4895 * config/gmp.m4 (M4_AC_LIB_GMP): Use AC_INCLUDES_DEFAULT:
4896 ac_default_headers is an autoconf internal variable.
4897 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
4898 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
4900 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
4901 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
4904 2003-08-15 Gary V. Vaughan <gary@gnu.org>
4906 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
4908 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
4909 possible or faking one with a typedef. Changed all callers.
4911 2003-08-15 Gary V. Vaughan <gary@gnu.org>
4913 Still cleaning up the users' module API, by taking out the stuff
4914 that isn't used by any existing modules, and moving specialised
4915 functions out of libm4 and into the module they are used by.
4917 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
4918 * m4/utility.c (m4_skip_space): ...to here the home of its only
4919 use, made static and renamed to `skip_space'. Changed all
4921 * m4/m4module.h (m4_expand_ranges): Removed prototype.
4922 * m4/utility.c (m4_expand_ranges): Moved definition from here...
4923 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
4925 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
4927 * modules/gnu.c (builtin_syntax): Import and use in this
4928 builtin implementation.
4929 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
4931 * m4/macro.c (trace_flush): Except here where the macro is now
4933 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
4934 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
4936 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
4937 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
4939 2003-08-14 Gary V. Vaughan <gary@gnu.org>
4941 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
4942 compiler based AC_CHECK_HEADER that was introduced in
4944 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
4945 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
4946 * configure.ac: Use renamed M4_AC_LIB_GMP.
4948 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
4949 macro that requires arguments! This stops the shell's bad
4950 substitution error at configure time.
4952 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
4953 variables to the testsuite shell. Set the value of USE_GMP so
4954 that the gmp test will run!
4955 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
4957 2003-08-11 Gary V. Vaughan <gary@gnu.org>
4959 Libltdl already has an excellent mechanism for accessing C symbols
4960 in modules. Lets use that! Remove all the exporting cruft and
4961 just use lt_dlsym in conjunction with a few conventions to
4962 simplify module writers' jobs. Also removed the table address
4963 caching code and otherwise simplified the module loader quite a
4964 bit. To access exported symbols in other modules, first the
4965 exporting module must name the symbols <modname>_LTX_<symname>,
4966 and the importing module must define a function type called
4967 <symname>_func. The importer then adds
4968 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
4969 that wishes to call out to the exported functions. Care must be
4970 taken that <symname> is non-NULL in the importing module incase
4971 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
4972 definition was in the importers source. Study
4973 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
4974 m4_module_import will attempt to automatically load a module
4975 required for symbol access if it is not loaded already.
4977 * TODO: Removed the items fixed in this delta.
4978 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
4980 * m4/ltdl.h (lt_dlhandle_find): Declare it.
4981 * m4/module.c (m4_module_unload): Use it.
4982 * src/freeze.c (reload_frozen_state): Ditto.
4983 * m4/m4module.h (m4_export): Deleted. Removed all references.
4984 (M4_MODULE_IMPORT): New user convenience macro for importing
4985 arbitrary symbols from other modules.
4986 * m4/module.c (m4_module_import): New function to service
4987 M4_MODULE_IMPORT macro.
4988 (module_data): Removed. Looking up the tables on demand with
4989 lt_dlsym, rather than caching their addresses here simplifies the
4991 (m4_get_module_builtin_table, m4_get_module_macro_table):
4992 Removed. Changed all callers.
4993 (set_module_macro_table, set_module_builtin_table): Renamed to
4994 install_macro_table and install_builtin_table respectively, and
4995 simplified now that the cache is no more.
4996 * modules/gnu.c (builtin_symbols): Use this new mechanism to
4997 import m4_dump_symbols from the m4 module.
4998 (builtin_esyscmd): Likewise for m4_set_sysval and
5000 * modules/m4.c (m4_export_table): Removed. Functions are
5001 addressed with the new mechanism which doesn't need this.
5002 (m4_set_sysval): New exported accessor function to prevent
5003 problems with variable access on inferior architectures.
5004 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
5005 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
5006 that we can have some type safety.
5007 * modules/modtest.c (export_test): C level exported function for
5008 testing the new import mechanism.
5009 * modules/import.c: New file for the import end of the test.
5010 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
5011 * tests/modules.at: New test cases for intermodule symbol
5014 2003-08-07 Gary V. Vaughan <gary@gnu.org>
5016 * m4/m4module.c (m4_string): Moved from here...
5017 * m4/m4private.c (m4_string): ...to here.
5019 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
5021 2003-07-29 Gary V. Vaughan <gary@gnu.org>
5023 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
5024 already available to module writers through
5025 m4_{get,set}_nesting_limit_opt(), so moved from here...
5026 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
5027 (m4_create): Use it.
5029 2003-07-28 Gary V. Vaughan <gary@gnu.org>
5031 Aside from auditing path.c for m4module.h api obfuscation, this
5032 delta introduces the concept of private struct members in opaque
5033 data types to GNU m4: See the STYLE file for details.
5035 * TODO: Remind ourselves that a rewrite of path.c is needed.
5036 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
5038 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
5039 here and renamed. These type definitions are for internal api use
5040 only. Changed all callers.
5041 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
5043 * m4/path.c (search_path_env_init, search_path_add): ...to here
5044 and renamed. These calls were never used outside this file.
5045 Changed all callers.
5046 (dirpath): Moved functionality of this static declaration...
5047 * m4/m4private.h (struct m4): ...to this new internal only
5048 search_path field. Changed all callers.
5049 (m4__get_search_path): Added new internal api accessor.
5050 * m4/path.c (m4_search_path_info_new): Removed. Not used.
5051 (m4_include_init): Removed...
5052 * m4/m4.c (m4_create): ...because the new m4 field is now
5054 (m4_delete): Recycle search_path memory.
5055 * src/main.c (main): Don't call m4_include_init now that it's
5057 * doc/STYLE: Document convention for private fields in opaque
5060 2003-07-24 Gary V. Vaughan <gary@gnu.org>
5062 Sometimes exporting the address of a symbol from a module isn't
5063 enough for other modules to call that symbol correctly. If
5064 custom data types are used for function parameters, they need to
5065 be known to the caller. This change introduces the concept of
5066 $(prefix)/include/modules/$(modulename).h to declare those
5067 structures. Also we move m4_dump_symbols from libm4 to the m4
5068 module to show this concept in action.
5070 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
5071 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
5072 exporting data structures from modules/m4.c.
5073 * modules/m4.c, modules/gnu.c: Include it.
5074 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
5075 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
5077 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
5079 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
5080 ...to here, with slight renaming.
5081 (m4_export_table): Prototype and add m4_dump_symbols.
5082 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
5083 definition of m4_dump_symbols.
5084 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
5085 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
5087 2003-07-24 Gary V. Vaughan <gary@gnu.org>
5089 Create an export table in modules/m4.c in readiness for beefing up
5090 the module loader to track module exports and imports.
5092 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
5093 * m4/debug.c (m4_debug_flush_files): Moved...
5094 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
5095 * modules/gnu.c (builtin_esysval): Use it.
5096 * m4/m4module.h (m4_export): New type for declaring module symbols
5098 * modules/m4.c (m4_export_table): List symbols exported from this
5099 module for use by other modules.
5101 2003-07-24 Gary V. Vaughan <gary@gnu.org>
5103 An experiment: There is loads of code in libm4 which should be in
5104 the m4 module, but is also used by another module. Just because
5105 some linkers won't cope with calls across dynamic runtime loaded
5106 objects I initially left the code in libm4. It will tidy the
5107 module api immensely if this code moves to the right place, I just
5108 need to remember to invent a suitable calling mechanism at some
5109 point. For now, only modules that are statically linked and
5110 preloaded will get this treatment, so the only platforms that will
5111 break are those that require all symbols to be resolved at link
5114 * TODO: Reminder that what I am doing could reduce portability
5115 unless I do something more robust later.
5116 * m4/m4module.h (m4_sysval): No longer exported from libm4.
5117 * m4/utility.c (m4_sysval): No longer declared in libm4.
5118 * modules/Makefile.am: Reformatting.
5119 * modules/m4.c (m4_sysval): Declare it at place of use.
5120 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
5122 2003-07-23 Gary V. Vaughan <gary@gnu.org>
5124 * m4/m4module.h: Reformatting and rearranging lines a bit.
5125 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
5127 (m4_call_macro, m4_expand_input): Renamed...
5128 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
5130 (m4_expansion_level, m4_process_macro): Moved...
5131 * m4/macro.c (expansion_level, process_macro): ...to here, and
5134 * m4/m4module.h (program_name): Not used by modules at all, so
5136 * src/main.c (program_name): ...to here.
5137 (print_program_name): Renamed...
5138 (print_program_name_CB): ...to conform to the STYLE guide.
5140 2003-07-23 Gary V. Vaughan <gary@gnu.org>
5142 More refactoring of the m4module.h API. Replace #defines with an
5143 enum, and move non-public functions out of the public API.
5145 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
5147 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
5148 * m4/debug.c (m4_debug, trace): Moved...
5149 * m4/m4private.h (struct m4): ...to fields of this struct.
5150 (m4_get_debug_file, m4_get_trace_messages): New fast access macros

5153 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
5154 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
5155 * m4/m4module.h (m4_context_field_table): Add entries for new
5156 debug_file and trace_messages fields.
5157 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
5158 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
5159 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
5160 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
5161 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
5162 (m4_is_debug_bit): New macro to simplfy checks against the debug
5164 (m4_trace_format, m4_trace_header, m4_trace_flush)
5165 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
5167 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
5168 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
5169 * m4/macro.c (trace_format, trace_header, trace_flush)
5170 (trace_prepre, trace_pre, trace_post): ...to these newly static
5171 functions, since they are only ever used from this file. Changed
5174 2003-07-17 Gary V. Vaughan <gary@gnu.org>
5176 Change the macros for checking syntax so that matching against
5177 multiple possible syntax classes can be done with a single
5178 comparison some of the time. The various classes are now bits of
5179 an int that can be checked with bitwise logic operators.
5181 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
5182 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
5183 (M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)

5185 (M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)
5186 (M4_SYNTAX_ECOMM): Replaced #defines with an enum.
5187 (M4_SYNTAX_ALNUM): Removed. Changed all callers.
5188 (M4_IS_IGNORE, M4_IS_OTHER, M4_IS_SPACE, M4_IS_OPEN, M4_IS_CLOSE)
5189 (M4_IS_COMMA, M4_IS_DOLLAR, M4_IS_ACTIVE, M4_IS_ESCAPE)
5190 (M4_IS_ASSIGN, M4_IS_ALPHA, M4_IS_NUM, M4_IS_LQUOTE, M4_IS_RQUOTE)
5191 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
5192 Replace all calls with invocations of these...
5193 (m4_is_syntax, m4_has_syntax): ...New macros.
5194 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
5195 is no longer required with new macros. Changed all callers.
5197 2003-07-15 Gary V. Vaughan <gary@gnu.org>
5199 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
5200 values are returned as part of the internal interface, so they
5202 * m4/private.h: ...to here.
5203 * m4/macro.c (expand_token): Check for out of range
5204 m4_peek_input() results before looking up in the syntax table.
5205 (collect_arguments): Ditto.
5207 * NEWS: Note `$' syntax class.
5209 2003-07-08 Paul Eggert <eggert@twinsun.com> and
5210 Gary V. Vaughan <gary@gnu.org>
5212 Conform to POSIX if the POSIXLY_CORRECT environment is set.
5213 --traditional `define' now smashes all the definitions.
5215 * NEWS: Explain this.
5216 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
5217 (Extensions): Explain that extensions that are incompatible with
5218 POSIX are disabled if POSIXLY_CORRECT is set.
5219 (Incompatibilities): Remove.
5220 (Define, Other Incompat): Explain difference
5221 between GNU and POSIX behavior of define, pushdef, popdef.
5222 * m4/m4.c (m4_get_posixly_correct_opt): New undef.
5223 * m4/m4module.h (m4_context_opt_bit_table): Add POSIXLY_CORRECT entry.
5224 * m4/m4private.h (M4_OPT_POSIXLY_CORRECT_BIT): New macro.

5226 * m4/m4macro.c (m4_process_macro): Disable $10, $abc etc. if
5228 * modules/m4.c (builtin_functions): defn now takes any number of args.
5229 (builtin_define): Smash all the definitions if
5231 (builtin_defn)): Allow any number of arguments.
5232 (builtin_undivert): Do not allow nonnumeric arguments
5234 * src/main.c (main): Set posixly-correct behavior if either
5235 POSIXLY_CORRECT is set, or if -G is given.
5236 * tests/builtins.at: New test for smashed definitions.
5238 2003-06-27 Gary V. Vaughan <gary@gnu.org>
5240 * doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
5241 * m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
5242 not to slow the parser down.
5243 (M4__IS_STRING): New macro to test string syntax class membership.
5244 * m4/syntax.c: Adjust docucomment.
5245 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
5246 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
5247 * m4/input.c (init_builtin_token): Comment typo.
5248 (m4__next_token): Comment typo.
5249 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
5250 by using the new M4__IS_STRING macro.
5251 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
5252 variable references in macro expansions.
5254 * doc/m4.texinfo (Eregexp and Regexp): Typo.
5255 (Epatsubst and Patsubst): Typo.
5258 2003-06-26 Gary V. Vaughan <gary@gnu.org>
5260 Move the global variables that pertain to syntax to a new `struct
5261 m4_syntax_table', and then add one of these to `struct m4'. The
5262 ripple effect through the code to both change formerly global
5263 references, and make sure a suitable context is available in
5264 lexical scope is disproportionately large compared to the size of
5265 the change proper. This change is a large part of decoupling
5266 syntax.c from the rest of the code that uses it.
5268 * m4/m4private.h (struct m4): Add a syntax field.
5269 * m4/m4.c (m4_create): Initialise it,
5270 (m4_delete): Recycle it.
5271 (m4_get_symtab): Remove hand coded version...
5272 (m4_get_symbol_table): ...and generate this with cpp. Changed all
5274 * m4/m4module.h (m4_context_field_table): Add an extra field so we
5275 can generate m4_get_symbol_table. Add a new row for
5276 m4_get_syntax_table.
5277 (M4SYNTAX): Syntactic sugar for module writers.
5278 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
5279 (m4_syntax_table): New home for syntax related formerly global
5281 * m4/m4private.h (struct m4_syntax_table): Define it.
5282 * m4/input.c (m4_input_init): Initialisation of these formerly
5283 global variables moved...
5284 * m4/syntax.c (m4_syntax_create): ...to here.
5285 * m4/input.c (m4_input_exit): And similarly, recycling of the
5286 memory used by those values moved...
5287 * m4/syntax.c (m4_syntax_delete): ...to here.
5288 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
5289 Moved to m4/m4private.h.
5290 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
5291 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
5292 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
5293 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
5294 objects. Changed all callers that used to directly access the
5296 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
5297 Removed and incorporated into m4_syntax_table structure.
5298 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
5299 * m4/syntax.c (m4_set_syntax): Now returns an error status,
5300 instead of requiring a `struct m4' to generate its own errors.
5301 Changed all callers.
5302 * src/main.c (main): Now that the syntax table is initialised as
5303 part of m4_create, we have to manually wipe the syntax entries if
5304 we are about to read a frozen file.
5306 2003-06-26 Gary V. Vaughan <gary@gnu.org>
5308 * doc/STYLE: Added notes on callback naming schemes.
5310 * m4/module.c (m4_set_module_macro_table)
5311 (m4_set_module_builtin_table): Declarations weren't changed when
5312 definitions were renamed on 2003-06-19.
5314 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
5315 neither used nor particularly appropriate since it exposes the
5316 internal workings of the hash module. I haven't yet decided
5317 whether to remove it entirely.
5319 2003-06-20 Gary V. Vaughan <gary@gnu.org>
5321 Two related changes, and a huge knockon effect throughout the
5322 source: Moved the option variables out of global space and into
5323 `struct m4'; made `m4_symtab' a real datatype, so that its api
5324 is not marred passing `struct m4' around just so it can decide
5325 whether to keep traced symbol names or not. Added setters and
5326 getters for the formerly global option variables, and obviously
5327 changed a vast number of functions to take a `struct m4' and use
5328 the getter funcs to find option values.
5330 * m4/utility.c (interactive, sync_output, debug_level)
5331 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
5332 (max_debug_argument_length, warning_status, nesting_limit)
5333 (discard_comments): Removed.
5334 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
5335 (debug_level, max_debug_argument_length, prefix_all_builtins)
5336 (suppress_warnings, discard_comments, interactive, sync_output):
5337 Removed from here...
5338 * m4/m4private.h (struct m4): ...and equivalent fields added to
5340 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
5341 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
5342 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
5343 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
5344 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
5345 macros for the new fields.
5346 * m4/m4module.h (m4_context_field_table)
5347 (m4_context_opt_bit_table): Helper macros used to generate
5348 prototypes, setters and getters for new option fields
5350 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
5351 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
5352 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
5353 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
5354 (m4_get_interactive_opt, m4_get_sync_output_opt)
5355 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
5356 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
5357 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
5358 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
5359 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
5360 setter and getter functions generated by cpp from
5361 m4_context_field_table and m4_context_opt_bit_table, exported as
5362 part of the module api. Changed all callers.
5363 * m4/symtab (struct m4_symtab): Used as the concrete type for
5365 (m4_symtab_create): Allocate and initialise a new struct.
5366 (m4_symtab_apply): New function that works like m4_hash_apply, but
5367 with different callbacks specific to symbol tables. Changed all
5369 (symbol_destroy, arg_destroy, arg_copy): Renamed
5370 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
5371 they have unused parameters for a reason!
5372 (dump_symbol_CB): New callback to dump the contents of a single
5374 (symtob_dump): Rewritten in terms of dump_symbol_CB.
5375 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
5376 Changed all callers.
5377 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
5378 of the contained `m4_symtab' at the `no_gnu_extensions' field.
5379 Although I'm not convinced these semantics are correct, they are
5380 at least consistent with how things were before this delta. Also
5381 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
5383 2003-06-19 Gary V. Vaughan <gary@gnu.org>
5385 Tie down the interface to libm4 some more. Make more structures
5386 opaque to modules by moving them to m4private.h, and writing
5387 setters and getters. To win back the speed penalty for doing this
5388 also wrote macroized versions that do know about structure layout
5389 in m4private.h and #include that file into modules when NDEBUG is
5390 defined at compile time. There are still some accessor macros in
5391 m4private.h that need to go, but that is not necessary to clean
5394 * m4/m4module.h (m4_symbol_type): Moved...
5395 * m4/m4private.h (m4__symbol_type): ...to here.
5396 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
5397 (m4_set_symbol_traced, m4_set_symbol_name_traced)
5398 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
5399 (m4_get_symbol_func, m4_symbol_value_create)
5400 (m4_symbol_value_delete, m4_set_symbol_value_text)
5401 (m4_set_symbol_value_func): New exported api to symbols.
5402 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
5403 and m4_is_symbol_value_func.
5404 * m4/m4module.h: Prototype these guys.
5405 * m4/module.c (m4_set_module_macro_table)
5406 (m4_set_module_builtin_table): Make these static, there is no
5407 reason to pollute the api with them.
5408 * m4/m4private.h: Reformatting.
5409 (m4_get_symtab): Only define when NDEBUG is defined.
5410 (m4_get_symbol_value, m4_get_symbol_traced)
5411 (m4_set_symbol_traced, m4_set_symbol_name_traced)
5412 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
5413 (m4_get_symbol_func, m4_symbol_value_create)
5414 (m4_symbol_value_delete, m4_set_symbol_value_text)
5415 (m4_set_symbol_value_func): Macro implementations of the new
5416 functions when NDEBUG is defined.
5417 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
5418 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
5419 Superceded by the above. All callers changed.
5420 (M4ARG): Removed. This is no longer different to the
5421 m4/m4module.h definition.
5422 * modules/gnu.c, modules/m4.c: Only include m4private.h when
5423 NDEBUG is defined. That way we exercise the same (albeit slower)
5424 api that external modules must use.
5426 2003-06-18 Gary V. Vaughan <gary@gnu.org>
5428 Renamed some of the types and their accessors to make more sense.
5429 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
5430 has a stack of SYMBOL_VALUEs.
5432 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
5433 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
5434 m4_get_symbol_value_type, m4_get_symbol_value_text,
5435 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
5436 Changed all callers.
5437 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
5438 (m4_get_token_type): Renamed
5439 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
5440 to the internal api.
5441 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
5443 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
5444 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
5445 (m4__token_type): Moved here from m4module.h.
5446 (m4__next_token): Renamed from m4_next_token.
5447 * m4/symtab.c: Removed some of the parameterised macro support
5448 functions for modularisation later.
5449 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
5450 m4_hash_dup to perform a true deep copy of the SRC.
5451 (arg_copy): Callback for m4_symbol_value_copy.
5452 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
5453 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
5454 m4_get_symbol_value_func. Changed all callers.
5456 2003-06-18 Gary V. Vaughan <gary@gnu.org>
5458 Tidy up style of hash.[ch] in accordance with doc/STYLE.
5460 * m4/hash.c: Internal symbol renaming and formatting.
5461 (m4_hash_dup): New function to facilitate deep copies of hash
5463 (m4_hash_apply_func): Returns a void* now, which is a richer type
5464 for returning exceptions (NULL means keep going).
5465 (m4_hash_apply): Ditto.
5466 * m4/hash.h: Declare exported symbols with an explicit extern.
5469 2003-06-17 Gary V. Vaughan <gary@gnu.org>
5471 Still refactoring furiously. This delta represents a change in
5472 semantics to symtab.c. Instead of building temporary m4_tokens
5473 in the caller, and copying fields in the methods, we now create
5474 the actual m4_token for hashing in the caller so the methods just
5475 slot them in directly. Also, this means that we don't lookup a
5476 symbol and get back an allocated but VOID token to copy fields
5477 into, we create the token we want to push and pass that to
5478 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
5479 a few other small changes to stop knowledge of the implementation
5480 of symtab.c leaking out into other files.
5482 * m4/macro.c (expand_argument): Comment typo corrected.
5483 * m4/symtab.c (symtab_fetch): New function to fetch the address of
5485 (m4_symbol_pushdef): Take an extra value parameter and use this
5486 directly as the new top of the value stack. All callers changed
5487 to build a token and pass responsibility for memory in, rather
5488 than copying as we used to.
5489 (m4_symbol_define): Also use the new value parameter directly as a
5490 replacement for the top of the value stack. All callers changed
5491 to build a token as above.
5492 (m4_set_symbol_traced): New function to set the traced bit on the
5493 named symbol, creating it if necessary.
5494 (symbol_popval): The guts of the old m4_symbol_popdef.
5495 (m4_symbol_popdef): Use it.
5496 * m4/builtin.c (m4_symbol_set_token): Removed,
5497 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
5499 * m4/module.c (m4_set_module_builtin_table)
5500 (m4_set_module_macro_table): ...with these more orthogonal
5502 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
5503 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
5505 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
5506 (m4_arg_signature_parse): Moved...
5507 * m4/symtab.c: ...to here.
5508 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
5509 screw something up. Moved...
5510 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
5511 actually does a proper deep copy of source to dest.
5513 2003-06-16 Gary V. Vaughan <gary@gnu.org>
5515 Further refactoring to stabilise the module API. Renaming some
5516 functions for orthogonality, and judicious definition migration to
5517 move things out of the set of exported symbols.
5519 * doc/STYLE: New file. Notes on coding style.
5520 * m4/m4module.c: Updated bitrotted docucomment at the top of the
5522 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
5523 m4_get_module_name, m4_get_module_builtin_table,
5524 m4_get_module_macro_table which are verb phrases. Changed all
5526 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
5528 * m4/module.c (m4_set_module_builtin_table)
5529 (m4_set_module_macro_table): ...here, and renamed. Changed all
5531 * m4/m4module.c (m4_module_data): This...
5532 * m4/m4private.c (struct m4_module_data): ...and this...
5533 * m4/module.c (module_data) ...consolidated here and no longer
5534 exported. Changed all callers.
5536 2003-06-16 Gary V. Vaughan <gary@gnu.org>
5538 Begin work on lifting the curse of the global variables. To start
5539 with create a `struct m4' context container, and replace
5540 `m4__symtab' with `context->symtab' throughout. This means
5541 initialising a context container in main, and adjusting many
5542 functions between main and the module entry points so that the
5543 container gets passed through. It would have been nice to
5544 defer this until after 1.5, but it has a major effect on the
5545 user's module writing ABI, so it needs to be addressed now - at
5546 least in the areas that impact the ABI. An interrelated change
5547 in the symtab API removes the dependency on a global symbol table,
5548 and instead focuses on a passed table (from the context
5551 * TODO: Reminders for finishing context functionality.
5552 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
5553 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
5554 global variables and eventually allow m4 to be reentrant.
5555 * m4/m4private.h (m4): Define the new structure here...
5556 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
5557 don't carry the overhead of a function call.
5558 * m4/m4module.h: Prototype extern functions from m4/m4.c.
5559 (m4): Declare type for new struct m4 objects.
5560 (M4SYMTAB): User macro to ease finding the symbol table for the
5561 current context for module developers.
5562 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
5564 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
5565 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
5566 (m4_call_macro, m4_dump_symbols, m4_expand_input)
5567 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
5568 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
5569 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
5570 m4* context parameter. Changed definitions and all callers.
5571 (m4_symtab): Alias for m4_hash to decouple the
5572 m4_symtab api from m4_hash.
5573 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
5575 (m4_symtab_create): New function to return an initialised
5577 (m4_symtab_delete): New function to delete an m4_symtab's memory.
5578 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
5579 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
5580 instead of simply using the global m4__symtab. Changed
5581 definitions and all callers.
5582 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
5583 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
5584 * src/main.c (main): Create a context and use that instead of the
5585 former global m4__symtab.
5587 2003-06-13 Gary V. Vaughan <gary@gnu.org>
5589 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
5590 to the callback. Callbacks should not need to hardcode the
5591 hashtable they are working from, nor should we have to waste the
5592 userdata parameter to pass the table in.
5593 * m4/hash.h (m4_hash_apply_func): Require the initial table
5595 * m4/symtab.c (symtab_destroy): Use the passed table instead
5596 of hardcoding m4__symtab.
5597 (m4_symbol_popdef): Don't use the userdata parameter to pass the
5598 table to arg_destroy.
5599 (arg_destroy): Use the hash parameter, ignore userdata.
5600 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
5602 (traceon, traceoff): Call set_trace with the extra initial
5605 2003-06-13 Gary V. Vaughan <gary@gnu.org>
5607 More refactoring to stabilise the module api, this time for
5608 symtab.c. Additionally, start to pay attention to function names
5609 that don't contain a verb like they should.
5611 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
5612 wrapper for m4_hash_apply to decouple the symtab module from the
5614 (m4_symbol_builtin, m4_symbol_macro): Renamed to
5615 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
5617 (m4_symbol_delete): Create a macro version to save a function
5619 (m4_token_t, m4_data_t): These violate the POSIX reserved
5620 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
5622 (m4_token_type): Renamed to m4_token_get_type.
5623 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
5624 (m4_symtab_exit): Removed from the exported module
5626 * m4/m4private.h (m4__symtab, m4__symtab_init)
5627 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
5628 renamed and added to the internal api. Changed all callers.
5629 (m4_symtab_apply): A faster macro version of the function for
5630 users of the internal api.
5631 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
5632 symbol_destroy and arg_destroy.
5633 (symtab_debug): Added a prototype.
5634 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
5635 so that callers in this file get the faster macro versions from
5638 2003-06-12 Gary V. Vaughan <gary@gnu.org>
5640 Refactoring modules to rationalise the API into an external
5641 documented (eventually!) API for use by modules in the `m4_'
5642 namespace declared in m4/m4module.h, an internal API between the
5643 source files we ship (including our shipped modules) in the `m4__'
5644 namespace declared in m4/m4private.h and making the rest as
5645 cohesive as possible with liberal use of the `static' keyword.
5646 This change represents an audit to m4/module.c along these
5649 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
5650 Removed. No longer used.
5651 (m4_module_close): Removed prototypes.
5652 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
5653 from the exported module api...
5654 * m4/m4private.h (m4__module_init, m4__module_open)
5655 (m4__module_exit): ...and renamed and added to the internal api.
5656 Changed all callers.
5657 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
5658 Centralised definitions after renaming...
5659 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
5660 (M4_FINISH_SYMBOL): ...and removing from here.
5661 (m4_module_dlerror, m4_module_remove, m4_module_close)
5662 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
5663 module_remove, module_close and caller_id.
5664 (MODULE_SELF_NAME): New macro to make reporting self errors
5666 (m4_module_load, module_close, module_remove): Use it.
5667 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
5669 * src/main.c (main): Use it.
5671 2003-06-12 Gary V. Vaughan <gary@gnu.org>
5673 * README: Remove references to --enable-changeword, which has been
5674 removed from the code.
5676 2003-06-11 Gary V. Vaughan <gary@gnu.org>
5678 Getting rid of the annoying bug with configure --enable-debug,
5679 which spewed -e: command not found errors. This was an interaction
5680 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
5681 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
5682 branch-1-5) to get the full fix.
5684 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
5685 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
5686 and then use the probed value of $SED.
5687 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
5688 this, it messes up the AC_REQUIRE stack.
5690 2003-06-10 Gary V. Vaughan <gary@gnu.org>
5692 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
5693 the destroy callback.
5694 (m4_arg_destroy): Use the hash address to free the hash node key
5697 2003-06-06 Gary V. Vaughan <gary@gnu.org>
5699 First cut at formal parameters in macros.
5701 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
5702 * m4/xstrzdup.c: New file.
5703 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
5704 associative array of parameter names to details.
5705 (m4_symbol_token): Capture macro names with parameter lists.
5706 (m4_arg_signature_parse): And build an associative array to hang
5707 from the symbol structure to map names to details.
5708 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
5709 m4_hash_resize idiom. Now that we potentially add a little hash
5710 table to many of the entries in the symbol table, added an extra
5711 arg to set the initial size. Changed all callers.
5712 (m4_hash_apply): New function that is basically a generalised
5714 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
5715 all callers to call m4_hash_apply instead.
5716 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
5717 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
5718 m4_arg_signature association that might be attached to the symbol,
5719 * m4/hash.h (m4_hash_apply_func): Replacement type for...
5720 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
5721 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
5723 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
5724 (M4_IS_IDENT): Detect characters that can be safely used in
5726 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
5727 * m4/macro.c: Corrected grammar in some comments. Use `token'
5728 rather than `td' for m4_token variables.
5729 (m4_process_macro): If we find a dollar followed by some
5730 M4_IS_IDENT characters, replace that with the contents of the argv
5731 entry with offset stored in the m4_token_arg associated with the
5732 collected identifier.
5734 2003-06-05 Gary V. Vaughan <gary@gnu.org>
5736 Begin preparations for supporting formal parameters in m4 macros.
5738 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
5739 the details of a formal parameter.
5740 (m4_token): Add an arg_signature member to hold a hash table for
5741 looking up formal parameters.
5742 * m4/input.c: Update more bitrotted comments.
5743 (m4_push_builtin): Initialise arg_signature member.
5744 (init_builtin_token): Copy arg_signature member.
5745 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
5746 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
5748 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
5749 (m4_macro_pushdef, m4_macro_define): ...these, And...
5750 (m4_symbol_token): ...wrapped around this new function, which
5751 vastly simplifies the arguments required by the functions it
5753 Changed all callers.
5755 2003-06-05 Gary V. Vaughan <gary@gnu.org>
5757 * m4/macro.c: Format changes.
5759 2003-06-04 Gary V. Vaughan <gary@gnu.org>
5761 * m4/input.c: Updated various bitrotted comments.
5762 (m4_push_builtin): Just pass the whole m4_token, rather than
5763 extracting all the fields in the caller. This also allows us to
5764 check the token type for consistency.
5765 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
5766 Renamed to builtin_funcs, builtin_peek, builtin_read,
5767 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
5768 the code. Changed all callers.
5769 (struct input_block): Similarly renamed u_m member to u_b, and
5770 changed all callers.
5771 (m4_next_token): Use bzero to initialise the data fields.
5772 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
5774 2003-05-29 Gary V. Vaughan <gary@gnu.org>
5776 These changes were necessary to get m4 to build on my iBook
5777 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
5778 (GCC) 3.1 20020420 (prerelease)":
5780 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
5781 inclusion of module loader headers.
5782 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
5783 * m4/Makefile.am: Ditto.
5784 (libm4_la_LIBADD): Added $(LTLIBINTL).
5785 * m4/utility.c (program_name): Removed declaration in favour of
5786 the one already in error.c!
5787 * m4/m4module.h (program_name): Define to program_invocation_name
5788 when using GNU C library. Use an explicit extern declaration.

5799 (m4_current_line, m4_current_diversion, m4_output_current_line):
5800 Don't rely on default, use an explicit extern.
5801 * m4/error.h (error, error_at_line, error_print_progname)
5802 (error_message_count, error_one_per_line): Ditto.
5803 * m4/ltdl.c: Update from CVS libtool.

5820 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
5822 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
5824 2002-11-04 Akim Demaille <akim@epita.fr>
5826 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
5828 2002-11-04 Akim Demaille <akim@epita.fr>
5830 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
5831 used as `external', and Libtool 1.4.3.
5833 (LTLIBOBJS): Don't play with it.
5835 * Makefile.am (SUBDIRS): Remove intl.
5836 (ACLOCAL_AMFLAGS): Add -I config.
5837 (EXTRA_DIST): Add config/config.rpath.
5840 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
5842 2002-05-29 Gary V. Vaughan <gary@gnu.org>
5844 Preparations for refactoring syntax tables to allow reverse
5845 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
5846 speed of normal lookups in an array of unsigned short.
5848 * m4/input.c (single_quotes, single_comments, use_macro_escape):
5850 * m4/m4private.h (m4__single_quotes, m4__single_comments,
5851 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
5852 is for internal symbols which unavoidably pollute the global
5853 namespace, but are not published APIs.
5854 Adjusted all callers.
5855 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
5856 m4_set_comment, m4_set_syntax, set_syntax_internal,
5857 unset_syntax_attribute): Moved from this file...
5858 * m4/syntax.c: New. ...to this file.
5859 Also added an m4_syntax_exit stub for orthogonality.
5860 * src/main.c (main): Use it.
5861 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
5862 * m4/m4module.h: Reformatting. New prototypes.
5864 2002-05-29 Gary V. Vaughan <gary@gnu.org>
5866 * bootstrap (aclocal_apiversion): The aclocal apiversion is
5867 distinct from the automake release number (in that the apiversion
5868 apparently has no micro-version-component).
5869 (aclocal_apilibdir): Use it.
5871 2002-05-28 Gary V. Vaughan <gary@gnu.org>
5873 * m4/hash.c (m4_hash_resize): New function.
5874 * m4/hash.h: Add prototype.
5875 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
5876 benchmarking to find a good value for, say, autoconf. This is
5877 already a little quicker than before for me.
5879 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
5880 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
5882 * m4/hash.h: Adjust prototypes.
5884 2002-01-22 Akim Demaille <akim@epita.fr>
5886 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
5888 * tests/Makefile.am (package.m4): New.
5889 * tests/atlocal.in: Adjust to CVS Autotest.
5890 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
5891 * configure.ac: LIBOBJ is a forbidden string.
5892 Simplify AM_INIT_AUTOMAKE invocation.
5893 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
5896 2002-01-21 gettextize <bug-gnu-utils@gnu.org>

5918 2001-10-17 Gary V. Vaughan <gary@gnu.org>
5920 * bootstrap: s/configure.in/configure.ac/
5922 2001-10-16 Gary V. Vaughan <gary@gnu.org>
5924 * m4/symtab.c (m4_symbol_destroy): This function calls
5925 m4_symbol_popdef, which recycles a symbols memory when the last
5926 definition is popped. Since we were passing the address of the
5927 symbol name found in the symbol table, and it was being removed
5928 partway through m4_symbol_destroy() we were referencing freed
5929 memory for the balance of the function. Now we take a copy of the
5930 symbol name tring and use that as a key into the symbol
5931 table... that way if the original symbol name is freed, the copy
5934 2001-10-13 Akim Demaille <akim@epita.fr>
5936 * m4/ltdl.c: Update.
5938 2001-10-13 Akim Demaille <akim@epita.fr>
5940 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
5941 Don't gettextize internal error messages.
5943 2001-10-13 Akim Demaille <akim@epita.fr>
5945 * tests/macros.at (Arity and defn): New failing test.
5946 (Arity, defn, and freeze): New.
5948 Fix `Arity and defn'.
5950 * m4/input.c (m4_push_macro): Don't forget the arity.
5951 * modules/m4.c (defn): Likewise.
5953 2001-10-13 Akim Demaille <akim@epita.fr>
5955 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
5957 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
5958 (Propagation of traceon, Propagation of --trace): this new file.
5960 2001-10-13 Akim Demaille <akim@epita.fr>
5962 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
5963 interface instead of (name, argc...).
5964 Upon failure, specify which argument was guilty.
5967 2001-10-13 Akim Demaille <akim@epita.fr>
5969 * modules/evalparse.c: Save translators' time: don't translate
5970 internal error messages.
5971 (m4_evaluate): Simplify/normalize error messages.
5972 * doc/m4.texinfo (Eval): Adjust.
5974 2001-10-13 Akim Demaille <akim@epita.fr>
5976 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
5977 where no checking is needed.
5978 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
5979 interface instead of (name, argc...).
5981 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
5984 2001-10-13 Akim Demaille <akim@epita.fr>
5986 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
5987 exclude the builtin name from the count.
5988 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
5989 calling ifelse with a single argument is valid.
5990 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
5991 with 1 and 2 args, mostly to strengthen the test suite.
5993 2001-10-13 Akim Demaille <akim@epita.fr>
5995 * m4/output.c (m4_make_diversion, m4_insert_file)
5996 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
5998 2001-10-12 Gary V. Vaughan <gary@gnu.org>
6000 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
6001 since we call these things builtins in the rest of the code!
6003 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
6005 2001-10-12 Gary V. Vaughan <gary@gnu.org>
6007 Rather than forcing each builtin definition to manage its own
6008 argument range checking, tabulate the maxima and minima for all
6009 builtins in each module. This forces us to consider what the
6010 valid ranges for each builtin should be, and moves the checking
6011 code out of each builtin implementation and into the builtin
6012 caller infrastructure.
6014 * m4/m4module.h (struct m4_builtin): Add argument minima and
6016 * m4/m4private.h (struct m4_token): Reflect them here too.
6017 * m4/input.c (struct input_block): ...and here.
6018 (m4_token_copy): New function for token copying.
6019 (init_macro_token): Copy them from a token to the input stack.
6020 (m4_next_token): Don't forget to initialise them for text
6022 * m4/macro.c (expand_argument): Use m4_token_copy, and also
6023 check argument counts before calling the builtin handler.
6024 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
6025 (m4_symbol_macro): Likewise.
6026 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
6027 parameters. Updated all callers.
6028 (m4_builtin_define): Ditto.
6029 (m4_macro_pushdef, m4_macro_define): Ditto.
6030 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
6031 * modules/evalparse.c: Declare argument counts for defined
6032 builtins and remove explicit calls to m4_bad_argc().
6033 * modules/gnu.c: Ditto.
6034 * modules/load.c: Ditto.
6035 * modules/m4.c: Ditto.
6036 * modules/modtest.c: Ditto.
6037 * modules/mpeval.c: Ditto.
6038 * modules/perl.c: Ditto.
6039 * modules/shadow.c: Ditto.
6040 * modules/stdlib.c: Ditto.
6041 * modules/time.c: Ditto.
6044 2001-10-10 Gary V. Vaughan <gary@gnu.org>
6046 The trace semantics now attach the trace bit to a symbol name.
6047 For as long as a traceon(`foo') is active, calls to foo will be
6048 traced regardless of intervening undefines or module unloads.
6049 Fixed the flag propogation issues differently to the fixes
6050 reverted with the last attempt at nailing down trace:
6052 * m4/m4private.h: This file is not visible outside of the m4
6053 source tree, so I removed all the `M4_' and `m4_' prefixes to save
6054 on typing. Updated all clients.
6055 (m4_token): New typedef contains the fields that need to be passed
6056 around with the low level tokeniser.
6057 (m4_token_data): Removed.
6058 (m4_symbol): Now contains the traced flag again.
6059 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
6060 the trace bit set. This change is contained entirely within this
6061 module and doesn't leak out into the callers. Updated all
6063 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
6064 new fields in m4_token. Updated all clients.
6065 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
6066 that `groks_macro_args' and `blind_if_no_args' flags are retained
6067 when defn() results are passed around in m4 code. Updated all
6069 (m4_builtin_define): Ditto.
6070 (m4_macro_pushdef, m4_macro_define): Ditto.
6071 * m4/input.c (struct input_block): Add a flags field to facilitate
6073 (m4_push_macro): ...use it.
6074 (init_macro_token): Retrieve it.
6075 (m4_next_token): Initialise it.
6076 * m4/macro.c (expand_argument): Copy it.
6077 * m4/m4module.h: Adjust.
6078 * tests/builtins.at: Adjust the expected output of the trace
6079 tests to reflect the change in semantics.
6080 * tests/modules.at (modules: trace): Check that unloading a
6081 module which supplies a traced symbol definition doesn't lose te
6084 2001-10-07 Gary V. Vaughan <gary@gnu.org>
6086 * modules/gnu.c (m4_macro_table): Display the timetamp when
6087 expanding __m4_version__.
6089 * configure.ac (--with-modules): Forgot a comma in the
6090 AC_HELP_STRING parameter list.
6092 2001-10-05 Gary V. Vaughan <gary@gnu.org>
6094 * bootstrap: Remove aclocal.m4t when it is no longer required.
6096 2001-10-05 Akim Demaille <akim@epita.fr>
6098 * tests/Makefile.am: Adjust for gnuprog2.
6099 * tests/m4.in: There can be a leading path.
6100 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
6101 * tests/testsuite.at: Adjust to the most recent Autotest.
6102 (AT_CHECK_M4_FILTER): Fix and rename as...
6104 * tests/others.at: Use it.
6106 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
6107 variable in shell scripts, one uses `$'...
6109 2001-10-04 Gary V. Vaughan <gary@gnu.org>
6111 * configure.ac: `rm -f $m4_getopt_h' was lost.
6113 2001-10-04 Gary V. Vaughan <gary@gnu.org>
6115 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
6116 time. Define it for config.h in order to...
6117 * src/main.c (main): ...display the timestamp for --version.
6119 2001-10-04 Akim Demaille <akim@epita.fr>
6121 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
6122 previous builtins `regexp' and `patsubst'.
6123 (regexp, patsubst): Use them.
6124 (eregexp, epatsubst): New builtins.
6125 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
6126 (Epatsubst and Patsubst, Eregexp and Regexp): these.
6127 (Extensions): More info on REs.
6129 2001-10-04 Akim Demaille <akim@epita.fr>
6131 * modules/modtest.c (init_handler): Consistently output to stderr.
6132 (finish_handler): New.
6133 (test): The `if' is an `assert'.
6134 * tests/modules.at: Adjust.
6136 2001-10-04 Akim Demaille <akim@epita.fr>
6138 * m4/utility.c (m4_bad_argc): Detail the mismatches.
6140 2001-10-01 Akim Demaille <akim@epita.fr>
6142 * tests/generate.awk: Tag the tests with `documentation'.
6143 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
6144 Use the make the existing modtest tests more uniform, and complete
6145 the set of possibilities.
6147 2001-10-01 Akim Demaille <akim@epita.fr>
6149 * config/gmp.m4: Consult the user before using GMP: use
6151 * configure.ac: Adjust.
6152 * modules/gmp.c: No protection needed as the module is not built
6155 2001-10-01 Akim Demaille <akim@epita.fr>
6157 * tests/generate.awk: Remove debugging code.
6158 (fatal): Specify the current location.
6160 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
6161 * modules/gnu.c, modules/m4.c: Use M4ARG.
6163 2001-10-01 Akim Demaille <akim@epita.fr>
6165 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
6166 (m4_regexp_compile): New.
6167 (regexp, patsubst): Use it.
6169 2001-09-30 Gary V. Vaughan <gary@gnu.org>
6171 Reinstate the memory handling improvements from the patch I just
6172 reverted. Relevant ChangeLog entries repeated here:
6174 * m4/module.c (m4_module_remove): New function that holds the core
6175 of the old m4_module_unload.
6176 (m4_module_unload): Use it.
6177 (m4_module_unload_all): When we know the modules will never be
6178 used again (i.e. on exit), free up as much module memory as
6179 possible. There are still some artifacts from resident modules
6180 living inside ltdl.c, but everything else is freed.
6181 * m4/debug.c (m4_debug_exit): Free memory allocated in
6183 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
6184 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
6185 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
6186 * m4/m4module.h: Updated prototypes.
6187 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
6188 * m4/hash.h: Updated prototypes.
6189 * src/main.c (main): Use all these new functions to clean up as
6190 much memory as possible before exit.
6192 2001-09-30 Gary V. Vaughan <gary@gnu.org>
6194 Reverted my large patch for removing the old m4_symbol
6195 structure on 2001-09-20. We are still not happy about the way
6196 trace works in conjunction with defn and undefine, and leaving
6197 the reverted patch active prevents us from moving the traced
6198 bit from the definition back to the symbol.
6200 2001-09-30 Gary V. Vaughan <gary@gnu.org>
6202 * configure.in: Moved to...
6203 * configure.ac: ...here. Added a libtool like timestamped
6204 banner, and tidied up the libltdl cruft.
6205 * config/mkstamp: Script to extract a timestamp from ChangeLog.
6206 * modules/Makefile.am (INCLTDL): Removed. This is required
6207 only when libltdl is configured in a subdirectory.
6208 * src/Makefile.am: Ditto.
6209 (LIBADD_DL): No need to add this again, libtool already knows
6210 that libm4.la depends on it.
6211 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
6214 * TODO: stackovf.c is basically broken.
6215 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
6217 2001-09-28 Akim Demaille <akim@epita.fr>
6219 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
6221 2001-09-27 Akim Demaille <akim@epita.fr>
6223 * tests/m4.in: Don't use short options.
6224 Simplify the stderr signature normalization.
6226 2001-09-27 Akim Demaille <akim@epita.fr>
6228 tests/m4 shall be position independent.
6232 * tests/testsuite.at: No args to AT_INIT.
6233 * configure.in, tests/Makefile.am: Adjust.
6235 2001-09-22 Akim Demaille <akim@epita.fr>
6237 Autotest has changed again.
6239 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
6240 (package.m4): Remove.
6241 * configure.in: Adjust to LIBADD_GMP.
6243 2001-09-21 Gary V. Vaughan <gary@gnu.org>
6245 * config/gmp.m4 (AC_ARG_WITH): Removed.
6246 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
6247 (AC_LIB_GMP): When performing a test compile against libgmp,
6248 include the header gmp.h if possible, and link against -lgmp. If
6249 they both work define USE_GMP.
6250 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
6251 (mpeval_LTX_init_func): Complain on load that there was no libgmp
6254 2001-09-20 Gary V. Vaughan <gary@gnu.org>
6256 * m4/evalparse.c: Moved to...
6257 * modules/evalparse.c: ...here. This code is shared between
6258 modules/mpeval.c and modules/m4.c, so there is no need to pollute
6259 the libm4 API with its details. Moderately rewritten to interface
6260 into its clients more simply.
6261 * m4/eval.c: Deleted. Migrated functionality to...
6262 * modules/m4.c: ...here.
6263 (builtin_eval): Implemented in terms of the new interface style.
6264 * modules/mpeval.c (builtin_mpeval): Ditto.
6265 * m4/m4module.h: Removed references to the former m4/eval.c.
6266 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
6267 (EXTRA_libm4_la_SOURCES): Deleted.
6268 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
6269 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
6271 2001-09-20 Akim Demaille <akim@epita.fr>
6273 * config/gmp.m4 (AM_WITH_GMP): Rename as...
6275 By default, use gmp.
6277 * configure.in: Adjust.
6278 Use Automake conditionals for USE_GMP.
6279 Always compute sizeof (long long int).
6280 This was a bug BTW, as `eval' (not `mpeval') depends on it:
6281 before, it was used _only_ if mpeval was not activated.
6282 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
6283 (mpeval_la_LIBADD): New macros.
6284 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
6286 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
6287 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
6290 2001-09-20 Akim Demaille <akim@epita.fr>
6292 * tests/Makefile.am (package.m4): New.
6293 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
6295 2001-09-20 Gary V. Vaughan <gary@gnu.org>
6297 More cleanup. After the last patch, m4_symbol holds nothing but
6298 the head of a chain of m4_token_data. So I have removed the old
6299 m4_symbol, so that m4_token_data chains are stored directly in the
6300 value cell of a hash table node. But there's more... m4_symbol
6301 was a more natural name for the symbol value cell, and now that it
6302 is gone I have renamed the former m4_token_data structure to
6303 m4_symbol. This change turned out to be a pig to get right, since
6304 the original code didn't need to modify the value cell itself,
6305 since changing the chain happened inside the m4_symbol that used
6306 to be returned -- I had to pass the address of the value cell
6307 across various function calls, incase the head value changed. I
6308 also tightened up the memory management to help me find a nasty
6309 memory corruption bug that took me all night to track down...
6311 * m4/m4private.h (struct m4_symbol): Removed.
6312 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
6314 * m4/hash.c (m4_hash_iterator_value): Return the address of the
6315 value cell. Updated all callers.
6316 * m4/symtab.c: Took advantage of the simplification in the data
6317 structures to rewrite a lot of this file more simply. There is
6318 still some room for optimisation here, but we should tackle that
6319 systematically closer to the release.
6321 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
6322 revealed. This version is ahead of CVS libtool until I get chance
6323 to flush my changes.
6324 * m4/module.c (m4_module_remove): New function that holds the core
6325 of the old m4_module_unload.
6326 (m4_module_unload): Use it.
6327 (m4_module_unload_all): When we know the modules will never be
6328 used again (i.e. on exit), free up as much module memory as
6329 possible. There are still some artifacts from resident modules
6330 living inside ltdl.c, but everything else is freed.
6331 * m4/debug.c (m4_debug_exit): Free memory allocated in
6333 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
6334 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
6335 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
6336 * m4/m4module.h: Updated prototypes.
6337 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
6338 * m4/hash.h: Updated prototypes.
6339 * src/main.c (main): Use all these new functions to clean up as
6340 much memory as possible before exit.
6342 2001-09-18 Gary V. Vaughan <gary@gnu.org>
6344 The `traced' flag needs to be attached to the definition of a
6345 symbol rather than the current symbol containing the definition.
6346 Implementing this showed up some long standing post 1.4 bugs in
6347 flag propogation which I also fixed.
6349 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
6350 (struct m4_token_data): And add it back in here.
6351 * m4/input.c (init_macro_token): Propogate the traced flag
6353 * m4/macro.c (expand_argument): Ditto.
6354 * tests/builtins.at (trace2, trace3): New tests based on Akim's
6357 2001-09-08 Gary V. Vaughan <gary@gnu.org>
6359 * m4/m4private.h (struct m4_token_data): Simplified by removing
6360 the redundant `traced' flag, and one level of structure nesting.
6361 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
6362 * m4/input.c (init_macro_token): No need to initialise removed
6364 * m4/macro.c (expand_argument): No need to copy it either.
6365 * m4/utility.c (m4_token_data_func_traced): Or provide an access
6368 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
6369 dependant on multiple symbols with the same key, so preserving
6370 relative symbol order in each bucket during resizing is no longer
6371 required. The resize function is considerably faster as a result.
6373 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
6374 s/m4_symbol_insert/m4_symbol_define/g;
6375 s/m4_builtin_insert/m4_builtin_define/g;
6376 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
6378 2001-09-08 Gary V. Vaughan <gary@gnu.org>
6380 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
6381 commits, the m4_lookup_symbol dispatch function is split into
6382 specialised functions that must be called directly.
6384 * m4/m4module.h (m4_symbol_lookup_t): Removed.
6385 * m4/symtab.c (m4_lookup_symbol): Removed.
6386 (m4_symbol_builtin, m4_symbol_macro): New functions.
6387 * m4/builtin.c (m4_builtin_define): Split into...
6388 (m4_builtin_pushdef, m4_builtin_insert): ...these.
6389 (m4_macro_define): Split into...
6390 (m4_macro_pushdef, m4_macro_insert): ...these.
6391 * src/main.c (main): Set command line macros from `-D' parameters
6392 using `m4_macro_define'.
6394 2001-09-08 Gary V. Vaughan <gary@gnu.org>
6396 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
6397 this from m4_remove_table_reference_symbols().
6398 * m4/m4module.h, m4/module.c: Updated all references.
6400 2001-09-07 Akim Demaille <akim@epita.fr>
6402 * modules/stdlib.c, modules/times.c: Misc cleanups.
6404 2001-09-07 Akim Demaille <akim@epita.fr>
6406 * configure.in: We now need Autoconf 2.52e.
6407 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
6408 and `M4_SYMBOL_DELETE'.
6409 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
6410 * src/main.c (main): Adjust.
6412 2001-09-06 Gary V. Vaughan <gary@gnu.org>
6414 Fix the obstack.h problem once and for all! At configure time we
6415 can test for a system supplied obstack.h: depending on the
6416 result, we now generate system.h with an #include of the correct
6417 header. As a bonus, I've also added a --with-included-obstack,
6418 incase the user doesn't like the system obstack for some
6419 reason... and also we can test the shipped obstack on a system
6420 that has oe of its own. We also now need to be careful to add
6421 build directories to the include search path, since the generated
6422 system.h will be in the build tree.
6424 * configure.in (AC_CONFIG_FILES): Generate system.h from
6426 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
6427 include the system obstack header or the copy shipped with M4.
6428 Allow the user to override configure and force the build to use
6429 the shipped version.
6430 * m4/system-h.in: New file, template for...
6431 * m4/system.h: ...this. Now deleted.
6432 * m4/m4module.h: Include system.h before everything else.
6433 * src/freeze.c: Ditto.
6434 * m4/Makefile.am (dist-hook): Remove generated system.h.
6435 (INCLUDES): Check builddir for generated headers before checking
6437 * modules/Makefile.am (INCLUDES): Ditto.
6438 * src/Makefile.am (INCLUDES): Ditto.
6440 2001-09-05 Gary V. Vaughan <gary@gnu.org>
6442 * TODO: Remove the items that have been addressed already.
6444 2001-09-05 Akim Demaille <akim@epita.fr>
6446 * src/main.c (main): Standardize --version.
6448 2001-09-05 Akim Demaille <akim@epita.fr>
6450 * modules/format.c (format): Have a bigger `str'.
6452 2001-09-05 Akim Demaille <akim@epita.fr>
6454 Rationalize warnings, reporting the macro name as if it were a
6455 program name, and assertions.
6457 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
6459 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
6461 Use assert for internal errors.
6462 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
6464 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
6466 * tests/builtins.at (pushpop): Adjust.
6468 2001-09-05 Akim Demaille <akim@epita.fr>
6470 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
6473 2001-09-05 Akim Demaille <akim@epita.fr>
6475 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
6476 * m4/macro.c, m4/symtab.c: Adjust.
6478 2001-09-05 Akim Demaille <akim@epita.fr>
6480 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
6481 (m4_symbol_pop, m4_symbol_del): this.
6482 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
6483 (m4_symbol_popdef, m4_symbol_delete): New.
6484 (m4_lookup_symbol): Adjust.
6485 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
6487 2001-09-05 Akim Demaille <akim@epita.fr>
6489 * m4/m4module.h (m4_symbol_lookup): Rename as...
6490 (m4_symbol_lookup_t): this.
6492 2001-09-05 Akim Demaille <akim@epita.fr>
6494 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
6496 * m4/symtab.c (m4_lookup_symbol): Adjust.
6498 2001-09-03 Gary V. Vaughan <gary@gnu.org>
6500 Bootstrap will now work with Libtool 1.4.1 or higher:
6501 * bootstrap: Remove stale autom4te.cache files when
6503 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
6505 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
6506 libtool.m4 directly.
6507 Run libtoolize to refresh ltmain.sh.
6508 * config/ltmain.sh: Deleted.
6509 * acinclude.m4: Deleted.
6510 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
6512 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
6513 implementation for the cvs impaired libtool user.
6515 2001-09-03 Akim Demaille <akim@epita.fr>
6517 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
6519 Avoid using `default' in switch, as it hides useful compiler
6520 warnings when a case is forgotten.
6522 2001-09-03 Akim Demaille <akim@epita.fr>
6524 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
6525 is no such thing as `WITH_MODULES'.
6527 2001-09-03 Akim Demaille <akim@epita.fr>
6529 Improve the test suite's selfcontainedness.
6531 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
6532 (Include, Undivert): Tag the other input files.
6533 * tests/generate.awk: Catch `@comment file:'.
6534 `-I $src' is no longer needed.
6535 `next' is really like `return': the rest is skipped.
6536 Adjust to `input.m4'.
6537 (fatal): New function.
6538 * tests/foo, tests/incl.m4: Remove.
6540 2001-09-01 Gary V. Vaughan <gary@gnu.org>
6542 The shadowing mechanism and, infact, the whole symbol table
6543 implementation was creaking under the weight of the features piled
6544 on top of it. We now have a separate hash table module which will
6545 dynamically resize to keep symbol density withing good performace
6546 limits, and a new symtab module layered above it. Symbol lookups
6547 are now marginally more efficient (since the shadowed flag is no
6548 longer required) and symbol removal, such as on module unload, is
6549 considerably faster due to a reorganisation of the data structures
6552 * src/main.c (main): Don't mention `-H'.
6553 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
6556 * m4/hash.c: New generalised dynamic hash table data structure
6558 * m4/hash.h: Public interface.
6559 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
6560 (libm4_la_SOURCES): Add hash.c.
6561 * m4/symtab.c: More or less rewritten from scratch, within the
6562 bounds of the previous API.
6563 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
6564 call. Updated all callers.
6565 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
6566 declarations to reflect API changes.
6567 (M4INIT): Generate a declaration too, to avoid the warning with
6568 --enable-debug builds.
6571 * m4/utility.c (hash_table_size): Removed.
6572 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
6573 names, which are then looked up by builtin_dumpdef() as necessary.
6574 This implies a small speedup in builtin_symbols(), which discarded
6575 all of the symbol info under the old call.
6576 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
6577 shadowing is implicit in respect to the new data structures.
6578 symbol names are no longer duplicated here, they are stored in the
6579 key field of the hash table.
6580 Moved macro_args and blind_no_args...
6581 (m4_token_data): ...to here.
6582 m4/macro.c (expand_macro): Added a name argument since the symbol
6583 name is no longer copied into each struct m4_symbol. Modified all
6585 (collect_arguments): Ditto.
6586 * modules/m4.c (set_trace): Ditto.
6587 * modules/gnu.c (builtin_symbols): Updated.
6588 * src/freeze.c (produce_symbol_dump): Much improved in light of
6589 the improved symbol table layout.
6591 2001-09-01 Gary V. Vaughan <gary@gnu.org>
6593 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
6595 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
6596 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
6597 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
6598 SYMBOL_HANDLE): Ditto.
6599 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
6600 modules/gnu.c, modules/m4.c, src/freeze.c,
6601 src/main.c: Updated all references.
6603 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
6604 Automake 1.5 chokes on dynamic source file lists, Besides, it is
6605 already listed in m4_LDADD... how did that ever used to work?
6606 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
6608 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
6609 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
6611 * tests/m4: Don't call the m4 wrapper script with libtool, it
6612 works fine all by itself.
6614 2001-08-30 Gary V. Vaughan <gary@gnu.org>
6616 The experimental `changeword' feature never took off, and has
6617 no obvious advantages over `changesyntax' to compensate the
6618 enormous speed penalty it carries:
6619 * configure.in (ENABLE_CHANGEWORD): Removed.
6620 * m4/m4module.h (m4_set_word_regexp): Removed.
6621 * m4/m4private.h (m4_token_data): Removed original_text field.
6622 * m4/utility.c (m4_token_data_orig_text): Removed.
6623 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
6624 * m4/macro.c: Ditto.
6625 * src/main.c: Ditto.
6626 * modules/Makefile.am (changeword.la): Removed.
6627 * modules/changeword.c: File removed.
6628 * doc/m4.texinfo: References to changeword and --word-regexp
6630 * po/POTFILES.in: modules/changeword.c removed.
6631 * tests/atlocal.in (ENABLE_CHANGEWORD): Removed.
6632 * tests/builtins.at (changeword): Test removed.
6634 2001-08-30 Akim Demaille <akim@epita.fr>
6636 * bootstrap.sh: Create aclocal.m4 instead of modifying it.
6637 This also help having a single list of m4 files: in
6639 * config/Makefile.am (STANDARD_MACROS): Rename as...
6640 (ACLOCAL_MACROS): this.
6641 (list-standard-macros): Remove.
6644 2001-08-29 Gary V. Vaughan <gary@gnu.org>
6646 In an attempt to moderate my egomania...
6647 * tests/modules.at: Remove attributions.
6649 * tests/generate.awk: When making substitutions to "@&t@", either
6650 "&" or "\&" in the substitution string argument to gsub refer back
6651 to the matched text. "@\\&t@" seems to work though, Tests 43 and
6654 2001-08-29 Akim Demaille <akim@epita.fr>
6656 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)
6657 (include, indir, multiquotes, patsubst, pushdef/popdef, regexp)
6658 (sync-lines, trace, translit, undivert, wrap): Move to...
6659 * tests/builtins.at: this new file.
6660 * tests/others.at (Discard comments, import-environment): Move to...
6661 * tests/options.at: this new file.
6663 2001-08-29 Akim Demaille <akim@epita.fr>
6665 * tests/others.at (Freezing modules)
6666 (--module-directory: absolute path, modpath2, modpath3)
6667 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
6668 * tests/modules.at: here, new file.
6669 * tests/others.at, tests/generate.awk: Add a banner.
6670 * tests/testsuite.at: Adjust.
6671 (AT_CHECK_M4_FILTER): New, but unused.
6673 2001-08-29 Akim Demaille <akim@epita.fr>
6675 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
6677 * tests/others.at (wrap): Inline wrap.m4.
6678 (shadow): Inline shadow.m4.
6679 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
6680 * tests/m4: Simplify.
6682 2001-08-29 Akim Demaille <akim@epita.fr>
6684 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
6687 2001-08-29 Akim Demaille <akim@epita.fr>
6689 * tests/generate.awk (normalize): s/@__@/@&t@/.
6691 2001-08-28 Akim Demaille <akim@epita.fr>
6693 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.
6695 2001-08-28 Gary V. Vaughan <gary@gnu.org>
6697 * bootstrap (generate.awk): Generate test cases with new script.
6699 2001-08-27 Akim Demaille <akim@epita.fr>
6701 * tests/Makefile.am (installcheck-local): Don't use
6702 `dc_install_base' which is not visible here, but `exec_prefix'
6703 which is clearly the RT anyway.
6704 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
6705 related to testing a now installed m4.
6706 * tests/m4: Do it here.
6708 2001-08-27 Akim Demaille <akim@epita.fr>
6710 * tests/others.at (indir): Formatting change.
6712 2001-08-27 Akim Demaille <akim@epita.fr>
6714 * tests/Makefile.am (installcheck-local): New.
6715 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
6717 Prefer options over envvars.
6718 * src/main.c (main): First bug caught by the test suite (yeah!):
6719 --batch lacked a `break' which resulted in an accidental
6720 invocation of --discard-comments.
6722 2001-08-27 Akim Demaille <akim@epita.fr>
6724 * tests/others.at (capitalize, changeword, comments, ddivert)
6725 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
6726 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
6727 (sysv-args, trace, translit, undivert): Don't rely on files in
6728 examples/: AT_DATA them.
6730 2001-08-27 Akim Demaille <akim@epita.fr>
6732 Let the test suite use a wrapper around the not installed m4 to
6733 pretend it is (installed).
6735 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
6736 such a way that m4 does not process them.
6737 * configure.in: The package name seems to be `m4', not `M4'.
6739 * tests/atlocal.in (at_package, M4): Remove.
6740 * tests/testsuite.at, tests/others.at: Use m4, not $M4.
6742 2001-08-27 Akim Demaille <akim@epita.fr>
6744 * tests/Makefile.am (CLEANFILES): Remove.
6745 (DISTCLEANFILES, clean-local): New.
6746 * examples/mktests.sh: Remove.
6748 2001-08-27 Akim Demaille <akim@epita.fr>
6750 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
6751 Don't use aclocal: it's written by hand.
6752 * aclocal.m4: m4_include all the files instead of being built by
6754 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
6755 until it reads the traces by itself.
6756 * configure.in: Require Autoconf 2.42c as we are now using
6757 AC_CONFIG_TESTDIR instead of AT_CONFIG.
6758 Catch unexpanded `jm_' macros.
6759 * config/atconfig.m4: Remove.
6760 * config/error.m4: new.
6761 * config/Makefile.am: Ship the files included by aclocal.m4.
6762 * tests/Makefile.am (TESTSUITE_SOURCES): Rename as...
6763 (TESTSUITE_AT): this, to please Automake.
6764 (TESTSUITE): This target uses autotest/autotest.m4, not
6765 autotest/general.m4.
6766 * tests/testsuite.at: Prereq Autotest 2.52c.
6767 * examples/Makefile.am (pkgdata_DATA): Rename as...

6770 (dist_man_mans): this.
6772 2001-08-20 Gary V. Vaughan <gary@gnu.org>
6774 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
6775 Robert Collins, building on Cygwin no longer requires Windows
6776 import and export symbol decorations.
6777 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.
6778 * m4/error.h (M4_SCOPE) [cygwin*]: Ditto.
6779 * m4/debug.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.

6783 * m4/output.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
6784 * m4/utilty.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
6785 * m4/xmalloc.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
6786 * configure.in (LIBM4_DLL_IMPORT) [cygwin*]: Don't set this
6788 * src/Makefile.am (AM_CPPFLAGS) [cygwin*]: Don't use it either!
6789 * modules/Makefile.am (AM_CPPFLAGS) [cygwin*]: Ditto.
6791 2001-08-20 Gary V. Vaughan <gary@gnu.org>
6793 Ansify the source. Previously we had a mix, where my code was
6794 in a K&R compatible style, and the preexisting code was in ANSI
6795 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
6796 and now the code base is much cleaner.
6798 * m4/system.h: Remove M4_PARAMS macro and all users. Remove
6799 VOID macro and all users.
6800 * m4/m4module.h: Ansify function prototypes and headers.
6801 * m4/builtin.c: Ditto.
6802 * m4/evalparse.c: Ditto.
6803 * m4/input.c: Ditto.
6804 * m4/macro.c: Ditto.
6805 * m4/module.c: Ditto.
6806 * m4/output.c: Ditto.
6808 * m4/symtab.c: Ditto.
6809 * m4/utility.c: Ditto.
6810 * modules/format.c: Ditto.
6811 * modules/gnu.c: Ditto.
6812 * modules/m4.c: Ditto.
6813 * modules/mpeval.c: Ditto.
6814 * src/freeze.c: Ditto.
6816 * src/main.c: Ditto.
6818 2001-08-20 Akim Demaille <akim@epita.fr>
6820 * config/atconfig.m4: s/EOF/ATEOF/, so that configure can be
6821 generated with stock 2.52.
6823 2001-08-20 Akim Demaille <akim@epita.fr>
6825 * config/atconfig.m4: New, until part of Autoconf per se.
6826 * configure.in (AT_CONFIG): Use it.
6828 * tests/mkconfig.sh, tests/atconfig.in, tests/defs: Remove.
6829 * tests/atlocal.in: New.
6830 * tests/generate.awk: For the time being, the empty quadrigraph is
6832 * tests/others.at (changeword, gmp): Check the configuration
6833 variable against `yes'.
6834 * tests/testsuite.at (dnl): Allow it, as it's used all over the
6837 2001-08-20 Akim Demaille <akim@epita.fr>
6839 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
6840 * modules/m4.c (undivert): Disable the possibility of undiverting
6841 several files at once: it is not documented, it is inconsistent
6842 with the other macros, it can be straightforwardly mocked by
6843 several invocations, and most importantly, it prevents the
6844 possibility of other kinds of extension.
6845 Use `m4_numeric_arg'.
6847 2001-08-20 Akim Demaille <akim@epita.fr>
6849 * examples/include.m4: Typo.
6850 * tests/generate.awk: Really add it.
6851 * tests/Makefile.am: Adjust.
6852 * tests/others.at (Discard comments): It sure fails without `-c'.
6853 (include, undivert): Add -I examples/.
6855 2001-08-20 Akim Demaille <akim@epita.fr>
6857 Use sprintf, not ecft and friends since it is standard, portable,
6858 simplifies the code, and since the latter is even deprecated
6859 according to the GNU libc documentation.
6861 * modules/format.c: Drop evct support.
6863 2001-08-19 Gary V. Vaughan <gary@gnu.org>
6865 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Cleaned up. Don't test
6867 * configure.in: ...do it here instead.
6869 * c-boxes.el: Deleted.
6870 * m4/builtin.c: Reformat box comments to be closer to GNU
6872 * m4/debug.c: Ditto.

7007 Drop Autoconf 2.13 compatibility.
7009 * configure.in (changeword): No need to undefine it, as anyway if
7010 it's defined, M4sugar moved it as m4_changeword.

7012 (m4_pattern_allow): As it exists in 2.50, just use it.

7067 (M4INIT_HANDLER): Clean way to declare init functions in modules.
7068 (M4FINISH_HANDLER): And similarly for finish functions.
7069 * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER
7070 -- Add indirection to the CONC macro so that arguments are
7072 * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
7073 * modules/shadow.c (m4_init_module): Ditto.

7076 * modules/perl.c (m4_init_module): Ditto. And Ditto.
7077 (m4_finish_module): Replaced with M4FINISH_HANDLER.

7081 (m4_module_data): ...structure without all the wrapper fields.
7082 Instances of this new structure are stored associated lt_dlhandles
7083 with lt_dlcaller_data_set().

7085 instead of the old module argument.
7086 (m4_builtin_table_install): Ditto.
7087 * modules/load.c (m4_resident_module): Removed. This is no
7088 longer implemented as a magic symbol...
7089 * modules/m4.c (m4_resident_module): Ditto.
7090 * modules/load.c (M4INIT_HANDLER): ...the module init function now

7106 various tokens that are passed between functions.
7107 (struct m4_symbol): Removed the module field. The
7108 module association does not belong with the symbol...
7109 * m4/input.c (struct m4_builtin): ...it belongs with the builtin
7110 that the module implementation code is from. Added a handle
7112 (m4_push_macro): Add a `handle' argument. Changed all callers.
7113 (init_macro_token): Set the `handle' field for the
7115 * m4/macro.c (expand_argument): Copy the new handle field during
7117 * modules/m4.c (macro_install): Use the new handle field to
7118 optimise the search for the correct builtin structure, and pass
7119 the handle details to m4_builtin_define.
7121 2001-08-15 Akim Demaille <akim@epita.fr>
7123 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Be sure `m4/' exists
7124 when creating `m4/obstack.h'.
7125 * tests/Makefile.am (TESTS_ENVIRONMENT): Pass top_srcdir and
7127 * tests/defs: Make them absolute.
7128 (CDPATH) Neutralize.
7129 * tests/gethem: Use them.
7131 2001-08-14 Gary V. Vaughan <gary@gnu.org>
7133 * config/ltmain.sh: Doh! Import again for a quoting fix that
7134 prevented any regression test from passing.
7136 * m4/m4module.h (obstack.h): Choose between installed version
7137 and shipped version based on configure tests.
7138 * src/freeze.c (obstack.h): Ditto.
7140 * acconfig.h: Removed. No longer required.
7142 * bootstrap: Rewritten to play nicely with Autoconf 2.5x.
7143 * configure.in (MY_NAME, MY_VERSION): Define these once, and feed
7144 them to AC_INIT and AM_INIT_AUTOMAKE.
7145 * Makefile.am (AUTOMAKE_OPTIONS): Remove `gnits' which would
7146 disallow MY_NAME and MY_VERSION arguments to AM_INIT_AUTOMAKE.
7147 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Don't choke on
7148 shell variable m4_cv_func_obstack_h.
7149 * tests/defs (M4): Be more careful about relative path to libtool
7150 script and m4 binary by using $srcdir.
7152 * src/main.c (main): Use lt_dlinsertsearchdir to prepend -M
7153 optargs to the existing libltdl search path.
7154 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.
7155 * m4/ltdl.c: Updated.

7159 2001-08-11 Gary V. Vaughan <gary@gnu.org>
7161 * src/main.c (main): Add `-b' (for `batch') mode switch to force
7162 interactive mode off.
7164 2001-08-10 Akim Demaille <akim@epita.fr>
7166 * configure.in: Require Autoconf 2.52.
7167 (AC_ARG_PROGRAM): Remove, handled by Automake.
7168 (m4_getopt): Rename as...
7169 (m4_getopt_h): this.
7170 Allow the tokens `m4_cv_*', `m4_top_srcdir', and `m4_getopt_h'.
7171 Undefine `changeword' only if defined.
7172 * config/gnu-obstack.m4: Require Autoconf 2.52.
7173 (M4_AC_FUNC_OBSTACK): Rename `m4_obstack' and `m4_obstack_h'.

7186 2001-08-07 Akim Demaille <akim@epita.fr>
7188 Improve `make distcheck'.
7190 * configure.in: Be sure to be able to run `mkconfig.sh' when src

7193 * doc/m4.texinfo (Include): Add missing blank.

7227 * TODO: Removed m4exit bug.
7228 * modules/load.c (m4_resident_module): Make this module resident.
7229 * module/m4.c (m4_resident_module): Ditto.
7230 * m4/modules.c (m4_module_load): Use new ltdl resident modules
7231 feature to mark modules as resident if they export
7232 `m4_resident_module' as TRUE.
7233 (m4_module_unload): Do not remove resident modules, and take care
7234 with symbol insertion and deletion with resident modules.
7235 * m4/ltdl.c, m4/ltdl.h: Update to latest unreleased versions to
7236 use resident modules feature.
7238 2000-11-30 Gary V. Vaughan <gary@gnu.org>

7252 * src/main.c (usage): Added missing description of `-c' option.
7254 2000-11-29 Gary V. Vaughan <gary@gnu.org>
7256 Consolidate the myriad of dispersed test scripts into the
7257 tests subdirectory. I think I now have all the file where I

7299 Move the implementation of GMP support for the mpeval() builtin
7300 into a loadable module that depends on libgmp. mpeval() and
7301 eval() share a common parser, now in m4/evalparser.c; the code
7302 in m4/numb.c and m4/numb.h is now physically split between
7303 m4/eval.c (the eval() backend) and modules/mpeval.c (the
7304 mpeval() backend), rather than being differentiated by cpp
7305 macros and multiple inclusion. The mpeval module is always
7306 built but will generate an diagnostic if it is used from an
7307 installation that didn't link in the gmp library.
7308 * modules/Makefile.am: build and install the new mpeval module.
7309 * modules/mpeval.c: Now contains the former parts of m4/numb.c
7310 and m4/numb.h that are required for gmp support in mpeval().
7311 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
7312 * m4/evalmp.c: Removed.
7313 * m4/m4module.h: Removed conditional prototype for
7315 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
7316 and m4/numb.h that do not rely on gmp.
7317 * m4/evalparse.c: New file, contains the shared parts of the
7318 eval() and evalmp() parser implementations, and is no longer
7319 unencumbered by cpp magic to uncover the right parts.
7320 * m4/numb.h: Removed. It's former contents are split between
7321 m4/eval.c and modules/mpeval.c.
7324 * tests/other-tests/changeword.test: New test. Rudimentary
7325 testing of changeword builtin runs only if --wnable-changeword
7326 was used at configure time.
7327 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
7328 alternation correctly. Split into two expressions to compensate.
7329 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
7330 * modules/Makefile.am: Build changeword module.
7331 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
7332 only when --enable-changeword was passed to configure.
7333 (builtin_changeword): If --enable-changeword was not used, then
7334 report that changeword() builtin has no support in m4 binary.
7336 2000-11-28 Gary V. Vaughan <gary@gnu.org>
7338 * src/main.c (main): Fixed a particularly nasty bug is
7339 user_search_path setting -- the -M flag processing must be
7340 extremely careful with search path ordering, or else the default
7341 installed module directory (possibly containing modules from a
7342 previous release) is placed earlier in the search path than any -M
7343 arguments (which are relied upon to load uninstalled modules with
7344 most of the tests in the regresion suite).
7346 * modules/load.c (builtin_load): Nasty hack to prevent adding
7347 symbols to symtab again if a module is loaded more than once.
7348 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
7350 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
7351 possible NULL pointer dereference.
7353 * m4/module.c (m4_module_find_by_modname): Renamed from
7354 m4_module_modname_find. Fixed all references.
7355 (m4_module_find_by_builtin): New function.
7357 * modules/modfreeze.test: load the `load' module with each
7359 * src/freeze.c (produce_frozen_state): Simplified in light of
7360 module field in m4_symbol. Allow a third argument for text macros
7361 to name the originating module.
7362 (reload_frozen_state): ditto.
7363 * m4/m4module.h: Fixup prototypes.
7364 * m4/builtin.h (m4_builtin_define): Add a module argument so
7365 that symbols can be registered against the defining module.
7366 (m4_macro_define): ditto.
7367 * m4/m4private.h (m4_symbol): Make the module field const to save
7368 on casting in the rest of the code.
7369 (SYMBOL_MODULE): New macro.
7371 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
7372 symbol reference maintenance bugs when removing a symbol from the

7377 2000-11-27 Gary V. Vaughan <gary@gnu.org>
7379 * configure.in (m4_cv_func_obstack): A better check for whether
7380 libc has an obstack implementation.
7381 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
7383 * configure.in (--with-modules): Changed semantics. This
7384 option is now used to list modules to be preopened.
7385 * src/m4.h: #include "ltdl.h" unconditionally.
7386 * src/main.c: Removed all dependencies on WITH_MODULES.
7387 * src/freeze.c: ditto.
7388 * modules/Makefile.am: ditto.
7389 * m4/m4.c (builtin_m4exit): ditto.
7390 * modules/modpath1.test: ditto.
7391 * modules/modpath2.test: ditto.

7399 comes up on demand in LTLIBOBJS now.
7400 * configure.in (getopt_long): Creating and relying on a link for
7401 getopt.h on hosts with no getopt_long() of thier own works
7402 correctly now. This is necessary so that callers of getopt_long()
7403 can simply `#include <getopt.h>': the naive way of doing this
7404 would end up using our own getopt.h and the installed
7405 getopt_long(), which is asking for trouble!
7406 (obstack_init): A similar argument applies to obstack.h and
7409 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
7410 On Solaris-2.5 (at least) the native dlopen implementation
7411 gets confused about m4.o when looking for module "m4". This
7412 version always looks for .la an .$lib_ext suffixed names first
7413 to work around the problem. Sigh.
7415 * po/POTFILES.in: Take account of these file movements.
7416 * src/Makefile.am (m4_SOURCES): removed eval.c.
7417 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
7418 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
7419 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
7420 * modules/m4.c (builtin_eval): Use m4_evaluate().
7421 * m4/eval.c: Moved here from src/eval.c to facilitate
7422 implementation of eval() builtin as part of the `m4' loadable
7424 (m4_evaluate): renamed from evaluate for namespace cleanliness.
7425 * m4/numb.c: Moved here from src/numb.c, since it is #included
7426 into eval.c at compile time.
7427 * m4/m4module.h (m4_evaluate): Added prototype.
7428 * src/m4.h (evaluate): Removed prototype.
7430 2000-11-25 Gary V. Vaughan <gary@gnu.org>
7432 * modules/perl.c (builtin_perleval): Use PL_na for
7433 compatibility with perl-5.6.
7435 * src/main.c (main): It is now safe to
7436 ``m4_module_install("m4")'', without tripping over the m4
7438 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
7439 versions having fixed the insidious module search order bug.
7441 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
7442 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
7444 * configure.in: Figure out whether to use the installed
7445 getopt.h or the supplied one.
7446 * src/Makefile.am: ditto.
7448 * po/POTFILES.in: List files in their new positions.
7450 * config/ltmain.sh: This needs to be checked in to match the
7451 libtool macros copied to acinclude.m4 (until a released
7452 libtool copes with m4's needs).
7453 * bootstrap: Run gettextize.
7455 2000-11-24 Gary V. Vaughan <gary@gnu.org>
7457 * AUTHORS: Added my details.
7460 * bootstrap: temporary update until released libtool catches up.

7497 definitions for all the gnu extension builtins.
7498 * modules/format.c: Moved here from src/format.c. Now included
7501 * src/main.c (main): Load the traditional module if m4 was
7502 started in `no_gnu_extensions' mode.

7522 * m4/symtab.c: ditto.
7523 * m4/debug.c: ditto.

7527 * m4/ltdl.h, m4/ltdl.c: ditto.
7528 * m4/utility.c: Odd functions moved here from files in the src
7529 directory to facilitate builtin migration.
7531 2000-08-12 Gary V. Vaughan <gary@gnu.org>
7533 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
7534 error message, to make translators' jobs a little easier.
7535 (builtin_builtin): ditto.
7536 (builtin_traceon): ditto.
7537 (builtin_traceoff): ditto.
7538 Reported by Akim Demaille <akim@epita.fr>

7541 pkgincludedir instead.

7564 makeinfo calculates them for us, and to make any future
7565 reorganisation easier.
7566 (Frozen files): Document format version 2.
7567 `V' now takes argument `2'.

7712 * src/builtin.c: Much improved macro definition style.
7713 * src/m4private.h: Internal structures for m4_builtin and

7768 * modules/modpath4.test: ditto.

7782 increment serial number.
7784 * Makefile.am (SUBDIRS): Moved @MODULES_DIR@ to compile before
7785 src dir and immediately after libm4 is built for confidence that
7786 it doesn't rely on the src directory.
7787 (SUBDIRS): Moved doc dir to the end since helptoman.pl and
7788 makeinfo stop the build on cygwin (because they don't work).
7790 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
7792 * m4/m4private.h: ...is not a public header, so moved to src.

7836 From Akim Demaille <akim@epita.fr>
7838 2000-01-17 Gary V. Vaughan <gary@gnu.org>
7840 * src/ltdl.c: Use access() to abort doomed module load attempts
7841 if module file does not exist.
7843 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
7844 getopt1.o will already be used if appropriate, so I moved getopt.c
7845 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
7847 * modules/modpath1.test: Use correct filename in header line.
7848 * modules/modpath2.test: ditto.
7849 * modules/modpath3.test: ditto.
7850 * modules/modpath4.test: ditto.
7852 Without these changes lt_dlopen("test") attempts to
7853 LoadLibrary("/bin/test") on Windows, which although harmless
7854 generates a spurious error message which spoils most of the tests:
7855 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
7856 (TESTS): s/test.test /modtest.test /
7857 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /

7875 * modules/Makefile.am (TESTS): New tests for the module system.
7877 * modules/*.test: New files.
7879 * src/m4.c (main): Added call to module_init().
7880 Treats -M and -m as the arguments -D -U and -t, ie deferred.
7882 * src/m4.h: Added declaration of module_init().
7884 * src/module.c (module_init): No longer static
7886 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
7887 Added to shut up automake about non standard libtool library
7890 * src/module.c: Disabled DEBUG by default.
7892 * modules/README: Changed example from unload.m4 to shadow.m4
7894 * modules/shadow.m4: Renamed from unload.m4
7896 * modules/Makefile.am (EXTRA_DIST): Removed unload.m4.
7898 * src/m4.c (main): Functionality for -m and -M were reversed.
7901 2000-01-12 Gary V. Vaughan <gary@gnu.org>
7903 * doc/help2man.pl: updated to version 1.020.
7905 * lib/COPYING.LIB: updated to version 2.1.
7907 * lib/m4module.h: restructure the M4_SCOPE code to work when
7908 creating a dll which links with libm4.la and both DLL_EXPORT
7909 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
7912 2000-01-11 Gary V. Vaughan <gary@gnu.org>
7914 Merged the following changes from my tree:
7916 1999-06-15 Gary V. Vaughan <gary@gnu.org>
7918 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
7919 ported to compile shared libs.
7921 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
7922 use `__declspec(dllimport)' when linking libm4.la on win32.
7923 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
7925 * configure.in (M4OBJS): Discover whether we need the shipped
7926 implementation of getopt_long.
7927 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
7928 main binary here, as opposed to the module library in lib/libm4.la.
7930 1999-06-14 Gary V. Vaughan <gary@gnu.org>
7932 * modules/README: Updated to describe the improved libltdl based
7934 * README (cygwin): Added some compilation notes for building m4
7935 correctly under cygwin.
7936 * TODO: Cleaned out the entries for the module system since they
7937 are now implemented.
7939 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
7940 all instances of __P with M4_PARAMS.
7942 * lib/getdate.h: removed unreferenced file.
7944 * lib/m4private.h: New file to define the private interface to the
7945 token_data struct, which must be shared between m4module.c, and
7946 builtin.c but not exported to modules built from the installed
7947 m4module.h since it's size changes depending on compile time
7950 * src/m4.h: Lots of stuff moved to lib/m4module.h.
7952 * lib/m4module.h: New file to define the interface available when
7953 compiling m4 modules.
7954 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
7955 necessary for module compilation into this new file.
7957 * lib/Makefile.am (include_HEADERS): install headers (renamed to
7958 avoid nameclash with other system headers) necessary for compiling
7960 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
7961 so that modules can include the (renamed) installed headers and
7962 be guaranteed a matching implementation.
7963 * lib/m4error.h: renamed from error.h.
7964 * lib/m4obstack.h: renamed from obstack.h.
7965 * lib/m4regex.h: renamed from regex.h.
7966 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
7967 implementation, simply include the shipped version
7968 unconditionally, otherwise it is hard for a module to know
7969 whether the m4obstack.h header it is using matches the
7970 implementation it ends up linking against.
7971 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
7974 1999-05-18 Gary V. Vaughan <gary@gnu.org>
7976 * examples/misc.test: Don't run this test on machines which don't
7977 have a root user in /etc/passwd (e.g. cygwin).
7979 * tests/get-them (/^@example$/): Error messages might have a
7980 ``.exe'' suffix to the program name, or else use the libtool
7981 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
7982 of these cases are now catered for when comparing error messages
7984 * tests/other-tests/*.test: ditto.
7985 * examples/*.test: ditto.
7987 * tests/defs (M4): use libtool execute mode.
7988 * examples/defs (M4): ditto.
7990 * tests/get-them (END): explicitly close any open file.
7991 (printthem): In a regular expression, '{' is the start of a repeat
7992 count! Use `[{]' for a literal open brace.
7993 (/^@node /): Don't use substr on a string shorter than the trim
7996 1999-05-17 Gary V. Vaughan <gary@gnu.org>
7998 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
8000 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
8002 2000-01-10 Andreas Schwab <schwab@suse.de>

8006 * configure.in: Find tests/mkconfig.sh in $srcdir.
8008 * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in

8014 2000-01-10 René Seindal <rene@seindal.dk>
8018 * TODO, NEWS: Cleaned up and updated.
8020 * src/m4.c (main): New variable exit_status for exit status in
8021 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
8022 file cannot be read instead of EXIT_SUCCESS.
8024 * src/builtin.c (m4_indir): Changed error message to help
8025 translators (from Akim Demaille <demaille@inf.enst.fr>).
8027 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
8030 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
8033 * src/input.c (match_input): Reordering of code, to avoid multiple
8034 calls to push_string_init() from obstack_grow(), which can happen
8035 with some compilers (found and fixed by James Bonfield
8036 <jkb@mrc-lmb.cam.ac.uk>).
8038 * src/stackovf.c: Added prototypes for ultrix.
8039 (setup_stackovf_trap): Added __P to cast.
8040 (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>)
8042 2000-01-09 René Seindal <rene@seindal.dk>
8044 * doc/m4.texinfo (Changequote): Added comment about changing
8045 quotes when the old quote is a part of the new.
8047 * src/builtin.c (expand_ranges): Added break after trailing dash.
8048 This caused misbehavious on some systems (found and fixed by Akim
8049 Demaille <demaille@inf.enst.fr>).
8051 * AUTHORS: Thomas Tanner included
8053 * acconfig.h: Added entry for ss_sp (see below).
8055 * configure.in (use_stackovf): Added check for stack_t with member
8056 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert
8057 <eggert@twinsun.com>).
8059 * doc/m4.texinfo (Frozen files): Added a simpler example for
8060 generating frozen files from several input files.
8062 1999-11-14 Paul Eggert <eggert@twinsun.com>
8064 * po/POTFILES.in: Add lib/getopt.c, lib/obstack.c,
8065 lib/regex.c, lib/xmalloc.c.
8067 1999-11-10 René Seindal <rene@seindal.dk>
8069 * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal.
8071 * src/module.c: reindented.
8072 (module_load): return if this is a repeated load of same module.
8073 (module_init): slight change of logic to avoid repeated
8074 initialisation debug messages.
8076 * Makefile.am (DIST_SUBDIRS): Added to ensure modules/ is included
8077 in the distribution.
8079 * modules/Makefile.am (test_la_LDFLAGS): set to -module to silence
8080 automake warnings about missing lib prefix.
8081 (time_la_LDFLAGS): ditto
8082 (stdlib_la_LDFLAGS): ditto
8084 1999-11-10 Paul Eggert <eggert@twinsun.com>
8086 * src/m4.h: Include error.h, since our macros use error.
8087 * src/m4.c: Don't need to include error.h.
8089 1999-11-09 Paul Eggert <eggert@twinsun.com>
8091 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
8092 and zero, as Solaris 7 cc does.
8093 (bcopy): Remove macro; no longer needed with new obstack.h.
8095 * src/output.c (freeze_diversions): Don't assume that a
8096 diversion size can fit in `int'. Check for diversion file
8097 size too large to be printed with `unsigned long'.
8099 * src/Makefile.am (CFLAGS): Omit -Wall.
8101 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.
8103 * src/debug.c (trace_format):

8126 1999-03-30 Gary V. Vaughan <gary@gnu.org>
8128 * src/builtin.c: moved module loading functions into...
8129 * src/module.c: entirely new implementation using libltdl.
8130 * po/POTFILES.in: added src/module.c.
8131 * modules/Makefile.am (LTLIBRARIES): Removed lib prefix as these
8132 are modules, not linktime libraries.
8133 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
8134 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
8135 avoidance on exported symbols.
8136 * modules/test.c (m4_macro_table, m4_init_module,
8137 m4_finish_module): ditto.
8138 * modules/time.c (m4_macro_table): ditto.
8140 * modules/time2.m4: new file which requires command line loading
8142 * src/m4.c (--load-module): dynamically load named runtime module
8143 into running executable before reading the source.
8144 (--module-directory): prepend a directory to the module search
8146 (module_init()): Do this the first time we load a module instead;
8147 if the module subsystem is broken normal m4 scripts can still run.
8148 * src/m4.h (install_builtin_table): is now exported.
8150 1999-03-26 Gary V. Vaughan <gary@gnu.org>
8152 * src/module.c: removed. No longer required.
8153 * po/POTFILES.in: removed src/module.c.

8162 * modules/Makefile.am (MAINTAINERCLEANFILES): ditto.
8163 * src/Makefile.am (MAINTAINERCLEANFILES): ditto.
8164 * tests/Makefile.am (MAINTAINERCLEANFILES): ditto.
8166 * acinclude.m4: removed. `aclocal -I acm4' handles this much
8168 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
8169 * acm4/gettext.m4: removed. It causes a multiple definition vs.
8170 the installed gettext.m4 file when running aclocal.
8172 1999-03-25 Gary V. Vaughan <gary@gnu.org>
8174 * configure.in (AM_INIT_AUTOMAKE): bumped version number to
8175 distinguish this from the last prerelease.
8176 (AC_LIBLTDL_CONVENIENCE): build libltdl as a convenience library
8177 in its own subdirectory.
8179 * modules/Makefile.am (*_SOURCES): renamed to use libtool's "no
8180 lib prefix on a module" feature.
8181 (LDFLAGS): Added `-module -avoid-version' flags to build
8182 versionless module libraries.
8183 * src/builtin.c (m4_load_module): use libltdl.
8184 (module_unload_all): use libltdl.
8185 * src/m4.c (module_init): initialise module loading on demand for
8186 better diagnostics, and so that m4 will still work even if
8187 the module code is broken.
8188 * src/m4.h (module_init): removed. No longer relevant.
8189 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on
8190 exported symbols for compatibility with dlpreopening.
8191 * modules/test.c (m4_macro_table, m4_init_module,
8192 m4_finish_module): ditto.
8193 * modules/time.c (m4_macro_table): ditto.
8195 * bootstrap: New file. Runs all the autoutils in the right order
8196 after a fresh checkout, or a make maintainer-clean.
8198 1999-02-18 Akim Demaille <demaille@inf.enst.fr>
8200 * src/builtin.c (dump_symbols): New function, factoring common
8201 content of m4_dumpdef and m4_symbols.
8202 (m4_dumpdef): Use it.
8203 (m4_symbols): New function, implementing `symbols'. Use it.
8204 * doc/m4.texinfo: Fixed missing commas after @xref, so that the
8205 file compile with modern makeinfo.

8211 * src/builtin.c (predefined_tab): New predefined macros
8212 __m4_changeword__, __m4_gmp__ and __m4_modules__ for testing for
8213 configure time options.
8215 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
8217 * src/module.c (module_try_load): Don't try to be clever and
8218 overwrite argument string. Instead allocate all constructed
8219 strings locally, since they can have arbitrary lengths. Make
8220 arguments pointers to const.
8221 (module_search): Simplify due to above change.
8223 1998-11-29 René Seindal <rene@seindal.dk>
8227 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): New tests.
8229 * tests/other-tests/import-environment.{m4,test}: New test.
8231 * tests/other-tests/discard-comments.{m4,test}: New test.
8233 * doc/m4.texinfo (Invoking m4): Updated for --discard-comments.
8235 * src/m4.c (main): New option -c --discard-comments.
8236 New global variable discard_comments.
8238 * src/m4.h (token_type): New TOKEN_NONE for tokens to be

8243 TOKEN_NONE. Comments are now given this type when comments should
8246 * doc/m4.texinfo (Invoking m4): Updated for --import-environment
8249 1998-11-28 René Seindal <rene@seindal.dk>
8251 * src/m4.c (main): New option --import-environment (no single
8254 * When configured with --with-gmp both the normal (fast) eval()
8255 and the gmp aware mpeval() are defined. To restore previous
8256 bahaviour use "define(`eval', defn(`mpeval'))".
8258 * tests/other-tests/gmp.m4: Changed to use mpeval().
8260 * src/evalmp.c: New file for compiling eval.c as gmp aware.
8261 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
8263 * src/eval.c: Now includes "numb.c" directly. Everything in this
8264 file must by static, except evaluate(), which is changed to
8265 mp_evaluate() if USE_GMP in force.
8267 * src/numb.c: Changed to be included by eval.c instead of being
8268 compiled separately. Everything is declared static.
8270 * src/numb.h: Removed declarations of functions, as numb.c is now
8273 * src/builtin.c: Declaration of m4_mpeval() added.
8274 Inserted `mpeval' in builtin table.
8275 (do_eval): New function with common code for m4_eval and m4_mpeval.
8276 (m4_mpeval): New function for gmp version of eval.
8278 * src/m4.h: Declaration of mp_evaluate().

8281 (EXTRA_m4_SOURCES): Now has numb.c and numb.h
8283 * src/m4.c (main): m4 --version also shows which options were used
8284 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
8286 1998-11-27 René Seindal <rene@seindal.dk>
8288 * Error messages now always print program name before input file
8289 name as specified by GNU coding standards. Reported by Akim
8290 Demaille <demaille@inf.enst.fr>.
8292 * doc/m4.texinfo (Include): Change due to changed error message
8296 * tests/get-them: Minor change to sed script due to changed error
8299 * src/m4.c (print_program_name): New func used to print program
8300 name, input file and line number in error (). Used as an
8301 error_print_progname handler.
8302 (reference_error): Removed.
8303 (main): Assigns error_print_progname.
8305 * src/m4.h (M4ERROR): Removed reference_error ().
8307 1998-11-25 René Seindal <rene@seindal.dk>
8309 * Updated to libtool 1.2b.
8311 * src/builtin.c (install_builtin_table): Added braces to avoid
8312 warning of ambiguous 'else'.
8314 * src/module.c: Inserted search path code from path.c modified to
8316 (module_init): Configured default path used only if M4MODPATH is
8318 (module_try_load): Now reads libMODULE.la as generated by libtool
8319 for actual module name.
8320 (module_load): Gives better error messages on failure.
8322 * src/m4.h: Added declarations of structures and functions for
8323 generic search path handling.
8325 * src/path.c: Removed all module specific code and introduced new
8326 functions of more generic search path handling.
8328 1998-11-24 René Seindal <rene@seindal.dk>
8330 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
8331 included gettext, as <libintl.h> might not be found
8332 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
8334 1998-11-22 René Seindal <rene@seindal.dk>
8336 * src/output.c (insert_diversion): Fixed bug that might cause m4
8337 to read from standard output! Triggered by input
8338 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
8339 so now 'undivert(0)' does nothing.
8341 1998-11-18 René Seindal <rene@seindal.dk>
8345 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
8346 could be changed when compiling a illegal regexp, causing later
8347 use of the regexp to dump core.
8349 * src/module.c (module_load): Changed error message to conform to
8352 * src/m4.c (usage): Added message about reporting bugs.
8354 * doc/m4.texinfo (Changeword): Corrected a wrong example.
8355 (Changeword): Added note about the type of regexps used.
8357 * ltconfig, ltmain.sh: New files from Libtool 1.2.
8359 * configure.in: Added calls to AM_ENABLE_SHARED, AM_DISABLE_STATIC
8360 and AM_PROG_LIBTOOL.
8362 * acm4/modules.m4 (AM_WITH_MODULES): Redone completely to work
8365 * modules/Makefile.am: Changed completely to compile modules using
8366 libtool. The modules are compiled as shared libraries, and are
8367 renamed when installed.
8369 * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
8370 USE_SHL_LOAD to HAVE_SHL_LOAD
8372 * src/builtin.c (shipout_string): Now tests for a NULL string.
8374 * src/module.c: New level of indirection around non-portable
8375 functions to load shared objects. Intended to encapsulate the non
8376 portable parts better and to reduce the number of #ifdefs in the
8379 * Makefile.am (DIST_SUBDIRS): Instead of EXTRA_DIST for added
8380 directory modules/ to the distribution.
8382 1998-11-15 René Seindal <rene@seindal.dk>

8387 functions: getcwd, getlogin, getpid, getppid, getuid, getpwnam,
8388 getpwuid, hostname, rand, srand, getenv, setenv, unsetenv, uname.
8390 * src/builtin.c (shipout_string): New convenience function for
8391 builtins and modules.
8393 * src/module.c (module_load): Tentative support for
8394 shl_load/shl_findsym, but I cannot test it. Copied from MetaHTML.
8396 * Makefile.am (SUBDIRS): Directory modules added if configured.
8398 * modules/Makefile.am: Now correctly compiles and installs
8399 modules in pkglibexecdir.
8401 * src/m4.h: WITH_MODULES defined iff HAVE_DLOPEN or USE_SHL_LOAD.
8402 These two are now initialised by autoconf macros.
8404 * src/path.c (module_env_init): MODULE_PATH is always on the
8407 * src/Makefile.am: Now generated pathconf.h which defined the
8408 default MODULE_PATH.
8410 * configure.in (pkglibexecdir): Added defintion of pkglibexecdir,
8411 where modules are installed.
8413 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
8414 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
8415 build and install automatically, and it is prepared for other
8416 interfacec than dlopen().
8418 * src/builtin.c (predefined_tab): Added __m4_version__ for the
8419 current version of GNU m4. It is a GNU extension.
8421 1998-11-14 René Seindal <rene@seindal.dk>
8423 * tests/Makefile.am (GENERATED_TESTS): Added new
8424 generated-tests/changesy.8.test
8426 * doc/m4.texinfo (Changesyntax): Documentation for escape

8430 symbol table lookup.
8432 * src/builtin.c (m4_changesyntax): Added `@' flag to define escape
8435 * src/input.c: New static variable use_macro_escape, which is TRUE
8436 iff some character has code SYNTAX_ESCAPE
8437 (input_init): Added initialisation of use_macro_escape.

8499 1998-10-07 René Seindal <rene@seindal.dk>
8503 * tests/Makefile.am (GENERATED_TESTS): Changed .m4 extension to

8506 * tests/get-them (FILE): Changed .m4 extension to .test.
8508 * src/m4.h (token_type): New token type TOKEN_SPACE introduced.
8509 Otherwise quoted strings with leading whitespace first in a macro
8510 argument would be eliminated.
8512 * src/macro.c (expand_token): Handles new token type TOKEN_SPACE.
8513 (expand_argument): Do.
8515 * src/input.c (next_token): SPACE and NUM/OTHER characters are only

8521 builtin_table on the stack without installing its contents.
8522 (find_builtin_by_name): Added call to push_builtin_table() if

8549 * src/builtin.h: New file, declares some functions from builtin.c
8550 that are of use for other modules (shipout_int, numeric_arg,
8551 skip_space, bad_argc), and the macros ARG() and DECLARE().
8553 * src/builtin.c (install_builtin_table): New function. Each
8554 module brings in a builtin_table, which is pushed on a stack.
8555 (struct builtin_table): New struct for list of builtin_tables.
8556 (m4_loadmodule): New function to implement builtin "loadmodule".
8557 (shipout_int): No longer static, to be used by modules.

8578 * configure.in: Added modules/Makefile to AC_OUTPUT.
8580 * configure.in: Added code to implement --with-modules. Tests for
8583 * acconfig.h: Added WITH_MODULES
8585 1998-10-02 René Seindal <rene@seindal.dk>
8587 * examples/Makefile.am (pkgdata_DATA): Removed special target for
8588 check and variables TESTS. These tests are now run from the
8591 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
8592 directory. The files stay there but the tests are run from the
8595 * tests/Makefile.am (EXTRA_DIST): Added run-test.
8597 * tests/run-test: New file. Run a test manually
8599 * tests/Makefile.am, tests/get_them: Moved automatically generated
8600 tests (from the manual) to sub directory tests/gentest/. The
8601 tests/ directory had gotten a bit messy.
8603 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
8605 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\
8606 wrap}.test: Added a few testcases.
8608 1998-08-21 Erick Branderhorst <Erick.Branderhorst@asml.nl>

8614 * configure.in (jm_WITH_REGEX, jm_PREREQ_ERROR):
8615 acm4/{error,regex}.m4 (from fileutils-3.16u.tar.gz).
8617 * acm4/Makefile.am: created providing rules to create
8618 $(top_srcdir)/acinclude.m4 to be used by aclocal.
8620 * tests/defs (LANGUAGE, LC_ALL, LANG): force them to be
8621 `C'. Reported by Ulrich Drepper.
8623 * Makefile.am (SUBDIRS): Removed checks directory
8624 * configure.in (AC_OUTPUT): Removed checks/Makefile
8626 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
8627 the space when m4.texinfo is edited and whitespace.el is active.
8628 (Defn,example): idem.
8630 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
8632 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
8633 ../COPYING. ../Makefile is a file which is certainly present when
8634 test is executed in testSubDir. One can't be sure that the COPYING
8635 file is in .. or ../.. in all situations, the ../Makefile is
8638 * doc/m4.texinfo (Include): adjusted expected test output
8639 according to new tests, i.e. the input will always come from the
8640 file `in' created by the test.
8642 * tests/Makefile.am: Added three lines at the top to get
8643 esyscmd.1.test working.
8645 * tests/get-them: modified to generate clearer tests who will need
8646 less maintenance when new test examples are created in
8647 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
8648 need the generic file `defs') shell scripts creating `in', `ok',
8649 `out' and when apropriate `okerr' and `err' in the directory
8650 `testSubDir' when executed. The compare of `ok' and `out'
8651 (and of `okerr' and `err') will be the exit status of the test.
8652 `out' must match `ok' (and `okerr' must match `err') for the test
8655 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
8656 the tests generated by tests/get-them getting it input normally
8657 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
8658 (dot) before the numeric part) is reserved for all other (hand
8659 written) tests. The `+' means one or more times.
8661 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
8663 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
8664 supported short man page to refer to info documentation

8691 "changesyntax" to modify the syntax table.
8693 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax
8694 table. All categories are assigned a syntax code and tokens are
8695 read according to this table.
8697 1998-08-09 René Seindal <rene@seindal.dk>
8699 * src/numb.{c,h}: New files, implements multiple precision eval
8700 using GNU gmp. Originally submitted by John Gerard Makecki
8701 (johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.
8703 * doc/m4.texinfo (Eval): Added documentation for multiple
8704 precision arithmetic library support.
8706 * src/m4.{c,h}, src/eval.c, src/builtin.c, configure.in: Changes
8707 to accommodate multiple precision eval.
8709 1998-08-07 René Seindal <rene@seindal.dk>

8727 * src/m4.h: Added ifdef ENABLE_NLS around include of <libintl.h>
8728 and _ macro. M4 now builds with --disable-nls.
8730 * src/m4.c (main): reintroduced textdomain(PACKAGE) to get gettext
8731 to look for right message catalogs. Call indef'ed by ENABLE_NLS.
8733 * configure.in (ALL_LINGUAS): Added complete list of translations:

8822 * src/macro.c (collect_arguments): Cast obstack arguments to
8823 (voidstar), so avoiding compiler warnings.
8824 Reported by Joseph E. Sacco.

8845 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
8846 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler

8913 Reported by David MacKenzie.
8915 1994-10-01 François Pinard <pinard@iro.umontreal.ca>

8921 1994-09-23 François Pinard <pinard@iro.umontreal.ca>
8923 * src/stackovf.c: Declare the handler_t typedef earlier in the

8926 casting sigsegv_handler.
8927 Reported by Robert Bernstein.
8929 * src/m4.c (main): Initialize program_name to argv[0] without

8954 Reported by Karl Berry.
8956 * Makefile.in (distclean, realclean): Instead of recursively
8957 calling $(MAKE) for the -local part, allow parallel execution of
8958 -recursive and -local, only delay the removal of config.status,
8959 which is repeated in both goals.
8961 1994-09-13 François Pinard <pinard@iro.umontreal.ca>
8965 * Makefile.in: Group all *clean-recursive goals in one, using sed
8966 to remove `-recursive' while calling make recursively. Also, use

8994 1994-09-08 François Pinard <pinard@iro.umontreal.ca>
8996 * Makefile.in (MDEFINES): Remove INSTALL substitutions, for
8997 ./install.sh will not be correctly referred to in sub-Makefiles.
8998 Reported by John David Anglin.
9000 * doc/Makefile.in (texclean): Remove *.cps and *.fns too.

9032 * src/m4.c: Have -P set prefix_all_buitins variable instead of
9033 calling a function by that name. Declare the variable.
9034 * src/m4.h: Adjust declaration for prefix_all_buitins.
9035 * src/builtin.c (builtin_init): Merge in functionality from
9036 previous prefix_all_buitins function, while making entries in the
9037 symbol table, but not modifying the builtin description itself.
9039 * src/freeze.c (reload_frozen_state): Add a useless `break;',
9040 because *many* compilers do not accept an empty `default:'.

9054 functions, for implementing a global MAXIMUM_TOTAL_SIZE instead of
9055 a per buffer MAXIMUM_BUFFER_SIZE.
9057 * src/output.c (output_text): New function, for optimizing the
9058 output of strings of characters. Use it.
9060 1994-08-30 François Pinard <pinard@iro.umontreal.ca>

9065 * Makefile.in: Adjusted.
9066 * configure.in: Configure new Makefiles.
9068 * m4.h: Declare STRING typedef. Use it for comment and quote
9069 strings, adjusting all references. (This is the rudiments of a
9070 beginning for the eventual withdrawal of NUL terminated strings.)
9071 * output.c (shipout_text): Accept a length parameter, and use it.
9072 All callers adjusted.
9074 1994-08-29 François Pinard <pinard@iro.umontreal.ca>
9076 * m4.h: Include <unistd.h> if it exists.
9077 * stackovf.c: Don't.

9091 * m4.h, m4.c: Remove NDIVERSIONS and ndiversion related stuff.
9092 * m4.c: Still accept -N, but do nothing with it.
9093 Reported by David MacKenzie.
9096 * output.c (freeze_diversions): New function.
9097 * m4.h: Declare freeze_diversions.
9098 * freeze.c: Document frozen file format, revise it, call
9099 freeze_diversions to add diversions to frozen format, and code to
9100 reload them properly.
9101 * m4.c: Do not undivert automatically at end when status being
9102 frozen. Do not call builtin_init when reloading frozen state.
9104 Speed up diversion processing:
9105 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
9106 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
9107 structure and variables, cached variables out of output_diversion,
9108 reallocate_diversion_for and OUTPUT_CHARACTER.
9109 (shipout_text, make_diversion, insert_diversion): Adapted to new

9117 dist works from another build directory.
9119 1994-08-27 François Pinard <pinard@iro.umontreal.ca>
9121 * symtab.c (hack_all_symbols): Use hash_table_size instead of
9122 constant HASHMAX, for -H option to work better.
9124 * builtin.c (DECLARE): Simplify by using _ ().
9126 * freeze.c: New file.
9127 * Makefile.in: Compile it, distribute it.
9128 * m4.c: Recognize, document and process --freeze-state (-F) and
9129 --reload-state (-R) options. Pass a true flag to builtin_init
9130 only if no reloading some state.
9131 * builtin.c (define_builtin): Remove static specifier.
9132 (find_builtin_by_name): Remove static specifier.

9148 Reported by Akiko Matsushita.
9150 1994-08-12 François Pinard <pinard@iro.umontreal.ca>
9152 * m4.h: Include <sys/types.h>.
9153 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
9154 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
9156 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
9158 * builtin.c (dump_args): Declare len as size_t, not int.
9160 * debug.c: Prototype the forward declaration of debug_set_file.
9162 * builtin.c (m4_undivert): Replace div by file, for avoiding the
9163 shadowing of this variable.
9164 * output.c (insert_diversion): Idem.
9166 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
9167 (input_init): Duplicate default quote and comment strings.

9174 * Makefile.in (distclean-local): Also delete config.cache.
9176 * m4.c (usage): Reorganize the --help output by topic. Include a
9177 description for debugging flags.
9179 1994-07-29 François Pinard <pinard@iro.umontreal.ca>
9181 * configure.in: If sigaction is available and SA_ONSTACK defined,
9182 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
9183 defined, use sigvec. Else don't compile stackovf.c.
9184 * stackovf.c (setup_stackovf_trap): Idem.
9185 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
9188 1994-07-21 François Pinard <pinard@iro.umontreal.ca>
9190 * m4.c (usage): Replace printf par fputs.
9192 1994-07-18 François Pinard <pinard@iro.umontreal.ca>
9196 1994-07-17 François Pinard <pinard@iro.umontreal.ca>
9198 * configure.in: Check for sigaction and sigvec. Add a new delayed
9199 check for RLIMIT_STACK, combine in the checking for getrlimit.
9200 All those things are not universally available.
9201 * stackovf.c: Split setting up the trap handler and catching
9202 signals, for better taking care of various configure outcomes.
9203 * examples/stackovf.sh: Correct a typo.
9204 Reported by Eric Backus, Jim Avera and Jim Meyering.
9206 1994-07-16 François Pinard <pinard@iro.umontreal.ca>
9208 * ansi2knr.c: New version sent by its author, Peter Deutsch.
9210 1994-07-15 François Pinard <pinard@iro.umontreal.ca>
9212 * Makefile.in: Modify so parallel make will not try making
9213 lib/libm4.a twice simultaneously.
9214 Reported by Jim Meyering.
9216 1994-07-14 François Pinard <pinard@iro.umontreal.ca>
9218 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
9219 error message, for when no code possibility exists. Even if this
9220 line is completely #ifdef'ed out, it brings a syntax error.
9221 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
9223 * Makefile.in (install): Have install depend on all too, for lib
9224 to be remade as needed.
9226 * examples/stackovf.sh: Try ksh, bsh and bash for shells
9227 providing ulimit, instead of using only ksh.
9228 Reported by Jim Avera and Joseph E. Sacco.
9230 1994-07-12 François Pinard <pinard@iro.umontreal.ca>
9232 * Makefile.in (check): Have it depend on all instead of m4. In
9233 this way, a change in lib will be detected and processed.
9235 * builtin.c (numeric_arg): Use strtol and verify the conversion,
9236 instead of using sscanf which stops as soon as there is a
9237 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
9238 and divert(1xyzzy) were all accepted without any warning or error
9240 * m4.h: Declare strtol as long if not including stdlib.h.
9241 * configure.in: Check for limits.h, and replace strtol if missing.
9242 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
9243 * lib/strtol.c: New file, from elsewhere.
9244 Reported by Andreas Schwab.
9246 1994-07-07 François Pinard <pinard@iro.umontreal.ca>
9248 * macro.c (expand_macro): Cast value to (boolean) prior to
9249 assigning it to traced.
9250 Reported by Tom McConnell.
9252 * Makefile.in (m4): Always make all in lib first.
9253 Reported by Jim Meyering.
9255 1994-07-06 Jim Avera <jima@netcom.com>
9257 * stackovf.c: Isolated OS-dependent sections; Improved portability,
9258 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
9259 handlers), and a default error message if the fault address is not
9260 available (when neither siginfo.h nor BSD sigcontext are supported).
9261 * configure.in: Changes for stackovf.h: Check for sigcontext,
9262 sigaction, sigstack, and define rlim_t as int if necessary.
9263 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
9264 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
9265 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
9267 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
9269 * configure.in: Use AC_SET_MAKE.
9270 * Makefile.in: Use @SET_MAKE@.
9271 Reported by Jim Meyering.
9273 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
9274 Reported by Ian Taylor.
9276 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
9278 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
9279 because siginfo.h is unrelated to standard headers, and siginfo.h
9280 is already checked for.
9281 Reported by Joseph E. Sacco.
9283 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
9285 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
9288 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
9290 * builtin.c (substitute): Use \& to represent this part of the
9291 string which was matched by the whole regexp, instead of
9292 representing the whole string. Any usage of \0 issues a warning
9293 and acts like \&, it will disappear in some subsequent release.
9295 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
9297 * m4.c: Complete prototype for forwarded declaration of usage.
9299 * input.c (init_macro_token): Correct own reference in error
9300 message. Previous name get_macro_func was referred to instead.
9301 (next_char): Correct own reference in error message. Previous
9302 name advance_input was referred to instead.
9304 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
9305 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
9306 and_term, not_term, logical_not_term, cmp_term, shift_term,
9307 add_term, mult_term, exp_term, unary_term, simple_term): Add
9308 prototype to forwarded declarations. Declare parameter v1 as
9309 eval_t * instead of int *. Same for local variable v2 in dyadic
9310 functions. Same for result in exp_term.
9311 * builtin.c (m4_eval): Declare value as eval_t instead of int.
9312 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
9313 unsigned_eval_t instead of unsigned int. Change casts accordingly.
9314 (shipout_int): Cast first argument of ntoa to eval_t.
9315 Reported by Thorsten Ohl.
9317 * macro.c: Complete the prototypes of forwarded expand_macro and
9319 Reported by Thorsten Ohl.
9321 * m4.h: Define voidstar as void * or char * depending on __STDC__.
9322 The Ultrix 3.1 compiler cannot do much with void pointers.
9324 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
9325 * m4.c (xfree): Replace void * by voidstar.
9326 Reported by Tom McConnell.
9328 * ansi2knr.1: New, from elsewhere.
9329 * Makefile.in (DISTFILES): Distribute ansi2knr.1
9331 * Makefile.in (stamp-h.in): Avoid running ./config.status if
9332 stamp-h does not exist yet. This avoids running it a second time
9333 just after the initial ./configure.
9334 Reported by David MacKenzie and Tom McConnell.
9336 * m4.h: Replace the enum debug_info declaration with a series of
9337 #define's. The Ultrix 3.1 compiler would otherwise need casting
9338 (int) to most references, when used in expressions.
9339 Reported by Tom McConnell.
9341 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
9343 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
9344 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
9345 calls the compiler. Previously, FP_PROTOTYPES was only calling
9346 the preprocessor; by not being subject to CFLAGS, this was
9347 discouraging those flags asking for ANSI compilation.
9348 * acconfig.h: Document HAVE_PROTOTYPES.
9349 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
9350 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
9351 Reported by Eric Backus.
9353 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
9354 from the environment. Default CFLAGS to -g if not set.
9355 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
9356 * lib/Makefile.in: Have CFLAGS substituted from configure.
9357 Reported by Eric Backus and Tom McConnell.
9359 * configure.in: m4_undefine changeword before using AC_ENABLE.
9361 * m4.h: Declare prototypes for error (for ANSI compilers only),
9362 prefix_all_builtins and reference_error.
9363 Reported by Tom McConnell.
9365 * input.c (set_word_regexp): Do not try to initialize the array
9366 test from a string, this does not work with non-ANSI compilers.
9367 Reported by Eric Backus.
9369 * Makefile.in (dist): Clean examples/ before saving it.
9370 (distclean-local): Also remove stamp-h.
9371 Reported by Eric Backus.
9373 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
9375 Reported by Tom McConnell.
9377 * checks/Makefile.in (clean): Depends on mostlyclean.
9378 (mostlyclean): New goal.
9380 1994-06-24 François Pinard <pinard@iro.umontreal.ca>
9382 * Makefile.in (DISTFILES): Distribute install.sh.
9383 * install.sh: New file, copied from elsewhere.
9384 Reported by Assar Westerlund and Kaveh R. Ghazi.
9386 1994-06-23 François Pinard <pinard@iro.umontreal.ca>
9388 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
9389 * acconfig.h: Explain ENABLE_CHANGEWORD.
9391 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
9392 from code provided by Pete Chown]
9393 * m4.h: Add original_text field to u_t variant of union u.
9394 Declare TOKEN_DATA_FUNC macro.
9395 * builtin.c: Declare changeword.
9396 (m4_changeword): New function.
9397 * input.c: Include "regex.h", define variables with word regexps.
9398 (input_init): Initialize the word regexp.
9399 (set_word_regexp): New.
9400 (next_token): Declare local variables, use the previous code if
9401 default_word_regexp is true. Else, match using a new code. Save
9403 * macro.c (expand_token): Ship out original text if not a macro
9405 Reported by Krste Asanovic and Pete Chown.
9407 [These modifs all depend upon ENABLE_CHANGEWORD]
9408 * m4.h: Declare external user_word_regexp.
9409 * m4.c: Declare user_word_regexp, and initialize it from
9410 --word-regexp or -W, or NULL if not specified.
9411 * input.c: Use user_word_regexp if specified, instead of
9412 DEFAULT_WORD_REGEXP.
9414 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
9417 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
9418 * checks/Makefile.in: Empty the suffix list.
9419 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
9421 * m4.c: Declare nesting_limit and initialize it to 250.
9422 Implement -LNUMBER or --nesting-limit=NUMBER to change its
9424 * m4.h: Declare nesting_limit as external.
9425 * macro.c (expand_macro): Stop execution whenever nesting limit
9427 Reported by Bengt Mertensson.
9429 * eval.c (evaluate): Diagnose excess characters in eval input.
9430 Things like `eval(08)' used to return 0 with no diagnostic.
9432 * m4.h: Capitalize first letter of all macro arguments in
9435 * m4.c: Declare warning_status, initialize it to 0. Add new
9436 option -E, or --fatal-warnings, which sets warning_status to
9437 EXIT_FAILURE instead.
9438 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
9439 EXIT_FAILURE if not otherwise done by header files.
9440 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
9441 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
9442 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
9443 argument of all M4ERROR calls.
9444 Reported by Noah Friedman.
9446 * examples/incl-test.m4: Renamed from incl_test.m4.
9447 * examples/include.m4: Include incl-test.m4 instead of
9449 * examples/multiquotes.m4: Renamed from multi-quotes.m.
9451 1994-06-22 François Pinard <pinard@iro.umontreal.ca>
9453 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
9454 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
9455 also tested it on a Sun Sparc workstation running SunOS 4.x.
9457 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
9458 49.format check, abusing a `union values' argument with sprintf
9459 without selecting the proper field. Now, save the formatting type
9460 first, delaying the fetch of the corresponding argument.
9461 Reported by Joseph E. Sacco and Tom Quinn.
9463 * format.c (format): Remove const from char *fmt declaration when
9464 not HAVE_EFGCVT, because a NUL may be forced into it.
9466 * m4.h: Declare atof() when not STDC_HEADERS.
9467 Reported by Joseph E. Sacco.
9469 * Regenerate configure using Autoconf 1.11, this corrects a
9470 problem about an incorrect cpp seting on NeXT 3.1.
9471 Reported by Alexander Lehmann.
9473 1994-06-05 François Pinard <pinard@iro.umontreal.ca>
9475 * m4.h (_): Change argument from `x' to `Args'.
9477 1994-04-22 François Pinard <pinard@iro.umontreal.ca>
9479 * m4.h: Rename Args() to _().

9485 * configure.in: Check for getrlimit, sigaction. If all of
9486 standard headers, getrlimit and sigaction, define USE_STACKOVF and
9487 substitute ${U}stackovf.o for STACKOVF.
9488 * acconfig.h: Declare USE_STACKOVF.
9489 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
9490 * m4.h: Declare setup_stackovf_trap().

9496 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
9498 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
9500 1994-01-30 François Pinard <pinard@iro.umontreal.ca>
9502 * m4.h: Remove definition of volatile, not used anymore.
9503 Reported by Jim Meyering and Joseph E. Sacco.
9505 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
9506 of `if ... else /* nothing */' for if macros.
9507 Reported by Jim Meyering.
9509 * builtin.c (m4_regexp): Reorganize the code for avoiding a
9510 warning from gcc about `repl' possibly used before defined.
9511 Reported by Jim Meyering.
9513 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
9514 Reported by Jim Meyering.
9516 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
9518 * m4.h: Move the conditional definition of volatile after the
9519 inclusion of system files, because they may define it first.
9521 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
9523 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
9524 get around a problem with Alpha make seeing a syntax error, there.

9540 * m4.c: Initialize show_help and show_version to zero.
9542 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
9543 Use them in exit() and usage() calls.
9545 1993-11-27 François Pinard <pinard@iro.umontreal.ca>
9547 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
9548 syserr() macro. Delete errref, add reference_error and M4ERROR.
9549 * m4.c: Replace errref, which was returning an input reference
9550 string, with reference_error, which prints it on standard error.
9551 * builtin.c, output.c: Use errno as second parameter to error,
9552 instead of using syserr() with %s.
9553 * *.c: Use M4ERROR instead of error: no more errref() with %s.
9554 Doing so, the program name appears after the input reference
9555 instead of before, which eases M-x next-error processing.
9557 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
9559 * checks/get-them: Escape braces with backslashes in patterns,
9560 because HPUX-9.01 awk needs this.

9571 * *.c: Use error() systematically in place of all error macros,
9572 now that error() flushes stdout first. Make needed adjustments.
9574 * m4.h: Remove const in sys_errlist[] declaration, it creates
9575 conflicts on SGI and Alpha.
9576 Reported by Kaveh R. Ghazi.

9596 * input.c (input_init): Initialize quote and comment strings
9597 explicitely instead of calling set_quotes and set_comment: by
9598 doing so, we ensure we do not free uninitialized variables.

9601 expected is on the left and the obtained on the right.
9603 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
9604 macros. Delete declarations for m4error, warning, fatal and
9605 internal_error, add declaration for error_message_prefix.
9606 * m4.c: Delete m4error, warning, fatal and internal_error
9607 routines, add error_message_prefix routine.
9608 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
9609 warning with WARNING*, fatal with FATAL* and internal_error with
9611 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
9612 this is not needed anymore.
9614 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
9615 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
9616 and debug_message, add declaration for debug_message_prefix.

9618 Delete debug_print and debug_message routines, add
9619 debug_message_prefix routine.
9620 * builtin.c, debug.c: Replace debug_print routine calls with
9621 DEBUG_PRINT* macro calls.

9627 (trace_format): Use stdarg instead of varargs if __STDC__.
9629 * configure.in: Remove checks for vfprintf and _doprnt. These
9630 implementations use varargs tricks which are not portable enough.

9653 Reported by Joel Sherrill.
9655 * builtin.c (prefix_all_builtins): Instead of the table size, use
9656 the null entry at end for stopping the loop. It was overwritten.
9657 Reported by Andreas Schwab and Jim Meyering.
9659 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
9660 Reported by Kaveh R. Ghazi.

9739 Reported by Jim Avera.
9741 * builtin.c (m4_ifelse): Diagnose excess arguments if 5, 8, 11,
9742 etc., arguments, then ignore the superfluous one. m4 used to
9743 diagnose missing arguments and return the empty string.

9915 * lib/alloca.c: New, from elsewhere.
9916 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
9918 * m4.h: Do not define index/rindex if already defined. If
9919 FALSE/TRUE are already defined, do not redefine them, but merely
9920 define boolean typedef to int.
9922 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
9923 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
9924 because some C compilers do not like connectives with #ifdef.

9926 __GNUC__ and once for __STDC__.
9927 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
9929 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
9930 Makefile dependencies. Without it, make keeps destroying and
9931 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
9933 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
9934 to diversion/DIVERSION, this was a spelling error.

9938 * Makefile.in: Remove references to version.h.
9940 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
9941 production, by using a simpler and more robust algorithm. This
9942 solves the problem of synclines sometimes written in the middle of
9943 an output line. Delete sync_line() and output_lines variable.
9944 * m4.h: Remove sync_line prototype and output_lines declaration.
9945 * input.c (next_char), output.c (shipout_text): Remove references
9947 * input.c (push_file, pop_file): Merely put the value -1 in
9948 output_current_line instead of calling sync_line, for delaying a
9949 single `#line NUM FILE' before next output line. Do not test
9950 for sync_output, because this is unnecessary clutter.
9951 * output.c (make_divertion, insert_divertion): Idem.
9952 * input.c: Rename must_advance_line to start_of_input_line, for
9955 * debug.c (trace_header): Select a new debug line format, which
9956 better complies with GNU standards for formatting error messages.
9957 With option `-dfl', M-x next-error might be used on the output.
9958 * m4.c (vmesg): Adjust format of error output to GNU standards.
9959 * m4.texinfo: Adjust examples for `make check' to work.
9961 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
9962 case for enum debug_info constants, which were all lower case.
9964 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
9966 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
9967 collected patches. I tried a few times using newer regex.[ch], it
9968 mysteriously stopped aborting with this one. Insecure feeling...
9969 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
9971 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
9973 * m4.c: Change `--no-warnings' to `--silent'.
9974 Reported by David MacKenzie.
9976 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
9977 leave it off for now. See comment in m4.c for justification.
9978 Reported by David MacKenzie.
9980 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
9981 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
9983 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
9985 * Makefile.in: Ensure recursive cleaning is done before local
9986 cleaning for all clean goals.
9988 * builtin.c (ntoa): Ensure the value is always interpreted as a
9989 signed quantity, whatever the radix is.
9991 1992-11-18 Jim Meyering <meyering@idefix>
9993 * builtin.c, format.c, input.c: Split long lines.
9994 * m4.c: Use typedef macro_definition instead of struct
9996 * symtab.c: Use typedef symbol instead of struct symbol.
9998 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
10000 * *.[ch]: Remove all trailing whitespace, in code and comments.
10002 * configure.in: Find some awk.
10003 * Makefile.in: Add $(AWK) to MDEFINES.
10004 * checks/Makefile.in: Transmit $(AWK) to get_them.
10005 * checks/get_them: Use $AWK instead of gawk. Add a close in the
10006 awk script when switching files, because without this, mawk runs
10007 out of file descriptors.
10009 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
10011 * Makefile.in (realclean): Delete m4.info*.

10019 recognizable by next-error, also use a better message.
10021 1992-11-16 Jim Meyering <meyering@idefix>
10023 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
10024 And use that only if __GNUC__ since we're using it's GCC-specific
10025 semantics that tell the compiler the associated function doesn't
10028 * builtin.c (substitute): Don't use character as an array index.
10029 (dumpdef_cmp): Make formal arguments `const void *' to avoid
10030 warnings with gcc -W -Wall on systems with qsort prototype.
10031 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
10034 * eval.c (most functions): Add parentheses to assignments used
10035 as truth values go avoid warnings from gcc -Wall.
10037 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
10038 any functions that don't need external scope.
10040 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
10041 (many functions and arrays): Declare `const'.
10043 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
10045 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
10046 removing the declaration from m4.h. Also rename false to FALSE
10049 * lib/Makefile.in (Makefile): New goal.
10051 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
10052 so heavily loaded. It gets more easily overridable, calling make.
10053 Reported by Jim Meyering.
10055 * Makefile.in (dist): Get .fname from the current directory name,
10056 instead of from version.h. I need updating many files manually,
10057 when the version changes, version.h is just one of them.
10059 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
10061 * m4.h: Remove the tag `boolean' on the enum introducing typedef
10062 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
10063 Reported by Tom McConnell.
10065 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
10067 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
10068 39.cleardiv, which were describing missing or spurious newlines.
10069 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
10070 do not depend on machine word size, `/bin/false' implementation,
10071 or `wc' output format. `make check' is more dependable, now.
10073 * checks/check_them: Summarize the failed tests by listing their
10074 name, at end. If none, issue `All checks successful'. Output
10075 `Checking' instead of `Input file:'.
10077 * checks/get_them, checks/check_them: Reindented.
10079 * Makefile.in (dist): chmod a+r before making the tar file.
10081 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
10083 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
10085 * input.c (next_token): Reinitialize token_buttom just after using
10086 it as a watermark with obstack_free. Or else, a future token, big
10087 enough for triggering reallocation of the obstack chunk, could
10088 void the initialized value of token_buttom, later causing panic in
10089 obstack_free. Rename token_buttom to token_bottom everywhere.
10091 * m4.h: Before declaring errno, first include <errno.h> and
10092 ensure that it does not define errno.
10093 Reported by Richard Stallman.
10095 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
10097 * builtin.c: Define and use DECLARE macro for builtins.
10099 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
10100 argument, this is a common idiom for introducing long comments.
10102 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
10103 arguments. The last argument was silently ignored.
10105 * m4.c (cmd_error): Add a missing semicolon before va_end().
10107 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
10109 * Makefile.in: Now handle protoized sources. Define and use U.
10110 Compile and use ansi2knr with old compilers. Update DISTFILES.
10111 Add `aclocal.m4' to `configure' dependencies.
10112 * ansi2knr.c: New, from Ghostscript distribution.
10113 * configure.in: Define U through FP_PROTOTYPES for old compilers.
10114 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
10115 * aclocal.m4: New, provide FP_PROTOTYPES.
10116 * m4.h: Conditionnaly protoized through Args, save for varags.
10117 * builtin.c: Protoized. Then:
10118 Include <sys/types.h> if size_t is not defined, before "regex.h".
10119 (m4_ifelse): Fetch built-in name properly for diagnostic.
10120 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
10121 (m4_regexp): Add const to `msg' declaration.
10122 (m4_patsubst): Add const to `msg' declaration.
10123 * debug.c: Protoized, save for varargs.
10124 * eval.c: Protoized.
10125 * format.c: Protoized.
10126 * input.c: Protoized.
10127 * m4.c: Protoized, save for varargs. Then:
10128 (xfree): Accept void * instead of char *.
10129 (xmalloc): Return void * instead of char *.
10130 (xrealloc): Accept and return void * instead of char *.
10131 * macro.c: Protoized.
10132 * output.c: Protoized.
10133 * path.c: Protoized. Then cast some (char *) over xmalloc's.
10134 * symtab.c: Protoized.
10136 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
10138 * m4.texinfo: Remove directory from diagnostics in 30.include,
10139 51.eval, 56.errprint and 57.m4exit tests.
10141 * m4.h: Remove declarations for int or void system functions, they
10142 cause more conflicting trouble than they make good.
10144 * configure.in: Avoid configuration header file. Add some tests.
10145 * m4.h: Remove #include "config.h".
10146 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
10147 Then, rewritten for better compliance with GNU standards.
10149 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
10151 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
10152 because of a misplaced #endif.
10154 * Many *.[hc] files: Correct intra-line spacing here and there,
10155 according to GNU indent 1.6 advice.
10157 * configure.in: New, using Autoconf 1.2.
10158 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
10159 * Delete old configure.in, configure, etc/configure.in,
10160 etc/configure, lib/configure.in, lib/configure and config/*.
10161 Reported by Jason Merrill.
10163 * symtab.c (hash): Change (char) NULL to '\0'.
10164 Reported by Jason Merrill.
10166 * Delete .vers, etc/newdist.sh, etc/newvers.sh and
10167 etc/nextvers.sh. Release numbers will be edited `by hand'.
10168 * version.h: De-automatize, force value in.
10170 * m4.c: Changes in order to use a newer getopt.h.
10171 Reported by David MacKenzie.
10173 * checks/: New name for examples/.
10174 * checks/get_them: New location for etc/get_examples.
10175 * checks/check_them: New location for etc/check_examples.

10199 code disposition by hand.
10201 1992-03-08 François Pinard <pinard@iro.umontreal.ca>
10203 * m4.h: Delete definitions for abort() and exit().
10204 Reported by Richard Stallman.
10206 * config/hmake-unicos, config/s-unicos.h: New files.
10207 Reported by Hal Peterson.
10209 * eval.c (exp_term): Have N^0 return 1.

10220 reports and feedback.
10222 * Uses GNU configure, taken from the gdb distribution.
10224 * Uses GNU getopt(), with long option names.
10226 * The -Q/+quiet option is added, which suppresses warnings about
10227 missing or superflous arguments to built-in macros.
10229 * Added default options via the M4OPTS environment variable.
10231 * The built-in format can now be configured to use sprintf as
10232 the formatting engine, for systems without [efg]cvt(3).
10234 * GNU library code is moved to the ./lib subdirectory; other
10235 utility files are now in ./etc.
10237 * Several minor bugs have been fixed.
10239 1991-07-26 René Seindal <seindal@diku.dk>
10241 * Fixed various bugs. Release 0.99, manual 0.09. Many thanks to
10242 François Pinard and Roland H. Pesch for providing me with reports.
10244 * The builtins incr and decr are now implemented without use of
10247 * The builtin indir is added, to allow for indirect macro calls
10248 (allows use of "illegal" macro names).
10250 * The debugging and tracing facilities has been enhanced
10251 considerably. See the manual for details.
10253 * The -tMACRO option is added, marks MACRO for tracing as soon
10256 * Builtins are traced after renaming iff they were before.
