265 instead, for consistency with gnulib bootstrap.
266 (func_get_translations): Use rsync, not wget.
267 (func_update_po): Use a reference directory, to avoid changing
268 timestamps on unchanged .po files.

497 immediately on overflow.
498 * tests/freeze.at (loading format 2): Test this.
499 Reported by Jim Meyering.
501 2008-05-08 Eric Blake <ebb9@byu.net>
503 Stage 23: allow tracing of indirect macro calls.
504 Track all trace information as part of the argv struct, rather
505 than temporarily resetting global state. Teach indir to trace

508 Speed impact: none noticed.
509 * m4/m4module.h (m4_input_block): Remove.
510 (m4_call_info): New opaque type.

544 * NEWS: Mention these changes.
545 Reported by Akim Demaille in the autoconf TODO file in 2000.
547 2008-05-07 Eric Blake <ebb9@byu.net>
549 Test for traceon regression just fixed in branch-1.6.

551 * NEWS: Port news item from branch.
553 2008-05-05 Eric Blake <ebb9@byu.net>
555 Stage 22: allow builtin token concatenation outside $@.
556 Adjust the input and argument parsing engines to append builtins
557 alongside text. Make define warn when builtins must be
559 Memory impact: slight penalty, with fewer builtins flattened.
560 Speed impact: slight penalty, from more bookkeeping.
561 * m4/m4module.h (m4_is_arg_composite): New prototype.
562 (m4_symbol_value_copy): Change return type.
563 (m4_arg_text): Add parameter.

632 spurious write failure.
633 * src/main.c (main): In batch mode, restore default handling of
635 * doc/m4.texinfo (Operation modes): Document SIGPIPE behavior.
637 Reported by Bob Proulx, via his autobuilder.
639 2008-04-15 Eric Blake <ebb9@byu.net>
641 Fix 'make installcheck' after './configure --prefix-progname'.
642 * tests/testsuite.at (AT_CHECK_M4): Allow overriding the m4

651 (DISTCHECK_CONFIGURE_FLAGS): Ensure no regressions, by using gm4
652 during 'make distcheck'.
653 * cfg.mk: New file, borrowed from branch.
655 Update prerequisite tools to match recent releases.
656 * configure.ac (AC_PREREQ): Rely on released autoconf.
657 (LT_PREREQ): Rely on released libtool.
658 * tests/testsuite.at (m4_version_prereq): Update dependence.
659 * bootstrap: Mention prerequisites.
661 Work around OS/2 limitation of printf(1).
662 * tests/null.m4: Use m4, not printf, to generate NUL byte.
663 * tests/null.out: Check for esyscmd failure.
664 Reported by Elbert Pol.
666 2008-04-14 Eric Blake <ebb9@byu.net>
668 Stage 21b: $@ concatenates builtins, m4wrap takes builtins.
669 Improve arg_print to handle builtin tokens when printing to a
670 known chain, rather than always flattening builtins. This allows
671 m4wrap and $@ back-references to handle embedded builtin tokens.
673 Speed impact: slight penalty, from more bookkeeping.
674 * m4/m4module.h (m4_push_builtin): Add parameter.
675 (m4_builtin_print, m4_push_wrapup_init, m4_push_wrapup_finish)
676 (m4_arg_print, m4_symbol_value_print): Rename and reduce scope...
677 * m4/m4private.h (m4__builtin_print, m4__push_wrapup_init)
678 (m4__push_wrapup_finish, m4__arg_print, m4__symbol_value_print):
679 ...to these, in some cases adding a parameter.
680 (m4__append_builtin): New prototype.
681 * m4/builtin.c (m4_builtin_print): Alter signature to print
682 builtin to a growing symbol chain.
683 * m4/symtab.c (m4__symbol_value_print): Alter signature.
684 (m4_symbol_print, dump_symbol_CB): Adjust callers.
685 * m4/input.c (builtin_peek, builtin_read, builtin_unget)
686 (builtin_print, builtin_funcs): Delete, handled via composite
688 (struct m4_input_block): Delete u.builtin member.
689 (init_builtin_token): Only use composite block.
690 (m4__append_builtin): New function.
691 (m4_push_builtin, m4__push_wrapup_init): Alter signature.

702 * modules/gnu.c (builtin): Likewise.
703 * doc/m4.texinfo (M4wrap): New test.
704 (Debuglen): Adjust expected output.
706 Stage 21a: Optimize checks for end of input.
707 Create a new polymorphic input block type, which always fails with
708 CHAR_EOF, so that remaining input routines no longer have to check
709 for NULL input block.
711 Speed impact: noticeable improvement, from fewer conditionals.
712 * m4/input.c (eof_funcs, input_eof): New objects.
713 (eof_peek, eof_read, eof_unget): New functions.
714 (file_clean, m4_push_string_init, pop_input, m4_push_wrapup_init)
715 (m4_pop_wrapup, next_char, peek_char, unget_input, m4_input_init)
716 (m4_input_exit): Use placeholder to guarantee non-NULL isp and
718 (next_char): Rename retry to allow_unget, and change sense for
719 easier manipulation. All callers changed.
721 Improve OS/2 detection.
722 * modules/gnu.c (m4_macro_table): Ensure all possible identifiers
723 are defined, not just the first. The testsuite ensures that
724 exactly one gets defined.
725 * m4/system_.h [__EMX__]: OS/2 is not Unix-compatible, no matter
726 what other pre-defined macros it has.
728 Reported by Elbert Pol.
730 Ensure __m4_version__ is unquoted.
731 * tests/builtins.at (__m4_@&t@version__): Augment test.
733 Avoid GNU make failure on tarball.
734 * Makefile.am (EXTRA_DIST): Distribute cfg.mk and maint.mk.
736 2008-04-10 Eric Blake <ebb9@byu.net>

740 * m4/utility.c (m4_symbol_value_lookup): Change signature.
741 * modules/m4.c (undefine, popdef, ifdef, m4_dump_symbols, defn):
743 * tests/others.at (ifndef): New test.
745 Be namespace clean for M4 version; fixes 2008-04-08 regression.
746 * configure.ac (version): Rename...
747 (M4_VERSION): ...to this, since using 'version' broke po.m4.
749 2008-04-09 Eric Blake <ebb9@byu.net>
751 Mention 1.4.11 release.
752 * doc/m4.texinfo (History, Defn, Ifdef, Ifelse, M4wrap)
753 (Extensions, Improved foreach): Distinguish 1.4.11 and 1.6.
754 (Format): Add test of C99 hex-float parsing.
755 * NEWS: Mention 1.4.11 release.
756 * tests/builtins.at (divert): Add additional test.
758 2008-04-08 Eric Blake <ebb9@byu.net>
760 Overhaul inter-version releases to work with git.
761 * configure.ac (version): New variable, which has nicer version
762 contents when using git 1.5.5+, hardcoded to 1.9a otherwise.
763 (TIMESTAMP): Delete, since CVS id expansion died with transition
765 (AM_INIT_AUTOMAKE): Use version to decide gnu vs. gnits.
766 * build-aux/mkstamp: Delete, no longer used.
767 * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Kill, to speed up
768 rebuilds when timestamps don't matter.
769 (MKSTAMP): Delete, no longer used.
770 (EXTRA_DIST): No longer worry about mkstamp.
771 (.version): New rule and distributed file.
772 (doc/m4.1, tests/package.m4): Depend on .version, not
773 configure.ac, for timestamp.
774 * ltdl/m4/gnulib-cache.m4: Import git-version-gen module.
775 * modules/gnu.c (__m4_version__): TIMESTAMP no longer exists.
776 * src/main.c (main): Likewise.
778 2008-03-28 Eric Blake <ebb9@byu.net>
780 Use GNUmakefile module.
781 * ltdl/m4/gnulib-cache.m4: Import gnumakefile module.
782 * Makefile.am: Split off maintainer rules...
783 * maint.mk: ...into this new file.
785 2008-03-18 Eric Blake <ebb9@byu.net>
787 Stage 20b: make m4wrap obey POSIX fifo ordering.
788 Improve input engine to support location changes within symbol
789 chains, then convert m4wrap to always build symbol chain.
791 Speed impact: slight penalty, from more m4wrap bookkeeping.
792 * m4/m4module.h (m4_wrap_args): Add prototype.
793 * m4/m4private.h (enum m4__symbol_chain_type): Add M4__CHAIN_LOC.
794 (struct m4__symbol_chain): Add struct u_l.
795 * m4/input.c (m4_push_wrapup_init, m4_push_wrapup_finish): Use
797 (composite_peek, composite_read, composite_clean): Handle location
799 * m4/macro.c (m4_wrap_args): New function.
800 * modules/m4.c (m4wrap): Use it.
801 * doc/m4.texinfo (M4wrap): Sync with branch and POSIX.
802 (Extensions): Document extension of multiple arguments.
803 (Location, Improved m4wrap): Adjust example to match FIFO order.
804 * tests/builtins.at (wrap): Likewise.
805 * NEWS: Document this change.
807 2008-03-17 Eric Blake <ebb9@byu.net>
809 Stage 20a: reduce unget's in input engine.
810 Now that out-of-range input placeholders like CHAR_BUILTIN are
811 consumed outside of next_char, next_token should always consume
812 rather than peek at the first character. Fewer peeks results in
813 less ungetc overhead.
815 Speed impact: noticeable improvement, from fewer function calls.
816 * m4/input.c (struct input_funcs): Alter read_func prototype.
817 (next_char, file_read, buildin_read, string_read, composite_read):
818 Add allow_argv parameter.
819 (init_builtin_token, init_argv_symbol): Require all prior input to
821 (m4_skip_line, match_input, consume_syntax): Adjust callers.
822 (m4__next_token): Consume first byte without peek.
824 Update for fresh bootstrap.

833 * doc/m4.texinfo (Improved m4wrap): New node.
834 (Defn, Location): Enhance tests.
835 (Shift): Document the composite macro join.
836 (Incompatibilities): Move documentation of LIFO vs. FIFO...
837 (M4wrap): ...here, to match improved example.
839 2008-03-13 Eric Blake <ebb9@byu.net>
841 Stage 19c: allow builtin tokens in more macros.
842 Allow builtin tokens inside symbol chains, although for now, they
843 are not allowed inside comments or quotes. Enable builtin token
844 handling in more macros, if only to consistently diagnose invalid
847 Speed impact: slight impact, due to more bookkeeping.
848 * m4/m4module.h (m4_symbol_value_lookup, m4_builtin_print): New
850 * m4/m4private.h (enum m4__symbol_chain_type): Add
852 (struct m4__symbol_chain): Add builtin member.

863 (collect_arguments, m4_arg_equal, m4_arg_print, m4_push_args):
864 Handle builtin tokens.
865 (arg_symbol): Add parameter, and allow NULL level.
866 (m4_arg_symbol, m4__push_arg_quote): Adjust callers.
867 (m4_arg_text): Ensure all builtins have been flattened.
868 * modules/m4.c (defn, dumpdef, popdef, traceoff, traceon)
869 (undefine, m4_dump_symbols): Warn on invalid macro names.
870 (ifdef, ifelse, shift): Handle builtin tokens.
871 * modules/gnu.c (m4symbols): Likewise.
872 * doc/m4.texinfo (Defn, Ifdef, Ifelse): Document and test the new
874 (Debuglen): Likewise, and remove xfail.
875 * NEWS: Mention the change.
877 Stage 19b: invert sense of bit for handling builtin tokens.
878 Pass builtin tokens by default, rather than as the exception, so
879 that the logic can consistently refer to flattening arguments.
882 * m4/m4module.h (M4BUILTIN_ENTRY): New convenience macro.
883 (M4_BUILTIN_GROKS_MACRO): Rename...
884 (M4_BUILTIN_FLATTEN_ARGS): ...and invert sense.
885 (m4_symbol_value_groks_macro, m4_symbol_groks_macro): Likewise...
886 (m4_symbol_value_flatten_args, m4_symbol_flatten_args): ...to

893 (m4_symbol_value_flatten_args): ...to this.
894 * m4/macro.c (collect_arguments): Accomodate changed sense.
895 * m4/module.c (m4__module_open): Require arguments if flattening
897 * m4/input.c (m4_push_string_finish): For now, flatten all
898 builtins pushed as back-references.
899 * modules/gnu.c (m4_builtin_table, builtin): Adjust all clients.
900 * modules/import.c (m4_builtin_table): Likewise.

908 * modules/m4.c (m4_builtin_table): Likewise.
909 (mkstemp): Undo #undef hack from 2006-10-23, now that macro names
910 are stringized without preprocessor expansion.
911 * doc/m4.texinfo (Defn): Update comments to match reality.
912 (Debuglen): Update test now that user macros pass builtin tokens.
914 Stage 19a: sort and cache builtins loaded by a module.
915 Rather than repeatedly using dlsym to browse the builtin table,
916 copy off the table at module load time. Then, the input engine
917 merely refers to the copy instead of duplicating information.
918 Memory impact: slight penalty, due to more memory per module, but
919 offset by less memory in input engine.
920 Speed impact: slight improvement, due to faster builtin lookups.
921 * m4/m4module.h (m4_set_symbol_value_builtin): Delete. Use
922 m4_builtin_find_by_* instead.
923 (m4_builtin_find_by_func): Change return type.
924 * m4/m4private.h (m4__builtin): New struct.
925 (m4_module): Add sorted list of loaded builtins.
926 (struct m4_symbol_value): Change type of builtin value.

941 (m4_builtin_find_by_func): Change return type.
942 * m4/input.c (struct m4_input_block): Simplify u_b, since most
943 fields can be determined from builtin.
944 (builtin_peek, builtin_read, builtin_unget, init_builtin_token)
945 (m4__next_token): Alter parsing so that only init_builtin_token
947 (builtin_print, m4_push_builtin): Adjust all users.
948 * tests/macros.at (Arity, defn, and freeze): Fix typo.
950 Consistently cast malloc results, for C++ compilation.
951 * m4/builtin.c (m4_builtin_find_by_name): Add cast.
952 * m4/hash.c (m4_hash_new, m4_get_hash_iterator_next, node_new)

984 2008-02-23 Eric Blake <ebb9@byu.net>
986 Stage 18: try harder to reuse argv in recursion.
987 When pushing arguments that contain an existing $@ ref, reuse the
988 ref rather than creating another layer of wrappers.
989 Memory impact: noticeable improvement, due to better $@ reuse.
990 Speed impact: noticeable improvement, due to O(n^2) to O(n)
991 reduction in unboxed recursion.
992 * m4/macro.c (make_argv_ref): Avoid wrapping $@ when possible.
993 (m4_push_args): Let make_argv_ref take care of pending data.
994 * doc/m4.texinfo (Improved foreach): Tweak wording to match new
995 performance capability.
996 * tests/others.at (recursion): Add tests to avoid performance
999 2008-02-22 Eric Blake <ebb9@byu.net>
1002 * NEWS: Document change to __gnu__ on 2008-02-11.
1004 Stage 17: pass argv through quoted strings.
1005 Allow the concatenation of $@ references with other text input
1006 inside quoted contexts, which requires distinguishing between a
1007 wrapper around many arguments vs. a reference serving as part of a
1008 single argument. Also optimize based on whether argv contains
1009 builtin tokens that might need flattening to the empty string.
1010 Memory impact: noticeable improvement, due to O(n^2) to O(n)
1011 reduction from total reuse of $@ references.
1012 Speed impact: noticeable improvement, due to O(n^2) to O(n)
1013 reduction in boxed recursion.
1014 * m4/m4module.h (m4_arg_equal, m4_arg_len): Add parameter.
1015 (M4ARGLEN): Adjust definition.
1016 * m4/m4private.h (struct m4__symbol_chain): Add has_func member.
1017 (struct m4_symbol_value): Add wrapper and has_func members.

1030 2008-02-22 Gary V. Vaughan <gary@gnu.org>
1032 Fix regression in argument collection, from 2008-01-21.
1033 * m4/input.c (m4__next_token): When DEBUG_INPUT is defined,
1034 undo argument collection optimisation for strings, so that
1035 m4_print_token doesn't abort when it otherwise receives an
1036 unprintable M4_SYMBOL_VOID type token.
1038 2008-02-20 Eric Blake <ebb9@byu.net>
1040 Stage 16: cache quotes and improve m4_arg_print.
1041 Cache rather than always copying quotes when pushing $@ refs; in
1042 particular, reconstruct single-byte quotes on the fly. Allow NUL
1043 through m4wrap. Improve sharing of code that prints arguments.
1044 Memory impact: slight improvement, due to cached quotes.
1045 Speed impact: slight improvement, due to less copying.
1046 * m4/m4module.h (m4_symbol_value_print, m4_symbol_print)
1047 (m4_arg_print): Adjust prototypes.

1059 (m4_symbol_print, dump_symbol_CB): Adjust all callers.
1060 * m4/utility.c (m4_dump_args): Delete; callers should use
1061 m4_arg_print instead.
1062 * m4/input.c (m4_push_wrapup_init, m4_push_wrapup_finish): Split
1063 implementation, and allow embedded NUL.
1064 (m4_print_token, pop_input, composite_print, composite_peek):
1065 (composite_read, append_quote_token): Adjust all callers.
1066 * m4/macro.c (trace_prepre, m4_arg_text, make_argv_ref):

1114 * doc/m4.texinfo (Improved forloop): Document advantage of $0.
1115 (Improved foreach): Adjust dump from file.
1117 Stage 15: return argv refs back to collect_arguments.
1118 Collect an entire $@ reference at once rather than one argument at
1119 a time, outside of quotes (but inside quotes, $@ is still
1120 flattened for now). The skip_last field allows concatenation of
1121 $@ with other text when collecting arguments.
1122 Memory impact: noticeable improvement, due to better reuse of $@.
1123 Speed impact: noticeable improvement, due to less parsing.
1124 * m4/m4private.h (CHAR_ARGV): New input engine sentinel.
1125 (enum m4__token_type): Add M4_TOKEN_ARGV.
1126 (struct m4__symbol_chain): Add skip_last member to argv link.

1224 Stage 14b: allow pushing argv references.
1225 Push a $@ reference to the input engine in one go, rather than
1226 pushing each element. For now, argument collection still gets one
1227 argument of a $@ at a time; but the penalties of this patch make
1228 it easier to manage $@ efficiently in future patches.
1229 Memory impact: noticeable penalty, due to larger struct and O(n)

1248 Stage 14a: allow printing argv references.
1249 Refactor symbol-value printing code for better sharing, and to

1259 to avoid infinite recursion in next patch.
1260 * m4/macro.c (trace_prepre, trace_pre): Adjust callers.
1261 (m4_arg_print): New function.
1262 * m4/symtab.c (m4_symbol_value_print): Update signature.

1315 Support pushing composite tokens, allowing back-references to be
1316 reused through multiple macro expansions. Add hueristic that

1403 * configure.ac (AM_INIT_AUTOMAKE): Require 1.10.1, and add lzma
1405 * bootstrap: Update automake requirement.
1406 (func_version): Fix --version output, broken since 2007-08-06.
1407 * HACKING: Likewise. Add lzma requirement.
1408 * Makefile.am (clean-local-src): Not needed any more with newest
1410 (clean-local): Adjust.
1411 * TODO: Remove completed item.
1413 2008-01-22 Eric Blake <ebb9@byu.net>
1416 * doc/m4.texinfo (Renamesyms): Avoid underfull hbox, and improve
1419 2008-01-21 Eric Blake <ebb9@byu.net>
1421 Stage 11: full circle for single argument references.
1422 Pass quoted strings through to argument collection in a single
1423 action, so that an argument can be reused throughout macro
1424 recursion if it remains unchanged.
1425 Memory impact: noticeable improvement, due to more reuse in
1426 argument collection stacks; O(n^2) to O(n) on boxed recursion.
1427 Speed impact: noticeable improvement, due to less copying.
1428 * m4/m4module.h (m4_arg_text): Add parameter.
1430 * m4/m4private.h (CHAR_QUOTE): New input engine sentinel.
1431 (m4__make_text_link): New prototype.
1432 (struct m4_symbol_chain): Add quote_age member.
1433 (struct m4_symbol_value): Add end member to chained symbol.
1434 (struct m4_macro_args): Add wrapper member.
1435 * m4/symtab.c (m4_symbol_value_print): Print composite tokens.
1436 (m4_symbol_value_copy, m4_symbol_value_delete): Recognize
1438 * m4/input.c (make_text_link): Rename...
1439 (m4__make_text_link): ...to this, and export.
1440 (m4_push_string_finish): Adjust caller.
1441 (make_text_link, m4__push_symbol): Update new field.
1442 (file_read, builtin_read, string_read, composite_read, next_char):
1444 (m4_skip_line, match_input, consume_syntax): Adjust callers.
1445 (append_quote_token): New function.
1446 (m4__next_token): Pass quoted strings onto argument collection.
1447 (m4_print_token) [DEBUG_INPUT]: Update.
1448 * m4/macro.c (expand_argument): Collect composite arguments.
1449 (collect_arguments): Update new field.
1450 (expand_macro): Reduce ref-count of back-references after use.
1451 (arg_mark, m4_arg_symbol, m4_make_argv_ref): Adjust to new member
1453 (m4_is_arg_text): Also recognize composite symbols as text.
1454 (m4_arg_text, m4_arg_len): Merge composite symbols as needed.
1455 (m4_arg_equal): Compare composite symbols.
1456 (m4_push_arg, m4_push_args): Handle composite symbols.
1457 (m4_arg_symbol): Relax assertion.
1458 (process_macro): Use single-argument references.
1459 * m4/output.c (m4_shipout_string_trunc): Update comment.
1460 * tests/macros.at (Rescanning macros): Augment test.
1462 2008-01-16 Eric Blake <ebb9@byu.net>
1464 Stage 10: avoid extra copying of strings and comments.
1465 When collecting tokens that are immune to further expansion, avoid
1466 copying data from one obstack to another by outputting it into the
1467 destination obstack to begin with. Also reduce copying done in
1469 Memory impact: slight improvement, due to better obstack usage.
1470 Speed impact: noticeable improvement, due less data copying.
1471 * ltdl/m4/gnulib-cache.m4: Import intprops and vasnprintf-posix
1473 * m4/m4private.h (m4__token_type): Adjust prototype.
1474 * m4/input.c (m4__next_token): Support new parameter.
1475 * m4/macro.c (m4_macro_expand_input, expand_token)
1476 (expand_argument, collect_arguments): Adjust callers.
1477 * modules/m4.c (ntoa): Tighten buffer size.
1478 * m4/output.c (m4_tmpname): Guarantee no buffer overflow.
1479 * modules/format.c (arg_int, arg_long, arg_double): New helper
1480 functions, to detect overflow or unparsed characters.
1481 (ARG_INT, ARG_LONG, ARG_STR, ARG_DOUBLE): Adjust to check for
1482 missing or excess arguments.
1483 (format): Likewise, and also output directly into obstack if there
1485 * doc/m4.texinfo (History): Update for new year.
1486 (Format): Test for new warnings.
1488 2008-01-15 Eric Blake <ebb9@byu.net>
1490 * TODO: Update with some newer URLs.
1492 Verify linear `index'.
1493 * tests/builtins.at (index): New test.
1494 (translit): Make test take longer, to make quadratic algorithms
1497 2007-12-20 Eric Blake <ebb9@byu.net>
1499 Stage 9: share rather than copy single-arg refs.
1500 Use hooks of previous patch to create back-references to arguments
1501 in the input engine, and inline short text rather than always
1502 creating a FIFO link. Also start testing embedded NUL behavior.
1503 Until the argument collection engine also shares references, the
1504 memory usage increases.
1505 Memory impact: noticeable penalty, due to longer life of argv
1506 changing O(n) to O(n^2) on boxed recursion.
1507 Speed impact: slight improvement, due less data copying.
1508 * ltdl/m4/gnulib-cache.m4: Import memmem and quote modules.
1509 * m4/m4module.h (m4_arg_scratch): New prototype.
1510 * m4/m4private.h (m4__push_symbol): Add parameter.
1511 (m4_arg_scratch): Add fast accessor.
1512 (struct m4): Add expansion_level member, taken...
1513 * m4/macro.c (expansion_level): ...from here. Adjust all users.
1514 (expand_argument): Minor cleanup.
1515 (expand_macro): Track scratch space per macro call.
1516 (m4_arg_scratch): New function.
1517 (m4_make_argv_ref): Call new function.
1518 (m4_push_arg): Push reference to $0.
1519 (m4_push_args): Rework separator usage, since separators will
1521 (process_macro): Allow embedded NUL.
1522 * m4/input.c (INPUT_INLINE_THRESHOLD): New define.
1523 (m4__push_symbol): Add parameter. Inline short strings, and save
1524 references through rescanning.
1525 * m4/symtab.c (m4_set_symbol_value_text): Weaken assertion.
1526 * modules/m4.c (errprint, index): Handle NUL transparently.
1527 (dumpdef, translit): Use scratch space, rather than expansion
1529 * modules/gnu.c (renamesyms, m4symbols): Likewise.
1530 * tests/others.at (nul character): New test.
1531 (iso8859): Quote absolute file name, remove XFAIL.
1532 * tests/iso8859.m4: Avoid raw NUL in output.
1533 * tests/null.m4: New file.
1534 * tests/null.out: Likewise.
1535 * tests/null.err: Likewise.
1536 * Makefile.am (OTHER_FILES): Distribute new files.
1537 * .gitattributes: Treat new files as text.
1539 2007-12-17 Eric Blake <ebb9@byu.net>
1541 Stage 8: extend life of references into argv.
1542 Add hooks to lengthen the lifetime of arguments reused in a macro
1543 expansion, rather than always discarding arguments at the end of
1544 expand_macro. Rework the expand_macro obstacks to handle longer
1545 lifetimes. For now, the hooks remain unused.
1546 Memory impact: slight penalty, due to larger structs.
1547 Speed impact: slight penalty, due to more bookkeeping.
1548 * m4/system_.h (obstack_regrow): Delete.
1549 * m4/m4private.h (struct m4_symbol_chain): Add level field.
1550 (m4__push_symbol): Adjust prototype.
1551 (m4__adjust_refcount): New prototype.
1552 (DEBUG_MACRO) [DEBUG]: New debug control.
1553 (struct m4__macro_arg_stacks): New structure.
1554 (struct m4): Add arg_stacks, stacks_count fields.
1555 * m4/m4module.h (m4_make_argv_ref): Add parameter.
1556 * m4/macro.c (argc_stack, argv_stack): Delete, replaced by
1557 context->arg_stacks.
1558 (m4_macro_expand_input) [DEBUG_MACRO]: Add debug hooks,
1559 conditional on M4_DEBUG_MACRO envvar.
1560 (collect_arguments): Adjust signature.
1561 (expand_macro): Rework obstack handling.
1562 (m4__adjust_refcount, arg_mark): New functions.
1563 (m4_make_argv_ref): Populate new field.
1564 (m4_push_arg, m4_push_args): Track inuse.
1565 (process_macro): One less cast.
1566 * m4/m4.c (m4_delete): Clean up arg_stacks.
1567 * m4/input.c (make_text_link): Use new field.
1568 (m4__push_symbol, file_clean): Update signature.
1569 (composite_read): Bump refcount when done with reference.
1570 (composite_clean): New function.
1571 (pop_input): Adjust caller.
1572 * m4/debug.c (m4_debug_message): Make assertion match comment.
1573 * modules/gnu.c (builtin, indir): Adjust callers.
1574 * tests/builtins.at (ifelse): New test.
1575 (exp): Move and rename...
1576 * tests/others.at (countdown): ...to this.
1577 * doc/m4.texinfo (Improved foreach): Fix tracing usage in
1580 2007-12-13 Eric Blake <ebb9@byu.net>
1583 * doc/m4.texinfo (Inhibiting Invocation): Missed one instance in
1588 2007-12-13 Paolo Bonzini <bonzini@gnu.org> (tiny change)
1590 * doc/m4.texinfo (Inhibiting Invocation): Fix quoting of a quoting
1592 Reported by Giovanni Toffetti.
1594 2007-12-11 Eric Blake <ebb9@byu.net>
1596 Stage 7: use chained input support in input parser.
1597 Allow the LIFO input engine to rescan a macro expansion composed
1598 of smaller chunks of FIFO data, rather than the old approach of a
1599 monolithic string. For now, all chunks are still copied.
1600 Memory impact: slight penalty, due to FIFO chain overhead.
1601 Speed impact: slight penalty, due to extra bookkeeping.
1602 * m4/m4private.h (m4__push_symbol): New prototype.
1603 (struct m4_symbol_chain): Add const-safety.
1604 * m4/symtab.c (m4_symbol_value_print): Simplify.
1605 (dump_symbol_CB): Update caller.
1606 * m4/input.c (struct m4_input_block): Alter u_c member, first
1607 introduced 2006-10-25, but unused until now.
1608 (composite_peek, composite_read, composite_unget)
1609 (composite_print, init_builtin_token): Rewrite accordingly.
1610 (m4_push_wrapup): No longer need trailing NUL.
1611 (m4__push_symbol, make_text_link): New functions.
1612 (m4_push_string_finish): Use them.
1613 * m4/macro.c (m4_push_arg, m4_push_args): Likewise.
1614 (expand_macro): Simplify logic of nesting_limit.
1615 * src/main.c (main): Likewise.
1616 * doc/m4.texinfo (Dumpdef): Augment test.
1618 2007-12-08 Eric Blake <ebb9@byu.net>
1620 Stage 6: convert builtins to push arg at a time.
1621 Add new methods to factor all builtins whose expansion includes an
1622 argument, making back-reference creation easier in future patches.
1623 Factor out length-limited printing to obstacks, and use -1 rather
1624 than 0 for unlimited length.
1625 Memory impact: none.
1626 Speed impact: slight improvement, due to better code sharing.
1627 * m4/m4module.h (m4_shipout_text): Rename...
1628 (m4_divert_text): ...to this, to avoid confusion with m4_shipout_*
1629 that does not worry about sync lines.
1630 (m4_shipout_string_trunc): New prototype.
1631 * m4/output.c (m4_shipout_text): Rename...
1632 (m4_divert_text): ...to this.
1633 (m4_shipout_string): Move guts...
1634 (m4_shipout_string_trunc): ...to this new function.
1635 * m4/macro.c (m4_push_arg, m4_push_args): New functions.
1636 (expand_token, process_macro): Update callers.
1637 * m4/input.c (string_print): Likewise.
1638 * modules/m4.c (ifdef, ifelse, shift, substr, translit, divert):
1640 * modules/gnu.c (patsubst): Likewise.
1641 (debuglen): Use SIZE_MAX for unlimited debug length.
1642 * src/main.c (main): Likewise.
1643 * m4/m4.c (m4_create): Default max_debug_length to SIZE_MAX, not
1646 2007-12-07 Eric Blake <ebb9@byu.net>
1648 Minor security fix: Quote output of mkstemp.
1649 * modules/m4.c (m4_make_temp): Produce quoted output.
1650 * doc/m4.texinfo (Mkstemp, Mkdtemp): Update the documentation and
1653 Stage 5: add notion of quote age.
1654 Cache the quoting rules that were in effect when a string was
1655 parsed, to avoid reparsing that string if no changequote or other
1656 quote age change took place in the meantime. A quote_age of 0 is
1657 always safe, but does not benefit from caching.
1658 Memory impact: slight improvement, due to smaller struct in input
1660 Speed impact: slight penalty, due to more bookkeeping.
1661 * m4/m4module.h (m4_get_symbol_value_quote_age): New prototype.
1662 (m4_set_symbol_value_text): Adjust prototype.
1663 (m4_has_syntax): Factor out the unsigned char cast.
1664 * m4/m4private.h (struct m4_syntax_table): Add syntax_age and
1666 (m4__quote_age, m4__safe_quotes): New accessor macros, no need for
1667 functions at this point.
1668 (struct m4_symbol_value, struct m4_macro_args): Add quote_age
1670 (m4_set_symbol_value_text): Adjust fast accessor.
1671 (m4_get_symbol_value_quote_age): New fast accessor.

1673 (m4_get_symbol_value_quote_age): New function.
1674 (m4_symbol_value_copy): Adjust callers.
1675 * m4/macro.c (expand_token): Add parameter, and track quote age.
1676 (expand_argument, collect_arguments): Track quote age.
1677 (m4_macro_expand_input, process_macro, m4_make_argv_ref)
1678 (m4_macro_expand_input): Update callers.
1679 (m4_arg_text, m4_arg_len, m4_arg_func): Abort on type mismatch.
1680 * m4/input.c: Comment cleanups.
1681 (struct m4_input_block): Reduce size.
1682 (m4__next_token): Report quote age.
1683 (m4_push_builtin, init_builtin_token): Update callers.

1686 * m4/syntax.c (m4_set_syntax): Initialize and update quote age.
1687 (m4_set_quotes, m4_set_comment): Detect no-op changes, and update
1689 (set_quote_age): New helper function.
1690 (check_is_single_quotes, check_is_single_comments): Adjust
1692 * src/freeze.c (reload_frozen_state): Likewise.
1693 * src/main.c (main): Likewise.
1694 * modules/m4.c (define, pushdef): No need to set macro text.
1695 * tests/builtins.at (changequote, defn): New tests.
1696 * examples/wrapfifo.m4: New file.
1697 * examples/wraplifo.m4: New file.
1698 * Makefile.am (dist_pkgdata_DATA): Distribute new examples.
1700 2007-12-04 Eric Blake <ebb9@byu.net>
1702 Fix builds with OpenBSD make.
1703 * Makefile.am (HELP2MAN): New macro.
1704 (dist_man_MANS, doc/m4.1): Fix rules for building m4.1 into
1706 * README: Update copyright.
1707 * HACKING: Mention help2man and makeinfo dependencies.
1709 2007-11-29 Eric Blake <ebb9@byu.net>
1711 Stage 4: route indir, builtin through ref; make argv opaque.
1712 Finish making struct opaque to all but the input engine, by
1713 reworking obstack usage in expand_macro to better support creation
1714 of a $@ reference. Canonicalize the empty argument, to allow
1715 pointer comparison optimizations.
1716 Memory impact: slight penalty, due to larger struct.
1717 Speed impact: slight improvement, due to fewer function calls.
1718 * m4/system_.h (obstack_regrow): Fix precedence.
1719 * m4/m4module.h (m4_arg_equal, m4_arg_empty, m4_make_argv_ref):
1721 (struct m4_macro_args): Move...
1722 * m4/m4private.h (struct m4_macro_args): ...here, making it opaque
1723 to modules. Add has_ref member.
1724 (bool_bitfield): New helper typedef.
1725 (struct m4_symbol_chain): Add flatten and len members.
1726 * m4/macro.c (empty_symbol): New placeholder, for optimizing
1727 comparison with empty string.
1728 (m4_macro_expand_input): Initialize it.
1729 (collect_arguments): Alter signature, and populate new fields.
1730 (trace_pre, trace_post): Remove redundant parameter.
1731 (expand_macro): Alter handling of obstacks.
1732 (m4_arg_symbol): Account for wrapped argv.
1733 (m4_arg_equal, m4_arg_empty, m4_make_argv_ref): New methods.
1734 (m4_arg_text, m4_arg_len, m4_arg_func): Use new methods.
1735 * modules/m4.c (ifelse, syscmd): Likewise.
1736 * modules/evalparse.c (m4_evaluate): Likewise.
1737 (undefine, popdef, m4_dump_symbols): Optimize.
1738 * modules/gnu.c (builtin, indir, esyscmd, debugfile): Use new
1740 (changesyntax, regexp): Optimize.
1741 * m4/output.c (diversion_storage): Use typedef.
1743 Stage 3b: cache length, rather than computing it, in modules.
1744 Use cached token length in builtins and output engine.
1745 Memory impact: none.
1746 Speed impact: noticeable improvement, due to fewer function calls.
1747 * m4/hash.c (m4_hash_remove): Avoid double free on remove
1749 * m4/output.c (m4_shipout_string): Change semantics of len param.
1750 (m4_shipout_int): Use cached length.
1751 * m4/input.c (m4_push_string_finish): Likewise.
1752 * modules/m4.h (m4_make_temp_func): Add parameter.
1753 * m4/macro.c (expand_token, m4_arg_len): Use cached length.

1756 (process_macro): All callers changed.
1757 * m4/utility.c (m4_dump_args): Likewise.
1758 * m4/symtab.c (m4_symbol_value_print): Likewise.
1759 * modules/gnu.c (__file__, __program__, builtin, indir)
1760 (m4symbols, mkdtemp, regexp_compile, regexp_substitute,
1761 renamesyms, patsubst, regexp, regexp_compile): Likewise.
1762 * modules/load.c (m4modules): Likewise.

1771 * tests/builtins.at (mkstemp): Likewise.
1772 * tests/others.at (iso8859): XFAIL this test, now that
1773 length-based handling allows NUL through part but not all of M4.
1775 2007-11-28 Eric Blake <ebb9@byu.net>
1777 Stage 3a: cache length, rather than computing it, in libm4.
1778 Cache the length of a token in the input engine and symbol table,
1779 to avoid repeating lots of strlen calls. Additionally, by using
1780 obstack length rather than strlen, the input engine can now
1781 support embedded NUL.
1782 Memory impact: slight penalty, due to larger struct.
1783 Speed impact: slight improvement, due to fewer function calls.
1784 * m4/m4module.h (struct m4_macro_args): Cache length.
1785 (m4_get_symbol_len, m4_get_symbol_value_len): New accessors.
1786 (m4_set_symbol_value_text): Change signature.

1794 (m4_push_wrapup): Track length of string input.
1795 (m4__next_token): Adjust all users of symbol text to track length,

1807 Adjust implementation.
1809 2007-11-27 Eric Blake <ebb9@byu.net>
1811 Stage 2: use accessors, not direct reference, into argv.
1812 Outside of macro.c, use accessor methods rather than direct access
1813 into the argv struct.
1814 Memory impact: none.
1815 Speed impact: slight penalty, due to increased function calls.
1816 * m4/m4private.h (m4_arg_argc): New fast accessor.
1817 * m4/m4module.h (m4_arg_argc, m4_arg_symbol, m4_is_arg_text)

1820 (m4_builtin_func, M4BUILTIN, M4BUILTIN_HANDLER, m4_dump_args)
1821 (m4_macro_call): Make argc unsigned.
1822 (M4ARG): Use new accessors.

1840 Stage 1: convert m4_symbol_value** into new object.
1841 Pass a variable-size wrapper structure instead of an array to
1842 builtins, so that subsequent optimizations in the structure need

1919 * m4/m4private.h (m4__symbol_type): Fix C89 compliance bug.
1921 2007-11-13 Eric Blake <ebb9@byu.net>
1923 Note: Patches titled Stage 0 through N form a series of patches
1924 which decreases the algorithmic complexity of tail recursion in
1925 macro expansions from O(n^2) to O(n) in both time and memory, then
1926 performs cleanups, such as handling of embedded NUL, made easier
1927 by the code refactoring.

2624 M4 was designed to have a small number of header files defining
2625 the interfaces to several source files each. Keeping this in

4680 SEGV in `renamesyms' resulting from using a new re_registers
4681 with an existing re_pattern_buffer:
4683 * modules/gnu.c (m4_pattern_buffer): Wrapper struct for associated
4684 pattern buffer and registers.
4685 (m4_regexp_search): New function to call re_regexp_search with
4686 correctly matched pattern buffer and register instantiations.
4687 (m4_regexp_compile): Return an m4_pattern_buffer. Adust all
4690 2006-07-04 Gary V. Vaughan <gary@gnu.org>
4692 * ltdl/m4/m4-getopt.m4 (M4_GETOPT): Update to take into account
4693 changes to gnulib getopt.m4 since last build.
4694 * Makefile.am (src_m4_SOURCES): Only compile shipped getopt module
4695 if the system getopt fails M4_GETOPT tests.

4710 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4712 * Makefile.am (src_m4_DEPENDENCIES): Make dependency explicit.
4713 (clean-local): Split into and depend upon...
4714 (clean-local-tests, clean-local-src): ...these two. The latter
4715 removes the libtool object directory below `src', to work around
4716 a buglet in Automake, failing to list it.
4717 (EXTRA_DIST): Distribute modules/perl.c.
4719 2006-06-19 Eric Blake <ebb9@byu.net>
4721 * Makefile.am ($(srcdir)/doc/m4.1): No need to list $(srcdir) in
4722 right side of dependency; VPATH does that.
4723 (stamp-vcl): Update to use libtool's algorithm.
4724 (EXTRA_DIST): Distribute stamp-vcl.
4725 Reported by Ralf Wildenhues.
4726 (TESTSUITE): Revert earlier change that used absolute path, as
4727 that broke 'make dist' in VPATH. Stick with $(srcdir) instead.
4728 (EXTRA_DIST): Revert earlier change of $(TESTSUITE).
4729 (TESTS_ENVIRONMENT) [USE_GMP]: Revert earlier addition, since
4730 atlocal takes care of it instead.
4731 (check-local, installcheck-local, clean-local): Inline absolute
4732 path to testsuite here, rather than relative path to testsuite
4735 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4737 * m4/m4private.h (DELETE): Cast away const here...

4752 Follow recommendations from autoconf manual for autotest.
4753 * Makefile.am (TESTSUITE): Factor the $(srcdir) out of uses, and
4754 turn it into an absolute path until autotest provides an option
4755 that allows us to avoid changing directories. Properly quote
4757 (TESTS_ENVIRONMENT) [USE_GMP]: Inform testsuite about GMP.
4758 (check-recursive): Delete unused target.
4759 ($(TESTSUITE)): Atomically update testsuite.
4760 (CD_TESTDIR): Simplify.

4786 * ltdl/m4/m4-gnulib.m4: Delete, no longer needed.
4788 Reduce compiler warnings. Inside GMP, mpq_t is an array type, so
4789 const mpq_t is not assignable from plain mpq_t. Avoid
4790 type-punning warnings caused trying to mix these types.
4791 * modules/mpeval.c (numb_ior, numb_eor, numb_and, numb_lshift),
4792 (numb_rshift, numb_divide, numb_modulo): Remove const qualifier.

4821 to avoid unnecessary rerunning of autotools for libltdl.
4823 2006-06-13 Eric Blake <ebb9@byu.net>
4827 2006-06-12 Eric Blake <ebb9@byu.net>
4829 * m4/output.c [HAVE_MKTEMP]: Gnulib provides mkstemp, so don't

4833 * configure.ac (AC_CHECK_FUNCS): Remove obsolete checks.

4867 * ChangeLog: Change encoding to UTF-8.
4869 Avoid compiler warnings.
4870 * m4/macro.c (trace_format): Don't mark this as a printf format,
4871 since we don't accept the same set of modifiers as printf. It
4872 would be nice if gcc let us specify a custom format archetype.
4873 * src/main.c (main): Cast away const.

4925 2005-12-05 Gary V. Vaughan <gary@gnu.org>
4927 * bootstrap (func_update_po): Synch with CVS GNU tar. wget 1.9.x
4928 and 1.10.x support --cache=off, so $WGETFLAGS are not necessary.

4931 2005-12-04 Gary V. Vaughan <gary@gnu.org>
4933 * bootstrap (func_update_po): Test and set $WGETFLAGS to disable
4934 http caching as -C is no longer supported by wget 1.10.x.
4935 Reported by Eric Blake <ebb9@byu.net>
4937 2005-10-20 Gary V. Vaughan <gary@gnu.org>
4939 * m4/module.c (caller_id): To match libtool-2.0 interface, changed
4941 (iface_id): ...an lt_dlinterface_id type.
4942 (m4__module_find): New abstraction for lt_dlhandle_fetch. Use
4943 throughout, instead of calling obsolete lt_dlhandle_find directly.
4944 (m4__module_next): Use multiloader-safe lt_dlhandle_iterate. Use
4945 throughout, instead of calling obsolete lt_dlhandle_next.

4959 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4961 * ltdl/m4/m4-gnulib.m4: Update FSF contact address. Somehow this
4962 file escaped the address updates on 2005-05-01.
4964 2005-07-07 Gary V. Vaughan <gary@gnu.org>
4966 * bootstrap: Allow user overriding of gnulib-tool location, and
4967 correctly determine module source directories whether gnulib-tool
4968 is given as a relative or absolute path, or is found by searching

4994 (erenamesyms, renamesyms): ...builtins that use these to implement
4995 macro renaming by regular expression.
4996 * doc/m4.texinfo (Erenamesyms and Renamesyms): Document them.
4997 * tests/generate.awk: Allow some forbidden `m4_' prefixed symbols
4998 to stop the new generated tests from choking.
5000 2005-05-07 Gary V. Vaughan <gary@gnu.org>
5002 Since most of the build is handled from a single Makefile.am now,
5003 we can teach make about the dependencies between the m4 binary and
5004 the preopened modules it is built against:
5006 * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
5008 * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
5009 of the preopened modules have changed.
5011 2005-05-07 Gary V. Vaughan <gary@gnu.org>

5014 have a native implementation.
5016 2005-05-06 Gary V. Vaughan <gary@gnu.org>

5022 --disable-assert configure time option for NDEBUG setting.
5024 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.

5040 Forward port of a patch that allowed m4-1.4.2 to compile on
5043 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
5045 * src/m4.h: And include them as appropriate.
5046 * src/main.c, src/stackovf.h: Don't include signal.h literally;
5047 m4.h will include the correct file.
5049 2005-05-04 Gary V. Vaughan <gary@gnu.org>
5051 * m4/m4private.h: Make errno visible for the sources patched
5054 2005-05-04 Paul Eggert <eggert@twinsun.com>
5056 * src/main.c (print_program_name_CB): Preserve errno, since
5057 M4ERROR relies on this.
5058 * modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
5059 * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
5060 * m4/path.c (m4_path_search): Don't let "free" trash errno when
5063 * m4/output.c (m4_insert_file): Don't assume errno has a valid
5064 value simply because fread returns zero. This fixes a
5065 portability bug reported by Marion Hakanson in
5066 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.

5080 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
5081 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
5082 and libtoolize does a better job of ltdl importing now too, so
5083 take advantage of that while updating the tree:
5085 * acm4, config: Moved from here...
5086 * ltdl/m4, ltdl/config: ...to here.
5087 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,

5090 compensate for relative path differences.
5091 * commit: Adjust relative paths.
5092 * configure.ac: Adjust relative paths.
5093 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
5095 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
5096 the meanwhile, CVS HEAD libtool is needed.
5097 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
5098 stricly new enough, we also need a patch.
5099 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
5100 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
5101 (gl_MODULES): Don't list getopt and version-etc, as they don't
5103 * bootstrap: After running gnulib-tool to import the listed
5104 modules, fetch getopt and version-etc into src manually.
5105 (ltdldir): Change to ltdl.
5106 * src/main.c: Adjust for changes in version-etc API.
5107 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
5108 but works when the getopt module isn't to be included in the lib.
5109 * README: Add note about patching autoconf and automake to

5119 mkstemp rather than mktemp.

5171 matching macro names before each definition. Also, move all the
5172 function definitions to the end of the file so that any
5173 invocations in the rest of the file pick up the fast macro
5175 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)
5176 (m4_set_debug_file, m4_set_trace_messages)
5177 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
5178 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
5179 (m4_set_max_debug_arg_length_opt): New fast macro versions of the
5180 option setter functions.
5182 2004-09-23 Gary V. Vaughan <gary@gnu.org>
5184 * po/POTFILES.in: Reflect move of gnulib files from gnulib/m4
5187 2004-09-23 Gary V. Vaughan <gary@gnu.org>
5189 * src/main.c: Include gnulib files from the correct directory.
5191 * gnulib/*: Don't store any of the gnulib files in arch, as they
5192 generate spurious changes.
5193 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
5194 gnulib macros now share our macro directory.
5195 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
5196 * bootstrap: Call gnulib-tool to import from the gnulib tree.
5197 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
5198 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
5199 the gettext macros from autopoint that overwrite the gnulib-tool
5200 imported versions. Import sources and Makefile.am into the `gnu'
5201 directory. Changed all callers.
5202 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
5203 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
5204 for imported modules.
5205 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
5206 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
5207 hardcoding the gnulib macros they wrap.
5209 2004-07-15 Gary V. Vaughan <gary@gnu.org>
5211 Latest CVS libtool can preload modules in libraries, including
5212 its own module loaders! Tweak m4 so that it doesn't try to treat
5213 libltdl's module loaders as m4 modules when freezing and on exit:
5215 * gnulib/acm4/*.m4: Don't store these files in arch since they
5216 generate spurious changes.
5217 * bootstrap: Simplify initial libtoolize call, since CVS
5218 libtoolize is smarter these days.
5219 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
5221 * m4/module.h (m4__module_exit): Missing declaration.
5222 * m4/m4private.h (m4__module_next): New function declaration.
5223 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
5224 encapsulation. Changed all callers.
5225 (m4__module_interface): New function to verify m4 loadable module
5227 (m4__module_init): Register the interface validator.
5228 (m4__module_exit): Only close my own modules.
5229 * modules/m4.c (unistd.h): Provide missing declaration.
5230 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
5231 (m4_expand_ranges): More missing declarations.
5232 * modules/modtest.c (export_test): Ditto.
5233 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
5234 * src/main.c (main): Bump copyright year.
5235 * tests/modules.at: Fix sed syntax error.
5238 2004-06-17 Gary V. Vaughan <gary@gnu.org>
5240 Tweaking to enable compilation with latest CVS libtool and
5241 libltdl. We can't just dump the library files directly into the
5242 m4 directory anymore now that libltdl is built from pieces itself:
5244 * bootstrap: Rewritten to use latest libtoolize sanely, and to
5245 set up libltdl subdirectory.
5246 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
5247 gnulib subdirectory's config.
5248 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
5249 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
5251 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
5252 configure.ac, so use AC_WITH_LTDL instead.
5253 * Makefile.am (SUBDIRS): Add libltdl.
5254 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
5256 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
5257 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
5258 (libm4_la_LIBADD): Add LIBLTDL.
5259 * m4/ltdl.c, m4/ltdl.h: Removed.
5260 * m4/m4module.h: Include canonical ltdl.h.
5263 2004-06-14 Gary V. Vaughan <gary@gnu.org>
5265 * gnulib/import: Now updates makefile fragments, and configure.ac.
5266 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
5267 * gnulib/m4/Makefile.am: include it.
5268 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
5269 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
5270 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
5271 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
5272 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
5273 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,
5274 gnulib/acm4/lib-ld.m4, gnulib/acm4/lib-prefix.m4,
5275 gnulib/acm4/error.m4, gnulib/acm4/po.m4, gnulib/acm4/regex.m4,
5276 gnulib/acm4/stdbool.m4, gnulib/acm4/stdint_h.m4,
5277 gnulib/acm4/uintmax_t.m4, gnulib/acm4/ulonglong.m4,
5278 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
5279 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
5280 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
5282 * gnulib/m4/getopt_int.h: New source file from latest gnulib
5284 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
5285 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,
5286 gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
5287 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
5288 Updated source files from latest gnulib.
5290 2004-02-29 Gary V. Vaughan <gary@gnu.org>
5292 * config/mailnotify: New file for mailing commit notifications,
5293 imported from cvs-utils.
5294 * commit: Updated from cvs-utils and tweaked for m4.
5296 2003-12-01 Gary V. Vaughan <gary@gnu.org>
5298 * config/mkstamp: Updated from CVS libtool.
5299 * configure.ac: Generate a gnu coding standards compliant version
5300 number, and use it for the banner.
5301 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
5302 mhen the TIMESTAMP changes in ChangeLog, but the file modification
5303 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
5304 contain the previous version number.
5305 * src/main.c: Make --version output conform to the GNU standard.
5307 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
5308 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
5309 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
5310 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
5311 time_la_SOURCES): ...so that these are defaulted correctly, and
5312 can be removed from this file.
5313 (AM_LDFLAGS): Add -module...
5314 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
5315 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
5316 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
5317 the individual settings can be removed.
5318 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
5319 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
5320 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
5321 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
5322 time_la_LIBADD): ...so that these are picked up as a deplib of
5323 libm4 and don't need to be set explicitly.
5325 2003-11-18 Gary V. Vaughan <gary@gnu.org>
5327 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
5328 from the standard build. It is too fragile.
5330 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
5331 CVS libtool after merging m4 changes across to libtool.
5333 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
5334 * m4/path.c (search_path_add): Ditto.
5336 2003-11-13 Gary V. Vaughan <gary@gnu.org>
5338 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
5339 libtool tags we don't use in configure. This reduces the size
5340 of the script from over 1Mb to under 700Kb.
5342 2003-11-13 Gary V. Vaughan <gary@gnu.org>
5344 The import script was not written properly, and the last gnulib
5345 import was incomplete. Fixed that problem, and reimport our
5346 gnulib dependencies, which picks up the address calculation
5347 overflow checks described by Paul below. Also tweak the clients
5348 of the gnulib xalloc module not to use deprecated macros:
5350 * gnulib/import: Recurse through module dependencies rather than
5351 naively descending only one level.
5352 * configure.ac: Add calls to gnulib's strnlen and extension module
5354 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
5356 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
5357 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
5358 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
5359 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
5361 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
5362 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
5363 place of `xcalloc (1, S)'.
5364 * m4/m4.c (m4_create): Likewise.
5365 * m4/m4private.h (m4_symbol_value_create): Likewise.
5366 * m4/symtab.c (symtab_fetch): Likewise.
5367 * m4/syntax.c (m4_syntax_create): Likewise.
5368 * src/freeze.c (reload_frozen_state): Likewise.
5369 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
5371 * m4/symtab.c (m4_symtab_create): Likewise.
5373 2003-11-13 Gary V. Vaughan <gary@gnu.org>
5375 * tests/module.at: Comment typo.
5377 2003-10-10 Gary V. Vaughan <gary@gnu.org>
5379 * tests/modules.at (modules: importing): Apply some lateral
5380 thinking, and use AT_CHECK to compare the output of a sed pass
5381 over stderr against the canonical strerror string.
5383 * tests/modules.at (modules: importing): Edit the generated stderr
5384 output to canonicalize strerror output, before a comparison.
5386 2003-10-10 Gary V. Vaughan <gary@gnu.org>
5388 Tru64UNIX perl is sloppy with namespace pollution. This patch is
5389 careful not to trip over the mess:
5391 * modules/perl.c: Some builds of perl install headers that contain
5392 `#define try __builtin_try'. Be sure to undefine that macro
5393 before `m4/hash.h' gets included, which uses the `try' symbol.
5394 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
5395 `false' before including `stdbool.h'.
5396 (DELETE): This symbol is not in m4's namespace, and is in any
5397 case only used internally...
5398 * m4/m4private.h (DELETE): ...so move it to here.
5399 Reported by Martin MOKREJS <mmokrejs@natur.cuni.cz>
5401 2003-10-08 Paul Eggert <eggert@twinsun.com>
5403 Don't use XMALLOC and XCALLOC. Once we install the
5404 corresponding patch into gnulib, this will fix some
5405 address-calculation overflow bugs on hosts where calloc (A, B)
5406 returns garbage when A*B overflows.
5408 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
5409 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
5410 xmalloc, XCALLOC with xcalloc.
5411 * m4/m4.c (m4_create): Likewise.
5412 * m4/m4private.h (m4_symbol_value_create): Likewise.
5413 * m4/output.c (m4_output_init): Likewise.
5414 * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise.
5415 * m4/syntax.c (remove_syntax_attribute): Likewise.
5416 * src/freeze.c (reload_frozen_state): Likewise.
5417 * src/main.c (main): Likewise.
5419 2003-10-07 Gary V. Vaughan <gary@gnu.org>
5421 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
5422 gnulib/acm4 directories for aclocal m4 macros.
5423 * gnulib/Makefile.am (EXTRA_DIST): Removed.
5424 (MAINTAINERCLEANFILES): Add Makefile.in.
5425 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
5427 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
5428 * gnulib/import: New file. Temporary script for updating gnulib
5429 imported files, until gnulib-tool is working.
5430 * gnulib/config/codeset.m4, gnulib/config/error.m4,

5468 gnulib/acm4/xstrndup.m4: Reimported from CVS gnulib with
5469 gnulib/import script.
5470 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/error.c,

5475 gnulib/m4/xalloc.h, gnulib/m4/xmalloc.c: Updated from CVS
5476 gnulib with gnulib/import script.
5477 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
5478 guards ready for gnulib-tool to autoupdate on import.

5480 config/m4-gettext.m4, config/m4-obstack.m4, config/m4-regex.m4,

5504 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.

5508 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
5509 Gary V. Vaughan <gary@gnu.org>
5511 * bootstrap: Separate options.
5512 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
5513 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
5515 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
5516 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
5517 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
5518 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
5519 $(LTLIBINTL) for gettext support on cygwin.
5520 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
5521 have $(LTLIBINTL) from the preloaded module la files.
5522 * README: Remove the warning about using --disable-nls on Windows
5525 2003-09-15 Gary V. Vaughan <gary@gnu.org>
5527 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
5528 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
5531 2003-09-12 Gary V. Vaughan <gary@gnu.org>
5533 * doc/STYLE: Document the gnulib header naming conventions, and
5535 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
5536 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,

5546 2003-09-12 Gary V. Vaughan <gary@gnu.org>
5548 Replace the getopt code with CVS gnulib getopt. The source files
5549 detect whether they are in a glibc environment and preprocess away
5550 all of the code if there is a system getopt, so we can compile
5551 them into the m4 executable unconditionally:
5553 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
5554 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
5555 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
5557 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
5559 * src/Makefile.am: Adjust.
5560 * src/main.c: Always include our shipped getopt.h.
5561 * po/POTFILES.in: Use new location of getopt.c.
5563 2003-09-12 Gary V. Vaughan <gary@gnu.org>
5565 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
5566 * config/Makefile.am: Removed. Automake 1.8 distributes the files
5567 in this directory automatically.
5568 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
5570 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
5572 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
5574 * modules/Makefile.am (pkglibexecdir): Set it here.
5575 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
5577 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
5578 Import regex module from CVS gnulib.
5579 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
5580 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
5581 do extra substitutions for Makefile.
5582 * configure.ac: Use it.
5583 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
5584 from regex_.h if necessary.
5585 * m4/system_.h: Include the correct version of regex.h.
5586 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
5588 * po/POTFILES.in: Use new location of regex.c.
5590 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
5591 realloc.c: automake distributes these files already.
5593 2003-09-12 Gary V. Vaughan <gary@gnu.org>
5595 Replace the xstrzdup code by importing the xstrndup module from
5596 CVS gnulib, along with its dependencies: strndup and strnlen:
5598 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
5599 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
5601 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
5602 gnulib/config/strndup.m4: Ditto wrt strndup.
5603 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
5605 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
5606 However, contrary to gnulib, we install xstrndup.h.
5607 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
5608 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
5609 is an artifact of the old m4 portability layer.
5610 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
5611 * m4/system_.h: Include xstrndup.h.
5612 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
5614 2003-09-11 Gary V. Vaughan <gary@gnu.org>
5616 Reimport the latest xalloc module from CVS gnulib, and adjust the
5617 m4 sources to take advantage of xalloc xfree. Also create a new
5618 macro DELETE with the same semantics as the old m4 XFREE macro,
5619 and carefully tweak callers:
5621 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
5623 * m4/utility.c (xfree): Removed. This function is now supplied by
5625 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
5626 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
5627 * m4/symtab.c (m4_symtab_create): Ditto.
5628 * m4/system_.h: Removed XFREE redefine.
5629 (DELETE): New macro with same functionality as the original m4
5630 XFREE macro, but based on xalloc.h now. Changed all callers.
5631 * src/main.c (main): Use XMALLOC macro.
5632 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
5634 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
5636 2003-09-10 Gary V. Vaughan <gary@gnu.org>
5638 Import the xalloc module from CVS gnulib, along with its
5639 dependencies: exitfail, malloc and realloc. We had different
5640 semantics for our XFREE and a function xfree() not supplied by
5641 gnulib, so also a bit of work to keep everything running
5644 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
5645 (gl_XALLOC): Use gnulib equivalents.
5646 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
5647 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
5648 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
5649 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
5651 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
5652 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
5653 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
5655 (pkgincdir): Removed. Use pkgincludedir instead.
5656 * m4/m4private.h (XFREE): xfree already checks for NULL.
5657 * m4/system_.h: Use xalloc module, and remove macros already
5658 supplied by xalloc.h.
5659 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
5660 moved the old definition from m4/xmalloc.c to here for now.
5662 2003-09-09 Gary V. Vaughan <gary@gnu.org>
5664 Import the error and progname modules from CVS gnulib. Our old
5665 error.c subsumed the functionality of both, so a little adjustment
5666 was required to accomodate the split in sources. Also added more
5667 wrapper macros to choose between a system installed error.h or our
5668 shipped gnulib error module:
5670 * m4/error.c, m4/error.h: Removed.
5671 * m4/Makefile.am: Adjust.
5672 (pkgincdir): Removed. Use pkgincludedir instead.
5673 * m4/module.h, src/main.c: Don't include `m4/error.h'.
5674 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
5676 * gnulib/m4/progname.c: Imported from CVS gnulib.
5677 * gnulib/m4/progname.h: Ditto.
5678 * src/main.c: Adjust to use progname module.
5679 * gnulib/m4/error.c: Imported from CVS gnulib.
5680 * gnulib/m4/error_.h: Ditto.
5681 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
5682 if appropriate, and link a local error.h if the system version is
5684 (libgnu_la_SOURCES) Add progname module sources.
5685 * gnulib/config/error.m4: Imported from CVS gnulib.
5686 * gnulib/config/strerror_r.m4: Ditto.
5687 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
5688 to have ERROR_H for Makefile substitutions and tell system.h
5689 whether the system error.h should be used, or a locally installed
5691 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
5693 2003-09-09 Gary V. Vaughan <gary@gnu.org>
5695 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
5696 s/gettext_.h/gettext.h/.
5698 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
5699 automake have been fixed.
5701 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
5702 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
5703 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
5704 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
5706 2003-09-09 Gary V. Vaughan <gary@gnu.org>
5708 The gnulib obstack module requires the gnulib gettext module for
5709 systems that do not have GNU gettext installed. Because we use
5710 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
5711 that directory incase it clashes with the system gettext.h. This
5712 delta uses gettext_.h and extra rules in the Makefile to make a
5713 link to gettext.h when needed:
5715 * Makefile.am (auxdir): Removed. No longer used.
5716 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
5717 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
5719 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
5720 Makefile based build.
5721 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
5722 of the macros are kept.
5723 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
5724 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
5725 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
5726 distributes these automatically.
5727 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
5728 warning from automake-1.7a.
5729 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
5730 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
5732 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
5733 wrt. m4_FUNC_OBSTACK.
5734 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
5735 wrt. m4_sys_STACKOVF.
5736 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
5737 wrt. _m4_LIB_GMP, m4_LIB_GMP.
5738 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
5739 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
5741 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
5742 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
5743 gettext.h link on deficient systems.
5744 (pkginc_HEADERS): Mention $(GETTEXT_H).
5745 (EXTRA_HEADERS): Mention gettext.h.
5746 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
5747 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
5748 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
5749 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
5750 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
5751 gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
5752 gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
5753 gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
5754 gnulib/config/po.m4, gnulib/config/progtest.m4,
5755 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
5756 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
5758 2003-09-05 Gary V. Vaughan <gary@gnu.org>
5760 We can't mirror the gnulib directory structure here, since we need
5761 to be able to eg. `#include <m4/obstack.h>' from our source files,
5762 which is much easier if the local obstack.h is created in a
5763 directory named m4. Rather than trying to symlink everything into
5764 the m4 directory, now we build a libtool convenience library from
5765 the sources we get from gnulib and link that with libm4.la:
5767 * gnulib/config/extensions.m4: Imported from CVS gnulib.
5768 * gnulib/config/unlocked-io.m4: Ditto.
5769 * gnulib/m4/unlocked-io.h: Ditto.
5770 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
5771 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
5772 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
5773 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
5774 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
5775 * m4/Makefile.am: Adjust.
5776 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
5777 macros we redistribute.
5778 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
5779 library among others.
5780 (GNULIB_SRCS, GNULIB_MACROS): Removed.
5781 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
5782 * config/m4-obstack.m4: Adjust.
5783 * po/POTFILES.in: Adjust.
5784 * configure.ac: Reformatting. Call newly imported gnulib macros.
5785 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
5786 bogus calls of `#include "m4.h"'.
5787 * Makefile.am: INCLUDES has been deprecated in favour of
5789 * m4/Makefile.am: Ditto.
5790 * modules/Makefile.am: Ditto.
5791 * src/Makefile.am: Ditto.
5793 2003-09-05 Gary V. Vaughan <gary@gnu.org>
5795 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
5797 2003-09-04 Gary V. Vaughan <gary@gnu.org>
5799 Migrate the obstack support into the gnulib directories for easy
5800 synchronisation with upstream files in gnulib:
5802 * config/gnu-obstack.m4: Moved from here...
5803 * config/m4-obstack.m4: ...to here.
5804 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
5805 * m4/obstack.c, m4/obstack_.h: Moved from here...
5806 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
5807 * po/POTFILES.in: Adjust.
5808 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
5809 * m4/Makefile.am: Add a whole new section to link the obstack
5810 sources from the gnulib tree if necessary.
5811 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
5813 * config/m4-obstack.m4: Rewrite as a wrapper for
5814 gnulib/m4/obstack.m4.
5816 2003-09-04 Gary V. Vaughan <gary@gnu.org>
5818 GNU M4 currently builds with a number of files adapted from
5819 upstream sources. Recently the gnulib project on savannah.gnu.org
5820 has pulled together a great many of these externally maintained
5821 files. This delta is the beginnings of isolating those files
5822 maintained in gnulib to make it easy to synchronise M4 with the
5823 upstream files prior to releases.
5825 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
5827 (SUBDIRS): Added new gnulib subdirectory.
5828 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
5829 * config/stdbool.m4: Moved from here...
5830 * gnulib/m4/stdbool.m4: ...to here.
5831 * m4/stdbool_.h: Moved from here...
5832 * gnulib/lib/stdbool_.h: ...to here.
5833 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
5835 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
5836 code to work with new stdbool_.h location.
5837 (gnulib_srcdir): New.
5839 2003-09-04 Gary V. Vaughan <gary@gnu.org>
5841 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
5842 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
5844 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
5845 (EXTRA_DIST): Use it.
5847 * bootstrap: CVS autoreconf leaves file droppings. Remove
5848 aclocal.m4t incase autoreconf doesn't.
5850 2003-08-29 Gary V. Vaughan <gary@gnu.org>
5852 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
5853 the other gnulib imports, renamed to m4/obstack_.h.
5854 * m4/obstack.c: Updated from CVS gnulib.
5855 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
5856 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
5857 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
5858 about vpath already, and $top_srcdir upsets CVS Automake, so the
5859 $top_srcdir reference was removed.
5861 * m4/system-h.in: For consistency with the gnulib imports, renamed
5863 * m4/Makefile (EXTRA_HEADERS): Adjust.
5864 * configure.ac (AC_CONFIG_FILES): Adjust.
5866 * m4/stdbool_.h: New file from gnulib for systems without their
5868 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
5869 * config/stdbool.m4: New file. Macros from gnulib for same.
5870 * configure.ac: Use it.
5872 2003-08-27 Gary V. Vaughan <gary@gnu.org>
5874 * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'`

5921 * src/main.c: Ditto.
5922 * src/stackovf.c: Ditto.
5924 * config/gmp.m4 (M4_AC_LIB_GMP): Use AC_INCLUDES_DEFAULT:
5925 ac_default_headers is an autoconf internal variable.
5926 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
5927 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
5929 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
5930 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
5933 2003-08-15 Gary V. Vaughan <gary@gnu.org>
5935 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
5937 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
5938 possible or faking one with a typedef. Changed all callers.
5940 2003-08-15 Gary V. Vaughan <gary@gnu.org>
5942 Still cleaning up the users' module API, by taking out the stuff
5943 that isn't used by any existing modules, and moving specialised
5944 functions out of libm4 and into the module they are used by.
5946 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
5947 * m4/utility.c (m4_skip_space): ...to here the home of its only
5948 use, made static and renamed to `skip_space'. Changed all
5950 * m4/m4module.h (m4_expand_ranges): Removed prototype.
5951 * m4/utility.c (m4_expand_ranges): Moved definition from here...
5952 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
5954 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
5956 * modules/gnu.c (builtin_syntax): Import and use in this
5957 builtin implementation.
5958 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
5960 * m4/macro.c (trace_flush): Except here where the macro is now
5962 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
5963 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
5965 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
5966 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
5968 2003-08-14 Gary V. Vaughan <gary@gnu.org>
5970 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
5971 compiler based AC_CHECK_HEADER that was introduced in
5973 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
5974 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
5975 * configure.ac: Use renamed M4_AC_LIB_GMP.
5977 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
5978 macro that requires arguments! This stops the shell's bad
5979 substitution error at configure time.
5981 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
5982 variables to the testsuite shell. Set the value of USE_GMP so
5983 that the gmp test will run!
5984 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
5986 2003-08-11 Gary V. Vaughan <gary@gnu.org>
5988 Libltdl already has an excellent mechanism for accessing C symbols
5989 in modules. Lets use that! Remove all the exporting cruft and
5990 just use lt_dlsym in conjunction with a few conventions to
5991 simplify module writers' jobs. Also removed the table address
5992 caching code and otherwise simplified the module loader quite a
5993 bit. To access exported symbols in other modules, first the
5994 exporting module must name the symbols <modname>_LTX_<symname>,
5995 and the importing module must define a function type called
5996 <symname>_func. The importer then adds
5997 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
5998 that wishes to call out to the exported functions. Care must be
5999 taken that <symname> is non-NULL in the importing module incase
6000 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
6001 definition was in the importers source. Study
6002 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
6003 m4_module_import will attempt to automatically load a module
6004 required for symbol access if it is not loaded already.
6006 * TODO: Removed the items fixed in this delta.
6007 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
6009 * m4/ltdl.h (lt_dlhandle_find): Declare it.
6010 * m4/module.c (m4_module_unload): Use it.
6011 * src/freeze.c (reload_frozen_state): Ditto.
6012 * m4/m4module.h (m4_export): Deleted. Removed all references.
6013 (M4_MODULE_IMPORT): New user convenience macro for importing
6014 arbitrary symbols from other modules.
6015 * m4/module.c (m4_module_import): New function to service
6016 M4_MODULE_IMPORT macro.
6017 (module_data): Removed. Looking up the tables on demand with
6018 lt_dlsym, rather than caching their addresses here simplifies the
6020 (m4_get_module_builtin_table, m4_get_module_macro_table):
6021 Removed. Changed all callers.
6022 (set_module_macro_table, set_module_builtin_table): Renamed to
6023 install_macro_table and install_builtin_table respectively, and
6024 simplified now that the cache is no more.
6025 * modules/gnu.c (builtin_symbols): Use this new mechanism to
6026 import m4_dump_symbols from the m4 module.
6027 (builtin_esyscmd): Likewise for m4_set_sysval and
6029 * modules/m4.c (m4_export_table): Removed. Functions are
6030 addressed with the new mechanism which doesn't need this.
6031 (m4_set_sysval): New exported accessor function to prevent
6032 problems with variable access on inferior architectures.
6033 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
6034 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
6035 that we can have some type safety.
6036 * modules/modtest.c (export_test): C level exported function for
6037 testing the new import mechanism.
6038 * modules/import.c: New file for the import end of the test.
6039 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
6040 * tests/modules.at: New test cases for intermodule symbol
6043 2003-08-07 Gary V. Vaughan <gary@gnu.org>
6045 * m4/m4module.c (m4_string): Moved from here...
6046 * m4/m4private.c (m4_string): ...to here.
6048 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
6050 2003-07-29 Gary V. Vaughan <gary@gnu.org>
6052 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
6053 already available to module writers through
6054 m4_{get,set}_nesting_limit_opt(), so moved from here...
6055 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
6056 (m4_create): Use it.
6058 2003-07-28 Gary V. Vaughan <gary@gnu.org>
6060 Aside from auditing path.c for m4module.h api obfuscation, this
6061 delta introduces the concept of private struct members in opaque
6062 data types to GNU m4: See the STYLE file for details.
6064 * TODO: Remind ourselves that a rewrite of path.c is needed.
6065 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
6067 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
6068 here and renamed. These type definitions are for internal api use
6069 only. Changed all callers.
6070 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
6072 * m4/path.c (search_path_env_init, search_path_add): ...to here
6073 and renamed. These calls were never used outside this file.
6074 Changed all callers.
6075 (dirpath): Moved functionality of this static declaration...
6076 * m4/m4private.h (struct m4): ...to this new internal only
6077 search_path field. Changed all callers.
6078 (m4__get_search_path): Added new internal api accessor.
6079 * m4/path.c (m4_search_path_info_new): Removed. Not used.
6080 (m4_include_init): Removed...
6081 * m4/m4.c (m4_create): ...because the new m4 field is now
6083 (m4_delete): Recycle search_path memory.
6084 * src/main.c (main): Don't call m4_include_init now that it's
6086 * doc/STYLE: Document convention for private fields in opaque
6089 2003-07-24 Gary V. Vaughan <gary@gnu.org>
6091 Sometimes exporting the address of a symbol from a module isn't
6092 enough for other modules to call that symbol correctly. If
6093 custom data types are used for function parameters, they need to
6094 be known to the caller. This change introduces the concept of
6095 $(prefix)/include/modules/$(modulename).h to declare those
6096 structures. Also we move m4_dump_symbols from libm4 to the m4
6097 module to show this concept in action.
6099 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
6100 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
6101 exporting data structures from modules/m4.c.
6102 * modules/m4.c, modules/gnu.c: Include it.
6103 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
6104 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
6106 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
6108 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
6109 ...to here, with slight renaming.
6110 (m4_export_table): Prototype and add m4_dump_symbols.
6111 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
6112 definition of m4_dump_symbols.
6113 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
6114 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
6116 2003-07-24 Gary V. Vaughan <gary@gnu.org>
6118 Create an export table in modules/m4.c in readiness for beefing up
6119 the module loader to track module exports and imports.
6121 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
6122 * m4/debug.c (m4_debug_flush_files): Moved...
6123 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
6124 * modules/gnu.c (builtin_esysval): Use it.
6125 * m4/m4module.h (m4_export): New type for declaring module symbols
6127 * modules/m4.c (m4_export_table): List symbols exported from this
6128 module for use by other modules.
6130 2003-07-24 Gary V. Vaughan <gary@gnu.org>
6132 An experiment: There is loads of code in libm4 which should be in
6133 the m4 module, but is also used by another module. Just because
6134 some linkers won't cope with calls across dynamic runtime loaded
6135 objects I initially left the code in libm4. It will tidy the
6136 module api immensely if this code moves to the right place, I just
6137 need to remember to invent a suitable calling mechanism at some
6138 point. For now, only modules that are statically linked and
6139 preloaded will get this treatment, so the only platforms that will
6140 break are those that require all symbols to be resolved at link
6143 * TODO: Reminder that what I am doing could reduce portability
6144 unless I do something more robust later.
6145 * m4/m4module.h (m4_sysval): No longer exported from libm4.
6146 * m4/utility.c (m4_sysval): No longer declared in libm4.
6147 * modules/Makefile.am: Reformatting.
6148 * modules/m4.c (m4_sysval): Declare it at place of use.
6149 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
6151 2003-07-23 Gary V. Vaughan <gary@gnu.org>
6153 * m4/m4module.h: Reformatting and rearranging lines a bit.
6154 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
6156 (m4_call_macro, m4_expand_input): Renamed...
6157 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
6159 (m4_expansion_level, m4_process_macro): Moved...
6160 * m4/macro.c (expansion_level, process_macro): ...to here, and
6163 * m4/m4module.h (program_name): Not used by modules at all, so
6165 * src/main.c (program_name): ...to here.
6166 (print_program_name): Renamed...
6167 (print_program_name_CB): ...to conform to the STYLE guide.
6169 2003-07-23 Gary V. Vaughan <gary@gnu.org>
6171 More refactoring of the m4module.h API. Replace #defines with an
6172 enum, and move non-public functions out of the public API.
6174 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
6176 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
6177 * m4/debug.c (m4_debug, trace): Moved...
6178 * m4/m4private.h (struct m4): ...to fields of this struct.
6179 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
6181 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
6182 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
6183 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
6184 * m4/m4module.h (m4_context_field_table): Add entries for new
6185 debug_file and trace_messages fields.
6186 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
6187 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
6188 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
6189 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
6190 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
6191 (m4_is_debug_bit): New macro to simplfy checks against the debug
6193 (m4_trace_format, m4_trace_header, m4_trace_flush)
6194 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
6196 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
6197 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
6198 * m4/macro.c (trace_format, trace_header, trace_flush)
6199 (trace_prepre, trace_pre, trace_post): ...to these newly static
6200 functions, since they are only ever used from this file. Changed
6203 2003-07-17 Gary V. Vaughan <gary@gnu.org>
6205 Change the macros for checking syntax so that matching against
6206 multiple possible syntax classes can be done with a single
6207 comparison some of the time. The various classes are now bits of
6208 an int that can be checked with bitwise logic operators.
6210 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
6211 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
6212 (M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)
6213 (M4_SYNTAX_ASSIGN, M4_SYNTAX_ALPHA, M4_SYNTAX_NUM)
6214 (M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)
6215 (M4_SYNTAX_ECOMM): Replaced #defines with an enum.
6216 (M4_SYNTAX_ALNUM): Removed. Changed all callers.
6217 (M4_IS_IGNORE, M4_IS_OTHER, M4_IS_SPACE, M4_IS_OPEN, M4_IS_CLOSE)
6218 (M4_IS_COMMA, M4_IS_DOLLAR, M4_IS_ACTIVE, M4_IS_ESCAPE)
6219 (M4_IS_ASSIGN, M4_IS_ALPHA, M4_IS_NUM, M4_IS_LQUOTE, M4_IS_RQUOTE)
6220 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
6221 Replace all calls with invocations of these...
6222 (m4_is_syntax, m4_has_syntax): ...New macros.
6223 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
6224 is no longer required with new macros. Changed all callers.
6226 2003-07-15 Gary V. Vaughan <gary@gnu.org>
6228 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
6229 values are returned as part of the internal interface, so they
6231 * m4/private.h: ...to here.
6232 * m4/macro.c (expand_token): Check for out of range
6233 m4_peek_input() results before looking up in the syntax table.
6234 (collect_arguments): Ditto.
6236 * NEWS: Note `$' syntax class.
6238 2003-07-08 Paul Eggert <eggert@twinsun.com> and
6239 Gary V. Vaughan <gary@gnu.org>
6241 Conform to POSIX if the POSIXLY_CORRECT environment is set.
6242 --traditional `define' now smashes all the definitions.
6244 * NEWS: Explain this.
6245 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
6246 (Extensions): Explain that extensions that are incompatible with
6247 POSIX are disabled if POSIXLY_CORRECT is set.
6248 (Incompatibilities): Remove.
6249 (Define, Other Incompat): Explain difference
6250 between GNU and POSIX behavior of define, pushdef, popdef.
6251 * m4/m4.c (m4_get_posixly_correct_opt): New undef.
6252 * m4/m4module.h (m4_context_opt_bit_table): Add POSIXLY_CORRECT entry.
6253 * m4/m4private.h (M4_OPT_POSIXLY_CORRECT_BIT): New macro.
6254 (m4_get_posixly_correct_opt): New macro.
6255 * m4/m4macro.c (m4_process_macro): Disable $10, $abc etc. if
6257 * modules/m4.c (builtin_functions): defn now takes any number of args.
6258 (builtin_define): Smash all the definitions if
6260 (builtin_defn)): Allow any number of arguments.
6261 (builtin_undivert): Do not allow nonnumeric arguments
6263 * src/main.c (main): Set posixly-correct behavior if either
6264 POSIXLY_CORRECT is set, or if -G is given.
6265 * tests/builtins.at: New test for smashed definitions.
6267 2003-06-27 Gary V. Vaughan <gary@gnu.org>
6269 * doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
6270 * m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
6271 not to slow the parser down.
6272 (M4__IS_STRING): New macro to test string syntax class membership.
6273 * m4/syntax.c: Adjust docucomment.
6274 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
6275 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
6276 * m4/input.c (init_builtin_token): Comment typo.
6277 (m4__next_token): Comment typo.
6278 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
6279 by using the new M4__IS_STRING macro.
6280 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
6281 variable references in macro expansions.
6283 * doc/m4.texinfo (Eregexp and Regexp): Typo.
6284 (Epatsubst and Patsubst): Typo.
6287 2003-06-26 Gary V. Vaughan <gary@gnu.org>
6289 Move the global variables that pertain to syntax to a new `struct
6290 m4_syntax_table', and then add one of these to `struct m4'. The
6291 ripple effect through the code to both change formerly global
6292 references, and make sure a suitable context is available in
6293 lexical scope is disproportionately large compared to the size of
6294 the change proper. This change is a large part of decoupling
6295 syntax.c from the rest of the code that uses it.
6297 * m4/m4private.h (struct m4): Add a syntax field.
6298 * m4/m4.c (m4_create): Initialise it,
6299 (m4_delete): Recycle it.
6300 (m4_get_symtab): Remove hand coded version...
6301 (m4_get_symbol_table): ...and generate this with cpp. Changed all
6303 * m4/m4module.h (m4_context_field_table): Add an extra field so we
6304 can generate m4_get_symbol_table. Add a new row for
6305 m4_get_syntax_table.
6306 (M4SYNTAX): Syntactic sugar for module writers.
6307 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
6308 (m4_syntax_table): New home for syntax related formerly global
6310 * m4/m4private.h (struct m4_syntax_table): Define it.
6311 * m4/input.c (m4_input_init): Initialisation of these formerly
6312 global variables moved...
6313 * m4/syntax.c (m4_syntax_create): ...to here.
6314 * m4/input.c (m4_input_exit): And similarly, recycling of the
6315 memory used by those values moved...
6316 * m4/syntax.c (m4_syntax_delete): ...to here.
6317 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
6318 Moved to m4/m4private.h.
6319 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
6320 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
6321 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
6322 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
6323 objects. Changed all callers that used to directly access the
6325 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
6326 Removed and incorporated into m4_syntax_table structure.
6327 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
6328 * m4/syntax.c (m4_set_syntax): Now returns an error status,
6329 instead of requiring a `struct m4' to generate its own errors.
6330 Changed all callers.
6331 * src/main.c (main): Now that the syntax table is initialised as
6332 part of m4_create, we have to manually wipe the syntax entries if
6333 we are about to read a frozen file.
6335 2003-06-26 Gary V. Vaughan <gary@gnu.org>
6337 * doc/STYLE: Added notes on callback naming schemes.
6339 * m4/module.c (m4_set_module_macro_table)
6340 (m4_set_module_builtin_table): Declarations weren't changed when
6341 definitions were renamed on 2003-06-19.
6343 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
6344 neither used nor particularly appropriate since it exposes the
6345 internal workings of the hash module. I haven't yet decided
6346 whether to remove it entirely.
6348 2003-06-20 Gary V. Vaughan <gary@gnu.org>
6350 Two related changes, and a huge knockon effect throughout the
6351 source: Moved the option variables out of global space and into
6352 `struct m4'; made `m4_symtab' a real datatype, so that its api
6353 is not marred passing `struct m4' around just so it can decide
6354 whether to keep traced symbol names or not. Added setters and
6355 getters for the formerly global option variables, and obviously
6356 changed a vast number of functions to take a `struct m4' and use
6357 the getter funcs to find option values.
6359 * m4/utility.c (interactive, sync_output, debug_level)
6360 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
6361 (max_debug_argument_length, warning_status, nesting_limit)
6362 (discard_comments): Removed.
6363 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
6364 (debug_level, max_debug_argument_length, prefix_all_builtins)
6365 (suppress_warnings, discard_comments, interactive, sync_output):
6366 Removed from here...
6367 * m4/m4private.h (struct m4): ...and equivalent fields added to
6369 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
6370 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
6371 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
6372 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
6373 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
6374 macros for the new fields.
6375 * m4/m4module.h (m4_context_field_table)
6376 (m4_context_opt_bit_table): Helper macros used to generate
6377 prototypes, setters and getters for new option fields
6379 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
6380 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
6381 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
6382 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
6383 (m4_get_interactive_opt, m4_get_sync_output_opt)
6384 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
6385 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
6386 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
6387 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
6388 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
6389 setter and getter functions generated by cpp from
6390 m4_context_field_table and m4_context_opt_bit_table, exported as
6391 part of the module api. Changed all callers.
6392 * m4/symtab (struct m4_symtab): Used as the concrete type for
6394 (m4_symtab_create): Allocate and initialise a new struct.
6395 (m4_symtab_apply): New function that works like m4_hash_apply, but
6396 with different callbacks specific to symbol tables. Changed all
6398 (symbol_destroy, arg_destroy, arg_copy): Renamed
6399 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
6400 they have unused parameters for a reason!
6401 (dump_symbol_CB): New callback to dump the contents of a single
6403 (symtob_dump): Rewritten in terms of dump_symbol_CB.
6404 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
6405 Changed all callers.
6406 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
6407 of the contained `m4_symtab' at the `no_gnu_extensions' field.
6408 Although I'm not convinced these semantics are correct, they are
6409 at least consistent with how things were before this delta. Also
6410 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
6412 2003-06-19 Gary V. Vaughan <gary@gnu.org>
6414 Tie down the interface to libm4 some more. Make more structures
6415 opaque to modules by moving them to m4private.h, and writing
6416 setters and getters. To win back the speed penalty for doing this
6417 also wrote macroized versions that do know about structure layout
6418 in m4private.h and #include that file into modules when NDEBUG is
6419 defined at compile time. There are still some accessor macros in
6420 m4private.h that need to go, but that is not necessary to clean
6423 * m4/m4module.h (m4_symbol_type): Moved...
6424 * m4/m4private.h (m4__symbol_type): ...to here.
6425 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
6426 (m4_set_symbol_traced, m4_set_symbol_name_traced)
6427 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
6428 (m4_get_symbol_func, m4_symbol_value_create)
6429 (m4_symbol_value_delete, m4_set_symbol_value_text)
6430 (m4_set_symbol_value_func): New exported api to symbols.
6431 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
6432 and m4_is_symbol_value_func.
6433 * m4/m4module.h: Prototype these guys.
6434 * m4/module.c (m4_set_module_macro_table)
6435 (m4_set_module_builtin_table): Make these static, there is no
6436 reason to pollute the api with them.
6437 * m4/m4private.h: Reformatting.
6438 (m4_get_symtab): Only define when NDEBUG is defined.
6439 (m4_get_symbol_value, m4_get_symbol_traced)
6440 (m4_set_symbol_traced, m4_set_symbol_name_traced)
6441 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
6442 (m4_get_symbol_func, m4_symbol_value_create)
6443 (m4_symbol_value_delete, m4_set_symbol_value_text)
6444 (m4_set_symbol_value_func): Macro implementations of the new
6445 functions when NDEBUG is defined.
6446 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
6447 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
6448 Superceded by the above. All callers changed.
6449 (M4ARG): Removed. This is no longer different to the
6450 m4/m4module.h definition.
6451 * modules/gnu.c, modules/m4.c: Only include m4private.h when
6452 NDEBUG is defined. That way we exercise the same (albeit slower)
6453 api that external modules must use.
6455 2003-06-18 Gary V. Vaughan <gary@gnu.org>
6457 Renamed some of the types and their accessors to make more sense.
6458 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
6459 has a stack of SYMBOL_VALUEs.
6461 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
6462 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
6463 m4_get_symbol_value_type, m4_get_symbol_value_text,
6464 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
6465 Changed all callers.
6466 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
6467 (m4_get_token_type): Renamed
6468 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
6469 to the internal api.
6470 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
6472 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
6473 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
6474 (m4__token_type): Moved here from m4module.h.
6475 (m4__next_token): Renamed from m4_next_token.
6476 * m4/symtab.c: Removed some of the parameterised macro support
6477 functions for modularisation later.
6478 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
6479 m4_hash_dup to perform a true deep copy of the SRC.
6480 (arg_copy): Callback for m4_symbol_value_copy.
6481 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
6482 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
6483 m4_get_symbol_value_func. Changed all callers.
6485 2003-06-18 Gary V. Vaughan <gary@gnu.org>
6487 Tidy up style of hash.[ch] in accordance with doc/STYLE.
6489 * m4/hash.c: Internal symbol renaming and formatting.
6490 (m4_hash_dup): New function to facilitate deep copies of hash
6492 (m4_hash_apply_func): Returns a void* now, which is a richer type
6493 for returning exceptions (NULL means keep going).
6494 (m4_hash_apply): Ditto.
6495 * m4/hash.h: Declare exported symbols with an explicit extern.
6498 2003-06-17 Gary V. Vaughan <gary@gnu.org>
6500 Still refactoring furiously. This delta represents a change in
6501 semantics to symtab.c. Instead of building temporary m4_tokens
6502 in the caller, and copying fields in the methods, we now create
6503 the actual m4_token for hashing in the caller so the methods just
6504 slot them in directly. Also, this means that we don't lookup a
6505 symbol and get back an allocated but VOID token to copy fields
6506 into, we create the token we want to push and pass that to
6507 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
6508 a few other small changes to stop knowledge of the implementation
6509 of symtab.c leaking out into other files.
6511 * m4/macro.c (expand_argument): Comment typo corrected.
6512 * m4/symtab.c (symtab_fetch): New function to fetch the address of
6514 (m4_symbol_pushdef): Take an extra value parameter and use this
6515 directly as the new top of the value stack. All callers changed
6516 to build a token and pass responsibility for memory in, rather
6517 than copying as we used to.
6518 (m4_symbol_define): Also use the new value parameter directly as a
6519 replacement for the top of the value stack. All callers changed
6520 to build a token as above.
6521 (m4_set_symbol_traced): New function to set the traced bit on the
6522 named symbol, creating it if necessary.
6523 (symbol_popval): The guts of the old m4_symbol_popdef.
6524 (m4_symbol_popdef): Use it.
6525 * m4/builtin.c (m4_symbol_set_token): Removed,
6526 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
6528 * m4/module.c (m4_set_module_builtin_table)
6529 (m4_set_module_macro_table): ...with these more orthogonal
6531 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
6532 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
6534 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
6535 (m4_arg_signature_parse): Moved...
6536 * m4/symtab.c: ...to here.
6537 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
6538 screw something up. Moved...
6539 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
6540 actually does a proper deep copy of source to dest.
6542 2003-06-16 Gary V. Vaughan <gary@gnu.org>
6544 Further refactoring to stabilise the module API. Renaming some
6545 functions for orthogonality, and judicious definition migration to
6546 move things out of the set of exported symbols.
6548 * doc/STYLE: New file. Notes on coding style.
6549 * m4/m4module.c: Updated bitrotted docucomment at the top of the
6551 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
6552 m4_get_module_name, m4_get_module_builtin_table,
6553 m4_get_module_macro_table which are verb phrases. Changed all
6555 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
6557 * m4/module.c (m4_set_module_builtin_table)
6558 (m4_set_module_macro_table): ...here, and renamed. Changed all
6560 * m4/m4module.c (m4_module_data): This...
6561 * m4/m4private.c (struct m4_module_data): ...and this...
6562 * m4/module.c (module_data) ...consolidated here and no longer
6563 exported. Changed all callers.
6565 2003-06-16 Gary V. Vaughan <gary@gnu.org>
6567 Begin work on lifting the curse of the global variables. To start
6568 with create a `struct m4' context container, and replace
6569 `m4__symtab' with `context->symtab' throughout. This means
6570 initialising a context container in main, and adjusting many
6571 functions between main and the module entry points so that the
6572 container gets passed through. It would have been nice to
6573 defer this until after 1.5, but it has a major effect on the
6574 user's module writing ABI, so it needs to be addressed now - at
6575 least in the areas that impact the ABI. An interrelated change
6576 in the symtab API removes the dependency on a global symbol table,
6577 and instead focuses on a passed table (from the context
6580 * TODO: Reminders for finishing context functionality.
6581 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
6582 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
6583 global variables and eventually allow m4 to be reentrant.
6584 * m4/m4private.h (m4): Define the new structure here...
6585 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
6586 don't carry the overhead of a function call.
6587 * m4/m4module.h: Prototype extern functions from m4/m4.c.
6588 (m4): Declare type for new struct m4 objects.
6589 (M4SYMTAB): User macro to ease finding the symbol table for the
6590 current context for module developers.
6591 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
6593 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
6594 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
6595 (m4_call_macro, m4_dump_symbols, m4_expand_input)
6596 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
6597 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
6598 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
6599 m4* context parameter. Changed definitions and all callers.
6600 (m4_symtab): Alias for m4_hash to decouple the
6601 m4_symtab api from m4_hash.
6602 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
6604 (m4_symtab_create): New function to return an initialised
6606 (m4_symtab_delete): New function to delete an m4_symtab's memory.
6607 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
6608 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
6609 instead of simply using the global m4__symtab. Changed
6610 definitions and all callers.
6611 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
6612 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
6613 * src/main.c (main): Create a context and use that instead of the
6614 former global m4__symtab.
6616 2003-06-13 Gary V. Vaughan <gary@gnu.org>
6618 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
6619 to the callback. Callbacks should not need to hardcode the
6620 hashtable they are working from, nor should we have to waste the
6621 userdata parameter to pass the table in.
6622 * m4/hash.h (m4_hash_apply_func): Require the initial table
6624 * m4/symtab.c (symtab_destroy): Use the passed table instead
6625 of hardcoding m4__symtab.
6626 (m4_symbol_popdef): Don't use the userdata parameter to pass the
6627 table to arg_destroy.
6628 (arg_destroy): Use the hash parameter, ignore userdata.
6629 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
6631 (traceon, traceoff): Call set_trace with the extra initial
6634 2003-06-13 Gary V. Vaughan <gary@gnu.org>
6636 More refactoring to stabilise the module api, this time for
6637 symtab.c. Additionally, start to pay attention to function names
6638 that don't contain a verb like they should.
6640 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
6641 wrapper for m4_hash_apply to decouple the symtab module from the
6643 (m4_symbol_builtin, m4_symbol_macro): Renamed to
6644 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
6646 (m4_symbol_delete): Create a macro version to save a function
6648 (m4_token_t, m4_data_t): These violate the POSIX reserved
6649 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
6651 (m4_token_type): Renamed to m4_token_get_type.
6652 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
6653 (m4_symtab_exit): Removed from the exported module
6655 * m4/m4private.h (m4__symtab, m4__symtab_init)
6656 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
6657 renamed and added to the internal api. Changed all callers.
6658 (m4_symtab_apply): A faster macro version of the function for
6659 users of the internal api.
6660 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
6661 symbol_destroy and arg_destroy.
6662 (symtab_debug): Added a prototype.
6663 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
6664 so that callers in this file get the faster macro versions from
6667 2003-06-12 Gary V. Vaughan <gary@gnu.org>
6669 Refactoring modules to rationalise the API into an external
6670 documented (eventually!) API for use by modules in the `m4_'
6671 namespace declared in m4/m4module.h, an internal API between the
6672 source files we ship (including our shipped modules) in the `m4__'
6673 namespace declared in m4/m4private.h and making the rest as
6674 cohesive as possible with liberal use of the `static' keyword.
6675 This change represents an audit to m4/module.c along these
6678 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
6679 Removed. No longer used.
6680 (m4_module_close): Removed prototypes.
6681 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
6682 from the exported module api...
6683 * m4/m4private.h (m4__module_init, m4__module_open)
6684 (m4__module_exit): ...and renamed and added to the internal api.
6685 Changed all callers.
6686 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
6687 Centralised definitions after renaming...
6688 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
6689 (M4_FINISH_SYMBOL): ...and removing from here.
6690 (m4_module_dlerror, m4_module_remove, m4_module_close)
6691 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
6692 module_remove, module_close and caller_id.
6693 (MODULE_SELF_NAME): New macro to make reporting self errors
6695 (m4_module_load, module_close, module_remove): Use it.
6696 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
6698 * src/main.c (main): Use it.
6700 2003-06-12 Gary V. Vaughan <gary@gnu.org>
6702 * README: Remove references to --enable-changeword, which has been
6703 removed from the code.
6705 2003-06-11 Gary V. Vaughan <gary@gnu.org>
6707 Getting rid of the annoying bug with configure --enable-debug,
6708 which spewed -e: command not found errors. This was an interaction
6709 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
6710 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
6711 branch-1-5) to get the full fix.
6713 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
6714 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
6715 and then use the probed value of $SED.
6716 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
6717 this, it messes up the AC_REQUIRE stack.
6719 2003-06-10 Gary V. Vaughan <gary@gnu.org>
6721 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
6722 the destroy callback.
6723 (m4_arg_destroy): Use the hash address to free the hash node key
6726 2003-06-06 Gary V. Vaughan <gary@gnu.org>
6728 First cut at formal parameters in macros.
6730 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
6731 * m4/xstrzdup.c: New file.
6732 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
6733 associative array of parameter names to details.
6734 (m4_symbol_token): Capture macro names with parameter lists.
6735 (m4_arg_signature_parse): And build an associative array to hang
6736 from the symbol structure to map names to details.
6737 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
6738 m4_hash_resize idiom. Now that we potentially add a little hash
6739 table to many of the entries in the symbol table, added an extra
6740 arg to set the initial size. Changed all callers.
6741 (m4_hash_apply): New function that is basically a generalised
6743 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
6744 all callers to call m4_hash_apply instead.
6745 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
6746 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
6747 m4_arg_signature association that might be attached to the symbol,
6748 * m4/hash.h (m4_hash_apply_func): Replacement type for...
6749 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
6750 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
6752 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
6753 (M4_IS_IDENT): Detect characters that can be safely used in
6755 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
6756 * m4/macro.c: Corrected grammar in some comments. Use `token'
6757 rather than `td' for m4_token variables.
6758 (m4_process_macro): If we find a dollar followed by some
6759 M4_IS_IDENT characters, replace that with the contents of the argv
6760 entry with offset stored in the m4_token_arg associated with the
6761 collected identifier.
6763 2003-06-05 Gary V. Vaughan <gary@gnu.org>
6765 Begin preparations for supporting formal parameters in m4 macros.
6767 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
6768 the details of a formal parameter.
6769 (m4_token): Add an arg_signature member to hold a hash table for
6770 looking up formal parameters.
6771 * m4/input.c: Update more bitrotted comments.
6772 (m4_push_builtin): Initialise arg_signature member.
6773 (init_builtin_token): Copy arg_signature member.
6774 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
6775 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
6777 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
6778 (m4_macro_pushdef, m4_macro_define): ...these, And...
6779 (m4_symbol_token): ...wrapped around this new function, which
6780 vastly simplifies the arguments required by the functions it
6782 Changed all callers.
6784 2003-06-05 Gary V. Vaughan <gary@gnu.org>
6786 * m4/macro.c: Format changes.
6788 2003-06-04 Gary V. Vaughan <gary@gnu.org>
6790 * m4/input.c: Updated various bitrotted comments.
6791 (m4_push_builtin): Just pass the whole m4_token, rather than
6792 extracting all the fields in the caller. This also allows us to
6793 check the token type for consistency.
6794 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
6795 Renamed to builtin_funcs, builtin_peek, builtin_read,
6796 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
6797 the code. Changed all callers.
6798 (struct input_block): Similarly renamed u_m member to u_b, and
6799 changed all callers.
6800 (m4_next_token): Use bzero to initialise the data fields.
6801 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
6803 2003-05-29 Gary V. Vaughan <gary@gnu.org>
6805 These changes were necessary to get m4 to build on my iBook
6806 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
6807 (GCC) 3.1 20020420 (prerelease)":
6809 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
6810 inclusion of module loader headers.
6811 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
6812 * m4/Makefile.am: Ditto.
6813 (libm4_la_LIBADD): Added $(LTLIBINTL).
6814 * m4/utility.c (program_name): Removed declaration in favour of
6815 the one already in error.c!
6816 * m4/m4module.h (program_name): Define to program_invocation_name
6817 when using GNU C library. Use an explicit extern declaration.

6830 * m4/error.h (error, error_at_line, error_print_progname)
6831 (error_message_count, error_one_per_line): Ditto.
6832 * m4/ltdl.c: Update from CVS libtool.

6847 2002-11-04 Akim Demaille <akim@epita.fr>
6849 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
6851 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
6853 2002-11-04 Akim Demaille <akim@epita.fr>

6857 2002-11-04 Akim Demaille <akim@epita.fr>
6859 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
6860 used as `external', and Libtool 1.4.3.
6862 (LTLIBOBJS): Don't play with it.
6864 * Makefile.am (SUBDIRS): Remove intl.
6865 (ACLOCAL_AMFLAGS): Add -I config.
6866 (EXTRA_DIST): Add config/config.rpath.
6869 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
6871 2002-05-29 Gary V. Vaughan <gary@gnu.org>
6873 Preparations for refactoring syntax tables to allow reverse
6874 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
6875 speed of normal lookups in an array of unsigned short.
6877 * m4/input.c (single_quotes, single_comments, use_macro_escape):
6879 * m4/m4private.h (m4__single_quotes, m4__single_comments,
6880 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
6881 is for internal symbols which unavoidably pollute the global
6882 namespace, but are not published APIs.
6883 Adjusted all callers.
6884 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
6885 m4_set_comment, m4_set_syntax, set_syntax_internal,
6886 unset_syntax_attribute): Moved from this file...
6887 * m4/syntax.c: New. ...to this file.
6888 Also added an m4_syntax_exit stub for orthogonality.
6889 * src/main.c (main): Use it.
6890 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
6891 * m4/m4module.h: Reformatting. New prototypes.
6893 2002-05-29 Gary V. Vaughan <gary@gnu.org>
6895 * bootstrap (aclocal_apiversion): The aclocal apiversion is
6896 distinct from the automake release number (in that the apiversion
6897 apparently has no micro-version-component).
6898 (aclocal_apilibdir): Use it.
6900 2002-05-28 Gary V. Vaughan <gary@gnu.org>
6902 * m4/hash.c (m4_hash_resize): New function.
6903 * m4/hash.h: Add prototype.
6904 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
6905 benchmarking to find a good value for, say, autoconf. This is
6906 already a little quicker than before for me.
6908 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
6909 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
6911 * m4/hash.h: Adjust prototypes.
6913 2002-01-22 Akim Demaille <akim@epita.fr>
6915 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
6917 * tests/Makefile.am (package.m4): New.
6918 * tests/atlocal.in: Adjust to CVS Autotest.
6919 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
6920 * configure.ac: LIBOBJ is a forbidden string.
6921 Simplify AM_INIT_AUTOMAKE invocation.
6922 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
6925 2002-01-21 gettextize <bug-gnu-utils@gnu.org>

6929 2001-10-19 Akim Demaille <akim@epita.fr>
6931 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.

6951 2001-10-16 Gary V. Vaughan <gary@gnu.org>
6953 * m4/symtab.c (m4_symbol_destroy): This function calls
6954 m4_symbol_popdef, which recycles a symbols memory when the last
6955 definition is popped. Since we were passing the address of the
6956 symbol name found in the symbol table, and it was being removed
6957 partway through m4_symbol_destroy() we were referencing freed
6958 memory for the balance of the function. Now we take a copy of the
6959 symbol name tring and use that as a key into the symbol
6960 table... that way if the original symbol name is freed, the copy

6965 * m4/ltdl.c: Update.
6967 2001-10-13 Akim Demaille <akim@epita.fr>
6969 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
6970 Don't gettextize internal error messages.
6972 2001-10-13 Akim Demaille <akim@epita.fr>
6974 * tests/macros.at (Arity and defn): New failing test.
6975 (Arity, defn, and freeze): New.
6977 Fix `Arity and defn'.
6979 * m4/input.c (m4_push_macro): Don't forget the arity.
6980 * modules/m4.c (defn): Likewise.
6982 2001-10-13 Akim Demaille <akim@epita.fr>
6984 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
6986 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
6987 (Propagation of traceon, Propagation of --trace): this new file.
6989 2001-10-13 Akim Demaille <akim@epita.fr>
6991 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
6992 interface instead of (name, argc...).
6993 Upon failure, specify which argument was guilty.
6996 2001-10-13 Akim Demaille <akim@epita.fr>
6998 * modules/evalparse.c: Save translators' time: don't translate
6999 internal error messages.
7000 (m4_evaluate): Simplify/normalize error messages.
7001 * doc/m4.texinfo (Eval): Adjust.
7003 2001-10-13 Akim Demaille <akim@epita.fr>
7005 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
7006 where no checking is needed.
7007 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
7008 interface instead of (name, argc...).
7010 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
7013 2001-10-13 Akim Demaille <akim@epita.fr>
7015 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
7016 exclude the builtin name from the count.
7017 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
7018 calling ifelse with a single argument is valid.
7019 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
7020 with 1 and 2 args, mostly to strengthen the test suite.
7022 2001-10-13 Akim Demaille <akim@epita.fr>
7024 * m4/output.c (m4_make_diversion, m4_insert_file)
7025 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
7027 2001-10-12 Gary V. Vaughan <gary@gnu.org>
7029 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
7030 since we call these things builtins in the rest of the code!
7032 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
7034 2001-10-12 Gary V. Vaughan <gary@gnu.org>
7036 Rather than forcing each builtin definition to manage its own
7037 argument range checking, tabulate the maxima and minima for all
7038 builtins in each module. This forces us to consider what the
7039 valid ranges for each builtin should be, and moves the checking
7040 code out of each builtin implementation and into the builtin
7041 caller infrastructure.
7043 * m4/m4module.h (struct m4_builtin): Add argument minima and
7045 * m4/m4private.h (struct m4_token): Reflect them here too.
7046 * m4/input.c (struct input_block): ...and here.
7047 (m4_token_copy): New function for token copying.
7048 (init_macro_token): Copy them from a token to the input stack.
7049 (m4_next_token): Don't forget to initialise them for text
7051 * m4/macro.c (expand_argument): Use m4_token_copy, and also
7052 check argument counts before calling the builtin handler.
7053 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
7054 (m4_symbol_macro): Likewise.
7055 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
7056 parameters. Updated all callers.
7057 (m4_builtin_define): Ditto.
7058 (m4_macro_pushdef, m4_macro_define): Ditto.
7059 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
7060 * modules/evalparse.c: Declare argument counts for defined
7061 builtins and remove explicit calls to m4_bad_argc().
7062 * modules/gnu.c: Ditto.
7063 * modules/load.c: Ditto.
7064 * modules/m4.c: Ditto.
7065 * modules/modtest.c: Ditto.
7066 * modules/mpeval.c: Ditto.
7067 * modules/perl.c: Ditto.
7068 * modules/shadow.c: Ditto.

7070 * modules/time.c: Ditto.
7073 2001-10-10 Gary V. Vaughan <gary@gnu.org>
7075 The trace semantics now attach the trace bit to a symbol name.
7076 For as long as a traceon(`foo') is active, calls to foo will be
7077 traced regardless of intervening undefines or module unloads.
7078 Fixed the flag propogation issues differently to the fixes
7079 reverted with the last attempt at nailing down trace:
7081 * m4/m4private.h: This file is not visible outside of the m4
7082 source tree, so I removed all the `M4_' and `m4_' prefixes to save
7083 on typing. Updated all clients.
7084 (m4_token): New typedef contains the fields that need to be passed
7085 around with the low level tokeniser.
7086 (m4_token_data): Removed.
7087 (m4_symbol): Now contains the traced flag again.
7088 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
7089 the trace bit set. This change is contained entirely within this
7090 module and doesn't leak out into the callers. Updated all
7092 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
7093 new fields in m4_token. Updated all clients.
7094 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
7095 that `groks_macro_args' and `blind_if_no_args' flags are retained
7096 when defn() results are passed around in m4 code. Updated all
7098 (m4_builtin_define): Ditto.
7099 (m4_macro_pushdef, m4_macro_define): Ditto.
7100 * m4/input.c (struct input_block): Add a flags field to facilitate
7102 (m4_push_macro): ...use it.
7103 (init_macro_token): Retrieve it.
7104 (m4_next_token): Initialise it.
7105 * m4/macro.c (expand_argument): Copy it.
7106 * m4/m4module.h: Adjust.
7107 * tests/builtins.at: Adjust the expected output of the trace
7108 tests to reflect the change in semantics.
7109 * tests/modules.at (modules: trace): Check that unloading a
7110 module which supplies a traced symbol definition doesn't lose te
7113 2001-10-07 Gary V. Vaughan <gary@gnu.org>
7115 * modules/gnu.c (m4_macro_table): Display the timetamp when
7116 expanding __m4_version__.
7118 * configure.ac (--with-modules): Forgot a comma in the
7119 AC_HELP_STRING parameter list.
7121 2001-10-05 Gary V. Vaughan <gary@gnu.org>
7123 * bootstrap: Remove aclocal.m4t when it is no longer required.
7125 2001-10-05 Akim Demaille <akim@epita.fr>
7127 * tests/Makefile.am: Adjust for gnuprog2.
7128 * tests/m4.in: There can be a leading path.
7129 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
7130 * tests/testsuite.at: Adjust to the most recent Autotest.
7131 (AT_CHECK_M4_FILTER): Fix and rename as...
7133 * tests/others.at: Use it.
7135 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
7136 variable in shell scripts, one uses `$'...
7138 2001-10-04 Gary V. Vaughan <gary@gnu.org>
7140 * configure.ac: `rm -f $m4_getopt_h' was lost.
7142 2001-10-04 Gary V. Vaughan <gary@gnu.org>
7144 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
7145 time. Define it for config.h in order to...
7146 * src/main.c (main): ...display the timestamp for --version.
7148 2001-10-04 Akim Demaille <akim@epita.fr>
7150 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
7151 previous builtins `regexp' and `patsubst'.
7152 (regexp, patsubst): Use them.
7153 (eregexp, epatsubst): New builtins.
7154 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
7155 (Epatsubst and Patsubst, Eregexp and Regexp): these.
7156 (Extensions): More info on REs.
7158 2001-10-04 Akim Demaille <akim@epita.fr>
7160 * modules/modtest.c (init_handler): Consistently output to stderr.
7161 (finish_handler): New.
7162 (test): The `if' is an `assert'.
7163 * tests/modules.at: Adjust.
7165 2001-10-04 Akim Demaille <akim@epita.fr>
7167 * m4/utility.c (m4_bad_argc): Detail the mismatches.
7169 2001-10-01 Akim Demaille <akim@epita.fr>
7171 * tests/generate.awk: Tag the tests with `documentation'.
7172 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
7173 Use the make the existing modtest tests more uniform, and complete
7174 the set of possibilities.
7176 2001-10-01 Akim Demaille <akim@epita.fr>
7178 * config/gmp.m4: Consult the user before using GMP: use
7180 * configure.ac: Adjust.
7181 * modules/gmp.c: No protection needed as the module is not built
7184 2001-10-01 Akim Demaille <akim@epita.fr>
7186 * tests/generate.awk: Remove debugging code.
7187 (fatal): Specify the current location.
7189 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
7190 * modules/gnu.c, modules/m4.c: Use M4ARG.
7192 2001-10-01 Akim Demaille <akim@epita.fr>
7194 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
7195 (m4_regexp_compile): New.
7196 (regexp, patsubst): Use it.
7198 2001-09-30 Gary V. Vaughan <gary@gnu.org>
7200 Reinstate the memory handling improvements from the patch I just
7201 reverted. Relevant ChangeLog entries repeated here:
7203 * m4/module.c (m4_module_remove): New function that holds the core
7204 of the old m4_module_unload.
7205 (m4_module_unload): Use it.
7206 (m4_module_unload_all): When we know the modules will never be
7207 used again (i.e. on exit), free up as much module memory as
7208 possible. There are still some artifacts from resident modules
7209 living inside ltdl.c, but everything else is freed.
7210 * m4/debug.c (m4_debug_exit): Free memory allocated in
7212 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
7213 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
7214 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
7215 * m4/m4module.h: Updated prototypes.
7216 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
7217 * m4/hash.h: Updated prototypes.
7218 * src/main.c (main): Use all these new functions to clean up as
7219 much memory as possible before exit.
7221 2001-09-30 Gary V. Vaughan <gary@gnu.org>
7223 Reverted my large patch for removing the old m4_symbol
7224 structure on 2001-09-20. We are still not happy about the way
7225 trace works in conjunction with defn and undefine, and leaving
7226 the reverted patch active prevents us from moving the traced
7227 bit from the definition back to the symbol.
7229 2001-09-30 Gary V. Vaughan <gary@gnu.org>
7231 * configure.in: Moved to...
7232 * configure.ac: ...here. Added a libtool like timestamped
7233 banner, and tidied up the libltdl cruft.
7234 * config/mkstamp: Script to extract a timestamp from ChangeLog.
7235 * modules/Makefile.am (INCLTDL): Removed. This is required
7236 only when libltdl is configured in a subdirectory.
7237 * src/Makefile.am: Ditto.
7238 (LIBADD_DL): No need to add this again, libtool already knows
7239 that libm4.la depends on it.
7240 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
7243 * TODO: stackovf.c is basically broken.
7244 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
7246 2001-09-28 Akim Demaille <akim@epita.fr>
7248 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
7250 2001-09-27 Akim Demaille <akim@epita.fr>
7252 * tests/m4.in: Don't use short options.
7253 Simplify the stderr signature normalization.
7255 2001-09-27 Akim Demaille <akim@epita.fr>
7257 tests/m4 shall be position independent.
7261 * tests/testsuite.at: No args to AT_INIT.
7262 * configure.in, tests/Makefile.am: Adjust.
7264 2001-09-22 Akim Demaille <akim@epita.fr>
7266 Autotest has changed again.
7268 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
7269 (package.m4): Remove.
7270 * configure.in: Adjust to LIBADD_GMP.
7272 2001-09-21 Gary V. Vaughan <gary@gnu.org>
7274 * config/gmp.m4 (AC_ARG_WITH): Removed.
7275 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
7276 (AC_LIB_GMP): When performing a test compile against libgmp,
7277 include the header gmp.h if possible, and link against -lgmp. If
7278 they both work define USE_GMP.
7279 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
7280 (mpeval_LTX_init_func): Complain on load that there was no libgmp
7283 2001-09-20 Gary V. Vaughan <gary@gnu.org>
7285 * m4/evalparse.c: Moved to...
7286 * modules/evalparse.c: ...here. This code is shared between
7287 modules/mpeval.c and modules/m4.c, so there is no need to pollute
7288 the libm4 API with its details. Moderately rewritten to interface
7289 into its clients more simply.
7290 * m4/eval.c: Deleted. Migrated functionality to...
7291 * modules/m4.c: ...here.
7292 (builtin_eval): Implemented in terms of the new interface style.
7293 * modules/mpeval.c (builtin_mpeval): Ditto.
7294 * m4/m4module.h: Removed references to the former m4/eval.c.
7295 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
7296 (EXTRA_libm4_la_SOURCES): Deleted.
7297 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
7298 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
7300 2001-09-20 Akim Demaille <akim@epita.fr>
7302 * config/gmp.m4 (AM_WITH_GMP): Rename as...
7304 By default, use gmp.
7306 * configure.in: Adjust.
7307 Use Automake conditionals for USE_GMP.
7308 Always compute sizeof (long long int).
7309 This was a bug BTW, as `eval' (not `mpeval') depends on it:
7310 before, it was used _only_ if mpeval was not activated.
7311 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
7312 (mpeval_la_LIBADD): New macros.
7313 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
7315 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
7316 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
7319 2001-09-20 Akim Demaille <akim@epita.fr>
7321 * tests/Makefile.am (package.m4): New.
7322 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
7324 2001-09-20 Gary V. Vaughan <gary@gnu.org>
7326 More cleanup. After the last patch, m4_symbol holds nothing but
7327 the head of a chain of m4_token_data. So I have removed the old
7328 m4_symbol, so that m4_token_data chains are stored directly in the
7329 value cell of a hash table node. But there's more... m4_symbol
7330 was a more natural name for the symbol value cell, and now that it
7331 is gone I have renamed the former m4_token_data structure to
7332 m4_symbol. This change turned out to be a pig to get right, since
7333 the original code didn't need to modify the value cell itself,
7334 since changing the chain happened inside the m4_symbol that used
7335 to be returned -- I had to pass the address of the value cell
7336 across various function calls, incase the head value changed. I
7337 also tightened up the memory management to help me find a nasty
7338 memory corruption bug that took me all night to track down...
7340 * m4/m4private.h (struct m4_symbol): Removed.
7341 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
7343 * m4/hash.c (m4_hash_iterator_value): Return the address of the
7344 value cell. Updated all callers.
7345 * m4/symtab.c: Took advantage of the simplification in the data
7346 structures to rewrite a lot of this file more simply. There is
7347 still some room for optimisation here, but we should tackle that
7348 systematically closer to the release.
7350 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
7351 revealed. This version is ahead of CVS libtool until I get chance
7352 to flush my changes.
7353 * m4/module.c (m4_module_remove): New function that holds the core
7354 of the old m4_module_unload.
7355 (m4_module_unload): Use it.
7356 (m4_module_unload_all): When we know the modules will never be
7357 used again (i.e. on exit), free up as much module memory as
7358 possible. There are still some artifacts from resident modules
7359 living inside ltdl.c, but everything else is freed.
7360 * m4/debug.c (m4_debug_exit): Free memory allocated in
7362 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
7363 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
7364 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
7365 * m4/m4module.h: Updated prototypes.
7366 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
7367 * m4/hash.h: Updated prototypes.
7368 * src/main.c (main): Use all these new functions to clean up as
7369 much memory as possible before exit.
7371 2001-09-18 Gary V. Vaughan <gary@gnu.org>
7373 The `traced' flag needs to be attached to the definition of a
7374 symbol rather than the current symbol containing the definition.
7375 Implementing this showed up some long standing post 1.4 bugs in
7376 flag propogation which I also fixed.
7378 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
7379 (struct m4_token_data): And add it back in here.
7380 * m4/input.c (init_macro_token): Propogate the traced flag
7382 * m4/macro.c (expand_argument): Ditto.
7383 * tests/builtins.at (trace2, trace3): New tests based on Akim's
7386 2001-09-08 Gary V. Vaughan <gary@gnu.org>
7388 * m4/m4private.h (struct m4_token_data): Simplified by removing
7389 the redundant `traced' flag, and one level of structure nesting.
7390 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
7391 * m4/input.c (init_macro_token): No need to initialise removed
7393 * m4/macro.c (expand_argument): No need to copy it either.
7394 * m4/utility.c (m4_token_data_func_traced): Or provide an access
7397 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
7398 dependant on multiple symbols with the same key, so preserving
7399 relative symbol order in each bucket during resizing is no longer
7400 required. The resize function is considerably faster as a result.
7402 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
7403 s/m4_symbol_insert/m4_symbol_define/g;
7404 s/m4_builtin_insert/m4_builtin_define/g;
7405 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
7407 2001-09-08 Gary V. Vaughan <gary@gnu.org>
7409 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
7410 commits, the m4_lookup_symbol dispatch function is split into
7411 specialised functions that must be called directly.
7413 * m4/m4module.h (m4_symbol_lookup_t): Removed.
7414 * m4/symtab.c (m4_lookup_symbol): Removed.
7415 (m4_symbol_builtin, m4_symbol_macro): New functions.
7416 * m4/builtin.c (m4_builtin_define): Split into...
7417 (m4_builtin_pushdef, m4_builtin_insert): ...these.
7418 (m4_macro_define): Split into...
7419 (m4_macro_pushdef, m4_macro_insert): ...these.
7420 * src/main.c (main): Set command line macros from `-D' parameters
7421 using `m4_macro_define'.
7423 2001-09-08 Gary V. Vaughan <gary@gnu.org>
7425 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
7426 this from m4_remove_table_reference_symbols().
7427 * m4/m4module.h, m4/module.c: Updated all references.
7429 2001-09-07 Akim Demaille <akim@epita.fr>
7431 * modules/stdlib.c, modules/times.c: Misc cleanups.
7433 2001-09-07 Akim Demaille <akim@epita.fr>
7435 * configure.in: We now need Autoconf 2.52e.
7436 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
7437 and `M4_SYMBOL_DELETE'.
7438 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
7439 * src/main.c (main): Adjust.
7441 2001-09-06 Gary V. Vaughan <gary@gnu.org>
7443 Fix the obstack.h problem once and for all! At configure time we
7444 can test for a system supplied obstack.h: depending on the
7445 result, we now generate system.h with an #include of the correct
7446 header. As a bonus, I've also added a --with-included-obstack,
7447 incase the user doesn't like the system obstack for some
7448 reason... and also we can test the shipped obstack on a system
7449 that has oe of its own. We also now need to be careful to add
7450 build directories to the include search path, since the generated
7451 system.h will be in the build tree.
7453 * configure.in (AC_CONFIG_FILES): Generate system.h from
7455 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
7456 include the system obstack header or the copy shipped with M4.
7457 Allow the user to override configure and force the build to use
7458 the shipped version.
7459 * m4/system-h.in: New file, template for...
7460 * m4/system.h: ...this. Now deleted.
7461 * m4/m4module.h: Include system.h before everything else.
7462 * src/freeze.c: Ditto.
7463 * m4/Makefile.am (dist-hook): Remove generated system.h.
7464 (INCLUDES): Check builddir for generated headers before checking
7466 * modules/Makefile.am (INCLUDES): Ditto.
7467 * src/Makefile.am (INCLUDES): Ditto.
7469 2001-09-05 Gary V. Vaughan <gary@gnu.org>
7471 * TODO: Remove the items that have been addressed already.
7473 2001-09-05 Akim Demaille <akim@epita.fr>
7475 * src/main.c (main): Standardize --version.
7477 2001-09-05 Akim Demaille <akim@epita.fr>
7479 * modules/format.c (format): Have a bigger `str'.
7481 2001-09-05 Akim Demaille <akim@epita.fr>
7483 Rationalize warnings, reporting the macro name as if it were a
7484 program name, and assertions.
7486 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
7488 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
7490 Use assert for internal errors.
7491 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
7493 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
7495 * tests/builtins.at (pushpop): Adjust.
7497 2001-09-05 Akim Demaille <akim@epita.fr>
7499 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
7502 2001-09-05 Akim Demaille <akim@epita.fr>
7504 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
7505 * m4/macro.c, m4/symtab.c: Adjust.
7507 2001-09-05 Akim Demaille <akim@epita.fr>
7509 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
7510 (m4_symbol_pop, m4_symbol_del): this.
7511 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
7512 (m4_symbol_popdef, m4_symbol_delete): New.
7513 (m4_lookup_symbol): Adjust.
7514 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
7516 2001-09-05 Akim Demaille <akim@epita.fr>
7518 * m4/m4module.h (m4_symbol_lookup): Rename as...
7519 (m4_symbol_lookup_t): this.
7521 2001-09-05 Akim Demaille <akim@epita.fr>
7523 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
7525 * m4/symtab.c (m4_lookup_symbol): Adjust.
7527 2001-09-03 Gary V. Vaughan <gary@gnu.org>
7529 Bootstrap will now work with Libtool 1.4.1 or higher:
7530 * bootstrap: Remove stale autom4te.cache files when
7532 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
7534 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
7535 libtool.m4 directly.
7536 Run libtoolize to refresh ltmain.sh.
7537 * config/ltmain.sh: Deleted.
7538 * acinclude.m4: Deleted.
7539 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
7541 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
7542 implementation for the cvs impaired libtool user.
7544 2001-09-03 Akim Demaille <akim@epita.fr>
7546 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
7548 Avoid using `default' in switch, as it hides useful compiler
7549 warnings when a case is forgotten.
7551 2001-09-03 Akim Demaille <akim@epita.fr>
7553 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
7554 is no such thing as `WITH_MODULES'.
7556 2001-09-03 Akim Demaille <akim@epita.fr>
7558 Improve the test suite's selfcontainedness.
7560 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
7561 (Include, Undivert): Tag the other input files.
7562 * tests/generate.awk: Catch `@comment file:'.
7563 `-I $src' is no longer needed.
7564 `next' is really like `return': the rest is skipped.
7565 Adjust to `input.m4'.
7566 (fatal): New function.
7567 * tests/foo, tests/incl.m4: Remove.
7569 2001-09-01 Gary V. Vaughan <gary@gnu.org>
7571 The shadowing mechanism and, infact, the whole symbol table
7572 implementation was creaking under the weight of the features piled
7573 on top of it. We now have a separate hash table module which will
7574 dynamically resize to keep symbol density withing good performace
7575 limits, and a new symtab module layered above it. Symbol lookups
7576 are now marginally more efficient (since the shadowed flag is no
7577 longer required) and symbol removal, such as on module unload, is
7578 considerably faster due to a reorganisation of the data structures
7581 * src/main.c (main): Don't mention `-H'.
7582 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
7585 * m4/hash.c: New generalised dynamic hash table data structure
7587 * m4/hash.h: Public interface.
7588 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
7589 (libm4_la_SOURCES): Add hash.c.
7590 * m4/symtab.c: More or less rewritten from scratch, within the
7591 bounds of the previous API.
7592 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
7593 call. Updated all callers.
7594 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
7595 declarations to reflect API changes.
7596 (M4INIT): Generate a declaration too, to avoid the warning with
7597 --enable-debug builds.
7600 * m4/utility.c (hash_table_size): Removed.
7601 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
7602 names, which are then looked up by builtin_dumpdef() as necessary.
7603 This implies a small speedup in builtin_symbols(), which discarded
7604 all of the symbol info under the old call.
7605 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
7606 shadowing is implicit in respect to the new data structures.
7607 symbol names are no longer duplicated here, they are stored in the
7608 key field of the hash table.
7609 Moved macro_args and blind_no_args...
7610 (m4_token_data): ...to here.
7611 m4/macro.c (expand_macro): Added a name argument since the symbol
7612 name is no longer copied into each struct m4_symbol. Modified all
7614 (collect_arguments): Ditto.
7615 * modules/m4.c (set_trace): Ditto.
7616 * modules/gnu.c (builtin_symbols): Updated.
7617 * src/freeze.c (produce_symbol_dump): Much improved in light of
7618 the improved symbol table layout.
7620 2001-09-01 Gary V. Vaughan <gary@gnu.org>
7622 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
7624 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
7625 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
7626 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
7627 SYMBOL_HANDLE): Ditto.
7628 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
7629 modules/gnu.c, modules/m4.c, src/freeze.c,
7630 src/main.c: Updated all references.
7632 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
7633 Automake 1.5 chokes on dynamic source file lists, Besides, it is
7634 already listed in m4_LDADD... how did that ever used to work?
7635 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
7637 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
7638 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
7640 * tests/m4: Don't call the m4 wrapper script with libtool, it
7641 works fine all by itself.
7643 2001-08-30 Gary V. Vaughan <gary@gnu.org>
7645 The experimental `changeword' feature never took off, and has
7646 no obvious advantages over `changesyntax' to compensate the
7647 enormous speed penalty it carries:
7648 * configure.in (ENABLE_CHANGEWORD): Removed.
7649 * m4/m4module.h (m4_set_word_regexp): Removed.
7650 * m4/m4private.h (m4_token_data): Removed original_text field.
7651 * m4/utility.c (m4_token_data_orig_text): Removed.
7652 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
7653 * m4/macro.c: Ditto.
7654 * src/main.c: Ditto.
7655 * modules/Makefile.am (changeword.la): Removed.
7656 * modules/changeword.c: File removed.
7657 * doc/m4.texinfo: References to changeword and --word-regexp
7659 * po/POTFILES.in: modules/changeword.c removed.
7660 * tests/atlocal.in (ENABLE_CHANGEWORD): Removed.
7661 * tests/builtins.at (changeword): Test removed.
7663 2001-08-30 Akim Demaille <akim@epita.fr>
7665 * bootstrap.sh: Create aclocal.m4 instead of modifying it.
7666 This also help having a single list of m4 files: in
7668 * config/Makefile.am (STANDARD_MACROS): Rename as...
7669 (ACLOCAL_MACROS): this.
7670 (list-standard-macros): Remove.
7673 2001-08-29 Gary V. Vaughan <gary@gnu.org>
7675 In an attempt to moderate my egomania...
7676 * tests/modules.at: Remove attributions.
7678 * tests/generate.awk: When making substitutions to "@&t@", either
7679 "&" or "\&" in the substitution string argument to gsub refer back
7680 to the matched text. "@\\&t@" seems to work though, Tests 43 and
7683 2001-08-29 Akim Demaille <akim@epita.fr>
7685 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)
7686 (include, indir, multiquotes, patsubst, pushdef/popdef, regexp)
7687 (sync-lines, trace, translit, undivert, wrap): Move to...
7688 * tests/builtins.at: this new file.
7689 * tests/others.at (Discard comments, import-environment): Move to...
7690 * tests/options.at: this new file.
7692 2001-08-29 Akim Demaille <akim@epita.fr>
7694 * tests/others.at (Freezing modules)
7695 (--module-directory: absolute path, modpath2, modpath3)
7696 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
7697 * tests/modules.at: here, new file.
7698 * tests/others.at, tests/generate.awk: Add a banner.
7699 * tests/testsuite.at: Adjust.
7700 (AT_CHECK_M4_FILTER): New, but unused.
7702 2001-08-29 Akim Demaille <akim@epita.fr>
7704 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
7706 * tests/others.at (wrap): Inline wrap.m4.
7707 (shadow): Inline shadow.m4.
7708 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
7709 * tests/m4: Simplify.
7711 2001-08-29 Akim Demaille <akim@epita.fr>
7713 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
7716 2001-08-29 Akim Demaille <akim@epita.fr>
7718 * tests/generate.awk (normalize): s/@__@/@&t@/.
7720 2001-08-28 Akim Demaille <akim@epita.fr>
7722 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.
7724 2001-08-28 Gary V. Vaughan <gary@gnu.org>
7726 * bootstrap (generate.awk): Generate test cases with new script.
7728 2001-08-27 Akim Demaille <akim@epita.fr>
7730 * tests/Makefile.am (installcheck-local): Don't use
7731 `dc_install_base' which is not visible here, but `exec_prefix'
7732 which is clearly the RT anyway.
7733 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
7734 related to testing a now installed m4.
7735 * tests/m4: Do it here.
7737 2001-08-27 Akim Demaille <akim@epita.fr>
7739 * tests/others.at (indir): Formatting change.
7741 2001-08-27 Akim Demaille <akim@epita.fr>
7743 * tests/Makefile.am (installcheck-local): New.
7744 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
7746 Prefer options over envvars.
7747 * src/main.c (main): First bug caught by the test suite (yeah!):
7748 --batch lacked a `break' which resulted in an accidental
7749 invocation of --discard-comments.
7751 2001-08-27 Akim Demaille <akim@epita.fr>
7753 * tests/others.at (capitalize, changeword, comments, ddivert)
7754 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
7755 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
7756 (sysv-args, trace, translit, undivert): Don't rely on files in
7757 examples/: AT_DATA them.
7759 2001-08-27 Akim Demaille <akim@epita.fr>
7761 Let the test suite use a wrapper around the not installed m4 to
7762 pretend it is (installed).
7764 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
7765 such a way that m4 does not process them.
7766 * configure.in: The package name seems to be `m4', not `M4'.
7768 * tests/atlocal.in (at_package, M4): Remove.
7769 * tests/testsuite.at, tests/others.at: Use m4, not $M4.
7771 2001-08-27 Akim Demaille <akim@epita.fr>
7773 * tests/Makefile.am (CLEANFILES): Remove.
7774 (DISTCLEANFILES, clean-local): New.
7775 * examples/mktests.sh: Remove.
7777 2001-08-27 Akim Demaille <akim@epita.fr>
7779 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
7780 Don't use aclocal: it's written by hand.
7781 * aclocal.m4: m4_include all the files instead of being built by
7783 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
7784 until it reads the traces by itself.
7785 * configure.in: Require Autoconf 2.42c as we are now using
7786 AC_CONFIG_TESTDIR instead of AT_CONFIG.
7787 Catch unexpanded `jm_' macros.
7788 * config/atconfig.m4: Remove.
7789 * config/error.m4: new.
7790 * config/Makefile.am: Ship the files included by aclocal.m4.
7791 * tests/Makefile.am (TESTSUITE_SOURCES): Rename as...
7792 (TESTSUITE_AT): this, to please Automake.

7803 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
7804 Robert Collins, building on Cygwin no longer requires Windows
7805 import and export symbol decorations.
7806 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.

7820 2001-08-20 Gary V. Vaughan <gary@gnu.org>
7822 Ansify the source. Previously we had a mix, where my code was
7823 in a K&R compatible style, and the preexisting code was in ANSI
7824 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
7825 and now the code base is much cleaner.

7828 VOID macro and all users.

7868 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
7869 * modules/m4.c (undivert): Disable the possibility of undiverting
7870 several files at once: it is not documented, it is inconsistent
7871 with the other macros, it can be straightforwardly mocked by
7872 several invocations, and most importantly, it prevents the
7873 possibility of other kinds of extension.
7874 Use `m4_numeric_arg'.
7876 2001-08-20 Akim Demaille <akim@epita.fr>
7878 * examples/include.m4: Typo.
7879 * tests/generate.awk: Really add it.
7880 * tests/Makefile.am: Adjust.
7881 * tests/others.at (Discard comments): It sure fails without `-c'.
7882 (include, undivert): Add -I examples/.
7884 2001-08-20 Akim Demaille <akim@epita.fr>
7886 Use sprintf, not ecft and friends since it is standard, portable,
7887 simplifies the code, and since the latter is even deprecated
7888 according to the GNU libc documentation.
7890 * modules/format.c: Drop evct support.
7892 2001-08-19 Gary V. Vaughan <gary@gnu.org>

8036 Drop Autoconf 2.13 compatibility.
8038 * configure.in (changeword): No need to undefine it, as anyway if
8039 it's defined, M4sugar moved it as m4_changeword.

8041 (m4_pattern_allow): As it exists in 2.50, just use it.
8042 (AC_OUTPUT): Split in AC_CONFIG_FILES and AC_CONFIG_COMMANDS.

8097 (M4FINISH_HANDLER): And similarly for finish functions.
8098 * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER
8099 -- Add indirection to the CONC macro so that arguments are
8101 * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
8102 * modules/shadow.c (m4_init_module): Ditto.

8114 instead of the old module argument.
8115 (m4_builtin_table_install): Ditto.
8116 * modules/load.c (m4_resident_module): Removed. This is no
8117 longer implemented as a magic symbol...

8135 various tokens that are passed between functions.
8136 (struct m4_symbol): Removed the module field. The
8137 module association does not belong with the symbol...
8138 * m4/input.c (struct m4_builtin): ...it belongs with the builtin

8157 (CDPATH) Neutralize.
8158 * tests/gethem: Use them.
8160 2001-08-14 Gary V. Vaughan <gary@gnu.org>

8177 shell variable m4_cv_func_obstack_h.
8178 * tests/defs (M4): Be more careful about relative path to libtool
8179 script and m4 binary by using $srcdir.

8182 optargs to the existing libltdl search path.

8191 interactive mode off.

8202 (M4_AC_FUNC_OBSTACK): Rename `m4_obstack' and `m4_obstack_h'.

8260 feature to mark modules as resident if they export
8261 `m4_resident_module' as TRUE.
8262 (m4_module_unload): Do not remove resident modules, and take care
8263 with symbol insertion and deletion with resident modules.

8276 * modules/gnu.c (builtin_functions): Make indir orthogonal to
8277 builtin, in that each is recognised as a macro only with parameters
8278 (builtin_indir): Passing 0 arguments is now an error, as with
8281 * src/main.c (usage): Added missing description of `-c' option.
8283 2000-11-29 Gary V. Vaughan <gary@gnu.org>
8285 Consolidate the myriad of dispersed test scripts into the
8286 tests subdirectory. I think I now have all the file where I
8287 want them, so there shouldn't be anymore upheaval =)O|

8328 Move the implementation of GMP support for the mpeval() builtin
8329 into a loadable module that depends on libgmp. mpeval() and
8330 eval() share a common parser, now in m4/evalparser.c; the code
8331 in m4/numb.c and m4/numb.h is now physically split between
8332 m4/eval.c (the eval() backend) and modules/mpeval.c (the
8333 mpeval() backend), rather than being differentiated by cpp
8334 macros and multiple inclusion. The mpeval module is always
8335 built but will generate an diagnostic if it is used from an
8336 installation that didn't link in the gmp library.
8337 * modules/Makefile.am: build and install the new mpeval module.
8338 * modules/mpeval.c: Now contains the former parts of m4/numb.c
8339 and m4/numb.h that are required for gmp support in mpeval().
8340 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
8341 * m4/evalmp.c: Removed.
8342 * m4/m4module.h: Removed conditional prototype for
8344 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
8345 and m4/numb.h that do not rely on gmp.
8346 * m4/evalparse.c: New file, contains the shared parts of the
8347 eval() and evalmp() parser implementations, and is no longer
8348 unencumbered by cpp magic to uncover the right parts.
8349 * m4/numb.h: Removed. It's former contents are split between
8350 m4/eval.c and modules/mpeval.c.
8353 * tests/other-tests/changeword.test: New test. Rudimentary
8354 testing of changeword builtin runs only if --wnable-changeword
8355 was used at configure time.
8356 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
8357 alternation correctly. Split into two expressions to compensate.
8358 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
8359 * modules/Makefile.am: Build changeword module.
8360 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
8361 only when --enable-changeword was passed to configure.
8362 (builtin_changeword): If --enable-changeword was not used, then
8363 report that changeword() builtin has no support in m4 binary.
8365 2000-11-28 Gary V. Vaughan <gary@gnu.org>
8367 * src/main.c (main): Fixed a particularly nasty bug is
8368 user_search_path setting -- the -M flag processing must be
8369 extremely careful with search path ordering, or else the default
8370 installed module directory (possibly containing modules from a
8371 previous release) is placed earlier in the search path than any -M
8372 arguments (which are relied upon to load uninstalled modules with
8373 most of the tests in the regresion suite).
8375 * modules/load.c (builtin_load): Nasty hack to prevent adding
8376 symbols to symtab again if a module is loaded more than once.
8377 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
8379 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
8380 possible NULL pointer dereference.
8382 * m4/module.c (m4_module_find_by_modname): Renamed from
8383 m4_module_modname_find. Fixed all references.
8384 (m4_module_find_by_builtin): New function.
8386 * modules/modfreeze.test: load the `load' module with each
8388 * src/freeze.c (produce_frozen_state): Simplified in light of
8389 module field in m4_symbol. Allow a third argument for text macros
8390 to name the originating module.
8391 (reload_frozen_state): ditto.
8392 * m4/m4module.h: Fixup prototypes.
8393 * m4/builtin.h (m4_builtin_define): Add a module argument so
8394 that symbols can be registered against the defining module.
8395 (m4_macro_define): ditto.
8396 * m4/m4private.h (m4_symbol): Make the module field const to save
8397 on casting in the rest of the code.
8398 (SYMBOL_MODULE): New macro.
8400 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
8401 symbol reference maintenance bugs when removing a symbol from the
8404 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
8406 2000-11-27 Gary V. Vaughan <gary@gnu.org>
8408 * configure.in (m4_cv_func_obstack): A better check for whether
8409 libc has an obstack implementation.
8410 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
8412 * configure.in (--with-modules): Changed semantics. This
8413 option is now used to list modules to be preopened.
8414 * src/m4.h: #include "ltdl.h" unconditionally.
8415 * src/main.c: Removed all dependencies on WITH_MODULES.
8416 * src/freeze.c: ditto.
8417 * modules/Makefile.am: ditto.
8418 * m4/m4.c (builtin_m4exit): ditto.
8419 * modules/modpath1.test: ditto.
8420 * modules/modpath2.test: ditto.
8421 * modules/modpath3.test: ditto.
8422 * modules/modpath4.test: ditto.
8423 * modules/modtest.test: ditto.
8424 * modules/shadow.test: ditto.
8425 * modules/unload.test: ditto.
8427 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
8428 comes up on demand in LTLIBOBJS now.
8429 * configure.in (getopt_long): Creating and relying on a link for
8430 getopt.h on hosts with no getopt_long() of thier own works
8431 correctly now. This is necessary so that callers of getopt_long()
8432 can simply `#include <getopt.h>': the naive way of doing this
8433 would end up using our own getopt.h and the installed
8434 getopt_long(), which is asking for trouble!
8435 (obstack_init): A similar argument applies to obstack.h and
8438 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
8439 On Solaris-2.5 (at least) the native dlopen implementation
8440 gets confused about m4.o when looking for module "m4". This
8441 version always looks for .la an .$lib_ext suffixed names first
8442 to work around the problem. Sigh.
8444 * po/POTFILES.in: Take account of these file movements.
8445 * src/Makefile.am (m4_SOURCES): removed eval.c.
8446 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
8447 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
8448 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
8449 * modules/m4.c (builtin_eval): Use m4_evaluate().
8450 * m4/eval.c: Moved here from src/eval.c to facilitate
8451 implementation of eval() builtin as part of the `m4' loadable
8453 (m4_evaluate): renamed from evaluate for namespace cleanliness.
8454 * m4/numb.c: Moved here from src/numb.c, since it is #included
8455 into eval.c at compile time.
8456 * m4/m4module.h (m4_evaluate): Added prototype.
8457 * src/m4.h (evaluate): Removed prototype.
8459 2000-11-25 Gary V. Vaughan <gary@gnu.org>
8461 * modules/perl.c (builtin_perleval): Use PL_na for
8462 compatibility with perl-5.6.
8464 * src/main.c (main): It is now safe to
8465 ``m4_module_install("m4")'', without tripping over the m4
8467 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
8468 versions having fixed the insidious module search order bug.
8470 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
8471 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
8473 * configure.in: Figure out whether to use the installed
8474 getopt.h or the supplied one.
8475 * src/Makefile.am: ditto.
8477 * po/POTFILES.in: List files in their new positions.
8479 * config/ltmain.sh: This needs to be checked in to match the
8480 libtool macros copied to acinclude.m4 (until a released
8481 libtool copes with m4's needs).
8482 * bootstrap: Run gettextize.
8484 2000-11-24 Gary V. Vaughan <gary@gnu.org>
8486 * AUTHORS: Added my details.
8489 * bootstrap: temporary update until released libtool catches up.
8491 * All files: Use new GNU GPL copyright blurb with current contact

8525 * modules/gnu.c: New file implementing a new loadable module wuth
8526 definitions for all the gnu extension builtins.
8527 * modules/format.c: Moved here from src/format.c. Now included
8530 * src/main.c (main): Load the traditional module if m4 was
8531 started in `no_gnu_extensions' mode.
8532 * modules/traditional.c: New file implementing the ``unix'' macro,
8533 required when m4 is executed in traditional mode, as a loadable
8536 * src/main.c: Renamed from m4.c to avoid confusion with
8538 (main): Always load the m4 module.
8539 * modules/m4.c: New file implementing a new loadable module with
8540 definitions for all m4 builtins that are not gnu extensions.

8551 * m4/symtab.c: ditto.
8552 * m4/debug.c: ditto.

8554 * m4/output.c: ditto.
8556 * m4/ltdl.h, m4/ltdl.c: ditto.
8557 * m4/utility.c: Odd functions moved here from files in the src
8558 directory to facilitate builtin migration.
8560 2000-08-12 Gary V. Vaughan <gary@gnu.org>
8562 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
8563 error message, to make translators' jobs a little easier.
8564 (builtin_builtin): ditto.
8565 (builtin_traceon): ditto.
8566 (builtin_traceoff): ditto.
8567 Reported by Akim Demaille <akim@epita.fr>
8569 * m4/Makefile.am (pkgincdir): Deleted. Use automake's built in
8570 pkgincludedir instead.

8593 makeinfo calculates them for us, and to make any future
8594 reorganisation easier.
8595 (Frozen files): Document format version 2.
8596 `V' now takes argument `2'.
8597 `F' can take a single argument if symbol and builtin names
8598 are the same, or 3 arguments if the builtin is from a module.
8599 New `S' specification for saving syntax table contents.
8600 New `M' specification for saving loaded module names.

8736 * src/m4.c (main): Assume interactive mode if STDIN is connected

8739 initialised from here when loading a frozen file.
8741 * src/builtin.c: Much improved macro definition style.
8742 * src/m4private.h: Internal structures for m4_builtin and

8754 odule defines an identical name.
8755 * src/symtab.c (remove_table_reference_symbols): remove all symbol
8756 table entries which refer to a given builtin table.

8785 * README: Caveat about nls not supported by dll architecture on
8788 * TODO (MODULE SPECIFIC ISSUES): more ideas for the future.
8790 * tests/Makefile.am (stamp-TESTS): now works with VPATH.
8791 * src/Makefile.am (m4_LDADD): use $(builddir) for VPATH.
8792 * modules/Makefile.am (LIBS): ditto.
8793 (INCLUDES): search $(top_srcdir) (for eg. <m4/error.h>) and then
8794 $(top_srcdir)/m4 (for only <m4module.h>).

8802 * modules/time.test: Removed due to timezone dependence,
8803 * modules/Makefile.am (TESTS): Removed time.test.
8805 * configure.in: Use $3 of AC_DEFINE so that we can,,,
8806 * acconfig.h: Remove everything except the gettext parameters.
8807 * acm4/gmp.m4: Add a serial number, and take advantage of $3 of
8809 * acm4/ltdl.m4: Updated to latest from libtool cvs.
8810 * acm4/modules.m4: Remove code which duplicates ltdl.m4 and
8811 increment serial number.
8813 * Makefile.am (SUBDIRS): Moved @MODULES_DIR@ to compile before
8814 src dir and immediately after libm4 is built for confidence that
8815 it doesn't rely on the src directory.
8816 (SUBDIRS): Moved doc dir to the end since helptoman.pl and
8817 makeinfo stop the build on cygwin (because they don't work).
8819 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
8821 * m4/m4private.h: ...is not a public header, so moved to src.
8822 Add `#include <config.h>', `#define _COMPILING_M4' and
8824 * m4/Makefile.am (noinst_HEADERS): remove m4private.h.
8825 * src/Makefile.am (noinst_HEADERS): add m4private.h.
8826 * src/builtin.c: `#include "m4private.h"' now takes care of the
8827 above. Duplicates removed.
8828 * src/debug.c: ditto.
8829 * src/eval.c: ditto.
8830 * src/evalmp.c: ditto.

8844 * m4/Makefile.am (CLEANFILES): @EXEEXT@ left libtool wrapper behind.
8845 (INCLUDES): Look first in $(top_srcdir) (for eg. <m4/error.h>),
8846 and then in $(top_srcdir)/lib (for eg. "m4private.h").
8847 * src/Makefile.am (m4_LDADD): replace libi/libm4.la with
8849 * m4/m4error.h: Renamed error.h, for installation to
8850 $prefix/include/m4..
8851 * m4/m4obstack.h: Renamed obstack.h, for same reason.
8852 * m4/m4regex.h: Renamed regex.h, for same reason.
8853 * m4/m4error.c: Renamed error.c, and use #include "error.h".

8865 From Akim Demaille <akim@epita.fr>
8867 2000-01-17 Gary V. Vaughan <gary@gnu.org>
8869 * src/ltdl.c: Use access() to abort doomed module load attempts
8870 if module file does not exist.
8872 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
8873 getopt1.o will already be used if appropriate, so I moved getopt.c
8874 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
8876 * modules/modpath1.test: Use correct filename in header line.
8877 * modules/modpath2.test: ditto.
8878 * modules/modpath3.test: ditto.
8879 * modules/modpath4.test: ditto.
8881 Without these changes lt_dlopen("test") attempts to
8882 LoadLibrary("/bin/test") on Windows, which although harmless
8883 generates a spurious error message which spoils most of the tests:
8884 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
8885 (TESTS): s/test.test /modtest.test /
8886 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /
8887 (test_la_SOURCES, test_la_LDFLAGS): renamed to use modtest.
8888 * modules/modpath1.test: s/test.m4 /modtest.m4 /
8889 * modules/modpath2.test: ditto.
8890 * modules/modpath4.test: ditto.
8891 * modules/modpath3.test: s/-m test /-m modtest /
8892 * modules/shadow.m4: use {un,}loadmodule(`modtest').
8894 2000-01-16 Gary V. Vaughan <gary@gnu.org>
8896 * src/ltdl.c (find_file): Updated to new version with fixed memory
8897 allocation bug in `next'.
8898 * src/ltdl.h: updated to match.
8900 * modules/Makefile.am: Cleaned up and reordered.
8902 2000-01-16 René Seindal <rene@seindal.dk>
8904 * modules/Makefile.am (TESTS): New tests for the module system.
8906 * modules/*.test: New files.
8908 * src/m4.c (main): Added call to module_init().
8909 Treats -M and -m as the arguments -D -U and -t, ie deferred.
8911 * src/m4.h: Added declaration of module_init().
8913 * src/module.c (module_init): No longer static
8915 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
8916 Added to shut up automake about non standard libtool library
8919 * src/module.c: Disabled DEBUG by default.
8921 * modules/README: Changed example from unload.m4 to shadow.m4
8923 * modules/shadow.m4: Renamed from unload.m4

8930 2000-01-12 Gary V. Vaughan <gary@gnu.org>
8932 * doc/help2man.pl: updated to version 1.020.
8934 * lib/COPYING.LIB: updated to version 2.1.
8936 * lib/m4module.h: restructure the M4_SCOPE code to work when
8937 creating a dll which links with libm4.la and both DLL_EXPORT
8938 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
8941 2000-01-11 Gary V. Vaughan <gary@gnu.org>
8943 Merged the following changes from my tree:
8945 1999-06-15 Gary V. Vaughan <gary@gnu.org>
8947 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
8948 ported to compile shared libs.
8950 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
8951 use `__declspec(dllimport)' when linking libm4.la on win32.
8952 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
8954 * configure.in (M4OBJS): Discover whether we need the shipped
8955 implementation of getopt_long.
8956 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
8957 main binary here, as opposed to the module library in lib/libm4.la.
8959 1999-06-14 Gary V. Vaughan <gary@gnu.org>
8961 * modules/README: Updated to describe the improved libltdl based
8963 * README (cygwin): Added some compilation notes for building m4
8964 correctly under cygwin.
8965 * TODO: Cleaned out the entries for the module system since they
8966 are now implemented.
8968 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
8969 all instances of __P with M4_PARAMS.
8971 * lib/getdate.h: removed unreferenced file.
8973 * lib/m4private.h: New file to define the private interface to the
8974 token_data struct, which must be shared between m4module.c, and
8975 builtin.c but not exported to modules built from the installed
8976 m4module.h since it's size changes depending on compile time
8979 * src/m4.h: Lots of stuff moved to lib/m4module.h.
8981 * lib/m4module.h: New file to define the interface available when
8982 compiling m4 modules.
8983 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
8984 necessary for module compilation into this new file.
8986 * lib/Makefile.am (include_HEADERS): install headers (renamed to
8987 avoid nameclash with other system headers) necessary for compiling
8989 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
8990 so that modules can include the (renamed) installed headers and
8991 be guaranteed a matching implementation.
8992 * lib/m4error.h: renamed from error.h.
8993 * lib/m4obstack.h: renamed from obstack.h.
8994 * lib/m4regex.h: renamed from regex.h.
8995 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
8996 implementation, simply include the shipped version
8997 unconditionally, otherwise it is hard for a module to know
8998 whether the m4obstack.h header it is using matches the
8999 implementation it ends up linking against.
9000 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
9003 1999-05-18 Gary V. Vaughan <gary@gnu.org>
9005 * examples/misc.test: Don't run this test on machines which don't
9006 have a root user in /etc/passwd (e.g. cygwin).
9008 * tests/get-them (/^@example$/): Error messages might have a
9009 ``.exe'' suffix to the program name, or else use the libtool
9010 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
9011 of these cases are now catered for when comparing error messages
9013 * tests/other-tests/*.test: ditto.
9014 * examples/*.test: ditto.
9016 * tests/defs (M4): use libtool execute mode.
9017 * examples/defs (M4): ditto.
9019 * tests/get-them (END): explicitly close any open file.
9020 (printthem): In a regular expression, '{' is the start of a repeat
9021 count! Use `[{]' for a literal open brace.
9022 (/^@node /): Don't use substr on a string shorter than the trim
9025 1999-05-17 Gary V. Vaughan <gary@gnu.org>
9027 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
9029 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
9031 2000-01-10 Andreas Schwab <schwab@suse.de>
9033 * tests/other-tests/gmp.test: Find config.sh in build directory.
9035 * configure.in: Find tests/mkconfig.sh in $srcdir.
9037 * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in
9038 <signal.h> (for SUS2 compliant systems).
9040 * src/stackovf.c: Check for HAVE_SIGINFO_T in addition to
9043 2000-01-10 René Seindal <rene@seindal.dk>
9047 * TODO, NEWS: Cleaned up and updated.
9049 * src/m4.c (main): New variable exit_status for exit status in
9050 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
9051 file cannot be read instead of EXIT_SUCCESS.
9053 * src/builtin.c (m4_indir): Changed error message to help
9054 translators (from Akim Demaille <demaille@inf.enst.fr>).
9056 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
9059 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
9062 * src/input.c (match_input): Reordering of code, to avoid multiple
9063 calls to push_string_init() from obstack_grow(), which can happen
9064 with some compilers (found and fixed by James Bonfield
9065 <jkb@mrc-lmb.cam.ac.uk>).
9067 * src/stackovf.c: Added prototypes for ultrix.
9068 (setup_stackovf_trap): Added __P to cast.
9069 (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>)
9071 2000-01-09 René Seindal <rene@seindal.dk>
9073 * doc/m4.texinfo (Changequote): Added comment about changing
9074 quotes when the old quote is a part of the new.
9076 * src/builtin.c (expand_ranges): Added break after trailing dash.
9077 This caused misbehavious on some systems (found and fixed by Akim
9078 Demaille <demaille@inf.enst.fr>).
9080 * AUTHORS: Thomas Tanner included
9082 * acconfig.h: Added entry for ss_sp (see below).
9084 * configure.in (use_stackovf): Added check for stack_t with member
9085 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert
9086 <eggert@twinsun.com>).
9088 * doc/m4.texinfo (Frozen files): Added a simpler example for
9089 generating frozen files from several input files.
9091 1999-11-14 Paul Eggert <eggert@twinsun.com>
9093 * po/POTFILES.in: Add lib/getopt.c, lib/obstack.c,
9094 lib/regex.c, lib/xmalloc.c.
9096 1999-11-10 René Seindal <rene@seindal.dk>
9098 * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal.
9100 * src/module.c: reindented.
9101 (module_load): return if this is a repeated load of same module.
9102 (module_init): slight change of logic to avoid repeated
9103 initialisation debug messages.
9105 * Makefile.am (DIST_SUBDIRS): Added to ensure modules/ is included
9106 in the distribution.
9108 * modules/Makefile.am (test_la_LDFLAGS): set to -module to silence
9109 automake warnings about missing lib prefix.
9110 (time_la_LDFLAGS): ditto
9111 (stdlib_la_LDFLAGS): ditto
9113 1999-11-10 Paul Eggert <eggert@twinsun.com>
9115 * src/m4.h: Include error.h, since our macros use error.
9116 * src/m4.c: Don't need to include error.h.
9118 1999-11-09 Paul Eggert <eggert@twinsun.com>
9120 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
9121 and zero, as Solaris 7 cc does.
9122 (bcopy): Remove macro; no longer needed with new obstack.h.
9124 * src/output.c (freeze_diversions): Don't assume that a
9125 diversion size can fit in `int'. Check for diversion file
9126 size too large to be printed with `unsigned long'.
9128 * src/Makefile.am (CFLAGS): Omit -Wall.
9130 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.
9132 * src/debug.c (trace_format):
9133 Use ANSI C if (defined __STDC__ && __STDC__) || defined PROTOTYPES.
9135 * src/freeze.c (produce_frozen_state):
9136 Don't assume string lengths fit in int.

9155 1999-03-30 Gary V. Vaughan <gary@gnu.org>
9157 * src/builtin.c: moved module loading functions into...
9158 * src/module.c: entirely new implementation using libltdl.
9159 * po/POTFILES.in: added src/module.c.
9160 * modules/Makefile.am (LTLIBRARIES): Removed lib prefix as these
9161 are modules, not linktime libraries.
9162 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
9163 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
9164 avoidance on exported symbols.
9165 * modules/test.c (m4_macro_table, m4_init_module,
9166 m4_finish_module): ditto.
9167 * modules/time.c (m4_macro_table): ditto.
9169 * modules/time2.m4: new file which requires command line loading
9171 * src/m4.c (--load-module): dynamically load named runtime module
9172 into running executable before reading the source.
9173 (--module-directory): prepend a directory to the module search
9175 (module_init()): Do this the first time we load a module instead;
9176 if the module subsystem is broken normal m4 scripts can still run.
9177 * src/m4.h (install_builtin_table): is now exported.
9179 1999-03-26 Gary V. Vaughan <gary@gnu.org>
9181 * src/module.c: removed. No longer required.

9192 * src/Makefile.am (MAINTAINERCLEANFILES): ditto.
9193 * tests/Makefile.am (MAINTAINERCLEANFILES): ditto.
9195 * acinclude.m4: removed. `aclocal -I acm4' handles this much
9197 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
9198 * acm4/gettext.m4: removed. It causes a multiple definition vs.
9199 the installed gettext.m4 file when running aclocal.
9201 1999-03-25 Gary V. Vaughan <gary@gnu.org>
9203 * configure.in (AM_INIT_AUTOMAKE): bumped version number to
9204 distinguish this from the last prerelease.
9205 (AC_LIBLTDL_CONVENIENCE): build libltdl as a convenience library
9206 in its own subdirectory.
9208 * modules/Makefile.am (*_SOURCES): renamed to use libtool's "no
9209 lib prefix on a module" feature.
9210 (LDFLAGS): Added `-module -avoid-version' flags to build
9211 versionless module libraries.
9212 * src/builtin.c (m4_load_module): use libltdl.
9213 (module_unload_all): use libltdl.
9214 * src/m4.c (module_init): initialise module loading on demand for
9215 better diagnostics, and so that m4 will still work even if
9216 the module code is broken.
9217 * src/m4.h (module_init): removed. No longer relevant.
9218 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on
9219 exported symbols for compatibility with dlpreopening.
9220 * modules/test.c (m4_macro_table, m4_init_module,
9221 m4_finish_module): ditto.
9222 * modules/time.c (m4_macro_table): ditto.
9224 * bootstrap: New file. Runs all the autoutils in the right order
9225 after a fresh checkout, or a make maintainer-clean.
9227 1999-02-18 Akim Demaille <demaille@inf.enst.fr>
9229 * src/builtin.c (dump_symbols): New function, factoring common
9230 content of m4_dumpdef and m4_symbols.
9231 (m4_dumpdef): Use it.
9232 (m4_symbols): New function, implementing `symbols'. Use it.
9233 * doc/m4.texinfo: Fixed missing commas after @xref, so that the
9234 file compile with modern makeinfo.
9235 (Symbols): New node, documenting symbols.
9236 (direntry): Modernize.
9238 1998-12-11 René Seindal <rene@seindal.dk>
9240 * src/builtin.c (predefined_tab): New predefined macros
9241 __m4_changeword__, __m4_gmp__ and __m4_modules__ for testing for
9242 configure time options.
9244 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
9246 * src/module.c (module_try_load): Don't try to be clever and
9247 overwrite argument string. Instead allocate all constructed
9248 strings locally, since they can have arbitrary lengths. Make
9249 arguments pointers to const.
9250 (module_search): Simplify due to above change.
9252 1998-11-29 René Seindal <rene@seindal.dk>
9256 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): New tests.
9258 * tests/other-tests/import-environment.{m4,test}: New test.

9262 * doc/m4.texinfo (Invoking m4): Updated for --discard-comments.
9264 * src/m4.c (main): New option -c --discard-comments.
9265 New global variable discard_comments.
9267 * src/m4.h (token_type): New TOKEN_NONE for tokens to be
9268 discarded, ie never returned from next_token().
9269 Added declaration of discard_comments.
9271 * src/input.c (next_token): Now loops until token type is not
9272 TOKEN_NONE. Comments are now given this type when comments should
9275 * doc/m4.texinfo (Invoking m4): Updated for --import-environment
9278 1998-11-28 René Seindal <rene@seindal.dk>
9280 * src/m4.c (main): New option --import-environment (no single
9283 * When configured with --with-gmp both the normal (fast) eval()
9284 and the gmp aware mpeval() are defined. To restore previous
9285 bahaviour use "define(`eval', defn(`mpeval'))".
9287 * tests/other-tests/gmp.m4: Changed to use mpeval().
9289 * src/evalmp.c: New file for compiling eval.c as gmp aware.
9290 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
9292 * src/eval.c: Now includes "numb.c" directly. Everything in this
9293 file must by static, except evaluate(), which is changed to
9294 mp_evaluate() if USE_GMP in force.
9296 * src/numb.c: Changed to be included by eval.c instead of being
9297 compiled separately. Everything is declared static.
9299 * src/numb.h: Removed declarations of functions, as numb.c is now
9302 * src/builtin.c: Declaration of m4_mpeval() added.
9303 Inserted `mpeval' in builtin table.
9304 (do_eval): New function with common code for m4_eval and m4_mpeval.
9305 (m4_mpeval): New function for gmp version of eval.
9307 * src/m4.h: Declaration of mp_evaluate().
9309 * src/Makefile.am (m4_SOUCES): Includes mpeval.c.
9310 (EXTRA_m4_SOURCES): Now has numb.c and numb.h
9312 * src/m4.c (main): m4 --version also shows which options were used
9313 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
9315 1998-11-27 René Seindal <rene@seindal.dk>
9317 * Error messages now always print program name before input file
9318 name as specified by GNU coding standards. Reported by Akim
9319 Demaille <demaille@inf.enst.fr>.
9321 * doc/m4.texinfo (Include): Change due to changed error message
9325 * tests/get-them: Minor change to sed script due to changed error
9328 * src/m4.c (print_program_name): New func used to print program
9329 name, input file and line number in error (). Used as an
9330 error_print_progname handler.
9331 (reference_error): Removed.
9332 (main): Assigns error_print_progname.
9334 * src/m4.h (M4ERROR): Removed reference_error ().
9336 1998-11-25 René Seindal <rene@seindal.dk>
9338 * Updated to libtool 1.2b.
9340 * src/builtin.c (install_builtin_table): Added braces to avoid
9341 warning of ambiguous 'else'.
9343 * src/module.c: Inserted search path code from path.c modified to
9345 (module_init): Configured default path used only if M4MODPATH is
9347 (module_try_load): Now reads libMODULE.la as generated by libtool
9348 for actual module name.
9349 (module_load): Gives better error messages on failure.
9351 * src/m4.h: Added declarations of structures and functions for
9352 generic search path handling.
9354 * src/path.c: Removed all module specific code and introduced new
9355 functions of more generic search path handling.
9357 1998-11-24 René Seindal <rene@seindal.dk>
9359 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
9360 included gettext, as <libintl.h> might not be found
9361 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
9363 1998-11-22 René Seindal <rene@seindal.dk>
9365 * src/output.c (insert_diversion): Fixed bug that might cause m4
9366 to read from standard output! Triggered by input
9367 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
9368 so now 'undivert(0)' does nothing.
9370 1998-11-18 René Seindal <rene@seindal.dk>
9374 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
9375 could be changed when compiling a illegal regexp, causing later
9376 use of the regexp to dump core.
9378 * src/module.c (module_load): Changed error message to conform to
9381 * src/m4.c (usage): Added message about reporting bugs.
9383 * doc/m4.texinfo (Changeword): Corrected a wrong example.
9384 (Changeword): Added note about the type of regexps used.
9386 * ltconfig, ltmain.sh: New files from Libtool 1.2.

9391 * acm4/modules.m4 (AM_WITH_MODULES): Redone completely to work
9394 * modules/Makefile.am: Changed completely to compile modules using
9395 libtool. The modules are compiled as shared libraries, and are
9396 renamed when installed.
9398 * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
9399 USE_SHL_LOAD to HAVE_SHL_LOAD
9401 * src/builtin.c (shipout_string): Now tests for a NULL string.
9403 * src/module.c: New level of indirection around non-portable
9404 functions to load shared objects. Intended to encapsulate the non
9405 portable parts better and to reduce the number of #ifdefs in the
9408 * Makefile.am (DIST_SUBDIRS): Instead of EXTRA_DIST for added
9409 directory modules/ to the distribution.
9411 1998-11-15 René Seindal <rene@seindal.dk>

9416 functions: getcwd, getlogin, getpid, getppid, getuid, getpwnam,
9417 getpwuid, hostname, rand, srand, getenv, setenv, unsetenv, uname.
9419 * src/builtin.c (shipout_string): New convenience function for
9420 builtins and modules.
9422 * src/module.c (module_load): Tentative support for
9423 shl_load/shl_findsym, but I cannot test it. Copied from MetaHTML.
9425 * Makefile.am (SUBDIRS): Directory modules added if configured.
9427 * modules/Makefile.am: Now correctly compiles and installs
9428 modules in pkglibexecdir.

9431 These two are now initialised by autoconf macros.
9433 * src/path.c (module_env_init): MODULE_PATH is always on the
9436 * src/Makefile.am: Now generated pathconf.h which defined the
9437 default MODULE_PATH.
9439 * configure.in (pkglibexecdir): Added defintion of pkglibexecdir,
9440 where modules are installed.
9442 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
9443 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
9444 build and install automatically, and it is prepared for other
9445 interfacec than dlopen().
9447 * src/builtin.c (predefined_tab): Added __m4_version__ for the
9448 current version of GNU m4. It is a GNU extension.
9450 1998-11-14 René Seindal <rene@seindal.dk>

9480 * tests/Makefile.am (GENERATED_TESTS): Renamed gentest to
9483 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): Added manually
9484 maintained tests in tests/other-tests. These currently tests for
9485 8-bit transparency, multiple precision arithmetic and sync-line
9486 output. Test for stackoverflow detection does not work.
9488 * examples/Makefile.am (TESTS): Added tests for all example files.
9490 * examples/mktests.sh: New file. Help program for creating test
9493 * tests/mkconfig.sh: New file to generate tests/config.m4 and

9524 * doc/m4.texinfo (Format): Documented that format is blind.
9526 * src/builtin.c (builtin_tab): Builtin format marked as blind.
9528 1998-10-07 René Seindal <rene@seindal.dk>
9532 * tests/Makefile.am (GENERATED_TESTS): Changed .m4 extension to
9533 .test, as the files are no longer just m4 input.
9535 * tests/get-them (FILE): Changed .m4 extension to .test.
9537 * src/m4.h (token_type): New token type TOKEN_SPACE introduced.
9538 Otherwise quoted strings with leading whitespace first in a macro
9539 argument would be eliminated.
9541 * src/macro.c (expand_token): Handles new token type TOKEN_SPACE.
9542 (expand_argument): Do.
9544 * src/input.c (next_token): SPACE and NUM/OTHER characters are only

9546 character. Otherwise they might include a comment/quote leader.
9547 (next_token): Returns new token type TOKEN_SPACE.
9549 * src/builtin.c (push_builtin_table): New function to push a
9550 builtin_table on the stack without installing its contents.
9551 (find_builtin_by_name): Added call to push_builtin_table() if
9552 reading frozen files. Otherwise the builtins named in the frozen
9553 files could not be found.

9562 1998-10-04 René Seindal <rene@seindal.dk>
9566 * configure.in (ALL_LINGUAS): Added Polish pl.po
9568 1998-10-03 René Seindal <rene@seindal.dk>

9578 * src/builtin.h: New file, declares some functions from builtin.c
9579 that are of use for other modules (shipout_int, numeric_arg,
9580 skip_space, bad_argc), and the macros ARG() and DECLARE().
9582 * src/builtin.c (install_builtin_table): New function. Each
9583 module brings in a builtin_table, which is pushed on a stack.
9584 (struct builtin_table): New struct for list of builtin_tables.
9585 (m4_loadmodule): New function to implement builtin "loadmodule".
9586 (shipout_int): No longer static, to be used by modules.

9607 * configure.in: Added modules/Makefile to AC_OUTPUT.
9609 * configure.in: Added code to implement --with-modules. Tests for
9612 * acconfig.h: Added WITH_MODULES
9614 1998-10-02 René Seindal <rene@seindal.dk>
9616 * examples/Makefile.am (pkgdata_DATA): Removed special target for
9617 check and variables TESTS. These tests are now run from the
9620 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
9621 directory. The files stay there but the tests are run from the
9624 * tests/Makefile.am (EXTRA_DIST): Added run-test.
9626 * tests/run-test: New file. Run a test manually
9628 * tests/Makefile.am, tests/get_them: Moved automatically generated
9629 tests (from the manual) to sub directory tests/gentest/. The
9630 tests/ directory had gotten a bit messy.
9632 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
9634 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\
9635 wrap}.test: Added a few testcases.
9637 1998-08-21 Erick Branderhorst <Erick.Branderhorst@asml.nl>

9643 * configure.in (jm_WITH_REGEX, jm_PREREQ_ERROR):
9644 acm4/{error,regex}.m4 (from fileutils-3.16u.tar.gz).
9646 * acm4/Makefile.am: created providing rules to create
9647 $(top_srcdir)/acinclude.m4 to be used by aclocal.
9649 * tests/defs (LANGUAGE, LC_ALL, LANG): force them to be
9650 `C'. Reported by Ulrich Drepper.
9652 * Makefile.am (SUBDIRS): Removed checks directory
9653 * configure.in (AC_OUTPUT): Removed checks/Makefile
9655 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
9656 the space when m4.texinfo is edited and whitespace.el is active.
9657 (Defn,example): idem.
9659 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
9661 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
9662 ../COPYING. ../Makefile is a file which is certainly present when
9663 test is executed in testSubDir. One can't be sure that the COPYING
9664 file is in .. or ../.. in all situations, the ../Makefile is
9667 * doc/m4.texinfo (Include): adjusted expected test output
9668 according to new tests, i.e. the input will always come from the
9669 file `in' created by the test.
9671 * tests/Makefile.am: Added three lines at the top to get
9672 esyscmd.1.test working.
9674 * tests/get-them: modified to generate clearer tests who will need
9675 less maintenance when new test examples are created in
9676 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
9677 need the generic file `defs') shell scripts creating `in', `ok',
9678 `out' and when apropriate `okerr' and `err' in the directory
9679 `testSubDir' when executed. The compare of `ok' and `out'
9680 (and of `okerr' and `err') will be the exit status of the test.
9681 `out' must match `ok' (and `okerr' must match `err') for the test
9684 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
9685 the tests generated by tests/get-them getting it input normally
9686 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
9687 (dot) before the numeric part) is reserved for all other (hand
9688 written) tests. The `+' means one or more times.
9690 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
9692 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
9693 supported short man page to refer to info documentation
9694 * helptoman.pl: added
9695 * configure.in: AC_PATH_PROG(PERL,perl)
9696 * Makefile.am (SUBDIRS): doc after src
9698 * libitized with libit 0.5 from
9699 ftp://ftp.iro.umontreal.ca/pub/contrib/pinard/maintenance/libit.
9701 * configure.in (AC_REPLACE_FUNCS): added xmalloc xstrdup
9702 * lib/Makefile.am (libm4_a_SOURCES): removed automakely supported

9719 * src/builtin.c (m4_changesyntax): Added builtin macro
9720 "changesyntax" to modify the syntax table.
9722 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax
9723 table. All categories are assigned a syntax code and tokens are
9724 read according to this table.
9726 1998-08-09 René Seindal <rene@seindal.dk>
9728 * src/numb.{c,h}: New files, implements multiple precision eval
9729 using GNU gmp. Originally submitted by John Gerard Makecki
9730 (johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.
9732 * doc/m4.texinfo (Eval): Added documentation for multiple
9733 precision arithmetic library support.
9735 * src/m4.{c,h}, src/eval.c, src/builtin.c, configure.in: Changes
9736 to accommodate multiple precision eval.
9738 1998-08-07 René Seindal <rene@seindal.dk>
9740 * src/input.c (MATCH, match_input), src/m4.h: changed definition
9741 of comment and quote strings to `unsigned int' to allow eight bit
9742 chars (reported by andrewb@zip.com.au (Andrew Bettison)).
9744 * src/builtin.c, doc/m4.texinfo: Builtin `syncoutput' added by
9745 patch from Mike Howard <mike@clove.com>
9747 1998-08-06 René Seindal <rene@seindal.dk>
9749 * gettext.m4: corrected AM_WITH_NLS to handle use of installed
9752 1998-08-03 René Seindal <rene@seindal.dk>
9756 * src/m4.h: Added ifdef ENABLE_NLS around include of <libintl.h>
9757 and _ macro. M4 now builds with --disable-nls.
9759 * src/m4.c (main): reintroduced textdomain(PACKAGE) to get gettext
9760 to look for right message catalogs. Call indef'ed by ENABLE_NLS.
9762 * configure.in (ALL_LINGUAS): Added complete list of translations:
9763 de fr it ja nl ru sv.
9765 1998-05-23 Erick Branderhorst <Erick.Branderhorst@asml.nl>
9767 * po/nl.po: Dutch translation by Erick Branderhorst.
9769 * po/fr.po: French translation by Erick Branderhorst, based on the
9770 translations by François Pinard in fr.msg and m4.cod.
9772 1998-05-22 Erick Branderhorst <Erick.Branderhorst@asml.nl>
9776 * src/m4.c: #include <signal.h> not <sys/signal.h>.
9778 * src/Makefile.am: CFLAGS = -Wall @CFLAGS@.
9780 * checks/Makefile.am: explicit list tests in CHECKS.
9782 * configure.in, {,src,doc,lib,examples,checks}/Makefile.am,

9784 mkinstalldirs, install-sh: Added automake (1.3) support.
9786 * lib/{alloca.c,error.{c,h},get{date.h,opt.{c,h},opt1.c},
9787 obstack.{c,h},regex.{c,h},strtol.c,xmalloc.c,xstrdup.c}:
9788 Used libitize (0.4) to update.
9790 * configure.in, ABOUT-NLS, intl/*, po/*: Added gettextize
9791 (0.10.25) support. Removed LOCALE, fr.msg, m4.cod and adjusted
9794 * src/stackovf.c: #ifdef USE_STACKOVF ... #endif to (de-)activate

9842 be opened, return immediately after producing the error message.
9843 Reported by Andreas Schwab.

9846 ANSIfying compiler flags, this is of no use to check it before.
9847 Reported by Alexander Lehmann.
9849 1994-11-01 François Pinard <pinard@iro.umontreal.ca>
9851 * src/macro.c (collect_arguments): Cast obstack arguments to
9852 (voidstar), so avoiding compiler warnings.
9853 Reported by Joseph E. Sacco.
9855 * src/freeze.c (produce_frozen_state): Cast printed lengths to

9874 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
9875 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
9876 defines __STDC__ to 0, for indicating it is *not* ANSI!
9877 Reported by Kaveh R. Ghazi.

9895 Remove the sed filter after ansi2knr for debug.c. Use $O instead
9896 of $U, put underline in extensions rather than in basenames. Use
9897 implicit rules, now that regularity makes this possible.
9898 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
9899 of ansi2knr whenever it is needed.
9900 * configure.in: Adjusted for correct STACKOVF substitution.
9901 * src/debug.c (trace_format): When not __STDC__, use (...) as a
9902 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.
9903 Reported by David MacKenzie.
9905 * Makefile.in: Remove binprefix. Use transform_name instead.
9906 Reported by David MacKenzie.
9908 * doc/Makefile.in: Create version.texi, use it, clean it.

9913 * Makefile.in (all, install, uninstall): Depend on Makefile.
9915 * Makefile.in: For actions invoking $(MAKE) from within compound
9916 sh statements, exit non-zero if the sub-make fails. Otherwise,
9917 the top-level make may exit successfully when it should fail.
9918 Reported by Jim Kingdon.
9920 * {,/*}Makefile.in: Use && after all cd, in case they fail.
9922 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

9965 Reported by Karl Berry.
9967 1994-09-14 François Pinard <pinard@iro.umontreal.ca>
9969 * lib/Makefile.in (mostlyclean): Added.
9970 (TAGS): Make in $(srcdir).
9972 * configure.in: Use `choke me' in test, like everywhere!
9974 * {doc,examples,lib,src}/Makefile.in (check): Deleted, as
9975 unreacheable and useless.
9977 * doc/Makefile.in (texclean): Deleted, merged in mostlyclean.
9979 * lib/Makefile.in (DISTFILES): Distribute TAGS.
9980 (distclean): Do not remove TAGS.
9981 (realclean): Remove it.
9982 * Makefile.in: Make TAGS in lib also, not just in src.
9983 Reported by Karl Berry.
9985 * Makefile.in (distclean, realclean): Instead of recursively
9986 calling $(MAKE) for the -local part, allow parallel execution of
9987 -recursive and -local, only delay the removal of config.status,
9988 which is repeated in both goals.
9990 1994-09-13 François Pinard <pinard@iro.umontreal.ca>
9994 * Makefile.in: Group all *clean-recursive goals in one, using sed
9995 to remove `-recursive' while calling make recursively. Also, use
9996 a subshell for each recursive $(MAKE).
9997 Reported by Jim Meyering.
9999 * src/m4.h (memcpy): Define with bcopy for BSD systems.
10000 Reported by Kaveh R. Ghazi.
10002 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
10003 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
10006 * configure.in: Use date instead of touch for stamp-h.
10007 * Makefile.in (stamp-h.in): Idem.
10009 * Makefile.in (distclean, realclean): Force serial execution of

10027 Reported by John David Anglin.
10029 * doc/Makefile.in (texclean): Remove *.cps and *.fns too.
10030 Reported by Eric Backus.
10032 * Makefile.in, checks/Makefile.in, doc/Makefile.in,

10044 Reported by Kaveh R. Ghazi.
10046 * src/Makefile.in (TAGS): Remote -t from etags call.
10048 1994-09-02 François Pinard <pinard@iro.umontreal.ca>

10057 * Makefile.in (distclean-local): Delete config.log.
10058 Reported by Jim Meyering.
10060 Solidify frozen files with respect to -P:
10061 * src/m4.c: Have -P set prefix_all_buitins variable instead of
10062 calling a function by that name. Declare the variable.

10064 * src/builtin.c (builtin_init): Merge in functionality from
10065 previous prefix_all_buitins function, while making entries in the
10066 symbol table, but not modifying the builtin description itself.
10068 * src/freeze.c (reload_frozen_state): Add a useless `break;',
10069 because *many* compilers do not accept an empty `default:'.
10070 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
10071 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
10073 * configure.in: Use AC_TYPE_SIGNAL.
10074 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.
10075 Reported by Robert Bernstein.
10077 * checks/Makefile.in (check): Modify PATH so check-them will find
10078 m4 in the src directory.
10079 * Makefile.in (check): Don't.
10080 Reported by Akiko Matsushita and Jim Meyering.
10082 * src/output.c (make_room_for, output_character_helper): New

10084 a per buffer MAXIMUM_BUFFER_SIZE.
10086 * src/output.c (output_text): New function, for optimizing the
10087 output of strings of characters. Use it.
10089 1994-08-30 François Pinard <pinard@iro.umontreal.ca>

10092 * doc/Makefile.in, src/Makefile.in, examples/Makefile.in: New
10094 * Makefile.in: Adjusted.
10095 * configure.in: Configure new Makefiles.
10097 * m4.h: Declare STRING typedef. Use it for comment and quote
10098 strings, adjusting all references. (This is the rudiments of a
10099 beginning for the eventual withdrawal of NUL terminated strings.)
10100 * output.c (shipout_text): Accept a length parameter, and use it.
10101 All callers adjusted.
10103 1994-08-29 François Pinard <pinard@iro.umontreal.ca>
10105 * m4.h: Include <unistd.h> if it exists.

10125 * output.c (freeze_diversions): New function.
10126 * m4.h: Declare freeze_diversions.
10127 * freeze.c: Document frozen file format, revise it, call
10128 freeze_diversions to add diversions to frozen format, and code to
10129 reload them properly.
10130 * m4.c: Do not undivert automatically at end when status being
10131 frozen. Do not call builtin_init when reloading frozen state.
10133 Speed up diversion processing:
10134 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
10135 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
10136 structure and variables, cached variables out of output_diversion,
10137 reallocate_diversion_for and OUTPUT_CHARACTER.
10138 (shipout_text, make_diversion, insert_diversion): Adapted to new
10140 (insert_file): Use better buffering.

10148 1994-08-27 François Pinard <pinard@iro.umontreal.ca>
10150 * symtab.c (hack_all_symbols): Use hash_table_size instead of
10151 constant HASHMAX, for -H option to work better.
10153 * builtin.c (DECLARE): Simplify by using _ ().
10155 * freeze.c: New file.
10156 * Makefile.in: Compile it, distribute it.
10157 * m4.c: Recognize, document and process --freeze-state (-F) and
10158 --reload-state (-R) options. Pass a true flag to builtin_init
10159 only if no reloading some state.

10174 1994-08-15 François Pinard <pinard@iro.umontreal.ca>
10176 * m4.c (long_options): Use "error-output", the dash was missing.
10177 Reported by Akiko Matsushita.
10179 1994-08-12 François Pinard <pinard@iro.umontreal.ca>
10181 * m4.h: Include <sys/types.h>.
10182 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
10183 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
10185 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
10186 as size_t, not int.
10187 * builtin.c (dump_args): Declare len as size_t, not int.
10189 * debug.c: Prototype the forward declaration of debug_set_file.
10191 * builtin.c (m4_undivert): Replace div by file, for avoiding the
10192 shadowing of this variable.
10193 * output.c (insert_diversion): Idem.
10195 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
10196 (input_init): Duplicate default quote and comment strings.
10197 (set_quotes): Free previous quote strings in all cases. Duplicate
10198 even default quote strings.
10199 (set_comment): Free previous comment strings in all cases.
10200 Duplicate even default comment strings.
10202 * configure.in: Updated for Autoconf 2.0.
10203 * Makefile.in (distclean-local): Also delete config.cache.
10205 * m4.c (usage): Reorganize the --help output by topic. Include a
10206 description for debugging flags.
10208 1994-07-29 François Pinard <pinard@iro.umontreal.ca>
10210 * configure.in: If sigaction is available and SA_ONSTACK defined,
10211 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
10212 defined, use sigvec. Else don't compile stackovf.c.
10213 * stackovf.c (setup_stackovf_trap): Idem.
10214 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
10217 1994-07-21 François Pinard <pinard@iro.umontreal.ca>
10219 * m4.c (usage): Replace printf par fputs.
10221 1994-07-18 François Pinard <pinard@iro.umontreal.ca>
10225 1994-07-17 François Pinard <pinard@iro.umontreal.ca>
10227 * configure.in: Check for sigaction and sigvec. Add a new delayed
10228 check for RLIMIT_STACK, combine in the checking for getrlimit.
10229 All those things are not universally available.
10230 * stackovf.c: Split setting up the trap handler and catching
10231 signals, for better taking care of various configure outcomes.
10232 * examples/stackovf.sh: Correct a typo.
10233 Reported by Eric Backus, Jim Avera and Jim Meyering.
10235 1994-07-16 François Pinard <pinard@iro.umontreal.ca>
10237 * ansi2knr.c: New version sent by its author, Peter Deutsch.
10239 1994-07-15 François Pinard <pinard@iro.umontreal.ca>
10241 * Makefile.in: Modify so parallel make will not try making
10242 lib/libm4.a twice simultaneously.
10243 Reported by Jim Meyering.
10245 1994-07-14 François Pinard <pinard@iro.umontreal.ca>
10247 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
10248 error message, for when no code possibility exists. Even if this
10249 line is completely #ifdef'ed out, it brings a syntax error.
10250 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
10252 * Makefile.in (install): Have install depend on all too, for lib
10253 to be remade as needed.
10255 * examples/stackovf.sh: Try ksh, bsh and bash for shells
10256 providing ulimit, instead of using only ksh.
10257 Reported by Jim Avera and Joseph E. Sacco.
10259 1994-07-12 François Pinard <pinard@iro.umontreal.ca>
10261 * Makefile.in (check): Have it depend on all instead of m4. In
10262 this way, a change in lib will be detected and processed.
10264 * builtin.c (numeric_arg): Use strtol and verify the conversion,
10265 instead of using sscanf which stops as soon as there is a
10266 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
10267 and divert(1xyzzy) were all accepted without any warning or error
10269 * m4.h: Declare strtol as long if not including stdlib.h.
10270 * configure.in: Check for limits.h, and replace strtol if missing.
10271 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
10272 * lib/strtol.c: New file, from elsewhere.
10273 Reported by Andreas Schwab.
10275 1994-07-07 François Pinard <pinard@iro.umontreal.ca>
10277 * macro.c (expand_macro): Cast value to (boolean) prior to
10278 assigning it to traced.
10279 Reported by Tom McConnell.
10281 * Makefile.in (m4): Always make all in lib first.
10282 Reported by Jim Meyering.
10284 1994-07-06 Jim Avera <jima@netcom.com>
10286 * stackovf.c: Isolated OS-dependent sections; Improved portability,
10287 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
10288 handlers), and a default error message if the fault address is not
10289 available (when neither siginfo.h nor BSD sigcontext are supported).
10290 * configure.in: Changes for stackovf.h: Check for sigcontext,
10291 sigaction, sigstack, and define rlim_t as int if necessary.
10292 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
10293 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
10294 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
10296 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
10298 * configure.in: Use AC_SET_MAKE.
10299 * Makefile.in: Use @SET_MAKE@.
10300 Reported by Jim Meyering.
10302 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
10303 Reported by Ian Taylor.
10305 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
10307 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
10308 because siginfo.h is unrelated to standard headers, and siginfo.h
10309 is already checked for.
10310 Reported by Joseph E. Sacco.
10312 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
10314 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
10317 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
10319 * builtin.c (substitute): Use \& to represent this part of the
10320 string which was matched by the whole regexp, instead of
10321 representing the whole string. Any usage of \0 issues a warning
10322 and acts like \&, it will disappear in some subsequent release.
10324 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
10326 * m4.c: Complete prototype for forwarded declaration of usage.
10328 * input.c (init_macro_token): Correct own reference in error
10329 message. Previous name get_macro_func was referred to instead.
10330 (next_char): Correct own reference in error message. Previous
10331 name advance_input was referred to instead.
10333 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
10334 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
10335 and_term, not_term, logical_not_term, cmp_term, shift_term,
10336 add_term, mult_term, exp_term, unary_term, simple_term): Add
10337 prototype to forwarded declarations. Declare parameter v1 as
10338 eval_t * instead of int *. Same for local variable v2 in dyadic
10339 functions. Same for result in exp_term.
10340 * builtin.c (m4_eval): Declare value as eval_t instead of int.
10341 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
10342 unsigned_eval_t instead of unsigned int. Change casts accordingly.
10343 (shipout_int): Cast first argument of ntoa to eval_t.
10344 Reported by Thorsten Ohl.
10346 * macro.c: Complete the prototypes of forwarded expand_macro and
10348 Reported by Thorsten Ohl.
10350 * m4.h: Define voidstar as void * or char * depending on __STDC__.
10351 The Ultrix 3.1 compiler cannot do much with void pointers.
10353 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
10354 * m4.c (xfree): Replace void * by voidstar.
10355 Reported by Tom McConnell.
10357 * ansi2knr.1: New, from elsewhere.
10358 * Makefile.in (DISTFILES): Distribute ansi2knr.1
10360 * Makefile.in (stamp-h.in): Avoid running ./config.status if
10361 stamp-h does not exist yet. This avoids running it a second time
10362 just after the initial ./configure.
10363 Reported by David MacKenzie and Tom McConnell.
10365 * m4.h: Replace the enum debug_info declaration with a series of
10366 #define's. The Ultrix 3.1 compiler would otherwise need casting
10367 (int) to most references, when used in expressions.
10368 Reported by Tom McConnell.
10370 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
10372 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
10373 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
10374 calls the compiler. Previously, FP_PROTOTYPES was only calling
10375 the preprocessor; by not being subject to CFLAGS, this was
10376 discouraging those flags asking for ANSI compilation.
10377 * acconfig.h: Document HAVE_PROTOTYPES.
10378 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
10379 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
10380 Reported by Eric Backus.
10382 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
10383 from the environment. Default CFLAGS to -g if not set.
10384 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
10385 * lib/Makefile.in: Have CFLAGS substituted from configure.
10386 Reported by Eric Backus and Tom McConnell.
10388 * configure.in: m4_undefine changeword before using AC_ENABLE.
10390 * m4.h: Declare prototypes for error (for ANSI compilers only),
10391 prefix_all_builtins and reference_error.
10392 Reported by Tom McConnell.
10394 * input.c (set_word_regexp): Do not try to initialize the array
10395 test from a string, this does not work with non-ANSI compilers.
10396 Reported by Eric Backus.
10398 * Makefile.in (dist): Clean examples/ before saving it.
10399 (distclean-local): Also remove stamp-h.
10400 Reported by Eric Backus.
10402 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with

10480 1994-06-22 François Pinard <pinard@iro.umontreal.ca>
10482 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
10483 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
10484 also tested it on a Sun Sparc workstation running SunOS 4.x.
10486 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
10487 49.format check, abusing a `union values' argument with sprintf
10488 without selecting the proper field. Now, save the formatting type
10489 first, delaying the fetch of the corresponding argument.
10490 Reported by Joseph E. Sacco and Tom Quinn.
10492 * format.c (format): Remove const from char *fmt declaration when
10493 not HAVE_EFGCVT, because a NUL may be forced into it.

10496 Reported by Joseph E. Sacco.
10498 * Regenerate configure using Autoconf 1.11, this corrects a

10539 warning from gcc about `repl' possibly used before defined.
10540 Reported by Jim Meyering.
10542 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
10543 Reported by Jim Meyering.
10545 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
10547 * m4.h: Move the conditional definition of volatile after the
10548 inclusion of system files, because they may define it first.
10550 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
10552 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
10553 get around a problem with Alpha make seeing a syntax error, there.

10576 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
10577 syserr() macro. Delete errref, add reference_error and M4ERROR.
10578 * m4.c: Replace errref, which was returning an input reference
10579 string, with reference_error, which prints it on standard error.
10580 * builtin.c, output.c: Use errno as second parameter to error,
10581 instead of using syserr() with %s.
10582 * *.c: Use M4ERROR instead of error: no more errref() with %s.
10583 Doing so, the program name appears after the input reference
10584 instead of before, which eases M-x next-error processing.
10586 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
10588 * checks/get-them: Escape braces with backslashes in patterns,

10625 * input.c (input_init): Initialize quote and comment strings
10626 explicitely instead of calling set_quotes and set_comment: by
10627 doing so, we ensure we do not free uninitialized variables.

10630 expected is on the left and the obtained on the right.
10632 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
10633 macros. Delete declarations for m4error, warning, fatal and
10634 internal_error, add declaration for error_message_prefix.
10635 * m4.c: Delete m4error, warning, fatal and internal_error
10636 routines, add error_message_prefix routine.
10637 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
10638 warning with WARNING*, fatal with FATAL* and internal_error with
10640 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
10641 this is not needed anymore.
10643 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and

10646 * debug.c: Remove static specifier for FILE *debug declaration.
10647 Delete debug_print and debug_message routines, add
10648 debug_message_prefix routine.

10906 * Makefile.in: Add DEFS to MDEFINES.
10907 * lib/Makefile.in (.c.o): Remove $(CPPFLAGS).
10908 (libm4.a): Remove the library before creating it.
10909 (distclean): Remove tags and TAGS too.
10911 1992-12-23 François Pinard <pinard@iro.umontreal.ca>
10913 * Makefile.in (dvi, m4.dvi): New goals.
10915 * builtin.c, eval.c, format.c, input.c, m4.[ch], m4.texinfo,
10916 macro.c, output.c, path.c, symtab.c: Change Copyright from
10917 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
10919 * examples/divert.m4: Deleted, this bug has been corrected.
10921 * Makefile.in (texclean, mostlyclean): New goals.
10923 * Makefile.in (clean): Remove clutter from ansi2knr.
10924 Reported by Pierre Gaumond.
10926 1992-12-20 François Pinard <pinard@iro.umontreal.ca>
10928 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
10929 might well use CFLAGS is s/he needs it.
10931 * Makefile.in: Allow installation of info files from a separate
10933 Reported by Jason Merrill.
10934 Reported by David MacKenzie.
10935 Reported by Skip Montanaro.
10936 Reported by Erez Zadok.
10937 Reported by Assar Westerlund.
10939 1992-12-19 François Pinard <pinard@iro.umontreal.ca>
10942 This is still a beta release for the future GNU m4 version 1.1.
10944 * lib/alloca.c: New, from elsewhere.
10945 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
10947 * m4.h: Do not define index/rindex if already defined. If
10948 FALSE/TRUE are already defined, do not redefine them, but merely
10949 define boolean typedef to int.
10951 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
10952 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
10953 because some C compilers do not like connectives with #ifdef.
10954 * m4.h: Define `volatile' only if __GNUC__, instead of once for
10955 __GNUC__ and once for __STDC__.
10956 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
10958 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
10959 Makefile dependencies. Without it, make keeps destroying and
10960 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
10962 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
10963 to diversion/DIVERSION, this was a spelling error.
10965 * m4.c: Declare version[], remove #include "version.h".
10966 * version.h: Deleted.
10967 * Makefile.in: Remove references to version.h.
10969 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
10970 production, by using a simpler and more robust algorithm. This
10971 solves the problem of synclines sometimes written in the middle of
10972 an output line. Delete sync_line() and output_lines variable.
10973 * m4.h: Remove sync_line prototype and output_lines declaration.
10974 * input.c (next_char), output.c (shipout_text): Remove references
10976 * input.c (push_file, pop_file): Merely put the value -1 in
10977 output_current_line instead of calling sync_line, for delaying a
10978 single `#line NUM FILE' before next output line. Do not test
10979 for sync_output, because this is unnecessary clutter.
10980 * output.c (make_divertion, insert_divertion): Idem.
10981 * input.c: Rename must_advance_line to start_of_input_line, for
10984 * debug.c (trace_header): Select a new debug line format, which
10985 better complies with GNU standards for formatting error messages.
10986 With option `-dfl', M-x next-error might be used on the output.
10987 * m4.c (vmesg): Adjust format of error output to GNU standards.
10988 * m4.texinfo: Adjust examples for `make check' to work.
10990 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
10991 case for enum debug_info constants, which were all lower case.
10993 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
10995 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
10996 collected patches. I tried a few times using newer regex.[ch], it
10997 mysteriously stopped aborting with this one. Insecure feeling...
10998 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
11000 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
11002 * m4.c: Change `--no-warnings' to `--silent'.
11003 Reported by David MacKenzie.
11005 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
11006 leave it off for now. See comment in m4.c for justification.
11007 Reported by David MacKenzie.
11009 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
11010 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
11012 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
11014 * Makefile.in: Ensure recursive cleaning is done before local
11015 cleaning for all clean goals.
11017 * builtin.c (ntoa): Ensure the value is always interpreted as a
11018 signed quantity, whatever the radix is.
11020 1992-11-18 Jim Meyering <meyering@idefix>
11022 * builtin.c, format.c, input.c: Split long lines.
11023 * m4.c: Use typedef macro_definition instead of struct
11025 * symtab.c: Use typedef symbol instead of struct symbol.
11027 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
11029 * *.[ch]: Remove all trailing whitespace, in code and comments.
11031 * configure.in: Find some awk.
11032 * Makefile.in: Add $(AWK) to MDEFINES.
11033 * checks/Makefile.in: Transmit $(AWK) to get_them.
11034 * checks/get_them: Use $AWK instead of gawk. Add a close in the
11035 awk script when switching files, because without this, mawk runs
11036 out of file descriptors.
11038 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
11040 * Makefile.in (realclean): Delete m4.info*.
11041 Reported by Jim Meyering.
11043 * Makefile.in: Adjust and link with checks/Makefile.
11044 * checks/Makefile.in: New.
11045 * configure.in: Output checks/Makefile.
11047 * checks/get_them: Have the dnl header of each test more
11048 recognizable by next-error, also use a better message.
11050 1992-11-16 Jim Meyering <meyering@idefix>
11052 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
11053 And use that only if __GNUC__ since we're using it's GCC-specific
11054 semantics that tell the compiler the associated function doesn't
11057 * builtin.c (substitute): Don't use character as an array index.
11058 (dumpdef_cmp): Make formal arguments `const void *' to avoid
11059 warnings with gcc -W -Wall on systems with qsort prototype.
11060 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
11063 * eval.c (most functions): Add parentheses to assignments used
11064 as truth values go avoid warnings from gcc -Wall.
11066 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
11067 any functions that don't need external scope.
11069 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
11070 (many functions and arrays): Declare `const'.
11072 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
11074 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
11075 removing the declaration from m4.h. Also rename false to FALSE
11078 * lib/Makefile.in (Makefile): New goal.
11080 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
11081 so heavily loaded. It gets more easily overridable, calling make.
11082 Reported by Jim Meyering.
11084 * Makefile.in (dist): Get .fname from the current directory name,
11085 instead of from version.h. I need updating many files manually,
11086 when the version changes, version.h is just one of them.
11088 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
11090 * m4.h: Remove the tag `boolean' on the enum introducing typedef
11091 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
11092 Reported by Tom McConnell.
11094 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
11096 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
11097 39.cleardiv, which were describing missing or spurious newlines.
11098 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
11099 do not depend on machine word size, `/bin/false' implementation,
11100 or `wc' output format. `make check' is more dependable, now.
11102 * checks/check_them: Summarize the failed tests by listing their
11103 name, at end. If none, issue `All checks successful'. Output
11104 `Checking' instead of `Input file:'.
11106 * checks/get_them, checks/check_them: Reindented.
11108 * Makefile.in (dist): chmod a+r before making the tar file.
11110 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
11112 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
11114 * input.c (next_token): Reinitialize token_buttom just after using
11115 it as a watermark with obstack_free. Or else, a future token, big
11116 enough for triggering reallocation of the obstack chunk, could
11117 void the initialized value of token_buttom, later causing panic in
11118 obstack_free. Rename token_buttom to token_bottom everywhere.
11120 * m4.h: Before declaring errno, first include <errno.h> and
11121 ensure that it does not define errno.
11122 Reported by Richard Stallman.
11124 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
11126 * builtin.c: Define and use DECLARE macro for builtins.
11128 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
11129 argument, this is a common idiom for introducing long comments.
11131 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
11132 arguments. The last argument was silently ignored.
11134 * m4.c (cmd_error): Add a missing semicolon before va_end().
11136 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
11138 * Makefile.in: Now handle protoized sources. Define and use U.
11139 Compile and use ansi2knr with old compilers. Update DISTFILES.
11140 Add `aclocal.m4' to `configure' dependencies.
11141 * ansi2knr.c: New, from Ghostscript distribution.
11142 * configure.in: Define U through FP_PROTOTYPES for old compilers.
11143 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
11144 * aclocal.m4: New, provide FP_PROTOTYPES.
11145 * m4.h: Conditionnaly protoized through Args, save for varags.
11146 * builtin.c: Protoized. Then:
11147 Include <sys/types.h> if size_t is not defined, before "regex.h".
11148 (m4_ifelse): Fetch built-in name properly for diagnostic.
11149 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
11150 (m4_regexp): Add const to `msg' declaration.
11151 (m4_patsubst): Add const to `msg' declaration.
11152 * debug.c: Protoized, save for varargs.
11153 * eval.c: Protoized.
11154 * format.c: Protoized.
11155 * input.c: Protoized.
11156 * m4.c: Protoized, save for varargs. Then:
11157 (xfree): Accept void * instead of char *.
11158 (xmalloc): Return void * instead of char *.
11159 (xrealloc): Accept and return void * instead of char *.
11160 * macro.c: Protoized.
11161 * output.c: Protoized.
11162 * path.c: Protoized. Then cast some (char *) over xmalloc's.
11163 * symtab.c: Protoized.
11165 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
11167 * m4.texinfo: Remove directory from diagnostics in 30.include,
11168 51.eval, 56.errprint and 57.m4exit tests.
11170 * m4.h: Remove declarations for int or void system functions, they
11171 cause more conflicting trouble than they make good.
11173 * configure.in: Avoid configuration header file. Add some tests.
11174 * m4.h: Remove #include "config.h".
11175 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
11176 Then, rewritten for better compliance with GNU standards.
11178 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
11180 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
11181 because of a misplaced #endif.
11183 * Many *.[hc] files: Correct intra-line spacing here and there,
11184 according to GNU indent 1.6 advice.
11186 * configure.in: New, using Autoconf 1.2.
11187 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
11188 * Delete old configure.in, configure, etc/configure.in,
11189 etc/configure, lib/configure.in, lib/configure and config/*.
11190 Reported by Jason Merrill.
11192 * symtab.c (hash): Change (char) NULL to '\0'.
11193 Reported by Jason Merrill.
11195 * Delete .vers, etc/newdist.sh, etc/newvers.sh and
11196 etc/nextvers.sh. Release numbers will be edited `by hand'.
11197 * version.h: De-automatize, force value in.
11199 * m4.c: Changes in order to use a newer getopt.h.
11200 Reported by David MacKenzie.
11202 * checks/: New name for examples/.
11203 * checks/get_them: New location for etc/get_examples.
11204 * checks/check_them: New location for etc/check_examples.

11212 * Makefile.in (check): Add m4 as dependency.
11214 * m4.c: Accept --no-warnings instead of --no_warnings, and
11215 --no-gnu-extensions instead of --no_gnu_extensions. Make the
11216 usage message more informative.
11217 Reported by David MacKenzie.
11219 1992-03-09 François Pinard <pinard@iro.umontreal.ca>
11221 * etc/check_examples: New name for check_examples.sh.

11228 code disposition by hand.
11230 1992-03-08 François Pinard <pinard@iro.umontreal.ca>
11232 * m4.h: Delete definitions for abort() and exit().
11233 Reported by Richard Stallman.
11235 * config/hmake-unicos, config/s-unicos.h: New files.
11236 Reported by Hal Peterson.

11249 reports and feedback.
11251 * Uses GNU configure, taken from the gdb distribution.
11253 * Uses GNU getopt(), with long option names.
11255 * The -Q/+quiet option is added, which suppresses warnings about
11256 missing or superflous arguments to built-in macros.
11258 * Added default options via the M4OPTS environment variable.
11260 * The built-in format can now be configured to use sprintf as
11261 the formatting engine, for systems without [efg]cvt(3).
11263 * GNU library code is moved to the ./lib subdirectory; other
11264 utility files are now in ./etc.
11266 * Several minor bugs have been fixed.
11268 1991-07-26 René Seindal <seindal@diku.dk>
11270 * Fixed various bugs. Release 0.99, manual 0.09. Many thanks to
11271 François Pinard and Roland H. Pesch for providing me with reports.
11273 * The builtins incr and decr are now implemented without use of
11276 * The builtin indir is added, to allow for indirect macro calls
11277 (allows use of "illegal" macro names).
11279 * The debugging and tracing facilities has been enhanced
11280 considerably. See the manual for details.
11282 * The -tMACRO option is added, marks MACRO for tracing as soon
11285 * Builtins are traced after renaming iff they were before.
11287 * Named files can now be undiverted.
11289 * The -Nnum option can be used to increase the number of
11290 divertions available.
