1933 * Makefile.am (src_m4_SOURCES): Only compile shipped getopt module
1934 if the system getopt fails M4_GETOPT tests.
1936 2006-06-22 Eric Blake <ebb9@byu.net>
1938 * Makefile.am (EXTRA_DIST): Distribute gnulib-cache.m4.

1949 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1951 * Makefile.am (src_m4_DEPENDENCIES): Make dependency explicit.
1952 (clean-local): Split into and depend upon...
1953 (clean-local-tests, clean-local-src): ...these two. The latter
1954 removes the libtool object directory below `src', to work around
1955 a buglet in Automake, failing to list it.
1956 (EXTRA_DIST): Distribute modules/perl.c.
1958 2006-06-19 Eric Blake <ebb9@byu.net>
1960 * Makefile.am ($(srcdir)/doc/m4.1): No need to list $(srcdir) in
1961 right side of dependency; VPATH does that.

1963 (EXTRA_DIST): Distribute stamp-vcl.
1964 Reported by Ralf Wildenhues.
1965 (TESTSUITE): Revert earlier change that used absolute path, as
1966 that broke 'make dist' in VPATH. Stick with $(srcdir) instead.
1967 (EXTRA_DIST): Revert earlier change of $(TESTSUITE).
1968 (TESTS_ENVIRONMENT) [USE_GMP]: Revert earlier addition, since
1969 atlocal takes care of it instead.
1970 (check-local, installcheck-local, clean-local): Inline absolute
1971 path to testsuite here, rather than relative path to testsuite
1974 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1976 * m4/m4private.h (DELETE): Cast away const here...

1991 Follow recommendations from autoconf manual for autotest.
1992 * Makefile.am (TESTSUITE): Factor the $(srcdir) out of uses, and
1993 turn it into an absolute path until autotest provides an option
1994 that allows us to avoid changing directories. Properly quote
1996 (TESTS_ENVIRONMENT) [USE_GMP]: Inform testsuite about GMP.
1997 (check-recursive): Delete unused target.
1998 ($(TESTSUITE)): Atomically update testsuite.
1999 (CD_TESTDIR): Simplify.
2000 (m4__cd): Delete unused macro.
2001 (check-local): Let TESTSUITEFLAGS influence the run.

2025 * ltdl/m4/m4-gnulib.m4: Delete, no longer needed.
2027 Reduce compiler warnings. Inside GMP, mpq_t is an array type, so
2028 const mpq_t is not assignable from plain mpq_t. Avoid
2029 type-punning warnings caused trying to mix these types.
2030 * modules/mpeval.c (numb_ior, numb_eor, numb_and, numb_lshift),
2031 (numb_rshift, numb_divide, numb_modulo): Remove const qualifier.

2058 * bootstrap: Do not run libtoolize manually, this is done
2059 correctly by autoreconf. Invoke autoreconf with --no-recursive
2060 to avoid unnecessary rerunning of autotools for libltdl.
2062 2006-06-13 Eric Blake <ebb9@byu.net>
2066 2006-06-12 Eric Blake <ebb9@byu.net>
2068 * m4/output.c [HAVE_MKTEMP]: Gnulib provides mkstemp, so don't
2070 * src/m4.h: Don't declare mktemp.
2071 * m4/input.c (m4__next_token): Avoid bzero.
2072 * configure.ac (AC_CHECK_FUNCS): Remove obsolete checks.
2073 * Makefile.am (doc/m4.1): Depend on installed help2man, rather
2074 than distributing outdated helptoman.pl.

2077 2006-06-10 Eric Blake <ebb9@byu.net>
2079 * README (Patches): Document the current dependence on CVS

2088 (AC_PROG_AWK, AM_C_PROTOTYPES, AC_C_CONST, AC_HEADER_STDC),
2089 (AC_CHECK_HEADERS, AC_FUNC_ALLOCA, AC_FUNC_VPRINTF): Remove checks

2104 * BACKLOG: Delete. This file is too old and unmaintained to be
2106 * ChangeLog: Change encoding to UTF-8.
2108 Avoid compiler warnings.
2109 * m4/macro.c (trace_format): Don't mark this as a printf format,
2110 since we don't accept the same set of modifiers as printf. It
2111 would be nice if gcc let us specify a custom format archetype.
2112 * src/main.c (main): Cast away const.
2114 2006-06-10 Andreas Schwab <schwab@suse.de> (tiny change)

2134 * po/Makevars (MSGID_BUGS_ADDRESS): Add.
2135 * po/POTFILES.in (src/getopt.c, src/version-etc.c): These files live
2138 2006-05-06 Eric Blake <ebb9@byu.net>
2140 * configure.ac (LT_CONFIG_LTDL_DIR): Inform libtool which
2141 subdirectory to use.

2164 2005-12-05 Gary V. Vaughan <gary@gnu.org>
2166 * bootstrap (func_update_po): Synch with CVS GNU tar. wget 1.9.x
2167 and 1.10.x support --cache=off, so $WGETFLAGS are not necessary.
2168 Reported by Eric Blake <ebb9@byu.net>
2170 2005-12-04 Gary V. Vaughan <gary@gnu.org>
2172 * bootstrap (func_update_po): Test and set $WGETFLAGS to disable
2173 http caching as -C is no longer supported by wget 1.10.x.
2174 Reported by Eric Blake <ebb9@byu.net>
2176 2005-10-20 Gary V. Vaughan <gary@gnu.org>
2178 * m4/module.c (caller_id): To match libtool-2.0 interface, changed
2180 (iface_id): ...an lt_dlinterface_id type.
2181 (m4__module_find): New abstraction for lt_dlhandle_fetch. Use
2182 throughout, instead of calling obsolete lt_dlhandle_find directly.
2183 (m4__module_next): Use multiloader-safe lt_dlhandle_iterate. Use
2184 throughout, instead of calling obsolete lt_dlhandle_next.
2185 * m4/m4private.h (m4__module_find): Declare it.

2195 these files under source control anymore.
2196 Suggested by Eric Blake <ebb9@byu.net>
2198 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
2200 * ltdl/m4/m4-gnulib.m4: Update FSF contact address. Somehow this
2201 file escaped the address updates on 2005-05-01.
2203 2005-07-07 Gary V. Vaughan <gary@gnu.org>
2205 * bootstrap: Allow user overriding of gnulib-tool location, and
2206 correctly determine module source directories whether gnulib-tool
2207 is given as a relative or absolute path, or is found by searching
2209 Reported by Eric Blake <ebb9@byu.net>

2228 level symbol rename.
2229 * m4/m4module.h (m4_symbol_rename): Declare it as part of the API.
2230 * modules/gnu.c (regsub): Factored out of m4_epatsubst_do...
2231 (m4_patsubst_do, m4_renamesyms_do): ...wrappers that use
2233 (erenamesyms, renamesyms): ...builtins that use these to implement
2234 macro renaming by regular expression.
2235 * doc/m4.texinfo (Erenamesyms and Renamesyms): Document them.
2236 * tests/generate.awk: Allow some forbidden `m4_' prefixed symbols
2237 to stop the new generated tests from choking.
2239 2005-05-07 Gary V. Vaughan <gary@gnu.org>
2241 Since most of the build is handled from a single Makefile.am now,
2242 we can teach make about the dependencies between the m4 binary and
2243 the preopened modules it is built against:
2245 * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
2247 * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
2248 of the preopened modules have changed.
2250 2005-05-07 Gary V. Vaughan <gary@gnu.org>
2252 * configure.ac (gl_MODULES): Add mkstemp for machines that don't
2253 have a native implementation.
2255 2005-05-06 Gary V. Vaughan <gary@gnu.org>
2257 * src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are
2258 handled already by gnu/exit.h.
2260 * configure.ac (gl_MODULES): Add assert to support a
2261 --disable-assert configure time option for NDEBUG setting.
2263 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.
2264 * bootstrap (src_modules): Add version-etc-fsf.
2265 * src/main.c (version_etc_copyright): Removed.
2267 * ltdl/m4/m4-getopt.m4 (m4_GETOPT): Synch with gnulib/getopt.m4.

2271 * src/m4.h (__CYGWIN__, WIN32): Canonicalise Windows and Cygwin
2273 * src/freeze.c (produce_frozen_state): Use \n line-endings even
2274 on Windows, so that the frozen file reader will work.

2277 2005-05-04 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
2279 Forward port of a patch that allowed m4-1.4.2 to compile on
2282 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
2284 * src/m4.h: And include them as appropriate.
2285 * src/main.c, src/stackovf.h: Don't include signal.h literally;
2286 m4.h will include the correct file.
2288 2005-05-04 Gary V. Vaughan <gary@gnu.org>
2290 * m4/m4private.h: Make errno visible for the sources patched
2293 2005-05-04 Paul Eggert <eggert@twinsun.com>
2295 * src/main.c (print_program_name_CB): Preserve errno, since
2296 M4ERROR relies on this.
2297 * modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
2298 * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
2299 * m4/path.c (m4_path_search): Don't let "free" trash errno when
2302 * m4/output.c (m4_insert_file): Don't assume errno has a valid
2303 value simply because fread returns zero. This fixes a
2304 portability bug reported by Marion Hakanson in
2305 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
2307 2005-05-04 Santiago Vila <sanvila@debian.org>

2314 * m4/output.c (m4_insert_file): Do not mix buffered and
2315 unbuffered I/O, as this breaks on the Hurd.
2317 2005-05-04 Gary V. Vaughan <gary@gnu.org>
2319 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
2320 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
2321 and libtoolize does a better job of ltdl importing now too, so
2322 take advantage of that while updating the tree:
2324 * acm4, config: Moved from here...
2325 * ltdl/m4, ltdl/config: ...to here.
2326 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
2327 src/Makefile.am, tests/Makefile.am: Removed...
2328 * Makefile.am: ...and migrated to here, with adjustments to
2329 compensate for relative path differences.
2330 * commit: Adjust relative paths.
2331 * configure.ac: Adjust relative paths.
2332 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
2334 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
2335 the meanwhile, CVS HEAD libtool is needed.
2336 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
2337 stricly new enough, we also need a patch.
2338 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
2339 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
2340 (gl_MODULES): Don't list getopt and version-etc, as they don't
2342 * bootstrap: After running gnulib-tool to import the listed
2343 modules, fetch getopt and version-etc into src manually.
2344 (ltdldir): Change to ltdl.
2345 * src/main.c: Adjust for changes in version-etc API.
2346 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
2347 but works when the getopt module isn't to be included in the lib.
2348 * README: Add note about patching autoconf and automake to

2354 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
2355 empty file rather than to a nonexistent file. This closes a
2356 common security hole.
2357 * modules/m4.c (m4_maketemp): Implement the above, by using
2358 mkstemp rather than mktemp.

2407 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
2408 (m4_is_syntax_macro_escaped): Similarly protect function
2409 definitions from macro expansion under -DNDEBUG by #undefing the
2410 matching macro names before each definition. Also, move all the
2411 function definitions to the end of the file so that any
2412 invocations in the rest of the file pick up the fast macro

2419 option setter functions.
2421 2004-09-23 Gary V. Vaughan <gary@gnu.org>
2423 * po/POTFILES.in: Reflect move of gnulib files from gnulib/m4
2426 2004-09-23 Gary V. Vaughan <gary@gnu.org>
2428 * src/main.c: Include gnulib files from the correct directory.
2430 * gnulib/*: Don't store any of the gnulib files in arch, as they
2431 generate spurious changes.
2432 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
2433 gnulib macros now share our macro directory.
2434 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
2435 * bootstrap: Call gnulib-tool to import from the gnulib tree.
2436 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
2437 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
2438 the gettext macros from autopoint that overwrite the gnulib-tool
2439 imported versions. Import sources and Makefile.am into the `gnu'
2440 directory. Changed all callers.
2441 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
2442 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
2443 for imported modules.
2444 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
2445 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
2446 hardcoding the gnulib macros they wrap.
2448 2004-07-15 Gary V. Vaughan <gary@gnu.org>
2450 Latest CVS libtool can preload modules in libraries, including
2451 its own module loaders! Tweak m4 so that it doesn't try to treat
2452 libltdl's module loaders as m4 modules when freezing and on exit:
2454 * gnulib/acm4/*.m4: Don't store these files in arch since they
2455 generate spurious changes.
2456 * bootstrap: Simplify initial libtoolize call, since CVS
2457 libtoolize is smarter these days.
2458 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
2460 * m4/module.h (m4__module_exit): Missing declaration.
2461 * m4/m4private.h (m4__module_next): New function declaration.
2462 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
2463 encapsulation. Changed all callers.
2464 (m4__module_interface): New function to verify m4 loadable module
2466 (m4__module_init): Register the interface validator.
2467 (m4__module_exit): Only close my own modules.
2468 * modules/m4.c (unistd.h): Provide missing declaration.
2469 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
2470 (m4_expand_ranges): More missing declarations.
2471 * modules/modtest.c (export_test): Ditto.
2472 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
2473 * src/main.c (main): Bump copyright year.
2474 * tests/modules.at: Fix sed syntax error.
2477 2004-06-17 Gary V. Vaughan <gary@gnu.org>
2479 Tweaking to enable compilation with latest CVS libtool and
2480 libltdl. We can't just dump the library files directly into the
2481 m4 directory anymore now that libltdl is built from pieces itself:
2483 * bootstrap: Rewritten to use latest libtoolize sanely, and to
2484 set up libltdl subdirectory.
2485 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
2486 gnulib subdirectory's config.
2487 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
2488 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
2490 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
2491 configure.ac, so use AC_WITH_LTDL instead.
2492 * Makefile.am (SUBDIRS): Add libltdl.
2493 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
2495 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
2496 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
2497 (libm4_la_LIBADD): Add LIBLTDL.
2498 * m4/ltdl.c, m4/ltdl.h: Removed.
2499 * m4/m4module.h: Include canonical ltdl.h.
2502 2004-06-14 Gary V. Vaughan <gary@gnu.org>
2504 * gnulib/import: Now updates makefile fragments, and configure.ac.
2505 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
2506 * gnulib/m4/Makefile.am: include it.
2507 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
2508 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
2509 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
2510 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
2511 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
2512 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,
2513 gnulib/acm4/lib-ld.m4, gnulib/acm4/lib-prefix.m4,
2514 gnulib/acm4/error.m4, gnulib/acm4/po.m4, gnulib/acm4/regex.m4,
2515 gnulib/acm4/stdbool.m4, gnulib/acm4/stdint_h.m4,
2516 gnulib/acm4/uintmax_t.m4, gnulib/acm4/ulonglong.m4,
2517 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
2518 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
2519 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
2521 * gnulib/m4/getopt_int.h: New source file from latest gnulib
2523 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
2524 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,
2525 gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
2526 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
2527 Updated source files from latest gnulib.
2529 2004-02-29 Gary V. Vaughan <gary@gnu.org>
2531 * config/mailnotify: New file for mailing commit notifications,
2532 imported from cvs-utils.
2533 * commit: Updated from cvs-utils and tweaked for m4.
2535 2003-12-01 Gary V. Vaughan <gary@gnu.org>
2537 * config/mkstamp: Updated from CVS libtool.
2538 * configure.ac: Generate a gnu coding standards compliant version
2539 number, and use it for the banner.
2540 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
2541 mhen the TIMESTAMP changes in ChangeLog, but the file modification
2542 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
2543 contain the previous version number.
2544 * src/main.c: Make --version output conform to the GNU standard.
2546 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
2547 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
2548 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
2549 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
2550 time_la_SOURCES): ...so that these are defaulted correctly, and
2551 can be removed from this file.
2552 (AM_LDFLAGS): Add -module...
2553 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
2554 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
2555 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
2556 the individual settings can be removed.
2557 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
2558 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
2559 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
2560 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
2561 time_la_LIBADD): ...so that these are picked up as a deplib of
2562 libm4 and don't need to be set explicitly.
2564 2003-11-18 Gary V. Vaughan <gary@gnu.org>
2566 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
2567 from the standard build. It is too fragile.
2569 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
2570 CVS libtool after merging m4 changes across to libtool.
2572 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
2573 * m4/path.c (search_path_add): Ditto.
2575 2003-11-13 Gary V. Vaughan <gary@gnu.org>
2577 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
2578 libtool tags we don't use in configure. This reduces the size
2579 of the script from over 1Mb to under 700Kb.
2581 2003-11-13 Gary V. Vaughan <gary@gnu.org>
2583 The import script was not written properly, and the last gnulib
2584 import was incomplete. Fixed that problem, and reimport our
2585 gnulib dependencies, which picks up the address calculation
2586 overflow checks described by Paul below. Also tweak the clients
2587 of the gnulib xalloc module not to use deprecated macros:
2589 * gnulib/import: Recurse through module dependencies rather than
2590 naively descending only one level.
2591 * configure.ac: Add calls to gnulib's strnlen and extension module
2593 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
2595 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
2596 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
2597 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
2598 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
2600 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
2601 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
2602 place of `xcalloc (1, S)'.
2603 * m4/m4.c (m4_create): Likewise.
2604 * m4/m4private.h (m4_symbol_value_create): Likewise.
2605 * m4/symtab.c (symtab_fetch): Likewise.
2606 * m4/syntax.c (m4_syntax_create): Likewise.
2607 * src/freeze.c (reload_frozen_state): Likewise.
2608 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
2610 * m4/symtab.c (m4_symtab_create): Likewise.
2612 2003-11-13 Gary V. Vaughan <gary@gnu.org>
2614 * tests/module.at: Comment typo.
2616 2003-10-10 Gary V. Vaughan <gary@gnu.org>
2618 * tests/modules.at (modules: importing): Apply some lateral
2619 thinking, and use AT_CHECK to compare the output of a sed pass
2620 over stderr against the canonical strerror string.
2622 * tests/modules.at (modules: importing): Edit the generated stderr
2623 output to canonicalize strerror output, before a comparison.
2625 2003-10-10 Gary V. Vaughan <gary@gnu.org>
2627 Tru64UNIX perl is sloppy with namespace pollution. This patch is
2628 careful not to trip over the mess:
2630 * modules/perl.c: Some builds of perl install headers that contain
2631 `#define try __builtin_try'. Be sure to undefine that macro
2632 before `m4/hash.h' gets included, which uses the `try' symbol.
2633 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
2634 `false' before including `stdbool.h'.
2635 (DELETE): This symbol is not in m4's namespace, and is in any
2636 case only used internally...
2637 * m4/m4private.h (DELETE): ...so move it to here.
2638 Reported by Martin MOKREJS <mmokrejs@natur.cuni.cz>
2640 2003-10-08 Paul Eggert <eggert@twinsun.com>
2642 Don't use XMALLOC and XCALLOC. Once we install the
2643 corresponding patch into gnulib, this will fix some
2644 address-calculation overflow bugs on hosts where calloc (A, B)
2645 returns garbage when A*B overflows.
2647 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
2648 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
2649 xmalloc, XCALLOC with xcalloc.
2650 * m4/m4.c (m4_create): Likewise.
2651 * m4/m4private.h (m4_symbol_value_create): Likewise.
2652 * m4/output.c (m4_output_init): Likewise.
2653 * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise.
2654 * m4/syntax.c (remove_syntax_attribute): Likewise.
2655 * src/freeze.c (reload_frozen_state): Likewise.
2656 * src/main.c (main): Likewise.
2658 2003-10-07 Gary V. Vaughan <gary@gnu.org>
2660 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
2661 gnulib/acm4 directories for aclocal m4 macros.
2662 * gnulib/Makefile.am (EXTRA_DIST): Removed.
2663 (MAINTAINERCLEANFILES): Add Makefile.in.
2664 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
2666 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
2667 * gnulib/import: New file. Temporary script for updating gnulib
2668 imported files, until gnulib-tool is working.
2669 * gnulib/config/codeset.m4, gnulib/config/error.m4,
2670 gnulib/config/exitfail.m4, gnulib/config/extensions.m4,

2706 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
2707 gnulib/acm4/xstrndup.m4: Reimported from CVS gnulib with
2708 gnulib/import script.
2709 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/error.c,
2710 gnulib/m4/error.h, gnulib/m4/exitfail.c, gnulib/m4/free.c,

2713 gnulib/m4/version-etc.c, gnulib/m4/version-etc.h,
2714 gnulib/m4/xalloc.h, gnulib/m4/xmalloc.c: Updated from CVS
2715 gnulib with gnulib/import script.
2716 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
2717 guards ready for gnulib-tool to autoupdate on import.
2718 * config/debug.m4, config/gmp.m4, config/m4-error.m4,
2719 config/m4-gettext.m4, config/m4-obstack.m4, config/m4-regex.m4,

2734 2003-09-16 Gary V. Vaughan <gary@gnu.org>
2736 * gnulib/m4/version-etc.c, gnulib/m4/version-etc.h: Import
2737 version-etc module from CVS gnulib.
2738 * po/POTFILES.in: Add gnulib/m4/version-etc.c.
2739 * src/Makefile.am: Build it.
2740 * src/main.c: Use it.
2742 * gnulib/m4/exit.h: Import exit module from CVS gnulib.
2743 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
2744 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
2747 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
2748 Gary V. Vaughan <gary@gnu.org>
2750 * bootstrap: Separate options.
2751 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
2752 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
2754 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
2755 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
2756 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
2757 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
2758 $(LTLIBINTL) for gettext support on cygwin.
2759 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
2760 have $(LTLIBINTL) from the preloaded module la files.
2761 * README: Remove the warning about using --disable-nls on Windows
2764 2003-09-15 Gary V. Vaughan <gary@gnu.org>
2766 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
2767 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
2770 2003-09-12 Gary V. Vaughan <gary@gnu.org>
2772 * doc/STYLE: Document the gnulib header naming conventions, and
2774 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
2775 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,

2783 (gl_FUNC_STRTOL): In favour of the module macro.
2785 2003-09-12 Gary V. Vaughan <gary@gnu.org>
2787 Replace the getopt code with CVS gnulib getopt. The source files
2788 detect whether they are in a glibc environment and preprocess away
2789 all of the code if there is a system getopt, so we can compile
2790 them into the m4 executable unconditionally:
2792 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
2793 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
2794 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
2796 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
2798 * src/Makefile.am: Adjust.
2799 * src/main.c: Always include our shipped getopt.h.
2800 * po/POTFILES.in: Use new location of getopt.c.
2802 2003-09-12 Gary V. Vaughan <gary@gnu.org>
2804 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
2805 * config/Makefile.am: Removed. Automake 1.8 distributes the files
2806 in this directory automatically.
2807 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
2809 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
2811 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
2813 * modules/Makefile.am (pkglibexecdir): Set it here.
2814 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
2816 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
2817 Import regex module from CVS gnulib.
2818 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
2819 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
2820 do extra substitutions for Makefile.
2821 * configure.ac: Use it.
2822 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
2823 from regex_.h if necessary.
2824 * m4/system_.h: Include the correct version of regex.h.
2825 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
2827 * po/POTFILES.in: Use new location of regex.c.
2829 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
2830 realloc.c: automake distributes these files already.
2832 2003-09-12 Gary V. Vaughan <gary@gnu.org>
2834 Replace the xstrzdup code by importing the xstrndup module from
2835 CVS gnulib, along with its dependencies: strndup and strnlen:
2837 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
2838 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
2840 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
2841 gnulib/config/strndup.m4: Ditto wrt strndup.
2842 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
2844 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
2845 However, contrary to gnulib, we install xstrndup.h.
2846 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
2847 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
2848 is an artifact of the old m4 portability layer.
2849 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
2850 * m4/system_.h: Include xstrndup.h.
2851 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
2853 2003-09-11 Gary V. Vaughan <gary@gnu.org>
2855 Reimport the latest xalloc module from CVS gnulib, and adjust the
2856 m4 sources to take advantage of xalloc xfree. Also create a new
2857 macro DELETE with the same semantics as the old m4 XFREE macro,
2858 and carefully tweak callers:
2860 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
2862 * m4/utility.c (xfree): Removed. This function is now supplied by
2864 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
2865 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
2866 * m4/symtab.c (m4_symtab_create): Ditto.
2867 * m4/system_.h: Removed XFREE redefine.
2868 (DELETE): New macro with same functionality as the original m4
2869 XFREE macro, but based on xalloc.h now. Changed all callers.
2870 * src/main.c (main): Use XMALLOC macro.
2871 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
2873 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
2875 2003-09-10 Gary V. Vaughan <gary@gnu.org>
2877 Import the xalloc module from CVS gnulib, along with its
2878 dependencies: exitfail, malloc and realloc. We had different
2879 semantics for our XFREE and a function xfree() not supplied by
2880 gnulib, so also a bit of work to keep everything running
2883 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
2884 (gl_XALLOC): Use gnulib equivalents.
2885 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
2886 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
2887 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
2888 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
2890 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
2891 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
2892 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
2894 (pkgincdir): Removed. Use pkgincludedir instead.
2895 * m4/m4private.h (XFREE): xfree already checks for NULL.
2896 * m4/system_.h: Use xalloc module, and remove macros already
2897 supplied by xalloc.h.
2898 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
2899 moved the old definition from m4/xmalloc.c to here for now.
2901 2003-09-09 Gary V. Vaughan <gary@gnu.org>
2903 Import the error and progname modules from CVS gnulib. Our old
2904 error.c subsumed the functionality of both, so a little adjustment
2905 was required to accomodate the split in sources. Also added more
2906 wrapper macros to choose between a system installed error.h or our
2907 shipped gnulib error module:
2909 * m4/error.c, m4/error.h: Removed.
2910 * m4/Makefile.am: Adjust.
2911 (pkgincdir): Removed. Use pkgincludedir instead.
2912 * m4/module.h, src/main.c: Don't include `m4/error.h'.
2913 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
2915 * gnulib/m4/progname.c: Imported from CVS gnulib.
2916 * gnulib/m4/progname.h: Ditto.
2917 * src/main.c: Adjust to use progname module.
2918 * gnulib/m4/error.c: Imported from CVS gnulib.
2919 * gnulib/m4/error_.h: Ditto.
2920 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
2921 if appropriate, and link a local error.h if the system version is
2923 (libgnu_la_SOURCES) Add progname module sources.
2924 * gnulib/config/error.m4: Imported from CVS gnulib.
2925 * gnulib/config/strerror_r.m4: Ditto.
2926 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
2927 to have ERROR_H for Makefile substitutions and tell system.h
2928 whether the system error.h should be used, or a locally installed
2930 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
2932 2003-09-09 Gary V. Vaughan <gary@gnu.org>
2934 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
2935 s/gettext_.h/gettext.h/.
2937 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
2938 automake have been fixed.
2940 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
2941 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
2942 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
2943 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
2945 2003-09-09 Gary V. Vaughan <gary@gnu.org>
2947 The gnulib obstack module requires the gnulib gettext module for
2948 systems that do not have GNU gettext installed. Because we use
2949 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
2950 that directory incase it clashes with the system gettext.h. This
2951 delta uses gettext_.h and extra rules in the Makefile to make a
2952 link to gettext.h when needed:
2954 * Makefile.am (auxdir): Removed. No longer used.
2955 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
2956 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
2958 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
2959 Makefile based build.
2960 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
2961 of the macros are kept.
2962 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
2963 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
2964 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
2965 distributes these automatically.
2966 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
2967 warning from automake-1.7a.
2968 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
2969 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
2971 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
2972 wrt. m4_FUNC_OBSTACK.
2973 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
2974 wrt. m4_sys_STACKOVF.
2975 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
2976 wrt. _m4_LIB_GMP, m4_LIB_GMP.
2977 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
2978 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
2980 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
2981 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
2982 gettext.h link on deficient systems.
2983 (pkginc_HEADERS): Mention $(GETTEXT_H).
2984 (EXTRA_HEADERS): Mention gettext.h.
2985 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
2986 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
2987 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
2988 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
2989 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
2990 gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
2991 gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
2992 gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
2993 gnulib/config/po.m4, gnulib/config/progtest.m4,
2994 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
2995 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
2997 2003-09-05 Gary V. Vaughan <gary@gnu.org>
2999 We can't mirror the gnulib directory structure here, since we need
3000 to be able to eg. `#include <m4/obstack.h>' from our source files,
3001 which is much easier if the local obstack.h is created in a
3002 directory named m4. Rather than trying to symlink everything into
3003 the m4 directory, now we build a libtool convenience library from
3004 the sources we get from gnulib and link that with libm4.la:
3006 * gnulib/config/extensions.m4: Imported from CVS gnulib.
3007 * gnulib/config/unlocked-io.m4: Ditto.
3008 * gnulib/m4/unlocked-io.h: Ditto.
3009 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
3010 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
3011 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
3012 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
3013 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
3014 * m4/Makefile.am: Adjust.
3015 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
3016 macros we redistribute.
3017 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
3018 library among others.
3019 (GNULIB_SRCS, GNULIB_MACROS): Removed.
3020 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
3021 * config/m4-obstack.m4: Adjust.
3022 * po/POTFILES.in: Adjust.
3023 * configure.ac: Reformatting. Call newly imported gnulib macros.
3024 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
3025 bogus calls of `#include "m4.h"'.
3026 * Makefile.am: INCLUDES has been deprecated in favour of
3028 * m4/Makefile.am: Ditto.
3029 * modules/Makefile.am: Ditto.
3030 * src/Makefile.am: Ditto.
3032 2003-09-05 Gary V. Vaughan <gary@gnu.org>
3034 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
3036 2003-09-04 Gary V. Vaughan <gary@gnu.org>
3038 Migrate the obstack support into the gnulib directories for easy
3039 synchronisation with upstream files in gnulib:
3041 * config/gnu-obstack.m4: Moved from here...
3042 * config/m4-obstack.m4: ...to here.
3043 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
3044 * m4/obstack.c, m4/obstack_.h: Moved from here...
3045 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
3046 * po/POTFILES.in: Adjust.
3047 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
3048 * m4/Makefile.am: Add a whole new section to link the obstack
3049 sources from the gnulib tree if necessary.
3050 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
3052 * config/m4-obstack.m4: Rewrite as a wrapper for
3053 gnulib/m4/obstack.m4.
3055 2003-09-04 Gary V. Vaughan <gary@gnu.org>
3057 GNU M4 currently builds with a number of files adapted from
3058 upstream sources. Recently the gnulib project on savannah.gnu.org
3059 has pulled together a great many of these externally maintained
3060 files. This delta is the beginnings of isolating those files
3061 maintained in gnulib to make it easy to synchronise M4 with the
3062 upstream files prior to releases.
3064 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
3066 (SUBDIRS): Added new gnulib subdirectory.
3067 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
3068 * config/stdbool.m4: Moved from here...
3069 * gnulib/m4/stdbool.m4: ...to here.
3070 * m4/stdbool_.h: Moved from here...
3071 * gnulib/lib/stdbool_.h: ...to here.
3072 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
3074 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
3075 code to work with new stdbool_.h location.
3076 (gnulib_srcdir): New.
3078 2003-09-04 Gary V. Vaughan <gary@gnu.org>
3080 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
3081 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
3083 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
3084 (EXTRA_DIST): Use it.
3086 * bootstrap: CVS autoreconf leaves file droppings. Remove
3087 aclocal.m4t incase autoreconf doesn't.
3089 2003-08-29 Gary V. Vaughan <gary@gnu.org>
3091 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
3092 the other gnulib imports, renamed to m4/obstack_.h.
3093 * m4/obstack.c: Updated from CVS gnulib.
3094 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
3095 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
3096 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
3097 about vpath already, and $top_srcdir upsets CVS Automake, so the
3098 $top_srcdir reference was removed.
3100 * m4/system-h.in: For consistency with the gnulib imports, renamed
3102 * m4/Makefile (EXTRA_HEADERS): Adjust.
3103 * configure.ac (AC_CONFIG_FILES): Adjust.
3105 * m4/stdbool_.h: New file from gnulib for systems without their
3107 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
3108 * config/stdbool.m4: New file. Macros from gnulib for same.
3109 * configure.ac: Use it.
3111 2003-08-27 Gary V. Vaughan <gary@gnu.org>
3113 * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'`
3114 * config/gmp.m4: Ditto.
3115 * config/gnu-obstack.m4: Ditto.

3160 * src/main.c: Ditto.
3161 * src/stackovf.c: Ditto.
3163 * config/gmp.m4 (M4_AC_LIB_GMP): Use AC_INCLUDES_DEFAULT:
3164 ac_default_headers is an autoconf internal variable.
3165 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
3166 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
3168 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
3169 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
3172 2003-08-15 Gary V. Vaughan <gary@gnu.org>
3174 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
3176 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
3177 possible or faking one with a typedef. Changed all callers.
3179 2003-08-15 Gary V. Vaughan <gary@gnu.org>
3181 Still cleaning up the users' module API, by taking out the stuff
3182 that isn't used by any existing modules, and moving specialised
3183 functions out of libm4 and into the module they are used by.
3185 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
3186 * m4/utility.c (m4_skip_space): ...to here the home of its only
3187 use, made static and renamed to `skip_space'. Changed all
3189 * m4/m4module.h (m4_expand_ranges): Removed prototype.
3190 * m4/utility.c (m4_expand_ranges): Moved definition from here...
3191 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
3193 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
3195 * modules/gnu.c (builtin_syntax): Import and use in this
3196 builtin implementation.
3197 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
3199 * m4/macro.c (trace_flush): Except here where the macro is now
3201 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
3202 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
3204 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
3205 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
3207 2003-08-14 Gary V. Vaughan <gary@gnu.org>
3209 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
3210 compiler based AC_CHECK_HEADER that was introduced in
3212 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
3213 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
3214 * configure.ac: Use renamed M4_AC_LIB_GMP.
3216 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
3217 macro that requires arguments! This stops the shell's bad
3218 substitution error at configure time.
3220 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
3221 variables to the testsuite shell. Set the value of USE_GMP so
3222 that the gmp test will run!
3223 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
3225 2003-08-11 Gary V. Vaughan <gary@gnu.org>
3227 Libltdl already has an excellent mechanism for accessing C symbols
3228 in modules. Lets use that! Remove all the exporting cruft and
3229 just use lt_dlsym in conjunction with a few conventions to
3230 simplify module writers' jobs. Also removed the table address
3231 caching code and otherwise simplified the module loader quite a
3232 bit. To access exported symbols in other modules, first the
3233 exporting module must name the symbols <modname>_LTX_<symname>,
3234 and the importing module must define a function type called
3235 <symname>_func. The importer then adds
3236 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
3237 that wishes to call out to the exported functions. Care must be
3238 taken that <symname> is non-NULL in the importing module incase
3239 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
3240 definition was in the importers source. Study
3241 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
3242 m4_module_import will attempt to automatically load a module
3243 required for symbol access if it is not loaded already.
3245 * TODO: Removed the items fixed in this delta.
3246 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
3248 * m4/ltdl.h (lt_dlhandle_find): Declare it.
3249 * m4/module.c (m4_module_unload): Use it.
3250 * src/freeze.c (reload_frozen_state): Ditto.
3251 * m4/m4module.h (m4_export): Deleted. Removed all references.
3252 (M4_MODULE_IMPORT): New user convenience macro for importing
3253 arbitrary symbols from other modules.
3254 * m4/module.c (m4_module_import): New function to service
3255 M4_MODULE_IMPORT macro.
3256 (module_data): Removed. Looking up the tables on demand with
3257 lt_dlsym, rather than caching their addresses here simplifies the
3259 (m4_get_module_builtin_table, m4_get_module_macro_table):
3260 Removed. Changed all callers.
3261 (set_module_macro_table, set_module_builtin_table): Renamed to
3262 install_macro_table and install_builtin_table respectively, and
3263 simplified now that the cache is no more.
3264 * modules/gnu.c (builtin_symbols): Use this new mechanism to
3265 import m4_dump_symbols from the m4 module.
3266 (builtin_esyscmd): Likewise for m4_set_sysval and
3268 * modules/m4.c (m4_export_table): Removed. Functions are
3269 addressed with the new mechanism which doesn't need this.
3270 (m4_set_sysval): New exported accessor function to prevent
3271 problems with variable access on inferior architectures.
3272 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
3273 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
3274 that we can have some type safety.
3275 * modules/modtest.c (export_test): C level exported function for
3276 testing the new import mechanism.
3277 * modules/import.c: New file for the import end of the test.
3278 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
3279 * tests/modules.at: New test cases for intermodule symbol
3282 2003-08-07 Gary V. Vaughan <gary@gnu.org>
3284 * m4/m4module.c (m4_string): Moved from here...
3285 * m4/m4private.c (m4_string): ...to here.
3287 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
3289 2003-07-29 Gary V. Vaughan <gary@gnu.org>
3291 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
3292 already available to module writers through
3293 m4_{get,set}_nesting_limit_opt(), so moved from here...
3294 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
3295 (m4_create): Use it.
3297 2003-07-28 Gary V. Vaughan <gary@gnu.org>
3299 Aside from auditing path.c for m4module.h api obfuscation, this
3300 delta introduces the concept of private struct members in opaque
3301 data types to GNU m4: See the STYLE file for details.
3303 * TODO: Remind ourselves that a rewrite of path.c is needed.
3304 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
3306 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
3307 here and renamed. These type definitions are for internal api use
3308 only. Changed all callers.
3309 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
3311 * m4/path.c (search_path_env_init, search_path_add): ...to here
3312 and renamed. These calls were never used outside this file.
3313 Changed all callers.
3314 (dirpath): Moved functionality of this static declaration...
3315 * m4/m4private.h (struct m4): ...to this new internal only
3316 search_path field. Changed all callers.
3317 (m4__get_search_path): Added new internal api accessor.
3318 * m4/path.c (m4_search_path_info_new): Removed. Not used.
3319 (m4_include_init): Removed...
3320 * m4/m4.c (m4_create): ...because the new m4 field is now
3322 (m4_delete): Recycle search_path memory.
3323 * src/main.c (main): Don't call m4_include_init now that it's
3325 * doc/STYLE: Document convention for private fields in opaque
3328 2003-07-24 Gary V. Vaughan <gary@gnu.org>
3330 Sometimes exporting the address of a symbol from a module isn't
3331 enough for other modules to call that symbol correctly. If
3332 custom data types are used for function parameters, they need to
3333 be known to the caller. This change introduces the concept of
3334 $(prefix)/include/modules/$(modulename).h to declare those
3335 structures. Also we move m4_dump_symbols from libm4 to the m4
3336 module to show this concept in action.
3338 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
3339 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
3340 exporting data structures from modules/m4.c.
3341 * modules/m4.c, modules/gnu.c: Include it.
3342 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
3343 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
3345 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
3347 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
3348 ...to here, with slight renaming.
3349 (m4_export_table): Prototype and add m4_dump_symbols.
3350 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
3351 definition of m4_dump_symbols.
3352 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
3353 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
3355 2003-07-24 Gary V. Vaughan <gary@gnu.org>
3357 Create an export table in modules/m4.c in readiness for beefing up
3358 the module loader to track module exports and imports.
3360 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
3361 * m4/debug.c (m4_debug_flush_files): Moved...
3362 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
3363 * modules/gnu.c (builtin_esysval): Use it.
3364 * m4/m4module.h (m4_export): New type for declaring module symbols
3366 * modules/m4.c (m4_export_table): List symbols exported from this
3367 module for use by other modules.
3369 2003-07-24 Gary V. Vaughan <gary@gnu.org>
3371 An experiment: There is loads of code in libm4 which should be in
3372 the m4 module, but is also used by another module. Just because
3373 some linkers won't cope with calls across dynamic runtime loaded
3374 objects I initially left the code in libm4. It will tidy the
3375 module api immensely if this code moves to the right place, I just
3376 need to remember to invent a suitable calling mechanism at some
3377 point. For now, only modules that are statically linked and
3378 preloaded will get this treatment, so the only platforms that will
3379 break are those that require all symbols to be resolved at link
3382 * TODO: Reminder that what I am doing could reduce portability
3383 unless I do something more robust later.
3384 * m4/m4module.h (m4_sysval): No longer exported from libm4.
3385 * m4/utility.c (m4_sysval): No longer declared in libm4.
3386 * modules/Makefile.am: Reformatting.
3387 * modules/m4.c (m4_sysval): Declare it at place of use.
3388 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
3390 2003-07-23 Gary V. Vaughan <gary@gnu.org>
3392 * m4/m4module.h: Reformatting and rearranging lines a bit.
3393 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
3395 (m4_call_macro, m4_expand_input): Renamed...
3396 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
3398 (m4_expansion_level, m4_process_macro): Moved...
3399 * m4/macro.c (expansion_level, process_macro): ...to here, and
3402 * m4/m4module.h (program_name): Not used by modules at all, so
3404 * src/main.c (program_name): ...to here.
3405 (print_program_name): Renamed...
3406 (print_program_name_CB): ...to conform to the STYLE guide.
3408 2003-07-23 Gary V. Vaughan <gary@gnu.org>
3410 More refactoring of the m4module.h API. Replace #defines with an
3411 enum, and move non-public functions out of the public API.
3413 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
3415 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
3416 * m4/debug.c (m4_debug, trace): Moved...
3417 * m4/m4private.h (struct m4): ...to fields of this struct.
3418 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
3420 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
3421 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
3422 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
3423 * m4/m4module.h (m4_context_field_table): Add entries for new
3424 debug_file and trace_messages fields.
3425 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
3426 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
3427 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
3428 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
3429 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
3430 (m4_is_debug_bit): New macro to simplfy checks against the debug
3432 (m4_trace_format, m4_trace_header, m4_trace_flush)
3433 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
3435 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
3436 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
3437 * m4/macro.c (trace_format, trace_header, trace_flush)
3438 (trace_prepre, trace_pre, trace_post): ...to these newly static
3439 functions, since they are only ever used from this file. Changed
3442 2003-07-17 Gary V. Vaughan <gary@gnu.org>
3444 Change the macros for checking syntax so that matching against
3445 multiple possible syntax classes can be done with a single
3446 comparison some of the time. The various classes are now bits of
3447 an int that can be checked with bitwise logic operators.
3449 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
3450 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
3451 (M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)
3452 (M4_SYNTAX_ASSIGN, M4_SYNTAX_ALPHA, M4_SYNTAX_NUM)
3453 (M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)
3454 (M4_SYNTAX_ECOMM): Replaced #defines with an enum.
3455 (M4_SYNTAX_ALNUM): Removed. Changed all callers.
3456 (M4_IS_IGNORE, M4_IS_OTHER, M4_IS_SPACE, M4_IS_OPEN, M4_IS_CLOSE)
3457 (M4_IS_COMMA, M4_IS_DOLLAR, M4_IS_ACTIVE, M4_IS_ESCAPE)
3458 (M4_IS_ASSIGN, M4_IS_ALPHA, M4_IS_NUM, M4_IS_LQUOTE, M4_IS_RQUOTE)
3459 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
3460 Replace all calls with invocations of these...
3461 (m4_is_syntax, m4_has_syntax): ...New macros.
3462 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
3463 is no longer required with new macros. Changed all callers.
3465 2003-07-15 Gary V. Vaughan <gary@gnu.org>
3467 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
3468 values are returned as part of the internal interface, so they
3470 * m4/private.h: ...to here.
3471 * m4/macro.c (expand_token): Check for out of range
3472 m4_peek_input() results before looking up in the syntax table.
3473 (collect_arguments): Ditto.
3475 * NEWS: Note `$' syntax class.
3477 2003-07-08 Paul Eggert <eggert@twinsun.com> and
3478 Gary V. Vaughan <gary@gnu.org>
3480 Conform to POSIX if the POSIXLY_CORRECT environment is set.
3481 --traditional `define' now smashes all the definitions.
3483 * NEWS: Explain this.
3484 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
3485 (Extensions): Explain that extensions that are incompatible with
3486 POSIX are disabled if POSIXLY_CORRECT is set.
3487 (Incompatibilities): Remove.
3488 (Define, Other Incompat): Explain difference
3489 between GNU and POSIX behavior of define, pushdef, popdef.
3490 * m4/m4.c (m4_get_posixly_correct_opt): New undef.
3491 * m4/m4module.h (m4_context_opt_bit_table): Add POSIXLY_CORRECT entry.
3492 * m4/m4private.h (M4_OPT_POSIXLY_CORRECT_BIT): New macro.
3493 (m4_get_posixly_correct_opt): New macro.
3494 * m4/m4macro.c (m4_process_macro): Disable $10, $abc etc. if
3496 * modules/m4.c (builtin_functions): defn now takes any number of args.
3497 (builtin_define): Smash all the definitions if
3499 (builtin_defn)): Allow any number of arguments.
3500 (builtin_undivert): Do not allow nonnumeric arguments
3502 * src/main.c (main): Set posixly-correct behavior if either
3503 POSIXLY_CORRECT is set, or if -G is given.
3504 * tests/builtins.at: New test for smashed definitions.
3506 2003-06-27 Gary V. Vaughan <gary@gnu.org>
3508 * doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
3509 * m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
3510 not to slow the parser down.
3511 (M4__IS_STRING): New macro to test string syntax class membership.
3512 * m4/syntax.c: Adjust docucomment.
3513 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
3514 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
3515 * m4/input.c (init_builtin_token): Comment typo.
3516 (m4__next_token): Comment typo.
3517 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
3518 by using the new M4__IS_STRING macro.
3519 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
3520 variable references in macro expansions.
3522 * doc/m4.texinfo (Eregexp and Regexp): Typo.
3523 (Epatsubst and Patsubst): Typo.
3526 2003-06-26 Gary V. Vaughan <gary@gnu.org>
3528 Move the global variables that pertain to syntax to a new `struct
3529 m4_syntax_table', and then add one of these to `struct m4'. The
3530 ripple effect through the code to both change formerly global
3531 references, and make sure a suitable context is available in
3532 lexical scope is disproportionately large compared to the size of
3533 the change proper. This change is a large part of decoupling
3534 syntax.c from the rest of the code that uses it.
3536 * m4/m4private.h (struct m4): Add a syntax field.
3537 * m4/m4.c (m4_create): Initialise it,
3538 (m4_delete): Recycle it.
3539 (m4_get_symtab): Remove hand coded version...
3540 (m4_get_symbol_table): ...and generate this with cpp. Changed all
3542 * m4/m4module.h (m4_context_field_table): Add an extra field so we
3543 can generate m4_get_symbol_table. Add a new row for
3544 m4_get_syntax_table.
3545 (M4SYNTAX): Syntactic sugar for module writers.
3546 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
3547 (m4_syntax_table): New home for syntax related formerly global
3549 * m4/m4private.h (struct m4_syntax_table): Define it.
3550 * m4/input.c (m4_input_init): Initialisation of these formerly
3551 global variables moved...
3552 * m4/syntax.c (m4_syntax_create): ...to here.
3553 * m4/input.c (m4_input_exit): And similarly, recycling of the
3554 memory used by those values moved...
3555 * m4/syntax.c (m4_syntax_delete): ...to here.
3556 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
3557 Moved to m4/m4private.h.
3558 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
3559 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
3560 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
3561 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
3562 objects. Changed all callers that used to directly access the
3564 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
3565 Removed and incorporated into m4_syntax_table structure.
3566 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
3567 * m4/syntax.c (m4_set_syntax): Now returns an error status,
3568 instead of requiring a `struct m4' to generate its own errors.
3569 Changed all callers.
3570 * src/main.c (main): Now that the syntax table is initialised as
3571 part of m4_create, we have to manually wipe the syntax entries if
3572 we are about to read a frozen file.
3574 2003-06-26 Gary V. Vaughan <gary@gnu.org>
3576 * doc/STYLE: Added notes on callback naming schemes.
3578 * m4/module.c (m4_set_module_macro_table)
3579 (m4_set_module_builtin_table): Declarations weren't changed when
3580 definitions were renamed on 2003-06-19.
3582 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
3583 neither used nor particularly appropriate since it exposes the
3584 internal workings of the hash module. I haven't yet decided
3585 whether to remove it entirely.
3587 2003-06-20 Gary V. Vaughan <gary@gnu.org>
3589 Two related changes, and a huge knockon effect throughout the
3590 source: Moved the option variables out of global space and into
3591 `struct m4'; made `m4_symtab' a real datatype, so that its api
3592 is not marred passing `struct m4' around just so it can decide
3593 whether to keep traced symbol names or not. Added setters and
3594 getters for the formerly global option variables, and obviously
3595 changed a vast number of functions to take a `struct m4' and use
3596 the getter funcs to find option values.
3598 * m4/utility.c (interactive, sync_output, debug_level)
3599 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
3600 (max_debug_argument_length, warning_status, nesting_limit)
3601 (discard_comments): Removed.
3602 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
3603 (debug_level, max_debug_argument_length, prefix_all_builtins)
3604 (suppress_warnings, discard_comments, interactive, sync_output):
3605 Removed from here...
3606 * m4/m4private.h (struct m4): ...and equivalent fields added to
3608 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
3609 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
3610 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
3611 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
3612 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
3613 macros for the new fields.
3614 * m4/m4module.h (m4_context_field_table)
3615 (m4_context_opt_bit_table): Helper macros used to generate
3616 prototypes, setters and getters for new option fields
3618 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
3619 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
3620 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
3621 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
3622 (m4_get_interactive_opt, m4_get_sync_output_opt)
3623 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
3624 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
3625 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
3626 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
3627 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
3628 setter and getter functions generated by cpp from
3629 m4_context_field_table and m4_context_opt_bit_table, exported as
3630 part of the module api. Changed all callers.
3631 * m4/symtab (struct m4_symtab): Used as the concrete type for
3633 (m4_symtab_create): Allocate and initialise a new struct.
3634 (m4_symtab_apply): New function that works like m4_hash_apply, but
3635 with different callbacks specific to symbol tables. Changed all
3637 (symbol_destroy, arg_destroy, arg_copy): Renamed
3638 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
3639 they have unused parameters for a reason!
3640 (dump_symbol_CB): New callback to dump the contents of a single
3642 (symtob_dump): Rewritten in terms of dump_symbol_CB.
3643 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
3644 Changed all callers.
3645 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
3646 of the contained `m4_symtab' at the `no_gnu_extensions' field.
3647 Although I'm not convinced these semantics are correct, they are
3648 at least consistent with how things were before this delta. Also
3649 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
3651 2003-06-19 Gary V. Vaughan <gary@gnu.org>
3653 Tie down the interface to libm4 some more. Make more structures
3654 opaque to modules by moving them to m4private.h, and writing
3655 setters and getters. To win back the speed penalty for doing this
3656 also wrote macroized versions that do know about structure layout
3657 in m4private.h and #include that file into modules when NDEBUG is
3658 defined at compile time. There are still some accessor macros in
3659 m4private.h that need to go, but that is not necessary to clean
3662 * m4/m4module.h (m4_symbol_type): Moved...
3663 * m4/m4private.h (m4__symbol_type): ...to here.
3664 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
3665 (m4_set_symbol_traced, m4_set_symbol_name_traced)
3666 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
3667 (m4_get_symbol_func, m4_symbol_value_create)
3668 (m4_symbol_value_delete, m4_set_symbol_value_text)
3669 (m4_set_symbol_value_func): New exported api to symbols.
3670 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
3671 and m4_is_symbol_value_func.
3672 * m4/m4module.h: Prototype these guys.
3673 * m4/module.c (m4_set_module_macro_table)
3674 (m4_set_module_builtin_table): Make these static, there is no
3675 reason to pollute the api with them.
3676 * m4/m4private.h: Reformatting.
3677 (m4_get_symtab): Only define when NDEBUG is defined.
3678 (m4_get_symbol_value, m4_get_symbol_traced)
3679 (m4_set_symbol_traced, m4_set_symbol_name_traced)
3680 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
3681 (m4_get_symbol_func, m4_symbol_value_create)
3682 (m4_symbol_value_delete, m4_set_symbol_value_text)
3683 (m4_set_symbol_value_func): Macro implementations of the new
3684 functions when NDEBUG is defined.
3685 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
3686 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
3687 Superceded by the above. All callers changed.
3688 (M4ARG): Removed. This is no longer different to the
3689 m4/m4module.h definition.
3690 * modules/gnu.c, modules/m4.c: Only include m4private.h when
3691 NDEBUG is defined. That way we exercise the same (albeit slower)
3692 api that external modules must use.
3694 2003-06-18 Gary V. Vaughan <gary@gnu.org>
3696 Renamed some of the types and their accessors to make more sense.
3697 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
3698 has a stack of SYMBOL_VALUEs.
3700 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
3701 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
3702 m4_get_symbol_value_type, m4_get_symbol_value_text,
3703 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
3704 Changed all callers.
3705 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
3706 (m4_get_token_type): Renamed
3707 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
3708 to the internal api.
3709 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
3711 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
3712 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
3713 (m4__token_type): Moved here from m4module.h.
3714 (m4__next_token): Renamed from m4_next_token.
3715 * m4/symtab.c: Removed some of the parameterised macro support
3716 functions for modularisation later.
3717 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
3718 m4_hash_dup to perform a true deep copy of the SRC.
3719 (arg_copy): Callback for m4_symbol_value_copy.
3720 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
3721 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
3722 m4_get_symbol_value_func. Changed all callers.
3724 2003-06-18 Gary V. Vaughan <gary@gnu.org>
3726 Tidy up style of hash.[ch] in accordance with doc/STYLE.
3728 * m4/hash.c: Internal symbol renaming and formatting.
3729 (m4_hash_dup): New function to facilitate deep copies of hash
3731 (m4_hash_apply_func): Returns a void* now, which is a richer type
3732 for returning exceptions (NULL means keep going).
3733 (m4_hash_apply): Ditto.
3734 * m4/hash.h: Declare exported symbols with an explicit extern.
3737 2003-06-17 Gary V. Vaughan <gary@gnu.org>
3739 Still refactoring furiously. This delta represents a change in
3740 semantics to symtab.c. Instead of building temporary m4_tokens
3741 in the caller, and copying fields in the methods, we now create
3742 the actual m4_token for hashing in the caller so the methods just
3743 slot them in directly. Also, this means that we don't lookup a
3744 symbol and get back an allocated but VOID token to copy fields
3745 into, we create the token we want to push and pass that to
3746 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
3747 a few other small changes to stop knowledge of the implementation
3748 of symtab.c leaking out into other files.
3750 * m4/macro.c (expand_argument): Comment typo corrected.
3751 * m4/symtab.c (symtab_fetch): New function to fetch the address of
3753 (m4_symbol_pushdef): Take an extra value parameter and use this
3754 directly as the new top of the value stack. All callers changed
3755 to build a token and pass responsibility for memory in, rather
3756 than copying as we used to.
3757 (m4_symbol_define): Also use the new value parameter directly as a
3758 replacement for the top of the value stack. All callers changed
3759 to build a token as above.
3760 (m4_set_symbol_traced): New function to set the traced bit on the
3761 named symbol, creating it if necessary.
3762 (symbol_popval): The guts of the old m4_symbol_popdef.
3763 (m4_symbol_popdef): Use it.
3764 * m4/builtin.c (m4_symbol_set_token): Removed,
3765 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
3767 * m4/module.c (m4_set_module_builtin_table)
3768 (m4_set_module_macro_table): ...with these more orthogonal
3770 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
3771 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
3773 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
3774 (m4_arg_signature_parse): Moved...
3775 * m4/symtab.c: ...to here.
3776 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
3777 screw something up. Moved...
3778 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
3779 actually does a proper deep copy of source to dest.
3781 2003-06-16 Gary V. Vaughan <gary@gnu.org>
3783 Further refactoring to stabilise the module API. Renaming some
3784 functions for orthogonality, and judicious definition migration to
3785 move things out of the set of exported symbols.
3787 * doc/STYLE: New file. Notes on coding style.
3788 * m4/m4module.c: Updated bitrotted docucomment at the top of the
3790 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
3791 m4_get_module_name, m4_get_module_builtin_table,
3792 m4_get_module_macro_table which are verb phrases. Changed all
3794 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
3796 * m4/module.c (m4_set_module_builtin_table)
3797 (m4_set_module_macro_table): ...here, and renamed. Changed all
3799 * m4/m4module.c (m4_module_data): This...
3800 * m4/m4private.c (struct m4_module_data): ...and this...
3801 * m4/module.c (module_data) ...consolidated here and no longer
3802 exported. Changed all callers.
3804 2003-06-16 Gary V. Vaughan <gary@gnu.org>
3806 Begin work on lifting the curse of the global variables. To start
3807 with create a `struct m4' context container, and replace
3808 `m4__symtab' with `context->symtab' throughout. This means
3809 initialising a context container in main, and adjusting many
3810 functions between main and the module entry points so that the
3811 container gets passed through. It would have been nice to
3812 defer this until after 1.5, but it has a major effect on the
3813 user's module writing ABI, so it needs to be addressed now - at
3814 least in the areas that impact the ABI. An interrelated change
3815 in the symtab API removes the dependency on a global symbol table,
3816 and instead focuses on a passed table (from the context
3819 * TODO: Reminders for finishing context functionality.
3820 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
3821 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
3822 global variables and eventually allow m4 to be reentrant.
3823 * m4/m4private.h (m4): Define the new structure here...
3824 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
3825 don't carry the overhead of a function call.
3826 * m4/m4module.h: Prototype extern functions from m4/m4.c.
3827 (m4): Declare type for new struct m4 objects.
3828 (M4SYMTAB): User macro to ease finding the symbol table for the
3829 current context for module developers.
3830 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
3832 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
3833 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
3834 (m4_call_macro, m4_dump_symbols, m4_expand_input)
3835 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
3836 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
3837 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
3838 m4* context parameter. Changed definitions and all callers.
3839 (m4_symtab): Alias for m4_hash to decouple the
3840 m4_symtab api from m4_hash.
3841 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
3843 (m4_symtab_create): New function to return an initialised
3845 (m4_symtab_delete): New function to delete an m4_symtab's memory.
3846 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
3847 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
3848 instead of simply using the global m4__symtab. Changed
3849 definitions and all callers.
3850 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
3851 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
3852 * src/main.c (main): Create a context and use that instead of the
3853 former global m4__symtab.
3855 2003-06-13 Gary V. Vaughan <gary@gnu.org>
3857 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
3858 to the callback. Callbacks should not need to hardcode the
3859 hashtable they are working from, nor should we have to waste the
3860 userdata parameter to pass the table in.
3861 * m4/hash.h (m4_hash_apply_func): Require the initial table
3863 * m4/symtab.c (symtab_destroy): Use the passed table instead
3864 of hardcoding m4__symtab.
3865 (m4_symbol_popdef): Don't use the userdata parameter to pass the
3866 table to arg_destroy.
3867 (arg_destroy): Use the hash parameter, ignore userdata.
3868 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
3870 (traceon, traceoff): Call set_trace with the extra initial
3873 2003-06-13 Gary V. Vaughan <gary@gnu.org>
3875 More refactoring to stabilise the module api, this time for
3876 symtab.c. Additionally, start to pay attention to function names
3877 that don't contain a verb like they should.
3879 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
3880 wrapper for m4_hash_apply to decouple the symtab module from the
3882 (m4_symbol_builtin, m4_symbol_macro): Renamed to
3883 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
3885 (m4_symbol_delete): Create a macro version to save a function
3887 (m4_token_t, m4_data_t): These violate the POSIX reserved
3888 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
3890 (m4_token_type): Renamed to m4_token_get_type.
3891 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
3892 (m4_symtab_exit): Removed from the exported module
3894 * m4/m4private.h (m4__symtab, m4__symtab_init)
3895 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
3896 renamed and added to the internal api. Changed all callers.
3897 (m4_symtab_apply): A faster macro version of the function for
3898 users of the internal api.
3899 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
3900 symbol_destroy and arg_destroy.
3901 (symtab_debug): Added a prototype.
3902 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
3903 so that callers in this file get the faster macro versions from
3906 2003-06-12 Gary V. Vaughan <gary@gnu.org>
3908 Refactoring modules to rationalise the API into an external
3909 documented (eventually!) API for use by modules in the `m4_'
3910 namespace declared in m4/m4module.h, an internal API between the
3911 source files we ship (including our shipped modules) in the `m4__'
3912 namespace declared in m4/m4private.h and making the rest as
3913 cohesive as possible with liberal use of the `static' keyword.
3914 This change represents an audit to m4/module.c along these
3917 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
3918 Removed. No longer used.
3919 (m4_module_close): Removed prototypes.
3920 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
3921 from the exported module api...
3922 * m4/m4private.h (m4__module_init, m4__module_open)
3923 (m4__module_exit): ...and renamed and added to the internal api.
3924 Changed all callers.
3925 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
3926 Centralised definitions after renaming...
3927 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
3928 (M4_FINISH_SYMBOL): ...and removing from here.
3929 (m4_module_dlerror, m4_module_remove, m4_module_close)
3930 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
3931 module_remove, module_close and caller_id.
3932 (MODULE_SELF_NAME): New macro to make reporting self errors
3934 (m4_module_load, module_close, module_remove): Use it.
3935 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
3937 * src/main.c (main): Use it.
3939 2003-06-12 Gary V. Vaughan <gary@gnu.org>
3941 * README: Remove references to --enable-changeword, which has been
3942 removed from the code.
3944 2003-06-11 Gary V. Vaughan <gary@gnu.org>
3946 Getting rid of the annoying bug with configure --enable-debug,
3947 which spewed -e: command not found errors. This was an interaction
3948 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
3949 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
3950 branch-1-5) to get the full fix.
3952 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
3953 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
3954 and then use the probed value of $SED.
3955 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
3956 this, it messes up the AC_REQUIRE stack.
3958 2003-06-10 Gary V. Vaughan <gary@gnu.org>
3960 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
3961 the destroy callback.
3962 (m4_arg_destroy): Use the hash address to free the hash node key
3965 2003-06-06 Gary V. Vaughan <gary@gnu.org>
3967 First cut at formal parameters in macros.
3969 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
3970 * m4/xstrzdup.c: New file.
3971 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
3972 associative array of parameter names to details.
3973 (m4_symbol_token): Capture macro names with parameter lists.
3974 (m4_arg_signature_parse): And build an associative array to hang
3975 from the symbol structure to map names to details.
3976 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
3977 m4_hash_resize idiom. Now that we potentially add a little hash
3978 table to many of the entries in the symbol table, added an extra
3979 arg to set the initial size. Changed all callers.
3980 (m4_hash_apply): New function that is basically a generalised
3982 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
3983 all callers to call m4_hash_apply instead.
3984 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
3985 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
3986 m4_arg_signature association that might be attached to the symbol,
3987 * m4/hash.h (m4_hash_apply_func): Replacement type for...
3988 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
3989 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
3991 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
3992 (M4_IS_IDENT): Detect characters that can be safely used in
3994 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
3995 * m4/macro.c: Corrected grammar in some comments. Use `token'
3996 rather than `td' for m4_token variables.
3997 (m4_process_macro): If we find a dollar followed by some
3998 M4_IS_IDENT characters, replace that with the contents of the argv
3999 entry with offset stored in the m4_token_arg associated with the
4000 collected identifier.
4002 2003-06-05 Gary V. Vaughan <gary@gnu.org>
4004 Begin preparations for supporting formal parameters in m4 macros.
4006 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
4007 the details of a formal parameter.
4008 (m4_token): Add an arg_signature member to hold a hash table for
4009 looking up formal parameters.
4010 * m4/input.c: Update more bitrotted comments.
4011 (m4_push_builtin): Initialise arg_signature member.
4012 (init_builtin_token): Copy arg_signature member.
4013 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
4014 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
4016 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
4017 (m4_macro_pushdef, m4_macro_define): ...these, And...
4018 (m4_symbol_token): ...wrapped around this new function, which
4019 vastly simplifies the arguments required by the functions it
4021 Changed all callers.
4023 2003-06-05 Gary V. Vaughan <gary@gnu.org>
4025 * m4/macro.c: Format changes.
4027 2003-06-04 Gary V. Vaughan <gary@gnu.org>
4029 * m4/input.c: Updated various bitrotted comments.
4030 (m4_push_builtin): Just pass the whole m4_token, rather than
4031 extracting all the fields in the caller. This also allows us to
4032 check the token type for consistency.
4033 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
4034 Renamed to builtin_funcs, builtin_peek, builtin_read,
4035 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
4036 the code. Changed all callers.
4037 (struct input_block): Similarly renamed u_m member to u_b, and
4038 changed all callers.
4039 (m4_next_token): Use bzero to initialise the data fields.
4040 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
4042 2003-05-29 Gary V. Vaughan <gary@gnu.org>
4044 These changes were necessary to get m4 to build on my iBook
4045 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
4046 (GCC) 3.1 20020420 (prerelease)":
4048 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
4049 inclusion of module loader headers.
4050 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
4051 * m4/Makefile.am: Ditto.
4052 (libm4_la_LIBADD): Added $(LTLIBINTL).
4053 * m4/utility.c (program_name): Removed declaration in favour of
4054 the one already in error.c!
4055 * m4/m4module.h (program_name): Define to program_invocation_name
4056 when using GNU C library. Use an explicit extern declaration.

4069 * m4/error.h (error, error_at_line, error_print_progname)
4070 (error_message_count, error_one_per_line): Ditto.

4086 2002-11-04 Akim Demaille <akim@epita.fr>
4088 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
4090 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
4092 2002-11-04 Akim Demaille <akim@epita.fr>
4094 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
4096 2002-11-04 Akim Demaille <akim@epita.fr>
4098 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
4099 used as `external', and Libtool 1.4.3.
4101 (LTLIBOBJS): Don't play with it.
4103 * Makefile.am (SUBDIRS): Remove intl.
4104 (ACLOCAL_AMFLAGS): Add -I config.
4105 (EXTRA_DIST): Add config/config.rpath.
4108 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
4110 2002-05-29 Gary V. Vaughan <gary@gnu.org>
4112 Preparations for refactoring syntax tables to allow reverse
4113 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
4114 speed of normal lookups in an array of unsigned short.
4116 * m4/input.c (single_quotes, single_comments, use_macro_escape):
4118 * m4/m4private.h (m4__single_quotes, m4__single_comments,
4119 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
4120 is for internal symbols which unavoidably pollute the global
4121 namespace, but are not published APIs.
4122 Adjusted all callers.
4123 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
4124 m4_set_comment, m4_set_syntax, set_syntax_internal,
4125 unset_syntax_attribute): Moved from this file...
4126 * m4/syntax.c: New. ...to this file.
4127 Also added an m4_syntax_exit stub for orthogonality.
4128 * src/main.c (main): Use it.
4129 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
4130 * m4/m4module.h: Reformatting. New prototypes.
4132 2002-05-29 Gary V. Vaughan <gary@gnu.org>
4134 * bootstrap (aclocal_apiversion): The aclocal apiversion is
4135 distinct from the automake release number (in that the apiversion
4136 apparently has no micro-version-component).
4137 (aclocal_apilibdir): Use it.
4139 2002-05-28 Gary V. Vaughan <gary@gnu.org>
4141 * m4/hash.c (m4_hash_resize): New function.
4142 * m4/hash.h: Add prototype.
4143 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
4144 benchmarking to find a good value for, say, autoconf. This is
4145 already a little quicker than before for me.
4147 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
4148 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
4150 * m4/hash.h: Adjust prototypes.
4152 2002-01-22 Akim Demaille <akim@epita.fr>
4154 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
4156 * tests/Makefile.am (package.m4): New.
4157 * tests/atlocal.in: Adjust to CVS Autotest.
4158 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
4159 * configure.ac: LIBOBJ is a forbidden string.
4160 Simplify AM_INIT_AUTOMAKE invocation.
4161 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
4164 2002-01-21 gettextize <bug-gnu-utils@gnu.org>
4166 * po/Makefile.in.in: Upgrade to gettext-0.10.40.
4168 2001-10-19 Akim Demaille <akim@epita.fr>
4170 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
4172 2001-10-19 Akim Demaille <akim@epita.fr>
4174 * m4/input.c (m4_next_token): Display where was opened what is

4182 2001-10-18 Akim Demaille <akim@epita.fr>
4184 * m4/input.c, modules/m4.c: Formatting changes.
4186 2001-10-17 Gary V. Vaughan <gary@gnu.org>
4188 * bootstrap: s/configure.in/configure.ac/
4190 2001-10-16 Gary V. Vaughan <gary@gnu.org>
4192 * m4/symtab.c (m4_symbol_destroy): This function calls
4193 m4_symbol_popdef, which recycles a symbols memory when the last
4194 definition is popped. Since we were passing the address of the
4195 symbol name found in the symbol table, and it was being removed
4196 partway through m4_symbol_destroy() we were referencing freed
4197 memory for the balance of the function. Now we take a copy of the
4198 symbol name tring and use that as a key into the symbol
4199 table... that way if the original symbol name is freed, the copy
4202 2001-10-13 Akim Demaille <akim@epita.fr>
4204 * m4/ltdl.c: Update.
4206 2001-10-13 Akim Demaille <akim@epita.fr>
4208 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
4209 Don't gettextize internal error messages.
4211 2001-10-13 Akim Demaille <akim@epita.fr>
4213 * tests/macros.at (Arity and defn): New failing test.
4214 (Arity, defn, and freeze): New.
4216 Fix `Arity and defn'.
4218 * m4/input.c (m4_push_macro): Don't forget the arity.
4219 * modules/m4.c (defn): Likewise.
4221 2001-10-13 Akim Demaille <akim@epita.fr>
4223 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
4225 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
4226 (Propagation of traceon, Propagation of --trace): this new file.
4228 2001-10-13 Akim Demaille <akim@epita.fr>
4230 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
4231 interface instead of (name, argc...).
4232 Upon failure, specify which argument was guilty.
4235 2001-10-13 Akim Demaille <akim@epita.fr>
4237 * modules/evalparse.c: Save translators' time: don't translate
4238 internal error messages.
4239 (m4_evaluate): Simplify/normalize error messages.
4240 * doc/m4.texinfo (Eval): Adjust.
4242 2001-10-13 Akim Demaille <akim@epita.fr>
4244 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
4245 where no checking is needed.
4246 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
4247 interface instead of (name, argc...).
4249 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
4252 2001-10-13 Akim Demaille <akim@epita.fr>
4254 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
4255 exclude the builtin name from the count.
4256 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
4257 calling ifelse with a single argument is valid.
4258 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
4259 with 1 and 2 args, mostly to strengthen the test suite.
4261 2001-10-13 Akim Demaille <akim@epita.fr>
4263 * m4/output.c (m4_make_diversion, m4_insert_file)
4264 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
4266 2001-10-12 Gary V. Vaughan <gary@gnu.org>
4268 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
4269 since we call these things builtins in the rest of the code!
4271 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
4273 2001-10-12 Gary V. Vaughan <gary@gnu.org>
4275 Rather than forcing each builtin definition to manage its own
4276 argument range checking, tabulate the maxima and minima for all
4277 builtins in each module. This forces us to consider what the
4278 valid ranges for each builtin should be, and moves the checking
4279 code out of each builtin implementation and into the builtin
4280 caller infrastructure.
4282 * m4/m4module.h (struct m4_builtin): Add argument minima and
4284 * m4/m4private.h (struct m4_token): Reflect them here too.
4285 * m4/input.c (struct input_block): ...and here.
4286 (m4_token_copy): New function for token copying.
4287 (init_macro_token): Copy them from a token to the input stack.
4288 (m4_next_token): Don't forget to initialise them for text
4290 * m4/macro.c (expand_argument): Use m4_token_copy, and also
4291 check argument counts before calling the builtin handler.
4292 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
4293 (m4_symbol_macro): Likewise.
4294 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
4295 parameters. Updated all callers.
4296 (m4_builtin_define): Ditto.
4297 (m4_macro_pushdef, m4_macro_define): Ditto.
4298 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
4299 * modules/evalparse.c: Declare argument counts for defined
4300 builtins and remove explicit calls to m4_bad_argc().
4301 * modules/gnu.c: Ditto.
4302 * modules/load.c: Ditto.
4303 * modules/m4.c: Ditto.
4304 * modules/modtest.c: Ditto.
4305 * modules/mpeval.c: Ditto.
4306 * modules/perl.c: Ditto.
4307 * modules/shadow.c: Ditto.
4308 * modules/stdlib.c: Ditto.
4309 * modules/time.c: Ditto.
4312 2001-10-10 Gary V. Vaughan <gary@gnu.org>
4314 The trace semantics now attach the trace bit to a symbol name.
4315 For as long as a traceon(`foo') is active, calls to foo will be
4316 traced regardless of intervening undefines or module unloads.
4317 Fixed the flag propogation issues differently to the fixes
4318 reverted with the last attempt at nailing down trace:
4320 * m4/m4private.h: This file is not visible outside of the m4
4321 source tree, so I removed all the `M4_' and `m4_' prefixes to save
4322 on typing. Updated all clients.
4323 (m4_token): New typedef contains the fields that need to be passed
4324 around with the low level tokeniser.
4325 (m4_token_data): Removed.
4326 (m4_symbol): Now contains the traced flag again.
4327 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
4328 the trace bit set. This change is contained entirely within this
4329 module and doesn't leak out into the callers. Updated all
4331 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
4332 new fields in m4_token. Updated all clients.
4333 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
4334 that `groks_macro_args' and `blind_if_no_args' flags are retained
4335 when defn() results are passed around in m4 code. Updated all
4337 (m4_builtin_define): Ditto.
4338 (m4_macro_pushdef, m4_macro_define): Ditto.
4339 * m4/input.c (struct input_block): Add a flags field to facilitate
4341 (m4_push_macro): ...use it.
4342 (init_macro_token): Retrieve it.
4343 (m4_next_token): Initialise it.
4344 * m4/macro.c (expand_argument): Copy it.
4345 * m4/m4module.h: Adjust.
4346 * tests/builtins.at: Adjust the expected output of the trace
4347 tests to reflect the change in semantics.
4348 * tests/modules.at (modules: trace): Check that unloading a
4349 module which supplies a traced symbol definition doesn't lose te
4352 2001-10-07 Gary V. Vaughan <gary@gnu.org>
4354 * modules/gnu.c (m4_macro_table): Display the timetamp when
4355 expanding __m4_version__.
4357 * configure.ac (--with-modules): Forgot a comma in the
4358 AC_HELP_STRING parameter list.
4360 2001-10-05 Gary V. Vaughan <gary@gnu.org>
4362 * bootstrap: Remove aclocal.m4t when it is no longer required.
4364 2001-10-05 Akim Demaille <akim@epita.fr>
4366 * tests/Makefile.am: Adjust for gnuprog2.
4367 * tests/m4.in: There can be a leading path.
4368 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
4369 * tests/testsuite.at: Adjust to the most recent Autotest.
4370 (AT_CHECK_M4_FILTER): Fix and rename as...
4372 * tests/others.at: Use it.
4374 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
4375 variable in shell scripts, one uses `$'...
4377 2001-10-04 Gary V. Vaughan <gary@gnu.org>
4379 * configure.ac: `rm -f $m4_getopt_h' was lost.
4381 2001-10-04 Gary V. Vaughan <gary@gnu.org>
4383 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
4384 time. Define it for config.h in order to...
4385 * src/main.c (main): ...display the timestamp for --version.
4387 2001-10-04 Akim Demaille <akim@epita.fr>
4389 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
4390 previous builtins `regexp' and `patsubst'.
4391 (regexp, patsubst): Use them.
4392 (eregexp, epatsubst): New builtins.
4393 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
4394 (Epatsubst and Patsubst, Eregexp and Regexp): these.
4395 (Extensions): More info on REs.
4397 2001-10-04 Akim Demaille <akim@epita.fr>
4399 * modules/modtest.c (init_handler): Consistently output to stderr.
4400 (finish_handler): New.
4401 (test): The `if' is an `assert'.
4402 * tests/modules.at: Adjust.
4404 2001-10-04 Akim Demaille <akim@epita.fr>
4406 * m4/utility.c (m4_bad_argc): Detail the mismatches.
4408 2001-10-01 Akim Demaille <akim@epita.fr>
4410 * tests/generate.awk: Tag the tests with `documentation'.
4411 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
4412 Use the make the existing modtest tests more uniform, and complete
4413 the set of possibilities.
4415 2001-10-01 Akim Demaille <akim@epita.fr>
4417 * config/gmp.m4: Consult the user before using GMP: use
4419 * configure.ac: Adjust.
4420 * modules/gmp.c: No protection needed as the module is not built
4423 2001-10-01 Akim Demaille <akim@epita.fr>
4425 * tests/generate.awk: Remove debugging code.
4426 (fatal): Specify the current location.
4428 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
4429 * modules/gnu.c, modules/m4.c: Use M4ARG.
4431 2001-10-01 Akim Demaille <akim@epita.fr>
4433 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
4434 (m4_regexp_compile): New.
4435 (regexp, patsubst): Use it.
4437 2001-09-30 Gary V. Vaughan <gary@gnu.org>
4439 Reinstate the memory handling improvements from the patch I just
4440 reverted. Relevant ChangeLog entries repeated here:
4442 * m4/module.c (m4_module_remove): New function that holds the core
4443 of the old m4_module_unload.
4444 (m4_module_unload): Use it.
4445 (m4_module_unload_all): When we know the modules will never be
4446 used again (i.e. on exit), free up as much module memory as
4447 possible. There are still some artifacts from resident modules
4448 living inside ltdl.c, but everything else is freed.
4449 * m4/debug.c (m4_debug_exit): Free memory allocated in
4451 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
4452 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
4453 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
4454 * m4/m4module.h: Updated prototypes.
4455 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
4456 * m4/hash.h: Updated prototypes.
4457 * src/main.c (main): Use all these new functions to clean up as
4458 much memory as possible before exit.
4460 2001-09-30 Gary V. Vaughan <gary@gnu.org>
4462 Reverted my large patch for removing the old m4_symbol
4463 structure on 2001-09-20. We are still not happy about the way
4464 trace works in conjunction with defn and undefine, and leaving
4465 the reverted patch active prevents us from moving the traced
4466 bit from the definition back to the symbol.
4468 2001-09-30 Gary V. Vaughan <gary@gnu.org>
4470 * configure.in: Moved to...
4471 * configure.ac: ...here. Added a libtool like timestamped
4472 banner, and tidied up the libltdl cruft.
4473 * config/mkstamp: Script to extract a timestamp from ChangeLog.
4474 * modules/Makefile.am (INCLTDL): Removed. This is required
4475 only when libltdl is configured in a subdirectory.
4476 * src/Makefile.am: Ditto.
4477 (LIBADD_DL): No need to add this again, libtool already knows
4478 that libm4.la depends on it.
4479 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
4482 * TODO: stackovf.c is basically broken.
4483 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
4485 2001-09-28 Akim Demaille <akim@epita.fr>
4487 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
4489 2001-09-27 Akim Demaille <akim@epita.fr>
4491 * tests/m4.in: Don't use short options.
4492 Simplify the stderr signature normalization.
4494 2001-09-27 Akim Demaille <akim@epita.fr>
4496 tests/m4 shall be position independent.
4500 * tests/testsuite.at: No args to AT_INIT.
4501 * configure.in, tests/Makefile.am: Adjust.
4503 2001-09-22 Akim Demaille <akim@epita.fr>
4505 Autotest has changed again.
4507 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
4508 (package.m4): Remove.
4509 * configure.in: Adjust to LIBADD_GMP.
4511 2001-09-21 Gary V. Vaughan <gary@gnu.org>
4513 * config/gmp.m4 (AC_ARG_WITH): Removed.
4514 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
4515 (AC_LIB_GMP): When performing a test compile against libgmp,
4516 include the header gmp.h if possible, and link against -lgmp. If
4517 they both work define USE_GMP.
4518 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
4519 (mpeval_LTX_init_func): Complain on load that there was no libgmp
4522 2001-09-20 Gary V. Vaughan <gary@gnu.org>
4524 * m4/evalparse.c: Moved to...
4525 * modules/evalparse.c: ...here. This code is shared between
4526 modules/mpeval.c and modules/m4.c, so there is no need to pollute
4527 the libm4 API with its details. Moderately rewritten to interface
4528 into its clients more simply.
4529 * m4/eval.c: Deleted. Migrated functionality to...
4530 * modules/m4.c: ...here.
4531 (builtin_eval): Implemented in terms of the new interface style.
4532 * modules/mpeval.c (builtin_mpeval): Ditto.
4533 * m4/m4module.h: Removed references to the former m4/eval.c.
4534 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
4535 (EXTRA_libm4_la_SOURCES): Deleted.
4536 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
4537 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
4539 2001-09-20 Akim Demaille <akim@epita.fr>
4541 * config/gmp.m4 (AM_WITH_GMP): Rename as...
4543 By default, use gmp.
4545 * configure.in: Adjust.
4546 Use Automake conditionals for USE_GMP.
4547 Always compute sizeof (long long int).
4548 This was a bug BTW, as `eval' (not `mpeval') depends on it:
4549 before, it was used _only_ if mpeval was not activated.
4550 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
4551 (mpeval_la_LIBADD): New macros.
4552 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
4554 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
4555 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
4558 2001-09-20 Akim Demaille <akim@epita.fr>
4560 * tests/Makefile.am (package.m4): New.
4561 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
4563 2001-09-20 Gary V. Vaughan <gary@gnu.org>
4565 More cleanup. After the last patch, m4_symbol holds nothing but
4566 the head of a chain of m4_token_data. So I have removed the old
4567 m4_symbol, so that m4_token_data chains are stored directly in the
4568 value cell of a hash table node. But there's more... m4_symbol
4569 was a more natural name for the symbol value cell, and now that it
4570 is gone I have renamed the former m4_token_data structure to
4571 m4_symbol. This change turned out to be a pig to get right, since
4572 the original code didn't need to modify the value cell itself,
4573 since changing the chain happened inside the m4_symbol that used
4574 to be returned -- I had to pass the address of the value cell
4575 across various function calls, incase the head value changed. I
4576 also tightened up the memory management to help me find a nasty
4577 memory corruption bug that took me all night to track down...
4579 * m4/m4private.h (struct m4_symbol): Removed.
4580 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
4582 * m4/hash.c (m4_hash_iterator_value): Return the address of the
4583 value cell. Updated all callers.
4584 * m4/symtab.c: Took advantage of the simplification in the data
4585 structures to rewrite a lot of this file more simply. There is
4586 still some room for optimisation here, but we should tackle that
4587 systematically closer to the release.
4589 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
4590 revealed. This version is ahead of CVS libtool until I get chance
4591 to flush my changes.
4592 * m4/module.c (m4_module_remove): New function that holds the core
4593 of the old m4_module_unload.
4594 (m4_module_unload): Use it.
4595 (m4_module_unload_all): When we know the modules will never be
4596 used again (i.e. on exit), free up as much module memory as
4597 possible. There are still some artifacts from resident modules
4598 living inside ltdl.c, but everything else is freed.
4599 * m4/debug.c (m4_debug_exit): Free memory allocated in
4601 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
4602 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
4603 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
4604 * m4/m4module.h: Updated prototypes.
4605 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
4606 * m4/hash.h: Updated prototypes.
4607 * src/main.c (main): Use all these new functions to clean up as
4608 much memory as possible before exit.
4610 2001-09-18 Gary V. Vaughan <gary@gnu.org>
4612 The `traced' flag needs to be attached to the definition of a
4613 symbol rather than the current symbol containing the definition.
4614 Implementing this showed up some long standing post 1.4 bugs in
4615 flag propogation which I also fixed.
4617 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
4618 (struct m4_token_data): And add it back in here.
4619 * m4/input.c (init_macro_token): Propogate the traced flag
4621 * m4/macro.c (expand_argument): Ditto.
4622 * tests/builtins.at (trace2, trace3): New tests based on Akim's
4625 2001-09-08 Gary V. Vaughan <gary@gnu.org>
4627 * m4/m4private.h (struct m4_token_data): Simplified by removing
4628 the redundant `traced' flag, and one level of structure nesting.
4629 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
4630 * m4/input.c (init_macro_token): No need to initialise removed
4632 * m4/macro.c (expand_argument): No need to copy it either.
4633 * m4/utility.c (m4_token_data_func_traced): Or provide an access
4636 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
4637 dependant on multiple symbols with the same key, so preserving
4638 relative symbol order in each bucket during resizing is no longer
4639 required. The resize function is considerably faster as a result.
4641 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
4642 s/m4_symbol_insert/m4_symbol_define/g;
4643 s/m4_builtin_insert/m4_builtin_define/g;
4644 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
4646 2001-09-08 Gary V. Vaughan <gary@gnu.org>
4648 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
4649 commits, the m4_lookup_symbol dispatch function is split into
4650 specialised functions that must be called directly.
4652 * m4/m4module.h (m4_symbol_lookup_t): Removed.
4653 * m4/symtab.c (m4_lookup_symbol): Removed.
4654 (m4_symbol_builtin, m4_symbol_macro): New functions.
4655 * m4/builtin.c (m4_builtin_define): Split into...
4656 (m4_builtin_pushdef, m4_builtin_insert): ...these.
4657 (m4_macro_define): Split into...
4658 (m4_macro_pushdef, m4_macro_insert): ...these.
4659 * src/main.c (main): Set command line macros from `-D' parameters
4660 using `m4_macro_define'.
4662 2001-09-08 Gary V. Vaughan <gary@gnu.org>
4664 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
4665 this from m4_remove_table_reference_symbols().
4666 * m4/m4module.h, m4/module.c: Updated all references.
4668 2001-09-07 Akim Demaille <akim@epita.fr>
4670 * modules/stdlib.c, modules/times.c: Misc cleanups.
4672 2001-09-07 Akim Demaille <akim@epita.fr>
4674 * configure.in: We now need Autoconf 2.52e.
4675 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
4676 and `M4_SYMBOL_DELETE'.
4677 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
4678 * src/main.c (main): Adjust.
4680 2001-09-06 Gary V. Vaughan <gary@gnu.org>
4682 Fix the obstack.h problem once and for all! At configure time we
4683 can test for a system supplied obstack.h: depending on the
4684 result, we now generate system.h with an #include of the correct
4685 header. As a bonus, I've also added a --with-included-obstack,
4686 incase the user doesn't like the system obstack for some
4687 reason... and also we can test the shipped obstack on a system
4688 that has oe of its own. We also now need to be careful to add
4689 build directories to the include search path, since the generated
4690 system.h will be in the build tree.
4692 * configure.in (AC_CONFIG_FILES): Generate system.h from
4694 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
4695 include the system obstack header or the copy shipped with M4.
4696 Allow the user to override configure and force the build to use
4697 the shipped version.
4698 * m4/system-h.in: New file, template for...
4699 * m4/system.h: ...this. Now deleted.
4700 * m4/m4module.h: Include system.h before everything else.
4701 * src/freeze.c: Ditto.
4702 * m4/Makefile.am (dist-hook): Remove generated system.h.
4703 (INCLUDES): Check builddir for generated headers before checking
4705 * modules/Makefile.am (INCLUDES): Ditto.
4706 * src/Makefile.am (INCLUDES): Ditto.
4708 2001-09-05 Gary V. Vaughan <gary@gnu.org>
4710 * TODO: Remove the items that have been addressed already.
4712 2001-09-05 Akim Demaille <akim@epita.fr>
4714 * src/main.c (main): Standardize --version.
4716 2001-09-05 Akim Demaille <akim@epita.fr>
4718 * modules/format.c (format): Have a bigger `str'.
4720 2001-09-05 Akim Demaille <akim@epita.fr>
4722 Rationalize warnings, reporting the macro name as if it were a
4723 program name, and assertions.
4725 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
4727 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
4729 Use assert for internal errors.
4730 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
4732 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
4734 * tests/builtins.at (pushpop): Adjust.
4736 2001-09-05 Akim Demaille <akim@epita.fr>
4738 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
4741 2001-09-05 Akim Demaille <akim@epita.fr>
4743 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
4744 * m4/macro.c, m4/symtab.c: Adjust.
4746 2001-09-05 Akim Demaille <akim@epita.fr>
4748 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
4749 (m4_symbol_pop, m4_symbol_del): this.
4750 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
4751 (m4_symbol_popdef, m4_symbol_delete): New.
4752 (m4_lookup_symbol): Adjust.
4753 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
4755 2001-09-05 Akim Demaille <akim@epita.fr>
4757 * m4/m4module.h (m4_symbol_lookup): Rename as...
4758 (m4_symbol_lookup_t): this.
4760 2001-09-05 Akim Demaille <akim@epita.fr>
4762 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
4764 * m4/symtab.c (m4_lookup_symbol): Adjust.
4766 2001-09-03 Gary V. Vaughan <gary@gnu.org>
4768 Bootstrap will now work with Libtool 1.4.1 or higher:
4769 * bootstrap: Remove stale autom4te.cache files when
4771 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
4773 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
4774 libtool.m4 directly.
4775 Run libtoolize to refresh ltmain.sh.
4776 * config/ltmain.sh: Deleted.
4777 * acinclude.m4: Deleted.
4778 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
4780 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
4781 implementation for the cvs impaired libtool user.
4783 2001-09-03 Akim Demaille <akim@epita.fr>
4785 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
4787 Avoid using `default' in switch, as it hides useful compiler
4788 warnings when a case is forgotten.
4790 2001-09-03 Akim Demaille <akim@epita.fr>
4792 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
4793 is no such thing as `WITH_MODULES'.
4795 2001-09-03 Akim Demaille <akim@epita.fr>
4797 Improve the test suite's selfcontainedness.
4799 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
4800 (Include, Undivert): Tag the other input files.
4801 * tests/generate.awk: Catch `@comment file:'.
4802 `-I $src' is no longer needed.
4803 `next' is really like `return': the rest is skipped.
4804 Adjust to `input.m4'.
4805 (fatal): New function.
4806 * tests/foo, tests/incl.m4: Remove.
4808 2001-09-01 Gary V. Vaughan <gary@gnu.org>
4810 The shadowing mechanism and, infact, the whole symbol table
4811 implementation was creaking under the weight of the features piled
4812 on top of it. We now have a separate hash table module which will
4813 dynamically resize to keep symbol density withing good performace
4814 limits, and a new symtab module layered above it. Symbol lookups
4815 are now marginally more efficient (since the shadowed flag is no
4816 longer required) and symbol removal, such as on module unload, is
4817 considerably faster due to a reorganisation of the data structures
4820 * src/main.c (main): Don't mention `-H'.
4821 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
4824 * m4/hash.c: New generalised dynamic hash table data structure
4826 * m4/hash.h: Public interface.
4827 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
4828 (libm4_la_SOURCES): Add hash.c.
4829 * m4/symtab.c: More or less rewritten from scratch, within the
4830 bounds of the previous API.
4831 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
4832 call. Updated all callers.
4833 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
4834 declarations to reflect API changes.
4835 (M4INIT): Generate a declaration too, to avoid the warning with
4836 --enable-debug builds.
4839 * m4/utility.c (hash_table_size): Removed.
4840 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
4841 names, which are then looked up by builtin_dumpdef() as necessary.
4842 This implies a small speedup in builtin_symbols(), which discarded
4843 all of the symbol info under the old call.
4844 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
4845 shadowing is implicit in respect to the new data structures.
4846 symbol names are no longer duplicated here, they are stored in the
4847 key field of the hash table.
4848 Moved macro_args and blind_no_args...
4849 (m4_token_data): ...to here.
4850 m4/macro.c (expand_macro): Added a name argument since the symbol
4851 name is no longer copied into each struct m4_symbol. Modified all
4853 (collect_arguments): Ditto.
4854 * modules/m4.c (set_trace): Ditto.
4855 * modules/gnu.c (builtin_symbols): Updated.
4856 * src/freeze.c (produce_symbol_dump): Much improved in light of
4857 the improved symbol table layout.
4859 2001-09-01 Gary V. Vaughan <gary@gnu.org>
4861 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
4863 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
4864 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
4865 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
4866 SYMBOL_HANDLE): Ditto.
4867 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
4868 modules/gnu.c, modules/m4.c, src/freeze.c,
4869 src/main.c: Updated all references.
4871 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
4872 Automake 1.5 chokes on dynamic source file lists, Besides, it is
4873 already listed in m4_LDADD... how did that ever used to work?
4874 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
4876 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
4877 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
4879 * tests/m4: Don't call the m4 wrapper script with libtool, it
4880 works fine all by itself.
4882 2001-08-30 Gary V. Vaughan <gary@gnu.org>
4884 The experimental `changeword' feature never took off, and has
4885 no obvious advantages over `changesyntax' to compensate the
4886 enormous speed penalty it carries:
4887 * configure.in (ENABLE_CHANGEWORD): Removed.
4888 * m4/m4module.h (m4_set_word_regexp): Removed.
4889 * m4/m4private.h (m4_token_data): Removed original_text field.
4890 * m4/utility.c (m4_token_data_orig_text): Removed.
4891 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
4892 * m4/macro.c: Ditto.
4893 * src/main.c: Ditto.
4894 * modules/Makefile.am (changeword.la): Removed.
4895 * modules/changeword.c: File removed.
4896 * doc/m4.texinfo: References to changeword and --word-regexp
4898 * po/POTFILES.in: modules/changeword.c removed.
4899 * tests/atlocal.in (ENABLE_CHANGEWORD): Removed.
4900 * tests/builtins.at (changeword): Test removed.
4902 2001-08-30 Akim Demaille <akim@epita.fr>
4904 * bootstrap.sh: Create aclocal.m4 instead of modifying it.
4905 This also help having a single list of m4 files: in
4907 * config/Makefile.am (STANDARD_MACROS): Rename as...
4908 (ACLOCAL_MACROS): this.
4909 (list-standard-macros): Remove.
4912 2001-08-29 Gary V. Vaughan <gary@gnu.org>
4914 In an attempt to moderate my egomania...
4915 * tests/modules.at: Remove attributions.
4917 * tests/generate.awk: When making substitutions to "@&t@", either
4918 "&" or "\&" in the substitution string argument to gsub refer back
4919 to the matched text. "@\\&t@" seems to work though, Tests 43 and
4922 2001-08-29 Akim Demaille <akim@epita.fr>
4924 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)
4925 (include, indir, multiquotes, patsubst, pushdef/popdef, regexp)
4926 (sync-lines, trace, translit, undivert, wrap): Move to...
4927 * tests/builtins.at: this new file.
4928 * tests/others.at (Discard comments, import-environment): Move to...
4929 * tests/options.at: this new file.
4931 2001-08-29 Akim Demaille <akim@epita.fr>
4933 * tests/others.at (Freezing modules)
4934 (--module-directory: absolute path, modpath2, modpath3)
4935 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
4936 * tests/modules.at: here, new file.
4937 * tests/others.at, tests/generate.awk: Add a banner.
4938 * tests/testsuite.at: Adjust.
4939 (AT_CHECK_M4_FILTER): New, but unused.
4941 2001-08-29 Akim Demaille <akim@epita.fr>
4943 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
4945 * tests/others.at (wrap): Inline wrap.m4.
4946 (shadow): Inline shadow.m4.
4947 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
4948 * tests/m4: Simplify.
4950 2001-08-29 Akim Demaille <akim@epita.fr>
4952 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
4955 2001-08-29 Akim Demaille <akim@epita.fr>
4957 * tests/generate.awk (normalize): s/@__@/@&t@/.
4959 2001-08-28 Akim Demaille <akim@epita.fr>
4961 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.
4963 2001-08-28 Gary V. Vaughan <gary@gnu.org>
4965 * bootstrap (generate.awk): Generate test cases with new script.
4967 2001-08-27 Akim Demaille <akim@epita.fr>
4969 * tests/Makefile.am (installcheck-local): Don't use
4970 `dc_install_base' which is not visible here, but `exec_prefix'
4971 which is clearly the RT anyway.
4972 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
4973 related to testing a now installed m4.
4974 * tests/m4: Do it here.
4976 2001-08-27 Akim Demaille <akim@epita.fr>
4978 * tests/others.at (indir): Formatting change.
4980 2001-08-27 Akim Demaille <akim@epita.fr>

4983 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
4985 Prefer options over envvars.
4986 * src/main.c (main): First bug caught by the test suite (yeah!):
4987 --batch lacked a `break' which resulted in an accidental
4988 invocation of --discard-comments.
4990 2001-08-27 Akim Demaille <akim@epita.fr>
4992 * tests/others.at (capitalize, changeword, comments, ddivert)
4993 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
4994 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
4995 (sysv-args, trace, translit, undivert): Don't rely on files in
4996 examples/: AT_DATA them.
4998 2001-08-27 Akim Demaille <akim@epita.fr>
5000 Let the test suite use a wrapper around the not installed m4 to
5001 pretend it is (installed).
5003 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
5004 such a way that m4 does not process them.
5005 * configure.in: The package name seems to be `m4', not `M4'.
5007 * tests/atlocal.in (at_package, M4): Remove.
5008 * tests/testsuite.at, tests/others.at: Use m4, not $M4.
5010 2001-08-27 Akim Demaille <akim@epita.fr>
5012 * tests/Makefile.am (CLEANFILES): Remove.
5013 (DISTCLEANFILES, clean-local): New.
5014 * examples/mktests.sh: Remove.
5016 2001-08-27 Akim Demaille <akim@epita.fr>
5018 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
5019 Don't use aclocal: it's written by hand.
5020 * aclocal.m4: m4_include all the files instead of being built by
5022 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
5023 until it reads the traces by itself.
5024 * configure.in: Require Autoconf 2.42c as we are now using
5025 AC_CONFIG_TESTDIR instead of AT_CONFIG.
5026 Catch unexpanded `jm_' macros.
5027 * config/atconfig.m4: Remove.
5028 * config/error.m4: new.
5029 * config/Makefile.am: Ship the files included by aclocal.m4.
5030 * tests/Makefile.am (TESTSUITE_SOURCES): Rename as...

5038 (dist_man_mans): this.
5040 2001-08-20 Gary V. Vaughan <gary@gnu.org>
5042 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
5043 Robert Collins, building on Cygwin no longer requires Windows
5044 import and export symbol decorations.
5045 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.
5046 * m4/error.h (M4_SCOPE) [cygwin*]: Ditto.

5061 Ansify the source. Previously we had a mix, where my code was
5062 in a K&R compatible style, and the preexisting code was in ANSI
5063 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
5064 and now the code base is much cleaner.

5107 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
5108 * modules/m4.c (undivert): Disable the possibility of undiverting
5109 several files at once: it is not documented, it is inconsistent
5110 with the other macros, it can be straightforwardly mocked by
5111 several invocations, and most importantly, it prevents the
5112 possibility of other kinds of extension.
5113 Use `m4_numeric_arg'.
5115 2001-08-20 Akim Demaille <akim@epita.fr>
5117 * examples/include.m4: Typo.
5118 * tests/generate.awk: Really add it.

5123 2001-08-20 Akim Demaille <akim@epita.fr>
5125 Use sprintf, not ecft and friends since it is standard, portable,
5126 simplifies the code, and since the latter is even deprecated
5127 according to the GNU libc documentation.

5131 2001-08-19 Gary V. Vaughan <gary@gnu.org>

5275 Drop Autoconf 2.13 compatibility.
5277 * configure.in (changeword): No need to undefine it, as anyway if
5278 it's defined, M4sugar moved it as m4_changeword.

5280 (m4_pattern_allow): As it exists in 2.50, just use it.
5281 (AC_OUTPUT): Split in AC_CONFIG_FILES and AC_CONFIG_COMMANDS.

5336 (M4FINISH_HANDLER): And similarly for finish functions.
5337 * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER
5338 -- Add indirection to the CONC macro so that arguments are
5340 * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
5341 * modules/shadow.c (m4_init_module): Ditto.

5353 instead of the old module argument.
5354 (m4_builtin_table_install): Ditto.
5355 * modules/load.c (m4_resident_module): Removed. This is no
5356 longer implemented as a magic symbol...

5376 module association does not belong with the symbol...
5377 * m4/input.c (struct m4_builtin): ...it belongs with the builtin

5396 (CDPATH) Neutralize.
5397 * tests/gethem: Use them.
5399 2001-08-14 Gary V. Vaughan <gary@gnu.org>

5416 shell variable m4_cv_func_obstack_h.

5418 script and m4 binary by using $srcdir.

5421 optargs to the existing libltdl search path.
5422 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.

5429 * src/main.c (main): Add `-b' (for `batch') mode switch to force
5430 interactive mode off.

5434 * configure.in: Require Autoconf 2.52.
5435 (AC_ARG_PROGRAM): Remove, handled by Automake.

5440 * config/gnu-obstack.m4: Require Autoconf 2.52.
5441 (M4_AC_FUNC_OBSTACK): Rename `m4_obstack' and `m4_obstack_h'.

5499 feature to mark modules as resident if they export
5500 `m4_resident_module' as TRUE.
5501 (m4_module_unload): Do not remove resident modules, and take care
5502 with symbol insertion and deletion with resident modules.

5567 Move the implementation of GMP support for the mpeval() builtin
5568 into a loadable module that depends on libgmp. mpeval() and
5569 eval() share a common parser, now in m4/evalparser.c; the code
5570 in m4/numb.c and m4/numb.h is now physically split between
5571 m4/eval.c (the eval() backend) and modules/mpeval.c (the
5572 mpeval() backend), rather than being differentiated by cpp
5573 macros and multiple inclusion. The mpeval module is always
5574 built but will generate an diagnostic if it is used from an
5575 installation that didn't link in the gmp library.
5576 * modules/Makefile.am: build and install the new mpeval module.
5577 * modules/mpeval.c: Now contains the former parts of m4/numb.c
5578 and m4/numb.h that are required for gmp support in mpeval().
5579 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
5580 * m4/evalmp.c: Removed.
5581 * m4/m4module.h: Removed conditional prototype for
5583 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
5584 and m4/numb.h that do not rely on gmp.
5585 * m4/evalparse.c: New file, contains the shared parts of the
5586 eval() and evalmp() parser implementations, and is no longer
5587 unencumbered by cpp magic to uncover the right parts.
5588 * m4/numb.h: Removed. It's former contents are split between
5589 m4/eval.c and modules/mpeval.c.
5592 * tests/other-tests/changeword.test: New test. Rudimentary
5593 testing of changeword builtin runs only if --wnable-changeword
5594 was used at configure time.
5595 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
5596 alternation correctly. Split into two expressions to compensate.
5597 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
5598 * modules/Makefile.am: Build changeword module.
5599 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
5600 only when --enable-changeword was passed to configure.
5601 (builtin_changeword): If --enable-changeword was not used, then
5602 report that changeword() builtin has no support in m4 binary.
5604 2000-11-28 Gary V. Vaughan <gary@gnu.org>
5606 * src/main.c (main): Fixed a particularly nasty bug is
5607 user_search_path setting -- the -M flag processing must be
5608 extremely careful with search path ordering, or else the default
5609 installed module directory (possibly containing modules from a
5610 previous release) is placed earlier in the search path than any -M
5611 arguments (which are relied upon to load uninstalled modules with
5612 most of the tests in the regresion suite).
5614 * modules/load.c (builtin_load): Nasty hack to prevent adding
5615 symbols to symtab again if a module is loaded more than once.
5616 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
5618 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
5619 possible NULL pointer dereference.
5621 * m4/module.c (m4_module_find_by_modname): Renamed from
5622 m4_module_modname_find. Fixed all references.
5623 (m4_module_find_by_builtin): New function.
5625 * modules/modfreeze.test: load the `load' module with each
5627 * src/freeze.c (produce_frozen_state): Simplified in light of
5628 module field in m4_symbol. Allow a third argument for text macros
5629 to name the originating module.
5630 (reload_frozen_state): ditto.
5631 * m4/m4module.h: Fixup prototypes.
5632 * m4/builtin.h (m4_builtin_define): Add a module argument so
5633 that symbols can be registered against the defining module.
5634 (m4_macro_define): ditto.
5635 * m4/m4private.h (m4_symbol): Make the module field const to save
5636 on casting in the rest of the code.
5637 (SYMBOL_MODULE): New macro.
5639 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
5640 symbol reference maintenance bugs when removing a symbol from the
5643 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
5645 2000-11-27 Gary V. Vaughan <gary@gnu.org>
5647 * configure.in (m4_cv_func_obstack): A better check for whether
5648 libc has an obstack implementation.
5649 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
5651 * configure.in (--with-modules): Changed semantics. This
5652 option is now used to list modules to be preopened.
5653 * src/m4.h: #include "ltdl.h" unconditionally.
5654 * src/main.c: Removed all dependencies on WITH_MODULES.
5655 * src/freeze.c: ditto.
5656 * modules/Makefile.am: ditto.
5657 * m4/m4.c (builtin_m4exit): ditto.
5658 * modules/modpath1.test: ditto.
5659 * modules/modpath2.test: ditto.
5660 * modules/modpath3.test: ditto.
5661 * modules/modpath4.test: ditto.
5662 * modules/modtest.test: ditto.
5663 * modules/shadow.test: ditto.
5664 * modules/unload.test: ditto.
5666 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
5667 comes up on demand in LTLIBOBJS now.
5668 * configure.in (getopt_long): Creating and relying on a link for
5669 getopt.h on hosts with no getopt_long() of thier own works
5670 correctly now. This is necessary so that callers of getopt_long()
5671 can simply `#include <getopt.h>': the naive way of doing this
5672 would end up using our own getopt.h and the installed
5673 getopt_long(), which is asking for trouble!
5674 (obstack_init): A similar argument applies to obstack.h and
5677 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
5678 On Solaris-2.5 (at least) the native dlopen implementation
5679 gets confused about m4.o when looking for module "m4". This
5680 version always looks for .la an .$lib_ext suffixed names first
5681 to work around the problem. Sigh.
5683 * po/POTFILES.in: Take account of these file movements.
5684 * src/Makefile.am (m4_SOURCES): removed eval.c.
5685 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
5686 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
5687 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
5688 * modules/m4.c (builtin_eval): Use m4_evaluate().
5689 * m4/eval.c: Moved here from src/eval.c to facilitate
5690 implementation of eval() builtin as part of the `m4' loadable
5692 (m4_evaluate): renamed from evaluate for namespace cleanliness.
5693 * m4/numb.c: Moved here from src/numb.c, since it is #included
5694 into eval.c at compile time.
5695 * m4/m4module.h (m4_evaluate): Added prototype.
5696 * src/m4.h (evaluate): Removed prototype.
5698 2000-11-25 Gary V. Vaughan <gary@gnu.org>
5700 * modules/perl.c (builtin_perleval): Use PL_na for
5701 compatibility with perl-5.6.
5703 * src/main.c (main): It is now safe to
5704 ``m4_module_install("m4")'', without tripping over the m4
5706 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
5707 versions having fixed the insidious module search order bug.
5709 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
5710 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
5712 * configure.in: Figure out whether to use the installed
5713 getopt.h or the supplied one.
5714 * src/Makefile.am: ditto.
5716 * po/POTFILES.in: List files in their new positions.
5718 * config/ltmain.sh: This needs to be checked in to match the
5719 libtool macros copied to acinclude.m4 (until a released
5720 libtool copes with m4's needs).
5721 * bootstrap: Run gettextize.
5723 2000-11-24 Gary V. Vaughan <gary@gnu.org>
5725 * AUTHORS: Added my details.
5728 * bootstrap: temporary update until released libtool catches up.
5730 * All files: Use new GNU GPL copyright blurb with current contact

5764 * modules/gnu.c: New file implementing a new loadable module wuth
5765 definitions for all the gnu extension builtins.
5766 * modules/format.c: Moved here from src/format.c. Now included
5769 * src/main.c (main): Load the traditional module if m4 was
5770 started in `no_gnu_extensions' mode.
5771 * modules/traditional.c: New file implementing the ``unix'' macro,
5772 required when m4 is executed in traditional mode, as a loadable
5775 * src/main.c: Renamed from m4.c to avoid confusion with
5777 (main): Always load the m4 module.
5778 * modules/m4.c: New file implementing a new loadable module with
5779 definitions for all m4 builtins that are not gnu extensions.

5790 * m4/symtab.c: ditto.
5791 * m4/debug.c: ditto.

5793 * m4/output.c: ditto.
5795 * m4/ltdl.h, m4/ltdl.c: ditto.
5796 * m4/utility.c: Odd functions moved here from files in the src
5797 directory to facilitate builtin migration.
5799 2000-08-12 Gary V. Vaughan <gary@gnu.org>
5801 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
5802 error message, to make translators' jobs a little easier.

5804 (builtin_traceon): ditto.
5805 (builtin_traceoff): ditto.
5806 Reported by Akim Demaille <akim@epita.fr>

5832 makeinfo calculates them for us, and to make any future
5833 reorganisation easier.
5834 (Frozen files): Document format version 2.
5835 `V' now takes argument `2'.
5836 `F' can take a single argument if symbol and builtin names
5837 are the same, or 3 arguments if the builtin is from a module.
5838 New `S' specification for saving syntax table contents.

5975 * src/m4.c (main): Assume interactive mode if STDIN is connected

5980 * src/builtin.c: Much improved macro definition style.
5981 * src/m4private.h: Internal structures for m4_builtin and

5993 odule defines an identical name.
5994 * src/symtab.c (remove_table_reference_symbols): remove all symbol
5995 table entries which refer to a given builtin table.

6020 before calling lt_dlinit!, fix warnings
6022 2000-01-18 Gary V. Vaughan <gary@gnu.org>

6048 * acm4/ltdl.m4: Updated to latest from libtool cvs.
6049 * acm4/modules.m4: Remove code which duplicates ltdl.m4 and
6050 increment serial number.
6052 * Makefile.am (SUBDIRS): Moved @MODULES_DIR@ to compile before
6053 src dir and immediately after libm4 is built for confidence that
6054 it doesn't rely on the src directory.
6055 (SUBDIRS): Moved doc dir to the end since helptoman.pl and
6056 makeinfo stop the build on cygwin (because they don't work).
6058 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
6060 * m4/m4private.h: ...is not a public header, so moved to src.
6061 Add `#include <config.h>', `#define _COMPILING_M4' and
6063 * m4/Makefile.am (noinst_HEADERS): remove m4private.h.
6064 * src/Makefile.am (noinst_HEADERS): add m4private.h.

6083 * m4/Makefile.am (CLEANFILES): @EXEEXT@ left libtool wrapper behind.
6084 (INCLUDES): Look first in $(top_srcdir) (for eg. <m4/error.h>),
6085 and then in $(top_srcdir)/lib (for eg. "m4private.h").
6086 * src/Makefile.am (m4_LDADD): replace libi/libm4.la with
6088 * m4/m4error.h: Renamed error.h, for installation to
6089 $prefix/include/m4..

6104 From Akim Demaille <akim@epita.fr>
6106 2000-01-17 Gary V. Vaughan <gary@gnu.org>
6108 * src/ltdl.c: Use access() to abort doomed module load attempts
6109 if module file does not exist.
6111 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
6112 getopt1.o will already be used if appropriate, so I moved getopt.c
6113 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
6115 * modules/modpath1.test: Use correct filename in header line.
6116 * modules/modpath2.test: ditto.
6117 * modules/modpath3.test: ditto.
6118 * modules/modpath4.test: ditto.
6120 Without these changes lt_dlopen("test") attempts to
6121 LoadLibrary("/bin/test") on Windows, which although harmless
6122 generates a spurious error message which spoils most of the tests:
6123 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
6124 (TESTS): s/test.test /modtest.test /
6125 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /
6126 (test_la_SOURCES, test_la_LDFLAGS): renamed to use modtest.
6127 * modules/modpath1.test: s/test.m4 /modtest.m4 /
6128 * modules/modpath2.test: ditto.
6129 * modules/modpath4.test: ditto.
6130 * modules/modpath3.test: s/-m test /-m modtest /
6131 * modules/shadow.m4: use {un,}loadmodule(`modtest').
6133 2000-01-16 Gary V. Vaughan <gary@gnu.org>
6135 * src/ltdl.c (find_file): Updated to new version with fixed memory
6136 allocation bug in `next'.

6139 * modules/Makefile.am: Cleaned up and reordered.
6141 2000-01-16 René Seindal <rene@seindal.dk>
6143 * modules/Makefile.am (TESTS): New tests for the module system.
6145 * modules/*.test: New files.
6147 * src/m4.c (main): Added call to module_init().
6148 Treats -M and -m as the arguments -D -U and -t, ie deferred.
6150 * src/m4.h: Added declaration of module_init().
6152 * src/module.c (module_init): No longer static
6154 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
6155 Added to shut up automake about non standard libtool library
6158 * src/module.c: Disabled DEBUG by default.
6160 * modules/README: Changed example from unload.m4 to shadow.m4
6162 * modules/shadow.m4: Renamed from unload.m4
6164 * modules/Makefile.am (EXTRA_DIST): Removed unload.m4.
6166 * src/m4.c (main): Functionality for -m and -M were reversed.
6169 2000-01-12 Gary V. Vaughan <gary@gnu.org>
6171 * doc/help2man.pl: updated to version 1.020.
6173 * lib/COPYING.LIB: updated to version 2.1.
6175 * lib/m4module.h: restructure the M4_SCOPE code to work when
6176 creating a dll which links with libm4.la and both DLL_EXPORT
6177 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
6180 2000-01-11 Gary V. Vaughan <gary@gnu.org>
6182 Merged the following changes from my tree:
6184 1999-06-15 Gary V. Vaughan <gary@gnu.org>
6186 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
6187 ported to compile shared libs.
6189 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
6190 use `__declspec(dllimport)' when linking libm4.la on win32.
6191 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
6193 * configure.in (M4OBJS): Discover whether we need the shipped
6194 implementation of getopt_long.
6195 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
6196 main binary here, as opposed to the module library in lib/libm4.la.
6198 1999-06-14 Gary V. Vaughan <gary@gnu.org>
6200 * modules/README: Updated to describe the improved libltdl based
6202 * README (cygwin): Added some compilation notes for building m4
6203 correctly under cygwin.
6204 * TODO: Cleaned out the entries for the module system since they
6205 are now implemented.
6207 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
6208 all instances of __P with M4_PARAMS.
6210 * lib/getdate.h: removed unreferenced file.
6212 * lib/m4private.h: New file to define the private interface to the
6213 token_data struct, which must be shared between m4module.c, and
6214 builtin.c but not exported to modules built from the installed
6215 m4module.h since it's size changes depending on compile time
6218 * src/m4.h: Lots of stuff moved to lib/m4module.h.
6220 * lib/m4module.h: New file to define the interface available when
6221 compiling m4 modules.
6222 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
6223 necessary for module compilation into this new file.
6225 * lib/Makefile.am (include_HEADERS): install headers (renamed to
6226 avoid nameclash with other system headers) necessary for compiling
6228 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
6229 so that modules can include the (renamed) installed headers and
6230 be guaranteed a matching implementation.
6231 * lib/m4error.h: renamed from error.h.
6232 * lib/m4obstack.h: renamed from obstack.h.
6233 * lib/m4regex.h: renamed from regex.h.
6234 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
6235 implementation, simply include the shipped version
6236 unconditionally, otherwise it is hard for a module to know
6237 whether the m4obstack.h header it is using matches the
6238 implementation it ends up linking against.
6239 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
6242 1999-05-18 Gary V. Vaughan <gary@gnu.org>
6244 * examples/misc.test: Don't run this test on machines which don't
6245 have a root user in /etc/passwd (e.g. cygwin).
6247 * tests/get-them (/^@example$/): Error messages might have a
6248 ``.exe'' suffix to the program name, or else use the libtool
6249 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
6250 of these cases are now catered for when comparing error messages
6252 * tests/other-tests/*.test: ditto.
6253 * examples/*.test: ditto.
6255 * tests/defs (M4): use libtool execute mode.
6256 * examples/defs (M4): ditto.
6258 * tests/get-them (END): explicitly close any open file.
6259 (printthem): In a regular expression, '{' is the start of a repeat
6260 count! Use `[{]' for a literal open brace.
6261 (/^@node /): Don't use substr on a string shorter than the trim
6264 1999-05-17 Gary V. Vaughan <gary@gnu.org>
6266 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
6268 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
6270 2000-01-10 Andreas Schwab <schwab@suse.de>
6272 * tests/other-tests/gmp.test: Find config.sh in build directory.
6274 * configure.in: Find tests/mkconfig.sh in $srcdir.
6276 * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in
6277 <signal.h> (for SUS2 compliant systems).

6282 2000-01-10 René Seindal <rene@seindal.dk>
6286 * TODO, NEWS: Cleaned up and updated.
6288 * src/m4.c (main): New variable exit_status for exit status in
6289 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
6290 file cannot be read instead of EXIT_SUCCESS.
6292 * src/builtin.c (m4_indir): Changed error message to help
6293 translators (from Akim Demaille <demaille@inf.enst.fr>).
6295 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
6298 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
6301 * src/input.c (match_input): Reordering of code, to avoid multiple
6302 calls to push_string_init() from obstack_grow(), which can happen
6303 with some compilers (found and fixed by James Bonfield
6304 <jkb@mrc-lmb.cam.ac.uk>).
6306 * src/stackovf.c: Added prototypes for ultrix.
6307 (setup_stackovf_trap): Added __P to cast.
6308 (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>)
6310 2000-01-09 René Seindal <rene@seindal.dk>
6312 * doc/m4.texinfo (Changequote): Added comment about changing
6313 quotes when the old quote is a part of the new.
6315 * src/builtin.c (expand_ranges): Added break after trailing dash.
6316 This caused misbehavious on some systems (found and fixed by Akim
6317 Demaille <demaille@inf.enst.fr>).
6319 * AUTHORS: Thomas Tanner included
6321 * acconfig.h: Added entry for ss_sp (see below).
6323 * configure.in (use_stackovf): Added check for stack_t with member
6324 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert
6325 <eggert@twinsun.com>).
6327 * doc/m4.texinfo (Frozen files): Added a simpler example for
6328 generating frozen files from several input files.
6330 1999-11-14 Paul Eggert <eggert@twinsun.com>
6332 * po/POTFILES.in: Add lib/getopt.c, lib/obstack.c,
6333 lib/regex.c, lib/xmalloc.c.
6335 1999-11-10 René Seindal <rene@seindal.dk>
6337 * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal.
6339 * src/module.c: reindented.
6340 (module_load): return if this is a repeated load of same module.
6341 (module_init): slight change of logic to avoid repeated
6342 initialisation debug messages.
6344 * Makefile.am (DIST_SUBDIRS): Added to ensure modules/ is included
6345 in the distribution.
6347 * modules/Makefile.am (test_la_LDFLAGS): set to -module to silence
6348 automake warnings about missing lib prefix.
6349 (time_la_LDFLAGS): ditto
6350 (stdlib_la_LDFLAGS): ditto
6352 1999-11-10 Paul Eggert <eggert@twinsun.com>
6354 * src/m4.h: Include error.h, since our macros use error.
6355 * src/m4.c: Don't need to include error.h.
6357 1999-11-09 Paul Eggert <eggert@twinsun.com>
6359 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
6360 and zero, as Solaris 7 cc does.
6361 (bcopy): Remove macro; no longer needed with new obstack.h.
6363 * src/output.c (freeze_diversions): Don't assume that a
6364 diversion size can fit in `int'. Check for diversion file
6365 size too large to be printed with `unsigned long'.
6367 * src/Makefile.am (CFLAGS): Omit -Wall.
6369 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.
6371 * src/debug.c (trace_format):

6397 * src/module.c: entirely new implementation using libltdl.
6398 * po/POTFILES.in: added src/module.c.
6399 * modules/Makefile.am (LTLIBRARIES): Removed lib prefix as these
6400 are modules, not linktime libraries.
6401 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
6402 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
6403 avoidance on exported symbols.
6404 * modules/test.c (m4_macro_table, m4_init_module,
6405 m4_finish_module): ditto.
6406 * modules/time.c (m4_macro_table): ditto.
6408 * modules/time2.m4: new file which requires command line loading
6410 * src/m4.c (--load-module): dynamically load named runtime module
6411 into running executable before reading the source.
6412 (--module-directory): prepend a directory to the module search
6414 (module_init()): Do this the first time we load a module instead;
6415 if the module subsystem is broken normal m4 scripts can still run.
6416 * src/m4.h (install_builtin_table): is now exported.
6418 1999-03-26 Gary V. Vaughan <gary@gnu.org>
6420 * src/module.c: removed. No longer required.

6431 * src/Makefile.am (MAINTAINERCLEANFILES): ditto.
6432 * tests/Makefile.am (MAINTAINERCLEANFILES): ditto.
6434 * acinclude.m4: removed. `aclocal -I acm4' handles this much
6436 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
6437 * acm4/gettext.m4: removed. It causes a multiple definition vs.
6438 the installed gettext.m4 file when running aclocal.
6440 1999-03-25 Gary V. Vaughan <gary@gnu.org>
6442 * configure.in (AM_INIT_AUTOMAKE): bumped version number to
6443 distinguish this from the last prerelease.
6444 (AC_LIBLTDL_CONVENIENCE): build libltdl as a convenience library
6445 in its own subdirectory.
6447 * modules/Makefile.am (*_SOURCES): renamed to use libtool's "no
6448 lib prefix on a module" feature.
6449 (LDFLAGS): Added `-module -avoid-version' flags to build
6450 versionless module libraries.
6451 * src/builtin.c (m4_load_module): use libltdl.
6452 (module_unload_all): use libltdl.
6453 * src/m4.c (module_init): initialise module loading on demand for
6454 better diagnostics, and so that m4 will still work even if
6455 the module code is broken.
6456 * src/m4.h (module_init): removed. No longer relevant.
6457 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on
6458 exported symbols for compatibility with dlpreopening.
6459 * modules/test.c (m4_macro_table, m4_init_module,
6460 m4_finish_module): ditto.
6461 * modules/time.c (m4_macro_table): ditto.
6463 * bootstrap: New file. Runs all the autoutils in the right order
6464 after a fresh checkout, or a make maintainer-clean.
6466 1999-02-18 Akim Demaille <demaille@inf.enst.fr>
6468 * src/builtin.c (dump_symbols): New function, factoring common
6469 content of m4_dumpdef and m4_symbols.
6470 (m4_dumpdef): Use it.
6471 (m4_symbols): New function, implementing `symbols'. Use it.
6472 * doc/m4.texinfo: Fixed missing commas after @xref, so that the
6473 file compile with modern makeinfo.
6474 (Symbols): New node, documenting symbols.
6475 (direntry): Modernize.
6477 1998-12-11 René Seindal <rene@seindal.dk>
6479 * src/builtin.c (predefined_tab): New predefined macros
6480 __m4_changeword__, __m4_gmp__ and __m4_modules__ for testing for
6481 configure time options.
6483 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
6485 * src/module.c (module_try_load): Don't try to be clever and
6486 overwrite argument string. Instead allocate all constructed
6487 strings locally, since they can have arbitrary lengths. Make
6488 arguments pointers to const.
6489 (module_search): Simplify due to above change.
6491 1998-11-29 René Seindal <rene@seindal.dk>
6495 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): New tests.
6497 * tests/other-tests/import-environment.{m4,test}: New test.

6503 * src/m4.c (main): New option -c --discard-comments.
6504 New global variable discard_comments.
6506 * src/m4.h (token_type): New TOKEN_NONE for tokens to be
6507 discarded, ie never returned from next_token().
6508 Added declaration of discard_comments.
6510 * src/input.c (next_token): Now loops until token type is not
6511 TOKEN_NONE. Comments are now given this type when comments should
6514 * doc/m4.texinfo (Invoking m4): Updated for --import-environment
6517 1998-11-28 René Seindal <rene@seindal.dk>
6519 * src/m4.c (main): New option --import-environment (no single
6522 * When configured with --with-gmp both the normal (fast) eval()
6523 and the gmp aware mpeval() are defined. To restore previous
6524 bahaviour use "define(`eval', defn(`mpeval'))".
6526 * tests/other-tests/gmp.m4: Changed to use mpeval().
6528 * src/evalmp.c: New file for compiling eval.c as gmp aware.
6529 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
6531 * src/eval.c: Now includes "numb.c" directly. Everything in this
6532 file must by static, except evaluate(), which is changed to
6533 mp_evaluate() if USE_GMP in force.
6535 * src/numb.c: Changed to be included by eval.c instead of being
6536 compiled separately. Everything is declared static.
6538 * src/numb.h: Removed declarations of functions, as numb.c is now
6541 * src/builtin.c: Declaration of m4_mpeval() added.
6542 Inserted `mpeval' in builtin table.
6543 (do_eval): New function with common code for m4_eval and m4_mpeval.
6544 (m4_mpeval): New function for gmp version of eval.
6546 * src/m4.h: Declaration of mp_evaluate().

6549 (EXTRA_m4_SOURCES): Now has numb.c and numb.h
6551 * src/m4.c (main): m4 --version also shows which options were used
6552 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
6554 1998-11-27 René Seindal <rene@seindal.dk>
6556 * Error messages now always print program name before input file
6557 name as specified by GNU coding standards. Reported by Akim
6558 Demaille <demaille@inf.enst.fr>.
6560 * doc/m4.texinfo (Include): Change due to changed error message
6564 * tests/get-them: Minor change to sed script due to changed error
6567 * src/m4.c (print_program_name): New func used to print program
6568 name, input file and line number in error (). Used as an
6569 error_print_progname handler.
6570 (reference_error): Removed.
6571 (main): Assigns error_print_progname.
6573 * src/m4.h (M4ERROR): Removed reference_error ().
6575 1998-11-25 René Seindal <rene@seindal.dk>
6577 * Updated to libtool 1.2b.
6579 * src/builtin.c (install_builtin_table): Added braces to avoid
6580 warning of ambiguous 'else'.
6582 * src/module.c: Inserted search path code from path.c modified to
6584 (module_init): Configured default path used only if M4MODPATH is
6586 (module_try_load): Now reads libMODULE.la as generated by libtool
6587 for actual module name.
6588 (module_load): Gives better error messages on failure.
6590 * src/m4.h: Added declarations of structures and functions for
6591 generic search path handling.

6594 functions of more generic search path handling.
6596 1998-11-24 René Seindal <rene@seindal.dk>
6598 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
6599 included gettext, as <libintl.h> might not be found
6600 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
6602 1998-11-22 René Seindal <rene@seindal.dk>
6604 * src/output.c (insert_diversion): Fixed bug that might cause m4
6605 to read from standard output! Triggered by input
6606 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
6607 so now 'undivert(0)' does nothing.
6609 1998-11-18 René Seindal <rene@seindal.dk>
6613 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
6614 could be changed when compiling a illegal regexp, causing later
6615 use of the regexp to dump core.
6617 * src/module.c (module_load): Changed error message to conform to
6620 * src/m4.c (usage): Added message about reporting bugs.
6622 * doc/m4.texinfo (Changeword): Corrected a wrong example.
6623 (Changeword): Added note about the type of regexps used.
6625 * ltconfig, ltmain.sh: New files from Libtool 1.2.

6630 * acm4/modules.m4 (AM_WITH_MODULES): Redone completely to work
6633 * modules/Makefile.am: Changed completely to compile modules using
6634 libtool. The modules are compiled as shared libraries, and are
6635 renamed when installed.
6637 * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
6638 USE_SHL_LOAD to HAVE_SHL_LOAD
6640 * src/builtin.c (shipout_string): Now tests for a NULL string.

6643 functions to load shared objects. Intended to encapsulate the non
6644 portable parts better and to reduce the number of #ifdefs in the
6647 * Makefile.am (DIST_SUBDIRS): Instead of EXTRA_DIST for added
6648 directory modules/ to the distribution.
6650 1998-11-15 René Seindal <rene@seindal.dk>

6655 functions: getcwd, getlogin, getpid, getppid, getuid, getpwnam,
6656 getpwuid, hostname, rand, srand, getenv, setenv, unsetenv, uname.
6658 * src/builtin.c (shipout_string): New convenience function for
6659 builtins and modules.
6661 * src/module.c (module_load): Tentative support for
6662 shl_load/shl_findsym, but I cannot test it. Copied from MetaHTML.
6664 * Makefile.am (SUBDIRS): Directory modules added if configured.
6666 * modules/Makefile.am: Now correctly compiles and installs
6667 modules in pkglibexecdir.

6670 These two are now initialised by autoconf macros.
6672 * src/path.c (module_env_init): MODULE_PATH is always on the
6675 * src/Makefile.am: Now generated pathconf.h which defined the
6676 default MODULE_PATH.
6678 * configure.in (pkglibexecdir): Added defintion of pkglibexecdir,
6679 where modules are installed.
6681 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
6682 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
6683 build and install automatically, and it is prepared for other
6684 interfacec than dlopen().
6686 * src/builtin.c (predefined_tab): Added __m4_version__ for the
6687 current version of GNU m4. It is a GNU extension.

6719 * tests/Makefile.am (GENERATED_TESTS): Renamed gentest to
6722 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): Added manually
6723 maintained tests in tests/other-tests. These currently tests for
6724 8-bit transparency, multiple precision arithmetic and sync-line
6725 output. Test for stackoverflow detection does not work.
6727 * examples/Makefile.am (TESTS): Added tests for all example files.
6729 * examples/mktests.sh: New file. Help program for creating test
6732 * tests/mkconfig.sh: New file to generate tests/config.m4 and

6765 * src/builtin.c (builtin_tab): Builtin format marked as blind.
6767 1998-10-07 René Seindal <rene@seindal.dk>
6771 * tests/Makefile.am (GENERATED_TESTS): Changed .m4 extension to
6772 .test, as the files are no longer just m4 input.
6774 * tests/get-them (FILE): Changed .m4 extension to .test.
6776 * src/m4.h (token_type): New token type TOKEN_SPACE introduced.
6777 Otherwise quoted strings with leading whitespace first in a macro

6780 * src/macro.c (expand_token): Handles new token type TOKEN_SPACE.
6781 (expand_argument): Do.
6783 * src/input.c (next_token): SPACE and NUM/OTHER characters are only

6785 character. Otherwise they might include a comment/quote leader.
6786 (next_token): Returns new token type TOKEN_SPACE.
6788 * src/builtin.c (push_builtin_table): New function to push a
6789 builtin_table on the stack without installing its contents.
6790 (find_builtin_by_name): Added call to push_builtin_table() if
6791 reading frozen files. Otherwise the builtins named in the frozen
6792 files could not be found.

6818 that are of use for other modules (shipout_int, numeric_arg,
6819 skip_space, bad_argc), and the macros ARG() and DECLARE().
6821 * src/builtin.c (install_builtin_table): New function. Each
6822 module brings in a builtin_table, which is pushed on a stack.
6823 (struct builtin_table): New struct for list of builtin_tables.
6824 (m4_loadmodule): New function to implement builtin "loadmodule".
6825 (shipout_int): No longer static, to be used by modules.

6846 * configure.in: Added modules/Makefile to AC_OUTPUT.
6848 * configure.in: Added code to implement --with-modules. Tests for
6851 * acconfig.h: Added WITH_MODULES
6853 1998-10-02 René Seindal <rene@seindal.dk>
6855 * examples/Makefile.am (pkgdata_DATA): Removed special target for
6856 check and variables TESTS. These tests are now run from the
6859 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
6860 directory. The files stay there but the tests are run from the
6863 * tests/Makefile.am (EXTRA_DIST): Added run-test.
6865 * tests/run-test: New file. Run a test manually
6867 * tests/Makefile.am, tests/get_them: Moved automatically generated
6868 tests (from the manual) to sub directory tests/gentest/. The
6869 tests/ directory had gotten a bit messy.
6871 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
6873 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\
6874 wrap}.test: Added a few testcases.
6876 1998-08-21 Erick Branderhorst <Erick.Branderhorst@asml.nl>

6886 $(top_srcdir)/acinclude.m4 to be used by aclocal.
6888 * tests/defs (LANGUAGE, LC_ALL, LANG): force them to be
6889 `C'. Reported by Ulrich Drepper.
6891 * Makefile.am (SUBDIRS): Removed checks directory
6892 * configure.in (AC_OUTPUT): Removed checks/Makefile
6894 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
6895 the space when m4.texinfo is edited and whitespace.el is active.
6896 (Defn,example): idem.
6898 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
6900 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
6901 ../COPYING. ../Makefile is a file which is certainly present when
6902 test is executed in testSubDir. One can't be sure that the COPYING
6903 file is in .. or ../.. in all situations, the ../Makefile is
6906 * doc/m4.texinfo (Include): adjusted expected test output
6907 according to new tests, i.e. the input will always come from the
6908 file `in' created by the test.
6910 * tests/Makefile.am: Added three lines at the top to get
6911 esyscmd.1.test working.
6913 * tests/get-them: modified to generate clearer tests who will need
6914 less maintenance when new test examples are created in
6915 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
6916 need the generic file `defs') shell scripts creating `in', `ok',
6917 `out' and when apropriate `okerr' and `err' in the directory
6918 `testSubDir' when executed. The compare of `ok' and `out'
6919 (and of `okerr' and `err') will be the exit status of the test.
6920 `out' must match `ok' (and `okerr' must match `err') for the test
6923 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
6924 the tests generated by tests/get-them getting it input normally
6925 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
6926 (dot) before the numeric part) is reserved for all other (hand
6927 written) tests. The `+' means one or more times.
6929 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
6931 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
6932 supported short man page to refer to info documentation
6933 * helptoman.pl: added
6934 * configure.in: AC_PATH_PROG(PERL,perl)
6935 * Makefile.am (SUBDIRS): doc after src
6937 * libitized with libit 0.5 from
6938 ftp://ftp.iro.umontreal.ca/pub/contrib/pinard/maintenance/libit.

6945 * configure.in (AC_CHECK_FUNC): getopt_long
6947 * src/m4.c (usage): Report bugs to m4-bugs@gnu.org.

6958 * src/builtin.c (m4_changesyntax): Added builtin macro
6959 "changesyntax" to modify the syntax table.
6961 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax
6962 table. All categories are assigned a syntax code and tokens are
6963 read according to this table.
6965 1998-08-09 René Seindal <rene@seindal.dk>
6967 * src/numb.{c,h}: New files, implements multiple precision eval
6968 using GNU gmp. Originally submitted by John Gerard Makecki
6969 (johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.
6971 * doc/m4.texinfo (Eval): Added documentation for multiple
6972 precision arithmetic library support.
6974 * src/m4.{c,h}, src/eval.c, src/builtin.c, configure.in: Changes
6975 to accommodate multiple precision eval.
6977 1998-08-07 René Seindal <rene@seindal.dk>
6979 * src/input.c (MATCH, match_input), src/m4.h: changed definition
6980 of comment and quote strings to `unsigned int' to allow eight bit
6981 chars (reported by andrewb@zip.com.au (Andrew Bettison)).
6983 * src/builtin.c, doc/m4.texinfo: Builtin `syncoutput' added by
6984 patch from Mike Howard <mike@clove.com>
6986 1998-08-06 René Seindal <rene@seindal.dk>
6988 * gettext.m4: corrected AM_WITH_NLS to handle use of installed
6991 1998-08-03 René Seindal <rene@seindal.dk>
6995 * src/m4.h: Added ifdef ENABLE_NLS around include of <libintl.h>
6996 and _ macro. M4 now builds with --disable-nls.
6998 * src/m4.c (main): reintroduced textdomain(PACKAGE) to get gettext
6999 to look for right message catalogs. Call indef'ed by ENABLE_NLS.
7001 * configure.in (ALL_LINGUAS): Added complete list of translations:
7002 de fr it ja nl ru sv.
7004 1998-05-23 Erick Branderhorst <Erick.Branderhorst@asml.nl>
7006 * po/nl.po: Dutch translation by Erick Branderhorst.
7008 * po/fr.po: French translation by Erick Branderhorst, based on the
7009 translations by François Pinard in fr.msg and m4.cod.
7011 1998-05-22 Erick Branderhorst <Erick.Branderhorst@asml.nl>
7015 * src/m4.c: #include <signal.h> not <sys/signal.h>.
7017 * src/Makefile.am: CFLAGS = -Wall @CFLAGS@.
7019 * checks/Makefile.am: explicit list tests in CHECKS.
7021 * configure.in, {,src,doc,lib,examples,checks}/Makefile.am,

7023 mkinstalldirs, install-sh: Added automake (1.3) support.
7025 * lib/{alloca.c,error.{c,h},get{date.h,opt.{c,h},opt1.c},
7026 obstack.{c,h},regex.{c,h},strtol.c,xmalloc.c,xstrdup.c}:
7027 Used libitize (0.4) to update.
7029 * configure.in, ABOUT-NLS, intl/*, po/*: Added gettextize
7030 (0.10.25) support. Removed LOCALE, fr.msg, m4.cod and adjusted
7033 * src/stackovf.c: #ifdef USE_STACKOVF ... #endif to (de-)activate

7058 * src/m4.c, src/builtin.c, src/debug.c, src/eval.c, src/freeze.c,
7059 src/input.c, src/macro.c, src/output.c, src/path.c,
7060 src/stackovf.c, src/symtab.c: Use _ macro over all localizable
7063 1994-11-07 François Pinard <pinard@iro.umontreal.ca>
7065 * doc/Makefile.in (stamp-vti): Use new -r option to date.

7081 be opened, return immediately after producing the error message.
7082 Reported by Andreas Schwab.
7084 * configure.in: Check for const only after having found possible
7085 ANSIfying compiler flags, this is of no use to check it before.
7086 Reported by Alexander Lehmann.
7088 1994-11-01 François Pinard <pinard@iro.umontreal.ca>
7090 * src/macro.c (collect_arguments): Cast obstack arguments to
7091 (voidstar), so avoiding compiler warnings.
7092 Reported by Joseph E. Sacco.
7094 * src/freeze.c (produce_frozen_state): Cast printed lengths to
7095 (int) so they correspond to %d format items.
7096 Reported by Joseph E. Sacco.
7098 * src/m4.c (main): Cast the argument to xfree to (voidstar).
7099 * src/symtab.c (free_symbol): Idem.

7113 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
7114 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
7115 defines __STDC__ to 0, for indicating it is *not* ANSI!
7116 Reported by Kaveh R. Ghazi.
7118 * configure.in: Added obsolescent tests for AIX and Minix.
7120 * doc/Makefile.in (mostlyclean): Remove texclean in dependencies,

7133 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
7134 Remove the sed filter after ansi2knr for debug.c. Use $O instead
7135 of $U, put underline in extensions rather than in basenames. Use
7136 implicit rules, now that regularity makes this possible.
7137 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
7138 of ansi2knr whenever it is needed.
7139 * configure.in: Adjusted for correct STACKOVF substitution.
7140 * src/debug.c (trace_format): When not __STDC__, use (...) as a
7141 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.

7159 * {,/*}Makefile.in: Use && after all cd, in case they fail.
7161 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

7185 * configure.in: Do not add -O to CFLAGS for GNU C, now that
7186 configure does it automatically.
7187 Reported by Jim Meyering.
7189 1994-09-23 François Pinard <pinard@iro.umontreal.ca>
7191 * src/stackovf.c: Declare the handler_t typedef earlier in the

7221 * Makefile.in: Make TAGS in lib also, not just in src.
7222 Reported by Karl Berry.
7224 * Makefile.in (distclean, realclean): Instead of recursively
7225 calling $(MAKE) for the -local part, allow parallel execution of
7226 -recursive and -local, only delay the removal of config.status,
7227 which is repeated in both goals.
7229 1994-09-13 François Pinard <pinard@iro.umontreal.ca>
7233 * Makefile.in: Group all *clean-recursive goals in one, using sed
7234 to remove `-recursive' while calling make recursively. Also, use
7235 a subshell for each recursive $(MAKE).
7236 Reported by Jim Meyering.
7238 * src/m4.h (memcpy): Define with bcopy for BSD systems.
7239 Reported by Kaveh R. Ghazi.
7241 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS

7297 Reported by Jim Meyering.
7299 Solidify frozen files with respect to -P:
7300 * src/m4.c: Have -P set prefix_all_buitins variable instead of
7301 calling a function by that name. Declare the variable.
7302 * src/m4.h: Adjust declaration for prefix_all_buitins.
7303 * src/builtin.c (builtin_init): Merge in functionality from
7304 previous prefix_all_buitins function, while making entries in the
7305 symbol table, but not modifying the builtin description itself.
7307 * src/freeze.c (reload_frozen_state): Add a useless `break;',
7308 because *many* compilers do not accept an empty `default:'.
7309 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
7310 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
7312 * configure.in: Use AC_TYPE_SIGNAL.

7322 functions, for implementing a global MAXIMUM_TOTAL_SIZE instead of
7323 a per buffer MAXIMUM_BUFFER_SIZE.
7325 * src/output.c (output_text): New function, for optimizing the
7326 output of strings of characters. Use it.
7328 1994-08-30 François Pinard <pinard@iro.umontreal.ca>
7330 * doc, src: New directories reorganizing the distribution.
7331 * doc/Makefile.in, src/Makefile.in, examples/Makefile.in: New
7333 * Makefile.in: Adjusted.
7334 * configure.in: Configure new Makefiles.
7336 * m4.h: Declare STRING typedef. Use it for comment and quote
7337 strings, adjusting all references. (This is the rudiments of a
7338 beginning for the eventual withdrawal of NUL terminated strings.)
7339 * output.c (shipout_text): Accept a length parameter, and use it.
7340 All callers adjusted.
7342 1994-08-29 François Pinard <pinard@iro.umontreal.ca>
7344 * m4.h: Include <unistd.h> if it exists.

7361 Reported by David MacKenzie.
7364 * output.c (freeze_diversions): New function.
7365 * m4.h: Declare freeze_diversions.
7366 * freeze.c: Document frozen file format, revise it, call
7367 freeze_diversions to add diversions to frozen format, and code to
7368 reload them properly.
7369 * m4.c: Do not undivert automatically at end when status being
7370 frozen. Do not call builtin_init when reloading frozen state.
7372 Speed up diversion processing:
7373 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
7374 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
7375 structure and variables, cached variables out of output_diversion,
7376 reallocate_diversion_for and OUTPUT_CHARACTER.
7377 (shipout_text, make_diversion, insert_diversion): Adapted to new
7379 (insert_file): Use better buffering.

7385 dist works from another build directory.
7387 1994-08-27 François Pinard <pinard@iro.umontreal.ca>
7389 * symtab.c (hack_all_symbols): Use hash_table_size instead of

7392 * builtin.c (DECLARE): Simplify by using _ ().
7394 * freeze.c: New file.
7395 * Makefile.in: Compile it, distribute it.
7396 * m4.c: Recognize, document and process --freeze-state (-F) and
7397 --reload-state (-R) options. Pass a true flag to builtin_init
7398 only if no reloading some state.
7399 * builtin.c (define_builtin): Remove static specifier.
7400 (find_builtin_by_name): Remove static specifier.

7416 Reported by Akiko Matsushita.
7418 1994-08-12 François Pinard <pinard@iro.umontreal.ca>
7420 * m4.h: Include <sys/types.h>.
7421 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
7422 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
7424 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
7426 * builtin.c (dump_args): Declare len as size_t, not int.
7428 * debug.c: Prototype the forward declaration of debug_set_file.
7430 * builtin.c (m4_undivert): Replace div by file, for avoiding the
7431 shadowing of this variable.
7432 * output.c (insert_diversion): Idem.
7434 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
7435 (input_init): Duplicate default quote and comment strings.

7442 * Makefile.in (distclean-local): Also delete config.cache.
7444 * m4.c (usage): Reorganize the --help output by topic. Include a
7445 description for debugging flags.
7447 1994-07-29 François Pinard <pinard@iro.umontreal.ca>
7449 * configure.in: If sigaction is available and SA_ONSTACK defined,
7450 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
7451 defined, use sigvec. Else don't compile stackovf.c.
7452 * stackovf.c (setup_stackovf_trap): Idem.
7453 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
7456 1994-07-21 François Pinard <pinard@iro.umontreal.ca>

7460 1994-07-18 François Pinard <pinard@iro.umontreal.ca>
7464 1994-07-17 François Pinard <pinard@iro.umontreal.ca>
7466 * configure.in: Check for sigaction and sigvec. Add a new delayed
7467 check for RLIMIT_STACK, combine in the checking for getrlimit.
7468 All those things are not universally available.
7469 * stackovf.c: Split setting up the trap handler and catching
7470 signals, for better taking care of various configure outcomes.
7471 * examples/stackovf.sh: Correct a typo.
7472 Reported by Eric Backus, Jim Avera and Jim Meyering.
7474 1994-07-16 François Pinard <pinard@iro.umontreal.ca>
7476 * ansi2knr.c: New version sent by its author, Peter Deutsch.
7478 1994-07-15 François Pinard <pinard@iro.umontreal.ca>
7480 * Makefile.in: Modify so parallel make will not try making
7481 lib/libm4.a twice simultaneously.
7482 Reported by Jim Meyering.
7484 1994-07-14 François Pinard <pinard@iro.umontreal.ca>
7486 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
7487 error message, for when no code possibility exists. Even if this
7488 line is completely #ifdef'ed out, it brings a syntax error.
7489 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
7491 * Makefile.in (install): Have install depend on all too, for lib
7492 to be remade as needed.
7494 * examples/stackovf.sh: Try ksh, bsh and bash for shells
7495 providing ulimit, instead of using only ksh.
7496 Reported by Jim Avera and Joseph E. Sacco.
7498 1994-07-12 François Pinard <pinard@iro.umontreal.ca>
7500 * Makefile.in (check): Have it depend on all instead of m4. In
7501 this way, a change in lib will be detected and processed.
7503 * builtin.c (numeric_arg): Use strtol and verify the conversion,
7504 instead of using sscanf which stops as soon as there is a
7505 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
7506 and divert(1xyzzy) were all accepted without any warning or error
7508 * m4.h: Declare strtol as long if not including stdlib.h.
7509 * configure.in: Check for limits.h, and replace strtol if missing.
7510 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
7511 * lib/strtol.c: New file, from elsewhere.
7512 Reported by Andreas Schwab.
7514 1994-07-07 François Pinard <pinard@iro.umontreal.ca>
7516 * macro.c (expand_macro): Cast value to (boolean) prior to
7517 assigning it to traced.
7518 Reported by Tom McConnell.
7520 * Makefile.in (m4): Always make all in lib first.
7521 Reported by Jim Meyering.
7523 1994-07-06 Jim Avera <jima@netcom.com>
7525 * stackovf.c: Isolated OS-dependent sections; Improved portability,
7526 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
7527 handlers), and a default error message if the fault address is not
7528 available (when neither siginfo.h nor BSD sigcontext are supported).
7529 * configure.in: Changes for stackovf.h: Check for sigcontext,
7530 sigaction, sigstack, and define rlim_t as int if necessary.
7531 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
7532 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
7533 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
7535 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
7537 * configure.in: Use AC_SET_MAKE.
7538 * Makefile.in: Use @SET_MAKE@.

7542 Reported by Ian Taylor.
7544 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
7546 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
7547 because siginfo.h is unrelated to standard headers, and siginfo.h
7548 is already checked for.
7549 Reported by Joseph E. Sacco.
7551 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
7553 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
7556 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
7558 * builtin.c (substitute): Use \& to represent this part of the
7559 string which was matched by the whole regexp, instead of
7560 representing the whole string. Any usage of \0 issues a warning
7561 and acts like \&, it will disappear in some subsequent release.
7563 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
7565 * m4.c: Complete prototype for forwarded declaration of usage.
7567 * input.c (init_macro_token): Correct own reference in error
7568 message. Previous name get_macro_func was referred to instead.
7569 (next_char): Correct own reference in error message. Previous
7570 name advance_input was referred to instead.
7572 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
7573 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
7574 and_term, not_term, logical_not_term, cmp_term, shift_term,
7575 add_term, mult_term, exp_term, unary_term, simple_term): Add
7576 prototype to forwarded declarations. Declare parameter v1 as
7577 eval_t * instead of int *. Same for local variable v2 in dyadic
7578 functions. Same for result in exp_term.
7579 * builtin.c (m4_eval): Declare value as eval_t instead of int.
7580 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
7581 unsigned_eval_t instead of unsigned int. Change casts accordingly.
7582 (shipout_int): Cast first argument of ntoa to eval_t.
7583 Reported by Thorsten Ohl.
7585 * macro.c: Complete the prototypes of forwarded expand_macro and
7587 Reported by Thorsten Ohl.
7589 * m4.h: Define voidstar as void * or char * depending on __STDC__.
7590 The Ultrix 3.1 compiler cannot do much with void pointers.
7592 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
7593 * m4.c (xfree): Replace void * by voidstar.
7594 Reported by Tom McConnell.
7596 * ansi2knr.1: New, from elsewhere.
7597 * Makefile.in (DISTFILES): Distribute ansi2knr.1
7599 * Makefile.in (stamp-h.in): Avoid running ./config.status if
7600 stamp-h does not exist yet. This avoids running it a second time
7601 just after the initial ./configure.
7602 Reported by David MacKenzie and Tom McConnell.
7604 * m4.h: Replace the enum debug_info declaration with a series of
7605 #define's. The Ultrix 3.1 compiler would otherwise need casting
7606 (int) to most references, when used in expressions.
7607 Reported by Tom McConnell.
7609 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
7611 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
7612 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
7613 calls the compiler. Previously, FP_PROTOTYPES was only calling
7614 the preprocessor; by not being subject to CFLAGS, this was
7615 discouraging those flags asking for ANSI compilation.
7616 * acconfig.h: Document HAVE_PROTOTYPES.
7617 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
7618 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
7619 Reported by Eric Backus.
7621 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
7622 from the environment. Default CFLAGS to -g if not set.
7623 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
7624 * lib/Makefile.in: Have CFLAGS substituted from configure.
7625 Reported by Eric Backus and Tom McConnell.
7627 * configure.in: m4_undefine changeword before using AC_ENABLE.
7629 * m4.h: Declare prototypes for error (for ANSI compilers only),
7630 prefix_all_builtins and reference_error.
7631 Reported by Tom McConnell.
7633 * input.c (set_word_regexp): Do not try to initialize the array
7634 test from a string, this does not work with non-ANSI compilers.
7635 Reported by Eric Backus.
7637 * Makefile.in (dist): Clean examples/ before saving it.
7638 (distclean-local): Also remove stamp-h.
7639 Reported by Eric Backus.
7641 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
7643 Reported by Tom McConnell.
7645 * checks/Makefile.in (clean): Depends on mostlyclean.
7646 (mostlyclean): New goal.
7648 1994-06-24 François Pinard <pinard@iro.umontreal.ca>
7650 * Makefile.in (DISTFILES): Distribute install.sh.
7651 * install.sh: New file, copied from elsewhere.
7652 Reported by Assar Westerlund and Kaveh R. Ghazi.
7654 1994-06-23 François Pinard <pinard@iro.umontreal.ca>
7656 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
7657 * acconfig.h: Explain ENABLE_CHANGEWORD.
7659 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
7660 from code provided by Pete Chown]
7661 * m4.h: Add original_text field to u_t variant of union u.
7662 Declare TOKEN_DATA_FUNC macro.
7663 * builtin.c: Declare changeword.
7664 (m4_changeword): New function.
7665 * input.c: Include "regex.h", define variables with word regexps.
7666 (input_init): Initialize the word regexp.
7667 (set_word_regexp): New.
7668 (next_token): Declare local variables, use the previous code if
7669 default_word_regexp is true. Else, match using a new code. Save
7671 * macro.c (expand_token): Ship out original text if not a macro
7673 Reported by Krste Asanovic and Pete Chown.
7675 [These modifs all depend upon ENABLE_CHANGEWORD]
7676 * m4.h: Declare external user_word_regexp.
7677 * m4.c: Declare user_word_regexp, and initialize it from
7678 --word-regexp or -W, or NULL if not specified.
7679 * input.c: Use user_word_regexp if specified, instead of
7680 DEFAULT_WORD_REGEXP.

7690 Implement -LNUMBER or --nesting-limit=NUMBER to change its
7692 * m4.h: Declare nesting_limit as external.
7693 * macro.c (expand_macro): Stop execution whenever nesting limit
7695 Reported by Bengt Mertensson.
7697 * eval.c (evaluate): Diagnose excess characters in eval input.
7698 Things like `eval(08)' used to return 0 with no diagnostic.
7700 * m4.h: Capitalize first letter of all macro arguments in
7703 * m4.c: Declare warning_status, initialize it to 0. Add new
7704 option -E, or --fatal-warnings, which sets warning_status to
7705 EXIT_FAILURE instead.
7706 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
7707 EXIT_FAILURE if not otherwise done by header files.
7708 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
7709 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
7710 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first

7722 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
7723 also tested it on a Sun Sparc workstation running SunOS 4.x.
7725 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
7726 49.format check, abusing a `union values' argument with sprintf
7727 without selecting the proper field. Now, save the formatting type
7728 first, delaying the fetch of the corresponding argument.
7729 Reported by Joseph E. Sacco and Tom Quinn.
7731 * format.c (format): Remove const from char *fmt declaration when
7732 not HAVE_EFGCVT, because a NUL may be forced into it.
7734 * m4.h: Declare atof() when not STDC_HEADERS.
7735 Reported by Joseph E. Sacco.
7737 * Regenerate configure using Autoconf 1.11, this corrects a

7755 substitute ${U}stackovf.o for STACKOVF.
7756 * acconfig.h: Declare USE_STACKOVF.
7757 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
7758 * m4.h: Declare setup_stackovf_trap().
7759 * m4.c: Call setup_stackovf_trap().
7760 * tests/stackovf_test.sh: New file.

7774 of `if ... else /* nothing */' for if macros.
7775 Reported by Jim Meyering.
7777 * builtin.c (m4_regexp): Reorganize the code for avoiding a
7778 warning from gcc about `repl' possibly used before defined.
7779 Reported by Jim Meyering.
7781 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
7782 Reported by Jim Meyering.
7784 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
7786 * m4.h: Move the conditional definition of volatile after the
7787 inclusion of system files, because they may define it first.
7789 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
7791 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
7792 get around a problem with Alpha make seeing a syntax error, there.
7793 Reported by Vern Paxson.
7795 1994-01-03 François Pinard <pinard@iro.umontreal.ca>
7797 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.

7811 Use them in exit() and usage() calls.
7813 1993-11-27 François Pinard <pinard@iro.umontreal.ca>
7815 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
7816 syserr() macro. Delete errref, add reference_error and M4ERROR.
7817 * m4.c: Replace errref, which was returning an input reference
7818 string, with reference_error, which prints it on standard error.
7819 * builtin.c, output.c: Use errno as second parameter to error,
7820 instead of using syserr() with %s.
7821 * *.c: Use M4ERROR instead of error: no more errref() with %s.
7822 Doing so, the program name appears after the input reference
7823 instead of before, which eases M-x next-error processing.
7825 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
7827 * checks/get-them: Escape braces with backslashes in patterns,
7828 because HPUX-9.01 awk needs this.

7839 * *.c: Use error() systematically in place of all error macros,
7840 now that error() flushes stdout first. Make needed adjustments.
7842 * m4.h: Remove const in sys_errlist[] declaration, it creates
7843 conflicts on SGI and Alpha.
7844 Reported by Kaveh R. Ghazi.
7846 1993-11-20 François Pinard <pinard@iro.umontreal.ca>

7864 * input.c (input_init): Initialize quote and comment strings
7865 explicitely instead of calling set_quotes and set_comment: by
7866 doing so, we ensure we do not free uninitialized variables.

7869 expected is on the left and the obtained on the right.
7871 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
7872 macros. Delete declarations for m4error, warning, fatal and
7873 internal_error, add declaration for error_message_prefix.
7874 * m4.c: Delete m4error, warning, fatal and internal_error
7875 routines, add error_message_prefix routine.
7876 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
7877 warning with WARNING*, fatal with FATAL* and internal_error with
7879 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
7880 this is not needed anymore.
7882 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
7883 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
7884 and debug_message, add declaration for debug_message_prefix.

7887 debug_message_prefix routine.
7888 * builtin.c, debug.c: Replace debug_print routine calls with

7895 (trace_format): Use stdarg instead of varargs if __STDC__.
7897 * configure.in: Remove checks for vfprintf and _doprnt. These

8205 * version.h: Deleted.
8206 * Makefile.in: Remove references to version.h.
8208 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
8209 production, by using a simpler and more robust algorithm. This
8210 solves the problem of synclines sometimes written in the middle of
8211 an output line. Delete sync_line() and output_lines variable.
8212 * m4.h: Remove sync_line prototype and output_lines declaration.
8213 * input.c (next_char), output.c (shipout_text): Remove references
8215 * input.c (push_file, pop_file): Merely put the value -1 in
8216 output_current_line instead of calling sync_line, for delaying a
8217 single `#line NUM FILE' before next output line. Do not test
8218 for sync_output, because this is unnecessary clutter.
8219 * output.c (make_divertion, insert_divertion): Idem.
8220 * input.c: Rename must_advance_line to start_of_input_line, for
8223 * debug.c (trace_header): Select a new debug line format, which
8224 better complies with GNU standards for formatting error messages.
8225 With option `-dfl', M-x next-error might be used on the output.
8226 * m4.c (vmesg): Adjust format of error output to GNU standards.
8227 * m4.texinfo: Adjust examples for `make check' to work.
8229 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
8230 case for enum debug_info constants, which were all lower case.
8232 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
8234 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
8235 collected patches. I tried a few times using newer regex.[ch], it
8236 mysteriously stopped aborting with this one. Insecure feeling...
8237 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
8239 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
8241 * m4.c: Change `--no-warnings' to `--silent'.
8242 Reported by David MacKenzie.
8244 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
8245 leave it off for now. See comment in m4.c for justification.
8246 Reported by David MacKenzie.
8248 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
8249 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
8251 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
8253 * Makefile.in: Ensure recursive cleaning is done before local
8254 cleaning for all clean goals.
8256 * builtin.c (ntoa): Ensure the value is always interpreted as a
8257 signed quantity, whatever the radix is.
8259 1992-11-18 Jim Meyering <meyering@idefix>
8261 * builtin.c, format.c, input.c: Split long lines.
8262 * m4.c: Use typedef macro_definition instead of struct
8264 * symtab.c: Use typedef symbol instead of struct symbol.
8266 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
8268 * *.[ch]: Remove all trailing whitespace, in code and comments.
8270 * configure.in: Find some awk.
8271 * Makefile.in: Add $(AWK) to MDEFINES.
8272 * checks/Makefile.in: Transmit $(AWK) to get_them.
8273 * checks/get_them: Use $AWK instead of gawk. Add a close in the
8274 awk script when switching files, because without this, mawk runs
8275 out of file descriptors.
8277 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
8279 * Makefile.in (realclean): Delete m4.info*.
8280 Reported by Jim Meyering.
8282 * Makefile.in: Adjust and link with checks/Makefile.
8283 * checks/Makefile.in: New.
8284 * configure.in: Output checks/Makefile.
8286 * checks/get_them: Have the dnl header of each test more
8287 recognizable by next-error, also use a better message.
8289 1992-11-16 Jim Meyering <meyering@idefix>
8291 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
8292 And use that only if __GNUC__ since we're using it's GCC-specific
8293 semantics that tell the compiler the associated function doesn't
8296 * builtin.c (substitute): Don't use character as an array index.
8297 (dumpdef_cmp): Make formal arguments `const void *' to avoid
8298 warnings with gcc -W -Wall on systems with qsort prototype.
8299 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
8302 * eval.c (most functions): Add parentheses to assignments used
8303 as truth values go avoid warnings from gcc -Wall.
8305 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
8306 any functions that don't need external scope.
8308 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
8309 (many functions and arrays): Declare `const'.
8311 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
8313 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
8314 removing the declaration from m4.h. Also rename false to FALSE
8317 * lib/Makefile.in (Makefile): New goal.
8319 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
8320 so heavily loaded. It gets more easily overridable, calling make.
8321 Reported by Jim Meyering.
8323 * Makefile.in (dist): Get .fname from the current directory name,
8324 instead of from version.h. I need updating many files manually,
8325 when the version changes, version.h is just one of them.
8327 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
8329 * m4.h: Remove the tag `boolean' on the enum introducing typedef
8330 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
8331 Reported by Tom McConnell.
8333 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
8335 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
8336 39.cleardiv, which were describing missing or spurious newlines.
8337 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
8338 do not depend on machine word size, `/bin/false' implementation,
8339 or `wc' output format. `make check' is more dependable, now.
8341 * checks/check_them: Summarize the failed tests by listing their
8342 name, at end. If none, issue `All checks successful'. Output
8343 `Checking' instead of `Input file:'.
8345 * checks/get_them, checks/check_them: Reindented.
8347 * Makefile.in (dist): chmod a+r before making the tar file.
8349 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
8351 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
8353 * input.c (next_token): Reinitialize token_buttom just after using
8354 it as a watermark with obstack_free. Or else, a future token, big
8355 enough for triggering reallocation of the obstack chunk, could
8356 void the initialized value of token_buttom, later causing panic in
8357 obstack_free. Rename token_buttom to token_bottom everywhere.
8359 * m4.h: Before declaring errno, first include <errno.h> and
8360 ensure that it does not define errno.
8361 Reported by Richard Stallman.
8363 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
8365 * builtin.c: Define and use DECLARE macro for builtins.
8367 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
8368 argument, this is a common idiom for introducing long comments.
8370 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
8371 arguments. The last argument was silently ignored.
8373 * m4.c (cmd_error): Add a missing semicolon before va_end().
8375 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
8377 * Makefile.in: Now handle protoized sources. Define and use U.
8378 Compile and use ansi2knr with old compilers. Update DISTFILES.
8379 Add `aclocal.m4' to `configure' dependencies.
8380 * ansi2knr.c: New, from Ghostscript distribution.
8381 * configure.in: Define U through FP_PROTOTYPES for old compilers.
8382 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
8383 * aclocal.m4: New, provide FP_PROTOTYPES.
8384 * m4.h: Conditionnaly protoized through Args, save for varags.
8385 * builtin.c: Protoized. Then:
8386 Include <sys/types.h> if size_t is not defined, before "regex.h".
8387 (m4_ifelse): Fetch built-in name properly for diagnostic.
8388 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
8389 (m4_regexp): Add const to `msg' declaration.
8390 (m4_patsubst): Add const to `msg' declaration.
8391 * debug.c: Protoized, save for varargs.
8392 * eval.c: Protoized.
8393 * format.c: Protoized.
8394 * input.c: Protoized.
8395 * m4.c: Protoized, save for varargs. Then:
8396 (xfree): Accept void * instead of char *.
8397 (xmalloc): Return void * instead of char *.
8398 (xrealloc): Accept and return void * instead of char *.
8399 * macro.c: Protoized.
8400 * output.c: Protoized.
8401 * path.c: Protoized. Then cast some (char *) over xmalloc's.
8402 * symtab.c: Protoized.
8404 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
8406 * m4.texinfo: Remove directory from diagnostics in 30.include,
8407 51.eval, 56.errprint and 57.m4exit tests.
8409 * m4.h: Remove declarations for int or void system functions, they
8410 cause more conflicting trouble than they make good.
8412 * configure.in: Avoid configuration header file. Add some tests.
8413 * m4.h: Remove #include "config.h".
8414 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
8415 Then, rewritten for better compliance with GNU standards.
8417 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
8419 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
8420 because of a misplaced #endif.
8422 * Many *.[hc] files: Correct intra-line spacing here and there,
8423 according to GNU indent 1.6 advice.
8425 * configure.in: New, using Autoconf 1.2.
8426 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
8427 * Delete old configure.in, configure, etc/configure.in,
8428 etc/configure, lib/configure.in, lib/configure and config/*.
8429 Reported by Jason Merrill.
8431 * symtab.c (hash): Change (char) NULL to '\0'.
8432 Reported by Jason Merrill.
8434 * Delete .vers, etc/newdist.sh, etc/newvers.sh and
8435 etc/nextvers.sh. Release numbers will be edited `by hand'.
8436 * version.h: De-automatize, force value in.
8438 * m4.c: Changes in order to use a newer getopt.h.
8439 Reported by David MacKenzie.
8441 * checks/: New name for examples/.
8442 * checks/get_them: New location for etc/get_examples.
8443 * checks/check_them: New location for etc/check_examples.
8444 * Makefile.in, checks/get_them, checks/check_them: Adjust.
8445 * lib/vfprintf.c: New location for etc/vfprintf.c.
8446 * Delete empty etc/.
8447 * examples/: New name for test/.
8449 1992-03-10 François Pinard <pinard@iro.umontreal.ca>
8451 * Makefile.in (check): Add m4 as dependency.
8453 * m4.c: Accept --no-warnings instead of --no_warnings, and
8454 --no-gnu-extensions instead of --no_gnu_extensions. Make the
8455 usage message more informative.
8456 Reported by David MacKenzie.

8475 Reported by Hal Peterson.
8477 * eval.c (exp_term): Have N^0 return 1.
8478 Reported by Michael Fetterman.
8480 * eval.c, input.c, m4.h: Remove last comma in enums.
8481 Reported by Mike Lijewski.
8483 * Transfer of maintenance duties from René to François.
8485 1991-10-24 René Seindal <seindal@diku.dk>

8497 * Added default options via the M4OPTS environment variable.
8499 * The built-in format can now be configured to use sprintf as
8500 the formatting engine, for systems without [efg]cvt(3).
8502 * GNU library code is moved to the ./lib subdirectory; other
8503 utility files are now in ./etc.

8510 François Pinard and Roland H. Pesch for providing me with reports.
8512 * The builtins incr and decr are now implemented without use of
8515 * The builtin indir is added, to allow for indirect macro calls
8516 (allows use of "illegal" macro names).
8518 * The debugging and tracing facilities has been enhanced
8519 considerably. See the manual for details.
8521 * The -tMACRO option is added, marks MACRO for tracing as soon
8524 * Builtins are traced after renaming iff they were before.
8526 * Named files can now be undiverted.
8528 * The -Nnum option can be used to increase the number of
8529 divertions available.
