3 * bootstrap (func_update_po): Update pofiles directly from the
5 * po/LINGUAS, po/cs.po, po/de.po, po/el.po, po/fr.po, po/it.po,
6 po/ja.po, po/nl.po, po/pl.po, po/ru.po, po/sv.po: No need to store
7 these files under source control anymore.

10 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
12 * ltdl/m4/m4-gnulib.m4: Update FSF contact address. Somehow this
13 file escaped the address updates on 2005-05-01.
15 2005-07-07 Gary V. Vaughan <gary@gnu.org>
17 * bootstrap: Allow user overriding of gnulib-tool location, and
18 correctly determine module source directories whether gnulib-tool
19 is given as a relative or absolute path, or is found by searching

23 2005-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
25 * ltdl/m4/debug.m4 (m4_CHECK_DEBUGGING): Make sure that both $rm
26 and $RM are defined for various versions of
27 AC_LIBTOOL_COMPILER_OPTION.
29 * bootstrap (AUTORECONF): New variable to allow user overriding of
32 2005-07-07 Gary V. Vaughan <gary@gnu.org>
34 * doc/m4.texinfo (History): Add better notes on the ancestory of
35 GNU m4, and other historical interest.
37 2005-05-08 Gary V. Vaughan <gary@gnu.org>
39 * m4/symtab.c (m4_symbol_rename): New function that performs a low
41 * m4/m4module.h (m4_symbol_rename): Declare it as part of the API.
42 * modules/gnu.c (regsub): Factored out of m4_epatsubst_do...
43 (m4_patsubst_do, m4_renamesyms_do): ...wrappers that use
45 (erenamesyms, renamesyms): ...builtins that use these to implement
46 macro renaming by regular expression.
47 * doc/m4.texinfo (Erenamesyms and Renamesyms): Document them.
48 * tests/generate.awk: Allow some forbidden `m4_' prefixed symbols
49 to stop the new generated tests from choking.
51 2005-05-07 Gary V. Vaughan <gary@gnu.org>
53 Since most of the build is handled from a single Makefile.am now,
54 we can teach make about the dependencies between the m4 binary and
55 the preopened modules it is built against:
57 * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
59 * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
60 of the preopened modules have changed.
62 2005-05-07 Gary V. Vaughan <gary@gnu.org>
64 * configure.ac (gl_MODULES): Add mkstemp for machines that don't
65 have a native implementation.
67 2005-05-06 Gary V. Vaughan <gary@gnu.org>
69 * src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are
70 handled already by gnu/exit.h.
72 * configure.ac (gl_MODULES): Add assert to support a
73 --disable-assert configure time option for NDEBUG setting.
75 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.
76 * bootstrap (src_modules): Add version-etc-fsf.
77 * src/main.c (version_etc_copyright): Removed.
79 * ltdl/m4/m4-getopt.m4 (m4_GETOPT): Synch with gnulib/getopt.m4.
81 2005-05-04 Gary V. Vaughan <gary@gnu.org>
83 * src/m4.h (__CYGWIN__, WIN32): Canonicalise Windows and Cygwin
85 * src/freeze.c (produce_frozen_state): Use \n line-endings even
86 on Windows, so that the frozen file reader will work.
87 Reported by Josef T. Burger <bolo@bolo.com>
89 2005-05-04 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
91 Forward port of a patch that allowed m4-1.4.2 to compile on
94 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
96 * src/m4.h: And include them as appropriate.
97 * src/main.c, src/stackovf.h: Don't include signal.h literally;
98 m4.h will include the correct file.
100 2005-05-04 Gary V. Vaughan <gary@gnu.org>
102 * m4/m4private.h: Make errno visible for the sources patched
105 2005-05-04 Paul Eggert <eggert@twinsun.com>
107 * src/main.c (print_program_name_CB): Preserve errno, since
108 M4ERROR relies on this.
109 * modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
110 * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
111 * m4/path.c (m4_path_search): Don't let "free" trash errno when
114 * m4/output.c (m4_insert_file): Don't assume errno has a valid
115 value simply because fread returns zero. This fixes a
116 portability bug reported by Marion Hakanson in
117 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
119 2005-05-04 Santiago Vila <sanvila@debian.org>
121 * tests/stackovf.test: Use tempfile if available.

125 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=92629
126 * m4/output.c (m4_insert_file): Do not mix buffered and
127 unbuffered I/O, as this breaks on the Hurd.
129 2005-05-04 Gary V. Vaughan <gary@gnu.org>
131 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
132 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
133 and libtoolize does a better job of ltdl importing now too, so
134 take advantage of that while updating the tree:
136 * acm4, config: Moved from here...
137 * ltdl/m4, ltdl/config: ...to here.
138 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
139 src/Makefile.am, tests/Makefile.am: Removed...
140 * Makefile.am: ...and migrated to here, with adjustments to
141 compensate for relative path differences.
142 * commit: Adjust relative paths.
143 * configure.ac: Adjust relative paths.
144 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
146 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
147 the meanwhile, CVS HEAD libtool is needed.
148 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
149 stricly new enough, we also need a patch.
150 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
151 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
152 (gl_MODULES): Don't list getopt and version-etc, as they don't
154 * bootstrap: After running gnulib-tool to import the listed
155 modules, fetch getopt and version-etc into src manually.
156 (ltdldir): Change to ltdl.
157 * src/main.c: Adjust for changes in version-etc API.
158 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
159 but works when the getopt module isn't to be included in the lib.
160 * README: Add note about patching autoconf and automake to

166 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
167 empty file rather than to a nonexistent file. This closes a
168 common security hole.
169 * modules/m4.c (m4_maketemp): Implement the above, by using
170 mkstemp rather than mktemp.

207 * acm4/m4-obstack.m4 (INCLUDE_OBSTACK_H): Likewise.
208 * acm4/m4-regex.m4 (INCLUDE_REGEX_H): Likewise.
209 * m4/system_.h: Likewise, in non-configured includes.
211 2004-10-14 Noah Misch <noah@cs.caltech.edu>,
212 Gary V. Vaughan <gary@gnu.org>
214 * m4/m4.c (m4_context_field_table, m4_context_opt_bit_table):
215 Protect definitions from macro expansion under -DNDEBUG by
216 parenthesising the expanded function names.
217 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
218 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
219 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
220 (m4_is_syntax_macro_escaped): Similarly protect function
221 definitions from macro expansion under -DNDEBUG by #undefing the
222 matching macro names before each definition. Also, move all the
223 function definitions to the end of the file so that any
224 invocations in the rest of the file pick up the fast macro
226 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)
227 (m4_set_debug_file, m4_set_trace_messages)
228 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
229 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
230 (m4_set_max_debug_arg_length_opt): New fast macro versions of the
231 option setter functions.
233 2004-09-23 Gary V. Vaughan <gary@gnu.org>
235 * src/main.c: Include gnulib files from the correct directory.
237 * gnulib/*: Don't store any of the gnulib files in arch, as they
238 generate spurious changes.
239 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
240 gnulib macros now share our macro directory.
241 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
242 * bootstrap: Call gnulib-tool to import from the gnulib tree.
243 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
244 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
245 the gettext macros from autopoint that overwrite the gnulib-tool
246 imported versions. Import sources and Makefile.am into the `gnu'
247 directory. Changed all callers.
248 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
249 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
250 for imported modules.
251 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
252 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
253 hardcoding the gnulib macros they wrap.
255 2004-07-15 Gary V. Vaughan <gary@gnu.org>
257 Latest CVS libtool can preload modules in libraries, including
258 its own module loaders! Tweak m4 so that it doesn't try to treat
259 libltdl's module loaders as m4 modules when freezing and on exit:
261 * gnulib/acm4/*.m4: Don't store these files in arch since they
262 generate spurious changes.
263 * bootstrap: Simplify initial libtoolize call, since CVS
264 libtoolize is smarter these days.
265 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
267 * m4/module.h (m4__module_exit): Missing declaration.
268 * m4/m4private.h (m4__module_next): New function declaration.
269 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
270 encapsulation. Changed all callers.
271 (m4__module_interface): New function to verify m4 loadable module
273 (m4__module_init): Register the interface validator.
274 (m4__module_exit): Only close my own modules.
275 * modules/m4.c (unistd.h): Provide missing declaration.
276 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
277 (m4_expand_ranges): More missing declarations.
278 * modules/modtest.c (export_test): Ditto.
279 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
280 * src/main.c (main): Bump copyright year.
281 * tests/modules.at: Fix sed syntax error.
284 2004-06-17 Gary V. Vaughan <gary@gnu.org>
286 Tweaking to enable compilation with latest CVS libtool and
287 libltdl. We can't just dump the library files directly into the
288 m4 directory anymore now that libltdl is built from pieces itself:
290 * bootstrap: Rewritten to use latest libtoolize sanely, and to
291 set up libltdl subdirectory.
292 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
293 gnulib subdirectory's config.
294 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
295 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
297 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
298 configure.ac, so use AC_WITH_LTDL instead.
299 * Makefile.am (SUBDIRS): Add libltdl.
300 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
302 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
303 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
304 (libm4_la_LIBADD): Add LIBLTDL.
305 * m4/ltdl.c, m4/ltdl.h: Removed.
306 * m4/m4module.h: Include canonical ltdl.h.
309 2004-06-14 Gary V. Vaughan <gary@gnu.org>
311 * gnulib/import: Now updates makefile fragments, and configure.ac.
312 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
313 * gnulib/m4/Makefile.am: include it.
314 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
315 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
316 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
317 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
318 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
319 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,
320 gnulib/acm4/lib-ld.m4, gnulib/acm4/lib-prefix.m4,
321 gnulib/acm4/error.m4, gnulib/acm4/po.m4, gnulib/acm4/regex.m4,
322 gnulib/acm4/stdbool.m4, gnulib/acm4/stdint_h.m4,
323 gnulib/acm4/uintmax_t.m4, gnulib/acm4/ulonglong.m4,
324 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
325 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
326 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
328 * gnulib/m4/getopt_int.h: New source file from latest gnulib
330 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
331 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,
332 gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
333 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
334 Updated source files from latest gnulib.
336 2004-02-29 Gary V. Vaughan <gary@gnu.org>
338 * config/mailnotify: New file for mailing commit notifications,
339 imported from cvs-utils.
340 * commit: Updated from cvs-utils and tweaked for m4.
342 2003-12-01 Gary V. Vaughan <gary@gnu.org>
344 * config/mkstamp: Updated from CVS libtool.
345 * configure.ac: Generate a gnu coding standards compliant version
346 number, and use it for the banner.
347 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
348 mhen the TIMESTAMP changes in ChangeLog, but the file modification
349 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
350 contain the previous version number.
351 * src/main.c: Make --version output conform to the GNU standard.
353 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
354 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
355 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
356 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
357 time_la_SOURCES): ...so that these are defaulted correctly, and
358 can be removed from this file.
359 (AM_LDFLAGS): Add -module...
360 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
361 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
362 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
363 the individual settings can be removed.
364 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
365 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
366 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
367 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
368 time_la_LIBADD): ...so that these are picked up as a deplib of
369 libm4 and don't need to be set explicitly.
371 2003-11-18 Gary V. Vaughan <gary@gnu.org>
373 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
374 from the standard build. It is too fragile.
376 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
377 CVS libtool after merging m4 changes across to libtool.
379 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
380 * m4/path.c (search_path_add): Ditto.
382 2003-11-13 Gary V. Vaughan <gary@gnu.org>
384 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
385 libtool tags we don't use in configure. This reduces the size
386 of the script from over 1Mb to under 700Kb.
388 2003-11-13 Gary V. Vaughan <gary@gnu.org>
390 The import script was not written properly, and the last gnulib
391 import was incomplete. Fixed that problem, and reimport our
392 gnulib dependencies, which picks up the address calculation
393 overflow checks described by Paul below. Also tweak the clients
394 of the gnulib xalloc module not to use deprecated macros:
396 * gnulib/import: Recurse through module dependencies rather than
397 naively descending only one level.
398 * configure.ac: Add calls to gnulib's strnlen and extension module
400 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
402 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
403 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
404 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
405 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
407 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
408 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
409 place of `xcalloc (1, S)'.
410 * m4/m4.c (m4_create): Likewise.
411 * m4/m4private.h (m4_symbol_value_create): Likewise.
412 * m4/symtab.c (symtab_fetch): Likewise.
413 * m4/syntax.c (m4_syntax_create): Likewise.
414 * src/freeze.c (reload_frozen_state): Likewise.
415 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
417 * m4/symtab.c (m4_symtab_create): Likewise.
419 2003-11-13 Gary V. Vaughan <gary@gnu.org>
421 * tests/module.at: Comment typo.
423 2003-10-10 Gary V. Vaughan <gary@gnu.org>
425 * tests/modules.at (modules: importing): Apply some lateral
426 thinking, and use AT_CHECK to compare the output of a sed pass
427 over stderr against the canonical strerror string.
429 * tests/modules.at (modules: importing): Edit the generated stderr
430 output to canonicalize strerror output, before a comparison.
432 2003-10-10 Gary V. Vaughan <gary@gnu.org>
434 Tru64UNIX perl is sloppy with namespace pollution. This patch is
435 careful not to trip over the mess:
437 * modules/perl.c: Some builds of perl install headers that contain
438 `#define try __builtin_try'. Be sure to undefine that macro
439 before `m4/hash.h' gets included, which uses the `try' symbol.
440 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
441 `false' before including `stdbool.h'.
442 (DELETE): This symbol is not in m4's namespace, and is in any
443 case only used internally...
444 * m4/m4private.h (DELETE): ...so move it to here.
445 Reported by Martin MOKREJS <mmokrejs@natur.cuni.cz>
447 2003-10-08 Paul Eggert <eggert@twinsun.com>
449 Don't use XMALLOC and XCALLOC. Once we install the
450 corresponding patch into gnulib, this will fix some
451 address-calculation overflow bugs on hosts where calloc (A, B)
452 returns garbage when A*B overflows.
454 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
455 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
456 xmalloc, XCALLOC with xcalloc.
457 * m4/m4.c (m4_create): Likewise.
458 * m4/m4private.h (m4_symbol_value_create): Likewise.
459 * m4/output.c (m4_output_init): Likewise.
460 * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise.
461 * m4/syntax.c (remove_syntax_attribute): Likewise.
462 * src/freeze.c (reload_frozen_state): Likewise.
463 * src/main.c (main): Likewise.
465 2003-10-07 Gary V. Vaughan <gary@gnu.org>
467 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
468 gnulib/acm4 directories for aclocal m4 macros.
469 * gnulib/Makefile.am (EXTRA_DIST): Removed.
470 (MAINTAINERCLEANFILES): Add Makefile.in.
471 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
473 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.

513 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
514 gnulib/acm4/xstrndup.m4: Reimported from CVS gnulib with
515 gnulib/import script.
516 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/error.c,
517 gnulib/m4/error.h, gnulib/m4/exitfail.c, gnulib/m4/free.c,

520 gnulib/m4/version-etc.c, gnulib/m4/version-etc.h,
521 gnulib/m4/xalloc.h, gnulib/m4/xmalloc.c: Updated from CVS
522 gnulib with gnulib/import script.
523 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
524 guards ready for gnulib-tool to autoupdate on import.
525 * config/debug.m4, config/gmp.m4, config/m4-error.m4,
526 config/m4-gettext.m4, config/m4-obstack.m4, config/m4-regex.m4,
527 config/stackovf.m4: Moved from here...
528 * acm4/debug.m4, acm4/gmp.m4, acm4/m4-error.m4,
529 acm4/m4-gettext.m4, acm4/m4-obstack.m4, acm4/m4-regex.m4,
530 acm4/stackovf.m4: ...to here, to separate aclocal macros from
531 configure time helper scripts.
532 * config/error.m4: Removed; superceded by gnulib/acm4/error.m4.
533 * m4/hash.c, m4/m4.c, m4/macro.c, m4/module.c, m4/output.c,
534 m4/path.c, m4/symtab.c, m4/syntax, m4/system_.h, modules/m4.c,
535 src/main.c, src/stackovf.c: s/xfree/free/g to comply with new
537 * src/main.c (version_etc_copyright): Only output the current
539 (version_etc): Call with new variadic API.
541 2003-09-16 Gary V. Vaughan <gary@gnu.org>
543 * gnulib/m4/version-etc.c, gnulib/m4/version-etc.h: Import
544 version-etc module from CVS gnulib.
545 * po/POTFILES.in: Add gnulib/m4/version-etc.c.
546 * src/Makefile.am: Build it.
547 * src/main.c: Use it.
549 * gnulib/m4/exit.h: Import exit module from CVS gnulib.
550 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
551 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
554 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
555 Gary V. Vaughan <gary@gnu.org>
557 * bootstrap: Separate options.
558 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
559 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
561 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
562 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
563 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
564 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
565 $(LTLIBINTL) for gettext support on cygwin.
566 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
567 have $(LTLIBINTL) from the preloaded module la files.
568 * README: Remove the warning about using --disable-nls on Windows
571 2003-09-15 Gary V. Vaughan <gary@gnu.org>
573 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
574 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
577 2003-09-12 Gary V. Vaughan <gary@gnu.org>
579 * doc/STYLE: Document the gnulib header naming conventions, and
581 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
582 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,
583 gnulib/m4/gettext.h, gnulib/m4/obstack.h, gnulib/m4/regex.h
585 * gnulib/m4/Makefile.am: Remove the rules to build these headers.
587 * gnulib/m4/strtol.c, gnulib/config/strtol.m4: Import strtol
588 module from CVS gnulib.
589 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
590 (gl_FUNC_STRTOL): In favour of the module macro.
592 2003-09-12 Gary V. Vaughan <gary@gnu.org>
594 Replace the getopt code with CVS gnulib getopt. The source files
595 detect whether they are in a glibc environment and preprocess away
596 all of the code if there is a system getopt, so we can compile
597 them into the m4 executable unconditionally:
599 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
600 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
601 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
603 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
605 * src/Makefile.am: Adjust.
606 * src/main.c: Always include our shipped getopt.h.
607 * po/POTFILES.in: Use new location of getopt.c.
609 2003-09-12 Gary V. Vaughan <gary@gnu.org>
611 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
612 * config/Makefile.am: Removed. Automake 1.8 distributes the files
613 in this directory automatically.
614 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
616 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
618 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
620 * modules/Makefile.am (pkglibexecdir): Set it here.
621 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
623 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
624 Import regex module from CVS gnulib.
625 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
626 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
627 do extra substitutions for Makefile.
628 * configure.ac: Use it.
629 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
630 from regex_.h if necessary.
631 * m4/system_.h: Include the correct version of regex.h.
632 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
634 * po/POTFILES.in: Use new location of regex.c.
636 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
637 realloc.c: automake distributes these files already.
639 2003-09-12 Gary V. Vaughan <gary@gnu.org>
641 Replace the xstrzdup code by importing the xstrndup module from
642 CVS gnulib, along with its dependencies: strndup and strnlen:
644 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
645 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
647 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
648 gnulib/config/strndup.m4: Ditto wrt strndup.
649 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
651 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
652 However, contrary to gnulib, we install xstrndup.h.
653 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
654 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
655 is an artifact of the old m4 portability layer.
656 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
657 * m4/system_.h: Include xstrndup.h.
658 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
660 2003-09-11 Gary V. Vaughan <gary@gnu.org>
662 Reimport the latest xalloc module from CVS gnulib, and adjust the
663 m4 sources to take advantage of xalloc xfree. Also create a new
664 macro DELETE with the same semantics as the old m4 XFREE macro,
665 and carefully tweak callers:
667 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
669 * m4/utility.c (xfree): Removed. This function is now supplied by
671 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
672 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
673 * m4/symtab.c (m4_symtab_create): Ditto.
674 * m4/system_.h: Removed XFREE redefine.
675 (DELETE): New macro with same functionality as the original m4
676 XFREE macro, but based on xalloc.h now. Changed all callers.
677 * src/main.c (main): Use XMALLOC macro.
678 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
680 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
682 2003-09-10 Gary V. Vaughan <gary@gnu.org>
684 Import the xalloc module from CVS gnulib, along with its
685 dependencies: exitfail, malloc and realloc. We had different
686 semantics for our XFREE and a function xfree() not supplied by
687 gnulib, so also a bit of work to keep everything running
690 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
691 (gl_XALLOC): Use gnulib equivalents.
692 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
693 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
694 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
695 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
697 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
698 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
699 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
701 (pkgincdir): Removed. Use pkgincludedir instead.
702 * m4/m4private.h (XFREE): xfree already checks for NULL.
703 * m4/system_.h: Use xalloc module, and remove macros already
704 supplied by xalloc.h.
705 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
706 moved the old definition from m4/xmalloc.c to here for now.
708 2003-09-09 Gary V. Vaughan <gary@gnu.org>
710 Import the error and progname modules from CVS gnulib. Our old
711 error.c subsumed the functionality of both, so a little adjustment
712 was required to accomodate the split in sources. Also added more
713 wrapper macros to choose between a system installed error.h or our
714 shipped gnulib error module:
716 * m4/error.c, m4/error.h: Removed.
717 * m4/Makefile.am: Adjust.
718 (pkgincdir): Removed. Use pkgincludedir instead.
719 * m4/module.h, src/main.c: Don't include `m4/error.h'.
720 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
722 * gnulib/m4/progname.c: Imported from CVS gnulib.
723 * gnulib/m4/progname.h: Ditto.
724 * src/main.c: Adjust to use progname module.
725 * gnulib/m4/error.c: Imported from CVS gnulib.
726 * gnulib/m4/error_.h: Ditto.
727 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
728 if appropriate, and link a local error.h if the system version is
730 (libgnu_la_SOURCES) Add progname module sources.
731 * gnulib/config/error.m4: Imported from CVS gnulib.
732 * gnulib/config/strerror_r.m4: Ditto.
733 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
734 to have ERROR_H for Makefile substitutions and tell system.h
735 whether the system error.h should be used, or a locally installed
737 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
739 2003-09-09 Gary V. Vaughan <gary@gnu.org>
741 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
742 s/gettext_.h/gettext.h/.
744 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
745 automake have been fixed.
747 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
748 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
749 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
750 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
752 2003-09-09 Gary V. Vaughan <gary@gnu.org>
754 The gnulib obstack module requires the gnulib gettext module for
755 systems that do not have GNU gettext installed. Because we use
756 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
757 that directory incase it clashes with the system gettext.h. This
758 delta uses gettext_.h and extra rules in the Makefile to make a
759 link to gettext.h when needed:
761 * Makefile.am (auxdir): Removed. No longer used.
762 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
763 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
765 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
766 Makefile based build.
767 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
768 of the macros are kept.
769 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
770 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
771 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
772 distributes these automatically.
773 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
774 warning from automake-1.7a.
775 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
776 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
778 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
779 wrt. m4_FUNC_OBSTACK.
780 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
781 wrt. m4_sys_STACKOVF.
782 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
783 wrt. _m4_LIB_GMP, m4_LIB_GMP.
784 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
785 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
787 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
788 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
789 gettext.h link on deficient systems.
790 (pkginc_HEADERS): Mention $(GETTEXT_H).
791 (EXTRA_HEADERS): Mention gettext.h.
792 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
793 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
794 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
795 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
796 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
797 gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
798 gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
799 gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
800 gnulib/config/po.m4, gnulib/config/progtest.m4,
801 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
802 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
804 2003-09-05 Gary V. Vaughan <gary@gnu.org>
806 We can't mirror the gnulib directory structure here, since we need
807 to be able to eg. `#include <m4/obstack.h>' from our source files,
808 which is much easier if the local obstack.h is created in a
809 directory named m4. Rather than trying to symlink everything into
810 the m4 directory, now we build a libtool convenience library from
811 the sources we get from gnulib and link that with libm4.la:
813 * gnulib/config/extensions.m4: Imported from CVS gnulib.
814 * gnulib/config/unlocked-io.m4: Ditto.
815 * gnulib/m4/unlocked-io.h: Ditto.
816 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
817 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
818 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
819 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
820 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
821 * m4/Makefile.am: Adjust.
822 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
823 macros we redistribute.
824 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
825 library among others.
826 (GNULIB_SRCS, GNULIB_MACROS): Removed.
827 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
828 * config/m4-obstack.m4: Adjust.
829 * po/POTFILES.in: Adjust.
830 * configure.ac: Reformatting. Call newly imported gnulib macros.
831 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
832 bogus calls of `#include "m4.h"'.
833 * Makefile.am: INCLUDES has been deprecated in favour of
835 * m4/Makefile.am: Ditto.
836 * modules/Makefile.am: Ditto.
837 * src/Makefile.am: Ditto.
839 2003-09-05 Gary V. Vaughan <gary@gnu.org>
841 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
843 2003-09-04 Gary V. Vaughan <gary@gnu.org>
845 Migrate the obstack support into the gnulib directories for easy
846 synchronisation with upstream files in gnulib:
848 * config/gnu-obstack.m4: Moved from here...
849 * config/m4-obstack.m4: ...to here.
850 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
851 * m4/obstack.c, m4/obstack_.h: Moved from here...
852 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
853 * po/POTFILES.in: Adjust.
854 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
855 * m4/Makefile.am: Add a whole new section to link the obstack
856 sources from the gnulib tree if necessary.
857 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
859 * config/m4-obstack.m4: Rewrite as a wrapper for
860 gnulib/m4/obstack.m4.
862 2003-09-04 Gary V. Vaughan <gary@gnu.org>
864 GNU M4 currently builds with a number of files adapted from
865 upstream sources. Recently the gnulib project on savannah.gnu.org
866 has pulled together a great many of these externally maintained
867 files. This delta is the beginnings of isolating those files
868 maintained in gnulib to make it easy to synchronise M4 with the
869 upstream files prior to releases.
871 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
873 (SUBDIRS): Added new gnulib subdirectory.
874 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
875 * config/stdbool.m4: Moved from here...
876 * gnulib/m4/stdbool.m4: ...to here.
877 * m4/stdbool_.h: Moved from here...
878 * gnulib/lib/stdbool_.h: ...to here.
879 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
881 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
882 code to work with new stdbool_.h location.
883 (gnulib_srcdir): New.
885 2003-09-04 Gary V. Vaughan <gary@gnu.org>
887 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
888 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
890 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
891 (EXTRA_DIST): Use it.
893 * bootstrap: CVS autoreconf leaves file droppings. Remove
894 aclocal.m4t incase autoreconf doesn't.
896 2003-08-29 Gary V. Vaughan <gary@gnu.org>
898 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
899 the other gnulib imports, renamed to m4/obstack_.h.
900 * m4/obstack.c: Updated from CVS gnulib.
901 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
902 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
903 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
904 about vpath already, and $top_srcdir upsets CVS Automake, so the
905 $top_srcdir reference was removed.
907 * m4/system-h.in: For consistency with the gnulib imports, renamed
909 * m4/Makefile (EXTRA_HEADERS): Adjust.
910 * configure.ac (AC_CONFIG_FILES): Adjust.
912 * m4/stdbool_.h: New file from gnulib for systems without their
914 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
915 * config/stdbool.m4: New file. Macros from gnulib for same.
916 * configure.ac: Use it.
918 2003-08-27 Gary V. Vaughan <gary@gnu.org>

965 * src/getopt1.c: Ditto.
968 * src/stackovf.c: Ditto.
970 * config/gmp.m4 (M4_AC_LIB_GMP): Use AC_INCLUDES_DEFAULT:
971 ac_default_headers is an autoconf internal variable.
972 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
973 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
975 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
976 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
979 2003-08-15 Gary V. Vaughan <gary@gnu.org>
981 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
983 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
984 possible or faking one with a typedef. Changed all callers.
986 2003-08-15 Gary V. Vaughan <gary@gnu.org>
988 Still cleaning up the users' module API, by taking out the stuff
989 that isn't used by any existing modules, and moving specialised
990 functions out of libm4 and into the module they are used by.
992 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
993 * m4/utility.c (m4_skip_space): ...to here the home of its only
994 use, made static and renamed to `skip_space'. Changed all
996 * m4/m4module.h (m4_expand_ranges): Removed prototype.
997 * m4/utility.c (m4_expand_ranges): Moved definition from here...
998 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
1000 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
1002 * modules/gnu.c (builtin_syntax): Import and use in this
1003 builtin implementation.
1004 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
1006 * m4/macro.c (trace_flush): Except here where the macro is now
1008 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
1009 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
1011 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
1012 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
1014 2003-08-14 Gary V. Vaughan <gary@gnu.org>
1016 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
1017 compiler based AC_CHECK_HEADER that was introduced in
1019 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
1020 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
1021 * configure.ac: Use renamed M4_AC_LIB_GMP.
1023 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
1024 macro that requires arguments! This stops the shell's bad
1025 substitution error at configure time.
1027 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
1028 variables to the testsuite shell. Set the value of USE_GMP so
1029 that the gmp test will run!
1030 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
1032 2003-08-11 Gary V. Vaughan <gary@gnu.org>
1034 Libltdl already has an excellent mechanism for accessing C symbols
1035 in modules. Lets use that! Remove all the exporting cruft and
1036 just use lt_dlsym in conjunction with a few conventions to
1037 simplify module writers' jobs. Also removed the table address
1038 caching code and otherwise simplified the module loader quite a
1039 bit. To access exported symbols in other modules, first the
1040 exporting module must name the symbols <modname>_LTX_<symname>,
1041 and the importing module must define a function type called
1042 <symname>_func. The importer then adds
1043 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
1044 that wishes to call out to the exported functions. Care must be
1045 taken that <symname> is non-NULL in the importing module incase
1046 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
1047 definition was in the importers source. Study
1048 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
1049 m4_module_import will attempt to automatically load a module
1050 required for symbol access if it is not loaded already.
1052 * TODO: Removed the items fixed in this delta.
1053 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
1055 * m4/ltdl.h (lt_dlhandle_find): Declare it.
1056 * m4/module.c (m4_module_unload): Use it.
1057 * src/freeze.c (reload_frozen_state): Ditto.
1058 * m4/m4module.h (m4_export): Deleted. Removed all references.
1059 (M4_MODULE_IMPORT): New user convenience macro for importing
1060 arbitrary symbols from other modules.
1061 * m4/module.c (m4_module_import): New function to service
1062 M4_MODULE_IMPORT macro.
1063 (module_data): Removed. Looking up the tables on demand with
1064 lt_dlsym, rather than caching their addresses here simplifies the
1066 (m4_get_module_builtin_table, m4_get_module_macro_table):
1067 Removed. Changed all callers.
1068 (set_module_macro_table, set_module_builtin_table): Renamed to
1069 install_macro_table and install_builtin_table respectively, and
1070 simplified now that the cache is no more.
1071 * modules/gnu.c (builtin_symbols): Use this new mechanism to
1072 import m4_dump_symbols from the m4 module.
1073 (builtin_esyscmd): Likewise for m4_set_sysval and
1075 * modules/m4.c (m4_export_table): Removed. Functions are
1076 addressed with the new mechanism which doesn't need this.
1077 (m4_set_sysval): New exported accessor function to prevent
1078 problems with variable access on inferior architectures.
1079 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
1080 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
1081 that we can have some type safety.
1082 * modules/modtest.c (export_test): C level exported function for
1083 testing the new import mechanism.
1084 * modules/import.c: New file for the import end of the test.
1085 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
1086 * tests/modules.at: New test cases for intermodule symbol
1089 2003-08-07 Gary V. Vaughan <gary@gnu.org>
1091 * m4/m4module.c (m4_string): Moved from here...
1092 * m4/m4private.c (m4_string): ...to here.
1094 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
1096 2003-07-29 Gary V. Vaughan <gary@gnu.org>
1098 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
1099 already available to module writers through
1100 m4_{get,set}_nesting_limit_opt(), so moved from here...
1101 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
1102 (m4_create): Use it.
1104 2003-07-28 Gary V. Vaughan <gary@gnu.org>
1106 Aside from auditing path.c for m4module.h api obfuscation, this
1107 delta introduces the concept of private struct members in opaque
1108 data types to GNU m4: See the STYLE file for details.
1110 * TODO: Remind ourselves that a rewrite of path.c is needed.
1111 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
1113 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
1114 here and renamed. These type definitions are for internal api use
1115 only. Changed all callers.
1116 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
1118 * m4/path.c (search_path_env_init, search_path_add): ...to here
1119 and renamed. These calls were never used outside this file.
1120 Changed all callers.
1121 (dirpath): Moved functionality of this static declaration...
1122 * m4/m4private.h (struct m4): ...to this new internal only
1123 search_path field. Changed all callers.
1124 (m4__get_search_path): Added new internal api accessor.
1125 * m4/path.c (m4_search_path_info_new): Removed. Not used.
1126 (m4_include_init): Removed...
1127 * m4/m4.c (m4_create): ...because the new m4 field is now
1129 (m4_delete): Recycle search_path memory.
1130 * src/main.c (main): Don't call m4_include_init now that it's
1132 * doc/STYLE: Document convention for private fields in opaque
1135 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1137 Sometimes exporting the address of a symbol from a module isn't
1138 enough for other modules to call that symbol correctly. If
1139 custom data types are used for function parameters, they need to
1140 be known to the caller. This change introduces the concept of
1141 $(prefix)/include/modules/$(modulename).h to declare those
1142 structures. Also we move m4_dump_symbols from libm4 to the m4
1143 module to show this concept in action.
1145 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
1146 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
1147 exporting data structures from modules/m4.c.
1148 * modules/m4.c, modules/gnu.c: Include it.
1149 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
1150 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
1152 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
1154 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
1155 ...to here, with slight renaming.
1156 (m4_export_table): Prototype and add m4_dump_symbols.
1157 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
1158 definition of m4_dump_symbols.
1159 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
1160 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
1162 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1164 Create an export table in modules/m4.c in readiness for beefing up
1165 the module loader to track module exports and imports.
1167 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
1168 * m4/debug.c (m4_debug_flush_files): Moved...
1169 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
1170 * modules/gnu.c (builtin_esysval): Use it.
1171 * m4/m4module.h (m4_export): New type for declaring module symbols
1173 * modules/m4.c (m4_export_table): List symbols exported from this
1174 module for use by other modules.
1176 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1178 An experiment: There is loads of code in libm4 which should be in
1179 the m4 module, but is also used by another module. Just because
1180 some linkers won't cope with calls across dynamic runtime loaded
1181 objects I initially left the code in libm4. It will tidy the
1182 module api immensely if this code moves to the right place, I just
1183 need to remember to invent a suitable calling mechanism at some
1184 point. For now, only modules that are statically linked and
1185 preloaded will get this treatment, so the only platforms that will
1186 break are those that require all symbols to be resolved at link
1189 * TODO: Reminder that what I am doing could reduce portability
1190 unless I do something more robust later.
1191 * m4/m4module.h (m4_sysval): No longer exported from libm4.
1192 * m4/utility.c (m4_sysval): No longer declared in libm4.
1193 * modules/Makefile.am: Reformatting.
1194 * modules/m4.c (m4_sysval): Declare it at place of use.
1195 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
1197 2003-07-23 Gary V. Vaughan <gary@gnu.org>
1199 * m4/m4module.h: Reformatting and rearranging lines a bit.
1200 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
1202 (m4_call_macro, m4_expand_input): Renamed...
1203 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
1205 (m4_expansion_level, m4_process_macro): Moved...
1206 * m4/macro.c (expansion_level, process_macro): ...to here, and
1209 * m4/m4module.h (program_name): Not used by modules at all, so
1211 * src/main.c (program_name): ...to here.
1212 (print_program_name): Renamed...
1213 (print_program_name_CB): ...to conform to the STYLE guide.
1215 2003-07-23 Gary V. Vaughan <gary@gnu.org>
1217 More refactoring of the m4module.h API. Replace #defines with an
1218 enum, and move non-public functions out of the public API.
1220 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
1222 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
1223 * m4/debug.c (m4_debug, trace): Moved...
1224 * m4/m4private.h (struct m4): ...to fields of this struct.
1225 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
1227 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
1228 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
1229 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
1230 * m4/m4module.h (m4_context_field_table): Add entries for new
1231 debug_file and trace_messages fields.
1232 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
1233 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)

1239 (m4_trace_format, m4_trace_header, m4_trace_flush)
1240 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
1242 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
1243 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
1244 * m4/macro.c (trace_format, trace_header, trace_flush)
1245 (trace_prepre, trace_pre, trace_post): ...to these newly static
1246 functions, since they are only ever used from this file. Changed
1249 2003-07-17 Gary V. Vaughan <gary@gnu.org>
1251 Change the macros for checking syntax so that matching against
1252 multiple possible syntax classes can be done with a single
1253 comparison some of the time. The various classes are now bits of
1254 an int that can be checked with bitwise logic operators.
1256 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
1257 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)

1266 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
1267 Replace all calls with invocations of these...
1268 (m4_is_syntax, m4_has_syntax): ...New macros.
1269 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
1270 is no longer required with new macros. Changed all callers.
1272 2003-07-15 Gary V. Vaughan <gary@gnu.org>
1274 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
1275 values are returned as part of the internal interface, so they
1277 * m4/private.h: ...to here.
1278 * m4/macro.c (expand_token): Check for out of range
1279 m4_peek_input() results before looking up in the syntax table.
1280 (collect_arguments): Ditto.
1282 * NEWS: Note `$' syntax class.
1284 2003-07-08 Paul Eggert <eggert@twinsun.com> and
1285 Gary V. Vaughan <gary@gnu.org>
1287 Conform to POSIX if the POSIXLY_CORRECT environment is set.
1288 --traditional `define' now smashes all the definitions.
1290 * NEWS: Explain this.
1291 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
1292 (Extensions): Explain that extensions that are incompatible with
1293 POSIX are disabled if POSIXLY_CORRECT is set.
1294 (Incompatibilities): Remove.
1295 (Define, Other Incompat): Explain difference
1296 between GNU and POSIX behavior of define, pushdef, popdef.
1297 * m4/m4.c (m4_get_posixly_correct_opt): New undef.

1320 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
1321 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
1322 * m4/input.c (init_builtin_token): Comment typo.
1323 (m4__next_token): Comment typo.
1324 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
1325 by using the new M4__IS_STRING macro.
1326 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
1327 variable references in macro expansions.
1329 * doc/m4.texinfo (Eregexp and Regexp): Typo.
1330 (Epatsubst and Patsubst): Typo.
1333 2003-06-26 Gary V. Vaughan <gary@gnu.org>
1335 Move the global variables that pertain to syntax to a new `struct
1336 m4_syntax_table', and then add one of these to `struct m4'. The
1337 ripple effect through the code to both change formerly global
1338 references, and make sure a suitable context is available in
1339 lexical scope is disproportionately large compared to the size of
1340 the change proper. This change is a large part of decoupling
1341 syntax.c from the rest of the code that uses it.
1343 * m4/m4private.h (struct m4): Add a syntax field.
1344 * m4/m4.c (m4_create): Initialise it,
1345 (m4_delete): Recycle it.
1346 (m4_get_symtab): Remove hand coded version...
1347 (m4_get_symbol_table): ...and generate this with cpp. Changed all
1349 * m4/m4module.h (m4_context_field_table): Add an extra field so we
1350 can generate m4_get_symbol_table. Add a new row for
1351 m4_get_syntax_table.
1352 (M4SYNTAX): Syntactic sugar for module writers.
1353 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
1354 (m4_syntax_table): New home for syntax related formerly global
1356 * m4/m4private.h (struct m4_syntax_table): Define it.
1357 * m4/input.c (m4_input_init): Initialisation of these formerly
1358 global variables moved...
1359 * m4/syntax.c (m4_syntax_create): ...to here.
1360 * m4/input.c (m4_input_exit): And similarly, recycling of the
1361 memory used by those values moved...
1362 * m4/syntax.c (m4_syntax_delete): ...to here.
1363 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
1364 Moved to m4/m4private.h.
1365 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
1366 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
1367 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
1368 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
1369 objects. Changed all callers that used to directly access the
1371 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
1372 Removed and incorporated into m4_syntax_table structure.
1373 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
1374 * m4/syntax.c (m4_set_syntax): Now returns an error status,
1375 instead of requiring a `struct m4' to generate its own errors.
1376 Changed all callers.
1377 * src/main.c (main): Now that the syntax table is initialised as
1378 part of m4_create, we have to manually wipe the syntax entries if
1379 we are about to read a frozen file.
1381 2003-06-26 Gary V. Vaughan <gary@gnu.org>
1383 * doc/STYLE: Added notes on callback naming schemes.
1385 * m4/module.c (m4_set_module_macro_table)
1386 (m4_set_module_builtin_table): Declarations weren't changed when
1387 definitions were renamed on 2003-06-19.
1389 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
1390 neither used nor particularly appropriate since it exposes the
1391 internal workings of the hash module. I haven't yet decided
1392 whether to remove it entirely.
1394 2003-06-20 Gary V. Vaughan <gary@gnu.org>
1396 Two related changes, and a huge knockon effect throughout the
1397 source: Moved the option variables out of global space and into
1398 `struct m4'; made `m4_symtab' a real datatype, so that its api
1399 is not marred passing `struct m4' around just so it can decide
1400 whether to keep traced symbol names or not. Added setters and
1401 getters for the formerly global option variables, and obviously
1402 changed a vast number of functions to take a `struct m4' and use
1403 the getter funcs to find option values.
1405 * m4/utility.c (interactive, sync_output, debug_level)
1406 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
1407 (max_debug_argument_length, warning_status, nesting_limit)
1408 (discard_comments): Removed.
1409 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
1410 (debug_level, max_debug_argument_length, prefix_all_builtins)
1411 (suppress_warnings, discard_comments, interactive, sync_output):
1412 Removed from here...
1413 * m4/m4private.h (struct m4): ...and equivalent fields added to
1415 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
1416 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
1417 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
1418 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
1419 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
1420 macros for the new fields.
1421 * m4/m4module.h (m4_context_field_table)
1422 (m4_context_opt_bit_table): Helper macros used to generate
1423 prototypes, setters and getters for new option fields
1425 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
1426 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
1427 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
1428 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
1429 (m4_get_interactive_opt, m4_get_sync_output_opt)
1430 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
1431 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
1432 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
1433 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
1434 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
1435 setter and getter functions generated by cpp from
1436 m4_context_field_table and m4_context_opt_bit_table, exported as
1437 part of the module api. Changed all callers.
1438 * m4/symtab (struct m4_symtab): Used as the concrete type for
1440 (m4_symtab_create): Allocate and initialise a new struct.
1441 (m4_symtab_apply): New function that works like m4_hash_apply, but
1442 with different callbacks specific to symbol tables. Changed all
1444 (symbol_destroy, arg_destroy, arg_copy): Renamed
1445 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
1446 they have unused parameters for a reason!
1447 (dump_symbol_CB): New callback to dump the contents of a single
1449 (symtob_dump): Rewritten in terms of dump_symbol_CB.
1450 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
1451 Changed all callers.
1452 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
1453 of the contained `m4_symtab' at the `no_gnu_extensions' field.
1454 Although I'm not convinced these semantics are correct, they are
1455 at least consistent with how things were before this delta. Also
1456 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
1458 2003-06-19 Gary V. Vaughan <gary@gnu.org>
1460 Tie down the interface to libm4 some more. Make more structures
1461 opaque to modules by moving them to m4private.h, and writing
1462 setters and getters. To win back the speed penalty for doing this
1463 also wrote macroized versions that do know about structure layout
1464 in m4private.h and #include that file into modules when NDEBUG is
1465 defined at compile time. There are still some accessor macros in
1466 m4private.h that need to go, but that is not necessary to clean
1469 * m4/m4module.h (m4_symbol_type): Moved...
1470 * m4/m4private.h (m4__symbol_type): ...to here.
1471 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
1472 (m4_set_symbol_traced, m4_set_symbol_name_traced)
1473 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
1474 (m4_get_symbol_func, m4_symbol_value_create)
1475 (m4_symbol_value_delete, m4_set_symbol_value_text)
1476 (m4_set_symbol_value_func): New exported api to symbols.
1477 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
1478 and m4_is_symbol_value_func.
1479 * m4/m4module.h: Prototype these guys.
1480 * m4/module.c (m4_set_module_macro_table)
1481 (m4_set_module_builtin_table): Make these static, there is no
1482 reason to pollute the api with them.
1483 * m4/m4private.h: Reformatting.
1484 (m4_get_symtab): Only define when NDEBUG is defined.
1485 (m4_get_symbol_value, m4_get_symbol_traced)
1486 (m4_set_symbol_traced, m4_set_symbol_name_traced)
1487 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
1488 (m4_get_symbol_func, m4_symbol_value_create)
1489 (m4_symbol_value_delete, m4_set_symbol_value_text)
1490 (m4_set_symbol_value_func): Macro implementations of the new
1491 functions when NDEBUG is defined.
1492 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
1493 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
1494 Superceded by the above. All callers changed.
1495 (M4ARG): Removed. This is no longer different to the
1496 m4/m4module.h definition.
1497 * modules/gnu.c, modules/m4.c: Only include m4private.h when
1498 NDEBUG is defined. That way we exercise the same (albeit slower)
1499 api that external modules must use.
1501 2003-06-18 Gary V. Vaughan <gary@gnu.org>
1503 Renamed some of the types and their accessors to make more sense.
1504 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
1505 has a stack of SYMBOL_VALUEs.
1507 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
1508 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
1509 m4_get_symbol_value_type, m4_get_symbol_value_text,
1510 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
1511 Changed all callers.
1512 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
1513 (m4_get_token_type): Renamed
1514 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
1515 to the internal api.
1516 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
1518 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
1519 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
1520 (m4__token_type): Moved here from m4module.h.
1521 (m4__next_token): Renamed from m4_next_token.
1522 * m4/symtab.c: Removed some of the parameterised macro support
1523 functions for modularisation later.
1524 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
1525 m4_hash_dup to perform a true deep copy of the SRC.
1526 (arg_copy): Callback for m4_symbol_value_copy.
1527 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
1528 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
1529 m4_get_symbol_value_func. Changed all callers.
1531 2003-06-18 Gary V. Vaughan <gary@gnu.org>
1533 Tidy up style of hash.[ch] in accordance with doc/STYLE.
1535 * m4/hash.c: Internal symbol renaming and formatting.
1536 (m4_hash_dup): New function to facilitate deep copies of hash
1538 (m4_hash_apply_func): Returns a void* now, which is a richer type
1539 for returning exceptions (NULL means keep going).
1540 (m4_hash_apply): Ditto.
1541 * m4/hash.h: Declare exported symbols with an explicit extern.
1544 2003-06-17 Gary V. Vaughan <gary@gnu.org>
1546 Still refactoring furiously. This delta represents a change in
1547 semantics to symtab.c. Instead of building temporary m4_tokens
1548 in the caller, and copying fields in the methods, we now create
1549 the actual m4_token for hashing in the caller so the methods just
1550 slot them in directly. Also, this means that we don't lookup a
1551 symbol and get back an allocated but VOID token to copy fields
1552 into, we create the token we want to push and pass that to
1553 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
1554 a few other small changes to stop knowledge of the implementation
1555 of symtab.c leaking out into other files.
1557 * m4/macro.c (expand_argument): Comment typo corrected.
1558 * m4/symtab.c (symtab_fetch): New function to fetch the address of
1560 (m4_symbol_pushdef): Take an extra value parameter and use this
1561 directly as the new top of the value stack. All callers changed
1562 to build a token and pass responsibility for memory in, rather
1563 than copying as we used to.
1564 (m4_symbol_define): Also use the new value parameter directly as a
1565 replacement for the top of the value stack. All callers changed
1566 to build a token as above.
1567 (m4_set_symbol_traced): New function to set the traced bit on the
1568 named symbol, creating it if necessary.
1569 (symbol_popval): The guts of the old m4_symbol_popdef.
1570 (m4_symbol_popdef): Use it.
1571 * m4/builtin.c (m4_symbol_set_token): Removed,
1572 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
1574 * m4/module.c (m4_set_module_builtin_table)
1575 (m4_set_module_macro_table): ...with these more orthogonal
1577 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
1578 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
1580 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
1581 (m4_arg_signature_parse): Moved...
1582 * m4/symtab.c: ...to here.
1583 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
1584 screw something up. Moved...
1585 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
1586 actually does a proper deep copy of source to dest.
1588 2003-06-16 Gary V. Vaughan <gary@gnu.org>
1590 Further refactoring to stabilise the module API. Renaming some
1591 functions for orthogonality, and judicious definition migration to
1592 move things out of the set of exported symbols.
1594 * doc/STYLE: New file. Notes on coding style.
1595 * m4/m4module.c: Updated bitrotted docucomment at the top of the
1597 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
1598 m4_get_module_name, m4_get_module_builtin_table,
1599 m4_get_module_macro_table which are verb phrases. Changed all
1601 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
1603 * m4/module.c (m4_set_module_builtin_table)
1604 (m4_set_module_macro_table): ...here, and renamed. Changed all
1606 * m4/m4module.c (m4_module_data): This...
1607 * m4/m4private.c (struct m4_module_data): ...and this...
1608 * m4/module.c (module_data) ...consolidated here and no longer
1609 exported. Changed all callers.
1611 2003-06-16 Gary V. Vaughan <gary@gnu.org>
1613 Begin work on lifting the curse of the global variables. To start
1614 with create a `struct m4' context container, and replace
1615 `m4__symtab' with `context->symtab' throughout. This means
1616 initialising a context container in main, and adjusting many
1617 functions between main and the module entry points so that the
1618 container gets passed through. It would have been nice to
1619 defer this until after 1.5, but it has a major effect on the
1620 user's module writing ABI, so it needs to be addressed now - at
1621 least in the areas that impact the ABI. An interrelated change
1622 in the symtab API removes the dependency on a global symbol table,
1623 and instead focuses on a passed table (from the context
1626 * TODO: Reminders for finishing context functionality.
1627 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
1628 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
1629 global variables and eventually allow m4 to be reentrant.
1630 * m4/m4private.h (m4): Define the new structure here...
1631 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
1632 don't carry the overhead of a function call.
1633 * m4/m4module.h: Prototype extern functions from m4/m4.c.
1634 (m4): Declare type for new struct m4 objects.
1635 (M4SYMTAB): User macro to ease finding the symbol table for the
1636 current context for module developers.
1637 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
1639 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
1640 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
1641 (m4_call_macro, m4_dump_symbols, m4_expand_input)
1642 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
1643 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
1644 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
1645 m4* context parameter. Changed definitions and all callers.
1646 (m4_symtab): Alias for m4_hash to decouple the
1647 m4_symtab api from m4_hash.
1648 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
1650 (m4_symtab_create): New function to return an initialised
1652 (m4_symtab_delete): New function to delete an m4_symtab's memory.
1653 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
1654 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
1655 instead of simply using the global m4__symtab. Changed
1656 definitions and all callers.
1657 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
1658 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
1659 * src/main.c (main): Create a context and use that instead of the
1660 former global m4__symtab.
1662 2003-06-13 Gary V. Vaughan <gary@gnu.org>
1664 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
1665 to the callback. Callbacks should not need to hardcode the
1666 hashtable they are working from, nor should we have to waste the
1667 userdata parameter to pass the table in.
1668 * m4/hash.h (m4_hash_apply_func): Require the initial table
1670 * m4/symtab.c (symtab_destroy): Use the passed table instead
1671 of hardcoding m4__symtab.
1672 (m4_symbol_popdef): Don't use the userdata parameter to pass the
1673 table to arg_destroy.
1674 (arg_destroy): Use the hash parameter, ignore userdata.
1675 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
1677 (traceon, traceoff): Call set_trace with the extra initial
1680 2003-06-13 Gary V. Vaughan <gary@gnu.org>
1682 More refactoring to stabilise the module api, this time for
1683 symtab.c. Additionally, start to pay attention to function names
1684 that don't contain a verb like they should.
1686 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
1687 wrapper for m4_hash_apply to decouple the symtab module from the
1689 (m4_symbol_builtin, m4_symbol_macro): Renamed to
1690 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
1692 (m4_symbol_delete): Create a macro version to save a function
1694 (m4_token_t, m4_data_t): These violate the POSIX reserved
1695 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
1697 (m4_token_type): Renamed to m4_token_get_type.
1698 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
1699 (m4_symtab_exit): Removed from the exported module
1701 * m4/m4private.h (m4__symtab, m4__symtab_init)
1702 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
1703 renamed and added to the internal api. Changed all callers.
1704 (m4_symtab_apply): A faster macro version of the function for
1705 users of the internal api.
1706 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
1707 symbol_destroy and arg_destroy.
1708 (symtab_debug): Added a prototype.
1709 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
1710 so that callers in this file get the faster macro versions from
1713 2003-06-12 Gary V. Vaughan <gary@gnu.org>
1715 Refactoring modules to rationalise the API into an external
1716 documented (eventually!) API for use by modules in the `m4_'
1717 namespace declared in m4/m4module.h, an internal API between the
1718 source files we ship (including our shipped modules) in the `m4__'
1719 namespace declared in m4/m4private.h and making the rest as
1720 cohesive as possible with liberal use of the `static' keyword.
1721 This change represents an audit to m4/module.c along these
1724 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
1725 Removed. No longer used.
1726 (m4_module_close): Removed prototypes.
1727 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
1728 from the exported module api...
1729 * m4/m4private.h (m4__module_init, m4__module_open)
1730 (m4__module_exit): ...and renamed and added to the internal api.
1731 Changed all callers.
1732 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
1733 Centralised definitions after renaming...
1734 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
1735 (M4_FINISH_SYMBOL): ...and removing from here.
1736 (m4_module_dlerror, m4_module_remove, m4_module_close)
1737 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
1738 module_remove, module_close and caller_id.
1739 (MODULE_SELF_NAME): New macro to make reporting self errors
1741 (m4_module_load, module_close, module_remove): Use it.
1742 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
1744 * src/main.c (main): Use it.
1746 2003-06-12 Gary V. Vaughan <gary@gnu.org>
1748 * README: Remove references to --enable-changeword, which has been
1749 removed from the code.
1751 2003-06-11 Gary V. Vaughan <gary@gnu.org>
1753 Getting rid of the annoying bug with configure --enable-debug,
1754 which spewed -e: command not found errors. This was an interaction
1755 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
1756 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
1757 branch-1-5) to get the full fix.
1759 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
1760 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
1761 and then use the probed value of $SED.
1762 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
1763 this, it messes up the AC_REQUIRE stack.
1765 2003-06-10 Gary V. Vaughan <gary@gnu.org>
1767 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
1768 the destroy callback.
1769 (m4_arg_destroy): Use the hash address to free the hash node key
1772 2003-06-06 Gary V. Vaughan <gary@gnu.org>
1774 First cut at formal parameters in macros.
1776 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
1777 * m4/xstrzdup.c: New file.
1778 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
1779 associative array of parameter names to details.
1780 (m4_symbol_token): Capture macro names with parameter lists.
1781 (m4_arg_signature_parse): And build an associative array to hang
1782 from the symbol structure to map names to details.
1783 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
1784 m4_hash_resize idiom. Now that we potentially add a little hash
1785 table to many of the entries in the symbol table, added an extra
1786 arg to set the initial size. Changed all callers.
1787 (m4_hash_apply): New function that is basically a generalised
1789 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
1790 all callers to call m4_hash_apply instead.
1791 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
1792 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
1793 m4_arg_signature association that might be attached to the symbol,
1794 * m4/hash.h (m4_hash_apply_func): Replacement type for...
1795 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
1796 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
1798 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
1799 (M4_IS_IDENT): Detect characters that can be safely used in
1801 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
1802 * m4/macro.c: Corrected grammar in some comments. Use `token'
1803 rather than `td' for m4_token variables.
1804 (m4_process_macro): If we find a dollar followed by some
1805 M4_IS_IDENT characters, replace that with the contents of the argv
1806 entry with offset stored in the m4_token_arg associated with the
1807 collected identifier.
1809 2003-06-05 Gary V. Vaughan <gary@gnu.org>
1811 Begin preparations for supporting formal parameters in m4 macros.
1813 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
1814 the details of a formal parameter.
1815 (m4_token): Add an arg_signature member to hold a hash table for
1816 looking up formal parameters.
1817 * m4/input.c: Update more bitrotted comments.
1818 (m4_push_builtin): Initialise arg_signature member.
1819 (init_builtin_token): Copy arg_signature member.
1820 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
1821 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
1823 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
1824 (m4_macro_pushdef, m4_macro_define): ...these, And...
1825 (m4_symbol_token): ...wrapped around this new function, which
1826 vastly simplifies the arguments required by the functions it
1828 Changed all callers.
1830 2003-06-05 Gary V. Vaughan <gary@gnu.org>
1832 * m4/macro.c: Format changes.
1834 2003-06-04 Gary V. Vaughan <gary@gnu.org>
1836 * m4/input.c: Updated various bitrotted comments.
1837 (m4_push_builtin): Just pass the whole m4_token, rather than
1838 extracting all the fields in the caller. This also allows us to
1839 check the token type for consistency.
1840 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
1841 Renamed to builtin_funcs, builtin_peek, builtin_read,
1842 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
1843 the code. Changed all callers.
1844 (struct input_block): Similarly renamed u_m member to u_b, and
1845 changed all callers.
1846 (m4_next_token): Use bzero to initialise the data fields.
1847 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
1849 2003-05-29 Gary V. Vaughan <gary@gnu.org>
1851 These changes were necessary to get m4 to build on my iBook
1852 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
1853 (GCC) 3.1 20020420 (prerelease)":
1855 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
1856 inclusion of module loader headers.
1857 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
1858 * m4/Makefile.am: Ditto.
1859 (libm4_la_LIBADD): Added $(LTLIBINTL).
1860 * m4/utility.c (program_name): Removed declaration in favour of
1861 the one already in error.c!
1862 * m4/m4module.h (program_name): Define to program_invocation_name
1863 when using GNU C library. Use an explicit extern declaration.
1864 (interactive, sync_output, debug_level, hash_table_size)
1865 (no_gnu_extensions, prefix_all_builtins, max_debug_argument_length)
1866 (suppress_warnings, warning_status, nesting_limit, discard_comments)
1867 (lquote, rquote, bcomm, ecomm, m4_bad_argc, m4_skip_space)
1868 (m4_numeric_arg, m4_shipout_int, m4_shipout_string, m4_dump_args)
1869 (m4_debug, m4_debug_init, m4_debug_exit, m4_debug_decode)

1874 (m4_current_line, m4_current_diversion, m4_output_current_line):
1875 Don't rely on default, use an explicit extern.
1876 * m4/error.h (error, error_at_line, error_print_progname)
1877 (error_message_count, error_one_per_line): Ditto.
1878 * m4/ltdl.c: Update from CVS libtool.
1880 * commit: Update from CVS cvs-utils.
1882 2002-11-04 Akim Demaille <akim@epita.fr>
1884 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
1886 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
1888 2002-11-04 Akim Demaille <akim@epita.fr>
1890 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
1892 2002-11-04 Akim Demaille <akim@epita.fr>
1894 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
1895 used as `external', and Libtool 1.4.3.
1897 (LTLIBOBJS): Don't play with it.
1899 * Makefile.am (SUBDIRS): Remove intl.
1900 (ACLOCAL_AMFLAGS): Add -I config.
1901 (EXTRA_DIST): Add config/config.rpath.
1904 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
1906 2002-05-29 Gary V. Vaughan <gary@gnu.org>
1908 Preparations for refactoring syntax tables to allow reverse
1909 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
1910 speed of normal lookups in an array of unsigned short.
1912 * m4/input.c (single_quotes, single_comments, use_macro_escape):
1914 * m4/m4private.h (m4__single_quotes, m4__single_comments,
1915 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
1916 is for internal symbols which unavoidably pollute the global
1917 namespace, but are not published APIs.
1918 Adjusted all callers.
1919 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
1920 m4_set_comment, m4_set_syntax, set_syntax_internal,
1921 unset_syntax_attribute): Moved from this file...
1922 * m4/syntax.c: New. ...to this file.
1923 Also added an m4_syntax_exit stub for orthogonality.
1924 * src/main.c (main): Use it.
1925 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
1926 * m4/m4module.h: Reformatting. New prototypes.
1928 2002-05-29 Gary V. Vaughan <gary@gnu.org>
1930 * bootstrap (aclocal_apiversion): The aclocal apiversion is
1931 distinct from the automake release number (in that the apiversion
1932 apparently has no micro-version-component).
1933 (aclocal_apilibdir): Use it.
1935 2002-05-28 Gary V. Vaughan <gary@gnu.org>
1937 * m4/hash.c (m4_hash_resize): New function.
1938 * m4/hash.h: Add prototype.
1939 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
1940 benchmarking to find a good value for, say, autoconf. This is
1941 already a little quicker than before for me.
1943 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
1944 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
1946 * m4/hash.h: Adjust prototypes.
1948 2002-01-22 Akim Demaille <akim@epita.fr>
1950 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
1952 * tests/Makefile.am (package.m4): New.
1953 * tests/atlocal.in: Adjust to CVS Autotest.
1954 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
1955 * configure.ac: LIBOBJ is a forbidden string.
1956 Simplify AM_INIT_AUTOMAKE invocation.
1957 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
1960 2001-10-19 Akim Demaille <akim@epita.fr>
1962 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
1964 2001-10-19 Akim Demaille <akim@epita.fr>
1966 * m4/input.c (m4_next_token): Display where was opened what is
1969 2001-10-19 Akim Demaille <akim@epita.fr>
1971 * m4/macro.c (expand_argument): Display where was opened what is
1974 2001-10-18 Akim Demaille <akim@epita.fr>
1976 * m4/input.c, modules/m4.c: Formatting changes.
1978 2001-10-17 Gary V. Vaughan <gary@gnu.org>
1980 * bootstrap: s/configure.in/configure.ac/
1982 2001-10-16 Gary V. Vaughan <gary@gnu.org>
1984 * m4/symtab.c (m4_symbol_destroy): This function calls
1985 m4_symbol_popdef, which recycles a symbols memory when the last
1986 definition is popped. Since we were passing the address of the
1987 symbol name found in the symbol table, and it was being removed
1988 partway through m4_symbol_destroy() we were referencing freed
1989 memory for the balance of the function. Now we take a copy of the
1990 symbol name tring and use that as a key into the symbol
1991 table... that way if the original symbol name is freed, the copy
1994 2001-10-13 Akim Demaille <akim@epita.fr>
1996 * m4/ltdl.c: Update.
1998 2001-10-13 Akim Demaille <akim@epita.fr>
2000 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
2001 Don't gettextize internal error messages.
2003 2001-10-13 Akim Demaille <akim@epita.fr>
2005 * tests/macros.at (Arity and defn): New failing test.
2006 (Arity, defn, and freeze): New.
2008 Fix `Arity and defn'.
2010 * m4/input.c (m4_push_macro): Don't forget the arity.
2011 * modules/m4.c (defn): Likewise.
2013 2001-10-13 Akim Demaille <akim@epita.fr>
2015 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
2017 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
2018 (Propagation of traceon, Propagation of --trace): this new file.
2020 2001-10-13 Akim Demaille <akim@epita.fr>
2022 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
2023 interface instead of (name, argc...).
2024 Upon failure, specify which argument was guilty.
2027 2001-10-13 Akim Demaille <akim@epita.fr>
2029 * modules/evalparse.c: Save translators' time: don't translate
2030 internal error messages.
2031 (m4_evaluate): Simplify/normalize error messages.
2032 * doc/m4.texinfo (Eval): Adjust.
2034 2001-10-13 Akim Demaille <akim@epita.fr>
2036 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
2037 where no checking is needed.
2038 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
2039 interface instead of (name, argc...).
2041 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
2044 2001-10-13 Akim Demaille <akim@epita.fr>
2046 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
2047 exclude the builtin name from the count.
2048 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
2049 calling ifelse with a single argument is valid.
2050 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
2051 with 1 and 2 args, mostly to strengthen the test suite.
2053 2001-10-13 Akim Demaille <akim@epita.fr>
2055 * m4/output.c (m4_make_diversion, m4_insert_file)
2056 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
2058 2001-10-12 Gary V. Vaughan <gary@gnu.org>
2060 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
2061 since we call these things builtins in the rest of the code!
2063 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
2065 2001-10-12 Gary V. Vaughan <gary@gnu.org>
2067 Rather than forcing each builtin definition to manage its own
2068 argument range checking, tabulate the maxima and minima for all
2069 builtins in each module. This forces us to consider what the
2070 valid ranges for each builtin should be, and moves the checking
2071 code out of each builtin implementation and into the builtin
2072 caller infrastructure.
2074 * m4/m4module.h (struct m4_builtin): Add argument minima and
2076 * m4/m4private.h (struct m4_token): Reflect them here too.
2077 * m4/input.c (struct input_block): ...and here.
2078 (m4_token_copy): New function for token copying.
2079 (init_macro_token): Copy them from a token to the input stack.
2080 (m4_next_token): Don't forget to initialise them for text
2082 * m4/macro.c (expand_argument): Use m4_token_copy, and also
2083 check argument counts before calling the builtin handler.
2084 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
2085 (m4_symbol_macro): Likewise.
2086 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
2087 parameters. Updated all callers.
2088 (m4_builtin_define): Ditto.
2089 (m4_macro_pushdef, m4_macro_define): Ditto.
2090 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
2091 * modules/evalparse.c: Declare argument counts for defined
2092 builtins and remove explicit calls to m4_bad_argc().
2093 * modules/gnu.c: Ditto.
2094 * modules/load.c: Ditto.
2095 * modules/m4.c: Ditto.
2096 * modules/modtest.c: Ditto.
2097 * modules/mpeval.c: Ditto.
2098 * modules/perl.c: Ditto.
2099 * modules/shadow.c: Ditto.
2100 * modules/stdlib.c: Ditto.
2101 * modules/time.c: Ditto.
2104 2001-10-10 Gary V. Vaughan <gary@gnu.org>
2106 The trace semantics now attach the trace bit to a symbol name.
2107 For as long as a traceon(`foo') is active, calls to foo will be
2108 traced regardless of intervening undefines or module unloads.
2109 Fixed the flag propogation issues differently to the fixes
2110 reverted with the last attempt at nailing down trace:
2112 * m4/m4private.h: This file is not visible outside of the m4
2113 source tree, so I removed all the `M4_' and `m4_' prefixes to save
2114 on typing. Updated all clients.
2115 (m4_token): New typedef contains the fields that need to be passed
2116 around with the low level tokeniser.
2117 (m4_token_data): Removed.
2118 (m4_symbol): Now contains the traced flag again.
2119 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
2120 the trace bit set. This change is contained entirely within this
2121 module and doesn't leak out into the callers. Updated all
2123 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
2124 new fields in m4_token. Updated all clients.
2125 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
2126 that `groks_macro_args' and `blind_if_no_args' flags are retained
2127 when defn() results are passed around in m4 code. Updated all
2129 (m4_builtin_define): Ditto.
2130 (m4_macro_pushdef, m4_macro_define): Ditto.
2131 * m4/input.c (struct input_block): Add a flags field to facilitate
2133 (m4_push_macro): ...use it.
2134 (init_macro_token): Retrieve it.
2135 (m4_next_token): Initialise it.
2136 * m4/macro.c (expand_argument): Copy it.
2137 * m4/m4module.h: Adjust.
2138 * tests/builtins.at: Adjust the expected output of the trace
2139 tests to reflect the change in semantics.
2140 * tests/modules.at (modules: trace): Check that unloading a
2141 module which supplies a traced symbol definition doesn't lose te
2144 2001-10-07 Gary V. Vaughan <gary@gnu.org>
2146 * modules/gnu.c (m4_macro_table): Display the timetamp when
2147 expanding __m4_version__.
2149 * configure.ac (--with-modules): Forgot a comma in the
2150 AC_HELP_STRING parameter list.
2152 2001-10-05 Gary V. Vaughan <gary@gnu.org>
2154 * bootstrap: Remove aclocal.m4t when it is no longer required.
2156 2001-10-05 Akim Demaille <akim@epita.fr>
2158 * tests/Makefile.am: Adjust for gnuprog2.
2159 * tests/m4.in: There can be a leading path.
2160 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
2161 * tests/testsuite.at: Adjust to the most recent Autotest.
2162 (AT_CHECK_M4_FILTER): Fix and rename as...
2164 * tests/others.at: Use it.
2166 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
2167 variable in shell scripts, one uses `$'...
2169 2001-10-04 Gary V. Vaughan <gary@gnu.org>
2171 * configure.ac: `rm -f $m4_getopt_h' was lost.
2173 2001-10-04 Gary V. Vaughan <gary@gnu.org>
2175 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
2176 time. Define it for config.h in order to...
2177 * src/main.c (main): ...display the timestamp for --version.
2179 2001-10-04 Akim Demaille <akim@epita.fr>
2181 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
2182 previous builtins `regexp' and `patsubst'.
2183 (regexp, patsubst): Use them.
2184 (eregexp, epatsubst): New builtins.
2185 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
2186 (Epatsubst and Patsubst, Eregexp and Regexp): these.
2187 (Extensions): More info on REs.
2189 2001-10-04 Akim Demaille <akim@epita.fr>
2191 * modules/modtest.c (init_handler): Consistently output to stderr.
2192 (finish_handler): New.
2193 (test): The `if' is an `assert'.
2194 * tests/modules.at: Adjust.
2196 2001-10-04 Akim Demaille <akim@epita.fr>
2198 * m4/utility.c (m4_bad_argc): Detail the mismatches.
2200 2001-10-01 Akim Demaille <akim@epita.fr>
2202 * tests/generate.awk: Tag the tests with `documentation'.
2203 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
2204 Use the make the existing modtest tests more uniform, and complete
2205 the set of possibilities.
2207 2001-10-01 Akim Demaille <akim@epita.fr>
2209 * config/gmp.m4: Consult the user before using GMP: use
2211 * configure.ac: Adjust.
2212 * modules/gmp.c: No protection needed as the module is not built
2215 2001-10-01 Akim Demaille <akim@epita.fr>
2217 * tests/generate.awk: Remove debugging code.
2218 (fatal): Specify the current location.
2220 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
2221 * modules/gnu.c, modules/m4.c: Use M4ARG.
2223 2001-10-01 Akim Demaille <akim@epita.fr>
2225 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
2226 (m4_regexp_compile): New.
2227 (regexp, patsubst): Use it.
2229 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2231 Reinstate the memory handling improvements from the patch I just
2232 reverted. Relevant ChangeLog entries repeated here:
2234 * m4/module.c (m4_module_remove): New function that holds the core
2235 of the old m4_module_unload.
2236 (m4_module_unload): Use it.
2237 (m4_module_unload_all): When we know the modules will never be
2238 used again (i.e. on exit), free up as much module memory as
2239 possible. There are still some artifacts from resident modules
2240 living inside ltdl.c, but everything else is freed.
2241 * m4/debug.c (m4_debug_exit): Free memory allocated in
2243 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
2244 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
2245 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
2246 * m4/m4module.h: Updated prototypes.
2247 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
2248 * m4/hash.h: Updated prototypes.
2249 * src/main.c (main): Use all these new functions to clean up as
2250 much memory as possible before exit.
2252 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2254 Reverted my large patch for removing the old m4_symbol
2255 structure on 2001-09-20. We are still not happy about the way
2256 trace works in conjunction with defn and undefine, and leaving
2257 the reverted patch active prevents us from moving the traced
2258 bit from the definition back to the symbol.
2260 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2262 * configure.in: Moved to...
2263 * configure.ac: ...here. Added a libtool like timestamped
2264 banner, and tidied up the libltdl cruft.
2265 * config/mkstamp: Script to extract a timestamp from ChangeLog.
2266 * modules/Makefile.am (INCLTDL): Removed. This is required
2267 only when libltdl is configured in a subdirectory.
2268 * src/Makefile.am: Ditto.
2269 (LIBADD_DL): No need to add this again, libtool already knows
2270 that libm4.la depends on it.
2271 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
2274 * TODO: stackovf.c is basically broken.
2275 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
2277 2001-09-28 Akim Demaille <akim@epita.fr>
2279 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
2281 2001-09-27 Akim Demaille <akim@epita.fr>
2283 * tests/m4.in: Don't use short options.
2284 Simplify the stderr signature normalization.
2286 2001-09-27 Akim Demaille <akim@epita.fr>
2288 tests/m4 shall be position independent.
2292 * tests/testsuite.at: No args to AT_INIT.
2293 * configure.in, tests/Makefile.am: Adjust.
2295 2001-09-22 Akim Demaille <akim@epita.fr>
2297 Autotest has changed again.
2299 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
2300 (package.m4): Remove.
2301 * configure.in: Adjust to LIBADD_GMP.
2303 2001-09-21 Gary V. Vaughan <gary@gnu.org>
2305 * config/gmp.m4 (AC_ARG_WITH): Removed.
2306 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
2307 (AC_LIB_GMP): When performing a test compile against libgmp,
2308 include the header gmp.h if possible, and link against -lgmp. If
2309 they both work define USE_GMP.
2310 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
2311 (mpeval_LTX_init_func): Complain on load that there was no libgmp
2314 2001-09-20 Gary V. Vaughan <gary@gnu.org>
2316 * m4/evalparse.c: Moved to...
2317 * modules/evalparse.c: ...here. This code is shared between
2318 modules/mpeval.c and modules/m4.c, so there is no need to pollute
2319 the libm4 API with its details. Moderately rewritten to interface
2320 into its clients more simply.
2321 * m4/eval.c: Deleted. Migrated functionality to...
2322 * modules/m4.c: ...here.
2323 (builtin_eval): Implemented in terms of the new interface style.
2324 * modules/mpeval.c (builtin_mpeval): Ditto.
2325 * m4/m4module.h: Removed references to the former m4/eval.c.
2326 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
2327 (EXTRA_libm4_la_SOURCES): Deleted.
2328 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
2329 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
2331 2001-09-20 Akim Demaille <akim@epita.fr>
2333 * config/gmp.m4 (AM_WITH_GMP): Rename as...
2335 By default, use gmp.
2337 * configure.in: Adjust.
2338 Use Automake conditionals for USE_GMP.
2339 Always compute sizeof (long long int).
2340 This was a bug BTW, as `eval' (not `mpeval') depends on it:
2341 before, it was used _only_ if mpeval was not activated.
2342 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
2343 (mpeval_la_LIBADD): New macros.
2344 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
2346 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
2347 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
2350 2001-09-20 Akim Demaille <akim@epita.fr>
2352 * tests/Makefile.am (package.m4): New.
2353 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
2355 2001-09-20 Gary V. Vaughan <gary@gnu.org>
2357 More cleanup. After the last patch, m4_symbol holds nothing but
2358 the head of a chain of m4_token_data. So I have removed the old
2359 m4_symbol, so that m4_token_data chains are stored directly in the
2360 value cell of a hash table node. But there's more... m4_symbol
2361 was a more natural name for the symbol value cell, and now that it
2362 is gone I have renamed the former m4_token_data structure to
2363 m4_symbol. This change turned out to be a pig to get right, since
2364 the original code didn't need to modify the value cell itself,
2365 since changing the chain happened inside the m4_symbol that used
2366 to be returned -- I had to pass the address of the value cell
2367 across various function calls, incase the head value changed. I
2368 also tightened up the memory management to help me find a nasty
2369 memory corruption bug that took me all night to track down...
2371 * m4/m4private.h (struct m4_symbol): Removed.
2372 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
2374 * m4/hash.c (m4_hash_iterator_value): Return the address of the
2375 value cell. Updated all callers.
2376 * m4/symtab.c: Took advantage of the simplification in the data
2377 structures to rewrite a lot of this file more simply. There is
2378 still some room for optimisation here, but we should tackle that
2379 systematically closer to the release.
2381 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
2382 revealed. This version is ahead of CVS libtool until I get chance
2383 to flush my changes.
2384 * m4/module.c (m4_module_remove): New function that holds the core
2385 of the old m4_module_unload.
2386 (m4_module_unload): Use it.
2387 (m4_module_unload_all): When we know the modules will never be
2388 used again (i.e. on exit), free up as much module memory as
2389 possible. There are still some artifacts from resident modules
2390 living inside ltdl.c, but everything else is freed.
2391 * m4/debug.c (m4_debug_exit): Free memory allocated in
2393 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
2394 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
2395 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
2396 * m4/m4module.h: Updated prototypes.
2397 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
2398 * m4/hash.h: Updated prototypes.
2399 * src/main.c (main): Use all these new functions to clean up as
2400 much memory as possible before exit.
2402 2001-09-18 Gary V. Vaughan <gary@gnu.org>
2404 The `traced' flag needs to be attached to the definition of a
2405 symbol rather than the current symbol containing the definition.
2406 Implementing this showed up some long standing post 1.4 bugs in
2407 flag propogation which I also fixed.
2409 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
2410 (struct m4_token_data): And add it back in here.
2411 * m4/input.c (init_macro_token): Propogate the traced flag
2413 * m4/macro.c (expand_argument): Ditto.
2414 * tests/builtins.at (trace2, trace3): New tests based on Akim's
2417 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2419 * m4/m4private.h (struct m4_token_data): Simplified by removing
2420 the redundant `traced' flag, and one level of structure nesting.
2421 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
2422 * m4/input.c (init_macro_token): No need to initialise removed
2424 * m4/macro.c (expand_argument): No need to copy it either.
2425 * m4/utility.c (m4_token_data_func_traced): Or provide an access
2428 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
2429 dependant on multiple symbols with the same key, so preserving
2430 relative symbol order in each bucket during resizing is no longer
2431 required. The resize function is considerably faster as a result.
2433 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
2434 s/m4_symbol_insert/m4_symbol_define/g;
2435 s/m4_builtin_insert/m4_builtin_define/g;
2436 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
2438 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2440 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
2441 commits, the m4_lookup_symbol dispatch function is split into
2442 specialised functions that must be called directly.
2444 * m4/m4module.h (m4_symbol_lookup_t): Removed.
2445 * m4/symtab.c (m4_lookup_symbol): Removed.
2446 (m4_symbol_builtin, m4_symbol_macro): New functions.
2447 * m4/builtin.c (m4_builtin_define): Split into...
2448 (m4_builtin_pushdef, m4_builtin_insert): ...these.
2449 (m4_macro_define): Split into...
2450 (m4_macro_pushdef, m4_macro_insert): ...these.
2451 * src/main.c (main): Set command line macros from `-D' parameters
2452 using `m4_macro_define'.
2454 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2456 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
2457 this from m4_remove_table_reference_symbols().
2458 * m4/m4module.h, m4/module.c: Updated all references.
2460 2001-09-07 Akim Demaille <akim@epita.fr>
2462 * modules/stdlib.c, modules/times.c: Misc cleanups.
2464 2001-09-07 Akim Demaille <akim@epita.fr>
2466 * configure.in: We now need Autoconf 2.52e.
2467 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
2468 and `M4_SYMBOL_DELETE'.
2469 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
2470 * src/main.c (main): Adjust.
2472 2001-09-06 Gary V. Vaughan <gary@gnu.org>
2474 Fix the obstack.h problem once and for all! At configure time we
2475 can test for a system supplied obstack.h: depending on the
2476 result, we now generate system.h with an #include of the correct
2477 header. As a bonus, I've also added a --with-included-obstack,
2478 incase the user doesn't like the system obstack for some
2479 reason... and also we can test the shipped obstack on a system
2480 that has oe of its own. We also now need to be careful to add
2481 build directories to the include search path, since the generated
2482 system.h will be in the build tree.
2484 * configure.in (AC_CONFIG_FILES): Generate system.h from
2486 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
2487 include the system obstack header or the copy shipped with M4.
2488 Allow the user to override configure and force the build to use
2489 the shipped version.
2490 * m4/system-h.in: New file, template for...
2491 * m4/system.h: ...this. Now deleted.
2492 * m4/m4module.h: Include system.h before everything else.
2493 * src/freeze.c: Ditto.
2494 * m4/Makefile.am (dist-hook): Remove generated system.h.
2495 (INCLUDES): Check builddir for generated headers before checking
2497 * modules/Makefile.am (INCLUDES): Ditto.
2498 * src/Makefile.am (INCLUDES): Ditto.
2500 2001-09-05 Gary V. Vaughan <gary@gnu.org>
2502 * TODO: Remove the items that have been addressed already.
2504 2001-09-05 Akim Demaille <akim@epita.fr>
2506 * src/main.c (main): Standardize --version.
2508 2001-09-05 Akim Demaille <akim@epita.fr>
2510 * modules/format.c (format): Have a bigger `str'.
2512 2001-09-05 Akim Demaille <akim@epita.fr>
2514 Rationalize warnings, reporting the macro name as if it were a
2515 program name, and assertions.
2517 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
2519 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
2521 Use assert for internal errors.
2522 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
2524 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
2526 * tests/builtins.at (pushpop): Adjust.
2528 2001-09-05 Akim Demaille <akim@epita.fr>
2530 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
2533 2001-09-05 Akim Demaille <akim@epita.fr>
2535 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
2536 * m4/macro.c, m4/symtab.c: Adjust.
2538 2001-09-05 Akim Demaille <akim@epita.fr>
2540 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
2541 (m4_symbol_pop, m4_symbol_del): this.
2542 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
2543 (m4_symbol_popdef, m4_symbol_delete): New.
2544 (m4_lookup_symbol): Adjust.
2545 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
2547 2001-09-05 Akim Demaille <akim@epita.fr>
2549 * m4/m4module.h (m4_symbol_lookup): Rename as...
2550 (m4_symbol_lookup_t): this.
2552 2001-09-05 Akim Demaille <akim@epita.fr>
2554 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
2556 * m4/symtab.c (m4_lookup_symbol): Adjust.
2558 2001-09-03 Gary V. Vaughan <gary@gnu.org>
2560 Bootstrap will now work with Libtool 1.4.1 or higher:
2561 * bootstrap: Remove stale autom4te.cache files when
2563 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
2565 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
2566 libtool.m4 directly.
2567 Run libtoolize to refresh ltmain.sh.
2568 * config/ltmain.sh: Deleted.
2569 * acinclude.m4: Deleted.
2570 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
2572 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
2573 implementation for the cvs impaired libtool user.
2575 2001-09-03 Akim Demaille <akim@epita.fr>
2577 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
2579 Avoid using `default' in switch, as it hides useful compiler
2580 warnings when a case is forgotten.
2582 2001-09-03 Akim Demaille <akim@epita.fr>
2584 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
2585 is no such thing as `WITH_MODULES'.
2587 2001-09-03 Akim Demaille <akim@epita.fr>
2589 Improve the test suite's selfcontainedness.
2591 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
2592 (Include, Undivert): Tag the other input files.
2593 * tests/generate.awk: Catch `@comment file:'.
2594 `-I $src' is no longer needed.
2595 `next' is really like `return': the rest is skipped.
2596 Adjust to `input.m4'.
2597 (fatal): New function.
2598 * tests/foo, tests/incl.m4: Remove.
2600 2001-09-01 Gary V. Vaughan <gary@gnu.org>
2602 The shadowing mechanism and, infact, the whole symbol table
2603 implementation was creaking under the weight of the features piled
2604 on top of it. We now have a separate hash table module which will
2605 dynamically resize to keep symbol density withing good performace
2606 limits, and a new symtab module layered above it. Symbol lookups
2607 are now marginally more efficient (since the shadowed flag is no
2608 longer required) and symbol removal, such as on module unload, is
2609 considerably faster due to a reorganisation of the data structures
2612 * src/main.c (main): Don't mention `-H'.
2613 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
2616 * m4/hash.c: New generalised dynamic hash table data structure
2618 * m4/hash.h: Public interface.
2619 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
2620 (libm4_la_SOURCES): Add hash.c.
2621 * m4/symtab.c: More or less rewritten from scratch, within the
2622 bounds of the previous API.
2623 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
2624 call. Updated all callers.
2625 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
2626 declarations to reflect API changes.
2627 (M4INIT): Generate a declaration too, to avoid the warning with
2628 --enable-debug builds.
2631 * m4/utility.c (hash_table_size): Removed.
2632 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
2633 names, which are then looked up by builtin_dumpdef() as necessary.
2634 This implies a small speedup in builtin_symbols(), which discarded
2635 all of the symbol info under the old call.
2636 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
2637 shadowing is implicit in respect to the new data structures.
2638 symbol names are no longer duplicated here, they are stored in the
2639 key field of the hash table.
2640 Moved macro_args and blind_no_args...
2641 (m4_token_data): ...to here.
2642 m4/macro.c (expand_macro): Added a name argument since the symbol
2643 name is no longer copied into each struct m4_symbol. Modified all
2645 (collect_arguments): Ditto.
2646 * modules/m4.c (set_trace): Ditto.
2647 * modules/gnu.c (builtin_symbols): Updated.
2648 * src/freeze.c (produce_symbol_dump): Much improved in light of
2649 the improved symbol table layout.
2651 2001-09-01 Gary V. Vaughan <gary@gnu.org>
2653 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
2655 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
2656 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
2657 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
2658 SYMBOL_HANDLE): Ditto.
2659 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
2660 modules/gnu.c, modules/m4.c, src/freeze.c,
2661 src/main.c: Updated all references.
2663 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
2664 Automake 1.5 chokes on dynamic source file lists, Besides, it is
2665 already listed in m4_LDADD... how did that ever used to work?
2666 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
2668 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
2669 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
2671 * tests/m4: Don't call the m4 wrapper script with libtool, it
2672 works fine all by itself.
2674 2001-08-30 Gary V. Vaughan <gary@gnu.org>
2676 The experimental `changeword' feature never took off, and has
2677 no obvious advantages over `changesyntax' to compensate the
2678 enormous speed penalty it carries:
2679 * configure.in (ENABLE_CHANGEWORD): Removed.
2680 * m4/m4module.h (m4_set_word_regexp): Removed.
2681 * m4/m4private.h (m4_token_data): Removed original_text field.
2682 * m4/utility.c (m4_token_data_orig_text): Removed.
2683 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
2684 * m4/macro.c: Ditto.
2685 * src/main.c: Ditto.
2686 * modules/Makefile.am (changeword.la): Removed.

2706 In an attempt to moderate my egomania...

2709 * tests/generate.awk: When making substitutions to "@&t@", either
2710 "&" or "\&" in the substitution string argument to gsub refer back

2777 Prefer options over envvars.
2778 * src/main.c (main): First bug caught by the test suite (yeah!):

2780 invocation of --discard-comments.
2782 2001-08-27 Akim Demaille <akim@epita.fr>
2784 * tests/others.at (capitalize, changeword, comments, ddivert)

2795 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
2796 such a way that m4 does not process them.

2832 2001-08-20 Gary V. Vaughan <gary@gnu.org>
2834 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
2835 Robert Collins, building on Cygwin no longer requires Windows
2836 import and export symbol decorations.

2851 2001-08-20 Gary V. Vaughan <gary@gnu.org>
2853 Ansify the source. Previously we had a mix, where my code was
2854 in a K&R compatible style, and the preexisting code was in ANSI
2855 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
2856 and now the code base is much cleaner.

2859 VOID macro and all users.

2899 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
2900 * modules/m4.c (undivert): Disable the possibility of undiverting
2901 several files at once: it is not documented, it is inconsistent
2902 with the other macros, it can be straightforwardly mocked by
2903 several invocations, and most importantly, it prevents the
2904 possibility of other kinds of extension.
2905 Use `m4_numeric_arg'.
2907 2001-08-20 Akim Demaille <akim@epita.fr>
2909 * examples/include.m4: Typo.
2910 * tests/generate.awk: Really add it.
2911 * tests/Makefile.am: Adjust.
2912 * tests/others.at (Discard comments): It sure fails without `-c'.
2913 (include, undivert): Add -I examples/.
2915 2001-08-20 Akim Demaille <akim@epita.fr>
2917 Use sprintf, not ecft and friends since it is standard, portable,
2918 simplifies the code, and since the latter is even deprecated
2919 according to the GNU libc documentation.
2921 * modules/format.c: Drop evct support.
2923 2001-08-19 Gary V. Vaughan <gary@gnu.org>

3067 Drop Autoconf 2.13 compatibility.
3069 * configure.in (changeword): No need to undefine it, as anyway if
3070 it's defined, M4sugar moved it as m4_changeword.

3145 instead of the old module argument.

3163 (libm4_la_SOURCES): Delete list.c reference.
3164 * m4/m4private.h (m4_token_data): Add a handle field. This
3165 eliminates many of the searches to find the handle associated with
3166 various tokens that are passed between functions.
3167 (struct m4_symbol): Removed the module field. The
3168 module association does not belong with the symbol...
3169 * m4/input.c (struct m4_builtin): ...it belongs with the builtin
3170 that the module implementation code is from. Added a handle
3172 (m4_push_macro): Add a `handle' argument. Changed all callers.
3173 (init_macro_token): Set the `handle' field for the
3175 * m4/macro.c (expand_argument): Copy the new handle field during
3177 * modules/m4.c (macro_install): Use the new handle field to
3178 optimise the search for the correct builtin structure, and pass
3179 the handle details to m4_builtin_define.
3181 2001-08-15 Akim Demaille <akim@epita.fr>
3183 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Be sure `m4/' exists
3184 when creating `m4/obstack.h'.
3185 * tests/Makefile.am (TESTS_ENVIRONMENT): Pass top_srcdir and
3187 * tests/defs: Make them absolute.
3188 (CDPATH) Neutralize.
3189 * tests/gethem: Use them.
3191 2001-08-14 Gary V. Vaughan <gary@gnu.org>
3193 * config/ltmain.sh: Doh! Import again for a quoting fix that
3194 prevented any regression test from passing.
3196 * m4/m4module.h (obstack.h): Choose between installed version
3197 and shipped version based on configure tests.
3198 * src/freeze.c (obstack.h): Ditto.
3200 * acconfig.h: Removed. No longer required.
3202 * bootstrap: Rewritten to play nicely with Autoconf 2.5x.
3203 * configure.in (MY_NAME, MY_VERSION): Define these once, and feed
3204 them to AC_INIT and AM_INIT_AUTOMAKE.
3205 * Makefile.am (AUTOMAKE_OPTIONS): Remove `gnits' which would
3206 disallow MY_NAME and MY_VERSION arguments to AM_INIT_AUTOMAKE.
3207 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Don't choke on
3208 shell variable m4_cv_func_obstack_h.
3209 * tests/defs (M4): Be more careful about relative path to libtool
3210 script and m4 binary by using $srcdir.
3212 * src/main.c (main): Use lt_dlinsertsearchdir to prepend -M
3213 optargs to the existing libltdl search path.
3214 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.
3215 * m4/ltdl.c: Updated.
3217 * config/ltmain.sh: Ditto.
3219 2001-08-11 Gary V. Vaughan <gary@gnu.org>
3221 * src/main.c (main): Add `-b' (for `batch') mode switch to force
3222 interactive mode off.
3224 2001-08-10 Akim Demaille <akim@epita.fr>
3226 * configure.in: Require Autoconf 2.52.
3227 (AC_ARG_PROGRAM): Remove, handled by Automake.
3228 (m4_getopt): Rename as...
3229 (m4_getopt_h): this.
3230 Allow the tokens `m4_cv_*', `m4_top_srcdir', and `m4_getopt_h'.
3231 Undefine `changeword' only if defined.
3232 * config/gnu-obstack.m4: Require Autoconf 2.52.
3233 (M4_AC_FUNC_OBSTACK): Rename `m4_obstack' and `m4_obstack_h'.
3236 2001-08-09 Yuji Minejima <ggb01164@nifty.ne.jp>
3238 * doc/m4.texinfo: Fix some typos, and apply some small
3241 2001-08-09 Andreas Schwab <schwab@suse.de>
3243 * src/main.c (main): Fix improper uses of error (missing format
3246 2001-08-07 Akim Demaille <akim@epita.fr>
3248 Improve `make distcheck'.
3250 * configure.in: Be sure to be able to run `mkconfig.sh' when src
3252 * Makefile.am (dist-hook): Remove, as it is no longer needed.
3253 * doc/m4.texinfo (Include): Add missing blank.
3254 * m4/Makefile.am (EXTRA_DIST): Distribute gnu-obstack.h and
3257 2001-08-07 Akim Demaille <akim@epita.fr>
3259 * m4/evalparse.c: A better introductory comment.
3260 * m4/m4module.h (M4_DEBUG_PRINT2): s/M4_debug/m4_debug/.
3261 * m4/macro.c: Adjust old comments.
3262 * modules/README: Typo.
3264 2001-08-07 Akim Demaille <akim@epita.fr>

3271 * configure.in, Makefile.am: Adjust.
3273 2001-04-08 Roderick Koehle <Roderick.Koehle@infineon.com>
3275 * modules/format.c (format): Formatting for %f was not
3276 interpreting the position of the decimal point correctly for
3279 2000-12-01 Gary V. Vaughan <gary@gnu.org>
3281 * TODO: Removed m4exit bug.
3282 * modules/load.c (m4_resident_module): Make this module resident.
3283 * module/m4.c (m4_resident_module): Ditto.
3284 * m4/modules.c (m4_module_load): Use new ltdl resident modules
3285 feature to mark modules as resident if they export
3286 `m4_resident_module' as TRUE.
3287 (m4_module_unload): Do not remove resident modules, and take care
3288 with symbol insertion and deletion with resident modules.
3289 * m4/ltdl.c, m4/ltdl.h: Update to latest unreleased versions to
3290 use resident modules feature.
3292 2000-11-30 Gary V. Vaughan <gary@gnu.org>
3294 * TODO: Updated. Removed some cruft that has since been fixed
3295 or implemented. Added some more entries.
3298 * modules/README: Updated.
3299 * doc/m4.texinfo: Updated.
3301 * modules/gnu.c (builtin_functions): Make indir orthogonal to
3302 builtin, in that each is recognised as a macro only with parameters
3303 (builtin_indir): Passing 0 arguments is now an error, as with
3306 * src/main.c (usage): Added missing description of `-c' option.
3308 2000-11-29 Gary V. Vaughan <gary@gnu.org>
3310 Consolidate the myriad of dispersed test scripts into the
3311 tests subdirectory. I think I now have all the file where I
3312 want them, so there shouldn't be anymore upheaval =)O|

3332 of the tests removed below.
3333 * examples/Makefile.am, modules/Makefile.am: Updated to

3351 modules/unfrozen.m4, modules/unload.test: Removed.
3353 Move the implementation of GMP support for the mpeval() builtin
3354 into a loadable module that depends on libgmp. mpeval() and
3355 eval() share a common parser, now in m4/evalparser.c; the code
3356 in m4/numb.c and m4/numb.h is now physically split between
3357 m4/eval.c (the eval() backend) and modules/mpeval.c (the
3358 mpeval() backend), rather than being differentiated by cpp
3359 macros and multiple inclusion. The mpeval module is always
3360 built but will generate an diagnostic if it is used from an
3361 installation that didn't link in the gmp library.
3362 * modules/Makefile.am: build and install the new mpeval module.
3363 * modules/mpeval.c: Now contains the former parts of m4/numb.c
3364 and m4/numb.h that are required for gmp support in mpeval().
3365 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
3366 * m4/evalmp.c: Removed.
3367 * m4/m4module.h: Removed conditional prototype for
3369 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
3370 and m4/numb.h that do not rely on gmp.
3371 * m4/evalparse.c: New file, contains the shared parts of the
3372 eval() and evalmp() parser implementations, and is no longer
3373 unencumbered by cpp magic to uncover the right parts.
3374 * m4/numb.h: Removed. It's former contents are split between
3375 m4/eval.c and modules/mpeval.c.
3378 * tests/other-tests/changeword.test: New test. Rudimentary
3379 testing of changeword builtin runs only if --wnable-changeword
3380 was used at configure time.
3381 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
3382 alternation correctly. Split into two expressions to compensate.
3383 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
3384 * modules/Makefile.am: Build changeword module.
3385 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
3386 only when --enable-changeword was passed to configure.
3387 (builtin_changeword): If --enable-changeword was not used, then
3388 report that changeword() builtin has no support in m4 binary.
3390 2000-11-28 Gary V. Vaughan <gary@gnu.org>
3392 * src/main.c (main): Fixed a particularly nasty bug is
3393 user_search_path setting -- the -M flag processing must be
3394 extremely careful with search path ordering, or else the default
3395 installed module directory (possibly containing modules from a
3396 previous release) is placed earlier in the search path than any -M
3397 arguments (which are relied upon to load uninstalled modules with
3398 most of the tests in the regresion suite).
3400 * modules/load.c (builtin_load): Nasty hack to prevent adding
3401 symbols to symtab again if a module is loaded more than once.
3402 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
3404 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
3405 possible NULL pointer dereference.
3407 * m4/module.c (m4_module_find_by_modname): Renamed from
3408 m4_module_modname_find. Fixed all references.
3409 (m4_module_find_by_builtin): New function.
3411 * modules/modfreeze.test: load the `load' module with each
3413 * src/freeze.c (produce_frozen_state): Simplified in light of
3414 module field in m4_symbol. Allow a third argument for text macros
3415 to name the originating module.
3416 (reload_frozen_state): ditto.
3417 * m4/m4module.h: Fixup prototypes.
3418 * m4/builtin.h (m4_builtin_define): Add a module argument so
3419 that symbols can be registered against the defining module.
3420 (m4_macro_define): ditto.
3421 * m4/m4private.h (m4_symbol): Make the module field const to save
3422 on casting in the rest of the code.
3423 (SYMBOL_MODULE): New macro.
3425 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
3426 symbol reference maintenance bugs when removing a symbol from the
3429 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
3431 2000-11-27 Gary V. Vaughan <gary@gnu.org>
3433 * configure.in (m4_cv_func_obstack): A better check for whether
3434 libc has an obstack implementation.
3435 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
3437 * configure.in (--with-modules): Changed semantics. This
3438 option is now used to list modules to be preopened.
3439 * src/m4.h: #include "ltdl.h" unconditionally.
3440 * src/main.c: Removed all dependencies on WITH_MODULES.
3441 * src/freeze.c: ditto.
3442 * modules/Makefile.am: ditto.
3443 * m4/m4.c (builtin_m4exit): ditto.
3444 * modules/modpath1.test: ditto.
3445 * modules/modpath2.test: ditto.
3446 * modules/modpath3.test: ditto.
3447 * modules/modpath4.test: ditto.
3448 * modules/modtest.test: ditto.
3449 * modules/shadow.test: ditto.
3450 * modules/unload.test: ditto.
3452 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
3453 comes up on demand in LTLIBOBJS now.
3454 * configure.in (getopt_long): Creating and relying on a link for
3455 getopt.h on hosts with no getopt_long() of thier own works
3456 correctly now. This is necessary so that callers of getopt_long()
3457 can simply `#include <getopt.h>': the naive way of doing this
3458 would end up using our own getopt.h and the installed
3459 getopt_long(), which is asking for trouble!
3460 (obstack_init): A similar argument applies to obstack.h and
3463 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
3464 On Solaris-2.5 (at least) the native dlopen implementation
3465 gets confused about m4.o when looking for module "m4". This
3466 version always looks for .la an .$lib_ext suffixed names first
3467 to work around the problem. Sigh.
3469 * po/POTFILES.in: Take account of these file movements.
3470 * src/Makefile.am (m4_SOURCES): removed eval.c.
3471 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
3472 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
3473 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
3474 * modules/m4.c (builtin_eval): Use m4_evaluate().
3475 * m4/eval.c: Moved here from src/eval.c to facilitate
3476 implementation of eval() builtin as part of the `m4' loadable
3478 (m4_evaluate): renamed from evaluate for namespace cleanliness.
3479 * m4/numb.c: Moved here from src/numb.c, since it is #included
3480 into eval.c at compile time.
3481 * m4/m4module.h (m4_evaluate): Added prototype.
3482 * src/m4.h (evaluate): Removed prototype.
3484 2000-11-25 Gary V. Vaughan <gary@gnu.org>
3486 * modules/perl.c (builtin_perleval): Use PL_na for
3487 compatibility with perl-5.6.
3489 * src/main.c (main): It is now safe to
3490 ``m4_module_install("m4")'', without tripping over the m4
3492 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
3493 versions having fixed the insidious module search order bug.
3495 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
3496 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
3498 * configure.in: Figure out whether to use the installed
3499 getopt.h or the supplied one.
3500 * src/Makefile.am: ditto.
3502 * po/POTFILES.in: List files in their new positions.
3504 * config/ltmain.sh: This needs to be checked in to match the
3505 libtool macros copied to acinclude.m4 (until a released
3506 libtool copes with m4's needs).
3507 * bootstrap: Run gettextize.
3509 2000-11-24 Gary V. Vaughan <gary@gnu.org>
3511 * AUTHORS: Added my details.
3514 * bootstrap: temporary update until released libtool catches up.
3516 * All files: Use new GNU GPL copyright blurb with current contact
3519 * configure.in (LTLIBOBJS): Use canonical code for calculation of
3522 * config: renamed acm4 directory to config to be more like
3523 other autoconfiscated packages.
3525 * configure.in (M4_AC_CHECK_DEBUGGING): Use it.
3526 * config/debug.m4: New file implementing configure macros to add
3527 suitable debug flags to the compiler invocation.
3529 * modules/load.c: New file implementing the ``load'' and
3530 ``unload'' builtins.
3531 * tests/get-them: Set the module search directory to the modules
3532 build directory in generated tests.

3544 builtin as a loadable module.
3545 * modules/mpeval.c: New file implementing the ``mpeval'' builtin
3546 as a loadable module.
3548 * src/main.c (main): Load the gnu module if m4 was started
3549 normally -- i.e. without the -G option.
3550 * modules/gnu.c: New file implementing a new loadable module wuth
3551 definitions for all the gnu extension builtins.
3552 * modules/format.c: Moved here from src/format.c. Now included
3555 * src/main.c (main): Load the traditional module if m4 was
3556 started in `no_gnu_extensions' mode.
3557 * modules/traditional.c: New file implementing the ``unix'' macro,
3558 required when m4 is executed in traditional mode, as a loadable
3561 * src/main.c: Renamed from m4.c to avoid confusion with
3563 (main): Always load the m4 module.
3564 * modules/m4.c: New file implementing a new loadable module with
3565 definitions for all m4 builtins that are not gnu extensions.
3567 * m4/Makefile.am: Adjusted to take new files below into account.
3568 * m4/m4module.h: Prototypes for exported functions and types moved
3569 to this directory from the src directory.
3570 * m4/m4private.h: Moved here from src/m4private.h to facilitate
3571 the migration of all builtin implementations to loadable modules.
3572 * m4/macro.c: Moved this file here from the src directory,
3573 renaming all exported symbols to use the prefix ``m4_''.
3574 * m4/builtin.c: ditto.
3575 * m4/module.c: ditto.
3576 * m4/symtab.c: ditto.
3577 * m4/debug.c: ditto.
3578 * m4/input.c: ditto.
3579 * m4/output.c: ditto.
3581 * m4/ltdl.h, m4/ltdl.c: ditto.
3582 * m4/utility.c: Odd functions moved here from files in the src
3583 directory to facilitate builtin migration.
3585 2000-08-12 Gary V. Vaughan <gary@gnu.org>
3587 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
3588 error message, to make translators' jobs a little easier.
3589 (builtin_builtin): ditto.
3590 (builtin_traceon): ditto.
3591 (builtin_traceoff): ditto.
3592 Reported by Akim Demaille <akim@epita.fr>
3594 * m4/Makefile.am (pkgincdir): Deleted. Use automake's built in
3595 pkgincludedir instead.
3597 * m4/m4module.h (rquote): Renamed with a prefix of `m4_' since
3598 it is exported globally. Fixed all references.

3614 (AC_OUTPUT): touch stamp-h.in, not stamp-h.
3616 * doc/m4.texinfo: Fixed to work with --html option of makeinfo.
3617 Removed `Prev', `Next' and `Up' fields of all @nodes now that
3618 makeinfo calculates them for us, and to make any future
3619 reorganisation easier.
3620 (Frozen files): Document format version 2.
3621 `V' now takes argument `2'.
3622 `F' can take a single argument if symbol and builtin names
3623 are the same, or 3 arguments if the builtin is from a module.
3624 New `S' specification for saving syntax table contents.
3625 New `M' specification for saving loaded module names.
3626 * src/freeze.c: Implement them.
3627 * src/input.c (syntax_code): For interpreting frozen syntax
3630 * examples/Makefile.am: Add the contents of the WWW directory to
3632 * examples/WWW/Makefile: ditto,
3633 (%.htm): Compares file contents (not just sizes) to determine
3634 whether a change has occured.
3635 * examples/WWW/_header.htm: Bumped version number.
3636 * examples/WWW: Regenerated content.
3638 * m4/Makefile.am (AUTOMAKE_OPTIONS): Support for non-ANSI
3639 compilers comes much easier without ansi2knr.
3640 * src/Makefile.am (AUTOMAKE_OPTIONS): ditto.
3642 * m4/list.c: New generic list container type.
3643 * m4/list.h: Interface to new container type.
3644 * m4/Makefile.am (pkginc_HEADERS): Install list.h.
3645 (libm4_la_SOURCES): compile and link list.c.
3646 * src/builtin.c (builtin_tables): Use list container.
3647 * src/module.c (symtab): ditto.
3648 * src/symtab.c (symtab): ditto.
3650 * m4/system.h: New file for common preprocessor definitions.

3839 src dir and immediately after libm4 is built for confidence that
3840 it doesn't rely on the src directory.
3841 (SUBDIRS): Moved doc dir to the end since helptoman.pl and
3842 makeinfo stop the build on cygwin (because they don't work).
3844 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
3846 * m4/m4private.h: ...is not a public header, so moved to src.

3890 From Akim Demaille <akim@epita.fr>
3892 2000-01-17 Gary V. Vaughan <gary@gnu.org>
3894 * src/ltdl.c: Use access() to abort doomed module load attempts
3895 if module file does not exist.
3897 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
3898 getopt1.o will already be used if appropriate, so I moved getopt.c
3899 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
3901 * modules/modpath1.test: Use correct filename in header line.
3902 * modules/modpath2.test: ditto.
3903 * modules/modpath3.test: ditto.
3904 * modules/modpath4.test: ditto.
3906 Without these changes lt_dlopen("test") attempts to
3907 LoadLibrary("/bin/test") on Windows, which although harmless
3908 generates a spurious error message which spoils most of the tests:
3909 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
3910 (TESTS): s/test.test /modtest.test /
3911 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /

3929 * modules/Makefile.am (TESTS): New tests for the module system.
3931 * modules/*.test: New files.
3933 * src/m4.c (main): Added call to module_init().
3934 Treats -M and -m as the arguments -D -U and -t, ie deferred.
3936 * src/m4.h: Added declaration of module_init().
3938 * src/module.c (module_init): No longer static
3940 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
3941 Added to shut up automake about non standard libtool library

3959 * lib/COPYING.LIB: updated to version 2.1.
3961 * lib/m4module.h: restructure the M4_SCOPE code to work when
3962 creating a dll which links with libm4.la and both DLL_EXPORT
3963 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
3966 2000-01-11 Gary V. Vaughan <gary@gnu.org>
3968 Merged the following changes from my tree:
3970 1999-06-15 Gary V. Vaughan <gary@gnu.org>
3972 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
3973 ported to compile shared libs.
3975 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
3976 use `__declspec(dllimport)' when linking libm4.la on win32.
3977 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
3979 * configure.in (M4OBJS): Discover whether we need the shipped
3980 implementation of getopt_long.
3981 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
3982 main binary here, as opposed to the module library in lib/libm4.la.
3984 1999-06-14 Gary V. Vaughan <gary@gnu.org>
3986 * modules/README: Updated to describe the improved libltdl based
3988 * README (cygwin): Added some compilation notes for building m4
3989 correctly under cygwin.
3990 * TODO: Cleaned out the entries for the module system since they
3991 are now implemented.
3993 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
3994 all instances of __P with M4_PARAMS.
3996 * lib/getdate.h: removed unreferenced file.
3998 * lib/m4private.h: New file to define the private interface to the
3999 token_data struct, which must be shared between m4module.c, and
4000 builtin.c but not exported to modules built from the installed
4001 m4module.h since it's size changes depending on compile time
4004 * src/m4.h: Lots of stuff moved to lib/m4module.h.
4006 * lib/m4module.h: New file to define the interface available when
4007 compiling m4 modules.
4008 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
4009 necessary for module compilation into this new file.
4011 * lib/Makefile.am (include_HEADERS): install headers (renamed to
4012 avoid nameclash with other system headers) necessary for compiling
4014 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
4015 so that modules can include the (renamed) installed headers and
4016 be guaranteed a matching implementation.
4017 * lib/m4error.h: renamed from error.h.
4018 * lib/m4obstack.h: renamed from obstack.h.
4019 * lib/m4regex.h: renamed from regex.h.
4020 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
4021 implementation, simply include the shipped version
4022 unconditionally, otherwise it is hard for a module to know
4023 whether the m4obstack.h header it is using matches the
4024 implementation it ends up linking against.
4025 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
4028 1999-05-18 Gary V. Vaughan <gary@gnu.org>
4030 * examples/misc.test: Don't run this test on machines which don't
4031 have a root user in /etc/passwd (e.g. cygwin).
4033 * tests/get-them (/^@example$/): Error messages might have a
4034 ``.exe'' suffix to the program name, or else use the libtool
4035 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
4036 of these cases are now catered for when comparing error messages
4038 * tests/other-tests/*.test: ditto.
4039 * examples/*.test: ditto.
4041 * tests/defs (M4): use libtool execute mode.
4042 * examples/defs (M4): ditto.
4044 * tests/get-them (END): explicitly close any open file.
4045 (printthem): In a regular expression, '{' is the start of a repeat
4046 count! Use `[{]' for a literal open brace.
4047 (/^@node /): Don't use substr on a string shorter than the trim
4050 1999-05-17 Gary V. Vaughan <gary@gnu.org>
4052 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
4054 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
4056 2000-01-10 Andreas Schwab <schwab@suse.de>
4058 * tests/other-tests/gmp.test: Find config.sh in build directory.
4060 * configure.in: Find tests/mkconfig.sh in $srcdir.

4068 2000-01-10 Rene' Seindal <rene@seindal.dk>
4072 * TODO, NEWS: Cleaned up and updated.
4074 * src/m4.c (main): New variable exit_status for exit status in
4075 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
4076 file cannot be read instead of EXIT_SUCCESS.
4078 * src/builtin.c (m4_indir): Changed error message to help
4079 translators (from Akim Demaille <demaille@inf.enst.fr>).
4081 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
4084 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
4087 * src/input.c (match_input): Reordering of code, to avoid multiple
4088 calls to push_string_init() from obstack_grow(), which can happen
4089 with some compilers (found and fixed by James Bonfield
4090 <jkb@mrc-lmb.cam.ac.uk>).
4092 * src/stackovf.c: Added prototypes for ultrix.
4093 (setup_stackovf_trap): Added __P to cast.
4094 (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>)
4096 2000-01-09 Rene' Seindal <rene@seindal.dk>
4098 * doc/m4.texinfo (Changequote): Added comment about changing
4099 quotes when the old quote is a part of the new.
4101 * src/builtin.c (expand_ranges): Added break after trailing dash.
4102 This caused misbehavious on some systems (found and fixed by Akim
4103 Demaille <demaille@inf.enst.fr>).
4105 * AUTHORS: Thomas Tanner included
4107 * acconfig.h: Added entry for ss_sp (see below).
4109 * configure.in (use_stackovf): Added check for stack_t with member
4110 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert

4123 * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal.
4125 * src/module.c: reindented.
4126 (module_load): return if this is a repeated load of same module.
4127 (module_init): slight change of logic to avoid repeated
4128 initialisation debug messages.
4130 * Makefile.am (DIST_SUBDIRS): Added to ensure modules/ is included
4131 in the distribution.

4143 1999-11-09 Paul Eggert <eggert@twinsun.com>
4145 * src/m4.h (voidstar): Define to void * if __STDC__ is defined

4147 (bcopy): Remove macro; no longer needed with new obstack.h.
4149 * src/output.c (freeze_diversions): Don't assume that a
4150 diversion size can fit in `int'. Check for diversion file

4175 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
4176 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision

4185 into running executable before reading the source.
4186 (--module-directory): prepend a directory to the module search
4188 (module_init()): Do this the first time we load a module instead;
4189 if the module subsystem is broken normal m4 scripts can still run.

4205 * src/Makefile.am (MAINTAINERCLEANFILES): ditto.
4206 * tests/Makefile.am (MAINTAINERCLEANFILES): ditto.
4208 * acinclude.m4: removed. `aclocal -I acm4' handles this much
4210 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
4211 * acm4/gettext.m4: removed. It causes a multiple definition vs.
4212 the installed gettext.m4 file when running aclocal.
4214 1999-03-25 Gary V. Vaughan <gary@gnu.org>
4216 * configure.in (AM_INIT_AUTOMAKE): bumped version number to

4222 lib prefix on a module" feature.
4223 (LDFLAGS): Added `-module -avoid-version' flags to build
4224 versionless module libraries.

4230 * src/m4.h (module_init): removed. No longer relevant.
4231 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on
4232 exported symbols for compatibility with dlpreopening.
4233 * modules/test.c (m4_macro_table, m4_init_module,
4234 m4_finish_module): ditto.
4235 * modules/time.c (m4_macro_table): ditto.
4237 * bootstrap: New file. Runs all the autoutils in the right order
4238 after a fresh checkout, or a make maintainer-clean.

4257 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
4259 * src/module.c (module_try_load): Don't try to be clever and
4260 overwrite argument string. Instead allocate all constructed
4261 strings locally, since they can have arbitrary lengths. Make
4262 arguments pointers to const.
4263 (module_search): Simplify due to above change.
4265 1998-11-29 Rene' Seindal <rene@seindal.dk>

4291 1998-11-28 Rene' Seindal <rene@seindal.dk>
4293 * src/m4.c (main): New option --import-environment (no single
4296 * When configured with --with-gmp both the normal (fast) eval()
4297 and the gmp aware mpeval() are defined. To restore previous
4298 bahaviour use "define(`eval', defn(`mpeval'))".
4300 * tests/other-tests/gmp.m4: Changed to use mpeval().
4302 * src/evalmp.c: New file for compiling eval.c as gmp aware.
4303 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
4305 * src/eval.c: Now includes "numb.c" directly. Everything in this
4306 file must by static, except evaluate(), which is changed to
4307 mp_evaluate() if USE_GMP in force.
4309 * src/numb.c: Changed to be included by eval.c instead of being
4310 compiled separately. Everything is declared static.
4312 * src/numb.h: Removed declarations of functions, as numb.c is now

4325 * src/m4.c (main): m4 --version also shows which options were used
4326 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
4328 1998-11-27 Rene' Seindal <rene@seindal.dk>
4330 * Error messages now always print program name before input file
4331 name as specified by GNU coding standards. Reported by Akim
4332 Demaille <demaille@inf.enst.fr>.
4334 * doc/m4.texinfo (Include): Change due to changed error message
4338 * tests/get-them: Minor change to sed script due to changed error
4341 * src/m4.c (print_program_name): New func used to print program

4343 error_print_progname handler.
4344 (reference_error): Removed.
4345 (main): Assigns error_print_progname.
4347 * src/m4.h (M4ERROR): Removed reference_error ().

4351 * Updated to libtool 1.2b.
4353 * src/builtin.c (install_builtin_table): Added braces to avoid
4354 warning of ambiguous 'else'.
4356 * src/module.c: Inserted search path code from path.c modified to
4358 (module_init): Configured default path used only if M4MODPATH is
4360 (module_try_load): Now reads libMODULE.la as generated by libtool
4361 for actual module name.
4362 (module_load): Gives better error messages on failure.

4368 functions of more generic search path handling.
4370 1998-11-24 Rene' Seindal <rene@seindal.dk>
4372 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
4373 included gettext, as <libintl.h> might not be found
4374 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
4376 1998-11-22 Rene' Seindal <rene@seindal.dk>
4378 * src/output.c (insert_diversion): Fixed bug that might cause m4
4379 to read from standard output! Triggered by input
4380 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
4381 so now 'undivert(0)' does nothing.
4383 1998-11-18 Rene' Seindal <rene@seindal.dk>
4387 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
4388 could be changed when compiling a illegal regexp, causing later
4389 use of the regexp to dump core.
4391 * src/module.c (module_load): Changed error message to conform to
4394 * src/m4.c (usage): Added message about reporting bugs.

4407 * modules/Makefile.am: Changed completely to compile modules using
4408 libtool. The modules are compiled as shared libraries, and are
4409 renamed when installed.
4411 * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
4412 USE_SHL_LOAD to HAVE_SHL_LOAD
4414 * src/builtin.c (shipout_string): Now tests for a NULL string.

4430 getpwuid, hostname, rand, srand, getenv, setenv, unsetenv, uname.
4432 * src/builtin.c (shipout_string): New convenience function for
4433 builtins and modules.
4435 * src/module.c (module_load): Tentative support for

4444 These two are now initialised by autoconf macros.
4446 * src/path.c (module_env_init): MODULE_PATH is always on the
4449 * src/Makefile.am: Now generated pathconf.h which defined the
4450 default MODULE_PATH.
4452 * configure.in (pkglibexecdir): Added defintion of pkglibexecdir,
4453 where modules are installed.
4455 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
4456 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
4457 build and install automatically, and it is prepared for other
4458 interfacec than dlopen().
4460 * src/builtin.c (predefined_tab): Added __m4_version__ for the
4461 current version of GNU m4. It is a GNU extension.
4463 1998-11-14 Rene' Seindal <rene@seindal.dk>

4493 * tests/Makefile.am (GENERATED_TESTS): Renamed gentest to
4496 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): Added manually
4497 maintained tests in tests/other-tests. These currently tests for
4498 8-bit transparency, multiple precision arithmetic and sync-line
4499 output. Test for stackoverflow detection does not work.

4541 1998-10-07 René Seindal <rene@seindal.dk>
4545 * tests/Makefile.am (GENERATED_TESTS): Changed .m4 extension to
4546 .test, as the files are no longer just m4 input.
4548 * tests/get-them (FILE): Changed .m4 extension to .test.
4550 * src/m4.h (token_type): New token type TOKEN_SPACE introduced.
4551 Otherwise quoted strings with leading whitespace first in a macro

4555 (expand_argument): Do.
4557 * src/input.c (next_token): SPACE and NUM/OTHER characters are only
4558 grouped together iff both quote and comment strings are single
4559 character. Otherwise they might include a comment/quote leader.
4560 (next_token): Returns new token type TOKEN_SPACE.
4562 * src/builtin.c (push_builtin_table): New function to push a
4563 builtin_table on the stack without installing its contents.
4564 (find_builtin_by_name): Added call to push_builtin_table() if
4565 reading frozen files. Otherwise the builtins named in the frozen
4566 files could not be found.

4569 1998-10-04 René Seindal <rene@seindal.dk>
4573 * configure.in (ALL_LINGUAS): Added Polish pl.po
4575 1998-10-03 René Seindal <rene@seindal.dk>
4577 * Many files: Incorporated changes to implement dynamic modules.

4585 * src/builtin.h: New file, declares some functions from builtin.c
4586 that are of use for other modules (shipout_int, numeric_arg,
4587 skip_space, bad_argc), and the macros ARG() and DECLARE().
4589 * src/builtin.c (install_builtin_table): New function. Each
4590 module brings in a builtin_table, which is pushed on a stack.
4591 (struct builtin_table): New struct for list of builtin_tables.
4592 (m4_loadmodule): New function to implement builtin "loadmodule".
4593 (shipout_int): No longer static, to be used by modules.

4601 * src/path.c: Reorganised to allow for two search paths, one for
4602 include files and one for modules.
4604 * src/m4.h: Added declarations for new functions in module.c and
4607 * src/m4.c (main): Added call to module_init().
4609 * modules: New directory with a few demo modules.
4611 * Makefile.am (EXTRA_DIST): Added modules/* since modules/ is not
4614 * configure.in: Added modules/Makefile to AC_OUTPUT.
4616 * configure.in: Added code to implement --with-modules. Tests for
4619 * acconfig.h: Added WITH_MODULES
4621 1998-10-02 René Seindal <rene@seindal.dk>
4623 * examples/Makefile.am (pkgdata_DATA): Removed special target for
4624 check and variables TESTS. These tests are now run from the
4627 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
4628 directory. The files stay there but the tests are run from the
4631 * tests/Makefile.am (EXTRA_DIST): Added run-test.
4633 * tests/run-test: New file. Run a test manually
4635 * tests/Makefile.am, tests/get_them: Moved automatically generated
4636 tests (from the manual) to sub directory tests/gentest/. The
4637 tests/ directory had gotten a bit messy.
4639 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4641 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\
4642 wrap}.test: Added a few testcases.
4644 1998-08-21 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4648 * lib/Makefile.am (noinst_HEADERS): regex.h added
4650 * configure.in (jm_WITH_REGEX, jm_PREREQ_ERROR):
4651 acm4/{error,regex}.m4 (from fileutils-3.16u.tar.gz).
4653 * acm4/Makefile.am: created providing rules to create
4654 $(top_srcdir)/acinclude.m4 to be used by aclocal.
4656 * tests/defs (LANGUAGE, LC_ALL, LANG): force them to be
4657 `C'. Reported by Ulrich Drepper.
4659 * Makefile.am (SUBDIRS): Removed checks directory
4660 * configure.in (AC_OUTPUT): Removed checks/Makefile
4662 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
4663 the space when m4.texinfo is edited and whitespace.el is active.
4664 (Defn,example): idem.
4666 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4668 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
4669 ../COPYING. ../Makefile is a file which is certainly present when
4670 test is executed in testSubDir. One can't be sure that the COPYING
4671 file is in .. or ../.. in all situations, the ../Makefile is
4674 * doc/m4.texinfo (Include): adjusted expected test output
4675 according to new tests, i.e. the input will always come from the
4676 file `in' created by the test.
4678 * tests/Makefile.am: Added three lines at the top to get
4679 esyscmd.1.test working.
4681 * tests/get-them: modified to generate clearer tests who will need
4682 less maintenance when new test examples are created in
4683 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
4684 need the generic file `defs') shell scripts creating `in', `ok',
4685 `out' and when apropriate `okerr' and `err' in the directory
4686 `testSubDir' when executed. The compare of `ok' and `out'
4687 (and of `okerr' and `err') will be the exit status of the test.
4688 `out' must match `ok' (and `okerr' must match `err') for the test
4691 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
4692 the tests generated by tests/get-them getting it input normally
4693 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
4694 (dot) before the numeric part) is reserved for all other (hand
4695 written) tests. The `+' means one or more times.
4697 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4699 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
4700 supported short man page to refer to info documentation
4701 * helptoman.pl: added
4702 * configure.in: AC_PATH_PROG(PERL,perl)
4703 * Makefile.am (SUBDIRS): doc after src
4705 * libitized with libit 0.5 from
4706 ftp://ftp.iro.umontreal.ca/pub/contrib/pinard/maintenance/libit.

4726 * src/builtin.c (m4_changesyntax): Added builtin macro
4727 "changesyntax" to modify the syntax table.
4729 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax
4730 table. All categories are assigned a syntax code and tokens are
4731 read according to this table.
4733 1998-08-09 René Seindal <rene@seindal.dk>
4735 * src/numb.{c,h}: New files, implements multiple precision eval
4736 using GNU gmp. Originally submitted by John Gerard Makecki
4737 (johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.
4739 * doc/m4.texinfo (Eval): Added documentation for multiple
4740 precision arithmetic library support.
4742 * src/m4.{c,h}, src/eval.c, src/builtin.c, configure.in: Changes
4743 to accommodate multiple precision eval.
4745 1998-08-07 René Seindal <rene@seindal.dk>
4747 * src/input.c (MATCH, match_input), src/m4.h: changed definition
4748 of comment and quote strings to `unsigned int' to allow eight bit
4749 chars (reported by andrewb@zip.com.au (Andrew Bettison)).
4751 * src/builtin.c, doc/m4.texinfo: Builtin `syncoutput' added by
4752 patch from Mike Howard <mike@clove.com>
4754 1998-08-06 René Seindal <rene@seindal.dk>
4756 * gettext.m4: corrected AM_WITH_NLS to handle use of installed
4759 1998-08-03 René Seindal <rene@seindal.dk>
4763 * src/m4.h: Added ifdef ENABLE_NLS around include of <libintl.h>
4764 and _ macro. M4 now builds with --disable-nls.
4766 * src/m4.c (main): reintroduced textdomain(PACKAGE) to get gettext
4767 to look for right message catalogs. Call indef'ed by ENABLE_NLS.
4769 * configure.in (ALL_LINGUAS): Added complete list of translations:
4770 de fr it ja nl ru sv.

4990 1994-09-13 François Pinard <pinard@iro.umontreal.ca>
4994 * Makefile.in: Group all *clean-recursive goals in one, using sed
4995 to remove `-recursive' while calling make recursively. Also, use

5006 * configure.in: Use date instead of touch for stamp-h.
5007 * Makefile.in (stamp-h.in): Idem.
5009 * Makefile.in (distclean, realclean): Force serial execution of

5061 * src/m4.c: Have -P set prefix_all_buitins variable instead of
5062 calling a function by that name. Declare the variable.
5063 * src/m4.h: Adjust declaration for prefix_all_buitins.
5064 * src/builtin.c (builtin_init): Merge in functionality from
5065 previous prefix_all_buitins function, while making entries in the
5066 symbol table, but not modifying the builtin description itself.
5068 * src/freeze.c (reload_frozen_state): Add a useless `break;',
5069 because *many* compilers do not accept an empty `default:'.
5070 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
5071 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.

5131 frozen. Do not call builtin_init when reloading frozen state.
5133 Speed up diversion processing:

5156 * Makefile.in: Compile it, distribute it.
5157 * m4.c: Recognize, document and process --freeze-state (-F) and

5262 this way, a change in lib will be detected and processed.
5264 * builtin.c (numeric_arg): Use strtol and verify the conversion,
5265 instead of using sscanf which stops as soon as there is a
5266 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
5267 and divert(1xyzzy) were all accepted without any warning or error
5269 * m4.h: Declare strtol as long if not including stdlib.h.
5270 * configure.in: Check for limits.h, and replace strtol if missing.
5271 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.

5287 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
5288 handlers), and a default error message if the fault address is not
5289 available (when neither siginfo.h nor BSD sigcontext are supported).
5290 * configure.in: Changes for stackovf.h: Check for sigcontext,
5291 sigaction, sigstack, and define rlim_t as int if necessary.
5292 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.

5307 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
5308 because siginfo.h is unrelated to standard headers, and siginfo.h
5309 is already checked for.
5310 Reported by Joseph E. Sacco.
5312 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
5314 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
5317 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
5319 * builtin.c (substitute): Use \& to represent this part of the
5320 string which was matched by the whole regexp, instead of
5321 representing the whole string. Any usage of \0 issues a warning
5322 and acts like \&, it will disappear in some subsequent release.
5324 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
5326 * m4.c: Complete prototype for forwarded declaration of usage.
5328 * input.c (init_macro_token): Correct own reference in error
5329 message. Previous name get_macro_func was referred to instead.
5330 (next_char): Correct own reference in error message. Previous
5331 name advance_input was referred to instead.
5333 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
5334 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
5335 and_term, not_term, logical_not_term, cmp_term, shift_term,
5336 add_term, mult_term, exp_term, unary_term, simple_term): Add
5337 prototype to forwarded declarations. Declare parameter v1 as
5338 eval_t * instead of int *. Same for local variable v2 in dyadic
5339 functions. Same for result in exp_term.
5340 * builtin.c (m4_eval): Declare value as eval_t instead of int.
5341 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
5342 unsigned_eval_t instead of unsigned int. Change casts accordingly.
5343 (shipout_int): Cast first argument of ntoa to eval_t.
5344 Reported by Thorsten Ohl.
5346 * macro.c: Complete the prototypes of forwarded expand_macro and
5348 Reported by Thorsten Ohl.
5350 * m4.h: Define voidstar as void * or char * depending on __STDC__.
5351 The Ultrix 3.1 compiler cannot do much with void pointers.
5353 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
5354 * m4.c (xfree): Replace void * by voidstar.
5355 Reported by Tom McConnell.
5357 * ansi2knr.1: New, from elsewhere.
5358 * Makefile.in (DISTFILES): Distribute ansi2knr.1
5360 * Makefile.in (stamp-h.in): Avoid running ./config.status if
5361 stamp-h does not exist yet. This avoids running it a second time
5362 just after the initial ./configure.
5363 Reported by David MacKenzie and Tom McConnell.
5365 * m4.h: Replace the enum debug_info declaration with a series of
5366 #define's. The Ultrix 3.1 compiler would otherwise need casting
5367 (int) to most references, when used in expressions.
5368 Reported by Tom McConnell.
5370 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
5372 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
5373 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
5374 calls the compiler. Previously, FP_PROTOTYPES was only calling
5375 the preprocessor; by not being subject to CFLAGS, this was
5376 discouraging those flags asking for ANSI compilation.
5377 * acconfig.h: Document HAVE_PROTOTYPES.
5378 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
5379 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
5380 Reported by Eric Backus.
5382 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
5383 from the environment. Default CFLAGS to -g if not set.
5384 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
5385 * lib/Makefile.in: Have CFLAGS substituted from configure.
5386 Reported by Eric Backus and Tom McConnell.
5388 * configure.in: m4_undefine changeword before using AC_ENABLE.
5390 * m4.h: Declare prototypes for error (for ANSI compilers only),
5391 prefix_all_builtins and reference_error.
5392 Reported by Tom McConnell.
5394 * input.c (set_word_regexp): Do not try to initialize the array
5395 test from a string, this does not work with non-ANSI compilers.
5396 Reported by Eric Backus.
5398 * Makefile.in (dist): Clean examples/ before saving it.
5399 (distclean-local): Also remove stamp-h.
5400 Reported by Eric Backus.
5402 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
5404 Reported by Tom McConnell.
5406 * checks/Makefile.in (clean): Depends on mostlyclean.
5407 (mostlyclean): New goal.
5409 1994-06-24 François Pinard <pinard@iro.umontreal.ca>
5411 * Makefile.in (DISTFILES): Distribute install.sh.
5412 * install.sh: New file, copied from elsewhere.
5413 Reported by Assar Westerlund and Kaveh R. Ghazi.
5415 1994-06-23 François Pinard <pinard@iro.umontreal.ca>
5417 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
5418 * acconfig.h: Explain ENABLE_CHANGEWORD.
5420 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
5421 from code provided by Pete Chown]
5422 * m4.h: Add original_text field to u_t variant of union u.
5423 Declare TOKEN_DATA_FUNC macro.
5424 * builtin.c: Declare changeword.
5425 (m4_changeword): New function.
5426 * input.c: Include "regex.h", define variables with word regexps.
5427 (input_init): Initialize the word regexp.
5428 (set_word_regexp): New.
5429 (next_token): Declare local variables, use the previous code if
5430 default_word_regexp is true. Else, match using a new code. Save
5432 * macro.c (expand_token): Ship out original text if not a macro
5434 Reported by Krste Asanovic and Pete Chown.
5436 [These modifs all depend upon ENABLE_CHANGEWORD]
5437 * m4.h: Declare external user_word_regexp.
5438 * m4.c: Declare user_word_regexp, and initialize it from
5439 --word-regexp or -W, or NULL if not specified.
5440 * input.c: Use user_word_regexp if specified, instead of
5441 DEFAULT_WORD_REGEXP.
5443 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
5446 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
5447 * checks/Makefile.in: Empty the suffix list.
5448 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
5450 * m4.c: Declare nesting_limit and initialize it to 250.
5451 Implement -LNUMBER or --nesting-limit=NUMBER to change its
5453 * m4.h: Declare nesting_limit as external.
5454 * macro.c (expand_macro): Stop execution whenever nesting limit
5456 Reported by Bengt Mertensson.
5458 * eval.c (evaluate): Diagnose excess characters in eval input.
5459 Things like `eval(08)' used to return 0 with no diagnostic.
5461 * m4.h: Capitalize first letter of all macro arguments in
5464 * m4.c: Declare warning_status, initialize it to 0. Add new
5465 option -E, or --fatal-warnings, which sets warning_status to
5466 EXIT_FAILURE instead.
5467 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
5468 EXIT_FAILURE if not otherwise done by header files.
5469 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
5470 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
5471 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
5472 argument of all M4ERROR calls.
5473 Reported by Noah Friedman.
5475 * examples/incl-test.m4: Renamed from incl_test.m4.
5476 * examples/include.m4: Include incl-test.m4 instead of
5478 * examples/multiquotes.m4: Renamed from multi-quotes.m.
5480 1994-06-22 François Pinard <pinard@iro.umontreal.ca>
5482 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
5483 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
5484 also tested it on a Sun Sparc workstation running SunOS 4.x.
5486 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
5487 49.format check, abusing a `union values' argument with sprintf
5488 without selecting the proper field. Now, save the formatting type
5489 first, delaying the fetch of the corresponding argument.
5490 Reported by Joseph E. Sacco and Tom Quinn.
5492 * format.c (format): Remove const from char *fmt declaration when
5493 not HAVE_EFGCVT, because a NUL may be forced into it.
5495 * m4.h: Declare atof() when not STDC_HEADERS.
5496 Reported by Joseph E. Sacco.
5498 * Regenerate configure using Autoconf 1.11, this corrects a
5499 problem about an incorrect cpp seting on NeXT 3.1.
5500 Reported by Alexander Lehmann.
5502 1994-06-05 François Pinard <pinard@iro.umontreal.ca>
5504 * m4.h (_): Change argument from `x' to `Args'.
5506 1994-04-22 François Pinard <pinard@iro.umontreal.ca>
5508 * m4.h: Rename Args() to _().

5514 * configure.in: Check for getrlimit, sigaction. If all of
5515 standard headers, getrlimit and sigaction, define USE_STACKOVF and
5516 substitute ${U}stackovf.o for STACKOVF.
5517 * acconfig.h: Declare USE_STACKOVF.
5518 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
5519 * m4.h: Declare setup_stackovf_trap().
5520 * m4.c: Call setup_stackovf_trap().
5521 * tests/stackovf_test.sh: New file.
5523 1994-04-13 François Pinard <pinard@iro.umontreal.ca>
5525 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
5527 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
5529 1994-01-30 <pinard@iro.umontreal.ca>
5531 * m4.h: Remove definition of volatile, not used anymore.
5532 Reported by Jim Meyering and Joseph E. Sacco.
5534 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
5535 of `if ... else /* nothing */' for if macros.
5536 Reported by Jim Meyering.
5538 * builtin.c (m4_regexp): Reorganize the code for avoiding a
5539 warning from gcc about `repl' possibly used before defined.
5540 Reported by Jim Meyering.
5542 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
5543 Reported by Jim Meyering.
5545 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
5547 * m4.h: Move the conditional definition of volatile after the
5548 inclusion of system files, because they may define it first.
5550 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
5552 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
5553 get around a problem with Alpha make seeing a syntax error, there.
5554 Reported by Vern Paxson.
5556 1994-01-03 François Pinard <pinard@iro.umontreal.ca>
5558 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
5559 Reported by Richard Stallman.
5561 1993-12-25 François Pinard <pinard@iro.umontreal.ca>
5563 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
5564 instead of AC_HAVE_FUNCS.
5565 Reported by Noah Friedman.
5567 1993-12-01 François Pinard <pinard@iro.umontreal.ca>
5569 * m4.c: Initialize show_help and show_version to zero.
5571 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
5572 Use them in exit() and usage() calls.
5574 1993-11-27 François Pinard <pinard@iro.umontreal.ca>
5576 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
5577 syserr() macro. Delete errref, add reference_error and M4ERROR.
5578 * m4.c: Replace errref, which was returning an input reference
5579 string, with reference_error, which prints it on standard error.
5580 * builtin.c, output.c: Use errno as second parameter to error,
5581 instead of using syserr() with %s.
5582 * *.c: Use M4ERROR instead of error: no more errref() with %s.
5583 Doing so, the program name appears after the input reference
5584 instead of before, which eases M-x next-error processing.
5586 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
5588 * checks/get-them: Escape braces with backslashes in patterns,
5589 because HPUX-9.01 awk needs this.

5598 Declare xrealloc, for use in errref().
5599 * m4.c: Delete error_message_prefix() function, add errref().
5600 * *.c: Use error() systematically in place of all error macros,
5601 now that error() flushes stdout first. Make needed adjustments.
5603 * m4.h: Remove const in sys_errlist[] declaration, it creates
5604 conflicts on SGI and Alpha.
5605 Reported by Kaveh R. Ghazi.
5607 1993-11-20 François Pinard <pinard@iro.umontreal.ca>

5621 1993-11-17 François Pinard <pinard@iro.umontreal.ca>
5623 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
5625 * input.c (input_init): Initialize quote and comment strings
5626 explicitely instead of calling set_quotes and set_comment: by
5627 doing so, we ensure we do not free uninitialized variables.
5629 * checks/check-them: Reverse arguments to both diff, so the
5630 expected is on the left and the obtained on the right.
5632 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
5633 macros. Delete declarations for m4error, warning, fatal and
5634 internal_error, add declaration for error_message_prefix.
5635 * m4.c: Delete m4error, warning, fatal and internal_error
5636 routines, add error_message_prefix routine.
5637 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
5638 warning with WARNING*, fatal with FATAL* and internal_error with
5640 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
5641 this is not needed anymore.
5643 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
5644 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
5645 and debug_message, add declaration for debug_message_prefix.
5646 * debug.c: Remove static specifier for FILE *debug declaration.
5647 Delete debug_print and debug_message routines, add
5648 debug_message_prefix routine.
5649 * builtin.c, debug.c: Replace debug_print routine calls with
5650 DEBUG_PRINT* macro calls.

5656 (trace_format): Use stdarg instead of varargs if __STDC__.
5658 * configure.in: Remove checks for vfprintf and _doprnt. These
5659 implementations use varargs tricks which are not portable enough.
5660 * lib/vfprintf.c: Deleted.
5661 * lib/_doprnt.c: Deleted.
5662 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.
5663 Reported by Joel Sherrill.

5682 Reported by Joel Sherrill.
5684 * builtin.c (prefix_all_builtins): Instead of the table size, use
5685 the null entry at end for stopping the loop. It was overwritten.
5686 Reported by Andreas Schwab and Jim Meyering.

5768 Reported by Jim Avera.
5770 * builtin.c (m4_ifelse): Diagnose excess arguments if 5, 8, 11,
5771 etc., arguments, then ignore the superfluous one. m4 used to

5878 * Makefile.in, lib/Makefile.in, check/Makefile.in: In dist goals,
5879 ensure 777 mode for directories, so older tar's will restore file
5882 1993-01-17 François Pinard <pinard@iro.umontreal.ca>
5884 * Makefile.in, lib/Makefile.in: Put $(CFLAGS) after $(CPPFLAGS),
5885 so the installer can override automatically configured choices.
5886 Reported by Karl Berry.
5888 1993-01-15 François Pinard <pinard@iro.umontreal.ca>
5890 * lib/vfprintf.c: Stolen from Oleo distribution and adapted. The
5891 previous version was not working properly on m68k-hp-bsd4.3.
5892 Reported by Roland McGrath.
5894 * lib/_doprnt.c: Stolen from Oleo distribution.
5895 * configure.in: Check for _doprnt.c if vfprintf.c selected.
5896 * lib/Makefile.in: Distribute _doprnt.c.
5897 Do not distribute regex.[ch].old anymore.
5899 1993-01-01 François Pinard <pinard@iro.umontreal.ca>
5901 * Makefile.in, lib/Makefile.in: Reinstate $(CPPFLAGS), use it.
5902 Richard wants it there.
5904 1992-12-27 François Pinard <pinard@iro.umontreal.ca>
5906 * Makefile.in: Add DEFS to MDEFINES.
5907 * lib/Makefile.in (.c.o): Remove $(CPPFLAGS).
5908 (libm4.a): Remove the library before creating it.
5909 (distclean): Remove tags and TAGS too.
5911 1992-12-23 François Pinard <pinard@iro.umontreal.ca>
5913 * Makefile.in (dvi, m4.dvi): New goals.
5915 * builtin.c, eval.c, format.c, input.c, m4.[ch], m4.texinfo,
5916 macro.c, output.c, path.c, symtab.c: Change Copyright from
5917 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
5919 * examples/divert.m4: Deleted, this bug has been corrected.
5921 * Makefile.in (texclean, mostlyclean): New goals.
5923 * Makefile.in (clean): Remove clutter from ansi2knr.
5924 Reported by Pierre Gaumond.
5926 1992-12-20 François Pinard <pinard@iro.umontreal.ca>
5928 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
5929 might well use CFLAGS is s/he needs it.

5934 Reported by David MacKenzie.
5935 Reported by Skip Montanaro.
5936 Reported by Erez Zadok.
5937 Reported by Assar Westerlund.
5939 1992-12-19 François Pinard <pinard@iro.umontreal.ca>
5942 This is still a beta release for the future GNU m4 version 1.1.
5944 * lib/alloca.c: New, from elsewhere.
5945 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
5947 * m4.h: Do not define index/rindex if already defined. If
5948 FALSE/TRUE are already defined, do not redefine them, but merely
5949 define boolean typedef to int.
5951 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
5952 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
5953 because some C compilers do not like connectives with #ifdef.
5954 * m4.h: Define `volatile' only if __GNUC__, instead of once for
5955 __GNUC__ and once for __STDC__.
5956 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
5958 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
5959 Makefile dependencies. Without it, make keeps destroying and
5960 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
5962 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
5963 to diversion/DIVERSION, this was a spelling error.
5965 * m4.c: Declare version[], remove #include "version.h".
5966 * version.h: Deleted.
5967 * Makefile.in: Remove references to version.h.
5969 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
5970 production, by using a simpler and more robust algorithm. This
5971 solves the problem of synclines sometimes written in the middle of
5972 an output line. Delete sync_line() and output_lines variable.
5973 * m4.h: Remove sync_line prototype and output_lines declaration.
5974 * input.c (next_char), output.c (shipout_text): Remove references
5976 * input.c (push_file, pop_file): Merely put the value -1 in
5977 output_current_line instead of calling sync_line, for delaying a
5978 single `#line NUM FILE' before next output line. Do not test
5979 for sync_output, because this is unnecessary clutter.
5980 * output.c (make_divertion, insert_divertion): Idem.
5981 * input.c: Rename must_advance_line to start_of_input_line, for
5984 * debug.c (trace_header): Select a new debug line format, which
5985 better complies with GNU standards for formatting error messages.
5986 With option `-dfl', M-x next-error might be used on the output.
5987 * m4.c (vmesg): Adjust format of error output to GNU standards.
5988 * m4.texinfo: Adjust examples for `make check' to work.
5990 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
5991 case for enum debug_info constants, which were all lower case.
5993 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
5995 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
5996 collected patches. I tried a few times using newer regex.[ch], it
5997 mysteriously stopped aborting with this one. Insecure feeling...
5998 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
6000 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
6002 * m4.c: Change `--no-warnings' to `--silent'.
6003 Reported by David MacKenzie.
6005 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
6006 leave it off for now. See comment in m4.c for justification.
6007 Reported by David MacKenzie.
6009 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
6010 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
6012 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
6014 * Makefile.in: Ensure recursive cleaning is done before local
6015 cleaning for all clean goals.
6017 * builtin.c (ntoa): Ensure the value is always interpreted as a
6018 signed quantity, whatever the radix is.
6020 1992-11-18 Jim Meyering <meyering@idefix>
6022 * builtin.c, format.c, input.c: Split long lines.
6023 * m4.c: Use typedef macro_definition instead of struct
6025 * symtab.c: Use typedef symbol instead of struct symbol.
6027 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
6029 * *.[ch]: Remove all trailing whitespace, in code and comments.
6031 * configure.in: Find some awk.
6032 * Makefile.in: Add $(AWK) to MDEFINES.
6033 * checks/Makefile.in: Transmit $(AWK) to get_them.
6034 * checks/get_them: Use $AWK instead of gawk. Add a close in the
6035 awk script when switching files, because without this, mawk runs
6036 out of file descriptors.
6038 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
6040 * Makefile.in (realclean): Delete m4.info*.
6041 Reported by Jim Meyering.
6043 * Makefile.in: Adjust and link with checks/Makefile.
6044 * checks/Makefile.in: New.
6045 * configure.in: Output checks/Makefile.
6047 * checks/get_them: Have the dnl header of each test more
6048 recognizable by next-error, also use a better message.
6050 1992-11-16 Jim Meyering <meyering@idefix>
6052 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
6053 And use that only if __GNUC__ since we're using it's GCC-specific
6054 semantics that tell the compiler the associated function doesn't
6057 * builtin.c (substitute): Don't use character as an array index.
6058 (dumpdef_cmp): Make formal arguments `const void *' to avoid
6059 warnings with gcc -W -Wall on systems with qsort prototype.
6060 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
6063 * eval.c (most functions): Add parentheses to assignments used
6064 as truth values go avoid warnings from gcc -Wall.
6066 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
6067 any functions that don't need external scope.
6069 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
6070 (many functions and arrays): Declare `const'.
6072 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
6074 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
6075 removing the declaration from m4.h. Also rename false to FALSE
6078 * lib/Makefile.in (Makefile): New goal.
6080 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
6081 so heavily loaded. It gets more easily overridable, calling make.
6082 Reported by Jim Meyering.
6084 * Makefile.in (dist): Get .fname from the current directory name,
6085 instead of from version.h. I need updating many files manually,
6086 when the version changes, version.h is just one of them.
6088 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
6090 * m4.h: Remove the tag `boolean' on the enum introducing typedef
6091 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
6092 Reported by Tom McConnell.
6094 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
6096 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
6097 39.cleardiv, which were describing missing or spurious newlines.
6098 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
6099 do not depend on machine word size, `/bin/false' implementation,
6100 or `wc' output format. `make check' is more dependable, now.
6102 * checks/check_them: Summarize the failed tests by listing their
6103 name, at end. If none, issue `All checks successful'. Output
6104 `Checking' instead of `Input file:'.
6106 * checks/get_them, checks/check_them: Reindented.
6108 * Makefile.in (dist): chmod a+r before making the tar file.
6110 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
6112 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
6114 * input.c (next_token): Reinitialize token_buttom just after using
6115 it as a watermark with obstack_free. Or else, a future token, big
6116 enough for triggering reallocation of the obstack chunk, could
6117 void the initialized value of token_buttom, later causing panic in
6118 obstack_free. Rename token_buttom to token_bottom everywhere.
6120 * m4.h: Before declaring errno, first include <errno.h> and
6121 ensure that it does not define errno.
6122 Reported by Richard Stallman.
6124 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
6126 * builtin.c: Define and use DECLARE macro for builtins.
6128 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
6129 argument, this is a common idiom for introducing long comments.
6131 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
6132 arguments. The last argument was silently ignored.
6134 * m4.c (cmd_error): Add a missing semicolon before va_end().
6136 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
6138 * Makefile.in: Now handle protoized sources. Define and use U.
6139 Compile and use ansi2knr with old compilers. Update DISTFILES.
6140 Add `aclocal.m4' to `configure' dependencies.
6141 * ansi2knr.c: New, from Ghostscript distribution.
6142 * configure.in: Define U through FP_PROTOTYPES for old compilers.
6143 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
6144 * aclocal.m4: New, provide FP_PROTOTYPES.
6145 * m4.h: Conditionnaly protoized through Args, save for varags.
6146 * builtin.c: Protoized. Then:
6147 Include <sys/types.h> if size_t is not defined, before "regex.h".
6148 (m4_ifelse): Fetch built-in name properly for diagnostic.
6149 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
6150 (m4_regexp): Add const to `msg' declaration.
6151 (m4_patsubst): Add const to `msg' declaration.
6152 * debug.c: Protoized, save for varargs.
6153 * eval.c: Protoized.
6154 * format.c: Protoized.
6155 * input.c: Protoized.
6156 * m4.c: Protoized, save for varargs. Then:
6157 (xfree): Accept void * instead of char *.
6158 (xmalloc): Return void * instead of char *.
6159 (xrealloc): Accept and return void * instead of char *.
6160 * macro.c: Protoized.
6161 * output.c: Protoized.
6162 * path.c: Protoized. Then cast some (char *) over xmalloc's.
6163 * symtab.c: Protoized.
6165 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
6167 * m4.texinfo: Remove directory from diagnostics in 30.include,
6168 51.eval, 56.errprint and 57.m4exit tests.
6170 * m4.h: Remove declarations for int or void system functions, they
6171 cause more conflicting trouble than they make good.
6173 * configure.in: Avoid configuration header file. Add some tests.
6174 * m4.h: Remove #include "config.h".
6175 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
6176 Then, rewritten for better compliance with GNU standards.
6178 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
6180 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
6181 because of a misplaced #endif.
6183 * Many *.[hc] files: Correct intra-line spacing here and there,
6184 according to GNU indent 1.6 advice.
6186 * configure.in: New, using Autoconf 1.2.
6187 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
6188 * Delete old configure.in, configure, etc/configure.in,

6203 * checks/get_them: New location for etc/get_examples.
6204 * checks/check_them: New location for etc/check_examples.

6210 1992-03-10 François Pinard <pinard@iro.umontreal.ca>
6212 * Makefile.in (check): Add m4 as dependency.
6214 * m4.c: Accept --no-warnings instead of --no_warnings, and
6215 --no-gnu-extensions instead of --no_gnu_extensions. Make the
6216 usage message more informative.
6217 Reported by David MacKenzie.

6232 * m4.h: Delete definitions for abort() and exit().
6233 Reported by Richard Stallman.
6235 * config/hmake-unicos, config/s-unicos.h: New files.
6236 Reported by Hal Peterson.
6238 * eval.c (exp_term): Have N^0 return 1.
6239 Reported by Michael Fetterman.
6241 * eval.c, input.c, m4.h: Remove last comma in enums.
6242 Reported by Mike Lijewski.

6260 * The built-in format can now be configured to use sprintf as
6261 the formatting engine, for systems without [efg]cvt(3).
6263 * GNU library code is moved to the ./lib subdirectory; other
6264 utility files are now in ./etc.

6280 considerably. See the manual for details.
6282 * The -tMACRO option is added, marks MACRO for tracing as soon
6285 * Builtins are traced after renaming iff they were before.
