1 2005-05-06 Gary V. Vaughan <gary@gnu.org>
3 * configure.ac (gl_MODULES): Add assert to support a
4 --disable-assert configure time option for NDEBUG setting.
6 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.
7 * bootstrap (src_modules): Add version-etc-fsf.
8 * src/main.c (version_etc_copyright): Removed.
10 * ltdl/m4/m4-getopt.m4 (m4_GETOPT): Synch with gnulib/getopt.m4.
12 2005-05-04 Gary V. Vaughan <gary@gnu.org>
14 * src/m4.h (__CYGWIN__, WIN32): Canonicalise Windows and Cygwin
16 * src/freeze.c (produce_frozen_state): Use \n line-endings even
17 on Windows, so that the frozen file reader will work.

20 2005-05-04 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
22 Forward port of a patch that allowed m4-1.4.2 to compile on
25 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
27 * src/m4.h: And include them as appropriate.
28 * src/main.c, src/stackovf.h: Don't include signal.h literally;
29 m4.h will include the correct file.
31 2005-05-04 Gary V. Vaughan <gary@gnu.org>
33 * m4/m4private.h: Make errno visible for the sources patched
36 2005-05-04 Paul Eggert <eggert@twinsun.com>
38 * src/main.c (print_program_name_CB): Preserve errno, since
39 M4ERROR relies on this.
40 * modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
41 * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
42 * m4/path.c (m4_path_search): Don't let "free" trash errno when
45 * m4/output.c (m4_insert_file): Don't assume errno has a valid
46 value simply because fread returns zero. This fixes a
47 portability bug reported by Marion Hakanson in
48 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
50 2005-05-04 Santiago Vila <sanvila@debian.org>
52 * tests/stackovf.test: Use tempfile if available.

56 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=92629
57 * m4/output.c (m4_insert_file): Do not mix buffered and
58 unbuffered I/O, as this breaks on the Hurd.
60 2005-05-04 Gary V. Vaughan <gary@gnu.org>
62 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
63 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
64 and libtoolize does a better job of ltdl importing now too, so
65 take advantage of that while updating the tree:
67 * acm4, config: Moved from here...
68 * ltdl/m4, ltdl/config: ...to here.
69 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
70 src/Makefile.am, tests/Makefile.am: Removed...
71 * Makefile.am: ...and migrated to here, with adjustments to
72 compensate for relative path differences.
73 * commit: Adjust relative paths.
74 * configure.ac: Adjust relative paths.
75 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
77 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
78 the meanwhile, CVS HEAD libtool is needed.
79 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
80 stricly new enough, we also need a patch.
81 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
82 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
83 (gl_MODULES): Don't list getopt and version-etc, as they don't
85 * bootstrap: After running gnulib-tool to import the listed
86 modules, fetch getopt and version-etc into src manually.
87 (ltdldir): Change to ltdl.
88 * src/main.c: Adjust for changes in version-etc API.
89 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
90 but works when the getopt module isn't to be included in the lib.
91 * README: Add note about patching autoconf and automake to
94 2005-05-02 Matt Kraai <kraai@debian.org> (tiny change)
96 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=84416
97 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
98 empty file rather than to a nonexistent file. This closes a
100 * modules/m4.c (m4_maketemp): Implement the above, by using
101 mkstemp rather than mktemp.
103 2005-05-01 Gary V. Vaughan <gary@gnu.org>
105 The FSF are moving offices today. Changed their contact address
106 in all files from `59 Temple Place, Suite 330, MA 02111-1307' to
107 `51 Franklin Street, Fifth Floor, MA 02110-1301'.
109 2005-03-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
111 * tests/Makefile (clean-local): Ignore testsuite cleanup
114 2005-03-11 Per Bothner <per@bothner.com> (tiny change)
116 * tests/Makefile (clean-local): Only run the testsuite cleanup
117 if the testsuite has been generated.
119 2005-02-11 Stepan Kasal <kasal@ucw.cz>
121 * TODO: slight clarification of the example of qindir usage.
123 2005-02-08 Gary V. Vaughan <gary@gnu.org>
125 * TODO: Add qindir requirement, and defn bug.
126 From Stepan Kasal <kasal@ucw.cz>
128 2005-02-08 Stepan Kasal <kasal@ucw.cz>
130 * TODO: Add ``execution stack'', fix a typo.
131 * doc/m4.texinfo: Typos.
133 2004-12-24 Eric Blake <ebb9@byu.net>
135 * configure.ac (INCLUDE_STDBOOL_H): Account for gnulib's move
136 to the gnu subdirectory.
137 * acm4/m4-error.m4 (INCLUDE_ERROR_H): Likewise.
138 * acm4/m4-obstack.m4 (INCLUDE_OBSTACK_H): Likewise.
139 * acm4/m4-regex.m4 (INCLUDE_REGEX_H): Likewise.
140 * m4/system_.h: Likewise, in non-configured includes.
142 2004-10-14 Noah Misch <noah@cs.caltech.edu>,
143 Gary V. Vaughan <gary@gnu.org>
145 * m4/m4.c (m4_context_field_table, m4_context_opt_bit_table):
146 Protect definitions from macro expansion under -DNDEBUG by
147 parenthesising the expanded function names.
148 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
149 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
150 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
151 (m4_is_syntax_macro_escaped): Similarly protect function
152 definitions from macro expansion under -DNDEBUG by #undefing the
153 matching macro names before each definition. Also, move all the
154 function definitions to the end of the file so that any
155 invocations in the rest of the file pick up the fast macro
157 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)
158 (m4_set_debug_file, m4_set_trace_messages)
159 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
160 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
161 (m4_set_max_debug_arg_length_opt): New fast macro versions of the
162 option setter functions.
164 2004-09-23 Gary V. Vaughan <gary@gnu.org>
166 * src/main.c: Include gnulib files from the correct directory.
168 * gnulib/*: Don't store any of the gnulib files in arch, as they
169 generate spurious changes.
170 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
171 gnulib macros now share our macro directory.
172 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
173 * bootstrap: Call gnulib-tool to import from the gnulib tree.
174 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
175 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
176 the gettext macros from autopoint that overwrite the gnulib-tool
177 imported versions. Import sources and Makefile.am into the `gnu'
178 directory. Changed all callers.
179 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
180 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
181 for imported modules.
182 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
183 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
184 hardcoding the gnulib macros they wrap.
186 2004-07-15 Gary V. Vaughan <gary@gnu.org>
188 Latest CVS libtool can preload modules in libraries, including
189 its own module loaders! Tweak m4 so that it doesn't try to treat
190 libltdl's module loaders as m4 modules when freezing and on exit:
192 * gnulib/acm4/*.m4: Don't store these files in arch since they
193 generate spurious changes.
194 * bootstrap: Simplify initial libtoolize call, since CVS
195 libtoolize is smarter these days.
196 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
198 * m4/module.h (m4__module_exit): Missing declaration.
199 * m4/m4private.h (m4__module_next): New function declaration.
200 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
201 encapsulation. Changed all callers.
202 (m4__module_interface): New function to verify m4 loadable module
204 (m4__module_init): Register the interface validator.
205 (m4__module_exit): Only close my own modules.
206 * modules/m4.c (unistd.h): Provide missing declaration.
207 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
208 (m4_expand_ranges): More missing declarations.
209 * modules/modtest.c (export_test): Ditto.
210 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
211 * src/main.c (main): Bump copyright year.
212 * tests/modules.at: Fix sed syntax error.
215 2004-06-17 Gary V. Vaughan <gary@gnu.org>
217 Tweaking to enable compilation with latest CVS libtool and
218 libltdl. We can't just dump the library files directly into the
219 m4 directory anymore now that libltdl is built from pieces itself:
221 * bootstrap: Rewritten to use latest libtoolize sanely, and to
222 set up libltdl subdirectory.
223 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
224 gnulib subdirectory's config.
225 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
226 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
228 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
229 configure.ac, so use AC_WITH_LTDL instead.
230 * Makefile.am (SUBDIRS): Add libltdl.
231 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
233 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
234 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
235 (libm4_la_LIBADD): Add LIBLTDL.
236 * m4/ltdl.c, m4/ltdl.h: Removed.
237 * m4/m4module.h: Include canonical ltdl.h.
240 2004-06-14 Gary V. Vaughan <gary@gnu.org>
242 * gnulib/import: Now updates makefile fragments, and configure.ac.
243 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
244 * gnulib/m4/Makefile.am: include it.
245 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
246 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
247 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
248 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
249 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
250 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,
251 gnulib/acm4/lib-ld.m4, gnulib/acm4/lib-prefix.m4,
252 gnulib/acm4/error.m4, gnulib/acm4/po.m4, gnulib/acm4/regex.m4,
253 gnulib/acm4/stdbool.m4, gnulib/acm4/stdint_h.m4,
254 gnulib/acm4/uintmax_t.m4, gnulib/acm4/ulonglong.m4,
255 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
256 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
257 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
259 * gnulib/m4/getopt_int.h: New source file from latest gnulib
261 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
262 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,
263 gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
264 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
265 Updated source files from latest gnulib.
267 2004-02-29 Gary V. Vaughan <gary@gnu.org>
269 * config/mailnotify: New file for mailing commit notifications,
270 imported from cvs-utils.
271 * commit: Updated from cvs-utils and tweaked for m4.
273 2003-12-01 Gary V. Vaughan <gary@gnu.org>
275 * config/mkstamp: Updated from CVS libtool.
276 * configure.ac: Generate a gnu coding standards compliant version
277 number, and use it for the banner.
278 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
279 mhen the TIMESTAMP changes in ChangeLog, but the file modification
280 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
281 contain the previous version number.
282 * src/main.c: Make --version output conform to the GNU standard.
284 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
285 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
286 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
287 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
288 time_la_SOURCES): ...so that these are defaulted correctly, and
289 can be removed from this file.
290 (AM_LDFLAGS): Add -module...
291 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
292 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
293 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
294 the individual settings can be removed.
295 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
296 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
297 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
298 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
299 time_la_LIBADD): ...so that these are picked up as a deplib of
300 libm4 and don't need to be set explicitly.
302 2003-11-18 Gary V. Vaughan <gary@gnu.org>
304 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
305 from the standard build. It is too fragile.
307 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
308 CVS libtool after merging m4 changes across to libtool.
310 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
311 * m4/path.c (search_path_add): Ditto.
313 2003-11-13 Gary V. Vaughan <gary@gnu.org>
315 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
316 libtool tags we don't use in configure. This reduces the size
317 of the script from over 1Mb to under 700Kb.
319 2003-11-13 Gary V. Vaughan <gary@gnu.org>
321 The import script was not written properly, and the last gnulib
322 import was incomplete. Fixed that problem, and reimport our
323 gnulib dependencies, which picks up the address calculation
324 overflow checks described by Paul below. Also tweak the clients
325 of the gnulib xalloc module not to use deprecated macros:
327 * gnulib/import: Recurse through module dependencies rather than
328 naively descending only one level.
329 * configure.ac: Add calls to gnulib's strnlen and extension module
331 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
333 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
334 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
335 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
336 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
338 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
339 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
340 place of `xcalloc (1, S)'.
341 * m4/m4.c (m4_create): Likewise.
342 * m4/m4private.h (m4_symbol_value_create): Likewise.
343 * m4/symtab.c (symtab_fetch): Likewise.
344 * m4/syntax.c (m4_syntax_create): Likewise.
345 * src/freeze.c (reload_frozen_state): Likewise.
346 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
348 * m4/symtab.c (m4_symtab_create): Likewise.
350 2003-11-13 Gary V. Vaughan <gary@gnu.org>
352 * tests/module.at: Comment typo.
354 2003-10-10 Gary V. Vaughan <gary@gnu.org>
356 * tests/modules.at (modules: importing): Apply some lateral
357 thinking, and use AT_CHECK to compare the output of a sed pass
358 over stderr against the canonical strerror string.
360 * tests/modules.at (modules: importing): Edit the generated stderr
361 output to canonicalize strerror output, before a comparison.
363 2003-10-10 Gary V. Vaughan <gary@gnu.org>
365 Tru64UNIX perl is sloppy with namespace pollution. This patch is
366 careful not to trip over the mess:
368 * modules/perl.c: Some builds of perl install headers that contain
369 `#define try __builtin_try'. Be sure to undefine that macro
370 before `m4/hash.h' gets included, which uses the `try' symbol.
371 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
372 `false' before including `stdbool.h'.
373 (DELETE): This symbol is not in m4's namespace, and is in any
374 case only used internally...
375 * m4/m4private.h (DELETE): ...so move it to here.
376 Reported by Martin MOKREJS <mmokrejs@natur.cuni.cz>
378 2003-10-08 Paul Eggert <eggert@twinsun.com>
380 Don't use XMALLOC and XCALLOC. Once we install the
381 corresponding patch into gnulib, this will fix some
382 address-calculation overflow bugs on hosts where calloc (A, B)
383 returns garbage when A*B overflows.
385 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
386 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
387 xmalloc, XCALLOC with xcalloc.
388 * m4/m4.c (m4_create): Likewise.
389 * m4/m4private.h (m4_symbol_value_create): Likewise.
390 * m4/output.c (m4_output_init): Likewise.
391 * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise.
392 * m4/syntax.c (remove_syntax_attribute): Likewise.
393 * src/freeze.c (reload_frozen_state): Likewise.
394 * src/main.c (main): Likewise.
396 2003-10-07 Gary V. Vaughan <gary@gnu.org>
398 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
399 gnulib/acm4 directories for aclocal m4 macros.
400 * gnulib/Makefile.am (EXTRA_DIST): Removed.
401 (MAINTAINERCLEANFILES): Add Makefile.in.
402 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
404 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
405 * gnulib/import: New file. Temporary script for updating gnulib
406 imported files, until gnulib-tool is working.
407 * gnulib/config/codeset.m4, gnulib/config/error.m4,
408 gnulib/config/exitfail.m4, gnulib/config/extensions.m4,

453 gnulib with gnulib/import script.
454 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
455 guards ready for gnulib-tool to autoupdate on import.
456 * config/debug.m4, config/gmp.m4, config/m4-error.m4,
457 config/m4-gettext.m4, config/m4-obstack.m4, config/m4-regex.m4,
458 config/stackovf.m4: Moved from here...

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

465 m4/path.c, m4/symtab.c, m4/syntax, m4/system_.h, modules/m4.c,

470 (version_etc): Call with new variadic API.
472 2003-09-16 Gary V. Vaughan <gary@gnu.org>
474 * gnulib/m4/version-etc.c, gnulib/m4/version-etc.h: Import
475 version-etc module from CVS gnulib.
476 * po/POTFILES.in: Add gnulib/m4/version-etc.c.
477 * src/Makefile.am: Build it.
478 * src/main.c: Use it.
480 * gnulib/m4/exit.h: Import exit module from CVS gnulib.
481 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
482 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
485 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
486 Gary V. Vaughan <gary@gnu.org>
488 * bootstrap: Separate options.
489 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
490 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
492 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
493 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
494 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
495 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
496 $(LTLIBINTL) for gettext support on cygwin.
497 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
498 have $(LTLIBINTL) from the preloaded module la files.
499 * README: Remove the warning about using --disable-nls on Windows
502 2003-09-15 Gary V. Vaughan <gary@gnu.org>
504 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
505 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
508 2003-09-12 Gary V. Vaughan <gary@gnu.org>
510 * doc/STYLE: Document the gnulib header naming conventions, and
512 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
513 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,
514 gnulib/m4/gettext.h, gnulib/m4/obstack.h, gnulib/m4/regex.h
516 * gnulib/m4/Makefile.am: Remove the rules to build these headers.
518 * gnulib/m4/strtol.c, gnulib/config/strtol.m4: Import strtol
519 module from CVS gnulib.
520 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
521 (gl_FUNC_STRTOL): In favour of the module macro.
523 2003-09-12 Gary V. Vaughan <gary@gnu.org>
525 Replace the getopt code with CVS gnulib getopt. The source files
526 detect whether they are in a glibc environment and preprocess away
527 all of the code if there is a system getopt, so we can compile
528 them into the m4 executable unconditionally:
530 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
531 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
532 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
534 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
536 * src/Makefile.am: Adjust.
537 * src/main.c: Always include our shipped getopt.h.
538 * po/POTFILES.in: Use new location of getopt.c.
540 2003-09-12 Gary V. Vaughan <gary@gnu.org>
542 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
543 * config/Makefile.am: Removed. Automake 1.8 distributes the files
544 in this directory automatically.
545 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
547 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
549 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
551 * modules/Makefile.am (pkglibexecdir): Set it here.
552 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
554 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
555 Import regex module from CVS gnulib.
556 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
557 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
558 do extra substitutions for Makefile.
559 * configure.ac: Use it.
560 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
561 from regex_.h if necessary.
562 * m4/system_.h: Include the correct version of regex.h.
563 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
565 * po/POTFILES.in: Use new location of regex.c.
567 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
568 realloc.c: automake distributes these files already.
570 2003-09-12 Gary V. Vaughan <gary@gnu.org>
572 Replace the xstrzdup code by importing the xstrndup module from
573 CVS gnulib, along with its dependencies: strndup and strnlen:
575 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
576 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
578 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
579 gnulib/config/strndup.m4: Ditto wrt strndup.
580 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
582 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
583 However, contrary to gnulib, we install xstrndup.h.
584 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
585 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
586 is an artifact of the old m4 portability layer.
587 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
588 * m4/system_.h: Include xstrndup.h.
589 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
591 2003-09-11 Gary V. Vaughan <gary@gnu.org>
593 Reimport the latest xalloc module from CVS gnulib, and adjust the
594 m4 sources to take advantage of xalloc xfree. Also create a new
595 macro DELETE with the same semantics as the old m4 XFREE macro,
596 and carefully tweak callers:
598 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
600 * m4/utility.c (xfree): Removed. This function is now supplied by
602 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
603 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
604 * m4/symtab.c (m4_symtab_create): Ditto.
605 * m4/system_.h: Removed XFREE redefine.
606 (DELETE): New macro with same functionality as the original m4
607 XFREE macro, but based on xalloc.h now. Changed all callers.
608 * src/main.c (main): Use XMALLOC macro.
609 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
611 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
613 2003-09-10 Gary V. Vaughan <gary@gnu.org>
615 Import the xalloc module from CVS gnulib, along with its
616 dependencies: exitfail, malloc and realloc. We had different
617 semantics for our XFREE and a function xfree() not supplied by
618 gnulib, so also a bit of work to keep everything running
621 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
622 (gl_XALLOC): Use gnulib equivalents.
623 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
624 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
625 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
626 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
628 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
629 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
630 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
632 (pkgincdir): Removed. Use pkgincludedir instead.
633 * m4/m4private.h (XFREE): xfree already checks for NULL.
634 * m4/system_.h: Use xalloc module, and remove macros already
635 supplied by xalloc.h.
636 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
637 moved the old definition from m4/xmalloc.c to here for now.
639 2003-09-09 Gary V. Vaughan <gary@gnu.org>
641 Import the error and progname modules from CVS gnulib. Our old
642 error.c subsumed the functionality of both, so a little adjustment
643 was required to accomodate the split in sources. Also added more
644 wrapper macros to choose between a system installed error.h or our
645 shipped gnulib error module:
647 * m4/error.c, m4/error.h: Removed.
648 * m4/Makefile.am: Adjust.
649 (pkgincdir): Removed. Use pkgincludedir instead.
650 * m4/module.h, src/main.c: Don't include `m4/error.h'.
651 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
653 * gnulib/m4/progname.c: Imported from CVS gnulib.
654 * gnulib/m4/progname.h: Ditto.
655 * src/main.c: Adjust to use progname module.
656 * gnulib/m4/error.c: Imported from CVS gnulib.
657 * gnulib/m4/error_.h: Ditto.
658 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
659 if appropriate, and link a local error.h if the system version is
661 (libgnu_la_SOURCES) Add progname module sources.
662 * gnulib/config/error.m4: Imported from CVS gnulib.
663 * gnulib/config/strerror_r.m4: Ditto.
664 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
665 to have ERROR_H for Makefile substitutions and tell system.h
666 whether the system error.h should be used, or a locally installed
668 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
670 2003-09-09 Gary V. Vaughan <gary@gnu.org>
672 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
673 s/gettext_.h/gettext.h/.
675 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
676 automake have been fixed.
678 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
679 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
680 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
681 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
683 2003-09-09 Gary V. Vaughan <gary@gnu.org>
685 The gnulib obstack module requires the gnulib gettext module for
686 systems that do not have GNU gettext installed. Because we use
687 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
688 that directory incase it clashes with the system gettext.h. This
689 delta uses gettext_.h and extra rules in the Makefile to make a
690 link to gettext.h when needed:
692 * Makefile.am (auxdir): Removed. No longer used.
693 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
694 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
696 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
697 Makefile based build.
698 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
699 of the macros are kept.
700 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
701 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
702 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
703 distributes these automatically.
704 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
705 warning from automake-1.7a.
706 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
707 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
709 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
710 wrt. m4_FUNC_OBSTACK.
711 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
712 wrt. m4_sys_STACKOVF.
713 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
714 wrt. _m4_LIB_GMP, m4_LIB_GMP.
715 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
716 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
718 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
719 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
720 gettext.h link on deficient systems.
721 (pkginc_HEADERS): Mention $(GETTEXT_H).
722 (EXTRA_HEADERS): Mention gettext.h.
723 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
724 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
725 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
726 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
727 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
728 gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
729 gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
730 gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
731 gnulib/config/po.m4, gnulib/config/progtest.m4,
732 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
733 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
735 2003-09-05 Gary V. Vaughan <gary@gnu.org>
737 We can't mirror the gnulib directory structure here, since we need
738 to be able to eg. `#include <m4/obstack.h>' from our source files,
739 which is much easier if the local obstack.h is created in a
740 directory named m4. Rather than trying to symlink everything into
741 the m4 directory, now we build a libtool convenience library from
742 the sources we get from gnulib and link that with libm4.la:
744 * gnulib/config/extensions.m4: Imported from CVS gnulib.
745 * gnulib/config/unlocked-io.m4: Ditto.
746 * gnulib/m4/unlocked-io.h: Ditto.
747 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
748 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
749 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
750 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
751 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
752 * m4/Makefile.am: Adjust.
753 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
754 macros we redistribute.
755 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
756 library among others.
757 (GNULIB_SRCS, GNULIB_MACROS): Removed.
758 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
759 * config/m4-obstack.m4: Adjust.
760 * po/POTFILES.in: Adjust.
761 * configure.ac: Reformatting. Call newly imported gnulib macros.
762 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
763 bogus calls of `#include "m4.h"'.
764 * Makefile.am: INCLUDES has been deprecated in favour of
766 * m4/Makefile.am: Ditto.
767 * modules/Makefile.am: Ditto.
768 * src/Makefile.am: Ditto.
770 2003-09-05 Gary V. Vaughan <gary@gnu.org>
772 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
774 2003-09-04 Gary V. Vaughan <gary@gnu.org>
776 Migrate the obstack support into the gnulib directories for easy
777 synchronisation with upstream files in gnulib:
779 * config/gnu-obstack.m4: Moved from here...
780 * config/m4-obstack.m4: ...to here.
781 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
782 * m4/obstack.c, m4/obstack_.h: Moved from here...
783 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
784 * po/POTFILES.in: Adjust.
785 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
786 * m4/Makefile.am: Add a whole new section to link the obstack
787 sources from the gnulib tree if necessary.
788 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
790 * config/m4-obstack.m4: Rewrite as a wrapper for
791 gnulib/m4/obstack.m4.
793 2003-09-04 Gary V. Vaughan <gary@gnu.org>
795 GNU M4 currently builds with a number of files adapted from
796 upstream sources. Recently the gnulib project on savannah.gnu.org
797 has pulled together a great many of these externally maintained
798 files. This delta is the beginnings of isolating those files
799 maintained in gnulib to make it easy to synchronise M4 with the
800 upstream files prior to releases.
802 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
804 (SUBDIRS): Added new gnulib subdirectory.
805 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
806 * config/stdbool.m4: Moved from here...
807 * gnulib/m4/stdbool.m4: ...to here.
808 * m4/stdbool_.h: Moved from here...
809 * gnulib/lib/stdbool_.h: ...to here.
810 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
812 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
813 code to work with new stdbool_.h location.
814 (gnulib_srcdir): New.
816 2003-09-04 Gary V. Vaughan <gary@gnu.org>
818 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
819 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
821 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
822 (EXTRA_DIST): Use it.
824 * bootstrap: CVS autoreconf leaves file droppings. Remove
825 aclocal.m4t incase autoreconf doesn't.
827 2003-08-29 Gary V. Vaughan <gary@gnu.org>
829 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
830 the other gnulib imports, renamed to m4/obstack_.h.
831 * m4/obstack.c: Updated from CVS gnulib.
832 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
833 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
834 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
835 about vpath already, and $top_srcdir upsets CVS Automake, so the
836 $top_srcdir reference was removed.
838 * m4/system-h.in: For consistency with the gnulib imports, renamed
840 * m4/Makefile (EXTRA_HEADERS): Adjust.
841 * configure.ac (AC_CONFIG_FILES): Adjust.
843 * m4/stdbool_.h: New file from gnulib for systems without their
845 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
846 * config/stdbool.m4: New file. Macros from gnulib for same.
847 * configure.ac: Use it.
849 2003-08-27 Gary V. Vaughan <gary@gnu.org>
851 * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'`
852 * config/gmp.m4: Ditto.
853 * config/gnu-obstack.m4: Ditto.
854 * config/stackovf.m4: Ditto.

915 possible or faking one with a typedef. Changed all callers.
917 2003-08-15 Gary V. Vaughan <gary@gnu.org>
919 Still cleaning up the users' module API, by taking out the stuff
920 that isn't used by any existing modules, and moving specialised
921 functions out of libm4 and into the module they are used by.
923 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
924 * m4/utility.c (m4_skip_space): ...to here the home of its only
925 use, made static and renamed to `skip_space'. Changed all
927 * m4/m4module.h (m4_expand_ranges): Removed prototype.
928 * m4/utility.c (m4_expand_ranges): Moved definition from here...
929 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
931 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
933 * modules/gnu.c (builtin_syntax): Import and use in this
934 builtin implementation.
935 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
937 * m4/macro.c (trace_flush): Except here where the macro is now
939 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
940 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
942 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
943 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
945 2003-08-14 Gary V. Vaughan <gary@gnu.org>
947 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
948 compiler based AC_CHECK_HEADER that was introduced in
950 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
951 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
952 * configure.ac: Use renamed M4_AC_LIB_GMP.
954 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
955 macro that requires arguments! This stops the shell's bad
956 substitution error at configure time.
958 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
959 variables to the testsuite shell. Set the value of USE_GMP so
960 that the gmp test will run!
961 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
963 2003-08-11 Gary V. Vaughan <gary@gnu.org>
965 Libltdl already has an excellent mechanism for accessing C symbols
966 in modules. Lets use that! Remove all the exporting cruft and
967 just use lt_dlsym in conjunction with a few conventions to
968 simplify module writers' jobs. Also removed the table address
969 caching code and otherwise simplified the module loader quite a
970 bit. To access exported symbols in other modules, first the
971 exporting module must name the symbols <modname>_LTX_<symname>,
972 and the importing module must define a function type called
973 <symname>_func. The importer then adds
974 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
975 that wishes to call out to the exported functions. Care must be
976 taken that <symname> is non-NULL in the importing module incase
977 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
978 definition was in the importers source. Study
979 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
980 m4_module_import will attempt to automatically load a module
981 required for symbol access if it is not loaded already.
983 * TODO: Removed the items fixed in this delta.
984 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
986 * m4/ltdl.h (lt_dlhandle_find): Declare it.
987 * m4/module.c (m4_module_unload): Use it.
988 * src/freeze.c (reload_frozen_state): Ditto.
989 * m4/m4module.h (m4_export): Deleted. Removed all references.
990 (M4_MODULE_IMPORT): New user convenience macro for importing
991 arbitrary symbols from other modules.
992 * m4/module.c (m4_module_import): New function to service
993 M4_MODULE_IMPORT macro.
994 (module_data): Removed. Looking up the tables on demand with
995 lt_dlsym, rather than caching their addresses here simplifies the
997 (m4_get_module_builtin_table, m4_get_module_macro_table):
998 Removed. Changed all callers.
999 (set_module_macro_table, set_module_builtin_table): Renamed to
1000 install_macro_table and install_builtin_table respectively, and
1001 simplified now that the cache is no more.
1002 * modules/gnu.c (builtin_symbols): Use this new mechanism to
1003 import m4_dump_symbols from the m4 module.
1004 (builtin_esyscmd): Likewise for m4_set_sysval and
1006 * modules/m4.c (m4_export_table): Removed. Functions are
1007 addressed with the new mechanism which doesn't need this.
1008 (m4_set_sysval): New exported accessor function to prevent
1009 problems with variable access on inferior architectures.
1010 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
1011 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
1012 that we can have some type safety.
1013 * modules/modtest.c (export_test): C level exported function for
1014 testing the new import mechanism.
1015 * modules/import.c: New file for the import end of the test.
1016 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
1017 * tests/modules.at: New test cases for intermodule symbol
1020 2003-08-07 Gary V. Vaughan <gary@gnu.org>
1022 * m4/m4module.c (m4_string): Moved from here...
1023 * m4/m4private.c (m4_string): ...to here.
1025 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
1027 2003-07-29 Gary V. Vaughan <gary@gnu.org>
1029 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
1030 already available to module writers through
1031 m4_{get,set}_nesting_limit_opt(), so moved from here...
1032 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
1033 (m4_create): Use it.
1035 2003-07-28 Gary V. Vaughan <gary@gnu.org>
1037 Aside from auditing path.c for m4module.h api obfuscation, this
1038 delta introduces the concept of private struct members in opaque
1039 data types to GNU m4: See the STYLE file for details.
1041 * TODO: Remind ourselves that a rewrite of path.c is needed.
1042 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
1044 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
1045 here and renamed. These type definitions are for internal api use
1046 only. Changed all callers.
1047 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
1049 * m4/path.c (search_path_env_init, search_path_add): ...to here
1050 and renamed. These calls were never used outside this file.
1051 Changed all callers.
1052 (dirpath): Moved functionality of this static declaration...
1053 * m4/m4private.h (struct m4): ...to this new internal only
1054 search_path field. Changed all callers.
1055 (m4__get_search_path): Added new internal api accessor.
1056 * m4/path.c (m4_search_path_info_new): Removed. Not used.
1057 (m4_include_init): Removed...
1058 * m4/m4.c (m4_create): ...because the new m4 field is now
1060 (m4_delete): Recycle search_path memory.
1061 * src/main.c (main): Don't call m4_include_init now that it's
1063 * doc/STYLE: Document convention for private fields in opaque
1066 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1068 Sometimes exporting the address of a symbol from a module isn't
1069 enough for other modules to call that symbol correctly. If
1070 custom data types are used for function parameters, they need to
1071 be known to the caller. This change introduces the concept of
1072 $(prefix)/include/modules/$(modulename).h to declare those
1073 structures. Also we move m4_dump_symbols from libm4 to the m4
1074 module to show this concept in action.
1076 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
1077 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
1078 exporting data structures from modules/m4.c.
1079 * modules/m4.c, modules/gnu.c: Include it.
1080 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
1081 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
1083 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
1085 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
1086 ...to here, with slight renaming.
1087 (m4_export_table): Prototype and add m4_dump_symbols.
1088 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
1089 definition of m4_dump_symbols.
1090 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
1091 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
1093 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1095 Create an export table in modules/m4.c in readiness for beefing up
1096 the module loader to track module exports and imports.
1098 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
1099 * m4/debug.c (m4_debug_flush_files): Moved...
1100 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
1101 * modules/gnu.c (builtin_esysval): Use it.
1102 * m4/m4module.h (m4_export): New type for declaring module symbols
1104 * modules/m4.c (m4_export_table): List symbols exported from this
1105 module for use by other modules.
1107 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1109 An experiment: There is loads of code in libm4 which should be in
1110 the m4 module, but is also used by another module. Just because
1111 some linkers won't cope with calls across dynamic runtime loaded
1112 objects I initially left the code in libm4. It will tidy the
1113 module api immensely if this code moves to the right place, I just
1114 need to remember to invent a suitable calling mechanism at some
1115 point. For now, only modules that are statically linked and
1116 preloaded will get this treatment, so the only platforms that will
1117 break are those that require all symbols to be resolved at link
1120 * TODO: Reminder that what I am doing could reduce portability
1121 unless I do something more robust later.
1122 * m4/m4module.h (m4_sysval): No longer exported from libm4.
1123 * m4/utility.c (m4_sysval): No longer declared in libm4.
1124 * modules/Makefile.am: Reformatting.
1125 * modules/m4.c (m4_sysval): Declare it at place of use.
1126 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
1128 2003-07-23 Gary V. Vaughan <gary@gnu.org>
1130 * m4/m4module.h: Reformatting and rearranging lines a bit.
1131 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
1133 (m4_call_macro, m4_expand_input): Renamed...
1134 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
1136 (m4_expansion_level, m4_process_macro): Moved...
1137 * m4/macro.c (expansion_level, process_macro): ...to here, and
1140 * m4/m4module.h (program_name): Not used by modules at all, so
1142 * src/main.c (program_name): ...to here.
1143 (print_program_name): Renamed...
1144 (print_program_name_CB): ...to conform to the STYLE guide.
1146 2003-07-23 Gary V. Vaughan <gary@gnu.org>
1148 More refactoring of the m4module.h API. Replace #defines with an
1149 enum, and move non-public functions out of the public API.
1151 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
1153 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
1154 * m4/debug.c (m4_debug, trace): Moved...
1155 * m4/m4private.h (struct m4): ...to fields of this struct.
1156 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
1158 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
1159 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
1160 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
1161 * m4/m4module.h (m4_context_field_table): Add entries for new
1162 debug_file and trace_messages fields.
1163 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
1164 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
1165 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
1166 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
1167 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
1168 (m4_is_debug_bit): New macro to simplfy checks against the debug
1170 (m4_trace_format, m4_trace_header, m4_trace_flush)
1171 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
1173 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
1174 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
1175 * m4/macro.c (trace_format, trace_header, trace_flush)
1176 (trace_prepre, trace_pre, trace_post): ...to these newly static
1177 functions, since they are only ever used from this file. Changed
1180 2003-07-17 Gary V. Vaughan <gary@gnu.org>
1182 Change the macros for checking syntax so that matching against
1183 multiple possible syntax classes can be done with a single
1184 comparison some of the time. The various classes are now bits of
1185 an int that can be checked with bitwise logic operators.
1187 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
1188 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)

1197 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
1198 Replace all calls with invocations of these...
1199 (m4_is_syntax, m4_has_syntax): ...New macros.

1201 is no longer required with new macros. Changed all callers.
1203 2003-07-15 Gary V. Vaughan <gary@gnu.org>
1205 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
1206 values are returned as part of the internal interface, so they

1209 * m4/macro.c (expand_token): Check for out of range
1210 m4_peek_input() results before looking up in the syntax table.
1211 (collect_arguments): Ditto.
1213 * NEWS: Note `$' syntax class.
1215 2003-07-08 Paul Eggert <eggert@twinsun.com> and
1216 Gary V. Vaughan <gary@gnu.org>
1218 Conform to POSIX if the POSIXLY_CORRECT environment is set.
1219 --traditional `define' now smashes all the definitions.
1221 * NEWS: Explain this.
1222 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
1223 (Extensions): Explain that extensions that are incompatible with
1224 POSIX are disabled if POSIXLY_CORRECT is set.
1225 (Incompatibilities): Remove.
1226 (Define, Other Incompat): Explain difference
1227 between GNU and POSIX behavior of define, pushdef, popdef.
1228 * m4/m4.c (m4_get_posixly_correct_opt): New undef.

1246 * doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
1247 * m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
1248 not to slow the parser down.
1249 (M4__IS_STRING): New macro to test string syntax class membership.
1250 * m4/syntax.c: Adjust docucomment.
1251 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
1252 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
1253 * m4/input.c (init_builtin_token): Comment typo.

1255 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
1256 by using the new M4__IS_STRING macro.
1257 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
1258 variable references in macro expansions.
1260 * doc/m4.texinfo (Eregexp and Regexp): Typo.
1261 (Epatsubst and Patsubst): Typo.
1264 2003-06-26 Gary V. Vaughan <gary@gnu.org>
1266 Move the global variables that pertain to syntax to a new `struct
1267 m4_syntax_table', and then add one of these to `struct m4'. The
1268 ripple effect through the code to both change formerly global
1269 references, and make sure a suitable context is available in
1270 lexical scope is disproportionately large compared to the size of
1271 the change proper. This change is a large part of decoupling
1272 syntax.c from the rest of the code that uses it.
1274 * m4/m4private.h (struct m4): Add a syntax field.
1275 * m4/m4.c (m4_create): Initialise it,
1276 (m4_delete): Recycle it.
1277 (m4_get_symtab): Remove hand coded version...
1278 (m4_get_symbol_table): ...and generate this with cpp. Changed all
1280 * m4/m4module.h (m4_context_field_table): Add an extra field so we
1281 can generate m4_get_symbol_table. Add a new row for
1282 m4_get_syntax_table.
1283 (M4SYNTAX): Syntactic sugar for module writers.
1284 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
1285 (m4_syntax_table): New home for syntax related formerly global
1287 * m4/m4private.h (struct m4_syntax_table): Define it.
1288 * m4/input.c (m4_input_init): Initialisation of these formerly
1289 global variables moved...
1290 * m4/syntax.c (m4_syntax_create): ...to here.
1291 * m4/input.c (m4_input_exit): And similarly, recycling of the
1292 memory used by those values moved...
1293 * m4/syntax.c (m4_syntax_delete): ...to here.
1294 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
1295 Moved to m4/m4private.h.
1296 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
1297 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
1298 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
1299 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
1300 objects. Changed all callers that used to directly access the
1302 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
1303 Removed and incorporated into m4_syntax_table structure.
1304 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
1305 * m4/syntax.c (m4_set_syntax): Now returns an error status,
1306 instead of requiring a `struct m4' to generate its own errors.
1307 Changed all callers.
1308 * src/main.c (main): Now that the syntax table is initialised as
1309 part of m4_create, we have to manually wipe the syntax entries if
1310 we are about to read a frozen file.
1312 2003-06-26 Gary V. Vaughan <gary@gnu.org>
1314 * doc/STYLE: Added notes on callback naming schemes.
1316 * m4/module.c (m4_set_module_macro_table)
1317 (m4_set_module_builtin_table): Declarations weren't changed when
1318 definitions were renamed on 2003-06-19.
1320 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
1321 neither used nor particularly appropriate since it exposes the
1322 internal workings of the hash module. I haven't yet decided
1323 whether to remove it entirely.
1325 2003-06-20 Gary V. Vaughan <gary@gnu.org>
1327 Two related changes, and a huge knockon effect throughout the
1328 source: Moved the option variables out of global space and into
1329 `struct m4'; made `m4_symtab' a real datatype, so that its api
1330 is not marred passing `struct m4' around just so it can decide
1331 whether to keep traced symbol names or not. Added setters and
1332 getters for the formerly global option variables, and obviously
1333 changed a vast number of functions to take a `struct m4' and use
1334 the getter funcs to find option values.
1336 * m4/utility.c (interactive, sync_output, debug_level)
1337 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
1338 (max_debug_argument_length, warning_status, nesting_limit)
1339 (discard_comments): Removed.
1340 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
1341 (debug_level, max_debug_argument_length, prefix_all_builtins)
1342 (suppress_warnings, discard_comments, interactive, sync_output):
1343 Removed from here...
1344 * m4/m4private.h (struct m4): ...and equivalent fields added to
1346 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
1347 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
1348 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
1349 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
1350 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
1351 macros for the new fields.
1352 * m4/m4module.h (m4_context_field_table)
1353 (m4_context_opt_bit_table): Helper macros used to generate
1354 prototypes, setters and getters for new option fields
1356 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
1357 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
1358 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
1359 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
1360 (m4_get_interactive_opt, m4_get_sync_output_opt)
1361 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
1362 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
1363 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
1364 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
1365 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
1366 setter and getter functions generated by cpp from
1367 m4_context_field_table and m4_context_opt_bit_table, exported as
1368 part of the module api. Changed all callers.
1369 * m4/symtab (struct m4_symtab): Used as the concrete type for
1371 (m4_symtab_create): Allocate and initialise a new struct.
1372 (m4_symtab_apply): New function that works like m4_hash_apply, but
1373 with different callbacks specific to symbol tables. Changed all
1375 (symbol_destroy, arg_destroy, arg_copy): Renamed
1376 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
1377 they have unused parameters for a reason!
1378 (dump_symbol_CB): New callback to dump the contents of a single
1380 (symtob_dump): Rewritten in terms of dump_symbol_CB.
1381 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
1382 Changed all callers.
1383 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
1384 of the contained `m4_symtab' at the `no_gnu_extensions' field.
1385 Although I'm not convinced these semantics are correct, they are
1386 at least consistent with how things were before this delta. Also
1387 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
1389 2003-06-19 Gary V. Vaughan <gary@gnu.org>
1391 Tie down the interface to libm4 some more. Make more structures
1392 opaque to modules by moving them to m4private.h, and writing
1393 setters and getters. To win back the speed penalty for doing this
1394 also wrote macroized versions that do know about structure layout
1395 in m4private.h and #include that file into modules when NDEBUG is
1396 defined at compile time. There are still some accessor macros in
1397 m4private.h that need to go, but that is not necessary to clean
1400 * m4/m4module.h (m4_symbol_type): Moved...
1401 * m4/m4private.h (m4__symbol_type): ...to here.
1402 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
1403 (m4_set_symbol_traced, m4_set_symbol_name_traced)
1404 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
1405 (m4_get_symbol_func, m4_symbol_value_create)
1406 (m4_symbol_value_delete, m4_set_symbol_value_text)
1407 (m4_set_symbol_value_func): New exported api to symbols.
1408 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
1409 and m4_is_symbol_value_func.
1410 * m4/m4module.h: Prototype these guys.
1411 * m4/module.c (m4_set_module_macro_table)
1412 (m4_set_module_builtin_table): Make these static, there is no
1413 reason to pollute the api with them.
1414 * m4/m4private.h: Reformatting.
1415 (m4_get_symtab): Only define when NDEBUG is defined.
1416 (m4_get_symbol_value, m4_get_symbol_traced)
1417 (m4_set_symbol_traced, m4_set_symbol_name_traced)
1418 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
1419 (m4_get_symbol_func, m4_symbol_value_create)
1420 (m4_symbol_value_delete, m4_set_symbol_value_text)
1421 (m4_set_symbol_value_func): Macro implementations of the new
1422 functions when NDEBUG is defined.
1423 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
1424 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
1425 Superceded by the above. All callers changed.
1426 (M4ARG): Removed. This is no longer different to the
1427 m4/m4module.h definition.
1428 * modules/gnu.c, modules/m4.c: Only include m4private.h when
1429 NDEBUG is defined. That way we exercise the same (albeit slower)
1430 api that external modules must use.
1432 2003-06-18 Gary V. Vaughan <gary@gnu.org>
1434 Renamed some of the types and their accessors to make more sense.
1435 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
1436 has a stack of SYMBOL_VALUEs.
1438 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
1439 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
1440 m4_get_symbol_value_type, m4_get_symbol_value_text,
1441 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
1442 Changed all callers.
1443 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
1444 (m4_get_token_type): Renamed
1445 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
1446 to the internal api.
1447 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
1449 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
1450 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
1451 (m4__token_type): Moved here from m4module.h.
1452 (m4__next_token): Renamed from m4_next_token.
1453 * m4/symtab.c: Removed some of the parameterised macro support
1454 functions for modularisation later.
1455 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
1456 m4_hash_dup to perform a true deep copy of the SRC.
1457 (arg_copy): Callback for m4_symbol_value_copy.
1458 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
1459 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
1460 m4_get_symbol_value_func. Changed all callers.
1462 2003-06-18 Gary V. Vaughan <gary@gnu.org>
1464 Tidy up style of hash.[ch] in accordance with doc/STYLE.
1466 * m4/hash.c: Internal symbol renaming and formatting.
1467 (m4_hash_dup): New function to facilitate deep copies of hash
1469 (m4_hash_apply_func): Returns a void* now, which is a richer type
1470 for returning exceptions (NULL means keep going).
1471 (m4_hash_apply): Ditto.
1472 * m4/hash.h: Declare exported symbols with an explicit extern.
1475 2003-06-17 Gary V. Vaughan <gary@gnu.org>
1477 Still refactoring furiously. This delta represents a change in
1478 semantics to symtab.c. Instead of building temporary m4_tokens
1479 in the caller, and copying fields in the methods, we now create
1480 the actual m4_token for hashing in the caller so the methods just
1481 slot them in directly. Also, this means that we don't lookup a
1482 symbol and get back an allocated but VOID token to copy fields
1483 into, we create the token we want to push and pass that to
1484 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
1485 a few other small changes to stop knowledge of the implementation
1486 of symtab.c leaking out into other files.
1488 * m4/macro.c (expand_argument): Comment typo corrected.
1489 * m4/symtab.c (symtab_fetch): New function to fetch the address of
1491 (m4_symbol_pushdef): Take an extra value parameter and use this
1492 directly as the new top of the value stack. All callers changed
1493 to build a token and pass responsibility for memory in, rather
1494 than copying as we used to.
1495 (m4_symbol_define): Also use the new value parameter directly as a
1496 replacement for the top of the value stack. All callers changed
1497 to build a token as above.
1498 (m4_set_symbol_traced): New function to set the traced bit on the
1499 named symbol, creating it if necessary.
1500 (symbol_popval): The guts of the old m4_symbol_popdef.
1501 (m4_symbol_popdef): Use it.
1502 * m4/builtin.c (m4_symbol_set_token): Removed,
1503 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
1505 * m4/module.c (m4_set_module_builtin_table)
1506 (m4_set_module_macro_table): ...with these more orthogonal
1508 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
1509 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
1511 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
1512 (m4_arg_signature_parse): Moved...
1513 * m4/symtab.c: ...to here.
1514 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
1515 screw something up. Moved...
1516 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
1517 actually does a proper deep copy of source to dest.
1519 2003-06-16 Gary V. Vaughan <gary@gnu.org>
1521 Further refactoring to stabilise the module API. Renaming some
1522 functions for orthogonality, and judicious definition migration to
1523 move things out of the set of exported symbols.
1525 * doc/STYLE: New file. Notes on coding style.
1526 * m4/m4module.c: Updated bitrotted docucomment at the top of the
1528 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
1529 m4_get_module_name, m4_get_module_builtin_table,
1530 m4_get_module_macro_table which are verb phrases. Changed all
1532 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
1534 * m4/module.c (m4_set_module_builtin_table)
1535 (m4_set_module_macro_table): ...here, and renamed. Changed all
1537 * m4/m4module.c (m4_module_data): This...
1538 * m4/m4private.c (struct m4_module_data): ...and this...
1539 * m4/module.c (module_data) ...consolidated here and no longer
1540 exported. Changed all callers.
1542 2003-06-16 Gary V. Vaughan <gary@gnu.org>
1544 Begin work on lifting the curse of the global variables. To start
1545 with create a `struct m4' context container, and replace
1546 `m4__symtab' with `context->symtab' throughout. This means
1547 initialising a context container in main, and adjusting many
1548 functions between main and the module entry points so that the
1549 container gets passed through. It would have been nice to
1550 defer this until after 1.5, but it has a major effect on the
1551 user's module writing ABI, so it needs to be addressed now - at
1552 least in the areas that impact the ABI. An interrelated change
1553 in the symtab API removes the dependency on a global symbol table,
1554 and instead focuses on a passed table (from the context
1557 * TODO: Reminders for finishing context functionality.
1558 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
1559 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
1560 global variables and eventually allow m4 to be reentrant.
1561 * m4/m4private.h (m4): Define the new structure here...
1562 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
1563 don't carry the overhead of a function call.
1564 * m4/m4module.h: Prototype extern functions from m4/m4.c.
1565 (m4): Declare type for new struct m4 objects.
1566 (M4SYMTAB): User macro to ease finding the symbol table for the
1567 current context for module developers.
1568 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
1570 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
1571 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
1572 (m4_call_macro, m4_dump_symbols, m4_expand_input)
1573 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
1574 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
1575 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
1576 m4* context parameter. Changed definitions and all callers.
1577 (m4_symtab): Alias for m4_hash to decouple the
1578 m4_symtab api from m4_hash.
1579 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
1581 (m4_symtab_create): New function to return an initialised
1583 (m4_symtab_delete): New function to delete an m4_symtab's memory.
1584 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
1585 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
1586 instead of simply using the global m4__symtab. Changed
1587 definitions and all callers.
1588 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
1589 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
1590 * src/main.c (main): Create a context and use that instead of the
1591 former global m4__symtab.
1593 2003-06-13 Gary V. Vaughan <gary@gnu.org>
1595 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
1596 to the callback. Callbacks should not need to hardcode the
1597 hashtable they are working from, nor should we have to waste the
1598 userdata parameter to pass the table in.
1599 * m4/hash.h (m4_hash_apply_func): Require the initial table
1601 * m4/symtab.c (symtab_destroy): Use the passed table instead
1602 of hardcoding m4__symtab.
1603 (m4_symbol_popdef): Don't use the userdata parameter to pass the
1604 table to arg_destroy.
1605 (arg_destroy): Use the hash parameter, ignore userdata.
1606 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
1608 (traceon, traceoff): Call set_trace with the extra initial
1611 2003-06-13 Gary V. Vaughan <gary@gnu.org>
1613 More refactoring to stabilise the module api, this time for
1614 symtab.c. Additionally, start to pay attention to function names
1615 that don't contain a verb like they should.
1617 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
1618 wrapper for m4_hash_apply to decouple the symtab module from the
1620 (m4_symbol_builtin, m4_symbol_macro): Renamed to
1621 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
1623 (m4_symbol_delete): Create a macro version to save a function
1625 (m4_token_t, m4_data_t): These violate the POSIX reserved
1626 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
1628 (m4_token_type): Renamed to m4_token_get_type.
1629 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
1630 (m4_symtab_exit): Removed from the exported module
1632 * m4/m4private.h (m4__symtab, m4__symtab_init)
1633 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
1634 renamed and added to the internal api. Changed all callers.
1635 (m4_symtab_apply): A faster macro version of the function for
1636 users of the internal api.
1637 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
1638 symbol_destroy and arg_destroy.
1639 (symtab_debug): Added a prototype.
1640 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
1641 so that callers in this file get the faster macro versions from
1644 2003-06-12 Gary V. Vaughan <gary@gnu.org>
1646 Refactoring modules to rationalise the API into an external
1647 documented (eventually!) API for use by modules in the `m4_'
1648 namespace declared in m4/m4module.h, an internal API between the
1649 source files we ship (including our shipped modules) in the `m4__'
1650 namespace declared in m4/m4private.h and making the rest as
1651 cohesive as possible with liberal use of the `static' keyword.
1652 This change represents an audit to m4/module.c along these
1655 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
1656 Removed. No longer used.
1657 (m4_module_close): Removed prototypes.
1658 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
1659 from the exported module api...
1660 * m4/m4private.h (m4__module_init, m4__module_open)
1661 (m4__module_exit): ...and renamed and added to the internal api.
1662 Changed all callers.
1663 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
1664 Centralised definitions after renaming...
1665 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
1666 (M4_FINISH_SYMBOL): ...and removing from here.
1667 (m4_module_dlerror, m4_module_remove, m4_module_close)
1668 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
1669 module_remove, module_close and caller_id.
1670 (MODULE_SELF_NAME): New macro to make reporting self errors
1672 (m4_module_load, module_close, module_remove): Use it.
1673 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
1675 * src/main.c (main): Use it.
1677 2003-06-12 Gary V. Vaughan <gary@gnu.org>
1679 * README: Remove references to --enable-changeword, which has been
1680 removed from the code.
1682 2003-06-11 Gary V. Vaughan <gary@gnu.org>
1684 Getting rid of the annoying bug with configure --enable-debug,
1685 which spewed -e: command not found errors. This was an interaction
1686 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
1687 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
1688 branch-1-5) to get the full fix.
1690 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
1691 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
1692 and then use the probed value of $SED.
1693 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
1694 this, it messes up the AC_REQUIRE stack.
1696 2003-06-10 Gary V. Vaughan <gary@gnu.org>
1698 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
1699 the destroy callback.
1700 (m4_arg_destroy): Use the hash address to free the hash node key
1703 2003-06-06 Gary V. Vaughan <gary@gnu.org>
1705 First cut at formal parameters in macros.
1707 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
1708 * m4/xstrzdup.c: New file.
1709 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
1710 associative array of parameter names to details.
1711 (m4_symbol_token): Capture macro names with parameter lists.
1712 (m4_arg_signature_parse): And build an associative array to hang
1713 from the symbol structure to map names to details.
1714 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
1715 m4_hash_resize idiom. Now that we potentially add a little hash
1716 table to many of the entries in the symbol table, added an extra
1717 arg to set the initial size. Changed all callers.
1718 (m4_hash_apply): New function that is basically a generalised
1720 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
1721 all callers to call m4_hash_apply instead.
1722 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
1723 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
1724 m4_arg_signature association that might be attached to the symbol,
1725 * m4/hash.h (m4_hash_apply_func): Replacement type for...
1726 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
1727 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
1729 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
1730 (M4_IS_IDENT): Detect characters that can be safely used in
1732 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
1733 * m4/macro.c: Corrected grammar in some comments. Use `token'
1734 rather than `td' for m4_token variables.
1735 (m4_process_macro): If we find a dollar followed by some
1736 M4_IS_IDENT characters, replace that with the contents of the argv
1737 entry with offset stored in the m4_token_arg associated with the
1738 collected identifier.
1740 2003-06-05 Gary V. Vaughan <gary@gnu.org>
1742 Begin preparations for supporting formal parameters in m4 macros.
1744 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
1745 the details of a formal parameter.
1746 (m4_token): Add an arg_signature member to hold a hash table for
1747 looking up formal parameters.
1748 * m4/input.c: Update more bitrotted comments.
1749 (m4_push_builtin): Initialise arg_signature member.
1750 (init_builtin_token): Copy arg_signature member.
1751 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
1752 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
1754 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
1755 (m4_macro_pushdef, m4_macro_define): ...these, And...
1756 (m4_symbol_token): ...wrapped around this new function, which
1757 vastly simplifies the arguments required by the functions it
1759 Changed all callers.
1761 2003-06-05 Gary V. Vaughan <gary@gnu.org>
1763 * m4/macro.c: Format changes.
1765 2003-06-04 Gary V. Vaughan <gary@gnu.org>
1767 * m4/input.c: Updated various bitrotted comments.
1768 (m4_push_builtin): Just pass the whole m4_token, rather than
1769 extracting all the fields in the caller. This also allows us to
1770 check the token type for consistency.
1771 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
1772 Renamed to builtin_funcs, builtin_peek, builtin_read,
1773 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
1774 the code. Changed all callers.
1775 (struct input_block): Similarly renamed u_m member to u_b, and
1776 changed all callers.
1777 (m4_next_token): Use bzero to initialise the data fields.
1778 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
1780 2003-05-29 Gary V. Vaughan <gary@gnu.org>
1782 These changes were necessary to get m4 to build on my iBook
1783 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
1784 (GCC) 3.1 20020420 (prerelease)":
1786 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
1787 inclusion of module loader headers.
1788 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
1789 * m4/Makefile.am: Ditto.
1790 (libm4_la_LIBADD): Added $(LTLIBINTL).
1791 * m4/utility.c (program_name): Removed declaration in favour of
1792 the one already in error.c!
1793 * m4/m4module.h (program_name): Define to program_invocation_name
1794 when using GNU C library. Use an explicit extern declaration.
1795 (interactive, sync_output, debug_level, hash_table_size)
1796 (no_gnu_extensions, prefix_all_builtins, max_debug_argument_length)
1797 (suppress_warnings, warning_status, nesting_limit, discard_comments)
1798 (lquote, rquote, bcomm, ecomm, m4_bad_argc, m4_skip_space)
1799 (m4_numeric_arg, m4_shipout_int, m4_shipout_string, m4_dump_args)
1800 (m4_debug, m4_debug_init, m4_debug_exit, m4_debug_decode)
1801 (m4_debug_flush_files, m4_debug_set_output, m4_debug_message_prefix)

1803 (m4_expansion_level, m4_expand_ranges, m4_expand_input)
1804 (m4_call_macro, m4_process_macro, m4_syntax_table, m4_current_file)
1805 (m4_current_line, m4_current_diversion, m4_output_current_line):
1806 Don't rely on default, use an explicit extern.
1807 * m4/error.h (error, error_at_line, error_print_progname)
1808 (error_message_count, error_one_per_line): Ditto.
1809 * m4/ltdl.c: Update from CVS libtool.
1811 * commit: Update from CVS cvs-utils.
1813 2002-11-04 Akim Demaille <akim@epita.fr>
1815 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
1817 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
1819 2002-11-04 Akim Demaille <akim@epita.fr>
1821 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
1823 2002-11-04 Akim Demaille <akim@epita.fr>
1825 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
1826 used as `external', and Libtool 1.4.3.
1828 (LTLIBOBJS): Don't play with it.
1830 * Makefile.am (SUBDIRS): Remove intl.
1831 (ACLOCAL_AMFLAGS): Add -I config.
1832 (EXTRA_DIST): Add config/config.rpath.
1835 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
1837 2002-05-29 Gary V. Vaughan <gary@gnu.org>
1839 Preparations for refactoring syntax tables to allow reverse
1840 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
1841 speed of normal lookups in an array of unsigned short.
1843 * m4/input.c (single_quotes, single_comments, use_macro_escape):
1845 * m4/m4private.h (m4__single_quotes, m4__single_comments,
1846 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
1847 is for internal symbols which unavoidably pollute the global
1848 namespace, but are not published APIs.
1849 Adjusted all callers.
1850 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
1851 m4_set_comment, m4_set_syntax, set_syntax_internal,
1852 unset_syntax_attribute): Moved from this file...
1853 * m4/syntax.c: New. ...to this file.
1854 Also added an m4_syntax_exit stub for orthogonality.
1855 * src/main.c (main): Use it.
1856 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
1857 * m4/m4module.h: Reformatting. New prototypes.
1859 2002-05-29 Gary V. Vaughan <gary@gnu.org>
1861 * bootstrap (aclocal_apiversion): The aclocal apiversion is
1862 distinct from the automake release number (in that the apiversion
1863 apparently has no micro-version-component).
1864 (aclocal_apilibdir): Use it.
1866 2002-05-28 Gary V. Vaughan <gary@gnu.org>
1868 * m4/hash.c (m4_hash_resize): New function.
1869 * m4/hash.h: Add prototype.
1870 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
1871 benchmarking to find a good value for, say, autoconf. This is
1872 already a little quicker than before for me.
1874 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
1875 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
1877 * m4/hash.h: Adjust prototypes.
1879 2002-01-22 Akim Demaille <akim@epita.fr>
1881 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
1883 * tests/Makefile.am (package.m4): New.
1884 * tests/atlocal.in: Adjust to CVS Autotest.
1885 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
1886 * configure.ac: LIBOBJ is a forbidden string.
1887 Simplify AM_INIT_AUTOMAKE invocation.
1888 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
1891 2001-10-19 Akim Demaille <akim@epita.fr>
1893 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
1895 2001-10-19 Akim Demaille <akim@epita.fr>
1897 * m4/input.c (m4_next_token): Display where was opened what is
1900 2001-10-19 Akim Demaille <akim@epita.fr>
1902 * m4/macro.c (expand_argument): Display where was opened what is
1905 2001-10-18 Akim Demaille <akim@epita.fr>
1907 * m4/input.c, modules/m4.c: Formatting changes.
1909 2001-10-17 Gary V. Vaughan <gary@gnu.org>
1911 * bootstrap: s/configure.in/configure.ac/
1913 2001-10-16 Gary V. Vaughan <gary@gnu.org>
1915 * m4/symtab.c (m4_symbol_destroy): This function calls
1916 m4_symbol_popdef, which recycles a symbols memory when the last
1917 definition is popped. Since we were passing the address of the
1918 symbol name found in the symbol table, and it was being removed
1919 partway through m4_symbol_destroy() we were referencing freed
1920 memory for the balance of the function. Now we take a copy of the
1921 symbol name tring and use that as a key into the symbol
1922 table... that way if the original symbol name is freed, the copy
1925 2001-10-13 Akim Demaille <akim@epita.fr>
1927 * m4/ltdl.c: Update.
1929 2001-10-13 Akim Demaille <akim@epita.fr>
1931 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
1932 Don't gettextize internal error messages.
1934 2001-10-13 Akim Demaille <akim@epita.fr>
1936 * tests/macros.at (Arity and defn): New failing test.
1937 (Arity, defn, and freeze): New.
1939 Fix `Arity and defn'.
1941 * m4/input.c (m4_push_macro): Don't forget the arity.
1942 * modules/m4.c (defn): Likewise.
1944 2001-10-13 Akim Demaille <akim@epita.fr>
1946 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
1948 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
1949 (Propagation of traceon, Propagation of --trace): this new file.
1951 2001-10-13 Akim Demaille <akim@epita.fr>
1953 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
1954 interface instead of (name, argc...).
1955 Upon failure, specify which argument was guilty.
1958 2001-10-13 Akim Demaille <akim@epita.fr>
1960 * modules/evalparse.c: Save translators' time: don't translate
1961 internal error messages.
1962 (m4_evaluate): Simplify/normalize error messages.
1963 * doc/m4.texinfo (Eval): Adjust.
1965 2001-10-13 Akim Demaille <akim@epita.fr>
1967 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
1968 where no checking is needed.
1969 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
1970 interface instead of (name, argc...).
1972 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
1975 2001-10-13 Akim Demaille <akim@epita.fr>
1977 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
1978 exclude the builtin name from the count.
1979 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
1980 calling ifelse with a single argument is valid.
1981 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
1982 with 1 and 2 args, mostly to strengthen the test suite.
1984 2001-10-13 Akim Demaille <akim@epita.fr>
1986 * m4/output.c (m4_make_diversion, m4_insert_file)
1987 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
1989 2001-10-12 Gary V. Vaughan <gary@gnu.org>
1991 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
1992 since we call these things builtins in the rest of the code!
1994 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
1996 2001-10-12 Gary V. Vaughan <gary@gnu.org>
1998 Rather than forcing each builtin definition to manage its own
1999 argument range checking, tabulate the maxima and minima for all
2000 builtins in each module. This forces us to consider what the
2001 valid ranges for each builtin should be, and moves the checking
2002 code out of each builtin implementation and into the builtin
2003 caller infrastructure.
2005 * m4/m4module.h (struct m4_builtin): Add argument minima and
2007 * m4/m4private.h (struct m4_token): Reflect them here too.
2008 * m4/input.c (struct input_block): ...and here.
2009 (m4_token_copy): New function for token copying.
2010 (init_macro_token): Copy them from a token to the input stack.
2011 (m4_next_token): Don't forget to initialise them for text
2013 * m4/macro.c (expand_argument): Use m4_token_copy, and also
2014 check argument counts before calling the builtin handler.
2015 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
2016 (m4_symbol_macro): Likewise.
2017 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
2018 parameters. Updated all callers.
2019 (m4_builtin_define): Ditto.
2020 (m4_macro_pushdef, m4_macro_define): Ditto.
2021 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
2022 * modules/evalparse.c: Declare argument counts for defined
2023 builtins and remove explicit calls to m4_bad_argc().
2024 * modules/gnu.c: Ditto.
2025 * modules/load.c: Ditto.
2026 * modules/m4.c: Ditto.
2027 * modules/modtest.c: Ditto.
2028 * modules/mpeval.c: Ditto.
2029 * modules/perl.c: Ditto.
2030 * modules/shadow.c: Ditto.
2031 * modules/stdlib.c: Ditto.
2032 * modules/time.c: Ditto.
2035 2001-10-10 Gary V. Vaughan <gary@gnu.org>
2037 The trace semantics now attach the trace bit to a symbol name.
2038 For as long as a traceon(`foo') is active, calls to foo will be
2039 traced regardless of intervening undefines or module unloads.
2040 Fixed the flag propogation issues differently to the fixes
2041 reverted with the last attempt at nailing down trace:
2043 * m4/m4private.h: This file is not visible outside of the m4
2044 source tree, so I removed all the `M4_' and `m4_' prefixes to save
2045 on typing. Updated all clients.
2046 (m4_token): New typedef contains the fields that need to be passed
2047 around with the low level tokeniser.
2048 (m4_token_data): Removed.
2049 (m4_symbol): Now contains the traced flag again.
2050 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
2051 the trace bit set. This change is contained entirely within this
2052 module and doesn't leak out into the callers. Updated all
2054 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
2055 new fields in m4_token. Updated all clients.
2056 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
2057 that `groks_macro_args' and `blind_if_no_args' flags are retained
2058 when defn() results are passed around in m4 code. Updated all
2060 (m4_builtin_define): Ditto.
2061 (m4_macro_pushdef, m4_macro_define): Ditto.
2062 * m4/input.c (struct input_block): Add a flags field to facilitate
2064 (m4_push_macro): ...use it.
2065 (init_macro_token): Retrieve it.
2066 (m4_next_token): Initialise it.
2067 * m4/macro.c (expand_argument): Copy it.
2068 * m4/m4module.h: Adjust.
2069 * tests/builtins.at: Adjust the expected output of the trace
2070 tests to reflect the change in semantics.
2071 * tests/modules.at (modules: trace): Check that unloading a
2072 module which supplies a traced symbol definition doesn't lose te
2075 2001-10-07 Gary V. Vaughan <gary@gnu.org>
2077 * modules/gnu.c (m4_macro_table): Display the timetamp when
2078 expanding __m4_version__.
2080 * configure.ac (--with-modules): Forgot a comma in the
2081 AC_HELP_STRING parameter list.
2083 2001-10-05 Gary V. Vaughan <gary@gnu.org>
2085 * bootstrap: Remove aclocal.m4t when it is no longer required.
2087 2001-10-05 Akim Demaille <akim@epita.fr>
2089 * tests/Makefile.am: Adjust for gnuprog2.
2090 * tests/m4.in: There can be a leading path.
2091 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
2092 * tests/testsuite.at: Adjust to the most recent Autotest.
2093 (AT_CHECK_M4_FILTER): Fix and rename as...
2095 * tests/others.at: Use it.
2097 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
2098 variable in shell scripts, one uses `$'...
2100 2001-10-04 Gary V. Vaughan <gary@gnu.org>
2102 * configure.ac: `rm -f $m4_getopt_h' was lost.
2104 2001-10-04 Gary V. Vaughan <gary@gnu.org>
2106 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
2107 time. Define it for config.h in order to...
2108 * src/main.c (main): ...display the timestamp for --version.
2110 2001-10-04 Akim Demaille <akim@epita.fr>
2112 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
2113 previous builtins `regexp' and `patsubst'.
2114 (regexp, patsubst): Use them.
2115 (eregexp, epatsubst): New builtins.
2116 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
2117 (Epatsubst and Patsubst, Eregexp and Regexp): these.
2118 (Extensions): More info on REs.
2120 2001-10-04 Akim Demaille <akim@epita.fr>
2122 * modules/modtest.c (init_handler): Consistently output to stderr.
2123 (finish_handler): New.
2124 (test): The `if' is an `assert'.
2125 * tests/modules.at: Adjust.
2127 2001-10-04 Akim Demaille <akim@epita.fr>
2129 * m4/utility.c (m4_bad_argc): Detail the mismatches.
2131 2001-10-01 Akim Demaille <akim@epita.fr>
2133 * tests/generate.awk: Tag the tests with `documentation'.
2134 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
2135 Use the make the existing modtest tests more uniform, and complete
2136 the set of possibilities.
2138 2001-10-01 Akim Demaille <akim@epita.fr>
2140 * config/gmp.m4: Consult the user before using GMP: use
2142 * configure.ac: Adjust.
2143 * modules/gmp.c: No protection needed as the module is not built
2146 2001-10-01 Akim Demaille <akim@epita.fr>
2148 * tests/generate.awk: Remove debugging code.
2149 (fatal): Specify the current location.
2151 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
2152 * modules/gnu.c, modules/m4.c: Use M4ARG.
2154 2001-10-01 Akim Demaille <akim@epita.fr>
2156 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
2157 (m4_regexp_compile): New.
2158 (regexp, patsubst): Use it.
2160 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2162 Reinstate the memory handling improvements from the patch I just
2163 reverted. Relevant ChangeLog entries repeated here:
2165 * m4/module.c (m4_module_remove): New function that holds the core
2166 of the old m4_module_unload.
2167 (m4_module_unload): Use it.
2168 (m4_module_unload_all): When we know the modules will never be
2169 used again (i.e. on exit), free up as much module memory as
2170 possible. There are still some artifacts from resident modules
2171 living inside ltdl.c, but everything else is freed.
2172 * m4/debug.c (m4_debug_exit): Free memory allocated in
2174 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
2175 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
2176 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
2177 * m4/m4module.h: Updated prototypes.
2178 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
2179 * m4/hash.h: Updated prototypes.
2180 * src/main.c (main): Use all these new functions to clean up as
2181 much memory as possible before exit.
2183 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2185 Reverted my large patch for removing the old m4_symbol
2186 structure on 2001-09-20. We are still not happy about the way
2187 trace works in conjunction with defn and undefine, and leaving
2188 the reverted patch active prevents us from moving the traced
2189 bit from the definition back to the symbol.
2191 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2193 * configure.in: Moved to...
2194 * configure.ac: ...here. Added a libtool like timestamped
2195 banner, and tidied up the libltdl cruft.
2196 * config/mkstamp: Script to extract a timestamp from ChangeLog.
2197 * modules/Makefile.am (INCLTDL): Removed. This is required
2198 only when libltdl is configured in a subdirectory.
2199 * src/Makefile.am: Ditto.
2200 (LIBADD_DL): No need to add this again, libtool already knows
2201 that libm4.la depends on it.
2202 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
2205 * TODO: stackovf.c is basically broken.

2208 2001-09-28 Akim Demaille <akim@epita.fr>
2210 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
2212 2001-09-27 Akim Demaille <akim@epita.fr>
2214 * tests/m4.in: Don't use short options.
2215 Simplify the stderr signature normalization.
2217 2001-09-27 Akim Demaille <akim@epita.fr>
2219 tests/m4 shall be position independent.
2223 * tests/testsuite.at: No args to AT_INIT.
2224 * configure.in, tests/Makefile.am: Adjust.
2226 2001-09-22 Akim Demaille <akim@epita.fr>
2228 Autotest has changed again.
2230 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
2231 (package.m4): Remove.
2232 * configure.in: Adjust to LIBADD_GMP.
2234 2001-09-21 Gary V. Vaughan <gary@gnu.org>
2236 * config/gmp.m4 (AC_ARG_WITH): Removed.
2237 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
2238 (AC_LIB_GMP): When performing a test compile against libgmp,
2239 include the header gmp.h if possible, and link against -lgmp. If
2240 they both work define USE_GMP.
2241 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
2242 (mpeval_LTX_init_func): Complain on load that there was no libgmp
2245 2001-09-20 Gary V. Vaughan <gary@gnu.org>
2247 * m4/evalparse.c: Moved to...
2248 * modules/evalparse.c: ...here. This code is shared between
2249 modules/mpeval.c and modules/m4.c, so there is no need to pollute
2250 the libm4 API with its details. Moderately rewritten to interface
2251 into its clients more simply.
2252 * m4/eval.c: Deleted. Migrated functionality to...
2253 * modules/m4.c: ...here.
2254 (builtin_eval): Implemented in terms of the new interface style.
2255 * modules/mpeval.c (builtin_mpeval): Ditto.
2256 * m4/m4module.h: Removed references to the former m4/eval.c.
2257 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
2258 (EXTRA_libm4_la_SOURCES): Deleted.
2259 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
2260 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
2262 2001-09-20 Akim Demaille <akim@epita.fr>
2264 * config/gmp.m4 (AM_WITH_GMP): Rename as...
2266 By default, use gmp.
2268 * configure.in: Adjust.
2269 Use Automake conditionals for USE_GMP.
2270 Always compute sizeof (long long int).
2271 This was a bug BTW, as `eval' (not `mpeval') depends on it:
2272 before, it was used _only_ if mpeval was not activated.
2273 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
2274 (mpeval_la_LIBADD): New macros.
2275 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
2277 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
2278 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
2281 2001-09-20 Akim Demaille <akim@epita.fr>
2283 * tests/Makefile.am (package.m4): New.
2284 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
2286 2001-09-20 Gary V. Vaughan <gary@gnu.org>
2288 More cleanup. After the last patch, m4_symbol holds nothing but
2289 the head of a chain of m4_token_data. So I have removed the old
2290 m4_symbol, so that m4_token_data chains are stored directly in the
2291 value cell of a hash table node. But there's more... m4_symbol
2292 was a more natural name for the symbol value cell, and now that it
2293 is gone I have renamed the former m4_token_data structure to
2294 m4_symbol. This change turned out to be a pig to get right, since
2295 the original code didn't need to modify the value cell itself,
2296 since changing the chain happened inside the m4_symbol that used
2297 to be returned -- I had to pass the address of the value cell
2298 across various function calls, incase the head value changed. I
2299 also tightened up the memory management to help me find a nasty
2300 memory corruption bug that took me all night to track down...
2302 * m4/m4private.h (struct m4_symbol): Removed.
2303 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
2305 * m4/hash.c (m4_hash_iterator_value): Return the address of the
2306 value cell. Updated all callers.
2307 * m4/symtab.c: Took advantage of the simplification in the data
2308 structures to rewrite a lot of this file more simply. There is
2309 still some room for optimisation here, but we should tackle that
2310 systematically closer to the release.
2312 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
2313 revealed. This version is ahead of CVS libtool until I get chance
2314 to flush my changes.
2315 * m4/module.c (m4_module_remove): New function that holds the core
2316 of the old m4_module_unload.
2317 (m4_module_unload): Use it.
2318 (m4_module_unload_all): When we know the modules will never be
2319 used again (i.e. on exit), free up as much module memory as
2320 possible. There are still some artifacts from resident modules
2321 living inside ltdl.c, but everything else is freed.
2322 * m4/debug.c (m4_debug_exit): Free memory allocated in
2324 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
2325 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
2326 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
2327 * m4/m4module.h: Updated prototypes.
2328 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
2329 * m4/hash.h: Updated prototypes.
2330 * src/main.c (main): Use all these new functions to clean up as
2331 much memory as possible before exit.
2333 2001-09-18 Gary V. Vaughan <gary@gnu.org>
2335 The `traced' flag needs to be attached to the definition of a
2336 symbol rather than the current symbol containing the definition.
2337 Implementing this showed up some long standing post 1.4 bugs in
2338 flag propogation which I also fixed.
2340 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
2341 (struct m4_token_data): And add it back in here.
2342 * m4/input.c (init_macro_token): Propogate the traced flag
2344 * m4/macro.c (expand_argument): Ditto.
2345 * tests/builtins.at (trace2, trace3): New tests based on Akim's
2348 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2350 * m4/m4private.h (struct m4_token_data): Simplified by removing
2351 the redundant `traced' flag, and one level of structure nesting.
2352 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
2353 * m4/input.c (init_macro_token): No need to initialise removed
2355 * m4/macro.c (expand_argument): No need to copy it either.
2356 * m4/utility.c (m4_token_data_func_traced): Or provide an access
2359 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
2360 dependant on multiple symbols with the same key, so preserving
2361 relative symbol order in each bucket during resizing is no longer
2362 required. The resize function is considerably faster as a result.
2364 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
2365 s/m4_symbol_insert/m4_symbol_define/g;
2366 s/m4_builtin_insert/m4_builtin_define/g;
2367 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
2369 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2371 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
2372 commits, the m4_lookup_symbol dispatch function is split into
2373 specialised functions that must be called directly.
2375 * m4/m4module.h (m4_symbol_lookup_t): Removed.
2376 * m4/symtab.c (m4_lookup_symbol): Removed.
2377 (m4_symbol_builtin, m4_symbol_macro): New functions.
2378 * m4/builtin.c (m4_builtin_define): Split into...
2379 (m4_builtin_pushdef, m4_builtin_insert): ...these.
2380 (m4_macro_define): Split into...
2381 (m4_macro_pushdef, m4_macro_insert): ...these.
2382 * src/main.c (main): Set command line macros from `-D' parameters
2383 using `m4_macro_define'.
2385 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2387 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
2388 this from m4_remove_table_reference_symbols().
2389 * m4/m4module.h, m4/module.c: Updated all references.
2391 2001-09-07 Akim Demaille <akim@epita.fr>
2393 * modules/stdlib.c, modules/times.c: Misc cleanups.
2395 2001-09-07 Akim Demaille <akim@epita.fr>
2397 * configure.in: We now need Autoconf 2.52e.
2398 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
2399 and `M4_SYMBOL_DELETE'.
2400 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
2401 * src/main.c (main): Adjust.
2403 2001-09-06 Gary V. Vaughan <gary@gnu.org>
2405 Fix the obstack.h problem once and for all! At configure time we
2406 can test for a system supplied obstack.h: depending on the
2407 result, we now generate system.h with an #include of the correct
2408 header. As a bonus, I've also added a --with-included-obstack,
2409 incase the user doesn't like the system obstack for some
2410 reason... and also we can test the shipped obstack on a system
2411 that has oe of its own. We also now need to be careful to add
2412 build directories to the include search path, since the generated
2413 system.h will be in the build tree.
2415 * configure.in (AC_CONFIG_FILES): Generate system.h from
2417 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
2418 include the system obstack header or the copy shipped with M4.
2419 Allow the user to override configure and force the build to use
2420 the shipped version.
2421 * m4/system-h.in: New file, template for...
2422 * m4/system.h: ...this. Now deleted.
2423 * m4/m4module.h: Include system.h before everything else.
2424 * src/freeze.c: Ditto.
2425 * m4/Makefile.am (dist-hook): Remove generated system.h.
2426 (INCLUDES): Check builddir for generated headers before checking
2428 * modules/Makefile.am (INCLUDES): Ditto.
2429 * src/Makefile.am (INCLUDES): Ditto.
2431 2001-09-05 Gary V. Vaughan <gary@gnu.org>
2433 * TODO: Remove the items that have been addressed already.
2435 2001-09-05 Akim Demaille <akim@epita.fr>
2437 * src/main.c (main): Standardize --version.
2439 2001-09-05 Akim Demaille <akim@epita.fr>
2441 * modules/format.c (format): Have a bigger `str'.
2443 2001-09-05 Akim Demaille <akim@epita.fr>
2445 Rationalize warnings, reporting the macro name as if it were a
2446 program name, and assertions.
2448 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
2450 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
2452 Use assert for internal errors.
2453 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
2455 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
2457 * tests/builtins.at (pushpop): Adjust.
2459 2001-09-05 Akim Demaille <akim@epita.fr>
2461 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
2464 2001-09-05 Akim Demaille <akim@epita.fr>
2466 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
2467 * m4/macro.c, m4/symtab.c: Adjust.
2469 2001-09-05 Akim Demaille <akim@epita.fr>
2471 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
2472 (m4_symbol_pop, m4_symbol_del): this.
2473 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
2474 (m4_symbol_popdef, m4_symbol_delete): New.
2475 (m4_lookup_symbol): Adjust.
2476 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
2478 2001-09-05 Akim Demaille <akim@epita.fr>
2480 * m4/m4module.h (m4_symbol_lookup): Rename as...
2481 (m4_symbol_lookup_t): this.
2483 2001-09-05 Akim Demaille <akim@epita.fr>
2485 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
2487 * m4/symtab.c (m4_lookup_symbol): Adjust.
2489 2001-09-03 Gary V. Vaughan <gary@gnu.org>
2491 Bootstrap will now work with Libtool 1.4.1 or higher:
2492 * bootstrap: Remove stale autom4te.cache files when
2494 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
2496 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
2497 libtool.m4 directly.
2498 Run libtoolize to refresh ltmain.sh.
2499 * config/ltmain.sh: Deleted.
2500 * acinclude.m4: Deleted.
2501 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
2503 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
2504 implementation for the cvs impaired libtool user.
2506 2001-09-03 Akim Demaille <akim@epita.fr>
2508 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
2510 Avoid using `default' in switch, as it hides useful compiler
2511 warnings when a case is forgotten.
2513 2001-09-03 Akim Demaille <akim@epita.fr>
2515 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
2516 is no such thing as `WITH_MODULES'.
2518 2001-09-03 Akim Demaille <akim@epita.fr>
2520 Improve the test suite's selfcontainedness.
2522 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
2523 (Include, Undivert): Tag the other input files.
2524 * tests/generate.awk: Catch `@comment file:'.
2525 `-I $src' is no longer needed.
2526 `next' is really like `return': the rest is skipped.
2527 Adjust to `input.m4'.
2528 (fatal): New function.
2529 * tests/foo, tests/incl.m4: Remove.
2531 2001-09-01 Gary V. Vaughan <gary@gnu.org>
2533 The shadowing mechanism and, infact, the whole symbol table
2534 implementation was creaking under the weight of the features piled
2535 on top of it. We now have a separate hash table module which will
2536 dynamically resize to keep symbol density withing good performace
2537 limits, and a new symtab module layered above it. Symbol lookups
2538 are now marginally more efficient (since the shadowed flag is no
2539 longer required) and symbol removal, such as on module unload, is
2540 considerably faster due to a reorganisation of the data structures
2543 * src/main.c (main): Don't mention `-H'.
2544 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
2547 * m4/hash.c: New generalised dynamic hash table data structure
2549 * m4/hash.h: Public interface.
2550 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
2551 (libm4_la_SOURCES): Add hash.c.
2552 * m4/symtab.c: More or less rewritten from scratch, within the
2553 bounds of the previous API.
2554 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
2555 call. Updated all callers.
2556 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
2557 declarations to reflect API changes.
2558 (M4INIT): Generate a declaration too, to avoid the warning with
2559 --enable-debug builds.
2562 * m4/utility.c (hash_table_size): Removed.
2563 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
2564 names, which are then looked up by builtin_dumpdef() as necessary.
2565 This implies a small speedup in builtin_symbols(), which discarded
2566 all of the symbol info under the old call.
2567 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
2568 shadowing is implicit in respect to the new data structures.
2569 symbol names are no longer duplicated here, they are stored in the
2570 key field of the hash table.
2571 Moved macro_args and blind_no_args...
2572 (m4_token_data): ...to here.
2573 m4/macro.c (expand_macro): Added a name argument since the symbol
2574 name is no longer copied into each struct m4_symbol. Modified all
2576 (collect_arguments): Ditto.
2577 * modules/m4.c (set_trace): Ditto.
2578 * modules/gnu.c (builtin_symbols): Updated.
2579 * src/freeze.c (produce_symbol_dump): Much improved in light of
2580 the improved symbol table layout.
2582 2001-09-01 Gary V. Vaughan <gary@gnu.org>
2584 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
2586 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
2587 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
2588 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
2589 SYMBOL_HANDLE): Ditto.
2590 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
2591 modules/gnu.c, modules/m4.c, src/freeze.c,
2592 src/main.c: Updated all references.
2594 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
2595 Automake 1.5 chokes on dynamic source file lists, Besides, it is
2596 already listed in m4_LDADD... how did that ever used to work?
2597 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
2599 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
2600 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
2602 * tests/m4: Don't call the m4 wrapper script with libtool, it
2603 works fine all by itself.
2605 2001-08-30 Gary V. Vaughan <gary@gnu.org>
2607 The experimental `changeword' feature never took off, and has
2608 no obvious advantages over `changesyntax' to compensate the
2609 enormous speed penalty it carries:
2610 * configure.in (ENABLE_CHANGEWORD): Removed.
2611 * m4/m4module.h (m4_set_word_regexp): Removed.
2612 * m4/m4private.h (m4_token_data): Removed original_text field.
2613 * m4/utility.c (m4_token_data_orig_text): Removed.
2614 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
2615 * m4/macro.c: Ditto.
2616 * src/main.c: Ditto.
2617 * modules/Makefile.am (changeword.la): Removed.
2618 * modules/changeword.c: File removed.
2619 * doc/m4.texinfo: References to changeword and --word-regexp
2621 * po/POTFILES.in: modules/changeword.c removed.
2622 * tests/atlocal.in (ENABLE_CHANGEWORD): Removed.
2623 * tests/builtins.at (changeword): Test removed.
2625 2001-08-30 Akim Demaille <akim@epita.fr>
2627 * bootstrap.sh: Create aclocal.m4 instead of modifying it.
2628 This also help having a single list of m4 files: in
2630 * config/Makefile.am (STANDARD_MACROS): Rename as...
2631 (ACLOCAL_MACROS): this.
2632 (list-standard-macros): Remove.
2635 2001-08-29 Gary V. Vaughan <gary@gnu.org>
2637 In an attempt to moderate my egomania...
2638 * tests/modules.at: Remove attributions.
2640 * tests/generate.awk: When making substitutions to "@&t@", either
2641 "&" or "\&" in the substitution string argument to gsub refer back
2642 to the matched text. "@\\&t@" seems to work though, Tests 43 and
2645 2001-08-29 Akim Demaille <akim@epita.fr>
2647 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)
2648 (include, indir, multiquotes, patsubst, pushdef/popdef, regexp)
2649 (sync-lines, trace, translit, undivert, wrap): Move to...
2650 * tests/builtins.at: this new file.
2651 * tests/others.at (Discard comments, import-environment): Move to...
2652 * tests/options.at: this new file.
2654 2001-08-29 Akim Demaille <akim@epita.fr>
2656 * tests/others.at (Freezing modules)
2657 (--module-directory: absolute path, modpath2, modpath3)
2658 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
2659 * tests/modules.at: here, new file.
2660 * tests/others.at, tests/generate.awk: Add a banner.
2661 * tests/testsuite.at: Adjust.
2662 (AT_CHECK_M4_FILTER): New, but unused.
2664 2001-08-29 Akim Demaille <akim@epita.fr>
2666 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
2668 * tests/others.at (wrap): Inline wrap.m4.
2669 (shadow): Inline shadow.m4.
2670 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
2671 * tests/m4: Simplify.
2673 2001-08-29 Akim Demaille <akim@epita.fr>
2675 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
2678 2001-08-29 Akim Demaille <akim@epita.fr>
2680 * tests/generate.awk (normalize): s/@__@/@&t@/.
2682 2001-08-28 Akim Demaille <akim@epita.fr>

2686 2001-08-28 Gary V. Vaughan <gary@gnu.org>
2688 * bootstrap (generate.awk): Generate test cases with new script.
2690 2001-08-27 Akim Demaille <akim@epita.fr>
2692 * tests/Makefile.am (installcheck-local): Don't use
2693 `dc_install_base' which is not visible here, but `exec_prefix'
2694 which is clearly the RT anyway.
2695 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
2696 related to testing a now installed m4.
2697 * tests/m4: Do it here.
2699 2001-08-27 Akim Demaille <akim@epita.fr>
2701 * tests/others.at (indir): Formatting change.
2703 2001-08-27 Akim Demaille <akim@epita.fr>
2705 * tests/Makefile.am (installcheck-local): New.
2706 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
2708 Prefer options over envvars.
2709 * src/main.c (main): First bug caught by the test suite (yeah!):
2710 --batch lacked a `break' which resulted in an accidental
2711 invocation of --discard-comments.
2713 2001-08-27 Akim Demaille <akim@epita.fr>
2715 * tests/others.at (capitalize, changeword, comments, ddivert)
2716 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
2717 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
2718 (sysv-args, trace, translit, undivert): Don't rely on files in
2719 examples/: AT_DATA them.
2721 2001-08-27 Akim Demaille <akim@epita.fr>
2723 Let the test suite use a wrapper around the not installed m4 to
2724 pretend it is (installed).
2726 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
2727 such a way that m4 does not process them.
2728 * configure.in: The package name seems to be `m4', not `M4'.
2730 * tests/atlocal.in (at_package, M4): Remove.
2731 * tests/testsuite.at, tests/others.at: Use m4, not $M4.
2733 2001-08-27 Akim Demaille <akim@epita.fr>
2735 * tests/Makefile.am (CLEANFILES): Remove.
2736 (DISTCLEANFILES, clean-local): New.

2739 2001-08-27 Akim Demaille <akim@epita.fr>
2741 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
2742 Don't use aclocal: it's written by hand.
2743 * aclocal.m4: m4_include all the files instead of being built by
2745 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
2746 until it reads the traces by itself.
2747 * configure.in: Require Autoconf 2.42c as we are now using
2748 AC_CONFIG_TESTDIR instead of AT_CONFIG.
2749 Catch unexpanded `jm_' macros.
2750 * config/atconfig.m4: Remove.
2751 * config/error.m4: new.
2752 * config/Makefile.am: Ship the files included by aclocal.m4.
2753 * tests/Makefile.am (TESTSUITE_SOURCES): Rename as...
2754 (TESTSUITE_AT): this, to please Automake.
2755 (TESTSUITE): This target uses autotest/autotest.m4, not
2756 autotest/general.m4.
2757 * tests/testsuite.at: Prereq Autotest 2.52c.
2758 * examples/Makefile.am (pkgdata_DATA): Rename as...
2759 (dist_pkgdata_DATA): this.
2760 * doc/Makefile.am (man_MANS): Rename as...
2761 (dist_man_mans): this.
2763 2001-08-20 Gary V. Vaughan <gary@gnu.org>
2765 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
2766 Robert Collins, building on Cygwin no longer requires Windows
2767 import and export symbol decorations.
2768 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.
2769 * m4/error.h (M4_SCOPE) [cygwin*]: Ditto.

2777 * configure.in (LIBM4_DLL_IMPORT) [cygwin*]: Don't set this
2779 * src/Makefile.am (AM_CPPFLAGS) [cygwin*]: Don't use it either!
2780 * modules/Makefile.am (AM_CPPFLAGS) [cygwin*]: Ditto.
2782 2001-08-20 Gary V. Vaughan <gary@gnu.org>
2784 Ansify the source. Previously we had a mix, where my code was
2785 in a K&R compatible style, and the preexisting code was in ANSI
2786 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
2787 and now the code base is much cleaner.
2789 * m4/system.h: Remove M4_PARAMS macro and all users. Remove
2790 VOID macro and all users.
2791 * m4/m4module.h: Ansify function prototypes and headers.
2792 * m4/builtin.c: Ditto.
2793 * m4/evalparse.c: Ditto.

2807 * src/main.c: Ditto.
2809 2001-08-20 Akim Demaille <akim@epita.fr>
2811 * config/atconfig.m4: s/EOF/ATEOF/, so that configure can be
2812 generated with stock 2.52.
2814 2001-08-20 Akim Demaille <akim@epita.fr>
2816 * config/atconfig.m4: New, until part of Autoconf per se.
2817 * configure.in (AT_CONFIG): Use it.
2819 * tests/mkconfig.sh, tests/atconfig.in, tests/defs: Remove.
2820 * tests/atlocal.in: New.
2821 * tests/generate.awk: For the time being, the empty quadrigraph is
2823 * tests/others.at (changeword, gmp): Check the configuration
2824 variable against `yes'.
2825 * tests/testsuite.at (dnl): Allow it, as it's used all over the
2828 2001-08-20 Akim Demaille <akim@epita.fr>
2830 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
2831 * modules/m4.c (undivert): Disable the possibility of undiverting
2832 several files at once: it is not documented, it is inconsistent
2833 with the other macros, it can be straightforwardly mocked by
2834 several invocations, and most importantly, it prevents the
2835 possibility of other kinds of extension.
2836 Use `m4_numeric_arg'.
2838 2001-08-20 Akim Demaille <akim@epita.fr>
2840 * examples/include.m4: Typo.
2841 * tests/generate.awk: Really add it.
2842 * tests/Makefile.am: Adjust.
2843 * tests/others.at (Discard comments): It sure fails without `-c'.
2844 (include, undivert): Add -I examples/.
2846 2001-08-20 Akim Demaille <akim@epita.fr>
2848 Use sprintf, not ecft and friends since it is standard, portable,
2849 simplifies the code, and since the latter is even deprecated
2850 according to the GNU libc documentation.
2852 * modules/format.c: Drop evct support.
2854 2001-08-19 Gary V. Vaughan <gary@gnu.org>
2856 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Cleaned up. Don't test
2858 * configure.in: ...do it here instead.
2860 * c-boxes.el: Deleted.

2892 * tests/others.at (iso8859): Specify the path to the M4 test file.
2893 * tests/testsuite.at (AT_CHECK_M4): Normalize the path of input
2894 files in error messages.
2896 2001-08-17 Akim Demaille <akim@epita.fr>

2902 `testsuite' is in src, not build.

2907 (generate.at): Install a temporary hack until the actual
2908 generate.awk is added to the repository.
2909 * tests/atconfig.in: New.
2911 2001-08-17 Akim Demaille <akim@epita.fr>

2954 * tests/Makefile.am: Adjust.
2956 2001-08-17 Akim Demaille <akim@epita.fr>
2958 others.at no longer depends on other-tests/.
2960 * tests/others.at (stackovf): You're actually...
2962 (modfreeze, modpath1, modpath2, modpath3, modpath4, modtest, shadow)

2996 2001-08-17 Akim Demaille <akim@epita.fr>
2998 Drop Autoconf 2.13 compatibility.
3000 * configure.in (changeword): No need to undefine it, as anyway if
3001 it's defined, M4sugar moved it as m4_changeword.
3002 And anyway, proper quotation is enough.
3003 (m4_pattern_allow): As it exists in 2.50, just use it.
3004 (AC_OUTPUT): Split in AC_CONFIG_FILES and AC_CONFIG_COMMANDS.
3005 Don't handle Gettext's duties, let it handle them.

3011 (m4_errprint): Use fputs.
3012 * doc/m4.texinfo (Invoking m4) <--error-output>: errprint and
3013 dumpdef are not concerned.
3014 (Dumpdef, Errprint): Emphasize their insensitivity to
3016 * doc/Makefile.am: Add `TAGS' support.
3017 (MAINTAINERCLEANFILES): Remove texinfo.tex and mdate-sh which are

3042 * acinclude.m4: Regenerated.
3043 * m4/ltdl.c: Updated from master copy.
3044 * m4/module.c: Reimplemented to take advantage of advances in

3055 violations, renamed to...
3056 (m4_module_init_func, m4_module_finish_func): ...these,
3058 (M4INIT_HANDLER): Clean way to declare init functions in modules.
3059 (M4FINISH_HANDLER): And similarly for finish functions.
3060 * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER
3061 -- Add indirection to the CONC macro so that arguments are
3063 * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
3064 * modules/shadow.c (m4_init_module): Ditto.
3065 Due to new init function semantics, be careful to perform the
3066 initialisation only on first load.
3067 * modules/perl.c (m4_init_module): Ditto. And Ditto.
3068 (m4_finish_module): Replaced with M4FINISH_HANDLER.

3070 finalisation only on first load.

3072 (m4_module_data): ...structure without all the wrapper fields.
3073 Instances of this new structure are stored associated lt_dlhandles
3074 with lt_dlcaller_data_set().
3075 * m4/builtin.c (m4_builtin_define): Takes a handle argument
3076 instead of the old module argument.
3077 (m4_builtin_table_install): Ditto.
3078 * modules/load.c (m4_resident_module): Removed. This is no
3079 longer implemented as a magic symbol...
3080 * modules/m4.c (m4_resident_module): Ditto.
3081 * modules/load.c (M4INIT_HANDLER): ...the module init function now
3082 uses the ltdl api to make the module resident.
3083 * modules/m4.c (M4INIT_HANDLER): Ditto.
3084 * modules/load.c (builtin_modules): Traverse the loaded module
3085 list with lt_dlhandle_next.

3094 (libm4_la_SOURCES): Delete list.c reference.
3095 * m4/m4private.h (m4_token_data): Add a handle field. This
3096 eliminates many of the searches to find the handle associated with
3097 various tokens that are passed between functions.
3098 (struct m4_symbol): Removed the module field. The
3099 module association does not belong with the symbol...
3100 * m4/input.c (struct m4_builtin): ...it belongs with the builtin
3101 that the module implementation code is from. Added a handle
3103 (m4_push_macro): Add a `handle' argument. Changed all callers.
3104 (init_macro_token): Set the `handle' field for the
3106 * m4/macro.c (expand_argument): Copy the new handle field during
3108 * modules/m4.c (macro_install): Use the new handle field to
3109 optimise the search for the correct builtin structure, and pass
3110 the handle details to m4_builtin_define.
3112 2001-08-15 Akim Demaille <akim@epita.fr>
3114 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Be sure `m4/' exists
3115 when creating `m4/obstack.h'.
3116 * tests/Makefile.am (TESTS_ENVIRONMENT): Pass top_srcdir and
3118 * tests/defs: Make them absolute.
3119 (CDPATH) Neutralize.
3120 * tests/gethem: Use them.
3122 2001-08-14 Gary V. Vaughan <gary@gnu.org>
3124 * config/ltmain.sh: Doh! Import again for a quoting fix that
3125 prevented any regression test from passing.
3127 * m4/m4module.h (obstack.h): Choose between installed version
3128 and shipped version based on configure tests.
3129 * src/freeze.c (obstack.h): Ditto.
3131 * acconfig.h: Removed. No longer required.
3133 * bootstrap: Rewritten to play nicely with Autoconf 2.5x.

3135 them to AC_INIT and AM_INIT_AUTOMAKE.
3136 * Makefile.am (AUTOMAKE_OPTIONS): Remove `gnits' which would
3137 disallow MY_NAME and MY_VERSION arguments to AM_INIT_AUTOMAKE.
3138 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Don't choke on
3139 shell variable m4_cv_func_obstack_h.
3140 * tests/defs (M4): Be more careful about relative path to libtool
3141 script and m4 binary by using $srcdir.
3143 * src/main.c (main): Use lt_dlinsertsearchdir to prepend -M
3144 optargs to the existing libltdl search path.
3145 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.
3146 * m4/ltdl.c: Updated.
3148 * config/ltmain.sh: Ditto.
3150 2001-08-11 Gary V. Vaughan <gary@gnu.org>
3152 * src/main.c (main): Add `-b' (for `batch') mode switch to force
3153 interactive mode off.
3155 2001-08-10 Akim Demaille <akim@epita.fr>

3214 * module/m4.c (m4_resident_module): Ditto.
3215 * m4/modules.c (m4_module_load): Use new ltdl resident modules
3216 feature to mark modules as resident if they export
3217 `m4_resident_module' as TRUE.
3218 (m4_module_unload): Do not remove resident modules, and take care
3219 with symbol insertion and deletion with resident modules.
3220 * m4/ltdl.c, m4/ltdl.h: Update to latest unreleased versions to
3221 use resident modules feature.
3223 2000-11-30 Gary V. Vaughan <gary@gnu.org>
3225 * TODO: Updated. Removed some cruft that has since been fixed
3226 or implemented. Added some more entries.
3229 * modules/README: Updated.
3230 * doc/m4.texinfo: Updated.
3232 * modules/gnu.c (builtin_functions): Make indir orthogonal to
3233 builtin, in that each is recognised as a macro only with parameters
3234 (builtin_indir): Passing 0 arguments is now an error, as with
3237 * src/main.c (usage): Added missing description of `-c' option.

3284 Move the implementation of GMP support for the mpeval() builtin
3285 into a loadable module that depends on libgmp. mpeval() and
3286 eval() share a common parser, now in m4/evalparser.c; the code
3287 in m4/numb.c and m4/numb.h is now physically split between
3288 m4/eval.c (the eval() backend) and modules/mpeval.c (the
3289 mpeval() backend), rather than being differentiated by cpp
3290 macros and multiple inclusion. The mpeval module is always
3291 built but will generate an diagnostic if it is used from an
3292 installation that didn't link in the gmp library.
3293 * modules/Makefile.am: build and install the new mpeval module.
3294 * modules/mpeval.c: Now contains the former parts of m4/numb.c
3295 and m4/numb.h that are required for gmp support in mpeval().
3296 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
3297 * m4/evalmp.c: Removed.
3298 * m4/m4module.h: Removed conditional prototype for
3300 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
3301 and m4/numb.h that do not rely on gmp.
3302 * m4/evalparse.c: New file, contains the shared parts of the
3303 eval() and evalmp() parser implementations, and is no longer
3304 unencumbered by cpp magic to uncover the right parts.
3305 * m4/numb.h: Removed. It's former contents are split between
3306 m4/eval.c and modules/mpeval.c.
3309 * tests/other-tests/changeword.test: New test. Rudimentary
3310 testing of changeword builtin runs only if --wnable-changeword
3311 was used at configure time.
3312 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
3313 alternation correctly. Split into two expressions to compensate.
3314 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
3315 * modules/Makefile.am: Build changeword module.
3316 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
3317 only when --enable-changeword was passed to configure.
3318 (builtin_changeword): If --enable-changeword was not used, then
3319 report that changeword() builtin has no support in m4 binary.
3321 2000-11-28 Gary V. Vaughan <gary@gnu.org>
3323 * src/main.c (main): Fixed a particularly nasty bug is
3324 user_search_path setting -- the -M flag processing must be
3325 extremely careful with search path ordering, or else the default
3326 installed module directory (possibly containing modules from a
3327 previous release) is placed earlier in the search path than any -M
3328 arguments (which are relied upon to load uninstalled modules with
3329 most of the tests in the regresion suite).
3331 * modules/load.c (builtin_load): Nasty hack to prevent adding
3332 symbols to symtab again if a module is loaded more than once.
3333 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
3335 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
3336 possible NULL pointer dereference.
3338 * m4/module.c (m4_module_find_by_modname): Renamed from
3339 m4_module_modname_find. Fixed all references.
3340 (m4_module_find_by_builtin): New function.
3342 * modules/modfreeze.test: load the `load' module with each
3344 * src/freeze.c (produce_frozen_state): Simplified in light of
3345 module field in m4_symbol. Allow a third argument for text macros
3346 to name the originating module.
3347 (reload_frozen_state): ditto.
3348 * m4/m4module.h: Fixup prototypes.
3349 * m4/builtin.h (m4_builtin_define): Add a module argument so
3350 that symbols can be registered against the defining module.
3351 (m4_macro_define): ditto.
3352 * m4/m4private.h (m4_symbol): Make the module field const to save
3353 on casting in the rest of the code.
3354 (SYMBOL_MODULE): New macro.
3356 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
3357 symbol reference maintenance bugs when removing a symbol from the
3360 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
3362 2000-11-27 Gary V. Vaughan <gary@gnu.org>
3364 * configure.in (m4_cv_func_obstack): A better check for whether
3365 libc has an obstack implementation.
3366 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
3368 * configure.in (--with-modules): Changed semantics. This
3369 option is now used to list modules to be preopened.
3370 * src/m4.h: #include "ltdl.h" unconditionally.
3371 * src/main.c: Removed all dependencies on WITH_MODULES.
3372 * src/freeze.c: ditto.
3373 * modules/Makefile.am: ditto.
3374 * m4/m4.c (builtin_m4exit): ditto.
3375 * modules/modpath1.test: ditto.
3376 * modules/modpath2.test: ditto.
3377 * modules/modpath3.test: ditto.
3378 * modules/modpath4.test: ditto.

3380 * modules/shadow.test: ditto.
3381 * modules/unload.test: ditto.
3383 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
3384 comes up on demand in LTLIBOBJS now.
3385 * configure.in (getopt_long): Creating and relying on a link for
3386 getopt.h on hosts with no getopt_long() of thier own works
3387 correctly now. This is necessary so that callers of getopt_long()
3388 can simply `#include <getopt.h>': the naive way of doing this
3389 would end up using our own getopt.h and the installed
3390 getopt_long(), which is asking for trouble!
3391 (obstack_init): A similar argument applies to obstack.h and
3394 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
3395 On Solaris-2.5 (at least) the native dlopen implementation
3396 gets confused about m4.o when looking for module "m4". This
3397 version always looks for .la an .$lib_ext suffixed names first
3398 to work around the problem. Sigh.
3400 * po/POTFILES.in: Take account of these file movements.
3401 * src/Makefile.am (m4_SOURCES): removed eval.c.
3402 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
3403 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
3404 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
3405 * modules/m4.c (builtin_eval): Use m4_evaluate().
3406 * m4/eval.c: Moved here from src/eval.c to facilitate
3407 implementation of eval() builtin as part of the `m4' loadable
3409 (m4_evaluate): renamed from evaluate for namespace cleanliness.
3410 * m4/numb.c: Moved here from src/numb.c, since it is #included
3411 into eval.c at compile time.
3412 * m4/m4module.h (m4_evaluate): Added prototype.
3413 * src/m4.h (evaluate): Removed prototype.
3415 2000-11-25 Gary V. Vaughan <gary@gnu.org>
3417 * modules/perl.c (builtin_perleval): Use PL_na for
3418 compatibility with perl-5.6.
3420 * src/main.c (main): It is now safe to
3421 ``m4_module_install("m4")'', without tripping over the m4
3423 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
3424 versions having fixed the insidious module search order bug.
3426 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
3427 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
3429 * configure.in: Figure out whether to use the installed
3430 getopt.h or the supplied one.
3431 * src/Makefile.am: ditto.
3433 * po/POTFILES.in: List files in their new positions.
3435 * config/ltmain.sh: This needs to be checked in to match the
3436 libtool macros copied to acinclude.m4 (until a released
3437 libtool copes with m4's needs).
3438 * bootstrap: Run gettextize.
3440 2000-11-24 Gary V. Vaughan <gary@gnu.org>
3442 * AUTHORS: Added my details.
3445 * bootstrap: temporary update until released libtool catches up.
3447 * All files: Use new GNU GPL copyright blurb with current contact
3450 * configure.in (LTLIBOBJS): Use canonical code for calculation of
3453 * config: renamed acm4 directory to config to be more like
3454 other autoconfiscated packages.
3456 * configure.in (M4_AC_CHECK_DEBUGGING): Use it.
3457 * config/debug.m4: New file implementing configure macros to add
3458 suitable debug flags to the compiler invocation.
3460 * modules/load.c: New file implementing the ``load'' and
3461 ``unload'' builtins.

3481 * modules/gnu.c: New file implementing a new loadable module wuth
3482 definitions for all the gnu extension builtins.
3483 * modules/format.c: Moved here from src/format.c. Now included
3486 * src/main.c (main): Load the traditional module if m4 was
3487 started in `no_gnu_extensions' mode.
3488 * modules/traditional.c: New file implementing the ``unix'' macro,
3489 required when m4 is executed in traditional mode, as a loadable
3492 * src/main.c: Renamed from m4.c to avoid confusion with
3494 (main): Always load the m4 module.
3495 * modules/m4.c: New file implementing a new loadable module with
3496 definitions for all m4 builtins that are not gnu extensions.
3498 * m4/Makefile.am: Adjusted to take new files below into account.
3499 * m4/m4module.h: Prototypes for exported functions and types moved
3500 to this directory from the src directory.

3502 the migration of all builtin implementations to loadable modules.
3503 * m4/macro.c: Moved this file here from the src directory,
3504 renaming all exported symbols to use the prefix ``m4_''.
3505 * m4/builtin.c: ditto.
3506 * m4/module.c: ditto.
3507 * m4/symtab.c: ditto.
3508 * m4/debug.c: ditto.

3510 * m4/output.c: ditto.
3512 * m4/ltdl.h, m4/ltdl.c: ditto.
3513 * m4/utility.c: Odd functions moved here from files in the src
3514 directory to facilitate builtin migration.
3516 2000-08-12 Gary V. Vaughan <gary@gnu.org>
3518 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
3519 error message, to make translators' jobs a little easier.
3520 (builtin_builtin): ditto.
3521 (builtin_traceon): ditto.
3522 (builtin_traceoff): ditto.
3523 Reported by Akim Demaille <akim@epita.fr>
3525 * m4/Makefile.am (pkgincdir): Deleted. Use automake's built in
3526 pkgincludedir instead.

3549 makeinfo calculates them for us, and to make any future
3550 reorganisation easier.
3551 (Frozen files): Document format version 2.
3552 `V' now takes argument `2'.
3553 `F' can take a single argument if symbol and builtin names
3554 are the same, or 3 arguments if the builtin is from a module.

3710 odule defines an identical name.
3711 * src/symtab.c (remove_table_reference_symbols): remove all symbol
3712 table entries which refer to a given builtin table.
3713 * src/builtin.c (remove_tables): Use it!
3715 2000-07-13 Thomas Tanner <tanner@ffii.org>
3717 * Makefile.am (SUBDIRS): we need modules/ for "make dist"

3739 2000-01-18 Gary V. Vaughan <gary@gnu.org>
3741 * README: Caveat about nls not supported by dll architecture on
3744 * TODO (MODULE SPECIFIC ISSUES): more ideas for the future.

3767 increment serial number.
3769 * Makefile.am (SUBDIRS): Moved @MODULES_DIR@ to compile before
3770 src dir and immediately after libm4 is built for confidence that
3771 it doesn't rely on the src directory.
3772 (SUBDIRS): Moved doc dir to the end since helptoman.pl and
3773 makeinfo stop the build on cygwin (because they don't work).
3775 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
3777 * m4/m4private.h: ...is not a public header, so moved to src.
3778 Add `#include <config.h>', `#define _COMPILING_M4' and
3780 * m4/Makefile.am (noinst_HEADERS): remove m4private.h.
3781 * src/Makefile.am (noinst_HEADERS): add m4private.h.

3802 and then in $(top_srcdir)/lib (for eg. "m4private.h").
3803 * src/Makefile.am (m4_LDADD): replace libi/libm4.la with
3805 * m4/m4error.h: Renamed error.h, for installation to
3806 $prefix/include/m4..

3821 From Akim Demaille <akim@epita.fr>
3823 2000-01-17 Gary V. Vaughan <gary@gnu.org>
3825 * src/ltdl.c: Use access() to abort doomed module load attempts
3826 if module file does not exist.
3828 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
3829 getopt1.o will already be used if appropriate, so I moved getopt.c
3830 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
3832 * modules/modpath1.test: Use correct filename in header line.
3833 * modules/modpath2.test: ditto.
3834 * modules/modpath3.test: ditto.
3835 * modules/modpath4.test: ditto.
3837 Without these changes lt_dlopen("test") attempts to
3838 LoadLibrary("/bin/test") on Windows, which although harmless
3839 generates a spurious error message which spoils most of the tests:
3840 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
3841 (TESTS): s/test.test /modtest.test /
3842 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /

3845 * modules/modpath2.test: ditto.
3846 * modules/modpath4.test: ditto.
3847 * modules/modpath3.test: s/-m test /-m modtest /
3848 * modules/shadow.m4: use {un,}loadmodule(`modtest').
3850 2000-01-16 Gary V. Vaughan <gary@gnu.org>
3852 * src/ltdl.c (find_file): Updated to new version with fixed memory
3853 allocation bug in `next'.
3854 * src/ltdl.h: updated to match.
3856 * modules/Makefile.am: Cleaned up and reordered.
3858 2000-01-16 Rene' Seindal <rene@seindal.dk>
3860 * modules/Makefile.am (TESTS): New tests for the module system.
3862 * modules/*.test: New files.
3864 * src/m4.c (main): Added call to module_init().
3865 Treats -M and -m as the arguments -D -U and -t, ie deferred.
3867 * src/m4.h: Added declaration of module_init().
3869 * src/module.c (module_init): No longer static
3871 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
3872 Added to shut up automake about non standard libtool library

3877 * modules/README: Changed example from unload.m4 to shadow.m4
3879 * modules/shadow.m4: Renamed from unload.m4
3881 * modules/Makefile.am (EXTRA_DIST): Removed unload.m4.

3886 2000-01-12 Gary V. Vaughan <gary@gnu.org>
3888 * doc/help2man.pl: updated to version 1.020.
3890 * lib/COPYING.LIB: updated to version 2.1.
3892 * lib/m4module.h: restructure the M4_SCOPE code to work when
3893 creating a dll which links with libm4.la and both DLL_EXPORT
3894 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
3897 2000-01-11 Gary V. Vaughan <gary@gnu.org>
3899 Merged the following changes from my tree:
3901 1999-06-15 Gary V. Vaughan <gary@gnu.org>
3903 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
3904 ported to compile shared libs.
3906 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
3907 use `__declspec(dllimport)' when linking libm4.la on win32.
3908 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
3910 * configure.in (M4OBJS): Discover whether we need the shipped
3911 implementation of getopt_long.
3912 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
3913 main binary here, as opposed to the module library in lib/libm4.la.
3915 1999-06-14 Gary V. Vaughan <gary@gnu.org>
3917 * modules/README: Updated to describe the improved libltdl based
3919 * README (cygwin): Added some compilation notes for building m4
3920 correctly under cygwin.
3921 * TODO: Cleaned out the entries for the module system since they
3922 are now implemented.
3924 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
3925 all instances of __P with M4_PARAMS.
3927 * lib/getdate.h: removed unreferenced file.
3929 * lib/m4private.h: New file to define the private interface to the
3930 token_data struct, which must be shared between m4module.c, and
3931 builtin.c but not exported to modules built from the installed
3932 m4module.h since it's size changes depending on compile time
3935 * src/m4.h: Lots of stuff moved to lib/m4module.h.
3937 * lib/m4module.h: New file to define the interface available when
3938 compiling m4 modules.
3939 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
3940 necessary for module compilation into this new file.
3942 * lib/Makefile.am (include_HEADERS): install headers (renamed to
3943 avoid nameclash with other system headers) necessary for compiling
3945 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
3946 so that modules can include the (renamed) installed headers and
3947 be guaranteed a matching implementation.
3948 * lib/m4error.h: renamed from error.h.
3949 * lib/m4obstack.h: renamed from obstack.h.
3950 * lib/m4regex.h: renamed from regex.h.
3951 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
3952 implementation, simply include the shipped version
3953 unconditionally, otherwise it is hard for a module to know
3954 whether the m4obstack.h header it is using matches the
3955 implementation it ends up linking against.
3956 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
3959 1999-05-18 Gary V. Vaughan <gary@gnu.org>
3961 * examples/misc.test: Don't run this test on machines which don't
3962 have a root user in /etc/passwd (e.g. cygwin).
3964 * tests/get-them (/^@example$/): Error messages might have a
3965 ``.exe'' suffix to the program name, or else use the libtool
3966 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
3967 of these cases are now catered for when comparing error messages
3969 * tests/other-tests/*.test: ditto.
3970 * examples/*.test: ditto.
3972 * tests/defs (M4): use libtool execute mode.
3973 * examples/defs (M4): ditto.
3975 * tests/get-them (END): explicitly close any open file.
3976 (printthem): In a regular expression, '{' is the start of a repeat
3977 count! Use `[{]' for a literal open brace.
3978 (/^@node /): Don't use substr on a string shorter than the trim
3981 1999-05-17 Gary V. Vaughan <gary@gnu.org>
3983 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
3985 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
3987 2000-01-10 Andreas Schwab <schwab@suse.de>
3989 * tests/other-tests/gmp.test: Find config.sh in build directory.
3991 * configure.in: Find tests/mkconfig.sh in $srcdir.
3993 * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in
3994 <signal.h> (for SUS2 compliant systems).

3999 2000-01-10 Rene' Seindal <rene@seindal.dk>
4003 * TODO, NEWS: Cleaned up and updated.
4005 * src/m4.c (main): New variable exit_status for exit status in
4006 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
4007 file cannot be read instead of EXIT_SUCCESS.
4009 * src/builtin.c (m4_indir): Changed error message to help
4010 translators (from Akim Demaille <demaille@inf.enst.fr>).
4012 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
4015 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
4018 * src/input.c (match_input): Reordering of code, to avoid multiple
4019 calls to push_string_init() from obstack_grow(), which can happen
4020 with some compilers (found and fixed by James Bonfield
4021 <jkb@mrc-lmb.cam.ac.uk>).
4023 * src/stackovf.c: Added prototypes for ultrix.
4024 (setup_stackovf_trap): Added __P to cast.
4025 (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>)
4027 2000-01-09 Rene' Seindal <rene@seindal.dk>
4029 * doc/m4.texinfo (Changequote): Added comment about changing
4030 quotes when the old quote is a part of the new.
4032 * src/builtin.c (expand_ranges): Added break after trailing dash.
4033 This caused misbehavious on some systems (found and fixed by Akim
4034 Demaille <demaille@inf.enst.fr>).
4036 * AUTHORS: Thomas Tanner included
4038 * acconfig.h: Added entry for ss_sp (see below).
4040 * configure.in (use_stackovf): Added check for stack_t with member
4041 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert
4042 <eggert@twinsun.com>).
4044 * doc/m4.texinfo (Frozen files): Added a simpler example for
4045 generating frozen files from several input files.
4047 1999-11-14 Paul Eggert <eggert@twinsun.com>
4049 * po/POTFILES.in: Add lib/getopt.c, lib/obstack.c,
4050 lib/regex.c, lib/xmalloc.c.
4052 1999-11-10 Rene' Seindal <rene@seindal.dk>
4054 * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal.
4056 * src/module.c: reindented.
4057 (module_load): return if this is a repeated load of same module.
4058 (module_init): slight change of logic to avoid repeated
4059 initialisation debug messages.
4061 * Makefile.am (DIST_SUBDIRS): Added to ensure modules/ is included
4062 in the distribution.

4074 1999-11-09 Paul Eggert <eggert@twinsun.com>
4076 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
4077 and zero, as Solaris 7 cc does.
4078 (bcopy): Remove macro; no longer needed with new obstack.h.
4080 * src/output.c (freeze_diversions): Don't assume that a
4081 diversion size can fit in `int'. Check for diversion file
4082 size too large to be printed with `unsigned long'.
4084 * src/Makefile.am (CFLAGS): Omit -Wall.
4086 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.
4088 * src/debug.c (trace_format):

4102 * src/module.c: entirely new implementation using libltdl.
4103 * po/POTFILES.in: added src/module.c.

4105 are modules, not linktime libraries.
4106 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
4107 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
4108 avoidance on exported symbols.

4115 * src/m4.c (--load-module): dynamically load named runtime module
4116 into running executable before reading the source.
4117 (--module-directory): prepend a directory to the module search
4119 (module_init()): Do this the first time we load a module instead;
4120 if the module subsystem is broken normal m4 scripts can still run.
4121 * src/m4.h (install_builtin_table): is now exported.
4123 1999-03-26 Gary V. Vaughan <gary@gnu.org>
4125 * src/module.c: removed. No longer required.

4141 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
4142 * acm4/gettext.m4: removed. It causes a multiple definition vs.
4143 the installed gettext.m4 file when running aclocal.
4145 1999-03-25 Gary V. Vaughan <gary@gnu.org>
4147 * configure.in (AM_INIT_AUTOMAKE): bumped version number to

4154 (LDFLAGS): Added `-module -avoid-version' flags to build
4155 versionless module libraries.

4157 (module_unload_all): use libltdl.
4158 * src/m4.c (module_init): initialise module loading on demand for
4159 better diagnostics, and so that m4 will still work even if
4160 the module code is broken.
4161 * src/m4.h (module_init): removed. No longer relevant.
4162 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on
4163 exported symbols for compatibility with dlpreopening.
4164 * modules/test.c (m4_macro_table, m4_init_module,
4165 m4_finish_module): ditto.
4166 * modules/time.c (m4_macro_table): ditto.
4168 * bootstrap: New file. Runs all the autoutils in the right order
4169 after a fresh checkout, or a make maintainer-clean.
4171 1999-02-18 Akim Demaille <demaille@inf.enst.fr>
4173 * src/builtin.c (dump_symbols): New function, factoring common
4174 content of m4_dumpdef and m4_symbols.
4175 (m4_dumpdef): Use it.
4176 (m4_symbols): New function, implementing `symbols'. Use it.
4177 * doc/m4.texinfo: Fixed missing commas after @xref, so that the
4178 file compile with modern makeinfo.

4180 (direntry): Modernize.
4182 1998-12-11 Rene' Seindal <rene@seindal.dk>

4190 * src/module.c (module_try_load): Don't try to be clever and
4191 overwrite argument string. Instead allocate all constructed
4192 strings locally, since they can have arbitrary lengths. Make
4193 arguments pointers to const.
4194 (module_search): Simplify due to above change.
4196 1998-11-29 Rene' Seindal <rene@seindal.dk>

4222 1998-11-28 Rene' Seindal <rene@seindal.dk>
4224 * src/m4.c (main): New option --import-environment (no single
4227 * When configured with --with-gmp both the normal (fast) eval()
4228 and the gmp aware mpeval() are defined. To restore previous
4229 bahaviour use "define(`eval', defn(`mpeval'))".
4231 * tests/other-tests/gmp.m4: Changed to use mpeval().
4233 * src/evalmp.c: New file for compiling eval.c as gmp aware.
4234 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
4236 * src/eval.c: Now includes "numb.c" directly. Everything in this
4237 file must by static, except evaluate(), which is changed to
4238 mp_evaluate() if USE_GMP in force.
4240 * src/numb.c: Changed to be included by eval.c instead of being
4241 compiled separately. Everything is declared static.
4243 * src/numb.h: Removed declarations of functions, as numb.c is now
4246 * src/builtin.c: Declaration of m4_mpeval() added.
4247 Inserted `mpeval' in builtin table.

4256 * src/m4.c (main): m4 --version also shows which options were used
4257 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
4259 1998-11-27 Rene' Seindal <rene@seindal.dk>
4261 * Error messages now always print program name before input file
4262 name as specified by GNU coding standards. Reported by Akim
4263 Demaille <demaille@inf.enst.fr>.
4265 * doc/m4.texinfo (Include): Change due to changed error message
4269 * tests/get-them: Minor change to sed script due to changed error
4272 * src/m4.c (print_program_name): New func used to print program
4273 name, input file and line number in error (). Used as an
4274 error_print_progname handler.

4282 * Updated to libtool 1.2b.
4284 * src/builtin.c (install_builtin_table): Added braces to avoid
4285 warning of ambiguous 'else'.
4287 * src/module.c: Inserted search path code from path.c modified to
4289 (module_init): Configured default path used only if M4MODPATH is
4291 (module_try_load): Now reads libMODULE.la as generated by libtool
4292 for actual module name.
4293 (module_load): Gives better error messages on failure.
4295 * src/m4.h: Added declarations of structures and functions for
4296 generic search path handling.

4299 functions of more generic search path handling.
4301 1998-11-24 Rene' Seindal <rene@seindal.dk>
4303 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
4304 included gettext, as <libintl.h> might not be found
4305 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
4307 1998-11-22 Rene' Seindal <rene@seindal.dk>
4309 * src/output.c (insert_diversion): Fixed bug that might cause m4
4310 to read from standard output! Triggered by input
4311 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
4312 so now 'undivert(0)' does nothing.
4314 1998-11-18 Rene' Seindal <rene@seindal.dk>
4318 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
4319 could be changed when compiling a illegal regexp, causing later
4320 use of the regexp to dump core.
4322 * src/module.c (module_load): Changed error message to conform to
4325 * src/m4.c (usage): Added message about reporting bugs.

4339 libtool. The modules are compiled as shared libraries, and are
4340 renamed when installed.
4342 * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
4343 USE_SHL_LOAD to HAVE_SHL_LOAD
4345 * src/builtin.c (shipout_string): Now tests for a NULL string.

4361 getpwuid, hostname, rand, srand, getenv, setenv, unsetenv, uname.
4363 * src/builtin.c (shipout_string): New convenience function for
4364 builtins and modules.

4375 These two are now initialised by autoconf macros.
4377 * src/path.c (module_env_init): MODULE_PATH is always on the
4380 * src/Makefile.am: Now generated pathconf.h which defined the
4381 default MODULE_PATH.
4383 * configure.in (pkglibexecdir): Added defintion of pkglibexecdir,
4384 where modules are installed.
4386 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
4387 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
4388 build and install automatically, and it is prepared for other
4389 interfacec than dlopen().
4391 * src/builtin.c (predefined_tab): Added __m4_version__ for the
4392 current version of GNU m4. It is a GNU extension.
4394 1998-11-14 Rene' Seindal <rene@seindal.dk>

4424 * tests/Makefile.am (GENERATED_TESTS): Renamed gentest to
4427 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): Added manually
4428 maintained tests in tests/other-tests. These currently tests for
4429 8-bit transparency, multiple precision arithmetic and sync-line
4430 output. Test for stackoverflow detection does not work.

4472 1998-10-07 René Seindal <rene@seindal.dk>
4476 * tests/Makefile.am (GENERATED_TESTS): Changed .m4 extension to
4477 .test, as the files are no longer just m4 input.
4479 * tests/get-them (FILE): Changed .m4 extension to .test.

4486 (expand_argument): Do.
4488 * src/input.c (next_token): SPACE and NUM/OTHER characters are only
4489 grouped together iff both quote and comment strings are single
4490 character. Otherwise they might include a comment/quote leader.
4491 (next_token): Returns new token type TOKEN_SPACE.
4493 * src/builtin.c (push_builtin_table): New function to push a
4494 builtin_table on the stack without installing its contents.

4500 1998-10-04 René Seindal <rene@seindal.dk>
4504 * configure.in (ALL_LINGUAS): Added Polish pl.po
4506 1998-10-03 René Seindal <rene@seindal.dk>

4518 skip_space, bad_argc), and the macros ARG() and DECLARE().
4520 * src/builtin.c (install_builtin_table): New function. Each
4521 module brings in a builtin_table, which is pushed on a stack.
4522 (struct builtin_table): New struct for list of builtin_tables.
4523 (m4_loadmodule): New function to implement builtin "loadmodule".
4524 (shipout_int): No longer static, to be used by modules.

4545 * configure.in: Added modules/Makefile to AC_OUTPUT.
4547 * configure.in: Added code to implement --with-modules. Tests for
4550 * acconfig.h: Added WITH_MODULES
4552 1998-10-02 René Seindal <rene@seindal.dk>
4554 * examples/Makefile.am (pkgdata_DATA): Removed special target for
4555 check and variables TESTS. These tests are now run from the
4558 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
4559 directory. The files stay there but the tests are run from the
4562 * tests/Makefile.am (EXTRA_DIST): Added run-test.
4564 * tests/run-test: New file. Run a test manually
4566 * tests/Makefile.am, tests/get_them: Moved automatically generated
4567 tests (from the manual) to sub directory tests/gentest/. The
4568 tests/ directory had gotten a bit messy.
4570 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4572 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\

4588 `C'. Reported by Ulrich Drepper.
4590 * Makefile.am (SUBDIRS): Removed checks directory
4591 * configure.in (AC_OUTPUT): Removed checks/Makefile
4593 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
4594 the space when m4.texinfo is edited and whitespace.el is active.
4595 (Defn,example): idem.
4597 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4599 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
4600 ../COPYING. ../Makefile is a file which is certainly present when
4601 test is executed in testSubDir. One can't be sure that the COPYING
4602 file is in .. or ../.. in all situations, the ../Makefile is
4605 * doc/m4.texinfo (Include): adjusted expected test output
4606 according to new tests, i.e. the input will always come from the
4607 file `in' created by the test.
4609 * tests/Makefile.am: Added three lines at the top to get
4610 esyscmd.1.test working.
4612 * tests/get-them: modified to generate clearer tests who will need
4613 less maintenance when new test examples are created in
4614 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
4615 need the generic file `defs') shell scripts creating `in', `ok',
4616 `out' and when apropriate `okerr' and `err' in the directory
4617 `testSubDir' when executed. The compare of `ok' and `out'
4618 (and of `okerr' and `err') will be the exit status of the test.
4619 `out' must match `ok' (and `okerr' must match `err') for the test
4622 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
4623 the tests generated by tests/get-them getting it input normally
4624 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
4625 (dot) before the numeric part) is reserved for all other (hand
4626 written) tests. The `+' means one or more times.
4628 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4630 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to

4657 * src/builtin.c (m4_changesyntax): Added builtin macro
4658 "changesyntax" to modify the syntax table.
4660 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax
4661 table. All categories are assigned a syntax code and tokens are
4662 read according to this table.
4664 1998-08-09 René Seindal <rene@seindal.dk>
4666 * src/numb.{c,h}: New files, implements multiple precision eval
4667 using GNU gmp. Originally submitted by John Gerard Makecki
4668 (johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.
4670 * doc/m4.texinfo (Eval): Added documentation for multiple
4671 precision arithmetic library support.
4673 * src/m4.{c,h}, src/eval.c, src/builtin.c, configure.in: Changes
4674 to accommodate multiple precision eval.
4676 1998-08-07 René Seindal <rene@seindal.dk>
4678 * src/input.c (MATCH, match_input), src/m4.h: changed definition
4679 of comment and quote strings to `unsigned int' to allow eight bit
4680 chars (reported by andrewb@zip.com.au (Andrew Bettison)).
4682 * src/builtin.c, doc/m4.texinfo: Builtin `syncoutput' added by
4683 patch from Mike Howard <mike@clove.com>
4685 1998-08-06 René Seindal <rene@seindal.dk>
4687 * gettext.m4: corrected AM_WITH_NLS to handle use of installed
4690 1998-08-03 René Seindal <rene@seindal.dk>
4694 * src/m4.h: Added ifdef ENABLE_NLS around include of <libintl.h>
4695 and _ macro. M4 now builds with --disable-nls.
4697 * src/m4.c (main): reintroduced textdomain(PACKAGE) to get gettext
4698 to look for right message catalogs. Call indef'ed by ENABLE_NLS.
4700 * configure.in (ALL_LINGUAS): Added complete list of translations:
4701 de fr it ja nl ru sv.
4703 1998-05-22 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4707 * src/m4.c: #include <signal.h> not <sys/signal.h>.
4709 * src/Makefile.am: CFLAGS = -Wall @CFLAGS@.
4711 * checks/Makefile.am: explicit list tests in CHECKS.
4713 * configure.in, {,src,doc,lib,examples,checks}/Makefile.am,

4719 Used libitize (0.4) to update.
4721 * configure.in, ABOUT-NLS, intl/*, po/*: Added gettextize
4722 (0.10.25) support. Removed LOCALE, fr.msg, m4.cod and adjusted
4725 * src/stackovf.c: #ifdef USE_STACKOVF ... #endif to (de-)activate
4726 stack overflow functionality.

4780 1994-11-01 François Pinard <pinard@iro.umontreal.ca>
4782 * src/macro.c (collect_arguments): Cast obstack arguments to
4783 (voidstar), so avoiding compiler warnings.
4784 Reported by Joseph E. Sacco.
4786 * src/freeze.c (produce_frozen_state): Cast printed lengths to
4787 (int) so they correspond to %d format items.
4788 Reported by Joseph E. Sacco.
4790 * src/m4.c (main): Cast the argument to xfree to (voidstar).
4791 * src/symtab.c (free_symbol): Idem.

4805 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
4806 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
4807 defines __STDC__ to 0, for indicating it is *not* ANSI!
4808 Reported by Kaveh R. Ghazi.

4820 Reported by John David Anglin.
4822 * src/ansi2knr.c: New version, sent by Peter Deutsch.
4823 * aclocal.m4 (fp_C_PROTOTYPES): Substitute empty or ansi2knr for
4824 ANSI2KNR, depending on the fact the compiler is ANSI or not.
4825 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
4826 Remove the sed filter after ansi2knr for debug.c. Use $O instead
4827 of $U, put underline in extensions rather than in basenames. Use
4828 implicit rules, now that regularity makes this possible.
4829 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
4830 of ansi2knr whenever it is needed.
4831 * configure.in: Adjusted for correct STACKOVF substitution.
4832 * src/debug.c (trace_format): When not __STDC__, use (...) as a
4833 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.
4834 Reported by David MacKenzie.

4844 * Makefile.in (all, install, uninstall): Depend on Makefile.
4846 * Makefile.in: For actions invoking $(MAKE) from within compound
4847 sh statements, exit non-zero if the sub-make fails. Otherwise,
4848 the top-level make may exit successfully when it should fail.
4849 Reported by Jim Kingdon.
4851 * {,/*}Makefile.in: Use && after all cd, in case they fail.
4853 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.
4854 (dist): Use PRODUCT and VERSION instead of tricks on .fname.
4855 * configure.in: Substitute PRODUCT and VERSION.

4879 Reported by Jim Meyering.
4881 1994-09-23 François Pinard <pinard@iro.umontreal.ca>
4883 * src/stackovf.c: Declare the handler_t typedef earlier in the

4886 casting sigsegv_handler.
4887 Reported by Robert Bernstein.
4889 * src/m4.c (main): Initialize program_name to argv[0] without

4896 Reported by Karl Berry.
4898 1994-09-14 François Pinard <pinard@iro.umontreal.ca>
4900 * lib/Makefile.in (mostlyclean): Added.
4901 (TAGS): Make in $(srcdir).
4903 * configure.in: Use `choke me' in test, like everywhere!
4905 * {doc,examples,lib,src}/Makefile.in (check): Deleted, as
4906 unreacheable and useless.
4908 * doc/Makefile.in (texclean): Deleted, merged in mostlyclean.

4911 (distclean): Do not remove TAGS.
4912 (realclean): Remove it.
4913 * Makefile.in: Make TAGS in lib also, not just in src.
4914 Reported by Karl Berry.
4916 * Makefile.in (distclean, realclean): Instead of recursively
4917 calling $(MAKE) for the -local part, allow parallel execution of
4918 -recursive and -local, only delay the removal of config.status,
4919 which is repeated in both goals.
4921 1994-09-13 François Pinard <pinard@iro.umontreal.ca>
4925 * Makefile.in: Group all *clean-recursive goals in one, using sed
4926 to remove `-recursive' while calling make recursively. Also, use
4927 a subshell for each recursive $(MAKE).
4928 Reported by Jim Meyering.
4930 * src/m4.h (memcpy): Define with bcopy for BSD systems.
4931 Reported by Kaveh R. Ghazi.
4933 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
4934 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
4937 * configure.in: Use date instead of touch for stamp-h.
4938 * Makefile.in (stamp-h.in): Idem.
4940 * Makefile.in (distclean, realclean): Force serial execution of
4941 both goals, in case parallel makes are being used.
4942 Reported by Jim Meyering.
4944 * src/Makefile.in (DISTFILES): Distribute TAGS.
4945 (distclean): Do not remove TAGS.

4958 Reported by John David Anglin.
4960 * doc/Makefile.in (texclean): Remove *.cps and *.fns too.
4961 Reported by Eric Backus.

4968 Reported by Jim Meyering.
4970 1994-09-06 François Pinard <pinard@iro.umontreal.ca>
4972 * configure.in: Correct stack overflow detection logic, taking
4973 care of systems having only incomplete implementations (like for
4974 Pyramid 9820 OSx 5.0d).
4975 Reported by Kaveh R. Ghazi.
4977 * src/Makefile.in (TAGS): Remote -t from etags call.
4979 1994-09-02 François Pinard <pinard@iro.umontreal.ca>
4981 * lib/Makefile.in (install): Depend on all.
4983 1994-08-31 François Pinard <pinard@iro.umontreal.ca>

4986 Reported by Jim Meyering and John David Anglin.
4988 * Makefile.in (distclean-local): Delete config.log.
4989 Reported by Jim Meyering.
4991 Solidify frozen files with respect to -P:
4992 * src/m4.c: Have -P set prefix_all_buitins variable instead of
4993 calling a function by that name. Declare the variable.
4994 * src/m4.h: Adjust declaration for prefix_all_buitins.
4995 * src/builtin.c (builtin_init): Merge in functionality from
4996 previous prefix_all_buitins function, while making entries in the
4997 symbol table, but not modifying the builtin description itself.
4999 * src/freeze.c (reload_frozen_state): Add a useless `break;',
5000 because *many* compilers do not accept an empty `default:'.
5001 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
5002 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
5004 * configure.in: Use AC_TYPE_SIGNAL.
5005 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.
5006 Reported by Robert Bernstein.
5008 * checks/Makefile.in (check): Modify PATH so check-them will find
5009 m4 in the src directory.
5010 * Makefile.in (check): Don't.
5011 Reported by Akiko Matsushita and Jim Meyering.

5014 functions, for implementing a global MAXIMUM_TOTAL_SIZE instead of
5015 a per buffer MAXIMUM_BUFFER_SIZE.
5017 * src/output.c (output_text): New function, for optimizing the
5018 output of strings of characters. Use it.
5020 1994-08-30 François Pinard <pinard@iro.umontreal.ca>
5022 * doc, src: New directories reorganizing the distribution.
5023 * doc/Makefile.in, src/Makefile.in, examples/Makefile.in: New
5025 * Makefile.in: Adjusted.
5026 * configure.in: Configure new Makefiles.
5028 * m4.h: Declare STRING typedef. Use it for comment and quote
5029 strings, adjusting all references. (This is the rudiments of a
5030 beginning for the eventual withdrawal of NUL terminated strings.)
5031 * output.c (shipout_text): Accept a length parameter, and use it.
5032 All callers adjusted.
5034 1994-08-29 François Pinard <pinard@iro.umontreal.ca>
5036 * m4.h: Include <unistd.h> if it exists.

5049 (output_init): Allocate only diversion 0.
5050 (make_diversion): Allocate new diversions as needed.
5051 * m4.h, m4.c: Remove NDIVERSIONS and ndiversion related stuff.
5052 * m4.c: Still accept -N, but do nothing with it.
5053 Reported by David MacKenzie.
5056 * output.c (freeze_diversions): New function.
5057 * m4.h: Declare freeze_diversions.
5058 * freeze.c: Document frozen file format, revise it, call
5059 freeze_diversions to add diversions to frozen format, and code to
5060 reload them properly.
5061 * m4.c: Do not undivert automatically at end when status being
5062 frozen. Do not call builtin_init when reloading frozen state.
5064 Speed up diversion processing:
5065 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
5066 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
5067 structure and variables, cached variables out of output_diversion,
5068 reallocate_diversion_for and OUTPUT_CHARACTER.
5069 (shipout_text, make_diversion, insert_diversion): Adapted to new
5071 (insert_file): Use better buffering.
5072 Reported by David MacKenzie.

5076 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
5077 dist works from another build directory.
5079 1994-08-27 François Pinard <pinard@iro.umontreal.ca>
5081 * symtab.c (hack_all_symbols): Use hash_table_size instead of
5082 constant HASHMAX, for -H option to work better.
5084 * builtin.c (DECLARE): Simplify by using _ ().
5086 * freeze.c: New file.
5087 * Makefile.in: Compile it, distribute it.
5088 * m4.c: Recognize, document and process --freeze-state (-F) and
5089 --reload-state (-R) options. Pass a true flag to builtin_init
5090 only if no reloading some state.
5091 * builtin.c (define_builtin): Remove static specifier.
5092 (find_builtin_by_name): Remove static specifier.
5093 (builtin_init): Accept and obey a flag argument.

5096 1994-08-24 François Pinard <pinard@iro.umontreal.ca>
5098 * builtin.c (dumpdef_cmp): Rewrite so the cast protect the const
5101 * configure.in: Implement --with-dmalloc.
5102 * acconfig.h: Document WITH_DMALLOC.
5103 * m4.h: Add code for when WITH_DMALLOC.
5105 1994-08-15 François Pinard <pinard@iro.umontreal.ca>
5107 * m4.c (long_options): Use "error-output", the dash was missing.
5108 Reported by Akiko Matsushita.
5110 1994-08-12 François Pinard <pinard@iro.umontreal.ca>
5112 * m4.h: Include <sys/types.h>.
5113 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
5114 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
5116 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
5118 * builtin.c (dump_args): Declare len as size_t, not int.
5120 * debug.c: Prototype the forward declaration of debug_set_file.
5122 * builtin.c (m4_undivert): Replace div by file, for avoiding the
5123 shadowing of this variable.
5124 * output.c (insert_diversion): Idem.
5126 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
5127 (input_init): Duplicate default quote and comment strings.
5128 (set_quotes): Free previous quote strings in all cases. Duplicate
5129 even default quote strings.
5130 (set_comment): Free previous comment strings in all cases.
5131 Duplicate even default comment strings.
5133 * configure.in: Updated for Autoconf 2.0.
5134 * Makefile.in (distclean-local): Also delete config.cache.
5136 * m4.c (usage): Reorganize the --help output by topic. Include a
5137 description for debugging flags.
5139 1994-07-29 François Pinard <pinard@iro.umontreal.ca>
5141 * configure.in: If sigaction is available and SA_ONSTACK defined,
5142 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
5143 defined, use sigvec. Else don't compile stackovf.c.
5144 * stackovf.c (setup_stackovf_trap): Idem.
5145 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
5148 1994-07-21 François Pinard <pinard@iro.umontreal.ca>
5150 * m4.c (usage): Replace printf par fputs.
5152 1994-07-18 François Pinard <pinard@iro.umontreal.ca>
5156 1994-07-17 François Pinard <pinard@iro.umontreal.ca>
5158 * configure.in: Check for sigaction and sigvec. Add a new delayed
5159 check for RLIMIT_STACK, combine in the checking for getrlimit.
5160 All those things are not universally available.
5161 * stackovf.c: Split setting up the trap handler and catching
5162 signals, for better taking care of various configure outcomes.
5163 * examples/stackovf.sh: Correct a typo.
5164 Reported by Eric Backus, Jim Avera and Jim Meyering.
5166 1994-07-16 François Pinard <pinard@iro.umontreal.ca>
5168 * ansi2knr.c: New version sent by its author, Peter Deutsch.
5170 1994-07-15 François Pinard <pinard@iro.umontreal.ca>
5172 * Makefile.in: Modify so parallel make will not try making
5173 lib/libm4.a twice simultaneously.
5174 Reported by Jim Meyering.
5176 1994-07-14 François Pinard <pinard@iro.umontreal.ca>
5178 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
5179 error message, for when no code possibility exists. Even if this
5180 line is completely #ifdef'ed out, it brings a syntax error.
5181 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
5183 * Makefile.in (install): Have install depend on all too, for lib
5184 to be remade as needed.
5186 * examples/stackovf.sh: Try ksh, bsh and bash for shells
5187 providing ulimit, instead of using only ksh.
5188 Reported by Jim Avera and Joseph E. Sacco.
5190 1994-07-12 François Pinard <pinard@iro.umontreal.ca>
5192 * Makefile.in (check): Have it depend on all instead of m4. In
5193 this way, a change in lib will be detected and processed.
5195 * builtin.c (numeric_arg): Use strtol and verify the conversion,
5196 instead of using sscanf which stops as soon as there is a
5197 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
5198 and divert(1xyzzy) were all accepted without any warning or error
5200 * m4.h: Declare strtol as long if not including stdlib.h.
5201 * configure.in: Check for limits.h, and replace strtol if missing.
5202 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
5203 * lib/strtol.c: New file, from elsewhere.
5204 Reported by Andreas Schwab.
5206 1994-07-07 François Pinard <pinard@iro.umontreal.ca>
5208 * macro.c (expand_macro): Cast value to (boolean) prior to
5209 assigning it to traced.
5210 Reported by Tom McConnell.
5212 * Makefile.in (m4): Always make all in lib first.
5213 Reported by Jim Meyering.
5215 1994-07-06 Jim Avera <jima@netcom.com>
5217 * stackovf.c: Isolated OS-dependent sections; Improved portability,
5218 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
5219 handlers), and a default error message if the fault address is not
5220 available (when neither siginfo.h nor BSD sigcontext are supported).
5221 * configure.in: Changes for stackovf.h: Check for sigcontext,
5222 sigaction, sigstack, and define rlim_t as int if necessary.
5223 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
5224 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
5225 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
5227 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
5229 * configure.in: Use AC_SET_MAKE.
5230 * Makefile.in: Use @SET_MAKE@.
5231 Reported by Jim Meyering.
5233 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
5234 Reported by Ian Taylor.
5236 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
5238 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
5239 because siginfo.h is unrelated to standard headers, and siginfo.h
5240 is already checked for.
5241 Reported by Joseph E. Sacco.
5243 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
5245 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
5248 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
5250 * builtin.c (substitute): Use \& to represent this part of the
5251 string which was matched by the whole regexp, instead of
5252 representing the whole string. Any usage of \0 issues a warning
5253 and acts like \&, it will disappear in some subsequent release.
5255 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
5257 * m4.c: Complete prototype for forwarded declaration of usage.
5259 * input.c (init_macro_token): Correct own reference in error
5260 message. Previous name get_macro_func was referred to instead.
5261 (next_char): Correct own reference in error message. Previous
5262 name advance_input was referred to instead.
5264 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
5265 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
5266 and_term, not_term, logical_not_term, cmp_term, shift_term,
5267 add_term, mult_term, exp_term, unary_term, simple_term): Add
5268 prototype to forwarded declarations. Declare parameter v1 as
5269 eval_t * instead of int *. Same for local variable v2 in dyadic
5270 functions. Same for result in exp_term.
5271 * builtin.c (m4_eval): Declare value as eval_t instead of int.
5272 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
5273 unsigned_eval_t instead of unsigned int. Change casts accordingly.
5274 (shipout_int): Cast first argument of ntoa to eval_t.
5275 Reported by Thorsten Ohl.
5277 * macro.c: Complete the prototypes of forwarded expand_macro and
5279 Reported by Thorsten Ohl.
5281 * m4.h: Define voidstar as void * or char * depending on __STDC__.
5282 The Ultrix 3.1 compiler cannot do much with void pointers.
5284 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
5285 * m4.c (xfree): Replace void * by voidstar.
5286 Reported by Tom McConnell.
5288 * ansi2knr.1: New, from elsewhere.
5289 * Makefile.in (DISTFILES): Distribute ansi2knr.1
5291 * Makefile.in (stamp-h.in): Avoid running ./config.status if
5292 stamp-h does not exist yet. This avoids running it a second time
5293 just after the initial ./configure.
5294 Reported by David MacKenzie and Tom McConnell.
5296 * m4.h: Replace the enum debug_info declaration with a series of
5297 #define's. The Ultrix 3.1 compiler would otherwise need casting
5298 (int) to most references, when used in expressions.
5299 Reported by Tom McConnell.
5301 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
5303 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
5304 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
5305 calls the compiler. Previously, FP_PROTOTYPES was only calling
5306 the preprocessor; by not being subject to CFLAGS, this was
5307 discouraging those flags asking for ANSI compilation.

5325 * input.c (set_word_regexp): Do not try to initialize the array
5326 test from a string, this does not work with non-ANSI compilers.
5327 Reported by Eric Backus.
5329 * Makefile.in (dist): Clean examples/ before saving it.
5330 (distclean-local): Also remove stamp-h.
5331 Reported by Eric Backus.

5399 EXIT_FAILURE if not otherwise done by header files.
5400 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.

5414 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
5415 also tested it on a Sun Sparc workstation running SunOS 4.x.
5417 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
5418 49.format check, abusing a `union values' argument with sprintf
5419 without selecting the proper field. Now, save the formatting type
5420 first, delaying the fetch of the corresponding argument.
5421 Reported by Joseph E. Sacco and Tom Quinn.
5423 * format.c (format): Remove const from char *fmt declaration when
5424 not HAVE_EFGCVT, because a NUL may be forced into it.
5426 * m4.h: Declare atof() when not STDC_HEADERS.
5427 Reported by Joseph E. Sacco.
5429 * Regenerate configure using Autoconf 1.11, this corrects a
5430 problem about an incorrect cpp seting on NeXT 3.1.
5431 Reported by Alexander Lehmann.
5433 1994-06-05 François Pinard <pinard@iro.umontreal.ca>

5470 warning from gcc about `repl' possibly used before defined.
5471 Reported by Jim Meyering.
5473 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
5474 Reported by Jim Meyering.
5476 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
5478 * m4.h: Move the conditional definition of volatile after the
5479 inclusion of system files, because they may define it first.
5481 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
5483 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
5484 get around a problem with Alpha make seeing a syntax error, there.
5485 Reported by Vern Paxson.
5487 1994-01-03 François Pinard <pinard@iro.umontreal.ca>
5489 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.

5503 Use them in exit() and usage() calls.
5505 1993-11-27 François Pinard <pinard@iro.umontreal.ca>
5507 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
5508 syserr() macro. Delete errref, add reference_error and M4ERROR.
5509 * m4.c: Replace errref, which was returning an input reference
5510 string, with reference_error, which prints it on standard error.
5511 * builtin.c, output.c: Use errno as second parameter to error,
5512 instead of using syserr() with %s.
5513 * *.c: Use M4ERROR instead of error: no more errref() with %s.
5514 Doing so, the program name appears after the input reference
5515 instead of before, which eases M-x next-error processing.
5517 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
5519 * checks/get-them: Escape braces with backslashes in patterns,

5556 * input.c (input_init): Initialize quote and comment strings
5557 explicitely instead of calling set_quotes and set_comment: by

5561 expected is on the left and the obtained on the right.
5563 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR

5565 internal_error, add declaration for error_message_prefix.
5566 * m4.c: Delete m4error, warning, fatal and internal_error
5567 routines, add error_message_prefix routine.
5568 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
5569 warning with WARNING*, fatal with FATAL* and internal_error with
5571 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
5572 this is not needed anymore.
5574 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
5575 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
5576 and debug_message, add declaration for debug_message_prefix.

5579 debug_message_prefix routine.
5580 * builtin.c, debug.c: Replace debug_print routine calls with
5581 DEBUG_PRINT* macro calls.

5830 1993-01-01 François Pinard <pinard@iro.umontreal.ca>
5832 * Makefile.in, lib/Makefile.in: Reinstate $(CPPFLAGS), use it.
5833 Richard wants it there.
5835 1992-12-27 François Pinard <pinard@iro.umontreal.ca>
5837 * Makefile.in: Add DEFS to MDEFINES.
5838 * lib/Makefile.in (.c.o): Remove $(CPPFLAGS).
5839 (libm4.a): Remove the library before creating it.
5840 (distclean): Remove tags and TAGS too.
5842 1992-12-23 François Pinard <pinard@iro.umontreal.ca>
5844 * Makefile.in (dvi, m4.dvi): New goals.
5846 * builtin.c, eval.c, format.c, input.c, m4.[ch], m4.texinfo,
5847 macro.c, output.c, path.c, symtab.c: Change Copyright from
5848 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
5850 * examples/divert.m4: Deleted, this bug has been corrected.
5852 * Makefile.in (texclean, mostlyclean): New goals.
5854 * Makefile.in (clean): Remove clutter from ansi2knr.
5855 Reported by Pierre Gaumond.
5857 1992-12-20 François Pinard <pinard@iro.umontreal.ca>
5859 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
5860 might well use CFLAGS is s/he needs it.
5862 * Makefile.in: Allow installation of info files from a separate
5864 Reported by Jason Merrill.
5865 Reported by David MacKenzie.
5866 Reported by Skip Montanaro.
5867 Reported by Erez Zadok.
5868 Reported by Assar Westerlund.
5870 1992-12-19 François Pinard <pinard@iro.umontreal.ca>
5873 This is still a beta release for the future GNU m4 version 1.1.
5875 * lib/alloca.c: New, from elsewhere.
5876 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
5878 * m4.h: Do not define index/rindex if already defined. If
5879 FALSE/TRUE are already defined, do not redefine them, but merely
5880 define boolean typedef to int.
5882 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
5883 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
5884 because some C compilers do not like connectives with #ifdef.
5885 * m4.h: Define `volatile' only if __GNUC__, instead of once for
5886 __GNUC__ and once for __STDC__.
5887 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
5889 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
5890 Makefile dependencies. Without it, make keeps destroying and
5891 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
5893 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
5894 to diversion/DIVERSION, this was a spelling error.
5896 * m4.c: Declare version[], remove #include "version.h".
5897 * version.h: Deleted.
5898 * Makefile.in: Remove references to version.h.
5900 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
5901 production, by using a simpler and more robust algorithm. This
5902 solves the problem of synclines sometimes written in the middle of
5903 an output line. Delete sync_line() and output_lines variable.
5904 * m4.h: Remove sync_line prototype and output_lines declaration.
5905 * input.c (next_char), output.c (shipout_text): Remove references
5907 * input.c (push_file, pop_file): Merely put the value -1 in
5908 output_current_line instead of calling sync_line, for delaying a
5909 single `#line NUM FILE' before next output line. Do not test
5910 for sync_output, because this is unnecessary clutter.
5911 * output.c (make_divertion, insert_divertion): Idem.
5912 * input.c: Rename must_advance_line to start_of_input_line, for
5915 * debug.c (trace_header): Select a new debug line format, which
5916 better complies with GNU standards for formatting error messages.
5917 With option `-dfl', M-x next-error might be used on the output.
5918 * m4.c (vmesg): Adjust format of error output to GNU standards.
5919 * m4.texinfo: Adjust examples for `make check' to work.
5921 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
5922 case for enum debug_info constants, which were all lower case.
5924 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
5926 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
5927 collected patches. I tried a few times using newer regex.[ch], it
5928 mysteriously stopped aborting with this one. Insecure feeling...
5929 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
5931 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
5933 * m4.c: Change `--no-warnings' to `--silent'.
5934 Reported by David MacKenzie.
5936 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
5937 leave it off for now. See comment in m4.c for justification.
5938 Reported by David MacKenzie.
5940 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
5941 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
5943 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
5945 * Makefile.in: Ensure recursive cleaning is done before local
5946 cleaning for all clean goals.
5948 * builtin.c (ntoa): Ensure the value is always interpreted as a
5949 signed quantity, whatever the radix is.
5951 1992-11-18 Jim Meyering <meyering@idefix>
5953 * builtin.c, format.c, input.c: Split long lines.
5954 * m4.c: Use typedef macro_definition instead of struct
5956 * symtab.c: Use typedef symbol instead of struct symbol.
5958 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
5960 * *.[ch]: Remove all trailing whitespace, in code and comments.
5962 * configure.in: Find some awk.
5963 * Makefile.in: Add $(AWK) to MDEFINES.
5964 * checks/Makefile.in: Transmit $(AWK) to get_them.
5965 * checks/get_them: Use $AWK instead of gawk. Add a close in the
5966 awk script when switching files, because without this, mawk runs
5967 out of file descriptors.
5969 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
5971 * Makefile.in (realclean): Delete m4.info*.
5972 Reported by Jim Meyering.
5974 * Makefile.in: Adjust and link with checks/Makefile.
5975 * checks/Makefile.in: New.
5976 * configure.in: Output checks/Makefile.
5978 * checks/get_them: Have the dnl header of each test more
5979 recognizable by next-error, also use a better message.
5981 1992-11-16 Jim Meyering <meyering@idefix>
5983 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
5984 And use that only if __GNUC__ since we're using it's GCC-specific
5985 semantics that tell the compiler the associated function doesn't
5988 * builtin.c (substitute): Don't use character as an array index.
5989 (dumpdef_cmp): Make formal arguments `const void *' to avoid
5990 warnings with gcc -W -Wall on systems with qsort prototype.
5991 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
5994 * eval.c (most functions): Add parentheses to assignments used
5995 as truth values go avoid warnings from gcc -Wall.
5997 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
5998 any functions that don't need external scope.
6000 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
6001 (many functions and arrays): Declare `const'.
6003 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
6005 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
6006 removing the declaration from m4.h. Also rename false to FALSE
6009 * lib/Makefile.in (Makefile): New goal.
6011 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
6012 so heavily loaded. It gets more easily overridable, calling make.
6013 Reported by Jim Meyering.
6015 * Makefile.in (dist): Get .fname from the current directory name,
6016 instead of from version.h. I need updating many files manually,
6017 when the version changes, version.h is just one of them.
6019 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
6021 * m4.h: Remove the tag `boolean' on the enum introducing typedef
6022 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
6023 Reported by Tom McConnell.
6025 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
6027 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
6028 39.cleardiv, which were describing missing or spurious newlines.
6029 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
6030 do not depend on machine word size, `/bin/false' implementation,
6031 or `wc' output format. `make check' is more dependable, now.
6033 * checks/check_them: Summarize the failed tests by listing their
6034 name, at end. If none, issue `All checks successful'. Output
6035 `Checking' instead of `Input file:'.
6037 * checks/get_them, checks/check_them: Reindented.
6039 * Makefile.in (dist): chmod a+r before making the tar file.
6041 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
6043 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
6045 * input.c (next_token): Reinitialize token_buttom just after using
6046 it as a watermark with obstack_free. Or else, a future token, big
6047 enough for triggering reallocation of the obstack chunk, could
6048 void the initialized value of token_buttom, later causing panic in
6049 obstack_free. Rename token_buttom to token_bottom everywhere.
6051 * m4.h: Before declaring errno, first include <errno.h> and
6052 ensure that it does not define errno.
6053 Reported by Richard Stallman.
6055 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
6057 * builtin.c: Define and use DECLARE macro for builtins.
6059 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
6060 argument, this is a common idiom for introducing long comments.
6062 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
6063 arguments. The last argument was silently ignored.
6065 * m4.c (cmd_error): Add a missing semicolon before va_end().
6067 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
6069 * Makefile.in: Now handle protoized sources. Define and use U.
6070 Compile and use ansi2knr with old compilers. Update DISTFILES.
6071 Add `aclocal.m4' to `configure' dependencies.
6072 * ansi2knr.c: New, from Ghostscript distribution.
6073 * configure.in: Define U through FP_PROTOTYPES for old compilers.
6074 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
6075 * aclocal.m4: New, provide FP_PROTOTYPES.
6076 * m4.h: Conditionnaly protoized through Args, save for varags.
6077 * builtin.c: Protoized. Then:
6078 Include <sys/types.h> if size_t is not defined, before "regex.h".
6079 (m4_ifelse): Fetch built-in name properly for diagnostic.
6080 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
6081 (m4_regexp): Add const to `msg' declaration.
6082 (m4_patsubst): Add const to `msg' declaration.
6083 * debug.c: Protoized, save for varargs.
6084 * eval.c: Protoized.
6085 * format.c: Protoized.
6086 * input.c: Protoized.
6087 * m4.c: Protoized, save for varargs. Then:
6088 (xfree): Accept void * instead of char *.
6089 (xmalloc): Return void * instead of char *.
6090 (xrealloc): Accept and return void * instead of char *.
6091 * macro.c: Protoized.
6092 * output.c: Protoized.
6093 * path.c: Protoized. Then cast some (char *) over xmalloc's.
6094 * symtab.c: Protoized.
6096 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
6098 * m4.texinfo: Remove directory from diagnostics in 30.include,
6099 51.eval, 56.errprint and 57.m4exit tests.
6101 * m4.h: Remove declarations for int or void system functions, they
6102 cause more conflicting trouble than they make good.
6104 * configure.in: Avoid configuration header file. Add some tests.
6105 * m4.h: Remove #include "config.h".
6106 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
6107 Then, rewritten for better compliance with GNU standards.
6109 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
6111 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
6112 because of a misplaced #endif.
6114 * Many *.[hc] files: Correct intra-line spacing here and there,
6115 according to GNU indent 1.6 advice.
6117 * configure.in: New, using Autoconf 1.2.
6118 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
6119 * Delete old configure.in, configure, etc/configure.in,
6120 etc/configure, lib/configure.in, lib/configure and config/*.
6121 Reported by Jason Merrill.
6123 * symtab.c (hash): Change (char) NULL to '\0'.
6124 Reported by Jason Merrill.
6126 * Delete .vers, etc/newdist.sh, etc/newvers.sh and
6127 etc/nextvers.sh. Release numbers will be edited `by hand'.
6128 * version.h: De-automatize, force value in.
6130 * m4.c: Changes in order to use a newer getopt.h.
6131 Reported by David MacKenzie.
6133 * checks/: New name for examples/.
6134 * checks/get_them: New location for etc/get_examples.
6135 * checks/check_them: New location for etc/check_examples.
6136 * Makefile.in, checks/get_them, checks/check_them: Adjust.
6137 * lib/vfprintf.c: New location for etc/vfprintf.c.
6138 * Delete empty etc/.
6139 * examples/: New name for test/.
6141 1992-03-10 François Pinard <pinard@iro.umontreal.ca>
6143 * Makefile.in (check): Add m4 as dependency.
6145 * m4.c: Accept --no-warnings instead of --no_warnings, and
6146 --no-gnu-extensions instead of --no_gnu_extensions. Make the
6147 usage message more informative.
6148 Reported by David MacKenzie.
6150 1992-03-09 François Pinard <pinard@iro.umontreal.ca>
6152 * etc/check_examples: New name for check_examples.sh.

6158 * Many *.[hc] files: GNU indent'ed, with further fine tuning of
6159 code disposition by hand.
6161 1992-03-08 François Pinard <pinard@iro.umontreal.ca>
6163 * m4.h: Delete definitions for abort() and exit().
6164 Reported by Richard Stallman.
6166 * config/hmake-unicos, config/s-unicos.h: New files.
6167 Reported by Hal Peterson.
6169 * eval.c (exp_term): Have N^0 return 1.
6170 Reported by Michael Fetterman.
6172 * eval.c, input.c, m4.h: Remove last comma in enums.
6173 Reported by Mike Lijewski.
6175 * Transfer of maintenance duties from René to François.
6177 1991-10-24 René Seindal <seindal@diku.dk>

6187 missing or superflous arguments to built-in macros.
6189 * Added default options via the M4OPTS environment variable.
6191 * The built-in format can now be configured to use sprintf as
6192 the formatting engine, for systems without [efg]cvt(3).
6194 * GNU library code is moved to the ./lib subdirectory; other
6195 utility files are now in ./etc.
6197 * Several minor bugs have been fixed.
6199 1991-07-26 René Seindal <seindal@diku.dk>

6202 Francois Pinard and Roland H. Pesch for providing me with reports.
6204 * The builtins incr and decr are now implemented without use of
6207 * The builtin indir is added, to allow for indirect macro calls
6208 (allows use of "illegal" macro names).
6210 * The debugging and tracing facilities has been enhanced
6211 considerably. See the manual for details.
6213 * The -tMACRO option is added, marks MACRO for tracing as soon
6216 * Builtins are traced after renaming iff they were before.
6218 * Named files can now be undiverted.
6220 * The -Nnum option can be used to increase the number of
6221 divertions available.
6223 * Calling changecom without arguments now disables all comment
6226 * The function m4_patsubst() is now consistently declared
6229 * A bug in dnl is fixed.
