3 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
4 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
5 and libtoolize does a better job of ltdl importing now too, so
6 take advantage of that while updating the tree:
8 * acm4, config: Moved from here...
9 * ltdl/m4, ltdl/config: ...to here.
10 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
11 src/Makefile.am, tests/Makefile.am: Removed...
12 * Makefile.am: ...and migrated to here, with adjustments to
13 compensate for relative path differences.
14 * commit: Adjust relative paths.
15 * configure.ac: Adjust relative paths.
16 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
18 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
19 the meanwhile, CVS HEAD libtool is needed.
20 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
21 stricly new enough, we also need a patch.
22 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
23 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
24 (gl_MODULES): Don't list getopt and version-etc, as they don't
26 * bootstrap: After running gnulib-tool to import the listed
27 modules, fetch getopt and version-etc into src manually.
28 (ltdldir): Change to ltdl.
29 * src/main.c: Adjust for changes in version-etc API.
30 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
31 but works when the getopt module isn't to be included in the lib.
32 * README: Add note about patching autoconf and automake to
35 2005-05-02 Matt Kraai <kraai@debian.org> (tiny change)
37 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=84416
38 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
39 empty file rather than to a nonexistent file. This closes a
41 * modules/m4.c (m4_maketemp): Implement the above, by using
42 mkstemp rather than mktemp.
44 2005-05-01 Gary V. Vaughan <gary@gnu.org>
46 The FSF are moving offices today. Changed their contact address
47 in all files from `59 Temple Place, Suite 330, MA 02111-1307' to
48 `51 Franklin Street, Fifth Floor, MA 02110-1301'.
50 2005-03-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
52 * tests/Makefile (clean-local): Ignore testsuite cleanup
55 2005-03-11 Per Bothner <per@bothner.com> (tiny change)
57 * tests/Makefile (clean-local): Only run the testsuite cleanup
58 if the testsuite has been generated.
60 2005-02-11 Stepan Kasal <kasal@ucw.cz>
62 * TODO: slight clarification of the example of qindir usage.
64 2005-02-08 Gary V. Vaughan <gary@gnu.org>
66 * TODO: Add qindir requirement, and defn bug.
67 From Stepan Kasal <kasal@ucw.cz>
69 2005-02-08 Stepan Kasal <kasal@ucw.cz>
71 * TODO: Add ``execution stack'', fix a typo.
72 * doc/m4.texinfo: Typos.
74 2004-12-24 Eric Blake <ebb9@byu.net>
76 * configure.ac (INCLUDE_STDBOOL_H): Account for gnulib's move
77 to the gnu subdirectory.
78 * acm4/m4-error.m4 (INCLUDE_ERROR_H): Likewise.
79 * acm4/m4-obstack.m4 (INCLUDE_OBSTACK_H): Likewise.
80 * acm4/m4-regex.m4 (INCLUDE_REGEX_H): Likewise.
81 * m4/system_.h: Likewise, in non-configured includes.
83 2004-10-14 Noah Misch <noah@cs.caltech.edu>,
84 Gary V. Vaughan <gary@gnu.org>
86 * m4/m4.c (m4_context_field_table, m4_context_opt_bit_table):
87 Protect definitions from macro expansion under -DNDEBUG by
88 parenthesising the expanded function names.
89 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
90 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
91 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
92 (m4_is_syntax_macro_escaped): Similarly protect function
93 definitions from macro expansion under -DNDEBUG by #undefing the
94 matching macro names before each definition. Also, move all the
95 function definitions to the end of the file so that any
96 invocations in the rest of the file pick up the fast macro
98 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)
99 (m4_set_debug_file, m4_set_trace_messages)
100 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
101 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
102 (m4_set_max_debug_arg_length_opt): New fast macro versions of the
103 option setter functions.
105 2004-09-23 Gary V. Vaughan <gary@gnu.org>
107 * src/main.c: Include gnulib files from the correct directory.
109 * gnulib/*: Don't store any of the gnulib files in arch, as they
110 generate spurious changes.
111 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
112 gnulib macros now share our macro directory.
113 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
114 * bootstrap: Call gnulib-tool to import from the gnulib tree.
115 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
116 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
117 the gettext macros from autopoint that overwrite the gnulib-tool
118 imported versions. Import sources and Makefile.am into the `gnu'
119 directory. Changed all callers.
120 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
121 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
122 for imported modules.
123 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
124 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
125 hardcoding the gnulib macros they wrap.
127 2004-07-15 Gary V. Vaughan <gary@gnu.org>
129 Latest CVS libtool can preload modules in libraries, including
130 its own module loaders! Tweak m4 so that it doesn't try to treat
131 libltdl's module loaders as m4 modules when freezing and on exit:
133 * gnulib/acm4/*.m4: Don't store these files in arch since they
134 generate spurious changes.
135 * bootstrap: Simplify initial libtoolize call, since CVS
136 libtoolize is smarter these days.
137 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
139 * m4/module.h (m4__module_exit): Missing declaration.
140 * m4/m4private.h (m4__module_next): New function declaration.
141 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
142 encapsulation. Changed all callers.
143 (m4__module_interface): New function to verify m4 loadable module
145 (m4__module_init): Register the interface validator.
146 (m4__module_exit): Only close my own modules.
147 * modules/m4.c (unistd.h): Provide missing declaration.
148 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
149 (m4_expand_ranges): More missing declarations.
150 * modules/modtest.c (export_test): Ditto.
151 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
152 * src/main.c (main): Bump copyright year.
153 * tests/modules.at: Fix sed syntax error.
156 2004-06-17 Gary V. Vaughan <gary@gnu.org>
158 Tweaking to enable compilation with latest CVS libtool and
159 libltdl. We can't just dump the library files directly into the
160 m4 directory anymore now that libltdl is built from pieces itself:
162 * bootstrap: Rewritten to use latest libtoolize sanely, and to
163 set up libltdl subdirectory.
164 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
165 gnulib subdirectory's config.
166 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
167 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
169 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
170 configure.ac, so use AC_WITH_LTDL instead.
171 * Makefile.am (SUBDIRS): Add libltdl.
172 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
174 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
175 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
176 (libm4_la_LIBADD): Add LIBLTDL.
177 * m4/ltdl.c, m4/ltdl.h: Removed.
178 * m4/m4module.h: Include canonical ltdl.h.
181 2004-06-14 Gary V. Vaughan <gary@gnu.org>
183 * gnulib/import: Now updates makefile fragments, and configure.ac.
184 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
185 * gnulib/m4/Makefile.am: include it.
186 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
187 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
188 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
189 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
190 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
191 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,
192 gnulib/acm4/lib-ld.m4, gnulib/acm4/lib-prefix.m4,
193 gnulib/acm4/error.m4, gnulib/acm4/po.m4, gnulib/acm4/regex.m4,
194 gnulib/acm4/stdbool.m4, gnulib/acm4/stdint_h.m4,
195 gnulib/acm4/uintmax_t.m4, gnulib/acm4/ulonglong.m4,
196 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
197 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
198 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
200 * gnulib/m4/getopt_int.h: New source file from latest gnulib
202 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
203 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,
204 gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
205 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
206 Updated source files from latest gnulib.
208 2004-02-29 Gary V. Vaughan <gary@gnu.org>
210 * config/mailnotify: New file for mailing commit notifications,
211 imported from cvs-utils.
212 * commit: Updated from cvs-utils and tweaked for m4.
214 2003-12-01 Gary V. Vaughan <gary@gnu.org>
216 * config/mkstamp: Updated from CVS libtool.
217 * configure.ac: Generate a gnu coding standards compliant version
218 number, and use it for the banner.
219 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
220 mhen the TIMESTAMP changes in ChangeLog, but the file modification
221 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
222 contain the previous version number.
223 * src/main.c: Make --version output conform to the GNU standard.
225 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
226 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
227 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
228 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
229 time_la_SOURCES): ...so that these are defaulted correctly, and
230 can be removed from this file.
231 (AM_LDFLAGS): Add -module...
232 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
233 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
234 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
235 the individual settings can be removed.
236 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
237 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
238 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
239 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
240 time_la_LIBADD): ...so that these are picked up as a deplib of
241 libm4 and don't need to be set explicitly.
243 2003-11-18 Gary V. Vaughan <gary@gnu.org>
245 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
246 from the standard build. It is too fragile.
248 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
249 CVS libtool after merging m4 changes across to libtool.
251 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
252 * m4/path.c (search_path_add): Ditto.
254 2003-11-13 Gary V. Vaughan <gary@gnu.org>
256 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
257 libtool tags we don't use in configure. This reduces the size
258 of the script from over 1Mb to under 700Kb.
260 2003-11-13 Gary V. Vaughan <gary@gnu.org>
262 The import script was not written properly, and the last gnulib
263 import was incomplete. Fixed that problem, and reimport our
264 gnulib dependencies, which picks up the address calculation
265 overflow checks described by Paul below. Also tweak the clients
266 of the gnulib xalloc module not to use deprecated macros:
268 * gnulib/import: Recurse through module dependencies rather than
269 naively descending only one level.
270 * configure.ac: Add calls to gnulib's strnlen and extension module
272 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
274 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
275 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
276 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
277 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
279 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
280 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
281 place of `xcalloc (1, S)'.
282 * m4/m4.c (m4_create): Likewise.
283 * m4/m4private.h (m4_symbol_value_create): Likewise.
284 * m4/symtab.c (symtab_fetch): Likewise.
285 * m4/syntax.c (m4_syntax_create): Likewise.
286 * src/freeze.c (reload_frozen_state): Likewise.
287 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
289 * m4/symtab.c (m4_symtab_create): Likewise.
291 2003-11-13 Gary V. Vaughan <gary@gnu.org>
293 * tests/module.at: Comment typo.
295 2003-10-10 Gary V. Vaughan <gary@gnu.org>
297 * tests/modules.at (modules: importing): Apply some lateral
298 thinking, and use AT_CHECK to compare the output of a sed pass
299 over stderr against the canonical strerror string.
301 * tests/modules.at (modules: importing): Edit the generated stderr
302 output to canonicalize strerror output, before a comparison.
304 2003-10-10 Gary V. Vaughan <gary@gnu.org>
306 Tru64UNIX perl is sloppy with namespace pollution. This patch is
307 careful not to trip over the mess:
309 * modules/perl.c: Some builds of perl install headers that contain
310 `#define try __builtin_try'. Be sure to undefine that macro
311 before `m4/hash.h' gets included, which uses the `try' symbol.
312 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
313 `false' before including `stdbool.h'.
314 (DELETE): This symbol is not in m4's namespace, and is in any
315 case only used internally...
316 * m4/m4private.h (DELETE): ...so move it to here.
317 Reported by Martin MOKREJS <mmokrejs@natur.cuni.cz>
319 2003-10-08 Paul Eggert <eggert@twinsun.com>
321 Don't use XMALLOC and XCALLOC. Once we install the
322 corresponding patch into gnulib, this will fix some
323 address-calculation overflow bugs on hosts where calloc (A, B)
324 returns garbage when A*B overflows.
326 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
327 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
328 xmalloc, XCALLOC with xcalloc.
329 * m4/m4.c (m4_create): Likewise.
330 * m4/m4private.h (m4_symbol_value_create): Likewise.
331 * m4/output.c (m4_output_init): Likewise.
332 * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise.
333 * m4/syntax.c (remove_syntax_attribute): Likewise.
334 * src/freeze.c (reload_frozen_state): Likewise.
335 * src/main.c (main): Likewise.
337 2003-10-07 Gary V. Vaughan <gary@gnu.org>
339 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
340 gnulib/acm4 directories for aclocal m4 macros.
341 * gnulib/Makefile.am (EXTRA_DIST): Removed.
342 (MAINTAINERCLEANFILES): Add Makefile.in.
343 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
345 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
346 * gnulib/import: New file. Temporary script for updating gnulib
347 imported files, until gnulib-tool is working.
348 * gnulib/config/codeset.m4, gnulib/config/error.m4,

386 gnulib/acm4/xstrndup.m4: Reimported from CVS gnulib with
387 gnulib/import script.
388 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/error.c,

392 gnulib/m4/version-etc.c, gnulib/m4/version-etc.h,
393 gnulib/m4/xalloc.h, gnulib/m4/xmalloc.c: Updated from CVS
394 gnulib with gnulib/import script.
395 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
396 guards ready for gnulib-tool to autoupdate on import.

405 * m4/hash.c, m4/m4.c, m4/macro.c, m4/module.c, m4/output.c,
406 m4/path.c, m4/symtab.c, m4/syntax, m4/system_.h, modules/m4.c,
407 src/main.c, src/stackovf.c: s/xfree/free/g to comply with new
409 * src/main.c (version_etc_copyright): Only output the current
411 (version_etc): Call with new variadic API.
413 2003-09-16 Gary V. Vaughan <gary@gnu.org>
415 * gnulib/m4/version-etc.c, gnulib/m4/version-etc.h: Import
416 version-etc module from CVS gnulib.
417 * po/POTFILES.in: Add gnulib/m4/version-etc.c.
418 * src/Makefile.am: Build it.
419 * src/main.c: Use it.
421 * gnulib/m4/exit.h: Import exit module from CVS gnulib.
422 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
423 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
426 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
427 Gary V. Vaughan <gary@gnu.org>
429 * bootstrap: Separate options.
430 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
431 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
433 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
434 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
435 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
436 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
437 $(LTLIBINTL) for gettext support on cygwin.
438 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
439 have $(LTLIBINTL) from the preloaded module la files.
440 * README: Remove the warning about using --disable-nls on Windows
443 2003-09-15 Gary V. Vaughan <gary@gnu.org>
445 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
446 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
449 2003-09-12 Gary V. Vaughan <gary@gnu.org>
451 * doc/STYLE: Document the gnulib header naming conventions, and
453 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
454 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,
455 gnulib/m4/gettext.h, gnulib/m4/obstack.h, gnulib/m4/regex.h
457 * gnulib/m4/Makefile.am: Remove the rules to build these headers.
459 * gnulib/m4/strtol.c, gnulib/config/strtol.m4: Import strtol
460 module from CVS gnulib.
461 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
462 (gl_FUNC_STRTOL): In favour of the module macro.
464 2003-09-12 Gary V. Vaughan <gary@gnu.org>
466 Replace the getopt code with CVS gnulib getopt. The source files
467 detect whether they are in a glibc environment and preprocess away
468 all of the code if there is a system getopt, so we can compile
469 them into the m4 executable unconditionally:
471 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
472 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
473 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
475 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
477 * src/Makefile.am: Adjust.
478 * src/main.c: Always include our shipped getopt.h.
479 * po/POTFILES.in: Use new location of getopt.c.
481 2003-09-12 Gary V. Vaughan <gary@gnu.org>
483 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
484 * config/Makefile.am: Removed. Automake 1.8 distributes the files
485 in this directory automatically.
486 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
488 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
490 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
492 * modules/Makefile.am (pkglibexecdir): Set it here.
493 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
495 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
496 Import regex module from CVS gnulib.
497 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
498 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
499 do extra substitutions for Makefile.
500 * configure.ac: Use it.
501 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
502 from regex_.h if necessary.
503 * m4/system_.h: Include the correct version of regex.h.
504 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
506 * po/POTFILES.in: Use new location of regex.c.
508 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
509 realloc.c: automake distributes these files already.
511 2003-09-12 Gary V. Vaughan <gary@gnu.org>
513 Replace the xstrzdup code by importing the xstrndup module from
514 CVS gnulib, along with its dependencies: strndup and strnlen:
516 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
517 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
519 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
520 gnulib/config/strndup.m4: Ditto wrt strndup.
521 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
523 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
524 However, contrary to gnulib, we install xstrndup.h.
525 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
526 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
527 is an artifact of the old m4 portability layer.
528 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
529 * m4/system_.h: Include xstrndup.h.
530 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
532 2003-09-11 Gary V. Vaughan <gary@gnu.org>
534 Reimport the latest xalloc module from CVS gnulib, and adjust the
535 m4 sources to take advantage of xalloc xfree. Also create a new
536 macro DELETE with the same semantics as the old m4 XFREE macro,
537 and carefully tweak callers:
539 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
541 * m4/utility.c (xfree): Removed. This function is now supplied by
543 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
544 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
545 * m4/symtab.c (m4_symtab_create): Ditto.
546 * m4/system_.h: Removed XFREE redefine.
547 (DELETE): New macro with same functionality as the original m4
548 XFREE macro, but based on xalloc.h now. Changed all callers.
549 * src/main.c (main): Use XMALLOC macro.
550 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
552 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
554 2003-09-10 Gary V. Vaughan <gary@gnu.org>
556 Import the xalloc module from CVS gnulib, along with its
557 dependencies: exitfail, malloc and realloc. We had different
558 semantics for our XFREE and a function xfree() not supplied by
559 gnulib, so also a bit of work to keep everything running
562 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
563 (gl_XALLOC): Use gnulib equivalents.
564 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
565 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
566 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
567 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
569 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
570 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
571 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
573 (pkgincdir): Removed. Use pkgincludedir instead.
574 * m4/m4private.h (XFREE): xfree already checks for NULL.
575 * m4/system_.h: Use xalloc module, and remove macros already
576 supplied by xalloc.h.
577 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
578 moved the old definition from m4/xmalloc.c to here for now.
580 2003-09-09 Gary V. Vaughan <gary@gnu.org>
582 Import the error and progname modules from CVS gnulib. Our old
583 error.c subsumed the functionality of both, so a little adjustment
584 was required to accomodate the split in sources. Also added more
585 wrapper macros to choose between a system installed error.h or our
586 shipped gnulib error module:
588 * m4/error.c, m4/error.h: Removed.
589 * m4/Makefile.am: Adjust.
590 (pkgincdir): Removed. Use pkgincludedir instead.
591 * m4/module.h, src/main.c: Don't include `m4/error.h'.
592 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
594 * gnulib/m4/progname.c: Imported from CVS gnulib.
595 * gnulib/m4/progname.h: Ditto.
596 * src/main.c: Adjust to use progname module.
597 * gnulib/m4/error.c: Imported from CVS gnulib.
598 * gnulib/m4/error_.h: Ditto.
599 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
600 if appropriate, and link a local error.h if the system version is
602 (libgnu_la_SOURCES) Add progname module sources.
603 * gnulib/config/error.m4: Imported from CVS gnulib.
604 * gnulib/config/strerror_r.m4: Ditto.
605 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
606 to have ERROR_H for Makefile substitutions and tell system.h
607 whether the system error.h should be used, or a locally installed
609 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
611 2003-09-09 Gary V. Vaughan <gary@gnu.org>
613 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
614 s/gettext_.h/gettext.h/.
616 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
617 automake have been fixed.
619 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
620 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
621 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
622 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
624 2003-09-09 Gary V. Vaughan <gary@gnu.org>
626 The gnulib obstack module requires the gnulib gettext module for
627 systems that do not have GNU gettext installed. Because we use
628 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
629 that directory incase it clashes with the system gettext.h. This
630 delta uses gettext_.h and extra rules in the Makefile to make a
631 link to gettext.h when needed:
633 * Makefile.am (auxdir): Removed. No longer used.
634 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
635 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
637 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
638 Makefile based build.
639 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
640 of the macros are kept.
641 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
642 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
643 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
644 distributes these automatically.
645 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
646 warning from automake-1.7a.
647 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
648 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
650 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
651 wrt. m4_FUNC_OBSTACK.
652 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
653 wrt. m4_sys_STACKOVF.
654 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
655 wrt. _m4_LIB_GMP, m4_LIB_GMP.
656 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
657 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
659 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
660 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
661 gettext.h link on deficient systems.
662 (pkginc_HEADERS): Mention $(GETTEXT_H).
663 (EXTRA_HEADERS): Mention gettext.h.
664 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
665 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
666 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
667 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
668 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
669 gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
670 gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
671 gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
672 gnulib/config/po.m4, gnulib/config/progtest.m4,
673 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
674 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
676 2003-09-05 Gary V. Vaughan <gary@gnu.org>
678 We can't mirror the gnulib directory structure here, since we need
679 to be able to eg. `#include <m4/obstack.h>' from our source files,
680 which is much easier if the local obstack.h is created in a
681 directory named m4. Rather than trying to symlink everything into
682 the m4 directory, now we build a libtool convenience library from
683 the sources we get from gnulib and link that with libm4.la:
685 * gnulib/config/extensions.m4: Imported from CVS gnulib.
686 * gnulib/config/unlocked-io.m4: Ditto.
687 * gnulib/m4/unlocked-io.h: Ditto.
688 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
689 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
690 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
691 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
692 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
693 * m4/Makefile.am: Adjust.
694 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
695 macros we redistribute.
696 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
697 library among others.
698 (GNULIB_SRCS, GNULIB_MACROS): Removed.
699 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
700 * config/m4-obstack.m4: Adjust.
701 * po/POTFILES.in: Adjust.
702 * configure.ac: Reformatting. Call newly imported gnulib macros.
703 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
704 bogus calls of `#include "m4.h"'.
705 * Makefile.am: INCLUDES has been deprecated in favour of
707 * m4/Makefile.am: Ditto.
708 * modules/Makefile.am: Ditto.
709 * src/Makefile.am: Ditto.
711 2003-09-05 Gary V. Vaughan <gary@gnu.org>
713 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
715 2003-09-04 Gary V. Vaughan <gary@gnu.org>
717 Migrate the obstack support into the gnulib directories for easy
718 synchronisation with upstream files in gnulib:
720 * config/gnu-obstack.m4: Moved from here...
721 * config/m4-obstack.m4: ...to here.
722 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
723 * m4/obstack.c, m4/obstack_.h: Moved from here...
724 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
725 * po/POTFILES.in: Adjust.
726 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
727 * m4/Makefile.am: Add a whole new section to link the obstack
728 sources from the gnulib tree if necessary.
729 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
731 * config/m4-obstack.m4: Rewrite as a wrapper for
732 gnulib/m4/obstack.m4.
734 2003-09-04 Gary V. Vaughan <gary@gnu.org>
736 GNU M4 currently builds with a number of files adapted from
737 upstream sources. Recently the gnulib project on savannah.gnu.org
738 has pulled together a great many of these externally maintained
739 files. This delta is the beginnings of isolating those files
740 maintained in gnulib to make it easy to synchronise M4 with the
741 upstream files prior to releases.
743 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
745 (SUBDIRS): Added new gnulib subdirectory.
746 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
747 * config/stdbool.m4: Moved from here...
748 * gnulib/m4/stdbool.m4: ...to here.
749 * m4/stdbool_.h: Moved from here...
750 * gnulib/lib/stdbool_.h: ...to here.
751 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
753 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
754 code to work with new stdbool_.h location.
755 (gnulib_srcdir): New.
757 2003-09-04 Gary V. Vaughan <gary@gnu.org>
759 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
760 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
762 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
763 (EXTRA_DIST): Use it.
765 * bootstrap: CVS autoreconf leaves file droppings. Remove
766 aclocal.m4t incase autoreconf doesn't.
768 2003-08-29 Gary V. Vaughan <gary@gnu.org>
770 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
771 the other gnulib imports, renamed to m4/obstack_.h.
772 * m4/obstack.c: Updated from CVS gnulib.
773 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
774 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
775 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
776 about vpath already, and $top_srcdir upsets CVS Automake, so the
777 $top_srcdir reference was removed.
779 * m4/system-h.in: For consistency with the gnulib imports, renamed
781 * m4/Makefile (EXTRA_HEADERS): Adjust.
782 * configure.ac (AC_CONFIG_FILES): Adjust.
784 * m4/stdbool_.h: New file from gnulib for systems without their
786 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
787 * config/stdbool.m4: New file. Macros from gnulib for same.
788 * configure.ac: Use it.
790 2003-08-27 Gary V. Vaughan <gary@gnu.org>
792 * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'`
793 * config/gmp.m4: Ditto.
794 * config/gnu-obstack.m4: Ditto.
795 * config/stackovf.m4: Ditto.

837 * src/getopt1.c: Ditto.
840 * src/stackovf.c: Ditto.
842 * config/gmp.m4 (M4_AC_LIB_GMP): Use AC_INCLUDES_DEFAULT:
843 ac_default_headers is an autoconf internal variable.
844 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
845 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
847 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
848 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
851 2003-08-15 Gary V. Vaughan <gary@gnu.org>
853 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
855 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
856 possible or faking one with a typedef. Changed all callers.
858 2003-08-15 Gary V. Vaughan <gary@gnu.org>
860 Still cleaning up the users' module API, by taking out the stuff
861 that isn't used by any existing modules, and moving specialised
862 functions out of libm4 and into the module they are used by.
864 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
865 * m4/utility.c (m4_skip_space): ...to here the home of its only
866 use, made static and renamed to `skip_space'. Changed all
868 * m4/m4module.h (m4_expand_ranges): Removed prototype.
869 * m4/utility.c (m4_expand_ranges): Moved definition from here...
870 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
872 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
874 * modules/gnu.c (builtin_syntax): Import and use in this
875 builtin implementation.
876 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
878 * m4/macro.c (trace_flush): Except here where the macro is now
880 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
881 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
883 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
884 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
886 2003-08-14 Gary V. Vaughan <gary@gnu.org>
888 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
889 compiler based AC_CHECK_HEADER that was introduced in
891 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
892 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
893 * configure.ac: Use renamed M4_AC_LIB_GMP.
895 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
896 macro that requires arguments! This stops the shell's bad
897 substitution error at configure time.
899 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
900 variables to the testsuite shell. Set the value of USE_GMP so
901 that the gmp test will run!
902 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
904 2003-08-11 Gary V. Vaughan <gary@gnu.org>
906 Libltdl already has an excellent mechanism for accessing C symbols
907 in modules. Lets use that! Remove all the exporting cruft and
908 just use lt_dlsym in conjunction with a few conventions to
909 simplify module writers' jobs. Also removed the table address
910 caching code and otherwise simplified the module loader quite a
911 bit. To access exported symbols in other modules, first the
912 exporting module must name the symbols <modname>_LTX_<symname>,
913 and the importing module must define a function type called
914 <symname>_func. The importer then adds
915 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
916 that wishes to call out to the exported functions. Care must be
917 taken that <symname> is non-NULL in the importing module incase
918 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
919 definition was in the importers source. Study
920 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
921 m4_module_import will attempt to automatically load a module
922 required for symbol access if it is not loaded already.
924 * TODO: Removed the items fixed in this delta.
925 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
927 * m4/ltdl.h (lt_dlhandle_find): Declare it.
928 * m4/module.c (m4_module_unload): Use it.
929 * src/freeze.c (reload_frozen_state): Ditto.
930 * m4/m4module.h (m4_export): Deleted. Removed all references.
931 (M4_MODULE_IMPORT): New user convenience macro for importing
932 arbitrary symbols from other modules.
933 * m4/module.c (m4_module_import): New function to service
934 M4_MODULE_IMPORT macro.
935 (module_data): Removed. Looking up the tables on demand with
936 lt_dlsym, rather than caching their addresses here simplifies the
938 (m4_get_module_builtin_table, m4_get_module_macro_table):
939 Removed. Changed all callers.
940 (set_module_macro_table, set_module_builtin_table): Renamed to
941 install_macro_table and install_builtin_table respectively, and
942 simplified now that the cache is no more.
943 * modules/gnu.c (builtin_symbols): Use this new mechanism to
944 import m4_dump_symbols from the m4 module.
945 (builtin_esyscmd): Likewise for m4_set_sysval and
947 * modules/m4.c (m4_export_table): Removed. Functions are
948 addressed with the new mechanism which doesn't need this.
949 (m4_set_sysval): New exported accessor function to prevent
950 problems with variable access on inferior architectures.
951 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
952 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
953 that we can have some type safety.
954 * modules/modtest.c (export_test): C level exported function for
955 testing the new import mechanism.
956 * modules/import.c: New file for the import end of the test.
957 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
958 * tests/modules.at: New test cases for intermodule symbol
961 2003-08-07 Gary V. Vaughan <gary@gnu.org>
963 * m4/m4module.c (m4_string): Moved from here...
964 * m4/m4private.c (m4_string): ...to here.
966 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
968 2003-07-29 Gary V. Vaughan <gary@gnu.org>
970 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
971 already available to module writers through
972 m4_{get,set}_nesting_limit_opt(), so moved from here...
973 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
976 2003-07-28 Gary V. Vaughan <gary@gnu.org>
978 Aside from auditing path.c for m4module.h api obfuscation, this
979 delta introduces the concept of private struct members in opaque
980 data types to GNU m4: See the STYLE file for details.
982 * TODO: Remind ourselves that a rewrite of path.c is needed.
983 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
985 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
986 here and renamed. These type definitions are for internal api use
987 only. Changed all callers.
988 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
990 * m4/path.c (search_path_env_init, search_path_add): ...to here
991 and renamed. These calls were never used outside this file.
993 (dirpath): Moved functionality of this static declaration...
994 * m4/m4private.h (struct m4): ...to this new internal only
995 search_path field. Changed all callers.
996 (m4__get_search_path): Added new internal api accessor.
997 * m4/path.c (m4_search_path_info_new): Removed. Not used.
998 (m4_include_init): Removed...
999 * m4/m4.c (m4_create): ...because the new m4 field is now
1001 (m4_delete): Recycle search_path memory.
1002 * src/main.c (main): Don't call m4_include_init now that it's
1004 * doc/STYLE: Document convention for private fields in opaque
1007 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1009 Sometimes exporting the address of a symbol from a module isn't
1010 enough for other modules to call that symbol correctly. If
1011 custom data types are used for function parameters, they need to
1012 be known to the caller. This change introduces the concept of
1013 $(prefix)/include/modules/$(modulename).h to declare those
1014 structures. Also we move m4_dump_symbols from libm4 to the m4
1015 module to show this concept in action.
1017 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
1018 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
1019 exporting data structures from modules/m4.c.
1020 * modules/m4.c, modules/gnu.c: Include it.
1021 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
1022 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
1024 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
1026 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
1027 ...to here, with slight renaming.
1028 (m4_export_table): Prototype and add m4_dump_symbols.
1029 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
1030 definition of m4_dump_symbols.
1031 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
1032 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
1034 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1036 Create an export table in modules/m4.c in readiness for beefing up
1037 the module loader to track module exports and imports.
1039 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
1040 * m4/debug.c (m4_debug_flush_files): Moved...
1041 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
1042 * modules/gnu.c (builtin_esysval): Use it.
1043 * m4/m4module.h (m4_export): New type for declaring module symbols
1045 * modules/m4.c (m4_export_table): List symbols exported from this
1046 module for use by other modules.
1048 2003-07-24 Gary V. Vaughan <gary@gnu.org>
1050 An experiment: There is loads of code in libm4 which should be in
1051 the m4 module, but is also used by another module. Just because
1052 some linkers won't cope with calls across dynamic runtime loaded
1053 objects I initially left the code in libm4. It will tidy the
1054 module api immensely if this code moves to the right place, I just
1055 need to remember to invent a suitable calling mechanism at some
1056 point. For now, only modules that are statically linked and
1057 preloaded will get this treatment, so the only platforms that will
1058 break are those that require all symbols to be resolved at link
1061 * TODO: Reminder that what I am doing could reduce portability
1062 unless I do something more robust later.
1063 * m4/m4module.h (m4_sysval): No longer exported from libm4.
1064 * m4/utility.c (m4_sysval): No longer declared in libm4.
1065 * modules/Makefile.am: Reformatting.
1066 * modules/m4.c (m4_sysval): Declare it at place of use.
1067 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
1069 2003-07-23 Gary V. Vaughan <gary@gnu.org>
1071 * m4/m4module.h: Reformatting and rearranging lines a bit.
1072 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
1074 (m4_call_macro, m4_expand_input): Renamed...
1075 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
1077 (m4_expansion_level, m4_process_macro): Moved...
1078 * m4/macro.c (expansion_level, process_macro): ...to here, and
1081 * m4/m4module.h (program_name): Not used by modules at all, so
1083 * src/main.c (program_name): ...to here.
1084 (print_program_name): Renamed...
1085 (print_program_name_CB): ...to conform to the STYLE guide.
1087 2003-07-23 Gary V. Vaughan <gary@gnu.org>
1089 More refactoring of the m4module.h API. Replace #defines with an
1090 enum, and move non-public functions out of the public API.
1092 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
1094 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
1095 * m4/debug.c (m4_debug, trace): Moved...
1096 * m4/m4private.h (struct m4): ...to fields of this struct.
1097 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
1099 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
1100 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
1101 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
1102 * m4/m4module.h (m4_context_field_table): Add entries for new
1103 debug_file and trace_messages fields.
1104 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
1105 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
1106 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
1107 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
1108 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
1109 (m4_is_debug_bit): New macro to simplfy checks against the debug
1111 (m4_trace_format, m4_trace_header, m4_trace_flush)
1112 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
1114 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
1115 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
1116 * m4/macro.c (trace_format, trace_header, trace_flush)
1117 (trace_prepre, trace_pre, trace_post): ...to these newly static
1118 functions, since they are only ever used from this file. Changed
1121 2003-07-17 Gary V. Vaughan <gary@gnu.org>
1123 Change the macros for checking syntax so that matching against
1124 multiple possible syntax classes can be done with a single
1125 comparison some of the time. The various classes are now bits of
1126 an int that can be checked with bitwise logic operators.
1128 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
1129 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
1130 (M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)
1131 (M4_SYNTAX_ASSIGN, M4_SYNTAX_ALPHA, M4_SYNTAX_NUM)
1132 (M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)
1133 (M4_SYNTAX_ECOMM): Replaced #defines with an enum.
1134 (M4_SYNTAX_ALNUM): Removed. Changed all callers.
1135 (M4_IS_IGNORE, M4_IS_OTHER, M4_IS_SPACE, M4_IS_OPEN, M4_IS_CLOSE)
1136 (M4_IS_COMMA, M4_IS_DOLLAR, M4_IS_ACTIVE, M4_IS_ESCAPE)
1137 (M4_IS_ASSIGN, M4_IS_ALPHA, M4_IS_NUM, M4_IS_LQUOTE, M4_IS_RQUOTE)
1138 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
1139 Replace all calls with invocations of these...
1140 (m4_is_syntax, m4_has_syntax): ...New macros.
1141 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
1142 is no longer required with new macros. Changed all callers.
1144 2003-07-15 Gary V. Vaughan <gary@gnu.org>
1146 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
1147 values are returned as part of the internal interface, so they
1149 * m4/private.h: ...to here.
1150 * m4/macro.c (expand_token): Check for out of range
1151 m4_peek_input() results before looking up in the syntax table.
1152 (collect_arguments): Ditto.
1154 * NEWS: Note `$' syntax class.
1156 2003-07-08 Paul Eggert <eggert@twinsun.com> and
1157 Gary V. Vaughan <gary@gnu.org>
1159 Conform to POSIX if the POSIXLY_CORRECT environment is set.
1160 --traditional `define' now smashes all the definitions.
1162 * NEWS: Explain this.
1163 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
1164 (Extensions): Explain that extensions that are incompatible with
1165 POSIX are disabled if POSIXLY_CORRECT is set.
1166 (Incompatibilities): Remove.
1167 (Define, Other Incompat): Explain difference
1168 between GNU and POSIX behavior of define, pushdef, popdef.
1169 * m4/m4.c (m4_get_posixly_correct_opt): New undef.
1170 * m4/m4module.h (m4_context_opt_bit_table): Add POSIXLY_CORRECT entry.
1171 * m4/m4private.h (M4_OPT_POSIXLY_CORRECT_BIT): New macro.
1172 (m4_get_posixly_correct_opt): New macro.
1173 * m4/m4macro.c (m4_process_macro): Disable $10, $abc etc. if
1175 * modules/m4.c (builtin_functions): defn now takes any number of args.
1176 (builtin_define): Smash all the definitions if
1178 (builtin_defn)): Allow any number of arguments.
1179 (builtin_undivert): Do not allow nonnumeric arguments
1181 * src/main.c (main): Set posixly-correct behavior if either
1182 POSIXLY_CORRECT is set, or if -G is given.
1183 * tests/builtins.at: New test for smashed definitions.
1185 2003-06-27 Gary V. Vaughan <gary@gnu.org>
1187 * doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
1188 * m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
1189 not to slow the parser down.
1190 (M4__IS_STRING): New macro to test string syntax class membership.
1191 * m4/syntax.c: Adjust docucomment.
1192 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
1193 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
1194 * m4/input.c (init_builtin_token): Comment typo.
1195 (m4__next_token): Comment typo.
1196 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
1197 by using the new M4__IS_STRING macro.
1198 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
1199 variable references in macro expansions.
1201 * doc/m4.texinfo (Eregexp and Regexp): Typo.
1202 (Epatsubst and Patsubst): Typo.
1205 2003-06-26 Gary V. Vaughan <gary@gnu.org>
1207 Move the global variables that pertain to syntax to a new `struct
1208 m4_syntax_table', and then add one of these to `struct m4'. The
1209 ripple effect through the code to both change formerly global
1210 references, and make sure a suitable context is available in
1211 lexical scope is disproportionately large compared to the size of
1212 the change proper. This change is a large part of decoupling
1213 syntax.c from the rest of the code that uses it.
1215 * m4/m4private.h (struct m4): Add a syntax field.
1216 * m4/m4.c (m4_create): Initialise it,
1217 (m4_delete): Recycle it.
1218 (m4_get_symtab): Remove hand coded version...
1219 (m4_get_symbol_table): ...and generate this with cpp. Changed all
1221 * m4/m4module.h (m4_context_field_table): Add an extra field so we
1222 can generate m4_get_symbol_table. Add a new row for
1223 m4_get_syntax_table.
1224 (M4SYNTAX): Syntactic sugar for module writers.
1225 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
1226 (m4_syntax_table): New home for syntax related formerly global
1228 * m4/m4private.h (struct m4_syntax_table): Define it.
1229 * m4/input.c (m4_input_init): Initialisation of these formerly
1230 global variables moved...
1231 * m4/syntax.c (m4_syntax_create): ...to here.
1232 * m4/input.c (m4_input_exit): And similarly, recycling of the
1233 memory used by those values moved...
1234 * m4/syntax.c (m4_syntax_delete): ...to here.
1235 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
1236 Moved to m4/m4private.h.
1237 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
1238 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
1239 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
1240 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
1241 objects. Changed all callers that used to directly access the
1243 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
1244 Removed and incorporated into m4_syntax_table structure.
1245 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
1246 * m4/syntax.c (m4_set_syntax): Now returns an error status,
1247 instead of requiring a `struct m4' to generate its own errors.
1248 Changed all callers.
1249 * src/main.c (main): Now that the syntax table is initialised as
1250 part of m4_create, we have to manually wipe the syntax entries if
1251 we are about to read a frozen file.
1253 2003-06-26 Gary V. Vaughan <gary@gnu.org>
1255 * doc/STYLE: Added notes on callback naming schemes.
1257 * m4/module.c (m4_set_module_macro_table)
1258 (m4_set_module_builtin_table): Declarations weren't changed when
1259 definitions were renamed on 2003-06-19.
1261 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
1262 neither used nor particularly appropriate since it exposes the
1263 internal workings of the hash module. I haven't yet decided
1264 whether to remove it entirely.
1266 2003-06-20 Gary V. Vaughan <gary@gnu.org>
1268 Two related changes, and a huge knockon effect throughout the
1269 source: Moved the option variables out of global space and into
1270 `struct m4'; made `m4_symtab' a real datatype, so that its api
1271 is not marred passing `struct m4' around just so it can decide
1272 whether to keep traced symbol names or not. Added setters and
1273 getters for the formerly global option variables, and obviously
1274 changed a vast number of functions to take a `struct m4' and use
1275 the getter funcs to find option values.
1277 * m4/utility.c (interactive, sync_output, debug_level)
1278 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
1279 (max_debug_argument_length, warning_status, nesting_limit)
1280 (discard_comments): Removed.
1281 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
1282 (debug_level, max_debug_argument_length, prefix_all_builtins)
1283 (suppress_warnings, discard_comments, interactive, sync_output):
1284 Removed from here...
1285 * m4/m4private.h (struct m4): ...and equivalent fields added to
1287 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
1288 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
1289 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
1290 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
1291 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
1292 macros for the new fields.
1293 * m4/m4module.h (m4_context_field_table)
1294 (m4_context_opt_bit_table): Helper macros used to generate
1295 prototypes, setters and getters for new option fields
1297 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)

1305 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
1306 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
1307 setter and getter functions generated by cpp from
1308 m4_context_field_table and m4_context_opt_bit_table, exported as
1309 part of the module api. Changed all callers.
1310 * m4/symtab (struct m4_symtab): Used as the concrete type for
1312 (m4_symtab_create): Allocate and initialise a new struct.
1313 (m4_symtab_apply): New function that works like m4_hash_apply, but
1314 with different callbacks specific to symbol tables. Changed all
1316 (symbol_destroy, arg_destroy, arg_copy): Renamed
1317 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
1318 they have unused parameters for a reason!
1319 (dump_symbol_CB): New callback to dump the contents of a single
1321 (symtob_dump): Rewritten in terms of dump_symbol_CB.
1322 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
1323 Changed all callers.
1324 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
1325 of the contained `m4_symtab' at the `no_gnu_extensions' field.
1326 Although I'm not convinced these semantics are correct, they are
1327 at least consistent with how things were before this delta. Also
1328 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
1330 2003-06-19 Gary V. Vaughan <gary@gnu.org>
1332 Tie down the interface to libm4 some more. Make more structures
1333 opaque to modules by moving them to m4private.h, and writing
1334 setters and getters. To win back the speed penalty for doing this
1335 also wrote macroized versions that do know about structure layout
1336 in m4private.h and #include that file into modules when NDEBUG is
1337 defined at compile time. There are still some accessor macros in
1338 m4private.h that need to go, but that is not necessary to clean
1341 * m4/m4module.h (m4_symbol_type): Moved...
1342 * m4/m4private.h (m4__symbol_type): ...to here.
1343 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
1344 (m4_set_symbol_traced, m4_set_symbol_name_traced)
1345 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
1346 (m4_get_symbol_func, m4_symbol_value_create)
1347 (m4_symbol_value_delete, m4_set_symbol_value_text)
1348 (m4_set_symbol_value_func): New exported api to symbols.
1349 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
1350 and m4_is_symbol_value_func.
1351 * m4/m4module.h: Prototype these guys.
1352 * m4/module.c (m4_set_module_macro_table)
1353 (m4_set_module_builtin_table): Make these static, there is no
1354 reason to pollute the api with them.
1355 * m4/m4private.h: Reformatting.
1356 (m4_get_symtab): Only define when NDEBUG is defined.
1357 (m4_get_symbol_value, m4_get_symbol_traced)
1358 (m4_set_symbol_traced, m4_set_symbol_name_traced)

1361 (m4_symbol_value_delete, m4_set_symbol_value_text)
1362 (m4_set_symbol_value_func): Macro implementations of the new
1363 functions when NDEBUG is defined.
1364 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
1365 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
1366 Superceded by the above. All callers changed.
1367 (M4ARG): Removed. This is no longer different to the
1368 m4/m4module.h definition.
1369 * modules/gnu.c, modules/m4.c: Only include m4private.h when
1370 NDEBUG is defined. That way we exercise the same (albeit slower)
1371 api that external modules must use.
1373 2003-06-18 Gary V. Vaughan <gary@gnu.org>
1375 Renamed some of the types and their accessors to make more sense.
1376 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
1377 has a stack of SYMBOL_VALUEs.
1379 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
1380 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
1381 m4_get_symbol_value_type, m4_get_symbol_value_text,
1382 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
1383 Changed all callers.
1384 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
1385 (m4_get_token_type): Renamed
1386 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
1387 to the internal api.
1388 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
1390 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
1391 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
1392 (m4__token_type): Moved here from m4module.h.
1393 (m4__next_token): Renamed from m4_next_token.
1394 * m4/symtab.c: Removed some of the parameterised macro support
1395 functions for modularisation later.
1396 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
1397 m4_hash_dup to perform a true deep copy of the SRC.
1398 (arg_copy): Callback for m4_symbol_value_copy.
1399 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
1400 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
1401 m4_get_symbol_value_func. Changed all callers.
1403 2003-06-18 Gary V. Vaughan <gary@gnu.org>
1405 Tidy up style of hash.[ch] in accordance with doc/STYLE.
1407 * m4/hash.c: Internal symbol renaming and formatting.
1408 (m4_hash_dup): New function to facilitate deep copies of hash
1410 (m4_hash_apply_func): Returns a void* now, which is a richer type
1411 for returning exceptions (NULL means keep going).
1412 (m4_hash_apply): Ditto.
1413 * m4/hash.h: Declare exported symbols with an explicit extern.
1416 2003-06-17 Gary V. Vaughan <gary@gnu.org>
1418 Still refactoring furiously. This delta represents a change in
1419 semantics to symtab.c. Instead of building temporary m4_tokens
1420 in the caller, and copying fields in the methods, we now create
1421 the actual m4_token for hashing in the caller so the methods just
1422 slot them in directly. Also, this means that we don't lookup a
1423 symbol and get back an allocated but VOID token to copy fields
1424 into, we create the token we want to push and pass that to
1425 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
1426 a few other small changes to stop knowledge of the implementation
1427 of symtab.c leaking out into other files.
1429 * m4/macro.c (expand_argument): Comment typo corrected.
1430 * m4/symtab.c (symtab_fetch): New function to fetch the address of
1432 (m4_symbol_pushdef): Take an extra value parameter and use this
1433 directly as the new top of the value stack. All callers changed
1434 to build a token and pass responsibility for memory in, rather
1435 than copying as we used to.
1436 (m4_symbol_define): Also use the new value parameter directly as a
1437 replacement for the top of the value stack. All callers changed
1438 to build a token as above.
1439 (m4_set_symbol_traced): New function to set the traced bit on the
1440 named symbol, creating it if necessary.
1441 (symbol_popval): The guts of the old m4_symbol_popdef.
1442 (m4_symbol_popdef): Use it.
1443 * m4/builtin.c (m4_symbol_set_token): Removed,
1444 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
1446 * m4/module.c (m4_set_module_builtin_table)
1447 (m4_set_module_macro_table): ...with these more orthogonal
1449 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
1450 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
1452 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
1453 (m4_arg_signature_parse): Moved...
1454 * m4/symtab.c: ...to here.
1455 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
1456 screw something up. Moved...
1457 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
1458 actually does a proper deep copy of source to dest.
1460 2003-06-16 Gary V. Vaughan <gary@gnu.org>
1462 Further refactoring to stabilise the module API. Renaming some
1463 functions for orthogonality, and judicious definition migration to
1464 move things out of the set of exported symbols.
1466 * doc/STYLE: New file. Notes on coding style.
1467 * m4/m4module.c: Updated bitrotted docucomment at the top of the
1469 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
1470 m4_get_module_name, m4_get_module_builtin_table,
1471 m4_get_module_macro_table which are verb phrases. Changed all
1473 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
1475 * m4/module.c (m4_set_module_builtin_table)
1476 (m4_set_module_macro_table): ...here, and renamed. Changed all
1478 * m4/m4module.c (m4_module_data): This...
1479 * m4/m4private.c (struct m4_module_data): ...and this...
1480 * m4/module.c (module_data) ...consolidated here and no longer
1481 exported. Changed all callers.
1483 2003-06-16 Gary V. Vaughan <gary@gnu.org>
1485 Begin work on lifting the curse of the global variables. To start
1486 with create a `struct m4' context container, and replace
1487 `m4__symtab' with `context->symtab' throughout. This means
1488 initialising a context container in main, and adjusting many
1489 functions between main and the module entry points so that the
1490 container gets passed through. It would have been nice to
1491 defer this until after 1.5, but it has a major effect on the
1492 user's module writing ABI, so it needs to be addressed now - at
1493 least in the areas that impact the ABI. An interrelated change
1494 in the symtab API removes the dependency on a global symbol table,
1495 and instead focuses on a passed table (from the context
1498 * TODO: Reminders for finishing context functionality.
1499 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
1500 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
1501 global variables and eventually allow m4 to be reentrant.
1502 * m4/m4private.h (m4): Define the new structure here...
1503 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
1504 don't carry the overhead of a function call.
1505 * m4/m4module.h: Prototype extern functions from m4/m4.c.
1506 (m4): Declare type for new struct m4 objects.
1507 (M4SYMTAB): User macro to ease finding the symbol table for the
1508 current context for module developers.
1509 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
1511 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
1512 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
1513 (m4_call_macro, m4_dump_symbols, m4_expand_input)

1515 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
1516 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
1517 m4* context parameter. Changed definitions and all callers.
1518 (m4_symtab): Alias for m4_hash to decouple the
1519 m4_symtab api from m4_hash.
1520 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
1522 (m4_symtab_create): New function to return an initialised
1524 (m4_symtab_delete): New function to delete an m4_symtab's memory.
1525 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
1526 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
1527 instead of simply using the global m4__symtab. Changed
1528 definitions and all callers.
1529 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
1530 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
1531 * src/main.c (main): Create a context and use that instead of the
1532 former global m4__symtab.
1534 2003-06-13 Gary V. Vaughan <gary@gnu.org>
1536 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
1537 to the callback. Callbacks should not need to hardcode the
1538 hashtable they are working from, nor should we have to waste the
1539 userdata parameter to pass the table in.
1540 * m4/hash.h (m4_hash_apply_func): Require the initial table
1542 * m4/symtab.c (symtab_destroy): Use the passed table instead
1543 of hardcoding m4__symtab.
1544 (m4_symbol_popdef): Don't use the userdata parameter to pass the
1545 table to arg_destroy.
1546 (arg_destroy): Use the hash parameter, ignore userdata.
1547 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
1549 (traceon, traceoff): Call set_trace with the extra initial
1552 2003-06-13 Gary V. Vaughan <gary@gnu.org>
1554 More refactoring to stabilise the module api, this time for
1555 symtab.c. Additionally, start to pay attention to function names
1556 that don't contain a verb like they should.
1558 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
1559 wrapper for m4_hash_apply to decouple the symtab module from the
1561 (m4_symbol_builtin, m4_symbol_macro): Renamed to
1562 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
1564 (m4_symbol_delete): Create a macro version to save a function
1566 (m4_token_t, m4_data_t): These violate the POSIX reserved
1567 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
1569 (m4_token_type): Renamed to m4_token_get_type.
1570 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
1571 (m4_symtab_exit): Removed from the exported module
1573 * m4/m4private.h (m4__symtab, m4__symtab_init)
1574 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
1575 renamed and added to the internal api. Changed all callers.
1576 (m4_symtab_apply): A faster macro version of the function for
1577 users of the internal api.
1578 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
1579 symbol_destroy and arg_destroy.
1580 (symtab_debug): Added a prototype.
1581 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
1582 so that callers in this file get the faster macro versions from
1585 2003-06-12 Gary V. Vaughan <gary@gnu.org>
1587 Refactoring modules to rationalise the API into an external
1588 documented (eventually!) API for use by modules in the `m4_'
1589 namespace declared in m4/m4module.h, an internal API between the
1590 source files we ship (including our shipped modules) in the `m4__'
1591 namespace declared in m4/m4private.h and making the rest as
1592 cohesive as possible with liberal use of the `static' keyword.
1593 This change represents an audit to m4/module.c along these
1596 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
1597 Removed. No longer used.
1598 (m4_module_close): Removed prototypes.
1599 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
1600 from the exported module api...
1601 * m4/m4private.h (m4__module_init, m4__module_open)
1602 (m4__module_exit): ...and renamed and added to the internal api.
1603 Changed all callers.
1604 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
1605 Centralised definitions after renaming...
1606 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
1607 (M4_FINISH_SYMBOL): ...and removing from here.
1608 (m4_module_dlerror, m4_module_remove, m4_module_close)
1609 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
1610 module_remove, module_close and caller_id.
1611 (MODULE_SELF_NAME): New macro to make reporting self errors
1613 (m4_module_load, module_close, module_remove): Use it.
1614 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
1616 * src/main.c (main): Use it.
1618 2003-06-12 Gary V. Vaughan <gary@gnu.org>
1620 * README: Remove references to --enable-changeword, which has been
1621 removed from the code.
1623 2003-06-11 Gary V. Vaughan <gary@gnu.org>
1625 Getting rid of the annoying bug with configure --enable-debug,
1626 which spewed -e: command not found errors. This was an interaction
1627 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
1628 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
1629 branch-1-5) to get the full fix.
1631 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
1632 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
1633 and then use the probed value of $SED.
1634 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
1635 this, it messes up the AC_REQUIRE stack.
1637 2003-06-10 Gary V. Vaughan <gary@gnu.org>
1639 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
1640 the destroy callback.
1641 (m4_arg_destroy): Use the hash address to free the hash node key
1644 2003-06-06 Gary V. Vaughan <gary@gnu.org>
1646 First cut at formal parameters in macros.
1648 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
1649 * m4/xstrzdup.c: New file.
1650 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
1651 associative array of parameter names to details.
1652 (m4_symbol_token): Capture macro names with parameter lists.
1653 (m4_arg_signature_parse): And build an associative array to hang
1654 from the symbol structure to map names to details.
1655 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
1656 m4_hash_resize idiom. Now that we potentially add a little hash
1657 table to many of the entries in the symbol table, added an extra
1658 arg to set the initial size. Changed all callers.
1659 (m4_hash_apply): New function that is basically a generalised
1661 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
1662 all callers to call m4_hash_apply instead.
1663 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
1664 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
1665 m4_arg_signature association that might be attached to the symbol,
1666 * m4/hash.h (m4_hash_apply_func): Replacement type for...
1667 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
1668 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
1670 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
1671 (M4_IS_IDENT): Detect characters that can be safely used in
1673 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
1674 * m4/macro.c: Corrected grammar in some comments. Use `token'
1675 rather than `td' for m4_token variables.
1676 (m4_process_macro): If we find a dollar followed by some
1677 M4_IS_IDENT characters, replace that with the contents of the argv
1678 entry with offset stored in the m4_token_arg associated with the
1679 collected identifier.
1681 2003-06-05 Gary V. Vaughan <gary@gnu.org>
1683 Begin preparations for supporting formal parameters in m4 macros.
1685 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
1686 the details of a formal parameter.
1687 (m4_token): Add an arg_signature member to hold a hash table for
1688 looking up formal parameters.
1689 * m4/input.c: Update more bitrotted comments.
1690 (m4_push_builtin): Initialise arg_signature member.
1691 (init_builtin_token): Copy arg_signature member.
1692 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
1693 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
1695 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
1696 (m4_macro_pushdef, m4_macro_define): ...these, And...
1697 (m4_symbol_token): ...wrapped around this new function, which
1698 vastly simplifies the arguments required by the functions it
1700 Changed all callers.
1702 2003-06-05 Gary V. Vaughan <gary@gnu.org>
1704 * m4/macro.c: Format changes.
1706 2003-06-04 Gary V. Vaughan <gary@gnu.org>
1708 * m4/input.c: Updated various bitrotted comments.
1709 (m4_push_builtin): Just pass the whole m4_token, rather than
1710 extracting all the fields in the caller. This also allows us to
1711 check the token type for consistency.
1712 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
1713 Renamed to builtin_funcs, builtin_peek, builtin_read,
1714 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
1715 the code. Changed all callers.
1716 (struct input_block): Similarly renamed u_m member to u_b, and
1717 changed all callers.
1718 (m4_next_token): Use bzero to initialise the data fields.
1719 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
1721 2003-05-29 Gary V. Vaughan <gary@gnu.org>
1723 These changes were necessary to get m4 to build on my iBook
1724 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
1725 (GCC) 3.1 20020420 (prerelease)":
1727 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
1728 inclusion of module loader headers.
1729 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
1730 * m4/Makefile.am: Ditto.
1731 (libm4_la_LIBADD): Added $(LTLIBINTL).
1732 * m4/utility.c (program_name): Removed declaration in favour of
1733 the one already in error.c!
1734 * m4/m4module.h (program_name): Define to program_invocation_name
1735 when using GNU C library. Use an explicit extern declaration.
1736 (interactive, sync_output, debug_level, hash_table_size)
1737 (no_gnu_extensions, prefix_all_builtins, max_debug_argument_length)
1738 (suppress_warnings, warning_status, nesting_limit, discard_comments)
1739 (lquote, rquote, bcomm, ecomm, m4_bad_argc, m4_skip_space)
1740 (m4_numeric_arg, m4_shipout_int, m4_shipout_string, m4_dump_args)
1741 (m4_debug, m4_debug_init, m4_debug_exit, m4_debug_decode)
1742 (m4_debug_flush_files, m4_debug_set_output, m4_debug_message_prefix)
1743 (m4_trace_prepre, m4_trace_pre, m4_trace_post, m4_sysval)
1744 (m4_expansion_level, m4_expand_ranges, m4_expand_input)
1745 (m4_call_macro, m4_process_macro, m4_syntax_table, m4_current_file)
1746 (m4_current_line, m4_current_diversion, m4_output_current_line):
1747 Don't rely on default, use an explicit extern.
1748 * m4/error.h (error, error_at_line, error_print_progname)
1749 (error_message_count, error_one_per_line): Ditto.
1750 * m4/ltdl.c: Update from CVS libtool.
1752 * commit: Update from CVS cvs-utils.
1754 2002-11-04 Akim Demaille <akim@epita.fr>
1756 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
1758 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
1760 2002-11-04 Akim Demaille <akim@epita.fr>
1762 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
1764 2002-11-04 Akim Demaille <akim@epita.fr>
1766 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
1767 used as `external', and Libtool 1.4.3.
1769 (LTLIBOBJS): Don't play with it.
1771 * Makefile.am (SUBDIRS): Remove intl.
1772 (ACLOCAL_AMFLAGS): Add -I config.
1773 (EXTRA_DIST): Add config/config.rpath.
1776 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
1778 2002-05-29 Gary V. Vaughan <gary@gnu.org>
1780 Preparations for refactoring syntax tables to allow reverse
1781 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
1782 speed of normal lookups in an array of unsigned short.
1784 * m4/input.c (single_quotes, single_comments, use_macro_escape):
1786 * m4/m4private.h (m4__single_quotes, m4__single_comments,
1787 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
1788 is for internal symbols which unavoidably pollute the global
1789 namespace, but are not published APIs.
1790 Adjusted all callers.
1791 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
1792 m4_set_comment, m4_set_syntax, set_syntax_internal,
1793 unset_syntax_attribute): Moved from this file...
1794 * m4/syntax.c: New. ...to this file.
1795 Also added an m4_syntax_exit stub for orthogonality.
1796 * src/main.c (main): Use it.
1797 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
1798 * m4/m4module.h: Reformatting. New prototypes.
1800 2002-05-29 Gary V. Vaughan <gary@gnu.org>
1802 * bootstrap (aclocal_apiversion): The aclocal apiversion is
1803 distinct from the automake release number (in that the apiversion
1804 apparently has no micro-version-component).
1805 (aclocal_apilibdir): Use it.
1807 2002-05-28 Gary V. Vaughan <gary@gnu.org>
1809 * m4/hash.c (m4_hash_resize): New function.
1810 * m4/hash.h: Add prototype.
1811 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
1812 benchmarking to find a good value for, say, autoconf. This is
1813 already a little quicker than before for me.
1815 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
1816 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
1818 * m4/hash.h: Adjust prototypes.
1820 2002-01-22 Akim Demaille <akim@epita.fr>
1822 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
1824 * tests/Makefile.am (package.m4): New.
1825 * tests/atlocal.in: Adjust to CVS Autotest.
1826 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
1827 * configure.ac: LIBOBJ is a forbidden string.
1828 Simplify AM_INIT_AUTOMAKE invocation.
1829 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
1832 2001-10-19 Akim Demaille <akim@epita.fr>
1834 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
1836 2001-10-19 Akim Demaille <akim@epita.fr>
1838 * m4/input.c (m4_next_token): Display where was opened what is
1841 2001-10-19 Akim Demaille <akim@epita.fr>
1843 * m4/macro.c (expand_argument): Display where was opened what is
1846 2001-10-18 Akim Demaille <akim@epita.fr>
1848 * m4/input.c, modules/m4.c: Formatting changes.
1850 2001-10-17 Gary V. Vaughan <gary@gnu.org>
1852 * bootstrap: s/configure.in/configure.ac/
1854 2001-10-16 Gary V. Vaughan <gary@gnu.org>
1856 * m4/symtab.c (m4_symbol_destroy): This function calls
1857 m4_symbol_popdef, which recycles a symbols memory when the last
1858 definition is popped. Since we were passing the address of the
1859 symbol name found in the symbol table, and it was being removed
1860 partway through m4_symbol_destroy() we were referencing freed
1861 memory for the balance of the function. Now we take a copy of the
1862 symbol name tring and use that as a key into the symbol
1863 table... that way if the original symbol name is freed, the copy
1866 2001-10-13 Akim Demaille <akim@epita.fr>
1868 * m4/ltdl.c: Update.
1870 2001-10-13 Akim Demaille <akim@epita.fr>
1872 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
1873 Don't gettextize internal error messages.
1875 2001-10-13 Akim Demaille <akim@epita.fr>
1877 * tests/macros.at (Arity and defn): New failing test.
1878 (Arity, defn, and freeze): New.
1880 Fix `Arity and defn'.
1882 * m4/input.c (m4_push_macro): Don't forget the arity.
1883 * modules/m4.c (defn): Likewise.
1885 2001-10-13 Akim Demaille <akim@epita.fr>
1887 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
1889 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
1890 (Propagation of traceon, Propagation of --trace): this new file.
1892 2001-10-13 Akim Demaille <akim@epita.fr>
1894 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
1895 interface instead of (name, argc...).
1896 Upon failure, specify which argument was guilty.
1899 2001-10-13 Akim Demaille <akim@epita.fr>
1901 * modules/evalparse.c: Save translators' time: don't translate
1902 internal error messages.
1903 (m4_evaluate): Simplify/normalize error messages.
1904 * doc/m4.texinfo (Eval): Adjust.
1906 2001-10-13 Akim Demaille <akim@epita.fr>
1908 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
1909 where no checking is needed.
1910 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
1911 interface instead of (name, argc...).
1913 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
1916 2001-10-13 Akim Demaille <akim@epita.fr>
1918 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
1919 exclude the builtin name from the count.
1920 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
1921 calling ifelse with a single argument is valid.
1922 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
1923 with 1 and 2 args, mostly to strengthen the test suite.
1925 2001-10-13 Akim Demaille <akim@epita.fr>
1927 * m4/output.c (m4_make_diversion, m4_insert_file)
1928 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
1930 2001-10-12 Gary V. Vaughan <gary@gnu.org>
1932 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
1933 since we call these things builtins in the rest of the code!
1935 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
1937 2001-10-12 Gary V. Vaughan <gary@gnu.org>
1939 Rather than forcing each builtin definition to manage its own
1940 argument range checking, tabulate the maxima and minima for all
1941 builtins in each module. This forces us to consider what the
1942 valid ranges for each builtin should be, and moves the checking
1943 code out of each builtin implementation and into the builtin
1944 caller infrastructure.
1946 * m4/m4module.h (struct m4_builtin): Add argument minima and
1948 * m4/m4private.h (struct m4_token): Reflect them here too.
1949 * m4/input.c (struct input_block): ...and here.
1950 (m4_token_copy): New function for token copying.
1951 (init_macro_token): Copy them from a token to the input stack.
1952 (m4_next_token): Don't forget to initialise them for text
1954 * m4/macro.c (expand_argument): Use m4_token_copy, and also
1955 check argument counts before calling the builtin handler.
1956 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
1957 (m4_symbol_macro): Likewise.
1958 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
1959 parameters. Updated all callers.
1960 (m4_builtin_define): Ditto.
1961 (m4_macro_pushdef, m4_macro_define): Ditto.
1962 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
1963 * modules/evalparse.c: Declare argument counts for defined
1964 builtins and remove explicit calls to m4_bad_argc().
1965 * modules/gnu.c: Ditto.
1966 * modules/load.c: Ditto.
1967 * modules/m4.c: Ditto.
1968 * modules/modtest.c: Ditto.
1969 * modules/mpeval.c: Ditto.
1970 * modules/perl.c: Ditto.
1971 * modules/shadow.c: Ditto.
1972 * modules/stdlib.c: Ditto.
1973 * modules/time.c: Ditto.
1976 2001-10-10 Gary V. Vaughan <gary@gnu.org>
1978 The trace semantics now attach the trace bit to a symbol name.
1979 For as long as a traceon(`foo') is active, calls to foo will be
1980 traced regardless of intervening undefines or module unloads.
1981 Fixed the flag propogation issues differently to the fixes
1982 reverted with the last attempt at nailing down trace:
1984 * m4/m4private.h: This file is not visible outside of the m4
1985 source tree, so I removed all the `M4_' and `m4_' prefixes to save
1986 on typing. Updated all clients.
1987 (m4_token): New typedef contains the fields that need to be passed
1988 around with the low level tokeniser.
1989 (m4_token_data): Removed.
1990 (m4_symbol): Now contains the traced flag again.
1991 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
1992 the trace bit set. This change is contained entirely within this
1993 module and doesn't leak out into the callers. Updated all
1995 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
1996 new fields in m4_token. Updated all clients.
1997 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
1998 that `groks_macro_args' and `blind_if_no_args' flags are retained
1999 when defn() results are passed around in m4 code. Updated all
2001 (m4_builtin_define): Ditto.
2002 (m4_macro_pushdef, m4_macro_define): Ditto.
2003 * m4/input.c (struct input_block): Add a flags field to facilitate
2005 (m4_push_macro): ...use it.
2006 (init_macro_token): Retrieve it.
2007 (m4_next_token): Initialise it.
2008 * m4/macro.c (expand_argument): Copy it.
2009 * m4/m4module.h: Adjust.
2010 * tests/builtins.at: Adjust the expected output of the trace
2011 tests to reflect the change in semantics.
2012 * tests/modules.at (modules: trace): Check that unloading a
2013 module which supplies a traced symbol definition doesn't lose te
2016 2001-10-07 Gary V. Vaughan <gary@gnu.org>
2018 * modules/gnu.c (m4_macro_table): Display the timetamp when
2019 expanding __m4_version__.
2021 * configure.ac (--with-modules): Forgot a comma in the
2022 AC_HELP_STRING parameter list.
2024 2001-10-05 Gary V. Vaughan <gary@gnu.org>
2026 * bootstrap: Remove aclocal.m4t when it is no longer required.
2028 2001-10-05 Akim Demaille <akim@epita.fr>
2030 * tests/Makefile.am: Adjust for gnuprog2.
2031 * tests/m4.in: There can be a leading path.
2032 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
2033 * tests/testsuite.at: Adjust to the most recent Autotest.
2034 (AT_CHECK_M4_FILTER): Fix and rename as...
2036 * tests/others.at: Use it.
2038 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
2039 variable in shell scripts, one uses `$'...
2041 2001-10-04 Gary V. Vaughan <gary@gnu.org>
2043 * configure.ac: `rm -f $m4_getopt_h' was lost.
2045 2001-10-04 Gary V. Vaughan <gary@gnu.org>
2047 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
2048 time. Define it for config.h in order to...
2049 * src/main.c (main): ...display the timestamp for --version.
2051 2001-10-04 Akim Demaille <akim@epita.fr>
2053 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
2054 previous builtins `regexp' and `patsubst'.
2055 (regexp, patsubst): Use them.
2056 (eregexp, epatsubst): New builtins.
2057 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
2058 (Epatsubst and Patsubst, Eregexp and Regexp): these.
2059 (Extensions): More info on REs.
2061 2001-10-04 Akim Demaille <akim@epita.fr>
2063 * modules/modtest.c (init_handler): Consistently output to stderr.
2064 (finish_handler): New.
2065 (test): The `if' is an `assert'.
2066 * tests/modules.at: Adjust.
2068 2001-10-04 Akim Demaille <akim@epita.fr>
2070 * m4/utility.c (m4_bad_argc): Detail the mismatches.
2072 2001-10-01 Akim Demaille <akim@epita.fr>
2074 * tests/generate.awk: Tag the tests with `documentation'.
2075 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
2076 Use the make the existing modtest tests more uniform, and complete
2077 the set of possibilities.
2079 2001-10-01 Akim Demaille <akim@epita.fr>
2081 * config/gmp.m4: Consult the user before using GMP: use
2083 * configure.ac: Adjust.
2084 * modules/gmp.c: No protection needed as the module is not built
2087 2001-10-01 Akim Demaille <akim@epita.fr>
2089 * tests/generate.awk: Remove debugging code.
2090 (fatal): Specify the current location.
2092 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
2093 * modules/gnu.c, modules/m4.c: Use M4ARG.
2095 2001-10-01 Akim Demaille <akim@epita.fr>
2097 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
2098 (m4_regexp_compile): New.
2099 (regexp, patsubst): Use it.
2101 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2103 Reinstate the memory handling improvements from the patch I just
2104 reverted. Relevant ChangeLog entries repeated here:
2106 * m4/module.c (m4_module_remove): New function that holds the core
2107 of the old m4_module_unload.
2108 (m4_module_unload): Use it.
2109 (m4_module_unload_all): When we know the modules will never be
2110 used again (i.e. on exit), free up as much module memory as
2111 possible. There are still some artifacts from resident modules
2112 living inside ltdl.c, but everything else is freed.
2113 * m4/debug.c (m4_debug_exit): Free memory allocated in
2115 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
2116 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
2117 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
2118 * m4/m4module.h: Updated prototypes.
2119 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
2120 * m4/hash.h: Updated prototypes.
2121 * src/main.c (main): Use all these new functions to clean up as
2122 much memory as possible before exit.
2124 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2126 Reverted my large patch for removing the old m4_symbol
2127 structure on 2001-09-20. We are still not happy about the way
2128 trace works in conjunction with defn and undefine, and leaving
2129 the reverted patch active prevents us from moving the traced
2130 bit from the definition back to the symbol.
2132 2001-09-30 Gary V. Vaughan <gary@gnu.org>
2134 * configure.in: Moved to...
2135 * configure.ac: ...here. Added a libtool like timestamped
2136 banner, and tidied up the libltdl cruft.
2137 * config/mkstamp: Script to extract a timestamp from ChangeLog.
2138 * modules/Makefile.am (INCLTDL): Removed. This is required
2139 only when libltdl is configured in a subdirectory.
2140 * src/Makefile.am: Ditto.
2141 (LIBADD_DL): No need to add this again, libtool already knows
2142 that libm4.la depends on it.
2143 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
2146 * TODO: stackovf.c is basically broken.
2147 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
2149 2001-09-28 Akim Demaille <akim@epita.fr>
2151 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
2153 2001-09-27 Akim Demaille <akim@epita.fr>
2155 * tests/m4.in: Don't use short options.
2156 Simplify the stderr signature normalization.
2158 2001-09-27 Akim Demaille <akim@epita.fr>
2160 tests/m4 shall be position independent.
2164 * tests/testsuite.at: No args to AT_INIT.
2165 * configure.in, tests/Makefile.am: Adjust.
2167 2001-09-22 Akim Demaille <akim@epita.fr>
2169 Autotest has changed again.
2171 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
2172 (package.m4): Remove.
2173 * configure.in: Adjust to LIBADD_GMP.
2175 2001-09-21 Gary V. Vaughan <gary@gnu.org>
2177 * config/gmp.m4 (AC_ARG_WITH): Removed.
2178 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
2179 (AC_LIB_GMP): When performing a test compile against libgmp,
2180 include the header gmp.h if possible, and link against -lgmp. If
2181 they both work define USE_GMP.
2182 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
2183 (mpeval_LTX_init_func): Complain on load that there was no libgmp
2186 2001-09-20 Gary V. Vaughan <gary@gnu.org>
2188 * m4/evalparse.c: Moved to...
2189 * modules/evalparse.c: ...here. This code is shared between
2190 modules/mpeval.c and modules/m4.c, so there is no need to pollute
2191 the libm4 API with its details. Moderately rewritten to interface
2192 into its clients more simply.
2193 * m4/eval.c: Deleted. Migrated functionality to...
2194 * modules/m4.c: ...here.
2195 (builtin_eval): Implemented in terms of the new interface style.
2196 * modules/mpeval.c (builtin_mpeval): Ditto.
2197 * m4/m4module.h: Removed references to the former m4/eval.c.
2198 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
2199 (EXTRA_libm4_la_SOURCES): Deleted.
2200 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
2201 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
2203 2001-09-20 Akim Demaille <akim@epita.fr>
2205 * config/gmp.m4 (AM_WITH_GMP): Rename as...
2207 By default, use gmp.
2209 * configure.in: Adjust.
2210 Use Automake conditionals for USE_GMP.
2211 Always compute sizeof (long long int).
2212 This was a bug BTW, as `eval' (not `mpeval') depends on it:
2213 before, it was used _only_ if mpeval was not activated.
2214 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
2215 (mpeval_la_LIBADD): New macros.
2216 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
2218 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
2219 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
2222 2001-09-20 Akim Demaille <akim@epita.fr>
2224 * tests/Makefile.am (package.m4): New.
2225 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
2227 2001-09-20 Gary V. Vaughan <gary@gnu.org>
2229 More cleanup. After the last patch, m4_symbol holds nothing but
2230 the head of a chain of m4_token_data. So I have removed the old
2231 m4_symbol, so that m4_token_data chains are stored directly in the
2232 value cell of a hash table node. But there's more... m4_symbol
2233 was a more natural name for the symbol value cell, and now that it
2234 is gone I have renamed the former m4_token_data structure to
2235 m4_symbol. This change turned out to be a pig to get right, since
2236 the original code didn't need to modify the value cell itself,
2237 since changing the chain happened inside the m4_symbol that used
2238 to be returned -- I had to pass the address of the value cell
2239 across various function calls, incase the head value changed. I
2240 also tightened up the memory management to help me find a nasty
2241 memory corruption bug that took me all night to track down...
2243 * m4/m4private.h (struct m4_symbol): Removed.
2244 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
2246 * m4/hash.c (m4_hash_iterator_value): Return the address of the
2247 value cell. Updated all callers.
2248 * m4/symtab.c: Took advantage of the simplification in the data
2249 structures to rewrite a lot of this file more simply. There is
2250 still some room for optimisation here, but we should tackle that
2251 systematically closer to the release.
2253 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
2254 revealed. This version is ahead of CVS libtool until I get chance
2255 to flush my changes.
2256 * m4/module.c (m4_module_remove): New function that holds the core
2257 of the old m4_module_unload.
2258 (m4_module_unload): Use it.
2259 (m4_module_unload_all): When we know the modules will never be
2260 used again (i.e. on exit), free up as much module memory as
2261 possible. There are still some artifacts from resident modules
2262 living inside ltdl.c, but everything else is freed.
2263 * m4/debug.c (m4_debug_exit): Free memory allocated in
2265 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
2266 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
2267 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
2268 * m4/m4module.h: Updated prototypes.
2269 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
2270 * m4/hash.h: Updated prototypes.
2271 * src/main.c (main): Use all these new functions to clean up as
2272 much memory as possible before exit.
2274 2001-09-18 Gary V. Vaughan <gary@gnu.org>
2276 The `traced' flag needs to be attached to the definition of a
2277 symbol rather than the current symbol containing the definition.
2278 Implementing this showed up some long standing post 1.4 bugs in
2279 flag propogation which I also fixed.
2281 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
2282 (struct m4_token_data): And add it back in here.
2283 * m4/input.c (init_macro_token): Propogate the traced flag
2285 * m4/macro.c (expand_argument): Ditto.
2286 * tests/builtins.at (trace2, trace3): New tests based on Akim's
2289 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2291 * m4/m4private.h (struct m4_token_data): Simplified by removing
2292 the redundant `traced' flag, and one level of structure nesting.
2293 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
2294 * m4/input.c (init_macro_token): No need to initialise removed
2296 * m4/macro.c (expand_argument): No need to copy it either.
2297 * m4/utility.c (m4_token_data_func_traced): Or provide an access
2300 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
2301 dependant on multiple symbols with the same key, so preserving
2302 relative symbol order in each bucket during resizing is no longer
2303 required. The resize function is considerably faster as a result.
2305 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
2306 s/m4_symbol_insert/m4_symbol_define/g;
2307 s/m4_builtin_insert/m4_builtin_define/g;
2308 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
2310 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2312 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
2313 commits, the m4_lookup_symbol dispatch function is split into
2314 specialised functions that must be called directly.
2316 * m4/m4module.h (m4_symbol_lookup_t): Removed.
2317 * m4/symtab.c (m4_lookup_symbol): Removed.
2318 (m4_symbol_builtin, m4_symbol_macro): New functions.
2319 * m4/builtin.c (m4_builtin_define): Split into...
2320 (m4_builtin_pushdef, m4_builtin_insert): ...these.
2321 (m4_macro_define): Split into...
2322 (m4_macro_pushdef, m4_macro_insert): ...these.
2323 * src/main.c (main): Set command line macros from `-D' parameters
2324 using `m4_macro_define'.
2326 2001-09-08 Gary V. Vaughan <gary@gnu.org>
2328 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
2329 this from m4_remove_table_reference_symbols().
2330 * m4/m4module.h, m4/module.c: Updated all references.
2332 2001-09-07 Akim Demaille <akim@epita.fr>
2334 * modules/stdlib.c, modules/times.c: Misc cleanups.
2336 2001-09-07 Akim Demaille <akim@epita.fr>
2338 * configure.in: We now need Autoconf 2.52e.
2339 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
2340 and `M4_SYMBOL_DELETE'.
2341 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
2342 * src/main.c (main): Adjust.
2344 2001-09-06 Gary V. Vaughan <gary@gnu.org>
2346 Fix the obstack.h problem once and for all! At configure time we
2347 can test for a system supplied obstack.h: depending on the
2348 result, we now generate system.h with an #include of the correct
2349 header. As a bonus, I've also added a --with-included-obstack,
2350 incase the user doesn't like the system obstack for some
2351 reason... and also we can test the shipped obstack on a system
2352 that has oe of its own. We also now need to be careful to add
2353 build directories to the include search path, since the generated
2354 system.h will be in the build tree.
2356 * configure.in (AC_CONFIG_FILES): Generate system.h from
2358 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
2359 include the system obstack header or the copy shipped with M4.
2360 Allow the user to override configure and force the build to use
2361 the shipped version.
2362 * m4/system-h.in: New file, template for...
2363 * m4/system.h: ...this. Now deleted.
2364 * m4/m4module.h: Include system.h before everything else.
2365 * src/freeze.c: Ditto.
2366 * m4/Makefile.am (dist-hook): Remove generated system.h.
2367 (INCLUDES): Check builddir for generated headers before checking
2369 * modules/Makefile.am (INCLUDES): Ditto.
2370 * src/Makefile.am (INCLUDES): Ditto.
2372 2001-09-05 Gary V. Vaughan <gary@gnu.org>
2374 * TODO: Remove the items that have been addressed already.
2376 2001-09-05 Akim Demaille <akim@epita.fr>
2378 * src/main.c (main): Standardize --version.
2380 2001-09-05 Akim Demaille <akim@epita.fr>
2382 * modules/format.c (format): Have a bigger `str'.
2384 2001-09-05 Akim Demaille <akim@epita.fr>
2386 Rationalize warnings, reporting the macro name as if it were a
2387 program name, and assertions.
2389 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
2391 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
2393 Use assert for internal errors.
2394 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
2396 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
2398 * tests/builtins.at (pushpop): Adjust.
2400 2001-09-05 Akim Demaille <akim@epita.fr>
2402 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
2405 2001-09-05 Akim Demaille <akim@epita.fr>
2407 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
2408 * m4/macro.c, m4/symtab.c: Adjust.
2410 2001-09-05 Akim Demaille <akim@epita.fr>
2412 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
2413 (m4_symbol_pop, m4_symbol_del): this.
2414 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
2415 (m4_symbol_popdef, m4_symbol_delete): New.
2416 (m4_lookup_symbol): Adjust.
2417 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
2419 2001-09-05 Akim Demaille <akim@epita.fr>
2421 * m4/m4module.h (m4_symbol_lookup): Rename as...
2422 (m4_symbol_lookup_t): this.
2424 2001-09-05 Akim Demaille <akim@epita.fr>
2426 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
2428 * m4/symtab.c (m4_lookup_symbol): Adjust.
2430 2001-09-03 Gary V. Vaughan <gary@gnu.org>
2432 Bootstrap will now work with Libtool 1.4.1 or higher:
2433 * bootstrap: Remove stale autom4te.cache files when
2435 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
2437 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
2438 libtool.m4 directly.
2439 Run libtoolize to refresh ltmain.sh.
2440 * config/ltmain.sh: Deleted.
2441 * acinclude.m4: Deleted.
2442 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
2444 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
2445 implementation for the cvs impaired libtool user.
2447 2001-09-03 Akim Demaille <akim@epita.fr>
2449 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
2451 Avoid using `default' in switch, as it hides useful compiler
2452 warnings when a case is forgotten.
2454 2001-09-03 Akim Demaille <akim@epita.fr>
2456 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
2457 is no such thing as `WITH_MODULES'.
2459 2001-09-03 Akim Demaille <akim@epita.fr>
2461 Improve the test suite's selfcontainedness.
2463 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
2464 (Include, Undivert): Tag the other input files.
2465 * tests/generate.awk: Catch `@comment file:'.
2466 `-I $src' is no longer needed.
2467 `next' is really like `return': the rest is skipped.
2468 Adjust to `input.m4'.
2469 (fatal): New function.
2470 * tests/foo, tests/incl.m4: Remove.
2472 2001-09-01 Gary V. Vaughan <gary@gnu.org>
2474 The shadowing mechanism and, infact, the whole symbol table
2475 implementation was creaking under the weight of the features piled
2476 on top of it. We now have a separate hash table module which will
2477 dynamically resize to keep symbol density withing good performace
2478 limits, and a new symtab module layered above it. Symbol lookups
2479 are now marginally more efficient (since the shadowed flag is no
2480 longer required) and symbol removal, such as on module unload, is
2481 considerably faster due to a reorganisation of the data structures
2484 * src/main.c (main): Don't mention `-H'.
2485 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
2488 * m4/hash.c: New generalised dynamic hash table data structure
2490 * m4/hash.h: Public interface.
2491 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
2492 (libm4_la_SOURCES): Add hash.c.
2493 * m4/symtab.c: More or less rewritten from scratch, within the
2494 bounds of the previous API.
2495 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
2496 call. Updated all callers.
2497 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
2498 declarations to reflect API changes.
2499 (M4INIT): Generate a declaration too, to avoid the warning with
2500 --enable-debug builds.
2503 * m4/utility.c (hash_table_size): Removed.
2504 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
2505 names, which are then looked up by builtin_dumpdef() as necessary.
2506 This implies a small speedup in builtin_symbols(), which discarded
2507 all of the symbol info under the old call.
2508 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
2509 shadowing is implicit in respect to the new data structures.
2510 symbol names are no longer duplicated here, they are stored in the
2511 key field of the hash table.
2512 Moved macro_args and blind_no_args...
2513 (m4_token_data): ...to here.
2514 m4/macro.c (expand_macro): Added a name argument since the symbol
2515 name is no longer copied into each struct m4_symbol. Modified all
2517 (collect_arguments): Ditto.
2518 * modules/m4.c (set_trace): Ditto.
2519 * modules/gnu.c (builtin_symbols): Updated.
2520 * src/freeze.c (produce_symbol_dump): Much improved in light of
2521 the improved symbol table layout.
2523 2001-09-01 Gary V. Vaughan <gary@gnu.org>
2525 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
2527 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
2528 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
2529 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
2530 SYMBOL_HANDLE): Ditto.
2531 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
2532 modules/gnu.c, modules/m4.c, src/freeze.c,
2533 src/main.c: Updated all references.
2535 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
2536 Automake 1.5 chokes on dynamic source file lists, Besides, it is
2537 already listed in m4_LDADD... how did that ever used to work?
2538 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
2540 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
2541 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
2543 * tests/m4: Don't call the m4 wrapper script with libtool, it
2544 works fine all by itself.
2546 2001-08-30 Gary V. Vaughan <gary@gnu.org>
2548 The experimental `changeword' feature never took off, and has
2549 no obvious advantages over `changesyntax' to compensate the
2550 enormous speed penalty it carries:
2551 * configure.in (ENABLE_CHANGEWORD): Removed.
2552 * m4/m4module.h (m4_set_word_regexp): Removed.
2553 * m4/m4private.h (m4_token_data): Removed original_text field.
2554 * m4/utility.c (m4_token_data_orig_text): Removed.
2555 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
2556 * m4/macro.c: Ditto.
2557 * src/main.c: Ditto.
2558 * modules/Makefile.am (changeword.la): Removed.
2559 * modules/changeword.c: File removed.
2560 * doc/m4.texinfo: References to changeword and --word-regexp
2562 * po/POTFILES.in: modules/changeword.c removed.
2563 * tests/atlocal.in (ENABLE_CHANGEWORD): Removed.
2564 * tests/builtins.at (changeword): Test removed.
2566 2001-08-30 Akim Demaille <akim@epita.fr>
2568 * bootstrap.sh: Create aclocal.m4 instead of modifying it.
2569 This also help having a single list of m4 files: in
2571 * config/Makefile.am (STANDARD_MACROS): Rename as...
2572 (ACLOCAL_MACROS): this.
2573 (list-standard-macros): Remove.
2576 2001-08-29 Gary V. Vaughan <gary@gnu.org>
2578 In an attempt to moderate my egomania...
2579 * tests/modules.at: Remove attributions.
2581 * tests/generate.awk: When making substitutions to "@&t@", either
2582 "&" or "\&" in the substitution string argument to gsub refer back
2583 to the matched text. "@\\&t@" seems to work though, Tests 43 and
2586 2001-08-29 Akim Demaille <akim@epita.fr>
2588 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)
2589 (include, indir, multiquotes, patsubst, pushdef/popdef, regexp)
2590 (sync-lines, trace, translit, undivert, wrap): Move to...
2591 * tests/builtins.at: this new file.
2592 * tests/others.at (Discard comments, import-environment): Move to...
2593 * tests/options.at: this new file.
2595 2001-08-29 Akim Demaille <akim@epita.fr>
2597 * tests/others.at (Freezing modules)
2598 (--module-directory: absolute path, modpath2, modpath3)
2599 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
2600 * tests/modules.at: here, new file.
2601 * tests/others.at, tests/generate.awk: Add a banner.
2602 * tests/testsuite.at: Adjust.
2603 (AT_CHECK_M4_FILTER): New, but unused.
2605 2001-08-29 Akim Demaille <akim@epita.fr>
2607 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
2609 * tests/others.at (wrap): Inline wrap.m4.
2610 (shadow): Inline shadow.m4.
2611 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
2612 * tests/m4: Simplify.
2614 2001-08-29 Akim Demaille <akim@epita.fr>
2616 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
2619 2001-08-29 Akim Demaille <akim@epita.fr>
2621 * tests/generate.awk (normalize): s/@__@/@&t@/.
2623 2001-08-28 Akim Demaille <akim@epita.fr>
2625 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.
2627 2001-08-28 Gary V. Vaughan <gary@gnu.org>
2629 * bootstrap (generate.awk): Generate test cases with new script.
2631 2001-08-27 Akim Demaille <akim@epita.fr>
2633 * tests/Makefile.am (installcheck-local): Don't use
2634 `dc_install_base' which is not visible here, but `exec_prefix'
2635 which is clearly the RT anyway.
2636 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
2637 related to testing a now installed m4.
2638 * tests/m4: Do it here.
2640 2001-08-27 Akim Demaille <akim@epita.fr>
2642 * tests/others.at (indir): Formatting change.
2644 2001-08-27 Akim Demaille <akim@epita.fr>
2646 * tests/Makefile.am (installcheck-local): New.
2647 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
2649 Prefer options over envvars.
2650 * src/main.c (main): First bug caught by the test suite (yeah!):
2651 --batch lacked a `break' which resulted in an accidental
2652 invocation of --discard-comments.
2654 2001-08-27 Akim Demaille <akim@epita.fr>
2656 * tests/others.at (capitalize, changeword, comments, ddivert)
2657 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
2658 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
2659 (sysv-args, trace, translit, undivert): Don't rely on files in
2660 examples/: AT_DATA them.
2662 2001-08-27 Akim Demaille <akim@epita.fr>
2664 Let the test suite use a wrapper around the not installed m4 to
2665 pretend it is (installed).
2667 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
2668 such a way that m4 does not process them.
2669 * configure.in: The package name seems to be `m4', not `M4'.
2671 * tests/atlocal.in (at_package, M4): Remove.
2672 * tests/testsuite.at, tests/others.at: Use m4, not $M4.
2674 2001-08-27 Akim Demaille <akim@epita.fr>
2676 * tests/Makefile.am (CLEANFILES): Remove.
2677 (DISTCLEANFILES, clean-local): New.
2678 * examples/mktests.sh: Remove.
2680 2001-08-27 Akim Demaille <akim@epita.fr>
2682 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
2683 Don't use aclocal: it's written by hand.
2684 * aclocal.m4: m4_include all the files instead of being built by
2686 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
2687 until it reads the traces by itself.
2688 * configure.in: Require Autoconf 2.42c as we are now using
2689 AC_CONFIG_TESTDIR instead of AT_CONFIG.

2706 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
2707 Robert Collins, building on Cygwin no longer requires Windows
2708 import and export symbol decorations.
2709 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.

2723 2001-08-20 Gary V. Vaughan <gary@gnu.org>
2725 Ansify the source. Previously we had a mix, where my code was
2726 in a K&R compatible style, and the preexisting code was in ANSI
2727 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
2728 and now the code base is much cleaner.

2731 VOID macro and all users.

2771 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
2772 * modules/m4.c (undivert): Disable the possibility of undiverting
2773 several files at once: it is not documented, it is inconsistent
2774 with the other macros, it can be straightforwardly mocked by
2775 several invocations, and most importantly, it prevents the
2776 possibility of other kinds of extension.
2777 Use `m4_numeric_arg'.
2779 2001-08-20 Akim Demaille <akim@epita.fr>
2781 * examples/include.m4: Typo.
2782 * tests/generate.awk: Really add it.
2783 * tests/Makefile.am: Adjust.
2784 * tests/others.at (Discard comments): It sure fails without `-c'.
2785 (include, undivert): Add -I examples/.
2787 2001-08-20 Akim Demaille <akim@epita.fr>
2789 Use sprintf, not ecft and friends since it is standard, portable,
2790 simplifies the code, and since the latter is even deprecated
2791 according to the GNU libc documentation.
2793 * modules/format.c: Drop evct support.
2795 2001-08-19 Gary V. Vaughan <gary@gnu.org>

2939 Drop Autoconf 2.13 compatibility.
2941 * configure.in (changeword): No need to undefine it, as anyway if
2942 it's defined, M4sugar moved it as m4_changeword.

3000 (M4FINISH_HANDLER): And similarly for finish functions.

3002 -- Add indirection to the CONC macro so that arguments are
3004 * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
3005 * modules/shadow.c (m4_init_module): Ditto.

3017 instead of the old module argument.
3018 (m4_builtin_table_install): Ditto.

3040 module association does not belong with the symbol...
3041 * m4/input.c (struct m4_builtin): ...it belongs with the builtin

3061 * tests/gethem: Use them.
3063 2001-08-14 Gary V. Vaughan <gary@gnu.org>

3080 shell variable m4_cv_func_obstack_h.
3081 * tests/defs (M4): Be more careful about relative path to libtool
3082 script and m4 binary by using $srcdir.
3084 * src/main.c (main): Use lt_dlinsertsearchdir to prepend -M
3085 optargs to the existing libltdl search path.
3086 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.
3087 * m4/ltdl.c: Updated.

3093 * src/main.c (main): Add `-b' (for `batch') mode switch to force
3094 interactive mode off.

3160 with symbol insertion and deletion with resident modules.
3161 * m4/ltdl.c, m4/ltdl.h: Update to latest unreleased versions to
3162 use resident modules feature.
3164 2000-11-30 Gary V. Vaughan <gary@gnu.org>
3166 * TODO: Updated. Removed some cruft that has since been fixed
3167 or implemented. Added some more entries.
3170 * modules/README: Updated.
3171 * doc/m4.texinfo: Updated.
3173 * modules/gnu.c (builtin_functions): Make indir orthogonal to
3174 builtin, in that each is recognised as a macro only with parameters
3175 (builtin_indir): Passing 0 arguments is now an error, as with
3178 * src/main.c (usage): Added missing description of `-c' option.
3180 2000-11-29 Gary V. Vaughan <gary@gnu.org>
3182 Consolidate the myriad of dispersed test scripts into the
3183 tests subdirectory. I think I now have all the file where I
3184 want them, so there shouldn't be anymore upheaval =)O|

3223 modules/unfrozen.m4, modules/unload.test: Removed.
3225 Move the implementation of GMP support for the mpeval() builtin
3226 into a loadable module that depends on libgmp. mpeval() and
3227 eval() share a common parser, now in m4/evalparser.c; the code
3228 in m4/numb.c and m4/numb.h is now physically split between
3229 m4/eval.c (the eval() backend) and modules/mpeval.c (the
3230 mpeval() backend), rather than being differentiated by cpp
3231 macros and multiple inclusion. The mpeval module is always
3232 built but will generate an diagnostic if it is used from an
3233 installation that didn't link in the gmp library.
3234 * modules/Makefile.am: build and install the new mpeval module.
3235 * modules/mpeval.c: Now contains the former parts of m4/numb.c
3236 and m4/numb.h that are required for gmp support in mpeval().
3237 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
3238 * m4/evalmp.c: Removed.
3239 * m4/m4module.h: Removed conditional prototype for
3241 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
3242 and m4/numb.h that do not rely on gmp.
3243 * m4/evalparse.c: New file, contains the shared parts of the
3244 eval() and evalmp() parser implementations, and is no longer
3245 unencumbered by cpp magic to uncover the right parts.
3246 * m4/numb.h: Removed. It's former contents are split between
3247 m4/eval.c and modules/mpeval.c.
3250 * tests/other-tests/changeword.test: New test. Rudimentary
3251 testing of changeword builtin runs only if --wnable-changeword
3252 was used at configure time.
3253 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
3254 alternation correctly. Split into two expressions to compensate.
3255 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
3256 * modules/Makefile.am: Build changeword module.
3257 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
3258 only when --enable-changeword was passed to configure.
3259 (builtin_changeword): If --enable-changeword was not used, then
3260 report that changeword() builtin has no support in m4 binary.
3262 2000-11-28 Gary V. Vaughan <gary@gnu.org>
3264 * src/main.c (main): Fixed a particularly nasty bug is
3265 user_search_path setting -- the -M flag processing must be
3266 extremely careful with search path ordering, or else the default
3267 installed module directory (possibly containing modules from a
3268 previous release) is placed earlier in the search path than any -M
3269 arguments (which are relied upon to load uninstalled modules with
3270 most of the tests in the regresion suite).
3272 * modules/load.c (builtin_load): Nasty hack to prevent adding
3273 symbols to symtab again if a module is loaded more than once.
3274 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
3276 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
3277 possible NULL pointer dereference.
3279 * m4/module.c (m4_module_find_by_modname): Renamed from
3280 m4_module_modname_find. Fixed all references.
3281 (m4_module_find_by_builtin): New function.
3283 * modules/modfreeze.test: load the `load' module with each
3285 * src/freeze.c (produce_frozen_state): Simplified in light of
3286 module field in m4_symbol. Allow a third argument for text macros
3287 to name the originating module.
3288 (reload_frozen_state): ditto.
3289 * m4/m4module.h: Fixup prototypes.
3290 * m4/builtin.h (m4_builtin_define): Add a module argument so
3291 that symbols can be registered against the defining module.
3292 (m4_macro_define): ditto.
3293 * m4/m4private.h (m4_symbol): Make the module field const to save
3294 on casting in the rest of the code.
3295 (SYMBOL_MODULE): New macro.
3297 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
3298 symbol reference maintenance bugs when removing a symbol from the
3301 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
3303 2000-11-27 Gary V. Vaughan <gary@gnu.org>
3305 * configure.in (m4_cv_func_obstack): A better check for whether
3306 libc has an obstack implementation.
3307 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
3309 * configure.in (--with-modules): Changed semantics. This
3310 option is now used to list modules to be preopened.
3311 * src/m4.h: #include "ltdl.h" unconditionally.
3312 * src/main.c: Removed all dependencies on WITH_MODULES.
3313 * src/freeze.c: ditto.
3314 * modules/Makefile.am: ditto.
3315 * m4/m4.c (builtin_m4exit): ditto.
3316 * modules/modpath1.test: ditto.
3317 * modules/modpath2.test: ditto.
3318 * modules/modpath3.test: ditto.
3319 * modules/modpath4.test: ditto.
3320 * modules/modtest.test: ditto.
3321 * modules/shadow.test: ditto.
3322 * modules/unload.test: ditto.
3324 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
3325 comes up on demand in LTLIBOBJS now.
3326 * configure.in (getopt_long): Creating and relying on a link for
3327 getopt.h on hosts with no getopt_long() of thier own works
3328 correctly now. This is necessary so that callers of getopt_long()
3329 can simply `#include <getopt.h>': the naive way of doing this
3330 would end up using our own getopt.h and the installed
3331 getopt_long(), which is asking for trouble!
3332 (obstack_init): A similar argument applies to obstack.h and
3335 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
3336 On Solaris-2.5 (at least) the native dlopen implementation
3337 gets confused about m4.o when looking for module "m4". This
3338 version always looks for .la an .$lib_ext suffixed names first
3339 to work around the problem. Sigh.
3341 * po/POTFILES.in: Take account of these file movements.
3342 * src/Makefile.am (m4_SOURCES): removed eval.c.
3343 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
3344 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
3345 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
3346 * modules/m4.c (builtin_eval): Use m4_evaluate().
3347 * m4/eval.c: Moved here from src/eval.c to facilitate
3348 implementation of eval() builtin as part of the `m4' loadable
3350 (m4_evaluate): renamed from evaluate for namespace cleanliness.
3351 * m4/numb.c: Moved here from src/numb.c, since it is #included
3352 into eval.c at compile time.
3353 * m4/m4module.h (m4_evaluate): Added prototype.
3354 * src/m4.h (evaluate): Removed prototype.
3356 2000-11-25 Gary V. Vaughan <gary@gnu.org>
3358 * modules/perl.c (builtin_perleval): Use PL_na for
3359 compatibility with perl-5.6.
3361 * src/main.c (main): It is now safe to
3362 ``m4_module_install("m4")'', without tripping over the m4
3364 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
3365 versions having fixed the insidious module search order bug.
3367 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
3368 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
3370 * configure.in: Figure out whether to use the installed
3371 getopt.h or the supplied one.
3372 * src/Makefile.am: ditto.
3374 * po/POTFILES.in: List files in their new positions.
3376 * config/ltmain.sh: This needs to be checked in to match the
3377 libtool macros copied to acinclude.m4 (until a released
3378 libtool copes with m4's needs).
3379 * bootstrap: Run gettextize.
3381 2000-11-24 Gary V. Vaughan <gary@gnu.org>
3383 * AUTHORS: Added my details.
3386 * bootstrap: temporary update until released libtool catches up.
3388 * All files: Use new GNU GPL copyright blurb with current contact
3391 * configure.in (LTLIBOBJS): Use canonical code for calculation of

3422 * modules/gnu.c: New file implementing a new loadable module wuth
3423 definitions for all the gnu extension builtins.
3424 * modules/format.c: Moved here from src/format.c. Now included
3427 * src/main.c (main): Load the traditional module if m4 was
3428 started in `no_gnu_extensions' mode.
3429 * modules/traditional.c: New file implementing the ``unix'' macro,
3430 required when m4 is executed in traditional mode, as a loadable
3433 * src/main.c: Renamed from m4.c to avoid confusion with
3435 (main): Always load the m4 module.
3436 * modules/m4.c: New file implementing a new loadable module with
3437 definitions for all m4 builtins that are not gnu extensions.

3445 renaming all exported symbols to use the prefix ``m4_''.
3446 * m4/builtin.c: ditto.

3448 * m4/symtab.c: ditto.
3449 * m4/debug.c: ditto.
3450 * m4/input.c: ditto.
3451 * m4/output.c: ditto.
3453 * m4/ltdl.h, m4/ltdl.c: ditto.
3454 * m4/utility.c: Odd functions moved here from files in the src
3455 directory to facilitate builtin migration.
3457 2000-08-12 Gary V. Vaughan <gary@gnu.org>
3459 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
3460 error message, to make translators' jobs a little easier.
3461 (builtin_builtin): ditto.
3462 (builtin_traceon): ditto.
3463 (builtin_traceoff): ditto.
3464 Reported by Akim Demaille <akim@epita.fr>
3466 * m4/Makefile.am (pkgincdir): Deleted. Use automake's built in
3467 pkgincludedir instead.

3490 makeinfo calculates them for us, and to make any future
3491 reorganisation easier.
3492 (Frozen files): Document format version 2.
3493 `V' now takes argument `2'.
3494 `F' can take a single argument if symbol and builtin names
3495 are the same, or 3 arguments if the builtin is from a module.
3496 New `S' specification for saving syntax table contents.
3497 New `M' specification for saving loaded module names.

3633 * src/m4.c (main): Assume interactive mode if STDIN is connected
3635 Changed startup sequence slightly so that syntax is not
3636 initialised from here when loading a frozen file.
3638 * src/builtin.c: Much improved macro definition style.
3639 * src/m4private.h: Internal structures for m4_builtin and

3646 external definition.

3651 odule defines an identical name.
3652 * src/symtab.c (remove_table_reference_symbols): remove all symbol
3653 table entries which refer to a given builtin table.

3675 * src/m4.c: initialize libltdl's preloaded symbols via
3676 LTDL_SET_PRELOADED_SYMBOLS
3677 * src/module.c: libltdl's memory management must be initialized
3678 before calling lt_dlinit!, fix warnings
3680 2000-01-18 Gary V. Vaughan <gary@gnu.org>
3682 * README: Caveat about nls not supported by dll architecture on
3685 * TODO (MODULE SPECIFIC ISSUES): more ideas for the future.
3687 * tests/Makefile.am (stamp-TESTS): now works with VPATH.
3688 * src/Makefile.am (m4_LDADD): use $(builddir) for VPATH.
3689 * modules/Makefile.am (LIBS): ditto.
3690 (INCLUDES): search $(top_srcdir) (for eg. <m4/error.h>) and then
3691 $(top_srcdir)/m4 (for only <m4module.h>).
3692 * modules/shadow.test: fixed for VPATH.
3693 * modules/modtest.test: ditto.

3706 * acm4/ltdl.m4: Updated to latest from libtool cvs.
3707 * acm4/modules.m4: Remove code which duplicates ltdl.m4 and
3708 increment serial number.
3710 * Makefile.am (SUBDIRS): Moved @MODULES_DIR@ to compile before
3711 src dir and immediately after libm4 is built for confidence that
3712 it doesn't rely on the src directory.
3713 (SUBDIRS): Moved doc dir to the end since helptoman.pl and
3714 makeinfo stop the build on cygwin (because they don't work).
3716 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
3718 * m4/m4private.h: ...is not a public header, so moved to src.
3719 Add `#include <config.h>', `#define _COMPILING_M4' and
3721 * m4/Makefile.am (noinst_HEADERS): remove m4private.h.
3722 * src/Makefile.am (noinst_HEADERS): add m4private.h.
3723 * src/builtin.c: `#include "m4private.h"' now takes care of the
3724 above. Duplicates removed.
3725 * src/debug.c: ditto.
3726 * src/eval.c: ditto.
3727 * src/evalmp.c: ditto.

3741 * m4/Makefile.am (CLEANFILES): @EXEEXT@ left libtool wrapper behind.
3742 (INCLUDES): Look first in $(top_srcdir) (for eg. <m4/error.h>),
3743 and then in $(top_srcdir)/lib (for eg. "m4private.h").
3744 * src/Makefile.am (m4_LDADD): replace libi/libm4.la with
3746 * m4/m4error.h: Renamed error.h, for installation to
3747 $prefix/include/m4..
3748 * m4/m4obstack.h: Renamed obstack.h, for same reason.
3749 * m4/m4regex.h: Renamed regex.h, for same reason.

3762 From Akim Demaille <akim@epita.fr>
3764 2000-01-17 Gary V. Vaughan <gary@gnu.org>
3766 * src/ltdl.c: Use access() to abort doomed module load attempts
3767 if module file does not exist.
3769 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
3770 getopt1.o will already be used if appropriate, so I moved getopt.c
3771 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
3773 * modules/modpath1.test: Use correct filename in header line.
3774 * modules/modpath2.test: ditto.
3775 * modules/modpath3.test: ditto.
3776 * modules/modpath4.test: ditto.
3778 Without these changes lt_dlopen("test") attempts to
3779 LoadLibrary("/bin/test") on Windows, which although harmless
3780 generates a spurious error message which spoils most of the tests:
3781 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
3782 (TESTS): s/test.test /modtest.test /
3783 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /
3784 (test_la_SOURCES, test_la_LDFLAGS): renamed to use modtest.
3785 * modules/modpath1.test: s/test.m4 /modtest.m4 /
3786 * modules/modpath2.test: ditto.
3787 * modules/modpath4.test: ditto.
3788 * modules/modpath3.test: s/-m test /-m modtest /
3789 * modules/shadow.m4: use {un,}loadmodule(`modtest').
3791 2000-01-16 Gary V. Vaughan <gary@gnu.org>
3793 * src/ltdl.c (find_file): Updated to new version with fixed memory
3794 allocation bug in `next'.
3795 * src/ltdl.h: updated to match.
3797 * modules/Makefile.am: Cleaned up and reordered.
3799 2000-01-16 Rene' Seindal <rene@seindal.dk>
3801 * modules/Makefile.am (TESTS): New tests for the module system.
3803 * modules/*.test: New files.
3805 * src/m4.c (main): Added call to module_init().
3806 Treats -M and -m as the arguments -D -U and -t, ie deferred.
3808 * src/m4.h: Added declaration of module_init().
3810 * src/module.c (module_init): No longer static
3812 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
3813 Added to shut up automake about non standard libtool library
3816 * src/module.c: Disabled DEBUG by default.
3818 * modules/README: Changed example from unload.m4 to shadow.m4
3820 * modules/shadow.m4: Renamed from unload.m4
3822 * modules/Makefile.am (EXTRA_DIST): Removed unload.m4.
3824 * src/m4.c (main): Functionality for -m and -M were reversed.
3827 2000-01-12 Gary V. Vaughan <gary@gnu.org>
3829 * doc/help2man.pl: updated to version 1.020.
3831 * lib/COPYING.LIB: updated to version 2.1.
3833 * lib/m4module.h: restructure the M4_SCOPE code to work when
3834 creating a dll which links with libm4.la and both DLL_EXPORT
3835 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
3838 2000-01-11 Gary V. Vaughan <gary@gnu.org>
3840 Merged the following changes from my tree:
3842 1999-06-15 Gary V. Vaughan <gary@gnu.org>
3844 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
3845 ported to compile shared libs.
3847 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
3848 use `__declspec(dllimport)' when linking libm4.la on win32.
3849 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
3851 * configure.in (M4OBJS): Discover whether we need the shipped
3852 implementation of getopt_long.
3853 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
3854 main binary here, as opposed to the module library in lib/libm4.la.
3856 1999-06-14 Gary V. Vaughan <gary@gnu.org>
3858 * modules/README: Updated to describe the improved libltdl based
3860 * README (cygwin): Added some compilation notes for building m4
3861 correctly under cygwin.
3862 * TODO: Cleaned out the entries for the module system since they
3863 are now implemented.
3865 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
3866 all instances of __P with M4_PARAMS.
3868 * lib/getdate.h: removed unreferenced file.
3870 * lib/m4private.h: New file to define the private interface to the
3871 token_data struct, which must be shared between m4module.c, and
3872 builtin.c but not exported to modules built from the installed
3873 m4module.h since it's size changes depending on compile time
3876 * src/m4.h: Lots of stuff moved to lib/m4module.h.
3878 * lib/m4module.h: New file to define the interface available when
3879 compiling m4 modules.
3880 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
3881 necessary for module compilation into this new file.
3883 * lib/Makefile.am (include_HEADERS): install headers (renamed to
3884 avoid nameclash with other system headers) necessary for compiling
3886 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
3887 so that modules can include the (renamed) installed headers and
3888 be guaranteed a matching implementation.
3889 * lib/m4error.h: renamed from error.h.
3890 * lib/m4obstack.h: renamed from obstack.h.
3891 * lib/m4regex.h: renamed from regex.h.
3892 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
3893 implementation, simply include the shipped version
3894 unconditionally, otherwise it is hard for a module to know
3895 whether the m4obstack.h header it is using matches the
3896 implementation it ends up linking against.
3897 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
3900 1999-05-18 Gary V. Vaughan <gary@gnu.org>
3902 * examples/misc.test: Don't run this test on machines which don't
3903 have a root user in /etc/passwd (e.g. cygwin).
3905 * tests/get-them (/^@example$/): Error messages might have a
3906 ``.exe'' suffix to the program name, or else use the libtool
3907 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
3908 of these cases are now catered for when comparing error messages
3910 * tests/other-tests/*.test: ditto.
3911 * examples/*.test: ditto.
3913 * tests/defs (M4): use libtool execute mode.
3914 * examples/defs (M4): ditto.
3916 * tests/get-them (END): explicitly close any open file.
3917 (printthem): In a regular expression, '{' is the start of a repeat
3918 count! Use `[{]' for a literal open brace.
3919 (/^@node /): Don't use substr on a string shorter than the trim
3922 1999-05-17 Gary V. Vaughan <gary@gnu.org>
3924 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
3926 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
3928 2000-01-10 Andreas Schwab <schwab@suse.de>
3930 * tests/other-tests/gmp.test: Find config.sh in build directory.
3932 * configure.in: Find tests/mkconfig.sh in $srcdir.
3934 * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in
3935 <signal.h> (for SUS2 compliant systems).
3937 * src/stackovf.c: Check for HAVE_SIGINFO_T in addition to
3940 2000-01-10 Rene' Seindal <rene@seindal.dk>
3944 * TODO, NEWS: Cleaned up and updated.
3946 * src/m4.c (main): New variable exit_status for exit status in
3947 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
3948 file cannot be read instead of EXIT_SUCCESS.
3950 * src/builtin.c (m4_indir): Changed error message to help
3951 translators (from Akim Demaille <demaille@inf.enst.fr>).
3953 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
3956 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
3959 * src/input.c (match_input): Reordering of code, to avoid multiple
3960 calls to push_string_init() from obstack_grow(), which can happen
3961 with some compilers (found and fixed by James Bonfield
3962 <jkb@mrc-lmb.cam.ac.uk>).
3964 * src/stackovf.c: Added prototypes for ultrix.
3965 (setup_stackovf_trap): Added __P to cast.
3966 (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>)
3968 2000-01-09 Rene' Seindal <rene@seindal.dk>
3970 * doc/m4.texinfo (Changequote): Added comment about changing
3971 quotes when the old quote is a part of the new.
3973 * src/builtin.c (expand_ranges): Added break after trailing dash.
3974 This caused misbehavious on some systems (found and fixed by Akim
3975 Demaille <demaille@inf.enst.fr>).
3977 * AUTHORS: Thomas Tanner included
3979 * acconfig.h: Added entry for ss_sp (see below).
3981 * configure.in (use_stackovf): Added check for stack_t with member
3982 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert
3983 <eggert@twinsun.com>).
3985 * doc/m4.texinfo (Frozen files): Added a simpler example for
3986 generating frozen files from several input files.
3988 1999-11-14 Paul Eggert <eggert@twinsun.com>
3990 * po/POTFILES.in: Add lib/getopt.c, lib/obstack.c,
3991 lib/regex.c, lib/xmalloc.c.
3993 1999-11-10 Rene' Seindal <rene@seindal.dk>
3995 * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal.
3997 * src/module.c: reindented.
3998 (module_load): return if this is a repeated load of same module.
3999 (module_init): slight change of logic to avoid repeated
4000 initialisation debug messages.
4002 * Makefile.am (DIST_SUBDIRS): Added to ensure modules/ is included
4003 in the distribution.
4005 * modules/Makefile.am (test_la_LDFLAGS): set to -module to silence
4006 automake warnings about missing lib prefix.
4007 (time_la_LDFLAGS): ditto
4008 (stdlib_la_LDFLAGS): ditto
4010 1999-11-10 Paul Eggert <eggert@twinsun.com>
4012 * src/m4.h: Include error.h, since our macros use error.
4013 * src/m4.c: Don't need to include error.h.
4015 1999-11-09 Paul Eggert <eggert@twinsun.com>
4017 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
4018 and zero, as Solaris 7 cc does.
4019 (bcopy): Remove macro; no longer needed with new obstack.h.
4021 * src/output.c (freeze_diversions): Don't assume that a
4022 diversion size can fit in `int'. Check for diversion file
4023 size too large to be printed with `unsigned long'.
4025 * src/Makefile.am (CFLAGS): Omit -Wall.
4027 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.
4029 * src/debug.c (trace_format):
4030 Use ANSI C if (defined __STDC__ && __STDC__) || defined PROTOTYPES.
4032 * src/freeze.c (produce_frozen_state):
4033 Don't assume string lengths fit in int.
4035 1999-10-13 Rene' Seindal <rene@seindal.dk>

4043 * src/module.c: entirely new implementation using libltdl.
4044 * po/POTFILES.in: added src/module.c.
4045 * modules/Makefile.am (LTLIBRARIES): Removed lib prefix as these
4046 are modules, not linktime libraries.
4047 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
4048 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
4049 avoidance on exported symbols.
4050 * modules/test.c (m4_macro_table, m4_init_module,
4051 m4_finish_module): ditto.
4052 * modules/time.c (m4_macro_table): ditto.
4054 * modules/time2.m4: new file which requires command line loading
4056 * src/m4.c (--load-module): dynamically load named runtime module
4057 into running executable before reading the source.
4058 (--module-directory): prepend a directory to the module search
4060 (module_init()): Do this the first time we load a module instead;
4061 if the module subsystem is broken normal m4 scripts can still run.
4062 * src/m4.h (install_builtin_table): is now exported.
4064 1999-03-26 Gary V. Vaughan <gary@gnu.org>
4066 * src/module.c: removed. No longer required.

4077 * src/Makefile.am (MAINTAINERCLEANFILES): ditto.
4078 * tests/Makefile.am (MAINTAINERCLEANFILES): ditto.
4080 * acinclude.m4: removed. `aclocal -I acm4' handles this much
4082 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
4083 * acm4/gettext.m4: removed. It causes a multiple definition vs.
4084 the installed gettext.m4 file when running aclocal.
4086 1999-03-25 Gary V. Vaughan <gary@gnu.org>
4088 * configure.in (AM_INIT_AUTOMAKE): bumped version number to
4089 distinguish this from the last prerelease.
4090 (AC_LIBLTDL_CONVENIENCE): build libltdl as a convenience library
4091 in its own subdirectory.
4093 * modules/Makefile.am (*_SOURCES): renamed to use libtool's "no
4094 lib prefix on a module" feature.
4095 (LDFLAGS): Added `-module -avoid-version' flags to build
4096 versionless module libraries.
4097 * src/builtin.c (m4_load_module): use libltdl.
4098 (module_unload_all): use libltdl.
4099 * src/m4.c (module_init): initialise module loading on demand for
4100 better diagnostics, and so that m4 will still work even if
4101 the module code is broken.
4102 * src/m4.h (module_init): removed. No longer relevant.
4103 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on
4104 exported symbols for compatibility with dlpreopening.
4105 * modules/test.c (m4_macro_table, m4_init_module,
4106 m4_finish_module): ditto.
4107 * modules/time.c (m4_macro_table): ditto.
4109 * bootstrap: New file. Runs all the autoutils in the right order
4110 after a fresh checkout, or a make maintainer-clean.
4112 1999-02-18 Akim Demaille <demaille@inf.enst.fr>
4114 * src/builtin.c (dump_symbols): New function, factoring common
4115 content of m4_dumpdef and m4_symbols.
4116 (m4_dumpdef): Use it.
4117 (m4_symbols): New function, implementing `symbols'. Use it.
4118 * doc/m4.texinfo: Fixed missing commas after @xref, so that the
4119 file compile with modern makeinfo.
4120 (Symbols): New node, documenting symbols.
4121 (direntry): Modernize.
4123 1998-12-11 Rene' Seindal <rene@seindal.dk>
4125 * src/builtin.c (predefined_tab): New predefined macros
4126 __m4_changeword__, __m4_gmp__ and __m4_modules__ for testing for
4127 configure time options.
4129 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
4131 * src/module.c (module_try_load): Don't try to be clever and
4132 overwrite argument string. Instead allocate all constructed
4133 strings locally, since they can have arbitrary lengths. Make
4134 arguments pointers to const.
4135 (module_search): Simplify due to above change.
4137 1998-11-29 Rene' Seindal <rene@seindal.dk>
4141 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): New tests.
4143 * tests/other-tests/import-environment.{m4,test}: New test.
4145 * tests/other-tests/discard-comments.{m4,test}: New test.
4147 * doc/m4.texinfo (Invoking m4): Updated for --discard-comments.
4149 * src/m4.c (main): New option -c --discard-comments.
4150 New global variable discard_comments.
4152 * src/m4.h (token_type): New TOKEN_NONE for tokens to be
4153 discarded, ie never returned from next_token().
4154 Added declaration of discard_comments.
4156 * src/input.c (next_token): Now loops until token type is not
4157 TOKEN_NONE. Comments are now given this type when comments should
4160 * doc/m4.texinfo (Invoking m4): Updated for --import-environment
4163 1998-11-28 Rene' Seindal <rene@seindal.dk>
4165 * src/m4.c (main): New option --import-environment (no single
4168 * When configured with --with-gmp both the normal (fast) eval()
4169 and the gmp aware mpeval() are defined. To restore previous
4170 bahaviour use "define(`eval', defn(`mpeval'))".
4172 * tests/other-tests/gmp.m4: Changed to use mpeval().
4174 * src/evalmp.c: New file for compiling eval.c as gmp aware.
4175 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
4177 * src/eval.c: Now includes "numb.c" directly. Everything in this
4178 file must by static, except evaluate(), which is changed to
4179 mp_evaluate() if USE_GMP in force.
4181 * src/numb.c: Changed to be included by eval.c instead of being
4182 compiled separately. Everything is declared static.
4184 * src/numb.h: Removed declarations of functions, as numb.c is now
4187 * src/builtin.c: Declaration of m4_mpeval() added.
4188 Inserted `mpeval' in builtin table.
4189 (do_eval): New function with common code for m4_eval and m4_mpeval.
4190 (m4_mpeval): New function for gmp version of eval.
4192 * src/m4.h: Declaration of mp_evaluate().
4194 * src/Makefile.am (m4_SOUCES): Includes mpeval.c.
4195 (EXTRA_m4_SOURCES): Now has numb.c and numb.h
4197 * src/m4.c (main): m4 --version also shows which options were used
4198 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
4200 1998-11-27 Rene' Seindal <rene@seindal.dk>
4202 * Error messages now always print program name before input file
4203 name as specified by GNU coding standards. Reported by Akim
4204 Demaille <demaille@inf.enst.fr>.
4206 * doc/m4.texinfo (Include): Change due to changed error message
4210 * tests/get-them: Minor change to sed script due to changed error
4213 * src/m4.c (print_program_name): New func used to print program
4214 name, input file and line number in error (). Used as an
4215 error_print_progname handler.
4216 (reference_error): Removed.
4217 (main): Assigns error_print_progname.
4219 * src/m4.h (M4ERROR): Removed reference_error ().
4221 1998-11-25 Rene' Seindal <rene@seindal.dk>
4223 * Updated to libtool 1.2b.
4225 * src/builtin.c (install_builtin_table): Added braces to avoid
4226 warning of ambiguous 'else'.
4228 * src/module.c: Inserted search path code from path.c modified to
4230 (module_init): Configured default path used only if M4MODPATH is
4232 (module_try_load): Now reads libMODULE.la as generated by libtool
4233 for actual module name.
4234 (module_load): Gives better error messages on failure.

4240 functions of more generic search path handling.
4242 1998-11-24 Rene' Seindal <rene@seindal.dk>
4244 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
4245 included gettext, as <libintl.h> might not be found
4246 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
4248 1998-11-22 Rene' Seindal <rene@seindal.dk>
4250 * src/output.c (insert_diversion): Fixed bug that might cause m4
4251 to read from standard output! Triggered by input
4252 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
4253 so now 'undivert(0)' does nothing.
4255 1998-11-18 Rene' Seindal <rene@seindal.dk>
4259 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
4260 could be changed when compiling a illegal regexp, causing later
4261 use of the regexp to dump core.
4263 * src/module.c (module_load): Changed error message to conform to
4266 * src/m4.c (usage): Added message about reporting bugs.
4268 * doc/m4.texinfo (Changeword): Corrected a wrong example.
4269 (Changeword): Added note about the type of regexps used.

4280 libtool. The modules are compiled as shared libraries, and are
4281 renamed when installed.
4283 * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
4284 USE_SHL_LOAD to HAVE_SHL_LOAD
4286 * src/builtin.c (shipout_string): Now tests for a NULL string.

4290 portable parts better and to reduce the number of #ifdefs in the
4293 * Makefile.am (DIST_SUBDIRS): Instead of EXTRA_DIST for added
4294 directory modules/ to the distribution.
4296 1998-11-15 Rene' Seindal <rene@seindal.dk>

4301 functions: getcwd, getlogin, getpid, getppid, getuid, getpwnam,
4302 getpwuid, hostname, rand, srand, getenv, setenv, unsetenv, uname.
4304 * src/builtin.c (shipout_string): New convenience function for
4305 builtins and modules.
4307 * src/module.c (module_load): Tentative support for
4308 shl_load/shl_findsym, but I cannot test it. Copied from MetaHTML.

4312 * modules/Makefile.am: Now correctly compiles and installs
4313 modules in pkglibexecdir.
4315 * src/m4.h: WITH_MODULES defined iff HAVE_DLOPEN or USE_SHL_LOAD.
4316 These two are now initialised by autoconf macros.
4318 * src/path.c (module_env_init): MODULE_PATH is always on the
4321 * src/Makefile.am: Now generated pathconf.h which defined the
4322 default MODULE_PATH.
4324 * configure.in (pkglibexecdir): Added defintion of pkglibexecdir,
4325 where modules are installed.
4327 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
4328 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
4329 build and install automatically, and it is prepared for other
4330 interfacec than dlopen().
4332 * src/builtin.c (predefined_tab): Added __m4_version__ for the
4333 current version of GNU m4. It is a GNU extension.
4335 1998-11-14 Rene' Seindal <rene@seindal.dk>
4337 * tests/Makefile.am (GENERATED_TESTS): Added new
4338 generated-tests/changesy.8.test

4365 * tests/Makefile.am (GENERATED_TESTS): Renamed gentest to
4368 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): Added manually
4369 maintained tests in tests/other-tests. These currently tests for
4370 8-bit transparency, multiple precision arithmetic and sync-line
4371 output. Test for stackoverflow detection does not work.
4373 * examples/Makefile.am (TESTS): Added tests for all example files.
4375 * examples/mktests.sh: New file. Help program for creating test
4378 * tests/mkconfig.sh: New file to generate tests/config.m4 and

4405 * AUTHORS, ChangeLog: Changed all dates to ISO 8601.
4407 * intl/: Updated to GNU gettext 0.10.35.
4409 * doc/m4.texinfo (Format): Documented that format is blind.
4411 * src/builtin.c (builtin_tab): Builtin format marked as blind.
4413 1998-10-07 René Seindal <rene@seindal.dk>
4417 * tests/Makefile.am (GENERATED_TESTS): Changed .m4 extension to
4418 .test, as the files are no longer just m4 input.
4420 * tests/get-them (FILE): Changed .m4 extension to .test.
4422 * src/m4.h (token_type): New token type TOKEN_SPACE introduced.
4423 Otherwise quoted strings with leading whitespace first in a macro

4426 * src/macro.c (expand_token): Handles new token type TOKEN_SPACE.
4427 (expand_argument): Do.
4429 * src/input.c (next_token): SPACE and NUM/OTHER characters are only
4430 grouped together iff both quote and comment strings are single
4431 character. Otherwise they might include a comment/quote leader.
4432 (next_token): Returns new token type TOKEN_SPACE.
4434 * src/builtin.c (push_builtin_table): New function to push a
4435 builtin_table on the stack without installing its contents.
4436 (find_builtin_by_name): Added call to push_builtin_table() if
4437 reading frozen files. Otherwise the builtins named in the frozen
4438 files could not be found.

4441 1998-10-04 René Seindal <rene@seindal.dk>
4445 * configure.in (ALL_LINGUAS): Added Polish pl.po
4447 1998-10-03 René Seindal <rene@seindal.dk>
4449 * Many files: Incorporated changes to implement dynamic modules.

4457 * src/builtin.h: New file, declares some functions from builtin.c
4458 that are of use for other modules (shipout_int, numeric_arg,
4459 skip_space, bad_argc), and the macros ARG() and DECLARE().
4461 * src/builtin.c (install_builtin_table): New function. Each
4462 module brings in a builtin_table, which is pushed on a stack.
4463 (struct builtin_table): New struct for list of builtin_tables.
4464 (m4_loadmodule): New function to implement builtin "loadmodule".
4465 (shipout_int): No longer static, to be used by modules.

4473 * src/path.c: Reorganised to allow for two search paths, one for
4474 include files and one for modules.
4476 * src/m4.h: Added declarations for new functions in module.c and
4479 * src/m4.c (main): Added call to module_init().
4481 * modules: New directory with a few demo modules.
4483 * Makefile.am (EXTRA_DIST): Added modules/* since modules/ is not
4486 * configure.in: Added modules/Makefile to AC_OUTPUT.
4488 * configure.in: Added code to implement --with-modules. Tests for
4491 * acconfig.h: Added WITH_MODULES
4493 1998-10-02 René Seindal <rene@seindal.dk>
4495 * examples/Makefile.am (pkgdata_DATA): Removed special target for
4496 check and variables TESTS. These tests are now run from the
4499 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
4500 directory. The files stay there but the tests are run from the
4503 * tests/Makefile.am (EXTRA_DIST): Added run-test.
4505 * tests/run-test: New file. Run a test manually
4507 * tests/Makefile.am, tests/get_them: Moved automatically generated
4508 tests (from the manual) to sub directory tests/gentest/. The
4509 tests/ directory had gotten a bit messy.
4511 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4513 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\
4514 wrap}.test: Added a few testcases.
4516 1998-08-21 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4520 * lib/Makefile.am (noinst_HEADERS): regex.h added
4522 * configure.in (jm_WITH_REGEX, jm_PREREQ_ERROR):
4523 acm4/{error,regex}.m4 (from fileutils-3.16u.tar.gz).
4525 * acm4/Makefile.am: created providing rules to create
4526 $(top_srcdir)/acinclude.m4 to be used by aclocal.
4528 * tests/defs (LANGUAGE, LC_ALL, LANG): force them to be
4529 `C'. Reported by Ulrich Drepper.
4531 * Makefile.am (SUBDIRS): Removed checks directory
4532 * configure.in (AC_OUTPUT): Removed checks/Makefile
4534 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
4535 the space when m4.texinfo is edited and whitespace.el is active.
4536 (Defn,example): idem.
4538 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4540 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
4541 ../COPYING. ../Makefile is a file which is certainly present when
4542 test is executed in testSubDir. One can't be sure that the COPYING
4543 file is in .. or ../.. in all situations, the ../Makefile is
4546 * doc/m4.texinfo (Include): adjusted expected test output
4547 according to new tests, i.e. the input will always come from the
4548 file `in' created by the test.
4550 * tests/Makefile.am: Added three lines at the top to get
4551 esyscmd.1.test working.
4553 * tests/get-them: modified to generate clearer tests who will need
4554 less maintenance when new test examples are created in
4555 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
4556 need the generic file `defs') shell scripts creating `in', `ok',
4557 `out' and when apropriate `okerr' and `err' in the directory
4558 `testSubDir' when executed. The compare of `ok' and `out'
4559 (and of `okerr' and `err') will be the exit status of the test.
4560 `out' must match `ok' (and `okerr' must match `err') for the test
4563 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
4564 the tests generated by tests/get-them getting it input normally
4565 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
4566 (dot) before the numeric part) is reserved for all other (hand
4567 written) tests. The `+' means one or more times.
4569 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4571 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
4572 supported short man page to refer to info documentation
4573 * helptoman.pl: added
4574 * configure.in: AC_PATH_PROG(PERL,perl)
4575 * Makefile.am (SUBDIRS): doc after src
4577 * libitized with libit 0.5 from
4578 ftp://ftp.iro.umontreal.ca/pub/contrib/pinard/maintenance/libit.

4598 * src/builtin.c (m4_changesyntax): Added builtin macro
4599 "changesyntax" to modify the syntax table.
4601 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax
4602 table. All categories are assigned a syntax code and tokens are
4603 read according to this table.
4605 1998-08-09 René Seindal <rene@seindal.dk>
4607 * src/numb.{c,h}: New files, implements multiple precision eval
4608 using GNU gmp. Originally submitted by John Gerard Makecki
4609 (johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.
4611 * doc/m4.texinfo (Eval): Added documentation for multiple
4612 precision arithmetic library support.
4614 * src/m4.{c,h}, src/eval.c, src/builtin.c, configure.in: Changes
4615 to accommodate multiple precision eval.
4617 1998-08-07 René Seindal <rene@seindal.dk>
4619 * src/input.c (MATCH, match_input), src/m4.h: changed definition
4620 of comment and quote strings to `unsigned int' to allow eight bit
4621 chars (reported by andrewb@zip.com.au (Andrew Bettison)).
4623 * src/builtin.c, doc/m4.texinfo: Builtin `syncoutput' added by
4624 patch from Mike Howard <mike@clove.com>
4626 1998-08-06 René Seindal <rene@seindal.dk>
4628 * gettext.m4: corrected AM_WITH_NLS to handle use of installed
4631 1998-08-03 René Seindal <rene@seindal.dk>
4635 * src/m4.h: Added ifdef ENABLE_NLS around include of <libintl.h>
4636 and _ macro. M4 now builds with --disable-nls.
4638 * src/m4.c (main): reintroduced textdomain(PACKAGE) to get gettext
4639 to look for right message catalogs. Call indef'ed by ENABLE_NLS.
4641 * configure.in (ALL_LINGUAS): Added complete list of translations:
4642 de fr it ja nl ru sv.
4644 1998-05-22 Erick Branderhorst <Erick.Branderhorst@asml.nl>
4648 * src/m4.c: #include <signal.h> not <sys/signal.h>.
4650 * src/Makefile.am: CFLAGS = -Wall @CFLAGS@.
4652 * checks/Makefile.am: explicit list tests in CHECKS.
4654 * configure.in, {,src,doc,lib,examples,checks}/Makefile.am,
4655 src/{ansi2knr.{1,c}} doc/{m4.texinfo,mdate-sh}, missing,

4660 Used libitize (0.4) to update.
4662 * configure.in, ABOUT-NLS, intl/*, po/*: Added gettextize
4663 (0.10.25) support. Removed LOCALE, fr.msg, m4.cod and adjusted
4666 * src/stackovf.c: #ifdef USE_STACKOVF ... #endif to (de-)activate
4667 stack overflow functionality.

4687 src/stackovf.c: Rename _ to __P.
4688 * src/m4.h: Declare _ as a macro returning its argument, or else,
4689 include <libintl.h> and declare _ as gettext.
4690 * src/m4.c: Possibly include <locale.h> and call setlocale.
4691 * src/m4.c, src/builtin.c, src/debug.c, src/eval.c, src/freeze.c,
4692 src/input.c, src/macro.c, src/output.c, src/path.c,

4714 be opened, return immediately after producing the error message.
4715 Reported by Andreas Schwab.
4717 * configure.in: Check for const only after having found possible
4718 ANSIfying compiler flags, this is of no use to check it before.
4719 Reported by Alexander Lehmann.
4721 1994-11-01 François Pinard <pinard@iro.umontreal.ca>
4723 * src/macro.c (collect_arguments): Cast obstack arguments to
4724 (voidstar), so avoiding compiler warnings.
4725 Reported by Joseph E. Sacco.
4727 * src/freeze.c (produce_frozen_state): Cast printed lengths to
4728 (int) so they correspond to %d format items.
4729 Reported by Joseph E. Sacco.
4731 * src/m4.c (main): Cast the argument to xfree to (voidstar).
4732 * src/symtab.c (free_symbol): Idem.

4744 1994-10-30 François Pinard <pinard@iro.umontreal.ca>
4746 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
4747 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
4748 defines __STDC__ to 0, for indicating it is *not* ANSI!
4749 Reported by Kaveh R. Ghazi.
4751 * configure.in: Added obsolescent tests for AIX and Minix.
4753 * doc/Makefile.in (mostlyclean): Remove texclean in dependencies,

4766 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
4767 Remove the sed filter after ansi2knr for debug.c. Use $O instead
4768 of $U, put underline in extensions rather than in basenames. Use
4769 implicit rules, now that regularity makes this possible.
4770 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
4771 of ansi2knr whenever it is needed.
4772 * configure.in: Adjusted for correct STACKOVF substitution.
4773 * src/debug.c (trace_format): When not __STDC__, use (...) as a

4785 * Makefile.in (all, install, uninstall): Depend on Makefile.
4787 * Makefile.in: For actions invoking $(MAKE) from within compound

4792 * {,/*}Makefile.in: Use && after all cd, in case they fail.
4794 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

4818 * configure.in: Do not add -O to CFLAGS for GNU C, now that
4819 configure does it automatically.
4820 Reported by Jim Meyering.
4822 1994-09-23 François Pinard <pinard@iro.umontreal.ca>
4824 * src/stackovf.c: Declare the handler_t typedef earlier in the

4854 * Makefile.in: Make TAGS in lib also, not just in src.
4855 Reported by Karl Berry.
4857 * Makefile.in (distclean, realclean): Instead of recursively
4858 calling $(MAKE) for the -local part, allow parallel execution of
4859 -recursive and -local, only delay the removal of config.status,
4860 which is repeated in both goals.
4862 1994-09-13 François Pinard <pinard@iro.umontreal.ca>
4866 * Makefile.in: Group all *clean-recursive goals in one, using sed
4867 to remove `-recursive' while calling make recursively. Also, use
4868 a subshell for each recursive $(MAKE).
4869 Reported by Jim Meyering.
4871 * src/m4.h (memcpy): Define with bcopy for BSD systems.
4872 Reported by Kaveh R. Ghazi.
4874 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS

4930 Reported by Jim Meyering.
4932 Solidify frozen files with respect to -P:
4933 * src/m4.c: Have -P set prefix_all_buitins variable instead of
4934 calling a function by that name. Declare the variable.
4935 * src/m4.h: Adjust declaration for prefix_all_buitins.
4936 * src/builtin.c (builtin_init): Merge in functionality from
4937 previous prefix_all_buitins function, while making entries in the
4938 symbol table, but not modifying the builtin description itself.
4940 * src/freeze.c (reload_frozen_state): Add a useless `break;',
4941 because *many* compilers do not accept an empty `default:'.
4942 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
4943 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
4945 * configure.in: Use AC_TYPE_SIGNAL.

4955 functions, for implementing a global MAXIMUM_TOTAL_SIZE instead of
4956 a per buffer MAXIMUM_BUFFER_SIZE.
4958 * src/output.c (output_text): New function, for optimizing the
4959 output of strings of characters. Use it.
4961 1994-08-30 François Pinard <pinard@iro.umontreal.ca>
4963 * doc, src: New directories reorganizing the distribution.

4966 * Makefile.in: Adjusted.
4967 * configure.in: Configure new Makefiles.
4969 * m4.h: Declare STRING typedef. Use it for comment and quote
4970 strings, adjusting all references. (This is the rudiments of a
4971 beginning for the eventual withdrawal of NUL terminated strings.)
4972 * output.c (shipout_text): Accept a length parameter, and use it.
4973 All callers adjusted.
4975 1994-08-29 François Pinard <pinard@iro.umontreal.ca>
4977 * m4.h: Include <unistd.h> if it exists.

4993 * m4.c: Still accept -N, but do nothing with it.
4994 Reported by David MacKenzie.
4997 * output.c (freeze_diversions): New function.
4998 * m4.h: Declare freeze_diversions.
4999 * freeze.c: Document frozen file format, revise it, call
5000 freeze_diversions to add diversions to frozen format, and code to
5001 reload them properly.
5002 * m4.c: Do not undivert automatically at end when status being
5003 frozen. Do not call builtin_init when reloading frozen state.
5005 Speed up diversion processing:
5006 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
5007 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
5008 structure and variables, cached variables out of output_diversion,
5009 reallocate_diversion_for and OUTPUT_CHARACTER.
5010 (shipout_text, make_diversion, insert_diversion): Adapted to new

5018 dist works from another build directory.
5020 1994-08-27 François Pinard <pinard@iro.umontreal.ca>
5022 * symtab.c (hack_all_symbols): Use hash_table_size instead of

5025 * builtin.c (DECLARE): Simplify by using _ ().
5027 * freeze.c: New file.
5028 * Makefile.in: Compile it, distribute it.
5029 * m4.c: Recognize, document and process --freeze-state (-F) and
5030 --reload-state (-R) options. Pass a true flag to builtin_init
5031 only if no reloading some state.
5032 * builtin.c (define_builtin): Remove static specifier.
5033 (find_builtin_by_name): Remove static specifier.

5049 Reported by Akiko Matsushita.
5051 1994-08-12 François Pinard <pinard@iro.umontreal.ca>
5053 * m4.h: Include <sys/types.h>.
5054 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
5055 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
5057 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
5059 * builtin.c (dump_args): Declare len as size_t, not int.
5061 * debug.c: Prototype the forward declaration of debug_set_file.
5063 * builtin.c (m4_undivert): Replace div by file, for avoiding the
5064 shadowing of this variable.
5065 * output.c (insert_diversion): Idem.
5067 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
5068 (input_init): Duplicate default quote and comment strings.

5075 * Makefile.in (distclean-local): Also delete config.cache.
5077 * m4.c (usage): Reorganize the --help output by topic. Include a
5078 description for debugging flags.
5080 1994-07-29 François Pinard <pinard@iro.umontreal.ca>
5082 * configure.in: If sigaction is available and SA_ONSTACK defined,
5083 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
5084 defined, use sigvec. Else don't compile stackovf.c.
5085 * stackovf.c (setup_stackovf_trap): Idem.
5086 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
5089 1994-07-21 François Pinard <pinard@iro.umontreal.ca>

5093 1994-07-18 François Pinard <pinard@iro.umontreal.ca>
5097 1994-07-17 François Pinard <pinard@iro.umontreal.ca>
5099 * configure.in: Check for sigaction and sigvec. Add a new delayed
5100 check for RLIMIT_STACK, combine in the checking for getrlimit.
5101 All those things are not universally available.
5102 * stackovf.c: Split setting up the trap handler and catching
5103 signals, for better taking care of various configure outcomes.
5104 * examples/stackovf.sh: Correct a typo.
5105 Reported by Eric Backus, Jim Avera and Jim Meyering.
5107 1994-07-16 François Pinard <pinard@iro.umontreal.ca>
5109 * ansi2knr.c: New version sent by its author, Peter Deutsch.
5111 1994-07-15 François Pinard <pinard@iro.umontreal.ca>
5113 * Makefile.in: Modify so parallel make will not try making
5114 lib/libm4.a twice simultaneously.
5115 Reported by Jim Meyering.
5117 1994-07-14 François Pinard <pinard@iro.umontreal.ca>
5119 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
5120 error message, for when no code possibility exists. Even if this
5121 line is completely #ifdef'ed out, it brings a syntax error.
5122 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
5124 * Makefile.in (install): Have install depend on all too, for lib
5125 to be remade as needed.
5127 * examples/stackovf.sh: Try ksh, bsh and bash for shells
5128 providing ulimit, instead of using only ksh.
5129 Reported by Jim Avera and Joseph E. Sacco.
5131 1994-07-12 François Pinard <pinard@iro.umontreal.ca>
5133 * Makefile.in (check): Have it depend on all instead of m4. In
5134 this way, a change in lib will be detected and processed.
5136 * builtin.c (numeric_arg): Use strtol and verify the conversion,
5137 instead of using sscanf which stops as soon as there is a
5138 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
5139 and divert(1xyzzy) were all accepted without any warning or error
5141 * m4.h: Declare strtol as long if not including stdlib.h.
5142 * configure.in: Check for limits.h, and replace strtol if missing.
5143 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
5144 * lib/strtol.c: New file, from elsewhere.
5145 Reported by Andreas Schwab.
5147 1994-07-07 François Pinard <pinard@iro.umontreal.ca>
5149 * macro.c (expand_macro): Cast value to (boolean) prior to
5150 assigning it to traced.
5151 Reported by Tom McConnell.
5153 * Makefile.in (m4): Always make all in lib first.
5154 Reported by Jim Meyering.
5156 1994-07-06 Jim Avera <jima@netcom.com>
5158 * stackovf.c: Isolated OS-dependent sections; Improved portability,
5159 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
5160 handlers), and a default error message if the fault address is not
5161 available (when neither siginfo.h nor BSD sigcontext are supported).
5162 * configure.in: Changes for stackovf.h: Check for sigcontext,
5163 sigaction, sigstack, and define rlim_t as int if necessary.
5164 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
5165 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
5166 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
5168 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
5170 * configure.in: Use AC_SET_MAKE.
5171 * Makefile.in: Use @SET_MAKE@.

5175 Reported by Ian Taylor.
5177 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
5179 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
5180 because siginfo.h is unrelated to standard headers, and siginfo.h
5181 is already checked for.
5182 Reported by Joseph E. Sacco.
5184 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
5186 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
5189 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
5191 * builtin.c (substitute): Use \& to represent this part of the
5192 string which was matched by the whole regexp, instead of
5193 representing the whole string. Any usage of \0 issues a warning
5194 and acts like \&, it will disappear in some subsequent release.
5196 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
5198 * m4.c: Complete prototype for forwarded declaration of usage.
5200 * input.c (init_macro_token): Correct own reference in error
5201 message. Previous name get_macro_func was referred to instead.
5202 (next_char): Correct own reference in error message. Previous
5203 name advance_input was referred to instead.
5205 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
5206 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
5207 and_term, not_term, logical_not_term, cmp_term, shift_term,
5208 add_term, mult_term, exp_term, unary_term, simple_term): Add
5209 prototype to forwarded declarations. Declare parameter v1 as
5210 eval_t * instead of int *. Same for local variable v2 in dyadic
5211 functions. Same for result in exp_term.
5212 * builtin.c (m4_eval): Declare value as eval_t instead of int.
5213 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
5214 unsigned_eval_t instead of unsigned int. Change casts accordingly.
5215 (shipout_int): Cast first argument of ntoa to eval_t.
5216 Reported by Thorsten Ohl.
5218 * macro.c: Complete the prototypes of forwarded expand_macro and
5220 Reported by Thorsten Ohl.
5222 * m4.h: Define voidstar as void * or char * depending on __STDC__.
5223 The Ultrix 3.1 compiler cannot do much with void pointers.
5225 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
5226 * m4.c (xfree): Replace void * by voidstar.
5227 Reported by Tom McConnell.
5229 * ansi2knr.1: New, from elsewhere.
5230 * Makefile.in (DISTFILES): Distribute ansi2knr.1
5232 * Makefile.in (stamp-h.in): Avoid running ./config.status if
5233 stamp-h does not exist yet. This avoids running it a second time
5234 just after the initial ./configure.
5235 Reported by David MacKenzie and Tom McConnell.
5237 * m4.h: Replace the enum debug_info declaration with a series of
5238 #define's. The Ultrix 3.1 compiler would otherwise need casting
5239 (int) to most references, when used in expressions.
5240 Reported by Tom McConnell.
5242 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
5244 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
5245 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
5246 calls the compiler. Previously, FP_PROTOTYPES was only calling
5247 the preprocessor; by not being subject to CFLAGS, this was
5248 discouraging those flags asking for ANSI compilation.
5249 * acconfig.h: Document HAVE_PROTOTYPES.
5250 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
5251 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
5252 Reported by Eric Backus.
5254 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
5255 from the environment. Default CFLAGS to -g if not set.
5256 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
5257 * lib/Makefile.in: Have CFLAGS substituted from configure.
5258 Reported by Eric Backus and Tom McConnell.
5260 * configure.in: m4_undefine changeword before using AC_ENABLE.
5262 * m4.h: Declare prototypes for error (for ANSI compilers only),
5263 prefix_all_builtins and reference_error.
5264 Reported by Tom McConnell.
5266 * input.c (set_word_regexp): Do not try to initialize the array
5267 test from a string, this does not work with non-ANSI compilers.
5268 Reported by Eric Backus.
5270 * Makefile.in (dist): Clean examples/ before saving it.
5271 (distclean-local): Also remove stamp-h.
5272 Reported by Eric Backus.
5274 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
5276 Reported by Tom McConnell.
5278 * checks/Makefile.in (clean): Depends on mostlyclean.
5279 (mostlyclean): New goal.
5281 1994-06-24 François Pinard <pinard@iro.umontreal.ca>
5283 * Makefile.in (DISTFILES): Distribute install.sh.
5284 * install.sh: New file, copied from elsewhere.
5285 Reported by Assar Westerlund and Kaveh R. Ghazi.
5287 1994-06-23 François Pinard <pinard@iro.umontreal.ca>
5289 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
5290 * acconfig.h: Explain ENABLE_CHANGEWORD.
5292 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
5293 from code provided by Pete Chown]
5294 * m4.h: Add original_text field to u_t variant of union u.
5295 Declare TOKEN_DATA_FUNC macro.
5296 * builtin.c: Declare changeword.
5297 (m4_changeword): New function.
5298 * input.c: Include "regex.h", define variables with word regexps.
5299 (input_init): Initialize the word regexp.
5300 (set_word_regexp): New.
5301 (next_token): Declare local variables, use the previous code if
5302 default_word_regexp is true. Else, match using a new code. Save
5304 * macro.c (expand_token): Ship out original text if not a macro
5306 Reported by Krste Asanovic and Pete Chown.
5308 [These modifs all depend upon ENABLE_CHANGEWORD]
5309 * m4.h: Declare external user_word_regexp.

5313 DEFAULT_WORD_REGEXP.
5315 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
5318 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
5319 * checks/Makefile.in: Empty the suffix list.
5320 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
5322 * m4.c: Declare nesting_limit and initialize it to 250.
5323 Implement -LNUMBER or --nesting-limit=NUMBER to change its
5325 * m4.h: Declare nesting_limit as external.
5326 * macro.c (expand_macro): Stop execution whenever nesting limit
5328 Reported by Bengt Mertensson.
5330 * eval.c (evaluate): Diagnose excess characters in eval input.
5331 Things like `eval(08)' used to return 0 with no diagnostic.
5333 * m4.h: Capitalize first letter of all macro arguments in
5336 * m4.c: Declare warning_status, initialize it to 0. Add new
5337 option -E, or --fatal-warnings, which sets warning_status to
5338 EXIT_FAILURE instead.
5339 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
5340 EXIT_FAILURE if not otherwise done by header files.
5341 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
5342 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
5343 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first

5355 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
5356 also tested it on a Sun Sparc workstation running SunOS 4.x.
5358 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
5359 49.format check, abusing a `union values' argument with sprintf
5360 without selecting the proper field. Now, save the formatting type
5361 first, delaying the fetch of the corresponding argument.
5362 Reported by Joseph E. Sacco and Tom Quinn.
5364 * format.c (format): Remove const from char *fmt declaration when
5365 not HAVE_EFGCVT, because a NUL may be forced into it.
5367 * m4.h: Declare atof() when not STDC_HEADERS.
5368 Reported by Joseph E. Sacco.
5370 * Regenerate configure using Autoconf 1.11, this corrects a

5388 substitute ${U}stackovf.o for STACKOVF.
5389 * acconfig.h: Declare USE_STACKOVF.
5390 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
5391 * m4.h: Declare setup_stackovf_trap().
5392 * m4.c: Call setup_stackovf_trap().
5393 * tests/stackovf_test.sh: New file.
5395 1994-04-13 François Pinard <pinard@iro.umontreal.ca>
5397 * checks/Makefile.in: Rename .all-stamp to stamp-checks.

5408 Reported by Jim Meyering.
5410 * builtin.c (m4_regexp): Reorganize the code for avoiding a
5411 warning from gcc about `repl' possibly used before defined.
5412 Reported by Jim Meyering.
5414 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
5415 Reported by Jim Meyering.
5417 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
5419 * m4.h: Move the conditional definition of volatile after the
5420 inclusion of system files, because they may define it first.
5422 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
5424 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
5425 get around a problem with Alpha make seeing a syntax error, there.
5426 Reported by Vern Paxson.
5428 1994-01-03 François Pinard <pinard@iro.umontreal.ca>
5430 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.

5444 Use them in exit() and usage() calls.
5446 1993-11-27 François Pinard <pinard@iro.umontreal.ca>
5448 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
5449 syserr() macro. Delete errref, add reference_error and M4ERROR.
5450 * m4.c: Replace errref, which was returning an input reference
5451 string, with reference_error, which prints it on standard error.
5452 * builtin.c, output.c: Use errno as second parameter to error,
5453 instead of using syserr() with %s.
5454 * *.c: Use M4ERROR instead of error: no more errref() with %s.
5455 Doing so, the program name appears after the input reference
5456 instead of before, which eases M-x next-error processing.
5458 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
5460 * checks/get-them: Escape braces with backslashes in patterns,
5461 because HPUX-9.01 awk needs this.

5471 * m4.c: Delete error_message_prefix() function, add errref().
5472 * *.c: Use error() systematically in place of all error macros,
5473 now that error() flushes stdout first. Make needed adjustments.
5475 * m4.h: Remove const in sys_errlist[] declaration, it creates
5476 conflicts on SGI and Alpha.
5477 Reported by Kaveh R. Ghazi.

5497 * input.c (input_init): Initialize quote and comment strings
5498 explicitely instead of calling set_quotes and set_comment: by
5499 doing so, we ensure we do not free uninitialized variables.

5502 expected is on the left and the obtained on the right.
5504 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR

5506 internal_error, add declaration for error_message_prefix.
5507 * m4.c: Delete m4error, warning, fatal and internal_error
5508 routines, add error_message_prefix routine.
5509 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
5510 warning with WARNING*, fatal with FATAL* and internal_error with
5512 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
5513 this is not needed anymore.
5515 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
5516 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
5517 and debug_message, add declaration for debug_message_prefix.

5528 (trace_format): Use stdarg instead of varargs if __STDC__.
5530 * configure.in: Remove checks for vfprintf and _doprnt. These

5640 Reported by Jim Avera.
5642 * builtin.c (m4_ifelse): Diagnose excess arguments if 5, 8, 11,

5832 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
5834 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
5835 to diversion/DIVERSION, this was a spelling error.
5837 * m4.c: Declare version[], remove #include "version.h".
5838 * version.h: Deleted.
5839 * Makefile.in: Remove references to version.h.
5841 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
5842 production, by using a simpler and more robust algorithm. This
5843 solves the problem of synclines sometimes written in the middle of
5844 an output line. Delete sync_line() and output_lines variable.
5845 * m4.h: Remove sync_line prototype and output_lines declaration.
5846 * input.c (next_char), output.c (shipout_text): Remove references
5848 * input.c (push_file, pop_file): Merely put the value -1 in
5849 output_current_line instead of calling sync_line, for delaying a
5850 single `#line NUM FILE' before next output line. Do not test
5851 for sync_output, because this is unnecessary clutter.
5852 * output.c (make_divertion, insert_divertion): Idem.
5853 * input.c: Rename must_advance_line to start_of_input_line, for
5856 * debug.c (trace_header): Select a new debug line format, which
5857 better complies with GNU standards for formatting error messages.
5858 With option `-dfl', M-x next-error might be used on the output.
5859 * m4.c (vmesg): Adjust format of error output to GNU standards.
5860 * m4.texinfo: Adjust examples for `make check' to work.
5862 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
5863 case for enum debug_info constants, which were all lower case.
5865 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
5867 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
5868 collected patches. I tried a few times using newer regex.[ch], it
5869 mysteriously stopped aborting with this one. Insecure feeling...
5870 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
5872 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
5874 * m4.c: Change `--no-warnings' to `--silent'.
5875 Reported by David MacKenzie.
5877 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
5878 leave it off for now. See comment in m4.c for justification.
5879 Reported by David MacKenzie.
5881 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
5882 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
5884 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
5886 * Makefile.in: Ensure recursive cleaning is done before local
5887 cleaning for all clean goals.
5889 * builtin.c (ntoa): Ensure the value is always interpreted as a
5890 signed quantity, whatever the radix is.
5892 1992-11-18 Jim Meyering <meyering@idefix>
5894 * builtin.c, format.c, input.c: Split long lines.
5895 * m4.c: Use typedef macro_definition instead of struct
5897 * symtab.c: Use typedef symbol instead of struct symbol.
5899 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
5901 * *.[ch]: Remove all trailing whitespace, in code and comments.
5903 * configure.in: Find some awk.
5904 * Makefile.in: Add $(AWK) to MDEFINES.
5905 * checks/Makefile.in: Transmit $(AWK) to get_them.
5906 * checks/get_them: Use $AWK instead of gawk. Add a close in the
5907 awk script when switching files, because without this, mawk runs
5908 out of file descriptors.
5910 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
5912 * Makefile.in (realclean): Delete m4.info*.
5913 Reported by Jim Meyering.
5915 * Makefile.in: Adjust and link with checks/Makefile.
5916 * checks/Makefile.in: New.
5917 * configure.in: Output checks/Makefile.
5919 * checks/get_them: Have the dnl header of each test more
5920 recognizable by next-error, also use a better message.
5922 1992-11-16 Jim Meyering <meyering@idefix>
5924 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
5925 And use that only if __GNUC__ since we're using it's GCC-specific
5926 semantics that tell the compiler the associated function doesn't
5929 * builtin.c (substitute): Don't use character as an array index.
5930 (dumpdef_cmp): Make formal arguments `const void *' to avoid
5931 warnings with gcc -W -Wall on systems with qsort prototype.
5932 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
5935 * eval.c (most functions): Add parentheses to assignments used
5936 as truth values go avoid warnings from gcc -Wall.
5938 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
5939 any functions that don't need external scope.
5941 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
5942 (many functions and arrays): Declare `const'.
5944 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
5946 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
5947 removing the declaration from m4.h. Also rename false to FALSE
5950 * lib/Makefile.in (Makefile): New goal.
5952 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
5953 so heavily loaded. It gets more easily overridable, calling make.
5954 Reported by Jim Meyering.
5956 * Makefile.in (dist): Get .fname from the current directory name,
5957 instead of from version.h. I need updating many files manually,
5958 when the version changes, version.h is just one of them.
5960 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
5962 * m4.h: Remove the tag `boolean' on the enum introducing typedef
5963 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
5964 Reported by Tom McConnell.
5966 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
5968 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
5969 39.cleardiv, which were describing missing or spurious newlines.
5970 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
5971 do not depend on machine word size, `/bin/false' implementation,
5972 or `wc' output format. `make check' is more dependable, now.
5974 * checks/check_them: Summarize the failed tests by listing their
5975 name, at end. If none, issue `All checks successful'. Output
5976 `Checking' instead of `Input file:'.
5978 * checks/get_them, checks/check_them: Reindented.
5980 * Makefile.in (dist): chmod a+r before making the tar file.
5982 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
5984 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
5986 * input.c (next_token): Reinitialize token_buttom just after using
5987 it as a watermark with obstack_free. Or else, a future token, big
5988 enough for triggering reallocation of the obstack chunk, could
5989 void the initialized value of token_buttom, later causing panic in
5990 obstack_free. Rename token_buttom to token_bottom everywhere.
5992 * m4.h: Before declaring errno, first include <errno.h> and
5993 ensure that it does not define errno.
5994 Reported by Richard Stallman.
5996 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
5998 * builtin.c: Define and use DECLARE macro for builtins.
6000 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
6001 argument, this is a common idiom for introducing long comments.
6003 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
6004 arguments. The last argument was silently ignored.
6006 * m4.c (cmd_error): Add a missing semicolon before va_end().
6008 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
6010 * Makefile.in: Now handle protoized sources. Define and use U.
6011 Compile and use ansi2knr with old compilers. Update DISTFILES.
6012 Add `aclocal.m4' to `configure' dependencies.
6013 * ansi2knr.c: New, from Ghostscript distribution.
6014 * configure.in: Define U through FP_PROTOTYPES for old compilers.
6015 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
6016 * aclocal.m4: New, provide FP_PROTOTYPES.
6017 * m4.h: Conditionnaly protoized through Args, save for varags.
6018 * builtin.c: Protoized. Then:
6019 Include <sys/types.h> if size_t is not defined, before "regex.h".
6020 (m4_ifelse): Fetch built-in name properly for diagnostic.
6021 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
6022 (m4_regexp): Add const to `msg' declaration.
6023 (m4_patsubst): Add const to `msg' declaration.
6024 * debug.c: Protoized, save for varargs.
6025 * eval.c: Protoized.
6026 * format.c: Protoized.
6027 * input.c: Protoized.
6028 * m4.c: Protoized, save for varargs. Then:
6029 (xfree): Accept void * instead of char *.
6030 (xmalloc): Return void * instead of char *.
6031 (xrealloc): Accept and return void * instead of char *.
6032 * macro.c: Protoized.
6033 * output.c: Protoized.
6034 * path.c: Protoized. Then cast some (char *) over xmalloc's.
6035 * symtab.c: Protoized.
6037 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
6039 * m4.texinfo: Remove directory from diagnostics in 30.include,
6040 51.eval, 56.errprint and 57.m4exit tests.
6042 * m4.h: Remove declarations for int or void system functions, they
6043 cause more conflicting trouble than they make good.
6045 * configure.in: Avoid configuration header file. Add some tests.
6046 * m4.h: Remove #include "config.h".
6047 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
6048 Then, rewritten for better compliance with GNU standards.
6050 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
6052 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
6053 because of a misplaced #endif.
6055 * Many *.[hc] files: Correct intra-line spacing here and there,
6056 according to GNU indent 1.6 advice.
6058 * configure.in: New, using Autoconf 1.2.
6059 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
6060 * Delete old configure.in, configure, etc/configure.in,
6061 etc/configure, lib/configure.in, lib/configure and config/*.
6062 Reported by Jason Merrill.
6064 * symtab.c (hash): Change (char) NULL to '\0'.
6065 Reported by Jason Merrill.
6067 * Delete .vers, etc/newdist.sh, etc/newvers.sh and
6068 etc/nextvers.sh. Release numbers will be edited `by hand'.
6069 * version.h: De-automatize, force value in.
6071 * m4.c: Changes in order to use a newer getopt.h.
6072 Reported by David MacKenzie.
6074 * checks/: New name for examples/.
6075 * checks/get_them: New location for etc/get_examples.
6076 * checks/check_them: New location for etc/check_examples.
6077 * Makefile.in, checks/get_them, checks/check_them: Adjust.
6078 * lib/vfprintf.c: New location for etc/vfprintf.c.
6079 * Delete empty etc/.
6080 * examples/: New name for test/.
6082 1992-03-10 François Pinard <pinard@iro.umontreal.ca>
6084 * Makefile.in (check): Add m4 as dependency.
6086 * m4.c: Accept --no-warnings instead of --no_warnings, and
6087 --no-gnu-extensions instead of --no_gnu_extensions. Make the
6088 usage message more informative.
6089 Reported by David MacKenzie.
6091 1992-03-09 François Pinard <pinard@iro.umontreal.ca>
6093 * etc/check_examples: New name for check_examples.sh.

6095 * Makefile.in, etc/Makefile.in: Use new names.
6097 * Makefile.in: Transmit $(CC) while making in lib.
6099 * Many *.[hc] files: GNU indent'ed, with further fine tuning of
6100 code disposition by hand.
6102 1992-03-08 François Pinard <pinard@iro.umontreal.ca>
6104 * m4.h: Delete definitions for abort() and exit().
6105 Reported by Richard Stallman.
6107 * config/hmake-unicos, config/s-unicos.h: New files.
6108 Reported by Hal Peterson.
6110 * eval.c (exp_term): Have N^0 return 1.
6111 Reported by Michael Fetterman.
6113 * eval.c, input.c, m4.h: Remove last comma in enums.
6114 Reported by Mike Lijewski.
6116 * Transfer of maintenance duties from René to François.
6118 1991-10-24 René Seindal <seindal@diku.dk>
6120 * Release 1.0. Many thanks to those, who provided me with bug
6121 reports and feedback.
6123 * Uses GNU configure, taken from the gdb distribution.
6125 * Uses GNU getopt(), with long option names.
6127 * The -Q/+quiet option is added, which suppresses warnings about
6128 missing or superflous arguments to built-in macros.
6130 * Added default options via the M4OPTS environment variable.
6132 * The built-in format can now be configured to use sprintf as
6133 the formatting engine, for systems without [efg]cvt(3).
6135 * GNU library code is moved to the ./lib subdirectory; other
6136 utility files are now in ./etc.
6138 * Several minor bugs have been fixed.
6140 1991-07-26 René Seindal <seindal@diku.dk>
6142 * Fixed various bugs. Release 0.99, manual 0.09. Many thanks to
6143 Francois Pinard and Roland H. Pesch for providing me with reports.
6145 * The builtins incr and decr are now implemented without use of
6148 * The builtin indir is added, to allow for indirect macro calls
6149 (allows use of "illegal" macro names).
6151 * The debugging and tracing facilities has been enhanced
6152 considerably. See the manual for details.
6154 * The -tMACRO option is added, marks MACRO for tracing as soon
6157 * Builtins are traced after renaming iff they were before.
6159 * Named files can now be undiverted.
6161 * The -Nnum option can be used to increase the number of
6162 divertions available.
6164 * Calling changecom without arguments now disables all comment
6167 * The function m4_patsubst() is now consistently declared
6170 * A bug in dnl is fixed.
6172 * A bug in the multi-character quoting code is fixed.
6174 * Several typos in the manual has been corrected. More probably
