998 2008-05-05 Eric Blake <ebb9@byu.net>
1000 Stage 22: allow builtin token concatenation outside $@.
1001 Adjust the input and argument parsing engines to append builtins
1002 alongside text. Make define warn when builtins must be
1003 flattened.
1004 Memory impact: slight penalty, with fewer builtins flattened.
1005 Speed impact: slight penalty, from more bookkeeping.
1006 * m4/m4module.h (m4_is_arg_composite): New prototype.
1007 (m4_symbol_value_copy): Change return type.
1008 (m4_arg_text): Add parameter.

1032 Suggested by Mike R.
1034 2008-05-01 Eric Blake <ebb9@byu.net>
1036 Avoid -Wshadow compiler warnings.

1038 * m4/macro.c (make_argv_ref, arg_symbol, m4_arg_symbol)
1039 (m4_is_arg_text, m4_is_arg_func, m4_arg_text, m4_arg_empty)
1040 (m4_arg_len, m4_arg_func, m4__arg_print, m4_make_argv_ref)
1041 (m4_push_arg, m4__push_arg_quote): s/index/arg/.

1109 Reported by Elbert Pol.
1111 2008-04-14 Eric Blake <ebb9@byu.net>
1113 Stage 21b: $@ concatenates builtins, m4wrap takes builtins.
1114 Improve arg_print to handle builtin tokens when printing to a
1115 known chain, rather than always flattening builtins. This allows
1116 m4wrap and $@ back-references to handle embedded builtin tokens.
1117 Memory impact: none.
1118 Speed impact: slight penalty, from more bookkeeping.
1119 * m4/m4module.h (m4_push_builtin): Add parameter.
1120 (m4_builtin_print, m4_push_wrapup_init, m4_push_wrapup_finish)
1121 (m4_arg_print, m4_symbol_value_print): Rename and reduce scope...
1122 * m4/m4private.h (m4__builtin_print, m4__push_wrapup_init)
1123 (m4__push_wrapup_finish, m4__arg_print, m4__symbol_value_print):
1124 ...to these, in some cases adding a parameter.
1125 (m4__append_builtin): New prototype.
1126 * m4/builtin.c (m4_builtin_print): Alter signature to print
1127 builtin to a growing symbol chain.
1128 * m4/symtab.c (m4__symbol_value_print): Alter signature.
1129 (m4_symbol_print, dump_symbol_CB): Adjust callers.
1130 * m4/input.c (builtin_peek, builtin_read, builtin_unget)
1131 (builtin_print, builtin_funcs): Delete, handled via composite
1132 blocks now.
1133 (struct m4_input_block): Delete u.builtin member.
1134 (init_builtin_token): Only use composite block.
1135 (m4__append_builtin): New function.
1136 (m4_push_builtin, m4__push_wrapup_init): Alter signature.
1137 (m4__push_symbol): Allow builtin tokens.
1138 (m4__push_wrapup_finish): Rename.
1139 (composite_print, m4_print_token): Adjust callers.
1140 * m4/macro.c (m4_wrap_args, collect_arguments): Allow builtin
1141 tokens.
1142 (m4__arg_print): Alter signature.
1143 (trace_prepre, trace_pre, m4_arg_text, m4_arg_equal): Adjust
1144 callers.
1145 * modules/m4.c (m4wrap): Allow builtin tokens.
1146 (defn, errprint): Adjust callers.
1147 * modules/gnu.c (builtin): Likewise.
1148 * doc/m4.texinfo (M4wrap): New test.
1149 (Debuglen): Adjust expected output.
1151 Stage 21a: Optimize checks for end of input.
1152 Create a new polymorphic input block type, which always fails with
1153 CHAR_EOF, so that remaining input routines no longer have to check
1154 for NULL input block.
1155 Memory impact: none.
1156 Speed impact: noticeable improvement, from fewer conditionals.
1157 * m4/input.c (eof_funcs, input_eof): New objects.
1158 (eof_peek, eof_read, eof_unget): New functions.
1159 (file_clean, m4_push_string_init, pop_input, m4_push_wrapup_init)
1160 (m4_pop_wrapup, next_char, peek_char, unget_input, m4_input_init)
1161 (m4_input_exit): Use placeholder to guarantee non-NULL isp and
1162 wsp.
1163 (next_char): Rename retry to allow_unget, and change sense for
1164 easier manipulation. All callers changed.
1166 Improve OS/2 detection.
1167 * modules/gnu.c (m4_macro_table): Ensure all possible identifiers
1168 are defined, not just the first. The testsuite ensures that
1169 exactly one gets defined.
1170 * m4/system_.h [__EMX__]: OS/2 is not Unix-compatible, no matter
1171 what other pre-defined macros it has.
1172 * THANKS: Update.
1173 Reported by Elbert Pol.
1175 Ensure __m4_version__ is unquoted.

1188 * tests/others.at (ifndef): New test.
1190 Be namespace clean for M4 version; fixes 2008-04-08 regression.
1191 * configure.ac (version): Rename...
1192 (M4_VERSION): ...to this, since using 'version' broke po.m4.
1194 2008-04-09 Eric Blake <ebb9@byu.net>
1196 Mention 1.4.11 release.
1197 * doc/m4.texinfo (History, Defn, Ifdef, Ifelse, M4wrap)
1198 (Extensions, Improved foreach): Distinguish 1.4.11 and 1.6.
1199 (Format): Add test of C99 hex-float parsing.
1200 * NEWS: Mention 1.4.11 release.
1201 * tests/builtins.at (divert): Add additional test.
1203 2008-04-08 Eric Blake <ebb9@byu.net>
1205 Overhaul inter-version releases to work with git.
1206 * configure.ac (version): New variable, which has nicer version
1207 contents when using git 1.5.5+, hardcoded to 1.9a otherwise.
1208 (TIMESTAMP): Delete, since CVS id expansion died with transition
1209 to git.
1210 (AM_INIT_AUTOMAKE): Use version to decide gnu vs. gnits.
1211 * build-aux/mkstamp: Delete, no longer used.
1212 * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Kill, to speed up
1213 rebuilds when timestamps don't matter.
1214 (MKSTAMP): Delete, no longer used.
1215 (EXTRA_DIST): No longer worry about mkstamp.
1216 (.version): New rule and distributed file.
1217 (doc/m4.1, tests/package.m4): Depend on .version, not
1218 configure.ac, for timestamp.
1219 * ltdl/m4/gnulib-cache.m4: Import git-version-gen module.
1220 * modules/gnu.c (__m4_version__): TIMESTAMP no longer exists.
1221 * src/main.c (main): Likewise.
1223 2008-03-28 Eric Blake <ebb9@byu.net>
1225 Use GNUmakefile module.
1226 * ltdl/m4/gnulib-cache.m4: Import gnumakefile module.
1227 * Makefile.am: Split off maintainer rules...
1228 * maint.mk: ...into this new file.
1230 2008-03-18 Eric Blake <ebb9@byu.net>
1232 Stage 20b: make m4wrap obey POSIX fifo ordering.
1233 Improve input engine to support location changes within symbol
1234 chains, then convert m4wrap to always build symbol chain.
1235 Memory impact: none.
1236 Speed impact: slight penalty, from more m4wrap bookkeeping.
1237 * m4/m4module.h (m4_wrap_args): Add prototype.
1238 * m4/m4private.h (enum m4__symbol_chain_type): Add M4__CHAIN_LOC.
1239 (struct m4__symbol_chain): Add struct u_l.
1240 * m4/input.c (m4_push_wrapup_init, m4_push_wrapup_finish): Use
1241 new link type.
1242 (composite_peek, composite_read, composite_clean): Handle location
1243 link.
1244 * m4/macro.c (m4_wrap_args): New function.
1245 * modules/m4.c (m4wrap): Use it.
1246 * doc/m4.texinfo (M4wrap): Sync with branch and POSIX.
1247 (Extensions): Document extension of multiple arguments.
1248 (Location, Improved m4wrap): Adjust example to match FIFO order.
1249 * tests/builtins.at (wrap): Likewise.
1250 * NEWS: Document this change.
1252 2008-03-17 Eric Blake <ebb9@byu.net>
1254 Stage 20a: reduce unget's in input engine.
1255 Now that out-of-range input placeholders like CHAR_BUILTIN are
1256 consumed outside of next_char, next_token should always consume
1257 rather than peek at the first character. Fewer peeks results in
1258 less ungetc overhead.
1259 Memory impact: none.
1260 Speed impact: noticeable improvement, from fewer function calls.
1261 * m4/input.c (struct input_funcs): Alter read_func prototype.
1262 (next_char, file_read, buildin_read, string_read, composite_read):
1263 Add allow_argv parameter.
1264 (init_builtin_token, init_argv_symbol): Require all prior input to
1265 be consumed.
1266 (m4_skip_line, match_input, consume_syntax): Adjust callers.
1267 (m4__next_token): Consume first byte without peek.
1269 Update for fresh bootstrap.
1270 * ltdl/m4/gnulib-cache.m4: Updated copyright from upstream.
1272 2008-03-15 Eric Blake <ebb9@byu.net>
1274 Document join, in order to fix bug in m4wrap example.
1275 * examples/join.m4: New file.
1276 * examples/wraplifo2.m4: Likewise.
1277 * Makefile.am (EXTRA_DIST): Add new files.
1278 * doc/m4.texinfo (Improved m4wrap): New node.
1279 (Defn, Location): Enhance tests.
1280 (Shift): Document the composite macro join.
1281 (Incompatibilities): Move documentation of LIFO vs. FIFO...
1282 (M4wrap): ...here, to match improved example.
1284 2008-03-13 Eric Blake <ebb9@byu.net>
1286 Stage 19c: allow builtin tokens in more macros.
1287 Allow builtin tokens inside symbol chains, although for now, they
1288 are not allowed inside comments or quotes. Enable builtin token
1289 handling in more macros, if only to consistently diagnose invalid
1290 macro names.
1291 Memory impact: none.
1292 Speed impact: slight impact, due to more bookkeeping.
1293 * m4/m4module.h (m4_symbol_value_lookup, m4_builtin_print): New
1294 prototypes.
1295 * m4/m4private.h (enum m4__symbol_chain_type): Add
1296 M4__CHAIN_FUNC.
1297 (struct m4__symbol_chain): Add builtin member.

1302 (m4__push_symbol): Allow pushing builtin tokens.
1303 (composite_peek, composite_read, composite_unget, composite_clean)
1304 (composite_print): Handle builtin tokens.
1305 (init_builtin_token): Allow builtin tokens from composite input.
1306 (m4__next_token): Flatten builtins inside comment or string.
1307 * m4/macro.c (expand_argument): Strengthen assertion.
1308 (collect_arguments, m4_arg_equal, m4_arg_print, m4_push_args):
1309 Handle builtin tokens.
1310 (arg_symbol): Add parameter, and allow NULL level.
1311 (m4_arg_symbol, m4__push_arg_quote): Adjust callers.
1312 (m4_arg_text): Ensure all builtins have been flattened.
1313 * modules/m4.c (defn, dumpdef, popdef, traceoff, traceon)
1314 (undefine, m4_dump_symbols): Warn on invalid macro names.
1315 (ifdef, ifelse, shift): Handle builtin tokens.
1316 * modules/gnu.c (m4symbols): Likewise.
1317 * doc/m4.texinfo (Defn, Ifdef, Ifelse): Document and test the new
1318 behavior.
1319 (Debuglen): Likewise, and remove xfail.
1320 * NEWS: Mention the change.
1322 Stage 19b: invert sense of bit for handling builtin tokens.
1323 Pass builtin tokens by default, rather than as the exception, so
1324 that the logic can consistently refer to flattening arguments.
1325 Memory impact: none.
1326 Speed impact: none.
1327 * m4/m4module.h (M4BUILTIN_ENTRY): New convenience macro.
1328 (M4_BUILTIN_GROKS_MACRO): Rename...
1329 (M4_BUILTIN_FLATTEN_ARGS): ...and invert sense.
1330 (m4_symbol_value_groks_macro, m4_symbol_groks_macro): Likewise...
1331 (m4_symbol_value_flatten_args, m4_symbol_flatten_args): ...to
1332 this.
1333 * m4/m4private.h (VALUE_MACRO_ARGS_BIT)
1334 (m4_symbol_value_groks_macro): Likewise...
1335 (VALUE_FLATTEN_ARGS_BIT, m4_symbol_value_flatten_args): ...to
1336 this.
1337 * m4/symtab.c (m4_symbol_value_groks_macro): Likewise...
1338 (m4_symbol_value_flatten_args): ...to this.
1339 * m4/macro.c (collect_arguments): Accomodate changed sense.
1340 * m4/module.c (m4__module_open): Require arguments if flattening
1341 is requested.
1342 * m4/input.c (m4_push_string_finish): For now, flatten all
1343 builtins pushed as back-references.
1344 * modules/gnu.c (m4_builtin_table, builtin): Adjust all clients.
1345 * modules/import.c (m4_builtin_table): Likewise.
1346 * modules/load.c (m4_builtin_table): Likewise.
1347 * modules/modtest.c (m4_builtin_table): Likewise.
1348 * modules/mpeval.c (m4_builtin_table): Likewise.
1349 * modules/perl.c (m4_builtin_table): Likewise.
1350 * modules/shadow.c (m4_builtin_table): Likewise.
1351 * modules/stdlib.c (m4_builtin_table): Likewise.
1352 * modules/time.c (m4_builtin_table): Likewise.
1353 * modules/m4.c (m4_builtin_table): Likewise.
1354 (mkstemp): Undo #undef hack from 2006-10-23, now that macro names
1355 are stringized without preprocessor expansion.
1356 * doc/m4.texinfo (Defn): Update comments to match reality.
1357 (Debuglen): Update test now that user macros pass builtin tokens.
1359 Stage 19a: sort and cache builtins loaded by a module.
1360 Rather than repeatedly using dlsym to browse the builtin table,
1361 copy off the table at module load time. Then, the input engine
1362 merely refers to the copy instead of duplicating information.
1363 Memory impact: slight penalty, due to more memory per module, but
1364 offset by less memory in input engine.
1365 Speed impact: slight improvement, due to faster builtin lookups.
1366 * m4/m4module.h (m4_set_symbol_value_builtin): Delete. Use
1367 m4_builtin_find_by_* instead.
1368 (m4_builtin_find_by_func): Change return type.
1369 * m4/m4private.h (m4__builtin): New struct.

1374 new field type.
1375 * m4/symtab.c (m4_set_symbol_value_builtin): Rename...
1376 (m4__set_symbol_value_builtin): ...and populate additional fields,
1377 based on new type.
1378 (m4_get_symbol_value_func, m4_get_symbol_value_builtin): Adjust to
1379 new field type.
1380 * m4/module.c (install_builtin_table): Use cached table.
1381 (compare_builtin_CB): New helper function.
1382 (m4__module_open): Populate table.
1383 (module_remove): Free table.
1384 * m4/builtin.c (compare_builtin_name_CB): New helper function.
1385 (m4_builtin_find_by_name): Rewrite to use sorted table.
1386 (m4_builtin_find_by_func): Change return type.
1387 * m4/input.c (struct m4_input_block): Simplify u_b, since most
1388 fields can be determined from builtin.
1389 (builtin_peek, builtin_read, builtin_unget, init_builtin_token)
1390 (m4__next_token): Alter parsing so that only init_builtin_token
1391 consumes a builtin.
1392 (builtin_print, m4_push_builtin): Adjust all users.

1427 * NEWS: Update from branch.
1429 2008-02-23 Eric Blake <ebb9@byu.net>
1431 Stage 18: try harder to reuse argv in recursion.
1432 When pushing arguments that contain an existing $@ ref, reuse the
1433 ref rather than creating another layer of wrappers.
1434 Memory impact: noticeable improvement, due to better $@ reuse.
1435 Speed impact: noticeable improvement, due to O(n^2) to O(n)
1436 reduction in unboxed recursion.
1437 * m4/macro.c (make_argv_ref): Avoid wrapping $@ when possible.
1438 (m4_push_args): Let make_argv_ref take care of pending data.
1439 * doc/m4.texinfo (Improved foreach): Tweak wording to match new
1440 performance capability.
1441 * tests/others.at (recursion): Add tests to avoid performance
1442 regression.
1444 2008-02-22 Eric Blake <ebb9@byu.net>
1446 Update NEWS.
1447 * NEWS: Document change to __gnu__ on 2008-02-11.
1449 Stage 17: pass argv through quoted strings.
1450 Allow the concatenation of $@ references with other text input
1451 inside quoted contexts, which requires distinguishing between a
1452 wrapper around many arguments vs. a reference serving as part of a
1453 single argument. Also optimize based on whether argv contains
1454 builtin tokens that might need flattening to the empty string.
1455 Memory impact: noticeable improvement, due to O(n^2) to O(n)
1456 reduction from total reuse of $@ references.
1457 Speed impact: noticeable improvement, due to O(n^2) to O(n)
1458 reduction in boxed recursion.
1459 * m4/m4module.h (m4_arg_equal, m4_arg_len): Add parameter.
1460 (M4ARGLEN): Adjust definition.
1461 * m4/m4private.h (struct m4__symbol_chain): Add has_func member.
1462 (struct m4_symbol_value): Add wrapper and has_func members.
1463 (struct m4_macro_args): Add flatten and has_func members.
1464 * m4/input.c (append_quote_token): Return argv refs inside quoted
1465 strings.
1466 (init_argv_symbol): Populate new fields.
1467 * m4/macro.c (expand_argument, collect_arguments, make_argv_ref)
1468 (m4_make_argv_ref): Likewise.

1472 new parameter.
1473 * modules/m4.c (ifelse): Adjust caller.
1475 2008-02-22 Gary V. Vaughan <gary@gnu.org>
1477 Fix regression in argument collection, from 2008-01-21.
1478 * m4/input.c (m4__next_token): When DEBUG_INPUT is defined,
1479 undo argument collection optimisation for strings, so that
1480 m4_print_token doesn't abort when it otherwise receives an
1481 unprintable M4_SYMBOL_VOID type token.
1483 2008-02-20 Eric Blake <ebb9@byu.net>
1485 Stage 16: cache quotes and improve m4_arg_print.
1486 Cache rather than always copying quotes when pushing $@ refs; in
1487 particular, reconstruct single-byte quotes on the fly. Allow NUL
1488 through m4wrap. Improve sharing of code that prints arguments.
1489 Memory impact: slight improvement, due to cached quotes.
1490 Speed impact: slight improvement, due to less copying.
1491 * m4/m4module.h (m4_symbol_value_print, m4_symbol_print)
1492 (m4_arg_print): Adjust prototypes.
1493 (m4_dump_args): Delete.
1494 (m4_push_wrapup): Split...

1496 prototypes.

1504 (m4_symbol_print, dump_symbol_CB): Adjust all callers.
1505 * m4/utility.c (m4_dump_args): Delete; callers should use
1506 m4_arg_print instead.
1507 * m4/input.c (m4_push_wrapup_init, m4_push_wrapup_finish): Split
1508 implementation, and allow embedded NUL.

1510 (composite_read, append_quote_token): Adjust all callers.
1511 * m4/macro.c (trace_prepre, m4_arg_text, make_argv_ref):
1512 Likewise.

1559 * doc/m4.texinfo (Improved forloop): Document advantage of $0.
1560 (Improved foreach): Adjust dump from file.
1562 Stage 15: return argv refs back to collect_arguments.
1563 Collect an entire $@ reference at once rather than one argument at
1564 a time, outside of quotes (but inside quotes, $@ is still
1565 flattened for now). The skip_last field allows concatenation of
1566 $@ with other text when collecting arguments.
1567 Memory impact: noticeable improvement, due to better reuse of $@.
1568 Speed impact: noticeable improvement, due to less parsing.
1569 * m4/m4private.h (CHAR_ARGV): New input engine sentinel.
1570 (enum m4__token_type): Add M4_TOKEN_ARGV.
1571 (struct m4__symbol_chain): Add skip_last member to argv link.

1669 Stage 14b: allow pushing argv references.
1670 Push a $@ reference to the input engine in one go, rather than
1671 pushing each element. For now, argument collection still gets one
1672 argument of a $@ at a time; but the penalties of this patch make
1673 it easier to manage $@ efficiently in future patches.
1674 Memory impact: noticeable penalty, due to larger struct and O(n)
1675 to O(n^2) on unboxed recursion.
1676 Speed impact: noticeable penalty, due to more bookkeeping.

1690 (m4_push_args): Adjust caller.
1691 * m4/symtab.c (m4_symbol_value_print): Likewise.
1693 Stage 14a: allow printing argv references.

1701 (file_peek, builtin_peek, string_peek): Ignore new parameter.
1702 (composite_peek): Ignore new parameter, for now.
1703 (composite_clean, pop_input): Rework to minimize indirection, and
1704 to avoid infinite recursion in next patch.
1705 * m4/macro.c (trace_prepre, trace_pre): Adjust callers.
1706 (m4_arg_print): New function.
1707 * m4/symtab.c (m4_symbol_value_print): Update signature.

1759 Stage 13: push composite text tokens.
1760 Support pushing composite tokens, allowing back-references to be
1761 reused through multiple macro expansions. Add hueristic that
1762 avoids creating new reference when pushing existing references.
1763 Memory impact: noticeable improvement due to better reference
1764 reuse, except for O(n) to O(n^2) copying in boxed recursion.
1765 Speed impact: slight penalty, due to more bookkeeping.
1766 * m4/m4private.h (m4__push_symbol): Adjust prototype.

1816 * modules/m4.c (dumpdef, m4_make_temp): Likewise.
1817 * src/freeze.c (produce_frozen_state): Likewise.
1818 * tests/freeze.at (reloading unknown builtin): Update test.
1820 Stage 12a: make m4_symbol_chain a union.
1821 Shrink size of symbol chains by using a union.
1822 Memory impact: slight improvement, due to smaller struct.
1823 Speed impact: slight improvement, due to less bookkeeping.
1824 * m4/m4private.h (enum m4__symbol_chain_type): New enum.
1825 (struct m4_symbol_chain): Rename...
1826 (struct m4__symbol_chain): ...to this, since it is internal.
1827 * m4/symtab.c (m4_symbol_value_copy, m4_symbol_value_print): All
1828 callers updated.
1829 * m4/input.c (struct m4_input_block, m4__push_symbol)
1830 (composite_peek, composite_read, composite_unget)
1831 (composite_clean, composite_print, m4__make_text_link)
1832 (append_quote_token): Likewise.
1833 * m4/macro.c (expand_macro, arg_mark, m4_arg_symbol, m4_arg_text)
1834 (m4_arg_equal, m4_arg_len, m4_make_argv_ref, m4_push_arg)
1835 (m4_push_args): Likewise.
1837 2008-01-23 Eric Blake <ebb9@byu.net>
1839 Adjust to recent libtool interface change.
1840 * configure.ac (LT_PREREQ): Require bleeding-edge libtool.
1841 (LT_WITH_LTDL): Delete, now that it is obsolete.
1842 (LTDL_INIT): Use new libtool macro.
1844 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1845 and Eric Blake <ebb9@byu.net>
1847 Rely on newer automake.
1848 * configure.ac (AM_INIT_AUTOMAKE): Require 1.10.1, and add lzma
1849 distribution.
1850 * bootstrap: Update automake requirement.
1851 (func_version): Fix --version output, broken since 2007-08-06.
1852 * HACKING: Likewise. Add lzma requirement.
1853 * Makefile.am (clean-local-src): Not needed any more with newest
1854 Automake.
1855 (clean-local): Adjust.
1856 * TODO: Remove completed item.
1858 2008-01-22 Eric Blake <ebb9@byu.net>
1860 Doc tweak.
1861 * doc/m4.texinfo (Renamesyms): Avoid underfull hbox, and improve
1862 example.
1864 2008-01-21 Eric Blake <ebb9@byu.net>
1866 Stage 11: full circle for single argument references.
1867 Pass quoted strings through to argument collection in a single
1868 action, so that an argument can be reused throughout macro
1869 recursion if it remains unchanged.
1870 Memory impact: noticeable improvement, due to more reuse in
1871 argument collection stacks; O(n^2) to O(n) on boxed recursion.
1872 Speed impact: noticeable improvement, due to less copying.
1873 * m4/m4module.h (m4_arg_text): Add parameter.
1874 (M4ARG): Adjust.
1875 * m4/m4private.h (CHAR_QUOTE): New input engine sentinel.
1876 (m4__make_text_link): New prototype.
1877 (struct m4_symbol_chain): Add quote_age member.
1878 (struct m4_symbol_value): Add end member to chained symbol.
1879 (struct m4_macro_args): Add wrapper member.
1880 * m4/symtab.c (m4_symbol_value_print): Print composite tokens.
1881 (m4_symbol_value_copy, m4_symbol_value_delete): Recognize
1882 composite tokens.
1883 * m4/input.c (make_text_link): Rename...
1884 (m4__make_text_link): ...to this, and export.
1885 (m4_push_string_finish): Adjust caller.
1886 (make_text_link, m4__push_symbol): Update new field.
1887 (file_read, builtin_read, string_read, composite_read, next_char):
1888 Add parameter.
1889 (m4_skip_line, match_input, consume_syntax): Adjust callers.
1890 (append_quote_token): New function.
1891 (m4__next_token): Pass quoted strings onto argument collection.
1892 (m4_print_token) [DEBUG_INPUT]: Update.
1893 * m4/macro.c (expand_argument): Collect composite arguments.
1894 (collect_arguments): Update new field.
1895 (expand_macro): Reduce ref-count of back-references after use.
1896 (arg_mark, m4_arg_symbol, m4_make_argv_ref): Adjust to new member
1897 names.
1898 (m4_is_arg_text): Also recognize composite symbols as text.
1899 (m4_arg_text, m4_arg_len): Merge composite symbols as needed.
1900 (m4_arg_equal): Compare composite symbols.
1901 (m4_push_arg, m4_push_args): Handle composite symbols.
1902 (m4_arg_symbol): Relax assertion.
1903 (process_macro): Use single-argument references.
1904 * m4/output.c (m4_shipout_string_trunc): Update comment.
1905 * tests/macros.at (Rescanning macros): Augment test.
1907 2008-01-16 Eric Blake <ebb9@byu.net>
1909 Stage 10: avoid extra copying of strings and comments.
1910 When collecting tokens that are immune to further expansion, avoid
1911 copying data from one obstack to another by outputting it into the
1912 destination obstack to begin with. Also reduce copying done in
1913 format builtin.
1914 Memory impact: slight improvement, due to better obstack usage.
1915 Speed impact: noticeable improvement, due less data copying.
1916 * ltdl/m4/gnulib-cache.m4: Import intprops and vasnprintf-posix
1917 modules.
1918 * m4/m4private.h (m4__token_type): Adjust prototype.
1919 * m4/input.c (m4__next_token): Support new parameter.
1920 * m4/macro.c (m4_macro_expand_input, expand_token)
1921 (expand_argument, collect_arguments): Adjust callers.
1922 * modules/m4.c (ntoa): Tighten buffer size.
1923 * m4/output.c (m4_tmpname): Guarantee no buffer overflow.
1924 * modules/format.c (arg_int, arg_long, arg_double): New helper
1925 functions, to detect overflow or unparsed characters.
1926 (ARG_INT, ARG_LONG, ARG_STR, ARG_DOUBLE): Adjust to check for
1927 missing or excess arguments.
1928 (format): Likewise, and also output directly into obstack if there
1929 is room.
1930 * doc/m4.texinfo (History): Update for new year.
1931 (Format): Test for new warnings.
1933 2008-01-15 Eric Blake <ebb9@byu.net>
1935 * TODO: Update with some newer URLs.
1937 Verify linear `index'.
1938 * tests/builtins.at (index): New test.
1939 (translit): Make test take longer, to make quadratic algorithms
1940 more apparent.
1942 2007-12-20 Eric Blake <ebb9@byu.net>
1944 Stage 9: share rather than copy single-arg refs.
1945 Use hooks of previous patch to create back-references to arguments
1946 in the input engine, and inline short text rather than always
1947 creating a FIFO link. Also start testing embedded NUL behavior.
1948 Until the argument collection engine also shares references, the
1949 memory usage increases.
1950 Memory impact: noticeable penalty, due to longer life of argv
1951 changing O(n) to O(n^2) on boxed recursion.
1952 Speed impact: slight improvement, due less data copying.
1953 * ltdl/m4/gnulib-cache.m4: Import memmem and quote modules.
1954 * m4/m4module.h (m4_arg_scratch): New prototype.
1955 * m4/m4private.h (m4__push_symbol): Add parameter.
1956 (m4_arg_scratch): Add fast accessor.
1957 (struct m4): Add expansion_level member, taken...
1958 * m4/macro.c (expansion_level): ...from here. Adjust all users.
1959 (expand_argument): Minor cleanup.
1960 (expand_macro): Track scratch space per macro call.
1961 (m4_arg_scratch): New function.
1962 (m4_make_argv_ref): Call new function.
1963 (m4_push_arg): Push reference to $0.
1964 (m4_push_args): Rework separator usage, since separators will
1965 usually be inlined.
1966 (process_macro): Allow embedded NUL.
1967 * m4/input.c (INPUT_INLINE_THRESHOLD): New define.
1968 (m4__push_symbol): Add parameter. Inline short strings, and save
1969 references through rescanning.
1970 * m4/symtab.c (m4_set_symbol_value_text): Weaken assertion.
1971 * modules/m4.c (errprint, index): Handle NUL transparently.
1972 (dumpdef, translit): Use scratch space, rather than expansion
1973 stack.
1974 * modules/gnu.c (renamesyms, m4symbols): Likewise.
1975 * tests/others.at (nul character): New test.
1976 (iso8859): Quote absolute file name, remove XFAIL.
1977 * tests/iso8859.m4: Avoid raw NUL in output.
1978 * tests/null.m4: New file.
1979 * tests/null.out: Likewise.
1980 * tests/null.err: Likewise.
1981 * Makefile.am (OTHER_FILES): Distribute new files.
1982 * .gitattributes: Treat new files as text.
1984 2007-12-17 Eric Blake <ebb9@byu.net>
1986 Stage 8: extend life of references into argv.
1987 Add hooks to lengthen the lifetime of arguments reused in a macro
1988 expansion, rather than always discarding arguments at the end of
1989 expand_macro. Rework the expand_macro obstacks to handle longer
1990 lifetimes. For now, the hooks remain unused.
1991 Memory impact: slight penalty, due to larger structs.
1992 Speed impact: slight penalty, due to more bookkeeping.
1993 * m4/system_.h (obstack_regrow): Delete.
1994 * m4/m4private.h (struct m4_symbol_chain): Add level field.
1995 (m4__push_symbol): Adjust prototype.
1996 (m4__adjust_refcount): New prototype.
1997 (DEBUG_MACRO) [DEBUG]: New debug control.
1998 (struct m4__macro_arg_stacks): New structure.
1999 (struct m4): Add arg_stacks, stacks_count fields.
2000 * m4/m4module.h (m4_make_argv_ref): Add parameter.
2001 * m4/macro.c (argc_stack, argv_stack): Delete, replaced by
2002 context->arg_stacks.
2003 (m4_macro_expand_input) [DEBUG_MACRO]: Add debug hooks,
2004 conditional on M4_DEBUG_MACRO envvar.
2005 (collect_arguments): Adjust signature.
2006 (expand_macro): Rework obstack handling.
2007 (m4__adjust_refcount, arg_mark): New functions.
2008 (m4_make_argv_ref): Populate new field.
2009 (m4_push_arg, m4_push_args): Track inuse.
2010 (process_macro): One less cast.
2011 * m4/m4.c (m4_delete): Clean up arg_stacks.
2012 * m4/input.c (make_text_link): Use new field.
2013 (m4__push_symbol, file_clean): Update signature.
2014 (composite_read): Bump refcount when done with reference.
2015 (composite_clean): New function.
2016 (pop_input): Adjust caller.
2017 * m4/debug.c (m4_debug_message): Make assertion match comment.
2018 * modules/gnu.c (builtin, indir): Adjust callers.
2019 * tests/builtins.at (ifelse): New test.
2020 (exp): Move and rename...
2021 * tests/others.at (countdown): ...to this.
2022 * doc/m4.texinfo (Improved foreach): Fix tracing usage in
2023 example.
2025 2007-12-13 Eric Blake <ebb9@byu.net>
2027 Yet more rewording.
2028 * doc/m4.texinfo (Inhibiting Invocation): Missed one instance in
2029 the previous patch.
2031 * THANKS: Update.
2033 2007-12-13 Paolo Bonzini <bonzini@gnu.org> (tiny change)
2035 * doc/m4.texinfo (Inhibiting Invocation): Fix quoting of a quoting
2036 example.
2037 Reported by Giovanni Toffetti.
2039 2007-12-11 Eric Blake <ebb9@byu.net>
2041 Stage 7: use chained input support in input parser.
2042 Allow the LIFO input engine to rescan a macro expansion composed
2043 of smaller chunks of FIFO data, rather than the old approach of a
2044 monolithic string. For now, all chunks are still copied.
2045 Memory impact: slight penalty, due to FIFO chain overhead.
2046 Speed impact: slight penalty, due to extra bookkeeping.
2047 * m4/m4private.h (m4__push_symbol): New prototype.
2048 (struct m4_symbol_chain): Add const-safety.
2049 * m4/symtab.c (m4_symbol_value_print): Simplify.
2050 (dump_symbol_CB): Update caller.
2051 * m4/input.c (struct m4_input_block): Alter u_c member, first
2052 introduced 2006-10-25, but unused until now.
2053 (composite_peek, composite_read, composite_unget)
2054 (composite_print, init_builtin_token): Rewrite accordingly.
2055 (m4_push_wrapup): No longer need trailing NUL.
2056 (m4__push_symbol, make_text_link): New functions.
2057 (m4_push_string_finish): Use them.
2058 * m4/macro.c (m4_push_arg, m4_push_args): Likewise.
2059 (expand_macro): Simplify logic of nesting_limit.
2060 * src/main.c (main): Likewise.
2061 * doc/m4.texinfo (Dumpdef): Augment test.
2063 2007-12-08 Eric Blake <ebb9@byu.net>
2065 Stage 6: convert builtins to push arg at a time.
2066 Add new methods to factor all builtins whose expansion includes an
2067 argument, making back-reference creation easier in future patches.
2068 Factor out length-limited printing to obstacks, and use -1 rather
2069 than 0 for unlimited length.
2070 Memory impact: none.
2071 Speed impact: slight improvement, due to better code sharing.
2072 * m4/m4module.h (m4_shipout_text): Rename...
2073 (m4_divert_text): ...to this, to avoid confusion with m4_shipout_*
2074 that does not worry about sync lines.
2075 (m4_shipout_string_trunc): New prototype.
2076 * m4/output.c (m4_shipout_text): Rename...
2077 (m4_divert_text): ...to this.
2078 (m4_shipout_string): Move guts...
2079 (m4_shipout_string_trunc): ...to this new function.
2080 * m4/macro.c (m4_push_arg, m4_push_args): New functions.
2081 (expand_token, process_macro): Update callers.
2082 * m4/input.c (string_print): Likewise.
2083 * modules/m4.c (ifdef, ifelse, shift, substr, translit, divert):
2084 Likewise.
2085 * modules/gnu.c (patsubst): Likewise.
2086 (debuglen): Use SIZE_MAX for unlimited debug length.
2087 * src/main.c (main): Likewise.
2088 * m4/m4.c (m4_create): Default max_debug_length to SIZE_MAX, not
2089 zero.
2091 2007-12-07 Eric Blake <ebb9@byu.net>
2093 Minor security fix: Quote output of mkstemp.
2094 * modules/m4.c (m4_make_temp): Produce quoted output.
2095 * doc/m4.texinfo (Mkstemp, Mkdtemp): Update the documentation and
2096 tests.
2098 Stage 5: add notion of quote age.
2099 Cache the quoting rules that were in effect when a string was
2100 parsed, to avoid reparsing that string if no changequote or other
2101 quote age change took place in the meantime. A quote_age of 0 is
2102 always safe, but does not benefit from caching.
2103 Memory impact: slight improvement, due to smaller struct in input
2104 engine.
2105 Speed impact: slight penalty, due to more bookkeeping.
2106 * m4/m4module.h (m4_get_symbol_value_quote_age): New prototype.
2107 (m4_set_symbol_value_text): Adjust prototype.
2108 (m4_has_syntax): Factor out the unsigned char cast.
2109 * m4/m4private.h (struct m4_syntax_table): Add syntax_age and
2110 quote_age members.
2111 (m4__quote_age, m4__safe_quotes): New accessor macros, no need for
2112 functions at this point.
2113 (struct m4_symbol_value, struct m4_macro_args): Add quote_age
2114 member.
2115 (m4_set_symbol_value_text): Adjust fast accessor.
2116 (m4_get_symbol_value_quote_age): New fast accessor.
2117 * m4/symtab.c (m4_set_symbol_value_text): Add parameter.
2118 (m4_get_symbol_value_quote_age): New function.
2119 (m4_symbol_value_copy): Adjust callers.
2120 * m4/macro.c (expand_token): Add parameter, and track quote age.
2121 (expand_argument, collect_arguments): Track quote age.
2122 (m4_macro_expand_input, process_macro, m4_make_argv_ref)
2123 (m4_macro_expand_input): Update callers.
2124 (m4_arg_text, m4_arg_len, m4_arg_func): Abort on type mismatch.
2125 * m4/input.c: Comment cleanups.
2126 (struct m4_input_block): Reduce size.
2127 (m4__next_token): Report quote age.
2128 (m4_push_builtin, init_builtin_token): Update callers.
2129 * m4/utility.c (skip_space): Adjust callers.
2130 * m4/module.c (install_macro_table): Likewise.
2131 * m4/syntax.c (m4_set_syntax): Initialize and update quote age.
2132 (m4_set_quotes, m4_set_comment): Detect no-op changes, and update
2133 quote age.
2134 (set_quote_age): New helper function.
2135 (check_is_single_quotes, check_is_single_comments): Adjust
2136 callers.
2137 * src/freeze.c (reload_frozen_state): Likewise.
2138 * src/main.c (main): Likewise.
2139 * modules/m4.c (define, pushdef): No need to set macro text.
2140 * tests/builtins.at (changequote, defn): New tests.
2141 * examples/wrapfifo.m4: New file.
2142 * examples/wraplifo.m4: New file.
2143 * Makefile.am (dist_pkgdata_DATA): Distribute new examples.
2145 2007-12-04 Eric Blake <ebb9@byu.net>
2147 Fix builds with OpenBSD make.
2148 * Makefile.am (HELP2MAN): New macro.
2149 (dist_man_MANS, doc/m4.1): Fix rules for building m4.1 into
2150 srcdir.
2151 * README: Update copyright.
2152 * HACKING: Mention help2man and makeinfo dependencies.
2154 2007-11-29 Eric Blake <ebb9@byu.net>
2156 Stage 4: route indir, builtin through ref; make argv opaque.
2157 Finish making struct opaque to all but the input engine, by
2158 reworking obstack usage in expand_macro to better support creation
2159 of a $@ reference. Canonicalize the empty argument, to allow
2160 pointer comparison optimizations.
2161 Memory impact: slight penalty, due to larger struct.
2162 Speed impact: slight improvement, due to fewer function calls.
2163 * m4/system_.h (obstack_regrow): Fix precedence.
2164 * m4/m4module.h (m4_arg_equal, m4_arg_empty, m4_make_argv_ref):
2165 New prototypes.
2166 (struct m4_macro_args): Move...
2167 * m4/m4private.h (struct m4_macro_args): ...here, making it opaque
2168 to modules. Add has_ref member.
2169 (bool_bitfield): New helper typedef.
2170 (struct m4_symbol_chain): Add flatten and len members.
2171 * m4/macro.c (empty_symbol): New placeholder, for optimizing
2172 comparison with empty string.
2173 (m4_macro_expand_input): Initialize it.
2174 (collect_arguments): Alter signature, and populate new fields.
2175 (trace_pre, trace_post): Remove redundant parameter.
2176 (expand_macro): Alter handling of obstacks.
2177 (m4_arg_symbol): Account for wrapped argv.
2178 (m4_arg_equal, m4_arg_empty, m4_make_argv_ref): New methods.
2179 (m4_arg_text, m4_arg_len, m4_arg_func): Use new methods.
2180 * modules/m4.c (ifelse, syscmd): Likewise.
2181 * modules/evalparse.c (m4_evaluate): Likewise.
2182 (undefine, popdef, m4_dump_symbols): Optimize.
2183 * modules/gnu.c (builtin, indir, esyscmd, debugfile): Use new
2184 methods.
2185 (changesyntax, regexp): Optimize.
2186 * m4/output.c (diversion_storage): Use typedef.
2188 Stage 3b: cache length, rather than computing it, in modules.
2189 Use cached token length in builtins and output engine.
2190 Memory impact: none.
2191 Speed impact: noticeable improvement, due to fewer function calls.
2192 * m4/hash.c (m4_hash_remove): Avoid double free on remove
2193 failure.
2194 * m4/output.c (m4_shipout_string): Change semantics of len param.
2195 (m4_shipout_int): Use cached length.
2196 * m4/input.c (m4_push_string_finish): Likewise.
2197 * modules/m4.h (m4_make_temp_func): Add parameter.
2198 * m4/macro.c (expand_token, m4_arg_len): Use cached length.
2199 (collect_arguments, expand_macro): Alter signature.
2200 (trace_format): Don't use out-of-scope buffer.
2201 (process_macro): All callers changed.
2202 * m4/utility.c (m4_dump_args): Likewise.
2203 * m4/symtab.c (m4_symbol_value_print): Likewise.
2204 * modules/gnu.c (__file__, __program__, builtin, indir)
2205 (m4symbols, mkdtemp, regexp_compile, regexp_substitute,
2206 renamesyms, patsubst, regexp, regexp_compile): Likewise.
2207 * modules/load.c (m4modules): Likewise.
2208 * modules/m4.c (defn, m4wrap, maketemp, m4_make_temp)
2209 (numb_obstack, ifdef, ifelse, divert, len, substr): Likewise.
2210 * modules/perl.c (perleval): Likewise.

2214 * src/freeze.c (dump_symbol_CB): Likewise.
2215 * doc/m4.texinfo (Renamesyms, Dumpdef, Changesyntax): Adjust test.
2216 * tests/builtins.at (mkstemp): Likewise.
2217 * tests/others.at (iso8859): XFAIL this test, now that
2218 length-based handling allows NUL through part but not all of M4.
2220 2007-11-28 Eric Blake <ebb9@byu.net>
2222 Stage 3a: cache length, rather than computing it, in libm4.
2223 Cache the length of a token in the input engine and symbol table,
2224 to avoid repeating lots of strlen calls. Additionally, by using
2225 obstack length rather than strlen, the input engine can now
2226 support embedded NUL.
2227 Memory impact: slight penalty, due to larger struct.
2228 Speed impact: slight improvement, due to fewer function calls.
2229 * m4/m4module.h (struct m4_macro_args): Cache length.
2230 (m4_get_symbol_len, m4_get_symbol_value_len): New accessors.
2231 (m4_set_symbol_value_text): Change signature.
2232 * m4/m4private.h (struct m4_symbol_value): Store string length.

2254 2007-11-27 Eric Blake <ebb9@byu.net>
2256 Stage 2: use accessors, not direct reference, into argv.
2257 Outside of macro.c, use accessor methods rather than direct access
2258 into the argv struct.

2359 Handle some defn corner cases differently.
2360 * doc/m4.texinfo (Defn): Update documentation; although this still
2361 doesn't match the branch, since it may be changed before 2.0.
2362 * m4/macro.c (expand_argument): Consistently ignore builtins in
2363 concatenation contexts.
2364 * m4/m4private.h (m4__symbol_type): Fix C89 compliance bug.

2368 Note: Patches titled Stage 0 through N form a series of patches
2369 which decreases the algorithmic complexity of tail recursion in

2663 (func_get_translations): The first awk script mangles the last
2664 entry passed to it for at least the awk implementation shipped

2666 around that problem.
2668 2007-08-29 Gary V. Vaughan <gary@gnu.org>
2670 As gnulib xstrtol is only used by main, and unconditionally pulls
2671 in a copy of getopt, undo bootstrap change from 2007-08-11 below,

2673 without pushing the extra code into libm4:
2675 * bootstrap (src_modules): Add getopt and xstrtol modules.
2676 * Makefile.am (src_m4_SOURCES): Add xstrtol sources.
2677 * po/POTFILES.in: Move gnu/xstrtol-error.c to src/xstrtol-error.c.

3070 M4 was designed to have a small number of header files defining
3071 the interfaces to several source files each. Keeping this in
3072 mind allows us to tidy things up considerably. Having done this,
3073 it becomes clear that some of the installed headers reference
3074 other headers which are not installed (but that's another patch):

5123 The regs_allocated field in a struct re_pattern_buffer refers
5124 to the state of a particular re_registers struct when used in
5125 successive matches using the same compiled pattern. Avoid a

5158 * Makefile.am (src_m4_DEPENDENCIES): Make dependency explicit.
5159 (clean-local): Split into and depend upon...
5160 (clean-local-tests, clean-local-src): ...these two. The latter
5161 removes the libtool object directory below `src', to work around
5162 a buglet in Automake, failing to list it.
5163 (EXTRA_DIST): Distribute modules/perl.c.
5165 2006-06-19 Eric Blake <ebb9@byu.net>
5167 * Makefile.am ($(srcdir)/doc/m4.1): No need to list $(srcdir) in
5168 right side of dependency; VPATH does that.

5170 (EXTRA_DIST): Distribute stamp-vcl.
5171 Reported by Ralf Wildenhues.
5172 (TESTSUITE): Revert earlier change that used absolute path, as
5173 that broke 'make dist' in VPATH. Stick with $(srcdir) instead.
5174 (EXTRA_DIST): Revert earlier change of $(TESTSUITE).
5175 (TESTS_ENVIRONMENT) [USE_GMP]: Revert earlier addition, since
5176 atlocal takes care of it instead.
5177 (check-local, installcheck-local, clean-local): Inline absolute
5178 path to testsuite here, rather than relative path to testsuite
5179 elsewhere.
5181 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5183 * m4/m4private.h (DELETE): Cast away const here...
5184 * src/stackovf.c (stackovf_exit): ...to avoid cast-as-lvalue here.
5185 * src/freeze.c (reload_frozen_state): Avoid uninitialized
5186 variable warning.
5188 2006-06-19 Eric Blake <ebb9@byu.net>

5193 (EXTRA_DIST): Inline definition of testsuite, so that make dist
5194 works again.
5196 2006-06-16 Eric Blake <ebb9@byu.net>
5198 Follow recommendations from autoconf manual for autotest.
5199 * Makefile.am (TESTSUITE): Factor the $(srcdir) out of uses, and
5200 turn it into an absolute path until autotest provides an option
5201 that allows us to avoid changing directories. Properly quote
5202 throughout.
5203 (TESTS_ENVIRONMENT) [USE_GMP]: Inform testsuite about GMP.
5204 (check-recursive): Delete unused target.
5205 ($(TESTSUITE)): Atomically update testsuite.
5206 (CD_TESTDIR): Simplify.
5207 (m4__cd): Delete unused macro.

5212 (DISTCLEANFILES, MAINTAINERCLEANFILES): Add directory location.
5213 * README: Document how to use the testsuite.
5215 2006-06-15 Eric Blake <ebb9@byu.net>

5231 conditional.
5232 * ltdl/m4/m4-gnulib.m4: Delete, no longer needed.
5234 Reduce compiler warnings. Inside GMP, mpq_t is an array type, so
5235 const mpq_t is not assignable from plain mpq_t. Avoid
5236 type-punning warnings caused trying to mix these types.
5237 * modules/mpeval.c (numb_ior, numb_eor, numb_and, numb_lshift),
5238 (numb_rshift, numb_divide, numb_modulo): Remove const qualifier.

5240 (mult_term, exp_term): Remove type-punning casts.
5241 (numb_pow): Remove const qualifier.
5242 * src/freeze.c (reload_frozen_state): Fix typo in messages.
5243 Fix variables that can be used uninitialized, which fixes
5244 security hole where malicious frozen file can execute arbitrary
5245 code.

5260 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5262 * Makefile.am (AM_CPPFLAGS): Add $(LTDLINCL), so the right
5263 ltdl.h is used.
5265 * bootstrap: Do not run libtoolize manually, this is done
5266 correctly by autoreconf. Invoke autoreconf with --no-recursive
5267 to avoid unnecessary rerunning of autotools for libltdl.
5269 2006-06-13 Eric Blake <ebb9@byu.net>
5271 * THANKS: Update.
5273 2006-06-12 Eric Blake <ebb9@byu.net>
5275 * m4/output.c [HAVE_MKTEMP]: Gnulib provides mkstemp, so don't
5276 bother with mktemp.
5277 * src/m4.h: Don't declare mktemp.
5278 * m4/input.c (m4__next_token): Avoid bzero.
5279 * configure.ac (AC_CHECK_FUNCS): Remove obsolete checks.
5280 * Makefile.am (doc/m4.1): Depend on installed help2man, rather
5281 than distributing outdated helptoman.pl.
5282 * doc/helptoman.pl: Delete.
5284 2006-06-10 Eric Blake <ebb9@byu.net>
5286 * README (Patches): Document the current dependence on CVS
5287 builds of autotools.

5295 (AC_PROG_AWK, AM_C_PROTOTYPES, AC_C_CONST, AC_HEADER_STDC),
5296 (AC_CHECK_HEADERS, AC_FUNC_ALLOCA, AC_FUNC_VPRINTF): Remove checks
5297 done by gnulib or automake, or which autoconf has declared
5298 obsolete.

5311 * BACKLOG: Delete. This file is too old and unmaintained to be
5312 worthwhile.
5313 * ChangeLog: Change encoding to UTF-8.
5315 Avoid compiler warnings.
5316 * m4/macro.c (trace_format): Don't mark this as a printf format,
5317 since we don't accept the same set of modifiers as printf. It
5318 would be nice if gcc let us specify a custom format archetype.
5319 * src/main.c (main): Cast away const.
5321 2006-06-10 Andreas Schwab <schwab@suse.de> (tiny change)

5339 2006-05-06 Eric Blake <ebb9@byu.net>
5341 * po/Makevars (MSGID_BUGS_ADDRESS): Add.
5342 * po/POTFILES.in (src/getopt.c, src/version-etc.c): These files live
5343 in src, not gnu.
5345 2006-05-06 Eric Blake <ebb9@byu.net>
5347 * configure.ac (LT_CONFIG_LTDL_DIR): Inform libtool which
5348 subdirectory to use.
5349 (support for -pipe): Move after LT_INIT, since it relies on
5350 libtool internals.
5352 2006-05-05 Eric Blake <ebb9@byu.net>
5354 * Makefile.am (doc/m4.1): Use $@, not $(srcdir)/doc/$@.

5371 2005-12-05 Gary V. Vaughan <gary@gnu.org>
5373 * bootstrap (func_update_po): Synch with CVS GNU tar. wget 1.9.x
5374 and 1.10.x support --cache=off, so $WGETFLAGS are not necessary.
5375 Reported by Eric Blake <ebb9@byu.net>
5377 2005-12-04 Gary V. Vaughan <gary@gnu.org>
5379 * bootstrap (func_update_po): Test and set $WGETFLAGS to disable
5380 http caching as -C is no longer supported by wget 1.10.x.
5381 Reported by Eric Blake <ebb9@byu.net>
5383 2005-10-20 Gary V. Vaughan <gary@gnu.org>
5385 * m4/module.c (caller_id): To match libtool-2.0 interface, changed
5386 to ...
5387 (iface_id): ...an lt_dlinterface_id type.
5388 (m4__module_find): New abstraction for lt_dlhandle_fetch. Use
5389 throughout, instead of calling obsolete lt_dlhandle_find directly.

5401 po/ja.po, po/nl.po, po/pl.po, po/ru.po, po/sv.po: No need to store
5402 these files under source control anymore.
5403 Suggested by Eric Blake <ebb9@byu.net>
5405 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
5407 * ltdl/m4/m4-gnulib.m4: Update FSF contact address. Somehow this
5408 file escaped the address updates on 2005-05-01.
5410 2005-07-07 Gary V. Vaughan <gary@gnu.org>
5412 * bootstrap: Allow user overriding of gnulib-tool location, and
5413 correctly determine module source directories whether gnulib-tool
5414 is given as a relative or absolute path, or is found by searching
5415 PATH.
5416 Reported by Eric Blake <ebb9@byu.net>
5418 2005-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5420 * ltdl/m4/debug.m4 (m4_CHECK_DEBUGGING): Make sure that both $rm
5421 and $RM are defined for various versions of
5422 AC_LIBTOOL_COMPILER_OPTION.
5424 * bootstrap (AUTORECONF): New variable to allow user overriding of
5425 autoreconf path.
5427 2005-07-07 Gary V. Vaughan <gary@gnu.org>
5429 * doc/m4.texinfo (History): Add better notes on the ancestory of
5430 GNU m4, and other historical interest.
5432 2005-05-08 Gary V. Vaughan <gary@gnu.org>
5434 * m4/symtab.c (m4_symbol_rename): New function that performs a low
5435 level symbol rename.
5436 * m4/m4module.h (m4_symbol_rename): Declare it as part of the API.
5437 * modules/gnu.c (regsub): Factored out of m4_epatsubst_do...
5438 (m4_patsubst_do, m4_renamesyms_do): ...wrappers that use
5439 regsub...
5440 (erenamesyms, renamesyms): ...builtins that use these to implement
5441 macro renaming by regular expression.
5442 * doc/m4.texinfo (Erenamesyms and Renamesyms): Document them.
5443 * tests/generate.awk: Allow some forbidden `m4_' prefixed symbols
5444 to stop the new generated tests from choking.
5446 2005-05-07 Gary V. Vaughan <gary@gnu.org>
5448 Since most of the build is handled from a single Makefile.am now,
5449 we can teach make about the dependencies between the m4 binary and
5450 the preopened modules it is built against:
5452 * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
5453 preopened modules.
5454 * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
5455 of the preopened modules have changed.
5457 2005-05-07 Gary V. Vaughan <gary@gnu.org>
5459 * configure.ac (gl_MODULES): Add mkstemp for machines that don't
5460 have a native implementation.
5462 2005-05-06 Gary V. Vaughan <gary@gnu.org>
5464 * src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are
5465 handled already by gnu/exit.h.
5467 * configure.ac (gl_MODULES): Add assert to support a
5468 --disable-assert configure time option for NDEBUG setting.
5470 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.
5471 * bootstrap (src_modules): Add version-etc-fsf.
5472 * src/main.c (version_etc_copyright): Removed.
5474 * ltdl/m4/m4-getopt.m4 (m4_GETOPT): Synch with gnulib/getopt.m4.
5476 2005-05-04 Gary V. Vaughan <gary@gnu.org>
5478 * src/m4.h (__CYGWIN__, WIN32): Canonicalise Windows and Cygwin
5479 recognition macros.
5480 * src/freeze.c (produce_frozen_state): Use \n line-endings even
5481 on Windows, so that the frozen file reader will work.
5482 Reported by Josef T. Burger <bolo@bolo.com>
5484 2005-05-04 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
5486 Forward port of a patch that allowed m4-1.4.2 to compile on
5487 QNX 6.3:
5489 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
5490 sys/signal.h.
5491 * src/m4.h: And include them as appropriate.
5492 * src/main.c, src/stackovf.h: Don't include signal.h literally;
5493 m4.h will include the correct file.
5495 2005-05-04 Gary V. Vaughan <gary@gnu.org>
5497 * m4/m4private.h: Make errno visible for the sources patched
5498 below.
5500 2005-05-04 Paul Eggert <eggert@twinsun.com>
5502 * src/main.c (print_program_name_CB): Preserve errno, since
5503 M4ERROR relies on this.
5504 * modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
5505 * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
5506 * m4/path.c (m4_path_search): Don't let "free" trash errno when
5507 returning NULL.
5509 * m4/output.c (m4_insert_file): Don't assume errno has a valid
5510 value simply because fread returns zero. This fixes a
5511 portability bug reported by Marion Hakanson in
5512 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
5514 2005-05-04 Santiago Vila <sanvila@debian.org>
5516 * tests/stackovf.test: Use tempfile if available.
5518 2005-05-04 Robert Bihlmeyer <robbe@orcus.priv.at> (tiny change)
5520 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=92629
5521 * m4/output.c (m4_insert_file): Do not mix buffered and
5522 unbuffered I/O, as this breaks on the Hurd.
5524 2005-05-04 Gary V. Vaughan <gary@gnu.org>
5526 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
5527 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
5528 and libtoolize does a better job of ltdl importing now too, so
5529 take advantage of that while updating the tree:
5531 * acm4, config: Moved from here...
5532 * ltdl/m4, ltdl/config: ...to here.
5533 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
5534 src/Makefile.am, tests/Makefile.am: Removed...
5535 * Makefile.am: ...and migrated to here, with adjustments to
5536 compensate for relative path differences.
5537 * commit: Adjust relative paths.
5538 * configure.ac: Adjust relative paths.
5539 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
5540 patch.
5541 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
5542 the meanwhile, CVS HEAD libtool is needed.
5543 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
5544 stricly new enough, we also need a patch.
5545 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
5546 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
5547 (gl_MODULES): Don't list getopt and version-etc, as they don't
5548 belong in libm4.
5549 * bootstrap: After running gnulib-tool to import the listed
5550 modules, fetch getopt and version-etc into src manually.
5551 (ltdldir): Change to ltdl.
5552 * src/main.c: Adjust for changes in version-etc API.
5553 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
5554 but works when the getopt module isn't to be included in the lib.
5555 * README: Add note about patching autoconf and automake to
5556 bootstrap CVS m4.

5560 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=84416
5561 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
5562 empty file rather than to a nonexistent file. This closes a
5563 common security hole.
5564 * modules/m4.c (m4_maketemp): Implement the above, by using
5565 mkstemp rather than mktemp.
5567 2005-05-01 Gary V. Vaughan <gary@gnu.org>
5569 The FSF are moving offices today. Changed their contact address
5570 in all files from `59 Temple Place, Suite 330, MA 02111-1307' to
5571 `51 Franklin Street, Fifth Floor, MA 02110-1301'.
5573 2005-03-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)

5576 failures.
5578 2005-03-11 Per Bothner <per@bothner.com> (tiny change)
5580 * tests/Makefile (clean-local): Only run the testsuite cleanup

5597 2004-12-24 Eric Blake <ebb9@byu.net>
5599 * configure.ac (INCLUDE_STDBOOL_H): Account for gnulib's move
5600 to the gnu subdirectory.
5601 * acm4/m4-error.m4 (INCLUDE_ERROR_H): Likewise.
5602 * acm4/m4-obstack.m4 (INCLUDE_OBSTACK_H): Likewise.
5603 * acm4/m4-regex.m4 (INCLUDE_REGEX_H): Likewise.
5604 * m4/system_.h: Likewise, in non-configured includes.
5606 2004-10-14 Noah Misch <noah@cs.caltech.edu>,
5607 Gary V. Vaughan <gary@gnu.org>
5609 * m4/m4.c (m4_context_field_table, m4_context_opt_bit_table):
5610 Protect definitions from macro expansion under -DNDEBUG by
5611 parenthesising the expanded function names.
5612 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
5613 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
5614 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
5615 (m4_is_syntax_macro_escaped): Similarly protect function
5616 definitions from macro expansion under -DNDEBUG by #undefing the
5617 matching macro names before each definition. Also, move all the
5618 function definitions to the end of the file so that any
5619 invocations in the rest of the file pick up the fast macro
5620 versions.
5621 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)
5622 (m4_set_debug_file, m4_set_trace_messages)
5623 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
5624 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
5625 (m4_set_max_debug_arg_length_opt): New fast macro versions of the
5626 option setter functions.
5628 2004-09-23 Gary V. Vaughan <gary@gnu.org>
5630 * po/POTFILES.in: Reflect move of gnulib files from gnulib/m4
5631 to gnu.
5633 2004-09-23 Gary V. Vaughan <gary@gnu.org>
5635 * src/main.c: Include gnulib files from the correct directory.
5637 * gnulib/*: Don't store any of the gnulib files in arch, as they
5638 generate spurious changes.
5639 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
5640 gnulib macros now share our macro directory.
5641 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
5642 * bootstrap: Call gnulib-tool to import from the gnulib tree.
5643 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
5644 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
5645 the gettext macros from autopoint that overwrite the gnulib-tool
5646 imported versions. Import sources and Makefile.am into the `gnu'
5647 directory. Changed all callers.
5648 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
5649 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
5650 for imported modules.
5651 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
5652 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
5653 hardcoding the gnulib macros they wrap.
5655 2004-07-15 Gary V. Vaughan <gary@gnu.org>
5657 Latest CVS libtool can preload modules in libraries, including
5658 its own module loaders! Tweak m4 so that it doesn't try to treat
5659 libltdl's module loaders as m4 modules when freezing and on exit:
5661 * gnulib/acm4/*.m4: Don't store these files in arch since they
5662 generate spurious changes.
5663 * bootstrap: Simplify initial libtoolize call, since CVS
5664 libtoolize is smarter these days.
5665 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
5666 build.
5667 * m4/module.h (m4__module_exit): Missing declaration.
5668 * m4/m4private.h (m4__module_next): New function declaration.
5669 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
5670 encapsulation. Changed all callers.
5671 (m4__module_interface): New function to verify m4 loadable module
5672 interfaces.
5673 (m4__module_init): Register the interface validator.
5674 (m4__module_exit): Only close my own modules.
5675 * modules/m4.c (unistd.h): Provide missing declaration.
5676 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
5677 (m4_expand_ranges): More missing declarations.
5678 * modules/modtest.c (export_test): Ditto.
5679 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
5680 * src/main.c (main): Bump copyright year.
5681 * tests/modules.at: Fix sed syntax error.
5684 2004-06-17 Gary V. Vaughan <gary@gnu.org>
5686 Tweaking to enable compilation with latest CVS libtool and
5687 libltdl. We can't just dump the library files directly into the
5688 m4 directory anymore now that libltdl is built from pieces itself:
5690 * bootstrap: Rewritten to use latest libtoolize sanely, and to
5691 set up libltdl subdirectory.
5692 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
5693 gnulib subdirectory's config.
5694 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
5695 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
5696 macros from gnulib.
5697 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
5698 configure.ac, so use AC_WITH_LTDL instead.
5699 * Makefile.am (SUBDIRS): Add libltdl.
5700 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
5701 gl_INCLUDED_REGEX.
5702 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
5703 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
5704 (libm4_la_LIBADD): Add LIBLTDL.
5705 * m4/ltdl.c, m4/ltdl.h: Removed.
5706 * m4/m4module.h: Include canonical ltdl.h.
5707 * po/*.po: Updated.
5709 2004-06-14 Gary V. Vaughan <gary@gnu.org>
5711 * gnulib/import: Now updates makefile fragments, and configure.ac.
5712 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
5713 * gnulib/m4/Makefile.am: include it.
5714 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
5715 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
5716 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
5717 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
5718 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
5719 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,
5720 gnulib/acm4/lib-ld.m4, gnulib/acm4/lib-prefix.m4,
5721 gnulib/acm4/error.m4, gnulib/acm4/po.m4, gnulib/acm4/regex.m4,
5722 gnulib/acm4/stdbool.m4, gnulib/acm4/stdint_h.m4,
5723 gnulib/acm4/uintmax_t.m4, gnulib/acm4/ulonglong.m4,
5724 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
5725 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
5726 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
5727 import.
5728 * gnulib/m4/getopt_int.h: New source file from latest gnulib
5729 import.
5730 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
5731 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,
5732 gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
5733 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
5734 Updated source files from latest gnulib.
5736 2004-02-29 Gary V. Vaughan <gary@gnu.org>
5738 * config/mailnotify: New file for mailing commit notifications,
5739 imported from cvs-utils.
5740 * commit: Updated from cvs-utils and tweaked for m4.
5742 2003-12-01 Gary V. Vaughan <gary@gnu.org>
5744 * config/mkstamp: Updated from CVS libtool.
5745 * configure.ac: Generate a gnu coding standards compliant version
5746 number, and use it for the banner.
5747 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
5748 mhen the TIMESTAMP changes in ChangeLog, but the file modification
5749 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
5750 contain the previous version number.
5751 * src/main.c: Make --version output conform to the GNU standard.
5753 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
5754 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
5755 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
5756 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
5757 time_la_SOURCES): ...so that these are defaulted correctly, and
5758 can be removed from this file.
5759 (AM_LDFLAGS): Add -module...
5760 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
5761 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
5762 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
5763 the individual settings can be removed.
5764 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
5765 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
5766 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
5767 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
5768 time_la_LIBADD): ...so that these are picked up as a deplib of
5769 libm4 and don't need to be set explicitly.
5771 2003-11-18 Gary V. Vaughan <gary@gnu.org>
5773 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
5774 from the standard build. It is too fragile.
5776 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
5777 CVS libtool after merging m4 changes across to libtool.
5779 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
5780 * m4/path.c (search_path_add): Ditto.
5782 2003-11-13 Gary V. Vaughan <gary@gnu.org>
5784 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
5785 libtool tags we don't use in configure. This reduces the size
5786 of the script from over 1Mb to under 700Kb.
5788 2003-11-13 Gary V. Vaughan <gary@gnu.org>
5790 The import script was not written properly, and the last gnulib
5791 import was incomplete. Fixed that problem, and reimport our
5792 gnulib dependencies, which picks up the address calculation
5793 overflow checks described by Paul below. Also tweak the clients
5794 of the gnulib xalloc module not to use deprecated macros:
5796 * gnulib/import: Recurse through module dependencies rather than
5797 naively descending only one level.
5798 * configure.ac: Add calls to gnulib's strnlen and extension module
5799 macros.
5800 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
5801 extension modules.
5802 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
5803 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
5804 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
5805 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
5806 gnulib.
5807 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
5808 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
5809 place of `xcalloc (1, S)'.
5810 * m4/m4.c (m4_create): Likewise.
5811 * m4/m4private.h (m4_symbol_value_create): Likewise.
5812 * m4/symtab.c (symtab_fetch): Likewise.
5813 * m4/syntax.c (m4_syntax_create): Likewise.
5814 * src/freeze.c (reload_frozen_state): Likewise.
5815 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
5816 macro.
5817 * m4/symtab.c (m4_symtab_create): Likewise.
5819 2003-11-13 Gary V. Vaughan <gary@gnu.org>
5821 * tests/module.at: Comment typo.
5823 2003-10-10 Gary V. Vaughan <gary@gnu.org>
5825 * tests/modules.at (modules: importing): Apply some lateral
5826 thinking, and use AT_CHECK to compare the output of a sed pass
5827 over stderr against the canonical strerror string.
5829 * tests/modules.at (modules: importing): Edit the generated stderr
5830 output to canonicalize strerror output, before a comparison.

5834 Tru64UNIX perl is sloppy with namespace pollution. This patch is
5835 careful not to trip over the mess:
5837 * modules/perl.c: Some builds of perl install headers that contain
5838 `#define try __builtin_try'. Be sure to undefine that macro
5839 before `m4/hash.h' gets included, which uses the `try' symbol.
5840 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
5841 `false' before including `stdbool.h'.
5842 (DELETE): This symbol is not in m4's namespace, and is in any
5843 case only used internally...
5844 * m4/m4private.h (DELETE): ...so move it to here.

5849 Don't use XMALLOC and XCALLOC. Once we install the
5850 corresponding patch into gnulib, this will fix some
5851 address-calculation overflow bugs on hosts where calloc (A, B)
5852 returns garbage when A*B overflows.
5854 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
5855 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
5856 xmalloc, XCALLOC with xcalloc.
5857 * m4/m4.c (m4_create): Likewise.
5858 * m4/m4private.h (m4_symbol_value_create): Likewise.
5859 * m4/output.c (m4_output_init): Likewise.
5860 * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise.
5861 * m4/syntax.c (remove_syntax_attribute): Likewise.
5862 * src/freeze.c (reload_frozen_state): Likewise.
5863 * src/main.c (main): Likewise.
5865 2003-10-07 Gary V. Vaughan <gary@gnu.org>
5867 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
5868 gnulib/acm4 directories for aclocal m4 macros.
5869 * gnulib/Makefile.am (EXTRA_DIST): Removed.
5870 (MAINTAINERCLEANFILES): Add Makefile.in.
5871 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
5872 modules we use.
5873 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
5874 * gnulib/import: New file. Temporary script for updating gnulib
5875 imported files, until gnulib-tool is working.
5876 * gnulib/config/codeset.m4, gnulib/config/error.m4,

5920 gnulib/m4/version-etc.c, gnulib/m4/version-etc.h,
5921 gnulib/m4/xalloc.h, gnulib/m4/xmalloc.c: Updated from CVS
5922 gnulib with gnulib/import script.
5923 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
5924 guards ready for gnulib-tool to autoupdate on import.
5925 * config/debug.m4, config/gmp.m4, config/m4-error.m4,
5926 config/m4-gettext.m4, config/m4-obstack.m4, config/m4-regex.m4,
5927 config/stackovf.m4: Moved from here...
5928 * acm4/debug.m4, acm4/gmp.m4, acm4/m4-error.m4,
5929 acm4/m4-gettext.m4, acm4/m4-obstack.m4, acm4/m4-regex.m4,
5930 acm4/stackovf.m4: ...to here, to separate aclocal macros from
5931 configure time helper scripts.
5932 * config/error.m4: Removed; superceded by gnulib/acm4/error.m4.
5933 * m4/hash.c, m4/m4.c, m4/macro.c, m4/module.c, m4/output.c,
5934 m4/path.c, m4/symtab.c, m4/syntax, m4/system_.h, modules/m4.c,
5935 src/main.c, src/stackovf.c: s/xfree/free/g to comply with new
5936 gnulib xalloc.h.
5937 * src/main.c (version_etc_copyright): Only output the current
5938 year.
5939 (version_etc): Call with new variadic API.
5941 2003-09-16 Gary V. Vaughan <gary@gnu.org>
5943 * gnulib/m4/version-etc.c, gnulib/m4/version-etc.h: Import
5944 version-etc module from CVS gnulib.
5945 * po/POTFILES.in: Add gnulib/m4/version-etc.c.
5946 * src/Makefile.am: Build it.
5947 * src/main.c: Use it.
5949 * gnulib/m4/exit.h: Import exit module from CVS gnulib.
5950 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
5951 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
5952 exit.h instead.
5954 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
5955 Gary V. Vaughan <gary@gnu.org>
5957 * bootstrap: Separate options.
5958 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
5959 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
5960 not set.
5961 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
5962 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
5963 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
5964 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
5965 $(LTLIBINTL) for gettext support on cygwin.
5966 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
5967 have $(LTLIBINTL) from the preloaded module la files.
5968 * README: Remove the warning about using --disable-nls on Windows
5969 machines.
5971 2003-09-15 Gary V. Vaughan <gary@gnu.org>
5973 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
5974 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
5975 is required.
5977 2003-09-12 Gary V. Vaughan <gary@gnu.org>
5979 * doc/STYLE: Document the gnulib header naming conventions, and
5980 #include policy.
5981 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
5982 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,
5983 gnulib/m4/gettext.h, gnulib/m4/obstack.h, gnulib/m4/regex.h
5984 respectively.
5985 * gnulib/m4/Makefile.am: Remove the rules to build these headers.
5987 * gnulib/m4/strtol.c, gnulib/config/strtol.m4: Import strtol
5988 module from CVS gnulib.
5989 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
5990 (gl_FUNC_STRTOL): In favour of the module macro.
5992 2003-09-12 Gary V. Vaughan <gary@gnu.org>
5994 Replace the getopt code with CVS gnulib getopt. The source files
5995 detect whether they are in a glibc environment and preprocess away
5996 all of the code if there is a system getopt, so we can compile
5997 them into the m4 executable unconditionally:
5999 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
6000 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
6001 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
6002 macros.
6003 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
6004 version.
6005 * src/Makefile.am: Adjust.
6006 * src/main.c: Always include our shipped getopt.h.
6007 * po/POTFILES.in: Use new location of getopt.c.
6009 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6011 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
6012 * config/Makefile.am: Removed. Automake 1.8 distributes the files
6013 in this directory automatically.
6014 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
6016 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
6017 isn't set yet.
6018 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
6019 inline.
6020 * modules/Makefile.am (pkglibexecdir): Set it here.
6021 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
6023 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
6024 Import regex module from CVS gnulib.
6025 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
6026 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
6027 do extra substitutions for Makefile.
6028 * configure.ac: Use it.
6029 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
6030 from regex_.h if necessary.
6031 * m4/system_.h: Include the correct version of regex.h.
6032 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
6033 version.
6034 * po/POTFILES.in: Use new location of regex.c.
6036 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
6037 realloc.c: automake distributes these files already.
6039 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6041 Replace the xstrzdup code by importing the xstrndup module from
6042 CVS gnulib, along with its dependencies: strndup and strnlen:
6044 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
6045 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
6046 gnulib.
6047 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
6048 gnulib/config/strndup.m4: Ditto wrt strndup.
6049 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
6050 strnlen.
6051 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
6052 However, contrary to gnulib, we install xstrndup.h.
6053 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
6054 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
6055 is an artifact of the old m4 portability layer.
6056 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
6057 * m4/system_.h: Include xstrndup.h.
6058 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
6060 2003-09-11 Gary V. Vaughan <gary@gnu.org>
6062 Reimport the latest xalloc module from CVS gnulib, and adjust the
6063 m4 sources to take advantage of xalloc xfree. Also create a new
6064 macro DELETE with the same semantics as the old m4 XFREE macro,
6065 and carefully tweak callers:
6067 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
6068 gnulib.
6069 * m4/utility.c (xfree): Removed. This function is now supplied by
6070 gnulib xalloc.
6071 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
6072 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
6073 * m4/symtab.c (m4_symtab_create): Ditto.
6074 * m4/system_.h: Removed XFREE redefine.
6075 (DELETE): New macro with same functionality as the original m4
6076 XFREE macro, but based on xalloc.h now. Changed all callers.
6077 * src/main.c (main): Use XMALLOC macro.
6078 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
6079 instead of XFREE.
6080 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
6082 2003-09-10 Gary V. Vaughan <gary@gnu.org>
6084 Import the xalloc module from CVS gnulib, along with its
6085 dependencies: exitfail, malloc and realloc. We had different
6086 semantics for our XFREE and a function xfree() not supplied by
6087 gnulib, so also a bit of work to keep everything running
6088 smoothly:
6090 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
6091 (gl_XALLOC): Use gnulib equivalents.
6092 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
6093 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
6094 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
6095 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
6096 realloc.
6097 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
6098 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
6099 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
6100 imported modules.
6101 (pkgincdir): Removed. Use pkgincludedir instead.
6102 * m4/m4private.h (XFREE): xfree already checks for NULL.
6103 * m4/system_.h: Use xalloc module, and remove macros already
6104 supplied by xalloc.h.
6105 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
6106 moved the old definition from m4/xmalloc.c to here for now.
6108 2003-09-09 Gary V. Vaughan <gary@gnu.org>
6110 Import the error and progname modules from CVS gnulib. Our old
6111 error.c subsumed the functionality of both, so a little adjustment
6112 was required to accomodate the split in sources. Also added more
6113 wrapper macros to choose between a system installed error.h or our
6114 shipped gnulib error module:
6116 * m4/error.c, m4/error.h: Removed.
6117 * m4/Makefile.am: Adjust.
6118 (pkgincdir): Removed. Use pkgincludedir instead.
6119 * m4/module.h, src/main.c: Don't include `m4/error.h'.
6120 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
6121 error.h.
6122 * gnulib/m4/progname.c: Imported from CVS gnulib.
6123 * gnulib/m4/progname.h: Ditto.
6124 * src/main.c: Adjust to use progname module.
6125 * gnulib/m4/error.c: Imported from CVS gnulib.
6126 * gnulib/m4/error_.h: Ditto.
6127 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
6128 if appropriate, and link a local error.h if the system version is
6129 missing.
6130 (libgnu_la_SOURCES) Add progname module sources.
6131 * gnulib/config/error.m4: Imported from CVS gnulib.
6132 * gnulib/config/strerror_r.m4: Ditto.
6133 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
6134 to have ERROR_H for Makefile substitutions and tell system.h
6135 whether the system error.h should be used, or a locally installed
6136 version.
6137 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
6139 2003-09-09 Gary V. Vaughan <gary@gnu.org>
6141 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
6142 s/gettext_.h/gettext.h/.
6144 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
6145 automake have been fixed.
6147 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
6148 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
6149 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
6150 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
6152 2003-09-09 Gary V. Vaughan <gary@gnu.org>
6154 The gnulib obstack module requires the gnulib gettext module for
6155 systems that do not have GNU gettext installed. Because we use
6156 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
6157 that directory incase it clashes with the system gettext.h. This
6158 delta uses gettext_.h and extra rules in the Makefile to make a
6159 link to gettext.h when needed:
6161 * Makefile.am (auxdir): Removed. No longer used.
6162 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
6163 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
6164 moved.
6165 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
6166 Makefile based build.
6167 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
6168 of the macros are kept.
6169 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
6170 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
6171 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
6172 distributes these automatically.
6173 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
6174 warning from automake-1.7a.
6175 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
6176 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
6177 all callers.
6178 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
6179 wrt. m4_FUNC_OBSTACK.
6180 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
6181 wrt. m4_sys_STACKOVF.
6182 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
6183 wrt. _m4_LIB_GMP, m4_LIB_GMP.
6184 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
6185 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
6186 respectively.
6187 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
6188 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
6189 gettext.h link on deficient systems.
6190 (pkginc_HEADERS): Mention $(GETTEXT_H).
6191 (EXTRA_HEADERS): Mention gettext.h.
6192 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
6193 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
6194 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
6195 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
6196 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,

6204 2003-09-05 Gary V. Vaughan <gary@gnu.org>
6206 We can't mirror the gnulib directory structure here, since we need
6207 to be able to eg. `#include <m4/obstack.h>' from our source files,
6208 which is much easier if the local obstack.h is created in a
6209 directory named m4. Rather than trying to symlink everything into
6210 the m4 directory, now we build a libtool convenience library from
6211 the sources we get from gnulib and link that with libm4.la:
6213 * gnulib/config/extensions.m4: Imported from CVS gnulib.
6214 * gnulib/config/unlocked-io.m4: Ditto.
6215 * gnulib/m4/unlocked-io.h: Ditto.
6216 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
6217 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
6218 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
6219 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
6220 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
6221 * m4/Makefile.am: Adjust.
6222 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
6223 macros we redistribute.
6224 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
6225 library among others.
6226 (GNULIB_SRCS, GNULIB_MACROS): Removed.
6227 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
6228 * config/m4-obstack.m4: Adjust.
6229 * po/POTFILES.in: Adjust.
6230 * configure.ac: Reformatting. Call newly imported gnulib macros.
6231 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
6232 bogus calls of `#include "m4.h"'.
6233 * Makefile.am: INCLUDES has been deprecated in favour of
6234 AM_CPPFLAGS.
6235 * m4/Makefile.am: Ditto.
6236 * modules/Makefile.am: Ditto.
6237 * src/Makefile.am: Ditto.
6239 2003-09-05 Gary V. Vaughan <gary@gnu.org>
6241 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
6243 2003-09-04 Gary V. Vaughan <gary@gnu.org>
6245 Migrate the obstack support into the gnulib directories for easy
6246 synchronisation with upstream files in gnulib:
6248 * config/gnu-obstack.m4: Moved from here...
6249 * config/m4-obstack.m4: ...to here.
6250 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
6251 * m4/obstack.c, m4/obstack_.h: Moved from here...
6252 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
6253 * po/POTFILES.in: Adjust.
6254 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
6255 * m4/Makefile.am: Add a whole new section to link the obstack
6256 sources from the gnulib tree if necessary.
6257 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
6258 from gnulib.
6259 * config/m4-obstack.m4: Rewrite as a wrapper for
6260 gnulib/m4/obstack.m4.
6262 2003-09-04 Gary V. Vaughan <gary@gnu.org>
6264 GNU M4 currently builds with a number of files adapted from
6265 upstream sources. Recently the gnulib project on savannah.gnu.org
6266 has pulled together a great many of these externally maintained
6267 files. This delta is the beginnings of isolating those files
6268 maintained in gnulib to make it easy to synchronise M4 with the
6269 upstream files prior to releases.
6271 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
6272 directory.
6273 (SUBDIRS): Added new gnulib subdirectory.
6274 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
6275 * config/stdbool.m4: Moved from here...
6276 * gnulib/m4/stdbool.m4: ...to here.
6277 * m4/stdbool_.h: Moved from here...
6278 * gnulib/lib/stdbool_.h: ...to here.
6279 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
6280 distributed.
6281 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
6282 code to work with new stdbool_.h location.
6283 (gnulib_srcdir): New.
6285 2003-09-04 Gary V. Vaughan <gary@gnu.org>
6287 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
6288 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
6289 builds to work.
6290 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
6291 (EXTRA_DIST): Use it.
6293 * bootstrap: CVS autoreconf leaves file droppings. Remove
6294 aclocal.m4t incase autoreconf doesn't.
6296 2003-08-29 Gary V. Vaughan <gary@gnu.org>
6298 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
6299 the other gnulib imports, renamed to m4/obstack_.h.
6300 * m4/obstack.c: Updated from CVS gnulib.
6301 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
6302 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
6303 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
6304 about vpath already, and $top_srcdir upsets CVS Automake, so the
6305 $top_srcdir reference was removed.
6307 * m4/system-h.in: For consistency with the gnulib imports, renamed
6308 to m4/system_.h.
6309 * m4/Makefile (EXTRA_HEADERS): Adjust.
6310 * configure.ac (AC_CONFIG_FILES): Adjust.
6312 * m4/stdbool_.h: New file from gnulib for systems without their
6313 own.
6314 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
6315 * config/stdbool.m4: New file. Macros from gnulib for same.
6316 * configure.ac: Use it.
6318 2003-08-27 Gary V. Vaughan <gary@gnu.org>
6320 * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'`

6367 * src/main.c: Ditto.
6368 * src/stackovf.c: Ditto.
6370 * config/gmp.m4 (M4_AC_LIB_GMP): Use AC_INCLUDES_DEFAULT:
6371 ac_default_headers is an autoconf internal variable.
6372 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
6373 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
6375 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
6376 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
6377 delta.
6379 2003-08-15 Gary V. Vaughan <gary@gnu.org>
6381 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
6382 C99 bool.
6383 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
6384 possible or faking one with a typedef. Changed all callers.
6386 2003-08-15 Gary V. Vaughan <gary@gnu.org>
6388 Still cleaning up the users' module API, by taking out the stuff
6389 that isn't used by any existing modules, and moving specialised
6390 functions out of libm4 and into the module they are used by.
6392 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
6393 * m4/utility.c (m4_skip_space): ...to here the home of its only
6394 use, made static and renamed to `skip_space'. Changed all
6395 callers.
6396 * m4/m4module.h (m4_expand_ranges): Removed prototype.
6397 * m4/utility.c (m4_expand_ranges): Moved definition from here...
6398 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
6399 ltdl.
6400 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
6401 casting .
6402 * modules/gnu.c (builtin_syntax): Import and use in this
6403 builtin implementation.
6404 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
6405 Not used. Deleted.
6406 * m4/macro.c (trace_flush): Except here where the macro is now
6407 manually inlined.
6408 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
6409 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
6410 moved...
6411 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
6412 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
6414 2003-08-14 Gary V. Vaughan <gary@gnu.org>
6416 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
6417 compiler based AC_CHECK_HEADER that was introduced in
6418 autoconf-2.56.
6419 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
6420 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
6421 * configure.ac: Use renamed M4_AC_LIB_GMP.
6423 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
6424 macro that requires arguments! This stops the shell's bad
6425 substitution error at configure time.
6427 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
6428 variables to the testsuite shell. Set the value of USE_GMP so
6429 that the gmp test will run!
6430 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
6432 2003-08-11 Gary V. Vaughan <gary@gnu.org>
6434 Libltdl already has an excellent mechanism for accessing C symbols
6435 in modules. Lets use that! Remove all the exporting cruft and
6436 just use lt_dlsym in conjunction with a few conventions to
6437 simplify module writers' jobs. Also removed the table address
6438 caching code and otherwise simplified the module loader quite a
6439 bit. To access exported symbols in other modules, first the
6440 exporting module must name the symbols <modname>_LTX_<symname>,
6441 and the importing module must define a function type called
6442 <symname>_func. The importer then adds
6443 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
6444 that wishes to call out to the exported functions. Care must be
6445 taken that <symname> is non-NULL in the importing module incase
6446 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
6447 definition was in the importers source. Study
6448 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
6449 m4_module_import will attempt to automatically load a module
6450 required for symbol access if it is not loaded already.
6452 * TODO: Removed the items fixed in this delta.
6453 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
6454 module name.
6455 * m4/ltdl.h (lt_dlhandle_find): Declare it.
6456 * m4/module.c (m4_module_unload): Use it.
6457 * src/freeze.c (reload_frozen_state): Ditto.
6458 * m4/m4module.h (m4_export): Deleted. Removed all references.
6459 (M4_MODULE_IMPORT): New user convenience macro for importing
6460 arbitrary symbols from other modules.
6461 * m4/module.c (m4_module_import): New function to service
6462 M4_MODULE_IMPORT macro.
6463 (module_data): Removed. Looking up the tables on demand with
6464 lt_dlsym, rather than caching their addresses here simplifies the
6465 code substantially.
6466 (m4_get_module_builtin_table, m4_get_module_macro_table):
6467 Removed. Changed all callers.
6468 (set_module_macro_table, set_module_builtin_table): Renamed to
6469 install_macro_table and install_builtin_table respectively, and
6470 simplified now that the cache is no more.
6471 * modules/gnu.c (builtin_symbols): Use this new mechanism to
6472 import m4_dump_symbols from the m4 module.
6473 (builtin_esyscmd): Likewise for m4_set_sysval and
6474 m4_sysval_flush.
6475 * modules/m4.c (m4_export_table): Removed. Functions are
6476 addressed with the new mechanism which doesn't need this.
6477 (m4_set_sysval): New exported accessor function to prevent
6478 problems with variable access on inferior architectures.
6479 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
6480 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
6481 that we can have some type safety.
6482 * modules/modtest.c (export_test): C level exported function for
6483 testing the new import mechanism.
6484 * modules/import.c: New file for the import end of the test.
6485 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
6486 * tests/modules.at: New test cases for intermodule symbol
6487 importing.
6489 2003-08-07 Gary V. Vaughan <gary@gnu.org>
6491 * m4/m4module.c (m4_string): Moved from here...
6492 * m4/m4private.c (m4_string): ...to here.
6494 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
6496 2003-07-29 Gary V. Vaughan <gary@gnu.org>
6498 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
6499 already available to module writers through
6500 m4_{get,set}_nesting_limit_opt(), so moved from here...
6501 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
6502 (m4_create): Use it.
6504 2003-07-28 Gary V. Vaughan <gary@gnu.org>
6506 Aside from auditing path.c for m4module.h api obfuscation, this
6507 delta introduces the concept of private struct members in opaque
6508 data types to GNU m4: See the STYLE file for details.
6510 * TODO: Remind ourselves that a rewrite of path.c is needed.
6511 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
6512 Moved from here...
6513 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
6514 here and renamed. These type definitions are for internal api use
6515 only. Changed all callers.
6516 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
6517 Moved from here...
6518 * m4/path.c (search_path_env_init, search_path_add): ...to here
6519 and renamed. These calls were never used outside this file.
6520 Changed all callers.
6521 (dirpath): Moved functionality of this static declaration...
6522 * m4/m4private.h (struct m4): ...to this new internal only
6523 search_path field. Changed all callers.
6524 (m4__get_search_path): Added new internal api accessor.
6525 * m4/path.c (m4_search_path_info_new): Removed. Not used.
6526 (m4_include_init): Removed...
6527 * m4/m4.c (m4_create): ...because the new m4 field is now
6528 initialised here.
6529 (m4_delete): Recycle search_path memory.
6530 * src/main.c (main): Don't call m4_include_init now that it's
6531 gone!
6532 * doc/STYLE: Document convention for private fields in opaque
6533 ADTs.
6535 2003-07-24 Gary V. Vaughan <gary@gnu.org>
6537 Sometimes exporting the address of a symbol from a module isn't
6538 enough for other modules to call that symbol correctly. If
6539 custom data types are used for function parameters, they need to
6540 be known to the caller. This change introduces the concept of
6541 $(prefix)/include/modules/$(modulename).h to declare those
6542 structures. Also we move m4_dump_symbols from libm4 to the m4
6543 module to show this concept in action.
6545 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
6546 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
6547 exporting data structures from modules/m4.c.
6548 * modules/m4.c, modules/gnu.c: Include it.
6549 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
6550 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
6551 prototypes.
6552 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
6553 Moved from here...
6554 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
6555 ...to here, with slight renaming.
6556 (m4_export_table): Prototype and add m4_dump_symbols.
6557 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
6558 definition of m4_dump_symbols.
6559 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
6560 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
6562 2003-07-24 Gary V. Vaughan <gary@gnu.org>
6564 Create an export table in modules/m4.c in readiness for beefing up
6565 the module loader to track module exports and imports.
6567 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
6568 * m4/debug.c (m4_debug_flush_files): Moved...
6569 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
6570 * modules/gnu.c (builtin_esysval): Use it.
6571 * m4/m4module.h (m4_export): New type for declaring module symbols
6572 for export.
6573 * modules/m4.c (m4_export_table): List symbols exported from this
6574 module for use by other modules.
6576 2003-07-24 Gary V. Vaughan <gary@gnu.org>
6578 An experiment: There is loads of code in libm4 which should be in
6579 the m4 module, but is also used by another module. Just because
6580 some linkers won't cope with calls across dynamic runtime loaded
6581 objects I initially left the code in libm4. It will tidy the
6582 module api immensely if this code moves to the right place, I just
6583 need to remember to invent a suitable calling mechanism at some
6584 point. For now, only modules that are statically linked and
6585 preloaded will get this treatment, so the only platforms that will
6586 break are those that require all symbols to be resolved at link
6587 time.
6589 * TODO: Reminder that what I am doing could reduce portability
6590 unless I do something more robust later.
6591 * m4/m4module.h (m4_sysval): No longer exported from libm4.
6592 * m4/utility.c (m4_sysval): No longer declared in libm4.
6593 * modules/Makefile.am: Reformatting.
6594 * modules/m4.c (m4_sysval): Declare it at place of use.
6595 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
6597 2003-07-23 Gary V. Vaughan <gary@gnu.org>
6599 * m4/m4module.h: Reformatting and rearranging lines a bit.
6600 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
6601 all users.
6602 (m4_call_macro, m4_expand_input): Renamed...
6603 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
6604 callers.
6605 (m4_expansion_level, m4_process_macro): Moved...
6606 * m4/macro.c (expansion_level, process_macro): ...to here, and
6607 made static.
6609 * m4/m4module.h (program_name): Not used by modules at all, so
6610 moved...
6611 * src/main.c (program_name): ...to here.
6612 (print_program_name): Renamed...
6613 (print_program_name_CB): ...to conform to the STYLE guide.
6615 2003-07-23 Gary V. Vaughan <gary@gnu.org>
6617 More refactoring of the m4module.h API. Replace #defines with an
6618 enum, and move non-public functions out of the public API.
6620 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
6621 inclusion.
6622 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
6623 * m4/debug.c (m4_debug, trace): Moved...
6624 * m4/m4private.h (struct m4): ...to fields of this struct.
6625 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
6626 for the new fields.
6627 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
6628 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
6629 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
6630 * m4/m4module.h (m4_context_field_table): Add entries for new
6631 debug_file and trace_messages fields.
6632 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
6633 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
6634 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
6635 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
6636 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
6637 (m4_is_debug_bit): New macro to simplfy checks against the debug
6638 bits above.
6639 (m4_trace_format, m4_trace_header, m4_trace_flush)
6640 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
6641 prototypes.
6642 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
6643 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
6644 * m4/macro.c (trace_format, trace_header, trace_flush)
6645 (trace_prepre, trace_pre, trace_post): ...to these newly static
6646 functions, since they are only ever used from this file. Changed
6647 all callers.
6649 2003-07-17 Gary V. Vaughan <gary@gnu.org>
6651 Change the macros for checking syntax so that matching against
6652 multiple possible syntax classes can be done with a single
6653 comparison some of the time. The various classes are now bits of
6654 an int that can be checked with bitwise logic operators.
6656 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
6657 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
6658 (M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)
6659 (M4_SYNTAX_ASSIGN, M4_SYNTAX_ALPHA, M4_SYNTAX_NUM)
6660 (M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)
6661 (M4_SYNTAX_ECOMM): Replaced #defines with an enum.
6662 (M4_SYNTAX_ALNUM): Removed. Changed all callers.
6663 (M4_IS_IGNORE, M4_IS_OTHER, M4_IS_SPACE, M4_IS_OPEN, M4_IS_CLOSE)
6664 (M4_IS_COMMA, M4_IS_DOLLAR, M4_IS_ACTIVE, M4_IS_ESCAPE)
6665 (M4_IS_ASSIGN, M4_IS_ALPHA, M4_IS_NUM, M4_IS_LQUOTE, M4_IS_RQUOTE)
6666 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
6667 Replace all calls with invocations of these...
6668 (m4_is_syntax, m4_has_syntax): ...New macros.
6669 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
6670 is no longer required with new macros. Changed all callers.
6672 2003-07-15 Gary V. Vaughan <gary@gnu.org>
6674 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
6675 values are returned as part of the internal interface, so they
6676 need to be moved...
6677 * m4/private.h: ...to here.
6678 * m4/macro.c (expand_token): Check for out of range
6679 m4_peek_input() results before looking up in the syntax table.
6680 (collect_arguments): Ditto.
6682 * NEWS: Note `$' syntax class.
6684 2003-07-08 Paul Eggert <eggert@twinsun.com> and
6685 Gary V. Vaughan <gary@gnu.org>
6687 Conform to POSIX if the POSIXLY_CORRECT environment is set.
6688 --traditional `define' now smashes all the definitions.
6690 * NEWS: Explain this.
6691 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
6692 (Extensions): Explain that extensions that are incompatible with
6693 POSIX are disabled if POSIXLY_CORRECT is set.
6694 (Incompatibilities): Remove.
6695 (Define, Other Incompat): Explain difference
6696 between GNU and POSIX behavior of define, pushdef, popdef.
6697 * m4/m4.c (m4_get_posixly_correct_opt): New undef.
6698 * m4/m4module.h (m4_context_opt_bit_table): Add POSIXLY_CORRECT entry.
6699 * m4/m4private.h (M4_OPT_POSIXLY_CORRECT_BIT): New macro.
6700 (m4_get_posixly_correct_opt): New macro.
6701 * m4/m4macro.c (m4_process_macro): Disable $10, $abc etc. if
6702 POSIXLY_CORRECT.
6703 * modules/m4.c (builtin_functions): defn now takes any number of args.
6704 (builtin_define): Smash all the definitions if
6705 POSIXLY_CORRECT.

6708 if POSIXLY_CORRECT.
6709 * src/main.c (main): Set posixly-correct behavior if either
6710 POSIXLY_CORRECT is set, or if -G is given.
6711 * tests/builtins.at: New test for smashed definitions.
6713 2003-06-27 Gary V. Vaughan <gary@gnu.org>
6715 * doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
6716 * m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
6717 not to slow the parser down.
6718 (M4__IS_STRING): New macro to test string syntax class membership.
6719 * m4/syntax.c: Adjust docucomment.
6720 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
6721 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
6722 * m4/input.c (init_builtin_token): Comment typo.
6723 (m4__next_token): Comment typo.
6724 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
6725 by using the new M4__IS_STRING macro.
6726 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
6727 variable references in macro expansions.
6729 * doc/m4.texinfo (Eregexp and Regexp): Typo.
6730 (Epatsubst and Patsubst): Typo.
6731 (Eval): Typo.
6733 2003-06-26 Gary V. Vaughan <gary@gnu.org>
6735 Move the global variables that pertain to syntax to a new `struct
6736 m4_syntax_table', and then add one of these to `struct m4'. The
6737 ripple effect through the code to both change formerly global
6738 references, and make sure a suitable context is available in
6739 lexical scope is disproportionately large compared to the size of
6740 the change proper. This change is a large part of decoupling
6741 syntax.c from the rest of the code that uses it.
6743 * m4/m4private.h (struct m4): Add a syntax field.
6744 * m4/m4.c (m4_create): Initialise it,
6745 (m4_delete): Recycle it.
6746 (m4_get_symtab): Remove hand coded version...
6747 (m4_get_symbol_table): ...and generate this with cpp. Changed all
6748 callers.
6749 * m4/m4module.h (m4_context_field_table): Add an extra field so we
6750 can generate m4_get_symbol_table. Add a new row for
6751 m4_get_syntax_table.
6752 (M4SYNTAX): Syntactic sugar for module writers.
6753 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
6754 (m4_syntax_table): New home for syntax related formerly global
6755 variables.
6756 * m4/m4private.h (struct m4_syntax_table): Define it.
6757 * m4/input.c (m4_input_init): Initialisation of these formerly
6758 global variables moved...
6759 * m4/syntax.c (m4_syntax_create): ...to here.
6760 * m4/input.c (m4_input_exit): And similarly, recycling of the
6761 memory used by those values moved...
6762 * m4/syntax.c (m4_syntax_delete): ...to here.
6763 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
6764 Moved to m4/m4private.h.
6765 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
6766 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
6767 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
6768 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
6769 objects. Changed all callers that used to directly access the
6770 global equivalents.
6771 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
6772 Removed and incorporated into m4_syntax_table structure.
6773 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
6774 * m4/syntax.c (m4_set_syntax): Now returns an error status,
6775 instead of requiring a `struct m4' to generate its own errors.
6776 Changed all callers.
6777 * src/main.c (main): Now that the syntax table is initialised as
6778 part of m4_create, we have to manually wipe the syntax entries if
6779 we are about to read a frozen file.
6781 2003-06-26 Gary V. Vaughan <gary@gnu.org>
6783 * doc/STYLE: Added notes on callback naming schemes.
6785 * m4/module.c (m4_set_module_macro_table)
6786 (m4_set_module_builtin_table): Declarations weren't changed when
6787 definitions were renamed on 2003-06-19.
6789 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
6790 neither used nor particularly appropriate since it exposes the
6791 internal workings of the hash module. I haven't yet decided
6792 whether to remove it entirely.
6794 2003-06-20 Gary V. Vaughan <gary@gnu.org>
6796 Two related changes, and a huge knockon effect throughout the
6797 source: Moved the option variables out of global space and into
6798 `struct m4'; made `m4_symtab' a real datatype, so that its api
6799 is not marred passing `struct m4' around just so it can decide
6800 whether to keep traced symbol names or not. Added setters and
6801 getters for the formerly global option variables, and obviously
6802 changed a vast number of functions to take a `struct m4' and use
6803 the getter funcs to find option values.
6805 * m4/utility.c (interactive, sync_output, debug_level)
6806 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
6807 (max_debug_argument_length, warning_status, nesting_limit)
6808 (discard_comments): Removed.
6809 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
6810 (debug_level, max_debug_argument_length, prefix_all_builtins)
6811 (suppress_warnings, discard_comments, interactive, sync_output):
6812 Removed from here...
6813 * m4/m4private.h (struct m4): ...and equivalent fields added to
6814 this structure.
6815 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
6816 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
6817 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
6818 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
6819 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
6820 macros for the new fields.
6821 * m4/m4module.h (m4_context_field_table)
6822 (m4_context_opt_bit_table): Helper macros used to generate
6823 prototypes, setters and getters for new option fields
6824 consistently.
6825 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
6826 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
6827 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
6828 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
6829 (m4_get_interactive_opt, m4_get_sync_output_opt)
6830 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
6831 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
6832 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
6833 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
6834 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
6835 setter and getter functions generated by cpp from
6836 m4_context_field_table and m4_context_opt_bit_table, exported as
6837 part of the module api. Changed all callers.
6838 * m4/symtab (struct m4_symtab): Used as the concrete type for
6839 m4_symtab now.
6840 (m4_symtab_create): Allocate and initialise a new struct.
6841 (m4_symtab_apply): New function that works like m4_hash_apply, but
6842 with different callbacks specific to symbol tables. Changed all
6843 callers.
6844 (symbol_destroy, arg_destroy, arg_copy): Renamed
6845 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
6846 they have unused parameters for a reason!
6847 (dump_symbol_CB): New callback to dump the contents of a single
6848 symbol.
6849 (symtob_dump): Rewritten in terms of dump_symbol_CB.
6850 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
6851 Changed all callers.
6852 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
6853 of the contained `m4_symtab' at the `no_gnu_extensions' field.
6854 Although I'm not convinced these semantics are correct, they are
6855 at least consistent with how things were before this delta. Also
6856 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
6858 2003-06-19 Gary V. Vaughan <gary@gnu.org>
6860 Tie down the interface to libm4 some more. Make more structures
6861 opaque to modules by moving them to m4private.h, and writing
6862 setters and getters. To win back the speed penalty for doing this
6863 also wrote macroized versions that do know about structure layout
6864 in m4private.h and #include that file into modules when NDEBUG is
6865 defined at compile time. There are still some accessor macros in
6866 m4private.h that need to go, but that is not necessary to clean
6867 the module api up.
6869 * m4/m4module.h (m4_symbol_type): Moved...
6870 * m4/m4private.h (m4__symbol_type): ...to here.
6871 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
6872 (m4_set_symbol_traced, m4_set_symbol_name_traced)
6873 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
6874 (m4_get_symbol_func, m4_symbol_value_create)
6875 (m4_symbol_value_delete, m4_set_symbol_value_text)
6876 (m4_set_symbol_value_func): New exported api to symbols.
6877 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
6878 and m4_is_symbol_value_func.
6879 * m4/m4module.h: Prototype these guys.
6880 * m4/module.c (m4_set_module_macro_table)
6881 (m4_set_module_builtin_table): Make these static, there is no
6882 reason to pollute the api with them.
6883 * m4/m4private.h: Reformatting.
6884 (m4_get_symtab): Only define when NDEBUG is defined.
6885 (m4_get_symbol_value, m4_get_symbol_traced)
6886 (m4_set_symbol_traced, m4_set_symbol_name_traced)
6887 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
6888 (m4_get_symbol_func, m4_symbol_value_create)
6889 (m4_symbol_value_delete, m4_set_symbol_value_text)
6890 (m4_set_symbol_value_func): Macro implementations of the new
6891 functions when NDEBUG is defined.
6892 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
6893 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
6894 Superceded by the above. All callers changed.
6895 (M4ARG): Removed. This is no longer different to the
6896 m4/m4module.h definition.
6897 * modules/gnu.c, modules/m4.c: Only include m4private.h when
6898 NDEBUG is defined. That way we exercise the same (albeit slower)
6899 api that external modules must use.
6901 2003-06-18 Gary V. Vaughan <gary@gnu.org>
6903 Renamed some of the types and their accessors to make more sense.
6904 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
6905 has a stack of SYMBOL_VALUEs.
6907 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
6908 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
6909 m4_get_symbol_value_type, m4_get_symbol_value_text,
6910 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
6911 Changed all callers.
6912 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
6913 (m4_get_token_type): Renamed
6914 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
6915 to the internal api.
6916 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
6917 s/TOKEN_/VALUE_/
6918 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
6919 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
6920 (m4__token_type): Moved here from m4module.h.
6921 (m4__next_token): Renamed from m4_next_token.
6922 * m4/symtab.c: Removed some of the parameterised macro support
6923 functions for modularisation later.
6924 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
6925 m4_hash_dup to perform a true deep copy of the SRC.
6926 (arg_copy): Callback for m4_symbol_value_copy.
6927 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
6928 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
6929 m4_get_symbol_value_func. Changed all callers.
6931 2003-06-18 Gary V. Vaughan <gary@gnu.org>
6933 Tidy up style of hash.[ch] in accordance with doc/STYLE.
6935 * m4/hash.c: Internal symbol renaming and formatting.
6936 (m4_hash_dup): New function to facilitate deep copies of hash
6937 tables.
6938 (m4_hash_apply_func): Returns a void* now, which is a richer type
6939 for returning exceptions (NULL means keep going).
6940 (m4_hash_apply): Ditto.
6941 * m4/hash.h: Declare exported symbols with an explicit extern.
6942 Reformated.
6944 2003-06-17 Gary V. Vaughan <gary@gnu.org>
6946 Still refactoring furiously. This delta represents a change in
6947 semantics to symtab.c. Instead of building temporary m4_tokens
6948 in the caller, and copying fields in the methods, we now create
6949 the actual m4_token for hashing in the caller so the methods just
6950 slot them in directly. Also, this means that we don't lookup a
6951 symbol and get back an allocated but VOID token to copy fields
6952 into, we create the token we want to push and pass that to
6953 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
6954 a few other small changes to stop knowledge of the implementation
6955 of symtab.c leaking out into other files.
6957 * m4/macro.c (expand_argument): Comment typo corrected.
6958 * m4/symtab.c (symtab_fetch): New function to fetch the address of
6959 an interned symbol.
6960 (m4_symbol_pushdef): Take an extra value parameter and use this
6961 directly as the new top of the value stack. All callers changed
6962 to build a token and pass responsibility for memory in, rather
6963 than copying as we used to.
6964 (m4_symbol_define): Also use the new value parameter directly as a
6965 replacement for the top of the value stack. All callers changed
6966 to build a token as above.
6967 (m4_set_symbol_traced): New function to set the traced bit on the
6968 named symbol, creating it if necessary.
6969 (symbol_popval): The guts of the old m4_symbol_popdef.
6970 (m4_symbol_popdef): Use it.
6971 * m4/builtin.c (m4_symbol_set_token): Removed,
6972 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
6973 replaced...
6974 * m4/module.c (m4_set_module_builtin_table)
6975 (m4_set_module_macro_table): ...with these more orthogonal
6976 functions.
6977 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
6978 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
6979 required.
6980 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
6981 (m4_arg_signature_parse): Moved...
6982 * m4/symtab.c: ...to here.
6983 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
6984 screw something up. Moved...
6985 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
6986 actually does a proper deep copy of source to dest.
6988 2003-06-16 Gary V. Vaughan <gary@gnu.org>
6990 Further refactoring to stabilise the module API. Renaming some
6991 functions for orthogonality, and judicious definition migration to
6992 move things out of the set of exported symbols.
6994 * doc/STYLE: New file. Notes on coding style.
6995 * m4/m4module.c: Updated bitrotted docucomment at the top of the
6996 file.
6997 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
6998 m4_get_module_name, m4_get_module_builtin_table,
6999 m4_get_module_macro_table which are verb phrases. Changed all
7000 callers.
7001 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
7002 Moved to...
7003 * m4/module.c (m4_set_module_builtin_table)
7004 (m4_set_module_macro_table): ...here, and renamed. Changed all
7005 callers.
7006 * m4/m4module.c (m4_module_data): This...
7007 * m4/m4private.c (struct m4_module_data): ...and this...
7008 * m4/module.c (module_data) ...consolidated here and no longer
7009 exported. Changed all callers.
7011 2003-06-16 Gary V. Vaughan <gary@gnu.org>
7013 Begin work on lifting the curse of the global variables. To start
7014 with create a `struct m4' context container, and replace
7015 `m4__symtab' with `context->symtab' throughout. This means
7016 initialising a context container in main, and adjusting many
7017 functions between main and the module entry points so that the
7018 container gets passed through. It would have been nice to
7019 defer this until after 1.5, but it has a major effect on the
7020 user's module writing ABI, so it needs to be addressed now - at
7021 least in the areas that impact the ABI. An interrelated change
7022 in the symtab API removes the dependency on a global symbol table,
7023 and instead focuses on a passed table (from the context
7024 container).
7026 * TODO: Reminders for finishing context functionality.
7027 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
7028 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
7029 global variables and eventually allow m4 to be reentrant.
7030 * m4/m4private.h (m4): Define the new structure here...
7031 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
7032 don't carry the overhead of a function call.
7033 * m4/m4module.h: Prototype extern functions from m4/m4.c.
7034 (m4): Declare type for new struct m4 objects.
7035 (M4SYMTAB): User macro to ease finding the symbol table for the
7036 current context for module developers.
7037 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
7038 verb.
7039 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
7040 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
7041 (m4_call_macro, m4_dump_symbols, m4_expand_input)
7042 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
7043 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
7044 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
7045 m4* context parameter. Changed definitions and all callers.
7046 (m4_symtab): Alias for m4_hash to decouple the
7047 m4_symtab api from m4_hash.
7048 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
7049 m4_hash.
7050 (m4_symtab_create): New function to return an initialised
7051 m4_symtab.
7052 (m4_symtab_delete): New function to delete an m4_symtab's memory.
7053 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
7054 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
7055 instead of simply using the global m4__symtab. Changed
7056 definitions and all callers.
7057 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
7058 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
7059 * src/main.c (main): Create a context and use that instead of the
7060 former global m4__symtab.
7062 2003-06-13 Gary V. Vaughan <gary@gnu.org>
7064 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
7065 to the callback. Callbacks should not need to hardcode the
7066 hashtable they are working from, nor should we have to waste the
7067 userdata parameter to pass the table in.
7068 * m4/hash.h (m4_hash_apply_func): Require the initial table
7069 parameter.
7070 * m4/symtab.c (symtab_destroy): Use the passed table instead
7071 of hardcoding m4__symtab.
7072 (m4_symbol_popdef): Don't use the userdata parameter to pass the
7073 table to arg_destroy.
7074 (arg_destroy): Use the hash parameter, ignore userdata.
7075 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
7076 prototype.
7077 (traceon, traceoff): Call set_trace with the extra initial
7078 parameter.
7080 2003-06-13 Gary V. Vaughan <gary@gnu.org>
7082 More refactoring to stabilise the module api, this time for
7083 symtab.c. Additionally, start to pay attention to function names
7084 that don't contain a verb like they should.
7086 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
7087 wrapper for m4_hash_apply to decouple the symtab module from the
7088 hash module.
7089 (m4_symbol_builtin, m4_symbol_macro): Renamed to
7090 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
7091 callers.
7092 (m4_symbol_delete): Create a macro version to save a function
7093 call.
7094 (m4_token_t, m4_data_t): These violate the POSIX reserved
7095 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
7096 all callers.
7097 (m4_token_type): Renamed to m4_token_get_type.
7098 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
7099 (m4_symtab_exit): Removed from the exported module
7100 api...
7101 * m4/m4private.h (m4__symtab, m4__symtab_init)
7102 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
7103 renamed and added to the internal api. Changed all callers.
7104 (m4_symtab_apply): A faster macro version of the function for
7105 users of the internal api.
7106 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
7107 symbol_destroy and arg_destroy.
7108 (symtab_debug): Added a prototype.
7109 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
7110 so that callers in this file get the faster macro versions from
7111 m4/m4private.h.
7113 2003-06-12 Gary V. Vaughan <gary@gnu.org>
7115 Refactoring modules to rationalise the API into an external
7116 documented (eventually!) API for use by modules in the `m4_'
7117 namespace declared in m4/m4module.h, an internal API between the
7118 source files we ship (including our shipped modules) in the `m4__'
7119 namespace declared in m4/m4private.h and making the rest as
7120 cohesive as possible with liberal use of the `static' keyword.
7121 This change represents an audit to m4/module.c along these
7122 guidelines.
7124 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
7125 Removed. No longer used.
7126 (m4_module_close): Removed prototypes.
7127 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
7128 from the exported module api...
7129 * m4/m4private.h (m4__module_init, m4__module_open)
7130 (m4__module_exit): ...and renamed and added to the internal api.
7131 Changed all callers.
7132 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
7133 Centralised definitions after renaming...
7134 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
7135 (M4_FINISH_SYMBOL): ...and removing from here.
7136 (m4_module_dlerror, m4_module_remove, m4_module_close)
7137 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
7138 module_remove, module_close and caller_id.
7139 (MODULE_SELF_NAME): New macro to make reporting self errors
7140 easier.
7141 (m4_module_load, module_close, module_remove): Use it.
7142 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
7143 name.
7144 * src/main.c (main): Use it.
7146 2003-06-12 Gary V. Vaughan <gary@gnu.org>
7148 * README: Remove references to --enable-changeword, which has been
7149 removed from the code.
7151 2003-06-11 Gary V. Vaughan <gary@gnu.org>
7153 Getting rid of the annoying bug with configure --enable-debug,
7154 which spewed -e: command not found errors. This was an interaction
7155 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
7156 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
7157 branch-1-5) to get the full fix.
7159 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
7160 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
7161 and then use the probed value of $SED.
7162 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
7163 this, it messes up the AC_REQUIRE stack.
7165 2003-06-10 Gary V. Vaughan <gary@gnu.org>
7167 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
7168 the destroy callback.
7169 (m4_arg_destroy): Use the hash address to free the hash node key
7170 field.
7172 2003-06-06 Gary V. Vaughan <gary@gnu.org>
7174 First cut at formal parameters in macros.
7176 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
7177 * m4/xstrzdup.c: New file.
7178 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
7179 associative array of parameter names to details.
7180 (m4_symbol_token): Capture macro names with parameter lists.
7181 (m4_arg_signature_parse): And build an associative array to hang
7182 from the symbol structure to map names to details.
7183 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
7184 m4_hash_resize idiom. Now that we potentially add a little hash
7185 table to many of the entries in the symbol table, added an extra
7186 arg to set the initial size. Changed all callers.
7187 (m4_hash_apply): New function that is basically a generalised
7188 version of...
7189 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
7190 all callers to call m4_hash_apply instead.
7191 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
7192 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
7193 m4_arg_signature association that might be attached to the symbol,
7194 * m4/hash.h (m4_hash_apply_func): Replacement type for...
7195 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
7196 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
7197 parameter lists.
7198 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
7199 (M4_IS_IDENT): Detect characters that can be safely used in
7200 parameter names.
7201 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
7202 * m4/macro.c: Corrected grammar in some comments. Use `token'
7203 rather than `td' for m4_token variables.
7204 (m4_process_macro): If we find a dollar followed by some
7205 M4_IS_IDENT characters, replace that with the contents of the argv
7206 entry with offset stored in the m4_token_arg associated with the
7207 collected identifier.
7209 2003-06-05 Gary V. Vaughan <gary@gnu.org>
7211 Begin preparations for supporting formal parameters in m4 macros.
7213 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
7214 the details of a formal parameter.
7215 (m4_token): Add an arg_signature member to hold a hash table for
7216 looking up formal parameters.
7217 * m4/input.c: Update more bitrotted comments.
7218 (m4_push_builtin): Initialise arg_signature member.
7219 (init_builtin_token): Copy arg_signature member.
7220 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
7221 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
7222 replace...
7223 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
7224 (m4_macro_pushdef, m4_macro_define): ...these, And...
7225 (m4_symbol_token): ...wrapped around this new function, which
7226 vastly simplifies the arguments required by the functions it
7227 replaces.
7228 Changed all callers.
7230 2003-06-05 Gary V. Vaughan <gary@gnu.org>
7232 * m4/macro.c: Format changes.
7234 2003-06-04 Gary V. Vaughan <gary@gnu.org>
7236 * m4/input.c: Updated various bitrotted comments.
7237 (m4_push_builtin): Just pass the whole m4_token, rather than
7238 extracting all the fields in the caller. This also allows us to
7239 check the token type for consistency.
7240 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
7241 Renamed to builtin_funcs, builtin_peek, builtin_read,
7242 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
7243 the code. Changed all callers.
7244 (struct input_block): Similarly renamed u_m member to u_b, and
7245 changed all callers.
7246 (m4_next_token): Use bzero to initialise the data fields.
7247 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
7249 2003-05-29 Gary V. Vaughan <gary@gnu.org>
7251 These changes were necessary to get m4 to build on my iBook
7252 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
7253 (GCC) 3.1 20020420 (prerelease)":
7255 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
7256 inclusion of module loader headers.
7257 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
7258 * m4/Makefile.am: Ditto.
7259 (libm4_la_LIBADD): Added $(LTLIBINTL).
7260 * m4/utility.c (program_name): Removed declaration in favour of
7261 the one already in error.c!
7262 * m4/m4module.h (program_name): Define to program_invocation_name
7263 when using GNU C library. Use an explicit extern declaration.
7264 (interactive, sync_output, debug_level, hash_table_size)
7265 (no_gnu_extensions, prefix_all_builtins, max_debug_argument_length)
7266 (suppress_warnings, warning_status, nesting_limit, discard_comments)
7267 (lquote, rquote, bcomm, ecomm, m4_bad_argc, m4_skip_space)
7268 (m4_numeric_arg, m4_shipout_int, m4_shipout_string, m4_dump_args)
7269 (m4_debug, m4_debug_init, m4_debug_exit, m4_debug_decode)
7270 (m4_debug_flush_files, m4_debug_set_output, m4_debug_message_prefix)
7271 (m4_trace_prepre, m4_trace_pre, m4_trace_post, m4_sysval)
7272 (m4_expansion_level, m4_expand_ranges, m4_expand_input)
7273 (m4_call_macro, m4_process_macro, m4_syntax_table, m4_current_file)
7274 (m4_current_line, m4_current_diversion, m4_output_current_line):
7275 Don't rely on default, use an explicit extern.
7276 * m4/error.h (error, error_at_line, error_print_progname)
7277 (error_message_count, error_one_per_line): Ditto.
7278 * m4/ltdl.c: Update from CVS libtool.
7279 * m4/ltdl.h: Ditto.
7280 * commit: Update from CVS cvs-utils.
7282 2002-11-04 gettextize <bug-gnu-gettext@gnu.org>
7284 * po/Makefile.in.in: Upgrade to gettext-0.11.5.
7285 * po/boldquot.sed: New file, from gettext-0.11.5.
7286 * po/en@boldquot.header: New file, from gettext-0.11.5.
7287 * po/en@quot.header: New file, from gettext-0.11.5.
7288 * po/insert-header.sin: New file, from gettext-0.11.5.
7289 * po/quot.sed: New file, from gettext-0.11.5.
7290 * po/remove-potcdate.sin: New file, from gettext-0.11.5.
7291 * po/Rules-quot: New file, from gettext-0.11.5.
7293 2002-11-04 Akim Demaille <akim@epita.fr>
7295 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
7296 running m4 itself.
7297 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
7299 2002-11-04 Akim Demaille <akim@epita.fr>
7301 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
7303 2002-11-04 Akim Demaille <akim@epita.fr>
7305 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
7306 used as `external', and Libtool 1.4.3.
7307 (LINGUAS): Remove.
7308 (LTLIBOBJS): Don't play with it.
7309 * intl/: Remove.
7310 * Makefile.am (SUBDIRS): Remove intl.
7311 (ACLOCAL_AMFLAGS): Add -I config.
7312 (EXTRA_DIST): Add config/config.rpath.
7313 * po/LINGUAS: New.
7314 * po/Makevars: New.
7315 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
7317 2002-05-29 Gary V. Vaughan <gary@gnu.org>
7319 Preparations for refactoring syntax tables to allow reverse
7320 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
7321 speed of normal lookups in an array of unsigned short.
7323 * m4/input.c (single_quotes, single_comments, use_macro_escape):
7324 Moved from here...
7325 * m4/m4private.h (m4__single_quotes, m4__single_comments,
7326 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
7327 is for internal symbols which unavoidably pollute the global
7328 namespace, but are not published APIs.
7329 Adjusted all callers.
7330 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
7331 m4_set_comment, m4_set_syntax, set_syntax_internal,
7332 unset_syntax_attribute): Moved from this file...
7333 * m4/syntax.c: New. ...to this file.
7334 Also added an m4_syntax_exit stub for orthogonality.
7335 * src/main.c (main): Use it.
7336 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
7337 * m4/m4module.h: Reformatting. New prototypes.
7339 2002-05-29 Gary V. Vaughan <gary@gnu.org>
7341 * bootstrap (aclocal_apiversion): The aclocal apiversion is
7342 distinct from the automake release number (in that the apiversion
7343 apparently has no micro-version-component).
7344 (aclocal_apilibdir): Use it.
7346 2002-05-28 Gary V. Vaughan <gary@gnu.org>
7348 * m4/hash.c (m4_hash_resize): New function.
7349 * m4/hash.h: Add prototype.
7350 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
7351 benchmarking to find a good value for, say, autoconf. This is
7352 already a little quicker than before for me.
7354 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
7355 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
7356 and reenamed.
7357 * m4/hash.h: Adjust prototypes.
7359 2002-01-22 Akim Demaille <akim@epita.fr>
7361 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
7362 APIVERSION scheme.
7363 * tests/Makefile.am (package.m4): New.
7364 * tests/atlocal.in: Adjust to CVS Autotest.
7365 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
7366 * configure.ac: LIBOBJ is a forbidden string.
7367 Simplify AM_INIT_AUTOMAKE invocation.
7368 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
7369 options.m4.
7371 2002-01-21 gettextize <bug-gnu-utils@gnu.org>
7373 * po/Makefile.in.in: Upgrade to gettext-0.10.40.
7375 2001-10-19 Akim Demaille <akim@epita.fr>
7377 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
7379 2001-10-19 Akim Demaille <akim@epita.fr>
7381 * m4/input.c (m4_next_token): Display where was opened what is
7382 not closed.
7384 2001-10-19 Akim Demaille <akim@epita.fr>
7386 * m4/macro.c (expand_argument): Display where was opened what is
7387 not closed.
7389 2001-10-18 Akim Demaille <akim@epita.fr>
7391 * m4/input.c, modules/m4.c: Formatting changes.
7393 2001-10-17 Gary V. Vaughan <gary@gnu.org>
7395 * bootstrap: s/configure.in/configure.ac/
7397 2001-10-16 Gary V. Vaughan <gary@gnu.org>
7399 * m4/symtab.c (m4_symbol_destroy): This function calls
7400 m4_symbol_popdef, which recycles a symbols memory when the last
7401 definition is popped. Since we were passing the address of the
7402 symbol name found in the symbol table, and it was being removed
7403 partway through m4_symbol_destroy() we were referencing freed
7404 memory for the balance of the function. Now we take a copy of the
7405 symbol name tring and use that as a key into the symbol
7406 table... that way if the original symbol name is freed, the copy
7407 is still valid.
7409 2001-10-13 Akim Demaille <akim@epita.fr>
7411 * m4/ltdl.c: Update.
7413 2001-10-13 Akim Demaille <akim@epita.fr>
7415 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
7416 Don't gettextize internal error messages.
7418 2001-10-13 Akim Demaille <akim@epita.fr>
7420 * tests/macros.at (Arity and defn): New failing test.
7421 (Arity, defn, and freeze): New.
7423 Fix `Arity and defn'.
7425 * m4/input.c (m4_push_macro): Don't forget the arity.
7426 * modules/m4.c (defn): Likewise.
7428 2001-10-13 Akim Demaille <akim@epita.fr>
7430 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
7431 to...
7432 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
7433 (Propagation of traceon, Propagation of --trace): this new file.
7435 2001-10-13 Akim Demaille <akim@epita.fr>
7437 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
7438 interface instead of (name, argc...).
7439 Upon failure, specify which argument was guilty.
7440 Adjust callers.
7442 2001-10-13 Akim Demaille <akim@epita.fr>
7444 * modules/evalparse.c: Save translators' time: don't translate
7445 internal error messages.
7446 (m4_evaluate): Simplify/normalize error messages.
7447 * doc/m4.texinfo (Eval): Adjust.
7449 2001-10-13 Akim Demaille <akim@epita.fr>
7451 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
7452 where no checking is needed.
7453 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
7454 interface instead of (name, argc...).
7455 Adjust callers.
7456 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
7457 elsewhere.
7459 2001-10-13 Akim Demaille <akim@epita.fr>
7461 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
7462 exclude the builtin name from the count.
7463 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
7464 calling ifelse with a single argument is valid.
7465 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
7466 with 1 and 2 args, mostly to strengthen the test suite.
7468 2001-10-13 Akim Demaille <akim@epita.fr>
7470 * m4/output.c (m4_make_diversion, m4_insert_file)
7471 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
7473 2001-10-12 Gary V. Vaughan <gary@gnu.org>
7475 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
7476 since we call these things builtins in the rest of the code!
7478 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
7480 2001-10-12 Gary V. Vaughan <gary@gnu.org>
7482 Rather than forcing each builtin definition to manage its own
7483 argument range checking, tabulate the maxima and minima for all
7484 builtins in each module. This forces us to consider what the
7485 valid ranges for each builtin should be, and moves the checking
7486 code out of each builtin implementation and into the builtin
7487 caller infrastructure.
7489 * m4/m4module.h (struct m4_builtin): Add argument minima and
7490 maxima.
7491 * m4/m4private.h (struct m4_token): Reflect them here too.
7492 * m4/input.c (struct input_block): ...and here.
7493 (m4_token_copy): New function for token copying.
7494 (init_macro_token): Copy them from a token to the input stack.
7495 (m4_next_token): Don't forget to initialise them for text
7496 macros.
7497 * m4/macro.c (expand_argument): Use m4_token_copy, and also
7498 check argument counts before calling the builtin handler.
7499 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
7500 (m4_symbol_macro): Likewise.
7501 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
7502 parameters. Updated all callers.
7503 (m4_builtin_define): Ditto.
7504 (m4_macro_pushdef, m4_macro_define): Ditto.
7505 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
7506 * modules/evalparse.c: Declare argument counts for defined
7507 builtins and remove explicit calls to m4_bad_argc().
7508 * modules/gnu.c: Ditto.
7509 * modules/load.c: Ditto.
7510 * modules/m4.c: Ditto.
7511 * modules/modtest.c: Ditto.
7512 * modules/mpeval.c: Ditto.
7513 * modules/perl.c: Ditto.
7514 * modules/shadow.c: Ditto.
7515 * modules/stdlib.c: Ditto.
7516 * modules/time.c: Ditto.
7517 * TODO: Updated.
7519 2001-10-10 Gary V. Vaughan <gary@gnu.org>
7521 The trace semantics now attach the trace bit to a symbol name.
7522 For as long as a traceon(`foo') is active, calls to foo will be
7523 traced regardless of intervening undefines or module unloads.
7524 Fixed the flag propogation issues differently to the fixes
7525 reverted with the last attempt at nailing down trace:
7527 * m4/m4private.h: This file is not visible outside of the m4
7528 source tree, so I removed all the `M4_' and `m4_' prefixes to save
7529 on typing. Updated all clients.
7530 (m4_token): New typedef contains the fields that need to be passed
7531 around with the low level tokeniser.
7532 (m4_token_data): Removed.
7533 (m4_symbol): Now contains the traced flag again.
7534 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
7535 the trace bit set. This change is contained entirely within this
7536 module and doesn't leak out into the callers. Updated all
7537 clients.
7538 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
7539 new fields in m4_token. Updated all clients.
7540 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
7541 that `groks_macro_args' and `blind_if_no_args' flags are retained
7542 when defn() results are passed around in m4 code. Updated all
7543 callers.
7544 (m4_builtin_define): Ditto.
7545 (m4_macro_pushdef, m4_macro_define): Ditto.
7546 * m4/input.c (struct input_block): Add a flags field to facilitate
7547 the above.
7548 (m4_push_macro): ...use it.
7549 (init_macro_token): Retrieve it.
7550 (m4_next_token): Initialise it.
7551 * m4/macro.c (expand_argument): Copy it.
7552 * m4/m4module.h: Adjust.
7553 * tests/builtins.at: Adjust the expected output of the trace
7554 tests to reflect the change in semantics.
7555 * tests/modules.at (modules: trace): Check that unloading a
7556 module which supplies a traced symbol definition doesn't lose te
7557 trace bit.
7559 2001-10-07 Gary V. Vaughan <gary@gnu.org>
7561 * modules/gnu.c (m4_macro_table): Display the timetamp when
7562 expanding __m4_version__.
7564 * configure.ac (--with-modules): Forgot a comma in the
7565 AC_HELP_STRING parameter list.
7567 2001-10-05 Gary V. Vaughan <gary@gnu.org>
7569 * bootstrap: Remove aclocal.m4t when it is no longer required.
7571 2001-10-05 Akim Demaille <akim@epita.fr>
7573 * tests/Makefile.am: Adjust for gnuprog2.
7574 * tests/m4.in: There can be a leading path.
7575 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
7576 * tests/testsuite.at: Adjust to the most recent Autotest.
7577 (AT_CHECK_M4_FILTER): Fix and rename as...
7578 (AT_TEST_M4): this.
7579 * tests/others.at: Use it.
7581 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
7582 variable in shell scripts, one uses `$'...
7584 2001-10-04 Gary V. Vaughan <gary@gnu.org>
7586 * configure.ac: `rm -f $m4_getopt_h' was lost.
7588 2001-10-04 Gary V. Vaughan <gary@gnu.org>
7590 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
7591 time. Define it for config.h in order to...
7592 * src/main.c (main): ...display the timestamp for --version.
7594 2001-10-04 Akim Demaille <akim@epita.fr>
7596 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
7597 previous builtins `regexp' and `patsubst'.
7598 (regexp, patsubst): Use them.
7599 (eregexp, epatsubst): New builtins.
7600 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
7601 (Epatsubst and Patsubst, Eregexp and Regexp): these.
7602 (Extensions): More info on REs.
7604 2001-10-04 Akim Demaille <akim@epita.fr>
7606 * modules/modtest.c (init_handler): Consistently output to stderr.
7607 (finish_handler): New.
7608 (test): The `if' is an `assert'.
7609 * tests/modules.at: Adjust.
7611 2001-10-04 Akim Demaille <akim@epita.fr>
7613 * m4/utility.c (m4_bad_argc): Detail the mismatches.
7615 2001-10-01 Akim Demaille <akim@epita.fr>
7617 * tests/generate.awk: Tag the tests with `documentation'.
7618 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
7619 Use the make the existing modtest tests more uniform, and complete
7620 the set of possibilities.
7622 2001-10-01 Akim Demaille <akim@epita.fr>
7624 * config/gmp.m4: Consult the user before using GMP: use
7625 --without-gmp.
7626 * configure.ac: Adjust.
7627 * modules/gmp.c: No protection needed as the module is not built
7628 if GMP is not used.
7630 2001-10-01 Akim Demaille <akim@epita.fr>
7632 * tests/generate.awk: Remove debugging code.
7633 (fatal): Specify the current location.
7635 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
7636 * modules/gnu.c, modules/m4.c: Use M4ARG.
7638 2001-10-01 Akim Demaille <akim@epita.fr>
7640 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
7641 (m4_regexp_compile): New.
7642 (regexp, patsubst): Use it.
7644 2001-09-30 Gary V. Vaughan <gary@gnu.org>
7646 Reinstate the memory handling improvements from the patch I just
7647 reverted. Relevant ChangeLog entries repeated here:
7649 * m4/module.c (m4_module_remove): New function that holds the core
7650 of the old m4_module_unload.
7651 (m4_module_unload): Use it.
7652 (m4_module_unload_all): When we know the modules will never be
7653 used again (i.e. on exit), free up as much module memory as
7654 possible. There are still some artifacts from resident modules
7655 living inside ltdl.c, but everything else is freed.
7656 * m4/debug.c (m4_debug_exit): Free memory allocated in
7657 m4_debug_init().
7658 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
7659 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
7660 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
7661 * m4/m4module.h: Updated prototypes.
7662 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
7663 * m4/hash.h: Updated prototypes.
7664 * src/main.c (main): Use all these new functions to clean up as
7665 much memory as possible before exit.
7667 2001-09-30 Gary V. Vaughan <gary@gnu.org>
7669 Reverted my large patch for removing the old m4_symbol
7670 structure on 2001-09-20. We are still not happy about the way
7671 trace works in conjunction with defn and undefine, and leaving
7672 the reverted patch active prevents us from moving the traced
7673 bit from the definition back to the symbol.
7675 2001-09-30 Gary V. Vaughan <gary@gnu.org>
7677 * configure.in: Moved to...
7678 * configure.ac: ...here. Added a libtool like timestamped
7679 banner, and tidied up the libltdl cruft.
7680 * config/mkstamp: Script to extract a timestamp from ChangeLog.
7681 * modules/Makefile.am (INCLTDL): Removed. This is required
7682 only when libltdl is configured in a subdirectory.
7683 * src/Makefile.am: Ditto.
7684 (LIBADD_DL): No need to add this again, libtool already knows
7685 that libm4.la depends on it.
7686 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
7687 them.
7689 * TODO: stackovf.c is basically broken.
7690 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
7692 2001-09-28 Akim Demaille <akim@epita.fr>
7694 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
7696 2001-09-27 Akim Demaille <akim@epita.fr>
7698 * tests/m4.in: Don't use short options.
7699 Simplify the stderr signature normalization.
7701 2001-09-27 Akim Demaille <akim@epita.fr>
7703 tests/m4 shall be position independent.
7705 * tests/m4.in: New.
7706 * tests/m4: Remove.
7707 * tests/testsuite.at: No args to AT_INIT.
7708 * configure.in, tests/Makefile.am: Adjust.
7710 2001-09-22 Akim Demaille <akim@epita.fr>
7712 Autotest has changed again.
7714 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
7715 (package.m4): Remove.
7716 * configure.in: Adjust to LIBADD_GMP.
7718 2001-09-21 Gary V. Vaughan <gary@gnu.org>
7720 * config/gmp.m4 (AC_ARG_WITH): Removed.
7721 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
7722 (AC_LIB_GMP): When performing a test compile against libgmp,
7723 include the header gmp.h if possible, and link against -lgmp. If
7724 they both work define USE_GMP.
7725 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
7726 (mpeval_LTX_init_func): Complain on load that there was no libgmp
7727 at compile time.
7729 2001-09-20 Gary V. Vaughan <gary@gnu.org>
7731 * m4/evalparse.c: Moved to...
7732 * modules/evalparse.c: ...here. This code is shared between
7733 modules/mpeval.c and modules/m4.c, so there is no need to pollute
7734 the libm4 API with its details. Moderately rewritten to interface
7735 into its clients more simply.
7736 * m4/eval.c: Deleted. Migrated functionality to...
7737 * modules/m4.c: ...here.
7738 (builtin_eval): Implemented in terms of the new interface style.
7739 * modules/mpeval.c (builtin_mpeval): Ditto.
7740 * m4/m4module.h: Removed references to the former m4/eval.c.
7741 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
7742 (EXTRA_libm4_la_SOURCES): Deleted.
7743 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
7744 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
7746 2001-09-20 Akim Demaille <akim@epita.fr>
7748 * config/gmp.m4 (AM_WITH_GMP): Rename as...
7749 (AC_LIB_GMP): this.
7750 By default, use gmp.
7751 Massive revamping.
7752 * configure.in: Adjust.
7753 Use Automake conditionals for USE_GMP.
7754 Always compute sizeof (long long int).
7755 This was a bug BTW, as `eval' (not `mpeval') depends on it:
7756 before, it was used _only_ if mpeval was not activated.
7757 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
7758 (mpeval_la_LIBADD): New macros.
7759 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
7760 Indent.
7761 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
7762 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
7763 WITH_GMP.
7765 2001-09-20 Akim Demaille <akim@epita.fr>
7767 * tests/Makefile.am (package.m4): New.
7768 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
7770 2001-09-20 Gary V. Vaughan <gary@gnu.org>
7772 More cleanup. After the last patch, m4_symbol holds nothing but
7773 the head of a chain of m4_token_data. So I have removed the old
7774 m4_symbol, so that m4_token_data chains are stored directly in the
7775 value cell of a hash table node. But there's more... m4_symbol
7776 was a more natural name for the symbol value cell, and now that it
7777 is gone I have renamed the former m4_token_data structure to
7778 m4_symbol. This change turned out to be a pig to get right, since
7779 the original code didn't need to modify the value cell itself,
7780 since changing the chain happened inside the m4_symbol that used
7781 to be returned -- I had to pass the address of the value cell
7782 across various function calls, incase the head value changed. I
7783 also tightened up the memory management to help me find a nasty
7784 memory corruption bug that took me all night to track down...
7786 * m4/m4private.h (struct m4_symbol): Removed.
7787 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
7788 all references.
7789 * m4/hash.c (m4_hash_iterator_value): Return the address of the
7790 value cell. Updated all callers.
7791 * m4/symtab.c: Took advantage of the simplification in the data
7792 structures to rewrite a lot of this file more simply. There is
7793 still some room for optimisation here, but we should tackle that
7794 systematically closer to the release.
7796 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
7797 revealed. This version is ahead of CVS libtool until I get chance
7798 to flush my changes.
7799 * m4/module.c (m4_module_remove): New function that holds the core
7800 of the old m4_module_unload.
7801 (m4_module_unload): Use it.
7802 (m4_module_unload_all): When we know the modules will never be
7803 used again (i.e. on exit), free up as much module memory as
7804 possible. There are still some artifacts from resident modules
7805 living inside ltdl.c, but everything else is freed.
7806 * m4/debug.c (m4_debug_exit): Free memory allocated in
7807 m4_debug_init().
7808 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
7809 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
7810 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
7811 * m4/m4module.h: Updated prototypes.
7812 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
7813 * m4/hash.h: Updated prototypes.
7814 * src/main.c (main): Use all these new functions to clean up as
7815 much memory as possible before exit.
7817 2001-09-18 Gary V. Vaughan <gary@gnu.org>
7819 The `traced' flag needs to be attached to the definition of a
7820 symbol rather than the current symbol containing the definition.
7821 Implementing this showed up some long standing post 1.4 bugs in
7822 flag propogation which I also fixed.
7824 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
7825 (struct m4_token_data): And add it back in here.
7826 * m4/input.c (init_macro_token): Propogate the traced flag
7827 correctly.
7828 * m4/macro.c (expand_argument): Ditto.
7829 * tests/builtins.at (trace2, trace3): New tests based on Akim's
7830 sadistic email ;-)
7832 2001-09-08 Gary V. Vaughan <gary@gnu.org>
7834 * m4/m4private.h (struct m4_token_data): Simplified by removing
7835 the redundant `traced' flag, and one level of structure nesting.
7836 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
7837 * m4/input.c (init_macro_token): No need to initialise removed
7838 `traced' field.
7839 * m4/macro.c (expand_argument): No need to copy it either.
7840 * m4/utility.c (m4_token_data_func_traced): Or provide an access
7841 function.
7843 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
7844 dependant on multiple symbols with the same key, so preserving
7845 relative symbol order in each bucket during resizing is no longer
7846 required. The resize function is considerably faster as a result.
7848 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
7849 s/m4_symbol_insert/m4_symbol_define/g;
7850 s/m4_builtin_insert/m4_builtin_define/g;
7851 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
7853 2001-09-08 Gary V. Vaughan <gary@gnu.org>
7855 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
7856 commits, the m4_lookup_symbol dispatch function is split into
7857 specialised functions that must be called directly.
7859 * m4/m4module.h (m4_symbol_lookup_t): Removed.
7860 * m4/symtab.c (m4_lookup_symbol): Removed.
7861 (m4_symbol_builtin, m4_symbol_macro): New functions.
7862 * m4/builtin.c (m4_builtin_define): Split into...
7863 (m4_builtin_pushdef, m4_builtin_insert): ...these.
7864 (m4_macro_define): Split into...
7865 (m4_macro_pushdef, m4_macro_insert): ...these.
7866 * src/main.c (main): Set command line macros from `-D' parameters
7867 using `m4_macro_define'.
7869 2001-09-08 Gary V. Vaughan <gary@gnu.org>
7871 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
7872 this from m4_remove_table_reference_symbols().
7873 * m4/m4module.h, m4/module.c: Updated all references.
7875 2001-09-07 Akim Demaille <akim@epita.fr>
7877 * modules/stdlib.c, modules/times.c: Misc cleanups.
7879 2001-09-07 Akim Demaille <akim@epita.fr>
7881 * configure.in: We now need Autoconf 2.52e.
7882 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
7883 and `M4_SYMBOL_DELETE'.
7884 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
7885 * src/main.c (main): Adjust.
7887 2001-09-06 Gary V. Vaughan <gary@gnu.org>
7889 Fix the obstack.h problem once and for all! At configure time we
7890 can test for a system supplied obstack.h: depending on the
7891 result, we now generate system.h with an #include of the correct
7892 header. As a bonus, I've also added a --with-included-obstack,
7893 incase the user doesn't like the system obstack for some
7894 reason... and also we can test the shipped obstack on a system
7895 that has oe of its own. We also now need to be careful to add
7896 build directories to the include search path, since the generated
7897 system.h will be in the build tree.
7899 * configure.in (AC_CONFIG_FILES): Generate system.h from
7900 system-h.in.
7901 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
7902 include the system obstack header or the copy shipped with M4.
7903 Allow the user to override configure and force the build to use
7904 the shipped version.
7905 * m4/system-h.in: New file, template for...
7906 * m4/system.h: ...this. Now deleted.
7907 * m4/m4module.h: Include system.h before everything else.
7908 * src/freeze.c: Ditto.

7923 2001-09-05 Akim Demaille <akim@epita.fr>
7925 * modules/format.c (format): Have a bigger `str'.
7927 2001-09-05 Akim Demaille <akim@epita.fr>
7929 Rationalize warnings, reporting the macro name as if it were a
7930 program name, and assertions.
7932 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
7933 (M4WARN): New.
7934 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
7935 (m4_symbol_delete):
7936 Use assert for internal errors.
7937 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
7938 M4WARN.
7939 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
7940 M4WARN and assert.
7941 * tests/builtins.at (pushpop): Adjust.
7943 2001-09-05 Akim Demaille <akim@epita.fr>
7945 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
7946 with pointers.
7948 2001-09-05 Akim Demaille <akim@epita.fr>
7950 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
7951 * m4/macro.c, m4/symtab.c: Adjust.
7953 2001-09-05 Akim Demaille <akim@epita.fr>
7955 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...

7957 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
7958 (m4_symbol_popdef, m4_symbol_delete): New.
7959 (m4_lookup_symbol): Adjust.
7960 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
7962 2001-09-05 Akim Demaille <akim@epita.fr>
7964 * m4/m4module.h (m4_symbol_lookup): Rename as...
7965 (m4_symbol_lookup_t): this.
7967 2001-09-05 Akim Demaille <akim@epita.fr>
7969 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
7970 unused.
7971 * m4/symtab.c (m4_lookup_symbol): Adjust.
7973 2001-09-03 Gary V. Vaughan <gary@gnu.org>
7975 Bootstrap will now work with Libtool 1.4.1 or higher:
7976 * bootstrap: Remove stale autom4te.cache files when
7977 rebootstrapping.
7978 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
7979 libtool.m4.
7980 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
7981 libtool.m4 directly.
7982 Run libtoolize to refresh ltmain.sh.
7983 * config/ltmain.sh: Deleted.
7984 * acinclude.m4: Deleted.
7985 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.

7988 implementation for the cvs impaired libtool user.
7990 2001-09-03 Akim Demaille <akim@epita.fr>
7992 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
7993 internal errors.
7994 Avoid using `default' in switch, as it hides useful compiler
7995 warnings when a case is forgotten.
7997 2001-09-03 Akim Demaille <akim@epita.fr>
7999 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
8000 is no such thing as `WITH_MODULES'.
8002 2001-09-03 Akim Demaille <akim@epita.fr>
8004 Improve the test suite's selfcontainedness.
8006 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
8007 (Include, Undivert): Tag the other input files.
8008 * tests/generate.awk: Catch `@comment file:'.
8009 `-I $src' is no longer needed.
8010 `next' is really like `return': the rest is skipped.
8011 Adjust to `input.m4'.
8012 (fatal): New function.
8013 * tests/foo, tests/incl.m4: Remove.
8015 2001-09-01 Gary V. Vaughan <gary@gnu.org>
8017 The shadowing mechanism and, infact, the whole symbol table
8018 implementation was creaking under the weight of the features piled
8019 on top of it. We now have a separate hash table module which will
8020 dynamically resize to keep symbol density withing good performace
8021 limits, and a new symtab module layered above it. Symbol lookups
8022 are now marginally more efficient (since the shadowed flag is no
8023 longer required) and symbol removal, such as on module unload, is
8024 considerably faster due to a reorganisation of the data structures
8025 used in symtab.c.
8027 * src/main.c (main): Don't mention `-H'.
8028 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
8029 effect.
8030 * NEWS: Updated.
8031 * m4/hash.c: New generalised dynamic hash table data structure
8032 management module.
8033 * m4/hash.h: Public interface.
8034 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
8035 (libm4_la_SOURCES): Add hash.c.
8036 * m4/symtab.c: More or less rewritten from scratch, within the
8037 bounds of the previous API.
8038 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
8039 call. Updated all callers.
8040 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
8041 declarations to reflect API changes.
8042 (M4INIT): Generate a declaration too, to avoid the warning with
8043 --enable-debug builds.
8044 (M4FINISH): Ditto.
8045 (HASHMAX): Removed.
8046 * m4/utility.c (hash_table_size): Removed.
8047 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
8048 names, which are then looked up by builtin_dumpdef() as necessary.
8049 This implies a small speedup in builtin_symbols(), which discarded
8050 all of the symbol info under the old call.
8051 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
8052 shadowing is implicit in respect to the new data structures.
8053 symbol names are no longer duplicated here, they are stored in the
8054 key field of the hash table.
8055 Moved macro_args and blind_no_args...
8056 (m4_token_data): ...to here.
8057 m4/macro.c (expand_macro): Added a name argument since the symbol
8058 name is no longer copied into each struct m4_symbol. Modified all
8059 callers.
8060 (collect_arguments): Ditto.
8061 * modules/m4.c (set_trace): Ditto.
8062 * modules/gnu.c (builtin_symbols): Updated.
8063 * src/freeze.c (produce_symbol_dump): Much improved in light of
8064 the improved symbol table layout.
8066 2001-09-01 Gary V. Vaughan <gary@gnu.org>
8068 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
8069 to M4_SYMBOL_NEXT.
8070 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
8071 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
8072 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
8073 SYMBOL_HANDLE): Ditto.
8074 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
8075 modules/gnu.c, modules/m4.c, src/freeze.c,
8076 src/main.c: Updated all references.
8078 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
8079 Automake 1.5 chokes on dynamic source file lists, Besides, it is
8080 already listed in m4_LDADD... how did that ever used to work?
8081 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
8082 link.
8083 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
8084 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
8086 * tests/m4: Don't call the m4 wrapper script with libtool, it
8087 works fine all by itself.
8089 2001-08-30 Gary V. Vaughan <gary@gnu.org>
8091 The experimental `changeword' feature never took off, and has
8092 no obvious advantages over `changesyntax' to compensate the
8093 enormous speed penalty it carries:
8094 * configure.in (ENABLE_CHANGEWORD): Removed.
8095 * m4/m4module.h (m4_set_word_regexp): Removed.
8096 * m4/m4private.h (m4_token_data): Removed original_text field.
8097 * m4/utility.c (m4_token_data_orig_text): Removed.
8098 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
8099 * m4/macro.c: Ditto.
8100 * src/main.c: Ditto.
8101 * modules/Makefile.am (changeword.la): Removed.
8102 * modules/changeword.c: File removed.
8103 * doc/m4.texinfo: References to changeword and --word-regexp
8104 removed.
8105 * po/POTFILES.in: modules/changeword.c removed.
8106 * tests/atlocal.in (ENABLE_CHANGEWORD): Removed.
8107 * tests/builtins.at (changeword): Test removed.
8109 2001-08-30 Akim Demaille <akim@epita.fr>
8111 * bootstrap.sh: Create aclocal.m4 instead of modifying it.
8112 This also help having a single list of m4 files: in
8113 config/Makefile.am.
8114 * config/Makefile.am (STANDARD_MACROS): Rename as...
8115 (ACLOCAL_MACROS): this.
8116 (list-standard-macros): Remove.
8117 (spy): New.
8119 2001-08-29 Gary V. Vaughan <gary@gnu.org>
8121 In an attempt to moderate my egomania...
8122 * tests/modules.at: Remove attributions.
8124 * tests/generate.awk: When making substitutions to "@&t@", either
8125 "&" or "\&" in the substitution string argument to gsub refer back
8126 to the matched text. "@\\&t@" seems to work though, Tests 43 and
8127 67 now pass for me.
8129 2001-08-29 Akim Demaille <akim@epita.fr>
8131 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)
8132 (include, indir, multiquotes, patsubst, pushdef/popdef, regexp)
8133 (sync-lines, trace, translit, undivert, wrap): Move to...
8134 * tests/builtins.at: this new file.
8135 * tests/others.at (Discard comments, import-environment): Move to...
8136 * tests/options.at: this new file.
8138 2001-08-29 Akim Demaille <akim@epita.fr>
8140 * tests/others.at (Freezing modules)
8141 (--module-directory: absolute path, modpath2, modpath3)
8142 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
8143 * tests/modules.at: here, new file.
8144 * tests/others.at, tests/generate.awk: Add a banner.
8145 * tests/testsuite.at: Adjust.
8146 (AT_CHECK_M4_FILTER): New, but unused.
8148 2001-08-29 Akim Demaille <akim@epita.fr>
8150 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
8151 handle that.
8152 * tests/others.at (wrap): Inline wrap.m4.
8153 (shadow): Inline shadow.m4.
8154 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
8155 * tests/m4: Simplify.
8157 2001-08-29 Akim Demaille <akim@epita.fr>
8159 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
8160 --language.
8162 2001-08-29 Akim Demaille <akim@epita.fr>
8164 * tests/generate.awk (normalize): s/@__@/@&t@/.
8166 2001-08-28 Akim Demaille <akim@epita.fr>
8168 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.
8170 2001-08-28 Gary V. Vaughan <gary@gnu.org>
8172 * bootstrap (generate.awk): Generate test cases with new script.
8174 2001-08-27 Akim Demaille <akim@epita.fr>
8176 * tests/Makefile.am (installcheck-local): Don't use
8177 `dc_install_base' which is not visible here, but `exec_prefix'
8178 which is clearly the RT anyway.
8179 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
8180 related to testing a now installed m4.
8181 * tests/m4: Do it here.
8183 2001-08-27 Akim Demaille <akim@epita.fr>
8185 * tests/others.at (indir): Formatting change.
8187 2001-08-27 Akim Demaille <akim@epita.fr>
8189 * tests/Makefile.am (installcheck-local): New.
8190 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
8191 the test suite.
8192 Prefer options over envvars.
8193 * src/main.c (main): First bug caught by the test suite (yeah!):
8194 --batch lacked a `break' which resulted in an accidental
8195 invocation of --discard-comments.
8197 2001-08-27 Akim Demaille <akim@epita.fr>
8199 * tests/others.at (capitalize, changeword, comments, ddivert)
8200 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
8201 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
8202 (sysv-args, trace, translit, undivert): Don't rely on files in
8203 examples/: AT_DATA them.
8205 2001-08-27 Akim Demaille <akim@epita.fr>
8207 Let the test suite use a wrapper around the not installed m4 to
8208 pretend it is (installed).
8210 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
8211 such a way that m4 does not process them.
8212 * configure.in: The package name seems to be `m4', not `M4'.
8213 * tests/m4: New.
8214 * tests/atlocal.in (at_package, M4): Remove.
8215 * tests/testsuite.at, tests/others.at: Use m4, not $M4.
8217 2001-08-27 Akim Demaille <akim@epita.fr>
8219 * tests/Makefile.am (CLEANFILES): Remove.
8220 (DISTCLEANFILES, clean-local): New.
8221 * examples/mktests.sh: Remove.
8223 2001-08-27 Akim Demaille <akim@epita.fr>
8225 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
8226 Don't use aclocal: it's written by hand.
8227 * aclocal.m4: m4_include all the files instead of being built by
8228 aclocal.
8229 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
8230 until it reads the traces by itself.
8231 * configure.in: Require Autoconf 2.42c as we are now using
8232 AC_CONFIG_TESTDIR instead of AT_CONFIG.
8233 Catch unexpanded `jm_' macros.
8234 * config/atconfig.m4: Remove.
8235 * config/error.m4: new.
8236 * config/Makefile.am: Ship the files included by aclocal.m4.
8237 * tests/Makefile.am (TESTSUITE_SOURCES): Rename as...
8238 (TESTSUITE_AT): this, to please Automake.
8239 (TESTSUITE): This target uses autotest/autotest.m4, not
8240 autotest/general.m4.
8241 * tests/testsuite.at: Prereq Autotest 2.52c.
8242 * examples/Makefile.am (pkgdata_DATA): Rename as...
8243 (dist_pkgdata_DATA): this.
8244 * doc/Makefile.am (man_MANS): Rename as...
8245 (dist_man_mans): this.
8247 2001-08-20 Gary V. Vaughan <gary@gnu.org>
8249 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
8250 Robert Collins, building on Cygwin no longer requires Windows
8251 import and export symbol decorations.
8252 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.
8253 * m4/error.h (M4_SCOPE) [cygwin*]: Ditto.
8254 * m4/debug.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
8255 * m4/error.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.

8260 * m4/xmalloc.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
8261 * configure.in (LIBM4_DLL_IMPORT) [cygwin*]: Don't set this
8262 anymore.
8263 * src/Makefile.am (AM_CPPFLAGS) [cygwin*]: Don't use it either!
8264 * modules/Makefile.am (AM_CPPFLAGS) [cygwin*]: Ditto.
8266 2001-08-20 Gary V. Vaughan <gary@gnu.org>
8268 Ansify the source. Previously we had a mix, where my code was
8269 in a K&R compatible style, and the preexisting code was in ANSI
8270 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
8271 and now the code base is much cleaner.
8273 * m4/system.h: Remove M4_PARAMS macro and all users. Remove
8274 VOID macro and all users.
8275 * m4/m4module.h: Ansify function prototypes and headers.
8276 * m4/builtin.c: Ditto.
8277 * m4/evalparse.c: Ditto.
8278 * m4/input.c: Ditto.
8279 * m4/macro.c: Ditto.
8280 * m4/module.c: Ditto.
8281 * m4/output.c: Ditto.
8282 * m4/path.c: Ditto.
8283 * m4/symtab.c: Ditto.
8284 * m4/utility.c: Ditto.
8285 * modules/format.c: Ditto.
8286 * modules/gnu.c: Ditto.
8287 * modules/m4.c: Ditto.
8288 * modules/mpeval.c: Ditto.
8289 * src/freeze.c: Ditto.
8290 * src/m4.h: Ditto.
8291 * src/main.c: Ditto.
8293 2001-08-20 Akim Demaille <akim@epita.fr>
8295 * config/atconfig.m4: s/EOF/ATEOF/, so that configure can be
8296 generated with stock 2.52.
8298 2001-08-20 Akim Demaille <akim@epita.fr>
8300 * config/atconfig.m4: New, until part of Autoconf per se.
8301 * configure.in (AT_CONFIG): Use it.
8302 Adjust.
8303 * tests/mkconfig.sh, tests/atconfig.in, tests/defs: Remove.
8304 * tests/atlocal.in: New.
8305 * tests/generate.awk: For the time being, the empty quadrigraph is
8306 `@__@'.
8307 * tests/others.at (changeword, gmp): Check the configuration
8308 variable against `yes'.
8309 * tests/testsuite.at (dnl): Allow it, as it's used all over the
8310 place.
8312 2001-08-20 Akim Demaille <akim@epita.fr>
8314 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
8315 * modules/m4.c (undivert): Disable the possibility of undiverting
8316 several files at once: it is not documented, it is inconsistent
8317 with the other macros, it can be straightforwardly mocked by
8318 several invocations, and most importantly, it prevents the
8319 possibility of other kinds of extension.
8320 Use `m4_numeric_arg'.
8322 2001-08-20 Akim Demaille <akim@epita.fr>
8324 * examples/include.m4: Typo.
8325 * tests/generate.awk: Really add it.
8326 * tests/Makefile.am: Adjust.
8327 * tests/others.at (Discard comments): It sure fails without `-c'.
8328 (include, undivert): Add -I examples/.
8330 2001-08-20 Akim Demaille <akim@epita.fr>
8332 Use sprintf, not ecft and friends since it is standard, portable,
8333 simplifies the code, and since the latter is even deprecated
8334 according to the GNU libc documentation.
8336 * modules/format.c: Drop evct support.
8338 2001-08-19 Gary V. Vaughan <gary@gnu.org>
8340 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Cleaned up. Don't test
8341 for `-pipe' here...
8342 * configure.in: ...do it here instead.
8344 * c-boxes.el: Deleted.
8345 * m4/builtin.c: Reformat box comments to be closer to GNU
8346 standards.
8347 * m4/debug.c: Ditto.
8348 * m4/eval.c: Ditto.
8349 * m4/evalparse.c: Ditto.

8357 * modules/format.c: Ditto.
8358 * modules/gnu.c: Ditto.
8359 * modules/load.c: Ditto.
8360 * modules/m4.c: Ditto.
8361 * modules/modtest.c: Ditto.

8391 (generate.at): Install a temporary hack until the actual
8392 generate.awk is added to the repository.
8393 * tests/atconfig.in: New.

8442 others.at no longer depends on other-tests/.
8444 * tests/others.at (stackovf): You're actually...
8445 (sync-lines): this.
8446 (modfreeze, modpath1, modpath2, modpath3, modpath4, modtest, shadow)
8447 (unload.test): Keep their authorship.
8448 (discard-comments, gmp, import-environment, modfreeze)

8463 2001-08-17 Akim Demaille <akim@epita.fr>

8467 * examples/patsubst.m4, modules/modtest.m4, modules/shadow.m4,
8468 * examples/reverse.m4, tests/other-tests/import-environment.m4,
8469 * tests/other-tests/iso8859.m4: Don't produce trailing blanks.

8480 2001-08-17 Akim Demaille <akim@epita.fr>
8482 Drop Autoconf 2.13 compatibility.
8484 * configure.in (changeword): No need to undefine it, as anyway if
8485 it's defined, M4sugar moved it as m4_changeword.
8486 And anyway, proper quotation is enough.
8487 (m4_pattern_allow): As it exists in 2.50, just use it.
8488 (AC_OUTPUT): Split in AC_CONFIG_FILES and AC_CONFIG_COMMANDS.
8489 Don't handle Gettext's duties, let it handle them.

8501 (MAINTAINERCLEANFILES): Remove texinfo.tex and mdate-sh which are
8502 in `config/' now.

8522 2001-08-16 Gary V. Vaughan <gary@gnu.org>

8527 * m4/ltdl.c: Updated from master copy.
8528 * m4/module.c: Reimplemented to take advantage of advances in

8536 m4/module.h: Prototype new module management API.
8537 (m4_modules): No longer required.
8538 (m4_module_init_t, m4_module_finish_t): POSIX namespace
8539 violations, renamed to...
8540 (m4_module_init_func, m4_module_finish_func): ...these,
8541 respectively.
8542 (M4INIT_HANDLER): Clean way to declare init functions in modules.
8543 (M4FINISH_HANDLER): And similarly for finish functions.
8544 * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER
8545 -- Add indirection to the CONC macro so that arguments are
8546 correctly expanded.
8547 * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
8548 * modules/shadow.c (m4_init_module): Ditto.
8549 Due to new init function semantics, be careful to perform the
8550 initialisation only on first load.
8551 * modules/perl.c (m4_init_module): Ditto. And Ditto.
8552 (m4_finish_module): Replaced with M4FINISH_HANDLER.
8553 Due to new finish function semantics, be careful to perform the
8554 finalisation only on first load.
8555 * m4/m4private.h (m4_module): Removed in favour of...
8556 (m4_module_data): ...structure without all the wrapper fields.
8557 Instances of this new structure are stored associated lt_dlhandles
8558 with lt_dlcaller_data_set().
8559 * m4/builtin.c (m4_builtin_define): Takes a handle argument
8560 instead of the old module argument.
8561 (m4_builtin_table_install): Ditto.
8562 * modules/load.c (m4_resident_module): Removed. This is no
8563 longer implemented as a magic symbol...
8564 * modules/m4.c (m4_resident_module): Ditto.
8565 * modules/load.c (M4INIT_HANDLER): ...the module init function now
8566 uses the ltdl api to make the module resident.
8567 * modules/m4.c (M4INIT_HANDLER): Ditto.
8568 * modules/load.c (builtin_modules): Traverse the loaded module
8569 list with lt_dlhandle_next.
8570 (builtin_load): Much simplified in light of the reimplemented
8571 module loader.
8572 * src/freeze.c (produce_module_dump): Cleaned up and optimised in
8573 light of the m4/module.c rewrite.

8578 (libm4_la_SOURCES): Delete list.c reference.
8579 * m4/m4private.h (m4_token_data): Add a handle field. This
8580 eliminates many of the searches to find the handle associated with
8581 various tokens that are passed between functions.
8582 (struct m4_symbol): Removed the module field. The
8583 module association does not belong with the symbol...
8584 * m4/input.c (struct m4_builtin): ...it belongs with the builtin
8585 that the module implementation code is from. Added a handle
8586 field.
8587 (m4_push_macro): Add a `handle' argument. Changed all callers.
8588 (init_macro_token): Set the `handle' field for the
8589 m4_token_data.
8590 * m4/macro.c (expand_argument): Copy the new handle field during
8591 reassignment.

8593 optimise the search for the correct builtin structure, and pass
8594 the handle details to m4_builtin_define.
8596 2001-08-15 Akim Demaille <akim@epita.fr>
8598 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Be sure `m4/' exists
8599 when creating `m4/obstack.h'.
8600 * tests/Makefile.am (TESTS_ENVIRONMENT): Pass top_srcdir and
8601 top_builddir.
8602 * tests/defs: Make them absolute.
8603 (CDPATH) Neutralize.
8604 * tests/gethem: Use them.
8606 2001-08-14 Gary V. Vaughan <gary@gnu.org>
8608 * config/ltmain.sh: Doh! Import again for a quoting fix that
8609 prevented any regression test from passing.
8611 * m4/m4module.h (obstack.h): Choose between installed version
8612 and shipped version based on configure tests.
8613 * src/freeze.c (obstack.h): Ditto.
8615 * acconfig.h: Removed. No longer required.
8617 * bootstrap: Rewritten to play nicely with Autoconf 2.5x.
8618 * configure.in (MY_NAME, MY_VERSION): Define these once, and feed
8619 them to AC_INIT and AM_INIT_AUTOMAKE.
8620 * Makefile.am (AUTOMAKE_OPTIONS): Remove `gnits' which would
8621 disallow MY_NAME and MY_VERSION arguments to AM_INIT_AUTOMAKE.
8622 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Don't choke on
8623 shell variable m4_cv_func_obstack_h.
8624 * tests/defs (M4): Be more careful about relative path to libtool
8625 script and m4 binary by using $srcdir.
8627 * src/main.c (main): Use lt_dlinsertsearchdir to prepend -M
8628 optargs to the existing libltdl search path.
8629 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.
8630 * m4/ltdl.c: Updated.
8631 * m4/ltdl.h: Ditto.
8632 * config/ltmain.sh: Ditto.
8634 2001-08-11 Gary V. Vaughan <gary@gnu.org>
8636 * src/main.c (main): Add `-b' (for `batch') mode switch to force
8637 interactive mode off.
8639 2001-08-10 Akim Demaille <akim@epita.fr>
8641 * configure.in: Require Autoconf 2.52.
8642 (AC_ARG_PROGRAM): Remove, handled by Automake.
8643 (m4_getopt): Rename as...
8644 (m4_getopt_h): this.
8645 Allow the tokens `m4_cv_*', `m4_top_srcdir', and `m4_getopt_h'.
8646 Undefine `changeword' only if defined.
8647 * config/gnu-obstack.m4: Require Autoconf 2.52.
8648 (M4_AC_FUNC_OBSTACK): Rename `m4_obstack' and `m4_obstack_h'.
8649 Allow this token.
8651 2001-08-09 Yuji Minejima <ggb01164@nifty.ne.jp>
8653 * doc/m4.texinfo: Fix some typos, and apply some small
8654 clarifications.
8656 2001-08-09 Andreas Schwab <schwab@suse.de>
8658 * src/main.c (main): Fix improper uses of error (missing format
8659 string).
8661 2001-08-07 Akim Demaille <akim@epita.fr>
8663 Improve `make distcheck'.
8665 * configure.in: Be sure to be able to run `mkconfig.sh' when src
8666 != build.
8667 * Makefile.am (dist-hook): Remove, as it is no longer needed.
8668 * doc/m4.texinfo (Include): Add missing blank.
8669 * m4/Makefile.am (EXTRA_DIST): Distribute gnu-obstack.h and
8670 obstack.c.

8694 2001-04-08 Roderick Koehle <Roderick.Koehle@infineon.com>
8696 * modules/format.c (format): Formatting for %f was not
8697 interpreting the position of the decimal point correctly for
8698 whole numbers.
8700 2000-12-01 Gary V. Vaughan <gary@gnu.org>
8702 * TODO: Removed m4exit bug.
8703 * modules/load.c (m4_resident_module): Make this module resident.
8704 * module/m4.c (m4_resident_module): Ditto.
8705 * m4/modules.c (m4_module_load): Use new ltdl resident modules
8706 feature to mark modules as resident if they export
8707 `m4_resident_module' as TRUE.
8708 (m4_module_unload): Do not remove resident modules, and take care
8709 with symbol insertion and deletion with resident modules.
8710 * m4/ltdl.c, m4/ltdl.h: Update to latest unreleased versions to
8711 use resident modules feature.
8713 2000-11-30 Gary V. Vaughan <gary@gnu.org>

8719 * modules/README: Updated.
8720 * doc/m4.texinfo: Updated.
8722 * modules/gnu.c (builtin_functions): Make indir orthogonal to
8723 builtin, in that each is recognised as a macro only with parameters
8724 (builtin_indir): Passing 0 arguments is now an error, as with
8725 builtin.
8727 * src/main.c (usage): Added missing description of `-c' option.
8729 2000-11-29 Gary V. Vaughan <gary@gnu.org>
8731 Consolidate the myriad of dispersed test scripts into the
8732 tests subdirectory. I think I now have all the file where I
8733 want them, so there shouldn't be anymore upheaval =)O|
8734 Honest!
8735 * tests/Makefile.am: Updated to run the new tests added below.
8736 * tests/other-tests/capitalize.test, tests/other-tests/comments.test,

8752 tests/other-tests/wrap.test: New tests based on the contents
8753 of the tests removed below.
8754 * examples/Makefile.am, modules/Makefile.am: Updated to
8755 reflect removed tests.
8756 * examples/defs,modules/defs: Removed.

8772 modules/unfrozen.m4, modules/unload.test: Removed.
8774 Move the implementation of GMP support for the mpeval() builtin
8775 into a loadable module that depends on libgmp. mpeval() and
8776 eval() share a common parser, now in m4/evalparser.c; the code
8777 in m4/numb.c and m4/numb.h is now physically split between
8778 m4/eval.c (the eval() backend) and modules/mpeval.c (the
8779 mpeval() backend), rather than being differentiated by cpp
8780 macros and multiple inclusion. The mpeval module is always
8781 built but will generate an diagnostic if it is used from an
8782 installation that didn't link in the gmp library.
8783 * modules/Makefile.am: build and install the new mpeval module.
8784 * modules/mpeval.c: Now contains the former parts of m4/numb.c
8785 and m4/numb.h that are required for gmp support in mpeval().
8786 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
8787 * m4/evalmp.c: Removed.
8788 * m4/m4module.h: Removed conditional prototype for
8789 m4_mp_evaluate().
8790 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
8791 and m4/numb.h that do not rely on gmp.
8792 * m4/evalparse.c: New file, contains the shared parts of the
8793 eval() and evalmp() parser implementations, and is no longer
8794 unencumbered by cpp magic to uncover the right parts.
8795 * m4/numb.h: Removed. It's former contents are split between
8796 m4/eval.c and modules/mpeval.c.
8797 * m4/numb.c: ditto.
8799 * tests/other-tests/changeword.test: New test. Rudimentary
8800 testing of changeword builtin runs only if --wnable-changeword
8801 was used at configure time.
8802 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
8803 alternation correctly. Split into two expressions to compensate.
8804 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
8805 * modules/Makefile.am: Build changeword module.
8806 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
8807 only when --enable-changeword was passed to configure.
8808 (builtin_changeword): If --enable-changeword was not used, then
8809 report that changeword() builtin has no support in m4 binary.
8811 2000-11-28 Gary V. Vaughan <gary@gnu.org>
8813 * src/main.c (main): Fixed a particularly nasty bug is
8814 user_search_path setting -- the -M flag processing must be
8815 extremely careful with search path ordering, or else the default
8816 installed module directory (possibly containing modules from a
8817 previous release) is placed earlier in the search path than any -M
8818 arguments (which are relied upon to load uninstalled modules with
8819 most of the tests in the regresion suite).
8821 * modules/load.c (builtin_load): Nasty hack to prevent adding
8822 symbols to symtab again if a module is loaded more than once.
8823 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
8825 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
8826 possible NULL pointer dereference.
8828 * m4/module.c (m4_module_find_by_modname): Renamed from
8829 m4_module_modname_find. Fixed all references.
8830 (m4_module_find_by_builtin): New function.
8832 * modules/modfreeze.test: load the `load' module with each
8833 invocation.
8834 * src/freeze.c (produce_frozen_state): Simplified in light of
8835 module field in m4_symbol. Allow a third argument for text macros
8836 to name the originating module.
8837 (reload_frozen_state): ditto.
8838 * m4/m4module.h: Fixup prototypes.
8839 * m4/builtin.h (m4_builtin_define): Add a module argument so
8840 that symbols can be registered against the defining module.
8841 (m4_macro_define): ditto.
8842 * m4/m4private.h (m4_symbol): Make the module field const to save
8843 on casting in the rest of the code.
8844 (SYMBOL_MODULE): New macro.
8846 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
8847 symbol reference maintenance bugs when removing a symbol from the
8848 symtab.
8850 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
8852 2000-11-27 Gary V. Vaughan <gary@gnu.org>
8854 * configure.in (m4_cv_func_obstack): A better check for whether
8855 libc has an obstack implementation.
8856 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
8858 * configure.in (--with-modules): Changed semantics. This
8859 option is now used to list modules to be preopened.
8860 * src/m4.h: #include "ltdl.h" unconditionally.
8861 * src/main.c: Removed all dependencies on WITH_MODULES.
8862 * src/freeze.c: ditto.
8863 * modules/Makefile.am: ditto.
8864 * m4/m4.c (builtin_m4exit): ditto.
8865 * modules/modpath1.test: ditto.
8866 * modules/modpath2.test: ditto.
8867 * modules/modpath3.test: ditto.
8868 * modules/modpath4.test: ditto.
8869 * modules/modtest.test: ditto.
8870 * modules/shadow.test: ditto.
8871 * modules/unload.test: ditto.
8873 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
8874 comes up on demand in LTLIBOBJS now.
8875 * configure.in (getopt_long): Creating and relying on a link for
8876 getopt.h on hosts with no getopt_long() of thier own works
8877 correctly now. This is necessary so that callers of getopt_long()
8878 can simply `#include <getopt.h>': the naive way of doing this
8879 would end up using our own getopt.h and the installed
8880 getopt_long(), which is asking for trouble!
8881 (obstack_init): A similar argument applies to obstack.h and
8882 obstack_init().
8884 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
8885 On Solaris-2.5 (at least) the native dlopen implementation
8886 gets confused about m4.o when looking for module "m4". This
8887 version always looks for .la an .$lib_ext suffixed names first
8888 to work around the problem. Sigh.
8890 * po/POTFILES.in: Take account of these file movements.
8891 * src/Makefile.am (m4_SOURCES): removed eval.c.
8892 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
8893 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
8894 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
8895 * modules/m4.c (builtin_eval): Use m4_evaluate().
8896 * m4/eval.c: Moved here from src/eval.c to facilitate
8897 implementation of eval() builtin as part of the `m4' loadable
8898 module.
8899 (m4_evaluate): renamed from evaluate for namespace cleanliness.
8900 * m4/numb.c: Moved here from src/numb.c, since it is #included
8901 into eval.c at compile time.
8902 * m4/m4module.h (m4_evaluate): Added prototype.
8903 * src/m4.h (evaluate): Removed prototype.
8905 2000-11-25 Gary V. Vaughan <gary@gnu.org>
8907 * modules/perl.c (builtin_perleval): Use PL_na for
8908 compatibility with perl-5.6.
8910 * src/main.c (main): It is now safe to
8911 ``m4_module_install("m4")'', without tripping over the m4
8912 binary itself!
8913 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
8914 versions having fixed the insidious module search order bug.
8916 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
8917 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
8919 * configure.in: Figure out whether to use the installed
8920 getopt.h or the supplied one.
8921 * src/Makefile.am: ditto.
8923 * po/POTFILES.in: List files in their new positions.
8925 * config/ltmain.sh: This needs to be checked in to match the
8926 libtool macros copied to acinclude.m4 (until a released
8927 libtool copes with m4's needs).
8928 * bootstrap: Run gettextize.
8930 2000-11-24 Gary V. Vaughan <gary@gnu.org>

8977 started in `no_gnu_extensions' mode.
8978 * modules/traditional.c: New file implementing the ``unix'' macro,
8979 required when m4 is executed in traditional mode, as a loadable
8980 module.

8992 the migration of all builtin implementations to loadable modules.
8993 * m4/macro.c: Moved this file here from the src directory,
8994 renaming all exported symbols to use the prefix ``m4_''.
8995 * m4/builtin.c: ditto.
8996 * m4/module.c: ditto.
8997 * m4/symtab.c: ditto.
8998 * m4/debug.c: ditto.

9004 directory to facilitate builtin migration.
9006 2000-08-12 Gary V. Vaughan <gary@gnu.org>
9008 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
9009 error message, to make translators' jobs a little easier.

9039 makeinfo calculates them for us, and to make any future
9040 reorganisation easier.
9041 (Frozen files): Document format version 2.
9042 `V' now takes argument `2'.
9043 `F' can take a single argument if symbol and builtin names
9044 are the same, or 3 arguments if the builtin is from a module.
9045 New `S' specification for saving syntax table contents.
9046 New `M' specification for saving loaded module names.

9260 src dir and immediately after libm4 is built for confidence that
9261 it doesn't rely on the src directory.
9262 (SUBDIRS): Moved doc dir to the end since helptoman.pl and
9263 makeinfo stop the build on cygwin (because they don't work).
9265 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
9267 * m4/m4private.h: ...is not a public header, so moved to src.
9268 Add `#include <config.h>', `#define _COMPILING_M4' and
9269 `#include "m4.h".
9270 * m4/Makefile.am (noinst_HEADERS): remove m4private.h.
9271 * src/Makefile.am (noinst_HEADERS): add m4private.h.

9294 m4/libm4.la.
9295 * m4/m4error.h: Renamed error.h, for installation to
9296 $prefix/include/m4..
9297 * m4/m4obstack.h: Renamed obstack.h, for same reason.
9298 * m4/m4regex.h: Renamed regex.h, for same reason.
9299 * m4/m4error.c: Renamed error.c, and use #include "error.h".
9300 * m4/m4obstack.c: Renamed obstack.c, and fix #includes.
9301 * m4/m4regex.c: Renamed regex.c, and fix #includes.
9303 * lib: moved to m4 to easily support header installation to
9304 $prefix/include/m4.
9305 * Makefile.am (SUBDIRS): renamed lib dir to m4.
9306 * configure.in (AC_OUTPUT): reference m4/Makefile.in.
9307 * acm4/regex.m4: Point to m4/regex.c.
9309 * examples/foreach.m4: Sanitise quoting.
9310 * examples/foreach.test: New torture test.
9311 From Akim Demaille <akim@epita.fr>
9313 2000-01-17 Gary V. Vaughan <gary@gnu.org>
9315 * src/ltdl.c: Use access() to abort doomed module load attempts
9316 if module file does not exist.
9318 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
9319 getopt1.o will already be used if appropriate, so I moved getopt.c
9320 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
9322 * modules/modpath1.test: Use correct filename in header line.
9323 * modules/modpath2.test: ditto.
9324 * modules/modpath3.test: ditto.
9325 * modules/modpath4.test: ditto.
9327 Without these changes lt_dlopen("test") attempts to
9328 LoadLibrary("/bin/test") on Windows, which although harmless
9329 generates a spurious error message which spoils most of the tests:
9330 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
9331 (TESTS): s/test.test /modtest.test /
9332 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /
9333 (test_la_SOURCES, test_la_LDFLAGS): renamed to use modtest.
9334 * modules/modpath1.test: s/test.m4 /modtest.m4 /
9335 * modules/modpath2.test: ditto.
9336 * modules/modpath4.test: ditto.
9337 * modules/modpath3.test: s/-m test /-m modtest /
9338 * modules/shadow.m4: use {un,}loadmodule(`modtest').
9340 2000-01-16 Gary V. Vaughan <gary@gnu.org>
9342 * src/ltdl.c (find_file): Updated to new version with fixed memory
9343 allocation bug in `next'.
9344 * src/ltdl.h: updated to match.
9346 * modules/Makefile.am: Cleaned up and reordered.
9348 2000-01-16 René Seindal <rene@seindal.dk>
9350 * modules/Makefile.am (TESTS): New tests for the module system.
9352 * modules/*.test: New files.
9354 * src/m4.c (main): Added call to module_init().
9355 Treats -M and -m as the arguments -D -U and -t, ie deferred.
9357 * src/m4.h: Added declaration of module_init().
9359 * src/module.c (module_init): No longer static
9361 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
9362 Added to shut up automake about non standard libtool library
9363 names.
9365 * src/module.c: Disabled DEBUG by default.
9367 * modules/README: Changed example from unload.m4 to shadow.m4
9369 * modules/shadow.m4: Renamed from unload.m4
9371 * modules/Makefile.am (EXTRA_DIST): Removed unload.m4.
9373 * src/m4.c (main): Functionality for -m and -M were reversed.
9374 Fixed.
9376 2000-01-12 Gary V. Vaughan <gary@gnu.org>
9378 * doc/help2man.pl: updated to version 1.020.
9380 * lib/COPYING.LIB: updated to version 2.1.
9382 * lib/m4module.h: restructure the M4_SCOPE code to work when
9383 creating a dll which links with libm4.la and both DLL_EXPORT
9384 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
9385 both defined.
9387 2000-01-11 Gary V. Vaughan <gary@gnu.org>
9389 Merged the following changes from my tree:
9391 1999-06-15 Gary V. Vaughan <gary@gnu.org>
9393 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
9394 ported to compile shared libs.
9396 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
9397 use `__declspec(dllimport)' when linking libm4.la on win32.
9398 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
9400 * configure.in (M4OBJS): Discover whether we need the shipped
9401 implementation of getopt_long.
9402 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
9403 main binary here, as opposed to the module library in lib/libm4.la.
9405 1999-06-14 Gary V. Vaughan <gary@gnu.org>
9407 * modules/README: Updated to describe the improved libltdl based
9408 module scheme.
9409 * README (cygwin): Added some compilation notes for building m4
9410 correctly under cygwin.
9411 * TODO: Cleaned out the entries for the module system since they
9412 are now implemented.
9414 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
9415 all instances of __P with M4_PARAMS.
9417 * lib/getdate.h: removed unreferenced file.
9419 * lib/m4private.h: New file to define the private interface to the
9420 token_data struct, which must be shared between m4module.c, and
9421 builtin.c but not exported to modules built from the installed
9422 m4module.h since it's size changes depending on compile time
9423 options.
9425 * src/m4.h: Lots of stuff moved to lib/m4module.h.
9427 * lib/m4module.h: New file to define the interface available when
9428 compiling m4 modules.
9429 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
9430 necessary for module compilation into this new file.
9432 * lib/Makefile.am (include_HEADERS): install headers (renamed to
9433 avoid nameclash with other system headers) necessary for compiling
9434 modules.
9435 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
9436 so that modules can include the (renamed) installed headers and
9437 be guaranteed a matching implementation.
9438 * lib/m4error.h: renamed from error.h.
9439 * lib/m4obstack.h: renamed from obstack.h.
9440 * lib/m4regex.h: renamed from regex.h.
9441 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
9442 implementation, simply include the shipped version
9443 unconditionally, otherwise it is hard for a module to know
9444 whether the m4obstack.h header it is using matches the
9445 implementation it ends up linking against.
9446 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
9447 the same reason.
9449 1999-05-18 Gary V. Vaughan <gary@gnu.org>
9451 * examples/misc.test: Don't run this test on machines which don't
9452 have a root user in /etc/passwd (e.g. cygwin).
9454 * tests/get-them (/^@example$/): Error messages might have a
9455 ``.exe'' suffix to the program name, or else use the libtool
9456 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
9457 of these cases are now catered for when comparing error messages
9458 in generated tests.
9459 * tests/other-tests/*.test: ditto.
9460 * examples/*.test: ditto.
9462 * tests/defs (M4): use libtool execute mode.
9463 * examples/defs (M4): ditto.
9465 * tests/get-them (END): explicitly close any open file.
9466 (printthem): In a regular expression, '{' is the start of a repeat
9467 count! Use `[{]' for a literal open brace.
9468 (/^@node /): Don't use substr on a string shorter than the trim
9469 length.
9471 1999-05-17 Gary V. Vaughan <gary@gnu.org>
9473 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
9474 substituted.
9475 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
9477 2000-01-10 Andreas Schwab <schwab@suse.de>
9479 * tests/other-tests/gmp.test: Find config.sh in build directory.
9481 * configure.in: Find tests/mkconfig.sh in $srcdir.
9483 * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in
9484 <signal.h> (for SUS2 compliant systems).
9486 * src/stackovf.c: Check for HAVE_SIGINFO_T in addition to
9487 HAVE_SIGINFO_H.
9489 2000-01-10 René Seindal <rene@seindal.dk>
9491 * Prerelease 1.4o.
9493 * TODO, NEWS: Cleaned up and updated.
9495 * src/m4.c (main): New variable exit_status for exit status in
9496 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
9497 file cannot be read instead of EXIT_SUCCESS.
9499 * src/builtin.c (m4_indir): Changed error message to help
9500 translators (from Akim Demaille <demaille@inf.enst.fr>).
9502 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
9503 Cygnus.
9505 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
9506 from glic 2.1.2.
9508 * src/input.c (match_input): Reordering of code, to avoid multiple
9509 calls to push_string_init() from obstack_grow(), which can happen
9510 with some compilers (found and fixed by James Bonfield
9511 <jkb@mrc-lmb.cam.ac.uk>).
9513 * src/stackovf.c: Added prototypes for ultrix.
9514 (setup_stackovf_trap): Added __P to cast.
9515 (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>)
9517 2000-01-09 René Seindal <rene@seindal.dk>
9519 * doc/m4.texinfo (Changequote): Added comment about changing
9520 quotes when the old quote is a part of the new.
9522 * src/builtin.c (expand_ranges): Added break after trailing dash.
9523 This caused misbehavious on some systems (found and fixed by Akim
9524 Demaille <demaille@inf.enst.fr>).
9526 * AUTHORS: Thomas Tanner included
9528 * acconfig.h: Added entry for ss_sp (see below).
9530 * configure.in (use_stackovf): Added check for stack_t with member
9531 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert
9532 <eggert@twinsun.com>).
9534 * doc/m4.texinfo (Frozen files): Added a simpler example for
9535 generating frozen files from several input files.
9537 1999-11-14 Paul Eggert <eggert@twinsun.com>
9539 * po/POTFILES.in: Add lib/getopt.c, lib/obstack.c,
9540 lib/regex.c, lib/xmalloc.c.
9542 1999-11-10 René Seindal <rene@seindal.dk>
9544 * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal.
9546 * src/module.c: reindented.
9547 (module_load): return if this is a repeated load of same module.
9548 (module_init): slight change of logic to avoid repeated
9549 initialisation debug messages.
9551 * Makefile.am (DIST_SUBDIRS): Added to ensure modules/ is included
9552 in the distribution.
9554 * modules/Makefile.am (test_la_LDFLAGS): set to -module to silence
9555 automake warnings about missing lib prefix.
9556 (time_la_LDFLAGS): ditto
9557 (stdlib_la_LDFLAGS): ditto
9559 1999-11-10 Paul Eggert <eggert@twinsun.com>
9561 * src/m4.h: Include error.h, since our macros use error.
9562 * src/m4.c: Don't need to include error.h.
9564 1999-11-09 Paul Eggert <eggert@twinsun.com>
9566 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
9567 and zero, as Solaris 7 cc does.
9568 (bcopy): Remove macro; no longer needed with new obstack.h.
9570 * src/output.c (freeze_diversions): Don't assume that a
9571 diversion size can fit in `int'. Check for diversion file
9572 size too large to be printed with `unsigned long'.
9574 * src/Makefile.am (CFLAGS): Omit -Wall.
9576 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.
9578 * src/debug.c (trace_format):
9579 Use ANSI C if (defined __STDC__ && __STDC__) || defined PROTOTYPES.
9581 * src/freeze.c (produce_frozen_state):
9582 Don't assume string lengths fit in int.
9584 1999-10-13 René Seindal <rene@seindal.dk>

9598 * configure.in (ALL_LINGUAS): Added Greek translation (el).
9599 (ALL_LINGUAS): Added Czech translation (cs).
9601 1999-03-30 Gary V. Vaughan <gary@gnu.org>
9603 * src/builtin.c: moved module loading functions into...
9604 * src/module.c: entirely new implementation using libltdl.
9605 * po/POTFILES.in: added src/module.c.
9606 * modules/Makefile.am (LTLIBRARIES): Removed lib prefix as these
9607 are modules, not linktime libraries.
9608 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
9609 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
9610 avoidance on exported symbols.
9611 * modules/test.c (m4_macro_table, m4_init_module,
9612 m4_finish_module): ditto.
9613 * modules/time.c (m4_macro_table): ditto.
9615 * modules/time2.m4: new file which requires command line loading
9616 of modules.
9617 * src/m4.c (--load-module): dynamically load named runtime module
9618 into running executable before reading the source.
9619 (--module-directory): prepend a directory to the module search
9620 path.
9621 (module_init()): Do this the first time we load a module instead;
9622 if the module subsystem is broken normal m4 scripts can still run.
9623 * src/m4.h (install_builtin_table): is now exported.
9625 1999-03-26 Gary V. Vaughan <gary@gnu.org>
9627 * src/module.c: removed. No longer required.
9628 * po/POTFILES.in: removed src/module.c.
9630 * Makefile.am (MAINTAINERCLEANFILES): Remove all the files that
9631 the bootstrap script can recreate.
9632 * acm4/Makefile.am (MAINTAINERCLEANFILES): ditto.
9633 * doc/Makefile.am (MAINTAINERCLEANFILES): ditto.
9634 * examples/Makefile.am (MAINTAINERCLEANFILES): ditto.
9635 * lib/Makefile.am (MAINTAINERCLEANFILES): ditto.
9636 (AUTOMAKE_OPTIONS): reduced strictness to allow COPYING.LIB.
9637 * modules/Makefile.am (MAINTAINERCLEANFILES): ditto.
9638 * src/Makefile.am (MAINTAINERCLEANFILES): ditto.
9639 * tests/Makefile.am (MAINTAINERCLEANFILES): ditto.
9641 * acinclude.m4: removed. `aclocal -I acm4' handles this much
9642 better.
9643 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
9644 * acm4/gettext.m4: removed. It causes a multiple definition vs.
9645 the installed gettext.m4 file when running aclocal.
9647 1999-03-25 Gary V. Vaughan <gary@gnu.org>
9649 * configure.in (AM_INIT_AUTOMAKE): bumped version number to
9650 distinguish this from the last prerelease.
9651 (AC_LIBLTDL_CONVENIENCE): build libltdl as a convenience library
9652 in its own subdirectory.
9654 * modules/Makefile.am (*_SOURCES): renamed to use libtool's "no
9655 lib prefix on a module" feature.
9656 (LDFLAGS): Added `-module -avoid-version' flags to build
9657 versionless module libraries.
9658 * src/builtin.c (m4_load_module): use libltdl.
9659 (module_unload_all): use libltdl.
9660 * src/m4.c (module_init): initialise module loading on demand for
9661 better diagnostics, and so that m4 will still work even if
9662 the module code is broken.
9663 * src/m4.h (module_init): removed. No longer relevant.
9664 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on
9665 exported symbols for compatibility with dlpreopening.
9666 * modules/test.c (m4_macro_table, m4_init_module,
9667 m4_finish_module): ditto.
9668 * modules/time.c (m4_macro_table): ditto.
9670 * bootstrap: New file. Runs all the autoutils in the right order
9671 after a fresh checkout, or a make maintainer-clean.
9673 1999-02-18 Akim Demaille <demaille@inf.enst.fr>
9675 * src/builtin.c (dump_symbols): New function, factoring common
9676 content of m4_dumpdef and m4_symbols.
9677 (m4_dumpdef): Use it.
9678 (m4_symbols): New function, implementing `symbols'. Use it.
9679 * doc/m4.texinfo: Fixed missing commas after @xref, so that the
9680 file compile with modern makeinfo.
9681 (Symbols): New node, documenting symbols.
9682 (direntry): Modernize.
9684 1998-12-11 René Seindal <rene@seindal.dk>
9686 * src/builtin.c (predefined_tab): New predefined macros
9687 __m4_changeword__, __m4_gmp__ and __m4_modules__ for testing for
9688 configure time options.
9690 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
9692 * src/module.c (module_try_load): Don't try to be clever and
9693 overwrite argument string. Instead allocate all constructed
9694 strings locally, since they can have arbitrary lengths. Make
9695 arguments pointers to const.
9696 (module_search): Simplify due to above change.
9698 1998-11-29 René Seindal <rene@seindal.dk>
9700 * Prerelease 1.4n.
9702 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): New tests.
9704 * tests/other-tests/import-environment.{m4,test}: New test.
9706 * tests/other-tests/discard-comments.{m4,test}: New test.
9708 * doc/m4.texinfo (Invoking m4): Updated for --discard-comments.
9710 * src/m4.c (main): New option -c --discard-comments.
9711 New global variable discard_comments.
9713 * src/m4.h (token_type): New TOKEN_NONE for tokens to be
9714 discarded, ie never returned from next_token().
9715 Added declaration of discard_comments.
9717 * src/input.c (next_token): Now loops until token type is not
9718 TOKEN_NONE. Comments are now given this type when comments should
9719 be discarded.
9721 * doc/m4.texinfo (Invoking m4): Updated for --import-environment
9722 and mpeval.
9724 1998-11-28 René Seindal <rene@seindal.dk>
9726 * src/m4.c (main): New option --import-environment (no single
9727 letter option).
9729 * When configured with --with-gmp both the normal (fast) eval()
9730 and the gmp aware mpeval() are defined. To restore previous
9731 bahaviour use "define(`eval', defn(`mpeval'))".
9733 * tests/other-tests/gmp.m4: Changed to use mpeval().
9735 * src/evalmp.c: New file for compiling eval.c as gmp aware.
9736 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
9738 * src/eval.c: Now includes "numb.c" directly. Everything in this
9739 file must by static, except evaluate(), which is changed to
9740 mp_evaluate() if USE_GMP in force.
9742 * src/numb.c: Changed to be included by eval.c instead of being
9743 compiled separately. Everything is declared static.
9745 * src/numb.h: Removed declarations of functions, as numb.c is now
9746 included by eval.c.
9748 * src/builtin.c: Declaration of m4_mpeval() added.
9749 Inserted `mpeval' in builtin table.
9750 (do_eval): New function with common code for m4_eval and m4_mpeval.
9751 (m4_mpeval): New function for gmp version of eval.
9753 * src/m4.h: Declaration of mp_evaluate().
9755 * src/Makefile.am (m4_SOUCES): Includes mpeval.c.
9756 (EXTRA_m4_SOURCES): Now has numb.c and numb.h
9758 * src/m4.c (main): m4 --version also shows which options were used
9759 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
9761 1998-11-27 René Seindal <rene@seindal.dk>
9763 * Error messages now always print program name before input file
9764 name as specified by GNU coding standards. Reported by Akim
9765 Demaille <demaille@inf.enst.fr>.
9767 * doc/m4.texinfo (Include): Change due to changed error message
9768 format.
9769 (Eval): Do.
9771 * tests/get-them: Minor change to sed script due to changed error
9772 message format.
9774 * src/m4.c (print_program_name): New func used to print program
9775 name, input file and line number in error (). Used as an
9776 error_print_progname handler.
9777 (reference_error): Removed.
9778 (main): Assigns error_print_progname.
9780 * src/m4.h (M4ERROR): Removed reference_error ().
9782 1998-11-25 René Seindal <rene@seindal.dk>
9784 * Updated to libtool 1.2b.
9786 * src/builtin.c (install_builtin_table): Added braces to avoid
9787 warning of ambiguous 'else'.
9789 * src/module.c: Inserted search path code from path.c modified to
9790 use new interface.
9791 (module_init): Configured default path used only if M4MODPATH is
9792 not set.
9793 (module_try_load): Now reads libMODULE.la as generated by libtool
9794 for actual module name.
9795 (module_load): Gives better error messages on failure.
9797 * src/m4.h: Added declarations of structures and functions for
9798 generic search path handling.
9800 * src/path.c: Removed all module specific code and introduced new
9801 functions of more generic search path handling.
9803 1998-11-24 René Seindal <rene@seindal.dk>
9805 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
9806 included gettext, as <libintl.h> might not be found
9807 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
9809 1998-11-22 René Seindal <rene@seindal.dk>
9811 * src/output.c (insert_diversion): Fixed bug that might cause m4
9812 to read from standard output! Triggered by input
9813 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
9814 so now 'undivert(0)' does nothing.
9816 1998-11-18 René Seindal <rene@seindal.dk>
9818 * Prerelease 1.4m.
9820 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
9821 could be changed when compiling a illegal regexp, causing later

9886 where modules are installed.
9888 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
9889 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
9890 build and install automatically, and it is prepared for other
9891 interfacec than dlopen().
9893 * src/builtin.c (predefined_tab): Added __m4_version__ for the
9894 current version of GNU m4. It is a GNU extension.

9976 * Prerelease 1.4j.
9978 * tests/Makefile.am (GENERATED_TESTS): Changed .m4 extension to
9979 .test, as the files are no longer just m4 input.
9981 * tests/get-them (FILE): Changed .m4 extension to .test.
9983 * src/m4.h (token_type): New token type TOKEN_SPACE introduced.
9984 Otherwise quoted strings with leading whitespace first in a macro
9985 argument would be eliminated.
9987 * src/macro.c (expand_token): Handles new token type TOKEN_SPACE.
9988 (expand_argument): Do.
9990 * src/input.c (next_token): SPACE and NUM/OTHER characters are only
9991 grouped together iff both quote and comment strings are single
9992 character. Otherwise they might include a comment/quote leader.

9995 * src/builtin.c (push_builtin_table): New function to push a
9996 builtin_table on the stack without installing its contents.
9997 (find_builtin_by_name): Added call to push_builtin_table() if
9998 reading frozen files. Otherwise the builtins named in the frozen

10024 * src/builtin.h: New file, declares some functions from builtin.c
10025 that are of use for other modules (shipout_int, numeric_arg,
10026 skip_space, bad_argc), and the macros ARG() and DECLARE().
10028 * src/builtin.c (install_builtin_table): New function. Each
10029 module brings in a builtin_table, which is pushed on a stack.
10030 (struct builtin_table): New struct for list of builtin_tables.

10044 in path.c.
10046 * src/m4.c (main): Added call to module_init().
10048 * modules: New directory with a few demo modules.
10050 * Makefile.am (EXTRA_DIST): Added modules/* since modules/ is not
10051 in SUBDIRS.
10053 * configure.in: Added modules/Makefile to AC_OUTPUT.
10055 * configure.in: Added code to implement --with-modules. Tests for
10056 <dlfcn.h> and -ldl.
10058 * acconfig.h: Added WITH_MODULES
10060 1998-10-02 René Seindal <rene@seindal.dk>
10062 * examples/Makefile.am (pkgdata_DATA): Removed special target for
10063 check and variables TESTS. These tests are now run from the
10064 tests/ directory.
10066 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
10067 directory. The files stay there but the tests are run from the
10068 tests/ directory.
10070 * tests/Makefile.am (EXTRA_DIST): Added run-test.
10072 * tests/run-test: New file. Run a test manually
10074 * tests/Makefile.am, tests/get_them: Moved automatically generated
10075 tests (from the manual) to sub directory tests/gentest/. The
10076 tests/ directory had gotten a bit messy.
10078 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10080 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\

10083 1998-08-21 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10085 * Prerelease 1.4h.
10087 * lib/Makefile.am (noinst_HEADERS): regex.h added
10089 * configure.in (jm_WITH_REGEX, jm_PREREQ_ERROR):
10090 acm4/{error,regex}.m4 (from fileutils-3.16u.tar.gz).
10092 * acm4/Makefile.am: created providing rules to create
10093 $(top_srcdir)/acinclude.m4 to be used by aclocal.
10095 * tests/defs (LANGUAGE, LC_ALL, LANG): force them to be
10096 `C'. Reported by Ulrich Drepper.
10098 * Makefile.am (SUBDIRS): Removed checks directory
10099 * configure.in (AC_OUTPUT): Removed checks/Makefile
10101 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
10102 the space when m4.texinfo is edited and whitespace.el is active.
10103 (Defn,example): idem.
10105 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10107 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
10108 ../COPYING. ../Makefile is a file which is certainly present when
10109 test is executed in testSubDir. One can't be sure that the COPYING
10110 file is in .. or ../.. in all situations, the ../Makefile is
10111 always there.
10113 * doc/m4.texinfo (Include): adjusted expected test output
10114 according to new tests, i.e. the input will always come from the
10115 file `in' created by the test.
10117 * tests/Makefile.am: Added three lines at the top to get
10118 esyscmd.1.test working.
10120 * tests/get-them: modified to generate clearer tests who will need
10121 less maintenance when new test examples are created in
10122 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
10123 need the generic file `defs') shell scripts creating `in', `ok',
10124 `out' and when apropriate `okerr' and `err' in the directory
10125 `testSubDir' when executed. The compare of `ok' and `out'
10126 (and of `okerr' and `err') will be the exit status of the test.
10127 `out' must match `ok' (and `okerr' must match `err') for the test
10128 to be succesful.
10130 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
10131 the tests generated by tests/get-them getting it input normally
10132 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
10133 (dot) before the numeric part) is reserved for all other (hand
10134 written) tests. The `+' means one or more times.
10136 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10138 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
10139 supported short man page to refer to info documentation
10140 * helptoman.pl: added
10141 * configure.in: AC_PATH_PROG(PERL,perl)
10142 * Makefile.am (SUBDIRS): doc after src
10144 * libitized with libit 0.5 from
10145 ftp://ftp.iro.umontreal.ca/pub/contrib/pinard/maintenance/libit.

10152 * configure.in (AC_CHECK_FUNC): getopt_long
10154 * src/m4.c (usage): Report bugs to m4-bugs@gnu.org.
10156 * TODO: added entry about dependencies
10158 1998-08-10 René Seindal <rene@seindal.dk>
10160 * Prerelease 1.4f
10162 * doc/m4.texinfo (Changesyntax): Added documentation for the macro
10163 "changesyntax".
10165 * src/builtin.c (m4_changesyntax): Added builtin macro
10166 "changesyntax" to modify the syntax table.
10168 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax
10169 table. All categories are assigned a syntax code and tokens are
10170 read according to this table.
10172 1998-08-09 René Seindal <rene@seindal.dk>
10174 * src/numb.{c,h}: New files, implements multiple precision eval
10175 using GNU gmp. Originally submitted by John Gerard Makecki
10176 (johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.
10178 * doc/m4.texinfo (Eval): Added documentation for multiple
10179 precision arithmetic library support.
10181 * src/m4.{c,h}, src/eval.c, src/builtin.c, configure.in: Changes
10182 to accommodate multiple precision eval.
10184 1998-08-07 René Seindal <rene@seindal.dk>
10186 * src/input.c (MATCH, match_input), src/m4.h: changed definition
10187 of comment and quote strings to `unsigned int' to allow eight bit
10188 chars (reported by andrewb@zip.com.au (Andrew Bettison)).
10190 * src/builtin.c, doc/m4.texinfo: Builtin `syncoutput' added by
10191 patch from Mike Howard <mike@clove.com>
10193 1998-08-06 René Seindal <rene@seindal.dk>
10195 * gettext.m4: corrected AM_WITH_NLS to handle use of installed
10196 -lintl.
10198 1998-08-03 René Seindal <rene@seindal.dk>

10205 * src/m4.c (main): reintroduced textdomain(PACKAGE) to get gettext
10206 to look for right message catalogs. Call indef'ed by ENABLE_NLS.
10208 * configure.in (ALL_LINGUAS): Added complete list of translations:
10209 de fr it ja nl ru sv.
10211 1998-05-23 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10213 * po/nl.po: Dutch translation by Erick Branderhorst.

10220 * Prerelease 1.4d.
10222 * src/m4.c: #include <signal.h> not <sys/signal.h>.
10224 * src/Makefile.am: CFLAGS = -Wall @CFLAGS@.

10228 * configure.in, {,src,doc,lib,examples,checks}/Makefile.am,
10229 src/{ansi2knr.{1,c}} doc/{m4.texinfo,mdate-sh}, missing,
10230 mkinstalldirs, install-sh: Added automake (1.3) support.

10234 Used libitize (0.4) to update.
10236 * configure.in, ABOUT-NLS, intl/*, po/*: Added gettextize
10237 (0.10.25) support. Removed LOCALE, fr.msg, m4.cod and adjusted
10238 README accordingly.

10288 be opened, return immediately after producing the error message.
10289 Reported by Andreas Schwab.
10291 * configure.in: Check for const only after having found possible
10292 ANSIfying compiler flags, this is of no use to check it before.
10293 Reported by Alexander Lehmann.
10295 1994-11-01 François Pinard <pinard@iro.umontreal.ca>
10297 * src/macro.c (collect_arguments): Cast obstack arguments to

10342 of $U, put underline in extensions rather than in basenames. Use
10343 implicit rules, now that regularity makes this possible.
10344 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
10345 of ansi2knr whenever it is needed.
10346 * configure.in: Adjusted for correct STACKOVF substitution.
10347 * src/debug.c (trace_format): When not __STDC__, use (...) as a
10348 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.
10349 Reported by David MacKenzie.
10351 * Makefile.in: Remove binprefix. Use transform_name instead.
10352 Reported by David MacKenzie.
10354 * doc/Makefile.in: Create version.texi, use it, clean it.
10355 Reported by Jim Meyering.
10357 1994-10-28 François Pinard <pinard@iro.umontreal.ca>
10359 * Makefile.in (all, install, uninstall): Depend on Makefile.
10361 * Makefile.in: For actions invoking $(MAKE) from within compound

10364 Reported by Jim Kingdon.
10366 * {,/*}Makefile.in: Use && after all cd, in case they fail.
10368 * {,*/}Makefile.in: Declare PRODUCT and VERSION macros.

10420 * {doc,examples,lib,src}/Makefile.in (check): Deleted, as
10421 unreacheable and useless.
10423 * doc/Makefile.in (texclean): Deleted, merged in mostlyclean.
10425 * lib/Makefile.in (DISTFILES): Distribute TAGS.
10426 (distclean): Do not remove TAGS.
10427 (realclean): Remove it.
10428 * Makefile.in: Make TAGS in lib also, not just in src.
10429 Reported by Karl Berry.
10431 * Makefile.in (distclean, realclean): Instead of recursively
10432 calling $(MAKE) for the -local part, allow parallel execution of
10433 -recursive and -local, only delay the removal of config.status,
10434 which is repeated in both goals.
10435 \f
10436 1994-09-13 François Pinard <pinard@iro.umontreal.ca>
10438 * Release 1.3.
10440 * Makefile.in: Group all *clean-recursive goals in one, using sed
10441 to remove `-recursive' while calling make recursively. Also, use
10442 a subshell for each recursive $(MAKE).
10443 Reported by Jim Meyering.
10445 * src/m4.h (memcpy): Define with bcopy for BSD systems.
10446 Reported by Kaveh R. Ghazi.
10448 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS
10449 4.1.3 requires -ldl to link even ansik2nr, and we need a way to
10450 specify it.
10452 * configure.in: Use date instead of touch for stamp-h.
10453 * Makefile.in (stamp-h.in): Idem.
10455 * Makefile.in (distclean, realclean): Force serial execution of

10476 Reported by Eric Backus.
10478 * Makefile.in, checks/Makefile.in, doc/Makefile.in,

10482 * configure.in (AC_OUTPUT): Touch stamp-h if CONFIG_HEADERS.
10483 Reported by Jim Meyering.
10485 1994-09-06 François Pinard <pinard@iro.umontreal.ca>
10487 * configure.in: Correct stack overflow detection logic, taking
10488 care of systems having only incomplete implementations (like for
10489 Pyramid 9820 OSx 5.0d).
10490 Reported by Kaveh R. Ghazi.
10492 * src/Makefile.in (TAGS): Remote -t from etags call.
10494 1994-09-02 François Pinard <pinard@iro.umontreal.ca>

10501 Reported by Jim Meyering and John David Anglin.
10503 * Makefile.in (distclean-local): Delete config.log.
10504 Reported by Jim Meyering.
10506 Solidify frozen files with respect to -P:
10507 * src/m4.c: Have -P set prefix_all_buitins variable instead of
10508 calling a function by that name. Declare the variable.
10509 * src/m4.h: Adjust declaration for prefix_all_buitins.
10510 * src/builtin.c (builtin_init): Merge in functionality from
10511 previous prefix_all_buitins function, while making entries in the
10512 symbol table, but not modifying the builtin description itself.
10514 * src/freeze.c (reload_frozen_state): Add a useless `break;',
10515 because *many* compilers do not accept an empty `default:'.

10517 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.
10519 * configure.in: Use AC_TYPE_SIGNAL.
10520 * src/stackovf.c (setup_stackovf_trap): Use RETSIGTYPE.
10521 Reported by Robert Bernstein.
10523 * checks/Makefile.in (check): Modify PATH so check-them will find
10524 m4 in the src directory.
10525 * Makefile.in (check): Don't.
10526 Reported by Akiko Matsushita and Jim Meyering.
10528 * src/output.c (make_room_for, output_character_helper): New
10529 functions, for implementing a global MAXIMUM_TOTAL_SIZE instead of
10530 a per buffer MAXIMUM_BUFFER_SIZE.
10532 * src/output.c (output_text): New function, for optimizing the
10533 output of strings of characters. Use it.
10535 1994-08-30 François Pinard <pinard@iro.umontreal.ca>

10539 files.
10540 * Makefile.in: Adjusted.
10541 * configure.in: Configure new Makefiles.
10543 * m4.h: Declare STRING typedef. Use it for comment and quote
10544 strings, adjusting all references. (This is the rudiments of a
10545 beginning for the eventual withdrawal of NUL terminated strings.)
10546 * output.c (shipout_text): Accept a length parameter, and use it.
10547 All callers adjusted.
10549 1994-08-29 François Pinard <pinard@iro.umontreal.ca>
10551 * m4.h: Include <unistd.h> if it exists.

10564 (output_init): Allocate only diversion 0.
10565 (make_diversion): Allocate new diversions as needed.
10566 * m4.h, m4.c: Remove NDIVERSIONS and ndiversion related stuff.

10568 Reported by David MacKenzie.
10570 Freeze diversions:
10571 * output.c (freeze_diversions): New function.
10572 * m4.h: Declare freeze_diversions.
10573 * freeze.c: Document frozen file format, revise it, call
10574 freeze_diversions to add diversions to frozen format, and code to
10575 reload them properly.
10576 * m4.c: Do not undivert automatically at end when status being
10577 frozen. Do not call builtin_init when reloading frozen state.
10579 Speed up diversion processing:
10580 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
10581 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
10582 structure and variables, cached variables out of output_diversion,
10583 reallocate_diversion_for and OUTPUT_CHARACTER.
10584 (shipout_text, make_diversion, insert_diversion): Adapted to new
10585 structures.
10586 (insert_file): Use better buffering.
10587 Reported by David MacKenzie.
10589 1994-08-28 François Pinard <pinard@iro.umontreal.ca>
10591 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
10592 dist works from another build directory.
10594 1994-08-27 François Pinard <pinard@iro.umontreal.ca>
10596 * symtab.c (hack_all_symbols): Use hash_table_size instead of
10597 constant HASHMAX, for -H option to work better.
10599 * builtin.c (DECLARE): Simplify by using _ ().
10601 * freeze.c: New file.
10602 * Makefile.in: Compile it, distribute it.
10603 * m4.c: Recognize, document and process --freeze-state (-F) and
10604 --reload-state (-R) options. Pass a true flag to builtin_init
10605 only if no reloading some state.
10606 * builtin.c (define_builtin): Remove static specifier.
10607 (find_builtin_by_name): Remove static specifier.
10608 (builtin_init): Accept and obey a flag argument.

10614 specifier.
10616 * configure.in: Implement --with-dmalloc.
10617 * acconfig.h: Document WITH_DMALLOC.
10618 * m4.h: Add code for when WITH_DMALLOC.
10620 1994-08-15 François Pinard <pinard@iro.umontreal.ca>
10622 * m4.c (long_options): Use "error-output", the dash was missing.
10623 Reported by Akiko Matsushita.
10625 1994-08-12 François Pinard <pinard@iro.umontreal.ca>
10627 * m4.h: Include <sys/types.h>.
10628 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
10629 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
10630 int.
10631 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
10632 as size_t, not int.
10633 * builtin.c (dump_args): Declare len as size_t, not int.
10635 * debug.c: Prototype the forward declaration of debug_set_file.
10637 * builtin.c (m4_undivert): Replace div by file, for avoiding the
10638 shadowing of this variable.
10639 * output.c (insert_diversion): Idem.
10641 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
10642 (input_init): Duplicate default quote and comment strings.
10643 (set_quotes): Free previous quote strings in all cases. Duplicate
10644 even default quote strings.
10645 (set_comment): Free previous comment strings in all cases.
10646 Duplicate even default comment strings.
10648 * configure.in: Updated for Autoconf 2.0.
10649 * Makefile.in (distclean-local): Also delete config.cache.
10651 * m4.c (usage): Reorganize the --help output by topic. Include a
10652 description for debugging flags.
10654 1994-07-29 François Pinard <pinard@iro.umontreal.ca>
10656 * configure.in: If sigaction is available and SA_ONSTACK defined,
10657 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
10658 defined, use sigvec. Else don't compile stackovf.c.
10659 * stackovf.c (setup_stackovf_trap): Idem.
10660 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
10661 and Simon Leinen.
10663 1994-07-21 François Pinard <pinard@iro.umontreal.ca>
10665 * m4.c (usage): Replace printf par fputs.
10666 \f
10667 1994-07-18 François Pinard <pinard@iro.umontreal.ca>
10669 * Release 1.2
10671 1994-07-17 François Pinard <pinard@iro.umontreal.ca>
10673 * configure.in: Check for sigaction and sigvec. Add a new delayed
10674 check for RLIMIT_STACK, combine in the checking for getrlimit.
10675 All those things are not universally available.
10676 * stackovf.c: Split setting up the trap handler and catching
10677 signals, for better taking care of various configure outcomes.
10678 * examples/stackovf.sh: Correct a typo.
10679 Reported by Eric Backus, Jim Avera and Jim Meyering.
10681 1994-07-16 François Pinard <pinard@iro.umontreal.ca>
10683 * ansi2knr.c: New version sent by its author, Peter Deutsch.
10685 1994-07-15 François Pinard <pinard@iro.umontreal.ca>
10687 * Makefile.in: Modify so parallel make will not try making
10688 lib/libm4.a twice simultaneously.
10689 Reported by Jim Meyering.
10691 1994-07-14 François Pinard <pinard@iro.umontreal.ca>
10693 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
10694 error message, for when no code possibility exists. Even if this
10695 line is completely #ifdef'ed out, it brings a syntax error.
10696 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
10698 * Makefile.in (install): Have install depend on all too, for lib
10699 to be remade as needed.
10701 * examples/stackovf.sh: Try ksh, bsh and bash for shells
10702 providing ulimit, instead of using only ksh.
10703 Reported by Jim Avera and Joseph E. Sacco.
10705 1994-07-12 François Pinard <pinard@iro.umontreal.ca>
10707 * Makefile.in (check): Have it depend on all instead of m4. In
10708 this way, a change in lib will be detected and processed.
10710 * builtin.c (numeric_arg): Use strtol and verify the conversion,
10711 instead of using sscanf which stops as soon as there is a
10712 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
10713 and divert(1xyzzy) were all accepted without any warning or error
10714 messages.
10715 * m4.h: Declare strtol as long if not including stdlib.h.
10716 * configure.in: Check for limits.h, and replace strtol if missing.
10717 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
10718 * lib/strtol.c: New file, from elsewhere.
10719 Reported by Andreas Schwab.
10721 1994-07-07 François Pinard <pinard@iro.umontreal.ca>
10723 * macro.c (expand_macro): Cast value to (boolean) prior to
10724 assigning it to traced.
10725 Reported by Tom McConnell.
10727 * Makefile.in (m4): Always make all in lib first.
10728 Reported by Jim Meyering.
10730 1994-07-06 Jim Avera <jima@netcom.com>
10732 * stackovf.c: Isolated OS-dependent sections; Improved portability,
10733 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
10734 handlers), and a default error message if the fault address is not
10735 available (when neither siginfo.h nor BSD sigcontext are supported).
10736 * configure.in: Changes for stackovf.h: Check for sigcontext,
10737 sigaction, sigstack, and define rlim_t as int if necessary.
10738 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
10739 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
10740 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
10742 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
10744 * configure.in: Use AC_SET_MAKE.
10745 * Makefile.in: Use @SET_MAKE@.
10746 Reported by Jim Meyering.
10748 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
10749 Reported by Ian Taylor.
10751 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
10753 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
10754 because siginfo.h is unrelated to standard headers, and siginfo.h
10755 is already checked for.
10756 Reported by Joseph E. Sacco.
10758 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
10759 PROTOTYPES.
10760 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
10761 AC_PROTOTYPES.
10763 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
10765 * builtin.c (substitute): Use \& to represent this part of the
10766 string which was matched by the whole regexp, instead of
10767 representing the whole string. Any usage of \0 issues a warning
10768 and acts like \&, it will disappear in some subsequent release.
10770 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
10772 * m4.c: Complete prototype for forwarded declaration of usage.
10774 * input.c (init_macro_token): Correct own reference in error
10775 message. Previous name get_macro_func was referred to instead.
10776 (next_char): Correct own reference in error message. Previous
10777 name advance_input was referred to instead.
10779 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
10780 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
10781 and_term, not_term, logical_not_term, cmp_term, shift_term,
10782 add_term, mult_term, exp_term, unary_term, simple_term): Add
10783 prototype to forwarded declarations. Declare parameter v1 as
10784 eval_t * instead of int *. Same for local variable v2 in dyadic
10785 functions. Same for result in exp_term.
10786 * builtin.c (m4_eval): Declare value as eval_t instead of int.
10787 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
10788 unsigned_eval_t instead of unsigned int. Change casts accordingly.
10789 (shipout_int): Cast first argument of ntoa to eval_t.
10790 Reported by Thorsten Ohl.
10792 * macro.c: Complete the prototypes of forwarded expand_macro and
10793 expand_token.
10794 Reported by Thorsten Ohl.
10796 * m4.h: Define voidstar as void * or char * depending on __STDC__.
10797 The Ultrix 3.1 compiler cannot do much with void pointers.
10799 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
10800 * m4.c (xfree): Replace void * by voidstar.
10801 Reported by Tom McConnell.
10803 * ansi2knr.1: New, from elsewhere.
10804 * Makefile.in (DISTFILES): Distribute ansi2knr.1
10806 * Makefile.in (stamp-h.in): Avoid running ./config.status if
10807 stamp-h does not exist yet. This avoids running it a second time
10808 just after the initial ./configure.
10809 Reported by David MacKenzie and Tom McConnell.
10811 * m4.h: Replace the enum debug_info declaration with a series of
10812 #define's. The Ultrix 3.1 compiler would otherwise need casting
10813 (int) to most references, when used in expressions.
10814 Reported by Tom McConnell.
10816 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
10818 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
10819 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
10820 calls the compiler. Previously, FP_PROTOTYPES was only calling
10821 the preprocessor; by not being subject to CFLAGS, this was
10822 discouraging those flags asking for ANSI compilation.
10823 * acconfig.h: Document HAVE_PROTOTYPES.
10824 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
10825 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
10826 Reported by Eric Backus.
10828 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
10829 from the environment. Default CFLAGS to -g if not set.
10830 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
10831 * lib/Makefile.in: Have CFLAGS substituted from configure.

10901 is exceeded.
10902 Reported by Bengt Mertensson.

10905 Things like `eval(08)' used to return 0 with no diagnostic.
10907 * m4.h: Capitalize first letter of all macro arguments in
10908 definitions.
10910 * m4.c: Declare warning_status, initialize it to 0. Add new

10926 1994-06-22 François Pinard <pinard@iro.umontreal.ca>
10928 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
10929 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
10930 also tested it on a Sun Sparc workstation running SunOS 4.x.
10932 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
10933 49.format check, abusing a `union values' argument with sprintf
10934 without selecting the proper field. Now, save the formatting type
10935 first, delaying the fetch of the corresponding argument.
10936 Reported by Joseph E. Sacco and Tom Quinn.
10938 * format.c (format): Remove const from char *fmt declaration when
10939 not HAVE_EFGCVT, because a NUL may be forced into it.

10942 Reported by Joseph E. Sacco.
10944 * Regenerate configure using Autoconf 1.11, this corrects a

10978 Reported by Jim Meyering and Joseph E. Sacco.
10980 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
10981 of `if ... else /* nothing */' for if macros.
10982 Reported by Jim Meyering.
10984 * builtin.c (m4_regexp): Reorganize the code for avoiding a
10985 warning from gcc about `repl' possibly used before defined.
10986 Reported by Jim Meyering.
10988 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
10989 Reported by Jim Meyering.
10991 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
10993 * m4.h: Move the conditional definition of volatile after the
10994 inclusion of system files, because they may define it first.
10996 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
10998 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
10999 get around a problem with Alpha make seeing a syntax error, there.
11000 Reported by Vern Paxson.
11002 1994-01-03 François Pinard <pinard@iro.umontreal.ca>

11015 * m4.c: Initialize show_help and show_version to zero.
11017 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
11018 Use them in exit() and usage() calls.
11020 1993-11-27 François Pinard <pinard@iro.umontreal.ca>
11022 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
11023 syserr() macro. Delete errref, add reference_error and M4ERROR.
11024 * m4.c: Replace errref, which was returning an input reference
11025 string, with reference_error, which prints it on standard error.
11026 * builtin.c, output.c: Use errno as second parameter to error,
11027 instead of using syserr() with %s.
11028 * *.c: Use M4ERROR instead of error: no more errref() with %s.
11029 Doing so, the program name appears after the input reference
11030 instead of before, which eases M-x next-error processing.
11032 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
11034 * checks/get-them: Escape braces with backslashes in patterns,

11045 * m4.c: Delete error_message_prefix() function, add errref().
11046 * *.c: Use error() systematically in place of all error macros,
11047 now that error() flushes stdout first. Make needed adjustments.
11049 * m4.h: Remove const in sys_errlist[] declaration, it creates
11050 conflicts on SGI and Alpha.
11051 Reported by Kaveh R. Ghazi.
11053 1993-11-20 François Pinard <pinard@iro.umontreal.ca>

11058 * acconfig.h: New, for documenting HAVE_EFGCVT.
11059 * Makefile.in: Distribute acconfig.h, .stamp-h.in and config.h.in,
11060 use them wherever appropriate. Also use -I. for compilations.

11069 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
11071 * input.c (input_init): Initialize quote and comment strings
11072 explicitely instead of calling set_quotes and set_comment: by
11073 doing so, we ensure we do not free uninitialized variables.
11075 * checks/check-them: Reverse arguments to both diff, so the
11076 expected is on the left and the obtained on the right.
11078 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
11079 macros. Delete declarations for m4error, warning, fatal and
11080 internal_error, add declaration for error_message_prefix.
11081 * m4.c: Delete m4error, warning, fatal and internal_error
11082 routines, add error_message_prefix routine.
11083 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
11084 warning with WARNING*, fatal with FATAL* and internal_error with
11085 INTERNAL_ERROR*.
11086 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
11087 this is not needed anymore.
11089 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
11090 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
11091 and debug_message, add declaration for debug_message_prefix.
11092 * debug.c: Remove static specifier for FILE *debug declaration.
11093 Delete debug_print and debug_message routines, add
11094 debug_message_prefix routine.

11102 (trace_format): Use stdarg instead of varargs if __STDC__.
11104 * configure.in: Remove checks for vfprintf and _doprnt. These
11105 implementations use varargs tricks which are not portable enough.
11106 * lib/vfprintf.c: Deleted.
11107 * lib/_doprnt.c: Deleted.
11108 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.

11328 1993-01-17 François Pinard <pinard@iro.umontreal.ca>
11330 * Makefile.in, lib/Makefile.in: Put $(CFLAGS) after $(CPPFLAGS),
11331 so the installer can override automatically configured choices.
11332 Reported by Karl Berry.
11334 1993-01-15 François Pinard <pinard@iro.umontreal.ca>
11336 * lib/vfprintf.c: Stolen from Oleo distribution and adapted. The
11337 previous version was not working properly on m68k-hp-bsd4.3.
11338 Reported by Roland McGrath.
11340 * lib/_doprnt.c: Stolen from Oleo distribution.
11341 * configure.in: Check for _doprnt.c if vfprintf.c selected.
11342 * lib/Makefile.in: Distribute _doprnt.c.
11343 Do not distribute regex.[ch].old anymore.
11345 1993-01-01 François Pinard <pinard@iro.umontreal.ca>
11347 * Makefile.in, lib/Makefile.in: Reinstate $(CPPFLAGS), use it.
11348 Richard wants it there.
11350 1992-12-27 François Pinard <pinard@iro.umontreal.ca>
11352 * Makefile.in: Add DEFS to MDEFINES.
11353 * lib/Makefile.in (.c.o): Remove $(CPPFLAGS).
11354 (libm4.a): Remove the library before creating it.
11355 (distclean): Remove tags and TAGS too.
11357 1992-12-23 François Pinard <pinard@iro.umontreal.ca>
11359 * Makefile.in (dvi, m4.dvi): New goals.
11361 * builtin.c, eval.c, format.c, input.c, m4.[ch], m4.texinfo,
11362 macro.c, output.c, path.c, symtab.c: Change Copyright from
11363 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
11365 * examples/divert.m4: Deleted, this bug has been corrected.
11367 * Makefile.in (texclean, mostlyclean): New goals.
11369 * Makefile.in (clean): Remove clutter from ansi2knr.
11370 Reported by Pierre Gaumond.
11372 1992-12-20 François Pinard <pinard@iro.umontreal.ca>
11374 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
11375 might well use CFLAGS is s/he needs it.
11377 * Makefile.in: Allow installation of info files from a separate
11378 build directory.
11379 Reported by Jason Merrill.
11380 Reported by David MacKenzie.
11381 Reported by Skip Montanaro.
11382 Reported by Erez Zadok.
11383 Reported by Assar Westerlund.
11384 \f
11385 1992-12-19 François Pinard <pinard@iro.umontreal.ca>
11387 * Release 1.0.3
11388 This is still a beta release for the future GNU m4 version 1.1.
11390 * lib/alloca.c: New, from elsewhere.
11391 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
11393 * m4.h: Do not define index/rindex if already defined. If
11394 FALSE/TRUE are already defined, do not redefine them, but merely
11395 define boolean typedef to int.
11397 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
11398 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
11399 because some C compilers do not like connectives with #ifdef.
11400 * m4.h: Define `volatile' only if __GNUC__, instead of once for
11401 __GNUC__ and once for __STDC__.
11402 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
11404 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
11405 Makefile dependencies. Without it, make keeps destroying and
11406 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
11408 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
11409 to diversion/DIVERSION, this was a spelling error.
11411 * m4.c: Declare version[], remove #include "version.h".
11412 * version.h: Deleted.
11413 * Makefile.in: Remove references to version.h.
11415 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
11416 production, by using a simpler and more robust algorithm. This
11417 solves the problem of synclines sometimes written in the middle of
11418 an output line. Delete sync_line() and output_lines variable.
11419 * m4.h: Remove sync_line prototype and output_lines declaration.
11420 * input.c (next_char), output.c (shipout_text): Remove references
11421 to output_lines.
11422 * input.c (push_file, pop_file): Merely put the value -1 in
11423 output_current_line instead of calling sync_line, for delaying a
11424 single `#line NUM FILE' before next output line. Do not test
11425 for sync_output, because this is unnecessary clutter.
11426 * output.c (make_divertion, insert_divertion): Idem.
11427 * input.c: Rename must_advance_line to start_of_input_line, for
11428 consistency.
11430 * debug.c (trace_header): Select a new debug line format, which
11431 better complies with GNU standards for formatting error messages.
11432 With option `-dfl', M-x next-error might be used on the output.
11433 * m4.c (vmesg): Adjust format of error output to GNU standards.
11434 * m4.texinfo: Adjust examples for `make check' to work.
11436 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
11437 case for enum debug_info constants, which were all lower case.
11439 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
11440 re_search_2.
11441 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
11442 collected patches. I tried a few times using newer regex.[ch], it
11443 mysteriously stopped aborting with this one. Insecure feeling...
11444 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
11446 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
11448 * m4.c: Change `--no-warnings' to `--silent'.
11449 Reported by David MacKenzie.
11451 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
11452 leave it off for now. See comment in m4.c for justification.
11453 Reported by David MacKenzie.
11455 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
11456 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
11458 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
11460 * Makefile.in: Ensure recursive cleaning is done before local
11461 cleaning for all clean goals.
11463 * builtin.c (ntoa): Ensure the value is always interpreted as a
11464 signed quantity, whatever the radix is.
11466 1992-11-18 Jim Meyering <meyering@idefix>
11468 * builtin.c, format.c, input.c: Split long lines.
11469 * m4.c: Use typedef macro_definition instead of struct
11470 macro_definition.
11471 * symtab.c: Use typedef symbol instead of struct symbol.
11473 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
11475 * *.[ch]: Remove all trailing whitespace, in code and comments.
11477 * configure.in: Find some awk.
11478 * Makefile.in: Add $(AWK) to MDEFINES.
11479 * checks/Makefile.in: Transmit $(AWK) to get_them.
11480 * checks/get_them: Use $AWK instead of gawk. Add a close in the
11481 awk script when switching files, because without this, mawk runs
11482 out of file descriptors.
11484 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
11486 * Makefile.in (realclean): Delete m4.info*.
11487 Reported by Jim Meyering.
11489 * Makefile.in: Adjust and link with checks/Makefile.
11490 * checks/Makefile.in: New.
11491 * configure.in: Output checks/Makefile.
11493 * checks/get_them: Have the dnl header of each test more
11494 recognizable by next-error, also use a better message.
11496 1992-11-16 Jim Meyering <meyering@idefix>
11498 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
11499 And use that only if __GNUC__ since we're using it's GCC-specific
11500 semantics that tell the compiler the associated function doesn't
11501 return.
11503 * builtin.c (substitute): Don't use character as an array index.
11504 (dumpdef_cmp): Make formal arguments `const void *' to avoid
11505 warnings with gcc -W -Wall on systems with qsort prototype.
11506 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
11507 from gcc -W -Wall.
11509 * eval.c (most functions): Add parentheses to assignments used
11510 as truth values go avoid warnings from gcc -Wall.
11512 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
11513 any functions that don't need external scope.
11515 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
11516 (many functions and arrays): Declare `const'.
11518 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
11520 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
11521 removing the declaration from m4.h. Also rename false to FALSE
11522 and true to TRUE.
11524 * lib/Makefile.in (Makefile): New goal.
11526 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
11527 so heavily loaded. It gets more easily overridable, calling make.
11528 Reported by Jim Meyering.
11530 * Makefile.in (dist): Get .fname from the current directory name,
11531 instead of from version.h. I need updating many files manually,
11532 when the version changes, version.h is just one of them.
11534 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
11536 * m4.h: Remove the tag `boolean' on the enum introducing typedef
11537 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
11538 Reported by Tom McConnell.
11540 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
11542 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
11543 39.cleardiv, which were describing missing or spurious newlines.
11544 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
11545 do not depend on machine word size, `/bin/false' implementation,
11546 or `wc' output format. `make check' is more dependable, now.
11548 * checks/check_them: Summarize the failed tests by listing their
11549 name, at end. If none, issue `All checks successful'. Output
11550 `Checking' instead of `Input file:'.
11552 * checks/get_them, checks/check_them: Reindented.
11554 * Makefile.in (dist): chmod a+r before making the tar file.
11556 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
11558 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
11560 * input.c (next_token): Reinitialize token_buttom just after using
11561 it as a watermark with obstack_free. Or else, a future token, big
11562 enough for triggering reallocation of the obstack chunk, could
11563 void the initialized value of token_buttom, later causing panic in
11564 obstack_free. Rename token_buttom to token_bottom everywhere.
11566 * m4.h: Before declaring errno, first include <errno.h> and
11567 ensure that it does not define errno.
11568 Reported by Richard Stallman.
11570 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
11572 * builtin.c: Define and use DECLARE macro for builtins.
11574 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
11575 argument, this is a common idiom for introducing long comments.
11577 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
11578 arguments. The last argument was silently ignored.
11580 * m4.c (cmd_error): Add a missing semicolon before va_end().
11582 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
11584 * Makefile.in: Now handle protoized sources. Define and use U.
11585 Compile and use ansi2knr with old compilers. Update DISTFILES.
11586 Add `aclocal.m4' to `configure' dependencies.
11587 * ansi2knr.c: New, from Ghostscript distribution.
11588 * configure.in: Define U through FP_PROTOTYPES for old compilers.
11589 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
11590 * aclocal.m4: New, provide FP_PROTOTYPES.
11591 * m4.h: Conditionnaly protoized through Args, save for varags.
11592 * builtin.c: Protoized. Then:
11593 Include <sys/types.h> if size_t is not defined, before "regex.h".
11594 (m4_ifelse): Fetch built-in name properly for diagnostic.
11595 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
11596 (m4_regexp): Add const to `msg' declaration.
11597 (m4_patsubst): Add const to `msg' declaration.
11598 * debug.c: Protoized, save for varargs.
11599 * eval.c: Protoized.
11600 * format.c: Protoized.
11601 * input.c: Protoized.
11602 * m4.c: Protoized, save for varargs. Then:
11603 (xfree): Accept void * instead of char *.
11604 (xmalloc): Return void * instead of char *.
11605 (xrealloc): Accept and return void * instead of char *.
11606 * macro.c: Protoized.
11607 * output.c: Protoized.
11608 * path.c: Protoized. Then cast some (char *) over xmalloc's.
11609 * symtab.c: Protoized.
11611 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
11613 * m4.texinfo: Remove directory from diagnostics in 30.include,
11614 51.eval, 56.errprint and 57.m4exit tests.
11616 * m4.h: Remove declarations for int or void system functions, they
11617 cause more conflicting trouble than they make good.
11619 * configure.in: Avoid configuration header file. Add some tests.
11620 * m4.h: Remove #include "config.h".
11621 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
11622 Then, rewritten for better compliance with GNU standards.
11624 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
11626 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
11627 because of a misplaced #endif.
11629 * Many *.[hc] files: Correct intra-line spacing here and there,
11630 according to GNU indent 1.6 advice.
11632 * configure.in: New, using Autoconf 1.2.
11633 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
11634 * Delete old configure.in, configure, etc/configure.in,
11635 etc/configure, lib/configure.in, lib/configure and config/*.
11636 Reported by Jason Merrill.
11638 * symtab.c (hash): Change (char) NULL to '\0'.
11639 Reported by Jason Merrill.
11641 * Delete .vers, etc/newdist.sh, etc/newvers.sh and
11642 etc/nextvers.sh. Release numbers will be edited `by hand'.
11643 * version.h: De-automatize, force value in.
11645 * m4.c: Changes in order to use a newer getopt.h.
11646 Reported by David MacKenzie.
11648 * checks/: New name for examples/.
11649 * checks/get_them: New location for etc/get_examples.
11650 * checks/check_them: New location for etc/check_examples.
11651 * Makefile.in, checks/get_them, checks/check_them: Adjust.
11652 * lib/vfprintf.c: New location for etc/vfprintf.c.
11653 * Delete empty etc/.
11654 * examples/: New name for test/.
11656 1992-03-10 François Pinard <pinard@iro.umontreal.ca>
11658 * Makefile.in (check): Add m4 as dependency.
11660 * m4.c: Accept --no-warnings instead of --no_warnings, and
11661 --no-gnu-extensions instead of --no_gnu_extensions. Make the
11662 usage message more informative.
11663 Reported by David MacKenzie.
11665 1992-03-09 François Pinard <pinard@iro.umontreal.ca>
11667 * etc/check_examples: New name for check_examples.sh.

11674 code disposition by hand.
11676 1992-03-08 François Pinard <pinard@iro.umontreal.ca>
11678 * m4.h: Delete definitions for abort() and exit().
11679 Reported by Richard Stallman.
11681 * config/hmake-unicos, config/s-unicos.h: New files.
11682 Reported by Hal Peterson.
11684 * eval.c (exp_term): Have N^0 return 1.
11685 Reported by Michael Fetterman.

11695 reports and feedback.
11697 * Uses GNU configure, taken from the gdb distribution.
11699 * Uses GNU getopt(), with long option names.
11701 * The -Q/+quiet option is added, which suppresses warnings about
11702 missing or superflous arguments to built-in macros.
11704 * Added default options via the M4OPTS environment variable.
11706 * The built-in format can now be configured to use sprintf as
11707 the formatting engine, for systems without [efg]cvt(3).
11709 * GNU library code is moved to the ./lib subdirectory; other
11710 utility files are now in ./etc.
11712 * Several minor bugs have been fixed.
11713 \f
11714 1991-07-26 René Seindal <seindal@diku.dk>
11716 * Fixed various bugs. Release 0.99, manual 0.09. Many thanks to
11717 François Pinard and Roland H. Pesch for providing me with reports.
11719 * The builtins incr and decr are now implemented without use of
11720 eval.
11722 * The builtin indir is added, to allow for indirect macro calls
11723 (allows use of "illegal" macro names).
11725 * The debugging and tracing facilities has been enhanced
11726 considerably. See the manual for details.
11728 * The -tMACRO option is added, marks MACRO for tracing as soon
11729 as it is defined.
11731 * Builtins are traced after renaming iff they were before.
11733 * Named files can now be undiverted.
11735 * The -Nnum option can be used to increase the number of
11736 divertions available.
11738 * Calling changecom without arguments now disables all comment
11739 handling.
11741 * The function m4_patsubst() is now consistently declared
11742 static.
11744 * A bug in dnl is fixed.
11746 * A bug in the multi-character quoting code is fixed.
