1117 2008-05-08 Eric Blake <ebb9@byu.net>
1119 Stage 23: allow tracing of indirect macro calls.
1120 Track all trace information as part of the argv struct, rather
1121 than temporarily resetting global state. Teach indir to trace
1122 macros that it invokes.
1123 Memory impact: slight penalty, due to larger argv struct.
1124 Speed impact: none noticed.
1125 * m4/m4module.h (m4_input_block): Remove.
1126 (m4_call_info): New opaque type.

1171 Stage 22: allow builtin token concatenation outside $@.
1172 Adjust the input and argument parsing engines to append builtins
1173 alongside text. Make define warn when builtins must be
1174 flattened.

1176 Speed impact: slight penalty, from more bookkeeping.
1177 * m4/m4module.h (m4_is_arg_composite): New prototype.
1178 (m4_symbol_value_copy): Change return type.

1279 * tests/null.out: Check for esyscmd failure.
1280 Reported by Elbert Pol.
1282 2008-04-14 Eric Blake <ebb9@byu.net>
1284 Stage 21b: $@ concatenates builtins, m4wrap takes builtins.
1285 Improve arg_print to handle builtin tokens when printing to a
1286 known chain, rather than always flattening builtins. This allows
1287 m4wrap and $@ back-references to handle embedded builtin tokens.
1288 Memory impact: none.
1289 Speed impact: slight penalty, from more bookkeeping.
1290 * m4/m4module.h (m4_push_builtin): Add parameter.
1291 (m4_builtin_print, m4_push_wrapup_init, m4_push_wrapup_finish)
1292 (m4_arg_print, m4_symbol_value_print): Rename and reduce scope...
1293 * m4/m4private.h (m4__builtin_print, m4__push_wrapup_init)
1294 (m4__push_wrapup_finish, m4__arg_print, m4__symbol_value_print):

1318 * modules/gnu.c (builtin): Likewise.
1319 * doc/m4.texinfo (M4wrap): New test.
1320 (Debuglen): Adjust expected output.
1322 Stage 21a: Optimize checks for end of input.
1323 Create a new polymorphic input block type, which always fails with
1324 CHAR_EOF, so that remaining input routines no longer have to check
1325 for NULL input block.
1326 Memory impact: none.
1327 Speed impact: noticeable improvement, from fewer conditionals.
1328 * m4/input.c (eof_funcs, input_eof): New objects.
1329 (eof_peek, eof_read, eof_unget): New functions.
1330 (file_clean, m4_push_string_init, pop_input, m4_push_wrapup_init)
1331 (m4_pop_wrapup, next_char, peek_char, unget_input, m4_input_init)
1332 (m4_input_exit): Use placeholder to guarantee non-NULL isp and

1338 * modules/gnu.c (m4_macro_table): Ensure all possible identifiers
1339 are defined, not just the first. The testsuite ensures that
1340 exactly one gets defined.

1342 what other pre-defined macros it has.
1343 * THANKS: Update.
1344 Reported by Elbert Pol.
1346 Ensure __m4_version__ is unquoted.

1359 * tests/others.at (ifndef): New test.
1361 Be namespace clean for M4 version; fixes 2008-04-08 regression.
1362 * configure.ac (version): Rename...
1363 (M4_VERSION): ...to this, since using 'version' broke po.m4.
1365 2008-04-09 Eric Blake <ebb9@byu.net>

1374 2008-04-08 Eric Blake <ebb9@byu.net>
1376 Overhaul inter-version releases to work with git.
1377 * configure.ac (version): New variable, which has nicer version
1378 contents when using git 1.5.5+, hardcoded to 1.9a otherwise.
1379 (TIMESTAMP): Delete, since CVS id expansion died with transition
1380 to git.
1381 (AM_INIT_AUTOMAKE): Use version to decide gnu vs. gnits.
1382 * build-aux/mkstamp: Delete, no longer used.
1383 * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Kill, to speed up

1386 (EXTRA_DIST): No longer worry about mkstamp.
1387 (.version): New rule and distributed file.
1388 (doc/m4.1, tests/package.m4): Depend on .version, not
1389 configure.ac, for timestamp.
1390 * ltdl/m4/gnulib-cache.m4: Import git-version-gen module.
1391 * modules/gnu.c (__m4_version__): TIMESTAMP no longer exists.

1403 Stage 20b: make m4wrap obey POSIX fifo ordering.
1404 Improve input engine to support location changes within symbol
1405 chains, then convert m4wrap to always build symbol chain.
1406 Memory impact: none.
1407 Speed impact: slight penalty, from more m4wrap bookkeeping.
1408 * m4/m4module.h (m4_wrap_args): Add prototype.
1409 * m4/m4private.h (enum m4__symbol_chain_type): Add M4__CHAIN_LOC.

1419 (Location, Improved m4wrap): Adjust example to match FIFO order.
1420 * tests/builtins.at (wrap): Likewise.
1421 * NEWS: Document this change.
1423 2008-03-17 Eric Blake <ebb9@byu.net>
1425 Stage 20a: reduce unget's in input engine.
1426 Now that out-of-range input placeholders like CHAR_BUILTIN are
1427 consumed outside of next_char, next_token should always consume
1428 rather than peek at the first character. Fewer peeks results in
1429 less ungetc overhead.
1430 Memory impact: none.
1431 Speed impact: noticeable improvement, from fewer function calls.
1432 * m4/input.c (struct input_funcs): Alter read_func prototype.
1433 (next_char, file_read, buildin_read, string_read, composite_read):
1434 Add allow_argv parameter.
1435 (init_builtin_token, init_argv_symbol): Require all prior input to
1436 be consumed.
1437 (m4_skip_line, match_input, consume_syntax): Adjust callers.
1438 (m4__next_token): Consume first byte without peek.
1440 Update for fresh bootstrap.
1441 * ltdl/m4/gnulib-cache.m4: Updated copyright from upstream.
1443 2008-03-15 Eric Blake <ebb9@byu.net>
1445 Document join, in order to fix bug in m4wrap example.
1446 * examples/join.m4: New file.
1447 * examples/wraplifo2.m4: Likewise.
1448 * Makefile.am (EXTRA_DIST): Add new files.
1449 * doc/m4.texinfo (Improved m4wrap): New node.
1450 (Defn, Location): Enhance tests.
1451 (Shift): Document the composite macro join.
1452 (Incompatibilities): Move documentation of LIFO vs. FIFO...
1453 (M4wrap): ...here, to match improved example.
1455 2008-03-13 Eric Blake <ebb9@byu.net>
1457 Stage 19c: allow builtin tokens in more macros.
1458 Allow builtin tokens inside symbol chains, although for now, they
1459 are not allowed inside comments or quotes. Enable builtin token
1460 handling in more macros, if only to consistently diagnose invalid
1461 macro names.
1462 Memory impact: none.
1463 Speed impact: slight impact, due to more bookkeeping.
1464 * m4/m4module.h (m4_symbol_value_lookup, m4_builtin_print): New
1465 prototypes.
1466 * m4/m4private.h (enum m4__symbol_chain_type): Add
1467 M4__CHAIN_FUNC.
1468 (struct m4__symbol_chain): Add builtin member.

1473 (m4__push_symbol): Allow pushing builtin tokens.
1474 (composite_peek, composite_read, composite_unget, composite_clean)
1475 (composite_print): Handle builtin tokens.
1476 (init_builtin_token): Allow builtin tokens from composite input.
1477 (m4__next_token): Flatten builtins inside comment or string.
1478 * m4/macro.c (expand_argument): Strengthen assertion.
1479 (collect_arguments, m4_arg_equal, m4_arg_print, m4_push_args):
1480 Handle builtin tokens.
1481 (arg_symbol): Add parameter, and allow NULL level.
1482 (m4_arg_symbol, m4__push_arg_quote): Adjust callers.
1483 (m4_arg_text): Ensure all builtins have been flattened.
1484 * modules/m4.c (defn, dumpdef, popdef, traceoff, traceon)
1485 (undefine, m4_dump_symbols): Warn on invalid macro names.
1486 (ifdef, ifelse, shift): Handle builtin tokens.
1487 * modules/gnu.c (m4symbols): Likewise.
1488 * doc/m4.texinfo (Defn, Ifdef, Ifelse): Document and test the new
1489 behavior.
1490 (Debuglen): Likewise, and remove xfail.
1491 * NEWS: Mention the change.
1493 Stage 19b: invert sense of bit for handling builtin tokens.
1494 Pass builtin tokens by default, rather than as the exception, so
1495 that the logic can consistently refer to flattening arguments.
1496 Memory impact: none.
1497 Speed impact: none.
1498 * m4/m4module.h (M4BUILTIN_ENTRY): New convenience macro.
1499 (M4_BUILTIN_GROKS_MACRO): Rename...
1500 (M4_BUILTIN_FLATTEN_ARGS): ...and invert sense.
1501 (m4_symbol_value_groks_macro, m4_symbol_groks_macro): Likewise...
1502 (m4_symbol_value_flatten_args, m4_symbol_flatten_args): ...to
1503 this.
1504 * m4/m4private.h (VALUE_MACRO_ARGS_BIT)
1505 (m4_symbol_value_groks_macro): Likewise...
1506 (VALUE_FLATTEN_ARGS_BIT, m4_symbol_value_flatten_args): ...to
1507 this.
1508 * m4/symtab.c (m4_symbol_value_groks_macro): Likewise...
1509 (m4_symbol_value_flatten_args): ...to this.
1510 * m4/macro.c (collect_arguments): Accomodate changed sense.
1511 * m4/module.c (m4__module_open): Require arguments if flattening
1512 is requested.
1513 * m4/input.c (m4_push_string_finish): For now, flatten all
1514 builtins pushed as back-references.
1515 * modules/gnu.c (m4_builtin_table, builtin): Adjust all clients.
1516 * modules/import.c (m4_builtin_table): Likewise.
1517 * modules/load.c (m4_builtin_table): Likewise.
1518 * modules/modtest.c (m4_builtin_table): Likewise.

1521 * modules/shadow.c (m4_builtin_table): Likewise.
1522 * modules/stdlib.c (m4_builtin_table): Likewise.
1523 * modules/time.c (m4_builtin_table): Likewise.
1524 * modules/m4.c (m4_builtin_table): Likewise.
1525 (mkstemp): Undo #undef hack from 2006-10-23, now that macro names
1526 are stringized without preprocessor expansion.
1527 * doc/m4.texinfo (Defn): Update comments to match reality.
1528 (Debuglen): Update test now that user macros pass builtin tokens.
1530 Stage 19a: sort and cache builtins loaded by a module.
1531 Rather than repeatedly using dlsym to browse the builtin table,
1532 copy off the table at module load time. Then, the input engine
1533 merely refers to the copy instead of duplicating information.
1534 Memory impact: slight penalty, due to more memory per module, but
1535 offset by less memory in input engine.
1536 Speed impact: slight improvement, due to faster builtin lookups.
1537 * m4/m4module.h (m4_set_symbol_value_builtin): Delete. Use
1538 m4_builtin_find_by_* instead.
1539 (m4_builtin_find_by_func): Change return type.
1540 * m4/m4private.h (m4__builtin): New struct.
1541 (m4_module): Add sorted list of loaded builtins.
1542 (struct m4_symbol_value): Change type of builtin value.
1543 (m4__set_symbol_value_builtin): New prototype and fast accessor.
1544 (m4_get_symbol_value_func, m4_get_symbol_value_builtin): Adjust to
1545 new field type.
1546 * m4/symtab.c (m4_set_symbol_value_builtin): Rename...
1547 (m4__set_symbol_value_builtin): ...and populate additional fields,
1548 based on new type.
1549 (m4_get_symbol_value_func, m4_get_symbol_value_builtin): Adjust to
1550 new field type.
1551 * m4/module.c (install_builtin_table): Use cached table.
1552 (compare_builtin_CB): New helper function.
1553 (m4__module_open): Populate table.
1554 (module_remove): Free table.
1555 * m4/builtin.c (compare_builtin_name_CB): New helper function.
1556 (m4_builtin_find_by_name): Rewrite to use sorted table.
1557 (m4_builtin_find_by_func): Change return type.
1558 * m4/input.c (struct m4_input_block): Simplify u_b, since most
1559 fields can be determined from builtin.
1560 (builtin_peek, builtin_read, builtin_unget, init_builtin_token)
1561 (m4__next_token): Alter parsing so that only init_builtin_token
1562 consumes a builtin.
1563 (builtin_print, m4_push_builtin): Adjust all users.
1564 * tests/macros.at (Arity, defn, and freeze): Fix typo.
1566 Consistently cast malloc results, for C++ compilation.

1581 2008-03-06 Eric Blake <ebb9@byu.net>
1583 Fix nested builtin(`shift',$@) regression from 2008-02-23.
1584 * m4/macro.c (make_argv_ref): Don't output expansion text when
1585 making wrapper for builtin or indir.
1586 * tests/builtins.at (builtin): New test.
1587 * NEWS: Document the fix.
1588 Reported by Andreas Schwab.

1592 The gnulib module free was deprecated.
1593 * ltdl/m4/gnulib-cache.m4: Remove free module.
1595 2008-02-29 Eric Blake <ebb9@byu.net>
1597 Import news from 1.4.10b.
1598 * NEWS: Update from branch.
1600 2008-02-23 Eric Blake <ebb9@byu.net>
1602 Stage 18: try harder to reuse argv in recursion.
1603 When pushing arguments that contain an existing $@ ref, reuse the
1604 ref rather than creating another layer of wrappers.
1605 Memory impact: noticeable improvement, due to better $@ reuse.
1606 Speed impact: noticeable improvement, due to O(n^2) to O(n)
1607 reduction in unboxed recursion.
1608 * m4/macro.c (make_argv_ref): Avoid wrapping $@ when possible.
1609 (m4_push_args): Let make_argv_ref take care of pending data.
1610 * doc/m4.texinfo (Improved foreach): Tweak wording to match new
1611 performance capability.
1612 * tests/others.at (recursion): Add tests to avoid performance
1613 regression.
1615 2008-02-22 Eric Blake <ebb9@byu.net>
1617 Update NEWS.
1618 * NEWS: Document change to __gnu__ on 2008-02-11.
1620 Stage 17: pass argv through quoted strings.
1621 Allow the concatenation of $@ references with other text input
1622 inside quoted contexts, which requires distinguishing between a
1623 wrapper around many arguments vs. a reference serving as part of a
1624 single argument. Also optimize based on whether argv contains
1625 builtin tokens that might need flattening to the empty string.
1626 Memory impact: noticeable improvement, due to O(n^2) to O(n)
1627 reduction from total reuse of $@ references.
1628 Speed impact: noticeable improvement, due to O(n^2) to O(n)
1629 reduction in boxed recursion.
1630 * m4/m4module.h (m4_arg_equal, m4_arg_len): Add parameter.
1631 (M4ARGLEN): Adjust definition.
1632 * m4/m4private.h (struct m4__symbol_chain): Add has_func member.
1633 (struct m4_symbol_value): Add wrapper and has_func members.
1634 (struct m4_macro_args): Add flatten and has_func members.
1635 * m4/input.c (append_quote_token): Return argv refs inside quoted
1636 strings.
1637 (init_argv_symbol): Populate new fields.
1638 * m4/macro.c (expand_argument, collect_arguments, make_argv_ref)
1639 (m4_make_argv_ref): Likewise.
1640 (arg_symbol, arg_mark, m4_is_arg_text, m4_is_arg_func): Use new
1641 fields.
1642 (m4_arg_equal, m4_arg_len): Handle quoted argv references, and add
1643 new parameter.
1644 * modules/m4.c (ifelse): Adjust caller.
1646 2008-02-22 Gary V. Vaughan <gary@gnu.org>
1648 Fix regression in argument collection, from 2008-01-21.
1649 * m4/input.c (m4__next_token): When DEBUG_INPUT is defined,
1650 undo argument collection optimisation for strings, so that
1651 m4_print_token doesn't abort when it otherwise receives an
1652 unprintable M4_SYMBOL_VOID type token.
1654 2008-02-20 Eric Blake <ebb9@byu.net>
1656 Stage 16: cache quotes and improve m4_arg_print.
1657 Cache rather than always copying quotes when pushing $@ refs; in
1658 particular, reconstruct single-byte quotes on the fly. Allow NUL
1659 through m4wrap. Improve sharing of code that prints arguments.
1660 Memory impact: slight improvement, due to cached quotes.
1661 Speed impact: slight improvement, due to less copying.
1662 * m4/m4module.h (m4_symbol_value_print, m4_symbol_print)
1663 (m4_arg_print): Adjust prototypes.
1664 (m4_dump_args): Delete.
1665 (m4_push_wrapup): Split...
1666 (m4_push_wrapup_init, m4_push_wrapup_finish): ...into these
1667 prototypes.
1668 * m4/m4private.h (struct m4_syntax_table): Add cached_quote
1669 member.
1670 (m4__quote_cache, m4__quote_uncache): New prototypes.
1671 * m4/syntax.c (m4_syntax_create): Initialize the cache.
1672 (m4__quote_cache): New function.
1673 (m4_set_syntax): Update caller.
1674 * m4/symtab.c (m4_symbol_value_print): Add parameter.
1675 (m4_symbol_print, dump_symbol_CB): Adjust all callers.
1676 * m4/utility.c (m4_dump_args): Delete; callers should use
1677 m4_arg_print instead.
1678 * m4/input.c (m4_push_wrapup_init, m4_push_wrapup_finish): Split
1679 implementation, and allow embedded NUL.
1680 (m4_print_token, pop_input, composite_print, composite_peek):
1681 (composite_read, append_quote_token): Adjust all callers.
1682 * m4/macro.c (trace_prepre, m4_arg_text, make_argv_ref):
1683 Likewise.
1684 (m4_arg_print): Add parameters.
1685 (trace_pre): Rewrite in terms of m4_arg_print.
1686 * modules/m4.c (errprint): Likewise.
1687 (m4wrap): Rewrite to allow embedded NUL.
1688 (dumpdef): Adjust caller.

1690 * tests/null.m4: Test for NUL in m4wrap.
1691 * tests/null.out: Update expected output.
1693 Fix out-of-bounds read for sanitized macro names, from 2008-02-06.
1694 * m4/utility.c (m4_verror_at_line): Properly terminate the string.
1695 Reported by Ralf Wildenhues.
1697 * doc/m4.texinfo (Debuglen, Changesyntax): Fix typos.
1699 2008-02-19 Eric Blake <ebb9@byu.net>
1701 Clean up example on filtering defined symbols.
1702 * doc/m4.texinfo (Foreach, Improved foreach): Document another
1703 shortcoming in foreach.m4, and improve filter example by using
1704 foreach2.m4.
1706 * src/main.c (usage): Fix typo.
1708 2008-02-18 Eric Blake <ebb9@byu.net>
1710 Avoid some magic numbers.
1711 * m4/m4private.h (CHAR_EOF, CHAR_BUILTIN, CHAR_QUOTE, CHAR_ARGV)

1722 2008-02-16 Eric Blake <ebb9@byu.net>
1724 Add regression test for multi-character quote recursion.

1727 * examples/forloop2.m4: Likewise.
1728 * examples/hanoi.m4: Likewise.
1729 * examples/trace.m4: Likewise.
1730 * doc/m4.texinfo (Improved forloop): Document advantage of $0.
1731 (Improved foreach): Adjust dump from file.
1733 Stage 15: return argv refs back to collect_arguments.
1734 Collect an entire $@ reference at once rather than one argument at
1735 a time, outside of quotes (but inside quotes, $@ is still
1736 flattened for now). The skip_last field allows concatenation of
1737 $@ with other text when collecting arguments.
1738 Memory impact: noticeable improvement, due to better reuse of $@.
1739 Speed impact: noticeable improvement, due to less parsing.
1740 * m4/m4private.h (CHAR_ARGV): New input engine sentinel.
1741 (enum m4__token_type): Add M4_TOKEN_ARGV.
1742 (struct m4__symbol_chain): Add skip_last member to argv link.
1743 (m4__next_token): Add parameter.
1744 * m4/input.c (peek_char, file_peek, builtin_peek, string_peek)
1745 (composite_peek, m4__next_token): Add new parameter.
1746 (composite_read, append_quote_token): Support argv in quotes.
1747 (init_argv_symbol): New function.
1748 (m4__push_symbol, match_input, consume_syntax)
1749 (m4__next_token_is_open, m4_print_token): Adjust callers.
1750 * m4/macro.c (m4_macro_expand_input, m4__arg_adjust_refcount)
1751 (arg_mark, m4_arg_text, make_argv_ref): Likewise.
1752 (expand_argument, collect_arguments): Handle new token.
1753 (arg_symbol): Drill through $@ reference.
1754 * m4/syntax.c (set_quote_age): Detect disabled comments.
1755 * m4/symtab.c (dump_symbol_CB) [DEBUG_SYM]: Fix debug code.
1757 2008-02-15 Eric Blake <ebb9@byu.net>
1759 * modules/gnu.c (regexp_compile): Use a fastmap for regex speed.
1761 2008-02-13 Eric Blake <ebb9@byu.net>
1763 Fix texinfo grammar.
1764 * doc/m4.texinfo (Eval, Incompatibilities): Use @. after capital.
1765 (History): Use @: after abbreviations.
1766 (M4exit): Use correct Latin abbreviation.
1767 (Dumpdef, Debugmode, Frozen file format 2): Use correct spacing
1768 between sentences.
1770 2008-02-11 Eric Blake <ebb9@byu.net>
1772 Allow builtin text macros to specify number of arguments.
1773 * m4/m4module.h (struct m4_macro): Add argument limits to builtin
1774 text macros.
1775 * m4/module.c (install_macro_table): Allow text macros to warn on
1776 extra arguments.

1837 * modules/m4.h (m4_dump_symbols_func): Likewise.
1838 * modules/perl.c (perleval): Likewise.
1840 Stage 14b: allow pushing argv references.
1841 Push a $@ reference to the input engine in one go, rather than
1842 pushing each element. For now, argument collection still gets one
1843 argument of a $@ at a time; but the penalties of this patch make
1844 it easier to manage $@ efficiently in future patches.
1845 Memory impact: noticeable penalty, due to larger struct and O(n)
1846 to O(n^2) on unboxed recursion.

1928 2008-01-27 Eric Blake <ebb9@byu.net>
1930 Stage 13: push composite text tokens.
1931 Support pushing composite tokens, allowing back-references to be
1932 reused through multiple macro expansions. Add hueristic that
1933 avoids creating new reference when pushing existing references.
1934 Memory impact: noticeable improvement due to better reference
1935 reuse, except for O(n) to O(n^2) copying in boxed recursion.
1936 Speed impact: slight penalty, due to more bookkeeping.
1937 * m4/m4private.h (m4__push_symbol): Adjust prototype.

1995 * m4/m4private.h (enum m4__symbol_chain_type): New enum.
1996 (struct m4_symbol_chain): Rename...
1997 (struct m4__symbol_chain): ...to this, since it is internal.
1998 * m4/symtab.c (m4_symbol_value_copy, m4_symbol_value_print): All
1999 callers updated.
2000 * m4/input.c (struct m4_input_block, m4__push_symbol)

2033 example.
2035 2008-01-21 Eric Blake <ebb9@byu.net>
2037 Stage 11: full circle for single argument references.
2038 Pass quoted strings through to argument collection in a single
2039 action, so that an argument can be reused throughout macro
2040 recursion if it remains unchanged.
2041 Memory impact: noticeable improvement, due to more reuse in
2042 argument collection stacks; O(n^2) to O(n) on boxed recursion.
2043 Speed impact: noticeable improvement, due to less copying.
2044 * m4/m4module.h (m4_arg_text): Add parameter.
2045 (M4ARG): Adjust.
2046 * m4/m4private.h (CHAR_QUOTE): New input engine sentinel.

2052 (m4_symbol_value_copy, m4_symbol_value_delete): Recognize
2053 composite tokens.
2054 * m4/input.c (make_text_link): Rename...
2055 (m4__make_text_link): ...to this, and export.
2056 (m4_push_string_finish): Adjust caller.
2057 (make_text_link, m4__push_symbol): Update new field.

2061 (append_quote_token): New function.
2062 (m4__next_token): Pass quoted strings onto argument collection.
2063 (m4_print_token) [DEBUG_INPUT]: Update.
2064 * m4/macro.c (expand_argument): Collect composite arguments.
2065 (collect_arguments): Update new field.
2066 (expand_macro): Reduce ref-count of back-references after use.
2067 (arg_mark, m4_arg_symbol, m4_make_argv_ref): Adjust to new member
2068 names.
2069 (m4_is_arg_text): Also recognize composite symbols as text.
2070 (m4_arg_text, m4_arg_len): Merge composite symbols as needed.
2071 (m4_arg_equal): Compare composite symbols.
2072 (m4_push_arg, m4_push_args): Handle composite symbols.
2073 (m4_arg_symbol): Relax assertion.

2075 * m4/output.c (m4_shipout_string_trunc): Update comment.
2076 * tests/macros.at (Rescanning macros): Augment test.
2078 2008-01-16 Eric Blake <ebb9@byu.net>
2080 Stage 10: avoid extra copying of strings and comments.
2081 When collecting tokens that are immune to further expansion, avoid
2082 copying data from one obstack to another by outputting it into the
2083 destination obstack to begin with. Also reduce copying done in
2084 format builtin.
2085 Memory impact: slight improvement, due to better obstack usage.
2086 Speed impact: noticeable improvement, due less data copying.
2087 * ltdl/m4/gnulib-cache.m4: Import intprops and vasnprintf-posix
2088 modules.
2089 * m4/m4private.h (m4__token_type): Adjust prototype.
2090 * m4/input.c (m4__next_token): Support new parameter.
2091 * m4/macro.c (m4_macro_expand_input, expand_token)
2092 (expand_argument, collect_arguments): Adjust callers.
2093 * modules/m4.c (ntoa): Tighten buffer size.
2094 * m4/output.c (m4_tmpname): Guarantee no buffer overflow.
2095 * modules/format.c (arg_int, arg_long, arg_double): New helper
2096 functions, to detect overflow or unparsed characters.
2097 (ARG_INT, ARG_LONG, ARG_STR, ARG_DOUBLE): Adjust to check for
2098 missing or excess arguments.
2099 (format): Likewise, and also output directly into obstack if there
2100 is room.
2101 * doc/m4.texinfo (History): Update for new year.
2102 (Format): Test for new warnings.
2104 2008-01-15 Eric Blake <ebb9@byu.net>
2106 * TODO: Update with some newer URLs.
2108 Verify linear `index'.
2109 * tests/builtins.at (index): New test.
2110 (translit): Make test take longer, to make quadratic algorithms
2111 more apparent.
2113 2007-12-20 Eric Blake <ebb9@byu.net>
2115 Stage 9: share rather than copy single-arg refs.
2116 Use hooks of previous patch to create back-references to arguments
2117 in the input engine, and inline short text rather than always
2118 creating a FIFO link. Also start testing embedded NUL behavior.
2119 Until the argument collection engine also shares references, the
2120 memory usage increases.
2121 Memory impact: noticeable penalty, due to longer life of argv
2122 changing O(n) to O(n^2) on boxed recursion.
2123 Speed impact: slight improvement, due less data copying.
2124 * ltdl/m4/gnulib-cache.m4: Import memmem and quote modules.
2125 * m4/m4module.h (m4_arg_scratch): New prototype.
2126 * m4/m4private.h (m4__push_symbol): Add parameter.
2127 (m4_arg_scratch): Add fast accessor.
2128 (struct m4): Add expansion_level member, taken...
2129 * m4/macro.c (expansion_level): ...from here. Adjust all users.
2130 (expand_argument): Minor cleanup.
2131 (expand_macro): Track scratch space per macro call.
2132 (m4_arg_scratch): New function.
2133 (m4_make_argv_ref): Call new function.
2134 (m4_push_arg): Push reference to $0.
2135 (m4_push_args): Rework separator usage, since separators will
2136 usually be inlined.
2137 (process_macro): Allow embedded NUL.
2138 * m4/input.c (INPUT_INLINE_THRESHOLD): New define.
2139 (m4__push_symbol): Add parameter. Inline short strings, and save
2140 references through rescanning.
2141 * m4/symtab.c (m4_set_symbol_value_text): Weaken assertion.
2142 * modules/m4.c (errprint, index): Handle NUL transparently.
2143 (dumpdef, translit): Use scratch space, rather than expansion
2144 stack.
2145 * modules/gnu.c (renamesyms, m4symbols): Likewise.
2146 * tests/others.at (nul character): New test.
2147 (iso8859): Quote absolute file name, remove XFAIL.
2148 * tests/iso8859.m4: Avoid raw NUL in output.
2149 * tests/null.m4: New file.
2150 * tests/null.out: Likewise.
2151 * tests/null.err: Likewise.
2152 * Makefile.am (OTHER_FILES): Distribute new files.
2153 * .gitattributes: Treat new files as text.
2155 2007-12-17 Eric Blake <ebb9@byu.net>
2157 Stage 8: extend life of references into argv.
2158 Add hooks to lengthen the lifetime of arguments reused in a macro
2159 expansion, rather than always discarding arguments at the end of
2160 expand_macro. Rework the expand_macro obstacks to handle longer
2161 lifetimes. For now, the hooks remain unused.
2162 Memory impact: slight penalty, due to larger structs.
2163 Speed impact: slight penalty, due to more bookkeeping.
2164 * m4/system_.h (obstack_regrow): Delete.
2165 * m4/m4private.h (struct m4_symbol_chain): Add level field.
2166 (m4__push_symbol): Adjust prototype.
2167 (m4__adjust_refcount): New prototype.
2168 (DEBUG_MACRO) [DEBUG]: New debug control.
2169 (struct m4__macro_arg_stacks): New structure.
2170 (struct m4): Add arg_stacks, stacks_count fields.
2171 * m4/m4module.h (m4_make_argv_ref): Add parameter.
2172 * m4/macro.c (argc_stack, argv_stack): Delete, replaced by
2173 context->arg_stacks.
2174 (m4_macro_expand_input) [DEBUG_MACRO]: Add debug hooks,
2175 conditional on M4_DEBUG_MACRO envvar.
2176 (collect_arguments): Adjust signature.
2177 (expand_macro): Rework obstack handling.
2178 (m4__adjust_refcount, arg_mark): New functions.
2179 (m4_make_argv_ref): Populate new field.
2180 (m4_push_arg, m4_push_args): Track inuse.
2181 (process_macro): One less cast.
2182 * m4/m4.c (m4_delete): Clean up arg_stacks.
2183 * m4/input.c (make_text_link): Use new field.
2184 (m4__push_symbol, file_clean): Update signature.
2185 (composite_read): Bump refcount when done with reference.
2186 (composite_clean): New function.
2187 (pop_input): Adjust caller.
2188 * m4/debug.c (m4_debug_message): Make assertion match comment.
2189 * modules/gnu.c (builtin, indir): Adjust callers.
2190 * tests/builtins.at (ifelse): New test.
2191 (exp): Move and rename...
2192 * tests/others.at (countdown): ...to this.
2193 * doc/m4.texinfo (Improved foreach): Fix tracing usage in
2194 example.
2196 2007-12-13 Eric Blake <ebb9@byu.net>
2198 Yet more rewording.
2199 * doc/m4.texinfo (Inhibiting Invocation): Missed one instance in
2200 the previous patch.
2202 * THANKS: Update.
2204 2007-12-13 Paolo Bonzini <bonzini@gnu.org> (tiny change)
2206 * doc/m4.texinfo (Inhibiting Invocation): Fix quoting of a quoting
2207 example.
2208 Reported by Giovanni Toffetti.
2210 2007-12-11 Eric Blake <ebb9@byu.net>
2212 Stage 7: use chained input support in input parser.
2213 Allow the LIFO input engine to rescan a macro expansion composed
2214 of smaller chunks of FIFO data, rather than the old approach of a
2215 monolithic string. For now, all chunks are still copied.
2216 Memory impact: slight penalty, due to FIFO chain overhead.
2217 Speed impact: slight penalty, due to extra bookkeeping.
2218 * m4/m4private.h (m4__push_symbol): New prototype.
2219 (struct m4_symbol_chain): Add const-safety.
2220 * m4/symtab.c (m4_symbol_value_print): Simplify.
2221 (dump_symbol_CB): Update caller.
2222 * m4/input.c (struct m4_input_block): Alter u_c member, first
2223 introduced 2006-10-25, but unused until now.
2224 (composite_peek, composite_read, composite_unget)
2225 (composite_print, init_builtin_token): Rewrite accordingly.
2226 (m4_push_wrapup): No longer need trailing NUL.
2227 (m4__push_symbol, make_text_link): New functions.
2228 (m4_push_string_finish): Use them.
2229 * m4/macro.c (m4_push_arg, m4_push_args): Likewise.
2230 (expand_macro): Simplify logic of nesting_limit.
2231 * src/main.c (main): Likewise.
2232 * doc/m4.texinfo (Dumpdef): Augment test.
2234 2007-12-08 Eric Blake <ebb9@byu.net>
2236 Stage 6: convert builtins to push arg at a time.
2237 Add new methods to factor all builtins whose expansion includes an
2238 argument, making back-reference creation easier in future patches.
2239 Factor out length-limited printing to obstacks, and use -1 rather
2240 than 0 for unlimited length.
2241 Memory impact: none.
2242 Speed impact: slight improvement, due to better code sharing.
2243 * m4/m4module.h (m4_shipout_text): Rename...
2244 (m4_divert_text): ...to this, to avoid confusion with m4_shipout_*
2245 that does not worry about sync lines.
2246 (m4_shipout_string_trunc): New prototype.
2247 * m4/output.c (m4_shipout_text): Rename...
2248 (m4_divert_text): ...to this.
2249 (m4_shipout_string): Move guts...
2250 (m4_shipout_string_trunc): ...to this new function.
2251 * m4/macro.c (m4_push_arg, m4_push_args): New functions.
2252 (expand_token, process_macro): Update callers.
2253 * m4/input.c (string_print): Likewise.
2254 * modules/m4.c (ifdef, ifelse, shift, substr, translit, divert):
2255 Likewise.
2256 * modules/gnu.c (patsubst): Likewise.
2257 (debuglen): Use SIZE_MAX for unlimited debug length.
2258 * src/main.c (main): Likewise.
2259 * m4/m4.c (m4_create): Default max_debug_length to SIZE_MAX, not
2260 zero.
2262 2007-12-07 Eric Blake <ebb9@byu.net>
2264 Minor security fix: Quote output of mkstemp.
2265 * modules/m4.c (m4_make_temp): Produce quoted output.
2266 * doc/m4.texinfo (Mkstemp, Mkdtemp): Update the documentation and
2267 tests.
2269 Stage 5: add notion of quote age.
2270 Cache the quoting rules that were in effect when a string was
2271 parsed, to avoid reparsing that string if no changequote or other
2272 quote age change took place in the meantime. A quote_age of 0 is
2273 always safe, but does not benefit from caching.
2274 Memory impact: slight improvement, due to smaller struct in input
2275 engine.
2276 Speed impact: slight penalty, due to more bookkeeping.

2325 2007-11-29 Eric Blake <ebb9@byu.net>
2327 Stage 4: route indir, builtin through ref; make argv opaque.
2328 Finish making struct opaque to all but the input engine, by
2329 reworking obstack usage in expand_macro to better support creation
2330 of a $@ reference. Canonicalize the empty argument, to allow
2331 pointer comparison optimizations.
2332 Memory impact: slight penalty, due to larger struct.
2333 Speed impact: slight improvement, due to fewer function calls.
2334 * m4/system_.h (obstack_regrow): Fix precedence.
2335 * m4/m4module.h (m4_arg_equal, m4_arg_empty, m4_make_argv_ref):
2336 New prototypes.
2337 (struct m4_macro_args): Move...
2338 * m4/m4private.h (struct m4_macro_args): ...here, making it opaque
2339 to modules. Add has_ref member.

2359 Stage 3b: cache length, rather than computing it, in modules.
2360 Use cached token length in builtins and output engine.
2361 Memory impact: none.
2362 Speed impact: noticeable improvement, due to fewer function calls.
2363 * m4/hash.c (m4_hash_remove): Avoid double free on remove
2364 failure.
2365 * m4/output.c (m4_shipout_string): Change semantics of len param.
2366 (m4_shipout_int): Use cached length.
2367 * m4/input.c (m4_push_string_finish): Likewise.
2368 * modules/m4.h (m4_make_temp_func): Add parameter.

2387 * tests/builtins.at (mkstemp): Likewise.
2388 * tests/others.at (iso8859): XFAIL this test, now that
2389 length-based handling allows NUL through part but not all of M4.
2391 2007-11-28 Eric Blake <ebb9@byu.net>
2393 Stage 3a: cache length, rather than computing it, in libm4.
2394 Cache the length of a token in the input engine and symbol table,
2395 to avoid repeating lots of strlen calls. Additionally, by using
2396 obstack length rather than strlen, the input engine can now
2397 support embedded NUL.
2398 Memory impact: slight penalty, due to larger struct.
2399 Speed impact: slight improvement, due to fewer function calls.
2400 * m4/m4module.h (struct m4_macro_args): Cache length.
2401 (m4_get_symbol_len, m4_get_symbol_value_len): New accessors.

2423 Adjust implementation.
2425 2007-11-27 Eric Blake <ebb9@byu.net>
2427 Stage 2: use accessors, not direct reference, into argv.
2428 Outside of macro.c, use accessor methods rather than direct access
2429 into the argv struct.
2430 Memory impact: none.
2431 Speed impact: slight penalty, due to increased function calls.
2432 * m4/m4private.h (m4_arg_argc): New fast accessor.
2433 * m4/m4module.h (m4_arg_argc, m4_arg_symbol, m4_is_arg_text)

2435 prototypes.
2436 (m4_builtin_func, M4BUILTIN, M4BUILTIN_HANDLER, m4_dump_args)
2437 (m4_macro_call): Make argc unsigned.
2438 (M4ARG): Use new accessors.
2439 * modules/m4.c (define, pushdef): Likewise.
2440 (undefine, popdef, ifelse, m4_dump_symbols, defn, undivert)

2451 (expand_macro, trace_pre, trace_post, m4_macro_call): Update argc
2452 usage.
2454 2007-11-24 Eric Blake <ebb9@byu.net>
2456 Stage 1: convert m4_symbol_value** into new object.
2457 Pass a variable-size wrapper structure instead of an array to
2458 builtins, so that subsequent optimizations in the structure need
2459 not impact every builtin client.
2460 Memory impact: slight penalty, since struct is larger than array.
2461 Speed impact: slight penalty, due to increased bookkeeping.
2462 * ltdl/m4/gnulib-cache.m4: Import flexmember module.
2463 * m4/m4module.h (m4_macro_args): New type, will be opaque to
2464 modules later.
2465 (m4_builtin_func, M4BUILTIN, M4BUILTIN_HANDLER, m4_dump_args)

2528 2007-11-14 Eric Blake <ebb9@byu.net>
2530 Handle some defn corner cases differently.
2531 * doc/m4.texinfo (Defn): Update documentation; although this still
2532 doesn't match the branch, since it may be changed before 2.0.
2533 * m4/macro.c (expand_argument): Consistently ignore builtins in
2534 concatenation contexts.
2535 * m4/m4private.h (m4__symbol_type): Fix C89 compliance bug.
2537 2007-11-13 Eric Blake <ebb9@byu.net>
2539 Note: Patches titled Stage 0 through N form a series of patches
2540 which decreases the algorithmic complexity of tail recursion in
2541 macro expansions from O(n^2) to O(n) in both time and memory, then
2542 performs cleanups, such as handling of embedded NUL, made easier
2543 by the code refactoring.
2545 Stage 0: Fix memory leak in tail recursion.
2546 Free expansion text in the input engine as soon as it is parsed,
2547 rather than when the recursive expansion completes.
2548 Memory impact: noticeable improvement, due to reduction from
2549 O(n^2) to O(n) on recursion.

3230 Get rid of the last 'differs in signedness' compiler warnings:
3232 * m4/macro.c (process_macro): m4_get_symbol_value_text() returns

3241 M4 was designed to have a small number of header files defining
3242 the interfaces to several source files each. Keeping this in
3243 mind allows us to tidy things up considerably. Having done this,
3244 it becomes clear that some of the installed headers reference

3248 here...

5347 atlocal takes care of it instead.

5349 path to testsuite here, rather than relative path to testsuite
5350 elsewhere.

5407 type-punning warnings caused trying to mix these types.
5408 * modules/mpeval.c (numb_ior, numb_eor, numb_and, numb_lshift),
5409 (numb_rshift, numb_divide, numb_modulo): Remove const qualifier.

5411 (mult_term, exp_term): Remove type-punning casts.
5412 (numb_pow): Remove const qualifier.
5413 * src/freeze.c (reload_frozen_state): Fix typo in messages.
5414 Fix variables that can be used uninitialized, which fixes
5415 security hole where malicious frozen file can execute arbitrary
5416 code.
5418 2006-06-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5420 * Makefile.am (modules_mpeval_la_LIBADD): Readd $(LIBADD_GMP).
5422 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5423 and Eric Blake <ebb9@byu.net>
5425 Allow `make dist' to work again.
5426 * Makefile.am (EXTRA_DIST): doc/helptoman.pl is gone.
5427 (MAINTAINERCLEANFILES): Avoid redundant mention of dist_man_MANS.
5428 (cvs-dist): Fix typo.
5429 * NEWS: Match current version number.
5431 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5433 * Makefile.am (AM_CPPFLAGS): Add $(LTDLINCL), so the right
5434 ltdl.h is used.
5436 * bootstrap: Do not run libtoolize manually, this is done
5437 correctly by autoreconf. Invoke autoreconf with --no-recursive
5438 to avoid unnecessary rerunning of autotools for libltdl.
5440 2006-06-13 Eric Blake <ebb9@byu.net>
5442 * THANKS: Update.
5444 2006-06-12 Eric Blake <ebb9@byu.net>
5446 * m4/output.c [HAVE_MKTEMP]: Gnulib provides mkstemp, so don't
5447 bother with mktemp.
5448 * src/m4.h: Don't declare mktemp.
5449 * m4/input.c (m4__next_token): Avoid bzero.
5450 * configure.ac (AC_CHECK_FUNCS): Remove obsolete checks.
5451 * Makefile.am (doc/m4.1): Depend on installed help2man, rather
5452 than distributing outdated helptoman.pl.
5453 * doc/helptoman.pl: Delete.
5455 2006-06-10 Eric Blake <ebb9@byu.net>
5457 * README (Patches): Document the current dependence on CVS
5458 builds of autotools.
5459 * ltdl/m4/gnulib-cache.m4: Update, and use --macro-prefix=M4.

5463 (AC_ARG_WITH): Use AS_HELP_STRING.
5464 (AM_INIT_AUTOMAKE): Enable gnits mode.
5465 (AC_ISC_POSIX, AM_PROG_CC_STDC, AC_PROG_INSTALL, AC_PROG_MAKE_SET),
5466 (AC_PROG_AWK, AM_C_PROTOTYPES, AC_C_CONST, AC_HEADER_STDC),
5467 (AC_CHECK_HEADERS, AC_FUNC_ALLOCA, AC_FUNC_VPRINTF): Remove checks
5468 done by gnulib or automake, or which autoconf has declared
5469 obsolete.
5470 * m4/m4private.h (Includes): Assume C89 or better, and use errno
5471 unconditionally.

5479 about cygwin. Document bootstrapping dependency.
5480 * AUTHORS: Update from branch-1_4.

5482 * BACKLOG: Delete. This file is too old and unmaintained to be
5483 worthwhile.
5484 * ChangeLog: Change encoding to UTF-8.
5486 Avoid compiler warnings.
5487 * m4/macro.c (trace_format): Don't mark this as a printf format,
5488 since we don't accept the same set of modifiers as printf. It
5489 would be nice if gcc let us specify a custom format archetype.
5490 * src/main.c (main): Cast away const.
5492 2006-06-10 Andreas Schwab <schwab@suse.de> (tiny change)
5493 Eric Blake <ebb9@byu.net>
5495 * modules/time.c (ctime): Pass correctly typed variable to
5496 m4_numeric_arg.
5497 (gmtime): Likewise.
5498 (localtime): Likewise.
5499 (strftime): Likewise.
5500 * m4/utility.c (m4_numeric_arg): For now, document arbitrary
5501 limit inherent in this interface.
5503 2006-05-08 Bruno Haible <bruno@clisp.org> (tiny change)
5505 * modules/m4.c (WEXITSTATUS): Provide fallback definition.
5506 (sysval): Use WEXITSTATUS.
5507 * modules/gnu.c (esyscmd): Set sysval to 0xffff, to accomodate both
5508 big-endian and little-endian wait status definitions.
5510 2006-05-06 Eric Blake <ebb9@byu.net>
5512 * po/Makevars (MSGID_BUGS_ADDRESS): Add.
5513 * po/POTFILES.in (src/getopt.c, src/version-etc.c): These files live
5514 in src, not gnu.
5516 2006-05-06 Eric Blake <ebb9@byu.net>
5518 * configure.ac (LT_CONFIG_LTDL_DIR): Inform libtool which
5519 subdirectory to use.
5520 (support for -pipe): Move after LT_INIT, since it relies on
5521 libtool internals.
5523 2006-05-05 Eric Blake <ebb9@byu.net>
5525 * Makefile.am (doc/m4.1): Use $@, not $(srcdir)/doc/$@.
5527 * THANKS: Update.
5529 2006-05-05 Bruno Haible <bruno@clisp.org>
5530 and Eric Blake <ebb9@byu.net>
5532 * configure.ac (gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES): Move to...
5533 * ltdl/m4/gnulib-cache.m4: ...this new file, per new gnulib-tool
5534 usage pattern.
5535 * bootstrap: Update usage of gnulib-tool.
5537 2006-05-04 Eric Blake <ebb9@byu.net>
5539 * Makefile.am (doc/m4.1): Use EXEEXT on built binary.
5540 Cleanup whitespace.
5542 2005-12-05 Gary V. Vaughan <gary@gnu.org>
5544 * bootstrap (func_update_po): Synch with CVS GNU tar. wget 1.9.x
5545 and 1.10.x support --cache=off, so $WGETFLAGS are not necessary.
5546 Reported by Eric Blake <ebb9@byu.net>
5548 2005-12-04 Gary V. Vaughan <gary@gnu.org>
5550 * bootstrap (func_update_po): Test and set $WGETFLAGS to disable
5551 http caching as -C is no longer supported by wget 1.10.x.
5552 Reported by Eric Blake <ebb9@byu.net>
5554 2005-10-20 Gary V. Vaughan <gary@gnu.org>
5556 * m4/module.c (caller_id): To match libtool-2.0 interface, changed
5557 to ...
5558 (iface_id): ...an lt_dlinterface_id type.
5559 (m4__module_find): New abstraction for lt_dlhandle_fetch. Use
5560 throughout, instead of calling obsolete lt_dlhandle_find directly.
5561 (m4__module_next): Use multiloader-safe lt_dlhandle_iterate. Use
5562 throughout, instead of calling obsolete lt_dlhandle_next.
5563 * m4/m4private.h (m4__module_find): Declare it.
5564 * m4/builtin.c (m4_builtin_find_by_name, m4_builtin_find_by_func):
5565 Use m4__module_next instead of obsolete lt_dlhandle_next.
5567 2005-10-20 Gary V. Vaughan <gary@gnu.org>
5569 * bootstrap (func_update_po): Update pofiles directly from the
5570 translation project.
5571 * po/LINGUAS, po/cs.po, po/de.po, po/el.po, po/fr.po, po/it.po,
5572 po/ja.po, po/nl.po, po/pl.po, po/ru.po, po/sv.po: No need to store
5573 these files under source control anymore.
5574 Suggested by Eric Blake <ebb9@byu.net>
5576 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
5578 * ltdl/m4/m4-gnulib.m4: Update FSF contact address. Somehow this
5579 file escaped the address updates on 2005-05-01.
5581 2005-07-07 Gary V. Vaughan <gary@gnu.org>
5583 * bootstrap: Allow user overriding of gnulib-tool location, and
5584 correctly determine module source directories whether gnulib-tool
5585 is given as a relative or absolute path, or is found by searching
5586 PATH.
5587 Reported by Eric Blake <ebb9@byu.net>
5589 2005-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5591 * ltdl/m4/debug.m4 (m4_CHECK_DEBUGGING): Make sure that both $rm
5592 and $RM are defined for various versions of
5593 AC_LIBTOOL_COMPILER_OPTION.
5595 * bootstrap (AUTORECONF): New variable to allow user overriding of
5596 autoreconf path.
5598 2005-07-07 Gary V. Vaughan <gary@gnu.org>
5600 * doc/m4.texinfo (History): Add better notes on the ancestory of
5601 GNU m4, and other historical interest.
5603 2005-05-08 Gary V. Vaughan <gary@gnu.org>
5605 * m4/symtab.c (m4_symbol_rename): New function that performs a low
5606 level symbol rename.
5607 * m4/m4module.h (m4_symbol_rename): Declare it as part of the API.
5608 * modules/gnu.c (regsub): Factored out of m4_epatsubst_do...
5609 (m4_patsubst_do, m4_renamesyms_do): ...wrappers that use
5610 regsub...
5611 (erenamesyms, renamesyms): ...builtins that use these to implement
5612 macro renaming by regular expression.
5613 * doc/m4.texinfo (Erenamesyms and Renamesyms): Document them.
5614 * tests/generate.awk: Allow some forbidden `m4_' prefixed symbols
5615 to stop the new generated tests from choking.
5617 2005-05-07 Gary V. Vaughan <gary@gnu.org>
5619 Since most of the build is handled from a single Makefile.am now,
5620 we can teach make about the dependencies between the m4 binary and
5621 the preopened modules it is built against:
5623 * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
5624 preopened modules.
5625 * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
5626 of the preopened modules have changed.
5628 2005-05-07 Gary V. Vaughan <gary@gnu.org>
5630 * configure.ac (gl_MODULES): Add mkstemp for machines that don't
5631 have a native implementation.
5633 2005-05-06 Gary V. Vaughan <gary@gnu.org>
5635 * src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are
5636 handled already by gnu/exit.h.
5638 * configure.ac (gl_MODULES): Add assert to support a
5639 --disable-assert configure time option for NDEBUG setting.
5641 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.
5642 * bootstrap (src_modules): Add version-etc-fsf.
5643 * src/main.c (version_etc_copyright): Removed.
5645 * ltdl/m4/m4-getopt.m4 (m4_GETOPT): Synch with gnulib/getopt.m4.
5647 2005-05-04 Gary V. Vaughan <gary@gnu.org>
5649 * src/m4.h (__CYGWIN__, WIN32): Canonicalise Windows and Cygwin
5650 recognition macros.
5651 * src/freeze.c (produce_frozen_state): Use \n line-endings even
5652 on Windows, so that the frozen file reader will work.
5653 Reported by Josef T. Burger <bolo@bolo.com>
5655 2005-05-04 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
5657 Forward port of a patch that allowed m4-1.4.2 to compile on
5658 QNX 6.3:
5660 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
5661 sys/signal.h.
5662 * src/m4.h: And include them as appropriate.
5663 * src/main.c, src/stackovf.h: Don't include signal.h literally;
5664 m4.h will include the correct file.
5666 2005-05-04 Gary V. Vaughan <gary@gnu.org>
5668 * m4/m4private.h: Make errno visible for the sources patched
5669 below.
5671 2005-05-04 Paul Eggert <eggert@twinsun.com>
5673 * src/main.c (print_program_name_CB): Preserve errno, since
5674 M4ERROR relies on this.
5675 * modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
5676 * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
5677 * m4/path.c (m4_path_search): Don't let "free" trash errno when
5678 returning NULL.
5680 * m4/output.c (m4_insert_file): Don't assume errno has a valid
5681 value simply because fread returns zero. This fixes a
5682 portability bug reported by Marion Hakanson in
5683 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
5685 2005-05-04 Santiago Vila <sanvila@debian.org>
5687 * tests/stackovf.test: Use tempfile if available.
5689 2005-05-04 Robert Bihlmeyer <robbe@orcus.priv.at> (tiny change)
5691 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=92629
5692 * m4/output.c (m4_insert_file): Do not mix buffered and
5693 unbuffered I/O, as this breaks on the Hurd.
5695 2005-05-04 Gary V. Vaughan <gary@gnu.org>
5697 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
5698 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
5699 and libtoolize does a better job of ltdl importing now too, so
5700 take advantage of that while updating the tree:
5702 * acm4, config: Moved from here...
5703 * ltdl/m4, ltdl/config: ...to here.
5704 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
5705 src/Makefile.am, tests/Makefile.am: Removed...
5706 * Makefile.am: ...and migrated to here, with adjustments to
5707 compensate for relative path differences.
5708 * commit: Adjust relative paths.
5709 * configure.ac: Adjust relative paths.
5710 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
5711 patch.
5712 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
5713 the meanwhile, CVS HEAD libtool is needed.
5714 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
5715 stricly new enough, we also need a patch.
5716 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
5717 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
5718 (gl_MODULES): Don't list getopt and version-etc, as they don't
5719 belong in libm4.
5720 * bootstrap: After running gnulib-tool to import the listed
5721 modules, fetch getopt and version-etc into src manually.
5722 (ltdldir): Change to ltdl.
5723 * src/main.c: Adjust for changes in version-etc API.
5724 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
5725 but works when the getopt module isn't to be included in the lib.
5726 * README: Add note about patching autoconf and automake to
5727 bootstrap CVS m4.

5731 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=84416
5732 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
5733 empty file rather than to a nonexistent file. This closes a
5734 common security hole.
5735 * modules/m4.c (m4_maketemp): Implement the above, by using
5736 mkstemp rather than mktemp.
5738 2005-05-01 Gary V. Vaughan <gary@gnu.org>
5740 The FSF are moving offices today. Changed their contact address

5771 to the gnu subdirectory.
5772 * acm4/m4-error.m4 (INCLUDE_ERROR_H): Likewise.
5773 * acm4/m4-obstack.m4 (INCLUDE_OBSTACK_H): Likewise.
5774 * acm4/m4-regex.m4 (INCLUDE_REGEX_H): Likewise.

5777 2004-10-14 Noah Misch <noah@cs.caltech.edu>,
5778 Gary V. Vaughan <gary@gnu.org>
5780 * m4/m4.c (m4_context_field_table, m4_context_opt_bit_table):
5781 Protect definitions from macro expansion under -DNDEBUG by
5782 parenthesising the expanded function names.
5783 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
5784 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
5785 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
5786 (m4_is_syntax_macro_escaped): Similarly protect function
5787 definitions from macro expansion under -DNDEBUG by #undefing the
5788 matching macro names before each definition. Also, move all the
5789 function definitions to the end of the file so that any
5790 invocations in the rest of the file pick up the fast macro
5791 versions.
5792 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)
5793 (m4_set_debug_file, m4_set_trace_messages)
5794 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
5795 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
5796 (m4_set_max_debug_arg_length_opt): New fast macro versions of the
5797 option setter functions.
5799 2004-09-23 Gary V. Vaughan <gary@gnu.org>
5801 * po/POTFILES.in: Reflect move of gnulib files from gnulib/m4
5802 to gnu.
5804 2004-09-23 Gary V. Vaughan <gary@gnu.org>
5806 * src/main.c: Include gnulib files from the correct directory.
5808 * gnulib/*: Don't store any of the gnulib files in arch, as they
5809 generate spurious changes.
5810 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
5811 gnulib macros now share our macro directory.
5812 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
5813 * bootstrap: Call gnulib-tool to import from the gnulib tree.
5814 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
5815 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
5816 the gettext macros from autopoint that overwrite the gnulib-tool
5817 imported versions. Import sources and Makefile.am into the `gnu'
5818 directory. Changed all callers.
5819 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
5820 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
5821 for imported modules.
5822 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
5823 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
5824 hardcoding the gnulib macros they wrap.
5826 2004-07-15 Gary V. Vaughan <gary@gnu.org>
5828 Latest CVS libtool can preload modules in libraries, including
5829 its own module loaders! Tweak m4 so that it doesn't try to treat
5830 libltdl's module loaders as m4 modules when freezing and on exit:
5832 * gnulib/acm4/*.m4: Don't store these files in arch since they
5833 generate spurious changes.
5834 * bootstrap: Simplify initial libtoolize call, since CVS
5835 libtoolize is smarter these days.
5836 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
5837 build.
5838 * m4/module.h (m4__module_exit): Missing declaration.
5839 * m4/m4private.h (m4__module_next): New function declaration.
5840 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
5841 encapsulation. Changed all callers.
5842 (m4__module_interface): New function to verify m4 loadable module
5843 interfaces.
5844 (m4__module_init): Register the interface validator.
5845 (m4__module_exit): Only close my own modules.
5846 * modules/m4.c (unistd.h): Provide missing declaration.
5847 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
5848 (m4_expand_ranges): More missing declarations.
5849 * modules/modtest.c (export_test): Ditto.
5850 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
5851 * src/main.c (main): Bump copyright year.
5852 * tests/modules.at: Fix sed syntax error.
5855 2004-06-17 Gary V. Vaughan <gary@gnu.org>
5857 Tweaking to enable compilation with latest CVS libtool and
5858 libltdl. We can't just dump the library files directly into the
5859 m4 directory anymore now that libltdl is built from pieces itself:
5861 * bootstrap: Rewritten to use latest libtoolize sanely, and to
5862 set up libltdl subdirectory.
5863 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
5864 gnulib subdirectory's config.
5865 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
5866 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
5867 macros from gnulib.
5868 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
5869 configure.ac, so use AC_WITH_LTDL instead.
5870 * Makefile.am (SUBDIRS): Add libltdl.
5871 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
5872 gl_INCLUDED_REGEX.
5873 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
5874 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
5875 (libm4_la_LIBADD): Add LIBLTDL.
5876 * m4/ltdl.c, m4/ltdl.h: Removed.
5877 * m4/m4module.h: Include canonical ltdl.h.
5878 * po/*.po: Updated.
5880 2004-06-14 Gary V. Vaughan <gary@gnu.org>
5882 * gnulib/import: Now updates makefile fragments, and configure.ac.
5883 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
5884 * gnulib/m4/Makefile.am: include it.
5885 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
5886 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
5887 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
5888 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,

5896 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
5897 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
5898 import.
5899 * gnulib/m4/getopt_int.h: New source file from latest gnulib
5900 import.
5901 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
5902 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,

5904 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
5905 Updated source files from latest gnulib.
5907 2004-02-29 Gary V. Vaughan <gary@gnu.org>
5909 * config/mailnotify: New file for mailing commit notifications,
5910 imported from cvs-utils.
5911 * commit: Updated from cvs-utils and tweaked for m4.
5913 2003-12-01 Gary V. Vaughan <gary@gnu.org>
5915 * config/mkstamp: Updated from CVS libtool.
5916 * configure.ac: Generate a gnu coding standards compliant version
5917 number, and use it for the banner.
5918 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
5919 mhen the TIMESTAMP changes in ChangeLog, but the file modification
5920 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
5921 contain the previous version number.
5922 * src/main.c: Make --version output conform to the GNU standard.
5924 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
5925 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
5926 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
5927 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
5928 time_la_SOURCES): ...so that these are defaulted correctly, and
5929 can be removed from this file.
5930 (AM_LDFLAGS): Add -module...
5931 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
5932 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
5933 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
5934 the individual settings can be removed.
5935 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
5936 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
5937 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
5938 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
5939 time_la_LIBADD): ...so that these are picked up as a deplib of
5940 libm4 and don't need to be set explicitly.
5942 2003-11-18 Gary V. Vaughan <gary@gnu.org>
5944 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
5945 from the standard build. It is too fragile.
5947 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
5948 CVS libtool after merging m4 changes across to libtool.
5950 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
5951 * m4/path.c (search_path_add): Ditto.
5953 2003-11-13 Gary V. Vaughan <gary@gnu.org>
5955 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
5956 libtool tags we don't use in configure. This reduces the size
5957 of the script from over 1Mb to under 700Kb.
5959 2003-11-13 Gary V. Vaughan <gary@gnu.org>
5961 The import script was not written properly, and the last gnulib
5962 import was incomplete. Fixed that problem, and reimport our
5963 gnulib dependencies, which picks up the address calculation
5964 overflow checks described by Paul below. Also tweak the clients
5965 of the gnulib xalloc module not to use deprecated macros:
5967 * gnulib/import: Recurse through module dependencies rather than
5968 naively descending only one level.
5969 * configure.ac: Add calls to gnulib's strnlen and extension module
5970 macros.
5971 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
5972 extension modules.
5973 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
5974 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
5975 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
5976 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
5977 gnulib.
5978 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
5979 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
5980 place of `xcalloc (1, S)'.
5981 * m4/m4.c (m4_create): Likewise.
5982 * m4/m4private.h (m4_symbol_value_create): Likewise.
5983 * m4/symtab.c (symtab_fetch): Likewise.
5984 * m4/syntax.c (m4_syntax_create): Likewise.
5985 * src/freeze.c (reload_frozen_state): Likewise.
5986 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
5987 macro.
5988 * m4/symtab.c (m4_symtab_create): Likewise.
5990 2003-11-13 Gary V. Vaughan <gary@gnu.org>
5992 * tests/module.at: Comment typo.
5994 2003-10-10 Gary V. Vaughan <gary@gnu.org>
5996 * tests/modules.at (modules: importing): Apply some lateral
5997 thinking, and use AT_CHECK to compare the output of a sed pass
5998 over stderr against the canonical strerror string.
6000 * tests/modules.at (modules: importing): Edit the generated stderr
6001 output to canonicalize strerror output, before a comparison.
6003 2003-10-10 Gary V. Vaughan <gary@gnu.org>
6005 Tru64UNIX perl is sloppy with namespace pollution. This patch is
6006 careful not to trip over the mess:
6008 * modules/perl.c: Some builds of perl install headers that contain
6009 `#define try __builtin_try'. Be sure to undefine that macro
6010 before `m4/hash.h' gets included, which uses the `try' symbol.
6011 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
6012 `false' before including `stdbool.h'.
6013 (DELETE): This symbol is not in m4's namespace, and is in any
6014 case only used internally...
6015 * m4/m4private.h (DELETE): ...so move it to here.
6016 Reported by Martin MOKREJS <mmokrejs@natur.cuni.cz>
6018 2003-10-08 Paul Eggert <eggert@twinsun.com>
6020 Don't use XMALLOC and XCALLOC. Once we install the
6021 corresponding patch into gnulib, this will fix some
6022 address-calculation overflow bugs on hosts where calloc (A, B)
6023 returns garbage when A*B overflows.
6025 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
6026 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
6027 xmalloc, XCALLOC with xcalloc.
6028 * m4/m4.c (m4_create): Likewise.
6029 * m4/m4private.h (m4_symbol_value_create): Likewise.
6030 * m4/output.c (m4_output_init): Likewise.
6031 * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise.
6032 * m4/syntax.c (remove_syntax_attribute): Likewise.
6033 * src/freeze.c (reload_frozen_state): Likewise.
6034 * src/main.c (main): Likewise.
6036 2003-10-07 Gary V. Vaughan <gary@gnu.org>
6038 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
6039 gnulib/acm4 directories for aclocal m4 macros.
6040 * gnulib/Makefile.am (EXTRA_DIST): Removed.
6041 (MAINTAINERCLEANFILES): Add Makefile.in.
6042 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
6043 modules we use.
6044 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
6045 * gnulib/import: New file. Temporary script for updating gnulib
6046 imported files, until gnulib-tool is working.
6047 * gnulib/config/codeset.m4, gnulib/config/error.m4,
6048 gnulib/config/exitfail.m4, gnulib/config/extensions.m4,

6084 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
6085 gnulib/acm4/xstrndup.m4: Reimported from CVS gnulib with
6086 gnulib/import script.
6087 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/error.c,

6091 gnulib/m4/version-etc.c, gnulib/m4/version-etc.h,
6092 gnulib/m4/xalloc.h, gnulib/m4/xmalloc.c: Updated from CVS
6093 gnulib with gnulib/import script.
6094 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
6095 guards ready for gnulib-tool to autoupdate on import.
6096 * config/debug.m4, config/gmp.m4, config/m4-error.m4,
6097 config/m4-gettext.m4, config/m4-obstack.m4, config/m4-regex.m4,
6098 config/stackovf.m4: Moved from here...
6099 * acm4/debug.m4, acm4/gmp.m4, acm4/m4-error.m4,
6100 acm4/m4-gettext.m4, acm4/m4-obstack.m4, acm4/m4-regex.m4,
6101 acm4/stackovf.m4: ...to here, to separate aclocal macros from
6102 configure time helper scripts.
6103 * config/error.m4: Removed; superceded by gnulib/acm4/error.m4.
6104 * m4/hash.c, m4/m4.c, m4/macro.c, m4/module.c, m4/output.c,
6105 m4/path.c, m4/symtab.c, m4/syntax, m4/system_.h, modules/m4.c,
6106 src/main.c, src/stackovf.c: s/xfree/free/g to comply with new
6107 gnulib xalloc.h.
6108 * src/main.c (version_etc_copyright): Only output the current
6109 year.
6110 (version_etc): Call with new variadic API.
6112 2003-09-16 Gary V. Vaughan <gary@gnu.org>
6114 * gnulib/m4/version-etc.c, gnulib/m4/version-etc.h: Import
6115 version-etc module from CVS gnulib.
6116 * po/POTFILES.in: Add gnulib/m4/version-etc.c.
6117 * src/Makefile.am: Build it.
6118 * src/main.c: Use it.
6120 * gnulib/m4/exit.h: Import exit module from CVS gnulib.
6121 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
6122 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
6123 exit.h instead.
6125 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
6126 Gary V. Vaughan <gary@gnu.org>
6128 * bootstrap: Separate options.
6129 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
6130 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
6131 not set.
6132 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
6133 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
6134 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
6135 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
6136 $(LTLIBINTL) for gettext support on cygwin.
6137 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
6138 have $(LTLIBINTL) from the preloaded module la files.
6139 * README: Remove the warning about using --disable-nls on Windows
6140 machines.
6142 2003-09-15 Gary V. Vaughan <gary@gnu.org>
6144 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
6145 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
6146 is required.
6148 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6150 * doc/STYLE: Document the gnulib header naming conventions, and
6151 #include policy.
6152 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
6153 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,
6154 gnulib/m4/gettext.h, gnulib/m4/obstack.h, gnulib/m4/regex.h
6155 respectively.
6156 * gnulib/m4/Makefile.am: Remove the rules to build these headers.
6158 * gnulib/m4/strtol.c, gnulib/config/strtol.m4: Import strtol
6159 module from CVS gnulib.
6160 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
6161 (gl_FUNC_STRTOL): In favour of the module macro.
6163 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6165 Replace the getopt code with CVS gnulib getopt. The source files
6166 detect whether they are in a glibc environment and preprocess away
6167 all of the code if there is a system getopt, so we can compile
6168 them into the m4 executable unconditionally:
6170 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
6171 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
6172 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
6173 macros.
6174 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
6175 version.
6176 * src/Makefile.am: Adjust.
6177 * src/main.c: Always include our shipped getopt.h.
6178 * po/POTFILES.in: Use new location of getopt.c.
6180 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6182 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
6183 * config/Makefile.am: Removed. Automake 1.8 distributes the files
6184 in this directory automatically.
6185 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
6187 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
6188 isn't set yet.
6189 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
6190 inline.
6191 * modules/Makefile.am (pkglibexecdir): Set it here.
6192 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
6194 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
6195 Import regex module from CVS gnulib.
6196 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
6197 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
6198 do extra substitutions for Makefile.
6199 * configure.ac: Use it.
6200 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
6201 from regex_.h if necessary.
6202 * m4/system_.h: Include the correct version of regex.h.
6203 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
6204 version.
6205 * po/POTFILES.in: Use new location of regex.c.
6207 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
6208 realloc.c: automake distributes these files already.
6210 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6212 Replace the xstrzdup code by importing the xstrndup module from
6213 CVS gnulib, along with its dependencies: strndup and strnlen:
6215 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
6216 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
6217 gnulib.
6218 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
6219 gnulib/config/strndup.m4: Ditto wrt strndup.
6220 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
6221 strnlen.
6222 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
6223 However, contrary to gnulib, we install xstrndup.h.
6224 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
6225 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
6226 is an artifact of the old m4 portability layer.
6227 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
6228 * m4/system_.h: Include xstrndup.h.
6229 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
6231 2003-09-11 Gary V. Vaughan <gary@gnu.org>
6233 Reimport the latest xalloc module from CVS gnulib, and adjust the
6234 m4 sources to take advantage of xalloc xfree. Also create a new
6235 macro DELETE with the same semantics as the old m4 XFREE macro,
6236 and carefully tweak callers:
6238 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
6239 gnulib.
6240 * m4/utility.c (xfree): Removed. This function is now supplied by
6241 gnulib xalloc.
6242 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
6243 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
6244 * m4/symtab.c (m4_symtab_create): Ditto.
6245 * m4/system_.h: Removed XFREE redefine.
6246 (DELETE): New macro with same functionality as the original m4
6247 XFREE macro, but based on xalloc.h now. Changed all callers.
6248 * src/main.c (main): Use XMALLOC macro.
6249 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
6250 instead of XFREE.
6251 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
6253 2003-09-10 Gary V. Vaughan <gary@gnu.org>
6255 Import the xalloc module from CVS gnulib, along with its
6256 dependencies: exitfail, malloc and realloc. We had different
6257 semantics for our XFREE and a function xfree() not supplied by
6258 gnulib, so also a bit of work to keep everything running
6259 smoothly:
6261 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
6262 (gl_XALLOC): Use gnulib equivalents.
6263 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
6264 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
6265 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
6266 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
6267 realloc.
6268 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
6269 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
6270 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
6271 imported modules.
6272 (pkgincdir): Removed. Use pkgincludedir instead.
6273 * m4/m4private.h (XFREE): xfree already checks for NULL.
6274 * m4/system_.h: Use xalloc module, and remove macros already
6275 supplied by xalloc.h.
6276 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
6277 moved the old definition from m4/xmalloc.c to here for now.
6279 2003-09-09 Gary V. Vaughan <gary@gnu.org>
6281 Import the error and progname modules from CVS gnulib. Our old
6282 error.c subsumed the functionality of both, so a little adjustment
6283 was required to accomodate the split in sources. Also added more
6284 wrapper macros to choose between a system installed error.h or our
6285 shipped gnulib error module:
6287 * m4/error.c, m4/error.h: Removed.
6288 * m4/Makefile.am: Adjust.
6289 (pkgincdir): Removed. Use pkgincludedir instead.
6290 * m4/module.h, src/main.c: Don't include `m4/error.h'.
6291 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
6292 error.h.
6293 * gnulib/m4/progname.c: Imported from CVS gnulib.
6294 * gnulib/m4/progname.h: Ditto.
6295 * src/main.c: Adjust to use progname module.
6296 * gnulib/m4/error.c: Imported from CVS gnulib.
6297 * gnulib/m4/error_.h: Ditto.
6298 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
6299 if appropriate, and link a local error.h if the system version is
6300 missing.
6301 (libgnu_la_SOURCES) Add progname module sources.
6302 * gnulib/config/error.m4: Imported from CVS gnulib.
6303 * gnulib/config/strerror_r.m4: Ditto.
6304 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
6305 to have ERROR_H for Makefile substitutions and tell system.h
6306 whether the system error.h should be used, or a locally installed
6307 version.
6308 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
6310 2003-09-09 Gary V. Vaughan <gary@gnu.org>
6312 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
6313 s/gettext_.h/gettext.h/.
6315 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
6316 automake have been fixed.
6318 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
6319 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
6320 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
6321 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
6323 2003-09-09 Gary V. Vaughan <gary@gnu.org>
6325 The gnulib obstack module requires the gnulib gettext module for
6326 systems that do not have GNU gettext installed. Because we use
6327 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
6328 that directory incase it clashes with the system gettext.h. This
6329 delta uses gettext_.h and extra rules in the Makefile to make a
6330 link to gettext.h when needed:
6332 * Makefile.am (auxdir): Removed. No longer used.
6333 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
6334 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
6335 moved.
6336 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
6337 Makefile based build.
6338 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
6339 of the macros are kept.
6340 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
6341 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
6342 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
6343 distributes these automatically.
6344 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
6345 warning from automake-1.7a.
6346 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
6347 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
6348 all callers.
6349 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
6350 wrt. m4_FUNC_OBSTACK.
6351 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
6352 wrt. m4_sys_STACKOVF.
6353 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
6354 wrt. _m4_LIB_GMP, m4_LIB_GMP.
6355 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
6356 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
6357 respectively.
6358 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
6359 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
6360 gettext.h link on deficient systems.
6361 (pkginc_HEADERS): Mention $(GETTEXT_H).
6362 (EXTRA_HEADERS): Mention gettext.h.
6363 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
6364 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
6365 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
6366 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
6367 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
6368 gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
6369 gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
6370 gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
6371 gnulib/config/po.m4, gnulib/config/progtest.m4,
6372 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
6373 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
6375 2003-09-05 Gary V. Vaughan <gary@gnu.org>
6377 We can't mirror the gnulib directory structure here, since we need
6378 to be able to eg. `#include <m4/obstack.h>' from our source files,
6379 which is much easier if the local obstack.h is created in a
6380 directory named m4. Rather than trying to symlink everything into
6381 the m4 directory, now we build a libtool convenience library from
6382 the sources we get from gnulib and link that with libm4.la:
6384 * gnulib/config/extensions.m4: Imported from CVS gnulib.
6385 * gnulib/config/unlocked-io.m4: Ditto.
6386 * gnulib/m4/unlocked-io.h: Ditto.
6387 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
6388 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
6389 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
6390 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
6391 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
6392 * m4/Makefile.am: Adjust.
6393 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
6394 macros we redistribute.
6395 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
6396 library among others.
6397 (GNULIB_SRCS, GNULIB_MACROS): Removed.
6398 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
6399 * config/m4-obstack.m4: Adjust.
6400 * po/POTFILES.in: Adjust.
6401 * configure.ac: Reformatting. Call newly imported gnulib macros.
6402 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
6403 bogus calls of `#include "m4.h"'.
6404 * Makefile.am: INCLUDES has been deprecated in favour of
6405 AM_CPPFLAGS.
6406 * m4/Makefile.am: Ditto.
6407 * modules/Makefile.am: Ditto.
6408 * src/Makefile.am: Ditto.
6410 2003-09-05 Gary V. Vaughan <gary@gnu.org>
6412 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
6414 2003-09-04 Gary V. Vaughan <gary@gnu.org>
6416 Migrate the obstack support into the gnulib directories for easy
6417 synchronisation with upstream files in gnulib:
6419 * config/gnu-obstack.m4: Moved from here...
6420 * config/m4-obstack.m4: ...to here.
6421 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
6422 * m4/obstack.c, m4/obstack_.h: Moved from here...
6423 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
6424 * po/POTFILES.in: Adjust.
6425 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
6426 * m4/Makefile.am: Add a whole new section to link the obstack
6427 sources from the gnulib tree if necessary.
6428 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
6429 from gnulib.
6430 * config/m4-obstack.m4: Rewrite as a wrapper for
6431 gnulib/m4/obstack.m4.
6433 2003-09-04 Gary V. Vaughan <gary@gnu.org>
6435 GNU M4 currently builds with a number of files adapted from
6436 upstream sources. Recently the gnulib project on savannah.gnu.org
6437 has pulled together a great many of these externally maintained
6438 files. This delta is the beginnings of isolating those files
6439 maintained in gnulib to make it easy to synchronise M4 with the
6440 upstream files prior to releases.
6442 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
6443 directory.
6444 (SUBDIRS): Added new gnulib subdirectory.
6445 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
6446 * config/stdbool.m4: Moved from here...
6447 * gnulib/m4/stdbool.m4: ...to here.
6448 * m4/stdbool_.h: Moved from here...
6449 * gnulib/lib/stdbool_.h: ...to here.
6450 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
6451 distributed.
6452 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
6453 code to work with new stdbool_.h location.
6454 (gnulib_srcdir): New.
6456 2003-09-04 Gary V. Vaughan <gary@gnu.org>
6458 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
6459 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
6460 builds to work.
6461 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
6462 (EXTRA_DIST): Use it.
6464 * bootstrap: CVS autoreconf leaves file droppings. Remove
6465 aclocal.m4t incase autoreconf doesn't.
6467 2003-08-29 Gary V. Vaughan <gary@gnu.org>
6469 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
6470 the other gnulib imports, renamed to m4/obstack_.h.
6471 * m4/obstack.c: Updated from CVS gnulib.
6472 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
6473 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
6474 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
6475 about vpath already, and $top_srcdir upsets CVS Automake, so the
6476 $top_srcdir reference was removed.
6478 * m4/system-h.in: For consistency with the gnulib imports, renamed
6479 to m4/system_.h.
6480 * m4/Makefile (EXTRA_HEADERS): Adjust.
6481 * configure.ac (AC_CONFIG_FILES): Adjust.
6483 * m4/stdbool_.h: New file from gnulib for systems without their
6484 own.
6485 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
6486 * config/stdbool.m4: New file. Macros from gnulib for same.
6487 * configure.ac: Use it.
6489 2003-08-27 Gary V. Vaughan <gary@gnu.org>
6491 * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'`

6538 * src/main.c: Ditto.
6539 * src/stackovf.c: Ditto.
6541 * config/gmp.m4 (M4_AC_LIB_GMP): Use AC_INCLUDES_DEFAULT:
6542 ac_default_headers is an autoconf internal variable.
6543 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
6544 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
6546 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
6547 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
6548 delta.
6550 2003-08-15 Gary V. Vaughan <gary@gnu.org>
6552 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
6553 C99 bool.
6554 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
6555 possible or faking one with a typedef. Changed all callers.
6557 2003-08-15 Gary V. Vaughan <gary@gnu.org>
6559 Still cleaning up the users' module API, by taking out the stuff
6560 that isn't used by any existing modules, and moving specialised
6561 functions out of libm4 and into the module they are used by.
6563 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
6564 * m4/utility.c (m4_skip_space): ...to here the home of its only
6565 use, made static and renamed to `skip_space'. Changed all
6566 callers.
6567 * m4/m4module.h (m4_expand_ranges): Removed prototype.
6568 * m4/utility.c (m4_expand_ranges): Moved definition from here...
6569 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
6570 ltdl.
6571 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
6572 casting .
6573 * modules/gnu.c (builtin_syntax): Import and use in this
6574 builtin implementation.
6575 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
6576 Not used. Deleted.
6577 * m4/macro.c (trace_flush): Except here where the macro is now
6578 manually inlined.
6579 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
6580 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
6581 moved...
6582 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
6583 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
6585 2003-08-14 Gary V. Vaughan <gary@gnu.org>
6587 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
6588 compiler based AC_CHECK_HEADER that was introduced in
6589 autoconf-2.56.
6590 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
6591 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
6592 * configure.ac: Use renamed M4_AC_LIB_GMP.
6594 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
6595 macro that requires arguments! This stops the shell's bad
6596 substitution error at configure time.
6598 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
6599 variables to the testsuite shell. Set the value of USE_GMP so
6600 that the gmp test will run!
6601 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
6603 2003-08-11 Gary V. Vaughan <gary@gnu.org>
6605 Libltdl already has an excellent mechanism for accessing C symbols
6606 in modules. Lets use that! Remove all the exporting cruft and
6607 just use lt_dlsym in conjunction with a few conventions to
6608 simplify module writers' jobs. Also removed the table address
6609 caching code and otherwise simplified the module loader quite a
6610 bit. To access exported symbols in other modules, first the
6611 exporting module must name the symbols <modname>_LTX_<symname>,
6612 and the importing module must define a function type called
6613 <symname>_func. The importer then adds
6614 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
6615 that wishes to call out to the exported functions. Care must be
6616 taken that <symname> is non-NULL in the importing module incase
6617 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
6618 definition was in the importers source. Study
6619 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
6620 m4_module_import will attempt to automatically load a module
6621 required for symbol access if it is not loaded already.
6623 * TODO: Removed the items fixed in this delta.
6624 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
6625 module name.
6626 * m4/ltdl.h (lt_dlhandle_find): Declare it.
6627 * m4/module.c (m4_module_unload): Use it.
6628 * src/freeze.c (reload_frozen_state): Ditto.
6629 * m4/m4module.h (m4_export): Deleted. Removed all references.
6630 (M4_MODULE_IMPORT): New user convenience macro for importing
6631 arbitrary symbols from other modules.
6632 * m4/module.c (m4_module_import): New function to service
6633 M4_MODULE_IMPORT macro.
6634 (module_data): Removed. Looking up the tables on demand with
6635 lt_dlsym, rather than caching their addresses here simplifies the
6636 code substantially.
6637 (m4_get_module_builtin_table, m4_get_module_macro_table):
6638 Removed. Changed all callers.
6639 (set_module_macro_table, set_module_builtin_table): Renamed to
6640 install_macro_table and install_builtin_table respectively, and
6641 simplified now that the cache is no more.
6642 * modules/gnu.c (builtin_symbols): Use this new mechanism to
6643 import m4_dump_symbols from the m4 module.
6644 (builtin_esyscmd): Likewise for m4_set_sysval and
6645 m4_sysval_flush.
6646 * modules/m4.c (m4_export_table): Removed. Functions are
6647 addressed with the new mechanism which doesn't need this.
6648 (m4_set_sysval): New exported accessor function to prevent
6649 problems with variable access on inferior architectures.
6650 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
6651 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
6652 that we can have some type safety.
6653 * modules/modtest.c (export_test): C level exported function for
6654 testing the new import mechanism.
6655 * modules/import.c: New file for the import end of the test.
6656 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
6657 * tests/modules.at: New test cases for intermodule symbol
6658 importing.
6660 2003-08-07 Gary V. Vaughan <gary@gnu.org>
6662 * m4/m4module.c (m4_string): Moved from here...
6663 * m4/m4private.c (m4_string): ...to here.
6665 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
6667 2003-07-29 Gary V. Vaughan <gary@gnu.org>
6669 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
6670 already available to module writers through
6671 m4_{get,set}_nesting_limit_opt(), so moved from here...
6672 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
6673 (m4_create): Use it.
6675 2003-07-28 Gary V. Vaughan <gary@gnu.org>
6677 Aside from auditing path.c for m4module.h api obfuscation, this
6678 delta introduces the concept of private struct members in opaque
6679 data types to GNU m4: See the STYLE file for details.
6681 * TODO: Remind ourselves that a rewrite of path.c is needed.
6682 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
6683 Moved from here...
6684 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
6685 here and renamed. These type definitions are for internal api use
6686 only. Changed all callers.
6687 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
6688 Moved from here...
6689 * m4/path.c (search_path_env_init, search_path_add): ...to here
6690 and renamed. These calls were never used outside this file.
6691 Changed all callers.
6692 (dirpath): Moved functionality of this static declaration...
6693 * m4/m4private.h (struct m4): ...to this new internal only
6694 search_path field. Changed all callers.
6695 (m4__get_search_path): Added new internal api accessor.
6696 * m4/path.c (m4_search_path_info_new): Removed. Not used.
6697 (m4_include_init): Removed...
6698 * m4/m4.c (m4_create): ...because the new m4 field is now
6699 initialised here.
6700 (m4_delete): Recycle search_path memory.
6701 * src/main.c (main): Don't call m4_include_init now that it's
6702 gone!
6703 * doc/STYLE: Document convention for private fields in opaque
6704 ADTs.
6706 2003-07-24 Gary V. Vaughan <gary@gnu.org>
6708 Sometimes exporting the address of a symbol from a module isn't
6709 enough for other modules to call that symbol correctly. If
6710 custom data types are used for function parameters, they need to
6711 be known to the caller. This change introduces the concept of
6712 $(prefix)/include/modules/$(modulename).h to declare those
6713 structures. Also we move m4_dump_symbols from libm4 to the m4
6714 module to show this concept in action.
6716 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
6717 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
6718 exporting data structures from modules/m4.c.
6719 * modules/m4.c, modules/gnu.c: Include it.
6720 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
6721 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
6722 prototypes.
6723 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
6724 Moved from here...
6725 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
6726 ...to here, with slight renaming.
6727 (m4_export_table): Prototype and add m4_dump_symbols.
6728 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
6729 definition of m4_dump_symbols.
6730 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
6731 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
6733 2003-07-24 Gary V. Vaughan <gary@gnu.org>
6735 Create an export table in modules/m4.c in readiness for beefing up
6736 the module loader to track module exports and imports.
6738 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
6739 * m4/debug.c (m4_debug_flush_files): Moved...
6740 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
6741 * modules/gnu.c (builtin_esysval): Use it.
6742 * m4/m4module.h (m4_export): New type for declaring module symbols
6743 for export.
6744 * modules/m4.c (m4_export_table): List symbols exported from this
6745 module for use by other modules.
6747 2003-07-24 Gary V. Vaughan <gary@gnu.org>
6749 An experiment: There is loads of code in libm4 which should be in
6750 the m4 module, but is also used by another module. Just because
6751 some linkers won't cope with calls across dynamic runtime loaded
6752 objects I initially left the code in libm4. It will tidy the
6753 module api immensely if this code moves to the right place, I just
6754 need to remember to invent a suitable calling mechanism at some
6755 point. For now, only modules that are statically linked and
6756 preloaded will get this treatment, so the only platforms that will
6757 break are those that require all symbols to be resolved at link
6758 time.
6760 * TODO: Reminder that what I am doing could reduce portability
6761 unless I do something more robust later.
6762 * m4/m4module.h (m4_sysval): No longer exported from libm4.
6763 * m4/utility.c (m4_sysval): No longer declared in libm4.
6764 * modules/Makefile.am: Reformatting.
6765 * modules/m4.c (m4_sysval): Declare it at place of use.
6766 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
6768 2003-07-23 Gary V. Vaughan <gary@gnu.org>
6770 * m4/m4module.h: Reformatting and rearranging lines a bit.
6771 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
6772 all users.
6773 (m4_call_macro, m4_expand_input): Renamed...
6774 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
6775 callers.
6776 (m4_expansion_level, m4_process_macro): Moved...
6777 * m4/macro.c (expansion_level, process_macro): ...to here, and
6778 made static.
6780 * m4/m4module.h (program_name): Not used by modules at all, so
6781 moved...
6782 * src/main.c (program_name): ...to here.
6783 (print_program_name): Renamed...
6784 (print_program_name_CB): ...to conform to the STYLE guide.
6786 2003-07-23 Gary V. Vaughan <gary@gnu.org>
6788 More refactoring of the m4module.h API. Replace #defines with an
6789 enum, and move non-public functions out of the public API.
6791 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
6792 inclusion.
6793 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
6794 * m4/debug.c (m4_debug, trace): Moved...
6795 * m4/m4private.h (struct m4): ...to fields of this struct.
6796 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
6797 for the new fields.
6798 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
6799 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
6800 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
6801 * m4/m4module.h (m4_context_field_table): Add entries for new
6802 debug_file and trace_messages fields.
6803 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
6804 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
6805 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
6806 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
6807 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
6808 (m4_is_debug_bit): New macro to simplfy checks against the debug
6809 bits above.
6810 (m4_trace_format, m4_trace_header, m4_trace_flush)
6811 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
6812 prototypes.
6813 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
6814 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
6815 * m4/macro.c (trace_format, trace_header, trace_flush)
6816 (trace_prepre, trace_pre, trace_post): ...to these newly static
6817 functions, since they are only ever used from this file. Changed
6818 all callers.
6820 2003-07-17 Gary V. Vaughan <gary@gnu.org>
6822 Change the macros for checking syntax so that matching against
6823 multiple possible syntax classes can be done with a single
6824 comparison some of the time. The various classes are now bits of
6825 an int that can be checked with bitwise logic operators.
6827 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
6828 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
6829 (M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)
6830 (M4_SYNTAX_ASSIGN, M4_SYNTAX_ALPHA, M4_SYNTAX_NUM)
6831 (M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)
6832 (M4_SYNTAX_ECOMM): Replaced #defines with an enum.
6833 (M4_SYNTAX_ALNUM): Removed. Changed all callers.
6834 (M4_IS_IGNORE, M4_IS_OTHER, M4_IS_SPACE, M4_IS_OPEN, M4_IS_CLOSE)
6835 (M4_IS_COMMA, M4_IS_DOLLAR, M4_IS_ACTIVE, M4_IS_ESCAPE)
6836 (M4_IS_ASSIGN, M4_IS_ALPHA, M4_IS_NUM, M4_IS_LQUOTE, M4_IS_RQUOTE)
6837 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
6838 Replace all calls with invocations of these...
6839 (m4_is_syntax, m4_has_syntax): ...New macros.
6840 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
6841 is no longer required with new macros. Changed all callers.
6843 2003-07-15 Gary V. Vaughan <gary@gnu.org>
6845 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
6846 values are returned as part of the internal interface, so they
6847 need to be moved...
6848 * m4/private.h: ...to here.
6849 * m4/macro.c (expand_token): Check for out of range
6850 m4_peek_input() results before looking up in the syntax table.
6851 (collect_arguments): Ditto.
6853 * NEWS: Note `$' syntax class.
6855 2003-07-08 Paul Eggert <eggert@twinsun.com> and
6856 Gary V. Vaughan <gary@gnu.org>
6858 Conform to POSIX if the POSIXLY_CORRECT environment is set.
6859 --traditional `define' now smashes all the definitions.
6861 * NEWS: Explain this.
6862 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
6863 (Extensions): Explain that extensions that are incompatible with
6864 POSIX are disabled if POSIXLY_CORRECT is set.
6865 (Incompatibilities): Remove.
6866 (Define, Other Incompat): Explain difference
6867 between GNU and POSIX behavior of define, pushdef, popdef.
6868 * m4/m4.c (m4_get_posixly_correct_opt): New undef.
6869 * m4/m4module.h (m4_context_opt_bit_table): Add POSIXLY_CORRECT entry.
6870 * m4/m4private.h (M4_OPT_POSIXLY_CORRECT_BIT): New macro.
6871 (m4_get_posixly_correct_opt): New macro.
6872 * m4/m4macro.c (m4_process_macro): Disable $10, $abc etc. if
6873 POSIXLY_CORRECT.
6874 * modules/m4.c (builtin_functions): defn now takes any number of args.
6875 (builtin_define): Smash all the definitions if
6876 POSIXLY_CORRECT.
6877 (builtin_defn)): Allow any number of arguments.
6878 (builtin_undivert): Do not allow nonnumeric arguments
6879 if POSIXLY_CORRECT.
6880 * src/main.c (main): Set posixly-correct behavior if either
6881 POSIXLY_CORRECT is set, or if -G is given.
6882 * tests/builtins.at: New test for smashed definitions.
6884 2003-06-27 Gary V. Vaughan <gary@gnu.org>
6886 * doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
6887 * m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
6888 not to slow the parser down.
6889 (M4__IS_STRING): New macro to test string syntax class membership.
6890 * m4/syntax.c: Adjust docucomment.
6891 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
6892 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
6893 * m4/input.c (init_builtin_token): Comment typo.
6894 (m4__next_token): Comment typo.
6895 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
6896 by using the new M4__IS_STRING macro.
6897 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
6898 variable references in macro expansions.
6900 * doc/m4.texinfo (Eregexp and Regexp): Typo.
6901 (Epatsubst and Patsubst): Typo.
6902 (Eval): Typo.
6904 2003-06-26 Gary V. Vaughan <gary@gnu.org>
6906 Move the global variables that pertain to syntax to a new `struct
6907 m4_syntax_table', and then add one of these to `struct m4'. The
6908 ripple effect through the code to both change formerly global
6909 references, and make sure a suitable context is available in
6910 lexical scope is disproportionately large compared to the size of
6911 the change proper. This change is a large part of decoupling
6912 syntax.c from the rest of the code that uses it.
6914 * m4/m4private.h (struct m4): Add a syntax field.
6915 * m4/m4.c (m4_create): Initialise it,
6916 (m4_delete): Recycle it.
6917 (m4_get_symtab): Remove hand coded version...
6918 (m4_get_symbol_table): ...and generate this with cpp. Changed all
6919 callers.
6920 * m4/m4module.h (m4_context_field_table): Add an extra field so we
6921 can generate m4_get_symbol_table. Add a new row for
6922 m4_get_syntax_table.
6923 (M4SYNTAX): Syntactic sugar for module writers.
6924 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
6925 (m4_syntax_table): New home for syntax related formerly global
6926 variables.
6927 * m4/m4private.h (struct m4_syntax_table): Define it.
6928 * m4/input.c (m4_input_init): Initialisation of these formerly
6929 global variables moved...
6930 * m4/syntax.c (m4_syntax_create): ...to here.
6931 * m4/input.c (m4_input_exit): And similarly, recycling of the
6932 memory used by those values moved...
6933 * m4/syntax.c (m4_syntax_delete): ...to here.
6934 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
6935 Moved to m4/m4private.h.
6936 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
6937 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
6938 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
6939 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
6940 objects. Changed all callers that used to directly access the
6941 global equivalents.
6942 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
6943 Removed and incorporated into m4_syntax_table structure.
6944 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
6945 * m4/syntax.c (m4_set_syntax): Now returns an error status,
6946 instead of requiring a `struct m4' to generate its own errors.
6947 Changed all callers.
6948 * src/main.c (main): Now that the syntax table is initialised as
6949 part of m4_create, we have to manually wipe the syntax entries if
6950 we are about to read a frozen file.
6952 2003-06-26 Gary V. Vaughan <gary@gnu.org>
6954 * doc/STYLE: Added notes on callback naming schemes.
6956 * m4/module.c (m4_set_module_macro_table)
6957 (m4_set_module_builtin_table): Declarations weren't changed when
6958 definitions were renamed on 2003-06-19.
6960 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
6961 neither used nor particularly appropriate since it exposes the
6962 internal workings of the hash module. I haven't yet decided
6963 whether to remove it entirely.
6965 2003-06-20 Gary V. Vaughan <gary@gnu.org>
6967 Two related changes, and a huge knockon effect throughout the
6968 source: Moved the option variables out of global space and into
6969 `struct m4'; made `m4_symtab' a real datatype, so that its api
6970 is not marred passing `struct m4' around just so it can decide
6971 whether to keep traced symbol names or not. Added setters and
6972 getters for the formerly global option variables, and obviously
6973 changed a vast number of functions to take a `struct m4' and use
6974 the getter funcs to find option values.
6976 * m4/utility.c (interactive, sync_output, debug_level)
6977 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
6978 (max_debug_argument_length, warning_status, nesting_limit)
6979 (discard_comments): Removed.
6980 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
6981 (debug_level, max_debug_argument_length, prefix_all_builtins)
6982 (suppress_warnings, discard_comments, interactive, sync_output):
6983 Removed from here...
6984 * m4/m4private.h (struct m4): ...and equivalent fields added to
6985 this structure.
6986 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
6987 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
6988 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
6989 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
6990 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
6991 macros for the new fields.
6992 * m4/m4module.h (m4_context_field_table)
6993 (m4_context_opt_bit_table): Helper macros used to generate
6994 prototypes, setters and getters for new option fields
6995 consistently.
6996 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
6997 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
6998 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
6999 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
7000 (m4_get_interactive_opt, m4_get_sync_output_opt)
7001 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
7002 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
7003 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
7004 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
7005 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
7006 setter and getter functions generated by cpp from
7007 m4_context_field_table and m4_context_opt_bit_table, exported as
7008 part of the module api. Changed all callers.
7009 * m4/symtab (struct m4_symtab): Used as the concrete type for
7010 m4_symtab now.
7011 (m4_symtab_create): Allocate and initialise a new struct.
7012 (m4_symtab_apply): New function that works like m4_hash_apply, but
7013 with different callbacks specific to symbol tables. Changed all
7014 callers.
7015 (symbol_destroy, arg_destroy, arg_copy): Renamed
7016 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
7017 they have unused parameters for a reason!
7018 (dump_symbol_CB): New callback to dump the contents of a single
7019 symbol.
7020 (symtob_dump): Rewritten in terms of dump_symbol_CB.
7021 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
7022 Changed all callers.
7023 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
7024 of the contained `m4_symtab' at the `no_gnu_extensions' field.
7025 Although I'm not convinced these semantics are correct, they are
7026 at least consistent with how things were before this delta. Also
7027 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
7029 2003-06-19 Gary V. Vaughan <gary@gnu.org>
7031 Tie down the interface to libm4 some more. Make more structures
7032 opaque to modules by moving them to m4private.h, and writing
7033 setters and getters. To win back the speed penalty for doing this
7034 also wrote macroized versions that do know about structure layout
7035 in m4private.h and #include that file into modules when NDEBUG is
7036 defined at compile time. There are still some accessor macros in
7037 m4private.h that need to go, but that is not necessary to clean
7038 the module api up.
7040 * m4/m4module.h (m4_symbol_type): Moved...
7041 * m4/m4private.h (m4__symbol_type): ...to here.
7042 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
7043 (m4_set_symbol_traced, m4_set_symbol_name_traced)
7044 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
7045 (m4_get_symbol_func, m4_symbol_value_create)
7046 (m4_symbol_value_delete, m4_set_symbol_value_text)
7047 (m4_set_symbol_value_func): New exported api to symbols.
7048 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
7049 and m4_is_symbol_value_func.
7050 * m4/m4module.h: Prototype these guys.
7051 * m4/module.c (m4_set_module_macro_table)
7052 (m4_set_module_builtin_table): Make these static, there is no
7053 reason to pollute the api with them.
7054 * m4/m4private.h: Reformatting.
7055 (m4_get_symtab): Only define when NDEBUG is defined.
7056 (m4_get_symbol_value, m4_get_symbol_traced)
7057 (m4_set_symbol_traced, m4_set_symbol_name_traced)
7058 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
7059 (m4_get_symbol_func, m4_symbol_value_create)
7060 (m4_symbol_value_delete, m4_set_symbol_value_text)
7061 (m4_set_symbol_value_func): Macro implementations of the new
7062 functions when NDEBUG is defined.
7063 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
7064 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
7065 Superceded by the above. All callers changed.
7066 (M4ARG): Removed. This is no longer different to the
7067 m4/m4module.h definition.
7068 * modules/gnu.c, modules/m4.c: Only include m4private.h when
7069 NDEBUG is defined. That way we exercise the same (albeit slower)
7070 api that external modules must use.
7072 2003-06-18 Gary V. Vaughan <gary@gnu.org>
7074 Renamed some of the types and their accessors to make more sense.
7075 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
7076 has a stack of SYMBOL_VALUEs.
7078 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
7079 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
7080 m4_get_symbol_value_type, m4_get_symbol_value_text,
7081 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
7082 Changed all callers.
7083 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
7084 (m4_get_token_type): Renamed
7085 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
7086 to the internal api.
7087 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
7088 s/TOKEN_/VALUE_/
7089 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
7090 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
7091 (m4__token_type): Moved here from m4module.h.
7092 (m4__next_token): Renamed from m4_next_token.
7093 * m4/symtab.c: Removed some of the parameterised macro support
7094 functions for modularisation later.
7095 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
7096 m4_hash_dup to perform a true deep copy of the SRC.
7097 (arg_copy): Callback for m4_symbol_value_copy.
7098 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
7099 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
7100 m4_get_symbol_value_func. Changed all callers.
7102 2003-06-18 Gary V. Vaughan <gary@gnu.org>
7104 Tidy up style of hash.[ch] in accordance with doc/STYLE.
7106 * m4/hash.c: Internal symbol renaming and formatting.
7107 (m4_hash_dup): New function to facilitate deep copies of hash
7108 tables.
7109 (m4_hash_apply_func): Returns a void* now, which is a richer type
7110 for returning exceptions (NULL means keep going).
7111 (m4_hash_apply): Ditto.
7112 * m4/hash.h: Declare exported symbols with an explicit extern.
7113 Reformated.
7115 2003-06-17 Gary V. Vaughan <gary@gnu.org>
7117 Still refactoring furiously. This delta represents a change in
7118 semantics to symtab.c. Instead of building temporary m4_tokens
7119 in the caller, and copying fields in the methods, we now create
7120 the actual m4_token for hashing in the caller so the methods just
7121 slot them in directly. Also, this means that we don't lookup a
7122 symbol and get back an allocated but VOID token to copy fields
7123 into, we create the token we want to push and pass that to
7124 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
7125 a few other small changes to stop knowledge of the implementation
7126 of symtab.c leaking out into other files.
7128 * m4/macro.c (expand_argument): Comment typo corrected.
7129 * m4/symtab.c (symtab_fetch): New function to fetch the address of
7130 an interned symbol.
7131 (m4_symbol_pushdef): Take an extra value parameter and use this
7132 directly as the new top of the value stack. All callers changed
7133 to build a token and pass responsibility for memory in, rather
7134 than copying as we used to.
7135 (m4_symbol_define): Also use the new value parameter directly as a
7136 replacement for the top of the value stack. All callers changed
7137 to build a token as above.
7138 (m4_set_symbol_traced): New function to set the traced bit on the
7139 named symbol, creating it if necessary.
7140 (symbol_popval): The guts of the old m4_symbol_popdef.
7141 (m4_symbol_popdef): Use it.
7142 * m4/builtin.c (m4_symbol_set_token): Removed,
7143 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
7144 replaced...
7145 * m4/module.c (m4_set_module_builtin_table)
7146 (m4_set_module_macro_table): ...with these more orthogonal
7147 functions.
7148 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
7149 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
7150 required.
7151 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
7152 (m4_arg_signature_parse): Moved...
7153 * m4/symtab.c: ...to here.
7154 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
7155 screw something up. Moved...
7156 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
7157 actually does a proper deep copy of source to dest.
7159 2003-06-16 Gary V. Vaughan <gary@gnu.org>
7161 Further refactoring to stabilise the module API. Renaming some
7162 functions for orthogonality, and judicious definition migration to
7163 move things out of the set of exported symbols.
7165 * doc/STYLE: New file. Notes on coding style.
7166 * m4/m4module.c: Updated bitrotted docucomment at the top of the
7167 file.
7168 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
7169 m4_get_module_name, m4_get_module_builtin_table,
7170 m4_get_module_macro_table which are verb phrases. Changed all
7171 callers.
7172 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
7173 Moved to...
7174 * m4/module.c (m4_set_module_builtin_table)
7175 (m4_set_module_macro_table): ...here, and renamed. Changed all
7176 callers.
7177 * m4/m4module.c (m4_module_data): This...
7178 * m4/m4private.c (struct m4_module_data): ...and this...
7179 * m4/module.c (module_data) ...consolidated here and no longer
7180 exported. Changed all callers.
7182 2003-06-16 Gary V. Vaughan <gary@gnu.org>
7184 Begin work on lifting the curse of the global variables. To start
7185 with create a `struct m4' context container, and replace
7186 `m4__symtab' with `context->symtab' throughout. This means
7187 initialising a context container in main, and adjusting many
7188 functions between main and the module entry points so that the
7189 container gets passed through. It would have been nice to
7190 defer this until after 1.5, but it has a major effect on the
7191 user's module writing ABI, so it needs to be addressed now - at
7192 least in the areas that impact the ABI. An interrelated change
7193 in the symtab API removes the dependency on a global symbol table,
7194 and instead focuses on a passed table (from the context
7195 container).
7197 * TODO: Reminders for finishing context functionality.
7198 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
7199 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
7200 global variables and eventually allow m4 to be reentrant.
7201 * m4/m4private.h (m4): Define the new structure here...
7202 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
7203 don't carry the overhead of a function call.
7204 * m4/m4module.h: Prototype extern functions from m4/m4.c.
7205 (m4): Declare type for new struct m4 objects.
7206 (M4SYMTAB): User macro to ease finding the symbol table for the
7207 current context for module developers.
7208 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
7209 verb.
7210 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
7211 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
7212 (m4_call_macro, m4_dump_symbols, m4_expand_input)
7213 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
7214 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
7215 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
7216 m4* context parameter. Changed definitions and all callers.
7217 (m4_symtab): Alias for m4_hash to decouple the
7218 m4_symtab api from m4_hash.
7219 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
7220 m4_hash.
7221 (m4_symtab_create): New function to return an initialised
7222 m4_symtab.
7223 (m4_symtab_delete): New function to delete an m4_symtab's memory.
7224 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
7225 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
7226 instead of simply using the global m4__symtab. Changed
7227 definitions and all callers.
7228 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
7229 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
7230 * src/main.c (main): Create a context and use that instead of the
7231 former global m4__symtab.
7233 2003-06-13 Gary V. Vaughan <gary@gnu.org>
7235 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
7236 to the callback. Callbacks should not need to hardcode the
7237 hashtable they are working from, nor should we have to waste the
7238 userdata parameter to pass the table in.
7239 * m4/hash.h (m4_hash_apply_func): Require the initial table
7240 parameter.
7241 * m4/symtab.c (symtab_destroy): Use the passed table instead
7242 of hardcoding m4__symtab.
7243 (m4_symbol_popdef): Don't use the userdata parameter to pass the
7244 table to arg_destroy.
7245 (arg_destroy): Use the hash parameter, ignore userdata.
7246 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
7247 prototype.
7248 (traceon, traceoff): Call set_trace with the extra initial
7249 parameter.
7251 2003-06-13 Gary V. Vaughan <gary@gnu.org>
7253 More refactoring to stabilise the module api, this time for
7254 symtab.c. Additionally, start to pay attention to function names
7255 that don't contain a verb like they should.
7257 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
7258 wrapper for m4_hash_apply to decouple the symtab module from the
7259 hash module.
7260 (m4_symbol_builtin, m4_symbol_macro): Renamed to
7261 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
7262 callers.
7263 (m4_symbol_delete): Create a macro version to save a function
7264 call.
7265 (m4_token_t, m4_data_t): These violate the POSIX reserved
7266 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
7267 all callers.
7268 (m4_token_type): Renamed to m4_token_get_type.
7269 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
7270 (m4_symtab_exit): Removed from the exported module
7271 api...
7272 * m4/m4private.h (m4__symtab, m4__symtab_init)
7273 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
7274 renamed and added to the internal api. Changed all callers.
7275 (m4_symtab_apply): A faster macro version of the function for
7276 users of the internal api.
7277 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
7278 symbol_destroy and arg_destroy.
7279 (symtab_debug): Added a prototype.
7280 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
7281 so that callers in this file get the faster macro versions from
7282 m4/m4private.h.
7284 2003-06-12 Gary V. Vaughan <gary@gnu.org>
7286 Refactoring modules to rationalise the API into an external
7287 documented (eventually!) API for use by modules in the `m4_'
7288 namespace declared in m4/m4module.h, an internal API between the
7289 source files we ship (including our shipped modules) in the `m4__'
7290 namespace declared in m4/m4private.h and making the rest as
7291 cohesive as possible with liberal use of the `static' keyword.
7292 This change represents an audit to m4/module.c along these
7293 guidelines.
7295 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
7296 Removed. No longer used.
7297 (m4_module_close): Removed prototypes.
7298 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
7299 from the exported module api...
7300 * m4/m4private.h (m4__module_init, m4__module_open)
7301 (m4__module_exit): ...and renamed and added to the internal api.
7302 Changed all callers.
7303 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
7304 Centralised definitions after renaming...
7305 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
7306 (M4_FINISH_SYMBOL): ...and removing from here.
7307 (m4_module_dlerror, m4_module_remove, m4_module_close)
7308 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
7309 module_remove, module_close and caller_id.
7310 (MODULE_SELF_NAME): New macro to make reporting self errors
7311 easier.
7312 (m4_module_load, module_close, module_remove): Use it.
7313 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
7314 name.
7315 * src/main.c (main): Use it.
7317 2003-06-12 Gary V. Vaughan <gary@gnu.org>
7319 * README: Remove references to --enable-changeword, which has been
7320 removed from the code.
7322 2003-06-11 Gary V. Vaughan <gary@gnu.org>
7324 Getting rid of the annoying bug with configure --enable-debug,
7325 which spewed -e: command not found errors. This was an interaction
7326 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
7327 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
7328 branch-1-5) to get the full fix.
7330 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
7331 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
7332 and then use the probed value of $SED.
7333 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
7334 this, it messes up the AC_REQUIRE stack.
7336 2003-06-10 Gary V. Vaughan <gary@gnu.org>
7338 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
7339 the destroy callback.
7340 (m4_arg_destroy): Use the hash address to free the hash node key
7341 field.
7343 2003-06-06 Gary V. Vaughan <gary@gnu.org>
7345 First cut at formal parameters in macros.
7347 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
7348 * m4/xstrzdup.c: New file.
7349 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
7350 associative array of parameter names to details.
7351 (m4_symbol_token): Capture macro names with parameter lists.
7352 (m4_arg_signature_parse): And build an associative array to hang
7353 from the symbol structure to map names to details.
7354 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
7355 m4_hash_resize idiom. Now that we potentially add a little hash
7356 table to many of the entries in the symbol table, added an extra
7357 arg to set the initial size. Changed all callers.
7358 (m4_hash_apply): New function that is basically a generalised
7359 version of...
7360 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
7361 all callers to call m4_hash_apply instead.
7362 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
7363 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
7364 m4_arg_signature association that might be attached to the symbol,
7365 * m4/hash.h (m4_hash_apply_func): Replacement type for...
7366 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
7367 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
7368 parameter lists.
7369 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
7370 (M4_IS_IDENT): Detect characters that can be safely used in
7371 parameter names.
7372 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
7373 * m4/macro.c: Corrected grammar in some comments. Use `token'
7374 rather than `td' for m4_token variables.
7375 (m4_process_macro): If we find a dollar followed by some
7376 M4_IS_IDENT characters, replace that with the contents of the argv
7377 entry with offset stored in the m4_token_arg associated with the
7378 collected identifier.
7380 2003-06-05 Gary V. Vaughan <gary@gnu.org>
7382 Begin preparations for supporting formal parameters in m4 macros.
7384 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
7385 the details of a formal parameter.
7386 (m4_token): Add an arg_signature member to hold a hash table for
7387 looking up formal parameters.
7388 * m4/input.c: Update more bitrotted comments.
7389 (m4_push_builtin): Initialise arg_signature member.
7390 (init_builtin_token): Copy arg_signature member.
7391 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
7392 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
7393 replace...
7394 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
7395 (m4_macro_pushdef, m4_macro_define): ...these, And...
7396 (m4_symbol_token): ...wrapped around this new function, which
7397 vastly simplifies the arguments required by the functions it
7398 replaces.
7399 Changed all callers.
7401 2003-06-05 Gary V. Vaughan <gary@gnu.org>
7403 * m4/macro.c: Format changes.
7405 2003-06-04 Gary V. Vaughan <gary@gnu.org>
7407 * m4/input.c: Updated various bitrotted comments.
7408 (m4_push_builtin): Just pass the whole m4_token, rather than
7409 extracting all the fields in the caller. This also allows us to
7410 check the token type for consistency.
7411 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
7412 Renamed to builtin_funcs, builtin_peek, builtin_read,
7413 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
7414 the code. Changed all callers.
7415 (struct input_block): Similarly renamed u_m member to u_b, and
7416 changed all callers.
7417 (m4_next_token): Use bzero to initialise the data fields.
7418 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
7420 2003-05-29 Gary V. Vaughan <gary@gnu.org>
7422 These changes were necessary to get m4 to build on my iBook
7423 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
7424 (GCC) 3.1 20020420 (prerelease)":
7426 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
7427 inclusion of module loader headers.
7428 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
7429 * m4/Makefile.am: Ditto.
7430 (libm4_la_LIBADD): Added $(LTLIBINTL).
7431 * m4/utility.c (program_name): Removed declaration in favour of
7432 the one already in error.c!
7433 * m4/m4module.h (program_name): Define to program_invocation_name
7434 when using GNU C library. Use an explicit extern declaration.
7435 (interactive, sync_output, debug_level, hash_table_size)
7436 (no_gnu_extensions, prefix_all_builtins, max_debug_argument_length)
7437 (suppress_warnings, warning_status, nesting_limit, discard_comments)

7445 (m4_current_line, m4_current_diversion, m4_output_current_line):
7446 Don't rely on default, use an explicit extern.
7447 * m4/error.h (error, error_at_line, error_print_progname)
7448 (error_message_count, error_one_per_line): Ditto.
7449 * m4/ltdl.c: Update from CVS libtool.
7450 * m4/ltdl.h: Ditto.
7451 * commit: Update from CVS cvs-utils.
7453 2002-11-04 gettextize <bug-gnu-gettext@gnu.org>
7455 * po/Makefile.in.in: Upgrade to gettext-0.11.5.
7456 * po/boldquot.sed: New file, from gettext-0.11.5.
7457 * po/en@boldquot.header: New file, from gettext-0.11.5.
7458 * po/en@quot.header: New file, from gettext-0.11.5.
7459 * po/insert-header.sin: New file, from gettext-0.11.5.
7460 * po/quot.sed: New file, from gettext-0.11.5.
7461 * po/remove-potcdate.sin: New file, from gettext-0.11.5.
7462 * po/Rules-quot: New file, from gettext-0.11.5.
7464 2002-11-04 Akim Demaille <akim@epita.fr>
7466 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
7467 running m4 itself.
7468 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
7470 2002-11-04 Akim Demaille <akim@epita.fr>
7472 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
7474 2002-11-04 Akim Demaille <akim@epita.fr>
7476 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
7477 used as `external', and Libtool 1.4.3.
7478 (LINGUAS): Remove.
7479 (LTLIBOBJS): Don't play with it.
7480 * intl/: Remove.
7481 * Makefile.am (SUBDIRS): Remove intl.
7482 (ACLOCAL_AMFLAGS): Add -I config.
7483 (EXTRA_DIST): Add config/config.rpath.
7484 * po/LINGUAS: New.
7485 * po/Makevars: New.
7486 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
7488 2002-05-29 Gary V. Vaughan <gary@gnu.org>
7490 Preparations for refactoring syntax tables to allow reverse
7491 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
7492 speed of normal lookups in an array of unsigned short.
7494 * m4/input.c (single_quotes, single_comments, use_macro_escape):
7495 Moved from here...
7496 * m4/m4private.h (m4__single_quotes, m4__single_comments,
7497 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
7498 is for internal symbols which unavoidably pollute the global
7499 namespace, but are not published APIs.
7500 Adjusted all callers.
7501 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
7502 m4_set_comment, m4_set_syntax, set_syntax_internal,
7503 unset_syntax_attribute): Moved from this file...
7504 * m4/syntax.c: New. ...to this file.
7505 Also added an m4_syntax_exit stub for orthogonality.
7506 * src/main.c (main): Use it.
7507 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
7508 * m4/m4module.h: Reformatting. New prototypes.
7510 2002-05-29 Gary V. Vaughan <gary@gnu.org>
7512 * bootstrap (aclocal_apiversion): The aclocal apiversion is
7513 distinct from the automake release number (in that the apiversion
7514 apparently has no micro-version-component).
7515 (aclocal_apilibdir): Use it.
7517 2002-05-28 Gary V. Vaughan <gary@gnu.org>
7519 * m4/hash.c (m4_hash_resize): New function.
7520 * m4/hash.h: Add prototype.
7521 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
7522 benchmarking to find a good value for, say, autoconf. This is
7523 already a little quicker than before for me.
7525 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
7526 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
7527 and reenamed.
7528 * m4/hash.h: Adjust prototypes.
7530 2002-01-22 Akim Demaille <akim@epita.fr>
7532 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
7533 APIVERSION scheme.
7534 * tests/Makefile.am (package.m4): New.
7535 * tests/atlocal.in: Adjust to CVS Autotest.
7536 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
7537 * configure.ac: LIBOBJ is a forbidden string.
7538 Simplify AM_INIT_AUTOMAKE invocation.
7539 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
7540 options.m4.
7542 2002-01-21 gettextize <bug-gnu-utils@gnu.org>
7544 * po/Makefile.in.in: Upgrade to gettext-0.10.40.
7546 2001-10-19 Akim Demaille <akim@epita.fr>
7548 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
7550 2001-10-19 Akim Demaille <akim@epita.fr>
7552 * m4/input.c (m4_next_token): Display where was opened what is
7553 not closed.
7555 2001-10-19 Akim Demaille <akim@epita.fr>
7557 * m4/macro.c (expand_argument): Display where was opened what is
7558 not closed.
7560 2001-10-18 Akim Demaille <akim@epita.fr>
7562 * m4/input.c, modules/m4.c: Formatting changes.
7564 2001-10-17 Gary V. Vaughan <gary@gnu.org>
7566 * bootstrap: s/configure.in/configure.ac/
7568 2001-10-16 Gary V. Vaughan <gary@gnu.org>
7570 * m4/symtab.c (m4_symbol_destroy): This function calls
7571 m4_symbol_popdef, which recycles a symbols memory when the last
7572 definition is popped. Since we were passing the address of the
7573 symbol name found in the symbol table, and it was being removed
7574 partway through m4_symbol_destroy() we were referencing freed
7575 memory for the balance of the function. Now we take a copy of the
7576 symbol name tring and use that as a key into the symbol
7577 table... that way if the original symbol name is freed, the copy
7578 is still valid.
7580 2001-10-13 Akim Demaille <akim@epita.fr>
7582 * m4/ltdl.c: Update.
7584 2001-10-13 Akim Demaille <akim@epita.fr>
7586 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
7587 Don't gettextize internal error messages.
7589 2001-10-13 Akim Demaille <akim@epita.fr>
7591 * tests/macros.at (Arity and defn): New failing test.
7592 (Arity, defn, and freeze): New.
7594 Fix `Arity and defn'.
7596 * m4/input.c (m4_push_macro): Don't forget the arity.
7597 * modules/m4.c (defn): Likewise.
7599 2001-10-13 Akim Demaille <akim@epita.fr>
7601 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
7602 to...
7603 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
7604 (Propagation of traceon, Propagation of --trace): this new file.
7606 2001-10-13 Akim Demaille <akim@epita.fr>
7608 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
7609 interface instead of (name, argc...).
7610 Upon failure, specify which argument was guilty.
7611 Adjust callers.
7613 2001-10-13 Akim Demaille <akim@epita.fr>
7615 * modules/evalparse.c: Save translators' time: don't translate
7616 internal error messages.
7617 (m4_evaluate): Simplify/normalize error messages.
7618 * doc/m4.texinfo (Eval): Adjust.
7620 2001-10-13 Akim Demaille <akim@epita.fr>
7622 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
7623 where no checking is needed.
7624 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
7625 interface instead of (name, argc...).
7626 Adjust callers.
7627 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
7628 elsewhere.
7630 2001-10-13 Akim Demaille <akim@epita.fr>
7632 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
7633 exclude the builtin name from the count.
7634 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
7635 calling ifelse with a single argument is valid.
7636 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
7637 with 1 and 2 args, mostly to strengthen the test suite.
7639 2001-10-13 Akim Demaille <akim@epita.fr>
7641 * m4/output.c (m4_make_diversion, m4_insert_file)
7642 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
7644 2001-10-12 Gary V. Vaughan <gary@gnu.org>
7646 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
7647 since we call these things builtins in the rest of the code!
7649 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
7651 2001-10-12 Gary V. Vaughan <gary@gnu.org>
7653 Rather than forcing each builtin definition to manage its own
7654 argument range checking, tabulate the maxima and minima for all
7655 builtins in each module. This forces us to consider what the
7656 valid ranges for each builtin should be, and moves the checking
7657 code out of each builtin implementation and into the builtin
7658 caller infrastructure.
7660 * m4/m4module.h (struct m4_builtin): Add argument minima and
7661 maxima.
7662 * m4/m4private.h (struct m4_token): Reflect them here too.
7663 * m4/input.c (struct input_block): ...and here.
7664 (m4_token_copy): New function for token copying.
7665 (init_macro_token): Copy them from a token to the input stack.
7666 (m4_next_token): Don't forget to initialise them for text
7667 macros.
7668 * m4/macro.c (expand_argument): Use m4_token_copy, and also
7669 check argument counts before calling the builtin handler.
7670 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
7671 (m4_symbol_macro): Likewise.
7672 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
7673 parameters. Updated all callers.
7674 (m4_builtin_define): Ditto.
7675 (m4_macro_pushdef, m4_macro_define): Ditto.
7676 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
7677 * modules/evalparse.c: Declare argument counts for defined
7678 builtins and remove explicit calls to m4_bad_argc().
7679 * modules/gnu.c: Ditto.
7680 * modules/load.c: Ditto.
7681 * modules/m4.c: Ditto.
7682 * modules/modtest.c: Ditto.
7683 * modules/mpeval.c: Ditto.
7684 * modules/perl.c: Ditto.
7685 * modules/shadow.c: Ditto.
7686 * modules/stdlib.c: Ditto.
7687 * modules/time.c: Ditto.
7688 * TODO: Updated.
7690 2001-10-10 Gary V. Vaughan <gary@gnu.org>
7692 The trace semantics now attach the trace bit to a symbol name.
7693 For as long as a traceon(`foo') is active, calls to foo will be
7694 traced regardless of intervening undefines or module unloads.
7695 Fixed the flag propogation issues differently to the fixes
7696 reverted with the last attempt at nailing down trace:
7698 * m4/m4private.h: This file is not visible outside of the m4
7699 source tree, so I removed all the `M4_' and `m4_' prefixes to save
7700 on typing. Updated all clients.
7701 (m4_token): New typedef contains the fields that need to be passed
7702 around with the low level tokeniser.
7703 (m4_token_data): Removed.
7704 (m4_symbol): Now contains the traced flag again.
7705 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
7706 the trace bit set. This change is contained entirely within this
7707 module and doesn't leak out into the callers. Updated all
7708 clients.
7709 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
7710 new fields in m4_token. Updated all clients.
7711 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
7712 that `groks_macro_args' and `blind_if_no_args' flags are retained
7713 when defn() results are passed around in m4 code. Updated all
7714 callers.
7715 (m4_builtin_define): Ditto.
7716 (m4_macro_pushdef, m4_macro_define): Ditto.
7717 * m4/input.c (struct input_block): Add a flags field to facilitate
7718 the above.
7719 (m4_push_macro): ...use it.
7720 (init_macro_token): Retrieve it.
7721 (m4_next_token): Initialise it.
7722 * m4/macro.c (expand_argument): Copy it.
7723 * m4/m4module.h: Adjust.
7724 * tests/builtins.at: Adjust the expected output of the trace
7725 tests to reflect the change in semantics.
7726 * tests/modules.at (modules: trace): Check that unloading a
7727 module which supplies a traced symbol definition doesn't lose te
7728 trace bit.
7730 2001-10-07 Gary V. Vaughan <gary@gnu.org>
7732 * modules/gnu.c (m4_macro_table): Display the timetamp when
7733 expanding __m4_version__.
7735 * configure.ac (--with-modules): Forgot a comma in the
7736 AC_HELP_STRING parameter list.
7738 2001-10-05 Gary V. Vaughan <gary@gnu.org>
7740 * bootstrap: Remove aclocal.m4t when it is no longer required.
7742 2001-10-05 Akim Demaille <akim@epita.fr>
7744 * tests/Makefile.am: Adjust for gnuprog2.
7745 * tests/m4.in: There can be a leading path.
7746 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
7747 * tests/testsuite.at: Adjust to the most recent Autotest.
7748 (AT_CHECK_M4_FILTER): Fix and rename as...
7749 (AT_TEST_M4): this.
7750 * tests/others.at: Use it.
7752 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
7753 variable in shell scripts, one uses `$'...
7755 2001-10-04 Gary V. Vaughan <gary@gnu.org>
7757 * configure.ac: `rm -f $m4_getopt_h' was lost.
7759 2001-10-04 Gary V. Vaughan <gary@gnu.org>
7761 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
7762 time. Define it for config.h in order to...
7763 * src/main.c (main): ...display the timestamp for --version.
7765 2001-10-04 Akim Demaille <akim@epita.fr>
7767 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
7768 previous builtins `regexp' and `patsubst'.
7769 (regexp, patsubst): Use them.
7770 (eregexp, epatsubst): New builtins.
7771 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
7772 (Epatsubst and Patsubst, Eregexp and Regexp): these.
7773 (Extensions): More info on REs.
7775 2001-10-04 Akim Demaille <akim@epita.fr>
7777 * modules/modtest.c (init_handler): Consistently output to stderr.
7778 (finish_handler): New.
7779 (test): The `if' is an `assert'.
7780 * tests/modules.at: Adjust.
7782 2001-10-04 Akim Demaille <akim@epita.fr>
7784 * m4/utility.c (m4_bad_argc): Detail the mismatches.
7786 2001-10-01 Akim Demaille <akim@epita.fr>
7788 * tests/generate.awk: Tag the tests with `documentation'.
7789 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
7790 Use the make the existing modtest tests more uniform, and complete
7791 the set of possibilities.
7793 2001-10-01 Akim Demaille <akim@epita.fr>
7795 * config/gmp.m4: Consult the user before using GMP: use
7796 --without-gmp.
7797 * configure.ac: Adjust.
7798 * modules/gmp.c: No protection needed as the module is not built
7799 if GMP is not used.
7801 2001-10-01 Akim Demaille <akim@epita.fr>
7803 * tests/generate.awk: Remove debugging code.
7804 (fatal): Specify the current location.
7806 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
7807 * modules/gnu.c, modules/m4.c: Use M4ARG.
7809 2001-10-01 Akim Demaille <akim@epita.fr>
7811 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
7812 (m4_regexp_compile): New.
7813 (regexp, patsubst): Use it.
7815 2001-09-30 Gary V. Vaughan <gary@gnu.org>
7817 Reinstate the memory handling improvements from the patch I just
7818 reverted. Relevant ChangeLog entries repeated here:
7820 * m4/module.c (m4_module_remove): New function that holds the core
7821 of the old m4_module_unload.
7822 (m4_module_unload): Use it.
7823 (m4_module_unload_all): When we know the modules will never be
7824 used again (i.e. on exit), free up as much module memory as
7825 possible. There are still some artifacts from resident modules
7826 living inside ltdl.c, but everything else is freed.
7827 * m4/debug.c (m4_debug_exit): Free memory allocated in
7828 m4_debug_init().
7829 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
7830 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
7831 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
7832 * m4/m4module.h: Updated prototypes.
7833 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
7834 * m4/hash.h: Updated prototypes.
7835 * src/main.c (main): Use all these new functions to clean up as
7836 much memory as possible before exit.
7838 2001-09-30 Gary V. Vaughan <gary@gnu.org>
7840 Reverted my large patch for removing the old m4_symbol
7841 structure on 2001-09-20. We are still not happy about the way
7842 trace works in conjunction with defn and undefine, and leaving
7843 the reverted patch active prevents us from moving the traced
7844 bit from the definition back to the symbol.
7846 2001-09-30 Gary V. Vaughan <gary@gnu.org>
7848 * configure.in: Moved to...
7849 * configure.ac: ...here. Added a libtool like timestamped
7850 banner, and tidied up the libltdl cruft.
7851 * config/mkstamp: Script to extract a timestamp from ChangeLog.
7852 * modules/Makefile.am (INCLTDL): Removed. This is required
7853 only when libltdl is configured in a subdirectory.
7854 * src/Makefile.am: Ditto.
7855 (LIBADD_DL): No need to add this again, libtool already knows
7856 that libm4.la depends on it.
7857 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
7858 them.
7860 * TODO: stackovf.c is basically broken.
7861 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
7863 2001-09-28 Akim Demaille <akim@epita.fr>
7865 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
7867 2001-09-27 Akim Demaille <akim@epita.fr>
7869 * tests/m4.in: Don't use short options.
7870 Simplify the stderr signature normalization.
7872 2001-09-27 Akim Demaille <akim@epita.fr>
7874 tests/m4 shall be position independent.
7876 * tests/m4.in: New.
7877 * tests/m4: Remove.
7878 * tests/testsuite.at: No args to AT_INIT.
7879 * configure.in, tests/Makefile.am: Adjust.
7881 2001-09-22 Akim Demaille <akim@epita.fr>
7883 Autotest has changed again.
7885 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
7886 (package.m4): Remove.
7887 * configure.in: Adjust to LIBADD_GMP.
7889 2001-09-21 Gary V. Vaughan <gary@gnu.org>
7891 * config/gmp.m4 (AC_ARG_WITH): Removed.
7892 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
7893 (AC_LIB_GMP): When performing a test compile against libgmp,
7894 include the header gmp.h if possible, and link against -lgmp. If
7895 they both work define USE_GMP.
7896 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
7897 (mpeval_LTX_init_func): Complain on load that there was no libgmp
7898 at compile time.
7900 2001-09-20 Gary V. Vaughan <gary@gnu.org>
7902 * m4/evalparse.c: Moved to...
7903 * modules/evalparse.c: ...here. This code is shared between
7904 modules/mpeval.c and modules/m4.c, so there is no need to pollute
7905 the libm4 API with its details. Moderately rewritten to interface
7906 into its clients more simply.
7907 * m4/eval.c: Deleted. Migrated functionality to...
7908 * modules/m4.c: ...here.
7909 (builtin_eval): Implemented in terms of the new interface style.
7910 * modules/mpeval.c (builtin_mpeval): Ditto.
7911 * m4/m4module.h: Removed references to the former m4/eval.c.
7912 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
7913 (EXTRA_libm4_la_SOURCES): Deleted.
7914 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
7915 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
7917 2001-09-20 Akim Demaille <akim@epita.fr>
7919 * config/gmp.m4 (AM_WITH_GMP): Rename as...
7920 (AC_LIB_GMP): this.
7921 By default, use gmp.
7922 Massive revamping.
7923 * configure.in: Adjust.
7924 Use Automake conditionals for USE_GMP.
7925 Always compute sizeof (long long int).
7926 This was a bug BTW, as `eval' (not `mpeval') depends on it:
7927 before, it was used _only_ if mpeval was not activated.
7928 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
7929 (mpeval_la_LIBADD): New macros.
7930 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
7931 Indent.
7932 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
7933 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
7934 WITH_GMP.
7936 2001-09-20 Akim Demaille <akim@epita.fr>
7938 * tests/Makefile.am (package.m4): New.
7939 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
7941 2001-09-20 Gary V. Vaughan <gary@gnu.org>
7943 More cleanup. After the last patch, m4_symbol holds nothing but
7944 the head of a chain of m4_token_data. So I have removed the old
7945 m4_symbol, so that m4_token_data chains are stored directly in the
7946 value cell of a hash table node. But there's more... m4_symbol
7947 was a more natural name for the symbol value cell, and now that it
7948 is gone I have renamed the former m4_token_data structure to
7949 m4_symbol. This change turned out to be a pig to get right, since
7950 the original code didn't need to modify the value cell itself,
7951 since changing the chain happened inside the m4_symbol that used
7952 to be returned -- I had to pass the address of the value cell
7953 across various function calls, incase the head value changed. I
7954 also tightened up the memory management to help me find a nasty
7955 memory corruption bug that took me all night to track down...
7957 * m4/m4private.h (struct m4_symbol): Removed.
7958 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
7959 all references.
7960 * m4/hash.c (m4_hash_iterator_value): Return the address of the
7961 value cell. Updated all callers.
7962 * m4/symtab.c: Took advantage of the simplification in the data
7963 structures to rewrite a lot of this file more simply. There is
7964 still some room for optimisation here, but we should tackle that
7965 systematically closer to the release.
7967 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
7968 revealed. This version is ahead of CVS libtool until I get chance
7969 to flush my changes.
7970 * m4/module.c (m4_module_remove): New function that holds the core
7971 of the old m4_module_unload.
7972 (m4_module_unload): Use it.
7973 (m4_module_unload_all): When we know the modules will never be
7974 used again (i.e. on exit), free up as much module memory as
7975 possible. There are still some artifacts from resident modules
7976 living inside ltdl.c, but everything else is freed.
7977 * m4/debug.c (m4_debug_exit): Free memory allocated in
7978 m4_debug_init().
7979 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
7980 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
7981 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
7982 * m4/m4module.h: Updated prototypes.
7983 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
7984 * m4/hash.h: Updated prototypes.
7985 * src/main.c (main): Use all these new functions to clean up as
7986 much memory as possible before exit.
7988 2001-09-18 Gary V. Vaughan <gary@gnu.org>
7990 The `traced' flag needs to be attached to the definition of a
7991 symbol rather than the current symbol containing the definition.
7992 Implementing this showed up some long standing post 1.4 bugs in
7993 flag propogation which I also fixed.
7995 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
7996 (struct m4_token_data): And add it back in here.
7997 * m4/input.c (init_macro_token): Propogate the traced flag
7998 correctly.
7999 * m4/macro.c (expand_argument): Ditto.
8000 * tests/builtins.at (trace2, trace3): New tests based on Akim's
8001 sadistic email ;-)
8003 2001-09-08 Gary V. Vaughan <gary@gnu.org>
8005 * m4/m4private.h (struct m4_token_data): Simplified by removing
8006 the redundant `traced' flag, and one level of structure nesting.
8007 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
8008 * m4/input.c (init_macro_token): No need to initialise removed
8009 `traced' field.
8010 * m4/macro.c (expand_argument): No need to copy it either.
8011 * m4/utility.c (m4_token_data_func_traced): Or provide an access
8012 function.
8014 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
8015 dependant on multiple symbols with the same key, so preserving
8016 relative symbol order in each bucket during resizing is no longer
8017 required. The resize function is considerably faster as a result.
8019 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
8020 s/m4_symbol_insert/m4_symbol_define/g;
8021 s/m4_builtin_insert/m4_builtin_define/g;
8022 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
8024 2001-09-08 Gary V. Vaughan <gary@gnu.org>
8026 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
8027 commits, the m4_lookup_symbol dispatch function is split into
8028 specialised functions that must be called directly.
8030 * m4/m4module.h (m4_symbol_lookup_t): Removed.
8031 * m4/symtab.c (m4_lookup_symbol): Removed.
8032 (m4_symbol_builtin, m4_symbol_macro): New functions.
8033 * m4/builtin.c (m4_builtin_define): Split into...
8034 (m4_builtin_pushdef, m4_builtin_insert): ...these.
8035 (m4_macro_define): Split into...
8036 (m4_macro_pushdef, m4_macro_insert): ...these.
8037 * src/main.c (main): Set command line macros from `-D' parameters
8038 using `m4_macro_define'.
8040 2001-09-08 Gary V. Vaughan <gary@gnu.org>
8042 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
8043 this from m4_remove_table_reference_symbols().
8044 * m4/m4module.h, m4/module.c: Updated all references.
8046 2001-09-07 Akim Demaille <akim@epita.fr>
8048 * modules/stdlib.c, modules/times.c: Misc cleanups.
8050 2001-09-07 Akim Demaille <akim@epita.fr>
8052 * configure.in: We now need Autoconf 2.52e.
8053 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
8054 and `M4_SYMBOL_DELETE'.
8055 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
8056 * src/main.c (main): Adjust.
8058 2001-09-06 Gary V. Vaughan <gary@gnu.org>
8060 Fix the obstack.h problem once and for all! At configure time we
8061 can test for a system supplied obstack.h: depending on the
8062 result, we now generate system.h with an #include of the correct
8063 header. As a bonus, I've also added a --with-included-obstack,
8064 incase the user doesn't like the system obstack for some
8065 reason... and also we can test the shipped obstack on a system
8066 that has oe of its own. We also now need to be careful to add
8067 build directories to the include search path, since the generated
8068 system.h will be in the build tree.
8070 * configure.in (AC_CONFIG_FILES): Generate system.h from
8071 system-h.in.
8072 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
8073 include the system obstack header or the copy shipped with M4.
8074 Allow the user to override configure and force the build to use
8075 the shipped version.
8076 * m4/system-h.in: New file, template for...
8077 * m4/system.h: ...this. Now deleted.
8078 * m4/m4module.h: Include system.h before everything else.
8079 * src/freeze.c: Ditto.
8080 * m4/Makefile.am (dist-hook): Remove generated system.h.
8081 (INCLUDES): Check builddir for generated headers before checking
8082 srcdir.
8083 * modules/Makefile.am (INCLUDES): Ditto.
8084 * src/Makefile.am (INCLUDES): Ditto.
8086 2001-09-05 Gary V. Vaughan <gary@gnu.org>
8088 * TODO: Remove the items that have been addressed already.
8090 2001-09-05 Akim Demaille <akim@epita.fr>
8092 * src/main.c (main): Standardize --version.
8094 2001-09-05 Akim Demaille <akim@epita.fr>
8096 * modules/format.c (format): Have a bigger `str'.
8098 2001-09-05 Akim Demaille <akim@epita.fr>
8100 Rationalize warnings, reporting the macro name as if it were a
8101 program name, and assertions.
8103 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
8104 (M4WARN): New.
8105 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
8106 (m4_symbol_delete):
8107 Use assert for internal errors.
8108 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
8109 M4WARN.
8110 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
8111 M4WARN and assert.
8112 * tests/builtins.at (pushpop): Adjust.
8114 2001-09-05 Akim Demaille <akim@epita.fr>
8116 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
8117 with pointers.
8119 2001-09-05 Akim Demaille <akim@epita.fr>
8121 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
8122 * m4/macro.c, m4/symtab.c: Adjust.
8124 2001-09-05 Akim Demaille <akim@epita.fr>
8126 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
8127 (m4_symbol_pop, m4_symbol_del): this.
8128 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
8129 (m4_symbol_popdef, m4_symbol_delete): New.
8130 (m4_lookup_symbol): Adjust.
8131 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
8133 2001-09-05 Akim Demaille <akim@epita.fr>
8135 * m4/m4module.h (m4_symbol_lookup): Rename as...
8136 (m4_symbol_lookup_t): this.
8138 2001-09-05 Akim Demaille <akim@epita.fr>
8140 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
8141 unused.
8142 * m4/symtab.c (m4_lookup_symbol): Adjust.
8144 2001-09-03 Gary V. Vaughan <gary@gnu.org>
8146 Bootstrap will now work with Libtool 1.4.1 or higher:
8147 * bootstrap: Remove stale autom4te.cache files when
8148 rebootstrapping.
8149 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
8150 libtool.m4.
8151 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
8152 libtool.m4 directly.
8153 Run libtoolize to refresh ltmain.sh.
8154 * config/ltmain.sh: Deleted.
8155 * acinclude.m4: Deleted.
8156 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
8158 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
8159 implementation for the cvs impaired libtool user.
8161 2001-09-03 Akim Demaille <akim@epita.fr>
8163 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
8164 internal errors.
8165 Avoid using `default' in switch, as it hides useful compiler
8166 warnings when a case is forgotten.
8168 2001-09-03 Akim Demaille <akim@epita.fr>
8170 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
8171 is no such thing as `WITH_MODULES'.
8173 2001-09-03 Akim Demaille <akim@epita.fr>
8175 Improve the test suite's selfcontainedness.
8177 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
8178 (Include, Undivert): Tag the other input files.
8179 * tests/generate.awk: Catch `@comment file:'.
8180 `-I $src' is no longer needed.
8181 `next' is really like `return': the rest is skipped.
8182 Adjust to `input.m4'.
8183 (fatal): New function.
8184 * tests/foo, tests/incl.m4: Remove.
8186 2001-09-01 Gary V. Vaughan <gary@gnu.org>
8188 The shadowing mechanism and, infact, the whole symbol table
8189 implementation was creaking under the weight of the features piled
8190 on top of it. We now have a separate hash table module which will
8191 dynamically resize to keep symbol density withing good performace
8192 limits, and a new symtab module layered above it. Symbol lookups
8193 are now marginally more efficient (since the shadowed flag is no
8194 longer required) and symbol removal, such as on module unload, is
8195 considerably faster due to a reorganisation of the data structures
8196 used in symtab.c.
8198 * src/main.c (main): Don't mention `-H'.
8199 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
8200 effect.
8201 * NEWS: Updated.
8202 * m4/hash.c: New generalised dynamic hash table data structure
8203 management module.
8204 * m4/hash.h: Public interface.
8205 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
8206 (libm4_la_SOURCES): Add hash.c.
8207 * m4/symtab.c: More or less rewritten from scratch, within the
8208 bounds of the previous API.
8209 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
8210 call. Updated all callers.
8211 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
8212 declarations to reflect API changes.
8213 (M4INIT): Generate a declaration too, to avoid the warning with
8214 --enable-debug builds.
8215 (M4FINISH): Ditto.
8216 (HASHMAX): Removed.
8217 * m4/utility.c (hash_table_size): Removed.
8218 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
8219 names, which are then looked up by builtin_dumpdef() as necessary.
8220 This implies a small speedup in builtin_symbols(), which discarded
8221 all of the symbol info under the old call.
8222 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
8223 shadowing is implicit in respect to the new data structures.
8224 symbol names are no longer duplicated here, they are stored in the
8225 key field of the hash table.
8226 Moved macro_args and blind_no_args...
8227 (m4_token_data): ...to here.
8228 m4/macro.c (expand_macro): Added a name argument since the symbol
8229 name is no longer copied into each struct m4_symbol. Modified all
8230 callers.
8231 (collect_arguments): Ditto.
8232 * modules/m4.c (set_trace): Ditto.
8233 * modules/gnu.c (builtin_symbols): Updated.
8234 * src/freeze.c (produce_symbol_dump): Much improved in light of
8235 the improved symbol table layout.
8237 2001-09-01 Gary V. Vaughan <gary@gnu.org>
8239 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
8240 to M4_SYMBOL_NEXT.
8241 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
8242 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
8243 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
8244 SYMBOL_HANDLE): Ditto.
8245 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
8246 modules/gnu.c, modules/m4.c, src/freeze.c,
8247 src/main.c: Updated all references.
8249 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
8250 Automake 1.5 chokes on dynamic source file lists, Besides, it is
8251 already listed in m4_LDADD... how did that ever used to work?
8252 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
8253 link.
8254 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
8255 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
8257 * tests/m4: Don't call the m4 wrapper script with libtool, it
8258 works fine all by itself.
8260 2001-08-30 Gary V. Vaughan <gary@gnu.org>
8262 The experimental `changeword' feature never took off, and has
8263 no obvious advantages over `changesyntax' to compensate the
8264 enormous speed penalty it carries:
8265 * configure.in (ENABLE_CHANGEWORD): Removed.
8266 * m4/m4module.h (m4_set_word_regexp): Removed.
8267 * m4/m4private.h (m4_token_data): Removed original_text field.
8268 * m4/utility.c (m4_token_data_orig_text): Removed.
8269 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
8270 * m4/macro.c: Ditto.
8271 * src/main.c: Ditto.
8272 * modules/Makefile.am (changeword.la): Removed.
8273 * modules/changeword.c: File removed.
8274 * doc/m4.texinfo: References to changeword and --word-regexp
8275 removed.
8276 * po/POTFILES.in: modules/changeword.c removed.
8277 * tests/atlocal.in (ENABLE_CHANGEWORD): Removed.
8278 * tests/builtins.at (changeword): Test removed.
8280 2001-08-30 Akim Demaille <akim@epita.fr>
8282 * bootstrap.sh: Create aclocal.m4 instead of modifying it.
8283 This also help having a single list of m4 files: in
8284 config/Makefile.am.
8285 * config/Makefile.am (STANDARD_MACROS): Rename as...
8286 (ACLOCAL_MACROS): this.
8287 (list-standard-macros): Remove.
8288 (spy): New.
8290 2001-08-29 Gary V. Vaughan <gary@gnu.org>
8292 In an attempt to moderate my egomania...
8293 * tests/modules.at: Remove attributions.
8295 * tests/generate.awk: When making substitutions to "@&t@", either
8296 "&" or "\&" in the substitution string argument to gsub refer back
8297 to the matched text. "@\\&t@" seems to work though, Tests 43 and
8298 67 now pass for me.
8300 2001-08-29 Akim Demaille <akim@epita.fr>
8302 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)
8303 (include, indir, multiquotes, patsubst, pushdef/popdef, regexp)
8304 (sync-lines, trace, translit, undivert, wrap): Move to...
8305 * tests/builtins.at: this new file.
8306 * tests/others.at (Discard comments, import-environment): Move to...
8307 * tests/options.at: this new file.
8309 2001-08-29 Akim Demaille <akim@epita.fr>
8311 * tests/others.at (Freezing modules)
8312 (--module-directory: absolute path, modpath2, modpath3)
8313 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
8314 * tests/modules.at: here, new file.
8315 * tests/others.at, tests/generate.awk: Add a banner.
8316 * tests/testsuite.at: Adjust.
8317 (AT_CHECK_M4_FILTER): New, but unused.
8319 2001-08-29 Akim Demaille <akim@epita.fr>
8321 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
8322 handle that.
8323 * tests/others.at (wrap): Inline wrap.m4.
8324 (shadow): Inline shadow.m4.
8325 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
8326 * tests/m4: Simplify.
8328 2001-08-29 Akim Demaille <akim@epita.fr>
8330 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
8331 --language.
8333 2001-08-29 Akim Demaille <akim@epita.fr>
8335 * tests/generate.awk (normalize): s/@__@/@&t@/.
8337 2001-08-28 Akim Demaille <akim@epita.fr>
8339 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.
8341 2001-08-28 Gary V. Vaughan <gary@gnu.org>
8343 * bootstrap (generate.awk): Generate test cases with new script.
8345 2001-08-27 Akim Demaille <akim@epita.fr>
8347 * tests/Makefile.am (installcheck-local): Don't use
8348 `dc_install_base' which is not visible here, but `exec_prefix'
8349 which is clearly the RT anyway.
8350 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
8351 related to testing a now installed m4.
8352 * tests/m4: Do it here.
8354 2001-08-27 Akim Demaille <akim@epita.fr>
8356 * tests/others.at (indir): Formatting change.
8358 2001-08-27 Akim Demaille <akim@epita.fr>
8360 * tests/Makefile.am (installcheck-local): New.
8361 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
8362 the test suite.
8363 Prefer options over envvars.
8364 * src/main.c (main): First bug caught by the test suite (yeah!):
8365 --batch lacked a `break' which resulted in an accidental
8366 invocation of --discard-comments.
8368 2001-08-27 Akim Demaille <akim@epita.fr>
8370 * tests/others.at (capitalize, changeword, comments, ddivert)
8371 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
8372 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
8373 (sysv-args, trace, translit, undivert): Don't rely on files in
8374 examples/: AT_DATA them.
8376 2001-08-27 Akim Demaille <akim@epita.fr>
8378 Let the test suite use a wrapper around the not installed m4 to
8379 pretend it is (installed).
8381 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
8382 such a way that m4 does not process them.
8383 * configure.in: The package name seems to be `m4', not `M4'.
8384 * tests/m4: New.
8385 * tests/atlocal.in (at_package, M4): Remove.
8386 * tests/testsuite.at, tests/others.at: Use m4, not $M4.

8392 * examples/mktests.sh: Remove.
8394 2001-08-27 Akim Demaille <akim@epita.fr>
8396 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
8397 Don't use aclocal: it's written by hand.
8398 * aclocal.m4: m4_include all the files instead of being built by
8399 aclocal.
8400 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
8401 until it reads the traces by itself.
8402 * configure.in: Require Autoconf 2.42c as we are now using
8403 AC_CONFIG_TESTDIR instead of AT_CONFIG.
8404 Catch unexpanded `jm_' macros.
8405 * config/atconfig.m4: Remove.
8406 * config/error.m4: new.
8407 * config/Makefile.am: Ship the files included by aclocal.m4.
8408 * tests/Makefile.am (TESTSUITE_SOURCES): Rename as...
8409 (TESTSUITE_AT): this, to please Automake.
8410 (TESTSUITE): This target uses autotest/autotest.m4, not
8411 autotest/general.m4.

8418 2001-08-20 Gary V. Vaughan <gary@gnu.org>
8420 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
8421 Robert Collins, building on Cygwin no longer requires Windows
8422 import and export symbol decorations.
8423 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.
8424 * m4/error.h (M4_SCOPE) [cygwin*]: Ditto.

8435 * modules/Makefile.am (AM_CPPFLAGS) [cygwin*]: Ditto.
8437 2001-08-20 Gary V. Vaughan <gary@gnu.org>
8439 Ansify the source. Previously we had a mix, where my code was
8440 in a K&R compatible style, and the preexisting code was in ANSI
8441 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
8442 and now the code base is much cleaner.
8444 * m4/system.h: Remove M4_PARAMS macro and all users. Remove
8445 VOID macro and all users.
8446 * m4/m4module.h: Ansify function prototypes and headers.
8447 * m4/builtin.c: Ditto.
8448 * m4/evalparse.c: Ditto.

8462 * src/main.c: Ditto.
8464 2001-08-20 Akim Demaille <akim@epita.fr>
8466 * config/atconfig.m4: s/EOF/ATEOF/, so that configure can be
8467 generated with stock 2.52.

8471 * config/atconfig.m4: New, until part of Autoconf per se.

8475 * tests/atlocal.in: New.
8476 * tests/generate.awk: For the time being, the empty quadrigraph is
8477 `@__@'.
8478 * tests/others.at (changeword, gmp): Check the configuration
8479 variable against `yes'.
8480 * tests/testsuite.at (dnl): Allow it, as it's used all over the
8481 place.
8483 2001-08-20 Akim Demaille <akim@epita.fr>
8485 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
8486 * modules/m4.c (undivert): Disable the possibility of undiverting
8487 several files at once: it is not documented, it is inconsistent
8488 with the other macros, it can be straightforwardly mocked by
8489 several invocations, and most importantly, it prevents the
8490 possibility of other kinds of extension.
8491 Use `m4_numeric_arg'.
8493 2001-08-20 Akim Demaille <akim@epita.fr>
8495 * examples/include.m4: Typo.
8496 * tests/generate.awk: Really add it.
8497 * tests/Makefile.am: Adjust.
8498 * tests/others.at (Discard comments): It sure fails without `-c'.
8499 (include, undivert): Add -I examples/.
8501 2001-08-20 Akim Demaille <akim@epita.fr>
8503 Use sprintf, not ecft and friends since it is standard, portable,
8504 simplifies the code, and since the latter is even deprecated
8505 according to the GNU libc documentation.
8507 * modules/format.c: Drop evct support.
8509 2001-08-19 Gary V. Vaughan <gary@gnu.org>
8511 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Cleaned up. Don't test
8512 for `-pipe' here...
8513 * configure.in: ...do it here instead.
8515 * c-boxes.el: Deleted.
8516 * m4/builtin.c: Reformat box comments to be closer to GNU
8517 standards.

8545 2001-08-17 Akim Demaille <akim@epita.fr>
8547 * tests/others.at (iso8859): Specify the path to the M4 test file.
8548 * tests/testsuite.at (AT_CHECK_M4): Normalize the path of input
8549 files in error messages.
8551 2001-08-17 Akim Demaille <akim@epita.fr>

8554 * tests/others.at: Adjust input files paths.

8561 * tests/Makefile.am (EXTRA_DIST): Ship generate.awk.
8562 (generate.at): Install a temporary hack until the actual
8563 generate.awk is added to the repository.
8564 * tests/atconfig.in: New.
8566 2001-08-17 Akim Demaille <akim@epita.fr>
8568 Really apply the patch ``Drop Autoconf 2.13 compatibility.''
8570 2001-08-17 Akim Demaille <akim@epita.fr>
8572 * doc/m4.texinfo: Promote proper quotation.

8611 2001-08-17 Akim Demaille <akim@epita.fr>
8613 others.at no longer depends on other-tests/.
8615 * tests/others.at (stackovf): You're actually...
8616 (sync-lines): this.
8617 (modfreeze, modpath1, modpath2, modpath3, modpath4, modtest, shadow)
8618 (unload.test): Keep their authorship.
8619 (discard-comments, gmp, import-environment, modfreeze)

8632 (AT_CHECK_M4): Don't overquote. Blush...
8634 2001-08-17 Akim Demaille <akim@epita.fr>

8639 * examples/reverse.m4, tests/other-tests/import-environment.m4,
8640 * tests/other-tests/iso8859.m4: Don't produce trailing blanks.

8644 * tests/other-tests/modpath2.test, tests/other-tests/modpath3.test,
8645 * tests/other-tests/modpath4.test, tests/other-tests/modtest.test,
8646 * tests/other-tests/patsubst.test, tests/other-tests/reverse.test,

8648 * tests/testsuite.at, tests/others.at: New.
8649 * tests/Makefile.am: Adjust.
8651 2001-08-17 Akim Demaille <akim@epita.fr>
8653 Drop Autoconf 2.13 compatibility.
8655 * configure.in (changeword): No need to undefine it, as anyway if
8656 it's defined, M4sugar moved it as m4_changeword.
8657 And anyway, proper quotation is enough.
8658 (m4_pattern_allow): As it exists in 2.50, just use it.
8659 (AC_OUTPUT): Split in AC_CONFIG_FILES and AC_CONFIG_COMMANDS.
8660 Don't handle Gettext's duties, let it handle them.

8670 --error-output.
8671 * doc/Makefile.am: Add `TAGS' support.
8672 (MAINTAINERCLEANFILES): Remove texinfo.tex and mdate-sh which are
8673 in `config/' now.
8674 * config/Makefile.am (MAINTAINERCLEANFILES): New.
8676 2001-08-17 Akim Demaille <akim@epita.fr>

8693 2001-08-16 Gary V. Vaughan <gary@gnu.org>

8697 * acinclude.m4: Regenerated.
8698 * m4/ltdl.c: Updated from master copy.
8699 * m4/module.c: Reimplemented to take advantage of advances in

8708 (m4_modules): No longer required.
8709 (m4_module_init_t, m4_module_finish_t): POSIX namespace
8710 violations, renamed to...
8711 (m4_module_init_func, m4_module_finish_func): ...these,
8712 respectively.
8713 (M4INIT_HANDLER): Clean way to declare init functions in modules.
8714 (M4FINISH_HANDLER): And similarly for finish functions.
8715 * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER
8716 -- Add indirection to the CONC macro so that arguments are
8717 correctly expanded.
8718 * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
8719 * modules/shadow.c (m4_init_module): Ditto.
8720 Due to new init function semantics, be careful to perform the
8721 initialisation only on first load.
8722 * modules/perl.c (m4_init_module): Ditto. And Ditto.
8723 (m4_finish_module): Replaced with M4FINISH_HANDLER.
8724 Due to new finish function semantics, be careful to perform the
8725 finalisation only on first load.
8726 * m4/m4private.h (m4_module): Removed in favour of...
8727 (m4_module_data): ...structure without all the wrapper fields.
8728 Instances of this new structure are stored associated lt_dlhandles
8729 with lt_dlcaller_data_set().
8730 * m4/builtin.c (m4_builtin_define): Takes a handle argument
8731 instead of the old module argument.
8732 (m4_builtin_table_install): Ditto.
8733 * modules/load.c (m4_resident_module): Removed. This is no
8734 longer implemented as a magic symbol...
8735 * modules/m4.c (m4_resident_module): Ditto.
8736 * modules/load.c (M4INIT_HANDLER): ...the module init function now
8737 uses the ltdl api to make the module resident.
8738 * modules/m4.c (M4INIT_HANDLER): Ditto.
8739 * modules/load.c (builtin_modules): Traverse the loaded module
8740 list with lt_dlhandle_next.
8741 (builtin_load): Much simplified in light of the reimplemented
8742 module loader.
8743 * src/freeze.c (produce_module_dump): Cleaned up and optimised in
8744 light of the m4/module.c rewrite.

8749 (libm4_la_SOURCES): Delete list.c reference.
8750 * m4/m4private.h (m4_token_data): Add a handle field. This
8751 eliminates many of the searches to find the handle associated with
8752 various tokens that are passed between functions.
8753 (struct m4_symbol): Removed the module field. The
8754 module association does not belong with the symbol...
8755 * m4/input.c (struct m4_builtin): ...it belongs with the builtin
8756 that the module implementation code is from. Added a handle
8757 field.
8758 (m4_push_macro): Add a `handle' argument. Changed all callers.
8759 (init_macro_token): Set the `handle' field for the
8760 m4_token_data.
8761 * m4/macro.c (expand_argument): Copy the new handle field during
8762 reassignment.
8763 * modules/m4.c (macro_install): Use the new handle field to
8764 optimise the search for the correct builtin structure, and pass
8765 the handle details to m4_builtin_define.
8767 2001-08-15 Akim Demaille <akim@epita.fr>
8769 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Be sure `m4/' exists
8770 when creating `m4/obstack.h'.
8771 * tests/Makefile.am (TESTS_ENVIRONMENT): Pass top_srcdir and
8772 top_builddir.
8773 * tests/defs: Make them absolute.
8774 (CDPATH) Neutralize.
8775 * tests/gethem: Use them.
8777 2001-08-14 Gary V. Vaughan <gary@gnu.org>
8779 * config/ltmain.sh: Doh! Import again for a quoting fix that
8780 prevented any regression test from passing.
8782 * m4/m4module.h (obstack.h): Choose between installed version
8783 and shipped version based on configure tests.
8784 * src/freeze.c (obstack.h): Ditto.

8790 them to AC_INIT and AM_INIT_AUTOMAKE.
8791 * Makefile.am (AUTOMAKE_OPTIONS): Remove `gnits' which would
8792 disallow MY_NAME and MY_VERSION arguments to AM_INIT_AUTOMAKE.
8793 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Don't choke on
8794 shell variable m4_cv_func_obstack_h.
8795 * tests/defs (M4): Be more careful about relative path to libtool
8796 script and m4 binary by using $srcdir.
8798 * src/main.c (main): Use lt_dlinsertsearchdir to prepend -M
8799 optargs to the existing libltdl search path.
8800 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.
8801 * m4/ltdl.c: Updated.
8802 * m4/ltdl.h: Ditto.
8803 * config/ltmain.sh: Ditto.
8805 2001-08-11 Gary V. Vaughan <gary@gnu.org>
8807 * src/main.c (main): Add `-b' (for `batch') mode switch to force
8808 interactive mode off.
8810 2001-08-10 Akim Demaille <akim@epita.fr>
8812 * configure.in: Require Autoconf 2.52.
8813 (AC_ARG_PROGRAM): Remove, handled by Automake.
8814 (m4_getopt): Rename as...
8815 (m4_getopt_h): this.
8816 Allow the tokens `m4_cv_*', `m4_top_srcdir', and `m4_getopt_h'.
8817 Undefine `changeword' only if defined.
8818 * config/gnu-obstack.m4: Require Autoconf 2.52.
8819 (M4_AC_FUNC_OBSTACK): Rename `m4_obstack' and `m4_obstack_h'.
8820 Allow this token.
8822 2001-08-09 Yuji Minejima <ggb01164@nifty.ne.jp>
8824 * doc/m4.texinfo: Fix some typos, and apply some small
8825 clarifications.
8827 2001-08-09 Andreas Schwab <schwab@suse.de>
8829 * src/main.c (main): Fix improper uses of error (missing format
8830 string).

8834 Improve `make distcheck'.

8841 obstack.c.
8843 2001-08-07 Akim Demaille <akim@epita.fr>
8845 * m4/evalparse.c: A better introductory comment.
8846 * m4/m4module.h (M4_DEBUG_PRINT2): s/M4_debug/m4_debug/.

8863 * po/stamp-cat-id: Remove file.
8865 2001-04-08 Roderick Koehle <Roderick.Koehle@infineon.com>
8867 * modules/format.c (format): Formatting for %f was not
8868 interpreting the position of the decimal point correctly for
8869 whole numbers.
8871 2000-12-01 Gary V. Vaughan <gary@gnu.org>
8873 * TODO: Removed m4exit bug.
8874 * modules/load.c (m4_resident_module): Make this module resident.
8875 * module/m4.c (m4_resident_module): Ditto.
8876 * m4/modules.c (m4_module_load): Use new ltdl resident modules
8877 feature to mark modules as resident if they export
8878 `m4_resident_module' as TRUE.
8879 (m4_module_unload): Do not remove resident modules, and take care
8880 with symbol insertion and deletion with resident modules.
8881 * m4/ltdl.c, m4/ltdl.h: Update to latest unreleased versions to
8882 use resident modules feature.
8884 2000-11-30 Gary V. Vaughan <gary@gnu.org>
8886 * TODO: Updated. Removed some cruft that has since been fixed
8887 or implemented. Added some more entries.
8888 * NEWS: Updated.
8889 * README: Updated.
8890 * modules/README: Updated.
8891 * doc/m4.texinfo: Updated.
8893 * modules/gnu.c (builtin_functions): Make indir orthogonal to
8894 builtin, in that each is recognised as a macro only with parameters
8895 (builtin_indir): Passing 0 arguments is now an error, as with
8896 builtin.
8898 * src/main.c (usage): Added missing description of `-c' option.
8900 2000-11-29 Gary V. Vaughan <gary@gnu.org>
8902 Consolidate the myriad of dispersed test scripts into the
8903 tests subdirectory. I think I now have all the file where I
8904 want them, so there shouldn't be anymore upheaval =)O|
8905 Honest!
8906 * tests/Makefile.am: Updated to run the new tests added below.
8907 * tests/other-tests/capitalize.test, tests/other-tests/comments.test,

8924 of the tests removed below.
8925 * examples/Makefile.am, modules/Makefile.am: Updated to
8926 reflect removed tests.
8927 * examples/defs,modules/defs: Removed.

8943 modules/unfrozen.m4, modules/unload.test: Removed.
8945 Move the implementation of GMP support for the mpeval() builtin
8946 into a loadable module that depends on libgmp. mpeval() and
8947 eval() share a common parser, now in m4/evalparser.c; the code
8948 in m4/numb.c and m4/numb.h is now physically split between
8949 m4/eval.c (the eval() backend) and modules/mpeval.c (the
8950 mpeval() backend), rather than being differentiated by cpp
8951 macros and multiple inclusion. The mpeval module is always
8952 built but will generate an diagnostic if it is used from an
8953 installation that didn't link in the gmp library.
8954 * modules/Makefile.am: build and install the new mpeval module.
8955 * modules/mpeval.c: Now contains the former parts of m4/numb.c
8956 and m4/numb.h that are required for gmp support in mpeval().
8957 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
8958 * m4/evalmp.c: Removed.
8959 * m4/m4module.h: Removed conditional prototype for
8960 m4_mp_evaluate().
8961 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
8962 and m4/numb.h that do not rely on gmp.
8963 * m4/evalparse.c: New file, contains the shared parts of the
8964 eval() and evalmp() parser implementations, and is no longer
8965 unencumbered by cpp magic to uncover the right parts.
8966 * m4/numb.h: Removed. It's former contents are split between
8967 m4/eval.c and modules/mpeval.c.
8968 * m4/numb.c: ditto.
8970 * tests/other-tests/changeword.test: New test. Rudimentary
8971 testing of changeword builtin runs only if --wnable-changeword
8972 was used at configure time.
8973 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
8974 alternation correctly. Split into two expressions to compensate.
8975 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
8976 * modules/Makefile.am: Build changeword module.
8977 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
8978 only when --enable-changeword was passed to configure.
8979 (builtin_changeword): If --enable-changeword was not used, then
8980 report that changeword() builtin has no support in m4 binary.
8982 2000-11-28 Gary V. Vaughan <gary@gnu.org>
8984 * src/main.c (main): Fixed a particularly nasty bug is
8985 user_search_path setting -- the -M flag processing must be
8986 extremely careful with search path ordering, or else the default
8987 installed module directory (possibly containing modules from a
8988 previous release) is placed earlier in the search path than any -M
8989 arguments (which are relied upon to load uninstalled modules with
8990 most of the tests in the regresion suite).
8992 * modules/load.c (builtin_load): Nasty hack to prevent adding
8993 symbols to symtab again if a module is loaded more than once.
8994 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
8996 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
8997 possible NULL pointer dereference.
8999 * m4/module.c (m4_module_find_by_modname): Renamed from
9000 m4_module_modname_find. Fixed all references.
9001 (m4_module_find_by_builtin): New function.
9003 * modules/modfreeze.test: load the `load' module with each
9004 invocation.
9005 * src/freeze.c (produce_frozen_state): Simplified in light of
9006 module field in m4_symbol. Allow a third argument for text macros
9007 to name the originating module.
9008 (reload_frozen_state): ditto.
9009 * m4/m4module.h: Fixup prototypes.
9010 * m4/builtin.h (m4_builtin_define): Add a module argument so
9011 that symbols can be registered against the defining module.
9012 (m4_macro_define): ditto.
9013 * m4/m4private.h (m4_symbol): Make the module field const to save
9014 on casting in the rest of the code.
9015 (SYMBOL_MODULE): New macro.
9017 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
9018 symbol reference maintenance bugs when removing a symbol from the
9019 symtab.
9021 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
9023 2000-11-27 Gary V. Vaughan <gary@gnu.org>
9025 * configure.in (m4_cv_func_obstack): A better check for whether
9026 libc has an obstack implementation.
9027 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
9029 * configure.in (--with-modules): Changed semantics. This
9030 option is now used to list modules to be preopened.
9031 * src/m4.h: #include "ltdl.h" unconditionally.
9032 * src/main.c: Removed all dependencies on WITH_MODULES.
9033 * src/freeze.c: ditto.
9034 * modules/Makefile.am: ditto.
9035 * m4/m4.c (builtin_m4exit): ditto.
9036 * modules/modpath1.test: ditto.
9037 * modules/modpath2.test: ditto.
9038 * modules/modpath3.test: ditto.
9039 * modules/modpath4.test: ditto.
9040 * modules/modtest.test: ditto.
9041 * modules/shadow.test: ditto.
9042 * modules/unload.test: ditto.
9044 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
9045 comes up on demand in LTLIBOBJS now.
9046 * configure.in (getopt_long): Creating and relying on a link for
9047 getopt.h on hosts with no getopt_long() of thier own works
9048 correctly now. This is necessary so that callers of getopt_long()
9049 can simply `#include <getopt.h>': the naive way of doing this
9050 would end up using our own getopt.h and the installed
9051 getopt_long(), which is asking for trouble!
9052 (obstack_init): A similar argument applies to obstack.h and
9053 obstack_init().
9055 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
9056 On Solaris-2.5 (at least) the native dlopen implementation
9057 gets confused about m4.o when looking for module "m4". This
9058 version always looks for .la an .$lib_ext suffixed names first
9059 to work around the problem. Sigh.
9061 * po/POTFILES.in: Take account of these file movements.
9062 * src/Makefile.am (m4_SOURCES): removed eval.c.
9063 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
9064 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
9065 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
9066 * modules/m4.c (builtin_eval): Use m4_evaluate().
9067 * m4/eval.c: Moved here from src/eval.c to facilitate
9068 implementation of eval() builtin as part of the `m4' loadable
9069 module.
9070 (m4_evaluate): renamed from evaluate for namespace cleanliness.
9071 * m4/numb.c: Moved here from src/numb.c, since it is #included
9072 into eval.c at compile time.
9073 * m4/m4module.h (m4_evaluate): Added prototype.
9074 * src/m4.h (evaluate): Removed prototype.
9076 2000-11-25 Gary V. Vaughan <gary@gnu.org>
9078 * modules/perl.c (builtin_perleval): Use PL_na for
9079 compatibility with perl-5.6.
9081 * src/main.c (main): It is now safe to
9082 ``m4_module_install("m4")'', without tripping over the m4
9083 binary itself!
9084 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
9085 versions having fixed the insidious module search order bug.
9087 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
9088 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
9090 * configure.in: Figure out whether to use the installed
9091 getopt.h or the supplied one.
9092 * src/Makefile.am: ditto.
9094 * po/POTFILES.in: List files in their new positions.
9096 * config/ltmain.sh: This needs to be checked in to match the
9097 libtool macros copied to acinclude.m4 (until a released
9098 libtool copes with m4's needs).
9099 * bootstrap: Run gettextize.
9101 2000-11-24 Gary V. Vaughan <gary@gnu.org>
9103 * AUTHORS: Added my details.
9104 * TODO: updated.
9105 * NEWS: updated.

9142 * modules/gnu.c: New file implementing a new loadable module wuth
9143 definitions for all the gnu extension builtins.
9144 * modules/format.c: Moved here from src/format.c. Now included
9145 directly by gnu.c.
9147 * src/main.c (main): Load the traditional module if m4 was
9148 started in `no_gnu_extensions' mode.
9149 * modules/traditional.c: New file implementing the ``unix'' macro,
9150 required when m4 is executed in traditional mode, as a loadable
9151 module.
9153 * src/main.c: Renamed from m4.c to avoid confusion with
9154 modules/m4.c.

9157 definitions for all m4 builtins that are not gnu extensions.
9159 * m4/Makefile.am: Adjusted to take new files below into account.
9160 * m4/m4module.h: Prototypes for exported functions and types moved
9161 to this directory from the src directory.
9162 * m4/m4private.h: Moved here from src/m4private.h to facilitate
9163 the migration of all builtin implementations to loadable modules.
9164 * m4/macro.c: Moved this file here from the src directory,
9165 renaming all exported symbols to use the prefix ``m4_''.
9166 * m4/builtin.c: ditto.
9167 * m4/module.c: ditto.
9168 * m4/symtab.c: ditto.
9169 * m4/debug.c: ditto.
9170 * m4/input.c: ditto.

9172 * m4/path.c: ditto.
9173 * m4/ltdl.h, m4/ltdl.c: ditto.
9174 * m4/utility.c: Odd functions moved here from files in the src
9175 directory to facilitate builtin migration.
9177 2000-08-12 Gary V. Vaughan <gary@gnu.org>
9179 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
9180 error message, to make translators' jobs a little easier.
9181 (builtin_builtin): ditto.
9182 (builtin_traceon): ditto.
9183 (builtin_traceoff): ditto.
9184 Reported by Akim Demaille <akim@epita.fr>

9206 (AC_OUTPUT): touch stamp-h.in, not stamp-h.
9208 * doc/m4.texinfo: Fixed to work with --html option of makeinfo.
9209 Removed `Prev', `Next' and `Up' fields of all @nodes now that
9210 makeinfo calculates them for us, and to make any future
9211 reorganisation easier.
9212 (Frozen files): Document format version 2.
9213 `V' now takes argument `2'.
9214 `F' can take a single argument if symbol and builtin names
9215 are the same, or 3 arguments if the builtin is from a module.
9216 New `S' specification for saving syntax table contents.
9217 New `M' specification for saving loaded module names.
9218 * src/freeze.c: Implement them.
9219 * src/input.c (syntax_code): For interpreting frozen syntax
9220 state.
9222 * examples/Makefile.am: Add the contents of the WWW directory to
9223 the distribution.
9224 * examples/WWW/Makefile: ditto,
9225 (%.htm): Compares file contents (not just sizes) to determine
9226 whether a change has occured.
9227 * examples/WWW/_header.htm: Bumped version number.
9228 * examples/WWW: Regenerated content.
9230 * m4/Makefile.am (AUTOMAKE_OPTIONS): Support for non-ANSI
9231 compilers comes much easier without ansi2knr.
9232 * src/Makefile.am (AUTOMAKE_OPTIONS): ditto.
9234 * m4/list.c: New generic list container type.

9307 (token_type): Renamed to `m4_token_t' for the same reasons.
9308 (token_data_type): Renamed to `m4_token_data_t' for the same
9309 reasons.

9358 * src/builtin.c: Much improved macro definition style.
9359 * src/m4private.h: Internal structures for m4_builtin and

9431 src dir and immediately after libm4 is built for confidence that
9432 it doesn't rely on the src directory.
9433 (SUBDIRS): Moved doc dir to the end since helptoman.pl and
9434 makeinfo stop the build on cygwin (because they don't work).
9436 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
9438 * m4/m4private.h: ...is not a public header, so moved to src.
9439 Add `#include <config.h>', `#define _COMPILING_M4' and
9440 `#include "m4.h".
9441 * m4/Makefile.am (noinst_HEADERS): remove m4private.h.
9442 * src/Makefile.am (noinst_HEADERS): add m4private.h.

9465 m4/libm4.la.
9466 * m4/m4error.h: Renamed error.h, for installation to

9482 From Akim Demaille <akim@epita.fr>
9484 2000-01-17 Gary V. Vaughan <gary@gnu.org>
9486 * src/ltdl.c: Use access() to abort doomed module load attempts
9487 if module file does not exist.
9489 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
9490 getopt1.o will already be used if appropriate, so I moved getopt.c
9491 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
9493 * modules/modpath1.test: Use correct filename in header line.
9494 * modules/modpath2.test: ditto.
9495 * modules/modpath3.test: ditto.
9496 * modules/modpath4.test: ditto.
9498 Without these changes lt_dlopen("test") attempts to
9499 LoadLibrary("/bin/test") on Windows, which although harmless
9500 generates a spurious error message which spoils most of the tests:
9501 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
9502 (TESTS): s/test.test /modtest.test /
9503 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /

9506 * modules/modpath2.test: ditto.
9507 * modules/modpath4.test: ditto.
9508 * modules/modpath3.test: s/-m test /-m modtest /
9509 * modules/shadow.m4: use {un,}loadmodule(`modtest').
9511 2000-01-16 Gary V. Vaughan <gary@gnu.org>
9513 * src/ltdl.c (find_file): Updated to new version with fixed memory
9514 allocation bug in `next'.

9517 * modules/Makefile.am: Cleaned up and reordered.
9519 2000-01-16 René Seindal <rene@seindal.dk>
9521 * modules/Makefile.am (TESTS): New tests for the module system.
9523 * modules/*.test: New files.

9526 Treats -M and -m as the arguments -D -U and -t, ie deferred.
9528 * src/m4.h: Added declaration of module_init().
9530 * src/module.c (module_init): No longer static
9532 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
9533 Added to shut up automake about non standard libtool library
9534 names.
9536 * src/module.c: Disabled DEBUG by default.
9538 * modules/README: Changed example from unload.m4 to shadow.m4
9540 * modules/shadow.m4: Renamed from unload.m4
9542 * modules/Makefile.am (EXTRA_DIST): Removed unload.m4.
9544 * src/m4.c (main): Functionality for -m and -M were reversed.
9545 Fixed.
9547 2000-01-12 Gary V. Vaughan <gary@gnu.org>
9549 * doc/help2man.pl: updated to version 1.020.
9551 * lib/COPYING.LIB: updated to version 2.1.
9553 * lib/m4module.h: restructure the M4_SCOPE code to work when
9554 creating a dll which links with libm4.la and both DLL_EXPORT
9555 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
9556 both defined.
9558 2000-01-11 Gary V. Vaughan <gary@gnu.org>
9560 Merged the following changes from my tree:
9562 1999-06-15 Gary V. Vaughan <gary@gnu.org>
9564 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
9565 ported to compile shared libs.
9567 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
9568 use `__declspec(dllimport)' when linking libm4.la on win32.
9569 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
9571 * configure.in (M4OBJS): Discover whether we need the shipped
9572 implementation of getopt_long.
9573 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
9574 main binary here, as opposed to the module library in lib/libm4.la.
9576 1999-06-14 Gary V. Vaughan <gary@gnu.org>
9578 * modules/README: Updated to describe the improved libltdl based
9579 module scheme.
9580 * README (cygwin): Added some compilation notes for building m4
9581 correctly under cygwin.
9582 * TODO: Cleaned out the entries for the module system since they
9583 are now implemented.
9585 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
9586 all instances of __P with M4_PARAMS.
9588 * lib/getdate.h: removed unreferenced file.
9590 * lib/m4private.h: New file to define the private interface to the
9591 token_data struct, which must be shared between m4module.c, and
9592 builtin.c but not exported to modules built from the installed
9593 m4module.h since it's size changes depending on compile time
9594 options.
9596 * src/m4.h: Lots of stuff moved to lib/m4module.h.
9598 * lib/m4module.h: New file to define the interface available when
9599 compiling m4 modules.
9600 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
9601 necessary for module compilation into this new file.
9603 * lib/Makefile.am (include_HEADERS): install headers (renamed to
9604 avoid nameclash with other system headers) necessary for compiling
9605 modules.
9606 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
9607 so that modules can include the (renamed) installed headers and
9608 be guaranteed a matching implementation.
9609 * lib/m4error.h: renamed from error.h.
9610 * lib/m4obstack.h: renamed from obstack.h.
9611 * lib/m4regex.h: renamed from regex.h.
9612 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
9613 implementation, simply include the shipped version
9614 unconditionally, otherwise it is hard for a module to know
9615 whether the m4obstack.h header it is using matches the
9616 implementation it ends up linking against.
9617 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
9618 the same reason.
9620 1999-05-18 Gary V. Vaughan <gary@gnu.org>
9622 * examples/misc.test: Don't run this test on machines which don't
9623 have a root user in /etc/passwd (e.g. cygwin).
9625 * tests/get-them (/^@example$/): Error messages might have a
9626 ``.exe'' suffix to the program name, or else use the libtool
9627 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
9628 of these cases are now catered for when comparing error messages
9629 in generated tests.
9630 * tests/other-tests/*.test: ditto.
9631 * examples/*.test: ditto.
9633 * tests/defs (M4): use libtool execute mode.
9634 * examples/defs (M4): ditto.
9636 * tests/get-them (END): explicitly close any open file.
9637 (printthem): In a regular expression, '{' is the start of a repeat
9638 count! Use `[{]' for a literal open brace.
9639 (/^@node /): Don't use substr on a string shorter than the trim
9640 length.
9642 1999-05-17 Gary V. Vaughan <gary@gnu.org>
9644 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
9645 substituted.
9646 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
9648 2000-01-10 Andreas Schwab <schwab@suse.de>
9650 * tests/other-tests/gmp.test: Find config.sh in build directory.
9652 * configure.in: Find tests/mkconfig.sh in $srcdir.
9654 * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in
9655 <signal.h> (for SUS2 compliant systems).
9657 * src/stackovf.c: Check for HAVE_SIGINFO_T in addition to
9658 HAVE_SIGINFO_H.
9660 2000-01-10 René Seindal <rene@seindal.dk>
9662 * Prerelease 1.4o.
9664 * TODO, NEWS: Cleaned up and updated.
9666 * src/m4.c (main): New variable exit_status for exit status in
9667 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
9668 file cannot be read instead of EXIT_SUCCESS.
9670 * src/builtin.c (m4_indir): Changed error message to help
9671 translators (from Akim Demaille <demaille@inf.enst.fr>).
9673 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
9674 Cygnus.
9676 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
9677 from glic 2.1.2.
9679 * src/input.c (match_input): Reordering of code, to avoid multiple
9680 calls to push_string_init() from obstack_grow(), which can happen
9681 with some compilers (found and fixed by James Bonfield
9682 <jkb@mrc-lmb.cam.ac.uk>).
9684 * src/stackovf.c: Added prototypes for ultrix.
9685 (setup_stackovf_trap): Added __P to cast.
9686 (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>)
9688 2000-01-09 René Seindal <rene@seindal.dk>
9690 * doc/m4.texinfo (Changequote): Added comment about changing
9691 quotes when the old quote is a part of the new.
9693 * src/builtin.c (expand_ranges): Added break after trailing dash.
9694 This caused misbehavious on some systems (found and fixed by Akim
9695 Demaille <demaille@inf.enst.fr>).
9697 * AUTHORS: Thomas Tanner included
9699 * acconfig.h: Added entry for ss_sp (see below).
9701 * configure.in (use_stackovf): Added check for stack_t with member
9702 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert
9703 <eggert@twinsun.com>).
9705 * doc/m4.texinfo (Frozen files): Added a simpler example for
9706 generating frozen files from several input files.
9708 1999-11-14 Paul Eggert <eggert@twinsun.com>

9715 * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal.
9717 * src/module.c: reindented.
9718 (module_load): return if this is a repeated load of same module.
9719 (module_init): slight change of logic to avoid repeated
9720 initialisation debug messages.
9722 * Makefile.am (DIST_SUBDIRS): Added to ensure modules/ is included
9723 in the distribution.
9725 * modules/Makefile.am (test_la_LDFLAGS): set to -module to silence
9726 automake warnings about missing lib prefix.

9735 1999-11-09 Paul Eggert <eggert@twinsun.com>
9737 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
9738 and zero, as Solaris 7 cc does.
9739 (bcopy): Remove macro; no longer needed with new obstack.h.
9741 * src/output.c (freeze_diversions): Don't assume that a
9742 diversion size can fit in `int'. Check for diversion file
9743 size too large to be printed with `unsigned long'.
9745 * src/Makefile.am (CFLAGS): Omit -Wall.
9747 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.
9749 * src/debug.c (trace_format):

9780 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
9781 avoidance on exported symbols.

9809 * src/Makefile.am (MAINTAINERCLEANFILES): ditto.
9810 * tests/Makefile.am (MAINTAINERCLEANFILES): ditto.
9812 * acinclude.m4: removed. `aclocal -I acm4' handles this much
9813 better.
9814 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
9815 * acm4/gettext.m4: removed. It causes a multiple definition vs.
9816 the installed gettext.m4 file when running aclocal.
9818 1999-03-25 Gary V. Vaughan <gary@gnu.org>
9820 * configure.in (AM_INIT_AUTOMAKE): bumped version number to
9821 distinguish this from the last prerelease.
9822 (AC_LIBLTDL_CONVENIENCE): build libltdl as a convenience library
9823 in its own subdirectory.
9825 * modules/Makefile.am (*_SOURCES): renamed to use libtool's "no
9826 lib prefix on a module" feature.
9827 (LDFLAGS): Added `-module -avoid-version' flags to build
9828 versionless module libraries.
9829 * src/builtin.c (m4_load_module): use libltdl.
9830 (module_unload_all): use libltdl.
9831 * src/m4.c (module_init): initialise module loading on demand for
9832 better diagnostics, and so that m4 will still work even if
9833 the module code is broken.
9834 * src/m4.h (module_init): removed. No longer relevant.
9835 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on
9836 exported symbols for compatibility with dlpreopening.
9837 * modules/test.c (m4_macro_table, m4_init_module,
9838 m4_finish_module): ditto.
9839 * modules/time.c (m4_macro_table): ditto.
9841 * bootstrap: New file. Runs all the autoutils in the right order
9842 after a fresh checkout, or a make maintainer-clean.
9844 1999-02-18 Akim Demaille <demaille@inf.enst.fr>
9846 * src/builtin.c (dump_symbols): New function, factoring common
9847 content of m4_dumpdef and m4_symbols.
9848 (m4_dumpdef): Use it.
9849 (m4_symbols): New function, implementing `symbols'. Use it.
9850 * doc/m4.texinfo: Fixed missing commas after @xref, so that the
9851 file compile with modern makeinfo.
9852 (Symbols): New node, documenting symbols.
9853 (direntry): Modernize.
9855 1998-12-11 René Seindal <rene@seindal.dk>
9857 * src/builtin.c (predefined_tab): New predefined macros
9858 __m4_changeword__, __m4_gmp__ and __m4_modules__ for testing for
9859 configure time options.
9861 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
9863 * src/module.c (module_try_load): Don't try to be clever and
9864 overwrite argument string. Instead allocate all constructed
9865 strings locally, since they can have arbitrary lengths. Make
9866 arguments pointers to const.
9867 (module_search): Simplify due to above change.
9869 1998-11-29 René Seindal <rene@seindal.dk>
9871 * Prerelease 1.4n.
9873 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): New tests.

9882 New global variable discard_comments.
9884 * src/m4.h (token_type): New TOKEN_NONE for tokens to be
9885 discarded, ie never returned from next_token().
9886 Added declaration of discard_comments.
9888 * src/input.c (next_token): Now loops until token type is not
9889 TOKEN_NONE. Comments are now given this type when comments should
9890 be discarded.
9892 * doc/m4.texinfo (Invoking m4): Updated for --import-environment
9893 and mpeval.
9895 1998-11-28 René Seindal <rene@seindal.dk>
9897 * src/m4.c (main): New option --import-environment (no single
9898 letter option).
9900 * When configured with --with-gmp both the normal (fast) eval()
9901 and the gmp aware mpeval() are defined. To restore previous
9902 bahaviour use "define(`eval', defn(`mpeval'))".
9904 * tests/other-tests/gmp.m4: Changed to use mpeval().
9906 * src/evalmp.c: New file for compiling eval.c as gmp aware.
9907 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
9909 * src/eval.c: Now includes "numb.c" directly. Everything in this
9910 file must by static, except evaluate(), which is changed to
9911 mp_evaluate() if USE_GMP in force.
9913 * src/numb.c: Changed to be included by eval.c instead of being
9914 compiled separately. Everything is declared static.
9916 * src/numb.h: Removed declarations of functions, as numb.c is now
9917 included by eval.c.
9919 * src/builtin.c: Declaration of m4_mpeval() added.
9920 Inserted `mpeval' in builtin table.
9921 (do_eval): New function with common code for m4_eval and m4_mpeval.
9922 (m4_mpeval): New function for gmp version of eval.
9924 * src/m4.h: Declaration of mp_evaluate().
9926 * src/Makefile.am (m4_SOUCES): Includes mpeval.c.
9927 (EXTRA_m4_SOURCES): Now has numb.c and numb.h
9929 * src/m4.c (main): m4 --version also shows which options were used
9930 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
9932 1998-11-27 René Seindal <rene@seindal.dk>
9934 * Error messages now always print program name before input file
9935 name as specified by GNU coding standards. Reported by Akim
9936 Demaille <demaille@inf.enst.fr>.
9938 * doc/m4.texinfo (Include): Change due to changed error message
9939 format.
9940 (Eval): Do.
9942 * tests/get-them: Minor change to sed script due to changed error
9943 message format.
9945 * src/m4.c (print_program_name): New func used to print program
9946 name, input file and line number in error (). Used as an
9947 error_print_progname handler.
9948 (reference_error): Removed.
9949 (main): Assigns error_print_progname.
9951 * src/m4.h (M4ERROR): Removed reference_error ().
9953 1998-11-25 René Seindal <rene@seindal.dk>
9955 * Updated to libtool 1.2b.
9957 * src/builtin.c (install_builtin_table): Added braces to avoid
9958 warning of ambiguous 'else'.
9960 * src/module.c: Inserted search path code from path.c modified to
9961 use new interface.
9962 (module_init): Configured default path used only if M4MODPATH is
9963 not set.
9964 (module_try_load): Now reads libMODULE.la as generated by libtool
9965 for actual module name.
9966 (module_load): Gives better error messages on failure.
9968 * src/m4.h: Added declarations of structures and functions for
9969 generic search path handling.
9971 * src/path.c: Removed all module specific code and introduced new
9972 functions of more generic search path handling.
9974 1998-11-24 René Seindal <rene@seindal.dk>
9976 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
9977 included gettext, as <libintl.h> might not be found
9978 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
9980 1998-11-22 René Seindal <rene@seindal.dk>
9982 * src/output.c (insert_diversion): Fixed bug that might cause m4
9983 to read from standard output! Triggered by input
9984 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
9985 so now 'undivert(0)' does nothing.
9987 1998-11-18 René Seindal <rene@seindal.dk>
9989 * Prerelease 1.4m.
9991 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
9992 could be changed when compiling a illegal regexp, causing later
9993 use of the regexp to dump core.
9995 * src/module.c (module_load): Changed error message to conform to
9996 standards.
9998 * src/m4.c (usage): Added message about reporting bugs.
10000 * doc/m4.texinfo (Changeword): Corrected a wrong example.
10001 (Changeword): Added note about the type of regexps used.
10003 * ltconfig, ltmain.sh: New files from Libtool 1.2.
10005 * configure.in: Added calls to AM_ENABLE_SHARED, AM_DISABLE_STATIC
10006 and AM_PROG_LIBTOOL.
10008 * acm4/modules.m4 (AM_WITH_MODULES): Redone completely to work
10009 with libtool.
10011 * modules/Makefile.am: Changed completely to compile modules using
10012 libtool. The modules are compiled as shared libraries, and are
10013 renamed when installed.
10015 * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
10016 USE_SHL_LOAD to HAVE_SHL_LOAD
10018 * src/builtin.c (shipout_string): Now tests for a NULL string.
10020 * src/module.c: New level of indirection around non-portable
10021 functions to load shared objects. Intended to encapsulate the non
10022 portable parts better and to reduce the number of #ifdefs in the
10023 code.
10025 * Makefile.am (DIST_SUBDIRS): Instead of EXTRA_DIST for added
10026 directory modules/ to the distribution.
10028 1998-11-15 René Seindal <rene@seindal.dk>
10030 * Prerelease 1.4l.

10033 functions: getcwd, getlogin, getpid, getppid, getuid, getpwnam,
10034 getpwuid, hostname, rand, srand, getenv, setenv, unsetenv, uname.
10036 * src/builtin.c (shipout_string): New convenience function for
10037 builtins and modules.
10039 * src/module.c (module_load): Tentative support for
10040 shl_load/shl_findsym, but I cannot test it. Copied from MetaHTML.
10042 * Makefile.am (SUBDIRS): Directory modules added if configured.
10044 * modules/Makefile.am: Now correctly compiles and installs
10045 modules in pkglibexecdir.
10047 * src/m4.h: WITH_MODULES defined iff HAVE_DLOPEN or USE_SHL_LOAD.
10048 These two are now initialised by autoconf macros.
10050 * src/path.c (module_env_init): MODULE_PATH is always on the
10051 search path.
10053 * src/Makefile.am: Now generated pathconf.h which defined the
10054 default MODULE_PATH.
10056 * configure.in (pkglibexecdir): Added defintion of pkglibexecdir,
10057 where modules are installed.
10059 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
10060 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
10061 build and install automatically, and it is prepared for other
10062 interfacec than dlopen().
10064 * src/builtin.c (predefined_tab): Added __m4_version__ for the
10065 current version of GNU m4. It is a GNU extension.
10067 1998-11-14 René Seindal <rene@seindal.dk>
10069 * tests/Makefile.am (GENERATED_TESTS): Added new
10070 generated-tests/changesy.8.test
10072 * doc/m4.texinfo (Changesyntax): Documentation for escape
10073 syntax class.
10075 * src/macro.c (expand_token): Check for escaped macro call before

10078 * src/builtin.c (m4_changesyntax): Added `@' flag to define escape
10079 characters
10081 * src/input.c: New static variable use_macro_escape, which is TRUE
10082 iff some character has code SYNTAX_ESCAPE
10083 (input_init): Added initialisation of use_macro_escape.
10084 (check_use_macro_escape): New function to synchronise
10085 use_macro_escape with the syntax table.
10086 (set_quotes): Added call to check_use_macro_escape()
10087 (set_comment): Do.
10088 (set_syntax): Do.
10089 (next_token): Added new case for IS_ESCAPE.
10091 * src/m4.h (SYNTAX_ESCAPE): Defined as simple syntax category.
10093 1998-10-13 René Seindal <rene@seindal.dk>
10095 * Prerelease 1.4k.

10098 generated-tests.
10100 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): Added manually
10101 maintained tests in tests/other-tests. These currently tests for
10102 8-bit transparency, multiple precision arithmetic and sync-line
10103 output. Test for stackoverflow detection does not work.
10105 * examples/Makefile.am (TESTS): Added tests for all example files.
10107 * examples/mktests.sh: New file. Help program for creating test
10108 files.
10110 * tests/mkconfig.sh: New file to generate tests/config.m4 and
10111 tests/config.sh. This is for tests of configure selectable
10112 features. Picks up all set WITH_ and ENABLE_ veriables from

10115 * src/path.c (path_search): Added argument 'char **expanded_name'
10116 to return the expanded name.
10118 * src/m4.h: Added 2nd argument to declaration of path_search().
10120 * src/m4.c (main): Added 2nd argument to path_search().
10122 * src/freeze.c (reload_frozen_state): Do.
10124 * src/builtin.c (m4_undivert): Do.

10137 * AUTHORS, ChangeLog: Changed all dates to ISO 8601.
10139 * intl/: Updated to GNU gettext 0.10.35.
10141 * doc/m4.texinfo (Format): Documented that format is blind.
10143 * src/builtin.c (builtin_tab): Builtin format marked as blind.
10145 1998-10-07 René Seindal <rene@seindal.dk>
10147 * Prerelease 1.4j.
10149 * tests/Makefile.am (GENERATED_TESTS): Changed .m4 extension to
10150 .test, as the files are no longer just m4 input.
10152 * tests/get-them (FILE): Changed .m4 extension to .test.
10154 * src/m4.h (token_type): New token type TOKEN_SPACE introduced.
10155 Otherwise quoted strings with leading whitespace first in a macro
10156 argument would be eliminated.
10158 * src/macro.c (expand_token): Handles new token type TOKEN_SPACE.
10159 (expand_argument): Do.
10161 * src/input.c (next_token): SPACE and NUM/OTHER characters are only
10162 grouped together iff both quote and comment strings are single
10163 character. Otherwise they might include a comment/quote leader.
10164 (next_token): Returns new token type TOKEN_SPACE.
10166 * src/builtin.c (push_builtin_table): New function to push a
10167 builtin_table on the stack without installing its contents.
10168 (find_builtin_by_name): Added call to push_builtin_table() if
10169 reading frozen files. Otherwise the builtins named in the frozen
10170 files could not be found.
10171 (install_builtin_table): Changed to use push_builtin_table()
10173 1998-10-04 René Seindal <rene@seindal.dk>
10175 * po/pl.po: Polish translation added.
10177 * po/POTFILES.in: src/module.c added.
10179 1998-10-04 René Seindal <rene@seindal.dk>
10181 * Prerelease 1.4i.
10183 * configure.in (ALL_LINGUAS): Added Polish pl.po
10185 1998-10-03 René Seindal <rene@seindal.dk>
10187 * Many files: Incorporated changes to implement dynamic modules.
10188 Detailed comments in src/modules.c and modules/README
10190 * src/module.c: New file, implements the OS dependant parts of
10191 dynamic module loading.
10193 * src/Makefile.am (m4_SOURCES): Added module.c
10195 * src/builtin.h: New file, declares some functions from builtin.c
10196 that are of use for other modules (shipout_int, numeric_arg,
10197 skip_space, bad_argc), and the macros ARG() and DECLARE().
10199 * src/builtin.c (install_builtin_table): New function. Each
10200 module brings in a builtin_table, which is pushed on a stack.
10201 (struct builtin_table): New struct for list of builtin_tables.
10202 (m4_loadmodule): New function to implement builtin "loadmodule".
10203 (shipout_int): No longer static, to be used by modules.
10204 (numeric_arg): do.
10205 (skip_space): do.
10206 (bad_argc): do.
10207 (builtin_init): changed to call install_builtin_table()
10208 (find_builtin_by_name): Now searches all builtin_tables
10209 (find_builtin_by_addr): do.
10211 * src/path.c: Reorganised to allow for two search paths, one for
10212 include files and one for modules.
10214 * src/m4.h: Added declarations for new functions in module.c and
10215 in path.c.
10217 * src/m4.c (main): Added call to module_init().
10219 * modules: New directory with a few demo modules.
10221 * Makefile.am (EXTRA_DIST): Added modules/* since modules/ is not
10222 in SUBDIRS.
10224 * configure.in: Added modules/Makefile to AC_OUTPUT.
10226 * configure.in: Added code to implement --with-modules. Tests for
10227 <dlfcn.h> and -ldl.
10229 * acconfig.h: Added WITH_MODULES
10231 1998-10-02 René Seindal <rene@seindal.dk>
10233 * examples/Makefile.am (pkgdata_DATA): Removed special target for
10234 check and variables TESTS. These tests are now run from the
10235 tests/ directory.
10237 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
10238 directory. The files stay there but the tests are run from the
10239 tests/ directory.
10241 * tests/Makefile.am (EXTRA_DIST): Added run-test.
10243 * tests/run-test: New file. Run a test manually
10245 * tests/Makefile.am, tests/get_them: Moved automatically generated
10246 tests (from the manual) to sub directory tests/gentest/. The
10247 tests/ directory had gotten a bit messy.
10249 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10251 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\
10252 wrap}.test: Added a few testcases.
10254 1998-08-21 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10256 * Prerelease 1.4h.
10258 * lib/Makefile.am (noinst_HEADERS): regex.h added
10260 * configure.in (jm_WITH_REGEX, jm_PREREQ_ERROR):
10261 acm4/{error,regex}.m4 (from fileutils-3.16u.tar.gz).
10263 * acm4/Makefile.am: created providing rules to create
10264 $(top_srcdir)/acinclude.m4 to be used by aclocal.
10266 * tests/defs (LANGUAGE, LC_ALL, LANG): force them to be
10267 `C'. Reported by Ulrich Drepper.
10269 * Makefile.am (SUBDIRS): Removed checks directory
10270 * configure.in (AC_OUTPUT): Removed checks/Makefile
10272 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
10273 the space when m4.texinfo is edited and whitespace.el is active.
10274 (Defn,example): idem.
10276 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10278 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
10279 ../COPYING. ../Makefile is a file which is certainly present when
10280 test is executed in testSubDir. One can't be sure that the COPYING
10281 file is in .. or ../.. in all situations, the ../Makefile is
10282 always there.
10284 * doc/m4.texinfo (Include): adjusted expected test output
10285 according to new tests, i.e. the input will always come from the
10286 file `in' created by the test.
10288 * tests/Makefile.am: Added three lines at the top to get
10289 esyscmd.1.test working.
10291 * tests/get-them: modified to generate clearer tests who will need
10292 less maintenance when new test examples are created in
10293 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
10294 need the generic file `defs') shell scripts creating `in', `ok',
10295 `out' and when apropriate `okerr' and `err' in the directory
10296 `testSubDir' when executed. The compare of `ok' and `out'
10297 (and of `okerr' and `err') will be the exit status of the test.
10298 `out' must match `ok' (and `okerr' must match `err') for the test
10299 to be succesful.
10301 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
10302 the tests generated by tests/get-them getting it input normally
10303 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
10304 (dot) before the numeric part) is reserved for all other (hand
10305 written) tests. The `+' means one or more times.
10307 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10309 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
10310 supported short man page to refer to info documentation
10311 * helptoman.pl: added
10312 * configure.in: AC_PATH_PROG(PERL,perl)
10313 * Makefile.am (SUBDIRS): doc after src
10315 * libitized with libit 0.5 from
10316 ftp://ftp.iro.umontreal.ca/pub/contrib/pinard/maintenance/libit.
10318 * configure.in (AC_REPLACE_FUNCS): added xmalloc xstrdup
10319 * lib/Makefile.am (libm4_a_SOURCES): removed automakely supported
10320 replacement functions, (libm4_a_LIBADD): @LIBOBJS@
10321 * configure.in (AM_WITH_REGEX), acconfig.h (WITH_REGEX): added
10322 lib/rx.{c,h}: added
10323 * configure.in (AC_CHECK_FUNC): getopt_long
10325 * src/m4.c (usage): Report bugs to m4-bugs@gnu.org.
10327 * TODO: added entry about dependencies
10329 1998-08-10 René Seindal <rene@seindal.dk>
10331 * Prerelease 1.4f
10333 * doc/m4.texinfo (Changesyntax): Added documentation for the macro
10334 "changesyntax".
10336 * src/builtin.c (m4_changesyntax): Added builtin macro
10337 "changesyntax" to modify the syntax table.
10339 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax

10842 1994-07-17 François Pinard <pinard@iro.umontreal.ca>
10844 * configure.in: Check for sigaction and sigvec. Add a new delayed
10845 check for RLIMIT_STACK, combine in the checking for getrlimit.
10846 All those things are not universally available.
10847 * stackovf.c: Split setting up the trap handler and catching
10848 signals, for better taking care of various configure outcomes.
10849 * examples/stackovf.sh: Correct a typo.
10850 Reported by Eric Backus, Jim Avera and Jim Meyering.
10852 1994-07-16 François Pinard <pinard@iro.umontreal.ca>
10854 * ansi2knr.c: New version sent by its author, Peter Deutsch.
10856 1994-07-15 François Pinard <pinard@iro.umontreal.ca>
10858 * Makefile.in: Modify so parallel make will not try making
10859 lib/libm4.a twice simultaneously.
10860 Reported by Jim Meyering.
10862 1994-07-14 François Pinard <pinard@iro.umontreal.ca>
10864 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
10865 error message, for when no code possibility exists. Even if this
10866 line is completely #ifdef'ed out, it brings a syntax error.
10867 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
10869 * Makefile.in (install): Have install depend on all too, for lib
10870 to be remade as needed.
10872 * examples/stackovf.sh: Try ksh, bsh and bash for shells
10873 providing ulimit, instead of using only ksh.
10874 Reported by Jim Avera and Joseph E. Sacco.
10876 1994-07-12 François Pinard <pinard@iro.umontreal.ca>
10878 * Makefile.in (check): Have it depend on all instead of m4. In
10879 this way, a change in lib will be detected and processed.
10881 * builtin.c (numeric_arg): Use strtol and verify the conversion,
10882 instead of using sscanf which stops as soon as there is a
10883 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
10884 and divert(1xyzzy) were all accepted without any warning or error
10885 messages.
10886 * m4.h: Declare strtol as long if not including stdlib.h.
10887 * configure.in: Check for limits.h, and replace strtol if missing.
10888 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
10889 * lib/strtol.c: New file, from elsewhere.
10890 Reported by Andreas Schwab.
10892 1994-07-07 François Pinard <pinard@iro.umontreal.ca>
10894 * macro.c (expand_macro): Cast value to (boolean) prior to
10895 assigning it to traced.
10896 Reported by Tom McConnell.
10898 * Makefile.in (m4): Always make all in lib first.
10899 Reported by Jim Meyering.
10901 1994-07-06 Jim Avera <jima@netcom.com>
10903 * stackovf.c: Isolated OS-dependent sections; Improved portability,
10904 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
10905 handlers), and a default error message if the fault address is not
10906 available (when neither siginfo.h nor BSD sigcontext are supported).
10907 * configure.in: Changes for stackovf.h: Check for sigcontext,
10908 sigaction, sigstack, and define rlim_t as int if necessary.
10909 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
10910 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
10911 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
10913 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
10915 * configure.in: Use AC_SET_MAKE.
10916 * Makefile.in: Use @SET_MAKE@.
10917 Reported by Jim Meyering.
10919 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
10920 Reported by Ian Taylor.
10922 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
10924 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
10925 because siginfo.h is unrelated to standard headers, and siginfo.h
10926 is already checked for.
10927 Reported by Joseph E. Sacco.
10929 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
10930 PROTOTYPES.
10931 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
10932 AC_PROTOTYPES.
10934 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
10936 * builtin.c (substitute): Use \& to represent this part of the
10937 string which was matched by the whole regexp, instead of
10938 representing the whole string. Any usage of \0 issues a warning
10939 and acts like \&, it will disappear in some subsequent release.
10941 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
10943 * m4.c: Complete prototype for forwarded declaration of usage.
10945 * input.c (init_macro_token): Correct own reference in error
10946 message. Previous name get_macro_func was referred to instead.
10947 (next_char): Correct own reference in error message. Previous
10948 name advance_input was referred to instead.
10950 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
10951 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
10952 and_term, not_term, logical_not_term, cmp_term, shift_term,
10953 add_term, mult_term, exp_term, unary_term, simple_term): Add
10954 prototype to forwarded declarations. Declare parameter v1 as
10955 eval_t * instead of int *. Same for local variable v2 in dyadic
10956 functions. Same for result in exp_term.
10957 * builtin.c (m4_eval): Declare value as eval_t instead of int.
10958 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
10959 unsigned_eval_t instead of unsigned int. Change casts accordingly.
10960 (shipout_int): Cast first argument of ntoa to eval_t.
10961 Reported by Thorsten Ohl.
10963 * macro.c: Complete the prototypes of forwarded expand_macro and
10964 expand_token.
10965 Reported by Thorsten Ohl.
10967 * m4.h: Define voidstar as void * or char * depending on __STDC__.
10968 The Ultrix 3.1 compiler cannot do much with void pointers.
10970 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
10971 * m4.c (xfree): Replace void * by voidstar.
10972 Reported by Tom McConnell.
10974 * ansi2knr.1: New, from elsewhere.
10975 * Makefile.in (DISTFILES): Distribute ansi2knr.1
10977 * Makefile.in (stamp-h.in): Avoid running ./config.status if
10978 stamp-h does not exist yet. This avoids running it a second time
10979 just after the initial ./configure.
10980 Reported by David MacKenzie and Tom McConnell.
10982 * m4.h: Replace the enum debug_info declaration with a series of
10983 #define's. The Ultrix 3.1 compiler would otherwise need casting
10984 (int) to most references, when used in expressions.
10985 Reported by Tom McConnell.
10987 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
10989 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
10990 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
10991 calls the compiler. Previously, FP_PROTOTYPES was only calling
10992 the preprocessor; by not being subject to CFLAGS, this was
10993 discouraging those flags asking for ANSI compilation.
10994 * acconfig.h: Document HAVE_PROTOTYPES.
10995 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
10996 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
10997 Reported by Eric Backus.
10999 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
11000 from the environment. Default CFLAGS to -g if not set.
11001 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
11002 * lib/Makefile.in: Have CFLAGS substituted from configure.
11003 Reported by Eric Backus and Tom McConnell.
11005 * configure.in: m4_undefine changeword before using AC_ENABLE.
11007 * m4.h: Declare prototypes for error (for ANSI compilers only),
11008 prefix_all_builtins and reference_error.
11009 Reported by Tom McConnell.
11011 * input.c (set_word_regexp): Do not try to initialize the array
11012 test from a string, this does not work with non-ANSI compilers.
11013 Reported by Eric Backus.
11015 * Makefile.in (dist): Clean examples/ before saving it.
11016 (distclean-local): Also remove stamp-h.
11017 Reported by Eric Backus.
11019 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
11020 non ANSI compilers.
11021 Reported by Tom McConnell.
11023 * checks/Makefile.in (clean): Depends on mostlyclean.
11024 (mostlyclean): New goal.
11026 1994-06-24 François Pinard <pinard@iro.umontreal.ca>
11028 * Makefile.in (DISTFILES): Distribute install.sh.
11029 * install.sh: New file, copied from elsewhere.
11030 Reported by Assar Westerlund and Kaveh R. Ghazi.
11032 1994-06-23 François Pinard <pinard@iro.umontreal.ca>
11034 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
11035 * acconfig.h: Explain ENABLE_CHANGEWORD.
11037 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
11038 from code provided by Pete Chown]
11039 * m4.h: Add original_text field to u_t variant of union u.
11040 Declare TOKEN_DATA_FUNC macro.
11041 * builtin.c: Declare changeword.
11042 (m4_changeword): New function.
11043 * input.c: Include "regex.h", define variables with word regexps.
11044 (input_init): Initialize the word regexp.
11045 (set_word_regexp): New.
11046 (next_token): Declare local variables, use the previous code if
11047 default_word_regexp is true. Else, match using a new code. Save
11048 the original text.
11049 * macro.c (expand_token): Ship out original text if not a macro
11050 name.
11051 Reported by Krste Asanovic and Pete Chown.
11053 [These modifs all depend upon ENABLE_CHANGEWORD]
11054 * m4.h: Declare external user_word_regexp.
11055 * m4.c: Declare user_word_regexp, and initialize it from
11056 --word-regexp or -W, or NULL if not specified.
11057 * input.c: Use user_word_regexp if specified, instead of
11058 DEFAULT_WORD_REGEXP.
11060 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
11061 agree with it.
11063 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
11064 * checks/Makefile.in: Empty the suffix list.
11065 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
11067 * m4.c: Declare nesting_limit and initialize it to 250.
11068 Implement -LNUMBER or --nesting-limit=NUMBER to change its
11069 value.
11070 * m4.h: Declare nesting_limit as external.
11071 * macro.c (expand_macro): Stop execution whenever nesting limit
11072 is exceeded.
11073 Reported by Bengt Mertensson.
11075 * eval.c (evaluate): Diagnose excess characters in eval input.
11076 Things like `eval(08)' used to return 0 with no diagnostic.
11078 * m4.h: Capitalize first letter of all macro arguments in
11079 definitions.
11081 * m4.c: Declare warning_status, initialize it to 0. Add new
11082 option -E, or --fatal-warnings, which sets warning_status to
11083 EXIT_FAILURE instead.
11084 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
11085 EXIT_FAILURE if not otherwise done by header files.
11086 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
11087 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
11088 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
11089 argument of all M4ERROR calls.
11090 Reported by Noah Friedman.
11092 * examples/incl-test.m4: Renamed from incl_test.m4.
11093 * examples/include.m4: Include incl-test.m4 instead of
11094 incl_test.m4.
11095 * examples/multiquotes.m4: Renamed from multi-quotes.m.
11097 1994-06-22 François Pinard <pinard@iro.umontreal.ca>
11099 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
11100 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
11101 also tested it on a Sun Sparc workstation running SunOS 4.x.
11103 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
11104 49.format check, abusing a `union values' argument with sprintf
11105 without selecting the proper field. Now, save the formatting type
11106 first, delaying the fetch of the corresponding argument.
11107 Reported by Joseph E. Sacco and Tom Quinn.
11109 * format.c (format): Remove const from char *fmt declaration when
11110 not HAVE_EFGCVT, because a NUL may be forced into it.
11112 * m4.h: Declare atof() when not STDC_HEADERS.
11113 Reported by Joseph E. Sacco.
11115 * Regenerate configure using Autoconf 1.11, this corrects a
11116 problem about an incorrect cpp seting on NeXT 3.1.
11117 Reported by Alexander Lehmann.
11119 1994-06-05 François Pinard <pinard@iro.umontreal.ca>
11121 * m4.h (_): Change argument from `x' to `Args'.
11123 1994-04-22 François Pinard <pinard@iro.umontreal.ca>
11125 * m4.h: Rename Args() to _().
11126 * m4.h: Remove extern specifier from all function declarations.
11128 1994-04-22 Jim Avera <jima@netcom.com>
11130 * stackovf.c: New file implementing stack-overflow detection.
11131 * configure.in: Check for getrlimit, sigaction. If all of
11132 standard headers, getrlimit and sigaction, define USE_STACKOVF and
11133 substitute ${U}stackovf.o for STACKOVF.
11134 * acconfig.h: Declare USE_STACKOVF.
11135 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
11136 * m4.h: Declare setup_stackovf_trap().
11137 * m4.c: Call setup_stackovf_trap().
11138 * tests/stackovf_test.sh: New file.
11140 1994-04-13 François Pinard <pinard@iro.umontreal.ca>
11142 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
11144 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
11146 1994-01-30 François Pinard <pinard@iro.umontreal.ca>
11148 * m4.h: Remove definition of volatile, not used anymore.
11149 Reported by Jim Meyering and Joseph E. Sacco.
11151 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
11152 of `if ... else /* nothing */' for if macros.
11153 Reported by Jim Meyering.
11155 * builtin.c (m4_regexp): Reorganize the code for avoiding a
11156 warning from gcc about `repl' possibly used before defined.
11157 Reported by Jim Meyering.
11159 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
11160 Reported by Jim Meyering.
11162 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
11164 * m4.h: Move the conditional definition of volatile after the
11165 inclusion of system files, because they may define it first.
11167 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
11169 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
11170 get around a problem with Alpha make seeing a syntax error, there.
11171 Reported by Vern Paxson.
11173 1994-01-03 François Pinard <pinard@iro.umontreal.ca>
11175 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
11176 Reported by Richard Stallman.
11178 1993-12-25 François Pinard <pinard@iro.umontreal.ca>
11180 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
11181 instead of AC_HAVE_FUNCS.
11182 Reported by Noah Friedman.
11184 1993-12-01 François Pinard <pinard@iro.umontreal.ca>
11186 * m4.c: Initialize show_help and show_version to zero.
11188 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
11189 Use them in exit() and usage() calls.
11191 1993-11-27 François Pinard <pinard@iro.umontreal.ca>
11193 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
11194 syserr() macro. Delete errref, add reference_error and M4ERROR.
11195 * m4.c: Replace errref, which was returning an input reference
11196 string, with reference_error, which prints it on standard error.
11197 * builtin.c, output.c: Use errno as second parameter to error,
11198 instead of using syserr() with %s.
11199 * *.c: Use M4ERROR instead of error: no more errref() with %s.
11200 Doing so, the program name appears after the input reference
11201 instead of before, which eases M-x next-error processing.
11203 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
11205 * checks/get-them: Escape braces with backslashes in patterns,
11206 because HPUX-9.01 awk needs this.
11207 Reported by Jim Meyering.
11209 1993-11-22 François Pinard <pinard@iro.umontreal.ca>
11211 * builtin.c: Declare "FILE *popen ();".
11213 * m4.h: Remove MESSAGE{,1,2}, WARNING1, FATAL{,1}, INTERNAL_ERROR
11214 macros, replace error_message_prefix() declaration by errref()'s.
11215 Declare xrealloc, for use in errref().
11216 * m4.c: Delete error_message_prefix() function, add errref().
11217 * *.c: Use error() systematically in place of all error macros,
11218 now that error() flushes stdout first. Make needed adjustments.
11220 * m4.h: Remove const in sys_errlist[] declaration, it creates
11221 conflicts on SGI and Alpha.
11222 Reported by Kaveh R. Ghazi.
11224 1993-11-20 François Pinard <pinard@iro.umontreal.ca>
11226 * m4.c: Include <getopt.h> instead of "getopt.h".
11228 * configure.in: Output to config.h. Use HAVE_FUNCS preferably.
11229 * acconfig.h: New, for documenting HAVE_EFGCVT.
11230 * Makefile.in: Distribute acconfig.h, .stamp-h.in and config.h.in,
11231 use them wherever appropriate. Also use -I. for compilations.
11232 * lib/Makefile.in: Use -I.. for compilations.
11233 * *.c: Include <config.h> or "config.h".
11235 * m4.h: Test for HAVE_MEMORY_H instead of NEED_MEMORY_H.
11236 * configure.in: Use AC_HAVE_HEADERS(memory.h), delete AC_MEMORY_H.
11238 1993-11-17 François Pinard <pinard@iro.umontreal.ca>
11240 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
11242 * input.c (input_init): Initialize quote and comment strings
11243 explicitely instead of calling set_quotes and set_comment: by
11244 doing so, we ensure we do not free uninitialized variables.
11246 * checks/check-them: Reverse arguments to both diff, so the
11247 expected is on the left and the obtained on the right.
11249 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
11250 macros. Delete declarations for m4error, warning, fatal and
11251 internal_error, add declaration for error_message_prefix.
11252 * m4.c: Delete m4error, warning, fatal and internal_error
11253 routines, add error_message_prefix routine.
11254 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
11255 warning with WARNING*, fatal with FATAL* and internal_error with
11256 INTERNAL_ERROR*.
11257 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
11258 this is not needed anymore.
11260 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
11261 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
11262 and debug_message, add declaration for debug_message_prefix.
11263 * debug.c: Remove static specifier for FILE *debug declaration.
11264 Delete debug_print and debug_message routines, add
11265 debug_message_prefix routine.
11266 * builtin.c, debug.c: Replace debug_print routine calls with
11267 DEBUG_PRINT* macro calls.
11268 * input.c, path.c: Replace debug_message routine calls with
11269 DEBUG_MESSAGE* macro calls.
11271 * m4.h: Remove inclusion of <varargs.h>.
11272 * debug.c: Include <stdarg.h> or <varargs.h>.
11273 (trace_format): Use stdarg instead of varargs if __STDC__.
11275 * configure.in: Remove checks for vfprintf and _doprnt. These
11276 implementations use varargs tricks which are not portable enough.
11277 * lib/vfprintf.c: Deleted.
11278 * lib/_doprnt.c: Deleted.
11279 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.
11280 Reported by Joel Sherrill.
11282 * path.c (add_include_directory): Use xstrdup.
11284 * builtin.c (find_builtin_by_name): Declare static.
11286 * *.[ch]: Add const to a few "char *" declarations.
11288 * configure.in: Remove commented tests for fileno() and fstat().
11289 * debug.c: Remove comments about HAVE_FILENO and HAVE_FSTAT.
11291 * debug.c (debug_flush_files): New.
11292 * m4.h: Declares it.
11293 * builtin.c (m4_syscmd, m4_esyscmd): Use it.
11294 Reported by Nicolas Pioch.
11296 1993-11-12 François Pinard <pinard@iro.umontreal.ca>
11298 * Makefile.in (m4.dvi): Use m4.texinfo instead of m4.texi.
11299 Reported by Joel Sherrill.
11301 * builtin.c (prefix_all_builtins): Instead of the table size, use
11302 the null entry at end for stopping the loop. It was overwritten.
11303 Reported by Andreas Schwab and Jim Meyering.
11305 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
11306 Reported by Kaveh R. Ghazi.
11308 * macro.c (call_macro): Add * in (*SYMBOL_FUNC (sym)) (...).
11309 Reported by Karl Vogel.
11311 1993-11-09 François Pinard <pinard@iro.umontreal.ca>
11313 * m4.h: Do not define volatile if already defined.
11314 Reported by René Seindal.

11533 macro.c, output.c, path.c, symtab.c: Change Copyright from
11534 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
11536 * examples/divert.m4: Deleted, this bug has been corrected.

11540 * Makefile.in (clean): Remove clutter from ansi2knr.
11541 Reported by Pierre Gaumond.
11543 1992-12-20 François Pinard <pinard@iro.umontreal.ca>

11549 build directory.
11550 Reported by Jason Merrill.
11551 Reported by David MacKenzie.
11552 Reported by Skip Montanaro.
11553 Reported by Erez Zadok.
11554 Reported by Assar Westerlund.
11555 \f
11556 1992-12-19 François Pinard <pinard@iro.umontreal.ca>
11558 * Release 1.0.3
11559 This is still a beta release for the future GNU m4 version 1.1.
11561 * lib/alloca.c: New, from elsewhere.
11562 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
11564 * m4.h: Do not define index/rindex if already defined. If
11565 FALSE/TRUE are already defined, do not redefine them, but merely
11566 define boolean typedef to int.
11568 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
11569 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
11570 because some C compilers do not like connectives with #ifdef.
11571 * m4.h: Define `volatile' only if __GNUC__, instead of once for
11572 __GNUC__ and once for __STDC__.
11573 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
11575 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
11576 Makefile dependencies. Without it, make keeps destroying and
11577 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
11579 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
11580 to diversion/DIVERSION, this was a spelling error.
11582 * m4.c: Declare version[], remove #include "version.h".
11583 * version.h: Deleted.
11584 * Makefile.in: Remove references to version.h.
11586 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
11587 production, by using a simpler and more robust algorithm. This
11588 solves the problem of synclines sometimes written in the middle of
11589 an output line. Delete sync_line() and output_lines variable.
11590 * m4.h: Remove sync_line prototype and output_lines declaration.
11591 * input.c (next_char), output.c (shipout_text): Remove references
11592 to output_lines.
11593 * input.c (push_file, pop_file): Merely put the value -1 in
11594 output_current_line instead of calling sync_line, for delaying a
11595 single `#line NUM FILE' before next output line. Do not test
11596 for sync_output, because this is unnecessary clutter.
11597 * output.c (make_divertion, insert_divertion): Idem.
11598 * input.c: Rename must_advance_line to start_of_input_line, for
11599 consistency.
11601 * debug.c (trace_header): Select a new debug line format, which
11602 better complies with GNU standards for formatting error messages.
11603 With option `-dfl', M-x next-error might be used on the output.
11604 * m4.c (vmesg): Adjust format of error output to GNU standards.
11605 * m4.texinfo: Adjust examples for `make check' to work.
11607 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
11608 case for enum debug_info constants, which were all lower case.
11610 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
11611 re_search_2.
11612 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
11613 collected patches. I tried a few times using newer regex.[ch], it
11614 mysteriously stopped aborting with this one. Insecure feeling...
11615 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
11617 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
11619 * m4.c: Change `--no-warnings' to `--silent'.
11620 Reported by David MacKenzie.
11622 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
11623 leave it off for now. See comment in m4.c for justification.
11624 Reported by David MacKenzie.
11626 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
11627 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
11629 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
11631 * Makefile.in: Ensure recursive cleaning is done before local
11632 cleaning for all clean goals.
11634 * builtin.c (ntoa): Ensure the value is always interpreted as a
11635 signed quantity, whatever the radix is.
11637 1992-11-18 Jim Meyering <meyering@idefix>
11639 * builtin.c, format.c, input.c: Split long lines.
11640 * m4.c: Use typedef macro_definition instead of struct
11641 macro_definition.
11642 * symtab.c: Use typedef symbol instead of struct symbol.
11644 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
11646 * *.[ch]: Remove all trailing whitespace, in code and comments.
11648 * configure.in: Find some awk.
11649 * Makefile.in: Add $(AWK) to MDEFINES.
11650 * checks/Makefile.in: Transmit $(AWK) to get_them.
11651 * checks/get_them: Use $AWK instead of gawk. Add a close in the
11652 awk script when switching files, because without this, mawk runs
11653 out of file descriptors.
11655 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
11657 * Makefile.in (realclean): Delete m4.info*.
11658 Reported by Jim Meyering.
11660 * Makefile.in: Adjust and link with checks/Makefile.
11661 * checks/Makefile.in: New.
11662 * configure.in: Output checks/Makefile.
11664 * checks/get_them: Have the dnl header of each test more
11665 recognizable by next-error, also use a better message.
11667 1992-11-16 Jim Meyering <meyering@idefix>
11669 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
11670 And use that only if __GNUC__ since we're using it's GCC-specific
11671 semantics that tell the compiler the associated function doesn't
11672 return.
11674 * builtin.c (substitute): Don't use character as an array index.
11675 (dumpdef_cmp): Make formal arguments `const void *' to avoid
11676 warnings with gcc -W -Wall on systems with qsort prototype.
11677 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
11678 from gcc -W -Wall.
11680 * eval.c (most functions): Add parentheses to assignments used
11681 as truth values go avoid warnings from gcc -Wall.
11683 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
11684 any functions that don't need external scope.
11686 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
11687 (many functions and arrays): Declare `const'.
11689 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
11691 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
11692 removing the declaration from m4.h. Also rename false to FALSE
11693 and true to TRUE.
11695 * lib/Makefile.in (Makefile): New goal.
11697 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
11698 so heavily loaded. It gets more easily overridable, calling make.
11699 Reported by Jim Meyering.
11701 * Makefile.in (dist): Get .fname from the current directory name,
11702 instead of from version.h. I need updating many files manually,
11703 when the version changes, version.h is just one of them.
11705 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
11707 * m4.h: Remove the tag `boolean' on the enum introducing typedef
11708 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
11709 Reported by Tom McConnell.
11711 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
11713 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
11714 39.cleardiv, which were describing missing or spurious newlines.
11715 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
11716 do not depend on machine word size, `/bin/false' implementation,
11717 or `wc' output format. `make check' is more dependable, now.
11719 * checks/check_them: Summarize the failed tests by listing their
11720 name, at end. If none, issue `All checks successful'. Output
11721 `Checking' instead of `Input file:'.
11723 * checks/get_them, checks/check_them: Reindented.
11725 * Makefile.in (dist): chmod a+r before making the tar file.
11727 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
11729 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
11731 * input.c (next_token): Reinitialize token_buttom just after using
11732 it as a watermark with obstack_free. Or else, a future token, big
11733 enough for triggering reallocation of the obstack chunk, could
11734 void the initialized value of token_buttom, later causing panic in
11735 obstack_free. Rename token_buttom to token_bottom everywhere.
11737 * m4.h: Before declaring errno, first include <errno.h> and
11738 ensure that it does not define errno.
11739 Reported by Richard Stallman.
11741 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
11743 * builtin.c: Define and use DECLARE macro for builtins.
11745 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
11746 argument, this is a common idiom for introducing long comments.
11748 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
11749 arguments. The last argument was silently ignored.
11751 * m4.c (cmd_error): Add a missing semicolon before va_end().
11753 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
11755 * Makefile.in: Now handle protoized sources. Define and use U.
11756 Compile and use ansi2knr with old compilers. Update DISTFILES.
11757 Add `aclocal.m4' to `configure' dependencies.
11758 * ansi2knr.c: New, from Ghostscript distribution.
11759 * configure.in: Define U through FP_PROTOTYPES for old compilers.
11760 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
11761 * aclocal.m4: New, provide FP_PROTOTYPES.
11762 * m4.h: Conditionnaly protoized through Args, save for varags.
11763 * builtin.c: Protoized. Then:
11764 Include <sys/types.h> if size_t is not defined, before "regex.h".
11765 (m4_ifelse): Fetch built-in name properly for diagnostic.
11766 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
11767 (m4_regexp): Add const to `msg' declaration.
11768 (m4_patsubst): Add const to `msg' declaration.
11769 * debug.c: Protoized, save for varargs.
11770 * eval.c: Protoized.
11771 * format.c: Protoized.
11772 * input.c: Protoized.
11773 * m4.c: Protoized, save for varargs. Then:
11774 (xfree): Accept void * instead of char *.
11775 (xmalloc): Return void * instead of char *.
11776 (xrealloc): Accept and return void * instead of char *.
11777 * macro.c: Protoized.
11778 * output.c: Protoized.
11779 * path.c: Protoized. Then cast some (char *) over xmalloc's.
11780 * symtab.c: Protoized.
11782 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
11784 * m4.texinfo: Remove directory from diagnostics in 30.include,
11785 51.eval, 56.errprint and 57.m4exit tests.
11787 * m4.h: Remove declarations for int or void system functions, they
11788 cause more conflicting trouble than they make good.
11790 * configure.in: Avoid configuration header file. Add some tests.
11791 * m4.h: Remove #include "config.h".
11792 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
11793 Then, rewritten for better compliance with GNU standards.
11795 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
11797 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
11798 because of a misplaced #endif.
11800 * Many *.[hc] files: Correct intra-line spacing here and there,
11801 according to GNU indent 1.6 advice.
