1046 2008-05-08 Eric Blake <ebb9@byu.net>
1048 Stage 23: allow tracing of indirect macro calls.
1049 Track all trace information as part of the argv struct, rather
1050 than temporarily resetting global state. Teach indir to trace
1051 macros that it invokes.
1052 Memory impact: slight penalty, due to larger argv struct.
1053 Speed impact: none noticed.
1054 * m4/m4module.h (m4_input_block): Remove.
1055 (m4_call_info): New opaque type.

1100 Stage 22: allow builtin token concatenation outside $@.
1101 Adjust the input and argument parsing engines to append builtins
1102 alongside text. Make define warn when builtins must be
1103 flattened.

1208 * tests/null.out: Check for esyscmd failure.
1209 Reported by Elbert Pol.
1211 2008-04-14 Eric Blake <ebb9@byu.net>
1213 Stage 21b: $@ concatenates builtins, m4wrap takes builtins.
1214 Improve arg_print to handle builtin tokens when printing to a
1215 known chain, rather than always flattening builtins. This allows
1216 m4wrap and $@ back-references to handle embedded builtin tokens.
1217 Memory impact: none.
1218 Speed impact: slight penalty, from more bookkeeping.
1219 * m4/m4module.h (m4_push_builtin): Add parameter.
1220 (m4_builtin_print, m4_push_wrapup_init, m4_push_wrapup_finish)
1221 (m4_arg_print, m4_symbol_value_print): Rename and reduce scope...
1222 * m4/m4private.h (m4__builtin_print, m4__push_wrapup_init)
1223 (m4__push_wrapup_finish, m4__arg_print, m4__symbol_value_print):

1249 (Debuglen): Adjust expected output.
1251 Stage 21a: Optimize checks for end of input.
1252 Create a new polymorphic input block type, which always fails with
1253 CHAR_EOF, so that remaining input routines no longer have to check
1254 for NULL input block.
1255 Memory impact: none.
1256 Speed impact: noticeable improvement, from fewer conditionals.
1257 * m4/input.c (eof_funcs, input_eof): New objects.
1258 (eof_peek, eof_read, eof_unget): New functions.
1259 (file_clean, m4_push_string_init, pop_input, m4_push_wrapup_init)
1260 (m4_pop_wrapup, next_char, peek_char, unget_input, m4_input_init)
1261 (m4_input_exit): Use placeholder to guarantee non-NULL isp and
1262 wsp.

1264 easier manipulation. All callers changed.
1266 Improve OS/2 detection.
1267 * modules/gnu.c (m4_macro_table): Ensure all possible identifiers
1268 are defined, not just the first. The testsuite ensures that

1271 what other pre-defined macros it has.
1272 * THANKS: Update.

1309 to git.
1310 (AM_INIT_AUTOMAKE): Use version to decide gnu vs. gnits.
1311 * build-aux/mkstamp: Delete, no longer used.

1352 2008-03-17 Eric Blake <ebb9@byu.net>
1354 Stage 20a: reduce unget's in input engine.
1355 Now that out-of-range input placeholders like CHAR_BUILTIN are
1356 consumed outside of next_char, next_token should always consume
1357 rather than peek at the first character. Fewer peeks results in
1358 less ungetc overhead.
1359 Memory impact: none.
1360 Speed impact: noticeable improvement, from fewer function calls.
1361 * m4/input.c (struct input_funcs): Alter read_func prototype.

1417 * doc/m4.texinfo (Defn, Ifdef, Ifelse): Document and test the new
1418 behavior.
1419 (Debuglen): Likewise, and remove xfail.
1420 * NEWS: Mention the change.
1422 Stage 19b: invert sense of bit for handling builtin tokens.
1423 Pass builtin tokens by default, rather than as the exception, so
1424 that the logic can consistently refer to flattening arguments.
1425 Memory impact: none.
1426 Speed impact: none.
1427 * m4/m4module.h (M4BUILTIN_ENTRY): New convenience macro.
1428 (M4_BUILTIN_GROKS_MACRO): Rename...
1429 (M4_BUILTIN_FLATTEN_ARGS): ...and invert sense.
1430 (m4_symbol_value_groks_macro, m4_symbol_groks_macro): Likewise...
1431 (m4_symbol_value_flatten_args, m4_symbol_flatten_args): ...to

1434 (m4_symbol_value_groks_macro): Likewise...

1439 * m4/macro.c (collect_arguments): Accomodate changed sense.
1440 * m4/module.c (m4__module_open): Require arguments if flattening
1441 is requested.
1442 * m4/input.c (m4_push_string_finish): For now, flatten all
1443 builtins pushed as back-references.
1444 * modules/gnu.c (m4_builtin_table, builtin): Adjust all clients.
1445 * modules/import.c (m4_builtin_table): Likewise.

1453 * modules/m4.c (m4_builtin_table): Likewise.
1454 (mkstemp): Undo #undef hack from 2006-10-23, now that macro names
1455 are stringized without preprocessor expansion.
1456 * doc/m4.texinfo (Defn): Update comments to match reality.
1457 (Debuglen): Update test now that user macros pass builtin tokens.
1459 Stage 19a: sort and cache builtins loaded by a module.
1460 Rather than repeatedly using dlsym to browse the builtin table,
1461 copy off the table at module load time. Then, the input engine
1462 merely refers to the copy instead of duplicating information.
1463 Memory impact: slight penalty, due to more memory per module, but
1464 offset by less memory in input engine.
1465 Speed impact: slight improvement, due to faster builtin lookups.
1466 * m4/m4module.h (m4_set_symbol_value_builtin): Delete. Use
1467 m4_builtin_find_by_* instead.
1468 (m4_builtin_find_by_func): Change return type.
1469 * m4/m4private.h (m4__builtin): New struct.
1470 (m4_module): Add sorted list of loaded builtins.

1486 (m4_builtin_find_by_func): Change return type.
1487 * m4/input.c (struct m4_input_block): Simplify u_b, since most
1488 fields can be determined from builtin.
1489 (builtin_peek, builtin_read, builtin_unget, init_builtin_token)
1490 (m4__next_token): Alter parsing so that only init_builtin_token
1491 consumes a builtin.
1492 (builtin_print, m4_push_builtin): Adjust all users.
1493 * tests/macros.at (Arity, defn, and freeze): Fix typo.

1526 Import news from 1.4.10b.
1527 * NEWS: Update from branch.
1529 2008-02-23 Eric Blake <ebb9@byu.net>
1531 Stage 18: try harder to reuse argv in recursion.
1532 When pushing arguments that contain an existing $@ ref, reuse the
1533 ref rather than creating another layer of wrappers.
1534 Memory impact: noticeable improvement, due to better $@ reuse.
1535 Speed impact: noticeable improvement, due to O(n^2) to O(n)
1536 reduction in unboxed recursion.
1537 * m4/macro.c (make_argv_ref): Avoid wrapping $@ when possible.
1538 (m4_push_args): Let make_argv_ref take care of pending data.
1539 * doc/m4.texinfo (Improved foreach): Tweak wording to match new
1540 performance capability.
1541 * tests/others.at (recursion): Add tests to avoid performance
1542 regression.
1544 2008-02-22 Eric Blake <ebb9@byu.net>
1546 Update NEWS.
1547 * NEWS: Document change to __gnu__ on 2008-02-11.
1549 Stage 17: pass argv through quoted strings.
1550 Allow the concatenation of $@ references with other text input
1551 inside quoted contexts, which requires distinguishing between a
1552 wrapper around many arguments vs. a reference serving as part of a
1553 single argument. Also optimize based on whether argv contains
1554 builtin tokens that might need flattening to the empty string.
1555 Memory impact: noticeable improvement, due to O(n^2) to O(n)
1556 reduction from total reuse of $@ references.
1557 Speed impact: noticeable improvement, due to O(n^2) to O(n)
1558 reduction in boxed recursion.
1559 * m4/m4module.h (m4_arg_equal, m4_arg_len): Add parameter.
1560 (M4ARGLEN): Adjust definition.
1561 * m4/m4private.h (struct m4__symbol_chain): Add has_func member.
1562 (struct m4_symbol_value): Add wrapper and has_func members.
1563 (struct m4_macro_args): Add flatten and has_func members.
1564 * m4/input.c (append_quote_token): Return argv refs inside quoted
1565 strings.
1566 (init_argv_symbol): Populate new fields.
1567 * m4/macro.c (expand_argument, collect_arguments, make_argv_ref)
1568 (m4_make_argv_ref): Likewise.
1569 (arg_symbol, arg_mark, m4_is_arg_text, m4_is_arg_func): Use new
1570 fields.
1571 (m4_arg_equal, m4_arg_len): Handle quoted argv references, and add
1572 new parameter.
1573 * modules/m4.c (ifelse): Adjust caller.
1575 2008-02-22 Gary V. Vaughan <gary@gnu.org>
1577 Fix regression in argument collection, from 2008-01-21.
1578 * m4/input.c (m4__next_token): When DEBUG_INPUT is defined,
1579 undo argument collection optimisation for strings, so that
1580 m4_print_token doesn't abort when it otherwise receives an
1581 unprintable M4_SYMBOL_VOID type token.
1583 2008-02-20 Eric Blake <ebb9@byu.net>
1585 Stage 16: cache quotes and improve m4_arg_print.
1586 Cache rather than always copying quotes when pushing $@ refs; in
1587 particular, reconstruct single-byte quotes on the fly. Allow NUL
1588 through m4wrap. Improve sharing of code that prints arguments.
1589 Memory impact: slight improvement, due to cached quotes.
1590 Speed impact: slight improvement, due to less copying.
1591 * m4/m4module.h (m4_symbol_value_print, m4_symbol_print)
1592 (m4_arg_print): Adjust prototypes.
1593 (m4_dump_args): Delete.
1594 (m4_push_wrapup): Split...
1595 (m4_push_wrapup_init, m4_push_wrapup_finish): ...into these
1596 prototypes.
1597 * m4/m4private.h (struct m4_syntax_table): Add cached_quote
1598 member.
1599 (m4__quote_cache, m4__quote_uncache): New prototypes.
1600 * m4/syntax.c (m4_syntax_create): Initialize the cache.
1601 (m4__quote_cache): New function.
1602 (m4_set_syntax): Update caller.
1603 * m4/symtab.c (m4_symbol_value_print): Add parameter.
1604 (m4_symbol_print, dump_symbol_CB): Adjust all callers.
1605 * m4/utility.c (m4_dump_args): Delete; callers should use
1606 m4_arg_print instead.
1607 * m4/input.c (m4_push_wrapup_init, m4_push_wrapup_finish): Split
1608 implementation, and allow embedded NUL.
1609 (m4_print_token, pop_input, composite_print, composite_peek):
1610 (composite_read, append_quote_token): Adjust all callers.
1611 * m4/macro.c (trace_prepre, m4_arg_text, make_argv_ref):
1612 Likewise.
1613 (m4_arg_print): Add parameters.
1614 (trace_pre): Rewrite in terms of m4_arg_print.
1615 * modules/m4.c (errprint): Likewise.

1622 Fix out-of-bounds read for sanitized macro names, from 2008-02-06.
1623 * m4/utility.c (m4_verror_at_line): Properly terminate the string.
1624 Reported by Ralf Wildenhues.

1628 2008-02-19 Eric Blake <ebb9@byu.net>
1630 Clean up example on filtering defined symbols.
1631 * doc/m4.texinfo (Foreach, Improved foreach): Document another

1659 * doc/m4.texinfo (Improved forloop): Document advantage of $0.
1660 (Improved foreach): Adjust dump from file.
1662 Stage 15: return argv refs back to collect_arguments.
1663 Collect an entire $@ reference at once rather than one argument at
1664 a time, outside of quotes (but inside quotes, $@ is still
1665 flattened for now). The skip_last field allows concatenation of
1666 $@ with other text when collecting arguments.
1667 Memory impact: noticeable improvement, due to better reuse of $@.
1668 Speed impact: noticeable improvement, due to less parsing.
1669 * m4/m4private.h (CHAR_ARGV): New input engine sentinel.
1670 (enum m4__token_type): Add M4_TOKEN_ARGV.
1671 (struct m4__symbol_chain): Add skip_last member to argv link.
1672 (m4__next_token): Add parameter.
1673 * m4/input.c (peek_char, file_peek, builtin_peek, string_peek)
1674 (composite_peek, m4__next_token): Add new parameter.
1675 (composite_read, append_quote_token): Support argv in quotes.
1676 (init_argv_symbol): New function.
1677 (m4__push_symbol, match_input, consume_syntax)
1678 (m4__next_token_is_open, m4_print_token): Adjust callers.
1679 * m4/macro.c (m4_macro_expand_input, m4__arg_adjust_refcount)
1680 (arg_mark, m4_arg_text, make_argv_ref): Likewise.
1681 (expand_argument, collect_arguments): Handle new token.
1682 (arg_symbol): Drill through $@ reference.
1683 * m4/syntax.c (set_quote_age): Detect disabled comments.

1686 2008-02-15 Eric Blake <ebb9@byu.net>
1688 * modules/gnu.c (regexp_compile): Use a fastmap for regex speed.
1690 2008-02-13 Eric Blake <ebb9@byu.net>
1692 Fix texinfo grammar.
1693 * doc/m4.texinfo (Eval, Incompatibilities): Use @. after capital.
1694 (History): Use @: after abbreviations.
1695 (M4exit): Use correct Latin abbreviation.
1696 (Dumpdef, Debugmode, Frozen file format 2): Use correct spacing
1697 between sentences.
1699 2008-02-11 Eric Blake <ebb9@byu.net>
1701 Allow builtin text macros to specify number of arguments.
1702 * m4/m4module.h (struct m4_macro): Add argument limits to builtin
1703 text macros.

1767 * modules/perl.c (perleval): Likewise.
1769 Stage 14b: allow pushing argv references.
1770 Push a $@ reference to the input engine in one go, rather than
1771 pushing each element. For now, argument collection still gets one
1772 argument of a $@ at a time; but the penalties of this patch make
1773 it easier to manage $@ efficiently in future patches.
1774 Memory impact: noticeable penalty, due to larger struct and O(n)
1775 to O(n^2) on unboxed recursion.
1776 Speed impact: noticeable penalty, due to more bookkeeping.
1777 * m4/m4private.h (struct m4__symbol_chain): Add comma and quotes

1785 (expand_macro): Move argv cleanup...
1786 (m4__arg_adjust_refcount): ...to this new function.
1787 (m4_arg_symbol, m4_make_argv_ref, m4_push_arg): Factor...
1788 (arg_symbol, make_argv_ref, m4__push_arg_quote): ...to these new
1789 helper functions, to add parameters.
1790 (m4_push_args): Adjust caller.
1791 * m4/symtab.c (m4_symbol_value_print): Likewise.
1793 Stage 14a: allow printing argv references.
1794 Refactor symbol-value printing code for better sharing, and to
1795 allow printing a contiguous text representation of a $@ ref.
1796 Memory impact: none.
1797 Speed impact: none.
1798 * m4/m4module.h (m4_arg_print): New prototype.
1799 (m4_symbol_value_print): Alter prototype.
1800 * m4/input.c (struct input_funcs): Add parameter to peek_func.
1801 (file_peek, builtin_peek, string_peek): Ignore new parameter.
1802 (composite_peek): Ignore new parameter, for now.
1803 (composite_clean, pop_input): Rework to minimize indirection, and
1804 to avoid infinite recursion in next patch.
1805 * m4/macro.c (trace_prepre, trace_pre): Adjust callers.
1806 (m4_arg_print): New function.
1807 * m4/symtab.c (m4_symbol_value_print): Update signature.

1833 macros, used by libtool.
1834 (lib_LTLIBRARIES): Also used by libtool.
1835 (ltdl/libltdlc.la): Delete, now that libtool does this.
1836 * bootstrap: Mention new requirements.
1837 (LIBTOOLIZE): Provide default program, and run libtoolize prior to
1838 autoreconf.
1839 (autoreconf): Also neutralize libtoolize, since it is run early.
1840 * HACKING: Mention updated prerequisites.

1854 * bootstrap: Mention new dependency.
1855 * HACKING: Likewise.
1857 2008-01-27 Eric Blake <ebb9@byu.net>
1859 Stage 13: push composite text tokens.
1860 Support pushing composite tokens, allowing back-references to be
1861 reused through multiple macro expansions. Add hueristic that
1862 avoids creating new reference when pushing existing references.
1863 Memory impact: noticeable improvement due to better reference
1864 reuse, except for O(n) to O(n^2) copying in boxed recursion.
1865 Speed impact: slight penalty, due to more bookkeeping.
1866 * m4/m4private.h (m4__push_symbol): Adjust prototype.
1867 * m4/input.c (m4__push_symbol): Add parameter, and support

1920 Stage 12a: make m4_symbol_chain a union.
1921 Shrink size of symbol chains by using a union.
1922 Memory impact: slight improvement, due to smaller struct.
1923 Speed impact: slight improvement, due to less bookkeeping.
1924 * m4/m4private.h (enum m4__symbol_chain_type): New enum.
1925 (struct m4_symbol_chain): Rename...
1926 (struct m4__symbol_chain): ...to this, since it is internal.
1927 * m4/symtab.c (m4_symbol_value_copy, m4_symbol_value_print): All
1928 callers updated.
1929 * m4/input.c (struct m4_input_block, m4__push_symbol)
1930 (composite_peek, composite_read, composite_unget)
1931 (composite_clean, composite_print, m4__make_text_link)

1934 (m4_arg_equal, m4_arg_len, m4_make_argv_ref, m4_push_arg)
1935 (m4_push_args): Likewise.
1937 2008-01-23 Eric Blake <ebb9@byu.net>

1941 (LT_WITH_LTDL): Delete, now that it is obsolete.
1942 (LTDL_INIT): Use new libtool macro.
1944 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1945 and Eric Blake <ebb9@byu.net>

1949 distribution.
1950 * bootstrap: Update automake requirement.
1951 (func_version): Fix --version output, broken since 2007-08-06.
1952 * HACKING: Likewise. Add lzma requirement.
1953 * Makefile.am (clean-local-src): Not needed any more with newest
1954 Automake.
1955 (clean-local): Adjust.
1956 * TODO: Remove completed item.
1958 2008-01-22 Eric Blake <ebb9@byu.net>
1960 Doc tweak.
1961 * doc/m4.texinfo (Renamesyms): Avoid underfull hbox, and improve
1962 example.
1964 2008-01-21 Eric Blake <ebb9@byu.net>
1966 Stage 11: full circle for single argument references.
1967 Pass quoted strings through to argument collection in a single
1968 action, so that an argument can be reused throughout macro
1969 recursion if it remains unchanged.
1970 Memory impact: noticeable improvement, due to more reuse in
1971 argument collection stacks; O(n^2) to O(n) on boxed recursion.
1972 Speed impact: noticeable improvement, due to less copying.
1973 * m4/m4module.h (m4_arg_text): Add parameter.
1974 (M4ARG): Adjust.
1975 * m4/m4private.h (CHAR_QUOTE): New input engine sentinel.
1976 (m4__make_text_link): New prototype.
1977 (struct m4_symbol_chain): Add quote_age member.

1980 * m4/symtab.c (m4_symbol_value_print): Print composite tokens.
1981 (m4_symbol_value_copy, m4_symbol_value_delete): Recognize
1982 composite tokens.
1983 * m4/input.c (make_text_link): Rename...
1984 (m4__make_text_link): ...to this, and export.
1985 (m4_push_string_finish): Adjust caller.
1986 (make_text_link, m4__push_symbol): Update new field.
1987 (file_read, builtin_read, string_read, composite_read, next_char):
1988 Add parameter.
1989 (m4_skip_line, match_input, consume_syntax): Adjust callers.
1990 (append_quote_token): New function.
1991 (m4__next_token): Pass quoted strings onto argument collection.
1992 (m4_print_token) [DEBUG_INPUT]: Update.
1993 * m4/macro.c (expand_argument): Collect composite arguments.
1994 (collect_arguments): Update new field.
1995 (expand_macro): Reduce ref-count of back-references after use.
1996 (arg_mark, m4_arg_symbol, m4_make_argv_ref): Adjust to new member
1997 names.

2000 (m4_arg_equal): Compare composite symbols.
2001 (m4_push_arg, m4_push_args): Handle composite symbols.
2002 (m4_arg_symbol): Relax assertion.

2004 * m4/output.c (m4_shipout_string_trunc): Update comment.
2005 * tests/macros.at (Rescanning macros): Augment test.
2007 2008-01-16 Eric Blake <ebb9@byu.net>
2009 Stage 10: avoid extra copying of strings and comments.
2010 When collecting tokens that are immune to further expansion, avoid
2011 copying data from one obstack to another by outputting it into the
2012 destination obstack to begin with. Also reduce copying done in
2013 format builtin.
2014 Memory impact: slight improvement, due to better obstack usage.
2015 Speed impact: noticeable improvement, due less data copying.
2016 * ltdl/m4/gnulib-cache.m4: Import intprops and vasnprintf-posix
2017 modules.
2018 * m4/m4private.h (m4__token_type): Adjust prototype.
2019 * m4/input.c (m4__next_token): Support new parameter.
2020 * m4/macro.c (m4_macro_expand_input, expand_token)
2021 (expand_argument, collect_arguments): Adjust callers.
2022 * modules/m4.c (ntoa): Tighten buffer size.
2023 * m4/output.c (m4_tmpname): Guarantee no buffer overflow.
2024 * modules/format.c (arg_int, arg_long, arg_double): New helper
2025 functions, to detect overflow or unparsed characters.
2026 (ARG_INT, ARG_LONG, ARG_STR, ARG_DOUBLE): Adjust to check for
2027 missing or excess arguments.
2028 (format): Likewise, and also output directly into obstack if there
2029 is room.
2030 * doc/m4.texinfo (History): Update for new year.
2031 (Format): Test for new warnings.
2033 2008-01-15 Eric Blake <ebb9@byu.net>
2035 * TODO: Update with some newer URLs.
2037 Verify linear `index'.
2038 * tests/builtins.at (index): New test.
2039 (translit): Make test take longer, to make quadratic algorithms
2040 more apparent.
2042 2007-12-20 Eric Blake <ebb9@byu.net>
2044 Stage 9: share rather than copy single-arg refs.
2045 Use hooks of previous patch to create back-references to arguments
2046 in the input engine, and inline short text rather than always
2047 creating a FIFO link. Also start testing embedded NUL behavior.
2048 Until the argument collection engine also shares references, the
2049 memory usage increases.
2050 Memory impact: noticeable penalty, due to longer life of argv
2051 changing O(n) to O(n^2) on boxed recursion.
2052 Speed impact: slight improvement, due less data copying.
2053 * ltdl/m4/gnulib-cache.m4: Import memmem and quote modules.
2054 * m4/m4module.h (m4_arg_scratch): New prototype.
2055 * m4/m4private.h (m4__push_symbol): Add parameter.
2056 (m4_arg_scratch): Add fast accessor.
2057 (struct m4): Add expansion_level member, taken...
2058 * m4/macro.c (expansion_level): ...from here. Adjust all users.
2059 (expand_argument): Minor cleanup.
2060 (expand_macro): Track scratch space per macro call.
2061 (m4_arg_scratch): New function.
2062 (m4_make_argv_ref): Call new function.
2063 (m4_push_arg): Push reference to $0.
2064 (m4_push_args): Rework separator usage, since separators will
2065 usually be inlined.
2066 (process_macro): Allow embedded NUL.
2067 * m4/input.c (INPUT_INLINE_THRESHOLD): New define.
2068 (m4__push_symbol): Add parameter. Inline short strings, and save
2069 references through rescanning.
2070 * m4/symtab.c (m4_set_symbol_value_text): Weaken assertion.
2071 * modules/m4.c (errprint, index): Handle NUL transparently.
2072 (dumpdef, translit): Use scratch space, rather than expansion
2073 stack.
2074 * modules/gnu.c (renamesyms, m4symbols): Likewise.
2075 * tests/others.at (nul character): New test.
2076 (iso8859): Quote absolute file name, remove XFAIL.
2077 * tests/iso8859.m4: Avoid raw NUL in output.
2078 * tests/null.m4: New file.
2079 * tests/null.out: Likewise.
2080 * tests/null.err: Likewise.
2081 * Makefile.am (OTHER_FILES): Distribute new files.
2082 * .gitattributes: Treat new files as text.
2084 2007-12-17 Eric Blake <ebb9@byu.net>
2086 Stage 8: extend life of references into argv.
2087 Add hooks to lengthen the lifetime of arguments reused in a macro
2088 expansion, rather than always discarding arguments at the end of
2089 expand_macro. Rework the expand_macro obstacks to handle longer
2090 lifetimes. For now, the hooks remain unused.
2091 Memory impact: slight penalty, due to larger structs.
2092 Speed impact: slight penalty, due to more bookkeeping.
2093 * m4/system_.h (obstack_regrow): Delete.
2094 * m4/m4private.h (struct m4_symbol_chain): Add level field.
2095 (m4__push_symbol): Adjust prototype.
2096 (m4__adjust_refcount): New prototype.
2097 (DEBUG_MACRO) [DEBUG]: New debug control.
2098 (struct m4__macro_arg_stacks): New structure.
2099 (struct m4): Add arg_stacks, stacks_count fields.
2100 * m4/m4module.h (m4_make_argv_ref): Add parameter.
2101 * m4/macro.c (argc_stack, argv_stack): Delete, replaced by
2102 context->arg_stacks.
2103 (m4_macro_expand_input) [DEBUG_MACRO]: Add debug hooks,
2104 conditional on M4_DEBUG_MACRO envvar.
2105 (collect_arguments): Adjust signature.
2106 (expand_macro): Rework obstack handling.
2107 (m4__adjust_refcount, arg_mark): New functions.
2108 (m4_make_argv_ref): Populate new field.
2109 (m4_push_arg, m4_push_args): Track inuse.
2110 (process_macro): One less cast.
2111 * m4/m4.c (m4_delete): Clean up arg_stacks.
2112 * m4/input.c (make_text_link): Use new field.
2113 (m4__push_symbol, file_clean): Update signature.
2114 (composite_read): Bump refcount when done with reference.
2115 (composite_clean): New function.
2116 (pop_input): Adjust caller.
2117 * m4/debug.c (m4_debug_message): Make assertion match comment.
2118 * modules/gnu.c (builtin, indir): Adjust callers.
2119 * tests/builtins.at (ifelse): New test.
2120 (exp): Move and rename...
2121 * tests/others.at (countdown): ...to this.
2122 * doc/m4.texinfo (Improved foreach): Fix tracing usage in
2123 example.
2125 2007-12-13 Eric Blake <ebb9@byu.net>
2127 Yet more rewording.
2128 * doc/m4.texinfo (Inhibiting Invocation): Missed one instance in
2129 the previous patch.
2131 * THANKS: Update.
2133 2007-12-13 Paolo Bonzini <bonzini@gnu.org> (tiny change)
2135 * doc/m4.texinfo (Inhibiting Invocation): Fix quoting of a quoting
2136 example.
2137 Reported by Giovanni Toffetti.
2139 2007-12-11 Eric Blake <ebb9@byu.net>
2141 Stage 7: use chained input support in input parser.
2142 Allow the LIFO input engine to rescan a macro expansion composed
2143 of smaller chunks of FIFO data, rather than the old approach of a
2144 monolithic string. For now, all chunks are still copied.
2145 Memory impact: slight penalty, due to FIFO chain overhead.
2146 Speed impact: slight penalty, due to extra bookkeeping.
2147 * m4/m4private.h (m4__push_symbol): New prototype.
2148 (struct m4_symbol_chain): Add const-safety.
2149 * m4/symtab.c (m4_symbol_value_print): Simplify.
2150 (dump_symbol_CB): Update caller.
2151 * m4/input.c (struct m4_input_block): Alter u_c member, first
2152 introduced 2006-10-25, but unused until now.
2153 (composite_peek, composite_read, composite_unget)
2154 (composite_print, init_builtin_token): Rewrite accordingly.
2155 (m4_push_wrapup): No longer need trailing NUL.
2156 (m4__push_symbol, make_text_link): New functions.
2157 (m4_push_string_finish): Use them.
2158 * m4/macro.c (m4_push_arg, m4_push_args): Likewise.
2159 (expand_macro): Simplify logic of nesting_limit.
2160 * src/main.c (main): Likewise.
2161 * doc/m4.texinfo (Dumpdef): Augment test.
2163 2007-12-08 Eric Blake <ebb9@byu.net>
2165 Stage 6: convert builtins to push arg at a time.
2166 Add new methods to factor all builtins whose expansion includes an
2167 argument, making back-reference creation easier in future patches.
2168 Factor out length-limited printing to obstacks, and use -1 rather
2169 than 0 for unlimited length.
2170 Memory impact: none.
2171 Speed impact: slight improvement, due to better code sharing.
2172 * m4/m4module.h (m4_shipout_text): Rename...
2173 (m4_divert_text): ...to this, to avoid confusion with m4_shipout_*
2174 that does not worry about sync lines.
2175 (m4_shipout_string_trunc): New prototype.
2176 * m4/output.c (m4_shipout_text): Rename...
2177 (m4_divert_text): ...to this.
2178 (m4_shipout_string): Move guts...
2179 (m4_shipout_string_trunc): ...to this new function.
2180 * m4/macro.c (m4_push_arg, m4_push_args): New functions.
2181 (expand_token, process_macro): Update callers.
2182 * m4/input.c (string_print): Likewise.
2183 * modules/m4.c (ifdef, ifelse, shift, substr, translit, divert):
2184 Likewise.
2185 * modules/gnu.c (patsubst): Likewise.
2186 (debuglen): Use SIZE_MAX for unlimited debug length.
2187 * src/main.c (main): Likewise.
2188 * m4/m4.c (m4_create): Default max_debug_length to SIZE_MAX, not
2189 zero.
2191 2007-12-07 Eric Blake <ebb9@byu.net>
2193 Minor security fix: Quote output of mkstemp.
2194 * modules/m4.c (m4_make_temp): Produce quoted output.
2195 * doc/m4.texinfo (Mkstemp, Mkdtemp): Update the documentation and
2196 tests.
2198 Stage 5: add notion of quote age.
2199 Cache the quoting rules that were in effect when a string was
2200 parsed, to avoid reparsing that string if no changequote or other
2201 quote age change took place in the meantime. A quote_age of 0 is
2202 always safe, but does not benefit from caching.
2203 Memory impact: slight improvement, due to smaller struct in input
2204 engine.
2205 Speed impact: slight penalty, due to more bookkeeping.
2206 * m4/m4module.h (m4_get_symbol_value_quote_age): New prototype.
2207 (m4_set_symbol_value_text): Adjust prototype.
2208 (m4_has_syntax): Factor out the unsigned char cast.
2209 * m4/m4private.h (struct m4_syntax_table): Add syntax_age and
2210 quote_age members.

2214 member.
2215 (m4_set_symbol_value_text): Adjust fast accessor.
2216 (m4_get_symbol_value_quote_age): New fast accessor.
2217 * m4/symtab.c (m4_set_symbol_value_text): Add parameter.
2218 (m4_get_symbol_value_quote_age): New function.
2219 (m4_symbol_value_copy): Adjust callers.
2220 * m4/macro.c (expand_token): Add parameter, and track quote age.
2221 (expand_argument, collect_arguments): Track quote age.
2222 (m4_macro_expand_input, process_macro, m4_make_argv_ref)
2223 (m4_macro_expand_input): Update callers.
2224 (m4_arg_text, m4_arg_len, m4_arg_func): Abort on type mismatch.
2225 * m4/input.c: Comment cleanups.

2233 quote age.
2234 (set_quote_age): New helper function.
2235 (check_is_single_quotes, check_is_single_comments): Adjust
2236 callers.
2237 * src/freeze.c (reload_frozen_state): Likewise.
2238 * src/main.c (main): Likewise.
2239 * modules/m4.c (define, pushdef): No need to set macro text.
2240 * tests/builtins.at (changequote, defn): New tests.
2241 * examples/wrapfifo.m4: New file.
2242 * examples/wraplifo.m4: New file.
2243 * Makefile.am (dist_pkgdata_DATA): Distribute new examples.
2245 2007-12-04 Eric Blake <ebb9@byu.net>
2247 Fix builds with OpenBSD make.
2248 * Makefile.am (HELP2MAN): New macro.
2249 (dist_man_MANS, doc/m4.1): Fix rules for building m4.1 into
2250 srcdir.
2251 * README: Update copyright.
2252 * HACKING: Mention help2man and makeinfo dependencies.
2254 2007-11-29 Eric Blake <ebb9@byu.net>
2256 Stage 4: route indir, builtin through ref; make argv opaque.
2257 Finish making struct opaque to all but the input engine, by
2258 reworking obstack usage in expand_macro to better support creation
2259 of a $@ reference. Canonicalize the empty argument, to allow
2260 pointer comparison optimizations.
2261 Memory impact: slight penalty, due to larger struct.
2262 Speed impact: slight improvement, due to fewer function calls.
2263 * m4/system_.h (obstack_regrow): Fix precedence.
2264 * m4/m4module.h (m4_arg_equal, m4_arg_empty, m4_make_argv_ref):
2265 New prototypes.
2266 (struct m4_macro_args): Move...
2267 * m4/m4private.h (struct m4_macro_args): ...here, making it opaque
2268 to modules. Add has_ref member.
2269 (bool_bitfield): New helper typedef.
2270 (struct m4_symbol_chain): Add flatten and len members.
2271 * m4/macro.c (empty_symbol): New placeholder, for optimizing

2280 * modules/m4.c (ifelse, syscmd): Likewise.
2281 * modules/evalparse.c (m4_evaluate): Likewise.
2282 (undefine, popdef, m4_dump_symbols): Optimize.
2283 * modules/gnu.c (builtin, indir, esyscmd, debugfile): Use new
2284 methods.
2285 (changesyntax, regexp): Optimize.
2286 * m4/output.c (diversion_storage): Use typedef.
2288 Stage 3b: cache length, rather than computing it, in modules.
2289 Use cached token length in builtins and output engine.
2290 Memory impact: none.
2291 Speed impact: noticeable improvement, due to fewer function calls.
2292 * m4/hash.c (m4_hash_remove): Avoid double free on remove
2293 failure.
2294 * m4/output.c (m4_shipout_string): Change semantics of len param.
2295 (m4_shipout_int): Use cached length.
2296 * m4/input.c (m4_push_string_finish): Likewise.

2306 renamesyms, patsubst, regexp, regexp_compile): Likewise.
2307 * modules/load.c (m4modules): Likewise.

2317 * tests/others.at (iso8859): XFAIL this test, now that
2318 length-based handling allows NUL through part but not all of M4.
2320 2007-11-28 Eric Blake <ebb9@byu.net>
2322 Stage 3a: cache length, rather than computing it, in libm4.
2323 Cache the length of a token in the input engine and symbol table,
2324 to avoid repeating lots of strlen calls. Additionally, by using
2325 obstack length rather than strlen, the input engine can now
2326 support embedded NUL.
2327 Memory impact: slight penalty, due to larger struct.
2328 Speed impact: slight improvement, due to fewer function calls.
2329 * m4/m4module.h (struct m4_macro_args): Cache length.
2330 (m4_get_symbol_len, m4_get_symbol_value_len): New accessors.

2352 Adjust implementation.
2354 2007-11-27 Eric Blake <ebb9@byu.net>
2356 Stage 2: use accessors, not direct reference, into argv.
2357 Outside of macro.c, use accessor methods rather than direct access
2358 into the argv struct.
2359 Memory impact: none.
2360 Speed impact: slight penalty, due to increased function calls.
2361 * m4/m4private.h (m4_arg_argc): New fast accessor.
2362 * m4/m4module.h (m4_arg_argc, m4_arg_symbol, m4_is_arg_text)
2363 (m4_is_arg_func, m4_arg_text, m4_arg_len, m4_arg_func): New
2364 prototypes.
2365 (m4_builtin_func, M4BUILTIN, M4BUILTIN_HANDLER, m4_dump_args)
2366 (m4_macro_call): Make argc unsigned.
2367 (M4ARG): Use new accessors.
2368 * modules/m4.c (define, pushdef): Likewise.
2369 (undefine, popdef, ifelse, m4_dump_symbols, defn, undivert)

2381 usage.
2383 2007-11-24 Eric Blake <ebb9@byu.net>
2385 Stage 1: convert m4_symbol_value** into new object.
2386 Pass a variable-size wrapper structure instead of an array to
2387 builtins, so that subsequent optimizations in the structure need
2388 not impact every builtin client.
2389 Memory impact: slight penalty, since struct is larger than array.
2390 Speed impact: slight penalty, due to increased bookkeeping.
2391 * ltdl/m4/gnulib-cache.m4: Import flexmember module.
2392 * m4/m4module.h (m4_macro_args): New type, will be opaque to
2393 modules later.

2457 2007-11-14 Eric Blake <ebb9@byu.net>
2459 Handle some defn corner cases differently.
2460 * doc/m4.texinfo (Defn): Update documentation; although this still
2461 doesn't match the branch, since it may be changed before 2.0.
2462 * m4/macro.c (expand_argument): Consistently ignore builtins in
2463 concatenation contexts.
2464 * m4/m4private.h (m4__symbol_type): Fix C89 compliance bug.
2466 2007-11-13 Eric Blake <ebb9@byu.net>
2468 Note: Patches titled Stage 0 through N form a series of patches
2469 which decreases the algorithmic complexity of tail recursion in
2470 macro expansions from O(n^2) to O(n) in both time and memory, then
2471 performs cleanups, such as handling of embedded NUL, made easier
2472 by the code refactoring.
2474 Stage 0: Fix memory leak in tail recursion.
2475 Free expansion text in the input engine as soon as it is parsed,
2476 rather than when the recursive expansion completes.

2758 Work around a bug in darwin's awk:
2760 * bootstrap (func_get_translations): Use $AWK instead of raw
2761 `awk' so that the user can use an alternative implementation
2762 if the first awk in PATH doesn't behave as expected.

2764 entry passed to it for at least the awk implementation shipped

2768 2007-08-29 Gary V. Vaughan <gary@gnu.org>
2770 As gnulib xstrtol is only used by main, and unconditionally pulls

2782 * po/POTFILES.in: Track changes in files containing messages.
2783 * bootstrap (src_modules): getopt is now pulled into libgnu.a, no
2784 need to grab it separately.
2785 * src/main.c (OPT_STR, LONG_OPT_STR, short_opt_str, OPT_STR_INIT):
2786 No longer needed.
2787 (size_opt): Adjust to latest xstrtol interface.

3170 M4 was designed to have a small number of header files defining

5223 The regs_allocated field in a struct re_pattern_buffer refers
5224 to the state of a particular re_registers struct when used in
5225 successive matches using the same compiled pattern. Avoid a

5276 atlocal takes care of it instead.

5278 path to testsuite here, rather than relative path to testsuite
5279 elsewhere.

5335 const mpq_t is not assignable from plain mpq_t. Avoid
5336 type-punning warnings caused trying to mix these types.
5337 * modules/mpeval.c (numb_ior, numb_eor, numb_and, numb_lshift),
5338 (numb_rshift, numb_divide, numb_modulo): Remove const qualifier.

5363 ltdl.h is used.
5365 * bootstrap: Do not run libtoolize manually, this is done
5366 correctly by autoreconf. Invoke autoreconf with --no-recursive
5367 to avoid unnecessary rerunning of autotools for libltdl.
5369 2006-06-13 Eric Blake <ebb9@byu.net>
5371 * THANKS: Update.
5373 2006-06-12 Eric Blake <ebb9@byu.net>
5375 * m4/output.c [HAVE_MKTEMP]: Gnulib provides mkstemp, so don't

5406 * README-alpha: Update web address.
5407 * README: Likewise. Change encoding to ASCII. Remove old advice
5408 about cygwin. Document bootstrapping dependency.
5409 * AUTHORS: Update from branch-1_4.
5410 * THANKS: Likewise. Change encoding to UTF-8.
5411 * BACKLOG: Delete. This file is too old and unmaintained to be
5412 worthwhile.
5413 * ChangeLog: Change encoding to UTF-8.
5415 Avoid compiler warnings.
5416 * m4/macro.c (trace_format): Don't mark this as a printf format,
5417 since we don't accept the same set of modifiers as printf. It
5418 would be nice if gcc let us specify a custom format archetype.
5419 * src/main.c (main): Cast away const.
5421 2006-06-10 Andreas Schwab <schwab@suse.de> (tiny change)
5422 Eric Blake <ebb9@byu.net>
5424 * modules/time.c (ctime): Pass correctly typed variable to
5425 m4_numeric_arg.
5426 (gmtime): Likewise.
5427 (localtime): Likewise.
5428 (strftime): Likewise.
5429 * m4/utility.c (m4_numeric_arg): For now, document arbitrary
5430 limit inherent in this interface.
5432 2006-05-08 Bruno Haible <bruno@clisp.org> (tiny change)
5434 * modules/m4.c (WEXITSTATUS): Provide fallback definition.
5435 (sysval): Use WEXITSTATUS.
5436 * modules/gnu.c (esyscmd): Set sysval to 0xffff, to accomodate both
5437 big-endian and little-endian wait status definitions.
5439 2006-05-06 Eric Blake <ebb9@byu.net>
5441 * po/Makevars (MSGID_BUGS_ADDRESS): Add.
5442 * po/POTFILES.in (src/getopt.c, src/version-etc.c): These files live
5443 in src, not gnu.
5445 2006-05-06 Eric Blake <ebb9@byu.net>
5447 * configure.ac (LT_CONFIG_LTDL_DIR): Inform libtool which
5448 subdirectory to use.
5449 (support for -pipe): Move after LT_INIT, since it relies on
5450 libtool internals.
5452 2006-05-05 Eric Blake <ebb9@byu.net>
5454 * Makefile.am (doc/m4.1): Use $@, not $(srcdir)/doc/$@.
5456 * THANKS: Update.
5458 2006-05-05 Bruno Haible <bruno@clisp.org>
5459 and Eric Blake <ebb9@byu.net>
5461 * configure.ac (gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES): Move to...
5462 * ltdl/m4/gnulib-cache.m4: ...this new file, per new gnulib-tool
5463 usage pattern.
5464 * bootstrap: Update usage of gnulib-tool.
5466 2006-05-04 Eric Blake <ebb9@byu.net>
5468 * Makefile.am (doc/m4.1): Use EXEEXT on built binary.
5469 Cleanup whitespace.
5471 2005-12-05 Gary V. Vaughan <gary@gnu.org>
5473 * bootstrap (func_update_po): Synch with CVS GNU tar. wget 1.9.x
5474 and 1.10.x support --cache=off, so $WGETFLAGS are not necessary.
5475 Reported by Eric Blake <ebb9@byu.net>
5477 2005-12-04 Gary V. Vaughan <gary@gnu.org>
5479 * bootstrap (func_update_po): Test and set $WGETFLAGS to disable
5480 http caching as -C is no longer supported by wget 1.10.x.
5481 Reported by Eric Blake <ebb9@byu.net>
5483 2005-10-20 Gary V. Vaughan <gary@gnu.org>
5485 * m4/module.c (caller_id): To match libtool-2.0 interface, changed
5486 to ...
5487 (iface_id): ...an lt_dlinterface_id type.
5488 (m4__module_find): New abstraction for lt_dlhandle_fetch. Use
5489 throughout, instead of calling obsolete lt_dlhandle_find directly.
5490 (m4__module_next): Use multiloader-safe lt_dlhandle_iterate. Use
5491 throughout, instead of calling obsolete lt_dlhandle_next.
5492 * m4/m4private.h (m4__module_find): Declare it.
5493 * m4/builtin.c (m4_builtin_find_by_name, m4_builtin_find_by_func):
5494 Use m4__module_next instead of obsolete lt_dlhandle_next.
5496 2005-10-20 Gary V. Vaughan <gary@gnu.org>
5498 * bootstrap (func_update_po): Update pofiles directly from the
5499 translation project.
5500 * po/LINGUAS, po/cs.po, po/de.po, po/el.po, po/fr.po, po/it.po,
5501 po/ja.po, po/nl.po, po/pl.po, po/ru.po, po/sv.po: No need to store
5502 these files under source control anymore.
5503 Suggested by Eric Blake <ebb9@byu.net>
5505 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
5507 * ltdl/m4/m4-gnulib.m4: Update FSF contact address. Somehow this
5508 file escaped the address updates on 2005-05-01.
5510 2005-07-07 Gary V. Vaughan <gary@gnu.org>
5512 * bootstrap: Allow user overriding of gnulib-tool location, and
5513 correctly determine module source directories whether gnulib-tool
5514 is given as a relative or absolute path, or is found by searching
5515 PATH.
5516 Reported by Eric Blake <ebb9@byu.net>
5518 2005-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5520 * ltdl/m4/debug.m4 (m4_CHECK_DEBUGGING): Make sure that both $rm
5521 and $RM are defined for various versions of
5522 AC_LIBTOOL_COMPILER_OPTION.
5524 * bootstrap (AUTORECONF): New variable to allow user overriding of
5525 autoreconf path.
5527 2005-07-07 Gary V. Vaughan <gary@gnu.org>
5529 * doc/m4.texinfo (History): Add better notes on the ancestory of
5530 GNU m4, and other historical interest.
5532 2005-05-08 Gary V. Vaughan <gary@gnu.org>
5534 * m4/symtab.c (m4_symbol_rename): New function that performs a low
5535 level symbol rename.
5536 * m4/m4module.h (m4_symbol_rename): Declare it as part of the API.
5537 * modules/gnu.c (regsub): Factored out of m4_epatsubst_do...
5538 (m4_patsubst_do, m4_renamesyms_do): ...wrappers that use
5539 regsub...
5540 (erenamesyms, renamesyms): ...builtins that use these to implement
5541 macro renaming by regular expression.
5542 * doc/m4.texinfo (Erenamesyms and Renamesyms): Document them.
5543 * tests/generate.awk: Allow some forbidden `m4_' prefixed symbols
5544 to stop the new generated tests from choking.
5546 2005-05-07 Gary V. Vaughan <gary@gnu.org>
5548 Since most of the build is handled from a single Makefile.am now,
5549 we can teach make about the dependencies between the m4 binary and
5550 the preopened modules it is built against:
5552 * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
5553 preopened modules.
5554 * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
5555 of the preopened modules have changed.
5557 2005-05-07 Gary V. Vaughan <gary@gnu.org>
5559 * configure.ac (gl_MODULES): Add mkstemp for machines that don't
5560 have a native implementation.
5562 2005-05-06 Gary V. Vaughan <gary@gnu.org>
5564 * src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are
5565 handled already by gnu/exit.h.
5567 * configure.ac (gl_MODULES): Add assert to support a
5568 --disable-assert configure time option for NDEBUG setting.
5570 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.
5571 * bootstrap (src_modules): Add version-etc-fsf.
5572 * src/main.c (version_etc_copyright): Removed.
5574 * ltdl/m4/m4-getopt.m4 (m4_GETOPT): Synch with gnulib/getopt.m4.
5576 2005-05-04 Gary V. Vaughan <gary@gnu.org>
5578 * src/m4.h (__CYGWIN__, WIN32): Canonicalise Windows and Cygwin
5579 recognition macros.
5580 * src/freeze.c (produce_frozen_state): Use \n line-endings even
5581 on Windows, so that the frozen file reader will work.
5582 Reported by Josef T. Burger <bolo@bolo.com>
5584 2005-05-04 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
5586 Forward port of a patch that allowed m4-1.4.2 to compile on
5587 QNX 6.3:
5589 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
5590 sys/signal.h.
5591 * src/m4.h: And include them as appropriate.
5592 * src/main.c, src/stackovf.h: Don't include signal.h literally;
5593 m4.h will include the correct file.
5595 2005-05-04 Gary V. Vaughan <gary@gnu.org>
5597 * m4/m4private.h: Make errno visible for the sources patched
5598 below.
5600 2005-05-04 Paul Eggert <eggert@twinsun.com>
5602 * src/main.c (print_program_name_CB): Preserve errno, since
5603 M4ERROR relies on this.
5604 * modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
5605 * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
5606 * m4/path.c (m4_path_search): Don't let "free" trash errno when
5607 returning NULL.
5609 * m4/output.c (m4_insert_file): Don't assume errno has a valid
5610 value simply because fread returns zero. This fixes a
5611 portability bug reported by Marion Hakanson in
5612 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
5614 2005-05-04 Santiago Vila <sanvila@debian.org>
5616 * tests/stackovf.test: Use tempfile if available.
5618 2005-05-04 Robert Bihlmeyer <robbe@orcus.priv.at> (tiny change)
5620 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=92629
5621 * m4/output.c (m4_insert_file): Do not mix buffered and
5622 unbuffered I/O, as this breaks on the Hurd.
5624 2005-05-04 Gary V. Vaughan <gary@gnu.org>
5626 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
5627 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
5628 and libtoolize does a better job of ltdl importing now too, so
5629 take advantage of that while updating the tree:
5631 * acm4, config: Moved from here...
5632 * ltdl/m4, ltdl/config: ...to here.
5633 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
5634 src/Makefile.am, tests/Makefile.am: Removed...
5635 * Makefile.am: ...and migrated to here, with adjustments to
5636 compensate for relative path differences.
5637 * commit: Adjust relative paths.
5638 * configure.ac: Adjust relative paths.
5639 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
5640 patch.
5641 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
5642 the meanwhile, CVS HEAD libtool is needed.
5643 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
5644 stricly new enough, we also need a patch.
5645 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
5646 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
5647 (gl_MODULES): Don't list getopt and version-etc, as they don't
5648 belong in libm4.
5649 * bootstrap: After running gnulib-tool to import the listed
5650 modules, fetch getopt and version-etc into src manually.
5651 (ltdldir): Change to ltdl.
5652 * src/main.c: Adjust for changes in version-etc API.
5653 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
5654 but works when the getopt module isn't to be included in the lib.
5655 * README: Add note about patching autoconf and automake to
5656 bootstrap CVS m4.

5660 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=84416
5661 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
5662 empty file rather than to a nonexistent file. This closes a
5663 common security hole.
5664 * modules/m4.c (m4_maketemp): Implement the above, by using
5665 mkstemp rather than mktemp.
5667 2005-05-01 Gary V. Vaughan <gary@gnu.org>
5669 The FSF are moving offices today. Changed their contact address

5697 2004-12-24 Eric Blake <ebb9@byu.net>
5699 * configure.ac (INCLUDE_STDBOOL_H): Account for gnulib's move
5700 to the gnu subdirectory.
5701 * acm4/m4-error.m4 (INCLUDE_ERROR_H): Likewise.
5702 * acm4/m4-obstack.m4 (INCLUDE_OBSTACK_H): Likewise.
5703 * acm4/m4-regex.m4 (INCLUDE_REGEX_H): Likewise.
5704 * m4/system_.h: Likewise, in non-configured includes.
5706 2004-10-14 Noah Misch <noah@cs.caltech.edu>,
5707 Gary V. Vaughan <gary@gnu.org>
5709 * m4/m4.c (m4_context_field_table, m4_context_opt_bit_table):
5710 Protect definitions from macro expansion under -DNDEBUG by
5711 parenthesising the expanded function names.
5712 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
5713 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
5714 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
5715 (m4_is_syntax_macro_escaped): Similarly protect function
5716 definitions from macro expansion under -DNDEBUG by #undefing the
5717 matching macro names before each definition. Also, move all the
5718 function definitions to the end of the file so that any
5719 invocations in the rest of the file pick up the fast macro
5720 versions.
5721 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)
5722 (m4_set_debug_file, m4_set_trace_messages)
5723 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
5724 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
5725 (m4_set_max_debug_arg_length_opt): New fast macro versions of the
5726 option setter functions.
5728 2004-09-23 Gary V. Vaughan <gary@gnu.org>
5730 * po/POTFILES.in: Reflect move of gnulib files from gnulib/m4
5731 to gnu.
5733 2004-09-23 Gary V. Vaughan <gary@gnu.org>
5735 * src/main.c: Include gnulib files from the correct directory.
5737 * gnulib/*: Don't store any of the gnulib files in arch, as they
5738 generate spurious changes.
5739 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
5740 gnulib macros now share our macro directory.
5741 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
5742 * bootstrap: Call gnulib-tool to import from the gnulib tree.
5743 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
5744 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
5745 the gettext macros from autopoint that overwrite the gnulib-tool
5746 imported versions. Import sources and Makefile.am into the `gnu'
5747 directory. Changed all callers.
5748 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
5749 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
5750 for imported modules.
5751 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
5752 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
5753 hardcoding the gnulib macros they wrap.
5755 2004-07-15 Gary V. Vaughan <gary@gnu.org>
5757 Latest CVS libtool can preload modules in libraries, including
5758 its own module loaders! Tweak m4 so that it doesn't try to treat
5759 libltdl's module loaders as m4 modules when freezing and on exit:
5761 * gnulib/acm4/*.m4: Don't store these files in arch since they
5762 generate spurious changes.
5763 * bootstrap: Simplify initial libtoolize call, since CVS
5764 libtoolize is smarter these days.
5765 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
5766 build.
5767 * m4/module.h (m4__module_exit): Missing declaration.
5768 * m4/m4private.h (m4__module_next): New function declaration.
5769 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
5770 encapsulation. Changed all callers.
5771 (m4__module_interface): New function to verify m4 loadable module
5772 interfaces.
5773 (m4__module_init): Register the interface validator.
5774 (m4__module_exit): Only close my own modules.
5775 * modules/m4.c (unistd.h): Provide missing declaration.
5776 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
5777 (m4_expand_ranges): More missing declarations.
5778 * modules/modtest.c (export_test): Ditto.
5779 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
5780 * src/main.c (main): Bump copyright year.
5781 * tests/modules.at: Fix sed syntax error.
5784 2004-06-17 Gary V. Vaughan <gary@gnu.org>
5786 Tweaking to enable compilation with latest CVS libtool and
5787 libltdl. We can't just dump the library files directly into the
5788 m4 directory anymore now that libltdl is built from pieces itself:
5790 * bootstrap: Rewritten to use latest libtoolize sanely, and to
5791 set up libltdl subdirectory.
5792 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
5793 gnulib subdirectory's config.
5794 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
5795 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
5796 macros from gnulib.
5797 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
5798 configure.ac, so use AC_WITH_LTDL instead.
5799 * Makefile.am (SUBDIRS): Add libltdl.
5800 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
5801 gl_INCLUDED_REGEX.

5825 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
5826 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
5827 import.
5828 * gnulib/m4/getopt_int.h: New source file from latest gnulib
5829 import.
5830 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
5831 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,

5833 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
5834 Updated source files from latest gnulib.
5836 2004-02-29 Gary V. Vaughan <gary@gnu.org>

5846 number, and use it for the banner.
5847 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
5848 mhen the TIMESTAMP changes in ChangeLog, but the file modification
5849 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
5850 contain the previous version number.
5851 * src/main.c: Make --version output conform to the GNU standard.
5853 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
5854 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
5855 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
5856 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
5857 time_la_SOURCES): ...so that these are defaulted correctly, and
5858 can be removed from this file.
5859 (AM_LDFLAGS): Add -module...
5860 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
5861 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
5862 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
5863 the individual settings can be removed.
5864 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
5865 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
5866 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
5867 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
5868 time_la_LIBADD): ...so that these are picked up as a deplib of
5869 libm4 and don't need to be set explicitly.
5871 2003-11-18 Gary V. Vaughan <gary@gnu.org>
5873 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
5874 from the standard build. It is too fragile.
5876 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
5877 CVS libtool after merging m4 changes across to libtool.
5879 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
5880 * m4/path.c (search_path_add): Ditto.
5882 2003-11-13 Gary V. Vaughan <gary@gnu.org>
5884 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
5885 libtool tags we don't use in configure. This reduces the size
5886 of the script from over 1Mb to under 700Kb.
5888 2003-11-13 Gary V. Vaughan <gary@gnu.org>
5890 The import script was not written properly, and the last gnulib
5891 import was incomplete. Fixed that problem, and reimport our
5892 gnulib dependencies, which picks up the address calculation
5893 overflow checks described by Paul below. Also tweak the clients
5894 of the gnulib xalloc module not to use deprecated macros:
5896 * gnulib/import: Recurse through module dependencies rather than
5897 naively descending only one level.
5898 * configure.ac: Add calls to gnulib's strnlen and extension module
5899 macros.
5900 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
5901 extension modules.
5902 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
5903 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
5904 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
5905 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
5906 gnulib.
5907 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
5908 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
5909 place of `xcalloc (1, S)'.
5910 * m4/m4.c (m4_create): Likewise.
5911 * m4/m4private.h (m4_symbol_value_create): Likewise.
5912 * m4/symtab.c (symtab_fetch): Likewise.
5913 * m4/syntax.c (m4_syntax_create): Likewise.
5914 * src/freeze.c (reload_frozen_state): Likewise.
5915 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
5916 macro.
5917 * m4/symtab.c (m4_symtab_create): Likewise.
5919 2003-11-13 Gary V. Vaughan <gary@gnu.org>
5921 * tests/module.at: Comment typo.
5923 2003-10-10 Gary V. Vaughan <gary@gnu.org>
5925 * tests/modules.at (modules: importing): Apply some lateral
5926 thinking, and use AT_CHECK to compare the output of a sed pass
5927 over stderr against the canonical strerror string.
5929 * tests/modules.at (modules: importing): Edit the generated stderr
5930 output to canonicalize strerror output, before a comparison.
5932 2003-10-10 Gary V. Vaughan <gary@gnu.org>
5934 Tru64UNIX perl is sloppy with namespace pollution. This patch is
5935 careful not to trip over the mess:
5937 * modules/perl.c: Some builds of perl install headers that contain
5938 `#define try __builtin_try'. Be sure to undefine that macro
5939 before `m4/hash.h' gets included, which uses the `try' symbol.
5940 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
5941 `false' before including `stdbool.h'.
5942 (DELETE): This symbol is not in m4's namespace, and is in any
5943 case only used internally...
5944 * m4/m4private.h (DELETE): ...so move it to here.
5945 Reported by Martin MOKREJS <mmokrejs@natur.cuni.cz>
5947 2003-10-08 Paul Eggert <eggert@twinsun.com>
5949 Don't use XMALLOC and XCALLOC. Once we install the
5950 corresponding patch into gnulib, this will fix some
5951 address-calculation overflow bugs on hosts where calloc (A, B)
5952 returns garbage when A*B overflows.
5954 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
5955 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
5956 xmalloc, XCALLOC with xcalloc.
5957 * m4/m4.c (m4_create): Likewise.
5958 * m4/m4private.h (m4_symbol_value_create): Likewise.
5959 * m4/output.c (m4_output_init): Likewise.
5960 * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise.
5961 * m4/syntax.c (remove_syntax_attribute): Likewise.
5962 * src/freeze.c (reload_frozen_state): Likewise.
5963 * src/main.c (main): Likewise.
5965 2003-10-07 Gary V. Vaughan <gary@gnu.org>
5967 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
5968 gnulib/acm4 directories for aclocal m4 macros.
5969 * gnulib/Makefile.am (EXTRA_DIST): Removed.
5970 (MAINTAINERCLEANFILES): Add Makefile.in.
5971 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
5972 modules we use.
5973 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
5974 * gnulib/import: New file. Temporary script for updating gnulib
5975 imported files, until gnulib-tool is working.
5976 * gnulib/config/codeset.m4, gnulib/config/error.m4,
5977 gnulib/config/exitfail.m4, gnulib/config/extensions.m4,

6013 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
6014 gnulib/acm4/xstrndup.m4: Reimported from CVS gnulib with
6015 gnulib/import script.
6016 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/error.c,
6017 gnulib/m4/error.h, gnulib/m4/exitfail.c, gnulib/m4/free.c,

6020 gnulib/m4/version-etc.c, gnulib/m4/version-etc.h,
6021 gnulib/m4/xalloc.h, gnulib/m4/xmalloc.c: Updated from CVS
6022 gnulib with gnulib/import script.
6023 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
6024 guards ready for gnulib-tool to autoupdate on import.
6025 * config/debug.m4, config/gmp.m4, config/m4-error.m4,
6026 config/m4-gettext.m4, config/m4-obstack.m4, config/m4-regex.m4,
6027 config/stackovf.m4: Moved from here...
6028 * acm4/debug.m4, acm4/gmp.m4, acm4/m4-error.m4,
6029 acm4/m4-gettext.m4, acm4/m4-obstack.m4, acm4/m4-regex.m4,
6030 acm4/stackovf.m4: ...to here, to separate aclocal macros from
6031 configure time helper scripts.
6032 * config/error.m4: Removed; superceded by gnulib/acm4/error.m4.
6033 * m4/hash.c, m4/m4.c, m4/macro.c, m4/module.c, m4/output.c,
6034 m4/path.c, m4/symtab.c, m4/syntax, m4/system_.h, modules/m4.c,
6035 src/main.c, src/stackovf.c: s/xfree/free/g to comply with new
6036 gnulib xalloc.h.
6037 * src/main.c (version_etc_copyright): Only output the current
6038 year.
6039 (version_etc): Call with new variadic API.
6041 2003-09-16 Gary V. Vaughan <gary@gnu.org>
6043 * gnulib/m4/version-etc.c, gnulib/m4/version-etc.h: Import
6044 version-etc module from CVS gnulib.
6045 * po/POTFILES.in: Add gnulib/m4/version-etc.c.
6046 * src/Makefile.am: Build it.
6047 * src/main.c: Use it.
6049 * gnulib/m4/exit.h: Import exit module from CVS gnulib.
6050 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
6051 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
6052 exit.h instead.
6054 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
6055 Gary V. Vaughan <gary@gnu.org>
6057 * bootstrap: Separate options.
6058 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
6059 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
6060 not set.
6061 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
6062 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
6063 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
6064 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
6065 $(LTLIBINTL) for gettext support on cygwin.
6066 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
6067 have $(LTLIBINTL) from the preloaded module la files.
6068 * README: Remove the warning about using --disable-nls on Windows
6069 machines.
6071 2003-09-15 Gary V. Vaughan <gary@gnu.org>
6073 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
6074 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
6075 is required.
6077 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6079 * doc/STYLE: Document the gnulib header naming conventions, and
6080 #include policy.
6081 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
6082 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,
6083 gnulib/m4/gettext.h, gnulib/m4/obstack.h, gnulib/m4/regex.h
6084 respectively.
6085 * gnulib/m4/Makefile.am: Remove the rules to build these headers.
6087 * gnulib/m4/strtol.c, gnulib/config/strtol.m4: Import strtol
6088 module from CVS gnulib.
6089 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
6090 (gl_FUNC_STRTOL): In favour of the module macro.
6092 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6094 Replace the getopt code with CVS gnulib getopt. The source files
6095 detect whether they are in a glibc environment and preprocess away
6096 all of the code if there is a system getopt, so we can compile
6097 them into the m4 executable unconditionally:
6099 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
6100 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
6101 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
6102 macros.
6103 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
6104 version.
6105 * src/Makefile.am: Adjust.
6106 * src/main.c: Always include our shipped getopt.h.
6107 * po/POTFILES.in: Use new location of getopt.c.
6109 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6111 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
6112 * config/Makefile.am: Removed. Automake 1.8 distributes the files
6113 in this directory automatically.
6114 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
6116 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
6117 isn't set yet.
6118 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
6119 inline.
6120 * modules/Makefile.am (pkglibexecdir): Set it here.
6121 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
6123 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
6124 Import regex module from CVS gnulib.
6125 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
6126 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
6127 do extra substitutions for Makefile.
6128 * configure.ac: Use it.
6129 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
6130 from regex_.h if necessary.
6131 * m4/system_.h: Include the correct version of regex.h.
6132 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
6133 version.
6134 * po/POTFILES.in: Use new location of regex.c.
6136 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
6137 realloc.c: automake distributes these files already.
6139 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6141 Replace the xstrzdup code by importing the xstrndup module from
6142 CVS gnulib, along with its dependencies: strndup and strnlen:
6144 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
6145 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
6146 gnulib.
6147 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
6148 gnulib/config/strndup.m4: Ditto wrt strndup.
6149 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
6150 strnlen.
6151 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
6152 However, contrary to gnulib, we install xstrndup.h.
6153 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
6154 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
6155 is an artifact of the old m4 portability layer.
6156 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
6157 * m4/system_.h: Include xstrndup.h.
6158 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
6160 2003-09-11 Gary V. Vaughan <gary@gnu.org>
6162 Reimport the latest xalloc module from CVS gnulib, and adjust the
6163 m4 sources to take advantage of xalloc xfree. Also create a new
6164 macro DELETE with the same semantics as the old m4 XFREE macro,
6165 and carefully tweak callers:
6167 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
6168 gnulib.
6169 * m4/utility.c (xfree): Removed. This function is now supplied by
6170 gnulib xalloc.
6171 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
6172 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
6173 * m4/symtab.c (m4_symtab_create): Ditto.
6174 * m4/system_.h: Removed XFREE redefine.
6175 (DELETE): New macro with same functionality as the original m4
6176 XFREE macro, but based on xalloc.h now. Changed all callers.
6177 * src/main.c (main): Use XMALLOC macro.
6178 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
6179 instead of XFREE.
6180 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
6182 2003-09-10 Gary V. Vaughan <gary@gnu.org>
6184 Import the xalloc module from CVS gnulib, along with its
6185 dependencies: exitfail, malloc and realloc. We had different
6186 semantics for our XFREE and a function xfree() not supplied by
6187 gnulib, so also a bit of work to keep everything running
6188 smoothly:
6190 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
6191 (gl_XALLOC): Use gnulib equivalents.
6192 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
6193 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
6194 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
6195 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
6196 realloc.
6197 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
6198 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
6199 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
6200 imported modules.
6201 (pkgincdir): Removed. Use pkgincludedir instead.
6202 * m4/m4private.h (XFREE): xfree already checks for NULL.
6203 * m4/system_.h: Use xalloc module, and remove macros already
6204 supplied by xalloc.h.
6205 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
6206 moved the old definition from m4/xmalloc.c to here for now.
6208 2003-09-09 Gary V. Vaughan <gary@gnu.org>
6210 Import the error and progname modules from CVS gnulib. Our old
6211 error.c subsumed the functionality of both, so a little adjustment
6212 was required to accomodate the split in sources. Also added more
6213 wrapper macros to choose between a system installed error.h or our
6214 shipped gnulib error module:
6216 * m4/error.c, m4/error.h: Removed.
6217 * m4/Makefile.am: Adjust.
6218 (pkgincdir): Removed. Use pkgincludedir instead.
6219 * m4/module.h, src/main.c: Don't include `m4/error.h'.
6220 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
6221 error.h.
6222 * gnulib/m4/progname.c: Imported from CVS gnulib.
6223 * gnulib/m4/progname.h: Ditto.
6224 * src/main.c: Adjust to use progname module.
6225 * gnulib/m4/error.c: Imported from CVS gnulib.
6226 * gnulib/m4/error_.h: Ditto.
6227 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
6228 if appropriate, and link a local error.h if the system version is
6229 missing.
6230 (libgnu_la_SOURCES) Add progname module sources.
6231 * gnulib/config/error.m4: Imported from CVS gnulib.
6232 * gnulib/config/strerror_r.m4: Ditto.
6233 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
6234 to have ERROR_H for Makefile substitutions and tell system.h
6235 whether the system error.h should be used, or a locally installed
6236 version.
6237 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
6239 2003-09-09 Gary V. Vaughan <gary@gnu.org>
6241 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
6242 s/gettext_.h/gettext.h/.
6244 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
6245 automake have been fixed.
6247 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
6248 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
6249 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
6250 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
6252 2003-09-09 Gary V. Vaughan <gary@gnu.org>
6254 The gnulib obstack module requires the gnulib gettext module for
6255 systems that do not have GNU gettext installed. Because we use
6256 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
6257 that directory incase it clashes with the system gettext.h. This
6258 delta uses gettext_.h and extra rules in the Makefile to make a
6259 link to gettext.h when needed:
6261 * Makefile.am (auxdir): Removed. No longer used.
6262 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
6263 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
6264 moved.
6265 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
6266 Makefile based build.
6267 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
6268 of the macros are kept.
6269 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
6270 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
6271 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
6272 distributes these automatically.
6273 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
6274 warning from automake-1.7a.
6275 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
6276 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
6277 all callers.
6278 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
6279 wrt. m4_FUNC_OBSTACK.
6280 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
6281 wrt. m4_sys_STACKOVF.
6282 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
6283 wrt. _m4_LIB_GMP, m4_LIB_GMP.
6284 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
6285 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
6286 respectively.
6287 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
6288 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
6289 gettext.h link on deficient systems.
6290 (pkginc_HEADERS): Mention $(GETTEXT_H).
6291 (EXTRA_HEADERS): Mention gettext.h.
6292 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
6293 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
6294 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
6295 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
6296 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
6297 gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
6298 gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
6299 gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
6300 gnulib/config/po.m4, gnulib/config/progtest.m4,
6301 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
6302 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
6304 2003-09-05 Gary V. Vaughan <gary@gnu.org>
6306 We can't mirror the gnulib directory structure here, since we need
6307 to be able to eg. `#include <m4/obstack.h>' from our source files,
6308 which is much easier if the local obstack.h is created in a
6309 directory named m4. Rather than trying to symlink everything into
6310 the m4 directory, now we build a libtool convenience library from
6311 the sources we get from gnulib and link that with libm4.la:
6313 * gnulib/config/extensions.m4: Imported from CVS gnulib.
6314 * gnulib/config/unlocked-io.m4: Ditto.
6315 * gnulib/m4/unlocked-io.h: Ditto.
6316 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
6317 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
6318 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
6319 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
6320 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
6321 * m4/Makefile.am: Adjust.
6322 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
6323 macros we redistribute.
6324 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
6325 library among others.
6326 (GNULIB_SRCS, GNULIB_MACROS): Removed.
6327 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
6328 * config/m4-obstack.m4: Adjust.
6329 * po/POTFILES.in: Adjust.
6330 * configure.ac: Reformatting. Call newly imported gnulib macros.
6331 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
6332 bogus calls of `#include "m4.h"'.
6333 * Makefile.am: INCLUDES has been deprecated in favour of
6334 AM_CPPFLAGS.
6335 * m4/Makefile.am: Ditto.
6336 * modules/Makefile.am: Ditto.
6337 * src/Makefile.am: Ditto.
6339 2003-09-05 Gary V. Vaughan <gary@gnu.org>
6341 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
6343 2003-09-04 Gary V. Vaughan <gary@gnu.org>
6345 Migrate the obstack support into the gnulib directories for easy
6346 synchronisation with upstream files in gnulib:
6348 * config/gnu-obstack.m4: Moved from here...
6349 * config/m4-obstack.m4: ...to here.
6350 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
6351 * m4/obstack.c, m4/obstack_.h: Moved from here...
6352 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
6353 * po/POTFILES.in: Adjust.
6354 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
6355 * m4/Makefile.am: Add a whole new section to link the obstack
6356 sources from the gnulib tree if necessary.
6357 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
6358 from gnulib.
6359 * config/m4-obstack.m4: Rewrite as a wrapper for
6360 gnulib/m4/obstack.m4.
6362 2003-09-04 Gary V. Vaughan <gary@gnu.org>
6364 GNU M4 currently builds with a number of files adapted from
6365 upstream sources. Recently the gnulib project on savannah.gnu.org
6366 has pulled together a great many of these externally maintained
6367 files. This delta is the beginnings of isolating those files
6368 maintained in gnulib to make it easy to synchronise M4 with the
6369 upstream files prior to releases.
6371 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
6372 directory.
6373 (SUBDIRS): Added new gnulib subdirectory.
6374 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
6375 * config/stdbool.m4: Moved from here...
6376 * gnulib/m4/stdbool.m4: ...to here.
6377 * m4/stdbool_.h: Moved from here...
6378 * gnulib/lib/stdbool_.h: ...to here.
6379 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
6380 distributed.
6381 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
6382 code to work with new stdbool_.h location.
6383 (gnulib_srcdir): New.
6385 2003-09-04 Gary V. Vaughan <gary@gnu.org>
6387 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
6388 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
6389 builds to work.
6390 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
6391 (EXTRA_DIST): Use it.
6393 * bootstrap: CVS autoreconf leaves file droppings. Remove
6394 aclocal.m4t incase autoreconf doesn't.
6396 2003-08-29 Gary V. Vaughan <gary@gnu.org>
6398 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
6399 the other gnulib imports, renamed to m4/obstack_.h.
6400 * m4/obstack.c: Updated from CVS gnulib.
6401 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
6402 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
6403 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
6404 about vpath already, and $top_srcdir upsets CVS Automake, so the
6405 $top_srcdir reference was removed.
6407 * m4/system-h.in: For consistency with the gnulib imports, renamed
6408 to m4/system_.h.
6409 * m4/Makefile (EXTRA_HEADERS): Adjust.
6410 * configure.ac (AC_CONFIG_FILES): Adjust.
6412 * m4/stdbool_.h: New file from gnulib for systems without their
6413 own.
6414 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
6415 * config/stdbool.m4: New file. Macros from gnulib for same.
6416 * configure.ac: Use it.
6418 2003-08-27 Gary V. Vaughan <gary@gnu.org>
6420 * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'`

6467 * src/main.c: Ditto.
6468 * src/stackovf.c: Ditto.
6470 * config/gmp.m4 (M4_AC_LIB_GMP): Use AC_INCLUDES_DEFAULT:
6471 ac_default_headers is an autoconf internal variable.
6472 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
6473 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
6475 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
6476 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
6477 delta.
6479 2003-08-15 Gary V. Vaughan <gary@gnu.org>
6481 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
6482 C99 bool.
6483 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
6484 possible or faking one with a typedef. Changed all callers.
6486 2003-08-15 Gary V. Vaughan <gary@gnu.org>
6488 Still cleaning up the users' module API, by taking out the stuff
6489 that isn't used by any existing modules, and moving specialised
6490 functions out of libm4 and into the module they are used by.
6492 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
6493 * m4/utility.c (m4_skip_space): ...to here the home of its only
6494 use, made static and renamed to `skip_space'. Changed all
6495 callers.
6496 * m4/m4module.h (m4_expand_ranges): Removed prototype.
6497 * m4/utility.c (m4_expand_ranges): Moved definition from here...
6498 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
6499 ltdl.
6500 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
6501 casting .
6502 * modules/gnu.c (builtin_syntax): Import and use in this
6503 builtin implementation.
6504 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
6505 Not used. Deleted.
6506 * m4/macro.c (trace_flush): Except here where the macro is now
6507 manually inlined.
6508 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
6509 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
6510 moved...
6511 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
6512 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
6514 2003-08-14 Gary V. Vaughan <gary@gnu.org>
6516 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
6517 compiler based AC_CHECK_HEADER that was introduced in
6518 autoconf-2.56.
6519 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
6520 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
6521 * configure.ac: Use renamed M4_AC_LIB_GMP.
6523 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
6524 macro that requires arguments! This stops the shell's bad
6525 substitution error at configure time.
6527 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
6528 variables to the testsuite shell. Set the value of USE_GMP so
6529 that the gmp test will run!
6530 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
6532 2003-08-11 Gary V. Vaughan <gary@gnu.org>
6534 Libltdl already has an excellent mechanism for accessing C symbols
6535 in modules. Lets use that! Remove all the exporting cruft and
6536 just use lt_dlsym in conjunction with a few conventions to
6537 simplify module writers' jobs. Also removed the table address
6538 caching code and otherwise simplified the module loader quite a
6539 bit. To access exported symbols in other modules, first the
6540 exporting module must name the symbols <modname>_LTX_<symname>,
6541 and the importing module must define a function type called
6542 <symname>_func. The importer then adds
6543 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
6544 that wishes to call out to the exported functions. Care must be
6545 taken that <symname> is non-NULL in the importing module incase
6546 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
6547 definition was in the importers source. Study
6548 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
6549 m4_module_import will attempt to automatically load a module
6550 required for symbol access if it is not loaded already.
6552 * TODO: Removed the items fixed in this delta.
6553 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
6554 module name.
6555 * m4/ltdl.h (lt_dlhandle_find): Declare it.
6556 * m4/module.c (m4_module_unload): Use it.
6557 * src/freeze.c (reload_frozen_state): Ditto.
6558 * m4/m4module.h (m4_export): Deleted. Removed all references.
6559 (M4_MODULE_IMPORT): New user convenience macro for importing
6560 arbitrary symbols from other modules.
6561 * m4/module.c (m4_module_import): New function to service
6562 M4_MODULE_IMPORT macro.
6563 (module_data): Removed. Looking up the tables on demand with
6564 lt_dlsym, rather than caching their addresses here simplifies the
6565 code substantially.
6566 (m4_get_module_builtin_table, m4_get_module_macro_table):
6567 Removed. Changed all callers.
6568 (set_module_macro_table, set_module_builtin_table): Renamed to
6569 install_macro_table and install_builtin_table respectively, and
6570 simplified now that the cache is no more.
6571 * modules/gnu.c (builtin_symbols): Use this new mechanism to
6572 import m4_dump_symbols from the m4 module.
6573 (builtin_esyscmd): Likewise for m4_set_sysval and
6574 m4_sysval_flush.
6575 * modules/m4.c (m4_export_table): Removed. Functions are
6576 addressed with the new mechanism which doesn't need this.
6577 (m4_set_sysval): New exported accessor function to prevent
6578 problems with variable access on inferior architectures.
6579 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
6580 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
6581 that we can have some type safety.
6582 * modules/modtest.c (export_test): C level exported function for
6583 testing the new import mechanism.
6584 * modules/import.c: New file for the import end of the test.
6585 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
6586 * tests/modules.at: New test cases for intermodule symbol
6587 importing.
6589 2003-08-07 Gary V. Vaughan <gary@gnu.org>
6591 * m4/m4module.c (m4_string): Moved from here...
6592 * m4/m4private.c (m4_string): ...to here.
6594 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
6596 2003-07-29 Gary V. Vaughan <gary@gnu.org>
6598 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
6599 already available to module writers through
6600 m4_{get,set}_nesting_limit_opt(), so moved from here...
6601 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
6602 (m4_create): Use it.
6604 2003-07-28 Gary V. Vaughan <gary@gnu.org>
6606 Aside from auditing path.c for m4module.h api obfuscation, this
6607 delta introduces the concept of private struct members in opaque
6608 data types to GNU m4: See the STYLE file for details.
6610 * TODO: Remind ourselves that a rewrite of path.c is needed.
6611 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
6612 Moved from here...
6613 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
6614 here and renamed. These type definitions are for internal api use
6615 only. Changed all callers.
6616 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
6617 Moved from here...
6618 * m4/path.c (search_path_env_init, search_path_add): ...to here
6619 and renamed. These calls were never used outside this file.
6620 Changed all callers.
6621 (dirpath): Moved functionality of this static declaration...
6622 * m4/m4private.h (struct m4): ...to this new internal only
6623 search_path field. Changed all callers.
6624 (m4__get_search_path): Added new internal api accessor.
6625 * m4/path.c (m4_search_path_info_new): Removed. Not used.
6626 (m4_include_init): Removed...
6627 * m4/m4.c (m4_create): ...because the new m4 field is now
6628 initialised here.
6629 (m4_delete): Recycle search_path memory.
6630 * src/main.c (main): Don't call m4_include_init now that it's
6631 gone!
6632 * doc/STYLE: Document convention for private fields in opaque
6633 ADTs.
6635 2003-07-24 Gary V. Vaughan <gary@gnu.org>
6637 Sometimes exporting the address of a symbol from a module isn't
6638 enough for other modules to call that symbol correctly. If
6639 custom data types are used for function parameters, they need to
6640 be known to the caller. This change introduces the concept of
6641 $(prefix)/include/modules/$(modulename).h to declare those
6642 structures. Also we move m4_dump_symbols from libm4 to the m4
6643 module to show this concept in action.
6645 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
6646 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
6647 exporting data structures from modules/m4.c.
6648 * modules/m4.c, modules/gnu.c: Include it.
6649 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
6650 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
6651 prototypes.
6652 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
6653 Moved from here...
6654 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
6655 ...to here, with slight renaming.
6656 (m4_export_table): Prototype and add m4_dump_symbols.
6657 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
6658 definition of m4_dump_symbols.
6659 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
6660 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
6662 2003-07-24 Gary V. Vaughan <gary@gnu.org>
6664 Create an export table in modules/m4.c in readiness for beefing up
6665 the module loader to track module exports and imports.
6667 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
6668 * m4/debug.c (m4_debug_flush_files): Moved...
6669 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
6670 * modules/gnu.c (builtin_esysval): Use it.
6671 * m4/m4module.h (m4_export): New type for declaring module symbols
6672 for export.
6673 * modules/m4.c (m4_export_table): List symbols exported from this
6674 module for use by other modules.
6676 2003-07-24 Gary V. Vaughan <gary@gnu.org>
6678 An experiment: There is loads of code in libm4 which should be in
6679 the m4 module, but is also used by another module. Just because
6680 some linkers won't cope with calls across dynamic runtime loaded
6681 objects I initially left the code in libm4. It will tidy the
6682 module api immensely if this code moves to the right place, I just
6683 need to remember to invent a suitable calling mechanism at some
6684 point. For now, only modules that are statically linked and
6685 preloaded will get this treatment, so the only platforms that will
6686 break are those that require all symbols to be resolved at link
6687 time.
6689 * TODO: Reminder that what I am doing could reduce portability
6690 unless I do something more robust later.
6691 * m4/m4module.h (m4_sysval): No longer exported from libm4.
6692 * m4/utility.c (m4_sysval): No longer declared in libm4.
6693 * modules/Makefile.am: Reformatting.
6694 * modules/m4.c (m4_sysval): Declare it at place of use.
6695 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
6697 2003-07-23 Gary V. Vaughan <gary@gnu.org>
6699 * m4/m4module.h: Reformatting and rearranging lines a bit.
6700 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
6701 all users.
6702 (m4_call_macro, m4_expand_input): Renamed...
6703 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
6704 callers.
6705 (m4_expansion_level, m4_process_macro): Moved...
6706 * m4/macro.c (expansion_level, process_macro): ...to here, and
6707 made static.
6709 * m4/m4module.h (program_name): Not used by modules at all, so
6710 moved...
6711 * src/main.c (program_name): ...to here.
6712 (print_program_name): Renamed...
6713 (print_program_name_CB): ...to conform to the STYLE guide.
6715 2003-07-23 Gary V. Vaughan <gary@gnu.org>
6717 More refactoring of the m4module.h API. Replace #defines with an
6718 enum, and move non-public functions out of the public API.
6720 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
6721 inclusion.
6722 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
6723 * m4/debug.c (m4_debug, trace): Moved...
6724 * m4/m4private.h (struct m4): ...to fields of this struct.
6725 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
6726 for the new fields.
6727 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
6728 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
6729 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
6730 * m4/m4module.h (m4_context_field_table): Add entries for new
6731 debug_file and trace_messages fields.
6732 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
6733 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
6734 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
6735 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
6736 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
6737 (m4_is_debug_bit): New macro to simplfy checks against the debug
6738 bits above.
6739 (m4_trace_format, m4_trace_header, m4_trace_flush)
6740 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
6741 prototypes.
6742 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
6743 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
6744 * m4/macro.c (trace_format, trace_header, trace_flush)
6745 (trace_prepre, trace_pre, trace_post): ...to these newly static
6746 functions, since they are only ever used from this file. Changed
6747 all callers.
6749 2003-07-17 Gary V. Vaughan <gary@gnu.org>
6751 Change the macros for checking syntax so that matching against
6752 multiple possible syntax classes can be done with a single
6753 comparison some of the time. The various classes are now bits of
6754 an int that can be checked with bitwise logic operators.
6756 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
6757 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
6758 (M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)
6759 (M4_SYNTAX_ASSIGN, M4_SYNTAX_ALPHA, M4_SYNTAX_NUM)
6760 (M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)
6761 (M4_SYNTAX_ECOMM): Replaced #defines with an enum.
6762 (M4_SYNTAX_ALNUM): Removed. Changed all callers.
6763 (M4_IS_IGNORE, M4_IS_OTHER, M4_IS_SPACE, M4_IS_OPEN, M4_IS_CLOSE)
6764 (M4_IS_COMMA, M4_IS_DOLLAR, M4_IS_ACTIVE, M4_IS_ESCAPE)
6765 (M4_IS_ASSIGN, M4_IS_ALPHA, M4_IS_NUM, M4_IS_LQUOTE, M4_IS_RQUOTE)
6766 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
6767 Replace all calls with invocations of these...
6768 (m4_is_syntax, m4_has_syntax): ...New macros.
6769 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
6770 is no longer required with new macros. Changed all callers.
6772 2003-07-15 Gary V. Vaughan <gary@gnu.org>
6774 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
6775 values are returned as part of the internal interface, so they
6776 need to be moved...
6777 * m4/private.h: ...to here.
6778 * m4/macro.c (expand_token): Check for out of range
6779 m4_peek_input() results before looking up in the syntax table.
6780 (collect_arguments): Ditto.
6782 * NEWS: Note `$' syntax class.
6784 2003-07-08 Paul Eggert <eggert@twinsun.com> and
6785 Gary V. Vaughan <gary@gnu.org>
6787 Conform to POSIX if the POSIXLY_CORRECT environment is set.
6788 --traditional `define' now smashes all the definitions.
6790 * NEWS: Explain this.
6791 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
6792 (Extensions): Explain that extensions that are incompatible with
6793 POSIX are disabled if POSIXLY_CORRECT is set.
6794 (Incompatibilities): Remove.
6795 (Define, Other Incompat): Explain difference
6796 between GNU and POSIX behavior of define, pushdef, popdef.
6797 * m4/m4.c (m4_get_posixly_correct_opt): New undef.
6798 * m4/m4module.h (m4_context_opt_bit_table): Add POSIXLY_CORRECT entry.
6799 * m4/m4private.h (M4_OPT_POSIXLY_CORRECT_BIT): New macro.
6800 (m4_get_posixly_correct_opt): New macro.
6801 * m4/m4macro.c (m4_process_macro): Disable $10, $abc etc. if
6802 POSIXLY_CORRECT.
6803 * modules/m4.c (builtin_functions): defn now takes any number of args.
6804 (builtin_define): Smash all the definitions if
6805 POSIXLY_CORRECT.
6806 (builtin_defn)): Allow any number of arguments.
6807 (builtin_undivert): Do not allow nonnumeric arguments
6808 if POSIXLY_CORRECT.
6809 * src/main.c (main): Set posixly-correct behavior if either
6810 POSIXLY_CORRECT is set, or if -G is given.
6811 * tests/builtins.at: New test for smashed definitions.
6813 2003-06-27 Gary V. Vaughan <gary@gnu.org>
6815 * doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
6816 * m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
6817 not to slow the parser down.
6818 (M4__IS_STRING): New macro to test string syntax class membership.
6819 * m4/syntax.c: Adjust docucomment.
6820 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
6821 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
6822 * m4/input.c (init_builtin_token): Comment typo.
6823 (m4__next_token): Comment typo.
6824 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
6825 by using the new M4__IS_STRING macro.
6826 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
6827 variable references in macro expansions.
6829 * doc/m4.texinfo (Eregexp and Regexp): Typo.
6830 (Epatsubst and Patsubst): Typo.
6831 (Eval): Typo.
6833 2003-06-26 Gary V. Vaughan <gary@gnu.org>
6835 Move the global variables that pertain to syntax to a new `struct
6836 m4_syntax_table', and then add one of these to `struct m4'. The
6837 ripple effect through the code to both change formerly global
6838 references, and make sure a suitable context is available in
6839 lexical scope is disproportionately large compared to the size of
6840 the change proper. This change is a large part of decoupling
6841 syntax.c from the rest of the code that uses it.
6843 * m4/m4private.h (struct m4): Add a syntax field.
6844 * m4/m4.c (m4_create): Initialise it,
6845 (m4_delete): Recycle it.
6846 (m4_get_symtab): Remove hand coded version...
6847 (m4_get_symbol_table): ...and generate this with cpp. Changed all
6848 callers.
6849 * m4/m4module.h (m4_context_field_table): Add an extra field so we
6850 can generate m4_get_symbol_table. Add a new row for
6851 m4_get_syntax_table.
6852 (M4SYNTAX): Syntactic sugar for module writers.
6853 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
6854 (m4_syntax_table): New home for syntax related formerly global
6855 variables.
6856 * m4/m4private.h (struct m4_syntax_table): Define it.
6857 * m4/input.c (m4_input_init): Initialisation of these formerly
6858 global variables moved...
6859 * m4/syntax.c (m4_syntax_create): ...to here.
6860 * m4/input.c (m4_input_exit): And similarly, recycling of the
6861 memory used by those values moved...
6862 * m4/syntax.c (m4_syntax_delete): ...to here.
6863 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
6864 Moved to m4/m4private.h.
6865 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
6866 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
6867 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
6868 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
6869 objects. Changed all callers that used to directly access the
6870 global equivalents.
6871 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
6872 Removed and incorporated into m4_syntax_table structure.
6873 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
6874 * m4/syntax.c (m4_set_syntax): Now returns an error status,
6875 instead of requiring a `struct m4' to generate its own errors.
6876 Changed all callers.
6877 * src/main.c (main): Now that the syntax table is initialised as
6878 part of m4_create, we have to manually wipe the syntax entries if
6879 we are about to read a frozen file.
6881 2003-06-26 Gary V. Vaughan <gary@gnu.org>
6883 * doc/STYLE: Added notes on callback naming schemes.
6885 * m4/module.c (m4_set_module_macro_table)
6886 (m4_set_module_builtin_table): Declarations weren't changed when
6887 definitions were renamed on 2003-06-19.
6889 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
6890 neither used nor particularly appropriate since it exposes the
6891 internal workings of the hash module. I haven't yet decided
6892 whether to remove it entirely.
6894 2003-06-20 Gary V. Vaughan <gary@gnu.org>
6896 Two related changes, and a huge knockon effect throughout the
6897 source: Moved the option variables out of global space and into
6898 `struct m4'; made `m4_symtab' a real datatype, so that its api
6899 is not marred passing `struct m4' around just so it can decide
6900 whether to keep traced symbol names or not. Added setters and
6901 getters for the formerly global option variables, and obviously
6902 changed a vast number of functions to take a `struct m4' and use
6903 the getter funcs to find option values.
6905 * m4/utility.c (interactive, sync_output, debug_level)
6906 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
6907 (max_debug_argument_length, warning_status, nesting_limit)
6908 (discard_comments): Removed.
6909 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
6910 (debug_level, max_debug_argument_length, prefix_all_builtins)
6911 (suppress_warnings, discard_comments, interactive, sync_output):
6912 Removed from here...
6913 * m4/m4private.h (struct m4): ...and equivalent fields added to
6914 this structure.
6915 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
6916 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
6917 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
6918 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
6919 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
6920 macros for the new fields.
6921 * m4/m4module.h (m4_context_field_table)
6922 (m4_context_opt_bit_table): Helper macros used to generate
6923 prototypes, setters and getters for new option fields
6924 consistently.
6925 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
6926 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
6927 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
6928 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
6929 (m4_get_interactive_opt, m4_get_sync_output_opt)
6930 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
6931 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
6932 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
6933 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
6934 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
6935 setter and getter functions generated by cpp from
6936 m4_context_field_table and m4_context_opt_bit_table, exported as
6937 part of the module api. Changed all callers.
6938 * m4/symtab (struct m4_symtab): Used as the concrete type for
6939 m4_symtab now.
6940 (m4_symtab_create): Allocate and initialise a new struct.
6941 (m4_symtab_apply): New function that works like m4_hash_apply, but
6942 with different callbacks specific to symbol tables. Changed all
6943 callers.
6944 (symbol_destroy, arg_destroy, arg_copy): Renamed
6945 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
6946 they have unused parameters for a reason!
6947 (dump_symbol_CB): New callback to dump the contents of a single
6948 symbol.
6949 (symtob_dump): Rewritten in terms of dump_symbol_CB.
6950 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
6951 Changed all callers.
6952 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
6953 of the contained `m4_symtab' at the `no_gnu_extensions' field.
6954 Although I'm not convinced these semantics are correct, they are
6955 at least consistent with how things were before this delta. Also
6956 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
6958 2003-06-19 Gary V. Vaughan <gary@gnu.org>
6960 Tie down the interface to libm4 some more. Make more structures
6961 opaque to modules by moving them to m4private.h, and writing
6962 setters and getters. To win back the speed penalty for doing this
6963 also wrote macroized versions that do know about structure layout
6964 in m4private.h and #include that file into modules when NDEBUG is
6965 defined at compile time. There are still some accessor macros in
6966 m4private.h that need to go, but that is not necessary to clean
6967 the module api up.
6969 * m4/m4module.h (m4_symbol_type): Moved...
6970 * m4/m4private.h (m4__symbol_type): ...to here.
6971 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
6972 (m4_set_symbol_traced, m4_set_symbol_name_traced)
6973 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
6974 (m4_get_symbol_func, m4_symbol_value_create)
6975 (m4_symbol_value_delete, m4_set_symbol_value_text)
6976 (m4_set_symbol_value_func): New exported api to symbols.
6977 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
6978 and m4_is_symbol_value_func.
6979 * m4/m4module.h: Prototype these guys.
6980 * m4/module.c (m4_set_module_macro_table)
6981 (m4_set_module_builtin_table): Make these static, there is no
6982 reason to pollute the api with them.
6983 * m4/m4private.h: Reformatting.
6984 (m4_get_symtab): Only define when NDEBUG is defined.
6985 (m4_get_symbol_value, m4_get_symbol_traced)
6986 (m4_set_symbol_traced, m4_set_symbol_name_traced)
6987 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
6988 (m4_get_symbol_func, m4_symbol_value_create)
6989 (m4_symbol_value_delete, m4_set_symbol_value_text)
6990 (m4_set_symbol_value_func): Macro implementations of the new
6991 functions when NDEBUG is defined.
6992 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
6993 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
6994 Superceded by the above. All callers changed.
6995 (M4ARG): Removed. This is no longer different to the
6996 m4/m4module.h definition.
6997 * modules/gnu.c, modules/m4.c: Only include m4private.h when
6998 NDEBUG is defined. That way we exercise the same (albeit slower)
6999 api that external modules must use.
7001 2003-06-18 Gary V. Vaughan <gary@gnu.org>
7003 Renamed some of the types and their accessors to make more sense.
7004 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
7005 has a stack of SYMBOL_VALUEs.
7007 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
7008 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
7009 m4_get_symbol_value_type, m4_get_symbol_value_text,
7010 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
7011 Changed all callers.
7012 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
7013 (m4_get_token_type): Renamed
7014 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
7015 to the internal api.
7016 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
7017 s/TOKEN_/VALUE_/
7018 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
7019 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
7020 (m4__token_type): Moved here from m4module.h.
7021 (m4__next_token): Renamed from m4_next_token.
7022 * m4/symtab.c: Removed some of the parameterised macro support
7023 functions for modularisation later.
7024 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
7025 m4_hash_dup to perform a true deep copy of the SRC.
7026 (arg_copy): Callback for m4_symbol_value_copy.
7027 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
7028 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
7029 m4_get_symbol_value_func. Changed all callers.
7031 2003-06-18 Gary V. Vaughan <gary@gnu.org>
7033 Tidy up style of hash.[ch] in accordance with doc/STYLE.
7035 * m4/hash.c: Internal symbol renaming and formatting.
7036 (m4_hash_dup): New function to facilitate deep copies of hash
7037 tables.
7038 (m4_hash_apply_func): Returns a void* now, which is a richer type
7039 for returning exceptions (NULL means keep going).
7040 (m4_hash_apply): Ditto.
7041 * m4/hash.h: Declare exported symbols with an explicit extern.
7042 Reformated.
7044 2003-06-17 Gary V. Vaughan <gary@gnu.org>
7046 Still refactoring furiously. This delta represents a change in
7047 semantics to symtab.c. Instead of building temporary m4_tokens
7048 in the caller, and copying fields in the methods, we now create
7049 the actual m4_token for hashing in the caller so the methods just
7050 slot them in directly. Also, this means that we don't lookup a
7051 symbol and get back an allocated but VOID token to copy fields
7052 into, we create the token we want to push and pass that to
7053 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
7054 a few other small changes to stop knowledge of the implementation
7055 of symtab.c leaking out into other files.
7057 * m4/macro.c (expand_argument): Comment typo corrected.
7058 * m4/symtab.c (symtab_fetch): New function to fetch the address of
7059 an interned symbol.
7060 (m4_symbol_pushdef): Take an extra value parameter and use this
7061 directly as the new top of the value stack. All callers changed
7062 to build a token and pass responsibility for memory in, rather
7063 than copying as we used to.
7064 (m4_symbol_define): Also use the new value parameter directly as a
7065 replacement for the top of the value stack. All callers changed
7066 to build a token as above.
7067 (m4_set_symbol_traced): New function to set the traced bit on the
7068 named symbol, creating it if necessary.
7069 (symbol_popval): The guts of the old m4_symbol_popdef.
7070 (m4_symbol_popdef): Use it.
7071 * m4/builtin.c (m4_symbol_set_token): Removed,
7072 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
7073 replaced...
7074 * m4/module.c (m4_set_module_builtin_table)
7075 (m4_set_module_macro_table): ...with these more orthogonal
7076 functions.
7077 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
7078 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
7079 required.
7080 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
7081 (m4_arg_signature_parse): Moved...
7082 * m4/symtab.c: ...to here.
7083 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
7084 screw something up. Moved...
7085 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
7086 actually does a proper deep copy of source to dest.
7088 2003-06-16 Gary V. Vaughan <gary@gnu.org>
7090 Further refactoring to stabilise the module API. Renaming some
7091 functions for orthogonality, and judicious definition migration to
7092 move things out of the set of exported symbols.
7094 * doc/STYLE: New file. Notes on coding style.
7095 * m4/m4module.c: Updated bitrotted docucomment at the top of the
7096 file.
7097 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
7098 m4_get_module_name, m4_get_module_builtin_table,
7099 m4_get_module_macro_table which are verb phrases. Changed all
7100 callers.
7101 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
7102 Moved to...
7103 * m4/module.c (m4_set_module_builtin_table)
7104 (m4_set_module_macro_table): ...here, and renamed. Changed all
7105 callers.
7106 * m4/m4module.c (m4_module_data): This...
7107 * m4/m4private.c (struct m4_module_data): ...and this...
7108 * m4/module.c (module_data) ...consolidated here and no longer
7109 exported. Changed all callers.
7111 2003-06-16 Gary V. Vaughan <gary@gnu.org>
7113 Begin work on lifting the curse of the global variables. To start
7114 with create a `struct m4' context container, and replace
7115 `m4__symtab' with `context->symtab' throughout. This means
7116 initialising a context container in main, and adjusting many
7117 functions between main and the module entry points so that the
7118 container gets passed through. It would have been nice to
7119 defer this until after 1.5, but it has a major effect on the
7120 user's module writing ABI, so it needs to be addressed now - at
7121 least in the areas that impact the ABI. An interrelated change
7122 in the symtab API removes the dependency on a global symbol table,
7123 and instead focuses on a passed table (from the context
7124 container).
7126 * TODO: Reminders for finishing context functionality.
7127 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
7128 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
7129 global variables and eventually allow m4 to be reentrant.
7130 * m4/m4private.h (m4): Define the new structure here...
7131 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
7132 don't carry the overhead of a function call.
7133 * m4/m4module.h: Prototype extern functions from m4/m4.c.
7134 (m4): Declare type for new struct m4 objects.
7135 (M4SYMTAB): User macro to ease finding the symbol table for the
7136 current context for module developers.
7137 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
7138 verb.
7139 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
7140 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
7141 (m4_call_macro, m4_dump_symbols, m4_expand_input)
7142 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
7143 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
7144 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
7145 m4* context parameter. Changed definitions and all callers.
7146 (m4_symtab): Alias for m4_hash to decouple the
7147 m4_symtab api from m4_hash.
7148 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
7149 m4_hash.
7150 (m4_symtab_create): New function to return an initialised
7151 m4_symtab.
7152 (m4_symtab_delete): New function to delete an m4_symtab's memory.
7153 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
7154 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
7155 instead of simply using the global m4__symtab. Changed
7156 definitions and all callers.
7157 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
7158 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
7159 * src/main.c (main): Create a context and use that instead of the
7160 former global m4__symtab.
7162 2003-06-13 Gary V. Vaughan <gary@gnu.org>
7164 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
7165 to the callback. Callbacks should not need to hardcode the
7166 hashtable they are working from, nor should we have to waste the
7167 userdata parameter to pass the table in.
7168 * m4/hash.h (m4_hash_apply_func): Require the initial table
7169 parameter.
7170 * m4/symtab.c (symtab_destroy): Use the passed table instead
7171 of hardcoding m4__symtab.
7172 (m4_symbol_popdef): Don't use the userdata parameter to pass the
7173 table to arg_destroy.
7174 (arg_destroy): Use the hash parameter, ignore userdata.
7175 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
7176 prototype.
7177 (traceon, traceoff): Call set_trace with the extra initial
7178 parameter.
7180 2003-06-13 Gary V. Vaughan <gary@gnu.org>
7182 More refactoring to stabilise the module api, this time for
7183 symtab.c. Additionally, start to pay attention to function names
7184 that don't contain a verb like they should.
7186 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
7187 wrapper for m4_hash_apply to decouple the symtab module from the
7188 hash module.
7189 (m4_symbol_builtin, m4_symbol_macro): Renamed to
7190 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
7191 callers.
7192 (m4_symbol_delete): Create a macro version to save a function
7193 call.
7194 (m4_token_t, m4_data_t): These violate the POSIX reserved
7195 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
7196 all callers.
7197 (m4_token_type): Renamed to m4_token_get_type.
7198 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
7199 (m4_symtab_exit): Removed from the exported module
7200 api...
7201 * m4/m4private.h (m4__symtab, m4__symtab_init)
7202 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
7203 renamed and added to the internal api. Changed all callers.
7204 (m4_symtab_apply): A faster macro version of the function for
7205 users of the internal api.
7206 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
7207 symbol_destroy and arg_destroy.
7208 (symtab_debug): Added a prototype.
7209 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
7210 so that callers in this file get the faster macro versions from
7211 m4/m4private.h.
7213 2003-06-12 Gary V. Vaughan <gary@gnu.org>
7215 Refactoring modules to rationalise the API into an external
7216 documented (eventually!) API for use by modules in the `m4_'
7217 namespace declared in m4/m4module.h, an internal API between the
7218 source files we ship (including our shipped modules) in the `m4__'
7219 namespace declared in m4/m4private.h and making the rest as
7220 cohesive as possible with liberal use of the `static' keyword.
7221 This change represents an audit to m4/module.c along these
7222 guidelines.
7224 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
7225 Removed. No longer used.
7226 (m4_module_close): Removed prototypes.
7227 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
7228 from the exported module api...
7229 * m4/m4private.h (m4__module_init, m4__module_open)
7230 (m4__module_exit): ...and renamed and added to the internal api.
7231 Changed all callers.
7232 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
7233 Centralised definitions after renaming...
7234 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
7235 (M4_FINISH_SYMBOL): ...and removing from here.
7236 (m4_module_dlerror, m4_module_remove, m4_module_close)
7237 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
7238 module_remove, module_close and caller_id.
7239 (MODULE_SELF_NAME): New macro to make reporting self errors
7240 easier.
7241 (m4_module_load, module_close, module_remove): Use it.
7242 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
7243 name.
7244 * src/main.c (main): Use it.
7246 2003-06-12 Gary V. Vaughan <gary@gnu.org>
7248 * README: Remove references to --enable-changeword, which has been
7249 removed from the code.
7251 2003-06-11 Gary V. Vaughan <gary@gnu.org>
7253 Getting rid of the annoying bug with configure --enable-debug,
7254 which spewed -e: command not found errors. This was an interaction
7255 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
7256 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
7257 branch-1-5) to get the full fix.
7259 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
7260 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
7261 and then use the probed value of $SED.
7262 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
7263 this, it messes up the AC_REQUIRE stack.
7265 2003-06-10 Gary V. Vaughan <gary@gnu.org>
7267 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
7268 the destroy callback.
7269 (m4_arg_destroy): Use the hash address to free the hash node key
7270 field.
7272 2003-06-06 Gary V. Vaughan <gary@gnu.org>
7274 First cut at formal parameters in macros.
7276 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
7277 * m4/xstrzdup.c: New file.
7278 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
7279 associative array of parameter names to details.
7280 (m4_symbol_token): Capture macro names with parameter lists.
7281 (m4_arg_signature_parse): And build an associative array to hang
7282 from the symbol structure to map names to details.
7283 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
7284 m4_hash_resize idiom. Now that we potentially add a little hash
7285 table to many of the entries in the symbol table, added an extra
7286 arg to set the initial size. Changed all callers.
7287 (m4_hash_apply): New function that is basically a generalised
7288 version of...
7289 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
7290 all callers to call m4_hash_apply instead.
7291 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
7292 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
7293 m4_arg_signature association that might be attached to the symbol,
7294 * m4/hash.h (m4_hash_apply_func): Replacement type for...
7295 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
7296 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
7297 parameter lists.
7298 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
7299 (M4_IS_IDENT): Detect characters that can be safely used in
7300 parameter names.
7301 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
7302 * m4/macro.c: Corrected grammar in some comments. Use `token'
7303 rather than `td' for m4_token variables.
7304 (m4_process_macro): If we find a dollar followed by some
7305 M4_IS_IDENT characters, replace that with the contents of the argv
7306 entry with offset stored in the m4_token_arg associated with the
7307 collected identifier.
7309 2003-06-05 Gary V. Vaughan <gary@gnu.org>
7311 Begin preparations for supporting formal parameters in m4 macros.
7313 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
7314 the details of a formal parameter.
7315 (m4_token): Add an arg_signature member to hold a hash table for
7316 looking up formal parameters.
7317 * m4/input.c: Update more bitrotted comments.
7318 (m4_push_builtin): Initialise arg_signature member.
7319 (init_builtin_token): Copy arg_signature member.
7320 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
7321 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
7322 replace...
7323 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
7324 (m4_macro_pushdef, m4_macro_define): ...these, And...
7325 (m4_symbol_token): ...wrapped around this new function, which
7326 vastly simplifies the arguments required by the functions it
7327 replaces.
7328 Changed all callers.
7330 2003-06-05 Gary V. Vaughan <gary@gnu.org>
7332 * m4/macro.c: Format changes.
7334 2003-06-04 Gary V. Vaughan <gary@gnu.org>
7336 * m4/input.c: Updated various bitrotted comments.
7337 (m4_push_builtin): Just pass the whole m4_token, rather than
7338 extracting all the fields in the caller. This also allows us to
7339 check the token type for consistency.
7340 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
7341 Renamed to builtin_funcs, builtin_peek, builtin_read,
7342 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
7343 the code. Changed all callers.
7344 (struct input_block): Similarly renamed u_m member to u_b, and
7345 changed all callers.
7346 (m4_next_token): Use bzero to initialise the data fields.
7347 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
7349 2003-05-29 Gary V. Vaughan <gary@gnu.org>
7351 These changes were necessary to get m4 to build on my iBook
7352 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
7353 (GCC) 3.1 20020420 (prerelease)":
7355 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
7356 inclusion of module loader headers.
7357 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
7358 * m4/Makefile.am: Ditto.
7359 (libm4_la_LIBADD): Added $(LTLIBINTL).
7360 * m4/utility.c (program_name): Removed declaration in favour of
7361 the one already in error.c!
7362 * m4/m4module.h (program_name): Define to program_invocation_name
7363 when using GNU C library. Use an explicit extern declaration.
7364 (interactive, sync_output, debug_level, hash_table_size)
7365 (no_gnu_extensions, prefix_all_builtins, max_debug_argument_length)
7366 (suppress_warnings, warning_status, nesting_limit, discard_comments)

7374 (m4_current_line, m4_current_diversion, m4_output_current_line):
7375 Don't rely on default, use an explicit extern.
7376 * m4/error.h (error, error_at_line, error_print_progname)
7377 (error_message_count, error_one_per_line): Ditto.
7378 * m4/ltdl.c: Update from CVS libtool.
7379 * m4/ltdl.h: Ditto.
7380 * commit: Update from CVS cvs-utils.
7382 2002-11-04 gettextize <bug-gnu-gettext@gnu.org>
7384 * po/Makefile.in.in: Upgrade to gettext-0.11.5.

7393 2002-11-04 Akim Demaille <akim@epita.fr>
7395 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
7396 running m4 itself.
7397 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
7399 2002-11-04 Akim Demaille <akim@epita.fr>
7401 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
7403 2002-11-04 Akim Demaille <akim@epita.fr>
7405 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
7406 used as `external', and Libtool 1.4.3.
7407 (LINGUAS): Remove.
7408 (LTLIBOBJS): Don't play with it.
7409 * intl/: Remove.
7410 * Makefile.am (SUBDIRS): Remove intl.
7411 (ACLOCAL_AMFLAGS): Add -I config.
7412 (EXTRA_DIST): Add config/config.rpath.
7413 * po/LINGUAS: New.
7414 * po/Makevars: New.

7417 2002-05-29 Gary V. Vaughan <gary@gnu.org>
7419 Preparations for refactoring syntax tables to allow reverse
7420 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
7421 speed of normal lookups in an array of unsigned short.
7423 * m4/input.c (single_quotes, single_comments, use_macro_escape):
7424 Moved from here...
7425 * m4/m4private.h (m4__single_quotes, m4__single_comments,
7426 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
7427 is for internal symbols which unavoidably pollute the global
7428 namespace, but are not published APIs.
7429 Adjusted all callers.
7430 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
7431 m4_set_comment, m4_set_syntax, set_syntax_internal,
7432 unset_syntax_attribute): Moved from this file...
7433 * m4/syntax.c: New. ...to this file.
7434 Also added an m4_syntax_exit stub for orthogonality.
7435 * src/main.c (main): Use it.
7436 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
7437 * m4/m4module.h: Reformatting. New prototypes.
7439 2002-05-29 Gary V. Vaughan <gary@gnu.org>
7441 * bootstrap (aclocal_apiversion): The aclocal apiversion is
7442 distinct from the automake release number (in that the apiversion
7443 apparently has no micro-version-component).
7444 (aclocal_apilibdir): Use it.
7446 2002-05-28 Gary V. Vaughan <gary@gnu.org>
7448 * m4/hash.c (m4_hash_resize): New function.
7449 * m4/hash.h: Add prototype.
7450 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
7451 benchmarking to find a good value for, say, autoconf. This is
7452 already a little quicker than before for me.
7454 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
7455 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
7456 and reenamed.
7457 * m4/hash.h: Adjust prototypes.
7459 2002-01-22 Akim Demaille <akim@epita.fr>
7461 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
7462 APIVERSION scheme.
7463 * tests/Makefile.am (package.m4): New.
7464 * tests/atlocal.in: Adjust to CVS Autotest.
7465 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
7466 * configure.ac: LIBOBJ is a forbidden string.
7467 Simplify AM_INIT_AUTOMAKE invocation.
7468 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
7469 options.m4.
7471 2002-01-21 gettextize <bug-gnu-utils@gnu.org>
7473 * po/Makefile.in.in: Upgrade to gettext-0.10.40.
7475 2001-10-19 Akim Demaille <akim@epita.fr>
7477 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
7479 2001-10-19 Akim Demaille <akim@epita.fr>
7481 * m4/input.c (m4_next_token): Display where was opened what is
7482 not closed.
7484 2001-10-19 Akim Demaille <akim@epita.fr>
7486 * m4/macro.c (expand_argument): Display where was opened what is
7487 not closed.
7489 2001-10-18 Akim Demaille <akim@epita.fr>
7491 * m4/input.c, modules/m4.c: Formatting changes.
7493 2001-10-17 Gary V. Vaughan <gary@gnu.org>
7495 * bootstrap: s/configure.in/configure.ac/
7497 2001-10-16 Gary V. Vaughan <gary@gnu.org>
7499 * m4/symtab.c (m4_symbol_destroy): This function calls
7500 m4_symbol_popdef, which recycles a symbols memory when the last
7501 definition is popped. Since we were passing the address of the
7502 symbol name found in the symbol table, and it was being removed
7503 partway through m4_symbol_destroy() we were referencing freed
7504 memory for the balance of the function. Now we take a copy of the
7505 symbol name tring and use that as a key into the symbol
7506 table... that way if the original symbol name is freed, the copy
7507 is still valid.
7509 2001-10-13 Akim Demaille <akim@epita.fr>
7511 * m4/ltdl.c: Update.
7513 2001-10-13 Akim Demaille <akim@epita.fr>
7515 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
7516 Don't gettextize internal error messages.
7518 2001-10-13 Akim Demaille <akim@epita.fr>
7520 * tests/macros.at (Arity and defn): New failing test.
7521 (Arity, defn, and freeze): New.
7523 Fix `Arity and defn'.
7525 * m4/input.c (m4_push_macro): Don't forget the arity.
7526 * modules/m4.c (defn): Likewise.
7528 2001-10-13 Akim Demaille <akim@epita.fr>
7530 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
7531 to...
7532 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
7533 (Propagation of traceon, Propagation of --trace): this new file.
7535 2001-10-13 Akim Demaille <akim@epita.fr>
7537 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
7538 interface instead of (name, argc...).
7539 Upon failure, specify which argument was guilty.
7540 Adjust callers.
7542 2001-10-13 Akim Demaille <akim@epita.fr>
7544 * modules/evalparse.c: Save translators' time: don't translate
7545 internal error messages.
7546 (m4_evaluate): Simplify/normalize error messages.
7547 * doc/m4.texinfo (Eval): Adjust.
7549 2001-10-13 Akim Demaille <akim@epita.fr>
7551 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
7552 where no checking is needed.
7553 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
7554 interface instead of (name, argc...).
7555 Adjust callers.
7556 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
7557 elsewhere.
7559 2001-10-13 Akim Demaille <akim@epita.fr>
7561 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
7562 exclude the builtin name from the count.
7563 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
7564 calling ifelse with a single argument is valid.
7565 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
7566 with 1 and 2 args, mostly to strengthen the test suite.
7568 2001-10-13 Akim Demaille <akim@epita.fr>
7570 * m4/output.c (m4_make_diversion, m4_insert_file)
7571 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
7573 2001-10-12 Gary V. Vaughan <gary@gnu.org>
7575 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
7576 since we call these things builtins in the rest of the code!
7578 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
7580 2001-10-12 Gary V. Vaughan <gary@gnu.org>
7582 Rather than forcing each builtin definition to manage its own
7583 argument range checking, tabulate the maxima and minima for all
7584 builtins in each module. This forces us to consider what the
7585 valid ranges for each builtin should be, and moves the checking
7586 code out of each builtin implementation and into the builtin
7587 caller infrastructure.
7589 * m4/m4module.h (struct m4_builtin): Add argument minima and
7590 maxima.
7591 * m4/m4private.h (struct m4_token): Reflect them here too.
7592 * m4/input.c (struct input_block): ...and here.
7593 (m4_token_copy): New function for token copying.
7594 (init_macro_token): Copy them from a token to the input stack.
7595 (m4_next_token): Don't forget to initialise them for text
7596 macros.
7597 * m4/macro.c (expand_argument): Use m4_token_copy, and also
7598 check argument counts before calling the builtin handler.
7599 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
7600 (m4_symbol_macro): Likewise.
7601 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
7602 parameters. Updated all callers.
7603 (m4_builtin_define): Ditto.
7604 (m4_macro_pushdef, m4_macro_define): Ditto.
7605 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
7606 * modules/evalparse.c: Declare argument counts for defined
7607 builtins and remove explicit calls to m4_bad_argc().
7608 * modules/gnu.c: Ditto.
7609 * modules/load.c: Ditto.
7610 * modules/m4.c: Ditto.
7611 * modules/modtest.c: Ditto.
7612 * modules/mpeval.c: Ditto.
7613 * modules/perl.c: Ditto.
7614 * modules/shadow.c: Ditto.
7615 * modules/stdlib.c: Ditto.
7616 * modules/time.c: Ditto.
7617 * TODO: Updated.
7619 2001-10-10 Gary V. Vaughan <gary@gnu.org>
7621 The trace semantics now attach the trace bit to a symbol name.
7622 For as long as a traceon(`foo') is active, calls to foo will be
7623 traced regardless of intervening undefines or module unloads.
7624 Fixed the flag propogation issues differently to the fixes
7625 reverted with the last attempt at nailing down trace:
7627 * m4/m4private.h: This file is not visible outside of the m4
7628 source tree, so I removed all the `M4_' and `m4_' prefixes to save
7629 on typing. Updated all clients.
7630 (m4_token): New typedef contains the fields that need to be passed
7631 around with the low level tokeniser.
7632 (m4_token_data): Removed.
7633 (m4_symbol): Now contains the traced flag again.
7634 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
7635 the trace bit set. This change is contained entirely within this
7636 module and doesn't leak out into the callers. Updated all
7637 clients.
7638 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
7639 new fields in m4_token. Updated all clients.
7640 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
7641 that `groks_macro_args' and `blind_if_no_args' flags are retained
7642 when defn() results are passed around in m4 code. Updated all
7643 callers.
7644 (m4_builtin_define): Ditto.
7645 (m4_macro_pushdef, m4_macro_define): Ditto.
7646 * m4/input.c (struct input_block): Add a flags field to facilitate
7647 the above.
7648 (m4_push_macro): ...use it.
7649 (init_macro_token): Retrieve it.
7650 (m4_next_token): Initialise it.
7651 * m4/macro.c (expand_argument): Copy it.
7652 * m4/m4module.h: Adjust.
7653 * tests/builtins.at: Adjust the expected output of the trace
7654 tests to reflect the change in semantics.
7655 * tests/modules.at (modules: trace): Check that unloading a
7656 module which supplies a traced symbol definition doesn't lose te
7657 trace bit.
7659 2001-10-07 Gary V. Vaughan <gary@gnu.org>
7661 * modules/gnu.c (m4_macro_table): Display the timetamp when
7662 expanding __m4_version__.
7664 * configure.ac (--with-modules): Forgot a comma in the
7665 AC_HELP_STRING parameter list.
7667 2001-10-05 Gary V. Vaughan <gary@gnu.org>
7669 * bootstrap: Remove aclocal.m4t when it is no longer required.
7671 2001-10-05 Akim Demaille <akim@epita.fr>
7673 * tests/Makefile.am: Adjust for gnuprog2.
7674 * tests/m4.in: There can be a leading path.
7675 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
7676 * tests/testsuite.at: Adjust to the most recent Autotest.
7677 (AT_CHECK_M4_FILTER): Fix and rename as...
7678 (AT_TEST_M4): this.
7679 * tests/others.at: Use it.
7681 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
7682 variable in shell scripts, one uses `$'...
7684 2001-10-04 Gary V. Vaughan <gary@gnu.org>
7686 * configure.ac: `rm -f $m4_getopt_h' was lost.
7688 2001-10-04 Gary V. Vaughan <gary@gnu.org>
7690 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
7691 time. Define it for config.h in order to...
7692 * src/main.c (main): ...display the timestamp for --version.
7694 2001-10-04 Akim Demaille <akim@epita.fr>
7696 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
7697 previous builtins `regexp' and `patsubst'.
7698 (regexp, patsubst): Use them.
7699 (eregexp, epatsubst): New builtins.
7700 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
7701 (Epatsubst and Patsubst, Eregexp and Regexp): these.
7702 (Extensions): More info on REs.
7704 2001-10-04 Akim Demaille <akim@epita.fr>
7706 * modules/modtest.c (init_handler): Consistently output to stderr.
7707 (finish_handler): New.
7708 (test): The `if' is an `assert'.
7709 * tests/modules.at: Adjust.
7711 2001-10-04 Akim Demaille <akim@epita.fr>
7713 * m4/utility.c (m4_bad_argc): Detail the mismatches.
7715 2001-10-01 Akim Demaille <akim@epita.fr>
7717 * tests/generate.awk: Tag the tests with `documentation'.
7718 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
7719 Use the make the existing modtest tests more uniform, and complete
7720 the set of possibilities.
7722 2001-10-01 Akim Demaille <akim@epita.fr>
7724 * config/gmp.m4: Consult the user before using GMP: use
7725 --without-gmp.
7726 * configure.ac: Adjust.
7727 * modules/gmp.c: No protection needed as the module is not built
7728 if GMP is not used.
7730 2001-10-01 Akim Demaille <akim@epita.fr>
7732 * tests/generate.awk: Remove debugging code.
7733 (fatal): Specify the current location.
7735 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
7736 * modules/gnu.c, modules/m4.c: Use M4ARG.
7738 2001-10-01 Akim Demaille <akim@epita.fr>
7740 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
7741 (m4_regexp_compile): New.
7742 (regexp, patsubst): Use it.
7744 2001-09-30 Gary V. Vaughan <gary@gnu.org>
7746 Reinstate the memory handling improvements from the patch I just
7747 reverted. Relevant ChangeLog entries repeated here:
7749 * m4/module.c (m4_module_remove): New function that holds the core
7750 of the old m4_module_unload.
7751 (m4_module_unload): Use it.
7752 (m4_module_unload_all): When we know the modules will never be
7753 used again (i.e. on exit), free up as much module memory as
7754 possible. There are still some artifacts from resident modules
7755 living inside ltdl.c, but everything else is freed.
7756 * m4/debug.c (m4_debug_exit): Free memory allocated in
7757 m4_debug_init().
7758 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
7759 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
7760 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
7761 * m4/m4module.h: Updated prototypes.
7762 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
7763 * m4/hash.h: Updated prototypes.
7764 * src/main.c (main): Use all these new functions to clean up as
7765 much memory as possible before exit.
7767 2001-09-30 Gary V. Vaughan <gary@gnu.org>
7769 Reverted my large patch for removing the old m4_symbol
7770 structure on 2001-09-20. We are still not happy about the way
7771 trace works in conjunction with defn and undefine, and leaving
7772 the reverted patch active prevents us from moving the traced
7773 bit from the definition back to the symbol.
7775 2001-09-30 Gary V. Vaughan <gary@gnu.org>
7777 * configure.in: Moved to...
7778 * configure.ac: ...here. Added a libtool like timestamped
7779 banner, and tidied up the libltdl cruft.
7780 * config/mkstamp: Script to extract a timestamp from ChangeLog.
7781 * modules/Makefile.am (INCLTDL): Removed. This is required
7782 only when libltdl is configured in a subdirectory.
7783 * src/Makefile.am: Ditto.
7784 (LIBADD_DL): No need to add this again, libtool already knows
7785 that libm4.la depends on it.
7786 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
7787 them.
7789 * TODO: stackovf.c is basically broken.
7790 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
7792 2001-09-28 Akim Demaille <akim@epita.fr>
7794 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
7796 2001-09-27 Akim Demaille <akim@epita.fr>
7798 * tests/m4.in: Don't use short options.
7799 Simplify the stderr signature normalization.
7801 2001-09-27 Akim Demaille <akim@epita.fr>
7803 tests/m4 shall be position independent.
7805 * tests/m4.in: New.
7806 * tests/m4: Remove.
7807 * tests/testsuite.at: No args to AT_INIT.
7808 * configure.in, tests/Makefile.am: Adjust.
7810 2001-09-22 Akim Demaille <akim@epita.fr>
7812 Autotest has changed again.
7814 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
7815 (package.m4): Remove.
7816 * configure.in: Adjust to LIBADD_GMP.
7818 2001-09-21 Gary V. Vaughan <gary@gnu.org>
7820 * config/gmp.m4 (AC_ARG_WITH): Removed.
7821 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
7822 (AC_LIB_GMP): When performing a test compile against libgmp,
7823 include the header gmp.h if possible, and link against -lgmp. If
7824 they both work define USE_GMP.
7825 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
7826 (mpeval_LTX_init_func): Complain on load that there was no libgmp
7827 at compile time.
7829 2001-09-20 Gary V. Vaughan <gary@gnu.org>
7831 * m4/evalparse.c: Moved to...
7832 * modules/evalparse.c: ...here. This code is shared between
7833 modules/mpeval.c and modules/m4.c, so there is no need to pollute
7834 the libm4 API with its details. Moderately rewritten to interface
7835 into its clients more simply.
7836 * m4/eval.c: Deleted. Migrated functionality to...
7837 * modules/m4.c: ...here.
7838 (builtin_eval): Implemented in terms of the new interface style.
7839 * modules/mpeval.c (builtin_mpeval): Ditto.
7840 * m4/m4module.h: Removed references to the former m4/eval.c.
7841 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
7842 (EXTRA_libm4_la_SOURCES): Deleted.
7843 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
7844 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
7846 2001-09-20 Akim Demaille <akim@epita.fr>
7848 * config/gmp.m4 (AM_WITH_GMP): Rename as...
7849 (AC_LIB_GMP): this.
7850 By default, use gmp.
7851 Massive revamping.
7852 * configure.in: Adjust.
7853 Use Automake conditionals for USE_GMP.
7854 Always compute sizeof (long long int).
7855 This was a bug BTW, as `eval' (not `mpeval') depends on it:
7856 before, it was used _only_ if mpeval was not activated.
7857 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
7858 (mpeval_la_LIBADD): New macros.
7859 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
7860 Indent.
7861 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
7862 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
7863 WITH_GMP.
7865 2001-09-20 Akim Demaille <akim@epita.fr>
7867 * tests/Makefile.am (package.m4): New.
7868 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
7870 2001-09-20 Gary V. Vaughan <gary@gnu.org>
7872 More cleanup. After the last patch, m4_symbol holds nothing but
7873 the head of a chain of m4_token_data. So I have removed the old
7874 m4_symbol, so that m4_token_data chains are stored directly in the
7875 value cell of a hash table node. But there's more... m4_symbol
7876 was a more natural name for the symbol value cell, and now that it
7877 is gone I have renamed the former m4_token_data structure to
7878 m4_symbol. This change turned out to be a pig to get right, since
7879 the original code didn't need to modify the value cell itself,
7880 since changing the chain happened inside the m4_symbol that used
7881 to be returned -- I had to pass the address of the value cell
7882 across various function calls, incase the head value changed. I
7883 also tightened up the memory management to help me find a nasty
7884 memory corruption bug that took me all night to track down...
7886 * m4/m4private.h (struct m4_symbol): Removed.
7887 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
7888 all references.
7889 * m4/hash.c (m4_hash_iterator_value): Return the address of the
7890 value cell. Updated all callers.
7891 * m4/symtab.c: Took advantage of the simplification in the data
7892 structures to rewrite a lot of this file more simply. There is
7893 still some room for optimisation here, but we should tackle that
7894 systematically closer to the release.
7896 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
7897 revealed. This version is ahead of CVS libtool until I get chance
7898 to flush my changes.
7899 * m4/module.c (m4_module_remove): New function that holds the core
7900 of the old m4_module_unload.
7901 (m4_module_unload): Use it.
7902 (m4_module_unload_all): When we know the modules will never be
7903 used again (i.e. on exit), free up as much module memory as
7904 possible. There are still some artifacts from resident modules
7905 living inside ltdl.c, but everything else is freed.
7906 * m4/debug.c (m4_debug_exit): Free memory allocated in
7907 m4_debug_init().
7908 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
7909 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
7910 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
7911 * m4/m4module.h: Updated prototypes.
7912 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
7913 * m4/hash.h: Updated prototypes.
7914 * src/main.c (main): Use all these new functions to clean up as
7915 much memory as possible before exit.
7917 2001-09-18 Gary V. Vaughan <gary@gnu.org>
7919 The `traced' flag needs to be attached to the definition of a
7920 symbol rather than the current symbol containing the definition.
7921 Implementing this showed up some long standing post 1.4 bugs in
7922 flag propogation which I also fixed.
7924 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
7925 (struct m4_token_data): And add it back in here.
7926 * m4/input.c (init_macro_token): Propogate the traced flag
7927 correctly.
7928 * m4/macro.c (expand_argument): Ditto.
7929 * tests/builtins.at (trace2, trace3): New tests based on Akim's
7930 sadistic email ;-)
7932 2001-09-08 Gary V. Vaughan <gary@gnu.org>
7934 * m4/m4private.h (struct m4_token_data): Simplified by removing
7935 the redundant `traced' flag, and one level of structure nesting.
7936 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
7937 * m4/input.c (init_macro_token): No need to initialise removed
7938 `traced' field.
7939 * m4/macro.c (expand_argument): No need to copy it either.
7940 * m4/utility.c (m4_token_data_func_traced): Or provide an access
7941 function.
7943 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
7944 dependant on multiple symbols with the same key, so preserving
7945 relative symbol order in each bucket during resizing is no longer
7946 required. The resize function is considerably faster as a result.
7948 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
7949 s/m4_symbol_insert/m4_symbol_define/g;
7950 s/m4_builtin_insert/m4_builtin_define/g;
7951 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
7953 2001-09-08 Gary V. Vaughan <gary@gnu.org>
7955 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
7956 commits, the m4_lookup_symbol dispatch function is split into
7957 specialised functions that must be called directly.
7959 * m4/m4module.h (m4_symbol_lookup_t): Removed.
7960 * m4/symtab.c (m4_lookup_symbol): Removed.
7961 (m4_symbol_builtin, m4_symbol_macro): New functions.
7962 * m4/builtin.c (m4_builtin_define): Split into...
7963 (m4_builtin_pushdef, m4_builtin_insert): ...these.
7964 (m4_macro_define): Split into...
7965 (m4_macro_pushdef, m4_macro_insert): ...these.
7966 * src/main.c (main): Set command line macros from `-D' parameters
7967 using `m4_macro_define'.
7969 2001-09-08 Gary V. Vaughan <gary@gnu.org>
7971 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
7972 this from m4_remove_table_reference_symbols().
7973 * m4/m4module.h, m4/module.c: Updated all references.
7975 2001-09-07 Akim Demaille <akim@epita.fr>
7977 * modules/stdlib.c, modules/times.c: Misc cleanups.
7979 2001-09-07 Akim Demaille <akim@epita.fr>
7981 * configure.in: We now need Autoconf 2.52e.
7982 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
7983 and `M4_SYMBOL_DELETE'.
7984 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
7985 * src/main.c (main): Adjust.
7987 2001-09-06 Gary V. Vaughan <gary@gnu.org>
7989 Fix the obstack.h problem once and for all! At configure time we
7990 can test for a system supplied obstack.h: depending on the
7991 result, we now generate system.h with an #include of the correct
7992 header. As a bonus, I've also added a --with-included-obstack,
7993 incase the user doesn't like the system obstack for some
7994 reason... and also we can test the shipped obstack on a system
7995 that has oe of its own. We also now need to be careful to add
7996 build directories to the include search path, since the generated
7997 system.h will be in the build tree.
7999 * configure.in (AC_CONFIG_FILES): Generate system.h from
8000 system-h.in.
8001 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
8002 include the system obstack header or the copy shipped with M4.
8003 Allow the user to override configure and force the build to use
8004 the shipped version.
8005 * m4/system-h.in: New file, template for...
8006 * m4/system.h: ...this. Now deleted.
8007 * m4/m4module.h: Include system.h before everything else.
8008 * src/freeze.c: Ditto.
8009 * m4/Makefile.am (dist-hook): Remove generated system.h.
8010 (INCLUDES): Check builddir for generated headers before checking
8011 srcdir.
8012 * modules/Makefile.am (INCLUDES): Ditto.
8013 * src/Makefile.am (INCLUDES): Ditto.
8015 2001-09-05 Gary V. Vaughan <gary@gnu.org>
8017 * TODO: Remove the items that have been addressed already.
8019 2001-09-05 Akim Demaille <akim@epita.fr>
8021 * src/main.c (main): Standardize --version.
8023 2001-09-05 Akim Demaille <akim@epita.fr>
8025 * modules/format.c (format): Have a bigger `str'.
8027 2001-09-05 Akim Demaille <akim@epita.fr>
8029 Rationalize warnings, reporting the macro name as if it were a
8030 program name, and assertions.
8032 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
8033 (M4WARN): New.
8034 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
8035 (m4_symbol_delete):
8036 Use assert for internal errors.
8037 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
8038 M4WARN.
8039 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
8040 M4WARN and assert.
8041 * tests/builtins.at (pushpop): Adjust.
8043 2001-09-05 Akim Demaille <akim@epita.fr>
8045 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
8046 with pointers.
8048 2001-09-05 Akim Demaille <akim@epita.fr>
8050 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
8051 * m4/macro.c, m4/symtab.c: Adjust.
8053 2001-09-05 Akim Demaille <akim@epita.fr>
8055 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
8056 (m4_symbol_pop, m4_symbol_del): this.
8057 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
8058 (m4_symbol_popdef, m4_symbol_delete): New.
8059 (m4_lookup_symbol): Adjust.
8060 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
8062 2001-09-05 Akim Demaille <akim@epita.fr>
8064 * m4/m4module.h (m4_symbol_lookup): Rename as...
8065 (m4_symbol_lookup_t): this.
8067 2001-09-05 Akim Demaille <akim@epita.fr>
8069 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
8070 unused.
8071 * m4/symtab.c (m4_lookup_symbol): Adjust.
8073 2001-09-03 Gary V. Vaughan <gary@gnu.org>
8075 Bootstrap will now work with Libtool 1.4.1 or higher:
8076 * bootstrap: Remove stale autom4te.cache files when
8077 rebootstrapping.
8078 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
8079 libtool.m4.
8080 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
8081 libtool.m4 directly.
8082 Run libtoolize to refresh ltmain.sh.
8083 * config/ltmain.sh: Deleted.
8084 * acinclude.m4: Deleted.
8085 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
8087 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
8088 implementation for the cvs impaired libtool user.
8090 2001-09-03 Akim Demaille <akim@epita.fr>
8092 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
8093 internal errors.
8094 Avoid using `default' in switch, as it hides useful compiler
8095 warnings when a case is forgotten.
8097 2001-09-03 Akim Demaille <akim@epita.fr>
8099 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
8100 is no such thing as `WITH_MODULES'.
8102 2001-09-03 Akim Demaille <akim@epita.fr>
8104 Improve the test suite's selfcontainedness.
8106 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
8107 (Include, Undivert): Tag the other input files.
8108 * tests/generate.awk: Catch `@comment file:'.
8109 `-I $src' is no longer needed.
8110 `next' is really like `return': the rest is skipped.
8111 Adjust to `input.m4'.
8112 (fatal): New function.
8113 * tests/foo, tests/incl.m4: Remove.
8115 2001-09-01 Gary V. Vaughan <gary@gnu.org>
8117 The shadowing mechanism and, infact, the whole symbol table
8118 implementation was creaking under the weight of the features piled
8119 on top of it. We now have a separate hash table module which will
8120 dynamically resize to keep symbol density withing good performace
8121 limits, and a new symtab module layered above it. Symbol lookups
8122 are now marginally more efficient (since the shadowed flag is no
8123 longer required) and symbol removal, such as on module unload, is
8124 considerably faster due to a reorganisation of the data structures
8125 used in symtab.c.
8127 * src/main.c (main): Don't mention `-H'.
8128 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
8129 effect.
8130 * NEWS: Updated.
8131 * m4/hash.c: New generalised dynamic hash table data structure
8132 management module.
8133 * m4/hash.h: Public interface.
8134 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
8135 (libm4_la_SOURCES): Add hash.c.
8136 * m4/symtab.c: More or less rewritten from scratch, within the
8137 bounds of the previous API.
8138 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
8139 call. Updated all callers.
8140 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
8141 declarations to reflect API changes.
8142 (M4INIT): Generate a declaration too, to avoid the warning with
8143 --enable-debug builds.
8144 (M4FINISH): Ditto.
8145 (HASHMAX): Removed.
8146 * m4/utility.c (hash_table_size): Removed.
8147 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
8148 names, which are then looked up by builtin_dumpdef() as necessary.
8149 This implies a small speedup in builtin_symbols(), which discarded
8150 all of the symbol info under the old call.
8151 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
8152 shadowing is implicit in respect to the new data structures.
8153 symbol names are no longer duplicated here, they are stored in the
8154 key field of the hash table.
8155 Moved macro_args and blind_no_args...
8156 (m4_token_data): ...to here.
8157 m4/macro.c (expand_macro): Added a name argument since the symbol
8158 name is no longer copied into each struct m4_symbol. Modified all
8159 callers.
8160 (collect_arguments): Ditto.
8161 * modules/m4.c (set_trace): Ditto.
8162 * modules/gnu.c (builtin_symbols): Updated.
8163 * src/freeze.c (produce_symbol_dump): Much improved in light of
8164 the improved symbol table layout.
8166 2001-09-01 Gary V. Vaughan <gary@gnu.org>
8168 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
8169 to M4_SYMBOL_NEXT.
8170 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
8171 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
8172 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
8173 SYMBOL_HANDLE): Ditto.
8174 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
8175 modules/gnu.c, modules/m4.c, src/freeze.c,
8176 src/main.c: Updated all references.
8178 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
8179 Automake 1.5 chokes on dynamic source file lists, Besides, it is
8180 already listed in m4_LDADD... how did that ever used to work?
8181 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
8182 link.
8183 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
8184 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
8186 * tests/m4: Don't call the m4 wrapper script with libtool, it
8187 works fine all by itself.
8189 2001-08-30 Gary V. Vaughan <gary@gnu.org>
8191 The experimental `changeword' feature never took off, and has
8192 no obvious advantages over `changesyntax' to compensate the
8193 enormous speed penalty it carries:
8194 * configure.in (ENABLE_CHANGEWORD): Removed.
8195 * m4/m4module.h (m4_set_word_regexp): Removed.
8196 * m4/m4private.h (m4_token_data): Removed original_text field.
8197 * m4/utility.c (m4_token_data_orig_text): Removed.
8198 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
8199 * m4/macro.c: Ditto.
8200 * src/main.c: Ditto.
8201 * modules/Makefile.am (changeword.la): Removed.
8202 * modules/changeword.c: File removed.
8203 * doc/m4.texinfo: References to changeword and --word-regexp
8204 removed.
8205 * po/POTFILES.in: modules/changeword.c removed.
8206 * tests/atlocal.in (ENABLE_CHANGEWORD): Removed.
8207 * tests/builtins.at (changeword): Test removed.
8209 2001-08-30 Akim Demaille <akim@epita.fr>
8211 * bootstrap.sh: Create aclocal.m4 instead of modifying it.
8212 This also help having a single list of m4 files: in
8213 config/Makefile.am.
8214 * config/Makefile.am (STANDARD_MACROS): Rename as...
8215 (ACLOCAL_MACROS): this.
8216 (list-standard-macros): Remove.
8217 (spy): New.
8219 2001-08-29 Gary V. Vaughan <gary@gnu.org>
8221 In an attempt to moderate my egomania...
8222 * tests/modules.at: Remove attributions.
8224 * tests/generate.awk: When making substitutions to "@&t@", either
8225 "&" or "\&" in the substitution string argument to gsub refer back
8226 to the matched text. "@\\&t@" seems to work though, Tests 43 and
8227 67 now pass for me.
8229 2001-08-29 Akim Demaille <akim@epita.fr>
8231 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)
8232 (include, indir, multiquotes, patsubst, pushdef/popdef, regexp)
8233 (sync-lines, trace, translit, undivert, wrap): Move to...
8234 * tests/builtins.at: this new file.
8235 * tests/others.at (Discard comments, import-environment): Move to...
8236 * tests/options.at: this new file.
8238 2001-08-29 Akim Demaille <akim@epita.fr>
8240 * tests/others.at (Freezing modules)
8241 (--module-directory: absolute path, modpath2, modpath3)
8242 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
8243 * tests/modules.at: here, new file.
8244 * tests/others.at, tests/generate.awk: Add a banner.
8245 * tests/testsuite.at: Adjust.
8246 (AT_CHECK_M4_FILTER): New, but unused.
8248 2001-08-29 Akim Demaille <akim@epita.fr>
8250 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
8251 handle that.
8252 * tests/others.at (wrap): Inline wrap.m4.
8253 (shadow): Inline shadow.m4.
8254 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
8255 * tests/m4: Simplify.
8257 2001-08-29 Akim Demaille <akim@epita.fr>
8259 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
8260 --language.
8262 2001-08-29 Akim Demaille <akim@epita.fr>
8264 * tests/generate.awk (normalize): s/@__@/@&t@/.
8266 2001-08-28 Akim Demaille <akim@epita.fr>
8268 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.
8270 2001-08-28 Gary V. Vaughan <gary@gnu.org>
8272 * bootstrap (generate.awk): Generate test cases with new script.
8274 2001-08-27 Akim Demaille <akim@epita.fr>
8276 * tests/Makefile.am (installcheck-local): Don't use
8277 `dc_install_base' which is not visible here, but `exec_prefix'
8278 which is clearly the RT anyway.
8279 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
8280 related to testing a now installed m4.
8281 * tests/m4: Do it here.
8283 2001-08-27 Akim Demaille <akim@epita.fr>
8285 * tests/others.at (indir): Formatting change.
8287 2001-08-27 Akim Demaille <akim@epita.fr>
8289 * tests/Makefile.am (installcheck-local): New.
8290 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
8291 the test suite.
8292 Prefer options over envvars.
8293 * src/main.c (main): First bug caught by the test suite (yeah!):
8294 --batch lacked a `break' which resulted in an accidental
8295 invocation of --discard-comments.
8297 2001-08-27 Akim Demaille <akim@epita.fr>
8299 * tests/others.at (capitalize, changeword, comments, ddivert)
8300 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
8301 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
8302 (sysv-args, trace, translit, undivert): Don't rely on files in
8303 examples/: AT_DATA them.
8305 2001-08-27 Akim Demaille <akim@epita.fr>
8307 Let the test suite use a wrapper around the not installed m4 to
8308 pretend it is (installed).
8310 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
8311 such a way that m4 does not process them.
8312 * configure.in: The package name seems to be `m4', not `M4'.
8313 * tests/m4: New.
8314 * tests/atlocal.in (at_package, M4): Remove.
8315 * tests/testsuite.at, tests/others.at: Use m4, not $M4.
8317 2001-08-27 Akim Demaille <akim@epita.fr>
8319 * tests/Makefile.am (CLEANFILES): Remove.
8320 (DISTCLEANFILES, clean-local): New.
8321 * examples/mktests.sh: Remove.
8323 2001-08-27 Akim Demaille <akim@epita.fr>
8325 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
8326 Don't use aclocal: it's written by hand.
8327 * aclocal.m4: m4_include all the files instead of being built by
8328 aclocal.
8329 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
8330 until it reads the traces by itself.
8331 * configure.in: Require Autoconf 2.42c as we are now using
8332 AC_CONFIG_TESTDIR instead of AT_CONFIG.
8333 Catch unexpanded `jm_' macros.
8334 * config/atconfig.m4: Remove.
8335 * config/error.m4: new.
8336 * config/Makefile.am: Ship the files included by aclocal.m4.
8337 * tests/Makefile.am (TESTSUITE_SOURCES): Rename as...
8338 (TESTSUITE_AT): this, to please Automake.
8339 (TESTSUITE): This target uses autotest/autotest.m4, not
8340 autotest/general.m4.
8341 * tests/testsuite.at: Prereq Autotest 2.52c.
8342 * examples/Makefile.am (pkgdata_DATA): Rename as...
8343 (dist_pkgdata_DATA): this.
8344 * doc/Makefile.am (man_MANS): Rename as...
8345 (dist_man_mans): this.
8347 2001-08-20 Gary V. Vaughan <gary@gnu.org>
8349 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
8350 Robert Collins, building on Cygwin no longer requires Windows
8351 import and export symbol decorations.
8352 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.
8353 * m4/error.h (M4_SCOPE) [cygwin*]: Ditto.
8354 * m4/debug.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
8355 * m4/error.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
8356 * m4/input.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.

8358 * m4/output.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
8359 * m4/utilty.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
8360 * m4/xmalloc.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
8361 * configure.in (LIBM4_DLL_IMPORT) [cygwin*]: Don't set this
8362 anymore.
8363 * src/Makefile.am (AM_CPPFLAGS) [cygwin*]: Don't use it either!
8364 * modules/Makefile.am (AM_CPPFLAGS) [cygwin*]: Ditto.
8366 2001-08-20 Gary V. Vaughan <gary@gnu.org>
8368 Ansify the source. Previously we had a mix, where my code was
8369 in a K&R compatible style, and the preexisting code was in ANSI
8370 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
8371 and now the code base is much cleaner.
8373 * m4/system.h: Remove M4_PARAMS macro and all users. Remove
8374 VOID macro and all users.

8393 2001-08-20 Akim Demaille <akim@epita.fr>
8395 * config/atconfig.m4: s/EOF/ATEOF/, so that configure can be
8396 generated with stock 2.52.

8404 * tests/atlocal.in: New.
8405 * tests/generate.awk: For the time being, the empty quadrigraph is
8406 `@__@'.
8407 * tests/others.at (changeword, gmp): Check the configuration
8408 variable against `yes'.
8409 * tests/testsuite.at (dnl): Allow it, as it's used all over the
8410 place.
8412 2001-08-20 Akim Demaille <akim@epita.fr>
8414 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
8415 * modules/m4.c (undivert): Disable the possibility of undiverting
8416 several files at once: it is not documented, it is inconsistent
8417 with the other macros, it can be straightforwardly mocked by
8418 several invocations, and most importantly, it prevents the
8419 possibility of other kinds of extension.
8420 Use `m4_numeric_arg'.
8422 2001-08-20 Akim Demaille <akim@epita.fr>
8424 * examples/include.m4: Typo.
8425 * tests/generate.awk: Really add it.

8430 2001-08-20 Akim Demaille <akim@epita.fr>
8432 Use sprintf, not ecft and friends since it is standard, portable,
8433 simplifies the code, and since the latter is even deprecated
8434 according to the GNU libc documentation.
8436 * modules/format.c: Drop evct support.
8438 2001-08-19 Gary V. Vaughan <gary@gnu.org>
8440 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Cleaned up. Don't test
8441 for `-pipe' here...
8442 * configure.in: ...do it here instead.
8444 * c-boxes.el: Deleted.
8445 * m4/builtin.c: Reformat box comments to be closer to GNU
8446 standards.

8477 * tests/testsuite.at (AT_CHECK_M4): Normalize the path of input
8478 files in error messages.
8480 2001-08-17 Akim Demaille <akim@epita.fr>

8491 (generate.at): Install a temporary hack until the actual
8492 generate.awk is added to the repository.
8493 * tests/atconfig.in: New.
8495 2001-08-17 Akim Demaille <akim@epita.fr>

8545 (sync-lines): this.
8546 (modfreeze, modpath1, modpath2, modpath3, modpath4, modtest, shadow)
8547 (unload.test): Keep their authorship.
8548 (discard-comments, gmp, import-environment, modfreeze)

8563 2001-08-17 Akim Demaille <akim@epita.fr>

8580 2001-08-17 Akim Demaille <akim@epita.fr>
8582 Drop Autoconf 2.13 compatibility.
8584 * configure.in (changeword): No need to undefine it, as anyway if
8585 it's defined, M4sugar moved it as m4_changeword.
8586 And anyway, proper quotation is enough.
8587 (m4_pattern_allow): As it exists in 2.50, just use it.
8588 (AC_OUTPUT): Split in AC_CONFIG_FILES and AC_CONFIG_COMMANDS.
8589 Don't handle Gettext's duties, let it handle them.

8600 * doc/Makefile.am: Add `TAGS' support.
8601 (MAINTAINERCLEANFILES): Remove texinfo.tex and mdate-sh which are
8602 in `config/' now.
8603 * config/Makefile.am (MAINTAINERCLEANFILES): New.
8605 2001-08-17 Akim Demaille <akim@epita.fr>

8622 2001-08-16 Gary V. Vaughan <gary@gnu.org>

8627 * m4/ltdl.c: Updated from master copy.
8628 * m4/module.c: Reimplemented to take advantage of advances in

8637 (m4_modules): No longer required.
8638 (m4_module_init_t, m4_module_finish_t): POSIX namespace
8639 violations, renamed to...
8640 (m4_module_init_func, m4_module_finish_func): ...these,
8641 respectively.
8642 (M4INIT_HANDLER): Clean way to declare init functions in modules.
8643 (M4FINISH_HANDLER): And similarly for finish functions.
8644 * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER
8645 -- Add indirection to the CONC macro so that arguments are
8646 correctly expanded.
8647 * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
8648 * modules/shadow.c (m4_init_module): Ditto.
8649 Due to new init function semantics, be careful to perform the
8650 initialisation only on first load.
8651 * modules/perl.c (m4_init_module): Ditto. And Ditto.
8652 (m4_finish_module): Replaced with M4FINISH_HANDLER.
8653 Due to new finish function semantics, be careful to perform the
8654 finalisation only on first load.
8655 * m4/m4private.h (m4_module): Removed in favour of...
8656 (m4_module_data): ...structure without all the wrapper fields.
8657 Instances of this new structure are stored associated lt_dlhandles
8658 with lt_dlcaller_data_set().

8660 instead of the old module argument.
8661 (m4_builtin_table_install): Ditto.
8662 * modules/load.c (m4_resident_module): Removed. This is no
8663 longer implemented as a magic symbol...
8664 * modules/m4.c (m4_resident_module): Ditto.
8665 * modules/load.c (M4INIT_HANDLER): ...the module init function now
8666 uses the ltdl api to make the module resident.

8668 * modules/load.c (builtin_modules): Traverse the loaded module
8669 list with lt_dlhandle_next.

8671 module loader.

8678 (libm4_la_SOURCES): Delete list.c reference.

8680 eliminates many of the searches to find the handle associated with
8681 various tokens that are passed between functions.
8682 (struct m4_symbol): Removed the module field. The
8683 module association does not belong with the symbol...
8684 * m4/input.c (struct m4_builtin): ...it belongs with the builtin
8685 that the module implementation code is from. Added a handle
8686 field.
8687 (m4_push_macro): Add a `handle' argument. Changed all callers.
8688 (init_macro_token): Set the `handle' field for the
8689 m4_token_data.
8690 * m4/macro.c (expand_argument): Copy the new handle field during
8691 reassignment.

8696 2001-08-15 Akim Demaille <akim@epita.fr>
8698 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Be sure `m4/' exists
8699 when creating `m4/obstack.h'.
8700 * tests/Makefile.am (TESTS_ENVIRONMENT): Pass top_srcdir and
8701 top_builddir.
8702 * tests/defs: Make them absolute.
8703 (CDPATH) Neutralize.
8704 * tests/gethem: Use them.
8706 2001-08-14 Gary V. Vaughan <gary@gnu.org>
8708 * config/ltmain.sh: Doh! Import again for a quoting fix that

8712 and shipped version based on configure tests.
8713 * src/freeze.c (obstack.h): Ditto.

8719 them to AC_INIT and AM_INIT_AUTOMAKE.
8720 * Makefile.am (AUTOMAKE_OPTIONS): Remove `gnits' which would
8721 disallow MY_NAME and MY_VERSION arguments to AM_INIT_AUTOMAKE.
8722 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Don't choke on
8723 shell variable m4_cv_func_obstack_h.
8724 * tests/defs (M4): Be more careful about relative path to libtool
8725 script and m4 binary by using $srcdir.
8727 * src/main.c (main): Use lt_dlinsertsearchdir to prepend -M
8728 optargs to the existing libltdl search path.
8729 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.
8730 * m4/ltdl.c: Updated.
8731 * m4/ltdl.h: Ditto.
8732 * config/ltmain.sh: Ditto.
8734 2001-08-11 Gary V. Vaughan <gary@gnu.org>
8736 * src/main.c (main): Add `-b' (for `batch') mode switch to force
8737 interactive mode off.
8739 2001-08-10 Akim Demaille <akim@epita.fr>
8741 * configure.in: Require Autoconf 2.52.
8742 (AC_ARG_PROGRAM): Remove, handled by Automake.

8744 (m4_getopt_h): this.
8745 Allow the tokens `m4_cv_*', `m4_top_srcdir', and `m4_getopt_h'.
8746 Undefine `changeword' only if defined.
8747 * config/gnu-obstack.m4: Require Autoconf 2.52.
8748 (M4_AC_FUNC_OBSTACK): Rename `m4_obstack' and `m4_obstack_h'.

8759 string).
8761 2001-08-07 Akim Demaille <akim@epita.fr>
8763 Improve `make distcheck'.
8765 * configure.in: Be sure to be able to run `mkconfig.sh' when src
8766 != build.

8768 * doc/m4.texinfo (Include): Add missing blank.

8796 * modules/format.c (format): Formatting for %f was not
8797 interpreting the position of the decimal point correctly for
8798 whole numbers.
8800 2000-12-01 Gary V. Vaughan <gary@gnu.org>
8802 * TODO: Removed m4exit bug.
8803 * modules/load.c (m4_resident_module): Make this module resident.
8804 * module/m4.c (m4_resident_module): Ditto.
8805 * m4/modules.c (m4_module_load): Use new ltdl resident modules
8806 feature to mark modules as resident if they export

8829 2000-11-29 Gary V. Vaughan <gary@gnu.org>
8831 Consolidate the myriad of dispersed test scripts into the
8832 tests subdirectory. I think I now have all the file where I
8833 want them, so there shouldn't be anymore upheaval =)O|
8834 Honest!

8853 of the tests removed below.
8854 * examples/Makefile.am, modules/Makefile.am: Updated to
8855 reflect removed tests.

8870 modules/modpath3.test, modules/modpath4.test,

8872 modules/unfrozen.m4, modules/unload.test: Removed.
8874 Move the implementation of GMP support for the mpeval() builtin
8875 into a loadable module that depends on libgmp. mpeval() and
8876 eval() share a common parser, now in m4/evalparser.c; the code
8877 in m4/numb.c and m4/numb.h is now physically split between
8878 m4/eval.c (the eval() backend) and modules/mpeval.c (the
8879 mpeval() backend), rather than being differentiated by cpp
8880 macros and multiple inclusion. The mpeval module is always
8881 built but will generate an diagnostic if it is used from an
8882 installation that didn't link in the gmp library.
8883 * modules/Makefile.am: build and install the new mpeval module.
8884 * modules/mpeval.c: Now contains the former parts of m4/numb.c
8885 and m4/numb.h that are required for gmp support in mpeval().
8886 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
8887 * m4/evalmp.c: Removed.
8888 * m4/m4module.h: Removed conditional prototype for
8889 m4_mp_evaluate().
8890 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
8891 and m4/numb.h that do not rely on gmp.
8892 * m4/evalparse.c: New file, contains the shared parts of the
8893 eval() and evalmp() parser implementations, and is no longer
8894 unencumbered by cpp magic to uncover the right parts.
8895 * m4/numb.h: Removed. It's former contents are split between
8896 m4/eval.c and modules/mpeval.c.
8897 * m4/numb.c: ditto.
8899 * tests/other-tests/changeword.test: New test. Rudimentary
8900 testing of changeword builtin runs only if --wnable-changeword
8901 was used at configure time.
8902 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
8903 alternation correctly. Split into two expressions to compensate.
8904 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
8905 * modules/Makefile.am: Build changeword module.
8906 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
8907 only when --enable-changeword was passed to configure.
8908 (builtin_changeword): If --enable-changeword was not used, then
8909 report that changeword() builtin has no support in m4 binary.
8911 2000-11-28 Gary V. Vaughan <gary@gnu.org>
8913 * src/main.c (main): Fixed a particularly nasty bug is
8914 user_search_path setting -- the -M flag processing must be
8915 extremely careful with search path ordering, or else the default
8916 installed module directory (possibly containing modules from a
8917 previous release) is placed earlier in the search path than any -M
8918 arguments (which are relied upon to load uninstalled modules with
8919 most of the tests in the regresion suite).
8921 * modules/load.c (builtin_load): Nasty hack to prevent adding
8922 symbols to symtab again if a module is loaded more than once.
8923 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
8925 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
8926 possible NULL pointer dereference.
8928 * m4/module.c (m4_module_find_by_modname): Renamed from
8929 m4_module_modname_find. Fixed all references.
8930 (m4_module_find_by_builtin): New function.
8932 * modules/modfreeze.test: load the `load' module with each
8933 invocation.
8934 * src/freeze.c (produce_frozen_state): Simplified in light of
8935 module field in m4_symbol. Allow a third argument for text macros
8936 to name the originating module.
8937 (reload_frozen_state): ditto.
8938 * m4/m4module.h: Fixup prototypes.
8939 * m4/builtin.h (m4_builtin_define): Add a module argument so
8940 that symbols can be registered against the defining module.
8941 (m4_macro_define): ditto.
8942 * m4/m4private.h (m4_symbol): Make the module field const to save
8943 on casting in the rest of the code.
8944 (SYMBOL_MODULE): New macro.
8946 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
8947 symbol reference maintenance bugs when removing a symbol from the
8948 symtab.
8950 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
8952 2000-11-27 Gary V. Vaughan <gary@gnu.org>
8954 * configure.in (m4_cv_func_obstack): A better check for whether
8955 libc has an obstack implementation.
8956 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
8958 * configure.in (--with-modules): Changed semantics. This
8959 option is now used to list modules to be preopened.
8960 * src/m4.h: #include "ltdl.h" unconditionally.
8961 * src/main.c: Removed all dependencies on WITH_MODULES.
8962 * src/freeze.c: ditto.
8963 * modules/Makefile.am: ditto.
8964 * m4/m4.c (builtin_m4exit): ditto.
8965 * modules/modpath1.test: ditto.
8966 * modules/modpath2.test: ditto.
8967 * modules/modpath3.test: ditto.
8968 * modules/modpath4.test: ditto.
8969 * modules/modtest.test: ditto.
8970 * modules/shadow.test: ditto.
8971 * modules/unload.test: ditto.
8973 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
8974 comes up on demand in LTLIBOBJS now.
8975 * configure.in (getopt_long): Creating and relying on a link for
8976 getopt.h on hosts with no getopt_long() of thier own works
8977 correctly now. This is necessary so that callers of getopt_long()
8978 can simply `#include <getopt.h>': the naive way of doing this
8979 would end up using our own getopt.h and the installed
8980 getopt_long(), which is asking for trouble!
8981 (obstack_init): A similar argument applies to obstack.h and
8982 obstack_init().
8984 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
8985 On Solaris-2.5 (at least) the native dlopen implementation
8986 gets confused about m4.o when looking for module "m4". This
8987 version always looks for .la an .$lib_ext suffixed names first
8988 to work around the problem. Sigh.
8990 * po/POTFILES.in: Take account of these file movements.
8991 * src/Makefile.am (m4_SOURCES): removed eval.c.
8992 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
8993 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
8994 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
8995 * modules/m4.c (builtin_eval): Use m4_evaluate().
8996 * m4/eval.c: Moved here from src/eval.c to facilitate
8997 implementation of eval() builtin as part of the `m4' loadable
8998 module.
8999 (m4_evaluate): renamed from evaluate for namespace cleanliness.
9000 * m4/numb.c: Moved here from src/numb.c, since it is #included
9001 into eval.c at compile time.
9002 * m4/m4module.h (m4_evaluate): Added prototype.
9003 * src/m4.h (evaluate): Removed prototype.
9005 2000-11-25 Gary V. Vaughan <gary@gnu.org>
9007 * modules/perl.c (builtin_perleval): Use PL_na for
9008 compatibility with perl-5.6.
9010 * src/main.c (main): It is now safe to
9011 ``m4_module_install("m4")'', without tripping over the m4
9012 binary itself!
9013 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
9014 versions having fixed the insidious module search order bug.
9016 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
9017 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
9019 * configure.in: Figure out whether to use the installed
9020 getopt.h or the supplied one.
9021 * src/Makefile.am: ditto.
9023 * po/POTFILES.in: List files in their new positions.
9025 * config/ltmain.sh: This needs to be checked in to match the
9026 libtool macros copied to acinclude.m4 (until a released
9027 libtool copes with m4's needs).
9028 * bootstrap: Run gettextize.
9030 2000-11-24 Gary V. Vaughan <gary@gnu.org>

9076 * src/main.c (main): Load the traditional module if m4 was
9077 started in `no_gnu_extensions' mode.
9078 * modules/traditional.c: New file implementing the ``unix'' macro,
9079 required when m4 is executed in traditional mode, as a loadable
9080 module.

9092 the migration of all builtin implementations to loadable modules.
9093 * m4/macro.c: Moved this file here from the src directory,
9094 renaming all exported symbols to use the prefix ``m4_''.
9095 * m4/builtin.c: ditto.

9097 * m4/symtab.c: ditto.

9104 directory to facilitate builtin migration.
9106 2000-08-12 Gary V. Vaughan <gary@gnu.org>
9108 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
9109 error message, to make translators' jobs a little easier.

9138 Removed `Prev', `Next' and `Up' fields of all @nodes now that
9139 makeinfo calculates them for us, and to make any future
9140 reorganisation easier.
9141 (Frozen files): Document format version 2.
9142 `V' now takes argument `2'.
9143 `F' can take a single argument if symbol and builtin names
9144 are the same, or 3 arguments if the builtin is from a module.
9145 New `S' specification for saving syntax table contents.
9146 New `M' specification for saving loaded module names.

9255 emulating calloc with malloc.

9287 * src/builtin.c: Much improved macro definition style.
9288 * src/m4private.h: Internal structures for m4_builtin and
9289 m4_macro instances. These are not exposed to module writers.

9300 odule defines an identical name.

9302 table entries which refer to a given builtin table.

9308 * acm4/modules.m4: deleted
9309 * bootstrap: don't libtoolize libltdl!
9310 * configure.in: AC_SUBST INCLTDL and LIBLTDL, -with-modules flag:
9311 if set, enable WITH_MODULES and add modules to DLPREOPEN
9312 * examples/misc.test: redirect standard output
9313 * lib/Makefile.am: don't use DLLDFLAGS
9314 * lib/m4module.c: include necessary headers to silence GCC -Wall

9325 LTDL_SET_PRELOADED_SYMBOLS
9326 * src/module.c: libltdl's memory management must be initialized
9327 before calling lt_dlinit!, fix warnings
9329 2000-01-18 Gary V. Vaughan <gary@gnu.org>
9331 * README: Caveat about nls not supported by dll architecture on
9332 Windows.
9334 * TODO (MODULE SPECIFIC ISSUES): more ideas for the future.
9336 * tests/Makefile.am (stamp-TESTS): now works with VPATH.
9337 * src/Makefile.am (m4_LDADD): use $(builddir) for VPATH.
9338 * modules/Makefile.am (LIBS): ditto.
9339 (INCLUDES): search $(top_srcdir) (for eg. <m4/error.h>) and then
9340 $(top_srcdir)/m4 (for only <m4module.h>).
9341 * modules/shadow.test: fixed for VPATH.
9342 * modules/modtest.test: ditto.
9343 * modules/modpath4.test: ditto.
9344 * modules/modpath3.test: ditto.

9349 * modules/Makefile.am (TESTS): Removed time.test.
9351 * configure.in: Use $3 of AC_DEFINE so that we can,,,
9352 * acconfig.h: Remove everything except the gettext parameters.
9353 * acm4/gmp.m4: Add a serial number, and take advantage of $3 of
9354 AC_DEFINE.

9356 * acm4/modules.m4: Remove code which duplicates ltdl.m4 and
9357 increment serial number.
9359 * Makefile.am (SUBDIRS): Moved @MODULES_DIR@ to compile before
9360 src dir and immediately after libm4 is built for confidence that
9361 it doesn't rely on the src directory.
9362 (SUBDIRS): Moved doc dir to the end since helptoman.pl and
9363 makeinfo stop the build on cygwin (because they don't work).
9365 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
9367 * m4/m4private.h: ...is not a public header, so moved to src.
9368 Add `#include <config.h>', `#define _COMPILING_M4' and
9369 `#include "m4.h".
9370 * m4/Makefile.am (noinst_HEADERS): remove m4private.h.
9371 * src/Makefile.am (noinst_HEADERS): add m4private.h.
9372 * src/builtin.c: `#include "m4private.h"' now takes care of the

9391 (INCLUDES): Look first in $(top_srcdir) (for eg. <m4/error.h>),
9392 and then in $(top_srcdir)/lib (for eg. "m4private.h").
9393 * src/Makefile.am (m4_LDADD): replace libi/libm4.la with
9394 m4/libm4.la.
9395 * m4/m4error.h: Renamed error.h, for installation to
9396 $prefix/include/m4..

9406 * configure.in (AC_OUTPUT): reference m4/Makefile.in.
9407 * acm4/regex.m4: Point to m4/regex.c.
9409 * examples/foreach.m4: Sanitise quoting.
9410 * examples/foreach.test: New torture test.
9411 From Akim Demaille <akim@epita.fr>
9413 2000-01-17 Gary V. Vaughan <gary@gnu.org>
9415 * src/ltdl.c: Use access() to abort doomed module load attempts
9416 if module file does not exist.
9418 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
9419 getopt1.o will already be used if appropriate, so I moved getopt.c
9420 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
9422 * modules/modpath1.test: Use correct filename in header line.
9423 * modules/modpath2.test: ditto.
9424 * modules/modpath3.test: ditto.
9425 * modules/modpath4.test: ditto.
9427 Without these changes lt_dlopen("test") attempts to
9428 LoadLibrary("/bin/test") on Windows, which although harmless
9429 generates a spurious error message which spoils most of the tests:
9430 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
9431 (TESTS): s/test.test /modtest.test /
9432 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /
9433 (test_la_SOURCES, test_la_LDFLAGS): renamed to use modtest.
9434 * modules/modpath1.test: s/test.m4 /modtest.m4 /
9435 * modules/modpath2.test: ditto.
9436 * modules/modpath4.test: ditto.
9437 * modules/modpath3.test: s/-m test /-m modtest /
9438 * modules/shadow.m4: use {un,}loadmodule(`modtest').
9440 2000-01-16 Gary V. Vaughan <gary@gnu.org>
9442 * src/ltdl.c (find_file): Updated to new version with fixed memory
9443 allocation bug in `next'.
9444 * src/ltdl.h: updated to match.
9446 * modules/Makefile.am: Cleaned up and reordered.
9448 2000-01-16 René Seindal <rene@seindal.dk>
9450 * modules/Makefile.am (TESTS): New tests for the module system.
9452 * modules/*.test: New files.
9454 * src/m4.c (main): Added call to module_init().
9455 Treats -M and -m as the arguments -D -U and -t, ie deferred.
9457 * src/m4.h: Added declaration of module_init().
9459 * src/module.c (module_init): No longer static
9461 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
9462 Added to shut up automake about non standard libtool library
9463 names.
9465 * src/module.c: Disabled DEBUG by default.
9467 * modules/README: Changed example from unload.m4 to shadow.m4
9469 * modules/shadow.m4: Renamed from unload.m4
9471 * modules/Makefile.am (EXTRA_DIST): Removed unload.m4.
9473 * src/m4.c (main): Functionality for -m and -M were reversed.
9474 Fixed.
9476 2000-01-12 Gary V. Vaughan <gary@gnu.org>
9478 * doc/help2man.pl: updated to version 1.020.
9480 * lib/COPYING.LIB: updated to version 2.1.
9482 * lib/m4module.h: restructure the M4_SCOPE code to work when
9483 creating a dll which links with libm4.la and both DLL_EXPORT
9484 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
9485 both defined.
9487 2000-01-11 Gary V. Vaughan <gary@gnu.org>
9489 Merged the following changes from my tree:
9491 1999-06-15 Gary V. Vaughan <gary@gnu.org>
9493 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
9494 ported to compile shared libs.
9496 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
9497 use `__declspec(dllimport)' when linking libm4.la on win32.
9498 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
9500 * configure.in (M4OBJS): Discover whether we need the shipped
9501 implementation of getopt_long.
9502 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
9503 main binary here, as opposed to the module library in lib/libm4.la.
9505 1999-06-14 Gary V. Vaughan <gary@gnu.org>
9507 * modules/README: Updated to describe the improved libltdl based
9508 module scheme.
9509 * README (cygwin): Added some compilation notes for building m4
9510 correctly under cygwin.
9511 * TODO: Cleaned out the entries for the module system since they
9512 are now implemented.
9514 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
9515 all instances of __P with M4_PARAMS.
9517 * lib/getdate.h: removed unreferenced file.
9519 * lib/m4private.h: New file to define the private interface to the
9520 token_data struct, which must be shared between m4module.c, and
9521 builtin.c but not exported to modules built from the installed
9522 m4module.h since it's size changes depending on compile time
9523 options.
9525 * src/m4.h: Lots of stuff moved to lib/m4module.h.
9527 * lib/m4module.h: New file to define the interface available when
9528 compiling m4 modules.
9529 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
9530 necessary for module compilation into this new file.
9532 * lib/Makefile.am (include_HEADERS): install headers (renamed to
9533 avoid nameclash with other system headers) necessary for compiling
9534 modules.
9535 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
9536 so that modules can include the (renamed) installed headers and
9537 be guaranteed a matching implementation.
9538 * lib/m4error.h: renamed from error.h.
9539 * lib/m4obstack.h: renamed from obstack.h.
9540 * lib/m4regex.h: renamed from regex.h.
9541 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
9542 implementation, simply include the shipped version
9543 unconditionally, otherwise it is hard for a module to know
9544 whether the m4obstack.h header it is using matches the
9545 implementation it ends up linking against.
9546 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
9547 the same reason.
9549 1999-05-18 Gary V. Vaughan <gary@gnu.org>
9551 * examples/misc.test: Don't run this test on machines which don't
9552 have a root user in /etc/passwd (e.g. cygwin).
9554 * tests/get-them (/^@example$/): Error messages might have a
9555 ``.exe'' suffix to the program name, or else use the libtool
9556 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
9557 of these cases are now catered for when comparing error messages
9558 in generated tests.
9559 * tests/other-tests/*.test: ditto.
9560 * examples/*.test: ditto.
9562 * tests/defs (M4): use libtool execute mode.
9563 * examples/defs (M4): ditto.
9565 * tests/get-them (END): explicitly close any open file.
9566 (printthem): In a regular expression, '{' is the start of a repeat
9567 count! Use `[{]' for a literal open brace.
9568 (/^@node /): Don't use substr on a string shorter than the trim
9569 length.
9571 1999-05-17 Gary V. Vaughan <gary@gnu.org>
9573 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
9574 substituted.
9575 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
9577 2000-01-10 Andreas Schwab <schwab@suse.de>
9579 * tests/other-tests/gmp.test: Find config.sh in build directory.
9581 * configure.in: Find tests/mkconfig.sh in $srcdir.
9583 * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in
9584 <signal.h> (for SUS2 compliant systems).
9586 * src/stackovf.c: Check for HAVE_SIGINFO_T in addition to
9587 HAVE_SIGINFO_H.
9589 2000-01-10 René Seindal <rene@seindal.dk>
9591 * Prerelease 1.4o.
9593 * TODO, NEWS: Cleaned up and updated.
9595 * src/m4.c (main): New variable exit_status for exit status in
9596 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
9597 file cannot be read instead of EXIT_SUCCESS.
9599 * src/builtin.c (m4_indir): Changed error message to help
9600 translators (from Akim Demaille <demaille@inf.enst.fr>).
9602 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
9603 Cygnus.
9605 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
9606 from glic 2.1.2.
9608 * src/input.c (match_input): Reordering of code, to avoid multiple
9609 calls to push_string_init() from obstack_grow(), which can happen
9610 with some compilers (found and fixed by James Bonfield
9611 <jkb@mrc-lmb.cam.ac.uk>).
9613 * src/stackovf.c: Added prototypes for ultrix.
9614 (setup_stackovf_trap): Added __P to cast.
9615 (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>)
9617 2000-01-09 René Seindal <rene@seindal.dk>
9619 * doc/m4.texinfo (Changequote): Added comment about changing
9620 quotes when the old quote is a part of the new.
9622 * src/builtin.c (expand_ranges): Added break after trailing dash.
9623 This caused misbehavious on some systems (found and fixed by Akim
9624 Demaille <demaille@inf.enst.fr>).
9626 * AUTHORS: Thomas Tanner included
9628 * acconfig.h: Added entry for ss_sp (see below).
9630 * configure.in (use_stackovf): Added check for stack_t with member
9631 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert
9632 <eggert@twinsun.com>).
9634 * doc/m4.texinfo (Frozen files): Added a simpler example for
9635 generating frozen files from several input files.
9637 1999-11-14 Paul Eggert <eggert@twinsun.com>
9639 * po/POTFILES.in: Add lib/getopt.c, lib/obstack.c,
9640 lib/regex.c, lib/xmalloc.c.

9644 * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal.
9646 * src/module.c: reindented.
9647 (module_load): return if this is a repeated load of same module.
9648 (module_init): slight change of logic to avoid repeated
9649 initialisation debug messages.
9651 * Makefile.am (DIST_SUBDIRS): Added to ensure modules/ is included
9652 in the distribution.
9654 * modules/Makefile.am (test_la_LDFLAGS): set to -module to silence
9655 automake warnings about missing lib prefix.
9656 (time_la_LDFLAGS): ditto
9657 (stdlib_la_LDFLAGS): ditto
9659 1999-11-10 Paul Eggert <eggert@twinsun.com>
9661 * src/m4.h: Include error.h, since our macros use error.
9662 * src/m4.c: Don't need to include error.h.
9664 1999-11-09 Paul Eggert <eggert@twinsun.com>
9666 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
9667 and zero, as Solaris 7 cc does.
9668 (bcopy): Remove macro; no longer needed with new obstack.h.
9670 * src/output.c (freeze_diversions): Don't assume that a
9671 diversion size can fit in `int'. Check for diversion file
9672 size too large to be printed with `unsigned long'.
9674 * src/Makefile.am (CFLAGS): Omit -Wall.
9676 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.
9678 * src/debug.c (trace_format):
9679 Use ANSI C if (defined __STDC__ && __STDC__) || defined PROTOTYPES.

9699 (ALL_LINGUAS): Added Czech translation (cs).
9701 1999-03-30 Gary V. Vaughan <gary@gnu.org>
9703 * src/builtin.c: moved module loading functions into...
9704 * src/module.c: entirely new implementation using libltdl.
9705 * po/POTFILES.in: added src/module.c.
9706 * modules/Makefile.am (LTLIBRARIES): Removed lib prefix as these
9707 are modules, not linktime libraries.
9708 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
9709 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
9710 avoidance on exported symbols.
9711 * modules/test.c (m4_macro_table, m4_init_module,
9712 m4_finish_module): ditto.
9713 * modules/time.c (m4_macro_table): ditto.
9715 * modules/time2.m4: new file which requires command line loading
9716 of modules.
9717 * src/m4.c (--load-module): dynamically load named runtime module
9718 into running executable before reading the source.
9719 (--module-directory): prepend a directory to the module search
9720 path.
9721 (module_init()): Do this the first time we load a module instead;
9722 if the module subsystem is broken normal m4 scripts can still run.
9723 * src/m4.h (install_builtin_table): is now exported.
9725 1999-03-26 Gary V. Vaughan <gary@gnu.org>
9727 * src/module.c: removed. No longer required.

9738 * src/Makefile.am (MAINTAINERCLEANFILES): ditto.
9739 * tests/Makefile.am (MAINTAINERCLEANFILES): ditto.
9741 * acinclude.m4: removed. `aclocal -I acm4' handles this much
9742 better.
9743 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
9744 * acm4/gettext.m4: removed. It causes a multiple definition vs.
9745 the installed gettext.m4 file when running aclocal.
9747 1999-03-25 Gary V. Vaughan <gary@gnu.org>
9749 * configure.in (AM_INIT_AUTOMAKE): bumped version number to
9750 distinguish this from the last prerelease.
9751 (AC_LIBLTDL_CONVENIENCE): build libltdl as a convenience library
9752 in its own subdirectory.
9754 * modules/Makefile.am (*_SOURCES): renamed to use libtool's "no
9755 lib prefix on a module" feature.
9756 (LDFLAGS): Added `-module -avoid-version' flags to build
9757 versionless module libraries.
9758 * src/builtin.c (m4_load_module): use libltdl.
9759 (module_unload_all): use libltdl.
9760 * src/m4.c (module_init): initialise module loading on demand for
9761 better diagnostics, and so that m4 will still work even if
9762 the module code is broken.
9763 * src/m4.h (module_init): removed. No longer relevant.
9764 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on
9765 exported symbols for compatibility with dlpreopening.
9766 * modules/test.c (m4_macro_table, m4_init_module,
9767 m4_finish_module): ditto.
9768 * modules/time.c (m4_macro_table): ditto.
9770 * bootstrap: New file. Runs all the autoutils in the right order
9771 after a fresh checkout, or a make maintainer-clean.
9773 1999-02-18 Akim Demaille <demaille@inf.enst.fr>
9775 * src/builtin.c (dump_symbols): New function, factoring common
9776 content of m4_dumpdef and m4_symbols.
9777 (m4_dumpdef): Use it.
9778 (m4_symbols): New function, implementing `symbols'. Use it.
9779 * doc/m4.texinfo: Fixed missing commas after @xref, so that the
9780 file compile with modern makeinfo.
9781 (Symbols): New node, documenting symbols.
9782 (direntry): Modernize.
9784 1998-12-11 René Seindal <rene@seindal.dk>
9786 * src/builtin.c (predefined_tab): New predefined macros
9787 __m4_changeword__, __m4_gmp__ and __m4_modules__ for testing for
9788 configure time options.
9790 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
9792 * src/module.c (module_try_load): Don't try to be clever and
9793 overwrite argument string. Instead allocate all constructed
9794 strings locally, since they can have arbitrary lengths. Make
9795 arguments pointers to const.
9796 (module_search): Simplify due to above change.
9798 1998-11-29 René Seindal <rene@seindal.dk>
9800 * Prerelease 1.4n.

9814 discarded, ie never returned from next_token().
9815 Added declaration of discard_comments.
9817 * src/input.c (next_token): Now loops until token type is not
9818 TOKEN_NONE. Comments are now given this type when comments should
9819 be discarded.

9827 letter option).
9829 * When configured with --with-gmp both the normal (fast) eval()
9830 and the gmp aware mpeval() are defined. To restore previous
9831 bahaviour use "define(`eval', defn(`mpeval'))".
9833 * tests/other-tests/gmp.m4: Changed to use mpeval().
9835 * src/evalmp.c: New file for compiling eval.c as gmp aware.
9836 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
9838 * src/eval.c: Now includes "numb.c" directly. Everything in this
9839 file must by static, except evaluate(), which is changed to
9840 mp_evaluate() if USE_GMP in force.
9842 * src/numb.c: Changed to be included by eval.c instead of being
9843 compiled separately. Everything is declared static.
9845 * src/numb.h: Removed declarations of functions, as numb.c is now
9846 included by eval.c.
9848 * src/builtin.c: Declaration of m4_mpeval() added.
9849 Inserted `mpeval' in builtin table.
9850 (do_eval): New function with common code for m4_eval and m4_mpeval.

9855 * src/Makefile.am (m4_SOUCES): Includes mpeval.c.
9856 (EXTRA_m4_SOURCES): Now has numb.c and numb.h
9858 * src/m4.c (main): m4 --version also shows which options were used
9859 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
9861 1998-11-27 René Seindal <rene@seindal.dk>
9863 * Error messages now always print program name before input file
9864 name as specified by GNU coding standards. Reported by Akim
9865 Demaille <demaille@inf.enst.fr>.
9867 * doc/m4.texinfo (Include): Change due to changed error message
9868 format.

9890 use new interface.
9891 (module_init): Configured default path used only if M4MODPATH is
9892 not set.
9893 (module_try_load): Now reads libMODULE.la as generated by libtool
9894 for actual module name.
9895 (module_load): Gives better error messages on failure.
9897 * src/m4.h: Added declarations of structures and functions for
9898 generic search path handling.
9900 * src/path.c: Removed all module specific code and introduced new
9901 functions of more generic search path handling.
9903 1998-11-24 René Seindal <rene@seindal.dk>
9905 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
9906 included gettext, as <libintl.h> might not be found
9907 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
9909 1998-11-22 René Seindal <rene@seindal.dk>
9911 * src/output.c (insert_diversion): Fixed bug that might cause m4
9912 to read from standard output! Triggered by input
9913 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
9914 so now 'undivert(0)' does nothing.
9916 1998-11-18 René Seindal <rene@seindal.dk>
9918 * Prerelease 1.4m.
9920 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
9921 could be changed when compiling a illegal regexp, causing later

9925 standards.
9927 * src/m4.c (usage): Added message about reporting bugs.

9938 with libtool.
9940 * modules/Makefile.am: Changed completely to compile modules using
9941 libtool. The modules are compiled as shared libraries, and are
9942 renamed when installed.
9944 * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
9945 USE_SHL_LOAD to HAVE_SHL_LOAD
9947 * src/builtin.c (shipout_string): Now tests for a NULL string.
9949 * src/module.c: New level of indirection around non-portable
9950 functions to load shared objects. Intended to encapsulate the non
9951 portable parts better and to reduce the number of #ifdefs in the
9952 code.
9954 * Makefile.am (DIST_SUBDIRS): Instead of EXTRA_DIST for added
9955 directory modules/ to the distribution.
9957 1998-11-15 René Seindal <rene@seindal.dk>

9973 * modules/Makefile.am: Now correctly compiles and installs
9974 modules in pkglibexecdir.
9976 * src/m4.h: WITH_MODULES defined iff HAVE_DLOPEN or USE_SHL_LOAD.
9977 These two are now initialised by autoconf macros.
9979 * src/path.c (module_env_init): MODULE_PATH is always on the
9980 search path.
9982 * src/Makefile.am: Now generated pathconf.h which defined the
9983 default MODULE_PATH.
9985 * configure.in (pkglibexecdir): Added defintion of pkglibexecdir,
9986 where modules are installed.
9988 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
9989 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
9990 build and install automatically, and it is prepared for other
9991 interfacec than dlopen().
9993 * src/builtin.c (predefined_tab): Added __m4_version__ for the
9994 current version of GNU m4. It is a GNU extension.
9996 1998-11-14 René Seindal <rene@seindal.dk>
9998 * tests/Makefile.am (GENERATED_TESTS): Added new
9999 generated-tests/changesy.8.test

10012 (input_init): Added initialisation of use_macro_escape.
10013 (check_use_macro_escape): New function to synchronise
10014 use_macro_escape with the syntax table.
10015 (set_quotes): Added call to check_use_macro_escape()
10016 (set_comment): Do.
10017 (set_syntax): Do.

10027 generated-tests.
10029 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): Added manually
10030 maintained tests in tests/other-tests. These currently tests for
10031 8-bit transparency, multiple precision arithmetic and sync-line
10032 output. Test for stackoverflow detection does not work.
10034 * examples/Makefile.am (TESTS): Added tests for all example files.
10036 * examples/mktests.sh: New file. Help program for creating test
10037 files.

10074 1998-10-07 René Seindal <rene@seindal.dk>
10076 * Prerelease 1.4j.
10078 * tests/Makefile.am (GENERATED_TESTS): Changed .m4 extension to
10079 .test, as the files are no longer just m4 input.
10081 * tests/get-them (FILE): Changed .m4 extension to .test.
10083 * src/m4.h (token_type): New token type TOKEN_SPACE introduced.
10084 Otherwise quoted strings with leading whitespace first in a macro
10085 argument would be eliminated.
10087 * src/macro.c (expand_token): Handles new token type TOKEN_SPACE.
10088 (expand_argument): Do.
10090 * src/input.c (next_token): SPACE and NUM/OTHER characters are only
10091 grouped together iff both quote and comment strings are single
10092 character. Otherwise they might include a comment/quote leader.
10093 (next_token): Returns new token type TOKEN_SPACE.
10095 * src/builtin.c (push_builtin_table): New function to push a
10096 builtin_table on the stack without installing its contents.
10097 (find_builtin_by_name): Added call to push_builtin_table() if
10098 reading frozen files. Otherwise the builtins named in the frozen

10119 * src/module.c: New file, implements the OS dependant parts of
10120 dynamic module loading.
10122 * src/Makefile.am (m4_SOURCES): Added module.c
10124 * src/builtin.h: New file, declares some functions from builtin.c
10125 that are of use for other modules (shipout_int, numeric_arg,
10126 skip_space, bad_argc), and the macros ARG() and DECLARE().
10128 * src/builtin.c (install_builtin_table): New function. Each
10129 module brings in a builtin_table, which is pushed on a stack.
10130 (struct builtin_table): New struct for list of builtin_tables.
10131 (m4_loadmodule): New function to implement builtin "loadmodule".
10132 (shipout_int): No longer static, to be used by modules.
10133 (numeric_arg): do.

10143 * src/m4.h: Added declarations for new functions in module.c and
10144 in path.c.
10146 * src/m4.c (main): Added call to module_init().
10148 * modules: New directory with a few demo modules.
10150 * Makefile.am (EXTRA_DIST): Added modules/* since modules/ is not
10151 in SUBDIRS.
10153 * configure.in: Added modules/Makefile to AC_OUTPUT.
10155 * configure.in: Added code to implement --with-modules. Tests for
10156 <dlfcn.h> and -ldl.
10158 * acconfig.h: Added WITH_MODULES
10160 1998-10-02 René Seindal <rene@seindal.dk>
10162 * examples/Makefile.am (pkgdata_DATA): Removed special target for
10163 check and variables TESTS. These tests are now run from the
10164 tests/ directory.
10166 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
10167 directory. The files stay there but the tests are run from the
10168 tests/ directory.
10170 * tests/Makefile.am (EXTRA_DIST): Added run-test.
10172 * tests/run-test: New file. Run a test manually
10174 * tests/Makefile.am, tests/get_them: Moved automatically generated
10175 tests (from the manual) to sub directory tests/gentest/. The
10176 tests/ directory had gotten a bit messy.
10178 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10180 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\
10181 wrap}.test: Added a few testcases.
10183 1998-08-21 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10185 * Prerelease 1.4h.
10187 * lib/Makefile.am (noinst_HEADERS): regex.h added
10189 * configure.in (jm_WITH_REGEX, jm_PREREQ_ERROR):
10190 acm4/{error,regex}.m4 (from fileutils-3.16u.tar.gz).
10192 * acm4/Makefile.am: created providing rules to create
10193 $(top_srcdir)/acinclude.m4 to be used by aclocal.
10195 * tests/defs (LANGUAGE, LC_ALL, LANG): force them to be
10196 `C'. Reported by Ulrich Drepper.
10198 * Makefile.am (SUBDIRS): Removed checks directory
10199 * configure.in (AC_OUTPUT): Removed checks/Makefile
10201 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
10202 the space when m4.texinfo is edited and whitespace.el is active.
10203 (Defn,example): idem.
10205 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10207 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
10208 ../COPYING. ../Makefile is a file which is certainly present when
10209 test is executed in testSubDir. One can't be sure that the COPYING
10210 file is in .. or ../.. in all situations, the ../Makefile is
10211 always there.
10213 * doc/m4.texinfo (Include): adjusted expected test output
10214 according to new tests, i.e. the input will always come from the
10215 file `in' created by the test.
10217 * tests/Makefile.am: Added three lines at the top to get
10218 esyscmd.1.test working.
10220 * tests/get-them: modified to generate clearer tests who will need
10221 less maintenance when new test examples are created in
10222 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
10223 need the generic file `defs') shell scripts creating `in', `ok',
10224 `out' and when apropriate `okerr' and `err' in the directory
10225 `testSubDir' when executed. The compare of `ok' and `out'
10226 (and of `okerr' and `err') will be the exit status of the test.
10227 `out' must match `ok' (and `okerr' must match `err') for the test
10228 to be succesful.
10230 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
10231 the tests generated by tests/get-them getting it input normally
10232 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
10233 (dot) before the numeric part) is reserved for all other (hand
10234 written) tests. The `+' means one or more times.
10236 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10238 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
10239 supported short man page to refer to info documentation
10240 * helptoman.pl: added
10241 * configure.in: AC_PATH_PROG(PERL,perl)
10242 * Makefile.am (SUBDIRS): doc after src
10244 * libitized with libit 0.5 from
10245 ftp://ftp.iro.umontreal.ca/pub/contrib/pinard/maintenance/libit.

10252 * configure.in (AC_CHECK_FUNC): getopt_long
10254 * src/m4.c (usage): Report bugs to m4-bugs@gnu.org.
10256 * TODO: added entry about dependencies
10258 1998-08-10 René Seindal <rene@seindal.dk>
10260 * Prerelease 1.4f
10262 * doc/m4.texinfo (Changesyntax): Added documentation for the macro
10263 "changesyntax".
10265 * src/builtin.c (m4_changesyntax): Added builtin macro
10266 "changesyntax" to modify the syntax table.
10268 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax
10269 table. All categories are assigned a syntax code and tokens are
10270 read according to this table.
10272 1998-08-09 René Seindal <rene@seindal.dk>
10274 * src/numb.{c,h}: New files, implements multiple precision eval
10275 using GNU gmp. Originally submitted by John Gerard Makecki
10276 (johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.
10278 * doc/m4.texinfo (Eval): Added documentation for multiple
10279 precision arithmetic library support.
10281 * src/m4.{c,h}, src/eval.c, src/builtin.c, configure.in: Changes
10282 to accommodate multiple precision eval.
10284 1998-08-07 René Seindal <rene@seindal.dk>
10286 * src/input.c (MATCH, match_input), src/m4.h: changed definition
10287 of comment and quote strings to `unsigned int' to allow eight bit
10288 chars (reported by andrewb@zip.com.au (Andrew Bettison)).
10290 * src/builtin.c, doc/m4.texinfo: Builtin `syncoutput' added by
10291 patch from Mike Howard <mike@clove.com>
10293 1998-08-06 René Seindal <rene@seindal.dk>
10295 * gettext.m4: corrected AM_WITH_NLS to handle use of installed

10303 and _ macro. M4 now builds with --disable-nls.
10305 * src/m4.c (main): reintroduced textdomain(PACKAGE) to get gettext
10306 to look for right message catalogs. Call indef'ed by ENABLE_NLS.
10308 * configure.in (ALL_LINGUAS): Added complete list of translations:
10309 de fr it ja nl ru sv.
10311 1998-05-23 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10313 * po/nl.po: Dutch translation by Erick Branderhorst.
10315 * po/fr.po: French translation by Erick Branderhorst, based on the

10320 * Prerelease 1.4d.
10322 * src/m4.c: #include <signal.h> not <sys/signal.h>.
10324 * src/Makefile.am: CFLAGS = -Wall @CFLAGS@.

10328 * configure.in, {,src,doc,lib,examples,checks}/Makefile.am,
10329 src/{ansi2knr.{1,c}} doc/{m4.texinfo,mdate-sh}, missing,
10330 mkinstalldirs, install-sh: Added automake (1.3) support.
10332 * lib/{alloca.c,error.{c,h},get{date.h,opt.{c,h},opt1.c},
10333 obstack.{c,h},regex.{c,h},strtol.c,xmalloc.c,xstrdup.c}:
10334 Used libitize (0.4) to update.
10336 * configure.in, ABOUT-NLS, intl/*, po/*: Added gettextize
10337 (0.10.25) support. Removed LOCALE, fr.msg, m4.cod and adjusted
10338 README accordingly.

10420 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
10421 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler

10440 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
10441 Remove the sed filter after ansi2knr for debug.c. Use $O instead
10442 of $U, put underline in extensions rather than in basenames. Use
10443 implicit rules, now that regularity makes this possible.
10444 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
10445 of ansi2knr whenever it is needed.
10446 * configure.in: Adjusted for correct STACKOVF substitution.
10447 * src/debug.c (trace_format): When not __STDC__, use (...) as a
10448 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.

10538 * Release 1.3.
10540 * Makefile.in: Group all *clean-recursive goals in one, using sed

10546 Reported by Kaveh R. Ghazi.
10548 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS

10610 * src/builtin.c (builtin_init): Merge in functionality from
10611 previous prefix_all_buitins function, while making entries in the
10612 symbol table, but not modifying the builtin description itself.
10614 * src/freeze.c (reload_frozen_state): Add a useless `break;',
10615 because *many* compilers do not accept an empty `default:'.

10625 * Makefile.in (check): Don't.
10626 Reported by Akiko Matsushita and Jim Meyering.
10628 * src/output.c (make_room_for, output_character_helper): New

10694 1994-08-27 François Pinard <pinard@iro.umontreal.ca>
10696 * symtab.c (hack_all_symbols): Use hash_table_size instead of

10810 * builtin.c (numeric_arg): Use strtol and verify the conversion,
10811 instead of using sscanf which stops as soon as there is a
10812 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
10813 and divert(1xyzzy) were all accepted without any warning or error
10814 messages.
10815 * m4.h: Declare strtol as long if not including stdlib.h.
10816 * configure.in: Check for limits.h, and replace strtol if missing.

10833 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
10834 handlers), and a default error message if the fault address is not
10835 available (when neither siginfo.h nor BSD sigcontext are supported).
10836 * configure.in: Changes for stackovf.h: Check for sigcontext,
10837 sigaction, sigstack, and define rlim_t as int if necessary.
10838 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
10839 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
10840 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
10842 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
10844 * configure.in: Use AC_SET_MAKE.
10845 * Makefile.in: Use @SET_MAKE@.
10846 Reported by Jim Meyering.
10848 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
10849 Reported by Ian Taylor.
10851 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
10853 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
10854 because siginfo.h is unrelated to standard headers, and siginfo.h
10855 is already checked for.
10856 Reported by Joseph E. Sacco.
10858 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
10859 PROTOTYPES.
10860 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
10861 AC_PROTOTYPES.
10863 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
10865 * builtin.c (substitute): Use \& to represent this part of the
10866 string which was matched by the whole regexp, instead of
10867 representing the whole string. Any usage of \0 issues a warning
10868 and acts like \&, it will disappear in some subsequent release.
10870 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
10872 * m4.c: Complete prototype for forwarded declaration of usage.
10874 * input.c (init_macro_token): Correct own reference in error
10875 message. Previous name get_macro_func was referred to instead.
10876 (next_char): Correct own reference in error message. Previous
10877 name advance_input was referred to instead.
10879 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
10880 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
10881 and_term, not_term, logical_not_term, cmp_term, shift_term,
10882 add_term, mult_term, exp_term, unary_term, simple_term): Add
10883 prototype to forwarded declarations. Declare parameter v1 as
10884 eval_t * instead of int *. Same for local variable v2 in dyadic
10885 functions. Same for result in exp_term.
10886 * builtin.c (m4_eval): Declare value as eval_t instead of int.
10887 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
10888 unsigned_eval_t instead of unsigned int. Change casts accordingly.
10889 (shipout_int): Cast first argument of ntoa to eval_t.
10890 Reported by Thorsten Ohl.
10892 * macro.c: Complete the prototypes of forwarded expand_macro and
10893 expand_token.
10894 Reported by Thorsten Ohl.
10896 * m4.h: Define voidstar as void * or char * depending on __STDC__.
10897 The Ultrix 3.1 compiler cannot do much with void pointers.
10899 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
10900 * m4.c (xfree): Replace void * by voidstar.
10901 Reported by Tom McConnell.
10903 * ansi2knr.1: New, from elsewhere.
10904 * Makefile.in (DISTFILES): Distribute ansi2knr.1
10906 * Makefile.in (stamp-h.in): Avoid running ./config.status if
10907 stamp-h does not exist yet. This avoids running it a second time
10908 just after the initial ./configure.
10909 Reported by David MacKenzie and Tom McConnell.
10911 * m4.h: Replace the enum debug_info declaration with a series of
10912 #define's. The Ultrix 3.1 compiler would otherwise need casting
10913 (int) to most references, when used in expressions.
10914 Reported by Tom McConnell.
10916 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
10918 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
10919 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
10920 calls the compiler. Previously, FP_PROTOTYPES was only calling
10921 the preprocessor; by not being subject to CFLAGS, this was
10922 discouraging those flags asking for ANSI compilation.
10923 * acconfig.h: Document HAVE_PROTOTYPES.
10924 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
10925 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
10926 Reported by Eric Backus.
10928 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
10929 from the environment. Default CFLAGS to -g if not set.
10930 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
10931 * lib/Makefile.in: Have CFLAGS substituted from configure.
10932 Reported by Eric Backus and Tom McConnell.
10934 * configure.in: m4_undefine changeword before using AC_ENABLE.
10936 * m4.h: Declare prototypes for error (for ANSI compilers only),
10937 prefix_all_builtins and reference_error.
10938 Reported by Tom McConnell.
10940 * input.c (set_word_regexp): Do not try to initialize the array
10941 test from a string, this does not work with non-ANSI compilers.
10942 Reported by Eric Backus.
10944 * Makefile.in (dist): Clean examples/ before saving it.
10945 (distclean-local): Also remove stamp-h.
10946 Reported by Eric Backus.
10948 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
10949 non ANSI compilers.
10950 Reported by Tom McConnell.
10952 * checks/Makefile.in (clean): Depends on mostlyclean.
10953 (mostlyclean): New goal.
10955 1994-06-24 François Pinard <pinard@iro.umontreal.ca>
10957 * Makefile.in (DISTFILES): Distribute install.sh.
10958 * install.sh: New file, copied from elsewhere.
10959 Reported by Assar Westerlund and Kaveh R. Ghazi.
10961 1994-06-23 François Pinard <pinard@iro.umontreal.ca>
10963 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
10964 * acconfig.h: Explain ENABLE_CHANGEWORD.
10966 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
10967 from code provided by Pete Chown]
10968 * m4.h: Add original_text field to u_t variant of union u.
10969 Declare TOKEN_DATA_FUNC macro.
10970 * builtin.c: Declare changeword.
10971 (m4_changeword): New function.
10972 * input.c: Include "regex.h", define variables with word regexps.
10973 (input_init): Initialize the word regexp.
10974 (set_word_regexp): New.
10975 (next_token): Declare local variables, use the previous code if
10976 default_word_regexp is true. Else, match using a new code. Save
10977 the original text.
10978 * macro.c (expand_token): Ship out original text if not a macro
10979 name.
10980 Reported by Krste Asanovic and Pete Chown.
10982 [These modifs all depend upon ENABLE_CHANGEWORD]
10983 * m4.h: Declare external user_word_regexp.
10984 * m4.c: Declare user_word_regexp, and initialize it from
10985 --word-regexp or -W, or NULL if not specified.
10986 * input.c: Use user_word_regexp if specified, instead of
10987 DEFAULT_WORD_REGEXP.
10989 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
10990 agree with it.
10992 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
10993 * checks/Makefile.in: Empty the suffix list.
10994 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
10996 * m4.c: Declare nesting_limit and initialize it to 250.
10997 Implement -LNUMBER or --nesting-limit=NUMBER to change its
10998 value.
10999 * m4.h: Declare nesting_limit as external.
11000 * macro.c (expand_macro): Stop execution whenever nesting limit
11001 is exceeded.
11002 Reported by Bengt Mertensson.
11004 * eval.c (evaluate): Diagnose excess characters in eval input.
11005 Things like `eval(08)' used to return 0 with no diagnostic.
11007 * m4.h: Capitalize first letter of all macro arguments in
11008 definitions.
11010 * m4.c: Declare warning_status, initialize it to 0. Add new
11011 option -E, or --fatal-warnings, which sets warning_status to
11012 EXIT_FAILURE instead.
11013 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
11014 EXIT_FAILURE if not otherwise done by header files.
11015 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
11016 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
11017 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
11018 argument of all M4ERROR calls.
11019 Reported by Noah Friedman.
11021 * examples/incl-test.m4: Renamed from incl_test.m4.
11022 * examples/include.m4: Include incl-test.m4 instead of
11023 incl_test.m4.
11024 * examples/multiquotes.m4: Renamed from multi-quotes.m.
11026 1994-06-22 François Pinard <pinard@iro.umontreal.ca>
11028 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
11029 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
11030 also tested it on a Sun Sparc workstation running SunOS 4.x.
11032 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
11033 49.format check, abusing a `union values' argument with sprintf
11034 without selecting the proper field. Now, save the formatting type
11035 first, delaying the fetch of the corresponding argument.
11036 Reported by Joseph E. Sacco and Tom Quinn.
11038 * format.c (format): Remove const from char *fmt declaration when
11039 not HAVE_EFGCVT, because a NUL may be forced into it.
11041 * m4.h: Declare atof() when not STDC_HEADERS.
11042 Reported by Joseph E. Sacco.
11044 * Regenerate configure using Autoconf 1.11, this corrects a
11045 problem about an incorrect cpp seting on NeXT 3.1.
11046 Reported by Alexander Lehmann.
11048 1994-06-05 François Pinard <pinard@iro.umontreal.ca>
11050 * m4.h (_): Change argument from `x' to `Args'.
11052 1994-04-22 François Pinard <pinard@iro.umontreal.ca>
11054 * m4.h: Rename Args() to _().
11055 * m4.h: Remove extern specifier from all function declarations.
11057 1994-04-22 Jim Avera <jima@netcom.com>
11059 * stackovf.c: New file implementing stack-overflow detection.
11060 * configure.in: Check for getrlimit, sigaction. If all of
11061 standard headers, getrlimit and sigaction, define USE_STACKOVF and
11062 substitute ${U}stackovf.o for STACKOVF.
11063 * acconfig.h: Declare USE_STACKOVF.
11064 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
11065 * m4.h: Declare setup_stackovf_trap().
11066 * m4.c: Call setup_stackovf_trap().
11067 * tests/stackovf_test.sh: New file.
11069 1994-04-13 François Pinard <pinard@iro.umontreal.ca>
11071 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
11073 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
11075 1994-01-30 François Pinard <pinard@iro.umontreal.ca>
11077 * m4.h: Remove definition of volatile, not used anymore.
11078 Reported by Jim Meyering and Joseph E. Sacco.
11080 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
11081 of `if ... else /* nothing */' for if macros.
11082 Reported by Jim Meyering.
11084 * builtin.c (m4_regexp): Reorganize the code for avoiding a
11085 warning from gcc about `repl' possibly used before defined.
11086 Reported by Jim Meyering.
11088 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
11089 Reported by Jim Meyering.
11091 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
11093 * m4.h: Move the conditional definition of volatile after the
11094 inclusion of system files, because they may define it first.
11096 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
11098 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
11099 get around a problem with Alpha make seeing a syntax error, there.
11100 Reported by Vern Paxson.
11102 1994-01-03 François Pinard <pinard@iro.umontreal.ca>
11104 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
11105 Reported by Richard Stallman.
11107 1993-12-25 François Pinard <pinard@iro.umontreal.ca>
11109 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
11110 instead of AC_HAVE_FUNCS.
11111 Reported by Noah Friedman.
11113 1993-12-01 François Pinard <pinard@iro.umontreal.ca>
11115 * m4.c: Initialize show_help and show_version to zero.
11117 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
11118 Use them in exit() and usage() calls.
11120 1993-11-27 François Pinard <pinard@iro.umontreal.ca>
11122 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
11123 syserr() macro. Delete errref, add reference_error and M4ERROR.
11124 * m4.c: Replace errref, which was returning an input reference
11125 string, with reference_error, which prints it on standard error.
11126 * builtin.c, output.c: Use errno as second parameter to error,
11127 instead of using syserr() with %s.
11128 * *.c: Use M4ERROR instead of error: no more errref() with %s.
11129 Doing so, the program name appears after the input reference
11130 instead of before, which eases M-x next-error processing.
11132 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
11134 * checks/get-them: Escape braces with backslashes in patterns,
11135 because HPUX-9.01 awk needs this.
11136 Reported by Jim Meyering.
11138 1993-11-22 François Pinard <pinard@iro.umontreal.ca>
11140 * builtin.c: Declare "FILE *popen ();".
11142 * m4.h: Remove MESSAGE{,1,2}, WARNING1, FATAL{,1}, INTERNAL_ERROR
11143 macros, replace error_message_prefix() declaration by errref()'s.
11144 Declare xrealloc, for use in errref().
11145 * m4.c: Delete error_message_prefix() function, add errref().
11146 * *.c: Use error() systematically in place of all error macros,
11147 now that error() flushes stdout first. Make needed adjustments.
11149 * m4.h: Remove const in sys_errlist[] declaration, it creates
11150 conflicts on SGI and Alpha.
11151 Reported by Kaveh R. Ghazi.
11153 1993-11-20 François Pinard <pinard@iro.umontreal.ca>
11155 * m4.c: Include <getopt.h> instead of "getopt.h".
11157 * configure.in: Output to config.h. Use HAVE_FUNCS preferably.
11158 * acconfig.h: New, for documenting HAVE_EFGCVT.
11159 * Makefile.in: Distribute acconfig.h, .stamp-h.in and config.h.in,
11160 use them wherever appropriate. Also use -I. for compilations.
11161 * lib/Makefile.in: Use -I.. for compilations.
11162 * *.c: Include <config.h> or "config.h".
11164 * m4.h: Test for HAVE_MEMORY_H instead of NEED_MEMORY_H.
11165 * configure.in: Use AC_HAVE_HEADERS(memory.h), delete AC_MEMORY_H.
11167 1993-11-17 François Pinard <pinard@iro.umontreal.ca>
11169 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
11171 * input.c (input_init): Initialize quote and comment strings
11172 explicitely instead of calling set_quotes and set_comment: by
11173 doing so, we ensure we do not free uninitialized variables.
11175 * checks/check-them: Reverse arguments to both diff, so the
11176 expected is on the left and the obtained on the right.
11178 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
11179 macros. Delete declarations for m4error, warning, fatal and
11180 internal_error, add declaration for error_message_prefix.
11181 * m4.c: Delete m4error, warning, fatal and internal_error
11182 routines, add error_message_prefix routine.
11183 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
11184 warning with WARNING*, fatal with FATAL* and internal_error with
11185 INTERNAL_ERROR*.
11186 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
11187 this is not needed anymore.
11189 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
11190 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
11191 and debug_message, add declaration for debug_message_prefix.
11192 * debug.c: Remove static specifier for FILE *debug declaration.
11193 Delete debug_print and debug_message routines, add
11194 debug_message_prefix routine.
11195 * builtin.c, debug.c: Replace debug_print routine calls with
11196 DEBUG_PRINT* macro calls.
11197 * input.c, path.c: Replace debug_message routine calls with
11198 DEBUG_MESSAGE* macro calls.
11200 * m4.h: Remove inclusion of <varargs.h>.
11201 * debug.c: Include <stdarg.h> or <varargs.h>.
11202 (trace_format): Use stdarg instead of varargs if __STDC__.
11204 * configure.in: Remove checks for vfprintf and _doprnt. These
11205 implementations use varargs tricks which are not portable enough.
11206 * lib/vfprintf.c: Deleted.
11207 * lib/_doprnt.c: Deleted.
11208 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.
11209 Reported by Joel Sherrill.
11211 * path.c (add_include_directory): Use xstrdup.
11213 * builtin.c (find_builtin_by_name): Declare static.
11215 * *.[ch]: Add const to a few "char *" declarations.

11222 * builtin.c (m4_syscmd, m4_esyscmd): Use it.
11223 Reported by Nicolas Pioch.
11225 1993-11-12 François Pinard <pinard@iro.umontreal.ca>
11227 * Makefile.in (m4.dvi): Use m4.texinfo instead of m4.texi.
11228 Reported by Joel Sherrill.
11230 * builtin.c (prefix_all_builtins): Instead of the table size, use
11231 the null entry at end for stopping the loop. It was overwritten.
11232 Reported by Andreas Schwab and Jim Meyering.
11234 * builtin.c (prefix_all_builtins): Cast xmalloc to (char *).
11235 Reported by Kaveh R. Ghazi.
11237 * macro.c (call_macro): Add * in (*SYMBOL_FUNC (sym)) (...).
11238 Reported by Karl Vogel.
11240 1993-11-09 François Pinard <pinard@iro.umontreal.ca>
11242 * m4.h: Do not define volatile if already defined.
11243 Reported by René Seindal.
11245 * lib/Makefile.in: Add a forgotten ALLOCA=@ALLOCA@. Grrr!
11247 Reported by Bernhard Daeubler, Eric Backus, Hal Peterson, Hoang
11248 Uong, Ian Taylor, Kaveh R. Ghazi, Tom McConnell and Walter Wong.
11250 1993-11-08 François Pinard <pinard@iro.umontreal.ca>
11252 * m4.h: Define strchr and strrchr in terms of index and rindex,
11253 instead of the other way around.
11254 * builtin.c, m4.c, path.c: Use strchr instead of index.
11256 * input.c (next_char): Remove a "break;" after a "return ...;".
11257 Reported by Tom McConnell.
11258 \f
11259 1993-11-08 François Pinard <pinard@iro.umontreal.ca>
11261 * Release 1.1
11263 * configure.in: Do not copy check files in the build hierarchy.
11264 * checks/check-them: Identify the m4 version being checked. For
11265 finding m4, look in $PATH instead of in the parent directory.
11266 * Makefile.in (check): Prepend `pwd` to $PATH before checking.
11267 * checks/Makefile.in (.all-stamp): Always create check files in
11268 the source hierarchy, not anymore in the build hierarchy.
11269 (check): cd to the source hierarchy before performing checks.
11270 Do not copy nor clean COPYING anymore, take it from `..'.
11271 Reported by Tom McConnell.
11273 * Makefile.in (Makefile): Use $(SHELL).
11274 (config.status): Use $(SHELL). Use "config.status --recheck"
11275 instead of "configure --no-create", which is obsolete.
11276 Reported by Tom McConnell.
11278 1993-11-05 François Pinard <pinard@iro.umontreal.ca>
11280 * m4.c (usage): Use "%s" instead of "m4" in format string.
11281 Reported by Jim Meyering.
11283 * Makefile.in: Distribute mkinstalldirs.
11284 Reported by Pierre Gaumond.
11285 Reported by Jim Meyering.

11290 * checks/get-them: Renamed from checks/get_them.
11291 * checks/.all-stamp: Renamed from checks/.all_stamp.
11292 * checks/Makefile.in: Changed accordingly.
11293 Reported by Jim Meyering.
11295 1993-11-04 François Pinard <pinard@iro.umontreal.ca>
11297 * lib/Makefile.in (dist): Correct permissions on files.
11299 * output.c: Declare tmpfile, some systems don't.
11301 1993-11-03 François Pinard <pinard@iro.umontreal.ca>
11303 * checks/Makefile.in (dist): Correct permissions on files.
11305 * Makefile.in (dist): Ensure recursive linking for subdirectory
11306 `examples', also set read/write permissions on all its files.
11308 * mkinstalldirs: New, from elsewhere.
11309 * Makefile.in: Use it.
11311 * debug.c: Synchronize debug messages and regular output when
11312 the debug file and stdout are redirected to the same file.
11313 * configure.in: Add (commented) checks for fileno and fstat.
11314 Reported by Jim Avera.
11316 * builtin.c (m4_ifelse): Diagnose excess arguments if 5, 8, 11,

11424 * Makefile.in, lib/Makefile.in, check/Makefile.in: In dist goals,
11425 ensure 777 mode for directories, so older tar's will restore file
11426 modes properly.
11428 1993-01-17 François Pinard <pinard@iro.umontreal.ca>
11430 * Makefile.in, lib/Makefile.in: Put $(CFLAGS) after $(CPPFLAGS),
11431 so the installer can override automatically configured choices.
11432 Reported by Karl Berry.
11434 1993-01-15 François Pinard <pinard@iro.umontreal.ca>
11436 * lib/vfprintf.c: Stolen from Oleo distribution and adapted. The

11445 1993-01-01 François Pinard <pinard@iro.umontreal.ca>
11447 * Makefile.in, lib/Makefile.in: Reinstate $(CPPFLAGS), use it.
11448 Richard wants it there.

11457 1992-12-23 François Pinard <pinard@iro.umontreal.ca>
11459 * Makefile.in (dvi, m4.dvi): New goals.
11461 * builtin.c, eval.c, format.c, input.c, m4.[ch], m4.texinfo,
11462 macro.c, output.c, path.c, symtab.c: Change Copyright from
11463 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
11465 * examples/divert.m4: Deleted, this bug has been corrected.
11467 * Makefile.in (texclean, mostlyclean): New goals.
11469 * Makefile.in (clean): Remove clutter from ansi2knr.
11470 Reported by Pierre Gaumond.
11472 1992-12-20 François Pinard <pinard@iro.umontreal.ca>
11474 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
11475 might well use CFLAGS is s/he needs it.
11477 * Makefile.in: Allow installation of info files from a separate
11478 build directory.
11479 Reported by Jason Merrill.
11480 Reported by David MacKenzie.
11481 Reported by Skip Montanaro.
11482 Reported by Erez Zadok.
11483 Reported by Assar Westerlund.
11484 \f
11485 1992-12-19 François Pinard <pinard@iro.umontreal.ca>
11487 * Release 1.0.3
11488 This is still a beta release for the future GNU m4 version 1.1.
11490 * lib/alloca.c: New, from elsewhere.
11491 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
11493 * m4.h: Do not define index/rindex if already defined. If
11494 FALSE/TRUE are already defined, do not redefine them, but merely
11495 define boolean typedef to int.
11497 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
11498 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
11499 because some C compilers do not like connectives with #ifdef.
11500 * m4.h: Define `volatile' only if __GNUC__, instead of once for
11501 __GNUC__ and once for __STDC__.
11502 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
11504 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
11505 Makefile dependencies. Without it, make keeps destroying and
11506 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
11508 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
11509 to diversion/DIVERSION, this was a spelling error.
11511 * m4.c: Declare version[], remove #include "version.h".
11512 * version.h: Deleted.
11513 * Makefile.in: Remove references to version.h.
11515 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
11516 production, by using a simpler and more robust algorithm. This
11517 solves the problem of synclines sometimes written in the middle of
11518 an output line. Delete sync_line() and output_lines variable.
11519 * m4.h: Remove sync_line prototype and output_lines declaration.
11520 * input.c (next_char), output.c (shipout_text): Remove references
11521 to output_lines.
11522 * input.c (push_file, pop_file): Merely put the value -1 in
11523 output_current_line instead of calling sync_line, for delaying a
11524 single `#line NUM FILE' before next output line. Do not test
11525 for sync_output, because this is unnecessary clutter.
11526 * output.c (make_divertion, insert_divertion): Idem.
11527 * input.c: Rename must_advance_line to start_of_input_line, for
11528 consistency.
11530 * debug.c (trace_header): Select a new debug line format, which
11531 better complies with GNU standards for formatting error messages.
11532 With option `-dfl', M-x next-error might be used on the output.
11533 * m4.c (vmesg): Adjust format of error output to GNU standards.
11534 * m4.texinfo: Adjust examples for `make check' to work.
11536 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
11537 case for enum debug_info constants, which were all lower case.
11539 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
11540 re_search_2.
11541 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
11542 collected patches. I tried a few times using newer regex.[ch], it
11543 mysteriously stopped aborting with this one. Insecure feeling...
11544 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
11546 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
11548 * m4.c: Change `--no-warnings' to `--silent'.
11549 Reported by David MacKenzie.
11551 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
11552 leave it off for now. See comment in m4.c for justification.
11553 Reported by David MacKenzie.
11555 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
11556 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
11558 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
11560 * Makefile.in: Ensure recursive cleaning is done before local
11561 cleaning for all clean goals.
11563 * builtin.c (ntoa): Ensure the value is always interpreted as a
11564 signed quantity, whatever the radix is.
11566 1992-11-18 Jim Meyering <meyering@idefix>
11568 * builtin.c, format.c, input.c: Split long lines.
11569 * m4.c: Use typedef macro_definition instead of struct
11570 macro_definition.
11571 * symtab.c: Use typedef symbol instead of struct symbol.
11573 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
11575 * *.[ch]: Remove all trailing whitespace, in code and comments.
11577 * configure.in: Find some awk.
11578 * Makefile.in: Add $(AWK) to MDEFINES.
11579 * checks/Makefile.in: Transmit $(AWK) to get_them.
11580 * checks/get_them: Use $AWK instead of gawk. Add a close in the
11581 awk script when switching files, because without this, mawk runs
11582 out of file descriptors.
11584 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
11586 * Makefile.in (realclean): Delete m4.info*.
11587 Reported by Jim Meyering.
11589 * Makefile.in: Adjust and link with checks/Makefile.
11590 * checks/Makefile.in: New.
11591 * configure.in: Output checks/Makefile.
11593 * checks/get_them: Have the dnl header of each test more
11594 recognizable by next-error, also use a better message.
11596 1992-11-16 Jim Meyering <meyering@idefix>
11598 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
11599 And use that only if __GNUC__ since we're using it's GCC-specific
11600 semantics that tell the compiler the associated function doesn't
11601 return.
11603 * builtin.c (substitute): Don't use character as an array index.
11604 (dumpdef_cmp): Make formal arguments `const void *' to avoid
11605 warnings with gcc -W -Wall on systems with qsort prototype.
11606 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
11607 from gcc -W -Wall.
11609 * eval.c (most functions): Add parentheses to assignments used
11610 as truth values go avoid warnings from gcc -Wall.
11612 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
11613 any functions that don't need external scope.
11615 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
11616 (many functions and arrays): Declare `const'.
11618 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
11620 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
11621 removing the declaration from m4.h. Also rename false to FALSE
11622 and true to TRUE.
11624 * lib/Makefile.in (Makefile): New goal.
11626 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
11627 so heavily loaded. It gets more easily overridable, calling make.
11628 Reported by Jim Meyering.
11630 * Makefile.in (dist): Get .fname from the current directory name,
11631 instead of from version.h. I need updating many files manually,
11632 when the version changes, version.h is just one of them.
11634 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
11636 * m4.h: Remove the tag `boolean' on the enum introducing typedef
11637 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
11638 Reported by Tom McConnell.
11640 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
11642 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
11643 39.cleardiv, which were describing missing or spurious newlines.
11644 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
11645 do not depend on machine word size, `/bin/false' implementation,
11646 or `wc' output format. `make check' is more dependable, now.
11648 * checks/check_them: Summarize the failed tests by listing their
11649 name, at end. If none, issue `All checks successful'. Output
11650 `Checking' instead of `Input file:'.
11652 * checks/get_them, checks/check_them: Reindented.
11654 * Makefile.in (dist): chmod a+r before making the tar file.
11656 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
11658 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
11660 * input.c (next_token): Reinitialize token_buttom just after using
11661 it as a watermark with obstack_free. Or else, a future token, big
11662 enough for triggering reallocation of the obstack chunk, could
11663 void the initialized value of token_buttom, later causing panic in
11664 obstack_free. Rename token_buttom to token_bottom everywhere.
11666 * m4.h: Before declaring errno, first include <errno.h> and
11667 ensure that it does not define errno.
11668 Reported by Richard Stallman.
11670 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
11672 * builtin.c: Define and use DECLARE macro for builtins.
11674 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
11675 argument, this is a common idiom for introducing long comments.
11677 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
11678 arguments. The last argument was silently ignored.
11680 * m4.c (cmd_error): Add a missing semicolon before va_end().
11682 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
11684 * Makefile.in: Now handle protoized sources. Define and use U.
11685 Compile and use ansi2knr with old compilers. Update DISTFILES.
11686 Add `aclocal.m4' to `configure' dependencies.
11687 * ansi2knr.c: New, from Ghostscript distribution.
11688 * configure.in: Define U through FP_PROTOTYPES for old compilers.
11689 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
11690 * aclocal.m4: New, provide FP_PROTOTYPES.
11691 * m4.h: Conditionnaly protoized through Args, save for varags.
11692 * builtin.c: Protoized. Then:
11693 Include <sys/types.h> if size_t is not defined, before "regex.h".
11694 (m4_ifelse): Fetch built-in name properly for diagnostic.
11695 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
11696 (m4_regexp): Add const to `msg' declaration.
11697 (m4_patsubst): Add const to `msg' declaration.
11698 * debug.c: Protoized, save for varargs.
11699 * eval.c: Protoized.
11700 * format.c: Protoized.
11701 * input.c: Protoized.
11702 * m4.c: Protoized, save for varargs. Then:
11703 (xfree): Accept void * instead of char *.
11704 (xmalloc): Return void * instead of char *.
11705 (xrealloc): Accept and return void * instead of char *.
11706 * macro.c: Protoized.
11707 * output.c: Protoized.
11708 * path.c: Protoized. Then cast some (char *) over xmalloc's.
11709 * symtab.c: Protoized.
11711 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
11713 * m4.texinfo: Remove directory from diagnostics in 30.include,
11714 51.eval, 56.errprint and 57.m4exit tests.
11716 * m4.h: Remove declarations for int or void system functions, they
11717 cause more conflicting trouble than they make good.
11719 * configure.in: Avoid configuration header file. Add some tests.
11720 * m4.h: Remove #include "config.h".
11721 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
11722 Then, rewritten for better compliance with GNU standards.
11724 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
11726 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
11727 because of a misplaced #endif.
11729 * Many *.[hc] files: Correct intra-line spacing here and there,
11730 according to GNU indent 1.6 advice.
11732 * configure.in: New, using Autoconf 1.2.

11736 Reported by Jason Merrill.
11738 * symtab.c (hash): Change (char) NULL to '\0'.
11739 Reported by Jason Merrill.
11741 * Delete .vers, etc/newdist.sh, etc/newvers.sh and
11742 etc/nextvers.sh. Release numbers will be edited `by hand'.
11743 * version.h: De-automatize, force value in.
11745 * m4.c: Changes in order to use a newer getopt.h.
11746 Reported by David MacKenzie.
11748 * checks/: New name for examples/.
11749 * checks/get_them: New location for etc/get_examples.
11750 * checks/check_them: New location for etc/check_examples.
11751 * Makefile.in, checks/get_them, checks/check_them: Adjust.
11752 * lib/vfprintf.c: New location for etc/vfprintf.c.
11753 * Delete empty etc/.
11754 * examples/: New name for test/.
11756 1992-03-10 François Pinard <pinard@iro.umontreal.ca>
11758 * Makefile.in (check): Add m4 as dependency.
11760 * m4.c: Accept --no-warnings instead of --no_warnings, and
11761 --no-gnu-extensions instead of --no_gnu_extensions. Make the
11762 usage message more informative.
11763 Reported by David MacKenzie.
11765 1992-03-09 François Pinard <pinard@iro.umontreal.ca>
11767 * etc/check_examples: New name for check_examples.sh.

11773 * Many *.[hc] files: GNU indent'ed, with further fine tuning of
11774 code disposition by hand.
11776 1992-03-08 François Pinard <pinard@iro.umontreal.ca>
11778 * m4.h: Delete definitions for abort() and exit().
11779 Reported by Richard Stallman.
11781 * config/hmake-unicos, config/s-unicos.h: New files.
11782 Reported by Hal Peterson.
11784 * eval.c (exp_term): Have N^0 return 1.
11785 Reported by Michael Fetterman.
11787 * eval.c, input.c, m4.h: Remove last comma in enums.
11788 Reported by Mike Lijewski.

11791 \f
11792 1991-10-24 René Seindal <seindal@diku.dk>
11794 * Release 1.0. Many thanks to those, who provided me with bug
11795 reports and feedback.
11797 * Uses GNU configure, taken from the gdb distribution.
11799 * Uses GNU getopt(), with long option names.
11801 * The -Q/+quiet option is added, which suppresses warnings about
11802 missing or superflous arguments to built-in macros.
11804 * Added default options via the M4OPTS environment variable.
11806 * The built-in format can now be configured to use sprintf as
11807 the formatting engine, for systems without [efg]cvt(3).
11809 * GNU library code is moved to the ./lib subdirectory; other
11810 utility files are now in ./etc.

11819 * The builtins incr and decr are now implemented without use of
11820 eval.
11822 * The builtin indir is added, to allow for indirect macro calls
11823 (allows use of "illegal" macro names).
11825 * The debugging and tracing facilities has been enhanced
11826 considerably. See the manual for details.
11828 * The -tMACRO option is added, marks MACRO for tracing as soon
11829 as it is defined.
11831 * Builtins are traced after renaming iff they were before.
11833 * Named files can now be undiverted.
11835 * The -Nnum option can be used to increase the number of
11836 divertions available.

11839 handling.
11841 * The function m4_patsubst() is now consistently declared
11842 static.
11844 * A bug in dnl is fixed.
11846 * A bug in the multi-character quoting code is fixed.
11848 * Several typos in the manual has been corrected. More probably
11849 persist.

11863 expressions.
11865 * Implemented builtin "patsubst" for substitution with regular
11866 expressions.
