1143 Stage 23: allow tracing of indirect macro calls.
1144 Track all trace information as part of the argv struct, rather
1145 than temporarily resetting global state. Teach indir to trace
1146 macros that it invokes.

1308 Stage 21b: $@ concatenates builtins, m4wrap takes builtins.
1309 Improve arg_print to handle builtin tokens when printing to a
1310 known chain, rather than always flattening builtins. This allows

1351 Speed impact: noticeable improvement, from fewer conditionals.
1352 * m4/input.c (eof_funcs, input_eof): New objects.
1353 (eof_peek, eof_read, eof_unget): New functions.
1354 (file_clean, m4_push_string_init, pop_input, m4_push_wrapup_init)
1355 (m4_pop_wrapup, next_char, peek_char, unget_input, m4_input_init)
1356 (m4_input_exit): Use placeholder to guarantee non-NULL isp and

1433 * m4/m4private.h (enum m4__symbol_chain_type): Add M4__CHAIN_LOC.
1434 (struct m4__symbol_chain): Add struct u_l.
1435 * m4/input.c (m4_push_wrapup_init, m4_push_wrapup_finish): Use
1436 new link type.
1437 (composite_peek, composite_read, composite_clean): Handle location
1438 link.
1439 * m4/macro.c (m4_wrap_args): New function.
1440 * modules/m4.c (m4wrap): Use it.
1441 * doc/m4.texinfo (M4wrap): Sync with branch and POSIX.
1442 (Extensions): Document extension of multiple arguments.
1443 (Location, Improved m4wrap): Adjust example to match FIFO order.
1444 * tests/builtins.at (wrap): Likewise.
1445 * NEWS: Document this change.
1447 2008-03-17 Eric Blake <ebb9@byu.net>
1449 Stage 20a: reduce unget's in input engine.
1450 Now that out-of-range input placeholders like CHAR_BUILTIN are
1451 consumed outside of next_char, next_token should always consume
1452 rather than peek at the first character. Fewer peeks results in
1453 less ungetc overhead.
1454 Memory impact: none.
1455 Speed impact: noticeable improvement, from fewer function calls.
1456 * m4/input.c (struct input_funcs): Alter read_func prototype.
1457 (next_char, file_read, buildin_read, string_read, composite_read):
1458 Add allow_argv parameter.
1459 (init_builtin_token, init_argv_symbol): Require all prior input to
1460 be consumed.
1461 (m4_skip_line, match_input, consume_syntax): Adjust callers.
1462 (m4__next_token): Consume first byte without peek.
1464 Update for fresh bootstrap.
1465 * ltdl/m4/gnulib-cache.m4: Updated copyright from upstream.
1467 2008-03-15 Eric Blake <ebb9@byu.net>
1469 Document join, in order to fix bug in m4wrap example.
1470 * examples/join.m4: New file.
1471 * examples/wraplifo2.m4: Likewise.
1472 * Makefile.am (EXTRA_DIST): Add new files.
1473 * doc/m4.texinfo (Improved m4wrap): New node.
1474 (Defn, Location): Enhance tests.
1475 (Shift): Document the composite macro join.
1476 (Incompatibilities): Move documentation of LIFO vs. FIFO...
1477 (M4wrap): ...here, to match improved example.
1479 2008-03-13 Eric Blake <ebb9@byu.net>
1481 Stage 19c: allow builtin tokens in more macros.
1482 Allow builtin tokens inside symbol chains, although for now, they
1483 are not allowed inside comments or quotes. Enable builtin token
1484 handling in more macros, if only to consistently diagnose invalid
1485 macro names.
1486 Memory impact: none.
1487 Speed impact: slight impact, due to more bookkeeping.
1488 * m4/m4module.h (m4_symbol_value_lookup, m4_builtin_print): New
1489 prototypes.
1490 * m4/m4private.h (enum m4__symbol_chain_type): Add
1491 M4__CHAIN_FUNC.

1497 (m4__push_symbol): Allow pushing builtin tokens.
1498 (composite_peek, composite_read, composite_unget, composite_clean)
1499 (composite_print): Handle builtin tokens.
1500 (init_builtin_token): Allow builtin tokens from composite input.
1501 (m4__next_token): Flatten builtins inside comment or string.
1502 * m4/macro.c (expand_argument): Strengthen assertion.
1503 (collect_arguments, m4_arg_equal, m4_arg_print, m4_push_args):
1504 Handle builtin tokens.
1505 (arg_symbol): Add parameter, and allow NULL level.
1506 (m4_arg_symbol, m4__push_arg_quote): Adjust callers.
1507 (m4_arg_text): Ensure all builtins have been flattened.
1508 * modules/m4.c (defn, dumpdef, popdef, traceoff, traceon)
1509 (undefine, m4_dump_symbols): Warn on invalid macro names.
1510 (ifdef, ifelse, shift): Handle builtin tokens.
1511 * modules/gnu.c (m4symbols): Likewise.
1512 * doc/m4.texinfo (Defn, Ifdef, Ifelse): Document and test the new
1513 behavior.
1514 (Debuglen): Likewise, and remove xfail.
1515 * NEWS: Mention the change.
1517 Stage 19b: invert sense of bit for handling builtin tokens.
1518 Pass builtin tokens by default, rather than as the exception, so
1519 that the logic can consistently refer to flattening arguments.
1520 Memory impact: none.
1521 Speed impact: none.
1522 * m4/m4module.h (M4BUILTIN_ENTRY): New convenience macro.
1523 (M4_BUILTIN_GROKS_MACRO): Rename...
1524 (M4_BUILTIN_FLATTEN_ARGS): ...and invert sense.
1525 (m4_symbol_value_groks_macro, m4_symbol_groks_macro): Likewise...
1526 (m4_symbol_value_flatten_args, m4_symbol_flatten_args): ...to
1527 this.
1528 * m4/m4private.h (VALUE_MACRO_ARGS_BIT)
1529 (m4_symbol_value_groks_macro): Likewise...
1530 (VALUE_FLATTEN_ARGS_BIT, m4_symbol_value_flatten_args): ...to
1531 this.
1532 * m4/symtab.c (m4_symbol_value_groks_macro): Likewise...
1533 (m4_symbol_value_flatten_args): ...to this.
1534 * m4/macro.c (collect_arguments): Accomodate changed sense.
1535 * m4/module.c (m4__module_open): Require arguments if flattening
1536 is requested.
1537 * m4/input.c (m4_push_string_finish): For now, flatten all
1538 builtins pushed as back-references.
1539 * modules/gnu.c (m4_builtin_table, builtin): Adjust all clients.
1540 * modules/import.c (m4_builtin_table): Likewise.
1541 * modules/load.c (m4_builtin_table): Likewise.
1542 * modules/modtest.c (m4_builtin_table): Likewise.

1545 * modules/shadow.c (m4_builtin_table): Likewise.
1546 * modules/stdlib.c (m4_builtin_table): Likewise.
1547 * modules/time.c (m4_builtin_table): Likewise.
1548 * modules/m4.c (m4_builtin_table): Likewise.
1549 (mkstemp): Undo #undef hack from 2006-10-23, now that macro names
1550 are stringized without preprocessor expansion.
1551 * doc/m4.texinfo (Defn): Update comments to match reality.
1552 (Debuglen): Update test now that user macros pass builtin tokens.
1554 Stage 19a: sort and cache builtins loaded by a module.
1555 Rather than repeatedly using dlsym to browse the builtin table,
1556 copy off the table at module load time. Then, the input engine
1557 merely refers to the copy instead of duplicating information.
1558 Memory impact: slight penalty, due to more memory per module, but
1559 offset by less memory in input engine.
1560 Speed impact: slight improvement, due to faster builtin lookups.
1561 * m4/m4module.h (m4_set_symbol_value_builtin): Delete. Use
1562 m4_builtin_find_by_* instead.
1563 (m4_builtin_find_by_func): Change return type.
1564 * m4/m4private.h (m4__builtin): New struct.
1565 (m4_module): Add sorted list of loaded builtins.
1566 (struct m4_symbol_value): Change type of builtin value.
1567 (m4__set_symbol_value_builtin): New prototype and fast accessor.
1568 (m4_get_symbol_value_func, m4_get_symbol_value_builtin): Adjust to
1569 new field type.
1570 * m4/symtab.c (m4_set_symbol_value_builtin): Rename...
1571 (m4__set_symbol_value_builtin): ...and populate additional fields,
1572 based on new type.
1573 (m4_get_symbol_value_func, m4_get_symbol_value_builtin): Adjust to
1574 new field type.
1575 * m4/module.c (install_builtin_table): Use cached table.
1576 (compare_builtin_CB): New helper function.
1577 (m4__module_open): Populate table.
1578 (module_remove): Free table.
1579 * m4/builtin.c (compare_builtin_name_CB): New helper function.
1580 (m4_builtin_find_by_name): Rewrite to use sorted table.
1581 (m4_builtin_find_by_func): Change return type.
1582 * m4/input.c (struct m4_input_block): Simplify u_b, since most
1583 fields can be determined from builtin.
1584 (builtin_peek, builtin_read, builtin_unget, init_builtin_token)
1585 (m4__next_token): Alter parsing so that only init_builtin_token
1586 consumes a builtin.
1587 (builtin_print, m4_push_builtin): Adjust all users.
1588 * tests/macros.at (Arity, defn, and freeze): Fix typo.
1590 Consistently cast malloc results, for C++ compilation.
1591 * m4/builtin.c (m4_builtin_find_by_name): Add cast.

1605 2008-03-06 Eric Blake <ebb9@byu.net>
1607 Fix nested builtin(`shift',$@) regression from 2008-02-23.
1608 * m4/macro.c (make_argv_ref): Don't output expansion text when
1609 making wrapper for builtin or indir.
1610 * tests/builtins.at (builtin): New test.
1611 * NEWS: Document the fix.
1612 Reported by Andreas Schwab.
1614 2008-03-04 Eric Blake <ebb9@byu.net>
1616 The gnulib module free was deprecated.
1617 * ltdl/m4/gnulib-cache.m4: Remove free module.
1619 2008-02-29 Eric Blake <ebb9@byu.net>
1621 Import news from 1.4.10b.
1622 * NEWS: Update from branch.
1624 2008-02-23 Eric Blake <ebb9@byu.net>
1626 Stage 18: try harder to reuse argv in recursion.
1627 When pushing arguments that contain an existing $@ ref, reuse the
1628 ref rather than creating another layer of wrappers.
1629 Memory impact: noticeable improvement, due to better $@ reuse.
1630 Speed impact: noticeable improvement, due to O(n^2) to O(n)
1631 reduction in unboxed recursion.
1632 * m4/macro.c (make_argv_ref): Avoid wrapping $@ when possible.
1633 (m4_push_args): Let make_argv_ref take care of pending data.
1634 * doc/m4.texinfo (Improved foreach): Tweak wording to match new
1635 performance capability.
1636 * tests/others.at (recursion): Add tests to avoid performance
1637 regression.
1639 2008-02-22 Eric Blake <ebb9@byu.net>
1641 Update NEWS.
1642 * NEWS: Document change to __gnu__ on 2008-02-11.
1644 Stage 17: pass argv through quoted strings.
1645 Allow the concatenation of $@ references with other text input
1646 inside quoted contexts, which requires distinguishing between a
1647 wrapper around many arguments vs. a reference serving as part of a
1648 single argument. Also optimize based on whether argv contains
1649 builtin tokens that might need flattening to the empty string.
1650 Memory impact: noticeable improvement, due to O(n^2) to O(n)
1651 reduction from total reuse of $@ references.
1652 Speed impact: noticeable improvement, due to O(n^2) to O(n)
1653 reduction in boxed recursion.
1654 * m4/m4module.h (m4_arg_equal, m4_arg_len): Add parameter.
1655 (M4ARGLEN): Adjust definition.
1656 * m4/m4private.h (struct m4__symbol_chain): Add has_func member.
1657 (struct m4_symbol_value): Add wrapper and has_func members.
1658 (struct m4_macro_args): Add flatten and has_func members.
1659 * m4/input.c (append_quote_token): Return argv refs inside quoted
1660 strings.
1661 (init_argv_symbol): Populate new fields.
1662 * m4/macro.c (expand_argument, collect_arguments, make_argv_ref)
1663 (m4_make_argv_ref): Likewise.
1664 (arg_symbol, arg_mark, m4_is_arg_text, m4_is_arg_func): Use new
1665 fields.
1666 (m4_arg_equal, m4_arg_len): Handle quoted argv references, and add
1667 new parameter.
1668 * modules/m4.c (ifelse): Adjust caller.
1670 2008-02-22 Gary V. Vaughan <gary@gnu.org>
1672 Fix regression in argument collection, from 2008-01-21.
1673 * m4/input.c (m4__next_token): When DEBUG_INPUT is defined,
1674 undo argument collection optimisation for strings, so that
1675 m4_print_token doesn't abort when it otherwise receives an
1676 unprintable M4_SYMBOL_VOID type token.
1678 2008-02-20 Eric Blake <ebb9@byu.net>
1680 Stage 16: cache quotes and improve m4_arg_print.
1681 Cache rather than always copying quotes when pushing $@ refs; in
1682 particular, reconstruct single-byte quotes on the fly. Allow NUL
1683 through m4wrap. Improve sharing of code that prints arguments.
1684 Memory impact: slight improvement, due to cached quotes.
1685 Speed impact: slight improvement, due to less copying.
1686 * m4/m4module.h (m4_symbol_value_print, m4_symbol_print)
1687 (m4_arg_print): Adjust prototypes.
1688 (m4_dump_args): Delete.
1689 (m4_push_wrapup): Split...
1690 (m4_push_wrapup_init, m4_push_wrapup_finish): ...into these
1691 prototypes.
1692 * m4/m4private.h (struct m4_syntax_table): Add cached_quote
1693 member.
1694 (m4__quote_cache, m4__quote_uncache): New prototypes.
1695 * m4/syntax.c (m4_syntax_create): Initialize the cache.
1696 (m4__quote_cache): New function.
1697 (m4_set_syntax): Update caller.
1698 * m4/symtab.c (m4_symbol_value_print): Add parameter.
1699 (m4_symbol_print, dump_symbol_CB): Adjust all callers.
1700 * m4/utility.c (m4_dump_args): Delete; callers should use
1701 m4_arg_print instead.
1702 * m4/input.c (m4_push_wrapup_init, m4_push_wrapup_finish): Split
1703 implementation, and allow embedded NUL.
1704 (m4_print_token, pop_input, composite_print, composite_peek):
1705 (composite_read, append_quote_token): Adjust all callers.
1706 * m4/macro.c (trace_prepre, m4_arg_text, make_argv_ref):
1707 Likewise.
1708 (m4_arg_print): Add parameters.
1709 (trace_pre): Rewrite in terms of m4_arg_print.
1710 * modules/m4.c (errprint): Likewise.

1717 Fix out-of-bounds read for sanitized macro names, from 2008-02-06.
1718 * m4/utility.c (m4_verror_at_line): Properly terminate the string.
1719 Reported by Ralf Wildenhues.
1721 * doc/m4.texinfo (Debuglen, Changesyntax): Fix typos.
1723 2008-02-19 Eric Blake <ebb9@byu.net>
1725 Clean up example on filtering defined symbols.
1726 * doc/m4.texinfo (Foreach, Improved foreach): Document another
1727 shortcoming in foreach.m4, and improve filter example by using
1728 foreach2.m4.
1730 * src/main.c (usage): Fix typo.
1732 2008-02-18 Eric Blake <ebb9@byu.net>
1734 Avoid some magic numbers.
1735 * m4/m4private.h (CHAR_EOF, CHAR_BUILTIN, CHAR_QUOTE, CHAR_ARGV)
1736 (CHAR_RETRY): Define in terms of UCHAR_MAX.
1737 * m4/syntax.c (m4_syntax_create, set_syntax_set)
1738 (reset_syntax_set, check_is_single_quotes)

1752 * examples/hanoi.m4: Likewise.
1753 * examples/trace.m4: Likewise.
1754 * doc/m4.texinfo (Improved forloop): Document advantage of $0.
1755 (Improved foreach): Adjust dump from file.
1757 Stage 15: return argv refs back to collect_arguments.
1758 Collect an entire $@ reference at once rather than one argument at
1759 a time, outside of quotes (but inside quotes, $@ is still
1760 flattened for now). The skip_last field allows concatenation of
1761 $@ with other text when collecting arguments.
1762 Memory impact: noticeable improvement, due to better reuse of $@.
1763 Speed impact: noticeable improvement, due to less parsing.
1764 * m4/m4private.h (CHAR_ARGV): New input engine sentinel.
1765 (enum m4__token_type): Add M4_TOKEN_ARGV.
1766 (struct m4__symbol_chain): Add skip_last member to argv link.

1775 (arg_mark, m4_arg_text, make_argv_ref): Likewise.
1776 (expand_argument, collect_arguments): Handle new token.
1777 (arg_symbol): Drill through $@ reference.
1778 * m4/syntax.c (set_quote_age): Detect disabled comments.
1779 * m4/symtab.c (dump_symbol_CB) [DEBUG_SYM]: Fix debug code.
1781 2008-02-15 Eric Blake <ebb9@byu.net>
1783 * modules/gnu.c (regexp_compile): Use a fastmap for regex speed.
1785 2008-02-13 Eric Blake <ebb9@byu.net>
1787 Fix texinfo grammar.
1788 * doc/m4.texinfo (Eval, Incompatibilities): Use @. after capital.
1789 (History): Use @: after abbreviations.
1790 (M4exit): Use correct Latin abbreviation.
1791 (Dumpdef, Debugmode, Frozen file format 2): Use correct spacing
1792 between sentences.
1794 2008-02-11 Eric Blake <ebb9@byu.net>
1796 Allow builtin text macros to specify number of arguments.
1797 * m4/m4module.h (struct m4_macro): Add argument limits to builtin
1798 text macros.

1864 Stage 14b: allow pushing argv references.
1865 Push a $@ reference to the input engine in one go, rather than
1866 pushing each element. For now, argument collection still gets one
1867 argument of a $@ at a time; but the penalties of this patch make
1868 it easier to manage $@ efficiently in future patches.
1869 Memory impact: noticeable penalty, due to larger struct and O(n)
1870 to O(n^2) on unboxed recursion.
1871 Speed impact: noticeable penalty, due to more bookkeeping.
1872 * m4/m4private.h (struct m4__symbol_chain): Add comma and quotes
1873 fields.

1952 2008-01-27 Eric Blake <ebb9@byu.net>
1954 Stage 13: push composite text tokens.
1955 Support pushing composite tokens, allowing back-references to be
1956 reused through multiple macro expansions. Add hueristic that
1957 avoids creating new reference when pushing existing references.
1958 Memory impact: noticeable improvement due to better reference
1959 reuse, except for O(n) to O(n^2) copying in boxed recursion.
1960 Speed impact: slight penalty, due to more bookkeeping.

2061 Stage 11: full circle for single argument references.
2062 Pass quoted strings through to argument collection in a single
2063 action, so that an argument can be reused throughout macro
2064 recursion if it remains unchanged.
2065 Memory impact: noticeable improvement, due to more reuse in
2066 argument collection stacks; O(n^2) to O(n) on boxed recursion.
2067 Speed impact: noticeable improvement, due to less copying.
2068 * m4/m4module.h (m4_arg_text): Add parameter.

2088 * m4/macro.c (expand_argument): Collect composite arguments.
2089 (collect_arguments): Update new field.
2090 (expand_macro): Reduce ref-count of back-references after use.
2091 (arg_mark, m4_arg_symbol, m4_make_argv_ref): Adjust to new member
2092 names.
2093 (m4_is_arg_text): Also recognize composite symbols as text.
2094 (m4_arg_text, m4_arg_len): Merge composite symbols as needed.
2095 (m4_arg_equal): Compare composite symbols.
2096 (m4_push_arg, m4_push_args): Handle composite symbols.

2099 * m4/output.c (m4_shipout_string_trunc): Update comment.
2100 * tests/macros.at (Rescanning macros): Augment test.
2102 2008-01-16 Eric Blake <ebb9@byu.net>
2104 Stage 10: avoid extra copying of strings and comments.
2105 When collecting tokens that are immune to further expansion, avoid
2106 copying data from one obstack to another by outputting it into the
2107 destination obstack to begin with. Also reduce copying done in
2108 format builtin.
2109 Memory impact: slight improvement, due to better obstack usage.
2110 Speed impact: noticeable improvement, due less data copying.
2111 * ltdl/m4/gnulib-cache.m4: Import intprops and vasnprintf-posix
2112 modules.
2113 * m4/m4private.h (m4__token_type): Adjust prototype.
2114 * m4/input.c (m4__next_token): Support new parameter.
2115 * m4/macro.c (m4_macro_expand_input, expand_token)
2116 (expand_argument, collect_arguments): Adjust callers.
2117 * modules/m4.c (ntoa): Tighten buffer size.
2118 * m4/output.c (m4_tmpname): Guarantee no buffer overflow.
2119 * modules/format.c (arg_int, arg_long, arg_double): New helper
2120 functions, to detect overflow or unparsed characters.
2121 (ARG_INT, ARG_LONG, ARG_STR, ARG_DOUBLE): Adjust to check for
2122 missing or excess arguments.
2123 (format): Likewise, and also output directly into obstack if there
2124 is room.
2125 * doc/m4.texinfo (History): Update for new year.
2126 (Format): Test for new warnings.
2128 2008-01-15 Eric Blake <ebb9@byu.net>
2130 * TODO: Update with some newer URLs.
2132 Verify linear `index'.
2133 * tests/builtins.at (index): New test.
2134 (translit): Make test take longer, to make quadratic algorithms
2135 more apparent.
2137 2007-12-20 Eric Blake <ebb9@byu.net>
2139 Stage 9: share rather than copy single-arg refs.
2140 Use hooks of previous patch to create back-references to arguments
2141 in the input engine, and inline short text rather than always
2142 creating a FIFO link. Also start testing embedded NUL behavior.
2143 Until the argument collection engine also shares references, the
2144 memory usage increases.
2145 Memory impact: noticeable penalty, due to longer life of argv
2146 changing O(n) to O(n^2) on boxed recursion.
2147 Speed impact: slight improvement, due less data copying.
2148 * ltdl/m4/gnulib-cache.m4: Import memmem and quote modules.
2149 * m4/m4module.h (m4_arg_scratch): New prototype.
2150 * m4/m4private.h (m4__push_symbol): Add parameter.
2151 (m4_arg_scratch): Add fast accessor.
2152 (struct m4): Add expansion_level member, taken...
2153 * m4/macro.c (expansion_level): ...from here. Adjust all users.
2154 (expand_argument): Minor cleanup.
2155 (expand_macro): Track scratch space per macro call.
2156 (m4_arg_scratch): New function.
2157 (m4_make_argv_ref): Call new function.
2158 (m4_push_arg): Push reference to $0.
2159 (m4_push_args): Rework separator usage, since separators will
2160 usually be inlined.
2161 (process_macro): Allow embedded NUL.
2162 * m4/input.c (INPUT_INLINE_THRESHOLD): New define.
2163 (m4__push_symbol): Add parameter. Inline short strings, and save
2164 references through rescanning.
2165 * m4/symtab.c (m4_set_symbol_value_text): Weaken assertion.
2166 * modules/m4.c (errprint, index): Handle NUL transparently.
2167 (dumpdef, translit): Use scratch space, rather than expansion
2168 stack.
2169 * modules/gnu.c (renamesyms, m4symbols): Likewise.
2170 * tests/others.at (nul character): New test.
2171 (iso8859): Quote absolute file name, remove XFAIL.
2172 * tests/iso8859.m4: Avoid raw NUL in output.
2173 * tests/null.m4: New file.
2174 * tests/null.out: Likewise.
2175 * tests/null.err: Likewise.
2176 * Makefile.am (OTHER_FILES): Distribute new files.
2177 * .gitattributes: Treat new files as text.
2179 2007-12-17 Eric Blake <ebb9@byu.net>
2181 Stage 8: extend life of references into argv.
2182 Add hooks to lengthen the lifetime of arguments reused in a macro
2183 expansion, rather than always discarding arguments at the end of
2184 expand_macro. Rework the expand_macro obstacks to handle longer
2185 lifetimes. For now, the hooks remain unused.
2186 Memory impact: slight penalty, due to larger structs.
2187 Speed impact: slight penalty, due to more bookkeeping.
2188 * m4/system_.h (obstack_regrow): Delete.
2189 * m4/m4private.h (struct m4_symbol_chain): Add level field.
2190 (m4__push_symbol): Adjust prototype.
2191 (m4__adjust_refcount): New prototype.
2192 (DEBUG_MACRO) [DEBUG]: New debug control.
2193 (struct m4__macro_arg_stacks): New structure.
2194 (struct m4): Add arg_stacks, stacks_count fields.
2195 * m4/m4module.h (m4_make_argv_ref): Add parameter.
2196 * m4/macro.c (argc_stack, argv_stack): Delete, replaced by
2197 context->arg_stacks.
2198 (m4_macro_expand_input) [DEBUG_MACRO]: Add debug hooks,
2199 conditional on M4_DEBUG_MACRO envvar.
2200 (collect_arguments): Adjust signature.
2201 (expand_macro): Rework obstack handling.
2202 (m4__adjust_refcount, arg_mark): New functions.
2203 (m4_make_argv_ref): Populate new field.
2204 (m4_push_arg, m4_push_args): Track inuse.
2205 (process_macro): One less cast.
2206 * m4/m4.c (m4_delete): Clean up arg_stacks.
2207 * m4/input.c (make_text_link): Use new field.
2208 (m4__push_symbol, file_clean): Update signature.
2209 (composite_read): Bump refcount when done with reference.
2210 (composite_clean): New function.
2211 (pop_input): Adjust caller.
2212 * m4/debug.c (m4_debug_message): Make assertion match comment.
2213 * modules/gnu.c (builtin, indir): Adjust callers.
2214 * tests/builtins.at (ifelse): New test.
2215 (exp): Move and rename...
2216 * tests/others.at (countdown): ...to this.
2217 * doc/m4.texinfo (Improved foreach): Fix tracing usage in
2218 example.
2220 2007-12-13 Eric Blake <ebb9@byu.net>
2222 Yet more rewording.
2223 * doc/m4.texinfo (Inhibiting Invocation): Missed one instance in
2224 the previous patch.
2226 * THANKS: Update.
2228 2007-12-13 Paolo Bonzini <bonzini@gnu.org> (tiny change)
2230 * doc/m4.texinfo (Inhibiting Invocation): Fix quoting of a quoting
2231 example.
2232 Reported by Giovanni Toffetti.
2234 2007-12-11 Eric Blake <ebb9@byu.net>
2236 Stage 7: use chained input support in input parser.
2237 Allow the LIFO input engine to rescan a macro expansion composed
2238 of smaller chunks of FIFO data, rather than the old approach of a
2239 monolithic string. For now, all chunks are still copied.
2240 Memory impact: slight penalty, due to FIFO chain overhead.
2241 Speed impact: slight penalty, due to extra bookkeeping.
2242 * m4/m4private.h (m4__push_symbol): New prototype.
2243 (struct m4_symbol_chain): Add const-safety.
2244 * m4/symtab.c (m4_symbol_value_print): Simplify.
2245 (dump_symbol_CB): Update caller.
2246 * m4/input.c (struct m4_input_block): Alter u_c member, first
2247 introduced 2006-10-25, but unused until now.
2248 (composite_peek, composite_read, composite_unget)
2249 (composite_print, init_builtin_token): Rewrite accordingly.
2250 (m4_push_wrapup): No longer need trailing NUL.
2251 (m4__push_symbol, make_text_link): New functions.
2252 (m4_push_string_finish): Use them.
2253 * m4/macro.c (m4_push_arg, m4_push_args): Likewise.
2254 (expand_macro): Simplify logic of nesting_limit.
2255 * src/main.c (main): Likewise.
2256 * doc/m4.texinfo (Dumpdef): Augment test.
2258 2007-12-08 Eric Blake <ebb9@byu.net>
2260 Stage 6: convert builtins to push arg at a time.
2261 Add new methods to factor all builtins whose expansion includes an
2262 argument, making back-reference creation easier in future patches.
2263 Factor out length-limited printing to obstacks, and use -1 rather
2264 than 0 for unlimited length.
2265 Memory impact: none.
2266 Speed impact: slight improvement, due to better code sharing.
2267 * m4/m4module.h (m4_shipout_text): Rename...
2268 (m4_divert_text): ...to this, to avoid confusion with m4_shipout_*
2269 that does not worry about sync lines.
2270 (m4_shipout_string_trunc): New prototype.
2271 * m4/output.c (m4_shipout_text): Rename...
2272 (m4_divert_text): ...to this.
2273 (m4_shipout_string): Move guts...
2274 (m4_shipout_string_trunc): ...to this new function.
2275 * m4/macro.c (m4_push_arg, m4_push_args): New functions.
2276 (expand_token, process_macro): Update callers.
2277 * m4/input.c (string_print): Likewise.
2278 * modules/m4.c (ifdef, ifelse, shift, substr, translit, divert):
2279 Likewise.
2280 * modules/gnu.c (patsubst): Likewise.
2281 (debuglen): Use SIZE_MAX for unlimited debug length.
2282 * src/main.c (main): Likewise.
2283 * m4/m4.c (m4_create): Default max_debug_length to SIZE_MAX, not
2284 zero.
2286 2007-12-07 Eric Blake <ebb9@byu.net>
2288 Minor security fix: Quote output of mkstemp.
2289 * modules/m4.c (m4_make_temp): Produce quoted output.
2290 * doc/m4.texinfo (Mkstemp, Mkdtemp): Update the documentation and
2291 tests.
2293 Stage 5: add notion of quote age.
2294 Cache the quoting rules that were in effect when a string was
2295 parsed, to avoid reparsing that string if no changequote or other
2296 quote age change took place in the meantime. A quote_age of 0 is
2297 always safe, but does not benefit from caching.
2298 Memory impact: slight improvement, due to smaller struct in input
2299 engine.
2300 Speed impact: slight penalty, due to more bookkeeping.
2301 * m4/m4module.h (m4_get_symbol_value_quote_age): New prototype.

2309 member.
2310 (m4_set_symbol_value_text): Adjust fast accessor.

2316 (expand_argument, collect_arguments): Track quote age.
2317 (m4_macro_expand_input, process_macro, m4_make_argv_ref)
2318 (m4_macro_expand_input): Update callers.
2319 (m4_arg_text, m4_arg_len, m4_arg_func): Abort on type mismatch.
2320 * m4/input.c: Comment cleanups.
2321 (struct m4_input_block): Reduce size.
2322 (m4__next_token): Report quote age.
2323 (m4_push_builtin, init_builtin_token): Update callers.

2336 * examples/wrapfifo.m4: New file.
2337 * examples/wraplifo.m4: New file.
2338 * Makefile.am (dist_pkgdata_DATA): Distribute new examples.
2340 2007-12-04 Eric Blake <ebb9@byu.net>
2342 Fix builds with OpenBSD make.
2343 * Makefile.am (HELP2MAN): New macro.
2344 (dist_man_MANS, doc/m4.1): Fix rules for building m4.1 into
2345 srcdir.
2346 * README: Update copyright.
2347 * HACKING: Mention help2man and makeinfo dependencies.
2349 2007-11-29 Eric Blake <ebb9@byu.net>
2351 Stage 4: route indir, builtin through ref; make argv opaque.
2352 Finish making struct opaque to all but the input engine, by
2353 reworking obstack usage in expand_macro to better support creation
2354 of a $@ reference. Canonicalize the empty argument, to allow
2355 pointer comparison optimizations.
2356 Memory impact: slight penalty, due to larger struct.
2357 Speed impact: slight improvement, due to fewer function calls.
2358 * m4/system_.h (obstack_regrow): Fix precedence.
2359 * m4/m4module.h (m4_arg_equal, m4_arg_empty, m4_make_argv_ref):
2360 New prototypes.
2361 (struct m4_macro_args): Move...
2362 * m4/m4private.h (struct m4_macro_args): ...here, making it opaque
2363 to modules. Add has_ref member.
2364 (bool_bitfield): New helper typedef.
2365 (struct m4_symbol_chain): Add flatten and len members.
2366 * m4/macro.c (empty_symbol): New placeholder, for optimizing
2367 comparison with empty string.
2368 (m4_macro_expand_input): Initialize it.
2369 (collect_arguments): Alter signature, and populate new fields.
2370 (trace_pre, trace_post): Remove redundant parameter.
2371 (expand_macro): Alter handling of obstacks.

2379 methods.
2380 (changesyntax, regexp): Optimize.
2381 * m4/output.c (diversion_storage): Use typedef.
2383 Stage 3b: cache length, rather than computing it, in modules.
2384 Use cached token length in builtins and output engine.
2385 Memory impact: none.
2386 Speed impact: noticeable improvement, due to fewer function calls.
2387 * m4/hash.c (m4_hash_remove): Avoid double free on remove
2388 failure.
2389 * m4/output.c (m4_shipout_string): Change semantics of len param.
2390 (m4_shipout_int): Use cached length.
2391 * m4/input.c (m4_push_string_finish): Likewise.
2392 * modules/m4.h (m4_make_temp_func): Add parameter.
2393 * m4/macro.c (expand_token, m4_arg_len): Use cached length.
2394 (collect_arguments, expand_macro): Alter signature.

2400 (m4symbols, mkdtemp, regexp_compile, regexp_substitute,
2401 renamesyms, patsubst, regexp, regexp_compile): Likewise.
2402 * modules/load.c (m4modules): Likewise.
2403 * modules/m4.c (defn, m4wrap, maketemp, m4_make_temp)

2411 * tests/builtins.at (mkstemp): Likewise.
2412 * tests/others.at (iso8859): XFAIL this test, now that
2413 length-based handling allows NUL through part but not all of M4.
2415 2007-11-28 Eric Blake <ebb9@byu.net>
2417 Stage 3a: cache length, rather than computing it, in libm4.
2418 Cache the length of a token in the input engine and symbol table,
2419 to avoid repeating lots of strlen calls. Additionally, by using
2420 obstack length rather than strlen, the input engine can now
2421 support embedded NUL.
2422 Memory impact: slight penalty, due to larger struct.
2423 Speed impact: slight improvement, due to fewer function calls.
2424 * m4/m4module.h (struct m4_macro_args): Cache length.
2425 (m4_get_symbol_len, m4_get_symbol_value_len): New accessors.

2434 (m4_push_wrapup): Track length of string input.
2435 (m4__next_token): Adjust all users of symbol text to track length,
2436 too.
2437 * m4/macro.c (expand_argument, collect_arguments): Likewise.
2438 * m4/module.c (install_macro_table): Likewise.
2439 * modules/gnu.c (builtin, indir): Likewise.

2447 Adjust implementation.
2449 2007-11-27 Eric Blake <ebb9@byu.net>
2451 Stage 2: use accessors, not direct reference, into argv.
2452 Outside of macro.c, use accessor methods rather than direct access
2453 into the argv struct.
2454 Memory impact: none.
2455 Speed impact: slight penalty, due to increased function calls.
2456 * m4/m4private.h (m4_arg_argc): New fast accessor.
2457 * m4/m4module.h (m4_arg_argc, m4_arg_symbol, m4_is_arg_text)

2459 prototypes.
2460 (m4_builtin_func, M4BUILTIN, M4BUILTIN_HANDLER, m4_dump_args)
2461 (m4_macro_call): Make argc unsigned.
2462 (M4ARG): Use new accessors.
2463 * modules/m4.c (define, pushdef): Likewise.
2464 (undefine, popdef, ifelse, m4_dump_symbols, defn, undivert)

2475 (expand_macro, trace_pre, trace_post, m4_macro_call): Update argc
2476 usage.
2478 2007-11-24 Eric Blake <ebb9@byu.net>
2480 Stage 1: convert m4_symbol_value** into new object.
2481 Pass a variable-size wrapper structure instead of an array to
2482 builtins, so that subsequent optimizations in the structure need
2483 not impact every builtin client.
2484 Memory impact: slight penalty, since struct is larger than array.
2485 Speed impact: slight penalty, due to increased bookkeeping.
2486 * ltdl/m4/gnulib-cache.m4: Import flexmember module.
2487 * m4/m4module.h (m4_macro_args): New type, will be opaque to
2488 modules later.
2489 (m4_builtin_func, M4BUILTIN, M4BUILTIN_HANDLER, m4_dump_args)

2552 2007-11-14 Eric Blake <ebb9@byu.net>
2554 Handle some defn corner cases differently.
2555 * doc/m4.texinfo (Defn): Update documentation; although this still
2556 doesn't match the branch, since it may be changed before 2.0.
2557 * m4/macro.c (expand_argument): Consistently ignore builtins in
2558 concatenation contexts.
2559 * m4/m4private.h (m4__symbol_type): Fix C89 compliance bug.
2561 2007-11-13 Eric Blake <ebb9@byu.net>
2563 Note: Patches titled Stage 0 through N form a series of patches
2564 which decreases the algorithmic complexity of tail recursion in
2565 macro expansions from O(n^2) to O(n) in both time and memory, then
2566 performs cleanups, such as handling of embedded NUL, made easier
2567 by the code refactoring.
2569 Stage 0: Fix memory leak in tail recursion.
2570 Free expansion text in the input engine as soon as it is parsed,
2571 rather than when the recursive expansion completes.
2572 Memory impact: noticeable improvement, due to reduction from
2573 O(n^2) to O(n) on recursion.

3265 M4 was designed to have a small number of header files defining
3266 the interfaces to several source files each. Keeping this in
3267 mind allows us to tidy things up considerably. Having done this,
3268 it becomes clear that some of the installed headers reference

5374 elsewhere.

5424 (M4_DEFAULT_PRELOAD): Use as a macro, not shell variable.
5425 * Makefile.am (src_m4_CPPFLAGS): Use STACKOVF as a makefile
5426 conditional.
5427 * ltdl/m4/m4-gnulib.m4: Delete, no longer needed.
5429 Reduce compiler warnings. Inside GMP, mpq_t is an array type, so
5430 const mpq_t is not assignable from plain mpq_t. Avoid
5431 type-punning warnings caused trying to mix these types.
5432 * modules/mpeval.c (numb_ior, numb_eor, numb_and, numb_lshift),
5433 (numb_rshift, numb_divide, numb_modulo): Remove const qualifier.
5434 * modules/evalparse.c (or_term, xor_term, and_term, shift_term),
5435 (mult_term, exp_term): Remove type-punning casts.
5436 (numb_pow): Remove const qualifier.
5437 * src/freeze.c (reload_frozen_state): Fix typo in messages.
5438 Fix variables that can be used uninitialized, which fixes
5439 security hole where malicious frozen file can execute arbitrary
5440 code.
5442 2006-06-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5444 * Makefile.am (modules_mpeval_la_LIBADD): Readd $(LIBADD_GMP).

5447 and Eric Blake <ebb9@byu.net>
5449 Allow `make dist' to work again.
5450 * Makefile.am (EXTRA_DIST): doc/helptoman.pl is gone.
5451 (MAINTAINERCLEANFILES): Avoid redundant mention of dist_man_MANS.
5452 (cvs-dist): Fix typo.
5453 * NEWS: Match current version number.
5455 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5457 * Makefile.am (AM_CPPFLAGS): Add $(LTDLINCL), so the right
5458 ltdl.h is used.
5460 * bootstrap: Do not run libtoolize manually, this is done
5461 correctly by autoreconf. Invoke autoreconf with --no-recursive
5462 to avoid unnecessary rerunning of autotools for libltdl.
5464 2006-06-13 Eric Blake <ebb9@byu.net>
5466 * THANKS: Update.
5468 2006-06-12 Eric Blake <ebb9@byu.net>
5470 * m4/output.c [HAVE_MKTEMP]: Gnulib provides mkstemp, so don't
5471 bother with mktemp.
5472 * src/m4.h: Don't declare mktemp.
5473 * m4/input.c (m4__next_token): Avoid bzero.
5474 * configure.ac (AC_CHECK_FUNCS): Remove obsolete checks.
5475 * Makefile.am (doc/m4.1): Depend on installed help2man, rather
5476 than distributing outdated helptoman.pl.
5477 * doc/helptoman.pl: Delete.
5479 2006-06-10 Eric Blake <ebb9@byu.net>
5481 * README (Patches): Document the current dependence on CVS
5482 builds of autotools.
5483 * ltdl/m4/gnulib-cache.m4: Update, and use --macro-prefix=M4.
5484 * configure.ac: Use consistent quoting throughout.
5485 (AC_PREREQ): Bump to 2.59d.
5486 (AC_INIT): Package name begins with uppercase.
5487 (AC_ARG_WITH): Use AS_HELP_STRING.
5488 (AM_INIT_AUTOMAKE): Enable gnits mode.
5489 (AC_ISC_POSIX, AM_PROG_CC_STDC, AC_PROG_INSTALL, AC_PROG_MAKE_SET),
5490 (AC_PROG_AWK, AM_C_PROTOTYPES, AC_C_CONST, AC_HEADER_STDC),
5491 (AC_CHECK_HEADERS, AC_FUNC_ALLOCA, AC_FUNC_VPRINTF): Remove checks
5492 done by gnulib or automake, or which autoconf has declared
5493 obsolete.
5494 * m4/m4private.h (Includes): Assume C89 or better, and use errno
5495 unconditionally.
5496 * m4/output.c (Includes): Likewise.
5497 * modules/gnu.c (Includes): Likewise.
5498 * modules/m4.c (Includes): Likewise.
5499 * src/m4.h (Includes): Likewise.

5503 about cygwin. Document bootstrapping dependency.
5504 * AUTHORS: Update from branch-1_4.
5505 * THANKS: Likewise. Change encoding to UTF-8.
5506 * BACKLOG: Delete. This file is too old and unmaintained to be
5507 worthwhile.
5508 * ChangeLog: Change encoding to UTF-8.
5510 Avoid compiler warnings.
5511 * m4/macro.c (trace_format): Don't mark this as a printf format,
5512 since we don't accept the same set of modifiers as printf. It
5513 would be nice if gcc let us specify a custom format archetype.
5514 * src/main.c (main): Cast away const.
5516 2006-06-10 Andreas Schwab <schwab@suse.de> (tiny change)
5517 Eric Blake <ebb9@byu.net>

5521 (gmtime): Likewise.
5522 (localtime): Likewise.
5523 (strftime): Likewise.
5524 * m4/utility.c (m4_numeric_arg): For now, document arbitrary
5525 limit inherent in this interface.
5527 2006-05-08 Bruno Haible <bruno@clisp.org> (tiny change)
5529 * modules/m4.c (WEXITSTATUS): Provide fallback definition.
5530 (sysval): Use WEXITSTATUS.
5531 * modules/gnu.c (esyscmd): Set sysval to 0xffff, to accomodate both
5532 big-endian and little-endian wait status definitions.
5534 2006-05-06 Eric Blake <ebb9@byu.net>
5536 * po/Makevars (MSGID_BUGS_ADDRESS): Add.
5537 * po/POTFILES.in (src/getopt.c, src/version-etc.c): These files live
5538 in src, not gnu.
5540 2006-05-06 Eric Blake <ebb9@byu.net>
5542 * configure.ac (LT_CONFIG_LTDL_DIR): Inform libtool which
5543 subdirectory to use.
5544 (support for -pipe): Move after LT_INIT, since it relies on
5545 libtool internals.
5547 2006-05-05 Eric Blake <ebb9@byu.net>
5549 * Makefile.am (doc/m4.1): Use $@, not $(srcdir)/doc/$@.
5551 * THANKS: Update.
5553 2006-05-05 Bruno Haible <bruno@clisp.org>
5554 and Eric Blake <ebb9@byu.net>
5556 * configure.ac (gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES): Move to...

5564 Cleanup whitespace.
5566 2005-12-05 Gary V. Vaughan <gary@gnu.org>
5568 * bootstrap (func_update_po): Synch with CVS GNU tar. wget 1.9.x
5569 and 1.10.x support --cache=off, so $WGETFLAGS are not necessary.
5570 Reported by Eric Blake <ebb9@byu.net>
5572 2005-12-04 Gary V. Vaughan <gary@gnu.org>
5574 * bootstrap (func_update_po): Test and set $WGETFLAGS to disable
5575 http caching as -C is no longer supported by wget 1.10.x.
5576 Reported by Eric Blake <ebb9@byu.net>
5578 2005-10-20 Gary V. Vaughan <gary@gnu.org>
5580 * m4/module.c (caller_id): To match libtool-2.0 interface, changed
5581 to ...
5582 (iface_id): ...an lt_dlinterface_id type.
5583 (m4__module_find): New abstraction for lt_dlhandle_fetch. Use
5584 throughout, instead of calling obsolete lt_dlhandle_find directly.
5585 (m4__module_next): Use multiloader-safe lt_dlhandle_iterate. Use
5586 throughout, instead of calling obsolete lt_dlhandle_next.
5587 * m4/m4private.h (m4__module_find): Declare it.
5588 * m4/builtin.c (m4_builtin_find_by_name, m4_builtin_find_by_func):
5589 Use m4__module_next instead of obsolete lt_dlhandle_next.
5591 2005-10-20 Gary V. Vaughan <gary@gnu.org>
5593 * bootstrap (func_update_po): Update pofiles directly from the
5594 translation project.
5595 * po/LINGUAS, po/cs.po, po/de.po, po/el.po, po/fr.po, po/it.po,
5596 po/ja.po, po/nl.po, po/pl.po, po/ru.po, po/sv.po: No need to store
5597 these files under source control anymore.
5598 Suggested by Eric Blake <ebb9@byu.net>
5600 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
5602 * ltdl/m4/m4-gnulib.m4: Update FSF contact address. Somehow this
5603 file escaped the address updates on 2005-05-01.
5605 2005-07-07 Gary V. Vaughan <gary@gnu.org>
5607 * bootstrap: Allow user overriding of gnulib-tool location, and
5608 correctly determine module source directories whether gnulib-tool
5609 is given as a relative or absolute path, or is found by searching
5610 PATH.
5611 Reported by Eric Blake <ebb9@byu.net>
5613 2005-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5615 * ltdl/m4/debug.m4 (m4_CHECK_DEBUGGING): Make sure that both $rm
5616 and $RM are defined for various versions of
5617 AC_LIBTOOL_COMPILER_OPTION.
5619 * bootstrap (AUTORECONF): New variable to allow user overriding of
5620 autoreconf path.
5622 2005-07-07 Gary V. Vaughan <gary@gnu.org>
5624 * doc/m4.texinfo (History): Add better notes on the ancestory of
5625 GNU m4, and other historical interest.
5627 2005-05-08 Gary V. Vaughan <gary@gnu.org>
5629 * m4/symtab.c (m4_symbol_rename): New function that performs a low
5630 level symbol rename.
5631 * m4/m4module.h (m4_symbol_rename): Declare it as part of the API.
5632 * modules/gnu.c (regsub): Factored out of m4_epatsubst_do...
5633 (m4_patsubst_do, m4_renamesyms_do): ...wrappers that use
5634 regsub...
5635 (erenamesyms, renamesyms): ...builtins that use these to implement
5636 macro renaming by regular expression.
5637 * doc/m4.texinfo (Erenamesyms and Renamesyms): Document them.
5638 * tests/generate.awk: Allow some forbidden `m4_' prefixed symbols
5639 to stop the new generated tests from choking.
5641 2005-05-07 Gary V. Vaughan <gary@gnu.org>
5643 Since most of the build is handled from a single Makefile.am now,
5644 we can teach make about the dependencies between the m4 binary and
5645 the preopened modules it is built against:
5647 * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
5648 preopened modules.
5649 * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
5650 of the preopened modules have changed.
5652 2005-05-07 Gary V. Vaughan <gary@gnu.org>
5654 * configure.ac (gl_MODULES): Add mkstemp for machines that don't
5655 have a native implementation.
5657 2005-05-06 Gary V. Vaughan <gary@gnu.org>
5659 * src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are
5660 handled already by gnu/exit.h.
5662 * configure.ac (gl_MODULES): Add assert to support a
5663 --disable-assert configure time option for NDEBUG setting.
5665 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.
5666 * bootstrap (src_modules): Add version-etc-fsf.
5667 * src/main.c (version_etc_copyright): Removed.
5669 * ltdl/m4/m4-getopt.m4 (m4_GETOPT): Synch with gnulib/getopt.m4.
5671 2005-05-04 Gary V. Vaughan <gary@gnu.org>
5673 * src/m4.h (__CYGWIN__, WIN32): Canonicalise Windows and Cygwin
5674 recognition macros.
5675 * src/freeze.c (produce_frozen_state): Use \n line-endings even
5676 on Windows, so that the frozen file reader will work.
5677 Reported by Josef T. Burger <bolo@bolo.com>
5679 2005-05-04 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
5681 Forward port of a patch that allowed m4-1.4.2 to compile on
5682 QNX 6.3:
5684 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
5685 sys/signal.h.
5686 * src/m4.h: And include them as appropriate.
5687 * src/main.c, src/stackovf.h: Don't include signal.h literally;
5688 m4.h will include the correct file.
5690 2005-05-04 Gary V. Vaughan <gary@gnu.org>
5692 * m4/m4private.h: Make errno visible for the sources patched
5693 below.
5695 2005-05-04 Paul Eggert <eggert@twinsun.com>
5697 * src/main.c (print_program_name_CB): Preserve errno, since
5698 M4ERROR relies on this.
5699 * modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
5700 * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
5701 * m4/path.c (m4_path_search): Don't let "free" trash errno when
5702 returning NULL.
5704 * m4/output.c (m4_insert_file): Don't assume errno has a valid
5705 value simply because fread returns zero. This fixes a
5706 portability bug reported by Marion Hakanson in
5707 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
5709 2005-05-04 Santiago Vila <sanvila@debian.org>
5711 * tests/stackovf.test: Use tempfile if available.
5713 2005-05-04 Robert Bihlmeyer <robbe@orcus.priv.at> (tiny change)
5715 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=92629
5716 * m4/output.c (m4_insert_file): Do not mix buffered and
5717 unbuffered I/O, as this breaks on the Hurd.
5719 2005-05-04 Gary V. Vaughan <gary@gnu.org>
5721 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
5722 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
5723 and libtoolize does a better job of ltdl importing now too, so
5724 take advantage of that while updating the tree:
5726 * acm4, config: Moved from here...
5727 * ltdl/m4, ltdl/config: ...to here.
5728 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
5729 src/Makefile.am, tests/Makefile.am: Removed...
5730 * Makefile.am: ...and migrated to here, with adjustments to
5731 compensate for relative path differences.
5732 * commit: Adjust relative paths.
5733 * configure.ac: Adjust relative paths.
5734 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
5735 patch.
5736 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
5737 the meanwhile, CVS HEAD libtool is needed.
5738 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
5739 stricly new enough, we also need a patch.
5740 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
5741 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
5742 (gl_MODULES): Don't list getopt and version-etc, as they don't
5743 belong in libm4.
5744 * bootstrap: After running gnulib-tool to import the listed
5745 modules, fetch getopt and version-etc into src manually.
5746 (ltdldir): Change to ltdl.
5747 * src/main.c: Adjust for changes in version-etc API.
5748 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
5749 but works when the getopt module isn't to be included in the lib.
5750 * README: Add note about patching autoconf and automake to
5751 bootstrap CVS m4.

5755 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=84416
5756 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
5757 empty file rather than to a nonexistent file. This closes a
5758 common security hole.
5759 * modules/m4.c (m4_maketemp): Implement the above, by using
5760 mkstemp rather than mktemp.
5762 2005-05-01 Gary V. Vaughan <gary@gnu.org>
5764 The FSF are moving offices today. Changed their contact address

5797 * acm4/m4-obstack.m4 (INCLUDE_OBSTACK_H): Likewise.
5798 * acm4/m4-regex.m4 (INCLUDE_REGEX_H): Likewise.

5801 2004-10-14 Noah Misch <noah@cs.caltech.edu>,
5802 Gary V. Vaughan <gary@gnu.org>
5804 * m4/m4.c (m4_context_field_table, m4_context_opt_bit_table):
5805 Protect definitions from macro expansion under -DNDEBUG by
5806 parenthesising the expanded function names.
5807 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
5808 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
5809 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
5810 (m4_is_syntax_macro_escaped): Similarly protect function
5811 definitions from macro expansion under -DNDEBUG by #undefing the
5812 matching macro names before each definition. Also, move all the
5813 function definitions to the end of the file so that any
5814 invocations in the rest of the file pick up the fast macro
5815 versions.
5816 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)
5817 (m4_set_debug_file, m4_set_trace_messages)
5818 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
5819 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
5820 (m4_set_max_debug_arg_length_opt): New fast macro versions of the
5821 option setter functions.
5823 2004-09-23 Gary V. Vaughan <gary@gnu.org>
5825 * po/POTFILES.in: Reflect move of gnulib files from gnulib/m4
5826 to gnu.
5828 2004-09-23 Gary V. Vaughan <gary@gnu.org>
5830 * src/main.c: Include gnulib files from the correct directory.
5832 * gnulib/*: Don't store any of the gnulib files in arch, as they
5833 generate spurious changes.
5834 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
5835 gnulib macros now share our macro directory.
5836 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
5837 * bootstrap: Call gnulib-tool to import from the gnulib tree.
5838 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
5839 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
5840 the gettext macros from autopoint that overwrite the gnulib-tool
5841 imported versions. Import sources and Makefile.am into the `gnu'
5842 directory. Changed all callers.
5843 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
5844 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
5845 for imported modules.
5846 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
5847 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
5848 hardcoding the gnulib macros they wrap.
5850 2004-07-15 Gary V. Vaughan <gary@gnu.org>
5852 Latest CVS libtool can preload modules in libraries, including
5853 its own module loaders! Tweak m4 so that it doesn't try to treat
5854 libltdl's module loaders as m4 modules when freezing and on exit:
5856 * gnulib/acm4/*.m4: Don't store these files in arch since they
5857 generate spurious changes.
5858 * bootstrap: Simplify initial libtoolize call, since CVS
5859 libtoolize is smarter these days.
5860 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
5861 build.
5862 * m4/module.h (m4__module_exit): Missing declaration.
5863 * m4/m4private.h (m4__module_next): New function declaration.
5864 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
5865 encapsulation. Changed all callers.
5866 (m4__module_interface): New function to verify m4 loadable module
5867 interfaces.
5868 (m4__module_init): Register the interface validator.
5869 (m4__module_exit): Only close my own modules.
5870 * modules/m4.c (unistd.h): Provide missing declaration.
5871 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
5872 (m4_expand_ranges): More missing declarations.
5873 * modules/modtest.c (export_test): Ditto.
5874 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
5875 * src/main.c (main): Bump copyright year.
5876 * tests/modules.at: Fix sed syntax error.
5879 2004-06-17 Gary V. Vaughan <gary@gnu.org>
5881 Tweaking to enable compilation with latest CVS libtool and
5882 libltdl. We can't just dump the library files directly into the
5883 m4 directory anymore now that libltdl is built from pieces itself:
5885 * bootstrap: Rewritten to use latest libtoolize sanely, and to
5886 set up libltdl subdirectory.
5887 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
5888 gnulib subdirectory's config.
5889 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
5890 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
5891 macros from gnulib.
5892 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
5893 configure.ac, so use AC_WITH_LTDL instead.
5894 * Makefile.am (SUBDIRS): Add libltdl.
5895 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
5896 gl_INCLUDED_REGEX.
5897 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
5898 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
5899 (libm4_la_LIBADD): Add LIBLTDL.
5900 * m4/ltdl.c, m4/ltdl.h: Removed.
5901 * m4/m4module.h: Include canonical ltdl.h.
5902 * po/*.po: Updated.
5904 2004-06-14 Gary V. Vaughan <gary@gnu.org>
5906 * gnulib/import: Now updates makefile fragments, and configure.ac.
5907 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
5908 * gnulib/m4/Makefile.am: include it.
5909 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
5910 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
5911 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
5912 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
5913 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
5914 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,
5915 gnulib/acm4/lib-ld.m4, gnulib/acm4/lib-prefix.m4,
5916 gnulib/acm4/error.m4, gnulib/acm4/po.m4, gnulib/acm4/regex.m4,
5917 gnulib/acm4/stdbool.m4, gnulib/acm4/stdint_h.m4,
5918 gnulib/acm4/uintmax_t.m4, gnulib/acm4/ulonglong.m4,
5919 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
5920 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
5921 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
5922 import.
5923 * gnulib/m4/getopt_int.h: New source file from latest gnulib
5924 import.
5925 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
5926 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,
5927 gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
5928 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
5929 Updated source files from latest gnulib.
5931 2004-02-29 Gary V. Vaughan <gary@gnu.org>
5933 * config/mailnotify: New file for mailing commit notifications,
5934 imported from cvs-utils.
5935 * commit: Updated from cvs-utils and tweaked for m4.
5937 2003-12-01 Gary V. Vaughan <gary@gnu.org>
5939 * config/mkstamp: Updated from CVS libtool.
5940 * configure.ac: Generate a gnu coding standards compliant version
5941 number, and use it for the banner.
5942 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
5943 mhen the TIMESTAMP changes in ChangeLog, but the file modification
5944 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
5945 contain the previous version number.
5946 * src/main.c: Make --version output conform to the GNU standard.
5948 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
5949 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
5950 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
5951 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
5952 time_la_SOURCES): ...so that these are defaulted correctly, and
5953 can be removed from this file.
5954 (AM_LDFLAGS): Add -module...
5955 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
5956 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
5957 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
5958 the individual settings can be removed.
5959 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
5960 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
5961 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
5962 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
5963 time_la_LIBADD): ...so that these are picked up as a deplib of
5964 libm4 and don't need to be set explicitly.
5966 2003-11-18 Gary V. Vaughan <gary@gnu.org>
5968 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
5969 from the standard build. It is too fragile.
5971 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
5972 CVS libtool after merging m4 changes across to libtool.
5974 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
5975 * m4/path.c (search_path_add): Ditto.
5977 2003-11-13 Gary V. Vaughan <gary@gnu.org>
5979 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
5980 libtool tags we don't use in configure. This reduces the size
5981 of the script from over 1Mb to under 700Kb.
5983 2003-11-13 Gary V. Vaughan <gary@gnu.org>
5985 The import script was not written properly, and the last gnulib
5986 import was incomplete. Fixed that problem, and reimport our
5987 gnulib dependencies, which picks up the address calculation
5988 overflow checks described by Paul below. Also tweak the clients
5989 of the gnulib xalloc module not to use deprecated macros:
5991 * gnulib/import: Recurse through module dependencies rather than
5992 naively descending only one level.
5993 * configure.ac: Add calls to gnulib's strnlen and extension module
5994 macros.
5995 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
5996 extension modules.
5997 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
5998 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
5999 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
6000 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
6001 gnulib.
6002 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
6003 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
6004 place of `xcalloc (1, S)'.
6005 * m4/m4.c (m4_create): Likewise.
6006 * m4/m4private.h (m4_symbol_value_create): Likewise.
6007 * m4/symtab.c (symtab_fetch): Likewise.
6008 * m4/syntax.c (m4_syntax_create): Likewise.
6009 * src/freeze.c (reload_frozen_state): Likewise.
6010 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
6011 macro.
6012 * m4/symtab.c (m4_symtab_create): Likewise.
6014 2003-11-13 Gary V. Vaughan <gary@gnu.org>
6016 * tests/module.at: Comment typo.
6018 2003-10-10 Gary V. Vaughan <gary@gnu.org>
6020 * tests/modules.at (modules: importing): Apply some lateral
6021 thinking, and use AT_CHECK to compare the output of a sed pass
6022 over stderr against the canonical strerror string.
6024 * tests/modules.at (modules: importing): Edit the generated stderr
6025 output to canonicalize strerror output, before a comparison.
6027 2003-10-10 Gary V. Vaughan <gary@gnu.org>
6029 Tru64UNIX perl is sloppy with namespace pollution. This patch is
6030 careful not to trip over the mess:
6032 * modules/perl.c: Some builds of perl install headers that contain
6033 `#define try __builtin_try'. Be sure to undefine that macro
6034 before `m4/hash.h' gets included, which uses the `try' symbol.
6035 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
6036 `false' before including `stdbool.h'.
6037 (DELETE): This symbol is not in m4's namespace, and is in any
6038 case only used internally...
6039 * m4/m4private.h (DELETE): ...so move it to here.
6040 Reported by Martin MOKREJS <mmokrejs@natur.cuni.cz>
6042 2003-10-08 Paul Eggert <eggert@twinsun.com>
6044 Don't use XMALLOC and XCALLOC. Once we install the
6045 corresponding patch into gnulib, this will fix some
6046 address-calculation overflow bugs on hosts where calloc (A, B)
6047 returns garbage when A*B overflows.
6049 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
6050 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
6051 xmalloc, XCALLOC with xcalloc.
6052 * m4/m4.c (m4_create): Likewise.
6053 * m4/m4private.h (m4_symbol_value_create): Likewise.
6054 * m4/output.c (m4_output_init): Likewise.
6055 * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise.
6056 * m4/syntax.c (remove_syntax_attribute): Likewise.
6057 * src/freeze.c (reload_frozen_state): Likewise.
6058 * src/main.c (main): Likewise.
6060 2003-10-07 Gary V. Vaughan <gary@gnu.org>
6062 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
6063 gnulib/acm4 directories for aclocal m4 macros.
6064 * gnulib/Makefile.am (EXTRA_DIST): Removed.
6065 (MAINTAINERCLEANFILES): Add Makefile.in.
6066 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
6067 modules we use.
6068 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
6069 * gnulib/import: New file. Temporary script for updating gnulib
6070 imported files, until gnulib-tool is working.
6071 * gnulib/config/codeset.m4, gnulib/config/error.m4,
6072 gnulib/config/exitfail.m4, gnulib/config/extensions.m4,

6108 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
6109 gnulib/acm4/xstrndup.m4: Reimported from CVS gnulib with
6110 gnulib/import script.
6111 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/error.c,
6112 gnulib/m4/error.h, gnulib/m4/exitfail.c, gnulib/m4/free.c,

6115 gnulib/m4/version-etc.c, gnulib/m4/version-etc.h,
6116 gnulib/m4/xalloc.h, gnulib/m4/xmalloc.c: Updated from CVS
6117 gnulib with gnulib/import script.
6118 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
6119 guards ready for gnulib-tool to autoupdate on import.
6120 * config/debug.m4, config/gmp.m4, config/m4-error.m4,
6121 config/m4-gettext.m4, config/m4-obstack.m4, config/m4-regex.m4,

6123 * acm4/debug.m4, acm4/gmp.m4, acm4/m4-error.m4,
6124 acm4/m4-gettext.m4, acm4/m4-obstack.m4, acm4/m4-regex.m4,
6125 acm4/stackovf.m4: ...to here, to separate aclocal macros from
6126 configure time helper scripts.
6127 * config/error.m4: Removed; superceded by gnulib/acm4/error.m4.
6128 * m4/hash.c, m4/m4.c, m4/macro.c, m4/module.c, m4/output.c,
6129 m4/path.c, m4/symtab.c, m4/syntax, m4/system_.h, modules/m4.c,

6131 gnulib xalloc.h.
6132 * src/main.c (version_etc_copyright): Only output the current
6133 year.
6134 (version_etc): Call with new variadic API.
6136 2003-09-16 Gary V. Vaughan <gary@gnu.org>
6138 * gnulib/m4/version-etc.c, gnulib/m4/version-etc.h: Import
6139 version-etc module from CVS gnulib.
6140 * po/POTFILES.in: Add gnulib/m4/version-etc.c.
6141 * src/Makefile.am: Build it.
6142 * src/main.c: Use it.
6144 * gnulib/m4/exit.h: Import exit module from CVS gnulib.
6145 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
6146 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
6147 exit.h instead.
6149 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
6150 Gary V. Vaughan <gary@gnu.org>
6152 * bootstrap: Separate options.
6153 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
6154 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
6155 not set.
6156 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
6157 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
6158 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
6159 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
6160 $(LTLIBINTL) for gettext support on cygwin.
6161 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
6162 have $(LTLIBINTL) from the preloaded module la files.
6163 * README: Remove the warning about using --disable-nls on Windows
6164 machines.
6166 2003-09-15 Gary V. Vaughan <gary@gnu.org>
6168 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
6169 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
6170 is required.
6172 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6174 * doc/STYLE: Document the gnulib header naming conventions, and
6175 #include policy.
6176 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
6177 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,
6178 gnulib/m4/gettext.h, gnulib/m4/obstack.h, gnulib/m4/regex.h
6179 respectively.
6180 * gnulib/m4/Makefile.am: Remove the rules to build these headers.
6182 * gnulib/m4/strtol.c, gnulib/config/strtol.m4: Import strtol
6183 module from CVS gnulib.
6184 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
6185 (gl_FUNC_STRTOL): In favour of the module macro.
6187 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6189 Replace the getopt code with CVS gnulib getopt. The source files
6190 detect whether they are in a glibc environment and preprocess away
6191 all of the code if there is a system getopt, so we can compile
6192 them into the m4 executable unconditionally:
6194 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
6195 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
6196 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
6197 macros.
6198 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
6199 version.
6200 * src/Makefile.am: Adjust.
6201 * src/main.c: Always include our shipped getopt.h.
6202 * po/POTFILES.in: Use new location of getopt.c.
6204 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6206 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
6207 * config/Makefile.am: Removed. Automake 1.8 distributes the files
6208 in this directory automatically.
6209 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
6211 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
6212 isn't set yet.
6213 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
6214 inline.
6215 * modules/Makefile.am (pkglibexecdir): Set it here.
6216 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
6218 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
6219 Import regex module from CVS gnulib.
6220 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
6221 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
6222 do extra substitutions for Makefile.
6223 * configure.ac: Use it.
6224 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
6225 from regex_.h if necessary.
6226 * m4/system_.h: Include the correct version of regex.h.
6227 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
6228 version.
6229 * po/POTFILES.in: Use new location of regex.c.
6231 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
6232 realloc.c: automake distributes these files already.
6234 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6236 Replace the xstrzdup code by importing the xstrndup module from
6237 CVS gnulib, along with its dependencies: strndup and strnlen:
6239 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
6240 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
6241 gnulib.
6242 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
6243 gnulib/config/strndup.m4: Ditto wrt strndup.
6244 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
6245 strnlen.
6246 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
6247 However, contrary to gnulib, we install xstrndup.h.
6248 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
6249 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
6250 is an artifact of the old m4 portability layer.
6251 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
6252 * m4/system_.h: Include xstrndup.h.
6253 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
6255 2003-09-11 Gary V. Vaughan <gary@gnu.org>
6257 Reimport the latest xalloc module from CVS gnulib, and adjust the
6258 m4 sources to take advantage of xalloc xfree. Also create a new
6259 macro DELETE with the same semantics as the old m4 XFREE macro,
6260 and carefully tweak callers:
6262 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
6263 gnulib.
6264 * m4/utility.c (xfree): Removed. This function is now supplied by
6265 gnulib xalloc.
6266 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
6267 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
6268 * m4/symtab.c (m4_symtab_create): Ditto.
6269 * m4/system_.h: Removed XFREE redefine.
6270 (DELETE): New macro with same functionality as the original m4
6271 XFREE macro, but based on xalloc.h now. Changed all callers.
6272 * src/main.c (main): Use XMALLOC macro.
6273 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
6274 instead of XFREE.
6275 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
6277 2003-09-10 Gary V. Vaughan <gary@gnu.org>
6279 Import the xalloc module from CVS gnulib, along with its
6280 dependencies: exitfail, malloc and realloc. We had different
6281 semantics for our XFREE and a function xfree() not supplied by
6282 gnulib, so also a bit of work to keep everything running
6283 smoothly:
6285 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
6286 (gl_XALLOC): Use gnulib equivalents.
6287 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
6288 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
6289 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
6290 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
6291 realloc.
6292 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
6293 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
6294 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
6295 imported modules.
6296 (pkgincdir): Removed. Use pkgincludedir instead.
6297 * m4/m4private.h (XFREE): xfree already checks for NULL.
6298 * m4/system_.h: Use xalloc module, and remove macros already
6299 supplied by xalloc.h.
6300 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
6301 moved the old definition from m4/xmalloc.c to here for now.
6303 2003-09-09 Gary V. Vaughan <gary@gnu.org>
6305 Import the error and progname modules from CVS gnulib. Our old
6306 error.c subsumed the functionality of both, so a little adjustment
6307 was required to accomodate the split in sources. Also added more
6308 wrapper macros to choose between a system installed error.h or our
6309 shipped gnulib error module:
6311 * m4/error.c, m4/error.h: Removed.
6312 * m4/Makefile.am: Adjust.
6313 (pkgincdir): Removed. Use pkgincludedir instead.
6314 * m4/module.h, src/main.c: Don't include `m4/error.h'.
6315 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
6316 error.h.
6317 * gnulib/m4/progname.c: Imported from CVS gnulib.
6318 * gnulib/m4/progname.h: Ditto.
6319 * src/main.c: Adjust to use progname module.
6320 * gnulib/m4/error.c: Imported from CVS gnulib.
6321 * gnulib/m4/error_.h: Ditto.
6322 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
6323 if appropriate, and link a local error.h if the system version is
6324 missing.
6325 (libgnu_la_SOURCES) Add progname module sources.
6326 * gnulib/config/error.m4: Imported from CVS gnulib.
6327 * gnulib/config/strerror_r.m4: Ditto.
6328 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
6329 to have ERROR_H for Makefile substitutions and tell system.h
6330 whether the system error.h should be used, or a locally installed
6331 version.
6332 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
6334 2003-09-09 Gary V. Vaughan <gary@gnu.org>
6336 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
6337 s/gettext_.h/gettext.h/.
6339 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
6340 automake have been fixed.
6342 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
6343 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
6344 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
6345 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
6347 2003-09-09 Gary V. Vaughan <gary@gnu.org>
6349 The gnulib obstack module requires the gnulib gettext module for
6350 systems that do not have GNU gettext installed. Because we use
6351 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
6352 that directory incase it clashes with the system gettext.h. This
6353 delta uses gettext_.h and extra rules in the Makefile to make a
6354 link to gettext.h when needed:
6356 * Makefile.am (auxdir): Removed. No longer used.
6357 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
6358 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
6359 moved.
6360 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
6361 Makefile based build.
6362 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
6363 of the macros are kept.
6364 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
6365 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
6366 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
6367 distributes these automatically.
6368 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
6369 warning from automake-1.7a.
6370 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
6371 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
6372 all callers.
6373 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
6374 wrt. m4_FUNC_OBSTACK.
6375 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
6376 wrt. m4_sys_STACKOVF.
6377 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
6378 wrt. _m4_LIB_GMP, m4_LIB_GMP.
6379 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
6380 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
6381 respectively.
6382 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
6383 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
6384 gettext.h link on deficient systems.
6385 (pkginc_HEADERS): Mention $(GETTEXT_H).
6386 (EXTRA_HEADERS): Mention gettext.h.
6387 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
6388 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
6389 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
6390 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
6391 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
6392 gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
6393 gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
6394 gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
6395 gnulib/config/po.m4, gnulib/config/progtest.m4,
6396 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
6397 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
6399 2003-09-05 Gary V. Vaughan <gary@gnu.org>
6401 We can't mirror the gnulib directory structure here, since we need
6402 to be able to eg. `#include <m4/obstack.h>' from our source files,
6403 which is much easier if the local obstack.h is created in a
6404 directory named m4. Rather than trying to symlink everything into
6405 the m4 directory, now we build a libtool convenience library from
6406 the sources we get from gnulib and link that with libm4.la:
6408 * gnulib/config/extensions.m4: Imported from CVS gnulib.
6409 * gnulib/config/unlocked-io.m4: Ditto.
6410 * gnulib/m4/unlocked-io.h: Ditto.
6411 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
6412 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
6413 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
6414 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
6415 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
6416 * m4/Makefile.am: Adjust.
6417 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
6418 macros we redistribute.
6419 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
6420 library among others.
6421 (GNULIB_SRCS, GNULIB_MACROS): Removed.
6422 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
6423 * config/m4-obstack.m4: Adjust.
6424 * po/POTFILES.in: Adjust.
6425 * configure.ac: Reformatting. Call newly imported gnulib macros.
6426 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
6427 bogus calls of `#include "m4.h"'.
6428 * Makefile.am: INCLUDES has been deprecated in favour of
6429 AM_CPPFLAGS.
6430 * m4/Makefile.am: Ditto.
6431 * modules/Makefile.am: Ditto.
6432 * src/Makefile.am: Ditto.
6434 2003-09-05 Gary V. Vaughan <gary@gnu.org>
6436 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
6438 2003-09-04 Gary V. Vaughan <gary@gnu.org>
6440 Migrate the obstack support into the gnulib directories for easy
6441 synchronisation with upstream files in gnulib:
6443 * config/gnu-obstack.m4: Moved from here...
6444 * config/m4-obstack.m4: ...to here.
6445 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
6446 * m4/obstack.c, m4/obstack_.h: Moved from here...
6447 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
6448 * po/POTFILES.in: Adjust.
6449 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
6450 * m4/Makefile.am: Add a whole new section to link the obstack
6451 sources from the gnulib tree if necessary.
6452 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
6453 from gnulib.
6454 * config/m4-obstack.m4: Rewrite as a wrapper for
6455 gnulib/m4/obstack.m4.
6457 2003-09-04 Gary V. Vaughan <gary@gnu.org>
6459 GNU M4 currently builds with a number of files adapted from
6460 upstream sources. Recently the gnulib project on savannah.gnu.org
6461 has pulled together a great many of these externally maintained
6462 files. This delta is the beginnings of isolating those files
6463 maintained in gnulib to make it easy to synchronise M4 with the
6464 upstream files prior to releases.
6466 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
6467 directory.
6468 (SUBDIRS): Added new gnulib subdirectory.
6469 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
6470 * config/stdbool.m4: Moved from here...
6471 * gnulib/m4/stdbool.m4: ...to here.
6472 * m4/stdbool_.h: Moved from here...
6473 * gnulib/lib/stdbool_.h: ...to here.
6474 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
6475 distributed.
6476 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
6477 code to work with new stdbool_.h location.
6478 (gnulib_srcdir): New.
6480 2003-09-04 Gary V. Vaughan <gary@gnu.org>
6482 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
6483 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
6484 builds to work.
6485 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
6486 (EXTRA_DIST): Use it.
6488 * bootstrap: CVS autoreconf leaves file droppings. Remove
6489 aclocal.m4t incase autoreconf doesn't.
6491 2003-08-29 Gary V. Vaughan <gary@gnu.org>
6493 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
6494 the other gnulib imports, renamed to m4/obstack_.h.
6495 * m4/obstack.c: Updated from CVS gnulib.
6496 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
6497 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
6498 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
6499 about vpath already, and $top_srcdir upsets CVS Automake, so the
6500 $top_srcdir reference was removed.
6502 * m4/system-h.in: For consistency with the gnulib imports, renamed
6503 to m4/system_.h.
6504 * m4/Makefile (EXTRA_HEADERS): Adjust.
6505 * configure.ac (AC_CONFIG_FILES): Adjust.
6507 * m4/stdbool_.h: New file from gnulib for systems without their
6508 own.
6509 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
6510 * config/stdbool.m4: New file. Macros from gnulib for same.
6511 * configure.ac: Use it.
6513 2003-08-27 Gary V. Vaughan <gary@gnu.org>
6515 * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'`

6562 * src/main.c: Ditto.
6563 * src/stackovf.c: Ditto.
6565 * config/gmp.m4 (M4_AC_LIB_GMP): Use AC_INCLUDES_DEFAULT:
6566 ac_default_headers is an autoconf internal variable.
6567 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
6568 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
6570 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
6571 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
6572 delta.
6574 2003-08-15 Gary V. Vaughan <gary@gnu.org>
6576 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
6577 C99 bool.
6578 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
6579 possible or faking one with a typedef. Changed all callers.
6581 2003-08-15 Gary V. Vaughan <gary@gnu.org>
6583 Still cleaning up the users' module API, by taking out the stuff
6584 that isn't used by any existing modules, and moving specialised
6585 functions out of libm4 and into the module they are used by.
6587 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
6588 * m4/utility.c (m4_skip_space): ...to here the home of its only
6589 use, made static and renamed to `skip_space'. Changed all
6590 callers.
6591 * m4/m4module.h (m4_expand_ranges): Removed prototype.
6592 * m4/utility.c (m4_expand_ranges): Moved definition from here...
6593 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
6594 ltdl.
6595 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
6596 casting .
6597 * modules/gnu.c (builtin_syntax): Import and use in this
6598 builtin implementation.
6599 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
6600 Not used. Deleted.
6601 * m4/macro.c (trace_flush): Except here where the macro is now
6602 manually inlined.
6603 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
6604 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
6605 moved...
6606 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
6607 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
6609 2003-08-14 Gary V. Vaughan <gary@gnu.org>
6611 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
6612 compiler based AC_CHECK_HEADER that was introduced in
6613 autoconf-2.56.
6614 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
6615 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
6616 * configure.ac: Use renamed M4_AC_LIB_GMP.
6618 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
6619 macro that requires arguments! This stops the shell's bad
6620 substitution error at configure time.
6622 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
6623 variables to the testsuite shell. Set the value of USE_GMP so
6624 that the gmp test will run!
6625 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
6627 2003-08-11 Gary V. Vaughan <gary@gnu.org>
6629 Libltdl already has an excellent mechanism for accessing C symbols
6630 in modules. Lets use that! Remove all the exporting cruft and
6631 just use lt_dlsym in conjunction with a few conventions to
6632 simplify module writers' jobs. Also removed the table address
6633 caching code and otherwise simplified the module loader quite a
6634 bit. To access exported symbols in other modules, first the
6635 exporting module must name the symbols <modname>_LTX_<symname>,
6636 and the importing module must define a function type called
6637 <symname>_func. The importer then adds
6638 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
6639 that wishes to call out to the exported functions. Care must be
6640 taken that <symname> is non-NULL in the importing module incase
6641 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
6642 definition was in the importers source. Study
6643 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
6644 m4_module_import will attempt to automatically load a module
6645 required for symbol access if it is not loaded already.
6647 * TODO: Removed the items fixed in this delta.
6648 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
6649 module name.
6650 * m4/ltdl.h (lt_dlhandle_find): Declare it.
6651 * m4/module.c (m4_module_unload): Use it.
6652 * src/freeze.c (reload_frozen_state): Ditto.
6653 * m4/m4module.h (m4_export): Deleted. Removed all references.
6654 (M4_MODULE_IMPORT): New user convenience macro for importing
6655 arbitrary symbols from other modules.
6656 * m4/module.c (m4_module_import): New function to service
6657 M4_MODULE_IMPORT macro.
6658 (module_data): Removed. Looking up the tables on demand with
6659 lt_dlsym, rather than caching their addresses here simplifies the
6660 code substantially.
6661 (m4_get_module_builtin_table, m4_get_module_macro_table):
6662 Removed. Changed all callers.
6663 (set_module_macro_table, set_module_builtin_table): Renamed to
6664 install_macro_table and install_builtin_table respectively, and
6665 simplified now that the cache is no more.
6666 * modules/gnu.c (builtin_symbols): Use this new mechanism to
6667 import m4_dump_symbols from the m4 module.
6668 (builtin_esyscmd): Likewise for m4_set_sysval and
6669 m4_sysval_flush.
6670 * modules/m4.c (m4_export_table): Removed. Functions are
6671 addressed with the new mechanism which doesn't need this.
6672 (m4_set_sysval): New exported accessor function to prevent
6673 problems with variable access on inferior architectures.
6674 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
6675 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
6676 that we can have some type safety.
6677 * modules/modtest.c (export_test): C level exported function for
6678 testing the new import mechanism.
6679 * modules/import.c: New file for the import end of the test.
6680 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
6681 * tests/modules.at: New test cases for intermodule symbol
6682 importing.
6684 2003-08-07 Gary V. Vaughan <gary@gnu.org>
6686 * m4/m4module.c (m4_string): Moved from here...
6687 * m4/m4private.c (m4_string): ...to here.
6689 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
6691 2003-07-29 Gary V. Vaughan <gary@gnu.org>
6693 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
6694 already available to module writers through
6695 m4_{get,set}_nesting_limit_opt(), so moved from here...
6696 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
6697 (m4_create): Use it.
6699 2003-07-28 Gary V. Vaughan <gary@gnu.org>
6701 Aside from auditing path.c for m4module.h api obfuscation, this
6702 delta introduces the concept of private struct members in opaque
6703 data types to GNU m4: See the STYLE file for details.
6705 * TODO: Remind ourselves that a rewrite of path.c is needed.
6706 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
6707 Moved from here...
6708 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
6709 here and renamed. These type definitions are for internal api use
6710 only. Changed all callers.
6711 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
6712 Moved from here...
6713 * m4/path.c (search_path_env_init, search_path_add): ...to here
6714 and renamed. These calls were never used outside this file.
6715 Changed all callers.
6716 (dirpath): Moved functionality of this static declaration...
6717 * m4/m4private.h (struct m4): ...to this new internal only
6718 search_path field. Changed all callers.
6719 (m4__get_search_path): Added new internal api accessor.
6720 * m4/path.c (m4_search_path_info_new): Removed. Not used.
6721 (m4_include_init): Removed...
6722 * m4/m4.c (m4_create): ...because the new m4 field is now
6723 initialised here.
6724 (m4_delete): Recycle search_path memory.
6725 * src/main.c (main): Don't call m4_include_init now that it's
6726 gone!
6727 * doc/STYLE: Document convention for private fields in opaque
6728 ADTs.
6730 2003-07-24 Gary V. Vaughan <gary@gnu.org>
6732 Sometimes exporting the address of a symbol from a module isn't
6733 enough for other modules to call that symbol correctly. If
6734 custom data types are used for function parameters, they need to
6735 be known to the caller. This change introduces the concept of
6736 $(prefix)/include/modules/$(modulename).h to declare those
6737 structures. Also we move m4_dump_symbols from libm4 to the m4
6738 module to show this concept in action.
6740 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
6741 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
6742 exporting data structures from modules/m4.c.
6743 * modules/m4.c, modules/gnu.c: Include it.
6744 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
6745 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
6746 prototypes.
6747 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
6748 Moved from here...
6749 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
6750 ...to here, with slight renaming.
6751 (m4_export_table): Prototype and add m4_dump_symbols.
6752 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
6753 definition of m4_dump_symbols.
6754 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
6755 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
6757 2003-07-24 Gary V. Vaughan <gary@gnu.org>
6759 Create an export table in modules/m4.c in readiness for beefing up
6760 the module loader to track module exports and imports.
6762 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
6763 * m4/debug.c (m4_debug_flush_files): Moved...
6764 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
6765 * modules/gnu.c (builtin_esysval): Use it.
6766 * m4/m4module.h (m4_export): New type for declaring module symbols
6767 for export.
6768 * modules/m4.c (m4_export_table): List symbols exported from this
6769 module for use by other modules.
6771 2003-07-24 Gary V. Vaughan <gary@gnu.org>
6773 An experiment: There is loads of code in libm4 which should be in
6774 the m4 module, but is also used by another module. Just because
6775 some linkers won't cope with calls across dynamic runtime loaded
6776 objects I initially left the code in libm4. It will tidy the
6777 module api immensely if this code moves to the right place, I just
6778 need to remember to invent a suitable calling mechanism at some
6779 point. For now, only modules that are statically linked and
6780 preloaded will get this treatment, so the only platforms that will
6781 break are those that require all symbols to be resolved at link
6782 time.
6784 * TODO: Reminder that what I am doing could reduce portability
6785 unless I do something more robust later.
6786 * m4/m4module.h (m4_sysval): No longer exported from libm4.
6787 * m4/utility.c (m4_sysval): No longer declared in libm4.
6788 * modules/Makefile.am: Reformatting.
6789 * modules/m4.c (m4_sysval): Declare it at place of use.
6790 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
6792 2003-07-23 Gary V. Vaughan <gary@gnu.org>
6794 * m4/m4module.h: Reformatting and rearranging lines a bit.
6795 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
6796 all users.
6797 (m4_call_macro, m4_expand_input): Renamed...
6798 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
6799 callers.
6800 (m4_expansion_level, m4_process_macro): Moved...
6801 * m4/macro.c (expansion_level, process_macro): ...to here, and
6802 made static.
6804 * m4/m4module.h (program_name): Not used by modules at all, so
6805 moved...
6806 * src/main.c (program_name): ...to here.
6807 (print_program_name): Renamed...
6808 (print_program_name_CB): ...to conform to the STYLE guide.
6810 2003-07-23 Gary V. Vaughan <gary@gnu.org>
6812 More refactoring of the m4module.h API. Replace #defines with an
6813 enum, and move non-public functions out of the public API.
6815 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
6816 inclusion.
6817 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
6818 * m4/debug.c (m4_debug, trace): Moved...
6819 * m4/m4private.h (struct m4): ...to fields of this struct.
6820 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
6821 for the new fields.
6822 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
6823 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
6824 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
6825 * m4/m4module.h (m4_context_field_table): Add entries for new
6826 debug_file and trace_messages fields.
6827 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
6828 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
6829 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
6830 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
6831 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
6832 (m4_is_debug_bit): New macro to simplfy checks against the debug
6833 bits above.
6834 (m4_trace_format, m4_trace_header, m4_trace_flush)
6835 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
6836 prototypes.
6837 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
6838 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
6839 * m4/macro.c (trace_format, trace_header, trace_flush)
6840 (trace_prepre, trace_pre, trace_post): ...to these newly static
6841 functions, since they are only ever used from this file. Changed
6842 all callers.
6844 2003-07-17 Gary V. Vaughan <gary@gnu.org>
6846 Change the macros for checking syntax so that matching against
6847 multiple possible syntax classes can be done with a single
6848 comparison some of the time. The various classes are now bits of
6849 an int that can be checked with bitwise logic operators.
6851 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
6852 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
6853 (M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)
6854 (M4_SYNTAX_ASSIGN, M4_SYNTAX_ALPHA, M4_SYNTAX_NUM)
6855 (M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)
6856 (M4_SYNTAX_ECOMM): Replaced #defines with an enum.
6857 (M4_SYNTAX_ALNUM): Removed. Changed all callers.
6858 (M4_IS_IGNORE, M4_IS_OTHER, M4_IS_SPACE, M4_IS_OPEN, M4_IS_CLOSE)
6859 (M4_IS_COMMA, M4_IS_DOLLAR, M4_IS_ACTIVE, M4_IS_ESCAPE)
6860 (M4_IS_ASSIGN, M4_IS_ALPHA, M4_IS_NUM, M4_IS_LQUOTE, M4_IS_RQUOTE)
6861 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
6862 Replace all calls with invocations of these...
6863 (m4_is_syntax, m4_has_syntax): ...New macros.
6864 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
6865 is no longer required with new macros. Changed all callers.
6867 2003-07-15 Gary V. Vaughan <gary@gnu.org>
6869 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
6870 values are returned as part of the internal interface, so they
6871 need to be moved...
6872 * m4/private.h: ...to here.
6873 * m4/macro.c (expand_token): Check for out of range
6874 m4_peek_input() results before looking up in the syntax table.
6875 (collect_arguments): Ditto.
6877 * NEWS: Note `$' syntax class.
6879 2003-07-08 Paul Eggert <eggert@twinsun.com> and
6880 Gary V. Vaughan <gary@gnu.org>
6882 Conform to POSIX if the POSIXLY_CORRECT environment is set.
6883 --traditional `define' now smashes all the definitions.
6885 * NEWS: Explain this.
6886 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
6887 (Extensions): Explain that extensions that are incompatible with
6888 POSIX are disabled if POSIXLY_CORRECT is set.
6889 (Incompatibilities): Remove.
6890 (Define, Other Incompat): Explain difference
6891 between GNU and POSIX behavior of define, pushdef, popdef.
6892 * m4/m4.c (m4_get_posixly_correct_opt): New undef.
6893 * m4/m4module.h (m4_context_opt_bit_table): Add POSIXLY_CORRECT entry.
6894 * m4/m4private.h (M4_OPT_POSIXLY_CORRECT_BIT): New macro.
6895 (m4_get_posixly_correct_opt): New macro.
6896 * m4/m4macro.c (m4_process_macro): Disable $10, $abc etc. if
6897 POSIXLY_CORRECT.
6898 * modules/m4.c (builtin_functions): defn now takes any number of args.
6899 (builtin_define): Smash all the definitions if
6900 POSIXLY_CORRECT.
6901 (builtin_defn)): Allow any number of arguments.
6902 (builtin_undivert): Do not allow nonnumeric arguments
6903 if POSIXLY_CORRECT.
6904 * src/main.c (main): Set posixly-correct behavior if either
6905 POSIXLY_CORRECT is set, or if -G is given.
6906 * tests/builtins.at: New test for smashed definitions.
6908 2003-06-27 Gary V. Vaughan <gary@gnu.org>
6910 * doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
6911 * m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
6912 not to slow the parser down.
6913 (M4__IS_STRING): New macro to test string syntax class membership.
6914 * m4/syntax.c: Adjust docucomment.
6915 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
6916 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
6917 * m4/input.c (init_builtin_token): Comment typo.
6918 (m4__next_token): Comment typo.
6919 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
6920 by using the new M4__IS_STRING macro.
6921 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
6922 variable references in macro expansions.
6924 * doc/m4.texinfo (Eregexp and Regexp): Typo.
6925 (Epatsubst and Patsubst): Typo.
6926 (Eval): Typo.
6928 2003-06-26 Gary V. Vaughan <gary@gnu.org>
6930 Move the global variables that pertain to syntax to a new `struct
6931 m4_syntax_table', and then add one of these to `struct m4'. The
6932 ripple effect through the code to both change formerly global
6933 references, and make sure a suitable context is available in
6934 lexical scope is disproportionately large compared to the size of
6935 the change proper. This change is a large part of decoupling
6936 syntax.c from the rest of the code that uses it.
6938 * m4/m4private.h (struct m4): Add a syntax field.
6939 * m4/m4.c (m4_create): Initialise it,
6940 (m4_delete): Recycle it.
6941 (m4_get_symtab): Remove hand coded version...
6942 (m4_get_symbol_table): ...and generate this with cpp. Changed all
6943 callers.
6944 * m4/m4module.h (m4_context_field_table): Add an extra field so we
6945 can generate m4_get_symbol_table. Add a new row for
6946 m4_get_syntax_table.
6947 (M4SYNTAX): Syntactic sugar for module writers.
6948 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
6949 (m4_syntax_table): New home for syntax related formerly global
6950 variables.
6951 * m4/m4private.h (struct m4_syntax_table): Define it.
6952 * m4/input.c (m4_input_init): Initialisation of these formerly
6953 global variables moved...
6954 * m4/syntax.c (m4_syntax_create): ...to here.
6955 * m4/input.c (m4_input_exit): And similarly, recycling of the
6956 memory used by those values moved...
6957 * m4/syntax.c (m4_syntax_delete): ...to here.
6958 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
6959 Moved to m4/m4private.h.
6960 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
6961 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
6962 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
6963 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
6964 objects. Changed all callers that used to directly access the
6965 global equivalents.
6966 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
6967 Removed and incorporated into m4_syntax_table structure.
6968 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
6969 * m4/syntax.c (m4_set_syntax): Now returns an error status,
6970 instead of requiring a `struct m4' to generate its own errors.
6971 Changed all callers.
6972 * src/main.c (main): Now that the syntax table is initialised as
6973 part of m4_create, we have to manually wipe the syntax entries if
6974 we are about to read a frozen file.
6976 2003-06-26 Gary V. Vaughan <gary@gnu.org>
6978 * doc/STYLE: Added notes on callback naming schemes.
6980 * m4/module.c (m4_set_module_macro_table)
6981 (m4_set_module_builtin_table): Declarations weren't changed when
6982 definitions were renamed on 2003-06-19.
6984 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
6985 neither used nor particularly appropriate since it exposes the
6986 internal workings of the hash module. I haven't yet decided
6987 whether to remove it entirely.
6989 2003-06-20 Gary V. Vaughan <gary@gnu.org>
6991 Two related changes, and a huge knockon effect throughout the
6992 source: Moved the option variables out of global space and into
6993 `struct m4'; made `m4_symtab' a real datatype, so that its api
6994 is not marred passing `struct m4' around just so it can decide
6995 whether to keep traced symbol names or not. Added setters and
6996 getters for the formerly global option variables, and obviously
6997 changed a vast number of functions to take a `struct m4' and use
6998 the getter funcs to find option values.
7000 * m4/utility.c (interactive, sync_output, debug_level)
7001 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
7002 (max_debug_argument_length, warning_status, nesting_limit)
7003 (discard_comments): Removed.
7004 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
7005 (debug_level, max_debug_argument_length, prefix_all_builtins)
7006 (suppress_warnings, discard_comments, interactive, sync_output):
7007 Removed from here...
7008 * m4/m4private.h (struct m4): ...and equivalent fields added to
7009 this structure.
7010 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
7011 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
7012 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
7013 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
7014 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
7015 macros for the new fields.
7016 * m4/m4module.h (m4_context_field_table)
7017 (m4_context_opt_bit_table): Helper macros used to generate
7018 prototypes, setters and getters for new option fields
7019 consistently.
7020 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
7021 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
7022 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
7023 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
7024 (m4_get_interactive_opt, m4_get_sync_output_opt)
7025 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
7026 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
7027 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
7028 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
7029 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
7030 setter and getter functions generated by cpp from
7031 m4_context_field_table and m4_context_opt_bit_table, exported as
7032 part of the module api. Changed all callers.
7033 * m4/symtab (struct m4_symtab): Used as the concrete type for
7034 m4_symtab now.
7035 (m4_symtab_create): Allocate and initialise a new struct.
7036 (m4_symtab_apply): New function that works like m4_hash_apply, but
7037 with different callbacks specific to symbol tables. Changed all
7038 callers.
7039 (symbol_destroy, arg_destroy, arg_copy): Renamed
7040 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
7041 they have unused parameters for a reason!
7042 (dump_symbol_CB): New callback to dump the contents of a single
7043 symbol.
7044 (symtob_dump): Rewritten in terms of dump_symbol_CB.
7045 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
7046 Changed all callers.
7047 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
7048 of the contained `m4_symtab' at the `no_gnu_extensions' field.
7049 Although I'm not convinced these semantics are correct, they are
7050 at least consistent with how things were before this delta. Also
7051 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
7053 2003-06-19 Gary V. Vaughan <gary@gnu.org>
7055 Tie down the interface to libm4 some more. Make more structures
7056 opaque to modules by moving them to m4private.h, and writing
7057 setters and getters. To win back the speed penalty for doing this
7058 also wrote macroized versions that do know about structure layout
7059 in m4private.h and #include that file into modules when NDEBUG is
7060 defined at compile time. There are still some accessor macros in
7061 m4private.h that need to go, but that is not necessary to clean
7062 the module api up.
7064 * m4/m4module.h (m4_symbol_type): Moved...
7065 * m4/m4private.h (m4__symbol_type): ...to here.
7066 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
7067 (m4_set_symbol_traced, m4_set_symbol_name_traced)
7068 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
7069 (m4_get_symbol_func, m4_symbol_value_create)
7070 (m4_symbol_value_delete, m4_set_symbol_value_text)
7071 (m4_set_symbol_value_func): New exported api to symbols.
7072 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
7073 and m4_is_symbol_value_func.
7074 * m4/m4module.h: Prototype these guys.
7075 * m4/module.c (m4_set_module_macro_table)
7076 (m4_set_module_builtin_table): Make these static, there is no
7077 reason to pollute the api with them.
7078 * m4/m4private.h: Reformatting.
7079 (m4_get_symtab): Only define when NDEBUG is defined.
7080 (m4_get_symbol_value, m4_get_symbol_traced)
7081 (m4_set_symbol_traced, m4_set_symbol_name_traced)
7082 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
7083 (m4_get_symbol_func, m4_symbol_value_create)
7084 (m4_symbol_value_delete, m4_set_symbol_value_text)
7085 (m4_set_symbol_value_func): Macro implementations of the new
7086 functions when NDEBUG is defined.
7087 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
7088 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
7089 Superceded by the above. All callers changed.
7090 (M4ARG): Removed. This is no longer different to the
7091 m4/m4module.h definition.
7092 * modules/gnu.c, modules/m4.c: Only include m4private.h when
7093 NDEBUG is defined. That way we exercise the same (albeit slower)
7094 api that external modules must use.
7096 2003-06-18 Gary V. Vaughan <gary@gnu.org>
7098 Renamed some of the types and their accessors to make more sense.
7099 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
7100 has a stack of SYMBOL_VALUEs.
7102 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
7103 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
7104 m4_get_symbol_value_type, m4_get_symbol_value_text,
7105 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
7106 Changed all callers.
7107 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
7108 (m4_get_token_type): Renamed
7109 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
7110 to the internal api.
7111 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
7112 s/TOKEN_/VALUE_/
7113 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
7114 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
7115 (m4__token_type): Moved here from m4module.h.
7116 (m4__next_token): Renamed from m4_next_token.
7117 * m4/symtab.c: Removed some of the parameterised macro support
7118 functions for modularisation later.
7119 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
7120 m4_hash_dup to perform a true deep copy of the SRC.
7121 (arg_copy): Callback for m4_symbol_value_copy.
7122 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
7123 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
7124 m4_get_symbol_value_func. Changed all callers.
7126 2003-06-18 Gary V. Vaughan <gary@gnu.org>
7128 Tidy up style of hash.[ch] in accordance with doc/STYLE.
7130 * m4/hash.c: Internal symbol renaming and formatting.
7131 (m4_hash_dup): New function to facilitate deep copies of hash
7132 tables.
7133 (m4_hash_apply_func): Returns a void* now, which is a richer type
7134 for returning exceptions (NULL means keep going).
7135 (m4_hash_apply): Ditto.
7136 * m4/hash.h: Declare exported symbols with an explicit extern.
7137 Reformated.
7139 2003-06-17 Gary V. Vaughan <gary@gnu.org>
7141 Still refactoring furiously. This delta represents a change in
7142 semantics to symtab.c. Instead of building temporary m4_tokens
7143 in the caller, and copying fields in the methods, we now create
7144 the actual m4_token for hashing in the caller so the methods just
7145 slot them in directly. Also, this means that we don't lookup a
7146 symbol and get back an allocated but VOID token to copy fields
7147 into, we create the token we want to push and pass that to
7148 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
7149 a few other small changes to stop knowledge of the implementation
7150 of symtab.c leaking out into other files.
7152 * m4/macro.c (expand_argument): Comment typo corrected.
7153 * m4/symtab.c (symtab_fetch): New function to fetch the address of
7154 an interned symbol.
7155 (m4_symbol_pushdef): Take an extra value parameter and use this
7156 directly as the new top of the value stack. All callers changed
7157 to build a token and pass responsibility for memory in, rather
7158 than copying as we used to.
7159 (m4_symbol_define): Also use the new value parameter directly as a
7160 replacement for the top of the value stack. All callers changed
7161 to build a token as above.
7162 (m4_set_symbol_traced): New function to set the traced bit on the
7163 named symbol, creating it if necessary.
7164 (symbol_popval): The guts of the old m4_symbol_popdef.
7165 (m4_symbol_popdef): Use it.
7166 * m4/builtin.c (m4_symbol_set_token): Removed,
7167 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
7168 replaced...
7169 * m4/module.c (m4_set_module_builtin_table)
7170 (m4_set_module_macro_table): ...with these more orthogonal
7171 functions.
7172 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
7173 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
7174 required.
7175 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
7176 (m4_arg_signature_parse): Moved...
7177 * m4/symtab.c: ...to here.
7178 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
7179 screw something up. Moved...
7180 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
7181 actually does a proper deep copy of source to dest.
7183 2003-06-16 Gary V. Vaughan <gary@gnu.org>
7185 Further refactoring to stabilise the module API. Renaming some
7186 functions for orthogonality, and judicious definition migration to
7187 move things out of the set of exported symbols.
7189 * doc/STYLE: New file. Notes on coding style.
7190 * m4/m4module.c: Updated bitrotted docucomment at the top of the
7191 file.
7192 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
7193 m4_get_module_name, m4_get_module_builtin_table,
7194 m4_get_module_macro_table which are verb phrases. Changed all
7195 callers.
7196 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
7197 Moved to...
7198 * m4/module.c (m4_set_module_builtin_table)
7199 (m4_set_module_macro_table): ...here, and renamed. Changed all
7200 callers.
7201 * m4/m4module.c (m4_module_data): This...
7202 * m4/m4private.c (struct m4_module_data): ...and this...
7203 * m4/module.c (module_data) ...consolidated here and no longer
7204 exported. Changed all callers.
7206 2003-06-16 Gary V. Vaughan <gary@gnu.org>
7208 Begin work on lifting the curse of the global variables. To start
7209 with create a `struct m4' context container, and replace
7210 `m4__symtab' with `context->symtab' throughout. This means
7211 initialising a context container in main, and adjusting many
7212 functions between main and the module entry points so that the
7213 container gets passed through. It would have been nice to
7214 defer this until after 1.5, but it has a major effect on the
7215 user's module writing ABI, so it needs to be addressed now - at
7216 least in the areas that impact the ABI. An interrelated change
7217 in the symtab API removes the dependency on a global symbol table,
7218 and instead focuses on a passed table (from the context
7219 container).
7221 * TODO: Reminders for finishing context functionality.
7222 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
7223 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
7224 global variables and eventually allow m4 to be reentrant.
7225 * m4/m4private.h (m4): Define the new structure here...
7226 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
7227 don't carry the overhead of a function call.
7228 * m4/m4module.h: Prototype extern functions from m4/m4.c.
7229 (m4): Declare type for new struct m4 objects.
7230 (M4SYMTAB): User macro to ease finding the symbol table for the
7231 current context for module developers.
7232 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
7233 verb.
7234 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
7235 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
7236 (m4_call_macro, m4_dump_symbols, m4_expand_input)
7237 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
7238 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
7239 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
7240 m4* context parameter. Changed definitions and all callers.
7241 (m4_symtab): Alias for m4_hash to decouple the
7242 m4_symtab api from m4_hash.
7243 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
7244 m4_hash.
7245 (m4_symtab_create): New function to return an initialised
7246 m4_symtab.
7247 (m4_symtab_delete): New function to delete an m4_symtab's memory.
7248 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
7249 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
7250 instead of simply using the global m4__symtab. Changed
7251 definitions and all callers.
7252 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
7253 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
7254 * src/main.c (main): Create a context and use that instead of the
7255 former global m4__symtab.
7257 2003-06-13 Gary V. Vaughan <gary@gnu.org>
7259 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
7260 to the callback. Callbacks should not need to hardcode the
7261 hashtable they are working from, nor should we have to waste the
7262 userdata parameter to pass the table in.
7263 * m4/hash.h (m4_hash_apply_func): Require the initial table
7264 parameter.
7265 * m4/symtab.c (symtab_destroy): Use the passed table instead
7266 of hardcoding m4__symtab.
7267 (m4_symbol_popdef): Don't use the userdata parameter to pass the
7268 table to arg_destroy.
7269 (arg_destroy): Use the hash parameter, ignore userdata.
7270 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
7271 prototype.
7272 (traceon, traceoff): Call set_trace with the extra initial
7273 parameter.
7275 2003-06-13 Gary V. Vaughan <gary@gnu.org>
7277 More refactoring to stabilise the module api, this time for
7278 symtab.c. Additionally, start to pay attention to function names
7279 that don't contain a verb like they should.
7281 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
7282 wrapper for m4_hash_apply to decouple the symtab module from the
7283 hash module.
7284 (m4_symbol_builtin, m4_symbol_macro): Renamed to
7285 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
7286 callers.
7287 (m4_symbol_delete): Create a macro version to save a function
7288 call.
7289 (m4_token_t, m4_data_t): These violate the POSIX reserved
7290 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
7291 all callers.
7292 (m4_token_type): Renamed to m4_token_get_type.
7293 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
7294 (m4_symtab_exit): Removed from the exported module
7295 api...
7296 * m4/m4private.h (m4__symtab, m4__symtab_init)
7297 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
7298 renamed and added to the internal api. Changed all callers.
7299 (m4_symtab_apply): A faster macro version of the function for
7300 users of the internal api.
7301 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
7302 symbol_destroy and arg_destroy.
7303 (symtab_debug): Added a prototype.
7304 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
7305 so that callers in this file get the faster macro versions from
7306 m4/m4private.h.
7308 2003-06-12 Gary V. Vaughan <gary@gnu.org>
7310 Refactoring modules to rationalise the API into an external
7311 documented (eventually!) API for use by modules in the `m4_'
7312 namespace declared in m4/m4module.h, an internal API between the
7313 source files we ship (including our shipped modules) in the `m4__'
7314 namespace declared in m4/m4private.h and making the rest as
7315 cohesive as possible with liberal use of the `static' keyword.
7316 This change represents an audit to m4/module.c along these
7317 guidelines.
7319 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
7320 Removed. No longer used.
7321 (m4_module_close): Removed prototypes.
7322 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
7323 from the exported module api...
7324 * m4/m4private.h (m4__module_init, m4__module_open)
7325 (m4__module_exit): ...and renamed and added to the internal api.
7326 Changed all callers.
7327 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
7328 Centralised definitions after renaming...
7329 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
7330 (M4_FINISH_SYMBOL): ...and removing from here.
7331 (m4_module_dlerror, m4_module_remove, m4_module_close)
7332 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
7333 module_remove, module_close and caller_id.
7334 (MODULE_SELF_NAME): New macro to make reporting self errors
7335 easier.
7336 (m4_module_load, module_close, module_remove): Use it.
7337 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
7338 name.
7339 * src/main.c (main): Use it.
7341 2003-06-12 Gary V. Vaughan <gary@gnu.org>
7343 * README: Remove references to --enable-changeword, which has been
7344 removed from the code.
7346 2003-06-11 Gary V. Vaughan <gary@gnu.org>
7348 Getting rid of the annoying bug with configure --enable-debug,
7349 which spewed -e: command not found errors. This was an interaction
7350 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
7351 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
7352 branch-1-5) to get the full fix.
7354 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
7355 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
7356 and then use the probed value of $SED.
7357 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
7358 this, it messes up the AC_REQUIRE stack.
7360 2003-06-10 Gary V. Vaughan <gary@gnu.org>
7362 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
7363 the destroy callback.
7364 (m4_arg_destroy): Use the hash address to free the hash node key
7365 field.
7367 2003-06-06 Gary V. Vaughan <gary@gnu.org>
7369 First cut at formal parameters in macros.
7371 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
7372 * m4/xstrzdup.c: New file.
7373 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
7374 associative array of parameter names to details.
7375 (m4_symbol_token): Capture macro names with parameter lists.
7376 (m4_arg_signature_parse): And build an associative array to hang
7377 from the symbol structure to map names to details.
7378 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
7379 m4_hash_resize idiom. Now that we potentially add a little hash
7380 table to many of the entries in the symbol table, added an extra
7381 arg to set the initial size. Changed all callers.
7382 (m4_hash_apply): New function that is basically a generalised
7383 version of...
7384 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
7385 all callers to call m4_hash_apply instead.
7386 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
7387 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
7388 m4_arg_signature association that might be attached to the symbol,
7389 * m4/hash.h (m4_hash_apply_func): Replacement type for...
7390 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
7391 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
7392 parameter lists.
7393 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
7394 (M4_IS_IDENT): Detect characters that can be safely used in
7395 parameter names.
7396 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
7397 * m4/macro.c: Corrected grammar in some comments. Use `token'
7398 rather than `td' for m4_token variables.
7399 (m4_process_macro): If we find a dollar followed by some
7400 M4_IS_IDENT characters, replace that with the contents of the argv
7401 entry with offset stored in the m4_token_arg associated with the
7402 collected identifier.
7404 2003-06-05 Gary V. Vaughan <gary@gnu.org>
7406 Begin preparations for supporting formal parameters in m4 macros.
7408 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
7409 the details of a formal parameter.
7410 (m4_token): Add an arg_signature member to hold a hash table for
7411 looking up formal parameters.
7412 * m4/input.c: Update more bitrotted comments.
7413 (m4_push_builtin): Initialise arg_signature member.
7414 (init_builtin_token): Copy arg_signature member.
7415 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
7416 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
7417 replace...
7418 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
7419 (m4_macro_pushdef, m4_macro_define): ...these, And...
7420 (m4_symbol_token): ...wrapped around this new function, which
7421 vastly simplifies the arguments required by the functions it
7422 replaces.
7423 Changed all callers.
7425 2003-06-05 Gary V. Vaughan <gary@gnu.org>
7427 * m4/macro.c: Format changes.
7429 2003-06-04 Gary V. Vaughan <gary@gnu.org>
7431 * m4/input.c: Updated various bitrotted comments.
7432 (m4_push_builtin): Just pass the whole m4_token, rather than
7433 extracting all the fields in the caller. This also allows us to
7434 check the token type for consistency.
7435 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
7436 Renamed to builtin_funcs, builtin_peek, builtin_read,
7437 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
7438 the code. Changed all callers.
7439 (struct input_block): Similarly renamed u_m member to u_b, and
7440 changed all callers.
7441 (m4_next_token): Use bzero to initialise the data fields.
7442 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
7444 2003-05-29 Gary V. Vaughan <gary@gnu.org>
7446 These changes were necessary to get m4 to build on my iBook
7447 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
7448 (GCC) 3.1 20020420 (prerelease)":
7450 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
7451 inclusion of module loader headers.
7452 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
7453 * m4/Makefile.am: Ditto.
7454 (libm4_la_LIBADD): Added $(LTLIBINTL).
7455 * m4/utility.c (program_name): Removed declaration in favour of
7456 the one already in error.c!
7457 * m4/m4module.h (program_name): Define to program_invocation_name
7458 when using GNU C library. Use an explicit extern declaration.
7459 (interactive, sync_output, debug_level, hash_table_size)
7460 (no_gnu_extensions, prefix_all_builtins, max_debug_argument_length)

7469 (m4_current_line, m4_current_diversion, m4_output_current_line):
7470 Don't rely on default, use an explicit extern.
7471 * m4/error.h (error, error_at_line, error_print_progname)
7472 (error_message_count, error_one_per_line): Ditto.
7473 * m4/ltdl.c: Update from CVS libtool.
7474 * m4/ltdl.h: Ditto.
7475 * commit: Update from CVS cvs-utils.
7477 2002-11-04 gettextize <bug-gnu-gettext@gnu.org>
7479 * po/Makefile.in.in: Upgrade to gettext-0.11.5.
7480 * po/boldquot.sed: New file, from gettext-0.11.5.
7481 * po/en@boldquot.header: New file, from gettext-0.11.5.
7482 * po/en@quot.header: New file, from gettext-0.11.5.

7485 * po/remove-potcdate.sin: New file, from gettext-0.11.5.
7486 * po/Rules-quot: New file, from gettext-0.11.5.
7488 2002-11-04 Akim Demaille <akim@epita.fr>
7490 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
7491 running m4 itself.
7492 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
7494 2002-11-04 Akim Demaille <akim@epita.fr>
7496 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
7498 2002-11-04 Akim Demaille <akim@epita.fr>
7500 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
7501 used as `external', and Libtool 1.4.3.
7502 (LINGUAS): Remove.
7503 (LTLIBOBJS): Don't play with it.
7504 * intl/: Remove.
7505 * Makefile.am (SUBDIRS): Remove intl.
7506 (ACLOCAL_AMFLAGS): Add -I config.
7507 (EXTRA_DIST): Add config/config.rpath.
7508 * po/LINGUAS: New.
7509 * po/Makevars: New.
7510 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
7512 2002-05-29 Gary V. Vaughan <gary@gnu.org>
7514 Preparations for refactoring syntax tables to allow reverse
7515 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
7516 speed of normal lookups in an array of unsigned short.
7518 * m4/input.c (single_quotes, single_comments, use_macro_escape):
7519 Moved from here...
7520 * m4/m4private.h (m4__single_quotes, m4__single_comments,
7521 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
7522 is for internal symbols which unavoidably pollute the global
7523 namespace, but are not published APIs.
7524 Adjusted all callers.
7525 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
7526 m4_set_comment, m4_set_syntax, set_syntax_internal,
7527 unset_syntax_attribute): Moved from this file...
7528 * m4/syntax.c: New. ...to this file.
7529 Also added an m4_syntax_exit stub for orthogonality.
7530 * src/main.c (main): Use it.
7531 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
7532 * m4/m4module.h: Reformatting. New prototypes.
7534 2002-05-29 Gary V. Vaughan <gary@gnu.org>
7536 * bootstrap (aclocal_apiversion): The aclocal apiversion is
7537 distinct from the automake release number (in that the apiversion
7538 apparently has no micro-version-component).
7539 (aclocal_apilibdir): Use it.
7541 2002-05-28 Gary V. Vaughan <gary@gnu.org>
7543 * m4/hash.c (m4_hash_resize): New function.
7544 * m4/hash.h: Add prototype.
7545 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
7546 benchmarking to find a good value for, say, autoconf. This is
7547 already a little quicker than before for me.
7549 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
7550 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
7551 and reenamed.
7552 * m4/hash.h: Adjust prototypes.
7554 2002-01-22 Akim Demaille <akim@epita.fr>
7556 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
7557 APIVERSION scheme.
7558 * tests/Makefile.am (package.m4): New.
7559 * tests/atlocal.in: Adjust to CVS Autotest.
7560 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
7561 * configure.ac: LIBOBJ is a forbidden string.
7562 Simplify AM_INIT_AUTOMAKE invocation.
7563 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
7564 options.m4.
7566 2002-01-21 gettextize <bug-gnu-utils@gnu.org>
7568 * po/Makefile.in.in: Upgrade to gettext-0.10.40.
7570 2001-10-19 Akim Demaille <akim@epita.fr>
7572 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
7574 2001-10-19 Akim Demaille <akim@epita.fr>
7576 * m4/input.c (m4_next_token): Display where was opened what is
7577 not closed.
7579 2001-10-19 Akim Demaille <akim@epita.fr>
7581 * m4/macro.c (expand_argument): Display where was opened what is
7582 not closed.
7584 2001-10-18 Akim Demaille <akim@epita.fr>
7586 * m4/input.c, modules/m4.c: Formatting changes.
7588 2001-10-17 Gary V. Vaughan <gary@gnu.org>
7590 * bootstrap: s/configure.in/configure.ac/
7592 2001-10-16 Gary V. Vaughan <gary@gnu.org>
7594 * m4/symtab.c (m4_symbol_destroy): This function calls
7595 m4_symbol_popdef, which recycles a symbols memory when the last
7596 definition is popped. Since we were passing the address of the
7597 symbol name found in the symbol table, and it was being removed
7598 partway through m4_symbol_destroy() we were referencing freed
7599 memory for the balance of the function. Now we take a copy of the
7600 symbol name tring and use that as a key into the symbol
7601 table... that way if the original symbol name is freed, the copy
7602 is still valid.
7604 2001-10-13 Akim Demaille <akim@epita.fr>
7606 * m4/ltdl.c: Update.
7608 2001-10-13 Akim Demaille <akim@epita.fr>
7610 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
7611 Don't gettextize internal error messages.
7613 2001-10-13 Akim Demaille <akim@epita.fr>
7615 * tests/macros.at (Arity and defn): New failing test.
7616 (Arity, defn, and freeze): New.
7618 Fix `Arity and defn'.
7620 * m4/input.c (m4_push_macro): Don't forget the arity.
7621 * modules/m4.c (defn): Likewise.
7623 2001-10-13 Akim Demaille <akim@epita.fr>
7625 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
7626 to...
7627 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
7628 (Propagation of traceon, Propagation of --trace): this new file.
7630 2001-10-13 Akim Demaille <akim@epita.fr>
7632 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
7633 interface instead of (name, argc...).
7634 Upon failure, specify which argument was guilty.
7635 Adjust callers.
7637 2001-10-13 Akim Demaille <akim@epita.fr>
7639 * modules/evalparse.c: Save translators' time: don't translate
7640 internal error messages.
7641 (m4_evaluate): Simplify/normalize error messages.
7642 * doc/m4.texinfo (Eval): Adjust.
7644 2001-10-13 Akim Demaille <akim@epita.fr>
7646 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
7647 where no checking is needed.
7648 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
7649 interface instead of (name, argc...).
7650 Adjust callers.
7651 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
7652 elsewhere.
7654 2001-10-13 Akim Demaille <akim@epita.fr>
7656 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
7657 exclude the builtin name from the count.
7658 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
7659 calling ifelse with a single argument is valid.
7660 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
7661 with 1 and 2 args, mostly to strengthen the test suite.
7663 2001-10-13 Akim Demaille <akim@epita.fr>
7665 * m4/output.c (m4_make_diversion, m4_insert_file)
7666 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
7668 2001-10-12 Gary V. Vaughan <gary@gnu.org>
7670 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
7671 since we call these things builtins in the rest of the code!
7673 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
7675 2001-10-12 Gary V. Vaughan <gary@gnu.org>
7677 Rather than forcing each builtin definition to manage its own
7678 argument range checking, tabulate the maxima and minima for all
7679 builtins in each module. This forces us to consider what the
7680 valid ranges for each builtin should be, and moves the checking
7681 code out of each builtin implementation and into the builtin
7682 caller infrastructure.
7684 * m4/m4module.h (struct m4_builtin): Add argument minima and
7685 maxima.
7686 * m4/m4private.h (struct m4_token): Reflect them here too.
7687 * m4/input.c (struct input_block): ...and here.
7688 (m4_token_copy): New function for token copying.
7689 (init_macro_token): Copy them from a token to the input stack.
7690 (m4_next_token): Don't forget to initialise them for text
7691 macros.
7692 * m4/macro.c (expand_argument): Use m4_token_copy, and also
7693 check argument counts before calling the builtin handler.
7694 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
7695 (m4_symbol_macro): Likewise.
7696 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
7697 parameters. Updated all callers.
7698 (m4_builtin_define): Ditto.
7699 (m4_macro_pushdef, m4_macro_define): Ditto.
7700 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
7701 * modules/evalparse.c: Declare argument counts for defined
7702 builtins and remove explicit calls to m4_bad_argc().
7703 * modules/gnu.c: Ditto.
7704 * modules/load.c: Ditto.
7705 * modules/m4.c: Ditto.
7706 * modules/modtest.c: Ditto.
7707 * modules/mpeval.c: Ditto.
7708 * modules/perl.c: Ditto.
7709 * modules/shadow.c: Ditto.
7710 * modules/stdlib.c: Ditto.
7711 * modules/time.c: Ditto.
7712 * TODO: Updated.
7714 2001-10-10 Gary V. Vaughan <gary@gnu.org>
7716 The trace semantics now attach the trace bit to a symbol name.
7717 For as long as a traceon(`foo') is active, calls to foo will be
7718 traced regardless of intervening undefines or module unloads.
7719 Fixed the flag propogation issues differently to the fixes
7720 reverted with the last attempt at nailing down trace:
7722 * m4/m4private.h: This file is not visible outside of the m4
7723 source tree, so I removed all the `M4_' and `m4_' prefixes to save
7724 on typing. Updated all clients.
7725 (m4_token): New typedef contains the fields that need to be passed
7726 around with the low level tokeniser.
7727 (m4_token_data): Removed.
7728 (m4_symbol): Now contains the traced flag again.
7729 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
7730 the trace bit set. This change is contained entirely within this
7731 module and doesn't leak out into the callers. Updated all
7732 clients.
7733 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
7734 new fields in m4_token. Updated all clients.
7735 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
7736 that `groks_macro_args' and `blind_if_no_args' flags are retained
7737 when defn() results are passed around in m4 code. Updated all
7738 callers.
7739 (m4_builtin_define): Ditto.
7740 (m4_macro_pushdef, m4_macro_define): Ditto.
7741 * m4/input.c (struct input_block): Add a flags field to facilitate
7742 the above.
7743 (m4_push_macro): ...use it.
7744 (init_macro_token): Retrieve it.
7745 (m4_next_token): Initialise it.
7746 * m4/macro.c (expand_argument): Copy it.
7747 * m4/m4module.h: Adjust.
7748 * tests/builtins.at: Adjust the expected output of the trace
7749 tests to reflect the change in semantics.
7750 * tests/modules.at (modules: trace): Check that unloading a
7751 module which supplies a traced symbol definition doesn't lose te
7752 trace bit.
7754 2001-10-07 Gary V. Vaughan <gary@gnu.org>
7756 * modules/gnu.c (m4_macro_table): Display the timetamp when
7757 expanding __m4_version__.
7759 * configure.ac (--with-modules): Forgot a comma in the
7760 AC_HELP_STRING parameter list.
7762 2001-10-05 Gary V. Vaughan <gary@gnu.org>
7764 * bootstrap: Remove aclocal.m4t when it is no longer required.
7766 2001-10-05 Akim Demaille <akim@epita.fr>
7768 * tests/Makefile.am: Adjust for gnuprog2.
7769 * tests/m4.in: There can be a leading path.
7770 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
7771 * tests/testsuite.at: Adjust to the most recent Autotest.
7772 (AT_CHECK_M4_FILTER): Fix and rename as...
7773 (AT_TEST_M4): this.
7774 * tests/others.at: Use it.
7776 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
7777 variable in shell scripts, one uses `$'...
7779 2001-10-04 Gary V. Vaughan <gary@gnu.org>
7781 * configure.ac: `rm -f $m4_getopt_h' was lost.
7783 2001-10-04 Gary V. Vaughan <gary@gnu.org>
7785 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
7786 time. Define it for config.h in order to...
7787 * src/main.c (main): ...display the timestamp for --version.
7789 2001-10-04 Akim Demaille <akim@epita.fr>
7791 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
7792 previous builtins `regexp' and `patsubst'.
7793 (regexp, patsubst): Use them.
7794 (eregexp, epatsubst): New builtins.
7795 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
7796 (Epatsubst and Patsubst, Eregexp and Regexp): these.
7797 (Extensions): More info on REs.
7799 2001-10-04 Akim Demaille <akim@epita.fr>
7801 * modules/modtest.c (init_handler): Consistently output to stderr.
7802 (finish_handler): New.
7803 (test): The `if' is an `assert'.
7804 * tests/modules.at: Adjust.
7806 2001-10-04 Akim Demaille <akim@epita.fr>
7808 * m4/utility.c (m4_bad_argc): Detail the mismatches.
7810 2001-10-01 Akim Demaille <akim@epita.fr>
7812 * tests/generate.awk: Tag the tests with `documentation'.
7813 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
7814 Use the make the existing modtest tests more uniform, and complete
7815 the set of possibilities.
7817 2001-10-01 Akim Demaille <akim@epita.fr>
7819 * config/gmp.m4: Consult the user before using GMP: use
7820 --without-gmp.
7821 * configure.ac: Adjust.
7822 * modules/gmp.c: No protection needed as the module is not built
7823 if GMP is not used.
7825 2001-10-01 Akim Demaille <akim@epita.fr>
7827 * tests/generate.awk: Remove debugging code.
7828 (fatal): Specify the current location.
7830 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
7831 * modules/gnu.c, modules/m4.c: Use M4ARG.
7833 2001-10-01 Akim Demaille <akim@epita.fr>
7835 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
7836 (m4_regexp_compile): New.
7837 (regexp, patsubst): Use it.
7839 2001-09-30 Gary V. Vaughan <gary@gnu.org>
7841 Reinstate the memory handling improvements from the patch I just
7842 reverted. Relevant ChangeLog entries repeated here:
7844 * m4/module.c (m4_module_remove): New function that holds the core
7845 of the old m4_module_unload.
7846 (m4_module_unload): Use it.
7847 (m4_module_unload_all): When we know the modules will never be
7848 used again (i.e. on exit), free up as much module memory as
7849 possible. There are still some artifacts from resident modules
7850 living inside ltdl.c, but everything else is freed.
7851 * m4/debug.c (m4_debug_exit): Free memory allocated in
7852 m4_debug_init().
7853 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
7854 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
7855 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
7856 * m4/m4module.h: Updated prototypes.
7857 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
7858 * m4/hash.h: Updated prototypes.
7859 * src/main.c (main): Use all these new functions to clean up as
7860 much memory as possible before exit.
7862 2001-09-30 Gary V. Vaughan <gary@gnu.org>
7864 Reverted my large patch for removing the old m4_symbol
7865 structure on 2001-09-20. We are still not happy about the way
7866 trace works in conjunction with defn and undefine, and leaving
7867 the reverted patch active prevents us from moving the traced
7868 bit from the definition back to the symbol.
7870 2001-09-30 Gary V. Vaughan <gary@gnu.org>
7872 * configure.in: Moved to...
7873 * configure.ac: ...here. Added a libtool like timestamped
7874 banner, and tidied up the libltdl cruft.
7875 * config/mkstamp: Script to extract a timestamp from ChangeLog.
7876 * modules/Makefile.am (INCLTDL): Removed. This is required
7877 only when libltdl is configured in a subdirectory.
7878 * src/Makefile.am: Ditto.
7879 (LIBADD_DL): No need to add this again, libtool already knows
7880 that libm4.la depends on it.
7881 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
7882 them.
7884 * TODO: stackovf.c is basically broken.
7885 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
7887 2001-09-28 Akim Demaille <akim@epita.fr>
7889 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
7891 2001-09-27 Akim Demaille <akim@epita.fr>
7893 * tests/m4.in: Don't use short options.
7894 Simplify the stderr signature normalization.
7896 2001-09-27 Akim Demaille <akim@epita.fr>
7898 tests/m4 shall be position independent.
7900 * tests/m4.in: New.
7901 * tests/m4: Remove.
7902 * tests/testsuite.at: No args to AT_INIT.
7903 * configure.in, tests/Makefile.am: Adjust.
7905 2001-09-22 Akim Demaille <akim@epita.fr>
7907 Autotest has changed again.
7909 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
7910 (package.m4): Remove.
7911 * configure.in: Adjust to LIBADD_GMP.
7913 2001-09-21 Gary V. Vaughan <gary@gnu.org>
7915 * config/gmp.m4 (AC_ARG_WITH): Removed.
7916 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
7917 (AC_LIB_GMP): When performing a test compile against libgmp,
7918 include the header gmp.h if possible, and link against -lgmp. If
7919 they both work define USE_GMP.
7920 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
7921 (mpeval_LTX_init_func): Complain on load that there was no libgmp
7922 at compile time.
7924 2001-09-20 Gary V. Vaughan <gary@gnu.org>
7926 * m4/evalparse.c: Moved to...
7927 * modules/evalparse.c: ...here. This code is shared between
7928 modules/mpeval.c and modules/m4.c, so there is no need to pollute
7929 the libm4 API with its details. Moderately rewritten to interface
7930 into its clients more simply.
7931 * m4/eval.c: Deleted. Migrated functionality to...
7932 * modules/m4.c: ...here.
7933 (builtin_eval): Implemented in terms of the new interface style.
7934 * modules/mpeval.c (builtin_mpeval): Ditto.
7935 * m4/m4module.h: Removed references to the former m4/eval.c.
7936 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
7937 (EXTRA_libm4_la_SOURCES): Deleted.
7938 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
7939 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
7941 2001-09-20 Akim Demaille <akim@epita.fr>
7943 * config/gmp.m4 (AM_WITH_GMP): Rename as...
7944 (AC_LIB_GMP): this.
7945 By default, use gmp.
7946 Massive revamping.
7947 * configure.in: Adjust.
7948 Use Automake conditionals for USE_GMP.
7949 Always compute sizeof (long long int).
7950 This was a bug BTW, as `eval' (not `mpeval') depends on it:
7951 before, it was used _only_ if mpeval was not activated.
7952 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
7953 (mpeval_la_LIBADD): New macros.
7954 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
7955 Indent.
7956 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
7957 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
7958 WITH_GMP.
7960 2001-09-20 Akim Demaille <akim@epita.fr>
7962 * tests/Makefile.am (package.m4): New.
7963 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
7965 2001-09-20 Gary V. Vaughan <gary@gnu.org>
7967 More cleanup. After the last patch, m4_symbol holds nothing but
7968 the head of a chain of m4_token_data. So I have removed the old
7969 m4_symbol, so that m4_token_data chains are stored directly in the
7970 value cell of a hash table node. But there's more... m4_symbol
7971 was a more natural name for the symbol value cell, and now that it
7972 is gone I have renamed the former m4_token_data structure to
7973 m4_symbol. This change turned out to be a pig to get right, since
7974 the original code didn't need to modify the value cell itself,
7975 since changing the chain happened inside the m4_symbol that used
7976 to be returned -- I had to pass the address of the value cell
7977 across various function calls, incase the head value changed. I
7978 also tightened up the memory management to help me find a nasty
7979 memory corruption bug that took me all night to track down...
7981 * m4/m4private.h (struct m4_symbol): Removed.
7982 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
7983 all references.
7984 * m4/hash.c (m4_hash_iterator_value): Return the address of the
7985 value cell. Updated all callers.
7986 * m4/symtab.c: Took advantage of the simplification in the data
7987 structures to rewrite a lot of this file more simply. There is
7988 still some room for optimisation here, but we should tackle that
7989 systematically closer to the release.
7991 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
7992 revealed. This version is ahead of CVS libtool until I get chance
7993 to flush my changes.
7994 * m4/module.c (m4_module_remove): New function that holds the core
7995 of the old m4_module_unload.
7996 (m4_module_unload): Use it.
7997 (m4_module_unload_all): When we know the modules will never be
7998 used again (i.e. on exit), free up as much module memory as
7999 possible. There are still some artifacts from resident modules
8000 living inside ltdl.c, but everything else is freed.
8001 * m4/debug.c (m4_debug_exit): Free memory allocated in
8002 m4_debug_init().
8003 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
8004 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
8005 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
8006 * m4/m4module.h: Updated prototypes.
8007 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
8008 * m4/hash.h: Updated prototypes.
8009 * src/main.c (main): Use all these new functions to clean up as
8010 much memory as possible before exit.
8012 2001-09-18 Gary V. Vaughan <gary@gnu.org>
8014 The `traced' flag needs to be attached to the definition of a
8015 symbol rather than the current symbol containing the definition.
8016 Implementing this showed up some long standing post 1.4 bugs in
8017 flag propogation which I also fixed.
8019 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
8020 (struct m4_token_data): And add it back in here.
8021 * m4/input.c (init_macro_token): Propogate the traced flag
8022 correctly.
8023 * m4/macro.c (expand_argument): Ditto.
8024 * tests/builtins.at (trace2, trace3): New tests based on Akim's
8025 sadistic email ;-)
8027 2001-09-08 Gary V. Vaughan <gary@gnu.org>
8029 * m4/m4private.h (struct m4_token_data): Simplified by removing
8030 the redundant `traced' flag, and one level of structure nesting.
8031 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
8032 * m4/input.c (init_macro_token): No need to initialise removed
8033 `traced' field.
8034 * m4/macro.c (expand_argument): No need to copy it either.
8035 * m4/utility.c (m4_token_data_func_traced): Or provide an access
8036 function.
8038 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
8039 dependant on multiple symbols with the same key, so preserving
8040 relative symbol order in each bucket during resizing is no longer
8041 required. The resize function is considerably faster as a result.
8043 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
8044 s/m4_symbol_insert/m4_symbol_define/g;
8045 s/m4_builtin_insert/m4_builtin_define/g;
8046 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
8048 2001-09-08 Gary V. Vaughan <gary@gnu.org>
8050 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
8051 commits, the m4_lookup_symbol dispatch function is split into
8052 specialised functions that must be called directly.
8054 * m4/m4module.h (m4_symbol_lookup_t): Removed.
8055 * m4/symtab.c (m4_lookup_symbol): Removed.
8056 (m4_symbol_builtin, m4_symbol_macro): New functions.
8057 * m4/builtin.c (m4_builtin_define): Split into...
8058 (m4_builtin_pushdef, m4_builtin_insert): ...these.
8059 (m4_macro_define): Split into...
8060 (m4_macro_pushdef, m4_macro_insert): ...these.
8061 * src/main.c (main): Set command line macros from `-D' parameters
8062 using `m4_macro_define'.
8064 2001-09-08 Gary V. Vaughan <gary@gnu.org>
8066 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
8067 this from m4_remove_table_reference_symbols().
8068 * m4/m4module.h, m4/module.c: Updated all references.
8070 2001-09-07 Akim Demaille <akim@epita.fr>
8072 * modules/stdlib.c, modules/times.c: Misc cleanups.
8074 2001-09-07 Akim Demaille <akim@epita.fr>
8076 * configure.in: We now need Autoconf 2.52e.
8077 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
8078 and `M4_SYMBOL_DELETE'.
8079 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
8080 * src/main.c (main): Adjust.
8082 2001-09-06 Gary V. Vaughan <gary@gnu.org>
8084 Fix the obstack.h problem once and for all! At configure time we
8085 can test for a system supplied obstack.h: depending on the
8086 result, we now generate system.h with an #include of the correct
8087 header. As a bonus, I've also added a --with-included-obstack,
8088 incase the user doesn't like the system obstack for some
8089 reason... and also we can test the shipped obstack on a system
8090 that has oe of its own. We also now need to be careful to add
8091 build directories to the include search path, since the generated
8092 system.h will be in the build tree.
8094 * configure.in (AC_CONFIG_FILES): Generate system.h from
8095 system-h.in.
8096 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
8097 include the system obstack header or the copy shipped with M4.
8098 Allow the user to override configure and force the build to use
8099 the shipped version.
8100 * m4/system-h.in: New file, template for...
8101 * m4/system.h: ...this. Now deleted.
8102 * m4/m4module.h: Include system.h before everything else.
8103 * src/freeze.c: Ditto.
8104 * m4/Makefile.am (dist-hook): Remove generated system.h.
8105 (INCLUDES): Check builddir for generated headers before checking
8106 srcdir.
8107 * modules/Makefile.am (INCLUDES): Ditto.
8108 * src/Makefile.am (INCLUDES): Ditto.
8110 2001-09-05 Gary V. Vaughan <gary@gnu.org>
8112 * TODO: Remove the items that have been addressed already.
8114 2001-09-05 Akim Demaille <akim@epita.fr>
8116 * src/main.c (main): Standardize --version.
8118 2001-09-05 Akim Demaille <akim@epita.fr>
8120 * modules/format.c (format): Have a bigger `str'.
8122 2001-09-05 Akim Demaille <akim@epita.fr>
8124 Rationalize warnings, reporting the macro name as if it were a
8125 program name, and assertions.
8127 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
8128 (M4WARN): New.
8129 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
8130 (m4_symbol_delete):
8131 Use assert for internal errors.
8132 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
8133 M4WARN.
8134 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
8135 M4WARN and assert.
8136 * tests/builtins.at (pushpop): Adjust.
8138 2001-09-05 Akim Demaille <akim@epita.fr>
8140 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
8141 with pointers.
8143 2001-09-05 Akim Demaille <akim@epita.fr>
8145 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
8146 * m4/macro.c, m4/symtab.c: Adjust.
8148 2001-09-05 Akim Demaille <akim@epita.fr>
8150 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
8151 (m4_symbol_pop, m4_symbol_del): this.
8152 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
8153 (m4_symbol_popdef, m4_symbol_delete): New.
8154 (m4_lookup_symbol): Adjust.
8155 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
8157 2001-09-05 Akim Demaille <akim@epita.fr>
8159 * m4/m4module.h (m4_symbol_lookup): Rename as...
8160 (m4_symbol_lookup_t): this.
8162 2001-09-05 Akim Demaille <akim@epita.fr>
8164 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
8165 unused.
8166 * m4/symtab.c (m4_lookup_symbol): Adjust.
8168 2001-09-03 Gary V. Vaughan <gary@gnu.org>
8170 Bootstrap will now work with Libtool 1.4.1 or higher:
8171 * bootstrap: Remove stale autom4te.cache files when
8172 rebootstrapping.
8173 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
8174 libtool.m4.
8175 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
8176 libtool.m4 directly.
8177 Run libtoolize to refresh ltmain.sh.
8178 * config/ltmain.sh: Deleted.
8179 * acinclude.m4: Deleted.
8180 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
8182 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
8183 implementation for the cvs impaired libtool user.
8185 2001-09-03 Akim Demaille <akim@epita.fr>
8187 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
8188 internal errors.
8189 Avoid using `default' in switch, as it hides useful compiler
8190 warnings when a case is forgotten.
8192 2001-09-03 Akim Demaille <akim@epita.fr>
8194 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
8195 is no such thing as `WITH_MODULES'.
8197 2001-09-03 Akim Demaille <akim@epita.fr>
8199 Improve the test suite's selfcontainedness.
8201 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
8202 (Include, Undivert): Tag the other input files.
8203 * tests/generate.awk: Catch `@comment file:'.
8204 `-I $src' is no longer needed.
8205 `next' is really like `return': the rest is skipped.
8206 Adjust to `input.m4'.
8207 (fatal): New function.
8208 * tests/foo, tests/incl.m4: Remove.
8210 2001-09-01 Gary V. Vaughan <gary@gnu.org>
8212 The shadowing mechanism and, infact, the whole symbol table
8213 implementation was creaking under the weight of the features piled
8214 on top of it. We now have a separate hash table module which will
8215 dynamically resize to keep symbol density withing good performace
8216 limits, and a new symtab module layered above it. Symbol lookups
8217 are now marginally more efficient (since the shadowed flag is no
8218 longer required) and symbol removal, such as on module unload, is
8219 considerably faster due to a reorganisation of the data structures
8220 used in symtab.c.
8222 * src/main.c (main): Don't mention `-H'.
8223 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
8224 effect.
8225 * NEWS: Updated.
8226 * m4/hash.c: New generalised dynamic hash table data structure
8227 management module.
8228 * m4/hash.h: Public interface.
8229 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
8230 (libm4_la_SOURCES): Add hash.c.
8231 * m4/symtab.c: More or less rewritten from scratch, within the
8232 bounds of the previous API.
8233 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
8234 call. Updated all callers.
8235 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
8236 declarations to reflect API changes.
8237 (M4INIT): Generate a declaration too, to avoid the warning with
8238 --enable-debug builds.
8239 (M4FINISH): Ditto.
8240 (HASHMAX): Removed.
8241 * m4/utility.c (hash_table_size): Removed.
8242 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
8243 names, which are then looked up by builtin_dumpdef() as necessary.
8244 This implies a small speedup in builtin_symbols(), which discarded
8245 all of the symbol info under the old call.
8246 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
8247 shadowing is implicit in respect to the new data structures.
8248 symbol names are no longer duplicated here, they are stored in the
8249 key field of the hash table.
8250 Moved macro_args and blind_no_args...
8251 (m4_token_data): ...to here.
8252 m4/macro.c (expand_macro): Added a name argument since the symbol
8253 name is no longer copied into each struct m4_symbol. Modified all
8254 callers.
8255 (collect_arguments): Ditto.
8256 * modules/m4.c (set_trace): Ditto.
8257 * modules/gnu.c (builtin_symbols): Updated.
8258 * src/freeze.c (produce_symbol_dump): Much improved in light of
8259 the improved symbol table layout.
8261 2001-09-01 Gary V. Vaughan <gary@gnu.org>
8263 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
8264 to M4_SYMBOL_NEXT.
8265 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
8266 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
8267 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
8268 SYMBOL_HANDLE): Ditto.
8269 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
8270 modules/gnu.c, modules/m4.c, src/freeze.c,
8271 src/main.c: Updated all references.
8273 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
8274 Automake 1.5 chokes on dynamic source file lists, Besides, it is
8275 already listed in m4_LDADD... how did that ever used to work?
8276 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
8277 link.
8278 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
8279 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
8281 * tests/m4: Don't call the m4 wrapper script with libtool, it
8282 works fine all by itself.
8284 2001-08-30 Gary V. Vaughan <gary@gnu.org>
8286 The experimental `changeword' feature never took off, and has
8287 no obvious advantages over `changesyntax' to compensate the
8288 enormous speed penalty it carries:
8289 * configure.in (ENABLE_CHANGEWORD): Removed.
8290 * m4/m4module.h (m4_set_word_regexp): Removed.
8291 * m4/m4private.h (m4_token_data): Removed original_text field.
8292 * m4/utility.c (m4_token_data_orig_text): Removed.
8293 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
8294 * m4/macro.c: Ditto.
8295 * src/main.c: Ditto.
8296 * modules/Makefile.am (changeword.la): Removed.
8297 * modules/changeword.c: File removed.
8298 * doc/m4.texinfo: References to changeword and --word-regexp
8299 removed.
8300 * po/POTFILES.in: modules/changeword.c removed.
8301 * tests/atlocal.in (ENABLE_CHANGEWORD): Removed.
8302 * tests/builtins.at (changeword): Test removed.
8304 2001-08-30 Akim Demaille <akim@epita.fr>
8306 * bootstrap.sh: Create aclocal.m4 instead of modifying it.
8307 This also help having a single list of m4 files: in
8308 config/Makefile.am.
8309 * config/Makefile.am (STANDARD_MACROS): Rename as...
8310 (ACLOCAL_MACROS): this.
8311 (list-standard-macros): Remove.
8312 (spy): New.
8314 2001-08-29 Gary V. Vaughan <gary@gnu.org>
8316 In an attempt to moderate my egomania...
8317 * tests/modules.at: Remove attributions.
8319 * tests/generate.awk: When making substitutions to "@&t@", either
8320 "&" or "\&" in the substitution string argument to gsub refer back
8321 to the matched text. "@\\&t@" seems to work though, Tests 43 and
8322 67 now pass for me.
8324 2001-08-29 Akim Demaille <akim@epita.fr>
8326 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)
8327 (include, indir, multiquotes, patsubst, pushdef/popdef, regexp)
8328 (sync-lines, trace, translit, undivert, wrap): Move to...
8329 * tests/builtins.at: this new file.
8330 * tests/others.at (Discard comments, import-environment): Move to...
8331 * tests/options.at: this new file.
8333 2001-08-29 Akim Demaille <akim@epita.fr>
8335 * tests/others.at (Freezing modules)
8336 (--module-directory: absolute path, modpath2, modpath3)
8337 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
8338 * tests/modules.at: here, new file.
8339 * tests/others.at, tests/generate.awk: Add a banner.
8340 * tests/testsuite.at: Adjust.
8341 (AT_CHECK_M4_FILTER): New, but unused.
8343 2001-08-29 Akim Demaille <akim@epita.fr>
8345 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
8346 handle that.
8347 * tests/others.at (wrap): Inline wrap.m4.
8348 (shadow): Inline shadow.m4.
8349 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
8350 * tests/m4: Simplify.
8352 2001-08-29 Akim Demaille <akim@epita.fr>
8354 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
8355 --language.
8357 2001-08-29 Akim Demaille <akim@epita.fr>
8359 * tests/generate.awk (normalize): s/@__@/@&t@/.
8361 2001-08-28 Akim Demaille <akim@epita.fr>
8363 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.
8365 2001-08-28 Gary V. Vaughan <gary@gnu.org>
8367 * bootstrap (generate.awk): Generate test cases with new script.
8369 2001-08-27 Akim Demaille <akim@epita.fr>
8371 * tests/Makefile.am (installcheck-local): Don't use
8372 `dc_install_base' which is not visible here, but `exec_prefix'
8373 which is clearly the RT anyway.
8374 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
8375 related to testing a now installed m4.
8376 * tests/m4: Do it here.
8378 2001-08-27 Akim Demaille <akim@epita.fr>
8380 * tests/others.at (indir): Formatting change.
8382 2001-08-27 Akim Demaille <akim@epita.fr>
8384 * tests/Makefile.am (installcheck-local): New.
8385 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
8386 the test suite.
8387 Prefer options over envvars.
8388 * src/main.c (main): First bug caught by the test suite (yeah!):
8389 --batch lacked a `break' which resulted in an accidental
8390 invocation of --discard-comments.
8392 2001-08-27 Akim Demaille <akim@epita.fr>
8394 * tests/others.at (capitalize, changeword, comments, ddivert)
8395 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
8396 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
8397 (sysv-args, trace, translit, undivert): Don't rely on files in
8398 examples/: AT_DATA them.
8400 2001-08-27 Akim Demaille <akim@epita.fr>
8402 Let the test suite use a wrapper around the not installed m4 to
8403 pretend it is (installed).
8405 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
8406 such a way that m4 does not process them.
8407 * configure.in: The package name seems to be `m4', not `M4'.
8408 * tests/m4: New.
8409 * tests/atlocal.in (at_package, M4): Remove.
8410 * tests/testsuite.at, tests/others.at: Use m4, not $M4.
8412 2001-08-27 Akim Demaille <akim@epita.fr>
8414 * tests/Makefile.am (CLEANFILES): Remove.
8415 (DISTCLEANFILES, clean-local): New.
8416 * examples/mktests.sh: Remove.
8418 2001-08-27 Akim Demaille <akim@epita.fr>
8420 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
8421 Don't use aclocal: it's written by hand.
8422 * aclocal.m4: m4_include all the files instead of being built by
8423 aclocal.
8424 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
8425 until it reads the traces by itself.
8426 * configure.in: Require Autoconf 2.42c as we are now using
8427 AC_CONFIG_TESTDIR instead of AT_CONFIG.
8428 Catch unexpanded `jm_' macros.
8429 * config/atconfig.m4: Remove.
8430 * config/error.m4: new.
8431 * config/Makefile.am: Ship the files included by aclocal.m4.
8432 * tests/Makefile.am (TESTSUITE_SOURCES): Rename as...
8433 (TESTSUITE_AT): this, to please Automake.
8434 (TESTSUITE): This target uses autotest/autotest.m4, not
8435 autotest/general.m4.
8436 * tests/testsuite.at: Prereq Autotest 2.52c.
8437 * examples/Makefile.am (pkgdata_DATA): Rename as...
8438 (dist_pkgdata_DATA): this.
8439 * doc/Makefile.am (man_MANS): Rename as...
8440 (dist_man_mans): this.
8442 2001-08-20 Gary V. Vaughan <gary@gnu.org>
8444 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
8445 Robert Collins, building on Cygwin no longer requires Windows
8446 import and export symbol decorations.
8447 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.
8448 * m4/error.h (M4_SCOPE) [cygwin*]: Ditto.
8449 * m4/debug.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.

8455 * m4/xmalloc.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
8456 * configure.in (LIBM4_DLL_IMPORT) [cygwin*]: Don't set this
8457 anymore.
8458 * src/Makefile.am (AM_CPPFLAGS) [cygwin*]: Don't use it either!
8459 * modules/Makefile.am (AM_CPPFLAGS) [cygwin*]: Ditto.
8461 2001-08-20 Gary V. Vaughan <gary@gnu.org>
8463 Ansify the source. Previously we had a mix, where my code was
8464 in a K&R compatible style, and the preexisting code was in ANSI
8465 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
8466 and now the code base is much cleaner.
8468 * m4/system.h: Remove M4_PARAMS macro and all users. Remove
8469 VOID macro and all users.
8470 * m4/m4module.h: Ansify function prototypes and headers.
8471 * m4/builtin.c: Ditto.
8472 * m4/evalparse.c: Ditto.
8473 * m4/input.c: Ditto.
8474 * m4/macro.c: Ditto.
8475 * m4/module.c: Ditto.
8476 * m4/output.c: Ditto.
8477 * m4/path.c: Ditto.
8478 * m4/symtab.c: Ditto.
8479 * m4/utility.c: Ditto.
8480 * modules/format.c: Ditto.

8484 * src/freeze.c: Ditto.
8485 * src/m4.h: Ditto.
8486 * src/main.c: Ditto.
8488 2001-08-20 Akim Demaille <akim@epita.fr>
8490 * config/atconfig.m4: s/EOF/ATEOF/, so that configure can be
8491 generated with stock 2.52.
8493 2001-08-20 Akim Demaille <akim@epita.fr>
8495 * config/atconfig.m4: New, until part of Autoconf per se.
8496 * configure.in (AT_CONFIG): Use it.
8497 Adjust.
8498 * tests/mkconfig.sh, tests/atconfig.in, tests/defs: Remove.
8499 * tests/atlocal.in: New.
8500 * tests/generate.awk: For the time being, the empty quadrigraph is
8501 `@__@'.
8502 * tests/others.at (changeword, gmp): Check the configuration
8503 variable against `yes'.
8504 * tests/testsuite.at (dnl): Allow it, as it's used all over the
8505 place.
8507 2001-08-20 Akim Demaille <akim@epita.fr>
8509 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
8510 * modules/m4.c (undivert): Disable the possibility of undiverting
8511 several files at once: it is not documented, it is inconsistent
8512 with the other macros, it can be straightforwardly mocked by
8513 several invocations, and most importantly, it prevents the
8514 possibility of other kinds of extension.
8515 Use `m4_numeric_arg'.
8517 2001-08-20 Akim Demaille <akim@epita.fr>
8519 * examples/include.m4: Typo.
8520 * tests/generate.awk: Really add it.
8521 * tests/Makefile.am: Adjust.
8522 * tests/others.at (Discard comments): It sure fails without `-c'.
8523 (include, undivert): Add -I examples/.
8525 2001-08-20 Akim Demaille <akim@epita.fr>
8527 Use sprintf, not ecft and friends since it is standard, portable,
8528 simplifies the code, and since the latter is even deprecated
8529 according to the GNU libc documentation.
8531 * modules/format.c: Drop evct support.
8533 2001-08-19 Gary V. Vaughan <gary@gnu.org>
8535 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Cleaned up. Don't test
8536 for `-pipe' here...
8537 * configure.in: ...do it here instead.
8539 * c-boxes.el: Deleted.
8540 * m4/builtin.c: Reformat box comments to be closer to GNU
8541 standards.
8542 * m4/debug.c: Ditto.

8567 * m4/module.c: Fixup some errors in the description comment.
8569 2001-08-17 Akim Demaille <akim@epita.fr>
8571 * tests/others.at (iso8859): Specify the path to the M4 test file.
8572 * tests/testsuite.at (AT_CHECK_M4): Normalize the path of input
8573 files in error messages.
8575 2001-08-17 Akim Demaille <akim@epita.fr>

8578 * tests/others.at: Adjust input files paths.
8579 * tests/atconfig.in: Set top_builddir.

8581 `testsuite' is in src, not build.
8583 2001-08-17 Akim Demaille <akim@epita.fr>
8585 * tests/Makefile.am (EXTRA_DIST): Ship generate.awk.
8586 (generate.at): Install a temporary hack until the actual
8587 generate.awk is added to the repository.
8588 * tests/atconfig.in: New.
8590 2001-08-17 Akim Demaille <akim@epita.fr>
8592 Really apply the patch ``Drop Autoconf 2.13 compatibility.''
8594 2001-08-17 Akim Demaille <akim@epita.fr>
8596 * doc/m4.texinfo: Promote proper quotation.
8598 2001-08-17 Akim Demaille <akim@epita.fr>

8633 * tests/Makefile.am: Adjust.
8635 2001-08-17 Akim Demaille <akim@epita.fr>
8637 others.at no longer depends on other-tests/.
8639 * tests/others.at (stackovf): You're actually...
8640 (sync-lines): this.
8641 (modfreeze, modpath1, modpath2, modpath3, modpath4, modtest, shadow)
8642 (unload.test): Keep their authorship.
8643 (discard-comments, gmp, import-environment, modfreeze)
8644 (sync-lines): Embed the input files.
8645 * tests/stackovf.test: Copy from other-tests/stackovf.test.

8655 * tests/testsuite.at: Adjust.
8656 (AT_CHECK_M4): Don't overquote. Blush...
8658 2001-08-17 Akim Demaille <akim@epita.fr>
8660 Start using Autotest. atconfig creation is still lacking.
8662 * examples/patsubst.m4, modules/modtest.m4, modules/shadow.m4,
8663 * examples/reverse.m4, tests/other-tests/import-environment.m4,
8664 * tests/other-tests/iso8859.m4: Don't produce trailing blanks.
8665 * tests/other-tests/import-environment.test: Don't check LANGUAGE
8666 as it might be `unset', or set to `C'.

8668 * tests/other-tests/modpath2.test, tests/other-tests/modpath3.test,
8669 * tests/other-tests/modpath4.test, tests/other-tests/modtest.test,
8670 * tests/other-tests/patsubst.test, tests/other-tests/reverse.test,
8671 * tests/other-tests/shadow.test: Adjust.
8672 * tests/testsuite.at, tests/others.at: New.
8673 * tests/Makefile.am: Adjust.
8675 2001-08-17 Akim Demaille <akim@epita.fr>
8677 Drop Autoconf 2.13 compatibility.
8679 * configure.in (changeword): No need to undefine it, as anyway if
8680 it's defined, M4sugar moved it as m4_changeword.
8681 And anyway, proper quotation is enough.
8682 (m4_pattern_allow): As it exists in 2.50, just use it.
8683 (AC_OUTPUT): Split in AC_CONFIG_FILES and AC_CONFIG_COMMANDS.
8684 Don't handle Gettext's duties, let it handle them.

8690 (m4_errprint): Use fputs.
8691 * doc/m4.texinfo (Invoking m4) <--error-output>: errprint and

8694 --error-output.
8695 * doc/Makefile.am: Add `TAGS' support.
8696 (MAINTAINERCLEANFILES): Remove texinfo.tex and mdate-sh which are
8697 in `config/' now.
8698 * config/Makefile.am (MAINTAINERCLEANFILES): New.
8700 2001-08-17 Akim Demaille <akim@epita.fr>

8717 2001-08-16 Gary V. Vaughan <gary@gnu.org>
8719 m4_modules are no more, we use lt_dlhandles directly and let
8720 latest libltdl features manage the list of loaded modules.
8721 * acinclude.m4: Regenerated.
8722 * m4/ltdl.c: Updated from master copy.
8723 * m4/module.c: Reimplemented to take advantage of advances in
8724 libltdl.
8725 * m4/builtin.c (m4_builtin_find_by_name): Traverse loaded module
8726 list with lt_dlhandle_next.
8727 (m4_builtin_find_by_func): Ditto.
8728 (m4_builtin_table_install): Use lt_dlhandle.
8729 (m4_macro_define): Ditto.
8730 (m4_macro_table_install): Ditto.
8731 m4/module.h: Prototype new module management API.
8732 (m4_modules): No longer required.
8733 (m4_module_init_t, m4_module_finish_t): POSIX namespace
8734 violations, renamed to...
8735 (m4_module_init_func, m4_module_finish_func): ...these,
8736 respectively.
8737 (M4INIT_HANDLER): Clean way to declare init functions in modules.
8738 (M4FINISH_HANDLER): And similarly for finish functions.
8739 * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER
8740 -- Add indirection to the CONC macro so that arguments are
8741 correctly expanded.
8742 * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
8743 * modules/shadow.c (m4_init_module): Ditto.
8744 Due to new init function semantics, be careful to perform the
8745 initialisation only on first load.
8746 * modules/perl.c (m4_init_module): Ditto. And Ditto.
8747 (m4_finish_module): Replaced with M4FINISH_HANDLER.
8748 Due to new finish function semantics, be careful to perform the
8749 finalisation only on first load.
8750 * m4/m4private.h (m4_module): Removed in favour of...
8751 (m4_module_data): ...structure without all the wrapper fields.
8752 Instances of this new structure are stored associated lt_dlhandles
8753 with lt_dlcaller_data_set().
8754 * m4/builtin.c (m4_builtin_define): Takes a handle argument
8755 instead of the old module argument.
8756 (m4_builtin_table_install): Ditto.
8757 * modules/load.c (m4_resident_module): Removed. This is no
8758 longer implemented as a magic symbol...
8759 * modules/m4.c (m4_resident_module): Ditto.
8760 * modules/load.c (M4INIT_HANDLER): ...the module init function now
8761 uses the ltdl api to make the module resident.
8762 * modules/m4.c (M4INIT_HANDLER): Ditto.
8763 * modules/load.c (builtin_modules): Traverse the loaded module
8764 list with lt_dlhandle_next.
8765 (builtin_load): Much simplified in light of the reimplemented
8766 module loader.
8767 * src/freeze.c (produce_module_dump): Cleaned up and optimised in
8768 light of the m4/module.c rewrite.
8769 (produce_symbol_dump): Ditto.
8770 (reload_frozen_state): Ditto.
8771 * m4/list.c, m4/list.h: Files deleted. No longer required.

8773 (libm4_la_SOURCES): Delete list.c reference.
8774 * m4/m4private.h (m4_token_data): Add a handle field. This
8775 eliminates many of the searches to find the handle associated with
8776 various tokens that are passed between functions.
8777 (struct m4_symbol): Removed the module field. The
8778 module association does not belong with the symbol...
8779 * m4/input.c (struct m4_builtin): ...it belongs with the builtin
8780 that the module implementation code is from. Added a handle
8781 field.
8782 (m4_push_macro): Add a `handle' argument. Changed all callers.
8783 (init_macro_token): Set the `handle' field for the
8784 m4_token_data.
8785 * m4/macro.c (expand_argument): Copy the new handle field during
8786 reassignment.
8787 * modules/m4.c (macro_install): Use the new handle field to
8788 optimise the search for the correct builtin structure, and pass
8789 the handle details to m4_builtin_define.
8791 2001-08-15 Akim Demaille <akim@epita.fr>
8793 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Be sure `m4/' exists
8794 when creating `m4/obstack.h'.
8795 * tests/Makefile.am (TESTS_ENVIRONMENT): Pass top_srcdir and
8796 top_builddir.
8797 * tests/defs: Make them absolute.
8798 (CDPATH) Neutralize.
8799 * tests/gethem: Use them.
8801 2001-08-14 Gary V. Vaughan <gary@gnu.org>
8803 * config/ltmain.sh: Doh! Import again for a quoting fix that
8804 prevented any regression test from passing.
8806 * m4/m4module.h (obstack.h): Choose between installed version
8807 and shipped version based on configure tests.
8808 * src/freeze.c (obstack.h): Ditto.
8810 * acconfig.h: Removed. No longer required.
8812 * bootstrap: Rewritten to play nicely with Autoconf 2.5x.
8813 * configure.in (MY_NAME, MY_VERSION): Define these once, and feed
8814 them to AC_INIT and AM_INIT_AUTOMAKE.
8815 * Makefile.am (AUTOMAKE_OPTIONS): Remove `gnits' which would
8816 disallow MY_NAME and MY_VERSION arguments to AM_INIT_AUTOMAKE.
8817 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Don't choke on
8818 shell variable m4_cv_func_obstack_h.
8819 * tests/defs (M4): Be more careful about relative path to libtool
8820 script and m4 binary by using $srcdir.
8822 * src/main.c (main): Use lt_dlinsertsearchdir to prepend -M
8823 optargs to the existing libltdl search path.
8824 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.
8825 * m4/ltdl.c: Updated.
8826 * m4/ltdl.h: Ditto.
8827 * config/ltmain.sh: Ditto.
8829 2001-08-11 Gary V. Vaughan <gary@gnu.org>
8831 * src/main.c (main): Add `-b' (for `batch') mode switch to force

8863 * doc/m4.texinfo (Include): Add missing blank.
8864 * m4/Makefile.am (EXTRA_DIST): Distribute gnu-obstack.h and

8889 2001-04-08 Roderick Koehle <Roderick.Koehle@infineon.com>
8891 * modules/format.c (format): Formatting for %f was not
8892 interpreting the position of the decimal point correctly for
8893 whole numbers.
8895 2000-12-01 Gary V. Vaughan <gary@gnu.org>
8897 * TODO: Removed m4exit bug.
8898 * modules/load.c (m4_resident_module): Make this module resident.
8899 * module/m4.c (m4_resident_module): Ditto.
8900 * m4/modules.c (m4_module_load): Use new ltdl resident modules
8901 feature to mark modules as resident if they export
8902 `m4_resident_module' as TRUE.
8903 (m4_module_unload): Do not remove resident modules, and take care
8904 with symbol insertion and deletion with resident modules.
8905 * m4/ltdl.c, m4/ltdl.h: Update to latest unreleased versions to
8906 use resident modules feature.
8908 2000-11-30 Gary V. Vaughan <gary@gnu.org>

8911 or implemented. Added some more entries.
8912 * NEWS: Updated.
8913 * README: Updated.
8914 * modules/README: Updated.
8915 * doc/m4.texinfo: Updated.
8917 * modules/gnu.c (builtin_functions): Make indir orthogonal to
8918 builtin, in that each is recognised as a macro only with parameters
8919 (builtin_indir): Passing 0 arguments is now an error, as with
8920 builtin.
8922 * src/main.c (usage): Added missing description of `-c' option.
8924 2000-11-29 Gary V. Vaughan <gary@gnu.org>
8926 Consolidate the myriad of dispersed test scripts into the
8927 tests subdirectory. I think I now have all the file where I
8928 want them, so there shouldn't be anymore upheaval =)O|
8929 Honest!
8930 * tests/Makefile.am: Updated to run the new tests added below.

8949 * examples/Makefile.am, modules/Makefile.am: Updated to

8967 modules/unfrozen.m4, modules/unload.test: Removed.
8969 Move the implementation of GMP support for the mpeval() builtin
8970 into a loadable module that depends on libgmp. mpeval() and
8971 eval() share a common parser, now in m4/evalparser.c; the code
8972 in m4/numb.c and m4/numb.h is now physically split between
8973 m4/eval.c (the eval() backend) and modules/mpeval.c (the
8974 mpeval() backend), rather than being differentiated by cpp
8975 macros and multiple inclusion. The mpeval module is always
8976 built but will generate an diagnostic if it is used from an
8977 installation that didn't link in the gmp library.
8978 * modules/Makefile.am: build and install the new mpeval module.
8979 * modules/mpeval.c: Now contains the former parts of m4/numb.c
8980 and m4/numb.h that are required for gmp support in mpeval().
8981 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
8982 * m4/evalmp.c: Removed.
8983 * m4/m4module.h: Removed conditional prototype for
8984 m4_mp_evaluate().
8985 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
8986 and m4/numb.h that do not rely on gmp.
8987 * m4/evalparse.c: New file, contains the shared parts of the
8988 eval() and evalmp() parser implementations, and is no longer
8989 unencumbered by cpp magic to uncover the right parts.
8990 * m4/numb.h: Removed. It's former contents are split between
8991 m4/eval.c and modules/mpeval.c.
8992 * m4/numb.c: ditto.
8994 * tests/other-tests/changeword.test: New test. Rudimentary
8995 testing of changeword builtin runs only if --wnable-changeword
8996 was used at configure time.
8997 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
8998 alternation correctly. Split into two expressions to compensate.
8999 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
9000 * modules/Makefile.am: Build changeword module.
9001 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
9002 only when --enable-changeword was passed to configure.
9003 (builtin_changeword): If --enable-changeword was not used, then
9004 report that changeword() builtin has no support in m4 binary.
9006 2000-11-28 Gary V. Vaughan <gary@gnu.org>
9008 * src/main.c (main): Fixed a particularly nasty bug is
9009 user_search_path setting -- the -M flag processing must be
9010 extremely careful with search path ordering, or else the default
9011 installed module directory (possibly containing modules from a
9012 previous release) is placed earlier in the search path than any -M
9013 arguments (which are relied upon to load uninstalled modules with
9014 most of the tests in the regresion suite).
9016 * modules/load.c (builtin_load): Nasty hack to prevent adding
9017 symbols to symtab again if a module is loaded more than once.
9018 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
9020 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
9021 possible NULL pointer dereference.
9023 * m4/module.c (m4_module_find_by_modname): Renamed from
9024 m4_module_modname_find. Fixed all references.
9025 (m4_module_find_by_builtin): New function.
9027 * modules/modfreeze.test: load the `load' module with each
9028 invocation.
9029 * src/freeze.c (produce_frozen_state): Simplified in light of
9030 module field in m4_symbol. Allow a third argument for text macros
9031 to name the originating module.
9032 (reload_frozen_state): ditto.
9033 * m4/m4module.h: Fixup prototypes.
9034 * m4/builtin.h (m4_builtin_define): Add a module argument so
9035 that symbols can be registered against the defining module.
9036 (m4_macro_define): ditto.
9037 * m4/m4private.h (m4_symbol): Make the module field const to save
9038 on casting in the rest of the code.
9039 (SYMBOL_MODULE): New macro.
9041 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
9042 symbol reference maintenance bugs when removing a symbol from the
9043 symtab.
9045 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
9047 2000-11-27 Gary V. Vaughan <gary@gnu.org>
9049 * configure.in (m4_cv_func_obstack): A better check for whether
9050 libc has an obstack implementation.
9051 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
9053 * configure.in (--with-modules): Changed semantics. This
9054 option is now used to list modules to be preopened.
9055 * src/m4.h: #include "ltdl.h" unconditionally.
9056 * src/main.c: Removed all dependencies on WITH_MODULES.
9057 * src/freeze.c: ditto.
9058 * modules/Makefile.am: ditto.
9059 * m4/m4.c (builtin_m4exit): ditto.
9060 * modules/modpath1.test: ditto.
9061 * modules/modpath2.test: ditto.
9062 * modules/modpath3.test: ditto.
9063 * modules/modpath4.test: ditto.
9064 * modules/modtest.test: ditto.
9065 * modules/shadow.test: ditto.
9066 * modules/unload.test: ditto.
9068 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
9069 comes up on demand in LTLIBOBJS now.
9070 * configure.in (getopt_long): Creating and relying on a link for
9071 getopt.h on hosts with no getopt_long() of thier own works
9072 correctly now. This is necessary so that callers of getopt_long()
9073 can simply `#include <getopt.h>': the naive way of doing this
9074 would end up using our own getopt.h and the installed
9075 getopt_long(), which is asking for trouble!
9076 (obstack_init): A similar argument applies to obstack.h and
9077 obstack_init().
9079 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
9080 On Solaris-2.5 (at least) the native dlopen implementation
9081 gets confused about m4.o when looking for module "m4". This
9082 version always looks for .la an .$lib_ext suffixed names first
9083 to work around the problem. Sigh.
9085 * po/POTFILES.in: Take account of these file movements.
9086 * src/Makefile.am (m4_SOURCES): removed eval.c.
9087 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
9088 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
9089 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
9090 * modules/m4.c (builtin_eval): Use m4_evaluate().
9091 * m4/eval.c: Moved here from src/eval.c to facilitate
9092 implementation of eval() builtin as part of the `m4' loadable
9093 module.
9094 (m4_evaluate): renamed from evaluate for namespace cleanliness.
9095 * m4/numb.c: Moved here from src/numb.c, since it is #included
9096 into eval.c at compile time.
9097 * m4/m4module.h (m4_evaluate): Added prototype.
9098 * src/m4.h (evaluate): Removed prototype.
9100 2000-11-25 Gary V. Vaughan <gary@gnu.org>
9102 * modules/perl.c (builtin_perleval): Use PL_na for
9103 compatibility with perl-5.6.
9105 * src/main.c (main): It is now safe to
9106 ``m4_module_install("m4")'', without tripping over the m4
9107 binary itself!
9108 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
9109 versions having fixed the insidious module search order bug.
9111 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
9112 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
9114 * configure.in: Figure out whether to use the installed
9115 getopt.h or the supplied one.
9116 * src/Makefile.am: ditto.
9118 * po/POTFILES.in: List files in their new positions.
9120 * config/ltmain.sh: This needs to be checked in to match the
9121 libtool macros copied to acinclude.m4 (until a released
9122 libtool copes with m4's needs).
9123 * bootstrap: Run gettextize.
9125 2000-11-24 Gary V. Vaughan <gary@gnu.org>
9127 * AUTHORS: Added my details.
9128 * TODO: updated.
9129 * NEWS: updated.

9165 normally -- i.e. without the -G option.
9166 * modules/gnu.c: New file implementing a new loadable module wuth
9167 definitions for all the gnu extension builtins.
9168 * modules/format.c: Moved here from src/format.c. Now included
9169 directly by gnu.c.
9171 * src/main.c (main): Load the traditional module if m4 was
9172 started in `no_gnu_extensions' mode.
9173 * modules/traditional.c: New file implementing the ``unix'' macro,
9174 required when m4 is executed in traditional mode, as a loadable
9175 module.
9177 * src/main.c: Renamed from m4.c to avoid confusion with
9178 modules/m4.c.

9184 * m4/m4module.h: Prototypes for exported functions and types moved
9185 to this directory from the src directory.
9186 * m4/m4private.h: Moved here from src/m4private.h to facilitate
9187 the migration of all builtin implementations to loadable modules.
9188 * m4/macro.c: Moved this file here from the src directory,
9189 renaming all exported symbols to use the prefix ``m4_''.
9190 * m4/builtin.c: ditto.
9191 * m4/module.c: ditto.
9192 * m4/symtab.c: ditto.
9193 * m4/debug.c: ditto.

9197 * m4/ltdl.h, m4/ltdl.c: ditto.
9198 * m4/utility.c: Odd functions moved here from files in the src
9199 directory to facilitate builtin migration.
9201 2000-08-12 Gary V. Vaughan <gary@gnu.org>
9203 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
9204 error message, to make translators' jobs a little easier.
9205 (builtin_builtin): ditto.
9206 (builtin_traceon): ditto.
9207 (builtin_traceoff): ditto.

9230 (AC_OUTPUT): touch stamp-h.in, not stamp-h.
9232 * doc/m4.texinfo: Fixed to work with --html option of makeinfo.
9233 Removed `Prev', `Next' and `Up' fields of all @nodes now that
9234 makeinfo calculates them for us, and to make any future
9235 reorganisation easier.
9236 (Frozen files): Document format version 2.
9237 `V' now takes argument `2'.
9238 `F' can take a single argument if symbol and builtin names
9239 are the same, or 3 arguments if the builtin is from a module.
9240 New `S' specification for saving syntax table contents.
9241 New `M' specification for saving loaded module names.
9242 * src/freeze.c: Implement them.
9243 * src/input.c (syntax_code): For interpreting frozen syntax
9244 state.
9246 * examples/Makefile.am: Add the contents of the WWW directory to
9247 the distribution.
9248 * examples/WWW/Makefile: ditto,

9250 whether a change has occured.
9251 * examples/WWW/_header.htm: Bumped version number.
9252 * examples/WWW: Regenerated content.
9254 * m4/Makefile.am (AUTOMAKE_OPTIONS): Support for non-ANSI
9255 compilers comes much easier without ansi2knr.
9256 * src/Makefile.am (AUTOMAKE_OPTIONS): ditto.
9258 * m4/list.c: New generic list container type.
9259 * m4/list.h: Interface to new container type.

9382 * src/builtin.c: Much improved macro definition style.
9383 * src/m4private.h: Internal structures for m4_builtin and
9384 m4_macro instances. These are not exposed to module writers.

9452 increment serial number.
9454 * Makefile.am (SUBDIRS): Moved @MODULES_DIR@ to compile before
9455 src dir and immediately after libm4 is built for confidence that
9456 it doesn't rely on the src directory.
9457 (SUBDIRS): Moved doc dir to the end since helptoman.pl and
9458 makeinfo stop the build on cygwin (because they don't work).
9460 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
9462 * m4/m4private.h: ...is not a public header, so moved to src.
9463 Add `#include <config.h>', `#define _COMPILING_M4' and
9464 `#include "m4.h".
9465 * m4/Makefile.am (noinst_HEADERS): remove m4private.h.
9466 * src/Makefile.am (noinst_HEADERS): add m4private.h.

9489 m4/libm4.la.
9490 * m4/m4error.h: Renamed error.h, for installation to

9506 From Akim Demaille <akim@epita.fr>
9508 2000-01-17 Gary V. Vaughan <gary@gnu.org>
9510 * src/ltdl.c: Use access() to abort doomed module load attempts
9511 if module file does not exist.
9513 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
9514 getopt1.o will already be used if appropriate, so I moved getopt.c
9515 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
9517 * modules/modpath1.test: Use correct filename in header line.
9518 * modules/modpath2.test: ditto.
9519 * modules/modpath3.test: ditto.
9520 * modules/modpath4.test: ditto.
9522 Without these changes lt_dlopen("test") attempts to
9523 LoadLibrary("/bin/test") on Windows, which although harmless
9524 generates a spurious error message which spoils most of the tests:
9525 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
9526 (TESTS): s/test.test /modtest.test /
9527 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /

9530 * modules/modpath2.test: ditto.
9531 * modules/modpath4.test: ditto.
9532 * modules/modpath3.test: s/-m test /-m modtest /
9533 * modules/shadow.m4: use {un,}loadmodule(`modtest').
9535 2000-01-16 Gary V. Vaughan <gary@gnu.org>
9537 * src/ltdl.c (find_file): Updated to new version with fixed memory
9538 allocation bug in `next'.

9541 * modules/Makefile.am: Cleaned up and reordered.
9543 2000-01-16 René Seindal <rene@seindal.dk>
9545 * modules/Makefile.am (TESTS): New tests for the module system.
9547 * modules/*.test: New files.

9550 Treats -M and -m as the arguments -D -U and -t, ie deferred.
9552 * src/m4.h: Added declaration of module_init().
9554 * src/module.c (module_init): No longer static
9556 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
9557 Added to shut up automake about non standard libtool library
9558 names.
9560 * src/module.c: Disabled DEBUG by default.
9562 * modules/README: Changed example from unload.m4 to shadow.m4
9564 * modules/shadow.m4: Renamed from unload.m4
9566 * modules/Makefile.am (EXTRA_DIST): Removed unload.m4.
9568 * src/m4.c (main): Functionality for -m and -M were reversed.
9569 Fixed.
9571 2000-01-12 Gary V. Vaughan <gary@gnu.org>
9573 * doc/help2man.pl: updated to version 1.020.
9575 * lib/COPYING.LIB: updated to version 2.1.
9577 * lib/m4module.h: restructure the M4_SCOPE code to work when
9578 creating a dll which links with libm4.la and both DLL_EXPORT
9579 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
9580 both defined.
9582 2000-01-11 Gary V. Vaughan <gary@gnu.org>
9584 Merged the following changes from my tree:
9586 1999-06-15 Gary V. Vaughan <gary@gnu.org>
9588 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
9589 ported to compile shared libs.
9591 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
9592 use `__declspec(dllimport)' when linking libm4.la on win32.
9593 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
9595 * configure.in (M4OBJS): Discover whether we need the shipped
9596 implementation of getopt_long.
9597 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
9598 main binary here, as opposed to the module library in lib/libm4.la.
9600 1999-06-14 Gary V. Vaughan <gary@gnu.org>
9602 * modules/README: Updated to describe the improved libltdl based
9603 module scheme.
9604 * README (cygwin): Added some compilation notes for building m4
9605 correctly under cygwin.
9606 * TODO: Cleaned out the entries for the module system since they
9607 are now implemented.
9609 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
9610 all instances of __P with M4_PARAMS.
9612 * lib/getdate.h: removed unreferenced file.
9614 * lib/m4private.h: New file to define the private interface to the
9615 token_data struct, which must be shared between m4module.c, and
9616 builtin.c but not exported to modules built from the installed
9617 m4module.h since it's size changes depending on compile time
9618 options.
9620 * src/m4.h: Lots of stuff moved to lib/m4module.h.
9622 * lib/m4module.h: New file to define the interface available when
9623 compiling m4 modules.
9624 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
9625 necessary for module compilation into this new file.
9627 * lib/Makefile.am (include_HEADERS): install headers (renamed to
9628 avoid nameclash with other system headers) necessary for compiling
9629 modules.
9630 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
9631 so that modules can include the (renamed) installed headers and
9632 be guaranteed a matching implementation.
9633 * lib/m4error.h: renamed from error.h.
9634 * lib/m4obstack.h: renamed from obstack.h.
9635 * lib/m4regex.h: renamed from regex.h.
9636 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
9637 implementation, simply include the shipped version
9638 unconditionally, otherwise it is hard for a module to know
9639 whether the m4obstack.h header it is using matches the
9640 implementation it ends up linking against.
9641 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
9642 the same reason.
9644 1999-05-18 Gary V. Vaughan <gary@gnu.org>
9646 * examples/misc.test: Don't run this test on machines which don't
9647 have a root user in /etc/passwd (e.g. cygwin).
9649 * tests/get-them (/^@example$/): Error messages might have a
9650 ``.exe'' suffix to the program name, or else use the libtool
9651 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
9652 of these cases are now catered for when comparing error messages
9653 in generated tests.
9654 * tests/other-tests/*.test: ditto.
9655 * examples/*.test: ditto.
9657 * tests/defs (M4): use libtool execute mode.
9658 * examples/defs (M4): ditto.
9660 * tests/get-them (END): explicitly close any open file.
9661 (printthem): In a regular expression, '{' is the start of a repeat
9662 count! Use `[{]' for a literal open brace.
9663 (/^@node /): Don't use substr on a string shorter than the trim
9664 length.
9666 1999-05-17 Gary V. Vaughan <gary@gnu.org>
9668 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
9669 substituted.
9670 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
9672 2000-01-10 Andreas Schwab <schwab@suse.de>
9674 * tests/other-tests/gmp.test: Find config.sh in build directory.
9676 * configure.in: Find tests/mkconfig.sh in $srcdir.
9678 * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in
9679 <signal.h> (for SUS2 compliant systems).
9681 * src/stackovf.c: Check for HAVE_SIGINFO_T in addition to
9682 HAVE_SIGINFO_H.
9684 2000-01-10 René Seindal <rene@seindal.dk>

9688 * TODO, NEWS: Cleaned up and updated.
9690 * src/m4.c (main): New variable exit_status for exit status in
9691 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
9692 file cannot be read instead of EXIT_SUCCESS.
9694 * src/builtin.c (m4_indir): Changed error message to help
9695 translators (from Akim Demaille <demaille@inf.enst.fr>).
9697 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
9698 Cygnus.
9700 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
9701 from glic 2.1.2.
9703 * src/input.c (match_input): Reordering of code, to avoid multiple
9704 calls to push_string_init() from obstack_grow(), which can happen
9705 with some compilers (found and fixed by James Bonfield
9706 <jkb@mrc-lmb.cam.ac.uk>).
9708 * src/stackovf.c: Added prototypes for ultrix.
9709 (setup_stackovf_trap): Added __P to cast.
9710 (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>)
9712 2000-01-09 René Seindal <rene@seindal.dk>
9714 * doc/m4.texinfo (Changequote): Added comment about changing
9715 quotes when the old quote is a part of the new.
9717 * src/builtin.c (expand_ranges): Added break after trailing dash.
9718 This caused misbehavious on some systems (found and fixed by Akim
9719 Demaille <demaille@inf.enst.fr>).
9721 * AUTHORS: Thomas Tanner included
9723 * acconfig.h: Added entry for ss_sp (see below).
9725 * configure.in (use_stackovf): Added check for stack_t with member
9726 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert
9727 <eggert@twinsun.com>).
9729 * doc/m4.texinfo (Frozen files): Added a simpler example for
9730 generating frozen files from several input files.
9732 1999-11-14 Paul Eggert <eggert@twinsun.com>

9739 * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal.
9741 * src/module.c: reindented.
9742 (module_load): return if this is a repeated load of same module.
9743 (module_init): slight change of logic to avoid repeated
9744 initialisation debug messages.

9747 in the distribution.
9749 * modules/Makefile.am (test_la_LDFLAGS): set to -module to silence
9750 automake warnings about missing lib prefix.

9759 1999-11-09 Paul Eggert <eggert@twinsun.com>
9761 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
9762 and zero, as Solaris 7 cc does.
9763 (bcopy): Remove macro; no longer needed with new obstack.h.
9765 * src/output.c (freeze_diversions): Don't assume that a
9766 diversion size can fit in `int'. Check for diversion file
9767 size too large to be printed with `unsigned long'.
9769 * src/Makefile.am (CFLAGS): Omit -Wall.
9771 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.

9802 are modules, not linktime libraries.
9803 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
9804 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
9805 avoidance on exported symbols.

9812 * src/m4.c (--load-module): dynamically load named runtime module
9813 into running executable before reading the source.
9814 (--module-directory): prepend a directory to the module search
9815 path.
9816 (module_init()): Do this the first time we load a module instead;
9817 if the module subsystem is broken normal m4 scripts can still run.
9818 * src/m4.h (install_builtin_table): is now exported.
9820 1999-03-26 Gary V. Vaughan <gary@gnu.org>
9822 * src/module.c: removed. No longer required.
9823 * po/POTFILES.in: removed src/module.c.
9825 * Makefile.am (MAINTAINERCLEANFILES): Remove all the files that
9826 the bootstrap script can recreate.
9827 * acm4/Makefile.am (MAINTAINERCLEANFILES): ditto.
9828 * doc/Makefile.am (MAINTAINERCLEANFILES): ditto.
9829 * examples/Makefile.am (MAINTAINERCLEANFILES): ditto.

9832 * modules/Makefile.am (MAINTAINERCLEANFILES): ditto.
9833 * src/Makefile.am (MAINTAINERCLEANFILES): ditto.
9834 * tests/Makefile.am (MAINTAINERCLEANFILES): ditto.
9836 * acinclude.m4: removed. `aclocal -I acm4' handles this much
9837 better.
9838 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
9839 * acm4/gettext.m4: removed. It causes a multiple definition vs.
9840 the installed gettext.m4 file when running aclocal.
9842 1999-03-25 Gary V. Vaughan <gary@gnu.org>
9844 * configure.in (AM_INIT_AUTOMAKE): bumped version number to
9845 distinguish this from the last prerelease.
9846 (AC_LIBLTDL_CONVENIENCE): build libltdl as a convenience library
9847 in its own subdirectory.
9849 * modules/Makefile.am (*_SOURCES): renamed to use libtool's "no
9850 lib prefix on a module" feature.
9851 (LDFLAGS): Added `-module -avoid-version' flags to build
9852 versionless module libraries.
9853 * src/builtin.c (m4_load_module): use libltdl.
9854 (module_unload_all): use libltdl.
9855 * src/m4.c (module_init): initialise module loading on demand for
9856 better diagnostics, and so that m4 will still work even if
9857 the module code is broken.
9858 * src/m4.h (module_init): removed. No longer relevant.
9859 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on
9860 exported symbols for compatibility with dlpreopening.
9861 * modules/test.c (m4_macro_table, m4_init_module,
9862 m4_finish_module): ditto.
9863 * modules/time.c (m4_macro_table): ditto.
9865 * bootstrap: New file. Runs all the autoutils in the right order
9866 after a fresh checkout, or a make maintainer-clean.
9868 1999-02-18 Akim Demaille <demaille@inf.enst.fr>
9870 * src/builtin.c (dump_symbols): New function, factoring common
9871 content of m4_dumpdef and m4_symbols.
9872 (m4_dumpdef): Use it.
9873 (m4_symbols): New function, implementing `symbols'. Use it.
9874 * doc/m4.texinfo: Fixed missing commas after @xref, so that the
9875 file compile with modern makeinfo.
9876 (Symbols): New node, documenting symbols.
9877 (direntry): Modernize.
9879 1998-12-11 René Seindal <rene@seindal.dk>
9881 * src/builtin.c (predefined_tab): New predefined macros
9882 __m4_changeword__, __m4_gmp__ and __m4_modules__ for testing for
9883 configure time options.
9885 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
9887 * src/module.c (module_try_load): Don't try to be clever and
9888 overwrite argument string. Instead allocate all constructed
9889 strings locally, since they can have arbitrary lengths. Make
9890 arguments pointers to const.
9891 (module_search): Simplify due to above change.
9893 1998-11-29 René Seindal <rene@seindal.dk>
9895 * Prerelease 1.4n.
9897 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): New tests.
9899 * tests/other-tests/import-environment.{m4,test}: New test.

9906 New global variable discard_comments.
9908 * src/m4.h (token_type): New TOKEN_NONE for tokens to be
9909 discarded, ie never returned from next_token().
9910 Added declaration of discard_comments.
9912 * src/input.c (next_token): Now loops until token type is not
9913 TOKEN_NONE. Comments are now given this type when comments should
9914 be discarded.
9916 * doc/m4.texinfo (Invoking m4): Updated for --import-environment
9917 and mpeval.
9919 1998-11-28 René Seindal <rene@seindal.dk>
9921 * src/m4.c (main): New option --import-environment (no single
9922 letter option).
9924 * When configured with --with-gmp both the normal (fast) eval()
9925 and the gmp aware mpeval() are defined. To restore previous
9926 bahaviour use "define(`eval', defn(`mpeval'))".
9928 * tests/other-tests/gmp.m4: Changed to use mpeval().
9930 * src/evalmp.c: New file for compiling eval.c as gmp aware.
9931 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
9933 * src/eval.c: Now includes "numb.c" directly. Everything in this
9934 file must by static, except evaluate(), which is changed to
9935 mp_evaluate() if USE_GMP in force.
9937 * src/numb.c: Changed to be included by eval.c instead of being
9938 compiled separately. Everything is declared static.
9940 * src/numb.h: Removed declarations of functions, as numb.c is now
9941 included by eval.c.
9943 * src/builtin.c: Declaration of m4_mpeval() added.
9944 Inserted `mpeval' in builtin table.
9945 (do_eval): New function with common code for m4_eval and m4_mpeval.
9946 (m4_mpeval): New function for gmp version of eval.
9948 * src/m4.h: Declaration of mp_evaluate().
9950 * src/Makefile.am (m4_SOUCES): Includes mpeval.c.
9951 (EXTRA_m4_SOURCES): Now has numb.c and numb.h
9953 * src/m4.c (main): m4 --version also shows which options were used
9954 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
9956 1998-11-27 René Seindal <rene@seindal.dk>
9958 * Error messages now always print program name before input file
9959 name as specified by GNU coding standards. Reported by Akim
9960 Demaille <demaille@inf.enst.fr>.
9962 * doc/m4.texinfo (Include): Change due to changed error message
9963 format.
9964 (Eval): Do.
9966 * tests/get-them: Minor change to sed script due to changed error
9967 message format.
9969 * src/m4.c (print_program_name): New func used to print program
9970 name, input file and line number in error (). Used as an
9971 error_print_progname handler.
9972 (reference_error): Removed.
9973 (main): Assigns error_print_progname.
9975 * src/m4.h (M4ERROR): Removed reference_error ().
9977 1998-11-25 René Seindal <rene@seindal.dk>
9979 * Updated to libtool 1.2b.
9981 * src/builtin.c (install_builtin_table): Added braces to avoid
9982 warning of ambiguous 'else'.
9984 * src/module.c: Inserted search path code from path.c modified to
9985 use new interface.
9986 (module_init): Configured default path used only if M4MODPATH is
9987 not set.
9988 (module_try_load): Now reads libMODULE.la as generated by libtool
9989 for actual module name.
9990 (module_load): Gives better error messages on failure.
9992 * src/m4.h: Added declarations of structures and functions for
9993 generic search path handling.
9995 * src/path.c: Removed all module specific code and introduced new
9996 functions of more generic search path handling.
9998 1998-11-24 René Seindal <rene@seindal.dk>
10000 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
10001 included gettext, as <libintl.h> might not be found
10002 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
10004 1998-11-22 René Seindal <rene@seindal.dk>
10006 * src/output.c (insert_diversion): Fixed bug that might cause m4
10007 to read from standard output! Triggered by input
10008 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
10009 so now 'undivert(0)' does nothing.
10011 1998-11-18 René Seindal <rene@seindal.dk>
10013 * Prerelease 1.4m.
10015 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
10016 could be changed when compiling a illegal regexp, causing later
10017 use of the regexp to dump core.
10019 * src/module.c (module_load): Changed error message to conform to
10020 standards.
10022 * src/m4.c (usage): Added message about reporting bugs.
10024 * doc/m4.texinfo (Changeword): Corrected a wrong example.
10025 (Changeword): Added note about the type of regexps used.
10027 * ltconfig, ltmain.sh: New files from Libtool 1.2.
10029 * configure.in: Added calls to AM_ENABLE_SHARED, AM_DISABLE_STATIC
10030 and AM_PROG_LIBTOOL.
10032 * acm4/modules.m4 (AM_WITH_MODULES): Redone completely to work
10033 with libtool.
10035 * modules/Makefile.am: Changed completely to compile modules using
10036 libtool. The modules are compiled as shared libraries, and are
10037 renamed when installed.
10039 * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
10040 USE_SHL_LOAD to HAVE_SHL_LOAD
10042 * src/builtin.c (shipout_string): Now tests for a NULL string.
10044 * src/module.c: New level of indirection around non-portable
10045 functions to load shared objects. Intended to encapsulate the non
10046 portable parts better and to reduce the number of #ifdefs in the
10047 code.
10049 * Makefile.am (DIST_SUBDIRS): Instead of EXTRA_DIST for added
10050 directory modules/ to the distribution.
10052 1998-11-15 René Seindal <rene@seindal.dk>
10054 * Prerelease 1.4l.
10056 * modules/stdlib.c: New module `stdlib' defining some standard
10057 functions: getcwd, getlogin, getpid, getppid, getuid, getpwnam,
10058 getpwuid, hostname, rand, srand, getenv, setenv, unsetenv, uname.
10060 * src/builtin.c (shipout_string): New convenience function for
10061 builtins and modules.
10063 * src/module.c (module_load): Tentative support for
10064 shl_load/shl_findsym, but I cannot test it. Copied from MetaHTML.
10066 * Makefile.am (SUBDIRS): Directory modules added if configured.
10068 * modules/Makefile.am: Now correctly compiles and installs
10069 modules in pkglibexecdir.
10071 * src/m4.h: WITH_MODULES defined iff HAVE_DLOPEN or USE_SHL_LOAD.
10072 These two are now initialised by autoconf macros.
10074 * src/path.c (module_env_init): MODULE_PATH is always on the
10075 search path.
10077 * src/Makefile.am: Now generated pathconf.h which defined the
10078 default MODULE_PATH.
10080 * configure.in (pkglibexecdir): Added defintion of pkglibexecdir,
10081 where modules are installed.
10083 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
10084 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
10085 build and install automatically, and it is prepared for other
10086 interfacec than dlopen().
10088 * src/builtin.c (predefined_tab): Added __m4_version__ for the
10089 current version of GNU m4. It is a GNU extension.
10091 1998-11-14 René Seindal <rene@seindal.dk>
10093 * tests/Makefile.am (GENERATED_TESTS): Added new
10094 generated-tests/changesy.8.test
10096 * doc/m4.texinfo (Changesyntax): Documentation for escape
10097 syntax class.
10099 * src/macro.c (expand_token): Check for escaped macro call before
10100 symbol table lookup.
10102 * src/builtin.c (m4_changesyntax): Added `@' flag to define escape
10103 characters
10105 * src/input.c: New static variable use_macro_escape, which is TRUE
10106 iff some character has code SYNTAX_ESCAPE
10107 (input_init): Added initialisation of use_macro_escape.
10108 (check_use_macro_escape): New function to synchronise
10109 use_macro_escape with the syntax table.
10110 (set_quotes): Added call to check_use_macro_escape()
10111 (set_comment): Do.
10112 (set_syntax): Do.
10113 (next_token): Added new case for IS_ESCAPE.
10115 * src/m4.h (SYNTAX_ESCAPE): Defined as simple syntax category.
10117 1998-10-13 René Seindal <rene@seindal.dk>
10119 * Prerelease 1.4k.
10121 * tests/Makefile.am (GENERATED_TESTS): Renamed gentest to
10122 generated-tests.
10124 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): Added manually
10125 maintained tests in tests/other-tests. These currently tests for
10126 8-bit transparency, multiple precision arithmetic and sync-line
10127 output. Test for stackoverflow detection does not work.
10129 * examples/Makefile.am (TESTS): Added tests for all example files.
10131 * examples/mktests.sh: New file. Help program for creating test
10132 files.
10134 * tests/mkconfig.sh: New file to generate tests/config.m4 and
10135 tests/config.sh. This is for tests of configure selectable
10136 features. Picks up all set WITH_ and ENABLE_ veriables from
10137 config.h
10139 * src/path.c (path_search): Added argument 'char **expanded_name'
10140 to return the expanded name.
10142 * src/m4.h: Added 2nd argument to declaration of path_search().
10144 * src/m4.c (main): Added 2nd argument to path_search().
10146 * src/freeze.c (reload_frozen_state): Do.
10148 * src/builtin.c (m4_undivert): Do.
10149 (include): Do.
10151 1998-10-11 René Seindal <rene@seindal.dk>
10153 * acm4/Makefile.am (ACINCLUDES_M4): Added gmp.m4 and modules.m4
10155 * acm4/modules.m4: New file. Defines AM_WITH_MODULES.
10157 * acm4/gmp.m4: New file. Defines AM_WITH_GMP.
10159 * configure.in: Introduced AM_WITH_MODULES and AM_WITH_GMP.
10161 * AUTHORS, ChangeLog: Changed all dates to ISO 8601.
10163 * intl/: Updated to GNU gettext 0.10.35.
10165 * doc/m4.texinfo (Format): Documented that format is blind.
10167 * src/builtin.c (builtin_tab): Builtin format marked as blind.
10169 1998-10-07 René Seindal <rene@seindal.dk>
10171 * Prerelease 1.4j.
10173 * tests/Makefile.am (GENERATED_TESTS): Changed .m4 extension to
10174 .test, as the files are no longer just m4 input.
10176 * tests/get-them (FILE): Changed .m4 extension to .test.
10178 * src/m4.h (token_type): New token type TOKEN_SPACE introduced.
10179 Otherwise quoted strings with leading whitespace first in a macro
10180 argument would be eliminated.
10182 * src/macro.c (expand_token): Handles new token type TOKEN_SPACE.
10183 (expand_argument): Do.
10185 * src/input.c (next_token): SPACE and NUM/OTHER characters are only
10186 grouped together iff both quote and comment strings are single
10187 character. Otherwise they might include a comment/quote leader.
10188 (next_token): Returns new token type TOKEN_SPACE.
10190 * src/builtin.c (push_builtin_table): New function to push a
10191 builtin_table on the stack without installing its contents.
10192 (find_builtin_by_name): Added call to push_builtin_table() if
10193 reading frozen files. Otherwise the builtins named in the frozen
10194 files could not be found.
10195 (install_builtin_table): Changed to use push_builtin_table()
10197 1998-10-04 René Seindal <rene@seindal.dk>
10199 * po/pl.po: Polish translation added.
10201 * po/POTFILES.in: src/module.c added.
10203 1998-10-04 René Seindal <rene@seindal.dk>
10205 * Prerelease 1.4i.
10207 * configure.in (ALL_LINGUAS): Added Polish pl.po
10209 1998-10-03 René Seindal <rene@seindal.dk>
10211 * Many files: Incorporated changes to implement dynamic modules.
10212 Detailed comments in src/modules.c and modules/README
10214 * src/module.c: New file, implements the OS dependant parts of
10215 dynamic module loading.
10217 * src/Makefile.am (m4_SOURCES): Added module.c
10219 * src/builtin.h: New file, declares some functions from builtin.c
10220 that are of use for other modules (shipout_int, numeric_arg,
10221 skip_space, bad_argc), and the macros ARG() and DECLARE().
10223 * src/builtin.c (install_builtin_table): New function. Each
10224 module brings in a builtin_table, which is pushed on a stack.
10225 (struct builtin_table): New struct for list of builtin_tables.
10226 (m4_loadmodule): New function to implement builtin "loadmodule".
10227 (shipout_int): No longer static, to be used by modules.
10228 (numeric_arg): do.
10229 (skip_space): do.
10230 (bad_argc): do.
10231 (builtin_init): changed to call install_builtin_table()
10232 (find_builtin_by_name): Now searches all builtin_tables
10233 (find_builtin_by_addr): do.
10235 * src/path.c: Reorganised to allow for two search paths, one for
10236 include files and one for modules.
10238 * src/m4.h: Added declarations for new functions in module.c and
10239 in path.c.
10241 * src/m4.c (main): Added call to module_init().
10243 * modules: New directory with a few demo modules.
10245 * Makefile.am (EXTRA_DIST): Added modules/* since modules/ is not
10246 in SUBDIRS.
10248 * configure.in: Added modules/Makefile to AC_OUTPUT.
10250 * configure.in: Added code to implement --with-modules. Tests for
10251 <dlfcn.h> and -ldl.
10253 * acconfig.h: Added WITH_MODULES
10255 1998-10-02 René Seindal <rene@seindal.dk>
10257 * examples/Makefile.am (pkgdata_DATA): Removed special target for
10258 check and variables TESTS. These tests are now run from the
10259 tests/ directory.
10261 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
10262 directory. The files stay there but the tests are run from the
10263 tests/ directory.
10265 * tests/Makefile.am (EXTRA_DIST): Added run-test.
10267 * tests/run-test: New file. Run a test manually
10269 * tests/Makefile.am, tests/get_them: Moved automatically generated
10270 tests (from the manual) to sub directory tests/gentest/. The
10271 tests/ directory had gotten a bit messy.
10273 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10275 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\
10276 wrap}.test: Added a few testcases.
10278 1998-08-21 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10280 * Prerelease 1.4h.
10282 * lib/Makefile.am (noinst_HEADERS): regex.h added
10284 * configure.in (jm_WITH_REGEX, jm_PREREQ_ERROR):
10285 acm4/{error,regex}.m4 (from fileutils-3.16u.tar.gz).
10287 * acm4/Makefile.am: created providing rules to create
10288 $(top_srcdir)/acinclude.m4 to be used by aclocal.
10290 * tests/defs (LANGUAGE, LC_ALL, LANG): force them to be
10291 `C'. Reported by Ulrich Drepper.
10293 * Makefile.am (SUBDIRS): Removed checks directory
10294 * configure.in (AC_OUTPUT): Removed checks/Makefile
10296 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
10297 the space when m4.texinfo is edited and whitespace.el is active.
10298 (Defn,example): idem.
10300 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10302 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
10303 ../COPYING. ../Makefile is a file which is certainly present when
10304 test is executed in testSubDir. One can't be sure that the COPYING
10305 file is in .. or ../.. in all situations, the ../Makefile is
10306 always there.
10308 * doc/m4.texinfo (Include): adjusted expected test output
10309 according to new tests, i.e. the input will always come from the
10310 file `in' created by the test.
10312 * tests/Makefile.am: Added three lines at the top to get
10313 esyscmd.1.test working.
10315 * tests/get-them: modified to generate clearer tests who will need
10316 less maintenance when new test examples are created in
10317 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
10318 need the generic file `defs') shell scripts creating `in', `ok',
10319 `out' and when apropriate `okerr' and `err' in the directory
10320 `testSubDir' when executed. The compare of `ok' and `out'
10321 (and of `okerr' and `err') will be the exit status of the test.
10322 `out' must match `ok' (and `okerr' must match `err') for the test
10323 to be succesful.
10325 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
10326 the tests generated by tests/get-them getting it input normally
10327 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
10328 (dot) before the numeric part) is reserved for all other (hand
10329 written) tests. The `+' means one or more times.
10331 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10333 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
10334 supported short man page to refer to info documentation
10335 * helptoman.pl: added
10336 * configure.in: AC_PATH_PROG(PERL,perl)
10337 * Makefile.am (SUBDIRS): doc after src

10840 (set_comment): Free previous comment strings in all cases.
10841 Duplicate even default comment strings.
10843 * configure.in: Updated for Autoconf 2.0.
10844 * Makefile.in (distclean-local): Also delete config.cache.
10846 * m4.c (usage): Reorganize the --help output by topic. Include a
10847 description for debugging flags.
10849 1994-07-29 François Pinard <pinard@iro.umontreal.ca>
10851 * configure.in: If sigaction is available and SA_ONSTACK defined,
10852 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
10853 defined, use sigvec. Else don't compile stackovf.c.
10854 * stackovf.c (setup_stackovf_trap): Idem.
10855 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
10856 and Simon Leinen.
10858 1994-07-21 François Pinard <pinard@iro.umontreal.ca>
10860 * m4.c (usage): Replace printf par fputs.
10861 \f
10862 1994-07-18 François Pinard <pinard@iro.umontreal.ca>
10864 * Release 1.2
10866 1994-07-17 François Pinard <pinard@iro.umontreal.ca>
10868 * configure.in: Check for sigaction and sigvec. Add a new delayed
10869 check for RLIMIT_STACK, combine in the checking for getrlimit.
10870 All those things are not universally available.
10871 * stackovf.c: Split setting up the trap handler and catching
10872 signals, for better taking care of various configure outcomes.
10873 * examples/stackovf.sh: Correct a typo.
10874 Reported by Eric Backus, Jim Avera and Jim Meyering.
10876 1994-07-16 François Pinard <pinard@iro.umontreal.ca>
10878 * ansi2knr.c: New version sent by its author, Peter Deutsch.
10880 1994-07-15 François Pinard <pinard@iro.umontreal.ca>
10882 * Makefile.in: Modify so parallel make will not try making
10883 lib/libm4.a twice simultaneously.
10884 Reported by Jim Meyering.
10886 1994-07-14 François Pinard <pinard@iro.umontreal.ca>
10888 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
10889 error message, for when no code possibility exists. Even if this
10890 line is completely #ifdef'ed out, it brings a syntax error.
10891 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
10893 * Makefile.in (install): Have install depend on all too, for lib
10894 to be remade as needed.
10896 * examples/stackovf.sh: Try ksh, bsh and bash for shells
10897 providing ulimit, instead of using only ksh.
10898 Reported by Jim Avera and Joseph E. Sacco.
10900 1994-07-12 François Pinard <pinard@iro.umontreal.ca>
10902 * Makefile.in (check): Have it depend on all instead of m4. In
10903 this way, a change in lib will be detected and processed.
10905 * builtin.c (numeric_arg): Use strtol and verify the conversion,
10906 instead of using sscanf which stops as soon as there is a
10907 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
10908 and divert(1xyzzy) were all accepted without any warning or error
10909 messages.
10910 * m4.h: Declare strtol as long if not including stdlib.h.
10911 * configure.in: Check for limits.h, and replace strtol if missing.
10912 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
10913 * lib/strtol.c: New file, from elsewhere.
10914 Reported by Andreas Schwab.
10916 1994-07-07 François Pinard <pinard@iro.umontreal.ca>
10918 * macro.c (expand_macro): Cast value to (boolean) prior to
10919 assigning it to traced.
10920 Reported by Tom McConnell.
10922 * Makefile.in (m4): Always make all in lib first.
10923 Reported by Jim Meyering.
10925 1994-07-06 Jim Avera <jima@netcom.com>
10927 * stackovf.c: Isolated OS-dependent sections; Improved portability,
10928 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
10929 handlers), and a default error message if the fault address is not
10930 available (when neither siginfo.h nor BSD sigcontext are supported).
10931 * configure.in: Changes for stackovf.h: Check for sigcontext,
10932 sigaction, sigstack, and define rlim_t as int if necessary.
10933 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
10934 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
10935 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
10937 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
10939 * configure.in: Use AC_SET_MAKE.
10940 * Makefile.in: Use @SET_MAKE@.
10941 Reported by Jim Meyering.
10943 * checks/check-them: Do not trap on SIGQUIT or SIGALRM.
10944 Reported by Ian Taylor.
10946 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
10948 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
10949 because siginfo.h is unrelated to standard headers, and siginfo.h
10950 is already checked for.
10951 Reported by Joseph E. Sacco.
10953 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
10954 PROTOTYPES.
10955 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
10956 AC_PROTOTYPES.
10958 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
10960 * builtin.c (substitute): Use \& to represent this part of the
10961 string which was matched by the whole regexp, instead of
10962 representing the whole string. Any usage of \0 issues a warning
10963 and acts like \&, it will disappear in some subsequent release.
10965 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
10967 * m4.c: Complete prototype for forwarded declaration of usage.
10969 * input.c (init_macro_token): Correct own reference in error
10970 message. Previous name get_macro_func was referred to instead.
10971 (next_char): Correct own reference in error message. Previous
10972 name advance_input was referred to instead.
10974 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
10975 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
10976 and_term, not_term, logical_not_term, cmp_term, shift_term,
10977 add_term, mult_term, exp_term, unary_term, simple_term): Add
10978 prototype to forwarded declarations. Declare parameter v1 as
10979 eval_t * instead of int *. Same for local variable v2 in dyadic
10980 functions. Same for result in exp_term.
10981 * builtin.c (m4_eval): Declare value as eval_t instead of int.
10982 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
10983 unsigned_eval_t instead of unsigned int. Change casts accordingly.
10984 (shipout_int): Cast first argument of ntoa to eval_t.
10985 Reported by Thorsten Ohl.
10987 * macro.c: Complete the prototypes of forwarded expand_macro and
10988 expand_token.
10989 Reported by Thorsten Ohl.
10991 * m4.h: Define voidstar as void * or char * depending on __STDC__.
10992 The Ultrix 3.1 compiler cannot do much with void pointers.
10994 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
10995 * m4.c (xfree): Replace void * by voidstar.
10996 Reported by Tom McConnell.
10998 * ansi2knr.1: New, from elsewhere.
10999 * Makefile.in (DISTFILES): Distribute ansi2knr.1
11001 * Makefile.in (stamp-h.in): Avoid running ./config.status if
11002 stamp-h does not exist yet. This avoids running it a second time
11003 just after the initial ./configure.
11004 Reported by David MacKenzie and Tom McConnell.
11006 * m4.h: Replace the enum debug_info declaration with a series of
11007 #define's. The Ultrix 3.1 compiler would otherwise need casting
11008 (int) to most references, when used in expressions.
11009 Reported by Tom McConnell.
11011 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
11013 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
11014 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
11015 calls the compiler. Previously, FP_PROTOTYPES was only calling
11016 the preprocessor; by not being subject to CFLAGS, this was
11017 discouraging those flags asking for ANSI compilation.
11018 * acconfig.h: Document HAVE_PROTOTYPES.
11019 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
11020 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
11021 Reported by Eric Backus.
11023 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
11024 from the environment. Default CFLAGS to -g if not set.
11025 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
11026 * lib/Makefile.in: Have CFLAGS substituted from configure.
11027 Reported by Eric Backus and Tom McConnell.
11029 * configure.in: m4_undefine changeword before using AC_ENABLE.
11031 * m4.h: Declare prototypes for error (for ANSI compilers only),
11032 prefix_all_builtins and reference_error.
11033 Reported by Tom McConnell.
11035 * input.c (set_word_regexp): Do not try to initialize the array
11036 test from a string, this does not work with non-ANSI compilers.
11037 Reported by Eric Backus.
11039 * Makefile.in (dist): Clean examples/ before saving it.
11040 (distclean-local): Also remove stamp-h.
11041 Reported by Eric Backus.
11043 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
11044 non ANSI compilers.
11045 Reported by Tom McConnell.
11047 * checks/Makefile.in (clean): Depends on mostlyclean.
11048 (mostlyclean): New goal.
11050 1994-06-24 François Pinard <pinard@iro.umontreal.ca>
11052 * Makefile.in (DISTFILES): Distribute install.sh.
11053 * install.sh: New file, copied from elsewhere.
11054 Reported by Assar Westerlund and Kaveh R. Ghazi.
11056 1994-06-23 François Pinard <pinard@iro.umontreal.ca>
11058 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
11059 * acconfig.h: Explain ENABLE_CHANGEWORD.
11061 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
11062 from code provided by Pete Chown]
11063 * m4.h: Add original_text field to u_t variant of union u.
11064 Declare TOKEN_DATA_FUNC macro.
11065 * builtin.c: Declare changeword.
11066 (m4_changeword): New function.
11067 * input.c: Include "regex.h", define variables with word regexps.
11068 (input_init): Initialize the word regexp.
11069 (set_word_regexp): New.
11070 (next_token): Declare local variables, use the previous code if
11071 default_word_regexp is true. Else, match using a new code. Save
11072 the original text.
11073 * macro.c (expand_token): Ship out original text if not a macro
11074 name.
11075 Reported by Krste Asanovic and Pete Chown.
11077 [These modifs all depend upon ENABLE_CHANGEWORD]
11078 * m4.h: Declare external user_word_regexp.
11079 * m4.c: Declare user_word_regexp, and initialize it from
11080 --word-regexp or -W, or NULL if not specified.
11081 * input.c: Use user_word_regexp if specified, instead of
11082 DEFAULT_WORD_REGEXP.
11084 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
11085 agree with it.
11087 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
11088 * checks/Makefile.in: Empty the suffix list.
11089 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
11091 * m4.c: Declare nesting_limit and initialize it to 250.
11092 Implement -LNUMBER or --nesting-limit=NUMBER to change its
11093 value.
11094 * m4.h: Declare nesting_limit as external.
11095 * macro.c (expand_macro): Stop execution whenever nesting limit
11096 is exceeded.
11097 Reported by Bengt Mertensson.
11099 * eval.c (evaluate): Diagnose excess characters in eval input.
11100 Things like `eval(08)' used to return 0 with no diagnostic.
11102 * m4.h: Capitalize first letter of all macro arguments in
11103 definitions.
11105 * m4.c: Declare warning_status, initialize it to 0. Add new
11106 option -E, or --fatal-warnings, which sets warning_status to
11107 EXIT_FAILURE instead.
11108 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
11109 EXIT_FAILURE if not otherwise done by header files.
11110 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
11111 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
11112 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
11113 argument of all M4ERROR calls.
11114 Reported by Noah Friedman.
11116 * examples/incl-test.m4: Renamed from incl_test.m4.
11117 * examples/include.m4: Include incl-test.m4 instead of
11118 incl_test.m4.
11119 * examples/multiquotes.m4: Renamed from multi-quotes.m.
11121 1994-06-22 François Pinard <pinard@iro.umontreal.ca>
11123 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
11124 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
11125 also tested it on a Sun Sparc workstation running SunOS 4.x.
11127 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
11128 49.format check, abusing a `union values' argument with sprintf
11129 without selecting the proper field. Now, save the formatting type
11130 first, delaying the fetch of the corresponding argument.
11131 Reported by Joseph E. Sacco and Tom Quinn.
11133 * format.c (format): Remove const from char *fmt declaration when
11134 not HAVE_EFGCVT, because a NUL may be forced into it.
11136 * m4.h: Declare atof() when not STDC_HEADERS.
11137 Reported by Joseph E. Sacco.
11139 * Regenerate configure using Autoconf 1.11, this corrects a
11140 problem about an incorrect cpp seting on NeXT 3.1.
11141 Reported by Alexander Lehmann.
11143 1994-06-05 François Pinard <pinard@iro.umontreal.ca>
11145 * m4.h (_): Change argument from `x' to `Args'.
11147 1994-04-22 François Pinard <pinard@iro.umontreal.ca>
11149 * m4.h: Rename Args() to _().
11150 * m4.h: Remove extern specifier from all function declarations.
11152 1994-04-22 Jim Avera <jima@netcom.com>
11154 * stackovf.c: New file implementing stack-overflow detection.
11155 * configure.in: Check for getrlimit, sigaction. If all of
11156 standard headers, getrlimit and sigaction, define USE_STACKOVF and
11157 substitute ${U}stackovf.o for STACKOVF.
11158 * acconfig.h: Declare USE_STACKOVF.
11159 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
11160 * m4.h: Declare setup_stackovf_trap().
11161 * m4.c: Call setup_stackovf_trap().
11162 * tests/stackovf_test.sh: New file.
11164 1994-04-13 François Pinard <pinard@iro.umontreal.ca>
11166 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
11168 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
11170 1994-01-30 François Pinard <pinard@iro.umontreal.ca>
11172 * m4.h: Remove definition of volatile, not used anymore.
11173 Reported by Jim Meyering and Joseph E. Sacco.
11175 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
11176 of `if ... else /* nothing */' for if macros.
11177 Reported by Jim Meyering.
11179 * builtin.c (m4_regexp): Reorganize the code for avoiding a
11180 warning from gcc about `repl' possibly used before defined.
11181 Reported by Jim Meyering.
11183 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
11184 Reported by Jim Meyering.
11186 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
11188 * m4.h: Move the conditional definition of volatile after the
11189 inclusion of system files, because they may define it first.
11191 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
11193 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
11194 get around a problem with Alpha make seeing a syntax error, there.
11195 Reported by Vern Paxson.
11197 1994-01-03 François Pinard <pinard@iro.umontreal.ca>
11199 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
11200 Reported by Richard Stallman.
11202 1993-12-25 François Pinard <pinard@iro.umontreal.ca>
11204 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used
11205 instead of AC_HAVE_FUNCS.
11206 Reported by Noah Friedman.
11208 1993-12-01 François Pinard <pinard@iro.umontreal.ca>
11210 * m4.c: Initialize show_help and show_version to zero.
11212 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
11213 Use them in exit() and usage() calls.
11215 1993-11-27 François Pinard <pinard@iro.umontreal.ca>
11217 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
11218 syserr() macro. Delete errref, add reference_error and M4ERROR.
11219 * m4.c: Replace errref, which was returning an input reference
11220 string, with reference_error, which prints it on standard error.
11221 * builtin.c, output.c: Use errno as second parameter to error,
11222 instead of using syserr() with %s.
11223 * *.c: Use M4ERROR instead of error: no more errref() with %s.
11224 Doing so, the program name appears after the input reference
11225 instead of before, which eases M-x next-error processing.
11227 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
11229 * checks/get-them: Escape braces with backslashes in patterns,
11230 because HPUX-9.01 awk needs this.
11231 Reported by Jim Meyering.
11233 1993-11-22 François Pinard <pinard@iro.umontreal.ca>
11235 * builtin.c: Declare "FILE *popen ();".
11237 * m4.h: Remove MESSAGE{,1,2}, WARNING1, FATAL{,1}, INTERNAL_ERROR
11238 macros, replace error_message_prefix() declaration by errref()'s.
11239 Declare xrealloc, for use in errref().
11240 * m4.c: Delete error_message_prefix() function, add errref().
11241 * *.c: Use error() systematically in place of all error macros,
11242 now that error() flushes stdout first. Make needed adjustments.
11244 * m4.h: Remove const in sys_errlist[] declaration, it creates
11245 conflicts on SGI and Alpha.
11246 Reported by Kaveh R. Ghazi.
11248 1993-11-20 François Pinard <pinard@iro.umontreal.ca>
11250 * m4.c: Include <getopt.h> instead of "getopt.h".
11252 * configure.in: Output to config.h. Use HAVE_FUNCS preferably.
11253 * acconfig.h: New, for documenting HAVE_EFGCVT.
11254 * Makefile.in: Distribute acconfig.h, .stamp-h.in and config.h.in,
11255 use them wherever appropriate. Also use -I. for compilations.
11256 * lib/Makefile.in: Use -I.. for compilations.
11257 * *.c: Include <config.h> or "config.h".
11259 * m4.h: Test for HAVE_MEMORY_H instead of NEED_MEMORY_H.
11260 * configure.in: Use AC_HAVE_HEADERS(memory.h), delete AC_MEMORY_H.
11262 1993-11-17 François Pinard <pinard@iro.umontreal.ca>
11264 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
11266 * input.c (input_init): Initialize quote and comment strings
11267 explicitely instead of calling set_quotes and set_comment: by
11268 doing so, we ensure we do not free uninitialized variables.
11270 * checks/check-them: Reverse arguments to both diff, so the
11271 expected is on the left and the obtained on the right.
11273 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
11274 macros. Delete declarations for m4error, warning, fatal and
11275 internal_error, add declaration for error_message_prefix.
11276 * m4.c: Delete m4error, warning, fatal and internal_error
11277 routines, add error_message_prefix routine.
11278 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
11279 warning with WARNING*, fatal with FATAL* and internal_error with
11280 INTERNAL_ERROR*.
11281 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
11282 this is not needed anymore.
11284 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
11285 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
11286 and debug_message, add declaration for debug_message_prefix.
11287 * debug.c: Remove static specifier for FILE *debug declaration.
11288 Delete debug_print and debug_message routines, add
11289 debug_message_prefix routine.
11290 * builtin.c, debug.c: Replace debug_print routine calls with
11291 DEBUG_PRINT* macro calls.
11292 * input.c, path.c: Replace debug_message routine calls with
11293 DEBUG_MESSAGE* macro calls.
11295 * m4.h: Remove inclusion of <varargs.h>.
11296 * debug.c: Include <stdarg.h> or <varargs.h>.
11297 (trace_format): Use stdarg instead of varargs if __STDC__.
11299 * configure.in: Remove checks for vfprintf and _doprnt. These
11300 implementations use varargs tricks which are not portable enough.
11301 * lib/vfprintf.c: Deleted.
11302 * lib/_doprnt.c: Deleted.
11303 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.
11304 Reported by Joel Sherrill.
11306 * path.c (add_include_directory): Use xstrdup.
11308 * builtin.c (find_builtin_by_name): Declare static.
11310 * *.[ch]: Add const to a few "char *" declarations.
11312 * configure.in: Remove commented tests for fileno() and fstat().
11313 * debug.c: Remove comments about HAVE_FILENO and HAVE_FSTAT.

11523 1993-01-17 François Pinard <pinard@iro.umontreal.ca>
11525 * Makefile.in, lib/Makefile.in: Put $(CFLAGS) after $(CPPFLAGS),

11527 Reported by Karl Berry.
11529 1993-01-15 François Pinard <pinard@iro.umontreal.ca>
11531 * lib/vfprintf.c: Stolen from Oleo distribution and adapted. The

11540 1993-01-01 François Pinard <pinard@iro.umontreal.ca>
11542 * Makefile.in, lib/Makefile.in: Reinstate $(CPPFLAGS), use it.

11557 macro.c, output.c, path.c, symtab.c: Change Copyright from
11558 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
11560 * examples/divert.m4: Deleted, this bug has been corrected.

11564 * Makefile.in (clean): Remove clutter from ansi2knr.
11565 Reported by Pierre Gaumond.
11567 1992-12-20 François Pinard <pinard@iro.umontreal.ca>
11569 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
11570 might well use CFLAGS is s/he needs it.
11572 * Makefile.in: Allow installation of info files from a separate
11573 build directory.
11574 Reported by Jason Merrill.
11575 Reported by David MacKenzie.
11576 Reported by Skip Montanaro.
11577 Reported by Erez Zadok.
11578 Reported by Assar Westerlund.
11579 \f
11580 1992-12-19 François Pinard <pinard@iro.umontreal.ca>
11582 * Release 1.0.3
11583 This is still a beta release for the future GNU m4 version 1.1.
11585 * lib/alloca.c: New, from elsewhere.
11586 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
11588 * m4.h: Do not define index/rindex if already defined. If
11589 FALSE/TRUE are already defined, do not redefine them, but merely
11590 define boolean typedef to int.
11592 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
11593 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
11594 because some C compilers do not like connectives with #ifdef.
11595 * m4.h: Define `volatile' only if __GNUC__, instead of once for
11596 __GNUC__ and once for __STDC__.
11597 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
11599 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
11600 Makefile dependencies. Without it, make keeps destroying and
11601 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
11603 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
11604 to diversion/DIVERSION, this was a spelling error.
11606 * m4.c: Declare version[], remove #include "version.h".
11607 * version.h: Deleted.
11608 * Makefile.in: Remove references to version.h.
11610 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
11611 production, by using a simpler and more robust algorithm. This
11612 solves the problem of synclines sometimes written in the middle of
11613 an output line. Delete sync_line() and output_lines variable.
11614 * m4.h: Remove sync_line prototype and output_lines declaration.
11615 * input.c (next_char), output.c (shipout_text): Remove references
11616 to output_lines.
11617 * input.c (push_file, pop_file): Merely put the value -1 in
11618 output_current_line instead of calling sync_line, for delaying a
11619 single `#line NUM FILE' before next output line. Do not test
11620 for sync_output, because this is unnecessary clutter.
11621 * output.c (make_divertion, insert_divertion): Idem.
11622 * input.c: Rename must_advance_line to start_of_input_line, for
11623 consistency.
11625 * debug.c (trace_header): Select a new debug line format, which
11626 better complies with GNU standards for formatting error messages.
11627 With option `-dfl', M-x next-error might be used on the output.
11628 * m4.c (vmesg): Adjust format of error output to GNU standards.
11629 * m4.texinfo: Adjust examples for `make check' to work.
11631 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
11632 case for enum debug_info constants, which were all lower case.
11634 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
11635 re_search_2.
11636 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
11637 collected patches. I tried a few times using newer regex.[ch], it
11638 mysteriously stopped aborting with this one. Insecure feeling...
11639 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
11641 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
11643 * m4.c: Change `--no-warnings' to `--silent'.
11644 Reported by David MacKenzie.
11646 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
11647 leave it off for now. See comment in m4.c for justification.
11648 Reported by David MacKenzie.
11650 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
11651 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
11653 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
11655 * Makefile.in: Ensure recursive cleaning is done before local
11656 cleaning for all clean goals.
11658 * builtin.c (ntoa): Ensure the value is always interpreted as a
11659 signed quantity, whatever the radix is.
11661 1992-11-18 Jim Meyering <meyering@idefix>
11663 * builtin.c, format.c, input.c: Split long lines.
11664 * m4.c: Use typedef macro_definition instead of struct
11665 macro_definition.
11666 * symtab.c: Use typedef symbol instead of struct symbol.
11668 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
11670 * *.[ch]: Remove all trailing whitespace, in code and comments.
11672 * configure.in: Find some awk.
11673 * Makefile.in: Add $(AWK) to MDEFINES.
11674 * checks/Makefile.in: Transmit $(AWK) to get_them.
11675 * checks/get_them: Use $AWK instead of gawk. Add a close in the
11676 awk script when switching files, because without this, mawk runs
11677 out of file descriptors.
11679 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
11681 * Makefile.in (realclean): Delete m4.info*.
11682 Reported by Jim Meyering.
11684 * Makefile.in: Adjust and link with checks/Makefile.
11685 * checks/Makefile.in: New.
11686 * configure.in: Output checks/Makefile.
11688 * checks/get_them: Have the dnl header of each test more
11689 recognizable by next-error, also use a better message.
11691 1992-11-16 Jim Meyering <meyering@idefix>
11693 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
11694 And use that only if __GNUC__ since we're using it's GCC-specific
11695 semantics that tell the compiler the associated function doesn't
11696 return.
11698 * builtin.c (substitute): Don't use character as an array index.
11699 (dumpdef_cmp): Make formal arguments `const void *' to avoid
11700 warnings with gcc -W -Wall on systems with qsort prototype.
11701 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
11702 from gcc -W -Wall.
11704 * eval.c (most functions): Add parentheses to assignments used
11705 as truth values go avoid warnings from gcc -Wall.
11707 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
11708 any functions that don't need external scope.
11710 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
11711 (many functions and arrays): Declare `const'.
11713 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
11715 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
11716 removing the declaration from m4.h. Also rename false to FALSE
11717 and true to TRUE.
11719 * lib/Makefile.in (Makefile): New goal.
11721 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
11722 so heavily loaded. It gets more easily overridable, calling make.
11723 Reported by Jim Meyering.
11725 * Makefile.in (dist): Get .fname from the current directory name,
11726 instead of from version.h. I need updating many files manually,
11727 when the version changes, version.h is just one of them.
11729 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
11731 * m4.h: Remove the tag `boolean' on the enum introducing typedef
11732 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
11733 Reported by Tom McConnell.
11735 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
11737 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
11738 39.cleardiv, which were describing missing or spurious newlines.
11739 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
11740 do not depend on machine word size, `/bin/false' implementation,
11741 or `wc' output format. `make check' is more dependable, now.
11743 * checks/check_them: Summarize the failed tests by listing their
11744 name, at end. If none, issue `All checks successful'. Output
11745 `Checking' instead of `Input file:'.
11747 * checks/get_them, checks/check_them: Reindented.
11749 * Makefile.in (dist): chmod a+r before making the tar file.
11751 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
11753 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
11755 * input.c (next_token): Reinitialize token_buttom just after using
11756 it as a watermark with obstack_free. Or else, a future token, big
11757 enough for triggering reallocation of the obstack chunk, could
11758 void the initialized value of token_buttom, later causing panic in
11759 obstack_free. Rename token_buttom to token_bottom everywhere.
11761 * m4.h: Before declaring errno, first include <errno.h> and
11762 ensure that it does not define errno.
11763 Reported by Richard Stallman.
11765 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
11767 * builtin.c: Define and use DECLARE macro for builtins.
11769 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
11770 argument, this is a common idiom for introducing long comments.
11772 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
11773 arguments. The last argument was silently ignored.
11775 * m4.c (cmd_error): Add a missing semicolon before va_end().
11777 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
11779 * Makefile.in: Now handle protoized sources. Define and use U.
11780 Compile and use ansi2knr with old compilers. Update DISTFILES.
11781 Add `aclocal.m4' to `configure' dependencies.
11782 * ansi2knr.c: New, from Ghostscript distribution.
11783 * configure.in: Define U through FP_PROTOTYPES for old compilers.
11784 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
11785 * aclocal.m4: New, provide FP_PROTOTYPES.
11786 * m4.h: Conditionnaly protoized through Args, save for varags.
11787 * builtin.c: Protoized. Then:
11788 Include <sys/types.h> if size_t is not defined, before "regex.h".
11789 (m4_ifelse): Fetch built-in name properly for diagnostic.
11790 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
11791 (m4_regexp): Add const to `msg' declaration.
11792 (m4_patsubst): Add const to `msg' declaration.
11793 * debug.c: Protoized, save for varargs.
11794 * eval.c: Protoized.
11795 * format.c: Protoized.
11796 * input.c: Protoized.
11797 * m4.c: Protoized, save for varargs. Then:
11798 (xfree): Accept void * instead of char *.
11799 (xmalloc): Return void * instead of char *.
11800 (xrealloc): Accept and return void * instead of char *.
11801 * macro.c: Protoized.
11802 * output.c: Protoized.
