1449 * tests/freeze.at (loading format 1, loading format 2): Update to
1450 test this.
1452 2008-05-10 Eric Blake <ebb9@byu.net>
1454 Detect integer overflow when loading frozen file.
1455 * src/freeze.c (reload_frozen_state) [GET_NUMBER]: Rewrite to fail
1456 immediately on overflow.
1457 * tests/freeze.at (loading format 2): Test this.
1458 Reported by Jim Meyering.
1460 2008-05-08 Eric Blake <ebb9@byu.net>
1462 Stage 23: allow tracing of indirect macro calls.
1463 Track all trace information as part of the argv struct, rather
1464 than temporarily resetting global state. Teach indir to trace
1465 macros that it invokes.
1466 Memory impact: slight penalty, due to larger argv struct.
1467 Speed impact: none noticed.
1468 * m4/m4module.h (m4_input_block): Remove.
1469 (m4_call_info): New opaque type.
1470 (m4_trace_prepare, m4_arg_info): New prototypes.
1471 (m4_macro_call, m4_push_string_finish, m4_input_print): Change
1472 prototypes.
1473 * m4/m4private.h (struct m4_macro_args): Add info field.

1479 printing can be done before finalization.
1480 (struct input_funcs): Add parameter to print_func.
1481 (file_print, string_print, composite_print): Adjust accordingly.
1482 * m4/macro.c (trace_header, trace_flush, trace_pre, trace_post):
1483 Change signatures for stacked trace messages, and for using call
1484 context.
1485 (trace_prepre): Export and rename...
1486 (m4_trace_prepare): ...to this, for use by indir. Alter signature
1487 to use call context.

1508 Test for traceon regression just fixed in branch-1.6.
1509 * doc/m4.texinfo (Trace): Enhance test.
1510 * NEWS: Port news item from branch.
1512 2008-05-05 Eric Blake <ebb9@byu.net>
1514 Stage 22: allow builtin token concatenation outside $@.
1515 Adjust the input and argument parsing engines to append builtins
1516 alongside text. Make define warn when builtins must be
1517 flattened.
1518 Memory impact: slight penalty, with fewer builtins flattened.
1519 Speed impact: slight penalty, from more bookkeeping.
1520 * m4/m4module.h (m4_is_arg_composite): New prototype.
1521 (m4_symbol_value_copy): Change return type.
1522 (m4_arg_text): Add parameter.
1523 (M4ARG): Adjust callers.
1524 * m4/m4private.h: Adjust comments.

1539 * NEWS: Document this change.
1541 2008-05-03 Eric Blake <ebb9@byu.net>
1543 Document define_blind.
1544 * doc/m4.texinfo (Ifelse): Add a new composite macro.
1545 * THANKS: Update.
1546 Suggested by Mike R.
1548 2008-05-01 Eric Blake <ebb9@byu.net>
1550 Avoid -Wshadow compiler warnings.
1551 * m4/output.c (threshold_diversion_CB): s/div/diversion/.
1552 * m4/macro.c (make_argv_ref, arg_symbol, m4_arg_symbol)
1553 (m4_is_arg_text, m4_is_arg_func, m4_arg_text, m4_arg_empty)
1554 (m4_arg_len, m4_arg_func, m4__arg_print, m4_make_argv_ref)
1555 (m4_push_arg, m4__push_arg_quote): s/index/arg/.

1559 Improve debugmode testing, based on recent branch-1.6 regressions.
1560 * doc/m4.texinfo (Debugmode): Enhance tests.

1574 Simplify previous patch.
1575 * tests/m4.in: Compress assignment.
1576 Suggested by Gary V. Vaughan.

1593 SIGPIPE.
1594 * doc/m4.texinfo (Operation modes): Document SIGPIPE behavior.
1595 * THANKS: Update.
1596 Reported by Bob Proulx, via his autobuilder.
1598 2008-04-15 Eric Blake <ebb9@byu.net>

1602 program name.
1603 (HELP_OTHER, PREPARE_TESTS): Document and use $M4.
1604 * tests/builtins.at (patsubst): Avoid space-tab.
1605 (divert, mkdtemp, mkstemp): Adjust tests to use $M4.
1606 * tests/options.at (--debugfile): Likewise.

1608 (fstab): Avoid space-tab.
1609 * Makefile.am (installcheck-local): Accomodate transformed name.
1610 (DISTCHECK_CONFIGURE_FLAGS): Ensure no regressions, by using gm4
1611 during 'make distcheck'.
1612 * cfg.mk: New file, borrowed from branch.
1614 Update prerequisite tools to match recent releases.
1615 * configure.ac (AC_PREREQ): Rely on released autoconf.
1616 (LT_PREREQ): Rely on released libtool.
1617 * tests/testsuite.at (m4_version_prereq): Update dependence.
1618 * bootstrap: Mention prerequisites.
1620 Work around OS/2 limitation of printf(1).
1621 * tests/null.m4: Use m4, not printf, to generate NUL byte.
1622 * tests/null.out: Check for esyscmd failure.
1623 Reported by Elbert Pol.
1625 2008-04-14 Eric Blake <ebb9@byu.net>
1627 Stage 21b: $@ concatenates builtins, m4wrap takes builtins.
1628 Improve arg_print to handle builtin tokens when printing to a
1629 known chain, rather than always flattening builtins. This allows
1630 m4wrap and $@ back-references to handle embedded builtin tokens.
1631 Memory impact: none.
1632 Speed impact: slight penalty, from more bookkeeping.
1633 * m4/m4module.h (m4_push_builtin): Add parameter.
1634 (m4_builtin_print, m4_push_wrapup_init, m4_push_wrapup_finish)
1635 (m4_arg_print, m4_symbol_value_print): Rename and reduce scope...
1636 * m4/m4private.h (m4__builtin_print, m4__push_wrapup_init)
1637 (m4__push_wrapup_finish, m4__arg_print, m4__symbol_value_print):
1638 ...to these, in some cases adding a parameter.
1639 (m4__append_builtin): New prototype.
1640 * m4/builtin.c (m4_builtin_print): Alter signature to print
1641 builtin to a growing symbol chain.
1642 * m4/symtab.c (m4__symbol_value_print): Alter signature.
1643 (m4_symbol_print, dump_symbol_CB): Adjust callers.
1644 * m4/input.c (builtin_peek, builtin_read, builtin_unget)
1645 (builtin_print, builtin_funcs): Delete, handled via composite
1646 blocks now.
1647 (struct m4_input_block): Delete u.builtin member.
1648 (init_builtin_token): Only use composite block.
1649 (m4__append_builtin): New function.
1650 (m4_push_builtin, m4__push_wrapup_init): Alter signature.
1651 (m4__push_symbol): Allow builtin tokens.
1652 (m4__push_wrapup_finish): Rename.
1653 (composite_print, m4_print_token): Adjust callers.
1654 * m4/macro.c (m4_wrap_args, collect_arguments): Allow builtin
1655 tokens.
1656 (m4__arg_print): Alter signature.
1657 (trace_prepre, trace_pre, m4_arg_text, m4_arg_equal): Adjust
1658 callers.
1659 * modules/m4.c (m4wrap): Allow builtin tokens.
1660 (defn, errprint): Adjust callers.
1661 * modules/gnu.c (builtin): Likewise.
1662 * doc/m4.texinfo (M4wrap): New test.
1663 (Debuglen): Adjust expected output.
1665 Stage 21a: Optimize checks for end of input.
1666 Create a new polymorphic input block type, which always fails with
1667 CHAR_EOF, so that remaining input routines no longer have to check
1668 for NULL input block.
1669 Memory impact: none.
1670 Speed impact: noticeable improvement, from fewer conditionals.
1671 * m4/input.c (eof_funcs, input_eof): New objects.
1672 (eof_peek, eof_read, eof_unget): New functions.
1673 (file_clean, m4_push_string_init, pop_input, m4_push_wrapup_init)
1674 (m4_pop_wrapup, next_char, peek_char, unget_input, m4_input_init)
1675 (m4_input_exit): Use placeholder to guarantee non-NULL isp and
1676 wsp.
1677 (next_char): Rename retry to allow_unget, and change sense for
1678 easier manipulation. All callers changed.
1680 Improve OS/2 detection.
1681 * modules/gnu.c (m4_macro_table): Ensure all possible identifiers
1682 are defined, not just the first. The testsuite ensures that
1683 exactly one gets defined.
1684 * m4/system_.h [__EMX__]: OS/2 is not Unix-compatible, no matter
1685 what other pre-defined macros it has.
1686 * THANKS: Update.
1687 Reported by Elbert Pol.
1689 Ensure __m4_version__ is unquoted.
1690 * tests/builtins.at (__m4_@&t@version__): Augment test.
1692 Avoid GNU make failure on tarball.

1701 Adjust all callers.
1702 * tests/others.at (ifndef): New test.
1704 Be namespace clean for M4 version; fixes 2008-04-08 regression.
1705 * configure.ac (version): Rename...
1706 (M4_VERSION): ...to this, since using 'version' broke po.m4.
1708 2008-04-09 Eric Blake <ebb9@byu.net>
1710 Mention 1.4.11 release.
1711 * doc/m4.texinfo (History, Defn, Ifdef, Ifelse, M4wrap)
1712 (Extensions, Improved foreach): Distinguish 1.4.11 and 1.6.
1713 (Format): Add test of C99 hex-float parsing.
1714 * NEWS: Mention 1.4.11 release.
1715 * tests/builtins.at (divert): Add additional test.
1717 2008-04-08 Eric Blake <ebb9@byu.net>
1719 Overhaul inter-version releases to work with git.
1720 * configure.ac (version): New variable, which has nicer version
1721 contents when using git 1.5.5+, hardcoded to 1.9a otherwise.
1722 (TIMESTAMP): Delete, since CVS id expansion died with transition
1723 to git.
1724 (AM_INIT_AUTOMAKE): Use version to decide gnu vs. gnits.
1725 * build-aux/mkstamp: Delete, no longer used.
1726 * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Kill, to speed up
1727 rebuilds when timestamps don't matter.
1728 (MKSTAMP): Delete, no longer used.
1729 (EXTRA_DIST): No longer worry about mkstamp.
1730 (.version): New rule and distributed file.
1731 (doc/m4.1, tests/package.m4): Depend on .version, not
1732 configure.ac, for timestamp.
1733 * ltdl/m4/gnulib-cache.m4: Import git-version-gen module.
1734 * modules/gnu.c (__m4_version__): TIMESTAMP no longer exists.
1735 * src/main.c (main): Likewise.
1737 2008-03-28 Eric Blake <ebb9@byu.net>
1739 Use GNUmakefile module.
1740 * ltdl/m4/gnulib-cache.m4: Import gnumakefile module.
1741 * Makefile.am: Split off maintainer rules...
1742 * maint.mk: ...into this new file.
1744 2008-03-18 Eric Blake <ebb9@byu.net>
1746 Stage 20b: make m4wrap obey POSIX fifo ordering.
1747 Improve input engine to support location changes within symbol
1748 chains, then convert m4wrap to always build symbol chain.
1749 Memory impact: none.
1750 Speed impact: slight penalty, from more m4wrap bookkeeping.
1751 * m4/m4module.h (m4_wrap_args): Add prototype.
1752 * m4/m4private.h (enum m4__symbol_chain_type): Add M4__CHAIN_LOC.
1753 (struct m4__symbol_chain): Add struct u_l.
1754 * m4/input.c (m4_push_wrapup_init, m4_push_wrapup_finish): Use
1755 new link type.
1756 (composite_peek, composite_read, composite_clean): Handle location
1757 link.
1758 * m4/macro.c (m4_wrap_args): New function.
1759 * modules/m4.c (m4wrap): Use it.
1760 * doc/m4.texinfo (M4wrap): Sync with branch and POSIX.
1761 (Extensions): Document extension of multiple arguments.
1762 (Location, Improved m4wrap): Adjust example to match FIFO order.
1763 * tests/builtins.at (wrap): Likewise.
1764 * NEWS: Document this change.
1766 2008-03-17 Eric Blake <ebb9@byu.net>
1768 Stage 20a: reduce unget's in input engine.
1769 Now that out-of-range input placeholders like CHAR_BUILTIN are
1770 consumed outside of next_char, next_token should always consume
1771 rather than peek at the first character. Fewer peeks results in
1772 less ungetc overhead.
1773 Memory impact: none.
1774 Speed impact: noticeable improvement, from fewer function calls.
1775 * m4/input.c (struct input_funcs): Alter read_func prototype.
1776 (next_char, file_read, buildin_read, string_read, composite_read):
1777 Add allow_argv parameter.
1778 (init_builtin_token, init_argv_symbol): Require all prior input to
1779 be consumed.
1780 (m4_skip_line, match_input, consume_syntax): Adjust callers.
1781 (m4__next_token): Consume first byte without peek.
1783 Update for fresh bootstrap.
1784 * ltdl/m4/gnulib-cache.m4: Updated copyright from upstream.
1786 2008-03-15 Eric Blake <ebb9@byu.net>
1788 Document join, in order to fix bug in m4wrap example.
1789 * examples/join.m4: New file.
1790 * examples/wraplifo2.m4: Likewise.
1791 * Makefile.am (EXTRA_DIST): Add new files.
1792 * doc/m4.texinfo (Improved m4wrap): New node.
1793 (Defn, Location): Enhance tests.
1794 (Shift): Document the composite macro join.
1795 (Incompatibilities): Move documentation of LIFO vs. FIFO...
1796 (M4wrap): ...here, to match improved example.
1798 2008-03-13 Eric Blake <ebb9@byu.net>
1800 Stage 19c: allow builtin tokens in more macros.
1801 Allow builtin tokens inside symbol chains, although for now, they
1802 are not allowed inside comments or quotes. Enable builtin token
1803 handling in more macros, if only to consistently diagnose invalid
1804 macro names.
1805 Memory impact: none.
1806 Speed impact: slight impact, due to more bookkeeping.
1807 * m4/m4module.h (m4_symbol_value_lookup, m4_builtin_print): New
1808 prototypes.
1809 * m4/m4private.h (enum m4__symbol_chain_type): Add
1810 M4__CHAIN_FUNC.
1811 (struct m4__symbol_chain): Add builtin member.

1816 (m4__push_symbol): Allow pushing builtin tokens.
1817 (composite_peek, composite_read, composite_unget, composite_clean)
1818 (composite_print): Handle builtin tokens.
1819 (init_builtin_token): Allow builtin tokens from composite input.
1820 (m4__next_token): Flatten builtins inside comment or string.
1821 * m4/macro.c (expand_argument): Strengthen assertion.
1822 (collect_arguments, m4_arg_equal, m4_arg_print, m4_push_args):
1823 Handle builtin tokens.
1824 (arg_symbol): Add parameter, and allow NULL level.
1825 (m4_arg_symbol, m4__push_arg_quote): Adjust callers.
1826 (m4_arg_text): Ensure all builtins have been flattened.
1827 * modules/m4.c (defn, dumpdef, popdef, traceoff, traceon)
1828 (undefine, m4_dump_symbols): Warn on invalid macro names.
1829 (ifdef, ifelse, shift): Handle builtin tokens.
1830 * modules/gnu.c (m4symbols): Likewise.
1831 * doc/m4.texinfo (Defn, Ifdef, Ifelse): Document and test the new
1832 behavior.
1833 (Debuglen): Likewise, and remove xfail.
1834 * NEWS: Mention the change.
1836 Stage 19b: invert sense of bit for handling builtin tokens.
1837 Pass builtin tokens by default, rather than as the exception, so
1838 that the logic can consistently refer to flattening arguments.
1839 Memory impact: none.
1840 Speed impact: none.
1841 * m4/m4module.h (M4BUILTIN_ENTRY): New convenience macro.
1842 (M4_BUILTIN_GROKS_MACRO): Rename...
1843 (M4_BUILTIN_FLATTEN_ARGS): ...and invert sense.
1844 (m4_symbol_value_groks_macro, m4_symbol_groks_macro): Likewise...
1845 (m4_symbol_value_flatten_args, m4_symbol_flatten_args): ...to
1846 this.
1847 * m4/m4private.h (VALUE_MACRO_ARGS_BIT)
1848 (m4_symbol_value_groks_macro): Likewise...
1849 (VALUE_FLATTEN_ARGS_BIT, m4_symbol_value_flatten_args): ...to
1850 this.
1851 * m4/symtab.c (m4_symbol_value_groks_macro): Likewise...
1852 (m4_symbol_value_flatten_args): ...to this.
1853 * m4/macro.c (collect_arguments): Accomodate changed sense.
1854 * m4/module.c (m4__module_open): Require arguments if flattening
1855 is requested.
1856 * m4/input.c (m4_push_string_finish): For now, flatten all
1857 builtins pushed as back-references.
1858 * modules/gnu.c (m4_builtin_table, builtin): Adjust all clients.
1859 * modules/import.c (m4_builtin_table): Likewise.
1860 * modules/load.c (m4_builtin_table): Likewise.
1861 * modules/modtest.c (m4_builtin_table): Likewise.
1862 * modules/mpeval.c (m4_builtin_table): Likewise.
1863 * modules/perl.c (m4_builtin_table): Likewise.
1864 * modules/shadow.c (m4_builtin_table): Likewise.
1865 * modules/stdlib.c (m4_builtin_table): Likewise.
1866 * modules/time.c (m4_builtin_table): Likewise.
1867 * modules/m4.c (m4_builtin_table): Likewise.
1868 (mkstemp): Undo #undef hack from 2006-10-23, now that macro names
1869 are stringized without preprocessor expansion.
1870 * doc/m4.texinfo (Defn): Update comments to match reality.
1871 (Debuglen): Update test now that user macros pass builtin tokens.
1873 Stage 19a: sort and cache builtins loaded by a module.
1874 Rather than repeatedly using dlsym to browse the builtin table,
1875 copy off the table at module load time. Then, the input engine
1876 merely refers to the copy instead of duplicating information.
1877 Memory impact: slight penalty, due to more memory per module, but
1878 offset by less memory in input engine.
1879 Speed impact: slight improvement, due to faster builtin lookups.
1880 * m4/m4module.h (m4_set_symbol_value_builtin): Delete. Use
1881 m4_builtin_find_by_* instead.
1882 (m4_builtin_find_by_func): Change return type.
1883 * m4/m4private.h (m4__builtin): New struct.

1926 Fix nested builtin(`shift',$@) regression from 2008-02-23.
1927 * m4/macro.c (make_argv_ref): Don't output expansion text when
1928 making wrapper for builtin or indir.
1929 * tests/builtins.at (builtin): New test.
1930 * NEWS: Document the fix.
1931 Reported by Andreas Schwab.
1933 2008-03-04 Eric Blake <ebb9@byu.net>
1935 The gnulib module free was deprecated.
1936 * ltdl/m4/gnulib-cache.m4: Remove free module.
1938 2008-02-29 Eric Blake <ebb9@byu.net>
1940 Import news from 1.4.10b.
1941 * NEWS: Update from branch.
1943 2008-02-23 Eric Blake <ebb9@byu.net>
1945 Stage 18: try harder to reuse argv in recursion.
1946 When pushing arguments that contain an existing $@ ref, reuse the
1947 ref rather than creating another layer of wrappers.
1948 Memory impact: noticeable improvement, due to better $@ reuse.
1949 Speed impact: noticeable improvement, due to O(n^2) to O(n)
1950 reduction in unboxed recursion.
1951 * m4/macro.c (make_argv_ref): Avoid wrapping $@ when possible.
1952 (m4_push_args): Let make_argv_ref take care of pending data.
1953 * doc/m4.texinfo (Improved foreach): Tweak wording to match new
1954 performance capability.
1955 * tests/others.at (recursion): Add tests to avoid performance
1956 regression.
1958 2008-02-22 Eric Blake <ebb9@byu.net>
1960 Update NEWS.
1961 * NEWS: Document change to __gnu__ on 2008-02-11.
1963 Stage 17: pass argv through quoted strings.
1964 Allow the concatenation of $@ references with other text input
1965 inside quoted contexts, which requires distinguishing between a
1966 wrapper around many arguments vs. a reference serving as part of a
1967 single argument. Also optimize based on whether argv contains
1968 builtin tokens that might need flattening to the empty string.
1969 Memory impact: noticeable improvement, due to O(n^2) to O(n)
1970 reduction from total reuse of $@ references.
1971 Speed impact: noticeable improvement, due to O(n^2) to O(n)
1972 reduction in boxed recursion.
1973 * m4/m4module.h (m4_arg_equal, m4_arg_len): Add parameter.
1974 (M4ARGLEN): Adjust definition.
1975 * m4/m4private.h (struct m4__symbol_chain): Add has_func member.
1976 (struct m4_symbol_value): Add wrapper and has_func members.
1977 (struct m4_macro_args): Add flatten and has_func members.
1978 * m4/input.c (append_quote_token): Return argv refs inside quoted
1979 strings.
1980 (init_argv_symbol): Populate new fields.
1981 * m4/macro.c (expand_argument, collect_arguments, make_argv_ref)
1982 (m4_make_argv_ref): Likewise.
1983 (arg_symbol, arg_mark, m4_is_arg_text, m4_is_arg_func): Use new
1984 fields.

1986 new parameter.
1987 * modules/m4.c (ifelse): Adjust caller.
1989 2008-02-22 Gary V. Vaughan <gary@gnu.org>
1991 Fix regression in argument collection, from 2008-01-21.
1992 * m4/input.c (m4__next_token): When DEBUG_INPUT is defined,
1993 undo argument collection optimisation for strings, so that
1994 m4_print_token doesn't abort when it otherwise receives an
1995 unprintable M4_SYMBOL_VOID type token.
1997 2008-02-20 Eric Blake <ebb9@byu.net>
1999 Stage 16: cache quotes and improve m4_arg_print.
2000 Cache rather than always copying quotes when pushing $@ refs; in
2001 particular, reconstruct single-byte quotes on the fly. Allow NUL
2002 through m4wrap. Improve sharing of code that prints arguments.
2003 Memory impact: slight improvement, due to cached quotes.
2004 Speed impact: slight improvement, due to less copying.
2005 * m4/m4module.h (m4_symbol_value_print, m4_symbol_print)
2006 (m4_arg_print): Adjust prototypes.
2007 (m4_dump_args): Delete.
2008 (m4_push_wrapup): Split...

2012 member.
2013 (m4__quote_cache, m4__quote_uncache): New prototypes.

2018 (m4_symbol_print, dump_symbol_CB): Adjust all callers.
2019 * m4/utility.c (m4_dump_args): Delete; callers should use
2020 m4_arg_print instead.
2021 * m4/input.c (m4_push_wrapup_init, m4_push_wrapup_finish): Split
2022 implementation, and allow embedded NUL.
2023 (m4_print_token, pop_input, composite_print, composite_peek):
2024 (composite_read, append_quote_token): Adjust all callers.
2025 * m4/macro.c (trace_prepre, m4_arg_text, make_argv_ref):
2026 Likewise.

2042 2008-02-19 Eric Blake <ebb9@byu.net>
2044 Clean up example on filtering defined symbols.
2045 * doc/m4.texinfo (Foreach, Improved foreach): Document another
2046 shortcoming in foreach.m4, and improve filter example by using
2047 foreach2.m4.
2049 * src/main.c (usage): Fix typo.

2073 * doc/m4.texinfo (Improved forloop): Document advantage of $0.
2074 (Improved foreach): Adjust dump from file.
2076 Stage 15: return argv refs back to collect_arguments.
2077 Collect an entire $@ reference at once rather than one argument at
2078 a time, outside of quotes (but inside quotes, $@ is still
2079 flattened for now). The skip_last field allows concatenation of
2080 $@ with other text when collecting arguments.
2081 Memory impact: noticeable improvement, due to better reuse of $@.
2082 Speed impact: noticeable improvement, due to less parsing.
2083 * m4/m4private.h (CHAR_ARGV): New input engine sentinel.
2084 (enum m4__token_type): Add M4_TOKEN_ARGV.
2085 (struct m4__symbol_chain): Add skip_last member to argv link.

2088 (composite_peek, m4__next_token): Add new parameter.
2089 (composite_read, append_quote_token): Support argv in quotes.
2090 (init_argv_symbol): New function.
2091 (m4__push_symbol, match_input, consume_syntax)

2181 * modules/perl.c (perleval): Likewise.
2183 Stage 14b: allow pushing argv references.
2184 Push a $@ reference to the input engine in one go, rather than
2185 pushing each element. For now, argument collection still gets one
2186 argument of a $@ at a time; but the penalties of this patch make
2187 it easier to manage $@ efficiently in future patches.
2188 Memory impact: noticeable penalty, due to larger struct and O(n)
2189 to O(n^2) on unboxed recursion.
2190 Speed impact: noticeable penalty, due to more bookkeeping.
2191 * m4/m4private.h (struct m4__symbol_chain): Add comma and quotes

2200 (m4__arg_adjust_refcount): ...to this new function.
2201 (m4_arg_symbol, m4_make_argv_ref, m4_push_arg): Factor...
2202 (arg_symbol, make_argv_ref, m4__push_arg_quote): ...to these new
2203 helper functions, to add parameters.
2204 (m4_push_args): Adjust caller.
2205 * m4/symtab.c (m4_symbol_value_print): Likewise.
2207 Stage 14a: allow printing argv references.
2208 Refactor symbol-value printing code for better sharing, and to
2209 allow printing a contiguous text representation of a $@ ref.
2210 Memory impact: none.
2211 Speed impact: none.
2212 * m4/m4module.h (m4_arg_print): New prototype.
2213 (m4_symbol_value_print): Alter prototype.
2214 * m4/input.c (struct input_funcs): Add parameter to peek_func.
2215 (file_peek, builtin_peek, string_peek): Ignore new parameter.
2216 (composite_peek): Ignore new parameter, for now.
2217 (composite_clean, pop_input): Rework to minimize indirection, and
2218 to avoid infinite recursion in next patch.
2219 * m4/macro.c (trace_prepre, trace_pre): Adjust callers.
2220 (m4_arg_print): New function.
2221 * m4/symtab.c (m4_symbol_value_print): Update signature.

2229 2008-01-31 Eric Blake <ebb9@byu.net>
2231 Kill hack for M4 1.4.4.
2232 * configure.ac (AM_GNU_GETTEXT_INTL_SUBDIR): Delete, now that

2271 2008-01-27 Eric Blake <ebb9@byu.net>
2273 Stage 13: push composite text tokens.
2274 Support pushing composite tokens, allowing back-references to be
2275 reused through multiple macro expansions. Add hueristic that
2276 avoids creating new reference when pushing existing references.
2277 Memory impact: noticeable improvement due to better reference
2278 reuse, except for O(n) to O(n^2) copying in boxed recursion.
2279 Speed impact: slight penalty, due to more bookkeeping.
2280 * m4/m4private.h (m4__push_symbol): Adjust prototype.
2281 * m4/input.c (m4__push_symbol): Add parameter, and support

2318 Alter signatures.
2319 * m4/input.c (string_print, composite_print, m4_input_print):
2320 All callers updated.

2325 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
2326 (m4_get_syntax_comments): Likewise.
2327 * m4/macro.c (trace_prepre, trace_pre, m4_push_args): Likewise.
2328 * m4/output.c (m4_shipout_string, m4_shipout_string_trunc):
2329 Likewise.
2330 * modules/m4.c (dumpdef, m4_make_temp): Likewise.
2331 * src/freeze.c (produce_frozen_state): Likewise.
2332 * tests/freeze.at (reloading unknown builtin): Update test.
2334 Stage 12a: make m4_symbol_chain a union.
2335 Shrink size of symbol chains by using a union.
2336 Memory impact: slight improvement, due to smaller struct.
2337 Speed impact: slight improvement, due to less bookkeeping.
2338 * m4/m4private.h (enum m4__symbol_chain_type): New enum.
2339 (struct m4_symbol_chain): Rename...
2340 (struct m4__symbol_chain): ...to this, since it is internal.
2341 * m4/symtab.c (m4_symbol_value_copy, m4_symbol_value_print): All
2342 callers updated.
2343 * m4/input.c (struct m4_input_block, m4__push_symbol)
2344 (composite_peek, composite_read, composite_unget)
2345 (composite_clean, composite_print, m4__make_text_link)
2346 (append_quote_token): Likewise.
2347 * m4/macro.c (expand_macro, arg_mark, m4_arg_symbol, m4_arg_text)
2348 (m4_arg_equal, m4_arg_len, m4_make_argv_ref, m4_push_arg)
2349 (m4_push_args): Likewise.
2351 2008-01-23 Eric Blake <ebb9@byu.net>
2353 Adjust to recent libtool interface change.
2354 * configure.ac (LT_PREREQ): Require bleeding-edge libtool.
2355 (LT_WITH_LTDL): Delete, now that it is obsolete.
2356 (LTDL_INIT): Use new libtool macro.
2358 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2359 and Eric Blake <ebb9@byu.net>
2361 Rely on newer automake.
2362 * configure.ac (AM_INIT_AUTOMAKE): Require 1.10.1, and add lzma
2363 distribution.
2364 * bootstrap: Update automake requirement.
2365 (func_version): Fix --version output, broken since 2007-08-06.
2366 * HACKING: Likewise. Add lzma requirement.
2367 * Makefile.am (clean-local-src): Not needed any more with newest
2368 Automake.
2369 (clean-local): Adjust.
2370 * TODO: Remove completed item.
2372 2008-01-22 Eric Blake <ebb9@byu.net>
2374 Doc tweak.
2375 * doc/m4.texinfo (Renamesyms): Avoid underfull hbox, and improve
2376 example.
2378 2008-01-21 Eric Blake <ebb9@byu.net>
2380 Stage 11: full circle for single argument references.
2381 Pass quoted strings through to argument collection in a single
2382 action, so that an argument can be reused throughout macro
2383 recursion if it remains unchanged.
2384 Memory impact: noticeable improvement, due to more reuse in
2385 argument collection stacks; O(n^2) to O(n) on boxed recursion.
2386 Speed impact: noticeable improvement, due to less copying.
2387 * m4/m4module.h (m4_arg_text): Add parameter.
2388 (M4ARG): Adjust.
2389 * m4/m4private.h (CHAR_QUOTE): New input engine sentinel.
2390 (m4__make_text_link): New prototype.
2391 (struct m4_symbol_chain): Add quote_age member.
2392 (struct m4_symbol_value): Add end member to chained symbol.
2393 (struct m4_macro_args): Add wrapper member.
2394 * m4/symtab.c (m4_symbol_value_print): Print composite tokens.
2395 (m4_symbol_value_copy, m4_symbol_value_delete): Recognize
2396 composite tokens.
2397 * m4/input.c (make_text_link): Rename...
2398 (m4__make_text_link): ...to this, and export.
2399 (m4_push_string_finish): Adjust caller.
2400 (make_text_link, m4__push_symbol): Update new field.
2401 (file_read, builtin_read, string_read, composite_read, next_char):
2402 Add parameter.
2403 (m4_skip_line, match_input, consume_syntax): Adjust callers.
2404 (append_quote_token): New function.
2405 (m4__next_token): Pass quoted strings onto argument collection.
2406 (m4_print_token) [DEBUG_INPUT]: Update.
2407 * m4/macro.c (expand_argument): Collect composite arguments.
2408 (collect_arguments): Update new field.
2409 (expand_macro): Reduce ref-count of back-references after use.
2410 (arg_mark, m4_arg_symbol, m4_make_argv_ref): Adjust to new member
2411 names.
2412 (m4_is_arg_text): Also recognize composite symbols as text.
2413 (m4_arg_text, m4_arg_len): Merge composite symbols as needed.
2414 (m4_arg_equal): Compare composite symbols.
2415 (m4_push_arg, m4_push_args): Handle composite symbols.
2416 (m4_arg_symbol): Relax assertion.

2421 2008-01-16 Eric Blake <ebb9@byu.net>
2423 Stage 10: avoid extra copying of strings and comments.
2424 When collecting tokens that are immune to further expansion, avoid
2425 copying data from one obstack to another by outputting it into the
2426 destination obstack to begin with. Also reduce copying done in
2427 format builtin.
2428 Memory impact: slight improvement, due to better obstack usage.
2429 Speed impact: noticeable improvement, due less data copying.
2430 * ltdl/m4/gnulib-cache.m4: Import intprops and vasnprintf-posix
2431 modules.
2432 * m4/m4private.h (m4__token_type): Adjust prototype.
2433 * m4/input.c (m4__next_token): Support new parameter.
2434 * m4/macro.c (m4_macro_expand_input, expand_token)
2435 (expand_argument, collect_arguments): Adjust callers.
2436 * modules/m4.c (ntoa): Tighten buffer size.
2437 * m4/output.c (m4_tmpname): Guarantee no buffer overflow.
2438 * modules/format.c (arg_int, arg_long, arg_double): New helper
2439 functions, to detect overflow or unparsed characters.
2440 (ARG_INT, ARG_LONG, ARG_STR, ARG_DOUBLE): Adjust to check for
2441 missing or excess arguments.
2442 (format): Likewise, and also output directly into obstack if there
2443 is room.
2444 * doc/m4.texinfo (History): Update for new year.
2445 (Format): Test for new warnings.
2447 2008-01-15 Eric Blake <ebb9@byu.net>
2449 * TODO: Update with some newer URLs.
2451 Verify linear `index'.
2452 * tests/builtins.at (index): New test.
2453 (translit): Make test take longer, to make quadratic algorithms
2454 more apparent.
2456 2007-12-20 Eric Blake <ebb9@byu.net>
2458 Stage 9: share rather than copy single-arg refs.
2459 Use hooks of previous patch to create back-references to arguments
2460 in the input engine, and inline short text rather than always
2461 creating a FIFO link. Also start testing embedded NUL behavior.
2462 Until the argument collection engine also shares references, the
2463 memory usage increases.
2464 Memory impact: noticeable penalty, due to longer life of argv
2465 changing O(n) to O(n^2) on boxed recursion.
2466 Speed impact: slight improvement, due less data copying.
2467 * ltdl/m4/gnulib-cache.m4: Import memmem and quote modules.
2468 * m4/m4module.h (m4_arg_scratch): New prototype.
2469 * m4/m4private.h (m4__push_symbol): Add parameter.
2470 (m4_arg_scratch): Add fast accessor.
2471 (struct m4): Add expansion_level member, taken...
2472 * m4/macro.c (expansion_level): ...from here. Adjust all users.
2473 (expand_argument): Minor cleanup.
2474 (expand_macro): Track scratch space per macro call.
2475 (m4_arg_scratch): New function.
2476 (m4_make_argv_ref): Call new function.
2477 (m4_push_arg): Push reference to $0.
2478 (m4_push_args): Rework separator usage, since separators will
2479 usually be inlined.
2480 (process_macro): Allow embedded NUL.
2481 * m4/input.c (INPUT_INLINE_THRESHOLD): New define.
2482 (m4__push_symbol): Add parameter. Inline short strings, and save
2483 references through rescanning.
2484 * m4/symtab.c (m4_set_symbol_value_text): Weaken assertion.
2485 * modules/m4.c (errprint, index): Handle NUL transparently.
2486 (dumpdef, translit): Use scratch space, rather than expansion
2487 stack.
2488 * modules/gnu.c (renamesyms, m4symbols): Likewise.
2489 * tests/others.at (nul character): New test.
2490 (iso8859): Quote absolute file name, remove XFAIL.
2491 * tests/iso8859.m4: Avoid raw NUL in output.
2492 * tests/null.m4: New file.
2493 * tests/null.out: Likewise.
2494 * tests/null.err: Likewise.
2495 * Makefile.am (OTHER_FILES): Distribute new files.
2496 * .gitattributes: Treat new files as text.
2498 2007-12-17 Eric Blake <ebb9@byu.net>
2500 Stage 8: extend life of references into argv.
2501 Add hooks to lengthen the lifetime of arguments reused in a macro
2502 expansion, rather than always discarding arguments at the end of
2503 expand_macro. Rework the expand_macro obstacks to handle longer
2504 lifetimes. For now, the hooks remain unused.
2505 Memory impact: slight penalty, due to larger structs.
2506 Speed impact: slight penalty, due to more bookkeeping.
2507 * m4/system_.h (obstack_regrow): Delete.
2508 * m4/m4private.h (struct m4_symbol_chain): Add level field.
2509 (m4__push_symbol): Adjust prototype.
2510 (m4__adjust_refcount): New prototype.
2511 (DEBUG_MACRO) [DEBUG]: New debug control.
2512 (struct m4__macro_arg_stacks): New structure.
2513 (struct m4): Add arg_stacks, stacks_count fields.
2514 * m4/m4module.h (m4_make_argv_ref): Add parameter.
2515 * m4/macro.c (argc_stack, argv_stack): Delete, replaced by
2516 context->arg_stacks.
2517 (m4_macro_expand_input) [DEBUG_MACRO]: Add debug hooks,
2518 conditional on M4_DEBUG_MACRO envvar.
2519 (collect_arguments): Adjust signature.
2520 (expand_macro): Rework obstack handling.
2521 (m4__adjust_refcount, arg_mark): New functions.
2522 (m4_make_argv_ref): Populate new field.
2523 (m4_push_arg, m4_push_args): Track inuse.
2524 (process_macro): One less cast.
2525 * m4/m4.c (m4_delete): Clean up arg_stacks.
2526 * m4/input.c (make_text_link): Use new field.
2527 (m4__push_symbol, file_clean): Update signature.
2528 (composite_read): Bump refcount when done with reference.
2529 (composite_clean): New function.
2530 (pop_input): Adjust caller.
2531 * m4/debug.c (m4_debug_message): Make assertion match comment.
2532 * modules/gnu.c (builtin, indir): Adjust callers.
2533 * tests/builtins.at (ifelse): New test.
2534 (exp): Move and rename...
2535 * tests/others.at (countdown): ...to this.
2536 * doc/m4.texinfo (Improved foreach): Fix tracing usage in
2537 example.
2539 2007-12-13 Eric Blake <ebb9@byu.net>
2541 Yet more rewording.
2542 * doc/m4.texinfo (Inhibiting Invocation): Missed one instance in
2543 the previous patch.
2545 * THANKS: Update.
2547 2007-12-13 Paolo Bonzini <bonzini@gnu.org> (tiny change)
2549 * doc/m4.texinfo (Inhibiting Invocation): Fix quoting of a quoting
2550 example.
2551 Reported by Giovanni Toffetti.
2553 2007-12-11 Eric Blake <ebb9@byu.net>
2555 Stage 7: use chained input support in input parser.
2556 Allow the LIFO input engine to rescan a macro expansion composed
2557 of smaller chunks of FIFO data, rather than the old approach of a
2558 monolithic string. For now, all chunks are still copied.
2559 Memory impact: slight penalty, due to FIFO chain overhead.
2560 Speed impact: slight penalty, due to extra bookkeeping.
2561 * m4/m4private.h (m4__push_symbol): New prototype.
2562 (struct m4_symbol_chain): Add const-safety.
2563 * m4/symtab.c (m4_symbol_value_print): Simplify.
2564 (dump_symbol_CB): Update caller.
2565 * m4/input.c (struct m4_input_block): Alter u_c member, first
2566 introduced 2006-10-25, but unused until now.
2567 (composite_peek, composite_read, composite_unget)
2568 (composite_print, init_builtin_token): Rewrite accordingly.
2569 (m4_push_wrapup): No longer need trailing NUL.
2570 (m4__push_symbol, make_text_link): New functions.
2571 (m4_push_string_finish): Use them.
2572 * m4/macro.c (m4_push_arg, m4_push_args): Likewise.
2573 (expand_macro): Simplify logic of nesting_limit.
2574 * src/main.c (main): Likewise.
2575 * doc/m4.texinfo (Dumpdef): Augment test.
2577 2007-12-08 Eric Blake <ebb9@byu.net>
2579 Stage 6: convert builtins to push arg at a time.
2580 Add new methods to factor all builtins whose expansion includes an
2581 argument, making back-reference creation easier in future patches.
2582 Factor out length-limited printing to obstacks, and use -1 rather
2583 than 0 for unlimited length.
2584 Memory impact: none.
2585 Speed impact: slight improvement, due to better code sharing.
2586 * m4/m4module.h (m4_shipout_text): Rename...
2587 (m4_divert_text): ...to this, to avoid confusion with m4_shipout_*
2588 that does not worry about sync lines.
2589 (m4_shipout_string_trunc): New prototype.
2590 * m4/output.c (m4_shipout_text): Rename...
2591 (m4_divert_text): ...to this.
2592 (m4_shipout_string): Move guts...
2593 (m4_shipout_string_trunc): ...to this new function.
2594 * m4/macro.c (m4_push_arg, m4_push_args): New functions.
2595 (expand_token, process_macro): Update callers.
2596 * m4/input.c (string_print): Likewise.
2597 * modules/m4.c (ifdef, ifelse, shift, substr, translit, divert):
2598 Likewise.
2599 * modules/gnu.c (patsubst): Likewise.
2600 (debuglen): Use SIZE_MAX for unlimited debug length.
2601 * src/main.c (main): Likewise.
2602 * m4/m4.c (m4_create): Default max_debug_length to SIZE_MAX, not
2603 zero.
2605 2007-12-07 Eric Blake <ebb9@byu.net>
2607 Minor security fix: Quote output of mkstemp.
2608 * modules/m4.c (m4_make_temp): Produce quoted output.
2609 * doc/m4.texinfo (Mkstemp, Mkdtemp): Update the documentation and
2610 tests.
2612 Stage 5: add notion of quote age.
2613 Cache the quoting rules that were in effect when a string was
2614 parsed, to avoid reparsing that string if no changequote or other
2615 quote age change took place in the meantime. A quote_age of 0 is
2616 always safe, but does not benefit from caching.
2617 Memory impact: slight improvement, due to smaller struct in input
2618 engine.
2619 Speed impact: slight penalty, due to more bookkeeping.
2620 * m4/m4module.h (m4_get_symbol_value_quote_age): New prototype.
2621 (m4_set_symbol_value_text): Adjust prototype.
2622 (m4_has_syntax): Factor out the unsigned char cast.
2623 * m4/m4private.h (struct m4_syntax_table): Add syntax_age and
2624 quote_age members.
2625 (m4__quote_age, m4__safe_quotes): New accessor macros, no need for
2626 functions at this point.

2628 member.
2629 (m4_set_symbol_value_text): Adjust fast accessor.
2630 (m4_get_symbol_value_quote_age): New fast accessor.
2631 * m4/symtab.c (m4_set_symbol_value_text): Add parameter.
2632 (m4_get_symbol_value_quote_age): New function.
2633 (m4_symbol_value_copy): Adjust callers.
2634 * m4/macro.c (expand_token): Add parameter, and track quote age.
2635 (expand_argument, collect_arguments): Track quote age.
2636 (m4_macro_expand_input, process_macro, m4_make_argv_ref)
2637 (m4_macro_expand_input): Update callers.
2638 (m4_arg_text, m4_arg_len, m4_arg_func): Abort on type mismatch.
2639 * m4/input.c: Comment cleanups.
2640 (struct m4_input_block): Reduce size.
2641 (m4__next_token): Report quote age.

2645 * m4/syntax.c (m4_set_syntax): Initialize and update quote age.
2646 (m4_set_quotes, m4_set_comment): Detect no-op changes, and update
2647 quote age.
2648 (set_quote_age): New helper function.
2649 (check_is_single_quotes, check_is_single_comments): Adjust
2650 callers.
2651 * src/freeze.c (reload_frozen_state): Likewise.
2652 * src/main.c (main): Likewise.
2653 * modules/m4.c (define, pushdef): No need to set macro text.
2654 * tests/builtins.at (changequote, defn): New tests.
2655 * examples/wrapfifo.m4: New file.
2656 * examples/wraplifo.m4: New file.
2657 * Makefile.am (dist_pkgdata_DATA): Distribute new examples.
2659 2007-12-04 Eric Blake <ebb9@byu.net>
2661 Fix builds with OpenBSD make.
2662 * Makefile.am (HELP2MAN): New macro.
2663 (dist_man_MANS, doc/m4.1): Fix rules for building m4.1 into
2664 srcdir.
2665 * README: Update copyright.
2666 * HACKING: Mention help2man and makeinfo dependencies.
2668 2007-11-29 Eric Blake <ebb9@byu.net>
2670 Stage 4: route indir, builtin through ref; make argv opaque.
2671 Finish making struct opaque to all but the input engine, by
2672 reworking obstack usage in expand_macro to better support creation
2673 of a $@ reference. Canonicalize the empty argument, to allow
2674 pointer comparison optimizations.
2675 Memory impact: slight penalty, due to larger struct.
2676 Speed impact: slight improvement, due to fewer function calls.
2677 * m4/system_.h (obstack_regrow): Fix precedence.
2678 * m4/m4module.h (m4_arg_equal, m4_arg_empty, m4_make_argv_ref):
2679 New prototypes.
2680 (struct m4_macro_args): Move...
2681 * m4/m4private.h (struct m4_macro_args): ...here, making it opaque
2682 to modules. Add has_ref member.
2683 (bool_bitfield): New helper typedef.
2684 (struct m4_symbol_chain): Add flatten and len members.
2685 * m4/macro.c (empty_symbol): New placeholder, for optimizing
2686 comparison with empty string.
2687 (m4_macro_expand_input): Initialize it.
2688 (collect_arguments): Alter signature, and populate new fields.
2689 (trace_pre, trace_post): Remove redundant parameter.
2690 (expand_macro): Alter handling of obstacks.
2691 (m4_arg_symbol): Account for wrapped argv.
2692 (m4_arg_equal, m4_arg_empty, m4_make_argv_ref): New methods.
2693 (m4_arg_text, m4_arg_len, m4_arg_func): Use new methods.
2694 * modules/m4.c (ifelse, syscmd): Likewise.
2695 * modules/evalparse.c (m4_evaluate): Likewise.
2696 (undefine, popdef, m4_dump_symbols): Optimize.
2697 * modules/gnu.c (builtin, indir, esyscmd, debugfile): Use new
2698 methods.
2699 (changesyntax, regexp): Optimize.
2700 * m4/output.c (diversion_storage): Use typedef.
2702 Stage 3b: cache length, rather than computing it, in modules.
2703 Use cached token length in builtins and output engine.
2704 Memory impact: none.
2705 Speed impact: noticeable improvement, due to fewer function calls.
2706 * m4/hash.c (m4_hash_remove): Avoid double free on remove
2707 failure.
2708 * m4/output.c (m4_shipout_string): Change semantics of len param.
2709 (m4_shipout_int): Use cached length.
2710 * m4/input.c (m4_push_string_finish): Likewise.
2711 * modules/m4.h (m4_make_temp_func): Add parameter.
2712 * m4/macro.c (expand_token, m4_arg_len): Use cached length.
2713 (collect_arguments, expand_macro): Alter signature.
2714 (trace_format): Don't use out-of-scope buffer.
2715 (process_macro): All callers changed.
2716 * m4/utility.c (m4_dump_args): Likewise.
2717 * m4/symtab.c (m4_symbol_value_print): Likewise.
2718 * modules/gnu.c (__file__, __program__, builtin, indir)
2719 (m4symbols, mkdtemp, regexp_compile, regexp_substitute,
2720 renamesyms, patsubst, regexp, regexp_compile): Likewise.
2721 * modules/load.c (m4modules): Likewise.
2722 * modules/m4.c (defn, m4wrap, maketemp, m4_make_temp)
2723 (numb_obstack, ifdef, ifelse, divert, len, substr): Likewise.

2730 * tests/builtins.at (mkstemp): Likewise.
2731 * tests/others.at (iso8859): XFAIL this test, now that
2732 length-based handling allows NUL through part but not all of M4.
2734 2007-11-28 Eric Blake <ebb9@byu.net>
2736 Stage 3a: cache length, rather than computing it, in libm4.
2737 Cache the length of a token in the input engine and symbol table,
2738 to avoid repeating lots of strlen calls. Additionally, by using
2739 obstack length rather than strlen, the input engine can now
2740 support embedded NUL.
2741 Memory impact: slight penalty, due to larger struct.
2742 Speed impact: slight improvement, due to fewer function calls.
2743 * m4/m4module.h (struct m4_macro_args): Cache length.
2744 (m4_get_symbol_len, m4_get_symbol_value_len): New accessors.

2752 (string_unget, string_print, m4_push_string_finish)
2753 (m4_push_wrapup): Track length of string input.
2754 (m4__next_token): Adjust all users of symbol text to track length,
2755 too.
2756 * m4/macro.c (expand_argument, collect_arguments): Likewise.

2766 Adjust implementation.
2768 2007-11-27 Eric Blake <ebb9@byu.net>
2770 Stage 2: use accessors, not direct reference, into argv.
2771 Outside of macro.c, use accessor methods rather than direct access
2772 into the argv struct.
2773 Memory impact: none.
2774 Speed impact: slight penalty, due to increased function calls.
2775 * m4/m4private.h (m4_arg_argc): New fast accessor.
2776 * m4/m4module.h (m4_arg_argc, m4_arg_symbol, m4_is_arg_text)
2777 (m4_is_arg_func, m4_arg_text, m4_arg_len, m4_arg_func): New
2778 prototypes.
2779 (m4_builtin_func, M4BUILTIN, M4BUILTIN_HANDLER, m4_dump_args)
2780 (m4_macro_call): Make argc unsigned.
2781 (M4ARG): Use new accessors.
2782 * modules/m4.c (define, pushdef): Likewise.

2795 usage.
2797 2007-11-24 Eric Blake <ebb9@byu.net>
2799 Stage 1: convert m4_symbol_value** into new object.
2800 Pass a variable-size wrapper structure instead of an array to
2801 builtins, so that subsequent optimizations in the structure need
2802 not impact every builtin client.
2803 Memory impact: slight penalty, since struct is larger than array.
2804 Speed impact: slight penalty, due to increased bookkeeping.
2805 * ltdl/m4/gnulib-cache.m4: Import flexmember module.
2806 * m4/m4module.h (m4_macro_args): New type, will be opaque to
2807 modules later.

2828 implementation.
2829 * m4/macro.c (m4_macro_call): Adjust callers.
2830 * modules/gnu.c (builtin, debuglen): Likewise.

2871 2007-11-14 Eric Blake <ebb9@byu.net>
2873 Handle some defn corner cases differently.
2874 * doc/m4.texinfo (Defn): Update documentation; although this still
2875 doesn't match the branch, since it may be changed before 2.0.
2876 * m4/macro.c (expand_argument): Consistently ignore builtins in
2877 concatenation contexts.
2878 * m4/m4private.h (m4__symbol_type): Fix C89 compliance bug.
2880 2007-11-13 Eric Blake <ebb9@byu.net>
2882 Note: Patches titled Stage 0 through N form a series of patches
2883 which decreases the algorithmic complexity of tail recursion in
2884 macro expansions from O(n^2) to O(n) in both time and memory, then
2885 performs cleanups, such as handling of embedded NUL, made easier
2886 by the code refactoring.
2888 Stage 0: Fix memory leak in tail recursion.
2889 Free expansion text in the input engine as soon as it is parsed,
2890 rather than when the recursive expansion completes.

3170 2007-09-03 Gary V. Vaughan <gary@gnu.org>
3172 Work around a bug in darwin's awk:
3174 * bootstrap (func_get_translations): Use $AWK instead of raw
3175 `awk' so that the user can use an alternative implementation
3176 if the first awk in PATH doesn't behave as expected.
3177 (func_get_translations): The first awk script mangles the last
3178 entry passed to it for at least the awk implementation shipped
3179 with Darwin 8.10.1. Capture $3 into a variable too to work-
3180 around that problem.
3182 2007-08-29 Gary V. Vaughan <gary@gnu.org>
3184 As gnulib xstrtol is only used by main, and unconditionally pulls
3185 in a copy of getopt, undo bootstrap change from 2007-08-11 below,
3186 and copy the xstrtol code into src/ so that main() can use it
3187 without pushing the extra code into libm4:
3189 * bootstrap (src_modules): Add getopt and xstrtol modules.
3190 * Makefile.am (src_m4_SOURCES): Add xstrtol sources.
3191 * po/POTFILES.in: Move gnu/xstrtol-error.c to src/xstrtol-error.c.
3193 2007-08-11 Eric Blake <ebb9@byu.net>
3195 Another upstream xstrtol change.
3196 * po/POTFILES.in: Track changes in files containing messages.
3197 * bootstrap (src_modules): getopt is now pulled into libgnu.a, no
3198 need to grab it separately.
3199 * src/main.c (OPT_STR, LONG_OPT_STR, short_opt_str, OPT_STR_INIT):
3200 No longer needed.
3201 (size_opt): Adjust to latest xstrtol interface.

3215 for tracking long options.
3216 (main): Track which long option was used.

3218 in error message.
3219 (deprecated options): Test that --arglength spelling shows up in
3220 error message.

3584 M4 was designed to have a small number of header files defining
3585 the interfaces to several source files each. Keeping this in
3586 mind allows us to tidy things up considerably. Having done this,
3587 it becomes clear that some of the installed headers reference
3588 other headers which are not installed (but that's another patch):
3590 * m4/m4private.h (stdio--.h, stdlib--.h, unistd--.h): Moved from
3591 here...
3592 * m4/system_.h (gnu/stdio--.h, gnu/stdlib--.h, gnu/unistd--.h):
3593 ...to here, so client modules can benefit too.

5637 The regs_allocated field in a struct re_pattern_buffer refers
5638 to the state of a particular re_registers struct when used in
5639 successive matches using the same compiled pattern. Avoid a

5672 * Makefile.am (src_m4_DEPENDENCIES): Make dependency explicit.
5673 (clean-local): Split into and depend upon...
5674 (clean-local-tests, clean-local-src): ...these two. The latter
5675 removes the libtool object directory below `src', to work around
5676 a buglet in Automake, failing to list it.
5677 (EXTRA_DIST): Distribute modules/perl.c.
5679 2006-06-19 Eric Blake <ebb9@byu.net>
5681 * Makefile.am ($(srcdir)/doc/m4.1): No need to list $(srcdir) in
5682 right side of dependency; VPATH does that.

5684 (EXTRA_DIST): Distribute stamp-vcl.
5685 Reported by Ralf Wildenhues.
5686 (TESTSUITE): Revert earlier change that used absolute path, as
5687 that broke 'make dist' in VPATH. Stick with $(srcdir) instead.
5688 (EXTRA_DIST): Revert earlier change of $(TESTSUITE).
5689 (TESTS_ENVIRONMENT) [USE_GMP]: Revert earlier addition, since
5690 atlocal takes care of it instead.
5691 (check-local, installcheck-local, clean-local): Inline absolute
5692 path to testsuite here, rather than relative path to testsuite
5693 elsewhere.
5695 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5697 * m4/m4private.h (DELETE): Cast away const here...

5710 2006-06-16 Eric Blake <ebb9@byu.net>
5712 Follow recommendations from autoconf manual for autotest.
5713 * Makefile.am (TESTSUITE): Factor the $(srcdir) out of uses, and
5714 turn it into an absolute path until autotest provides an option

5716 throughout.
5717 (TESTS_ENVIRONMENT) [USE_GMP]: Inform testsuite about GMP.
5718 (check-recursive): Delete unused target.
5719 ($(TESTSUITE)): Atomically update testsuite.

5745 conditional.
5746 * ltdl/m4/m4-gnulib.m4: Delete, no longer needed.
5748 Reduce compiler warnings. Inside GMP, mpq_t is an array type, so
5749 const mpq_t is not assignable from plain mpq_t. Avoid
5750 type-punning warnings caused trying to mix these types.
5751 * modules/mpeval.c (numb_ior, numb_eor, numb_and, numb_lshift),
5752 (numb_rshift, numb_divide, numb_modulo): Remove const qualifier.

5776 * Makefile.am (AM_CPPFLAGS): Add $(LTDLINCL), so the right
5777 ltdl.h is used.
5779 * bootstrap: Do not run libtoolize manually, this is done
5780 correctly by autoreconf. Invoke autoreconf with --no-recursive
5781 to avoid unnecessary rerunning of autotools for libltdl.
5783 2006-06-13 Eric Blake <ebb9@byu.net>
5785 * THANKS: Update.
5787 2006-06-12 Eric Blake <ebb9@byu.net>
5789 * m4/output.c [HAVE_MKTEMP]: Gnulib provides mkstemp, so don't
5790 bother with mktemp.
5791 * src/m4.h: Don't declare mktemp.
5792 * m4/input.c (m4__next_token): Avoid bzero.
5793 * configure.ac (AC_CHECK_FUNCS): Remove obsolete checks.
5794 * Makefile.am (doc/m4.1): Depend on installed help2man, rather
5795 than distributing outdated helptoman.pl.

5798 2006-06-10 Eric Blake <ebb9@byu.net>
5800 * README (Patches): Document the current dependence on CVS

5810 (AC_CHECK_HEADERS, AC_FUNC_ALLOCA, AC_FUNC_VPRINTF): Remove checks
5811 done by gnulib or automake, or which autoconf has declared
5812 obsolete.

5826 worthwhile.
5827 * ChangeLog: Change encoding to UTF-8.
5829 Avoid compiler warnings.
5830 * m4/macro.c (trace_format): Don't mark this as a printf format,
5831 since we don't accept the same set of modifiers as printf. It
5832 would be nice if gcc let us specify a custom format archetype.
5833 * src/main.c (main): Cast away const.
5835 2006-06-10 Andreas Schwab <schwab@suse.de> (tiny change)

5853 2006-05-06 Eric Blake <ebb9@byu.net>
5855 * po/Makevars (MSGID_BUGS_ADDRESS): Add.
5856 * po/POTFILES.in (src/getopt.c, src/version-etc.c): These files live
5857 in src, not gnu.
5859 2006-05-06 Eric Blake <ebb9@byu.net>
5861 * configure.ac (LT_CONFIG_LTDL_DIR): Inform libtool which
5862 subdirectory to use.
5863 (support for -pipe): Move after LT_INIT, since it relies on
5864 libtool internals.
5866 2006-05-05 Eric Blake <ebb9@byu.net>
5868 * Makefile.am (doc/m4.1): Use $@, not $(srcdir)/doc/$@.

5888 and 1.10.x support --cache=off, so $WGETFLAGS are not necessary.
5889 Reported by Eric Blake <ebb9@byu.net>
5891 2005-12-04 Gary V. Vaughan <gary@gnu.org>
5893 * bootstrap (func_update_po): Test and set $WGETFLAGS to disable
5894 http caching as -C is no longer supported by wget 1.10.x.
5895 Reported by Eric Blake <ebb9@byu.net>
5897 2005-10-20 Gary V. Vaughan <gary@gnu.org>
5899 * m4/module.c (caller_id): To match libtool-2.0 interface, changed
5900 to ...
5901 (iface_id): ...an lt_dlinterface_id type.
5902 (m4__module_find): New abstraction for lt_dlhandle_fetch. Use
5903 throughout, instead of calling obsolete lt_dlhandle_find directly.
5904 (m4__module_next): Use multiloader-safe lt_dlhandle_iterate. Use
5905 throughout, instead of calling obsolete lt_dlhandle_next.
5906 * m4/m4private.h (m4__module_find): Declare it.
5907 * m4/builtin.c (m4_builtin_find_by_name, m4_builtin_find_by_func):
5908 Use m4__module_next instead of obsolete lt_dlhandle_next.
5910 2005-10-20 Gary V. Vaughan <gary@gnu.org>
5912 * bootstrap (func_update_po): Update pofiles directly from the
5913 translation project.
5914 * po/LINGUAS, po/cs.po, po/de.po, po/el.po, po/fr.po, po/it.po,
5915 po/ja.po, po/nl.po, po/pl.po, po/ru.po, po/sv.po: No need to store
5916 these files under source control anymore.
5917 Suggested by Eric Blake <ebb9@byu.net>
5919 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
5921 * ltdl/m4/m4-gnulib.m4: Update FSF contact address. Somehow this
5922 file escaped the address updates on 2005-05-01.
5924 2005-07-07 Gary V. Vaughan <gary@gnu.org>
5926 * bootstrap: Allow user overriding of gnulib-tool location, and
5927 correctly determine module source directories whether gnulib-tool
5928 is given as a relative or absolute path, or is found by searching
5929 PATH.
5930 Reported by Eric Blake <ebb9@byu.net>
5932 2005-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5934 * ltdl/m4/debug.m4 (m4_CHECK_DEBUGGING): Make sure that both $rm
5935 and $RM are defined for various versions of
5936 AC_LIBTOOL_COMPILER_OPTION.
5938 * bootstrap (AUTORECONF): New variable to allow user overriding of
5939 autoreconf path.
5941 2005-07-07 Gary V. Vaughan <gary@gnu.org>
5943 * doc/m4.texinfo (History): Add better notes on the ancestory of
5944 GNU m4, and other historical interest.
5946 2005-05-08 Gary V. Vaughan <gary@gnu.org>
5948 * m4/symtab.c (m4_symbol_rename): New function that performs a low
5949 level symbol rename.
5950 * m4/m4module.h (m4_symbol_rename): Declare it as part of the API.
5951 * modules/gnu.c (regsub): Factored out of m4_epatsubst_do...
5952 (m4_patsubst_do, m4_renamesyms_do): ...wrappers that use
5953 regsub...
5954 (erenamesyms, renamesyms): ...builtins that use these to implement
5955 macro renaming by regular expression.
5956 * doc/m4.texinfo (Erenamesyms and Renamesyms): Document them.
5957 * tests/generate.awk: Allow some forbidden `m4_' prefixed symbols
5958 to stop the new generated tests from choking.
5960 2005-05-07 Gary V. Vaughan <gary@gnu.org>
5962 Since most of the build is handled from a single Makefile.am now,
5963 we can teach make about the dependencies between the m4 binary and
5964 the preopened modules it is built against:
5966 * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
5967 preopened modules.
5968 * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
5969 of the preopened modules have changed.
5971 2005-05-07 Gary V. Vaughan <gary@gnu.org>
5973 * configure.ac (gl_MODULES): Add mkstemp for machines that don't
5974 have a native implementation.
5976 2005-05-06 Gary V. Vaughan <gary@gnu.org>
5978 * src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are
5979 handled already by gnu/exit.h.
5981 * configure.ac (gl_MODULES): Add assert to support a
5982 --disable-assert configure time option for NDEBUG setting.
5984 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.
5985 * bootstrap (src_modules): Add version-etc-fsf.
5986 * src/main.c (version_etc_copyright): Removed.
5988 * ltdl/m4/m4-getopt.m4 (m4_GETOPT): Synch with gnulib/getopt.m4.
5990 2005-05-04 Gary V. Vaughan <gary@gnu.org>
5992 * src/m4.h (__CYGWIN__, WIN32): Canonicalise Windows and Cygwin
5993 recognition macros.
5994 * src/freeze.c (produce_frozen_state): Use \n line-endings even
5995 on Windows, so that the frozen file reader will work.
5996 Reported by Josef T. Burger <bolo@bolo.com>
5998 2005-05-04 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
6000 Forward port of a patch that allowed m4-1.4.2 to compile on
6001 QNX 6.3:
6003 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
6004 sys/signal.h.
6005 * src/m4.h: And include them as appropriate.
6006 * src/main.c, src/stackovf.h: Don't include signal.h literally;
6007 m4.h will include the correct file.
6009 2005-05-04 Gary V. Vaughan <gary@gnu.org>
6011 * m4/m4private.h: Make errno visible for the sources patched
6012 below.
6014 2005-05-04 Paul Eggert <eggert@twinsun.com>
6016 * src/main.c (print_program_name_CB): Preserve errno, since
6017 M4ERROR relies on this.
6018 * modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
6019 * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
6020 * m4/path.c (m4_path_search): Don't let "free" trash errno when
6021 returning NULL.
6023 * m4/output.c (m4_insert_file): Don't assume errno has a valid
6024 value simply because fread returns zero. This fixes a
6025 portability bug reported by Marion Hakanson in
6026 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
6028 2005-05-04 Santiago Vila <sanvila@debian.org>
6030 * tests/stackovf.test: Use tempfile if available.
6032 2005-05-04 Robert Bihlmeyer <robbe@orcus.priv.at> (tiny change)
6034 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=92629
6035 * m4/output.c (m4_insert_file): Do not mix buffered and
6036 unbuffered I/O, as this breaks on the Hurd.
6038 2005-05-04 Gary V. Vaughan <gary@gnu.org>
6040 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
6041 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
6042 and libtoolize does a better job of ltdl importing now too, so
6043 take advantage of that while updating the tree:
6045 * acm4, config: Moved from here...
6046 * ltdl/m4, ltdl/config: ...to here.
6047 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
6048 src/Makefile.am, tests/Makefile.am: Removed...
6049 * Makefile.am: ...and migrated to here, with adjustments to
6050 compensate for relative path differences.
6051 * commit: Adjust relative paths.
6052 * configure.ac: Adjust relative paths.
6053 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
6054 patch.
6055 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
6056 the meanwhile, CVS HEAD libtool is needed.
6057 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
6058 stricly new enough, we also need a patch.
6059 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
6060 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
6061 (gl_MODULES): Don't list getopt and version-etc, as they don't
6062 belong in libm4.
6063 * bootstrap: After running gnulib-tool to import the listed
6064 modules, fetch getopt and version-etc into src manually.
6065 (ltdldir): Change to ltdl.
6066 * src/main.c: Adjust for changes in version-etc API.
6067 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
6068 but works when the getopt module isn't to be included in the lib.
6069 * README: Add note about patching autoconf and automake to
6070 bootstrap CVS m4.
6072 2005-05-02 Matt Kraai <kraai@debian.org> (tiny change)
6074 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=84416
6075 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
6076 empty file rather than to a nonexistent file. This closes a
6077 common security hole.
6078 * modules/m4.c (m4_maketemp): Implement the above, by using
6079 mkstemp rather than mktemp.
6081 2005-05-01 Gary V. Vaughan <gary@gnu.org>
6083 The FSF are moving offices today. Changed their contact address
6084 in all files from `59 Temple Place, Suite 330, MA 02111-1307' to
6085 `51 Franklin Street, Fifth Floor, MA 02110-1301'.
6087 2005-03-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
6089 * tests/Makefile (clean-local): Ignore testsuite cleanup
6090 failures.
6092 2005-03-11 Per Bothner <per@bothner.com> (tiny change)
6094 * tests/Makefile (clean-local): Only run the testsuite cleanup
6095 if the testsuite has been generated.
6097 2005-02-11 Stepan Kasal <kasal@ucw.cz>
6099 * TODO: slight clarification of the example of qindir usage.
6101 2005-02-08 Gary V. Vaughan <gary@gnu.org>

6104 From Stepan Kasal <kasal@ucw.cz>
6106 2005-02-08 Stepan Kasal <kasal@ucw.cz>
6108 * TODO: Add ``execution stack'', fix a typo.
6109 * doc/m4.texinfo: Typos.
6111 2004-12-24 Eric Blake <ebb9@byu.net>
6113 * configure.ac (INCLUDE_STDBOOL_H): Account for gnulib's move
6114 to the gnu subdirectory.
6115 * acm4/m4-error.m4 (INCLUDE_ERROR_H): Likewise.
6116 * acm4/m4-obstack.m4 (INCLUDE_OBSTACK_H): Likewise.
6117 * acm4/m4-regex.m4 (INCLUDE_REGEX_H): Likewise.
6118 * m4/system_.h: Likewise, in non-configured includes.
6120 2004-10-14 Noah Misch <noah@cs.caltech.edu>,
6121 Gary V. Vaughan <gary@gnu.org>
6123 * m4/m4.c (m4_context_field_table, m4_context_opt_bit_table):
6124 Protect definitions from macro expansion under -DNDEBUG by
6125 parenthesising the expanded function names.
6126 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
6127 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
6128 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
6129 (m4_is_syntax_macro_escaped): Similarly protect function
6130 definitions from macro expansion under -DNDEBUG by #undefing the
6131 matching macro names before each definition. Also, move all the
6132 function definitions to the end of the file so that any
6133 invocations in the rest of the file pick up the fast macro
6134 versions.
6135 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)
6136 (m4_set_debug_file, m4_set_trace_messages)
6137 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
6138 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
6139 (m4_set_max_debug_arg_length_opt): New fast macro versions of the
6140 option setter functions.
6142 2004-09-23 Gary V. Vaughan <gary@gnu.org>
6144 * po/POTFILES.in: Reflect move of gnulib files from gnulib/m4
6145 to gnu.
6147 2004-09-23 Gary V. Vaughan <gary@gnu.org>
6149 * src/main.c: Include gnulib files from the correct directory.
6151 * gnulib/*: Don't store any of the gnulib files in arch, as they
6152 generate spurious changes.
6153 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
6154 gnulib macros now share our macro directory.
6155 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
6156 * bootstrap: Call gnulib-tool to import from the gnulib tree.
6157 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
6158 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
6159 the gettext macros from autopoint that overwrite the gnulib-tool
6160 imported versions. Import sources and Makefile.am into the `gnu'
6161 directory. Changed all callers.
6162 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
6163 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
6164 for imported modules.
6165 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
6166 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
6167 hardcoding the gnulib macros they wrap.
6169 2004-07-15 Gary V. Vaughan <gary@gnu.org>
6171 Latest CVS libtool can preload modules in libraries, including
6172 its own module loaders! Tweak m4 so that it doesn't try to treat
6173 libltdl's module loaders as m4 modules when freezing and on exit:
6175 * gnulib/acm4/*.m4: Don't store these files in arch since they
6176 generate spurious changes.
6177 * bootstrap: Simplify initial libtoolize call, since CVS
6178 libtoolize is smarter these days.
6179 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
6180 build.
6181 * m4/module.h (m4__module_exit): Missing declaration.
6182 * m4/m4private.h (m4__module_next): New function declaration.
6183 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
6184 encapsulation. Changed all callers.
6185 (m4__module_interface): New function to verify m4 loadable module
6186 interfaces.
6187 (m4__module_init): Register the interface validator.
6188 (m4__module_exit): Only close my own modules.
6189 * modules/m4.c (unistd.h): Provide missing declaration.
6190 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
6191 (m4_expand_ranges): More missing declarations.
6192 * modules/modtest.c (export_test): Ditto.
6193 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
6194 * src/main.c (main): Bump copyright year.
6195 * tests/modules.at: Fix sed syntax error.
6198 2004-06-17 Gary V. Vaughan <gary@gnu.org>
6200 Tweaking to enable compilation with latest CVS libtool and
6201 libltdl. We can't just dump the library files directly into the
6202 m4 directory anymore now that libltdl is built from pieces itself:
6204 * bootstrap: Rewritten to use latest libtoolize sanely, and to
6205 set up libltdl subdirectory.
6206 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
6207 gnulib subdirectory's config.
6208 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
6209 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
6210 macros from gnulib.
6211 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
6212 configure.ac, so use AC_WITH_LTDL instead.
6213 * Makefile.am (SUBDIRS): Add libltdl.
6214 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
6215 gl_INCLUDED_REGEX.
6216 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
6217 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
6218 (libm4_la_LIBADD): Add LIBLTDL.
6219 * m4/ltdl.c, m4/ltdl.h: Removed.
6220 * m4/m4module.h: Include canonical ltdl.h.
6221 * po/*.po: Updated.
6223 2004-06-14 Gary V. Vaughan <gary@gnu.org>
6225 * gnulib/import: Now updates makefile fragments, and configure.ac.
6226 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
6227 * gnulib/m4/Makefile.am: include it.
6228 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
6229 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
6230 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
6231 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
6232 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
6233 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,
6234 gnulib/acm4/lib-ld.m4, gnulib/acm4/lib-prefix.m4,
6235 gnulib/acm4/error.m4, gnulib/acm4/po.m4, gnulib/acm4/regex.m4,
6236 gnulib/acm4/stdbool.m4, gnulib/acm4/stdint_h.m4,
6237 gnulib/acm4/uintmax_t.m4, gnulib/acm4/ulonglong.m4,
6238 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
6239 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
6240 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
6241 import.
6242 * gnulib/m4/getopt_int.h: New source file from latest gnulib
6243 import.
6244 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
6245 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,
6246 gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
6247 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
6248 Updated source files from latest gnulib.
6250 2004-02-29 Gary V. Vaughan <gary@gnu.org>
6252 * config/mailnotify: New file for mailing commit notifications,
6253 imported from cvs-utils.
6254 * commit: Updated from cvs-utils and tweaked for m4.
6256 2003-12-01 Gary V. Vaughan <gary@gnu.org>
6258 * config/mkstamp: Updated from CVS libtool.
6259 * configure.ac: Generate a gnu coding standards compliant version
6260 number, and use it for the banner.
6261 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
6262 mhen the TIMESTAMP changes in ChangeLog, but the file modification
6263 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
6264 contain the previous version number.
6265 * src/main.c: Make --version output conform to the GNU standard.
6267 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
6268 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
6269 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
6270 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
6271 time_la_SOURCES): ...so that these are defaulted correctly, and
6272 can be removed from this file.
6273 (AM_LDFLAGS): Add -module...
6274 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
6275 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
6276 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
6277 the individual settings can be removed.
6278 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
6279 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
6280 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
6281 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
6282 time_la_LIBADD): ...so that these are picked up as a deplib of
6283 libm4 and don't need to be set explicitly.
6285 2003-11-18 Gary V. Vaughan <gary@gnu.org>
6287 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
6288 from the standard build. It is too fragile.
6290 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
6291 CVS libtool after merging m4 changes across to libtool.
6293 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
6294 * m4/path.c (search_path_add): Ditto.
6296 2003-11-13 Gary V. Vaughan <gary@gnu.org>
6298 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
6299 libtool tags we don't use in configure. This reduces the size
6300 of the script from over 1Mb to under 700Kb.
6302 2003-11-13 Gary V. Vaughan <gary@gnu.org>
6304 The import script was not written properly, and the last gnulib
6305 import was incomplete. Fixed that problem, and reimport our
6306 gnulib dependencies, which picks up the address calculation
6307 overflow checks described by Paul below. Also tweak the clients
6308 of the gnulib xalloc module not to use deprecated macros:
6310 * gnulib/import: Recurse through module dependencies rather than
6311 naively descending only one level.
6312 * configure.ac: Add calls to gnulib's strnlen and extension module
6313 macros.
6314 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and

6321 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
6322 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
6323 place of `xcalloc (1, S)'.
6324 * m4/m4.c (m4_create): Likewise.
6325 * m4/m4private.h (m4_symbol_value_create): Likewise.
6326 * m4/symtab.c (symtab_fetch): Likewise.
6327 * m4/syntax.c (m4_syntax_create): Likewise.
6328 * src/freeze.c (reload_frozen_state): Likewise.
6329 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
6330 macro.

6333 2003-11-13 Gary V. Vaughan <gary@gnu.org>
6335 * tests/module.at: Comment typo.
6337 2003-10-10 Gary V. Vaughan <gary@gnu.org>
6339 * tests/modules.at (modules: importing): Apply some lateral
6340 thinking, and use AT_CHECK to compare the output of a sed pass
6341 over stderr against the canonical strerror string.
6343 * tests/modules.at (modules: importing): Edit the generated stderr
6344 output to canonicalize strerror output, before a comparison.
6346 2003-10-10 Gary V. Vaughan <gary@gnu.org>
6348 Tru64UNIX perl is sloppy with namespace pollution. This patch is
6349 careful not to trip over the mess:
6351 * modules/perl.c: Some builds of perl install headers that contain
6352 `#define try __builtin_try'. Be sure to undefine that macro
6353 before `m4/hash.h' gets included, which uses the `try' symbol.
6354 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
6355 `false' before including `stdbool.h'.
6356 (DELETE): This symbol is not in m4's namespace, and is in any
6357 case only used internally...
6358 * m4/m4private.h (DELETE): ...so move it to here.

6363 Don't use XMALLOC and XCALLOC. Once we install the
6364 corresponding patch into gnulib, this will fix some
6365 address-calculation overflow bugs on hosts where calloc (A, B)
6366 returns garbage when A*B overflows.
6368 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
6369 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
6370 xmalloc, XCALLOC with xcalloc.
6371 * m4/m4.c (m4_create): Likewise.
6372 * m4/m4private.h (m4_symbol_value_create): Likewise.
6373 * m4/output.c (m4_output_init): Likewise.

6375 * m4/syntax.c (remove_syntax_attribute): Likewise.
6376 * src/freeze.c (reload_frozen_state): Likewise.
6377 * src/main.c (main): Likewise.
6379 2003-10-07 Gary V. Vaughan <gary@gnu.org>

6382 gnulib/acm4 directories for aclocal m4 macros.
6383 * gnulib/Makefile.am (EXTRA_DIST): Removed.

6386 modules we use.
6387 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
6388 * gnulib/import: New file. Temporary script for updating gnulib
6389 imported files, until gnulib-tool is working.

6435 gnulib/m4/xalloc.h, gnulib/m4/xmalloc.c: Updated from CVS
6436 gnulib with gnulib/import script.
6437 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
6438 guards ready for gnulib-tool to autoupdate on import.
6439 * config/debug.m4, config/gmp.m4, config/m4-error.m4,
6440 config/m4-gettext.m4, config/m4-obstack.m4, config/m4-regex.m4,
6441 config/stackovf.m4: Moved from here...
6442 * acm4/debug.m4, acm4/gmp.m4, acm4/m4-error.m4,
6443 acm4/m4-gettext.m4, acm4/m4-obstack.m4, acm4/m4-regex.m4,
6444 acm4/stackovf.m4: ...to here, to separate aclocal macros from
6445 configure time helper scripts.
6446 * config/error.m4: Removed; superceded by gnulib/acm4/error.m4.
6447 * m4/hash.c, m4/m4.c, m4/macro.c, m4/module.c, m4/output.c,
6448 m4/path.c, m4/symtab.c, m4/syntax, m4/system_.h, modules/m4.c,
6449 src/main.c, src/stackovf.c: s/xfree/free/g to comply with new
6450 gnulib xalloc.h.
6451 * src/main.c (version_etc_copyright): Only output the current
6452 year.
6453 (version_etc): Call with new variadic API.
6455 2003-09-16 Gary V. Vaughan <gary@gnu.org>
6457 * gnulib/m4/version-etc.c, gnulib/m4/version-etc.h: Import
6458 version-etc module from CVS gnulib.
6459 * po/POTFILES.in: Add gnulib/m4/version-etc.c.
6460 * src/Makefile.am: Build it.
6461 * src/main.c: Use it.
6463 * gnulib/m4/exit.h: Import exit module from CVS gnulib.
6464 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
6465 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
6466 exit.h instead.
6468 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
6469 Gary V. Vaughan <gary@gnu.org>
6471 * bootstrap: Separate options.
6472 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
6473 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
6474 not set.
6475 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
6476 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
6477 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
6478 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
6479 $(LTLIBINTL) for gettext support on cygwin.
6480 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
6481 have $(LTLIBINTL) from the preloaded module la files.
6482 * README: Remove the warning about using --disable-nls on Windows
6483 machines.
6485 2003-09-15 Gary V. Vaughan <gary@gnu.org>
6487 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
6488 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
6489 is required.
6491 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6493 * doc/STYLE: Document the gnulib header naming conventions, and
6494 #include policy.
6495 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
6496 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,
6497 gnulib/m4/gettext.h, gnulib/m4/obstack.h, gnulib/m4/regex.h
6498 respectively.
6499 * gnulib/m4/Makefile.am: Remove the rules to build these headers.
6501 * gnulib/m4/strtol.c, gnulib/config/strtol.m4: Import strtol
6502 module from CVS gnulib.
6503 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
6504 (gl_FUNC_STRTOL): In favour of the module macro.
6506 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6508 Replace the getopt code with CVS gnulib getopt. The source files
6509 detect whether they are in a glibc environment and preprocess away
6510 all of the code if there is a system getopt, so we can compile
6511 them into the m4 executable unconditionally:
6513 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
6514 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
6515 * configure.ac (gl_GETOPT): Use this instead of homebrew inline
6516 macros.
6517 * src/getopt.c, src/getopt1.c, src/gnu-getopt.h: Removed old
6518 version.
6519 * src/Makefile.am: Adjust.
6520 * src/main.c: Always include our shipped getopt.h.
6521 * po/POTFILES.in: Use new location of getopt.c.
6523 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6525 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
6526 * config/Makefile.am: Removed. Automake 1.8 distributes the files
6527 in this directory automatically.
6528 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
6530 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
6531 isn't set yet.
6532 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
6533 inline.
6534 * modules/Makefile.am (pkglibexecdir): Set it here.
6535 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
6537 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
6538 Import regex module from CVS gnulib.
6539 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
6540 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
6541 do extra substitutions for Makefile.
6542 * configure.ac: Use it.
6543 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
6544 from regex_.h if necessary.
6545 * m4/system_.h: Include the correct version of regex.h.
6546 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
6547 version.
6548 * po/POTFILES.in: Use new location of regex.c.
6550 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
6551 realloc.c: automake distributes these files already.
6553 2003-09-12 Gary V. Vaughan <gary@gnu.org>
6555 Replace the xstrzdup code by importing the xstrndup module from
6556 CVS gnulib, along with its dependencies: strndup and strnlen:
6558 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
6559 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
6560 gnulib.
6561 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
6562 gnulib/config/strndup.m4: Ditto wrt strndup.
6563 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
6564 strnlen.
6565 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
6566 However, contrary to gnulib, we install xstrndup.h.
6567 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
6568 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
6569 is an artifact of the old m4 portability layer.
6570 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
6571 * m4/system_.h: Include xstrndup.h.
6572 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
6574 2003-09-11 Gary V. Vaughan <gary@gnu.org>
6576 Reimport the latest xalloc module from CVS gnulib, and adjust the
6577 m4 sources to take advantage of xalloc xfree. Also create a new
6578 macro DELETE with the same semantics as the old m4 XFREE macro,
6579 and carefully tweak callers:
6581 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
6582 gnulib.
6583 * m4/utility.c (xfree): Removed. This function is now supplied by
6584 gnulib xalloc.
6585 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
6586 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
6587 * m4/symtab.c (m4_symtab_create): Ditto.
6588 * m4/system_.h: Removed XFREE redefine.
6589 (DELETE): New macro with same functionality as the original m4
6590 XFREE macro, but based on xalloc.h now. Changed all callers.
6591 * src/main.c (main): Use XMALLOC macro.
6592 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
6593 instead of XFREE.
6594 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
6596 2003-09-10 Gary V. Vaughan <gary@gnu.org>
6598 Import the xalloc module from CVS gnulib, along with its
6599 dependencies: exitfail, malloc and realloc. We had different
6600 semantics for our XFREE and a function xfree() not supplied by
6601 gnulib, so also a bit of work to keep everything running
6602 smoothly:
6604 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
6605 (gl_XALLOC): Use gnulib equivalents.
6606 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
6607 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
6608 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
6609 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
6610 realloc.
6611 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
6612 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
6613 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
6614 imported modules.
6615 (pkgincdir): Removed. Use pkgincludedir instead.
6616 * m4/m4private.h (XFREE): xfree already checks for NULL.
6617 * m4/system_.h: Use xalloc module, and remove macros already
6618 supplied by xalloc.h.
6619 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
6620 moved the old definition from m4/xmalloc.c to here for now.
6622 2003-09-09 Gary V. Vaughan <gary@gnu.org>
6624 Import the error and progname modules from CVS gnulib. Our old
6625 error.c subsumed the functionality of both, so a little adjustment
6626 was required to accomodate the split in sources. Also added more
6627 wrapper macros to choose between a system installed error.h or our
6628 shipped gnulib error module:
6630 * m4/error.c, m4/error.h: Removed.
6631 * m4/Makefile.am: Adjust.
6632 (pkgincdir): Removed. Use pkgincludedir instead.
6633 * m4/module.h, src/main.c: Don't include `m4/error.h'.
6634 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
6635 error.h.
6636 * gnulib/m4/progname.c: Imported from CVS gnulib.
6637 * gnulib/m4/progname.h: Ditto.
6638 * src/main.c: Adjust to use progname module.
6639 * gnulib/m4/error.c: Imported from CVS gnulib.
6640 * gnulib/m4/error_.h: Ditto.
6641 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
6642 if appropriate, and link a local error.h if the system version is
6643 missing.
6644 (libgnu_la_SOURCES) Add progname module sources.
6645 * gnulib/config/error.m4: Imported from CVS gnulib.
6646 * gnulib/config/strerror_r.m4: Ditto.
6647 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
6648 to have ERROR_H for Makefile substitutions and tell system.h
6649 whether the system error.h should be used, or a locally installed
6650 version.
6651 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
6653 2003-09-09 Gary V. Vaughan <gary@gnu.org>
6655 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
6656 s/gettext_.h/gettext.h/.
6658 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
6659 automake have been fixed.
6661 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
6662 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
6663 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
6664 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
6666 2003-09-09 Gary V. Vaughan <gary@gnu.org>
6668 The gnulib obstack module requires the gnulib gettext module for
6669 systems that do not have GNU gettext installed. Because we use
6670 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
6671 that directory incase it clashes with the system gettext.h. This
6672 delta uses gettext_.h and extra rules in the Makefile to make a
6673 link to gettext.h when needed:
6675 * Makefile.am (auxdir): Removed. No longer used.
6676 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
6677 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
6678 moved.
6679 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
6680 Makefile based build.
6681 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
6682 of the macros are kept.
6683 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
6684 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
6685 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
6686 distributes these automatically.
6687 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
6688 warning from automake-1.7a.
6689 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
6690 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
6691 all callers.
6692 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
6693 wrt. m4_FUNC_OBSTACK.
6694 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
6695 wrt. m4_sys_STACKOVF.
6696 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
6697 wrt. _m4_LIB_GMP, m4_LIB_GMP.
6698 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
6699 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
6700 respectively.
6701 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
6702 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
6703 gettext.h link on deficient systems.
6704 (pkginc_HEADERS): Mention $(GETTEXT_H).
6705 (EXTRA_HEADERS): Mention gettext.h.
6706 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
6707 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
6708 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
6709 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,

6715 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
6716 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
6718 2003-09-05 Gary V. Vaughan <gary@gnu.org>
6720 We can't mirror the gnulib directory structure here, since we need
6721 to be able to eg. `#include <m4/obstack.h>' from our source files,
6722 which is much easier if the local obstack.h is created in a
6723 directory named m4. Rather than trying to symlink everything into
6724 the m4 directory, now we build a libtool convenience library from
6725 the sources we get from gnulib and link that with libm4.la:
6727 * gnulib/config/extensions.m4: Imported from CVS gnulib.
6728 * gnulib/config/unlocked-io.m4: Ditto.
6729 * gnulib/m4/unlocked-io.h: Ditto.
6730 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
6731 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
6732 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
6733 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
6734 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
6735 * m4/Makefile.am: Adjust.
6736 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
6737 macros we redistribute.
6738 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
6739 library among others.
6740 (GNULIB_SRCS, GNULIB_MACROS): Removed.
6741 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
6742 * config/m4-obstack.m4: Adjust.
6743 * po/POTFILES.in: Adjust.
6744 * configure.ac: Reformatting. Call newly imported gnulib macros.
6745 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
6746 bogus calls of `#include "m4.h"'.
6747 * Makefile.am: INCLUDES has been deprecated in favour of
6748 AM_CPPFLAGS.
6749 * m4/Makefile.am: Ditto.
6750 * modules/Makefile.am: Ditto.
6751 * src/Makefile.am: Ditto.
6753 2003-09-05 Gary V. Vaughan <gary@gnu.org>
6755 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
6757 2003-09-04 Gary V. Vaughan <gary@gnu.org>
6759 Migrate the obstack support into the gnulib directories for easy
6760 synchronisation with upstream files in gnulib:
6762 * config/gnu-obstack.m4: Moved from here...
6763 * config/m4-obstack.m4: ...to here.
6764 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
6765 * m4/obstack.c, m4/obstack_.h: Moved from here...
6766 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
6767 * po/POTFILES.in: Adjust.
6768 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
6769 * m4/Makefile.am: Add a whole new section to link the obstack
6770 sources from the gnulib tree if necessary.
6771 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
6772 from gnulib.
6773 * config/m4-obstack.m4: Rewrite as a wrapper for
6774 gnulib/m4/obstack.m4.
6776 2003-09-04 Gary V. Vaughan <gary@gnu.org>
6778 GNU M4 currently builds with a number of files adapted from
6779 upstream sources. Recently the gnulib project on savannah.gnu.org
6780 has pulled together a great many of these externally maintained
6781 files. This delta is the beginnings of isolating those files
6782 maintained in gnulib to make it easy to synchronise M4 with the
6783 upstream files prior to releases.
6785 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
6786 directory.
6787 (SUBDIRS): Added new gnulib subdirectory.
6788 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
6789 * config/stdbool.m4: Moved from here...
6790 * gnulib/m4/stdbool.m4: ...to here.
6791 * m4/stdbool_.h: Moved from here...
6792 * gnulib/lib/stdbool_.h: ...to here.
6793 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
6794 distributed.
6795 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
6796 code to work with new stdbool_.h location.
6797 (gnulib_srcdir): New.
6799 2003-09-04 Gary V. Vaughan <gary@gnu.org>
6801 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
6802 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
6803 builds to work.
6804 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
6805 (EXTRA_DIST): Use it.
6807 * bootstrap: CVS autoreconf leaves file droppings. Remove
6808 aclocal.m4t incase autoreconf doesn't.
6810 2003-08-29 Gary V. Vaughan <gary@gnu.org>
6812 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
6813 the other gnulib imports, renamed to m4/obstack_.h.
6814 * m4/obstack.c: Updated from CVS gnulib.
6815 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
6816 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
6817 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
6818 about vpath already, and $top_srcdir upsets CVS Automake, so the
6819 $top_srcdir reference was removed.
6821 * m4/system-h.in: For consistency with the gnulib imports, renamed
6822 to m4/system_.h.
6823 * m4/Makefile (EXTRA_HEADERS): Adjust.
6824 * configure.ac (AC_CONFIG_FILES): Adjust.
6826 * m4/stdbool_.h: New file from gnulib for systems without their
6827 own.
6828 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
6829 * config/stdbool.m4: New file. Macros from gnulib for same.
6830 * configure.ac: Use it.
6832 2003-08-27 Gary V. Vaughan <gary@gnu.org>
6834 * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'`

6881 * src/main.c: Ditto.
6882 * src/stackovf.c: Ditto.
6884 * config/gmp.m4 (M4_AC_LIB_GMP): Use AC_INCLUDES_DEFAULT:
6885 ac_default_headers is an autoconf internal variable.
6886 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
6887 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
6889 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
6890 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
6891 delta.
6893 2003-08-15 Gary V. Vaughan <gary@gnu.org>
6895 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
6896 C99 bool.
6897 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
6898 possible or faking one with a typedef. Changed all callers.
6900 2003-08-15 Gary V. Vaughan <gary@gnu.org>
6902 Still cleaning up the users' module API, by taking out the stuff
6903 that isn't used by any existing modules, and moving specialised
6904 functions out of libm4 and into the module they are used by.
6906 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
6907 * m4/utility.c (m4_skip_space): ...to here the home of its only
6908 use, made static and renamed to `skip_space'. Changed all
6909 callers.
6910 * m4/m4module.h (m4_expand_ranges): Removed prototype.
6911 * m4/utility.c (m4_expand_ranges): Moved definition from here...
6912 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
6913 ltdl.
6914 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
6915 casting .
6916 * modules/gnu.c (builtin_syntax): Import and use in this
6917 builtin implementation.
6918 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
6919 Not used. Deleted.
6920 * m4/macro.c (trace_flush): Except here where the macro is now
6921 manually inlined.
6922 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
6923 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
6924 moved...
6925 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
6926 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
6928 2003-08-14 Gary V. Vaughan <gary@gnu.org>
6930 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
6931 compiler based AC_CHECK_HEADER that was introduced in
6932 autoconf-2.56.
6933 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
6934 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
6935 * configure.ac: Use renamed M4_AC_LIB_GMP.
6937 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
6938 macro that requires arguments! This stops the shell's bad
6939 substitution error at configure time.
6941 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
6942 variables to the testsuite shell. Set the value of USE_GMP so
6943 that the gmp test will run!
6944 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
6946 2003-08-11 Gary V. Vaughan <gary@gnu.org>
6948 Libltdl already has an excellent mechanism for accessing C symbols
6949 in modules. Lets use that! Remove all the exporting cruft and
6950 just use lt_dlsym in conjunction with a few conventions to
6951 simplify module writers' jobs. Also removed the table address
6952 caching code and otherwise simplified the module loader quite a
6953 bit. To access exported symbols in other modules, first the
6954 exporting module must name the symbols <modname>_LTX_<symname>,
6955 and the importing module must define a function type called
6956 <symname>_func. The importer then adds
6957 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
6958 that wishes to call out to the exported functions. Care must be
6959 taken that <symname> is non-NULL in the importing module incase
6960 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
6961 definition was in the importers source. Study
6962 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
6963 m4_module_import will attempt to automatically load a module
6964 required for symbol access if it is not loaded already.
6966 * TODO: Removed the items fixed in this delta.
6967 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
6968 module name.
6969 * m4/ltdl.h (lt_dlhandle_find): Declare it.
6970 * m4/module.c (m4_module_unload): Use it.
6971 * src/freeze.c (reload_frozen_state): Ditto.
6972 * m4/m4module.h (m4_export): Deleted. Removed all references.
6973 (M4_MODULE_IMPORT): New user convenience macro for importing
6974 arbitrary symbols from other modules.
6975 * m4/module.c (m4_module_import): New function to service
6976 M4_MODULE_IMPORT macro.
6977 (module_data): Removed. Looking up the tables on demand with
6978 lt_dlsym, rather than caching their addresses here simplifies the
6979 code substantially.
6980 (m4_get_module_builtin_table, m4_get_module_macro_table):
6981 Removed. Changed all callers.
6982 (set_module_macro_table, set_module_builtin_table): Renamed to
6983 install_macro_table and install_builtin_table respectively, and
6984 simplified now that the cache is no more.
6985 * modules/gnu.c (builtin_symbols): Use this new mechanism to
6986 import m4_dump_symbols from the m4 module.
6987 (builtin_esyscmd): Likewise for m4_set_sysval and
6988 m4_sysval_flush.
6989 * modules/m4.c (m4_export_table): Removed. Functions are
6990 addressed with the new mechanism which doesn't need this.
6991 (m4_set_sysval): New exported accessor function to prevent
6992 problems with variable access on inferior architectures.
6993 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
6994 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
6995 that we can have some type safety.
6996 * modules/modtest.c (export_test): C level exported function for
6997 testing the new import mechanism.
6998 * modules/import.c: New file for the import end of the test.
6999 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
7000 * tests/modules.at: New test cases for intermodule symbol
7001 importing.
7003 2003-08-07 Gary V. Vaughan <gary@gnu.org>
7005 * m4/m4module.c (m4_string): Moved from here...
7006 * m4/m4private.c (m4_string): ...to here.
7008 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
7010 2003-07-29 Gary V. Vaughan <gary@gnu.org>
7012 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
7013 already available to module writers through
7014 m4_{get,set}_nesting_limit_opt(), so moved from here...
7015 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
7016 (m4_create): Use it.
7018 2003-07-28 Gary V. Vaughan <gary@gnu.org>
7020 Aside from auditing path.c for m4module.h api obfuscation, this
7021 delta introduces the concept of private struct members in opaque
7022 data types to GNU m4: See the STYLE file for details.
7024 * TODO: Remind ourselves that a rewrite of path.c is needed.
7025 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
7026 Moved from here...
7027 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
7028 here and renamed. These type definitions are for internal api use
7029 only. Changed all callers.
7030 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
7031 Moved from here...
7032 * m4/path.c (search_path_env_init, search_path_add): ...to here
7033 and renamed. These calls were never used outside this file.
7034 Changed all callers.
7035 (dirpath): Moved functionality of this static declaration...
7036 * m4/m4private.h (struct m4): ...to this new internal only
7037 search_path field. Changed all callers.
7038 (m4__get_search_path): Added new internal api accessor.
7039 * m4/path.c (m4_search_path_info_new): Removed. Not used.
7040 (m4_include_init): Removed...
7041 * m4/m4.c (m4_create): ...because the new m4 field is now
7042 initialised here.
7043 (m4_delete): Recycle search_path memory.
7044 * src/main.c (main): Don't call m4_include_init now that it's
7045 gone!
7046 * doc/STYLE: Document convention for private fields in opaque
7047 ADTs.
7049 2003-07-24 Gary V. Vaughan <gary@gnu.org>
7051 Sometimes exporting the address of a symbol from a module isn't
7052 enough for other modules to call that symbol correctly. If
7053 custom data types are used for function parameters, they need to
7054 be known to the caller. This change introduces the concept of
7055 $(prefix)/include/modules/$(modulename).h to declare those
7056 structures. Also we move m4_dump_symbols from libm4 to the m4
7057 module to show this concept in action.
7059 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
7060 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
7061 exporting data structures from modules/m4.c.
7062 * modules/m4.c, modules/gnu.c: Include it.
7063 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
7064 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
7065 prototypes.
7066 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
7067 Moved from here...
7068 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
7069 ...to here, with slight renaming.
7070 (m4_export_table): Prototype and add m4_dump_symbols.
7071 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
7072 definition of m4_dump_symbols.
7073 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
7074 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
7076 2003-07-24 Gary V. Vaughan <gary@gnu.org>
7078 Create an export table in modules/m4.c in readiness for beefing up
7079 the module loader to track module exports and imports.
7081 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
7082 * m4/debug.c (m4_debug_flush_files): Moved...
7083 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
7084 * modules/gnu.c (builtin_esysval): Use it.
7085 * m4/m4module.h (m4_export): New type for declaring module symbols
7086 for export.
7087 * modules/m4.c (m4_export_table): List symbols exported from this
7088 module for use by other modules.
7090 2003-07-24 Gary V. Vaughan <gary@gnu.org>
7092 An experiment: There is loads of code in libm4 which should be in
7093 the m4 module, but is also used by another module. Just because
7094 some linkers won't cope with calls across dynamic runtime loaded
7095 objects I initially left the code in libm4. It will tidy the
7096 module api immensely if this code moves to the right place, I just
7097 need to remember to invent a suitable calling mechanism at some
7098 point. For now, only modules that are statically linked and
7099 preloaded will get this treatment, so the only platforms that will
7100 break are those that require all symbols to be resolved at link
7101 time.
7103 * TODO: Reminder that what I am doing could reduce portability
7104 unless I do something more robust later.
7105 * m4/m4module.h (m4_sysval): No longer exported from libm4.
7106 * m4/utility.c (m4_sysval): No longer declared in libm4.
7107 * modules/Makefile.am: Reformatting.
7108 * modules/m4.c (m4_sysval): Declare it at place of use.
7109 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
7111 2003-07-23 Gary V. Vaughan <gary@gnu.org>
7113 * m4/m4module.h: Reformatting and rearranging lines a bit.
7114 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
7115 all users.
7116 (m4_call_macro, m4_expand_input): Renamed...
7117 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
7118 callers.
7119 (m4_expansion_level, m4_process_macro): Moved...
7120 * m4/macro.c (expansion_level, process_macro): ...to here, and
7121 made static.
7123 * m4/m4module.h (program_name): Not used by modules at all, so
7124 moved...
7125 * src/main.c (program_name): ...to here.
7126 (print_program_name): Renamed...
7127 (print_program_name_CB): ...to conform to the STYLE guide.
7129 2003-07-23 Gary V. Vaughan <gary@gnu.org>
7131 More refactoring of the m4module.h API. Replace #defines with an
7132 enum, and move non-public functions out of the public API.
7134 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
7135 inclusion.
7136 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
7137 * m4/debug.c (m4_debug, trace): Moved...
7138 * m4/m4private.h (struct m4): ...to fields of this struct.
7139 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
7140 for the new fields.
7141 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
7142 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...

7144 * m4/m4module.h (m4_context_field_table): Add entries for new
7145 debug_file and trace_messages fields.
7146 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
7147 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
7148 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
7149 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
7150 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
7151 (m4_is_debug_bit): New macro to simplfy checks against the debug
7152 bits above.
7153 (m4_trace_format, m4_trace_header, m4_trace_flush)
7154 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
7155 prototypes.
7156 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
7157 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
7158 * m4/macro.c (trace_format, trace_header, trace_flush)
7159 (trace_prepre, trace_pre, trace_post): ...to these newly static
7160 functions, since they are only ever used from this file. Changed
7161 all callers.
7163 2003-07-17 Gary V. Vaughan <gary@gnu.org>
7165 Change the macros for checking syntax so that matching against
7166 multiple possible syntax classes can be done with a single
7167 comparison some of the time. The various classes are now bits of
7168 an int that can be checked with bitwise logic operators.
7170 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
7171 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
7172 (M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)
7173 (M4_SYNTAX_ASSIGN, M4_SYNTAX_ALPHA, M4_SYNTAX_NUM)
7174 (M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)
7175 (M4_SYNTAX_ECOMM): Replaced #defines with an enum.
7176 (M4_SYNTAX_ALNUM): Removed. Changed all callers.
7177 (M4_IS_IGNORE, M4_IS_OTHER, M4_IS_SPACE, M4_IS_OPEN, M4_IS_CLOSE)
7178 (M4_IS_COMMA, M4_IS_DOLLAR, M4_IS_ACTIVE, M4_IS_ESCAPE)
7179 (M4_IS_ASSIGN, M4_IS_ALPHA, M4_IS_NUM, M4_IS_LQUOTE, M4_IS_RQUOTE)
7180 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
7181 Replace all calls with invocations of these...
7182 (m4_is_syntax, m4_has_syntax): ...New macros.
7183 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
7184 is no longer required with new macros. Changed all callers.
7186 2003-07-15 Gary V. Vaughan <gary@gnu.org>
7188 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
7189 values are returned as part of the internal interface, so they
7190 need to be moved...
7191 * m4/private.h: ...to here.
7192 * m4/macro.c (expand_token): Check for out of range
7193 m4_peek_input() results before looking up in the syntax table.
7194 (collect_arguments): Ditto.
7196 * NEWS: Note `$' syntax class.
7198 2003-07-08 Paul Eggert <eggert@twinsun.com> and
7199 Gary V. Vaughan <gary@gnu.org>
7201 Conform to POSIX if the POSIXLY_CORRECT environment is set.
7202 --traditional `define' now smashes all the definitions.
7204 * NEWS: Explain this.
7205 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
7206 (Extensions): Explain that extensions that are incompatible with
7207 POSIX are disabled if POSIXLY_CORRECT is set.
7208 (Incompatibilities): Remove.
7209 (Define, Other Incompat): Explain difference
7210 between GNU and POSIX behavior of define, pushdef, popdef.
7211 * m4/m4.c (m4_get_posixly_correct_opt): New undef.
7212 * m4/m4module.h (m4_context_opt_bit_table): Add POSIXLY_CORRECT entry.
7213 * m4/m4private.h (M4_OPT_POSIXLY_CORRECT_BIT): New macro.
7214 (m4_get_posixly_correct_opt): New macro.
7215 * m4/m4macro.c (m4_process_macro): Disable $10, $abc etc. if
7216 POSIXLY_CORRECT.
7217 * modules/m4.c (builtin_functions): defn now takes any number of args.
7218 (builtin_define): Smash all the definitions if
7219 POSIXLY_CORRECT.

7221 (builtin_undivert): Do not allow nonnumeric arguments
7222 if POSIXLY_CORRECT.
7223 * src/main.c (main): Set posixly-correct behavior if either
7224 POSIXLY_CORRECT is set, or if -G is given.
7225 * tests/builtins.at: New test for smashed definitions.
7227 2003-06-27 Gary V. Vaughan <gary@gnu.org>
7229 * doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
7230 * m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
7231 not to slow the parser down.
7232 (M4__IS_STRING): New macro to test string syntax class membership.
7233 * m4/syntax.c: Adjust docucomment.
7234 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
7235 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
7236 * m4/input.c (init_builtin_token): Comment typo.
7237 (m4__next_token): Comment typo.
7238 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
7239 by using the new M4__IS_STRING macro.
7240 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
7241 variable references in macro expansions.
7243 * doc/m4.texinfo (Eregexp and Regexp): Typo.
7244 (Epatsubst and Patsubst): Typo.
7245 (Eval): Typo.
7247 2003-06-26 Gary V. Vaughan <gary@gnu.org>
7249 Move the global variables that pertain to syntax to a new `struct
7250 m4_syntax_table', and then add one of these to `struct m4'. The
7251 ripple effect through the code to both change formerly global
7252 references, and make sure a suitable context is available in
7253 lexical scope is disproportionately large compared to the size of
7254 the change proper. This change is a large part of decoupling
7255 syntax.c from the rest of the code that uses it.
7257 * m4/m4private.h (struct m4): Add a syntax field.
7258 * m4/m4.c (m4_create): Initialise it,
7259 (m4_delete): Recycle it.
7260 (m4_get_symtab): Remove hand coded version...
7261 (m4_get_symbol_table): ...and generate this with cpp. Changed all
7262 callers.
7263 * m4/m4module.h (m4_context_field_table): Add an extra field so we
7264 can generate m4_get_symbol_table. Add a new row for
7265 m4_get_syntax_table.
7266 (M4SYNTAX): Syntactic sugar for module writers.
7267 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
7268 (m4_syntax_table): New home for syntax related formerly global
7269 variables.
7270 * m4/m4private.h (struct m4_syntax_table): Define it.
7271 * m4/input.c (m4_input_init): Initialisation of these formerly
7272 global variables moved...
7273 * m4/syntax.c (m4_syntax_create): ...to here.
7274 * m4/input.c (m4_input_exit): And similarly, recycling of the
7275 memory used by those values moved...
7276 * m4/syntax.c (m4_syntax_delete): ...to here.
7277 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
7278 Moved to m4/m4private.h.
7279 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
7280 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
7281 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
7282 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
7283 objects. Changed all callers that used to directly access the
7284 global equivalents.
7285 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
7286 Removed and incorporated into m4_syntax_table structure.
7287 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
7288 * m4/syntax.c (m4_set_syntax): Now returns an error status,
7289 instead of requiring a `struct m4' to generate its own errors.
7290 Changed all callers.
7291 * src/main.c (main): Now that the syntax table is initialised as
7292 part of m4_create, we have to manually wipe the syntax entries if
7293 we are about to read a frozen file.
7295 2003-06-26 Gary V. Vaughan <gary@gnu.org>
7297 * doc/STYLE: Added notes on callback naming schemes.
7299 * m4/module.c (m4_set_module_macro_table)
7300 (m4_set_module_builtin_table): Declarations weren't changed when
7301 definitions were renamed on 2003-06-19.
7303 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
7304 neither used nor particularly appropriate since it exposes the
7305 internal workings of the hash module. I haven't yet decided
7306 whether to remove it entirely.
7308 2003-06-20 Gary V. Vaughan <gary@gnu.org>
7310 Two related changes, and a huge knockon effect throughout the
7311 source: Moved the option variables out of global space and into
7312 `struct m4'; made `m4_symtab' a real datatype, so that its api
7313 is not marred passing `struct m4' around just so it can decide
7314 whether to keep traced symbol names or not. Added setters and
7315 getters for the formerly global option variables, and obviously
7316 changed a vast number of functions to take a `struct m4' and use
7317 the getter funcs to find option values.
7319 * m4/utility.c (interactive, sync_output, debug_level)
7320 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
7321 (max_debug_argument_length, warning_status, nesting_limit)
7322 (discard_comments): Removed.
7323 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
7324 (debug_level, max_debug_argument_length, prefix_all_builtins)
7325 (suppress_warnings, discard_comments, interactive, sync_output):
7326 Removed from here...
7327 * m4/m4private.h (struct m4): ...and equivalent fields added to
7328 this structure.
7329 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
7330 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
7331 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
7332 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
7333 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
7334 macros for the new fields.
7335 * m4/m4module.h (m4_context_field_table)
7336 (m4_context_opt_bit_table): Helper macros used to generate
7337 prototypes, setters and getters for new option fields
7338 consistently.
7339 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
7340 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
7341 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
7342 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
7343 (m4_get_interactive_opt, m4_get_sync_output_opt)
7344 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
7345 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
7346 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
7347 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
7348 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
7349 setter and getter functions generated by cpp from
7350 m4_context_field_table and m4_context_opt_bit_table, exported as
7351 part of the module api. Changed all callers.
7352 * m4/symtab (struct m4_symtab): Used as the concrete type for
7353 m4_symtab now.
7354 (m4_symtab_create): Allocate and initialise a new struct.
7355 (m4_symtab_apply): New function that works like m4_hash_apply, but
7356 with different callbacks specific to symbol tables. Changed all
7357 callers.
7358 (symbol_destroy, arg_destroy, arg_copy): Renamed
7359 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
7360 they have unused parameters for a reason!
7361 (dump_symbol_CB): New callback to dump the contents of a single
7362 symbol.
7363 (symtob_dump): Rewritten in terms of dump_symbol_CB.
7364 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
7365 Changed all callers.
7366 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
7367 of the contained `m4_symtab' at the `no_gnu_extensions' field.
7368 Although I'm not convinced these semantics are correct, they are
7369 at least consistent with how things were before this delta. Also
7370 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
7372 2003-06-19 Gary V. Vaughan <gary@gnu.org>
7374 Tie down the interface to libm4 some more. Make more structures
7375 opaque to modules by moving them to m4private.h, and writing
7376 setters and getters. To win back the speed penalty for doing this
7377 also wrote macroized versions that do know about structure layout
7378 in m4private.h and #include that file into modules when NDEBUG is
7379 defined at compile time. There are still some accessor macros in
7380 m4private.h that need to go, but that is not necessary to clean
7381 the module api up.
7383 * m4/m4module.h (m4_symbol_type): Moved...
7384 * m4/m4private.h (m4__symbol_type): ...to here.
7385 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
7386 (m4_set_symbol_traced, m4_set_symbol_name_traced)
7387 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
7388 (m4_get_symbol_func, m4_symbol_value_create)
7389 (m4_symbol_value_delete, m4_set_symbol_value_text)
7390 (m4_set_symbol_value_func): New exported api to symbols.
7391 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
7392 and m4_is_symbol_value_func.
7393 * m4/m4module.h: Prototype these guys.
7394 * m4/module.c (m4_set_module_macro_table)
7395 (m4_set_module_builtin_table): Make these static, there is no
7396 reason to pollute the api with them.
7397 * m4/m4private.h: Reformatting.
7398 (m4_get_symtab): Only define when NDEBUG is defined.
7399 (m4_get_symbol_value, m4_get_symbol_traced)
7400 (m4_set_symbol_traced, m4_set_symbol_name_traced)
7401 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
7402 (m4_get_symbol_func, m4_symbol_value_create)
7403 (m4_symbol_value_delete, m4_set_symbol_value_text)
7404 (m4_set_symbol_value_func): Macro implementations of the new
7405 functions when NDEBUG is defined.
7406 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
7407 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
7408 Superceded by the above. All callers changed.
7409 (M4ARG): Removed. This is no longer different to the
7410 m4/m4module.h definition.
7411 * modules/gnu.c, modules/m4.c: Only include m4private.h when
7412 NDEBUG is defined. That way we exercise the same (albeit slower)
7413 api that external modules must use.
7415 2003-06-18 Gary V. Vaughan <gary@gnu.org>
7417 Renamed some of the types and their accessors to make more sense.
7418 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
7419 has a stack of SYMBOL_VALUEs.
7421 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
7422 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
7423 m4_get_symbol_value_type, m4_get_symbol_value_text,
7424 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
7425 Changed all callers.
7426 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
7427 (m4_get_token_type): Renamed
7428 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
7429 to the internal api.
7430 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
7431 s/TOKEN_/VALUE_/
7432 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
7433 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
7434 (m4__token_type): Moved here from m4module.h.
7435 (m4__next_token): Renamed from m4_next_token.
7436 * m4/symtab.c: Removed some of the parameterised macro support
7437 functions for modularisation later.
7438 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
7439 m4_hash_dup to perform a true deep copy of the SRC.
7440 (arg_copy): Callback for m4_symbol_value_copy.
7441 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
7442 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
7443 m4_get_symbol_value_func. Changed all callers.
7445 2003-06-18 Gary V. Vaughan <gary@gnu.org>
7447 Tidy up style of hash.[ch] in accordance with doc/STYLE.
7449 * m4/hash.c: Internal symbol renaming and formatting.
7450 (m4_hash_dup): New function to facilitate deep copies of hash
7451 tables.
7452 (m4_hash_apply_func): Returns a void* now, which is a richer type
7453 for returning exceptions (NULL means keep going).
7454 (m4_hash_apply): Ditto.
7455 * m4/hash.h: Declare exported symbols with an explicit extern.
7456 Reformated.
7458 2003-06-17 Gary V. Vaughan <gary@gnu.org>
7460 Still refactoring furiously. This delta represents a change in
7461 semantics to symtab.c. Instead of building temporary m4_tokens
7462 in the caller, and copying fields in the methods, we now create
7463 the actual m4_token for hashing in the caller so the methods just
7464 slot them in directly. Also, this means that we don't lookup a
7465 symbol and get back an allocated but VOID token to copy fields
7466 into, we create the token we want to push and pass that to
7467 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
7468 a few other small changes to stop knowledge of the implementation
7469 of symtab.c leaking out into other files.
7471 * m4/macro.c (expand_argument): Comment typo corrected.
7472 * m4/symtab.c (symtab_fetch): New function to fetch the address of
7473 an interned symbol.
7474 (m4_symbol_pushdef): Take an extra value parameter and use this
7475 directly as the new top of the value stack. All callers changed
7476 to build a token and pass responsibility for memory in, rather
7477 than copying as we used to.
7478 (m4_symbol_define): Also use the new value parameter directly as a
7479 replacement for the top of the value stack. All callers changed
7480 to build a token as above.
7481 (m4_set_symbol_traced): New function to set the traced bit on the
7482 named symbol, creating it if necessary.
7483 (symbol_popval): The guts of the old m4_symbol_popdef.
7484 (m4_symbol_popdef): Use it.
7485 * m4/builtin.c (m4_symbol_set_token): Removed,
7486 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
7487 replaced...
7488 * m4/module.c (m4_set_module_builtin_table)
7489 (m4_set_module_macro_table): ...with these more orthogonal
7490 functions.
7491 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
7492 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
7493 required.
7494 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
7495 (m4_arg_signature_parse): Moved...
7496 * m4/symtab.c: ...to here.
7497 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
7498 screw something up. Moved...
7499 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
7500 actually does a proper deep copy of source to dest.
7502 2003-06-16 Gary V. Vaughan <gary@gnu.org>
7504 Further refactoring to stabilise the module API. Renaming some
7505 functions for orthogonality, and judicious definition migration to
7506 move things out of the set of exported symbols.
7508 * doc/STYLE: New file. Notes on coding style.
7509 * m4/m4module.c: Updated bitrotted docucomment at the top of the
7510 file.
7511 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
7512 m4_get_module_name, m4_get_module_builtin_table,
7513 m4_get_module_macro_table which are verb phrases. Changed all
7514 callers.
7515 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
7516 Moved to...
7517 * m4/module.c (m4_set_module_builtin_table)
7518 (m4_set_module_macro_table): ...here, and renamed. Changed all
7519 callers.
7520 * m4/m4module.c (m4_module_data): This...
7521 * m4/m4private.c (struct m4_module_data): ...and this...
7522 * m4/module.c (module_data) ...consolidated here and no longer
7523 exported. Changed all callers.
7525 2003-06-16 Gary V. Vaughan <gary@gnu.org>
7527 Begin work on lifting the curse of the global variables. To start
7528 with create a `struct m4' context container, and replace
7529 `m4__symtab' with `context->symtab' throughout. This means
7530 initialising a context container in main, and adjusting many
7531 functions between main and the module entry points so that the
7532 container gets passed through. It would have been nice to
7533 defer this until after 1.5, but it has a major effect on the
7534 user's module writing ABI, so it needs to be addressed now - at
7535 least in the areas that impact the ABI. An interrelated change
7536 in the symtab API removes the dependency on a global symbol table,
7537 and instead focuses on a passed table (from the context
7538 container).
7540 * TODO: Reminders for finishing context functionality.
7541 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
7542 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
7543 global variables and eventually allow m4 to be reentrant.
7544 * m4/m4private.h (m4): Define the new structure here...
7545 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
7546 don't carry the overhead of a function call.
7547 * m4/m4module.h: Prototype extern functions from m4/m4.c.
7548 (m4): Declare type for new struct m4 objects.
7549 (M4SYMTAB): User macro to ease finding the symbol table for the
7550 current context for module developers.
7551 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
7552 verb.
7553 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
7554 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
7555 (m4_call_macro, m4_dump_symbols, m4_expand_input)
7556 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
7557 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
7558 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
7559 m4* context parameter. Changed definitions and all callers.
7560 (m4_symtab): Alias for m4_hash to decouple the
7561 m4_symtab api from m4_hash.
7562 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
7563 m4_hash.
7564 (m4_symtab_create): New function to return an initialised
7565 m4_symtab.
7566 (m4_symtab_delete): New function to delete an m4_symtab's memory.
7567 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
7568 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
7569 instead of simply using the global m4__symtab. Changed
7570 definitions and all callers.
7571 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
7572 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
7573 * src/main.c (main): Create a context and use that instead of the
7574 former global m4__symtab.
7576 2003-06-13 Gary V. Vaughan <gary@gnu.org>
7578 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
7579 to the callback. Callbacks should not need to hardcode the
7580 hashtable they are working from, nor should we have to waste the
7581 userdata parameter to pass the table in.
7582 * m4/hash.h (m4_hash_apply_func): Require the initial table
7583 parameter.
7584 * m4/symtab.c (symtab_destroy): Use the passed table instead
7585 of hardcoding m4__symtab.
7586 (m4_symbol_popdef): Don't use the userdata parameter to pass the
7587 table to arg_destroy.
7588 (arg_destroy): Use the hash parameter, ignore userdata.
7589 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
7590 prototype.
7591 (traceon, traceoff): Call set_trace with the extra initial
7592 parameter.
7594 2003-06-13 Gary V. Vaughan <gary@gnu.org>
7596 More refactoring to stabilise the module api, this time for
7597 symtab.c. Additionally, start to pay attention to function names
7598 that don't contain a verb like they should.
7600 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
7601 wrapper for m4_hash_apply to decouple the symtab module from the
7602 hash module.
7603 (m4_symbol_builtin, m4_symbol_macro): Renamed to
7604 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
7605 callers.
7606 (m4_symbol_delete): Create a macro version to save a function
7607 call.
7608 (m4_token_t, m4_data_t): These violate the POSIX reserved
7609 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
7610 all callers.
7611 (m4_token_type): Renamed to m4_token_get_type.
7612 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
7613 (m4_symtab_exit): Removed from the exported module
7614 api...
7615 * m4/m4private.h (m4__symtab, m4__symtab_init)
7616 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
7617 renamed and added to the internal api. Changed all callers.
7618 (m4_symtab_apply): A faster macro version of the function for
7619 users of the internal api.
7620 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
7621 symbol_destroy and arg_destroy.
7622 (symtab_debug): Added a prototype.
7623 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
7624 so that callers in this file get the faster macro versions from
7625 m4/m4private.h.
7627 2003-06-12 Gary V. Vaughan <gary@gnu.org>
7629 Refactoring modules to rationalise the API into an external
7630 documented (eventually!) API for use by modules in the `m4_'
7631 namespace declared in m4/m4module.h, an internal API between the
7632 source files we ship (including our shipped modules) in the `m4__'
7633 namespace declared in m4/m4private.h and making the rest as
7634 cohesive as possible with liberal use of the `static' keyword.
7635 This change represents an audit to m4/module.c along these
7636 guidelines.
7638 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
7639 Removed. No longer used.
7640 (m4_module_close): Removed prototypes.
7641 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
7642 from the exported module api...
7643 * m4/m4private.h (m4__module_init, m4__module_open)
7644 (m4__module_exit): ...and renamed and added to the internal api.
7645 Changed all callers.
7646 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
7647 Centralised definitions after renaming...
7648 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
7649 (M4_FINISH_SYMBOL): ...and removing from here.
7650 (m4_module_dlerror, m4_module_remove, m4_module_close)
7651 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
7652 module_remove, module_close and caller_id.
7653 (MODULE_SELF_NAME): New macro to make reporting self errors
7654 easier.
7655 (m4_module_load, module_close, module_remove): Use it.
7656 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
7657 name.
7658 * src/main.c (main): Use it.
7660 2003-06-12 Gary V. Vaughan <gary@gnu.org>
7662 * README: Remove references to --enable-changeword, which has been
7663 removed from the code.
7665 2003-06-11 Gary V. Vaughan <gary@gnu.org>
7667 Getting rid of the annoying bug with configure --enable-debug,
7668 which spewed -e: command not found errors. This was an interaction
7669 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
7670 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
7671 branch-1-5) to get the full fix.
7673 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
7674 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
7675 and then use the probed value of $SED.
7676 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
7677 this, it messes up the AC_REQUIRE stack.
7679 2003-06-10 Gary V. Vaughan <gary@gnu.org>
7681 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
7682 the destroy callback.
7683 (m4_arg_destroy): Use the hash address to free the hash node key
7684 field.
7686 2003-06-06 Gary V. Vaughan <gary@gnu.org>
7688 First cut at formal parameters in macros.
7690 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
7691 * m4/xstrzdup.c: New file.
7692 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
7693 associative array of parameter names to details.
7694 (m4_symbol_token): Capture macro names with parameter lists.
7695 (m4_arg_signature_parse): And build an associative array to hang
7696 from the symbol structure to map names to details.
7697 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
7698 m4_hash_resize idiom. Now that we potentially add a little hash
7699 table to many of the entries in the symbol table, added an extra
7700 arg to set the initial size. Changed all callers.
7701 (m4_hash_apply): New function that is basically a generalised
7702 version of...
7703 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
7704 all callers to call m4_hash_apply instead.
7705 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
7706 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
7707 m4_arg_signature association that might be attached to the symbol,
7708 * m4/hash.h (m4_hash_apply_func): Replacement type for...
7709 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
7710 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
7711 parameter lists.
7712 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
7713 (M4_IS_IDENT): Detect characters that can be safely used in
7714 parameter names.
7715 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
7716 * m4/macro.c: Corrected grammar in some comments. Use `token'
7717 rather than `td' for m4_token variables.
7718 (m4_process_macro): If we find a dollar followed by some
7719 M4_IS_IDENT characters, replace that with the contents of the argv
7720 entry with offset stored in the m4_token_arg associated with the
7721 collected identifier.
7723 2003-06-05 Gary V. Vaughan <gary@gnu.org>
7725 Begin preparations for supporting formal parameters in m4 macros.
7727 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
7728 the details of a formal parameter.
7729 (m4_token): Add an arg_signature member to hold a hash table for
7730 looking up formal parameters.
7731 * m4/input.c: Update more bitrotted comments.
7732 (m4_push_builtin): Initialise arg_signature member.
7733 (init_builtin_token): Copy arg_signature member.
7734 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
7735 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
7736 replace...
7737 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
7738 (m4_macro_pushdef, m4_macro_define): ...these, And...
7739 (m4_symbol_token): ...wrapped around this new function, which
7740 vastly simplifies the arguments required by the functions it
7741 replaces.
7742 Changed all callers.
7744 2003-06-05 Gary V. Vaughan <gary@gnu.org>
7746 * m4/macro.c: Format changes.
7748 2003-06-04 Gary V. Vaughan <gary@gnu.org>
7750 * m4/input.c: Updated various bitrotted comments.
7751 (m4_push_builtin): Just pass the whole m4_token, rather than
7752 extracting all the fields in the caller. This also allows us to
7753 check the token type for consistency.
7754 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
7755 Renamed to builtin_funcs, builtin_peek, builtin_read,
7756 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
7757 the code. Changed all callers.
7758 (struct input_block): Similarly renamed u_m member to u_b, and
7759 changed all callers.
7760 (m4_next_token): Use bzero to initialise the data fields.
7761 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
7763 2003-05-29 Gary V. Vaughan <gary@gnu.org>
7765 These changes were necessary to get m4 to build on my iBook
7766 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
7767 (GCC) 3.1 20020420 (prerelease)":
7769 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
7770 inclusion of module loader headers.
7771 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
7772 * m4/Makefile.am: Ditto.
7773 (libm4_la_LIBADD): Added $(LTLIBINTL).
7774 * m4/utility.c (program_name): Removed declaration in favour of
7775 the one already in error.c!
7776 * m4/m4module.h (program_name): Define to program_invocation_name
7777 when using GNU C library. Use an explicit extern declaration.
7778 (interactive, sync_output, debug_level, hash_table_size)
7779 (no_gnu_extensions, prefix_all_builtins, max_debug_argument_length)
7780 (suppress_warnings, warning_status, nesting_limit, discard_comments)
7781 (lquote, rquote, bcomm, ecomm, m4_bad_argc, m4_skip_space)
7782 (m4_numeric_arg, m4_shipout_int, m4_shipout_string, m4_dump_args)
7783 (m4_debug, m4_debug_init, m4_debug_exit, m4_debug_decode)
7784 (m4_debug_flush_files, m4_debug_set_output, m4_debug_message_prefix)

7786 (m4_expansion_level, m4_expand_ranges, m4_expand_input)
7787 (m4_call_macro, m4_process_macro, m4_syntax_table, m4_current_file)
7788 (m4_current_line, m4_current_diversion, m4_output_current_line):
7789 Don't rely on default, use an explicit extern.
7790 * m4/error.h (error, error_at_line, error_print_progname)
7791 (error_message_count, error_one_per_line): Ditto.
7792 * m4/ltdl.c: Update from CVS libtool.
7793 * m4/ltdl.h: Ditto.
7794 * commit: Update from CVS cvs-utils.
7796 2002-11-04 gettextize <bug-gnu-gettext@gnu.org>
7798 * po/Makefile.in.in: Upgrade to gettext-0.11.5.
7799 * po/boldquot.sed: New file, from gettext-0.11.5.
7800 * po/en@boldquot.header: New file, from gettext-0.11.5.
7801 * po/en@quot.header: New file, from gettext-0.11.5.

7804 * po/remove-potcdate.sin: New file, from gettext-0.11.5.
7805 * po/Rules-quot: New file, from gettext-0.11.5.
7807 2002-11-04 Akim Demaille <akim@epita.fr>
7809 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
7810 running m4 itself.
7811 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
7813 2002-11-04 Akim Demaille <akim@epita.fr>
7815 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
7817 2002-11-04 Akim Demaille <akim@epita.fr>
7819 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
7820 used as `external', and Libtool 1.4.3.
7821 (LINGUAS): Remove.
7822 (LTLIBOBJS): Don't play with it.
7823 * intl/: Remove.
7824 * Makefile.am (SUBDIRS): Remove intl.
7825 (ACLOCAL_AMFLAGS): Add -I config.
7826 (EXTRA_DIST): Add config/config.rpath.
7827 * po/LINGUAS: New.
7828 * po/Makevars: New.
7829 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
7831 2002-05-29 Gary V. Vaughan <gary@gnu.org>
7833 Preparations for refactoring syntax tables to allow reverse
7834 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
7835 speed of normal lookups in an array of unsigned short.
7837 * m4/input.c (single_quotes, single_comments, use_macro_escape):
7838 Moved from here...
7839 * m4/m4private.h (m4__single_quotes, m4__single_comments,
7840 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
7841 is for internal symbols which unavoidably pollute the global
7842 namespace, but are not published APIs.
7843 Adjusted all callers.
7844 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
7845 m4_set_comment, m4_set_syntax, set_syntax_internal,
7846 unset_syntax_attribute): Moved from this file...
7847 * m4/syntax.c: New. ...to this file.
7848 Also added an m4_syntax_exit stub for orthogonality.
7849 * src/main.c (main): Use it.
7850 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
7851 * m4/m4module.h: Reformatting. New prototypes.
7853 2002-05-29 Gary V. Vaughan <gary@gnu.org>
7855 * bootstrap (aclocal_apiversion): The aclocal apiversion is
7856 distinct from the automake release number (in that the apiversion
7857 apparently has no micro-version-component).
7858 (aclocal_apilibdir): Use it.
7860 2002-05-28 Gary V. Vaughan <gary@gnu.org>
7862 * m4/hash.c (m4_hash_resize): New function.
7863 * m4/hash.h: Add prototype.
7864 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
7865 benchmarking to find a good value for, say, autoconf. This is
7866 already a little quicker than before for me.
7868 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
7869 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
7870 and reenamed.
7871 * m4/hash.h: Adjust prototypes.
7873 2002-01-22 Akim Demaille <akim@epita.fr>
7875 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
7876 APIVERSION scheme.
7877 * tests/Makefile.am (package.m4): New.
7878 * tests/atlocal.in: Adjust to CVS Autotest.
7879 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
7880 * configure.ac: LIBOBJ is a forbidden string.
7881 Simplify AM_INIT_AUTOMAKE invocation.
7882 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
7883 options.m4.
7885 2002-01-21 gettextize <bug-gnu-utils@gnu.org>
7887 * po/Makefile.in.in: Upgrade to gettext-0.10.40.
7889 2001-10-19 Akim Demaille <akim@epita.fr>
7891 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
7893 2001-10-19 Akim Demaille <akim@epita.fr>
7895 * m4/input.c (m4_next_token): Display where was opened what is
7896 not closed.
7898 2001-10-19 Akim Demaille <akim@epita.fr>
7900 * m4/macro.c (expand_argument): Display where was opened what is
7901 not closed.
7903 2001-10-18 Akim Demaille <akim@epita.fr>
7905 * m4/input.c, modules/m4.c: Formatting changes.
7907 2001-10-17 Gary V. Vaughan <gary@gnu.org>
7909 * bootstrap: s/configure.in/configure.ac/
7911 2001-10-16 Gary V. Vaughan <gary@gnu.org>
7913 * m4/symtab.c (m4_symbol_destroy): This function calls
7914 m4_symbol_popdef, which recycles a symbols memory when the last
7915 definition is popped. Since we were passing the address of the
7916 symbol name found in the symbol table, and it was being removed
7917 partway through m4_symbol_destroy() we were referencing freed
7918 memory for the balance of the function. Now we take a copy of the
7919 symbol name tring and use that as a key into the symbol
7920 table... that way if the original symbol name is freed, the copy
7921 is still valid.
7923 2001-10-13 Akim Demaille <akim@epita.fr>
7925 * m4/ltdl.c: Update.
7927 2001-10-13 Akim Demaille <akim@epita.fr>
7929 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
7930 Don't gettextize internal error messages.
7932 2001-10-13 Akim Demaille <akim@epita.fr>
7934 * tests/macros.at (Arity and defn): New failing test.
7935 (Arity, defn, and freeze): New.
7937 Fix `Arity and defn'.
7939 * m4/input.c (m4_push_macro): Don't forget the arity.
7940 * modules/m4.c (defn): Likewise.
7942 2001-10-13 Akim Demaille <akim@epita.fr>
7944 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
7945 to...
7946 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
7947 (Propagation of traceon, Propagation of --trace): this new file.
7949 2001-10-13 Akim Demaille <akim@epita.fr>
7951 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
7952 interface instead of (name, argc...).
7953 Upon failure, specify which argument was guilty.
7954 Adjust callers.
7956 2001-10-13 Akim Demaille <akim@epita.fr>
7958 * modules/evalparse.c: Save translators' time: don't translate
7959 internal error messages.
7960 (m4_evaluate): Simplify/normalize error messages.
7961 * doc/m4.texinfo (Eval): Adjust.
7963 2001-10-13 Akim Demaille <akim@epita.fr>
7965 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
7966 where no checking is needed.
7967 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
7968 interface instead of (name, argc...).
7969 Adjust callers.
7970 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
7971 elsewhere.
7973 2001-10-13 Akim Demaille <akim@epita.fr>
7975 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
7976 exclude the builtin name from the count.
7977 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
7978 calling ifelse with a single argument is valid.
7979 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
7980 with 1 and 2 args, mostly to strengthen the test suite.
7982 2001-10-13 Akim Demaille <akim@epita.fr>
7984 * m4/output.c (m4_make_diversion, m4_insert_file)
7985 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
7987 2001-10-12 Gary V. Vaughan <gary@gnu.org>
7989 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
7990 since we call these things builtins in the rest of the code!
7992 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
7994 2001-10-12 Gary V. Vaughan <gary@gnu.org>
7996 Rather than forcing each builtin definition to manage its own
7997 argument range checking, tabulate the maxima and minima for all
7998 builtins in each module. This forces us to consider what the
7999 valid ranges for each builtin should be, and moves the checking
8000 code out of each builtin implementation and into the builtin
8001 caller infrastructure.
8003 * m4/m4module.h (struct m4_builtin): Add argument minima and
8004 maxima.
8005 * m4/m4private.h (struct m4_token): Reflect them here too.
8006 * m4/input.c (struct input_block): ...and here.
8007 (m4_token_copy): New function for token copying.
8008 (init_macro_token): Copy them from a token to the input stack.
8009 (m4_next_token): Don't forget to initialise them for text
8010 macros.
8011 * m4/macro.c (expand_argument): Use m4_token_copy, and also
8012 check argument counts before calling the builtin handler.
8013 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
8014 (m4_symbol_macro): Likewise.
8015 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
8016 parameters. Updated all callers.
8017 (m4_builtin_define): Ditto.
8018 (m4_macro_pushdef, m4_macro_define): Ditto.
8019 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
8020 * modules/evalparse.c: Declare argument counts for defined
8021 builtins and remove explicit calls to m4_bad_argc().
8022 * modules/gnu.c: Ditto.
8023 * modules/load.c: Ditto.
8024 * modules/m4.c: Ditto.
8025 * modules/modtest.c: Ditto.
8026 * modules/mpeval.c: Ditto.
8027 * modules/perl.c: Ditto.
8028 * modules/shadow.c: Ditto.
8029 * modules/stdlib.c: Ditto.
8030 * modules/time.c: Ditto.
8031 * TODO: Updated.
8033 2001-10-10 Gary V. Vaughan <gary@gnu.org>
8035 The trace semantics now attach the trace bit to a symbol name.
8036 For as long as a traceon(`foo') is active, calls to foo will be
8037 traced regardless of intervening undefines or module unloads.
8038 Fixed the flag propogation issues differently to the fixes
8039 reverted with the last attempt at nailing down trace:
8041 * m4/m4private.h: This file is not visible outside of the m4
8042 source tree, so I removed all the `M4_' and `m4_' prefixes to save
8043 on typing. Updated all clients.
8044 (m4_token): New typedef contains the fields that need to be passed
8045 around with the low level tokeniser.
8046 (m4_token_data): Removed.
8047 (m4_symbol): Now contains the traced flag again.
8048 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
8049 the trace bit set. This change is contained entirely within this
8050 module and doesn't leak out into the callers. Updated all
8051 clients.
8052 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
8053 new fields in m4_token. Updated all clients.
8054 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
8055 that `groks_macro_args' and `blind_if_no_args' flags are retained
8056 when defn() results are passed around in m4 code. Updated all
8057 callers.
8058 (m4_builtin_define): Ditto.
8059 (m4_macro_pushdef, m4_macro_define): Ditto.
8060 * m4/input.c (struct input_block): Add a flags field to facilitate
8061 the above.
8062 (m4_push_macro): ...use it.
8063 (init_macro_token): Retrieve it.
8064 (m4_next_token): Initialise it.
8065 * m4/macro.c (expand_argument): Copy it.
8066 * m4/m4module.h: Adjust.
8067 * tests/builtins.at: Adjust the expected output of the trace
8068 tests to reflect the change in semantics.
8069 * tests/modules.at (modules: trace): Check that unloading a
8070 module which supplies a traced symbol definition doesn't lose te
8071 trace bit.
8073 2001-10-07 Gary V. Vaughan <gary@gnu.org>
8075 * modules/gnu.c (m4_macro_table): Display the timetamp when
8076 expanding __m4_version__.
8078 * configure.ac (--with-modules): Forgot a comma in the
8079 AC_HELP_STRING parameter list.
8081 2001-10-05 Gary V. Vaughan <gary@gnu.org>
8083 * bootstrap: Remove aclocal.m4t when it is no longer required.
8085 2001-10-05 Akim Demaille <akim@epita.fr>
8087 * tests/Makefile.am: Adjust for gnuprog2.
8088 * tests/m4.in: There can be a leading path.
8089 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
8090 * tests/testsuite.at: Adjust to the most recent Autotest.
8091 (AT_CHECK_M4_FILTER): Fix and rename as...
8092 (AT_TEST_M4): this.
8093 * tests/others.at: Use it.
8095 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
8096 variable in shell scripts, one uses `$'...
8098 2001-10-04 Gary V. Vaughan <gary@gnu.org>
8100 * configure.ac: `rm -f $m4_getopt_h' was lost.
8102 2001-10-04 Gary V. Vaughan <gary@gnu.org>
8104 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
8105 time. Define it for config.h in order to...
8106 * src/main.c (main): ...display the timestamp for --version.
8108 2001-10-04 Akim Demaille <akim@epita.fr>
8110 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
8111 previous builtins `regexp' and `patsubst'.
8112 (regexp, patsubst): Use them.
8113 (eregexp, epatsubst): New builtins.
8114 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
8115 (Epatsubst and Patsubst, Eregexp and Regexp): these.
8116 (Extensions): More info on REs.
8118 2001-10-04 Akim Demaille <akim@epita.fr>
8120 * modules/modtest.c (init_handler): Consistently output to stderr.
8121 (finish_handler): New.
8122 (test): The `if' is an `assert'.
8123 * tests/modules.at: Adjust.
8125 2001-10-04 Akim Demaille <akim@epita.fr>
8127 * m4/utility.c (m4_bad_argc): Detail the mismatches.
8129 2001-10-01 Akim Demaille <akim@epita.fr>
8131 * tests/generate.awk: Tag the tests with `documentation'.
8132 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
8133 Use the make the existing modtest tests more uniform, and complete
8134 the set of possibilities.
8136 2001-10-01 Akim Demaille <akim@epita.fr>
8138 * config/gmp.m4: Consult the user before using GMP: use
8139 --without-gmp.
8140 * configure.ac: Adjust.
8141 * modules/gmp.c: No protection needed as the module is not built
8142 if GMP is not used.
8144 2001-10-01 Akim Demaille <akim@epita.fr>
8146 * tests/generate.awk: Remove debugging code.
8147 (fatal): Specify the current location.
8149 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
8150 * modules/gnu.c, modules/m4.c: Use M4ARG.
8152 2001-10-01 Akim Demaille <akim@epita.fr>
8154 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
8155 (m4_regexp_compile): New.
8156 (regexp, patsubst): Use it.
8158 2001-09-30 Gary V. Vaughan <gary@gnu.org>
8160 Reinstate the memory handling improvements from the patch I just
8161 reverted. Relevant ChangeLog entries repeated here:
8163 * m4/module.c (m4_module_remove): New function that holds the core
8164 of the old m4_module_unload.
8165 (m4_module_unload): Use it.
8166 (m4_module_unload_all): When we know the modules will never be
8167 used again (i.e. on exit), free up as much module memory as
8168 possible. There are still some artifacts from resident modules
8169 living inside ltdl.c, but everything else is freed.
8170 * m4/debug.c (m4_debug_exit): Free memory allocated in
8171 m4_debug_init().
8172 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
8173 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
8174 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
8175 * m4/m4module.h: Updated prototypes.
8176 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
8177 * m4/hash.h: Updated prototypes.
8178 * src/main.c (main): Use all these new functions to clean up as
8179 much memory as possible before exit.
8181 2001-09-30 Gary V. Vaughan <gary@gnu.org>
8183 Reverted my large patch for removing the old m4_symbol
8184 structure on 2001-09-20. We are still not happy about the way
8185 trace works in conjunction with defn and undefine, and leaving
8186 the reverted patch active prevents us from moving the traced
8187 bit from the definition back to the symbol.
8189 2001-09-30 Gary V. Vaughan <gary@gnu.org>
8191 * configure.in: Moved to...
8192 * configure.ac: ...here. Added a libtool like timestamped
8193 banner, and tidied up the libltdl cruft.
8194 * config/mkstamp: Script to extract a timestamp from ChangeLog.
8195 * modules/Makefile.am (INCLTDL): Removed. This is required
8196 only when libltdl is configured in a subdirectory.
8197 * src/Makefile.am: Ditto.
8198 (LIBADD_DL): No need to add this again, libtool already knows
8199 that libm4.la depends on it.
8200 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
8201 them.
8203 * TODO: stackovf.c is basically broken.
8204 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
8206 2001-09-28 Akim Demaille <akim@epita.fr>
8208 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
8210 2001-09-27 Akim Demaille <akim@epita.fr>
8212 * tests/m4.in: Don't use short options.
8213 Simplify the stderr signature normalization.
8215 2001-09-27 Akim Demaille <akim@epita.fr>
8217 tests/m4 shall be position independent.
8219 * tests/m4.in: New.
8220 * tests/m4: Remove.
8221 * tests/testsuite.at: No args to AT_INIT.
8222 * configure.in, tests/Makefile.am: Adjust.
8224 2001-09-22 Akim Demaille <akim@epita.fr>
8226 Autotest has changed again.
8228 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
8229 (package.m4): Remove.
8230 * configure.in: Adjust to LIBADD_GMP.
8232 2001-09-21 Gary V. Vaughan <gary@gnu.org>
8234 * config/gmp.m4 (AC_ARG_WITH): Removed.
8235 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
8236 (AC_LIB_GMP): When performing a test compile against libgmp,
8237 include the header gmp.h if possible, and link against -lgmp. If
8238 they both work define USE_GMP.
8239 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
8240 (mpeval_LTX_init_func): Complain on load that there was no libgmp
8241 at compile time.
8243 2001-09-20 Gary V. Vaughan <gary@gnu.org>
8245 * m4/evalparse.c: Moved to...
8246 * modules/evalparse.c: ...here. This code is shared between
8247 modules/mpeval.c and modules/m4.c, so there is no need to pollute
8248 the libm4 API with its details. Moderately rewritten to interface
8249 into its clients more simply.
8250 * m4/eval.c: Deleted. Migrated functionality to...
8251 * modules/m4.c: ...here.
8252 (builtin_eval): Implemented in terms of the new interface style.
8253 * modules/mpeval.c (builtin_mpeval): Ditto.
8254 * m4/m4module.h: Removed references to the former m4/eval.c.
8255 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
8256 (EXTRA_libm4_la_SOURCES): Deleted.
8257 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
8258 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
8260 2001-09-20 Akim Demaille <akim@epita.fr>
8262 * config/gmp.m4 (AM_WITH_GMP): Rename as...
8263 (AC_LIB_GMP): this.
8264 By default, use gmp.
8265 Massive revamping.
8266 * configure.in: Adjust.
8267 Use Automake conditionals for USE_GMP.
8268 Always compute sizeof (long long int).
8269 This was a bug BTW, as `eval' (not `mpeval') depends on it:
8270 before, it was used _only_ if mpeval was not activated.
8271 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
8272 (mpeval_la_LIBADD): New macros.
8273 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
8274 Indent.
8275 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
8276 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
8277 WITH_GMP.
8279 2001-09-20 Akim Demaille <akim@epita.fr>
8281 * tests/Makefile.am (package.m4): New.
8282 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
8284 2001-09-20 Gary V. Vaughan <gary@gnu.org>
8286 More cleanup. After the last patch, m4_symbol holds nothing but
8287 the head of a chain of m4_token_data. So I have removed the old
8288 m4_symbol, so that m4_token_data chains are stored directly in the
8289 value cell of a hash table node. But there's more... m4_symbol
8290 was a more natural name for the symbol value cell, and now that it
8291 is gone I have renamed the former m4_token_data structure to
8292 m4_symbol. This change turned out to be a pig to get right, since
8293 the original code didn't need to modify the value cell itself,
8294 since changing the chain happened inside the m4_symbol that used
8295 to be returned -- I had to pass the address of the value cell
8296 across various function calls, incase the head value changed. I
8297 also tightened up the memory management to help me find a nasty
8298 memory corruption bug that took me all night to track down...
8300 * m4/m4private.h (struct m4_symbol): Removed.
8301 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
8302 all references.
8303 * m4/hash.c (m4_hash_iterator_value): Return the address of the
8304 value cell. Updated all callers.
8305 * m4/symtab.c: Took advantage of the simplification in the data
8306 structures to rewrite a lot of this file more simply. There is
8307 still some room for optimisation here, but we should tackle that
8308 systematically closer to the release.
8310 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
8311 revealed. This version is ahead of CVS libtool until I get chance
8312 to flush my changes.
8313 * m4/module.c (m4_module_remove): New function that holds the core
8314 of the old m4_module_unload.
8315 (m4_module_unload): Use it.
8316 (m4_module_unload_all): When we know the modules will never be
8317 used again (i.e. on exit), free up as much module memory as
8318 possible. There are still some artifacts from resident modules
8319 living inside ltdl.c, but everything else is freed.
8320 * m4/debug.c (m4_debug_exit): Free memory allocated in
8321 m4_debug_init().
8322 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
8323 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
8324 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
8325 * m4/m4module.h: Updated prototypes.
8326 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
8327 * m4/hash.h: Updated prototypes.
8328 * src/main.c (main): Use all these new functions to clean up as
8329 much memory as possible before exit.
8331 2001-09-18 Gary V. Vaughan <gary@gnu.org>
8333 The `traced' flag needs to be attached to the definition of a
8334 symbol rather than the current symbol containing the definition.
8335 Implementing this showed up some long standing post 1.4 bugs in
8336 flag propogation which I also fixed.
8338 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
8339 (struct m4_token_data): And add it back in here.
8340 * m4/input.c (init_macro_token): Propogate the traced flag
8341 correctly.
8342 * m4/macro.c (expand_argument): Ditto.
8343 * tests/builtins.at (trace2, trace3): New tests based on Akim's
8344 sadistic email ;-)
8346 2001-09-08 Gary V. Vaughan <gary@gnu.org>
8348 * m4/m4private.h (struct m4_token_data): Simplified by removing
8349 the redundant `traced' flag, and one level of structure nesting.
8350 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
8351 * m4/input.c (init_macro_token): No need to initialise removed
8352 `traced' field.
8353 * m4/macro.c (expand_argument): No need to copy it either.
8354 * m4/utility.c (m4_token_data_func_traced): Or provide an access
8355 function.
8357 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
8358 dependant on multiple symbols with the same key, so preserving
8359 relative symbol order in each bucket during resizing is no longer
8360 required. The resize function is considerably faster as a result.
8362 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
8363 s/m4_symbol_insert/m4_symbol_define/g;
8364 s/m4_builtin_insert/m4_builtin_define/g;
8365 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
8367 2001-09-08 Gary V. Vaughan <gary@gnu.org>
8369 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
8370 commits, the m4_lookup_symbol dispatch function is split into
8371 specialised functions that must be called directly.
8373 * m4/m4module.h (m4_symbol_lookup_t): Removed.
8374 * m4/symtab.c (m4_lookup_symbol): Removed.
8375 (m4_symbol_builtin, m4_symbol_macro): New functions.
8376 * m4/builtin.c (m4_builtin_define): Split into...
8377 (m4_builtin_pushdef, m4_builtin_insert): ...these.
8378 (m4_macro_define): Split into...
8379 (m4_macro_pushdef, m4_macro_insert): ...these.
8380 * src/main.c (main): Set command line macros from `-D' parameters
8381 using `m4_macro_define'.
8383 2001-09-08 Gary V. Vaughan <gary@gnu.org>
8385 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
8386 this from m4_remove_table_reference_symbols().
8387 * m4/m4module.h, m4/module.c: Updated all references.
8389 2001-09-07 Akim Demaille <akim@epita.fr>
8391 * modules/stdlib.c, modules/times.c: Misc cleanups.
8393 2001-09-07 Akim Demaille <akim@epita.fr>
8395 * configure.in: We now need Autoconf 2.52e.
8396 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
8397 and `M4_SYMBOL_DELETE'.
8398 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
8399 * src/main.c (main): Adjust.
8401 2001-09-06 Gary V. Vaughan <gary@gnu.org>
8403 Fix the obstack.h problem once and for all! At configure time we
8404 can test for a system supplied obstack.h: depending on the
8405 result, we now generate system.h with an #include of the correct
8406 header. As a bonus, I've also added a --with-included-obstack,
8407 incase the user doesn't like the system obstack for some
8408 reason... and also we can test the shipped obstack on a system
8409 that has oe of its own. We also now need to be careful to add
8410 build directories to the include search path, since the generated
8411 system.h will be in the build tree.
8413 * configure.in (AC_CONFIG_FILES): Generate system.h from
8414 system-h.in.
8415 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
8416 include the system obstack header or the copy shipped with M4.
8417 Allow the user to override configure and force the build to use
8418 the shipped version.
8419 * m4/system-h.in: New file, template for...
8420 * m4/system.h: ...this. Now deleted.
8421 * m4/m4module.h: Include system.h before everything else.
8422 * src/freeze.c: Ditto.
8423 * m4/Makefile.am (dist-hook): Remove generated system.h.
8424 (INCLUDES): Check builddir for generated headers before checking
8425 srcdir.
8426 * modules/Makefile.am (INCLUDES): Ditto.
8427 * src/Makefile.am (INCLUDES): Ditto.
8429 2001-09-05 Gary V. Vaughan <gary@gnu.org>
8431 * TODO: Remove the items that have been addressed already.
8433 2001-09-05 Akim Demaille <akim@epita.fr>
8435 * src/main.c (main): Standardize --version.
8437 2001-09-05 Akim Demaille <akim@epita.fr>
8439 * modules/format.c (format): Have a bigger `str'.
8441 2001-09-05 Akim Demaille <akim@epita.fr>
8443 Rationalize warnings, reporting the macro name as if it were a
8444 program name, and assertions.
8446 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
8447 (M4WARN): New.
8448 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
8449 (m4_symbol_delete):
8450 Use assert for internal errors.
8451 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
8452 M4WARN.
8453 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
8454 M4WARN and assert.
8455 * tests/builtins.at (pushpop): Adjust.
8457 2001-09-05 Akim Demaille <akim@epita.fr>
8459 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
8460 with pointers.
8462 2001-09-05 Akim Demaille <akim@epita.fr>
8464 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
8465 * m4/macro.c, m4/symtab.c: Adjust.
8467 2001-09-05 Akim Demaille <akim@epita.fr>
8469 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
8470 (m4_symbol_pop, m4_symbol_del): this.
8471 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
8472 (m4_symbol_popdef, m4_symbol_delete): New.
8473 (m4_lookup_symbol): Adjust.
8474 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
8476 2001-09-05 Akim Demaille <akim@epita.fr>
8478 * m4/m4module.h (m4_symbol_lookup): Rename as...
8479 (m4_symbol_lookup_t): this.
8481 2001-09-05 Akim Demaille <akim@epita.fr>
8483 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
8484 unused.
8485 * m4/symtab.c (m4_lookup_symbol): Adjust.
8487 2001-09-03 Gary V. Vaughan <gary@gnu.org>
8489 Bootstrap will now work with Libtool 1.4.1 or higher:
8490 * bootstrap: Remove stale autom4te.cache files when
8491 rebootstrapping.
8492 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
8493 libtool.m4.
8494 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
8495 libtool.m4 directly.
8496 Run libtoolize to refresh ltmain.sh.
8497 * config/ltmain.sh: Deleted.
8498 * acinclude.m4: Deleted.
8499 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
8501 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
8502 implementation for the cvs impaired libtool user.
8504 2001-09-03 Akim Demaille <akim@epita.fr>
8506 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
8507 internal errors.
8508 Avoid using `default' in switch, as it hides useful compiler
8509 warnings when a case is forgotten.
8511 2001-09-03 Akim Demaille <akim@epita.fr>
8513 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
8514 is no such thing as `WITH_MODULES'.
8516 2001-09-03 Akim Demaille <akim@epita.fr>
8518 Improve the test suite's selfcontainedness.
8520 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
8521 (Include, Undivert): Tag the other input files.
8522 * tests/generate.awk: Catch `@comment file:'.
8523 `-I $src' is no longer needed.
8524 `next' is really like `return': the rest is skipped.
8525 Adjust to `input.m4'.
8526 (fatal): New function.
8527 * tests/foo, tests/incl.m4: Remove.
8529 2001-09-01 Gary V. Vaughan <gary@gnu.org>
8531 The shadowing mechanism and, infact, the whole symbol table
8532 implementation was creaking under the weight of the features piled
8533 on top of it. We now have a separate hash table module which will
8534 dynamically resize to keep symbol density withing good performace
8535 limits, and a new symtab module layered above it. Symbol lookups
8536 are now marginally more efficient (since the shadowed flag is no
8537 longer required) and symbol removal, such as on module unload, is
8538 considerably faster due to a reorganisation of the data structures
8539 used in symtab.c.
8541 * src/main.c (main): Don't mention `-H'.
8542 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
8543 effect.
8544 * NEWS: Updated.
8545 * m4/hash.c: New generalised dynamic hash table data structure
8546 management module.
8547 * m4/hash.h: Public interface.
8548 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
8549 (libm4_la_SOURCES): Add hash.c.
8550 * m4/symtab.c: More or less rewritten from scratch, within the
8551 bounds of the previous API.
8552 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
8553 call. Updated all callers.
8554 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
8555 declarations to reflect API changes.
8556 (M4INIT): Generate a declaration too, to avoid the warning with
8557 --enable-debug builds.
8558 (M4FINISH): Ditto.
8559 (HASHMAX): Removed.
8560 * m4/utility.c (hash_table_size): Removed.
8561 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
8562 names, which are then looked up by builtin_dumpdef() as necessary.
8563 This implies a small speedup in builtin_symbols(), which discarded
8564 all of the symbol info under the old call.
8565 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
8566 shadowing is implicit in respect to the new data structures.
8567 symbol names are no longer duplicated here, they are stored in the
8568 key field of the hash table.
8569 Moved macro_args and blind_no_args...
8570 (m4_token_data): ...to here.
8571 m4/macro.c (expand_macro): Added a name argument since the symbol
8572 name is no longer copied into each struct m4_symbol. Modified all
8573 callers.
8574 (collect_arguments): Ditto.
8575 * modules/m4.c (set_trace): Ditto.
8576 * modules/gnu.c (builtin_symbols): Updated.
8577 * src/freeze.c (produce_symbol_dump): Much improved in light of
8578 the improved symbol table layout.
8580 2001-09-01 Gary V. Vaughan <gary@gnu.org>
8582 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
8583 to M4_SYMBOL_NEXT.
8584 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
8585 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
8586 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
8587 SYMBOL_HANDLE): Ditto.
8588 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
8589 modules/gnu.c, modules/m4.c, src/freeze.c,
8590 src/main.c: Updated all references.
8592 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
8593 Automake 1.5 chokes on dynamic source file lists, Besides, it is
8594 already listed in m4_LDADD... how did that ever used to work?
8595 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
8596 link.
8597 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
8598 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
8600 * tests/m4: Don't call the m4 wrapper script with libtool, it
8601 works fine all by itself.
8603 2001-08-30 Gary V. Vaughan <gary@gnu.org>
8605 The experimental `changeword' feature never took off, and has
8606 no obvious advantages over `changesyntax' to compensate the
8607 enormous speed penalty it carries:
8608 * configure.in (ENABLE_CHANGEWORD): Removed.
8609 * m4/m4module.h (m4_set_word_regexp): Removed.
8610 * m4/m4private.h (m4_token_data): Removed original_text field.
8611 * m4/utility.c (m4_token_data_orig_text): Removed.
8612 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
8613 * m4/macro.c: Ditto.
8614 * src/main.c: Ditto.
8615 * modules/Makefile.am (changeword.la): Removed.
8616 * modules/changeword.c: File removed.
8617 * doc/m4.texinfo: References to changeword and --word-regexp
8618 removed.
8619 * po/POTFILES.in: modules/changeword.c removed.
8620 * tests/atlocal.in (ENABLE_CHANGEWORD): Removed.
8621 * tests/builtins.at (changeword): Test removed.
8623 2001-08-30 Akim Demaille <akim@epita.fr>
8625 * bootstrap.sh: Create aclocal.m4 instead of modifying it.
8626 This also help having a single list of m4 files: in
8627 config/Makefile.am.
8628 * config/Makefile.am (STANDARD_MACROS): Rename as...
8629 (ACLOCAL_MACROS): this.
8630 (list-standard-macros): Remove.
8631 (spy): New.
8633 2001-08-29 Gary V. Vaughan <gary@gnu.org>
8635 In an attempt to moderate my egomania...
8636 * tests/modules.at: Remove attributions.
8638 * tests/generate.awk: When making substitutions to "@&t@", either
8639 "&" or "\&" in the substitution string argument to gsub refer back
8640 to the matched text. "@\\&t@" seems to work though, Tests 43 and
8641 67 now pass for me.
8643 2001-08-29 Akim Demaille <akim@epita.fr>
8645 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)
8646 (include, indir, multiquotes, patsubst, pushdef/popdef, regexp)
8647 (sync-lines, trace, translit, undivert, wrap): Move to...
8648 * tests/builtins.at: this new file.
8649 * tests/others.at (Discard comments, import-environment): Move to...
8650 * tests/options.at: this new file.
8652 2001-08-29 Akim Demaille <akim@epita.fr>
8654 * tests/others.at (Freezing modules)
8655 (--module-directory: absolute path, modpath2, modpath3)
8656 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
8657 * tests/modules.at: here, new file.
8658 * tests/others.at, tests/generate.awk: Add a banner.
8659 * tests/testsuite.at: Adjust.
8660 (AT_CHECK_M4_FILTER): New, but unused.
8662 2001-08-29 Akim Demaille <akim@epita.fr>
8664 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
8665 handle that.
8666 * tests/others.at (wrap): Inline wrap.m4.
8667 (shadow): Inline shadow.m4.
8668 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
8669 * tests/m4: Simplify.
8671 2001-08-29 Akim Demaille <akim@epita.fr>
8673 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
8674 --language.
8676 2001-08-29 Akim Demaille <akim@epita.fr>
8678 * tests/generate.awk (normalize): s/@__@/@&t@/.
8680 2001-08-28 Akim Demaille <akim@epita.fr>
8682 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.
8684 2001-08-28 Gary V. Vaughan <gary@gnu.org>
8686 * bootstrap (generate.awk): Generate test cases with new script.
8688 2001-08-27 Akim Demaille <akim@epita.fr>
8690 * tests/Makefile.am (installcheck-local): Don't use
8691 `dc_install_base' which is not visible here, but `exec_prefix'
8692 which is clearly the RT anyway.
8693 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
8694 related to testing a now installed m4.
8695 * tests/m4: Do it here.
8697 2001-08-27 Akim Demaille <akim@epita.fr>
8699 * tests/others.at (indir): Formatting change.
8701 2001-08-27 Akim Demaille <akim@epita.fr>
8703 * tests/Makefile.am (installcheck-local): New.
8704 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
8705 the test suite.
8706 Prefer options over envvars.
8707 * src/main.c (main): First bug caught by the test suite (yeah!):
8708 --batch lacked a `break' which resulted in an accidental
8709 invocation of --discard-comments.
8711 2001-08-27 Akim Demaille <akim@epita.fr>
8713 * tests/others.at (capitalize, changeword, comments, ddivert)
8714 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
8715 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
8716 (sysv-args, trace, translit, undivert): Don't rely on files in
8717 examples/: AT_DATA them.
8719 2001-08-27 Akim Demaille <akim@epita.fr>
8721 Let the test suite use a wrapper around the not installed m4 to
8722 pretend it is (installed).
8724 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
8725 such a way that m4 does not process them.
8726 * configure.in: The package name seems to be `m4', not `M4'.
8727 * tests/m4: New.
8728 * tests/atlocal.in (at_package, M4): Remove.
8729 * tests/testsuite.at, tests/others.at: Use m4, not $M4.
8731 2001-08-27 Akim Demaille <akim@epita.fr>
8733 * tests/Makefile.am (CLEANFILES): Remove.
8734 (DISTCLEANFILES, clean-local): New.
8735 * examples/mktests.sh: Remove.
8737 2001-08-27 Akim Demaille <akim@epita.fr>
8739 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
8740 Don't use aclocal: it's written by hand.
8741 * aclocal.m4: m4_include all the files instead of being built by
8742 aclocal.
8743 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
8744 until it reads the traces by itself.
8745 * configure.in: Require Autoconf 2.42c as we are now using
8746 AC_CONFIG_TESTDIR instead of AT_CONFIG.
8747 Catch unexpanded `jm_' macros.
8748 * config/atconfig.m4: Remove.
8749 * config/error.m4: new.
8750 * config/Makefile.am: Ship the files included by aclocal.m4.
8751 * tests/Makefile.am (TESTSUITE_SOURCES): Rename as...
8752 (TESTSUITE_AT): this, to please Automake.
8753 (TESTSUITE): This target uses autotest/autotest.m4, not
8754 autotest/general.m4.
8755 * tests/testsuite.at: Prereq Autotest 2.52c.
8756 * examples/Makefile.am (pkgdata_DATA): Rename as...
8757 (dist_pkgdata_DATA): this.
8758 * doc/Makefile.am (man_MANS): Rename as...
8759 (dist_man_mans): this.
8761 2001-08-20 Gary V. Vaughan <gary@gnu.org>
8763 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
8764 Robert Collins, building on Cygwin no longer requires Windows
8765 import and export symbol decorations.
8766 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.
8767 * m4/error.h (M4_SCOPE) [cygwin*]: Ditto.
8768 * m4/debug.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
8769 * m4/error.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
8770 * m4/input.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
8771 * m4/macro.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
8772 * m4/output.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
8773 * m4/utilty.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
8774 * m4/xmalloc.c (M4_GLOBAL_DATA) [cygwin*]: Ditto.
8775 * configure.in (LIBM4_DLL_IMPORT) [cygwin*]: Don't set this
8776 anymore.
8777 * src/Makefile.am (AM_CPPFLAGS) [cygwin*]: Don't use it either!
8778 * modules/Makefile.am (AM_CPPFLAGS) [cygwin*]: Ditto.
8780 2001-08-20 Gary V. Vaughan <gary@gnu.org>
8782 Ansify the source. Previously we had a mix, where my code was
8783 in a K&R compatible style, and the preexisting code was in ANSI
8784 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
8785 and now the code base is much cleaner.
8787 * m4/system.h: Remove M4_PARAMS macro and all users. Remove
8788 VOID macro and all users.
8789 * m4/m4module.h: Ansify function prototypes and headers.
8790 * m4/builtin.c: Ditto.
8791 * m4/evalparse.c: Ditto.
8792 * m4/input.c: Ditto.
8793 * m4/macro.c: Ditto.
8794 * m4/module.c: Ditto.
8795 * m4/output.c: Ditto.
8796 * m4/path.c: Ditto.
8797 * m4/symtab.c: Ditto.
8798 * m4/utility.c: Ditto.
8799 * modules/format.c: Ditto.
8800 * modules/gnu.c: Ditto.
8801 * modules/m4.c: Ditto.
8802 * modules/mpeval.c: Ditto.
8803 * src/freeze.c: Ditto.
8804 * src/m4.h: Ditto.
8805 * src/main.c: Ditto.
8807 2001-08-20 Akim Demaille <akim@epita.fr>
8809 * config/atconfig.m4: s/EOF/ATEOF/, so that configure can be
8810 generated with stock 2.52.
8812 2001-08-20 Akim Demaille <akim@epita.fr>
8814 * config/atconfig.m4: New, until part of Autoconf per se.
8815 * configure.in (AT_CONFIG): Use it.
8816 Adjust.
8817 * tests/mkconfig.sh, tests/atconfig.in, tests/defs: Remove.
8818 * tests/atlocal.in: New.
8819 * tests/generate.awk: For the time being, the empty quadrigraph is
8820 `@__@'.
8821 * tests/others.at (changeword, gmp): Check the configuration
8822 variable against `yes'.
8823 * tests/testsuite.at (dnl): Allow it, as it's used all over the
8824 place.
8826 2001-08-20 Akim Demaille <akim@epita.fr>
8828 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
8829 * modules/m4.c (undivert): Disable the possibility of undiverting
8830 several files at once: it is not documented, it is inconsistent
8831 with the other macros, it can be straightforwardly mocked by
8832 several invocations, and most importantly, it prevents the
8833 possibility of other kinds of extension.
8834 Use `m4_numeric_arg'.
8836 2001-08-20 Akim Demaille <akim@epita.fr>
8838 * examples/include.m4: Typo.
8839 * tests/generate.awk: Really add it.
8840 * tests/Makefile.am: Adjust.
8841 * tests/others.at (Discard comments): It sure fails without `-c'.
8842 (include, undivert): Add -I examples/.
8844 2001-08-20 Akim Demaille <akim@epita.fr>
8846 Use sprintf, not ecft and friends since it is standard, portable,
8847 simplifies the code, and since the latter is even deprecated
8848 according to the GNU libc documentation.

8996 Drop Autoconf 2.13 compatibility.
8998 * configure.in (changeword): No need to undefine it, as anyway if

9000 And anyway, proper quotation is enough.
9001 (m4_pattern_allow): As it exists in 2.50, just use it.
9002 (AC_OUTPUT): Split in AC_CONFIG_FILES and AC_CONFIG_COMMANDS.

9051 (m4_modules): No longer required.
9052 (m4_module_init_t, m4_module_finish_t): POSIX namespace
9053 violations, renamed to...

9056 (M4INIT_HANDLER): Clean way to declare init functions in modules.
9057 (M4FINISH_HANDLER): And similarly for finish functions.
9058 * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER
9059 -- Add indirection to the CONC macro so that arguments are
9060 correctly expanded.
9061 * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
9062 * modules/shadow.c (m4_init_module): Ditto.
9063 Due to new init function semantics, be careful to perform the
9064 initialisation only on first load.
9065 * modules/perl.c (m4_init_module): Ditto. And Ditto.
9066 (m4_finish_module): Replaced with M4FINISH_HANDLER.

9068 finalisation only on first load.
9069 * m4/m4private.h (m4_module): Removed in favour of...
9070 (m4_module_data): ...structure without all the wrapper fields.
9071 Instances of this new structure are stored associated lt_dlhandles

9074 instead of the old module argument.
9075 (m4_builtin_table_install): Ditto.
9076 * modules/load.c (m4_resident_module): Removed. This is no
9077 longer implemented as a magic symbol...
9078 * modules/m4.c (m4_resident_module): Ditto.
9079 * modules/load.c (M4INIT_HANDLER): ...the module init function now
9080 uses the ltdl api to make the module resident.

9082 * modules/load.c (builtin_modules): Traverse the loaded module
9083 list with lt_dlhandle_next.

9092 (libm4_la_SOURCES): Delete list.c reference.

9094 eliminates many of the searches to find the handle associated with
9095 various tokens that are passed between functions.
9096 (struct m4_symbol): Removed the module field. The
9097 module association does not belong with the symbol...
9098 * m4/input.c (struct m4_builtin): ...it belongs with the builtin
9099 that the module implementation code is from. Added a handle
9100 field.
9101 (m4_push_macro): Add a `handle' argument. Changed all callers.
9102 (init_macro_token): Set the `handle' field for the
9103 m4_token_data.

9110 2001-08-15 Akim Demaille <akim@epita.fr>
9112 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Be sure `m4/' exists
9113 when creating `m4/obstack.h'.
9114 * tests/Makefile.am (TESTS_ENVIRONMENT): Pass top_srcdir and
9115 top_builddir.
9116 * tests/defs: Make them absolute.
9117 (CDPATH) Neutralize.
9118 * tests/gethem: Use them.
9120 2001-08-14 Gary V. Vaughan <gary@gnu.org>
9122 * config/ltmain.sh: Doh! Import again for a quoting fix that
9123 prevented any regression test from passing.
9125 * m4/m4module.h (obstack.h): Choose between installed version
9126 and shipped version based on configure tests.
9127 * src/freeze.c (obstack.h): Ditto.
9129 * acconfig.h: Removed. No longer required.
9131 * bootstrap: Rewritten to play nicely with Autoconf 2.5x.

9133 them to AC_INIT and AM_INIT_AUTOMAKE.
9134 * Makefile.am (AUTOMAKE_OPTIONS): Remove `gnits' which would
9135 disallow MY_NAME and MY_VERSION arguments to AM_INIT_AUTOMAKE.
9136 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Don't choke on
9137 shell variable m4_cv_func_obstack_h.
9138 * tests/defs (M4): Be more careful about relative path to libtool
9139 script and m4 binary by using $srcdir.
9141 * src/main.c (main): Use lt_dlinsertsearchdir to prepend -M
9142 optargs to the existing libltdl search path.
9143 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.
9144 * m4/ltdl.c: Updated.
9145 * m4/ltdl.h: Ditto.
9146 * config/ltmain.sh: Ditto.
9148 2001-08-11 Gary V. Vaughan <gary@gnu.org>
9150 * src/main.c (main): Add `-b' (for `batch') mode switch to force
9151 interactive mode off.
9153 2001-08-10 Akim Demaille <akim@epita.fr>
9155 * configure.in: Require Autoconf 2.52.
9156 (AC_ARG_PROGRAM): Remove, handled by Automake.

9173 string).
9175 2001-08-07 Akim Demaille <akim@epita.fr>
9177 Improve `make distcheck'.
9179 * configure.in: Be sure to be able to run `mkconfig.sh' when src
9180 != build.

9182 * doc/m4.texinfo (Include): Add missing blank.
9183 * m4/Makefile.am (EXTRA_DIST): Distribute gnu-obstack.h and

9211 interpreting the position of the decimal point correctly for
9212 whole numbers.
9214 2000-12-01 Gary V. Vaughan <gary@gnu.org>
9216 * TODO: Removed m4exit bug.
9217 * modules/load.c (m4_resident_module): Make this module resident.
9218 * module/m4.c (m4_resident_module): Ditto.
9219 * m4/modules.c (m4_module_load): Use new ltdl resident modules
9220 feature to mark modules as resident if they export

9223 with symbol insertion and deletion with resident modules.

9239 builtin.
9241 * src/main.c (usage): Added missing description of `-c' option.
9243 2000-11-29 Gary V. Vaughan <gary@gnu.org>
9245 Consolidate the myriad of dispersed test scripts into the
9246 tests subdirectory. I think I now have all the file where I
9247 want them, so there shouldn't be anymore upheaval =)O|
9248 Honest!
9249 * tests/Makefile.am: Updated to run the new tests added below.
9250 * tests/other-tests/capitalize.test, tests/other-tests/comments.test,

9288 Move the implementation of GMP support for the mpeval() builtin
9289 into a loadable module that depends on libgmp. mpeval() and
9290 eval() share a common parser, now in m4/evalparser.c; the code
9291 in m4/numb.c and m4/numb.h is now physically split between
9292 m4/eval.c (the eval() backend) and modules/mpeval.c (the
9293 mpeval() backend), rather than being differentiated by cpp
9294 macros and multiple inclusion. The mpeval module is always
9295 built but will generate an diagnostic if it is used from an
9296 installation that didn't link in the gmp library.
9297 * modules/Makefile.am: build and install the new mpeval module.
9298 * modules/mpeval.c: Now contains the former parts of m4/numb.c
9299 and m4/numb.h that are required for gmp support in mpeval().
9300 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
9301 * m4/evalmp.c: Removed.
9302 * m4/m4module.h: Removed conditional prototype for
9303 m4_mp_evaluate().
9304 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
9305 and m4/numb.h that do not rely on gmp.
9306 * m4/evalparse.c: New file, contains the shared parts of the
9307 eval() and evalmp() parser implementations, and is no longer
9308 unencumbered by cpp magic to uncover the right parts.
9309 * m4/numb.h: Removed. It's former contents are split between
9310 m4/eval.c and modules/mpeval.c.
9311 * m4/numb.c: ditto.
9313 * tests/other-tests/changeword.test: New test. Rudimentary
9314 testing of changeword builtin runs only if --wnable-changeword
9315 was used at configure time.
9316 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
9317 alternation correctly. Split into two expressions to compensate.
9318 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
9319 * modules/Makefile.am: Build changeword module.
9320 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
9321 only when --enable-changeword was passed to configure.
9322 (builtin_changeword): If --enable-changeword was not used, then
9323 report that changeword() builtin has no support in m4 binary.
9325 2000-11-28 Gary V. Vaughan <gary@gnu.org>
9327 * src/main.c (main): Fixed a particularly nasty bug is
9328 user_search_path setting -- the -M flag processing must be
9329 extremely careful with search path ordering, or else the default
9330 installed module directory (possibly containing modules from a
9331 previous release) is placed earlier in the search path than any -M
9332 arguments (which are relied upon to load uninstalled modules with
9333 most of the tests in the regresion suite).
9335 * modules/load.c (builtin_load): Nasty hack to prevent adding
9336 symbols to symtab again if a module is loaded more than once.
9337 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
9339 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
9340 possible NULL pointer dereference.
9342 * m4/module.c (m4_module_find_by_modname): Renamed from
9343 m4_module_modname_find. Fixed all references.
9344 (m4_module_find_by_builtin): New function.
9346 * modules/modfreeze.test: load the `load' module with each
9347 invocation.
9348 * src/freeze.c (produce_frozen_state): Simplified in light of
9349 module field in m4_symbol. Allow a third argument for text macros
9350 to name the originating module.
9351 (reload_frozen_state): ditto.
9352 * m4/m4module.h: Fixup prototypes.
9353 * m4/builtin.h (m4_builtin_define): Add a module argument so
9354 that symbols can be registered against the defining module.
9355 (m4_macro_define): ditto.
9356 * m4/m4private.h (m4_symbol): Make the module field const to save
9357 on casting in the rest of the code.
9358 (SYMBOL_MODULE): New macro.
9360 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
9361 symbol reference maintenance bugs when removing a symbol from the
9362 symtab.
9364 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
9366 2000-11-27 Gary V. Vaughan <gary@gnu.org>
9368 * configure.in (m4_cv_func_obstack): A better check for whether
9369 libc has an obstack implementation.
9370 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
9372 * configure.in (--with-modules): Changed semantics. This
9373 option is now used to list modules to be preopened.
9374 * src/m4.h: #include "ltdl.h" unconditionally.
9375 * src/main.c: Removed all dependencies on WITH_MODULES.
9376 * src/freeze.c: ditto.
9377 * modules/Makefile.am: ditto.
9378 * m4/m4.c (builtin_m4exit): ditto.
9379 * modules/modpath1.test: ditto.
9380 * modules/modpath2.test: ditto.
9381 * modules/modpath3.test: ditto.
9382 * modules/modpath4.test: ditto.
9383 * modules/modtest.test: ditto.
9384 * modules/shadow.test: ditto.
9385 * modules/unload.test: ditto.
9387 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
9388 comes up on demand in LTLIBOBJS now.
9389 * configure.in (getopt_long): Creating and relying on a link for
9390 getopt.h on hosts with no getopt_long() of thier own works
9391 correctly now. This is necessary so that callers of getopt_long()
9392 can simply `#include <getopt.h>': the naive way of doing this
9393 would end up using our own getopt.h and the installed
9394 getopt_long(), which is asking for trouble!
9395 (obstack_init): A similar argument applies to obstack.h and
9396 obstack_init().
9398 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
9399 On Solaris-2.5 (at least) the native dlopen implementation
9400 gets confused about m4.o when looking for module "m4". This
9401 version always looks for .la an .$lib_ext suffixed names first
9402 to work around the problem. Sigh.
9404 * po/POTFILES.in: Take account of these file movements.
9405 * src/Makefile.am (m4_SOURCES): removed eval.c.
9406 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
9407 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
9408 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
9409 * modules/m4.c (builtin_eval): Use m4_evaluate().
9410 * m4/eval.c: Moved here from src/eval.c to facilitate
9411 implementation of eval() builtin as part of the `m4' loadable
9412 module.
9413 (m4_evaluate): renamed from evaluate for namespace cleanliness.
9414 * m4/numb.c: Moved here from src/numb.c, since it is #included
9415 into eval.c at compile time.
9416 * m4/m4module.h (m4_evaluate): Added prototype.
9417 * src/m4.h (evaluate): Removed prototype.
9419 2000-11-25 Gary V. Vaughan <gary@gnu.org>
9421 * modules/perl.c (builtin_perleval): Use PL_na for
9422 compatibility with perl-5.6.
9424 * src/main.c (main): It is now safe to
9425 ``m4_module_install("m4")'', without tripping over the m4
9426 binary itself!
9427 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
9428 versions having fixed the insidious module search order bug.
9430 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
9431 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
9433 * configure.in: Figure out whether to use the installed
9434 getopt.h or the supplied one.
9435 * src/Makefile.am: ditto.
9437 * po/POTFILES.in: List files in their new positions.
9439 * config/ltmain.sh: This needs to be checked in to match the
9440 libtool macros copied to acinclude.m4 (until a released
9441 libtool copes with m4's needs).
9442 * bootstrap: Run gettextize.
9444 2000-11-24 Gary V. Vaughan <gary@gnu.org>

9490 * src/main.c (main): Load the traditional module if m4 was
9491 started in `no_gnu_extensions' mode.
9492 * modules/traditional.c: New file implementing the ``unix'' macro,
9493 required when m4 is executed in traditional mode, as a loadable
9494 module.

9506 the migration of all builtin implementations to loadable modules.
9507 * m4/macro.c: Moved this file here from the src directory,
9508 renaming all exported symbols to use the prefix ``m4_''.
9509 * m4/builtin.c: ditto.

9518 directory to facilitate builtin migration.
9520 2000-08-12 Gary V. Vaughan <gary@gnu.org>
9522 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
9523 error message, to make translators' jobs a little easier.

9553 makeinfo calculates them for us, and to make any future
9554 reorganisation easier.
9555 (Frozen files): Document format version 2.
9556 `V' now takes argument `2'.
9557 `F' can take a single argument if symbol and builtin names
9558 are the same, or 3 arguments if the builtin is from a module.
9559 New `S' specification for saving syntax table contents.
9560 New `M' specification for saving loaded module names.
9561 * src/freeze.c: Implement them.

9774 src dir and immediately after libm4 is built for confidence that
9775 it doesn't rely on the src directory.
9776 (SUBDIRS): Moved doc dir to the end since helptoman.pl and
9777 makeinfo stop the build on cygwin (because they don't work).
9779 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
9781 * m4/m4private.h: ...is not a public header, so moved to src.
9782 Add `#include <config.h>', `#define _COMPILING_M4' and
9783 `#include "m4.h".
9784 * m4/Makefile.am (noinst_HEADERS): remove m4private.h.
9785 * src/Makefile.am (noinst_HEADERS): add m4private.h.
9786 * src/builtin.c: `#include "m4private.h"' now takes care of the
9787 above. Duplicates removed.
9788 * src/debug.c: ditto.
9789 * src/eval.c: ditto.
9790 * src/evalmp.c: ditto.
9791 * src/format.c: ditto.
9792 * src/freeze.c: ditto.
9793 * src/input.c: ditto.
9794 * src/m4.c: ditto.
9795 * src/macro.c: ditto.
9796 * src/module.c: ditto.
9797 * src/numb.h: ditto.
9798 * src/output.c: ditto.
9799 * src/path.c: ditto.
9800 * stackovf.c: ditto.
9801 * symtab.c: ditto.
9803 * po/POTFILES.in: compensate for renaming of lib/*.
9804 * m4/Makefile.am (CLEANFILES): @EXEEXT@ left libtool wrapper behind.
9805 (INCLUDES): Look first in $(top_srcdir) (for eg. <m4/error.h>),
9806 and then in $(top_srcdir)/lib (for eg. "m4private.h").
9807 * src/Makefile.am (m4_LDADD): replace libi/libm4.la with
9808 m4/libm4.la.
9809 * m4/m4error.h: Renamed error.h, for installation to
9810 $prefix/include/m4..
9811 * m4/m4obstack.h: Renamed obstack.h, for same reason.
9812 * m4/m4regex.h: Renamed regex.h, for same reason.
9813 * m4/m4error.c: Renamed error.c, and use #include "error.h".
9814 * m4/m4obstack.c: Renamed obstack.c, and fix #includes.
9815 * m4/m4regex.c: Renamed regex.c, and fix #includes.
9817 * lib: moved to m4 to easily support header installation to
9818 $prefix/include/m4.

9825 From Akim Demaille <akim@epita.fr>
9827 2000-01-17 Gary V. Vaughan <gary@gnu.org>
9829 * src/ltdl.c: Use access() to abort doomed module load attempts
9830 if module file does not exist.
9832 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
9833 getopt1.o will already be used if appropriate, so I moved getopt.c
9834 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
9836 * modules/modpath1.test: Use correct filename in header line.
9837 * modules/modpath2.test: ditto.
9838 * modules/modpath3.test: ditto.
9839 * modules/modpath4.test: ditto.
9841 Without these changes lt_dlopen("test") attempts to
9842 LoadLibrary("/bin/test") on Windows, which although harmless
9843 generates a spurious error message which spoils most of the tests:
9844 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
9845 (TESTS): s/test.test /modtest.test /
9846 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /
9847 (test_la_SOURCES, test_la_LDFLAGS): renamed to use modtest.
9848 * modules/modpath1.test: s/test.m4 /modtest.m4 /
9849 * modules/modpath2.test: ditto.
9850 * modules/modpath4.test: ditto.
9851 * modules/modpath3.test: s/-m test /-m modtest /
9852 * modules/shadow.m4: use {un,}loadmodule(`modtest').
9854 2000-01-16 Gary V. Vaughan <gary@gnu.org>
9856 * src/ltdl.c (find_file): Updated to new version with fixed memory
9857 allocation bug in `next'.
9858 * src/ltdl.h: updated to match.
9860 * modules/Makefile.am: Cleaned up and reordered.
9862 2000-01-16 René Seindal <rene@seindal.dk>
9864 * modules/Makefile.am (TESTS): New tests for the module system.
9866 * modules/*.test: New files.
9868 * src/m4.c (main): Added call to module_init().
9869 Treats -M and -m as the arguments -D -U and -t, ie deferred.
9871 * src/m4.h: Added declaration of module_init().
9873 * src/module.c (module_init): No longer static
9875 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
9876 Added to shut up automake about non standard libtool library
9877 names.
9879 * src/module.c: Disabled DEBUG by default.
9881 * modules/README: Changed example from unload.m4 to shadow.m4
9883 * modules/shadow.m4: Renamed from unload.m4
9885 * modules/Makefile.am (EXTRA_DIST): Removed unload.m4.
9887 * src/m4.c (main): Functionality for -m and -M were reversed.
9888 Fixed.
9890 2000-01-12 Gary V. Vaughan <gary@gnu.org>
9892 * doc/help2man.pl: updated to version 1.020.
9894 * lib/COPYING.LIB: updated to version 2.1.
9896 * lib/m4module.h: restructure the M4_SCOPE code to work when
9897 creating a dll which links with libm4.la and both DLL_EXPORT
9898 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
9899 both defined.
9901 2000-01-11 Gary V. Vaughan <gary@gnu.org>
9903 Merged the following changes from my tree:
9905 1999-06-15 Gary V. Vaughan <gary@gnu.org>
9907 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
9908 ported to compile shared libs.
9910 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
9911 use `__declspec(dllimport)' when linking libm4.la on win32.
9912 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
9914 * configure.in (M4OBJS): Discover whether we need the shipped
9915 implementation of getopt_long.
9916 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
9917 main binary here, as opposed to the module library in lib/libm4.la.
9919 1999-06-14 Gary V. Vaughan <gary@gnu.org>
9921 * modules/README: Updated to describe the improved libltdl based
9922 module scheme.
9923 * README (cygwin): Added some compilation notes for building m4
9924 correctly under cygwin.
9925 * TODO: Cleaned out the entries for the module system since they
9926 are now implemented.
9928 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
9929 all instances of __P with M4_PARAMS.
9931 * lib/getdate.h: removed unreferenced file.
9933 * lib/m4private.h: New file to define the private interface to the
9934 token_data struct, which must be shared between m4module.c, and
9935 builtin.c but not exported to modules built from the installed
9936 m4module.h since it's size changes depending on compile time
9937 options.
9939 * src/m4.h: Lots of stuff moved to lib/m4module.h.
9941 * lib/m4module.h: New file to define the interface available when
9942 compiling m4 modules.
9943 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
9944 necessary for module compilation into this new file.
9946 * lib/Makefile.am (include_HEADERS): install headers (renamed to
9947 avoid nameclash with other system headers) necessary for compiling
9948 modules.
9949 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
9950 so that modules can include the (renamed) installed headers and
9951 be guaranteed a matching implementation.
9952 * lib/m4error.h: renamed from error.h.
9953 * lib/m4obstack.h: renamed from obstack.h.
9954 * lib/m4regex.h: renamed from regex.h.
9955 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
9956 implementation, simply include the shipped version
9957 unconditionally, otherwise it is hard for a module to know
9958 whether the m4obstack.h header it is using matches the
9959 implementation it ends up linking against.
9960 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
9961 the same reason.
9963 1999-05-18 Gary V. Vaughan <gary@gnu.org>
9965 * examples/misc.test: Don't run this test on machines which don't
9966 have a root user in /etc/passwd (e.g. cygwin).
9968 * tests/get-them (/^@example$/): Error messages might have a
9969 ``.exe'' suffix to the program name, or else use the libtool
9970 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
9971 of these cases are now catered for when comparing error messages
9972 in generated tests.
9973 * tests/other-tests/*.test: ditto.
9974 * examples/*.test: ditto.
9976 * tests/defs (M4): use libtool execute mode.
9977 * examples/defs (M4): ditto.
9979 * tests/get-them (END): explicitly close any open file.
9980 (printthem): In a regular expression, '{' is the start of a repeat
9981 count! Use `[{]' for a literal open brace.
9982 (/^@node /): Don't use substr on a string shorter than the trim
9983 length.
9985 1999-05-17 Gary V. Vaughan <gary@gnu.org>
9987 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
9988 substituted.
9989 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
9991 2000-01-10 Andreas Schwab <schwab@suse.de>
9993 * tests/other-tests/gmp.test: Find config.sh in build directory.
9995 * configure.in: Find tests/mkconfig.sh in $srcdir.
9997 * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in
9998 <signal.h> (for SUS2 compliant systems).
10000 * src/stackovf.c: Check for HAVE_SIGINFO_T in addition to
10001 HAVE_SIGINFO_H.
10003 2000-01-10 René Seindal <rene@seindal.dk>
10005 * Prerelease 1.4o.
10007 * TODO, NEWS: Cleaned up and updated.
10009 * src/m4.c (main): New variable exit_status for exit status in
10010 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
10011 file cannot be read instead of EXIT_SUCCESS.
10013 * src/builtin.c (m4_indir): Changed error message to help
10014 translators (from Akim Demaille <demaille@inf.enst.fr>).
10016 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
10017 Cygnus.
10019 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
10020 from glic 2.1.2.
10022 * src/input.c (match_input): Reordering of code, to avoid multiple
10023 calls to push_string_init() from obstack_grow(), which can happen
10024 with some compilers (found and fixed by James Bonfield
10025 <jkb@mrc-lmb.cam.ac.uk>).
10027 * src/stackovf.c: Added prototypes for ultrix.
10028 (setup_stackovf_trap): Added __P to cast.
10029 (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>)
10031 2000-01-09 René Seindal <rene@seindal.dk>
10033 * doc/m4.texinfo (Changequote): Added comment about changing
10034 quotes when the old quote is a part of the new.
10036 * src/builtin.c (expand_ranges): Added break after trailing dash.
10037 This caused misbehavious on some systems (found and fixed by Akim
10038 Demaille <demaille@inf.enst.fr>).
10040 * AUTHORS: Thomas Tanner included
10042 * acconfig.h: Added entry for ss_sp (see below).
10044 * configure.in (use_stackovf): Added check for stack_t with member
10045 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert
10046 <eggert@twinsun.com>).
10048 * doc/m4.texinfo (Frozen files): Added a simpler example for
10049 generating frozen files from several input files.
10051 1999-11-14 Paul Eggert <eggert@twinsun.com>
10053 * po/POTFILES.in: Add lib/getopt.c, lib/obstack.c,
10054 lib/regex.c, lib/xmalloc.c.
10056 1999-11-10 René Seindal <rene@seindal.dk>
10058 * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal.
10060 * src/module.c: reindented.
10061 (module_load): return if this is a repeated load of same module.
10062 (module_init): slight change of logic to avoid repeated
10063 initialisation debug messages.
10065 * Makefile.am (DIST_SUBDIRS): Added to ensure modules/ is included
10066 in the distribution.
10068 * modules/Makefile.am (test_la_LDFLAGS): set to -module to silence
10069 automake warnings about missing lib prefix.
10070 (time_la_LDFLAGS): ditto
10071 (stdlib_la_LDFLAGS): ditto
10073 1999-11-10 Paul Eggert <eggert@twinsun.com>
10075 * src/m4.h: Include error.h, since our macros use error.
10076 * src/m4.c: Don't need to include error.h.
10078 1999-11-09 Paul Eggert <eggert@twinsun.com>
10080 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
10081 and zero, as Solaris 7 cc does.
10082 (bcopy): Remove macro; no longer needed with new obstack.h.
10084 * src/output.c (freeze_diversions): Don't assume that a
10085 diversion size can fit in `int'. Check for diversion file
10086 size too large to be printed with `unsigned long'.
10088 * src/Makefile.am (CFLAGS): Omit -Wall.
10090 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.
10092 * src/debug.c (trace_format):
10093 Use ANSI C if (defined __STDC__ && __STDC__) || defined PROTOTYPES.
10095 * src/freeze.c (produce_frozen_state):
10096 Don't assume string lengths fit in int.
10098 1999-10-13 René Seindal <rene@seindal.dk>
10100 * po/cs.po: Czech translation added.
10102 * po/sv.po: Updated Swedish translation.
10104 * po/ru.po: Updated Russian translation.
10106 * po/pl.po: Updated Polish translation.

10112 * configure.in (ALL_LINGUAS): Added Greek translation (el).
10113 (ALL_LINGUAS): Added Czech translation (cs).
10115 1999-03-30 Gary V. Vaughan <gary@gnu.org>
10117 * src/builtin.c: moved module loading functions into...
10118 * src/module.c: entirely new implementation using libltdl.
10119 * po/POTFILES.in: added src/module.c.
10120 * modules/Makefile.am (LTLIBRARIES): Removed lib prefix as these
10121 are modules, not linktime libraries.
10122 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
10123 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
10124 avoidance on exported symbols.
10125 * modules/test.c (m4_macro_table, m4_init_module,
10126 m4_finish_module): ditto.
10127 * modules/time.c (m4_macro_table): ditto.
10129 * modules/time2.m4: new file which requires command line loading
10130 of modules.
10131 * src/m4.c (--load-module): dynamically load named runtime module
10132 into running executable before reading the source.
10133 (--module-directory): prepend a directory to the module search
10134 path.
10135 (module_init()): Do this the first time we load a module instead;
10136 if the module subsystem is broken normal m4 scripts can still run.
10137 * src/m4.h (install_builtin_table): is now exported.
10139 1999-03-26 Gary V. Vaughan <gary@gnu.org>
10141 * src/module.c: removed. No longer required.
10142 * po/POTFILES.in: removed src/module.c.

10147 * doc/Makefile.am (MAINTAINERCLEANFILES): ditto.
10148 * examples/Makefile.am (MAINTAINERCLEANFILES): ditto.

10152 * src/Makefile.am (MAINTAINERCLEANFILES): ditto.
10153 * tests/Makefile.am (MAINTAINERCLEANFILES): ditto.
10155 * acinclude.m4: removed. `aclocal -I acm4' handles this much
10156 better.
10157 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
10158 * acm4/gettext.m4: removed. It causes a multiple definition vs.
10159 the installed gettext.m4 file when running aclocal.
10161 1999-03-25 Gary V. Vaughan <gary@gnu.org>
10163 * configure.in (AM_INIT_AUTOMAKE): bumped version number to
10164 distinguish this from the last prerelease.
10165 (AC_LIBLTDL_CONVENIENCE): build libltdl as a convenience library
10166 in its own subdirectory.
10168 * modules/Makefile.am (*_SOURCES): renamed to use libtool's "no
10169 lib prefix on a module" feature.
10170 (LDFLAGS): Added `-module -avoid-version' flags to build
10171 versionless module libraries.
10172 * src/builtin.c (m4_load_module): use libltdl.
10173 (module_unload_all): use libltdl.
10174 * src/m4.c (module_init): initialise module loading on demand for
10175 better diagnostics, and so that m4 will still work even if
10176 the module code is broken.
10177 * src/m4.h (module_init): removed. No longer relevant.
10178 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on
10179 exported symbols for compatibility with dlpreopening.
10180 * modules/test.c (m4_macro_table, m4_init_module,
10181 m4_finish_module): ditto.
10182 * modules/time.c (m4_macro_table): ditto.
10184 * bootstrap: New file. Runs all the autoutils in the right order
10185 after a fresh checkout, or a make maintainer-clean.
10187 1999-02-18 Akim Demaille <demaille@inf.enst.fr>
10189 * src/builtin.c (dump_symbols): New function, factoring common
10190 content of m4_dumpdef and m4_symbols.
10191 (m4_dumpdef): Use it.
10192 (m4_symbols): New function, implementing `symbols'. Use it.
10193 * doc/m4.texinfo: Fixed missing commas after @xref, so that the
10194 file compile with modern makeinfo.
10195 (Symbols): New node, documenting symbols.
10196 (direntry): Modernize.
10198 1998-12-11 René Seindal <rene@seindal.dk>
10200 * src/builtin.c (predefined_tab): New predefined macros
10201 __m4_changeword__, __m4_gmp__ and __m4_modules__ for testing for
10202 configure time options.
10204 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
10206 * src/module.c (module_try_load): Don't try to be clever and
10207 overwrite argument string. Instead allocate all constructed
10208 strings locally, since they can have arbitrary lengths. Make
10209 arguments pointers to const.
10210 (module_search): Simplify due to above change.
10212 1998-11-29 René Seindal <rene@seindal.dk>
10214 * Prerelease 1.4n.
10216 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): New tests.
10218 * tests/other-tests/import-environment.{m4,test}: New test.
10220 * tests/other-tests/discard-comments.{m4,test}: New test.
10222 * doc/m4.texinfo (Invoking m4): Updated for --discard-comments.
10224 * src/m4.c (main): New option -c --discard-comments.
10225 New global variable discard_comments.
10227 * src/m4.h (token_type): New TOKEN_NONE for tokens to be
10228 discarded, ie never returned from next_token().
10229 Added declaration of discard_comments.
10231 * src/input.c (next_token): Now loops until token type is not
10232 TOKEN_NONE. Comments are now given this type when comments should
10233 be discarded.
10235 * doc/m4.texinfo (Invoking m4): Updated for --import-environment
10236 and mpeval.
10238 1998-11-28 René Seindal <rene@seindal.dk>
10240 * src/m4.c (main): New option --import-environment (no single
10241 letter option).
10243 * When configured with --with-gmp both the normal (fast) eval()
10244 and the gmp aware mpeval() are defined. To restore previous
10245 bahaviour use "define(`eval', defn(`mpeval'))".
10247 * tests/other-tests/gmp.m4: Changed to use mpeval().
10249 * src/evalmp.c: New file for compiling eval.c as gmp aware.
10250 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
10252 * src/eval.c: Now includes "numb.c" directly. Everything in this
10253 file must by static, except evaluate(), which is changed to
10254 mp_evaluate() if USE_GMP in force.
10256 * src/numb.c: Changed to be included by eval.c instead of being
10257 compiled separately. Everything is declared static.
10259 * src/numb.h: Removed declarations of functions, as numb.c is now
10260 included by eval.c.
10262 * src/builtin.c: Declaration of m4_mpeval() added.
10263 Inserted `mpeval' in builtin table.
10264 (do_eval): New function with common code for m4_eval and m4_mpeval.
10265 (m4_mpeval): New function for gmp version of eval.
10267 * src/m4.h: Declaration of mp_evaluate().
10269 * src/Makefile.am (m4_SOUCES): Includes mpeval.c.
10270 (EXTRA_m4_SOURCES): Now has numb.c and numb.h
10272 * src/m4.c (main): m4 --version also shows which options were used
10273 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
10275 1998-11-27 René Seindal <rene@seindal.dk>
10277 * Error messages now always print program name before input file
10278 name as specified by GNU coding standards. Reported by Akim
10279 Demaille <demaille@inf.enst.fr>.
10281 * doc/m4.texinfo (Include): Change due to changed error message
10282 format.
10283 (Eval): Do.

10286 message format.
10288 * src/m4.c (print_program_name): New func used to print program
10289 name, input file and line number in error (). Used as an
10290 error_print_progname handler.

10298 * Updated to libtool 1.2b.
10300 * src/builtin.c (install_builtin_table): Added braces to avoid
10301 warning of ambiguous 'else'.
10303 * src/module.c: Inserted search path code from path.c modified to
10304 use new interface.
10305 (module_init): Configured default path used only if M4MODPATH is
10306 not set.
10307 (module_try_load): Now reads libMODULE.la as generated by libtool
10308 for actual module name.

10315 functions of more generic search path handling.
10317 1998-11-24 René Seindal <rene@seindal.dk>
10319 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
10320 included gettext, as <libintl.h> might not be found
10321 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
10323 1998-11-22 René Seindal <rene@seindal.dk>
10325 * src/output.c (insert_diversion): Fixed bug that might cause m4
10326 to read from standard output! Triggered by input
10327 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
10328 so now 'undivert(0)' does nothing.
10330 1998-11-18 René Seindal <rene@seindal.dk>
10332 * Prerelease 1.4m.
10334 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
10335 could be changed when compiling a illegal regexp, causing later
10336 use of the regexp to dump core.

10351 * acm4/modules.m4 (AM_WITH_MODULES): Redone completely to work
10352 with libtool.
10354 * modules/Makefile.am: Changed completely to compile modules using
10355 libtool. The modules are compiled as shared libraries, and are
10356 renamed when installed.
10358 * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
10359 USE_SHL_LOAD to HAVE_SHL_LOAD

10363 * src/module.c: New level of indirection around non-portable
10364 functions to load shared objects. Intended to encapsulate the non
10365 portable parts better and to reduce the number of #ifdefs in the
10366 code.
10368 * Makefile.am (DIST_SUBDIRS): Instead of EXTRA_DIST for added
10369 directory modules/ to the distribution.
10371 1998-11-15 René Seindal <rene@seindal.dk>

10385 * Makefile.am (SUBDIRS): Directory modules added if configured.
10387 * modules/Makefile.am: Now correctly compiles and installs
10388 modules in pkglibexecdir.
10390 * src/m4.h: WITH_MODULES defined iff HAVE_DLOPEN or USE_SHL_LOAD.
10391 These two are now initialised by autoconf macros.
10393 * src/path.c (module_env_init): MODULE_PATH is always on the
10394 search path.
10396 * src/Makefile.am: Now generated pathconf.h which defined the
10397 default MODULE_PATH.
10399 * configure.in (pkglibexecdir): Added defintion of pkglibexecdir,
10400 where modules are installed.
10402 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
10403 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
10404 build and install automatically, and it is prepared for other
10405 interfacec than dlopen().
10407 * src/builtin.c (predefined_tab): Added __m4_version__ for the
10408 current version of GNU m4. It is a GNU extension.
10410 1998-11-14 René Seindal <rene@seindal.dk>
10412 * tests/Makefile.am (GENERATED_TESTS): Added new
10413 generated-tests/changesy.8.test

10425 iff some character has code SYNTAX_ESCAPE
10426 (input_init): Added initialisation of use_macro_escape.
10427 (check_use_macro_escape): New function to synchronise
10428 use_macro_escape with the syntax table.
10429 (set_quotes): Added call to check_use_macro_escape()

10441 generated-tests.
10443 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): Added manually
10444 maintained tests in tests/other-tests. These currently tests for
10445 8-bit transparency, multiple precision arithmetic and sync-line
10446 output. Test for stackoverflow detection does not work.
10448 * examples/Makefile.am (TESTS): Added tests for all example files.
10450 * examples/mktests.sh: New file. Help program for creating test
10451 files.

10458 * src/path.c (path_search): Added argument 'char **expanded_name'
10459 to return the expanded name.
10461 * src/m4.h: Added 2nd argument to declaration of path_search().
10463 * src/m4.c (main): Added 2nd argument to path_search().

10488 1998-10-07 René Seindal <rene@seindal.dk>
10490 * Prerelease 1.4j.
10492 * tests/Makefile.am (GENERATED_TESTS): Changed .m4 extension to
10493 .test, as the files are no longer just m4 input.
10495 * tests/get-them (FILE): Changed .m4 extension to .test.
10497 * src/m4.h (token_type): New token type TOKEN_SPACE introduced.
10498 Otherwise quoted strings with leading whitespace first in a macro
10499 argument would be eliminated.
10501 * src/macro.c (expand_token): Handles new token type TOKEN_SPACE.
10502 (expand_argument): Do.
10504 * src/input.c (next_token): SPACE and NUM/OTHER characters are only
10505 grouped together iff both quote and comment strings are single
10506 character. Otherwise they might include a comment/quote leader.
10507 (next_token): Returns new token type TOKEN_SPACE.
10509 * src/builtin.c (push_builtin_table): New function to push a
10510 builtin_table on the stack without installing its contents.
10511 (find_builtin_by_name): Added call to push_builtin_table() if
10512 reading frozen files. Otherwise the builtins named in the frozen

10534 dynamic module loading.
10536 * src/Makefile.am (m4_SOURCES): Added module.c
10538 * src/builtin.h: New file, declares some functions from builtin.c
10539 that are of use for other modules (shipout_int, numeric_arg,
10540 skip_space, bad_argc), and the macros ARG() and DECLARE().
10542 * src/builtin.c (install_builtin_table): New function. Each
10543 module brings in a builtin_table, which is pushed on a stack.
10544 (struct builtin_table): New struct for list of builtin_tables.
10545 (m4_loadmodule): New function to implement builtin "loadmodule".
10546 (shipout_int): No longer static, to be used by modules.

10557 * src/m4.h: Added declarations for new functions in module.c and
10558 in path.c.
10560 * src/m4.c (main): Added call to module_init().
10562 * modules: New directory with a few demo modules.
10564 * Makefile.am (EXTRA_DIST): Added modules/* since modules/ is not
10565 in SUBDIRS.
10567 * configure.in: Added modules/Makefile to AC_OUTPUT.
10569 * configure.in: Added code to implement --with-modules. Tests for
10570 <dlfcn.h> and -ldl.
10572 * acconfig.h: Added WITH_MODULES
10574 1998-10-02 René Seindal <rene@seindal.dk>
10576 * examples/Makefile.am (pkgdata_DATA): Removed special target for
10577 check and variables TESTS. These tests are now run from the
10578 tests/ directory.
10580 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
10581 directory. The files stay there but the tests are run from the
10582 tests/ directory.
10584 * tests/Makefile.am (EXTRA_DIST): Added run-test.
10586 * tests/run-test: New file. Run a test manually
10588 * tests/Makefile.am, tests/get_them: Moved automatically generated
10589 tests (from the manual) to sub directory tests/gentest/. The
10590 tests/ directory had gotten a bit messy.
10592 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10594 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\
10595 wrap}.test: Added a few testcases.
10597 1998-08-21 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10599 * Prerelease 1.4h.
10601 * lib/Makefile.am (noinst_HEADERS): regex.h added
10603 * configure.in (jm_WITH_REGEX, jm_PREREQ_ERROR):
10604 acm4/{error,regex}.m4 (from fileutils-3.16u.tar.gz).
10606 * acm4/Makefile.am: created providing rules to create
10607 $(top_srcdir)/acinclude.m4 to be used by aclocal.
10609 * tests/defs (LANGUAGE, LC_ALL, LANG): force them to be
10610 `C'. Reported by Ulrich Drepper.
10612 * Makefile.am (SUBDIRS): Removed checks directory
10613 * configure.in (AC_OUTPUT): Removed checks/Makefile
10615 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
10616 the space when m4.texinfo is edited and whitespace.el is active.
10617 (Defn,example): idem.
10619 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10621 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
10622 ../COPYING. ../Makefile is a file which is certainly present when
10623 test is executed in testSubDir. One can't be sure that the COPYING
10624 file is in .. or ../.. in all situations, the ../Makefile is
10625 always there.
10627 * doc/m4.texinfo (Include): adjusted expected test output
10628 according to new tests, i.e. the input will always come from the
10629 file `in' created by the test.
10631 * tests/Makefile.am: Added three lines at the top to get
10632 esyscmd.1.test working.
10634 * tests/get-them: modified to generate clearer tests who will need
10635 less maintenance when new test examples are created in
10636 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
10637 need the generic file `defs') shell scripts creating `in', `ok',
10638 `out' and when apropriate `okerr' and `err' in the directory
10639 `testSubDir' when executed. The compare of `ok' and `out'
10640 (and of `okerr' and `err') will be the exit status of the test.
10641 `out' must match `ok' (and `okerr' must match `err') for the test
10642 to be succesful.
10644 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
10645 the tests generated by tests/get-them getting it input normally
10646 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
10647 (dot) before the numeric part) is reserved for all other (hand
10648 written) tests. The `+' means one or more times.
10650 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10652 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
10653 supported short man page to refer to info documentation
10654 * helptoman.pl: added
10655 * configure.in: AC_PATH_PROG(PERL,perl)
10656 * Makefile.am (SUBDIRS): doc after src
10658 * libitized with libit 0.5 from
10659 ftp://ftp.iro.umontreal.ca/pub/contrib/pinard/maintenance/libit.

10666 * configure.in (AC_CHECK_FUNC): getopt_long
10668 * src/m4.c (usage): Report bugs to m4-bugs@gnu.org.
10670 * TODO: added entry about dependencies
10672 1998-08-10 René Seindal <rene@seindal.dk>
10674 * Prerelease 1.4f
10676 * doc/m4.texinfo (Changesyntax): Added documentation for the macro
10677 "changesyntax".
10679 * src/builtin.c (m4_changesyntax): Added builtin macro
10680 "changesyntax" to modify the syntax table.
10682 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax
10683 table. All categories are assigned a syntax code and tokens are
10684 read according to this table.
10686 1998-08-09 René Seindal <rene@seindal.dk>
10688 * src/numb.{c,h}: New files, implements multiple precision eval
10689 using GNU gmp. Originally submitted by John Gerard Makecki
10690 (johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.
10692 * doc/m4.texinfo (Eval): Added documentation for multiple
10693 precision arithmetic library support.
10695 * src/m4.{c,h}, src/eval.c, src/builtin.c, configure.in: Changes
10696 to accommodate multiple precision eval.
10698 1998-08-07 René Seindal <rene@seindal.dk>
10700 * src/input.c (MATCH, match_input), src/m4.h: changed definition
10701 of comment and quote strings to `unsigned int' to allow eight bit
10702 chars (reported by andrewb@zip.com.au (Andrew Bettison)).
10704 * src/builtin.c, doc/m4.texinfo: Builtin `syncoutput' added by
10705 patch from Mike Howard <mike@clove.com>
10707 1998-08-06 René Seindal <rene@seindal.dk>
10709 * gettext.m4: corrected AM_WITH_NLS to handle use of installed

10720 to look for right message catalogs. Call indef'ed by ENABLE_NLS.
10722 * configure.in (ALL_LINGUAS): Added complete list of translations:
10723 de fr it ja nl ru sv.
10725 1998-05-23 Erick Branderhorst <Erick.Branderhorst@asml.nl>
10727 * po/nl.po: Dutch translation by Erick Branderhorst.

10752 README accordingly.
10754 * src/stackovf.c: #ifdef USE_STACKOVF ... #endif to (de-)activate
10755 stack overflow functionality.

10834 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
10835 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
10836 defines __STDC__ to 0, for indicating it is *not* ANSI!
10837 Reported by Kaveh R. Ghazi.

10854 * src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
10855 Remove the sed filter after ansi2knr for debug.c. Use $O instead
10856 of $U, put underline in extensions rather than in basenames. Use
10857 implicit rules, now that regularity makes this possible.
10858 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
10859 of ansi2knr whenever it is needed.
10860 * configure.in: Adjusted for correct STACKOVF substitution.
10861 * src/debug.c (trace_format): When not __STDC__, use (...) as a
10862 parameter list, so ansi2knr will convert it to (va_alist) va_dcl.

10952 * Release 1.3.
10954 * Makefile.in: Group all *clean-recursive goals in one, using sed
10955 to remove `-recursive' while calling make recursively. Also, use
10956 a subshell for each recursive $(MAKE).

10959 * src/m4.h (memcpy): Define with bcopy for BSD systems.
10960 Reported by Kaveh R. Ghazi.
10962 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS

11020 Solidify frozen files with respect to -P:
11021 * src/m4.c: Have -P set prefix_all_buitins variable instead of
11022 calling a function by that name. Declare the variable.

11024 * src/builtin.c (builtin_init): Merge in functionality from
11025 previous prefix_all_buitins function, while making entries in the
11026 symbol table, but not modifying the builtin description itself.
11028 * src/freeze.c (reload_frozen_state): Add a useless `break;',
11029 because *many* compilers do not accept an empty `default:'.

11038 m4 in the src directory.
11039 * Makefile.in (check): Don't.
11040 Reported by Akiko Matsushita and Jim Meyering.
11042 * src/output.c (make_room_for, output_character_helper): New

11044 a per buffer MAXIMUM_BUFFER_SIZE.
11046 * src/output.c (output_text): New function, for optimizing the
11047 output of strings of characters. Use it.

11098 (shipout_text, make_diversion, insert_diversion): Adapted to new
11099 structures.
11100 (insert_file): Use better buffering.
11101 Reported by David MacKenzie.
11103 1994-08-28 François Pinard <pinard@iro.umontreal.ca>
11105 * Makefile.in, lib/Makefile.in, checks/Makefile.in: Arrange so
11106 dist works from another build directory.
11108 1994-08-27 François Pinard <pinard@iro.umontreal.ca>
11110 * symtab.c (hack_all_symbols): Use hash_table_size instead of

11116 * Makefile.in: Compile it, distribute it.
11117 * m4.c: Recognize, document and process --freeze-state (-F) and

11207 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
11208 error message, for when no code possibility exists. Even if this

11210 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
11212 * Makefile.in (install): Have install depend on all too, for lib
11213 to be remade as needed.

11222 this way, a change in lib will be detected and processed.
11224 * builtin.c (numeric_arg): Use strtol and verify the conversion,
11225 instead of using sscanf which stops as soon as there is a
11226 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
11227 and divert(1xyzzy) were all accepted without any warning or error
11228 messages.
11229 * m4.h: Declare strtol as long if not including stdlib.h.
11230 * configure.in: Check for limits.h, and replace strtol if missing.

11244 1994-07-06 Jim Avera <jima@netcom.com>
11246 * stackovf.c: Isolated OS-dependent sections; Improved portability,
11247 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
11248 handlers), and a default error message if the fault address is not
11249 available (when neither siginfo.h nor BSD sigcontext are supported).
11250 * configure.in: Changes for stackovf.h: Check for sigcontext,
11251 sigaction, sigstack, and define rlim_t as int if necessary.
11252 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
11253 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.

11256 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
11258 * configure.in: Use AC_SET_MAKE.
11259 * Makefile.in: Use @SET_MAKE@.

11267 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
11268 because siginfo.h is unrelated to standard headers, and siginfo.h
11269 is already checked for.
11270 Reported by Joseph E. Sacco.
11272 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
11273 PROTOTYPES.
11274 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
11275 AC_PROTOTYPES.
11277 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
11279 * builtin.c (substitute): Use \& to represent this part of the
11280 string which was matched by the whole regexp, instead of
11281 representing the whole string. Any usage of \0 issues a warning
11282 and acts like \&, it will disappear in some subsequent release.
11284 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
11286 * m4.c: Complete prototype for forwarded declaration of usage.
11288 * input.c (init_macro_token): Correct own reference in error
11289 message. Previous name get_macro_func was referred to instead.
11290 (next_char): Correct own reference in error message. Previous
11291 name advance_input was referred to instead.
11293 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
11294 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
11295 and_term, not_term, logical_not_term, cmp_term, shift_term,
11296 add_term, mult_term, exp_term, unary_term, simple_term): Add
11297 prototype to forwarded declarations. Declare parameter v1 as
11298 eval_t * instead of int *. Same for local variable v2 in dyadic
11299 functions. Same for result in exp_term.
11300 * builtin.c (m4_eval): Declare value as eval_t instead of int.
11301 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
11302 unsigned_eval_t instead of unsigned int. Change casts accordingly.
11303 (shipout_int): Cast first argument of ntoa to eval_t.
11304 Reported by Thorsten Ohl.
11306 * macro.c: Complete the prototypes of forwarded expand_macro and
11307 expand_token.
11308 Reported by Thorsten Ohl.
11310 * m4.h: Define voidstar as void * or char * depending on __STDC__.
11311 The Ultrix 3.1 compiler cannot do much with void pointers.
11313 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
11314 * m4.c (xfree): Replace void * by voidstar.
11315 Reported by Tom McConnell.

11318 * Makefile.in (DISTFILES): Distribute ansi2knr.1
11320 * Makefile.in (stamp-h.in): Avoid running ./config.status if
11321 stamp-h does not exist yet. This avoids running it a second time
11322 just after the initial ./configure.
11323 Reported by David MacKenzie and Tom McConnell.
11325 * m4.h: Replace the enum debug_info declaration with a series of
11326 #define's. The Ultrix 3.1 compiler would otherwise need casting
11327 (int) to most references, when used in expressions.
11328 Reported by Tom McConnell.
11330 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
11332 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
11333 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
11334 calls the compiler. Previously, FP_PROTOTYPES was only calling
11335 the preprocessor; by not being subject to CFLAGS, this was
11336 discouraging those flags asking for ANSI compilation.
11337 * acconfig.h: Document HAVE_PROTOTYPES.
11338 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
11339 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
11340 Reported by Eric Backus.
11342 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
11343 from the environment. Default CFLAGS to -g if not set.
11344 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
11345 * lib/Makefile.in: Have CFLAGS substituted from configure.
11346 Reported by Eric Backus and Tom McConnell.
11348 * configure.in: m4_undefine changeword before using AC_ENABLE.
11350 * m4.h: Declare prototypes for error (for ANSI compilers only),
11351 prefix_all_builtins and reference_error.
11352 Reported by Tom McConnell.
11354 * input.c (set_word_regexp): Do not try to initialize the array
11355 test from a string, this does not work with non-ANSI compilers.
11356 Reported by Eric Backus.
11358 * Makefile.in (dist): Clean examples/ before saving it.
11359 (distclean-local): Also remove stamp-h.
11360 Reported by Eric Backus.
11362 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
11363 non ANSI compilers.
11364 Reported by Tom McConnell.
11366 * checks/Makefile.in (clean): Depends on mostlyclean.
11367 (mostlyclean): New goal.
11369 1994-06-24 François Pinard <pinard@iro.umontreal.ca>
11371 * Makefile.in (DISTFILES): Distribute install.sh.

11377 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
11378 * acconfig.h: Explain ENABLE_CHANGEWORD.
11380 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
11381 from code provided by Pete Chown]
11382 * m4.h: Add original_text field to u_t variant of union u.
11383 Declare TOKEN_DATA_FUNC macro.
11384 * builtin.c: Declare changeword.
11385 (m4_changeword): New function.
11386 * input.c: Include "regex.h", define variables with word regexps.
11387 (input_init): Initialize the word regexp.
11388 (set_word_regexp): New.
11389 (next_token): Declare local variables, use the previous code if
11390 default_word_regexp is true. Else, match using a new code. Save
11391 the original text.
11392 * macro.c (expand_token): Ship out original text if not a macro
11393 name.
11394 Reported by Krste Asanovic and Pete Chown.
11396 [These modifs all depend upon ENABLE_CHANGEWORD]
11397 * m4.h: Declare external user_word_regexp.
11398 * m4.c: Declare user_word_regexp, and initialize it from
11399 --word-regexp or -W, or NULL if not specified.
11400 * input.c: Use user_word_regexp if specified, instead of
11401 DEFAULT_WORD_REGEXP.
11403 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
11404 agree with it.
11406 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
11407 * checks/Makefile.in: Empty the suffix list.
11408 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
11410 * m4.c: Declare nesting_limit and initialize it to 250.
11411 Implement -LNUMBER or --nesting-limit=NUMBER to change its
11412 value.
11413 * m4.h: Declare nesting_limit as external.
11414 * macro.c (expand_macro): Stop execution whenever nesting limit
11415 is exceeded.
11416 Reported by Bengt Mertensson.
11418 * eval.c (evaluate): Diagnose excess characters in eval input.
11419 Things like `eval(08)' used to return 0 with no diagnostic.
11421 * m4.h: Capitalize first letter of all macro arguments in
11422 definitions.
11424 * m4.c: Declare warning_status, initialize it to 0. Add new
11425 option -E, or --fatal-warnings, which sets warning_status to
11426 EXIT_FAILURE instead.
11427 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
11428 EXIT_FAILURE if not otherwise done by header files.
11429 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
11430 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
11431 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first
11432 argument of all M4ERROR calls.
11433 Reported by Noah Friedman.
11435 * examples/incl-test.m4: Renamed from incl_test.m4.
11436 * examples/include.m4: Include incl-test.m4 instead of
11437 incl_test.m4.
11438 * examples/multiquotes.m4: Renamed from multi-quotes.m.
11440 1994-06-22 François Pinard <pinard@iro.umontreal.ca>
11442 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
11443 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
11444 also tested it on a Sun Sparc workstation running SunOS 4.x.
11446 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
11447 49.format check, abusing a `union values' argument with sprintf
11448 without selecting the proper field. Now, save the formatting type
11449 first, delaying the fetch of the corresponding argument.
11450 Reported by Joseph E. Sacco and Tom Quinn.
11452 * format.c (format): Remove const from char *fmt declaration when
11453 not HAVE_EFGCVT, because a NUL may be forced into it.
11455 * m4.h: Declare atof() when not STDC_HEADERS.
11456 Reported by Joseph E. Sacco.
11458 * Regenerate configure using Autoconf 1.11, this corrects a
11459 problem about an incorrect cpp seting on NeXT 3.1.
11460 Reported by Alexander Lehmann.
11462 1994-06-05 François Pinard <pinard@iro.umontreal.ca>
11464 * m4.h (_): Change argument from `x' to `Args'.

11473 * stackovf.c: New file implementing stack-overflow detection.
11474 * configure.in: Check for getrlimit, sigaction. If all of
11475 standard headers, getrlimit and sigaction, define USE_STACKOVF and
11476 substitute ${U}stackovf.o for STACKOVF.
11477 * acconfig.h: Declare USE_STACKOVF.
11478 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
11479 * m4.h: Declare setup_stackovf_trap().
11480 * m4.c: Call setup_stackovf_trap().
11481 * tests/stackovf_test.sh: New file.
11483 1994-04-13 François Pinard <pinard@iro.umontreal.ca>
11485 * checks/Makefile.in: Rename .all-stamp to stamp-checks.
11487 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8.
11489 1994-01-30 François Pinard <pinard@iro.umontreal.ca>
11491 * m4.h: Remove definition of volatile, not used anymore.
11492 Reported by Jim Meyering and Joseph E. Sacco.
11494 * m4.h: Consistently use `do { ... } while (0)' in macros, instead
11495 of `if ... else /* nothing */' for if macros.
11496 Reported by Jim Meyering.
11498 * builtin.c (m4_regexp): Reorganize the code for avoiding a
11499 warning from gcc about `repl' possibly used before defined.
11500 Reported by Jim Meyering.
11502 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
11503 Reported by Jim Meyering.
11505 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
11507 * m4.h: Move the conditional definition of volatile after the
11508 inclusion of system files, because they may define it first.
11510 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
11512 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
11513 get around a problem with Alpha make seeing a syntax error, there.
11514 Reported by Vern Paxson.
11516 1994-01-03 François Pinard <pinard@iro.umontreal.ca>
11518 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.
11519 Reported by Richard Stallman.
11521 1993-12-25 François Pinard <pinard@iro.umontreal.ca>

11529 * m4.c: Initialize show_help and show_version to zero.
11531 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined.
11532 Use them in exit() and usage() calls.
11534 1993-11-27 François Pinard <pinard@iro.umontreal.ca>
11536 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
11537 syserr() macro. Delete errref, add reference_error and M4ERROR.
11538 * m4.c: Replace errref, which was returning an input reference
11539 string, with reference_error, which prints it on standard error.
11540 * builtin.c, output.c: Use errno as second parameter to error,
11541 instead of using syserr() with %s.
11542 * *.c: Use M4ERROR instead of error: no more errref() with %s.
11543 Doing so, the program name appears after the input reference
11544 instead of before, which eases M-x next-error processing.
11546 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
11548 * checks/get-them: Escape braces with backslashes in patterns,
11549 because HPUX-9.01 awk needs this.

11558 Declare xrealloc, for use in errref().
11559 * m4.c: Delete error_message_prefix() function, add errref().
11560 * *.c: Use error() systematically in place of all error macros,
11561 now that error() flushes stdout first. Make needed adjustments.
11563 * m4.h: Remove const in sys_errlist[] declaration, it creates
11564 conflicts on SGI and Alpha.
11565 Reported by Kaveh R. Ghazi.
11567 1993-11-20 François Pinard <pinard@iro.umontreal.ca>

11572 * acconfig.h: New, for documenting HAVE_EFGCVT.
11573 * Makefile.in: Distribute acconfig.h, .stamp-h.in and config.h.in,
11574 use them wherever appropriate. Also use -I. for compilations.

11578 * m4.h: Test for HAVE_MEMORY_H instead of NEED_MEMORY_H.
11579 * configure.in: Use AC_HAVE_HEADERS(memory.h), delete AC_MEMORY_H.
11581 1993-11-17 François Pinard <pinard@iro.umontreal.ca>
11583 * builtin.c (m4_eval): Cast strlen to (int) before comparing.
11585 * input.c (input_init): Initialize quote and comment strings
11586 explicitely instead of calling set_quotes and set_comment: by
11587 doing so, we ensure we do not free uninitialized variables.
11589 * checks/check-them: Reverse arguments to both diff, so the
11590 expected is on the left and the obtained on the right.
11592 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
11593 macros. Delete declarations for m4error, warning, fatal and
11594 internal_error, add declaration for error_message_prefix.
11595 * m4.c: Delete m4error, warning, fatal and internal_error
11596 routines, add error_message_prefix routine.
11597 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
11598 warning with WARNING*, fatal with FATAL* and internal_error with
11599 INTERNAL_ERROR*.
11600 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
11601 this is not needed anymore.
11603 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
11604 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
11605 and debug_message, add declaration for debug_message_prefix.
11606 * debug.c: Remove static specifier for FILE *debug declaration.
11607 Delete debug_print and debug_message routines, add
11608 debug_message_prefix routine.
11609 * builtin.c, debug.c: Replace debug_print routine calls with
11610 DEBUG_PRINT* macro calls.

11615 * debug.c: Include <stdarg.h> or <varargs.h>.
11616 (trace_format): Use stdarg instead of varargs if __STDC__.
11618 * configure.in: Remove checks for vfprintf and _doprnt. These
11619 implementations use varargs tricks which are not portable enough.
11620 * lib/vfprintf.c: Deleted.
11621 * lib/_doprnt.c: Deleted.
11622 * lib/Makefile.in: Adjusted accordingly. Remove LIBOBJS.

11639 1993-11-12 François Pinard <pinard@iro.umontreal.ca>
11641 * Makefile.in (m4.dvi): Use m4.texinfo instead of m4.texi.
11642 Reported by Joel Sherrill.
11644 * builtin.c (prefix_all_builtins): Instead of the table size, use
11645 the null entry at end for stopping the loop. It was overwritten.
11646 Reported by Andreas Schwab and Jim Meyering.

11685 Reported by Tom McConnell.
11687 * Makefile.in (Makefile): Use $(SHELL).
11688 (config.status): Use $(SHELL). Use "config.status --recheck"
11689 instead of "configure --no-create", which is obsolete.
11690 Reported by Tom McConnell.
11692 1993-11-05 François Pinard <pinard@iro.umontreal.ca>
11694 * m4.c (usage): Use "%s" instead of "m4" in format string.

11836 1993-02-06 François Pinard <pinard@iro.umontreal.ca>
11838 * Makefile.in, lib/Makefile.in, check/Makefile.in: In dist goals,
11839 ensure 777 mode for directories, so older tar's will restore file
11840 modes properly.
11842 1993-01-17 François Pinard <pinard@iro.umontreal.ca>
11844 * Makefile.in, lib/Makefile.in: Put $(CFLAGS) after $(CPPFLAGS),
11845 so the installer can override automatically configured choices.
11846 Reported by Karl Berry.
11848 1993-01-15 François Pinard <pinard@iro.umontreal.ca>
11850 * lib/vfprintf.c: Stolen from Oleo distribution and adapted. The

11852 Reported by Roland McGrath.
11854 * lib/_doprnt.c: Stolen from Oleo distribution.
11855 * configure.in: Check for _doprnt.c if vfprintf.c selected.

11857 Do not distribute regex.[ch].old anymore.
11859 1993-01-01 François Pinard <pinard@iro.umontreal.ca>
11861 * Makefile.in, lib/Makefile.in: Reinstate $(CPPFLAGS), use it.
11862 Richard wants it there.
11864 1992-12-27 François Pinard <pinard@iro.umontreal.ca>
11866 * Makefile.in: Add DEFS to MDEFINES.
11867 * lib/Makefile.in (.c.o): Remove $(CPPFLAGS).

11871 1992-12-23 François Pinard <pinard@iro.umontreal.ca>
11873 * Makefile.in (dvi, m4.dvi): New goals.
11875 * builtin.c, eval.c, format.c, input.c, m4.[ch], m4.texinfo,
11876 macro.c, output.c, path.c, symtab.c: Change Copyright from
11877 1989-1992 to the explicit enumeration 1989, 1990, 1991, 1992.
11879 * examples/divert.m4: Deleted, this bug has been corrected.
11881 * Makefile.in (texclean, mostlyclean): New goals.
11883 * Makefile.in (clean): Remove clutter from ansi2knr.
11884 Reported by Pierre Gaumond.
11886 1992-12-20 François Pinard <pinard@iro.umontreal.ca>
11888 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user
11889 might well use CFLAGS is s/he needs it.
11891 * Makefile.in: Allow installation of info files from a separate
11892 build directory.
11893 Reported by Jason Merrill.
11894 Reported by David MacKenzie.
11895 Reported by Skip Montanaro.
11896 Reported by Erez Zadok.
11897 Reported by Assar Westerlund.
11898 \f
11899 1992-12-19 François Pinard <pinard@iro.umontreal.ca>
11901 * Release 1.0.3
11902 This is still a beta release for the future GNU m4 version 1.1.
11904 * lib/alloca.c: New, from elsewhere.
11905 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
11907 * m4.h: Do not define index/rindex if already defined. If
11908 FALSE/TRUE are already defined, do not redefine them, but merely
11909 define boolean typedef to int.
11911 * Makefile.in: Use $(DEFS) while compiling ansi2knr.
11912 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
11913 because some C compilers do not like connectives with #ifdef.
11914 * m4.h: Define `volatile' only if __GNUC__, instead of once for
11915 __GNUC__ and once for __STDC__.
11916 * lib/regex.h: Leave const alone, AC_CONST will take care of it.
11918 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
11919 Makefile dependencies. Without it, make keeps destroying and
11920 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.
11922 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
11923 to diversion/DIVERSION, this was a spelling error.
11925 * m4.c: Declare version[], remove #include "version.h".
11926 * version.h: Deleted.
11927 * Makefile.in: Remove references to version.h.
11929 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
11930 production, by using a simpler and more robust algorithm. This
11931 solves the problem of synclines sometimes written in the middle of
11932 an output line. Delete sync_line() and output_lines variable.
11933 * m4.h: Remove sync_line prototype and output_lines declaration.
11934 * input.c (next_char), output.c (shipout_text): Remove references
11935 to output_lines.
11936 * input.c (push_file, pop_file): Merely put the value -1 in
11937 output_current_line instead of calling sync_line, for delaying a
11938 single `#line NUM FILE' before next output line. Do not test
11939 for sync_output, because this is unnecessary clutter.
11940 * output.c (make_divertion, insert_divertion): Idem.
11941 * input.c: Rename must_advance_line to start_of_input_line, for
11942 consistency.
11944 * debug.c (trace_header): Select a new debug line format, which
11945 better complies with GNU standards for formatting error messages.
11946 With option `-dfl', M-x next-error might be used on the output.
11947 * m4.c (vmesg): Adjust format of error output to GNU standards.
11948 * m4.texinfo: Adjust examples for `make check' to work.
11950 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
11951 case for enum debug_info constants, which were all lower case.
11953 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
11954 re_search_2.
11955 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
11956 collected patches. I tried a few times using newer regex.[ch], it
11957 mysteriously stopped aborting with this one. Insecure feeling...
11958 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
11960 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
11962 * m4.c: Change `--no-warnings' to `--silent'.
11963 Reported by David MacKenzie.
11965 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
11966 leave it off for now. See comment in m4.c for justification.
11967 Reported by David MacKenzie.
11969 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
11970 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
11972 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
11974 * Makefile.in: Ensure recursive cleaning is done before local
11975 cleaning for all clean goals.
11977 * builtin.c (ntoa): Ensure the value is always interpreted as a
11978 signed quantity, whatever the radix is.
11980 1992-11-18 Jim Meyering <meyering@idefix>
11982 * builtin.c, format.c, input.c: Split long lines.
11983 * m4.c: Use typedef macro_definition instead of struct
11984 macro_definition.
11985 * symtab.c: Use typedef symbol instead of struct symbol.
11987 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
11989 * *.[ch]: Remove all trailing whitespace, in code and comments.
11991 * configure.in: Find some awk.
11992 * Makefile.in: Add $(AWK) to MDEFINES.
11993 * checks/Makefile.in: Transmit $(AWK) to get_them.
11994 * checks/get_them: Use $AWK instead of gawk. Add a close in the
11995 awk script when switching files, because without this, mawk runs
11996 out of file descriptors.
11998 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
12000 * Makefile.in (realclean): Delete m4.info*.
12001 Reported by Jim Meyering.
12003 * Makefile.in: Adjust and link with checks/Makefile.
12004 * checks/Makefile.in: New.
12005 * configure.in: Output checks/Makefile.
12007 * checks/get_them: Have the dnl header of each test more
12008 recognizable by next-error, also use a better message.
12010 1992-11-16 Jim Meyering <meyering@idefix>
12012 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
12013 And use that only if __GNUC__ since we're using it's GCC-specific
12014 semantics that tell the compiler the associated function doesn't
12015 return.
12017 * builtin.c (substitute): Don't use character as an array index.
12018 (dumpdef_cmp): Make formal arguments `const void *' to avoid
12019 warnings with gcc -W -Wall on systems with qsort prototype.
12020 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
12021 from gcc -W -Wall.
12023 * eval.c (most functions): Add parentheses to assignments used
12024 as truth values go avoid warnings from gcc -Wall.
12026 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
12027 any functions that don't need external scope.
12029 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
12030 (many functions and arrays): Declare `const'.
12032 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
12034 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
12035 removing the declaration from m4.h. Also rename false to FALSE
12036 and true to TRUE.
12038 * lib/Makefile.in (Makefile): New goal.
12040 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
12041 so heavily loaded. It gets more easily overridable, calling make.
12042 Reported by Jim Meyering.
12044 * Makefile.in (dist): Get .fname from the current directory name,
12045 instead of from version.h. I need updating many files manually,
12046 when the version changes, version.h is just one of them.
12048 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
12050 * m4.h: Remove the tag `boolean' on the enum introducing typedef
12051 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
12052 Reported by Tom McConnell.
12054 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
12056 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
12057 39.cleardiv, which were describing missing or spurious newlines.
12058 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
12059 do not depend on machine word size, `/bin/false' implementation,
12060 or `wc' output format. `make check' is more dependable, now.
12062 * checks/check_them: Summarize the failed tests by listing their
12063 name, at end. If none, issue `All checks successful'. Output
12064 `Checking' instead of `Input file:'.
12066 * checks/get_them, checks/check_them: Reindented.
12068 * Makefile.in (dist): chmod a+r before making the tar file.
12070 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
12072 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
12074 * input.c (next_token): Reinitialize token_buttom just after using
12075 it as a watermark with obstack_free. Or else, a future token, big
12076 enough for triggering reallocation of the obstack chunk, could
12077 void the initialized value of token_buttom, later causing panic in
12078 obstack_free. Rename token_buttom to token_bottom everywhere.
12080 * m4.h: Before declaring errno, first include <errno.h> and
12081 ensure that it does not define errno.
12082 Reported by Richard Stallman.
12084 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
12086 * builtin.c: Define and use DECLARE macro for builtins.
12088 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
12089 argument, this is a common idiom for introducing long comments.
12091 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
12092 arguments. The last argument was silently ignored.
12094 * m4.c (cmd_error): Add a missing semicolon before va_end().
12096 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
12098 * Makefile.in: Now handle protoized sources. Define and use U.
12099 Compile and use ansi2knr with old compilers. Update DISTFILES.
12100 Add `aclocal.m4' to `configure' dependencies.
12101 * ansi2knr.c: New, from Ghostscript distribution.
12102 * configure.in: Define U through FP_PROTOTYPES for old compilers.
12103 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
12104 * aclocal.m4: New, provide FP_PROTOTYPES.
12105 * m4.h: Conditionnaly protoized through Args, save for varags.
12106 * builtin.c: Protoized. Then:
12107 Include <sys/types.h> if size_t is not defined, before "regex.h".
12108 (m4_ifelse): Fetch built-in name properly for diagnostic.
12109 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
12110 (m4_regexp): Add const to `msg' declaration.
12111 (m4_patsubst): Add const to `msg' declaration.
12112 * debug.c: Protoized, save for varargs.
12113 * eval.c: Protoized.
12114 * format.c: Protoized.
12115 * input.c: Protoized.
12116 * m4.c: Protoized, save for varargs. Then:
12117 (xfree): Accept void * instead of char *.
12118 (xmalloc): Return void * instead of char *.
12119 (xrealloc): Accept and return void * instead of char *.
12120 * macro.c: Protoized.
12121 * output.c: Protoized.
12122 * path.c: Protoized. Then cast some (char *) over xmalloc's.
12123 * symtab.c: Protoized.
12125 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
12127 * m4.texinfo: Remove directory from diagnostics in 30.include,
12128 51.eval, 56.errprint and 57.m4exit tests.
12130 * m4.h: Remove declarations for int or void system functions, they
12131 cause more conflicting trouble than they make good.
12133 * configure.in: Avoid configuration header file. Add some tests.
12134 * m4.h: Remove #include "config.h".
12135 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
12136 Then, rewritten for better compliance with GNU standards.
12138 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
12140 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
12141 because of a misplaced #endif.
12143 * Many *.[hc] files: Correct intra-line spacing here and there,
12144 according to GNU indent 1.6 advice.

12150 Reported by Jason Merrill.
12152 * symtab.c (hash): Change (char) NULL to '\0'.
12153 Reported by Jason Merrill.
12155 * Delete .vers, etc/newdist.sh, etc/newvers.sh and
12156 etc/nextvers.sh. Release numbers will be edited `by hand'.
12157 * version.h: De-automatize, force value in.
12159 * m4.c: Changes in order to use a newer getopt.h.
12160 Reported by David MacKenzie.
12162 * checks/: New name for examples/.
12163 * checks/get_them: New location for etc/get_examples.
12164 * checks/check_them: New location for etc/check_examples.
12165 * Makefile.in, checks/get_them, checks/check_them: Adjust.
12166 * lib/vfprintf.c: New location for etc/vfprintf.c.
12167 * Delete empty etc/.
12168 * examples/: New name for test/.
12170 1992-03-10 François Pinard <pinard@iro.umontreal.ca>
12172 * Makefile.in (check): Add m4 as dependency.
12174 * m4.c: Accept --no-warnings instead of --no_warnings, and
12175 --no-gnu-extensions instead of --no_gnu_extensions. Make the
12176 usage message more informative.
12177 Reported by David MacKenzie.

12188 code disposition by hand.
12190 1992-03-08 François Pinard <pinard@iro.umontreal.ca>
12192 * m4.h: Delete definitions for abort() and exit().
12193 Reported by Richard Stallman.
12195 * config/hmake-unicos, config/s-unicos.h: New files.
12196 Reported by Hal Peterson.
12198 * eval.c (exp_term): Have N^0 return 1.
12199 Reported by Michael Fetterman.

12208 * Release 1.0. Many thanks to those, who provided me with bug
12209 reports and feedback.
12211 * Uses GNU configure, taken from the gdb distribution.
12213 * Uses GNU getopt(), with long option names.
12215 * The -Q/+quiet option is added, which suppresses warnings about
12216 missing or superflous arguments to built-in macros.
12218 * Added default options via the M4OPTS environment variable.
12220 * The built-in format can now be configured to use sprintf as
12221 the formatting engine, for systems without [efg]cvt(3).
12223 * GNU library code is moved to the ./lib subdirectory; other
12224 utility files are now in ./etc.
12226 * Several minor bugs have been fixed.
12227 \f
12228 1991-07-26 René Seindal <seindal@diku.dk>
12230 * Fixed various bugs. Release 0.99, manual 0.09. Many thanks to
12231 François Pinard and Roland H. Pesch for providing me with reports.
12233 * The builtins incr and decr are now implemented without use of
12234 eval.
12236 * The builtin indir is added, to allow for indirect macro calls
12237 (allows use of "illegal" macro names).
12239 * The debugging and tracing facilities has been enhanced
12240 considerably. See the manual for details.
12242 * The -tMACRO option is added, marks MACRO for tracing as soon
12243 as it is defined.
12245 * Builtins are traced after renaming iff they were before.
12247 * Named files can now be undiverted.
12249 * The -Nnum option can be used to increase the number of
12250 divertions available.
12252 * Calling changecom without arguments now disables all comment
12253 handling.
12255 * The function m4_patsubst() is now consistently declared
12256 static.
12258 * A bug in dnl is fixed.
12260 * A bug in the multi-character quoting code is fixed.

12277 expressions.
12279 * Implemented builtin "patsubst" for substitution with regular
12280 expressions.
