1448 2006-06-19 Eric Blake <ebb9@byu.net>
1452 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1454 * Makefile.am (src_m4_DEPENDENCIES): Make dependency explicit.
1455 (clean-local): Split into and depend upon...
1456 (clean-local-tests, clean-local-src): ...these two. The latter
1457 removes the libtool object directory below `src', to work around
1458 a buglet in Automake, failing to list it.
1459 (EXTRA_DIST): Distribute modules/perl.c.
1461 2006-06-19 Eric Blake <ebb9@byu.net>
1463 * Makefile.am ($(srcdir)/doc/m4.1): No need to list $(srcdir) in
1464 right side of dependency; VPATH does that.
1465 (stamp-vcl): Update to use libtool's algorithm.
1466 (EXTRA_DIST): Distribute stamp-vcl.
1467 Reported by Ralf Wildenhues.
1468 (TESTSUITE): Revert earlier change that used absolute path, as
1469 that broke 'make dist' in VPATH. Stick with $(srcdir) instead.
1470 (EXTRA_DIST): Revert earlier change of $(TESTSUITE).
1471 (TESTS_ENVIRONMENT) [USE_GMP]: Revert earlier addition, since
1472 atlocal takes care of it instead.
1473 (check-local, installcheck-local, clean-local): Inline absolute
1474 path to testsuite here, rather than relative path to testsuite
1477 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1479 * m4/m4private.h (DELETE): Cast away const here...
1480 * src/stackovf.c (stackovf_exit): ...to avoid cast-as-lvalue here.
1481 * src/freeze.c (reload_frozen_state): Avoid uninitialized
1484 2006-06-19 Eric Blake <ebb9@byu.net>
1486 * Makefile.am (doc/m4.1): Build in $(srcdir), to match where
1487 .info pages are built.
1488 Reported by Ralf Wildenhues.
1489 (EXTRA_DIST): Inline definition of testsuite, so that make dist
1492 2006-06-16 Eric Blake <ebb9@byu.net>
1494 Follow recommendations from autoconf manual for autotest.
1495 * Makefile.am (TESTSUITE): Factor the $(srcdir) out of uses, and
1496 turn it into an absolute path until autotest provides an option
1497 that allows us to avoid changing directories. Properly quote
1499 (TESTS_ENVIRONMENT) [USE_GMP]: Inform testsuite about GMP.
1500 (check-recursive): Delete unused target.
1501 ($(TESTSUITE)): Atomically update testsuite.
1502 (CD_TESTDIR): Simplify.
1503 (m4__cd): Delete unused macro.
1504 (check-local): Let TESTSUITEFLAGS influence the run.
1505 (installcheck-local): Let TESTSUITEFLAGS override
1506 AUTOTEST_PATH. Add dependencies.

1508 (DISTCLEANFILES, MAINTAINERCLEANFILES): Add directory location.
1509 * README: Document how to use the testsuite.
1511 2006-06-15 Eric Blake <ebb9@byu.net>
1513 * configure.ac (M4_DEFAULT_PRELOAD): Fix typo in last commit.
1515 * ltdl/m4/m4-error.m4 (M4_ERROR): Use M4_ instead of m4_ to avoid
1516 clashes with m4sugar.

1524 * configure.ac: Likewise.
1525 (M4_DEFAULT_PRELOAD): Use as a macro, not shell variable.
1526 * Makefile.am (src_m4_CPPFLAGS): Use STACKOVF as a makefile
1528 * ltdl/m4/m4-gnulib.m4: Delete, no longer needed.
1530 Reduce compiler warnings. Inside GMP, mpq_t is an array type, so
1531 const mpq_t is not assignable from plain mpq_t. Avoid
1532 type-punning warnings caused trying to mix these types.
1533 * modules/mpeval.c (numb_ior, numb_eor, numb_and, numb_lshift),
1534 (numb_rshift, numb_divide, numb_modulo): Remove const qualifier.
1535 * modules/evalparse.c (or_term, xor_term, and_term, shift_term),
1536 (mult_term, exp_term): Remove type-punning casts.
1537 (numb_pow): Remove const qualifier.
1538 * src/freeze.c (reload_frozen_state): Fix typo in messages.
1539 Fix variables that can be used uninitialized, which fixes
1540 security hole where malicious frozen file can execute arbitrary

1545 * Makefile.am (modules_mpeval_la_LIBADD): Readd $(LIBADD_GMP).
1547 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1548 Eric Blake <ebb9@byu.net>
1550 Allow `make dist' to work again.

1552 (MAINTAINERCLEANFILES): Avoid redundant mention of dist_man_MANS.
1553 (cvs-dist): Fix typo.
1554 * NEWS: Match current version number.

1558 * Makefile.am (AM_CPPFLAGS): Add $(LTDLINCL), so the right
1561 * bootstrap: Do not run libtoolize manually, this is done
1562 correctly by autoreconf. Invoke autoreconf with --no-recursive
1563 to avoid unnecessary rerunning of autotools for libltdl.
1565 2006-06-13 Eric Blake <ebb9@byu.net>
1569 2006-06-12 Eric Blake <ebb9@byu.net>
1571 * m4/output.c [HAVE_MKTEMP]: Gnulib provides mkstemp, so don't
1573 * src/m4.h: Don't declare mktemp.
1574 * m4/input.c (m4__next_token): Avoid bzero.
1575 * configure.ac (AC_CHECK_FUNCS): Remove obsolete checks.
1576 * Makefile.am (doc/m4.1): Depend on installed help2man, rather
1577 than distributing outdated helptoman.pl.
1578 * doc/helptoman.pl: Delete.
1580 2006-06-10 Eric Blake <ebb9@byu.net>
1582 * README (Patches): Document the current dependence on CVS
1583 builds of autotools.
1584 * ltdl/m4/gnulib-cache.m4: Update, and use --macro-prefix=M4.
1585 * configure.ac: Use consistent quoting throughout.
1586 (AC_PREREQ): Bump to 2.59d.
1587 (AC_INIT): Package name begins with uppercase.
1588 (AC_ARG_WITH): Use AS_HELP_STRING.
1589 (AM_INIT_AUTOMAKE): Enable gnits mode.
1590 (AC_ISC_POSIX, AM_PROG_CC_STDC, AC_PROG_INSTALL, AC_PROG_MAKE_SET),
1591 (AC_PROG_AWK, AM_C_PROTOTYPES, AC_C_CONST, AC_HEADER_STDC),
1592 (AC_CHECK_HEADERS, AC_FUNC_ALLOCA, AC_FUNC_VPRINTF): Remove checks
1593 done by gnulib or automake, or which autoconf has declared

1599 * modules/m4.c (Includes): Likewise.
1600 * src/m4.h (Includes): Likewise.
1602 * README-alpha: Update web address.
1603 * README: Likewise. Change encoding to ASCII. Remove old advice
1604 about cygwin. Document bootstrapping dependency.
1605 * AUTHORS: Update from branch-1_4.
1606 * THANKS: Likewise. Change encoding to UTF-8.
1607 * BACKLOG: Delete. This file is too old and unmaintained to be
1609 * ChangeLog: Change encoding to UTF-8.
1611 Avoid compiler warnings.
1612 * m4/macro.c (trace_format): Don't mark this as a printf format,
1613 since we don't accept the same set of modifiers as printf. It
1614 would be nice if gcc let us specify a custom format archetype.
1615 * src/main.c (main): Cast away const.
1617 2006-06-10 Andreas Schwab <schwab@suse.de> (tiny change)
1618 Eric Blake <ebb9@byu.net>
1620 * modules/time.c (ctime): Pass correctly typed variable to
1623 (localtime): Likewise.

1625 * m4/utility.c (m4_numeric_arg): For now, document arbitrary
1626 limit inherent in this interface.
1628 2006-05-08 Bruno Haible <bruno@clisp.org> (tiny change)
1630 * modules/m4.c (WEXITSTATUS): Provide fallback definition.
1631 (sysval): Use WEXITSTATUS.
1632 * modules/gnu.c (esyscmd): Set sysval to 0xffff, to accomodate both
1633 big-endian and little-endian wait status definitions.
1635 2006-05-06 Eric Blake <ebb9@byu.net>
1637 * po/Makevars (MSGID_BUGS_ADDRESS): Add.
1638 * po/POTFILES.in (src/getopt.c, src/version-etc.c): These files live
1641 2006-05-06 Eric Blake <ebb9@byu.net>
1643 * configure.ac (LT_CONFIG_LTDL_DIR): Inform libtool which
1644 subdirectory to use.
1645 (support for -pipe): Move after LT_INIT, since it relies on

1667 2005-12-05 Gary V. Vaughan <gary@gnu.org>
1669 * bootstrap (func_update_po): Synch with CVS GNU tar. wget 1.9.x
1670 and 1.10.x support --cache=off, so $WGETFLAGS are not necessary.
1671 Reported by Eric Blake <ebb9@byu.net>
1673 2005-12-04 Gary V. Vaughan <gary@gnu.org>
1675 * bootstrap (func_update_po): Test and set $WGETFLAGS to disable
1676 http caching as -C is no longer supported by wget 1.10.x.
1677 Reported by Eric Blake <ebb9@byu.net>
1679 2005-10-20 Gary V. Vaughan <gary@gnu.org>
1681 * m4/module.c (caller_id): To match libtool-2.0 interface, changed
1683 (iface_id): ...an lt_dlinterface_id type.
1684 (m4__module_find): New abstraction for lt_dlhandle_fetch. Use
1685 throughout, instead of calling obsolete lt_dlhandle_find directly.
1686 (m4__module_next): Use multiloader-safe lt_dlhandle_iterate. Use
1687 throughout, instead of calling obsolete lt_dlhandle_next.
1688 * m4/m4private.h (m4__module_find): Declare it.
1689 * m4/builtin.c (m4_builtin_find_by_name, m4_builtin_find_by_func):
1690 Use m4__module_next instead of obsolete lt_dlhandle_next.
1692 2005-10-20 Gary V. Vaughan <gary@gnu.org>
1694 * bootstrap (func_update_po): Update pofiles directly from the
1695 translation project.

1697 po/ja.po, po/nl.po, po/pl.po, po/ru.po, po/sv.po: No need to store
1698 these files under source control anymore.
1699 Suggested by Eric Blake <ebb9@byu.net>
1701 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
1703 * ltdl/m4/m4-gnulib.m4: Update FSF contact address. Somehow this
1704 file escaped the address updates on 2005-05-01.
1706 2005-07-07 Gary V. Vaughan <gary@gnu.org>
1708 * bootstrap: Allow user overriding of gnulib-tool location, and
1709 correctly determine module source directories whether gnulib-tool
1710 is given as a relative or absolute path, or is found by searching
1712 Reported by Eric Blake <ebb9@byu.net>
1714 2005-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1716 * ltdl/m4/debug.m4 (m4_CHECK_DEBUGGING): Make sure that both $rm

1731 level symbol rename.
1732 * m4/m4module.h (m4_symbol_rename): Declare it as part of the API.
1733 * modules/gnu.c (regsub): Factored out of m4_epatsubst_do...
1734 (m4_patsubst_do, m4_renamesyms_do): ...wrappers that use
1736 (erenamesyms, renamesyms): ...builtins that use these to implement
1737 macro renaming by regular expression.
1738 * doc/m4.texinfo (Erenamesyms and Renamesyms): Document them.
1739 * tests/generate.awk: Allow some forbidden `m4_' prefixed symbols
1740 to stop the new generated tests from choking.
1742 2005-05-07 Gary V. Vaughan <gary@gnu.org>
1744 Since most of the build is handled from a single Makefile.am now,
1745 we can teach make about the dependencies between the m4 binary and
1746 the preopened modules it is built against:
1748 * configure.ac (PREOPEN_DEPENDENCIES): Substitute for a list of
1750 * Makefile.am (src_m4_DEPENDENCIES): Rebuild the m4 program if any
1751 of the preopened modules have changed.
1753 2005-05-07 Gary V. Vaughan <gary@gnu.org>
1755 * configure.ac (gl_MODULES): Add mkstemp for machines that don't
1756 have a native implementation.
1758 2005-05-06 Gary V. Vaughan <gary@gnu.org>
1760 * src/m4.h (EXIT_SUCCESS, EXIT_FAILURE): Removed. These are
1761 handled already by gnu/exit.h.
1763 * configure.ac (gl_MODULES): Add assert to support a
1764 --disable-assert configure time option for NDEBUG setting.
1766 * Makefile.am (src_m4_SOURCES): Add version-etc-fsf.c.
1767 * bootstrap (src_modules): Add version-etc-fsf.
1768 * src/main.c (version_etc_copyright): Removed.
1770 * ltdl/m4/m4-getopt.m4 (m4_GETOPT): Synch with gnulib/getopt.m4.
1772 2005-05-04 Gary V. Vaughan <gary@gnu.org>
1774 * src/m4.h (__CYGWIN__, WIN32): Canonicalise Windows and Cygwin
1776 * src/freeze.c (produce_frozen_state): Use \n line-endings even
1777 on Windows, so that the frozen file reader will work.

1780 2005-05-04 Vincent Lonngren <Vincent.lonngren.759@student.lu.se>
1782 Forward port of a patch that allowed m4-1.4.2 to compile on
1785 * configure.ac (AC_CHECK_HEADERS): Add signal.h,
1787 * src/m4.h: And include them as appropriate.
1788 * src/main.c, src/stackovf.h: Don't include signal.h literally;
1789 m4.h will include the correct file.
1791 2005-05-04 Gary V. Vaughan <gary@gnu.org>
1793 * m4/m4private.h: Make errno visible for the sources patched
1796 2005-05-04 Paul Eggert <eggert@twinsun.com>
1798 * src/main.c (print_program_name_CB): Preserve errno, since
1799 M4ERROR relies on this.
1800 * modules/gnu.c (m4_esyscmd): Clear errno before calling popen.
1801 * modules/m4.c (m4_maketemp): Clear errno before calling mkstemp.
1802 * m4/path.c (m4_path_search): Don't let "free" trash errno when
1805 * m4/output.c (m4_insert_file): Don't assume errno has a valid
1806 value simply because fread returns zero. This fixes a
1807 portability bug reported by Marion Hakanson in
1808 <http://lists.gnu.org/archive/html/bug-m4/2004-07/msg00029.html>.
1810 2005-05-04 Santiago Vila <sanvila@debian.org>

1817 * m4/output.c (m4_insert_file): Do not mix buffered and
1818 unbuffered I/O, as this breaks on the Hurd.
1820 2005-05-04 Gary V. Vaughan <gary@gnu.org>
1822 Gnulib has changed again. Reimport. Adjust. Rinse. Repeat.
1823 Automake and Libtool now agree on subdir-objects and LTLIBOBJS,
1824 and libtoolize does a better job of ltdl importing now too, so
1825 take advantage of that while updating the tree:
1827 * acm4, config: Moved from here...
1828 * ltdl/m4, ltdl/config: ...to here.
1829 * doc/Makefile.am, m4/Makefile.am, modules/Makefile.am,
1830 src/Makefile.am, tests/Makefile.am: Removed...
1831 * Makefile.am: ...and migrated to here, with adjustments to
1832 compensate for relative path differences.
1833 * commit: Adjust relative paths.
1834 * configure.ac: Adjust relative paths.
1835 (AC_PREREQ): 2.59 isn't strictly new enough, we also need a
1837 (LT_PREREQ): 2.0 isn't released yet, but will work when it is! In
1838 the meanwhile, CVS HEAD libtool is needed.
1839 (AM_INIT_AUTOMAKE): Added subdir-objects declaration. 1.9.5 isn't
1840 stricly new enough, we also need a patch.
1841 (AM_PROG_CC_C_O): Required for subdir-objects in Automake.
1842 (AC_WITH_LTDL): Replaced with LT_WITH_LTDL.
1843 (gl_MODULES): Don't list getopt and version-etc, as they don't
1845 * bootstrap: After running gnulib-tool to import the listed
1846 modules, fetch getopt and version-etc into src manually.
1847 (ltdldir): Change to ltdl.
1848 * src/main.c: Adjust for changes in version-etc API.
1849 * ltdl/m4/m4-getopt.m4: New macro to mirror gnulib's getopt.m4,
1850 but works when the getopt module isn't to be included in the lib.
1851 * README: Add note about patching autoconf and automake to

1857 * doc/m4.texinfo (Maketemp): Change maketemp to refer to a new,
1858 empty file rather than to a nonexistent file. This closes a
1859 common security hole.
1860 * modules/m4.c (m4_maketemp): Implement the above, by using
1861 mkstemp rather than mktemp.
1863 2005-05-01 Gary V. Vaughan <gary@gnu.org>

1910 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
1911 (m4_is_syntax_macro_escaped): Similarly protect function
1912 definitions from macro expansion under -DNDEBUG by #undefing the
1913 matching macro names before each definition. Also, move all the
1914 function definitions to the end of the file so that any
1915 invocations in the rest of the file pick up the fast macro
1917 * m4/m4private.h (m4_set_symbol_table, m4_set_syntax_table)

1929 2004-09-23 Gary V. Vaughan <gary@gnu.org>
1931 * src/main.c: Include gnulib files from the correct directory.
1933 * gnulib/*: Don't store any of the gnulib files in arch, as they
1934 generate spurious changes.
1935 * Makefile.am (ACLOCAL_AMFLAGS): Remove gnulib/acm4 since the
1936 gnulib macros now share our macro directory.
1937 (SUBDIRS): Descend into `gnu' rather than `gnulib'.
1938 * bootstrap: Call gnulib-tool to import from the gnulib tree.
1939 (gl_AC_HEADER_INT_TYPES_H, gl_AC_HEADER_STDINT_H,
1940 gl_AC_TYPE_UINTMAX_T): Patch gnulib.m4 to define these in terms of
1941 the gettext macros from autopoint that overwrite the gnulib-tool
1942 imported versions. Import sources and Makefile.am into the `gnu'
1943 directory. Changed all callers.
1944 * configure.ac (gl_EARLY, gl_SOURCE_BASE, gl_M4_BASE, gl_MODULES,
1945 gl_INIT): Call these gnulib-tool macros instead of the hardcoded
1946 for imported modules.
1947 * acm4/m4-error.m4, acm4/m4-gettext.m4, acm4/m4-obstack.m4,
1948 acm4/m4-regex.m4: Use AC_BEFORE to enforce ordering rather than
1949 hardcoding the gnulib macros they wrap.
1951 2004-07-15 Gary V. Vaughan <gary@gnu.org>
1953 Latest CVS libtool can preload modules in libraries, including
1954 its own module loaders! Tweak m4 so that it doesn't try to treat
1955 libltdl's module loaders as m4 modules when freezing and on exit:
1957 * gnulib/acm4/*.m4: Don't store these files in arch since they
1958 generate spurious changes.
1959 * bootstrap: Simplify initial libtoolize call, since CVS
1960 libtoolize is smarter these days.
1961 * doc/Makefile.am (%.1): Make the helptoman call work with a VPATH
1963 * m4/module.h (m4__module_exit): Missing declaration.
1964 * m4/m4private.h (m4__module_next): New function declaration.
1965 * m4/module.c (m4__module_next): lt_dlhandle_{firs,nex}t
1966 encapsulation. Changed all callers.
1967 (m4__module_interface): New function to verify m4 loadable module
1969 (m4__module_init): Register the interface validator.
1970 (m4__module_exit): Only close my own modules.
1971 * modules/m4.c (unistd.h): Provide missing declaration.
1972 (m4_set_sysval, m4_sysval_flush, m4_dump_symbols)
1973 (m4_expand_ranges): More missing declarations.
1974 * modules/modtest.c (export_test): Ditto.
1975 * src/Makefile.am (AM_CPPFLAGS): Add libltdl directory.
1976 * src/main.c (main): Bump copyright year.
1977 * tests/modules.at: Fix sed syntax error.
1980 2004-06-17 Gary V. Vaughan <gary@gnu.org>
1982 Tweaking to enable compilation with latest CVS libtool and
1983 libltdl. We can't just dump the library files directly into the
1984 m4 directory anymore now that libltdl is built from pieces itself:
1986 * bootstrap: Rewritten to use latest libtoolize sanely, and to
1987 set up libltdl subdirectory.
1988 * configure.ac (AC_CONFIG_AUX_DIR): Point to our own, not the
1989 gnulib subdirectory's config.
1990 (TIMESTAMP): Use $ac_aux_dir for VPATH builds.
1991 (m4_pattern_forbid): Remove the cruft to deal with renamed jm_
1993 (AC_LIB_LTDL): Latest libltdl is a sub-project with its own
1994 configure.ac, so use AC_WITH_LTDL instead.
1995 * Makefile.am (SUBDIRS): Add libltdl.
1996 * acm4/m4-regex.m4 (jm_INCLUDED_REGEX): Updated. gnulib now uses
1998 * m4/Makefile.am (AM_CPPFLAGS): Add INCLTDL.
1999 (libm4_la_SOURCES): Remove ltdl.c and ltdl.h.
2000 (libm4_la_LIBADD): Add LIBLTDL.
2001 * m4/ltdl.c, m4/ltdl.h: Removed.
2002 * m4/m4module.h: Include canonical ltdl.h.
2005 2004-06-14 Gary V. Vaughan <gary@gnu.org>
2007 * gnulib/import: Now updates makefile fragments, and configure.ac.
2008 * gnulib/m4/gnulib.am: New file. Generated makefile fragments.
2009 * gnulib/m4/Makefile.am: include it.
2010 * gnulib/acm4/intmax.m4, gnulib/acm4/longdouble.m4,
2011 gnulib/acm4/longlong.m4, gnulib/acm4/printf-posix.m4,
2012 gnulib/acm4/signed.m4, gnulib/acm4/size_max.m4,
2013 gnulib/acm4/wchar_t.m4, gnulib/acm4/wint_t.m4,
2014 gnulib/acm4/xsize.m4: New macro files from latest gnulib import.
2015 * gnulib/acm4/alloca.m4, gnulib/acm4/inttypes_h.m4,
2016 gnulib/acm4/lib-ld.m4, gnulib/acm4/lib-prefix.m4,
2017 gnulib/acm4/error.m4, gnulib/acm4/po.m4, gnulib/acm4/regex.m4,
2018 gnulib/acm4/stdbool.m4, gnulib/acm4/stdint_h.m4,
2019 gnulib/acm4/uintmax_t.m4, gnulib/acm4/ulonglong.m4,
2020 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
2021 gnulib/acm4/free.m4, gnulib/acm4/gettext.m4,
2022 gnulib/acm4/glibc21.m4: Updated macro files from latest gnulib
2024 * gnulib/m4/getopt_int.h: New source file from latest gnulib
2026 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/getopt1.c,
2027 gnulib/m4/obstack.c, gnulib/m4/obstack.h, gnulib/m4/regex.c,
2028 gnulib/m4/unlocked-io.h, gnulib/m4/version-etc.c,
2029 gnulib/m4/xmalloc.c, gnulib/m4/getopt.c, gnulib/m4/getopt.h:
2030 Updated source files from latest gnulib.
2032 2004-02-29 Gary V. Vaughan <gary@gnu.org>
2034 * config/mailnotify: New file for mailing commit notifications,
2035 imported from cvs-utils.
2036 * commit: Updated from cvs-utils and tweaked for m4.
2038 2003-12-01 Gary V. Vaughan <gary@gnu.org>
2040 * config/mkstamp: Updated from CVS libtool.
2041 * configure.ac: Generate a gnu coding standards compliant version
2042 number, and use it for the banner.
2043 * Makefile.am (stamp-vcl): New rules to force m4 to be regenerated
2044 mhen the TIMESTAMP changes in ChangeLog, but the file modification
2045 time doesn't (e.g. in cvs commit). Otherwise dist tarballs will
2046 contain the previous version number.
2047 * src/main.c: Make --version output conform to the GNU standard.
2049 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7g...
2050 * modules/Makefile.am (gnu_la_SOURCES, load_la_SOURCES,
2051 m4_la_SOURCES, traditional_la_SOURCES, modtest_la_SOURCES,
2052 shadow_la_SOURCES, import_la_SOURCES, stdlib_la_SOURCES,
2053 time_la_SOURCES): ...so that these are defaulted correctly, and
2054 can be removed from this file.
2055 (AM_LDFLAGS): Add -module...
2056 (gnu_la_LDFLAGS, load_la_LDFLAGS, m4_la_LDFLAGS,
2057 traditional_la_LDFLAGS, modtest_la_LDFLAGS, shadow_la_LDFLAGS,
2058 import_la_LDFLAGS, stdlib_la_LDFLAGS, time_la_LDFLAGS): ...so that
2059 the individual settings can be removed.
2060 * m4/Makefile.am (libm4_la_LIBADD): Add $(LTLIBINTL) here once...
2061 * module/Makefile.am (gnu_la_LIBADD, load_la_LIBADD,
2062 m4_la_LIBADD, traditional_la_LIBADD, modtest_la_LIBADD,
2063 shadow_la_LIBADD, import_la_LIBADD, stdlib_la_LIBADD,
2064 time_la_LIBADD): ...so that these are picked up as a deplib of
2065 libm4 and don't need to be set explicitly.
2067 2003-11-18 Gary V. Vaughan <gary@gnu.org>
2069 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Remove perl.la
2070 from the standard build. It is too fragile.
2072 * gnulib/acm4/libtool.m4, m4/ltdl.c, m4/ltdl.h: Reimported from
2073 CVS libtool after merging m4 changes across to libtool.
2075 * m4/symtab.c (m4_symtab_create): Fix a careless use of sizeof.
2076 * m4/path.c (search_path_add): Ditto.
2078 2003-11-13 Gary V. Vaughan <gary@gnu.org>
2080 * configure.ac (AC_LIBTOOL_TAGS): Don't include shell code for
2081 libtool tags we don't use in configure. This reduces the size
2082 of the script from over 1Mb to under 700Kb.
2084 2003-11-13 Gary V. Vaughan <gary@gnu.org>
2086 The import script was not written properly, and the last gnulib
2087 import was incomplete. Fixed that problem, and reimport our
2088 gnulib dependencies, which picks up the address calculation
2089 overflow checks described by Paul below. Also tweak the clients
2090 of the gnulib xalloc module not to use deprecated macros:
2092 * gnulib/import: Recurse through module dependencies rather than
2093 naively descending only one level.
2094 * configure.ac: Add calls to gnulib's strnlen and extension module
2096 * gnulib/m4/Makefile.am: Add snippets from gnulib's strnlen and
2098 * gnulib/acm4/extensions.m4, gnulib/acm4/xalloc.m4,
2099 gnulib/m4/alloca.c, gnulib/m4/obstack.c, gnulib/m4/obstack.h,
2100 gnulib/m4/stdbool_.h, gnulib/m4/unlocked-io.h, gnulib/m4/xalloc.h,
2101 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Updated from CVS
2103 * gnulib/acm4/libtool.m4: Updated from CVS libtool.
2104 * m4/hash.c (m4_get_hash_iterator_next): Use `xzalloc (S)' in
2105 place of `xcalloc (1, S)'.
2106 * m4/m4.c (m4_create): Likewise.
2107 * m4/m4private.h (m4_symbol_value_create): Likewise.
2108 * m4/symtab.c (symtab_fetch): Likewise.
2109 * m4/syntax.c (m4_syntax_create): Likewise.
2110 * src/freeze.c (reload_frozen_state): Likewise.
2111 * m4/path.c (search_path_add): Eliminate use of deprecated NEW
2113 * m4/symtab.c (m4_symtab_create): Likewise.
2115 2003-11-13 Gary V. Vaughan <gary@gnu.org>
2117 * tests/module.at: Comment typo.
2119 2003-10-10 Gary V. Vaughan <gary@gnu.org>
2121 * tests/modules.at (modules: importing): Apply some lateral
2122 thinking, and use AT_CHECK to compare the output of a sed pass
2123 over stderr against the canonical strerror string.
2125 * tests/modules.at (modules: importing): Edit the generated stderr
2126 output to canonicalize strerror output, before a comparison.
2128 2003-10-10 Gary V. Vaughan <gary@gnu.org>
2130 Tru64UNIX perl is sloppy with namespace pollution. This patch is
2131 careful not to trip over the mess:
2133 * modules/perl.c: Some builds of perl install headers that contain
2134 `#define try __builtin_try'. Be sure to undefine that macro
2135 before `m4/hash.h' gets included, which uses the `try' symbol.
2136 * m4/system_.h: Similarly for `bool'. Undefine `bool', `true' and
2137 `false' before including `stdbool.h'.
2138 (DELETE): This symbol is not in m4's namespace, and is in any
2139 case only used internally...
2140 * m4/m4private.h (DELETE): ...so move it to here.
2141 Reported by Martin MOKREJS <mmokrejs@natur.cuni.cz>
2143 2003-10-08 Paul Eggert <eggert@twinsun.com>
2145 Don't use XMALLOC and XCALLOC. Once we install the
2146 corresponding patch into gnulib, this will fix some
2147 address-calculation overflow bugs on hosts where calloc (A, B)
2148 returns garbage when A*B overflows.
2150 * m4/hash.c (m4_hash_new, node_new, m4_hash_resize,
2151 maybe_grow, m4_get_hash_iterator_next): Replace XMALLOC with
2152 xmalloc, XCALLOC with xcalloc.
2153 * m4/m4.c (m4_create): Likewise.
2154 * m4/m4private.h (m4_symbol_value_create): Likewise.
2155 * m4/output.c (m4_output_init): Likewise.
2156 * m4/symtab.c (symtab_fetch, m4_set_symbol_traced): Likewise.
2157 * m4/syntax.c (remove_syntax_attribute): Likewise.
2158 * src/freeze.c (reload_frozen_state): Likewise.
2159 * src/main.c (main): Likewise.
2161 2003-10-07 Gary V. Vaughan <gary@gnu.org>
2163 * Makefile.am (ACLOCAL_AMFLAGS): Search in the new acm4 and
2164 gnulib/acm4 directories for aclocal m4 macros.
2165 * gnulib/Makefile.am (EXTRA_DIST): Removed.
2166 (MAINTAINERCLEANFILES): Add Makefile.in.
2167 * configure.ac (m4_GNULIB_MODULES): Use it to declare which gnulib
2169 * acm4/m4-gnulib.m4 (m4_GNULIB_MODULES): New macro.
2170 * gnulib/import: New file. Temporary script for updating gnulib
2171 imported files, until gnulib-tool is working.
2172 * gnulib/config/codeset.m4, gnulib/config/error.m4,
2173 gnulib/config/exitfail.m4, gnulib/config/extensions.m4,

2209 gnulib/acm4/unlocked-io.m4, gnulib/acm4/xalloc.m4,
2210 gnulib/acm4/xstrndup.m4: Reimported from CVS gnulib with
2211 gnulib/import script.
2212 * gnulib/m4/alloca.c, gnulib/m4/alloca_.h, gnulib/m4/error.c,

2216 gnulib/m4/version-etc.c, gnulib/m4/version-etc.h,
2217 gnulib/m4/xalloc.h, gnulib/m4/xmalloc.c: Updated from CVS
2218 gnulib with gnulib/import script.
2219 * configure.ac, gnulib/m4/Makefile.am: Manually insert anticipated
2220 guards ready for gnulib-tool to autoupdate on import.
2221 * config/debug.m4, config/gmp.m4, config/m4-error.m4,
2222 config/m4-gettext.m4, config/m4-obstack.m4, config/m4-regex.m4,

2225 acm4/m4-gettext.m4, acm4/m4-obstack.m4, acm4/m4-regex.m4,
2226 acm4/stackovf.m4: ...to here, to separate aclocal macros from

2237 2003-09-16 Gary V. Vaughan <gary@gnu.org>
2239 * gnulib/m4/version-etc.c, gnulib/m4/version-etc.h: Import
2240 version-etc module from CVS gnulib.
2241 * po/POTFILES.in: Add gnulib/m4/version-etc.c.
2242 * src/Makefile.am: Build it.
2243 * src/main.c: Use it.
2245 * gnulib/m4/exit.h: Import exit module from CVS gnulib.
2246 * gnulib/m4/Makefile.am (pkginclude_HEADERS): Add exit.h.
2247 * m4/system_.h: Don't define EXIT_SUCCESS and FAILURE, include
2250 2003-09-15 Charles Wilson <cygwin@cwilson.fastmail.fm>,
2251 Gary V. Vaughan <gary@gnu.org>
2253 * bootstrap: Separate options.
2254 * configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.12.1.
2255 * gnulib/m4/Makefile.am (stdbool.h): Use srcdir, gnulib_srcdir is
2257 * modules/Makefile.am (gnu_la_LIBADD, load_la_LIBADD)
2258 (m4_la_LIBADD, mpeval_la_LIBADD, traditianal_la_LIBADD)
2259 (modtest_la_LIBADD, import_la_LIBADD, perl_la_LIBADD)
2260 (shadow_la_LIBADD, stdlib_la_LIBADD, time_la_LIBADD): Add
2261 $(LTLIBINTL) for gettext support on cygwin.
2262 * src/Makefile.am (m4_LDADD): Remove $(INTLLIBS), since we now
2263 have $(LTLIBINTL) from the preloaded module la files.
2264 * README: Remove the warning about using --disable-nls on Windows
2267 2003-09-15 Gary V. Vaughan <gary@gnu.org>
2269 * gnulib/m4/regex.c: s/<regex.h>/"regex.h"/ or else the compiler
2270 picks up the system regex.h if gl_REGEX decides gnulib/m4/regex.c
2273 2003-09-12 Gary V. Vaughan <gary@gnu.org>
2275 * doc/STYLE: Document the gnulib header naming conventions, and
2277 * gnulib/m4/error_.h, gnulib/m4/gettext_.h, gnulib/m4/obstack_.h,
2278 gnulib/m4/regex_.h: Renamed to gnulib/m4/error.h,

2284 module from CVS gnulib.
2285 * configure.ac (AC_REPLACE_FUNCS): Remove strtol.
2286 (gl_FUNC_STRTOL): In favour of the module macro.
2288 2003-09-12 Gary V. Vaughan <gary@gnu.org>
2290 Replace the getopt code with CVS gnulib getopt. The source files
2291 detect whether they are in a glibc environment and preprocess away
2292 all of the code if there is a system getopt, so we can compile
2293 them into the m4 executable unconditionally:
2295 * gnulib/m4/getopt.c, gnulib/m4/getopt1.c, gnulib/m4/getopt.h,
2296 gnulib/config/getopt.m4: Import getopt module from CVS gnulib.
2297 * configure.ac (gl_GETOPT): Use this instead of homebrew inline

2301 * src/Makefile.am: Adjust.
2302 * src/main.c: Always include our shipped getopt.h.
2303 * po/POTFILES.in: Use new location of getopt.c.
2305 2003-09-12 Gary V. Vaughan <gary@gnu.org>
2307 * configure.ac (AC_CONFIG_FILES): Remove config/Makefile.
2308 * config/Makefile.am: Removed. Automake 1.8 distributes the files
2309 in this directory automatically.
2310 * Makefile.am (EXTRA_DIST): Except config/mkstamp.
2312 * configure.ac (pkglibexecdir): Don't try and set it here, PACKAGE
2314 * m4/Makefile.am (MODULE_PATH): Removed. Calculate pkglibexecdir
2316 * modules/Makefile.am (pkglibexecdir): Set it here.
2317 (pkgmodincdir): Renamed to pkgmodincludedir). Changed all clients.
2319 * gnulib/m4/regex.c, gnulib/m4/regex_.h, gnulib/config/regex.m4:
2320 Import regex module from CVS gnulib.
2321 * gnulib/config/restrict.m4: Ditto for dependee module restrict.
2322 * config/m4-regex.m4 (m4_REGEX): Wrap gnulib/config/regex.m4, but
2323 do extra substitutions for Makefile.
2324 * configure.ac: Use it.
2325 * gnulib/m4/Makefile.am: Maybe install regex.h after linking it
2326 from regex_.h if necessary.
2327 * m4/system_.h: Include the correct version of regex.h.
2328 * m4/regex.c, m4/regex.h, config/regex.m4: Removed legacy
2330 * po/POTFILES.in: Use new location of regex.c.
2332 * gnulib/m4/Makefile.am (EXTRA_DIST): Removed malloc.c and
2333 realloc.c: automake distributes these files already.
2335 2003-09-12 Gary V. Vaughan <gary@gnu.org>
2337 Replace the xstrzdup code by importing the xstrndup module from
2338 CVS gnulib, along with its dependencies: strndup and strnlen:
2340 * gnulib/m4/xstrndup.c, gnulib/m4/xstrndup.h,
2341 gnulib/config/xstrndup.m4: Import xstrndup module from CVS
2343 * gnulib/m4/strndup.c, gnulib/m4/strndup.h,
2344 gnulib/config/strndup.m4: Ditto wrt strndup.
2345 * gnulib/m4/strnlen.c, gnulib/config/strnlen.m4: Ditto wrt
2347 * gnulib/m4/Makefile.am: Add rules from newly imported modules.
2348 However, contrary to gnulib, we install xstrndup.h.
2349 * configure.ac (AC_REPLACE_FUNCS): Remove xstrzdup.
2350 * gnulib/lib/xstrzdup.c: Delete. This was never a gnulib file, it
2351 is an artifact of the old m4 portability layer.
2352 * configure.ac (gl_XSTRNDUP): This is the gnulib equivalent.
2353 * m4/system_.h: Include xstrndup.h.
2354 * m4/macro.c (process_macro): Call xstrndup, not xstrzdup.
2356 2003-09-11 Gary V. Vaughan <gary@gnu.org>
2358 Reimport the latest xalloc module from CVS gnulib, and adjust the
2359 m4 sources to take advantage of xalloc xfree. Also create a new
2360 macro DELETE with the same semantics as the old m4 XFREE macro,
2361 and carefully tweak callers:
2363 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h: Updated from CVS
2365 * m4/utility.c (xfree): Removed. This function is now supplied by
2367 * m4/m4private.h (WITH_DMALLOC): Removed XFREE redefine.
2368 * m4/path.c (search_path_add): Use NEW macro from xalloc.h.
2369 * m4/symtab.c (m4_symtab_create): Ditto.
2370 * m4/system_.h: Removed XFREE redefine.
2371 (DELETE): New macro with same functionality as the original m4
2372 XFREE macro, but based on xalloc.h now. Changed all callers.
2373 * src/main.c (main): Use XMALLOC macro.
2374 * m4/hash.c, m4/macro.c, m4/symtab.c, m4/syntax.c: Use xfree
2376 * m4/output.c (m4_output_exit): Use DELETE instead of XFREE.
2378 2003-09-10 Gary V. Vaughan <gary@gnu.org>
2380 Import the xalloc module from CVS gnulib, along with its
2381 dependencies: exitfail, malloc and realloc. We had different
2382 semantics for our XFREE and a function xfree() not supplied by
2383 gnulib, so also a bit of work to keep everything running
2386 * configure.ac (AC_REPLACE_FUNCS): Removed xmalloc and xstrdup.
2387 (gl_XALLOC): Use gnulib equivalents.
2388 * gnulib/config/exitfail.m4, gnulib/m4/exitfail.h,
2389 gnulib/m4/exitfail.c: Import exitfail module from CVS gnulib.
2390 * gnulib/config/malloc.m4, gnulib/m4/malloc.c: Ditto wrt malloc.
2391 * gnulib/config/realloc.m4, gnulib/m4/realloc.c: Ditto wrt
2393 * gnulib/config/xalloc.m4, gnulib/m4/xalloc.h,
2394 gnulib/m4/xmalloc.c, gnulib/m4/xstrdup.c: Ditto wrt xalloc.
2395 * gnulib/m4/Makefile.am: Add fragment from gnulib for newly
2397 (pkgincdir): Removed. Use pkgincludedir instead.
2398 * m4/m4private.h (XFREE): xfree already checks for NULL.
2399 * m4/system_.h: Use xalloc module, and remove macros already
2400 supplied by xalloc.h.
2401 * m4/utility.c (xfree): xalloc does not yet implement xfree, so
2402 moved the old definition from m4/xmalloc.c to here for now.
2404 2003-09-09 Gary V. Vaughan <gary@gnu.org>
2406 Import the error and progname modules from CVS gnulib. Our old
2407 error.c subsumed the functionality of both, so a little adjustment
2408 was required to accomodate the split in sources. Also added more
2409 wrapper macros to choose between a system installed error.h or our
2410 shipped gnulib error module:
2412 * m4/error.c, m4/error.h: Removed.
2413 * m4/Makefile.am: Adjust.
2414 (pkgincdir): Removed. Use pkgincludedir instead.
2415 * m4/module.h, src/main.c: Don't include `m4/error.h'.
2416 * m4/system_.h (INCLUDE_ERROR_H): Add a substitution for suitable
2418 * gnulib/m4/progname.c: Imported from CVS gnulib.
2419 * gnulib/m4/progname.h: Ditto.
2420 * src/main.c: Adjust to use progname module.
2421 * gnulib/m4/error.c: Imported from CVS gnulib.
2422 * gnulib/m4/error_.h: Ditto.
2423 * gnulib/m4/Makefile.am: Build the error module into our libgnu.la
2424 if appropriate, and link a local error.h if the system version is
2426 (libgnu_la_SOURCES) Add progname module sources.
2427 * gnulib/config/error.m4: Imported from CVS gnulib.
2428 * gnulib/config/strerror_r.m4: Ditto.
2429 * config/m4-error.c: New file. Wrap gnulib error.m4 but arrange
2430 to have ERROR_H for Makefile substitutions and tell system.h
2431 whether the system error.h should be used, or a locally installed
2433 * configure.ac (jm_PREREQ_ERROR): Replaced by a call to m4_ERROR.
2435 2003-09-09 Gary V. Vaughan <gary@gnu.org>
2437 * gnulib/m4/Makefile.am (MOSTLYCLEANFILES): Typo
2438 s/gettext_.h/gettext.h/.
2440 * bootstrap: Revert 2003-09-04 patch now that CVS autoconf and
2441 automake have been fixed.
2443 * config/m4-obstack.m4 (m4_FUNC_OBSTACK): D'oh! Now that we wrap
2444 gl_OBSTACK, which in turn calls AC_FUNC_OBSTACK, don't rerun bits
2445 of code originally snarfed from AC_FUNC_OBSTACK!!! While I'm here
2446 rename to m4_OBSTACK in light of wrapping gl_OBSTACK.
2448 2003-09-09 Gary V. Vaughan <gary@gnu.org>
2450 The gnulib obstack module requires the gnulib gettext module for
2451 systems that do not have GNU gettext installed. Because we use
2452 -Ignulib/m4 in our Makefiles it is not safe to drop gettext.h in
2453 that directory incase it clashes with the system gettext.h. This
2454 delta uses gettext_.h and extra rules in the Makefile to make a
2455 link to gettext.h when needed:
2457 * Makefile.am (auxdir): Removed. No longer used.
2458 * configure.ac (ac_aux_dir): Removed AC_SUBST. No longer used.
2459 (TIMESTAMP): List path to `mkstamp' literally, as ac_aux_dir has
2461 (AC_CONFIG_LIBOBJ_DIR): Declare this for possible future single
2462 Makefile based build.
2463 (AC_CONFIG_AUX_DIR): Now we use gnulib/config where the majority
2464 of the macros are kept.
2465 * Makefile.am (ACLOCAL_MFLAGS): Search gnulib/config first.
2466 * configure.ac (AM_INIT_AUTOMAKE): Require 1.7a.
2467 * config/Makefile (ACLOCAL_MACROS): Removed. Automake 1.7a
2468 distributes these automatically.
2469 * config/regex.m4 (jm_WITH_REGEX): Fixed underquoting to prevent
2470 warning from automake-1.7a.
2471 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Renamed to
2472 m4_CHECK_DEBUGGING for consistency with gnulib prefixes. Changed
2474 * config/m4-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto
2475 wrt. m4_FUNC_OBSTACK.
2476 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto
2477 wrt. m4_sys_STACKOVF.
2478 * config/gmp.m4 (_M4_AC_LIB_GMP, M4_AC_LIB_GMP): Ditto
2479 wrt. _m4_LIB_GMP, m4_LIB_GMP.
2480 (ac_gmp_save_LIBS, ac_cv_using_lib_gmp): Don't use autoconf's
2481 namespace. Renamed to m4_gmp_save_LIBS and m4_cv_using_lib_gmp
2483 * config/m4-gettext.m4: New file to set GETTEXT_H appropriately.
2484 * gnulib/m4/Makefile.am: Added a new block to make an appropriate
2485 gettext.h link on deficient systems.
2486 (pkginc_HEADERS): Mention $(GETTEXT_H).
2487 (EXTRA_HEADERS): Mention gettext.h.
2488 * gnulib/config/gettext_.h: New file from gnulib's gettext.h.
2489 * gnulib/config/codeset.m4, gnulib/config/gettext.m4,
2490 gnulib/config/glibc21.m4, gnulib/config/iconv.m4,
2491 gnulib/config/intdiv.m4, gnulib/config/inttypes-pri.m4,
2492 gnulib/config/inttypes.m4, gnulib/config/inttypes_h.m4,
2493 gnulib/config/isc-posix.m4, gnulib/config/lcmessage.m4,
2494 gnulib/config/lib-ld.m4, gnulib/config/lib-link.m4,
2495 gnulib/config/lib-prefix.m4, gnulib/config/nls.m4,
2496 gnulib/config/po.m4, gnulib/config/progtest.m4,
2497 gnulib/config/stdint_h.m4, gnulib/config/uintmax_t.m4,
2498 gnulib/config/ulonglong.m4: Imported from CVS gnulib.
2500 2003-09-05 Gary V. Vaughan <gary@gnu.org>
2502 We can't mirror the gnulib directory structure here, since we need
2503 to be able to eg. `#include <m4/obstack.h>' from our source files,
2504 which is much easier if the local obstack.h is created in a
2505 directory named m4. Rather than trying to symlink everything into
2506 the m4 directory, now we build a libtool convenience library from
2507 the sources we get from gnulib and link that with libm4.la:
2509 * gnulib/config/extensions.m4: Imported from CVS gnulib.
2510 * gnulib/config/unlocked-io.m4: Ditto.
2511 * gnulib/m4/unlocked-io.h: Ditto.
2512 * gnulib/m4/obstack.m4, gnulib/m4/onceonly_2_57.m4,
2513 gnulib/m4/stdbool.m4: All moved to gnulib/config directory.
2514 * gnulib/lib/obstack.c, gnulib/lib/obstack_.h,
2515 gnulib/lib/stdbool_.h: All moved to gnulib/m4 directory.
2516 * m4/strtol.c, m4/xmalloc.c, m4/xstrdup.c, m4/xstrzdup.c: Ditto.
2517 * m4/Makefile.am: Adjust.
2518 * gnulib/Makefile.am (EXTRA_DIST): Name just the additional gnulib
2519 macros we redistribute.
2520 * gnulib/m4/Makefile.am: New file. Build libgnu.la convenience
2521 library among others.
2522 (GNULIB_SRCS, GNULIB_MACROS): Removed.
2523 * Makefile.am (ACLOCAL_AMFLAGS): Adjust.
2524 * config/m4-obstack.m4: Adjust.
2525 * po/POTFILES.in: Adjust.
2526 * configure.ac: Reformatting. Call newly imported gnulib macros.
2527 * m4/builtin.c, m4/macro.c, m4/module.c, m4/utility.c: Removed
2528 bogus calls of `#include "m4.h"'.
2529 * Makefile.am: INCLUDES has been deprecated in favour of
2531 * m4/Makefile.am: Ditto.
2532 * modules/Makefile.am: Ditto.
2533 * src/Makefile.am: Ditto.
2535 2003-09-05 Gary V. Vaughan <gary@gnu.org>
2537 * config/Makefile.am: Reverting yesterdays patch for VPATH builds.
2539 2003-09-04 Gary V. Vaughan <gary@gnu.org>
2541 Migrate the obstack support into the gnulib directories for easy
2542 synchronisation with upstream files in gnulib:
2544 * config/gnu-obstack.m4: Moved from here...
2545 * config/m4-obstack.m4: ...to here.
2546 * config/Makefile.am (SPECIFIC_MACROS): Adjust.
2547 * m4/obstack.c, m4/obstack_.h: Moved from here...
2548 * gnulib/obstack.c, gnulib/obstack.h: ...to here.
2549 * po/POTFILES.in: Adjust.
2550 * gnulib/Makefile.am (GNULIB_SRCS, GNULIB_MACROS): Adjust.
2551 * m4/Makefile.am: Add a whole new section to link the obstack
2552 sources from the gnulib tree if necessary.
2553 * gnulib/m4/onceonly_2_57.m4, gnulib/m4/obstack.m4: New macros
2555 * config/m4-obstack.m4: Rewrite as a wrapper for
2556 gnulib/m4/obstack.m4.
2558 2003-09-04 Gary V. Vaughan <gary@gnu.org>
2560 GNU M4 currently builds with a number of files adapted from
2561 upstream sources. Recently the gnulib project on savannah.gnu.org
2562 has pulled together a great many of these externally maintained
2563 files. This delta is the beginnings of isolating those files
2564 maintained in gnulib to make it easy to synchronise M4 with the
2565 upstream files prior to releases.
2567 * Makefile.am (ACLOCAL_AMFLAGS): Mention gnulib/m4 macro
2569 (SUBDIRS): Added new gnulib subdirectory.
2570 * configure.ac (AC_CONFIG_FILES): Add new gnulib tree Makefiles.
2571 * config/stdbool.m4: Moved from here...
2572 * gnulib/m4/stdbool.m4: ...to here.
2573 * m4/stdbool_.h: Moved from here...
2574 * gnulib/lib/stdbool_.h: ...to here.
2575 * gnulib/Makefile.am: New file. Make sure the gnulib tree is
2577 * m4/Makefile.am: Adjust gnulib/modules/stdbool:Makefile.am based
2578 code to work with new stdbool_.h location.
2579 (gnulib_srcdir): New.
2581 2003-09-04 Gary V. Vaughan <gary@gnu.org>
2583 * config/Makefile.am (MAINTAINERCLEANFILES, ACLOCAL_MACROS)
2584 (STANDARD_TOOLS, SPECIFIC_MACROS): Needed `$(srcdir)/' for VPATH
2586 (SPECIFIC_TOOLS): New variable. Moved mkstamp to here.
2587 (EXTRA_DIST): Use it.
2589 * bootstrap: CVS autoreconf leaves file droppings. Remove
2590 aclocal.m4t incase autoreconf doesn't.
2592 2003-08-29 Gary V. Vaughan <gary@gnu.org>
2594 * m4/gnu-obstack.h: Updated from CVS gnulib. For consistency with
2595 the other gnulib imports, renamed to m4/obstack_.h.
2596 * m4/obstack.c: Updated from CVS gnulib.
2597 * m4/Makefile.am (EXTRA_HEADERS): Adjust.
2598 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Merge in additional
2599 header tests from gnulib obstack module. AC_CONFIG_LINKS knows
2600 about vpath already, and $top_srcdir upsets CVS Automake, so the
2601 $top_srcdir reference was removed.
2603 * m4/system-h.in: For consistency with the gnulib imports, renamed
2605 * m4/Makefile (EXTRA_HEADERS): Adjust.
2606 * configure.ac (AC_CONFIG_FILES): Adjust.
2608 * m4/stdbool_.h: New file from gnulib for systems without their
2610 * m4/Makefile.am: Add snippets from gnulib for C99 bool support.
2611 * config/stdbool.m4: New file. Macros from gnulib for same.
2612 * configure.ac: Use it.
2614 2003-08-27 Gary V. Vaughan <gary@gnu.org>
2616 * config/debug.m4: `perl -pi.bak -e 's/(Copyright) (\d)/$1 (C) $2/g'`
2617 * config/gmp.m4: Ditto.
2618 * config/gnu-obstack.m4: Ditto.

2663 * src/main.c: Ditto.
2664 * src/stackovf.c: Ditto.
2666 * config/gmp.m4 (M4_AC_LIB_GMP): Use AC_INCLUDES_DEFAULT:
2667 ac_default_headers is an autoconf internal variable.
2668 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
2669 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
2671 * configure.ac (AC_CONFIG_FILES): Add tests/atlocal.
2672 * tests/Makefile.am (TESTS_ENVIRONMENT): Revert the 2003-08-14
2675 2003-08-15 Gary V. Vaughan <gary@gnu.org>
2677 * configure.ac (AC_HEADER_STDBOOL, INCLUDE_STDBOOL_H): Check for
2679 * system-h.in (m4_boolean): Removed in favour of using C99 bool if
2680 possible or faking one with a typedef. Changed all callers.
2682 2003-08-15 Gary V. Vaughan <gary@gnu.org>
2684 Still cleaning up the users' module API, by taking out the stuff
2685 that isn't used by any existing modules, and moving specialised
2686 functions out of libm4 and into the module they are used by.
2688 * m4/m4module.h (m4_skip_space): No need to export this. Moved...
2689 * m4/utility.c (m4_skip_space): ...to here the home of its only
2690 use, made static and renamed to `skip_space'. Changed all
2692 * m4/m4module.h (m4_expand_ranges): Removed prototype.
2693 * m4/utility.c (m4_expand_ranges): Moved definition from here...
2694 * modules/m4.c (m4_expand_ranges): ...to here, and exported using
2696 * modules/m4.h (m4_expand_ranges_func): For lt_dlsym import
2698 * modules/gnu.c (builtin_syntax): Import and use in this
2699 builtin implementation.
2700 * m4/m4module.h (M4_DEBUG_PRINT1, M4_DEBUG_PRINT2, M4_DEBUG_PRINT3):
2702 * m4/macro.c (trace_flush): Except here where the macro is now
2704 * m4/m4module.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
2705 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): Only used internally, so
2707 * m4/m4private.h (M4_DEBUG_MESSAGE, M4_DEBUG_MESSAGE1)
2708 (M4_DEBUG_MESSAGE2, M4_DEBUG_MESSAGE3): ...to here.
2710 2003-08-14 Gary V. Vaughan <gary@gnu.org>
2712 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use the interrim new
2713 compiler based AC_CHECK_HEADER that was introduced in
2715 * config/stackovf.m4 (M4_AC_SYS_STACKOVF): Ditto.
2716 * config/gmp.m4 (AC_LIB_GMP): Ditto. And renamed to M4_AC_LIB_GMP.
2717 * configure.ac: Use renamed M4_AC_LIB_GMP.
2719 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Don't AC_REQUIRE a
2720 macro that requires arguments! This stops the shell's bad
2721 substitution error at configure time.
2723 * tests/Makefile.am (TESTS_ENVIRONMENT): Now we can pass make
2724 variables to the testsuite shell. Set the value of USE_GMP so
2725 that the gmp test will run!
2726 (check-local, clean-local): Use the TESTS_ENVIRONMENT variable.
2728 2003-08-11 Gary V. Vaughan <gary@gnu.org>
2730 Libltdl already has an excellent mechanism for accessing C symbols
2731 in modules. Lets use that! Remove all the exporting cruft and
2732 just use lt_dlsym in conjunction with a few conventions to
2733 simplify module writers' jobs. Also removed the table address
2734 caching code and otherwise simplified the module loader quite a
2735 bit. To access exported symbols in other modules, first the
2736 exporting module must name the symbols <modname>_LTX_<symname>,
2737 and the importing module must define a function type called
2738 <symname>_func. The importer then adds
2739 M4_MODULE_IMPORT(<modname>, <symname>) at the top of any function
2740 that wishes to call out to the exported functions. Care must be
2741 taken that <symname> is non-NULL in the importing module incase
2742 M4_MODULE_IMPORT fails, but otherwise it can be called as if the
2743 definition was in the importers source. Study
2744 `modules/{gnu.c,m4.{c,h}' for a model example. At the moment,
2745 m4_module_import will attempt to automatically load a module
2746 required for symbol access if it is not loaded already.
2748 * TODO: Removed the items fixed in this delta.
2749 * m4/ltdl.c (lt_dlhandle_find): New function to find a handle by
2751 * m4/ltdl.h (lt_dlhandle_find): Declare it.
2752 * m4/module.c (m4_module_unload): Use it.
2753 * src/freeze.c (reload_frozen_state): Ditto.
2754 * m4/m4module.h (m4_export): Deleted. Removed all references.
2755 (M4_MODULE_IMPORT): New user convenience macro for importing
2756 arbitrary symbols from other modules.
2757 * m4/module.c (m4_module_import): New function to service
2758 M4_MODULE_IMPORT macro.
2759 (module_data): Removed. Looking up the tables on demand with
2760 lt_dlsym, rather than caching their addresses here simplifies the
2762 (m4_get_module_builtin_table, m4_get_module_macro_table):
2763 Removed. Changed all callers.
2764 (set_module_macro_table, set_module_builtin_table): Renamed to
2765 install_macro_table and install_builtin_table respectively, and
2766 simplified now that the cache is no more.
2767 * modules/gnu.c (builtin_symbols): Use this new mechanism to
2768 import m4_dump_symbols from the m4 module.
2769 (builtin_esyscmd): Likewise for m4_set_sysval and
2771 * modules/m4.c (m4_export_table): Removed. Functions are
2772 addressed with the new mechanism which doesn't need this.
2773 (m4_set_sysval): New exported accessor function to prevent
2774 problems with variable access on inferior architectures.
2775 * modules/m4.h (m4_sysval_flush_func, m4_set_sysval_func)
2776 (m4_dump_symbols_func): Typedefs required by M4_MODULE_IMPORT so
2777 that we can have some type safety.
2778 * modules/modtest.c (export_test): C level exported function for
2779 testing the new import mechanism.
2780 * modules/import.c: New file for the import end of the test.
2781 * modules/Makefile.am (pkglibexec_LTLIBRARIES): Added import.la.
2782 * tests/modules.at: New test cases for intermodule symbol
2785 2003-08-07 Gary V. Vaughan <gary@gnu.org>
2787 * m4/m4module.c (m4_string): Moved from here...
2788 * m4/m4private.c (m4_string): ...to here.
2790 * m4/utility.c (dumpdef_cmp): Removed stale declaration.
2792 2003-07-29 Gary V. Vaughan <gary@gnu.org>
2794 * m4/m4module.h (M4_DEFAULT_NESTING_LIMIT): This value is
2795 already available to module writers through
2796 m4_{get,set}_nesting_limit_opt(), so moved from here...
2797 * m4/m4.c (DEFAULT_NESTING_LIMIT): ...to here and renamed.
2798 (m4_create): Use it.
2800 2003-07-28 Gary V. Vaughan <gary@gnu.org>
2802 Aside from auditing path.c for m4module.h api obfuscation, this
2803 delta introduces the concept of private struct members in opaque
2804 data types to GNU m4: See the STYLE file for details.
2806 * TODO: Remind ourselves that a rewrite of path.c is needed.
2807 * m4/m4module.h (m4_search_path, struct m4_search_path_info):
2809 * m4/m4private.h (m4__search_path, m4__search_path_info): ...to
2810 here and renamed. These type definitions are for internal api use
2811 only. Changed all callers.
2812 * m4/m4module.h (m4_search_path_env_init, m4_search_path_add):
2814 * m4/path.c (search_path_env_init, search_path_add): ...to here
2815 and renamed. These calls were never used outside this file.
2816 Changed all callers.
2817 (dirpath): Moved functionality of this static declaration...
2818 * m4/m4private.h (struct m4): ...to this new internal only
2819 search_path field. Changed all callers.
2820 (m4__get_search_path): Added new internal api accessor.
2821 * m4/path.c (m4_search_path_info_new): Removed. Not used.
2822 (m4_include_init): Removed...
2823 * m4/m4.c (m4_create): ...because the new m4 field is now
2825 (m4_delete): Recycle search_path memory.
2826 * src/main.c (main): Don't call m4_include_init now that it's
2828 * doc/STYLE: Document convention for private fields in opaque
2831 2003-07-24 Gary V. Vaughan <gary@gnu.org>
2833 Sometimes exporting the address of a symbol from a module isn't
2834 enough for other modules to call that symbol correctly. If
2835 custom data types are used for function parameters, they need to
2836 be known to the caller. This change introduces the concept of
2837 $(prefix)/include/modules/$(modulename).h to declare those
2838 structures. Also we move m4_dump_symbols from libm4 to the m4
2839 module to show this concept in action.
2841 * m4/m4module.h (m4_dump_symbol_data): Moved from here...
2842 * modules/m4.h (m4_dump_symbol_data): ...to this new file for
2843 exporting data structures from modules/m4.c.
2844 * modules/m4.c, modules/gnu.c: Include it.
2845 * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
2846 * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
2848 * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
2850 * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
2851 ...to here, with slight renaming.
2852 (m4_export_table): Prototype and add m4_dump_symbols.
2853 * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
2854 definition of m4_dump_symbols.
2855 * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
2856 * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
2858 2003-07-24 Gary V. Vaughan <gary@gnu.org>
2860 Create an export table in modules/m4.c in readiness for beefing up
2861 the module loader to track module exports and imports.
2863 * m4/m4module.h (m4_debug_flush_files): Removed prototype.
2864 * m4/debug.c (m4_debug_flush_files): Moved...
2865 * modules/m4.c (m4_sysval_flush): ...to here and renamed.
2866 * modules/gnu.c (builtin_esysval): Use it.
2867 * m4/m4module.h (m4_export): New type for declaring module symbols
2869 * modules/m4.c (m4_export_table): List symbols exported from this
2870 module for use by other modules.
2872 2003-07-24 Gary V. Vaughan <gary@gnu.org>
2874 An experiment: There is loads of code in libm4 which should be in
2875 the m4 module, but is also used by another module. Just because
2876 some linkers won't cope with calls across dynamic runtime loaded
2877 objects I initially left the code in libm4. It will tidy the
2878 module api immensely if this code moves to the right place, I just
2879 need to remember to invent a suitable calling mechanism at some
2880 point. For now, only modules that are statically linked and
2881 preloaded will get this treatment, so the only platforms that will
2882 break are those that require all symbols to be resolved at link
2885 * TODO: Reminder that what I am doing could reduce portability
2886 unless I do something more robust later.
2887 * m4/m4module.h (m4_sysval): No longer exported from libm4.
2888 * m4/utility.c (m4_sysval): No longer declared in libm4.
2889 * modules/Makefile.am: Reformatting.
2890 * modules/m4.c (m4_sysval): Declare it at place of use.
2891 * modules/gnu.c (m4_sysval): Import it for use in esyscmd.
2893 2003-07-23 Gary V. Vaughan <gary@gnu.org>
2895 * m4/m4module.h: Reformatting and rearranging lines a bit.
2896 (m4_obstack): Save typing by typedefing `struct obstack'. Changed
2898 (m4_call_macro, m4_expand_input): Renamed...
2899 (m4_macro_call, m4_macro_expand_input): ...to these. Changed all
2901 (m4_expansion_level, m4_process_macro): Moved...
2902 * m4/macro.c (expansion_level, process_macro): ...to here, and
2905 * m4/m4module.h (program_name): Not used by modules at all, so
2907 * src/main.c (program_name): ...to here.
2908 (print_program_name): Renamed...
2909 (print_program_name_CB): ...to conform to the STYLE guide.
2911 2003-07-23 Gary V. Vaughan <gary@gnu.org>
2913 More refactoring of the m4module.h API. Replace #defines with an
2914 enum, and move non-public functions out of the public API.
2916 * m4/debug.c (stdarg.h, varargs.h): Remove variadic header
2918 * m4/macro.c (stdarg.h): Add ANSI C variadic header.
2919 * m4/debug.c (m4_debug, trace): Moved...
2920 * m4/m4private.h (struct m4): ...to fields of this struct.
2921 (m4_get_debug_file, m4_get_trace_messages): New fast access macros
2923 * m4/debug.c (m4_debug_init, m4_debug_exit): Removed functions...
2924 * src/main.c (m4_debug_init, m4_debug_exit): ...invocations...
2925 * m4/m4.c (m4_create, m4_delete): ...and handled here instead.
2926 * m4/m4module.h (m4_context_field_table): Add entries for new
2927 debug_file and trace_messages fields.
2928 (M4_DEBUG_TRACE_ARGS, M4_DEBUG_TRACE_EXPANSION)
2929 (M4_DEBUG_TRACE_QUOTE, M4_DEBUG_TRACE_ALL, M4_DEBUG_TRACE_LINE)
2930 (M4_DEBUG_TRACE_FILE, M4_DEBUG_TRACE_PATH, M4_DEBUG_TRACE_CALL)
2931 (M4_DEBUG_TRACE_INPUT, M4_DEBUG_TRACE_CALLID)
2932 (M4_DEBUG_TRACE_VERBOSE): Replaced #defines with an enum.
2933 (m4_is_debug_bit): New macro to simplfy checks against the debug
2935 (m4_trace_format, m4_trace_header, m4_trace_flush)
2936 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Removed
2938 * m4/debug.c (m4_trace_format, m4_trace_header, m4_trace_flush)
2939 (m4_trace_prepre, m4_trace_pre, m4_trace_post): Moved...
2940 * m4/macro.c (trace_format, trace_header, trace_flush)
2941 (trace_prepre, trace_pre, trace_post): ...to these newly static
2942 functions, since they are only ever used from this file. Changed
2945 2003-07-17 Gary V. Vaughan <gary@gnu.org>
2947 Change the macros for checking syntax so that matching against
2948 multiple possible syntax classes can be done with a single
2949 comparison some of the time. The various classes are now bits of
2950 an int that can be checked with bitwise logic operators.
2952 * m4/m4module.h (M4_SYNTAX_IGNORE, M4_SYNTAX_OTHER)
2953 (M4_SYNTAX_SPACE, M4_SYNTAX_OPEN, M4_SYNTAX_CLOSE, M4_SYNTAX_COMMA)
2954 (M4_SYNTAX_DOLLAR, M4_SYNTAX_ACTIVE, M4_SYNTAX_ESCAPE)
2955 (M4_SYNTAX_ASSIGN, M4_SYNTAX_ALPHA, M4_SYNTAX_NUM)
2956 (M4_SYNTAX_LQUOTE, M4_SYNTAX_RQUOTE, M4_SYNTAX_BCOMM)
2957 (M4_SYNTAX_ECOMM): Replaced #defines with an enum.
2958 (M4_SYNTAX_ALNUM): Removed. Changed all callers.
2959 (M4_IS_IGNORE, M4_IS_OTHER, M4_IS_SPACE, M4_IS_OPEN, M4_IS_CLOSE)
2960 (M4_IS_COMMA, M4_IS_DOLLAR, M4_IS_ACTIVE, M4_IS_ESCAPE)
2961 (M4_IS_ASSIGN, M4_IS_ALPHA, M4_IS_NUM, M4_IS_LQUOTE, M4_IS_RQUOTE)
2962 (M4_IS_BCOMM, M4_IS_ECOMM, M4__IS_STRING, M4_IS_IDENT): Removed.
2963 Replace all calls with invocations of these...
2964 (m4_is_syntax, m4_has_syntax): ...New macros.
2965 * src/freeze.c (produce_syntax_dump): Remove mask argument, which
2966 is no longer required with new macros. Changed all callers.
2968 2003-07-15 Gary V. Vaughan <gary@gnu.org>
2970 * m4/input.c (CHAR_EOF, CHAR_BUILTIN, CHAR_RETRY): These token
2971 values are returned as part of the internal interface, so they
2973 * m4/private.h: ...to here.
2974 * m4/macro.c (expand_token): Check for out of range
2975 m4_peek_input() results before looking up in the syntax table.
2976 (collect_arguments): Ditto.
2978 * NEWS: Note `$' syntax class.
2980 2003-07-08 Paul Eggert <eggert@twinsun.com> and
2981 Gary V. Vaughan <gary@gnu.org>
2983 Conform to POSIX if the POSIXLY_CORRECT environment is set.
2984 --traditional `define' now smashes all the definitions.
2986 * NEWS: Explain this.
2987 * doc/m4.texinfo (Defn): `defn' takes any number of arguments.
2988 (Extensions): Explain that extensions that are incompatible with
2989 POSIX are disabled if POSIXLY_CORRECT is set.
2990 (Incompatibilities): Remove.
2991 (Define, Other Incompat): Explain difference
2992 between GNU and POSIX behavior of define, pushdef, popdef.
2993 * m4/m4.c (m4_get_posixly_correct_opt): New undef.
2994 * m4/m4module.h (m4_context_opt_bit_table): Add POSIXLY_CORRECT entry.
2995 * m4/m4private.h (M4_OPT_POSIXLY_CORRECT_BIT): New macro.
2996 (m4_get_posixly_correct_opt): New macro.
2997 * m4/m4macro.c (m4_process_macro): Disable $10, $abc etc. if
2999 * modules/m4.c (builtin_functions): defn now takes any number of args.
3000 (builtin_define): Smash all the definitions if
3002 (builtin_defn)): Allow any number of arguments.
3003 (builtin_undivert): Do not allow nonnumeric arguments
3005 * src/main.c (main): Set posixly-correct behavior if either
3006 POSIXLY_CORRECT is set, or if -G is given.
3007 * tests/builtins.at: New test for smashed definitions.
3009 2003-06-27 Gary V. Vaughan <gary@gnu.org>
3011 * doc/m4.texinfo (Changesyntax): Document Dollar syntax class.
3012 * m4/m4module.h (M4__SYNTAX_STRING): New syntax class. Be careful
3013 not to slow the parser down.
3014 (M4__IS_STRING): New macro to test string syntax class membership.
3015 * m4/syntax.c: Adjust docucomment.
3016 (m4_syntax_create): Add a default M4_SYNTAX_DOLLAR element.
3017 (m4_syntax_code): Translate `$' -> M4_SYNTAX_DOLLAR.
3018 * m4/input.c (init_builtin_token): Comment typo.
3019 (m4__next_token): Comment typo.
3020 Accept M4_SYNTAX_DOLLAR items into M4_TOKEN_STRING type tokens
3021 by using the new M4__IS_STRING macro.
3022 * m4/macro.c (m4_process_macro): Use M4_IS_DOLLAR to test for
3023 variable references in macro expansions.
3025 * doc/m4.texinfo (Eregexp and Regexp): Typo.
3026 (Epatsubst and Patsubst): Typo.
3029 2003-06-26 Gary V. Vaughan <gary@gnu.org>
3031 Move the global variables that pertain to syntax to a new `struct
3032 m4_syntax_table', and then add one of these to `struct m4'. The
3033 ripple effect through the code to both change formerly global
3034 references, and make sure a suitable context is available in
3035 lexical scope is disproportionately large compared to the size of
3036 the change proper. This change is a large part of decoupling
3037 syntax.c from the rest of the code that uses it.
3039 * m4/m4private.h (struct m4): Add a syntax field.
3040 * m4/m4.c (m4_create): Initialise it,
3041 (m4_delete): Recycle it.
3042 (m4_get_symtab): Remove hand coded version...
3043 (m4_get_symbol_table): ...and generate this with cpp. Changed all
3045 * m4/m4module.h (m4_context_field_table): Add an extra field so we
3046 can generate m4_get_symbol_table. Add a new row for
3047 m4_get_syntax_table.
3048 (M4SYNTAX): Syntactic sugar for module writers.
3049 (m4_symtab): Renamed to m4_symbol_table. Changed all callers.
3050 (m4_syntax_table): New home for syntax related formerly global
3052 * m4/m4private.h (struct m4_syntax_table): Define it.
3053 * m4/input.c (m4_input_init): Initialisation of these formerly
3054 global variables moved...
3055 * m4/syntax.c (m4_syntax_create): ...to here.
3056 * m4/input.c (m4_input_exit): And similarly, recycling of the
3057 memory used by those values moved...
3058 * m4/syntax.c (m4_syntax_delete): ...to here.
3059 * m4/m4module.h (DEF_LQUOTE, DEF_RQUOTE, DEF_BCOMM, DEF_ECOMM):
3060 Moved to m4/m4private.h.
3061 * m4/syntax.c (m4_get_syntax_lquote, m4_get_syntax_rquote)
3062 (m4_get_syntax_bcomm, m4_get_syntax_ecomm)
3063 (m4_is_syntax_single_quotes, m4_is_syntax_single_comments)
3064 (m4_is_syntax_macro_escaped): New accessors for m4_syntax_table
3065 objects. Changed all callers that used to directly access the
3067 (m4__single_quotes, m4__single_comments, m4__use_macro_escape):
3068 Removed and incorporated into m4_syntax_table structure.
3069 * m4/utility.c (lquote, rquote, bcomm, ecomm): Ditto.
3070 * m4/syntax.c (m4_set_syntax): Now returns an error status,
3071 instead of requiring a `struct m4' to generate its own errors.
3072 Changed all callers.
3073 * src/main.c (main): Now that the syntax table is initialised as
3074 part of m4_create, we have to manually wipe the syntax entries if
3075 we are about to read a frozen file.
3077 2003-06-26 Gary V. Vaughan <gary@gnu.org>
3079 * doc/STYLE: Added notes on callback naming schemes.
3081 * m4/module.c (m4_set_module_macro_table)
3082 (m4_set_module_builtin_table): Declarations weren't changed when
3083 definitions were renamed on 2003-06-19.
3085 * m4/hash.c (m4_hash_resize): ifdefed out. This function is
3086 neither used nor particularly appropriate since it exposes the
3087 internal workings of the hash module. I haven't yet decided
3088 whether to remove it entirely.
3090 2003-06-20 Gary V. Vaughan <gary@gnu.org>
3092 Two related changes, and a huge knockon effect throughout the
3093 source: Moved the option variables out of global space and into
3094 `struct m4'; made `m4_symtab' a real datatype, so that its api
3095 is not marred passing `struct m4' around just so it can decide
3096 whether to keep traced symbol names or not. Added setters and
3097 getters for the formerly global option variables, and obviously
3098 changed a vast number of functions to take a `struct m4' and use
3099 the getter funcs to find option values.
3101 * m4/utility.c (interactive, sync_output, debug_level)
3102 (no_gnu_extensions, prefix_all_builtins, suppress_warnings)
3103 (max_debug_argument_length, warning_status, nesting_limit)
3104 (discard_comments): Removed.
3105 * m4/m4module (warning_status, no_gnu_extensions, nesting_limit)
3106 (debug_level, max_debug_argument_length, prefix_all_builtins)
3107 (suppress_warnings, discard_comments, interactive, sync_output):
3108 Removed from here...
3109 * m4/m4private.h (struct m4): ...and equivalent fields added to
3111 (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
3112 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
3113 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
3114 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
3115 (m4_get_interactive_opt, m4_get_sync_output_opt): Fast access
3116 macros for the new fields.
3117 * m4/m4module.h (m4_context_field_table)
3118 (m4_context_opt_bit_table): Helper macros used to generate
3119 prototypes, setters and getters for new option fields
3121 * m4/m4.c (m4_get_warning_status_opt, m4_get_no_gnu_extensions_opt)
3122 (m4_get_nesting_limit_opt, m4_get_debug_level_opt)
3123 (m4_get_max_debug_arg_length_opt, m4_get_prefix_builtins_opt)
3124 (m4_get_suppress_warnings_opt, m4_get_discard_comments_opt)
3125 (m4_get_interactive_opt, m4_get_sync_output_opt)
3126 (m4_set_warning_status_opt, m4_set_no_gnu_extensions_opt)
3127 (m4_set_nesting_limit_opt, m4_set_debug_level_opt)
3128 (m4_set_max_debug_arg_length_opt, m4_set_prefix_builtins_opt)
3129 (m4_set_suppress_warnings_opt, m4_set_discard_comments_opt)
3130 (m4_set_interactive_opt, m4_set_sync_output_opt): Addressable
3131 setter and getter functions generated by cpp from
3132 m4_context_field_table and m4_context_opt_bit_table, exported as
3133 part of the module api. Changed all callers.
3134 * m4/symtab (struct m4_symtab): Used as the concrete type for
3136 (m4_symtab_create): Allocate and initialise a new struct.
3137 (m4_symtab_apply): New function that works like m4_hash_apply, but
3138 with different callbacks specific to symbol tables. Changed all
3140 (symbol_destroy, arg_destroy, arg_copy): Renamed
3141 symbol_destroy_CB, arg_destroy_CB, arg_copy_CB to remind me that
3142 they have unused parameters for a reason!
3143 (dump_symbol_CB): New callback to dump the contents of a single
3145 (symtob_dump): Rewritten in terms of dump_symbol_CB.
3146 * m4/utility.c (m4_dump_symbol): Renamed to m4_dump_symbol_CB.
3147 Changed all callers.
3148 * m4/m4.c (m4_create): By default point the `nuke_trace_bit' field
3149 of the contained `m4_symtab' at the `no_gnu_extensions' field.
3150 Although I'm not convinced these semantics are correct, they are
3151 at least consistent with how things were before this delta. Also
3152 set the default nesting limit to M4_DEFAULT_NESTING_LIMIT.
3154 2003-06-19 Gary V. Vaughan <gary@gnu.org>
3156 Tie down the interface to libm4 some more. Make more structures
3157 opaque to modules by moving them to m4private.h, and writing
3158 setters and getters. To win back the speed penalty for doing this
3159 also wrote macroized versions that do know about structure layout
3160 in m4private.h and #include that file into modules when NDEBUG is
3161 defined at compile time. There are still some accessor macros in
3162 m4private.h that need to go, but that is not necessary to clean
3165 * m4/m4module.h (m4_symbol_type): Moved...
3166 * m4/m4private.h (m4__symbol_type): ...to here.
3167 * m4/symtab.c (m4_get_symbol_value, m4_get_symbol_traced)
3168 (m4_set_symbol_traced, m4_set_symbol_name_traced)
3169 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)
3170 (m4_get_symbol_func, m4_symbol_value_create)
3171 (m4_symbol_value_delete, m4_set_symbol_value_text)
3172 (m4_set_symbol_value_func): New exported api to symbols.
3173 (m4_get_symbol_value_type): Replaced by m4_is_symbol_value_text
3174 and m4_is_symbol_value_func.
3175 * m4/m4module.h: Prototype these guys.
3176 * m4/module.c (m4_set_module_macro_table)
3177 (m4_set_module_builtin_table): Make these static, there is no
3178 reason to pollute the api with them.
3179 * m4/m4private.h: Reformatting.
3180 (m4_get_symtab): Only define when NDEBUG is defined.
3181 (m4_get_symbol_value, m4_get_symbol_traced)
3182 (m4_set_symbol_traced, m4_set_symbol_name_traced)
3183 (m4_is_symbol_text, m4_is_symbol_func, m4_get_symbol_text)

3185 (m4_symbol_value_delete, m4_set_symbol_value_text)
3186 (m4_set_symbol_value_func): Macro implementations of the new
3187 functions when NDEBUG is defined.
3188 (SYMBOL_TRACED, SYMBOL_VALUE, SYMBOL_TYPE, SYMBOL_TEXT)
3189 (SYMBOL_FUNC, VALUE_TYPE, VALUE_TEXT, VALUE_FUNC): Removed.
3190 Superceded by the above. All callers changed.
3191 (M4ARG): Removed. This is no longer different to the
3192 m4/m4module.h definition.
3193 * modules/gnu.c, modules/m4.c: Only include m4private.h when
3194 NDEBUG is defined. That way we exercise the same (albeit slower)
3195 api that external modules must use.
3197 2003-06-18 Gary V. Vaughan <gary@gnu.org>
3199 Renamed some of the types and their accessors to make more sense.
3200 Now we have a SYMTAB in which we store SYMBOLs, and each SYMBOL
3201 has a stack of SYMBOL_VALUEs.
3203 * m4/m4module.h (m4_token, m4_get_token_type, m4_get_token_text)
3204 (m4_get_token_func, m4_token_copy): Renamed to m4_symbol_value,
3205 m4_get_symbol_value_type, m4_get_symbol_value_text,
3206 m4_get_symbol_value_func and m4_symbol_value_copy respectively.
3207 Changed all callers.
3208 (m4_symbol_type): s/M4_TOKEN_/M4_SYMBOL_/
3209 (m4_get_token_type): Renamed
3210 * m4/input.c (m4_next_token): Renamed to m4__next_token, and moved
3211 to the internal api.
3212 * m4/m4private.h: s/TOKEN_ARG_/SYMBOL_ARG_/
3214 (m4__symtab_init, m4__symtab_exit): Removed prototypes.
3215 (m4_token_arg): Renamed to m4_symbol_arg. Changed all callers.
3216 (m4__token_type): Moved here from m4module.h.
3217 (m4__next_token): Renamed from m4_next_token.
3218 * m4/symtab.c: Removed some of the parameterised macro support
3219 functions for modularisation later.
3220 (m4_token_copy): Renamed to m4_symbol_value_copy, and use new
3221 m4_hash_dup to perform a true deep copy of the SRC.
3222 (arg_copy): Callback for m4_symbol_value_copy.
3223 * utility.c (m4_token_get_type, m4_token_text, m4_token_func):
3224 Renamed to m4_get_symbol_value_type, m4_get_symbol_value_text and
3225 m4_get_symbol_value_func. Changed all callers.
3227 2003-06-18 Gary V. Vaughan <gary@gnu.org>
3229 Tidy up style of hash.[ch] in accordance with doc/STYLE.
3231 * m4/hash.c: Internal symbol renaming and formatting.
3232 (m4_hash_dup): New function to facilitate deep copies of hash
3234 (m4_hash_apply_func): Returns a void* now, which is a richer type
3235 for returning exceptions (NULL means keep going).
3236 (m4_hash_apply): Ditto.
3237 * m4/hash.h: Declare exported symbols with an explicit extern.
3240 2003-06-17 Gary V. Vaughan <gary@gnu.org>
3242 Still refactoring furiously. This delta represents a change in
3243 semantics to symtab.c. Instead of building temporary m4_tokens
3244 in the caller, and copying fields in the methods, we now create
3245 the actual m4_token for hashing in the caller so the methods just
3246 slot them in directly. Also, this means that we don't lookup a
3247 symbol and get back an allocated but VOID token to copy fields
3248 into, we create the token we want to push and pass that to
3249 m4_symbol_define or m4_symbol_pushdef. And that's it. There are
3250 a few other small changes to stop knowledge of the implementation
3251 of symtab.c leaking out into other files.
3253 * m4/macro.c (expand_argument): Comment typo corrected.
3254 * m4/symtab.c (symtab_fetch): New function to fetch the address of
3256 (m4_symbol_pushdef): Take an extra value parameter and use this
3257 directly as the new top of the value stack. All callers changed
3258 to build a token and pass responsibility for memory in, rather
3259 than copying as we used to.
3260 (m4_symbol_define): Also use the new value parameter directly as a
3261 replacement for the top of the value stack. All callers changed
3262 to build a token as above.
3263 (m4_set_symbol_traced): New function to set the traced bit on the
3264 named symbol, creating it if necessary.
3265 (symbol_popval): The guts of the old m4_symbol_popdef.
3266 (m4_symbol_popdef): Use it.
3267 * m4/builtin.c (m4_symbol_set_token): Removed,
3268 (m4__symbol_set_builtin, m4__symbol_set_macro): Removed and
3270 * m4/module.c (m4_set_module_builtin_table)
3271 (m4_set_module_macro_table): ...with these more orthogonal
3273 * m4/m4module.h (m4_macro_pushdef, m4_macro_define)
3274 (m4_builtin_pushdef, m4_builtin_define): Removed. No longer
3276 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE)
3277 (m4_arg_signature_parse): Moved...
3278 * m4/symtab.c: ...to here.
3279 * m4/input.c (m4_token_copy): Arghh... I'm amazed this didn't
3280 screw something up. Moved...
3281 * m4/symtab.c (m4_token_copy): ...to here, and fixed so that it
3282 actually does a proper deep copy of source to dest.
3284 2003-06-16 Gary V. Vaughan <gary@gnu.org>
3286 Further refactoring to stabilise the module API. Renaming some
3287 functions for orthogonality, and judicious definition migration to
3288 move things out of the set of exported symbols.
3290 * doc/STYLE: New file. Notes on coding style.
3291 * m4/m4module.c: Updated bitrotted docucomment at the top of the
3293 (m4_module_name, m4_module_builtins, m4_module_macros): Renamed to
3294 m4_get_module_name, m4_get_module_builtin_table,
3295 m4_get_module_macro_table which are verb phrases. Changed all
3297 * m4/builtin.c (m4_builtin_table_install, m4_macro_table_install):
3299 * m4/module.c (m4_set_module_builtin_table)
3300 (m4_set_module_macro_table): ...here, and renamed. Changed all
3302 * m4/m4module.c (m4_module_data): This...
3303 * m4/m4private.c (struct m4_module_data): ...and this...
3304 * m4/module.c (module_data) ...consolidated here and no longer
3305 exported. Changed all callers.
3307 2003-06-16 Gary V. Vaughan <gary@gnu.org>
3309 Begin work on lifting the curse of the global variables. To start
3310 with create a `struct m4' context container, and replace
3311 `m4__symtab' with `context->symtab' throughout. This means
3312 initialising a context container in main, and adjusting many
3313 functions between main and the module entry points so that the
3314 container gets passed through. It would have been nice to
3315 defer this until after 1.5, but it has a major effect on the
3316 user's module writing ABI, so it needs to be addressed now - at
3317 least in the areas that impact the ABI. An interrelated change
3318 in the symtab API removes the dependency on a global symbol table,
3319 and instead focuses on a passed table (from the context
3322 * TODO: Reminders for finishing context functionality.
3323 * m4/Makefile.am (libm4_la_SOURCES): Add m4.c.
3324 * m4/m4.c: New file. Manage new struct m4 objects to eliminate
3325 global variables and eventually allow m4 to be reentrant.
3326 * m4/m4private.h (m4): Define the new structure here...
3327 (M4_SYMTAB, m4_get_symtab): ...so we can have fast accessors that
3328 don't carry the overhead of a function call.
3329 * m4/m4module.h: Prototype extern functions from m4/m4.c.
3330 (m4): Declare type for new struct m4 objects.
3331 (M4SYMTAB): User macro to ease finding the symbol table for the
3332 current context for module developers.
3333 (m4_symbol_token): Renamed to m4_symbol_set_token which contains a
3335 (M4_BUILTIN, m4_builtin_func, M4_BUILTIN_HANDLER)
3336 (m4_builtin_define, m4_builtin_pushdef, m4_builtin_table_install)
3337 (m4_call_macro, m4_dump_symbols, m4_expand_input)
3338 (M4_FINISH_HANDLER, M4_INIT_HANDLE, m4_macro_define)
3339 (m4_macro_pushdef, m4_macro_table_install, m4_module_load)
3340 (m4_module_unload, m4_process_macro, m4_symbol_set_token): Add an
3341 m4* context parameter. Changed definitions and all callers.
3342 (m4_symtab): Alias for m4_hash to decouple the
3343 m4_symtab api from m4_hash.
3344 (m4_symtab_apply, m4_symtab_apply_func): Use m4_symtab instead of
3346 (m4_symtab_create): New function to return an initialised
3348 (m4_symtab_delete): New function to delete an m4_symtab's memory.
3349 (m4_symbol_define, m4_symbol_delete, m4_symbol_lookup)
3350 (m4_symbol_popdef, m4_symbol_pushdef): Add an m4_symtab parameter
3351 instead of simply using the global m4__symtab. Changed
3352 definitions and all callers.
3353 * m4/m4private.h (m4__symtab_remove_module_references): Ditto.
3354 * m4/symtab.c (m4__symtab_init, m4__symtab_exit): Removed.
3355 * src/main.c (main): Create a context and use that instead of the
3356 former global m4__symtab.
3358 2003-06-13 Gary V. Vaughan <gary@gnu.org>
3360 * m4/hash.c (m4_hash_apply): Pass an initial hash table parameter
3361 to the callback. Callbacks should not need to hardcode the
3362 hashtable they are working from, nor should we have to waste the
3363 userdata parameter to pass the table in.
3364 * m4/hash.h (m4_hash_apply_func): Require the initial table
3366 * m4/symtab.c (symtab_destroy): Use the passed table instead
3367 of hardcoding m4__symtab.
3368 (m4_symbol_popdef): Don't use the userdata parameter to pass the
3369 table to arg_destroy.
3370 (arg_destroy): Use the hash parameter, ignore userdata.
3371 * modules/m4.c (set_trace): Make it fit the m4_hash_apply_func
3373 (traceon, traceoff): Call set_trace with the extra initial
3376 2003-06-13 Gary V. Vaughan <gary@gnu.org>
3378 More refactoring to stabilise the module api, this time for
3379 symtab.c. Additionally, start to pay attention to function names
3380 that don't contain a verb like they should.
3382 * m4/m4module.h (m4_symtab_apply): Reintroduced this function as a
3383 wrapper for m4_hash_apply to decouple the symtab module from the
3385 (m4_symbol_builtin, m4_symbol_macro): Renamed to
3386 m4__symbol_set_builtin and m4__symbol_set_macro. Changed all
3388 (m4_symbol_delete): Create a macro version to save a function
3390 (m4_token_t, m4_data_t): These violate the POSIX reserved
3391 namespace. Renamed to m4_token_type and m4_symbol_type. Changed
3393 (m4_token_type): Renamed to m4_token_get_type.
3394 (m4_symtab, m4_symtab_init, m4_symtab_remove_module_references)
3395 (m4_symtab_exit): Removed from the exported module
3397 * m4/m4private.h (m4__symtab, m4__symtab_init)
3398 (m4__symtab_remove_module_references, m4__symtab_exit): ...and
3399 renamed and added to the internal api. Changed all callers.
3400 (m4_symtab_apply): A faster macro version of the function for
3401 users of the internal api.
3402 * m4/symtab.c (m4_symbol_destroy, m4_arg_destroy): Renamed to
3403 symbol_destroy and arg_destroy.
3404 (symtab_debug): Added a prototype.
3405 (m4_symtab_apply, m4_symbol_delete): Moved to the end of the file
3406 so that callers in this file get the faster macro versions from
3409 2003-06-12 Gary V. Vaughan <gary@gnu.org>
3411 Refactoring modules to rationalise the API into an external
3412 documented (eventually!) API for use by modules in the `m4_'
3413 namespace declared in m4/m4module.h, an internal API between the
3414 source files we ship (including our shipped modules) in the `m4__'
3415 namespace declared in m4/m4private.h and making the rest as
3416 cohesive as possible with liberal use of the `static' keyword.
3417 This change represents an audit to m4/module.c along these
3420 * m4/m4module.h (m4_module_close_all, m4_module_find_by_builtin):
3421 Removed. No longer used.
3422 (m4_module_close): Removed prototypes.
3423 (m4_module_init, m4_module_open, m4_module_unload_all): Removed
3424 from the exported module api...
3425 * m4/m4private.h (m4__module_init, m4__module_open)
3426 (m4__module_exit): ...and renamed and added to the internal api.
3427 Changed all callers.
3428 (BUILTIN_SYMBOL, MACRO_SYMBOL, INIT_SYMBOL, FINISH_SYMBOL):
3429 Centralised definitions after renaming...
3430 * m4/module.c (M4_BUILTIN_SYMBOL, M4_MACRO_SYMBOL, M4_INIT_SYMBOL)
3431 (M4_FINISH_SYMBOL): ...and removing from here.
3432 (m4_module_dlerror, m4_module_remove, m4_module_close)
3433 (m4_caller_id): Not exported at all, so renamed to module_dlerror,
3434 module_remove, module_close and caller_id.
3435 (MODULE_SELF_NAME): New macro to make reporting self errors
3437 (m4_module_load, module_close, module_remove): Use it.
3438 * m4/m4private.h (USER_MODULE_PATH_ENV): Macro to hold "M4MODPATH"
3440 * src/main.c (main): Use it.
3442 2003-06-12 Gary V. Vaughan <gary@gnu.org>
3444 * README: Remove references to --enable-changeword, which has been
3445 removed from the code.
3447 2003-06-11 Gary V. Vaughan <gary@gnu.org>
3449 Getting rid of the annoying bug with configure --enable-debug,
3450 which spewed -e: command not found errors. This was an interaction
3451 between libtool-1.5's LT_AC_COMPILER_OPTION, and config/debug.m4.
3452 You'll need to re-bootstrap the m4 tree with cvs libtool (HEAD or
3453 branch-1-5) to get the full fix.
3455 * config/debug.m4 (M4_AC_CHECK_DEBUGGING): Require libtools version
3456 of AC_LIBTOOL_COMPILER_OPTION (which now requires LT_AC_PROG_SED),
3457 and then use the probed value of $SED.
3458 (AC_LIBTOOL_COMPILER_OPTION): Removed. Don't conditionally define
3459 this, it messes up the AC_REQUIRE stack.
3461 2003-06-10 Gary V. Vaughan <gary@gnu.org>
3463 * m4/symtab.c (m4_symbol_popdef): Need to pass the hash address to
3464 the destroy callback.
3465 (m4_arg_destroy): Use the hash address to free the hash node key
3468 2003-06-06 Gary V. Vaughan <gary@gnu.org>
3470 First cut at formal parameters in macros.
3472 * configure.ac (AC_REPLACE_FUNCS): Add xstrzdup.
3473 * m4/xstrzdup.c: New file.
3474 * m4/builtin.c (M4_ARG_SIGNATURE_DEFAULT_SIZE): Start size for
3475 associative array of parameter names to details.
3476 (m4_symbol_token): Capture macro names with parameter lists.
3477 (m4_arg_signature_parse): And build an associative array to hang
3478 from the symbol structure to map names to details.
3479 * m4/hash.c (m4_hash_new): Break the m4_hash_new followed by
3480 m4_hash_resize idiom. Now that we potentially add a little hash
3481 table to many of the entries in the symbol table, added an extra
3482 arg to set the initial size. Changed all callers.
3483 (m4_hash_apply): New function that is basically a generalised
3485 * m4/symtab.c (m4_symbol_apply): ...this. Now deleted. Adjusted
3486 all callers to call m4_hash_apply instead.
3487 (m4_arg_destroy): Recycle memory used by an m4_token_arg.
3488 (m4_symbol_popdef): Use m4_arg_destroy to help recycle the
3489 m4_arg_signature association that might be attached to the symbol,
3490 * m4/hash.h (m4_hash_apply_func): Replacement type for...
3491 * m4/m4module.h (m4_symtab_apply_func): ...this. Now deleted.
3492 (M4_SYNTAX_ASSIGN): Placeholder for assigning default values in
3494 (M4_IS_ASSIGN): Detect characters with M4_SYNTAX_ASSIGN syntax.
3495 (M4_IS_IDENT): Detect characters that can be safely used in
3497 * m4/syntax.c (m4_syntax_init): Add an M4_SYNTAX_ASSIGN character.
3498 * m4/macro.c: Corrected grammar in some comments. Use `token'
3499 rather than `td' for m4_token variables.
3500 (m4_process_macro): If we find a dollar followed by some
3501 M4_IS_IDENT characters, replace that with the contents of the argv
3502 entry with offset stored in the m4_token_arg associated with the
3503 collected identifier.
3505 2003-06-05 Gary V. Vaughan <gary@gnu.org>
3507 Begin preparations for supporting formal parameters in m4 macros.
3509 * m4/m4private.h (struct m4_token_arg): Placeholder for holding
3510 the details of a formal parameter.
3511 (m4_token): Add an arg_signature member to hold a hash table for
3512 looking up formal parameters.
3513 * m4/input.c: Update more bitrotted comments.
3514 (m4_push_builtin): Initialise arg_signature member.
3515 (init_builtin_token): Copy arg_signature member.
3516 * m4/m4module.h (m4_builtin_pushdef, m4_builtin_define)
3517 (m4_macro_pushdef, m4_macro_define): Rewritten as macros to
3519 * m4/builtin.c (m4_builtin_pushdef, m4_builtin_define)
3520 (m4_macro_pushdef, m4_macro_define): ...these, And...
3521 (m4_symbol_token): ...wrapped around this new function, which
3522 vastly simplifies the arguments required by the functions it
3524 Changed all callers.
3526 2003-06-05 Gary V. Vaughan <gary@gnu.org>
3528 * m4/macro.c: Format changes.
3530 2003-06-04 Gary V. Vaughan <gary@gnu.org>
3532 * m4/input.c: Updated various bitrotted comments.
3533 (m4_push_builtin): Just pass the whole m4_token, rather than
3534 extracting all the fields in the caller. This also allows us to
3535 check the token type for consistency.
3536 (macro_funcs, macro_peek, macro_read, m4_push_macro, CHAR_MACRO):
3537 Renamed to builtin_funcs, builtin_peek, builtin_read,
3538 m4_push_builtin and CHAR_BUILTIN for consistency with the rest of
3539 the code. Changed all callers.
3540 (struct input_block): Similarly renamed u_m member to u_b, and
3541 changed all callers.
3542 (m4_next_token): Use bzero to initialise the data fields.
3543 * m4/m4module (m4_push_macro): Renamed to m4_push_builtin.
3545 2003-05-29 Gary V. Vaughan <gary@gnu.org>
3547 These changes were necessary to get m4 to build on my iBook
3548 running "powerpc-apple-darwin6.6" using Apples build of gcc "gcc
3549 (GCC) 3.1 20020420 (prerelease)":
3551 * src/main.c: Don't include dlfcn.h, ltdl.h handles correct
3552 inclusion of module loader headers.
3553 * modules/Makefile.am: Use AM_LDFLAGS, not LDFLAGS.
3554 * m4/Makefile.am: Ditto.
3555 (libm4_la_LIBADD): Added $(LTLIBINTL).
3556 * m4/utility.c (program_name): Removed declaration in favour of
3557 the one already in error.c!
3558 * m4/m4module.h (program_name): Define to program_invocation_name
3559 when using GNU C library. Use an explicit extern declaration.

3585 * po/quot.sed: New file, from gettext-0.11.5.

3587 * po/Rules-quot: New file, from gettext-0.11.5.
3589 2002-11-04 Akim Demaille <akim@epita.fr>
3591 * doc/m4.texinfo (Esyscmd): Don't grep, use something easier:
3593 * tests/others.at (iso8859): Use abs_srcdir, not srcdir.
3595 2002-11-04 Akim Demaille <akim@epita.fr>
3597 * config/Makefile.am (ACLOCAL_MACROS): Ship the Gettext macros.
3599 2002-11-04 Akim Demaille <akim@epita.fr>
3601 * configure.ac: Automake 1.7.1, Autoconf 2.54, Gettext 0.11.5,
3602 used as `external', and Libtool 1.4.3.
3604 (LTLIBOBJS): Don't play with it.
3606 * Makefile.am (SUBDIRS): Remove intl.
3607 (ACLOCAL_AMFLAGS): Add -I config.
3608 (EXTRA_DIST): Add config/config.rpath.
3611 * modules/perl.c (M4INIT_HANDLER): Don't prototype xs_init.
3613 2002-05-29 Gary V. Vaughan <gary@gnu.org>
3615 Preparations for refactoring syntax tables to allow reverse
3616 lookups [fetch me a M4_SYNTAX_OPEN], without compromising the
3617 speed of normal lookups in an array of unsigned short.
3619 * m4/input.c (single_quotes, single_comments, use_macro_escape):
3621 * m4/m4private.h (m4__single_quotes, m4__single_comments,
3622 m4__use_macro_escape): ...to here, and renamed. The `m4__' prefix
3623 is for internal symbols which unavoidably pollute the global
3624 namespace, but are not published APIs.
3625 Adjusted all callers.
3626 * m4/input.c (m4_syntax_init, m4_syntax_code, m4_set_quotes,
3627 m4_set_comment, m4_set_syntax, set_syntax_internal,
3628 unset_syntax_attribute): Moved from this file...
3629 * m4/syntax.c: New. ...to this file.
3630 Also added an m4_syntax_exit stub for orthogonality.
3631 * src/main.c (main): Use it.
3632 * m4/Makefile.am (libm4_la_SOURCES): Add syntax.c.
3633 * m4/m4module.h: Reformatting. New prototypes.
3635 2002-05-29 Gary V. Vaughan <gary@gnu.org>
3637 * bootstrap (aclocal_apiversion): The aclocal apiversion is
3638 distinct from the automake release number (in that the apiversion
3639 apparently has no micro-version-component).
3640 (aclocal_apilibdir): Use it.
3642 2002-05-28 Gary V. Vaughan <gary@gnu.org>
3644 * m4/hash.c (m4_hash_resize): New function.
3645 * m4/hash.h: Add prototype.
3646 * m4/symtab.c (m4_symtab_init): Use it. This could do with some
3647 benchmarking to find a good value for, say, autoconf. This is
3648 already a little quicker than before for me.
3650 * m4/symtab.c (m4_symtab_hash, m4_symtab_cmp): Moved from here...
3651 * m4/hash.c (m4_hash_string_hash, m4_hash_string_cmp): .. to here,
3653 * m4/hash.h: Adjust prototypes.
3655 2002-01-22 Akim Demaille <akim@epita.fr>
3657 * bootstrap (aclocal_apilibdir): New, to cope with Automake's new
3659 * tests/Makefile.am (package.m4): New.
3660 * tests/atlocal.in: Adjust to CVS Autotest.
3661 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Use AC_LIBOBJ.
3662 * configure.ac: LIBOBJ is a forbidden string.
3663 Simplify AM_INIT_AUTOMAKE invocation.
3664 * config/Makefile.am (ACLOCAL_MACROS): Add amversion.m4 and
3667 2002-01-21 gettextize <bug-gnu-utils@gnu.org>
3669 * po/Makefile.in.in: Upgrade to gettext-0.10.40.
3671 2001-10-19 Akim Demaille <akim@epita.fr>
3673 * m4/module.c, m4/output.c, src/main.c: Normalize error messages.
3675 2001-10-19 Akim Demaille <akim@epita.fr>
3677 * m4/input.c (m4_next_token): Display where was opened what is
3680 2001-10-19 Akim Demaille <akim@epita.fr>
3682 * m4/macro.c (expand_argument): Display where was opened what is
3685 2001-10-18 Akim Demaille <akim@epita.fr>
3687 * m4/input.c, modules/m4.c: Formatting changes.
3689 2001-10-17 Gary V. Vaughan <gary@gnu.org>
3691 * bootstrap: s/configure.in/configure.ac/
3693 2001-10-16 Gary V. Vaughan <gary@gnu.org>
3695 * m4/symtab.c (m4_symbol_destroy): This function calls
3696 m4_symbol_popdef, which recycles a symbols memory when the last
3697 definition is popped. Since we were passing the address of the
3698 symbol name found in the symbol table, and it was being removed
3699 partway through m4_symbol_destroy() we were referencing freed
3700 memory for the balance of the function. Now we take a copy of the
3701 symbol name tring and use that as a key into the symbol
3702 table... that way if the original symbol name is freed, the copy
3705 2001-10-13 Akim Demaille <akim@epita.fr>
3707 * m4/ltdl.c: Update.
3709 2001-10-13 Akim Demaille <akim@epita.fr>
3711 * src/main.c, src/freeze.c, m4/debug.c, m4/input.c, m4/macro.c:
3712 Don't gettextize internal error messages.
3714 2001-10-13 Akim Demaille <akim@epita.fr>
3716 * tests/macros.at (Arity and defn): New failing test.
3717 (Arity, defn, and freeze): New.
3719 Fix `Arity and defn'.
3721 * m4/input.c (m4_push_macro): Don't forget the arity.
3722 * modules/m4.c (defn): Likewise.
3724 2001-10-13 Akim Demaille <akim@epita.fr>
3726 * tests/builtins.at (pushdef/popdef, trace, trace2, trace3): Move
3728 * tests/macros.at (pushdef/popdef, Tracing Hanoi Towers)
3729 (Propagation of traceon, Propagation of --trace): this new file.
3731 2001-10-13 Akim Demaille <akim@epita.fr>
3733 * m4/utility.c (m4_numeric_arg): Use the usual (argc, argv, ...)
3734 interface instead of (name, argc...).
3735 Upon failure, specify which argument was guilty.
3738 2001-10-13 Akim Demaille <akim@epita.fr>
3740 * modules/evalparse.c: Save translators' time: don't translate
3741 internal error messages.
3742 (m4_evaluate): Simplify/normalize error messages.
3743 * doc/m4.texinfo (Eval): Adjust.
3745 2001-10-13 Akim Demaille <akim@epita.fr>
3747 * m4/macro.c (expand_macro): Let m4_bad_argc handle the cases
3748 where no checking is needed.
3749 * m4/utility.c (m4_bad_argc): Use the usual (argc, argv, ...)
3750 interface instead of (name, argc...).
3752 * modules/gnu.c (m4_patsubst_do): Don't check argc, done
3755 2001-10-13 Akim Demaille <akim@epita.fr>
3757 * m4/utility.c (m4_bad_argc): Display user argument counts, i.e.,
3758 exclude the builtin name from the count.
3759 * modules/m4.c (ifelse): Do not use the regular argc mechanism, as
3760 calling ifelse with a single argument is valid.
3761 * doc/m4.texinfo (Ifelse): Add an example where ifelse is invoked
3762 with 1 and 2 args, mostly to strengthen the test suite.
3764 2001-10-13 Akim Demaille <akim@epita.fr>
3766 * m4/output.c (m4_make_diversion, m4_insert_file)
3767 (m4_insert_diversion, +m4_freeze_diversions): Ansify.
3769 2001-10-12 Gary V. Vaughan <gary@gnu.org>
3771 * m4/input.c (init_builtin_token): Renamed from init_macro_token,
3772 since we call these things builtins in the rest of the code!
3774 * modules/gnu.c (m4_regexp_compile): s/%0/%s/
3776 2001-10-12 Gary V. Vaughan <gary@gnu.org>
3778 Rather than forcing each builtin definition to manage its own
3779 argument range checking, tabulate the maxima and minima for all
3780 builtins in each module. This forces us to consider what the
3781 valid ranges for each builtin should be, and moves the checking
3782 code out of each builtin implementation and into the builtin
3783 caller infrastructure.
3785 * m4/m4module.h (struct m4_builtin): Add argument minima and
3787 * m4/m4private.h (struct m4_token): Reflect them here too.
3788 * m4/input.c (struct input_block): ...and here.
3789 (m4_token_copy): New function for token copying.
3790 (init_macro_token): Copy them from a token to the input stack.
3791 (m4_next_token): Don't forget to initialise them for text
3793 * m4/macro.c (expand_argument): Use m4_token_copy, and also
3794 check argument counts before calling the builtin handler.
3795 * m4/symtab.c (m4_symbol_builtin): Take minima and maxima params.
3796 (m4_symbol_macro): Likewise.
3797 * m4/builtin.c (m4_builtin_pushdef): Add min_args and max_args
3798 parameters. Updated all callers.
3799 (m4_builtin_define): Ditto.
3800 (m4_macro_pushdef, m4_macro_define): Ditto.
3801 * m4/symtab.c (m4_symbol_builtin, m4_symbol_define): Ditto.
3802 * modules/evalparse.c: Declare argument counts for defined
3803 builtins and remove explicit calls to m4_bad_argc().
3804 * modules/gnu.c: Ditto.
3805 * modules/load.c: Ditto.
3806 * modules/m4.c: Ditto.
3807 * modules/modtest.c: Ditto.
3808 * modules/mpeval.c: Ditto.
3809 * modules/perl.c: Ditto.
3810 * modules/shadow.c: Ditto.
3811 * modules/stdlib.c: Ditto.
3812 * modules/time.c: Ditto.
3815 2001-10-10 Gary V. Vaughan <gary@gnu.org>
3817 The trace semantics now attach the trace bit to a symbol name.
3818 For as long as a traceon(`foo') is active, calls to foo will be
3819 traced regardless of intervening undefines or module unloads.
3820 Fixed the flag propogation issues differently to the fixes
3821 reverted with the last attempt at nailing down trace:
3823 * m4/m4private.h: This file is not visible outside of the m4
3824 source tree, so I removed all the `M4_' and `m4_' prefixes to save
3825 on typing. Updated all clients.
3826 (m4_token): New typedef contains the fields that need to be passed
3827 around with the low level tokeniser.
3828 (m4_token_data): Removed.
3829 (m4_symbol): Now contains the traced flag again.
3830 * m4/symtab.c: Rewritten again. Now we don't remove symbols with
3831 the trace bit set. This change is contained entirely within this
3832 module and doesn't leak out into the callers. Updated all
3834 (m4_symbol_builtin, m4_symbol_macro): Adjusted to make use of the
3835 new fields in m4_token. Updated all clients.
3836 * m4/builtin.c (m4_builtin_pushdef): Needs a flags argument so
3837 that `groks_macro_args' and `blind_if_no_args' flags are retained
3838 when defn() results are passed around in m4 code. Updated all
3840 (m4_builtin_define): Ditto.
3841 (m4_macro_pushdef, m4_macro_define): Ditto.
3842 * m4/input.c (struct input_block): Add a flags field to facilitate
3844 (m4_push_macro): ...use it.
3845 (init_macro_token): Retrieve it.
3846 (m4_next_token): Initialise it.
3847 * m4/macro.c (expand_argument): Copy it.
3848 * m4/m4module.h: Adjust.
3849 * tests/builtins.at: Adjust the expected output of the trace
3850 tests to reflect the change in semantics.
3851 * tests/modules.at (modules: trace): Check that unloading a
3852 module which supplies a traced symbol definition doesn't lose te
3855 2001-10-07 Gary V. Vaughan <gary@gnu.org>
3857 * modules/gnu.c (m4_macro_table): Display the timetamp when
3858 expanding __m4_version__.
3860 * configure.ac (--with-modules): Forgot a comma in the
3861 AC_HELP_STRING parameter list.
3863 2001-10-05 Gary V. Vaughan <gary@gnu.org>
3865 * bootstrap: Remove aclocal.m4t when it is no longer required.
3867 2001-10-05 Akim Demaille <akim@epita.fr>
3869 * tests/Makefile.am: Adjust for gnuprog2.
3870 * tests/m4.in: There can be a leading path.
3871 * tests/modules.at (AT_CHECK_M4_MODTEST): No need for $4 and $5.
3872 * tests/testsuite.at: Adjust to the most recent Autotest.
3873 (AT_CHECK_M4_FILTER): Fix and rename as...
3875 * tests/others.at: Use it.
3877 * config/gmp.m4 (_AC_LIB_GMP): In order to read the content of a
3878 variable in shell scripts, one uses `$'...
3880 2001-10-04 Gary V. Vaughan <gary@gnu.org>
3882 * configure.ac: `rm -f $m4_getopt_h' was lost.
3884 2001-10-04 Gary V. Vaughan <gary@gnu.org>
3886 * configure.ac (TIMESTAMP): Display with AS_BOX at configure
3887 time. Define it for config.h in order to...
3888 * src/main.c (main): ...display the timestamp for --version.
3890 2001-10-04 Akim Demaille <akim@epita.fr>
3892 * modules/gnu.c (m4_regexp_do, m4_patsubst_do): Extracted from
3893 previous builtins `regexp' and `patsubst'.
3894 (regexp, patsubst): Use them.
3895 (eregexp, epatsubst): New builtins.
3896 * doc/m4.texinfo (Patsubst, Regexp): Rename and complete as...
3897 (Epatsubst and Patsubst, Eregexp and Regexp): these.
3898 (Extensions): More info on REs.
3900 2001-10-04 Akim Demaille <akim@epita.fr>
3902 * modules/modtest.c (init_handler): Consistently output to stderr.
3903 (finish_handler): New.
3904 (test): The `if' is an `assert'.
3905 * tests/modules.at: Adjust.
3907 2001-10-04 Akim Demaille <akim@epita.fr>
3909 * m4/utility.c (m4_bad_argc): Detail the mismatches.
3911 2001-10-01 Akim Demaille <akim@epita.fr>
3913 * tests/generate.awk: Tag the tests with `documentation'.
3914 * tests/modules.at (AT_CHECK_M4_MODTEST): New.
3915 Use the make the existing modtest tests more uniform, and complete
3916 the set of possibilities.
3918 2001-10-01 Akim Demaille <akim@epita.fr>
3920 * config/gmp.m4: Consult the user before using GMP: use
3922 * configure.ac: Adjust.
3923 * modules/gmp.c: No protection needed as the module is not built
3926 2001-10-01 Akim Demaille <akim@epita.fr>
3928 * tests/generate.awk: Remove debugging code.
3929 (fatal): Specify the current location.
3931 * m4/debug.c, m4/macro.c, m4/utility.c, modules/format.c,
3932 * modules/gnu.c, modules/m4.c: Use M4ARG.
3934 2001-10-01 Akim Demaille <akim@epita.fr>
3936 * modules/gnu.c (RE_SYNTAX_BRE, RE_SYNTAX_ERE): New.
3937 (m4_regexp_compile): New.
3938 (regexp, patsubst): Use it.
3940 2001-09-30 Gary V. Vaughan <gary@gnu.org>
3942 Reinstate the memory handling improvements from the patch I just
3943 reverted. Relevant ChangeLog entries repeated here:
3945 * m4/module.c (m4_module_remove): New function that holds the core
3946 of the old m4_module_unload.
3947 (m4_module_unload): Use it.
3948 (m4_module_unload_all): When we know the modules will never be
3949 used again (i.e. on exit), free up as much module memory as
3950 possible. There are still some artifacts from resident modules
3951 living inside ltdl.c, but everything else is freed.
3952 * m4/debug.c (m4_debug_exit): Free memory allocated in
3954 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
3955 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
3956 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
3957 * m4/m4module.h: Updated prototypes.
3958 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
3959 * m4/hash.h: Updated prototypes.
3960 * src/main.c (main): Use all these new functions to clean up as
3961 much memory as possible before exit.
3963 2001-09-30 Gary V. Vaughan <gary@gnu.org>
3965 Reverted my large patch for removing the old m4_symbol
3966 structure on 2001-09-20. We are still not happy about the way
3967 trace works in conjunction with defn and undefine, and leaving
3968 the reverted patch active prevents us from moving the traced
3969 bit from the definition back to the symbol.
3971 2001-09-30 Gary V. Vaughan <gary@gnu.org>
3973 * configure.in: Moved to...
3974 * configure.ac: ...here. Added a libtool like timestamped
3975 banner, and tidied up the libltdl cruft.
3976 * config/mkstamp: Script to extract a timestamp from ChangeLog.
3977 * modules/Makefile.am (INCLTDL): Removed. This is required
3978 only when libltdl is configured in a subdirectory.
3979 * src/Makefile.am: Ditto.
3980 (LIBADD_DL): No need to add this again, libtool already knows
3981 that libm4.la depends on it.
3982 * m4/Makefile.am: Automake sets variables from AC_SUBST. Use
3985 * TODO: stackovf.c is basically broken.
3986 Reported by Marc Espie <espie@schutzenberger.liafa.jussieu.fr>
3988 2001-09-28 Akim Demaille <akim@epita.fr>
3990 * tests/Makefile.am (EXTRA_DIST): `m4' is not to be shipped.
3992 2001-09-27 Akim Demaille <akim@epita.fr>
3994 * tests/m4.in: Don't use short options.
3995 Simplify the stderr signature normalization.
3997 2001-09-27 Akim Demaille <akim@epita.fr>
3999 tests/m4 shall be position independent.
4003 * tests/testsuite.at: No args to AT_INIT.
4004 * configure.in, tests/Makefile.am: Adjust.
4006 2001-09-22 Akim Demaille <akim@epita.fr>
4008 Autotest has changed again.
4010 * tests/Makefile.am (DISTCLEANFILES): Add package.m4.
4011 (package.m4): Remove.
4012 * configure.in: Adjust to LIBADD_GMP.
4014 2001-09-21 Gary V. Vaughan <gary@gnu.org>
4016 * config/gmp.m4 (AC_ARG_WITH): Removed.
4017 (GMP_LIB): Renamed to LIBADD_GMP for consistency.
4018 (AC_LIB_GMP): When performing a test compile against libgmp,
4019 include the header gmp.h if possible, and link against -lgmp. If
4020 they both work define USE_GMP.
4021 * modules/Makefile.am (mpeval_la_LIBADD): Add LIBADD_GMP.
4022 (mpeval_LTX_init_func): Complain on load that there was no libgmp
4025 2001-09-20 Gary V. Vaughan <gary@gnu.org>
4027 * m4/evalparse.c: Moved to...
4028 * modules/evalparse.c: ...here. This code is shared between
4029 modules/mpeval.c and modules/m4.c, so there is no need to pollute
4030 the libm4 API with its details. Moderately rewritten to interface
4031 into its clients more simply.
4032 * m4/eval.c: Deleted. Migrated functionality to...
4033 * modules/m4.c: ...here.
4034 (builtin_eval): Implemented in terms of the new interface style.
4035 * modules/mpeval.c (builtin_mpeval): Ditto.
4036 * m4/m4module.h: Removed references to the former m4/eval.c.
4037 * m4/Makefile.am (libm4_la_SOURCES): Removed eval.c.
4038 (EXTRA_libm4_la_SOURCES): Deleted.
4039 * modules/Makefile.am (EXTRA_m4_la_SOURCES): Reference evalparse.c.
4040 (EXTRA_mpeval_la_SOURCES): Reference evalparse.c.
4042 2001-09-20 Akim Demaille <akim@epita.fr>
4044 * config/gmp.m4 (AM_WITH_GMP): Rename as...
4046 By default, use gmp.
4048 * configure.in: Adjust.
4049 Use Automake conditionals for USE_GMP.
4050 Always compute sizeof (long long int).
4051 This was a bug BTW, as `eval' (not `mpeval') depends on it:
4052 before, it was used _only_ if mpeval was not activated.
4053 * modules/Makefile.am (pkglibexec2dir, +pkglibexec2_LTLIBRARIES)
4054 (mpeval_la_LIBADD): New macros.
4055 * modules/mpeval.c: No longer be conditioned by WITH_GMP.
4057 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Create package.m4.
4058 * tests/atlocal.in, tests/builtins.at: Depend upon USE_GMP, not
4061 2001-09-20 Akim Demaille <akim@epita.fr>
4063 * tests/Makefile.am (package.m4): New.
4064 * tests/testsuite.at: Adjust AT_INIT and AT_VICTIMS.
4066 2001-09-20 Gary V. Vaughan <gary@gnu.org>
4068 More cleanup. After the last patch, m4_symbol holds nothing but
4069 the head of a chain of m4_token_data. So I have removed the old
4070 m4_symbol, so that m4_token_data chains are stored directly in the
4071 value cell of a hash table node. But there's more... m4_symbol
4072 was a more natural name for the symbol value cell, and now that it
4073 is gone I have renamed the former m4_token_data structure to
4074 m4_symbol. This change turned out to be a pig to get right, since
4075 the original code didn't need to modify the value cell itself,
4076 since changing the chain happened inside the m4_symbol that used
4077 to be returned -- I had to pass the address of the value cell
4078 across various function calls, incase the head value changed. I
4079 also tightened up the memory management to help me find a nasty
4080 memory corruption bug that took me all night to track down...
4082 * m4/m4private.h (struct m4_symbol): Removed.
4083 (struct m4_token_data): Renamed to `struct m4_symbol'. Updated
4085 * m4/hash.c (m4_hash_iterator_value): Return the address of the
4086 value cell. Updated all callers.
4087 * m4/symtab.c: Took advantage of the simplification in the data
4088 structures to rewrite a lot of this file more simply. There is
4089 still some room for optimisation here, but we should tackle that
4090 systematically closer to the release.
4092 * m4/ltdl.c: Added dmalloc support, and fixed some memory leaks it
4093 revealed. This version is ahead of CVS libtool until I get chance
4094 to flush my changes.
4095 * m4/module.c (m4_module_remove): New function that holds the core
4096 of the old m4_module_unload.
4097 (m4_module_unload): Use it.
4098 (m4_module_unload_all): When we know the modules will never be
4099 used again (i.e. on exit), free up as much module memory as
4100 possible. There are still some artifacts from resident modules
4101 living inside ltdl.c, but everything else is freed.
4102 * m4/debug.c (m4_debug_exit): Free memory allocated in
4104 * m4/input.c (m4_input_exit): Ditto wrt m4_input_init().
4105 * m4/output.c (m4_output_exit): Ditto wrt m4_output_init ().
4106 * src/stackovf.c (stackovf_exit): Ditto wrt setup_stackovf_trap ().
4107 * m4/m4module.h: Updated prototypes.
4108 * m4/hash.c (m4_hash_exit): Free the nodes on the free list.
4109 * m4/hash.h: Updated prototypes.
4110 * src/main.c (main): Use all these new functions to clean up as
4111 much memory as possible before exit.
4113 2001-09-18 Gary V. Vaughan <gary@gnu.org>
4115 The `traced' flag needs to be attached to the definition of a
4116 symbol rather than the current symbol containing the definition.
4117 Implementing this showed up some long standing post 1.4 bugs in
4118 flag propogation which I also fixed.
4120 * m4/m4private.h (struct m4_symbol): Remove the traced flag.
4121 (struct m4_token_data): And add it back in here.
4122 * m4/input.c (init_macro_token): Propogate the traced flag
4124 * m4/macro.c (expand_argument): Ditto.
4125 * tests/builtins.at (trace2, trace3): New tests based on Akim's
4128 2001-09-08 Gary V. Vaughan <gary@gnu.org>
4130 * m4/m4private.h (struct m4_token_data): Simplified by removing
4131 the redundant `traced' flag, and one level of structure nesting.
4132 (M4_TOKEN_DATA_FUNC_TRACED): Removed.
4133 * m4/input.c (init_macro_token): No need to initialise removed
4135 * m4/macro.c (expand_argument): No need to copy it either.
4136 * m4/utility.c (m4_token_data_func_traced): Or provide an access
4139 * m4/hash.c (m4_hash_bucket_insert): Symbol shadowing is no longer
4140 dependant on multiple symbols with the same key, so preserving
4141 relative symbol order in each bucket during resizing is no longer
4142 required. The resize function is considerably faster as a result.
4144 * m4/m4module.h, m4/builtin.c, m4/symtab.c:
4145 s/m4_symbol_insert/m4_symbol_define/g;
4146 s/m4_builtin_insert/m4_builtin_define/g;
4147 s/m4_macro_insert/m4_macro_define/g. Updated all callers.
4149 2001-09-08 Gary V. Vaughan <gary@gnu.org>
4151 Get rid of m4_symbol_lookup_t entirely. With Akim's earlier
4152 commits, the m4_lookup_symbol dispatch function is split into
4153 specialised functions that must be called directly.
4155 * m4/m4module.h (m4_symbol_lookup_t): Removed.
4156 * m4/symtab.c (m4_lookup_symbol): Removed.
4157 (m4_symbol_builtin, m4_symbol_macro): New functions.
4158 * m4/builtin.c (m4_builtin_define): Split into...
4159 (m4_builtin_pushdef, m4_builtin_insert): ...these.
4160 (m4_macro_define): Split into...
4161 (m4_macro_pushdef, m4_macro_insert): ...these.
4162 * src/main.c (main): Set command line macros from `-D' parameters
4163 using `m4_macro_define'.
4165 2001-09-08 Gary V. Vaughan <gary@gnu.org>
4167 * m4/symtab.c (m4_symtab_remove_module_references): Renamed as
4168 this from m4_remove_table_reference_symbols().
4169 * m4/m4module.h, m4/module.c: Updated all references.
4171 2001-09-07 Akim Demaille <akim@epita.fr>
4173 * modules/stdlib.c, modules/times.c: Misc cleanups.
4175 2001-09-07 Akim Demaille <akim@epita.fr>
4177 * configure.in: We now need Autoconf 2.52e.
4178 * m4/m4module.h (m4_symbol_lookup_t): Remove `M4_SYMBOL_POPDEF'
4179 and `M4_SYMBOL_DELETE'.
4180 * m4/symtab.c (m4_lookup_symbol, symtab_debug): Adjust.
4181 * src/main.c (main): Adjust.
4183 2001-09-06 Gary V. Vaughan <gary@gnu.org>
4185 Fix the obstack.h problem once and for all! At configure time we
4186 can test for a system supplied obstack.h: depending on the
4187 result, we now generate system.h with an #include of the correct
4188 header. As a bonus, I've also added a --with-included-obstack,
4189 incase the user doesn't like the system obstack for some
4190 reason... and also we can test the shipped obstack on a system
4191 that has oe of its own. We also now need to be careful to add
4192 build directories to the include search path, since the generated
4193 system.h will be in the build tree.
4195 * configure.in (AC_CONFIG_FILES): Generate system.h from
4197 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Determine whether to
4198 include the system obstack header or the copy shipped with M4.
4199 Allow the user to override configure and force the build to use
4200 the shipped version.
4201 * m4/system-h.in: New file, template for...
4202 * m4/system.h: ...this. Now deleted.
4203 * m4/m4module.h: Include system.h before everything else.
4204 * src/freeze.c: Ditto.
4205 * m4/Makefile.am (dist-hook): Remove generated system.h.
4206 (INCLUDES): Check builddir for generated headers before checking
4208 * modules/Makefile.am (INCLUDES): Ditto.
4209 * src/Makefile.am (INCLUDES): Ditto.
4211 2001-09-05 Gary V. Vaughan <gary@gnu.org>
4213 * TODO: Remove the items that have been addressed already.
4215 2001-09-05 Akim Demaille <akim@epita.fr>
4217 * src/main.c (main): Standardize --version.
4219 2001-09-05 Akim Demaille <akim@epita.fr>
4221 * modules/format.c (format): Have a bigger `str'.
4223 2001-09-05 Akim Demaille <akim@epita.fr>
4225 Rationalize warnings, reporting the macro name as if it were a
4226 program name, and assertions.
4228 * m4/m4module.h (m4_lookup_symbol): Prototype, it is still used.
4230 * m4/symtab.c (m4_lookup_symbol, m4_symbol_popdef)
4232 Use assert for internal errors.
4233 * m4/utility.c (m4_bad_argc, m4_numeric_arg, m4_dump_symbols): Use
4235 * modules/m4.c (undefine, defn, traceon, traceoff, dumpdef): use
4237 * tests/builtins.at (pushpop): Adjust.
4239 2001-09-05 Akim Demaille <akim@epita.fr>
4241 * m4/symtab.c (m4_symbol_insert): Don't use `foo () || bar ()'
4244 2001-09-05 Akim Demaille <akim@epita.fr>
4246 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_LOOKUP.
4247 * m4/macro.c, m4/symtab.c: Adjust.
4249 2001-09-05 Akim Demaille <akim@epita.fr>
4251 * m4/symtab.c (m4_symbol_popdef, m4_symbol_delete): Rename as...
4252 (m4_symbol_pop, m4_symbol_del): this.
4253 (m4_symbol_lookup, m4_symbol_pushdef, m4_symbol_insert)
4254 (m4_symbol_popdef, m4_symbol_delete): New.
4255 (m4_lookup_symbol): Adjust.
4256 * m4/m4module.h, src/main.c, modules/gnu.c, modules/m4.c: Adjust.
4258 2001-09-05 Akim Demaille <akim@epita.fr>
4260 * m4/m4module.h (m4_symbol_lookup): Rename as...
4261 (m4_symbol_lookup_t): this.
4263 2001-09-05 Akim Demaille <akim@epita.fr>
4265 * m4/m4module.h (m4_symbol_lookup): Remove M4_SYMBOL_IGNORE,
4267 * m4/symtab.c (m4_lookup_symbol): Adjust.
4269 2001-09-03 Gary V. Vaughan <gary@gnu.org>
4271 Bootstrap will now work with Libtool 1.4.1 or higher:
4272 * bootstrap: Remove stale autom4te.cache files when
4274 * config/Makefile.am (ACLOCAL_MACROS): Add ltdl.m4 and
4276 * bootstrap: Ignore acinclude.m4 now the we include ltdl.m4 and
4277 libtool.m4 directly.
4278 Run libtoolize to refresh ltmain.sh.
4279 * config/ltmain.sh: Deleted.
4280 * acinclude.m4: Deleted.
4281 * m4/ltdl.c, m4/ltdl.h: Updated from libtool-1.4.1.
4283 * config/debug.m4 (AC_LIBTOOL_COMPILER_OPTION): Provide a fallback
4284 implementation for the cvs impaired libtool user.
4286 2001-09-03 Akim Demaille <akim@epita.fr>
4288 * m4/symtab.c (m4_lookup_symbol): Give more details when reporting
4290 Avoid using `default' in switch, as it hides useful compiler
4291 warnings when a case is forgotten.
4293 2001-09-03 Akim Demaille <akim@epita.fr>
4295 * src/main.c (MODULE_SHORTOPT, MODULEPATH_SHORTOPT): Remove, there
4296 is no such thing as `WITH_MODULES'.
4298 2001-09-03 Akim Demaille <akim@epita.fr>
4300 Improve the test suite's selfcontainedness.
4302 * doc/m4.texinfo: Let `input.m4' be the input file, not `in'.
4303 (Include, Undivert): Tag the other input files.
4304 * tests/generate.awk: Catch `@comment file:'.
4305 `-I $src' is no longer needed.
4306 `next' is really like `return': the rest is skipped.
4307 Adjust to `input.m4'.
4308 (fatal): New function.
4309 * tests/foo, tests/incl.m4: Remove.
4311 2001-09-01 Gary V. Vaughan <gary@gnu.org>
4313 The shadowing mechanism and, infact, the whole symbol table
4314 implementation was creaking under the weight of the features piled
4315 on top of it. We now have a separate hash table module which will
4316 dynamically resize to keep symbol density withing good performace
4317 limits, and a new symtab module layered above it. Symbol lookups
4318 are now marginally more efficient (since the shadowed flag is no
4319 longer required) and symbol removal, such as on module unload, is
4320 considerably faster due to a reorganisation of the data structures
4323 * src/main.c (main): Don't mention `-H'.
4324 * doc/m4.texinfo (Invoking m4): Document that -H no longer has any
4327 * m4/hash.c: New generalised dynamic hash table data structure
4329 * m4/hash.h: Public interface.
4330 * m4/Makefile.am (pkginc_HEADERS): Add hash.h.
4331 (libm4_la_SOURCES): Add hash.c.
4332 * m4/symtab.c: More or less rewritten from scratch, within the
4333 bounds of the previous API.
4334 (m4_symtab_apply): A cleaner version of the old hack_all_symbols
4335 call. Updated all callers.
4336 * m4/m4module.c: #include <m4/hash.h>, and changed all affected
4337 declarations to reflect API changes.
4338 (M4INIT): Generate a declaration too, to avoid the warning with
4339 --enable-debug builds.
4342 * m4/utility.c (hash_table_size): Removed.
4343 (m4_dump_symbols): Rewritten to build and qsort an array of symbol
4344 names, which are then looked up by builtin_dumpdef() as necessary.
4345 This implies a small speedup in builtin_symbols(), which discarded
4346 all of the symbol info under the old call.
4347 * m4/m4private.h (m4_symbol): Removed shadowed flag -- symbol
4348 shadowing is implicit in respect to the new data structures.
4349 symbol names are no longer duplicated here, they are stored in the
4350 key field of the hash table.
4351 Moved macro_args and blind_no_args...
4352 (m4_token_data): ...to here.
4353 m4/macro.c (expand_macro): Added a name argument since the symbol
4354 name is no longer copied into each struct m4_symbol. Modified all
4356 (collect_arguments): Ditto.
4357 * modules/m4.c (set_trace): Ditto.
4358 * modules/gnu.c (builtin_symbols): Updated.
4359 * src/freeze.c (produce_symbol_dump): Much improved in light of
4360 the improved symbol table layout.
4362 2001-09-01 Gary V. Vaughan <gary@gnu.org>
4364 * m4/m4private.h (SYMBOL_NEXT): Move into m4's name space; renamed
4366 (SYMBOL_TRACED): Similarly renamed by prefixing with `M4_'.
4367 (SYMBOL_SHADOWED, SYMBOL_MACRO_ARGS, SYMBOL_BLIND_NO_ARGS,
4368 SYMBOL_NAME, SYMBOL_TYPE, SYMBOL_TEXT, SYMBOL_FUNC,
4369 SYMBOL_HANDLE): Ditto.
4370 * m4/builtin.c, m4/macro.c, m4/symtab.c, m4/utility.c,
4371 modules/gnu.c, modules/m4.c, src/freeze.c,
4372 src/main.c: Updated all references.
4374 * src/Makefile.am (m4_SOURCES): Don't list $(M4OBJS) here, since
4375 Automake 1.5 chokes on dynamic source file lists, Besides, it is
4376 already listed in m4_LDADD... how did that ever used to work?
4377 * configure.in (getopt.h): Use AC_CONFIG_LINKS instead of a manual
4379 * config/gnu-obstack.m4 (M4_AC_FUNC_OBSTACK): Ditto.
4380 Suggested by Tim Van Holder <tim.van.holder@pandora.be>
4382 * tests/m4: Don't call the m4 wrapper script with libtool, it
4383 works fine all by itself.
4385 2001-08-30 Gary V. Vaughan <gary@gnu.org>
4387 The experimental `changeword' feature never took off, and has
4388 no obvious advantages over `changesyntax' to compensate the
4389 enormous speed penalty it carries:
4390 * configure.in (ENABLE_CHANGEWORD): Removed.
4391 * m4/m4module.h (m4_set_word_regexp): Removed.
4392 * m4/m4private.h (m4_token_data): Removed original_text field.
4393 * m4/utility.c (m4_token_data_orig_text): Removed.
4394 * m4/input,c: Removed all conditional ENABLE_CHANGEWORD code.
4395 * m4/macro.c: Ditto.
4396 * src/main.c: Ditto.
4397 * modules/Makefile.am (changeword.la): Removed.
4398 * modules/changeword.c: File removed.
4399 * doc/m4.texinfo: References to changeword and --word-regexp
4401 * po/POTFILES.in: modules/changeword.c removed.
4402 * tests/atlocal.in (ENABLE_CHANGEWORD): Removed.
4403 * tests/builtins.at (changeword): Test removed.
4405 2001-08-30 Akim Demaille <akim@epita.fr>
4407 * bootstrap.sh: Create aclocal.m4 instead of modifying it.
4408 This also help having a single list of m4 files: in
4410 * config/Makefile.am (STANDARD_MACROS): Rename as...
4411 (ACLOCAL_MACROS): this.
4412 (list-standard-macros): Remove.
4415 2001-08-29 Gary V. Vaughan <gary@gnu.org>
4417 In an attempt to moderate my egomania...
4418 * tests/modules.at: Remove attributions.
4420 * tests/generate.awk: When making substitutions to "@&t@", either
4421 "&" or "\&" in the substitution string argument to gsub refer back
4422 to the matched text. "@\\&t@" seems to work though, Tests 43 and
4425 2001-08-29 Akim Demaille <akim@epita.fr>
4427 * tests/others.at (changeword, ddivert, debug, esyscmd, exp, gmp)
4428 (include, indir, multiquotes, patsubst, pushdef/popdef, regexp)
4429 (sync-lines, trace, translit, undivert, wrap): Move to...
4430 * tests/builtins.at: this new file.
4431 * tests/others.at (Discard comments, import-environment): Move to...
4432 * tests/options.at: this new file.
4434 2001-08-29 Akim Demaille <akim@epita.fr>
4436 * tests/others.at (Freezing modules)
4437 (--module-directory: absolute path, modpath2, modpath3)
4438 (M4MODPATH: absolute path, modtest, shadow, unload): Move to...
4439 * tests/modules.at: here, new file.
4440 * tests/others.at, tests/generate.awk: Add a banner.
4441 * tests/testsuite.at: Adjust.
4442 (AT_CHECK_M4_FILTER): New, but unused.
4444 2001-08-29 Akim Demaille <akim@epita.fr>
4446 * tests/testsuite.at (AT_CHECK_M4): Don't pass -I, let the tests
4448 * tests/others.at (wrap): Inline wrap.m4.
4449 (shadow): Inline shadow.m4.
4450 (iso8859): Don't specify the path from top_srcdir, but from srcdir.
4451 * tests/m4: Simplify.
4453 2001-08-29 Akim Demaille <akim@epita.fr>
4455 * tests/Makefile.am ($(srcdir)/$(TESTSUITE)): Use autom4te's
4458 2001-08-29 Akim Demaille <akim@epita.fr>
4460 * tests/generate.awk (normalize): s/@__@/@&t@/.
4462 2001-08-28 Akim Demaille <akim@epita.fr>
4464 * examples/indir.m4, tests/others.at (indir): s/nonsens/nonsense/.
4466 2001-08-28 Gary V. Vaughan <gary@gnu.org>
4468 * bootstrap (generate.awk): Generate test cases with new script.
4470 2001-08-27 Akim Demaille <akim@epita.fr>
4472 * tests/Makefile.am (installcheck-local): Don't use
4473 `dc_install_base' which is not visible here, but `exec_prefix'
4474 which is clearly the RT anyway.
4475 * tests/testsuite.at (AT_CHECK_M4): Don't pass -M here since it is
4476 related to testing a now installed m4.
4477 * tests/m4: Do it here.
4479 2001-08-27 Akim Demaille <akim@epita.fr>
4481 * tests/others.at (indir): Formatting change.
4483 2001-08-27 Akim Demaille <akim@epita.fr>
4485 * tests/Makefile.am (installcheck-local): New.
4486 * tests/testsuite.at (AT_CHECK_M4): Pass `-b' so that C-c works on
4488 Prefer options over envvars.
4489 * src/main.c (main): First bug caught by the test suite (yeah!):
4490 --batch lacked a `break' which resulted in an accidental
4491 invocation of --discard-comments.
4493 2001-08-27 Akim Demaille <akim@epita.fr>
4495 * tests/others.at (capitalize, changeword, comments, ddivert)
4496 (debug, esyscmd, exp, foreach, forloop, fstab, hanoi, include)
4497 (misc, multiquotes, patsubst, pushdef/popdef, regexp, reverse)
4498 (sysv-args, trace, translit, undivert): Don't rely on files in
4499 examples/: AT_DATA them.
4501 2001-08-27 Akim Demaille <akim@epita.fr>
4503 Let the test suite use a wrapper around the not installed m4 to
4504 pretend it is (installed).
4506 * bootstrap (aclocal.m4): Output AC_SUBST's and AM_CONDITIONAL's in
4507 such a way that m4 does not process them.
4508 * configure.in: The package name seems to be `m4', not `M4'.
4510 * tests/atlocal.in (at_package, M4): Remove.
4511 * tests/testsuite.at, tests/others.at: Use m4, not $M4.
4513 2001-08-27 Akim Demaille <akim@epita.fr>
4515 * tests/Makefile.am (CLEANFILES): Remove.
4516 (DISTCLEANFILES, clean-local): New.
4517 * examples/mktests.sh: Remove.
4519 2001-08-27 Akim Demaille <akim@epita.fr>
4521 * Makefile.am (AUTOMAKE_OPTIONS): 1.5.
4522 Don't use aclocal: it's written by hand.
4523 * aclocal.m4: m4_include all the files instead of being built by
4525 * bootstrap: Help automake find the AC_SUBSTs and AM_CONDITIONALs
4526 until it reads the traces by itself.
4527 * configure.in: Require Autoconf 2.42c as we are now using
4528 AC_CONFIG_TESTDIR instead of AT_CONFIG.
4529 Catch unexpanded `jm_' macros.
4530 * config/atconfig.m4: Remove.
4531 * config/error.m4: new.
4532 * config/Makefile.am: Ship the files included by aclocal.m4.
4533 * tests/Makefile.am (TESTSUITE_SOURCES): Rename as...
4534 (TESTSUITE_AT): this, to please Automake.
4535 (TESTSUITE): This target uses autotest/autotest.m4, not
4536 autotest/general.m4.
4537 * tests/testsuite.at: Prereq Autotest 2.52c.
4538 * examples/Makefile.am (pkgdata_DATA): Rename as...

4540 * doc/Makefile.am (man_MANS): Rename as...
4541 (dist_man_mans): this.
4543 2001-08-20 Gary V. Vaughan <gary@gnu.org>
4545 * m4/system.h [cygwin*]: Thanks to Paul Sokolovsky and
4546 Robert Collins, building on Cygwin no longer requires Windows
4547 import and export symbol decorations.
4548 * m4/m4module.h (M4_SCOPE) [cygwin*]: Deleted all occurences.
4549 * m4/error.h (M4_SCOPE) [cygwin*]: Ditto.

4564 Ansify the source. Previously we had a mix, where my code was
4565 in a K&R compatible style, and the preexisting code was in ANSI
4566 style. Nothing is lost wrt release 1.4 by reverting to ANSI,
4567 and now the code base is much cleaner.

4610 * m4/utility.c (m4_numeric_arg): Spell out the culprit.
4611 * modules/m4.c (undivert): Disable the possibility of undiverting
4612 several files at once: it is not documented, it is inconsistent
4613 with the other macros, it can be straightforwardly mocked by
4614 several invocations, and most importantly, it prevents the
4615 possibility of other kinds of extension.
4616 Use `m4_numeric_arg'.
4618 2001-08-20 Akim Demaille <akim@epita.fr>
4620 * examples/include.m4: Typo.
4621 * tests/generate.awk: Really add it.

4626 2001-08-20 Akim Demaille <akim@epita.fr>
4628 Use sprintf, not ecft and friends since it is standard, portable,
4629 simplifies the code, and since the latter is even deprecated

4778 Drop Autoconf 2.13 compatibility.
4780 * configure.in (changeword): No need to undefine it, as anyway if
4781 it's defined, M4sugar moved it as m4_changeword.

4839 (M4FINISH_HANDLER): And similarly for finish functions.
4840 * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER
4841 -- Add indirection to the CONC macro so that arguments are
4843 * modules/modtest.c (m4_init_module): Replaced with M4INIT_HANDLER.
4844 * modules/shadow.c (m4_init_module): Ditto.

4856 instead of the old module argument.
4857 (m4_builtin_table_install): Ditto.
4858 * modules/load.c (m4_resident_module): Removed. This is no
4859 longer implemented as a magic symbol...

4879 module association does not belong with the symbol...
4880 * m4/input.c (struct m4_builtin): ...it belongs with the builtin

4899 (CDPATH) Neutralize.
4900 * tests/gethem: Use them.
4902 2001-08-14 Gary V. Vaughan <gary@gnu.org>

4919 shell variable m4_cv_func_obstack_h.

4921 script and m4 binary by using $srcdir.

4924 optargs to the existing libltdl search path.
4925 * acinclude.m4: Regenerate from latest libtool,m4 and ltdl.m4.
4926 * m4/ltdl.c: Updated.

4932 * src/main.c (main): Add `-b' (for `batch') mode switch to force
4933 interactive mode off.

4937 * configure.in: Require Autoconf 2.52.
4938 (AC_ARG_PROGRAM): Remove, handled by Automake.

4944 (M4_AC_FUNC_OBSTACK): Rename `m4_obstack' and `m4_obstack_h'.

5002 feature to mark modules as resident if they export
5003 `m4_resident_module' as TRUE.
5004 (m4_module_unload): Do not remove resident modules, and take care
5005 with symbol insertion and deletion with resident modules.

5070 Move the implementation of GMP support for the mpeval() builtin
5071 into a loadable module that depends on libgmp. mpeval() and
5072 eval() share a common parser, now in m4/evalparser.c; the code
5073 in m4/numb.c and m4/numb.h is now physically split between
5074 m4/eval.c (the eval() backend) and modules/mpeval.c (the
5075 mpeval() backend), rather than being differentiated by cpp
5076 macros and multiple inclusion. The mpeval module is always
5077 built but will generate an diagnostic if it is used from an
5078 installation that didn't link in the gmp library.
5079 * modules/Makefile.am: build and install the new mpeval module.
5080 * modules/mpeval.c: Now contains the former parts of m4/numb.c
5081 and m4/numb.h that are required for gmp support in mpeval().
5082 * m4/Makefile.am (libm4_la_SOURCES): Removed evalmp.c.
5083 * m4/evalmp.c: Removed.
5084 * m4/m4module.h: Removed conditional prototype for
5086 * m4/eval.c: Rewritten. Contains the former parts of m4/numb.c
5087 and m4/numb.h that do not rely on gmp.
5088 * m4/evalparse.c: New file, contains the shared parts of the
5089 eval() and evalmp() parser implementations, and is no longer
5090 unencumbered by cpp magic to uncover the right parts.
5091 * m4/numb.h: Removed. It's former contents are split between
5092 m4/eval.c and modules/mpeval.c.
5095 * tests/other-tests/changeword.test: New test. Rudimentary
5096 testing of changeword builtin runs only if --wnable-changeword
5097 was used at configure time.
5098 * tests/mkconfig.sh: Solaris sed (at least) does not parse nested
5099 alternation correctly. Split into two expressions to compensate.
5100 * m4/input.c (m4_input_init): Use m4_ prefix on m4_set_word_regexp.
5101 * modules/Makefile.am: Build changeword module.
5102 * modules/changeword.c (m4_macro_table): Define __m4_changeword__
5103 only when --enable-changeword was passed to configure.
5104 (builtin_changeword): If --enable-changeword was not used, then
5105 report that changeword() builtin has no support in m4 binary.
5107 2000-11-28 Gary V. Vaughan <gary@gnu.org>
5109 * src/main.c (main): Fixed a particularly nasty bug is
5110 user_search_path setting -- the -M flag processing must be
5111 extremely careful with search path ordering, or else the default
5112 installed module directory (possibly containing modules from a
5113 previous release) is placed earlier in the search path than any -M
5114 arguments (which are relied upon to load uninstalled modules with
5115 most of the tests in the regresion suite).
5117 * modules/load.c (builtin_load): Nasty hack to prevent adding
5118 symbols to symtab again if a module is loaded more than once.
5119 * modules/m4.c (builtin_ifelse): removed unused variable argv0.
5121 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed a
5122 possible NULL pointer dereference.
5124 * m4/module.c (m4_module_find_by_modname): Renamed from
5125 m4_module_modname_find. Fixed all references.
5126 (m4_module_find_by_builtin): New function.
5128 * modules/modfreeze.test: load the `load' module with each
5130 * src/freeze.c (produce_frozen_state): Simplified in light of
5131 module field in m4_symbol. Allow a third argument for text macros
5132 to name the originating module.
5133 (reload_frozen_state): ditto.
5134 * m4/m4module.h: Fixup prototypes.
5135 * m4/builtin.h (m4_builtin_define): Add a module argument so
5136 that symbols can be registered against the defining module.
5137 (m4_macro_define): ditto.
5138 * m4/m4private.h (m4_symbol): Make the module field const to save
5139 on casting in the rest of the code.
5140 (SYMBOL_MODULE): New macro.
5142 * m4/symtab.c (m4_remove_table_reference_symbols): Fixed stupid
5143 symbol reference maintenance bugs when removing a symbol from the
5146 * src/stackovf.c (setup_stackovf_trap): Fixed some memory leaks.
5148 2000-11-27 Gary V. Vaughan <gary@gnu.org>
5150 * configure.in (m4_cv_func_obstack): A better check for whether
5151 libc has an obstack implementation.
5152 * m4/Makefile.am (EXTRA_libm4_la_SOURCES): add gnu-obstack.h.
5154 * configure.in (--with-modules): Changed semantics. This
5155 option is now used to list modules to be preopened.
5156 * src/m4.h: #include "ltdl.h" unconditionally.
5157 * src/main.c: Removed all dependencies on WITH_MODULES.
5158 * src/freeze.c: ditto.
5159 * modules/Makefile.am: ditto.
5160 * m4/m4.c (builtin_m4exit): ditto.
5161 * modules/modpath1.test: ditto.
5162 * modules/modpath2.test: ditto.
5163 * modules/modpath3.test: ditto.
5164 * modules/modpath4.test: ditto.
5165 * modules/modtest.test: ditto.
5166 * modules/shadow.test: ditto.
5167 * modules/unload.test: ditto.
5169 * m4/Makefile.am (libm4_la_SOURCES): Removed obstack.c, since it
5170 comes up on demand in LTLIBOBJS now.
5171 * configure.in (getopt_long): Creating and relying on a link for
5172 getopt.h on hosts with no getopt_long() of thier own works
5173 correctly now. This is necessary so that callers of getopt_long()
5174 can simply `#include <getopt.h>': the naive way of doing this
5175 would end up using our own getopt.h and the installed
5176 getopt_long(), which is asking for trouble!
5177 (obstack_init): A similar argument applies to obstack.h and
5180 * m4/ltdl.c: Upgraded to latest bleeding edge version again.
5181 On Solaris-2.5 (at least) the native dlopen implementation
5182 gets confused about m4.o when looking for module "m4". This
5183 version always looks for .la an .$lib_ext suffixed names first
5184 to work around the problem. Sigh.
5186 * po/POTFILES.in: Take account of these file movements.
5187 * src/Makefile.am (m4_SOURCES): removed eval.c.
5188 (EXTRA_m4_SOURCES): removed numb.c and numb.h.
5189 * m4/Makefile.am (libm4_la_SOURCES): added eval.c.
5190 (EXTRA_libm4_la_SOURCES): added numb.c and numb.h.
5191 * modules/m4.c (builtin_eval): Use m4_evaluate().
5192 * m4/eval.c: Moved here from src/eval.c to facilitate
5193 implementation of eval() builtin as part of the `m4' loadable
5195 (m4_evaluate): renamed from evaluate for namespace cleanliness.
5196 * m4/numb.c: Moved here from src/numb.c, since it is #included
5197 into eval.c at compile time.
5198 * m4/m4module.h (m4_evaluate): Added prototype.
5199 * src/m4.h (evaluate): Removed prototype.
5201 2000-11-25 Gary V. Vaughan <gary@gnu.org>
5203 * modules/perl.c (builtin_perleval): Use PL_na for
5204 compatibility with perl-5.6.
5206 * src/main.c (main): It is now safe to
5207 ``m4_module_install("m4")'', without tripping over the m4
5209 * m4/ltdl.h, m4/ltdl.c: Upgraded to latest bleeding edge
5210 versions having fixed the insidious module search order bug.
5212 * m4/Makefile.am (libm4_la_LIBADD): New magic -- we are
5213 supposed to be using @LIBADD_DL@; @DLLDFLAGS@ is dead.
5215 * configure.in: Figure out whether to use the installed
5216 getopt.h or the supplied one.
5217 * src/Makefile.am: ditto.
5219 * po/POTFILES.in: List files in their new positions.
5221 * config/ltmain.sh: This needs to be checked in to match the
5222 libtool macros copied to acinclude.m4 (until a released
5223 libtool copes with m4's needs).
5224 * bootstrap: Run gettextize.
5226 2000-11-24 Gary V. Vaughan <gary@gnu.org>
5228 * AUTHORS: Added my details.
5231 * bootstrap: temporary update until released libtool catches up.
5233 * All files: Use new GNU GPL copyright blurb with current contact

5267 * modules/gnu.c: New file implementing a new loadable module wuth
5268 definitions for all the gnu extension builtins.
5269 * modules/format.c: Moved here from src/format.c. Now included
5272 * src/main.c (main): Load the traditional module if m4 was
5273 started in `no_gnu_extensions' mode.
5274 * modules/traditional.c: New file implementing the ``unix'' macro,
5275 required when m4 is executed in traditional mode, as a loadable
5278 * src/main.c: Renamed from m4.c to avoid confusion with
5280 (main): Always load the m4 module.

5293 * m4/symtab.c: ditto.
5294 * m4/debug.c: ditto.

5296 * m4/output.c: ditto.
5298 * m4/ltdl.h, m4/ltdl.c: ditto.
5299 * m4/utility.c: Odd functions moved here from files in the src
5300 directory to facilitate builtin migration.
5302 2000-08-12 Gary V. Vaughan <gary@gnu.org>
5304 * src/builtin.c (dump_symbols): Use "Undefined name `%s'" for
5305 error message, to make translators' jobs a little easier.
5306 (builtin_builtin): ditto.
5307 (builtin_traceon): ditto.
5308 (builtin_traceoff): ditto.
5309 Reported by Akim Demaille <akim@epita.fr>
5311 * m4/Makefile.am (pkgincdir): Deleted. Use automake's built in
5312 pkgincludedir instead.

5335 makeinfo calculates them for us, and to make any future
5336 reorganisation easier.
5337 (Frozen files): Document format version 2.
5338 `V' now takes argument `2'.
5339 `F' can take a single argument if symbol and builtin names
5340 are the same, or 3 arguments if the builtin is from a module.

5478 * src/m4.c (main): Assume interactive mode if STDIN is connected

5481 initialised from here when loading a frozen file.
5483 * src/builtin.c: Much improved macro definition style.
5484 * src/m4private.h: Internal structures for m4_builtin and

5498 table entries which refer to a given builtin table.

5551 * acm4/ltdl.m4: Updated to latest from libtool cvs.
5552 * acm4/modules.m4: Remove code which duplicates ltdl.m4 and
5553 increment serial number.
5555 * Makefile.am (SUBDIRS): Moved @MODULES_DIR@ to compile before
5556 src dir and immediately after libm4 is built for confidence that
5557 it doesn't rely on the src directory.
5558 (SUBDIRS): Moved doc dir to the end since helptoman.pl and
5559 makeinfo stop the build on cygwin (because they don't work).
5561 * src/m4.h: use GNU standard #if HAVE_CONFIG_H ideom.
5563 * m4/m4private.h: ...is not a public header, so moved to src.
5564 Add `#include <config.h>', `#define _COMPILING_M4' and
5566 * m4/Makefile.am (noinst_HEADERS): remove m4private.h.
5567 * src/Makefile.am (noinst_HEADERS): add m4private.h.
5568 * src/builtin.c: `#include "m4private.h"' now takes care of the
5569 above. Duplicates removed.
5570 * src/debug.c: ditto.
5571 * src/eval.c: ditto.
5572 * src/evalmp.c: ditto.

5587 (INCLUDES): Look first in $(top_srcdir) (for eg. <m4/error.h>),
5588 and then in $(top_srcdir)/lib (for eg. "m4private.h").
5589 * src/Makefile.am (m4_LDADD): replace libi/libm4.la with
5591 * m4/m4error.h: Renamed error.h, for installation to
5592 $prefix/include/m4..
5593 * m4/m4obstack.h: Renamed obstack.h, for same reason.
5594 * m4/m4regex.h: Renamed regex.h, for same reason.

5607 From Akim Demaille <akim@epita.fr>
5609 2000-01-17 Gary V. Vaughan <gary@gnu.org>
5611 * src/ltdl.c: Use access() to abort doomed module load attempts
5612 if module file does not exist.
5614 * src/Makefile.am (m4_SOURCES, EXTRA_SOURCES): getopt.o and
5615 getopt1.o will already be used if appropriate, so I moved getopt.c
5616 and getopt1.c from m4_SOURCES to EXTRA_SOURCES.
5618 * modules/modpath1.test: Use correct filename in header line.
5619 * modules/modpath2.test: ditto.
5620 * modules/modpath3.test: ditto.
5621 * modules/modpath4.test: ditto.
5623 Without these changes lt_dlopen("test") attempts to
5624 LoadLibrary("/bin/test") on Windows, which although harmless
5625 generates a spurious error message which spoils most of the tests:
5626 * modules/Makefile.am (EXTRA_DIST): s/test.m4 /modtest.m4 /
5627 (TESTS): s/test.test /modtest.test /
5628 (pkglibexec_LTLIBRARIES): s/test.la /modtest.la /
5629 (test_la_SOURCES, test_la_LDFLAGS): renamed to use modtest.
5630 * modules/modpath1.test: s/test.m4 /modtest.m4 /
5631 * modules/modpath2.test: ditto.
5632 * modules/modpath4.test: ditto.
5633 * modules/modpath3.test: s/-m test /-m modtest /
5634 * modules/shadow.m4: use {un,}loadmodule(`modtest').
5636 2000-01-16 Gary V. Vaughan <gary@gnu.org>
5638 * src/ltdl.c (find_file): Updated to new version with fixed memory
5639 allocation bug in `next'.
5640 * src/ltdl.h: updated to match.
5642 * modules/Makefile.am: Cleaned up and reordered.
5644 2000-01-16 René Seindal <rene@seindal.dk>
5646 * modules/Makefile.am (TESTS): New tests for the module system.
5648 * modules/*.test: New files.
5650 * src/m4.c (main): Added call to module_init().
5651 Treats -M and -m as the arguments -D -U and -t, ie deferred.
5653 * src/m4.h: Added declaration of module_init().
5655 * src/module.c (module_init): No longer static
5657 * modules/Makefile.am ({test,shadow,time,stdlib}_la_LDFLAGS):
5658 Added to shut up automake about non standard libtool library
5661 * src/module.c: Disabled DEBUG by default.
5663 * modules/README: Changed example from unload.m4 to shadow.m4
5665 * modules/shadow.m4: Renamed from unload.m4
5667 * modules/Makefile.am (EXTRA_DIST): Removed unload.m4.
5669 * src/m4.c (main): Functionality for -m and -M were reversed.
5672 2000-01-12 Gary V. Vaughan <gary@gnu.org>
5674 * doc/help2man.pl: updated to version 1.020.
5676 * lib/COPYING.LIB: updated to version 2.1.
5678 * lib/m4module.h: restructure the M4_SCOPE code to work when
5679 creating a dll which links with libm4.la and both DLL_EXPORT
5680 (for the new dll) and LIBM4_DLL_IMPORT (for m4module.h) are
5683 2000-01-11 Gary V. Vaughan <gary@gnu.org>
5685 Merged the following changes from my tree:
5687 1999-06-15 Gary V. Vaughan <gary@gnu.org>
5689 * configure.in (AC_LIBTOOL_WIN32_DLL): Declare that m4 has been
5690 ported to compile shared libs.
5692 * configure.in (LIBM4_DLL_IMPORT): Discover whether we need to
5693 use `__declspec(dllimport)' when linking libm4.la on win32.
5694 * src/Makefile.am (m4_LDFLAGS): Use dllimport if necessary.
5696 * configure.in (M4OBJS): Discover whether we need the shipped
5697 implementation of getopt_long.
5698 * src/Makefile.am (m4_LDADD): Link the getopt objects into the
5699 main binary here, as opposed to the module library in lib/libm4.la.
5701 1999-06-14 Gary V. Vaughan <gary@gnu.org>
5703 * modules/README: Updated to describe the improved libltdl based
5705 * README (cygwin): Added some compilation notes for building m4
5706 correctly under cygwin.
5707 * TODO: Cleaned out the entries for the module system since they
5708 are now implemented.
5710 * *.[ch]: __P is in the compiler's reserved namespace, so replaced
5711 all instances of __P with M4_PARAMS.
5713 * lib/getdate.h: removed unreferenced file.
5715 * lib/m4private.h: New file to define the private interface to the
5716 token_data struct, which must be shared between m4module.c, and
5717 builtin.c but not exported to modules built from the installed
5718 m4module.h since it's size changes depending on compile time
5721 * src/m4.h: Lots of stuff moved to lib/m4module.h.
5723 * lib/m4module.h: New file to define the interface available when
5724 compiling m4 modules.
5725 * lib/m4module.c: Moved parts of builtin.c, and m4.c which are
5726 necessary for module compilation into this new file.
5728 * lib/Makefile.am (include_HEADERS): install headers (renamed to
5729 avoid nameclash with other system headers) necessary for compiling
5731 (libm4_la_SOURCES): always include error.c, obstack.c and regex.c
5732 so that modules can include the (renamed) installed headers and
5733 be guaranteed a matching implementation.
5734 * lib/m4error.h: renamed from error.h.
5735 * lib/m4obstack.h: renamed from obstack.h.
5736 * lib/m4regex.h: renamed from regex.h.
5737 * configure.in (AC_REPLACE_FUNCS): Don't look for a system
5738 implementation, simply include the shipped version
5739 unconditionally, otherwise it is hard for a module to know
5740 whether the m4obstack.h header it is using matches the
5741 implementation it ends up linking against.
5742 (jm_WITH_REGEX): Include regex into libm4 unconditionally for
5745 1999-05-18 Gary V. Vaughan <gary@gnu.org>
5747 * examples/misc.test: Don't run this test on machines which don't
5748 have a root user in /etc/passwd (e.g. cygwin).
5750 * tests/get-them (/^@example$/): Error messages might have a
5751 ``.exe'' suffix to the program name, or else use the libtool
5752 ``.libs/lt-m4'' binary, or generally have an unexpected path. All
5753 of these cases are now catered for when comparing error messages
5755 * tests/other-tests/*.test: ditto.
5756 * examples/*.test: ditto.
5758 * tests/defs (M4): use libtool execute mode.
5759 * examples/defs (M4): ditto.
5761 * tests/get-them (END): explicitly close any open file.
5762 (printthem): In a regular expression, '{' is the start of a repeat
5763 count! Use `[{]' for a literal open brace.
5764 (/^@node /): Don't use substr on a string shorter than the trim
5767 1999-05-17 Gary V. Vaughan <gary@gnu.org>
5769 * configure.in (LTLIBOBJS): calculated from LIBOBJS, and
5771 (AC_LIBTOOL_DLOPEN): declare that this package will use dlopen.
5773 2000-01-10 Andreas Schwab <schwab@suse.de>
5775 * tests/other-tests/gmp.test: Find config.sh in build directory.
5777 * configure.in: Find tests/mkconfig.sh in $srcdir.
5779 * configure.in: Define HAVE_SIGINFO_T if siginfo_t is defined in
5780 <signal.h> (for SUS2 compliant systems).
5782 * src/stackovf.c: Check for HAVE_SIGINFO_T in addition to
5785 2000-01-10 René Seindal <rene@seindal.dk>
5789 * TODO, NEWS: Cleaned up and updated.
5791 * src/m4.c (main): New variable exit_status for exit status in
5792 case of unreadable files. Now m4 will exit with EXIT_FAILURE if a
5793 file cannot be read instead of EXIT_SUCCESS.
5795 * src/builtin.c (m4_indir): Changed error message to help
5796 translators (from Akim Demaille <demaille@inf.enst.fr>).
5798 * lib/obstack.[hc], getopt*.[ch]: Updated to newest version from
5801 * lib/error.[hc], lib/regex.[hc], lib/strtol.c: Updated to version
5804 * src/input.c (match_input): Reordering of code, to avoid multiple
5805 calls to push_string_init() from obstack_grow(), which can happen
5806 with some compilers (found and fixed by James Bonfield
5807 <jkb@mrc-lmb.cam.ac.uk>).
5809 * src/stackovf.c: Added prototypes for ultrix.
5810 (setup_stackovf_trap): Added __P to cast.
5811 (Both reported by John David Anglin <dave@hiauly1.hia.nrc.ca>)
5813 2000-01-09 René Seindal <rene@seindal.dk>
5815 * doc/m4.texinfo (Changequote): Added comment about changing
5816 quotes when the old quote is a part of the new.
5818 * src/builtin.c (expand_ranges): Added break after trailing dash.
5819 This caused misbehavious on some systems (found and fixed by Akim
5820 Demaille <demaille@inf.enst.fr>).
5822 * AUTHORS: Thomas Tanner included
5824 * acconfig.h: Added entry for ss_sp (see below).
5826 * configure.in (use_stackovf): Added check for stack_t with member
5827 ss_base instead of ss_sp (BSDI notably). (Reported by Paul Eggert
5828 <eggert@twinsun.com>).
5830 * doc/m4.texinfo (Frozen files): Added a simpler example for
5831 generating frozen files from several input files.
5833 1999-11-14 Paul Eggert <eggert@twinsun.com>
5835 * po/POTFILES.in: Add lib/getopt.c, lib/obstack.c,
5836 lib/regex.c, lib/xmalloc.c.
5838 1999-11-10 René Seindal <rene@seindal.dk>
5840 * Makefile.am (ACLOCAL_AMFLAGS): Passes -I acm4 to aclocal.
5842 * src/module.c: reindented.
5843 (module_load): return if this is a repeated load of same module.
5844 (module_init): slight change of logic to avoid repeated
5845 initialisation debug messages.
5847 * Makefile.am (DIST_SUBDIRS): Added to ensure modules/ is included
5848 in the distribution.
5850 * modules/Makefile.am (test_la_LDFLAGS): set to -module to silence
5851 automake warnings about missing lib prefix.
5852 (time_la_LDFLAGS): ditto
5853 (stdlib_la_LDFLAGS): ditto
5855 1999-11-10 Paul Eggert <eggert@twinsun.com>
5857 * src/m4.h: Include error.h, since our macros use error.
5858 * src/m4.c: Don't need to include error.h.
5860 1999-11-09 Paul Eggert <eggert@twinsun.com>
5862 * src/m4.h (voidstar): Define to void * if __STDC__ is defined
5863 and zero, as Solaris 7 cc does.
5864 (bcopy): Remove macro; no longer needed with new obstack.h.
5866 * src/output.c (freeze_diversions): Don't assume that a
5867 diversion size can fit in `int'. Check for diversion file
5868 size too large to be printed with `unsigned long'.
5870 * src/Makefile.am (CFLAGS): Omit -Wall.
5872 * src/stackovf.c (setup_stackovf_trap): Remove cast to unsigned.
5874 * src/debug.c (trace_format):

5900 * src/module.c: entirely new implementation using libltdl.
5901 * po/POTFILES.in: added src/module.c.
5902 * modules/Makefile.am (LTLIBRARIES): Removed lib prefix as these
5903 are modules, not linktime libraries.
5904 (LDFLAGS): added -no-undefined -module and -avoid-version flags.
5905 * modules/stdlib.c (m4_macro_table): use <name>_LTX collision
5906 avoidance on exported symbols.
5907 * modules/test.c (m4_macro_table, m4_init_module,
5908 m4_finish_module): ditto.
5909 * modules/time.c (m4_macro_table): ditto.
5911 * modules/time2.m4: new file which requires command line loading
5913 * src/m4.c (--load-module): dynamically load named runtime module
5914 into running executable before reading the source.
5915 (--module-directory): prepend a directory to the module search
5917 (module_init()): Do this the first time we load a module instead;
5918 if the module subsystem is broken normal m4 scripts can still run.
5919 * src/m4.h (install_builtin_table): is now exported.
5921 1999-03-26 Gary V. Vaughan <gary@gnu.org>
5923 * src/module.c: removed. No longer required.

5934 * src/Makefile.am (MAINTAINERCLEANFILES): ditto.
5935 * tests/Makefile.am (MAINTAINERCLEANFILES): ditto.
5937 * acinclude.m4: removed. `aclocal -I acm4' handles this much
5939 * acm4/Makefile.am (ACINCLUDE_M4): ditto.
5940 * acm4/gettext.m4: removed. It causes a multiple definition vs.
5941 the installed gettext.m4 file when running aclocal.
5943 1999-03-25 Gary V. Vaughan <gary@gnu.org>
5945 * configure.in (AM_INIT_AUTOMAKE): bumped version number to

5947 (AC_LIBLTDL_CONVENIENCE): build libltdl as a convenience library
5948 in its own subdirectory.
5950 * modules/Makefile.am (*_SOURCES): renamed to use libtool's "no
5951 lib prefix on a module" feature.
5952 (LDFLAGS): Added `-module -avoid-version' flags to build
5953 versionless module libraries.

5955 (module_unload_all): use libltdl.
5956 * src/m4.c (module_init): initialise module loading on demand for
5957 better diagnostics, and so that m4 will still work even if
5958 the module code is broken.
5959 * src/m4.h (module_init): removed. No longer relevant.
5960 * modules/stdlib.c (m4_macro_table): use stdlib_LTX_ prefix on

5963 m4_finish_module): ditto.
5964 * modules/time.c (m4_macro_table): ditto.
5966 * bootstrap: New file. Runs all the autoutils in the right order
5967 after a fresh checkout, or a make maintainer-clean.
5969 1999-02-18 Akim Demaille <demaille@inf.enst.fr>
5971 * src/builtin.c (dump_symbols): New function, factoring common
5972 content of m4_dumpdef and m4_symbols.
5973 (m4_dumpdef): Use it.
5974 (m4_symbols): New function, implementing `symbols'. Use it.
5975 * doc/m4.texinfo: Fixed missing commas after @xref, so that the
5976 file compile with modern makeinfo.

5978 (direntry): Modernize.
5980 1998-12-11 René Seindal <rene@seindal.dk>
5982 * src/builtin.c (predefined_tab): New predefined macros
5983 __m4_changeword__, __m4_gmp__ and __m4_modules__ for testing for
5984 configure time options.
5986 1998-12-01 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
5988 * src/module.c (module_try_load): Don't try to be clever and
5989 overwrite argument string. Instead allocate all constructed
5990 strings locally, since they can have arbitrary lengths. Make
5991 arguments pointers to const.
5992 (module_search): Simplify due to above change.
5994 1998-11-29 René Seindal <rene@seindal.dk>
5998 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): New tests.

6010 discarded, ie never returned from next_token().
6011 Added declaration of discard_comments.
6013 * src/input.c (next_token): Now loops until token type is not
6014 TOKEN_NONE. Comments are now given this type when comments should
6017 * doc/m4.texinfo (Invoking m4): Updated for --import-environment
6020 1998-11-28 René Seindal <rene@seindal.dk>
6022 * src/m4.c (main): New option --import-environment (no single
6025 * When configured with --with-gmp both the normal (fast) eval()
6026 and the gmp aware mpeval() are defined. To restore previous
6027 bahaviour use "define(`eval', defn(`mpeval'))".
6029 * tests/other-tests/gmp.m4: Changed to use mpeval().
6031 * src/evalmp.c: New file for compiling eval.c as gmp aware.
6032 Just defines USE_GMP if WITH_GMP is defined and includes eval.c.
6034 * src/eval.c: Now includes "numb.c" directly. Everything in this
6035 file must by static, except evaluate(), which is changed to
6036 mp_evaluate() if USE_GMP in force.
6038 * src/numb.c: Changed to be included by eval.c instead of being
6039 compiled separately. Everything is declared static.
6041 * src/numb.h: Removed declarations of functions, as numb.c is now
6044 * src/builtin.c: Declaration of m4_mpeval() added.
6045 Inserted `mpeval' in builtin table.
6046 (do_eval): New function with common code for m4_eval and m4_mpeval.

6052 (EXTRA_m4_SOURCES): Now has numb.c and numb.h
6054 * src/m4.c (main): m4 --version also shows which options were used
6055 for compilation, such as: "GNU m4 1.4n (options: modules gmp)"
6057 1998-11-27 René Seindal <rene@seindal.dk>
6059 * Error messages now always print program name before input file
6060 name as specified by GNU coding standards. Reported by Akim
6061 Demaille <demaille@inf.enst.fr>.
6063 * doc/m4.texinfo (Include): Change due to changed error message
6067 * tests/get-them: Minor change to sed script due to changed error
6070 * src/m4.c (print_program_name): New func used to print program
6071 name, input file and line number in error (). Used as an
6072 error_print_progname handler.
6073 (reference_error): Removed.
6074 (main): Assigns error_print_progname.
6076 * src/m4.h (M4ERROR): Removed reference_error ().
6078 1998-11-25 René Seindal <rene@seindal.dk>
6080 * Updated to libtool 1.2b.
6082 * src/builtin.c (install_builtin_table): Added braces to avoid
6083 warning of ambiguous 'else'.
6085 * src/module.c: Inserted search path code from path.c modified to
6087 (module_init): Configured default path used only if M4MODPATH is
6089 (module_try_load): Now reads libMODULE.la as generated by libtool
6090 for actual module name.
6091 (module_load): Gives better error messages on failure.
6093 * src/m4.h: Added declarations of structures and functions for
6094 generic search path handling.
6096 * src/path.c: Removed all module specific code and introduced new
6097 functions of more generic search path handling.
6099 1998-11-24 René Seindal <rene@seindal.dk>
6101 * configure.in: Defines INTLINCL to -I$(top_srcdir)/intl if using
6102 included gettext, as <libintl.h> might not be found
6103 otherwise. Reported by Andrew Bettison <andrewb@zip.com.au>.
6105 1998-11-22 René Seindal <rene@seindal.dk>
6107 * src/output.c (insert_diversion): Fixed bug that might cause m4
6108 to read from standard output! Triggered by input
6109 'divert(1)undivert(0)'. Test for divnum>0 changed to divnum>=0,
6110 so now 'undivert(0)' does nothing.
6112 1998-11-18 René Seindal <rene@seindal.dk>
6116 * src/input.c (set_word_regexp): Fixed a bug, where word_regexp
6117 could be changed when compiling a illegal regexp, causing later
6118 use of the regexp to dump core.
6120 * src/module.c (module_load): Changed error message to conform to
6123 * src/m4.c (usage): Added message about reporting bugs.
6125 * doc/m4.texinfo (Changeword): Corrected a wrong example.

6133 * acm4/modules.m4 (AM_WITH_MODULES): Redone completely to work
6136 * modules/Makefile.am: Changed completely to compile modules using
6137 libtool. The modules are compiled as shared libraries, and are
6138 renamed when installed.
6140 * src/m4.h, src/module.c, acm4/modules.m4, acconfig.h: Renamed
6141 USE_SHL_LOAD to HAVE_SHL_LOAD
6143 * src/builtin.c (shipout_string): Now tests for a NULL string.

6146 functions to load shared objects. Intended to encapsulate the non
6147 portable parts better and to reduce the number of #ifdefs in the
6150 * Makefile.am (DIST_SUBDIRS): Instead of EXTRA_DIST for added
6151 directory modules/ to the distribution.
6153 1998-11-15 René Seindal <rene@seindal.dk>
6157 * modules/stdlib.c: New module `stdlib' defining some standard
6158 functions: getcwd, getlogin, getpid, getppid, getuid, getpwnam,
6159 getpwuid, hostname, rand, srand, getenv, setenv, unsetenv, uname.
6161 * src/builtin.c (shipout_string): New convenience function for
6162 builtins and modules.
6164 * src/module.c (module_load): Tentative support for
6165 shl_load/shl_findsym, but I cannot test it. Copied from MetaHTML.
6167 * Makefile.am (SUBDIRS): Directory modules added if configured.
6169 * modules/Makefile.am: Now correctly compiles and installs
6170 modules in pkglibexecdir.

6173 These two are now initialised by autoconf macros.
6175 * src/path.c (module_env_init): MODULE_PATH is always on the
6178 * src/Makefile.am: Now generated pathconf.h which defined the
6179 default MODULE_PATH.
6181 * configure.in (pkglibexecdir): Added defintion of pkglibexecdir,
6182 where modules are installed.
6184 * acm4/modules.m4: Enhanced with code from MetaHTML, contributed
6185 by Brian J. Fox <bfox@datawave.net>. This change allow modules to
6186 build and install automatically, and it is prepared for other
6187 interfacec than dlopen().
6189 * src/builtin.c (predefined_tab): Added __m4_version__ for the
6190 current version of GNU m4. It is a GNU extension.

6222 * tests/Makefile.am (GENERATED_TESTS): Renamed gentest to
6225 * tests/Makefile.am (OTHER_TESTS, OTHER_FILES): Added manually
6226 maintained tests in tests/other-tests. These currently tests for
6227 8-bit transparency, multiple precision arithmetic and sync-line
6228 output. Test for stackoverflow detection does not work.

6268 * src/builtin.c (builtin_tab): Builtin format marked as blind.
6270 1998-10-07 René Seindal <rene@seindal.dk>
6274 * tests/Makefile.am (GENERATED_TESTS): Changed .m4 extension to
6275 .test, as the files are no longer just m4 input.
6277 * tests/get-them (FILE): Changed .m4 extension to .test.
6279 * src/m4.h (token_type): New token type TOKEN_SPACE introduced.
6280 Otherwise quoted strings with leading whitespace first in a macro

6283 * src/macro.c (expand_token): Handles new token type TOKEN_SPACE.
6284 (expand_argument): Do.
6286 * src/input.c (next_token): SPACE and NUM/OTHER characters are only

6288 character. Otherwise they might include a comment/quote leader.
6289 (next_token): Returns new token type TOKEN_SPACE.
6291 * src/builtin.c (push_builtin_table): New function to push a
6292 builtin_table on the stack without installing its contents.
6293 (find_builtin_by_name): Added call to push_builtin_table() if
6294 reading frozen files. Otherwise the builtins named in the frozen
6295 files could not be found.

6320 * src/builtin.h: New file, declares some functions from builtin.c
6321 that are of use for other modules (shipout_int, numeric_arg,
6322 skip_space, bad_argc), and the macros ARG() and DECLARE().
6324 * src/builtin.c (install_builtin_table): New function. Each
6325 module brings in a builtin_table, which is pushed on a stack.
6326 (struct builtin_table): New struct for list of builtin_tables.
6327 (m4_loadmodule): New function to implement builtin "loadmodule".
6328 (shipout_int): No longer static, to be used by modules.

6349 * configure.in: Added modules/Makefile to AC_OUTPUT.
6351 * configure.in: Added code to implement --with-modules. Tests for
6354 * acconfig.h: Added WITH_MODULES
6356 1998-10-02 René Seindal <rene@seindal.dk>
6358 * examples/Makefile.am (pkgdata_DATA): Removed special target for
6359 check and variables TESTS. These tests are now run from the
6362 * tests/Makefile.am (OTHER_TESTS): Added tests from the example/
6363 directory. The files stay there but the tests are run from the
6366 * tests/Makefile.am (EXTRA_DIST): Added run-test.
6368 * tests/run-test: New file. Run a test manually
6370 * tests/Makefile.am, tests/get_them: Moved automatically generated
6371 tests (from the manual) to sub directory tests/gentest/. The
6372 tests/ directory had gotten a bit messy.
6374 1998-09-06 Erick Branderhorst <Erick.Branderhorst@asml.nl>
6376 * examples/{comments,ddivert,debug,iso8859,reverse,sysv-args,\
6377 wrap}.test: Added a few testcases.
6379 1998-08-21 Erick Branderhorst <Erick.Branderhorst@asml.nl>
6383 * lib/Makefile.am (noinst_HEADERS): regex.h added
6385 * configure.in (jm_WITH_REGEX, jm_PREREQ_ERROR):
6386 acm4/{error,regex}.m4 (from fileutils-3.16u.tar.gz).
6388 * acm4/Makefile.am: created providing rules to create
6389 $(top_srcdir)/acinclude.m4 to be used by aclocal.
6391 * tests/defs (LANGUAGE, LC_ALL, LANG): force them to be
6392 `C'. Reported by Ulrich Drepper.
6394 * Makefile.am (SUBDIRS): Removed checks directory
6395 * configure.in (AC_OUTPUT): Removed checks/Makefile
6397 * doc/m4.texinfo (Patsubst,example): @comment added to preserve
6398 the space when m4.texinfo is edited and whitespace.el is active.
6399 (Defn,example): idem.
6401 1998-08-20 Erick Branderhorst <Erick.Branderhorst@asml.nl>
6403 * doc/m4.texinfo (Esyscmd): grep ../Makefile instead of
6404 ../COPYING. ../Makefile is a file which is certainly present when
6405 test is executed in testSubDir. One can't be sure that the COPYING
6406 file is in .. or ../.. in all situations, the ../Makefile is
6409 * doc/m4.texinfo (Include): adjusted expected test output
6410 according to new tests, i.e. the input will always come from the
6411 file `in' created by the test.
6413 * tests/Makefile.am: Added three lines at the top to get
6414 esyscmd.1.test working.
6416 * tests/get-them: modified to generate clearer tests who will need
6417 less maintenance when new test examples are created in
6418 `doc/m4.texinfo'. All tests are small (nearly stand-alone, they
6419 need the generic file `defs') shell scripts creating `in', `ok',
6420 `out' and when apropriate `okerr' and `err' in the directory
6421 `testSubDir' when executed. The compare of `ok' and `out'
6422 (and of `okerr' and `err') will be the exit status of the test.
6423 `out' must match `ok' (and `okerr' must match `err') for the test
6426 * tests/[a-b]\{1,8\}.[0-9]+.test: This namespace is reserved for
6427 the tests generated by tests/get-them getting it input normally
6428 from doc/m4.texinfo. The namespace tests/[a-b]+[0-9]+.test (no `.'
6429 (dot) before the numeric part) is reserved for all other (hand
6430 written) tests. The `+' means one or more times.
6432 1998-08-12 Erick Branderhorst <Erick.Branderhorst@asml.nl>
6434 * doc/Makefile.am (EXTRA_DIST): helptoman.pl and $(MANS) to
6435 supported short man page to refer to info documentation
6436 * helptoman.pl: added
6437 * configure.in: AC_PATH_PROG(PERL,perl)
6438 * Makefile.am (SUBDIRS): doc after src
6440 * libitized with libit 0.5 from
6441 ftp://ftp.iro.umontreal.ca/pub/contrib/pinard/maintenance/libit.

6448 * configure.in (AC_CHECK_FUNC): getopt_long
6450 * src/m4.c (usage): Report bugs to m4-bugs@gnu.org.

6461 * src/builtin.c (m4_changesyntax): Added builtin macro
6462 "changesyntax" to modify the syntax table.
6464 * src/input.c, src/m4.h, src/macro.c: Implemented an input syntax
6465 table. All categories are assigned a syntax code and tokens are
6466 read according to this table.
6468 1998-08-09 René Seindal <rene@seindal.dk>
6470 * src/numb.{c,h}: New files, implements multiple precision eval
6471 using GNU gmp. Originally submitted by John Gerard Makecki
6472 (johnm@vlibs.com), later modified. Tested with GNU gmp 2.0.2.
6474 * doc/m4.texinfo (Eval): Added documentation for multiple
6475 precision arithmetic library support.
6477 * src/m4.{c,h}, src/eval.c, src/builtin.c, configure.in: Changes
6478 to accommodate multiple precision eval.
6480 1998-08-07 René Seindal <rene@seindal.dk>
6482 * src/input.c (MATCH, match_input), src/m4.h: changed definition
6483 of comment and quote strings to `unsigned int' to allow eight bit
6484 chars (reported by andrewb@zip.com.au (Andrew Bettison)).
6486 * src/builtin.c, doc/m4.texinfo: Builtin `syncoutput' added by
6487 patch from Mike Howard <mike@clove.com>
6489 1998-08-06 René Seindal <rene@seindal.dk>
6491 * gettext.m4: corrected AM_WITH_NLS to handle use of installed
6494 1998-08-03 René Seindal <rene@seindal.dk>
6498 * src/m4.h: Added ifdef ENABLE_NLS around include of <libintl.h>
6499 and _ macro. M4 now builds with --disable-nls.
6501 * src/m4.c (main): reintroduced textdomain(PACKAGE) to get gettext
6502 to look for right message catalogs. Call indef'ed by ENABLE_NLS.
6504 * configure.in (ALL_LINGUAS): Added complete list of translations:
6505 de fr it ja nl ru sv.
6507 1998-05-23 Erick Branderhorst <Erick.Branderhorst@asml.nl>
6509 * po/nl.po: Dutch translation by Erick Branderhorst.
6511 * po/fr.po: French translation by Erick Branderhorst, based on the
6512 translations by François Pinard in fr.msg and m4.cod.
6514 1998-05-22 Erick Branderhorst <Erick.Branderhorst@asml.nl>
6518 * src/m4.c: #include <signal.h> not <sys/signal.h>.
6520 * src/Makefile.am: CFLAGS = -Wall @CFLAGS@.
6522 * checks/Makefile.am: explicit list tests in CHECKS.
6524 * configure.in, {,src,doc,lib,examples,checks}/Makefile.am,

6528 * lib/{alloca.c,error.{c,h},get{date.h,opt.{c,h},opt1.c},
6529 obstack.{c,h},regex.{c,h},strtol.c,xmalloc.c,xstrdup.c}:
6530 Used libitize (0.4) to update.
6532 * configure.in, ABOUT-NLS, intl/*, po/*: Added gettextize
6533 (0.10.25) support. Removed LOCALE, fr.msg, m4.cod and adjusted

6584 be opened, return immediately after producing the error message.
6585 Reported by Andreas Schwab.
6587 * configure.in: Check for const only after having found possible
6588 ANSIfying compiler flags, this is of no use to check it before.
6589 Reported by Alexander Lehmann.
6591 1994-11-01 François Pinard <pinard@iro.umontreal.ca>
6593 * src/macro.c (collect_arguments): Cast obstack arguments to
6594 (voidstar), so avoiding compiler warnings.
6595 Reported by Joseph E. Sacco.
6597 * src/freeze.c (produce_frozen_state): Cast printed lengths to
6598 (int) so they correspond to %d format items.
6599 Reported by Joseph E. Sacco.
6601 * src/m4.c (main): Cast the argument to xfree to (voidstar).
6602 * src/symtab.c (free_symbol): Idem.

6616 * src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
6617 __STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
6618 defines __STDC__ to 0, for indicating it is *not* ANSI!
6619 Reported by Kaveh R. Ghazi.
6621 * configure.in: Added obsolescent tests for AIX and Minix.
6623 * doc/Makefile.in (mostlyclean): Remove texclean in dependencies,

6637 Remove the sed filter after ansi2knr for debug.c. Use $O instead
6638 of $U, put underline in extensions rather than in basenames. Use
6639 implicit rules, now that regularity makes this possible.
6640 Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
6641 of ansi2knr whenever it is needed.
6642 * configure.in: Adjusted for correct STACKOVF substitution.
6643 * src/debug.c (trace_format): When not __STDC__, use (...) as a

6689 configure does it automatically.
6690 Reported by Jim Meyering.
6692 1994-09-23 François Pinard <pinard@iro.umontreal.ca>
6694 * src/stackovf.c: Declare the handler_t typedef earlier in the

6727 * Makefile.in (distclean, realclean): Instead of recursively
6728 calling $(MAKE) for the -local part, allow parallel execution of
6729 -recursive and -local, only delay the removal of config.status,
6730 which is repeated in both goals.
6732 1994-09-13 François Pinard <pinard@iro.umontreal.ca>
6736 * Makefile.in: Group all *clean-recursive goals in one, using sed
6737 to remove `-recursive' while calling make recursively. Also, use
6738 a subshell for each recursive $(MAKE).
6739 Reported by Jim Meyering.

6742 Reported by Kaveh R. Ghazi.
6744 * src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS

6803 * src/m4.c: Have -P set prefix_all_buitins variable instead of
6804 calling a function by that name. Declare the variable.
6805 * src/m4.h: Adjust declaration for prefix_all_buitins.
6806 * src/builtin.c (builtin_init): Merge in functionality from
6807 previous prefix_all_buitins function, while making entries in the
6808 symbol table, but not modifying the builtin description itself.
6810 * src/freeze.c (reload_frozen_state): Add a useless `break;',
6811 because *many* compilers do not accept an empty `default:'.
6812 Reported by Akiko Matsushita, Eric Backus, John David Anglin,
6813 Joseph E. Sacco, Kaveh R. Ghazi, Tom McConnell and Ulrich Drepper.

6825 functions, for implementing a global MAXIMUM_TOTAL_SIZE instead of
6826 a per buffer MAXIMUM_BUFFER_SIZE.
6828 * src/output.c (output_text): New function, for optimizing the
6829 output of strings of characters. Use it.
6831 1994-08-30 François Pinard <pinard@iro.umontreal.ca>

6836 * Makefile.in: Adjusted.
6837 * configure.in: Configure new Makefiles.
6839 * m4.h: Declare STRING typedef. Use it for comment and quote
6840 strings, adjusting all references. (This is the rudiments of a
6841 beginning for the eventual withdrawal of NUL terminated strings.)
6842 * output.c (shipout_text): Accept a length parameter, and use it.
6843 All callers adjusted.
6845 1994-08-29 François Pinard <pinard@iro.umontreal.ca>

6864 Reported by David MacKenzie.
6867 * output.c (freeze_diversions): New function.
6868 * m4.h: Declare freeze_diversions.
6869 * freeze.c: Document frozen file format, revise it, call
6870 freeze_diversions to add diversions to frozen format, and code to
6871 reload them properly.
6872 * m4.c: Do not undivert automatically at end when status being
6873 frozen. Do not call builtin_init when reloading frozen state.
6875 Speed up diversion processing:
6876 * output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,
6877 COPY_BUFFER_SIZE, in-memory diversion buffers, struct diversion
6878 structure and variables, cached variables out of output_diversion,
6879 reallocate_diversion_for and OUTPUT_CHARACTER.
6880 (shipout_text, make_diversion, insert_diversion): Adapted to new

6890 1994-08-27 François Pinard <pinard@iro.umontreal.ca>
6892 * symtab.c (hack_all_symbols): Use hash_table_size instead of

6895 * builtin.c (DECLARE): Simplify by using _ ().
6897 * freeze.c: New file.
6898 * Makefile.in: Compile it, distribute it.
6899 * m4.c: Recognize, document and process --freeze-state (-F) and
6900 --reload-state (-R) options. Pass a true flag to builtin_init
6901 only if no reloading some state.
6902 * builtin.c (define_builtin): Remove static specifier.
6903 (find_builtin_by_name): Remove static specifier.

6919 Reported by Akiko Matsushita.
6921 1994-08-12 François Pinard <pinard@iro.umontreal.ca>
6923 * m4.h: Include <sys/types.h>.
6924 * builtin.c, debug.c, m4.c, output.c, stackovf.c: Don't.
6925 * m4.h: Declare len_lquote and len_rquote as size_t, not int.
6927 * input.c: Declare len_lquote, len_rquote, len_bcomm and len_ecomm
6929 * builtin.c (dump_args): Declare len as size_t, not int.
6931 * debug.c: Prototype the forward declaration of debug_set_file.
6933 * builtin.c (m4_undivert): Replace div by file, for avoiding the
6934 shadowing of this variable.
6935 * output.c (insert_diversion): Idem.
6937 * input.c: Delete def_rquote, def_lquote, def_bcomm and def_ecomm.
6938 (input_init): Duplicate default quote and comment strings.

6947 * m4.c (usage): Reorganize the --help output by topic. Include a
6948 description for debugging flags.
6950 1994-07-29 François Pinard <pinard@iro.umontreal.ca>
6952 * configure.in: If sigaction is available and SA_ONSTACK defined,
6953 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK
6954 defined, use sigvec. Else don't compile stackovf.c.
6955 * stackovf.c (setup_stackovf_trap): Idem.
6956 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe
6959 1994-07-21 François Pinard <pinard@iro.umontreal.ca>

6963 1994-07-18 François Pinard <pinard@iro.umontreal.ca>
6967 1994-07-17 François Pinard <pinard@iro.umontreal.ca>
6969 * configure.in: Check for sigaction and sigvec. Add a new delayed
6970 check for RLIMIT_STACK, combine in the checking for getrlimit.
6971 All those things are not universally available.
6972 * stackovf.c: Split setting up the trap handler and catching
6973 signals, for better taking care of various configure outcomes.
6974 * examples/stackovf.sh: Correct a typo.
6975 Reported by Eric Backus, Jim Avera and Jim Meyering.
6977 1994-07-16 François Pinard <pinard@iro.umontreal.ca>
6979 * ansi2knr.c: New version sent by its author, Peter Deutsch.
6981 1994-07-15 François Pinard <pinard@iro.umontreal.ca>
6983 * Makefile.in: Modify so parallel make will not try making
6984 lib/libm4.a twice simultaneously.
6985 Reported by Jim Meyering.
6987 1994-07-14 François Pinard <pinard@iro.umontreal.ca>
6989 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in
6990 error message, for when no code possibility exists. Even if this
6991 line is completely #ifdef'ed out, it brings a syntax error.
6992 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco.
6994 * Makefile.in (install): Have install depend on all too, for lib
6995 to be remade as needed.
6997 * examples/stackovf.sh: Try ksh, bsh and bash for shells
6998 providing ulimit, instead of using only ksh.
6999 Reported by Jim Avera and Joseph E. Sacco.
7001 1994-07-12 François Pinard <pinard@iro.umontreal.ca>
7003 * Makefile.in (check): Have it depend on all instead of m4. In
7004 this way, a change in lib will be detected and processed.
7006 * builtin.c (numeric_arg): Use strtol and verify the conversion,
7007 instead of using sscanf which stops as soon as there is a
7008 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy)
7009 and divert(1xyzzy) were all accepted without any warning or error
7011 * m4.h: Declare strtol as long if not including stdlib.h.
7012 * configure.in: Check for limits.h, and replace strtol if missing.
7013 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c.
7014 * lib/strtol.c: New file, from elsewhere.
7015 Reported by Andreas Schwab.
7017 1994-07-07 François Pinard <pinard@iro.umontreal.ca>
7019 * macro.c (expand_macro): Cast value to (boolean) prior to
7020 assigning it to traced.
7021 Reported by Tom McConnell.
7023 * Makefile.in (m4): Always make all in lib first.
7024 Reported by Jim Meyering.
7026 1994-07-06 Jim Avera <jima@netcom.com>
7028 * stackovf.c: Isolated OS-dependent sections; Improved portability,
7029 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal
7030 handlers), and a default error message if the fault address is not
7031 available (when neither siginfo.h nor BSD sigcontext are supported).
7032 * configure.in: Changes for stackovf.h: Check for sigcontext,
7033 sigaction, sigstack, and define rlim_t as int if necessary.
7034 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
7035 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
7036 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.
7038 1994-07-05 François Pinard <pinard@iro.umontreal.ca>
7040 * configure.in: Use AC_SET_MAKE.
7041 * Makefile.in: Use @SET_MAKE@.

7045 Reported by Ian Taylor.
7047 1994-07-02 François Pinard <pinard@iro.umontreal.ca>
7049 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
7050 because siginfo.h is unrelated to standard headers, and siginfo.h
7051 is already checked for.
7052 Reported by Joseph E. Sacco.
7054 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by
7056 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
7059 1994-06-29 François Pinard <pinard@iro.umontreal.ca>
7061 * builtin.c (substitute): Use \& to represent this part of the
7062 string which was matched by the whole regexp, instead of
7063 representing the whole string. Any usage of \0 issues a warning
7064 and acts like \&, it will disappear in some subsequent release.
7066 1994-06-27 François Pinard <pinard@iro.umontreal.ca>
7068 * m4.c: Complete prototype for forwarded declaration of usage.
7070 * input.c (init_macro_token): Correct own reference in error
7071 message. Previous name get_macro_func was referred to instead.
7072 (next_char): Correct own reference in error message. Previous
7073 name advance_input was referred to instead.
7075 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
7076 * eval.c (logical_or_term, logical_and_term, or_term, xor_term,
7077 and_term, not_term, logical_not_term, cmp_term, shift_term,
7078 add_term, mult_term, exp_term, unary_term, simple_term): Add
7079 prototype to forwarded declarations. Declare parameter v1 as
7080 eval_t * instead of int *. Same for local variable v2 in dyadic
7081 functions. Same for result in exp_term.
7082 * builtin.c (m4_eval): Declare value as eval_t instead of int.
7083 (ntoa): Declare value as eval_t instead of int. Declare uvalue as
7084 unsigned_eval_t instead of unsigned int. Change casts accordingly.
7085 (shipout_int): Cast first argument of ntoa to eval_t.
7086 Reported by Thorsten Ohl.
7088 * macro.c: Complete the prototypes of forwarded expand_macro and
7090 Reported by Thorsten Ohl.
7092 * m4.h: Define voidstar as void * or char * depending on __STDC__.
7093 The Ultrix 3.1 compiler cannot do much with void pointers.
7095 * builtin.c (dumpdef_cmp): Replace void * by voidstar.
7096 * m4.c (xfree): Replace void * by voidstar.
7097 Reported by Tom McConnell.
7099 * ansi2knr.1: New, from elsewhere.
7100 * Makefile.in (DISTFILES): Distribute ansi2knr.1
7102 * Makefile.in (stamp-h.in): Avoid running ./config.status if
7103 stamp-h does not exist yet. This avoids running it a second time
7104 just after the initial ./configure.
7105 Reported by David MacKenzie and Tom McConnell.
7107 * m4.h: Replace the enum debug_info declaration with a series of
7108 #define's. The Ultrix 3.1 compiler would otherwise need casting
7109 (int) to most references, when used in expressions.
7110 Reported by Tom McConnell.
7112 1994-06-25 François Pinard <pinard@iro.umontreal.ca>
7114 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
7115 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
7116 calls the compiler. Previously, FP_PROTOTYPES was only calling
7117 the preprocessor; by not being subject to CFLAGS, this was
7118 discouraging those flags asking for ANSI compilation.
7119 * acconfig.h: Document HAVE_PROTOTYPES.
7120 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
7121 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.
7122 Reported by Eric Backus.
7124 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value
7125 from the environment. Default CFLAGS to -g if not set.
7126 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure.
7127 * lib/Makefile.in: Have CFLAGS substituted from configure.
7128 Reported by Eric Backus and Tom McConnell.
7130 * configure.in: m4_undefine changeword before using AC_ENABLE.
7132 * m4.h: Declare prototypes for error (for ANSI compilers only),
7133 prefix_all_builtins and reference_error.
7134 Reported by Tom McConnell.
7136 * input.c (set_word_regexp): Do not try to initialize the array
7137 test from a string, this does not work with non-ANSI compilers.
7138 Reported by Eric Backus.
7140 * Makefile.in (dist): Clean examples/ before saving it.
7141 (distclean-local): Also remove stamp-h.
7142 Reported by Eric Backus.
7144 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
7146 Reported by Tom McConnell.
7148 * checks/Makefile.in (clean): Depends on mostlyclean.
7149 (mostlyclean): New goal.
7151 1994-06-24 François Pinard <pinard@iro.umontreal.ca>
7153 * Makefile.in (DISTFILES): Distribute install.sh.
7154 * install.sh: New file, copied from elsewhere.
7155 Reported by Assar Westerlund and Kaveh R. Ghazi.
7157 1994-06-23 François Pinard <pinard@iro.umontreal.ca>
7159 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword.
7160 * acconfig.h: Explain ENABLE_CHANGEWORD.
7162 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted
7163 from code provided by Pete Chown]
7164 * m4.h: Add original_text field to u_t variant of union u.
7165 Declare TOKEN_DATA_FUNC macro.
7166 * builtin.c: Declare changeword.
7167 (m4_changeword): New function.
7168 * input.c: Include "regex.h", define variables with word regexps.
7169 (input_init): Initialize the word regexp.
7170 (set_word_regexp): New.
7171 (next_token): Declare local variables, use the previous code if
7172 default_word_regexp is true. Else, match using a new code. Save
7174 * macro.c (expand_token): Ship out original text if not a macro
7176 Reported by Krste Asanovic and Pete Chown.
7178 [These modifs all depend upon ENABLE_CHANGEWORD]
7179 * m4.h: Declare external user_word_regexp.
7180 * m4.c: Declare user_word_regexp, and initialize it from
7181 --word-regexp or -W, or NULL if not specified.
7182 * input.c: Use user_word_regexp if specified, instead of
7183 DEFAULT_WORD_REGEXP.
7185 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
7188 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.
7189 * checks/Makefile.in: Empty the suffix list.
7190 Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
7192 * m4.c: Declare nesting_limit and initialize it to 250.

7195 * m4.h: Declare nesting_limit as external.
7196 * macro.c (expand_macro): Stop execution whenever nesting limit
7198 Reported by Bengt Mertensson.

7201 Things like `eval(08)' used to return 0 with no diagnostic.
7203 * m4.h: Capitalize first letter of all macro arguments in
7206 * m4.c: Declare warning_status, initialize it to 0. Add new
7207 option -E, or --fatal-warnings, which sets warning_status to
7208 EXIT_FAILURE instead.
7209 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and
7210 EXIT_FAILURE if not otherwise done by header files.
7211 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE.
7212 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c,
7213 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first

7225 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
7226 also tested it on a Sun Sparc workstation running SunOS 4.x.
7228 * format.c (format): When not HAVE_EFGCVT, m4 was failing the
7229 49.format check, abusing a `union values' argument with sprintf
7230 without selecting the proper field. Now, save the formatting type
7231 first, delaying the fetch of the corresponding argument.
7232 Reported by Joseph E. Sacco and Tom Quinn.
7234 * format.c (format): Remove const from char *fmt declaration when
7235 not HAVE_EFGCVT, because a NUL may be forced into it.
7237 * m4.h: Declare atof() when not STDC_HEADERS.
7238 Reported by Joseph E. Sacco.
7240 * Regenerate configure using Autoconf 1.11, this corrects a

7258 substitute ${U}stackovf.o for STACKOVF.
7259 * acconfig.h: Declare USE_STACKOVF.
7260 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF).
7261 * m4.h: Declare setup_stackovf_trap().
7262 * m4.c: Call setup_stackovf_trap().
7263 * tests/stackovf_test.sh: New file.
7265 1994-04-13 François Pinard <pinard@iro.umontreal.ca>
7267 * checks/Makefile.in: Rename .all-stamp to stamp-checks.

7277 of `if ... else /* nothing */' for if macros.
7278 Reported by Jim Meyering.
7280 * builtin.c (m4_regexp): Reorganize the code for avoiding a
7281 warning from gcc about `repl' possibly used before defined.
7282 Reported by Jim Meyering.
7284 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>.
7285 Reported by Jim Meyering.
7287 1994-01-25 François Pinard <pinard@iro.umontreal.ca>
7289 * m4.h: Move the conditional definition of volatile after the
7290 inclusion of system files, because they may define it first.
7292 1994-01-04 François Pinard <pinard@iro.umontreal.ca>
7294 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
7295 get around a problem with Alpha make seeing a syntax error, there.
7296 Reported by Vern Paxson.
7298 1994-01-03 François Pinard <pinard@iro.umontreal.ca>
7300 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls.

7314 Use them in exit() and usage() calls.
7316 1993-11-27 François Pinard <pinard@iro.umontreal.ca>
7318 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and
7319 syserr() macro. Delete errref, add reference_error and M4ERROR.
7320 * m4.c: Replace errref, which was returning an input reference
7321 string, with reference_error, which prints it on standard error.
7322 * builtin.c, output.c: Use errno as second parameter to error,
7323 instead of using syserr() with %s.
7324 * *.c: Use M4ERROR instead of error: no more errref() with %s.
7325 Doing so, the program name appears after the input reference
7326 instead of before, which eases M-x next-error processing.
7328 1993-11-24 François Pinard <pinard@iro.umontreal.ca>
7330 * checks/get-them: Escape braces with backslashes in patterns,
7331 because HPUX-9.01 awk needs this.

7342 * *.c: Use error() systematically in place of all error macros,
7343 now that error() flushes stdout first. Make needed adjustments.
7345 * m4.h: Remove const in sys_errlist[] declaration, it creates
7346 conflicts on SGI and Alpha.
7347 Reported by Kaveh R. Ghazi.
7349 1993-11-20 François Pinard <pinard@iro.umontreal.ca>

7367 * input.c (input_init): Initialize quote and comment strings
7368 explicitely instead of calling set_quotes and set_comment: by
7369 doing so, we ensure we do not free uninitialized variables.

7372 expected is on the left and the obtained on the right.
7374 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR

7376 internal_error, add declaration for error_message_prefix.
7377 * m4.c: Delete m4error, warning, fatal and internal_error
7378 routines, add error_message_prefix routine.
7379 * *.c: Replace m4error routine calls with MESSAGE* macro calls,
7380 warning with WARNING*, fatal with FATAL* and internal_error with
7382 * Makefile.in (_m4.c): Do not adjust ansi2knr output for va_alist,
7383 this is not needed anymore.
7385 * m4.h: Declare extern FILE *debug. Add DEBUG_PRINT{1,3} and
7386 DEBUG_MESSAGE{,1,2} macros. Delete declarations for debug_print
7387 and debug_message, add declaration for debug_message_prefix.

7398 (trace_format): Use stdarg instead of varargs if __STDC__.
7400 * configure.in: Remove checks for vfprintf and _doprnt. These

7424 Reported by Joel Sherrill.
7426 * builtin.c (prefix_all_builtins): Instead of the table size, use
7427 the null entry at end for stopping the loop. It was overwritten.

7709 * Makefile.in: Remove references to version.h.
7711 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
7712 production, by using a simpler and more robust algorithm. This
7713 solves the problem of synclines sometimes written in the middle of
7714 an output line. Delete sync_line() and output_lines variable.
7715 * m4.h: Remove sync_line prototype and output_lines declaration.
7716 * input.c (next_char), output.c (shipout_text): Remove references
7718 * input.c (push_file, pop_file): Merely put the value -1 in
7719 output_current_line instead of calling sync_line, for delaying a
7720 single `#line NUM FILE' before next output line. Do not test
7721 for sync_output, because this is unnecessary clutter.
7722 * output.c (make_divertion, insert_divertion): Idem.
7723 * input.c: Rename must_advance_line to start_of_input_line, for
7726 * debug.c (trace_header): Select a new debug line format, which
7727 better complies with GNU standards for formatting error messages.
7728 With option `-dfl', M-x next-error might be used on the output.
7729 * m4.c (vmesg): Adjust format of error output to GNU standards.
7730 * m4.texinfo: Adjust examples for `make check' to work.
7732 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper
7733 case for enum debug_info constants, which were all lower case.
7735 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
7737 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
7738 collected patches. I tried a few times using newer regex.[ch], it
7739 mysteriously stopped aborting with this one. Insecure feeling...
7740 * lib/Makefile.in: Distribute regex.[ch].old, just in case!
7742 1992-12-18 François Pinard <pinard@iro.umontreal.ca>
7744 * m4.c: Change `--no-warnings' to `--silent'.
7745 Reported by David MacKenzie.
7747 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
7748 leave it off for now. See comment in m4.c for justification.
7749 Reported by David MacKenzie.
7751 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
7752 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
7754 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
7756 * Makefile.in: Ensure recursive cleaning is done before local
7757 cleaning for all clean goals.
7759 * builtin.c (ntoa): Ensure the value is always interpreted as a
7760 signed quantity, whatever the radix is.
7762 1992-11-18 Jim Meyering <meyering@idefix>
7764 * builtin.c, format.c, input.c: Split long lines.
7765 * m4.c: Use typedef macro_definition instead of struct
7767 * symtab.c: Use typedef symbol instead of struct symbol.
7769 1992-11-17 François Pinard <pinard@iro.umontreal.ca>
7771 * *.[ch]: Remove all trailing whitespace, in code and comments.
7773 * configure.in: Find some awk.
7774 * Makefile.in: Add $(AWK) to MDEFINES.
7775 * checks/Makefile.in: Transmit $(AWK) to get_them.
7776 * checks/get_them: Use $AWK instead of gawk. Add a close in the
7777 awk script when switching files, because without this, mawk runs
7778 out of file descriptors.
7780 1992-11-16 François Pinard <pinard@iro.umontreal.ca>
7782 * Makefile.in (realclean): Delete m4.info*.
7783 Reported by Jim Meyering.
7785 * Makefile.in: Adjust and link with checks/Makefile.
7786 * checks/Makefile.in: New.
7787 * configure.in: Output checks/Makefile.
7789 * checks/get_them: Have the dnl header of each test more
7790 recognizable by next-error, also use a better message.
7792 1992-11-16 Jim Meyering <meyering@idefix>
7794 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
7795 And use that only if __GNUC__ since we're using it's GCC-specific
7796 semantics that tell the compiler the associated function doesn't
7799 * builtin.c (substitute): Don't use character as an array index.
7800 (dumpdef_cmp): Make formal arguments `const void *' to avoid
7801 warnings with gcc -W -Wall on systems with qsort prototype.
7802 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
7805 * eval.c (most functions): Add parentheses to assignments used
7806 as truth values go avoid warnings from gcc -Wall.
7808 * input.c, m4.c, output.c, path.c, symtab.c: Declare static
7809 any functions that don't need external scope.
7811 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
7812 (many functions and arrays): Declare `const'.
7814 1992-11-15 François Pinard <pinard@iro.umontreal.ca>
7816 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
7817 removing the declaration from m4.h. Also rename false to FALSE
7820 * lib/Makefile.in (Makefile): New goal.
7822 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
7823 so heavily loaded. It gets more easily overridable, calling make.
7824 Reported by Jim Meyering.
7826 * Makefile.in (dist): Get .fname from the current directory name,
7827 instead of from version.h. I need updating many files manually,
7828 when the version changes, version.h is just one of them.
7830 1992-11-14 François Pinard <pinard@iro.umontreal.ca>
7832 * m4.h: Remove the tag `boolean' on the enum introducing typedef
7833 `boolean'. This tag conflicts with <sys/types.h> on SVR4.
7834 Reported by Tom McConnell.
7836 1992-11-13 François Pinard <pinard@iro.umontreal.ca>
7838 * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
7839 39.cleardiv, which were describing missing or spurious newlines.
7840 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
7841 do not depend on machine word size, `/bin/false' implementation,
7842 or `wc' output format. `make check' is more dependable, now.
7844 * checks/check_them: Summarize the failed tests by listing their
7845 name, at end. If none, issue `All checks successful'. Output
7846 `Checking' instead of `Input file:'.
7848 * checks/get_them, checks/check_them: Reindented.
7850 * Makefile.in (dist): chmod a+r before making the tar file.
7852 1992-11-12 François Pinard <pinard@iro.umontreal.ca>
7854 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
7856 * input.c (next_token): Reinitialize token_buttom just after using
7857 it as a watermark with obstack_free. Or else, a future token, big
7858 enough for triggering reallocation of the obstack chunk, could
7859 void the initialized value of token_buttom, later causing panic in
7860 obstack_free. Rename token_buttom to token_bottom everywhere.
7862 * m4.h: Before declaring errno, first include <errno.h> and
7863 ensure that it does not define errno.
7864 Reported by Richard Stallman.
7866 1992-11-11 François Pinard <pinard@iro.umontreal.ca>
7868 * builtin.c: Define and use DECLARE macro for builtins.
7870 * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one
7871 argument, this is a common idiom for introducing long comments.
7873 * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing
7874 arguments. The last argument was silently ignored.
7876 * m4.c (cmd_error): Add a missing semicolon before va_end().
7878 1992-11-10 François Pinard <pinard@iro.umontreal.ca>
7880 * Makefile.in: Now handle protoized sources. Define and use U.
7881 Compile and use ansi2knr with old compilers. Update DISTFILES.
7882 Add `aclocal.m4' to `configure' dependencies.
7883 * ansi2knr.c: New, from Ghostscript distribution.
7884 * configure.in: Define U through FP_PROTOTYPES for old compilers.
7885 Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T.
7886 * aclocal.m4: New, provide FP_PROTOTYPES.
7887 * m4.h: Conditionnaly protoized through Args, save for varags.
7888 * builtin.c: Protoized. Then:
7889 Include <sys/types.h> if size_t is not defined, before "regex.h".
7890 (m4_ifelse): Fetch built-in name properly for diagnostic.
7891 (m4_dumpdef): Remove wrong (char *) cast calling dump_symbol.
7892 (m4_regexp): Add const to `msg' declaration.
7893 (m4_patsubst): Add const to `msg' declaration.
7894 * debug.c: Protoized, save for varargs.
7895 * eval.c: Protoized.
7896 * format.c: Protoized.
7897 * input.c: Protoized.
7898 * m4.c: Protoized, save for varargs. Then:
7899 (xfree): Accept void * instead of char *.
7900 (xmalloc): Return void * instead of char *.
7901 (xrealloc): Accept and return void * instead of char *.
7902 * macro.c: Protoized.
7903 * output.c: Protoized.
7904 * path.c: Protoized. Then cast some (char *) over xmalloc's.
7905 * symtab.c: Protoized.
7907 1992-11-06 François Pinard <pinard@iro.umontreal.ca>
7909 * m4.texinfo: Remove directory from diagnostics in 30.include,
7910 51.eval, 56.errprint and 57.m4exit tests.
7912 * m4.h: Remove declarations for int or void system functions, they
7913 cause more conflicting trouble than they make good.
7915 * configure.in: Avoid configuration header file. Add some tests.
7916 * m4.h: Remove #include "config.h".
7917 * Makefile.in, lib/Makefile.in: Implement Autoconf interface.
7918 Then, rewritten for better compliance with GNU standards.
7920 1992-11-05 François Pinard <pinard@iro.umontreal.ca>
7922 * format.c (format): Avoid syntax error if not HAVE_EFGCVT,
7923 because of a misplaced #endif.
7925 * Many *.[hc] files: Correct intra-line spacing here and there,
7926 according to GNU indent 1.6 advice.
7928 * configure.in: New, using Autoconf 1.2.
7929 * m4.h: Reverse NO_MEMORY_H to NEED_MEMORY_H.
7930 * Delete old configure.in, configure, etc/configure.in,
7931 etc/configure, lib/configure.in, lib/configure and config/*.
7932 Reported by Jason Merrill.
7934 * symtab.c (hash): Change (char) NULL to '\0'.
7935 Reported by Jason Merrill.
7937 * Delete .vers, etc/newdist.sh, etc/newvers.sh and

7939 * version.h: De-automatize, force value in.
7941 * m4.c: Changes in order to use a newer getopt.h.
7942 Reported by David MacKenzie.
7944 * checks/: New name for examples/.
7945 * checks/get_them: New location for etc/get_examples.
7946 * checks/check_them: New location for etc/check_examples.
7947 * Makefile.in, checks/get_them, checks/check_them: Adjust.

7949 * Delete empty etc/.
7950 * examples/: New name for test/.
7952 1992-03-10 François Pinard <pinard@iro.umontreal.ca>
7954 * Makefile.in (check): Add m4 as dependency.
7956 * m4.c: Accept --no-warnings instead of --no_warnings, and
7957 --no-gnu-extensions instead of --no_gnu_extensions. Make the
7958 usage message more informative.
7959 Reported by David MacKenzie.

7978 Reported by Hal Peterson.
7980 * eval.c (exp_term): Have N^0 return 1.
7981 Reported by Michael Fetterman.
7983 * eval.c, input.c, m4.h: Remove last comma in enums.
7984 Reported by Mike Lijewski.
7986 * Transfer of maintenance duties from René to François.

7998 missing or superflous arguments to built-in macros.
8000 * Added default options via the M4OPTS environment variable.
8002 * The built-in format can now be configured to use sprintf as
8003 the formatting engine, for systems without [efg]cvt(3).
8005 * GNU library code is moved to the ./lib subdirectory; other
8006 utility files are now in ./etc.
8008 * Several minor bugs have been fixed.
8010 1991-07-26 René Seindal <seindal@diku.dk>

8013 François Pinard and Roland H. Pesch for providing me with reports.
8015 * The builtins incr and decr are now implemented without use of
8018 * The builtin indir is added, to allow for indirect macro calls
8019 (allows use of "illegal" macro names).
8021 * The debugging and tracing facilities has been enhanced
8022 considerably. See the manual for details.
8024 * The -tMACRO option is added, marks MACRO for tracing as soon
8027 * Builtins are traced after renaming iff they were before.
8029 * Named files can now be undiverted.
8031 * The -Nnum option can be used to increase the number of
8032 divertions available.
