are properly templated, autoheader traces
AC_DEFINE/AC_DEFINE_UNQUOTED. Only literals can be traced, and
actually tracing non literals produces invalid autoheader input.
Hence, provide a means to trace calls to
AC_DEFINE/AC_DEFINE_UNQUOTED with literals.
* acgeneral.m4 (AC_DEFINE_TRACE, AC_DEFINE_TRACE_LITERAL): New
macros.
(AC_DEFINE, AC_DEFINE_UNQUOTED): Use AC_DEFINE_TRACE.
* autoheader.sh: Trace AC_DEFINE_TRACE_LITERAL, not
AC_DEFINE/AC_DEFINE_UNQUOTED.
* autoreconf.sh: Likewise.
* autoupdate.sh: Likewise.
* autoconf.sh: Change `exit' to `{ (exit 1); exit; }' after m4 and
awk commands to ensure exit state is in a defined state.
function calls.
Reported by John David Anglin.
* doc/autoconf.texi (Limitations of Usual Tools): Start the AWK
section.
* tests/tools.m4 (AWK portability): New test.
literal AWK program that performed the `oline' and quadrigraphs
substitution.
Fix its `oline' computation which was dead wrong when there are
empty lines (i.e., always).
Enhance it in order to look for and report unexpanded macro.
Don't let it pretend there are bugs in Autoconf (c:, the test
suite makes this scenario pretty unlikely as opposed to an actual
user bug.
Catch `m4_' too.
Remove the shell snippet which used to do this.
In fact, rename this option as -A, --autoconf-dir.
* autoconf.sh: Complain when -m, --macrodir is used.
Accept -A, --autoconf-dir.
Use $autoconf_dir instead of $AC_MACRODIR.
Adjust --help.
* autoheader.sh: Likewise.
* autoscan.sh: Likewise.
* autoupdate.sh: Likewise.
Use $optarg.
* autoreconf.sh: Likewise.
* doc/autoconf.texi: Adjust.
* tests: Adjust the test suite.
* autoheader.sh: Be more verbose, and always report your name in
verbose messages.
* autoconf.sh: Likewise.
* autoreconf.sh: Likewise.
(update.sh): Redirect ls's stderr to /dev/null.
* autoreconf.sh (update.sh): Use `ls -1dt' instead of `-lt'.
Use test instead of sed.
<automake>: If automake is used, always run it: it has its own
mechanism not to update if unneeded.
In fact, honor the most recent specification in the concatenation
of `syntax',$WARNINGS,<options> in that order.
Implement support for `none' and `noCATEGORY' so that the options
may override the previous choices.
Suggested by Didier Verna.
* acgeneral.m4 (_AC_WARNING_IFELSE): New macro.
(AC_WARNING_IFELSE): Use this macro to implement the new specs.
(AC_WARNING): The empty category must not be used, default to
`syntax'.
* doc/autoconf.texi (autoconf Invocation, Reporting Messages): Adjust.
* autoconf.sh: Adjust.
Use `optarg' to fetch the arguments of options.
Fix a bug in the handling of `--trace='.
* acgeneral.m4 (AC_CACHE_VAL): Typo: the macro was complaining iff
it shouldn't have.
`aclocal.m4' and that of the location Autoconf extensions.
(-M, --m4dir): New option.
(aclocal_flags): Do not use $localdir, but $m4dir.
(localdir_opt): Remove, since $autoconf, $autoheader already
include `-l $localdir'.
* autoreconf.sh: Don't run automake when the package is not using
it.
When checking whether autoheader should be rerun, don't ask
config.h to be newer than stamp-h and vice-versa.
Remove an unbalanced `fi'.
(alflags.sed): New sub sed program.
Compute the flags of aclocal from Makefile.am instead of
Makefile.in, it is unlikely that aclocal be used but not automake,
while it is convenient to be able to run autoreconf even if
automake was not run yet.
Use `autoconf --trace' to get the list of configuration headers.
* tests/base.m4 (m4_wrap, AC_REQUIRE, AC_SHELL_MKDIR_P): Use it.
* autoconf.sh: Properly handle the case where `$output' is `-'
(i.e., stdout).
Handle `-ofile', not only `-o file'.
$AUTOMAKE and $ACLOCAL.
Pass --verbose to the tools.
Avoid using plenty of variables, just append to existing
variables.
* doc/autoconf.texi: List options in the order --help, --version,
--verbose, --debug, and then specific options.
Reported by Mark Elbrecht.
* autoconf.sh <trace> (trace2m4.sed): Use `..*' instead of
`[^:][^:]*' to catch file names. The rest of regex is probably
precise enough to avoid incorrect parsing.
`yo-man-i-am-the-all-mighty-AVt0c0nF-eh-eh'. But when
`yo-man-i-am-the-all-mighty-AVt0h3Ad3R-eh-eh' and the other tools
want to trace, they might stupidly invoke the program named
`autoconf' instead. Pfff, stupid scripts :)
* Makefile.am (editsh): Transfer the names of the install
`autoconf' and `autoheader'.
* autoconf.sh: Add a missing period at the end of the comment
# Parse command line
Make sure to have a ChangeLog much longer than the patch.
* autoheader.sh: Use the right `autoconf'.
* autoupdate.sh: Likewise.
* autoreconf.sh: Likewise, and for `autoheader' too.
Simplify the handling of localdir and AC_MACRODIR.
* ifnames.sh: Formatting changes.
This is important if you want to redefine AC_INIT or some of its
sub macros (eeerk!), or if you want to use user defined macros
before AC_INIT.
Suggested by Didier Verna.
* acgeneral.m4 (_AC_INIT): Don't include `acsite.m4' and
`aclocal.m4'.
* autoconf.sh (run_m4, run_m4f): Do it.
