This email describes an issue that affects multiple software releases; I
have some patches, but they are not in a finalized state. Rather, I am
inviting some feedback to see if I am moving in the correct direction.
First, some background. The Austin Group approved XCU ERN 111 for
inclusion into the next revision of POSIX
(http://www.opengroup.org/austin/aardvark/latest/xcubug2.txt). I
originally filed ERN 111 because GNU M4 was not POSIX compliant (M4 1.4.x
treats $11 in a macro definition as the eleventh parameter, but POSIX 2001
requires it to treat it as the first parameter concatenated with 1), but I
did not have to perpetually maintain yet one more POSIXLY_CORRECT bit of
code in M4. The Austin Group agreed that the GNU extension of supporting
more than nine parameters is, in abstract, worth supporting, but asked for
a change in syntax:
Add to the Extended Description at line 22420:
"The string "${" produces unspecified behavior."
Add a paragraph to Rationale, after line 22607:
"Historic System V based behavior treated "${" in a macro definition as
two literal characters. However, this sequence is left unspecified so
that implementations may offer extensions such as ${11} meaning the
eleventh positional parameter. Macros can still be defined with
appropriate uses of nested quoting to result in a literal ${ in the output
after rescanning removes the nested quotes."
Now, for the explanation of the patches. I am hoping to release M4 1.4.9
(stable) and 1.9b (beta quality, with known bugs and dependent on
unreleased libtool, a precursor to a stable 2.0) in the next month.
With 1.9b, I would like to implement the resolution of XCU ERN 111. That
is, I plan on adding support for ${11}, so that the GNU extension of more
than 9 parameters is still alive (and in fact, I hope to borrow from shell
syntax for other extensions such as ${1-default}). I also plan on making
$11 obey POSIX semantics if POSIXLY_CORRECT, else obey 1.4.x semantics but
issue a warning that obsolete syntax was encountered. Then, after a
deprecation period, M4 2.1 could remove the POSIXLY_CORRECT check and
always treat $11 the way POSIX requires.
On the other hand, since 1.4.9 is stable, I can't break the existing
definition of $11, nor introduce ${11} as an extension. I can, however,
add warnings where we know the current syntax is in conflict with POSIX,
and that a future M4 release (1.9b or 2.0) will change semantics, so long
as those warnings don't interfere with existing M4 scripts.
Now for the problem - there are a number of existing M4 users that
currently have raw '${' in their macro definitions. If a user installs
autoconf 2.61 and then upgrades to M4 1.9b, things that used to work will
be silently broken because M4 will be trying to parse that as a parameter
expansion where it used to output literal characters. So we need a way to
help users detect these problems before they happen. Furthermore,
autom4te invokes 'm4 -E', which generally means if M4 prints a warning, it
will also exit immediately with a failure status.
My attached patches are a starting point. First, for M4 1.4.9, I added a
patch that adds a non-fatal warning, one that even 'm4 -E' won't choke on,
to see where the problem spots are, while still producing the same output
on stdout as 1.4.8:
$ m4-1.4.8a
define(`foo', `${1}')foo
- -> ${1}
=> m4:stdin:1: Warning: raw `${' in defn of foo will change semantics
Then I ran this patch with CVS automake and autoconf, and corrected all
the warnings that appeared until I could run the autoconf testsuite
without errors. These fixes to the autotools are critical before the next
release - if they are not fixed, then we still have the problem that a
user who installs autoconf 2.62, then upgrades to m4 1.9b, will have a
broken autoconf because the uses of raw ${ are interpreted differently.
Now for my questions. As it stands, the attached M4 patch is incomplete:
it makes the warning invariant, and always prints without changing exit
status, regardless of -E (make warnings fatal) or -Q (don't warn). That
is unacceptable, because of the number of warnings produced by autoconf
2.61 and automake 1.10, so I need some sort of compromise. I could add a
new option --warn-syntax to M4, but that seems a bit weak, since you would
then have to configure autoconf with M4='m4 --warn-syntax' to enable the
warning message to spot the potential pitfalls that would occur by
upgrading to M4 1.9b. I could also make M4 1.4.9 start parsing the
WARNINGS environment variable, and if it sees 'all' or 'syntax', then emit
the warning. This would be less likely to trip up ordinary users, but
slightly easier to exercise when testing a set of .m4 files for portability.
My other thought is that we can use m4sugar to our advantage. Basically,
until M4 2.0 is in wide use, and autoconf 3.0 is released which requires
M4 2.0 (and no longer supports 1.4.x), the syntax change in 1.9b means
that the use of raw ${ in autoconf macro definitions is no longer legal.
So would it be worth trying to change the m4sugar definition of m4_define
to something like the following:
define([m4_define], [regexp([$2], [\$][\{],
[m4_warning([syntax: raw [$]{ in [$1] will change semantics])])builtin(
[define], [$@])])
that lets autoconf 2.62 warn the user about the portability pitfall, even
if they are still using M4 1.4.8? Or even one step fancier:
define([m4_define], [regexp([$2], [\$][\{],
[m4_warning([syntax: raw [$]{ in [$1] will change semantics])])builtin(
[define], [$1], patsubst([[$2]], [\$\{], [[$]{]))])
Although the latter may lead to the occasional overquoted $ in output, at
least the warning points the user in the correct location to fix it.
Anyways, here are the patches in their current state:

@end example
+@node Quoting and Parameters
+@subsection
+
+When M4 encounters @samp{$} within a macro definition, followed
+immediately by a character it recognizes, it will perform M4 parameter
+expansion. This happens regardless of how many layers of quotes the
+parameter expansion is nested within, or even if it occurs in text that
+will be rescanned as a comment.
+
+@example
+define([none], [$1])
+@result{}
+define([one], [[$1]])
+@result{}
+define([two], [[[$1]]])
+@result{}
+define([comment], [# $1])
+@result{}
+define([active], [ACTIVE])
+@result{}
+none([active])
+@result{}ACTIVE
+one([active])
+@result{}active
+two([active])
+@result{}[active]
+comment([active])
+@result{}# active
+@end example
+
+On the other hand, since autoconf generates shell code, you often want
+to output shell variable expansion, rather than performing M4 parameter
+expansion. To do this, you must use M4 quoting to separate the @samp{$}
+from the next character in the definition of your macro. If the macro
+definition occurs in single-quoted text, then insert another level of
+quoting; if the usage is already inside a double-quoted string, then
+split it into concatenated strings.
+
+@example
+define([single], [a single-quoted $[]1 definition])
+@result{}
+define([double], [[a double-quoted $][1 definition]])
+@result{}
+single
+@result{}a single-quoted $1 definition
+double
+@result{}a double-quoted $1 definition
+@end example
+
+@acronym{POSIX} states that M4 implementations are free to use
+@samp{$@{} in macro definitions however they like. @acronym{GNU} M4
+1.4.x outputs those two characters literally, but @acronym{GNU} M4 2.0
+uses an extension modeled after shell variable expansion semantics.
+This is in part due to the fact that M4 1.4.x violates @acronym{POSIX}
+by treating @samp{$11} as the eleventh parameter, rather than the first
+parameter concatenated with the string @samp{1}. To comply with
+@acronym{POSIX}, M4 2.0 prefers @samp{$@{11@}} rather than @samp{$11}
+when referring to the eleventh parameter.
+
+Therefore, for your autoconf script to be portable, regardless of
+whether the user has M4 1.4.x or 2.0 installed, you must use M4 quoting
+to separate @samp{$} from any of these characters --- @samp{@{},
+@samp{0}@dots{}@samp{9}, @samp{*}, or @samp{@@} --- if you want the pair
+to make it to the output.

With this in mind, we can explore the cases where macros invoke
