* -DVERSION for emacsclient

emacsclient.c includes

 #ifndef VERSION
 #define VERSION "unspecified"
 #endif

and, on non-Windows environments, it is compiled with -DVERSION="\"${version}\""

Is there any portable way to extract the version number from
lisp/version.el when executing lib-src/makefile (or when running
nt/configure.bat)?

The other option is hardcoding the version number in configure.bat or
lib-src/Makefile.w32-in, as it is hardcoded now on nt/emacs.rc. But
then admin/admin.el should have to be modified, shouldn't it?

You mean more portable than this:

  sed -n -e '/(defconst emacs-version/ s/^[^"]*\("[^"]*"\).*/\1/p' version.el

?

We could require Sed for the Windows build, and then do the above
(just replace single quotes with double quotes and escape-protect the
inner double quotes).  Or we could craft an equivalent command using
native Windows tools.

Gnuwin32 contains sed. I do not see much problem requiring it.

I don't really care much one way or the other, but it seems a bit
heavy-handed to require sed just to extract a version number for an
auxiliary tool like emacsclient.

That's what I was originally hoping for. Not very easy to do portably
all the way up from W95/98/98SE/Me, assuming we're still buildable on
these systems.

Hi Eli,

Wouldn't it be possible to make emacsclient depend on the Emacs binary
(if it isn't already) and use an Elisp script and "emacs -batch" to
put the value of emacs-version into emacsclient.c?

As an alternative, if you don't want to make that a strong dependency,
test if the Emacs binary is present and only call the Elisp script in
the common case that it has been made.


Just a thought,
benny

Well, it's buggy, for starters (errors out on some pretty innocent
regular expressions).  But beyond that, each additional program that
is not found on Windows by default is a potential nuisance, IMHO.

There's one other option: write a short C program that will run during
the build and extract the version string from version.el, and supply
that program as part of the Emacs distribution (in the nt/
subdirectory).

On balance, I think this is the best alternative.

That's trivial to do, but I don't understand why you don't favor just
hardcoding the version into nt/configure.bat or
lib-src/Makefile.w32-in and modifying admin/admin.el to update it...

That's what we currently do with nt/emacs.rc, man/emacs.texi,
lispref/elisp.texi and other files. And the rationale is the same:
for each given release it is a constant, it won't change during
compilation. There's no much point in building a program just to set
that constant.

Because someone needs to remember to update the hardcoded string each
time a new version is released.  Having that in admin.el is only a
band-aid, since someone needs to remember to run it prior to a
release.  That's a maintenance burden that we should avoid, I think.

However, given the amount of files we already handle in admin.el,
perhaps adding lib-src/makefile.w32-in to the list isn't a big deal.
Although I'd prefer that all those files except version.el were
handled like we do with -DVERSION in lib-src/Makefile.in.

Someone needs to remember pushing up the version anyway.

Releasing a version inevitably requires certain amount of
administrative steps, and running admin.el seems like the less of it.
All depends, I suppose, on whether the steps to be followed by the
release manager are documented.

I propose the following little patch, that uses the admin.el route and
is minimally disruptive. After the release we can change this to use
the method you suggest.

There's a difference between changing one file and changing half dozen
of them.

Are we at least in agreement that, in principle, anything that's done
automatically as part of preparing a release is better than the need
to do that manually?  Or are you saying that manual steps are not a
burden in any way?

> I propose the following little patch, that uses the admin.el route and

Thanks.  This is okay with me, but I'd prefer that the default value
of VERSION in lib-src/makefile.w32-in be UNKNOWN.  That way, if we
ever forget to run admin.el, we get the result shouting right in our
face.

Sure. But, as it stands now, the release manager does not change any
file. Even lisp/version.el is updated from admin/admin.el.

Of course. :)

No, I'm not saying that.

But VERSION is going to be UNKNOWN just the first time. Once the
release manager runs admin.el the first time (for example, when
releasing the 22.0.92 pretest), VERSION will have forever a version
string...

I can change the regexp to

  (rx (and "VERSION" (0+ space) "=" (0+ space)
           (submatch (or "UNKNOWN" (1+ (in "0-9."))))))

but it's a bit of complexity added for one time's sake.

Do you mean the modified makefile.w32-in are intended to be checked
into CVS?

Yes. How is that different from nt/emacs.rc or man/emacs.texi, which
are checked into CVS with the current version number?

Then it really doesn't matter what you put there, but please run
admin.el on it to produce the version string before you commit.
