Update copyright years automatically?

Update copyright years automatically?

[Lars Magne Ingebrigtsen]

Should we add `copyright-fix-years' to .dir-locals in gnus/lisp to have
that happen automatically, or is that too annoying?

If it is, what would be the most convenient way for me to have that
happen anyway?  :-)

(add-hook 'write-file-functions 'copyright-update)

I did

(setq before-save-hook
      (lambda ()
	(when (string-match "gnus/lisp/.*.el\\'" (buffer-file-name))
	  (copyright-update))))

to avoid having that happen other places.

It's kinda annoying that `copyright-update' queries me when saving, though.

Supposedly there may be an incompatible change planned in the future to
take away that single func in a hook feature
(http://debbugs.gnu.org/cgi-bin/bugreport.cgi?bug=5026)

I never found a clean way to express what should or shouldn't be
updated.

Maybe `copyright-query'.  I'd like it to show the buffer and highlight
the change it's about to make, like a query-replace, since occasionally
it's wrong.

What about changing it so that it's always right?  :-)

Ok, that may not be generally possible, but in, er, well-maintained
Emacs-included code like the gnus .el files, the format is very regular,
so just updating it without querying should be possible, I think.
Perhaps an optional parameter to `copyright-update'?

Oh, is it (setq copyright-query nil) though?

Ah, that should do the trick.  Thanks.

The only annoyance now is that it doesn't re-fill the paragraph after
inserting the new year.  Shouldn't it just do that unconditionally?

It could helpfully do that.  There seems to be a refill when it "fixes"
two-digit years, but not when just adding.

I suppose hanging indents like

 ;; Copyright (C) 1985, 1986, 1988, 1993, 1994, 1997, 1998, 2000, 2001,
 ;;   2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009
 ;;   Free Software Foundation, Inc.

might need a helping hand to create correctly when one-line becomes long
enough to turn into two-lines.

BTW, the GNU coding standards have been modified to allow compaction of
dates into a range (like 1997-2009) provided that the project has a note
in the README explaining what the range means.

`M-q' in these cases seem to do the right thing, so the copyright code
could just call that function.
