Package: dictionaries-common
Version: 1.5.5
Severity: normal
File: /etc/emacs/site-start.d/50dictionaries-common.el
Usertags: emacs23-load-path-shadows
This package appears to provide old versions[0] of elisp libraries
that GNU Emacs 23 ships, and instructs GNU Emacs 23 to prefer these
old versions to its own.
Unfortunately, simply adding emacs23 to skip-emacs-flavors-list will
do the Wrong Thing, because you also provide a debian-ispell library,
which appears to provide functionality NOT already in GNU Emacs 23.
Ideas:
- change postinst so that SOME site-lisp directories get flyspell,
ispell and debian-ispell, and some only get debian-ispell.
- append (instead of prepending) to load-path, so that your
ispell/flyspell get lowest priority.
- keep your flyspell and ispell copies up to date, and hope that
doesn't break older emacsen (probably a bad idea).
PS: you should use "mode: emacs-lisp", not "mode: lisp" for elisp
files. That should be the default behaviour anyway, so I suggest
removing the local variables stanza entirely.
[0] The libraries aren't versioned, but the copyright is certainly
older.

Hi, and thanks for your detailed report,
Unlike it may look, flyspell.el and ispell.el shipped with Debian are
those of emacs23 before FSF emacs changed from using CVS to use bzr.
ispell.el is from 20090721 and flyspell.el is from 20090625. All further
relevant changes have been included in versions shipped by Debian, and even
more changes that were not shipped with emacs-23.2.
That means that in practice flyspell.el and ispell.el shipped with Debian
are more recent than those from emacs 23.2, and so I am closing this bug
report.
If you miss anything in Debian flyspell.el and ispell.el, please notify.
I am waiting until I have some time to regenerate Debian flyspell.el and
ispell.el after last versions from FSF emacs. I first want to integrate
upstream some of the Debian changes regarding XEmacs (I am part of FSF
Emacs upstream regarding flyspell.el and ispell.el) so, even if it does not
work with XEmacs out of the box, the number of Debian related changes to
make it work is smaller. Since FSF Emacs 23.3 branch is currently frozen I
am only committing to trunk changes that may go into the actual release.
Note that we need to modify pristine flyspell.el and ispell.el for better
integration with Debian spellchecking dictionaries and to try having a
consistent behavior from Emacs and XEmacs. Doing this in a less intrusive
way is also in my TODO list.

The problem is that Emacs 23.2 (not XEmacs) ships a subdirs.el file in
/usr/share/emacs/23.2/site-lisp and that makes original files (links) and
libraries to always be in the path. Debian emacsen-common policy requires
libs and elisp files to be put in that kind of dirs, and because of the
subdirs.el what you put there cannot be ignored. I complained about this
some time ago, but had no luck.
I have sometimes consdered breaking emacsen policy by using something like
a /usr/share/emacs/23.2/debian-site-lisp dir to make sure no subdirs.el
is acting there, so an extension can be disabled just from the /etc file.
Note that path is explicitly added from /etc file.

This in practice what we do, so we use single up-to-date flyspell.el and
ispell.el patched to work with Emacs 23, XEmacs (and currently even with
lenny Emacs21 and Emacs 22, something to be dropped soon). Patches must not
limit behavior neither in Emacs23 nor in the other flavors.

Thanks for the suggestion, this has been here for long time and I did not
even notice.
Again, if you miss something from bleeding edge FSF Emacs flyspell.el and
ispell.el, please let me know. Suggestions about the system are greatly
appreciated.
Thanks a lot for our feedback.
