dns mode

dns mode

[Nachiket Gokhale]

It appears that I cannot save files with the extension "zone" e.g.
"foobar.zone" because emacs has loaded something called dns-mode by
default. How do I turn this thing off? What change do I have to make
to my .emacs.d/init.el file?

Thanks a lot,

Emacs associates file extensions and major modes by looking into
`auto-mode-alist` variable, you can clean all `.zone`-matching entries
from it if you don't want Emacs to turn on DNS mode when editing such files:

    (setq auto-mode-alist (delete '("\\.\\(soa\\|zone\\)\\'" . dns-mode) auto-mode-alist))
    (setq auto-mode-alist (delete '("\\.zone\\'" . zone-mode) auto-mode-alist))

You may get more information by reading section 27.1 of GNU Emacs manual
(«How Major Modes are Chosen»).

Oddly enough, my emacs (22.3) -Q has 2 entries for dns-mode in auto-mode-alist:

("\\.soa\\'" . dns-mode)
("\\.\\(soa\\|zone\\)\\'" . dns-mode)

So I would do something like:

(let ((auto-dns))
   (while (setq auto-dns (rassq 'dns-mode auto-mode-alist))
     (setq auto-mode-alist (delq auto-dns auto-mode-alist))))

And similarly for zone-mode.  This also has the advantage of working
regardless of the regexp used to match the file name.

A simpler solution is to not remove anything but add instead:

  (push '("\\.soa\\'" . my-mode) auto-mode-alist)

this will work regardless of the shape and number of entries in
auto-mode-alist.

Maybe it is a bug in dns-mode that there is no way to force a save?

Bye, Reiner.
