From: Sergio Pokrovskij <sergio.pokrovskij <at> gmail.com> To: bug-gnu-emacs <at> gnu.org Subject: 24.3; Major mode spec in .dir-locals.el breaks dired Date: Wed, 14 May 2014 14:14:48 +0700
Given a .dir-locals.el file of the form:
--8<---------------cut here---------------start------------->8---
% ls -al /tmp/tst/
total 16
drwxrwxr-x 2 sergio sergio 4096 мая 14 12:01 .
drwxrwxrwt 17 root root 4096 мая 14 14:06 ..
-rw-rw-r-- 1 sergio sergio 44 мая 14 12:01 .dir-locals.el
-rw-rw-r-- 1 sergio sergio 4 мая 14 11:58 t.t
%
% cat /tmp/tst/.dir-locals.el
((nil . ((mode . c) (fill-column . 80))))
%
--8<---------------cut here---------------end--------------->8---
it works okay for the local files which are read with a path in the
command-line or with a find-file:
--8<---------------cut here---------------start------------->8---
% emacs -nw -Q /tmp/tst/t.t
--8<---------------cut here---------------end--------------->8---
The file is open in c-mode, the *Messages* contains:
--8<---------------cut here---------------start------------->8---
("emacs" "/tmp/tst/t.t")
For information about GNU Emacs and the GNU system, type C-h C-a.
Loading cc-langs...done
--8<---------------cut here---------------end--------------->8---
Yet it prevents the dired buffer for /tmp/tst/ to be displayed; a
"Wrong type argument: stringp, nil" message is issued.
This seems to occur for any major mode; I tried it for psgml-mode,
text-mode, c-mode.
It can be reproduced form batch or interactively. The batch version:
--8<---------------cut here---------------start------------->8---
% cat /tmp/tst/.dir-locals.el
((nil . ((mode . c) (fill-column . 80))))
%
% cat /tmp/ff.el
(find-file "/tmp/tst" t)
%
% emacs -Q -batch -l /tmp/ff.el
Loading cc-langs...
Wrong type argument: stringp, nil
%
--8<---------------cut here---------------end--------------->8---
Same for the interactive version:
--8<---------------cut here---------------start------------->8---
% emacs -nw -Q /tmp/tst/
--8<---------------cut here---------------end--------------->8---
*Messages* contains:
--8<---------------cut here---------------start------------->8---
("emacs" "/tmp/tst/")
For information about GNU Emacs and the GNU system, type C-h C-a.
