My guess is that the problem is that locate.el uses "/" without a
drive letter. I vaguely remember that it was hard to find a correct
behavior for expand-file-name when its second argument is "/", so
perhaps this bug is some side effect of what was decided long ago to
do in such cases.
Jason suggested (expand-file-name "/"). I _guess_ from your comments
above that this does not work either. I do not have access to a
computer running anything else but GNU/Linux or Solaris, so I can not
check. I guess that "what was decided long ago" refers to:
if (! STRINGP (default_directory))
{
#ifdef DOS_NT
/* "/" is not considered a root directory on DOS_NT, so using "/"
here causes an infinite recursion in, e.g., the following:
(let (default-directory)
(expand-file-name "a"))
To avoid this, we set default_directory to the root of the
current drive. */
extern char *emacs_root_dir (void);
default_directory = build_string (emacs_root_dir ());
#else
default_directory = build_string ("/");
#endif
}
Again, I don't think Emacs on Windows should have any buffer whose
default-directory is "/".
Yes, but I suppose you read the comment below, which Jason already
referred to. I am cc-ing Peter Breton, the author of locate.el.
;; Define a mode for locate
;; Default directory is set to "/" so that dired commands, which
;; expect to be in a tree, will work properly
(defun locate-mode ()
"Major mode for the `*Locate*' buffer made by \\[locate].
In that buffer, you can use almost all the usual dired bindings.
\\[locate-find-directory] visits the directory of the file on the current line.
\\{locate-mode-map}"
(kill-all-local-variables)
;; Avoid clobbering this variables
(make-local-variable 'dired-subdir-alist)
(use-local-map locate-mode-map)
(setq major-mode 'locate-mode
mode-name "Locate"
default-directory "/")
