24.3; Dired does not insert subdirs when used with switch "--group-directories-first" |
|

If I remove the switch "--group-directories-first", then Bookmark Jump
works as expected. However, as long as the switch is put in,
sub-directories won't be inserted again.
I found out the problem in the function "dired-insert-old-subdirs" at line 1367 in dired.el. In this function, it has an or:
(defun dired-insert-old-subdirs (old-subdir-alist)
"Try to insert all subdirs that were displayed before.
Do so according to the former subdir alist OLD-SUBDIR-ALIST."
(or (string-match "R" dired-actual-switches)
(let (elt dir)
(while old-subdir-alist
(setq elt (car old-subdir-alist)
old-subdir-alist (cdr old-subdir-alist)
dir (car elt))
(condition-case ()
(progn
(dired-uncache dir)
(dired-insert-subdir dir))
(error nil))))))
The functional call to string-match:
(string-match "R" dired-actual-switches)
is the root cause. If dired-actual-switches is "-lha", then string-match
returns nil, and the code for inserting subdirs is going to be
executed. However, with dired-actual-switches is
"--group-directories-first -lha", then string-match returns 3, making
the or call returns true immediately and subdirs are never inserted.
"ls -R" recursively list directories. But matching it this way is
incorrect, since we have listing switches that contain character "R" in
it (i.e. --group-directories-first).
Hope that help.
Regards,
Tu.
