I asked for some help on emacs.stackexchange.com to implement these new approaches, and used the answers by @Drew, @Tobias and @Andreas Röhler. Citations to their answers are included in the draft/proof-concept patch. I would need some help regarding how to update the dired-directory variable when deleting a file in a regular dired-mode buffer, and I have added a FIXME notation in the likely spot of `dired.el` -- the approach would be similar to renaming a file (already implemented in the attached draft patch), but is a bit more complicated due to potential recursive deletions. The file-name-nondirectory components in wdired-mode now have read-only attributes so that a user no longer erroneously believes that he/she can modify them, and only latter see an error message when trying to commit the changes: file-error Renaming No such file or directory .... I have only done some basic renaming of files and directories in wdired mode using both `find-name-dired` and `dired-list-files-folders' to populate the dired- buffer. I did not spend any time implementing hash-tables to speed up the modification of the dired-directory variable, as that would likely involve modifying a few or more aspects of dired-mode.

I applied the new diff and was able to successfully use the second option with `find-dired`. As to the first option, however, I would need to spend time learning about zsh, fish and em-ls. So, that exploration would need to wait for a rainy day. Oh, by the way, please consider adding a `nil` to the end of `(defvar wdired-old-marks)` so that the user does not experience this: funcall-interactively: Symbol’s value as variable is void: wdired-old-marks In my spare time, I will most likely continue implementing functionality for wdired playing nice with: (dired (directory-files-recursively "/path/to/directory" "" 'include-directories)) That will entail: (1) placing read-only text properties over areas that cannot be changed; (2) when I modify a directory, I will need to propagate that change throughout the applicable entries of `dired-directory'; (3) I will consider implementing a hash-table approach with `dired-directory` entries for increased speed.

Thank you for your report Keith!
You are right, it looks annoying.
Though I haven't arrived with an ideal solution, following
are two ways how I would try to perform a similar task.
I)
If you are lucky and "sh" points to a shell that
supports globstar (zsh, fish), or if you are using dired
via `em-ls', then you can do:
M-x dired /path/to/directory/**/* RET
;; Now both, wdired and `dired-do-rename' works fine.
[If you are using bash or ksh, that support globstar but
disable it by default, then you might be interestd in my
proposal in Bug#31495: it gives the chance to enable such
feature on dired via an user option.]
II)
Another way could be to use a command of the `find-dired' family:
M-x find-name-dired /path/to/directory/ RET * RET
;; I just noticed that wdired resets `revert-buffer-function' also for
;; these dired buffers. IMO it shouldn't, so I would propose
;; something like this:

I occasionally have the need to rename files and directories that are rec=
ursively located. I create a dired-mode buffer as follows:
(dired (directory-files-recursively "/path/to/directory" "" 'include-=
directories))
Wdired: The first problem is that `wdired-get-filename' needs to be modi=
fied so that it handles absolute paths differently than relative filename=
s. Here is an example that works -- using `file-name-absolute-p`:
(defun wdired-get-filename (&optional no-dir old)
"Return the filename at line.
Similar to `dired-get-filename' but it doesn't rely on regexps. It
relies on WDired buffer's properties. Optional arg NO-DIR with value
non-nil means don't include directory. Optional arg OLD with value
non-nil means return old filename."
;; FIXME: Use dired-get-filename's new properties.
(let (beg end file)
(save-excursion
(setq end (line-end-position))
(beginning-of-line)
(setq beg (next-single-property-change (point) 'old-name nil end))
(unless (eq beg end)
(if old
(setq file (get-text-property beg 'old-name))
;; In the following form changed `(1+ beg)' to `beg' so that
;; the filename end is found even when the filename is empty.
;; Fixes error and spurious newlines when marking files for
;; deletion.
(if (=3D (point-at-eol) (point-max))
(setq end (point-max)) ;; fix for @lawlist eliminating final new li=
ne at eob.
(setq end (next-single-property-change beg 'end-name)))
(setq file (buffer-substring-no-properties (1+ beg) end)))
(and file (setq file (wdired-normalize-filename file))))
(if (or no-dir old)
file
(cond
;;; When FILE is relative, concatenate default-directory to beg=
inning.
((and file
(> (length file) 0)
(not (file-name-absolute-p file))
(concat (dired-current-directory) file)))
;;; When FILE is absolute, no need to concatenate the default-d=
irectory.
((and file
(> (length file) 0)
(file-name-absolute-p file)
file)))))))
Dired: The second problem is a dired-mode problem in that the `dired-dir=
ectory' variable is not updated when renaming a file. I haven't tested d=
eleting a file, but that probably suffers the same problem. Absent updat=
ing the `dired-directory` with the renamed filename, the `revert-buffer` =
will encounter errors because `ls` or `gls` will try to find files that n=
o longer exist, and that errors will be inserted into the dired- buffer. =
A quick solution for renaming the file is to modify `dired-rename-file` =
as follows:
;;; (setq mylist '("apple" "pear" "peach" "nectarine" "watermelon"))
;;; (ar-replace--in-list "apple" "cherry" mylist)
;;; Written by @Andreas R=C3=B6hler: https://emacs.stackexchange.com/a/4=
1631/2287
(defun ar-replace--in-list (elem replacement list)
"Expects a LIST of strings.
ELEM: element to replace by arg REPLACEMENT"
(let (newlist)
(dolist (ele list)
(if (string=3D ele elem)
(push replacement newlist)
(push ele newlist)))
(nreverse newlist)))
(defun dired-rename-file (file newname ok-if-already-exists)
(dired-handle-overwrite newname)
(rename-file file newname ok-if-already-exists) ; error is caught in -c=
reate-files
;;; Update the `dired-directory'
(when (and (listp dired-directory)
(member file dired-directory))
(setq dired-directory
(ar-replace--in-list file newname dired-directory)))
;; Silently rename the visited file of any buffer visiting this file.
(and (get-file-buffer file)
(with-current-buffer (get-file-buffer file)
(set-visited-file-name newname nil t)))
(dired-remove-file file)
;; See if it's an inserted subdir, and rename that, too.
(dired-rename-subdir file newname))
However, this is understandably slow if there are a lot of files. Perhap=
s a hash-table system would be better suited to keep track of files and d=
irectories instead of just a plain old list with file/directory names.
I haven't yet figured out the best approach to modify a wdired-mode buffe=
r that has a combination of directories and files. Presumably some porti=
on of the absolute filename/directory-name will need read-only attributes=
.... But, that is as far as my thinking has gone on this issue.
There may be many other situations that I haven't thought of because I've=
never used all of the features of dired-mode and/or wdired-mode.
