Oh, that. Like Joost Kremers mentioned earlier today, and like I posted
earlier, that issue is solved by adding a single blank line to the
header. Here's what I wrote earlier:

--8<--cut here-(start)------------------------------------------- >8
;; Package-Requires: ((emacs "26.1"))
;;   (emacs "24.1") for: split-window-right, window-normalize-frame

Should be:

;; Package-Requires: ((emacs "26.1"))
;;
;;   (emacs "24.1") for: split-window-right, window-normalize-frame
--8<--cut here-(end)--------------------------------------------- >8

Once you make that change, you can install the package in the way you
are accustomed. That change was uploaded to github hours ago, when I
posted the original fix.

Any way you prefer.

You can use github without javascript, directly from emacs, to report
issues. The packages for that are: magit and forge. Maybe also ghub?

I've downloaded an played the video several times at slow speed, but
can't figure out what keys you're pressing and what is going on.

1] There exists a debian package called 'screenkey' which you can use in
   conjunction with screencasts. Any time you press a key, the program
   display that key as part of your screencast. Other similar packages
   probably exist for other operating systems.

2] Can you describe the steps you took before your 'console broke'?

3] Your video shows you recovered. How did you do that?

4] I'm not familiar with EXWM. Is that the starting point of the video?

> And I have used emacsclient.

Shouldn't be an issue. I always use emacsclient, and tested the package
from both a standalone emacs and a server/client instance.

I didn't see that in your video. Your video shows a buffer labeled
*scratch* in a frame labeled F6.

Mine does many more things than the built-in. See the documentation.

You can change the list for metadata commands available on your system
(it's a defcustom: diredc-show-more-file-info-list). Let me know details
and I can figure out how to include them. What do you get when you
perform "M-: system-type"?

Yes. The differences include the persistence of the bookmark over emacs
sessions and the ability to use the defcustom interface to manage the
bookmark list.

Yes. It is expected. It is giving you several useful dired-related data
in shell variables. See the documentation.

It uses the default as set in defcustom variable `diredc-shell-default'.

You didn't read any of the documentation, did you? The navigation
between buffers is using <TAB>. That said, C-x o should work fine. I
can't reproduce a problem with it. Please send more details.

And I don't understand. Probably good idea for another screencast, if
you want. Consider using the screenkey program or similar so viewers can
see what it is you're doing.

Then you probably didn't turn it off or exit it. I would need some more
details in order to reproduce your scenario.

That means you have two windows showing the same dired or diredc buffer.

Not on same line as what? POINT?

Again, without details I don't know where to start. In this case, can
you provide a backtrace?

Yes. That is expected behavior. On the one hand, we want to prevent
people from making a mess if what they are trying to do is exit diredc;
on the other hand, we want to give them the option of performing
quit-window and making a mess if they insist. diredc-exit performs an
elegant and complete clean-up, while quit-window just closes a window
and leave behind the buffer to come back to haunt you. What is a bug is
that the actual keybinding wasn't being displayed. I just now pushed a
commit to fix that. You can make the change manually by altering line
2077 from:

  (message "Use \\[diredc-exit] for diredc-exit, or M-x quit-window for the 
emacs primitive."))

to

  (message "Use %s for diredc-exit, or M-x quit-window for the emacs primitive."
    (key-description (where-is-internal 'diredc-exit diredc-mode-map t))))


Keep in mind that one of your options is "M-x diredc-recover", which
restores your buffer and window configuration if you unintentionally or
intention mess it up.

So. A lot of feedback, which is good. If you can provide more details for
the items of trouble you're reporting, I can try to address them.
