dired in one buffer

dired in one buffer

[henning]

I would like dired to stay in the same buffer, e.g. when I go up one
directory I would like the present buffer to just clear and be replaced by
the content in the parent folder instead of opening a new buffer. If find it
quite annoying to have a stack of dired buffers open after looking around in
the directory tree... Does anyone know how to implement that? Or am I
missing something?

Cheers

You could bind a kill-buffer action to pressing/choosing .. or any  
other entry of type directory. Maybe dired-x allows things like this.

Could be you also miss that warm and very happy feeling of being glad  
that this particular directory is still in the list of buffers.

You could use dired-single

I have put this in my .emacs.
There's an other solution, type "a" instead of Enter to visit a directory (or a file).

 (defun dired-follow-file ()
  "In dired, visit the file or directory on this line.
If a directory is on the current line, replace the current Dired buffer with one containing the contents of the directory. Otherwise, invoke `dired-find-file' on the file."
  (interactive)
  (let ((filename (dired-get-filename)))
    (if (file-directory-p filename)
        (find-alternate-file filename)
      (dired-find-file))))

(defun dired-setup-follow-file ()
  (substitute-key-definition
   'dired-find-file 'dired-follow-file dired-mode-map)
  (substitute-key-definition
   'dired-advertised-find-file 'dired-follow-file dired-mode-map)) (add-hook 'dired-mode-hook 'dired-setup-follow-file)

Using standard dired, instead of entering a directory by pressing
"return" use "a" this replaces the dired buffer with the new directory.

Missing something. :-)

The functionality is mostly already present in emacs.  The function 
dired-find-alternate-file (normally assigned to the 'a' key in dired-
mode) replaces the current buffer (the dired buffer) with the 
file/directory that the cursor is on.  When the function exits the 
dired buffer containing the original directory has been killed and 
the active buffer contains the file/directory that was opened.  

Going down in the directory tree is intuitive.  Going up the 
directory tree requires that the cursor be on the '..' entry in the 
dired buffer.

If you are used to using the '^' to navigate up the directory tree 
then you will either need to retrain yourself or will need to do some 
elisp programing to attach the functionality to the '^' key.  I 
looked at the function dired-up-directory (in dired.el) which is 
associated with the '^' key, it does not look like it would be too 
difficult to create your own function based on it and assign it to 
the '^' key in dired mode.

Good luck,

This does exactly what I wanted. Although I from other posts now realise how
easy it is to live without this extension by just redefining "^" 

many thanks!

Indeed I removed dired-single.el now from my machine and use "a" in my
plain dired. I just didn't know this "a" until I read the answers of
the other people :)

    dired-find-alternate-file (normally assigned to the 'a' key in dired-
    mode) replaces the current buffer (the dired buffer) with the
    file/directory that the cursor is on.

Just thought I'd mention that you can also use `C-x C-v' to do this. Instead
of substituting the file or directory where the cursor is, it prompts you
for the file or directory name.

With a long directory listing (many files), when your cursor is not
necessarily near the file or directory you want to visit, it can be quicker
to use `C-x C-v', especially since you can use completion to provide the
name.

I would never bother to make an alternate-directory substitute command to
replace `^', for instance, because it is quick enough to do `C-x C-v' and
use, say, `M-DEL' (in the minibuffer) to remove the last directory
component. And I probably use `C-x C-v' more in Dired than anywhere else,
because although I often want several file buffers (visible or not), I don't
as often want multiple Dired buffers.

People use Emacs differently, but I find that my cursor in Dired is usually
not where I need it to be for this kind of thing (`a').

                  ^^^^^^^^^^^^^^ 

It escaped my imagination that `C-x C-v' also can be used in dired for
replacing the directory listing.  Thank you for mentioning this.

Yes, sometimes it helps to take a step back and try stuff you might assume
would not work (as they say, "think out of the box"). Emacs is full of
surprises like this - I wish I had a dollar for every time Emacs surprised
me with something that I wouldn't have thought possible.

The first time I saw Emacs tags in action, for example, it blew my mind.
That was many moon ago, but I had simply never thought of such a
possibility. Likewise, the idea that ordinary keys (e.g. `a', `b') would run
a command (`self-insert-command') just to get themselves inserted in a
buffer. Emacs is a wondrous toy, indeed.

The problem, of course, is that we quickly get into habits, and that can
work against exploration and discovery.
