renaming current file and buffer

renaming current file and buffer

[Dieter Wilhelm]

Hi

Every so often I'm working on a file whose name I've not chosen
appropriately.  So far I couldn't find an elegant way in Emacs to
rename the file and the buffer at the same time.  I found the function
definitions below in the net, which serve my needs perfectly, but I'm
wondering whether I've overlooked something equally fitting from standard
emacs packages? What are you doing in this situation? Yes I know:
Thinking in advance, but ...

(defun rename-file-and-buffer (new-name)
  "Renames both current buffer and file it's visiting to NEW-NAME."
  (interactive "sNew name: ")
  (let ((name (buffer-name))
	(filename (buffer-file-name)))
    (if (not filename)
	(message "Buffer '%s' is not visiting a file!" name)
      (if (get-buffer new-name)
	  (message "A buffer named '%s' already exists!" new-name)
	(progn
	  (rename-file name new-name 1)
	  (rename-buffer new-name)
	  (set-visited-file-name new-name)
	  (set-buffer-modified-p nil))))))

(defun move-file-and-buffer (dir)
  "Moves both current buffer and file it's visiting to DIR."
  (interactive "DNew directory: ")
  (let* ((name (buffer-name))
	 (filename (buffer-file-name))
	 (dir
	  (if (string-match dir "\\(?:/\\|\\\\)$")
	      (substring dir 0 -1) dir))
	 (newname (concat dir "/" name)))

    (if (not filename)
	(message "Buffer '%s' is not visiting a file!" name)
      (progn
	(copy-file filename newname 1)
	(delete-file filename)
	(set-visited-file-name newname)
	(set-buffer-modified-p nil)
	t))))

Doesn't C-x C-w (`write-file') work for you?
It does have the side effect of saving the buffer at that time, sorry if
that's not what you want.

Agreed, write-file gives me the opportunity for choosing another name
(with the corresponding buffer name).  But then I'd have to kill the badly
named file in a second step (e.g. in a dired buffer) since the old,
now redundant file remains on the file system.

Thank you for your reply.  I'm new to newsgroups, may I ask why you've
written to my email address directly and copied your message to
`help-gnu-emacs@gnu.org', isn't it usual posting directly (and solely)
to the newsgroup?

I now remember how I handle this: I rename in dired-mode the file I  
am editing (having it saved before). The buffer name follows this  
change after some time.

Knowing the behaviour of `rename-file' (not changing the buffer name)
I was somehow prejudiced against testing this possibility with
dired. But it actually works, thanks a lot for this hint!

With the standard dired it's a tad slow albeit.  It means getting into
dired (C-x 4 d, lest I don't forget the filename), then looking for
the file (possibly searching with C-s).  This might, just might
justify the hassle of using a home-made function.  But with the
dired-x package - I just discovered - its working like a charm.  Just
typing C-x C-j in the respective buffer is getting one into a dired
buffer with point already at the corresponding file! Then R NEW-NAME
RET RET and here we are again.

Great stuff

Just type C-x d in the buffer whose file name you want to rename. It  
will position the cursor in dired on that file!

1/ The list has a bidirectional gateway with the newsgroup, or so I
assumed.  Has my reply not appeared in the newsgroup?  I have stopped
using newsgroups at all because I can't find a quality free server in my
area.  My ISP has just stopped offering NNTP access altogether (not that
I used it because it was crappy like most of them).

It's not working for me when I previously have opened the file with
C-x C-f.  Only when the file at some stage have had the focus in dired

Could be this customisation helps:

'(dired-dwim-target t)

What does that do?


dired-dwim-target-directory is a compiled Lisp function in `dired-aux'.
(dired-dwim-target-directory)

Not documented.

Is this better?

	dired-dwim-target is a variable defined in `dired.el'.
	Its value is t
	
	Documentation:
	*If non-nil, Dired tries to guess a default target directory.
	This means: if there is a dired buffer displayed in the next window,
	use its current subdir, instead of the current subdir of this dired  
buffer.
	
	The target is used in the prompt for file copy, rename etc.
	
	You can customize this variable.


'dwim' stands for 'do what I mean.'

No, unfortunately not.
the only way I got the intended effect is with this extension from dired-x
     (define-key global-map "\C-x\C-j" 'dired-jump)

But this is also a great alleviation, reminds me a bit of the midnight
commander!

Thanks a lot
