问题:

How do I close all but the current buffer in Emacs? Similar to "Close other tabs" feature in modern web browsers?

回答1:

For a more manual approach, you can list all buffers with C-x C-b, mark buffers in the list for deletion with d, and then use x to remove them.

I also recommend replacing list-buffers with the more advanced ibuffer: (global-set-key (kbd "C-x C-b") 'ibuffer). The above will work with ibuffer, but you could also do this:

m (mark the buffer you want to keep)
t (toggle marks)
D (kill all marked buffers)

I also use this snippet from the Emacs Wiki, which would further streamline this manual approach:

;; Ensure ibuffer opens with point at the current buffer's entry.
(defadvice ibuffer
  (around ibuffer-point-to-most-recent) ()
  "Open ibuffer with cursor pointed to most recent buffer name."
  (let ((recent-buffer-name (buffer-name)))
    ad-do-it
    (ibuffer-jump-to-buffer recent-buffer-name)))
(ad-activate 'ibuffer)

From EmacsWiki: Killing Buffers:

(defun kill-other-buffers ()
    "Kill all other buffers."
    (interactive)
    (mapc 'kill-buffer 
          (delq (current-buffer) 
                (remove-if-not 'buffer-file-name (buffer-list)))))

Edit: updated with feedback from Gilles

There isn't a way directly in emacs to do this.

You could write a function to do this. The following will close all the buffers:

(defun close-all-buffers ()
  (interactive)
  (mapc 'kill-buffer (buffer-list)))

There is a built in command m-x kill-some-buffers (I'm using 24.3.50) In my nextstep gui (not tried in a terminal but sure it's similar) you can then approve which buffers to kill.

回答5:

 (defun only-current-buffer () 
   (interactive)
   (let ((tobe-killed (cdr (buffer-list (current-buffer)))))
     (while tobe-killed
       (kill-buffer (car tobe-killed))
       (setq tobe-killed (cdr tobe-killed)))))

It works as you expected.

And after reading @Starkey's answer, I think this will be better:

(defun only-current-buffer () 
  (interactive)                                                                   
    (mapc 'kill-buffer (cdr (buffer-list (current-buffer)))))

(buffer-list (current-buffer)) will return a list that contains all the existing buffers, with the current buffer at the head of the list.

This is my first answer on StackOverflow. Hope it helps :)

I found this solution to be the simplest one. This deletes every buffer except the current one. You have to add this code to your .emacs file

(defun kill-other-buffers ()
      "Kill all other buffers."
      (interactive)
      (mapc 'kill-buffer (delq (current-buffer) (buffer-list))))

Of course, then you use it with M-x kill-other-buffers RET or you paste the following code in the .emacs file too and then just press C-xC-b

(global-set-key (kbd "C-x C-b") 'kill-other-buffers)

I've use crux-kill-other-buffers for some months.

But I want dired buffers get deleted too. @Euge's and @wenjun.yan's answers solve this. But it will delete special buffers (e.g *git-credential-cache--daemon*, *scratch*, helm operation, and etc). So I came up with this (current) solution.

(defun aza-kill-other-buffers ()
  "Kill all buffers but current buffer and special buffers"
  (interactive)
  (dolist (buffer (delq (current-buffer) (buffer-list)))
    (let ((name (buffer-name buffer)))
      (when (and name (not (string-equal name ""))
             (/= (aref name 0) ?\s)
             (string-match "^[^\*]" name))
        (funcall 'kill-buffer buffer)))))

Inspired from kill-matching-buffers. You can add more condition on other buffer-name to exclude, if you want to.

Hope it helps :)

You can like this one as well - kill all buffers except current one, *Messages* and *scratch* (which are handy to have, I call them "toolkit"), close redundant windows as well, living you which one window which current buffer.

(defun my/kill-all-buffers-except-toolbox ()
  "Kill all buffers except current one and toolkit (*Messages*, *scratch*). Close other windows."
  (interactive)
  (mapc 'kill-buffer (remove-if
                       (lambda (x)
                         (or
                           (string-equal (buffer-name) (buffer-name x))
                           (string-equal "*Messages*" (buffer-name x))
                           (string-equal "*scratch*" (buffer-name x))))
                       (buffer-list)))
  (delete-other-windows))
