emacs list-buffers behavior

Question

In GNU emacs, every time I hit Ctrl-x Ctrl-b to see all of my buffers, the window is split to show the buffer list, or if I have my window already split in 2 (for instance, I will have a shell running in the lower window), the buffer list appears in the other window.

My desired behavior is for the buffer list to appear in my active window so that I can select the buffer I want and continue to working in the same window, rather than having to Ctrl-x Ctrl-o to the other buffer, selecting the buffer (with enter) and editing that buffer in the other window... I've googled for it but it doesn't seem to be a common desire? I wonder if anyone has an elispy (or other) solution?

Answer 1

not exactly a solution, but ido-mode provides a different and powerful way to interact with buffers. C-x b will then show a list of all the open buffers, and the one you select will open in the current window.

Answer 2

Another not-what-you-asked-for solution: don't select the desired buffer with the mouse, rather finish typing its name (use tab-completion to reduce keystrokes and increase accuracy), then hit return. The buffer list will disappear, and the new file will be open in the previously active window.

Answer 3

Not sure where I got this but:

;;; Faster buffer switching
(global-set-key [(C tab)] 'buffer-menu)

This makes Ctrl-Tab display all buffers in the current window. You can then navigate to a buffer and hit Enter to visit it.

Answer 4

You might want to rebind C-x C-b to invoke buffer-menu rather than list-buffers.

(global-set-key "\C-x\C-b" 'buffer-menu)

Answer 5

If you like the original buffer list (as opposed to the 'buffer-menu solution proposed by others), you can use this:

(global-set-key (kbd "C-x C-b") 'my-list-buffers)
(defun my-list-buffers (&optional files-only)
  "Display a list of names of existing buffers.
The list is displayed in a buffer named `*Buffer List*'.
Note that buffers with names starting with spaces are omitted.
Non-null optional arg FILES-ONLY means mention only file buffers.

For more information, see the function `buffer-menu'."
  (interactive "P")
  (switch-to-buffer (list-buffers-noselect files-only)))

Which is the same function as before, only in the current window.

Answer 6

Just customize the variable same-window-regexps. display-buffer will display any buffer whose name matches a regexp there in the currently-selected window.

(You will want to add "[*]Buffer List".)

Answer 7

I highly recommend bs.el from http://www.geekware.de/software/emacs/ Install it and:

(require 'bs)
(add-hook 'bs-mode-hook 'turn-on-font-lock)
(global-set-key "\C-x\C-b" 'bs-show)

It manages buffers and window configuration in the right way, so everything requires minimum number of keystrokes.

Answer 8

Try to add

(ido-mode 1)

to your .emacs, and enjoy the result :)

Answer 9

Does anybody know how to make the buffer list disappear again?
