emacs: control tab buffer cycling, or stack buffer cycling, similar to alt-tab between windows

Question

I have consulted this resource: http://www.emacswiki.org/cgi-bin/wiki/ControlTABbufferCycling, and tried buffer-stack.el, which is useful, but I find the user e

elscreen does a little bit what you seek: http://wikemacs.org/index.php/Elscreen
You have to create screens (tabs) on demand and you can call M-x elscreen-select-and-goto to select a screen from a list in the minibuffer.

Fortunately it is already coupled with helm: helm-elscreen. That gives a good looking and handy choice list:

• fuzzy matching
• scrollable list
• choose actions (press TAB and choose "Change screen/Delete/Only").

However, you still have to create a screen manually (but I like it because I can organize sort of work areas -it is possible to isolate buffers per screen. A tab per buffer would be way too much + emacs creates many internal buffers so they can get on the way).

ps: helm-buffers-list is close to the interface you want for switching buffers, without tabs…

Try out this snippet:

(defun ctrltab ()
  "List buffers and give it focus"
  (interactive)
  (if (string= "*Buffer List*" (buffer-name))
      ;; Go to next line. Go to first line if end is reached.
      (progn
        (revert-buffer)
        (if (>= (line-number-at-pos)
                (count-lines (point-min) (point-max)))
            (goto-char (point-min))
          (forward-line)))
    (list-buffers)
    (switch-to-buffer "*Buffer List*")
    (delete-other-windows)
    (forward-line)))

(global-set-key [C-tab] 'ctrltab)

It's often inferior to ido-switch-buffer, but it does its job anyway.

Answer 3

I have been maintaining a personal copy of buffer-stack. It works really well -- to the extent that I haven't thought about it for years until recently when I had to fix a legacy workaround which caused a bug.

I will put my fork up on github when time allows. I'm not averse to adding some sort of index display although it does not matter much in my use-case -- helm is great to choose from a list of buffers.
