I don't see it here, I still see the behavior you are used to. Please try in "emacs -Q". If the problem disappears there, then the culprit is one of your customizations, or maybe some init file brought by whoever packaged Emacs 24 on your platform. ^ permalink raw reply [flat|nested] 9+ messages in thread

I reviewed my muscle memory again :-) The change in behavior is when there are already two buffers being shown, with different files. So, with two files, a and b: $ emacs -Q a b I get just "b" displayed. ^X^B^Xo, cursor down, Enter. I get the "b" file in the top window, "a" file in the bottom window, with the cursor in the "a" file's window. ^X^B The buffer window now replaces the "a" file, where the cursor was, and the cursor now winds up in the buffer list window. That's the different behavior than what I'm used to. Now, if instead of doing ^X^B at this point, I press ^Xo, moving the cursor back to the "b" file's window, then ^X^B still opens the list buffer in the "a" file's window (also). So, maybe the change in behavior is that list-buffers' window is "sticky", and it tries to open the buffer window in the same window it was previously shown in, apparently. If that window is showing another file buffer, even if the cursor is still in that file buffer the buffer list window still gets opened there, replacing the buffer the cursor was in. So, depending on window history, ^X^B ends up either opening the buffer list window in some other window, than the one the cursor is currently in, or the same window where the cursor is. I'm pretty sure that in earlier versions of emacs, ^X^B never opened the list buffer in the same window the cursor was, at the time the list-buffers command was executed. And that's where my muscle memory is failing me now. I'm used to having multiple windows open; and with the cursor in one of them, ^X^B opening the buffer in some other window, and then typing ^Xo to jump into the buffer list window. Now, depending on where the buffer-list window was previously shown, it will now open in the same window with the cursor, and I realize belatedly, after I already jumped somewhere else with ^Xo.

Your explanation is correct. The behavior is intended as a feature but inherently breaks the behavior of `pop-to-buffer', especially when used interactively. I intend to fix this soonish for Emacs 25 and also post a simple workaround you can use for Emacs 24.4. Kindly add your observations to this thread http://debbugs.gnu.org/cgi/bugreport.cgi?bug=20206 so we can discuss the solution there. And please use our conventional notation for key bindings. That is, write C-x C-b C-x o instead of ^X^B^Xo and RET instead of ENTER. Thanks, martin ^ permalink raw reply [flat|nested] 9+ messages in thread

I think the following piece of magic will do what Sam wanted: (setq display-buffer-alist '(("\\*Buffer List\\*" . (display-buffer-pop-up-window '((inhibit-same-window . t)))))) If this is desired for all buffers, the regexp should be changed to something that matches any buffer name. ^ permalink raw reply [flat|nested] 9+ messages in thread

What Eli meant was more or less (setq display-buffer-alist '(("\\*Buffer List\\*" nil (inhibit-same-window . t)))) But this is still problematic because it will disallow reusing a window that already shows the buffer list. Even if you explicitly ask for it as in (setq display-buffer-alist '(("\\*Buffer List\\*" display-buffer-reuse-window (inhibit-same-window . t)))) it won't work when you do C-x C-b in the selected window and that window shows the buffer list already. You might call it a feature but when `display-buffer' is used programmatically, popping up or using another window to show a buffer already shown elsewhere is usually considered a nuisance. So something better is needed here. martin ^ permalink raw reply [flat|nested] 9+ messages in thread

I did test it, and it did work for me. So something else is at work here. In any way, feel free to explore other possible customizations along the same lines, you will surely find what you want. ^ permalink raw reply [flat|nested] 9+ messages in thread

Yes, the default behavior changed, so you need to customize display-buffer's strategy to get what you want. Since Martin requested to continue this discussion on the bug tracker, I will reply there with a recipe that I think will do what you want. ^ permalink raw reply [flat|nested] 9+ messages in thread
