[ shell buffer ] How not to split the current window?

[ shell buffer ] How not to split the current window?

[Philippe Chauvat]

Hello

Not new to emacs but pretty old to lisp and other emacs programming
stuffs. I am running the following emacs version.

GNU Emacs 25.2.2 (x86_64-pc-linux-gnu, GTK+ Version 3.22.17)
 of 2017-08-01, modified by Debian
Copyright (C) 2017 Free Software Foundation, Inc.

since a previous update, when using M-x shell, the shell opens in a new
buffer, splitting the window. Therefore, using C-x b don't send me back
to the original buffer but to a third one. This is really not useful for
me and I would be glad that M-x shell just open a new buffer, as it
would do for other matters, without splitting the existing one.

I read the doc, probably not enough, I read the mailing list archive,
and did not find anything. Any help would be welcome.

Cheers
Philippe

You could do:

  (add-hook 'shell-mode-hook 'delete-other-windows)

but that will only work the first time that "shell" buffer is created,
not if there is one already.

For the later case you may need to change the shell defun and add a call
to delete-other-windows after the pop-to-buffer (though I didn't test
it.)

Also you could make a key binding to (switch-to-buffer "*shell*").

It already exists.

C-x C-o (small oh) will move the cursor to the "other" window,
whatever that other window may be.  This can be invoked indefinitely
between the two open windows, moving the cursor back and forth between
the two, while leaving both windows open.

If you use C-x C-0 (zero), it will move the cursor to the "other"
window and CLOSE the window the cursor is currently in.  C-x C-1 (one)
will CLOSEY the other window while keeping current window open and the
cursor in the window the cursor is currently in.  Whew!

I don't know much about emacs, but I do know that!  ;)

These should be `C-x 0' and `C-x 1' respectively (no control modifer on
the digit).

`C-x C-0' is bound to an unrelated command (`text-scale-adjust') and
`C-x C-1' is unbound.

DOH!! 

Apparently, I know spit!  ;)

Hi Philippe,

AFAIU it sounds like you want an entry in `display-buffer-alist', e.g.

(add-to-list 'display-buffer-alist
             '("^\\*shell\\*" . (display-buffer-same-window)))


HTH,

Michael.

Hello all,

Thanks a lot for the answers you already sent. Actually, looking at
them, I would say, I'd like to have something like:
- M-x shell == open a shell and make the buffer the only one displayed.

Or,
M-x shell (redefined) = M-x shell (current version splitting the buffer)
+ C-x 1 (making the shell buffer the only one displayed).

Cheers
Philippe

I would still do that with `display-buffer-alist' (instead of advising
the function), e.g.

(add-to-list
 'display-buffer-alist
 `("^\\*shell\\*" .
   (,(defun my-display-shell-buffer-whole-frame (buffer alist)
       (prog1 (display-buffer-same-window buffer alist)
         (delete-other-windows))))))

Hi Michael,

It is just working fine. Thanks a lot. I wish my lisp skills were still
there :)

Best
