Automatically move cursor to end of shell-mode buffer on M-p / M-n

Automatically move cursor to end of shell-mode buffer on M-p / M-n

[Andrew Pennebaker]

As a shell user, I want shell-mode M-p / M-n to automatically move my
cursor to the shell prompt, so that shell-mode behaves more intuitively.

Currently, attempting to use M-p / M-n when the cursor is not at the
prompt, results in a warning message. I think we can make shell-mode behave
more intuitively.

I have a workaround for this in my .emacs:

;; Automatically move cursor to prompt on shell up/down
(add-hook 'shell-mode-hook
          (lambda ()
            (define-key comint-mode-map (kbd "M-p")
              (lambda (arg)
                (interactive "*p")
                (goto-char (point-max))
                (comint-previous-input arg)))
            (define-key comint-mode-map (kbd "M-n")
              (lambda (arg)
                (interactive "*p")
                (goto-char (point-max))
                (comint-next-input arg)))))

In the next version of Emacs, could we bake this behavior in, so that
shell-mode behaves more intuitively?

Doesn't C-a do that?  It does for me.

I believe Andrew is thinking of the situation where you're on a
different (i.e. previous) line.

This sometimes happens to me too, typically after I've done an isearch
to look at some earlier output. I'm trying out Andrew's idea and so far
I like it.

What about setting comint-scroll-to-bottom-on-input to true?  ()I have that set
when I am in a shell buffer, and any keystrokes move me right to the bottom
and the prompt.)

Documentation:
Controls whether input to interpreter causes window to scroll.
If nil, then do not scroll.  If t or `all', scroll all windows showing buffer.
If `this', scroll only the selected window.

The default is nil.

That's an interesting setting. Though most of my command line interaction
is going up/down in the history and pressing enter, not sure if M-p / M-n
qualifies as input.
