annoying shell problem in GNU Emacs 22

annoying shell problem in GNU Emacs 22

[rocksong23]

Hi all,

I'm having an annoying problem with the shell mode in GNU emacs 22.1.1
which I haven't had in earlier versions (including emacs 21): if I
have more than a screenful in my shell buffer, then whenever I execute
a command, my window re-aligns so that the bottom of the buffer is at
the
bottom of the window.

In other words: I go to the command line at the end of the buffer, hit
ctrl-L (so that my command line is in the middle of my screen, where I
like it). Then when I hit return or execute a command, my command line
is suddenly at the bottom of my screen (where I don't like it).

Does that make sense? Like I said, it is really annoying. So if anyone
can point me to a setting to fix this, it'd be much appreciated.

Thanks, Peter

Set the (buffer-local) variable comint-scroll-show-maximum-output to nil.

Remove the function comint-postoutput-scroll-to-bottom from the list
in the variable comint-output-filter-functions:

(setq comint-output-filter-functions '(comint-watch-for-password-prompt))

halfway readable and gets the job done before your boss fires you.

Argh.

(remove-hook 'comint-output-filter-functions 
'comint-postoutput-scroll-to-bottom)

Not sure what happened with my last reply, but Kevin's fix worked
best, i.e.:

(remove-hook 'comint-output-filter-functions
'comint-postoutput-scroll-to-bottom)

(Glenn's fix [Set the (buffer-local) variable comint-scroll-show-
maximum-output to nil] worked but had to be applied to every shell
buffer).

Thanks to all who replied.

That's what shell-mode-hook is for.

Applying that selectivity to Ivan's solution (which I modified):

(add-hook 'shell-mode-hook
	  (lambda ()
	    (remove-hook 'comint-output-filter-functions
			 'comint-postoutput-scroll-to-bottom
			 t)))		; LOCAL
