newb q: inferior-mode buffer not scrolling

[stevenan]

I'm using emacs to edit ruby, and I have the REPL process in its own
inferior-mode buffer (via inf-ruby.el).  However, when I send it
commands, it doesn't scroll the window down.  So I just always see the
first page of commands...and I have to scroll down to the bottom..  I
use SLIME also, and I never have to do that with its REPL buffer - it
scrolls on its own.  How can I make it auto-scroll?  Should I ask the
ruby ppl instead?  Thanks!

I'm using GNU Emacs 21.3.1 with Win32.

In the inferior ruby buffer, check the values of the comint-scroll-*
variables.  Assuming you want to set comint-scroll-to-bottom-on-input:

(add-hook 'inferior-ruby-mode-hook
           (lambda () (setq comint-scroll-to-bottom-on-input 'this)))

cool!  actually, this ended up working for me:

(add-hook 'inferior-ruby-mode-hook
 '(lambda () (setq comint-scroll-to-bottom-on-output t))) 

thanks!
