Hi,
I'm trying to figure out why recenter-top-bottom (C-l) isn't working for
me. I find that sometimes it only centers, sometimes it only centers and
'bottoms', and sometimes it behaves as expected. I've done the following
experiment to try and sort this out:
emacs -Q
;; open up a large text file and C-v into the middle
C-l ; works as expected
(setq scroll-conservatively 100) ;; This is part of my .emacs, for
;; smooth scrolling
C-l ;; the 'top' part doesn't work anymore, only 'center' and 'bottom'!
;; Modify the code from recenter-top-bottom (from window.el) as follows:
;; ... begining of function here
(let ((this-scroll-margin
(min (max 0 scroll-margin)
(truncate (/ (window-body-height) 4.0)))))
(message "%d" this-scroll-margin) ;; inserted new code
(cond ((eq recenter-last-op 'middle)
;; end of function here
;; I evaluate my modified function
C-l ;; works again!
This is quite a puzzle to me. Can anyone confirm that C-l behaves the
same on their system? Any explanation for this behaviour?
Thanks,
Tyler
