progressive scrolling

progressive scrolling

[Jérôme Bouat]

How can emacs scroll a line progressively
without scrolling one line at a time ?
I like this feature because
it is easier to read a text
when it doesn't jump.
Some other editors do it.
How to set emacs for it ?

Thanks.

Jérôme

Perhaps this is what you want:
(setq scroll-step 1)

Would you mean something like the effect from the following?

M-: (dotimes (i 20) (set-window-vscroll nil (* i 0.05)) (sit-for 0.05)) RET

Thanks, I used (setq scroll-step 1)
instead of what you advised.
I corrected it from now.

For what I wanted,
see the response of David Kastrup.

[plug] ... 

similar "progressiv scrolling" behavior is in a library called vel.el
(see gnu.emacs.sources)...  I am so used to vel now, that haven't used
C-n or C-v in a while...
