Smooth scrolling [Enhancement]

[ReneFroger]

Smooth scroll plugin.

With the following settings:

( require 'smooth-scroll                        ) ;; Smooth scroll 
( smooth-scroll-mode 1                          ) ;; Enable it 
( setq smooth-scroll/vscroll-step-size 5        ) ;; Set the speed right

Try scroll option, or with page-up and page-down. It gives

I believe this is a big improvement. Because when I'm scrolling, I have difficulties to recognize in which way the file was scrolling and where I exactly am. This package helps me with that.

We had a PR a while ago: #1670

But thank you 👍

We are using smooth-scrolling plugin, is this really the same thing as smooth-scroll ?

[sooheon]

Just tested it. They address different issues. The smooth-scrolling we have currently is like vim's scrolloff margin feature, which lets you scroll off screen without the cursor jumping to the center of the screen. smooth-scroll is literally a smoother (graphically), non-instantaneous scroll. Therefore, it cannot replace smooth-scrolling, but it could be an addition for those who want it. Personally I could take it or leave it, this is what I added to my config to make it work if @ReneFroger wants to improve and submit a layer:

(defun sooheon/init-smooth-scroll ()
  (use-package smooth-scroll
    :defer
    :init
    (progn
      (require 'smooth-scroll)
      (smooth-scroll-mode 1)
      (setq smooth-scroll/vscroll-step-size 5))))

@sooheon you are right. I've tested it. It works nicely even on large file. I think this would make a user friendly addition for new comers.

@ReneFroger Thank you for this awesome suggestion. Sorry for not testing it and jump to the conclusion so quickly.

[ReneFroger]

@tuhdo it's not a problem, I was surprised by your first comment, because I considered smooth-scroll to provide much more smooth scrolling than smooth-scrolling. But glad to read that you like it.

By the way, everyone, when you compare it with his Vim counterpart Smooth Scroll , it's even actually bad.

Let me demonstrate it for you:

I couldn't figure out how I could get the scrolling in Emacs so nicely as in Vim. Especially when you tap the scroll action multiple times in row, there is a noticable lag with it in Emacs, while you don't get the lag in Vim.

[tuhdo]

@ReneFroger If you want Emacs scroll faster, try setting smooth-scroll/vscroll-step-size to 10 or higher.

[ReneFroger]

Yes, I'm aware of that. But that's not the problem. It's not so smooth as in Vim, you will notice Emacs scrolls line for line. The scroll configuration in Vim doesn't that.

[sooheon]

That I think is a limitation of emacs, at least from my experience with cocoa emacs on OS X. Even scrolling with the trackpad gives linewise scroll.

[syl20bnr]

For reference I mention here that there is pixel based scrolling with homebrew-emacsmacport version. There is even support for swipe gesture to switch buffer. Very nice version on OS X and one of the ingredients that make some users switch to emacs.

I have the following in my config:

  ;;; scroll one line at a time (less "jumpy" than defaults)
  (setq mouse-wheel-scroll-amount '(2 ((shift) . 1))) ;; two lines at a time
  (setq mouse-wheel-progressive-speed nil) ;; don't accelerate scrolling
  (setq mouse-wheel-follow-mouse 't) ;; scroll window under mouse

Works reasonably well.
