Smooth scrolling issue in VIM

[jmagaram]

Whenever I do scrolling in VIM mode with ctrl+d and ctrl+u it jumps up and down instantly. I find this very disconcerting and disorienting. I've completely lost my context and feel like I've randomly jumped somewhere else is the file. Is there some way to smoothly scroll a bit up and down without this happening? Maybe I want that feature where the cursor stays in one place but want to go up and down a few lines instead of just one.

I've been researching this a bit. VS Code has this feature - "Editor: Smooth Scrolling". It makes a difference because when I was using VS Code, scrolling with Ctrl+D and Ctrl+U felt ok. When I switched to Zed something didn't feel right and I constantly felt lost in my code and felt the need to turn on the outline. Now I know why. Smooth scrolling would be great, but a physics based scrolling would be better, where the scrolling speeds up and then gently slows down once you arrive at the destination. I think this would show off a unique capability in Zed - the game-like rendering.

You can get this kind of scrolling in VIM. A quick search turned up https://github.com/yuttie/comfortable-motion.vim and https://github.com/karb94/neoscroll.nvim

This belongs to the animation category, and this addition is very easy, what you said about physics is just a distinction of easing.

It's worth mentioning that currently, copying highlighting is just a simple display setting, which only delays and then clears, and cannot achieve a smooth animation effect.

      editor.highlight_background::<HighlightOnYank>(
            &ranges_to_highlight,
            |colors| colors.editor_document_highlight_read_background,
            cx,
        );
        cx.spawn(|this, mut cx| async move {
            cx.background_executor()
                .timer(Duration::from_millis(highlight_duration))
                .await;
            this.update(&mut cx, |editor, cx| {
                editor.clear_background_highlights::<HighlightOnYank>(cx)
            })
            .ok();
        })
        .detach();
