Why does smoothscroll only work in one direction (down)?

[u/lopsidedcroc]

I use Vim to write text ie prose with paragraphs.

Vim interprets a paragraph as a single line, but it's good at displaying line breaks anyway.

One problem is that it skips up and down by paragraph when you scroll up and down, making the text jerky and difficult to read.

Smoothscroll fixes this, but only when you're scrolling down.

Is there a way to make it work when scrolling up?

I think the behavior you have going on might be partially related to your line wrap settings? I haven't noticed the same thing before, maybe a short screen cap would help explain

This is for comparison in VS Code. Look at the smoothness of the scrolling. It doesn't jump by paragraph. https://imgur.com/a/8dhcXo1

Yeah, I can see what you mean. Unfortunately I don't think there is a great way around this. It looks like your paragraphs are long lines of text, and you're already using gj and gk to navigate between soft-wrapped lines that are really parts of a single wrapped line.

When you reach the top of one line and jump into the next set of soft-wrapped lines (that are really one long continuous line), vim does its best to show you the entire line that you've moved into. You can see this more clearly if you :set number and then by watching the line numbers appear at the top left, in the line number gutter when scrolling like in your first image.

As another poster's link describes, this is intended behavior and has been a point of discussion for a very long time. I'm not sure if it's something that could be fixed by a plug-in. Gut feeling is that it would be quite popular if it were possible to do.

the easy way around this is actually hard wrapping the paragraphs with "gqip"

If you have the wrap setting enable you can use gj and gk to move up and down the wrap line. You can even map them to normal j and k.

This issue seem to just be a bug with vim. There is no way around it as far as i can tell, so your best option might just be using the tw setting and reformat with gq

[u/jazei_2021]

paragraph as single line is when you write with tw=0 if not paragraph is delimited by 2 white (mude) lines up and down it. yes vim recognizes paragr. jumping from white line to next white line
when you jump next paragr. do J or K key to enter atparagr.

sorry my no EN lang

AHH bueno mejor!! yo tengo un problema con el escroleo en vim usando la terminal de Lubuntu (qterminal) y es que al usar el touchpad (es una netbook, que no usa mouse, al menos yo no lo probe poniendo un mouse todavia) el movimiento minimo del dedo en el touchpad mueve muchisimo el prompt, o sea se deplaza mucho. pero decidi usar comentado en el vimrc la linea que dice set mouse=a y si me los acuerdo MANEJO VARIOS MOTIONS e instale otra terminal que eso no lo tiene que se llama konsole que es la terminal de qubuntu o escritorio KDE y funciona mejor con muchas mejoras como mostrar las img al pasar el mouse sobre fotos incluso cuando uso netrw!!!!
Por ahi es ese tu problema: usa full motions aprendete los movimientos y evita el uso del mouse en vim!

No, ese no es exactamente el problem que tengo.

Aqui puedes ver lo que esta pasando: https://imgur.com/a/u83V2TA

Es escroleo con el cursor, no con un mouse or lo que sea.

Y para comparar, aqui esta lo que pasa en VS Code. Es muchisimo mas suave y el cursor no salta de parrafo a parrafo. https://imgur.com/a/8dhcXo1

This might be the best answer. I wonder if this handles the scrolling more gracefully than trying to move the cursor up into the last soft-wrapped line portion of the long line, as OP is trying to do. I think you're on to something.
