SimpleSmoothScroll is a simple Vim global plugin for giving a smoothed effect to Ctrl-D and Ctrl-U.
I originally created this script for myself when I was looking through large code files in a legacy code base and I was having trouble keeping track of where I was in all the spaghetti. The smooth scroll action gave me a better sense of my own navigation.
I originally published this code on StackOverflow.
The current version has been fixed up some in an attempt to be a little more
readable and conform to the guidelines put forth in :help write-script.
I've also used this as a chance to begin learning to use Github. At the time I wrote this, I did not realize that there were many existing smooth scroll plugins. To be honest, I haven't looked into any of them. They might be better than this.
- Scroll on the basis of the Vim
scrolloption. - If you set the mouse option for some modes, you can scroll with the mouse wheel in those modes.
- Manually customizable scrolling speed (adjust the
sleepcommand's time argument; I use ten milliseconds). Note: just like slowing down the frame rate on a video, if you slow down the smooth scroll too much it will be jerky scroll. already in insert mode) - Simple and lightweight
I've found that you shouldn't push Ctrl-D or Ctrl-U until the previous scroll has finished, or the behavior is somewhat unpredictable. I have mostly experienced this problem when dealing with very large files over a painfully slow network connection.
I recommend installing pathogen.vim, and then executing:
cd ~/.vim/bundle
git clone https://github.com/Kazark/vim-SimpleSmoothScroll.git
or the equivalent. Alternatively, you can copy plugin/SimpleSmoothScroll.vim
to ~/.vim/plugin. (Note: you may have to use ~\vimfiles instead of
~/.vim if you are on Windows...)
By default and have different purposes in insert mode. However if you would like to have scroll working as normal mode, add the lines below to your vimrc file.
inoremap <C-U> <Esc><C-U>i
inoremap <C-D> <Esc><C-D>i
