Smooth Scrolling in Vim
- I have been working on a script to allow smooth scrolling in Vim. I
got it working pretty well, even with a variable pause in between
steps (currently set to speed up for the first 80% of iterations, and
then slow down at the end). I am happy with the result for the most
part, but have an issue with the speed of the scroll especially when
the window is maximized on slow machines. Right now, I am only
setting a delay between steps of 5ms, but it still is taking a bit of
time with 0. I was wondering if there were any ideas of anything I
can be doing differently to get it sped up.
" Smooth Scrolling
nnoremap <c-d> :call DelayedFunc("normal! gjzz",winheight(".")/
nnoremap <c-u> :call DelayedFunc("normal! gkzz",winheight(".")/
" cmd , iter , delay
if a:0 == 2
let iter = a:1
let delay = a:2
let i = 0
" first section
let ot = iter/5*4
let start = range(100,0,eval(-100/(ot-1)))
" second section
let tt = iter - ot
let end = range(0,100,eval(100/(tt-1)))
" list of speeds
let speed = start + end
if a:cmd != ""
while i < iter
exec "sleep " . eval(delay*speed[i]/100) . "m"
let i = i + 1
