Is it possible to set scrolloff to top and bottom with different values?

Question

As title. For example, say I imagine there is something like scrolloffTop and scrolloffBottom and I can set each with different values. If there is no such options, I would like to know is it possible to achieve this by script.

Answer 1

Here's a script that will set a different scrolloff value when the cursor is in the top or bottom half of the window (12 and 0 respectively in the example).

It uses the CursorMoved event, which will trigger quite often. This might not be the best approach.

augroup switchScrolloffTopBottom
  autocmd!
  autocmd CursorMoved * if winline() < &lines/2
        \| setlocal scrolloff=12
        \|else
        \| setlocal scrolloff=0 
        \|endif
augroup END
