local target_lnum = vim.api.nvim_win_get_cursor(0)[1] + screen_h / 2
local step = screen_h / 2 / 50
step = step >= 1 and step or 1
require("scroll").scroll(target_lnum, function(current_line, target_line)
local fold_end = vim.fn.foldclosedend(current_line)
-- if current_line is not in a fold
if fold_end < 0 then
return {
-- cursor position in next step
next_line = current_line + step,
-- delay 10ms for next step
delay = 10,
}
end
local fold_start = vim.fn.foldclosed(current_line)
return {
next_line = fold_end + 1,
delay = 10,
-- when current_line is in a fold, you may want to regard it as one line, then you need to change the target_line
