Vim scripting: Preserve cursor position and screen view in function call

vim

Solution

let l:winview = winsaveview()
" do stuff
call winrestview(l:winview)

This should pretty much do exactly what you want it to do, possibly excepting the line count changing above the cursor (I suspect that deleted lines above the cursor would have the effect of moving the cursor down).

Problem

I have some Vim functions that make changes to the document format. When I call this function, I currently use something like the following to save and restore my cursor position: ``` func! Foo() :norm mz ... :norm `z endf ``` This properly saves the cursor position, but it sometimes changes the window position, so that the current line moves from being near the top of the screen to being near the bottom or vice versa. Is there a way to preserve both cursor position and the on-screen position of the line?
