How to swap files between windows in VIM?

I wrote and have been using the following code snippet in my vimrc for copy-pasting my Vim windows.

This defines for example the following shortcuts:

• <c-w>y: "Yanks the window", i.e. stores the number of the buffer in the current window in a global variable.
• <c-w>pp: "Puts the window in Place of the current window", i.e. it reads the buffer number stored previously and opens that buffer in the current window. It also stores the number of the buffer that used to be in the current window.

If by "swapping those windows in places", you mean "opening the buffer in window A in window B, and vice versa, without changing the position of the windows", you can use the following keyboard sequence to swap the windows:

1. Select window A (either with mouse or with keyboard commands)
2. Press <c-w>y (yanking the buffer number)
3. Select window B
4. Press <c-w>pp (pasting the buffer)
5. Select window A
6. Press <c-w>pp (pasting the buffer again)

It works only in Vim >= 7.0.

if version >= 700
function! HOpen(dir,what_to_open)

    let [type,name] = a:what_to_open

    if a:dir=='left' || a:dir=='right'
        vsplit
    elseif a:dir=='up' || a:dir=='down'
        split
    end

    if a:dir=='down' || a:dir=='right'
        exec "normal! \<c-w>\<c-w>"
    end

    if type=='buffer'
        exec 'buffer '.name
    else
        exec 'edit '.name
    end
endfunction

function! HYankWindow()
    let g:window = winnr()
    let g:buffer = bufnr('%')
    let g:bufhidden = &bufhidden
endfunction

function! HDeleteWindow()
    call HYankWindow()
    set bufhidden=hide
    close
endfunction

function! HPasteWindow(direction)
    let old_buffer = bufnr('%')
    call HOpen(a:direction,['buffer',g:buffer])
    let g:buffer = old_buffer
    let &bufhidden = g:bufhidden
endfunction

noremap <c-w>d :call HDeleteWindow()<cr>
noremap <c-w>y :call HYankWindow()<cr>
noremap <c-w>p<up> :call HPasteWindow('up')<cr>
noremap <c-w>p<down> :call HPasteWindow('down')<cr>
noremap <c-w>p<left> :call HPasteWindow('left')<cr>
noremap <c-w>p<right> :call HPasteWindow('right')<cr>
noremap <c-w>pk :call HPasteWindow('up')<cr>
noremap <c-w>pj :call HPasteWindow('down')<cr>
noremap <c-w>ph :call HPasteWindow('left')<cr>
noremap <c-w>pl :call HPasteWindow('right')<cr>
noremap <c-w>pp :call HPasteWindow('here')<cr>
noremap <c-w>P :call HPasteWindow('here')<cr>

endif

There are a few useful commands built in which give you a certain amount of control, but it's not comprehensive. The main ones are:

• Ctrl-W, r (i.e. hold CTRL, press W, release CTRL, press r) - which rotates the windows (The first window becomes the second one, the second one becomes the third one, etc.)

• Ctrl-W, x - swap the current window with the next one

• Ctrl-W, Shift-H - move this window to the far left

• Ctrl-W, Shift-K - move this window to the top

(and similarly for Ctrl-W, Shift-J and Ctrl-W, Shift-L). See:

:help window-moving

for more information.
