Vim : swap 2 distant lines in one move

(NB : my first post)

In a Vim file, how may I swap - in one move - line 15 and line 33 (e.开发者_运维知识库g.) ?

Fastest way is to move lines:

:33m 15|15m 33

Move line 33 below line 15, then moves line 15 below line 33.

It's best to do it 'move high-number below low-number' first, otherwise you have to adjust offsets:

:15m 33|32m 14

Two ways I can think of. With Vim there are probably more!

:33 | delete | 15 | put | 15 | delete | 32 | put

...or...

13ggdd15ggPjdd33ggP

...which is fewer keystrokes but a little less comprehensible when written down!

I've found this command to be the fastest way if I'm in the file:

:15mo33

I'm frequently using the following:

" Tip #470 : Piet Delport & Anthony (ad_scriven)
vnoremap <silent> g" <esc>:call <sid>SwapVisualWithCut()<cr>

function! s:SwapVisualWithCut()
  normal! `.``
  if line(".")==line("'.") && col(".") < col("'.")
    let c = col('.')
    normal! gvp```]
    let c = col('.') - c
    normal! ``
    :silent call cursor(line("."),col(".")+c)
    normal! P
  else
    normal! gvp``P
  endif
endfunction

The idea is to delete something anywhere, then go select characters elsewhere, and hit g" to swap the delete characters with the newly selected ones.
