Move entire line up and down in Vim

In Notepad++, I can use Ctrl + Shift + Up / Down to move the current line up and down. Is there a similar command to this in Vim?

Answer 1

can use command:

:g/^/move 0

Answer 2

If I want to swap one line with the line above I usually do the following

ddkP

Explanation

• dd will delete the line and add it to the default register.
• k will move up a line (j would move down a line)
• P will paste above the current line

Answer 3

:m.+1 or :m.-2 would do if you're moving a single line. Here's my script to move multiple lines. In visual mode, Alt-up/Alt-down will move the lines containing the visual selection up/down by one line. In insert mode or normal mode, Alt-up/Alt-down will move the current line if no count prefix is given. If there's a count prefix, Alt-up/Alt-down will move that many lines beginning from the current line up/down by one line.

function! MoveLines(offset) range
    let l:col = virtcol('.')
    let l:offset = str2nr(a:offset)
    exe 'silent! :' . a:firstline . ',' . a:lastline . 'm'
        \ . (l:offset > 0 ? a:lastline + l:offset : a:firstline + l:offset)
    exe 'normal ' . l:col . '|'
endf

imap <silent> <M-up> <C-O>:call MoveLines('-2')<CR>
imap <silent> <M-down> <C-O>:call MoveLines('+1')<CR>
nmap <silent> <M-up> :call MoveLines('-2')<CR>
nmap <silent> <M-down> :call MoveLines('+1')<CR>
vmap <silent> <M-up> :call MoveLines('-2')<CR>gv
vmap <silent> <M-down> :call MoveLines('+1')<CR>gv

Answer 4

When you hit command :help move in vim, here is the result:

:[range]m[ove] {address} *:m* *:mo* *:move* *E134* Move the lines given by [range] to below the line given by {address}.

E.g: Move current line one line down => :m+1.

E.g: Move line with number 100 below the line with number 80 => :100 m 80.

E.g: Move line with number 100 below the line with number 200 => :100 m 200.

E.g: Move lines with number within [100, 120] below the line with number 200 => :100,120 m 200.

Answer 5

Move a line up: ddkP

Move a line down: ddp

Answer 6

Put the following to your .vimrc to do the job

noremap <c-s-up> :call feedkeys( line('.')==1 ? '' : 'ddkP' )<CR>
noremap <c-s-down> ddp

Disappearing of the line looks like a Vim bug. I put a hack to avoid it. Probably there is some more accurate solution.

Update

There are a lot of unexplained difficulties with just using Vim combinations. These are line missing and extra line jumping.

So here is the scripting solution which can be placed either inside .vimrc or ~/.vim/plugin/swap_lines.vim

function! s:swap_lines(n1, n2)
    let line1 = getline(a:n1)
    let line2 = getline(a:n2)
    call setline(a:n1, line2)
    call setline(a:n2, line1)
endfunction

function! s:swap_up()
    let n = line('.')
    if n == 1
        return
    endif

    call s:swap_lines(n, n - 1)
    exec n - 1
endfunction

function! s:swap_down()
    let n = line('.')
    if n == line('$')
        return
    endif

    call s:swap_lines(n, n + 1)
    exec n + 1
endfunction

noremap <silent> <c-s-up> :call <SID>swap_up()<CR>
noremap <silent> <c-s-down> :call <SID>swap_down()<CR>
