How do you exit vimdiff mode in vim, specifically, for Fugitive?

Question

I am using vim with the fugitive extension. It has a :Gdiff command which brings you into vimdiff mode, but what is the right/quick way to close/quit vimdiff mode?

I.e., let's say I am editing the file FooBar.txt under Git repository. I fire up :Gdiff, review my changes in vimdiff, and then I want to get back and continue editing FooBar.txt or any other file :)

UPDATE1: I'm going to give these quick combos a try next working day :)

"vimdiff current vs git head (fugitive extension)
nnoremap <Leader>gd :Gdiff<cr> 
"switch back to current file and closes fugitive buffer
nnoremap <Leader>gD :diffoff!<cr><c-w>h:bd<cr>

UPDATE2: My current mappings (closes diff window only!)

"vimdiff current vs git head (fugitive extension)
nnoremap <Leader>gd :Gdiff<cr> 
"switch back to current file and closes fugitive buffer
nnoremap <Leader>gD <c-w>h<c-w>c

Also, please help me decide if the following should be an anwser: https://stackoverflow.com/a/15975201/275980

Answer 1

You can execute windo set nodiff noscrollbind and then close the second window.

Update: there is a diffoff command. Use windo diffoff, not what I wrote in previous line.

Answer 2

According to: https://github.com/tpope/vim-fugitive/issues/36

Close the other window. The easiest way to do this if you haven't shifted focus to it is <C-W><C-O>, which means "make this Window the Only window."

Answer 3

I had no luck with diffoff, but I just learned that :Gedit with no argument will bring you back to the working-directory version of the file, as opposed to some earlier version you were reviewing.

And as q (no need for :q) will close the diff sidebar, you can do q followed by :Gedit to get rid of the sidebar and then go back to the current version of the file.

Answer 4

This works fine for me, combining some of the existing ideas here:

function! MyCloseDiff()
  if (&diff == 0 || getbufvar('#', '&diff') == 0)
        \ && (bufname('%') !~ '^fugitive:' && bufname('#') !~ '^fugitive:')
    echom "Not in diff view."
    return
  endif

  " close current buffer if alternate is not fugitive but current one is
  if bufname('#') !~ '^fugitive:' && bufname('%') =~ '^fugitive:'
    if bufwinnr("#") == -1
      b #
      bd #
    else
      bd
    endif
  else
    bd #
  endif
endfunction
nnoremap <Leader>gD :call MyCloseDiff()<cr>

Answer 5

I've found a simple solution for this. You can check it here: https://gist.github.com/radmen/5048080

" Simple way to turn off Gdiff splitscreen
" works only when diff buffer is focused
if !exists(":Gdiffoff")
  command Gdiffoff diffoff | q | Gedit
endif

Answer 6

None of the above solutions worked for me. Ended up doing this instead:

nnoremap <Leader>D :Gedit<CR><C-w>h :q<CR><C-w>k

Answer 7

An alternative to <C-W><C-O>, if you have multiple windows, would be move to the other diff window and do <C-W>c, which close only one window.

If you close the wrong diff window do a :Gedit

Be careful and don't confuse <C-W>c with <C-W><C-C>

Answer 8

this is what I have to leave the vimdiff windows after using :Gdiff

nnoremap gD :q!<CR> :Gedit!<CR>

Answer 9

noremap <leader>do :diffoff \| windo if &diff \| hide \| endif<cr>

Quite diff mode and close other diff windows. (Note: fugitive will auto delete its hidden buffers.)

Answer 10

My function will work both from diff window and file window. But probably won't handle itself with multiple diffs opened. For that you'll need to use fugitive#buffer(n).path() to scan and match.

command! Gdiffoff call Gdiffoff()
function! Gdiffoff()
    let diffbufnr = bufnr('^fugitive:')
    if diffbufnr > -1 && &diff
        diffoff | q
        if bufnr('%') == diffbufnr | Gedit | endif
        setlocal nocursorbind
    else
        echo 'Error: Not in diff or file'
    endif
endfunction

Add a key binding:

nnoremap <silent> <leader>gD :Gdiffoff<CR>

Answer 11

Yet another way. What I have in fugitive.vim - first save some info (s:gitbufname) when diff starts:

function! s:Diff(vert,...) abort
  call sy#toggle()
  let s:startcol = winwidth(0)
  let &columns=(winwidth(0) * 2 - 20)
...
    if getwinvar('#', '&diff')
      let s:gitbufname = bufname("%")
      wincmd p
      call feedkeys(winnr."\<C-W>w", 'n')
    endif
...
endfunction

and later when leaving the buffer switch window to the saved buffer and restore:

augroup fugitive_diff
autocmd!
autocmd BufWinLeave *
  \ if s:can_diffoff(+expand('<abuf>')) && s:diff_window_count() == 2 |
  \   if exists('s:gitbufname') && winnr() != bufwinnr(s:gitbufname) |
  \     let nr = bufnr("%") | exe bufwinnr(s:gitbufname).'wincmd w' | exe 'buf'.nr |
  \   endif |
  \   call s:diffoff_all(getbufvar(+expand('<abuf>'), 'git_dir')) |
  \   call sy#toggle() |
  \   call airline#load_theme() | call airline#update_statusline() |
  \   let &columns=s:startcol |
  \ endif
...

Answer 12

Check the vimdiff toggling between diffthis and diffoff here at this page.

The code:

nnoremap <silent> <Leader>df :call DiffToggle()<CR>

function! DiffToggle()
    if &diff
        diffoff
    else
        diffthis
    endif
:endfunction

Answer 13

Method 1:

• open a compare by:

:windo diffthis

• close it by:

:windo diffoff

Method 2:

I recommend just using the most simple command: :q<CR>

when you want to do it quickly, add the mapping:

" Set mapleader
let mapleader = ","
let g:mapleader = ","

and

" Quickly close the current window
nnoremap <leader>q :q<CR>

It works well for me. Exit vimdiff just by ,q, because normally your cursor in the old file.

Answer 14

Was using the code below based on https://stackoverflow.com/a/15113951/10999673 :

    if !exists(":Gdiffoff")
        command Gdiffoff bw! fugitive://*
    endif

but it gave me an error "E93: more than one match for ..." in a 3 way diff, so i instead used the answer from https://stackoverflow.com/a/4867969/10999673 and finally have this:

function! GetBufferList()
    return filter(range(1,bufnr('$')), 'buflisted(v:val)')
endfunction

function! GetMatchingBuffers(pattern)
    return filter(GetBufferList(), 'bufname(v:val) =~ a:pattern')
endfunction

function! WipeMatchingBuffers(pattern)
    let l:matchList = GetMatchingBuffers(a:pattern)

    let l:count = len(l:matchList)
    if l:count < 1
        echo 'No buffers found matching pattern ' . a:pattern
        return
    endif

    if l:count == 1
        let l:suffix = ''
    else
        let l:suffix = 's'
    endif

    exec 'bw ' . join(l:matchList, ' ')

    echo 'Wiped ' . l:count . ' buffer' . l:suffix . '.'
endfunction

command! -nargs=1 Gdiffoff call WipeMatchingBuffers('fugitive://')

I just tweaked, copied and pasted the code into my .vimrc

Answer 15

Running :Gwrite after merging to your satisfaction will close the other two diff panes in addition to updating the git cache to mark the file as merged.
