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.,

Answer 1

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  gD :Gdiffoff
