Select and checkout git branch using fzf in Vim

fzf-branch-checkout.vim

function! GitCheckoutBranch(branch)
    " branch can look like this: "/remotes/origin/master [hash] info" or this: "master [hash] info"
    let l:name = split(split(trim(a:branch), "", 1)[0], "/", 1)[-1]
    
    " just show what is happening
    echo "checking out ".l:name."\n"
    
    " you can use !git, instead of Git, if you don't have Fugitive
    execute "Git checkout ".l:name
endfunction

" -a option lists all branches (remotes aswell)
" -vv option shows more information about branch
" --color and --ansi enables colors
" --nth=1 makes sure you only search by names and not branch info
command! -bang Gbranch call fzf#run(fzf#wrap({'source': 'git branch -avv --color', 'sink': function('GitCheckoutBranch'), 'options': '--ansi --nth=1'}, <bang>0))

Looks like this
