liskin and junegunn [Tags] Workaround for last-position-jump (#810)
If there's an autocmd for BufReadPost that jumps to the last position,
searching for the tag location sometimes results in vim printing the
wrapscan warning and then requires hit-enter. Execute the search
silently to suppress the warning (errors are still visible!).

fzf ❤️ vim

Things you can do with fzf and Vim.


fzf in itself is not a Vim plugin, and the official repository only provides the basic wrapper function for Vim and it's up to the users to write their own Vim commands with it. However, I've learned that many users of fzf are not familiar with Vimscript and are looking for the "default" implementation of the features they can find in the alternative Vim plugins.

This repository is a bundle of fzf-based commands and mappings extracted from my .vimrc to address such needs. They are not designed to be flexible or configurable, and there's no guarantee of backward-compatibility.

Why you should use fzf on Vim

Because you can and you love fzf.

fzf runs asynchronously and can be orders of magnitude faster than similar Vim plugins. However, the benefit may not be noticeable if the size of the input is small, which is the case for many of the commands provided here. Nevertheless I wrote them anyway since it's really easy to implement custom selector with fzf.


fzf.vim depends on the basic Vim plugin of the main fzf repository, which means you need to set up both "fzf" and "fzf.vim" on Vim. To learn more about fzf/Vim integration, see README-VIM.

Using vim-plug

If you already installed fzf using Homebrew, the following should suffice:

Plug '/usr/local/opt/fzf'
Plug 'junegunn/fzf.vim'

But if you want to install fzf as well using vim-plug:

Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' }
Plug 'junegunn/fzf.vim'
  • dir and do options are not mandatory
  • Use ./install --bin instead if you don't need fzf outside of Vim
  • Make sure to use Vim 7.4 or above

Commands Commands
Maps Normal mode mappings
Helptags Help tags 1
Filetypes File types
  • Most commands support CTRL-T / CTRL-X / CTRL-V key bindings to open in a new tab, a new split, or in a new vertical split
  • Bang-versions of the commands (e.g. Ag!) will open fzf in fullscreen
  • You can set g:fzf_command_prefix to give the same prefix to the commands
    • e.g. let g:fzf_command_prefix = 'Fzf' and you have FzfFiles, etc.

(1: Helptags will shadow the command of the same name from pathogen. But its functionality is still available via call pathogen#helptags(). )


Global options

See of the main fzf repository for details.

" This is the default extra key bindings
let g:fzf_action = {
  \ 'ctrl-t': 'tab split',
  \ 'ctrl-x': 'split',
  \ 'ctrl-v': 'vsplit' }

" Default fzf layout
" - down / up / left / right
let g:fzf_layout = { 'down': '~40%' }

" In Neovim, you can set up fzf window using a Vim command
let g:fzf_layout = { 'window': 'enew' }
let g:fzf_layout = { 'window': '-tabnew' }
let g:fzf_layout = { 'window': '10split' }

" Customize fzf colors to match your color scheme
let g:fzf_colors =
\ { 'fg':      ['fg', 'Normal'],
  \ 'bg':      ['bg', 'Normal'],
  \ 'hl':      ['fg', 'Comment'],
  \ 'fg+':     ['fg', 'CursorLine', 'CursorColumn', 'Normal'],
  \ 'bg+':     ['bg', 'CursorLine', 'CursorColumn'],
  \ 'hl+':     ['fg', 'Statement'],

  \ 'header':  ['fg', 'Comment'] }

" Enable per-command history.
" CTRL-N and CTRL-P will be automatically bound to next-history and
" previous-history instead of down and up. If you don't like the change,
" explicitly bind the keys to down and up in your $FZF_DEFAULT_OPTS.
let g:fzf_history_dir = '~/.local/share/fzf-history'

Command-local options

" [Buffers] Jump to the existing window if possible
let g:fzf_buffers_jump = 1

" [[B]Commits] Customize the options used by 'git log':
let g:fzf_commits_log_options = '--graph --color=always --format="%C(auto)%h%d %s %C(black)%C(bold)%cr"'

" [Tags] Command to generate tags file
let g:fzf_tags_command = 'ctags -R'

" [Commands] --expect expression for directly executing the command
let g:fzf_commands_expect = 'alt-enter,ctrl-x'

Advanced customization

You can use autoload functions to define your own commands.

" Command for git grep
" - fzf#vim#grep(command, with_column, [options], [fullscreen])
command! -bang -nargs=* GGrep
  \ call fzf#vim#grep(
  \   'git grep --line-number '.shellescape(<q-args>), 0,
  \   { 'dir': systemlist('git rev-parse --show-toplevel')[0] }, <bang>0)

" Override Colors command. You can safely do this in your .vimrc as fzf.vim
" will not override existing commands.
command! -bang Colors
  \ call fzf#vim#colors({'left': '15%', 'options': '--reverse --margin 30%,0'}, <bang>0)

" Augmenting Ag command using fzf#vim#with_preview function
"   * fzf#vim#with_preview([[options], [preview window], [toggle keys...]])
"     * For syntax-highlighting, Ruby and any of the following tools are required:
"       - Bat:
"       - Highlight:
"       - CodeRay:
"       - Rouge:
"   :Ag  - Start fzf with hidden preview window that can be enabled with "?" key
"   :Ag! - Start fzf in fullscreen and display the preview window above
command! -bang -nargs=* Ag
  \ call fzf#vim#ag(<q-args>,
  \                 <bang>0 ? fzf#vim#with_preview('up:60%')
  \                         : fzf#vim#with_preview('right:50%:hidden', '?'),
  \                 <bang>0)

" Similarly, we can apply it to fzf#vim#grep. To use ripgrep instead of ag:
command! -bang -nargs=* Rg
  \ call fzf#vim#grep(
  \   'rg --column --line-number --no-heading --color=always --smart-case '.shellescape(<q-args>), 1,
  \   <bang>0 ? fzf#vim#with_preview('up:60%')
  \           : fzf#vim#with_preview('right:50%:hidden', '?'),
  \   <bang>0)

" Likewise, Files command with preview window
command! -bang -nargs=? -complete=dir Files
  \ call fzf#vim#files(<q-args>, fzf#vim#with_preview(), <bang>0)


Mapping Description

<plug>(fzf-complete-file) File completion using find
<plug>(fzf-complete-file-ag) File completion using ag

" Mapping selecting mappings
nmap <leader><tab> <plug>(fzf-maps-n)
xmap <leader><tab> <plug>(fzf-maps-x)
omap <leader><tab> <plug>(fzf-maps-o)

" Insert mode completion

imap <c-x><c-f> <plug>(fzf-complete-path)
imap <c-x><c-j> <plug>(fzf-complete-file-ag)
imap <c-x><c-l> <plug>(fzf-complete-line)

" Advanced customization using autoload functions
inoremap <expr> <c-x><c-k> fzf#vim#complete#word({'left': '15%'})

Completion helper

fzf#vim#complete is a helper function for creating custom fuzzy completion using fzf. If the first parameter is a command string or a Vim list, it will be used as the source.

" Replace the default dictionary completion with fzf-based fuzzy completion
inoremap <expr> <c-x><c-k> fzf#vim#complete('cat /usr/share/dict/words')

For advanced uses, you can pass an options dictionary to the function. The set of options is pretty much identical to that for fzf#run only with the following exceptions:

  • reducer (funcref)
    • Reducer transforms the output lines of fzf into a single string value
  • prefix (string or funcref; default: \k*$)
    • Regular expression pattern to extract the completion prefix
    • Or a function to extract completion prefix
  • Both source and options can be given as funcrefs that take the completion prefix as the argument and return the final value
  • sink or sink* are ignored
" Global line completion (not just open buffers. ripgrep required.)
inoremap <expr> <c-x><c-l> fzf#vim#complete(fzf#wrap({
  \ 'prefix': '^.*$',
  \ 'source': 'rg -n ^ --color always',
  \ 'options': '--ansi --delimiter : --nth 3..',
  \ 'reducer': { lines -> join(split(lines[0], ':\zs')[2:], '') }}))

Reducer example

function! s:make_sentence(lines)
  return substitute(join(a:lines), '^.', '\=toupper(submatch(0))', '').'.'

inoremap <expr> <c-x><c-s> fzf#vim#complete({
  \ 'source':  'cat /usr/share/dict/words',
  \ 'reducer': function('<sid>make_sentence'),
  \ 'options': '--multi --reverse --margin 15%,0',
  \ 'left':    20})

Status line of terminal buffer

When fzf starts in a terminal buffer (see fzf/, you may want to customize the statusline of the containing buffer.

Hide statusline

autocmd! FileType fzf
autocmd  FileType fzf set laststatus=0 noshowmode noruler
  \| autocmd BufLeave <buffer> set laststatus=2 showmode ruler

Custom statusline

function! s:fzf_statusline()
  " Override statusline as you like
  highlight fzf1 ctermfg=161 ctermbg=251
  highlight fzf2 ctermfg=23 ctermbg=251
  highlight fzf3 ctermfg=237 ctermbg=251
  setlocal statusline=%#fzf1#\ >\ %#fzf2#fz%#fzf3#f

autocmd! User FzfStatusLine call <SID>fzf_statusline()



You can’t perform that action at this time.
