FZF Vim integration

This repository only enables basic integration with Vim. If you're looking for more, check out fzf.vim project.

(Note: To use fzf in GVim, an external terminal emulator is required.)

:FZF[!]

If you have set up fzf for Vim, :FZF command will be added.

" Look for files under current directory
:FZF

" Look for files under your home directory
:FZF ~

" With options
:FZF --no-sort --reverse --inline-info /tmp

" Bang version starts fzf in fullscreen mode
:FZF!

Similarly to ctrlp.vim, use enter key, CTRL-T, CTRL-X or CTRL-V to open selected files in the current window, in new tabs, in horizontal splits, or in vertical splits respectively.

Note that the environment variables FZF_DEFAULT_COMMAND and FZF_DEFAULT_OPTS also apply here.

Configuration

• g:fzf_action
  • Customizable extra key bindings for opening selected files in different ways
• g:fzf_layout
  • Determines the size and position of fzf window (tmux pane or Neovim split)
• g:fzf_colors
  • Customizes fzf colors to match the current color scheme
• g:fzf_history_dir
  • Enables history feature
• g:fzf_launcher
  • (Only in GVim) Terminal emulator to open fzf with
  • g:Fzf_launcher for function reference

Examples

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

" An action can be a reference to a function that processes selected lines
function! s:build_quickfix_list(lines)
  call setqflist(map(copy(a:lines), '{ "filename": v:val }'))
  copen
  cc
endfunction

let g:fzf_action = {
  \ 'ctrl-q': function('s:build_quickfix_list'),
  \ '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 enew' }

" 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'],
  \ 'info':    ['fg', 'PreProc'],
  \ 'prompt':  ['fg', 'Conditional'],
  \ 'pointer': ['fg', 'Exception'],
  \ 'marker':  ['fg', 'Keyword'],
  \ 'spinner': ['fg', 'Label'],
  \ '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'

fzf#run

For more advanced uses, you can use fzf#run([options]) function with the following options.

Option name	Type	Description
source	string	External command to generate input to fzf (e.g. find .)
source	list	Vim list as input to fzf
sink	string	Vim command to handle the selected item (e.g. e, tabe)
sink	funcref	Reference to function to process each selected item
sink*	funcref	Similar to sink, but takes the list of output lines at once
options	string/list	Options to fzf
dir	string	Working directory
up/down/left/right	number/string	Use tmux pane with the given size (e.g. 20, 50%)
window (Neovim only)	string	Command to open fzf window (e.g. vertical aboveleft 30new)
launcher	string	External terminal emulator to start fzf with (GVim only)
launcher	funcref	Function for generating launcher string (GVim only)

options entry can be either a string or a list. For simple cases, string should suffice, but prefer to use list type if you're concerned about escaping issues on different platforms.

call fzf#run({'options': '--reverse --prompt "C:\\Program Files\\"'})
call fzf#run({'options': ['--reverse', '--prompt', 'C:\Program Files\']})

fzf#wrap

fzf#wrap([name string,] [opts dict,] [fullscreen boolean]) is a helper function that decorates the options dictionary so that it understands g:fzf_layout, g:fzf_action, g:fzf_colors, and g:fzf_history_dir like :FZF.

command! -bang MyStuff
  \ call fzf#run(fzf#wrap('my-stuff', {'dir': '~/my-stuff'}, <bang>0))

GVim

In GVim, you need an external terminal emulator to start fzf with. xterm command is used by default, but you can customize it with g:fzf_launcher.

" This is the default. %s is replaced with fzf command
let g:fzf_launcher = 'xterm -e bash -ic %s'

" Use urxvt instead
let g:fzf_launcher = 'urxvt -geometry 120x30 -e sh -c %s'

If you're running MacVim on OSX, I recommend you to use iTerm2 as the launcher. Refer to the this wiki page to see how to set up.
