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'],
  \ 'border':  ['fg', 'Ignore'],
  \ '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.
