FZF Vim integration¶ ↑
Installation¶ ↑
Once you have fzf installed, you can enable it inside Vim simply by adding the directory to &runtimepath
in your Vim configuration file. The path may differ depending on the package manager.
" If installed using Homebrew set rtp+=/usr/local/opt/fzf " If installed using git set rtp+=~/.fzf
If you use vim-plug, the same can be written as:
" If installed using Homebrew Plug '/usr/local/opt/fzf' " If installed using git Plug '~/.fzf'
But if you want the latest Vim plugin file from GitHub rather than the one included in the package, write:
Plug 'junegunn/fzf'
The Vim plugin will pick up fzf binary available on the system. If fzf is not found on $PATH
, it will ask you if it should download the latest binary for you.
To make sure that you have the latest version of the binary, set up post-update hook like so:
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
Summary¶ ↑
The Vim plugin of fzf provides two core functions, and :FZF
command which is the basic file selector command built on top of them.
-
fzf#run([spec dict])
-
Starts fzf inside Vim with the given spec
-
:call fzf#run({'source': 'ls'})
-
-
fzf#wrap([spec dict]) -> (dict)
-
Takes a spec for
fzf#run
and returns an extended version of it with additional options for addressing global preferences (g:fzf_xxx
)-
:echo fzf#wrap({'source': 'ls'})
-
-
We usually wrap a spec with
fzf#wrap
before passing it tofzf#run
-
:call fzf#run(fzf#wrap({'source': 'ls'}))
-
-
-
:FZF [fzf_options string] [path string]
-
Basic fuzzy file selector
-
A reference implementation for those who don't want to write VimScript to implement custom commands
-
If you're looking for more such commands, check out fzf.vim project.
-
The most important of all is fzf#run
, but it would be easier to understand the whole if we start off with :FZF
command.
:FZF[!]
¶ ↑
" Look for files under current directory :FZF " Look for files under your home directory :FZF ~ " With fzf command-line options :FZF --reverse --info=inline /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
-
-
g:fzf_colors
-
Customizes fzf colors to match the current color scheme
-
-
g:fzf_history_dir
-
Enables history feature
-
Examples¶ ↑

Explanation of g:fzf_colors
¶ ↑
g:fzf_colors
is a dictionary mapping fzf elements to a color specification list:
element: [ component, group1 [, group2, ...] ]
-
element
is an fzf element to apply a color to:
| Element | Description | | — | — | | fg
/ bg
/ hl
| Item (foreground / background / highlight) | | fg+
/ bg+
/ hl+
| Current item (foreground / background / highlight) | | preview-fg
/ preview-bg
| Preview window text and background | | hl
/ hl+
| Highlighted substrings (normal / current) | | gutter
| Background of the gutter on the left | | pointer
| Pointer to the current line (>
) | | marker
| Multi-select marker (>
) | | border
| Border around the window (--border
and --preview
) | | header
| Header (--header
or --header-lines
) | | info
| Info line (match counters) | | spinner
| Streaming input indicator | | query
| Query string | | disabled
| Query string when search is disabled | | prompt
| Prompt before query (>
) | | pointer
| Pointer to the current line (>
) |
-
component
specifies the component (fg
/bg
) from which to extract the color when considering each of the following highlight groups -
group1 [, group2, ...]
is a list of highlight groups that are searched (in order) for a matching color definition
For example, consider the following specification:
'prompt': ['fg', 'Conditional', 'Comment'],
This means we color the prompt - using the fg
attribute of the Conditional
if it exists, - otherwise use the fg
attribute of the Comment
highlight group if it exists, - otherwise fall back to the default color settings for the prompt.
You can examine the color option generated according the setting by printing the result of fzf#wrap()
function like so:
:echo fzf#wrap()
fzf#run
¶ ↑
fzf#run()
function is the core of Vim integration. It takes a single dictionary argument, a spec, and starts fzf process accordingly. At the very least, specify sink
option to tell what it should do with the selected entry.
call fzf#run({'sink': 'e'})
We haven't specified the source
, so this is equivalent to starting fzf on command line without standard input pipe; fzf will use find command (or $FZF_DEFAULT_COMMAND
if defined) to list the files under the current directory. When you select one, it will open it with the sink, :e
command. If you want to open it in a new tab, you can pass :tabedit
command instead as the sink.
call fzf#run({'sink': 'tabedit'})
Instead of using the default find command, you can use any shell command as the source. The following example will list the files managed by git. It's equivalent to running git ls-files | fzf
on shell.
call fzf#run({'source': 'git ls-files', 'sink': 'e'})
fzf options can be specified as options
entry in spec dictionary.
call fzf#run({'sink': 'tabedit', 'options': '--multi --reverse'})
You can also pass a layout option if you don't want fzf window to take up the entire screen.
" up / down / left / right / window are allowed call fzf#run({'source': 'git ls-files', 'sink': 'e', 'left': '40%'}) call fzf#run({'source': 'git ls-files', 'sink': 'e', 'window': '30vnew'})
source
doesn't have to be an external shell command, you can pass a Vim array as the source. In the next example, we pass the names of color schemes as the source to implement a color scheme selector.
call fzf#run({'source': map(split(globpath(&rtp, 'colors/*.vim')), \ 'fnamemodify(v:val, ":t:r")'), \ 'sink': 'colo', 'left': '25%'})
The following table summarizes the available 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 | | sinklist
(or 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 | (Layout) Window position and size (e.g. 20
, 50%
) | | tmux
| string | (Layout) fzf-tmux options (e.g. -p90%,60%
) | | window
(Vim 8 / Neovim) | string | (Layout) Command to open fzf window (e.g. vertical aboveleft 30new
) | | window
(Vim 8 / Neovim) | dict | (Layout) Popup window settings (e.g. {'width': 0.9, 'height': 0.6}
) |
options
entry can be either a string or a list. For simple cases, string should suffice, but prefer to use list type to avoid escaping issues.
call fzf#run({'options': '--reverse --prompt "C:\\Program Files\\"'}) call fzf#run({'options': ['--reverse', '--prompt', 'C:\Program Files\']})
When window
entry is a dictionary, fzf will start in a popup window. The following options are allowed:
-
Required:
-
width
[float range [0 ~ 1]] or [integer range [8 ~ ]] -
height
[float range [0 ~ 1]] or [integer range [4 ~ ]]
-
-
Optional:
-
yoffset
[float default 0.5 range [0 ~ 1]] -
xoffset
[float default 0.5 range [0 ~ 1]] -
relative
[boolean default v:false] -
border
[string defaultrounded
]: Border style-
rounded
/sharp
/horizontal
/vertical
/top
/bottom
/left
/right
/no[ne]

fzf#wrap
¶ ↑
We have seen that several aspects of :FZF
command can be configured with a set of global option variables; different ways to open files (g:fzf_action
), window position and size (g:fzf_layout
), color palette (g:fzf_colors
), etc.
So how can we make our custom fzf#run
calls also respect those variables? Simply by “wrapping” the spec dictionary with fzf#wrap
before passing it to fzf#run
.
-
fzf#wrap([name string], [spec dict], [fullscreen bool]) -> (dict)
-
All arguments are optional. Usually we only need to pass a spec dictionary.
-
name
is for managing history files. It is ignored ifg:fzf_history_dir
is not defined. -
fullscreen
can be either0
or1
(default: 0).
-
fzf#wrap
takes a spec and returns an extended version of it (also a dictionary) with additional options for addressing global preferences. You can examine the return value of it like so:
echo fzf#wrap({'source': 'ls'})
After we “wrap” our spec, we pass it to fzf#run
.
call fzf#run(fzf#wrap({'source': 'ls'}))
Now it supports CTRL-T
, CTRL-V
, and CTRL-X
key bindings (configurable via g:fzf_action
) and it opens fzf window according to g:fzf_layout
setting.
To make it easier to use, let's define LS
command.
command! LS call fzf#run(fzf#wrap({'source': 'ls'}))
Type :LS
and see how it works.
We would like to make :LS!
(bang version) open fzf in fullscreen, just like :FZF!
. Add -bang
to command definition, and use <bang>
value to set the last fullscreen
argument of fzf#wrap
(see :help <bang>
).
" On :LS!, <bang> evaluates to '!', and '!0' becomes 1 command! -bang LS call fzf#run(fzf#wrap({'source': 'ls'}, <bang>0))
Our :LS
command will be much more useful if we can pass a directory argument to it, so that something like :LS /tmp
is possible.
command! -bang -complete=dir -nargs=? LS \ call fzf#run(fzf#wrap({'source': 'ls', 'dir': <q-args>}, <bang>0))
Lastly, if you have enabled g:fzf_history_dir
, you might want to assign a unique name to our command and pass it as the first argument to fzf#wrap
.
" The query history for this command will be stored as 'ls' inside g:fzf_history_dir. " The name is ignored if g:fzf_history_dir is not defined. command! -bang -complete=dir -nargs=? LS \ call fzf#run(fzf#wrap('ls', {'source': 'ls', 'dir': <q-args>}, <bang>0))
Global options supported by fzf#wrap
¶ ↑
-
g:fzf_layout
-
g:fzf_action
-
Works only when no custom
sink
(orsinklist
) is provided-
Having custom sink usually means that each entry is not an ordinary file path (e.g. name of color scheme), so we can't blindly apply the same strategy (i.e.
tabedit some-color-scheme
doesn't make sense)
-
-
-
g:fzf_colors
-
g:fzf_history_dir
Tips¶ ↑
fzf inside terminal buffer¶ ↑
On the latest versions of Vim and Neovim, fzf will start in a terminal buffer. If you find the default ANSI colors to be different, consider configuring the colors using g:terminal_ansi_colors
in regular Vim or g:terminal_color_x
in Neovim.
" Terminal colors for seoul256 color scheme if has('nvim') let g:terminal_color_0 = '#4e4e4e' let g:terminal_color_1 = '#d68787' let g:terminal_color_2 = '#5f865f' let g:terminal_color_3 = '#d8af5f' let g:terminal_color_4 = '#85add4' let g:terminal_color_5 = '#d7afaf' let g:terminal_color_6 = '#87afaf' let g:terminal_color_7 = '#d0d0d0' let g:terminal_color_8 = '#626262' let g:terminal_color_9 = '#d75f87' let g:terminal_color_10 = '#87af87' let g:terminal_color_11 = '#ffd787' let g:terminal_color_12 = '#add4fb' let g:terminal_color_13 = '#ffafaf' let g:terminal_color_14 = '#87d7d7' let g:terminal_color_15 = '#e4e4e4' else let g:terminal_ansi_colors = [ \ '#4e4e4e', '#d68787', '#5f865f', '#d8af5f', \ '#85add4', '#d7afaf', '#87afaf', '#d0d0d0', \ '#626262', '#d75f87', '#87af87', '#ffd787', \ '#add4fb', '#ffafaf', '#87d7d7', '#e4e4e4' \ ] endif
Starting fzf in a popup window¶ ↑
" Required: " - width [float range [0 ~ 1]] or [integer range [8 ~ ]] " - height [float range [0 ~ 1]] or [integer range [4 ~ ]] " " Optional: " - xoffset [float default 0.5 range [0 ~ 1]] " - yoffset [float default 0.5 range [0 ~ 1]] " - relative [boolean default v:false] " - border [string default 'rounded']: Border style " - 'rounded' / 'sharp' / 'horizontal' / 'vertical' / 'top' / 'bottom' / 'left' / 'right' let g:fzf_layout = { 'window': { 'width': 0.9, 'height': 0.6 } }
Alternatively, you can make fzf open in a tmux popup window (requires tmux 3.2 or above) by putting fzf-tmux options in tmux
key.
" See `man fzf-tmux` for available options if exists('$TMUX') let g:fzf_layout = { 'tmux': '-p90%,60%' } else let g:fzf_layout = { 'window': { 'width': 0.9, 'height': 0.6 } } endif
Hide statusline¶ ↑
When fzf starts in a terminal buffer, the file type of the buffer is set to fzf
. So you can set up FileType fzf
autocmd to customize the settings of the window.
For example, if you open fzf on the bottom on the screen (e.g. {'down': '40%'}
), you might want to temporarily disable the statusline for a cleaner look.
let g:fzf_layout = { 'down': '30%' } autocmd! FileType fzf autocmd FileType fzf set laststatus=0 noshowmode noruler \| autocmd BufLeave <buffer> set laststatus=2 showmode ruler
