FZF VIM INTEGRATION *fzf-vim-integration*
|
||
==============================================================================
|
||
|
||
|
||
INSTALLATION *fzf-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}{1}, 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:
|
||
|
||
*fzf#install*
|
||
>
|
||
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }

SUMMARY *fzf-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.
|
||
|
||
1. `fzf#run([spec dict])`
|
||
- Starts fzf inside Vim with the given spec
|
||
- `:call fzf#run({'source': 'ls'})`
|
||
2. `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 to `fzf#run`
|
||
- `:call fzf#run(fzf#wrap({'source': 'ls'}))`
|
||
3. `: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}{2} 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.

Explanation of g:fzf_colors~
|
||
*fzf-explanation-of-gfzfcolors*
|
||
|
||
`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*
|
||
|
||
`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
|
||
`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 default `rounded`]: Border style
|
||
- `rounded` / `sharp` / `horizontal` / `vertical` / `top` / `bottom` / `left` / `right` / `no[ne]`
|
||
|
||
|
||
FZF#WRAP
|
||
==============================================================================
|
||
|
||
*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 if `g:fzf_history_dir`
|
||
is not defined.
|
||
- `fullscreen` can be either `0` or `1` (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 >______________________________________~
|
||
*fzf-global-options-supported-by-fzf#wrap*
|
||
|
||
- `g:fzf_layout`
|
||
- `g:fzf_action`
|
||
- Works only when no custom `sink` (or `sink*`) 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`

*fzf-inside-terminal-buffer*
|

|
||
The latest versions of Vim and Neovim include builtin terminal emulator
|

(`:terminal`) and fzf will start in a terminal buffer in the following cases:
|
||
|
||
- On Neovim
|
||
- On GVim
|
||
- On Terminal Vim with a non-default layout

||
`fzf`. So you can set up `FileType fzf` autocmd to customize the settings of
|
||
the window.
|
||
|
||
For example, if you use a non-popup layout (e.g. `{'down': '40%'}`) on Neovim,
|
||
you might want to temporarily disable the statusline for a cleaner look.
|
||
>
|
||
if has('nvim') && !exists('g:fzf_layout')
|
||
autocmd! FileType fzf
|
||
autocmd FileType fzf set laststatus=0 noshowmode noruler
|
||
\| autocmd BufLeave <buffer> set laststatus=2 showmode ruler
|
||
endif
