FZF VIM INTEGRATION *fzf-vim-integration*
==============================================================================
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}{1} 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[!]
==============================================================================
*: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}{2}, 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.

*g:fzf_action* *g:fzf_layout* *g:fzf_colors* *g:fzf_history_dir*
- `g:fzf_action`
- Customizable extra key bindings for opening selected files in different

\ 'header': ['fg', 'Comment'] }
" Enable per-command history
" - History files will be stored in the specified directory
" - When set, CTRL-N and CTRL-P will be bound to 'next-history' and
" 'previous-history' instead of 'down' and 'up'.
let g:fzf_history_dir = '~/.local/share/fzf-history'
<
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%` )
`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]]
- `height` [float range [0 ~ 1]]
- Optional:
- `xoffset` [float default 0.0 range [0 ~ 1]]
- `yoffset` [float default 0.0 range [0 ~ 1]]
- `highlight` [string default `'Comment'`]: Highlight group for border
- `rounded` [boolean default `v:true`]: Use rounded border
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 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))
<
TIPS *fzf-tips*
==============================================================================
< fzf inside terminal buffer >________________________________________________~
*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
- `call fzf#run({'left': '30%'})` or `let g:fzf_layout = {'left': '30%'}`
Starting fzf in a popup window~
*fzf-starting-fzf-in-a-popup-window*
>
" Required:
" - width [float range [0 ~ 1]]
" - height [float range [0 ~ 1]]
"
" Optional:
" - xoffset [float default 0.5 range [0 ~ 1]]
" - yoffset [float default 0.5 range [0 ~ 1]]
" - highlight [string default 'Comment']: Highlight group for border
" - rounded [boolean default v:true]: Use rounded border
let g:fzf_layout = { 'window': { 'width': 0.9, 'height': 0.6 } }
<
Hide statusline~
*fzf-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 use the default layout (`{'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
