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.

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.

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)
`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
`prompt` | Prompt before query ( `> ` )
----------------------+------------------------------------------------------
- `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]]
- `height` [float range [0 ~ 1]]
- Optional:
- `yoffset` [float default 0.5 range [0 ~ 1]]
- `xoffset` [float default 0.5 range [0 ~ 1]]
- `highlight` [string default `'Comment'`]: Highlight group for border
- `border` [string default `rounded`]: Border style
- `rounded` / `sharp` / `horizontal` / `vertical` / `top` / `bottom` / `left` / `right`
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
" - 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~
*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
