FZF VIM INTEGRATION *fzf-vim-integration*
==============================================================================
This repository only enables basic integration with Vim. If you're looking for
more, check out {fzf.vim}{1} project.
(Note: To use fzf in GVim, an external terminal emulator is required.)
{1} https://github.com/junegunn/fzf.vim
:FZF[!]
==============================================================================
*: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}{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.

FZF#RUN *fzf#run*
==============================================================================
2019-06-08 14:17:30 +00:00
For more advanced uses, you can use `fzf#run([options])` function.
`fzf#run()` function is the core of Vim integration. It takes a single
dictionary argument. At the very least, specify `sink` option to tell what it
should do with the selected entry.
>
call fzf#run({'sink': 'e'})
<
Without `source`, fzf will use find command (or `$FZF_DEFAULT_COMMAND` if
defined) to list the files under the current directory. When you select one,
it will open it with `:e` command. If you want to open it in a new tab, you
can pass `:tabedit` command instead as the sink.
>
call fzf#run({'sink': 'tabedit'})
<
fzf allows you to select multiple entries with `--multi` (or `-m`) option, and
you can change its bottom-up layout with `--reverse` option. Such options can
be specified as `options`.
>
call fzf#run({'sink': 'tabedit', 'options': '--multi --reverse'})
<
Instead of using the default find command, you can use any shell command as
the source. This will list the files managed by git.
>
call fzf#run({'source': 'git ls-files', 'sink': 'e'})
<
Pass a layout option if you don't want fzf window to take up the entire
screen.
>
" up / down / left / right / window are allowed
call fzf#run({'source': 'git ls-files', 'sink': 'e', 'right': '40%'})
2019-06-08 14:29:04 +00:00
call fzf#run({'source': 'git ls-files', 'sink': 'e', 'window': '30vnew'})
2019-06-08 14:17:30 +00:00
<
`source` doesn't have to be an external shell command, you can pass a Vim
array as the source. In the following example, we use the names of the open
buffers as the source.
>
call fzf#run({'source': map(filter(range(1, bufnr('$')), 'buflisted(v:val)'),
\ 'bufname(v:val)'),
\ 'sink': 'e', 'down': '30%'})
<
Or the names of color schemes.
>
call fzf#run({'source': map(split(globpath(&rtp, 'colors/*.vim')),
\ 'fnamemodify(v:val, ":t:r")'),
\ 'sink': 'colo', 'left': '25%'})
<
The following table shows the available options.
2017-04-01 03:00:30 +00:00
---------------------------+---------------+--------------------------------------------------------------
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
2017-04-01 03:00:30 +00:00
`dir` | string | Working directory
`up` / `down` / `left` / `right` | number/string | Use tmux pane with the given size (e.g. `20` , `50%` )
`window` (Vim 8 / Neovim) | string | Command to open fzf window (e.g. `verticalaboveleft30new` )
2017-04-01 03:00:30 +00:00
`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\\"'})

FZF#WRAP *fzf#wrap*
==============================================================================
2019-06-08 14:17:30 +00:00
`:FZF` command provided by default knows how to handle CTRL-T, CTRL-X, and
CTRL-V and opens the selected file in a new tab, in a horizontal split, or in
a vertical split respectively. And these key bindings can be configured via
`g:fzf_action`. This is implemented using `--expect` option of fzf and the
smart sink function. It also understands `g:fzf_colors`, `g:fzf_layout` and
`g:fzf_history_dir`. However, `fzf#run` doesn't know about any of these
options.
By "wrapping" your options dictionary with `fzf#wrap` before passing it to
`fzf#run`, you can make your command also support the options.

2019-06-08 14:17:30 +00:00
" Usage:
" fzf#wrap([name string,] [opts dict,] [fullscreen boolean])
" This command now supports CTRL-T, CTRL-V, and CTRL-X key bindings
" and opens fzf according to g:fzf_layout setting.
command! Buffers call fzf#run(fzf#wrap(
\ {'source': map(range(1, bufnr('$')), 'bufname(v:val)')}))
" This extends the above example to open fzf in fullscreen
" when the command is run with ! suffix (Buffers!)
command! -bang Buffers call fzf#run(fzf#wrap(
\ {'source': map(range(1, bufnr('$')), 'bufname(v:val)')}, <bang>0))
" You can optionally pass the name of the command as the first argument to
" fzf#wrap to make it work with g:fzf_history_dir
command! -bang Buffers call fzf#run(fzf#wrap('buffers',
\ {'source': map(range(1, bufnr('$')), 'bufname(v:val)')}, <bang>0))

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 the non-default layout
- `callfzf#run({'left':'30%'})` or `letg:fzf_layout={'left':'30%'}`
< Hide statusline >___________________________________________________________~
*fzf-hide-statusline*
When fzf starts in a terminal buffer, you may want to hide the statusline of
the containing buffer.
>
autocmd! FileType fzf
autocmd FileType fzf set laststatus=0 noshowmode noruler
\| autocmd BufLeave <buffer> set laststatus=2 showmode ruler
