For more advanced uses, you can use `fzf#run([options])` function with the
following options.
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.
```vim
call fzf#run({'sink': 'e'})
```
Without `source`, fzf will use find command (or `$FZF_DEFAULT_COMMAND` if
defined) to list the files under the current directory. When you select one,
it will open it with `:e` command. If you want to open it in a new tab, you
can pass `:tabedit` command instead as the sink.
```vim
call fzf#run({'sink': 'tabedit'})
```
fzf allows you to select multiple entries with `--multi` (or `-m`) option, and
you can change its bottom-up layout with `--reverse` option. Such options can
be specified as `options`.
```vim
call fzf#run({'sink': 'tabedit', 'options': '--multi --reverse'})
```
Instead of using the default find command, you can use any shell command as
the source. This will list the files managed by git.
```vim
call fzf#run({'source': 'git ls-files', 'sink': 'e'})
```
Pass a layout option if you don't want fzf window to take up the entire screen.
```vim
" up / down / left / right / window are allowed
call fzf#run({'source': 'git ls-files', 'sink': 'e', 'right': '40%'})
call fzf#run({'source': 'git ls-files', 'sink': 'e', 'window': '30vsplit'})
```
`source` doesn't have to be an external shell command, you can pass a Vim
array as the source. In the following example, we use the names of the open
buffers as the source.
```vim
call fzf#run({'source': map(filter(range(1, bufnr('$')), 'buflisted(v:val)'),
\ 'bufname(v:val)'),
\ 'sink': 'e', 'down': '30%'})
```
Or the names of color schemes.
```vim
call fzf#run({'source': map(split(globpath(&rtp, 'colors/*.vim')),
\ 'fnamemodify(v:val, ":t:r")'),
\ 'sink': 'colo', 'left': '25%'})
```

`fzf#wrap`
----------
`fzf#wrap([name string,] [opts dict,] [fullscreen boolean])` is a helper
function that decorates the options dictionary so that it understands
`g:fzf_layout`, `g:fzf_action`, `g:fzf_colors`, and `g:fzf_history_dir` like
`:FZF`.
`: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.
```vim
command! -bang MyStuff
\ call fzf#run(fzf#wrap('my-stuff', {'dir': '~/my-stuff'}, <bang>0))
" 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))
