FZF Vim integration FZF Vim integration
=================== ===================
This repository only enables basic integration with Vim. If you're looking for Summary
more, check out [fzf.vim](https://github.com/junegunn/fzf.vim) project. -------
(Note: To use fzf in GVim, an external terminal emulator is required.) 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](https://github.com/junegunn/fzf.vim) 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#run` `fzf#run`
--------- ---------
For more advanced uses, you can use `fzf#run([options])` function.
`fzf#run()` function is the core of Vim integration. It takes a single `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 dictionary argument, *a spec*, and starts fzf process accordingly. At the very

entry.
```vim ```vim
call fzf#run({'sink': 'e'}) call fzf#run({'sink': 'e'})
``` ```
Without `source`, fzf will use find command (or `$FZF_DEFAULT_COMMAND` if We haven't specified the `source`, so this is equivalent to starting fzf on
defined) to list the files under the current directory. When you select one, command line without standard input pipe; fzf will use find command (or
it will open it with `:e` command. If you want to open it in a new tab, you `$FZF_DEFAULT_COMMAND` if defined) to list the files under the current
can pass `:tabedit` command instead as the sink. 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.
```vim ```vim
call fzf#run({'sink': 'tabedit'}) 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 Instead of using the default find command, you can use any shell command as
the source. This will list the files managed by git. the source. The following example will list the files managed by git. It's
equivalent to running `git ls-files | fzf` on shell.
```vim ```vim
call fzf#run({'source': 'git ls-files', 'sink': 'e'}) 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. fzf options can be specified as `options` entry in spec dictionary.
```vim
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.
```vim ```vim
" up / down / left / right / window are allowed " 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', 'left': '40%'})
call fzf#run({'source': 'git ls-files', 'sink': 'e', 'window': '30vnew'}) 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 `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 array as the source. In the next example, we pass the names of color

call fzf#run({'source': map(filter(range(1, bufnr('$')), 'buflisted(v:val)'),

```

`fzf#wrap` `fzf#wrap`
---------- ----------
`:FZF` command provided by default knows how to handle `CTRL-T`, `CTRL-X`, and We have seen that several aspects of `:FZF` command can be configured with
`CTRL-V` and opens the selected file in a new tab, in a horizontal split, or a set of global option variables; different ways to open files
in a vertical split respectively. And these key bindings can be configured via (`g:fzf_action`), window position and size (`g:fzf_layout`), color palette
`g:fzf_action`. This is implemented using `--expect` option of fzf and the (`g:fzf_colors`), etc.
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 So how can we make our custom `fzf#run` calls also respect those variables?
`fzf#run`, you can make your command also support the options. 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:
```vim ```vim
" Usage: echo fzf#wrap({'source': 'ls'})
" 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 After we *"wrap"* our spec, we pass it to `fzf#run`.
--------------------------
```vim
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.
```vim
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>`).
```vim
" 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.
```vim
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`.
```vim
" 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))
```

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 We have seen that several aspects of `:FZF` command can be configured with a
`fzf#run`, you can make your command also support the options. 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:
> >
" Usage: echo fzf#wrap({'source': 'ls'})
" fzf#wrap([name string,] [opts dict,] [fullscreen boolean]) <
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.
" This command now supports CTRL-T, CTRL-V, and CTRL-X key bindings To make it easier to use, let's define `LS` command.
" and opens fzf according to g:fzf_layout setting. >
command! Buffers call fzf#run(fzf#wrap( command! LS call fzf#run(fzf#wrap({'source': 'ls'}))
\ {'source': map(range(1, bufnr('$')), 'bufname(v:val)')})) <
Type `:LS` and see how it works.
" This extends the above example to open fzf in fullscreen We would like to make `:LS!` (bang version) open fzf in fullscreen, just like
" when the command is run with ! suffix (Buffers!) `:FZF!`. Add `-bang` to command definition, and use <bang> value to set the
command! -bang Buffers call fzf#run(fzf#wrap( last `fullscreen` argument of `fzf#wrap` (see :help <bang>).
\ {'source': map(range(1, bufnr('$')), 'bufname(v:val)')}, <bang>0)) >
" On :LS!, <bang> evaluates to '!', and '!0' becomes 1
" You can optionally pass the name of the command as the first argument to command! -bang LS call fzf#run(fzf#wrap({'source': 'ls'}, <bang>0))
" fzf#wrap to make it work with g:fzf_history_dir <
command! -bang Buffers call fzf#run(fzf#wrap('buffers', Our `:LS` command will be much more useful if we can pass a directory argument
\ {'source': map(range(1, bufnr('$')), 'bufname(v:val)')}, <bang>0)) 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))
