### Windows packages

On Windows, fzf is available via [Chocolatey][choco], [Scoop][scoop],
[Winget][winget], and [MSYS2][msys2]:

| Package manager | Command                               |
| --------------- | ------------------------------------- |
| Chocolatey      | `choco install fzf`                   |
| Scoop           | `scoop install fzf`                   |
| Winget          | `winget install fzf`                  |
| MSYS2 (pacman)  | `pacman -S $MINGW_PACKAGE_PREFIX-fzf` |

[choco]: https://chocolatey.org/packages/fzf
[scoop]: https://github.com/ScoopInstaller/Main/blob/master/bucket/fzf.json
[winget]: https://github.com/microsoft/winget-pkgs/tree/master/manifests/j/junegunn/fzf
[msys2]: https://packages.msys2.org/base/mingw-w64-fzf

### Using git

Alternatively, you can "git clone" this repository to any directory and run
[install](https://github.com/junegunn/fzf/blob/master/install) script.

```sh
git clone --depth 1 https://github.com/junegunn/fzf.git ~/.fzf
~/.fzf/install
```

The install script will add lines to your shell configuration file to modify
`$PATH` and set up shell integration.

### Binary releases

You can download the official fzf binaries from the releases page.

* https://github.com/junegunn/fzf/releases

### Setting up shell integration

Add the following line to your shell configuration file.

* bash
  ```sh
  # Set up fzf key bindings and fuzzy completion
  eval "$(fzf --bash)"
  ```
* zsh
  ```sh
  # Set up fzf key bindings and fuzzy completion
  source <(fzf --zsh)
  ```
* fish
  ```fish
  # Set up fzf key bindings
  fzf --fish | source
  ```
* Nushell -- Nushell does not support piping into `source`, so the install
  script generates a file in the autoload directory. If you didn't use the
  install script, you can manually set it up:
  ```nu
  # Generate the integration script
  mkdir ($nu.default-config-dir | path join "autoload")
  fzf --nushell | save -f ($nu.default-config-dir | path join "autoload" "_fzf_integration.nu")
  ```

> [!NOTE]
> `--bash`, `--zsh`, `--fish`, and `--nushell` options are only available in
> recent versions of fzf. If you have an older version of fzf, or want finer control, you can
> source individual script files in the [/shell](/shell) directory. The
> location of the files may vary depending on the package manager you use.
> Please refer to the package documentation for more information.
> (e.g. `apt show fzf`)

> [!TIP]
> You can disable CTRL-T, CTRL-R, or ALT-C bindings by setting the
> corresponding `*_COMMAND` variable to an empty string when sourcing the
> script. For example, to disable CTRL-R and ALT-C:
>
> * bash: `FZF_CTRL_R_COMMAND= FZF_ALT_C_COMMAND= eval "$(fzf --bash)"`
> * zsh: `FZF_CTRL_R_COMMAND= FZF_ALT_C_COMMAND= source <(fzf --zsh)`
> * fish: `fzf --fish | FZF_CTRL_R_COMMAND= FZF_ALT_C_COMMAND= source`
> * nushell: add to your `env.nu`:
>   `$env.FZF_CTRL_R_COMMAND = ""; $env.FZF_ALT_C_COMMAND = ""`
>
> Setting the variables after sourcing the script will have no effect.

### Vim/Neovim plugin

If you use [vim-plug](https://github.com/junegunn/vim-plug), add this to
your Vim configuration file:

```vim
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
Plug 'junegunn/fzf.vim'
```

* `junegunn/fzf` provides the basic library functions
    * `fzf#install()` makes sure that you have the latest binary
* `junegunn/fzf.vim` is [a separate project](https://github.com/junegunn/fzf.vim)
  that provides a variety of useful commands

To learn more about the Vim integration, see [README-VIM.md](README-VIM.md).

> [!TIP]
> If you use Neovim and prefer Lua-based plugins, check out
> [fzf-lua](https://github.com/ibhagwan/fzf-lua).

Upgrading fzf
-------------

fzf is being actively developed, and you might want to upgrade it once in a
while. Please follow the instruction below depending on the installation
method used.

- git: `cd ~/.fzf && git pull && ./install`
- brew: `brew update; brew upgrade fzf`
- macports: `sudo port upgrade fzf`
- chocolatey: `choco upgrade fzf`
- vim-plug: `:PlugUpdate fzf`

Building fzf
------------

See [BUILD.md](BUILD.md).

Usage
-----

fzf will launch interactive finder, read the list from STDIN, and write the
selected item to STDOUT.

```sh
find * -type f | fzf > selected
```

Without STDIN pipe, fzf will traverse the file system under the current
directory to get the list of files.

```sh
vim $(fzf)
```

> [!NOTE]
> You can override the default behavior
> * Either by setting `$FZF_DEFAULT_COMMAND` to a command that generates the desired list
> * Or by setting `--walker`, `--walker-root`, and `--walker-skip` options in `$FZF_DEFAULT_OPTS`

> [!WARNING]
> A more robust solution would be to use `xargs` but we've presented
> the above as it's easier to grasp
> ```sh
> fzf --print0 | xargs -0 -o vim
> ```

> [!TIP]
> fzf also has the ability to turn itself into a different process.
>
> ```sh
> fzf --bind 'enter:become(vim {})'
> ```
>
> *See [Turning into a different process](#turning-into-a-different-process)
> for more information.*

### Using the finder

- `CTRL-K` / `CTRL-J` (or `CTRL-P` / `CTRL-N`) to move cursor up and down
- `Enter` key to select the item, `CTRL-C` / `CTRL-G` / `ESC` to exit
- On multi-select mode (`-m`), `TAB` and `Shift-TAB` to mark multiple items
- Emacs style key bindings
- Mouse: scroll, click, double-click; shift-click and shift-scroll on
  multi-select mode

### Display modes

fzf by default runs in fullscreen mode, but there are other display modes.

#### `--height` mode

With `--height HEIGHT[%]`, fzf will start below the cursor with the given height.

```sh
fzf --height 40%
```

`reverse` layout and `--border` goes well with this option.

```sh
fzf --height 40% --layout reverse --border
```

By prepending `~` to the height, you're setting the maximum height.

```sh
# Will take as few lines as possible to display the list
seq 3 | fzf --height ~100%
seq 3000 | fzf --height ~100%
```

Height value can be a negative number.

```sh
# Screen height - 3
fzf --height -3
```

#### `--popup` mode

With `--popup` option, fzf will start in a popup window
(requires tmux 3.3+ or Zellij 0.44+).

```sh
# --popup [center|top|bottom|left|right][,SIZE[%]][,SIZE[%][,border-native]]

fzf --popup center         # Center, 50% width and height
fzf --popup 80%            # Center, 80% width and height
fzf --popup 100%,50%       # Center, 100% width and 50% height
fzf --popup left,40%       # Left, 40% width
fzf --popup left,40%,90%   # Left, 40% width, 90% height
fzf --popup top,40%        # Top, 40% height
fzf --popup bottom,80%,40% # Bottom, 80% width, 40% height
```

`--popup` is silently ignored when you're not on tmux or Zellij.

> [!NOTE]
> If you're stuck with an old version of tmux that doesn't support popup,
> or if you want to open fzf in a regular tmux pane, check out
> [fzf-tmux](bin/fzf-tmux) script.

> [!TIP]
> You can add these options to `$FZF_DEFAULT_OPTS` so that they're applied by
> default. For example,
>
> ```sh
> # Open in a popup if on tmux or Zellij, otherwise use --height mode
> export FZF_DEFAULT_OPTS='--height 40% --popup bottom,40% --layout reverse --border top'
> ```

### Search syntax

Unless otherwise specified, fzf starts in "extended-search mode" where you can
type in multiple search terms delimited by spaces. e.g. `^music .mp3$ sbtrkt
!fire`

| Token     | Match type                              | Description                                  |
| --------- | --------------------------------------  | ------------------------------------------   |
| `sbtrkt`  | fuzzy-match                             | Items that match `sbtrkt`                    |
| `'wild`   | exact-match (quoted)                    | Items that include `wild`                    |
| `'wild'`  | exact-boundary-match (quoted both ends) | Items that include `wild` at word boundaries |
| `^music`  | prefix-exact-match                      | Items that start with `music`                |
| `.mp3$`   | suffix-exact-match                      | Items that end with `.mp3`                   |
| `!fire`   | inverse-exact-match                     | Items that do not include `fire`             |
| `!^music` | inverse-prefix-exact-match              | Items that do not start with `music`         |
| `!.mp3$`  | inverse-suffix-exact-match              | Items that do not end with `.mp3`            |

If you don't prefer fuzzy matching and do not wish to "quote" every word,
start fzf with `-e` or `--exact` option. Note that when  `--exact` is set,
`'`-prefix "unquotes" the term.

A single bar character term acts as an OR operator. For example, the following
query matches entries that start with `core` and end with either `go`, `rb`,
or `py`.

```
^core go$ | rb$ | py$
```

### Environment variables

- `FZF_DEFAULT_COMMAND`
    - Default command to use when input is tty
    - e.g. `export FZF_DEFAULT_COMMAND='fd --type f'`
- `FZF_DEFAULT_OPTS`
    - Default options
    - e.g. `export FZF_DEFAULT_OPTS="--layout=reverse --inline-info"`
- `FZF_DEFAULT_OPTS_FILE`
    - If you prefer to manage default options in a file, set this variable to
      point to the location of the file
    - e.g. `export FZF_DEFAULT_OPTS_FILE=~/.fzfrc`

> [!WARNING]
> `FZF_DEFAULT_COMMAND` is not used by shell integration due to the
> slight difference in requirements.
>
> * `CTRL-T` runs `$FZF_CTRL_T_COMMAND` to get a list of files and directories
> * `ALT-C` runs `$FZF_ALT_C_COMMAND` to get a list of directories
> * `vim ~/**<tab>` runs `fzf_compgen_path()` with the prefix (`~/`) as the first argument
> * `cd foo**<tab>` runs `fzf_compgen_dir()` with the prefix (`foo`) as the first argument
>
> The available options are described later in this document.

### Customizing the look

The user interface of fzf is fully customizable with a large number of
configuration options. For a quick setup, you can start with one of the style
presets -- `default`, `full`, or `minimal` -- using the `--style` option.

```sh
fzf --style full \
    --preview 'fzf-preview.sh {}' --bind 'focus:transform-header:file --brief {}'
```

| Preset    | Screenshot                                                                             |
| :---      | :---                                                                                   |
| `default` | <img src="https://raw.githubusercontent.com/junegunn/i/master/fzf-style-default.png"/> |
| `full`    | <img src="https://raw.githubusercontent.com/junegunn/i/master/fzf-style-full.png"/>    |
| `minimal` | <img src="https://raw.githubusercontent.com/junegunn/i/master/fzf-style-minimal.png"/> |

Here's an example based on the `full` preset:

<img src="https://raw.githubusercontent.com/junegunn/i/master/fzf-4-borders.png"/>

<details>

```sh
git ls-files | fzf --style full \
    --border --padding 1,2 \
    --border-label ' Demo ' --input-label ' Input ' --header-label ' File Type ' \
    --preview 'fzf-preview.sh {}' \
    --bind 'result:transform-list-label:
        if [[ -z $FZF_QUERY ]]; then
          echo " $FZF_MATCH_COUNT items "
        else
          echo " $FZF_MATCH_COUNT matches for [$FZF_QUERY] "
        fi
        ' \
    --bind 'focus:transform-preview-label:[[ -n {} ]] && printf " Previewing [%s] " {}' \
    --bind 'focus:+transform-header:file --brief {} || echo "No file selected"' \
    --bind 'ctrl-r:change-list-label( Reloading the list )+reload(sleep 2; git ls-files)' \
    --color 'border:#aaaaaa,label:#cccccc' \
    --color 'preview-border:#9999cc,preview-label:#ccccff' \
    --color 'list-border:#669966,list-label:#99cc99' \
    --color 'input-border:#996666,input-label:#ffcccc' \
    --color 'header-border:#6699cc,header-label:#99ccff'
```

</details>

Key bindings for command-line
-----------------------------

By [setting up shell integration](#setting-up-shell-integration), you can use
the following key bindings in bash, zsh, fish, and Nushell.

- `CTRL-T` - Paste the selected files and directories onto the command-line
    - The list is generated using `--walker file,dir,follow,hidden` option
        - You can override the behavior by setting `FZF_CTRL_T_COMMAND` to a custom command that generates the desired list
        - Or you can set `--walker*` options in `FZF_CTRL_T_OPTS`
    - Set `FZF_CTRL_T_OPTS` to pass additional options to fzf
      ```sh
      # Preview file content using bat (https://github.com/sharkdp/bat)
      export FZF_CTRL_T_OPTS="
        --walker-skip .git,node_modules,target
        --preview 'bat -n --color=always {}'
        --bind 'ctrl-/:change-preview-window(down|hidden|)'"
      ```
    - Can be disabled by setting `FZF_CTRL_T_COMMAND` to an empty string when
      sourcing the script
- `CTRL-R` - Paste the selected command from history onto the command-line.
    - Select multiple commands with `TAB`.
    - If you want to see the commands in chronological order, press `CTRL-R`
      again which toggles sorting by relevance
    - Press `ALT-R` to toggle "raw" mode where you can see the surrounding items
      of a match. In this mode, you can press `CTRL-N` and `CTRL-P` to move
      between the matching items only.
    - Press `CTRL-/` or `ALT-/` to toggle line wrapping
    - Press `SHIFT-DELETE` to delete the selected commands (bash and fish)
    - Fish shell only:
      - Press `ALT-ENTER` to reformat and insert the selected commands
      - Press `ALT-T` to cycle through command prefix (timestamp, date/time, none)
    - Set `FZF_CTRL_R_OPTS` to pass additional options to fzf
      ```sh
      # CTRL-Y to copy the command into clipboard using pbcopy
      export FZF_CTRL_R_OPTS="
        --bind 'ctrl-y:execute-silent(echo -n {2..} | pbcopy)+abort'
        --color header:italic
        --header 'Press CTRL-Y to copy command into clipboard'"
      ```
      ```fish
      # Fish shell: Set date/time as default prefix
      set -gx FZF_CTRL_R_OPTS "--with-nth 1,3.. --bind 'alt-t:change-with-nth(2..|3..|1,3..)'"

      # Or display no prefix by default
      set -gx FZF_CTRL_R_OPTS "--with-nth 3.. --bind 'alt-t:change-with-nth(2..|1,3..|3..)'"
      ```
    - Can be disabled by setting `FZF_CTRL_R_COMMAND` to an empty string when
      sourcing the script
    - Custom override via a non-empty `FZF_CTRL_R_COMMAND` is not yet supported and will emit a warning
- `ALT-C` - cd into the selected directory
    - The list is generated using `--walker dir,follow,hidden` option
    - Set `FZF_ALT_C_COMMAND` to override the default command
        - Or you can set `--walker-*` options in `FZF_ALT_C_OPTS`
    - Set `FZF_ALT_C_OPTS` to pass additional options to fzf
      ```sh
      # Print tree structure in the preview window
      export FZF_ALT_C_OPTS="
        --walker-skip .git,node_modules,target
        --preview 'tree -C {}'"
      ```
    - Can be disabled by setting `FZF_ALT_C_COMMAND` to an empty string when
      sourcing the script

Display modes for these bindings can be separately configured via
`FZF_{CTRL_T,CTRL_R,ALT_C}_OPTS` or globally via `FZF_DEFAULT_OPTS`.
(e.g. `FZF_CTRL_R_OPTS='--popup bottom,60% --height 60% --border top'`)

Fuzzy completion
----------------

Shell integration also provides fuzzy completion for bash, zsh, fish, and Nushell.

### Files and directories

Fuzzy completion for files and directories can be triggered if the word before
the cursor ends with the trigger sequence, which is by default `**`.

- `COMMAND [DIRECTORY/][FUZZY_PATTERN]**<TAB>`

```sh
# Files under the current directory
# - You can select multiple items with TAB key
vim **<TAB>

# Files under parent directory
vim ../**<TAB>

# Files under parent directory that match `fzf`
vim ../fzf**<TAB>

# Files under your home directory
vim ~/**<TAB>


# Directories under current directory (single-selection)
cd **<TAB>

# Directories under ~/github that match `fzf`
cd ~/github/fzf**<TAB>
```

### Process IDs

Fuzzy completion for PIDs is provided for kill command.

```sh
# Can select multiple processes with <TAB> or <Shift-TAB> keys
kill -9 **<TAB>
```

### Host names

For ssh command, fuzzy completion for hostnames is provided. The names are
extracted from /etc/hosts and ~/.ssh/config.

```sh
ssh **<TAB>
```

### Environment variables / Aliases

```sh
# bash and zsh
unset **<TAB>
export **<TAB>
unalias **<TAB>

# fish
set <SHIFT-TAB>
```

### Customizing fuzzy completion for bash and zsh

#### Customizing fzf options for completion

```sh
# Use ~~ as the trigger sequence instead of the default **
export FZF_COMPLETION_TRIGGER='~~'

# Options to fzf command
export FZF_COMPLETION_OPTS='--border --info=inline'

# Options for path completion (e.g. vim **<TAB>)
export FZF_COMPLETION_PATH_OPTS='--walker file,dir,follow,hidden'

# Options for directory completion (e.g. cd **<TAB>)
export FZF_COMPLETION_DIR_OPTS='--walker dir,follow'

# Advanced customization of fzf options via _fzf_comprun function
# - The first argument to the function is the name of the command.
# - You should make sure to pass the rest of the arguments ($@) to fzf.
_fzf_comprun() {
  local command=$1
  shift

  case "$command" in
    cd)           fzf --preview 'tree -C {} | head -200'   "$@" ;;
    export|unset) fzf --preview "eval 'echo \$'{}"         "$@" ;;
    ssh)          fzf --preview 'dig {}'                   "$@" ;;
    *)            fzf --preview 'bat -n --color=always {}' "$@" ;;
  esac
}
```

#### Customizing completion source for paths and directories

```sh
# Use fd (https://github.com/sharkdp/fd) for listing path candidates.
# - The first argument to the function ($1) is the base path to start traversal
# - See the source code (completion.{bash,zsh}) for the details.
_fzf_compgen_path() {
  fd --hidden --follow --exclude ".git" . "$1"
}

# Use fd to generate the list for directory completion
_fzf_compgen_dir() {
  fd --type d --hidden --follow --exclude ".git" . "$1"
}
```

#### Supported commands (bash)

On bash, fuzzy completion is enabled only for a predefined set of commands
(`complete | grep _fzf` to see the list). But you can enable it for other
commands as well by using `_fzf_setup_completion` helper function.

```sh
# usage: _fzf_setup_completion path|dir|var|alias|host COMMANDS...
_fzf_setup_completion path ag git kubectl
_fzf_setup_completion dir tree
```

#### Custom fuzzy completion

_**(Custom completion API is experimental and subject to change)**_

For a command named _"COMMAND"_, define `_fzf_complete_COMMAND` function using
`_fzf_complete` helper.

```sh
# Custom fuzzy completion for "doge" command
#   e.g. doge **<TAB>
_fzf_complete_doge() {
  _fzf_complete --multi --reverse --prompt="doge> " -- "$@" < <(
    echo very
    echo wow
    echo such
    echo doge
  )
}
```

- The arguments before `--` are the options to fzf.
- After `--`, simply pass the original completion arguments unchanged (`"$@"`).
- Then, write a set of commands that generates the completion candidates and
  feed its output to the function using process substitution (`< <(...)`).

zsh will automatically pick up the function using the naming convention but in
bash you have to manually associate the function with the command using the
`complete` command.

```sh
[ -n "$BASH" ] && complete -F _fzf_complete_doge -o default -o bashdefault doge
```

If you need to post-process the output from fzf, define
`_fzf_complete_COMMAND_post` as follows.

```sh
_fzf_complete_foo() {
  _fzf_complete --multi --reverse --header-lines=3 -- "$@" < <(
    ls -al
  )
}

_fzf_complete_foo_post() {
  awk '{print $NF}'
}

[ -n "$BASH" ] && complete -F _fzf_complete_foo -o default -o bashdefault foo
```

### Fuzzy completion for fish

Fuzzy completion for fish differs from bash and zsh in that:

- It doesn't require a trigger sequence like `**`. Instead, if activates
  on `Shift-TAB` (replacing the native pager search mode), while `TAB` preserves
  fish's native completion behavior.
- It relies on fish's native completion system to populate the candidate list,
  rather than performing a recursive file system traversal. For recursive
  searching, use the `CTRL-T` binding instead.
- If the current command line token is a wildcard pattern, it performs search on
  the wildcard expansion path list (instead of the native behavior of inserting
  all the results in command line). Because the shell is used for the expansion,
  there is a limit in the number of results.
- The only supported configuration variables are `FZF_COMPLETION_OPTS` and
  `FZF_EXPANSION_OPS`.
- The function that is used by custom completion functions is named
  `fzf_complete`, which only accepts fzf options as arguments, and can be also
  called without any redirected input, to just modify fzf options while
  presenting the native completion results. For compatibility with other shells,
  a function named `_fzf_complete` is provided, that can accept ` -- $argv` in
  its command line arguments, after fzf options.

For commands that are not covered by fish completions, it is better to create
regular fish completion functions (which will work for both `TAB` and
`Shift-TAB`), and create fzf completion functions only when needing to modify
fzf options for a specific command or want different results for `Shift-TAB`:

```fish
# Customize git completion
function _fzf_complete_git
  # Show header text with active branch for all git completions
  set -lx -- FZF_COMPLETION_OPTS --header="'"(git branch --show-current 2>/dev/null)"'"

  # No other changes when less than 3 arguments, or when completing options
  if not set -q argv[3]; or string match -q -- '-*' $argv[-1]
    fzf_complete
    return
  end

  # Check subcommand
  switch $argv[2]
    case checkout diff log show
      # Set preview and display all branches and commits for subcommands: checkout, diff, log, show
      begin
        git branch --all --format='%(refname:short)'
        git log --all --oneline --color=always
      end | fzf_complete --no-multi --ansi --accept-nth=1 --query=$argv[-1] --preview='git show --color=always {1}'

    case add rm mv
      # Only set preview for subcommands: add, rm, mv
      # Special characters in fish completion lists are escaped, so the r flag must be used.
      fzf_complete --preview="git diff --color=always {r1}"

    case '*'
      # No changes for other subcommands
      fzf_complete
  end
end
```

Similar to bash and zsh, the output of fzf can be processed before inserted in
command line, by defining a function named `_fzf_complete_COMMAND_post` or
`_fzf_post_complete_COMMAND`:

```fish
function _fzf_complete_foo
  ls -sh --zero --color=always | fzf_complete --read0 --print0 --ansi --no-multi-line --header-lines=1
end

function _fzf_post_complete_foo
  while read -lz result
    string escape -n -- $result | string trim -l -c '\ ' | string split -m 1 -f 2 ' '
  end
end
```

### Fuzzy completion for Nushell

Fuzzy completion in Nushell works via the
[external completer](https://www.nushell.sh/cookbook/external_completers.html)
mechanism. There are some differences compared to bash and zsh:

- On Nushell >= 0.103.0, the external completer is no longer called for
  built-in commands (e.g. `cd`, `ls`). Fuzzy completion with `**<TAB>` only
  works for external commands.
- Custom completers can be defined via the `$env.FZF_COMPLETERS` record in
  your `config.nu`. Each entry is a closure that receives the prefix and the
  command spans, and returns either a list of candidate strings or a record
  `{ candidates: [...], opts: [...] }` for custom fzf options:
  ```nu
  $env.FZF_COMPLETERS = {
      pacman: {|prefix, spans|
          let sub = $spans | skip 1 | first
          let candidates = (if ($sub =~ "-[SF]") { ^pacman -Slq | lines
          } else if ($sub =~ "-[QR]") { ^pacman -Qq | lines
          } else { [] })
          { candidates: $candidates, opts: ["--preview", "pacman -Si {}"] }
      }
  }
  ```
  See [shell/completion-examples.nu](shell/completion-examples.nu) for more
  examples.
- The following environment variables are supported:
  `FZF_COMPLETION_TRIGGER`, `FZF_COMPLETION_OPTS`,
  `FZF_COMPLETION_PATH_OPTS`, `FZF_COMPLETION_DIR_OPTS`,
  `FZF_COMPLETION_DIR_COMMANDS`.

### Customizing for different types of input

Since fzf is a general-purpose text filter, its algorithm was designed to
"generally" work well with any kind of input. However, admittedly, there is no
true one-size-fits-all solution, and you may want to tweak the algorithm and
some of the settings depending on the type of the input. To make this process
easier, fzf provides a set of "scheme"s for some common input types.

| Scheme             | Description                                                                         |
| :---               | :---                                                                                |
| `--scheme=default` | Generic scheme designed to work well with any kind of input                         |
| `--scheme=path`    | Suitable for file paths                                                             |
| `--scheme=history` | Suitable for command history or any input where chronological ordering is important |

(See `fzf --man` for the details)

### Performance

fzf is fast. Performance should not be a problem in most use cases. However,
you might want to be aware of the options that can affect performance.

- `--ansi` tells fzf to extract and parse ANSI color codes in the input, and it
  makes the initial scanning slower. So it's not recommended that you add it
  to your `$FZF_DEFAULT_OPTS`.
- `--nth` makes fzf slower because it has to tokenize each line.
- A plain string `--delimiter` should be preferred over a regular expression
  delimiter.
- `--with-nth` makes fzf slower as fzf has to tokenize and reassemble each
  line.

### Executing external programs

You can set up key bindings for starting external processes without leaving
fzf (`execute`, `execute-silent`).

```bash
# Press F1 to open the file with less without leaving fzf
# Press CTRL-Y to copy the line to clipboard and aborts fzf (requires pbcopy)
fzf --bind 'f1:execute(less -f {}),ctrl-y:execute-silent(echo {} | pbcopy)+abort'
```

See *KEY/EVENT BINDINGS* section of the man page for details.

### Turning into a different process

`become(...)` is similar to `execute(...)`/`execute-silent(...)` described
above, but instead of executing the command and coming back to fzf on
complete, it turns fzf into a new process for the command.

```sh
fzf --bind 'enter:become(vim {})'
```

Compared to the seemingly equivalent command substitution `vim "$(fzf)"`, this
approach has several advantages:

* Vim will not open an empty file when you terminate fzf with
  <kbd>CTRL-C</kbd>
* Vim will not open an empty file when you press <kbd>ENTER</kbd> on an empty
  result
* Can handle multiple selections even when they have whitespaces
  ```sh
  fzf --multi --bind 'enter:become(vim {+})'
  ```

To be fair, running `fzf --print0 | xargs -0 -o vim` instead of `vim "$(fzf)"`
resolves all of the issues mentioned. Nonetheless, `become(...)` still offers
additional benefits in different scenarios.

* You can set up multiple bindings to handle the result in different ways
  without any wrapping script
  ```sh
  fzf --bind 'enter:become(vim {}),ctrl-e:become(emacs {})'
  ```
  * Previously, you would have to use `--expect=ctrl-e` and check the first
    line of the output of fzf
* You can easily build the subsequent command using the field index
  expressions of fzf
  ```sh
  # Open the file in Vim and go to the line
  git grep --line-number . |
      fzf --delimiter : --nth 3.. --bind 'enter:become(vim {1} +{2})'
  ```

### Reloading the candidate list

By binding `reload` action to a key or an event, you can make fzf dynamically
reload the candidate list. See https://github.com/junegunn/fzf/issues/1750 for
more details.

#### 1. Update the list of processes by pressing CTRL-R

```sh
ps -ef |
  fzf --bind 'ctrl-r:reload(ps -ef)' \
      --header 'Press CTRL-R to reload' --header-lines=1 \
      --height=50% --layout=reverse
```

#### 2. Switch between sources by pressing CTRL-D or CTRL-F

```sh
FZF_DEFAULT_COMMAND='find . -type f' \
  fzf --bind 'ctrl-d:reload(find . -type d),ctrl-f:reload(eval "$FZF_DEFAULT_COMMAND")' \
      --height=50% --layout=reverse
```

#### 3. Interactive ripgrep integration

The following example uses fzf as the selector interface for ripgrep. We bound
`reload` action to `change` event, so every time you type on fzf, the ripgrep
process will restart with the updated query string denoted by the placeholder
expression `{q}`. Also, note that we used `--disabled` option so that fzf
doesn't perform any secondary filtering.

```sh
: | rg_prefix='rg --column --line-number --no-heading --color=always --smart-case' \
    fzf --bind 'start:reload:$rg_prefix ""' \
        --bind 'change:reload:$rg_prefix {q} || true' \
        --bind 'enter:become(vim {1} +{2})' \
        --ansi --disabled \
        --height=50% --layout=reverse
```

If ripgrep doesn't find any matches, it will exit with a non-zero exit status,
and fzf will warn you about it. To suppress the warning message, we added
`|| true` to the command, so that it always exits with 0.

See ["Using fzf as interactive Ripgrep launcher"](https://github.com/junegunn/fzf/blob/master/ADVANCED.md#using-fzf-as-interactive-ripgrep-launcher)
for more sophisticated examples.

### Preview window

When the `--preview` option is set, fzf automatically starts an external process
with the current line as the argument and shows the result in the split window.
Your `$SHELL` is used to execute the command with `$SHELL -c COMMAND`.
The window can be scrolled using the mouse or custom key bindings.

```bash
# {} is replaced with the single-quoted string of the focused line
fzf --preview 'cat {}'
```

Preview window supports ANSI colors, so you can use any program that
syntax-highlights the content of a file, such as
[Bat](https://github.com/sharkdp/bat) or
[Highlight](https://gitlab.com/saalen/highlight):

```bash
fzf --preview 'bat --color=always {}' --preview-window '~3'
```

You can customize the size, position, and border of the preview window using
`--preview-window` option, and the foreground and background color of it with
`--color` option. For example,

```bash
fzf --height 40% --layout reverse --info inline --border \
    --preview 'file {}' --preview-window up,1,border-horizontal \
    --bind 'ctrl-/:change-preview-window(50%|hidden|)' \
    --color 'fg:#bbccdd,fg+:#ddeeff,bg:#334455,preview-bg:#223344,border:#778899'
```

See the man page (`man fzf`) for the full list of options.

More advanced examples can be found [here](https://github.com/junegunn/fzf/blob/master/ADVANCED.md).

> [!WARNING]
> Since fzf is a general-purpose text filter rather than a file finder, **it is
> not a good idea to add `--preview` option to your `$FZF_DEFAULT_OPTS`**.
>
> ```sh
> # *********************
> # ** DO NOT DO THIS! **
> # *********************
> export FZF_DEFAULT_OPTS='--preview "bat --style=numbers --color=always --line-range :500 {}"'
>
> # bat doesn't work with any input other than the list of files
> ps -ef | fzf
> seq 100 | fzf
> history | fzf
> ```

### Previewing an image

fzf can display images in the preview window using one of the following protocols:

* [Kitty graphics protocol](https://sw.kovidgoyal.net/kitty/graphics-protocol/)
* [iTerm2 inline images protocol](https://iterm2.com/documentation-images.html)
* [Sixel](https://en.wikipedia.org/wiki/Sixel)

See [bin/fzf-preview.sh](bin/fzf-preview.sh) script for more information.

```sh
fzf --preview 'fzf-preview.sh {}'
```

Tips
----

### Respecting `.gitignore`

You can use [fd](https://github.com/sharkdp/fd),
[ripgrep](https://github.com/BurntSushi/ripgrep), or [the silver
searcher](https://github.com/ggreer/the_silver_searcher) to traverse the file
system while respecting `.gitignore`.

```sh
# Feed the output of fd into fzf
fd --type f --strip-cwd-prefix | fzf

# Setting fd as the default source for fzf
export FZF_DEFAULT_COMMAND='fd --type f --strip-cwd-prefix'

# Now fzf (w/o pipe) will use the fd command to generate the list
fzf

# To apply the command to CTRL-T as well
export FZF_CTRL_T_COMMAND="$FZF_DEFAULT_COMMAND"
```

If you want the command to follow symbolic links and don't want it to exclude
hidden files, use the following command:

```sh
export FZF_DEFAULT_COMMAND='fd --type f --strip-cwd-prefix --hidden --follow --exclude .git'
```

### Fish shell

`CTRL-T` key binding of fish, unlike those of bash and zsh, will use the last
token on the command-line as the root directory for the recursive search. For
instance, hitting `CTRL-T` at the end of the following command-line

```sh
ls /var/
```

will list all files and directories under `/var/`.

When using a custom `FZF_CTRL_T_COMMAND`, use the unexpanded `$dir` variable to
make use of this feature. `$dir` defaults to `.` when the last token is not a
valid directory. Example:

```sh
set -g FZF_CTRL_T_COMMAND "command find -L \$dir -type f 2> /dev/null | sed '1d; s#^\./##'"
```

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*

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.

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)
  `preview-fg`  /  `preview-bg`  | Preview window text and background
  `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
  `query`                      | Query string
  `disabled`                   | Query string when search is disabled
  `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 to 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 traverse the file system
under the current directory to get the list of files. (If
`$FZF_DEFAULT_COMMAND` is set, fzf will use the output of the command
instead.) 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'})
<
You can use any shell command as the source to generate the list. 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       | Function to be called with each selected item
  `sinklist`  (or  `sink*` )    | funcref       | Similar to  `sink` , but takes the list of output lines at once
  `exit`                      | funcref       | Function to be called with the exit status of fzf (e.g. 0, 1, 2, 130)
  `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%` )
  `popup` / `tmux`              | string        | (Layout) `--popup` options (e.g.  `90%,70%` )
  `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]] or [integer range [8 ~ ]]
   - `height` [float range [0 ~ 1]] or [integer range [4 ~ ]]
 - Optional:
   - `yoffset` [float default 0.5 range [0 ~ 1]]
   - `xoffset` [float default 0.5 range [0 ~ 1]]
   - `relative` [boolean default v:false]
   - `border` [string default `rounded` (`sharp` on Windows)]: Border style
     - `rounded` / `sharp` / `horizontal` / `vertical` / `top` / `bottom` / `left` / `right` / `no[ne]`


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 (configurable via
`g:fzf_action`) 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))
<

                                      *fzf-global-options-supported-by-fzf#wrap*

 - `g:fzf_layout`
 - `g:fzf_action`
   - Works only when no custom `sink` (or `sinklist`) is provided
     - Having custom sink usually means that each entry is not an ordinary
       file path (e.g. name of color scheme), so we can't blindly apply the
       same strategy (i.e. `tabedit some-color-scheme` doesn't make sense)
 - `g:fzf_colors`
 - `g:fzf_history_dir`


TIPS                                                                  *fzf-tips*

When fzf is configured to start in a terminal buffer inside Vim or Neovim, you
may find the default ANSI colors to be different. In that case, configure the
colors using `g:terminal_ansi_colors` in regular Vim or `g:terminal_color_x`

< Starting fzf in a tmux/Zellij popup window >________________________________~
                                 *fzf-starting-fzf-in-a-tmuxzellij-popup-window*

fzf can also start in a popup of the multiplexer instead of a window inside
Vim, by putting a `--popup` option value in the `popup` key. `tmux` is
accepted as a synonym, just as `--tmux` is an alias of `--popup`.

The layout works on tmux 3.3 or above, or on Zellij 0.44 or above with fzf
0.71.0 or above. It is the default on tmux 3.7 or above with fzf 0.74.0 or
above, and on Zellij, where the pane is not modal: Vim keeps the window fzf
was started from visible, and you can switch to it while fzf is open. Below
those versions tmux gives a popup that cannot be left, so a window inside Vim
is the default there. On tmux, an explicit `--border` style also gives a modal
popup rather than a floating pane, because the native border of a tmux
floating pane cannot be removed. Drop `--border` to keep the floating pane and
its native border. Zellij keeps the floating pane either way, and hides its
native border when fzf draws one. Set `g:fzf_layout` yourself to choose either
one.

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. This applies to the layouts that open inside Vim, not to the tmux
or Zellij pane the default uses, which is not a buffer.

For example, if you open fzf on the bottom on the screen (e.g. `{'down':
'40%'}`), you might want to temporarily disable the statusline for a cleaner
look.
