Introduction
------------
fzf is an interactive [Unix filter][filter] program that is designed to be
used with other Unix tools. It reads a list of items from the standard input,
allows you to select a subset of the items, and prints the selected ones to
the standard output. You can think of it as an interactive version of *grep*,
and it's already useful even if you don't know any of its options.
```sh
# 1. ps: Feed the list of processes to fzf
# 2. fzf: Interactively select a process using fuzzy matching algorithm
# 3. awk: Take the PID from the selected line
# 3. kill: Kill the process with the PID
ps -ef | fzf | awk '{print $2}' | xargs kill -9
```
[filter]: https://en.wikipedia.org/wiki/Filter_(software)
While the above example succinctly summarizes the fundamental concept of fzf,
you can build much more sophisticated interactive workflows using fzf once you
learn its wide variety of features.
- To see the full list of options and features, see `man fzf`
- To see the latest additions, see [CHANGELOG.md](CHANGELOG.md)
This document will guide you through some examples that will familiarize you
with the advanced features of fzf.
Display modes
-------------
### `--height`
fzf by default opens in fullscreen mode, but it's not always desirable.
Oftentimes, you want to see the current context of the terminal while using
fzf. `--height` is an option for opening fzf below the cursor in
non-fullscreen mode so you can still see the previous commands and their
results above it.
```sh
fzf --height=40%
```
![image](https://user-images.githubusercontent.com/700826/113379893-c184c680-93b5-11eb-9676-c7c0a2f01748.png)
You might also want to experiment with other layout options such as
`--layout=reverse`, `--info=inline`, `--border`, `--margin`, etc.
```sh
fzf --height=40% --layout=reverse
fzf --height=40% --layout=reverse --info=inline
fzf --height=40% --layout=reverse --info=inline --border
fzf --height=40% --layout=reverse --info=inline --border --margin=1
fzf --height=40% --layout=reverse --info=inline --border --margin=1 --padding=1
```
![image](https://user-images.githubusercontent.com/700826/113379932-dfeac200-93b5-11eb-9e28-df1a2ee71f90.png)
*(See `Layout` section of the man page to see the full list of options)*
But you definitely don't want to repeat `--height=40% --layout=reverse
--info=inline --border --margin=1 --padding=1` every time you use fzf. You
could write a wrapper script or shell alias, but there is an easier option.
Define `$FZF_DEFAULT_OPTS` like so:
```sh
export FZF_DEFAULT_OPTS="--height=40% --layout=reverse --info=inline --border --margin=1 --padding=1"
```
### `--tmux`
(Requires tmux 3.3 or later)
If you're using tmux, you can open fzf in a tmux popup using `--tmux` option.
```sh
# Open fzf in a tmux popup at the center of the screen with 70% width and height
fzf --tmux 70%
```
![image](https://github.com/junegunn/fzf/assets/700826/9c365405-c700-49b2-8985-60d822ed4cff)
`--tmux` option is silently ignored if you're not on tmux. So if you're trying
to avoid opening fzf in fullscreen, try specifying both `--height` and `--tmux`.
```sh
# --tmux is specified later so it takes precedence over --height when on tmux.
# If you're not on tmux, --tmux is ignored and --height is used instead.
fzf --height 70% --tmux 70%
```
You can also specify the position, width, and height of the popup window in
the following format:
* `[center|top|bottom|left|right][,SIZE[%]][,SIZE[%]]`
```sh
# 100% width and 60% height
fzf --tmux 100%,60% --border horizontal
```
![image](https://github.com/junegunn/fzf/assets/700826/f80d3514-d69f-42f2-a8de-a392a562bfcf)
```sh
# On the right (50% width)
fzf --tmux right
```
![image](https://github.com/junegunn/fzf/assets/700826/4033ade4-7efa-421b-a3fb-a430d197098a)
```sh
# On the left (40% width and 70% height)
fzf --tmux left,40%,70%
```

Dynamic reloading of the list
-----------------------------
fzf can dynamically update the candidate list using an arbitrary program with
`reload` bindings (The design document for `reload` can be found
[here][reload]).
[reload]: https://github.com/junegunn/fzf/issues/1750
### Updating the list of processes by pressing CTRL-R
This example shows how you can set up a binding for dynamically updating the
list without restarting fzf.
```sh
(date; ps -ef) |
fzf --bind='ctrl-r:reload(date; ps -ef)' \
--header=$'Press CTRL-R to reload\n\n' --header-lines=2 \
--preview='echo {}' --preview-window=down,3,wrap \
--layout=reverse --height=80% | awk '{print $2}' | xargs kill -9
```
![image](https://user-images.githubusercontent.com/700826/113465047-200c7c00-946c-11eb-918c-268f37a900c8.png)
- The initial command is `(date; ps -ef)`. It prints the current date and
time, and the list of the processes.
- With `--header` option, you can show any message as the fixed header.
- To disallow selecting the first two lines (`date` and `ps` header), we use
`--header-lines=2` option.
- `--bind='ctrl-r:reload(date; ps -ef)'` binds CTRL-R to `reload` action that
runs `date; ps -ef`, so we can update the list of the processes by pressing
CTRL-R.
- We use simple `echo {}` preview option, so we can see the entire line on the
preview window below even if it's too long
### Toggling between data sources
You're not limited to just one reload binding. Set up multiple bindings so
you can switch between data sources.
```sh
find * | fzf --prompt 'All> ' \
--header 'CTRL-D: Directories / CTRL-F: Files' \
--bind 'ctrl-d:change-prompt(Directories> )+reload(find * -type d)' \
--bind 'ctrl-f:change-prompt(Files> )+reload(find * -type f)'
```
![image](https://user-images.githubusercontent.com/700826/113465073-4af6d000-946c-11eb-858f-2372c0955f67.png)
![image](https://user-images.githubusercontent.com/700826/113465072-46321c00-946c-11eb-9b6f-cda3951df579.png)
### Toggling with a single key binding
The above example uses two different key bindings to toggle between two modes,
but can we just use a single key binding?
To make a key binding behave differently each time it is pressed, we need:
1. a way to store the current state. i.e. "which mode are we in?"
2. and a way to dynamically perform different actions depending on the state.
The following example shows how to 1. store the current mode in the prompt
string, 2. and use this information (`$FZF_PROMPT`) to determine which
actions to perform using the `transform` action.
```sh
fd --type file |
fzf --prompt 'Files> ' \
--header 'CTRL-T: Switch between Files/Directories' \
--bind 'ctrl-t:transform:[[ ! $FZF_PROMPT =~ Files ]] &&
echo "change-prompt(Files> )+reload(fd --type file)" ||
echo "change-prompt(Directories> )+reload(fd --type directory)"' \
--preview '[[ $FZF_PROMPT =~ Files ]] && bat --color=always {} || tree -C {}'
```
Ripgrep integration
-------------------
### Using fzf as the secondary filter
* Requires [bat][bat]
* Requires [Ripgrep][rg]
[bat]: https://github.com/sharkdp/bat
[rg]: https://github.com/BurntSushi/ripgrep
fzf is pretty fast for filtering a list that you will rarely have to think
about its performance. But it is not the right tool for searching for text
inside many large files, and in that case you should definitely use something
like [Ripgrep][rg].
In the next example, Ripgrep is the primary filter that searches for the given
text in files, and fzf is used as the secondary fuzzy filter that adds
interactivity to the workflow. And we use [bat][bat] to show the matching line in
the preview window.
This is a bash script and it will not run as expected on other non-compliant
shells. To avoid the compatibility issue, let's save this snippet as a script
file called `rfv`.
```bash
#!/usr/bin/env bash
# 1. Search for text in files using Ripgrep
# 2. Interactively narrow down the list using fzf
# 3. Open the file in Vim
rg --color=always --line-number --no-heading --smart-case "${*:-}" |
fzf --ansi \
--color "hl:-1:underline,hl+:-1:underline:reverse" \
--delimiter : \
--preview 'bat --color=always {1} --highlight-line {2}' \
--preview-window 'up,60%,border-bottom,+{2}+3/3,~3' \
--bind 'enter:become(vim {1} +{2})'
```
And run it with an initial query string.
```sh
# Make the script executable
chmod +x rfv
# Run it with the initial query "algo"
./rfv algo
```
> Ripgrep will perform the initial search and list all the lines that contain
`algo`. Then we further narrow down the list on fzf.
![image](https://user-images.githubusercontent.com/700826/113683873-a42a6200-96ff-11eb-9666-26ce4091b0e4.png)
I know it's a lot to digest, let's try to break down the code.
- Ripgrep prints the matching lines in the following format
```
man/man1/fzf.1:54:.BI "--algo=" TYPE
man/man1/fzf.1:55:Fuzzy matching algorithm (default: v2)
man/man1/fzf.1:58:.BR v2 " Optimal scoring algorithm (quality)"
src/pattern_test.go:7: "github.com/junegunn/fzf/src/algo"
```
The first token delimited by `:` is the file path, and the second token is
the line number of the matching line. They respectively correspond to `{1}`
and `{2}` in the preview command.
- `--preview 'bat --color=always {1} --highlight-line {2}'`
- As we run `rg` with `--color=always` option, we should tell fzf to parse
ANSI color codes in the input by setting `--ansi`.
- We customize how fzf colors various text elements using `--color` option.
`-1` tells fzf to keep the original color from the input. See `man fzf` for
available color options.
- The value of `--preview-window` option consists of 5 components delimited
by `,`
1. `up` — Position of the preview window
1. `60%` — Size of the preview window
1. `border-bottom` — Preview window border only on the bottom side
1. `+{2}+3/3` — Scroll offset of the preview contents
1. `~3` — Fixed header
- Let's break down the latter two. We want to display the bat output in the
preview window with a certain scroll offset so that the matching line is
positioned near the center of the preview window.
- `+{2}` — The base offset is extracted from the second token
- `+3` — We add 3 lines to the base offset to compensate for the header
part of `bat` output
- ```

│ File: CHANGELOG.md
───────┼──────────────────────────────────────────────────────────
1 │ CHANGELOG
2 │ =========
3 │
4 │ 0.26.0
5 │ ------
```
- `/3` adjusts the offset so that the matching line is shown at a third
position in the window
- `~3` makes the top three lines fixed header so that they are always
visible regardless of the scroll offset
- Instead of using shell script to process the final output of fzf, we use
`become(...)` action which was added in [fzf 0.38.0][0.38.0] to turn fzf
into a new process that opens the file with `vim` (`vim {1}`) and move the
cursor to the line (`+{2}`).
[0.38.0]: https://github.com/junegunn/fzf/blob/master/CHANGELOG.md#0380
### Using fzf as interactive Ripgrep launcher
We have learned that we can bind `reload` action to a key (e.g.
`--bind=ctrl-r:execute(ps -ef)`). In the next example, we are going to **bind
`reload` action to `change` event** so that whenever the user *changes* the
query string on fzf, `reload` action is triggered.
Here is a variation of the above `rfv` script. fzf will restart Ripgrep every
time the user updates the query string on fzf. Searching and filtering is
completely done by Ripgrep, and fzf merely provides the interactive interface.
So we lose the "fuzziness", but the performance will be better on larger
projects, and it will free up memory as you narrow down the results.
```bash
#!/usr/bin/env bash
# 1. Search for text in files using Ripgrep
# 2. Interactively restart Ripgrep with reload action
# 3. Open the file in Vim
RG_PREFIX="rg --column --line-number --no-heading --color=always --smart-case "
INITIAL_QUERY="${*:-}"
fzf --ansi --disabled --query "$INITIAL_QUERY" \
--bind "start:reload:$RG_PREFIX {q}" \
--bind "change:reload:sleep 0.1; $RG_PREFIX {q} || true" \
--delimiter : \
--preview 'bat --color=always {1} --highlight-line {2}' \
--preview-window 'up,60%,border-bottom,+{2}+3/3,~3' \
--bind 'enter:become(vim {1} +{2})'

- Instead of starting fzf in the usual `rg ... | fzf` form, we make it start
the initial Ripgrep process immediately via `start:reload` binding for the
consistency of the code.
- Filtering is no longer a responsibility of fzf; hence `--disabled`
- `{q}` in the reload command evaluates to the query string on fzf prompt.
- `sleep 0.1` in the reload command is for "debouncing". This small delay will
reduce the number of intermediate Ripgrep processes while we're typing in
a query.
### Switching to fzf-only search mode
In the previous example, we lost fuzzy matching capability as we completely
delegated search functionality to Ripgrep. But we can dynamically switch to
fzf-only search mode by *"unbinding"* `reload` action from `change` event.
```sh
#!/usr/bin/env bash
# Two-phase filtering with Ripgrep and fzf
#
# 1. Search for text in files using Ripgrep
# 2. Interactively restart Ripgrep with reload action
# * Press alt-enter to switch to fzf-only filtering
# 3. Open the file in Vim
RG_PREFIX="rg --column --line-number --no-heading --color=always --smart-case "
INITIAL_QUERY="${*:-}"
fzf --ansi --disabled --query "$INITIAL_QUERY" \
--bind "start:reload:$RG_PREFIX {q}" \
--bind "change:reload:sleep 0.1; $RG_PREFIX {q} || true" \
--bind "alt-enter:unbind(change,alt-enter)+change-prompt(2. fzf> )+enable-search+clear-query" \
--color "hl:-1:underline,hl+:-1:underline:reverse" \
--prompt '1. ripgrep> ' \
--delimiter : \
--preview 'bat --color=always {1} --highlight-line {2}' \
--preview-window 'up,60%,border-bottom,+{2}+3/3,~3' \
--bind 'enter:become(vim {1} +{2})'
```
* Phase 1. Filtering with Ripgrep
![image](https://user-images.githubusercontent.com/700826/119213880-735e8a80-bafd-11eb-8493-123e4be24fbc.png)
* Phase 2. Filtering with fzf
![image](https://user-images.githubusercontent.com/700826/119213887-7e191f80-bafd-11eb-98c9-71a1af9d7aab.png)
- We added `--prompt` option to show that fzf is initially running in "Ripgrep
launcher mode".
- We added `alt-enter` binding that
1. unbinds `change` event, so Ripgrep is no longer restarted on key press
2. changes the prompt to `2. fzf>`
3. enables search functionality of fzf
4. clears the current query string that was used to start Ripgrep process
5. and unbinds `alt-enter` itself as this is a one-off event
- We reverted `--color` option for customizing how the matching chunks are
displayed in the second phase
### Switching between Ripgrep mode and fzf mode
[fzf 0.30.0][0.30.0] added `rebind` action so we can "rebind" the bindings
that were previously "unbound" via `unbind`.
This is an improved version of the previous example that allows us to switch
between Ripgrep launcher mode and fzf-only filtering mode via CTRL-R and
CTRL-F.
```sh
#!/usr/bin/env bash
# Switch between Ripgrep launcher mode (CTRL-R) and fzf filtering mode (CTRL-F)
rm -f /tmp/rg-fzf-{r,f}
RG_PREFIX="rg --column --line-number --no-heading --color=always --smart-case "
INITIAL_QUERY="${*:-}"
fzf --ansi --disabled --query "$INITIAL_QUERY" \
--bind "start:reload($RG_PREFIX {q})+unbind(ctrl-r)" \
--bind "change:reload:sleep 0.1; $RG_PREFIX {q} || true" \
--bind "ctrl-f:unbind(change,ctrl-f)+change-prompt(2. fzf> )+enable-search+rebind(ctrl-r)+transform-query(echo {q} > /tmp/rg-fzf-r; cat /tmp/rg-fzf-f)" \
--bind "ctrl-r:unbind(ctrl-r)+change-prompt(1. ripgrep> )+disable-search+reload($RG_PREFIX {q} || true)+rebind(change,ctrl-f)+transform-query(echo {q} > /tmp/rg-fzf-f; cat /tmp/rg-fzf-r)" \
--color "hl:-1:underline,hl+:-1:underline:reverse" \
--prompt '1. ripgrep> ' \
--delimiter : \
--header ' CTRL-R (ripgrep mode) CTRL-F (fzf mode) ' \
--preview 'bat --color=always {1} --highlight-line {2}' \
--preview-window 'up,60%,border-bottom,+{2}+3/3,~3' \
--bind 'enter:become(vim {1} +{2})'
```
- To restore the query string when switching between modes, we store the
current query in `/tmp/rg-fzf-{r,f}` files and restore the query using
`transform-query` action which was added in [fzf 0.36.0][0.36.0].
- Also note that we unbind `ctrl-r` binding on `start` event which is
triggered once when fzf starts.
[0.30.0]: https://github.com/junegunn/fzf/blob/master/CHANGELOG.md#0300
[0.36.0]: https://github.com/junegunn/fzf/blob/master/CHANGELOG.md#0360
### Switching between Ripgrep mode and fzf mode using a single key binding
In contrast to the previous version, we use just one hotkey to toggle between
ripgrep and fzf mode. This is achieved by using the `$FZF_PROMPT` as a state
within the `transform` action, a feature introduced in [fzf 0.45.0][0.45.0]. A
more detailed explanation of this feature can be found in a previous section -
[Toggling with a single keybinding](#toggling-with-a-single-key-binding).
[0.45.0]: https://github.com/junegunn/fzf/blob/master/CHANGELOG.md#0450
When using the `transform` action, the placeholder (`\{q}`) should be escaped to
prevent immediate evaluation.
```sh
#!/usr/bin/env bash
# Switch between Ripgrep mode and fzf filtering mode (CTRL-T)
rm -f /tmp/rg-fzf-{r,f}
RG_PREFIX="rg --column --line-number --no-heading --color=always --smart-case "
INITIAL_QUERY="${*:-}"
fzf --ansi --disabled --query "$INITIAL_QUERY" \
--bind "start:reload:$RG_PREFIX {q}" \
--bind "change:reload:sleep 0.1; $RG_PREFIX {q} || true" \
--bind 'ctrl-t:transform:[[ ! $FZF_PROMPT =~ ripgrep ]] &&
echo "rebind(change)+change-prompt(1. ripgrep> )+disable-search+transform-query:echo \{q} > /tmp/rg-fzf-f; cat /tmp/rg-fzf-r" ||
echo "unbind(change)+change-prompt(2. fzf> )+enable-search+transform-query:echo \{q} > /tmp/rg-fzf-r; cat /tmp/rg-fzf-f"' \
--color "hl:-1:underline,hl+:-1:underline:reverse" \
--prompt '1. ripgrep> ' \
--delimiter : \
--header 'CTRL-T: Switch between ripgrep/fzf' \
--preview 'bat --color=always {1} --highlight-line {2}' \
--preview-window 'up,60%,border-bottom,+{2}+3/3,~3' \
--bind 'enter:become(vim {1} +{2})'
```
Log tailing
-----------
fzf can run long-running preview commands and render partial results before
completion. And when you specify `follow` flag in `--preview-window` option,
fzf will "`tail -f`" the result, automatically scrolling to the bottom.
```bash
# With "follow", preview window will automatically scroll to the bottom.
# "\033[2J" is an ANSI escape sequence for clearing the screen.
# When fzf reads this code it clears the previous preview contents.
fzf --preview-window follow --preview 'for i in $(seq 100000); do
echo "$i"
sleep 0.01
(( i % 300 == 0 )) && printf "\033[2J"
done'
```
![image](https://user-images.githubusercontent.com/700826/113473303-dd669600-94a3-11eb-88a9-1f61b996bb0e.png)
Admittedly, that was a silly example. Here's a practical one for browsing
Kubernetes pods.
```bash
pods() {
command='kubectl get pods --all-namespaces' fzf \
--info=inline --layout=reverse --header-lines=1 \
--prompt "$(kubectl config current-context | sed 's/-context$//')> " \
--header $' Enter (kubectl exec) CTRL-O (open log in editor) CTRL-R (reload) \n\n' \
--bind 'start:reload:$command' \
--bind 'ctrl-r:reload:$command' \
--bind 'ctrl-/:change-preview-window(80%,border-bottom|hidden|)' \
--bind 'enter:execute:kubectl exec -it --namespace {1} {2} -- bash' \
--bind 'ctrl-o:execute:${EDITOR:-vim} <(kubectl logs --all-containers --namespace {1} {2})' \
--preview-window up:follow \
--preview 'kubectl logs --follow --all-containers --tail=10000 --namespace {1} {2}' "$@"
}
```
![image](https://user-images.githubusercontent.com/700826/113473547-1d7a4880-94a5-11eb-98ef-9aa6f0ed215a.png)
- The preview window will *"log tail"* the pod
- Holding on to a large amount of log will consume a lot of memory. So we
limited the initial log amount with `--tail=10000`.
- `execute` bindings allow you to run any command without leaving fzf
- Press enter key on a pod to `kubectl exec` into it
- Press CTRL-O to open the log in your editor
- Press CTRL-R to reload the pod list
- Press CTRL-/ repeatedly to rotate through a different sets of preview
window options
1. `80%,border-bottom`
1. `hidden`
1. Empty string after `|` translates to the default options from `--preview-window`
Key bindings for git objects
----------------------------
Oftentimes, you want to put the identifiers of various Git object to the
command-line. For example, it is common to write commands like these:
```sh
git checkout [SOME_COMMIT_HASH or BRANCH or TAG]
git diff [SOME_COMMIT_HASH or BRANCH or TAG] [SOME_COMMIT_HASH or BRANCH or TAG]
```
[fzf-git.sh](https://github.com/junegunn/fzf-git.sh) project defines a set of
fzf-based key bindings for Git objects. I strongly recommend that you check
them out because they are seriously useful.

Color themes
------------
You can customize how fzf colors the text elements with `--color` option. Here
are a few color themes. Note that you need a terminal emulator that can
display 24-bit colors.
```sh
# junegunn/seoul256.vim (dark)
export FZF_DEFAULT_OPTS='--color=bg+:#3F3F3F,bg:#4B4B4B,border:#6B6B6B,spinner:#98BC99,hl:#719872,fg:#D9D9D9,header:#719872,info:#BDBB72,pointer:#E12672,marker:#E17899,fg+:#D9D9D9,preview-bg:#3F3F3F,prompt:#98BEDE,hl+:#98BC99'
```

### fzf Theme Playground
[fzf Theme Playground](https://vitormv.github.io/fzf-themes/) created by
[Vitor Mello](https://github.com/vitormv) is a webpage where you can
interactively create fzf themes.
### Generating fzf color theme from Vim color schemes
The Vim plugin of fzf can generate `--color` option from the current color
scheme according to `g:fzf_colors` variable. You can find the detailed
explanation [here](https://github.com/junegunn/fzf/blob/master/README-VIM.md#explanation-of-gfzf_colors).
Here is an example. Add this to your Vim configuration file.
```vim
let g:fzf_colors =
\ { 'fg': ['fg', 'Normal'],
\ 'bg': ['bg', 'Normal'],
\ 'preview-bg': ['bg', 'NormalFloat'],
\ 'hl': ['fg', 'Comment'],
\ 'fg+': ['fg', 'CursorLine', 'CursorColumn', 'Normal'],
\ 'bg+': ['bg', 'CursorLine', 'CursorColumn'],
\ 'hl+': ['fg', 'Statement'],
\ 'info': ['fg', 'PreProc'],
\ 'border': ['fg', 'Ignore'],
\ 'prompt': ['fg', 'Conditional'],
\ 'pointer': ['fg', 'Exception'],
\ 'marker': ['fg', 'Keyword'],
\ 'spinner': ['fg', 'Label'],
\ 'header': ['fg', 'Comment'] }
```
Then you can see how the `--color` option is generated by printing the result
of `fzf#wrap()`.
```vim
:echo fzf#wrap()
```
Use this command to append `export FZF_DEFAULT_OPTS="..."` line to the end of
the current file.
```vim
:call append('$', printf('export FZF_DEFAULT_OPTS="%s"', matchstr(fzf#wrap().options, "--color[^']*")))
```

Building fzf
============
Build instructions
------------------
### Prerequisites
- Go 1.20 or above
### Using Makefile
```sh
# Build fzf binary for your platform in target
make
# Build fzf binary and copy it to bin directory
make install
# Build fzf binaries and archives for all platforms using goreleaser
make build
# Publish GitHub release
make release
```
> [!WARNING]
> Makefile uses git commands to determine the version and the revision
> information for `fzf --version`. So if you're building fzf from an
> environment where its git information is not available, you have to manually
> set `$FZF_VERSION` and `$FZF_REVISION`.
>
> e.g. `FZF_VERSION=0.24.0 FZF_REVISION=tarball make`
> [!TIP]
> To build fzf with profiling options enabled, set `TAGS=pprof`
>
> ```sh
> TAGS=pprof make clean install
> fzf --profile-cpu /tmp/cpu.pprof --profile-mem /tmp/mem.pprof \
> --profile-block /tmp/block.pprof --profile-mutex /tmp/mutex.pprof
> ```

FZF Vim integration
===================
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.
```vim
" If installed using Homebrew
set rtp+=/usr/local/opt/fzf
" If installed using Homebrew on Apple Silicon
set rtp+=/opt/homebrew/opt/fzf
" If you have cloned fzf on ~/.fzf directory
set rtp+=~/.fzf
```
If you use [vim-plug](https://github.com/junegunn/vim-plug), the same can be
written as:
```vim
" If installed using Homebrew
Plug '/usr/local/opt/fzf'
" If installed using Homebrew on Apple Silicon
Plug '/opt/homebrew/opt/fzf'
" If you have cloned fzf on ~/.fzf directory
Plug '~/.fzf'
```
But if you want the latest Vim plugin file from GitHub rather than the one
included in the package, write:
```vim
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:
```vim
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
```
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](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[!]`
---------
```vim
" Look for files under current directory
:FZF
" Look for files under your home directory
:FZF ~
" With fzf command-line options
:FZF --reverse --info=inline /tmp
" Bang version starts fzf in fullscreen mode
:FZF!
```
Similarly to [ctrlp.vim](https://github.com/kien/ctrlp.vim), 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.
### Configuration
- `g:fzf_action`
- Customizable extra key bindings for opening selected files in different ways
- `g:fzf_layout`
- Determines the size and position of fzf window
- `g:fzf_colors`
- Customizes fzf colors to match the current color scheme
- `g:fzf_history_dir`
- Enables history feature
#### Examples
```vim
" This is the default extra key bindings
let g:fzf_action = {
\ 'ctrl-t': 'tab split',
\ 'ctrl-x': 'split',
\ 'ctrl-v': 'vsplit' }
" An action can be a reference to a function that processes selected lines
function! s:build_quickfix_list(lines)
call setqflist(map(copy(a:lines), '{ "filename": v:val, "lnum": 1 }'))
copen
cc
endfunction
let g:fzf_action = {
\ 'ctrl-q': function('s:build_quickfix_list'),
\ 'ctrl-t': 'tab split',
\ 'ctrl-x': 'split',
\ 'ctrl-v': 'vsplit' }
" Default fzf layout
" - Popup window (center of the screen)
let g:fzf_layout = { 'window': { 'width': 0.9, 'height': 0.6 } }
" - Popup window (center of the current window)
let g:fzf_layout = { 'window': { 'width': 0.9, 'height': 0.6, 'relative': v:true } }
" - Popup window (anchored to the bottom of the current window)
let g:fzf_layout = { 'window': { 'width': 0.9, 'height': 0.6, 'relative': v:true, 'yoffset': 1.0 } }
" - down / up / left / right
let g:fzf_layout = { 'down': '40%' }
" - Window using a Vim command
let g:fzf_layout = { 'window': 'enew' }
let g:fzf_layout = { 'window': '-tabnew' }
let g:fzf_layout = { 'window': '10new' }
" Customize fzf colors to match your color scheme
" - fzf#wrap translates this to a set of `--color` options
let g:fzf_colors =
\ { 'fg': ['fg', 'Normal'],
\ 'bg': ['bg', 'Normal'],
\ 'hl': ['fg', 'Comment'],
\ 'fg+': ['fg', 'CursorLine', 'CursorColumn', 'Normal'],
\ 'bg+': ['bg', 'CursorLine', 'CursorColumn'],
\ 'hl+': ['fg', 'Statement'],
\ 'info': ['fg', 'PreProc'],
\ 'border': ['fg', 'Ignore'],
\ 'prompt': ['fg', 'Conditional'],
\ 'pointer': ['fg', 'Exception'],
\ 'marker': ['fg', 'Keyword'],
\ 'spinner': ['fg', 'Label'],
\ 'header': ['fg', 'Comment'] }
" Enable per-command history
" - History files will be stored in the specified directory
" - When set, CTRL-N and CTRL-P will be bound to 'next-history' and
" 'previous-history' instead of 'down' and 'up'.
let g:fzf_history_dir = '~/.local/share/fzf-history'
```
##### Explanation of `g:fzf_colors`
`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 |
| `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 |
| `query` | Query string |
| `disabled` | Query string when search is disabled |
| `prompt` | Prompt before query (`> `) |
| `pointer` | Pointer to the current line (`>`) |
- `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:
```vim
'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:
```vim
:echo fzf#wrap()
```
`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.
```vim
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.
```vim
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.
```vim
call fzf#run({'source': 'git ls-files', 'sink': 'e'})
```
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
" 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.
```vim
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 |
| `sinklist` (or `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) `--tmux` 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.
```vim
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`
----------
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:
```vim
echo fzf#wrap({'source': 'ls'})
```
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 (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.
```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))
```
### 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 inside terminal buffer
On the latest versions of Vim and Neovim, fzf will start in a terminal buffer.
If you find the default ANSI colors to be different, consider configuring the
colors using `g:terminal_ansi_colors` in regular Vim or `g:terminal_color_x`
in Neovim.
```vim
" Terminal colors for seoul256 color scheme
if has('nvim')
let g:terminal_color_0 = '#4e4e4e'
let g:terminal_color_1 = '#d68787'
let g:terminal_color_2 = '#5f865f'
let g:terminal_color_3 = '#d8af5f'
let g:terminal_color_4 = '#85add4'
let g:terminal_color_5 = '#d7afaf'
let g:terminal_color_6 = '#87afaf'
let g:terminal_color_7 = '#d0d0d0'
let g:terminal_color_8 = '#626262'
let g:terminal_color_9 = '#d75f87'
let g:terminal_color_10 = '#87af87'
let g:terminal_color_11 = '#ffd787'
let g:terminal_color_12 = '#add4fb'
let g:terminal_color_13 = '#ffafaf'
let g:terminal_color_14 = '#87d7d7'
let g:terminal_color_15 = '#e4e4e4'
else
let g:terminal_ansi_colors = [
\ '#4e4e4e', '#d68787', '#5f865f', '#d8af5f',
\ '#85add4', '#d7afaf', '#87afaf', '#d0d0d0',
\ '#626262', '#d75f87', '#87af87', '#ffd787',
\ '#add4fb', '#ffafaf', '#87d7d7', '#e4e4e4'
\ ]
endif
```
### Starting fzf in a popup window
```vim
" Required:
" - width [float range [0 ~ 1]] or [integer range [8 ~ ]]
" - height [float range [0 ~ 1]] or [integer range [4 ~ ]]
"
" Optional:
" - xoffset [float default 0.5 range [0 ~ 1]]
" - yoffset [float default 0.5 range [0 ~ 1]]
" - relative [boolean default v:false]
" - 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 `--tmux` option value in `tmux` key.
```vim
" See `--tmux` option in `man fzf` for available options
" [center|top|bottom|left|right][,SIZE[%]][,SIZE[%]]
if exists('$TMUX')
let g:fzf_layout = { 'tmux': '90%,70%' }
else
let g:fzf_layout = { 'window': { 'width': 0.9, 'height': 0.6 } }
endif
```
### 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 open fzf on the bottom on the screen (e.g. `{'down':
'40%'}`), you might want to temporarily disable the statusline for a cleaner
look.
```vim
let g:fzf_layout = { 'down': '30%' }
autocmd! FileType fzf
autocmd FileType fzf set laststatus=0 noshowmode noruler
\| autocmd BufLeave <buffer> set laststatus=2 showmode ruler

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 Homebrew on Apple Silicon
set rtp+=/opt/homebrew/opt/fzf
" If you have cloned fzf on ~/.fzf directory
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 Homebrew on Apple Silicon
Plug '/opt/homebrew/opt/fzf'
" If you have cloned fzf on ~/.fzf directory
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() } }
<
{1} https://github.com/junegunn/vim-plug
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.

:FZF[!]
==============================================================================
*:FZF*

" Look for files under current directory
:FZF
" Look for files under your home directory
:FZF ~
" With fzf command-line options
:FZF --reverse --info=inline /tmp
" Bang version starts fzf in fullscreen mode
:FZF!
<
Similarly to {ctrlp.vim}{3}, 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)
`preview-fg` / `preview-bg` | Preview window text and background
`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
`query` | Query string
`disabled` | Query string when search is disabled
`prompt` | Prompt before query ( `> ` )
`pointer` | Pointer to the current line ( `>` )
----------------------------+------------------------------------------------------
- `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 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 | Reference to function to process each selected item
`sinklist` (or `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) `--tmux` 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))
<
< Global options supported by fzf#wrap >______________________________________~
*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*
==============================================================================
< fzf inside terminal buffer >________________________________________________~
*fzf-inside-terminal-buffer*
On the latest versions of Vim and Neovim, fzf will start in a terminal buffer.
If you find the default ANSI colors to be different, consider configuring the
colors using `g:terminal_ansi_colors` in regular Vim or `g:terminal_color_x`
in Neovim.

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

.TH fzf\-tmux 1 "Jun 2024" "fzf 0.53.0" "fzf\-tmux - open fzf in tmux split pane"
.SH NAME
fzf\-tmux - open fzf in tmux split pane
.SH SYNOPSIS
.B fzf\-tmux [LAYOUT OPTIONS] [\-\-] [FZF OPTIONS]
.SH DESCRIPTION
fzf\-tmux is a wrapper script for fzf that opens fzf in a tmux split pane or in
a tmux popup window. It is designed to work just like fzf except that it does
not take up the whole screen. You can safely use fzf\-tmux instead of fzf in
your scripts as the extra options will be silently ignored if you're not on
tmux.
.SH LAYOUT OPTIONS
(default layout: \fB\-d 50%\fR)
.SS Popup window
(requires tmux 3.2 or above)
.TP
.B "\-p [WIDTH[%][,HEIGHT[%]]]"
.TP
.B "\-w WIDTH[%]"
.TP
.B "\-h WIDTH[%]"
.TP
.B "\-x COL"
.TP
.B "\-y ROW"
.SS Split pane
.TP
.B "\-u [height[%]]"
Split above (up)
.TP
.B "\-d [height[%]]"
Split below (down)
.TP
.B "\-l [width[%]]"
Split left
.TP
.B "\-r [width[%]]"
Split right

Algorithm
---------
FuzzyMatchV1 finds the first "fuzzy" occurrence of the pattern within the given
text in O(n) time where n is the length of the text. Once the position of the
last character is located, it traverses backwards to see if there's a shorter
substring that matches the pattern.
a_____b___abc__ To find "abc"
*-----*-----*> 1. Forward scan
<*** 2. Backward scan
The algorithm is simple and fast, but as it only sees the first occurrence,
it is not guaranteed to find the occurrence with the highest score.
a_____b__c__abc
*-----*--* ***
FuzzyMatchV2 implements a modified version of Smith-Waterman algorithm to find
the optimal solution (highest score) according to the scoring criteria. Unlike
the original algorithm, omission or mismatch of a character in the pattern is
not allowed.
Performance
-----------
The new V2 algorithm is slower than V1 as it examines all occurrences of the
pattern instead of stopping immediately after finding the first one. The time
complexity of the algorithm is O(nm) if a match is found and O(n) otherwise
where n is the length of the item and m is the length of the pattern. Thus, the
performance overhead may not be noticeable for a query with high selectivity.
However, if the performance is more important than the quality of the result,
you can still choose v1 algorithm with --algo=v1.
Scoring criteria

- We prefer matches at special positions, such as the start of a word, or
uppercase character in camelCase words.
- That is, we prefer an occurrence of the pattern with more characters
matching at special positions, even if the total match length is longer.
e.g. "fuzzyfinder" vs. "fuzzy-finder" on "ff"
````````````
- Also, if the first character in the pattern appears at one of the special
positions, the bonus point for the position is multiplied by a constant
as it is extremely likely that the first character in the typed pattern
has more significance than the rest.
e.g. "fo-bar" vs. "foob-r" on "br"
``````
- But since fzf is still a fuzzy finder, not an acronym finder, we should also
consider the total length of the matched substring. This is why we have the
gap penalty. The gap penalty increases as the length of the gap (distance
between the matching characters) increases, so the effect of the bonus is
eventually cancelled at some point.
e.g. "fuzzyfinder" vs. "fuzzy-blurry-finder" on "ff"
```````````
- Consequently, it is crucial to find the right balance between the bonus
and the gap penalty. The parameters were chosen that the bonus is cancelled
when the gap size increases beyond 8 characters.
- The bonus mechanism can have the undesirable side effect where consecutive
matches are ranked lower than the ones with gaps.
e.g. "foobar" vs. "foo-bar" on "foob"
```````
- To correct this anomaly, we also give extra bonus point to each character
in a consecutive matching chunk.
e.g. "foobar" vs. "foo-bar" on "foob"
``````
- The amount of consecutive bonus is primarily determined by the bonus of the
first character in the chunk.
e.g. "foobar" vs. "out-of-bound" on "oob"
````````````

You can read each line in the following table as a pipeline that
consist of series of parsers that act upon your input (col. 1) and
each cell represents the output value.
For example:
- exec.Command("program.exe", `\''`)
- goes to win32 api which will process it transparently as it contains no special characters, see [CommandLineToArgvW][].
- powershell command will receive it as is, that is two arguments: a literal backslash and empty string in single quotes
- native command run via/from powershell will receive only one argument: a literal backslash. Because extra parsing rules apply, see [NativeCallsFromPowershell][].
- some¹ apps have internal parser, that requires one more level of escaping (yes, this is completely application-specific, but see terminal_test.go#TestWindowsCommands)
