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 $2}' | xargs kill -9
|
||||
```
|
||||
|
||||
[filter]: https://en.wikipedia.org/wiki/Filter_(software)
|
||||
|
||||
While the above example succinctly summarizes the fundamental concept of fzf,
|
||||
you can build much more sophisticated interactive workflows using fzf once you
|
||||
learn its wide variety of features.
|
||||
|
||||
- To see the full list of options and features, see `man fzf`
|
||||
- To see the latest additions, see [CHANGELOG.md](CHANGELOG.md)
|
||||
|
||||
This document will guide you through some examples that will familiarize you
|
||||
with the advanced features of fzf.
|
||||
|
||||
Screen Layout
|
||||
-------------
|
||||
|
||||
### `--height`
|
||||
|
||||
fzf by default opens in fullscreen mode, but it's not always desirable.
|
||||
Oftentimes, you want to see the current context of the terminal while using
|
||||
fzf. `--height` is an option for opening fzf below the cursor in
|
||||
non-fullscreen mode so you can still see the previous commands and their
|
||||
results above it.
|
||||
|
||||
```sh
|
||||
fzf --height=40%
|
||||
```
|
||||
|
||||
|
||||
|
||||
You might also want to experiment with other layout options such as
|
||||
`--layout=reverse`, `--info=inline`, `--border`, `--margin`, etc.
|
||||
|
||||
```sh
|
||||
fzf --height=40% --layout=reverse
|
||||
fzf --height=40% --layout=reverse --info=inline
|
||||
fzf --height=40% --layout=reverse --info=inline --border
|
||||
fzf --height=40% --layout=reverse --info=inline --border --margin=1
|
||||
fzf --height=40% --layout=reverse --info=inline --border --margin=1 --padding=1
|
||||
```
|
||||
|
||||
|
||||
|
||||
*(See `Layout` section of the man page to see the full list of options)*
|
||||
|
||||
But you definitely don't want to repeat `--height=40% --layout=reverse
|
||||
--info=inline --border --margin=1 --padding=1` every time you use fzf. You
|
||||
could write a wrapper script or shell alias, but there is an easier option.
|
||||
Define `$FZF_DEFAULT_OPTS` like so:
|
||||
|
||||
```sh
|
||||
export FZF_DEFAULT_OPTS="--height=40% --layout=reverse --info=inline --border --margin=1 --padding=1"
|
||||
```
|
||||
|
||||
### `fzf-tmux`
|
||||
|
||||
Before fzf had `--height` option, we would open fzf in a tmux split pane not
|
||||
to take up the whole screen. This is done using `fzf-tmux` script.
|
||||
|
||||
```sh
|
||||
# Open fzf on a tmux split pane below the current pane.
|
||||
# Takes the same set of options.
|
||||
fzf-tmux --layout=reverse
|
||||
```
|
||||
|
||||
|
||||
|
||||
The limitation of `fzf-tmux` is that it only works when you're on tmux unlike
|
||||
`--height` option. But the advantage of it is that it's more flexible.
|
||||
(See `man fzf-tmux` for available options.)
|
||||
|
||||
```sh
|
||||
# On the right (50%)
|
||||
fzf-tmux -r
|
||||
|
||||
# On the left (30%)
|
||||
fzf-tmux -l30%
|
||||
|
||||
# Above the cursor
|
||||
fzf-tmux -u30%
|
||||
```
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
#### Popup window support
|
||||
|
||||
But here's the really cool part; tmux 3.2 added support for popup windows. So
|
||||
you can open fzf in a popup window, which is quite useful if you frequently
|
||||
use split panes.
|
||||
|
||||
```sh
|
||||
# Open tmux in a tmux popup window (default size: 50% of the screen)
|
||||
fzf-tmux -p
|
||||
|
||||
# 80% width, 60% height
|
||||
fzf-tmux -p 80%,60%
|
||||
```
|
||||
|
||||
|
||||
|
||||
> You might also want to check out my tmux plugins which support this popup
|
||||
> window layout.

|
||||
|
||||
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
|
||||
```
|
||||
|
||||
|
||||
|
||||
- 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' \
|

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
|
||||
IFS=: read -ra selected < <(
|
||||
rg --color=always --line-number --no-heading --smart-case "${*:-}" |
|
||||
fzf --ansi \
|
||||
--color "hl:-1:underline,hl+:-1:underline:reverse" \
|
||||
--delimiter : \
|
||||
--preview 'bat --color=always {1} --highlight-line {2}' \
|
||||
--preview-window 'up,60%,border-bottom,+{2}+3/3,~3'
|
||||
)
|
||||
[ -n "${selected[0]}" ] && vim "${selected[0]}" "+${selected[1]}"
|
||||
```
|
||||
|
||||
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.
|
||||
|
||||
|
||||
|
||||
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
|
||||
- ```
|
||||
───────┬──────────────────────────────────────────────────────────

||||
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
|
||||
- Once we selected a line, we open the file with `vim` (`vim
|
||||
"${selected[0]}"`) and move the cursor to the line (`+${selected[1]}`).
|
||||
|
||||
### Using fzf as interative 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="${*:-}"
|
||||
IFS=: read -ra selected < <(
|
||||
FZF_DEFAULT_COMMAND="$RG_PREFIX $(printf %q "$INITIAL_QUERY")" \
|
||||
fzf --ansi \
|
||||
--disabled --query "$INITIAL_QUERY" \
|
||||
--bind "change:reload:sleep 0.1; $RG_PREFIX {q} || true" \
|
||||
--delimiter : \
|
||||
--preview 'bat --color=always {1} --highlight-line {2}' \
|
||||
--preview-window 'up,60%,border-bottom,+{2}+3/3,~3'
|
||||
)
|
||||
[ -n "${selected[0]}" ] && vim "${selected[0]}" "+${selected[1]}"
|
||||
```
|
||||
|
||||
|
||||
|
||||
- Instead of starting fzf in `rg ... | fzf` form, we start fzf without an
|
||||
explicit input, but with a custom `FZF_DEFAULT_COMMAND` variable. This way
|
||||
fzf can kill the initial Ripgrep process it starts with the initial query.
|
||||
Otherwise, the initial Ripgrep process will keep consuming system resources
|
||||
even after `reload` is triggered.
|
||||
- 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
|
||||
|
||||
*(Requires fzf 0.27.1 or above)*
|
||||
|
||||
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="${*:-}"
|
||||
IFS=: read -ra selected < <(
|
||||
FZF_DEFAULT_COMMAND="$RG_PREFIX $(printf %q "$INITIAL_QUERY")" \
|
||||
fzf --ansi \
|
||||
--color "hl:-1:underline,hl+:-1:underline:reverse" \
|
||||
--disabled --query "$INITIAL_QUERY" \
|
||||
--bind "change:reload:sleep 0.1; $RG_PREFIX {q} || true" \
|
||||
--bind "alt-enter:unbind(change,alt-enter)+change-prompt(2. fzf> )+enable-search+clear-query" \
|
||||
--prompt '1. ripgrep> ' \
|
||||
--delimiter : \
|
||||
--preview 'bat --color=always {1} --highlight-line {2}' \
|
||||
--preview-window 'up,60%,border-bottom,+{2}+3/3,~3'
|
||||
)
|
||||
[ -n "${selected[0]}" ] && vim "${selected[0]}" "+${selected[1]}"
|
||||
```
|
||||
|
||||
* Phase 1. Filtering with Ripgrep
|
||||
|
||||
* Phase 2. Filtering with fzf
|
||||
|
||||
|
||||
- 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
|
||||
|
||||
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'
|
||||
```
|
||||
|
||||
|
||||
|
||||
Admittedly, that was a silly example. Here's a practical one for browsing
|
||||
Kubernetes pods.
|
||||
|
||||
```bash
|
||||
#!/usr/bin/env bash
|
||||
|
||||
read -ra tokens < <(
|
||||
kubectl get pods --all-namespaces |
|
||||
fzf --info=inline --layout=reverse --header-lines=1 --border \
|
||||
--prompt "$(kubectl config current-context | sed 's/-context$//')> " \
|
||||
--header $'Press CTRL-O to open log in editor\n\n' \
|
||||
--bind ctrl-/:toggle-preview \
|
||||
--bind 'ctrl-o:execute:${EDITOR:-vim} <(kubectl logs --namespace {1} {2}) > /dev/tty' \
|
||||
--preview-window up,follow \
|
||||
--preview 'kubectl logs --follow --tail=100000 --namespace {1} {2}' "$@"
|
||||
)
|
||||
[ ${#tokens} -gt 1 ] &&
|
||||
kubectl exec -it --namespace "${tokens[0]}" "${tokens[1]}" -- bash
|
||||
```
|
||||
|
||||
|
||||
|
||||
- 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=100000`.
|
||||
- With `execute` binding, you can press CTRL-O to open the log in your editor
|
||||
without leaving fzf
|
||||
- Select a pod (with an enter key) to `kubectl exec` into it
|
||||
|
||||
Key bindings for git objects
|
||||

|
||||
|
||||
I have [blogged](https://junegunn.kr/2016/07/fzf-git) about my fzf+git key
|
||||
bindings a few years ago. I'm going to show them here again, 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'
|
||||
```
|
||||
|
||||
|
||||
|
||||
```sh
|
||||
# junegunn/seoul256.vim (light)
|
||||
export FZF_DEFAULT_OPTS='--color=bg+:#D9D9D9,bg:#E1E1E1,border:#C8C8C8,spinner:#719899,hl:#719872,fg:#616161,header:#719872,info:#727100,pointer:#E12672,marker:#E17899,fg+:#616161,preview-bg:#D9D9D9,prompt:#0099BD,hl+:#719899'
|
||||
```
|
||||
|
||||
|
||||
|
||||
```sh
|
||||
# morhetz/gruvbox
|
||||
export FZF_DEFAULT_OPTS='--color=bg+:#3c3836,bg:#32302f,spinner:#fb4934,hl:#928374,fg:#ebdbb2,header:#928374,info:#8ec07c,pointer:#fb4934,marker:#fb4934,fg+:#ebdbb2,prompt:#fb4934,hl+:#fb4934'
|
||||
```
|
||||
|
||||
|
||||
|
||||
```sh
|
||||
# arcticicestudio/nord-vim
|
||||
export FZF_DEFAULT_OPTS='--color=bg+:#3B4252,bg:#2E3440,spinner:#81A1C1,hl:#616E88,fg:#D8DEE9,header:#616E88,info:#81A1C1,pointer:#81A1C1,marker:#81A1C1,fg+:#D8DEE9,prompt:#81A1C1,hl+:#81A1C1'
|
||||
```
|
||||
|
||||
|
||||
|
||||
```sh
|
||||
# tomasr/molokai
|
||||
export FZF_DEFAULT_OPTS='--color=bg+:#293739,bg:#1B1D1E,border:#808080,spinner:#E6DB74,hl:#7E8E91,fg:#F8F8F2,header:#7E8E91,info:#A6E22E,pointer:#A6E22E,marker:#F92672,fg+:#F8F8F2,prompt:#F92672,hl+:#F92672'
|
||||
```
|
||||
|
||||
|
||||
|
||||
### 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 1.13 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`

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 git
|
||||
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 git
|
||||
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 }'))
|
||||
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'],

|

\ 'header': ['fg', 'Comment'] }
|
||||
|
||||
" Enable per-command history
|
||||

|
||||
" - 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 use find command (or
|
||||
`$FZF_DEFAULT_COMMAND` if defined) to list the files under the current
|
||||
directory. When you select one, it will open it with 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'})
|
||||
```
|
||||
|
||||
Instead of using the default find command, you can use any shell command as
|
||||
the source. 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) fzf-tmux options (e.g. `-p90%,60%`) |
|
||||
| `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`]: 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 fzf-tmux options in `tmux` key.
|
||||
|
||||
```vim
|
||||
" See `man fzf-tmux` for available options
|
||||
if exists('$TMUX')
|
||||
let g:fzf_layout = { 'tmux': '-p90%,60%' }
|
||||
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
|
||||
```

### Windows
|
||||
|
||||
Pre-built binaries for Windows can be downloaded [here][bin]. fzf is also
|
||||
available via [Chocolatey][choco] and [Scoop][scoop]:
|
||||
|
||||
| Package manager | Command |
|
||||
| --- | --- |
|
||||
| Chocolatey | `choco install fzf` |
|
||||
| Scoop | `scoop install fzf` |
|
||||
|
||||
[choco]: https://chocolatey.org/packages/fzf
|
||||
[scoop]: https://github.com/ScoopInstaller/Main/blob/master/bucket/fzf.json
|
||||
|
||||
Known issues and limitations on Windows can be found on [the wiki
|
||||
page][windows-wiki].
|
||||
|
||||
[windows-wiki]: https://github.com/junegunn/fzf/wiki/Windows
|
||||
|
||||
### As Vim plugin
|
||||
|
||||
If you use
|
||||
[vim-plug](https://github.com/junegunn/vim-plug), add this line to your Vim
|
||||
configuration file:
|
||||
|
||||
```vim
|
||||
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
|
||||
```
|
||||
|
||||
`fzf#install()` makes sure that you have the latest binary, but it's optional,
|
||||
so you can omit it if you use a plugin manager that doesn't support hooks.
|
||||
|
||||
For more installation options, see [README-VIM.md](README-VIM.md).
|
||||
|
||||
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 use find command to fetch the list of
|
||||
files excluding hidden ones. (You can override the default command with
|
||||
`FZF_DEFAULT_COMMAND`)
|
||||
|
||||
```sh
|
||||
vim $(fzf)
|
||||
```
|
||||
|
||||
#### 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
|
||||
|
||||
#### Layout
|
||||
|
||||
fzf by default starts in fullscreen mode, but you can make it start below the
|
||||
cursor with `--height` option.
|
||||
|
||||
```sh
|
||||
vim $(fzf --height 40%)
|
||||
```
|
||||
|
||||
Also, check out `--reverse` and `--layout` options if you prefer
|
||||
"top-down" layout instead of the default "bottom-up" layout.
|
||||
|
||||
```sh
|
||||
vim $(fzf --height 40% --reverse)
|
||||
```
|
||||
|
||||
You can add these options to `$FZF_DEFAULT_OPTS` so that they're applied by
|
||||
default. For example,
|
||||
|
||||
```sh
|
||||
export FZF_DEFAULT_OPTS='--height 40% --layout=reverse --border'
|
||||
```
|
||||
|
||||
#### 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` |
|
||||
| `^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'`
|
||||
- > :warning: This variable is not used by shell extensions due to the
|
||||
> slight difference in requirements.
|
||||
>
|
||||
> (e.g. `CTRL-T` runs `$FZF_CTRL_T_COMMAND` instead, `vim **<tab>` runs
|
||||
> `_fzf_compgen_path()`, and `cd **<tab>` runs `_fzf_compgen_dir()`)
|
||||
>
|
||||
> The available options are described later in this document.
|
||||
- `FZF_DEFAULT_OPTS`
|
||||
- Default options
|
||||
- e.g. `export FZF_DEFAULT_OPTS="--layout=reverse --inline-info"`
|
||||
|
||||
#### Options
|

|
||||
|
||||
`fzf-tmux` script
|
||||
-----------------
|
||||
|
||||
[fzf-tmux](bin/fzf-tmux) is a bash script that opens fzf in a tmux pane.
|
||||
|
||||
```sh
|
||||
# usage: fzf-tmux [LAYOUT OPTIONS] [--] [FZF OPTIONS]
|
||||
|
||||
# See available options
|
||||
fzf-tmux --help
|
||||
|
||||
# select git branches in horizontal split below (15 lines)
|
||||
git branch | fzf-tmux -d 15
|
||||
|
||||
# select multiple words in vertical split on the left (20% of screen width)
|
||||
cat /usr/share/dict/words | fzf-tmux -l 20% --multi --reverse
|
||||
```
|
||||
|
||||
It will still work even when you're not on tmux, silently ignoring `-[pudlr]`
|
||||
options, so you can invariably use `fzf-tmux` in your scripts.
|
||||
|
||||
Alternatively, you can use `--height HEIGHT[%]` option not to start fzf in
|
||||
fullscreen mode.
|
||||
|
||||
```sh
|
||||
fzf --height 40%
|
||||
```
|
||||
|
||||
Key bindings for command-line
|
||||
-----------------------------
|
||||
|
||||
The install script will setup the following key bindings for bash, zsh, and
|
||||
fish.
|
||||
|
||||
- `CTRL-T` - Paste the selected files and directories onto the command-line
|
||||
- Set `FZF_CTRL_T_COMMAND` to override the default command
|
||||
- Set `FZF_CTRL_T_OPTS` to pass additional options
|
||||
- `CTRL-R` - Paste the selected command from history onto the command-line
|
||||
- If you want to see the commands in chronological order, press `CTRL-R`
|
||||
again which toggles sorting by relevance
|
||||
- Set `FZF_CTRL_R_OPTS` to pass additional options
|
||||
- `ALT-C` - cd into the selected directory
|
||||
- Set `FZF_ALT_C_COMMAND` to override the default command
|
||||
- Set `FZF_ALT_C_OPTS` to pass additional options
|
||||
|
||||
If you're on a tmux session, you can start fzf in a tmux split-pane or in
|
||||
a tmux popup window by setting `FZF_TMUX_OPTS` (e.g. `-d 40%`).
|
||||
See `fzf-tmux --help` for available options.

||||
Fuzzy completion for bash and zsh
|
||||
---------------------------------
|
||||
|
||||
#### 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. In this case,
|
||||
there is no trigger sequence; just press the tab key after the kill command.
|
||||
|
||||
```sh
|
||||
# Can select multiple processes with <TAB> or <Shift-TAB> keys
|
||||
kill -9 <TAB>
|
||||
```
|
||||
|
||||
#### Host names
|
||||
|
||||
For ssh and telnet commands, fuzzy completion for hostnames is provided. The
|
||||
names are extracted from /etc/hosts and ~/.ssh/config.
|
||||
|
||||
```sh
|
||||
ssh **<TAB>
|
||||
telnet **<TAB>
|
||||
```
|
||||
|
||||
#### Environment variables / Aliases
|
||||
|
||||
```sh
|
||||
unset **<TAB>
|
||||
export **<TAB>
|
||||
unalias **<TAB>
|
||||
```
|
||||
|
||||
#### Settings
|
||||
|
||||
```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'
|
||||
|
||||
# Use fd (https://github.com/sharkdp/fd) instead of the default find
|
||||
# command 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"
|
||||
}
|
||||
|
||||
# (EXPERIMENTAL) 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 "$@" --preview 'dig {}' ;;
|
||||
*) fzf "$@" ;;
|
||||
esac
|
||||
}
|
||||
```
|
||||
|
||||
#### Supported commands
|
||||
|
||||
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
|
||||
```

||||

|
||||
Advanced topics
|
||||
---------------
|
||||
|
||||
### Performance
|
||||
|
||||
fzf is fast and is [getting even faster][perf]. Performance should not be
|
||||
a problem in most use cases. However, you might want to be aware of the
|
||||
options that 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 `$FZF_DEFAULT_OPTS`.
|
||||
- `--nth` makes fzf slower because it has to tokenize each line.
|
||||
- `--with-nth` makes fzf slower as fzf has to tokenize and reassemble each
|
||||
line.
|
||||
- If you absolutely need better performance, you can consider using
|
||||
`--algo=v1` (the default being `v2`) to make fzf use a faster greedy
|
||||
algorithm. However, this algorithm is not guaranteed to find the optimal
|
||||
ordering of the matches and is not recommended.
|
||||
|
||||
[perf]: https://junegunn.kr/images/fzf-0.17.0.png
|
||||
|
||||
### Executing external programs
|
||||
|
||||
You can set up key bindings for starting external processes without leaving
|
||||
fzf (`execute`, `execute-silent`).
|
||||
|
||||
```bash
|
||||
# Press F1 to open the file with less without leaving fzf
|
||||
# Press CTRL-Y to copy the line to clipboard and aborts fzf (requires pbcopy)
|
||||
fzf --bind 'f1:execute(less -f {}),ctrl-y:execute-silent(echo {} | pbcopy)+abort'
|
||||
```
|
||||
|
||||
See *KEY BINDINGS* section of the man page for details.
|
||||
|
||||
### Reloading the candidate list
|
||||
|
||||
By binding `reload` action to a key or an event, you can make fzf dynamically
|
||||
reload the candidate list. See https://github.com/junegunn/fzf/issues/1750 for
|
||||
more details.
|
||||
|
||||
#### 1. Update the list of processes by pressing CTRL-R
|
||||
|
||||
```sh
|
||||
FZF_DEFAULT_COMMAND='ps -ef' \
|
||||
fzf --bind 'ctrl-r:reload($FZF_DEFAULT_COMMAND)' \
|
||||
--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($FZF_DEFAULT_COMMAND)' \
|
||||
--height=50% --layout=reverse
|
||||
```
|
||||
|
||||
#### 3. Interactive ripgrep integration
|
||||
|
||||
The following example uses fzf as the selector interface for ripgrep. We bound
|
||||
`reload` action to `change` event, so every time you type on fzf, the ripgrep
|
||||
process will restart with the updated query string denoted by the placeholder
|
||||
expression `{q}`. Also, note that we used `--disabled` option so that fzf
|
||||
doesn't perform any secondary filtering.
|
||||
|
||||
```sh
|
||||
INITIAL_QUERY=""
|
||||
RG_PREFIX="rg --column --line-number --no-heading --color=always --smart-case "
|
||||
FZF_DEFAULT_COMMAND="$RG_PREFIX '$INITIAL_QUERY'" \
|
||||
fzf --bind "change:reload:$RG_PREFIX {q} || true" \
|
||||
--ansi --disabled --query "$INITIAL_QUERY" \
|
||||
--height=50% --layout=reverse
|
||||
```
|
||||
|
||||
If ripgrep doesn't find any matches, it will exit with a non-zero exit status,
|
||||
and fzf will warn you about it. To suppress the warning message, we added
|
||||
`|| true` to the command, so that it always exits with 0.
|
||||
|
||||
### Preview window
|
||||
|
||||
When the `--preview` option is set, fzf automatically starts an external process
|
||||
with the current line as the argument and shows the result in the split window.
|
||||
Your `$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](http://www.andre-simon.de/doku/highlight/en/highlight.php):
|
||||
|
||||
```bash
|
||||
fzf --preview 'bat --style=numbers --color=always --line-range :500 {}'
|
||||
```
|
||||
|
||||
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 \
|
||||
--color 'fg:#bbccdd,fg+:#ddeeff,bg:#334455,preview-bg:#223344,border:#778899'
|
||||
```
|
||||
|
||||
See the man page (`man fzf`) for the full list of options.
|
||||

||||

|

|
||||
----
|
||||
|
||||
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 `$FZF_DEFAULT_OPTS`**.
|
||||
|
||||
```sh
|
||||
# *********************
|
||||
# ** DO NOT DO THIS! **
|
||||
# *********************
|
||||
export FZF_DEFAULT_OPTS='--preview "bat --style=numbers --color=always --line-range :500 {}"'
|
||||
|
||||
# bat doesn't work with any input other than the list of files
|
||||
ps -ef | fzf
|
||||
seq 100 | fzf
|
||||
history | fzf
|
||||
```
|
||||
|
||||
Tips
|
||||
----
|
||||
|
||||
#### Respecting `.gitignore`
|
||||
|
||||
You can use [fd](https://github.com/sharkdp/fd),
|
||||
[ripgrep](https://github.com/BurntSushi/ripgrep), or [the silver
|
||||
searcher](https://github.com/ggreer/the_silver_searcher) instead of the
|
||||
default find command to traverse the file system while respecting
|
||||
`.gitignore`.
|
||||
|
||||
```sh
|
||||
# Feed the output of fd into fzf
|
||||
fd --type f | fzf
|
||||
|
||||
# Setting fd as the default source for fzf
|
||||
export FZF_DEFAULT_COMMAND='fd --type f'
|
||||
|
||||
# Now fzf (w/o pipe) will use fd instead of find
|
||||
fzf
|
||||
|
||||
# To apply the command to CTRL-T as well
|
||||
export FZF_CTRL_T_COMMAND="$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 --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#^\./##'"
|
||||
```

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 git
|
||||
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 git
|
||||
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() } }

|

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.

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 use find command (or
|
||||
`$FZF_DEFAULT_COMMAND` if defined) to list the files under the current
|
||||
directory. When you select one, it will open it with 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'})
|
||||
<
|
||||
Instead of using the default find command, you can use any shell command as
|
||||
the source. 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) fzf-tmux options (e.g. `-p90%,60%` )
|
||||
`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`]: 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 `sink*`) 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`

< fzf inside terminal buffer >________________________________________________~
|
||||
*fzf-inside-terminal-buffer*
|
||||
|
||||
The latest versions of Vim and Neovim include builtin terminal emulator
|
||||
(`:terminal`) and fzf will start in a terminal buffer in the following cases:
|
||||
|
||||
- On Neovim
|
||||
- On GVim
|
||||
- On Terminal Vim with a non-default layout
|
||||
- `call fzf#run({'left': '30%'})` or `let g:fzf_layout = {'left': '30%'}`
|
||||
|
||||
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.

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.

|
||||
|
||||
.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.

||||

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)
