CHANGELOG
=========
0.51.0
------
- Added a new environment variable `$FZF_POS` exported to the child processes. It's the vertical position of the cursor in the list starting from 1.
```sh
# Toggle selection to the top or to the bottom
seq 30 | fzf --multi --bind 'load:pos(10)' \
--bind 'shift-up:transform:for _ in $(seq $FZF_POS $FZF_MATCH_COUNT); do echo -n +toggle+up; done' \
--bind 'shift-down:transform:for _ in $(seq 1 $FZF_POS); do echo -n +toggle+down; done'
```
- Added `--with-shell` option to start child processes with a custom shell command and flags
```sh
gem list | fzf --with-shell 'ruby -e' \
--preview 'pp Gem::Specification.find_by_name({1})' \
--bind 'ctrl-o:execute-silent:
spec = Gem::Specification.find_by_name({1})
[spec.homepage, *spec.metadata.filter { _1.end_with?("uri") }.values].uniq.each do
system "open", _1
end
'
```
- Added `change-multi` action for dynamically changing `--multi` option
- `change-multi` - enable multi-select mode with no limit
- `change-multi(NUM)` - enable multi-select mode with a limit
- `change-multi(0)` - disable multi-select mode
- `become` action is now supported on Windows
- Unlike in *nix, this does not use `execve(2)`. Instead it spawns a new process and waits for it to finish, so the exact behavior may differ.
- Bug fixes and improvements
0.50.0
------
- Search performance optimization. You can observe 50%+ improvement in some scenarios.
```
$ rg --line-number --no-heading --smart-case . > $DATA
$ wc < $DATA
5520118 26862362 897487793
$ hyperfine -w 1 -L bin fzf-0.49.0,fzf-7ce6452,fzf-a5447b8,fzf '{bin} --filter "///" < $DATA | head -30'
Summary
fzf --filter "///" < $DATA | head -30 ran
1.16 ± 0.03 times faster than fzf-a5447b8 --filter "///" < $DATA | head -30
1.23 ± 0.03 times faster than fzf-7ce6452 --filter "///" < $DATA | head -30
1.52 ± 0.03 times faster than fzf-0.49.0 --filter "///" < $DATA | head -30
```
- Added `jump` and `jump-cancel` events that are triggered when leaving `jump` mode
```sh
# Default behavior
fzf --bind space:jump
# Same as jump-accept action
fzf --bind space:jump,jump:accept
# Accept on jump, abort on cancel
fzf --bind space:jump,jump:accept,jump-cancel:abort
# Change header on jump-cancel
fzf --bind 'space:change-header(Type jump label)+jump,jump-cancel:change-header:Jump cancelled'
```
- Added a new environment variable `$FZF_KEY` exported to the child processes. It's the name of the last key pressed.
```sh
fzf --bind 'space:jump,jump:accept,jump-cancel:transform:[[ $FZF_KEY =~ ctrl-c ]] && echo abort'
```
- fzf can be built with profiling options. See [BUILD.md](BUILD.md) for more information.
- Bug fixes
0.49.0
------
- Ingestion performance improved by around 40% (more or less depending on options)
- `--info=hidden` and `--info=inline-right` will no longer hide the horizontal separator by default. This gives you more flexibility in customizing the layout.
```sh
fzf --border --info=inline-right
fzf --border --info=inline-right --separator ═
fzf --border --info=inline-right --no-separator
fzf --border --info=hidden
fzf --border --info=hidden --separator ━
fzf --border --info=hidden --no-separator
```
- Added two environment variables exported to the child processes
- `FZF_PREVIEW_LABEL`
- `FZF_BORDER_LABEL`
```sh
# Use the current value of $FZF_PREVIEW_LABEL to determine which actions to perform
git ls-files |
fzf --header 'Press CTRL-P to change preview mode' \
--bind='ctrl-p:transform:[[ $FZF_PREVIEW_LABEL =~ cat ]] \
&& echo "change-preview(git log --color=always \{})+change-preview-label([[ log ]])" \
|| echo "change-preview(bat --color=always \{})+change-preview-label([[ cat ]])"'
```
- Renamed `track` action to `track-current` to highlight the difference between the global tracking state set by `--track` and a one-off tracking action
- `track` is still available as an alias
- Added `untrack-current` and `toggle-track-current` actions
- `*-current` actions are no-op when the global tracking state is set
- Bug fixes and minor improvements
0.48.1
------
- CTRL-T and ALT-C bindings can be disabled by setting `FZF_CTRL_T_COMMAND` and `FZF_ALT_C_COMMAND` to empty strings respectively when sourcing the script
```sh
# bash
FZF_CTRL_T_COMMAND= FZF_ALT_C_COMMAND= eval "$(fzf --bash)"
# zsh
FZF_CTRL_T_COMMAND= FZF_ALT_C_COMMAND= eval "$(fzf --zsh)"
# fish
fzf --fish | FZF_CTRL_T_COMMAND= FZF_ALT_C_COMMAND= source
```
- Setting the variables after sourcing the script will have no effect
- Bug fixes
0.48.0
------
- Shell integration scripts are now embedded in the fzf binary. This simplifies the distribution, and the users are less likely to have problems caused by using incompatible scripts and binaries.
- bash
```sh
# Set up fzf key bindings and fuzzy completion
eval "$(fzf --bash)"
```
- zsh
```sh
# Set up fzf key bindings and fuzzy completion
eval "$(fzf --zsh)"
```
- fish
```fish
# Set up fzf key bindings
fzf --fish | source
```
- Added options for customizing the behavior of the built-in walker
| Option | Description | Default |
| --- | --- | --- |
| `--walker=OPTS` | Walker options (`[file][,dir][,follow][,hidden]`) | `file,follow,hidden` |
| `--walker-root=DIR` | Root directory from which to start walker | `.` |
| `--walker-skip=DIRS` | Comma-separated list of directory names to skip | `.git,node_modules` |
- Examples
```sh
# Built-in walker is only used by standalone fzf when $FZF_DEFAULT_COMMAND is not set
unset FZF_DEFAULT_COMMAND
fzf # default: --walker=file,follow,hidden --walker-root=. --walker-skip=.git,node_modules
fzf --walker=file,dir,hidden,follow --walker-skip=.git,node_modules,target
# Walker options in $FZF_DEFAULT_OPTS
export FZF_DEFAULT_OPTS="--walker=file,dir,hidden,follow --walker-skip=.git,node_modules,target"
fzf
# Reading from STDIN; --walker is ignored
seq 100 | fzf --walker=dir
# Reading from $FZF_DEFAULT_COMMAND; --walker is ignored
export FZF_DEFAULT_COMMAND='seq 100'
fzf --walker=dir
```
- Shell integration scripts have been updated to use the built-in walker with these new options and they are now much faster out of the box.
0.47.0
------
- Replaced ["the default find command"][find] with a built-in directory walker to simplify the code and to achieve better performance and consistent behavior across platforms.
This doesn't affect you if you have `$FZF_DEFAULT_COMMAND` set.
- Breaking changes:
- Unlike [the previous "find" command][find], the new traversal code will list hidden files, but hidden directories will still be ignored
- No filtering of `devtmpfs` or `proc` types
- Traversal is parallelized, so the order of the entries will be different each time
- You may wonder why fzf implements directory walker anyway when it's a filter program following the [Unix philosophy][unix].
But fzf has had [the walker code for years][walker] to tackle the performance problem on Windows. And I decided to use the same approach on different platforms as well for the benefits listed above.
- Built-in walker is using the excellent [charlievieth/fastwalk][fastwalk] library, which easily outperforms its competitors and supports safely following symlinks.
- Added `$FZF_DEFAULT_OPTS_FILE` to allow managing default options in a file
- See [#3618](https://github.com/junegunn/fzf/pull/3618)
- Option precedence from lower to higher
1. Options read from `$FZF_DEFAULT_OPTS_FILE`
1. Options from `$FZF_DEFAULT_OPTS`
1. Options from command-line arguments
- Bug fixes and improvements

0.46.1
------
- Bug fixes and improvements
- Fixed Windows binaries
- Downgraded Go version to 1.20 to support older versions of Windows
- https://tip.golang.org/doc/go1.21#windows
- Updated [rivo/uniseg](https://github.com/rivo/uniseg) dependency to v0.4.6
0.46.0
------
- Added two new events
- `result` - triggered when the filtering for the current query is complete and the result list is ready
- `resize` - triggered when the terminal size is changed
- fzf now exports the following environment variables to the child processes
| Variable | Description |
| --- | --- |
| `FZF_LINES` | Number of lines fzf takes up excluding padding and margin |
| `FZF_COLUMNS` | Number of columns fzf takes up excluding padding and margin |
| `FZF_TOTAL_COUNT` | Total number of items |
| `FZF_MATCH_COUNT` | Number of matched items |
| `FZF_SELECT_COUNT` | Number of selected items |
| `FZF_QUERY` | Current query string |
| `FZF_PROMPT` | Prompt string |
| `FZF_ACTION` | The name of the last action performed |
- This allows you to write sophisticated transformations like so
```sh
# Script to dynamically resize the preview window
transformer='
# 1 line for info, another for prompt, and 2 more lines for preview window border
lines=$(( FZF_LINES - FZF_MATCH_COUNT - 4 ))
if [[ $FZF_MATCH_COUNT -eq 0 ]]; then
echo "change-preview-window:hidden"
elif [[ $lines -gt 3 ]]; then
echo "change-preview-window:$lines"
elif [[ $FZF_PREVIEW_LINES -ne 3 ]]; then
echo "change-preview-window:3"
fi
'
seq 10000 | fzf --preview 'seq {} 10000' --preview-window up \
--bind "result:transform:$transformer" \
--bind "resize:transform:$transformer"
```
- And we're phasing out `{fzf:prompt}` and `{fzf:action}`
- Changed [mattn/go-runewidth](https://github.com/mattn/go-runewidth) dependency to [rivo/uniseg](https://github.com/rivo/uniseg) for accurate results
- Set `--ambidouble` if your terminal displays ambiguous width characters (e.g. box-drawing characters for borders) as 2 columns
- `RUNEWIDTH_EASTASIAN=1` is still respected for backward compatibility, but it's recommended that you use this new option instead
- Bug fixes
0.45.0
------
- Added `transform` action to conditionally perform a series of actions
```sh
# Disallow selecting an empty line
echo -e "1. Hello\n2. Goodbye\n\n3. Exit" |
fzf --height '~100%' --reverse --header 'Select one' \
--bind 'enter:transform:[[ -n {} ]] && echo accept || echo "change-header:Invalid selection"'
# Move cursor past the empty line
echo -e "1. Hello\n2. Goodbye\n\n3. Exit" |
fzf --height '~100%' --reverse --header 'Select one' \
--bind 'enter:transform:[[ -n {} ]] && echo accept || echo "change-header:Invalid selection"' \
--bind 'focus:transform:[[ -n {} ]] && exit; [[ {fzf:action} =~ up$ ]] && echo up || echo down'
# A single key binding to toggle between modes
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)"'
```
- Added placeholder expressions
- `{fzf:action}` - The name of the last action performed
- `{fzf:prompt}` - Prompt string (including ANSI color codes)
- `{fzf:query}` - Synonym for `{q}`
- Added support for negative height
```sh
# Terminal height minus 1, so you can still see the command line
fzf --height=-1
```
- This handles a terminal resize better than `--height=$(($(tput lines) - 1))`
- Added `accept-or-print-query` action that acts like `accept` but prints the
current query when there's no match for the query
```sh
# You can make CTRL-R paste the current query when there's no match
export FZF_CTRL_R_OPTS='--bind enter:accept-or-print-query'
```
- Note that there are alternative ways to implement the same strategy
```sh
# 'become' is apparently more versatile but it's not available on Windows.
export FZF_CTRL_R_OPTS='--bind "enter:become:if [ -z {} ]; then echo {q}; else echo {}; fi"'
# Using the new 'transform' action
export FZF_CTRL_R_OPTS='--bind "enter:transform:[ -z {} ] && echo print-query || echo accept"'
```
- Added `show-header` and `hide-header` actions
- Bug fixes
0.44.1
------
- Fixed crash when preview window is hidden on `focus` event
0.44.0
------
- (Experimental) Sixel image support in preview window (not available on Windows)
- [bin/fzf-preview.sh](bin/fzf-preview.sh) is added to demonstrate how to
display an image using Kitty image protocol or Sixel. You can use it
like so:
```sh
fzf --preview='fzf-preview.sh {}'
```
- (Experimental) iTerm2 inline image protocol support in preview window (not available on Windows)
```sh
# Using https://iterm2.com/utilities/imgcat
fzf --preview 'imgcat -W $FZF_PREVIEW_COLUMNS -H $FZF_PREVIEW_LINES {}'
```
- HTTP server can be configured to accept remote connections
```sh
# FZF_API_KEY is required for a non-localhost listen address
export FZF_API_KEY="$(head -c 32 /dev/urandom | base64)"
fzf --listen 0.0.0.0:6266
```
- To allow remote process execution, use `--listen-unsafe` instead
(`execute*`, `reload*`, `become`, `preview`, `change-preview`, `transform-*`)
```sh
fzf --listen-unsafe 0.0.0.0:6266
```
- Bug fixes
0.43.0
------
- (Experimental) Added support for Kitty image protocol in the preview window
(not available on Windows)
```sh
fzf --preview='
if file --mime-type {} | grep -qF image/; then
# --transfer-mode=memory is the fastest option but if you want fzf to be able
# to redraw the image on terminal resize or on 'change-preview-window',
# you need to use --transfer-mode=stream.
kitty icat --clear --transfer-mode=memory --unicode-placeholder --stdin=no --place=${FZF_PREVIEW_COLUMNS}x${FZF_PREVIEW_LINES}@0x0 {} | sed \$d
else
bat --color=always {}
fi
'
```
- (Experimental) `--listen` server can report program state in JSON format (`GET /`)
```sh
# fzf server started in "headless" mode
fzf --listen 6266 2> /dev/null
# Get program state
curl localhost:6266 | jq .
# Increase the number of items returned (default: 100)
curl localhost:6266?limit=1000 | jq .
```
- `--listen` server can be secured by setting `$FZF_API_KEY` environment
variable.
```sh
export FZF_API_KEY="$(head -c 32 /dev/urandom | base64)"
# Server
fzf --listen 6266
# Client
curl localhost:6266 -H "x-api-key: $FZF_API_KEY" -d 'change-query(yo)'
```
- Added `toggle-header` action
- Added mouse events for `--bind`
- `scroll-up` (bound to `up`)
- `scroll-down` (bound to `down`)
- `shift-scroll-up` (bound to `toggle+up`)
- `shift-scroll-down` (bound to `toggle+down`)
- `shift-left-click` (bound to `toggle`)
- `shift-right-click` (bound to `toggle`)
- `preview-scroll-up` (bound to `preview-up`)
- `preview-scroll-down` (bound to `preview-down`)
```sh
# Twice faster scrolling both in the main window and the preview window
fzf --bind 'scroll-up:up+up,scroll-down:down+down' \
--bind 'preview-scroll-up:preview-up+preview-up' \
--bind 'preview-scroll-down:preview-down+preview-down' \
--preview 'cat {}'
```
- Added `offset-up` and `offset-down` actions
```sh
# Scrolling will behave similarly to CTRL-E and CTRL-Y of vim
fzf --bind scroll-up:offset-up,scroll-down:offset-down \
--bind ctrl-y:offset-up,ctrl-e:offset-down \
--scroll-off=5
```
- Shell extensions
- Updated bash completion for fzf options
- bash key bindings no longer requires perl; it will use awk or mawk
instead if perl is not found
- Basic context-aware completion for ssh command
- Applied `--scheme=path` for better ordering of the result
- Bug fixes and improvements
0.42.0
------
- Added new info style: `--info=right`
- Added new info style: `--info=inline-right`
- Added new border style `thinblock` which uses symbols for legacy computing
[one eighth block elements](https://en.wikipedia.org/wiki/Symbols_for_Legacy_Computing)
- Similarly to `block`, this style is suitable when using a different
background color because the window is completely contained within the border.
```sh
BAT_THEME=GitHub fzf --info=right --border=thinblock --preview-window=border-thinblock \
--margin=3 --scrollbar=▏▕ --preview='bat --color=always --style=numbers {}' \
--color=light,query:238,fg:238,bg:251,bg+:249,gutter:251,border:248,preview-bg:253
```
- This style may not render correctly depending on the font and the
terminal emulator.
0.41.1
------
- Fixed a bug where preview window is not updated when `--disabled` is set and
a reload is triggered by `change:reload` binding
0.41.0
------
- Added color name `preview-border` and `preview-scrollbar`
- Added new border style `block` which uses [block elements](https://en.wikipedia.org/wiki/Block_Elements)
- `--scrollbar` can take two characters, one for the main window, the other
for the preview window
- Putting it altogether:
```sh
fzf-tmux -p 80% --padding 1,2 --preview 'bat --style=plain --color=always {}' \
--color 'bg:237,bg+:235,gutter:237,border:238,scrollbar:236' \
--color 'preview-bg:235,preview-border:236,preview-scrollbar:234' \
--preview-window 'border-block' --border block --scrollbar '▌▐'
```
- Bug fixes and improvements
0.40.0
------
- Added `zero` event that is triggered when there's no match
```sh
# Reload the candidate list when there's no match
echo $RANDOM | fzf --bind 'zero:reload(echo $RANDOM)+clear-query' --height 3
```
- New actions
- Added `track` action which makes fzf track the current item when the
search result is updated. If the user manually moves the cursor, or the
item is not in the updated search result, tracking is automatically
disabled. Tracking is useful when you want to see the surrounding items
by deleting the query string.
```sh
# Narrow down the list with a query, point to a command,
# and hit CTRL-T to see its surrounding commands.
export FZF_CTRL_R_OPTS="
--preview 'echo {}' --preview-window up:3:hidden:wrap
--bind 'ctrl-/:toggle-preview'
--bind 'ctrl-t:track+clear-query'
--bind 'ctrl-y:execute-silent(echo -n {2..} | pbcopy)+abort'
--color header:italic
--header 'Press CTRL-Y to copy command into clipboard'"
```
- Added `change-header(...)`
- Added `transform-header(...)`
- Added `toggle-track` action
- Fixed `--track` behavior when used with `--tac`
- However, using `--track` with `--tac` is not recommended. The resulting
behavior can be very confusing.
- Bug fixes and improvements
0.39.0
------
- Added `one` event that is triggered when there's only one match
```sh
# Automatically select the only match
seq 10 | fzf --bind one:accept
```
- Added `--track` option that makes fzf track the current selection when the
result list is updated. This can be useful when browsing logs using fzf with
sorting disabled.
```sh
git log --oneline --graph --color=always | nl |
fzf --ansi --track --no-sort --layout=reverse-list
```
- If you use `--listen` option without a port number fzf will automatically
allocate an available port and export it as `$FZF_PORT` environment
variable.
```sh
# Automatic port assignment
fzf --listen --bind 'start:execute-silent:echo $FZF_PORT > /tmp/fzf-port'
# Say hello
curl "localhost:$(cat /tmp/fzf-port)" -d 'preview:echo Hello, fzf is listening on $FZF_PORT.'
```
- A carriage return and a line feed character will be rendered as dim ␍ and
␊ respectively.
```sh
printf "foo\rbar\nbaz" | fzf --read0 --preview 'echo {}'
```
- fzf will stop rendering a non-displayable characters as a space. This will
likely cause less glitches in the preview window.
```sh
fzf --preview 'head -1000 /dev/random'
```
- Bug fixes and improvements
0.38.0
------
- New actions
- `become(...)` - Replace the current fzf process with the specified
command using `execve(2)` system call.
See https://github.com/junegunn/fzf#turning-into-a-different-process for
more information.
```sh
# Open selected files in Vim
fzf --multi --bind 'enter:become(vim {+})'
# Open the file in Vim and go to the line
git grep --line-number . |
fzf --delimiter : --nth 3.. --bind 'enter:become(vim {1} +{2})'
```
- This action is not supported on Windows
- `show-preview`
- `hide-preview`
- Bug fixes
- `--preview-window 0,hidden` should not execute the preview command until
`toggle-preview` action is triggered
0.37.0
------
- Added a way to customize the separator of inline info
```sh
fzf --info 'inline: ╱ ' --prompt '╱ ' --color prompt:bright-yellow
```
- New event
- `focus` - Triggered when the focus changes due to a vertical cursor
movement or a search result update
```sh
fzf --bind 'focus:transform-preview-label:echo [ {} ]' --preview 'cat {}'
# Any action bound to the event runs synchronously and thus can make the interface sluggish
# e.g. lolcat isn't one of the fastest programs, and every cursor movement in
# fzf will be noticeably affected by its execution time
fzf --bind 'focus:transform-preview-label:echo [ {} ] | lolcat -f' --preview 'cat {}'
# Beware not to introduce an infinite loop
seq 10 | fzf --bind 'focus:up' --cycle
```
- New actions
- `change-border-label`
- `change-preview-label`
- `transform-border-label`
- `transform-preview-label`
- Bug fixes and improvements
0.36.0
------
- Added `--listen=HTTP_PORT` option to start HTTP server. It allows external
processes to send actions to perform via POST method.
```sh
# Start HTTP server on port 6266
fzf --listen 6266
# Send actions to the server
curl -XPOST localhost:6266 -d 'reload(seq 100)+change-prompt(hundred> )'
```
- Added draggable scrollbar to the main search window and the preview window
```sh
# Hide scrollbar
fzf --no-scrollbar
# Customize scrollbar
fzf --scrollbar ┆ --color scrollbar:blue
```
- New event
- Added `load` event that is triggered when the input stream is complete
and the initial processing of the list is complete.
```sh
# Change the prompt to "loaded" when the input stream is complete
(seq 10; sleep 1; seq 11 20) | fzf --prompt 'Loading> ' --bind 'load:change-prompt:Loaded> '
# You can use it instead of 'start' event without `--sync` if asynchronous
# trigger is not an issue.
(seq 10; sleep 1; seq 11 20) | fzf --bind 'load:last'
```
- New actions
- Added `pos(...)` action to move the cursor to the numeric position
- `first` and `last` are equivalent to `pos(1)` and `pos(-1)` respectively
```sh
# Put the cursor on the 10th item
seq 100 | fzf --sync --bind 'start:pos(10)'
# Put the cursor on the 10th to last item
seq 100 | fzf --sync --bind 'start:pos(-10)'
```
- Added `reload-sync(...)` action which replaces the current list only after
the reload process is complete. This is useful when the command takes
a while to produce the initial output and you don't want fzf to run against
an empty list while the command is running.
```sh
# You can still filter and select entries from the initial list for 3 seconds
seq 100 | fzf --bind 'load:reload-sync(sleep 3; seq 1000)+unbind(load)'
```
- Added `next-selected` and `prev-selected` actions to move between selected
items
```sh
# `next-selected` will move the pointer to the next selected item below the current line
# `prev-selected` will move the pointer to the previous selected item above the current line
seq 10 | fzf --multi --bind ctrl-n:next-selected,ctrl-p:prev-selected
# Both actions respect --layout option
seq 10 | fzf --multi --bind ctrl-n:next-selected,ctrl-p:prev-selected --layout reverse
```
- Added `change-query(...)` action that simply changes the query string to the
given static string. This can be useful when used with `--listen`.
```sh
curl localhost:6266 -d "change-query:$(date)"
```
- Added `transform-prompt(...)` action for transforming the prompt string
using an external command
```sh
# Press space to change the prompt string using an external command
# (only the first line of the output is taken)
fzf --bind 'space:reload(ls),load:transform-prompt(printf "%s> " "$(date)")'
```
- Added `transform-query(...)` action for transforming the query string using
an external command
```sh
# Press space to convert the query to uppercase letters
fzf --bind 'space:transform-query(tr "[:lower:]" "[:upper:]" <<< {q})'
# Bind it to 'change' event for automatic conversion
fzf --bind 'change:transform-query(tr "[:lower:]" "[:upper:]" <<< {q})'
# Can only type numbers
fzf --bind 'change:transform-query(sed "s/[^0-9]//g" <<< {q})'
```
- `put` action can optionally take an argument string
```sh
# a will put 'alpha' on the prompt, ctrl-b will put 'bravo'
fzf --bind 'a:put+put(lpha),ctrl-b:put(bravo)'
```
- Added color name `preview-label` for `--preview-label` (defaults to `label`
for `--border-label`)
- Better support for (Windows) terminals where each box-drawing character
takes 2 columns. Set `RUNEWIDTH_EASTASIAN` environment variable to `0` or `1`.
- On Vim, the variable will be automatically set if `&ambiwidth` is `double`
- Behavior changes
- fzf will always execute the preview command if the command template
contains `{q}` even when it's empty. If you prefer the old behavior,
you'll have to check if `{q}` is empty in your command.
```sh
# This will show // even when the query is empty
: | fzf --preview 'echo /{q}/'
# But if you don't want it,
: | fzf --preview '[ -n {q} ] || exit; echo /{q}/'
```
- `double-click` will behave the same as `enter` unless otherwise specified,
so you don't have to repeat the same action twice in `--bind` in most cases.
```sh
# No need to bind 'double-click' to the same action
fzf --bind 'enter:execute:less {}' # --bind 'double-click:execute:less {}'
```
- If the color for `separator` is not specified, it will default to the
color for `border`. Same holds true for `scrollbar`. This is to reduce
the number of configuration items required to achieve a consistent color
scheme.
- If `follow` flag is specified in `--preview-window` option, fzf will
automatically scroll to the bottom of the streaming preview output. But
when the user manually scrolls the window, the following stops. With
this version, fzf will resume following if the user scrolls the window
to the bottom.
- Default border style on Windows is changed to `sharp` because some
Windows terminals are not capable of displaying `rounded` border
characters correctly.
- Minor bug fixes and improvements
0.35.1
------
- Fixed a bug where fzf with `--tiebreak=chunk` crashes on inverse match query
- Fixed a bug where clicking above fzf would paste escape sequences
0.35.0
------
- Added `start` event that is triggered only once when fzf finder starts.
Since fzf consumes the input stream asynchronously, the input list is not
available unless you use `--sync`.
```sh
seq 100 | fzf --multi --sync --bind 'start:last+select-all+preview(echo welcome)'
```
- Added `--border-label` and `--border-label-pos` for putting label on the border
```sh
# ANSI color codes are supported
# (with https://github.com/busyloop/lolcat)
label=$(curl -s http://metaphorpsum.com/sentences/1 | lolcat -f)
# Border label at the center
fzf --height=10 --border --border-label="╢ $label ╟" --color=label:italic:black
# Left-aligned (positive integer)
fzf --height=10 --border --border-label="╢ $label ╟" --border-label-pos=3 --color=label:italic:black
# Right-aligned (negative integer) on the bottom line (:bottom)
fzf --height=10 --border --border-label="╢ $label ╟" --border-label-pos=-3:bottom --color=label:italic:black
```
- Also added `--preview-label` and `--preview-label-pos` for the border of the
preview window
```sh
fzf --preview 'cat {}' --border --preview-label=' Preview ' --preview-label-pos=2
```
- Info panel (match counter) will be followed by a horizontal separator by
default
- Use `--no-separator` or `--separator=''` to hide the separator
- You can specify an arbitrary string that is repeated to form the
horizontal separator. e.g. `--separator=╸`
- The color of the separator can be customized via `--color=separator:...`
- ANSI color codes are also supported
```sh
fzf --separator=╸ --color=separator:green
fzf --separator=$(lolcat -f -F 1.4 <<< ▁▁▂▃▄▅▆▆▅▄▃▂▁▁) --info=inline
```
- Added `--border=bold` and `--border=double` along with
`--preview-window=border-bold` and `--preview-window=border-double`
0.34.0
------
- Added support for adaptive `--height`. If the `--height` value is prefixed
with `~`, fzf will automatically determine the height in the range according
to the input size.
```sh
seq 1 | fzf --height ~70% --border --padding 1 --margin 1
seq 10 | fzf --height ~70% --border --padding 1 --margin 1
seq 100 | fzf --height ~70% --border --padding 1 --margin 1
```
- There are a few limitations
- Not compatible with percent top/bottom margin/padding
```sh
# This is not allowed (top/bottom margin in percent value)
fzf --height ~50% --border --margin 5%,10%
# This is allowed (top/bottom margin in fixed value)
fzf --height ~50% --border --margin 2,10%
```
- fzf will not start until it can determine the right height for the input
```sh
# fzf will open immediately
(sleep 2; seq 10) | fzf --height 50%
# fzf will open after 2 seconds
(sleep 2; seq 10) | fzf --height ~50%
(sleep 2; seq 1000) | fzf --height ~50%
```
- Fixed tcell renderer used to render full-screen fzf on Windows
- ~~`--no-clear` is deprecated. Use `reload` action instead.~~
0.33.0
------
- Added `--scheme=[default|path|history]` option to choose scoring scheme
- (Experimental)
- We updated the scoring algorithm in 0.32.0, however we have learned that
this new scheme (`default`) is not always giving the optimal result
- `path`: Additional bonus point is only given to the characters after
path separator. You might want to choose this scheme if you have many
files with spaces in their paths.
- `history`: No additional bonus points are given so that we give more
weight to the chronological ordering. This is equivalent to the scoring
scheme before 0.32.0. This also sets `--tiebreak=index`.
- ANSI color sequences with colon delimiters are now supported.
```sh
printf "\e[38;5;208mOption 1\e[m\nOption 2" | fzf --ansi
printf "\e[38:5:208mOption 1\e[m\nOption 2" | fzf --ansi
```
- Support `border-{up,down}` as the synonyms for `border-{top,bottom}` in
`--preview-window`
- Added support for ANSI `strikethrough`
```sh
printf "\e[9mdeleted" | fzf --ansi
fzf --color fg+:strikethrough
```
0.32.1
------
- Fixed incorrect ordering of `--tiebreak=chunk`
- fzf-tmux will show fzf border instead of tmux popup border (requires tmux 3.3)
```sh
fzf-tmux -p70%
fzf-tmux -p70% --color=border:bright-red
fzf-tmux -p100%,60% --color=border:bright-yellow --border=horizontal --padding 1,5 --margin 1,0
fzf-tmux -p70%,100% --color=border:bright-green --border=vertical
# Key bindings (CTRL-T, CTRL-R, ALT-C) will use these options
export FZF_TMUX_OPTS='-p100%,60% --color=border:green --border=horizontal --padding 1,5 --margin 1,0'
```
0.32.0
------
- Updated the scoring algorithm
- Different bonus points to different categories of word boundaries
(listed higher to lower bonus point)
- Word after whitespace characters or beginning of the string
- Word after common delimiter characters (`/,:;|`)
- Word after other non-word characters
```sh
# foo/bar.sh` is preferred over `foo-bar.sh` on `bar`
fzf --query=bar --height=4 << EOF
foo-bar.sh
foo/bar.sh
EOF
```
- Added a new tiebreak `chunk`
- Favors the line with shorter matched chunk. A chunk is a set of
consecutive non-whitespace characters.
- Unlike the default `length`, this scheme works well with tabular input
```sh
# length prefers item #1, because the whole line is shorter,
# chunk prefers item #2, because the matched chunk ("foo") is shorter
fzf --height=6 --header-lines=2 --tiebreak=chunk --reverse --query=fo << "EOF"
N | Field1 | Field2 | Field3
- | ------ | ------ | ------
1 | hello | foobar | baz
2 | world | foo | bazbaz
EOF
```
- If the input does not contain any spaces, `chunk` is equivalent to
`length`. But we're not going to set it as the default because it is
computationally more expensive.
- Bug fixes and improvements
0.31.0
------
- Added support for an alternative preview window layout that is activated
when the size of the preview window is smaller than a certain threshold.
```sh
# If the width of the preview window is smaller than 50 columns,
# it will be displayed above the search window.
fzf --preview 'cat {}' --preview-window 'right,50%,border-left,<50(up,30%,border-bottom)'
# Or you can just hide it like so
fzf --preview 'cat {}' --preview-window '<50(hidden)'
```
- fzf now uses SGR mouse mode to properly support mouse on larger terminals
- You can now use characters that do not satisfy `unicode.IsGraphic` constraint
for `--marker`, `--pointer`, and `--ellipsis`. Allows Nerd Fonts and stuff.
Use at your own risk.
- Bug fixes and improvements
- Shell extension
- `kill` completion now requires trigger sequence (`**`) for consistency
0.30.0
------
- Fixed cursor flickering over the screen by hiding it during rendering
- Added `--ellipsis` option. You can take advantage of it to make fzf
effectively search non-visible parts of the item.
```sh
# Search against hidden line numbers on the far right
nl /usr/share/dict/words |
awk '{printf "%s%1000s\n", $2, $1}' |
fzf --nth=-1 --no-hscroll --ellipsis='' |
awk '{print $2}'
```
- Added `rebind` action for restoring bindings after `unbind`
- Bug fixes and improvements
0.29.0
------
- Added `change-preview(...)` action to change the `--preview` command
- cf. `preview(...)` is a one-off action that doesn't change the default
preview command
- Added `change-preview-window(...)` action
- You can rotate through the different options separated by `|`
```sh
fzf --preview 'cat {}' --preview-window right:40% \
--bind 'ctrl-/:change-preview-window(right,70%|down,40%,border-top|hidden|)'
```
- Fixed rendering of the prompt line when overflow occurs with `--info=inline`
0.28.0
------
- Added `--header-first` option to print header before the prompt line
```sh
fzf --header $'Welcome to fzf\n▔▔▔▔▔▔▔▔▔▔▔▔▔▔' --reverse --height 30% --border --header-first
```
- Added `--scroll-off=LINES` option (similar to `scrolloff` option of Vim)
- You can set it to a very large number so that the cursor stays in the
middle of the screen while scrolling
```sh
fzf --scroll-off=5
fzf --scroll-off=999
```
- Fixed bug where preview window is not updated on `reload` (#2644)
- fzf on Windows will also use `$SHELL` to execute external programs
- See #2638 and #2647
- Thanks to @rashil2000, @vovcacik, and @janlazo
0.27.3
------
- Preview window is `hidden` by default when there are `preview` bindings but
`--preview` command is not given
- Fixed bug where `{n}` is not properly reset on `reload`
- Fixed bug where spinner is not displayed on `reload`
- Enhancements in tcell renderer for Windows (#2616)
- Vim plugin
- `sinklist` is added as a synonym to `sink*` so that it's easier to add
a function to a spec dictionary
```vim
let spec = { 'source': 'ls', 'options': ['--multi', '--preview', 'cat {}'] }
function spec.sinklist(matches)
echom string(a:matches)
endfunction
call fzf#run(fzf#wrap(spec))
```
- Vim 7 compatibility
0.27.2
------
- 16 base ANSI colors can be specified by their names
```sh
fzf --color fg:3,fg+:11
fzf --color fg:yellow,fg+:bright-yellow
```
- Fix bug where `--read0` not properly displaying long lines
0.27.1
------
- Added `unbind` action. In the following Ripgrep launcher example, you can
use `unbind(reload)` to switch to fzf-only filtering mode.
- See https://github.com/junegunn/fzf/blob/master/ADVANCED.md#switching-to-fzf-only-search-mode
- Vim plugin
- Vim plugin will stop immediately even when the source command hasn't finished
```vim
" fzf will read the stream file while allowing other processes to append to it
call fzf#run({'source': 'cat /dev/null > /tmp/stream; tail -f /tmp/stream'})
```
- It is now possible to open popup window relative to the current window
```vim
let g:fzf_layout = { 'window': { 'width': 0.9, 'height': 0.6, 'relative': v:true, 'yoffset': 1.0 } }
```
0.27.0
------
- More border options for `--preview-window`
```sh
fzf --preview 'cat {}' --preview-window border-left
fzf --preview 'cat {}' --preview-window border-left --border horizontal
fzf --preview 'cat {}' --preview-window top:border-bottom
fzf --preview 'cat {}' --preview-window top:border-horizontal
```
- Automatically set `/dev/tty` as STDIN on execute action
```sh
# Redirect /dev/tty to suppress "Vim: Warning: Input is not from a terminal"
# ls | fzf --bind "enter:execute(vim {} < /dev/tty)"
# "< /dev/tty" part is no longer needed
ls | fzf --bind "enter:execute(vim {})"
```
- Bug fixes and improvements
- Signed and notarized macOS binaries
(Huge thanks to [BACKERS.md](https://github.com/junegunn/junegunn/blob/main/BACKERS.md)!)
0.26.0
------
- Added support for fixed header in preview window
```sh
# Display top 3 lines as the fixed header
fzf --preview 'bat --style=header,grid --color=always {}' --preview-window '~3'
```
- More advanced preview offset expression to better support the fixed header
```sh
# Preview with bat, matching line in the middle of the window below
# the fixed header of the top 3 lines
#
# ~3 Top 3 lines as the fixed header
# +{2} Base scroll offset extracted from the second field
# +3 Extra offset to compensate for the 3-line header
# /2 Put in the middle of the preview area
#
git grep --line-number '' |
fzf --delimiter : \
--preview 'bat --style=full --color=always --highlight-line {2} {1}' \
--preview-window '~3:+{2}+3/2'
```
- Added `select` and `deselect` action for unconditionally selecting or
deselecting a single item in `--multi` mode. Complements `toggle` action.
- Significant performance improvement in ANSI code processing
- Bug fixes and improvements
- Built with Go 1.16
0.25.1
------
- Added `close` action
- Close preview window if open, abort fzf otherwise
- Bug fixes and improvements
0.25.0
------
- Text attributes set in `--color` are not reset when fzf sees another
`--color` option for the same element. This allows you to put custom text
attributes in your `$FZF_DEFAULT_OPTS` and still have those attributes
even when you override the colors.
```sh
# Default colors and attributes
fzf
# Apply custom text attributes
export FZF_DEFAULT_OPTS='--color fg+:italic,hl:-1:underline,hl+:-1:reverse:underline'
fzf
# Different colors but you still have the attributes
fzf --color hl:176,hl+:177
# Write "regular" if you want to clear the attributes
fzf --color hl:176:regular,hl+:177:regular
```
- Renamed `--phony` to `--disabled`
- You can dynamically enable and disable the search functionality using the
new `enable-search`, `disable-search`, and `toggle-search` actions
- You can assign a different color to the query string for when search is disabled
```sh
fzf --color query:#ffffff,disabled:#999999 --bind space:toggle-search
```
- Added `last` action to move the cursor to the last match
- The opposite action `top` is renamed to `first`, but `top` is still
recognized as a synonym for backward compatibility
- Added `preview-top` and `preview-bottom` actions
- Extended support for alt key chords: alt with any case-sensitive single character
```sh
fzf --bind alt-,:first,alt-.:last
```
0.24.4
------
- Added `--preview-window` option `follow`
```sh
# Preview window will automatically scroll to the bottom
fzf --preview-window follow --preview 'for i in $(seq 100000); do
echo "$i"
sleep 0.01
(( i % 300 == 0 )) && printf "\033[2J"
done'
```
- Added `change-prompt` action
```sh
fzf --prompt 'foo> ' --bind $'a:change-prompt:\x1b[31mbar> '
```
- Bug fixes and improvements
0.24.3
------
- Added `--padding` option
```sh
fzf --margin 5% --padding 5% --border --preview 'cat {}' \
--color bg:#222222,preview-bg:#333333
```
0.24.2
------
- Bug fixes and improvements
0.24.1
------
- Fixed broken `--color=[bw|no]` option
0.24.0
------
- Real-time rendering of preview window
```sh
# fzf can render preview window before the command completes
fzf --preview 'sleep 1; for i in $(seq 100); do echo $i; sleep 0.01; done'
# Preview window can process ANSI escape sequence (CSI 2 J) for clearing the display
fzf --preview 'for i in $(seq 100000); do
(( i % 200 == 0 )) && printf "\033[2J"
echo "$i"
sleep 0.01
done'
```
- Updated `--color` option to support text styles
- `regular` / `bold` / `dim` / `underline` / `italic` / `reverse` / `blink`
```sh
# * Set -1 to keep the original color
# * Multiple style attributes can be combined
# * Italic style may not be supported by some terminals
rg --line-number --no-heading --color=always "" |
fzf --ansi --prompt "Rg: " \
--color fg+:italic,hl:underline:-1,hl+:italic:underline:reverse:-1 \
--color pointer:reverse,prompt:reverse,input:159 \
--pointer ' '
```
- More `--border` options
- `vertical`, `top`, `bottom`, `left`, `right`
- Updated Vim plugin to use these new `--border` options
```vim
" Floating popup window in the center of the screen
let g:fzf_layout = { 'window': { 'width': 0.9, 'height': 0.6 } }
" Popup with 100% width
let g:fzf_layout = { 'window': { 'width': 1.0, 'height': 0.5, 'border': 'horizontal' } }
" Popup with 100% height
let g:fzf_layout = { 'window': { 'width': 0.5, 'height': 1.0, 'border': 'vertical' } }
" Similar to 'down' layout, but it uses a popup window and doesn't affect the window layout
let g:fzf_layout = { 'window': { 'width': 1.0, 'height': 0.5, 'yoffset': 1.0, 'border': 'top' } }
" Opens on the right;
" 'highlight' option is still supported but it will only take the foreground color of the group
let g:fzf_layout = { 'window': { 'width': 0.5, 'height': 1.0, 'xoffset': 1.0, 'border': 'left', 'highlight': 'Comment' } }
```
- To indicate if `--multi` mode is enabled, fzf will print the number of
selected items even when no item is selected
```sh
seq 100 | fzf
# 100/100
seq 100 | fzf --multi
# 100/100 (0)
seq 100 | fzf --multi 5
# 100/100 (0/5)
```
- Since 0.24.0, release binaries will be uploaded to https://github.com/junegunn/fzf/releases
0.23.1
------
- Added `--preview-window` options for disabling flags
- `nocycle`
- `nohidden`
- `nowrap`
- `default`
- Built with Go 1.14.9 due to performance regression
- https://github.com/golang/go/issues/40727
0.23.0
------
- Support preview scroll offset relative to window height
```sh
git grep --line-number '' |
fzf --delimiter : \
--preview 'bat --style=numbers --color=always --highlight-line {2} {1}' \
--preview-window +{2}-/2
```
- Added `--preview-window` option for sharp edges (`--preview-window sharp`)
- Added `--preview-window` option for cyclic scrolling (`--preview-window cycle`)
- Reduced vertical padding around the preview window when `--preview-window
noborder` is used
- Added actions for preview window
- `preview-half-page-up`
- `preview-half-page-down`
- Vim
- Popup width and height can be given in absolute integer values
- Added `fzf#exec()` function for getting the path of fzf executable
- It also downloads the latest binary if it's not available by running
`./install --bin`
- Built with Go 1.15.2
- We no longer provide 32-bit binaries
0.22.0
------
- Added more options for `--bind`
- `backward-eof` event
```sh
# Aborts when you delete backward when the query prompt is already empty
fzf --bind backward-eof:abort
```
- `refresh-preview` action
```sh
# Rerun preview command when you hit '?'
fzf --preview 'echo $RANDOM' --bind '?:refresh-preview'
```
- `preview` action
```sh
# Default preview command with an extra preview binding
fzf --preview 'file {}' --bind '?:preview:cat {}'
# A preview binding with no default preview command
# (Preview window is initially empty)
fzf --bind '?:preview:cat {}'
# Preview window hidden by default, it appears when you first hit '?'
fzf --bind '?:preview:cat {}' --preview-window hidden
```
- Added preview window option for setting the initial scroll offset
```sh
# Initial scroll offset is set to the line number of each line of
# git grep output *minus* 5 lines
git grep --line-number '' |
fzf --delimiter : --preview 'nl {1}' --preview-window +{2}-5
```
- Added support for ANSI colors in `--prompt` string
- Smart match of accented characters
- An unaccented character in the query string will match both accented and
unaccented characters, while an accented character will only match
accented characters. This is similar to how "smart-case" match works.
- Vim plugin
- `tmux` layout option for using fzf-tmux
```vim
let g:fzf_layout = { 'tmux': '-p90%,60%' }
```
0.21.1
------
- Shell extension
- CTRL-R will remove duplicate commands
- fzf-tmux
- Supports tmux popup window (require tmux 3.2 or above)
- ```sh
# 50% width and height
fzf-tmux -p
# 80% width and height
fzf-tmux -p 80%
# 80% width and 40% height
fzf-tmux -p 80%,40%
fzf-tmux -w 80% -h 40%
# Window position
fzf-tmux -w 80% -h 40% -x 0 -y 0
fzf-tmux -w 80% -h 40% -y 1000
# Write ordinary fzf options after --
fzf-tmux -p -- --reverse --info=inline --margin 2,4 --border
```
- On macOS, you can build the latest tmux from the source with
`brew install tmux --HEAD`
- Bug fixes
- Fixed Windows file traversal not to include directories
- Fixed ANSI colors with `--keep-right`
- Fixed _fzf_complete for zsh
- Built with Go 1.14.1
0.21.0
------
- `--height` option is now available on Windows as well (@kelleyma49)
- Added `--pointer` and `--marker` options
- Added `--keep-right` option that keeps the right end of the line visible
when it's too long
- Style changes
- `--border` will now print border with rounded corners around the
finder instead of printing horizontal lines above and below it.
The previous style is available via `--border=horizontal`
- Unicode spinner
- More keys and actions for `--bind`
- Added PowerShell script for downloading Windows binary
- Vim plugin: Built-in floating windows support
```vim
let g:fzf_layout = { 'window': { 'width': 0.9, 'height': 0.6 } }
```
- bash: Various improvements in key bindings (CTRL-T, CTRL-R, ALT-C)
- CTRL-R will start with the current command-line as the initial query
- CTRL-R properly supports multi-line commands
- Fuzzy completion API changed
```sh
# Previous: fzf arguments given as a single string argument
# - This style is still supported, but it's deprecated
_fzf_complete "--multi --reverse --prompt=\"doge> \"" "$@" < <(
echo foo
)
# New API: multiple fzf arguments before "--"
# - Easier to write multiple options
_fzf_complete --multi --reverse --prompt="doge> " -- "$@" < <(
echo foo
)
```
- Bug fixes and improvements
0.20.0
------
- Customizable preview window color (`preview-fg` and `preview-bg` for `--color`)
```sh
fzf --preview 'cat {}' \
--color 'fg:#bbccdd,fg+:#ddeeff,bg:#334455,preview-bg:#223344,border:#778899' \
--border --height 20 --layout reverse --info inline
```
- Removed the immediate flicking of the screen on `reload` action.
```sh
: | fzf --bind 'change:reload:seq {q}' --phony
```
- Added `clear-query` and `clear-selection` actions for `--bind`
- It is now possible to split a composite bind action over multiple `--bind`
expressions by prefixing the later ones with `+`.
```sh
fzf --bind 'ctrl-a:up+up'
# Can be now written as
fzf --bind 'ctrl-a:up' --bind 'ctrl-a:+up'
# This is useful when you need to write special execute/reload form (i.e. `execute:...`)
# to avoid parse errors and add more actions to the same key
fzf --multi --bind 'ctrl-l:select-all+execute:less {+f}' --bind 'ctrl-l:+deselect-all'
```
- Fixed parse error of `--bind` expression where concatenated execute/reload
action contains `+` character.
```sh
fzf --multi --bind 'ctrl-l:select-all+execute(less {+f})+deselect-all'
```
- Fixed bugs of reload action
- Not triggered when there's no match even when the command doesn't have
any placeholder expressions
- Screen not properly cleared when `--header-lines` not filled on reload
0.19.0
------
- Added `--phony` option which completely disables search functionality.
Useful when you want to use fzf only as a selector interface. See below.
- Added "reload" action for dynamically updating the input list without
restarting fzf. See https://github.com/junegunn/fzf/issues/1750 to learn
more about it.
```sh
# Using fzf as the selector interface for ripgrep
RG_PREFIX="rg --column --line-number --no-heading --color=always --smart-case "
INITIAL_QUERY="foo"
FZF_DEFAULT_COMMAND="$RG_PREFIX '$INITIAL_QUERY' || true" \
fzf --bind "change:reload:$RG_PREFIX {q} || true" \
--ansi --phony --query "$INITIAL_QUERY"
```
- `--multi` now takes an optional integer argument which indicates the maximum
number of items that can be selected
```sh
seq 100 | fzf --multi 3 --reverse --height 50%
```
- If a placeholder expression for `--preview` and `execute` action (and the
new `reload` action) contains `f` flag, it is replaced to the
path of a temporary file that holds the evaluated list. This is useful
when you multi-select a large number of items and the length of the
evaluated string may exceed [`ARG_MAX`][argmax].
```sh
# Press CTRL-A to select 100K items and see the sum of all the numbers
seq 100000 | fzf --multi --bind ctrl-a:select-all \
--preview "awk '{sum+=\$1} END {print sum}' {+f}"
```
- `deselect-all` no longer deselects unmatched items. It is now consistent
with `select-all` and `toggle-all` in that it only affects matched items.
- Due to the limitation of bash, fuzzy completion is enabled by default for
a fixed set of commands. A helper function for easily setting up fuzzy
completion for any command is now provided.
```sh
# usage: _fzf_setup_completion path|dir COMMANDS...
_fzf_setup_completion path git kubectl
```
- Info line style can be changed by `--info=STYLE`
- `--info=default`
- `--info=inline` (same as old `--inline-info`)
- `--info=hidden`
- Preview window border can be disabled by adding `noborder` to
`--preview-window`.
- When you transform the input with `--with-nth`, the trailing white spaces
are removed.
- `ctrl-\`, `ctrl-]`, `ctrl-^`, and `ctrl-/` can now be used with `--bind`
- See https://github.com/junegunn/fzf/milestone/15?closed=1 for more details

- Better error messages when the default command or `$FZF_DEFAULT_COMMAND`
fails.
- Reverted #1061 to avoid having duplicate entries in the list when find
command detected a file system loop (#1120). The default command now
requires that find supports `-fstype` option.
- fzf now distinguishes mouse left click and right click (#1130)
- Right click is now bound to `toggle` action by default
- `--bind` understands `left-click` and `right-click`
- Added `replace-query` action (#1137)
- Replaces query string with the current selection
- Added `accept-non-empty` action (#1162)
- Same as accept, except that it prevents fzf from exiting without any
selection

optionally take `+` flag to be used with multiple selections
- e.g. `git log --oneline | fzf --multi --preview 'git show {+1}'`
- Added `execute-silent` action for executing a command silently without
switching to the alternate screen. This is useful when the process is
short-lived and you're not interested in its output.
- e.g. `fzf --bind 'ctrl-y:execute!(echo -n {} | pbcopy)'`
- `ctrl-space` is allowed in `--bind`

chained using `+` separator.
- e.g. `fzf --bind 'ctrl-y:execute(echo -n {} | pbcopy)+abort'`
- `--preview-window` with size 0 is allowed. This is used to make fzf execute
preview command in the background without displaying the result.

color
- Added `half-page-up` and `half-page-down` actions
- Added `-L` flag to the default find command
0.16.0
------
- *Added `--height HEIGHT[%]` option*
- fzf can now display finder without occupying the full screen
- Preview window will truncate long lines by default. Line wrap can be enabled
by `:wrap` flag in `--preview-window`.
- Latin script letters will be normalized before matching so that it's easier
to match against accented letters. e.g. `sodanco` can match `Só Danço Samba`.
- Normalization can be disabled via `--literal`
- Added `--filepath-word` to make word-wise movements/actions (`alt-b`,
`alt-f`, `alt-bs`, `alt-d`) respect path separators

------
- Fixed rendering glitches introduced in 0.15.8
- The default escape delay is reduced to 50ms and is configurable via
`$ESCDELAY`
- Scroll indicator at the top-right corner of the preview window is always
displayed when there's overflow
- Can now be built with ncurses 6 or tcell to support extra features
- *ncurses 6*
- Supports more than 256 color pairs

- Improved escape sequence processing for WSL
- Added support for `alt-[0-9]`, `f11`, and `f12` for `--bind` and `--expect`
0.15.7
------
- Fixed panic when color is disabled and header lines contain ANSI colors
0.15.6
------
- Windows binaries! (@kelleyma49)
- Fixed the bug where header lines are cleared when preview window is toggled
- Fixed not to display ^N and ^O on screen
- Fixed cursor keys (or any key sequence that starts with ESC) on WSL by
making fzf wait for additional keystrokes after ESC for up to 100ms
0.15.5
------
- Setting foreground color will no longer set background color to black
- e.g. `fzf --color fg:153`
- `--tiebreak=end` will consider relative position instead of absolute distance
- Updated `fzf#wrap` function to respect `g:fzf_colors`
0.15.4
------
- Added support for range expression in preview and execute action
- e.g. `ls -l | fzf --preview="echo user={3} when={-4..-2}; cat {-1}" --header-lines=1`
- `{q}` will be replaced to the single-quoted string of the current query
- Fixed to properly handle unicode whitespace characters
- Display scroll indicator in preview window
- Inverse search term will use exact matcher by default
- This is a breaking change, but I believe it makes much more sense. It is
almost impossible to predict which entries will be filtered out due to
a fuzzy inverse term. You can still perform inverse-fuzzy-match by
prepending `!'` to the term.
0.15.3
------
- Added support for more ANSI attributes: dim, underline, blink, and reverse
- Fixed race condition in `toggle-preview`
0.15.2

which values the search performance over the quality of the result
- Advanced scoring criteria
- `--read0` to read input delimited by ASCII NUL character
- `--print0` to print output delimited by ASCII NUL character
0.13.5
------
- Memory and performance optimization
- Up to 2x performance with half the amount of memory
0.13.4
------
- Performance optimization
- Memory footprint for ascii string is reduced by 60%
- 15 to 20% improvement of query performance
- Up to 45% better performance of `--nth` with non-regex delimiters
- Fixed invalid handling of `hidden` property of `--preview-window`
0.13.3
------
- Fixed duplicate rendering of the last line in preview window
0.13.2
------

0.13.1
------
- Fixed UI issue with large `--preview` output with many ANSI codes
0.13.0
------

- `--preview CMD`
- `--preview-window POS[:SIZE][:hidden]`
- `{}` in execute action is now replaced to the single-quoted (instead of
double-quoted) string of the current line
- Fixed to ignore control characters for bracketed paste mode
0.12.2
------
- 256-color capability detection does not require `256` in `$TERM`
- Added `print-query` action
- More named keys for binding; <kbd>F1</kbd> ~ <kbd>F10</kbd>,
<kbd>ALT-/</kbd>, <kbd>ALT-space</kbd>, and <kbd>ALT-enter</kbd>
- Added `jump` and `jump-accept` actions that implement [EasyMotion][em]-like
movement

0.12.1
------
- Ranking algorithm introduced in 0.12.0 is now universally applied
- Fixed invalid cache reference in exact mode
- Fixes and improvements in Vim plugin and shell extensions
0.12.0
------
- Enhanced ranking algorithm
- Minor bug fixes
0.11.4
------
- Added `--hscroll-off=COL` option (default: 10) (#513)
- Some fixes in Vim plugin and shell extensions
0.11.3
------
- Graceful exit on SIGTERM (#482)
- `$SHELL` instead of `sh` for `execute` action and `$FZF_DEFAULT_COMMAND` (#481)
- Changes in fuzzy completion API
- [`_fzf_compgen_{path,dir}`](https://github.com/junegunn/fzf/commit/9617647)
- [`_fzf_complete_COMMAND_post`](https://github.com/junegunn/fzf/commit/8206746)
for post-processing
0.11.2
------
- `--tiebreak` now accepts comma-separated list of sort criteria
- Each criterion should appear only once in the list
- `index` is only allowed at the end of the list
- `index` is implicitly appended to the list when not specified
- Default is `length` (or equivalently `length,index`)
- `begin` criterion will ignore leading whitespaces when calculating the index
- Added `toggle-in` and `toggle-out` actions
- Switch direction depending on `--reverse`-ness
- `export FZF_DEFAULT_OPTS="--bind tab:toggle-out,shift-tab:toggle-in"`
- Reduced the initial delay when `--tac` is not given
- fzf defers the initial rendering of the screen up to 100ms if the input
stream is ongoing to prevent unnecessary redraw during the initial
phase. However, 100ms delay is quite noticeable and might give the
impression that fzf is not snappy enough. This commit reduces the
maximum delay down to 20ms when `--tac` is not specified, in which case
the input list quickly fills the entire screen.
0.11.1
------
- Added `--tabstop=SPACES` option
0.11.0
------
- Added OR operator for extended-search mode
- Added `--execute-multi` action
- Fixed incorrect cursor position when unicode wide characters are used in
`--prompt`
- Fixes and improvements in shell extensions
0.10.9
------
- Extended-search mode is now enabled by default
- `--extended-exact` is deprecated and instead we have `--exact` for
orthogonally controlling "exactness" of search
- Fixed not to display non-printable characters
- Added `double-click` for `--bind` option
- More robust handling of SIGWINCH
0.10.8
------
- Fixed panic when trying to set colors after colors are disabled (#370)
0.10.7
------
- Fixed unserialized interrupt handling during execute action which often
caused invalid memory access and crash
- Changed `--tiebreak=length` (default) to use trimmed length when `--nth` is
used
0.10.6
------
- Replaced `--header-file` with `--header` option
- `--header` and `--header-lines` can be used together
- Changed exit status
- 0: Okay
- 1: No match
- 2: Error
- 130: Interrupted
- 64-bit linux binary is statically-linked with ncurses to avoid
compatibility issues.
0.10.5
------
- `'`-prefix to unquote the term in `--extended-exact` mode
- Backward scan when `--tiebreak=end` is set
0.10.4
------
- Fixed to remove ANSI code from output when `--with-nth` is set
0.10.3
------
- Fixed slow performance of `--with-nth` when used with `--delimiter`
- Regular expression engine of Golang as of now is very slow, so the fixed
version will treat the given delimiter pattern as a plain string instead
of a regular expression unless it contains special characters and is
a valid regular expression.
- Simpler regular expression for delimiter for better performance
0.10.2
------
### Fixes and improvements
- Improvement in perceived response time of queries
- Eager, efficient rune array conversion
- Graceful exit when failed to initialize ncurses (invalid $TERM)
- Improved ranking algorithm when `--nth` option is set
- Changed the default command not to fail when there are files whose names
start with dash
0.10.1
------
### New features
- Added `--margin` option
- Added options for sticky header
- `--header-file`
- `--header-lines`
- Added `cancel` action which clears the input or closes the finder when the
input is already empty

- Added `delete-char/eof` action to differentiate `CTRL-D` and `DEL`
### Minor improvements/fixes
- Fixed to allow binding colon and comma keys
- Fixed ANSI processor to handle color regions spanning multiple lines
0.10.0
------
### New features
- More actions for `--bind`
- `select-all`
- `deselect-all`
- `toggle-all`
- `ignore`
- `execute(...)` action for running arbitrary command without leaving fzf
- `fzf --bind "ctrl-m:execute(less {})"`
- `fzf --bind "ctrl-t:execute(tmux new-window -d 'vim {}')"`
- If the command contains parentheses, use any of the follows alternative
notations to avoid parse errors
- `execute[...]`
- `execute~...~`
- `execute!...!`
- `execute@...@`
- `execute#...#`
- `execute$...$`
- `execute%...%`
- `execute^...^`
- `execute&...&`
- `execute*...*`
- `execute;...;`
- `execute/.../`
- `execute|...|`
- `execute:...`
- This is the special form that frees you from parse errors as it
does not expect the closing character
- The catch is that it should be the last one in the
comma-separated list
- Added support for optional search history
- `--history HISTORY_FILE`
- When used, `CTRL-N` and `CTRL-P` are automatically remapped to
`next-history` and `previous-history`
- `--history-size MAX_ENTRIES` (default: 1000)
- Cyclic scrolling can be enabled with `--cycle`
- Fixed the bug where the spinner was not spinning on idle input stream
- e.g. `sleep 100 | fzf`

- e.g. `let $FZF_DEFAULT_OPTS = $FZF_DEFAULT_OPTS.' --inline-info'`
### Bug fixes
- Invalid mutation of input on case conversion (#209)
- Smart-case for each term in extended-search mode (#208)
- Fixed double-click result when scroll offset is positive

`--select-1` or `--exit-0` (#172)
- Fixed to allow comma character as an argument to `--expect` option
0.9.6
-----
### New features
#### Added `--expect` option (#163)
If you provide a comma-separated list of keys with `--expect` option, fzf will
allow you to select the match and complete the finder when any of the keys is
pressed. Additionally, fzf will print the name of the key pressed as the first
line of the output so that your script can decide what to do next based on the
information.
```sh
fzf --expect=ctrl-v,ctrl-t,alt-s,f1,f2,~,@
```
The updated vim plugin uses this option to implement
[ctrlp](https://github.com/kien/ctrlp.vim)-compatible key bindings.
### Bug fixes
- Fixed to ignore ANSI escape code `\e[K` (#162)
0.9.5
-----
### New features
#### Added `--ansi` option (#150)
If you give `--ansi` option to fzf, fzf will interpret ANSI color codes from
the input, display the item with the ANSI colors (true colors are not
supported), and strips the codes from the output. This option is off by
default as it entails some overhead.
### Improvements
#### Reduced initial memory footprint (#151)
By removing unnecessary copy of pointers, fzf will use significantly smaller
amount of memory when it's started. The difference is hugely noticeable when
the input is extremely large. (e.g. `locate / | fzf`)
### Bug fixes
- Fixed panic on `--no-sort --filter ''` (#149)
0.9.4
-----
### New features
#### Added `--tac` option to reverse the order of the input.
One might argue that this option is unnecessary since we can already put `tac`
or `tail -r` in the command pipeline to achieve the same result. However, the
advantage of `--tac` is that it does not block until the input is complete.
### *Backward incompatible changes*
#### Changed behavior on `--no-sort`
`--no-sort` option will no longer reverse the display order within finder. You
may want to use the new `--tac` option with `--no-sort`.
```
history | fzf +s --tac
```
### Improvements
#### `--filter` will not block when sort is disabled
When fzf works in filtering mode (`--filter`) and sort is disabled
(`--no-sort`), there's no need to block until input is complete. The new
version of fzf will print the matches on-the-fly when the following condition
is met:
--filter TERM --no-sort [--no-tac --no-sync]
or simply:
-f TERM +s
This change removes unnecessary delay in the use cases like the following:
fzf -f xxx +s | head -5
However, in this case, fzf processes the lines sequentially, so it cannot
utilize multiple cores, and fzf will run slightly slower than the previous
mode of execution where filtering is done in parallel after the entire input
is loaded. If the user is concerned about this performance problem, one can
add `--sync` option to re-enable buffering.
0.9.3
-----
### New features
- Added `--sync` option for multi-staged filtering
### Improvements
- `--select-1` and `--exit-0` will start finder immediately when the condition
cannot be met
