0.43.0

• (Experimental) Added support for Kitty image protocol in the preview window (currently not supported on Windows)

  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 --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 /)

  # 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.

  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)

  # 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

  # 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
  • Similarly to block, this style is suitable when using a different background color because the window is completely contained within the border.
  • This style may not render correctly depending on the font and the terminal emulator.
  • thinblock

    • 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

      
  • block

    • BAT_THEME=GitHub fzf --info=right --border=block --preview-window=border-block \
          --margin=3 --scrollbar=▌▐ --separator=━ --preview='bat --color=always --style=numbers {}' \
          --color=light,query:238,fg:238,bg:251,bg+:249,gutter:251,border:248,preview-bg:253,preview-border:252

      

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

• --scrollbar can take two characters, one for the main window, the other
  for the preview window

• Putting it altogether:

  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
• 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.

    # 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

  # 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.

  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.

  # 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.

  printf "foo\rbar\nbaz" | fzf --read0 --preview 'echo {}'

• fzf will stop rendering a non-displayable character as a space. This will
  likely cause less glitches in the preview window.

  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.

    # 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

  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

    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.

  # Start HTTP server on port 6266
  fzf --listen 6266
  
  # Send actions to the server
  curl localhost:6266 -d 'reload(seq 100)+change-prompt(hundred> )'

• Added draggable scrollbar to the main search window and the preview window

  # 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.

    # 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

    # 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.

    # 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

    # `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.

    curl localhost:6266 -d "change-query:$(date)"

  • Added transform-prompt(...) action for transforming the prompt string
    using an external command

    # 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

    # 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

    # 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 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.

    # 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.

    # 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
