fzf/CHANGELOG.md

CHANGELOG

0.37.0

• 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 [ {} ]' --border --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' --border --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 -XPOST 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

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.

  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

  # 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

  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

  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.

  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

      # 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

      # 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.

  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

  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)

  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

    # 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

    # 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.

  # 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.

  # 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 |

    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

  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

    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

    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

  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

    " 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

    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

  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

  # 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!)

0.26.0

• Added support for fixed header in preview window

  # 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

  # 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.

  # 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

  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

  fzf --bind alt-,:first,alt-.:last
  

0.24.4

• Added --preview-window option follow

  # 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

  fzf --prompt 'foo> ' --bind $'a:change-prompt:\x1b[31mbar> '
  

• Bug fixes and improvements

0.24.3

• Added --padding option

  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

  # 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

    # * 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

    " 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

  seq 100 | fzf
    # 100/100
  seq 100 | fzf --multi
    # 100/100 (0)
  seq 100 | fzf --multi 5
    # 100/100 (0/5)

  • 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

  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

    # Aborts when you delete backward when the query prompt is already empty
    fzf --bind backward-eof:abort
    

  • refresh-preview action

    # Rerun preview command when you hit '?'
    fzf --preview 'echo $RANDOM' --bind '?:refresh-preview'
    

  • preview action

    # 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

  # 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

  • Unicode spinner
• More keys and actions for --bind
• Added PowerShell script for downloading Windows binary
• Vim plugin: Built-in floating windows support

  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

  # 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)

  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.

  : | 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 +.

  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.

  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.

  # 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

  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.

  # 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.

  # 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

• More keys for binding: shift-{up,down}, alt-{up,down,left,right}
• fzf can now start even when /dev/tty is not available by making an educated guess.
• Updated the default command for Windows.
• Fixes and improvements on bash/zsh completion
• install and uninstall scripts now supports generating files under XDG_CONFIG_HOME on --xdg flag.

See https://github.com/junegunn/fzf/milestone/12?closed=1 for the full list of changes.

0.17.3

• $LINES and $COLUMNS are exported to preview command so that the command knows the exact size of the preview window.
• 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

• Bug fixes and improvements

0.16.3

• Fixed a bug where fzf incorrectly display the lines when straddling tab characters are trimmed
• Placeholder expression used in --preview and execute action can 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

0.16.2

• Dropped ncurses dependency
• Binaries for freebsd, openbsd, arm5, arm6, arm7, and arm8

• Added support for composite actions in --bind. Multiple actions can be 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.

0.16.1

• Fixed --height option to properly fill the window with the background 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

    • Supports more than 256 color pairs
    • Supports italics
  • tcell
    • 24-bit color support
  • See https://github.com/junegunn/fzf/blob/master/BUILD.md

0.15.8

• Updated ANSI processor to handle more VT-100 escape sequences

• 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

• Preview window is now scrollable
  • With mouse scroll or with bindable actions
    • preview-up
    • preview-down
    • preview-page-up
    • preview-page-down
• Updated ANSI processor to support high intensity colors and ignore some VT100-related escape sequences

0.15.1

• Fixed panic when the pattern occurs after 2^15-th column
• Fixed rendering delay when displaying extremely long lines

0.15.0

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

• 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}
  • _fzf_complete_COMMAND_post 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

• 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

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

0.9.12

New features

• Added --bind option for custom key bindings

Bug fixes

• Fixed to update "inline-info" immediately after terminal resize
• Fixed ANSI code offset calculation

0.9.11

New features

• Added --inline-info option for saving screen estate (#202)
  • Useful inside Neovim
  • 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

0.9.10

Improvements

• Performance optimization
• Less aggressive memoization to limit memory usage

New features

• Added color scheme for light background: --color=light

0.9.9

New features

• Added --tiebreak option (#191)
• Added --no-hscroll option (#193)
• Visual indication of --toggle-sort (#194)

0.9.8

Bug fixes

• Fixed Unicode case handling (#186)
• Fixed to terminate on RuneError (#185)

0.9.7

New features

• Added --toggle-sort option (#173)
  • --toggle-sort=ctrl-r is applied to CTRL-R shell extension

Bug fixes

• Fixed to print empty line if --expect is set and fzf is completed by --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.

fzf --expect=ctrl-v,ctrl-t,alt-s,f1,f2,~,@

The updated vim plugin uses this option to implement ctrlp-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
