• 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

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

• 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

0.15.9

  • ncurses 6
    • 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
• Added --no-bold (and --bold) option
• Improved escape sequence processing for WSL
• Added support for alt-[0-9], f11, and f12 for --bind and --expect

• Windows binaries! (@kelleyma49)
• Fixed the bug where header lines are cleared when preview window is toggled

• 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

• Added preview feature
  • --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

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

• 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

• 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

• 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

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)

0.9.13

New features

• Color customization with the extended --color option

Bug fixes

• Fixed premature termination of Reader in the presence of a long line which is longer than 64KB

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
