• 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; F1 ~ F10, ALT-/, ALT-space, and ALT-enter
• Added jump and jump-accept actions that implement EasyMotion-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}
  • _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

• 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

• Improvement in perceived response time of queries
  • Eager, efficient rune array conversion

  • select-all
  • deselect-all
  • toggle-all
  • ignore
• execute(...) action for running arbitrary command without leaving fzf
  • fzf --bind "ctrl-m:execute(less {})"

  • 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

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
