fzf/CHANGELOG.md

CHANGELOG

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)

• 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.

• 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)'

• 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

0.13.2

• Fixed race condition where preview window is not properly cleared

0.13.1

• Fixed UI issue with large --preview output with many ANSI codes

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

  • --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

• 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 to allow ^pattern$ in extended-search mode

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
