CHANGELOG
=========

0.16.6
------
- Minor bug fixes and improvements
- Added `--no-clear` option for scripting purposes

0.16.5
------
- Minor bug fixes
- Added `toggle-preview-wrap` action
- Built with Go 1.8

0.16.4
------
- Added `--border` option to draw border above and below the finder
- 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
- Official 24-bit color support
- 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.
- Minor bug fixes and improvements

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
- Preview window will truncate long lines by default. Line wrap can be enabled
  by `:wrap` flag in `--preview-window`.
- 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
------
- Fixed rendering glitches introduced in 0.15.8
- The default escape delay is reduced to 50ms and is configurable via
  `$ESCDELAY`
- Scroll indicator at the top-right corner of the preview window is always
  displayed when there's overflow
- Can now be built with ncurses 6 or tcell to support extra features
    - *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`

0.15.7
------
- Fixed panic when color is disabled and header lines contain ANSI colors

0.15.6
------
- 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
------
- Improved fuzzy search algorithm
    - Added `--algo=[v1|v2]` option so one can still choose the old algorithm
      which values the search performance over the quality of the result
- Advanced scoring criteria
- `--read0` to read input delimited by ASCII NUL character
- `--print0` to print output delimited by ASCII NUL character

0.13.5
------
- Memory and performance optimization
    - Up to 2x performance with half the amount of memory

0.13.4
------
- Performance optimization
    - Memory footprint for ascii string is reduced by 60%
    - 15 to 20% improvement of query performance
    - Up to 45% better performance of `--nth` with non-regex delimiters
- Fixed invalid handling of `hidden` property of `--preview-window`

0.13.3
------
- Fixed duplicate rendering of the last line in preview window

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

0.13.0
------
- 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`
- Added `print-query` action
- More named keys for binding; <kbd>F1</kbd> ~ <kbd>F10</kbd>,
  <kbd>ALT-/</kbd>, <kbd>ALT-space</kbd>, and <kbd>ALT-enter</kbd>
- Added `jump` and `jump-accept` actions that implement [EasyMotion][em]-like
  movement
  ![][jump]

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}`](https://github.com/junegunn/fzf/commit/9617647)
    - [`_fzf_complete_COMMAND_post`](https://github.com/junegunn/fzf/commit/8206746)
      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
------

- Extended-search mode is now enabled by default
    - `--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`
- Added `cancel` action which clears the input or closes the finder when the
  input is already empty
    - e.g. `export FZF_DEFAULT_OPTS="--bind esc:cancel"`
- Added `delete-char/eof` action to differentiate `CTRL-D` and `DEL`

### Minor improvements/fixes

- Fixed to allow binding colon and comma keys
- 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 the bug where the spinner was not spinning on idle input stream
    - e.g. `sleep 100 | fzf`

### Minor improvements/fixes

- Added synonyms for key names that can be specified for `--bind`,
  `--toggle-sort`, and `--expect`
- Fixed the color of multi-select marker on the current line
- Fixed to allow `^pattern$` in extended-search mode

     - 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
------

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.

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

The updated vim plugin uses this option to implement
[ctrlp](https://github.com/kien/ctrlp.vim)-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
