Building fzf
|
||||
============
|
||||
|
||||
Build instructions
|
||||
------------------
|
||||
|
||||
### Prerequisites
|
||||
|
||||
- `go` executable in $PATH
|
||||
|
||||
### Using Makefile
|
||||
|
||||
Makefile will set up and use its own `$GOPATH` under the project root.
|
||||
|
||||
```sh
|
||||
# Build fzf binary for your platform in target
|
||||
make
|
||||
|
||||
# Build fzf binary and copy it to bin directory
|
||||
make install
|
||||
|
||||
# Build 32-bit and 64-bit executables and tarballs in target
|
||||
make release
|
||||
|
||||
# Make release archives for all supported platforms in target
|
||||
make release-all
|
||||
```
|
||||
|
||||
### Using `go get`
|
||||
|
||||
Alternatively, you can build fzf directly with `go get` command without
|
||||
manually cloning the repository.
|
||||
|
||||
```sh
|
||||
go get -u github.com/junegunn/fzf
|
||||
```

||||

|
||||
|
||||
0.16.6
|
||||
------
|
||||
- Minor bug fixes and improvements
|
||||

0.16.5
|
||||
------
|
||||

|
||||
|
||||
0.16.4
|

|
||||
- 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

- e.g. `fzf --bind 'ctrl-y:execute!(echo -n {} | pbcopy)'`
|

||||
- 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

|
||||
------
|
||||
- *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 OR operator for extended-search mode
|
||||
- Added `--execute-multi` action

|
||||
`--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
|
||||
|
||||
|
||||

|
||||
|
||||
### Bug fixes

||||
|
||||

|
||||
-----

||||
- `--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

FZF Vim integration
|
||||
===================
|
||||
|
||||
This repository only enables basic integration with Vim. If you're looking for
|
||||
more, check out [fzf.vim](https://github.com/junegunn/fzf.vim) project.
|
||||
|
||||
(Note: To use fzf in GVim, an external terminal emulator is required.)
|
||||
|
||||
`:FZF[!]`
|
||||
---------
|
||||
|
||||
If you have set up fzf for Vim, `:FZF` command will be added.
|
||||
|
||||
```vim
|
||||
" Look for files under current directory
|
||||
:FZF
|
||||
|
||||
" Look for files under your home directory
|
||||
:FZF ~
|
||||
|
||||
" With options
|
||||
:FZF --no-sort --reverse --inline-info /tmp
|
||||
|
||||
" Bang version starts fzf in fullscreen mode
|
||||
:FZF!
|
||||
```
|
||||
|
||||
Similarly to [ctrlp.vim](https://github.com/kien/ctrlp.vim), use enter key,
|
||||
`CTRL-T`, `CTRL-X` or `CTRL-V` to open selected files in the current window,
|
||||
in new tabs, in horizontal splits, or in vertical splits respectively.
|
||||
|
||||
Note that the environment variables `FZF_DEFAULT_COMMAND` and
|
||||
`FZF_DEFAULT_OPTS` also apply here.
|
||||
|
||||
### Configuration
|
||||
|
||||
- `g:fzf_action`
|
||||
- Customizable extra key bindings for opening selected files in different ways
|
||||
- `g:fzf_layout`
|
||||
- Determines the size and position of fzf window
|

#### Examples
|
||||
|
||||
```vim
|
||||
" This is the default extra key bindings
|
||||
let g:fzf_action = {
|
||||
\ 'ctrl-t': 'tab split',
|
||||
\ 'ctrl-x': 'split',
|
||||
\ 'ctrl-v': 'vsplit' }
|
||||
|
||||
" An action can be a reference to a function that processes selected lines
|
||||
function! s:build_quickfix_list(lines)
|
||||
call setqflist(map(copy(a:lines), '{ "filename": v:val }'))
|
||||
copen
|
||||
cc
|
||||
endfunction
|
||||
|
||||
let g:fzf_action = {
|
||||
\ 'ctrl-q': function('s:build_quickfix_list'),
|
||||
\ 'ctrl-t': 'tab split',
|
||||
\ 'ctrl-x': 'split',
|
||||
\ 'ctrl-v': 'vsplit' }
|
||||
|
||||
" Default fzf layout
|
||||
" - down / up / left / right
|
||||
let g:fzf_layout = { 'down': '~40%' }
|
||||
|
||||
" You can set up fzf window using a Vim command (Neovim or latest Vim 8 required)
|
||||
let g:fzf_layout = { 'window': 'enew' }
|
||||
let g:fzf_layout = { 'window': '-tabnew' }
|
||||
let g:fzf_layout = { 'window': '10split enew' }
|
||||
|
||||
" Customize fzf colors to match your color scheme
|
||||
let g:fzf_colors =
|
||||
\ { 'fg': ['fg', 'Normal'],
|
||||
\ 'bg': ['bg', 'Normal'],
|
||||
\ 'hl': ['fg', 'Comment'],
|
||||
\ 'fg+': ['fg', 'CursorLine', 'CursorColumn', 'Normal'],
|
||||
\ 'bg+': ['bg', 'CursorLine', 'CursorColumn'],
|
||||
\ 'hl+': ['fg', 'Statement'],
|
||||
\ 'info': ['fg', 'PreProc'],
|
||||
\ 'border': ['fg', 'Ignore'],
|
||||
\ 'prompt': ['fg', 'Conditional'],
|
||||
\ 'pointer': ['fg', 'Exception'],
|
||||
\ 'marker': ['fg', 'Keyword'],
|
||||
\ 'spinner': ['fg', 'Label'],
|
||||
\ 'header': ['fg', 'Comment'] }
|
||||
|
||||
" Enable per-command history.
|
||||
" CTRL-N and CTRL-P will be automatically bound to next-history and
|
||||
" previous-history instead of down and up. If you don't like the change,
|
||||
" explicitly bind the keys to down and up in your $FZF_DEFAULT_OPTS.
|
||||
let g:fzf_history_dir = '~/.local/share/fzf-history'
|
||||
```
|
||||
|
||||
`fzf#run`
|
||||
---------
|
||||
|
||||
For more advanced uses, you can use `fzf#run([options])` function with the
|
||||
following options.
|
||||
|
||||
| Option name | Type | Description |
|
||||
| -------------------------- | ------------- | ---------------------------------------------------------------- |
|
||||
| `source` | string | External command to generate input to fzf (e.g. `find .`) |
|
||||
| `source` | list | Vim list as input to fzf |
|
||||
| `sink` | string | Vim command to handle the selected item (e.g. `e`, `tabe`) |
|
||||
| `sink` | funcref | Reference to function to process each selected item |
|
||||
| `sink*` | funcref | Similar to `sink`, but takes the list of output lines at once |
|
||||
| `options` | string/list | Options to fzf |
|
||||
| `dir` | string | Working directory |
|
||||
| `up`/`down`/`left`/`right` | number/string | Use tmux pane with the given size (e.g. `20`, `50%`) |
|
||||
| `window` (Vim 8 / Neovim) | string | Command to open fzf window (e.g. `vertical aboveleft 30new`) |
|
||||
| `launcher` | string | External terminal emulator to start fzf with (GVim only) |
|
||||
| `launcher` | funcref | Function for generating `launcher` string (GVim only) |
|
||||
|
||||
`options` entry can be either a string or a list. For simple cases, string
|
||||
should suffice, but prefer to use list type if you're concerned about escaping
|
||||
issues on different platforms.
|
||||
|
||||
```vim
|
||||
call fzf#run({'options': '--reverse --prompt "C:\\Program Files\\"'})
|
||||
call fzf#run({'options': ['--reverse', '--prompt', 'C:\Program Files\']})
|
||||
```
|
||||
|
||||
`fzf#wrap`
|
||||
----------
|
||||
|
||||
`fzf#wrap([name string,] [opts dict,] [fullscreen boolean])` is a helper
|
||||
function that decorates the options dictionary so that it understands
|
||||
`g:fzf_layout`, `g:fzf_action`, `g:fzf_colors`, and `g:fzf_history_dir` like
|
||||
`:FZF`.
|
||||
|
||||
```vim
|
||||
command! -bang MyStuff
|
||||
\ call fzf#run(fzf#wrap('my-stuff', {'dir': '~/my-stuff'}, <bang>0))
|
||||
```
|
||||
|
||||
fzf inside terminal buffer
|
||||
--------------------------
|
||||
|
||||
The latest versions of Vim and Neovim include builtin terminal emulator
|
||||
(`:terminal`) and fzf will start in a terminal buffer in the following cases:
|
||||
|
||||
- On Neovim
|
||||
- On GVim
|
||||
- On Terminal Vim with the non-default layout
|
||||
- `call fzf#run({'left': '30%'})` or `let g:fzf_layout = {'left': '30%'}`
|
||||
|
||||
### Hide statusline
|
||||
|
||||
When fzf starts in a terminal buffer, you may want to hide the statusline of
|
||||
the containing buffer.
|
||||
|
||||
```vim
|
||||
autocmd! FileType fzf
|
||||
autocmd FileType fzf set laststatus=0 noshowmode noruler
|
||||
\| autocmd BufLeave <buffer> set laststatus=2 showmode ruler
|
||||
```
|
||||
|
||||
GVim
|
||||
----
|
||||
|
||||
With the latest version of GVim, fzf will start inside the builtin terminal
|
||||
emulator of Vim. Please note that this terminal feature of Vim is still young
|
||||
and unstable and you may run into some issues.
|
||||
|
||||
If you have an older version of GVim, you need an external terminal emulator
|
||||
to start fzf with. `xterm` command is used by default, but you can customize
|
||||
it with `g:fzf_launcher`.
|
||||
|
||||
```vim
|
||||
" This is the default. %s is replaced with fzf command
|
||||
let g:fzf_launcher = 'xterm -e bash -ic %s'
|
||||
|
||||
" Use urxvt instead
|
||||
let g:fzf_launcher = 'urxvt -geometry 120x30 -e sh -c %s'
|
||||
```
|
||||
|
||||
If you're running MacVim on OSX, I recommend you to use iTerm2 as the
|
||||
launcher. Refer to the [this wiki page][macvim-iterm2] to see how to set up.

fzf requires Ruby (>= 1.8.5).
|
||||
|
||||
Installation
|
||||
------------
|
||||
|
||||
fzf project consists of the following components:
|
||||
|
||||
- `fzf` executable
|
||||
- `fzf-tmux` script for launching fzf in a tmux pane
|
||||
- Shell extensions
|
||||
- Key bindings (`CTRL-T`, `CTRL-R`, and `ALT-C`) (bash, zsh, fish)
|
||||
- Fuzzy auto-completion (bash, zsh)
|
||||
- Vim/Neovim plugin
|
||||
|
||||
You can [download fzf executable][bin] alone if you don't need the extra
|
||||
stuff.
|
||||
|
||||
[bin]: https://github.com/junegunn/fzf-bin/releases
|
||||
|
||||
### Using Homebrew or Linuxbrew
|
||||
|
||||
You can use [Homebrew](http://brew.sh/) or [Linuxbrew](http://linuxbrew.sh/)
|
||||
to install fzf.
|
||||
|
||||
```sh
|
||||
brew install fzf
|
||||
|
||||
# To install useful key bindings and fuzzy completion:
|
||||
$(brew --prefix)/opt/fzf/install
|
||||
```
|
||||
|
||||
### Using git
|
||||
|
||||
Alternatively, you can "git clone" this repository to any directory and run
|
||||
Clone this repository and run
|
||||
[install](https://github.com/junegunn/fzf/blob/master/install) script.
|
||||
|
||||
```sh
|
||||
git clone --depth 1 https://github.com/junegunn/fzf.git ~/.fzf
|
||||
git clone https://github.com/junegunn/fzf.git ~/.fzf
|
||||
~/.fzf/install
|
||||
```
|
||||
|
||||
### As Vim plugin
|
||||
The script will setup:
|
||||
|
||||
Once you have fzf installed, you can enable it inside Vim simply by adding the
|
||||
directory to `&runtimepath` as follows:
|
||||
- `fzf` executable
|
||||
- Key bindings (`CTRL-T`, `CTRL-R`, and `ALT-C`) for bash and zsh
|
||||
- Fuzzy auto-completion for bash
|
||||
|
||||
If you don't use bash or zsh, you have to manually place fzf executable in a
|
||||
directory included in `$PATH`. Key bindings are not yet supported.
|
||||
|
||||
### Install as Vim plugin
|
||||
|
||||
Once you have cloned the repository, add the following line to your .vimrc.
|
||||
|
||||
```vim
|
||||
" If installed using Homebrew
|
||||
set rtp+=/usr/local/opt/fzf
|
||||
|
||||
" If installed using git
|
||||
set rtp+=~/.fzf
|
||||
```
|
||||
|
||||
If you use [vim-plug](https://github.com/junegunn/vim-plug), the same can be
|
||||
written as:
|
||||
|
||||
```vim
|
||||
" If installed using Homebrew
|
||||
Plug '/usr/local/opt/fzf'
|
||||
|
||||
" If installed using git
|
||||
Plug '~/.fzf'
|
||||
```
|
||||
|
||||
But instead of separately installing fzf on your system (using Homebrew or
|
||||
"git clone") and enabling it on Vim (adding it to `&runtimepath`), you can use
|
||||
vim-plug to do both.
|
||||
|
||||
```vim
|
||||
" PlugInstall and PlugUpdate will clone fzf in ~/.fzf and run install script
|
||||
Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' }
|
||||
" Both options are optional. You don't have to install fzf in ~/.fzf
|
||||
" and you don't have to run install script if you use fzf only in Vim.
|
||||
```
|
||||
|
||||
### Fedora
|
||||
|
||||
fzf is available in Fedora 26 and above, and can be installed using the usual
|
||||
method:
|
||||
|
||||
```sh
|
||||
sudo dnf install fzf
|
||||
```
|
||||
|
||||
Shell completion and plugins for vim or neovim are enabled by default. Shell
|
||||
key bindings are installed but not enabled by default. See Fedora's package
|
||||
documentation for more information.
|
||||
|
||||
|
||||
### Windows
|
||||
|
||||
Pre-built binaries for Windows can be downloaded [here][bin]. fzf is also
|
||||
available as a [Chocolatey package][choco].
|
||||
|
||||
[choco]: https://chocolatey.org/packages/fzf
|
||||
|
||||
```sh
|
||||
choco install fzf
|
||||
```
|
||||
|
||||
However, other components of the project may not work on Windows. Known issues
|
||||
and limitations can be found on [the wiki page][windows-wiki]. You might want
|
||||
to consider installing fzf on [Windows Subsystem for Linux][wsl] where
|
||||
everything runs flawlessly.
|
||||
|
||||

|
||||
|
||||
Upgrading fzf
|
||||
-------------
|
||||
|
||||
fzf is being actively developed and you might want to upgrade it once in a
|
||||
while. Please follow the instruction below depending on the installation
|
||||
method used.
|
||||
|
||||
- git: `cd ~/.fzf && git pull && ./install`
|
||||
- brew: `brew update; brew reinstall fzf`
|
||||
- chocolatey: `choco upgrade fzf`
|
||||
- vim-plug: `:PlugUpdate fzf`
|
||||
|
||||
Building fzf
|
||||
------------
|
||||
|
||||
See [BUILD.md](BUILD.md).
|
||||
Or you may use any Vim plugin manager, such as
|
||||
[vim-plug](https://github.com/junegunn/vim-plug).
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
fzf will launch interactive finder, read the list from STDIN, and write the
|
||||
```
|
||||
usage: fzf [options]
|
||||
|
||||
Search
|
||||
-x, --extended Extended-search mode
|
||||
-e, --extended-exact Extended-search mode (exact match)
|
||||
-i Case-insensitive match (default: smart-case match)
|
||||
+i Case-sensitive match
|
||||
-n, --nth=[-]N[,..] Comma-separated list of field indexes for limiting
|
||||
search scope (positive or negative integers)
|
||||
-d, --delimiter=STR Field delimiter regex for --nth (default: AWK-style)
|
||||
|
||||
Search result
|
||||
-s, --sort=MAX Maximum number of matched items to sort (default: 1000)
|
||||
+s, --no-sort Do not sort the result. Keep the sequence unchanged.
|
||||
|
||||
Interface
|
||||
-m, --multi Enable multi-select with tab/shift-tab
|
||||
--no-mouse Disable mouse
|
||||
+c, --no-color Disable colors
|
||||
+2, --no-256 Disable 256-color
|
||||
--black Use black background
|
||||
|
||||
Scripting
|
||||
-q, --query=STR Start the finder with the given query
|
||||
-1, --select-1 Automatically select the only match
|
||||
-0, --exit-0 Exit immediately when there's no match
|
||||
-f, --filter=STR Filter mode. Do not start interactive finder.
|
||||
|
||||
Environment variables
|
||||
FZF_DEFAULT_COMMAND Default command to use when input is tty
|
||||
FZF_DEFAULT_OPTS Defaults options. (e.g. "-x -m --sort 10000")
|
||||
```
|
||||
|
||||
fzf will launch curses-based finder, read the list from STDIN, and write the
|
||||
selected item to STDOUT.
|
||||
|
||||
```sh
|
||||
@ -199,140 +96,140 @@ files excluding hidden ones. (You can override the default command with
|
||||
vim $(fzf)
|
||||
```
|
||||
|
||||
#### Using the finder
|
||||
|
||||
- `CTRL-J` / `CTRL-K` (or `CTRL-N` / `CTRL-P`) to move cursor up and down
|
||||
- `Enter` key to select the item, `CTRL-C` / `CTRL-G` / `ESC` to exit
|
||||
- On multi-select mode (`-m`), `TAB` and `Shift-TAB` to mark multiple items
|
||||
- Emacs style key bindings
|
||||
- Mouse: scroll, click, double-click; shift-click and shift-scroll on
|
||||
multi-select mode
|
||||
|
||||
#### Layout
|
||||
|
||||
fzf by default starts in fullscreen mode, but you can make it start below the
|
||||
cursor with `--height` option.
|
||||
If you want to preserve the exact sequence of the input, provide `--no-sort` (or
|
||||
`+s`) option.
|
||||
|
||||
```sh
|
||||
vim $(fzf --height 40%)
|
||||
history | fzf +s
|
||||
```
|
||||
|
||||
Also check out `--reverse` option if you prefer "top-down" layout instead of
|
||||
the default "bottom-up" layout.
|
||||
### Keys
|
||||
|
||||
Use CTRL-J and CTRL-K (or CTRL-N and CTRL-P) to change the selection, press
|
||||
enter key to select the item. CTRL-C, CTRL-G, or ESC will terminate the finder.
|
||||
|
||||
The following readline key bindings should also work as expected.
|
||||
|
||||
- CTRL-A / CTRL-E
|
||||
- CTRL-B / CTRL-F
|
||||
- CTRL-W / CTRL-U / CTRL-Y
|
||||
- ALT-B / ALT-F
|
||||
|
||||
If you enable multi-select mode with `-m` option, you can select multiple items
|
||||
with TAB or Shift-TAB key.
|
||||
|
||||
You can also use mouse. Double-click on an item to select it or shift-click (or
|
||||
ctrl-click) to select multiple items. Use mouse wheel to move the cursor up and
|
||||
down.
|
||||
|
||||
### Extended-search mode
|
||||
|
||||
With `-x` or `--extended` option, fzf will start in "extended-search mode".
|
||||
|
||||
In this mode, you can specify multiple patterns delimited by spaces,
|
||||
such as: `^music .mp3$ sbtrkt !rmx`
|
||||
|
||||
| Token | Description | Match type |
|
||||
| -------- | -------------------------------- | -------------------- |
|
||||
| `^music` | Items that start with `music` | prefix-exact-match |
|
||||
| `.mp3$` | Items that end with `.mp3` | suffix-exact-match |
|
||||
| `sbtrkt` | Items that match `sbtrkt` | fuzzy-match |
|
||||
| `!rmx` | Items that do not match `rmx` | inverse-fuzzy-match |
|
||||
| `'wild` | Items that include `wild` | exact-match (quoted) |
|
||||
| `!'fire` | Items that do not include `fire` | inverse-exact-match |
|
||||
|
||||
If you don't need fuzzy matching and do not wish to "quote" every word, start
|
||||
fzf with `-e` or `--extended-exact` option.
|
||||
|
||||
Useful examples
|
||||
---------------
|
||||
|
||||
```sh
|
||||
vim $(fzf --height 40% --reverse)
|
||||
```
|
||||
# fe [FUZZY PATTERN] - Open the selected file with the default editor
|
||||
# - Bypass fuzzy finder if there's only one match (--select-1)
|
||||
# - Exit if there's no match (--exit-0)
|
||||
fe() {
|
||||
local file
|
||||
file=$(fzf --query="$1" --select-1 --exit-0)
|
||||
[ -n "$file" ] && ${EDITOR:-vim} "$file"
|
||||
}
|
||||
|
||||
You can add these options to `$FZF_DEFAULT_OPTS` so that they're applied by
|
||||
default. For example,
|
||||
# fd - cd to selected directory
|
||||
fd() {
|
||||
local dir
|
||||
dir=$(find ${1:-*} -path '*/\.*' -prune \
|
||||
-o -type d -print 2> /dev/null | fzf +m) &&
|
||||
cd "$dir"
|
||||
}
|
||||
|
||||
```sh
|
||||
export FZF_DEFAULT_OPTS='--height 40% --reverse --border'
|
||||
```
|
||||
# fda - including hidden directories
|
||||
fda() {
|
||||
local dir
|
||||
dir=$(find ${1:-.} -type d 2> /dev/null | fzf +m) && cd "$dir"
|
||||
}
|
||||
|
||||
#### Search syntax
|
||||
# fh - repeat history
|
||||
fh() {
|
||||
eval $(([ -n "$ZSH_NAME" ] && fc -l 1 || history) | fzf +s | sed 's/ *[0-9]* *//')
|
||||
}
|
||||
|
||||
Unless otherwise specified, fzf starts in "extended-search mode" where you can
|
||||
type in multiple search terms delimited by spaces. e.g. `^music .mp3$ sbtrkt
|
||||
!fire`
|
||||
# fkill - kill process
|
||||
fkill() {
|
||||
ps -ef | sed 1d | fzf -m | awk '{print $2}' | xargs kill -${1:-9}
|
||||
}
|
||||
|
||||
| Token | Match type | Description |
|
||||
| -------- | -------------------------- | --------------------------------- |
|
||||
| `sbtrkt` | fuzzy-match | Items that match `sbtrkt` |
|
||||
| `^music` | prefix-exact-match | Items that start with `music` |
|
||||
| `.mp3$` | suffix-exact-match | Items that end with `.mp3` |
|
||||
| `'wild` | exact-match (quoted) | Items that include `wild` |
|
||||
| `!fire` | inverse-exact-match | Items that do not include `fire` |
|
||||
| `!.mp3$` | inverse-suffix-exact-match | Items that do not end with `.mp3` |
|
||||
# fbr - checkout git branch
|
||||
fbr() {
|
||||
local branches branch
|
||||
branches=$(git branch) &&
|
||||
branch=$(echo "$branches" | fzf +s +m) &&
|
||||
git checkout $(echo "$branch" | sed "s/.* //")
|
||||
}
|
||||
|
||||
If you don't prefer fuzzy matching and do not wish to "quote" every word,
|
||||
start fzf with `-e` or `--exact` option. Note that when `--exact` is set,
|
||||
`'`-prefix "unquotes" the term.
|
||||
# fco - checkout git commit
|
||||
fco() {
|
||||
local commits commit
|
||||
commits=$(git log --pretty=oneline --abbrev-commit --reverse) &&
|
||||
commit=$(echo "$commits" | fzf +s +m -e) &&
|
||||
git checkout $(echo "$commit" | sed "s/ .*//")
|
||||
}
|
||||
|
||||
A single bar character term acts as an OR operator. For example, the following
|
||||
query matches entries that start with `core` and end with either `go`, `rb`,
|
||||
or `py`.
|
||||
|
||||
```
|
||||
^core go$ | rb$ | py$
|
||||
```
|
||||
|
||||
#### Environment variables
|
||||
|
||||
- `FZF_DEFAULT_COMMAND`
|
||||
- Default command to use when input is tty
|
||||
- e.g. `export FZF_DEFAULT_COMMAND='fd --type f'`
|
||||
- `FZF_DEFAULT_OPTS`
|
||||
- Default options
|
||||
- e.g. `export FZF_DEFAULT_OPTS="--reverse --inline-info"`
|
||||
|
||||
#### Options
|
||||
|
||||
See the man page (`man fzf`) for the full list of options.
|
||||
|
||||
Examples
|
||||
--------
|
||||
|
||||
Many useful examples can be found on [the wiki
|
||||
page](https://github.com/junegunn/fzf/wiki/examples). Feel free to add your
|
||||
own as well.
|
||||
|
||||
`fzf-tmux` script
|
||||
-----------------
|
||||
|
||||
[fzf-tmux](bin/fzf-tmux) is a bash script that opens fzf in a tmux pane.
|
||||
|
||||
```sh
|
||||
# usage: fzf-tmux [-u|-d [HEIGHT[%]]] [-l|-r [WIDTH[%]]] [--] [FZF OPTIONS]
|
||||
# (-[udlr]: up/down/left/right)
|
||||
|
||||
# select git branches in horizontal split below (15 lines)
|
||||
git branch | fzf-tmux -d 15
|
||||
|
||||
# select multiple words in vertical split on the left (20% of screen width)
|
||||
cat /usr/share/dict/words | fzf-tmux -l 20% --multi --reverse
|
||||
```
|
||||
|
||||
It will still work even when you're not on tmux, silently ignoring `-[udlr]`
|
||||
options, so you can invariably use `fzf-tmux` in your scripts.
|
||||
|
||||
Alternatively, you can use `--height HEIGHT[%]` option not to start fzf in
|
||||
fullscreen mode.
|
||||
|
||||
```sh
|
||||
fzf --height 40%
|
||||
# ftags - search ctags
|
||||
ftags() {
|
||||
local line
|
||||
[ -e tags ] &&
|
||||
line=$(
|
||||
awk 'BEGIN { FS="\t" } !/^!/ {print toupper($4)"\t"$1"\t"$2"\t"$3}' tags |
|
||||
cut -c1-80 | fzf --nth=1,2
|
||||
) && $EDITOR $(cut -f3 <<< "$line") -c "set nocst" \
|
||||
-c "silent tag $(cut -f2 <<< "$line")"
|
||||
}
|
||||
```
|
||||
|
||||
Key bindings for command line
|
||||
-----------------------------
|
||||
|
||||
The install script will setup the following key bindings for bash, zsh, and
|
||||
fish.
|
||||
The install script will setup the following key bindings.
|
||||
|
||||
- `CTRL-T` - Paste the selected files and directories onto the command line
|
||||
- Set `FZF_CTRL_T_COMMAND` to override the default command
|
||||
- Set `FZF_CTRL_T_OPTS` to pass additional options
|
||||
- `CTRL-R` - Paste the selected command from history onto the command line
|
||||
- If you want to see the commands in chronological order, press `CTRL-R`
|
||||
again which toggles sorting by relevance
|
||||
- Set `FZF_CTRL_R_OPTS` to pass additional options
|
||||
### bash/zsh
|
||||
|
||||
- `CTRL-T` - Paste the selected file path(s) into the command line
|
||||
- `CTRL-R` - Paste the selected command from history into the command line
|
||||
- `ALT-C` - cd into the selected directory
|
||||
- Set `FZF_ALT_C_COMMAND` to override the default command
|
||||
- Set `FZF_ALT_C_OPTS` to pass additional options
|
||||
|
||||
If you're on a tmux session, you can start fzf in a split pane by setting
|
||||
`FZF_TMUX` to 1, and change the height of the pane with `FZF_TMUX_HEIGHT`
|
||||
(e.g. `20`, `50%`).
|
||||
If you're on a tmux session, `CTRL-T` will launch fzf in a new split-window. You
|
||||
may disable this tmux integration by setting `FZF_TMUX` to 0, or change the
|
||||
height of the window with `FZF_TMUX_HEIGHT` (e.g. `20`, `50%`).
|
||||
|
||||
If you use vi mode on bash, you need to add `set -o vi` *before* `source
|
||||
~/.fzf.bash` in your .bashrc, so that it correctly sets up key bindings for vi
|
||||
mode.
|
||||
The source code can be found in `~/.fzf.bash` and in `~/.fzf.zsh`.
|
||||

||||

Usage as Vim plugin
|
||||
-------------------
|
||||
|
||||
(fzf is a command-line utility, naturally it is only accessible in terminal Vim)
|
||||
|
||||
### `:FZF[!]`
|
||||
|
||||
If you have set up fzf for Vim, `:FZF` command will be added.
|
||||
|
||||
```vim
|
||||
" Look for files under current directory
|
||||
:FZF
|
||||
|
||||
" Look for files under your home directory
|
||||
:FZF ~
|
||||
|
||||
" With options
|
||||
:FZF --no-sort -m /tmp
|
||||
```
|
||||
|
||||
Vim plugin
|
||||
----------
|
||||
Note that the environment variables `FZF_DEFAULT_COMMAND` and `FZF_DEFAULT_OPTS`
|
||||
also apply here.
|
||||
|
||||
See [README-VIM.md](README-VIM.md).
|
||||
If you're on a tmux session, `:FZF` will launch fzf in a new split-window whose
|
||||
height can be adjusted with `g:fzf_tmux_height` (default: '40%'). However, the
|
||||
bang version (`:FZF!`) will always start in fullscreen.
|
||||
|
||||
Advanced topics
|
||||
---------------
|
||||
### `fzf#run([options])`
|
||||
|
||||
### Performance
|
||||
For more advanced uses, you can call `fzf#run()` function which returns the list
|
||||
of the selected items.
|
||||
|
||||
fzf is fast, and is [getting even faster][perf]. Performance should not be
|
||||
a problem in most use cases. However, you might want to be aware of the
|
||||
options that affect the performance.
|
||||
`fzf#run()` may take an options-dictionary:
|
||||
|
||||
- `--ansi` tells fzf to extract and parse ANSI color codes in the input and it
|
||||
makes the initial scanning slower. So it's not recommended that you add it
|
||||
to your `$FZF_DEFAULT_OPTS`.
|
||||
- `--nth` makes fzf slower as fzf has to tokenize each line.
|
||||
- `--with-nth` makes fzf slower as fzf has to tokenize and reassemble each
|
||||
line.
|
||||
- If you absolutely need better performance, you can consider using
|
||||
`--algo=v1` (the default being `v2`) to make fzf use faster greedy
|
||||
algorithm. However, this algorithm is not guaranteed to find the optimal
|
||||
ordering of the matches and is not recommended.
|
||||
| Option name | Type | Description |
|
||||
| ------------- | ------------- | ------------------------------------------------------------------ |
|
||||
| `source` | string | External command to generate input to fzf (e.g. `find .`) |
|
||||
| `source` | list | Vim list as input to fzf |
|
||||
| `sink` | string | Vim command to handle the selected item (e.g. `e`, `tabe`) |
|
||||
| `sink` | funcref | Reference to function to process each selected item |
|
||||
| `options` | string | Options to fzf |
|
||||
| `dir` | string | Working directory |
|
||||
| `tmux_width` | number/string | Use tmux vertical split with the given height (e.g. `20`, `50%`) |
|
||||
| `tmux_height` | number/string | Use tmux horizontal split with the given height (e.g. `20`, `50%`) |
|
||||
|
||||
[perf]: https://junegunn.kr/images/fzf-0.17.0.png
|
||||
#### Examples
|
||||
|
||||
### Executing external programs
|
||||
If `sink` option is not given, `fzf#run` will simply return the list.
|
||||
|
||||
You can set up key bindings for starting external processes without leaving
|
||||
fzf (`execute`, `execute-silent`).
|
||||
|
||||
```bash
|
||||
# Press F1 to open the file with less without leaving fzf
|
||||
# Press CTRL-Y to copy the line to clipboard and aborts fzf (requires pbcopy)
|
||||
fzf --bind 'f1:execute(less -f {}),ctrl-y:execute-silent(echo {} | pbcopy)+abort'
|
||||
```vim
|
||||
let items = fzf#run({ 'options': '-m +c', 'dir': '~', 'source': 'ls' })
|
||||
```
|
||||
|
||||
See *KEY BINDINGS* section of the man page for details.
|
||||
But if `sink` is given as a string, the command will be executed for each
|
||||
selected item.
|
||||
|
||||
### Preview window
|
||||
|
||||
When `--preview` option is set, fzf automatically starts external process with
|
||||
the current line as the argument and shows the result in the split window.
|
||||
|
||||
```bash
|
||||
# {} is replaced to the single-quoted string of the focused line
|
||||
fzf --preview 'cat {}'
|
||||
```vim
|
||||
" Each selected item will be opened in a new tab
|
||||
let items = fzf#run({ 'sink': 'tabe', 'options': '-m +c', 'dir': '~', 'source': 'ls' })
|
||||
```
|
||||
|
||||
Since preview window is updated only after the process is complete, it's
|
||||
important that the command finishes quickly.
|
||||
We can also use a Vim list as the source as follows:
|
||||
|
||||
```bash
|
||||
# Use head instead of cat so that the command doesn't take too long to finish
|
||||
fzf --preview 'head -100 {}'
|
||||
```vim
|
||||
" Choose a color scheme with fzf
|
||||
nnoremap <silent> <Leader>C :call fzf#run({
|
||||
\ 'source':
|
||||
\ map(split(globpath(&rtp, "colors/*.vim"), "\n"),
|
||||
\ "substitute(fnamemodify(v:val, ':t'), '\\..\\{-}$', '', '')"),
|
||||
\ 'sink': 'colo',
|
||||
\ 'options': '+m',
|
||||
\ 'tmux_width': 20
|
||||
\ })<CR>
|
||||
```
|
||||
|
||||
Preview window supports ANSI colors, so you can use programs that
|
||||
syntax-highlights the content of a file.
|
||||
`sink` option can be a function reference. The following example creates a
|
||||
handy mapping that selects an open buffer.
|
||||
|
||||

|
||||
- CodeRay: http://coderay.rubychan.de/
|
||||
- Rouge: https://github.com/jneen/rouge
|
||||
```vim
|
||||
" List of buffers
|
||||
function! g:buflist()
|
||||
redir => ls
|
||||
silent ls
|
||||
redir END
|
||||
return split(ls, '\n')
|
||||
endfunction
|
||||
|
||||
```bash
|
||||
# Try highlight, coderay, rougify in turn, then fall back to cat
|
||||
fzf --preview '[[ $(file --mime {}) =~ binary ]] &&
|
||||
echo {} is a binary file ||
|
||||
(highlight -O ansi -l {} ||
|
||||
coderay {} ||
|
||||
rougify {} ||
|
||||
cat {}) 2> /dev/null | head -500'
|
||||
function! g:bufopen(e)
|
||||
execute 'buffer '. matchstr(a:e, '^[ 0-9]*')
|
||||
endfunction
|
||||
|
||||
nnoremap <silent> <Leader><Enter> :call fzf#run({
|
||||
\ 'source': reverse(g:buflist()),
|
||||
\ 'sink': function('g:bufopen'),
|
||||
\ 'options': '+m',
|
||||
\ 'tmux_height': '40%'
|
||||
\ })<CR>
|
||||
```
|
||||
|
||||
You can customize the size and position of the preview window using
|
||||
`--preview-window` option. For example,
|
||||
|
||||
```bash
|
||||
fzf --height 40% --reverse --preview 'file {}' --preview-window down:1
|
||||
```

Tips
|
||||
----
|
||||
|
||||
#### Respecting `.gitignore`
|
||||
### Rendering issues
|
||||
|
||||
You can use [fd](https://github.com/sharkdp/fd),
|
||||
[ripgrep](https://github.com/BurntSushi/ripgrep), or [the silver
|
||||
searcher](https://github.com/ggreer/the_silver_searcher) instead of the
|
||||
default find command to traverse the file system while respecting
|
||||
`.gitignore`.
|
||||
If you have any rendering issues, check the followings:
|
||||
|
||||
1. Make sure `$TERM` is correctly set. fzf will use 256-color only if it
|
||||
contains `256` (e.g. `xterm-256color`)
|
||||
2. If you're on screen or tmux, `$TERM` should be either `screen` or
|
||||
`screen-256color`
|
||||
3. Some terminal emulators (e.g. mintty) have problem displaying default
|
||||
background color and make some text unable to read. In that case, try `--black`
|
||||
option. And if it solves your problem, I recommend including it in
|
||||
`FZF_DEFAULT_OPTS` for further convenience.
|
||||
4. If you still have problem, try `--no-256` option or even `--no-color`.
|
||||
5. Ruby 1.9 or above is required for correctly displaying unicode characters.
|
||||
|
||||
### Ranking algorithm
|
||||
|
||||
fzf sorts the result first by the length of the matched substring, then by the
|
||||
length of the whole string. However it only does so when the number of matches
|
||||
is less than the limit which is by default 1000, in order to avoid the cost of
|
||||
sorting a large list and limit the response time of the query.
|
||||
|
||||
This limit can be adjusted with `-s` option, or with the environment variable
|
||||
`FZF_DEFAULT_OPTS`.
|
||||
|
||||
```sh
|
||||
# Feed the output of fd into fzf
|
||||
fd --type f | fzf
|
||||
export FZF_DEFAULT_OPTS="--sort 20000"
|
||||
```
|
||||
|
||||
# Setting fd as the default source for fzf
|
||||
export FZF_DEFAULT_COMMAND='fd --type f'
|
||||
### Respecting `.gitignore`, `.hgignore`, and `svn:ignore`
|
||||
|
||||
# Now fzf (w/o pipe) will use fd instead of find
|
||||
[ag](https://github.com/ggreer/the_silver_searcher) or
|
||||
[pt](https://github.com/monochromegane/the_platinum_searcher) will do the
|
||||
filtering:
|
||||
|
||||
```sh
|
||||
# Feed the output of ag into fzf
|
||||
ag -l -g "" | fzf
|
||||
|
||||
# Setting ag as the default source for fzf
|
||||
export FZF_DEFAULT_COMMAND='ag -l -g ""'
|
||||
|
||||
# Now fzf (w/o pipe) will use ag instead of find
|
||||
fzf
|
||||
|
||||
# To apply the command to CTRL-T as well
|
||||
export FZF_CTRL_T_COMMAND="$FZF_DEFAULT_COMMAND"
|
||||
```
|
||||
|
||||
If you want the command to follow symbolic links, and don't want it to exclude
|
||||
hidden files, use the following command:
|
||||
### Windows
|
||||
|
||||
```sh
|
||||
export FZF_DEFAULT_COMMAND='fd --type f --hidden --follow --exclude .git'
|
||||
```
|
||||
fzf works on [Cygwin](http://www.cygwin.com/) and
|
||||
[MSYS2](http://sourceforge.net/projects/msys2/). You may need to use `--black`
|
||||
option on MSYS2 to avoid rendering issues.
|
||||
|
||||
#### `git ls-tree` for fast traversal
|
||||
|
||||
If you're running fzf in a large git repository, `git ls-tree` can boost up the
|
||||
speed of the traversal.
|
||||

|
||||
-------
|
||||
|
||||
```sh
|
||||
export FZF_DEFAULT_COMMAND='
|
||||
(git ls-tree -r --name-only HEAD ||
|
||||
find . -path "*/\.*" -prune -o -type f -print -o -type l -print |
|
||||
sed s/^..//) 2> /dev/null'

#### Fish shell
|
||||
Author
|
||||
------
|
||||
|
||||
Fish shell before version 2.6.0 [doesn't allow](https://github.com/fish-shell/fish-shell/issues/1362)
|
||||
reading from STDIN in command substitution, which means simple `vim (fzf)`
|
||||
doesn't work as expected. The workaround for fish 2.5.0 and earlier is to use
|
||||
the `read` fish command:
|
||||
Junegunn Choi
|
||||
|
||||
```sh
|
||||
fzf | read -l result; and vim $result
|
||||
```
|
||||
|
||||
or, for multiple results:
|
||||
|
||||
```sh
|
||||
fzf -m | while read -l r; set result $result $r; end; and vim $result
|
||||
```
|
||||
|
||||
The globbing system is different in fish and thus `**` completion will not work.
|
||||
However, the `CTRL-T` command will use the last token on the commandline as the
|
||||
root folder for the recursive search. For instance, hitting `CTRL-T` at the end
|
||||
of the following commandline
|
||||
|
||||
```sh
|
||||
ls /var/
|
||||
```
|
||||
|
||||
will list all files and folders under `/var/`.
|
||||
|
||||
When using a custom `FZF_CTRL_T_COMMAND`, use the unexpanded `$dir` variable to
|
||||
make use of this feature. `$dir` defaults to `.` when the last token is not a
|
||||
valid directory. Example:
|
||||
|
||||
```sh
|
||||
set -g FZF_CTRL_T_COMMAND "command find -L \$dir -type f 2> /dev/null | sed '1d; s#^\./##'"
|
||||
```

FZF VIM INTEGRATION *fzf-vim-integration*
|
||||
==============================================================================
|
||||
|
||||
This repository only enables basic integration with Vim. If you're looking for
|
||||
more, check out {fzf.vim}{1} project.
|
||||
|
||||
(Note: To use fzf in GVim, an external terminal emulator is required.)

:FZF[!]
|
||||
==============================================================================
|
||||
|
||||
*:FZF*
|
||||
|
||||
If you have set up fzf for Vim, `:FZF` command will be added.
|
||||
>
|
||||
" Look for files under current directory
|
||||
:FZF
|
||||
|

<
|
||||
Similarly to {ctrlp.vim}{2}, use enter key, CTRL-T, CTRL-X or CTRL-V to open
|
||||
selected files in the current window, in new tabs, in horizontal splits, or in
|
||||
vertical splits respectively.
|
||||
|
||||
Note that the environment variables `FZF_DEFAULT_COMMAND` and
|
||||
`FZF_DEFAULT_OPTS` also apply here.

FZF#RUN *fzf#run*
|
||||
==============================================================================
|
||||
|
||||
For more advanced uses, you can use `fzf#run([options])` function with the
|
||||
following options.
|
||||
|
||||
---------------------------+---------------+--------------------------------------------------------------
|
||||
Option name | Type | Description ~
|
||||
---------------------------+---------------+--------------------------------------------------------------
|
||||
`source` | string | External command to generate input to fzf (e.g. `find .` )
|
||||
`source` | list | Vim list as input to fzf
|
||||
`sink` | string | Vim command to handle the selected item (e.g. `e` , `tabe` )
|
||||
`sink` | funcref | Reference to function to process each selected item
|
||||
`sink*` | funcref | Similar to `sink` , but takes the list of output lines at once
|
||||
`options` | string/list | Options to fzf
|
||||
`dir` | string | Working directory
|
||||
`up` / `down` / `left` / `right` | number/string | Use tmux pane with the given size (e.g. `20` , `50%` )
|
||||
`window` (Vim 8 / Neovim) | string | Command to open fzf window (e.g. `vertical aboveleft 30new` )
|
||||
`launcher` | string | External terminal emulator to start fzf with (GVim only)
|
||||
`launcher` | funcref | Function for generating `launcher` string (GVim only)
|
||||
---------------------------+---------------+--------------------------------------------------------------
|
||||
|
||||
`options` entry can be either a string or a list. For simple cases, string
|
||||
should suffice, but prefer to use list type if you're concerned about escaping
|
||||
issues on different platforms.

||||

call fzf#run({'options': '--reverse --prompt "C:\\Program Files\\"'})
|
||||
call fzf#run({'options': ['--reverse', '--prompt', 'C:\Program Files\']})
|
||||
<
|
||||
|
||||
FZF#WRAP *fzf#wrap*
|
||||
==============================================================================
|
||||
|
||||
`fzf#wrap([name string,] [opts dict,] [fullscreen boolean])` is a helper
|
||||
function that decorates the options dictionary so that it understands
|
||||
`g:fzf_layout`, `g:fzf_action`, `g:fzf_colors`, and `g:fzf_history_dir` like
|
||||
`:FZF`.
|
||||
>
|
||||
command! -bang MyStuff
|
||||
\ call fzf#run(fzf#wrap('my-stuff', {'dir': '~/my-stuff'}, <bang>0))
|
||||
<
|
||||
|
||||
FZF INSIDE TERMINAL BUFFER *fzf-inside-terminal-buffer*
|
||||
==============================================================================
|
||||
|
||||
The latest versions of Vim and Neovim include builtin terminal emulator
|
||||
(`:terminal`) and fzf will start in a terminal buffer in the following cases:
|
||||
|
||||
- On Neovim
|
||||
- On GVim
|
||||
- On Terminal Vim with the non-default layout
|
||||
- `call fzf#run({'left': '30%'})` or `let g:fzf_layout = {'left': '30%'}`
|
||||
|
||||
|
||||
< Hide statusline >___________________________________________________________~
|
||||
*fzf-hide-statusline*
|
||||
|
||||
When fzf starts in a terminal buffer, you may want to hide the statusline of
|
||||
the containing buffer.
|
||||
>
|
||||
autocmd! FileType fzf
|
||||
autocmd FileType fzf set laststatus=0 noshowmode noruler
|
||||
\| autocmd BufLeave <buffer> set laststatus=2 showmode ruler
|
||||
<
|

GVIM *fzf-gvim*
|
||||

With the latest version of GVim, fzf will start inside the builtin terminal
|
||||
emulator of Vim. Please note that this terminal feature of Vim is still young
|
||||
and unstable and you may run into some issues.
|
||||
|
||||
If you have an older version of GVim, you need an external terminal emulator
|
||||
to start fzf with. `xterm` command is used by default, but you can customize
|
||||
it with `g:fzf_launcher`.
|
||||
>
|
||||
" This is the default. %s is replaced with fzf command
|
||||
let g:fzf_launcher = 'xterm -e bash -ic %s'
|
||||
|
||||
" Use urxvt instead
|
||||
let g:fzf_launcher = 'urxvt -geometry 120x30 -e sh -c %s'
|
||||
<
|
||||
If you're running MacVim on OSX, I recommend you to use iTerm2 as the
|
||||
launcher. Refer to the {this wiki page}{3} to see how to set up.

|

|
||||
.SH DESCRIPTION
|
||||
fzf-tmux is a wrapper script for fzf that opens fzf in a tmux split pane. It is
|
||||
designed to work just like fzf except that it does not take up the whole
|
||||
screen. You can safely use fzf-tmux instead of fzf in your scripts as the extra
|
||||
options will be silently ignored if you're not on tmux.

.SH FIELD INDEX EXPRESSION
|
||||
|
||||
A field index expression can be a non-zero integer or a range expression
|
||||
([BEGIN]..[END]). \fB--nth\fR and \fB--with-nth\fR take a comma-separated list
|
||||
of field index expressions.
|
||||
|
||||
.SS Examples
|
||||
.BR 1 " The 1st field"
|
||||
.br
|
||||
.BR 2 " The 2nd field"
|
||||
.br
|
||||
.BR -1 " The last field"
|
||||
.br
|
||||
.BR -2 " The 2nd to last field"
|
||||
.br
|
||||
.BR 3..5 " From the 3rd field to the 5th field"
|
||||
.br
|
||||
.BR 2.. " From the 2nd field to the last field"
|
||||
.br
|
||||
.BR ..-3 " From the 1st field to the 3rd to the last field"
|
||||
.br
|
||||
.BR .. " All the fields"
|
||||
.br
|
||||
|
||||
.SH EXTENDED SEARCH MODE
|
||||
|
||||
Unless specified otherwise, fzf will start in "extended-search mode". In this
|
||||
mode, you can specify multiple patterns delimited by spaces, such as: \fB'wild
|
||||
^music .mp3$ sbtrkt !rmx\fR
|
||||
|
||||
You can prepend a backslash to a space (\fB\\ \fR) to match a literal space
|
||||
character.
|
||||
|
||||
.SS Exact-match (quoted)
|
||||
A term that is prefixed by a single-quote character (\fB'\fR) is interpreted as
|
||||
an "exact-match" (or "non-fuzzy") term. fzf will search for the exact
|
||||
occurrences of the string.
|
||||
|
||||
.SS Anchored-match
|
||||
A term can be prefixed by \fB^\fR, or suffixed by \fB$\fR to become an
|
||||
anchored-match term. Then fzf will search for the lines that start with or end
|
||||
with the given string. An anchored-match term is also an exact-match term.
|
||||
|
||||
.SS Negation
|
||||
If a term is prefixed by \fB!\fR, fzf will exclude the lines that satisfy the
|
||||
term from the result. In this case, fzf performs exact match by default.
|
||||
|
||||
.SS Exact-match by default
|
||||
If you don't prefer fuzzy matching and do not wish to "quote" (prefixing with
|
||||
\fB'\fR) every word, start fzf with \fB-e\fR or \fB--exact\fR option. Note that
|
||||
when \fB--exact\fR is set, \fB'\fR-prefix "unquotes" the term.
|
||||
|
||||
.SS OR operator
|
||||
A single bar character term acts as an OR operator. For example, the following
|
||||
query matches entries that start with \fBcore\fR and end with either \fBgo\fR,
|
||||
\fBrb\fR, or \fBpy\fR.
|
||||
|
||||
e.g. \fB^core go$ | rb$ | py$\fR
|
||||
|
||||
.SH KEY BINDINGS
|
||||
You can customize key bindings of fzf with \fB--bind\fR option which takes
|
||||
a comma-separated list of key binding expressions. Each key binding expression
|
||||
follows the following format: \fBKEY:ACTION\fR
|
||||
|
||||
e.g. \fBfzf --bind=ctrl-j:accept,ctrl-k:kill-line\fR
|
||||

|

|

With \fBexecute(...)\fR action, you can execute arbitrary commands without
|
||||
leaving fzf. For example, you can turn fzf into a simple file browser by
|
||||
binding \fBenter\fR key to \fBless\fR command like follows.
|
||||
|
||||
\fBfzf --bind "enter:execute(less {})"\fR
|
||||
|
||||
You can use the same placeholder expressions as in \fB--preview\fR.
|
||||
|
||||
If the command contains parentheses, fzf may fail to parse the expression. In
|
||||
that case, you can use any of the following alternative notations to avoid
|
||||
parse errors.
|
||||
|
||||
\fBexecute[...]\fR
|
||||
\fBexecute~...~\fR
|
||||
\fBexecute!...!\fR
|
||||
\fBexecute@...@\fR
|
||||
\fBexecute#...#\fR
|
||||
\fBexecute$...$\fR
|
||||
\fBexecute%...%\fR
|
||||
\fBexecute^...^\fR
|
||||
\fBexecute&...&\fR
|
||||
\fBexecute*...*\fR
|
||||
\fBexecute;...;\fR
|
||||
\fBexecute/.../\fR
|
||||
\fBexecute|...|\fR
|
||||
\fBexecute:...\fR
|
||||
.RS
|
||||
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 of key-action pairs.
|
||||
.RE
|
||||
|
||||
fzf switches to the alternate screen when executing a command. However, if the
|
||||
command is expected to complete quickly, and you are not interested in its
|
||||
output, you might want to use \fBexecute-silent\fR instead, which silently
|
||||
executes the command without the switching. Note that fzf will not be
|
||||
responsible until the command is complete. For asynchronous execution, start
|
||||
your command as a background process (i.e. appending \fB&\fR).

Algorithm
|
||||
---------
|
||||
|
||||
FuzzyMatchV1 finds the first "fuzzy" occurrence of the pattern within the given
|
||||
text in O(n) time where n is the length of the text. Once the position of the
|
||||
last character is located, it traverses backwards to see if there's a shorter
|
||||
substring that matches the pattern.
|
||||
|
||||
a_____b___abc__ To find "abc"
|
||||
*-----*-----*> 1. Forward scan
|
||||
<*** 2. Backward scan
|
||||
|
||||
The algorithm is simple and fast, but as it only sees the first occurrence,
|
||||
it is not guaranteed to find the occurrence with the highest score.
|
||||
|
||||
a_____b__c__abc
|
||||
*-----*--* ***
|
||||
|
||||
FuzzyMatchV2 implements a modified version of Smith-Waterman algorithm to find
|
||||
the optimal solution (highest score) according to the scoring criteria. Unlike
|
||||
the original algorithm, omission or mismatch of a character in the pattern is
|
||||
not allowed.
|
||||
|
||||
Performance
|
||||
-----------
|
||||
|
||||
The new V2 algorithm is slower than V1 as it examines all occurrences of the
|
||||
pattern instead of stopping immediately after finding the first one. The time
|
||||
complexity of the algorithm is O(nm) if a match is found and O(n) otherwise
|
||||
where n is the length of the item and m is the length of the pattern. Thus, the
|
||||
performance overhead may not be noticeable for a query with high selectivity.
|
||||
However, if the performance is more important than the quality of the result,
|
||||
you can still choose v1 algorithm with --algo=v1.
|
||||
|
||||
Scoring criteria
|
||||
----------------
|
||||
|
||||
- We prefer matches at special positions, such as the start of a word, or
|
||||
uppercase character in camelCase words.
|
||||
|
||||
- That is, we prefer an occurrence of the pattern with more characters
|
||||
matching at special positions, even if the total match length is longer.
|
||||
e.g. "fuzzyfinder" vs. "fuzzy-finder" on "ff"
|
||||
````````````
|
||||
- Also, if the first character in the pattern appears at one of the special
|
||||
positions, the bonus point for the position is multiplied by a constant
|
||||
as it is extremely likely that the first character in the typed pattern
|
||||
has more significance than the rest.
|
||||
e.g. "fo-bar" vs. "foob-r" on "br"
|
||||
``````
|
||||
- But since fzf is still a fuzzy finder, not an acronym finder, we should also
|
||||
consider the total length of the matched substring. This is why we have the
|
||||
gap penalty. The gap penalty increases as the length of the gap (distance
|
||||
between the matching characters) increases, so the effect of the bonus is
|
||||
eventually cancelled at some point.
|
||||
e.g. "fuzzyfinder" vs. "fuzzy-blurry-finder" on "ff"
|
||||
```````````
|
||||
- Consequently, it is crucial to find the right balance between the bonus
|
||||
and the gap penalty. The parameters were chosen that the bonus is cancelled
|
||||
when the gap size increases beyond 8 characters.
|
||||
|
||||
- The bonus mechanism can have the undesirable side effect where consecutive
|
||||
matches are ranked lower than the ones with gaps.
|
||||
e.g. "foobar" vs. "foo-bar" on "foob"
|
||||
```````
|
||||
- To correct this anomaly, we also give extra bonus point to each character
|
||||
in a consecutive matching chunk.
|
||||
e.g. "foobar" vs. "foo-bar" on "foob"
|
||||
``````
|
||||
- The amount of consecutive bonus is primarily determined by the bonus of the
|
||||
first character in the chunk.
|
||||
e.g. "foobar" vs. "out-of-bound" on "oob"
|
||||
````````````
