fzf - a command-line fuzzy finder [![travis-ci](https://travis-ci.org/junegunn/fzf.svg?branch=master)](https://travis-ci.org/junegunn/fzf) === fzf is a general-purpose command-line fuzzy finder. ![](https://raw.github.com/junegunn/i/master/fzf.gif) Pros ---- - No dependencies - Blazingly fast - The most comprehensive feature set - Flexible layout using tmux panes - Batteries included - Vim/Neovim plugin, key bindings and fuzzy auto-completion 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 git 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 ~/.fzf/install ``` ### Using Homebrew On OS X, you can use [Homebrew](http://brew.sh/) to install fzf. ```sh brew install fzf # Install shell extensions /usr/local/opt/fzf/install ``` ### Vim plugin You can manually add the directory to `&runtimepath` as follows, ```vim " If installed using git set rtp+=~/.fzf " If installed using Homebrew set rtp+=/usr/local/opt/fzf ``` But it's recommended that you use a plugin manager like [vim-plug](https://github.com/junegunn/vim-plug). ```vim Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' } ``` ### 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` - vim-plug: `:PlugUpdate fzf` ### Windows Pre-built binaries for Windows can be downloaded [here][bin]. However, other components of the project may not work on Windows. You might want to consider installing fzf on [Windows Subsystem for Linux][wsl] where everything runs flawlessly. [wsl]: https://blogs.msdn.microsoft.com/wsl/ Building fzf ------------ See [BUILD.md](BUILD.md). Usage ----- fzf will launch curses-based finder, read the list from STDIN, and write the selected item to STDOUT. ```sh find * -type f | fzf > selected ``` Without STDIN pipe, fzf will use find command to fetch the list of files excluding hidden ones. (You can override the default command with `FZF_DEFAULT_COMMAND`) ```sh 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. ```sh vim $(fzf --height 40%) ``` Also check out `--reverse` option if you prefer "top-down" layout instead of the default "bottom-up" layout. ```sh vim $(fzf --height 40% --reverse) ``` You can add these options to `$FZF_DEFAULT_OPTS` so that they're applied by default. ```sh export FZF_DEFAULT_OPTS='--height 40% --reverse' ``` #### Search syntax 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` | 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` | 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. 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='ag -g ""'` - `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% ``` Key bindings for command line ----------------------------- The install script will setup the following key bindings for bash, zsh, and fish. - `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 - Sort is disabled by default to respect chronological ordering - Press `CTRL-R` again to toggle sort - Set `FZF_CTRL_R_OPTS` to pass additional options - `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 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. More tips can be found on [the wiki page](https://github.com/junegunn/fzf/wiki/Configuring-shell-key-bindings). Fuzzy completion for bash and zsh --------------------------------- #### Files and directories Fuzzy completion for files and directories can be triggered if the word before the cursor ends with the trigger sequence which is by default `**`. - `COMMAND [DIRECTORY/][FUZZY_PATTERN]**` ```sh # Files under current directory # - You can select multiple items with TAB key vim ** # Files under parent directory vim ../** # Files under parent directory that match `fzf` vim ../fzf** # Files under your home directory vim ~/** # Directories under current directory (single-selection) cd ** # Directories under ~/github that match `fzf` cd ~/github/fzf** ``` #### Process IDs Fuzzy completion for PIDs is provided for kill command. In this case there is no trigger sequence, just press tab key after kill command. ```sh # Can select multiple processes with or keys kill -9 ``` #### Host names For ssh and telnet commands, fuzzy completion for host names is provided. The names are extracted from /etc/hosts and ~/.ssh/config. ```sh ssh ** telnet ** ``` #### Environment variables / Aliases ```sh unset ** export ** unalias ** ``` #### Settings ```sh # Use ~~ as the trigger sequence instead of the default ** export FZF_COMPLETION_TRIGGER='~~' # Options to fzf command export FZF_COMPLETION_OPTS='+c -x' # Use ag instead of the default find command for listing candidates. # - The first argument to the function is the base path to start traversal # - Note that ag only lists files not directories # - See the source code (completion.{bash,zsh}) for the details. _fzf_compgen_path() { ag -g "" "$1" } ``` #### Supported commands On bash, fuzzy completion is enabled only for a predefined set of commands (`complete | grep _fzf` to see the list). But you can enable it for other commands as well like follows. ```sh # There are also _fzf_path_completion and _fzf_dir_completion complete -F _fzf_file_completion -o default -o bashdefault doge ``` Usage as Vim plugin ------------------- 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 in fullscreen instead of using tmux pane or Neovim split :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. Refer to [the wiki page][fzf-config] for customization. [fzf-config]: https://github.com/junegunn/fzf/wiki/Configuring-Vim-plugin #### `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 | 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` (*Neovim only*) | 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) | Examples can be found on [the wiki page](https://github.com/junegunn/fzf/wiki/Examples-(vim)). #### `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'}, 0)) ``` Tips ---- #### Rendering issues If you have any rendering issues, check the following: 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, `$TERM` should be either `screen` or `screen-256color` 3. Some terminal emulators (e.g. mintty) have problem displaying default background color and make some text unable to read. In that case, try `--black` option. And if it solves your problem, I recommend including it in `FZF_DEFAULT_OPTS` for further convenience. 4. If you still have problem, try `--no-256` option or even `--no-color`. #### Respecting `.gitignore`, `.hgignore`, and `svn:ignore` [ag](https://github.com/ggreer/the_silver_searcher) or [pt](https://github.com/monochromegane/the_platinum_searcher) will do the filtering: ```sh # Feed the output of ag into fzf ag -g "" | fzf # Setting ag as the default source for fzf export FZF_DEFAULT_COMMAND='ag -g ""' # Now fzf (w/o pipe) will use ag instead of find fzf # To apply the command to CTRL-T as well export FZF_CTRL_T_COMMAND="$FZF_DEFAULT_COMMAND" ``` If you don't want to exclude hidden files, use the following command: ```sh export FZF_DEFAULT_COMMAND='ag --hidden --ignore .git -g ""' ``` #### `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 It's [a known bug of fish](https://github.com/fish-shell/fish-shell/issues/1362) that it doesn't allow reading from STDIN in command substitution, which means simple `vim (fzf)` won't work as expected. The workaround is to use the `read` fish command: ```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 -l FZF_CTRL_T_COMMAND "command find -L \$dir -type f 2> /dev/null | sed '1d; s#^\./##'" ``` [License](LICENSE) ------------------ The MIT License (MIT) Copyright (c) 2017 Junegunn Choi
