# fzf
|
||||
|
||||
This plugin enables [junegunn's fzf](https://github.com/junegunn/fzf) fuzzy auto-completion and key bindings
|
||||
This plugin tries to find [junegunn's fzf](https://github.com/junegunn/fzf) based on where
|
||||
it's been installed, and enables its fuzzy auto-completion and key bindings.
|
||||
|
||||
To use it, add `fzf` to the plugins array in your zshrc file:
|
||||
|
||||
```zsh
|
||||
plugins=(... fzf)
|
||||
```
|
||||
|
||||
## Settings
|
||||
|
||||
Add these before the `plugins=()` line in your zshrc file:
|
||||
All these settings should go in your zshrc file, before Oh My Zsh is sourced.
|
||||
|
||||
### `FZF_BASE`
|
||||
|
||||
Set to fzf installation directory path:
|
||||
|
||||
```zsh
|
||||
# Set fzf installation directory path
|
||||
# export FZF_BASE=/path/to/fzf/install/dir
|
||||
|
||||
# Uncomment to set the FZF_DEFAULT_COMMAND
|
||||
# export FZF_DEFAULT_COMMAND='<your fzf default commmand>'
|
||||
|
||||
# Uncomment the following line to disable fuzzy completion
|
||||
# DISABLE_FZF_AUTO_COMPLETION="true"
|
||||
|
||||
# Uncomment the following line to disable key bindings (CTRL-T, CTRL-R, ALT-C)
|
||||
# DISABLE_FZF_KEY_BINDINGS="true"
|
||||
export FZF_BASE=/path/to/fzf/install/dir
|
||||
```
|
||||
|
||||
| Setting | Example value | Description |
|
||||
|-----------------------------|----------------------------|-------------------------------------------------------------|
|
||||
| FZF_BASE | `/path/to/fzf/install/dir` | Set fzf installation directory path (**export**) |
|
||||
| FZF_DEFAULT_COMMAND | `fd --type f` | Set default command to use when input is tty (**export**) |
|
||||
| DISABLE_FZF_AUTO_COMPLETION | `true` | Set whether to load fzf auto-completion |
|
||||
| DISABLE_FZF_KEY_BINDINGS | `true` | Set whether to disable key bindings (CTRL-T, CTRL-R, ALT-C) |
|
||||
### `FZF_DEFAULT_COMMAND`
|
||||
|
||||
Set default command to use when input is tty:
|
||||
|
||||
```zsh
|
||||
export FZF_DEFAULT_COMMAND='<your fzf default commmand>'
|
||||
```
|
||||
|
||||
If not set, the plugin will try to set it to these, in the order in which they're found:
|
||||
|
||||
- [`rg`](https://github.com/BurntSushi/ripgrep)
|
||||
- [`fd`](https://github.com/sharkdp/fd)
|
||||
- [`ag`](https://github.com/ggreer/the_silver_searcher)
|
||||
|
||||
### `DISABLE_FZF_AUTO_COMPLETION`
|
||||
|
||||
Set whether to load fzf auto-completion:
|
||||
|
||||
```zsh
|
||||
DISABLE_FZF_AUTO_COMPLETION="true"
|
||||
```
|
||||
|
||||
### `DISABLE_FZF_KEY_BINDINGS`
|
||||
|
||||
Set whether to disable key bindings (CTRL-T, CTRL-R, ALT-C):
|
||||
|
||||
```zsh
|
||||
DISABLE_FZF_KEY_BINDINGS="true"
|
||||
```
