tmux-fuzzback uses a fuzzy finder to search terminal scrollback buffer, and

jump to selected position.

## Attribution



This plugin would not be possible without the work done in

[copycat](https://github.com/tmux-plugins/tmux-copycat). Go download it, use

it, and give it some love. I also drew more than a little inspiration from

[tmux-fzf-url](https://github.com/wfxr/tmux-fzf-url). Huge thanks to both.



## Requirements



- [tmux](https://github.com/tmux/tmux) version >= [2.4](https://github.com/tmux/tmux/releases/tag/2.4)

- A fuzzy finder

  - [fzf](https://github.com/junegunn/fzf)

  - [skim](https://github.com/lotabout/skim) - Requires extra [configuration](#fuzzy-finder)



## Installation



### Using [Tmux Plugin Manager](https://github.com/tmux-plugins/tpm) (recommended)



```

set -g @plugin 'roosta/tmux-fuzzback'

```



### Manually

```shell

git clone https://github.com/roosta/tmux-fuzzback.git

```



Add this to the bottom of `.tmux.conf`

```

run-shell ~/path/to/repo/fuzzback.tmux

```



Reload TMUX env

```shell

tmux source-file ~/.tmux.conf

```



## Usage



To use tmux-fuzzback, start it in a tmux session by typing prefix +

?. Now you can start fuzzy searching in your scrollback buffer using

fzf.



## Options

### Fuzzy finder



Fuzzback uses `fzf` as default, but you can set it to `sk` if you'd rather use [skim](https://github.com/lotabout/skim)



```tmux

set -g @fuzzback-finder 'sk'

```



Fuzzback was built using fzf, and only later did I add support for skim. These

two finders seem mostly comparable, although I might have missed something.

Please open an issue if you find any problems with this or other.



Additionally the popup window doesn't seem to work in sk-tmux, I'm unable to

open it on `tmux next-3.4` and `sk 0.10.2`, so it isn't currently configured to

work.



### Key binding



The default key-binding is `?` preceded by a prefix, it can be modified by

setting value to `@fuzzback-bind` in the tmux config like this:



```tmux

set -g @fuzzback-bind s

```



Make sure this setting is set before loading the plugin.



### Enable popup



You can enable tmux popup by setting this variable in your tmux conf.  Keep in

mind that only recent versions `3.2` and above of tmux support this.



```tmux

set -g @fuzzback-popup 1

```



***Only works with fzf for the time being***



### Hide preview



Preview is shown by default, but you can hide it initially by setting

`fuzzback-hide-preview` to `1`.



```tmux

set -g @fuzzback-hide-preview 1

```



You can still toggle it back with your preferred keybinding (fzf default ctrl+p)



### Popup size



You can set the popup size with this option.



```tmux

set -g @fuzzback-popup-size '90%'

```



### Finder layout



You can reverse the direction of selected finder by setting this variable. The

default is `default`



```tmux

set -g @fuzzback-finder-layout 'reverse'

```



### Finder bind



If you want to bind some keybinding using sk/fzf --bind that's only used in

fuzzback set this variable.



```tmux

set -g @fuzzback-finder-bind 'ctrl-y:execute-silent(echo -n {3..} | xsel -ib)+abort'

```



This will copy the line matches in selected finder to the clipboard if `xsel` is available.



Refer documentation for more:

- [fzf documentation](https://github.com/junegunn/fzf#executing-external-programs)

- [skim documentation](https://github.com/lotabout/skim#keymap)



#### Toggling sort



If you need to toggle sort on and off you could add this to your fuzzback config



- ref: https://github.com/roosta/tmux-fuzzback/issues/23



```tmux

set -g @fuzzback-finder-bind 'ctrl-s:toggle-sort'

```



### FZF colors



You can add colors to fuzzback as you do with `fzf`. 



```tmux

set -g @fuzzback-fzf-colors 'bg+:#100E23,gutter:#323F4E,pointer:#F48FB1,info:#ffe6b3,hl:#F48FB1,hl+:#63f2f1'

```



All highlight options can be found in fzf's [man page](https://www.mankier.com/1/fzf#--color).



### Keybind table



Normally the fuzzback keybind will go into the `prefix` table, but if you want

to activate fuzzback without typing the prefix, you can change the table here.

Say you wanted to activate fuzzback without prefix:



```tmux

# this is the same as bind-key -n

set -g @fuzzback-table 'root'

```

Make sure this option, same as keybind, is set before loading the plugin.



## Limitations



### Column movement



Depending on the complexity of the search query, fuzzback might not know what

column to move to, and will place you at the start of the line unless a literal

match can be found.



## Developing



You can run tests locally using [Vagrant](https://www.vagrantup.com/) by calling:



```sh

# cd project root

./run_tests

```
