# Fusuma
 [](https://github.com/iberianpig/fusuma/actions/workflows/main.yml)
Fusuma is multitouch gesture recognizer.
This gem makes your linux able to recognize swipes or pinchs and assign commands to them.
襖(Fusuma) means sliding door used to partition off rooms in a Japanese house.
## Features
- Easy installation with RubyGems
- Define gestures and actions in YAML format
- Sensitivity settings (threshold, interval) for gesture recognition
- Automatic addition of external touchpads
- Feature extension via a [plugin system](https://github.com/iberianpig/fusuma/#fusuma-plugins)
## Installation
### Grant permission to read the touchpad device
**IMPORTANT**: You **MUST** be a member of the **INPUT** group to read touchpad by Fusuma.
```sh
sudo gpasswd -a $USER input
```
Then, You apply the change with no logout or reboot.
```sh
newgrp input
```
**IMPORTANT**: This makes `/dev/input/` readable, so if that's an issue for you for some reason (like for privacy- or securityconcerns etc. or if it causes other parts of your OS to misbehave), **consider this your heads-up.**
For Debian Based Distros (Ubuntu, Debian, Mint, Pop!_OS)
### For Debian Based Distros (Ubuntu, Debian, Mint, Pop!_OS)
#### 1. Install libinput-tools
You need `libinput` release 1.0 or later.
```sh
sudo apt-get install libinput-tools
```
#### 2. Install Ruby
Fusuma runs in Ruby, so you must install it first.
```sh
sudo apt-get install ruby
```
#### 3. Install Fusuma
```sh
sudo gem install fusuma
```
#### 4. Install xdotool (optional)
For sending shortcuts:
```sh
sudo apt-get install xdotool
```
For Arch Based Distros (Manjaro, Arch)
### For Arch Based Distros (Manjaro, Arch)
#### 1. Install libinput.
You need `libinput` release 1.0 or later. This is most probably installed by default on Manjaro
```sh
sudo pacman -Syu libinput
```
#### 2. Install Ruby
Fusuma runs in Ruby, so you must install it first.
```sh
sudo pacman -Syu ruby
```
#### 3. Install Fusuma
**Note:** By default in Arch Linux, when running `gem`, gems are installed per-user (into `~/.gem/ruby/`), instead of system-wide (into `/usr/lib/ruby/gems/`). This is considered the best way to manage gems on Arch, because otherwise they might interfere with gems installed by Pacman. (From Arch Wiki)
To install gems system-wide, see any of the methods listed on [Arch Wiki](https://wiki.archlinux.org/index.php/ruby#Installing_gems_system-wide)
```sh
sudo gem install fusuma
```
#### 4. Install xdotool (optional)
For sending shortcuts:
```sh
sudo pacman -Syu xdotool
```
**For the truly lazy people:** As with pretty much anything else available as Open-Source-Software, you can install Fusuma via a package from the AUR. As off time of writing (March 2023), the package you would want is called `ruby-fusuma`.
Please keep in mind that this community-built package is NOT officially supported here and while it might do the job, it is not the intended way to install.
Installing Fusuma this way means that if things do not work as intended during or after the installation, you are on your own.
So please do not bombard the Issues-Page here on Github if Fusuma isn't working correctly after installing it via the AUR.
Fusuma's plugins as listed below here in this Readme can be installed as optional dependencies also via the AUR, namescheme being `ruby-fusuma-replacewithnameofplugin`.
For Fedora
### For Fedora
#### 1. Install libinput-tools
You need `libinput` release 1.0 or later.
```sh
sudo dnf install libinput
```
#### 2. Install Ruby
Fusuma runs in Ruby, so you must install it first.
```sh
sudo dnf install ruby
```
#### 3. Install Fusuma
```sh
sudo gem install fusuma
```
#### 4. Install xdotool (optional)
For sending shortcuts:
```sh
sudo dnf install xdotool
```
### Touchpad not working in GNOME
Ensure the touchpad events are being sent to the GNOME desktop by running the following command:
```sh
gsettings set org.gnome.desktop.peripherals.touchpad send-events enabled
```
## Usage
```sh
fusuma
```
## Update
```sh
sudo gem update fusuma
```
## Customize Gesture Mapping
You can customize the settings for gestures to put and edit `~/.config/fusuma/config.yml`.
**NOTE: You will need to create the `~/.config/fusuma` directory if it doesn't exist yet.**
```sh
mkdir -p ~/.config/fusuma # create config directory
nano ~/.config/fusuma/config.yml # edit config file.
```

### About YAML Basic Syntax
- Comments in YAML begins with the `#` character.
- Comments must be separated from other tokens by whitespaces.
- Indentation of whitespace is used to denote structure.
- Tabs are not included as indentation for YAML files.
### Example: Gesture Mapping for Ubuntu
https://github.com/iberianpig/fusuma/wiki/Ubuntu
```yaml
swipe:
3:
left:
command: "xdotool key alt+Right" # History forward
right:
command: "xdotool key alt+Left" # History back
up:
command: "xdotool key super" # Activity
down:
command: "xdotool key super" # Activity
4:
left:
command: "xdotool key ctrl+alt+Down" # Switch to next workspace
right:
command: "xdotool key ctrl+alt+Up" # Switch to previous workspace
up:
command: "xdotool key ctrl+alt+Down" # Switch to next workspace
down:
command: "xdotool key ctrl+alt+Up" # Switch to previous workspace
pinch:
in:
command: "xdotool keydown ctrl click 4 keyup ctrl" # Zoom in
out:
command: "xdotool keydown ctrl click 5 keyup ctrl" # Zoom out
hold:
4:
command: "xdotool key super" # Activity
```

If you have a nice configuration, please share `~/.config/fusuma/config.yml` with everyone.
### Threshold and Interval
if `command:` properties are blank, the swipe/pinch/hold doesn't execute command.
`threshold:` is sensitivity to swipe/pinch/hold. Default value is 1.
If the swipe's threshold is `0.5`, shorten swipe-length by half.
`interval:` is delay between swipes/pinches/hold. Default value is 1.
If the swipe's interval is `0.5`, shorten swipe-interval by half to recognize a next swipe.
### Example of `threshold:` / `interval:` settings
```yaml
swipe:
3:
left:
command: 'xdotool key alt+Right' # threshold: 0.5, interval: 0.75
threshold: 0.5
right:
command: 'xdotool key alt+Left' # threshold: 0.5, interval: 0.75
threshold: 0.5
up:
command: 'xdotool key super' # threshold: 1, interval: 0.75
down:
command: 'xdotool key super' # threshold: 1, interval: 0.75
pinch:
2:
in:
command: "xdotool keydown ctrl click 4 keyup ctrl" # threshold: 0.5, interval: 0.5
out:
command: "xdotool keydown ctrl click 5 keyup ctrl" # threshold: 0.5, interval: 0.5
threshold:
pinch: 0.5
interval:
swipe: 0.75
pinch: 0.5
```
There are three priorities of `threshold:` and `interval:`.
The individual `threshold:` and `interval:` settings (under "direction") have a higher priority than the global one (under "root")
1. child elements in the direction (left/right/down/up → threshold/interval)
1. root child elements (threshold/interval → swipe/pinch/hold)
1. default value (= 1)
### `command:` property for assigning commands
On fusuma version 0.4 `command:` property is available!
You can assign any command each gestures.
**`shortcut:` property is deprecated**, **it was removed on fusuma version 1.0**.
You need to replace to `command:` property.
```diff
swipe:
3:
left:
- shortcut: 'alt+Left'
+ command: 'xdotool key alt+Left'
right:
- shortcut: 'alt+Right'
+ command: 'xdotool key alt+Right'
```
