```

  sudo gpasswd -a $USER input
  newgrp input

Optional: Enable touchpad events

  gsettings set org.gnome.desktop.peripherals.touchpad send-events enabled

Setup

Download Swipe to a folder. (Either download the latest build from the bin folder, or clone this repo, or download and extract the Zip file.)
```
  $ wget https://github.com/evuraan/Swipe/blob/main/bin/swipe?raw=true -O swipe 
  $ chmod 775 swipe 
```
Launch swipe. In most cases Swipe will look for and find everything it needs, otherwise you can use the options and/or a config file.

See your distro's documentation to setup Swipe as a Startup Application - an application that starts when a desktop user logs in.

Usage:

$ ./swipe -h
Usage: ./swipe
  -h  --help             print this usage and exit
  -v  --version          print version information and exit
  -s  --sampleCfg        show sample config
  -d  --debug            show verbose output
  -c  /etc/ku.conf       config file to use
  -k  --keys             show available keys
  -i  /dev/input/event1  kbd device to use
  -a  --available        show available devices
  -q  --noIndicator      disable status icon

If no config file is specified, Swipe would use a default configuration.
If an appropriate kbd device cannot be found, Swipe will ask you to specify a suitable device using the -i option.

Config

Generate a sample config file with -s option. Here are some other config examples.

$ ./swipe -s

3up:        "KEY_SPACE"
3down:      "KEY_LEFTSHIFT + KEY_SPACE"

# 4 button touchpad gestures
4right:     "KEY_MUTE"
4left:      "KEY_MUTE"
4up:        "KEY_VOLUMEUP"
4down:      "KEY_VOLUMEDOWN"

Run with -d option to have debug info onto the terminal:

$ ./swipe -d -c /tmp/swipe.conf
Fri Sep 03 19:07:12 2021 Swipe/3.01e Read 14 values from the config file
Fri Sep 03 19:07:12 2021 Swipe/3.01e 2 key touchpad events: map[LEFT:KEY_LEFTALT + KEY_RIGHT RIGHT:KEY_RIGHTALT + KEY_LEFT]
Fri Sep 03 19:07:12 2021 Swipe/3.01e 3 key touchpad events: map[DOWN:KEY_LEFTSHIFT + KEY_SPACE LEFT:KEY_LEFTALT + KEY_RIGHT RIGHT:KEY_LEFTALT + KEY_LEFT UP:KEY_SPACE]
Fri Sep 03 19:07:12 2021 Swipe/3.01e 4 key touchpad events: map[DOWN:KEY_END LEFT:KEY_LEFTALT + KEY_RIGHT RIGHT:KEY_LEFTALT + KEY_LEFT UP:KEY_HOME]
