Fusuma plugin configure app-specific gestures

• Switch gesture mappings by detecting active application.
• Support X11, GNOME Wayland, Hyprland

Run the following code in your terminal.

$ sudo gem install fusuma-plugin-appmatcher

Gnome Wayland version 41 and later does not allow to access information about window or application like focused app. So fusuma-plugin-appmatcher solves this problem via Appmatcher gnome-extension.

$ fusuma-appmatcher --install-gnome-extension

Restart your session(logout/login), then activate Appmatcher on gnome-extensions-app

$ fusuma-appmatcher -l prints Running Application names.

$ fusuma-appmatcher -l
Slack
Google-chrome
Alacritty

You can use these application name to under application: context in config.yml

1. Add the --- symbol to separate the context in config.yml.

2. Add context: property in ~/.config/fusuma/config.yml.

3. Under the context: property, you can set the application: APP_NAME as a value.

• In this context, you can configure mappings to application-specific gestures.
• For example, you can set :Google-chrome, :Alacritty, Org.gnome.Nautilus, and so on.
• You can find property name's hint, with $ fusuma-appmatcher -l

NOTE: The first context separated by --- is the default context

In the following example of config.yml

• On Google-chrome, the three-finger gesture is mapped to open in tab, close tab, back in history, forward in history.
• On Gnome-terminal, the three-finger gesture will be mapped to open in tab, close in tab.

# this is default context
swipe:
  4:
    up:
      sendkey: 'LEFTCTRL+LEFTALT+DOWN'
      keypress:
        LEFTSHIFT:
          sendkey: 'LEFTSHIFT+LEFTCTRL+LEFTALT+DOWN'
    down:
      sendkey: 'LEFTCTRL+LEFTALT+UP'
      LEFTSHIFT:
        sendkey: 'LEFTSHIFT+LEFTCTRL+LEFTALT+UP'
---
context:
  application:  Google-chrome
swipe:
  3:
    left:
      sendkey: 'LEFTALT+RIGHT'
    right:
      sendkey: 'LEFTALT+LEFT'
    up:
      sendkey: 'LEFTCTRL+T'
    down:
      sendkey: 'LEFTCTRL+W'
---
context:
  application:  Gnome-terminal
swipe:
  3: 
    up:
      sendkey: 'LEFTSHIFT+LEFTCTRL+T'
    down:
      sendkey: 'LEFTSHIFT+LEFTCTRL+W'

Requires fusuma v3.12.0 or later

You can specify multiple applications using array format. The gesture will be triggered when any of the listed applications is active.

---
context:
  application:
    - Google-chrome
    - Firefox
swipe:
  3:
    left:
      sendkey: 'LEFTALT+RIGHT'
    right:
      sendkey: 'LEFTALT+LEFT'
    up:
      sendkey: 'LEFTCTRL+T'
    down:
      sendkey: 'LEFTCTRL+W'

Requires fusuma v3.12.0 or later

You can combine application with other context conditions. When multiple keys are specified under context:, all conditions must be satisfied (AND logic).

For example, with fusuma-plugin-thumbsense:

---
context:
  thumbsense: true
  application:
    - Alacritty
    - Gnome-terminal
swipe:
  3:
    up:
      sendkey: 'LEFTSHIFT+LEFTCTRL+T'
    down:
      sendkey: 'LEFTSHIFT+LEFTCTRL+W'

In this example, the gesture is only triggered when:

1. Thumbsense mode is active (finger is touching the touchpad)
2. AND the active application is either Alacritty or Gnome-terminal

This AND logic works with any context plugin that provides context conditions

Currently, this plugin supports X11, GNOME Wayland, and Hyprland. We'd love to expand support to other Wayland compositors (Sway, KDE Plasma, wlroots-based compositors, etc.).

If you're using an unsupported compositor:

• Please open an issue to let us know
• Help with testing and feedback is greatly appreciated
