Fusuma::Plugin::Remap

A Fusuma plugin for remapping keyboard events into virtual input devices. Compatible with other Fusuma plugins.

THIS PLUGIN IS EXPERIMENTAL.

This plugin empowers users to manipulate keyboard events and convert them into virtual input devices. It is designed to integrate seamlessly with other Fusuma plugins, thus enabling users to construct sophisticated input configurations and achieve distinctive functionalities. A key feature is the dynamic alteration of remapping layers within the Fusuma process, thereby enabling users to adapt their keyboard inputs to suit specific tasks or applications.

Installation

This plugin requires fusuma 2.0

Install dependencies

NOTE: If you have installed ruby by apt, you must install ruby-dev.

$ sudo apt-get install libevdev-dev ruby-dev build-essential

Set up udev rules

fusuma-plugin-remap create virtual input device(fusuma_virtual_keyboard) by uinput. So you need to set up udev rules.

$ echo 'KERNEL=="uinput", MODE="0660", GROUP="input", OPTIONS+="static_node=uinput"' | sudo tee /etc/udev/rules.d/60-udev-fusuma-remap.rules

Then, reload udev rules.

$ sudo udevadm control --reload-rules && sudo udevadm trigger

Install fusuma-plugin-remap

$ sudo gem install fusuma-plugin-remap

Properties

Remap

Currently, remapping is only possible in the thumbsense context. Please install fusuma-plugin-thumbsense

First, add the 'thumbsense' context to ~/.config/fusuma/config.yml. The context is separated by --- and specified by context: { thumbsense: true }.

Example

Set the following code in ~/.config/fusuma/config.yml.

---
context: 
  thumbsense: true

remap:
  J: BTN_LEFT
  K: BTN_RIGHT
  F: BTN_LEFT
  D: BTN_RIGHT
  SPACE: BTN_LEFT

Emergency Stop Keybind for Virtual Keyboard

This plugin includes a special keybind for emergency stop. Pressing this key combination will ungrab the physical keyboard and terminate the Fusuma process. This feature is particularly useful in situations where the plugin or system becomes unresponsive.

How to Use

To execute the emergency stop, press the following key combination(default):

• RIGHTCTRL → LEFTCTRL

Configuration Example

You can configure the emergency stop key in your Fusuma configuration file (~/.config/fusuma/config.yml) as follows:

plugin:
  inputs:
    remap_keyboard_input:
      emergency_ungrab_keys: RIGHTCTRL+LEFTCTRL # <- Set two keys separated by '+' to trigger the emergency stop

This configuration allows you to specify which keys will trigger the emergency stop functionality. It is important to verify this keybind to ensure a swift response during unexpected situations.
