spacefn-evdev

This is a little tool to implement the SpaceFn keyboard layout on Linux.

I wanted to try SpaceFn on my laptop, obviously with a built-in keyboard. The only previous Linux implementation I could find requires recompiling the Xorg input driver, which is an impressive effort but is tricky to compile and means restarting my X server every time I want to make a change.

Requirements

• libevdev and its headers or -dev packages on some systems
• uinput /dev/uinput must be present and you must have permission to read and write it

You also need permission to read /dev/input/eventXX.

On my system all the requisite permissions are granted by making myself a member of the input group. You can also just run the program as root.

Building

./build.sh

The compiled binary will be at ./spacefn (symlink to build/spacefn).

Installation

sudo ./install.sh

This will:

1. Install udev rules for uinput and input device access
2. Copy config examples to ~/.config/spacefn/
3. Show instructions for adding your user to the input group

After installation, add your user to the input group and log out/in:

sudo usermod -aG input $USER

Running

./spacefn ~/.config/spacefn/default.cfg

Find your keyboard device:

ls /dev/input/by-id/

Customising

Edit config files in configs/ directory.
