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.

Compiling

Run make.

Running

Find your keyboard in /dev/input/. The easiest way is to look in /dev/input/by-id; for example, my laptop keyboard is /dev/input/usb-Apple_Inc._Apple_Internal_Keyboard___Trackpad_XXXXXXXXXXXXXXXXXXXX-if01-event-kbd.

Then run the program:

./spacefn /dev/input/usb-Apple_Inc._Apple_Internal_Keyboard___Trackpad_XXXXXXXXXXXXXXXXXXXX-if01-event-kbd

Customising

The key map is in the function key_map().
