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.
- libevdev and its headers or -dev packages on some systems
- uinput
/dev/uinputmust 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.
Run make.
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
The key map is in the function key_map().
