Add udev bits to assign LIBINPUT_DEVICE_GROUP The easiest way to get a device group is by looking at the phys path of the input device (which looks like usb-0000:00:14.0-1/input1) and dropping the /inputX bit. The rest is the same for devices that belong together (except on the Cintiq 22HD Touch). Ideally we could just take ATTRS{phys} but we can't select substrings to drop into ENV so we need to do it ourselves. This patch adds a callout that takes a syspath and prints the mangled path, to be used in LIBINPUT_DEVICE_GROUP. The rule triggers on any device that has a non-zero phys attribute, this groups devices like tablets together but also devices like mice with multiple interfaces.

udev: directly import the device groups No need for the indirection of PROGRAM, then ENV for the output value. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> 2020-02-12 16:51:29 +10:00			`ATTRS{phys}=="?*", IMPORT{program}+="@UDEV_TEST_PATH@libinput-device-group %S%p"`
