This is the minimum framework to support new clients, added devices and pointer relative motion events. It's missing a bunch of checks and verification, most of the server hooks aren't there yet, the only implementation is a UNIX socket and the protocol is plain text (but at least the last two makes it netcat-compatible). Protocol is plain text for now and interaction is like this (S is server, C is client): S: hello C: connect myclientname S: connected C: add 2 4 S: accept 2 C: rel 2 -1 1 C: rel 2 5 4 Where the last two lines are: add device with id 2 and capability mask 0x4, send a relative pointer motion event for device 2 with coordinates -1/1, then 5/4. The implementation relies heavily on some abstraction and macros galore, see the various util-* files. These are largely copied from libinput, with a few parts removed and a few other parts added.
