Peter Hutterer dc249b0ffe tools/debug-events: add ability to compress motion events 
If --compress-motion-events is given (and stdout is a tty) reduce
the output printed to one line per repeated motion/axis/scroll sequence
(with a count). Example output:
 event6   POINTER_MOTION          108 +1.912s	 1.00/ -1.00 ( +1.00/ -1.00))
 event6   POINTER_BUTTON              +2.008s	BTN_LEFT (272) pressed, seat count: 1
 event6   POINTER_BUTTON              +2.074s	BTN_LEFT (272) released, seat count: 0
 event6   POINTER_MOTION           39 +5.249s	 0.00/  0.99 ( +0.00/ +1.00)
 event6   POINTER_BUTTON              +5.385s	BTN_LEFT (272) pressed, seat count: 1
 event6   POINTER_MOTION           66 +6.031s	-1.00/  0.00 ( -1.00/ +0.00)
 event6   POINTER_BUTTON              +6.401s	BTN_LEFT (272) released, seat count: 0

The event count (108, 39 and 66) is only printed for more than one event
in sequence so the output is otherwise identical (but 4 spaces wider
now)

If stdout is not a tty the event count is printed but no compression
happens since we rely on a ansi escape sequence for that. Could be fixed
by changing the current print statements to print a \n before the
current event instead of at the end of the current line.

This makes debugging events easier as button events and similar are no
longer obscured by pages of motion events in between.

libinput

libinput is a library that provides a full input stack for display servers and other applications that need to handle input devices provided by the kernel.

libinput provides device detection, event handling and abstraction to minimize the amount of custom input code the user of libinput needs to provide the common set of functionality that users expect. Input event processing includes scaling touch coordinates, generating relative pointer events from touchpads, pointer acceleration, etc.

User documentation

Documentation explaining features available in libinput is available here.

This includes the FAQ and the instructions on reporting bugs.

Reporting Bugs

Bugs can be filed on freedesktop.org GitLab: https://gitlab.freedesktop.org/libinput/libinput/issues/

Where possible, please provide the libinput record output of the input device and/or the event sequence in question.

See https://wayland.freedesktop.org/libinput/doc/latest/reporting-bugs.html for more info.

Documentation

Examples of how to use libinput are the debugging tools in the libinput repository. Developers are encouraged to look at those tools for a real-world (yet simple) example on how to use libinput.
