Make it return NULL for a string array in the form of [ NULL ], like the docs say. This also adds an extra safety check for the joiner to be of a reasonable length to avoid overflows.

2018-05-30touchpad: replace the hardcoded thumb threshold with a udev propPeter Hutterer1-0/+25
LIBINPUT_ATTR_THUMB_PRESSURE_THRESHOLD now determines whether we do thumb pressure detection or not. Much better than having a hardcoded default that may or may not be correct on any given device. This patch is likely to break thumb detection on some touchpads, the only property so far is to restore the default of 100 for all Lenovo Thinkpad touchpads. More rules are needed, we'll just wait until someone shouts. https://bugs.freedesktop.org/show_bug.cgi?id=106458 Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>

2017-07-03touchpad: add pressure-base palm detectionPeter Hutterer1-0/+27
If a touch goes past the fixed pressure threshold it is labelled as a palm and stays a palm. Default value is one that works well here on a T440 and is virtually impossible to trigger by a normal finger or thumb. A udev property is exposed so we can handle this in the udev hwdb and the new tool introduce a few commits ago can help finding the palm detection threshold. Unlike the other palm detection features, once a palm goes past the threshold it remains a palm until the touch is released. This means palm overrides any other palm detection features. For code simplicity, we don't combine the states but merely check for pressure before and after the other palm detection functions. If the pressure triggers, it will trigger before anything else. And if something else is already active (e.g. edge where the pressure doesn't work well) it will trigger as soon as the palm is released. The palm threshold should thus be chosen with some room to spare between the highest finger pressure. https://bugs.freedesktop.org/show_bug.cgi?id=94236 Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>

2017-01-30switch: for surface 3 tablets, write the lid open to the devicePeter Hutterer1-0/+2
These tablets only ever give us a close event, the open event is broken. So when we detect keyboard events, fix the kernel device's state by writing the event to the fd. We still sync the lid state manually, in case this fails and we don't get the SW_LID through the normal event sequence. If it works fine, the real open event will just be ignored.

2017-01-26switch: only sync the initial state if we know the state is reliablePeter Hutterer1-0/+17
This changes the default behavior to "disable the touchpad on the first lid close event", thus filtering any laptops where the switch state is buggy and always in "on" state.

2016-11-04evdev: implement support for the MOUSE_WHEEL_CLICK_COUNT propertyPeter Hutterer1-0/+32
Not all mice have a click angle with integer degrees. The new MOUSE_WHEEL_CLICK_COUNT property specifies how many clicks per full rotation, the angle can be calculated from that. See https://github.com/systemd/systemd/pull/4440 for more information CLICK_COUNT overrides CLICK_ANGLE, so we check for the former first and then fall back to the angle if need be.

2015-06-16COPYING: Update boilerplate from MIT X11 to MIT Expat licensePeter Hutterer1-16/+17
To quote Bryce Harrington from [1]: "MIT has released software under several slightly different licenses, including the old 'X11 License' or 'MIT License'. Some code under this license was in fact included in X.org's Xserver in the past. However, X.org now prefers the MIT Expat License as the standard (which, confusingly, is also referred to as the 'MIT License'). See http://cgit.freedesktop.org/xorg/xserver/tree/COPYING When Wayland started, it was Kristian Høgsberg's intent to license it compatibly with X.org. "I wanted Wayland to be usable (license-wise) whereever X was usable." But, the text of the older X11 License was taken for Wayland, rather than X11's current standard. This patch corrects this by swapping in the intended text." libinput is a fork of weston and thus inherited the original license intent and the license boilerplate itself. See this thread on wayland-devel here for a discussion: http://lists.freedesktop.org/archives/wayland-devel/2015-May/022301.html [1] http://lists.freedesktop.org/archives/wayland-devel/2015-June/022552.html Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Benjamin Tissoires <benjamin.tissoires@gmail.com> Acked-by: Jonas Ådahl <jadahl@gmail.com>

2015-04-22evdev: Add support for POINTINGSTICK_CONST_ACCEL udev propertyHans de Goede1-0/+31
There is quite a wide spread in the delta events generated by trackpoints, some generate deltas of 1-2 under normal use, while others generate deltas from 1-20. It is desirable to normalize trackpoint deltas just like we are normalizing mouse deltas to 1000 dpi, so as to give different model laptops aprox. the same trackpoint cursor speed ootb. Recent versions of udev + hwdb set a POINTINGSTICK_CONST_ACCEL udev property which can be used to adjust trackpoints which are too slow / too fast ootb, this commit implements support for that property.

2013-11-17Introduce libinput object managing all input dataJonas Ådahl1-0/+62
Instead of having the user manage added and removed fd's as well as the fd used for creating evdev devices, introduce a libinput object that itself has an epoll fd. The user no longer manages multiple fd's per libinput instance, but instead handles one fd, dispatches libinput when data is available, then reading events using libinput_get_event(). libinput_event's are now per libinstance, but divided into categories. So far the only category is device events. Device events are categorized by the presence of a non-NULL device pointer in the event. The current API usage should look like: struct libinput libinput = ...; struct libinput_event *event; if (libinput_dispatch(libinput) != 0) return -1; while ((event = libinput_get_event(libinput))) { if (event->device) process_device_event(event); free(event); } Signed-off-by: Jonas Ådahl <jadahl@gmail.com>
