Low latency detection of single-click, double-click, long-click and dragging.
Each event is detected in a mutually exclusive manner, so e.g. a double-click won't also detect single-click events.

Dragging will emit a start and stop event, as well as a drag event that includes a change in coordinates which can be used for detecting gestures.

Beware that window dragging interferes with gesture detection unless you use --no-window-dragging. See ignore_left_single_long_while_window_dragging option for more information.

1. Save pointer-event.lua to your scripts directory.
2. Configure the events you want to listen to in your pointer-event.conf

Upon detecting an event the corresponding command from the pointer-event.conf in your script-opts directory (next to the scripts directory, create if it doesn't exist) gets executed.

The command configuration follows the <button>_<event_type>=command pattern.

The available buttons are

left
right
mid

Touch input is recognized as left. Each of those can listen to the following event types

single
double
long
drag_start
drag_end
drag

drag appends the change in pointer position dx dy to the command.

Additionally there are also

long_click_time
double_click_time
drag_distance
margin_left
margin_right
margin_top
margin_bottom
ignore_left_single_long_while_window_dragging

They all have sensible default values with double_click_time following input-doubleclick-time. Time is interpreted as milliseconds.
drag_distance determines how far the input has to be dragged to count as a drag instead of a click/touch. The margin_* options allow for easier interaction with the osd without triggering any events.

It can be desirable to have window dragging enabled and also want gesture detection. ignore_left_single_long_while_window_dragging exists to avoid triggering single and long click events while dragging the window. Those events will still work while in fullscreen or maximized mode.
Keep in mind that window dragging already starts on button down, even without moving the mouse/finger.

Beware of conflicts with mpvs built-in key bindings as well as your key configuration in input.conf.

touch-gestures is an example of what can be done with this.
