Evdev.Uinput

Create virtual input devices.

Documentation

data Device

A uinput device.

newDevice

Arguments

:: ByteString

Device name

-> DeviceOpts

-> IO Device

Create a new uinput device.

writeEvent :: Device -> EventData -> IO ()

Write a single event. Doesn't issue a sync event, so: writeEvent dev e /= writeBatch dev [e].

writeBatch :: Foldable t => Device -> t EventData -> IO ()

Write several events followed by a SynReport.

data EventData

An input event, without the timestamp. Each constructor corresponds to one event type, except for UnknownEvent.

Constructors

SyncEvent SyncEvent

KeyEvent Key KeyEvent

RelativeEvent RelativeAxis EventValue

AbsoluteEvent AbsoluteAxis EventValue

MiscEvent MiscEvent EventValue

SwitchEvent SwitchEvent EventValue

UnknownEvent Word16 EventCode EventValue

We include this primarily so that fromCEvent can be well-defined - let us know if you ever actually see one emitted by a device, as it would likely indicate a shortcoming in the library.
