This package provides Go language bindings to the generic input event
interface in Linux. The *evdev* interface serves the purpose of
passing events generated in the kernel directly to userspace through
character devices that are typically located in `/dev/input/`.

Overview ¶
This package provides bindings to the generic input event interface in Linux. The evdev interface serves the purpose of passing events generated in the kernel directly to userspace through character devices that are typically located in /dev/input/.
Please refer to the godoc examples and the bin/evtest example program.
Example ¶
device, _ := Open("/dev/input/event3")
fmt.Println(device)
// InputDevice /dev/input/event3 (fd 3)
// name Logitech USB Laser Mouse
// phys usb-0000:00:12.0-2/input0
// bus 0x0003, vendor 0x046d, product 0xc069, version 0x110
// events EV_KEY 1, EV_SYN 0, EV_REL 2, EV_MSC 4
fmt.Println(device.Capabilities)
// map[ 4:[4 272 273 274 275 276 277 278 279]
// 0:[0 1 2 4]
// 2:[0 1 6 8 272 273 274 275 276 277 278 279]
// 1:[272 273 274 275 276 277 278 279] ]
fmt.Println(device.ResolveCapabilities())
// map[ 4:[4 272 273 274 275 276 277 278 279]
// 0:[0 1 2 4]
// 2:[0 1 6 8 272 273 274 275 276 277 278 279]
// 1:[272 273 274 275 276 277 278 279] ]
