This is a pure Go package for the Linux evdev interface, without cgo dependencies.
The Linux evdev interface is the userspace interface to interact with input devices such as keyboard, mice, joysticks, touchscreens, rotary encoders etc.
The implementation in this package has the following features:
- Query device information such as the name, the physical location, the unique ID, the vendor/product/bus/version IDs
- Query supported event types, codes and device properties
- Query the current status of bit-field based input types (such as keyboard, switches etc)
as well as information on absolute types (
ABS_X, ...) including their min/max values and current state - Grab/Ungrab/Revoke support for exclusive claiming of devices
- Auto-generated
constdefinitions and maps for types and codes from the kernel include headers
go get github.com/holoplot/go-evdev
And then use it in your source code.
import "github.com/holoplot/go-evdev"
To re-generate codes.go from the latest kernel headers, use the following command.
go run build/gen-codes/main.go
You can optionally validate generated string mappings with go run build/gen-codes-validate/main.go
See the code in cmd/evtest for an example.
