Keyboard

This module implements support for keyboard events, wrapping the stty utility.

How to Install

go get github.com/hybridgroup/gobot && go install github.com/hybridgroup/gobot/platforms/ardrone

How to Use

Example parsing key events

package main

import (
	"fmt"

	"github.com/hybridgroup/gobot"
	"github.com/hybridgroup/gobot/platforms/keyboard"
)

func main() {
	gbot := gobot.NewGobot()

	keys := keyboard.NewKeyboardDriver("keyboard")

	work := func() {
		gobot.On(keys.Event("key"), func(data interface{}) {
			key := data.(keyboard.KeyEvent)

			if key.Key == keyboard.A {
				fmt.Println("A pressed!")
			} else {
				fmt.Println("keyboard event!", key, key.Char)
			}
		})
	}

	robot := gobot.NewRobot("keyboardbot",
		[]gobot.Connection{},
		[]gobot.Device{keys},
		work,
	)

	gbot.AddRobot(robot)

	gbot.Start()
}

Documentation

Overview

Packge keyboard contains the Gobot drivers for keyboard support.

Installing:

Then you can install the package with:

go get github.com/hybridgroup/gobot && go install github.com/hybridgroup/gobot/platforms/keyboard

Example:

package main

import (
	"fmt"

	"github.com/hybridgroup/gobot"
	"github.com/hybridgroup/gobot/platforms/keyboard"
)

func main() {
	gbot := gobot.NewGobot()

	keys := keyboard.NewKeyboardDriver("keyboard")

	work := func() {
		gobot.On(keys.Event("key"), func(data interface{}) {
			key := data.(keyboard.KeyEvent)

			if key.Key == keyboard.A {
				fmt.Println("A pressed!")
			} else {
				fmt.Println("keyboard event!", key, key.Char)
			}
		})
	}

	robot := gobot.NewRobot("keyboardbot",
		[]gobot.Connection{},
		[]gobot.Device{keys},
		work,
	)

	gbot.AddRobot(robot)

	gbot.Start()
}

Types

type KeyEvent

type KeyEvent struct {
	Bytes bytes
	Key   int
	Char  string
}

func Parse

func Parse(input bytes) KeyEvent

type KeyboardDriver

type KeyboardDriver struct {
	gobot.Eventer
	// contains filtered or unexported fields
}

func NewKeyboardDriver

func NewKeyboardDriver(name string) *KeyboardDriver

func (*KeyboardDriver) Connection

func (k *KeyboardDriver) Connection() gobot.Connection

func (*KeyboardDriver) Halt

func (k *KeyboardDriver) Halt() (errs []error)

Halt stops camera driver

func (*KeyboardDriver) Name

func (k *KeyboardDriver) Name() string

func (*KeyboardDriver) Start

func (k *KeyboardDriver) Start() (errs []error)

Start initializes keyboard by grabbing key events as they come in and publishing a key event
