Robotgo

Golang Desktop Automation. Control the mouse, keyboard, bitmap and image, read the screen, process, Window Handle and global event listener.

RobotGo supports Mac, Windows, and Linux(X11); and robotgo supports arm64 and x86-amd64.

Binding:

Robotn, binding JavaScript and other, support more language.

Requirements:

Now, Please make sure Golang, GCC is installed correctly before installing RobotGo.

ALL:

Golang

GCC

For Mac OS X:

Xcode Command Line Tools

For Windows:

MinGW-w64 (Use recommended) or other GCC

For everything else:

GCC, libpng

X11 with the XTest extension (also known as the Xtst library)

Event:

xcb, xkb, libxkbcommon

Ubuntu:

sudo apt install gcc libc6-dev

sudo apt install libx11-dev xorg-dev libxtst-dev libpng++-dev

sudo apt install xcb libxcb-xkb-dev x11-xkb-utils libx11-xcb-dev libxkbcommon-x11-dev
sudo apt install libxkbcommon-dev

sudo apt install xsel xclip

Fedora:

sudo dnf install libxkbcommon-devel libXtst-devel libxkbcommon-x11-devel xorg-x11-xkb-utils-devel

sudo dnf install libpng-devel

sudo dnf install xsel xclip

Installation:

go get github.com/go-vgo/robotgo

It's that easy!

png.h: No such file or directory? Please see issues/47.

Update:

go get -u github.com/go-vgo/robotgo

Note go1.10.x C file compilation cache problem, golang #24355. go mod vendor problem, golang #26366.

Examples:

Mouse

package main

import (
  "github.com/go-vgo/robotgo"

func main() {
  robotgo.ScrollMouse(10, "up")
  robotgo.Scroll(100, 200)

CrossCompiling

Windows64 to windows32

SET CGO_ENABLED=1
SET GOARCH=386
go build main.go

Other to windows

Install Requirements (Ubuntu):

sudo apt install gcc-multilib
sudo apt install gcc-mingw-w64
# fix err: zlib.h: No such file or directory
sudo apt install libz-mingw-w64-dev

Build the binary:

GOOS=windows GOARCH=amd64 CGO_ENABLED=1 CC=x86_64-w64-mingw32-gcc CXX=x86_64-w64-mingw32-g++ go build -x ./
