Steam for Go

This library implements Steam's protocol to allow automation of different actions on Steam without running an actual Steam client. It is based on SteamKit2, a .NET library.

In addition, it contains APIs to Steam Community features, like trade offers and inventories.

Some of the currently implemented features:

  • Trading and trade offers, including inventories and notifications
  • Friend and group management
  • Chatting with friends
  • Persona states (online, offline, looking to trade, etc.)
  • SteamGuard
  • Team Fortress 2: Crafting, moving, naming and deleting items

If this is useful to you, there's also the go-steamapi package that wraps some of the official Steam Web API's types.

Installation

go get github.com/Philipp15b/go-steam

Usage

You can view the documentation with the godoc tool or online on godoc.org.

You should also take a look at the following sub-packages:

Updating go-steam to a new SteamKit version

To update go-steam to a new version of SteamKit, do the following:

go get github.com/golang/protobuf/protoc-gen-go/
git submodule init && git submodule update
cd generator
go run generator.go clean proto steamlang

Make sure that $GOPATH/bin / protoc-gen-go is in your $PATH. You'll also need protoc, the protocol buffer compiler. At the moment, we use Protocol Buffers 2.6.1 with proco-gen-go-2402d76.

To compile the Steam Language files, you also need the .NET Framework on Windows or mono on other operating systems.

Apply the protocol changes where necessary.

Documentation

Overview

This package allows you to automate actions on Valve's Steam network. It is a Go port of SteamKit.

To login, you'll have to create a new Client first. Then connect to the Steam network and wait for a ConnectedCallback. Then you may call the Login method in the Auth module with your login information. This is covered in more detail in the method's documentation. After you've received the LoggedOnEvent, you should set your persona state to online to receive friend lists etc.

package main

import (
	"github.com/Philipp15b/go-steam"
	"github.com/Philipp15b/go-steam/protocol/steamlang"
	"io/ioutil"
	"log"
)

func main() {
	myLoginInfo := new(steam.LogOnDetails)
	myLoginInfo.Username = "Your username"
	myLoginInfo.Password = "Your password"

	client := steam.NewClient()
	client.Connect()
	for event := range client.Events() {
		switch e := event.(type) {
		case *steam.ConnectedEvent:
			client.Auth.LogOn(myLoginInfo)
		case *steam.MachineAuthUpdateEvent:
			ioutil.WriteFile("sentry", e.Hash, 0666)
		case *steam.LoggedOnEvent:
			client.Social.SetPersonaState(steamlang.EPersonaState_Online)
		case steam.FatalErrorEvent:
			log.Print(e)
		case error:
			log.Print(e)
		}
	}
}

Events

go-steam emits events that can be read via Client.Events(). Although the channel has the type interface{}, only types from this package ending with "Event" and errors will be emitted.
