From 2a9f219d4033e2f04f0ece3a06cd5b985a5ec24f Mon Sep 17 00:00:00 2001 From: Tobias Gesellchen Date: Sat, 10 Jan 2026 12:03:29 +0100 Subject: [PATCH] docs: enhance pkg.go.dev documentation with comprehensive examples - Add root package documentation with quick start guide and feature overview - Enhance client package with detailed usage examples and API coverage - Add comprehensive discovery package documentation with protocol explanations - Create models package documentation explaining all data structures - Add extensive example functions for all major use cases: * Basic device control and playback * Volume, bass, and balance management * Source selection and preset handling * Multiroom zone management * Real-time WebSocket event monitoring * Device discovery with UPnP and mDNS * Error handling and context cancellation - Include code examples for pkg.go.dev's example rendering - Document API endpoints, data structures, and best practices - Add hardware compatibility and implementation notes --- doc.go | 155 ++++++++++++++++++ pkg/client/client.go | 142 +++++++++++++++- pkg/client/example_test.go | 295 ++++++++++++++++++++++++++++++++++ pkg/discovery/example_test.go | 244 ++++++++++++++++++++++++++++ pkg/discovery/unified.go | 107 ++++++++++++ pkg/models/doc.go | 120 ++++++++++++++ 6 files changed, 1062 insertions(+), 1 deletion(-) create mode 100644 doc.go create mode 100644 pkg/client/example_test.go create mode 100644 pkg/discovery/example_test.go create mode 100644 pkg/models/doc.go diff --git a/doc.go b/doc.go new file mode 100644 index 0000000..d285c75 --- /dev/null +++ b/doc.go @@ -0,0 +1,155 @@ +// Package bose-soundtouch provides a comprehensive Go library and CLI tool for controlling Bose SoundTouch devices. +// +// This library implements the complete Bose SoundTouch Web API, enabling programmatic control +// of SoundTouch speakers including playback control, volume management, source selection, +// multiroom zone management, and real-time event monitoring via WebSocket connections. +// +// # Quick Start +// +// Install the library: +// +// go get github.com/gesellix/bose-soundtouch +// +// Basic usage example: +// +// package main +// +// import ( +// "fmt" +// "log" +// +// "github.com/gesellix/bose-soundtouch/pkg/client" +// ) +// +// func main() { +// // Create a client for your SoundTouch device +// config := &client.Config{ +// Host: "192.168.1.100", +// Port: 8090, +// } +// client := client.NewClient(config) +// +// // Get device information +// info, err := client.GetInfo() +// if err != nil { +// log.Fatal(err) +// } +// fmt.Printf("Device: %s\n", info.Name) +// +// // Control playback +// err = client.Play() +// if err != nil { +// log.Fatal(err) +// } +// +// // Set volume +// err = client.SetVolume(50) +// if err != nil { +// log.Fatal(err) +// } +// } +// +// # Device Discovery +// +// Automatically discover SoundTouch devices on your network: +// +// import "github.com/gesellix/bose-soundtouch/pkg/discovery" +// +// // Discover devices using UPnP/SSDP +// devices, err := discovery.DiscoverDevices(ctx, 5*time.Second) +// if err != nil { +// log.Fatal(err) +// } +// +// for _, device := range devices { +// fmt.Printf("Found device: %s at %s\n", device.Name, device.Host) +// } +// +// # Real-time Events +// +// Monitor device state changes in real-time using WebSocket connections: +// +// // Subscribe to device events +// events, err := client.SubscribeToEvents(ctx) +// if err != nil { +// log.Fatal(err) +// } +// +// for event := range events { +// switch e := event.(type) { +// case *models.NowPlayingUpdated: +// fmt.Printf("Now playing: %s by %s\n", e.Track, e.Artist) +// case *models.VolumeUpdated: +// fmt.Printf("Volume changed to: %d\n", e.ActualVolume) +// } +// } +// +// # Multiroom Zone Management +// +// Create and manage multiroom zones: +// +// // Create a zone with multiple speakers +// zone := &models.Zone{ +// Master: "192.168.1.100", +// Members: []models.ZoneMember{ +// {IPAddress: "192.168.1.101"}, +// {IPAddress: "192.168.1.102"}, +// }, +// } +// err = client.SetZone(zone) +// +// # CLI Tool +// +// The package includes a comprehensive CLI tool for device control: +// +// # Install the CLI +// go install github.com/gesellix/bose-soundtouch/cmd/soundtouch-cli@latest +// +// # Discover devices +// soundtouch-cli discover devices +// +// # Control a device +// soundtouch-cli --host 192.168.1.100 play start +// soundtouch-cli --host 192.168.1.100 volume set --level 50 +// soundtouch-cli --host 192.168.1.100 source select --source SPOTIFY +// +// # Supported Features +// +// -
