package main import ( "context" "fmt" "github.com/keybase/go-keybase-chat-bot/kbchat" "github.com/keybase/go-keybase-chat-bot/kbchat/types/chat1" ) func main() { // Connect to Keybase chat chat, err := kbchat.Start(kbchat.RunOptions{ListenOnly: true}) if err != nil { fmt.Printf("error starting chat: %s\n", err) return } // Run a command using context ctx := context.Background() convID := chat.GetConversationID("username") err = chat.SendMessageByConvID(ctx, convID, &chat1.MsgSummary{ Body: "Hello, World!", }) if err != nil { fmt.Printf("error sending message: %s\n", err) return } // Close the chat connection err = chat.Close() if err != nil { fmt.Printf("error closing chat: %s\n", err) return } }In this example, we import the `github.com/keybase/go-keybase-chat-bot/kbchat` package, which provides a Keybase chat bot client in Go. We then use the `kbchat.Start` method to connect to Keybase chat, and the `chat.GetConversationID` method to retrieve the conversation ID for a specific user. Next, we create a new context using `context.Background()` and pass it to the `chat.SendMessageByConvID` method to send a message to the specified conversation ID. Finally, we close the chat connection using the `chat.Close` method. Overall, the `github.com.keybase.cli` package provides an easy-to-use implementation for handling contexts in Go. Its use cases are particularly useful for CLI tools and command-line interfaces.
