Working Example

This is a basic working example.

fun translateToEnglish() {

    val klaudeClient = KlaudeClient.Builder()
        .key("YOUR_API_KEY")
        .model("claude-2")
        .maxTokensToSample(1000)
        .build()
    val text = "Olá, tudo bem?"
    klaudeClient.complete("Translate to English: $text") { result ->
        println(result ?: "[empty]")
    }
}

fun chat() {
    val scan = Scanner(System.`in`)

    val klaude = KlaudeClient.Builder()
        .model("claude-2")
        .key("YOUR_API_KEY")
        .maxTokensToSample(500)
        .build()

    val messages = mutableListOf(KlaudeMessage("You are a helpful assistant", KlaudeMessageType.USER))

    println("Start chatting, type 'exit' or 'quit' to finish:\n")

    while (true) {

        println("Human:")

        val input = scan.nextLine().trim()

        if (input.isBlank()) {
            continue
        }

        if (input == "exit" || input == "quit") {
            break
        }
        messages.add(KlaudeMessage(input, KlaudeMessageType.USER))

        klaude.chat(messages) { reply ->
            if (!reply.isNullOrBlank()) {
                messages.add(KlaudeMessage(reply.trim(), KlaudeMessageType.ASSISTANT))
                println("Assistant:\n${reply.trim()}")
            }
        }
    }
    println("DONE")
