Clabo is DSL (Domain-Specific Language) for Kotlin which gives you the easiest way to create bot for Telegram messenger.


If you use Gradle, you should add the follow config

repositories {
dependencies {
    compile("org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_version", //probably, you have the kotlin stdlib dependency
            'com.github.ivan_osipov:clabo:0.0.1', //the clabo dependency
            'ch.qos.logback:logback-classic:1.2.3', //any implementation of logging for slf4j

The easiest sample of bot that you can implement below. You should change ‘apiKey’ with your value

fun main(args: Array<String>) {
    bot("apiKey") longPolling {
        onStart { command ->
            command.message answer "Hi, ${command.message.from}"

The Main Idea

I believe automatization moves the world forward. I believe that a business which really helps people at same time does them happier. I see that support teams, shops and different services which work with bots really simplify life of them customers and I want to see the same convenient customer service everywhere and this project is my contribution in shared interest.


Clabo is developed by Ivan Osipov as free and open source project.
