MessengerBot compatibility
Scripts written with the familiar response(room, msg, sender, …) function or API2’s BotManager run too.
And also
- Send photos and files
- Test in the debug room
- Home screen widgets and logs

Familiar code
Bring your existing scripts
With MessengerBot’s legacy style, a single response function is all you need. StarLight calls it whenever a message arrives.
- Receives the familiar arguments: room, msg, sender and more
- Reply to the same room with replier.reply()
- Use ES6 syntax such as Promise and BigInt
// Called for every incoming message
function response(room, msg, sender, isGroupChat,
replier, imageDB, packageName) {
if (msg === "/ping") {
replier.reply("pong! ✦");
}
}plugins {
id("com.android.application")
id("io.github.mooner1022.slplugin") version "0.3.0"
}
starlight {
manifest {
id = "my_plugin"
mainClass = "com.example.MyPlugin"
apiVersion = "0.3.2"
}
}# Deploy to the device and restart StarLight
$ ./gradlew deployDebugSlp -Pstarlight.restartApp=truePlugin development
Build plugins in Kotlin
A StarLight plugin (.slp) is an Android APK with a manifest. The Gradle plugin takes care of building, validating and deploying it to your device. Plugins load in the GitHub build of StarLight.
- Packages every build variant as an .slp file
- Generates and validates the starlight.json manifest
- Turns problems that would only show up at runtime into build errors
- Deploys with adb, restarts the app and streams logcat
