🪵 Logger

Minimalistic Logger for Kotlin Multiplatform from one of my projects, shared with the awesome Kotlin community.

Usage

// Initialize
class App : Application() {
    override fun onCreate() {
        initializeLogger {
            registerAndroidLogSink()
            registerPrintlnSink() // default, if no sinks are configured
            registerMemoryRingSink()
            loggableLevel = if (isDebugBuild) Everyting else InfoAndSevere
        }
    }
}

// Use logger
private const val TAG = "Reader"

class Reader {
    init {
        i(TAG) { "created: size=${bytes?.size}" } // info
        d(TAG) { "created: size=${bytes?.size}" } // debug
    }

    suspend fun readData() {
        try {
            httpClient.post("read-data")
        } catch (e: Exception) {
            w(TAG, e) { "read-data failed" } // warning
            e(TAG, e) { "read-data failed" } // error
        }
    }
}
