+title: "Google Summer of Code 2023 - KFlogger (Kotlin Multiplatform Flogger)"
+date: 2024-01-08 00:02
+---
+
+The Kotlin Foundation sponsored 4 projects for the Google Summer of Code 2023 and we are excited to announce the completion of the KFlogger project, an experimental Kotlin Multiplatform version of [Google's Flogger logging library](https://github.com/google/flogger)!  The contributor to this project was [Giancarlo Buenaflor](https://www.linkedin.com/in/giancarlo-buenaflor/), a computer science undergraduate and the mentor was Mark Mann, a Kotlin Multiplatform engineer at Google.
+
+## Background
+
+Flogger, Google's default logging framework for JVM projects, opens up new opportunities for efficient cross-platform logging. The KFlogger project aims to enable the integration of Flogger into iOS and JVM, benefitting from the multiplatform capabilities of Kotlin.
+
+KFlogger incorporates the existing JVM Flogger codebase as a Java module, preserving its core functionality. The JVM implementation remains largely untouched and is directly actualized through the actual typealias mechanism. On the iOS side, KFlogger introduces a default logging backend based on OSLog.
+
+Here is a demo of this working on Android and iOS:

+
+## Getting Started
+
+To use KFlogger, add the following dependency to your `commonMain` sourceSet:
+```kotlin
+// Find the latest version on https://mvnrepository.com/artifact/com.giancarlobuenaflor/kflogger
+implementation("com.buenaflor:kflogger:0.0.3")
+```
+
+This will allow you to start simple logging.
+Add the `KFluentLogger` instance to your class and then you can start logging through your common code:
+```kotlin
+import com.giancarlobuenaflor.kflogger.KFluentLogger
+
+class LoggingClass {
+    private val logger = KFluentLogger.forEnclosingClass()
+    
+    fun log() {
+        logger.atWarning().log("string: %s“, “example”)
+        logger.atWarning().log("integer: %d”, 1)
+        logger.atWarning().log(“float: %f, 1.0f)
+        logger.atWarning().log(“%d%% %s, 100, “chance”)
+    }
+}
+```
+
+The source is in a [GitHub repository](https://github.com/buenaflor/KFlogger) and we'd love your feedback and contributions!
+
+Thank you Giancarlo and Mark for helping make Kotlin Multiplatform even better!
