+[![Release](https://api.bintray.com/packages/michaelbull/maven/kotlin-inline-logger/images/download.svg)](https://bintray.com/michaelbull/maven/kotlin-inline-logger/_latestVersion) [![Build Status](https://travis-ci.org/michaelbull/kotlin-inline-logger.svg?branch=master)](https://travis-ci.org/michaelbull/kotlin-inline-logger) [![License](https://img.shields.io/github/license/michaelbull/kotlin-inline-logger.svg)](https://github.com/michaelbull/kotlin-inline-logger/blob/master/LICENSE)
+
+A logger facilitating lazily-evaluated log calls via Kotlin's inline [classes][inline-classes] & [functions][inline-functions].
+
+## Installation
+
+```groovy
+repositories {
+    maven { url = 'https://dl.bintray.com/michaelbull/maven' }
+}
+
+dependencies {
+    compile 'com.michael-bull.kotlin-inline-logger:kotlin-inline-logger-jvm:1.0.0'
+}
+```
+
+## Introduction
+
+`kotlin-inline-logger` has been structured as a [`multiplatform project`][mpp].
+Currently the only implementation supports the JVM, utilising [SLF4J][slf4j],
+however in future other platforms can also be supported by implementing the
+necessary platform-specific APIs found in [`src/commonMain`](src/commonMain).
+
+If you would like to implement support for a platform, please don't hesitate
+to open a pull request on [GitHub][github].
+
+### JVM
+
+On the JVM, `kotlin-inline-logger` provides inline functions that delegate
+to [SLF4J][slf4j]. Users migrating from an existing SLF4J solution will find
+their existing calls to methods, e.g. `logger.info("Example")` now marked as
+`@Deprecated`, prompting them to replace their existing code with the
+lazily-evaluated alternatives.
+
+![ReplaceWith example](replacewith-example.gif)
+
+#### Creating loggers
+
+By default, passing no argument when creating an `InlineLogger()` will utilise
+`MethodHandles.lookup()`, introduced in JDK7, to derive the name of the logger
+from the class that created it. This is described in SLF4J's documentation as
+an [idiomatic method of declaring a logger][slf4j-idiom] that is resistant to
+cut-and-pasting between classes.
+
+Named loggers can be created by passing a name:
+
+```kotlin
+val transactionLogger = InlineLogger("DatabaseTransactions")
+```
+
+Class loggers can be created by passing the `::class` reference:
+
+```kotlin
+class TransactionExecutor
+
+val transactionLogger = InlineLogger(TransactionExecutor::class)
+```
+
+
+#### Effectiveness
+
+The code examples below illustrate how the Kotlin you write is compiled to
+interoperable Java, demonstrating how the `expensiveCalculation()` function is
+only invoked and interpolated with the log message if warn-level logging is
+enabled.
+
+This allows you to replace usages of SLF4J's [MessageFormatter][slf4j-formatter],
+with the more idiomatic [string templates][string-templates] Kotlin provides.
+
+##### Kotlin:
+
+```kotlin
+import com.github.michaelbull.logging.InlineLogger
+
+val logger = InlineLogger()
+
+fun expensiveCalculation(): Int {
+    return 1234 * 5678
+}
+
+fun main() {
+    logger.warn { "The result is: ${expensiveCalculation()}" }
+}
+```
+
+##### Compiled Java:
+
+```java
+import com.github.michaelbull.logging.InlineLogger;
+import java.lang.invoke.MethodHandles;
+import kotlin.Metadata;
+import org.jetbrains.annotations.NotNull;
+import org.slf4j.Logger;
+import org.slf4j.LoggerFactory;
+
+public final class ExampleKt {
+    @NotNull
+    private static final Logger logger;
+
+    @NotNull
+    public static final Logger getLogger() {
+        return logger;
+    }
+
+    public static final int expensiveCalculation() {
+        return 1234 * 5678;
+    }
+
+    public static final void main() {
+        Logger $this$iv = logger;
+        boolean $i$f$warn = false;
+        if (InlineLogger.isWarnEnabled-impl((Logger)$this$iv)) {
+            Logger logger = $this$iv;
+            boolean bl = false;
+            String string = "The result is: " + ExampleKt.expensiveCalculation();
+            logger.warn(String.valueOf(string));
+        }
+    }
+
+    public static /* synthetic */ void main(String[] arrstring) {
+        ExampleKt.main();
+    }
+
+    static {
+        boolean $i$f$InlineLogger = false;
+        Logger delegate$iv = LoggerFactory.getLogger(MethodHandles.lookup().lookupClass());
+        logger = InlineLogger.constructor-impl((Logger)delegate$iv);
+    }
+}
+```
