Log TAG Generator

This is an annotation processor that will generate an appropriate log tag for Android Log messages

You can use the library with either the Kotlin Compiler Plugin or an Annotation Processor

Apply the compiler plugin with Gradle

plugins {
    id("com.cmgapps.logtag") version "2.0.0-alpha.1"
}

Now you can use the @LogTag annotation in your source files

@com.cmgapps.LogTag
class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        Log.d(LOG_TAG, "onCreate")
    }
}

The compiler will generate a private property LOG_TAG with the class' name that you can use as the tag for your log messages.

dependencies {
    implementation("com.cmgapps.logtag:log-tag:2.0.0-alpha.1")
    ksp("com.cmgapps.logtag:processor:2.0.0-alpha.1")
}

plugins {
    id("com.google.devtools.ksp") version "<ksp-version>"
}

dependencies {
    implementation("com.cmgapps.logtag:log-tag:2.0.0-alpha.1")
    kapt("com.cmgapps.logtag:processor:2.0.0-alpha.1")
}

plugins {
    kotlin("kapt")
}

In your source file add the com.cmgapps.LogTag annotation to the class file you want to have a log tag generated:

@com.cmgapps.LogTag
class SuperImportantClass

• For Kotlin classes this will generate an extension property to you class called LOG_TAG you can then use as the tag for your android log messages.

• For Java it will generate a class called <Classname>LogTag which has a constant field called LOG_TAG you can then import to tag your android log messages

• For Jetpack Compose you can annotate the @Composable function for the processor to generate a class called Composable<Composable function name> with a companion object property LOG_TAG
