An annotation processor to generate Proxy-based helper methods for creating Kotlin annotations at runtime. Based on Google's AutoAnnotation processor for Java.

aak's Issues

Snapshots

Extract core function generation to core artifact

It should have a simple API where you give it a target annotation TypeElement or TypeSpec (from metadata) and it gives you back a function implementation

Document caveats

• Reified functions aren't possible from annotation processing because they're not visible (synthetic)
• Others?

Use optimized toString

Right now we generate something like this: "AakProxy_Names#nameAnnotation"

We should generate an optimized toString() for better string pooling like this

buildString { append("AakProxy").append("_").append("Names").append("#").append("nameAnnotation") }

Support annotation on annotation classes

Given

@AutoAnnotation
annotation class Named(val name: String)

Generate an extension function directly

fun KClass<Named>.aakInstance(name: String): Named {
  // ...
}

Support array types

This may Just Work right now, but needs a test
