    Kotlin KSP — how to automate everything in the world

    Kotlin Symbol Processing (KSP) is a tool for automating boilerplate code generation in Kotlin. Aimed as a lightweight alternative to KAPT, KSP can analyze existing code and generate new classes but cannot modify existing code or analyze method implementations. The post covers the practical usage of KSP for automating navigation in the Compose Navigation library by generating necessary classes, interfaces, and protocols. Key concepts include setting up modules, creating and using annotations, and step-by-step processor implementation.
