JavierSegoviaCordoba/kopy ★ 295 8 APPLICATION

Kopy is a Kotlin compiler plugin that generates an ergonomic DSL for immutable updates on data classes. It adds `copy`, `set`, `update`, and `updateEach` functions to data classes annotated with `@Kopy`, enabling deep nested property changes without manual `copy` chains. The plugin uses `kotlin.concurrent.atomics.AtomicReference` for thread-safe snapshots and integrates as a Gradle plugin. The codebase is a multi-module Gradle project with a compiler plugin module (`kopy-compiler`), a Gradle plugin module (`kopy-gradle-plugin`), a runtime annotations module (`kopy-runtime`), and a configuration enums module (`kopy-args`). It includes extensive test data for FIR and IR transformations, covering diagnostics, box tests, visibility, inheritance, serialization, and edge cases. The project is actively maintained, with a well-structured architecture and high test coverage.
