# Scala Compiler Plugin: Annotation-Based Method AST Rewriting

This repository contains a Scala compiler plugin example that demonstrates basic annotation parsing, AST traversal, and method body replacement. It substitutes the block of a method (DefDef) with an inner method, allowing the original code to be wrapped and additional behavior injected.

## Overview

This plugin showcases:

- Parsing annotations

- Traversing the Abstract Syntax Tree (AST)

- Replacing method bodies (DefDef)

The plugin rewrites annotated methods to include additional behaviour, such as logging or remote execution, without modifying the original method code.
