This is a collection of examples using Codegen. You can use these examples to learn how to use Codegen and build custom code transformations.

We recommend using uv with Python 3.13 for the best experience.

First, install uv if you haven't already

brew install uv

Create and activate a Python 3.13 virtual environment

uv venv && source .venv/bin/activate

Install the codegen package

uv sync

Each directory contains a self-contained example with:

• A README explaining the transformation
• Sample code to transform
• The Codegen script that performs the transformation

• Documentation
• Getting Started Guide
• Tutorials
• API Reference

Have a useful example to share? We'd love to include it! Please see our Contributing Guide for instructions.
