Porting MiniJinja to Go With an Agent

Read Original

The article details Armin Ronacher's experiment using AI agents (Opus 4.5 and GPT-5.2 Codex) to port the MiniJinja template engine from Rust to Go. He explains the test-driven approach, leveraging existing Rust snapshot tests, and using Pi's branching features to manage the session. The process involved minimal active time from the author, with the agent handling most of the coding and test validation.
