📄 中文摘要
Ladybird 团队在经过几年的探索后，决定从 Swift 切换到 Rust 作为其主要编程语言，原因在于 Rust 提供了内存安全的特性。此转变的第一步是对一个关键库进行 AI 辅助的移植，目标是 LibJS，这是 Ladybird 的 JavaScript 引擎。LibJS 的词法分析器、解析器、抽象语法树和字节码生成器相对独立，并且通过 test262 具有广泛的测试覆盖，这使其成为一个自然的起点。此案例展示了在复杂编码项目中，AI 编程代理的高级应用。

Ladybird adopts Rust, with help from AI
The Ladybird team has transitioned from Swift to Rust after several years of hoping for improved platform support outside the Apple ecosystem. Rust was chosen for its memory safety features. The first step in this transition involved an AI-assisted port of a critical library, specifically targeting LibJS, Ladybird's JavaScript engine. The lexer, parser, AST, and bytecode generator of LibJS are relatively self-contained and have extensive test coverage through test262, making them a natural starting point. This case study highlights the advanced use of coding agents in ambitious coding projects.
