🚀 oak-erlang

Making Erlang processing simple — A high-performance, incremental Erlang parser built on the Oak framework.

🎯 Project Vision

oak-erlang is dedicated to providing industrial-grade parsing support for the Erlang language. By leveraging Rust's high-performance characteristics and Oak's incremental parsing architecture, it can easily handle a variety of application scenarios, from simple script analysis to complex IDE language servers.

✨ Core Features

• ⚡ Blazing Fast: Fully utilizes Rust's performance advantages to achieve sub-millisecond parsing response times.
• 🔄 Incremental Parsing: Built-in support for partial updates, demonstrating extremely high efficiency when processing large files.
• 🌳 High-Fidelity AST: Captures language-specific constructs and trivia (comments/whitespace) for refactoring and analysis.
• 🛡️ Robustness: Features a comprehensive error recovery mechanism, ensuring normal operation even when input is incomplete.
• 🧩 Easy Integration: Designed with high cohesion and low coupling, allowing for quick integration into existing Rust projects.

🏗️ Architecture

oak-erlang follows the modern Green/Red Tree architecture (inspired by Roslyn):

• Green Tree: Immutable, lossless, and syntax-only tree. It captures the full fidelity of the source code, including trivia (comments, whitespace).
• Red Tree: A facade over the Green Tree that provides a convenient, type-safe API for tree traversal and analysis, including parent pointers and absolute offsets.

This design enables efficient incremental parsing and powerful refactoring capabilities.
