Enterprise-Grade Performance for the JVM Ecosystem. oak-java is a high-performance, incremental Java parser built on the Oak framework. Optimized for modern Java features and large-scale enterprise systems, it delivers the speed and accuracy needed for real-time developer tools.

✨ Core Features

  • ⚡ Blazing Fast: Built in Rust for sub-millisecond parsing, essential for real-time feedback in massive enterprise codebases.
  • 🔄 Truly Incremental: Re-parse only what changed. Ideal for massive Java projects and responsive IDE feedback.
  • 🛡️ Industrial-Grade Fault Tolerance: Gracefully handles syntax errors, providing precise diagnostics for Java code.
  • 🌳 High-Fidelity AST: Captures every detail of Java, including records, annotations, and trivia.
  • Full Java Support: Comprehensive coverage of records, sealed classes, and modules.
  • IDE Ready: Designed from the ground up for Language Server Protocol (LSP) and MCP integration.
  • Lossless Syntax: Retains all source details, making it perfect for automated refactoring and formatting.

🏗️ Modern Architecture

Leveraging the Green/Red Tree pattern (similar to Roslyn and rust-analyzer):

  1. Efficient Immutability: Share nodes across tree versions without expensive copies.
  2. Type-Safe API: Easy traversal with strongly-typed nodes.
  3. Zero-Copy Trivia: Efficiently manage comments and whitespace.
