🚀 Oak C Parser

Crates.io Documentation

Legacy Performance, Modern Tooling. oak-c is a high-performance, incremental C parser built on the Oak framework. Optimized for systems programming, legacy codebase analysis, and real-time developer tooling, it brings modern infrastructure to the C ecosystem.

✨ Core Features

  • ⚡ Blazing Fast: Built in Rust for sub-millisecond parsing, essential for real-time feedback in massive systems-level codebases.
  • 🔄 Truly Incremental: Re-parse only what changed. Ideal for massive translation units and responsive IDE feedback.
  • 🛡️ Industrial-Grade Fault Tolerance: Gracefully handles syntax errors, providing precise diagnostics for complex C code.
  • 🌳 High-Fidelity AST: Captures every detail of C, including declarations, expressions, preprocessor awareness, and trivia.
  • Full C Support: Comprehensive coverage of functions, structs, unions, and enums.
  • Preprocessor Aware: Robust handling of directives and macro definitions.
  • 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.
