Oak Symbols

Universal symbol indexing and search engine for the Oak ecosystem.

🎯 Overview

Oak Symbols provides a unified way to identify, collect, and search for symbols (functions, classes, variables, etc.) across source files. It features a UniversalSymbolProvider that can automatically extract symbols from any language that follows Oak's semantic role conventions.

✨ Features

• Universal Provider: Automatically extracts symbols from any Oak-compatible language without custom code.
• Hierarchical Context: Tracks container relationships (e.g., which class a method belongs to).
• LSP Integration: Designed to power workspace/symbol and textDocument/documentSymbol.
• Role-Based Classification: Uses UniversalElementRole for consistent symbol categorization across different languages.

🚀 Quick Start

Using the UniversalSymbolProvider:

use oak_symbols::{UniversalSymbolProvider, SymbolProvider};
use oak_core::tree::RedNode;
use my_language::MyLanguage;

let provider = UniversalSymbolProvider::new();
// let symbols = provider.document_symbols::<MyLanguage>(&root);

📋 Examples

Symbol Information Structure

use oak_symbols::SymbolInformation;
use oak_core::language::UniversalElementRole;
use oak_lsp::Location;

let info = SymbolInformation {
    name: "calculate_total".to_string(),
    role: UniversalElementRole::Definition,
    location: Location { uri: "...".to_string(), range: 10..30 },
    container_name: Some("OrderProcessor".to_string()),
};

🔧 Advanced Features

Semantic Role Extraction

The UniversalSymbolProvider works by inspecting the UniversalElementRole of AST nodes. Any node marked as Definition is automatically indexed as a symbol, and its children are searched for identifiers to use as the symbol name.

🏗️ Integration

• Oak LSP: Powers global workspace symbol search.
• Oak Navigation: Used to resolve symbol names to their definition locations.
• Documentation Generators: Automatically builds indexes of all functions/types in a project.

📊 Performance

• Fast Collection: Optimized tree traversal for symbol extraction.
• Search-Ready: Symbol structures are designed for efficient indexing in search engines.
