Oak Navigation

Core navigation traits and structures for the Oak ecosystem, providing "Go to Definition" and "Find References" capabilities.

🎯 Overview

Oak Navigation defines the standard interfaces for navigating through source code. It provides the abstractions needed for cross-referencing symbols across files and projects, supporting the primary navigation features expected in modern IDEs.

✨ Features

Standardized Traits: DefinitionProvider and ReferencesProvider for consistent implementation across languages.
LSP Compatibility: Directly maps to LSP textDocument/definition and textDocument/references.
Location Mapping: Uses standard Location and Position types for precise navigation.
Language Agnostic: Works with any language that implements the Oak Language trait.

🚀 Quick Start

Basic implementation of a definition provider:

use oak_navigation::{DefinitionProvider, Location, Position};
use oak_core::tree::RedNode;
use my_language::MyLanguage;

struct MyNavProvider;

impl DefinitionProvider<MyLanguage> for MyNavProvider {
    fn definition(&self, root: &RedNode<MyLanguage::ElementType>, position: Position) -> Vec<Location> {
        // Resolve symbol at position and return its definition location
        vec![]
    }
}

📋 Examples

Finding References

use oak_navigation::{ReferencesProvider, Location, Position};
use oak_core::tree::RedNode;

impl ReferencesProvider<MyLanguage> for MyNavProvider {
    fn references(
        &self, 
        root: &RedNode<MyLanguage::ElementType>, 
        position: Position, 
        include_declaration: bool
    ) -> Vec<Location> {
        // Search for all usages of the symbol at the given position
        vec![]
    }
}

🏗️ Integration

Oak Navigation is a key part of:

Oak LSP: Powers the navigation requests in language servers.
Oak Symbols: Often works in tandem with symbol providers to build a complete index.
IDE Plugins: Enables "Jump to Definition" (F12) and "Find All References" (Shift+F12).

📊 Performance

Fast Indexing: Designed to work with global symbol indexes for rapid lookup.
Lazy Resolution: Navigation targets are resolved only when requested.
