Dart support for the Oak language framework.

Welcome to the internal implementation of the Dart parser. This module provides the core logic for tokenizing and parsing Dart source code into a high-fidelity syntax tree.

ยง๐Ÿ“ฆ Core Components

  • Lexer: Tokenizes Dart source code, handling comments, strings, and identifiers with full fidelity.
  • Parser: Implements the Dart grammar, producing a Green Tree that represents the concrete syntax.
  • AST: Provides a type-safe Red Tree facade for easy traversal and analysis.
  • Language: Defines the DartLanguage configuration and integration with the Oak framework.

ยง๐Ÿš€ Usage Example

ยงBasic Parsing

use oak_dart::{DartParser, SourceText, DartLanguage};

fn parse_dart_code(code: &str) {
    let source = SourceText::new(code);
    let config = DartLanguage::new();
    let parser = DartParser::new(&config);
    let result = parser.parse(&source);

    if result.is_success() {
        let root = result.root();
        println!("AST Root: {:?}", root);
    }
}

ยงIncremental Parsing

use oak_dart::{DartParser, SourceText, DartLanguage};

fn incremental_update(old_code: &str, new_code: &str) {
    let config = DartLanguage::new();
    let mut parser = DartParser::new(&config);
    
    // Initial parse
    let initial_source = SourceText::new(old_code);
    let _ = parser.parse(&initial_source);
    
    // Incremental update
    let updated_source = SourceText::new(new_code);
    let result = parser.parse(&updated_source);
    
    if result.is_success() {
        println!("Incremental parse completed successfully.");
    }
}

ยง๐Ÿ” Diagnostics

The parser provides detailed diagnostics for syntax errors, including error ranges and helpful messages.

let result = parser.parse(&source);
for diagnostic in result.diagnostics() {
    println!("Error at {:?}: {}", diagnostic.range(), diagnostic.message());
}
