D4rtRunner class

D4rtRunner - Execute pre-parsed AST trees without analyzer dependency.

This class provides the core interpreter functionality for executing SAstNode trees. Unlike the full D4rt class in tom_d4rt_exec, D4rtRunner works exclusively with pre-parsed AST and does not require the analyzer.

Use Cases

• Execute AST loaded from JSON files
• Execute AST from precompiled scripts
• Embedded interpreter without heavy analyzer dependency

Example:

// From JSON string
final runner = D4rtRunner();
final ast = runner.parseJson(jsonString);
final result = runner.execute(ast: ast);

// From JSON file
final result = await runner.executeFromJsonFile('script.ast.json');

For source code parsing and execution, use the D4rt class from tom_d4rt_exec which provides full integration with tom_ast_generator.
