ATLParser

actor ATLParser

Overview

The ATL parser converts ATL source files into structured ATL modules that can be executed by the ATL virtual machine. It supports:

• Module declarations with source/target metamodels

• Helper function definitions (context and context-free)

• Matched transformation rules

• Called transformation rules

• Query expressions

• Basic ATL expression syntax

Supported ATL Constructs

• Modules: module ModuleName;

• Create statements: create OUT : Target from IN : Source;

• Helpers: helper def : helperName() : Type = expression;

• Context helpers: helper context Type def : helperName() : Type = expression;

• Matched rules: rule RuleName { from ... to ... }

• Called rules: rule RuleName(params) { to ... }

• Queries: query QueryName = expression;

• Expressions: literals, variables, operations, navigation

Example Usage

let parser = ATLParser()
let module = try await parser.parse(atlFileURL)
