AJJScript Compiler

A simple compiler for the AJJScript language that translates source code to JavaScript.

Components

The compiler consists of three main components:

1. Lexer: Tokenizes the source code into a stream of tokens
2. Parser: Converts tokens into an Abstract Syntax Tree (AST)
3. Code Generator: Translates the AST into executable JavaScript code

Code Generator

The code generator is responsible for translating the AST (Intermediate Representation) into JavaScript code. It handles:

• Class definitions with inheritance
• Control flow constructs (if, while)
• Function calls
• Variable bindings
• Basic arithmetic and logical operations

Usage

const { compile } = require('./src');

// Example AJJScript code
const sourceCode = `
  class Person {
    string name;
    
    init(string name) {
      this.name = name;
    }
    
    method sayHello() void {
      println("Hello, " + this.name);
    }
  }
  
  Person p = new Person("World");
  p.sayHello();
`;

// Compile to JavaScript
const jsCode = compile(sourceCode);
console.log(jsCode);

// Execute the generated code
eval(jsCode);
