📚 TAUSCRIPT PROGRAMMING LANGUAGE

Language Overview

TauScript is a modern, privacy-first programming language designed for the TauCore™ ecosystem. It combines the readability of TypeScript with the performance of compiled languages and built-in privacy features.

Key Features

• Type Safety: Compile-time type checking
• Performance: Compiled to native code
• Security: Built-in security features
• Privacy: Privacy-preserving constructs
• AI Integration: Native ML/AI libraries

Syntax and Basic Concepts

Variables and Types

// Variable declarations
let name: string = "TauCore™";
let version: number = 1.0;
let isActive: boolean = true;

// Type inference
let message = "Hello, World!"; // string
let count = 42; // number
let enabled = true; // boolean

// Arrays and collections
let numbers: number[] = [1, 2, 3, 4, 5];
let names: string[] = ["Alice", "Bob", "Charlie"];

// Objects and structs
struct User {
    id: string;
    name: string;
    email: string;
    isActive: boolean;
}

let user: User = {
    id: "123",
    name: "John Doe",
    email: "john@example.com",
    isActive: true
};

Functions and Control Flow

// Function definitions
fn greet(name: string): string {
    return "Hello, " + name + "!";
}

// Arrow functions
let add = (a: number, b: number): number => a + b;

// Control flow
if (user.isActive) {
    io.println("User is active");
} else {
    io.println("User is inactive");
}

// Loops
for (let i = 0; i < numbers.length; i++) {
    io.println(numbers[i]);
}

// Enhanced for loop
for (let number in numbers) {
    io.println(number);
}

Error Handling

// Try-catch blocks
try {
    let result = riskyOperation();
    io.println("Success: " + result);
} catch (error: Error) {
    io.println("Error: " + error.message);
}

// Optional types
let maybeValue: string? = getValue();
if (maybeValue != null) {
    io.println("Value: " + maybeValue);
}

Privacy-Preserving Features

Privacy Types

// Privacy-preserving data types
privacy struct PersonalData {
    name: string;
    email: string;
    phone: string;
}

// Encrypted data types
encrypted struct SensitiveData {
    creditCard: string;
    ssn: string;
    medicalInfo: string;
}

// Zero-knowledge proofs
zkproof struct ProofOfAge {
    age: number;
    proof: string;
}

Privacy-Preserving Operations

// Federated learning
fn federatedLearning(data: EncryptedData[]): Model {
    let model = Model.new();
    
    for (let encryptedData in data) {
        // Process encrypted data without decryption
        model.update(encryptedData);
    }
    
    return model;
}

// Differential privacy
fn differentiallyPrivateQuery(data: Data[]): Result {
    let noise = generateNoise(epsilon: 0.1);
    let result = query(data);
    return result + noise;
}

AI and Machine Learning

Built-in ML Libraries

import std.ml;
import std.ml.privacy;

// Privacy-preserving machine learning
fn trainModel(data: EncryptedData[]): Model {
    let model = Model.new();
    
    // Federated learning
    for (let batch in data) {
        let gradients = model.computeGradients(batch);
        model.update(gradients);
    }
    
    return model;
}

// Differential privacy
fn privateQuery(data: Data[], epsilon: number): Result {
    let result = query(data);
    let noise = laplaceNoise(epsilon);
    return result + noise;
}
