Toolb0x

A comprehensive C++20 modular utility library providing essential tools for modern C++ development. Toolb0x offers a collection of header-only modules covering algorithms, asynchronous programming, data structures, and system utilities.

🚀 Features

• Modular Design: 25+ independent C++20 modules for selective usage
• Header-Only: Zero-compilation dependency, just import and use
• Modern C++20: Extensive use of concepts, ranges, coroutines, and modules
• Cross-Platform: Works on Linux (g++), macOS (clang++), and Windows (MSVC)
• High Performance: Template metaprogramming and compile-time optimizations
• Type Safety: Comprehensive use of concepts and static assertions
• Async/Await: Native C++20 coroutine support for asynchronous operations

📋 Requirements

System Requirements

• C++ Compiler: GCC 11+, Clang 12+, or MSVC 2019+ with C++20 module support
• CMake: 3.20 or higher
• Standard: C++20 or later

Manual Installation

# Header-only library - copy module files
cp *.ixx /path/to/your/project/modules/

🎯 Quick Start

import from_to;
import runtime;
import countdown;
import asyncgen;
import result;

#include <iostream>
#include <vector>

int main() {
    // Range-based iteration
    for (auto i : from(0).to(10)) {
        std::cout << i << " ";
    }
    
    // Performance measurement
    auto duration = runtime([]() {
        // Your code here
        std::vector<int> data(1000000);
        std::iota(data.begin(), data.end(), 0);
    });
    std::cout << "Execution time: " << duration << " seconds\n";
    
    // Countdown utility
    countdown(3); // Countdown from 3 to 0
    
    return 0;
}

📚 Module Reference

Core Modules

concepts - Type Constraints

Advanced C++20 concepts for type safety and template constraints.

import concepts;

template<arithmetic T>
void process_number(T value) {
    // Only accepts arithmetic types
}

template<real_value_iterator It>
auto compute_average(It first, It last) {
    // Only accepts iterators to floating-point values
}

from_to - Range Generation

Python-style range generation using C++20 ranges.

import from_to;

// Generate ranges
for (auto i : from(5).to(15)) {
    std::cout << i << " "; // 5 6 7 8 9 10 11 12 13 14
}

// Nested loops
for (auto i : from(0).to(3)) {
    for (auto j : from(0).to(3)) {
        std::cout << "(" << i << "," << j << ") ";
    }
}

runtime - Performance Measurement

High-precision execution time measurement.

import runtime;

auto duration = runtime([]() {
    // Expensive operation
    std::this_thread::sleep_for(std::chrono::milliseconds(100));
});

std::cout << "Duration: " << duration << " seconds\n";

result - Error Handling

Rust-inspired error handling without exceptions.

import result;

auto divide(double a, double b) -> result<double, std::string> {
    if (b == 0.0) {
        return error("Division by zero");
    }
    return success(a / b);
}

auto res = divide(10.0, 2.0);
if (res.is_success()) {
    std::cout << "Result: " << res.value() << std::endl;
} else {
    std::cout << "Error: " << res.error() << std::endl;
}

Asynchronous Programming

asyncgen - Async Generators

C++20 coroutine-based asynchronous generators.

import asyncgen;

auto async_range(int start, int end) -> asyncgen<int> {
    for (int i = start; i < end; ++i) {
        co_yield i;
        co_await std::this_thread::sleep_for(std::chrono::milliseconds(100));
    }
}

// Usage
auto gen = async_range(0, 5);
for (auto value : gen) {
    std::cout << value << " ";
}

asynctask - Async Tasks

Task-based asynchronous programming with coroutines.

import asynctask;

auto fetch_data() -> asynctask<std::string> {
    // Simulate async operation
    co_await std::this_thread::sleep_for(std::chrono::seconds(1));
    co_return "Data fetched successfully";
}

auto task = fetch_data();
auto result = task.get(); // "Data fetched successfully"

wait_for - Async Delays

Fluent interface for time-based delays.

import wait_for;

wait_for(2).seconds();
wait_for(500).milliseconds();
wait_for(1).minute();

// Use modules independently
int main() {
    auto duration = runtime([]() {
        for (auto i : from(0).to(1000000)) {
            // Process data
        }
    });
    
    std::cout << "Processing completed in " << duration << " seconds\n";
    return 0;
}
