IACore is a high-performance, battery-included C++20 foundation library designed to eliminate "dependency hell." It bundles essential systems—IPC, Logging, Networking, Compression, and Async Scheduling—into a single, coherent API.

Originally developed as the internal core for IASoft (PVT) LTD., it is now open-source to provide a standardized bedrock for C++ applications.

## ✨ Features

* **🚀 High-Performance IPC:** Shared-Memory Ring Buffers with wait-free SPSC synchronization.
* **🌐 Networking:** Integrated HTTP/HTTPS client (wrapper around `cpp-httplib` with automatic Zlib/Gzip handling).
* **🧵 Async Scheduler:** A job system with high/normal priority queues and work stealing.
* **💾 File I/O:** Memory-mapped file operations and optimized binary stream readers/writers.
* **📦 Compression:** Unified API for Zlib, Gzip, and Zstd.
* **📜 Logging:** Thread-safe, colored console and disk logging.
* **⚡ Modern C++:** Heavily uses C++20 concepts, `std::span`, and `tl::expected` for error handling.

## 🛠️ Integration

IACore is built with CMake. You can include it in your project via `FetchContent` or by adding it as a subdirectory.

Note: On Windows, you must have VCPKG installed and the VCPKG_ROOT environment variable set, for OpenSSL support.

### CMake Example
```cmake
add_subdirectory(IACore)

add_executable(MyApp Main.cpp)
target_link_libraries(MyApp PRIVATE IACore)
```

## 📦 Dependencies
IACore manages its own dependencies via CMake's FetchContent. You do not need to install these manually:

* nlohmann_json & glaze (JSON Parsing)
* cpp-httplib (Networking)
* zlib-ng & zstd (Compression)
* tl-expected (Error Handling)

## 💡 Usage Examples
### 1. IPC (Manager & Node)
IACore provides a manager/node architecture using shared memory.

Manager:

```C++
#include <IACore/IPC.hpp>

// Spawns a child process and connects via Shared Memory
auto nodeID = manager.SpawnNode("MyChildNodeExe");
manager.WaitTillNodeIsOnline(*nodeID);

// Send data with zero-copy overhead
String msg = "Hello Node";
manager.SendPacket(*nodeID, 100, {(PCUINT8)msg.data(), msg.size()});
```

### 2. Async Jobs
```C++

#include <IACore/AsyncOps.hpp>

// Initialize worker threads (hardware_concurrency - 2)
IACore::AsyncOps::InitializeScheduler();

// Schedule a task
IACore::AsyncOps::Schedule *mySchedule = new IACore::AsyncOps::Schedule();

IACore::AsyncOps::ScheduleTask([](auto workerID) {
    printf("Running on worker %d\n", workerID);
}, 0, mySchedule);

// Wait for completion
IACore::AsyncOps::WaitForScheduleCompletion(mySchedule);
```

### 3. HTTP Request
```C++
#include <IACore/HttpClient.hpp>

IACore::HttpClient client("[https://api.example.com](https://api.example.com)");
auto res = client.JsonGet<MyResponseStruct>("/data", {});

if (res) {
    std::cout << "Data: " << res->value << "\n";
} else {
    std::cerr << "Error: " << res.error() << "\n";
}
```
