# About
Much like boost.io this library is a replacement of the standard C/C++ libraries. It provides most features needed when 
designing applications in a cross-platform manner. The goal for this project is for it to be compiled and run on 
anything which means embedded hardware support.

This project does not fully follow the C++ standard.

### Features
- Audio IO/Processing/Manipulation
- Image Processing/Manipulation
- 3D Model & Mesh Processing/Manipulation
- File IO
- Basic File Monitoring
- Console IO
- 2/3/4D Vectors
- 2x2/3x3/4x4 Matrices
- Hardware/Software Level Math Functions
- Smart Pointers
- Threads
- Mutexes
- Semaphores
- CPU information and features at runtime
- HTTP(S) Sockets
- TCP Socket
- UDP Socket
- COM (Serial) IO
- UTF_8/16/32 Character Encoding
- Spotify Integration
- Twitch Integration
- Json Parsing/Writing
- User Friendly HID Input
- Basic Garbage Collector
- Linked List
- Array
- Vector
- Asynchronous Task System
- URI Parsing

### Supported Architectures
- AMD64
- AARCH64

### Supported Operating Systems
- Windows
- Linux

# Compiling

## Prerequisites
### Linux
- **Arch Linux**: `sudo pacman -S gcc nasm cmake alsa-lib libxcb xcb-util-cursor`
- **Debian Linux**: `sudo apt install gcc nasm cmake libasound2-dev libxcb1-dev libxcb-xinput-dev libxcb-cursor-dev`

For building on the Raspberry Pi instead of the Netwide Assembler (NASM), GCC's Assembler is used.

### Windows
- [Visual Studio Community](https://visualstudio.microsoft.com/vs/community/)
- [Netwide Assembler](https://www.nasm.us/)
- [CMake](https://cmake.org/)
- [vcpkg](https://learn.microsoft.com/en-us/vcpkg/get_started/get-started?pivots=shell-cmd)

## Building
### Linux
1. `cmake -DCMAKE_BUILD_TYPE=Release -DLINUX_WINDOW_SYSTEM:STRING=XCB /path/to/source`
2. `cmake --build /path/to/build --config Release`

The `LINUX_WINDOW_SYSTEM` variable in the first step can be either `XCB` for the X Window System or `Wayland` for the 
Wayland Window System. Wayland support is currently not fully supported yet, use only `XCB`.

### Windows
1. `cmake -A x64 -DCMAKE_BUILD_TYPE=Release --preset=default .`
2. `cmake --build build --config Release`

## Installing
### Linux
`sudo cmake --install . --prefix /usr/local`

### Windows
`cmake --install . --prefix "C:/Program Files/EHS"`

This will require the terminal to be running in administrator mode.

# Simple Example
```cpp
#include <ehs/EHS.h>
#include <ehs/io/Console.h>

ehs::Int_32 Main(ehs::Str_8* appName, ehs::Str_8* appVerId, ehs::Version* appVer)
{
	// Simple identifying meta-data for the logger.
	*appName = "Simple Example App"; // The application's name
	*appVerId = "Release"; // The app's version prefix; i.e. Alpha, Beta or Release as an example.
	*appVer = {1, 0, 0}; // The app's version major, minor and patch number.
	
	ehs::Console::Write_8("How old are you?"); // Write to the console in UTF_8 character encoding.
	
	ehs::Str_8 response = ehs::Console::Read_8(); // Read from the console in UTF_8 character encoding.
	
	if (!response.IsNum())
    {
		ehs::Console::Clear(); // Clear the console's buffer.
		return Main(appName, appVerId, appVer); // Repeat process if given response is not a number.
    }
	
	ehs::UInt_8 age = response.ToDecimal<ehs::UInt_8>(); // Converts the string number into a number based primitive.
	
	ehs::Console::Write("Your age is " + ehs::Str_8::FromNum(age) + "."); // Write the console with the age converted back to string.

    return 0;
}
```
