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.

Compiling/Building/Installing

Linux

Prerequisites

• 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.

Building

cmake -DCMAKE_BUILD_TYPE=Release -DLINUX_WINDOW_SYSTEM:STRING=XCB /path/to/source

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.

Compiling

cmake --build /path/to/build --config Release

Installing

sudo cmake --install /path/to/build --prefix /usr/local

Windows

Prerequisites

• Visual Studio Community
• Netwide Assembler
• CMake
• vcpkg

Building

cmake -A x64 -DCMAKE_BUILD_TYPE=Release --preset=default /path/to/source

Compiling

cmake --build /path/to/build --config Release

Installing

cmake --install /path/to/build --prefix "C:/Program Files/EHS"

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

Simple Example

#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;
