> [!WARNING]

> This branch is for historical purposes only. It is used as a monument to the year 2022, and may be used as a "nostalgia kit" to build older SalernOS versions from that year. Note that updates were made to this repository during the 2023 "hellow" rewrite of the kernel, so the Docker/Make files may not be suitable to build source code from 2022. A fourth, and hopefully decent, rewrite will soon commence.



# SalernOS

SalernOS is a small, work-in-progress, one-man project to learn Operating System development by building one from scratch.





    

    
 This is a demo of what a future SalernOS Desktop may look like 





## Project Structure

Every component of SalernOS resides in its own repository, all respositories are hosted on this [GitHub account](https://github.com/Alessandro-Salerno).

The structure of individual SalernOS Components is not standardized.



## Goals

SalernOS is a toy Operating System. "toy" as in a piece of software that is written for non-commercial and non-professional use, but is rather intended for entertainment and improvement of programming skills. That said, I would like to achieve some milestones. These are, in no particular order:

* Establishing a framework for Hobbist Operating Systems - See [OpenBIT](https://github.com/OpenBitt)

* Building an alternative userland - Just for fun

* Bringing SalernOS to other processor platforms such as [AARCH64](https://en.wikipedia.org/wiki/AArch64) and [RISC-V](https://en.wikipedia.org/wiki/RISC-V)

* Bringing SalernOS to a self-designed processor architecture and running it in emulation or physical hardware (If possible)

* Porting the [GNU System](https://www.gnu.org/home.en.html) to SalernOS - Building GNU/SalernOS

* Building a Graphics Stack (GPU Drivers, [X11](https://en.wikipedia.org/wiki/X_Window_System)/[Wayland](https://en.wikipedia.org/wiki/Wayland_(display_server_protocol)) Server, Window Manager, OpenGL Implementation)

* Overall, making a farely simple, yet usable [FOSS](https://en.wikipedia.org/wiki/Free_and_open-source_software) graphical Operating System



## Right now

Currently, most of the work on SalernOS is concentrated on the [SalernOS-Kernel](https://github.com/Alessandro-Salerno/SalernOS-Kernel), and on building the [OpenBIT System Specification](https://github.com/OpenBitt/OpenBit-Specs/blob/main/OpenBIT-System-Specification.md). Despite all the effort, progress is slow, the SalernOS-Kernel is not yet ready for prime time, but I'm determined to get a somewhat usable version out by the end of 2022.



## The future

As shown in the picture, the short to medium term goal of SalernOS is to build a simple OS. Allthough the project is not fully outlined, the idea is to use a distribution model similar to that of [Linux](https://en.wikipedia.org/wiki/Linux) and other Free Operating SYstems. The SalernOS Standard Distribution would be the polished and working distro using GNU, while the SalernOS Experimental Distribution would be the 100% self-built software distribution. Standard Distribution components may include:

* [GCC - The GNU Compiler Collection](https://en.wikipedia.org/wiki/GNU_Compiler_Collection)

* [BASH](https://en.wikipedia.org/wiki/Bash_(Unix_shell))

* [Binutils - The GNU Linker](https://en.wikipedia.org/wiki/GNU_Binutils)

* [GNU Coreutils](https://en.wikipedia.org/wiki/GNU_Core_Utilities)

* X11/Wayland Server

* SalernOS MultiShell Window Manager

* Some random package manager



While the SalernOS Experimental Distribution may include:

* The SalernOS C Compiler

* The SalernOS Assembler

* The SalernOS Linker

* The OpenBit Shell

* X11/Wayland Server

* SalernOS MultiShell Window Manager

* SalernOS Core Utilities

* SGet - The SalernOS Package Manager
