The profan Operating System is an independent OS developed from scratch.
It is characterized by its ring0-only preemptive modular multitasking
minimalist kernel and colorful-looking command line-based user interface.
[Test it from your browser](https://elydre.github.io/profan)
without installing anything.

You can find a progress roadmap in [github projet](https://github.com/users/elydre/projects/7),
a [monthly updates](https://github.com/elydre/profanOS/discussions/categories/retrospective) and
the [wiki](https://github.com/elydre/profanOS/wiki) for documentation.

## Setup

> [!NOTE]
> Compilation is guaranteed only on linux but
> it is also possible in windows with virtualization
> solutions like wsl (on windows 11) or hyperV.

### Install dependencies

```bash
# Debian based
sudo apt update
sudo apt install -y make python3 gcc g++ nasm qemu-system-i386 \
                    grub-common xorriso grub-pc-bin mtools

# Arch based
sudo pacman -Syu
sudo pacman -S      make python gcc nasm qemu-full xorriso \
                    grub-common mtools
```

### Compile & Run

```bash
# Compile and run
make run

# Show all commands
make help
```

Each time the disk is modified you must force its reconstruction with `make disk`.
The main ports (more information in the [ports](#Major ports - Addons) section) are not included
in the repo source code but are easily downloadable with `make addons disk`.

### Automated build

You can download the build images from the [latest release](https://github.com/elydre/profanOS/releases/tag/latest)
or the repo [profanOS-build](https://github.com/esolangs/profanOS-build).

```bash
# Run the iso image in qemu
qemu-system-i386 -cdrom profanOS.iso

# With KVM acceleration
qemu-system-i386 -cdrom profanOS.iso -enable-kvm
```

profanOS can also be tested online with two clicks with the [v86 copy](https://github.com/copy/v86)
emulator [here](https://elydre.github.io/profan).

## First look

When starting profanOS, you will be greeted by the [Olivine](https://github.com/elydre/profanOS/wiki/olivine) shell, a language similar to bash.
You can then run the `help` command to see a list of useful commands.

> [!TIP]
> To switch the keyboard layout use the `kb <layout>` command, such as `kb qwerty`.

## The kernel

### Overview

The **profanOS kernel** is the core of the operating system. It is extremely minimalist and
provides only the essential features required to run a multitasking OS. Everything
non-essential is kept outside of the kernel and implemented as modules.

**Main features**:

- multiboot support
- 32 bits protected mode
- custom modular filesystem
- preemptive multitasking
- virtual memory management
- syscalls with interrupts
- ELF modules loading

### Modules

Modules extend the kernel with additional functionality, they can be hot-loaded and
have access to all kernel functions. Typical modules provide drivers, UNIX compatibility
layers, or low-level libraries.

**Main modules**:

- unix file descriptors interface
- ATA and AHCI disk driver
- profan filesystem extansion
- intel HDA audio driver
- panda terminal emulator

## The userspace

### Programing languages

The kernel and userspace are developed mainly in C. The Olivine Shell (see the
[language documentation](https://github.com/elydre/profanOS/wiki/olivine)) is the main shell language.
You can also use python3, posix-sh, lua, perl, sulfur, and C languages to create your
own programs.

If you prefer a bash like rather than Olivine, you can use the `dash` port which is
POSIX compliant and often used as `/bin/sh` in linux systems.

### Major ports - Addons

- [python](https://www.python.org/) Python 3.11 interpreter
- [dash](https://github.com/elydre/dash-profan) POSIX compliant shell
- [tcc](https://bellard.org/tcc/) Small and fast C compiler
- [GNU make](https://www.gnu.org/software/make/) Makefile interpreter
- [doom](https://github.com/ozkl/doomgeneric) Raycasting first person shooter

All the ports are available with the command `make addons`.
A lot of programs are compiled from [this repo](https://github.com/elydre/libatron),
you can also find a list of stuff tested in profanOS
[here](https://github.com/stars/elydre/lists/compile-in-profan).

### Libraries

Libraries are loaded from file system and are dynamically linked to executables using
`deluge` (profan dynamic linker).

Here is a list of the main libraries and kernel modules:

- **libc** - standard C library
- **libpf** - extra stuff like [libtsi](https://github.com/elydre/profanOS/wiki/lib_tsi)
- **libm** - math library *(port)*
- **libSDL2** - Simple DirectMedia Layer 2 *(port)*

Find all the libraries available on the [wiki](https://github.com/elydre/profanOS/wiki/Dev-Links).

## Real-Hardware

profanOS works on pc with legacy bios but not with uefi. However profanOS
can work on recent pc by activating bios compatibility.

To install profanOS on a USB key or an internal disk, it is possible to use
the installation script `tools/install.sh` or any other image flasher.

> [!WARNING]
> Installing an OS on a real machine can be risky and
> must be done with knowledge of the possible risks!

### Install on USB key

- Download ISO or build it in linux
- Flash the ISO on the USB key with `dd` or any other image flasher
- Activate the legacy bios in the bios settings (if not already done)
- Boot on the USB key from the bios boot menu
- select the graphical mode

### Install on internal disk

This method is dangerous and will cause the complete erasure of your machine's disk.
Please make a backup of your data and be sure of what you are doing.

- Activate the legacy bios in the bios settings (if not already done)
- Boot on a live linux
- Download ISO or build it in linux
- Flash the ISO with `tools/install.sh` or any other image flasher

```sh
# replace sdX with the disk to flash
sudo sh install.sh /dev/sdX profanOS.iso
```

- Reboot on the internal disk
