🍋 lemOS

lemOS is a lightweight, efficient and modular operating system — inspired by science, lemons, and minimalism.
Created originally by Lemonatix and Abgorion, lemOS blends playful aesthetics with a powerful, customizable UNIX-like core.

"From Lemaître to Lemon — the Big Bang of your desktop experience."

Why “lemOS”?

The name is inspired by my username Lemonatix, as well as

Lemaître, henceforth honoring the father of the Big Bang Theory with the OS.

Roadmap

• Minimal bootable system
  • first step boot process (bootloader), probably with assembly
  • as well as compiler (in C after bootloader)
• Lemon shell (lemsh)
• Filesystem and basic I/O
• GUI prototype
• Package manager (lemonpkg?)
• Optional science-themed wallpapers & Easter eggs

How to compile and run files on Windows

Before compiling it is important to be in the right directory, for windows explicitly (with an example)

cd C:\Users\user\myDirectory\lemOS\userland\    

to be sure that the file will be compile in the same folder as the code itself.

First line compiles the file, just replace "file" with the actual file, second line runs the file

g++ file.c -o file.exe
./file.exe

Compile and run with Linux / Mac via Make

Make enables compile, run and clean very easily. In bash lemOS/ you are able to run

make build TARGET=userland/test
make run   TARGET=userland/test
make clean TARGET=userland/test
make run clean # runs and cleans all c files simultaneously

for specific files in folders (e.g. test.c in the userland folder) or just run the same commands without TARGET, to compile, run and clean everything regarding C files in lemOS.

Disclaimer & Coming soon

This is a hobbyist project and is not yet stable. Not recommended for production use (unless you're very brave), since lemOS is in very early development. Build and installation instructions will be published here when the first release is ready.
