ToaruOS (とあるOS)

とあるOS (ToaruOS) is a hobby kernel and supporting userspace, built mostly from scratch, in development since December of 2010.

This repository contains the kernel, modules, and core userspace. Some third-party libraries and utilities are required to build a working system.

History

ToaruOS started as a side project at the University of Illinois at Urbana-Champaign. For several months in late 2011 and early 2012, the University's SIGOps chapter managed development efforts focused on building the original compositing GUI. Since then, the project has mostly been a one-man effort with a handful of third party contributions.

Kernel

The Toaru kernel provides a basic Unix-like environment. The kernel uses a hybrid modular architecture, with loadable modules providing most device driver support. The core kernel includes support for Unix pipes and TTYs, a virtual file system, multitasking, ELF binary support, and various core platform features on x86 systems.

Modules provide support for disk drives, ext2 filesystems, serial, keyboards and mice, a /proc filesystem similar to the one found in Linux, as well as an expanding collcetion of other device drivers.

Userspace

ToaruOS's userspace is focused on a rich graphical environment, backed by an in-house compositing window manager. ToaruOS's terminal emulator supports xterm-compatible 256-color modes, as well as Konsole 24-bit color modes and anti-aliased text with basic Unicode support. Several graphical demos are provided, alongside a number of command-line applications. A port of SDL targetting the native graphical environment is also available.

Third-Party Software

The userspace depends on a number of third-party libraries which are outside of the development scope of the project. Additionally, several third-party applications and libraries have been integrated into ToaruOS's core userspace, or otherwise ported to ToaruOS.
