ToaruOS (also known as ToAruOS or とあるOS; 'toaru' is Japanese roughly equivalent to 'a certain') is a hobby operating system[1] and kernel developed largely independently (notably contrary to most modern OSes, which are based on existing source code) by Kevin Lange. Despite a 1.0 version being released, Lange has stated that it is still 'incomplete', and may not be 'suitable for any purpose you might have for an operating system'.[2][3] It is released under the permissive UIUC License,[4] and supports 32-bit computer hardware without SMP.[5]

Design and features

ToaruOS is programmed in C,[6] and uses the Cairo graphics library.[7] It has support for GCC, Python, and Simple DirectMedia Layer as well as many open-source utilities - including Vim.[5] A package manager and basic window switcher[7] are also included.

The kernel is a 'basic Unix-like environment'. It has a hybrid architecture, with internal and external device support being delegated to modules. Several filesystems are supported via this system, including ext2 and ISO 9660.[8] Networking support is included, but is limited to simple IPv4 functionality.[3] The userspace also has a window manager, Yutani (named after the Wayland-Yutani Corporation from the Alien franchise, and as a reference to the Wayland Display Server for Linux), with input support.[7] It stores windows as shared memory regions with 32-bit colour, and uses pipes to communicate to other parts of the OS. Unusually, windows also support a rotation feature.

History

Development was started by creator Kevin Lange in December 2010;[1] it initially was supported by the University of Illinois at Urbana–Champaign, but after the beginning of 2012, it largely shifted to being mostly done by Lange.[9] Initially, it was based on tutorials for x86 kernels.[10] The operating system was named after the A Certain Scientific Railgun series of manga, but Lange stated it also mirrors generic naming of other hobby OSes. A GUI was added with a window manager in 2012,[7] this was replaced with a more advanced version in 2014.

The initial official release, version 1.0, was released at the end of January.[5] This marked the first stable release, but Lange stated it was still 'a work in development with so much work left to be done'.[2] This was superseded by versions 1.0.1 and 1.0.2, which added audio improvements and fixed bugs.[5]
