Welcome to OfflineOS

Offline OS is my project to create a self-sufficient, desktop Operating System starting from the programming languages up.

At present a bootstrap implementation of the systems programming language is being developed.

Due to the extraordinarily wide scope of this project it is divided into a series of sub-projects and sub-sub-projects:

Toolchain

A set of complementary programming languages and related tools. Note that most of these will have to be written twice, the first time for cross-compiling from Linux.

• Mac: Equivalent to C's pre-processor but more pervasive through the toolchain.
• Build: Equivalent to Unix's Make but also package manager in the style of Nix.
• Linker: Builds finalised Dynamic Link Libraries and executables.
• X64asm: An Assembler with Mac macros to better integrate with compiled languages.
• OTIL: The One True Implementation Language. A procedural language for systems programming.
• MIA: Mia Is Awesome. An Object-Functional language for application programming.
• ExLang: Dynamically typed and JIT'ed language for writing application plugins.
• Libraries: Written in OTIL and MIA.

System Space

• Boot Loader: UEFI based, might be built directly into the Captain.
• Captain: The operating system kernel. Few design decisions have been made yet.
• File Systems
• Dynamic Loader: Loads PE formatted executables into RAM with any Dynamic Link Libraries they need.

Libraries

• Widget Library: Classes typical graphical applications are built from. Written in MIA.

Applications

As OfflineOS is meant to be self-sufficient it needs a bare minimum of every application needed to improve it.

• Command Interpreter
• Superitor: A Vim-like editor that supports multi-language source files and extensions.
• Terminal: Designed from first principles, does not need to emulate physical terminals
• File Manager Focus on loading files on and off USB devices
• Configuration Centre
• Reader: Supports EPub, PDF and HTML via libraries
• Pixel Editor
• Vector Editor
• Image Viewer
• 3D Animation Suit
• Video Player Supports file collection and DVD
• Music Player Supports file collection and CD's. Heavily stylised, non-standard UI. Animations.
• Music Composition Program
• Audio Editor
• Video Editor
• CD Burner / Ripper
• Games If this project ever gets that far.
