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 Under reconsideration.
• Build: Equivalent to Unix's Make but also package manager in the style of Nix.
• Linker: Builds finalised Dynamic Link Libraries and executables.
• Asm: An Assembler with macros for better integration 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: FAT32 for UEFI compatible boot partitions, something from Linux for primary storage and ISO9660 for optical media support.
• Graphics Driver: Hardware not yet determined.
• Dynamic Loader: Loads PE formatted executables into RAM with any Dynamic Link Libraries they need.

Libraries

• String: Functions for processing and manipulating textual data.
• *Graphical Primitives Libraries: Equivalent of DirectX on Windows. Provides rendering capacities and event driven I/O.
• Widget Library: Classes that graphical applications are typically built from. Written in MIA using the graphical primitives libraries.

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.
• Text-mode Terminal: Designed from first principles, does not need to emulate physical terminals.
• Graphical Terminal: Above but also taking advantage of being run in a graphical environment.
• Drop-down Terminal: A lighter version of the above Graphical Terminal for quickly running commands. Appears when <F12> is pressed with a drop down animation. Equivalent of KDE's Yakuake.
• 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:
• Game data editor: Akin to Godot minus the text editing features.
• Games If this project ever gets that far.
