Start with the release
Download the self-hosted compiler, write a first program, and produce a Linux executable without a C++ toolchain.
Build the future of Australis in Hydrogen.
A self-hosted systems language with direct Linux output today and a growing UEFI path toward Australis OS.
Hydrogen, also called Hylang, is a C#-inspired language built around namespaces, classes, and methods. Its released compiler is written in Hydrogen itself. Use it to build Linux-native programs now and to help build the firmware and kernel layers of Australis OS next.
Understand the current scope
Learn the supported language subset and the exact boundary between Linux-native output and the UEFI proof target.
Boot the proof of concept
Compile a PE32+ EFI application, package it with Australis, and boot it in QEMU with OVMF.
See where it is going
Follow the roadmap from firmware services and keyboard input to a command shell, kernel services, and native apps.
Help shape Hydrogen
The current milestone
Section titled “The current milestone”The released compiler runs on Linux x86-64 and directly emits standalone Linux
x86-64 executables. Its uefi-x64 target can also create a bootable UEFI text
console Hello World. This is a real compiler-to-firmware milestone, but not yet a
complete UEFI library or an independent operating-system kernel.
Australis OS and native Australis applications are the primary direction. Linux is the development host today; Windows and macOS compiler ports will follow when they can be properly packaged and validated.
