Kaelum

Kaelum is a high-performance, GPU-accelerated terminal emulator engineered for absolute efficiency, surgical system integration, and zenith-level aesthetics.

Designed from the ground up to be the definitive terminal for the Fish shell, Kaelum bypasses traditional bottlenecks to provide a zero-latency interface between the user and the machine.

🌌 Philosophy

Kaelum is built on three pillars:

1. Absolute Performance: Utilizing io_uring for I/O and Vulkan 1.3 for rendering to ensure that the hardware is the only limiting factor.
2. Surgical Precision: Low-level integration with the Linux kernel and Wayland protocol, avoiding bloated abstractions.
3. Zenith Design: A visual experience that mirrors the elegance and fluidity of the Veridian Zenith identity.

🛠 Tech Stack

• Language: C++26 (Clang++ / mold)
• I/O: io_uring
• Graphics: Vulkan 1.3
• Windowing: Native Wayland
• Typography: FreeType + HarfBuzz
• Build System: CMake + Ninja

🏗 Architecture

• Loom: The asynchronous I/O weaver handling PTY communication via io_uring.
• Nexus: The high-speed ANSI/VT state machine for sequence parsing.
• Sigil: The GPU-resident glyph renderer for flicker-free, high-refresh-rate output.
• Aura: The aesthetic layer managing shaders, blur, and fluid animations.
