"neither master nor slave to neither god nor man."

infernal-init is a high-performance shell initiation banner written in Nim. Unlike traditional "fetch" tools, it is designed as the graphical manifestation of a new terminal session, providing immediate branding, high-impact ASCII art, and essential system telemetry.

• Dissected ASCII Architecture: Dynamically injects branding banners into complex ASCII art blocks.
• TrueColor Support: Utilizes specific TrueColor palettes extracted from custom artwork.
• Lightweight & Fast: Compiled Nim binary with zero runtime dependencies.
• Nix-Native: Fully Flake-enabled for seamless integration into NixOS configurations.
• Robust Telemetry: Graceful fallbacks for system info (OS, Kernel, Uptime, Shell).

Run it immediately without installing:

nix run github:lowcache/infernal-init

1. Add it to your flake.nix inputs:

inputs.infernal-init.url = "github:lowcache/infernal-init";

1. Add the package to your home-manager or system packages:

environment.systemPackages = [
  inputs.infernal-init.packages.${system}.default
];

1. Trigger it in your shell configuration (e.g., fish):

if status is-interactive
    infernalinit
end

The tool embeds assets at compile-time for maximum speed. To customize the ASCII art or tagline, modify assets/tbann and src/infernalinit.nim respectively, then rebuild the derivation.
