undo-ssg

:toc: :toc-title: Table of Contents :icons: font

Reversible static site generation in the Arrow language. "undo" — The trajectory of reversible logic. A generator that moves forward to build and backwards to un-build.

Who Is This For?

• Reversible computing researchers seeking zero-entropy site synthesis.

• Systems Engineers targeting ASICs where thermal efficiency is the primary constraint.

• Verification Purists requiring isomorphic mappings between source and output.

Why undo-ssg?

Information Preservation

Unlike traditional SSGs that "lose" source data during rendering, undo-ssg is built in a reversible language. Every build step is an isomorphism; the HTML output contains the mathematical potential to reconstruct the source markdown exactly.

Zero-Entropy Logic

Reversible operations avoid the energy cost of erasing information. undo-ssg is designed for high-efficiency hardware and Edge tech deployments where heat dissipation is a failure state.

Deterministic Inversion

"Un-call" a procedure to revert a site build to its previous state with mathematical certainty. No more partial state corruption during failed deployments.

Quick Start

# Bootstrap the Arrow/Janus environment via asdf
just setup

# Build the site forward
just build-forward

# Reverse the build to verify source integrity
just build-backward

Features

• Isomorphic Synthesis - 1:1 mapping between source and rendered state.

• Thermodynamic Efficiency - Near-zero energy dissipation for Edge hardware.

• Podman-First - Isolated, reversible build environments.

• Accessibility - Integrated support for BSL, GSL, ASL, and Makaton.

Requirements

• Arrow/Janus Interpreter

• Just (Orchestrator)

• Podman (Container Engine)
