Public Business Machines is an open software organization focused on building accessible, developer-friendly tools for document authoring, scripting, and print-production workflows.

The Billetscript Editor is a document scripting and layout editor designed for composing structured documents — including billets, notices, certificates, and formal correspondence — with precision formatting and print-ready output.

Key capabilities of the Billetscript Editor include:

• Script-based document authoring — Define document content and layout through a concise scripting syntax, enabling repeatable and version-controlled document production.
• Rich text and layout control — Fine-grained control over typography, margins, and page geometry to meet formal document standards.
• Print-production workflows — Export documents directly to print-ready formats suitable for professional and commercial production.
• Blue Electroplate integration — Built-in support for the Blue Electroplate rendering pipeline (see below).

Blue Electroplate (Blue Electroplate v1.cs) is the core rendering and output component of the Billetscript Editor. Inspired by the historical electroplate printing process — where a high-fidelity metal plate is formed from a composed document to enable precise, repeatable reproduction — Blue Electroplate translates a Billetscript document into a finalized, print-quality output.

• Document rendering engine — Converts Billetscript source documents into structured, fully laid-out output representations ready for display or export.
• High-fidelity reproduction — Preserves precise typographic and spatial properties of the original composition during rendering, ensuring output matches the authored intent.
• Electroplate pass pipeline — Executes a multi-stage processing pipeline (the "electroplate pass") that resolves references, applies styles, calculates layout geometry, and produces the final document plate.
• Format export — Supports exporting the rendered plate to multiple output formats, including print-ready PDFs and structured data representations.
• Error and validation reporting — Provides detailed validation feedback during the electroplate pass, highlighting document structure issues before output is committed.
• Extensible rendering hooks — Exposes hooks at each stage of the pipeline, allowing downstream tools and integrations to inspect or modify the document plate during rendering.

Blue Electroplate serves as the bridge between human-authored Billetscript documents and their final physical or digital output. It encapsulates all logic required to take a raw script and produce a verified, reproducible document, making it the foundation of the Billetscript Editor's print-production capability.
