I started this project back in 2015, to translate the TeX original specification into an easily parsed format (s-doc), and to create an HTML rendering of that format as a proof of concept.The project is homed here: https://codeberg.org/dlowe/metaspectre/Differences from the Hyperspec (from the README): - Most importantly, it is free to modify and distribute.
- The original TeX is very hard to parse and use for things other than
generating a printed copy. The Hyperspec is an HTML rendering which
can be parsed as HTML, but loses a lot of information. The Metaspec
has an easily parsed intermediate form that can be used for all kinds
of purposes, like converting into lookups.
- Math equations are rendered using MathML.
- Includes the acknowledgements and appendix sections.
- Uses progressively enhanced Javascript to provide search and
light/dark theme switching.
- Incorporates over 145 patches for content, using corrections
accumulated over the years, and documented in the errata page.
- Includes TeX comments, which can contain interesting historical data.
- Includes links and identifiers to bibliographical references.
Show HN: Metaspec: The DpANS3R Common Lisp Spec in S-Expr and HTML Format

AI Executive Synthesis
A free-to-modify and distribute alternative to Hyperspec, providing an easily parsed intermediate form, MathML rendering, accumulated corrections, and historical TeX comments, enhancing the utility of the Common Lisp specification.
Metaspec addresses a niche but significant pain point within the Common Lisp community: the difficulty of programmatically interacting with the official language specification. By translating the TeX original into an easily parsed S-Expr format and providing an HTML rendering, it offers a superior alternative to the existing Hyperspec. Key differentiators include its modifiability, preservation of information lost in HTML-only parsing, MathML support, and incorporation of 145+ content corrections. This project enhances the accessibility and utility of a foundational technical document, enabling new tooling and analysis previously impractical. While not a direct B2B SaaS play, it represents a critical infrastructure improvement for developers and tool builders within its ecosystem, potentially fostering innovation by making core documentation more machine-readable and maintainable.
