Somadoc Engine

Can a document be compiled as structure rather than a sequence of pixels, so authors see publish-grade results while writing?

Somadoc implements parsing and a document IR in Rust, compiles Markdown and its handwritten LaTeX math into Typst, and hands the result to the Typst typesetting core to produce PDF or per-page SVG in-process.

The boundary matters: Typst is the typesetting core. Somadoc owns parsing, the IR, incremental compilation contexts, block-level source maps and output. It does not depend on Pandoc, a LaTeX distribution or an external CLI. Per-page SVG lets a preview address individual blocks; persistent contexts avoid re-laying-out unchanged content.

The project is in its open-source planning stage: the core crates, license and public boundary are still under review, so this page does not link to a repository. The only publicly verifiable experience is the Lab shell with a mock adapter; the real engine is not attached yet, and the site does not claim to generate PDF online.

Design goals include PDF/per-page SVG, block-level source maps, incremental compilation and CJK typesetting. Each should be accepted against fixed fixtures and reproducible builds once the real engine is attached.
