Typst: Designing for Incrementality (Laurenz Mädje at RustWeek) [video]
Laurenz Mädje discusses Typst, a Rust-based document typesetting system, focusing on its incremental compilation design for fast preview updates, in contrast to LaTeX's full rebuild model.
Background
- Typst is an open-source, Rust-based typesetting system designed as a modern alternative to LaTeX. Unlike LaTeX, which outputs only the final PDF, Typst is built "for incrementality": it can re-render only the parts of a document that changed (e.g., while you type in the editor), making it far faster for iterative editing.
- Laurenz Mädje is a core developer of Typst, presenting at RustWeek 2024.
- The talk focuses on the technical design decisions that enable incremental compilation and rendering—an approach that prioritises low-latency feedback for writers, similar to how modern IDEs handle code.
- RustWeek is a community conference for the Rust programming language, which Typst is written in. The language choice matters because Rust's memory safety and performance allow Typst to handle complex document layout with speed and correctness.
