Quarkdown

Quarkdown is an open‑source typesetting system that extends Markdown with LaTeX‑like capabilities, allowing authors to produce research papers, books, presentations, static websites, and knowledge‑base wikis from a single source format. It provides a set of document‑type directives (e.g., paged, plain, docs, slides) that configure layout and output for different media, and includes extensions for embedding images, equations, and custom scripting blocks. The tool emphasizes a fast, reactive preview that recompiles instantly as the user types, supporting a smooth writing workflow without extensive boilerplate.

Target users are developers, researchers, educators, and technical writers who want a lightweight markup language but need the expressive power of LaTeX for complex documents. By handling both content authoring and final typesetting, Quarkdown aims to replace separate tools for papers, wikis, and slide decks with a unified pipeline.

Its distinctive features include a live preview engine, a small set of declarative directives that switch between document modes, and a scripting syntax that enables reusable components and custom formatting, all distributed under an open‑source license.
