Quarkdown is a modern Markdown-based typesetting system designed for versatility. It allows a single project to compile seamlessly into a print-ready book, academic paper, knowledge base, or interactive presentation. All through an incredibly powerful Turing-complete extension of Markdown, ensuring your ideas flow automatically into paper.

Born as an extension of CommonMark and GFM, the Quarkdown Flavor brings functions to Markdown, along with many other syntax extensions.

This is a function call:

.somefunction {arg1} {arg2}
    Body argument

Possibilities are unlimited thanks to an ever-expanding standard library, which offers layout builders, I/O, math, conditional statements and loops.

Not enough? You can still define your own functions and variables, all within Markdown. You can even create awesome libraries for everyone to use.

.function {greet}
    to from:
    **Hello, .to** from .from!

.greet {world} from:{iamgio}

Result: Hello, world from iamgio!

This out-of-the-box scripting support opens doors to complex and dynamic content that would be otherwise impossible to achieve with vanilla Markdown.

Combined with live preview, ⚡ fast compilation speed and great editor support, Quarkdown simply gets the work done, whether it's an academic paper, book, knowledge base or interactive presentation.

In a nutshell, Quarkdown is...

• Familiar: built on the well-known Markdown syntax, for a flat learning curve
• Elegant: produces output that matches the quality of industry-leading tools
• Agent-friendly: comes with a built-in skill for idiomatic fluency of your coding agents (read the eval)
• Customizable: full control over document layout, aesthetics, and properties
• Secure by default: a restrictive permission system limits access to system resources
• Versatile: a single source compiles to multiple targets
• Reactive: low-latency live previews for rapid iteration. The official wiki (100+ subdocuments) compiles in ~2 seconds
• Reusable: repeated content can be turned into one-line function calls
• Easily deployable: set a CD workflow up in under 3 minutes (example)

Root privileges let the script install Quarkdown into /opt/quarkdown and its wrapper script into /usr/local/bin/quarkdown.
The browser required for PDF export is installed automatically.

New user? You'll find everything you need in the Quickstart guide to bring your first document to life!

quarkdown create [directory] will launch the prompt-based project wizard, making it quicker than ever to set up a new Quarkdown project, with all metadata and initial content already present.

Running quarkdown c file.qd will compile the given file and save the output to file.

If the project is composed by multiple source files, the target file must be the root one, i.e. the one that includes the other files.

• How to include other files?

If you would like to familiarize yourself with Quarkdown instead, quarkdown repl lets you play with an interactive REPL mode.

The most commonly used options are:

• -p or --preview: enables automatic content reloading after compiling.

• -w or --watch: recompiles the source every time a file from the source directory is changed.

• --pdf: produces a PDF file. Learn more in the wiki's PDF export page.

For the full list of options, check out the CLI options wiki page.

Mock, written in Quarkdown, is a comprehensive collection of visual elements offered by the language, making it ideal for exploring and understanding its key features — all while playing and experimenting hands-on with a concrete outcome in the form of pages or slides.

• The document's source files are available in the mock directory, and can be compiled via quarkdown c mock/main.qd -p.
• The PDF artifacts generated for all possible theme combinations are available and can be viewed in the generated repo.

The logo resembles the original Markdown icon, with focus on Quarkdown's completeness, richness of features and customization options, emphasized by the revolving arrow all around the sphere.

What could be mistaken for a planet is actually a quark or, more specifically, a down quark, an elementary particle that is a major constituent of matter: they give life to every complex structure we know of, while also being one of the lightest objects in existence.

This is, indeed, the concept Quarkdown is built upon.
