🪐 Markdown with superpowers.

Quarkdown is a Markdown parser and renderer that extends the capabilities of Markdown, bringing support for functions and 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.

.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.

Check the wiki to learn more about the language and its features.

Targets

• HTML
  • ✅ Plain output (default)
  • ✅ Slides (via reveal.js)
  • ✅ Paged (books, articles) (via paged.js)
  • Quarkdown's HTML is PDF-ready: check the wiki to learn how to convert an artifact to PDF.

The desired document type can be set by calling the .doctype function within the Markdown source itself:

• .doctype {slides}
• .doctype {paged}

Installation

Download quarkdown.zip from the releases page or build it yourself with gradlew distZip, and unzip it.
If you'd rather keep it minimal, gradlew build produces only the JAR file.

The bin directory contains the executable scripts. Optionally, add it to your PATH to access Quarkdown more easily.

Java 17 or higher is required.

Getting started

Running the program with no command-line arguments runs it in REPL mode. This is great for familiarizing yourself with Quarkdown, but it's probably not what you're looking for.

Running quarkdown file.qmd will compile the given file, save the output to file and log its content.

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?

Options

• -o <dir> or --output <dir>: sets the directory of the output files. If unset, defaults to ./output.

• --pretty: produces pretty output code. This is useful for debugging or to read the output code more easily, but it should be disabled in production as the results might be visually affected.

• --clean: deletes the content of the output directory before producing new files. Destructive operation.

• --strict: forces the program to exit if an error occurs. When not in strict mode, errors are shown as boxes in the document.

• --no-media-storage: turns the media storage system off. (?)

• -Dloglevel=<level> (JVM property): sets the log level. If set to warning or higher, the output content is not printed out.

Themes

Quarkdown comes with a set of themes that can give a unique look to your document.

• How to apply a theme?

Theme contributions are welcome!
Please make sure they work well with all the three document types before submitting.

Scripting

Iterative Fibonacci

.var {t1} {0}
.var {t2} {1}

.table
    .foreach {0..8}
        n:
        | $ F_{.n} $ |
        |:----------:|
        |    .t1     |
        .var {tmp} {.sum {.t1} {.t2}}
        .var {t1} {.t2}
        .var {t2} {.tmp}

$F_0$	$F_1$	$F_2$	$F_3$	$F_4$	$F_5$	$F_6$	$F_7$	$F_8$
0	1	1	2	3	5	8	13	21

Recursive Fibonacci

The recursive approach is significantly slower than the iterative one.

.function {fib}
    n:
    .if { .islower {.n} than:{2} }
        .n
    .ifnot { .islower {.n} than:{2} }
        .sum {
            .fib { .subtract {.n} {1} }
        } {
            .fib { .subtract {.n} {2} }
        }
  
.table
    .foreach {0..8}
        | $ F_{.1} $ |
        |:----------:|
        | .fib {.1}  |

$F_0$	$F_1$	$F_2$	$F_3$	$F_4$	$F_5$	$F_6$	$F_7$	$F_8$
0	1	1	2	3	5	8	13	21

Concept

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.
