Variables

Variables allow you to store and reuse values throughout your document. They are essential for avoiding repetition, creating dynamic content, and building reusable components.

Defining a variable

Use .var {name} {value} to define a variable. The value is a dynamic value, meaning it can be of any type: text, numbers, booleans, or even complex elements like layouts.

.var {name} {Quarkdown}

Accessing a variable

Once defined, you can access a variable by calling it as a parameter-less function:

.var {name} {Quarkdown}

Hello, **.name**!

Reassigning a variable

You can update a variable’s value at any point. There are two equivalent ways to do this:

• .myvar {newvalue}
• .var {myvar} {newvalue}

.var {mynumber} {5}

.mynumber

.mynumber {.mynumber::sum {1}}

.mynumber

Block variables

As mentioned in Syntax of a function call:

A body argument always refers to the last parameter of the signature.

This means a variable’s value can span multiple lines and contain complex block content, not just simple inline values. This is powerful for storing reusable layouts, styled containers, or any structured content.

.var {myrow}
    .row gap:{2cm}
        A

        B

        C

.container background:{teal} padding:{1cm}
    .myrow

Scoped variables

For temporary variables that should only exist within a limited scope, see the .let function. Unlike .var, which creates document-wide variables, .let creates variables that exist only within a lambda block.
