Template

@defineDirective

Declares a template — a node shape written once and stamped out wherever its name is used. The implicit attribute `node` names the type being declared, written in the head (`@define:card`); the attribute group declares the template’s own parameters with their defaults, and `{{param}}` splices each parameter verbatim into the body. A template may use other templates, but circular expansion is a compile error.

Attributes

nodeRequiredImplicit

The name of the type being declared, written in the head: @define:card. It cannot also be a template parameter.The head shorthand supplies it: @define:value

Allowed content

Body { }The template — the Chalk that replaces each use, with {{param}} splices

Examples

@define:swatch{
    square(x: 0; y: 0; size: 1; colour: {{colour}})
}(
    colour: blue
)
