{{value:foo}}

The {{value:foo}} substitution parameter evaluates to the value of the header referenced by its rvalue.

For example, this node has a Foo header defined like this:

Foo: Foo Header Value

If we include the {{value:foo}} parameter on the page, it will be replaced with the value of the header when the page is rendered.

This is the value of the Foo header: Foo Header Value

HTML Escaping

When the HTML pages are rendered, the value of the {{value:foo}} parameter will be HTML escaped.

There is also another variant of this parameter, {{value-unescaped:foo}}, which works identically, except without the HTML escaping step.

Naming Convention

By convention, headers are set using Mixed-Case-With-Dashes. However, when they are referenced in substitution parameters, they are referenced in lowercase.

For example, a node might set a header and reference the same header directly like this:

Title: Some Example Node
Foo-Bar-Baz-Quux: Some Value

Here is the value of Foo-Bar-Baz-Quux: {{value:foo-bar-baz-quux}}

The example above would render in the generated page as:

Here is the value of Foo-Bar-Baz-Quux: Some Value
