This function is only useful within a code block render hook.

Given the context passed into a code block render hook, transform.HighlightCodeBlock returns a HighlightResult object with two methods.

.Wrapped
(template.HTML) Returns highlighted code wrapped in <div>, <pre>, and <code> elements. This is identical to the value returned by the transform.Highlight function.
.Inner
(template.HTML) Returns highlighted code without any wrapping elements, allowing you to create your own wrapper.
{{ $result := transform.HighlightCodeBlock . }}
{{ $result.Wrapped }}

To override the default highlighting options:

{{ $options := merge .Options (dict "linenos" true) }}
{{ $result := transform.HighlightCodeBlock . $options }}
{{ $result.Wrapped }}
