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.
|
|
|
|
|
|
```go-html-template
|
|
{{ $result := transform.HighlightCodeBlock . }}
|
|
{{ $result.Wrapped }}
|
|
```
|
|
|
|
To override the default [highlighting options]:
|
|
|
|
```go-html-template
|
|
{{ $options := merge .Options (dict "linenos" true) }}
|
|
{{ $result := transform.HighlightCodeBlock . $options }}
|
|
{{ $result.Wrapped }}
|
|
```
|
|
|
|
[highlighting options]: /functions/transform/highlight/#options
