The example below shows a simple code snippet from the Hugo source highlighted with the `highlight` shortcode. Note that the gohugo.io site is generated with `pygmentsUseClasses=true` (see [Generate Syntax Highlighter CSS](#generate-syntax-highlighter-css)).
* `linenos=inline` turns on line numbers. Note that the `inline` value only has an effect in Pygments.
* `linenos=inline` or `linenos=table` (`table` will give copy-and-paste friendly code blocks) turns on line numbers.
* `hl_lines` lists a set of line numbers or line number ranges to be highlighted. Note that the hyphen range syntax is only supported for Chroma.
* `linenostart=199` starts the line number count from 199.
With that, this:
```
{{</* highlight go "linenos=inline,hl_lines=8 15-17,linenostart=199" */>}}
{{</* highlight go "linenos=table,hl_lines=8 15-17,linenostart=199" */>}}
// ... code
{{</* / highlight */>}}
```
Gives this:
{{< highlight go "linenos=inline,hl_lines=8 15-17,linenostart=199" >}}
{{< highlight go "linenos=table,hl_lines=8 15-17,linenostart=199" >}}
// GetTitleFunc returns a func that can be used to transform a string to
// title case.
