Given a site configuration that contains this menu entry:

{{< code-toggle file="hugo" >}} menu.main name = "IRC" url = "irc://irc.freenode.net/#golang" {{< /code-toggle >}}

Attempting to use the url value directly in an attribute:

{{ range site.Menus.main }}
  <a href="{{ .URL }}">{{ .Name }}</a>
{{ end }}

Will produce:

<a href="#ZgotmplZ">IRC</a>

ZgotmplZ is a special value, inserted by Go's template/html package, that indicates that unsafe content reached a CSS or URL context.

To override the safety check, use the safeHTMLAttr function:

{{ range site.Menus.main }}
  <a {{ printf "href=%q" .URL | safeHTMLAttr }}>{{ .Name }}</a>
{{ end }}
