Truncated

You can define a summary manually, in front matter, or automatically. A manual summary takes precedence over a front matter summary, and a front matter summary takes precedence over an automatic summary.

The Truncated method returns true if the content length exceeds the summary length. This is useful for conditionally rendering a “read more” link:

{{ range .Pages }}
  <h2><a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a></h2>
  {{ .Summary }}
  {{ if .Truncated }}
    <a href="{{ .RelPermalink }}">Read more...</a>
  {{ end }}
{{ end }}

To render the content in a named scope, call Markup.Render.Summary.Truncated on a Page object.
