A variable is accessed by referencing the variable name. nfiguration (for sitewide values), or through the meta data of each specific piece of content. You can define any values of any type (supported by your front matter/config format) and use them however you want to inside of your templates.

A unique characteristic of go templates is they are content aware. Variables and content will be sanitized depending on the context of where they are used. More details can be found in the go docs.

Go template ship with a few functions which provide basic functionality. The go template system also provides a mechanism for applications to extend the available functions with their own. Hugo template functions provide some additional functionality we believe are useful for building websites. Functions are called by using their name followed by the required parameters separated by spaces. Template functions cannot be added without recompiling hugo.

Example:

params:
  CopyrightHTML: "Copyright © 2013 John Doe. All Rights Reserved."
  TwitterUser: "spf13"
  SidebarRecentLimit: 5

Within a footer layout, you might then declare a <footer> which is only provided if the CopyrightHTML parameter is provided, and if it is given, you would declare it to be HTML-safe, so that the HTML entity is not escaped again. This would let you easily update just your top-level config file each January 1st, instead of hunting through your templates.

{{if .Site.Params.CopyrightHTML}}<footer>
<div class="text-center">{{.Site.Params.CopyrightHTML | safeHtml}}</div>
</footer>{{end}}

An alternative way of writing the “if” and then referencing the same value is to use “with” instead. With rebinds the context . within its scope, and skips the block if the variable is absent:

{{with .Site.Params.TwitterUser}}<span class="twitter">
<a href="https://twitter.com/{{.}}" rel="author">
<img src="/images/twitter.png" width="48" height="48" title="Twitter: {{.}}"
 alt="Twitter"></a>
</span>{{end}}

Finally, if you want to pull “magic constants” out of your layouts, you can do so, such as in this example:

<nav class="recent">
  <h1>Recent Posts</h1>
  <ul>{{range first .Site.Params.SidebarRecentLimit .Site.Recent}}
    <li><a href="{{.RelPermalink}}">{{.Title}}</a></li>
  {{end}}</ul>
</nav>
