Code Example block

If you're using the VF Nunjucks environment, you can utilise the {% codeblock 'html' -%}{% endcodeblock %} tag to assist generating pre-formatted content.

<pre class="vf-code-example__pre">
<code class="vf-code-example">
<your special code here>
Maybe some html tags?
<link rel="stylesheet" href="https://aurl">
<script src="https://aurl"></script>
Nunjucks syntax

Depending on your environment you'll want to use render or include. As a rule of thumb: server-side use include, precompiled browser use render. If you're using vf-eleventy you should use include.

Using include

You'll need to pass a context object from your code or Yaml file (example), as well as the path to the Nunjucks template. Nunjucks' include is an abstraction of render and provides some additional portability.

{% set context fromYourYamlFile %}
- or -
{% set context = { 
"component-type" : "block",
{% include "../path_to/vf-code-example/vf-code-example.njk" %}

Using render

This approach is best for bare-bones Nunjucks environments, such as precompiled templates with the Nunjucks slim runtime where include is not be available.

{% render '@vf-code-example', {
  "component-type" : "block",}
<pre class="vf-code-example__pre"><code class="Code Code--lang-html vf-code-example"><span class="hljs-tag">&lt;<span class="hljs-name">pre</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"vf-code-example__pre"</span>&gt;</span>
<span class="hljs-tag">&lt;<span class="hljs-name">code</span> <span class="hljs-attr">class</span>=<span class="hljs-string">"vf-code-example"</span>&gt;</span>
<span class="hljs-tag">&lt;<span class="hljs-name">your</span> <span class="hljs-attr">special</span> <span class="hljs-attr">code</span> <span class="hljs-attr">here</span>&gt;</span>
Maybe some html tags?
<span class="hljs-tag">&lt;<span class="hljs-name">link</span> <span class="hljs-attr">rel</span>=<span class="hljs-string">"stylesheet"</span> <span class="hljs-attr">href</span>=<span class="hljs-string">"https://aurl"</span>&gt;</span>
<span class="hljs-tag">&lt;<span class="hljs-name">script</span> <span class="hljs-attr">src</span>=<span class="hljs-string">"https://aurl"</span>&gt;</span><span class="hljs-tag">&lt;/<span class="hljs-name">script</span>&gt;</span>
<span class="hljs-tag">&lt;/<span class="hljs-name">code</span>&gt;</span>
<span class="hljs-tag">&lt;/<span class="hljs-name">pre</span>&gt;</span>
