I needed to embed a GitLab Snippet into a page here on the site earlier today
so I added layouts/shortcodes/snippet.html with the content below.
<script src="https://gitlab.com/-/snippets/{{ index .Params 0 }}.js"></script>
Now I can embed snippets just like Gists except using snippet in place of gist and it only takes the single number parameter. I’d put an example here but I can’t figure out how to make Hugo ignore it.
