Hugo template to list all posts where you used the Instagram shortcode

instalist.html

<ul>
{{ $files := readDir "/content/post" }}
{{ range $file := $files }}
	{{ if in .Name ".md" }}
		{{ $match := printf "/content/post/%s" .Name | readFile | findRE "{{< instagram" }}
		{{ if $match }}
			<li><a href="/post/{{ strings.TrimSuffix ".md" .Name }}">{{ strings.TrimSuffix ".md" .Name }}</a></li>
		{{ end }}
	{{ end }}
{{ end }}
</ul>

If you use the instagram shortcode and want to list them somehow from another page, drop the above into a file in your shortcodes template directory and call it like:

{{< instalist >}}
