A Templater script and template to insert a Hugo figure shortcode linked to one of the document's linked attachments.
Hugo's figure shortcodes are an easy way to make embedded media more accessible. They might make it more stylable but my only real concern was getting my embeds up to modern standards.
Hugo itself doesn't understand wikilinks of the form [[target]], or with aliases, etc. There are tools like Quartz which do the job for you with some templating magic.
I'm assuming that you have something that can perform a similar task.
This is the actually interesting part of the project. This snippet of code iterates through all the outlinks in a document, checks which ones have a type of file, and presents a unique list of those links. This is nice, because it doesn't even care what directory you keep your attachments in.
The template itself is really simple, just calling attachmentSelector() and linking to the file.
{{< figure src="[[<% await tp.user.attachmentSelector(tp, tp.file.path(true)) %>]]" title="" alt="" caption="" >}}
attachmentSelector.js is intended to be used as a Templater user script. You'll want to configure Templater's user script directory, and drop it in there.
Similarly, blog-figure.md should be moved into your configured templates folder.
Let's say you've got a document that looks something like this:
---
title: "How to make money selling your bones"
tags:
- advice
- finance

Selecting your attachment will complete the process and emit your Hugo shortocde. This respects the stated assumption that Hugo or your publishing pipeline has some way of transforming Obsidian/wikilinks into something that Hugo understands.
