Hugo hits The Hundy

As Hugo reaches version 0.100.x, the venerable SSG improves upon its handling of shortcodes.

2022-06-07

Last week, the Hugo static site generator (SSG) hit The Big One-Zero-Zero — namely, version 0.100.0, but I’ll call it 0.100.x given that it’s since been tweaked to 0.100.1.

(No, it didn’t go to v.1.0. More on that at the end.)

As Hugo maintainer Bjørn Erik Pedersen explained in the release notes, this version’s main purpose took the form of improvements to Hugo’s shortcodes. And this post’s main purpose is to show you what those are.

Shortcodes in Markdown files

The whole purpose of shortcodes is making it easy to add small, reusable snippets to your site’s Markdown content. Now, with Hugo 0.100.x, a Markdown file (.md) can be a shortcode for the first time. This means that you won’t have to use HTML to create a shortcode that’s only for providing some sort of text. Since I had multiple shortcodes that fit that description, I was pleased to see this new capability.

Let’s say you occasionally want to drop in a standard disclaimer, and so you’ve made a shortcode for it rather than having to repeat the thing every time (the link is bogus):

Disclaimer: This data is provided only for comparison and does not necessarily reflect the opinion of this company.

Up to now, that would’ve had to be an HTML file:

<div class="blueBox">
<p><strong>Disclaimer</strong>: This data is provided only for comparison and does <strong>not</strong> necessarily reflect the opinion of <a href="{{ .Site.BaseUrl }}/about/" rel="nofollow">this company</a>.</p>
</div>

Now, with Markdown as a shortcode format, the typing1 is easier:

**Disclaimer**: This data is provided only for comparison and does **not** necessarily reflect the opinion of [this company]({{ .Site.BaseUrl }}about/).
{.box}

Respect the indents

Before Hugo 0.100.0, inserting a shortcode within indented content, such as a list item (li) within an ordered or unordered list (ol or ul, respectively), would produce unwanted results. To borrow from the example given in the 0.100.0 release notes, imagine a shortcode, ourList.html, that’s just a frequently provided list of items (we’ll do it without the <ol> or <ul>, to leave room for multiple use cases):

<li><a href="/products/">Products</a></li>
<li><a href="/services/">Services</a></li>
<li><a href="/locations/">Locations</a></li>
<li><a href="/our-team/">Our team</a></li>

Okay, fine. So if you want to turn that into sub-bullets within a bulleted list, you might do this:

- More about us
{{% ourList %}}
- [Why buy from us?](/why-buy/)
- [What our customers say](/testimonials/)

Prior to v.0.100.0, this would result in the following (as before, the links are bogus):

But, starting with Hugo 0.100.0, you get the desired indenting:

Note: I purposely altered the example from the release notes, which showed a shortcode that was in Markdown — although, as pointed out earlier, that wasn’t possible before v.0.100.0 in the first place. Um, oops?

More goodies

All of this is possible because, as of v.0.100.0, Hugo’s $page.RenderString function supports shortcodes. Hugo expert Régis Philibert, as he often does on such occasions, grasped added significance from the details in the release notes:

This means shortcodes in your @GoHugoIO Front Matter!

Page Builder blocks etc… 🎉.

Finally, 0.100.0 added a new resources.Copy function to Hugo’s asset pipeline, Hugo Pipes. The documentation says it’s “possibly most useful for renaming things” — as in this example (also from the documentation), in which Hugo’s built-in image-processing capability comes into play:

{{ $resized := $image.Resize "400x400" |  resources.Copy "images/mynewname.jpg" }}
<img src="{{ $resized.RelPermalink }}">

Looking out for Number One?

If you’d noticed Hugo’s v.0.99.0 release on May 16, you might have thought, as I did, “Aha, this means the long-awaited version 1 is near.” After all, Hugo’s first public release was on July 4, 2013, as v.0.7.

However, on the day of the 0.100.0 release, Pedersen explained in the Hugo Discourse forum why that wasn’t to be the case just yet:

The one thing we signal by not going 1.x is that we’re kind of not “1.0 feature complete.” People tend to think a major version would get a more stable version, which I’m not sure is always the case. I suspect you end up with major version increments and, due to lack of human resources, not so much back-ports of bug fixes to the previous version(s).

Bottom line: only when Pedersen and those who help him code Hugo decide that the time is right will Hugo go to version 1. It’ll happen when it happens. End of story.


  1. Note that the link-handling here will be the same as in the HTML version if you’ve used a render-link template accordingly. As for that {.box} item, that’s an attribute; combined with my site’s styling, it accomplishes the same thing as <div class="blueBox"><p>[content]</p></div> in the HTML shortcode. This is made possible by the appropriate goldmark setting in your Hugo project’s config file, as I explained in last year’s “New in Hugo: easier writing.” ↩︎
