| Custom hugo markdown shortcode | 2021-03-22 | An example of custom hugo shortcode to calculate automatically something |
|
Introduction
On the [about-me]({{< ref "about-me" >}}) page I had hardcoded my age. I wanted a way to calculate it automatically when building the site, here is how to do this.
Adding the shortcode
Added a custom markdown shortcode in hugo in as simple as creating a layouts/shortcodes/ directory. Each html file created inside will define a shortcode from the filename. In my example I want to calculate my age so I named the shortcode age.html and added the following simple template code :
{{ div (sub now.Unix 493473600 ) 31556926 }}
The first number is the timestamp of my birthday, the second represents how many seconds there are in a year.
Using the shortcode
With this layouts/shortcodes/age.html file I can just add the following in a page to add my age :
{{< print "{{% age %}}" >}}
And if you are wondering how I am able to display a shortcode code inside this page without having it render, it is because I defined another shortcode that does exactly like this :
{{< print "{{ index .Params 0 }}" >}}
You can find these examples here! Hugo really is a powerful static website generator, it is amazing.
