[solved] Is it possible to create a counter in Shortcodes? [YES!]

I’m trying to power-up the built-in Shortcode for highlighting code with Pygments. My plan is to generate something like this HTML:

<figure class="code">
    <div class="highlight">
        ... like actual shortcode ...
    </div>
    <figcaption>
        Listing COUNTER: CAPTION-TEXT
    </figcaption>
</figure>

My last problem to solve: Is there a way to get the COUNTER auto-generated as an integer by hugo?

The figure-wrapping and the caption is not a problem at all I think, it should be just another parameter in the call of the new paired shortcode.

[update] Solved it using Scratch. Here is my new shortcode called “listing” line-breaks just for being readable:

<figure class="code">
{{ if .Get "config" }}
  {{ highlight .Inner (.Get "lang") (.Get "config") }}
{{ else }}
  {{ highlight .Inner (.Get "lang") "" }}
{{ end }}
{{ if .Get "caption" }}
  <figcaption>
    Listing
    {{ .Page.Scratch.Add "count" 1 }}
    {{ .Page.Scratch.Get "count" }}: 
    {{ .Get "caption" | markdownify }}
  </figcaption>
{{ end }}
</figure>

Usage:

{{< listing lang="shell" config="linenos=inline" caption="Caption." >}}
Your code goes here
{{< / listing >}}
