Chapter 3

Shortcodes

Hugo uses Markdown for its simple content format. However, there are a lot of things that Markdown doesn’t support well. You could use pure HTML to expand possibilities.

But this happens to be a bad idea. Everyone uses Markdown because it’s pure and simple to read even non-rendered. You should avoid HTML to keep it as simple as possible.

To avoid this limitations, Hugo created shortcodes. A shortcode is a simple snippet inside a page.

The Relearn theme provides multiple shortcodes on top of existing ones.

Attachments

List of files attached to a page

Button

Clickable buttons

Children

List the child pages of a page

Expand

Expandable/collapsible sections of text

Subsections of Shortcodes

Attachments

The attachments shortcode displays a list of files attached to a page with adjustable color, title and icon.

Usage

While the examples are using shortcodes with named parameter you are free to also call this shortcode from your own partials.

{{% attachments sort="asc" /%}}
{{ partial "shortcodes/attachments.html" (dict
  "context" .
  "sort" "asc"
)}}

The shortcurt lists files found in a specific folder.

Currently, it supports two implementations for pages

  1. If your page is a Markdown file, attachements must be placed in a folder named like your page and ending with .files.

    • content
      • _index.md
      • page.files
        • attachment.pdf
      • page.md
  2. If your page is a folder, attachements must be placed in a nested files folder.

    • content
      • _index.md
      • page
        • index.md
        • files
          • attachment.pdf

Be aware that if you use a multilingual website, you will need to have as many folders as languages.

Parameter

Name Default Notes
style transparent The color scheme used to highlight the box content.

- by severity: info, note, tip, warning<nd color: primary, secondary
- by color: blue, green, grey, orange, red
- by special color: default,t`
title see notes Arbitray text for the box title. Depending on the style there may be a default title. Any given value will overwault.

If you want no icon, you have to set this parameter to " " (a non empty d with spaces)
sort asc Sorting the output in ascending or descending order.
pattern .* A regular expressions, used to filter the attachments by file name. For example:

- to match a file suffix of ‘jpg’, use .*jpg (not *.jpg)
- to match file names ending in jpg or png, use .*(jpg|png)

Examples

Custom Title, List of Attachments Ending in pdf or mp4

{{% attachments title="Related files" pattern=".*(pdf|mp4)" /%}}

Info Styled Box, Descending Sort Order

```

> the possiblities are endless (almost - including other shortcodes may or may not work)
{{% /expand %}}
Show me almost endless possibilities

Include

The include shortcode includes other files from your project inside of the current page.

Usage

While the examples are using shortcodes with named parameter you are free to use positional aswell or also call this shortcode from your own partials.

{{% include file="shortcodes/INCLUDE_ME.md" %}}
{{% include "shortcodes/INCLUDE_ME.md" %}}
{{ partial "shortcodes/include .html" (dict

...and even source code

the possiblities are endless (almost - including other shortcodes may or may not work) (almost - including other shortcodes may or may not work)

Math

The math shortcode generates beautiful formatted math and chemical formulae using the MathJax library.

$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$
Note

This only works in modern browsers.

Usage

While the examples are using shortcodes with named parameter it is recommended to use codefences instead. This is because more and more other software supports Math codefences (eg. GitHub) and so your markdown becomes more portable.

You are free to also call this shortcode from your own partials.

Note

To use codefence syntax you have to turn off guessSyntax for the markup.highlight setting (see the configuration section).

```math
$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$
```
{{< math >}}
$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$
{{< /math >}}
{{ partial "shortcodes/math.html" (dict
  "context" .
  "content" "$$left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$"
)}}

Parameter

Parameter are only supported when using shortcode or partial syntax. Defaults are used when using codefence syntax.

Name Default Notes
align center Allowed values are left, center or right.
<content> <empty> Your formuale.

Configuration

MathJax is configured with default settings. You can customize MathJax’s default settings for all of your files thru a JSON object in your config.toml or override these settings per page thru your pages frontmatter.

The JSON object of your config.toml / frontmatter is forwarded into MathJax’s configuration object.

See MathJax documentation for all allowed settings.

Note

To use codefence syntax you have to turn off guessSyntax for the markup.highlight setting.

Global Configuration File

[params]
  mathJaxInitialize = "{ \"chtml\": { \"displayAlign\": \"left\" } }"

[markup]
  [markup.highlight]
    # if `guessSyntax = true`, there will be no unstyled code even if no language
    # was given BUT Mermaid and Math codefences will not work anymore! So this is a
    # mandatory setting for your site if you want to use Math codefences
    guessSyntax = false

Page’s Frontmatter

Examples

Inline Math

Inline math is generated if you use a single `$` as a delimiter around your formulae: {{< math >}}$\sqrt{3}${{< /math >}}

Inline math is generated if you use a single $ as a delimiter around your formulae: $\sqrt{3}$

Blocklevel Math with Left Alignment

If you delimit your formulae by two consecutive `$$` it generates a new block.

{{< math align="left" >}}
$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$
{{< /math >}}

$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$

Codefence

You can also use codefences but without further parameter.

```math
$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$
```
$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$

Mermaid

The mermaid shortcode generates diagrams and flowcharts from text, in a similar manner as Markdown using the Mermaid library.

graph LR; If --> Then Then --> Else
Note

This only works in modern browsers.

Warning

Due to limitations with Mermaid, it is currently not possible to use Mermaid code fences in an initially collapsed expand shortcode. This is a know issue and can’t be fixed by this theme.

Usage

While the examples are using shortcodes with named parameter it is recommended to use codefences instead. This is because more and more other software supports Mermaid codefences (eg. GitHub) and so your markdown becomes more portable.

You are free to also call this shortcode from your own partials.

Note

To use codefence syntax you have to turn off guessSyntax for the markup.highlight setting (see the configuration section).

```mermaid
graph LR;
    If --> Then
    Then --> Else
```
{{< mermaid >}}
graph LR;
    If --> Then
    Then --> Else
{{< /mermaid >}}
{{ partial "shortcodes/mermaid.html" (dict
  "context" .
  "content" "graph LR;\nIf --> Then\nThen --> Else"
)}}

The generated graphs can be be panned by dragging them and zoomed by using the mousewheel. On mobile devices you can use finger gestures.

Parameter

Parameter are only supported when using shortcode or partial syntax. Defaults are used when using codefence syntax.

Name Default Notes
align center Allowed values are left, center or right.
<content> <empty> Your Mermaid graph.

Configuration

Mermaid is configured with default settings. You can customize Mermaid’s default settings for all of your files thru a JSON object in your config.toml, override these settings per page thru your pages frontmatter or override these setting per diagramm thru diagram directives.

The JSON object of your config.toml / frontmatter is forwarded into Mermaid’s mermaid.initialize() function.

See Mermaid documentation for all allowed settings.

The theme setting can also be set by your used color variant. This will be the sitewide default and can - again - be overridden by your settings in config.toml, frontmatter or diagram directives.

Note

To use codefence syntax you have to turn off guessSyntax for the markup.highlight setting.

Global Configuration File

[params]
  mermaidInitialize = "{ \"theme\": \"dark\" }"

[markup]

Site param

The siteparam shortcode prints values of site params.

Usage

While the examples are using shortcodes with named parameter you are free to use positional aswell or call this shortcode from your own partials.

{{% siteparam name="editURL" %}}
{{% siteparam "editURL" %}}
{{ partial "shortcodes/siteparam.html" (dict
  "context" .
  "name" "editURL"
)}}

Parameter

Name Position Default Notes
name 1 <empty> The name of the site param to be displayed.

Examples

editURL from config.toml

`editURL` value: {{% siteparam name="editURL" %}}

editURL value: https://github.com/McShelby/hugo-theme-relearn/edit/main/exampleSite/content/

Swagger

This shortcode uses the RapiDoc library to display your Swagger / OpenAPI Specifications.

Note

This only works in modern browsers.

Usage

While the examples are using shortcodes with named parameter you are free to also call this shortcode from your own partials.

{{< swagger src="https://petstore3.swagger.io/api/v3/openapi.json" >}}
{{ partial "shortcodes/swagger.html" (dict
  "context" .
  "src" "https://petstore3.swagger.io/api/v3/openapi.json"
)}}

Parameter

Name Default Notes
src <empty> The URL to the OpenAPI Specification file. This can be relative to the URL of your page if it is a leaf or branch bundle.
Note

If you want to print out (or generate a PDF) from your Swagger documentation, don’t initiate printing directly from the page because the elements are optimized for interactive usage in a browser.

Instead, open the print preview in your browser and initiate printing from that page. This page is optimized for reading and expands most of the available sections.

Configuration

Swagger is configured with default settings. You can customize Swagger’s default settings for all of your files thru a JSON object in your config.toml or override these settings per page thru your pages frontmatter.

The JSON object of your config.toml / frontmatter is forwarded into Swagger’s initialization. At the moment, only the theme setting is supported.

The theme setting can also be set by your used color variant. This will be the sitewide default and can - again - be overridden by your settings in config.toml or frontmatter.

Global Configuration File

[params]
  swaggerInitialize = "{ \"theme\": \"dark\" }"

Example

Using Local File

{{< swagger src="petstore.json" >}}

Tabbed views

The tabs shortcode displays arbitrary content in unlimited number of tabs. This comes in handy eg. for providing code snippets for multiple languages or providing configuration in different formats.

print("Hello World!")
echo "Hello World!"

Usage

While the examples are using shortcodes with named parameter you are free to also call this shortcode from your own partials.

{{< tabs >}}
{{% tab name="python" %}}
```python
print("Hello World!")
```
{{% /tab %}}
{{% tab name="bash" %}}
```bash
echo "Hello World!"
```
{{% /tab %}}
{{< /tabs >}}
{{ partial "shortcodes/tabs.html" (dict
  "context" .
  "tabs" (slice
    (dict
      "name" "python"
      "content" ("```python\nprint(\"Hello World!\")\n```" | markdownify)
    )
    (dict
      "name" "bash"
      "content" ("```bash\necho \"Hello World!\"\n```" | markdownify)
    )
  )
)}}

Parameter

Name Default Notes
groupid default Arbitrary name of the group the tab view belongs to.

Tab views with the same groupid sychronize their selected tab. This sychronization applies to the whole site!
<content> <empty> Arbitrary number of tabs defined with the tab sub-shortcode.
Note

When using tab views with different content sets, make sure to use a common groupid for equal sets of tabs but distinct groupid for different sets.

The tab selection is restored automatically based on the groupid and if it cannot find a tab item because it came from the 'default' group on a different page then the first tab is selected instead.

Examples

Distinct groupid

{{< tabs groupid="config" >}}
{{% tab name="json" %}}
```json
{
  "Hello": "World"
}
```
{{% /tab %}}
{{% tab name="XML" %}}
```xml
<Hello>World</Hello>
```
{{% /tab %}}
{{% tab name="properties" %}}
```properties
Hello = World
```
{{% /tab %}}
{{< /tabs >}}
{
  "Hello": "World"
}
<Hello>World</Hello>
Hello = World

Non-Distinct groupid

See what happens to this tab view if you select properties tab from the previous example.

{{< tabs groupid="config" >}}
{{% tab name="json" %}}
```json
{
  "Hello": "World"
}
```
{{% /tab %}}
{{% tab name="XML" %}}
```xml
<Hello>World</Hello>
```
{{% /tab %}}
{{< /tabs >}}
{
  "Hello": "World"
}
<Hello>World</Hello>
