Code Blocks

There are several ways to add code blocks. Most of them work out of the box, only the Hugo shortcode <highlight> needs to be configured to work properly. The theme also provides some additional features like a copy button and an option to set the maximum length of code blocks. Both of these functions and the dependent formatting rely on the .highlight CSS class. You must ensure that you always assign a language to your code blocks if you want to use these functions. If you do not want to apply syntax highlighting, you can also specify plain or text as the language.

{{< toc >}}

Inline code

To display an inline shortcode use single quotes:

`some code`

Example: some code with a link

Code blocks

Code blocks can be uses without language specification:

```Plain
some code
```

Example:

some code

... or if you need language specific syntax highlighting:

```Shell
# some code
echo "Hello world"
```

Example:

# some code
echo "Hello World"

Highlight shortcode

Hugo has a build-in shortcode for syntax highlighting. To work properly with this theme, you have to set following options in your site configuration:

{{< tabs "uniqueid" >}} {{< tab "TOML" >}}

pygmentsUseClasses=true
pygmentsCodeFences=true

{{< /tab >}} {{< tab "YAML" >}}

pygmentsUseClasses: true
pygmentsCodeFences: true

{{< /tab >}} {{< /tabs >}}

You can use it like every other shortcode:

{{</* highlight Shell "linenos=table" */>}}
# some code
echo "Hello World"
{{</* /highlight */>}}

Example:

{{< highlight Shell "linenos=table" >}}

some code

echo "Hello World" {{< /highlight >}}
