This will install the extension under the _extensions subdirectory. If you’re using version control, you will want to check in this directory.

Once you’ve install the extension, you can use the {{< partial file ... >}} shortcode to include partial content from file in your Quarto document!

Use the {{< partial file ... >}} shortcode to include partial content from file in your Quarto document. The partial content can use mustache templating syntax and you can provide named key-value pairs in the shortcode to provide the template data.

For example, _hello.md contains the following content

Hello, {{ name }}!

and we can include the partial, providing our own value for {{ name }}:

{{< partial _hello.md name="weary traveler" >}}

Hello, weary traveler!

You can also include the partial data in the frontmatter of your document, using the partial-data key, e.g. 

partial-data:
  name: "friend"

{{< partial _hello.md >}}

Or used inline: To you I say "{{< partial _hello.md >}}"

Hello, !

Or used inline: To you I say “Hello, !”

Alternatively, the second argument of the shortcode can point to a custom key in your YAML frontmatter, e.g.

my-data:
  friends:
    name: amigo

{{< partial _hello.md my-data.friends >}}

Hello, !

Another, possibly less convenient, option is to provide JSON in the shortcode data. Any key-value pair that starts with { or [ will be parsed into a JSON object or array.

Note that the file type affects the output. The next example, in addition to using JSON data, uses a .qmd file to render the output as Quarto-processed markdown.

::: {.callout-tip title="Hi there!"}
{{#person}}
Hello, {{ honorific }} {{ name.first }} {{ name.last }}!
{{/person}}
:::

{{< partial _hello_first_last.qmd person='{"honorific": "Mr.", "name": {"first": "Garrick", "last": "Aden-Buie"}}' >}}

[!TIP]

Hi there!

Hello, Mr. Garrick Aden-Buie!

Finally, remember that you can use the full power of mustache templating! The next example creates a markdown list from an array of my favorite fruits.

These are a few of my favorite fruits:

{{#fruits}}
- {{.}}
{{/fruits}}

{{< partial _favorite_fruits.md fruits='["apple", "banana", "coconut", "mango"]' >}}

These are a few of my favorite fruits:

• apple
• banana
• coconut
• mango

partials embeds lustache, a pure-Lua implementation of mustache. Thanks to the authors and contributors of these projects!

Thanks, as always, to the developers of Quarto!
