Installing

quarto add shafayetShafee/downloadthis

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

Using

To embed a file downloadable from the rendered html document, use the {{< downloadthis >}} shortcode. For example,

{{< downloadthis image.png >}}

would create a download button styled with bootstrap with which file.png can be downloaded.

Options

There are six additional arguments you can specify for this shortcode, which are,

• dname : The filename (without file extension!) which will be assigned to the downloaded file (default value is file)
• label : Button label (default is Download).
• icon: Bootstrap Icon for the button (default is download).
• type: Bootstrap button styles, which are primary, secondary, success, warning, danger, info, light, dark, light (default value is default).
• class: CSS class to be assigned to this button.
• id: CSS id to be assigned to this button.

An example using all these arguments as follows,

{{< downloadthis files/mtcars.csv dname="mtcars.csv" label="Download the mtcars data" icon="database-fill-down" type="info" >}}

where mtcars.csv is in a folder named files and the files folder is in the same folder with source .qmd file.

Styling Buttons

Using the option class or id, it is very simple to style the button using CSS.

See the example_styling.qmd for an example and the rendered html output

Example

Here is the source code for examples: example.qmd and the rendered html output: example.html
