Position	Returns the filename and position from which the shortcode was called.			related returnType signatures methods/shortcode/Name functions/fmt/Errorf text.Position SHORTCODE.Position

The Position method is useful for error reporting. For example, if your shortcode requires a "greeting" parameter:

{{< code file=layouts/shortcodes/myshortcode.html lang=go-html-template >}} {{ $greeting := "" }} {{ with .Get "greeting" }} {{ $greeting = . }} {{ else }} {{ errorf "The %q shortcode requires a 'greeting' parameter. See %s" .Name .Position }} {{ end }} {{< /code >}}

In the absence of a "greeting" parameter, Hugo will throw an error message and fail the build:

ERROR The "myshortcode" shortcode requires a 'greeting' parameter. See "/home/user/project/content/about.md:11:1"

{{% note %}} The position can relatively expensive to calculate. Limit its use to error reporting. {{% /note %}}
