Position	Returns the file name and position from which the shortcode was called.			functions_and_methods returnType signatures text.Position SHORTCODE.Position

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

{{ $greeting := "" }}
{{ with .Get "greeting" }}
  {{ $greeting = . }}
{{ else }}
  {{ errorf "The %q shortcode requires a 'greeting' argument. See %s" .Name .Position }}
{{ end }}

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

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

[!note] The position can be expensive to calculate. Limit its use to error reporting.
