The `Position` method is useful for error reporting. For example, if your shortcode requires a "greeting" parameter:
|
|
|
|
{{< code file=layouts/shortcodes/myshortcode.html >}}
|
|
{{ $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:
|
|
|
|
```text
|
|
ERROR The "myshortcode" shortcode requires a 'greeting' parameter. See "/home/user/project/content/about.md:11:1"
|
|
```
|
|
|
|
{{% note %}}
|
|
The position can be expensive to calculate. Limit its use to error reporting.

|
{{% /note %}}
