{{% include "/_common/functions/fmt/format-string.md" %}}

The `errorf` function evaluates the format string, then prints the result to the ERROR log and fails the build.

```go-html-template
{{ errorf "The %q shortcode requires a src argument. See %s" .Name .Position }}
```

Use the [`erroridf`] function to allow optional suppression of specific errors.
