The `warnidf` function evaluates the format string, then prints the result to the WARNING log. Unlike the [`warnf`] function, you may suppress warnings logged by the `warnidf` function by adding the message ID to the `ignoreLogs` array in your site configuration.
|
|
|
|
This template code:
|
|
|
|
```go-html-template
|
|
{{ warnidf "warning-42" "You should consider fixing this." }}
|
|
```
|
|
|
|
Produces this console log:
|
|
|
|
```text
|
|
WARN You should consider fixing this.
|
|
You can suppress this warning by adding the following to your site configuration:
|
|
ignoreLogs = ['warning-42']
|
|
```
|
|
|
|
To suppress this message:
|
|
|
|
{{< code-toggle file=hugo >}}
|
|
ignoreLogs = ["warning-42"]
|
|
{{< /code-toggle >}}
|
|
|
|
[`warnf`]: /functions/fmt/warnf/
