The first argument is the context of the page from which to resolve relative paths, typically the current page.
The second argument is a path to a page, with or without a file extension, with or without an anchor. A path without a leading `/` is first resolved relative to the given context, then to the remainder of the site. Alternatively, provide an [options map](#options) instead of a path.
```go-html-template
{{ ref . "about" }}
{{ ref . "about#anchor" }}
{{ ref . "about.md" }}
{{ ref . "about.md#anchor" }}
{{ ref . "#anchor" }}
{{ ref . "/blog/my-post" }}
{{ ref . "/blog/my-post.md" }}
```
## Options
Instead of specifying a path, you can also provide an options map:
path
: (`string`) The path to the page, relative to the content directory. Required.
lang
: (`string`) The language (site) to search for the page. Default is the current language. Optional.
outputFormat
: (`string`) The output format to search for the page. Default is the current output format. Optional.
To return the absolute permalink to another language version of a page:
```go-html-template
{{ ref . (dict "path" "about.md" "lang" "fr") }}
```
To return the absolute permalink to another Output Format of a page:
```go-html-template
{{ ref . (dict "path" "about.md" "outputFormat" "rss") }}
```
By default, Hugo will throw an error and fail the build if it cannot resolve the path. You can change this to a warning in your site configuration, and specify a URL to return when the path cannot be resolved.
{{< code-toggle file=hugo >}}
refLinksErrorLevel = 'warning'
refLinksNotFoundURL = '/some/other/url'
{{< /code-toggle >}}
