RelRef	Returns the relative URL of the page with the given path, language, and output format.			related returnType signatures methods/page/Ref functions/urls/Ref functions/urls/RelRef string PAGE.RelRef OPTIONS

The map of option contains:

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.

The examples below show the rendered output when visiting a page on the English language version of the site:

{{ $opts := dict "path" "/books/book-1" }}
{{ .RelRef $opts }} → /en/books/book-1/

{{ $opts := dict "path" "/books/book-1" "lang" "de" }}
{{ .RelRef $opts }} → /de/books/book-1/

{{ $opts := dict "path" "/books/book-1" "lang" "de" "outputFormat" "json" }}
{{ .RelRef $opts }} → /de/books/book-1/index.json

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.
