relLangURL	Returns a relative URL with a language prefix, if any.	functions	docs parent functions	urls multilingual i18n	relLangURL INPUT

Use this function with both monolingual and multilingual configurations. The URL returned by this function depends on:

• Whether the input begins with a slash
• The baseURL in site configuration
• The language prefix, if any

In examples that follow, the project is multilingual with content in both Español (es) and English (en). The default language is Español. The returned values are from the English site.

Input does not begin with a slash

If the input does not begin with a slash, the resulting URL will be correct regardless of the baseURL.

With baseURL = https://example.org/

{{ relLangURL "" }}           →   /en/
{{ relLangURL "articles" }}   →   /en/articles
{{ relLangURL "style.css" }}  →   /en/style.css

With baseURL = https://example.org/docs/

{{ relLangURL "" }}           →   /docs/en/
{{ relLangURL "articles" }}   →   /docs/en/articles
{{ relLangURL "style.css" }}  →   /docs/en/style.css

Input begins with a slash

If the input begins with a slash, the resulting URL will be incorrect when the baseURL includes a subdirectory. With a leading slash, the function returns a URL relative to the protocol+host section of the baseURL.

With baseURL = https://example.org/

{{ relLangURL "/" }}          →   /en/
{{ relLangURL "/articles" }}  →   /en/articles
{{ relLangURL "/style.css" }} →   /en/style.css

With baseURL = https://example.org/docs/

{{ relLangURL "/" }}          →   /en/
{{ relLangURL "/articles" }}  →   /en/articles
{{ relLangURL "/style.css" }} →   /en/style.css

{{% note %}} The last three examples are not desirable in most situations. As a best practice, never include a leading slash when using this function. {{% /note %}}
