relLangURL	Adds the relative URL with correct language prefix according to site configuration for multilingual.		2017-02-01	2017-02-01	2017-02-01	functions	docs parent functions	relLangURL INPUT				false

absLangURL and relLangURL functions are similar to their absURL and relURL relatives but will add the correct language prefix when the site is configured with more than one language. (See Configuring Multilingual.)

So for a site baseURL set to https://example.com/hugo/ and the current language is en:

{{ "blog/" | absLangURL }} → "https://example.com/hugo/en/blog/"
{{ "blog/" | relLangURL }} → "/hugo/en/blog/"
