urls.RelLangURL - Hugo

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 your project configuration
The language prefix, if any

This is the project configuration for the examples that follow:

{{< code-toggle file=hugo >}} defaultContentLanguage = 'en' defaultContentLanguageInSubdir = true [languages.en] weight = 1 [languages.es] weight = 2 {{< /code-toggle >}}

Input does not begin with a slash

If the input does not begin with a slash, the resulting URL will be relative to the baseURL in your project configuration.

When rendering the en site with baseURL = https://example.org/

go-html-template

{{ relLangURL "" }}                         → /en/
{{ relLangURL "articles" }}                 → /en/articles
{{ relLangURL "style.css" }}                → /en/style.css
{{ relLangURL "https://example.org" }}      → https://example.org
{{ relLangURL "https://example.org/" }}     → /en
{{ relLangURL "https://www.example.org" }}  → https://www.example.org
{{ relLangURL "https://www.example.org/" }} → https://www.example.org/

When rendering the en site with baseURL = https://example.org/docs/

go-html-template

{{ relLangURL "" }}                           → /docs/en/
{{ relLangURL "articles" }}                   → /docs/en/articles
{{ relLangURL "style.css" }}                  → /docs/en/style.css
{{ relLangURL "https://example.org" }}        → https://example.org
{{ relLangURL "https://example.org/" }}       → https://example.org/
{{ relLangURL "https://example.org/docs" }}   → https://example.org/docs
{{ relLangURL "https://example.org/docs/" }}  → /docs/en
{{ relLangURL "https://www.example.org" }}    → https://www.example.org
{{ relLangURL "https://www.example.org/" }}   → https://www.example.org/

Input begins with a slash

If the input begins with a slash, the resulting URL will be relative to the protocol+host of the baseURL in your project configuration.

When rendering the en site with baseURL = https://example.org/

go-html-template

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

When rendering the en site with baseURL = https://example.org/docs/

go-html-template

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

[!note] As illustrated by the previous example, using a leading slash is rarely desirable and can lead to unexpected outcomes. In nearly all cases, omit the leading slash.
