# Multilingual and i18n

The Relearn theme is fully compatible with Hugo multilingual mode.

It provides:

- Translation strings for default values (English, Arabic, Simplified Chinese, Traditional Chinese, Czech, Dutch, Finnish French, German, Hindi, Indonesian, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Turkish, Vietnamese). Feel free to contribute!
- Support for languages written right to left
- Automatic menu generation from multilingual content
- In-browser language switching

## Basic configuration

After learning how Hugo handle multilingual websites, define your languages in your `config.toml` file.

For example with current English and Piratized English website.

Note

Make sure your default language is defined as the first one in the `[Languages]` array, as the theme needs to make assumptions on it

    # English is the default language
    defaultContentLanguage = "en"

    [Languages]
    [Languages.en]
    title = "Hugo Relearn Theme"
    weight = 1
    languageName = "English"

    [Languages.pir]
    title = "Cap'n Hugo Relearrrn Theme"
    weight = 2
    languageName = "Arrr! Pirrrates"

Then, for each new page, append the id of the language to the file.

- Single file `my-page.md` is split in two files:
  - in English: `my-page.md`
  - in Piratized English: `my-page.pir.md`
- Single file `_index.md` is split in two files:
  - in English: `_index.md`
  - in Piratized English: `_index.pir.md`

Info

Be aware that only translated pages are displayed in menu. It’s not replaced with default language content.

Tip

Use slug frontmatter parameter to translate urls too.

## Search

In case each page’s content is written in one single language only, the above configuration will already configure the site’s search functionality correctly.

Warning

Although the theme supports a wide variety of supported languages, the site’s search via the Lunr search library does not. You’ll see error reports in your browsers console log for each unsupported language. Currently unsupported are:

- Czech
- Indonesian
- Polish

### Search with mixed language support

In case your page’s content contains text in multiple languages (e.g. you are writing a Russian documentation for your english API), you can add those languages to your `config.toml` to broaden search.

    [params]
      additionalContentLanguage = [ "en" ]

As this is an array, you can add multiple additional languages.

Note

Keep in mind that the language code required here, is the base language code. E.g. if you have additional content in `zh-CN`, you have to add just `zh` to this parameter.

## Overwrite translation strings

Translations strings are used for common default values used in the theme (Edit button, Search placeholder and so on). Translations are available in English and Piratized English but you may use another language or want to override default values.

To override these values, create a new file in your local i18n folder `i18n/<idlanguage>.toml` and inspire yourself from the theme `themes/hugo-theme-relearn/i18n/en.toml`

## Disable language switching

Switching the language in the browser is a great feature, but for some reasons you may want to disable it.

Just set `disableLanguageSwitchingButton=true` in your `config.toml`

    [params]
      # When using multilingual website, disable the switch language button.
      disableLanguageSwitchingButton = true
