In the `i18n`, the translations will be merged and take precedence over what is in the theme folder. Language files should be named according to [RFC 5646][] with names such as `en-US.toml`, `fr.toml`, etc. + +{{% note %}} +From **Hugo 0.31** you no longer need to use a valid language code. It _can be_ anything. + +See https://github.com/gohugoio/hugo/issues/3564 + +{{% /note %}} + +From within your templates, use the `i18n` function like this: + +``` +{{ i18n "home" }} +``` + +This uses a definition like this one in `i18n/en-US.toml`: + +``` +[home] +other = "Home" +``` + +Often you will want to use to the page variables in the translations strings. To do that, pass on the "." context when calling `i18n`: + +``` +{{ i18n "wordCount" . }} +``` + +This uses a definition like this one in `i18n/en-US.toml`: + +``` +[wordCount] +other = "This article has {{ .WordCount }} words." +``` +An example of singular and plural form: + +``` +[readingTime] +one = "One minute read" +other = "{{.Count}} minutes read" +``` +And then in the template: + +``` +{{ i18n "readingTime" .ReadingTime }} +``` - To track down missing translation strings, run Hugo with the `--i18n-warnings` flag: - - ``` - hugo --i18n-warnings | grep i18n - i18n|MISSING_TRANSLATION|en|wordCount - ``` + +## Customize Dates + +At the time of this writing, Go does not yet have support for internationalized locales, but if you do some work, you can simulate it. For example, if you want to use French month names, you can add a data file like ``data/mois.yaml`` with this content: + +~~~yaml +1: "janvier" +2: "février" +3: "mars" +4: "avril" +5: "mai" +6: "juin" +7: "juillet" +8: "août" +9: "septembre" +10: "octobre" +11: "novembre" +12: "décembre" +~~~ + +... then index the non-English date names in your templates like so: + +~~~html + +~~~ + +This technique extracts the day, month and year by specifying ``.Date.Day``, ``.Date.Month``, and ``.Date.Year``, and uses the month number as a key, when indexing the month name data file. + +## Menus + +You can define your menus for each language independently. The [creation of a menu][menus] works analogous to earlier versions of Hugo, except that they have to be defined in their language-specific block in the configuration file: + +``` +defaultContentLanguage = "en" + +[languages.en] +weight = 0 +languageName = "English" + +[[languages.en.menu.main]] +url = "/" +name = "Home" +weight = 0 + + +[languages.de] +weight = 10 +languageName = "Deutsch" + +[[languages.de.menu.main]] +url = "/" +name = "Startseite" +weight = 0 +``` + +The rendering of the main navigation works as usual. `.Site.Menus` will just contain the menu of the current language. Pay attention to the generation of the menu links. `absLangURL` takes care that you link to the correct locale of your website. Otherwise, both menu entries would link to the English version as the default content language that resides in the root directory. + +``` +
    + {{- $currentPage := . -}} + {{ range .Site.Menus.main -}} +
  • + {{ .Name }} +
  • + {{- end }} +
+ +``` + +## Missing Translations + +If a string does not have a translation for the current language, Hugo will use the value from the default language. If no default value is set, an empty string will be shown. + +While translating a Hugo website, it can be handy to have a visual indicator of missing translations. The [`enableMissingTranslationPlaceholders` configuration option][config] will flag all untranslated strings with the placeholder `[i18n] identifier`, where `identifier` is the id of the missing translation. + +{{% note %}} +Hugo will generate your website with these missing translation placeholders. It might not be suited for production environments. +{{% /note %}} + +For merging of content from other languages (i.e. missing content translations), see [lang.Merge](/functions/lang.merge/). + ++To track down missing translation strings, run Hugo with the `--i18n-warnings` flag: ++ ++``` ++ hugo --i18n-warnings | grep i18n ++i18n|MISSING_TRANSLATION|en|wordCount ++``` ++ +## Multilingual Themes support + +To support Multilingual mode in your themes, some considerations must be taken for the URLs in the templates.

Often, content authors are forced to add raw HTML (e.g., video ``) to Markdown content. We think this contradicts the beautiful simplicity of Markdown's syntax. + +Hugo created **shortcodes** to circumvent these limitations. + +A shortcode is a simple snippet inside a content file that Hugo will render using a predefined template. Note that shortcodes will not work in template files. If you need the type of drop-in functionality that shortcodes provide but in a template, you most likely want a [partial template][partials] instead. + +In addition to cleaner Markdown, shortcodes can be updated any time to reflect new classes, techniques, or standards. At the point of site generation, Hugo shortcodes will easily merge in your changes. You avoid a possibly complicated search and replace operation. + +## Use Shortcodes + +{{< youtube 2xkNJL4gJ9E >}} + +In your content files, a shortcode can be called by calling `{{%/* shortcodename parameters */%}}`. Shortcode parameters are space delimited, and parameters with internal spaces can be quoted. + +The first word in the shortcode declaration is always the name of the shortcode. Parameters follow the name. Depending upon how the shortcode is defined, the parameters may be named, positional, or both, although you can't mix parameter types in a single call. The format for named parameters models that of HTML with the format `name="value"`. + +Some shortcodes use or require closing shortcodes. Again like HTML, the opening and closing shortcodes match (name only) with the closing declaration, which is prepended with a slash. + +Here are two examples of paired shortcodes: + +``` +{{%/* mdshortcode */%}}Stuff to `process` in the *center*.{{%/* /mdshortcode */%}} +``` + +``` +{{}} A bunch of code here {{}} +``` + +The examples above use two different delimiters, the difference being the `%` character in the first and the `<>` characters in the second. + +### Shortcodes with Markdown + +The `%` character indicates that the shortcode's inner content---called in the [shortcode template][sctemps] with the [`.Inner` variable][scvars]---needs further processing by the page's rendering processor (i.e. markdown via Blackfriday). In the following example, Blackfriday would convert `**World**` to `World`: + +``` +{{%/* myshortcode */%}}Hello **World!**{{%/* /myshortcode */%}} +``` + +### Shortcodes Without Markdown + +The `<` character indicates that the shortcode's inner content does *not* need further rendering.

Hello World!

{{}} +``` + +### Nested Shortcodes + +You can call shortcodes within other shortcodes by creating your own templates that leverage the `.Parent` variable. `.Parent` allows you to check the context in which the shortcode is being called. See [Shortcode templates][sctemps]. + +## Use Hugo's Built-in Shortcodes + +Hugo ships with a set of predefined shortcodes that represent very common usage. These shortcodes are provided for author convenience and to keep your markdown content clean. + +### `figure` + +`figure` is an extension of the image syntax in markdown, which does not provide a shorthand for the more semantic [HTML5 `
` element][figureelement]. + +The `figure` shortcode can use the following named parameters: + +src +: URL of the image to be displayed. + +link +: If the image needs to be hyperlinked, URL of the destination. + +target +: Optional `target` attribute for the URL if `link` parameter is set. + +rel +: Optional `rel` attribute for the URL if `link` parameter is set. + +alt +: Alternate text for the image if the image cannot be displayed. + +title +: Image title. + +caption +: Image caption. + +class +: `class` attribute of the HTML `figure` tag. + +height +: `height` attribute of the image. + +width +: `width` attribute of the image. + +attr +: Image attribution text. + +attrlink +: If the attribution text needs to be hyperlinked, URL of the destination. + +#### Example `figure` Input + +{{< code file="figure-input-example.md" >}} +{{}} +{{< /code >}} + +#### Example `figure` Output + +{{< output file="figure-output-example.html" >}} +
