Pages organization

In Hugo, pages are the core of your site. Once it is configured, pages are definitely the added value to your documentation site.

Folders

Organize your site like any other Hugo project. Typically, you will have a content folder with all your pages.

content
├── level-one
│   ├── level-two
│   │   ├── level-three
│   │   │   ├── level-four
│   │   │   │   ├── _index.md       <-- /level-one/level-two/level-three/level-four

Create your project

The following steps are here to help you initialize your new website. If you don’t know Hugo at all, we strongly suggest you to train by following great documentation for beginners.

Hugo provides a new command to create a new website.

hugo new site <new_project>

The Relearn theme provides archetypes to help you create this kind of pages.

Frontmatter

Each Hugo page has to define a frontmatter.

Some Detailed Examples

Add Icon to a Menu Entry

In the page frontmatter, add a menuPre param to insert any HTML code before the menu label. The example below uses the GitHub icon.

+++
menuPre = "<i class='fab fa-github'></i> "
title = 'GitHub repo'
+++

---
menuPre: '<i class=''fab fa-github''></i> '
title: GitHub repo
---

{
   "menuPre": "\u003ci class='fab fa-github'\u003e\u003c/i\u003e ",
   "title": "GitHub repo"
}

Ordering Sibling Menu/Page Entries

Hugo provides a flexible way to handle order for your pages.

The simplest way is to set weight parameter to a number.

+++
title = 'My page'
weight = 5
+++

---
title: My page
weight: 5
---

{
   "title": "My page",
   "weight": 5
}

Using a Custom Title for Menu Entries

By default, the Relearn theme will use a page’s title attribute for the menu item.

But a page’s title has to be descriptive on its own while the menu is a hierarchy. Hugo adds the linkTitle parameter for that purpose:

For example (for a page named content/install/linux.md):

+++
linkTitle = 'Linux'
title = 'Install on Linux'
+++

---
linkTitle: Linux
title: Install on Linux
---

{
   "linkTitle": "Linux",
   "title": "Install on Linux"
}

Override Expand State Rules for Menu Entries

You can change how the theme expands menu entries on the side of the content with the alwaysopen setting on a per page basis. If alwaysopen=false for any given entry, its children will not be shown in the menu as long as it is not necessary for the sake of navigation.

The theme generates the menu based on the following rules:

• all parent entries of the active page including their siblings are shown regardless of any settings
• immediate children entries of the active page are shown regardless of any settings
• if not overridden, all other first level entries behave like they would have been given alwaysopen=false
• if not overridden, all other entries of levels besides the first behave like they would have been given alwaysopen=true
• all visible entries show their immediate children entries if alwaysopen=true; this proceeds recursively
• all remaining entries are not shown

You can see this feature in action on the example page for children shortcode and its children pages.

Disable Section Pages

You may want to structure your pages in a hierachical way but don’t want to generate pages for those sections? The theme got you covered.

To stay with the initial example: Suppose you want level-one appear in the sidebar but don’t want to generate a page for it. So the entry in the sidebar should not be clickable but should show an expander.

For this, open content/level-one/_index.md and add the following frontmatter

+++
collapsibleMenu = true

[_build]
  render = 'never'
+++

---
_build:
  render: never
collapsibleMenu: true
---

{
   "_build": {
      "render": "never"
   },
   "collapsibleMenu": true
}

Archetypes

Using the command: hugo new [relative new content path], you can start a content file with the date and title automatically set. While this is a welcome feature, active writers need more: archetypes. These are preconfigured skeleton pages with default frontmatter.

The Relearn theme defines some few archetypes of pages but you are free to define new ones to your liking. All can be used at any level of the documentation, the only difference being the layout of the content.

Predefined Archetypes

Home

A Home page is the starting page of your project. It’s best to have only one page of this kind in your project.

To create a home page, run the following command

hugo new --kind home _index.md

This leads to a file with the following content

+++
archetype = "home"
title = "{{ replace .Name "-" " " | title }}"
+++

Lorem Ipsum.

Chapter

A Chapter displays a page meant to be used as introduction for a set of child pages. Commonly, it contains a simple title and a catch line to define content that can be found below it.

To create a chapter page, run the following command

hugo new --kind chapter <name>/_index.md

This leads to a file with the following content

+++
archetype = "chapter"
title = "{{ replace .Name "-" " " | title }}"
weight = 1
+++

Lorem Ipsum.

The weight number will be used to generate the subtitle of the chapter page, set the number to a consecutive value starting at 1 for each new chapter level.

Default

A Default page is any other content page. If you set an unknown archetype in your frontmatter, this archetype will be used to generate the page.

To create a default page, run either one of the following commands

hugo new <chapter>/<name>/_index.md

or

hugo new <chapter>/<name>.md

This leads to a file with the following content

+++
title = "{{ replace .Name "-" " " | title }}"
+++

Lorem Ipsum.

Self defined Archetypes

If you are in need of further archetypes you can define your own or even redefine existing ones.

Template

Define a template file in your project at archetypes/<kind>.md and make sure it has at least the frontmatter parameter for that archetype like

+++
archetype = "<kind>"
+++

Afterwards you can generate new content files of that kind with the following command

hugo new --kind <kind> <name>/_index.md

Partials

To define how your archetypes are rendered, define corresponding partial files in your projects directory layouts/partials/archetypes/<kind>.

If you use an unknown archetype in your frontmatter, the default archetype will be used to generate the page.

Related to each archetype, several hook partial files in the form of <hook>.html can be given inside each archetype directory. If a partial for a specific hook is missing, no output is generated for this hook.

The following hooks are used:

Take a look at the existing archetypes of this theme to get an idea how to utilize it.

Output formats

Each hook file can be overridden of a specific output format. Eg. if you define a new output format PLAINTEXT in your hugo.toml, you can add a file layouts/partials/archetypes/default.plaintext.html to change the way how normal content is written for that output format.

Markdown syntax

Let’s face it: Writing content for the web is tiresome. WYSIWYG editors help alleviate this task, but they generally result in horrible code, or worse yet, ugly web pages.

Markdown is a better way to write HTML, without all the complexities and ugliness that usually accompanies it.

Some of the key benefits are:

1. Markdown is simple to learn, with minimal extra characters so it’s also quicker to write content.
2. Less chance of errors when writing in Markdown.
3. Produces valid HTML output.
4. Keeps the content and the visual display separate, so you cannot mess up the look of your site.
5. Write in any text editor or Markdown application you like.
6. Markdown is a joy to use!

John Gruber, the author of Markdown, puts it like this:

The overriding design goal for Markdown’s formatting syntax is to make it as readable as possible. The idea is that a Markdown-formatted document should be publishable as-is, as plain text, without looking like it’s been marked up with tags or formatting instructions. While Markdown’s syntax has been influenced by several existing text-to-HTML filters, the single biggest source of inspiration for Markdown’s syntax is the format of plain text email. John Gruber

Without further delay, let us go over the main elements of Markdown and what the resulting HTML looks like:

Paragraphs

In Markdown your content usually spans the whole available document width. This is called a block. Blocks are always separated by whitespace to their adjacent blocks in the resulting document.

Any text not starting with a special sign is written as normal, plain text paragraph block and must be separated to its adjacent blocks by empty lines.

Lorem ipsum dolor sit amet, graecis denique ei vel, at duo primis mandamus.

Et legere ocurreret pri, animal tacimates complectitur ad cum. Cu eum inermis inimicus efficiendi. Labore officiis his ex, soluta officiis concludaturque ei qui, vide sensibus vim ad.

Headings

A good idea is to structure your content using headings and subheadings. HTML-headings from h1 through h6 are constructed with a # for each level.

In Hugo you usually don’t use h1 as this is generated by your theme and you should only have one such element in a document.

# h1 Heading

## h2 Heading

### h3 Heading

#### h4 Heading

##### h5 Heading

###### h6 Heading

Horizontal Rules

To further structure your content you can add horizontal rules. They create a “thematic break” between paragraph blocks. In Markdown, you can create it with three consecutive dashes ---.

Lorem ipsum dolor sit amet, graecis denique ei vel, at duo primis mandamus.

---

Et legere ocurreret pri, animal tacimates complectitur ad cum. Cu eum inermis inimicus efficiendi. Labore officiis his ex, soluta officiis concludaturque ei qui, vide sensibus vim ad.

Text Markers

Bold

You can show importance of a snippet of text with a heavier font-weight by enclosing it with two asterisks **.

I am rendered with **bold text**

Italics

You can emphasize a snippet of text with italics by enclosing it with underscores _.

I am rendered with _italicized text_

Strikethrough

In GFM (GitHub Flavored Markdown) you can do strikethroughs by enclosing text with two tildes ~~.

~~Strike through this text~~

Text substitution

This Markdown dialect supports an extension to combine multiple punctuation characters to single typographic entities. This will only be applied to text outside of code blocks or inline code.

Double quotes `"` and single quotes `'` of enclosed text are replaced by **"double curly quotes"** and **'single curly quotes'**.

Double dashes `--` and triple dashes `---` are replaced by en-dash **--** and em-dash **---** entities.

Double arrows pointing left `<<` or right `>>` are replaced by arrow **<<** and **>>** entities.

Three consecutive dots `...` are replaced by an ellipsis **...** entity.

Lists

Unordered

You can write a list of items in which the order of the items does not explicitly matter.

It is possible to nest lists by indenting an item for the next sublevel.

You may use any of -, * or + to denote bullets for each list item but should not switch between those symbols inside one whole list.

- Lorem ipsum dolor sit amet
- Consectetur adipiscing elit
  - Vestibulum laoreet porttitor sem
  - Ac tristique libero volutpat at
- Nulla volutpat aliquam velit
  - Phasellus iaculis neque
  - Purus sodales ultricies
- Faucibus porta lacus fringilla vel

Ordered

You can create a list of items in which the order of items does explicitly matter.

It is possible to nest lists by indenting an item for the next sublevel.

Markdown will automatically number each of your items consecutively. This means, the order number you are providing is irrelevant.

1. Lorem ipsum dolor sit amet
3. Consectetur adipiscing elit
    1. Integer molestie lorem at massa
    7. Facilisis in pretium nisl aliquet
99. Nulla volutpat aliquam velit
    1. Faucibus porta lacus fringilla vel
    1. Aenean sit amet erat nunc
17. Eget porttitor lorem

Tasks

In GFM (GitHub Flavored Markdown) you can add task lists resulting in checked or unchecked non-clickable items

- [x] Basic Test
- [ ] More Tests
  - [x] View
  - [x] Hear
  - [ ] Smell

Definitions

This Markdown dialect supports an extension to add definition lists. Definition lists are made of terms and definitions of these terms, much like in a dictionary.

A definition list in Markdown Extra is made of a single-line term followed by a colon and the definition for that term. You can also associate more than one term to a definition.

If you add empty lines around the definition terms, additional vertical space will be generated. Also multiple paragraphs are possible

Apple
: Pomaceous fruit of plants of the genus Malus in the family Rosaceae.
: An American computer company.

Orange
: The fruit of an evergreen tree of the genus Citrus.

  You can make juice out of it.
: A telecommunication company.

  You can't make juice out of it.

Code

Inline Code

Inline snippets of code can be wrapped with backticks `.

In this example, `<div></div>` is marked as code.

Indented Code Block

A simple code block can be generated by indenting several lines of code by at least two spaces.

Be impressed by my advanced code:

    // Some comments
    line 1 of code
    line 2 of code
    line 3 of code

// Some comments
line 1 of code
line 2 of code
line 3 of code

Fenced Code Block

If you want to gain more control of your code block you can enclose your code by at least three backticks ``` a so called fence.

In GFM (GitHub Flavored Markdown) you can also add a language specifier directly after the opening fence, ```js, and syntax highlighting will automatically be applied according to the selected language in the rendered HTML.

See Code Highlighting for additional documentation.

Tables

In GFM (GitHub Flavored Markdown) you can create tables by adding pipes as dividers between each cell, and by adding a line of dashes (also separated by bars) beneath the header. Note that the pipes do not need to be vertically aligned.

| Option | Description |
|--------|-------------|
| data   | path to data files to supply the data that will be passed into templates. |
| engine | engine to be used for processing templates. Handlebars is the default. |
| ext    | extension to be used for dest files. |

Aligned Columns

Adding a colon on the left and/or right side of the dashes below any heading will align the text for that column accordingly.

| Option | Number | Description |
|-------:|:------:|:------------|
| data   | 1      | path to data files to supply the data that will be passed into templates. |
| engine | 2      | engine to be used for processing templates. Handlebars is the default. |
| ext    | 3      | extension to be used for dest files. |

Blockquotes

For quoting blocks of content from another source within your document add > before any text you want to quote.

Blockquotes can also be nested.

> Donec massa lacus, ultricies a ullamcorper in, fermentum sed augue. Nunc augue augue, aliquam non hendrerit ac, commodo vel nisi.
>
> > Sed adipiscing elit vitae augue consectetur a gravida nunc vehicula. Donec auctor odio non est accumsan facilisis. Aliquam id turpis in dolor tincidunt mollis ac eu diam.
>
> Mauris sit amet ligula egestas, feugiat metus tincidunt, luctus libero. Donec congue finibus tempor. Vestibulum aliquet sollicitudin erat, ut aliquet purus posuere luctus.

Links

Autolink

In GFM (GitHub Flavored Markdown) absolute URLs will automatically be converted into a link.

This is a link to https://example.com.

Basic Link

You can explicitly define links in case you want to use non-absolute URLs or want to give different text.

[Assemble](http://assemble.io)

Link with Tooltip

For even further information, you can add an additional text, displayed in a tooltip on hovering over the link.

[Upstage](https://github.com/upstage/ "Visit Upstage!")

Link References

Links can be simplyfied for recurring reuse by using a reference ID to later define the URL location. This simplyfies writing if you want to use a link more than once in a document.

[Example][somelinkID]

[somelinkID]: https://example.com "Go to example domain"

Footnotes

Footnotes work mostly like reference-style links. A footnote is made of two things, a marker in the text that will become a superscript number and a footnote definition that will be placed in a list of footnotes.

Usually the list of footnotes will be shown at the end of your document. If we use a footnote in a notice box it will instead be listed at the end of its box.

Footnotes can contain block elements, which means that you can put multiple paragraphs, lists, blockquotes and so on in a footnote. It works the same as for list items, just indent the following paragraphs by four spaces in the footnote definition.

That's some text with a footnote[^1]

[^1]: And that's the footnote.

That's some more text with a footnote.[^someid]

[^someid]:
    Anything of interest goes here.

    Blue light glows blue.

Images

Basic Images

Images have a similar syntax to links but include a preceding exclamation mark.

![Spock](https://octodex.github.com/images/spocktocat.png)

Image with Tooltip

Like links, images can also be given a tooltip.

![Picard](https://octodex.github.com/images/jean-luc-picat.jpg "Jean Luc Picard")

Image References

Images can also be linked by reference ID to later define the URL location. This simplyfies writing if you want to use an image more than once in a document.

![La Forge][laforge]

[laforge]: https://octodex.github.com/images/trekkie.jpg "Geordi La Forge"

Image Effects

This theme allows additional non-standard formatting by setting query parameter at the end of the image URL. The default behavior is configurable thru your hugo.toml or frontmatter parameter.

Resizing

Add query parameter width and/or height to the link image to resize the image. Values are CSS values (default is auto).

![Minion](https://octodex.github.com/images/minion.png?width=20vw)

![Minion](https://octodex.github.com/images/minion.png?height=50px)

![Minion](https://octodex.github.com/images/minion.png?height=50px&width=40vw)

CSS Classes

Add a query parameter classes to the link image to add CSS classes. Add some of the predefined values or even define your own in your CSS.

Shadow

![Spidertocat](https://octodex.github.com/images/spidertocat.png?classes=shadow)

Border

![DrOctocat](https://octodex.github.com/images/droctocat.png?classes=border)

Left

![Supertocat](https://octodex.github.com/images/okal-eltocat.jpg?classes=left)

Right

![Riddlocat](https://octodex.github.com/images/riddlocat.jpg?classes=right)

Inline

![Spidertocat](https://octodex.github.com/images/spidertocat.png?classes=inline)

![Supertocat](https://octodex.github.com/images/okal-eltocat.jpg?classes=inline)
![Riddlocat](https://octodex.github.com/images/riddlocat.jpg?classes=inline)

Combination

![X-tocat](https://octodex.github.com/images/xtocat.jpg?classes=shadow,border,left)

Lightbox

Add the query parameter lightbox=false to the image link to disable the lightbox.

![Homercat](https://octodex.github.com/images/homercat.png?lightbox=false)

[![Homercat](https://octodex.github.com/images/homercat.png?lightbox=false)](https://octodex.github.com/#homercat)

Image Effects

The theme supports non-standard image effects.

As described, you can add this to the URL query parameter, but this may be cumbersome to do it consistently for the whole page.

Instead, you can configure the defaults in your hugo.toml aswell as overriding these default in the pages frontmatter.

Explicitly set URL query parameter will override the defaults in effect for a page.

Without any settings in your hugo.toml this defaults to

[params]
  [params.imageEffects]
    border = false
    lightbox = true
    shadow = false

params:
  imageEffects:
    border: false
    lightbox: true
    shadow: false

{
   "params": {
      "imageEffects": {
         "border": false,
         "lightbox": true,
         "shadow": false
      }
   }
}

This can be overridden in a pages frontmatter by eg.

+++
[imageEffects]
  border = true
+++

---
imageEffects:
  border: true
---

{
   "imageEffects": {
      "border": true
   }
}

Or by explicitly override settings by URL query parameter

![Minion](https://octodex.github.com/images/minion.png?lightbox=false&bg-white=true)

The settings applied to the above image would be

bg-white = true
border = true
lightbox = false
shadow = false

bg-white: true
border: true
lightbox: false
shadow: false

{
   "bg-white": true,
   "border": true,
   "lightbox": false,
   "shadow": false
}

This ends up in the following HTML where the parameter are converted to CSS classes.

<img src="https://octodex.github.com/images/minion.png?lightbox=false&bg-white=true" alt="Minion" class="bg-white border nolightbox noshadow">

Extending

As you can see in the above example, the bg-white parameter is not initially supported in the themes default settings. Nevertheless you are free to define arbitrary parameter by just adding them to the URL query parameter or set them in your hugo.toml or pages frontmatter.

Menu extra shortcuts

You can define additional menu entries or shortcuts in the navigation menu without any link to content.

Basic configuration

Edit the website configuration hugo.toml and add a [[menu.shortcuts]] entry for each link your want to add.

Example from the current website:

[menu]
[[menu.shortcuts]]
    identifier = 'ds'
    name = "<i class='fab fa-fw fa-github'></i> GitHub repo"
    url = 'https://github.com/McShelby/hugo-theme-relearn'
    weight = 10

[[menu.shortcuts]]
    name = "<i class='fas fa-fw fa-camera'></i> Showcases"
    url = 'showcase/'
    weight = 11

[[menu.shortcuts]]
    identifier = 'hugodoc'
    name = "<i class='fas fa-fw fa-bookmark'></i> Hugo Documentation"
    url = 'https://gohugo.io/'
    weight = 20

[[menu.shortcuts]]
    name = "<i class='fas fa-fw fa-bullhorn'></i> Credits"
    url = 'more/credits/'
    weight = 30

[[menu.shortcuts]]
    name = "<i class='fas fa-fw fa-tags'></i> Tags"
    url = 'tags/'
    weight = 40

menu:
  shortcuts:
  - identifier: ds
    name: <i class='fab fa-fw fa-github'></i> GitHub repo
    url: https://github.com/McShelby/hugo-theme-relearn
    weight: 10
  - name: <i class='fas fa-fw fa-camera'></i> Showcases
    url: showcase/
    weight: 11
  - identifier: hugodoc
    name: <i class='fas fa-fw fa-bookmark'></i> Hugo Documentation
    url: https://gohugo.io/
    weight: 20
  - name: <i class='fas fa-fw fa-bullhorn'></i> Credits
    url: more/credits/
    weight: 30
  - name: <i class='fas fa-fw fa-tags'></i> Tags
    url: tags/
    weight: 40

{
   "menu": {
      "shortcuts": [
         {
            "identifier": "ds",
            "name": "\u003ci class='fab fa-fw fa-github'\u003e\u003c/i\u003e GitHub repo",
            "url": "https://github.com/McShelby/hugo-theme-relearn",
            "weight": 10
         },
         {
            "name": "\u003ci class='fas fa-fw fa-camera'\u003e\u003c/i\u003e Showcases",
            "url": "showcase/",
            "weight": 11
         },
         {
            "identifier": "hugodoc",
            "name": "\u003ci class='fas fa-fw fa-bookmark'\u003e\u003c/i\u003e Hugo Documentation",
            "url": "https://gohugo.io/",
            "weight": 20
         },
         {
            "name": "\u003ci class='fas fa-fw fa-bullhorn'\u003e\u003c/i\u003e Credits",
            "url": "more/credits/",
            "weight": 30
         },
         {
            "name": "\u003ci class='fas fa-fw fa-tags'\u003e\u003c/i\u003e Tags",
            "url": "tags/",
            "weight": 40
         }
      ]
   }
}

By default, shortcuts are preceded by a title. This title can be disabled by setting disableShortcutsTitle=true. However, if you want to keep the title but change its value, it can be overridden by changing your local i18n translation string configuration.

For example, in your local i18n/en.toml file, add the following content

[Shortcuts-Title]
other = "<Your value>"

Configuration for Multilingual mode

When using a multilingual website, you can set different menus for each language. In the hugo.toml file, prefix your menu configuration by Languages.<language-id>.

Example from the current website:

[languages]
  [languages.en]
    languageName = 'English'
    title = 'Hugo Relearn Theme'
    weight = 1

    [languages.en.menu]
[[languages.en.menu.shortcuts]]
        identifier = 'ds'
        name = "<i class='fab fa-fw fa-github'></i> GitHub repo"
        url = 'https://github.com/McShelby/hugo-theme-relearn'
        weight = 10

[[languages.en.menu.shortcuts]]
        name = "<i class='fas fa-fw fa-camera'></i> Showcases"
        pageRef = 'showcase/'
        weight = 11

[[languages.en.menu.shortcuts]]
        identifier = 'hugodoc'
        name = "<i class='fas fa-fw fa-bookmark'></i> Hugo Documentation"
        url = 'https://gohugo.io/'
        weight = 20

[[languages.en.menu.shortcuts]]
        name = "<i class='fas fa-fw fa-bullhorn'></i> Credits"
        pageRef = 'more/credits/'
        weight = 30

[[languages.en.menu.shortcuts]]
        name = "<i class='fas fa-fw fa-tags'></i> Tags"
        pageRef = 'tags/'
        weight = 40

    [languages.en.params]
      landingPageName = "<i class='fas fa-home'></i> Home"

  [languages.pir]
    languageName = 'Arrr! Pirrrates'
    title = "Cap'n Hugo Relearrrn Theme"
    weight = 1

    [languages.pir.menu]
[[languages.pir.menu.shortcuts]]
        identifier = 'ds'
        name = "<i class='fab fa-fw fa-github'></i> GitHub repo"
        url = 'https://github.com/McShelby/hugo-theme-relearn'

Shortcuts to pages inside of your project

If you have shortcuts to pages inside of your project and you don’t want them to show up in page menu section, you have two choices:

1. Make the page file for the shortcut a headless branch bundle (contained in its own subdirectory and called _index.md) and add the following frontmatter configuration to the file (see exampleSite’s content/showcase/_index.en.md). This causes its content to not be ontained in the sitemap.

   ​

   toml yaml json

   +++
   title = 'Showcase'
   
   [_build]
     list = 'never'
     publishResources = true
     render = 'always'
   +++

   ---
   _build:
     list: never
     publishResources: true
     render: always
   title: Showcase
   ---

   {
      "_build": {
         "list": "never",
         "publishResources": true,
         "render": "always"
      },
      "title": "Showcase"
   }

2. Store the page file for the shortcut below a parent headless branch bundle and add the following frontmatter to he parent (see exampleSite’s content/more/_index.en.md). Don’t give this page a title as this will cause it to be shown in the breadcrumbs - a thing you most likely don’t want.

   In this case, the file itself can be a branch bundle, leaf bundle or simple page (see exampleSite’s content/more/credits.en.md). This causes its content to be contained in the sitemap.

   ​

   toml yaml json

   +++
   title = 'Credits'
   +++

   ---
   title: Credits
   ---

   {
      "title": "Credits"
   }

Multilingual and i18n

The Relearn theme is fully compatible with Hugo multilingual mode.

• Available languages: Arabic, Simplified Chinese, Traditional Chinese, Czech, Dutch, English, Finnish, French, German, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Swahili, Turkish, Vietnamese. Feel free to contribute!
• Full 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 hugo.toml file.

For example with current English and Piratized English website.

defaultContentLanguage = 'en'

[languages]
  [languages.en]
    languageName = 'English'
    title = 'Hugo Relearn Theme'
    weight = 1

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

defaultContentLanguage: en
languages:
  en:
    languageName: English
    title: Hugo Relearn Theme
    weight: 1
  pir:
    languageName: Arrr! Pirrrates
    title: Cap'n Hugo Relearrrn Theme
    weight: 2

{
   "defaultContentLanguage": "en",
   "languages": {
      "en": {
         "languageName": "English",
         "title": "Hugo Relearn Theme",
         "weight": 1
      },
      "pir": {
         "languageName": "Arrr! Pirrrates",
         "title": "Cap'n Hugo Relearrrn Theme",
         "weight": 2
      }
   }
}

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

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.

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 hugo.toml to broaden search.

[params]
  additionalContentLanguage = ['en']

params:
  additionalContentLanguage:
  - en

{
   "params": {
      "additionalContentLanguage": [
         "en"
      ]
   }
}

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

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 hugo.toml

[params]
  disableLanguageSwitchingButton = true

params:
  disableLanguageSwitchingButton: true

{
   "params": {
      "disableLanguageSwitchingButton": true
   }
}

Taxonomy

The Relearn theme supports Hugo’s default taxonomies tag and category out of the box.

Configuration

Just add tags and/or categories to any page. They can be given as a single string or an array of strings.

+++
categories = ['taxonomy', 'content']
tags = 'tutorial'
title = 'Taxonomy'
+++

---
categories:
- taxonomy
- content
tags: tutorial
title: Taxonomy
---

{
   "categories": [
      "taxonomy",
      "content"
   ],
   "tags": "tutorial",
   "title": "Taxonomy"
}

Behavior

The tags are displayed at the top of the page in alphabetical order.

The categories are displayed at the bottom of the page in alphabetical order in the default implementation of the theme but can be customized by providing your own content-footer.html partial.

Each item is a link to a taxonomy page displaying all the articles with the given term.

List all the tags

In the hugo.toml file you can add a shortcut to display all the tags and categories

[menu]
[[menu.shortcuts]]
    name = "<i class='fas fa-tags'></i> Tags"
    url = '/tags'

[[menu.shortcuts]]
    name = "<i class='fas fa-layer-group'></i> Categories"
    url = '/categories'

menu:
  shortcuts:
  - name: <i class='fas fa-tags'></i> Tags
    url: /tags
  - name: <i class='fas fa-layer-group'></i> Categories
    url: /categories

{
   "menu": {
      "shortcuts": [
         {
            "name": "\u003ci class='fas fa-tags'\u003e\u003c/i\u003e Tags",
            "url": "/tags"
         },
         {
            "name": "\u003ci class='fas fa-layer-group'\u003e\u003c/i\u003e Categories",
            "url": "/categories"
         }
      ]
   }
}

Customization

If you define custom taxonomies and want to display a list of them somewhere on your page (often in the layouts/partials/content-footer.html) you can call a partial that does the job for you:

{{ partial "term-list.html" (dict
  "page" .
  "taxonomy" "categories"
  "icon" "layer-group"
) }}
