What's new

This document shows you what’s new in the latest release. For a detailed list of changes, see the history page.

Breaking: A change that requires action by you after upgrading to assure the site is still functional.

Change: A change in default behavior. This may requires action by you / may or may not be revertable by configuration.

New: Marks new behavior you might find interesting or comes configurable.

4.2.0

• Breaking: The second parameter for the include shortcode was switched in meaning and was renamed from showfirstheading to hidefirstheading. If you haven’t used this parameter in your shortcode, the default behavior hasn’t changed and you don’t need to change anything.

  If you’ve used the second boolean parameter, you have to rename it and invert its value to achive the same behavior.

• Change: Previously, if the tabs shortcode could not find a tab item because, the tabs ended up empty. Now the first tab is selected instead.

• Change: The landingPageURL was removed from config.toml. You can savely remove this aswell from your configuration as it is not used anymore. The theme will detect the landing page URL automatically.

• New: All shortcodes can now be also called from your partials. Examples for this are added to the documentation of each shortcode.

4.1.0

• New: While fixing issues with the search functionality for non latin languages, you can now configure to have multiple languages on a single page.

4.0.0

• Breaking: The custom_css config parameter was removed from the configuration. If used in an existing installation, it can be achieved by overriding the custom-header.html template in a much more generic manner.

• Breaking: Because anchor hover color was not configurable without introducing more complexitity to the variant stylesheets, we decided to remove --MAIN-ANCHOR-color instead. You don’t need to change anything in your custom color stylesheet as the anchors now get their colors from --MAIN-LINK-color and --MAIN-ANCHOR-HOVER-color respectivley.

• New: All shortcodes now support named parameter. The positional parameter are still supported but will not be enhanced with new features, so you don’t need to change anything in your installation.

  This applies to expand, include, notice and siteparam.

• New: The button shortcode received some love and now has a parameter for the color style similar to other shortcodes.

• New: New colors --PRIMARY-color and --SECONDARY-color were added to provide easier modification of your custom style. Shortcodes with a color style can now have primary or secondary as additional values.

  These two colors are the default for other, more specific color variables. You don’t need to change anything in your existing custom color stylesheets as those variables get reasonable default values.

• New: The documentation for all shortcodes were revised.

3.4.0

• Breaking: If you had previously overwritten the custom-footer.html partial to add visual elements below the content of your page, you have to move this content to the new partial content-footer.html. custom-footer.html was never meant to contain HTML other than additional styles and JavaScript.

• New: If you prefer expandable/collapsible menu items, you can now set collapsibleMenu=true in your config.toml. This will add arrows to all menu items that contain sub menus. The menu will expand/collapse without navigation if you click on an arrow.

• New: You can activate print support in your config.toml to add the capability to print whole chapters or even the complete site.

• New: Translation for Traditional Chinese.

3.3.0

• New: Introduction of new CSS variables to set the font. The theme distinguishs between --MAIN-font for all content text and --CODE-font for inline or block code. There are additional overrides for all headings. See the theme variant generator of the exampleSite for all available variables.

• New: The new shortcode swagger is available to include a UI for REST OpenAPI Specifications. See the documentation for available features. This feature will not work with Internet Explorer 11.

3.2.0

• Change: In this release the Mermaid JavaScript library will only be loaded on demand if the page contains a Mermaid shortcode or is using Mermaid codefences. This changes the behavior of disableMermaid config option as follows: If a Mermaid shortcode or codefence is found, the option will be ignored and Mermaid will be loaded regardlessly.

  The option is still useful in case you are using scripting to set up your graph. In this case no shortcode or codefence is involved and the library is not loaded by default. In this case you can set disableMermaid=false in your frontmatter to force the library to be loaded. See the theme variant generator of the exampleSite for an example.

  This change requires at least Hugo 0.93.0 to be used. The minimum requirement will be reported during build on the console if not met.

• New: Additional color variant variable --MERMAID-theme to set the variant’s Mermaid theme. This causes the Mermaid theme to switch with the color variant if it defers from the setting of the formerly selected color variant.

3.1.0

• New: attachment and notice shortcodes have a new parameter to override the default icon. Allowed values are all Font Awesome 5 Free icons.

3.0.0

• Breaking: We made changes to the menu footer. If you have your menu-footer.html partial overridden, you may have to review the styling (eg. margins/paddings) in your partial. For a reference take a look into the menu-footer.html partial that is coming with the exampleSite.

  This change was made to allow your own menu footer to be placed right after the so called prefooter that comes with the theme (containing the language switch and Clear history functionality).

• Breaking: We have changed the default colors from the original Learn theme (the purple menu header) to the Relearn defaults (the light green menu header) as used in the official documentation.

  This change will only affect your installation if you’ve not set the themeVariant parameter in your config.toml. If you still want to use the Learn color variant, you have to explicitly set themeVariant="learn" in your config.toml.

  Note, that this will also affect your site if viewed with Internet Explorer 11 but in this case it can not be reconfigured as Internet Explorer does not support CSS variables.

• Change: Due to a bug, that we couldn’t fix in a general manner for color variants, we decided to remove --MENU-SEARCH-BOX-ICONS-color and introduced --MENU-SEARCH-color instead. You don’t need to change anything in your custom color stylesheet as the old name will be used as a fallback.

• Change: For consistency reasons, we renamed --MENU-SEARCH-BOX-color to --MENU-SEARCH-BORDER-color. You don’t need to change anything in your custom color stylesheet as the old name will be used as a fallback.

• New: With this release you are now capable to define your own dark mode variants.

  To make this possible, we have introduced a lot more color variables you can use in your color variants. Your old variants will still work and don’t need to be changed as apropriate fallback values are used by the theme. Nevertheless, the new colors allow for much more customization.

  To see what’s now possible, see the new variants relearn-dark and neon that are coming with this release.

• New: To make the creation of new variants easier for you, we’ve added a new interactive theme variant generator. This feature will not work with Internet Explorer 11.

• New: You can now configure multiple color variants in your config.toml. In this case, the first variant is the default chosen on first view and a variant switch will be shown in the menu footer. See the documentation for configuration.

  Note, that the new variant switch will not work with Internet Explorer 11 as it does not support CSS variables. Therefore, the variant switcher will not be displayed with Internet Explorer 11.

2.9.0

• Breaking: This release removes the themes implementation of ref/relref in favor for Hugos standard implementation. This is because of inconsistencies with the themes implementation. In advantage, your project becomes standard complient and exchanging this theme in your project to some other theme will be effortless.

  In a standard complient form you must not link to the *.md file but to its logical name. You’ll see, referencing other pages becomes much easier. All three types result in the same reference:

  Type	Non-Standard	Standard
  Branch bundle	basics/configuration/_index.md	basics/configuration
  Leaf bundle	basics/configuration/index.md	basics/configuration
  Page	basics/configuration.md	basics/configuration

  If you’ve linked from a page of one language to a page of another language, conversion is a bit more difficult but Hugo got you covered as well.

  Also, the old themes implementation allowed refs to non-existing content. This will cause Hugos implementation to show the error below and abort the generation. If your project relies on this old behavior, you can reconfigure the error handling of Hugos implementation.

  In the best case your usage of the old implementation is already standard complient and you don’t need to change anything. You’ll notice this very easily once you’ve started hugo server after an upgrade and no errors are written to the console.

  You may see errors on the console after the update in the form:

  ERROR 2021/11/19 22:29:10 [en] REF_NOT_FOUND: Ref "basics/configuration/_index.md": "hugo-theme-relearn\exampleSite\content\_index.en.md:19:22": page not found
  

  In this case, you must apply one of two options:

  1. Copy the old implementation files theme/hugo-theme-relearn/layouts/shortcode/ref.html and theme/hugo-theme-relearn/layouts/shortcode/relref.html to your own projects layouts/shortcode/ref.html and layouts/shortcode/relref.html respectively. This is not recommended as your project will still rely on non-standard behavior afterwards.

  2. Start up a text editor with regular expression support for search and replace. Apply the following conversions in the given order on all *.md files. This is the recommended choice.

  Type	Search	Replace by
  Branch bundle	(ref\s+"[^"]*)/_index\.md"	$1"
  Leaf bundle	(ref\s+"[^"]*)/index\.md"	$1"
  Page	(ref\s+"[^"]*)\.md"	$1"

2.8.0

• Change: Although never officially documented, this release removes the font Novacento/Novecento. If you use it in an overwritten CSS please replace it with Work Sans. This change was necessary as Novacento did not provide all Latin special characters and lead to mixed styled character text eg. for czech.

• New: The theme now supports favicons served from static/images/ named as favicon or logo in SVG, PNG or ICO format out of the box. An overridden partial layouts/partials/favicon.html may not be necessary anymore in most cases.

• New: You can hide the table of contents menu for the whole site by setting the disableToc option in your config.toml. For an example see the example configuration.

2.7.0

• New: Optional second parameter for notice shortcode to set title in box header.

2.6.0

• New: Your site can now be served from a subfolder if you set baseURL and canonifyURLs=true in your config.toml. See the documentation for a detailed example.

2.5.0

• Change: New colors --CODE-BLOCK-color and --CODE-BLOCK-BG-color were added to provide a fallback for Hugos syntax highlightning in case guessSyntax=true is set. Ideally the colors are set to the same values as the ones from your chosen chroma style.

2.4.0

• Change: Creation of customized stylesheets was simplified down to only contain the CSS variables. Everything else can and should be deleted from your custom stylesheet to assure everything works fine. For the predefined stylesheet variants, this change is already included.

• New: Hidden pages are displayed by default in their according tags page. You can now turn off this behavior by setting disableTagHiddenPages=true in your config.toml.

• New: You can define the expansion state of your menus for the whole site by setting the alwaysopen option in your config.toml. Please see further documentation for possible values and default behavior.

• New: New frontmatter ordersectionsby option to change immediate children sorting in menu and children shortcode. Possible values are title or weight.

• New: Alternate content of a page is now advertised in the HTML meta tags. See Hugo documentation.

2.3.0

• New: Showcase multilanguage features by provding a documentation translation “fer us pirrrates”. There will be no other translations besides the original English one and the Pirates one due to maintenance constraints.

2.2.0

• New: Hidden pages are displayed by default in the sitemap generated by Hugo and are therefore visible for search engine indexing. You can now turn off this behavior by setting disableSeoHiddenPages=true in your config.toml.

2.1.0

• Change: In case the site’s structure contains addional *.md files not part of the site (eg files that are meant to be included by site pages - see CHANGELOG.md in the exampleSite), they will now be ignored by the search.

• New: Hidden pages are indexed for the site search by default. You can now turn off this behavior by setting disableSearchHiddenPages=true in your config.toml.

• New: If a search term is found in an expand shortcode, the expand will be opened.

• New: The menu will scroll the active item into view on load.

2.0.0

• Change: Syntaxhighlightning was switched to the built in Hugo mechanism. You may need to configure a new stylesheet or decide to roll you own as described on in the Hugo documentation

• Change: In the predefined stylesheets there was a typo and --MENU-HOME-LINK-HOVERED-color must be changed to --MENU-HOME-LINK-HOVER-color. You don’t need to change anything in your custom color stylesheet as the old name will be used as a fallback.

• Change: --MENU-HOME-LINK-color and --MENU-HOME-LINK-HOVER-color were missing in the documentation. You should add them to your custom stylesheets if you want to override the defaults.

• Change: Arrow navigation and children shortcode were ignoring setting for ordersectionsby. This is now changed and may result in different sorting order of your sub pages.

• Change: If hidden pages are accessed directly by typing their URL, they will be exposed in the menu.

• Change: A page without a title will be treated as hidden=true.

• New: You can define the expansion state of your menus in the frontmatter. Please see further documentation for possible values and default behavior.

• New: New partials for defining pre/post content for menu items and the content. See documentation for further reading.

• New: Shortcode children with new parameter containerstyle.

• New: New shortcode include to include arbitrary file content into a page.

1.2.0

• New: Shortcode expand with new parameter to open on page load.

1.1.0

• New: Mermaid config options can be set in config.toml.

1.0.0

• New: Initial fork of the Learn theme based on Learn 2.5.0 on 2021-07-01. This introduces no new features besides a global rename to Relearn and a new logo. For the reasons behind forking the Learn theme, see this comment in the Learn issues.

Requirements

Thanks to the simplicity of Hugo, this page is as empty as this theme needs requirements.

Just download latest version of Hugo binary for your OS (Windows, Linux, Mac) : it’s that simple.

Installation

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

Create your project

Hugo provides a new command to create a new website.

hugo new site <new_project>

Install the theme

Install the Relearn theme by following this documentation

This theme’s repository is: https://github.com/McShelby/hugo-theme-relearn.git

Alternatively, you can download the theme as .zip file and extract it in the themes directory

Basic configuration

When building the website, you can set a theme by using --theme option. However, we suggest you modify the configuration file (config.toml) and set the theme as the default. You can also add the [outputs] section to enable the search functionality.

# Change the default theme to be use when building the site with Hugo
theme = "hugo-theme-relearn"

# For search functionality
[outputs]
home = [ "HTML", "RSS", "JSON"]

Create your first chapter page

Chapters are pages that contain other child pages. It has a special layout style and usually just contains a chapter name, the title and a brief abstract of the section.

### Chapter 1

# Basics

Discover what this Hugo theme is all about and the core concepts behind it.

renders as

The Relearn theme provides archetypes to create skeletons for your website. Begin by creating your first chapter page with the following command

hugo new --kind chapter basics/_index.md

By opening the given file, you should see the property chapter=true on top, meaning this page is a chapter.

By default all chapters and pages are created as a draft. If you want to render these pages, remove the property draft: true from the metadata.

Create your first content pages

Then, create content pages inside the previously created chapter. Here are two ways to create content in the chapter:

hugo new basics/first-content.md
hugo new basics/second-content/_index.md

Feel free to edit those files by adding some sample content and replacing the title value in the beginning of the files.

Launching the website locally

Launch by using the following command:

hugo serve

Go to http://localhost:1313

You should notice three things:

1. You have a left-side Basics menu, containing two submenus with names equal to the title properties in the previously created files.
2. The home page explains how to customize it by following the instructions.
3. When you run hugo serve, when the contents of the files change, the page automatically refreshes with the changes. Neat!

Build the website

When your site is ready to deploy, run the following command:

hugo

A public folder will be generated, containing all static content and assets for your website. It can now be deployed on any web server.

Configuration

Global site parameters

On top of Hugo global configuration, the Relearn theme lets you define the following parameters in your config.toml (here, values are default).

Note that some of these parameters are explained in details in other sections of this documentation.

[params]
  # This controls whether submenus will be expanded (true), or collapsed (false) in the
  # menu; if no setting is given, the first menu level is set to false, all others to true;
  # this can be overridden in the pages frontmatter
  alwaysopen = true
  # Prefix URL to edit current page. Will display an "Edit" button on top right hand corner of every page.
  # Useful to give opportunity to people to create merge request for your doc.
  # See the config.toml file from this documentation site to have an example.
  editURL = ""
  # Author of the site, will be used in meta information
  author = ""
  # Description of the site, will be used in meta information
  description = ""
  # Shows a checkmark for visited pages on the menu
  showVisitedLinks = false
  # Disable search function. It will hide search bar
  disableSearch = false
  # Disable search in hidden pages, otherwise they will be shown in search box
  disableSearchHiddenPages = false
  # Disables hidden pages from showing up in the sitemap and on Google (et all), otherwise they may be indexed by search engines
  disableSeoHiddenPages = false
  # Disables hidden pages from showing up on the tags page although the tag term will be displayed even if all pages are hidden
  disableTagHiddenPages = false
  # Javascript and CSS cache are automatically busted when new version of site is generated.
  # Set this to true to disable this behavior (some proxies don't handle well this optimization)
  disableAssetsBusting = false
  # Set this to true to disable copy-to-clipboard button for inline code.
  disableInlineCopyToClipBoard = false
  # A title for shortcuts in menu is set by default. Set this to true to disable it.
  disableShortcutsTitle = false
  # If set to false, a Home button will appear below the search bar on the menu.
  # It is redirecting to the landing page of the current language if specified. (Default is "/")
  disableLandingPageButton = true
  # When using mulitlingual website, disable the switch language button.
  disableLanguageSwitchingButton = false
  # Hide breadcrumbs in the header and only show the current page title
  disableBreadcrumb = true
  # If set to true, hide table of contents menu in the header of all pages
  disableToc = false
  # If set to false, load the Mermaid module on every page regardless if a Mermaid shortcode or Mermaid codefence is present
  disableMermaid = false
  # Specifies the remote location of the Mermaid js
  customMermaidURL = "https://unpkg.com/mermaid/dist/mermaid.min.js"
  # Initialization parameter for Mermaid, see Mermaid documentation
  mermaidInitialize = "{ \"theme\": \"default\" }"
  # If set to false, load the Swagger module on every page regardless if a Swagger shortcode is present
  disableSwagger = false
  # Specifies the remote location of the RapiDoc js
  customSwaggerURL = ""https://unpkg.com/rapidoc/dist/rapidoc-min.js"
  # Initialization parameter for Swagger, see RapiDoc documentation
  swaggerInitialize = "{ \"theme\": \"light\" }"
  # Hide Next and Previous page buttons normally displayed full height beside content
  disableNextPrev = true
  # Order sections in menu by "weight" or "title". Default to "weight";
  # this can be overridden in the pages frontmatter
  ordersectionsby = "weight"
  # Change default color scheme with a variant one. Eg. can be "red", "blue", "green" or an array like [ "blue", "green" ].
  themeVariant = "relearn-light"
  # Change the title separator. Default to "::".
  titleSeparator = "-"
  # If set to true, the menu in the sidebar will be displayed in a collapsible tree view.
  collapsibleMenu = false
  # If a single page can contain content in multiple languages, add those here
  additionalContentLanguage = [ "en" ]

A word on running your site in a subfolder

The theme runs best if your site is installed in the root of your webserver. If your site is served from a subfolder, eg. https://example.com/mysite/, you have to set the following lines to your config.toml

baseURL = "https://example.com/mysite/"
canonifyURLs = true

Without canonifyURLs=true URLs in sublemental pages (like sitemap.xml, rss.xml) will be generated falsly while your HTML files will still work. See https://github.com/gohugoio/hugo/issues/5226.

Activate search

If not already present, add the follow lines in the same config.toml file.

[outputs]
  home = ["HTML", "RSS", "JSON"]

Relearn theme uses the last improvement available in hugo version 20+ to generate a json index file ready to be consumed by lunr.js javascript search engine.

Hugo generate lunrjs index.json at the root of public folder. When you build the site with hugo server, hugo generates it internally and of course it doesn’t show up in the filesystem

Activate print support

You can activate print support to add the capability to print whole chapters or even the complete site. Just add the PRINT output format to your home, section and page in your config.toml as seen below:

[outputs]
  home = ["HTML", "RSS", "PRINT", "JSON"]
  section = ["HTML", "RSS", "PRINT"]
  page = ["HTML", "RSS", "PRINT"]

This will add a little printer icon in the top bar. It will switch the page to print preview when clicked. You can then send this page to the printer by using your browser’s usual print functionality.

Mermaid

The Mermaid configuration parameters can also be set on a specific page. In this case, the global parameter would be overwritten by the local one. See Mermaid for additional documentation.

Example:

Mermaid is globally disabled. By default it won’t be loaded by any page. On page “Architecture” you need a class diagram. You can set the Mermaid parameters locally to only load mermaid on this page (not on the others).

You also can disable Mermaid for specific pages while globally enabled.

Home Button Configuration

If the disableLandingPageButton option is set to false, a Home button will appear on the left menu. It is an alternative for clicking on the logo. To edit the appearance, you will have to configure two parameters for the defined languages:

[Languages]
[Languages.en]
...
landingPageName = "<i class='fas fa-home'></i> Home"
...
[Languages.pir]
...
landingPageName = "<i class='fas fa-home'></i> Arrr! Homme"
...

If those params are not configured for a specific language, they will get their default values:

landingPageName = "<i class='fas fa-home'></i> Home"

The home button is going to look like this:

Customization

The Relearn theme has been built to be as configurable as possible by defining multiple partials

In themes/hugo-theme-relearn/layouts/partials/, you will find all the partials defined for this theme. If you need to overwrite something, don’t change the code directly. Instead follow this page. You’d create a new partial in the layouts/partials folder of your local project. This partial will have the priority.

This theme defines the following partials :

• header.html: the header of the page. Not meant to be overwritten
• footer.html: the footer of the page.Not meant to be overwritten
• menu.html: left menu. Not meant to be overwritten
• search.html: search box. Not meant to be overwritten
• custom-header.html: custom headers in page. Meant to be overwritten when adding CSS imports. Don’t forget to include style HTML tag directive in your file.
• custom-footer.html: custom footer in page. Meant to be overwritten when adding Javacript. Don’t forget to include javascript HTML tag directive in your file.
• favicon.html: the favicon
• logo.html: the logo, on top left hand corner
• meta.html: HTML meta tags, if you want to change default behavior
• menu-pre.html: side-wide configuration to prepend to menu items. If you override this, it is your responsiblity to take the page’s pre setting into account.
• menu-post.html: side-wide configuration to append to menu items. If you override this, it is your responsiblity to take the page’s post setting into account.
• menu-footer.html: footer of the the left menu
• toc.html: table of contents
• content.html: the content page itself. This can be overridden if you wan’t to display page’s meta data above or below the content.
• content-footer: footer below the content, has a default implementation but you can overwrite it if you don’t like it.

Change the logo

Create a new file in layouts/partials/ named logo.html. Then write any HTML you want. You could use an img HTML tag and reference an image created under the static folder, or you could paste a SVG definition!

Change the favicon

If your favicon is a SVG, PNG or ICO, just drop off your image in your local static/images/ folder and name it favicon.svg, favicon.png or favicon.ico respectivly.

If no favicon file is found, the theme will lookup the alternative filename logo in the same location and will repeat the search for the list of supported file types.

If you need to change this default behavior, create a new file in layouts/partials/ named favicon.html. Then write something like this:

<link rel="icon" href="/images/favicon.bmp" type="image/bmp" />

Change the colors

The Relearn theme lets you choose between some predefined color variants in light or dark mode, but feel free to add one yourself!

You can preview the shipped variants by changing them in the variant selector at the bottom of the menu.

Single variant

Set the themeVariant value with the name of your theme file. That’s it!

[params]
  themeVariant = "relearn-light"

In the above exaple your theme file has to be named theme-relearn-light.css

Multiple variants

You can also set multiple variants. In this case, the first variant is the default choosen on first view and a variant switch will be shown in the menu footer.

[params]
  # Change default color scheme with a variant one.
  themeVariant = [ "relearn-light", "relearn-dark" ]

Roll your own

If you are not happy with the shipped variants you can either copy one of the shipped files, edit them in a text editor and configure the themeVariant parameter in your config.toml or just use the interactive variant generator.

Stylesheet generator

This interactive tool may help you to generate your own color variant stylesheet.

To get started, first select a color variant from the variant switch that fits you best as a starting point.

The graph is interactive and reflect the current colors. You can click on any of the colored boxes to adjust the respective color. The graph and the page will update accordingly.

The arrowed lines reflects how colors are inherited thru different parts of the theme if the descendent isn’t overwritten. If you want to delete a color and let it inherit from its parent, just delete the value from the input field.

To better understand this select the neon variant and modify the differnet heading colors. There, colors for the heading h2, h3 and h4 are explicitly set. h5 is not set and inherits its value from h4. h6 is also not set and inherits its value from h5.

Once you’ve changed a color, the variant switch will show a “My custom variant” entry and your changes are stored in the browser. You can change pages and even close the browser without losing your changes.

Once you are satisfied, you can download the new variants file and install it in your site.

History

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

Types

The Relearn theme defines two types of pages. Default and Chapter. Both can be used at any level of the documentation, the only difference being layout display.

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 under it.

You can define any HTML as prefix for the menu. In the example below, it’s just a number but that could be an icon.

+++
chapter = true
pre = "<b>1. </b>"
title = "Basics"
weight = 5
+++

### Chapter 1

# Basics

Discover what this Hugo theme is all about and the core-concepts behind it.

To tell the Relearn theme to consider a page as a chapter, set chapter=true in the Front Matter of the page.

Default

A Default page is any other content page.

+++
title = "Installation"
weight = 15
+++

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 this great documentation for beginners.

Create your project

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.

Front Matter configuration

Each Hugo page has to define a Front Matter in toml, yaml or json. This site will use toml in all cases.

The Relearn theme uses the following parameters on top of Hugo ones :

+++
# Table of contents (toc) is enabled by default. Set this parameter to true to disable it.
# Note: Toc is always disabled for chapter pages
disableToc = false
# If set, this will be used for the page's menu entry (instead of the `title` attribute)
menuTitle = ""
# If set, this will explicitly override common rules for the expand state of a page's menu entry
alwaysopen = true
# If set, this will explicitly override common rules for the sorting order of a page's submenu entries
ordersectionsby = "title"
# The title of the page in menu will be prefixed by this HTML content
pre = ""
# The title of the page in menu will be postfixed by this HTML content
post = ""
# Set the page as a chapter, changing the way it's displayed
chapter = false
# Hide a menu entry by setting this to true
hidden = false
# Display name of this page modifier. If set, it will be displayed in the footer.
LastModifierDisplayName = ""
# Email of this page modifier. If set with LastModifierDisplayName, it will be displayed in the footer
LastModifierEmail = ""
+++

Add icon to a menu entry

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

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

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
+++

Using a custom title for menu entries

By default, the Relearn theme will use a page’s title attribute for the menu item (or linkTitle if defined).

But a page’s title has to be descriptive on its own while the menu is a hierarchy. We’ve added the menuTitle parameter for that purpose:

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

+++
title = "Install on Linux"
menuTitle = "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 recursivley
• all remaining entries are not shown

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

Your Page

To configure your page, you basically have three choices:

1. Create an _index.md document in content folder and fill the file with Markdown content
2. Create an index.html file in the static folder and fill the file with HTML content
3. Configure your server to automatically redirect home page to one your documentation page

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.

It is pre-configured skeleton pages with default front matter. Please refer to the documentation for types of page to understand the differences.

Chapter

To create a Chapter page, run the following commands

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

It will create a page with predefined Front-Matter:

+++
chapter = true
pre = "<b>X. </b>"
title = "{{ replace .Name "-" " " | title }}"
weight = 5
+++

### Chapter X

# Some Chapter title

Lorem Ipsum.

Default

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

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

or

hugo new <chapter>/<name>.md

It will create a page with predefined Front-Matter:

+++
title = "{{ replace .Name "-" " " | title }}"
weight = 5
+++

Lorem Ipsum.

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 XHTML 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:

Headings

Headings from h1 through h6 are constructed with a # for each level:

# h1 Heading
## h2 Heading
### h3 Heading
#### h4 Heading
##### h5 Heading
###### h6 Heading

Renders to:

h1 Heading

h2 Heading

h3 Heading

h4 Heading

h5 Heading

h6 Heading

HTML:

<h1>h1 Heading</h1>
<h2>h2 Heading</h2>
<h3>h3 Heading</h3>
<h4>h4 Heading</h4>
<h5>h5 Heading</h5>
<h6>h6 Heading</h6>

Comments

Comments should be HTML compatible

<!--
This is a comment
-->

Comment below should NOT be seen:

Horizontal Rules

The HTML <hr> element is for creating a “thematic break” between paragraph-level elements. In Markdown, you can create a <hr> with --- - three consecutive dashes

renders to:

Paragraphs

Any text not starting with a special sign is written as normal, plain text and will be wrapped within <p></p> tags in the rendered HTML.

So this body copy:

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.

renders to this HTML:

<p>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.</p>

Text Markers

Bold

For emphasizing a snippet of text with a heavier font-weight.

The following snippet of text is rendered as bold text.

**rendered as bold text**

renders to:

rendered as bold text

and this HTML

<strong>rendered as bold text</strong>

Italics

For emphasizing a snippet of text with italics.

The following snippet of text is rendered as italicized text.

_rendered as italicized text_

renders to:

rendered as italicized text

and this HTML:

<em>rendered as italicized text</em>

Strikethrough

In GFM (GitHub flavored Markdown) you can do strikethroughs.

~~Strike through this text.~~

Which renders to:

Strike through this text.

HTML:

<del>Strike through this text.</del>

Blockquotes

For quoting blocks of content from another source within your document.

Add > before any text you want to quote.

> **Fusion Drive** combines a hard drive with a flash storage (solid-state drive) and presents it as a single logical volume with the space of both drives combined.

Renders to:

Fusion Drive combines a hard drive with a flash storage (solid-state drive) and presents it as a single logical volume with the space of both drives combined.

and this HTML:

<blockquote>
  <p><strong>Fusion Drive</strong> combines a hard drive with a flash storage (solid-state drive) and presents it as a single logical volume with the space of both drives combined.</p>
</blockquote>

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.

Renders to:

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.

Code

Inline code

Wrap inline snippets of code with `.

In this example, `<div></div>` should be wrapped as **code**.

Renders to:

In this example, <div></div> should be wrapped as code.

HTML:

Indented code

Or indent several lines of code by at least two spaces, as in:

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

Renders to:

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

HTML:

<pre>
  <code>
    // Some comments
    line 1 of code
    line 2 of code
    line 3 of code
  </code>
</pre>

Block code “fences”

Use “fences” ``` to block in multiple lines of code.

```
Sample text here...
```

HTML:

<pre>
  <code>Sample text here...</code>
</pre>

Syntax highlighting

GFM, or “GitHub Flavored Markdown” also supports syntax highlighting. To activate it, usually you simply add the file extension of the language you want to use directly after the first code “fence”, ```js, and syntax highlighting will automatically be applied in the rendered HTML.

See Code Highlighting for additional documentation.

For example, to apply syntax highlighting to JavaScript code:

```js
grunt.initConfig({
  assemble: {
    options: {
      assets: 'docs/assets',
      data: 'src/data/*.{json,yml}',
      helpers: 'src/custom-helpers.js',
      partials: ['src/partials/**/*.{hbs,md}']
    },
    pages: {
      options: {
        layout: 'default.hbs'
      },
      files: {
        './': ['src/templates/pages/index.hbs']
      }
    }
  }
};
```

Renders to:

grunt.initConfig({
  assemble: {
    options: {
      assets: 'docs/assets',
      data: 'src/data/*.{json,yml}',
      helpers: 'src/custom-helpers.js',
      partials: ['src/partials/**/*.{hbs,md}']
    },
    pages: {
      options: {
        layout: 'default.hbs'
      },
      files: {
        './': ['src/templates/pages/index.hbs']
      }
    }
  }
};

Tables

Tables are created 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. |

Renders to:

And this HTML:

<table>
  <tr>
    <th>Option</th>
    <th>Description</th>
  </tr>
  <tr>
    <td>data</td>
    <td>path to data files to supply the data that will be passed into templates.</td>
  </tr>
  <tr>
    <td>engine</td>
    <td>engine to be used for processing templates. Handlebars is the default.</td>
  </tr>
  <tr>
    <td>ext</td>
    <td>extension to be used for dest files.</td>
  </tr>
</table>

Right aligned text

Adding a colon on the right side of the dashes below any heading will right align text for that column.

| 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. |

Two tables adjacent

Links

Basic link

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

Renders to (hover over the link, there is no tooltip):

Assemble

HTML:

<a href="http://assemble.io">Assemble</a>

Add a tooltip

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

Renders to (hover over the link, there should be a tooltip):

Upstage

HTML:

<a href="https://github.com/upstage/" title="Visit Upstage!">Upstage</a>

Named Anchors

Named anchors enable you to jump to the specified anchor point on the same page. For example, each of these chapters:

# Table of Contents
  * [Chapter 1](#chapter-1)
  * [Chapter 2](#chapter-2)
  * [Chapter 3](#chapter-3)

will jump to these sections:

## Chapter 1 <a id="chapter-1"></a>
Content for chapter one.

## Chapter 2 <a id="chapter-2"></a>
Content for chapter one.

## Chapter 3 <a id="chapter-3"></a>
Content for chapter one.

NOTE that specific placement of the anchor tag seems to be arbitrary. They are placed inline here since it seems to be unobtrusive, and it works.

Images

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

![Minion](https://octodex.github.com/images/minion.png)

or

![Alt text](https://octodex.github.com/images/stormtroopocat.jpg "The Stormtroopocat")

Like links, Images also have a footnote style syntax

Alternative usage : note images

![Alt text][id]

With a reference later in the document defining the URL location:

[id]: https://octodex.github.com/images/dojocat.jpg  "The Dojocat"

Further image formatting

The Hugo Markdown parser supports additional non-standard functionality.

Resizing image

Add HTTP parameters 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=20pc)

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

![Minion](https://octodex.github.com/images/minion.png?height=50px&width=300px)

Add CSS classes

Add a HTTP classes parameter to the link image to add CSS classes. shadowand border are available but you could define other ones.

![stormtroopocat](https://octodex.github.com/images/stormtroopocat.jpg?classes=shadow)

![stormtroopocat](https://octodex.github.com/images/stormtroopocat.jpg?classes=border)

![stormtroopocat](https://octodex.github.com/images/stormtroopocat.jpg?classes=border,shadow)

Lightbox

Add a HTTP featherlight parameter to the link image to disable lightbox. By default lightbox is enabled using the featherlight.js plugin. You can disable this by defining featherlight to false.

![Minion](https://octodex.github.com/images/minion.png?featherlight=false)

Code highlighting

The Relearn theme uses Hugo’s built-in syntax highlighting for code.

Markdown syntax

Wrap the code block with three backticks and the name of the language. Highlight will try to auto detect the language if one is not provided.

```json
[
  {
    "title": "apples",
    "count": [12000, 20000],
    "description": {"text": "...", "sensitive": false}
  },
  {
    "title": "oranges",
    "count": [17500, null],
    "description": {"text": "...", "sensitive": false}
  }
]
```

Renders to:

[
  {
    "title": "apples",
    "count": [12000, 20000],
    "description": {"text": "...", "sensitive": false}
  },
  {
    "title": "oranges",
    "count": [17500, null],
    "description": {"text": "...", "sensitive": false}
  }
]

Supported languages

Hugo comes with a remarkable list of supported languages.

Recommended configuration

You can choose a color theme from the list of supported themes and add it in your config.toml

[markup]
  [markup.highlight]
    # if set to `guessSyntax = true`, there will be no unstyled code even if no language
    # was given BUT mermaid code fences will not work anymore! So this is a mandatory
    # setting for your site
    guessSyntax = false

    # choose a color theme or create your own
    style = "base16-snazzy"

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 config.toml and add a [[menu.shortcuts]] entry for each link your want to add.

Example from the current website:

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

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

[[menu.shortcuts]]
name = "<i class='fas fa-fw fa-bookmark'></i> Hugo Documentation"
identifier = "hugodoc"
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

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 overriden 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>"

Read more about hugo menu and hugo i18n translation strings

Configuration for Multilingual mode

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

Example from the current website:

[Languages]
  [Languages.en]
    title = "Hugo Relearn Theme"
    weight = 1
    languageName = "English"
    landingPageURL = "/"
    landingPageName = "<i class='fas fa-home'></i> Home"

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

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

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

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

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

  [Languages.pir]
    title = "Cap'n Hugo Relearrrn Theme"
    weight = 1
    languageName = "Arrr! Pirrrates"
    landingPageURL = "/pir/"
    landingPageName = "<i class='fas fa-home'></i> Arrr! Home"

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

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

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

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

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

Icons and logos

The Relearn theme for Hugo loads the Font Awesome library, allowing you to easily display any icon or logo available in the Font Awesome free collection.

Finding an icon

Browse through the available icons in the Font Awesome Gallery. Notice that the free filter is enabled, as only the free icons are available by default.

Once on the Font Awesome page for a specific icon, for example the page for the heart, copy the HTML reference and paste into the Markdown content.

The HTML to include the heart icon is:

<i class="fas fa-heart"></i>

Including in markdown

Paste the <i> HTML into markup and Font Awesome will load the relevant icon.

Built with <i class="fas fa-heart"></i> by Relearn and Hugo

Which appears as

Built with by Relearn and Hugo

Customising icons

Font Awesome provides many ways to modify the icon

• Change color (by default the icon will inherit the parent color)
• Increase or decrease size
• Rotate
• Combine with other icons

Check the full documentation on web fonts with CSS for more.

Multilingual and i18n

The Relearn theme is fully compatible with Hugo multilingual mode.

It provides:

• Translation strings for default values (English, Piratized English, Arabic, Simplified Chinese, Traditional Chinesse, Dutch, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Turkish, Vietnamese). Feel free to contribute!
• 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.

# 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

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 config.toml to broaden search.

[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 config.toml

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

Tags

The Relearn theme supports one default taxonomy of Hugo: the tag feature.

Configuration

Just add tags to any page:

+++
tags = ["tutorial", "theme"]
title = "Theme tutorial"
weight = 15
+++

Behavior

The tags are displayed at the top of the page, in their insertion order.

Each tag is a link to a Taxonomy page displaying all the articles with the given tag.

List all the tags

In the config.toml file you can add a shortcut to display all the tags

[[menu.shortcuts]]
name = "<i class='fas fa-tags'></i> Tags"
url = "/tags"
weight = 30

Attachments

The attachments shortcode displays a list of files attached to a page with adjustable color, title and icon.

Usage

While the examples are using shortcodes with named parameter you are free to also call this shortcode from your own partials.

{{% attachments sort="asc" /%}}

{{ partial "shortcodes/attachments.html" (dict
  "context" .
  "sort" "asc"
)}}

The shortcurt lists files found in a specific folder.

Currently, it supports two implementations for pages

1. If your page is a Markdown file, attachements must be placed in a folder named like your page and ending with .files.

   • content
     • _index.md
     • page.files
       • attachment.pdf
     • page.md

2. If your page is a folder, attachements must be placed in a nested files folder.

   • content
     • _index.md
     • page
       • index.md
       • files
         • attachment.pdf

Be aware that if you use a multilingual website, you will need to have as many folders as languages.

Parameter

Examples

Custom Title, List of Attachments Ending in pdf or mp4

{{% attachments title="Related files" pattern=".*(pdf|mp4)" /%}}

Info Styled Box, Descending Sort Order

{{% attachments style="info" sort="desc" /%}}

Style and Icons

For further examples for style, title and icon, see the notice shortcode documentation. The parameter are working the same way for both shortcodes, besides having different defaults.

Button

The button shortcode displays a clickable button with adjustable color, title and icon.

Mermaid

With the Mermaid library and shortcode, you can generate diagrams and flowcharts from text, in a similar manner as Markdown.

Usage

While the examples are using shortcodes with named parameter it is recommended to use codefences instead. This is because more and more other software supports Mermaid codefences (eg. GitHub) and so your markdown becomes more portable.

You are free to also call this shortcode from your own partials.

```mermaid
graph LR;
    If --> Then
    Then --> Else
```

{{< mermaid >}}
graph LR;
    If --> Then
    Then --> Else
{{< /mermaid >}}

{{ partial "shortcodes/mermaid.html" (dict
  "context" .
  "content" "graph LR;\nIf --> Then\nThen --> Else"
)}}

The generated graphs can be be panned by dragging them and zoomed by using the mousewheel. On mobile devices you can use finger gestures.

Parameter

Parameter are only supported when using shortcode syntax. Defaults are used when using codefence syntax.

Configuration

Mermaid is configured with default settings. You can customize Mermaid’s default settings for all of your files thru a JSON object in your config.toml, override these settings per page thru your pages frontmatter or override these setting per diagramm thru diagram directives.

The JSON object of your config.toml / frontmatter is forwarded into Mermaid’s mermaid.initialize() function.

See Mermaid documentation for all allowed settings.

The theme setting can also be set by your used color variant. This will be the sitewide default and can - again - be overridden by your settings in config.toml, frontmatter or diagram directives.

Global Configuration File

[params]
  mermaidInitialize = "{ \"theme\": \"dark\" }"

[markup]
  [markup.highlight]
    # if set to `guessSyntax = true`, there will be no unstyled code even if no language
    # was given BUT mermaid code fences will not work anymore! So this is a mandatory
    # setting for your site
    guessSyntax = false
