Configuration

Site Configuration

There are few configuration options you can add to your config.toml file.
You can also see yaml example here.

# (Optional) Set Google Analytics if you use it to track your website.
# Always put it on the top of the configuration file, otherwise it won't work
googleAnalytics = "UA-XXXXXXXXX-X"

# (Optional) If you provide a Disqus shortname, comments will be enabled on
# all pages.
disqusShortname = "my-site"

# (Optional) Set this to true if you use capital letters in file names
disablePathToLower = true

# (Optional) Set this to true to enable 'Last Modified by' date and git author
#  information on 'doc' type pages.
enableGitInfo = true

# (Optional) Theme is intended for documentation use, therefore it doesn't render taxonomy.
# You can remove related files with config below
disableKinds = ['taxonomy', 'taxonomyTerm']
  
[params]
  # (Optional, default true) Controls table of contents visibility on right side of pages.
  # Start and end levels can be controlled with markup.tableOfContents setting.
  # You can also specify this parameter per page in front matter.
  BookToC = true
  
  # (Optional, default none) Set the path to a logo for the book. If the logo is
  # /static/logo.png then the path would be 'logo.png'
  BookLogo = 'logo.png'
  
  # (Optional, default none) Set leaf bundle to render as side menu
  # When not specified file structure and weights will be used
  BookMenuBundle = '/menu'
  
  # (Optional, default docs) Specify section of content to render as menu
  # You can also set value to "*" to render all sections to menu
  BookSection = 'docs'
  
  # Set source repository location.
  # Used for 'Last Modified' and 'Edit this page' links.
  BookRepo = 'https://github.com/alex-shpak/hugo-book'
  
  # Enable 'Edit this page' links for 'doc' page type.
  # Disabled by default. Uncomment to enable. Requires 'BookRepo' param.
  # Path must point to the site directory.
  BookEditPath = 'edit/master/exampleSite'
  
  # (Optional, default January 2, 2006) Configure the date format used on the pages
  # - In git information
  # - In blog posts
  BookDateFormat = 'Jan 2, 2006'
  
  # (Optional, default true) Enables search function with flexsearch,
  # Index is built on fly, therefore it might slowdown your website.
  # Configuration for indexing can be adjusted in i18n folder per language.
  BookSearch = true

  # (Optional, default true) Enables comments template on pages
  # By default partals/docs/comments.html includes Disqus template
  # See https://gohugo.io/content-management/comments/#configure-disqus
  # Can be overwritten by same param in page frontmatter
  BookComments = true

  # /!\ This is an experimental feature, might be removed or changed at any time
  # (Optional, experimental, default false) Enables portable links and link checks in markdown pages.
  # Portable links meant to work with text editors and let you write markdown without {{< relref >}} shortcode
  # Theme will print warning if page referenced in markdown does not exists.
  BookPortableLinks = true

  # /!\ This is an experimental feature, might be removed or changed at any time
  # (Optional, experimental, default false) Enables service worker that caches visited pages and resources for offline use.
  BookServiceWorker = true

Multi-Language Support

Theme supports Hugo's multilingual mode, just follow configuration guide there. You can also tweak search indexing configuration per language in i18n folder.

Page Configuration

You can specify additional params per page in front matter

# Set type to 'docs' if you want to render page outside of configured section or if you render section other than 'docs'
type = 'docs'

# Set page weight to re-arrange items in file-tree menu (if BookMenuBundle not set)
weight = 10

# (Optional) Set to mark page as flat section in file-tree menu (if BookMenuBundle not set)
bookFlatSection = true

# (Optional, Experimental) Set to hide nested sections or pages at that level. Works only with file-tree menu mode
bookCollapseSection = true

# (Optional) Set true to hide page or section from side menu (if BookMenuBundle not set)
bookHidden = true

# (Optional) Set 'false' to hide ToC from page
bookToC = true

# (Optional) If you have enabled BookComments for the site, you can disable it for specific pages.
bookComments = true

Partials

There are few empty partials you can override in layouts/partials/

Partial	Placement
`layouts/partials/docs/inject/head.html`	Before closing `<head>` tag
`layouts/partials/docs/inject/body.html`	Before closing `<body>` tag
`layouts/partials/docs/inject/footer.html`	After page footer content
`layouts/partials/docs/inject/menu-before.html`	At the beginning of `<nav>` menu block
`layouts/partials/docs/inject/menu-after.html`	At the end of `<nav>` menu block
`layouts/partials/docs/inject/content-before.html`	Before page content
`layouts/partials/docs/inject/content-after.html`	After page content

Extra Customisation

File	Description
`static/favicon.png`	Override default favicon
`assets/_custom.scss`	Customise or override scss styles
`assets/_variables.scss`	Override default SCSS variables
`assets/_fonts.scss`	Replace default font with custom fonts (e.g. local files or remote like google fonts)

Plugins

There are few features implemented as plugable scss styles. Usually this are features that doesn't make it to the core but still might be useful.

Plugin	Description
`assets/plugins/_dark.scss`	Switches site to dark mode
`assets/plugins/_numbered.scss`	Makes headings in markdown numbered, e.g. `1.1`, `1.2`
`assets/plugins/_scrollbars.scss`	Overrides scrollbar styles to look similar across platforms

To enable plugin add @import "plugins/{name}"; to assets/_custom.scss in your website root. Exception is _dark.scss which contains only variables and should be added to assets/_variables.scss.

Hugo Internal Templates

There are few hugo templates inserted in <head>

Shortcodes

By default, Goldmark trims unsafe output which might prevent some shortcodes from rendeting. It's recommended to set markup.goldmark.renderer.unsafe=true in case of problems.

[markup.goldmark.renderer]
  unsafe = true

If you are using config.yaml or config.json, consult configuration markup

Versioning

Theme follows simple incremental versioning. e.g. v1, v2 and so on. There might be breaking changes between versions.

If you want lower maintenance use one of released versions. If you want to live on the edge of changes you can use master branch and update your website when needed.
