## Installation
|
||
|
|
|
||
|
|
### Install as git submodule
|
||
|
|
Navigate to your hugo project root and run:
|
||
|
|
|
||
|
|
```
|
||
|
|
git submodule add https://github.com/alex-shpak/hugo-book themes/hugo-book
|
||
|
|
```
|
||
|
|
|
||
|
|
Then run hugo (or set `theme = "hugo-book"`/`theme: hugo-book` in configuration file)
|
||
|
|
|
||
|
|
```
|
||
|
|
hugo server --minify --theme hugo-book
|
||
|
|
```
|
||
|
|
|
||
|
|
### Install as hugo module
|
||
|
|
|
||
|
|
You can also add this theme as a Hugo module instead of a git submodule.
|
||
|
|
|
||
|
|
Start with initializing hugo modules, if not done yet:
|
||
|
|
```
|
||
|
|
hugo mod init github.com/repo/path
|
||
|
|
```
|
||
|
|
|
||
|
|
Navigate to your hugo project root and add [module] section to your `config.toml`:
|
||
|
|
|
||
|
|
```toml
|
||
|
|
[module]
|
||
|
|
[[module.imports]]
|
||
|
|
path = 'github.com/alex-shpak/hugo-book'
|
||
|
|
```
|
||
|
|
|
||
|
|
Then, to load/update the theme module and run hugo:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
hugo mod get -u
|
||
|
|
hugo server --minify
|
||
|
|
```
|
||
|
|
|
||
|
|
### Creating site from scratch
|
||
|
|
|
||
|
|
Below is an example on how to create a new site from scratch:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
hugo new site mydocs; cd mydocs
|
||
|
|
git init
|
||
|
|
git submodule add https://github.com/alex-shpak/hugo-book themes/hugo-book
|
||
|
|
cp -R themes/hugo-book/exampleSite/content.en/* ./content
|
||
|
|
```
|
||
|
|
|
||
|
|
```sh
|
||
|
|
hugo server --minify --theme hugo-book
|
||
|
|
```
|
||
|
|
|
||
|
|
## Menu
|
||
|
|
|
||
|
|
### File tree menu (default)
|
||
|
|
|
||
|
|
By default, the theme will render pages from the `content/docs` section as a menu in a tree structure.
|
||
|
|
You can set `title` and `weight` in the front matter of pages to adjust the order and titles in the menu.
|
||
|
|
|
||
|
|
### Leaf bundle menu (Deprecated, to be removed in June 2022)
|
||
|
|
|
||
|
|
You can also use leaf bundle and the content of its `index.md` file as menu.
|
||
|
|
Given you have the following file structure:
|
||
|
|
|
||
|
|
```
|
||
|
|
├── content
|
||
|
|
│ ├── docs
|
||
|
|
│ │ ├── page-one.md
|
||
|
|
│ │ └── page-two.md
|
||
|
|
│ └── posts
|
||
|
|
│ ├── post-one.md
|
||
|
|
│ └── post-two.md
|
||
|
|
```
|
||
|
|
|
||
|
|
Create a file `content/menu/index.md` with the content:
|
||
|
|
|
||
|
|
```md
|
||
|
|
+++
|
||
|
|
headless = true
|
||
|
|
+++
|
||
|
|
|
||
|
|
- [Book Example]({{< relref "/docs/" >}})
|
||
|
|
- [Page One]({{< relref "/docs/page-one" >}})
|
||
|
|
- [Page Two]({{< relref "/docs/page-two" >}})
|
||
|
|
- [Blog]({{< relref "/posts" >}})
|
||
|
|
```
|
||
|
|
|
||
|
|
And Enable it by setting `BookMenuBundle: /menu` in Site configuration.
|
||
|
|
|
||
|
|
- [Example menu](https://github.com/alex-shpak/hugo-book/blob/master/exampleSite/content.en/menu/index.md)
|
||
|
|
- [Example config file](https://github.com/alex-shpak/hugo-book/blob/master/exampleSite/config.yaml)
|
||
|
|
- [Leaf bundles](https://gohugo.io/content-management/page-bundles/)
|
||
|
|
|
||
|
|
## Blog
|
||
|
|
|
||
|
|
A simple blog is supported in the section `posts`.
|
||
|
|
A blog is not the primary usecase of this theme, so it has only minimal features.
|
||
|
|
|
||
|
|
## Configuration
|
||
|
|
|
||
|
|
### Site Configuration
|
||
|
|
|
||
|
|
There are a few configuration options that you can add to your `config.toml` file.
|
||
|
|
You can also see the `yaml` example [here](https://github.com/alex-shpak/hugo-book/blob/master/exampleSite/config.yaml).

|
||
|
|
|
||
|
|
# Specifies commit portion of the link to the page's last modified commit hash for 'doc' page
|
||
|

# Required if 'BookRepo' param is set.
|
||
|
|
# Value used to construct a URL consisting of BookRepo/BookCommitPath/<commit-hash>
|
||
|
|
# Github uses 'commit', Bitbucket uses 'commits'
|
||
|
|
BookCommitPath = 'commit'
|
||
|
|
|
||
|
|
# Enable 'Edit this page' links for 'doc' page type.
|
||
|
|

|
|
|
||
|
|

|
||
|
|
# - In git information
|
||
|
|
# - In blog posts

||
|
|
BookDateFormat = 'Jan 2, 2006'
|
||
|
|
|
||
|
|
# (Optional, default true) Enables search function with flexsearch,
|
||
|

|
||
|
|
BookSearch = true
|
||
|
|
|
||
|
|
# (Optional, default true) Enables comments template on pages
|
||
|
|

|
|
||
|
|
# /!\ 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

|
||
|
|

|
||
|
|
```
|
||
|
|
|
||
|
|
### Multi-Language Support
|
||
|
|
|
||
|
|
Theme supports Hugo's [multilingual mode](https://gohugo.io/content-management/multilingual/), just follow configuration guide there. You can also tweak search indexing configuration per language in `i18n` folder.
|
||
|
|
|
||
|
|
### Page Configuration
|
||
|
|
|
||
|
|
You can specify additional params in the front matter of individual pages:
|
||
|
|
|
||
|
|
```toml
|
||
|
|
# 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 'true' to mark page as flat section in file-tree menu (if BookMenuBundle not set)
|
||
|
|
bookFlatSection = false
|
||
|
|
|
||
|
|
# (Optional) 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 = false
|
||
|
|
|
||
|
|
# (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
|
||
|
|
|
||
|
|
# (Optional) Set to 'false' to exclude page from search index.
|
||
|
|
bookSearchExclude = true
|
||
|
|
|
||
|
|
# (Optional) Set explicit href attribute for this page in a menu (if BookMenuBundle not set)
|
||
|
|
bookHref = ''
|
||
|
|
```
|
||
|
|
|
||
|
|
### Partials
|
||
|
|
|
||
|
|
There are layout partials available for you to easily override components of the theme in `layouts/partials/`.
|
||
|
|
|
||
|
|
In addition to this, there are several empty partials you can override to easily add/inject code.
|
||
|
|
|
||
|
|
| Empty 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 |
|
||
|
|
| `layouts/partials/docs/inject/toc-before.html` | At the beginning of table of contents block |
|
||
|
|
| `layouts/partials/docs/inject/toc-after.html` | At the end of table of contents block |
|
||
|
|
|
||
|
|
### 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) |
|
||
|
|
| `assets/mermaid.json` | Replace Mermaid initialization config |
|
||
|
|
|
||
|
|
### Plugins
|
||
|
|
|
||
|
|
There are a few features implemented as pluggable `scss` styles. Usually these are features that don't make it to the core but can still be useful.
|
||
|
|
|
||
|
|
| Plugin | Description |
|
||
|
|
| --------------------------------- | ----------------------------------------------------------- |
|
||
|
|
| `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 plugins, add `@import "plugins/{name}";` to `assets/_custom.scss` in your website root.
|
||
|
|
|
||
|
|
### Hugo Internal Templates
|
||
|
|
|
||
|
|
There are a few hugo templates inserted in `<head>`
|
||
|
|
|
||
|
|
- [Google Analytics](https://gohugo.io/templates/internal/#google-analytics)
|
||
|
|
- [Open Graph](https://gohugo.io/templates/internal/#open-graph)
|
||
|
|
|
||
|
|
To disable Open Graph inclusion you can create your own empty file `\layouts\_internal\opengraph.html`.
|
||
|
|
In fact almost empty not quite empty because an empty file looks like absent for HUGO. For example:
|
||
|
|
```
|
||
|
|
<!-- -->
|
||
|
|
```
|
||
|
|
|
||
|
|
## Shortcodes
|
||
|
|
|
||
|
|
- [Buttons](https://hugo-book-demo.netlify.app/docs/shortcodes/buttons/)
|
||
|
|
- [Columns](https://hugo-book-demo.netlify.app/docs/shortcodes/columns/)
|
||
|
|
- [Details](https://hugo-book-demo.netlify.app/docs/shortcodes/details/)
|
||
|
|
- [Hints](https://hugo-book-demo.netlify.app/docs/shortcodes/hints/)
|
||
|
|
- [KaTeX](https://hugo-book-demo.netlify.app/docs/shortcodes/katex/)
|
||
|
|
- [Mermaid](https://hugo-book-demo.netlify.app/docs/shortcodes/mermaid/)
|
||
|
|
- [Tabs](https://hugo-book-demo.netlify.app/docs/shortcodes/tabs/)
|
||
|
|
|
||
|
|
By default, Goldmark trims unsafe outputs which might prevent some shortcodes from rendering. It is recommended to set `markup.goldmark.renderer.unsafe=true` if you encounter problems.
|
||
|
|
|
||
|
|
```toml
|
||
|
|
[markup.goldmark.renderer]
|
||
|
|
unsafe = true
|
||
|
|
```
|
||
|
|
|
||
|
|
If you are using `config.yaml` or `config.json`, consult the [configuration markup](https://gohugo.io/getting-started/configuration-markup/)
|
||
|
|
|
||
|
|
## Versioning
|
||
|
|
|
||
|
|
This theme follows a 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 the released versions. If you want to live on the bleeding edge of changes, you can use the `master` branch and update your website when needed.
