|
## 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 `hugo.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
|
||
|
|
|
||
|
|
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, as well as other parameters to hide or alter urls in the menu. You can choose which folder to use for generating menu with `BookSection` configuration parameter.
|
||
|
|
|
||
|
|
## 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 `hugo.toml` file.
|
||
|
|
You can also see the `yaml` example [here](https://github.com/alex-shpak/hugo-book/blob/master/exampleSite/hugo.yaml).
|
||
|
|
|
||
|
|
```toml

||
|

|
|

|
||
|
|
|
||
|
|
# (Optional, default docs) Specify section of content to render as menu
|
||
|
|

|
|
||
|
|
# Set source repository location.
|
||
|
|
# Used for 'Last Modified' and 'Edit this page' links.
|
||
|
|
BookRepo = 'https://github.com/alex-shpak/hugo-book'
|
||
|
|
|
||
|
|
# Specifies commit portion of the link to the page's last modified commit hash for 'doc' page
|
||
|
|
# type.
|
||
|
|
# 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.
|
||
|
|
# Disabled by default. Uncomment to enable. Requires 'BookRepo' param.
|
||
|
|
# Path must point to the site directory.

|
||
|
|
|
||
|
|
# (Optional, default January 2, 2006) Configure the date format used on the pages
|
||
|

||
|
|

|
||
|
|
|

|

||
|
|
BookSearch = 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.
|
||
|
|

|
# 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

|
||
|
|
BookServiceWorker = true
|
||
|
|
```
|
||
|
|
|
||
|
|
### 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.
|
||
|
|
weight = 10
|
||
|
|
|
||
|
|
# (Optional) Set to 'true' to mark page as flat section in file-tree menu.
|
||
|
|
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.
|
||
|
|
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.
|
||
|
|
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.
