## 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 .
```
```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).
```toml
# (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 light) Sets color theme: light, dark or auto.
# Theme 'auto' switches between dark and light modes based on browser/os preferences
BookTheme = 'light'

# Start and end levels can be controlled with markup.tableOfContents setting.
# You can also specify this parameter per page in front matter.

# /static/logo.png then the path would be 'logo.png'
BookLogo = 'logo.png'

# When not specified file structure and weights will be used
# Deprecated, to be removed in June 2022
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'
# 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/
# 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.
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'

# 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 partials/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](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 `` tag |
| `layouts/partials/docs/inject/body.html` | Before closing `` tag |
