Textbook From Scratch

This gives the basic steps for creating a brand new Hugo textbook from scratch.

Basic Site Setup

The first steps come from the Hugo Quick Start Guide

1. Install Hugo from the Hugo Releases. You should have version 0.101.0 or higher.
2. Create a new site: hugo new site <sitename>.
3. Open the site’s directory: cd <sitename>.
4. Start a git repository: git init.
5. Add the theme: git submodule add https://github.com/ksu-cs-textbooks/hugo-theme-relearn themes/hugo-theme-relearn
6. Update the config.toml file:
   1. Best way to start is simply to copy the config.toml file for the starter site. It is well documented.
   2. Update the baseURL at the top to match the URL where the site will eventually be deployed.
   3. Update the title to match the site’s name
   4. Update the theme to be just theme = ["hugo-theme-relearn"] (remove the "plausible-hugo" part)
   5. Under [params], update the following:
      1. editURL to match the location where files can be edited in GitLab or GitHub.
      2. author used for metadata
      3. description used for metadata
      4. commitURL to match the location where individual commits can be found.
      5. Most of the parameters are documented in the Hugo Theme Relearn Documentation
   6. Remove the [params.plausible] section - it is not used by the textbooks site.
7. Preview the site using hugo serve. It will be available at the URL given in the output. If the site loads with default content, then it is working.

Additional Configuration

Perform a few additional steps to make things work smoothly.

1. Create a .gitignore file in the site’s base directory with the following content:

/public/
/resources/_gen
.hugo_build.lock

2. If you are using Visual Studio Code to edit the site, create a .vscode folder in the site’s base directory, and then a settings.json file inside of that directory with the following content to change the sort order of your editor’s file explorer:

{
    "explorer.sortOrder": "mixed"
}

GitLab Repository Setup

Once the site is working locally, set up a repository on the CS GitLab server to store the data.

1. We recommend storing the textbook in the CS Textbooks group. Contact another textbook author to get access.
2. Create a repository that matches your textbook name. Use the other repositories as a naming guide. Do not initialize the repository in GitLab by creating a README file.
   1. You can choose to make your repository private (accessible only to the group), internal (accessible to anyone with a CS account), or public (accessible to anyone). Only those with permissions can update the repository (typically group members), but others may be able to view the content.
3. In the site directory on your local system, add the repository’s URL as a remote: git remote add origin <url>
4. Commit and push: git commit -m "Initial Commit" && git push -u origin main (substitute master for main if needed) 5. Make sure that you don’t commit the .hugo_build.lock file - it should be excluded via the .gitignore file created above.

Initial Content Creation

Now that the site is working, it is time to create some basic content.

Homepage

To create a home page, create a new _index.md file in the content directory. It should have at least the following content:

+++
archetype = "home"
title = "Homepage"
+++

Lorem Ipsum

You can also create this page using the command hugo new --kind home _index.md from the site’s directory and then modifying the content a bit.

See the Hugo Theme Relearn Documentation or Hugo Documentation for more on how to use the front matter of each page.

Chapter

To create a chapter, first create a folder with the chapter’s name in the content directory. We recommend including a number in front of the name to help with sorting, such as 01-introduction. Then, inside of that folder, create a new _index.md file with the following content:

+++
archetype = "chapter"
ordinal = "1"
title = "Introduction"
pre = "<b>1. </b>"
weight = 1
+++

Lorem Ipsum.

You can also create this page using the command hugo new --kind chapter 01-introduction/_index.md from the site’s directory and then modifying the content a bit.

Content Page

To create a content page, simply create a file inside of the desired directory with the .md file extension. Like chapters, we recommend adding a number in front of the file name to help with sorting, such as 01-welcome.md. Place the following content in the page:

---
title: "Welcome"
pre: "1. "
weight: 1
---

Lorem Ipsum.

You can also create this page using the command hugo new 01-introduction/01-welcome.md from the site’s directory and then modifying the content a bit.

Logo

The site right now uses a default logo based on the site’s title in config.toml. To override that, create a file at layouts/partials/logo.html in the site with the following content:

<a id="logo" href="{{ .Site.Home.RelPermalink | default ("/" | relLangURL) }}">
  Hugo Starter
</a>

Replace the text with the desired logo content. Alternatively, an image can be used. Place the image in the static/images/ folder and adapt the following HTML:

<a id="logo" href="{{ .Site.Home.RelPermalink | default ("/" | relLangURL) }}">
    <img src="/images/logo.png" alt="Logo" style="width: 100%">
</a>

Sidebar Footer

The sidebar footer can also be overridden by creating a file at layouts/partials/menu-footer.html. It is best to simply copy the existing content in themes/hugo-theme-relearn/layouts/partials/menu-footer.html and edit it from that template.

Additional Content

From there, you can continue to create additional chapters and pages as needed. For more advanced content structures, look through the source code to this site. It includes examples for page bundles, leaf bundles, hidden pages, non-printable pages, syllabus pages, video content, historical content, and more.
