Zybooks Liquid Tag Plugin

This allows a link to the most recent version of zybooks, without having to change links throughout the entire website. Instead the link updates based on the contents of the _config.yml direction.

Make sure the _config.yml includes the line zybook, and book-id

zybook:  
  book_id: "COLOSTATECS1634Summer2020"

Replace COLOSTATE... with your latest book ID, that is find in the URL of the book. For example:

https://learn.zybooks.com/zybook/COLOSTATECS1634Summer2020/`

{% zybook chapter:x section:x %}Link text{% endzybook %}

For example:

{% zybook chapter:13 section:2 %}Loops{%endzybook%}

would create the following link (assuming Summer Book)

<a href="https://learn.zybooks.com/zybook/COLOSTATECS1634Summer2020/chapter/13/section/2" target="_blank">Loops</a>

Arguments are optional, possible arguments are as follows:

• chapter
  defaults to nothing, directing the link to the zybook TOC if omitted
• section
  defaults to 1
• resource_id
  for the content_resource_id in links, defaults to nothing

The text between the tag block is used for the link text.

All arguments can also be included in the _config.yml. They will be used as default arguments, but local (placing in the tag) use overwrites the _config.yml setting. In most cases, the only option in _config.yml that makes sense is book-id.
