h32-jekyll-tagging¶ ↑

A custom version of “jekyll-tagging” for my own (hatsat32) use.

Fixes some issues about slugifying tags.

gem install h32-jekyll-tagging

jekyll-tagging is a Jekyll plugin, to add a tag cloud and per tag pages plus feeds to your Jekyll generated Website.

This plugin does not reinvent Jekyll’s tagging feature. It just makes it easy to use. <jekyllrb.com/docs/frontmatter/>

Add space-delimited lowercase tags to FrontMatter, e.g.

---
author: Willow Rosenberg
tags: feminism anti-capitalism witchcraft
---

Install it:

gem install jekyll-tagging

Add this line to your Jekyll project’s Gemfile:

gem 'jekyll-tagging'

Add the following to your _plugins/ext.rb file:

require 'jekyll/tagging'

And in your _config.yml you have to define your layout used to generate tag pages like:

tag_page_layout: tag_page
tag_page_dir: tag

This will look for _layouts/tag_page.html, and use it to generate tag pages into the _site/tag directory.

Now you have a new filter called tag_cloud which you can use with the site object as argument in your layout to get a cloud of all your site’s tags. The tags are linked to their related tag page. Furthermore, you have a tags filter which you can feed with a post or a page object to get a link list of all its tags.

You can optionally define a per tag Atom/RSS feed. In your _config.yml define the following:

tag_feed_layout: tag_feed
tag_feed_dir: tag

(tag_page_dir and tag_feed_dir can have the same value.)

If your Jekyll permalink configuration is set to something other than :pretty, and you still want to have pretty tag links define the following in your _config.yml:

tag_permalink_style: pretty

Sometimes you don’t want tag pages generated for certain pages. That’s ok! Just add ignored_tags: [tags,to,ignore] to your _config.yml

You can attach extra data to generated tag pages by specifying tag_page_data in _config.yml (this also works for tag_feed_data). For example, you might want to exclude tag pages from being picked up by ‘jekyll-sitemap`:

tag_page_data:
  sitemap: false

(Save this to _layouts/tag_page.html if using the _config.yml snippet above.)

---
layout: default
---
<h2>{{ page.tag }}</h2>
<ul>
{% for post in page.posts %}
  <li><a href="{{ post.url }}">{{ post.title }}</a> ({{ post.date | date_to_string }} | Tags: {{ post | tags }})</li>
{% endfor %}
</ul>

<div id="tag-cloud">
  {{ site | tag_cloud }}
</div>

(Save this to _layouts/tag_feed.xml if using the _config.yml snippet above.)

---
layout: nil
---
<?xml version="1.0" encoding="utf-8"?>
<feed xmlns="http://www.w3.org/2005/Atom">
 <title>Your Title - {{ page.tag }}</title>
 <link href="http://example.com{{ page.url }}" rel="self"/>
 <link href="http://example.com/tag/{{ page.tag }}.html"/>
 <updated>{{ site.time | date_to_xmlschema }}</updated>
 <id>http://example.com/tag/{{ page.tag }}.html</id>
 <author>
   <name>Author Here</name>
 </author>
 {% for post in page.posts %}
 <entry>
   <title>{{ post.title }}</title>
   <link href="http://example.com{{ post.url }}"/>
   <updated>{{ post.date | date_to_xmlschema }}</updated>
   <id>http://example.com{{ post.id }}</id>
   <content type="html">{{ post.content | xml_escape }}</content>
 </entry>
 {% endfor %}
</feed>
