= jekyll-tagging

By Arne Eilermann arne@kleinerdrei.net and Jens Wille jens.wille@uni-koeln.de

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

== Usage

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 site 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.)

=== Pretty page links

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

=== Ignoring tags

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
=== Example tag page layout

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

layout: default

{{ page.tag }}

{% for post in page.posts %}

• {{ post.title }} ({{ post.date | date_to_string }} | Tags: {{ post | tags }})

{% endfor %}

=== Example layout of an Atom feed

layout: nil

<?xml version="1.0" encoding="utf-8"?>




{{ site.time | date_to_xmlschema }}
http://example.com/tag/{{ page.tag }}.html

Author Here

{% for post in page.posts %}



{{ post.date | date_to_xmlschema }}
http://example.com{{ post.id }}
{{ post.content | xml_escape }}

{% endfor %}
