jekyll-tagging is a Jekyll plugin, to add a tag cloud and per tag pages plus feeds to your Jekyll generated Website.
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.)
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
(Save this to _layouts/tag_page.html if using the _config.yml snippet above.)
