Titleize Gem Plugin Example

This site is a work-in-progress. Some of the information is incomplete and may not work as described. See the homepage for details.

Instead of writing your own title case plugin, why not use an existing gem? Grant Hollingworth has written a titleize gem which works well, so all we’d need to do is register a Liquid filter to use it in our Jekyll project.

First add the gem you wish to use in your Gemfile. Then build your plugin.

require 'titleize'

module Jekyll
  module Titleize
    def titleize(title)
      title.titleize
    end
  end
end

Liquid::Template.register_filter(Jekyll::Titleize)

Inside the above titleize() method, we’re calling .titleize from the titleize gem and returning it via the Liquid filter, like this:

{{ page.title | titleize }}
