Category aware next attribute for a Jekyll post

category_aware_next_generator.rb

module Jekyll
  class CategoryAwareNextGenerator < Generator

    safe true
    priority :high

    def generate(site)
      site.categories.each_pair do |category_name, posts|
        posts.sort! { |a, b| b <=> a }

        posts.each do |post|
          position = posts.index post

          if position && position < posts.length - 1
            category_next = posts[position + 1]
          else
            category_next = nil
          end

          post.data["#{category_name}_next"] = category_next unless category_next.nil?
        end
      end
    end
  end
end

Hi! Is it possible to adapt this code to follow the order of the posts (configured in the front-matter)?

I use this in the loop:

{%- assign sorted_posts = site.categories['category'] | sort: 'order' -%}

And this in the front-matter: sort: 57

I guess it is, you have to ask someone who is familiar with Jekyll. I haven't worked with it for almost 8 years, so I'm of no help.

Oh, ok, thank you! Later I will try to implement it.
