cloudtag broken in Jekyll >= 4.1.0

Discussed in #28

I'm playing around with vanilla version of chulapa (changed the skin etc. but nothing major), but the /tags page has issues for me. Seems there is never a tag.name assigned. If I add a print statement to the tag in cloudtag.html like this:

{% assign grouptag = alldocs | map: 'tags' | join: ',' | split: ',' | group_by: tag | sort: 'size' | reverse %} {%- for tag in grouptag -%} {{ tag }} {%- if forloop.first -%} {%- assign sizemax = tag.size -%} {%- elsif forloop.last -%} {% assign mid = tag.size | plus: sizemax | divided_by: 2 %} {%- endif -%} {%- endfor -%}

I get the following:

{"name"=>"", "items"=>["starter", "syntax", "kramdown", "starter", "syntax", "markdown", "skin", "bootstrap", "current-theme", "header-hero", "image", "demo", "landscape", "trips", "downtown", "project-links", "wikipedia", "image", "example", "demo", "layout", "guest-author", "image", "landscape", "trips", "downtown", "edinburgh", "kramdown", "bootstrap", "wikipedia", "demo", "image", "urban art", "street", "downtown", "image", "random", "manuscript", "markdown", "exciting-stuff", "wikipedia", "manuscript", "random", "diary", "school", "manuscript", "random", "exciting-stuff", "wikipedia", "pirates", "random", "wikipedia", "random", "exciting-stuff"], "size"=>54}

The rest of the page shows tags.size correctly, but nothing else obviously since tag.name is empty.

Seems something goes wrong in the grouptag assignment but I cannot figure it out. Any ideas?

This is happening in Jekyll >=4.1.0 due a change on behaviour (maybe we were leveraging on a bug for creating the cloud tag).

See jekyll/jekyll#8214

@cargocultprogramming I just see as a solution either to downgrade to Jekyll 4.0.1 or less or try the solution based on plugins on jekyll/jekyll#8214 (comment)

Alright - solved this for me along the lines of the jekyll discussion linked above.

I added a custom filter like this:

module Jekyll
    module TagFilters
        def count_by_item(input)
            input = input.is_a?(String) ? input.split(',') : input
            counts = Hash.new(0)
            input.flatten.each do |name|
                name = name.strip
                counts[name] += 1
            end
            sorted_counts = counts.sort_by { |tag, count| -count }
            sorted_counts.to_h
        end
    end
end
Liquid::Template.register_filter(Jekyll::TagFilters)

Then in jekyll you can

{% assign tag_count = alldocs | map: 'tags' | count_by_item %}

Then you can loop over tag_count as now over grouptag and replace tag.name with tag[0] and tag.size with tag[1] and it's all there.

EDIT. Kept hacking it and I figured it out. I think i'm squared now.

Mainly didn't understand the jekyll I needed to put in my page and what to do.

For anyone that finds this, I went to the main chulapa repo and looked at the cloudtag.html file and used that in conjunction with the comment from @cargocultprogramming to make a functioning tags page.

Thanks!
