# A quick and dirty plugin for Jekyll by Eli Naeher                                                                               
#                                                                                                                 
# This plugin creates a site.years template variable which allow you to group archive links by year and month.    
# The structure of site.years is:                                                                                 
# site.years = 2001=>[[post1, post2...], [...]], 2002=>[...]                                                
#                                                                                                                 
# Usage should look something like this:                                                                          
# {% for year in site.years %}                                                                                    
#   <h2>Year {{ year.first.first.date | date: "%Y" }}</h2>                                                        
#   {% for month in year %}                                                                                       
#     <h3>Month {{ month.first.date | date: "%B" }}</h3>                                                          
#     {% for post in month %}                                                                                     
#       <a href="{{ post.url">{{ post.title }}</a>                                                                
#     {% endfor %}                                                                                                
#   {% endfor %}                                                                                                  
# {% endfor %}                                                                                                    

class Jekyll::Site
        alias :site_payload_without_tiered_archives :site_payload

        def site_payload
                data = site_payload_without_tiered_archives
                data['site']['years'] = TieredArchives::find_years(self.posts.reverse)
                data
        end
end

module TieredArchives

        def self.find_years(posts)
          posts.group_by {|post| post.date.year}.values.map {|year| year.group_by {|post| post.date.month}.values};
        end

end

I cannot output post date as day of month; like here http://mnmlist.com/

Can you help me?

I Found solution:

{% for year in site.years %}
    <h2>{{ year.first.first.date | date: "%Y" }}</h2>
    {% for month in year %}
        <h3>{{ month.first.date | date: "%B" }}</h3>
        <dl>
        {% for post in month %}
            <dt>{{post.date | date: "%d"}}</dt>         
            <dd>
                <a href="{{ post.url}}">{{ post.title }}</a>
            </dd>
        {% endfor %}
        </dl>
    {% endfor %}
{% endfor %}

How can I sort the months? In my website, the output of the original suggested code is:

2011
 Maio 
 Novembro
 Junho
 Dezembro
 Fevereiro
 Agosto
 Março
 Setembro
 Abril
 Outubro
2012
 Maio

 Julho 
 Fevereiro

I am using

        <ul class="list-type2">
          {% for year in site.years %}                                                                                    
          <li>{{ year.first.first.date | date: "%Y" }}
        <ul>
          {% for month in year %}                                                                                       
          <li><a href="/{{ year.first.first.date | localize: '%Y'}}/{{ month.first.date | localize: '%m'}}/">
              {{ month.first.date | localize: "%B" }}</a></li>
          {% endfor %}                                                                                                
        </ul>
              </li>
          {% endfor %}
        </ul>
