Series plugin

The series plugin allows you to join different posts into a series.

In order to mark posts as part of a series, use the :series: metadata:

:series:  NAME_OF_THIS_SERIES

or, in Markdown syntax

Series: NAME_OF_THIS_SERIES

The plugin collects all articles belonging to the same series and provides series-related variables that you can use in your template.

Indexing

By default articles in a series are ordered by date and then automatically numbered.

If you want to force a given order just specify the :series_index: metadata or in Markdown series_index:, starting from 1. All articles with this enforced index are put at the beginning of the series and ordered according to the index itself. All the remaining articles come after them, ordered by date.

The plugin provides the following variables to your templates

* `article.series.name` is the name of the series as specified in the article metadata
* `article.series.index` is the index of the current article inside the series
* `article.series.all` is an ordered list of all articles in the series (including the current one)
* `article.series.all_previous` is an ordered list of the articles published before the current one
* `article.series.all_next` is an ordered list of the articles published after the current one
* `article.series.previous` is the previous article in the series (a shortcut to `article.series.all_previous[-1]`)
* `article.series.next` is the next article in the series (a shortcut to `article.series.all_next[0]`)

For example:

{% if article.series %}
    <p>This post is part {{ article.series.index }} of the "{{ article.series.name }}" series:</p>
    <ol class="parts">
        {% for part_article in article.series.all %}
            <li {% if part_article == article %}class="active"{% endif %}>
                <a href='{{ SITEURL }}/{{ part_article.url }}'>{{ part_article.title }}</a>
            </li>
        {% endfor %}
    </ol>
{% endif %}
