Rebuilding SerialSeb.com – Serials

Edit

You may have noticed a list of other blog entries in this serial just above (provided I don’t update the design again).

One thing I wanted to do was to automatically group posts together that are part of one story arc. I call those serials.

To do that, each of the posts in a serial have an additional instruction in the front-matter metadata.

One of the powerful features of Liquid Templates is its capacity to use extended metadata you define in each post, and make it available at templating time.

For the list of entries in the serial, i created a new include file in _includes/serial/toc.html, that creates the master list of all posts part of a serial.

First, it’s included in the template for a blog post, somewhere in _layouts/post.html.

{%include serial/toc.html post=page %}

Here, i assign the post variable to the page object, so I can reuse the same TOC be it that I’m in a page or enumerating over posts.


{%if include.post.serial %}

{% assign postsInSerial = site.posts | where: "serial", include.post.serial | reverse %}
Part of a serial:
<ol>
{% for post in postsInSerial %}
{%assign cutoffTitle = post.title %}
  <li>
    {%if post.url == include.post.url%}<b>{{cutoffTitle}}{%endif%}</b>
    {%if post.url != include.post.url%}<a href="{{post.url}}">{{cutoffTitle}}</a>{%endif%}
  </li>
{%endfor%}
</ol>
<hr/>
{%endif%}

Filters like sort, reverse and where are used to filter out from the post collections, but they only work if you assign the filtered list to a new variable. If you try it in the for it just doesn’t work. That’s 12 hours lost right there!
