Writing posts

Posts mainly contain 2 sections. Config section and the Template section. All data inside two --- defines the config and are validated as YAML data. You can set your post related attributes here. In template section you can use Jinja2 templates or Markdown in {% markdown %} and {% endmarkdown %} blocks (You could ignore these blocks if layout is defined in the metadata section).

As per Voldemort's default configuration, all base templates should be in layout and include directories. This is not a hard limitation, but kept for preserving the meaning. Posts are written in a directory named posts. For example, we have a directory structure as shown below

layout/
	listing.html
	post.html
include/
	navigation.html
posts/
	voldemort-is-awesome.markdown
index.html
css/
	screen.css
	pygments.css

And we have the following data in layout/listing.html

<!DOCTYPE html>
<html lang="en-US">

<head>
<title>foobarnbaz.com - {{ page.title }}</title>
{% include "head-common.html" %}
</head>

<body>
<section class="page-content">
{% block content %}{% endblock %}
</section>
</body>
</html>

and include/header.html contains

<meta charset="UTF-8" />
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<meta name="author" content="Sreejith K" />

<link rel="alternate" href="http://feeds2.feedburner.com/foobarnbaz"
  title="foobarnbaz.com" type="application/atom+xml" />
<link rel="stylesheet" href="/css/screen.css" type="text/css" />
<link rel="stylesheet" href="/css/pygments.css" type="text/css" />
<link href='/images/layout/favicon.ico' rel='shortcut icon' type='image/ico' />

We will be able to write the following index.html which generates the front page of your blog with all the posts, paginated with the value provided in settings.yaml (defaults to 5).

---
paginate: true
---
{% extends "listing.html" %}
{% block content %}

{% for post in paginator.posts %}
<article class="excerpt">
<header>
<h1><a href="{{ post.url }}">{{ post.title }}</a></h1>
<time datetime="{{ post.date | date_to_string }}" pubdate="pubdate">
{{ post.date.strftime("%b %d, %Y") }}
</time>
</header>

{% if loop.first %}
{{ post.content }}
<p class="full-post"><a href="{{ post.url }}#comments">comments...</a></p>
{% else %}
<p>{{ post.content }}</p>
<p class="full-post"><a href="{{ post.url }}">full post...</a></p>
{% endif %}

</article>
{% endfor %}
{% endblock %}

And our sample post posts/voldemort-is-awesome.markdown,

---
title: Voldemort
date: '02-10-2011'
time: '10:45'
layout: 'post.html'
---
