Jinja2 Content

This plugin allows the use of Jinja2 directives inside your pelican articles and pages. This template rendering is done before the final html is generated, i.e. before your theme's article.html is applied. This means the context and jinja variables usually visible to your article template ARE NOT available at this time.

All code that needs those variables (article, category, etc) should be put inside the theme's template logic. As such, the main use of this plugin is to automatically generate parts of your articles.

Example

One usage is to embed repetitive html code into Markdown articles. Since Markdown doesn't care for layout, if anything more sophisticated than just displaying an image is necessary, one is forced to embed html in Markdown articles (at the very least, hardcode <div> tags and then fix it with the theme's CSS). However, with jinja2content, one can do the following.

File my-cool-article.md

# My cool title

My cool content.

{% from 'img_desc.html' import img_desc %}
{{ img_desc("/images/my-cool-image.png",
    "This is a cool tooltip",
    "This is a very cool image.") }}

Where file img_desc.html contains:

{% macro img_desc(src, title='', desc='') -%}
<div class="img-desc">
  <p><img src="{{ src }}" title="{{ title }}"></p>
  {% if desc %}
  <p><em>{{ desc }}</em></p>
  {% endif %}
</div>
{%- endmacro %}

In this way, Markdown articles have more control over the content that is passed to the theme's article.html, without the need to pollute the Markdown with html. Another added benefit is that now img_desc is reusable across articles.

Note that templates rendered with jinja2content can contain Markdown as well as html, since they are added before the Markdown content is converted to html.

Notes

• Only Markdown supported at this moment. Adding .rst support shouldn't be too hard, and you can ask for it here.
• All templates included in this way must be placed in your theme's templates directory.
• This plugin is intended to replace pelican-jinj2content which hasn't been developed in a while and generated empty <p> tags in the final html output.
