Static comments

This plugin allows you to add static comments to an article. By default the plugin looks for the comments of each article in a local file named comments/{slug}.md, where {slug} is the value of the slug tag for the article. The comments file should be formatted using markdown.

Set the STATIC_COMMENTS parameter to True to enable the plugin. Default is False.

Set the STATIC_COMMENTS_DIR parameter to the directory where the comments are located. Default is comments.

On the template side, you just have to add a section for the comments to your article.html, as in this example::

{% if STATIC_COMMENTS %}
<section id="comments" class="body">
<h2>Comments!</h2>
{{ article.metadata.static_comments }}
</section>
{% endif %}
