Post Statistics Plugin for Pelican

This is a Pelican plugin to calculate various statistics about a post and store them in an article.stats dictionary. You can see this in action in the sidebar on the left of this site.

I wanted to implement the nice little “X min read” thing from Medium - and it turned out that it was easy to provide a few other interesting stats at the same time, for people to use in their templates.

The returned article.stats dictionary contains the following:

For example:

{
    'wc': 2760,
    'fi': '65.94',
    'fk': '7.65',
    'word_counts': Counter({u'to': 98, u'a': 90, ...}),
    'read_mins': 12
}

This allows you to output these values in your templates, like this, for example:

<p title="~{{ article.stats['wc'] }} words">~{{ article.stats['read_mins'] }} min read</p>
<ul>
    <li>Flesch-kincaid Index/ Reading Ease: {{ article.stats['fi'] }}</li>
    <li>Flesch-kincaid Grade Level: {{ article.stats['fk'] }}</li>
</ul>

The word_counts variable is a python Counter dictionary and looks something like this, with each unique word and it’s frequency:

Counter({u'to': 98, u'a': 90, u'the': 83, u'of': 50, u'karma': 50, .....

This can be used to create a tag/word cloud for a post.
