Pelican Jinja Date extension and conditional for comparing current datetime to object date.

Pelican Jinja Date Extension

This will format python datetime as a string to be used within jinja conditionals for comparing current date to article date using pelican app.

1. Create a file named jinjaext.py
2. paste the following snippet

def convertdate(datetime, format='%a-%d-%m-%Y'):
	return datetime.date().strftime(format)

3. Add the following line to your config file

import jinjaext
from datetime import datetime

# this line will output your current datetime
CURRDATE = datetime.now().strftime('%a-%d-%m-%Y')

#this line adds your new jinja extension filter
JINJA_FILTERS =     {
                    'convertdate': jinjaext.convertdate , 
                    }

4. Use the following jinja template loop in your theme to compare post date to current date time

       <p> 
{% if article.date|convertdate < CURRDATE %}
this is an old post
{% elif article.date|convertdate == CURRDATE %}
this was posted today
{% else %}
this is a future post
{% endif %}
       </p>

I got the error when trying to import the jinjaext. We probably should load jinjaext.py using absolute path. In pelicanconf.py, add these lines

import imp

jinjaext = imp.load_source('jinjaext', './jinjaext.py')

JINJA_FILTERS = {
'convertdate': jinjaext.convertdate ,
}
