============= Feedgenerator

This module can be used to generate web feeds in both ATOM and RSS format. The included PodcastGenerator can furthermore generate all of Apples RSS extension for Podcasts.

It is licensed under the terms of both, the FreeBSD license and the LGPLv3+. Choose the one which is more convenient for you. For more details have a look at license.bsd and license.lgpl.

Create a Feed

To create a feed simply instantiate the FeedGenerator class and insert some data::

>>> from feedgen.feed import FeedGenerator
>>> fg = FeedGenerator()
>>> fg.id('http://lernfunk.de/media/654321')
>>> fg.title('Some Testfeed')
>>> fg.author( {'name':'John Doe','email':'john@example.de'} )
>>> fg.link( href='http://example.com', rel='alternate' )
>>> fg.logo('http://ex.com/logo.jpg')
>>> fg.subtitle('This is a cool feed!')
>>> fg.link( href='http://larskiesow.de/test.atom', rel='self' )
>>> fg.language('en')

Note that for the methods which set fields that can occur more than once in a feed you can use all of the following ways to provide data:

• Provide the data for that element as keyword arguments
• Provide the data for that element as dictionary
• Provide a list of dictionaries with the data for several elements

Example::

>>> fg.contributor( name='John Doe', email='jdoe@example.com' )
>>> fg.contributor({'name':'John Doe', 'email':'jdoe@example.com'})
>>> fg.contributor([{'name':'John Doe', 'email':'jdoe@example.com'}, ...])

Generate output

After that you can generate both RSS or ATOM by calling the respective method::

>>> atomfeed = fg.atom_str(pretty=True) # Get the ATOM feed as string
>>> rssfeed  = fg.rss_str(pretty=True) # Get the RSS feed as string
>>> fg.atom_file('atom.xml') # Write the ATOM feed to a file
>>> fg.rss_file('rss.xml') # Write the RSS feed to a file

---

Add Feed Entries

To add entries (items) to a feed you need to create new FeedEntry objects and append them to the list of entries in the FeedGenerator. The most convenient way to go is to use the FeedGenerator itself for the instantiation of the FeedEntry object::

>>> fe = fg.add_entry()
>>> fe.id('http://lernfunk.de/media/654321/1')
>>> fe.title('The First Episode')

The FeedGenerators method add_entry(...) without argument provides will automatically generate a new FeedEntry object, append it to the feeds internal list of entries and return it, so that additional data can be added.

Produce a Podcast

A podcast is an RSS feed with some additional elements for ITunes. The feedgen has a PodcastGenerator class as extension to the default FeedGenerator which you can use to set these additional fields.

To produce a podcast simply do something like this::

>>> from feedgen.podcast import PodcastGenerator
>>> fg = PodcastGenerator()
...
>>> fg.podcast_str(pretty=True)
>>> fg.podcast_file('podcast.xml')

For the episodes of the podcast you should also use PodcastEntry instead of FeedEntry. However, if you use the add_entry(...) method to generator the entry objects, it will take care of that for you.

Of cause you can still produce a normal ATOM or RSS feed, even if you use the PodcastGenerator using the {atom,rss}_{str,file} methods.

Testing the Generator

You can test the module by simply executing::

%> pythom -m feedgen 

If you want to have a look at the code for this test to have a working code example for a whole feed generation process, you can find it in the __main__.py.
