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`](https://github.com/lkiesow/pyFeedGenerator/blob/master/feedgenerator/__main__.py#L36).
