<p>This module can be used to generate web feeds in both ATOM and RSS format. It
|
||
has support for extensions. Included is for example an extension to produce
|
||
Podcasts.</p>
|
||
<p>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.</p>

<p><strong>Prebuild packages</strong></p>
|
||
<p>If your distribution includes this project as package, like Fedora Linux does,
|
||
you can simply use your package manager to install the package. For example:</p>
|
||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>$ dnf install python3-feedgen
|
||
</pre></div>
|
||
</div>
|
||
<p><strong>Using pip</strong></p>
|
||
<p>You can also use pip to install the feedgen module. Simply run:</p>
|
||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>$ pip install feedgen

<p>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:</p>
|
||
<ul class="simple">
|
||
<li>Provide the data for that element as keyword arguments</li>
|
||
<li>Provide the data for that element as dictionary</li>
|

<li>Provide a list of dictionaries with the data for several elements</li>

<h2><a class="toc-backref" href="#id5">Add Feed Entries</a><a class="headerlink" href="#add-feed-entries" title="Permalink to this headline">¶</a></h2>
|
||
<p>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:</p>
|
||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="gp">>>> </span><span class="n">fe</span> <span class="o">=</span> <span class="n">fg</span><span class="o">.</span><span class="n">add_entry</span><span class="p">()</span>

|
||
</pre></div>
|
||
</div>
|
||
<p>The FeedGenerators method <cite>add_entry(…)</cite> 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.</p>
|
||
</div>
|
||
<div class="section" id="extensions">
|
||
<h2><a class="toc-backref" href="#id6">Extensions</a><a class="headerlink" href="#extensions" title="Permalink to this headline">¶</a></h2>
|
||
<p>The FeedGenerator supports extension to include additional data into the XML
|
||
structure of the feeds. Extensions can be loaded like this:</p>
|
||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="gp">>>> </span><span class="n">fg</span><span class="o">.</span><span class="n">load_extension</span><span class="p">(</span><span class="s1">'someext'</span><span class="p">,</span> <span class="n">atom</span><span class="o">=</span><span class="kc">True</span><span class="p">,</span> <span class="n">rss</span><span class="o">=</span><span class="kc">True</span><span class="p">)</span>
|
||
</pre></div>
|
||
</div>
|
||
<p>This will try to load the extension “someext” from the file <cite>ext/someext.py</cite>.
|
||
It is required that <cite>someext.py</cite> contains a class named “SomextExtension” which
|
||
is required to have at least the two methods <cite>extend_rss(…)</cite> and
|
||
<cite>extend_atom(…)</cite>. Although not required, it is strongly suggested to use
|
||
<cite>BaseExtension</cite> from <cite>ext/base.py</cite> as superclass.</p>
|
||
<p><cite>load_extension(‘someext’, …)</cite> will also try to load a class named
|
||
“SomextEntryExtension” for every entry of the feed. This class can be located
|
||
either in the same file as SomextExtension or in <cite>ext/someext_entry.py</cite> which
|
||
is suggested especially for large extensions.</p>
|
||
<p>The parameters <cite>atom</cite> and <cite>rss</cite> control if the extension is used for ATOM and
|
||
RSS feeds, respectively. The default value for both parameters is <cite>true</cite>
|
||
meaning the extension is used for both kinds of feeds.</p>
|
||
<p><strong>Example: Producing a Podcast</strong></p>
|
||
<p>One extension already provided is the podcast extension. A podcast is an RSS
|
||
feed with some additional elements for ITunes.</p>
|
||
<p>To produce a podcast simply load the <cite>podcast</cite> extension:</p>
|

</div>
|
||
<p>If the FeedGenerator class is used to load an extension, it is automatically
|
||
loaded for every feed entry as well. You can, however, load an extension for a
|
||
specific FeedEntry only by calling <cite>load_extension(…)</cite> on that entry.</p>
|
||
<p>Even if extensions are loaded, they can be temporarily disabled during the feed
|
||
generation by calling the generating method with the keyword argument
|
||
<cite>extensions</cite> set to <cite>False</cite>.</p>
|
||
<p><strong>Custom Extensions</strong></p>
|
||
<p>If you want to load custom extensions which are not part of the feedgen
|
||
package, you can use the method <cite>register_extension</cite> instead. You can directly
|
||
pass the classes for the feed and the entry extension to this method meaning
|
||
that you can define them everywhere.</p>
