app = Feedy('feedy.dat')
@app.add('https://www.djangopackages.com/feeds/packages/latest/rss/')
def djangopackages(info, body):
print("- [{pkgname}]({link})".format(pkgname=info['article_title'], link=info['article_url']))

4. Use plugins
--------------
You can easy developing by using plugins.
For example, you can get shared count in social sns like facebook and pocket.
There are two ways for applying the plugin.
**Apply specified function using decorator**
.. code-block:: python
from feedy_plugins import social_share_plugin
@app.add('http://rss.cnn.com/rss/edition.rss')
@social_share_plugin
def cnn_shared(info, body, social_count):
article = {
'title': info['article_title'],
'pocket': social_count['pocket_count'],
'facebook': social_count['facebook_count'],
}
print(article)
And running:
::
$ feedy main.py app -t cnn_shared -m 2
{'title': 'Searchers locate Flight 804, EgyptAir vice chairman says', 'pocket': 4, 'facebook': 25}
{'title': 'Security fears over French airports', 'pocket': 2, 'facebook': 9}
**Apply all functions with ``.install()``**
.. code-block:: python
from feedy import Feedy
from feedy_plugins import social_share_plugin
from bs4 import BeautifulSoup
app = Feedy(store='feedy.dat', ignore_fetched=True)
app.install(social_shared_plugin) # apply each patterns.
@app.add('http://rss.cnn.com/rss/edition.rss')
def cnn_shared(info, body, social_count):
article = {
'title': info['article_title'],
'pocket': social_count['pocket_count'],
'facebook': social_count['facebook_count'],
}
print(article)
@app.add('https://www.djangopackages.com/feeds/packages/latest/rss/')
def djangopackages(info, body, social_count):
print("- [{pkgname}]({link})".format(pkgname=info['article_title'],
link=info['article_link']))
print(social_count['pocket_count'])
if __name__ == '__main__':
app.run()
5. Using feedy_utils
--------------------
Download images using feedy_utils.
.. code-block:: python
from feedy import Feedy
from feedy_utils import download_image
IMG_DIR = os.path.join(os.path.dirname('.'), 'img')
app = Feedy(store='feedy.dat', ignore_fetched=True)
@app.add('http://rss.cnn.com/rss/edition.rss')
def cnn(info, body):
download_image(body, info['site_url'],
filename="{title}-{i}".format(info['article_title']),
directory=IMG_DIR)
if __name__ == '__main__':
app.run()
Create Plugins
==============
To write a new plugin, simply create decorator like:
.. code-block:: python
def add_information_plugin(callback):
@wraps(callback)
def wrapper(*args, **kwargs):
additional_info = "This is custom plugin."
kwargs['additional_info'] = additional_info
callback(*args, **kwargs)
return wrapper
Happy hacking :)
