reader

reader is a Python feed reader library.

It is designed to allow writing feed reader applications without any business code, and without depending on a particular framework.

Features

reader allows you to:

  • retrieve, store, and manage Atom, RSS, and JSON feeds

  • mark articles as read or important

  • add arbitrary tags/metadata to feeds and articles

  • filter feeds and articles

  • full-text search articles

  • get statistics on feed and user activity

  • write plugins to extend its functionality

  • skip all the low level stuff and focus on what makes your feed reader different

…all these with:

  • a stable, clearly documented API

  • excellent test coverage

  • fully typed Python

What reader doesn’t do:

  • provide an UI

  • provide a REST API (yet)

  • depend on a web framework

  • have an opinion of how/where you use it

The following exist, but are optional (and frankly, a bit unpolished):

  • a minimal web interface

    • that works even with text-only browsers

    • with automatic tag fixing for podcasts (MP3 enclosures)

  • a command-line interface

Quickstart

What does it look like? Here is an example of reader in use:

$ pip install reader

>>> from reader import make_reader
>>>
>>> reader = make_reader('db.sqlite')
>>> reader.add_feed('http://www.hellointernet.fm/podcast?format=rss')
>>> reader.update_feeds()
>>>
>>> entries = list(reader.get_entries())
>>> [e.title for e in entries]
['H.I. #108: Project Cyclops', 'H.I. #107: One Year of Weird', ...]
>>>
>>> reader.mark_entry_as_read(entries[0])
>>>
>>> [e.title for e in reader.get_entries(read=False)]
['H.I. #107: One Year of Weird', 'H.I. #106: Water on Mars', ...]
>>> [e.title for e in reader.get_entries(read=True)]
['H.I. #108: Project Cyclops']
>>>
>>> reader.update_search()
>>>
>>> for e in reader.search_entries('year', limit=3):
...     title = e.metadata.get('.title')
...     print(title.value, title.highlights)
...
H.I. #107: One Year of Weird (slice(15, 19, None),)
H.I. #52: 20,000 Years of Torment (slice(17, 22, None),)
H.I. #83: The Best Kind of Prison ()
