breadability - another readability Python port
===============================================
I've tried to work with the various forks of some ancient codebase that ported
`readability`_ to Python. The lack of tests, unused regex's, and commented out
sections of code in other Python ports just drove me nuts.
I put forth an effort to bring in several of the better forks into one
codebase, but they've diverged so much that I just can't work with it.
So what's any sane person to do? Re-port it with my own repo, add some tests,
infrastructure, and try to make this port better. OSS FTW (and yea, NIH FML,
but oh well I did try)
This is a pretty straight port of the JS here:
- http://code.google.com/p/arc90labs-readability/source/browse/trunk/js/readability.js#82
Installation
-------------
This does depend on lxml so you'll need some C headers in order to install
things from pip so that it can compile.
::
sudo apt-get install libxml2-dev libxslt-dev
pip install breadability
Usage
------
cmd line
~~~~~~~~~
::
$ breadability http://wiki.python.org/moin/BeginnersGuide
Options
``````````
- b will write out the parsed content to a temp file and open it in a
browser for viewing.
- f will override the default behaviour of getting an html fragment (<div>)
and give you back a full <html> document.
- v will output in verbose debug mode and help let you know why it parsed
how it did.
Using from Python
~~~~~~~~~~~~~~~~~~
::
from breadability.readable import Article
readable_article = Article(html_text, url=url_came_from)
print readable_article
Work to be done
---------------
Yep, I've got some catching up to do. I don't do pagination, I've got a lot of
custom tweaks I need to get going, there are some articles that fail to parse.
I also have more tests to write on a lot of the cleaning helpers, but
hopefully things are setup in a way that those can/will be added.
Fortunately, I need this library for my tools:
- https://bmark.us
- http://readable.bmark.us
so I really need this to be an active and improving project.
Off the top of my heads todo list:
- Support metadata from parsed article [url, confidence scores, all
candidates we thought about?]
- More tests, more thorough tests
- More sample articles we need to test against in the test_articles
- Tests that run through and check for regressions of the test_articles
- Tidy'ing the HTML that comes out, might help with regression tests ^^
- Multiple page articles
- Performance tuning, we do a lot of looping and re-drop some nodes that
should be skipped. We should have a set of regression tests for this so
that if we implement a change that blows up performance we know it right
away.
- Get up on pypi along with the rest of the ports
- More docs for things, but sphinx docs and in code comments to help
understand wtf we're doing and why. That's the biggest hurdle to some of
this stuff.
Helping out
------------
If you want to help, shoot me a pull request, an issue report with broken
urls, etc.
You can ping me on irc, I'm always in the `#bookie` channel in freenode.
