Redone port of Readability API in Python
Project description
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:
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:
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.
