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 code base, 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:
This does depend on lxml so you'll need some C headers in order to install things from pip so that it can compile.
.. code-block:: bash
$ [sudo] apt-get install libxml2-dev libxslt-dev
$ [sudo] pip install git+git://github.com/bookieio/breadability.git
.. code-block:: bash
$ nosetests-2.6 tests && nosetests-3.2 tests && nosetests-2.7 tests && nosetests-3.3 tests
Command line
.. code-block:: bash
$ 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.
- **d** will write out debug scoring statements to help track why a node was
chosen as the document and why some nodes were removed from the final
product.
- **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.
Python API
~~~~~~~~~~
.. code-block:: python
from __future__ import print_function
from breadability.readable import Article
if __name__ == "__main__":
document = Article(html_as_text, url=source_url)
print(document.readable)
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://r.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.
- 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.
