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
|
2012-05-06 23:57:03 +00:00
|
|
|
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
|
|
|
|
|
-------------
|
2012-05-07 00:45:44 +00:00
|
|
|
This does depend on lxml so you'll need some C headers in order to install
|
|
|
|
|
things from pip so that it can compile.

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.

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.
