Python bindings for GNU libextractor
About libextractor
==================
libextractor is a simple library for keyword extraction. libextractor
does not support all formats but supports a simple plugging mechanism
such that you can quickly add extractors for additional formats, even
without recompiling libextractor. libextractor typically ships with a
dozen helper-libraries that can be used to obtain keywords from common
file-types.
libextractor is a part of the GNU project (http://www.gnu.org/).
Dependencies
============
* python >= 2.3
web site: http://www.python.org/
* libextractor > 0.5
web site: http://gnunet.org/libextractor
* ctypes >= 0.9
web site: http://starship.python.net/crew/theller/ctypes/
* setuptools (optional)
web site: http://cheeseshop.python.org/pypi/setuptools
Performances
============
Surprisingly the original C native library is only 20% faster than
this python ctypes bindings. Here a quick and dirty bench:
The C extract on Extractor test files:
$ time `find Extractor/test -type f -not -name "*.svn*"|xargs extract`
real 0m0.403s
user 0m0.303s
sys 0m0.061s
Same data with the ctypes python bindings:
$ time `find Extractor/test -type f -not -name "*.svn*"|xargs extract.py`
real 0m0.661s
user 0m0.529s
sys 0m0.074s
Install
=======
Using the tarball (as root):
# python setup.py install
Using the egg (as root):
# easy_install Extractor-*.egg
