==============

Lovely Stemmer

==============

This package contains a pure python implementation of the snowball

stemmer for german as described under

http://snowball.tartarus.org/algorithms/german/stemmer.html

Here is an example on how to use the stemmer from python::

    >>> from lovely.stemmer import german

    >>> german.stem(u'kaufen')

    u'kauf'

Developement Setup

==================

Run bootstrap::

 python bootstrap.py --distribute

And run buildout::

 ./bin/buildout -N

Test the package::

 ./bin/test

These code check commands should return no output::

 ./bin/pep8

 ./bin/pyflakes

Commandline Usage

=================

There is a commandline script which takes a word per line from

stdin and outputs the stemmed version of the word. For example::

  echo kaufen | ./bin/porter_german

This script can be used to stemm complete (e.g. myspell) dictionary

files too, it strips of any trailing parts after non-word characters.
