Description:
------------
The pysfst module contains Python bindings for the API of SFST, the
Stuttgart Finite State Transducer Tools. The source URL is
http://mypage.bluewin.ch/tarnold/pysfst/pysfst-0.0.1.tar.bz2
The interface was generated using SWIG and is included in the distribution.
The hardest part for now was to overload the stream oriented API of the C++
library with a more pythonic string list oriented one using pipes.
SFST itself (see dependencies below) comes with a german morphology called
SMOR. An excerpt from the doctests for pysfst is best suited to demonstrate
what pysfst/SFST is for:
This is the lexical example entry (the german name for the bird called
"bullfinch" in english) we'll use for now:
<Base_Stems>Dompfaff<NN><base><nativ><NMasc_es_en>
Often the result of analyze_string is ambiguous. In that case, analyze_string
returns any matching disambiguation in a list.
>>> smor_transducer.analyze_string('Dompfaff')
['Dompfaff<+NN><Masc><Dat><Sg>', 'Dompfaff<+NN><Masc><Nom><Sg>',
'Dompfaff<+NN><Masc><Akk><Sg>']
Word form generation is sometimes ambiguous, too. Here we generate our sample
bird in the genitive singular case which optionially allows the elision of an
'e'.
>>> smor_transducer.generate_string('Dompfaff<+NN><Masc><Gen><Sg>')
['Dompfaffs', 'Dompfaffes']

Other Comments:
---------------
I did not yet inform Helmut Schmid, the author of SFST, about pysfst. I
planned to do it when/if the project page is up.
