I am pleased to announce the 0.1.2 version of PySWIP.
PySWIP is a GPL'd Python/SWI-Prolog bridge enabling to query SWI-
Prolog in your Python programs.
PySWIP includes both an (incomplete) SWI-Prolog foreign language
interface and a utity class that makes it easy querying SWI-Python.
Since it uses SWI-Prolog as a shared library and ctypes to access it,
PySWIP doesn't require compilation to be installed.
Example
-------
>>> from pyswip.util import Prolog
>>> prolog = Prolog()
>>> prolog.assertz("father(michael,john)")
>>> prolog.assertz("father(michael,gina)")
>>> list(prolog.query("father(michael,X)"))
[{'X': 'john'}, {'X': 'gina'}]
>>> for soln in prolog.query("father(X,Y)"):
... print soln["X"], "is the father of", soln["Y"]
...
michael is the father of john
michael is the father of gina
Requirements
------------
* Python 2.3 and higher (most probably other versions will also
work).
* ctypes 0.9.9.9 and higher (most probably other versions will
also work).
* SWI-Prolog 5.6.x and higher(most probably other versions will
also work).
* libpl as a shared library.
* Tested only on Linux, should be working for other POSIX and
Win32.
Changes since 0.1.1
-------------------
* Renamed PrologRunner to Prolog.
* Removed query method of Prolog, queryGenerator is renamed as
query.
* Added asserta, assertz and consult methods to Prolog.
* The necessary cleanup is done even if the query generator doesn't
run to the end.
* Errors during the execution of query is caught and PrologError is
raised.
* Many new additions to the core library.
* Added examples directory.
* Added examples, 'coins' and 'draughts'.
* Added Windows installer.
