PySWIP 0.2.2
|
|
============
|
|
|
|
PySWIP is a GPL'd Python - SWI-Prolog bridge enabling to query SWI-Prolog
|
|
in your Python programs. It features an (incomplete) SWI-Prolog foreign
|
|
language interface, a utility class that makes it easy querying with Prolog
|
|
and also a Pythonic interface.
|
|
|
|
Since PySWIP uses SWI-Prolog as a shared library and ctypes to access it,
|
|
it doesn't require compilation to be installed.
|
|
|
|
Note that this version of PySWIP is slightly incompatible with 0.1.x versions.
|
|
|
|
Requirements:
|
|
-------------
|
|
|
|
* Python 2.3 and higher.
|
|
* ctypes 1.0 and higher.
|
|
* SWI-Prolog 5.6.x and higher (most probably other versions will also work).
|
|
* libpl as a shared library.
|
|
* Works on Linux and Win32, should work for all POSIX.
|
|
|
|
News
|
|
----
|
|
|
|
* Importing ``pyswip`` automatically initializes SWI-Prolog.
|
|
* Fixed a bug with querying lists with the new interface.
|
|
|
|
Example (Using Prolog):
|
|
-----------------------
|
|
|
|
>>> from pyswip 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
|
|
|
|
Since version 0.1.3 of PySWIP, it is possible to register a Python function as a Prolog predicate through SWI-Prolog's foreign language interface.
|
|
|
|
Example (Foreign Functions):
|
|
----------------------------
|
|
|
|
from pyswip import Prolog, registerForeign
|
|
|
|
def hello(t):
|
|
print "Hello,", t
|
|
hello.arity = 1
|
|
|
|
registerForeign(hello)
|
|
|
|
prolog = Prolog()
|
|
prolog.assertz("father(michael,john)")
|
|
prolog.assertz("father(michael,gina)")
|
|
list(prolog.query("father(michael,X), hello(X)"))
|
|
|
|
Outputs:
|
|
Hello, john
|
|
Hello, gina
|
|
|
|
Since version 0.2, PySWIP contains a 'Pythonic' interface which allows writing predicates in pure Python (*Note that interface is experimental.*)
|
|
|
|
Example (Pythonic interface):
|
|
-----------------------------
|
|
|
|
from pyswip import Functor, Variable, Query
|
|
|
|
assertz = Functor("assertz", 2)
|
|
father = Functor("father", 2)
|
|
|
|
call(assertz(father("michael","john")))
|
|
call(assertz(father("michael","gina")))
|
|
|
|
X = Variable()
|
|
q = Query(father("michael",X))
|
|
while q.nextSolution():
|
|
print "Hello,", X.value
|
|
|
|
Outputs:
|
|
Hello, john
|
|
Hello, gina
