Ctrl-C not working #115

Open pampelmuse76 opened 3 years ago

pampelmuse76 commented 3 years ago

A python program, which does not determine in the prolog part, cannot be stopped by entering Ctrl-C.

!/usr/bin/python

from pyswip import Prolog prolog = Prolog() prolog.assertz(""" f(X) :- X #> 0, f(X) """) for result in prolog.query("f(X)"): print(result["X"])

Python 3.9.1 pyswip 0.2.10 SWI-Prolog version 8.2.3 for x86_64-linux

Did you try: prolog.query("f(X)", catcherrors=False) ?

Yes, with catcherrors=False and catcherrors=True. Neither works.

Sending a kill signal (TERM) to the process id is working (it determines the program)
