Compat8.2.0

[allComputableThings]

PL_STRING has changed in SWI-Prolog.h.

• Synchronized type constants with SWI-Prolog.h update for broken compatibility changes in SWI-Prolog.h. Update to swi-prolog >= 0.8.2 is required (and the default apt for Ubuntu >= 14.04).
  • Fix incorrect REP_* constants.
  • Fixed https://github.com/yuce/pyswip/issues/92 (C assert)
  • Fixed https://github.com/yuce/pyswip/issues/90 (quoted string)

[allComputableThings]

Added check for required PL_version.

Now with compatibility for 7.x.x to 8.3.x

Tests don't pass on 7.6.3 since PL_version doesn't seem to exist in that version:

tests/test_examples.py:31: in <module>
    from pyswip import *
pyswip/__init__.py:29: in <module>
    from pyswip.prolog import Prolog
pyswip/prolog.py:28: in <module>
    from pyswip.core import *
pyswip/core.py:576: in <module>
    PL_version = _lib.PL_version
/usr/lib/python3.6/ctypes/__init__.py:361: in __getattr__
    func = self.__getitem__(name)
/usr/lib/python3.6/ctypes/__init__.py:366: in __getitem__
    func = self._FuncPtr((name_or_ordinal, self))
E   AttributeError: /usr/lib/libswipl.so.7.6: undefined symbol: PL_version

Maybe setting PL_version to something like 70000 if _lib.PL_version does not exist would work better.

Sounds good. Will do it tomorrow

It is done. By the way, does the test fail in the continuous integration somewhere? I didn't see the error you reported? (All I see is https://github.com/yuce/pyswip/pull/93 , which said all tests pass).

Not sure why the CI report doesn't show up... Thanks for the PR, tests pass on local.

Hi, This issue seems to pop up again : This python script fails with the same error (/build/swi-prolog-hvyroz/swi-prolog-9.0.0-1-g0757fd884/src/pl-fli.c:2637: PL_put_chars: Assertion failed: 0): from pyswip import Prolog prolog = Prolog() prolog.assertz("father(joe,john)") Did somebody face the same issue, and do you know how to solve the problem?

Thank you in advance for your help :)

Here are the versions of my environment: Ubuntu 20.04.5 LTS pyswip: 0.2.10 swi-prolog: 9.0.0 for x86_64-linux
