Question

我正在尝试从命令行执行序言脚本。我的尝试基于How to run SWI-Prolog from the command line?的发现但这不适用于任何不平凡的示例（即除“ hello world”示例以外的任何示例）。

:- initialization(main, program).

main :-
    parent(pam,bob).
    parent(tom,bob).
    parent(tom,liz).
    parent(bob,ann).
    parent(bob,pat).
    parent(pat,jim).
    parent(X,jim).
    halt.

我用$ swipl -q -s temp.p执行此操作，并收到以下错误消息

Warning: temp.p:10:
    Singleton variables: [X]
ERROR: temp.p:11:
    No permission to modify static procedure `halt/0'
    Defined at /opt/local/lib/swipl/boot/init.pl:3867

我如何从命令行执行此操作，获取结果，但不保留给代表？

您最大的问题是您的源代码有很多问题。我已经像这样修复了它们：

现在程序没有错误，您可以通过在命令行上提供目标来执行它而无需返回到REPL：

parent(pam,bob).
parent(tom,bob).
parent(tom,liz).
parent(bob,ann).
parent(bob,pat).
parent(pat,jim).

main :-
    parent(X,jim),
    format('~a is the parent of jim~n', [X]),
    halt.

如何从命令行运行prolog文件，而不是替换为repl？
