Answering to your question #2, I think it shouldn't be a challenge for Perl. I've looked at the
Prolog Tutorial and the syntax doesn't appear to be overly complex. I guess, prolog could be translated in comparable Perl code and then executed? Say, just like what
Ovid did with his AI example, it should be possible to write a Prolog to Perl translator at the least.
In fact, there have already been some steps undertaken in this direction. Take a look at the
Language::Prolog::Interpreter
module. It's
A simple interpreter which doesn't allow infix operators (except for C<:-> and C<,>, both of which are built in).
There's also these
Language::Prolog::* modules. They do appear to be the first courageous step towards accomplishing what you are asking for?
Update:
Ahh, taking
Ovid's lead, let me fix another grammatical error in your post:
1. In your Prolog code, why you did not wrote a question clause ?
Should be...
1. In your Prolog code, why did you not write a question clause ?
Err.. don't take me wrong, I'm not an English grammar wiz as well :). I simply write the way it sounds right ;-).
