I'm having trouble trying to figure out how to get prolog to spit out a text file where I want it to. I'm currently doing a bunch of operations and then using

tell('output.txt')

to record the output. Now the problem is that when I do this, it creates this file in the SWI \bin\ folder. I was wondering if there's a way to make it create this file in the directory containing the actual .pl file. So even if the file was moved (and it will be), the text file gets created right where the source file is.

Long story short, is there a way to get the location of the source file once the source file has been consulted?

Many Thanks!

I was wondering, I am aware you can use assert to add facts or rules or whatever if you have declared the predicate to be -:dynamic, but this only allows the changes that are made to be kept in that session only, e.g. if you close the prolog window then the database changes are lost. So I was wondering… >>> More

SWI-Prolog tokenize_atom/2 replacement?

as seen on Stack Overflow - Search for 'Stack Overflow'
What I need to do is to break atom to tokens. E. g.: tokenize_string('Hello, World!', L). would unify L=['Hello',',','World','!']. Exactly as tokenize_atom/2 do. But when I try to use tokenize_atom/2 with non-latin letters it fails. Is there any universal replacement or how I can write one? Thanks… >>> More
