How to Iterate Over Files in a Directory

[sagiv10]

Hi :)
How can I iterate over all the files in a given directory in the Logtalk, given the path to that directory? I would like to read or process each file found in that directory. What is the best way to achieve this in Logtalk?

Using the os library directory_files/3 predicate?

Hi thank you, i tried this, and it doesn't work. Is there another way?

What exactly did you try? The os::directory_files/3 returns a list of files. You simply need to walk that list either with your own list traversal predicate (trivial to write) or one of the meta library map predicates. If you don't know yet how to do that, I suggest taking the time to read a Prolog tutorial on list processing.
