Thanks so much for your review @amimart. Indeed, it gets tricky and tests are definitely essential. |
Scope
This PR introduces implements the standard predicate
string_bytes/3as specified by #497 and functionally aligned with the SWI-Prolog implementation (except for errors).Implementation details
The PR comes with many changes, my apologies for that. But the implementation required a refactoring of how prolog terms are processed during conversion to and from byte list representations. This involved introducing support for various encodings (e.g., UTF-8).
Additionally, a first step towards standardization of error messages has been undertaken. This primarily involves transitioning from text-described errors to errors represented by Prolog terms. These terms are highly compatible with the conventions outlined in SWI-Prolog's documentation. This foundation for the approach exists in Itchiban Prolog.
Finally, this PR lays the groundwork for implementing additional conversion predicates, particularly those related to
base64andbase58encodings.Summary by CodeRabbit
