What is the best way to normalize whitespace characters (space, newline, tab) in a Prolog atom, e.g. in SWI-Prolog. I.e. I would like to have a rule:
normalize_space_in_atom(+Atom1, -Atom2) such that Atom2
SWI Prolog provides normalize_space/2, and so you could define your predicate as follows:
I’ve tried this out with SWI Prolog 5.7.5 and it appears to work. You could add more error handling if you wish.
