SWI-Prolog: splitting text atom into list of characters

Question

Very simple question: I know there are plenty of ways to split an atom, eg 'example atom' on some delimiter, eg ' ' -> ['example', 'atom'] but is there a way to split up every character? Eg ['e', 'x', 'a', ... 'o', 'm']. I've tried

atomic_list_concat(List, '', Atom),

but that generates the error

ERROR: atomic_list_concat/3: Domain error: `non_empty_atom' expected, found `'

What would you recommend?

Answer 1

Do you want something like this?

?- atom_chars(hello, X).
X = [h, e, l, l, o].
