SWI-Prolog - show long list

Question

I\'m using SWI-Prolog and I\'m trying to print a list but if the list has more than 9 items - it look like that -

[1, 15, 8, 22, 5, 19, 12, 25, 3|...] 
         


        

Answer 1

I've found two ways.

---

1.

?- set_prolog_flag(answer_write_options,[max_depth(0)]).
true.

Then do your command that is printing a truncated list.

(set_prolog_flag documentation)

---

2.

?- atom_chars(goodbye_prolog, X) ; true.

(AllOutput documentation)

Put ; true. at the end of the call that results in a long list. Then push the w key on your keyboard. The result is:

?- sudoku([_,_,2,3,_,_,_,_,_,_,_,_,3,4,_,_], Solution); true.
Solution = [4, 1, 2, 3, 2, 3, 4, 1, 1|...] [write]
Solution = [4, 1, 2, 3, 2, 3, 4, 1, 1, 2, 3, 4, 3, 4, 1, 2] ;
true.
