5f1f07e5a1 Add --no-add-history flag 
Flag prevents the input stream from saving terms to ~/.scryer_history
when set. Use the flag when running tests to increase test isolation.

9f864574de ADDED: "f" to enumerate the next 5 solutions, similar to GUPU. 2022-03-02 21:05:49 +01:00

102adb3544 ADDED: "a" to enumerate all solutions 
Example:

    ?- member(X, "hello").
    %@    X = h   <-- press "a"
    %@ ;  X = e
    %@ ;  X = l
    %@ ;  X = l
    %@ ;  X = o
    %@ ;  false.
