Compilation flags:
static
Template:
listing(Spec)
Mode and number of proofs:
listing(+predicate_indicator) - one_or_error
listing(+non_terminal_indicator) - one_or_error
listing(+callable) - one_or_error
Exceptions:
Spec is not ground:
instantiation_error
Spec is ground but not a valid predicate indicator:
type_error(predicate_indicator,Spec)
Spec is ground but not a valid non-terminal indicator:
type_error(non_terminal_indicator,Spec)
Spec is a predicate indicator but not a visible predicate:
existence_error(predicate,Spec)
Spec is a non-terminal indicator but not a visible non-terminal:
existence_error(non_terminal,Spec)
Spec is a callable term with a Functor/Arity indicator but not a visible predicate:
existence_error(predicate,Functor/Arity)
Spec is a predicate indicator of a visible predicate but not a dynamic predicate:
permission_error(access,predicate,Spec)
Spec is a non-terminal indicator of a visible non-terminal but not a dynamic non-terminal:
permission_error(access,non_terminal,Spec)
Spec is a callable term for a visible predicate with a Functor/Arity indicator but not a dynamic predicate:
permission_error(access,predicate,Functor/Arity)
