Public predicates

dif/2

Sets a constraint that is true iff the two terms are different.

Compilation flags:
static
Template:
dif(Term1,Term2)
Mode and number of proofs:
dif(+term,+term) - zero_or_one

dif/1

Sets a set of constraints that are true iff all terms in a list are different.

Compilation flags:
static
Template:
dif(Terms)
Mode and number of proofs:
dif(+list(term)) - zero_or_one

freeze/2

Delays the execution of a goal until a variable is bound.

Compilation flags:
static
Template:
freeze(Variable,Goal)
Meta-predicate template:
freeze(*,0)
Mode and number of proofs:
freeze(+term,+callable) - zero_or_more

frozen/2

Unifies Goal with the goal delayed by Variable. When no goals are frozen on Variable, Goal is unified with true.

Compilation flags:
static
Template:
frozen(Variable,Goal)
Mode and number of proofs:
frozen(@var,--callable) - one

when/2

Calls Goal when Condition becomes true. The portable conditions are: nonvar/1, ground/1, (,)/2, and (;)/2.

Compilation flags:
static
Template:
when(Condition,Goal)
Meta-predicate template:
when(*,0)
Mode and number of proofs:
when(+callable,+callable) - zero_or_more
