- macro def m[I1, I2, A, B](dsl: IN2_02[I1, I2, A, B]): InputMolecule_2_02[I1, I2, A, B]
Macro creation of input molecule awaiting 2 inputs from user-defined DSL structure with 2 output attributes (arity 2).
Macro creation of input molecule awaiting 2 inputs from user-defined DSL structure with 2 output attributes (arity 2).
Molecules are build by adding one or more attributes to an initial namespace likePerson
from the example below.
Applying the?
marker to attributes changes the semantics of a molecule to become an "input molecule" that awaits input at runtime for the attributes marked with?
.
Once the input molecule has been resolved with input, we can call various actions on it, likeget
that retrieves matching data from the database.// Apply `?` to `age` and `score` attributes to create input molecule. // Input attributes can be tacit or mandatory val personAgeScore = m(Person.name.age_(?).score(?)) // At runtime `age` and `score` values are applied to get the Person's name and score. // Since `score` was mandatory (without underscore), its value is also returned. personAgeScore(42, 7).get.head === ("Ben", 7)

For arity-many molecules, data structures are returned as tuples. But for arity-1 molecules (like the example having only 1 output attribute,
name
) there's no need for a tuple, so values type-safely matching the attribute are returned directly in the list.- I1
