We have support for defining your own functions. Functions can take in any type of argument. Below is an example of the syntax:
fn myFn(x) {
return x
}
As you can see above myFn just returns whatever it is given.
KCL uses keyword arguments:
// If you declare a function like this
fn add(left, right) {
return left + right
}
// You can call it like this:
total = add(left = 1, right = 2)
Functions can also declare one unlabeled arg. If you do want to declare an unlabeled arg, it must be the first arg declared.
// The @ indicates an argument is used without a label.
// Note that only the first argument can use @.
fn increment(@x) {
return x + 1
}
fn add(@x, delta) {
return x + delta
}
two = increment(1)
three = add(1, delta = 2)
