Composing with Functions - Feature request.

[sirinath]

Is it possible to have ability to map multiple Vars to be redirected to a function. When all the parameters a variable the function is called and results passed on.

Uhh you mean like this

import rx._
val a = Var(1); val b = Var(2)
val c = Rx{ a() + b() }
println(c()) // 3
a() = 4
println(c()) // 6

[sirinath]

What I meant is

import rx._

val f = (a: Int, b: Int) => a + b

val f1 = Fun(f)

val a = Var(1); val b = Var(2)
val c = Rx{ f1(a, b) }

println(c()) // 3
a() = 4
println(c()) // 6

f can be any function I want to re use. I don't see why you closed this.

I closed it because it already works. Did you even try it?

[sirinath]

Not yet. I was going through the docs. It was silent on how to integrate existing code in the middle of a dataflow. I thought this did not exist. Any way the initial code you have given above also does not show how to pipe variable a and b into an existing function keep passing this into other rx variables which might be other functions.

Well, go try it, it works. At least try out the features which exist before making a feature request!
