Arrow Fx. Typed FP for the masses

Arrow Fx is a next-generation Typed FP Effects Library that makes effectful and polymorphic programming first class in Kotlin, and acts as an extension to the Kotlin native suspend system.

The library brings purity, referential transparency, and direct imperative syntax to typed FP in Kotlin, and is a fun and easy tool for creating Typed Pure Functional Programs.

Arrow Fx programs run unmodified in multiple supported frameworks and runtimes such as Arrow Effects IO, KotlinX Coroutines Deferred, Rx2 Observable, and many others.

Pure Functions, Side Effects, and Program Execution

Pure & Referentially Transparent Functions

A pure function is a function that consistently returns the same output when given the same input. Pure functions exhibit a deterministic behavior and cause no observable effects externally. We call this property referential transparency.

Referential transparency allows us to reason about the different pieces of our program in isolation.

To create a pure function in Kotlin, let’s use the keyword fun:


//sampleStart
fun helloWorld(): String =
  "Hello World"
//sampleEnd  
fun main() {
  println(helloWorld())
}

We can state that helloWorld is a pure and referentially transparent function because invoking helloWorld() consistently returns the same output given the same input, and does not produce observable changes in the external world.

Side effects

A side effect is an externally observable effect a function performs in addition to returning a value.

Performing network or file IO, writing to streams, and, in general, all functions that return Unit are very likely to produce side effects. That’s because a Unit return value denotes no useful return, which implies that the function does nothing but perform effects.

In Arrow Fx, we use suspend fun to denote a function that may cause side effects when invoked.

In the example below, println(a : Any): Unit is a side effect because, every time it’s invoked, it causes observable effects by interacting with the System.out stream and signals that it produces no useful output by returning Unit.

When we denote side effects as suspend, the Kotlin compiler will ensure that we’re not applying uncontrolled side effects in the pure environment.


//sampleStart
fun helloWorld(): String =
  "Hello World"

suspend fun sayHello(): Unit =
  println(helloWorld())

sayHello()
//sampleEnd  
javax.script.ScriptException: error: suspend function 'sayHello' should be called only from a coroutine or another suspend function
sayHello()

Compiling the snippet above will result in a compilation error.

The Kotlin compiler disallows the invocation of suspended functions in the pure environment because suspend fun requires declaration inside another suspended function or a continuation.

A continuation is a Kotlin Interface, Continuation<A>, that proves we know how to handle success and error cases resulting from running the suspended effect.

This is a great built-in feature of the Kotlin compiler that already makes it an ideal choice for Typed FP, but it’s not the only one.

Continue reading on if you’re curious to see how the Kotlin Compiler and Arrow Fx can eliminate many of the functional idioms by using direct syntax, overall effectful monads.

suspend composition

Applying and composing suspended side effects is allowed in the presence of other suspended side effects.

In the example below, sayHello and sayGoodBye are valid inside greet because they are all suspended functions.

suspend fun sayGoodBye(): Unit =
  println("Good bye World!")

suspend fun sayHello(): Unit =
  println("Hello World")

suspend fun greet(): Unit {
  sayHello() // this is ok because
  sayGoodBye() // `greet` is also `suspend`
}

fx composition

Side effects can be composed and turned into pure values in fx blocks.

Turning side effects into pure values with effect

effect wraps the effect and turns it into a pure value by lifting any suspend () -> A user-declared side effect into an IO<A> value.


import arrow.fx.IO
import arrow.fx.extensions.fx
//sampleStart
suspend fun sayHello(): Unit =
  println("Hello World")

suspend fun sayGoodBye(): Unit =
  println("Good bye World!")

fun greet(): IO<Unit> =
  IO.fx {
    val pureHello = effect { sayHello() }
    val pureGoodBye = effect { sayGoodBye() }
  }
//sampleEnd
fun main() {
  println(greet())
}

When we capture suspended side effects as IO values with effect, we can pass them around and compose them until we are ready to apply the effects. At this point, nothing has happened because greet and effect are lazy values.

Applying side effects with !effect

We apply side effects with the operator !. Once you purify a side effect with effect, you can extract its value in a non-blocking way. !effect takes the suspended side effects sayHello() and sayGoodbye() and ensures the continuation context controls them before they get a chance to be executed. This ensures our effect compositions are pure and referentially transparent, and will only run at the edge.

Note that running greet() in the previous example does not perform any effects because it returns a wrapped lazy value. Since invoking this function does not produce effects, we can be confident that greet is pure and referentially transparent, despite referring to the effects application.


import arrow.fx.IO
import arrow.fx.extensions.fx
//sampleStart
suspend fun sayHello(): Unit =
  println("Hello World")

suspend fun sayGoodBye(): Unit =
  println("Good bye World!")

fun greet(): IO<Unit> =
  IO.fx {
    !effect { sayHello() }
    !effect { sayGoodBye() }
  }
//sampleEnd
fun main() {
  println(greet()) //greet is a pure IO program
}

An attempt to run a side effect in an fx block not delimited by effect or !effect also results in a compilation error.


import arrow.fx.IO
import arrow.fx.extensions.fx
//sampleStart
suspend fun sayHello(): Unit =
  println("Hello World")

suspend fun sayGoodBye(): Unit =
  println("Good bye World!")

fun greet(): IO<Unit> =
  IO.fx {
    sayHello()
    sayGoodBye()
  }
//sampleEnd
javax.script.ScriptException: error: restricted suspending functions can only invoke member or extension suspending functions on their restricted coroutine scope
    sayHello()
    ^

Arrow enforces usage to be explicit about effects application.

Applying existing datatypes

Composition using regular datatypes such as IO is still possible within fx blocks just like effect blocks. In addition to !, you can also use the extension function bind() to execute them.


import arrow.fx.IO
import arrow.fx.extensions.fx
//sampleStart
fun sayInIO(s: String): IO<Unit> =
  IO { println(s) }

fun greet(): IO<Unit> =
  IO.fx {
    sayInIO("Hello World").bind()
  }
//sampleEnd
fun main() {
  println(greet()) //greet is a pure IO program
}

Executing effectful programs

The greet program is ready to run as soon as the user is ready to commit to an execution strategy that is either blocking or non-blocking. blocking execution strategies will block the current thread that’s waiting for the program to yield a value, whereas non-blocking strategies will immediately return and perform the program’s work without blocking the current thread.

Since both blocking and non-blocking execution scenarios perform side effects, we consider running effects as an unsafe operation.

Arrow restricts the ability to run programs to extensions of the UnsafeRun type class.

Usage of unsafe is reserved for the end of the world and may be the only impure execution of a well-typed functional program.


import arrow.fx.IO
import arrow.unsafe
import arrow.fx.extensions.io.unsafeRun.runBlocking
import arrow.fx.extensions.fx
//sampleStart
suspend fun sayHello(): Unit =
  println("Hello World")

suspend fun sayGoodBye(): Unit =
  println("Good bye World!")

Arrow Fx emphasizes the guarantee that users understand when they are performing side effects in their program declaration.

Arrow Fx programs are not restricted to IO but, in fact, are polymorphic and would work unmodified in many useful runtimes like the ones we find in popular libraries such as KotlinX Coroutines Deferred, Rx2 Observable, Reactor framework Flux, and, in general, any third party data type that can model sync and async effect suspension. See Issue 1281, which tracks support for those frameworks, or reach out to us if you are interested in support for any other framework.

If you’re not very familiar with Functional Programming, and you’ve made it this far, you may realize that, despite the buzzwords and some FP jargon, you already know how to use Arrow Fx in general. This is because Arrow Fx brings the most popular imperative style to effectful programs with few simple primitives for effect control and asynchronous programming.

Conclusion

Complementing the Kotlin Coroutines library, Arrow Fx adds an extra layer of safety to concurrent and asynchronous programming so you’re well aware of where effects are localized in your apps. It does this by empowering polymorphic programs that can be interpreted untouched, preserving the same declaration in multiple popular frameworks such as Rx2, Reactor, etc.

Arrow Fx offers direct style syntax and effect control without compromises, and removes the syntactic burden of type parametrization while still yielding programs that are pure, safe, and referentially transparent.

Despite some limitations of the Kotlin type system, like lack of Higher Kinded Types, the Kotlin language is excellent for encoding typed programs with a first-class imperative syntax for FP. These programs are approachable by the broader programming community, and arguably easier to encode than some solutions currently used in mainstream Kotlin and Scala FP communities.
