# ReactiveTask

ReactiveTask is a Swift framework for launching shell tasks (processes), built using [ReactiveSwift](https://github.com/ReactiveCocoa/ReactiveSwift).

```swift

let strings = [ "foo\n", "bar\n", "buzz\n", "fuzz\n" ]

let input = SignalProducer(values: strings.map { $0.data(using: .utf8)! })

let task = Task("/usr/bin/sort")

// Run the task, ignoring the output, and do something with the final result.

let result: Result? = task.launch(standardInput: input)

    .ignoreTaskData()

    .map { String(data: $0, encoding: .utf8) }

    .ignoreNil()

    .single()

print("Output of `\(task)`: \(result?.value ?? "")")

// Start the task and print all the events, which includes all the output

// that was received.

task.launch(standardInput: input)

    .flatMapTaskEvents(.concat) { data in

        return SignalProducer(value: String(data: data, encoding: .utf8))

    }

    .startWithNext { (event: TaskEvent) in

        switch event {

        case let .launch(task):

            print("launched task: \(task)")

        case let .standardError(data):

            print("stderr: \(data)")

        case let .standardOutput(data):

            print("stdout: \(data)")

        case let .success(string):

            print("value: \(string ?? "")")

        }

    }

```
