Declarative Programming Language
|wand created to support all platfroms
Prototype implemented on Swift
Location.one | MotionEvent.one | .all {
}Wand started from the idea about receiving anything in most efficient way.
Add one sign to anything and retreive the result ๐ฆ
Imagine that you have the black box that can give you an Any object.
You don't know what's already in the box and what happens inside.
Ask for an object that you need with a microservice:
|{ (result: Object) in
}ingredients | { (result: Object) in
}ingredients | .one { (t: T) in
} | .every { (u: U) in
} | .while { (v: V) in
true

ex API
//Request location updates
|{ (location: CLLocation) in
}//Request .authorizedAlways permissions and only one location object
CLAuthorizationStatus.authorizedAlways | { (status: CLAuthorizationStatus) in
} | .one { (location: CLLocation) in
}๐ฆ An ideal API acts as the black box
โก๏ธ Is it possible to incapsulate whole data receiving process and memory managment duty to one symbol?

In Unix-like computer operating systems, a pipeline is a mechanism for inter-process communication using message passing. A pipeline is a set of processes chained together by their standard streams, so that the output text of each process (stdout) is passed directly as input (stdin) to the next one. The second process is started as the first process is still executing, and they are executed concurrently.

//Request .authorizedWhenInUse permissions
CLAuthorizationStatus.authorizedWhenInUse | { (status: CLAuthorizationStatus) in
}//Request location updates
//Uses .startUpdatingLocation()
|{ (location: CLLocation) in
}//Request .authorizedAlways permissions and only one location object
//Uses .requestLocation() for efficient power consumption
CLAuthorizationStatus.authorizedAlways | { (status: CLAuthorizationStatus) in
} | .one { (location: CLLocation) in
}//Request pedometer data updates
|{ (data: CMPedometerData) in
}//Scan for a bluetooth peripherals
|{ (peripheral: CBPeripheral) in
}//Wait for a Notification
UIWindow.keyboardWillShowNotification | { (n: Notification) in
}//Enumerate contacts
CNContact.predicateForContacts(matchingName: "John") | .every { (contact: CNContact) in
}//Scan a tag
|.every { (tag: NFCNDEFTag) in
}//Perform face observation
URL(string: "http://example.com/image.jpg") | { (faces: [VNFaceObservation]) in
}//Perform pose observation
//Wait for two persons
data | .while { (bodies: [VNHumanBodyPoseObservation]) in
bodies < 2
}//Detect shakes
|{ (motion: UIEvent.EventSubtype) in
if motion == .motionShake {
}
}//Customization
let wand = |{ (hands: [VNHumanHandPoseObservation]) in
}
let request: VNDetectHumanHandPoseRequest = wand.obtain()
request.maximumHandCount = 4
let preview: AVCaptureVideoPreviewLayer = wand.obtain()
view.layer.addSublayer(preview!)//Attach Ask<Error> to the scope
any | { (error: Error) in
}//Or use the result handler
//Nil error means successed result
any | { (error: Error?) in
}A long time ago in a galaxy far, far away....
There was proper Jump to Definition ability in Xcode
For predefined operators so as custom too:
