# DuctTape
📦 KeyPath dynamicMemberLookup based syntax sugar for Swift.
```swift
let label: UILabel = UILabel().ductTape
.numberOfLines(0)
.textColor(.red)
.text("Hello, World!!")
```
Above is same as below definition.
```swift
let label: UILabel = {
let label = UILabel()
label.numberOfLines = 0
label.textColor = .red
label.text = "Hello, World!!"
return label
}()
```
## Usage
NSObject already has been compatible with DuctTape, so you can access `.ductTape` property like below.
```swift
let builder: Builder = UIView().ductTape
```
If you access `.ductTape`, it returns `Builder` that provides setter of properties via KeyPath dynamicMemberLookup.
```swift
let view: UIView = UIView().ductTape
.backgroundColor(.red)
.translatesAutoresizingMaskIntoConstraints(false)
```
#### How to access methods
If you want to access methods of object which is building, `func reinforce(_ handler: (Base) -> Void) Builder` enable to access methods.
```swift
let collectionView: UICollectionView = UICollectionView().ductTape
.backgroundColor(.red)
.reinforce { collectionView in
collectionView.register(UITableViewCell.self, forCellWithReuseIdentifier: "Cell")
}
```
`Builder` has `func reinforce(_ t1: T1, ..., handler: (Base) -> Void) Builder` methods.
In additional usage, be able to access outside object with `func reinforce` if passing objects as arguments.
```swift
lazy var collectionView: UICollectionView = UICollectionView().ductTape
.translatesAutoresizingMaskIntoConstraints(false)
.reinforce(view) { collectionView, view in
view.addSubview(collectionView)
NSLayoutConstraint.activate([
view.topAnchor.constraint(equalTo: collectionView.topAnchor),
view.leadingAnchor.constraint(equalTo: collectionView.leadingAnchor),
view.trailingAnchor.constraint(equalTo: collectionView.trailingAnchor),
view.bottomAnchor.constraint(equalTo: collectionView.bottomAnchor)
])
}
```
#### How to use DuctTape with self-implemented classes
There are two ways to use DuctTape.
1. Use DuctTapeCompatible
```swift
class Dog: DuctTapeCompatible {
var name: String
}
let dog: Dog = Dog().ductTape
.name("Copernicus")
```
2. Use Builder directly
```swift
class Dog {
var name: String
}
let dog: Dog = Builder(Dog())
.name("Copernicus")
```
#### Sample Code
```swift
class ViewController: UIViewController {
let flowLayout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
.ductTape
.minimumLineSpacing(10)
.minimumInteritemSpacing(10)
.itemSize(CGSize(width: 100, height: 100))
.scrollDirection(.vertical)
lazy var collectionView: UICollectionView = UICollectionView(frame: .zero,
collectionViewLayout: flowLayout)
.ductTape
.dataSource(self)
.delegate(self)
.translatesAutoresizingMaskIntoConstraints(false)
.reinforce {
$0.register(UICollectionViewCell.self, forCellWithReuseIdentifier: "Cell")
}
override func viewDidLoad() {
super.viewDidLoad()
view.addSubview(collectionView)
NSLayoutConstraint.activate([
view.topAnchor.constraint(equalTo: collectionView.topAnchor),
view.leadingAnchor.constraint(equalTo: collectionView.leadingAnchor),
view.trailingAnchor.constraint(equalTo: collectionView.trailingAnchor),
view.bottomAnchor.constraint(equalTo: collectionView.bottomAnchor)
])
}
}
```
