DecoratableMacro 🎨

Automatically generate decorator classes for Swift protocols using macros. Just add @Decoratable to your protocol — the macro will create a ready-to-use decorator class!

Features ✨

• 🚀 Auto-generated decorators for Swift protocols
• 🔒 Full access control support (public, internal, fileprivate, private)
• 📦 2-minute integration via Swift Package Manager

Installation 📦

1. Add the package to your Package.swift:

dependencies: [
    .package(
        url: "https://github.com/Kristalev/DecoratableMacro.git", 
        from: "1.0.0"
    )
]

2. Add to your target:

.target(
    name: "YourTarget",
    dependencies: [
        .product(name: "DecoratableMacro", package: "DecoratableMacro")
    ]
)

Usage 🛠️

1. Annotate your protocol with @Decoratable:

import DecoratableMacro

@Decoratable
protocol Router {
    func push(viewController: UIViewController) 
}

2. The macro generates:

class RouterDecorator: Router {
    private var decoree: any Router
    
    init(_ decoree: any Router) {
        self.decoree = decoree
    }
    
    func push(viewController: UIViewController) {
        decoree.push(viewController: viewController)
    }
}

Limitations ⚠️

1. Works only with protocols (not classes/structs)
2. Doesn't support generic protocols
3. Not supported method modifier compatibility (async/throws)
