Memoization

Memoization is a Swift compiler plugin that provides a @memoized macro for automatically memoizing function results. By leveraging Swift's powerful macro system, @memoized simplifies caching function outputs, improving performance by avoiding redundant computations for repeated inputs.

Features

• Automatic Caching: Automatically caches function results based on input parameters.
• Thread-Safe Storage: Utilizes a thread-safe storage mechanism to handle concurrent access.
• Easy Integration: Seamlessly integrates with your Swift projects using Swift's macro system.
• Reset Capability: Provides functions to reset the cache for specific memoized functions.

Just a heads-up, while this implementation gets the job done with current Swift macros, Swift 5.10+ brings in preamble macros (SE-0402). These could offer different ways to handle the setup part of the macro down the road, potentially making things a bit neater.

Installation

To integrate MemoizationMacros into your Swift project, follow these steps:

1. Add the Package

   Add Memoization to your project's dependencies in your Package.swift:

   dependencies: [
       .package(url: "https://github.com/brunogama/Memoization.git", from: "0.0.1"), // Adjust version as needed
   ],

2. Import the Module

   import Memoization

Usage

Annotate your functions with the @memoized macro to enable memoization.

import Memoization

class Calculator {
    @memoized
    func fibonacci(_ n: Int) -> Int {
        if n <= 1 { return n }
        return fibonacci(n - 1) + fibonacci(n - 2)
    }
    
    // Macro will add a function withe allmost same signitigure but it will starts with prefix memoized. 
}
