        # WordMasterKMP

![kotlin-version](https://img.shields.io/badge/kotlin-1.8.0-orange)

Kotlin Multiplatform sample heavily inspired by [Wordle](https://www.powerlanguage.co.uk/wordle/) game and also [Word Master](https://github.com/octokatherine/word-master) and [wordle-solver](https://github.com/dlew/wordle-solver) samples.  The main game logic/state is included in shared KMP code with basic UI then in following clients

- iOS (SwiftUI)

- Android (Jetpack Compose)

- Desktop (Compose for Desktop)

### Shared KMP game logic/state

The shared `WordMasterService` class includes following `StateFlow`s representing the current set of guesses and updated status info for each letter.

```

val boardGuesses = MutableStateFlow>>(arrayListOf())

val boardStatus = MutableStateFlow>>(arrayListOf())

```

The various clients call `WordService.setGuess()` when a user enters a letter and then `WordService.checkGuess()` after row of letters

are entered...UI then reflects any resulting updates to above `StateFlow`'s.  The Compose clients for example do that using following (with any updates to those `StateFlow's` triggering recomposition)

```

val boardGuesses by wordMasterService.boardGuesses.collectAsState()

val boardStatus by wordMasterService.boardStatus.collectAsState()

```




On iOS we're using [KMP-NativeCoroutines](https://github.com/rickclephas/KMP-NativeCoroutines) library to map the `StateFlow`s to Swift `AsyncStream`s.  So, for example, our Swift view model includes

```

@Published public var boardStatus: [[LetterStatus]] = []

@Published public var boardGuesses: [[String]] = []

```

which are then updated using for example

```

let stream = asyncStream(for: wordMasterService.boardStatusNative)

for try await data in stream {

  self.boardStatus = data as! [[LetterStatus]]

}

let stream = asyncStream(for: wordMasterService.boardGuessesNative)

for try await data in stream {

    self.boardGuesses = data as! [[String]]

}

```

Any updates to `boardStatus` or `boardGuesses` will trigger our SwiftUI UI to be recomposed again.

### Remaining work includes

- check if overall word is valid and show indication in UI if not (ideally with animations!)

- better keyboard navigation

- share Compose code between Android and Desktop

- indicator in UI that correct guess entered (other than all letters being green)
