What does HackerNews think of mosaic?
An experimental tool for building console UI in Kotlin using the Jetpack Compose compiler/runtime
Language:
Kotlin
A similar project is Mosaic.
It's exactly the same concept, but for Jetpack Compose, the primary toolkit used in modern Android apps.
You can use it in desktop JVM apps written in Kotlin.
There's also Mosaic, which is an experiment of sorts to build console UI using Kotlin and Jetpack Compose: https://github.com/JakeWharton/mosaic
Jetpack Compose (Google's alternative on Android, that also works pretty much anywhere you can run a JVM and others like the web [1], terminals[2], powerpoints[3], iOS[4] if you squint, as well as pretty much anywhere you have an imperative API that you want to transform into a functional model[5]) is three years old and is infinitely more polished and has better tools than anything Apple has put out in all of SwiftUI's existence. Apple is bringing this upon themselves with their "major updates" concept for SwiftUI coming every other year, where components aren't even available on old versions of iOS. A UI toolkit is a library like any other, version it like a library and match patch releases.
