I've created a Kotlin version of MiniScript, porting it from the C# original, which means it can now run on the JVM as well 🙂. I hope this is useful for somebody at some point, but even if it's not, it was a fun exercise to try.
The project is also a "multiplatform" Kotlin one, so in theory it could also be compiled directly to JS and natively, however there are a few "stubs" to fill before this works, so this hasn't been tested yet.
Code and a few words about it are here: https://github.com/Arcnor/miniscript-kt
Let me know what you think!
