ANTLR Kotlin fork

[Fancryer]

Hello, I use ANTLR almost all the time when developing in Java/Kotlin, but I am a little frustrated that it is implemented exclusively in Java and uses quite a lot of deprecated methods and classes, as well as unsafe solutions. Can I fork it in Kotlin? I plan to implement null safety wherever possible, as well as keep the code cleaner and more functional. Yes, I understand that this is a big project, but the experience would be quite useful, I think. If necessary, I may limit its use to personal use.

Hi there,
you might want to explore the existing Kotlin implementation, see https://github.com/Strumenta/antlr-kotlin

Also, we work on ANTLR5 that rely on Kotlin as well.

A bit too Gradle-heavy. I'd like to see a simple antlr4 -Dlanguage=Kotlin -no-listener -visitor mygrammar.g4 from the command line succeed, and for that I hit the python/classpath barrier. How do I call antlr as java when the recommendation is to pip install it??? The python proxy file shows no hint on how to pass additional java arguments...
