I have released the ZeptoN transcompiler on my GitHub repo at https://github.com/wgilreath/ZeptoN.
This is version 1.0.1 as a few glitches were fixed. The transcompiler compiles into Java source code, and then uses the backend Java Compiler API to produce a Java .class file that can execute on JDK 11 and greater. A pre-built JAR file is ready to run. The entire software collection and some ZeptoN “zep” source code files are released under GPL v. 3.0.
I’m currently working on a short whitepaper, which I will publish and release sometime soon. ZeptoN is Java syntax but without object-oriented overhead. I was tinkering with multi-threading, but simpler.
I’d love to have contributors to the project!
