plzoo VS simplelanguage

Andrej Bauer's plzoo?

Such as OCaml. Incidentally, the first versions of Rust itself were written in OCaml. You can also find a ton of examples in this domain.

That sort of stuff is easy to do with Truffle (which, ironically, lets you define a language using what they call the "truffle dsl").

The SimpleLanguage tutorial language has a bigint style number scheme with efficient optimization:

Truffle has no opinion on how you parse the sources. It cares about how you execute them from an intermediate Truffle guided representation produced by the parser.

In other words antlr and truffle are a great fit. We even use this pairing for our example language simplelanguage.

Do you have any feedback on how we could improve the docs? If so, please let us know!

I believe the easiest way to start a new Truffle language implementation is to fork SimpleLanguage [1] and turn it into your language. Did you try to do that?

Finally, I would suggest you to take a look at the Truffle/GraalVM ecosystem(https://www.graalvm.org/graalvm-as-a-platform/language-implementation-framework/). The documentation is not exactly very elaborate, but a few good resources are Mumbler(http://cesquivias.github.io/blog/2014/10/13/writing-a-language-in-truffle-part-1-a-simple-slow-interpreter/#mumbler-language), SimpleLanguage(https://github.com/graalvm/simplelanguage), and (https://www.endoflineblog.com/graal-truffle-tutorial-part-4-parsing-and-the-trufflelanguage-class).
