libpython-clj VS ArcadiaGodot

It’s also worth noting that Clojure has libpython-clj (https://github.com/clj-python/libpython-clj) which offers an interface with Python from another lisp. Here are some advanced ML and dataviz examples using that lib: https://github.com/gigasquid/libpython-clj-examples.

Basically, you take a programming language and make it work on a platform that meant to be programmed using a different PL. Clojure is hosted by design - it's not Java, but can be used to program for JVM. It ain't Javascript, but can be used to target nodejs and browser; not an [official] CLR language, but you can write .Net programs. You can use Clojure to make Flutter apps with ClojureDart. You can integrate Python into Clojure with libpython-clj. Or write Clojure to target Erlang/OTP; or Rust; or R; There's even a clojure-like language for Lua - Fennel.

There's something about Clojure people like so much, they want it to work atop any platform.

There's this project that's used a lot for taking advantage of Pythons ecosystem through Clojure JVM. https://github.com/clj-python/libpython-clj

Ahh, makes sense. Well, if you ever wanna steal some of python's thunder, libpython-clj worked great for me lol. Supposedly py4cl fills a similar role in Common Lisp.

High quality interop with any python library via libpython-clj including, but not limited to, keras, numpy, matplotlib, and pandas. This includes zero copy paths from many of those.

libpython-clj now has Java bindings...go tell all your Java friends!

To follow on what I was saying before about editor integration with REPLs, you can actually take it even farther than those simple examples. Clojure, for example, provides the ability to start a network-based REPL (nREPL) inside a running application. You can connect to it and view, change, or add to the program's state in real time while building your application. Combine that with the ability to send code from your editor into a REPL that I mentioned, and you get stuff like this where you can evaluate Clojure code on-the-fly in Unity. (Also possible with Godot.)

Nice work. Out of curiosity, though, why did you go that route instead of the Arcadia Godot port? Was there something missing or wrong with that, or did you just want to see if you could get JVM Clojure working specifically?

For what it's worth, Godot can do the same: there's a Godot version of Arcadia for using Clojure, and Godot F# tools takes some of the tedium out of using F#, though you have to make a small tweak to the .fsproj file it generates because the Mono assemblies moved. It works via a cheesy little hack: you make a C# script in Godot that's just an empty class that does nothing else but inherit from an F# class, and the F# project builds at the same time by adding it as a dependency of the Godot-generated .csproj file. Godot doesn't know anything weird is going on and it just kind of works :)

Arcadia uses ClojureCLR to work with Clojure in unity. Also Godot engine version.
