luaj VS jbang

I've found a few options for libraries that make this possible, notably LuaJava, LuaJ, JLua, and jLuaScript, but I'm having a tough time setting them up and getting them to work.

I assume you are referring to this? http://www.luaj.org/luaj/3.0/README.html#1

I'm getting an exception that the lua interpreter cannot find the "helper" module, and I'm not sure why. I'm reading the ReadMe on their GitHub page about require, https://github.com/luaj/luaj, in the Libraries of Java Functions section, and there isn't anything about calling other lua files. Do I need to load each of them with globals.loadfile? I'm not exactly sure where this is going wrong, I'd assume the interpreter would understand the require keyword and look for a helper.lua file.

I did see that there is a JSR-223 implementation of Lua at https://github.com/luaj/luaj, and contemplated using that for dissection if nothing else, but then realised that the bulk of Wireshark/tshark's dissectors are still in C, and didn't want to go down the JNA/JNI route.

This might be what you're after https://github.com/luaj/luaj

Its library made by maven folks that allows easy embedding of the resolver. Im about to move it it in jbang https://github.com/jbangdev/jbang/pull/1604

Congratulations. I believe there is room for a micro framework that is smaller than Javalin or SparkJava.

That said, if you want to cash even more on minimalism, you may want to provide a single-file example using JBang[0].

These would be awesome changes and fully in the spirit of what we managed to do already in jbang (https://jbang.dev). Having the verbosity removed would make it even better.

big part of why I made jbang.dev so if you want to quickly play with all the suggested technologies in this thread without being a java build tool master do give it a go.

(jbang being https://jbang.dev)

Quarkus provides the option to create command line apps, and this is so kool, since you can also compile these into native. We are just going to make simple app for demo purpose in this blog. But if you are looking into creating some serious nirvana of cli apps take a look at this guide at quarkus.io using picocli or JBang

https://jbang.dev provides a bunch of ways to build and distribute simple java apps.
