picocli
Picocli is a modern framework for building powerful, user-friendly, GraalVM-enabled command line apps with ease. It supports colors, autocompletion, subcommands, and more. In 1 source file so apps can include as source & avoid adding a dependency. Written in Java, usable from Groovy, Kotlin, Scala, etc. (by remkop)

GraalVM for JDK 21 is here
Picocli allows using a compiler annotation processor to generate classes at compile time instead [0].

Any library you would like to recommend to others as it helps you a lot? For me, mapstruct is one of them. Hopefully I would hear some other nice libraries I never try.
Picocli is a pretty good one for writing CLI apps

Java 20 / JDK 20: General Availability
The command line example gave me the "ick". It is usually preferrable to parse the command line arguments into one instance of a custom "command class", rather than into a list of things. Like jcommander, picocli or jbock do.
-
any opinion good or bed about a code that smells?
Complex argument parsing needs to be auto-generated by libraries like picocli. Even if you need something custom, it'd be quicker to write an Annotation processor from scratch than editing that file.

Owl: A toolkit for writing command-line user interfaces in Elixir
https://github.com/remkop/picocli
"Picocli-based applications can be ahead-of-time compiled to a GraalVM native image, with extremely fast startup time and lower memory requirements, which can be distributed as a single executable file."

Building a Java CLI. How can I make it more powershell-friendly
Using picocli to handle your command line options gives you the best chance to automatically generate an ArgumentCompleter script in the future, but won't help you today (other than possibly making your command line handling more standardized & easier).

Kotlin CLI apps development status
If you wanted to give writing a CLI a go yourself from scratch, I recommend searching for Java solutions first. Kotter itself is built on top of https://github.com/jline/jline3

Kotter (a Kotlin-idiomatic library for writing dynamic console application) hits 1.0!
I sit on top of JLine at the very bottom.

I've created a small library for interactive CLI UI called 'kotlin-inquirer'
Unfortunately, It doesn't work with Intellij terminalsee this issue

Introducing incomplete: A Simple Clojure Code Completion Library
Right now REPLy is kind of stuck and it needs to be updated to the latest version of JLine eventually (https://github.com/jline/jline3).

How do I get 'function key inputs' from System.in ? it stores as a String, but F1 = "P" ?? and appears as "^[OP", what data type are function keys ? thanks!
thanks for the reply, we;ve found the jlines library https://github.com/jline/jline3. it has key bindings for key events and a non blocking line reader, but now im stuck on changing it to blocking to read lines in ! for data entry ! thank you again.
