classificator VS kotter

You can check out my project https://github.com/varabyte/kotter if you want to see something that makes heavy use of extension functions (even though if you're a beginner using it, you probably wouldn't notice, because Intellij IDEA is so good about auto-importing things for you).

Actually, more often than not I was talking about this library: https://github.com/varabyte/kotter. With a smattering of https://github.com/varabyte/truthish.

I'm currently using Picnic and Mordant which are working nicely. I've tried out Kotter and Text-IO, but they either open a Swing terminal or require you to run a `.bat` script or something.

I'm not too sure how to answer your question about language features in Kotter. Except maybe to point you at its extensive README and large collection of examples.

The first few examples I wrote were fairly bland, basically shaping and testing features as I created them. text, anim, blink, and input are in that category. (Plus, Kotter didn't have unit tests in the early days; instead, I just ran those programs over and over and over again).

https://github.com/varabyte/kotter - A library for writing dynamic console applications.

You can find the project for the code here. As it's just an example project and not some final production codebase, so there's only a single source file in it, main.kt. It clocks in at 462 lines of code to accomplish everything you see above, and it took about a day.

Hey OP, maybe it's overkill for you to change the implementation at this point but I wrote https://github.com/varabyte/kotter which is a Kotlin terminal library that runs your app in a virtual terminal if it can't run otherwise (e.g. in the intellij terminal). You'd probably be able to use it as a backend for inquirer if you were interested.

Gotcha! I created https://github.com/varabyte/konsole/issues/63 based on this conversation. Feel free to review it and add anything I may not have captured.
