An option to send prompts to stderr (or the platform equivalent) about clikt HOT 3 CLOSED

If I understand you correctly, it sounds like you want to throw away most Clikt output, but still have interactive prompt.

I don't think that makes sense semantically, but Clikt is a pragmatic library, so if it's useful in practice, I would consider adding it.

Unfortunatley, it's not possible to implement you use case. The only mechanism the JVM provides for detecting whether you have an interactive console is to check if System.console() is null, and it is null if any stream is redirected. So if you pipe stdout or stdin somewhere, the JVM acts like stderr is also redirected. So you wouldn't be able to interact with it anyway.

Interesting, I didn't know that. I suppose it might be a portability tradeoff.

I did some looking around to see how other programs would prompt for passwords. Seems like programs like SSH access the TTY directly instead, bypassing any redirection. But I suppose that would be well out of the scope of Clikt.

But thanks for hearing me out, I learned something today. And of course, thanks for the library!

Not a problem, that you for the suggestion.
