Minecraft like console in java

Question

So I am working on a http server app thing, and I need to make a inbuilt shell for some stuff (like minecraft). I tried a lot with jline but cannot get a proper prompt without the logs messing up the prompt input. Here's what I want:

• The prompt to disappear as the app logs something
• Then the prompt appears again
• But doesn't remove whatever I typed in the prompt

I am using log4j2 for the logging framework.

Answer 1

It should be feasible using JLine, however you'll need JLine and log4j2 to coexist peacefully. In order to do that, you'll have to implement a custom log4j appender that will write to the console using JLine's reader printAbove method.
