Description

I am building webtau REPL based on groovysh.

Right now I am looking for ways to handle ctrl+c to stop currently running command instead of closing the whole REPL process.

After some googling I found that Jline has `handleUserInterrupt` property. I am not sure if that will fully solve my problem.
I can't find a way to pass the prop during groovsh instance creation. 

 

groovysh.runner.reader.handleUserInterrupt = true

 

Is throwing null pointer as the `runner` instance gets created only after `run`. And `run` takes control and you can't set anything after it. 

Would it be possible to add an option to pass handleUserInterrupt? 

If you are aware of other ways to handle ctrl+c - that would be super helpful 

Thank you.
