Thanks for your reply! I think I know `groovy` command and now I exactly suffer from `groovysh`. Let me try to speak it clearly. (on macOS) 1. I open a terminal. 2. Type "groovysh" and <CR> 3. A new window looks like a Java applet, named "Groovy Shell" launched, and the focus switch to it. 4. I switch the focus back to the terminal, and start to interact with REPL. What I am suffering is 3 and 4, each time I want to interact with REPL I have to switch the focus. Think about `jshell` or `python`, the REPL is of course a process, but not another window and even force switch the focus. Also photos in attach links, please pay attention to the focus is switched from 1 to 2. Best, tison.
