Command line / IRB won't return values - Ruby
When I use irb in the command line for ruby, sometimes it won't return any values. This seems to be happening after I've made a typo or entered incorrect code.
How do I exit this mode and go back to using irb normally? It won't let me quit with the 'quit' command, and I have to shut down the command line / Terminal and go back into it.
When this happens in vim you can press esc ! q n enter in sequence and it brings you back into the editor.
I've attached a screen shot showing what happens - as you can see it won't return any value for i in this instance.
Thanks
This occurs when you have entered an incomplete expression that requires closing characters of some kind to complete it. Example:
The ? in the prompt indicates that the REPL is waiting on closing characters to evaluate the expression.
You can exit this state by completing the expression or by aborting its evaluation with Ctrl+c.
