IRB is dying on me

Peter Bailey

9/24/2007 4:28:00 PM

Why is it that I can't repeat lines and edit them in IRB? If I press my
cursor up key, normally, that repeats the line I just entered. Then, I
can backspace and modify any part of that line I want before executing
it. But, it's dying on me. After I backspace a few characters, the
cursor goes nuts, and, I've lost my instruction string. Has anyone else
seen this behavior?

Thanks,
Peter

Sorry, but, I don't know what that is. Is that a gem I need to install?

OK. Well, I'm on Windows and I didn't compile anything. Ruby's been
"out-of-the-box" for me for almost a year now and it's worked
beautifully. I'll look into it further. Thanks.

Well, I tried everything including uninstalling and re-installing Ruby.
But, it still isn't working. This is very weird.

Ask yourself if you've installed anything recently (since you last
remember it working) ...
Something could've clobbered something.
Is your keyboard working in every app?
Is it CygWin or something?
