IRB is dying on me

Ruby
1

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

Sounds like your missing readline support.

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

Readline is the library that makes your irb behave more like a modern
shell. I added readline support to my Ruby when I compiled it.

–with-readline-dir=/usr/local

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.

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?

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