irb on Mac OS X not displaying previous lines

Tom Robinson

I just started using irb on my Mac. When I press the Up arrow I should
see the previously entered line, right? Instead it writes "^[[A" to the
prompt. I've tried Terminal.app, iTerm, and xterm within X11, all do the
same thing. Any ideas?

Thanks,

Tom

Works for me in Terminal.

Mac OS X 10.4.7
Ruby 1.8.4 via DarwinPorts (http://darwinports.opend...)

Ruby 1.8.4 from DarwinPorts depends on readline, so it's installed
for me. Recently, I found that the readline version from DarwinPorts
was updated. I installed it and broke Ruby stuff. I simply
deactivated the new one (5.1.x) and reactivated the old one (5.0.x).

Ok, I installed readline from Darwin Ports, but as you said its version
5.1. Is it possible to downgrade to an older version with Darwin Ports?

I tried building 5.0.5 from source
(http://cnswww.cns.cwru.edu/~chet/readline/...) but it failed.

You need not do anything but build your own ruby and move the stock
ruby aside (eg sudo mv /usr/bin/ruby /usr/bin/ruby182). OSX ships
with libedit and it works fine with no extra configuration options.

Yup, that did I. I installed from Darwin Ports.

Thanks.

It also works for me with ruby from Fink :)

Not quite the same, but I suppose it works too.
