Arrow up and down does not work any more in Perl debugger and CPAN client

I used to use Active Perl on my Mac OS X (v 10.7.5) and then I switched to the one provided via mac ports (v 5.12.4).

Now when I run the CPAN client or the perl debugger, I cannot access the history using ArrowUp and ArrowDown, what is shown at the prompt is ^[[A and ^[[B respectively.

At least on the debugger the history works, I can access past commands via !num.

Solution

  • By default the only Term::ReadLine handler you get is Term::ReadLine::Perl which is quite simple and doesn't understand things like arrow keys. You probably want to install Term::ReadLine::Gnu.
