I’m writing a tool that is executed as a shell in Perl. I want it to have a history, so that if you press the up arrow, you go back to the previous command, just like bash or other shells. How should I go about this?
— EDIT —
Thanks to daxim for pointing me towards Term::ReadLine::Gnu. I was able to get it to work on my Linux box and it’s exactly what I was looking for. However, my main dev machine is running OS X. When I try to install the module, I get this error:
~/Downloads/Term-ReadLine-Gnu-1.19 > perl Makefile.PL
Found `/usr/lib/libtermcap.dylib'.
gcc-4.2 -arch i386 -arch ppc -g -pipe -fno-common -DPERL_DARWIN -fno-strict-aliasing -I/usr/local/include - DHAVE_STRING_H rlver.c -o rlver -arch i386 -arch ppc -L/usr/local/lib -lreadline -ltermcap

The libreadline you are using is the libedit library. Use the GNU Readline Library.

I am currently making my way through the Google results for this problem, but if anyone has seen this before and has pointers, that would be much appreciated. Thanks!
Term::ReadLine::Gnu is the best module for this, Term::ReadLine::Perl the fallback.
