The Q programming language has an associated shell. How does one access his last input in the shell? For example, if I type:
q) a:45
in the next prompt q), I would like to recover a:45 by hitting the up arrow (as in bash), however, this does not work in the Q console. What does work?
On Linux or OS X you should use rlwrap. It is included in most Linux package repositories. On OS X I installed rlwrap via MacPorts, which requires Xcode to be installed.
On Windows the q console comes with this functionality and you don't need to install anything.
