I’m trying to create a library of functions for programs that use a
command line interface. One feature I’d like to implement is a
date_selector. What I’d like to have is the $stdout display todays date
with one field somehow highlighted. The user could then navigate and
adjust using the arrow keys untill the desired date is set and press
Enter. My problem is that I’m not sure how to rewrite something that’s
already been printed to the standard output, if that’s possible at all.
Does any of this make sense or am I crazy?
