If some undergrad wants a fun one-week project to start the summer...
Write a replacement for "readline" that can be used by the Racket
command-line REPL.
Two reasons: (1) avoid license and not-working-out-of-the-box issues
with "readline"; (2) you can do cooler things, like auto-indent,
paren-matching, and up/down cursor that works in whatever portion of the
terminal the text occupies.
This can probably be layered atop
"http://www.neilvandyke.org/racket-charterm/";. If you find you need
some low-level feature not in that library, such as some additional
reporting of terminal characteristics or state, I could probably be
persuaded to add it.
Neil V.
