So, what do people use to build text based menu systems, and to do other
terminal based maneuvers in lisp? In C I would reach for curses, but
what now? Any hints?

Use CFFI to call Ncurses _or_ PDcurses (to cover non-Linux systems). A
reasonably useful implementation can be found here:

http://common-lisp.net/project/lifp/sewers-src.zip

(check out curses.lisp; it also contains some bloat such as REPL
implementation; oh, there is also a whole game that uses the library)

Ouch! I sense a lack, or maybe I'm into unidiomatic territory.


I don't see how Lisp is different from C in this case. In either case you have
to call some external library. The fact that curses implementations are written
in C doesn't matter. This is extremely low-level OS-specific stuff, and perhaps
C is the best language to implement that stuff in. Once you have FFI bindings,
curses is just as easy and natural to use in Lisp as in C.
