[polyml] fancy tty tricks (with curses?)

[M***@data61.csiro.au]

Has anyone used the FFI interface or similar to link libcurses or similar? I could try to talk ANSI terminal sequences directly, but querying terminal state with these seems pretty painful. (At the very least one has to put standard input into a non-blocking state, and I found the Basis documentation on how I might do this very confusing.) And then one is breaking the very abstraction that curses is trying to provide...

As a bare minimum for example, I'd like to get the width of the current terminal.

I once did something similar, but not through FFI. I directly used the
terminfo database instead (also used by curses, man terminfo for details).
I guess this what you mean by ANSI terminal sequences.
But I was using only basic capabilities like moving the cursor, beeping,
or deleting characters or lines, switching to reverse video, etc.
