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.

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.
