A very simple terminal interface library.

In 150 non-blank non-comment lines of Haskell (and 7 lines of C) vty provides:

Automatic handling of suspend/resume (SIGTSTP+SIGCONT)
Automatic handling of window resizes
Automatic computation of minimal differences
Minimizes repaint area, thus virtually eliminating the flicker problem that plagues ncurses programs
Automatically decodes keyboard keys into (key,[modifier]) tuples
Automatically supports refresh on Ctrl-L.
Automatically supports timeout after 50ms for lone ESC (a barely noticable delay)
Interface is designed for relatively easy compatible extension.

Current disadvantages:

No current support for non-ANSI terminals.
Minimal support for special keys on terminals other than the linux-console. (F1-5 and arrow keys should work, but anything shifted isn't likely to.)
Uses the TIOCGWINSZ ioctl to find the current window size, which appears to be limited to Linux and *BSD.

To compile the demonstration program: ghc --make Test.hs gwinsz.c
