Questions tagged [ncurses]

The ncurses package is a subroutine library for terminal-independent screen-painting and input-event handling.

The Ncurses (new curses) library is a free software emulation of curses portable to most terminal systems. It uses Terminfo format, supports pads, color, multiple highlights, forms, characters and function-key mapping, and has all the other SYSV-curses enhancements over BSD Curses.
