The ncurses package

[ Tags: foreign, gpl, library, user-interfaces ] [ Propose Tags ]

GNU ncurses is a library for creating command-line application with pseudo-graphical interfaces. This package is a nice, modern binding to GNU ncurses.

The following example is a program that displays the message "Hello world!" until the user hits Q:

import UI.NCurses

main :: IO ()
main = runCurses $ do
    setEcho False
    w <- defaultWindow
    updateWindow w $ do
        moveCursor 1 10
        drawString "Hello world!"
        moveCursor 3 10
        drawString "(press q to quit)"
        moveCursor 0 0
    waitFor w (\ev -> ev == EventCharacter 'q' || ev == EventCharacter 'Q')

waitFor :: Window -> (Event -> Bool) -> Curses ()
waitFor w p = loop where
    loop = do
        ev <- getEvent w Nothing
        case ev of
            Nothing -> loop
            Just ev' -> if p ev' then return () else loop

Use pkg-config to set linker and include flags.


Force including and linking against ncurses instead of ncursesw. This is only useful on systems that have the ncursesw package installed incorrectly. On most systems this will cause compile- or run-time errors.


Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info


Note: This package has metadata revisions in the cabal description newer than included in the tarball. To unpack the package including the revisions, use 'cabal get'.
