ncurses: Modernised bindings to GNU ncurses

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
    render
    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

Flags

Manual Flags

Name	Description	Default
use-pkgconfig	Use pkg-config to set linker and include flags.	Disabled
force-narrow-library	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.	Disabled
force-c2hs-newtype-pointer-hooks	Force using the newtype'd pointer hooks introduced in c2hs 0.18.1. This is only necessary when building with c2hs==0.18.1, as 0.18.2 and later can be auto-detected.	Disabled

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