The plugins-auto package

[Tags:bsd3, library]

This library provides support for automatically recompiling and reloading modules into your programs when the source code is modified.

Any program called ghc in your PATH will be used for recompiling.

 import System.IO           (hSetBuffering,stdout,BufferMode(..))
 import System.Plugins.Auto (withMonadIO,initPlugins)
 import Answer

 main :: IO ()
 main = do ph<-initPlugins
         hSetBuffering stdout NoBuffering
         putStrLn "This program interacts with you in a loop."
         putStrLn "Type something, and the program will respond when you hit the Enter Key."
         putStrLn "Modify Answer.hs while interacting and you should see the answers"
         putStrLn "change accordingly."
         let interactiveLoop = prompt ph >> interactiveLoop
   prompt ph = do
      putStr "> "
