Description

A safer interface to System.IO.Handle

Synopsis

data Handle (e :: Effects)
withFile :: forall (e1 :: Effects) (es :: Effects) r. e1 :> es => IOE e1 -> FilePath -> IOMode -> (forall (e :: Effects). Handle e -> Eff (e :& es) r) -> Eff es r
hPutChar :: forall (e :: Effects) (es :: Effects). e :> es => Handle e -> Char -> Eff es ()
hPutStr :: forall (e :: Effects) (es :: Effects). e :> es => Handle e -> String -> Eff es ()
hPutStrLn :: forall (e :: Effects) (es :: Effects). e :> es => Handle e -> String -> Eff es ()
hGetLine :: forall (e :: Effects) (es :: Effects). e :> es => Handle e -> Eff es String
hIsEOF :: forall (e :: Effects) (es :: Effects). e :> es => Handle e -> Eff es Bool
hFlush :: forall (e :: Effects) (es :: Effects). e :> es => Handle e -> Eff es ()
unsafeWithHandle :: forall (e1 :: Effects) (es :: Effects) r. e1 :> es => Handle e1 -> (Handle -> IO r) -> Eff es r

If there's a System.IO.Handle-using function you need that isn't included here then you can open an issue to request it be added. In the meantime you can define it yourself with unsafeWithHandle.
