silence :: IO a -> IO a

Run an IO action while preventing all output to stdout.

hSilence :: [Handle] -> IO a -> IO a

Run an IO action while preventing all output to the given handles.

capture :: IO a -> IO (String, a)

Run an IO action while preventing and capturing all output to stdout. This will, as a side effect, create and delete a temp file in the temp directory or current directory if there is no temp directory.

capture_ :: IO a -> IO String

Like capture, but discards the result of given action.

hCapture :: [Handle] -> IO a -> IO (String, a)

Run an IO action while preventing and capturing all output to the given handles. This will, as a side effect, create and delete a temp file in the temp directory or current directory if there is no temp directory.

hCapture_ :: [Handle] -> IO a -> IO String

Like hCapture, but discards the result of given action.
