data Logger

new :: Verbosity -> IO Logger

Create a new logger

flush :: Logger -> forall m. MonadIO m => m ()

Flush the logger (blocks until flushed)

error :: MonadIO m => Logger -> String -> m ()

header :: MonadIO m => Logger -> String -> m ()

message :: MonadIO m => Logger -> String -> m ()

debug :: MonadIO m => Logger -> String -> m ()

Testing utilities

newInMem :: IO (Logger, IO [(Verbosity, String)])

Create a new logger that just stores all the messages, useful for writing tests.
