initDebug :: FilePath -> IO ()

Set the file to which debugging output should be written. Though this is called initDebug. Debugging output is not created by default (i.e., if this function is never called.) The target file can not be changed, nor debugging disabled.

trace :: Text -> a -> a

Outputs the given string before returning the second argument.

traceM :: Monad m => Text -> a -> m a

Traces x and returns y.

traceM_ :: Monad m => Text -> m ()

Like traceM, but returns ().

logPutStrLn :: MonadBase IO m => Text -> m ()

logError :: MonadBase IO m => Text -> m ()

logStream :: Show a => Text -> Chan a -> IO ()

error :: Text -> a
