Synopsis

Documentation

streamHandler :: Handle -> Severity -> IO (GenericHandler Handle) Source #

Create a stream log handler. Log messages sent to this handler will be sent to the stream used initially. Note that the close method will have no effect on stream handlers; it does not actually close the underlying stream.

fileHandler :: FilePath -> Severity -> IO (GenericHandler Handle) Source #

Create a file log handler. Log messages sent to this handler will be sent to the filename specified, which will be opened in Append mode. Calling close on the handler will close the file.

verboseStreamHandler :: Handle -> Severity -> IO (GenericHandler Handle) Source #

Like streamHandler, but note the priority and logger name along with each message.
