monad-logger-prefix
This package provides an easy way to add prefixes to any
MonadLogger. Here’s a brief example:
{-# LANGUAGE TemplateHaskell #-}
import Control.Monad.Logger
import Control.Monad.Logger.Prefix
main :: IO ()
main = runStdoutLoggingT $ do
$(logDebug) "This one has no prefix."
"foo" `prefixLogs` do
$(logDebug) "This one has a [foo] prefix."
"bar" `prefixLogs` do
$(logDebug) "This one has both [foo] and [bar] prefixes."
The package includes a benchmark demonstrating that there is no performance difference with ordinary logging.
