liftLogLoc :: Loc -> Q Exp Source #

Lift a location into an Exp.

myLogLoc :: Q Exp Source #

Get current LogLoc.

depending on how accurately you want to record source location, you may want to use Logger 's environment, or provide your own on every log.

example usage: info' $myLogLoc "log message"

withLogLoc :: MonadLog LogLoc m => LogLoc -> m a -> m a Source #
