Unison.Util.Logger
Description
Small logging library. Typical usage, import qualified:
import qualified Unison.Util.Logger as L
do logger <- L.atomic . L.atInfo . L.scope "worker" . L.toHandle $ stderr L.warn logger "WARNING!!!" L.debug logger "Debug message, will be ignored" let logger2 = L.atDebug logger L.debug logger2 "Debug message, will be printed" logger' <- L.at L.warnLevel
