A python logging style log library.
A simple example:
{-# LANGUAGE OverloadedStrings #-} {-# LANGUAGE TemplateHaskell #-} module Main ( main ) where import Logging.Config.Json (getManager) import Logging.Global (run) import Logging.Global.TH (debug, error, fatal, info, logv, warn) import Prelude hiding (error) main :: IO () main = getManager "{}" >>= flip run app logger = "Main" app :: IO () app = do $(debug) logger "this is a test message" $(info) logger "this is a test message" $(warn) logger "this is a test message" $(error) logger "this is a test message" $(fatal) logger "this is a test message" $(logv) logger "LEVEL 100" "this is a test message"
