monad-journal

Pure logger typeclass and monad transformer

What is monad-journal?

monad-journal is a simple but powerful answer to the logging problem. A lot of people think that “logging” is IO-related, while it’s not. Everyone must know MonadWriter , which is perfect to log things in pure computations. The issue is that you can’t access those “things” inside the computation itself. monad-journal exposes a cool typeclass called MonadJournal that enables you to do so.

You can’t perform that action at this time.
