logging-effect v1.1.0 Release Notes

  • 💥 Breaking changes:

    • MonadLog no longer has logMessage as a function. It now has logMessageFree which takes a free monoid of log messages. If you were just using logging-effect then this won't affect you, as logMessage still exists with the same signature outside the type class.

    • 🌲 MonadLog now comes with a law that states that logging is a monoid homomorphism. This essentially means that you have to treat all log messages uniformly.

    • Pass-through instances for all "stock" monad transformers have been added (all of transformers, CatchT from exceptions and FreeT/FT from free).

    • WithSeverity now has instances of Traversable and Foldable

    • WithTimestamp now has instances of Eq, Ord, Read and Show.

    ➕ Additions:

    • 🌲 A set of convenience functions have been added for quickly logging with severity. The combinators are: logDebug, logInfo, logNotice, logWarning, logError, logCritical, logAlert and logEmergency.

    • mapLogMessage got a companion function mapLogMessageM that works with monadic tranformations.

    Other

    • 📚 Many documentation bug fixes.

    • INLINEABLE pragmas added.
