co-log: Composable Contravariant Comonadic Logging Component

Please log in to watch this conference skillscast.

In this talk I'm going to share key design decisions behind Haskell logging library called co-log.

This library combines multiple algebraic concepts in order to provide convenient and composable solution for the logging problem:

• Semigroup and Monoid
• Contravariant/Divisible/Decidable
• Comonads

I'm also going to show how we use this library in commercial Haskell projects.
