MuniHac 2020: Duncan Coutts - Contravariant Logging: How to add logging without getting grumpy

Title: Contravariant Logging: How to add logging without getting grumpy
Speaker: Duncan Coutts

Logging usually makes me grumpy. It tends to clutter code and adds unnecessary dependencies. It's just not beautiful.

I want to share the good news that there is an approach to logging that does not make me grumpy, and I have used it in a large project where it has worked out well. It is a a relatively new approach based on contravariant functors, that avoids cluttering the code, has a simple general interface that minimises concrete dependencies and still allows a choice of logging backend.

This talk will cover the problems with logging libraries, how contravariant logging improves things and how to apply contravariant logging in your project, with your choice of logging backend.
