co-log-core-0.3.2.2: Composable Contravariant Comonadic Logging Library

This package provides core types and functions to work with the LogAction data type which is both simple and powerful.

newtype LogAction m msg = LogAction
    { unLogAction :: msg -> m ()
    }

The ideas behind this package are described in the following blog post:

• co-log: Composable Contravariant Combinatorial Comonadic Configurable Convenient Logging
