The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Application-managed call stacks, without polluting the business logic
dep-t and dep-t-advice are libraries containing various helpers and utilities for this style of programming. In particular, "dep-t-advice" tries to support what is sometimes called "aspect-oriented programming". In less fancy terms, it provides function decorators that work on functions of any number of arguments. As the functional pearl The Decorator Pattern in Haskell says,

I would argue that passing the context as a positional parameter doesn't have to be tedious. Recently I've been experimenting with ReaderT-less architectures, for example here.

HSpec, Tasty, sydtest, Hunit, ... -> what do you use for writing Haskell tests?
Additionally I have some code to run one Test (single test or test group) from GHCi by passing the function name (run) or a subset of the tests by passing a regexp of the description (runOnly). You can find some of those functions here: https://github.com/etorreborre/registry/blob/main/test/Test/Tasty/Extensions.hs.
