Mining Motivated Trends of Usage of Haskell Libraries

Abstract

We propose an initial approach to mine the usage trends of libraries in Haskell, a popular functional programming language. We integrate it with a novel, initial method to automatically determine the reasons of clients for switching to different versions. Based on these, we conduct a preliminary investigation of trends of usage in Haskell libraries. Results suggest that trends are similar to those in the Java ecosystem and in line with Rogers' theory on the diffusion of innovation. Our results also provide indication on Haskell libraries being all by and large stable.
