Back in March, I crunched the web logs for the Hackage package server (kindly hosted by Galois) to measure for the first time how popular Haskell packages were Hackage.

haskell_universe

4 months later, I’ve rerun the numbers, and have some new data.

Headlines

  • Total Hackage downloads : 1.13 million
  • Total Packages on Hackage : 1470
  • Total Contributors : 400 developers

Essentially unchanged since March in overall rankings.

What if we look at the fastest rising packages though? These are the 25 packages that climbed the most in overall rankings in the 4 months to August 2009, and by how many rankings they improved.

Top 5 fastest rising applications

  1. MazesOfMonad 1266 – Console-based Role Playing Game
  2. bloxorz 1254 – OpenGL logic game
  3. HPong 1166 – A simple OpenGL Pong game based on GLFW
  4. darcs-beta 1131 – beta branch of darcs
  5. Bookshelf 1012 – A simple document organizer with some wiki functionality

Top 5 fastest rising libraries

  1. hashed-storage 1208 – Hashed file storage support code
  2. atom 1200 – A DSL for embedded hard realtime applications
  3. buster 1197 – Almost but not quite entirely unlike FRP GUI library
  4. hack 1190 – a Haskell Webserver Interface
  5. elerea 1174 – A minimalistic FRP library

All these can be installed with:

 $ cabal install <package>

Crunch the Numbers

Here’s the data so you can see how your favourite packages are going:

You can also get the month by month totals:

And don’t forget — the Haskell Platform is cutting into cabal-install’s monopoly on distribution of Haskell code… downloads for that are counted separately.
