The GHC reading list

Suppose you want to start contributing to GHC: what should you read by way of background? Here is an annotated list. Please add to it as you come across useful material.

You can ask questions on People are friendly.

General background

  • The GHC Commentary is a Wiki that describes GHC's implementation. It is a Wiki. That means that you can, and should, fix errors and write new chapters.

Types and type inference

  • Modular type inference with local assumptions, Simon Peyton Jones, Dimitrios Vytiniotis, Tom Schrijvers, Martin Suzmann, Journal of Functional Programming, 2011. This epic 83-page JFP paper brings together, in a single uniform framework, a series of our earlier papers on type inference for type systems involving local constraints, including GADTs and indexed type families.
  • Unboxed values as first class citizens, SL Peyton Jones and J Launchbury, Functional Programming Languages and Computer Architecture (FPCA'91), Boston, LNCS 523, Springer Verlag, Sept 1991, pp636-666. How unboxed data types work in GHC.

Please add: System FC, GADTs, kind polymorphism etc


  • Secrets of the GHC inliner, Simon Peyton Jones and Simon Marlow, Journal of Functional Programming 12(4), July 2002, pp393-434. Describes how the Simplifier does inlining.
  • A short cut to deforestation, A Gill, SL Peyton Jones, J Launchbury, Proc Functional Programming Languages and Computer Architecture (FPCA'93), Copenhagen, June 1993, pp223-232. The famous foldr/build rule. Andy's PhD thesis has more.
