Tutorial: 10:00-11:30 (English)

Matthias Fischmann, Alexander Ulrich

Introductory Haskell

Haskell is an elegant and fascinating language that has made purely functional programming practical. This tutorial aims at giving you a sense of direction in the Haskell eco system. We will explain and motivate key language concepts and introduce tools and development techniques as we need them for our examples.

We will start by exploring basic syntax and the Haskell type system in an interactive Haskell environment. The need to write (slightly) larger programs will naturally lead us to the Haskell module system. We will show how to use cabal and the hackage library database to install packages and create our own.

Key language concepts are hard to pick and will depend on the interests of the audience. Some candidates are algebraic data types and pattern matching, polymorphic functions, type classes, monads, GHC language extensions, or programming with typed holes.

Presentation language will be English, but we are happy to discuss your questions in German.


Prerequisites: You should install the Haskell Platform on your laptop. Knowledge of Haskell is not required, but a certain aptitude in at least one other programming language will be helpful.
