Declarative Game Programming — slides, videos and code

Earlier this month, Henrik Nilsson & Ivan Perez presented a tutorial at PPDP 14 on Declarative Game Programming.

The goal was to show how real game programming is possible in a purely functional, declarative way. One way of doing …

A new version of Yampa is out (0.9.6)

Yampa is an impressive, arrowized, Functional Reactive Programming (FRP) implementation written in Haskell. We are using it to implement Android games at Keera Studios, and it has been used, among others, to implement the video game Frag (see video …

The most inspiring green screen you will ever see

While Haskell, Idris and other Functional Programming (FP) languages enable writing elegant code, the road to production is, well, bumpy. Writing code for industrial environments has added costs that make certain products too expensive and infeasible in practice. That is …

GUI programming in Haskell “the old way”

As discussed in a previous post, purely functional GUI frameworks may fail to deliver in terms of feature coverage, look-and-feel and codebase scalability. As a result, many programmers turn back to good-old Gtk+ for their user interfaces …

On the state of GUI programming in Haskell

GUI programming in functional and logic languages tends to feel quite hard. There is nothing intrinsic in FP that makes GUI programming extra hard, but when everywhere else  you are surrounded by nice, abstract, compositional, high-level descriptive definitions, working at …
